An axiomatic system for multidimensional preferences

An axiomatic system TP is developed which allows the amalgamation of linear preferences (preferences in respect to different criteria) according to the weights of those criteria. Section 1 deals with linear preferences. In Section 2 an axiomatic system for the ordering of classes of criteria is formulated. Section 3 explains the development of system TP. Two TP-systems are distinguished, based on two different linear preference systems. The preference relation of TP is shown to be nontransitive, while the linear preference relation is transitive. In 3.7 an alternative-system TP′ is given. Section 3.8 deals with formulas concerning the disjunction of alternatives, which are not valid in TP, even though they are valid in a linear preference system. In Section 4 types of preference relations and types of alternatives are distinguished to get the opportunity to express preferences between preferences.     

The Social Work Assessment Tool (SWAT)

This paper reports on the last of three National Hospice and Palliative Care Organization initiatives to move hospice and palliative care social workers into the patient/family outcomes arena: the development of the Social Work Assessment Tool. The experience of a team of practitioners and researchers is described, including results of two pilot studies and subsequent SWAT revisions. The major focus is on the current model performance improvement project, in which 19 social workers from 14 hospice and palliative care programs used the SWAT with 101 patients and 81 primary caregivers for a median of 44 days. Quantitative analysis indicated significant improvement in SWAT scores for patients from the first to the second social work visit (t = -2.60, df = 47, p .01). Qualitative interviewing of the social workers indicated some lack of readiness in the field to conduct quantitative outcomes measurement. Additional measures are needed in addition to the SWAT, including qualitative measures, and measures of mezzo and macro practice. Participants indicated that the SWAT was appropriate for use with economically and culturally diverse clients.     

Is Psychological Well-Being Linked to the Consumption of Fruit and Vegetables?

Little is known about the influence of people’s diet on their psychological well-being. This study provides evidence of a link between the consumption of fruit and vegetables and high well-being. In cross-sectional data, happiness and mental health rise in an approximately dose–response way with the number of daily portions of fruit and vegetables. Well-being peaks at approximately 7 portions per day. We document this relationship in three data sets, covering approximately 80,000 randomly selected British individuals, and for seven measures of well-being (life satisfaction, WEMWBS mental well-being, GHQ mental disorders, self-reported health, happiness, nervousness, and feeling low). The pattern is robust to adjustment for a large number of other demographic, social and economic variables. Reverse causality and problems of confounding remain possible. We discuss the strengths and weaknesses of our analysis, how government policy-makers might wish to react to it, and what kinds of further research—especially randomized trials—would be valuable.     

Power,Sex, and Rape Myth Acceptance: Testing Two Models of Rape Proclivity

Power and sex are thought to be important factors associated with sexual aggression. The goal of this study was to offer a dual-process model to determine how both an implicit power–sex association and explicit power–sex beliefs contribute to rape myth acceptance and rape proclivity. In Study 1, an explicit measure of power–sex beliefs was developed using a participant sample of 131 college students (54% female; age: M = 20.2 years, SD = 3.5 years). In Study 2, 108 male college students (age: M = 19.1 years, SD = 1.3 years) completed a power–sex implicit association test and three explicit measures assessing power–sex beliefs, rape myth acceptance, and rape proclivity. Two models of rape proclivity were compared. The best-fitting model showed that rape myth acceptance mediated the relationships between rape proclivity and an implicit power–sex association, as well as explicit power–sex beliefs.     

An analysis of some factors associated with success and failure in foster home placements

There has been little information available in the social work and sociological literature related to remarriage in Australia. In 1968, there were 106,345 marriages of which 14,116 unions involved at least one partner who had been married previously.¹ Thus, 13.3 per cent of all the marriages can be considered second marriages for one partner at least. Table 1 summarizes the marital status of bridegrooms and brides at the time of their marriage in 1968.     

METHODS FOR QUANTIFYING SUBJECTIVE PROBABILITIES AND MULTI-ATTRIBUTE UTILITIES*†

In many situations where normative decision-aiding techniques could be usefully applied, historical data are inadequate for estimating the required outcome probabilities, and economic methodologies are inadequate for estimating the aggregate utility derived from the several outcome attributes. In such cases it is often useful to obtain the required estimates in the form of expert judgments, i.e. to obtain subjective probabilities and multi-attribute utilities. Similarly, in many situations where behavioral decision processes are to be studied, it is necessary to scale the expectations and perceived values of the decision makers. This article describes the methods for eliciting subjective probabilities and multi-attribute utilities whose usefulness has been empirically studied and reported in the research literature. It also contains summary guidelines concerning the elicitation and use of such judgments.     

Lenski Effects on Sex Stratification Theory

This paper tries to explain why the Lenski (1970) theory of stratification based on ecology and subsistence technology had relatively little effect on theories of sex inequality. In cultural anthropology, generalization was held to be impossible. Feminist explanation in sociology was social-psychological. Moreover, by the 1980s, the bias against biology in feminist theory came to include all of science. Exceptions to these trends include the work of Blumberg, Chafetz, Collins, Coltrane, and Turner. Whether feminist sociologists will follow their lead remains to be seen.     

Smoking and Membership in a Fraternity or Sorority: A Systematic Review of the Literature

Abstract

Objective: Fraternity and sorority members have higher rates of smoking than other college students. This systematic review examines studies that included fraternity/sorority membership in their investigation of smoking behaviors. Participants/Methods: Studies identified in MEDLINE, PsychInfo, JSTOR, CINAHL, ERIC, and Google Scholar published between 2003 and 2013 were included if they included fraternity and/or sorority membership, were written in English, published in a peer-reviewed journal, and had smoking as an outcome variable. Nineteen studies were identified for the review. Results: Fraternity/sorority members were more likely to be nondaily smokers. Members who lived in the fraternity/sorority house had higher rates of smoking than members who lived elsewhere. Fraternity/sorority member smoking was associated with alcohol and other substance use. The influence of no-smoking policies on fraternity/sorority member smoking was also examined. Conclusions: Fraternity/sorority membership was associated with higher rates of smoking, but this association was influenced by other substance use and environmental factors.

A comparison of subgroup identification methods in clinical drug development: Simulation study and regulatory considerations

With advancement of technologies such as genomic sequencing, predictive biomarkers have become a useful tool for the development of personalized medicine. Predictive biomarkers can be used to select subsets of patients, which are most likely to benefit from a treatment. A number of approaches for subgroup identification were proposed over the last years. Although overviews of subgroup identification methods are available, systematic comparisons of their performance in simulation studies are rare. Interaction trees (IT), model‐based recursive partitioning, subgroup identification based on differential effect, simultaneous threshold interaction modeling algorithm (STIMA), and adaptive refinement by directed peeling were proposed for subgroup identification. We compared these methods in a simulation study using a structured approach. In order to identify a target population for subsequent trials, a selection of the identified subgroups is needed. Therefore, we propose a subgroup criterion leading to a target subgroup consisting of the identified subgroups with an estimated treatment difference no less than a pre‐specified threshold. In our simulation study, we evaluated these methods by considering measures for binary classification, like sensitivity and specificity. In settings with large effects or huge sample sizes, most methods perform well. For more realistic settings in drug development involving data from a single trial only, however, none of the methods seems suitable for selecting a target population. Using the subgroup criterion as alternative to the proposed pruning procedures, STIMA and IT can improve their performance in some settings. The methods and the subgroup criterion are illustrated by an application in amyotrophic lateral sclerosis.
