关于证人证词可靠性的研究

证人的错误证词是导致错误判案的重要原因,因此如何鉴定证人证词的可靠性,从中去伪存真,对司法实践具有非常重大的意义。为此本文从情境、个体心理、社会心理三个方面分析影响成年证人证词可靠性的因素,并在此基础上探究应该采取何种措施来提高证词的可靠性与准确性。     

Demographic variables, smoking variables, and outcome across five studies.

OBJECTIVE: Intervention effectiveness can potentially be affected by membership in different demographic subgroups (race, ethnicity, gender, age, and education level) or smoking behavior variables (time to first cigarette, longest previous quit attempt, number of attempts in the past year, number of cigarettes, and stage of change). Previous research on these 2 sets of variables has produced mixed results. DESIGN: This secondary data analysis combined data from 5 effectiveness trials (a random-digit-dial sample [N=1,358], members of an HMO [N=207], parents of students recruited for a school-based study [N=347], patients from an insurance provider list [N=535], and employees [N=175]) in which smokers were all proactively recruited from a defined population and all received the same expert system intervention. The intervention produced a consistent 22% to 26% point prevalence cessation rate across the 5 studies. MAIN OUTCOME MEASURES: The main outcome measures were 24-hr point prevalence, 7-day point prevalence, 30-day prolonged abstinence, and 6-month prolonged abstinence. RESULTS: There were no significant differences in outcome across gender, race, and ethnicity subgroups. There were significant differences and small effect sizes for age and education subgroups. There were significant differences and large effect sizes for all 5 smoking behavior variables. DISCUSSION: Demographic variables are static variables, whereas the smoking variables are more dynamic, that is, open to change. Given the dynamic nature of the smoking variables and the large effect sizes, interventions tailored on the smoking variables should be more successful.     

慢性应激对大鼠行为和免疫细胞热休克蛋白70表达的影响

目的：研究慢性不确定应激对大鼠急性整体热水浴后外周血和脾脏免疫细胞热休克蛋白70（Heat shock protein 70, HSP70）表达的影响。方法：随机将大鼠分成慢性应激组和控制组（每组14只）。通过4周的慢性不确定性应激诱发实验组大鼠明显的抑郁行为,此期间控制组大鼠正常饲养。随后给予大鼠42度整体热水浴刺激,维持直肠温度41度25min。热刺激后6h,采用流式细胞仪测定大鼠外周血和脾脏免疫细胞HSP70 水平。结果：与控制组大鼠相比,慢性应激大鼠在急性热刺激后HSP70合成明显减少。控制组大鼠的所有被检测的免疫细胞热应激后HSP70合成均明显增加。相反,慢性应激大鼠仅在外周血的单核细胞和粒细胞检测到HSP70合成增加,同时升高的水平明显低于控制组大鼠。结论：慢性应激降低大鼠免疫细胞HSP70的热诱导反应,提示HSP70保护性作用减弱可能参与了慢性应激损害免疫细胞功能的生物学过程     

人到底从哪里来的？（三）

本文基于几种关于人之由来的说法出发，从科学角度回答“人不是神造的”这一问题。考察了近百年来人类化石发现过程，以及现代考古学、古人类学对人类起源与进化的科学分析，并以现代生物学对人体器官进化的研究成果，最终得出“人是进化的产物”的结论。     

Sender Demeanor: Individual Differences in Sender Believability Have a Powerful Impact on Deception Detection Judgments

Sender demeanor is an individual difference in the believability of message senders that is conceptually independent of actual honesty. Recent research suggests that sender demeanor may be the most influential source of variation in deception detection judgments. Sender demeanor was varied in five experiments (N = 30, 113, 182, 30, and 35) to create demeanor–veracity matched and demeanor–veracity mismatched conditions. The sender demeanor induction explained as much as 98% of the variance in detection accuracy. Three additional studies (N = 30, 113, and 104) investigated the behavioral profiles of more and less believable senders. The results document the strong impact of sender effects in deception detection and provide an explanation of the low‐accuracy ceiling in the previous findings.     

论加尔文对律法功用的阐述

加尔文在其《基督教要义》中从三个方面分析了律法在基督教信仰中的功用,即律法让人知罪的作用、维护人类社会秩序的作用、以及对信仰者之成圣生活的规范与引导作用。如果与路德关于律法的观念相对照的话,我们就会发现,路德更多地强调了律法的前两个方面的功用,即律法的消极方面的功用。他认为在基督教的成圣生活中似乎不需要强调律法。而加尔文则更多地强调了律法的第三个方面的功用,即对于信仰者成圣生活所起的引导和激发的作用。他认为圣灵正是借助着律法来引导信仰者,使其更加明白上帝的旨意。本文从律法的功用这一点入手,进一步分析了加尔文所理解的律法与恩典的关系,以及加尔文与路德律法观的区别。

Internet addiction,adolescent depression,and the mediating role of life events: Finding from a sample of Chinese adolescents

The aim of this study is to examine the mediating role of life events in the relation between Internet addiction and depression using an adolescent sample in China. A total of 3507 urban adolescent students were asked to complete the questionnaires including Young's Internet Addiction Scale, Adolescent Self‐Rating Life Events Checklist, and Center for Epidemiologic Studies Depression Scale, Parent–Child Conflict Tactics Scales, and demographic characteristics. Path analyses demonstrated that life events fully mediated the relationship between Internet addiction and adolescent depression. Specificity for the mediating role of life events was demonstrated in comparison to alternative competing mediation models. The findings support our hypothesis that the effect of Internet addiction on adolescent depression is mediated by the life events. Further research is required to test the temporal relationship between Internet addiction and adolescent depression and explore mechanisms underlying the pathways leading to adolescent depression.
