A correction and a comment on Craig and Lyle (2001)

In a recent paper, Craig and Lyle (2001) measured tactile spatial acuity on the palm and compared these results with the results from similar measures on the fingertip. The changes in sensitivity between the two sites appeared to be consistent with estimates of the relative density of innervation between the two sites. Rather than compare their results with changes in the density of innervation, Craig and Lyle should have compared them with changes in the spacing between receptors. On this basis, psychophysical performance is much poorer on the palm than one would predict on the basis of the spacing between receptors. Some possible reasons are offered for the difference between the psychophysical results and the predictions based on receptor spacing.     

Exploring the Relationship between Market Orientation and Sales and Marketing Collaboration

The relationship between sales and marketing has generated considerable academic interest in recent years, with studies focusing on how the interface can be improved. However, prior research has neglected an important aspect of this interface: the relationship between market orientation and collaboration between sales and marketing. This study considers this relationship and was carried out through a survey of managing directors/chief executives. The results indicate that collaboration between sales and marketing has a positive relationship with market orientation and that collaboration between sales and marketing as well as market orientation have a combined positive effect on business performance.     

Age and Education Differences in Marriages and their Effects on Life Satisfaction

Within marriages husbands typically tend to be older and higher educated than their wife. This paper tries to explain this by analyzing whether age and education differences between spouses have an effect on happiness. Two alternative hypotheses are tested on the relation between age and education gaps between partners and life satisfaction. It is found that a positive age gap between husband and wife increases both male and female life satisfaction, while female life satisfaction increases if the education gap is smaller.     

相对剥夺感与社会适应方式：中介效应和调节效应

以6175名17岁以上的个体为被试, 采用四种自编问卷考察了相对剥夺感对创新和反叛这两种社会适应方式的影响, 归因方式在其中的中介作用和调节作用, 同时还考察了反叛在相对剥夺感和创新关系中的调节作用。结果发现：①相对剥夺感对创新和反叛具有正向预测作用, 相对剥夺感越高, 创新和反叛的程度越强烈; ②归因方式对相对剥夺感和创新的关系起部分中介作用, 对相对剥夺感和反叛的关系起部分中介作用; ③归因方式在相对剥夺感和反叛的关系中起调节作用, 能增强相对剥夺感和反叛之间的关系; ④在下层阶层中, 反叛在相对剥夺感和创新的关系中起调节作用, 能减弱相对剥夺感和创新之间的关系。综上所述可以认为, 相对剥夺感对社会适应方式具有正向预测作用; 归因方式对相对剥夺感与社会适应方式的关系起部分中介作用; 在弱势群体阶层中, 反叛能减弱相对剥夺感对创新的直接影响。     

有中介的调节变量和有调节的中介变量

研究了有中介的调节效应模型和有调节的中介效应模型,两种模型都涉及到中介变量和调节变量。分别讨论了这两种模型的分析方法,两者基本上都是按中介效应模型的分析步骤,但其中都有一步要做调节效应的分析。还讨论了同时包含有中介的调节变量和有调节的中介变量的混合模型。最后,作为示范例子,用混合模型分析儿童行为对同伴关系的影响,结果发现,如果混合模型中的调节都设定是线性的,那么调节变量对因果关系是二次调节     

Work and Individual Determinants of Intrinsic Work Motivation, Emotional Exhaustion, and Turnover Intention: A Multi-Sample Analysis

This study tested the influence of personal characteristics on a pattern of specific relationships between work characteristics and psychological outcomes. The study hypotheses were: (1) Growth Need Strength has a direct effect on intrinsic work motivation and moderates the relationship between task characteristics and intrinsic work motivation; (2) Negative Affectivity has a direct effect on emotional exhaustion and moderates the relationships between workload and social support on the one hand and emotional exhaustion on the other; and (3) Upward Striving has a direct effect on turnover intention and moderates the relationship between unmet career expectations and turnover intention. These hypotheses were tested in two samples (bank employees and teachers) using Multi-Sample Analysis. The results showed that, generally, personal characteristics had a direct effect on the outcomes as hypothesized. We only found one moderating effect: Upward Striving moderated the relationship between unmet career expectations and turnover intention.     

Meditators and non-meditators on sustained and executive attentional performance

In order to gain a deeper understanding of the mindfulness construct and the mental health benefits associated with mindfulness-based programmes, the relation between mindfulness and its proposed core component attention was studied. Buddhist and Western mindfulness meditators were compared with non-meditators on tasks of sustained (SART) and executive (the Stroop Task) attention. Relations between self-reported mindfulness (FFMQ) and sustained and executive attention were also analysed. No significant differences were found between meditators and non-meditators either in sustained or executive attention. High scores on the FFMQ total scale and on Describe were related to fewer SART errors. High scores on Describe were also related to low Stroop interference. Mindfulness meditators may have an increased awareness of internal processes and the ability to quickly attend to them but this type of refined attentional ability does not seem to be related to performance on attention tests requiring responses to external targets.     

Achievement and affiliation motivation in career-oriented and homemaking-oriented college women

The purpose of this research was to investigate the possibility of an interaction between need for achievement and need for affiliation in career-oriented and homemaking-oriented college women. In the first study, scores on the appropriate scales (Achievement and Affiliation) of the Adjective Check List were obtained for 250 female college students, who were also classified as career or homemaking oriented on the basis of their responses to a questionnaire concerning postcollege plans. No significant differences were found between the career- and homemaking-oriented groups on Achievement and Affiliation; but, as predicted, a significant interaction occurred between the two variables. A second study, involving 257 college women and employing the same procedures and analysis, replicated the results of the original study: no main effects, but a significant interaction between Achievement and Affiliation. Implications of the findings for female career development and the counseling of women are discussed.     

Social axioms in Iran and Canada: Intercultural contact, coping and adjustment

A comparison was made between Iranian participants living in Iran, Iranian immigrants to Canada, and Canadian-born participants on the Social Axioms Scale (SAS), including a sixth dimension, Harmony. The Iranian immigrants to Canada endorsed views that were intermediate between the other two groups. In the data from Iran, the relationships between social axioms on the one hand and measures of active coping and adjustment on the other were examined. Belief in Reward for Application predicted Active Coping; acknowledgment of Social Complexity predicted Life-Satisfaction; and endorsement of belief in Harmony predicted Mastery. Those whose beliefs on Harmony and Social Complexity were closer to their country mean were higher on Mastery and Self-Esteem, but those whose beliefs on Fate Control were closer to the country mean showed lower Life-Satisfaction.     

Openness as a Predictor of Political Orientation and Conventional and Unconventional Political Activism in Western and Eastern Europe

This study provides a comprehensive investigation of the relationship between Openness and political orientation and activism in Europe. Analyses were conducted on the 4 waves of the European Social Survey, including large representative samples in up to 26 European countries (total N > 175,000). In line with previous studies, a robust, positive relationship between Openness and left-wing political orientation was obtained in Western Europe. However, in Eastern Europe, the relationship between Openness and political orientation was weaker, and reversed in 3 out of 4 waves. Moreover, Openness yielded significant positive relationships with unconventional activism and to a lesser degree with conventional activism. The magnitude of the relationship between Openness and activism was dependent on political orientation and region. Stronger associations between Openness and activism were found for those having a left-wing orientation in Western Europe, whereas in Eastern Europe, Openness was somewhat stronger related to activism for those having a right-wing orientation. In the discussion we elaborate on the role of the geopolitical context in the relationship between Openness and political variables.     

Longitudinal relationships between depressive symptoms and health in normal older and middle-aged adults

Comorbidity between health and depression is salient in late life, when risk for physical illness rises. Other community studies have not distinguished between the effects of brief and long-standing depressive symptoms on excess morbidity and mortality. S. Cohen and M. S. Rodriguez's (1995) differential hypothesis of pathways between depression and health was used to examine the relationships between health and depression in a prospective probability sample of 1,479 community-resident middle-aged and older adults. Findings suggest that different durations of depressive symptoms have different relationships to health. Health had an impact on short-term increases in depressive symptoms but depressive symptoms had a weaker impact on health. The reciprocal impact was indistinguishable from the health influence on depression. In contrast, longer term depressive symptoms had a clear impact on health. The results imply that physical illness can affect depressive states; depressive traits but not states can affect illness.     

Alexithymia and hypersensitivity to touch and palpation

Alexithymia appears to be directly related to the process of somatization of psychological distress that has not found verbal expression. The lack of a meaningful dialogue between mother and child in early infancy may predispose the development of an alexithymic strategy in expressing psychic and psychosocial stress. This can occur in the form of unpleasant bodily sensations or pain. The human skin is, in addition to the oral and gastrointestinal organs, the earliest contact sphere between the young infant and the environment. In a group of 312 randomly chosen patients at an outpatient primary health care clinic a significant relationship was found between palpational hypersensitivity to touch on the one hand and somatization proneness and the degree of alexithymia on the other hand.     

Childhood memories of threatening experiences and submissiveness and its relationship to hallucination proneness and ideas of reference: The mediating role of dissociation

Recent studies have emphasized the importance of childhood memories of threatening experiences and submissiveness in a diversity of psychological disorders. The purpose of this work was to study their specific relationship with hallucination proneness and ideas of reference in healthy subjects. The ELES scale for measuring memory of adverse childhood experiences, the DES ‐II scale for measuring dissociation, the LSHS ‐R scale for measuring hallucination proneness, and the REF for ideas of reference were applied to a sample of 472 subjects. A positive association was found between childhood memories of adverse experiences and hallucination proneness and ideas of reference, on one hand, and dissociation on the other. A mediation analysis showed that dissociation was a mediator between the memory of adverse childhood experiences and hallucination proneness on one hand, and ideas of reference on the other. When the role of mediator of the types of dissociative experiences was studied, it was found that absorption and depersonalization mediated between adverse experiences and hallucination proneness. However, this mediating effect was not found between adverse experiences and ideas of reference. The relationship between these last two variables was direct. The results suggest that childhood memories of adverse experiences are a relevant factor in understanding hallucination proneness and ideas of reference. Similarly, dissociation is a specific mediator between adverse childhood experiences and hallucination proneness.     

Self-concept and anxiety of adolescent and adult fathers

This study examines the relationship between the age of unmarried fathers and their self-concept and anxiety level. A total of 24 unmarried fathers (12 adolescents and 12 adults) comprised the sample. No significant differences were found between adolescent and adult fathers on self-concept or anxiety level. Findings are discussed with regard to the current status of research on adolescent fathers.     

Common Genetic and Environmental Influences on Major Depressive Disorder and Conduct Disorder

The evidence for common genetic and environmental influences on conduct disorder (CD) and major depressive disorder (MDD) in adolescents was examined. A sample of 570 monozygotic twin pairs, 592 dizygotic twin pairs, and 426 non-twin siblings, aged 12-18 years, was recruited from the Colorado Twin Registry. For the past year data, there was a significant correlation between the genetic influences on MDD and CD and, for the lifetime data, there was a significant correlation between the genetic influences on MDD and CD, and a significant correlation between the nonshared environmental influences on MDD and CD. Our results suggest that some genetic factors will increase an individual's vulnerability to both MDD and CD in adolescence.

印度的婆罗门教、佛教与中国的儒家、道家

印度的婆罗门教和中国的儒家学说都有着维护社会秩序、延续既有文明、创造符号体系的建构功能 ;与此相对立 ,印度的佛家和中国的道家学说则以反向解构的姿态分别对婆罗门教和儒家学说在民族文化的建构过程中所导致的异化现象进行了深刻的批判。这种建构与解构的关系体现了追求文明与反抗异化、积极进取与消极无为、崇尚秩序与回归自然之间的辩证关系。作为这种逻辑关系的历史性发展 ,印度宗教文化从婆罗门教到佛教再到印度教的发展过程 ,与中国世俗文化中儒家和道家之间的彼此更迭 ,都形成着“否定之否定”式的阶段性变革。

BDNF基因与抑郁

抑郁的发生发展具有重要的遗传基础。随着细胞分子生物学实验方法以及分子遗传技术的进步, 与神经可塑性有关的BDNF基因作为抑郁遗传学研究的候选基因日益受到关注。概观而言, 已有相关研究主要探查了BDNF基因与抑郁的直接关联, BDNF基因与其他基因对抑郁的交互作用, 以及环境因素对BDNF基因与抑郁关系的调节作用。然而, 研究结论尚存在分歧甚至相互矛盾。其原因包括研究设计、环境测量指标、抑郁测量方法与研究对象种族背景等方面的差异。未来研究可通过采用多基因–环境设计, 考察被试种族、性别和年龄的调节作用, 以及探究潜在的作用机制等进一步推进和深化有关BDNF基因与抑郁关系的研究。
