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.     

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.     

Relationships of deployment and combat experiences to postdeployment negative health conditions among Army National Guard soldiers

An interest of researchers and practitioners has been postdeployment adjustment of returned soldiers, though the primary focus has been investigating the prevalence of psychiatric conditions. Less attention has been paid to nonclinical conditions, which still have posed significant adjustment problems for soldiers, in particular, for reserve soldiers who revert back to civilian life, family, and employment. The present study examined the occurrence of postdeployment problems among returned Army National Guard soldiers (N = 4,567 in 50 company-sized units). Survey items reliably indicated 7 problem areas. Highest prevalence of problems was being angry (35.9%) and being unable to sleep (43.3%), followed by alcohol abuse (25.1% reported 5 or more drinks in 1 day). Longer deployment lengths were associated with troubled relationships and aggression toward the significant other adult and children in the household. More deployments were associated with aggression toward household children. Self-reported general combat trauma and having killed or wounded someone were associated with all problem areas. Findings are discussed relative to how combat exposure likely alters soldiers’ perceptions and behaviors, including feelings of loneliness and isolation, and risk-taking behaviors of alcohol abuse and aggression toward others.     

The relation of organizational process orientation to effectiveness and efficiency in elementary public schools

Organizational psychology has identified four recurrent organizational models (rational goal, open systems, human relations, and internal processes), each placing different emphases on internal and external organizational processes. Using a sample of 122 elementary schools in a large suburban school district located outside a metropolitan area, the present study examined the relation of school emphases on internal and external processes to school effectiveness and efficiency. Consistent with hypotheses, inefficient schools (lower-than-average student achievement test scores, adjusted by the percentage of students enrolled in the free and reduced-price meal program and per-pupil expenditures) were identified by the human relations model or as inward-directed with emphasis on the quality of student-school staff interpersonal relationships, by higher levels of student enjoyment, and by smaller student enrollments and smaller student-faculty ratios. Contrary to expectation, results showed that effective schools (higher-than-average student achievement test scores) were best described in terms of the rational goal model or as outward-directed, with emphasis on involving and empowering parents and on internal structure, control, and inflexibility (i.e., more school order and discipline). Results are discussed in terms of the broader organizational literature, specifically, competing organizational value orientations, effects of organizational structure and member characteristics on organizational process orientation, and the use of organizational process orientation as means to achieve organizational effectiveness and efficiency.     

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.     

Visual input regulates circuit configuration in courtship conditioning of Drosophila melanogaster

Courtship and courtship conditioning are behaviors that are regulated by multiple sensory inputs, including chemosensation and vision. Globally inhibiting CaMKII activity in Drosophila disrupts courtship plasticity while leaving visual and chemosensory perception intact. Light has been shown to modulate CaMKII-dependent memory formation in this paradigm and the circuitry for the nonvisual version of this behavior has been investigated. In this paradigm, volatile and tactile pheromones provide the primary driving force for courtship, and memory formation is dependent upon intact mushroom bodies and parts of the central complex. In the present study, we use the GAL4/UAS binary expression system to define areas of the brain that require CaMKII for modulation of courtship conditioning in the presence of visual, as well as chemosensory, information. Visual input suppressed the ability of mushroom body- and central complex-specific CaMKII inhibition to disrupt memory formation, indicating that the cellular circuitry underlying this behavior can be remodeled by changing the driving sensory modality. These findings suggest that the potential for plasticity in courtship behavior is distributed among multiple biochemically and anatomically distinct cellular circuits.
