Over the past 20 years, rural areas in Western societies have transformed from a production to a consumption space. Much research on rural diversification and revitalization has focused on farmers and their wives. However, it is useful to examine side activities run by non-farm women which have slowly emerged in the last few years. In view of discussions about rural decline, the value of such activities should be looked at in a new light. Although these activities may not significantly reverse unemployment figures, they have the potential to provide the social and emotional ‘glue’ to motivate a household to remain in declining areas as small-scale economic activities contribute to a better quality of life and a higher level of well-being. In this article we draw on the personal stories of women who undertake side activities in the Veenkoloniën, the Netherlands. We explore the factors that enable these women to start a side activity and the related organizational and emotional struggles they face while running such activities within the perimeter of their home. We further highlight the importance of side activities for the empowerment of women in rural households.  相似文献

Three relations between elementary school children were investigated: networks of general dislike and bullying were related to networks of general like. These were modeled using multivariate cross-sectional (statistical) network models. Exponential random graph models for a sample of 18 classrooms, numbering 393 students, were summarized using meta-analyses. Results showed (balanced) network structures with positive ties between those who were structurally equivalent in the negative network. Moreover, essential structural parameters for the univariate network structure of positive (general like) and negative (general dislike and bullying) tie networks were identified. Different structures emerged in positive and negative networks. The results provide a starting point for further theoretical and (multiplex) empirical research about negative ties and their interplay with positive ties.  相似文献

In competitive swimming, suits have become more important. These suits influence friction, pressure and wave drag. Friction drag is related to the surface properties whereas both pressure and wave drag are greatly influenced by body shape. To find a relationship between the body shape and the drag, the anthropometry of several world class female swimmers wearing different suits was accurately defined using a 3D scanner and traditional measuring methods. The 3D scans delivered more detailed information about the body shape. On the same day the swimmers did performance tests in the water with the tested suits. Afterwards the result of the performance tests and the differences found in body shape was analyzed to determine the deformation caused by a swimsuit and its effect on the swimming performance. Although the amount of data is limited because of the few test subjects, there is an indication that the deformation of the body influences the swimming performance.  相似文献

In this study we examine whether the Work Ability Index (WAI) has additional value in predicting long-term absenteeism in construction industry. Results of the study show that the WAI has additional value in predicting absenteeism, but that the amount of explained variance is low. This is partly due to the definition of absenteeism in The Netherlands, where this study took place.  相似文献

Research on Eastern Europe stresses the weakness of its civil society and the lack of political and social involvement, neglecting the question: What do people themselves think it means to be a good citizen? This study looks at citizens’ definitions of good citizenship in Poland, Slovenia, the Czech Republic and Hungary, using 2002 European Social Survey data. We investigate mean levels of civic mindedness in these countries and perform regression analyses to investigate whether factors traditionally associated with civic and political participation are also correlated with citizenship norms across Eastern Europe. We show that mean levels of civic mindedness differ significantly across the four Eastern European countries. We find some support for theories on civic and political participation when explaining norms of citizenship, but also demonstrate that individual-level characteristics are differently related to citizenship norms across the countries of our study. Hence, our findings show that Eastern Europe is not a monolithic and homogeneous bloc, underscoring the importance of taking the specificities of countries into account.  相似文献

There is growing recognition of urban areas as hosts for innovative ways to conserve and promote biodiversity. Parks, as one specific type of urban green space, constitute particularly important biodiversity hotspots in the cityscape. We reviewed empirical findings on the species richness in urban parks across all species groups that have been studied. The aim was to assess and discuss the overall species richness of urban parks, its community attributes and drivers. Search and subsequent selection process resulted in 62 papers from 25 different countries. For all examined species groups, the findings consistently show that parks are among the most species rich types of urban green spaces, but also that exotics constitute large shares, especially of plant species. Key ecological theories like the gradient approach and the island habitat ecological theory, and fundamental ecological relationships such as the species-area relationship are valid despite the manipulated ‘nature’ of parks and the surrounding urban matrix. Most studies surveyed large number of parks and applied ‘multi-scale’ approaches in tests of confounding variables, providing methodological strength. While matrix effects are consistently found to affect species richness negatively, the diversity of habitats and microhabitat heterogeneity contained in urban parks appears as the most decisive factor for the overall species richness. However, a constraint of research to date is the limitation of individual studies to one or a few species groups, rarely bridging between flora and fauna. Adopting ‘multi-species group’ approaches in future research is needed to further advance the understanding of the overall biodiversity of urban parks, and its drivers.  相似文献

To explore questions in history and to construct historical narratives, historians work with evidence from the past. This approach to teaching history (inquiry involving the use of evidence) is an accepted part of the research on history teaching and is promoted widely in standards frameworks and practitioner publications as “good history instruction.” What happens in a standards-based setting where teachers are covering large bodies of content? Do teachers use sources as part of their daily instruction? If so, how? We were afforded the unique opportunity to spend time observing what 35 teachers do by analyzing 352 videos submitted over a 4-year time span. We observed a spectrum of source use within and across teacher practice. In this article we share what we noticed.  相似文献

Conclusions about temporal changes in age and circumstances of first intercourse are generally derived from retrospective reports by people of various ages in cross-sectional studies, with an inherent assumption of no bias stemming from time since the event. We examined this assumption through repeated questions on age and circumstances of first heterosexual intercourse (FHI) at ages 21 and 38 in a birth cohort. Despite considerable movement in individual reports, there was no bias in reported age of FHI. However, a greater proportion of both men and women stated at the later assessment both partners had been equally willing (versus persuading or persuaded). The distribution of current views of the appropriateness of the timing did not differ markedly between assessments, although there were many individual changes. Reports of contraceptive usage were similar at the two assessments for men but differed among women, mainly through more reporting that they could not remember. These findings imply that among cohorts born in the 1970s, there is no bias in reports of age of FHI many years after the event, and views on the appropriateness of timing persist. However, time biases reports in favor of a more mutual willingness.  相似文献

This article links the development of service user involvement championed in the United Kingdom to two examples in Dutch-speaking qualifying social work programmes: one from Belgium and one from the Netherlands. In both projects, a longer lasting cooperation with more marginalised service users was established. The Belgium project highlights social work lecturers and service users living in poverty, working in tandem to deliver a module to social work and socio-educational care work students. The example from the Netherlands involves young people from a homeless shelter as peer-researchers, working together with social work students.

Both projects, one focusing on social work education and on social work research, highlight striking similarities in the positives and challenges of working with service users including how this challenges both groups preconceptions of the other, deepens learning but also creates greater potential for confrontations which need to be managed creatively. The article also identifies the pre-requisites for this to be effective including appropriate resourcing, training, facilitative skills and acknowledges that collaborations can be extremely fragile. However, such projects need further investment, experimentation and implementation on an international scale to share learning and promote creative approaches for the development and learning of social work students.  相似文献
