Black-White Differentials in Adult Homicide Mortality in the United States

Objective . This article examines individual level black-white differences in adult homicide mortality. Homicide is a major social problem and a central cause of preventable death in the United States. A homicide not only claims one life prematurely but can also devastate a family, friends, and a neighboring community. Methods . We link eight consecutive years of the National Health Interview Survey (1987–94) to the Multiple Cause of Death file through the National Death Index (1987–97), and use Cox proportional hazard models to examine the role of social factors in black-white homicide mortality in the United States. Results . We find that individual level sociodemographic characteristics—age, sex, marital status, education, employment status, and geographic factors—explain almost 35 percent of the racial differences in homicide mortality. Conclusions . These results demonstrate the contributions that National Center for Health Statistics data can make to criminological literature and reveal the mechanisms through which blacks experience higher homicide mortality than whites. Such illumination may lead to a reduction in the fourth leading preventable cause of death in the United States.     

Expenditure Differences of University Degree Holders Across Occupational Sectors in Malaysia

This study was motivated by the key role university degree holders play in Malaysia's vision for the future and by concerns expressed about the drift of university degree holders from one sector to another. A questionnaire was mailed to a sample of 400 Malaysian families that had at least one member who held a university degree. The objective was to elicit details of the household economic situation of respondents, with special reference to the differences in expenditure patterns between families whose degree holder worked in higher education, government, or the private sector.Results of tobit analysis of expenditures show that there are some differences between the sectors regarding expenditure patterns, but the differences are not as great as expected. Nevertheless, university-educated persons in the private sector seem to have somewhat different expenditure patterns than their counterparts in other sectors.     

The impact of risk sharing on efficient decision

A group of risk-averse members must choose among monetary risks and payoff-sharing rules. Departure from the status quo requires unanimous consent. Such groups drill for oil, bail out nations, and make hostile takeover bids. Assume agreement on probabilities. As is well known, if all members have identically shaped HARA utility functions, efficient group act-choices follow another such function independently of payoff sharing. We show that all other groups inevitably have complex efficient behavior, accepting gambles among individually unacceptable lotteries in almost every status quo position. We also develop proper risk aversion for groups, and treat disagreement on probabilities.Support of the Associates of the Harvard Business School (Pratt) and the Business and Government and Energy and Environmental Policy Centers (Zeckhauser) is gratefully acknowledged. We received helpful comments from Scott Johnson, Mark Machina, and a referee. Jay Patel provided assistance beyond the call of collegiality.     

Young Carers: challenging the facts and politics of research into children and caring

This paper critically reviews existing research on young carers. I argue that our knowledge of what young carers do and how they differ from other children, is extremely limited. Without this information, practice recommendations will be based on guesswork and prejudice. I argue that the existing literature pays lip service to the support, or lack of it, that disabled people need to empower them as parents. In this context, I also review research into the relationship between disability and parenting. Research has tended to involve the search for the negative impact of an adult's disability on a child's growth, intelligence and adjustment. This has therefore told us little about how parental disability affects the domestic and caring tasks of children. There is a conceptual hole in the middle of our existing awareness about caring and childhood, with which future research must attempt to grapple.     

Seat belt laws: why we should keep them

In the June 2007 issue of Significance , John Adams argued for the repeal of seat belt laws. They have never been demonstrated to save lives, he said; and they increase the number of pedestrians and cyclists killed on the roads. Richard Allsop, Oliver Carsten, Andrew Evans and Robert Gifford argue that Parliament should keep the seat belt laws on the statute book and that we should all keep wearing belts whenever we travel in a car, van or coach—and they contest John's statistics.     

Bayesian point null hypothesis testing via the posterior likelihood ratio

This paper gives an exposition of the use of the posterior likelihood ratio for testing point null hypotheses in a fully Bayesian framework. Connections between the frequentist P-value and the posterior distribution of the likelihood ratio are used to interpret and calibrate P-values in a Bayesian context, and examples are given to show the use of simple posterior simulation methods to provide Bayesian tests of common hypotheses.     

A cross-national study of a method for researching non-profit organisational effectiveness

Are there criteria that define non-profit organisation effectiveness? If the criteria can be identified, is it possible to use them in a comparative study to assess whether and in what way the use of the criteria may vary between nations? This study addresses both questions. The study uses the factorial survey method and is based on the social constructionist conception that effectiveness is created as an ongoing and sometimes contested outcome of a social judgement process. We illustrate the method with samples from the US and UK and compare the results. The results establish the value of the factorial survey method. Analyses show that both US and UK respondents use percentage expenditures on fund-raising, advocacy emphasis, change in financial surplus and unit cost of services as effectiveness criteria. There is evidence that voluntarism is a more important criterion in the US and that advocacy is more important in the UK.     

Pathological gambling: A review of the literature (prepared for the American Psychiatric Association task force on DSM-IV committee on disorders of impulse control not elsewhere classified)

This is a review of the literature on pathological gambling prepared for the work group on disorders of impulse control, not elsewhere classified of the American Psychiatric Association. It introduces the new DSM-IV criteria as well as outlines the phases of the career of the pathological gambler. Research discussed includes that on pathological gambling and psychiatric disorders, substance abuse, family issues, children, finances, and crime. Psychoanalytic, personality, behavioral, sociological, psychologically based addiction theories, and physiological research are also summarized. Finally, treatment outcome studies are outlined.This article is dedicated to the memory of Robert L. Custer, MD whose inspiration and encouragement stimulated much of the research discussed herein.
