The uncovered set in spatial voting games

In a majority rule voting game, the uncovered set is the set of alternatives each of which can defeat every other alternative in the space either directly or indirectly at one remove. Research has suggested that outcomes under most reasonable agenda processes (both sincere and sophisticated) will be confined to the uncovered set. Most research on the uncovered set has been done in the context of voting games with a finite number of alternatives and relatively little is known about the properties of the uncovered set in spatial voting games.We examine the geometry of the uncovered set in spatial voting games and the geometry of two important subsets of the uncovered set, the Banks set and the Schattschneider set. In particular, we find both general upper and lower limits on the size of the uncovered set, and we give the exact bounds of the uncovered set for situations with three voters. For situations with three voters, we show that the Banks set is identical to the uncovered set.     

从胡文化“汉化”看生态环境的迁移对文化转型的影响

不同文化特质的形成 ,除受政治经济影响外 ,还受特定生态环境的制约。胡汉两大文化体系的差异 ,在很大程度上就是不同生态环境作用的结果。与此相应 ,文化的发展一旦脱离了与自身相适应的环境 ,就势必要出现势能上的劣势 ,并逐渐与异地文化相溶

Health Care during Transition and Health Systems Reform: Evidence from the Poorest CIS Countries

The poorest seven countries of the former Soviet Union (CIS‐7) moved from a centralized system of health‐care funding and delivery to a range of institutional and financial arrangements. The different paths chosen have implied different results in terms of available resources, internal efficiency, health‐care inequality, and the corresponding incidence of public expenditures. This paper examines the level, composition and allocation of public spending on health, in light of the evolution of the health systems during the transition. The financial constraints experienced by CIS‐7 countries were reflected in the decrease of health‐care quality, the collapse of the already inefficient public health activities, and the increased incidence of out‐of‐pocket expenditures. These factors, alongside the increase in poverty, resulted in a decrease in health‐care utilization, suggesting that these countries may experience difficulties in achieving the health‐related Millennium Development Goals.     

Enabling Adults with Learning Disabilities to Articulate their Housing Needs

Correspondence to Dr Alex McGlaughlin, Department of Social Sciences, The Nottingham Trent University, Burton Street, Nottingham NG1 4BU, UK. E-mail: alex.mcglaughlin{at} ntu.ac.uk Summary This study is about involving adults with learning disabilitiesin service planning by asking them to articulate their own needsin relation to housing. It also identifies some of the barriersto meeting the housing needs of this group. The views expressedindicate that ordinary housing with small numbers is the preference,and that appropriate support is highly valued. This suggestsa need for housing of a supported living model or similar. Theservice users in this study were clearly able to verbalize theirpreferences as well as to think through potential options. However,there is also clear evidence that they feel powerless in makingchoices, with decisions being taken on their behalf by professionalsand carers. This demonstrates the need for a cultural shiftwhereby the voices of adults with learning disabilities areheard and acted upon.     

“十五”时期西藏经济运行特点及2006年趋势分析

定量与定性分析结果表明,“十五”时期西藏经济运行特点明显:高位运行但仍有较大增长潜力;资本投入、第三产业是经济增长的决定性因素,而技术进步的贡献率大幅下降,工业还没能成为有力的增长点;固定资产形成的拉动力量增大,居民消费贡献稳定;区域经济呈现新格局,城镇在经济集聚中作用日益突出。还存在增长方式粗放,效率较低;培育自我发展能力进展缓慢;需求结构失调,农牧民消费乏力,社会投资仍未启动等问题。文章预测了2006年经济运行趋势,提出以市场为导向推进产业结构调整,扩大最终需求,提高科技水平,加速培育区域经济新格局等政策建议。     

Assessing Fitness to Practise and Managing Work‐based Placement

This article describes the experience of Nottingham and Birmingham Universities in partnership with workers from Advocacy In Action and shows that service‐users, carers and other eligible citizens can and should be involved in deciding fitness for practice and in the managing of that practice, and that such involvement enhances the student experience and lays the foundations for partnership working in the professional arena. The users and citizen stakeholders of social services are a valuable resource in respect of all aspects of service planning, delivery and control. In respect of social work education, their involvement is too valuable an opportunity to miss and we look forward to further exciting partnerships in the field of practice learning.
