耐力运动对大鼠血液学指标影响的实验研究

通过测定大鼠4周耐力运动后RBC、Hb、MCT、MCV的变化，并观察大鼠一般表现，结果：4周耐力运动后大鼠RBC显减少（P＜0．05），Hb下降（P＜0．05），表明本实验采用的运动形式和运动负荷量能造成大鼠运动性贫血，可作为研究运动性贫血的动物模型。     

A New Pearson-Type QMLE for Conditionally Heteroscedastic Models

This article proposes a novel Pearson-type quasi-maximum likelihood estimator (QMLE) of GARCH(p, q) models. Unlike the existing Gaussian QMLE, Laplacian QMLE, generalized non-Gaussian QMLE, or LAD estimator, our Pearsonian QMLE (PQMLE) captures not just the heavy-tailed but also the skewed innovations. Under strict stationarity and some weak moment conditions, the strong consistency and asymptotic normality of the PQMLE are obtained. With no further efforts, the PQMLE can be applied to other conditionally heteroscedastic models. A simulation study is carried out to assess the performance of the PQMLE. Two applications to four major stock indexes and two exchange rates further highlight the importance of our new method. Heavy-tailed and skewed innovations are often observed together in practice, and the PQMLE now gives us a systematic way to capture these two coexisting features.     

财政科技投入产出绩效评价指标的选择

财政科技投入产出绩效评价体系的构造过程可分为评价指标初选和指标体系完善两个阶段,在评价指标初选阶段主要使用定性分析方法,在指标体系完善阶段主要使用定量方法。结合上海市的问卷调查资料,构建出财政科技投入产出绩效评价体系,以期给实践工作带来启发和帮助。     

社会系统的矛盾与和谐

基于马克思历史唯物主义社会模型,广泛吸收系统科学成果,建立"社会系统的新模型",并在这个新模型上讨论社会系统矛盾与和谐的辩证关系。提出"社会和谐"的三种定义,并指出"社会系统和谐指数"以及社会学数学化的研究方向。联系实际,讨论中国"和谐社会建设"的五个重大问题。     

面向服务组合的服务语义匹配机制

为提高服务组合中服务匹配速度和正确率,提出了基于服务索引的服务语义匹配机制。在面向独立服务匹配算法基础上,引入服务索引机制,提出面向服务组合的语义匹配算法,并在算法中加入了对服务输入/输出匹配的可用性分析。为进一步提高服务匹配的精确性,引入了语义匹配度概念,以实现具有多种匹配值的服务类别语义匹配,继而给出综合语义匹配值的计算方法。实验分析表明基于服务索引的语义匹配能有效地提高服务匹配效率。     

Groups and individuals: conformity and diversity in the performance of gendered identities

The nature and role of social groups is a central tension in sociology. On the one hand, the idea of a group enables sociologists to locate and describe individuals in terms of characteristics that are shared with others. On the other, emphasizing the fluidity of categories such as gender or ethnicity undermines their legitimacy as ways of classifying people and, by extension, the legitimacy of categorization as a goal of sociological research. In this paper, we use a new research method known as the Imitation Game to defend the social group as a sociological concept. We show that, despite the diversity of practices that may be consistent with self‐identified membership of a group, there are also shared normative expectations – typically narrower in nature than the diversity displayed by individual group members – that shape the ways in which category membership can be discussed with, and performed to, others. Two claims follow from this. First, the Imitation Game provides a way of simultaneously revealing both the diversity and ‘groupishness’ of social groups. Second, that the social group, in the quasi‐Durkheimian sense of something that transcends the individual, remains an important concept for sociology.     

中国女排与世界优秀女排非技术指标对比分析

利用文献资料法、数理统计法、比较分析法,对参加2013世界女排大奖赛的中国女排和巴西、塞尔维亚、日本、意大利、美国五个队非技术指标对比分析,旨在研究分析新奥运会周期中外优秀女排非技术因素的差异,探讨中国女排非技术指标的现状,为新一届国家女排积极备战里约奥运会提供理论参考.     

幸福指数指标体系的构建

经济增长的终极目的是使人民生活得更幸福。但由于过去在评价经济发展时过多的关注GDP等硬数据,而对经济社会的全面发展重视不够,对人民幸福程度这一软指标关注不够,使得虽然经济增长了,但人们的幸福感不但没有随之增长甚至还有所下降。因此,研究幸福指标的经济学意义及幸福指数指标体系的构建,对决策部门制定经济发展政策、出台以人为本的相关人文关怀政策、促进社会全面和谐发展,都具有十分重要的意义。     

中国文化产业区域差异的空间计量分析

基于2004年与2008年文化产业国家标准统计数据,分别利用Theil指数与Moran’s I指数对中国文化产业的区域差异与空间自相关性进行了衡量,并运用空间计量经济模型对要素禀赋、集聚经济与产业政策因素对文化产业区域差异的影响进行了实证检验。研究发现：中国文化产业区域差异明显,呈现东高西低的梯度分布格局,但区域间文化产业发展呈收敛趋势;中国文化产业区域间存在不断增强的正向空间相关性与空间集聚性;要素禀赋、集聚经济与产业政策均能解释文化产业的区域差异;文化产业的空间溢出效应有利于缩小区域间的文化产业差异。     

工人非稳定性意向研究
