Short-term treatment with the adolescent client

Short-term treatment is proposed as the treatment of choice for adolescents because it is consistent with the developmental needs and goals of that age group. Several case illustrations have been provided to show the value and benefit of such an approach for the adolescent client as well as for the therapist.     

Can ranking techniques elicit robust values?

This paper reports two experiments which examine the use of ranking methods to elicit ‘certainty equivalent’ values. It investigates whether such methods are able to eliminate the disparities between choice and value which constitute the ‘preference reversal phenomenon’ and which thereby pose serious problems for both theory and policy application. The results show that ranking methods are vulnerable to distorting effects of their own, but that when such effects are controlled for, the preference reversal phenomenon, previously so strong and striking, is very considerably attenuated.

On the Owen Set of Transportation Solutions

This paper presents an axiomatic characterization of the Owen set of transportation games. In the characterization we use six properties including consistency (CONS2) and splitting and merging (SM) which are firstly proposed and defined for this setup in the present paper.     

Evidence of a new violation of the independence axiom

During the past 40 years there has been an accumulation of experimental evidence suggesting that most of the axioms of expected utility theory are liable to be systematically violated by substantial numbers of individuals. Much of this evidence has focused on failures of the independence axiom and has stimulated a number of alternative models that try to explain that evidence in various ways. This article presents a fresh experiment that looks at a different kind of violation—one that does not appear to be easily accommodated by several of the more prominent alternative models as they are currently formulated.The experimental work reported in this article was funded by Economic and Social Research Council Award No. B 00 23 2163.     

Risk reduction or risk compensation? The case of mandatory safety-belt use laws

The technological approach to risk regulation seeks to lessen the incidence of mortality and morbidity by modifying environmental conditions. Insofar as risk-taking behavior is purposive, social scientists have predicted that technological progress may be negated by various forms of risk compensation. The validity of this hypothesis is tested in the transportation sector with data from the U.S. on the effects of new mandatory safety-belt-use laws. A fixed-effects model of traffic fatality counts is estimated using pooled data from 50 states during the 1975–1987 period. Results suggest that such laws have reduced mortality among car occupants to a degree that is compatible with the predictions of technologists. However, there is weak evidence of increased mortality among some nonoccupants, a pattern predicted by risk-compensation theorists. The lifesaving effects of belt-use laws are largest in states that permit primary police enforcement and appear to be somewhat larger for front-seat occupants age 21 and under. Although offsetting behavior appears to be small relative to lifesaving effects, it may take several more years for any compensatory behavior to achieve a new equilibrium.This research was supported in part by a grant from the Centers for Disease Control to the New England Injury Prevention Research Center.     

Service workers' responses to abuse of the elderly

The social service providers and physicians who encounter elder abuse have several potential avenues of intervention open to them in helping the elderly. Practice and training issues are discussed that are relevant for improving interventions and referrals in cases of family abuse of the elderly.
