Emergent Leadership and Female Sex Role Identity

The effects of female sex role identity on self- and rater evaluations of emergent leadership behavior were compared in two studies. We used the same consensus-seeking procedure in both studies to collect the data; only the biological sex composition of the groups in the second study was changed. Study 1 examined 15 mixed-sex groups of 39 female and 21 male students; Study 2 contained 96 female students in 22 same-sex groups. Sex role orientation was measured with the Bern Sex Role Inventory (BSRI: Bem, 1974). Androgynous and feminine-oriented self-ratings of leadership were significantly higher than peer ratings and were also significantly higher than the undifferentiated self-ratings. The self-ratings of masculine-oriented women agreed most closely with peer ratings. Contrary to research and theory, peer evaluation of leadership behavior by sex role orientation did not differ.     

DETERMINATION AND EVALUATION OF RATE MEASUREMENTS IN THE ANALYSIS OF SPACE MEDICAL DATA

Measures of rate of change and of rate of rate of change are developed for application to physiological and psychological data. Examples are given of the use of these measures with heart-rate data for comparisons within and between subjects. It is shown that the measures provide information over and above that offered by means and variances, and that the measures appropriately reflect the impact of external variables.     

Campaign Contributions,Post-War Reconstruction Contracts,and State Crime

This article presents a case-control study of the relationship between Federal-level campaign contributions, corporate political connections, and the awarding of post-war reconstruction contracts in Iraq and Afghanistan. Cases are 135 companies that received post-war contracts and controls are 135 randomly selected companies matched on industry. Results reveal that both campaign contributions and political connections significantly increase a company's odds of receiving a contract. Results are situated in the context of current theory on state crime. It is argued that awarding contracts on this basis may constitute a form of state crime, but alternative explanations for the findings are also discussed.     

Why Do Parents Seek Help When Their Children’s Behavior Is Within Normative Levels?

The purpose of this study was to address the following question: Why do parents first seek help with parenting when they report their child’s disruptive behaviors are within normative levels? Two groups were selected for study from a sample of 91 parents of 3- to 6-year-olds who sought help with parenting: Parents reporting disruptive behavior problems in the normative range (n?=?22) or above a clinical cutoff (n?=?19). Logistic regression was used to examine two competing hypotheses about family variables which may account for why parents seek help when reporting normative levels of disruptive behaviors: Alternative family stress (i.e., high levels of family stress other than child disruptive behavior) and parent enhancement and validation (i.e., enhance and validate parenting although child behavior is in normal range). No support emerged for the alternative family stress hypothesis whereas multiple indicators (better use of disciplinary strategies, seeking services for a first born child, and being more highly educated) provided support for the parent enhancement and validation hypothesis.     

Curvilinear relationships between role stress and innovative performance: Moderating effects of perceived support for innovation

Curvilinear relationships between role stress and innovative performance were explored in a study conducted in Taiwan and mainland China. Results showed that when perceived support for innovation was low, role conflict showed a U‐shaped relationship with both self‐rated and supervisor‐rated innovative performance, which contrasts sharply with the well known inverted U‐shaped relationship between challenge stress and performance. Role ambiguity showed a similar but weaker pattern with regard to supervisor‐rated innovative performance. When perceived support for innovation was high, role conflict showed a generally positive relationship with both self‐rated and supervisor‐rated innovative performance, but role ambiguity showed no significant relationship with supervisor‐rated innovative performance. Theoretical and applied implications of these findings are discussed.     

When shared group membership signifies shared subjective experience: I-sharing and the minimal group paradigm

Ingroup favoritism is pervasive. It emerges even in the minimal group paradigm, where participants are assigned to novel groups based on seemingly insignificant characteristics. Yet many of the grouping schemes used in minimal group research may imply something significant: namely, that ingroup members will share in-the-moment subjective experience, or I-share. Two studies examine the role of inferred I-sharing in the minimal group paradigm. We found that (1) people inferred that they would I-share with ingroup members more than outgroup members; (2) inferred I-sharing increased ingroup favoritism; and (3) inferred I-sharing accounted for this ingroup favoritism. Moreover, expecting to I-share with the outgroup improved participants’ attitudes toward the outgroup. These results converge with other research suggesting that people favor ingroup members, in part, because they expect to I-share with them.     

囚徒困境决策中分离效应验证性与机制研究

Savage于1954年提出"确定事件原则"这一概念,Tversky和Slafir(1992)通过实验发现,人们在不确定条件下的决策过程中,会出现违背确定事件原则的现象,并把这种现象称为"分离效应"。尽管已经有很多对于二次赌博中分离效应的机制研究并产生很多分歧,但对于囚徒困境范式中是否存在分离效应以及其机制并没有一致的结果。本文对囚徒困境中的分离效应进行了验证性实验,虽然整体结果上与Shafir与Tversky(1992)的结论相吻合,但被试专业背景对结果有显著效应。同时,按照Lambdin和Burdsal(2007)对分离效应的操作定义,结果发现分离效应没有出现,文章对其原因进行了讨论。     

An examination of the construct validity of posttraumatic stress disorder with veterans using a revised criterion set

Ongoing concerns exist in the literature regarding the construct of posttraumatic stress disorder (PTSD) and how to best conceptualize and measure this disorder. We compared the traditional DSM-IV PTSD symptom criteria (i.e., symptoms from clusters B, C, and D) to a revised criterion set that omits overlapping mood and other anxiety symptoms on PTSD prevalence, PTSD diagnostic caseness, associated psychiatric comorbidity, functional status, and structural validity using a cross-sectional, multi-site primary care sample of 747 veterans. After removing items theorized to overlap with mood and other anxiety disorders, PTSD prevalence was identical using both criterion sets (i.e., 12%). Overall, there were few statistically significant differences in PTSD caseness, associated psychiatric comorbidity, functional status, and structural validity across the two diagnostic criterion sets. These data provide further support that removing items that overlap with other psychiatric disorders does not significantly impact the prevalence of PTSD, its associated comorbidity and functional impairment, or its structural validity. Although the revised criterion set represents a more parsimonious model, the current study findings generally support the strong construct validity of PTSD. The implications of these study findings for research and clinical practice are discussed.     

Generalizability of interest structure to China: Application of the Personal Globe Inventory

Two Chinese samples of the high school students (N=721) and the college students (N=943) were administered a translated version of the Personal Globe Inventory (PGI, Tracey, 2002), and the responses were examined with respect to their structure. Results of separate factor analyses demonstrated that there were three substantive factors: People/Things, Data/Ideas, and Prestige, similar to the structure of the PGI. The fit of the data to the PGI spherical model and the circular model of eight and six (i.e., RIASEC) types were examined using the randomized test of hypothesized order relations. The results demonstrated that the spherical model and the eight-type model fit the Chinese data equally well as data from the United States. However, unlike the Japanese results, Holland's six-type model fit the data as well as the eight-type model in the present study. No structure differences were found in the high school and the college samples or across gender within the high school and the college samples. The results support the structural validity of the PGI in Chinese applications.     

Maslow and Miller: An Exploration of Gender and Affiliation in the Journey to Competence

This article shows that although neither Abraham Maslow nor Jean Baker Miller reference each other in their writings, they are following different paths to the same conclusion: competence proceeds from connection. Miller and Maslow both describe a developmental model that applies equally to women and men. The conclusion of the authors of this article is that there is no need for separate developmental models for men and women because all self‐actualization and optimum mental health evolves from affiliation.
