The laws of large numbers for Pareto-type random variables with infinite means

In this paper, we consider the laws of large numbers for NSD random variables satisfying Pareto-type distributions with infinite means. Based on the Pareto-Zipf distributions, some weak laws of large numbers for weighted sums of NSD random variables are obtained. Meanwhile, we show that a weak law for Pareto-Zipf distributions cannot be extended to a strong law. Furthermore, based on the two tailed Pareto distribution, a strong law of large numbers for weighed NSD random variables is presented. Our results extend the corresponding earlier ones.     

A comparative study of confidence intervals to assess biosimilarity from analytical data

Assessment of analytical similarity of tier 1 quality attributes is based on a set of hypotheses that tests the mean difference of reference and test products against a margin adjusted for standard deviation of the reference product. Thus, proper assessment of the biosimilarity hypothesis requires statistical tests that account for the uncertainty associated with the estimations of the mean differences and the standard deviation of the reference product. Recently, a linear reformulation of the biosimilarity hypothesis has been proposed, which facilitates development and implementation of statistical tests. These statistical tests account for the uncertainty in the estimation process of all the unknown parameters. In this paper, we survey methods for constructing confidence intervals for testing the linearized reformulation of the biosimilarity hypothesis and also compare the performance of the methods. We discuss test procedures using confidence intervals to make possible comparison among recently developed methods as well as other previously developed methods that have not been applied for demonstrating analytical similarity. A computer simulation study was conducted to compare the performance of the methods based on the ability to maintain the test size and power, as well as computational complexity. We demonstrate the methods using two example applications. At the end, we make recommendations concerning the use of the methods.     

Underlying processes of SCCT: Mediating roles of preventability,blame, and trust

Despite the prevalence of the situational crisis communication theory (SCCT; Coombs, 2007) in crisis communication research, few SCCT-based studies have examined how different crisis types affect post-crisis reputation. This study, therefore, attempts to uncover the underlying processes of SCCT. Specifically, this study examined preventability, blame, and trust as potential mediators of crisis type and organizational post-crisis reputation. A between-subjects experimental study (crisis type: victim vs. accidental vs. preventable) was conducted with 329 college students. The results revealed that crisis type had no direct effects on reputation, but it did affect preventability, blame, and trust. More significantly, the results showed that crisis type indirectly affected reputation in two distinct ways: (1) via a sequence of preventability and blame and (2) via trust. The study includes a discussion of theoretical and practical implications.     

需求取向社区贫困家庭志愿服务的探索

贫困救助是我国社会服务的永恒主题,城市最低生活保障制度和农村五保制度为解决贫困问题提供了制度保障。但是,贫困是一个复杂的持续性的社会问题,社会保障政策的公共性与弹性要求以及社会的不断变迁,使得贫困救助需求的差异性和变化性难以得到有效满足。社区志愿服务以其贴近居民生活的服务特点,可以有效地填补社会救助政策的漏洞。本文描述了社区贫困家庭的现状及其特点,揭示了当前社区服务和社会政策存在的缝隙;立足社区贫困家庭的需要,提出了社区贫困家庭志愿服务应该提供的主要服务内容,寄望建设一个符合中国社会文化情境和具体家庭需求的社区贫困家庭志愿服务。

课堂提问与大学生思辨能力培养

研究采用问卷和访谈形式调查职前英语教师是否有在课堂提问中培养学生思辨能力的意识。调查结果显示:职前教师的提问以理解课文为主要目的;绝大多数问题是不鼓励学生思考的低度认知问题,不利于培养学生的思辨能力。职前教师课堂提问存在着理论与实践的矛盾。他们认为在英语课堂上培养学生思辨能力的最大障碍是考试制度。     

家庭保障在我国农村社会保障中的地位和作用研究

家庭是人类自古以来形成的最基本的社会生活单位,在中国的历史长河中始终扮演着十分重要的角色,尤其在保障家庭成员的养老、医疗、生育、精神慰籍等方面以及对于社会的安定和发展方面都发挥了十分重要的作用。在目前社会保障制度化发展过程中,家庭保障也对正式的社会保障制度起到了重要的补充作用,在建立和完善农村社会保障体系过程中,其地位和作用更是值得重视。     

行政诉讼类型界说

行政诉讼类型是依照一定标准对人民法院审理具体行政行为的活动进行归类而形成的诉讼形态。它具有内容的概括性、划分标准的多样性及与诉讼活动联系的密切性三个特征。它与刑事诉讼类型、民事诉讼类型、行政诉讼模式、行政诉讼请求、行政判决有一定的联系与区别，在本质上体现了对行政相对人的权利救济。     

中国传统四合院建筑的发生机制

从原始社会文化遗址发掘的考古资料入手,通过对居住建筑布局演变过程的阐述,揭示出传统四合院建筑格局的发生机制不是封建礼制下的伦理序位,而是抽象化的人体图式;提出如果从人体图式是中国传统四合院建筑发生机制的观点出发,那么可对四合院建筑的形式、布局、称谓以及文化内涵等方面做出比较合理和完整的阐释。
