The distinction between work pace and working hours in the measurement of quantitative demands at work

During recent years many researchers have criticized the widely used scales on psychological job demands. For instance, they comment that in most cases different types of demand seem to be mixed in one measure. In this paper we analyse the scale on quantitative job demands in the recently developed Copenhagen Psychosocial Questionnaire (COPSOQ), with special emphasis on Differential Item Functioning (DIF). DIF refers to basic differences between groups of respondents, which may affect how they respond to questionnaire items. The data material for our study comprised a representative sample of Danish employees. The respondents were categorized into 32 specific jobs according to the International Standard Classification of Occupations (ISCO 1968). We analysed DIF with respect to the respondents' jobs with logistic regression analyses. These analyses showed that the items used in the original demand scale functioned very differently for different jobs in the population. The conclusion is that scales on quantitative demands are very sensitive to the choice of specific items. If many items on fast work pace and tempo are included in a scale, a number of blue-collar jobs will be identified as high-demand jobs. If, on the other hand, many questions on long working hours and overtime are included, the use of the scale will result in an entirely different picture. This issue has so far received little attention in occupational health psychology. The results have wide theoretical and methodological implications for research on quantitative job demands.     

Model influence functions based on mixtures

Influence functions are considered as diagnostics for model departures in parametric Bayesian inference. A baseline model density is expressed as a mixture; then the mixing distribution is perturbed. This is designed to engender perturbations which are plausible a priori. The influence of perturbations is measured for both Bayes estimates and their associated posterior expected losses. To assess the plausibility of perturbations a posteriori, an additional influence function is constructed for the Bayes factor comparing the perturbed and baseline models. The effect of perturbation on various estimands is incorporated in the analysis.     

ONE PERSPECTIVE ON THE MILAN SYSTEMIC APPROACH: PART II. DESCRIPTION OF SESSION FORMAT,INTERVIEWING STYLE AND INTERVENTIONS*

The Milan method of working with families includes a number of unique innovations. Among these are a pattern of creative teamwork that clearly separates the cognitive constructions of the therapist in contrast to the belief systems of the family, a style of interviewing that releases information latent in the family, and some novel interventions that facilitate the family's capacity to discover its own non-symptomatic solutions.     

Who will lead?

A recent survey conducted by the UCLA Center for Health Services Management and the Physician Executive Practice of Heidrick & Struggles, an executive search firm, sheds light on the emerging physician executive's role. The goal of the research was to identify success factors as a means of evaluating and developing effective industry leaders. Respondents were asked to look at specific skills in relation to nine categories: Communication, leadership, interpersonal skills, self-motivation/management, organizational knowledge, organizational strategy, administrative skills, and thinking. Communication, leadership, and self-motivation/management emerged, in that order, as the three most important success factors for physician executives. An individual's general competencies, work styles, and ability to lead others through organizational restructuring defines his or her appropriateness for managerial positions in the health care industry.     

Strangers meet: Laughter and nonverbal signs of interest in opposite-sex encounters

When strangers of the opposite-sex meet for the first time, both sexes are in a difficult situation. In this high risk situation, neither person knows the intention of the other, and consequently non-verbal signalling becomes the major channel for communication. Because of their higher biological risk, females should prefer less obvious tactics in order to communicate interest in a potential partner than males. The tactical task of signalling clearly, but at the same time subtly, is solved by the use of multifunctional or metacommunicative signals. In this study we propose that there is not one single meaning for any given signal. In laughing loudly we find a signal which consists of acoustical, mimical and postural information. In this way either laughter can send a this is play message or its meaning can be modified by other signals. Thus laughter, together with its accompanying body postures and movements, conveys messages that range from sexual solicitation to aversion, depending on which and how many different signals are present. Males seem to communicate interest for the female during laughter with only a few signals, such as body orientation and dominance signals. In contrast, females communicate interest via numerous signals which function as signals of bodily self-presentation and submission. In both sexes, a lack of interest is communicated through closed postures.Polly Wiessner, Jay Feierman and John Dittami have significantly helped with their ideas and have corrected what the author thought was the English language.
