This study investigates with the help of a manipulative experiment how people with different nationalities perceive meadow-like arrays of different species richness (1, 8, 16, 32, 64 species). Participants (n = 187) were all residents of the canton of Zurich and originated from 43 different countries. Overall valuation of the meadow-like arrays increased with species richness. However, while participants from high-income countries (measured by GDP per capita) clearly liked species-rich meadows most and species-poor ones least, participants from low-income countries did not have such clear preferences. Preferences were not related to the length of time a participant had already spent in Switzerland (on average seven years), but to perceived familiarity with a meadow-like array. Sex and education did not influence valuations. Environmental expertise fostered participants’ dislike of species-poor arrays, as did age. © 2017 Landscape Research Group Ltd

Closing the Gender Gap in Parenting-The (Dwindling) Difference Between Men and Women Parents: Ideal, Taboo, Stress Factor Equally shared parenting is an important ideal to many parents today. It developed in the late 20th century, but a brief look at social history tells us that its roots extend a long way back and are closely aligned with the European path in the development of family structures particularly due to the manorial system and western Christian religion. The operative factors include the increasing significance of matriline-al descent, consensus and partnership, parents as a dual work and leadership unit of the manorial household, the emergence of the collective term »par-enthood«, European biographical patterns, spiritual kinship, the secular deification of the child, and changes in gender order of the economic systems. Parenthood, therefore, is by no means a merely »private« matter of individual parents, but a matter of the whole society. In the century-long evolution of its generativity, every society molds parenthood as an indispensable basic process.

The textbook Discovering Ethics with Philo is intended to help primary school children to learn how to philosophize. The didactical foundation is derived from Matthew Lipman's community of inquiry, as well as Ekkehard Martens's Five-Finger Model. The latter encompasses five philosophical methods-phenomenology, hermeneutics, analytic/logic, dialectics, and speculation-that are integrated into a whole, or metaphorically, the hand. In this article, I present the main chapter of the textbook used for Grades 1-2 that describes the five philosophical methods, as well as one example unit of the textbook used for Grades 3-4 on the topic of "my model role-your model role." © Regents of the University of California on behalf of the Laboratory of Comparative Human Cognition.

Purpose: The aim of this study was to analyze the association between adolescent and familial health behavioral factors and cardiorespiratory fitness in German adolescent boys and girls. Methods: This study is based on a large nationwide cross-sectional study and its substudy on physical activity and fitness of children and adolescents ("Motorik-Modul"). For 1,328 adolescents between 11 and 17 years of age, data on cardiorespiratory fitness (Physical working capacity 170, PWC170) and familial and adolescent health behavioral factors were collected. Health behavior was assessed using psychometric questionnaires (socioeconomic status, pubertal stage, daily physical activity, sports-club time, parental physical activity habits, etc.). A hierarchical multiple regression model was used to quantify the association between relative PWC170 values and health behavior. Results: The relationship between adolescents' health behavioral factors and cardiorespiratory fitness was stronger than the relationship between age, social status, familial health behavior and cardiorespiratory fitness. Familial health behavioral factors explained 4.1% and 2.1% of variance in cardiorespiratory fitness in girls and boys, respectively. Adolescents' health behavioral factors explained 15.2% of variance in girls and 25.7% of variance in boys. For both girls (β =.273) and boys (β =.400), being normal weight had the greatest effect on relative PWC170 values. Conclusions: The difference in explained variance in cardiorespiratory fitness by familial and adolescents' health behavioral factors between girls and boys indicates that different predictors for cardiorespiratory fitness are important for girls and boys. Hence, sex specific research and interventions aimed at improving familial and adolescent health behavior may be important. © 2013 Society for Adolescent Health and Medicine. All rights reserved.

Private gardens can incorporate a diversity of habitats for wild species and also provide a valuable network for meta-populations. Recently, attempts have been made to promote garden practices that increase native biodiversity and structural heterogeneity relevant to plants and animals. However, little is known about whether such practices contribute to the aesthetic quality of gardens. This study was based on a survey of 36 garden owners in Switzerland, a species count in their gardens, and a photo-questionnaire with 249 Swiss residents who rated the attractiveness of the gardens. The gardens included a gradient from conventional orthodox (frequent lawn mowing and weeding, intensive use of pesticides and fertilizers) to ecological unorthodox (infrequent lawn mowing and weeding, no use of pesticides and fertilizers) gardening practices. Our results clearly show that scientific concepts of ecological quality can align with cultural concepts of aesthetic quality. The more ecologically managed a garden, the more species it contained. The more species the garden contained, the more attractive it was to the sample population. Aesthetically pleasing gardens were characterized by the public as natural and species-rich, whereas aesthetically displeasing gardens were characterized as boring, normal, and species-poor. Ecological gardening was not considered to be more time consuming than conventional gardening. A lack of practical know-how was a greater constraint. Respondents were tolerant towards ecological gardening, but would not want their garden to be considered as chaotic. © 2012 Elsevier Ltd.

We tested in two corresponding studies the hypothesis that urban gardening is of visual aesthetic value to the public. With the help of photo-realistic visualizations and a written questionnaire, 109 students and employees of the Karlsruhe University of Education (study 1) and 200 passers-by in the city of Karlsruhe (study 2) were asked about their opinion on different urban gardening scenarios, and attitudes towards urban gardening. Our results indicate that urban gardening can contribute to perceived attractiveness of urban areas, but that not all approaches are perceived as equally positive. While flowerbeds or flower meadows and orderly-managed vegetable plots, in comparison to conventional lawns, increased the aesthetic appeal of urban green space, container gardening approaches, which were often characterized as chaotic, did not. Although flower scenarios were preferred over vegetable scenarios, participants were rather positive about the idea of having more vegetable plots around. Socio-demographic variables had only minor influences on preferences and attitudes. As people were fonder of flowerbeds or flower meadows than of vegetable plots, a mixture of both might be advisable in urban gardening sites. This would also increase overall diversity, which is not only beneficial from an aesthetic, but also from an ecological point of view. © 2016 Elsevier GmbH.

The demand to create learning arrangements In which self-controlled learning is possible becomes increasingly urgent. The established German-language literature on projects names characteristics of self-controlled learning as central components of project-based instruction. Learners, on the other hand, consider themselves less selfcontrolled in project-oriented Instruction and their assessment is confirmed by that of the teachers. Thus, a discrepancy Is revealed between the expectations connected with selfcontrolled learning In project-based Instruction and its evaluation by both teachers and learners.

Zygonyx torridus inhabits waterfalls, rapids and riffle sections. Males patrol over these sites. After copulation the partners perform an extensive search while flying in tandem over a wide range. Behavioural studies in Mauritius 1997 and 2014 showed that there is considerable plasticity in oviposition behaviour. Three main modes could be distinguished: (A) egg-laying in tandem during flight; (B) the female placing the eggs while dipping in flight without physical contact with the male; and (C) the female placing the eggs when settled without physical contact with the male. On several occasions two modes, and in a single case all three types, were observed within one oviposition sequence. In odonates, such a high degree of plasticity in reproductive behaviour was not reported previously. © 2015, Worldwide Dragonfly Association.

From 12 to 25 August 2009, the odonate fauna of Santo Antäo, Cape Verde was surveyed by recording adults and collecting larvae and exuviae at 26 localities, mostly situated in the northwest of the island. Based on the results of this survey and literature data on the Cape Verdes it appears that the resident odonate fauna consists of only five species, namely Anax imperator, Crocothemis erythraea, Orthetrum trinacria, Trithemis annulata and Zygonyx torridus. Three additional species, Anax ephippiger and Pantala flavescens, which were recorded as single adults in this study, and Sympetrum fonscolombii, which was previously recorded in another study, represent seasonal invaders that do not establish permanent populations on the island. Surprisingly, there is no zygopteran species recorded from the island, although a few occur on the neighbouring islands. The breeding habitats of the resident odonates on the island comprise short perennial stream sections in large wadi beds ('ribeiras') that are intensely used for agriculture, as well as artificial irrigation tanks. The odonate assemblage is very uniform, although Z. torridus prefers micro-habitats with flowing water and O. trinacria is found only in micro-habitats with fine sediments. In the absence of fish, crabs and large water beetles, the larva of A. imperator appears to be the top predator in freshwater habitats.
