Masculinity and femininity in twin children: genetic and environmental factors

Genetic and environmental origins of individual differences in masculine and feminine personality attributes were investigated in a sample of 38 monozygotic and 32 dizygotic twin pairs (total N = 140) during pre- and early adolescence. Self-report measures of both masculine and feminine characteristics were obtained for each child using 2 standardized instruments: the Children's Personality Attributes Questionnaire (CPAQ) and the Adolescent Self-Perception Inventory (ASPI). Multivariate biometrical analyses revealed significant genetic influences in all measures, accounting for 20%-48% of the observed variation in each. Environmental influences, which explained the remaining 52%-80% of variance in masculinity and femininity, were apparently specific to each individual and not shared by members of the same twin pair. The results underscore the importance of considering both genetic and environmental factors in gender-role development, particularly in studies of family resemblance.     

Assessment of symptoms in adult survivors of incest: a factor analytic study of the Responses to Childhood Incest Questionnaire

Although research has established the long-term damaging effects of incest, these efforts have suffered from the lack of valid, standardized assessment instruments. The present study reports on the construction and factor validation of the Response to Childhood Incest Questionnaire (RCIQ), a self-report instrument that assesses a range of commonly reported symptoms experienced by adult survivors of incest. A clinical population of 104 adult women who had experienced childhood or adolescent incest completed the RCIQ. A factor analysis of the RCIQ items revealed seven factors which corresponded to hypothesized stress response themes experienced by survivors of traumatic events. These factors include vulnerability and isolation, fear and anxiety, anger and betrayal, reaction to the abuser, sadness and loss, and powerlessness. In addition, four factors corresponded to the diagnostic criteria for post-traumatic stress disorder: intrusive thoughts, avoidance and intrusive emotions, detachment, and emotional control and numbness. The usefulness of the RCIQ as a pre- and post-treatment measure and the need for further research is discussed.     

The role of signaled periods of nonreinforcement in responding on a random schedule in autoshaping

Little responding develops to a conditioned stimulus (CS) that is placed in a random relation to an unconditioned stimulus (US). However, if the USs not preceded by that CS are themselves signaled by another stimulus, then the CS does come to elicit responding. This result has been attributed (e.g., by Durlach, 1983) to the signal’s blocking of conditioning to background cues that otherwise would prevent conditioning of the CS. However, Goddard and Jenkins (1987) have suggested the alternative that signaling the USs promotes responding due to the adventitious creation of periods of signaled nonreinforcement. Two experiments were conducted to assess this alternative, involving an autoshaping preparation in pigeons. In Experiment 1, little responding to a keylight CS presented in a random relation to a food US occurred, despite the explicit presentation of a discrete noise signaling periods of no food in the intertrial interval (ITI). Experiment 2 was designed to replicate the procedure of Goddard and Jenkins, in which an auditory stimulus extended throughout the ITI of a random schedule, terminating only prior to extra USs and during the CS. Contrary to their findings, little responding developed to the target CS. However, responding did develop when the sound-free period occurred only prior to the extra USs. These results offer little support for the hypothesis that signaled periods of nonreinforcement promote responding on random schedules. However, they are consistent with the view that signaling of ITI USs acts by preventing conditioning of potentially competitive background cues.     

Gender differences in the academic career

This study examines sources of satisfaction, indicators of stress, academic performance, and reward structure in the academic careers of male and female faculty at a major midwestern state university. Faculty pairs were selected from five academic divisions. A total of 58 matched pairs were identified. Of these, 63 faculty responded, yielding data for 23 matched pairs. Subjects were mailed the Academic Career Development Survey, consisting of 144 items. Results indicated that self-reported physical and mental health, and professional and personal life satisfaction were high for both males and females. Both males and females placed high importance on their career and on marriage/other intimate relationships; however, both reported high levels of dissatisfaction with these factors. Gender differences were found in both satisfaction and type of stress reported; no gender differences were found in composite teaching and research performance indices. Salary data, obtained for 42 matched pairs, indicated similar salary levels for men and women. Results were discussed with respect to prior research on gender differences and the academic career.     

Mother-Toddler Problem Solving: Antecedents in Attachment, Home Behavior, and Temperament

In a widely cited study, Matas, Arend, and Sroufe showed that mother-toddler interaction during problem solving at age 2 years was related to the child's prior attachment security. The current study asked (1) whether an independent laboratory could replicate this attachment finding, and (2) whether problem-solving interactions relate to mother-child interactions observed at home and to child temperament measured at 6, 13, and 24 months. Replicating Matas et al., secure dyads worked more competently, and mothers showed better quality of assistance and supportive presence. Mother-child home interaction also predicted problem solving: positive involvement at home predicted effective, unconflicted problem solving. Negative control at home did not predict problem-solving interaction. Unadaptable temperament was generally related to dependency in problem solving. Several patterns of correlations appeared to be mediated by sex of child, e.g., difficult temperament in boys predicted more effective, unconflicted problem solving, while for girls it predicted more conflict.     

Developing guidelines for HIV antibody testing among victims of pediatric sexual abuse

The incidence of human immunodeficiency virus (HIV) infection acquired by children through sexual abuse is presently unknown. A telephone survey of 63 practitioners of pediatric sexual abuse (PSA) assessment in the five U.S. regions with highest prevalence of HIV infection was conducted to determine the present status of guidelines for HIV antibody testing of PSA victims. No formal protocol was used by any of those surveyed, and a literature review found no existing guidelines for HIV antibody testing of PSA victims. A standard set of clinical situations was presented to practitioners to assess whether a consensus exists of indications for HIV antibody testing of abused children. Seven clinical profiles with 12 criteria were presented including HIV antibody status, AIDS/ARC clinical profile, and behavioral profile of the assailant; clinical profile of the victim; pre-assault victim behavioral profile compatible with high risk of HIV infection (exclusively adolescents); parent/guardian anxiety/psychosocial profile; and profile of the assaultive act with respect to potential transmissibility of HIV. We found an 85% or greater consensus for 6 testing criteria, and based upon these propose an interim set of HIV antibody testing guidelines for PSA victims. There was no consensus about five testing criteria, but their frequent citation merits further consideration. Clinical application of interim guidelines and design of prospective studies to quantitatively evaluate them are reviewed.     

Long-term Practicals in Chemistry in the First-cycle Engineering Curriculum

In 1974–75 at the K.U.Leuven Project Work as Practicals was started in the first-cycle engineering curriculum aiming at (1) the integration of separate teaching items and 7lpar;2) the integration of theoretical and practical or numerical aspects of those items. After 4 years the evaluation of it was more than satisfactory. The teaching team of the Chemistry course has integrated this system of practicals into their normal chemistry practicals. In this way more students 7lpar;currently only 20%) would be able to profit from the new education curriculum, now called ‘Long-term Practicals’. About 20%of the sophomore student volunteers are working for about 15 hours spread over 5 weeks at a mini-research subject in close contact with the members of the teaching team, using the instruments of the Chemistry Division, reading the literature, writing a report after the practical work, with discussion and evaluation of the work with their team-leader. To make it possible that all the sophomore students (400 students in 1987)could profit from this new education system, the physics, mechanics, mathematics, etc. practicals have to adapt to the same integrated practical system.     

Staff Self‐Appraisal at the Departmental Level: A Case Study

The introduction of academic staff appraisal in higher education institutions in Australia will require a considerable expansion in staff development facilities. An important issue will be the relative emphasis to be placed upon central staff development units as against structures at the faculty or departmental level. This case study, conducted at Macquarie University and aimed at improving teaching in higher education, explores the Self‐Appraisal Workshop as one such structure and suggests that it provides a very useful format at the faculty or departmental level because it brings together people teaching similar course units. As a result it is easier to integrate aspects such as curriculum design, assessment policies, academic content and teaching methods, than it is at the central level where staff development workshops usually have a cross‐faculty mix. An evaluation, based upon student ratings of teaching, interviews and staff reflection on the process, suggests that the Self‐Appraisal Workshop is a valuable technique for staff appraisal and development.     

Salary comparisons: New methods for correcting old fallacies

Institutions of higher education place high priority on ensuring that their faculties are adequately paid. Since gauging the adequacy of compensation is a problem of relative measure, this assessment is usually performed by comparing university-level average salaries for a group of peer institutions. Often the potential distortions caused by differences in the rank mix of the faculty are forestalled by comparing average salaries for each of the four ranks. However, few if any institutions take similar steps to prevent the skewing of averages owing to differences in cost of living, differences in distribution of faculty in academic year and twelve-month appointments, and differences in the configuration of the faculty over disciplines. This paper shows that salary comparisons that do not compensate for these variation in staff mix are seriously flawed. A recommended methodology is demonstrated.
