Urban forests provide valuable ecosystem services, but their long-term viability is often threatened by low tree recruitment due to seed and/or microsite limitation. Distinguishing between these two causes of low recruitment has important management implications, but has been little studied in urban environments. We tested for seed and microsite limitation in an urban forested park in Seattle, Washington, USA by adding conifer tree seeds and seedlings to experimental plots in which we manipulated microsite conditions by removing invasive ivy (Hedera spp.) and adding deadwood. We found that natural seed production was low, and adding seeds increased the number of observed seedlings. Furthermore, adding deadwood increased seedling survival, whereas removing Hedera did not have strong effects. Seed limitation is frequently addressed through management actions such as sowing seeds and transplanting seedlings, and our results suggest that such actions address a critical barrier to tree recruitment in urban forests. However, we also observed strong microsite limitation. At our study site, microsite limitation can be addressed primarily by adding deadwood and retaining coarse woody debris on site. Addressing microsite limitation may be a critical component of successful management efforts to improve tree recruitment in urban forests, and should not be overlooked. Furthermore, our study highlights the need for active monitoring and data analysis alongside management, since the most apparent threat (widespread cover of an invasive plant in this case) may not be the primary limit on suitable microsite conditions. 相似文献

The networked age promises global digital cultures with flattened power relations, given the affordances of information and communication technologies to collapse distance, enable easier cross-country collaborations and create new opportunities for knowledge production and sharing. In the academic domains, indications are that knowledge patterns continue to reflect physically based geopolitical realities – where knowledge from the South is still peripheral while knowledge from the North still dominates in terms of all the conventional metrics. This study explores the potential role of digital affordances to challenge structural Northern bias and generates questions about knowledge production and dissemination in the climate change knowledge domain. It is framed by the field of scholarly communication within an African setting and by the emergent field of climate change which is fraught with debates and contestations, particularly regarding mitigation and adaptation. It draws on Southern theory which interrogates the global dynamics of knowledge production and dissemination. It explores the intersection of the discoverability and visibility of local climate change research methodologically from the outside in, through an experiment of searches for ‘climate change/South Africa’ and from the inside out by reviewing the online presence of one climate change group in a top-ranked African university. 相似文献

ABSTRACTThis article posits that an integrative research partnership model can assist school counselors in addressing the marginalization of transgender students in schools through staff development. A methodological integration of action research and program evaluation through quantitative and qualitative data collection is explained, and a collaborative process is highlighted. A case example is provided to demonstrate the use of the design. 相似文献

‘Let's Talk About Children’: Investigating the Use of a Family‐focused Intervention in the Gambling Support Services Sector 下载免费PDF全文

The family‐focused mental health intervention, ‘Let's Talk About Children,’ has positively influenced the lives of families affected by parental mental illness. This paper outlines the use of this brief, strengths‐based intervention for parents with gambling and other co‐occurring issues from the gamblers’ support services sector. Over a six‐month period, a training manual and accompanying resources were adapted for the gamblers’ support services sector and a targeted training session developed. Nine problem gambling counsellors from three Victorian gambling support services trialled the Let's Talk About Children intervention over a four‐month period. Qualitative data were gathered through focus groups, interviews, and practice enquiry groups to determine the impact of the Let's Talk About Children model for gambling support services. The results are presented as ‘practice wisdoms and recommendations’ reporting on the impact of the trial and to provide some guidance to support others in the implementation of a specific family‐focused intervention. This paper reports on the first exploratory trial of Let's Talk About Children for the gambler's support services sector in Australia. 相似文献

This study extends Flores et al.'s ( 2006 ) 36‐year analysis of racial/ethnic minority (REM) career research to identify recent trends in choice of topics and leading individual and institutional contributors. The authors identified 166 articles on REM career research published from 2005 to 2015 in the Journal of Vocational Behavior, The Career Development Quarterly, the Journal of Career Assessment, and the Journal of Career Development. Of these studies, 92% were empirical, with more than three quarters of these using quantitative rather than qualitative methodology. Most frequently, the empirical studies (n = 153) were based on samples of high school (30.7%) or undergraduate (34.6%) students. The authors discuss the implications of their findings and suggest ways to expand REM career research in the future. 相似文献

This article considers the extent and nature of social work and social care practitioners' experience of working with service users whose lives are affected by the problematic use of alcohol or other drugs (AOD). It draws on the findings of a national study of ‘working with alcohol and drug use’ which was conducted in England in 2010–2011. The study reported here comprised an online survey of front-line practitioners (n = 597), complemented by 12 practitioner focus groups and interviews with 21 key informants from participating local authorities and substance use treatment services. This paper focuses primarily on data from one element of the survey. Findings indicate that the great majority of staff encountered service users who are affected by AOD problems at some level, although there were differences between groups of practitioners in the extent and nature of AOD problems for different groups of service users. The differential experiences of staff according to their client groups underlines the need for education and professional development not only to provide training on working with AOD but to ensure that training is contextualised and relevant to practitioners across the range of social work and social care services. 相似文献

Researchers, health and social care workers often seek to understand the perspectives of children; but gathering views directly from children can present difficulties. Parents are often asked to provide accounts of children's feelings or opinions on the assumption that their proxy reports are accurate and unproblematic. This qualitative thematic analysis of open‐question responses from 352 parents and 73 disabled children examines their accounts of the impact of short break services on disabled children. Participants' perspectives differed; children tended to describe immediate outcomes such as enjoying activities and participation; parents acknowledged these, but focused on longer term developmental outcomes for children. 相似文献

An exploratory teaching approach was inspired by the communicative experiences of d/Deaf students in tertiary education. ‘Theory of Mind’ has been used by some to describe the capacity to appreciate that views of others may be different from our own, a concept that could provide a different way for students and educators to understand the barriers identified. An adapted assessment highlighted challenges faced and a communication group provided opportunities for extending personal understandings of social settings. Emerging ideas to inform practice and potential implications for inclusion have relevance for other contexts. 相似文献

Beginning in 2000, in economically advanced countries, a remarkable bifurcation in fertility levels has emerged, with one group in the moderate range of period total fertility rates, about 1.9, and the other at 1.3. The upper branch consists of countries in Northern and Western Europe, Oceania and the United States; the lower branch includes Central, Southern, and Eastern Europe, and East and Southeast Asia. A review of the major theories for low-fertility countries reveals that none of them would have predicted this specific bifurcation. We argue that those countries with fertility levels close to replacement level have institutional arrangements, and related policies, that make it easier, not easy, for women to combine the worker and mother roles. The institutional details are quite different across countries, suggesting that multiple combinations of institutional arrangements and policies can lead to the same country-level fertility outcome. Canada, the only exception to this bifurcation, illustrates the importance of the different institutional structures in Québec compared to the rest of Canada. 相似文献
