Candidates' Ideological Locations,Abstention, and Turnout in U.S. Midterm Senate Elections

Many spatial models of voting suggest that citizens are more likely to abstain when they feel indifferent toward the candidates or alienated from them. In presidential elections, previous research offers evidence that alienation and indifference affect individuals' probabilities of voting. We find evidence that indifference and alienation also affect the decision to vote in midterm Senate elections, a context not previously explored. These individual-level effects imply that candidates' ideological locations should influence aggregate turnout by affecting the proportions of citizens who feel indifferent toward or alienated from the candidates. Our aggregate-level analysis supports this (at least in contests featuring two previous and/or future members of Congress). Our findings underscore the importance of the electoral context for understanding citizen behavior and suggest that elections featuring at least one centrist candidate may be normatively appealing since they stimulate participation.     

天津城市可持续发展：市民文化素质评价及塑造现代市民精神

塑造现代市民文化精神是实现天津城市可持续发展的战略需要。通过评价可知,天津近代以来由于经济的发展和京畿地位的确定,基本形成了重义轻利、勤劳敏思、乐于助人、安于现状的市民精神,但缺乏竞争意识:天津市民的文化素质在世界上仅处于下中等发展水平,这与天津未来国际大都市的地位不相称。因此,天津要从发展经济入手,提高教育水平,加快城市文化建设,建立高品位的城市生态文化体系,利用现代化高科技手段,加速推广文化、科技知识,使天津市民的文化素质尽快达到上中等发达国家水平。     

Interstate Cooperation: The Roles of the State Attorneys General

State attorneys general are major participants in intergovernmentalrelations in the United States. This article presents six modelsthat may explain their interactions with each other and teststhree hypotheses associated with two models. Their interactionscomport with the cooperative and the innovation-diffusion models.Only limited evidence supports the hostility model and its associatedhypothesis. No evidence supports the mercantilist and competitivemodels. The response from only one attorney general suggestedhis actions are based on the benign neglect model. The conclusionis drawn that the cooperative activities of the attorneys generalhave produced a more harmonious federal system in terms of enforcementpolicies.     

人肺癌中TNF-α基因多态性分布的意义及其对细胞凋亡的影响

目的:观察TNF-α基因启动子区-308位核苷酸多态性基因型在肺癌和对照人群中的分布,以及这种多态性对该基因表达和细胞凋亡的影响。方法:PER-RFLP分析112例肺癌和99例正常人的TNF-α基因启动子区-308位核苷酸多态性,TNF-α-308*G等位基因记做TNF-α1,TNF-α-308*A等位基因记做TNF- α2。免疫组织化学方法检测肺癌组织中TNF-α的表达,比较不同基因型肺癌病例的标本之间TNF-α基因表达的差异性。TUNEL法检测肺癌组织中细胞凋亡,并对比分析TNF-α-308位核苷酸多态性及其对肺癌组织中TNF -α表达和不同类型细胞凋亡的影响。结果:肺癌组与对照组的基因型分布为TNF-α1/1(52．7％、46．5％)。 TNF-α1/2(35．7％、48．5％),TNF-α2／2(11．6％、5．1％);等位基因频率为TNF-α1(70．5％、70．7％),TNF- α2(29．5％、29．3％),组间没有显著性差异,P>0．05。两种基因型个体在TNF-α基因表达上,TNF-α2/2基因型个体高于TNF-α1／1基因型的个体,两者差异显著,P<0．01。TNF-α表达的高低与癌细胞凋亡有比较明确的关系,TNF-α表达高的病例,肺癌细胞凋亡也多,与表达低的病例之间有明显差异,P<0．01。TNF-α表达的高低与间质细胞凋亡之间没有明确的关系。间质细胞平均凋亡指数在高、低分化的肺癌中分别为3．4±0．4和 3．1±0．5,组间没有显著性差异,P>0．015;癌细胞的平均凋亡指数在高、低分化的肺癌中分别为2．4±0．3和 1．7±0．4,两组间有显著性差异,P<0．05,,结论:TNF-α-308位核苷酸的多态性基因型在肺癌和正常人中的分布之间没有明显差别,这种多态性可能不是肺癌易感的遗传因素。但这种多态性与该基因的表达有关。TNF-α高表达肺癌细胞凋亡较多,间质细胞凋亡与TNF-α表达的高低变化之间没有明确的关系。在高分化的肺癌中, TNF-α表达较高,癌细胞凋亡也多,TNF-α-308位核苷酸的多态性可能与了肺癌的分化有关。     

On the Nature of Tolerance: Dichotomous or Continuous?*

The purpose of this article is to reconsider the claim made recently by Mondak and Sanders that political tolerance ought to be thought to be a dichotomous rather than continuous variable. Using data from both Russia and the United States, I demonstrate that those Mondak and Sanders regard as uniquely tolerant are most likely no more than people who were given insufficient opportunity to express their intolerance. Even if such a phenomenon of “absolute tolerance” exists (all ideas expressed in all ways are to be tolerated), it is sufficiently rare that few practical implications are indicated for those doing empirical work on political tolerance and intolerance. * I appreciate the valuable comments of Jeffcry Mondak on an earlier version of this paper.     

社会公正的经济、道德和政治之维--当代社会公正问题的三个研究路径

社会公正理论的研究是一个综合性、多学科相融合的研究。道德、经济和政治分别代表了三个相互独立而又相互依赖的研究路径,三者分别体现了公平、效率和整合性的功能。     

司法鉴定若干问题探析

司法鉴定的内涵应界定为:具有法定鉴定资格的人,受司法机关指派或委托, 对诉讼活动中与案件有关的专门技术问题进行审查鉴别、作出科学判断的活动。目前,我国司 法鉴定人制度还需要完善,司法鉴定体制需要从调整公安、检察机关内设鉴定机构,撤消法院 内部鉴定机构,确定鉴定标准和规则,建立鉴定质量保证体系等方面进行改革。
