THE COURTS AS A SOURCE OF REGULATORY REVITALIZATION: EXTERNAL AGENDA SETTING AND EQUAL EDUCATION PROGRAMS

The authors examine the relationship between the courts and HEW's Office for Civil Rights (OCR), to illustrate the effects of legal efforts to generate more vigorous agency enforcement. Opponents of racial and sex discrimination in public schools won a series of suits against OCR after it had ceased to effectively implement anti-discrimination legislation. As a result of court decisions, OCR has had its discretion over how it will carry out its legislative responsibilities curtailed.     

Treatment-Related Reductions in Disability Are Associated with Reductions in Perceived Injustice Following Treatment of Whiplash Injury

Emerging evidence suggests that perceived injustice is a risk factor for poor recovery outcomes in individuals with whiplash injuries. The present study examined the relative contributions of treatment-related reductions in pain severity, depressive symptoms, and disability in the prediction of reductions in perceived injustice in individuals with whiplash injury. The study sample consisted of 71 individuals (43 women and 28 men) who sustained whiplash injuries in motor vehicle accidents and who were enrolled in a treatment program designed to promote functional recovery following whiplash injury. For the purposes of this study, only individuals who scored above the risk threshold on a measure of perceived injustice were included in the study sample. Participants completed measures of pain severity, disability, depressive symptomatology, and perceived injustice prior to treatment and after treatment. Change scores were computed for study variables. The results revealed that reductions in pain severity and disability were correlated with reductions in perceived injustice. Regression analyses revealed that only reductions in disability contributed significant unique variance to the prediction of reductions in perceived injustice. Clinical and theoretical implications of the present findings are discussed.     

Is It a Fight or Are They Just Drunk? Attributions about Drunken Behaviour in a Hypothetical Male‐to‐Male Aggression Scenario1

Objective. This paper examines the excuse‐value of alcohol in a hypothetical provoked male‐to‐male violence scenario. There are two main questions. Does intoxication result in decreased blame? Does intoxication lessen the propensity to call the police?

Methods. 1004 random digit dialing (RDD) quantitative telephone surveys were completed with Swedes aged 16–25. The response rate was 73.8%. Besides the aggressor's intoxication, severity of the outcome, the victim's intoxication and the respondent's hypothetical relationship to the aggressor or to the victim were also randomly manipulated. Whether the police should be called and the attribution of blame to the aggressor have been analysed using ANOVA in SAS.

Results. Analyses were stratified by sex. For male respondents, the aggressor's intoxication interacted (four‐way) with all the manipulated variables in predicting the attribution of blame. In the more severe act, intoxication tended to reduce blame; the least amount of blame was assigned when both the aggressor and the victim were intoxicated. For female respondents, the aggressor's intoxication was involved in a three‐way interaction. For them also, intoxication decreases the blame for the severe acts but not for the less severe acts. The aggressor's intoxication had very little effect on whether the police should be called or not.

Discussion. Intoxication provides some excuse from blame but only for certain acts and under certain circumstances. It also changes the way people perceive acts of violence.     

The psychological effects of solitary confinement on prisoners in supermax units: reviewing what we know and recommending what should change

This article examines the psychological consequences of short- and long-term solitary confinement for prisoners in the United States subjected to administrative or disciplinary segregation. Particular attention is paid to the use of secure housing units, alternatively known as control units or supermax units. These correctional entities allow for the isolation of convicts under conditions that offer little sensory stimulation and minimal opportunities for interaction with other people. The circumstances typically found in these units and the heightened potential for the abuse of prisoners are described. The connections between internment and mental illness-as well as isolation and race, gender, and class-are explored. A set of recommendations for the reform of secure housing is presented.     

Reconsidering pocketbook voting: An experimental approach

Despite its deep theoretical roots, the idea that voters reward or punish incumbents in national elections for trends in their personal financial circumstances has not fared well when subjected to empirical test. This paper poses an experimental test of the leading explanations for the surprisingly weak showing of pocketbook influences on vote choice. According to certain of these explanations, the answer lies in distinguishing between sociotropic and self-interested economic voting, or between retrospective and prospective economic voting, or between perceptions of economic trends in general and perceptions of the electorally relevant component of these trends. However, expectations based on these explanations are generally not borne out in the laboratory setting. Consistent with the observed pattern of effects, however, is the idea that pocketbook voting displays little independent impact because economic perceptions and attributions are epiphenomena—strongly biased by the voter's preexisting political commitments.     

Suffocation using plastic bags: a retrospective study of suicides in Ontario, Canada

One hundred and ten cases of suicidal suffocation using a plastic bag were identified in the files of the Office of the Chief Coroner of Ontario, Canada, between 1993 and 1997. The records were reviewed to determine the demographic characteristics of this group compared with all cases of suicide in Ontario, the scene information, autopsy findings and toxicology results. Most suicides occurred in people over 60 years of age, with older women making up a considerable proportion of cases as compared with other methods of suicide. In 40% of cases the deceased was suffering from a serious illness. Autopsy findings were usually minimal, with facial, conjunctival and visceral petechiae present in a minority of cases. One or more drugs were detected in the blood in 92.6% of cases where toxicologic testing was performed. Benzodiazepines, diphenhydramine and antidepressants were the most common drugs found, with diphenhydramine the most common drug present at an elevated concentration. Information at the scene from "right to die" societies was uncommon. One quarter of decedents took additional measures, besides the use of drugs or alcohol, to ensure the rapidity, certainty or comfort of their death. This study further elucidates the characteristics of this uncommon method of suicide. It emphasizes additional scene findings, such as the presence of dust masks, physical restraints and modification of the plastic bag that may be of use to death investigators in determining the correct manner of death.
