Silphids in urban forests: Diversity and function   总被引:2,自引:0,他引:2  
Wolf  Jordan M.  Gibbs  James P. 《Urban Ecosystems》2004,7(4):371-384
Many ecologists have examined the process of how urbanization reduces biological diversity but rarely have its ecological consequences been assessed. We studied forest-dwelling burying beetles (Coleoptera: Silphidae)—a guild of insects that requires carrion to complete their life cycles—along an urban-rural gradient of land use in Maryland. Our objective was to determine how forest fragmentation associated with urbanization affects (1) beetle community diversity and structure and (2) the ecological function provided by these insects, that is, decomposition of vertebrate carcasses. Forest fragmentation strongly reduced burying beetle diversity and abundance, and did so far more pervasively than urbanization of the surrounding landscape. The likelihood that beetles interred experimental baits was a direct, positive function of burying beetle diversity. We conclude that loss of burying beetle diversity resulting from forest fragmentation could have important ecological consequences in urban forests.  相似文献

We identify four common, but we argue fallacious, reasons social scientists object to theories that rely on environmental conditions to explain variation in the evolution of societies. First, some sociologists exclude environmental forces as beyond the domain of sociology. Second, environmental theories are often pejoratively labeled “determinist,” and rejected on those grounds. Third, environmental theories are regularly dismissed as being functionalist. Fourth, environmental theories are frequently charged with being Eurocentric and serving to justify colonialism and social inequalities. We argue that although there are examples of theories that fail in these regards, there is no inherent reason that environmental theories are more prone to these limitations and problems than are more sociologically “pure” theories. We argue that sociology should strive to be more transdisciplinary and can benefit from consideration of environmental conditions.  相似文献

Today, AIAN Elders are more actively engaged in their families and communities, encouraging the development of intergenerational programs, language and cultural revitalization, being stewards in research conducted in their communities, as well passing on their knowledge and experiences on how to live as healthy Native people. Elders have traditionally been quiet and observant of their environment, but the current and future cohorts of Elders are advocates, leaders, and culture bearers for their families and communities and they are now in positions of leadership. Western society acknowledges the value of traditional knowledge and AIAN Elders are viewed as exemplars of healthy aging and their lessons and experiences can be attributed to our own lives. This commentary highlights the paradigm shift in how society views older adults, specifically AIAN Elders and their role in health and wellbeing.  相似文献

Much of the literature on interpersonal trust is quantitative in nature, using scales developed primarily with White middle-class and upper-class adults. To understand how another racial group of a different socioeconomic background and age views interpersonal trust, we considered the experiences of 22 low-income Black adolescents. The adolescents participated in a relationship education program and were interviewed about their interpersonal trust experiences. Results of a qualitative data analysis revealed that most adolescents defined interpersonal trust based on honesty and fidelity, with a particular emphasis on monogamy in romantic relationships. Adolescents identified direct messages from family members and personal relationship experiences as sources of socialization for interpersonal trust. Although some adolescents reported that the relationship education program enhanced their understanding of and willingness to trust, others maintained that trust can only be learned through personal experiences. Though the adolescents generally trusted family members, they experienced challenges trusting friends and romantic partners. Despite this, adolescents considered interpersonal trust a vital and a necessary part of romantic relationships. We discuss implications of the findings for relationship stability and satisfaction.  相似文献

We sought to evaluate the efficacy of successive matching training for establishing generalized reflexive matching across 4 children with autism. In Experiment 1, differential reinforcement with delay fading was efficacious in establishing “yes” and “no” matching and nonmatching responses in 2 participants when 2 identical or nonidentical picture stimuli were presented. In addition, emergent visual–visual reflexive relational responses were observed using novel picture stimuli in a transfer test phase. In Experiment 2, differential reinforcement alone was efficacious in establishing matching and nonmatching responses in the other 2 participants when 2 identical or nonidentical objects were presented. Transfer to identical objects presented through touch (i.e., tactile discrimination) was additionally observed for both participants. Procedures in the study were adapted from the PEAK Relational Training System to aid in clinical replication, and the translational results have implications for language training with individuals with autism.  相似文献

Social work graduate programs have long grappled with ways to attract and retain students at the intersection of race and gender. The central structure of this analysis is a hermeneutic phenomenological qualitative study on the pursuit and persistence of African-American women in graduate Social Work programs at a Historically Black Institution (HBI). The data in this article were derived from the responses of 13 participants written in their own words. The themes that emerged around the pursuit of a social work degree were (a) service to Black communities, (b) resistance to misrecognition, and (c) a seat at the table. After sharing the salient characteristics of the findings, the article opens a discussion around the significance of HBIs in educating social workers to work in urban communities and the implications for policy and practice.  相似文献

Various approaches to personalisation are well-established in the UK social care sector and are now starting to ‘travel’ to other sectors. In this paper we report findings from an evaluation of a pilot to test elements of personalisation in the management of offenders in probation services within the English criminal justice system. Following a review of evidence from social care, three different approaches to personalised-practice were developed and tested on a small-scale in three separate sites. The evaluation finds that all three approaches were implemented reasonably successfully, but challenges were identified including that personalised approaches are more time-consuming, that staff need support to exercise professional discretion and that balancing greater choice with managing criminogenic risk requires new ways of conceptualising the relationship between case manager and service user. Overall, ‘deeper’ approaches to personalisation, such as co-production, will take time to emerge. This paper makes two important contributions to the debate on personalisation in public services. First, it addresses the question of how transferable the concept of personalisation is from the social care sector to other sectors in the UK, in this case the criminal justice system. Secondly, it outlines a methodology for developing and evaluating personalisation pilots, prior to a wider roll-out.  相似文献

Existing research demonstrates that parent and child gender may influence important aspects of family relationships; however, most research in this area has been conducted with non‐clinical samples. As clinicians, it is important to consider how gender impacts family relationships, particularly among vulnerable families. This study examined the intersections of gender role attitudes and parenting practices among 34 parents involved with the child welfare system and referred for clinical intervention. Using a mixed methods design, themes regarding gender role beliefs and parenting practices were found through qualitative interviews with parents. Findings suggested that fathers felt responsible for financially providing for their families and expressed challenges in communicating with mothers, and mothers described challenges they face because of a lack of father involvement. Parents also discussed a perceived need to monitor daughters closely while fostering the independence of their sons. Results of the qualitative analyses were supported by quantitative findings indicating significant differences in harsh and inconsistent discipline practices and clear expectations for girls compared to boys. The discussion addresses implications for clinicians, including how a feminist family therapy perspective may help promote client influence over traditional gender norms by questioning gender role attitudes and exploring alternate narratives that may impact family dynamics.  相似文献
