我国地方保护主义的效应探析

地方保护主义在不同的阶段表现出不同的特点,保护手段也由"硬"转"软",由"明"转"暗"。对于地方保护主义的效应分析,从短时期和局部来看有一定益处,但从长期和全局来看,它造成了效率的降低,分配的不公平,乃至整个国家经济的衰败和没落。打破地方保护主义,建立一个统一大市场,统一竞争秩序和规则,是当前一项紧迫的任务。     

用“咖啡环”法估测DNA含量

目的探讨DNA-溴化乙锭形成的"咖啡环"用于DNA含量的测定。方法将DNA与溴化乙锭混合,滴加在载玻片等载体上,蒸发后用凝胶成像系统观察、拍照,分析DNA的成环条件、环荧光强度与DNA浓度的相关性,以及"咖啡环"法评价DNA的灵敏度、适用范围等。结果 DNA-溴化乙锭溶液在载玻片、透明聚苯乙烯板等载体表面蒸发后可形成荧光环。在玻片上2μL点样时,DNA检出限可达到2ng/μL。在2ng/μL~1000ng/μL范围内,DNA浓度与环积分光密度拟合Logistic方程(R2=0.999)。结论 "咖啡环"法简单、快速,设备要求低,可用于DNA含量的高效、快速测定。

Responses to Gender Inequality in the Division of Family Work: The Status Quo Effect

This study addresses responses to gender inequality in the division of family work as well as the outcomes of those responses. Ninety-eight husbands and 95 wives responded to stimulus information manipulated by means of scenarios. Participants reported more wife-demand/husband-withdraw interaction than husband-demand/wife-withdraw interaction when the wife was discontent with her spouse's contribution to family work, but the demand/withdraw interaction patterns were reported equally when the husband was discontent. The data showed support for the Status Quo Effect Hypothesis: The likelihood that the spouse's contribution to family work remained unchanged (i.e., status quo maintenance) was rated higher than the likelihood that the spouse would increase his/her contribution to family work. In line with this, when the wife was discontent, wife-demand/husband-withdraw interaction was negatively related to the likelihood that the spouse would do more family work. Finally, participants reported a greater likelihood for discontent spouses than for content spouses to increase their own contribution, but discontent husbands were more likely to do so than discontent wives.     

现阶段我国公安“打击与防范”关系浅析

"打击与防范"是公安机关的重要工作和两大职能。公安的"打击与防范"具有一致性,辩证统一性,二者是成本与效益、治标与治本的关系。正确处理二者的关系是做好公安工作,有效地维护社会治安的关键。     

Juror Sensitivity to the Cross-Race Effect

Black and White mock jurors' sensitivity to the cross-race effect was investigated by varying the race of the eyewitness in a simulated murder trial of a Black defendant. Participants heard an audiotape of a trial after which they rendered a verdict and rated the credibility of the witnesses. White participants found the prosecution witnesses (including the eyewitness) more credible, and the defense witness less credible, than did Black participants; they were also more likely to find the defendant guilty. The Black eyewitness was perceived as more credible than was the White eyewitness, but eyewitness race had no effect on verdict. These results are consistent with the literature indicating that jurors of different races reach different verdicts, and also that jurors are relatively insensitive to factors that affect eyewitness testimony, such as the cross-race effect.     

Comparing Effect Sizes in Follow-Up Studies: ROC Area,Cohen's <Emphasis Type="Italic">d</Emphasis>, and <Emphasis Type="Italic">r</Emphasis>

In order to facilitate comparisons across follow-up studies that have used different measures of effect size, we provide a table of effect size equivalencies for the three most common measures: ROC area (AUC), Cohen's d, and r. We outline why AUC is the preferred measure of predictive or diagnostic accuracy in forensic psychology or psychiatry, and we urge researchers and practitioners to use numbers rather than verbal labels to characterize effect sizes. Strictly speaking, d values pertain only to variables scored on an interval scale. When the nondichotomous variable is ordinally scaled, r or AUC should be used. Nevertheless, the values in Table 1 allow one to compare the relative magnitudes across studies that have reported any of the three effect size measures.

真伪储蓄合同之辨——储蓄合同效力的考察

本文从主体适格、意思表示真实和不违反法律和公共利益三个角度分析了储蓄合同的效力 ,提出了两个主要观点 :一是不能一概排除无民事行为能力人订立储蓄合同的资格 ,无民事行为能力人订立的储蓄合同应作为效力待定合同通过法定代理人的允许或承认而发生法律效力 ;二是反对高息纳储不等于取消利率的任何差别 ,只有在国家严格监管下允许储蓄机构利用一定的利率浮动进行合理竞争 ,才能既维护金融秩序的稳定又保障储蓄业务的健康活力。
