长爪沙鼠颌下腺免疫球蛋白A的定位分布   总被引:1,自引:0,他引:1  
采用免疫组织化学方法对不同日龄的长爪沙鼠颌下腺IgA的定位分布进行了研究。结果表明,长爪沙鼠的颌下腺由导管部和分泌部构成,分泌部主要由浆液腺构成,导管部包括闰管、纹管、颗粒曲管和小叶间导管等。DAB显色结果表明,IgA阳性细胞主要分布于浆液性腺泡、闰管、纹管、颗粒曲管和小叶间导管,并可分布于腺泡和腺管间结缔组织,IgA阳性产物的分布具有不均一性,无明显随年龄变化的规律性。阳性产物分布于胞质中,胞核呈阴性,对照组阴性。提示从浆细胞产生或循环而来的IgA先经结缔组织进入颌下腺组织,进而定位分布于浆液腺泡和各级导管,导管部有较多的IgA分布。  相似文献

The present study was designed to examine effects of closed-circuit technology on children's testimony and jurors' perceptions of child witnesses. For the study, a series of elaborately staged mock trials was held. First, 5- to 6-year-old and 8- to 9-year-old children individually participated in a play session with an unfamiliar male confederate. Approximately 2 weeks later, children individually testified about the event at a downtown city courtroom. Mock juries composed of community recruits viewed the trials, with the child's testimony presented either live in open court or over closed-circuit television. Mock jurors made ratings concerning the child witness and the defendant, and deliberated to reach a verdict. Results indicated that overall, older children were more accurate witnesses than younger children. However, older, not younger children produced more inaccurate information in free recall. Compared to live testimony in open court, use of closed-circuit technology led to decreased suggestibility for younger children. Testifying in open court was also associated with children experiencing greater pretrial anxiety. Closed-circuit technology did not diminish factfinders' abilities to discriminate accurate from inaccurate child testimony, nor did it directly bias jurors against the defendant. However, closed-circuit testimony biased jurors against child witnesses. Moreover, jurors tended to base their impressions of witness credibility on perceived confidence and consistency. Implications for the use of closed- circuit technology when children testify are discussed.  相似文献

The increase in the use of self-managing work teams in organizations has been accompanied by growing employee resistance and concern about what such dramatic changes mean to workers. Using an organizational justice perspective, this chapter identifies and examines employee concerns about the move to self-managing work teams in two Fortune 500 organizations. Employee fairness concerns regarding three types of justice—distributive, procedural, and interactional—are highlighted. Findings suggest that to address employee fairness concerns regarding the move to self-managing work teams, managers should act distributively, procedurally, and interactionally justly.[Self-managing work teams are] the right way and the only way to be productive.—Self-managing work team member in a Fortune 500 company  相似文献

We estimate the causal effect of prison conditions on recidivismrates by exploiting a discontinuity in the assignment of federalprisoners to security levels. Inmates housed in higher securitylevels are no less likely to recidivate than those housed inminimum security; if anything, our estimates suggest that harsherprison conditions lead to more post-release crime. Though smallsample sizes limit the precision of our estimates, we arguethat our findings may have important implications for prisonpolicy, and that our methodology is likely to be applicablebeyond the particular context we study.  相似文献

法律全球化     
提到法律全球化,我们可能联想到整个世界生活在单一法律规则下的程度。基于全球合意或者由于全球所有组成部分的平行发展而形成,这种单一法律规则可能由单一的强制执行角色付诸实施。尽管两极世界和冷战的结束带来些许欣慰,但我们并没有过多移近国际法体制,无论是通过确立单一全球法律提供者和实施者,还是通过坚强有力的民族国家协商一致。如果我们已经有的话,我们会说国际法,而不是法律全球化。我们甚至也不能信心十足地说,法律已经全球化或普遍化,具体表现是不管他/她走到地球的什么地方,人际关系均被一定的法、即使不是各处都相同的法律…  相似文献

Interactional fairness judgments: The influence of causal accounts   总被引:5,自引:1,他引:5  
There has been an increasing amount of research conducted on issues of procedural justice. Although this research has demonstrated that the type of procedure used to allocate outcomes has an independent influence on people's judgments of the fairness of a decision, there is growing empirical evidence that such judgments are influenced by the enactment of the procedure as well. Fairness concerns raised about the propriety of a decision maker's behavior during the enactment of procedures are representative of a desire forinteractional justice. In this paper, we present three studies that examine the effects of giving acausal account, or a justification, versus not providing a justification, on judgments of interactional fairness and endorsement of a decision maker's actions. In Study I, a laboratory study, ratings of interactional fairness and support for a manager were higher when subjects received a causal account that claimed mitigating circumstances for a manager's improper action than when they did not receive such a causal account. A second laboratory study replicated the same pattern of findings in two different organizational contexts. In addition, it was found that the perceived adequacy of the causal account was a critical factor explaining its effect. In Study 3, a field setting, ratings of both interactional fairness and procedural fairness were higher when a manager provided anadequate causal account to justify the allocation of an unfavorable outcome. The discussion focuses on the implications of these findings for research on interactional and procedural justice.  相似文献

We analyze a seemingly simple question: When should government share private information that may be useful to terrorists? Policy makers' answer to this question has typically been “it is dangerous to share information that can potentially help terrorists.” Unfortunately, this incomplete response has motivated a detrimental increase in the amount of information government keeps private or labels “sensitive but unclassified.” We identify two distinct types of private information that are potentially useful to terrorists and identify the range of conditions under which sharing each can enhance counterterrorism efforts. Our results highlight the complex trade-offs policy makers face in deciding how much openness is right in a world where protecting the people from terrorists has become a central duty of government.  相似文献
