Locus of control and smokeless tobacco use among adolescents

Seventh-grade students from two school districts in rural North Carolina were surveyed to determine the prevalence and correlates of smokeless tobacco use. The survey was carried out as part of a larger project intended to study prevalence of "risky" behaviors, specifically alcohol and tobacco use. Data were collected from 322 students: 49% male, 36.6% nonwhite. Of those reporting use of smokeless tobacco (11.4%), virtually all were male; most reported weekly use, with a small proportion (1.3%) reporting daily use. Locus of control of "occasional" users was significantly more internal than those reporting "regular" use (p less than .05).     

Assumed Similarity of Attitudes About AIDS Among Gay and Heterosexual Physicians

Heterosexual and gay physicians indicated their own attitudes on several issues related to the AIDS epidemic and attributed a position on each issue to the target group "most people." The heterosexual physicians' attitudes were more negative than the gay physicians' attitudes. Both groups judged that "most people" hold attitudes more negative than their own. The distance between own and attributed position as much greater for the gay individuals. This distance effect was due primarily to differences in self-ratings between the two groups. Own and attributed position correlated positively for each group of physiaans. Additionally, the tendency to assume similarity was marginally stronger for heterosexuals with high than low homophobia. Theoretical interpretation is presented.     

Exemplary job analysis systems in selected organizations: A description of process and outcomes

Job analysis is an important aspect of human resource management. This study was conceived to further our understanding of how job analysis may best be used to enhance the variety of human resource management activities that rely on it. Nine geographically dispersed organizations, carefully selected on the basis of their exemplary job analysis functions, were each visited and their job analysis functions studied for a period ranging from one to three days. These organizations represented a wide range of industries. We found that job analysis functions are typically highly centralized and part or all of these functions are often housed in a unit dealing with compensation. The idea of a fully integrated personnel system based on a comprehensive job analysis data base is not quite ready for widespread adoption. However, a multipurpose approach, designed to serve several applications, is feasible to develop. Little progress has been made in estimating the costs of job analysis functions. Rudimentary cost estimates prepared by us on anad hoc basis revealed that the annual costs for job analysis functions ranged from $150,000 to $4,000,000 with a median of$280,000.     

The Costs and Benefits of Optimistic Explanations and Dispositional Optimism

Explanatory style and dispositional optimism have been linked to physical health. In this issue, Peterson and Seligman and Carver and Scheier review an impressive series of studies which together suggest that there may be health risks associated with attributing bad outcomes to internal, stable, and global causes and with failing to maintain a generalized expectancy for good outcomes. We attempt to broaden the scope of these studies by describing the situational constraints on the observed relations and by presenting evidence that there may be health risks, as well as benefits, associated with dispositional optimism and an optimistic explanatory style.     

Behavioral stress impairs long-term potentiation in rodent hippocampus

A number of hormones secreted from the pituitary-adrenal system during stress affect learning and memory processes. The phenomenon of hippocampal long-term potentiation (LTP) is viewed by many as a putative mechanism of memory storage and has proved a most valuable model for study of neuronal plasticity at the cellular level. The present study was conducted to investigate the possibility that stressful events which occur prior (in vivo) to the preparation of brain slices may influence the electrophysiology of the in vitro hippocampal explant when tested for LTP. Adult male rats (Long-Evans male X Sprague-Dawley female) were pair-housed 1 week prior to testing. One animal in each pair was either placed in a restraining tube for 30 min and received no tail shocks (Restraint) or placed in a restraining tube and received tail shocks (1 microA, 1 s) every minute for 30 min (Restraint + Shock). The other animal in each pair was taken directly from the home cage and received no restraint or tail shock (Control). In vitro hippocampal slices were then prepared immediately from these animals according to standard methods. Our results demonstrate a marked impairment of LTP in hippocampal explants taken from rats exposed to stress. The significance of this result with respect to cellular mechanisms underlying the relationship between stress, cognition, and learning is discussed.     

Techniques for handling resistances in group psychotherapy with severely disturbed patients

There has been an increased interest in recent years in the treatment of those with severe psychopathology through application of object relations theory and modern ego psychology. Yet, for the past 20 years, such patients have been treated in day hospitals where rehabilitation and socialization concepts have been employed. This paper integrates some of the advances in psychoanalytic theory with more established methods of milieu therapy. In the patients studied, the therapists noted the presence of severe envy, dependency, passivity and with-holding, an intolerance for aggression along with an intransigent, paranoid-schizoid position. The techniques described here worked through the effects of these resistances so that the patients could use the psychotherapy group, and the entire milieu, more constructively than they did before.Ruthe Feilbert-Willis, C.S.W. was formerly Senior Social Worker in the Adolescent and Adult Day Hospital at The New York Hospital-Cornell Medical Center, in White Plains, New York.He was a psychiatric resident at The New York Hospital-Cornell Medical Center, in White Plains, New York, during the time the clinical work of this paper was undertaken.     

Joint-space analysis of “pick-any” data: Analysis of choices from an unconstrained set of alternatives

Social and naturally occurring choice phenomena are often of the pick-any type in which the number of choices made by a subject as well as the set of alternatives from which they are chosen is unconstrained. These data present a special analytical problem because the meaning of non-choice among pick-any choice data is always ambiguous: A non-chosen alternative may be either unacceptable, or acceptable but not considered, or acceptable and considered but not chosen. A model and scaling method for these data are introduced, allowing for this ambiguity of non-choice. Subjects are represented as points whose coordinates are proportional to the centroids of the points representing their choices. Alternatives are represented at points whose coordinates are proportional to the centroids of the points representing subjects who have chosen them. This centroid scaling technique estimates multidimensional joint spaces from the pick-any data.I am indebted to John Baird, Clyde Coombs, David Eames, John Hunter, Michael J.

The effect of debriefing on laboratory induced helplessness: An attributional analysis1

Debriefing was assessed as means of reversing helplessness deficits through reattribution. Fifty-five subjects listened to escapable or inescapable tones. One inescapable group, prior to anagrams, was debriefed regarding noise uncontrollability. A second inescapable group was administered anagrams by a different experimenter. While exposure to inescapable noise led to performance deficits, switching experimenters obviated these deficits. Debriefing actually facilitated anagram performance. All inescapable subjects—debriefed or not—attributed their lack of control on the noise task to experimenter interference, casting some doubt on reattribution as an explanation of debriefing's effects. Results were discussed in terms of the reformulated learned helplessness model and the ethical implications of debriefing in learned helplessness research.
