ABOUT THE AUTHORS

Work satisfaction, self‐esteem, and alienation measures were obtained from white males in three service occupations (bartenders, barbers, and mailmen) at different levels of the occupational prestige hierarchy. While we found an overall positive relationship between work satisfaction and occupational prestige, this only held for variables where societal reference groups were forced upon the respondents. Such findings suggest that the relationship between work satisfaction and occupational prestige is less absolute than usually suggested by the literature. Hypotheses from the literature arguing for a direct relationship between occupational prestige and alienation were not supported by our data. We conclude that sociologists probably overestimate the salience of work and occupational prestige for the working class.     

Web-based nutrition education for college students: Is it feasible?

College students have poor nutrition habits and often exhibit at-risk weight control behaviors; yet, health promotion efforts on campuses often target other risk behaviors such as alcohol and tobacco use. The goal of this study was to determine program content and examine the feasibility of a web-based nutrition education program for college students using innovative applications of tailoring, targeting and personalization of information. Comprehensive program planning entailed three phases: focus groups and use of concept mapping methodology, prototype web program development, and feasibility testing of the prototype. Results of concept mapping suggested that students and experts agreed on the relative importance of the major content areas unique to the college audience. A prototype web program, informed by health promotion theories, was developed and evaluated. Students and college health professionals participated in the feasibility evaluation, which included acceptance and usability testing of the prototype. Mean scores were computed for the acceptance ratings that indicated that the prototype web program was not only feasible, but also compelling and relevant for the college audience. In conclusion, a tailored, web-based interactive nutrition program could potentially be used to provide individualized nutrition information to encourage college students to adopt healthy eating behaviors.     

Effect of Dyadic Context on Judgments of Rapport: Dyad Task and Partner Presence

The present studies investigated the effects of dyadic context on judgments of nonverbal behavior associated with rapport. As predicted, the task performed by a dyad, the visible presence or absence of both dyad members, and the sex of the observer affected observer judgments of responsiveness, friendliness, dominance, critical scrutiny, polite sympathy, and high status. The results suggest that dyadic context affects judgments of dyad members' facilitation of rapport by both constraining dyad behavior and affecting observer perception: (a) Dyad members received higher judgments on person-focused behaviors when engaged in a discussion as compared to a puzzle; (b) Visible presence of an interaction partner led observers to see a dyad member, on the whole, as inhibiting rapport in the interaction; and (c) Female observers perceived dyad members to exhibit more rapport-facilitating behavior. These results have major implications for the way rapport and person perception research is conducted and for understanding interpersonal perception in everyday life.     

Perfect Forward Simulation via Simulated Tempering

Several authors discuss how the simulated tempering scheme provides a very simple mechanism for introducing regenerations within a Markov chain. In this article we explain how regenerative simulated tempering schemes provide a very natural mechanism for perfect simulation. We use this to provide a perfect simulation algorithm, which uses a single-sweep forward-simulation without the need for recursively searching through negative times. We demonstrate this algorithm in the context of several examples.     

Medcamp's Effect on Junior High School Students' Medical Career Self-Efficacy

Medcamp, a 3-day problem-based career intervention for students entering the 9th grade, implemented each of the 4 antecedents for self-efficacy. Ten boys and 35 girls participated in Medcamp; of these, 35 completed and returned the Medical Career Self-Efficacy Scales (developed by the authors for their study) both at the beginning and at the end of the program. Three scales measured specific self-efficacy (tasks students had performed during Medcamp), related self-efficacy (other tasks students would complete by the second year of medical school), and general self-efficacy (included lifestyle variables and study habits). Results demonstrated significant increases in self-efficacy on all 3 scales.     

A psychodynamic approach to the treatment of pathological gambling: Part I. Achieving abstinence

A psychodynamic approach emphasizes the meaning and consequences of one's behavior. After a brief review of the literature, the authors present the first of a two-part model for psychodynamic psychotherapy with pathological gamblers. In this first phase, the immediate goal is abstinence, and five strategies for obtaining it are discussed. These consist of 1.) breaking through the denial 2.) confronting omnipotent defenses 3.) interrupting the chasing cycle 4.) identifying reasons for gambling, and 5.) motivating the patient to become an active participant in treatment. An argument is made for integrating a traditional psychodynamic approach with an addictions model.     

Scaling limits for the transient phase of local Metropolis–Hastings algorithms

Summary.  The paper considers high dimensional Metropolis and Langevin algorithms in their initial transient phase. In stationarity, these algorithms are well understood and it is now well known how to scale their proposal distribution variances. For the random-walk Metropolis algorithm, convergence during the transient phase is extremely regular—to the extent that the algo-rithm's sample path actually resembles a deterministic trajectory. In contrast, the Langevin algorithm with variance scaled to be optimal for stationarity performs rather erratically. We give weak convergence results which explain both of these types of behaviour and practical guidance on implementation based on our theory.
