Cannabis is the most widely used illicit drug worldwide, and the most commonly used illicit drug in Canada, among postsecondary student populations. This cross‐sectional study qualitatively assessed 112 high‐frequency, cannabis‐using university students in Canada: It examined their subjective expectations regarding what they anticipated their cannabis use would look like in the short‐ and mid‐term future and explored factors they saw potentially contributing to changes in their prospective drug use. Results indicated that participants believe that decisions about future cannabis use will be influenced by several contextual factors, including education and employment responsibilities, intimate relationships, and peer associations. These findings help illuminate the natural evolution of cannabis use and can guide the development of interventions for high‐frequency cannabis users in the future.  相似文献

The literature has often suggested that network leadership is different from leadership in hierarchical/single-agency structures. While this difference has been assumed, relatively little research has been conducted to determine whether such a distinction between network and hierarchical leadership actually exists. This study addresses this gap in the literature using data from 417 public sector leaders. We compared the leadership behaviors exhibited by a leader in their government agency with the behaviors exhibited by that same individual while leading his or her network. The leadership behaviors were classified into one of three categories common in the leadership literature. The results indicate that while the frequency of organization-oriented behaviors vary widely between the agency and network contexts, leaders in their networks focus more on people-oriented behaviors and less on task-oriented behaviors when compared to leading their agency.  相似文献

One hundred forty-six abdominally obese adults age 60-80 yr were studied to investigate the interaction between cardiorespiratory fitness (CRF) and obesity on functional limitation. Obesity was determined by fat mass (FM), CRF was determined by a maximal treadmill test, and functional limitation was based on 4 different tasks that are predictive of subsequent disability. Both FM (r = -.34, p ≤ .01) and CRF (r = .54, p ≤ .01) were independently associated with functional limitation in bivariate analysis.After further control for sex, age, and the interaction term (CRF × FM), FM was no longer independently associated with functional limitation (p = .10). Analyses were also based on sex-specific tertiles of FM and CRF. The referent group demonstrated significantly lower functional limitation than the low-CRF/low-FM and the low-CRF/high-FM groups (both p ≤ .05). These results highlight the value of recommending exercise for abdominally obese adults.  相似文献

This article will outline the response of housing management to the implementation of community care policy in the North East. It will locate housing's role within the broader development of community care policy, and briefly review the reasons for housing's relatively late arrival as a key partner, alongside social services and health, in the planning and delivery of services. Using information gathered from interviews with housing professionals, part-time housing students, voluntary organizations, and workers within health and social services, it outlines and evaluates five main factors which appear to be affecting the successful integration of housing management into the process of planning and delivering community care services in the North East.  相似文献

Sociological debates on youth engagement with electoral politics play out against a backdrop of supposed ‘decline’ in civic participation (e.g. Putnam 2000 , Norris, 2011 ), in turn contextualized by theories of individualization in ‘late’ or ‘reflexive’ modernity (Beck, Giddens). However, the enfranchisement of 16 and 17 year olds in the 2014 Scottish Independence Referendum catalysed remarkably high levels of voter turnout among this youngest group, and was accompanied by apparently ongoing political engagement. We explored this engagement among a strategic sample of young ‘Yes’ voters, in the immediate aftermath of this exceptional political event. Analysis of qualitative interview data generated an unanticipated finding; that interviewees narrated their political engagement biographically, articulated their referendum participation reflexively, and located their new political ideas, allegiances and actions in the context of their own transitions to ‘independent’ adulthood. This inspired us to rethink young people's political engagement in relation to youth transitions. Doing so enables a synthesis of divergent strands in the sociology of youth, and offers new insights into the combinations of ‘personal’ agentic and ‘political’ structural factors involved in young people's politicization.  相似文献

Due to extensive areas of impermeable surfaces, combined sewer overflow (CSO) is currently a major problem in urban areas across the United States. In CSO systems, sewage can travel through underground pipes to be decontaminated in treatment facilities, or it can combine with stormwater after a precipitation event and discharge into local waterways. Many cities are implementing green infrastructure installations, which use vegetation and bioactive soil microbial communities to enhance soil water-holding capacity, thereby minimizing CSO events. Understanding the factors that structure soil microbial communities in green infrastructure will facilitate more effective management of these engineered ecosystems; however, few studies to date have evaluated ecological patterns and processes of microbes in the urban environment. Nitrogen loading is known to be a major factor structuring fungi and bacteria in non-urban soils, and since cities also contain large populations of canines, N-rich urine deposition is a potential factor that could be important for structuring soil microbes in ground-level green infrastructure installations. Our study investigated the effects of canine urine on the urban soil microbial communities in a greenhouse experiment by treating Liriope muscari, a common plant found in New York City green infrastructure, with different concentrations of canine urine for 4 weeks in an experimental setting. We found that urine application significantly decreased total soil microbial biomass and microbial richness, and increased water runoff volume. These findings indicate that canine urine may have negative consequences for soil water-holding capacity and nutrient cycling in urban green infrastructure installations by directly decreasing the abundance and richness of soil microbial communities.

Undergraduate social work programs are well-positioned to recruit students to gerontology, but little is known about how well curricular activities help foster students' commitment to the field. This study considers whether a small group of undergraduate students' interactions with older adults positively impacts students' plans to work with older adults; perceptions of skills; and feelings of comfort and competency in working with older adults. Experiences from this study suggest that experiential learning can positively impact students' perceptions of work with older adults, but may not be enough to draw students to the field. Implications for undergraduate education are discussed.  相似文献

In 2005 225,000 people marched through Edinburgh enjoining the G8 to ‘Make Poverty History’. The coalition's own assessment of their campaign highlighted the importance of media by focusing on the extent of media coverage. Media outlets, however, have their own agendas. Detailed analysis of newspaper coverage preceding the G8 Summit suggests a disjuncture between campaign objectives and media frames. This paper explores how far newspaper accounts of G8-related protests were ‘framed’ in terms of social movement aims, and how far in terms of anticipated violence. Our findings lead us to caution against an uncritical equation of ‘coverage’ and ‘success’, offering a more nuanced account of the interplay between social movements and media.  相似文献
