Prisoners of Conscience

Amnesty International is a human rights organisation that operates right around the world. This article describes its objectives and methods, and discusses some of the factors which have contributed to its successful growth over the past 27 years. It also looks at the relationships between the organisation, the offending authorities and the victims of oppression and their families.     

On adaptive estimation

Point estimates that are weighted averages of other estimates are considered. They are adaptive because the weights are also functions of the sample observations.In particular, the weights are functions of new measures of peakedness and skewness. Five adaptive estimators are compared (in a Monte Carlo study using the swindle) to some of the usual estimators, including those robust ones of Huber and Tukey. In addition, the swindle constant is considered in some detail. All of the adaptive estimators do extremely well with an adaptive biweight statistic being the best one in this study. Suggestions are made about future directions in this area.     

On borrowing spread from auxiliary samples in the one-sample problem

This study is concerned with the one-sample problem and the notion of how to use (borrow) information contained in one or more auxiliary samples. A variety of t-statistics and borrowning schemes is used to shed light on this area. It is found that if the data do not come from a Gaussian distribution then the traditional method of borrowing by root-mean-square need not be the best thing to do. (In fact, for Student's t-statistic it is never the best thing to do.) it is also shown that if one borrows wisely, substantial gains can be made for small sample sizes. Finally, if one places a premium on computational ease, then there are simple procedures that can do reasonably well under a variety of circumstances.     

23rd Family Therapy Conference; A Student's Perspective

Greetings! I am a family worker in regional Victoria, and a post grad student in Family Centred Practice. Being relatively new to the field I was pleasantly surprised to be asked to review the 23rd Family Therapy Conference, Hobart 2002. This was my first Family Therapy conference, and these are my impressions.     

An examination of ecological predictors of health literacy in black college students

Objective: Health literacy is a determinant of health, but disparities in health literacy persist. This study examined the influence of ecological factors on college students’ health literacy. Participants: During January 2016 a nonrandom sample of black undergraduate students (n = 298) aged 18–24 were recruited from enrollment lists at two urban universities in the Southeastern United States. Methods: Information on health literacy as well as numerous intrapersonal, social, and cultural-environment factors was obtained using an electronic questionnaire and then statistically modeled. Results: Ecological factors accounted for 28.7% of the variance in health literacy. In particular, reappraisal (B = 0.323, p < .001), suppression (B = ?0.289, p < .001), campus health education (B = 0.192, p < .05), campus tobacco culture (B = ?0.174, p < .05), and perceived norms (B = ?0.153, p < .05) directly predicted health literacy. Conclusions: Although intrapersonal factors influence health literacy, the sociocultural environment of college can also foster or hinder college students’ health literacy.     

Measures of Societal Risk and Their Potential Use in Civil Aviation

This article seeks to clarify the conceptual foundations of measures of societal risk, to investigate how such measures may be used validly in commonly encountered policy contexts, and to explore the application of these measures in the field of civil aviation. The article begins by examining standard measures of societal and individual risk (SR and IR), with attention given to ethical as well as analytical considerations. A comprehensive technical analysis of SR is provided, encompassing scalar risk measures, barrier functions, and a utility‐based formulation, and clarifications are offered with respect to the treatment of SR in recent publications. The policy context for SR measures is shown to be critically important, and an extension to a hierarchical setting is developed. The prospects for applying SR to civil aviation are then considered, and some technical and conceptual issues are identified. SR appears to be a useful analytical tool in this context, provided that careful attention is given to these issues.     

Evaluation of Support Groups for Child Abuse Prevention: Outcomes of Four State Evaluations

ABSTRACT

Parent support groups have grown in popularity as a strategy for preventing child maltreatment, but there have been few evaluations of these groups. The purpose of this paper is twofold. One goal is to identify some of the major challenges in the evaluation of parent support groups and to provide strategies for minimizing these potential difficulties. The second goal is to illustrate successful evaluations of parent support groups (i.e., the Circle of Parents® program) in four states. Three of these states used a retrospective pretest method. Outcomes indicated positive performance across all domains of functioning, as measured by a self-report questionnaire. Strengths and limitations of the evaluations are discussed, and recommendations for future evaluations are provided.
