《史记》对汉初人口状况的记载分析

《史记·高祖功臣侯者年表》序中的“汉兴……户口可得而数者十二三”这句话,是关于汉初人口状况的最早记载。对这句话的不同理解,影响到人们对汉初人口数量及其他相关历史问题的看法。学界对于这句话有着多种理解。本文认为司马迁此语,应当仅是针对汉初朝廷直接控制区内的户口而言,当时占去最富庶的东、南半壁江山的诸侯王国,是被排除在外的。     

A Friend in Creed: Does the Religious Composition of Geographic Areas Affect the Religious Composition of a Person's Close Friends?

Numerous theories of religion rest on the assumption that the religious composition of local populations influences the religious identities of a person's close friends, but there have been few empirical tests of this assumption. Using a combination of data on the religious identity of close friends (from the 1988 and 1998 General Social Survey) and information on the religious composition of counties (from the U.S. Religious Congregations and Membership Study) we find that despite tendencies toward religious homogeneity, the religious composition of the surrounding population has an effect on the proportion of a respondent’s same‐religion friends and on the proportion of friends belonging to specific other religious groups. Local population characteristics are unrelated to the proportion of respondents’ friends known in congregational settings. Results have implications for a broad range of sociological theories of religion as well as research examining the impact of same‐congregation and same‐religion friends (e.g., health and well‐being).     

中介效应的检验方法和效果量测量:回顾与展望

通过中介效应检验方法之间的比较和效果量指标之间的比较,建议放弃将总效应c显著作为中介效应检验的前提条件,放弃基于直接效应c'显著性的完全和部分中介的提法,推荐使用偏差校正的百分位Bootstrap法直接对中介效应ab进行检验,使用κ²、R_med²等中介效果量指标并报告效果量的置信区间。作为示例,用R软件的MBESS软件包对某消防员饮食健康调查进行了中介效应检验和效果量测量。随后展望了中介效应检验方法和效果量测量的拓展方向。     

老年刻板印象威胁及其研究操纵

随着人口老龄化的不断加剧, 老年刻板印象威胁受到越来越多的关注。不同于种族或民族、性别等刻板印象威胁, 老年刻板印象威胁表现出累积性、共通性与连续性等特征。目前关于老年刻板印象威胁的研究多集中于认知老化尤其是记忆老化上, 关注老年刻板印象威胁对老年司机和老年员工的消极影响。消除与降低老年刻板印象威胁的消极效应可以从认知改变、群体认同、代际接触、老龄自我实现和个性化以及媒体宣传等五个方面来进行。在实验室研究中, 老年刻板印象威胁有外显与内隐两种不同的操纵形式。未来可以从扩展研究领域、细化“年龄”差异、比较整体效应大小和性别差异、侧重积极效应以及加强本土化检验和跨文化比较研究等方面来深化。     

Does performance on the standard antisaccade task meet the co-familiality criterion for an endophenotype?

The “co-familiality” criterion for an endophenotype has two requirements: (1) clinically unaffected relatives as a group should show both a shift in mean performance and an increase in variance compared with controls; (2) performance scores should be heritable. Performance on the antisaccade task is one of several candidate endophenotypes for schizophrenia. In this paper we examine whether the various measures of performance on the standard version of the antisaccade task meet the co-familiality criterion for an endophenotype. The three measures of performance—reflexive saccade errors, latency of correct antisaccades, and gain—show a wide range of effect sizes and variance ratios as well as evidence of significant or near significant heterogeneity. The estimated mean effect sizes [Cohen’s d: error rate: 0.34 (SD: 0.29); latency: 0.33 (SD: 0.30); gain: 0.54 (SD: 0.38)] are significantly greater than 0, but the magnitude of the departures from 0 is relatively small, corresponding to modest effect sizes. The width of the 95% confidence intervals for the estimated effect sizes (error rate: 0.2–0.49; latency: 0.17–0.50; gain: 0.23–0.85) and the coefficients of variation in effect sizes (error rate: 85.3%; latency: 90.9%; gain: 68.4%) reflect heterogeneity in effect sizes. The effect sizes for error rate showed statistically significant heterogeneity and those for latency (P = .07) and gain (P = .09) showed a trend toward heterogeneity. These results indicate that the effect sizes are not consistent with a single mean and that the average effect size may be a biased estimate of the magnitude of differences in performance between relatives of schizophrenics and controls. Relatives of schizophrenics show a small but significant increase in variance in error rate, but the confidence interval is broad, perhaps reflecting the heterogeneity in effect size. The variance ratios for latency and gain did not differ in relatives of schizophrenics and controls. Performance, as measured by error rate, is moderately heritable. The data do not provide compelling support for a consistent shift in mean or variance in relatives of schizophrenia patients compared with nonpsychiatric controls, both of which are required for a major gene involved in co-familial transmission. This set of findings suggests that although intra-familial resemblance in antisaccade performance is due in part to genetic factors, it may not be related to a schizophrenia genotype. Based on the current literature, it would be premature to conclude that any of the measures of antisaccade performance unambiguously meets the co-familiality criterion for an endophenotype.     

Effects of in-group and out-group support on behavioral consistency: The majority and minority in the context of an intergroup belief cross

Abstract:   The present study investigated the social determinants required to stimulate consistency in minority members' attitudes and behavior. The experiment was designed to examine the consistency of individuals in the context of an intergroup belief cross wherein the majority belief (or minority) in a categorical in-group shifted to the minority (or majority) in the out-group. The results indicated that the members of a majority within an in-group consistently preserved their behavioral intentions and beliefs even though they were positioned as a minority within an out-group. That is, the minority members in the whole intergroup context maintained consistency diachronically as a result of support from the majority of their in-group. The theoretical implications on the consistency of minority members, such as whistle-blowers in companies, are discussed.     

The Endorsement of Minority Rights: The Role of Group Position, National Context, and Ideological Beliefs

The present research was conducted in the Netherlands and used an experimental design to examine the endorsement of minority rights among Turkish and Kurdish participants in two framed, national contexts: the Netherlands and Turkey. In the Dutch context, each group is a minority, whereas in the Turkish context the Kurds are an oppressed national minority and the Turks are the national majority. The results showed that the Turks were less in favor of minority rights in the Turkish context than in the Dutch context, whereas the Kurds were more in favor of minority rights in the Turkish than in the Dutch context. In addition, the endorsement of minority rights was related to beliefs about majority rule, state unity, and ingroup identification, as well as to cultural diversity and perceived pervasive discrimination. The associations with the former three measures differed between the two groups and the two national contexts, whereas the latter two measures had main effects on the endorsement of minority rights.     

Translation and Standardization of the Sex-Role Egalitarianism Scale (SRES-B) on a German Sample

This study presents a German-language version of the sex-role egalitarianism scale (SRES-B) L. A. King, & D. W. King, 1993]. The SRES measures a person’s attitude toward egalitarianism between women and men. It has been normed on different populations, but there was no German version of the scale. The purpose of the present study was to translate and assess the psychometric properties of the SRES-B on a German population (n=379). As expected, sex, age, and educational level affected the scores of individuals on the scale. The results of factor analyses of the domain scores and correlations of subscales demonstrate a unidimensionality of the construct. The quality of the psychometric properties of items and scale was satisfactory. Implications and future directions for research are discussed.The research was conducted as part of the author’s master thesis, while at the University of Osnabrueck, Germany.
