Urban green areas have become an important tool for biodiversity conservation in cities. However, land use and the different management practices applied to these areas determine their effectiveness as biodiversity refuges within cities. In our study, we compare the biodiversity of three bioindicator groups of arthropods (ants, spiders and harvestmen) found in eleven urban green sites in Warsaw (Poland). The studied sites represent three categories of management: botanical gardens, public parks and urban woodlands. Our aim was to determine the effect of the type of management (as urban green categories) on arthropod communities in urban areas.

Abstract. Stochastic production frontiers are used for estimating regional matching functions where unemployment outflow is ‘produced’ by the unemployed and vacancies. The frontier is estimated using regional panel data from Finland from 1988 to 1997 and the Battese and Coelli frontier model, where the explanatory factors are included in the inefficiency term. The stochastic frontier matching function has constant returns, whereas in OLS estimation with fixed effects the returns are slightly increasing. Unemployment and vacancies in neighbouring regions have a spillover effect on efficiency. Excess job reallocation in a region deteriorates matching efficiency. The decomposition of total factor productivity change in matching to efficiency change and change in matching technology is also investigated by interpreting the matching frontier as a distance function and using Malmquist indexes. There is a downward trend in the technology, but short‐term variations are dominated by cyclical changes in efficiency.  相似文献

This article focuses on the intersections of age, gender and class in interpretations of the aging and situational identity work of middle-aged working-class men. Empirically the article is based on interview data (4 focus groups and 9 personal interviews with 40+ men) in which Finnish paper-mill workers are interviewed about health. Based on the theoretical implications of intersectionality, the article provides an empirical analysis of how age-based cultural hierarchies and distinctions are used flexibly in the process of self-identification and how categorizations of age and conceptualizations of aging are tightly interwoven with gender and class. The analyses show that the middle-aged interviewees base their interpretations of the aging self on negotiating their position between the age categories of the ‘young’ and ‘old’. Both these groups are labeled with rather negative characteristics regarding the irresponsibility for health among the young and impaired functional ability of the old, which conflicts with the working-class expectations regarding masculine identity. The findings suggest that studying how people ‘do age’ requires consideration of the respects in which aging is an age-specific and gendered process shaped by class-based values, ideals and practices.  相似文献

Gender mainstreaming has been celebrated as a new policy strategy for change in gender relations. However, its transformative potential seems to be lost in the process of implementation. The aim of this article is to evaluate the policy effectiveness of gender mainstreaming and its ability to bring about change in gendered social structures and practices. Previous research has focused on gender mainstreaming as a policy strategy. This article provides a new perspective on the problems of implementation by approaching gender mainstreaming from an organizational perspective. Gender mainstreaming takes place in certain organizational contexts, implemented by local actors. This article reveals the practices of implementation in the Finnish state administration, specifically in the Ministry of Defence. The analysis is based on a discursive reading of thirteen group and individual interviews collected in the Ministry of Defence in 2012. The article pinpoints two interlinking problems concerning implementation of gender mainstreaming on the organizational level. First, the state officials, who should implement gender mainstreaming, do not have enough information to do so successfully. Second, there is resistance toward gender mainstreaming on the organizational level. This article suggests that negotiations about gender, gender equality and gender mainstreaming as complex issues concerned with social power relations should be included in the process of implementing gender mainstreaming.  相似文献

Since 2004, the opening of labour markets has spurred a considerable number of Poles to emigrate e.g. to Iceland and England. Families with school age children have had the challenge of adapting to foreign environments and school systems. Polish complementary schools have played an important, albeit ambivalent, role in this process. Through focus group interviews with students in Polish complementary schools in one city in Iceland and one city in England, we gathered information showing common threads between both schools as well as differences in their structure, role, origin and the student motivation to participate. Saturday schools abroad are considered to be less demanding by students than regular schools back in Poland, but more so than regular Icelandic/English schools, which many rate as unsatisfactory in terms of their academic development. The tension between the need for freedom and high expectations for the academic outcome of education influences student opinions, not only about schooling, but also about the host society.  相似文献

The authors examined the relations among intimate partner violence (IPV), maternal depressive symptoms, and maternal harsh intrusive parenting. Using a cross‐lagged, autoregressive path model, they sought to clarify the directionality of the relations among these 3 variables over the first 2 years of the child's life. The results indicated that, in this diverse sample of families living in predominantly low‐income rural communities (N = 705), higher levels of early IPV were associated with increases in maternal depressive symptoms, which in turn were associated with increases in maternal harsh intrusive parenting behaviors. These findings suggest that interventions aimed at improving the parenting of women exposed to domestic violence may want to simultaneously target IPV and depressive symptomatology.  相似文献

In this paper we explore how our cultural contexts give rise to different kinds of knowledges of autism and examine how they are articulated, gain currency, and form the basis for policy, practice and political movements. We outline key tensions for the development of critical autism studies as an international, critical abilities approach. Our aim is not to offer a cross-cultural account of autism or to assume a coherence or universality of ‘autism’ as a singular diagnostic category/reality. Rather, we map the ways in which what is experienced and understood as autism, plays out in different cultural contexts, drawing on the notion of ‘epistemic communities’ to explore shifts in knowledge about autism, including concepts such as ‘neurodiversity’, and how these travel through cultural spaces. The paper explores two key epistemic tensions; the dominance of ‘neuro culture’ and dominant constructions of personhood and what it means to be human.  相似文献
