当代大学生创业意向影响因素研究

为了深入了解当代大学生的创业意向及其影响因素,研究者以全国30所高校5000多名大学生为被试,对影响大学生创业意向的诸多因素进行了分析。研究发现:当代大学生的创业意向在性别、奖学金获得次数、学生干部经历、出生地上均存在一定差异。大学生主客观条件中的性别、学校性质、创业兴趣、创意能力改善对创业意向有显著影响。创业教育和创业环境认知的引入对于预测大学生的创业意向均有增量效度,能够在个体的主客观条件以外解释个体创业意向的变异。在大学生认知中,影响创业成功的因素主要由客观背景资源、主观能力经验和外部宏观环境3个因子组成,其中主观能力经验的作用排在首位。     

山东出土商代青铜器铭文字频状况探析

对2008年12月底前公布的山东出土商代青铜器铭文资料进行统计,可得单字645个,不计重复字为154个。进行字频统计与测查,发现：字频分布呈现两极分化,最高字频覆盖率达9%,即每11字就出现1次;仅出现1次的有109字,约占单字总数的71%。高频字集中在亲称用字、日名用字、作器或器名用字以及部分族名。亲称高频字是＂父＂。日名高频字集中在双数日,未见＂丙＂、＂壬＂。这些情况反映出商代山东与中原铜器铭文的一致性与差异性。     

中学生消费决策风格的特点及其与家庭理财教育方式的关系

该研究以377名中学生为被试,探讨了中学生消费决策风格的特点及其与家庭理财教育方式的关系。结果表明:(1)中学生消费决策风格部分符合Shim(1996)提出的二阶模型(包括质量导向、非理性导向、享乐导向和价格导向等四个二阶因子);(2)中学生消费决策风格的年级差异不显著,性别差异显著,男生在品牌导向上高于女生,在流行导向和娱乐导向上低于女生;(3)中学生消费决策风格可划分为决策随意型、决策紊乱型、决策理智型和决策实惠型;(4)父母消极的理财教育方式会导致中学生形成非理性导向或享乐导向的消费决策风格,而积极的教育引导则能在一定程度上减弱中学生的非理性决策风格,促进其形成质量导向的决策风格。     

基于文化的心理复原力研究

随着对个体心理复原力研究不断深入,文化作为影响个体心理复原力的重要因素日益受到关注,研究者在厘清文化与复原力之间的关系后,尝试以积极心理学的视角,将中国传统文化中"天人合一"、"以人为本"、"自强不息"、"厚德载物"等文化精神引入到个体心理复原力发展的过程中,为个体心理复原力的研究贡献价值。     

玛雅历法和2012年预言

本文详细介绍分析了玛雅"长数"历法中对2012年的"预言"以及相关的几种玛雅历法。玛雅各种历法的产生和运用都和玛雅创世神话及宗教信仰直接相关。文中列举了玛雅纪念碑和手抄本中的历史记载。从玛雅历法的循环性质可以得出结论:2012年12月23日并非玛雅人预告的"世界末日",而仅仅是一个记日历法中一个循环期的结束和另一个循环期的开始。     

Stress induces glucocorticoid-mediated apoptosis of rat Leydig cells in vivo

Stress can disrupt endocrine signalling in the male reproductive axis through high concentrations of glucocorticoids, the hallmark of stress. Our previous work revealed that a stress level of exogenous glucocorticoids could induce apoptosis of rat Leydig cells, which are the primary source of testosterone. The aim of this study was to investigate whether stress can induce apoptosis in rat Leydig cells in vivo and, if so, whether the process is the result of a direct effect of glucocorticoids. In a chronically stressed rat model, serum corticosterone concentration was increased significantly whereas serum testosterone was decreased. The frequency of apoptotic Leydig cells in stressed rats was also increased. Adrenalectomised rats subjected to chronic stress showed an elevated serum testosterone, while the apoptotic frequency of Leydig cells was not increased. It was established that glucocorticoid-induced Leydig cell apoptosis is mediated by glucocorticoid receptors (GRs), which translocate from cytoplasm to nucleus. Adenovirus microRNA-induced downregulation of GR expression in vitro alleviated the corticosterone-induced increase in apoptosis of Leydig cells. These results indicate that the stress-induced increase in corticosterone secretion resulted in apoptosis in rat Leydig cells in vivo, and thereby decreased testosterone synthesis.     

Predictors of Deliberate Self-Harm Behavior Among Emerging Adolescents: An Initial Test of a Self-Punitiveness Model

The current study examined the extent to which an expanded self-punitiveness model could be applied to deliberate self-harm (DSH) among students making the transition to university. Specific components of the self-punitiveness model included perfectionism, overgeneralization, self-criticism, and shame. A sample of 319 university students completed a measure of deliberate self-harm as well as two multidimensional perfectionism measures and measures of self-criticism, overgeneralization, and shame. Correlational analyses found few significant associations among deliberate self-harm and the self-punitiveness factors among men. In contrast, among women, deliberate self-harm was associated with dimensions of trait perfectionism such as parental criticism and socially prescribed perfectionism, as well as with overgeneralization, self-criticism, and both characterological shame and bodily shame with the strongest associations found with shame. Supplementary analyses found a strong link between overgeneralization and shame and an association between self-criticism and shame among women. The results support the contention that particularly among young women making the transition to university, deliberate self-harm behavior is a reflection of a self-punitive personality orientation with multiple facets and a sense of shame associated with an overgeneralized sense of failing to meet social expectations.     

Racial and Ethnic Differences in Direct-to-Consumer Genetic Tests Awareness in HINTS 2007: Sociodemographic and Numeracy Correlates

To examine the association of 1) race/ethnicity and 2) numeracy with awareness of DTC genetic tests. Secondary analysis of 6,754 Hispanic, black, and white adult respondents to the National Cancer Institute’s 2007 Health Information National Trends Survey (HINTS). Logistic regression was used to examine sociodemographic predictors of DTC genetic tests awareness including race/ethnicity, income, education, and gender. Next, two numeracy variables were added to the model. After controlling for sociodemographic variables, black respondents were significantly less likely to have heard of DTC genetic tests compared to white respondents (OR = 0.79; CI: 0.65–0.97). When numeracy variables were added to the model, the effect of black race was no longer significant (OR = 0.84; CI: 0.69–1.04). Hispanic respondents did not significantly differ from white respondents in awareness of DTC genetic tests. Other significant correlates of DTC genetic tests awareness in the full model included education, income, age, and numeracy variables including degree to which people use medical statistics and numbers to make health decisions, and preference for words or numbers when discussing “the chance of something happening.” Although black respondents were generally less aware of DTC genetic tests than white respondents, this relationship appears to be partially mediated by numeracy.     

Direct-to-Consumer Personal Genomic Testing: A Case Study and Practical Recommendations for “Genomic Counseling”

Technological advances and information-seeking consumers have pushed forward the movement of direct-to-consumer (DTC) genetic testing. Just like with other types of testing, there are potential risks, benefits and limitations. A major limitation of DTC testing is the incomplete view it provides regarding lifetime risk for common, complex diseases, since most tests only analyze 1–2 single nucleotide polymorphisms (SNPs) and do not include evaluation of medical or family histories, which is necessary to risk assessment. Further, it is not currently well-established whether personal genomic testing results will lead toward improved health behaviors, adverse psychological effects or potential overuse of the health care system. To display these and other issues, we present an in-depth case study of an individual who ordered DTC genetic testing and subsequently sought genetic counseling. This case presents a unique learning experience for the field of genomic counseling, as the patient did not fit the typical assumptions regarding ‘early adopters’ of DTC testing. It also allowed the genetics health care providers involved in the case to identify gaps in current genetic counseling practice that need to be filled and approaches to employ for successful delivery of genomic counseling. Based on our experience, we developed practical recommendations for genomic counseling, which include novel approaches to case preparation, use of electronic tools during the counseling session, and focusing on education as the major component of the genomic counseling session, in order to provide patients with the knowledge necessary to independently interpret and understand large amounts of genomic testing information provided to them.     

A Mediated Moderation Model of Conformative Peer Bullying

We investigated the relationship between conformative peer bullying and issues of peer conformity among adolescents. This relationship is examined through the establishment of a mediated moderation model for conformative peer bullying using structural equation modeling in a sample of 391 second-year middle school students in Seoul, South Korea. We found that peer pressure and resistance to peer influence interact with one another to affect antisocial conformity, which then affects conformative peer bullying, thereby establishing its mediated moderation effect. The results suggest that conformative peer bullying that encourages and assists active bullies is affected by antisocial conformity; moreover, an individual’s capacity to resist peer influence plays a protective role against peer conformity, and this must be acknowledged as a significant influence in conformative peer bullying among adolescents.
