Demographic changes as a problem for social security systems

The relationship between demographic changes and the social security system is explored. The focus is on the current situation in the Federal Republic of Germany, but consideration is also given to comparable developments in other developed countries. Emphasis is placed on how changes in the age distribution of modern populations affect the relative proportion of the productive and the dependent populations.     

Looking Too Old? How an Older Age Appearance Reduces Chances of Being Hired

Building on theories of impression formation based on faces, this research investigates the impact of job candidates’ facial age appearance on hiring as well as the underlying mechanism. In an experiment, participants decided whether to hire a fictitious candidate aged 50 years, 30 years or without age information. The candidate's age was signalled either via chronological information (varied by date of birth) or via facial age appearance (varied by a photograph on the résumé). Findings showed that candidates with older‐appearing faces – but not chronologically older candidates – triggered impressions of low health and fitness, compared to younger‐appearing candidates. These impressions reduced perceptions of person–job fit, which lowered hiring probabilities for older‐appearing candidates. These findings provide the first evidence that trait impressions from faces are a determinant of age discrimination in personnel selection. They call for an extension of current models of age discrimination by integrating the effects of face‐based trait impressions, particularly with respect to health and fitness.

Rules Trump Desires in Preschoolers’ Predictions of Group Behavior

The objective of this article is to investigate the way children weigh conventional rules against desires when considering how a group will behave. To do so, two experiments involving a prediction task in which desires were pitted against conventional rules were presented to three‐ to five‐year‐old children. In Experiment 1, four scenarios were established as classroom scenes in which either one protagonist or three protagonists had a desire that went against an explicit conventional rule. In the individual control condition, the choices linked to the rules were at chance whereas, in the group condition, the participants predicted that all the protagonists would end up following the rule. Given that both conditions in Experiment 1 implied four rule followers in the design, Experiment 2 staged not three but seven potential rule transgressors to see whether the desire of the majority might undermine the rule. Results showed no majority effect: participants expected protagonists to act counter to their desire and to follow the rule. Such results suggest that children as young as three‐year‐old favor rules over desires when they have to predict the behavior of a group, whether it be the majority or not. Possible implications of these intriguing findings are discussed.     

Analysis of a longitudinal ordinal response clinical trial using dynamic models

Summary.  In many areas of pharmaceutical research, there has been increasing use of categorical data and more specifically ordinal responses. In many cases, complex models are required to account for different types of dependences among the responses. The clinical trial that is considered here involved patients who were required to remain in a particular state to enable the doctors to examine their heart. The aim of this trial was to study the relationship between the dose of the drug administered and the time that was spent by the patient in the state permitting examination. The patient's state was measured every second by a continuous Doppler signal which was categorized by the doctors into one of four ordered categories. Hence, the response consisted of repeated ordinal series. These series were of different lengths because the drug effect wore off faster (or slower) on certain patients depending on the drug dose administered and the infusion rate, and therefore the length of drug administration. A general method for generating new ordinal distributions is presented which is sufficiently flexible to handle unbalanced ordinal repeated measurements. It consists of obtaining a cumulative mixture distribution from a Laplace transform and introducing into it the integrated intensity of a binary logistic, continuation ratio or proportional odds model. Then, a multivariate distribution is constructed by a procedure that is similar to the updating process of the Kalman filter. Several types of history dependences are proposed.     

Synthesizing the interests of consumers, citizens, and administrators in gathering client feedback

In a large metropolitan county's mental health system program evaluators involved consumer representatives, advisory board, and administrators in a client feedback study. The evaluators presented the groups with a “menu” of possible questions, and members of each group selected items where it would be particularly useful to know the opinions of clients. The groups did not agree about the kinds of questions that were desirable. The evaluators created a survey instrument that included high-priority items from each group. The survey was completed by 205 outpatients in three sites. Clients expressed a nearunanimous opinion about some questions, while on other issues there was no client consensus. In human service systems where decision making is shared by people with potentially conflicting interests, the authors recommend polling groups of decision-makers and then uniting their interests in a study of client feedback.     

Dysfunctional Transactions and Therapeutic Functions: An Evolutive Model

The present study is a result of an interdisciplinary team's work, where a physicist, a family therapist and a developmental psychologist try to share their knowledge and epistemologies. In this kind of conflictual companionship, models of one discipline are tentatively applied to another. This doesn't imply that the different disciplines are isomorphic, but it provides for unusual frames of reference: questions, possibly essential ones, are reformulated in a new language, or in a perspective which was not accessible within the conceptual framework developed for one particular discipline. Our experience is that this kind of effort, in itself a provocative learning experience, is also conducive to original tentative answers in all disciplines involved. Be they of theoretical or experimental nature, it is then up to the specialists of these disciplines to validate the evolved propositions in terms of their own categories.
