Urbanisation is an expansive process and a majority of insects live in human-modified areas. At the same time, a decrease in pollinator species richness and abundance has recently been observed in Europe, which in turn may have serious ecological and economic consequences. This study investigates the abundance, species richness and functional traits of wild bees in urban city parks in comparison to natural areas. The aim of this research was to assess the potential conservation values of urban green areas for bees. The present study demonstrates that a large and diversified city park may be a favourable habitat for bees, comparable to the natural fauna both in terms of the number and abundance of bee species. However, the study also showed that there were differences in the occurrence of species with different functional traits in the city parks investigated and in the natural landscape.  相似文献

This study examined secular trends in Russian adolescent mental health, the specific effects of the COVID-19 pandemic, and associations with country-level indicators. A cross-sectional survey of 12,882 adolescents aged 11–18 years was carried out between 1999 and 2021 using the Strengths and Difficulties Questionnaire. The results showed an incline in girls' internalizing problems with a two-fold increase in the gender gap. There was a decline in girls' prosocial behavior and an incline in peer problems, with decreasing gender differences. Conduct problems showed a reversal of gender differences. Changes during the pandemic were not greater than over-time changes, with the exception of inclines in hyperactivity-inattention in both genders. Time trends in adolescent mental health were associated with over-time changes in national indicators of wealth and gender equality. The findings provide a strong basis for further research into the determinants of gender differences in adolescent mental health and for gender-specific interventions.  相似文献

Drawing on interviews with 40 Polish migrants in the UK, ethnographic and autobiographical research, the article applies the concept of anchoring to theorise the flexibility of migrants’ adaptation and ‘settlement’. Simultaneity, multidimensionality and changeability of anchoring and the reverse processes of un-anchoring are examined here to bridge the divide between the ‘sedentarist’ and the mobility perspectives. The paper particularly focuses on anchors overlooked in the adaptation and integration literature, such as: performing gender; daily practices; spirituality; leisure activities; attachment to nature; material objects and technology; as well as constraining illnesses and addictions.  相似文献

This paper reports on the development and pilot evaluation of a Croatian school-based youth gambling prevention program “Who really wins?”. The program is aimed at minimizing risk and enhancing protective factors related to youth gambling. A short-term evaluation of the program was conducted with a sample of 190 first and second year high-school students (67.6% boys, aged 14–17 years; average age 15.61). An experimental design with two groups (Training vs. No Training) and two measurement sessions (pre-test and post-test sessions) was used to evaluate change in problem gambling awareness, cognitive distortions, knowledge of the nature of random events as well as in social skills. Results showed significant changes in the post-test sessions, which can be attributed to changes in the Training group. We observed a decrease in risk factors, namely better knowledge about gambling and less gambling related cognitive distortions. Immediate effects on protective factors such as problem solving skills, refusal skills, and general self-efficacy were not observed. Findings also show program effects to be the same for both boys and girls, students from different types of schools, for those with different learning aptitudes, as well as for those at different risk levels with regard to their gambling, which speaks in favour of the program’s universality. The program had no iatrogenic effects on behaviour change and shows promise as an effective tool for youth gambling prevention. Future research and a long-term evaluation are needed to determine whether the observed changes are also linked to behavioural change.  相似文献

This article attempts to provide a critical understanding of the dual signification of “precarity”. It explores what “precarity” as a concept may potentially offer to studies of the changing contemporary political economy of migration. It discusses shifting trends in global migration and point to tendencies for a possible convergence between “South” and “North”, “East” and “West”. Based on a review of current advances in research, it discusses, with reference to the classical work of Karl Polanyi, the potential for a contemporary “countermovement” which would challenge the precarity of migrants. Bringing forward the issue of the “space for civil society” the article addresses a still lingering democratic deficit in the global governance of migration.

Policy Implications

The article is relevant to policymakers, trade unions and civil society organizations. It contributes to the understanding of policy making processes in emerging multilevel global governance and focuses on issues of precarization, migration, and the implementation and accountability of human, migrant and labour rights.  相似文献

ABSTRACT

Following post-EU-accession migration, Poles currently form the largest group of foreign nationals in Norway and the second largest group of foreign born residents in the United Kingdom. Given the considerable volume of new arrivals, there is a growing literature on Polish migration to both countries; however, there is little comparative research on Polish migration across different European settings. By exploring how Polish migrants reflect on the possibilities of settlement or return, this paper comparatively examines the effects that permanent and ‘normalised’ mobility has on Polish migrants’ self-perception as citizens in four different cities. In addition to classic citizenship studies, which highlight the influence of a nation-state based institutionalised citizenship regime, we find that transnational exchanges, local provisions and inter-personal relationships shape Polish migrants’ practices of citizenship. The resulting understanding of integration is processual and sees integration as constituted by negotiated transnational balancing acts that respond to (and sometimes contradict) cultural, economic and political demands and commitments. The research is based on semi-structured interviews and focus groups with a total of 80 respondents, conducted in two British and two Norwegian cities that experienced significant Polish immigration, Oslo, Bergen, Bristol and Sheffield.  相似文献
