Games With Discontinuous Payoffs: A Strengthening of Reny's Existence Theorem

We provide a pure Nash equilibrium existence theorem for games with discontinuous payoffs whose hypotheses are in a number of ways weaker than those of the theorem of Reny (1999). In comparison with Reny's argument, our proof is brief. Our result subsumes a prior existence result of Reny (1999) that is not covered by his theorem. We use the main result to prove the existence of pure Nash equilibrium in a class of finite games in which agents' pure strategies are subsets of a given set, and in turn use this to prove the existence of stable configurations for games, similar to those used by Schelling (1971, 1972) to study residential segregation, in which agents choose locations.     

河北省新民居建设现状及农民认知调查研究

以唐山市和秦皇岛市等地新民居建设为调研对象,采用访谈法、问卷调查法和描述性统计法,对河北省新民居建设现状及农民认知评价进行分析研究。结果表明,农民对已建成新民居带来的实惠满意度较高,而在新民居建设宣传、在建率和施工单位资质及农民对新居民建设认知度等方面还存在不同程度问题。     

关于运输毒品罪若干问题研究

运输毒品罪是一种严重的毒品犯罪,由于这一犯罪与其他毒品犯罪既有密切的关联性又具有自身的特殊性,因此在司法实践中不仅应注意把握其构成特征,而且应弄清其罪与非罪、此罪与彼罪的界限。     

基层权力运作的逻辑:上海社区实地研究

摘要：城市社区具有自身独特的权力运作逻辑,这一逻辑存在于行动者之间的互动过程之中。本研究选择居民委员会作为切入点,通过考察居委书记、居委委员、居委干事与其他组织的成员、居民区积极分子、普通居民以及某些特殊群体之间的互动过程,对城市社区权力运作或互动过程及其背后的逻辑展开分析。研究发现,在与不同群体的交往过程中,居委会工作者展示出了多种形态的权力,包括人情交往的权力、半科层化的权力、资源交换的权力、组织合作的权力和各种策略性的权力等,并最终概括出城市社区权力运作的五种逻辑,即依附逻辑、协商合作逻辑、精英主导逻辑、人情逻辑和服务交换逻辑。     

农村宅基地流转的制度创新——以“联众模式”为例

在现有制度约束下,＂联众模式＂是一种农村宅基地使用权流转的诱致性制度创新,它推进了农村土地资源、社会资源、劳动力资源的优化配置,满足了新农村建设的要求,实现了有关利益相关方的双赢。农村宅基地使用权流转创新是诱致性制度创新结果,但农村宅基地使用权流转最终需走复合式制度变迁路径。     

试论市场经济成熟条件下商品流通渠道功能的变异

在市场经济发育和成长的不同阶段,商品流通渠道的功能将随着渠道组织结构、渠道管理水平、消费方式、渠道设施、信息技术等因素的变化而出现变异。在市场经济初级阶段,流通渠道的基本功能就是连接生产与消费,促成商品销售,实现商品价值。在市场经济的完善和成熟阶段,流通渠道将越来越多地引导生产和消费,通过商流、物流、信息流的传导与组织,挖掘和创造商品的新价值,提升原有商品的价值,从而使"渠道价值"越来越大。本文主要论述渠道功能在不同阶段的差异及表现。     

针对不同类型销售商的长期激励合同设计研究

在制造商雇用销售商销售产品的过程中,双方之间常常存在关于销售商销售能力和销售努力的不对称信息,制造商需要通过设定合同来激励销售商付出实现制造商利润最大化的销售努力。本文建立了信息不对称情况下,制造商在两周期的长期合同设计并同时制定产品价格的模型。虽然不对称信息存在时,制造商在单周期的最优合同策略是分离策略,而本文的两周期模型结果表明,长期合同中第一个周期的最优合同策略并不一定是分离策略,有可能是混同策略,这与第二周期的折现因子有关。而两周期产品价格也与单周期不同,其大于单周期采取混同策略时的价格,小于单周期采取分离策略时的价格。     

Therapeutic residential care in Spain. Population treated and therapeutic coverage

Therapeutic residential care (TRC) is the name given to specialized children's homes for treating cases with severe emotional and behavioural problems that have been placed in residential care. A recent international review has revealed great diversity in the referral criteria of cases and in the models of intervention carried out. The goal of this study is to describe the population treated in these types of facilities in Spain and the therapeutic coverage given. The sample is made up of 215 young people in children's homes, of whom 93 are in TRC. The cases referred to TRC have been in residential care for less time but have gone through a greater number of placements. These young people also exhibit more problems of drug use, and there is a larger percentage of clinical‐range cases in the Child Behaviour Checklist scales of attention problems and aggressive behaviour. Nevertheless, the results of logistic regression indicate that the only variables that significantly increase the probability of being referred to TRC are drug use and changes of care placements. With regard to therapeutic care, there is a higher percentage in the TRC group receiving psychiatric care, and the sessions are also more frequent.     

生计资产异质性视角下浙江农户宅基地流转后的福利评价与比较徐建军

以浙江宁波、绍兴、嘉兴、湖州等地农户为调查对象,依据农户生计资产分类,就农户宅基地流转后的福利水平进行模糊评价。整体来看,农户经济、居住条件、休闲健康方面的福利水平高于设定的宅基地流转前农户福利的模糊状态,而社会保障、生态环境、发展机会以及心理认同四方面的福利水平在宅基地流转后反而下降了。基于生计资产异质性农户的比较发现,农户经济、居住条件方面均提高了生计资产缺乏型和富裕型农户的福利水平,但降低了这两类农户的社会保障和生态环境方面的福利;不同之处在于,宅基地流转还促进了资产缺乏型农户的休闲健康、发展机遇方面的福利,但降低了其心理认同度,这与宅基地流转对生计资产富裕型农户的影响正好相反。     

Elder Abuse in Residential Settings in Sweden

ABSTRACT

To investigate frequencies and types of elder abuse occurring in residential settings in two municipal areas of Sweden, nursing staff were asked to answer a questionnaire; 499 responded. The findings indicated that elder abuse involving the staff did occur. Eleven percent of the staff knew of situations of elder abuse and two percent admitted that they themselves had been abusive towards an elderly resident. Psychological and physical abuse related to caring activities were most common. In the specific situations reported, the abusers were mostly characterised as hot-tempered, exhausted, and burned out. The abused people were often mentally and/or physically handicapped and generally over 80 years old. Feelings such as powerlessness, anger towards the abuser, and compassion for the abused person were reported. To cope with the situation, they talked to each other or to the manager. They recommended more education and support as the main preventive strategy.
