Risk aversion over finite domains

We investigate risk attitudes when the underlying domain of payoffs is finite and the payoffs are, in general, not numerical. In such cases, the traditional notions of absolute risk attitudes, that are designed for convex domains of numerical payoffs, are not applicable. We introduce comparative notions of weak and strong risk attitudes that remain applicable. We examine how they are characterized within the rank-dependent utility model, thus including expected utility as a special case. In particular, we characterize strong comparative risk aversion under rank-dependent utility. This is our main result. From this and other findings, we draw two novel conclusions. First, under expected utility, weak and strong comparative risk aversion are characterized by the same condition over finite domains. By contrast, such is not the case under non-expected utility. Second, under expected utility, weak (respectively: strong) comparative risk aversion is characterized by the same condition when the utility functions have finite range and when they have convex range (alternatively, when the payoffs are numerical and their domain is finite or convex, respectively). By contrast, such is not the case under non-expected utility. Thus, considering comparative risk aversion over finite domains leads to a better understanding of the divide between expected and non-expected utility, more generally, the structural properties of the main models of decision-making under risk.

     

Development and Application of a Probabilistic Risk–Benefit Assessment Model for Infant Feeding Integrating Microbiological,Nutritional, and Chemical Components

A probabilistic and interdisciplinary risk–benefit assessment (RBA) model integrating microbiological, nutritional, and chemical components was developed for infant milk, with the objective of predicting the health impact of different scenarios of consumption. Infant feeding is a particular concern of interest in RBA as breast milk and powder infant formula have both been associated with risks and benefits related to chemicals, bacteria, and nutrients, hence the model considers these three facets. Cronobacter sakazakii, dioxin‐like polychlorinated biphenyls (dl‐PCB), and docosahexaenoic acid (DHA) were three risk/benefit factors selected as key issues in microbiology, chemistry, and nutrition, respectively. The present model was probabilistic with variability and uncertainty separated using a second‐order Monte Carlo simulation process. In this study, advantages and limitations of undertaking probabilistic and interdisciplinary RBA are discussed. In particular, the probabilistic technique was found to be powerful in dealing with missing data and to translate assumptions into quantitative inputs while taking uncertainty into account. In addition, separation of variability and uncertainty strengthened the interpretation of the model outputs by enabling better consideration and distinction of natural heterogeneity from lack of knowledge. Interdisciplinary RBA is necessary to give more structured conclusions and avoid contradictory messages to policymakers and also to consumers, leading to more decisive food recommendations. This assessment provides a conceptual development of the RBA methodology and is a robust basis on which to build upon.     

Body-States,Body Image and Dissociation: When Not-Me is ‘Not Body’

The relationship between dissociation, eating disorders and disordered eating is key as it relates to dissociative disruptions to body image. It undermines normal integration of appearance-relevant information and cuts off access to subjective experience and feeling states necessary to form an internal representation of one’s self and body. This vulnerability contributes to body image distortions and the uncritical internalization of society’s notion of the thin ideal—which is an unrealistic standard, that leads, in turn, to body dissatisfaction. Patients with eating disorders live under the assumption that if they feel their sensations and feelings these will overwhelm them ‘forever’. The fear of being consumed by these terrible feelings, leads them to believe that ‘not feeling’-or even not existing-is the only answer. Being able to tolerate one’s subjective, affective experience is part of being able to internally represent one’s states, including body-states and to develop a stable experience of body image.     

Using action methods to counter social isolation and shame among gay men

ABSTRACT

Despite legal and cultural amelioration of homophobia, shame and internalized homophobia persist with concomitant adverse health and mental health consequences. J. L. Moreno's system of psychodrama, sociometry, and group psychotherapy offers approaches that help counter shame and internalized homophobia and increase peer support among diverse groups of gay men. Sociometric tools help create safety, establish group cohesion, build interpersonal connections, and strengthen identification and a sense of universality. The technique of doubling increases empathy. Explorations conducted during brief enactments using psychodramatic techniques heighten appreciation for diversity in the community while promoting self-acceptance and increased self-efficacy. Group sharing guidelines help strengthen mutual identification and mitigate shame and social isolation.     

The Erickson Life Study: A Five-Year Examination of a Screening Tool in a Continuing Care Retirement Community

Continuing care retirement communities are an increasingly popular housing choice for older adults. The purpose of this study is to evaluate the validity of an entrance tool to predict transitions over a 5-year time period. A sample of 261 participants was recruited. A discriminant analysis revealed that baseline scores correctly classified the Year 5 status of 71.3% of the cases, with 69.6% of those who experienced a change in status classified correctly. The use of the tool potentially provides the staff an objective means for pinpointing the areas where services may be required for the residents’ well-being.     

Responsive Persistence Part I: Therapist Influence in Postmodern Practice

Feminist and social constructionist developments in family therapy highlighted the importance of attending to therapist–client power relations and incorporating clients' understandings and preferences as a part of therapy. Significantly, less attention has been given to how postmodern therapists do use their power and influence. This is an important topic because it is therapists who have the major responsibility for guiding the interaction with clients and persisting in this so that change is facilitated. Therapist persistence in various forms and across dimensions of therapy process is examined to expand understanding of therapist influence in postmodern and collaborative work. An analysis of responsive persistence in a session with Karl Tomm as the therapist is presented to illustrate this conceptual framing.     

Stuck in a Loop: Individual and System Barriers for Job Seekers With Disabilities

Research conducted within Temporary Assistance to Needy Families (Personal Responsibility and Work Opportunity Reconciliation Act of 1996) and Workforce Investment Act of 1998 systems indicates pervasive issues hindering program effectiveness for job seekers with disabilities. This population frequently experiences employment barriers beyond those of able‐bodied job seekers, including significantly lower self‐esteem. Service providers need and want information about disability but do not know how to obtain it. Program staff and job seekers with disabilities get stuck in a loop wherein each questions their ability and neither feels empowered to make meaningful changes to improve outcomes. Career counselors may need to expand their role to be more culturally relevant for these clients.     

An Experiment to Modify Self-Concept and School Performance

Abstract

The joint or combined effects of age level, sex differences, and social factors in fear of crime are systematically investigated using elaboration analysis with 1976 NORC data. Findings reveal that while the elderly are somewhat more likely to report fear of crime when compared with young and middle-aged groups, many more women express apprehension than men at each age level. Fear of being victimized is especially prevalent among those segments of the population that are the most isolated and vulnerable, notably elderly and middle-aged black women, unmarried older women living alone, elderly women in poor health, and women of all ages who had been burglarized.     

Introduction

In a time of segmented media markets, enormous potential audiences, and multiple means for audiovisual communication worldwide, it is important to define clearly the purpose of “public communication of science”; projects and initiatives and by what criteria they should be evaluated. Conveyed within a popular format, scientific information contains considerable potential for stimulating change, affecting personal decisions about diet and health, influencing political decisions, or shaping a community's perception of risk. Presence (or absence) of scientific information can empower (or isolate) citizens in a highly technological world, but access alone is insufficient when the amount of information from all sources increases rapidly. Current strategies for allocating resources and setting policy for public communication of science activities follow an outdated and potentially dangerous course because they emphasize volume over all other parameters. This article proposes a re‐examination of science communication policies, with the goal of improving the public's ability to evaluate the quality, validity, legitimacy, and relevance of all scientific information to which public audiences are daily exposed, regardless of its source.     

Barriers to girls' education in Mozambique at household and community levels: an exploratory study

Although education of children is universally accepted as a leading mechanism of poverty eradication and social development, many developing nations continue to struggle in achieving gender parity in primary and secondary education. While Mozambique has recently accelerated its efforts to reduce this gap, girls are still enrolled and attending school at a much lower rate than boys. The present study explored the barriers to children's – especially girls' – education in central Mozambique, based on information on 738 children in two separate communities. Household, child, environmental, and social/cultural factors are examined in the context of global and regional data. The study found girls to be impacted more negatively by every correlating factor, including the lingering practice, in rural areas, of early marriage. Policy and research implications are discussed.
