A Case-Study of the Careers Service Placement Function

A number of models of the placement function of the Careers Service are presented. Various hypotheses generated by the models are tested, using data collected from Careers Service records. Specifically, a multivariate analysis is performed to show which personal and social characteristics are associated with a higher probability of being submitted for a permanent vacancy. The implications of the analysis for the Careers Service are discussed.     

Using the internet to extend training in team problem solving

A hybrid training approach, composed of both computer-mediated communication on the Internet and face-to-face meetings, was implemented. The goals were to examine whether such an approach (1) could be used to extend traditional, short-term training, and (2) would be perceived as useful by the trainees. A central element of the approach was thelinchpin expert, a trainer who served as a communication bridge on the Internet between a team of trainers and a team of trainees. A coding system was developed to analyze the content of the Internet messages. Logistic regression analysis revealed that two types of content were related to the trainees’ perceptions that the messages enhanced their expertise in team problem solving: (1) outcome feedback given to a trainee about a specific activity, and (2) the sharing of conceptual information. The trainees perceived face-to-face and computer-mediated communications with the linchpin expert as being important to their development of expertise.     

Measuring abuse stress and negative cognitive appraisals in child sexual abuse: Validity data on two new scales

The validity of two measures assessing degree of stress associated with child sexual abuse was examined in a sample of 48 girls who had been sexually abused. The Checklist of Sexual Abuse and Related Stressors (C-SARS) assessed negative life events that were part of or were related to the abuse, and the Negative Appraisals of Sexual Abuse Scale (NASAS) assessed negative cognitive appraisals of threat, harm, or loss associated with the abuse. Total scores for victim reports of both stressful events and negative appraisals were positively and significantly related to two other measures of abuse severity: therapist ratings of abuse stress and the number of types of sexual abuse reported. Stressful event scores were also related to aggressive behavior problems, sexual concerns, and total symptom scores on the Child Behavior Checklist. Negative cognitive appraisal scores were related to victims' self-reports of depression, anxiety, and posttraumatic stress symptoms, and to parent reports of child depression and total symptoms. Regression analyses indicated that there were significant effects of negative appraisals on internalizing symptoms when controlling for the level of stressful events experienced. The results suggest that negative life events and negative appraisals associated with sexual abuse are valid constructs that help account for variability in mental health outcomes among child victims. The implications of these results and future research directions in examining variable outcomes among sexual abuse victims are discussed.     

Some Thoughts on Language Use in Therapy

Drawing on the work of Ludwig Wittgenstein and his own experience as a therapist and educator/trainer, the author describes some of the issues involved in helping therapists to find their way out of various muddles and mazes that are deeply embedded in language.     

Discriminability and criterion differences between extraverts and introverts during vigilance

In a signal detection task introverts were better able than extraverts to distinguish between the signal and noise distribution (p < .001) and also set a higher criterion point for their responses (p < .01). The results show that superior vigilance in introverts reported by other investigators is due to two processes.     

FOCLAB: A language for computer-controlled psychology research

The FOCLAB system, a dialect of FOCAL, provides complete real-time experiment control and data acquisition capabilities in the area of experimental psychology. The language provides digital and analog input/output, graphics (including alphanumerics) on a refresh CRT, and a powerful set of time measurement operations. With these facilities FOCAL may be used in cognitive and operant, as well as psychophysiological research. FOCLAB will operate with either PDP-8 or PDP-12 systems, and can control most of the currently existing lab interface options for these computers. The system will operate on 8K core-only machines, as well as under OS/8.     

Adolescent Nonsmokers,Triers, and Regular Smokers' Estimates of Cigarette Smoking Prevalence: When Do Overestimations Occur and by Whom?1

The present study tested three assumptions often made by smoking prevention researchers and practitioners regarding the nature and causes of smoking prevalence estimates. Specifically, it is often assumed that (a) adolescent prevalence estimates of all levels of smoking are inflated, (b) youths at different stages of smoking onset all overestimate smoking prevalence, and (c) the predictors of these estimates are the same for youths at different stages of smoking onset. Measures of smoking behavior based on self-reports using a bogus pipeline procedure, estimates of cigarette smoking prevalence (trying behavior and weekly use), and reports of smoking in significant others were obtained by the same youths when they were in eighth and ninth grades. Results indicated that, taken over all youths, estimates of trying cigarettes were accurate, whereas estimates of weekly use were inflated. When responders were defined by their stage of smoking onset, either as a nonsmoker, trier, or regular smoker, analyses revealed that triers were accurate regarding prevalence estimates of trying, whereas non-smokers made gross underestimations and regular smokers made overestimations of trying. All groups of youths overestimated prevalence of weekly smoking. Analyses of variance revealed that both youths' smoking status and interpersonal smoking environment additively predicted prevalence estimates, and estimates of smoking prevalence were relatively higher in youths who began to smoke, or increased their levels of smoking, within the next year. Thus, previous assumptions were partially confirmed. Future research and prevention programming should focus more on regular smoking as the focus of normative smoking distortion effects and correction efforts.     

Completeness and conservative extension results for some boolean relevant logics

This paper presents completeness and conservative extension results for the boolean extensions of the relevant logic T of Ticket Entailment, and for the contractionless relevant logics TW and RW. Some surprising results are shown for adding the sentential constant t to these boolean relevant logics; specifically, the boolean extensions with t are conservative of the boolean extensions without t, but not of the original logics with t. The special treatment required for the semantic normality of T is also shown along the way.
