浅议后勤工作的新内涵

后勤工作是体现党的“立党为公,执政为民”政策思想的前沿阵地,是考查“科学执政、民主执政和依法执政”水平的敏感基地,是构建社会主义和谐社会、建立和谐校园的服务场地,只有对后勤工作内涵认识有所提高,才会进一步把后勤工作沿着政治文明的轨道推向一个新的阶段。     

Combining answers to direct and indirect questions: An implementation of Kuk’s randomized response model

Abstract

In this article, we propose a two folded approach for estimation of the population proportion of a sensitive attribute. The rationale of proposed technique is to give respondents choice if they want to avail randomized device or not. Thus, our technique is inherently capable of entertaining the responses attained through direct questioning and by employing randomization device, as well. We believe that free to choose policy will be helpful to develop a curtsy between interviewer and respondent (which is highly desirable, especially when sensitive issue is under consideration) and thus enhances the survey reliability. The proposed technique is developed for simple random sampling, at first, and then extended to stratified random sampling. The superior performance of proposed technique in comparison to the Kuk (1990 Kuk, A. Y. 1990. Asking sensitive questions indirectly. Biometrika 77 (2):436–8. doi:10.1093/biomet/77.2.436.[Crossref], [Web of Science ®] , [Google Scholar]) method is demonstrated throughout this article. We provide algebraic, graphical and numerical evidences in support of our proposed technique. Furthermore, we also offer cost analysis considering most commonly used cost functions in the literature of survey research.

西部小说:"概念"、"命名"及历史呈现--当代西部小说与西北地域作家群考察之一

从中国现当代历史文化的深处,力图揭示西部小说滋生、衍变的轨迹,对西部小说的"概念"、"命名"作了新的定位.以"四代三时期"划分的清晰轮廓,对西部小说家代际的转换、文学传承以及不同时期内的独自表现,进行了新的阐释.     

马克思关于“人的全面发展”的学说

"人的全面发展学说"在马克思主义理论体系中具有重要的地位,是贯穿马克思主义理论体系的灵魂.充分挖掘马克思关于"人的全面发展"学说的理论内涵,系统论述"人的全面发展"的含义、根据、条件、历史阶段、地位作用等对于今天的改革开放和社会主义现代化建设以及思想政治教育工作具有非常现实的指导意义.     

不同成长阶段下中小企业融资方式选择研究

本文通过实证研究检验了在经济转轨时期我国中小企业的融资行为符合西方成熟国家的金融成长周期理论,即中小企业的融资结构随着中小企业生命成长阶段的不同,其呈现周期变化趋势.同时,发现中小企业权益融资与债务融资的渠道多种多样,不同的发展阶段也必定有不同的来源.最后通过回归分析,对我国中小企业融资方式的选择进行了实证研究.     

供应链柔性批量订货契约研究

为实现批量订货与柔性采购相结合的目标,用一定折扣换取一定的柔性,从而实现供应链内部的协调及风险的分摊。在供应链中,从卖方角度,希望买方以稳定的(最好是不变的)订货量订货,以保证稳定的销售,减小牛鞭效应的影响,为此,卖方将对超过约定订货量的部分商品收取额外费用(或取消价格折扣);另一方面,从买方角度,由于下游不稳定的市场需求,买方希望没有约定订货量的约束,而是根据实际的市场需求在当期确定订货量。双方折中的结果是,买方必须许诺一个基本的订货量,但拥有一定次数和范围的改变订货量的机会。针对这一问题,建立了一种带柔性的批量订货契约模型,并通过仿真验证了模型能够节约订货成本,实现供应链中风险的重新分配。     

南宋官窑分期浅析

本文根据最新的考古资料把南宋官窑(老虎洞窑和郊坛窑)分为两期,其年代的分界线为宋宁宗开禧年间。两期产品在器类、造型、装饰及烧造工艺等方面存在较明显的变化。文章认为两个官窑存在同期共烧的事实。官窑产品不仅用于朝廷的礼仪活动,还可能作为商品进入市场流通。     

解读《麦田里的守望者》的主人公霍尔顿

塞林格凭<麦田里的守望者>一书一举成名,其笔下的主人公霍尔顿是一位非常敏感且具有叛逆精神的青少年.小说中霍尔顿使用的语言具有鲜明的个性色彩,为了使读者深入地更理解小说的内涵,文章就霍尔顿的性格特征进行了分析,阐述了内心充满矛盾的霍尔顿不能与人沟通,逃离学校、逃离家庭、逃离社会,最终走向精神崩溃的心理历程.     

Respondent hazards in the unrelated question randomized response model

The randomized response technique is a method of interviewing which allows estimation of population proportion or mean of a sensitive characteristic while maintaining anonymity of response. This is accomplished by use of two questions in the interview, one sensitive and one not so, with the respondent applying a random device to determine which question to answer. The statistician knows the parameters of the random device but is kept from knowledge of individual outcomes. When the nonsensitive question bears on a matter quite foreign to the sensitive characteristic, it is termed an unrelated question, and the associated technique carries that designation. Critical in the construction of such a model are the assigned probability p that the respondent will select the sensitive question and the proportion Π_y of the population having the unrelated nonsensitive characteristic. The choice of these parameters is discussed herein with reference to the risks perceived by respondents.
