A desirable function for terrestrial urban ecosystems is the mitigation of nitrogen (N) pollution associated with cities and suburbs. To assist in maximizing this function, identifying locations of sources and sinks of N in the urban environment is crucial to inform management strategies. Lawns are an extensive land cover in urbanized landscapes, and in general, they have demonstrated the capacity to function as a sink for N inputs. How N is cycled by lawns, however, is likely not uniform across the physical heterogeneity or management activities that exist in lawns. We investigated the influence of heterogeneity in light availability on N cycling in lawns that were irrigated but not fertilized. Light availability is affected by tree canopy and built structures and is, therefore, heterogeneous both within individual lawns and among lawns. Light is expected to control N retention and loss through effects on primary productivity. We experimentally examined N regulation over one calendar year by measuring net primary production (NPP), N retention using an isotopic tracer, and N leaching in existing unfertilized lawns under heterogeneous light conditions. We used a budgetary approach to estimate gaseous N loss which we assume is primarily via denitrification. Light functioned as a limiting resource for primary productivity. From low to high light conditions, annual NPP increased 177 to 430 g C?m?2?y?1 and retention of N isotope tracer increased from 50 to 65% as a result of increased retention in plants. Nitrate leaching losses were low overall and were not affected by light levels. Light availability regulated the fate of N inputs and unfertilized lawns may function as substantial sinks for reactive N through storage in the terrestrial system and N loss by denitrification. However, whether or not denitrification is generally an N sink will depend on the ratio of non-reactive (i.e., N2) to reactive (i.e., N2O, NO) denitrification products. Overall, we find that effective strategies for managing N sources and sinks in cities will likely need to consider light availability, particularly in systems receiving water subsidies via irrigation.  相似文献

Food insecurity is a common social issue and households look to assistance from food pantries, which often have difficulty supplying fresh or nutritious food. A substantial amount of produce is left in the fields, which can be collected through gleaning. In a focus group with volunteer gleaners at a faith-based nonprofit organization that attempts to fill the gaps of food insecurity, the motivations, challenges, and benefits of volunteering were examined. Volunteering in gleaning generated a sense of collective purpose and community; it addressed deeply held religious and spiritual impulses; and it puts volunteers directly in contact with nature.  相似文献

The question of how the individual and group relate is one that has long interested social theorists. Changes in family form and structure in the contemporary West resituate this question in a contentious public debate regarding how the prevalence of new family forms may contribute or be deleterious to the well-being of individuals and families. Sociological discourse on marriage and the family generally tends to mirror this debate by dichotomizing individualism and commitment and self and marriage, resulting in an obfuscation of our understanding of the forms and styles in marriage. In order to clarify and advance this discussion, we show how individualism and commitment are mutually required in a modern world. We follow this by outlining a logically-derived typology that, along with a committed individualist and a group conformer, includes two intermediate types: a self-regulator and a relationship negotiator. We empirically demonstrate the utility of these types by showing how they correspond with the ways that interviewees talk about marriage in six local congregations, and we suggest various social factors that may particularly impact the development of local marriage cultures. These types provide a theoretical frame for understanding how individualism and commitment are intertwined and require each other.  相似文献

Motivational interviewing (MI), an evidence-based approach with empathy as a key principle, effectively addresses client concerns found in the child welfare population. Training social workers in MI, and to be empathic, would increase the likelihood of better service delivery. Live supervision (LS) is a form of training that provides real-time feedback by clinical supervisors. This randomized comparison trial compared the effectiveness of LS or Teaching as Usual (TAU) on empathy in 54 MSW and BSW social work students. TAU involved students receiving online modules and assigned readings. Data were collected at baseline, after the interventions, and at five months follow-up. Differences in perceived empathy and empathic behaviors were measured by the Motivational Interviewing Treatment Integrity (MITI) and Toronto Empathy Questionnaire (TEQ). The study also assessed whether demographic variables or perceived empathy (TEQ) predicted empathic behaviors (MITI). Results indicate that, while both groups improved on empathy as measured by the MITI and TEQ, the LS group demonstrated more improvement. Demographic variables had no impact on empathy. The TEQ and MITI also did not demonstrate predictability suggesting the complexity of measuring empathy. The implications for social work education and future training are discussed.  相似文献

Objective: The purpose of this pilot study was to evaluate the Resilience and Coping Intervention (RCI) with college students. Participants: College students (aged 18–23) from a large Midwest US university who volunteered for a randomized controlled trial during the 2015 spring semester. Methods: College students were randomly assigned to an intervention (n = 64) or a control (n = 65) group. Intervention participants received three 45-minute RCI sessions over subsequent weeks. All participants completed pre- and post-intervention assessments at the beginning of Week 1 and end of Week 3. Student resilience, coping, hope, stress, depression, and anxiety were assessed. Results. RCI participants reported significantly more hope and less stress and depression from Week 1 to Week 3 compared with control participants. Results for resilience also approached statistical significance. Effect sizes were small to moderate. Conclusions: This study found preliminary evidence that RCI is an effective resilience intervention for use with college students.  相似文献

Objective: The ways that college students cope with stress, particularly interpersonal stress, may be a critical factor in determining which students are at risk for impairing mental health disorders. Using a control-based model of coping, the present study examined associations between interpersonal stress, coping strategies, and symptoms. Participants: A total of 135 undergraduate students from 2 universities. Methods: Interpersonal stress, coping strategies, depression, anxiety, and somatization were assessed via self-report. Results: Students reporting more interpersonal stress reported more depression, anxiety, and somatization, and they reported less use of engagement coping strategies and greater use of disengagement coping strategies. Engagement coping strategies accounted for a significant portion of the association between interpersonal stress and mental health symptoms. Unexpectedly, coping strategies did not moderate the association between stress and mental health symptoms. Conclusion: Interventions designed to improve students' coping strategies may be an effective way to reduce mental health problems on college campuses.  相似文献

How do cultural meanings influence how people experience work‐life demands? Much research, especially quantitative research, on the effects of structural work and family conditions does not account for employees’ cultural beliefs about the meaning of work in their lives. This article uses unique survey data to investigate the effects of employee embrace of elements of the “work devotion schema”—a cultural model that valorizes intense career commitment and organizational dedication—on their sense of “overload,” an experience that includes feeling exhausted and overloaded by all one's roles, net of actual hours on the paid job and family responsibilities. We argue that by cognitively, morally, and emotionally framing work as a valued end, the work devotion schema reduces feelings of overload. Using a case of senior women researchers and professional service providers in science and technology industries, we find that those who embrace work devotion feel less overloaded than those who reject it, net of work and family conditions. However, this effect is curtailed for mothers of young and school‐aged children. We end by discussing implications for flexibility stigma and gender inequality.  相似文献

The study purpose was to develop and pilot an undue influence screening tool for California’s Adult Protective Services (APS) personnel based on the definition of undue influence enacted into California law January 1, 2014. Methods included four focus groups with APS providers (n = 33), piloting the preliminary tool by APS personnel (n = 15), and interviews with four elder abuse experts and two APS administrators. Social service literature—including existing undue influence models—was reviewed, as were existing screening and assessment tools. Using the information from these various sources, the California Undue Influence Screening Tool (CUIST) was developed. It can be applied to APS cases and potentially adapted for use by other professionals and for use in other states. Implementation of the tool into APS practice, policy, procedures, and training of personnel will depend on the initiative of APS management. Future work will need to address the reliability and validity of CUIST.  相似文献

Understanding how survivors of complex trauma navigate towards resources can inform the design of interventions and health promotion strategies. However, there are little data on the resilience and help‐seeking experiences of this group or others who have experienced institutional abuse in childhood. This empirical study sets out to illustrate the help‐seeking experiences of Irish emigrant survivors of institutional childhood abuse (ICA). Twenty‐two survivors of ICA were purposefully recruited from community organisations in the UK and data were collected via semi‐structured interviews. As a result of negative initial help‐seeking experiences in Ireland, most participants engaged in long periods of self‐management and disclosed information about their childhood as part of a redress scheme in later life. Outside of this scheme, turning points, such as illness or family problems, and the needs of children were influential in seeking help. Peer support networks played an important role as a trusted signposting pathway towards formal interventions. Participants identified interpersonal barriers to formal help‐seeking as helping professionals' failure to share control, insensitivity to identity loss and literacy issues, and the lack of explicit boundaries. The paper concludes with a discussion about the implications for research and future practice.
‘This empirical study sets out to illustrate the help‐seeking experiences of Irish emigrant survivors of institutional childhood abuse’
Key Practitioner Messages:
  • Turning points, such as illness and bereavement, and the desire to provide for children, influence the help‐seeking of survivors of ICA.
  • Irish emigrant survivors of ICA cite failure to share control, insensitivity to identity loss, literacy issues and the lack of explicit boundaries as barriers to help‐seeking.
  • General awareness of ICA can help practitioners in low‐threshold services prevent against culturally insensitive practice.
  • Peer support networks can provide uniquely trusted signposting towards formal interventions.
