Northeastern Illinois is under heavy urban sprawl pressure leading to changes in land-use and negative impacts on existing wetlands directly adjacent to these new developments. Determining the impact of land-use changes on wetlands is important as it can have management and preservation implications within this region. One tool to evaluate these changes is the Floristic Quality Assessment (FQA), a method based on plant species composition at a site and the individual species habitat affinity and disturbance tolerance. The objectives of this study were to: 1) determine how wetland size, impervious surface, and distance from development influence FQA indicators and 2) determine if period (before/after development) and buffer size affect FQA indicators. Fourteen wetlands located in Northeastern Illinois were surveyed during 2004 through 2006 (prior development) and revisited in 2008 (post development). Positive correlations between wetland size and FQA indicators and between impervious surface and percent native species were found. In addition, species richness increased after development occurred and wetlands with larger buffers had higher percentages of native species. This study has demonstrated that larger wetlands are more diverse and land-use changes may not decrease wetland plant diversity in the short term in an urban setting.  相似文献

Globalization and increased mobilities have multiplied cross-border transactions not only in the economic sphere but have also a major impact on human relationships of intimacy. This can be seen in the increased volume of differently mediated forms of international marriage, not just straddling ‘east’ and ‘west’, but within Asia and across different ethnicities and nationalities. International marriage raises a host of social issues for countries of origin and destination, including challenges relating to the citizenship status and rights of the marriage migrant. This paper examines the negotiation of citizenship rights in the case of commercially matched marriage migrants – namely Vietnamese women who marry Singaporean men and migrate to Singapore as ‘foreign brides’. While they are folded into the ‘family’ – what is often thought of as the basic building block of the nation in Asian societies – they are not necessarily accorded full incorporation into the ‘nation’ despite Singapore's claims to multiculturalism. This is particularly salient at a point when cross-nationality, cross-ethnicity marriages between Singapore citizens and non-citizens are on the increase, accounting for over a third of marriages registered in Singapore in recent years. Vietnamese women who marry Singaporeans are positioned within the nation-state's citizenship regime as dependents of Singaporean men, having to rely on the legitimacy of the marriage relationship as well as the whims of their husbands in negotiating their rights vis-à-vis the Singapore state. Drawing on interviews and ethnographic work with 20 Vietnamese women who are commercially matched marriage migrants, the paper first focuses on the vulnerable positions these women find themselves, particularly given difficulties in forging their own support networks as well as weaknesses of the civil society sector in what has been called an ‘illiberal democracy’ characterized by a political culture of ‘non-resistance’. The paper then goes on to examine the way they negotiate rights to residency/citizenship, work and children within webs of asymmetrical power relations within the family and the nation-state. We draw on our findings to show that citizenship is ‘a terrain of struggle’ within a multicultural nation-state shaped by social ideologies of gender, race and class and negotiated on an everyday basis within spheres of family intimacy.  相似文献

Burgeoning technology provides instant access to information and communication. Responsible adults are concerned about the material accessed by adolescent technology users. From an ecological system's lens, using a mixed-methods design, the current study identified adolescent and parent perceptions of parental mediation of adolescent interactive technology use (i.e., cell phones, Internet). Eighty adolescents (16–18 years of age) and their parents (n = 113) participated in the study that identified generational differences in perceptions of parental mediation, techniques for mediating interactive technology (i.e., monitoring data and usage, active mediation, rules, restriction), and adolescent perceptions of the process of parental mediation. We used the results to propose principles for parental mediation of adolescent interactive technology use and provide directions for future research.  相似文献

This article reports some findings from an ESRC‐funded research project which has been examining the development of criticality in undergraduate students, taking social work and modern languages as contrasting disciplines. This twin‐track study aims to develop the conceptualisation of ‘criticality’ in the context of empirical research. This article examines the development of criticality in final year social work students, where the practice learning experience is predominant. The analysis is framed by the project's developing theoretical conceptualisation of criticality.  相似文献

The need for social workers to develop expertise in critical reflection is now a dominant theme in the literature. How this expertise is achieved, however, remains under‐explored in an environment increasingly focused on outcomes, evidence of performance and teachers' preoccupations with curriculum content and assessment. Students' understanding of critical reflection and how, if at all, their social work education assists in developing this capacity, continue to be under‐represented.

Applying a ‘deep‐learning’ framework, this article outlines an attempt to engage final year social work students in a teaching, learning and assessment exchange that promotes critical reflexivity. It presents the thinking behind the evolution of a unit focused on social work in public welfare and health settings. Using their final assessment exercise in which they are asked to review their learning, it then offers students' responses to that unit. In particular, the paper highlights the personalised practice visions offered by students as they seek to locate themselves, personally and professionally, before making the identity‐challenging transition from student to qualified practitioner.  相似文献

The life course perspective emphasizes that past economic experiences and stage in the life course influence a family's ability to cope with negative life events such as poor health. However, traditional analytic approaches are not well-suited to examine how the impact of negative life events differs based on a family's past economic experiences, nor do they typically account for the potentially spurious association between negative life events and family economic well-being. We use finite mixture modeling to examine how changes in parental health affect children's exposure to poverty. We find that for some children the association between family head's health and children's exposure to poverty is spurious, while for other children family head's poor health is associated with increased risk of economic deprivation. The extent to which a family head's poor health alters children's economic well-being depends on a child's family's underlying economic trajectory and past history of exposure to disadvantage.  相似文献

Associations between interparental conflict and infant reactions were examined. Infants' history of exposure to interparental conflict and infant reactive temperament were examined as moderators. A community sample of 74 infants, aged 6–14 months, participated with their parents. Behavioral observations were made of parents' marital conflict and their infants' reactions. Parents reported on their emotional states during conflict, infants' history of exposure to interparental conflict, and infant temperament. Multilevel modeling indicated that infants showed differential responses to marital conflict; destructive and depressive conflict were associated with increased infant discussion attending and negative reactions, whereas constructive conflict was associated with decreased discussion attending and negative reactions. Infants' history of exposure to marital conflict and infant reactive temperament emerged as moderators.  相似文献

Due to concerns over Thai adolescent risky behaviors, effective prevention strategies are needed. Determining the role neighborhood context plays in program engagement and outcomes may inform these strategies. This study includes 170 mother-adolescent pairs (M = 13.44, SD = .52) in Bangkok, Thailand in a prevention program for adolescent substance use and sexual risk. Neighborhoods were related to engagement, which was critical to outcomes. Neighborhood disorganization was related to confidence in program effects and program completion. Completion was related to increased ATOD communication. Neighborhood cohesion was related to less program enjoyment, while neighborhood social control was related to more enjoyment. Enjoyment was related to increased ATOD communication and formation and monitoring of alcohol rules. Prevention strategies should focus on neighborhood contexts and enhancing engagement.  相似文献
