This paper focuses on the relationship between functional ability (FA) and positive affect (PA), a major component of well-being, in sensory impaired very old adults (SI) compared with sensory unimpaired individuals (UI). Previous research mostly suggests a robust causal impact of FA on PA. However, some research, drawing from Fredrickson's broaden-and-build theory, also points to the possibility of an inverse causality between FA and PA. We examine in this paper both of these causal directions in SI as well as UI individuals across a 4. year observation period. Additionally, we checked for the role of negative affect (NA). The T1-T2 sample comprised 81 out of 237 SI individuals (visually or hearing impaired) assessed at T1, with a mean age at T1 of 81.8. years, and 87 UI individuals out of 150 assessed at T1, with a mean age at T1 of 81.5. years. Established scales were used to assess FA, PA, and NA. Using cross-lagged panel analysis to examine the direction of causality, our findings indicate that FA has significant impact on PA in both the SI and the UI group, whereas the alternative causal pathway was not confirmed. Both cross-lagged relationships between FA and NA were non-significant. No group differences in path strengths between SI and UI were present. Our study provides evidence that FA is a key competence for successful emotional aging in vulnerable groups of very old adults such as SI as well as in UI adults in advanced old age. © 2014 Elsevier Inc.

In research on teaching and learning, formative assessments are considered to be an effective method of improving student performance. However, the effects vary strongly depending on learning content, diagnostic procedures, and the form of feedback. In a randomized experimental study conducted in biology classes, it was thus examined whether in the case of a computer-based, formative achievement test detailed indepth feedback (treatment 1) would lead to better learning results than simple feedback (treatment 2). In a control group, students read the identical texts. 10 forms with a total of 261 students attending classes on the lower secondary level participated in the study. Results show that students receiving simple feedback achieve better results in both the posttest and the test of knowledge retained than students receiving treatment 1 or students of the control group. However, when looking more closely at the use made of the feedback, positive achievement effects can be shown for students getting in-depth feedback, too, compared to the control group.

Eating and Weight Disorders | Year: 2012

Eveningness preference is associated with unhealthy eating behaviors. We measured state and trait food cravings in chronotypes in the morning and in the evening. Less Evening (E)-than Morning (M)-types reported to have had breakfast. Accordingly, hours that had elapsed since the last meal were higher in E-than M-types in the morning, but did not differ between groups in the evening. E-types reported higher anticipation of positive reinforcement that may result from eating than M-types in the morning, but both had the same hunger levels. On a trait level, M-types reported more feelings of guilt for giving into cravings compared to E-types. Results suggest that E-types skip breakfast more often than M-types, but this eating pattern does not inevitably lead to more food cravings in the evening or more pronounced habitual cravings. Furthermore, E-types did not experience more hunger in the morning although they had not been eating for a longer time period. Results support findings about a different lifestyle in E-types compared to M-types. © 2012, Editrice Kurtis.

Objectives.Relations between personality and affect are generally regarded as robust. Extraversion is closely linked to positive affect (PA), but not to negative affect (NA), whereas neuroticism is closely linked to NA, but not to PA. We argue in this work that the stress experience associated with age-related vision and hearing impairment may alter this commonly found pattern as compared with sensory unimpaired (UI) older adults.Method.We analyzed data from a sample of severely visually impaired (VI; N = 121), severely hearing impaired (HI; N = 116), and a control condition of sensory UI (grand age mean: 82 years; N = 150).Results.Based on a structural equation modeling approach, we found that the relationship between extraversion and PA was higher in the UI as compared with the sensory impaired groups. In contrast, the strong linkage between neuroticism and NA was not affected by sensory status. Furthermore, we observed a meaningful negative relation between extraversion and NA only in the VI group.Discussion.Findings support the argument that the relationship between personality and affect deserves qualification when chronic vision and hearing impairment is present. © 2012 The Author.

The authors draw on elements of the offer-use-model for the theoretical conceptualization of teaching-learning-contexts in case-based university courses in teacher training. On the offer side, concepts and principles of working with teaching cases are described via a theoretical positioning. On the use side, interdependencies of diverse teaching-learning-models and case media are examined for cognitive stress, motivation, and emotions while learning with cases on the basis of empirical data. The results show that, depending on the respective prioritization, all four forms of casework examined are suitable for novices. In a final part, initial conclusions for a university didactics of casework are discussed on the basis of theoretical considerations and empirical findings.


Eating disorders are serious illnesses predominantly affecting adolescents and young adults. Effective prevention is strongly desired. Estimates of the individual risk are often vague. Therefore, stepwise strategies, such as the German Internet-delivered program YoungEs[s]prit, are appealing. The prospective, randomized controlled intervention study presented here investigated the efficacy of YoungEs[s]prit. The study was conducted in two waves applying an adaptive design. The main outcome was the cumulative incidence rate (according to DSM-IV criteria) over 12 months. Efficacy was statistically tested through survival-analytic methods. Results from the first wave (n = 896) proved the preventive efficacy of YoungEs[s]prit (log rank x2 = 4.29, df = 1, p =. 038,2-sided) with a hazard ratio of 1.67. The cumulative incidence rate of 9.6 % in the control condition was reduced to 5.9 % in the YoungEs[s]prit condition. Results from the second wave (n = 771) could not show any significant differences between the groups (4.8 % vs. 5.6 %, log rank c2 = 0.27, df = 1, p =. 600,2-sided). Taking the results of the two waves together, as required by the adaptive design, the study did not prove efficacy. While the rate of 9.6 % in the first wave corresponds to the estimate of about 10 % reported in the literature, the rate of 4.8 % appears unusually small. Therefore, it was explored whether (1) differences between the samples, e. g., the greater proportion of girls in the second wave, (2) a shorter distance to health services in the second wave, or (3) the possibly increased awareness of eating disorders through the activities in the first wave may have contributed to the differences between the estimates for the two waves. © Hogrefe Verlag, Göttingen 2015.

Universal Access in the Information Society | Year: 2015

Despite numerous studies into the online activities of deaf and hard of hearing (D/HH) users, there has been limited research into their experiences on social networking sites (SNSs), a domain where psychology and computer science intersects. The purpose of this study is to illustrate how one can enhance universal access for D/HH users on the example of SNSs. A model for examining the experiences and preferences of D/HH users of SNSs has been proposed. The model consists of three identity-relevant aspects: (1) belonging to online Deaf communities, (2) communication affinity/preferences for sign and/or written language, and (3) the stigma associated with hearing loss. Based on these aspects, a questionnaire was developed and applied to a study with 46 participants. The findings revealed that the motivation to communicate on SNSs is positively associated with identification with online Deaf communities, an affinity for communication in written language and an affinity/preference for communication in sign language. Better reading comprehension skills, crucial for written communication, are associated with less stigmatic experiences with regard to hearing loss. The model and the findings of this study can help improve understanding D/HH users’ online social interactions and can be used for educational purposes. It may contribute to the discussion of integrating SNSs as communication tools in personal learning environments, which can be an advantage for universal access. © 2014, Springer-Verlag Berlin Heidelberg.

Objectives: The present study examines regulatory dysfunctions and atypical behaviors in young children with various levels of intellectual disabilities. Method: Families were recruited from parent self-help groups. 133mothers completed questionnaires on adaptive competence (VABS-II) as well as temperament and atypical behaviors (TABS). Results: 58% of the children were classified as having regulatory disorders. The TABS scores vary with the child's level of intellectual ability. 80% of children with severe and profound intellectual disabilities were described as highly detached, 50% as under-reactive and dysregulated. Discussion: The results support the validity of the TABS for the assessment of very young children with intellectual disabilities. This group has an increased risk for psychological disturbances and should be included in early mental health screening and intervention services. © 2011 Verlag Hans Huber, Hogrefe AG.

Constructivist approaches to computer science education emphasize that as well as knowledge, thinking skills and processes are involved in active knowledge construction. K-12 computer science curricula must not be based on fashions and trends, but on contents and processes that are observable in various domains of computer science, that can be taught at every intellectual level, that will stay relevant in the longer term, and that are related to everyday language and/or thinking. Only recently, two empirically determined lists, one of central content concepts (algorithm, computer, data, system, etc.) and another of central process concepts (problem solving and problem posing, analyzing, classifying, generalizing, etc.), have become available for computer science education. This paper tackles the problem of finding content and process concepts to be taught in combination. Computer science experts are surveyed in order to identify combinations of content and process conceptsso-called blocksthat are relevant to computer science education. By using cluster analyses, 15 central blocks for teaching computer science in schools are determined. The results of this study may serve as a reference system for the systematic design of instruction in K-12 computer science education. © 2010 IEEE.

This study investigates verbal morphology in Specific Language Impairment (SLI) in German, focusing on past participle inflection. Longitudinal data from 12 German-speaking children with SLI, six monolingual and six Turkish-German sequential bilingual children, were examined, plus an additional group of six typically developing Turkish-German sequential bilingual children. In a recent study (Rothweiler, M., Chilla, S., & H. Clahsen. (2012). Subject verb agreement in Specific Language Impairment: A study of monolingual and bilingual German-speaking children. Bilingualism: Language and Cognition, 15, 39-57), the same children with SLI were found to be severely impaired in reliably producing correct agreement-marked verb forms. By contrast, the new results reported in this study show that both the monolingual and the bilingual children with SLI produce participle inflection according to their language age. Our results strengthen the case of difficulties with agreement as a linguistic marker of SLI in German and show that it is possible to identify SLI from an early sequential bilingual child's performance in one of her two languages. © 2014 Informa UK Ltd.

High temporal revisit frequency over vast geographic areas is necessary to properly use satellite earth observation for monitoring agricultural production. However, this often limits the spatial resolution that can be used. The challenge of discriminating pixels that correspond to a particular crop type, a prerequisite for crop specific monitoring remains daunting when the signal encoded in pixels stems from several land uses (mixed pixels). Naturally, the concept of spatial scale arises but the issue of selecting a proper class legend (the categorical scale) should not be neglected. A framework is presented that addresses these issues and that can be used to quantitatively define pixel size requirements for crop identification and to assess the effect of categorical scale. The framework was applied over two agricultural landscapes. It was demonstrated that there was no unique spatial resolution that provided the best classification result for all classes at once at a given categorical scale. The suitability of pixel populations characterized by pixel size and purity differed for identifying specific crops within tested landscapes, and for one crop there were large differences among the landscapes. In the context of agricultural crop growth monitoring the framework described above can be used to draw guidelines for selecting appropriate imagery, e.g. suitable pixel sizes, and for selecting class legends suitable for accurate crop classification when the interest is only on pixels covering arable land as a prerequisite for crop specific monitoring. The framework could be used to plot the suitability (or accuracy) of pixels as a function of their purity to provide a spatial assessment of classification performance. © 2015 E.

This study examined the predictions regarding the frequencies of activities on social networking sites among D/deaf and hard of hearing people in Germany. Regression analysis revealed that gender, level of education, frequencies of attending social networking sites using smartphones and tablets, as well as purposes of using social networking sites for fun and school or work, account for about 33% of the variances in the frequencies of activities on social networking sites. The findings indicated that men tend to conduct activities on social networking sites more often than women and users with lower levels of education tend to also be more active on social networking sites. Frequent attending social networking sites from smartphones and tablets predicted even more frequent activities on these sites and likewise the using of social networking sites for fun and school or work. These findings could importantly contribute towards actual debates about the possibilities of successfully including social networking sites within the education process. Future research should be attempted to identify which characteristics predict the frequencies of activities on social networking sites in other countries in order to compare the possible effects in countries on these activities and, consequently, users' experiences with social networking sites. © 2015 The Authors.

Abstract Several authors (e.g., Mcniff & Whitehead, 2006; Wallace, 1998) defend the idea that teachers' own involvement in research has the potential to encourage professional growth. Journal writing, teacher logs, written narratives and stimulated recall are some examples of methods that have been used by researchers to encourage and support teachers' reflective practice in teacher-researcher collaborative research. This paper discusses the use of video-stimulated reflection as both a research method and as a means for teacher professional growth. The research findings are drawn from a longitudinal study that investigates a model of Interactive Whiteboard (IWB) technology professional development programme. The research was carried out in the form of seven in-depth case studies with English as a Foreign Language (EFL) teachers in German secondary/vocational schools, as they learn how to integrate the IWB into their teaching. Research data were collected via a variety of research instruments, namely classroom observations and field notes, video recordings of school lessons and teacher training workshops, interviews and video-stimulated reflection. Findings based on the analysis of the copious amount of data gathered indicate that the video-stimulated dialogues were used by the teachers as effective opportunities for reflection, self-evaluation and pedagogical development.

This paper discusses the findings of a case study conducted with an English as a Foreign Language (EFL) teacher at a German secondary school. This case study is part of a research project that investigates the new competencies that EFL teachers need to acquire in order to be able to use the interactive whiteboard (IWB) to develop their practice, informed by a socio-cognitive approach to computer-assisted language learning. The findings point towards various competencies developed by the teacher as she integrated the technology into her teaching, namely: (a) the ability to design IWB-based materials which support opportunities for learner interaction with the whiteboard and with the learning content; (b) the appropriate management of interaction around IWBs in a way that ensures all learners are provided with opportunities to become actively involved; and (c) the ability to find the 'right balance' of technology use.

Objective: To assess if speech perception improves after the upgrade from the TEMPO+ to the OPUS 2 processor. Method: In this retrospective study, 45 subjects (54 ears) implanted with a cochlear implant were upgraded from the TEMPO+ (continuous interleaved sampling + coding strategy) to the OPUS 2 processor (fine structure processing). Before the upgrade, patients were tested with the Freiburg monosyllable (FM) and the Hochmair-Schulz-Moser (HSM) sentence test in quiet and in noise. Four weeks after the upgrade, subjects were again assessed with the same tests. Results: In quiet, mean FM results improved from 62.0% (±21.3%) to 77.8% (±15.2%) and HSM sentences from 69.9% (±26.1%) to 77.9% (±22.1%). In noise, mean FM results improved from 27.3% (±17.1%) to 52.1% (±18.6%) and HSM sentences from 40.4% (±29.1%) to 58.0% (±26.1%). The upgrade to the OPUS 2 was statistically very significant for all speech perception tests (p < 0.001). Additionally, subjects stated that the OPUS 2 initially sounded 'awkward' but that quality and speech perception improved after a certain adaptation time. Conclusion: Speech understanding in quiet and noise significantly improved with the OPUS 2 in all speech perception tests. Copyright © 2011 S. Karger AG, Basel.

Despite the widespread popularity of social networking sites (SNSs) among the deaf and hard of hearing (D/HH), relatively little has been published about how to examine their experiences on SNSs in terms of creating online communities to supportnon-formal education, such as e-learning. With this regard, this paper sets forth a new approach and proposes a theoretical model for examining the experiences of D/HH users of SNSs from the aspects of identity, community building and alliances between communities. Factors, such as hearing loss, educational background, the communication situation and the use of technology are all considered with regard to their meaning for communication at SNSs. The main aim of the model is to examine experiences in informal online spaces and provide a set of guidelines for efficient social and communication support for D/HH online users at non-formal educational process which will in particular serve teachers, designers and developers included in the process. We also point to further research in order to implement the model in the field as well © 2013 The Authors. Published by Elsevier B.V.

This study addressed the classification of multi-temporal satellite data from RapidEye by considering different classifier algorithms and decision fusion. Four non-parametric classifier algorithms, decision tree (DT), random forest (RF), support vector machine (SVM), and multilayer perceptron (MLP), were applied to map crop types in various irrigated landscapes in Central Asia. A novel decision fusion strategy to combine the outputs of the classifiers was proposed. This approach is based on randomly selecting subsets of the input dataset and aggregating the probabilistic outputs of the base classifiers with another meta-classifier. During the decision fusion, the reliability of each base classifier algorithm was considered to exclude less reliable inputs at the class-basis. The spatial and temporal transferability of the classifiers was evaluated using data sets from four different agricultural landscapes with different spatial extents and from different years. A detailed accuracy assessment showed that none of the stand-alone classifiers was the single best performing. Despite the very good performance of the base classifiers, there was still up to 50% disagreement in the maps produced by the two single best classifiers, RF and SVM. The proposed fusion strategy, however, increased overall accuracies up to 6%. In addition, it was less sensitive to reduced training set sizes and produced more realistic land use maps with less speckle. The proposed fusion approach was better transferable to data sets from other years, i.e. resulted in higher accuracies for the investigated classes. The fusion approach is computationally efficient and appears well suited for mapping diverse crop categories based on sensors with a similar high repetition rate and spatial resolution like RapidEye, for instance the upcoming Sentinel-2 mission. © 2015 International Society for Photogrammetry and Remote Sensing, Inc.

Objectives: Gaining a comprehensive picture of the network of constructs in which cognitive functioning is embedded is crucial across the full lifespan. With respect to personality, previous findings support a relationship between neuroticism and cognitive abilities. However, findings regarding old age are inconsistent. In particular, little is known about potentially moderating variables which might explain some of the inconsistency. Our aim was to examine the moderating effect of severe sensory impairment on cross-sectional and longitudinal associations between neuroticism and cognitive functioning. Method: The study sample consisted of 121 visually impaired (VI), 116 hearing impaired (HI), and 150 sensory unimpaired older adults (UI). Mean age was 82.50 years (SD = 4.71 years). Neuroticism was assessed by the NEO Five Factor Inventory, and multiple established tests were used for the assessment of cognitive performance (e.g., subtests of the revised Wechsler Adult Intelligence Scale). Results: Bivariate correlations and multi-group structural equation models indicated stronger relationships between cognitive abilities and neuroticism in both sensory impaired groups (VI and HI) compared to UI older individuals. This relationship was attenuated but still significant in both sensory impaired groups when controlling for age, education and health (number of chronic conditions). In cross-lagged panel models, higher baseline neuroticism was significantly associated with lower cognitive performance four years later in VI and HI individuals. Conclusion: Our results suggest that sensory impairment moderates both cross-sectional and longitudinal associations between neuroticism and cognitive function in advanced old age. © 2015 Taylor & Francis.


Quality of life has been conceptualized as a subjective view of one's feeling of well-being. There is evidence for restraints caused by parenting stress as well as resilience in mothers of children with an intellectual handicap. Specifically, we report on an investigation using the family-related life quality questionnaire (FLQ) in mothers of 26 young boys with Fragile X syndrome. Quality of life is affected by parenting stress as well as individual and social coping resources (hope as a personal trait and quality of family relationships). Child-related variables (age, adaptive competence) had no significant effect on perceived quality of life, child temperament and atypical behavior is related indirectly to maternal life satisfaction as a factor determining the degree of parenting stress. © Vandenhoeck & Ruprecht GmbH & Co.

In this study we examined whether the level of hearing loss is related to the frequency of communication within different situations and performance activities on social networking sites. It was also investigated as to how the frequency of activities were related to the perceived accessibility of these sites. Firstly, the findings revealed that users with lower levels of hearing loss communicated more frequently with hearing persons in the written language than users at higher levels. In contrast, they communicated less frequently with deaf users in sign language than those with higher levels of hearing loss. Secondly, users with lower levels of hearing loss posted videos more frequently than those with higher levels. Thirdly, the more frequently the deaf and hard of hearing users actualized their profiles, posted photos, videos, commented and liked the content, the higher the perceived accessibility of those sites they reported. © 2014 Springer International Publishing.


The importance of prevention has received increasing recognition the world over. In Germany, laws are being enacted and initiatives are taken to make prevention a firmly anchored and integral part of public health care. Preventive measures in early childhood encompass a great breadth and variety of resources. However, any specific preventive measure can only be justified to the extent that it has been proven to be efficient and effective. In Germany small collection of studies have shown the efficacy of psychosocial prevention and early intervention programs. Quality standards can only be determined when empirical evidence has demonstrated the prerequisites for ensuring successful treatment. Criteria for success must include life quality or academic success (school achievement). The stability of the family must also be assessed both before and after the intervention. © Vandenhoeck & Ruprecht GmbH & Co. KG, Göttingen 2012.

The relevance of environmental attitudes is obvious and attitudes towards farm and companion animals and animal welfare in medical research are an important aspect of education. However, both have rarely been linked with each other, and animal attitudes are only sparsely represented within environmental education assessment instruments. Linking these two aspects was the main aim of the present study. The Animal Attitude Scale (AAS), the Intermediate Attitude Scale (IAS), and environmental attitudes based on the 2-MEV-model were used. The 2-MEV model is made of two distinct aspects: preservation and utilization of nature. This relationship between pro-animal attitudes and preservation and utilization has been assessed while controlling for pet ownership, meat consumption, gender and grade level. These covariates are necessary because they have been identified in previous research. Five hundred and forty-three pupils from two different schools in Leipzig, Germany participated in this study. There was a significant influence of gender and grade but not of pet ownership on environmental attitudes. Girls showed higher positive attitudes, and preservation decreased with an increasing grade. Animal attitudes (both AAS and IAS) correlated with > 0.4 with the two environmental attitudes preservation and utilization. It is therefore concluded that environmental attitudes and animal attitudes are closely related constructs. © 2015 by iSER, International Society of Educational Research.

Purpose: To review the psychometric properties of the questionnaires commonly filled in by children and adolescents to measure circadian preference. Methods: We examined the Morningness-Eveningness Questionnaire for Children and Adolescents (MEQ-CA), the Morningness-Eveningness Scale for Children (MESC) and the Composite Scale of Morningness (CSM). We critically analyzed the reliability, in term of internal consistency (through the Cronbach's alpha) and test-retest reliability (through the correlation coefficient), and the type of validation against external criteria (objective assessment of the sleep/wake cycle, body temperature, hormones and other questionnaires). Fifty studies that reported these data were included in the review: 7 studies used the MEQ-CA, 28 used the MESC and 15 used the CSM. Results: The percentage of studies reporting at least acceptable levels of internal consistency was high and similar between the three questionnaires. Evidence for test-retest reliability was scant, since only 3 studies were available; it was at least acceptable for the MESC (two studies with a time interval of 1 month), not acceptable for the MEQ-CA (one study with a time interval of 6 months), while no information was available for the CSM. As regards the validation evidence, the MEQ-CA has been validated by the highest number of external criteria (actigraphy, oral body temperature and other questionnaires), followed by the CSM (cortisol sampling and other questionnaires). The MESC has been validated only against self-report measures. Conclusions: The present state of the art would suggest the use of the MEQ-CA to assess circadian preference in children and adolescents. © 2015 Elsevier Masson SAS.

The accurate measurement of circadian typology (CT) is critical because the construct has implications for a number of health disorders. In this review, we focus on the evidence to support the reliability and validity of the more commonly used CT scales: the Morningness-Eveningness Questionnaire (MEQ), reduced Morningness-Eveningness Questionnaire (rMEQ), the Composite Scale of Morningness (CSM), and the Preferences Scale (PS). In addition, we also consider the Munich ChronoType Questionnaire (MCTQ). In terms of reliability, the MEQ, CSM, and PS consistently report high levels of reliability (>0.80), whereas the reliability of the rMEQ is satisfactory. The stability of these scales is sound at follow-up periods up to 13 mos. The MCTQ is not a scale; therefore, its reliability cannot be assessed. Although it is possible to determine the stability of the MCTQ, these data are yet to be reported. Validity must be given equal weight in assessing the measurement properties of CT instruments. Most commonly reported is convergent and construct validity. The MEQ, rMEQ, and CSM are highly correlated and this is to be expected, given that these scales share common items. The level of agreement between the MCTQ and the MEQ is satisfactory, but the correlation between these two constructs decreases in line with the number of "corrections" applied to the MCTQ. The interesting question is whether CT is best represented by a psychological preference for behavior or by using a biomarker such as sleep midpoint. Good-quality subjective and objective data suggest adequate construct validity for each of the CT instruments, but a major limitation of this literature is studies that assess the predictive validity of these instruments. We make a number of recommendations with the aim of advancing science. Future studies need to (1) focus on collecting data from representative samples that consider a number of environmental factors; (2) employ longitudinal designs to allow the predictive validity of CT measures to be assessed and preferably make use of objective data; (3) employ contemporary statistical approaches, including structural equation modeling and item-response models; and (4) provide better information concerning sample selection and a rationale for choosing cutoff points. © 2013 Informa Healthcare USA, Inc.


Current knowledge on early language development of young children with Down syndrome relies on cross-aged samples. Here we present some data from a longitudinal study of early development in children with Down syndrome ("Heidelberger Down-Syndrom-Studie"). Word acquisition and other milestones of early productive language are assessed via parent report from one to three years of age. The results stress a significant retardation of productive language development, however there is considerable inter-individual variation. The frequency of various word groups, associations among variables and consequences for early intervention are discussed.


A survey of epidemiological findings suggests a significantly increased level of emotional and behavioural problems in children and youth with intellectual disabilities. Some biological and social factors are presented which contribute to this elevated risk for psychopathology. Assessment and intervention planning needs to acknowledge genetic dispositions, and limitations of the capacity of information processing which characterise children with intellectual disabilities. Early intervention may help to prevent emotional and behavioural problems by supporting a positive parent-child relationship, increasing the parents' educational competence and assisting preschool teachers in supporting positive relationships with peers, and promoting social competence. © Vandenhoeck & Ruprecht GmbH & Co.

Over the past decade several studies have demonstrated children's rich knowledge of emotions. In contrast, less is known about children's knowledge about strategies to regulate their own emotional states. While questionnaire data suggest a rather late development of strategies to regulate emotions, not beginning before middle childhood, theory-of-mind research suggests the possibility of an earlier development. The present study examines whether children from age three on are able to distinguish effective from ineffective strategies of emotion regulation. A total of 64 children (16 3-, 4,-5-, and 6-year-olds) were given six stories all depicting a child protagonist facing a fear-eliciting situation. For each story, two effective and two ineffective strategies were presented. The children's task was to judge whether the strategy would be helpful for not feeling scared. With the exception of the 3-year-olds, children of all age groups were better in understanding the mental strategies than the behavioral strategies. Thus, the results are in accordance with theory of mind research and indicate that recognizing effective behavioral and mental strategies begins to develop from three years onward. © Vandenhoeck & Ruprecht GmbH & Co.

Alarm calling has been interpreted from the viewpoint of parental investment and nest defence. Calling should increase with an increasing value of the brood to the caller or with increasing vulnerability of the brood. Parental alarm calling might also be viewed from assessment-management with callers using vocalisations to elicit affective responses in others, e.g. in silencing offspring. I examined parental alarm calling in the Cyprus Wheatear (Oenanthe cypriaca) at different developmental stages. The Cyprus Wheatear produces two alarm calls, but one is emitted only during a short period of the year (type II alarm call). The commoner alarm call (type I alarm call), however, is used year-round. Predation was simulated using consistent approach by human observers. The brood cycle was divided into (I) incubation, (II) nestling, (III) early fledging, and (IV) late fledging. Type I calls increased from phases I to III, and decreased afterwards. Type II calls were absent during incubating and occurred during nestling and early fledging stages. As a conclusion, I suggest that the type I alarm call might be used to alert the mate, deter the predator and signal strength of nest defence, while the type II alarm call is addressed to offspring. © 2012 Springer-Verlag Berlin Heidelberg and ISPA.

We examine whether sensory impairment moderates the association between cognitive performance and well-being and, if so, whether such a moderation effect is due to a mediating mechanism via everyday competence in sensory-impaired individuals. Our sample consisted of visually-impaired (VI, n = 121), hearing-impaired (HI, n = 116), and sensory-unimpaired older adults (UI, n = 150), with a mean age of 82.50 years (SD = 4.71 years). Multiple measures of well-being (life satisfaction, affect, loneliness) as well as several established tests of cognitive performance were included.We found stronger relationships between cognitive performance and well-being in the HI and VI group than in UI individuals. Furthermore, the relationship was mostly mediated by everyday competence both in VI and HI older adults. © 2015 Hogrefe Publishing.


Problem: Because in future more and more hearing-impaired children will go to school in inclusive settings, the life quality of this group constitutes a significant psychosocial indicator for participation in societal life. The Inventory of Life Quality of Children and Youth (ILC) was tested to examine its usefulness in diagnosing hearing-impaired children. Method: The ILC was filled in by 212 children. The procedure's inter-item-correlations, factorial structure and reliability were tested, and also the level of life quality compared to the procedure's standardization sample. Determined in addition were interrelations with sociodemographic variables, children's competencies and children's experienced participation at school. Results: For hearing-impaired children as well, the ILC with all its relevant statistic values proves to be a procedure for measuring life quality that provides very satisfying results comparable to those of available standardization samples. The level of life quality of the tested sample is not impaired as compared to that of with children with good hearing. As expected, there are some significant relations to other variables, such as communicative competence, intelligence, academic achievements, and participation. Conclusion: The ILC provides a valid screening procedure that can be applied in the diagnosis of hearing-impaired children to measure the psychosocial well-being of hearing-impaired children in general education classrooms, and to get evidence for timely interventions. © 2010 by Verlag Hans Huber, Hogrefe AG.

Background: While suicide is the second leading cause of death among young people in most industrial countries, non-fatal suicidal behaviour is also a very important public health concern among adolescents. The aim of this study was to investigate gender differences in prevalence and emotional and behavioural correlates of suicidal behaviour in a representative school-based sample of adolescents. Methods. A cross-sectional design was used to assess suicidal behaviour and various areas of emotional and behavioural problems by using a self-report booklet including the Youth Self-Report. One hundred sixteen schools in a region of Southern Germany agreed to participate. A representative sample of 5,512 ninth-grade students was studied. Mean age was 14.8 years (SD 0.73); 49.8% were female. Results: Serious suicidal thoughts were reported by 19.8% of the female students and 10.8% of the females had ever attempted suicide. In the male group, 9.3% had a history of suicidal thoughts and 4.9% had previously attempted suicide. Internalizing emotional and behavioural problems were shown to be higher in the female group (difference of the group means 4.41) while externalizing emotional and behavioural problems slightly predominated in male students (difference of the group means -0.65). However, the total rate of emotional and behavioural problems was significantly higher in the adolescent female group (difference of the group means 4.98). Using logistic regression models with suicidal thoughts or attempted suicide as dependent variables, the pseudo-R 2 of gender alone was only 2.7% or 2.3%, while it was 30% or 23.2% for emotional and behavioural problems measured by the YSR syndrome scales. By adding gender to the emotional and behavioural problems only an additional 0.3% of information could be explained. Conclusions: The findings suggest that gender differences in non-fatal suicidal behaviour among adolescents can to a large extent be explained by the gender differences in emotional and behavioural problems during this age. © 2011 Kaess et al; licensee BioMed Central Ltd.

• Objective: To summarize the current state of research regarding the experience of age-related vision and hearing impairment. • Methods: Review of the literature. • Results: Negative consequences of age-related vision and hearing impairment manifest in the domains of health and longevity, everyday competence, cognitive functioning, social functioning, and subjective well-being. However, while vision impairment strongly impacts everyday competence, the burden of hearing impairment can mainly be found in the social domain. Psychosocially framed intervention research has shown promising findings, but many studies rely on small samples or do not include a control condition. • Conclusions: Although more research is needed, it is clear that traditional rehabilitation programs targeting age-related vision and hearing impairments need a strong psychosocial component.

The association between circadian preference and academic achievement has been assessed through a systematic review and meta-analysis. The literature searches retrieved 1647 studies; 31 studies, with a total sample size of 27309 participants, fulfilled the inclusion criteria and were included in the meta-analysis. With reference to all these 31 studies, before running the meta-analysis, the sign of the correlation between the investigated variables was set in a way that a positive correlation showed that eveningness was related to worse academic performance. The meta-analysis yielded a small overall effect size of 0.143 (CI [0,129; 0,156]) under a fixed effects model (Z=20.584, p<0.001, I=72.656; Q=109.715) and of 0.145 (CI [0.117; 0.172]) under a random effects model (Z=10.077, p<0.001). A random effects model with a grouping variable (participants) revealed 15 studies based on school pupils and 16 on university students. The random model showed a higher effect size in school pupils (0.166, CI from 0.127 to 0.206) compared to university students (0.121, CI from 0.080 to 0.163). Self-report measures of grades revealed a stronger effect size (0.171; CI: 0.137 to 0.206; N=20) compared to objective measures (0.093; CI: 0.047 to 0.140; N=19). Overall, the present results suggest that evening orientation is associated with a worse academic performance, both in school pupils and university students; for the first time, it has been shown that such relationship changes over time, being weaker in university students. © 2015 Informa Healthcare USA, Inc.

Drunkenness among adolescents represents a significant problem and is associated with adverse consequences. A Licensing Act, which prohibits the dispensing of alcoholic beverages to visibly intoxicated individuals, was introduced in Germany to curb excessive drinking. The objective of the study was to explore whether it is possible for barkeepers and security personnel to correctly estimate the alcohol level (AL) of adolescents merely based on their outer appearance and self-report. In a commercial dance club, 89 adolescents reported their past and current alcohol consumption and estimated their own AL. Their breath alcohol level was measured with a breathalyzer. The sample was divided into "moderate drinkers" and "binge drinkers." Barkeepers and security personnel spoke to and examined the adolescents in order to estimate the adolescents' AL. Professional staff underestimated the ALs of adolescents in 60.7 % of all cases. Estimates of the personnel showed greater deviations from the measured AL of the adolescents as compared to estimates of the adolescents themselves, especially in the group of binge drinkers (t = 2.764; p = 0.009). Conclusion: It seems that adolescents suffer less from observable effects of alcohol, such as sedation or impairment of motor function. Consequently, we do not recommend the application of the Licensing Act to adolescents, but suggest its replacement by other restrictions and prevention measures. © 2012 Springer-Verlag.

Sleep timing of humans can be classified alongside a continuum from early to late sleepers, with some people (larks) having an early activity, early bed, and rise times and others (owls) with a more nocturnally orientated activity. Only a few studies reported that morningness-eveningness changes significantly during the adult lifespan based on community samples. Here, I applied a different methodological approach to seek for evidence for the age-related changes in morningness-eveningness preferences by using a meta-data from all available studies. The new aspect of this cross-sectional approach is that only a few studies themselves address the age-related changes of the adult lifespan development, but that many studies are available that provide exactly the data needed. The studies came from 27 countries and included 36,939 participants. Age was highly significantly correlated with scores on the Composite Scale of Morningness (r = 0.70). This relationship seems linear, because a linear regression explained nearly the same amount of variance compared to other models such as logarithmic, quadratic, or cubic models. The standard deviation of age correlated with the standard deviation of CSM scores (r = 0.55), suggesting when there is much variance in age in a study; in turn, there is much variance in morningness. This meta-analytical approach shows that morningness-eveningness changes across the adult lifespan and that older age is related to higher morningness.


During their staging at stopover sites, migrants may compete with resident species over food resources ("resource competition hypothesis"), or migrants feed on surplus that is not utilised by the residents. Here, I studied foraging behaviour of the Cyprus Wheatear, Oenanthe cypriaca, a ubiquitous and common species with a broad niche range, on Cyprus, which is an important stopover site during intercontinental spring migration. During adverse weather conditions, perch height and aerial sallying were lower and perch/pounce activity was higher. Average perch height and sallying increased over the season, while perch-pounce foraging decreased. There was no influence of clock time. Bivariate correlations suggested an influence of migrants on perch height but not on other variables. Using a series of regression analyses with sex, time of day, date, weather conditions and number of migrants as independent variables revealed no influence of the number of migrants on the foraging behaviour of the Cyprus Wheatear. This suggests that the abundance of migrants does not lead to a change in the behaviour of the Cyprus Wheatear. © 2013 Taylor & Francis.

The study aimed at testing chronotype and gender differences in the time of day when humans feel the greatest need for sex and the time of day they actually undertake sexual activity. A Polish sample of 565 participants aged between 18 and 57 was tested. In females, regardless of chronotype, the greatest need for sex occurred between 18:00 and 24:00, but a secondary peak appeared only in morning types at 6:00-9:00. In males, the greatest need for sex occurred either in the morning or evening hours: in evening types at 9:00-12:00 and 18:00-3:00; in neither types at 6:00-9:00 and 18:00-24:00; in morning types at 6:00-12:00 and 18:00-24:00. Considering time of day when subjects were undertaking sexual activity most frequently, this appeared between 18:00 and 24:00 for all the participants, and prolonged until 3:00 at night in evening type males. Morningness preference was more strongly related to the timing of need for sex than to the timing of actual sexual activity (r=-0.275 vs. r=-0.174), while the timing of desire and the timing of sexual activity were positively, but moderately related (r=0.320). © Informa Healthcare USA, Inc.

Purpose: Previous research on psychosocial adaptation of sensory-impaired older adults has focused mainly on only one sensory modality and on a limited number of successful aging outcomes. We considered a broad range of successful aging indicators and compared older adults with vision impairment, hearing impairment, and dual sensory impairments and without sensory impairment. Design and Methods: Data came from samples of severely visually impaired (VI; N = 121), severely hearing-impaired (HI; N = 116), dual sensory- impaired (DI; N = 43), and sensory-unimpaired older adults (UI; N = 150). Participants underwent a wide-ranging assessment, covering everyday competence, cognitive functioning, social resources, self-regulation strategies, cognitive and affective well-being, and 4-year survival status (except the DI group). Results: The most pronounced difference among groups was in the area of everyday competence (lowest in VI and DI). Multigroup comparisons in latent space revealed both similar and differing relationship strengths among health, everyday competence, social resources, self-regulation, and overall well-being, depending on sensory status. After 4 years, mortality in VI (29%) and HI (30%) was significantly higher than in UI (20%) at the bivariate level, but not after controlling for confounders in a multivariate analysis. Implications: A multidimensional approach to the understanding of sensory impairment and psychosocial adaptation in old age reveals a complex picture of loss and maintenance. © The Author 2013.

Computer-assisted formative assessments with multiple-tier items are a valid instrument for diagnosing students' conceptual understanding in learning domains with well-structured declarative knowledge (e.g. science education). However, it is unknown how feedback on multiple-tier items can improve learning success. Therefore, we assessed (1) predictors of students' perception and use of elaborated feedback, and (2) if feedback content (elaborated, verification, control) matters in explaining students' achievement in post- and retention tests. We developed computer-assisted formative tests for a teaching unit on evolutionary adaptations. Three treatment groups were employed with varying feedback content: Treatment 1 (T1) was an elaborated instruction-based feedback, T2 was a dichotomous verification feedback, and T3 (control) consisted of reading appropriate texts (no formative assessment and no feedback). Afterwards, T1 was separated into one subgroup with pupils who used the feedback thoroughly (T1A) and a subgroup that did not use the feedback (T1B). Ten secondary classrooms were used and 261 pupils participated in this study. Each student in each classroom was randomly assigned to one treatment group. Correlation and univariate regression analysis showed that perception and use of elaborated feedback were related to intrinsic motivation and self-reported grades. Multivariate analysis of covariance was applied to check treatment effects on post-tests and retention tests as dependent variables. Results revealed that verification feedback (T2) and elaborated feedback when students did use it (T1A) was superior to no feedback (T3) and elaborated feedback when students did not use it (T1B). Implications for the design of multiple-tier diagnostic assessments are discussed. © 2016 Elsevier Ltd. All rights reserved.

The relationship of temperament, atypical behaviors, and adaptive behavior of young boys with Fragile X syndrome on mothers' parenting stress was analyzed. Twenty-six boys with Fragile X syndrome (30-88 months of age) participated. The overall development of the participants was significantly delayed with a specific profile of adaptive behaviors (i.e., strengths in domestic daily living) and behavioral challenges (i.e., high levels of detachment and hypersensitive or hyperactive behavior). Approximately 90% of the mothers reported very high levels of parenting stress. Correlational and regression analyses revealed that temperament and atypical behavior contributed significantly to the level of parenting stress. Implications for early intervention services for families with a child with Fragile X syndrome were discussed. © Taylor & Francis Group, LLC.

"Non-native organisms are a major threat to biodiversity". This statement is often made by biologists, but general conclusions cannot be drawn easily because of contradictory evidence. To introduce pupils aged 11-14 years to this topic, we employed an educational program dealing with non-native animals in Central Europe. The pupils took part in a lesson giving general information about the topic, followed by a species identification quiz. Attitude, emotions and state of knowledge of each pupil were surveyed throughout the program using standardized questionnaires (pre-/post- and follow up tests). One week after the first lesson, a field trip followed, focusing on one out of two non-native bird species in the city of Heidelberg, Baden-Württemberg, Germany. The first species was the Ring-necked Parakeet (Psittacula krameri) from the Indian subcontinent, and the second species was the East Asian Swan goose (Anser cygnoides). Life history information was delivered through a teacher and own observations during the excursions and after four weeks, the newly gained knowledge was tested in a third lesson. The "goose group" scored higher in goose-related questions, whereas the "parakeet-group" scored higher in their topic. The most impressive aspect of the whole program was, that the pupils rated the field trip per se as highest, and secondly, learning about unfamiliar species. Interestingly, the general attitude towards non-native species did not change as a result of this educational intervention. © 2010 IJESE.

Morningness-eveningness preference can be measured by questionnaires, such as the Composite Scale of Morningness (CSM). Here, we used data from a retrospective sleep-wake diary including many aspects of social life during the preceding week to establish further convergent quality for the CSM. Participants (N = 570) were students of social science from universities in Warsaw and Heidelberg. Morning-orientated students woke up, got up and went to bed and slept at earlier hours than more evening-orientated students, and experienced less social jetlag. Exceptions were sleep onset latency and sleep duration which seemed unrelated to morningness-eveningness. More morning subjects, as indicated by CSM scores, had earlier first contact with another person, went outdoors earlier and started work earlier. They also had earlier timing of breakfast, lunch and dinner. The correlations between CSM scores and activity indices did not differ between Poland and Germany. The data suggest that morning-orientated students exhibiting greater morningness preference do, indeed, live on an earlier schedule. © 2014 Taylor & Francis.

The reduced version of the Morningness-Eveningness Questionnaire (rMEQ) is widely used to study morningness orientation. The fuzzy analysis helps mapping outputs of the questionnaire irrespective of linguistic and cross-cultural aspects in an efficient manner. In the present study, the rMEQ was administered to a convenience sample of university students (N = 2660) in four different countries and responses have been quantified by using an adaptive neuro-fuzzy inference system for the cross-cultural comparison and then the quantified values are used to construct the proposed model. The cross-country fuzzy morningness value showed that environmental temperature has definite influence on morningness orientation but other factors may also have a role. The developed model can be universally used to analyse the morning-evening orientation of people more precisely without cross-language and cross-cultural biases and it would become a potential tool for interpretation of morningness scores and counselling of individuals. © 2014 © 2014 Taylor & Francis.

Morningness-eveningness or circadian typology can be viewed as an interesting aspect of individual differences. Morningness-eveningness is a preference for a given time of day for physical or mental performance, but also reflects aspects of affect. Here, we used seven different measures to assess differences in morningness-eveningness between Germany, Slovakia and India. The hypothesis was that Indians should be earliest chronotypes, followed by Slovakia and then Germany, because of higher temperatures in India, and the fact that Slovakia is located farther east compared to Germany. We applied the Composite Scale of Morningness (CSM), the Circadian Energy Scale (CIRENS), the CAEN Chronotype Questionnaire (CCQ), and habitual sleep-wake variables to calculate sleep duration, midpoint of sleep and social jetlag. Sample sizes were N = 300 (Germany), N = 482 (Slovakia) and N = 409 (India). Country had the strongest influence on morningness-eveningness. Germans were latest chronotypes and differed in all seven measures from Indians but differed from Slovakians only in the energy level at the evening and midpoint of sleep. Slovakians and Indians differed in all measures but the energy level (CIRENS). Women scored higher on the CSM, lower on CIRENS, lower on the morningness-eveningness (ME) scale, but higher on distinctness (DI) scale. Women slept longer and had an earlier midpoint of sleep. © 2014 International Union of Psychological Science.

Analysing companion species from unrelated taxa concentrated so far mainly on identifying biosurrogacy in terms of conservation biology. No study has investigated companion bird and plant species to predict breeding and migrant habitats of a bird genus. In this study we recorded and analysed companion bird and plant species of the breeding bird Cyprus Wheatear Oenanthe cypriaca and four migranting Oenanthe species on Cyprus. We found characteristic companion species in Cyprus Wheatear's, Wheatear migrant's and in control habitats where no Wheatears were present. We show that plant and bird companion species can be used as discriminating factors to predict breeding and migrant habitats of the genus Oenanthe on Cyprus. Furthermore, habitat preferences of Cyprus Wheatear's companion species indicate bushy and vegetation rich habitats avoiding woodland on the one hand and managed farmland on the other hand. In comparison, migrant Wheatear and control habitats were characterised by companion species pointing to a high openness. These results support former habitat descriptions of Cyprus Wheatear and migrant Wheatears. In more general, this study shows that companion species from unrelated taxa can be used to predict breeding and migrant habitats of a bird genus. © The Ecological Society of Korea.

The paper describes an object-based method to detect destroyed buildings as a consequence of an earthquake. The investigation is based on the analysis of remotely sensed raster and vector-based data. The methodology includes three main steps: generation of features defining the states of buildings, classification of building state and data import in GIS. This paper concentrates on the first step of the three, the generation of features. The appropriately selected features are indispensable for the following successful classification. The described methodology is applied to remotely sensed images of areas that had been subject to an earthquake. Our preliminary results confirm the potential of the proposed approach for detection of the building state. The change detection methodology has been developed solely with Open Source Software. GRASS GIS is involved for vector and raster data processing and presentation. Programming languages Python and Bash are used to develop new GRASS-modules. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

Satellite remote sensing is an invaluable tool to assess the status and changes of irrigated agricultural systems. Agricultural sites are among the most heterogeneous sites at the landscape level: spatial pattern of agricultural fields, within-field heterogeneity, crop phenology and crop management practices vary significantly. Highly dynamic objects (crops and crop rotations) result in large temporal variability of surface spatial heterogeneity. Technological advances have opened the possibility to monitor agricultural sites combining satellite images with both high spatial resolution and high revisit frequency, which could overcome these constraints. Yet depending on the field sizes and crop phenology of the agricultural system observed, requisites in terms of the instrument's spatial resolution and optimal timing of crop observation will be different. The overall goal is to quantitatively define region specific satellite observation support requirements in order to perform land use classification at the field basis. The main aspect studied here is the influence of spatial resolution on the accuracy of land use classification over a variety of different irrigated agricultural landscapes. This will guide in identifying an appropriate spatial resolution and input parameters for classification. The study will be performed over distinct locations in irrigated agro-ecosystems in Central Asia, where reliable information on agricultural crops and crop rotations is needed for sustainable land and water management. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).


For reasons of prevention medical examinations of school beginners are brought forward up to 2 years before school enrollment. In Baden- Württemberg HASE is used as screening for risks in the acquisition of language and in learning to read and write. Up to now norms were insufficient for the age-group of 4;0-4;5 years. Based on the results of 3 354 children the norms for this age-group could be recalculated and are now available as percentile ranks, T-scores, and C-scores. © 2013 Georg Thieme Verlag KG Stuttgart - New York.

Lexical development in first language (L1) Turkish and second language (L2) German in two- to three-year-old children was examined, using parental vocabulary checklists in Turkish and in German. Children showed strong Turkish dominance in the number of lexical items they produced, which was due to the more frequent exposure to Turkish and higher quality of the input. Their vocabulary in Turkish and German comprised a largely different conceptual make-up, as evidenced by a high conceptual count of items across languages. Translation equivalents made up around 10% of the Total Vocabulary. An exemplary analysis of six noun categories showed that the more domestically oriented categories (Furniture, People) were represented more strongly in Turkish vocabularies, while the Food and Drink category contributed equally to both languages. In Turkish, 18% of words were verbs, whereas in German, verbs constituted only 7% of the children’s vocabularies. A comparison between the parent checklists TIGE (developed for Turkish monolingual children in Turkey) and TILDA (developed for Turkish children growing up in Germany) revealed conceptual differences, which can be attributed to culture-specific developments and use of specific lexical items in the two countries. Therefore, language- and culture-specific instruments should be used to assess early vocabulary skills. © 2016 Informa UK Limited, trading as Taylor & Francis Group

Accurate crop identification and crop area estimation are important for studies on irrigated agricultural systems, yield and water demand modeling, and agrarian policy development. In this study a novel combination of Random Forest (RF) and Support Vector Machine (SVM) classifiers is presented that (i) enhances crop classification accuracy and (ii) provides spatial information on map uncertainty. The methodology was implemented over four distinct irrigated sites in Middle Asia using RapidEye time series data. The RF feature importance statistics was used as feature-selection strategy for the SVM to assess possible negative effects on classification accuracy caused by an oversized feature space. The results of the individual RF and SVM classifications were combined with rules based on posterior classification probability and estimates of classification probability entropy. SVM classification performance was increased by feature selection through RF. Further experimental results indicate that the hybrid classifier improves overall classification accuracy in comparison to the single classifiers as well as user's and producer's accuracy. © 2012 SPIE.


Onset of language development begins early and even prenatally. In the first 3 years of life children enter into language development at different levels and show a dramatic development with respect to production and reception. Although language development as such appears to be very robust, developmental language impairments are common and are associated with severe consequences for further child development. Delays in language development can first be identified at the age of 2 years. These can either be the expression of late talking, which is a circumscribed delay in language development or an indication of other disorders and impairments (e.g. cognitive impairments, sensory disorders and disorders from the group of autistic forms). Not all late talkers develop a language impediment disorder as a consequence; however, in individual cases so far only very limited reliable predictions can be made. In addition, early diagnosis is made more difficult because not all children who later develop a circumscribed disorder in language development are already conspicuous at the age of 2 years; therefore, screening at 2 years alone is insufficient. © 2016, Springer-Verlag Berlin Heidelberg.

In recent years natural disasters have had an increasing impact leading to tremendous economic and human losses. Remote sensing technologies are being used more often for rapid detection and visualization of changes in the affected areas, providing essential information for damage assessment, planning and coordination of recovery activities. This study presents a GIS-based approach for the detection of damaged buildings. The methodology is based on the integrated analysis of vector data containing information about the original urban layout and remotely sensed images obtained after a catastrophic event. For the classification of building integrity a new 'Detected Part of Contour' (DPC) feature was developed. The DPC feature defines a part of the building contour that can be detected in the related remotely sensed image. It reaches maximum value (100%) if the investigated building contour is intact. Next, several features based on the analysis of textural information of the remotely sensed image are considered. Finally, a binary classification of building conditions concludes the change detection analysis. The proposed method was applied to the 2010 earthquake in Qinghai (China). The results indicate that a GIS-based analysis can markedly improve the accuracy of change detection analysis. The proposed methodology has been developed solely within the Open Source Software environment (GRASS GIS, Python, Orange). The employment of Open Source Software provides the way for an innovative, flexible and cost-effective implementation of change detection operations. © 2012 SPIE.


Foster and adoptive parents of 71 children with fetal alcohol syndrome (FAS) report on developmental and behavioral characteristics, family stress, coping resources and their satisfaction with support. The data reveal an elevated rate of social and emotional problems in the children. In spite positive individual and social resources, the foster and adoptive parents feel a high level of caregiver stress. 30 % of them rate the support they receive from pediatric, therapeutic or educational services as lower than expected. Specifically, they miss early information on the diagnosis, professional knowledge and support for the special challenges of education and managing behavioral problems in their collaboration with social support agencies. © Vandenhoeck & Ruprecht GmbH & Co.

Recent CALL research suggests that the arrival of new technologies in the language classroom has led to an increased dominance of the socio-constructivist paradigm (Felix, 2006). Borg (2006) suggests, however, that the hegemony of this paradigm may not extend beyond well-researched university and private ESL contexts. The present study tests this prediction by examining the integration of interactive whiteboard (IWB) technology by non-native speaking teachers of EFL in state schools in France and Germany. Teachers' cognitions were investigated via longitudinal qualitative empirical data, involving classroom observations, video recordings of lessons, in-depth interviews and video-stimulated reflections. Findings suggest that in spite of communicatively oriented, socio-constructivist training, teachers used IWB technology to implement a variety of different approaches. The paper traces teachers' use of different models, from traditional grammar-translation to more communicative and constructivist models of task and project-based learning. It shows how individual teachers' approaches are shaped by a variety of factors, such as teachers' teaching and learning experience, pedagogical beliefs and institutional demands. These findings illustrate the complexities of technology integration in CALL and show how teachers often adapt or ignore hegemonic pedagogies to construct their own representations of the technology which are more in line with their curricular and personal goals. © 2012.

The climatic changes on earth may have serious implications for the carbon (C) cycle in the terrestrial Arctic throughout the 21st century. Arctic vegetation takes up carbon dioxide (CO2) from the atmosphere producing biomass. In a cold and often moist soil environment, dead organic matter is preferentially preserved as soil organic matter (SOM) due to the inhibition of decomposition processes. However, viable soil microbes exhale huge amounts of CO2 and methane (CH4) annually. Hence, Arctic ecosystems exhibit annual fluxes of both carbon-based (CO2 and CH4) greenhouse gases (GHGs) that are in an order of magnitude of millions of tons. Rising Arctic temperatures lead to the degradation of much of today's permafrost in the long run. As a result, large quantities of frozen SOM may become available for decomposers, and GHGs that are entrapped in permafrost may be released. At the same time, warming tends to stimulate the growth, development, and reproduction of many Arctic plants, at least transiently. The present northward migration of boreal shrubs and trees into southern tundra areas may be amplified by that, increasing the ecosystems' gross primary production and, thus, their C sequestration. On the other hand, rising temperatures boost SOM decomposition and microbial respiration rates. In general, soil temperature and soil moisture are key environmental variables to control the intensity of aerobic and anaerobic respiration by microbes, and autotrophic respiration by plants.On the basis of published data on Arctic CO2 and CH4 fluxes, the calculations on the terrestrial C-based Arctic GHG balance made in this review reveal a current annual GHG exchange that ranges between a weak storage of = 225 Tg CO2 equivalent (eq.) y-1 and a huge release of = 1990 Tg CO2 eq. y-1. Hence, the Arctic GHG balance does apparently already contribute positively to the climatic changes at present. Regarding the future, the relative development of the uptake and release of CO2 and CH4 by northern ecosystems is fundamental to the overall GHG status of the Arctic under scenarios of continued climate change. © 2010 WILEY-VCH Verlag GmbH & Co.

Background: By considering their general development, 2-year-old children with delayed speech development (late talkers, LT) were examined and described with respect to linguistic competence and hearing. Methods: Initially, 50 monolingual German speaking LT (age: 23-28 months) were recruited. In addition to audiological tests (impedance testing, otoacoustic emissions, reaction audiometry), language development status test was performed (clinical impression during examination, expressive vocabulary: FRAKIS, receptive competence: SETK-2). Results: After exclusion of 10 children with general retarded development (3 premature infants, 2 children with suspicion of autism and 2 children with infantile brain damage) 33 LTs with normal hearing were included. The expressive vocabulary (FRAKIS) of 82% of these 33 LTs were below the normal range. 39% showed deficits in language comprehension tests (SETK-2) although parental reports mentioned language comprehension problems in only 3 LT. No correlation was found between vocabulary (FRAKIS) and language comprehension (SETK-2). Conclusion: The clinical collective in this study showed severely affected children with a high percentage of other abnormalities and speech perception problems in many cases. Despite normal hearing, vocabulary and especially speech comprehension should also be tested. LT with language comprehension problems require early developmental psychological investigation in order to prevent language and general developmental limitations. Only in this way, remedial instruction adapted to the developmental level can be initiated. © Georg Thieme Verlag KG Stuttgart · New York.

Black-capped chickadees Poecile atricapillus alter the number of D notes of their chick-a-dee call to reflect urgency and threat. Here, I tested whether heterospecific responses of an allopatric species to these mobbing calls occur. Heterospecific chickadee mobbing calls and songs from North America were broadcast to European great tits (Parus major) and compared with conspecific mobbing calls. During conspecific mobbing playbacks, all great tits approached the speaker, during the heterospecific "chick-a-dee" playbacks, 63.3% individuals approached the speaker, while during the song playback, only 31.3% of the great tits approached the speaker. Minimum distances of great tits were lower during conspecific mobbing calls compared to allopatric chick-a-dee calls and to allopatric chickadee song. Also, minimum distances were lower when comparing allopatric chick-a-dee calls and chickadee song. Great tits approached the speaker on average down to (mean ± SE) 20.0 ± 1.8 m during playbacks of 1-4 D elements, to 17.7 ± 2.0 m during playbacks of 5-7 D elements and down to 11.5 ± 2.0 m during playbacks of 8-11 D elements. The number of D notes was inversely related to minimum distance. Thus, the urgency message encoded in the D notes was perceived also by an allopatric but phylogenetically related European species, suggesting that the heterospecific response is possibly phylogenetically conserved. © 2012 Springer-Verlag.

Passerine mobbing calls are, in part, addressed to conspecific and heterospecific prey individuals, and may encourage them to join a flock mobbing a predator. We examined whether conspecific and heterospecific individuals differ in their response to natural and manipulated contact and mobbing calls. We assumed that conspecifics would be more sensitive to slight variation in call elements and manipulations, whereas heterospecifics most likely cannot distinguish subtle differences. We used chaffinch, Fringilla coelebs, contact and mobbing calls, which differ only slightly in structure (start and maximum frequency and frequency bandwidth). Despite these subtle differences in call parameters, mobbing calls of chaffinches could be transformed into artificial contact calls by using fewer elements/min, and vice versa. Contact calls could be transformed into mobbing calls by reducing the pauses between the single elements. The results show that intense calling attracted more conspecific and heterospecific prey individuals than less intense playbacks of the calls made of the same elements. Responses to natural calls compared to manipulated calls were similar in minimum distance to the speaker in conspecifics and heterospecifics, in the number of conspecific and heterospecific individuals alerted and in the number of heterospecific species attracted. The frequency of calls per time unit was the most significant factor affecting whether other birds interpreted the vocalization as a mobbing or a contact call. In conspecifics, the effect sizes of the response were smaller, suggesting that conspecifics perceive the manipulation as conflicting information. © 2011 The Association for the Study of Animal Behaviour.

This contribution presents findings from two empirical case studies, which followed a task-based telecollaborative learning format. Participants included student teacher trainees, tutors, 1 and language learners from colleges/universities in Germany, Poland, the United Kingdom, and the United States. The projects aimed at promoting learner autonomy through awareness raising of modes and meaning-making online and multiliteracy skills development based on hands-on analysis of web resources and social networking tools. It was hoped that this awareness would foster the teachers' own autonomy in virtual learning environments and enable them to design tasks which-in turn-would promote learner autonomy as understood by Palfreyman: the informed use of a range of interacting resources in context (2006). We argue that this awareness is reflected in enhanced multimodal communicative competence, ?the ability to understand the combined potential of various modes for making meaning? (Royce, 2002, p. 92), and multiliteracy, with the latter allowing teachers and learners to realize the potential of blended and online only settings for language acquisition purposes. Ideally then, while becoming gradually more versed in multimodality and multiliteracy, learners can also take over more control and self-direct their own learning when working online (Benson, 2001) which are also characteristics of autonomy. © 2012.

Birds of a wide range of species show characteristic movements of their tail, often called tail flicking, tail wagging or tail flashing. Tail flicking refers to vertical up-and-down movements of the tail, while tail flashing is defined as a horizontal movement, often including tail spreading. Here, I review proposed functions of such behaviour. Most relate to communication with conspecifics, predators or prey. Tail flashing may induce movement of the bird’s prey that makes the prey more vulnerable to capture (‘prey-flushing’). Tail movements may signal to a predator that the signaller has detected it (‘perception advertisement’), or that the signaller is particularly alert or otherwise difficult to catch (‘quality advertisement’). Further, it may warn conspecifics of predators (‘alarm signal’), or it may advertise quality as a mate, signal social status, or aid in flock cohesion. This behaviour may, possibly, though it seems unlikely, represent a cue rather than a signal in that it benefits the receiver, but not the signaller. For each postulated function, I develop predictions stemming from that function, and interpret the available empirical evidence in the context of these predictions. I finish by synthesising our current state of knowledge and by identifying the future empirical studies that would most improve our understanding of this widespread but unjustly neglected avian behaviour. © The Ornithological Society of Japan 2016.

The insular endemic Cyprus Wheatear Oenanthe cypriaca has been considered as a subspecies of Pied Wheatear O. pleschanka. However, due to several differences in behaviour, habitat selection and morphology, it is currently treated by most authors as an independent species. Here, we used mitochondrial nucleotide sequences of the cytochrome oxidase subunit 1 gene (679 base pairs), playback experiments and dummy presentations to assess the status of O. cypriaca. For the playback experiments we used the conspecific song, and heterospecific songs of the two subspecies of Black-eared Wheatear O. hispanica hispanica and O. hispanicamelanoleuca, O. pleschanka, and Finsch's Wheatear O. finschii. Experimental dummy presentations included O. cypriaca, O. pleschanka and a dark and light morph of O. h. melanoleuca. O. cypriaca responded significantly stronger towards the conspecific model and towards conspecific playbacks than towards heterospecific stimuli. ML and BI analyses support the close relationship between O. cypriaca, O. pleschanka and O. h. melanoleuca. With a relative high posterior probability value (0.98), O. cypriaca clusters closer to O.h. melanoleuca from Iran and Israel (on migration) and O. pleschanka from Iran than to O. pleschanka obtained from Kazakhstan, Russia, Mongolia and wintering areas in East Africa (Kenya). The scenario suggests that O. cypriaca might be either a relatively young taxon, which is yet behavioural distinct, but genetically still similar to its sister populations on the mainland. Alternatively, we may assume a close relationship as an indication for potential ongoing hybridisation processes involving all three forms. © 2011 Dt. Ornithologen-Gesellschaft e.V.

During their staging at stopover sites, migrants compete with resident species over food resources. This 'resource competition hypothesis' has often been examined in breeding areas of songbirds, but little is known about resource competition between migrants and resident species at stopover sites. We studied foraging behaviour and microhabitat of the endemic resident species Cyprus Wheatear Oenanthe cypriaca in comparison to eleven migrating species of the same genus or of the same flycatching guild during spring migration on Cyprus, a Mediterranean stopover site. We characterized microhabitats of congeneric Oenanthe species by less cover overhead and low perches and distinguished them from migrating Ficedula hypoleuca, Ficedula albicollis and Phoenicurus phoenicurus, which preferred high cover overhead and medium perches. In a hierarchical cluster analysis, O. cypriaca clustered together with three shrike species Lanius and the flycatcher Muscicapa striata, with less cover overhead, but high perches. During foraging, hopping behaviour discriminated best among the Oenanthe species. Multidimensional scaling on foraging behaviour showed that O. cypriaca is clearly distinct from the other species. Direct competition (aggressive encounters) between the resident species and migrants was rarely observed. Our results provide support for niche partitioning and coexistence between migrants and a resident species at a stopover site. © 2015 Institute of Zoology, Slovak Academy of Sciences.


The foraging behaviour of the passage migrant Spotted Flycatcher, Muscicapa striata (Pallas, 1764), was compared with the breeding migrant Cyprus Wheatear, Oenanthe cypriaca (Homeyer, 1884), in Cyprus during May 2009. M. striata preferred higher perches, had shorter distances to the next perch, made more aerial sallying per minute and less perch-pounce foraging, and showed a higher overall foraging rate per minute. Based on a principal component analysis, M. striata was characterised by high perches and exclusively aerial foraging, while O. cypriaca was characterised by perch-pounce foraging and larger distances to the next perch. Despite some niche overlap, both species differed in some aspects. Six direct encounters between O. cypriaca and M. striata have been observed, and O. cypriaca was always the winner. M. striata showed a higher foraging speed which is in line with observations in resident-migrant bird assemblages in Africa, where migrants also often had a higher foraging speed. By contrast, the breeding species O. cypriaca was more flexible in its foraging strategies. © Kasparek Verlag.

Niche partitioning has been examined in breeding bird communities and in winter quarters, but has received less attention when comparing a resident breeder and migrants during spring. Here, such an assemblage of species of the same genus (Oenanthe) and guild were analysed on the Mediterranean island of Cyprus. Northern Wheatear O. oenanthe and Eastern Black-Eared Wheatear O. hispanica melanoleuca were migrants, while Cyprus Wheatear O. cypriaca was resident. Migrant wheatears were more common in open habitats without trees, with a lower proportion of vegetation in the 10 cm layer, less tree and bush cover, a higher proportion of herbaceous layer, and a higher amount of bare areas. By using a discriminant function, we found that O. oenanthe was least tolerant towards a high proportion of bush/tree cover, and O. cypriaca was most tolerant, with O. h. melanoleuca in between. Also, O. oenanthe tolerated the least proportion of vegetation in the lowest layer, and O. h. melanoleuca the highest. O. oenanthe hunted more often by hop-and-peck and O. cypriaca more often used sallying and perch-and-pounce. O. oenanthe was the most ground-dwelling species with low perch heights and highest number of hops per minute and hops per movement, while O. cypriaca was the most arboreal species with the highest perches. Mean foraging rate did not differ between the species. A principal component analysis followed by a discriminant function showed that O. cypriaca has a high amount of aerial sallying and perch-pounce hunting behaviour with fewer hops, while O. oenanthe represents the contrary with hop-and-peck movements on the ground and with fewer flights. The data further indicate a clearer separation between O. oenanthe and O. cypriaca while O. h. melanoleuca lies in between utilising both foraging modes. © Dt. Ornithologen-Gesellschaft e.V. 2009.

Fish stocking constitutes a widespread management tool for freshwater fisheries, but depending on configuration can be economically wasteful, ecologically harmful and lead to irreversible biodiversity loss. We conducted a large-scale controlled experiment of a lecture intervention to understand whether communication of neutrally worded scientific information about sustainable fish stocking might alter anglers' ecological knowledge and cognitions (e.g. functional beliefs and attitudes) about the benefits and potential costs of fish stocking. Seventeen angler clubs from Germany who engage in self-organized fish stocking were randomly assigned to receive either a stocking lecture or a control lecture (on general fish management). From each club, self-selected anglers including water-body managers (N = 201) completed a questionnaire on ecological knowledge and cognitions about stocking before the lecture, immediately after the lecture and 10 months later to assess long-term retention. Data were analysed using Before-After-Control-Impact analysis with club-level random effects. Compared to the control group (n = 86), anglers in the treatment (n = 115) showed a significant post-lecture increase in knowledge in all six topics taught about the biological nuances of stocking and potential risks. However, there were no changes in stocking-related attitudes or personal norms towards future stocking. Only one knowledge domain was retained long-term (10 months): the understanding that stocking does not always have additive fishery effects (P < 0·05). There were also trends indicating long-term knowledge gains related to the genetic risks of stocking and the advantages of local adaptation, and a decreased functional belief in stocking efficacy (P < 0·08). These results suggest that participants may engage more cautiously in fish stocking in the future. Synthesis and applications. Lectures will continue to be a dominant mode of environmental education due to convenience and familiarity, particularly for stakeholders participating during leisure time and in contexts where training lectures are legally required. Our results show that lectures can effectively communicate complex ecological topics and lead to knowledge gain. Lectures on natural resource management will be most effective when addressing issues of high relevance to stakeholder's interests and modifying current practices, but changes in basic cognitions may require a more active learning environment. © 2016 British Ecological Society.

Crop mapping is one major component of agricultural resource monitoring using remote sensing. Yield or water demand modeling requires that both, the total surface that is cultivated and the accurate distribution of crops, respectively is known. Map quality is crucial and influences the model outputs. Although the use of multi-spectral time series data in crop mapping has been acknowledged, the potentially high dimensionality of the input data remains an issue. In this study Support Vector Machines (SVM) are used for crop classification in irrigated landscapes at the object-level. Input to the classifications is 71 multi-seasonal spectral and geostatistical features computed from RapidEye time series. The random forest (RF) feature importance score was used to select a subset of features that achieved optimal accuracies. The relationship between the hard result accuracy and the soft output from the SVM is investigated by employing two measures of uncertainty, the maximum a posteriori probability and the alpha quadratic entropy. Specifically the effect of feature selection on map uncertainty is investigated by looking at the soft outputs of the SVM, in addition to classical accuracy metrics. Overall the SVMs applied to the reduced feature subspaces that were composed of the most informative multi-seasonal features led to a clear increase in classification accuracy up to 4.3%, and to a significant decline in thematic uncertainty. SVM was shown to be affected by feature space size and could benefit from RF-based feature selection. Uncertainty measures from SVM are an informative source of information on the spatial distribution of error in the crop maps. © 2013 International Society for Photogrammetry and Remote Sensing, Inc.

The Morningness-Eveningness Questionnaire (MEQ) is the most widely known questionnaire to assess circadian preference. In the present study, the reduced MEQ (rMEQ), a short five-item version of the MEQ, is adapted to German language. A total of 594 participants filled in the German rMEQ and the Composite Scale of Morningness to measure convergent validity. Mean rMEQ scores were 13.97 ± 3.44 and ranged from 5 to 24. Cronbach's α was 0.723 for the total sample and 0.722 in men and 0.701 in women. Cutoff scores showed 126 (21.2%) morning types, 385 (64.8%) neither types, and 83 (14.0%) morning types. A principal component analysis with varimax rotation revealed a single-factor solution. The correlation between the Composite Scale of Morningness and the rMEQ was 0.885. Based on the type classification, there was a good agreement (Cramer coefficient = 0.622). The data presented here show that the rMEQ is also a reliable tool in its German adaptation, but the cutoff scores should be refined and discussed in further work. © 2013 Copyright Taylor and Francis Group, LLC.

Material and method: Language abilities of 46 late talkers (LT) and 40 non-late talkers (NLT) were examined within the framework of a longitudinal study. At the age of 4½ years language skills were evaluated with standardized language tests and analyses of narrative samples. Furthermore, phonological abilities and precursors of written language were assessed.Background: The clinical relevance of early language delay is a controversial issue. The primary objectives of this study were to describe the further language development of German speaking late talkers up to the age of 4½ years and to determine the prevalence of persisting speech-language disorders.Results: At the age of 4½ years the language abilities of LT were significantly below the level of NLT in all language dimensions. Of the LT 43 % had language disabilities, 41 % phonological disabilities and 37 % had received a speech-language therapy; however, some NLT also had mild language and/or phonological problems.Conclusion: These findings suggest that late emergence of language is an indication of low language competence and a risk for persistent language disturbances; therefore, early identification and early intervention are recommended. Nevertheless, more than 50 % of LT have no persistent language disabilities; therefore, a cost-intensive intervention is not justified. Under consideration of efficacy and efficiency a parent-directed training in small groups is advisable to provide a more stimulating environment. © 2015, Springer-Verlag Berlin Heidelberg.

Cities in developing countries are experiencing an unprecedented population growth that illustrates a demographic transition and a shift towards modernization with consequences on their epidemiological profiles. However, this change is characterized by an important rural-to-urban social and cultural transfer that can bias the expected epidemiological transition; at the same time, this transfer renders the understanding of the occurrence of communicable diseases more complex than it appears. Urban malaria occurrence was modeled for the city of Yaoundé in Cameroon. Retrospective interviews were conducted to describe a variety of epidemiological, social and environmental variables at the household level. Various ecological variables originating from remote sensing data were also integrated. Multivariate multilevel negative binomial analyses were developed to evaluate the distinct contributions of explanatory social and ecological variables. Spatial models based on the level of urbanity were implemented to understand the intelligence of urban malaria as characterized by those variables. The results showed an overall higher statistical importance of socio-environmental variables, particularly those describing rural origin socio-cultural features in terms of non-conventional housing types and urban agriculture (UA). The spatial patterns of the urban malaria occurrences displayed a complex combination of population density gradients and socio-environmental factors, illustrating the importance of conventional urban features over rural/non-conventional features in reducing the occurrence of urban malaria. © 2014 Elsevier Ltd.

Over the last decade a sharp decline in interest and participation in science has been identified in young people across Europe. Should this continue, the capacity to innovate both in industry and research will suffer in the long term. A critical issue in addressing this problem is providing young people with relevant contexts and practical experience of scientific concepts through classroom science. Therefore, the development of Inquiry Based Science Education (IBSE) and active teaching and learning approaches has never been more important. The Chain Reaction project aims to capitalise on a previously successful approach to delivering IBSE in the UK in an attempt to embed IBSE practice within European schools. The key aim is to equip teacher educators to train teachers across twelve countries in the use of IBSE materials and techniques. Each country will adapt materials and techniques for use in their own country, addressing issues of different curricula and cultures as necessary. This will ensure that each partner will have ownership of resources and classroom techniques suitable for their own situation and contexts, but based around the proven principles of IBSE and based on materials that have already been tried and tested as part of the original Pupil Researcher Initiative (PRI) project. Chain Reaction will also establish a European teachers network, aimed at providing support to teachers, sharing experiences and expertise between teachers and training experts. This will help develop the work of the project through delivery, and will also contribute to sustainability in the longer term. The network will aid dissemination of the project resources and outcomes, while enabling peer support both within each year of the project, and across the project as a whole. This will ensure sharing, reflection and discussions of experiences and approaches. The teacher training, materials and instruction given will be delivered via a cascade approach within schools.

So far there are contradictory findings concerning the degree of negative influence of attention deficit disorders, external or socio-emotional disorders on academic development of a child. Therefore the present epidemiologic study analyses the relationship between clinically relevant problems and academic achievement of fourth graders (measured by recommendation for secondary school: A-level, B-level or C-level). Children (N = 3910) were rated by their parents by anonymised questionnaires (Child Behavior Checklist CBCL) at the end of primary school. Especially in the field of attention deficit, somatic and anxiety/depression disorders, many children were in a clinically relevant range compared to German norm data. It became obvious that future C-level pupils are particularly strong, multiply problem troubled, with constantly higher problems at all subscales. Mainly attention deficit disorders proved to be relevant for academic achievement, but also delinquent behaviour and social problems, which enhance the relative risk of recommendation for B- or C-level considerably. Early applied preventive interventions supporting social and cognitive development seem therefore of central importance for the school career of primary school children. © Vandenhoeck & Ruprecht GmbH & Co. KG, Göttingen 2012.

Research has shown that emotions play a significant role in the learning process and academic achievement. However, the fact that measurement of emotions during or after instruction usually requires written responses on lengthy research instruments has been given as a reason why researchers have tended to avoid research on this topic in classrooms. Consequently, we developed a short Likert-scale instrument which used only three items within the three factors of interest, well-being and boredom to measure adolescent emotions during instruction in science education. We present four different studies in four populations to assess the validity of the scale. In order to determine the reliability and validity of the instrument, it was administered to pupils across a range of grades (grades 6-12) after being taught standardised lessons by 14 teachers in south-western Germany. The data generated were analysed statistically in terms of their reliability and validity. As the three independent factors (interest, well-being and boredom) had been derived from theoretical constructs, confirmatory factor analysis was applied. In a second study based on pupils from different age groups, grades and school subjects, we found different scores according to age and subject, suggesting that the scale is sensitive to these parameters. A third study used two standardised educational programs in zoology and botany for 5 th and 6 th graders to assess the scale's sensitivity towards changes in emotions. Pupils rated the zoological topic as mo-re interesting than the botanical topic, as less boring and they felt better. External validity was determined by correlating the data that was generated using our scale in a fourth study on University students with the data generated by an established measurement of motivation (the shortened German version of the KIM -"Kurzskala zur Intrinsischen Motivation"). The data generated suggest that the three factors cluster satisfactorily and that the instrument, which can be administered with minimum disruption of classroom time, is both reliable and valid. © 2011 IJESE.

The influence of environmental factors, especially of tropical coastal forests, on the damage impact of a tsunami is still discussed controversially in literature. This paper focuses on the assessment of the vulnerability and protective effect of beach forests in case of the Indian Ocean Tsunami event 2004 in Thailand, based on remote sensing and multivariate-statistical methods. With the use of a post classification comparison, we show that the variability of the damage degree on different coastal vegetation types is highly spatial and species dependent. The combinatory evaluation of results from the change detection analysis and data on coastal vegetation structure from a field survey by using multiple regression analysis further proves that beach forests can have a protective effect against tsunami waves, if they satisfy certain vegetation structural conditions. In this context specific vegetation parameters for the vulnerability as well as the protective effect of beach forests are acquired, which mainly determine its vertical and horizontal forest density. A concluding case study finally illustrates how a combination of empirical tsunami hazard assessment and the presented work could be utilized to support local coastal protection in a targeted and efficient way. © 2011 E.

Background: It is well accepted that medical faculty teaching staff require an understanding of educational theory and pedagogical methods for effective medical teaching. The purpose of this study was to evaluate the effectiveness of a 5-day teaching education program. Methods: An open prospective interventional study using quantitative and qualitative instruments was performed, covering all four levels of the Kirkpatrick model: Evaluation of 1) 'Reaction' on a professional and emotional level using standardized questionnaires; 2) 'Learning' applying a multiple choice test; 3) 'Behavior' by self-, peer-, and expert assessment of teaching sessions with semistructured interviews; and 4) 'Results' from student evaluations. Results: Our data indicate the success of the educational intervention at all observed levels. 1) Reaction: The participants showed a high acceptance of the instructional content. 2) Learning: There was a significant increase in knowledge (PB0.001) as deduced from a pre-post multiple-choice questionnaire, which was retained at 6 months (PB0.001). 3) Behavior: Peer-, self-, and expert-assessment indicated a transfer of learning into teaching performance. Semistructured interviews reflected a higher level of professionalism in medical teaching by the participants. 4) Results: Teaching performance ratings improved in students' evaluations. Conclusions: Our results demonstrate the success of a 5-day education program in embedding knowledge and skills to improve performance of medical educators. Thismultimethodological approach, using both qualitative and quantitative measures, may serve as a model to evaluate effectiveness of comparable interventions in other settings. © 2014 Marco Roos et al.

The interest in the systematic study of the circadian typology (CT) is relatively recent and has developed rapidly in the two last decades. All the existing data suggest that this individual difference affects our biological and psychological functioning, not only in health, but also in disease. In the present study, we review the current literature concerning the psychometric properties and validity of CT measures as well as individual, environmental and genetic factors that influence the CT. We present a brief overview of the biological markers that are used to define differences between CT groups (sleepwake cycle, body temperature, cortisol and melatonin), and we assess the implications for CT and adjustment to shiftwork and jet lag. We also review the differences between CT in terms of cognitive abilities, personality traits and the incidence of psychiatric disorders. When necessary, we have emphasized the methodological limitations that exist today and suggested some future avenues of work in order to overcome these. This is a new field of interest to professionals in many different areas (research, labor, academic and clinical), and this review provides a state of the art discussion to allow professionals to integrate chronobiological aspects of human behavior into their daily practice.

This paper discusses challenges and opportunities arising during the development of open educational resources (OERs) to support communicative language teaching (CLT) with interactive whiteboards (IWBs). iTILT1 (interactive Technologies in Language Teaching), a European Lifelong Learning Project, has two main aims: (a) to promote "best practice" or effective CLT teaching with IWBs, and (b) to support continuing professional development among language teachers both in formal training contexts and through informal independent study. Some 40 teachers in seven European countries, working with learners of six foreign languages at various educational and proficiency levels, were trained and followed over one school year in order to collect over 200 video examples of classroom practice. These short (3-minute) class videos were selected collaboratively by teachers and researchers, and supported by learner and teacher commentaries. The main outcome of the project is an open-access website (http://itilt.eu), a searchable repository of training materials (manual, sample materials) and classroom illustrations (video clips, participant comments). This study explores the action research dimension of successive phases of the project from the development of appropriate training materials, data collection in language classrooms, selection of illustrative teaching episodes, and preparation for online presentation for future teacher education. It investigates the influence of research-based training on teacher development and the inclusion of participant perspectives, and explores how this kind of OER can support open practices. The paper also raises issues with respect to "best practice" and user requirements. The paper concludes with "lessons learned" throughout the project, showing both the advantages and drawbacks to this kind of collaboration between teachers and researchers, as well as furnishing suggestions for future OER development. © 2013 Taylor & Francis.

Stress and Health | Year: 2011

We examined the relationship between morningness-eveningness and three dimensions of everyday stressors troubling adolescent pupils aged 13-16 years. Nine hundred and twenty-four pupils in secondary education, grades 8 and 9, completed the Composite Scale of Morningness (covering habitual rise times and bedtimes) and three-item sets of problem perception in adolescents, namely school-related, parent-related and self-related problem perception. Bad school marks, eveningness orientation and type of school are associated with school-related and parent-related problems when controlling for age and gender. Girls reported more self-related problems than boys. Given that school marks and chronotype were the most important moderators of problem perception, the results indicate that later school start times or adolescents changing their late bedtime behaviour, induced by an educational programme, could reduce the adolescents' stress perception and improve their academic performance.

Life satisfaction is a crucial component of well being, thus research of its determinants are of great importance and are conducted worldwide. Recently, morningness has been shown to be related to greater life satisfaction in Polish and German samples; and in the present study, this relationship was tested in a Spanish adult sample. The results provide further evidence for the relationship of morningness with higher life satisfaction, which it seems independent of culture and geographic location. © 2013 Informa Healthcare USA, Inc.

The human sleep-wake cycle is characterized by significant individual differences. Those differences in the sleep-wake cycle are partially heritable but are also influenced by environmental factors like the lightdark cycle or social habits. In this study we analyse for the first time the sleep-wake rhythm of adolescent pupils and working adolescents in a less industrialised country in West Africa near the equator. The aim of this study was to explore the sleep wake cycle in this geographical region, using Côte d'Ivoire as an example. Data collection took place between 2nd of March and 10th of June 2009. 588 adolescents (338 girls, 250 boys) between 10 and 15 years (mean±SD: 12.72±1.63) participated in this study. We collected data on the religion of the participants (Christian (N159), Muslim (N352), otherno religion (N77)) and their occupation. Participants were either pupils attending school (N336) or adolescents that were already working (N252) and not attending school. The interviewer filled in the questionnaire. We found significant effects of age (p<0.001), gender (p<0.001), occupation (p0.002), religion (p<0.001) and region (p<0.001). The midpoint of sleep was on average 1:26 (SD: 00:30) on weekdays and 1:37 (SD: 00:42) on weekend days. There are significant differences between weekdays and weekend days, but these were only small. Sleep duration suggests that adolescents in Côte d'Ivoire may gain sufficient sleep during week and weekend days, and thus, may live more in accordance with their own biological clock than adolescents in the northern hemisphere. In contrast, the data can be interpreted that adolescents live in a permanent 'jetlag'. Factors may be the more continuous lightdark cycle in the tropics, low amount of ambient light and less electricity. Copyright © Informa Healthcare USA, Inc.

Men sleep shorter and go to bed and get up later than women, thus they are later chronotypes. This difference between the sexes is most pronounced between puberty and menopause indicating the possibility that morningness is subject to sexual dimorphism related to reproductive aspects. The objective of the study was to compare the sleep-wake behavior of women with their actual partners and with their preferred partners. As a hypothesis, we expect some assortment in mating concerning chronotype (with the actual partner), but we also expect a higher synchronization with a preferred ideal partner. 167 women were analyzed in this study (mean age: 23.0 ± 2.57 (SD) years). Mated women were earlier chronotypes than their partners (t = -2.051, p =.042, d =.34) but the difference was small (11:02 min ± 1:04 min). The results of the present study showed women preferring a partner synchronized to their own sleep-wake-rhythm more than their actual partners were. The above result was true either for single facets of the sleep-wake rhythm (e.g. bed time, sleep onset) or for midpoint of sleep on free days - an indicator of actual chronotype: women's and their partners' correlation of midpoint of sleep was lower (r =.513) than women's and their ideal partners' correlation (r =.855). Amongst various sleep-wake measures, women particularly preferred a partner going to bed at the same time. Assortative mating according to sleep-wake rhythm exists, but women for long-term pair-bonds would like their partners far more synchronized.

Background: Alongside improvements in hearing and communication skills, the rehabilitation of children, adolescents and adults with a cochlear implant (CI) in recent years has increasingly taken into account mental health and quality of life issues. In the context of the programs offered, this study assesses the significance of dance for the mental health of adult clients with a CI. Methods: Eleven adult CI users participated in a dance project, which took place as a cooperation between the ENT University Hospital Heidelberg and the Baden State Theatre Karlsruhe. Participants were questioned at two different time points for assessment with the mental health scales (SPG). These scales measure seven different aspects of psychosocial well-being (including autonomy, willpower, affirmation of life and meaningfulness). Results: Significant positive changes in the domains of affirmation of life, self-reflection and social integration were revealed by before and after comparisons; tendencies toward positive change were observed (p ≤ 0.10) in the domains of willpower, naturalness and meaningfulness. No changes were observed in the autonomy domain. Conclusion: The results indicate that the mental health of adult clients with a CI can be strengthened by dance as a complementary rehabilitation module. Concepts of CI rehabilitation should increasingly find anchor in the consideration of such arrangements for its range of offers. © 2014 Springer-Verlag Berlin Heidelberg.

Previous findings have demonstrated that chronotype (morningness/intermediate/eveningness) is correlated with cognitive functions, that is, people show higher mental performance when they do a test at their preferred time of day. Empirical studies found a relationship between morningness and higher learning achievement at school and university. However, only a few of them controlled for other moderating and mediating variables. In this study, we included chronotype, gender, conscientiousness and test anxiety in a structural equation model (SEM) with grade point average (GPA) as academic achievement outcome. Participants were 158 high school students and results revealed that boys and girls differed in GPA and test anxiety significantly, with girls reporting better grades and higher test anxiety. Moreover, there was a positive correlation between conscientiousness and GPA (r = 0.17) and morningness (r = 0.29), respectively, and a negative correlation between conscientiousness and test anxiety (r = -0.22). The SEM demonstrated that gender was the strongest predictor of academic achievement. Lower test anxiety predicted higher GPA in girls but not in boys. Additionally, chronotype as moderator revealed a significant association between gender and GPA for evening types and intermediate types, while intermediate types showed a significant relationship between test anxiety and GPA. Our results suggest that gender is an essential predictor of academic achievement even stronger than low or absent test anxiety. Future studies are needed to explore how gender and chronotype act together in a longitudinal panel design and how chronotype is mediated by conscientiousness in the prediction of academic achievement. © 2016 Taylor & Francis.

Age-related macular degeneration (AMD) - despite advances in prevention and medical treatment options - remains prevalent among older adults, often resulting in functional losses that negatively affect the mental health of older adults. In particular, the prevalence of both anxiety and depression in patients with AMD is high. Along with medical treatment options, low vision rehabilitation and AMD-specific behavioral and self-management programs have been developed and have demonstrated effectiveness in improving the mental health of AMD patients. This article reviews the prevalence of anxiety and depression in patients with advanced AMD, discusses potential mechanisms accounting for the development of depression and anxiety in AMD patients, presents the state-of the-art of available interventions for addressing anxiety and depression in AMD patients, and delineates recommendations for eye care professionals regarding how to screen for these two prevalent mental health problems and how to facilitate appropriate treatment for patients with AMD. © 2016 Cimarolli et al.
