Humans can profoundly shape animal community dynamics, but such effects have rarely been evaluated for terrestrial carnivores. Humans affect carnivores in both spatial and temporal dimensions via the chance of human encounter and alteration of the landscape through urban development. We investigated three hypotheses regarding how humans mediate the sympatry of larger, dominant carnivores with their smaller, subordinate counterparts. We tested these hypotheses by examining the spatio-temporal dynamics of a dominant carnivore (coyote Canis latrans) and its subordinate competitor (red fox Vulpes vulpes) across an extensive urban park system. We found that dominant and subordinate carnivores exhibited strong and often opposing spatio-temporal responses to the probability of human encounter and urban development. Spatially, coyotes visited more highly developed sites less frequently while red foxes exhibited an opposing response. Temporally, both species avoided humans via nocturnal activity. Spatio-temporally, red foxes avoided coyotes at all sites and avoided humans at highly developed sites, whereas coyotes showed a positive association with humans at such sites. Our analysis indicates that areas with higher urban development might act as spatial refugia for some subordinate carnivores against interference from larger, dominant carnivores (a “human shield” effect). Our findings also reveal that broad-scale spatial avoidance is likely a crucial component of coexistence between larger, dominant carnivores and humans, whereas finer-scale spatio-temporal avoidance is likely a key feature of coexistence between humans and smaller, subordinate carnivores. Overall, our study underscores the complex and pervasive nature of human influence over the sympatry of competing carnivores inhabiting urban systems.  相似文献

The purpose of this literature review was to ascertain the concerns of White fathers raising their biological Black–White biracial sons, as well as the concerns of the sons themselves. Nine databases were selected for this review. The criteria for this review were (a) studies with a sample or subsample of White fathers, (b) studies with a subsample of Black–White biracial male participants (c) articles from scholarly peer reviewed journals, and (d) a date range between 2000 and 2016. A total of eight articles were found that matched the criteria. Of the eight studies, seven were qualitative with the number of participants ranging from 10 to 31, and the quantitative study had 317 participants. Three concerns were revealed for White fathers: dealing with racism, access to minority culture, and teachers’ expectations. Three challenges for the sons were self-identification, force-choice dilemma, and appearance. Implications and future research are discussed.  相似文献

Mindfulness is becoming more popular as emerging research demonstrates its benefits for self-care, by cultivating calmness and decreasing stress or anxiety. This pilot study aimed to measure the impact of a six-week Mindfulness course, modelled on the manualised treatment programme developed by Kabat-Zinn on the mental well-being, stress and resilience of undergraduate social work students in Northern Ireland. This was a mixed methods study involving two groups: (1) intervention group participants who attended a six-week Mindfulness course (April–May 2016) and (2) control group participants. Basic socio-demographic data were collected from all participants and all were invited to complete the Warwick-Edinburgh Mental Well-being Scale, the Perceived Stress Scale and the Resilience Scale during weeks 1 and 6. Statistical tests were used to compare mean scores from the scales, and qualitative data were manually analysed using thematic content analysis. Findings indicated significant changes in the scores for well-being, stress and resilience for the intervention group, but not for the control group. Mindfulness may not appeal to all students so it should not be a mandatory component of training, but may be offered as one of the wider approaches to self-care for undergraduate social work degree students.  相似文献

Overinclusive authorship practices such as honorary or guest authorship have been widely reported, and they appear to be exacerbated by the rise of large interdisciplinary collaborations that make authorship decisions particularly complex. Although many studies have reported on the frequency of honorary authorship and potential solutions to it, few have probed how the underlying dynamics of large interdisciplinary teams contribute to the problem. This article reports on a qualitative study of the authorship standards and practices of six National Science Foundation-funded interdisciplinary environmental science teams. Using interviews of the lead principal investigator and an early-career member on each team, our study explores the nature of honorary authorship practices as well as some of the motivating factors that may contribute to these practices. These factors include both structural elements (policies and procedures) and cultural elements (values and norms) that cross organizational boundaries. Therefore, we provide recommendations that address the intersection of these factors and that can be applied at multiple organizational levels.  相似文献

Advances in treatments have increased the longevity of people with HIV. The high prevalence of HIV among men who have sex with men (MSM) creates a greater risk for exposure that increases with age. Seroadaptation, which includes serosorting (sexual behavior and condom use based on knowing the serostatus of self and partners) and strategic sexual positioning (choosing receptive versus insertive anal sex), is sometimes used as an HIV risk-reduction strategy. This study examined seroadaptation, sexual communication, and HIV-risk behaviors in 420 sexually active HIV-negative MSM aged 40–81 years in South Florida via anonymous pen-and-paper questionnaire. Recreational drug use and serosorting (i.e., not using condoms if the partner said he was HIV-negative) were associated with higher risk for unprotected receptive anal intercourse. Younger age, greater number of partners, and serosorting were associated with higher risk for unprotected insertive anal intercourse. Understanding these behaviors in this group might help guide HIV-prevention efforts. Future research may examine the role of HIV-prevention medication (PrEP) in influencing sexual behavior in midlife and older MSM.  相似文献

Objective: To better understand why employment success is low, a case study was conducted to examine the influence of place on access to employment for persons with serious mental illness (SMI) residing in two northeastern Ontario communities (Rebeiro, in progress). Methods: Community-based participatory research methods were used to engage persons who experience SMI, decision-makers and providers in the research. Forty-six interviews were conducted, complemented by primary and secondary quantitative data sources.Results: While most consumers consider employment to be a key element of their recovery, employment rates for persons with SMI remain limited in northeastern Ontario, Canada. The findings of this case study reveal the importance of collaborative partnerships to fostering better employment outcomes in northeastern Ontario. Conclusion: The challenges of collaboration due to rural and northern tensions, as well as various jurisdictional and funding tensions existing at the level of community support the case for partnerships in the provision of employment services in northern and rural places.  相似文献

Understanding how children experience social work interventions is an important part of gauging whether what is provided is genuinely helpful. In this paper, we describe the findings from a research project using Q‐method, aimed at understanding what children involved with statutory services think about their social workers and how they experience the time they spend together. Using a pre‐existing practice framework, we explored skills including empathy, collaboration, and purposefulness from the point of view of children and young people. The participants in our study (n = 22) were insightful observers of social work practice, able to describe not only how they experienced time spent with their workers but also inferring differences in motivation and approach. In addition, workers who were described in similar terms by different young people were nevertheless experienced differently. This suggests not an archetypal “good social worker”—instead, there are skills that are good for specific children at specific times within the context of specific relationships.  相似文献

We encountered a problem in which a study's experimental design called for the use of paired data, but the pairing between subjects had been lost during the data collection procedure. Thus we were presented with a data set consisting of pre and post responses but with no way of determining the dependencies between our observed pre and post values. The aim of the study was to assess whether an intervention called Self-Revelatory Performance had an impact on participant's perceptions of Alzheimer's disease. The participant's responses were measured on an Affect grid before the intervention and on a separate grid after. To address the underlying question in light of the lost pairing we utilized a modified bootstrap approach to create a null hypothesized distribution for our test statistic, which was the distance between the two Affect Grids' Centers of Mass. Using this approach we were able to reject our null hypothesis and conclude that there was evidence the intervention influenced perceptions about the disease.  相似文献

From the time that development of a National Disability Insurance Scheme arrived on the agenda of the Australian Labor Government's 2008 Ideas Summit, the lives of disabled Australian citizens have been widely discussed, consulted on, planned for and acted on. This discourse analysis (Fairclough 2003; 2010) critiques the ways in which disabled lives have been framed in these high profile policy debates, with detailed focus on two key policy documents. The Shut Out Report: the Experiences of People with Disabilities in Australia (2009) (2009) and Disability Care and Support (Productivity Commission 2011) are both grounded in extensive national consultations and provide significant evidence about the ways that disabled Australians talk about the problems they face and the solutions they advocate. The paper employs the well‐known recognition‐redistribution debate of Nancy Fraser and Axel Honneth (2003) to interpret the findings that narratives of suffering, burden and marginalisation predominate in current policy conversations. This tends to push out discussions concerning the non‐redistributive aspects of disability reform, potentially contributing to non‐integrationist discourse entrenched over 150 years of policies of segregation. Minority voices advocating social integration are present but muted. At this stage, their influence is undetermined.  相似文献
