从治理组织选择理论的角度解读自愿连锁

作为连锁经营的三大组织形态之一的自愿连锁在我国的发展步伐正在加快,中小零售企业将自愿连锁作为应对实力强大的外资零售巨头和突飞猛进的本土大型连锁企业的主要途径。威廉姆森的组织形态选择理论对自愿连锁进行了深入分析,可为我国中小连锁企业发展自愿连锁提供思路与策略选择。     

中国人精子黄递酶Ⅲ型的分布及精斑黄递酶Ⅲ型的检出

应用超薄层聚丙烯酰胺凝胶等电聚焦技术对辽宁地区200例正常人精子黄递酶Ⅲ型(DIA)的分布进行了研究。其基因频率分别为DIA_3~1=0.6850,DIA_3~2=0.2875,DIA_5~3=0.0275。由阴道液、唾液、乳汁及无精子症精液不能判定DIA_3型。室温保存精斑可检出时限为9个月。     

What Drives the Selection of Political Information on Google? Tension Between Ideal Democracy and the Influence of Ranking

The emergence of the Internet has altered how individuals obtain information—this also applies to political information. Search engines have taken over the role of political information gatekeepers, thus becoming key players in democracy. However, surprisingly little is known about the role of search engines in the political information process, that is, whether they represent an opportunity or a threat to democracy. Through an online survey experiment, which mimicked a Google web interface, this study examines how Swiss citizens select political information on a political news event from a Google search results page. Although citizens consider textual cues from snippets, they are more likely to select sources of information from the top of a Google results page, regardless of the source. We discuss these findings from a democratic theory perspective.     

When Killers Become Victims: Diversionary War,Human Rights,and Strategic Target Selection

The diversionary theory largely focuses on the incentives leaders have to use force. However, little attention has been given to the characteristics that make for a good target. We argue that US presidents choose targets that repress human rights since they are the easiest to sell to international and domestic audiences. By targeting repressive states US presidents can justify their use of force by cloaking their motivation in the language of human rights, responding to calls for intervention, pointing to the failure of international actors and institutions to resolve these problems, and building upon emerging norms that allow for intervention in repressive states. Updating US Use of Force data, we empirically test and find support for our hypothesis that presidents target human rights abusers when they face trouble at home. This paper contributes to target selection process by offering a complete theory of diversionary conflict accounting for cost/benefit calculation of presidents. Moreover, we believe that our findings reveal human rights practices’ role in international conflict, as well.     

News Media Use and Political Engagement Among Adolescents: An Analysis of Virtuous Circles Using Panel Data

This study analyzes reinforcing spirals between news media use and two manifestations of political engagement: political interest and participation intention. Drawing on a three-wave panel study among adolescents, we test the Virtuous Circle Thesis (VCT) in both an online and an offline setting, by distinguishing between selection effects and media effects as key ingredients of the VCT. Overall, the findings lend mixed support to the general argument. While the relationship between specific forms of news media use and political interest appears to be driven primarily by selection effects, reciprocal relations were found mainly between television news and participation intention. The VCT assumption of reciprocal influences was supported most clearly when adolescents’ total news media use was considered. Taken together, virtuous circles appeared to operate rather similarly online and offline.     

目前我国宏观调控的目标、重点及其相关政策的选择

近年来我国经济发展的总体态势出现了一些新情况、新问题、政府宏观调控的目标、重点和相关政策也发生了很大变化。针对这种情况，本通过大量的实证分析，阐明了当前我国通货紧缩现象不会持续，结构性失业问题明显突出，经济增长速度必须适度；揭示了我国宏观调控的重点及其主要方面应该放在优化结构上，而不能一味追求扩大需求；系统阐述了与宏观调控目标和重点相配合的有关政策措施的主要内容。     

胡锦涛对社会公平正义的实现路径选择

胡锦涛同志的社会公平正义思想不是从观念到观念,而是基于现实社会经济基础上的一系列切实可行的政策措施,有着明确的现实路径。促进发展、建设和创新制度、树立公正理念、营造社会环境、改善党的领导是胡锦涛同志社会公平正义的实现路径。     

红细胞酸性磷酸酶(EAP)型的分布及血痕EAP的检出

本文应用琼脂糖凝胶电泳法对辽宁地区213例汉族随机献血员的红细胞酸性磷酸酶(EAP)型进行了检测,其基因频率为EAP~(?)=0.169,EAP~b-0.831。结合文献资料分析了EAP型分布的种族差异,指出了各人种EAP型分布的特点。用琼脂糖凝胶电泳法,对红细胞溶血液EAP型的最小检出量为2μL(2×3mm滤纸条)及0.5μL(直接加样);对血痕EAP型的最小检出量为7.5μL血液制成的检样。本法在4℃保存4周以内的红细胞溶血液和室温保存25天的血痕均能正确判定EAP的型别。     

红细胞和血痕酸性磷酸酶(EAP)表型及广东人群EAP基因频率的调查

本文采用薄层聚丙烯酰胺凝胶等电聚焦电泳检测红细胞及血痕酸性磷酸酶表型,并对不同条件下的血痕标本进行检测,发现室温下(15～33℃)保存的110例纱布血痕7周内可全部正确分型,21例磁板血痕9周内均可正确分型;含血量≥5λl 的血痕可被正确检出 EAP 表型;日晒、水洗、发霉等因素可影响血痕 EAP 型的正确检出。同时调查了广东人群的 EAP 表型分布,基因频率为 p~a=0. 2338,p~b=0. 7662,发现 EAP 基因频率分布存在着地区差异。     

The effects of base rate and cutoff point choice on commonly used measures of association and accuracy in recidivism research

Several measures of association and accuracy commonly used in the recidivism literature are examined for their sensitivity to variations in the proportion observed to recidivate (the base rate) and in the proportion selected for classification as recidivists (selection ratio). Logistic regression models are employed on a sample of 11,749 convicted offenders to generate predicted probabilities of four recidivism criteria varying in base rates from 0.06 to 0.48. Cutoff point selections from 0.1 to 0.9 show the effects of cutoff point changes on the following commonly used measures of association and accuracy: RIOC (relative improvement over chance), MCR (mean cost rating), Φ, γ, PRE (proportion reduction in error), and percentage correct. While all these statistics vary across base rate and cutoff points, some vary more than others: RIOC varies across cutoff points more than MCR, MCR more than Φ, and Φ more than γ. Researchers comparing such statistics across studies need be wary of the dangers of ignoring such variation.
