财政扶持政策对西部地区农民参加新农村合作医疗的影响——基于自然实验的研究途径

本文将对西部农民参加新农村合作医疗的财政扶持政策的实施作为一个自然实验,应用微观经济计量方法分析了财政扶持政策对西部农民参加新农村合作医疗的影响。研究结果表明,与2004年相比,2006年西部农民参加新农村合作医疗的概率增加了96.46%,说明针对西部农民参加新农村合作医疗的财政扶持政策作用效果显著。     

埃及“7·3”事件后美国对埃援助政策研究

埃及被认为是美国在中东地区和阿拉伯世界最坚定的盟友。美国自1979年埃及与以色列签署和平协议以来,每年向埃及提供大量的军事与经济援助。2013年7月3日,埃及民选总统穆罕默德·穆尔西被埃及军队废黜。根据联邦法律,美国暂停对埃及的部分援助。本文从“7·3”事件后美国对埃及援助的变化及其特点、影响援助变化的主要原因进行分析,展现美国对埃及援助政策中的复杂利益和战略考量,根据对历史与现实的分析,预测美国今后对埃援助政策的走势。     

Empowered and self-managing users in methadone treatment?

Empowerment is a keyword in treatment. Users should have the means and possibilities to influence their treatment and become self-managing. Drawing on ethnographic fieldwork in a Danish methadone treatment project, we find that the practices of users and staff are often not carried out in accordance with governmental intentions. We identify a gap between the official notions of treatment and practices. We analyse the notions and practices of empowerment by applying two analytical perspectives. First, we apply a constructionist perspective in which empowerment is analysed as wanting to set users ‘free’ but also as ways to govern. We elaborate the analysis by applying a more practice-oriented focus. Drawing on this perspective, we analyse the ways in which staff and users constantly produce, construct and negotiate institutional practices that differ from the governmental intentions for treatment.     

International Organisations and the Politics of Migration

The last two decades have seen major shifts in the way international organisations (IOs) address migration. While state sovereignty remains central in the politics of migration, IOs are increasingly developing their visions regarding how the cross-border movements of people should be governed (or ‘managed’) and, in some cases, they have become important actors in the design and implementation of migration policy. Research on the role and functions of IOs remains scarce, however, and there are major uncertainties, concerning not only their actual influence, but also the political context in which they operate and the outcome of their initiatives. According to their advocates, the involvement of IOs would enable greater international cooperation, which would lead to policies that pay greater attention to human rights and development imperatives. Yet, at times, interventions by IOs seem to reinforce existing imbalances, as these organisations primarily tend to align themselves with the interests and agenda of developed receiving states. In addition, the work of IOs is embedded in a complex institutional setting, characterised by sometimes-problematic institutional relations between them, as well as between IOs and other international cooperation mechanisms.     

The Politics and Discourse of Migrant Return: The Role of UNHCR and IOM in the Governance of Return

This article proposes that there is added value in moving beyond isolated studies of return-related migration policies in order to consider both deportations and so-called assisted voluntary returns under the common heading of ‘state-induced returns’. Based on official documents and interviews with staff members of the United Nations High Commissioner for Refugees and the International Organisation for Migration, it argues that international actors working in the field of migrant return engage in a type of task-sharing that goes beyond functional complementariness. With regard to the return of rejected asylum seekers, for instance, they legitimise each other's engagement as well as the overarching return objectives of governments, and are, therefore, involved in norm-building regarding the acceptability of state-induced returns. In addition to setting certain minimum standards regarding states' treatment of their immigrant population, international actors assist states in upholding control over them. Rather than merely replacing state-led regulation, international actors thus support domestic governments in reaching their migration control objectives, and thereby contribute to a stabilisation of state sovereignty in the governance of migration.     

日本政府钓鱼岛事件对策的演变及其原因

20世纪70年代以来,日本政府的钓鱼岛事件对策,虽基本立场未有微动,但在具体方式上却经历了从政治处理、政治和司法二元处理到司法处理的转换。这种转换之所以可视为有其必然性,主要在于日方对钓鱼岛事件在对华关系格局中的定位和成为决定事件处理方针制约要素的日本政治及国际政治的状况已发生重大变化。     

论公共政策效能的衰减机制

公共政策效能衰减分为有效衰减和无效衰减两种形式。公共政策效能有效衰减是公共政策效能运行规律的反映,而无效衰减是在公共政策效能没有正常释放的情况下发生的,是影响公共政策目标实现的主要因素。公共政策共同体中,不同行为主体之间行为取向的多元化和行为方式的分散化是公共政策效能无效衰减的主要原因。公共政策共同体中各行为主体以理解为目的的交往活动,是减少公共政策效能无效衰减的重要途径。现有制度设计上的不完善,导致公共权力一定程度上的垄断化、碎片化和异质化,这是造成公共政策效能无效衰减的根本的原因。打造有利于公共政策共同体中各行为主体在平等互动基础上的有效的和全方位、深层次交往的制度性平台,实现公共权力在组织上、资源上和功能上的整合是克服公共政策效能无效衰减的根本途径。     

STOCHASTIC COST-VOLUME-PROFIT ANALYSIS IN A COMPETITIVE OLIGOPOLY

Previous stochastic cost-volume-profit (CVP) models have assumed that the firm was operating under either perfect competition or monopolistic conditions. This paper presents a stochastic CVP model applicable to oligopolistic competition. Each firm is assumed to maximize a linear function of the expected value and the standard deviation of its random profits. The result is a game-theoretic model that is solved using the concept of a Nash equilibrium. The results of the model are used to examine a firm's competitive strength. The model can be easily modified to accommodate a measure of risk based on the capital asset pricing theory.     

A LOWER BOUND FOR THE SINGLE-LEVEL DYNAMIC HORIZON LOT-SIZING PROBLEM

Conventional production planning methods assume the existence of a medium- or longrange demand horizon. However, demand usually is known over a much shorter range; scheduling decisions must be made within this “decision window,” which rolls forward in time. This paper presents a new lower bound for lot-sizing heuristics in a rolling-horizon framework and compares it to the well-known Wagner-Whitin bound. The new bound indicates heuristic schedules that have costs close to the optimum. Rolling-horizon schedule costs are compared to corresponding static-horizon schedule costs (assuming the whole horizon is known in advance), using the ratio of decision-window size to the natural order cycle as a parameter. For values below unity, the rolling-horizon policy is significantly more costly. For values above one, the two policies have similar costs and actually converge as the parameter value increases.     

“世界政策”视野下的德国对华文化政策

德国对华文化政策的出现是同德国的“世界政策”紧密结合在一起的,在武力侵华过程中,德国殖民者便认识到了通过文化手段对中国施加影响的重要性.摩洛哥危机的爆发更坚定了德国统治者推行对外文化政策的决心,他们把中国选取为推行这一政策的首要目标.至第一次世界大战爆发前夕,德国推行对华文化政策的中心机构已经形成.
