Organizational Citizenship Behaviors: Achievement Orientation and Personality

The current study investigated the effects of personality variables as antecedents in predicting Organizational Citizenship Behaviors (OCBs), with the covenantal relationship as a mediating variable. 284 retail sales employees were administered 4 personality tests, a composite measure of the covenantal relationship, and a measure of citizenship behavior. Value for achievement, agreeableness, and conscientiousness predicted five types of organizational citizenship. Extraversion was not predictive across all citizenship behaviors. Implications for the relationship between personality and citizenship are discussed.     

The Effectiveness of a REBT Training Program in Increasing the Performance of High School Students in Mathematics

The efficacy of an REBT-based skill training program on the mathematics performance of disadvantaged black eleventh graders enrolled in Upward Bound was examined. Fifty-six students (18 males and 37 females) were randomly assigned to Perception Analysis Training (PAT) or an attention control group (ACG). The two groups met at the same hour each week for eight-weeks. PAT consisted of instruction in the application of RET strategies to the management of emotions that interfere with the development of proficiency in mathematics. ACG group members discussed films pertaining to career and personal development. Pre-test results confirmed a relationship between beliefs and mathematics achievement. Three measures of problematic beliefs concerning mathematics were significantly correlated (p>.01) with high school math grades and performance on the California Achievement Test-Math (CAT). At post-test PAT participants were less committed to self-defeating beliefs regarding mathematics than AGC members. ANCOVAs showed that PAT students made significantly greater pre- to post-test gains in their mathematical performance than control group members. PAT group members out performed AGC subjects in terms of Upward Bound math grades (ES=0.61; p >.0008), high school math grades (ES = 1.09; p>.0001), and scores on the CAT (ES=0.40; p >.02).     

Tripartite Mushroom Body Architecture Revealed by Antigenic Markers

We have explored the organization of the axonal lobes in Drosophila mushroom bodies by using a panel of immunohistochemical markers. These markers consist of antibodies to eight proteins expressed preferentially in the mushroom bodies: DAMB, DCO, DRK, FASII, LEO, OAMB, PKA RII, and RUT. Previous to this work, four axonal lobes, two projecting dorsally (α and α′) and two medially (β and γ), had been described in Drosophila mushroom bodies. However, our analysis of immunohistochemically stained frontal and sagittal sections of the brain revealed three medially projecting lobes. The newly distinguished lobe, which we term β′, lies along the dorsal surface of β, just posterior to γ. In addition to resolving a fifth lobe, our studies revealed that there are specific lobe sets defined by equivalent marker expression levels. These sets are (1) the α and β lobes, (2) the α′ and β′ lobes, and (3) the γ lobe and heel (a lateral projection formed by a hairpin turn of some of the peduncle fibers). All of the markers we have examined are consistent with these three sets. Previous Golgi studies demonstrate that each mushroom body cell projects one axon that branches into a dorsal lobe and a medial lobe, or one unbranched axon that projects medially. Taken together with the lobe sets listed above, we propose that there are three major projection configurations of mushroom body cell axons: (1) one branch in the α and one in the β lobe, (2) one branch in the α′ and one in the β′ lobe, and (3) one unbranched axon projecting to the heel and the γ lobe. The fact that these neuron types exhibit differential expression levels of a number of mushroom body genes suggests that they may have corresponding functional differences. These functions may be conserved in the larvae, as several of these genes were expressed in larval and embryonic mushroom bodies as well. The basic mushroom body structure, including the denritic calyx, peduncle, and lobes, was already visible by the late stages of embryogenesis. With new insights into mushroom body organization, and the characterization of markers for developing mushroom bodies, we are beginning to understand how these structures form and function.     

Measuring neighborhood context for young children in an urban area

Awareness of worsening conditions in urban areas has led to a growing interest in how neighborhood context affects children. Although the ecological perspective within child development has acknowledged the relevance of community factors, methods of measuring the neighborhood context for children have been quite limited. An approach to measuring neighborhood environments was tested using the average perceptions of caregivers of young children sampled from high- and low-risk block groups. Individual- and aggregate-level reliabilities and discriminant validity were acceptable for dimensions of neighborhood quality and change, participation in block organizations, disorder and incivilities, service usage and quality, and retaliation against adults. However, for measures of neighborhood interaction and the tendency of adults to intervene with children, there was virtually no agreement among respondents within block groups, resulting in poor aggregate reliability. A model of variability may be a more promising way of characterizing neighborhoods along these dimensions. This research was supported primarily by a grant from The Foundation for Child Development, as well as support from the Cleveland Foundation.     

Impulsiveness and risk-taking behavior: comparison of high-school and college students using the Barratt Impulsiveness Scale

The present study was undertaken in an attempt to determine the relationship of impulsiveness to risk-taking behaviors such as aggression, drug use, drunk driving and not wearing seatbelts among highschool and college students. The results of the study clearly demonstrate that high impulsives are involved in risk-taking behavior at a higher rate than low impulsive subjects. These findings suggest that high impulsive adolescents and young adults are at considerable risk of personal injury and present a potential source of injury to others. It is suggested that self-report questionnaires of impulsiveness might prove useful in the early identification of these high risk individuals. Once identified these individuals could be targeted for intensive educational interventions specifically designed to deal with their inability to delay gratification and general lack of impulse control.     

CHEMISTRY: WHAT DOES ONE NEED TO KNOW?

Abstract. The general knowledge and understanding that every teacher of religion and science should have relative to chemistry can be found in the answers to three major questions. In my own response to the first question, How did chemistry emerge as a discipline? I trace the origins, establishment, and subsequent historical significance of cosmology. I contend that chemistry is “the obvious, oldest science” and, as such, has played a key role among the sciences in agelong human efforts to understand reality. In my response to the second question, How do chemists currently view (cosmic) reality? I outline three prominent examples in support of my contention that chemistry, despite being “the obvious, oldest science,” is seen by some as playing only a tacit role in current efforts to (re)integrate religion and science. In my response to the third question, How do chemists currently view ultimate reality and meaning? I argue that “unifiers” in chemistry can also now play a key role in a reality revolution that is pointing humankind not only toward a possible historical (re) integration of religion and science but also toward a return to cosmology.     

The Amish: Perceptions of genetic disorders and services

Previous studies of the closed Amish population have proven to be valuable in the field of genetics, however they have not explored the Amish parents' opinions and attitudes concerning genetic conditions and services. This exploration is necessary in order to provide culturally sensitive health care to a population at an increased risk for certain genetic conditions. The purpose of the present study was to examine the Amish population's general knowledge of genetic disorders, services, and the terminology used in describing inherited conditions, as well as their attitudes toward medical care and ethical and reproductive issues. Information was obtained from 17 Amish families, 12 who had an incidence of a genetic condition and five who had one or more children with other special health care needs, during personal interviews conducted in their homes in Lancaster, Pennsylvania. Results of the interviews showed that the birth of an affected child did not deter subsequent reproduction, that the majority of the parents were never offered genetic counseling or prenatal testing, and that the parents are interested in understanding the cause of their children's problems and recurrence risks.     

Gender stereotypes are not accurate: A replication of Martin (1987) using diagnostic vs. self-report and behavioral criteria

Women and men (58 females and 42 males) reported whether they possess each of several stereotypic and neutral traits (self-report criterion) and recorded the percentage of each gender they believed display each trait (diagnostic). Observations of subjects (57 males and 49 females) discussing controversial topics yielded the behavioral criterion. (Approximately 81% of the total sample was European-American, 8% African-American, 2% Hispanic, 1% Asian, and the remainder of “other” ethnicity.) Gender differences were larger and more inaccurate in stereotypes (diagnostic) than in “reality” (self-report criterion), but behavioral criterion results were mixed. Difficulties in specifying criteria for “actual differences,” including behavioral criteria, and recent work related to C. L. Martin's [(1987) “A Ratio Measure of Gender Stereotyping,” Journal of Personality and Social Psychology, Vol. 52, pp. 489–499] paradigm (and results) are considered. Implications of results for the importance of replication and for research on accuracy of stereotypes are also discussed.
