Dominance,sex, and leader emergence

A 3×2×2 incomplete factorial design was employed to test the effects of sex, dominance, and their interaction on leader emergence. The factors included dominance distribution (high/high, high/low, middle/middle), sex (male-female), and dyad composition (mixed sex-same sex). The subjects were all Caucasians and were pretested on the California Psychological Inventory Dominance Scale. The data revealed that dominance was a predictor of leader emergence in same-sex conditions where high-dominant individuals assumed the role of leader in much greater proportions than their low-dominant partners. In mixed-sex dyads, sex appeared to be a more potent predictor with males becoming leaders at levels greater than would be suspected given dominance levels.     

EFFECTS OF EXPLICIT TIMING ON MATHEMATICS PROBLEM COMPLETION RATES IN AFRICAN-AMERICAN THIRD-GRADE ELEMENTARY STUDENTS

A multiple baseline design was used to evaluate the effects of Van Houten and Thompson's (1976) explicit timing procedure on problem completion rates and accuracy levels in African-American third-grade students. During the explicit timing phase, students were told that they were being timed and were instructed to circle the last problem completed at each 1-min interval. Results showed that the explicit timing procedure increased problem completion rates. A decreasing trend in percentage of problems correct also occurred. Exploratory data analysis suggested that decreases in accuracy were not caused by the explicit timing procedure and did not occur in students who had attained high levels of preintervention accuracy. Discussion focuses on recommendations for educators who wish to use timing procedures to increase students' rates of accurate responding.     

The view of Islam from the monasteries of Palestine in the early cAbbasid period: Theodore Abū Qurrah and the Summa theologiae arabica

Christians in the Holy Land, and particularly members of the monastic communities in the Judean desert, were the first to compose original works of theology in Arabic. These writers presented the doctrines of the church in an idiom which was calculated to appeal to the understanding of any speaker of Arabic who was familiar with the Qur'an and with the thought of the early Muslim mutakallimin. From these texts there emerges a view of Islam which makes it dear that the writers very much consider themselves to be doing theology in dialogue. The article discusses the earliest Christian apology in Arabic; two works of Theodore Abu Qurrah; an early Summa Theologiae Arabica; and an essay in apologetics, provocatively entitled Kitab al‐burhan.     

Stage 2 processing and the divided-attention effect

In two experiments subjects performed a choice-reaction-time (CRT) task and a second task concurrently. The second task was a simple reaction-time task in Experiment 1 and sentence generation and recall tasks in Experiment 2. Both studies yielded two main findings: Performance of the second task was not affected by CRT memory load (one, two, or four items), and the requirement to perform the second task did not affect the rate of increase of CRT with memory load. The first finding indicates that the effect of memory load on CRT is attributable to memory scanning, or Stage 2 processing, and is not an artifact of the rehearsal demands of the CRT memory set. The second finding indicates that Stage 2 processing is not sensitive to division of attention between the CRT and a second task.     

Abstinence or control: The outcome for excessive drinkers two years after consultation

This report presents the two-year follow-up results for a sample of married male alcoholics who had been the subjects of a controlled treatment trial. Cumulative relapse curves for the two-year period were found to be similar in form to those which Hunt and Matarazzo (1970) have drawn for drug addicts, alcoholics and smokers. Outcome at 12 and 24 months were compared: changes from good to bad outcome, or vice versa, were rare. The degree of hardship reported by wives remained predictive of outcome two years later. Not all drinking reported at two years was uncontrolled. Of 26 men with a good outcome. 11 were agreed by husband and wife to be abstaining, and 10 were agreed to be controlling their drinking. Most of the latter had not shown lengthy periods of abstinence prior to resuming drinking. Controlled drinkers reported fewer symptoms at intake (morning drinking, shakes, secret drinking, hallucinations etc.), were more likely to have been sub-diagnosed as Alpha alcoholics (psychologically dependent), and were more likely to have been only briefly counselled. Abstainers reported more symptoms at intake, were more likely to be sub-diagnosed as Gamma alcoholics (physically dependent), and were more likely to have been intensively treated. These results suggest an interaction between degree of dependence, type of treatment, and goal of treatment. If confirmed by future research this would have strong implications for the planning of comprehensive alcoholism treatment services.     

An Intersectional Approach to the Glass Ceiling: Gender,Race and Share of Middle and Senior Management in U.S. Workplaces

A robust body of research examines factors affecting the likelihood that women experience increasing barriers to promotion in workplaces. However, limited research examines how racialized and gendered processes may intersect and work differently for racially and gender marginalized workers. Specifically, the processes relating to a worker’s ability to reach middle-level management positions (e.g., those managers who oversee a small group of employees) and senior-level management positions (e.g., CEOs and other executive positions) may vary based on workers’ race and gender. Using 2015 EEO-1 data collected by the U.S. Equal Opportunity Employment Commission (EEOC), we examine how the characteristics of a workplace affect Black men, Black women, White men, and White women’s share of middle- and senior-level management. We find Black women and Black men are strikingly under-represented in both middle and senior management in private-sector workplaces. Our results demonstrate that access to middle- and senior-management varies by the characteristics of the workplace and workers’ race and gender. Overall, our findings point to an important implication: Greater oversight of workplaces, including by the EEOC, is associated with marginalized race/gender groups having higher shares of management.

The relationship between STD locus of control and STD acquisition among adolescent girls

This longitudinal study examined adolescent girls' perception of control over sexually transmitted disease (STD) acquisition. Participants were asked questions regarding their perception of their STD locus of control (internal control; control by parents, partners, peers, and health care providers; and chance) at two waves of data collection. Of the 116 participants (mean age = 17 years), 82% were African-American and 18% were Caucasian. Responses to the measure of locus of control were significantly correlated across a 6-month interval. The responses regarding internal control, control by partner, and chance were not related to the acquisition of an STD in the next 6 months. Further, they were not influenced by an STD in the preceding 6 months. These results indicate that responses to a locus of control measure were stable over a 6-month period, and internal, partner, and chance locus of control perceptions seem to be neither determined by STD experience nor directly related to future STD acquisition. However, understanding an individual's locus of control may be helpful in providing appropriate counseling. Future research could examine how adolescent girls form their perceptions of control over STD acquisition.
