提高本科生导师制的有效性

本科生导师制是我国本科教学改革的重要内容,它的实施深受学生的欢迎,但其实施结果的有效性不高.本科生导师制有效性不高的主要原因有:导师职责定位大而全;师生之间的互动不够频繁;师生的权利义务不对等;相应的配套措施不够完善.要提高本科生导师制的有效性,应该恰当定位本科生导师的职责,保证充足的导师资源,完善相应的制度,采取多种方式增强师生的互动.     

公司治理质量与盈余质量——基于中国治理指数(CCGINK)的初步证据

本文依据南开大学公司治理研究中心公开的中国治理指数数据选择高治理质量公司,并根据自行计算的治理指数选择低治理质量公司,研究了公司治理高低对盈余质量的影响.基于收益-盈余模型,使用2002年和2004年的数据,本文发现(1)公司治理质量显著影响到了盈余质量,高治理质量公司的盈余反应系数显著高于低治理质量公司;(2)高治理质量公司的盈余变化较之低治理质量公司的盈余变化具有更为显著的价值相关性.     

Referent Networks Predict Just Rewards

This study introduces the referent network, the set of relations defined by knowing others reward levels, and makes initial predictions about how the structure of that network shapes perceptions of income fairness. Previous research recognizes that justice assessments are driven by social comparisons; yet there is a paucity of research on how the structure of interpersonal contacts shapes justice assessments. Using a social networks perspective, the arguments here suggest that the referent network affects social comparisons, which in turn affect justice assessments of rewards. This reasoning is also integrated with the notion that people make both local and referential comparisons when determining their just rewards. An experiment evaluates these arguments. Results show support for the argument linking network structures to justice assessments and partial support for the extension to local and referential comparisons. Supplemental analyses show how reward levels qualify the arguments. Implications and directions for future research are discussed.     

The Effects of Three Types of Sexual Orientation Victimization on HIV Sexual Risk Behavior Among Black South African Men Who Have Sex With Men (MSM)

ABSTRACT

The goal of this study is to examine the relations between histories of three types of sexual orientation victimization (childhood, personal, and institutional) and HIV sexual risk behavior among Black South African men who have sex with men (MSM). Secondarily, this study examines whether marijuana use and problem drinking mediate the relations. Participants were 125 Black MSM recruited from neighborhoods in Eastern Cape Province, South Africa. Questionnaires administered through audio computerized self-interviewing assessed sexual orientation victimizations, problem drinking and marijuana use, and unprotected anal sex with casual partners. Data were analyzed using multiple regression and multiple mediation modeling.

Personal and institutional sexual victimizations were associated with condomless anal sex. Childhood sexual orientation victimization was positively associated with problem drinking. Neither problem drinking nor marijuana use mediated the relations between sexual orientation victimizations and having condomless anal sex with casual partners.

Effect of Pet Dogs on Children's Perceived Stress and Cortisol Stress Response

The present study tested whether pet dogs have stress‐buffering effects for children during a validated laboratory‐based protocol, the Trier Social Stress Test for Children (TSST‐C). Participants were 101 children aged 7–12 years with their primary caregivers and pet dogs. Children were randomly assigned in the TSST‐C to a pet present condition or one of two comparison conditions: parent present or no support figure present. Baseline, response, and recovery indices of perceived stress and cortisol levels were computed based on children's self‐reported feelings of stress and salivary cortisol. Results indicated that in the alone (no social support) condition, children showed the expected rise for both perceived stress and cortisol response to stress. Pet dog presence significantly buffered the perceived stress response in comparison to children in the alone and parent present conditions. No main condition effect was observed for cortisol; however, for children experiencing the stressor with their pet present, lower cortisol response to stress was associated with more child‐initiated petting and less dog proximity‐seeking behavior. The results support the notion that pet dogs can provide socio‐emotional benefits for children via stress buffering.

活化中国传统文化资源 提升大学生的思想道德素质

在我国改革开放的过程中,由于外来文化的涌入,价值选择趋向多元化,使当今的大学生在道德选择中出现了迷茫,对现行的一些硬性道德教育从内容到形式不感兴趣且有逆反心理。而历史已经证明,应对外来文化的冲击,最有力的武器只能是优秀的民族传统文化。活化中国优秀的传统文化,加强其在高校的教育力度,可以培养大学生的民族灵魂和中国精神,提升大学生基本的思想道德品质。文章从大学生思想道德调查的现状入手,论述了应在哪些方面对大学生进行中国优秀传统文化熏陶,最后提出了对大学生进行中国优秀传统文化熏陶的几种具体方法。     

“五四”运动以来民间语言研究的传统与新时期语言民俗学的开拓

现代意义的中国民俗学自“五四”时期兴起以来 ,在开始阶段曾对口头语言问题非常重视 ,并开展了不少相关的活动与研究 ,在当时有着特殊的作用与重大的影响。但后来很长的一段时期 ,民俗学领域的语言研究开展得很少。黄涛所著《语言民俗与中国文化》是民俗学领域内对语言民俗进行专业研究的开拓之作 ,在语言民俗学的基本理论和研究方法上做了有益而且较为成功的尝试。
