Renewable Energy | Year: 2014
The present study investigates renewable energy analyzing the last twenty years of worldwide scientific production and the dynamics of interest around relevant policies in this direction. Based on a review on the role of knowledge development in technology transitions, we coupled bibliometric and expert debate approaches to provide decision makers with a sound analysis of thematic and regional trends in the field. Results show that the level of activity of researchers in the field of solar energy is somewhat contrasted only by biomass and wind energy. Despite countries being embedded in a global virtual network, geographical differences still arise: while North America and Europe show isomorphism of national communities and a high diversification of vertical foci, emerging research communities (e.g. BRICS countries) reflect market strategies (e.g. China) and the natural environment (e.g. Brazil) with a higher directionality of researches.Our findings provide an overall picture on world-wide development of competences as a relevant variable which policy makers should ideally consider in detail when setting integrated research, industrial and energy policies and strategies. © 2013 Elsevier Ltd.

Workplace bullying has been a topic of increasing interest since the 90s. Several studies have contributed to a better understanding of the antecedents and consequences of being exposed to negative acts at work during a prolonged period of time. However, there is a lack of validated instruments in Italian to map workplace bullying. Consequently, the goal of the present study is twofold. First, the authors aim to validate the Italian version of the Negative Acts Questionnaire-Revised (NAQ-R: Einarsen and Hoel, 2001; Einarsen, et al., 2009). Second, the authors aim to establish the prevalence of workplace bullying. Results from 3,112 employees nested within 25 Italian organizations revealed that a reduced version of 17 items with a two-factor structure provided the best fit. Moreover, the prevalence of bullying was 15.2 per cent according to the criteria proposed by Mikkelsen and Einarsen (2001). Furthermore, significant correlations between bullying dimensions and organizational climate were found, which provided additional support for using the NAQ-Italian reduced version. Implications to prevent bullying and improve employees' well-being using this method are discussed. © 2011 by National Institute of Occupational Safety and Health.

To provide a comprehensive picture of the whole spectrum of psychosocial factors potentially associated with adolescent cannabis use, bivariate and multivariate analyses were used to assess a variety of social, demographic, psychological, and behavioral correlates of last-month cannabis use and age of first use among 6,838 students. Results showed that only family problems, alcohol and/or other drug use/misuse, deviant behavior, and victimization were independently associated with either recent cannabis use or early onset of cannabis use when multiple, interacting factors were considered. Certain family and behavioral factors might be more important than other psychosocial correlates of adolescent cannabis use. Copyright © Taylor & Francis Group, LLC.

Objective: The Food Craving Questionnaire-Trait (FCQ-T) is commonly used to assess habitual food cravings among individuals. Previous studies have shown that a brief version of this instrument (FCQT- r) has good reliability and validity. This article is the first to use Confirmatory factor analysis to examine the psychometric properties of the FCQ-T-r in a cross-validation study. Method: Habitual food cravings, as well as emotion regulation strategies, affective states and disordered eating behaviors, were investigated in two independent samples of non-clinical adult volunteers (Sample 1: N = 368; Sample 2: N = 246). Confirmatory factor analyses were conducted to simultaneously test model fit statistics and dimensionality of the instrument. FCQ-T-r reliability was assessed by computing the composite reliability coefficient. Results: Analysis supported the unidimensional structure of the scale and fit indices were acceptable for both samples. The FCQ-T-r showed excellent reliability and moderate to high correlations with negative affect and disordered eating. Conclusions: Our results indicate that the FCQ-T-r scores can be reliably used to assess habitual cravings in an Italian non-clinical sample of adults. The robustness of these results is tested by a crossvalidation of the model using two independent samples. Further research is required to expand on these findings, particularly in children and adolescents. © 2015 Iani.

The macroeconomic context and crisis management are now becoming salient issues among employees. Low levels of fear about the economic situation and the belief that one is capable of obtaining new employment may enable individuals to maintain mental health and job satisfaction in austere times. The aim of the present study is to investigate the relationship of fear of the economic crisis and nonemployability with job satisfaction and psychological distress, while controlling for demographics factors, stress exposures, and high conflict perceptions. This cross-sectional study was conducted in 3 Italian organizations comprising 679 workers with a response rate of more than 60%. Hierarchical regression analysis showed that, after controlling for demographics, psychological demands, lack of job control, and workplace bullying, low perceived employability and fear of the economic crisis were positively associated with psychological distress and negatively associated with job satisfaction. As an emerging topic of study, it appears that economic stress is an important construct in the nomological network for studying organizational health. The present study complements existing stress theories by suggesting that features of the external environment are relevant and important determinants of psychological distress and job dissatisfaction. © 2015 American Psychological Association.

The first part of this paper describes the flow of tourism on a national and international scale, emphasizing the role that entertainment tourism and theme parks play globally. Following these preliminary remarks, the second part of the paper presents the positive and negative economic effects of leisure tourism opportunities at the European and regional level. The third part of the paper analyses the environmental aspects of tourism and entertainment tourism. It shows that sustainable tourism development can be an essential condition for the protection of natural and cultural resources. Finally, the fourth part summarizes some of the most important social issues arising from tourism activities, among them the conflict between residents and tourists on the exploitation of resources and the demonstration effect deriving from the consumption of resources. To avoid this spoliation and destruction of the destination (land and local community), the paper suggests a new Humanism based on Catholicism as a way to realize a sustainability utopia. © 2016 University of Warsaw - Faculty of Geography and Regional Studies.

Universities have long been involved in knowledge transfer activities and are increasing their efforts to collaborate with industry. However, universities vary enormously in the extent to which they promote, and succeed in commercializing, academic research. In this paper, we focus on the concept of cognitive distance, intended as differences in the sets of basic values, norms and mental models in universities and firms. We assess the impact of cognitive distance on university-industry collaborations. Based on original data from interviews with 197 university departments in Italy, our analysis determines whether cognitive distance is perceived as a barrier to university-industry interactions, and estimates its effects on the frequency of their collaborations. Our results confirm that cognitive, albeit not affecting the probability of departments to collaborate with firms, significantly hinders the frequency of interactions. © 2012 Springer Science+Business Media, LLC.

Background: The Hospital Anxiety and Depression Scale (HADS) is a widely used self-report measure to assess emotional distress in clinical populations. As highlighted in recent review studies, the latent structure of the HADS is still an issue. The aim of this study was to analyze the factorial structure of the HADS in a large community sample in Italy, and to test the invariance of the best fitting model across age and gender groups. Methods: Data analyses were carried out on a sample of 1.599 participants proportionally stratified according to the Italian census population pyramid. Participants aged 18 to 85 years (females = 51.8%), living in eight different regions of Italy, voluntarily participated in the study. The survey questionnaire contained the HADS, Health Status questions, and sociodemographic variables. Results: Confirmatory factor analysis indicated that a bifactor model, with a general psychological distress factor and two orthogonal group factors with anxiety and depression, was the best fitting one compared to six alternative factor structures reported in the literature, with overall good fit indices [Non-normed Fit Index (NNFI) = .97; Comparative Fit Index (CFI) = .98; Root Mean-Square Error of Approximation (RMSEA) = .04]. Multi-group analyses supported total invariance of the HADS measurement model for males and females, and for younger (i.e., 18-44 years old) and older (i.e., 45-85 years old) participants. Our descriptive analyses showed that females reported significant higher anxiety and general distress mean scores than males. Moreover, older participants reported significant higher HADS, anxiety and depression scores than younger participants. Conclusions: The results of the present study confirmed that the HADS has good psychometric properties in an Italian community sample, and that the HADS scores, especially the general psychological distress one, can be reliably used for assessing age and gender differences. In keeping with the most recent factorial studies, our analysis supported the superior fit of a bifactor model. However, the high factor loadings on the general factor also recommend caution in the use of the two subscales as independent measures. © 2014 Iani et al.; licensee BioMed Central Ltd.

This paper analyzes the implications of incomplete information for the conduct of monetary policy in small-open economy. I use a standard theoretical DSGE model to evaluate the performance of simple rules, including the exchange rate peg. Incomplete information is modeled assuming that the central bank and the private sector observe domestic inflation and output with a measurement error, while they do not observe potential output. I show that not reacting to the exchange rate yields better outcomes in terms of a standard loss function. For the case of complete information and incomplete information, I quantify for which parameter configuration a Taylor rule reacting to both the exchange rate and the domestic inflation rate yields a higher loss than the fixed exchange rate regime. © 2016 Springer Science+Business Media New York

For about a century clinical observations suggested the association between dissociative symptoms and developmental trauma. Retrospective and prospective studies confirmed that dissociation is the central pathogenic process of developmental trauma. dissociative processes generate dissociative symptoms likely to dominate some clinical pictures such as dissociative disorders or Borderline personality disorder, or also surface, in different proportions, in practically all dsm-iv diagnostic categories as an index of negative outcome. this paper aims to review some crucial issues on dissociative phenomena and processes originated from traumatic experiences in childhood. the article also purposes the existence of a traumatic-dissociative psychopathological dimension, its clinical meaning and the treatment strategies to overcome the difficulties it causes during psychotherapy. © 2013 giovanni Fioriti editore s.r.l.
