American ecologists recently began to address the ecology of cities. Concurrently, higher education institutions have developed sustainability education programs and instituted sustainability policies and projects. This paper draws together these two disparate areas by examining the nitrogen (N) budget of the Twin Cities campus of the University of Minnesota. We addressed the question: what were the annual inputs, outputs and internal cycles of N on the University of Minnesota Twin Cities campus? We found that 508 Mg N yr-1 were brought into the campus and 494 Mg N yr-1 were emitted from the University of Minnesota campus. The largest N inputs were abiotic fixation (conversion of N2 to NOx by combustion) and food for humans and animals. The largest N output was NOx, followed by wastewater. Our results expand the understanding of the ecology of institutions within an urban area and provide an opportunity for improving urban ecology education and environmental policy at educational institutions.  相似文献

Work with couples is one of the more widely practised forms of counselling or psychotherapy, yet seems to have found it difficult to establish its own identity and theoretical base. A theoretical tradition specific to work with the couple relationship has, however, developed over the past 40 years. Recently, this tradition has become more clearly demarcated and has begun to show signs of vigorous growth. It is important for therapists whose primary identification is with individual or family therapy, but who work with couples, to be familiar with this theoretical tradition, and with its practice implications. This paper selects six aspects of theory relating to couples therapy that the author has found useful in practice, and seeks to show how, separately and together, they can illuminate the nature and dynamics of the couple relationship.  相似文献

We present an analysis and discussion of the tanda, a multiperson pooled credit and savings scheme (a rotating credit association or RCA), as described by two informants from Mexican immigrant communities in California. In the tanda, participants contribute regularly to a common fund which is distributed to participants on a rotating basis. We analyze the tanda at multiple levels (as a mathematical, cultural, and distributed practice) and identify points of intersection and conflict. Contrary to many formal or school-based conceptions of mathematics, mathematical work in the context of the tanda is in service of, and intimately tied up with, cultural goals and values. Likewise, cultural means and mathematics are employed to personal ends. We argue that the tanda should be of enduring interest, particularly among educators interested in bringing more authentic, culturally-relevant mathematics into classroom settings, because it so clearly illustrates how mathematical and cultural processes can interact in the context of personal goals, and provides a potentially valuable template for engaging, consequential, and successful mathematics.  相似文献

This paper investigates the extent to which the outcomes of the 2008 Research Assessment Exercise in the UK, determined by peer review, can be explained by a set of quantitative indicators. Three cognate units of assessment are examined in detail: business and management, economics and econometrics, and accounting and finance. The main finding is that each of the three components of research activity (namely, research output, esteem and research environment) is highly correlated with various quantitative indicators. A further finding is that the judgement of the Research Assessment Exercise panels was biased in favour of Russell Group universities. There is also evidence of bias by the economics and econometrics panel. The results support the use of quantitative indicators in the research assessment process, particularly a journal quality index. Requiring the panels to take bibliometric indicators into account should help not only to reduce the workload of panels but also to mitigate the problem of implicit bias.  相似文献

This article gives an overview of the problem of street children in Greece, within the context of global research on street children. The article draws on preliminary findings from recent research on street children in the urban centre of Athens. This is an under‐researched area, with weak policy responses to a problem associated with recent patterns of European migration (in the Greek case, chiefly from Albania). Methods used include observational research and in‐depth interviews with street children, policy actors and professionals.  相似文献

The 2nd Australian and New Zealand Family Therapy Conference, held in Melbourne in July 1992, invited those making presentations to address the Conference theme Family Therapy … what's in a name? In a closing address to a plenary session of the Conference, I used the metaphor of first names (family) and surnames (therapy) to suggest that names are central to issues of identity. Our first name of “family” differentiates us within the larger group who share the surname “therapy”; but what does it mean to belong to the larger group sharing the name “therapy”? Historically, much of family therapy's energy has gone into issues concerned with establishing difference — difference within family therapy in terms of models and approaches, and difference from other approaches to therapy. Yet now perhaps family therapy would benefit from exploring what it shares in common with others who hold the same surname of “therapy”, with the possibility such dialogue could lead to mutual enrichment.  相似文献

Ocean cruising: a sailing subculture   总被引:1,自引:0,他引:1  
Just after dawn, an English couple in their 30's haul up their anchor and motor across the stillness of Suva harbour. The hurricane season is approaching and they are embarking on the 2–3 week trip to Bay of Islands New Zealand for the southern summer. Three months earlier, as their yacht lay aground on the fringing reef of uninhabited Suvarov atoll, they wondered if they'd ever reach New Zealand. But, with the help of other cruisers and lucky tides their steel 36 footer was clear and safe in under 24 hours. What was to be a one year trip around the north Atlantic was now happily way off course in the South Pacific and likely to remain so for some time. That is just a glimpse of one small aspect of ocean cruising, the subculture of interest here. However, throughout the paper the ethnography of cruising is developed further. A model is proposed to show how individuals come to share the subculture ideology and then to participate in the lifestyle. Subsequently, I will place ocean cruising in the context of subculture theory by expanding the ethnography and relating cruising to other subcultures.  相似文献
