纳米比亚的土地和生物管理模式

飞机一进入非洲南部国家纳米比亚的首都温德和克，就像进入了一个自然保护区。由于温德和克位于中央高原上，并且以阿瓦斯山脉为天然屏障，游客一进入该市就能问或看见捻角羚和其他羚羊，这不是什么稀罕事。     

Simultaneous choice of time points and the block design in the growth curve model

The aim of this paper is to consider the optimality in the growth curve model with respect to two aspects: time and the block design and to show some relations between information functions for different designs. The A-, D- and E- optimality are studied.     

Five-Hundred Life-Saving Interventions and Their Cost-Effectiveness

We gathered information on the cost-effectiveness of life-saving interventions in the United States from publicly available economic analyses. "Life-saving interventions" were defined as any behavioral and/or technological strategy that reduces the probability of premature death among a specified target population. We defined cost-effectiveness as the net resource costs of an intervention per year of life saved. To improve the comparability of cost-effectiveness ratios arrived at with diverse methods, we established fixed definitional goals and revised published estimates, when necessary and feasible, to meet these goals. The 587 interventions identified ranged from those that save more resources than they cost, to those costing more than 10 billion dollars per year of life saved. Overall, the median intervention costs $42,000 per life-year saved. The median medical intervention costs $19,000/life-year; injury reduction $48,000/life-year; and toxin control $2,800,000/life-year. Cost/life-year ratios and bibliographic references for more than 500 life-saving interventions are provided.     

Area-based partnerships in rural Poland: The post-accession experience

The paper examines the characteristics of area-based partnerships in rural Poland. It is based on the study of partnerships created after the accession to the European Union in 2004. Partnership structures have been rapidly adopted in rural Poland due to opportunities provided by the LEADER+ Pilot Programme. However, the research showed that partnerships are frequently subject to elite domination by local authorities and hence fail to fully engage a range of community and private sector actors. Funding rules for LEADER, most notably the condition that money will only be paid on the completion of projects, has been particularly significant in perpetuating the domination of partnerships by organisations with existing access to financial and human capital. Hence funding arrangements can undermine the ability of Polish partnerships to operate in ways which harness the endogenous capacities of local communities. To date power differentials between notional ‘partners’ have been experienced to a greater extent than in advanced liberal democracies. The research found that overt domination of partnership structures by state agencies limited the possibilities for community led development initiative in rural Poland.     

The operation and subversion of gendered war discourses: soldierhood,motherhood and military dissent in the public production of Kimberly Rivera

This article undertakes a discourse analysis of texts concerning a recent high profile case of opposition to war by Kimberly Rivera, a US soldier and a mother of five. Developing on previous research concerning how female soldiers, anti-war women and anti-war soldiers have been made intelligible within understandings of war and gender, the analysis traces the discursive repertoires constituting Rivera as a political subject. The article considers how, when and with what implications for broader discourses of gender and war, and their transformation, the categories of soldierhood and motherhood were invoked to construct and obstruct Rivera as an intelligible dissenting subject. The most common presentation of Rivera centered on her motherhood, understood to be in crisis due to her military role. With motherhood and soldierhood seen to be antithetical this crisis could be “solved” through opposition to war. This limited the extent to which Rivera was intelligible as a “thinking citizen” and reproduced motherhood and soldierhood as stable categories leaving their immanent discourses concerning war and gender untroubled. The article then considers ways in which alternative avenues for transformative interventions could open up if dissenters like Rivera were “written” as other than fundamentally contradictory figures.     

Making connections: Severe mental illness and closeness with other people

Much has been written about social lives of people with severe mental illness (SMI). Before social lives can flourish, however, people with SMI must first get close to other people. We studied this closeness by holding three hour-long focus groups at Fountain House, a community mental health agency in New York City. We found that closeness between two people with SMI is challenging because someone with depression, for example, may have trouble understanding someone with a different disorder (e.g., schizophrenia). Romantically, closeness is also challenging—SMI is hard to explain to partners. In the workplace, closeness is difficult because SMI can alienate co-workers. It could push them away. In mental health programs, we found that closeness has more of a chance to develop (1) during evening and weekend activities; (2) when activities are planned often enough to prevent isolation; and (3) when staff reach out to people before extended absence causes distance.     

Children and the Modern Farming Movement

In the twenty‐first century, a small percentage of U.S. children have ties to family‐based agriculture. Yet with the rise of the modern farming movement that emphasizes local and family‐based production, new spaces may exist for involving children and youth in farming. This article focuses on the social value of children to family‐based agriculture in the contemporary era. Drawing on a qualitative study of families that farm in the capital region of New York—an epicenter for the modern food movement—we consider why families farm, how they involve children in their farms, and how they understand children's contributions. Interviews with 76 adult members of 50 families show children to be central to families' goals; they often rationalize farming as a lifestyle choice undertaken for the benefit of their children. Families also actively involve their own children—and other people's children—in their farms. By documenting the way families talk about children and farming, we shed light on the logic used to incorporate children into modern productive enterprises. The centrality of children, we argue, helps explain the success of the modern food movement and the persistence of family‐based agriculture despite conditions that make it economically difficult to accomplish.
