Finite sensibility and utility functions

According to the concept of finite sensibility an individual utility function has to fulfill Ng's (1975) Convention 1. In this paper we show that relatively weak assumptions already guarantee the existence of a utility function with the desired property and we present a procedure for constructing such a utility function.     

A Screening,Brief Intervention,and Referral to Treatment Collaborative: Impact for Social Work Students

Screening brief intervention, and referral to treatment (SBIRT) is a clinical intervention empirically linked to reductions in substance usage. However, less is known on how to effectively train social work students on SBIRT. This study examines the impact of a SBIRT training administered to BSW and MSW students (N=228) at the University of Oklahoma. Based on exposure to the training, our evaluation measured changes on students’ objective knowledge of how to perform SBIRT and in attitudes toward practicing with substance users. Results indicated exposure to the training was associated with robust gains across variables and across classes. Such results suggest that the proffered SBIRT training is an effective means to educate social work students on substance abuse practice.     

Physical and psychological partner aggression across a decade: a growth curve analysis

The course of physical and psychological partner aggression was investigated over a decade in 203 wives from Suffolk County, New York. Wives reported on their own and on their partners' aggression at one month before marriage and 6, 18, 30, and 120 months after marriage. This follow-up is the longest period over which partner aggression has been examined. Prevalence rates of wife's report of wife- and husband-perpetrated physical aggression were 48% and 35% at premarriage, and 13% and 10% ten years later. Using HLM, husband- and wife-perpetrated physical aggression were found to decrease on average approximately one act of aggression per month, regardless of severity and even when controlling for changes in marital satisfaction. There was no significant pattern of change in psychological aggression. These findings are consistent with cross-sectional analyses, and suggest that physical partner aggression decreases in community samples of couples.     

Identifying key influencers of Chinese PR practitioners’ strategic conflict management practice: A survey on contingent variables in Chinese context

As the first quantitative test of contingency theory in China using an online survey, this study examined the influence of each of the over 80 individual contingent variables as perceived by Chinese public relations practitioners. Individual characteristics as related to conflict management as well as political–social factors were identified as the most influential variables. By forming influential contingent factors and exploring the dimensionality of these factors using factor analysis, the results of this study suggested structural stability of the contingency matrix. Further, the effects of gender and types of organizations were tested on how Chinese practitioners perceive these influences in their public relations practice. The findings provide insights for both practitioners and researchers on how to strategically identify and combine the most influential factors in effective and ethical conflict management in China.     

Posttraumatic Stress and Depression in the Nonoffending Caregivers of Sexually Abused Children: Associations With Parenting Practices

Caregiver mental health is a known correlate of parenting practices, and recent research indicated that parental depression following childhood sexual abuse disclosure is associated with concurrent parenting difficulties. The present study extended this line of research by investigating posttraumatic stress symptoms and depression in a sample of caregivers (N = 96) of children who experienced sexual abuse recruited from a child advocacy center as well as parenting practices reported by both caregivers and their children (mean age = 10.79 years, SD = 3.29; 79% female). Twenty-four percent of caregivers met criteria for presumptive clinical depression, clinically significant posttraumatic stress, or both. Results indicated elevated caregiver-reported inconsistent parenting in the context of clinically significant distress across symptom groups; children reported particularly elevated inconsistent parenting for caregivers with posttraumatic stress only. Caregiver depression was associated with low self-reported positive parenting and caregiver involvement in addition to self-reported inconsistencies. Directions for future research are offered to further elucidate the relationships between caregiver mental health and parenting practices following childhood sexual abuse.     

HIV diffusion patterns and mobility: Gender differences among drug users

Researchers have recently expanded the scope of study of transmission patterns of AIDS to incorporate spatial and geographical questions. United States diffusion patterns of this disease appear to indicate that it may emanate from urban area epicenters to areas of low and moderate prevalence. The travel patterns of injecting drug users (IDUs) and the extent to which they engage in high risk drug and sexual activities was examined as an explanation of diffusion of the HIV virus from one community to another. The study population of 49,621 was comprised of subjects recruited from approximately 60 sites nationwide from 1988–1991. While the data are limited in some ways, they partially support a diffusion explanation of HIV transmission for males and females. The analysis demonstrates that low prevalence cities were significantly more likely to have been the destinations of both men and women who engaged in high risk drug and sexual activities. In addition, HIV seropositive drug users who engaged in high risk drug and sexual behaviors in destination cities were more likely than seronegatives to travel to high or low seroprevalence areas than to moderate prevalence areas. The findings suggest a need for effective HIV prevention educational messages about the risks of traveling and participating in high risk activities.     

Hungary in transition: a computable general equilibrium model comparison with Austria

We approach the problem of Hungary's transformation from a partially centrally planned to a market-oriented economy with a cross-country comparison using two computable general equilibrium (CGE) models of Hungary, 1977 and 1986, and one of Austria, 1976. These three models represent a continuum of small open economies and allow a “quasidynamic” analysis using static CGE models. We examine two types of transformation issues: external (trade liberalization, import price reductions, and redirection of foreign trade; “Dutch Disease reversal”) and internal (decreases in subsidy levels). Overall, it is clear that with Hungary's borrowing constraints, liberalization should not be pursued in isolation; a change in the tax structure is necessary at the same time. The results for Austria indicate that liberalization brings smaller welfare improvements accompanied by smaller increases in the current account and government deficits.     

On the Selection of Distributions for Stochastic Variables

One of the main steps in an uncertainty analysis is the selection of appropriate probability distribution functions for all stochastic variables. In this paper, criteria for such selections are reviewed, the most important among them being any a priori knowledge about the nature of a stochastic variable, and the Central Limit Theorem of probability theory applied to sums and products of stochastic variables. In applications of these criteria, it is shown that many of the popular selections, such as the uniform distribution for a poorly known variable, require far more knowledge than is actually available. However, the knowledge available is usually sufficient to make use of other, more appropriate distributions. Next, functions of stochastic variables and the selection of probability distributions for their arguments as well as the use of different methods of error propagation through these functions are discussed. From these evaluations, priorities can be assigned to determine which of the stochastic variables in a function need the most care in selecting the type of distribution and its parameters. Finally, a method is proposed to assist in the assignment of an appropriate distribution which is commensurate with the total information on a particular stochastic variable, and is based on the scientific method. Two examples are given to elucidate the method for cases of little or almost no information.
