Steps toward an evolutionary personality psychology: Individual differences in the social rank domain.

A comprehensive evolutionary personality psychology can be developed by identifying individual differences within each of the evolved systems that regulate social behaviour. We developed a questionnaire measure of social rank style, defined as individual differences in preferred strategies for pursuing, defending, and, when necessary, relinquishing social rank. The 17-item Rank Style with Peers Questionnaire (RSPQ) comprises three nearly independent scales: dominant leadership, coalition-building, and ruthless self-advancement. A series of studies demonstrated that: (a) the RSPQ’s, factor structure is robust; (b) the three rank style variables are not redundant with the five-factor traits or adult attachment styles; (c) they are related in theoretically expected ways to adjustment outcomes, to agentic and communal interpersonal behaviours, and to social reputations; (d) they predict group and individual performance outcomes relevant to organisational psychology; and (e) they are related in theoretically expected ways to psychopathology, including social anxiety disorder and depressive symptoms. Future directions for research on social rank styles and prospects for an evolutionary personality psychology are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Predicting student attitudes about racial diversity and gender equity.

[Correction Notice: An erratum for this article was reported in Vol 4(3) of Journal of Diversity in Higher Education (see record 2011-16523-001). There are two errors in Table 2 under the RWA heading and the Cog-gender heading. The necessary changes are provided in the erratum.] [Correction Notice: An erratum for this article was reported in Journal of Diversity in Higher Education on August 1 2011 (see record 2011-16523-001). There are two errors in Table 2. Under the RWA heading, the SDO row should have indicated a positive correlation of .266**, not -.266**. Under the Cog-gender heading, the SDO row should have indicated a negative correlation of -.438**, not .438**.] Factors related to attitudes about racial diversity and gender equity were examined in an ethnically diverse sample of 432 college students (167 European Americans, 83 African Americans, 81 Asian Americans, and 82 Hispanic Americans). In addition to variables of self-interest (i.e., ethnicity, gender, and political views), social ideology (i.e., social dominance orientation, right-wing authoritarianism) and personality traits (openness to experience) were uniquely predictive of attitudes about racial diversity and gender equity. Hierarchical regressions revealed that social dominance orientation most strongly predicted racial attitudes, while right-wing authoritarianism most strongly predicted gender attitudes. Implications for diversity education efforts related to prejudice reduction are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)

Interpersonal problems, personality pathology, and social adjustment after cognitive therapy for depression.

The authors examined the level and structure- of the Inventory of Interpersonal Problems--Circumplex version (IIP-C; L. M. Horowitz. L. E. Alden, J. S. Wiggins, & A. L. Pincus, 2000) before and after 20 sessions of acute-phase cognitive therapy for depression (N=118), as well as associations with the Schedule for Nonadaptive and Adaptive Personality (L. A. Clark, 1993b) and the Social Adjustment Scale--Self-Report version (M. M. Weissman & S. Bothwell, 1976). Interpersonal problems had a 3-factor structure (Interpersonal Distress, Love, and Dominance), with the latter 2 factors approximating a circumplex, both before and after therapy. Interpersonal Distress decreased and social adjustment increased with therapy, but the Love and Dominance dimensions were relatively stable, similar to personality constructs. Social adjustment related negatively to Interpersonal Distress but not to Love or Dominance. Personality pathology related broadly to Interpersonal Distress and discriminantly to Love and Dominance. These findings support the reliability and validity of the IIP-C and are discussed in the context of personality theory and measurement.

对角切片谱法分析信号中相位耦合的频率分量

给出了三阶累积量对角切片谱的性质，分析了水中目标辐射信号的特点，并将3阶累积量对角切片谱法应用于提取水下目标辐射信号中相位耦合的频率分量。以水下某目标辐射噪声的实测数据为例，进行了仿真研究。结果表明，该方法在提取水下运动目标辐射信号中的参加相位耦合的频率分量和相位耦合产生的频率分量、抑制环境噪声和非耦合的频率分量等方面的性能优于自相关谱法。     

高层框架-核心筒及衍生结构体系主要抗侧组件分析

为更加深入和系统地了解高层建筑中应用最广的框架-核心筒结构,基于构件的受力特点,首次提出了抗侧组件的概念,指出核心筒、腹板框架和翼缘框架为该种结构体系的三个主要抗侧组件。基于6栋普通框架-核心筒结构及衍生结构体系的高层塔楼,计算了主要抗侧组件所承担的倾覆力矩比例来衡量其抗侧能力,详尽剖析了抗侧组件的工作原理。通过量化各抗侧组件的抗侧效能,使框架-核心筒结构的抗侧体系设计更加明晰。结果表明:在普通框架-核心筒、筒中筒、带环桁架的框架-核心筒结构中,核心筒为关键抗侧组件;单独带巨撑或伸臂的框架-核心筒结构中,关键抗侧组件分别是腹板框架和翼缘框架。     

WGC特征描述的人脸表情识别

针对韦伯局部特征(WLD)仅计算中心像素与周围像素差异提取特征的不足,提出了一种韦伯梯度编码(WGC)特征描述的人脸表情识别算法。首先计算当前像素点周围水平、垂直和对角位置上的数值差与当前像素点的差异构成WGC特征的差动激励;然后进一步提出基于水平和对角线优先原则的WGC_HD特征;最后利用最佳分块方式得到行分块WGC_HD特征,采用自动优化参数的SVM分类器完成人脸表情识别。在公共人脸表情库JAFFE和CK库上进行交叉实验,平均识别率及平均特征提取时间分别为95.49%、12.30 ms和97.63%、31.54 ms。行分块WGC_HD特征考虑了不同梯度方向的像素差异,较好描述了表情图像的局部结构信息且具有较低的时间复杂度,与目前典型的表情识别算法结果对比也验证了算法具有较高的识别精度。
