Expectations about the future and the emotional consequences of perceiving prejudice

Three studies tested the hypothesis that possessing a pessimistic outlook on life moderates the effects of perceiving sexism on emotions and self-esteem. Across all studies, a pessimistic outlook on life (either dispositionally held or experimentally induced) served as a source of emotional vulnerability among women (Studies 1-3) and men (Study 1) faced with evidence of sexism directed against their gender group. Study 3 demonstrated that one's outlook on life influences emotional adjustment to prejudice through the cognitive appraisal process. Relative to optimists, pessimists appraised sexism as more stressful and believed they possessed fewer resources for coping with it. This research emphasizes the importance of examining sources of vulnerability and resilience in understanding emotional responses to prejudice.     

Consensus conference on environmental values in radiation protection: a report on building consensus among experts

During the fall of 2001 (October 22–25), The Norwegian Radiation Protection Authority (NRPA) and the Agricultural University of Norway arranged a consensus conference on the protection of the environment against ionising radiation. The motive for the conference was the need to study the ethical and philosophical basis for protection of nature in its own right. The conference was funded by Nordic Nuclear Safety Research (NKS), in cooperation with the International Union of Radioecology (IUR). The National Committee for Research Ethics in Science and Technology (NENT) was hired as facilitators for the consensus process. This paper will give a brief outline of the aims and method of the conference, distinguishing these from other kinds of consensus conferences. The paper ends with some general reflections on the appropriateness of seeking consensus on ethics-related issues among experts.     

“work ethic” in pigeons: Reward value is directly related to the effort or time required to obtain the reward

Stimuli associated with less effort or with shorter delays to reinforcement are generally preferred over those associated with greater effort or longer delays to reinforcement. However, the opposite appears to be true of stimuli thatfollow greater effort or longer delays. In training, a simple simultaneous discrimination followed a single peck to an initial stimulus (S+_FR1 S−_FR1) and a different simple simultaneous discrimination followed 20 pecks to the initial stimulus (S+_FR20 S−_FR20). On test trials, pigeons preferred S+_FR20 over S+_FR1 and S−_FR20 over S−_FR1. These data support the view that the state of the animal immediately prior to presentation of the discrimination affects the value of the reinforcement that follows it. This contrast effect is analogous to effects that when they occur in humans have been attributed to more complex cognitive and social factors.     

Acetaminophen effects on behavioral thermoregulation in albino rats

Acetaminophen (N-Acetyl-p-aminophenol) was administered intraperitoneally to 15 Sprague-Dawley rats partitioned into 3 studies (5 rats per study) using a within subjects, repeated-measures reversal design. Behavioral thermoregulation was assessed in a cold Skinner Box using 5-sec. exposures of microwave radiation [Specific Absorption Rate = 0.34 Watts/kg/(mW/cm2)] as reinforcing stimuli under a fixed-interval 2-min. schedule of positive reinforcement. Doses of 10, 20, 30, 40, and 50 mg/kg (in solutions of 1%, 2%, 3%, 4%, and 5%) acetaminophen showed stable rates of operant responding for heat compared with significant changes in rates for comparable doses of aspirin in a 1993 study by Vitulli, et al. Weight reductions and temperature increases varied significantly with before-session and after-session measures, respectively. 1994-95 biochemical data of Murphy, et al. from humans following aspirin or acetaminophen ingestion which affect thermoregulation and sleep patterns are discussed in conjunction with behavioral data from rats.     

Wie können wir in das psychodynamische Erstinterview einführen?

We reflect on which traditional texts are suitable for the introduction into psychodynamic thinking for bachelor students in the faculty of psychology. We come to the conclusion that the use of works known and individually valued by the students from the world and/or trivial literature are suitable to allow students to carry out fictive preliminary conversations with their heroes from novels or films.     

Some properties of binormamin

Three properties of the binormamin criterion for analytic transformation in factor analysis are discussed. Particular reference is made to Carroll's oblimin class of criteria.The research reported in this note was supported in part by the Program in Applied Mathematics and Statistics. National Science Foundation, and by the National Institute of Education, Department of Health, Education, and Welfare.     

Image and anti-image covariance matrices from a correlation matrix that may be singular

Following the work of Tucker, Cooper, and Meredith, image and anti-image covariance matrices from a correlation matrix that may be singular are derived.     

EVALUATION OF A SOCIAL INTERACTION COACHING PROGRAM IN AN INTEGRATED DAY-CARE SETTING

We used a multiple baseline design across teachers (with a reversal phase for 1 teacher) to evaluate the direct and indirect effects of a structured coaching procedure on the teaching behaviors of 3 day-care teachers. Structured coaching preceding daily caregiver routines resulted in (a) substantial increases in adult delivery of behavioral support of social interaction during group activities with 2- and 4-year-old children and (b) marked collateral increases in positive interactions of socially withdrawn children. Long-term maintenance effects were demonstrated by both the teachers and target children, and social validity measures indicated that the teachers rated coaching very positively on several dimensions. The results are discussed in relation to in-service training of day-care staff, the concept of coaching as a setting event, and the dissemination of teaching technology related to social interaction of young children.     

Coefficients alpha for components

The formula for coefficient alpha for a component is developed. Kaiser's special formula for coefficient alpha for a principal component and the Kaiser-Guttman Rule for the "number of components" are mentioned. A numerical example is added. It is conjectured that the sum of coefficients alpha is invariant under orthogonal rotation.     

Hurricane Andrew: Psychological distress among shelter victims

This study examined psychological distress and functioning among Hurricane Andrew victims who lost their homes and were living in shelters. Four and one-half weeks after Hurricane Andrew struck southern Florida, 89 (45 males, 44 females) Blacks, Hispanics, and Whites completed a questionnaire. The questionnaire asked for information about psychological and psychophysiological symptoms, use of mental health services, coping responses, and extent of preparation for the storm. The findings suggest that loss of home and property were related to distress and depression. About one-quarter of the sample were moderately depressed. Over one-third of the sample reported experiencing psychological and psychophysiological distress. Approximately one-half of the subjects did not take the hurricane warnings seriously. White subjects began preparing earlier for the storm, and evacuated their homes more frequently than did Black subjects. Implications of the findings and future research directions are discussed.
