暴力犯罪的媒体诱因与对策反思——规避模仿示范效应的新路径

媒体对暴力犯罪的不当报道，会对潜在犯罪者起到模仿示范效应。鉴于新闻传媒客观、如实反映事件的职业伦理，其应当于公众知情权与犯罪预防间寻求平衡。但此种平衡未必尽然体现为“冷处理”式的抑制，必要时，在恪守媒体报道“绝对禁区”的前提下，适度地对特定暴力犯罪予以“热处理”，不仅是无害的，而且，其本身即为规避模仿示范效应的另一种至关重要的途径。     

Age-Period-Cohort analysis: A design-based approach

This paper develops a design-based approach to identifying cohort effects in APC analyses. Cohort effects arise when one cohort is treated by a unique set of formative socialization experiences, which causes it to differ from other cohorts in relevant outcomes. APC analyses typically compare treated and untreated cohorts from a single population. Our approach introduces a second group—a control group, in which no unit is treated but that is otherwise similar to the first—and adapts difference-in-differences estimation to the APC framework. The approach yields two identification strategies, each based on transparent and testable assumptions. We illustrate how the method works and what is to be gained through three examples.     

Editor's note

This study applies Elisabeth Noelle‐Neumann's spiral of silence theory to the controversial issue of whether children with AIDS should be allowed to attend public school. The study tests the theory's hypotheses in light of two content analyses of the media's treatment of the issue. The findings offer tentative and qualified support for Noelle‐Neumann's theoretical propositions about the relationship between individuals' perceptions of the issue and the media's tenor of the issue; particularly that of television. The findings suggest the need to address the role of other agents of influence, including reference groups, and to use time‐based data to unravel the causal order of the relationships.     

论“附保护第三人作用的契约”

自德国产生“附保护第三人作用的契约”以来,其在德国的判例与学说中不断发展、繁荣。我国现也有不少学者在对其加以研究。其中最困难之处在于如何解释“附保护第三人作用的契约”与“债权相对性”之矛盾。笔者从契约效力根源的角度提出“系统契约论”,解释了“附保护第三人作用的契约”之理论根基,认为我国应引进此制度,并将其继续应用到“附保护第三人作用的契约”的构成要件、法律效果、与侵权法之边界等问题,也附带地以“系统契约论”解释了契约法上之其他问题。     

To Give or Not to Give: Modeling Individuals' Contribution Decisions

Employing data from a recent national survey on campaign finance, we examine the contribution behavior of individual citizens in the 2000 election. By disaggregating types of contributions, our model enables us to observe potential heterogeneity in the determinants of giving money to parties and candidates. We find that for both types of contributions, the effects of informational resources and solicitation on the decision to contribute outweigh those of financial resources. In addition, we propose both a theoretical and an empirical distinction between the selection effects of solicitation and the stimulus effects of solicitation. By distinguishing between these dual dimensions of solicitation, our analysis provides new insight into the causal linkages between income, solicitation, and contributions. We find that while solicitation increases the likelihood of contributing through selective targeting or rational prospecting, it also does so through a stimulus mechanism.     

Mediators of the Relation Between Beliefs in a Just World and Emotional Responses to Negative Outcomes

Research shows that strong believers in a just world respond with less negative and more positive emotion to their own negative outcomes than do weak believers. The present study investigated mediators of this relation. We proposed that strong believers in a just world (versus weak believers) would make stronger internal and weaker external attributions for their negative outcomes, leading to reduced perceived unfairness, which, in turn, was expected to lead to less negative and more positive emotion. We assessed the just world beliefs of a sample of undergraduates as well as measuring their cognitive and emotional responses to an exam grade. Mediational analyses showed that our data were consistent with the processes proposed above. Various cognitive and motivational interpretations of the present findings are discussed     

Assessing Stability and Change in Criminal Offending: A Comparison of Random Effects, Semiparametric, and Fixed Effects Modeling Strategies

An important theoretical problem for criminologists is an explanation forthe robust positive correlation between prior and future criminaloffending. Nagin and Paternoster (1991) have suggested that the correlationcould be due to time-stable population differences in the underlyingproneness to commit crimes (population heterogeneity) and/or thecriminogenic effect that crime has on social bonds, conventionalattachments, and the like (state dependence). Because of data andmeasurement limitations, the disentangling of population heterogeneityand state dependence requires that researchers control for unmeasuredpersistent heterogeneity. Frequently, random effects probit models havebeen employed, which, while user-friendly, make a strong parametricassumption that the unobserved heterogeneity in the population follows anormal distribution. Although semiparametric alternatives to the randomeffects probit model have recently appeared in the literature to avoid thisproblem, in this paper we return to reconsider the fully parametric model. Viasimulation evidence, we first show that the random effects probit modelproduces biased estimates as the departure of heterogeneity from normalitybecomes more substantial. Using the 1958 Philadelphia cohort data, we thencompare the results from a random effects probit model with a semiparametricprobit model and a fixed effects logit model that makes no assumptions aboutthe distribution of unobserved heterogeneity. We found that with this dataset all three models converged on the same substantive result—evenafter controlling for unobserved persistent heterogeneity, with models thattreat the unobserved heterogeneity very differently, prior conduct had apronounced effect on subsequent offending. These results are inconsistentwith a model that attributes all of the positive correlation between priorand future offending to differences in criminal propensity. Sinceresearchers will often be completely blind with respect to the tenabilityof the normality assumption, we conclude that different estimationstrategies should be brought to bear on the data.

试论《劳动合同法》的实施效果与运行障碍

<劳动合同法>的颁布和实施引起强烈的社会反响,人们寄望于这部法律扭转当前的劳资格局,建立和谐稳定的劳动关系.但是,这部法律的良好实施取决于用人单位守法的自觉度、劳动者权利意识的觉醒度和劳动保障监察的力度.只有改革现行的社会保险制度,细化<劳动合同法>的抽象条款,加大<劳动合同法>的宣传力度和监察力度,才能取得良好的实施效果.
