Early cities depended on local, solar-based energy resources for their metabolism. Over time, cities have become increasingly dependent on fossil fuels, both directly and indirectly, as they facilitate exploitation of solar resources from much farther away. Alternatives to fossil fuels, typically generated locally, often provide lower surplus energy to society. As cities consider the transition back to solar-based energy resources, it becomes necessary to understand the capability of the solar-based economy to provide e.g. energy (including food) from nearby lands. To do so, we compared the energy metabolism (respiration) of a typical rust-belt city, Syracuse, NY, with the net primary production in the surrounding county (production) over its development (1840–2005). We calculated the ratio of respiration to production (R:P) and examined how this ratio changed during the periods of industrialization, shifts in major fuel types, and deindustrialization. We found that from 1840 to 1950 respiration became increasingly centralized in the urban core; since then it has become more diffused. Urban respiration exceeded production in the county by 9:1 in 1930, and it remains just under 2:1 today. Respiration reached an absolute (67 PJ) and a per capita (339 GJ) maximum in 1970, then fell by 40 % and 20 % respectively, due to deindustrialization and population losses. Conversely, production increased 480 % from its lows in 1930 because of reforestation and improved agricultural yields. What this means is that to achieve a higher P:R ratio requires either increased production of food and fuels in areas surrounding the city, or decreased per capita energy consumption.  相似文献

This article advances the psychology of working theory by developing a parallel change‐based paradigm to guide interventions at the level of individuals (i.e., the psychology of working counseling) and systems (i.e., the psychology of working systemic intervention). The change paradigm presented in this article includes (a) a needs assessment encompassing survival, social connection/contribution, and self‐determination and (b) input on the mobilization of agentic action that includes critical reflection and action, proactive engagement, social support, and community engagement. The needs assessment and agentic action aspects of this approach can be used to foster change in individual counseling, advocacy, and systemic intervention. Case examples reflecting a systemic intervention and an individual counseling vignette are presented along with implications for research, such as explorations of the impact of these change models on client outcomes and systemic change efforts.  相似文献

Young adults from divorced families experience clear emotional distress despite most not meeting diagnostic criteria for emotional disorders. Laumann-Billings and Emery (2000) developed the Painful Feelings About Divorce (PFAD) scale to assess the emotional distress emerging adults feel regarding childhood parental divorce. The study sample is undergraduates predominately between the ages of 18 and 22. This study adds to the literature by (a) further demonstrating the PFAD scale reliability and validity, (b) including participants with both divorced and separated but never married parents, and (c) assessing generalizability of the PFAD with a more diverse socioeconomic sample.  相似文献

Instrumental support can foster or ameliorate parent experiences of work–family conflict. Based on theories relating social support to stress, a framework for considering how school support affects work–family conflict is proposed and tested. Parent experiences of instrumental support (school schedules, school service provision, and staff accessibility) and school demands on parents (volunteer and homework involvement) were investigated in relation to levels of work–family conflict. Work demands were related to both family-interference-with-work and work-interference-with family; family demands related only to time-based family-interference-with-work. Perceptions of school scheduling as supportive were related negatively to both time- and strain-based work-interference-with family, whereas perceptions of school transportation services were related to both time- and strain-based family-interference-with-work. No buffering effects of these types of support were found. Implications for how community organizations can play a role in ameliorating work–family conflict are discussed.  相似文献

Reflexivity in qualitative and ethnographic social science research can provide a rich source of data, especially regarding the affective, performative and relational aspects of interviews with research subjects. This paper explores by means of three case examples different ways of accessing and using such reflexivity. The examples are drawn from an empirical psycho-social study into the identity transitions of first-time mothers in an inner-city multicultural environment. Fieldnotes and supervision were used to engage with researcher subjectivity, to enhance the productive use of reflexivity and to address the emotional work of research. The methodology of the supervision was psychoanalytic, in its use of a boundaried frame and of psychoanalytic forms of noticing oneself, of staying engaged emotionally as well as creating a reflective distance. The examples illustrate how this can enhance the knowledge gained about the research subjects.  相似文献

In this paper we revisit the concept of brokerage in social networks. We elaborate on the concept of brokerage as a process, identifying three distinct classes of brokerage behavior. Based on this process model, we develop a framework for measuring brokerage opportunities in dynamic relational data. Using data on emergent inter-organizational collaborations, we employ the dynamic brokerage framework to examine the relationship between organizational attributes and coordination in the evolving network. Comparing the findings of our process-based definition with traditional, static approaches, we identify important dimensions of organizational action that would be missed by the latter approach.  相似文献

Abstract

Objective: The objective was to survey community college personnel about student substance use, and infrastructure (staff and funding), programs, and collaborations dedicated to substance use prevention. Participants: The sample included 100 administrators, faculty, and health services staff at 100 community colleges. Methods: Participants completed a Web-based survey. Results: Participants reported a number of alcohol and other drug (AOD) related concerns. Despite limited staff and funding dedicated to AOD, institutions are implementing a number of programs, although many are not implementing some of the programs popular at traditional 4-year colleges. They are also collaborating with a number of on- and off-campus groups. The availability of staff and funding dedicated to AOD, and the presence of residence halls, is associated with health programming and substance abuse collaborations. Conclusions: Results suggest that there is a need for increased research to understand the most effective AOD prevention strategies for community colleges.  相似文献
