Improving data utilization: the case-wise alternative

Both research and practical experience suggest that alternative forms of data analysis and presentation may affect their use in the policy arena. The variable-wise alternative produces estimates of population parameters through conventional statistical techniques. The case-wise alternative defines and identifies qualitatively distinct types of cases through techniques of numerical taxonomy. In the experiment reported here, variable-wise and case-wise presentations of Census data on poverty were used to compare the effects of the alternatives on policy makers in a priority-setting task. The results show that the case-wise alternative can improve utilization, assimilation, recall, and recognition of the data. Under the circumstances examined here, the case-wise alternative is a practical means of increasing the return on the public's investment in data resources to improve policy decisions.     

The effects of outlier presence,plaintiff population size,and aggregation of plaintiffs on simulated civil jury decisions

An experiment was performed to determine the effects of the size of the plaintiff population, the presence or absence of an outlier, defined as a plaintiff whose injuries were significantly more severe than other plaintiffs, and whether plaintiffs were tried individually or were aggregated in a group. Sixty-six person juries were assigned to one of eleven experimental conditions, listened to a 4-h toxic tort tria, and after deliberating, delivered verdicts on liability, and damage awards. The verdicts were increased significantly by the presence of an outlier and by an increase in the plaintiff population. While the punitive awards were higher in the outlier condition, there was also a tendency for juries to find the company not liable.The meaning of the above findings, as well as the fact that juries exhibited great variability in their verdicts was discussed. Evidence as to the decision-making process of the juries was also gathered and discussed.This research was supported by National Science Foundation Grant SES 860 9892 and by a University of Toledo College of Arts and Sciences Faculty Development Grant.

Recovery and identification of the victims of the Ehime Maru/USS Greeneville collision at sea

This paper describes the recovery and identification of crew members lost during a collision at sea. On 9 February 2001, south of Honolulu, Hawaii, the Japanese fishing training boat, Ehime Maru was struck by the USS Greeneville (SSN 772), a Los Angeles-class fast attack submarine. Witnesses estimate that the vessel sank within 5-10 min after the collision. Nine of the 35 crew members remained unaccounted for after rescue procedures were completed. The U.S. Navy attempted the unprecedented procedure of moving the boat from a depth of 610 m (2000 ft) into shallower waters so that the missing could be located and recovered. Eight of the nine crew members were recovered and identified by their dental records.     

Response Latency Methodology for Survey Research: Measurement and Modeling Strategies

In public opinion research, response latency is a measure ofattitude accessibility, which is the ease or swiftness withwhich an attitude comes to mind when a respondent is presentedwith a survey question. Attitude accessibility represents thestrength of the association in memory between an attitude objectand an evaluation of the object. Recent research shows thatattitude accessibility, as measured by response latency, castslight on a wide range of phenomena of public opinion and politicalbehavior. We discuss response latency methodology for surveyresearch and advocate the use of latent response latency timers(which are invisible both to respondents and interviewers) asa low cost, low-maintenance alternative to traditional methodsof measuring response latency in public opinion surveys. Weshow that with appropriate model specification latent responselatency timers may provide a suitable alternative to the morecomplicated and expensive interviewer-activated timers.     

Mental health correlates of the victim-perpetrator relationship among interpersonally victimized adolescents

This research examines mental health correlates of different victim-perpetrator relationships among adolescent victims of interpersonal violence. A large and nationally representative sample of adolescents (N = 4,023) responded to structured telephone interviews concerning mental health functioning (posttraumatic stress disorder-PTSD, major depressive disorder, substance abuse/dependence, and delinquency). Those reporting histories of sexual (n = 321) and/or physical (n = 688) assault were queried about specific aspects of their assaults, including their relationship with the perpetrator. After controlling for demographic and assault-related risk factors, the victim-perpetrator relationship remained a significant risk factor for mental health problems. Adolescents sexually assaulted by nonstrangers were at increased risk for PTSD; those sexually assaulted by acquaintances or people they did not know well were at increased risk for delinquency. Adolescents who were physically assaulted by a family member were at increased risk for PTSD. Explanations for the findings and the need for consistent assessment methods across related studies are discussed.     

Violence, Separation, and Loss in the Families of Origin of Domestically Violent Men

The intergenerational transmission of domestic violence is most commonly studied from the perspective of social learning theory, with the consequence that variables external to that perspective are often overlooked. This study was undertaken in an effort to broaden the theoretical basis of intergenerational transmission of domestic violence by assessing if incorporating variables from attachment theory (measures of separation and loss) with exposure to violence in family of origin would increase predictive power of a multiple regression model. Subjects (N = 74) were men in treatment for domestic violence. Separation and loss variables were found to exert effects on respondents’ violent behavior greater than or comparable to those from exposure to family of origin violence. Findings supported a need to broaden theoretical views of the etiology of domestic violence perpetration.     

Drug and alcohol use as determinants of New York City homicide trends from 1990 to 1998

In this population-level study, we analyzed how well changes in drug and alcohol use among homicide victims explained declining homicide rates in New York City between 1990 and 1998. Victim demographics, cause of death, and toxicology were obtained for all homicide (N = 12573) and accidental death victims (N = 6351) between 1990 and 1998 from the Office of the Chief Medical Examiner of New York (OCME). The proportion of homicide and accident decedents positive for cocaine fell between 1990 and 1998 (13% and 9% respectively); the proportion of homicide and accident decedents positive for opiates and/or alcohol did not change significantly. Changing patterns of drug and alcohol use by homicide victims were comparable to changing patterns of drug and alcohol use in accident victims, suggesting that changes in drug and alcohol use among homicide victims between 1990 and 1998 cannot solely explain the decline in NYC homicide rates.     

Forensic Applications of the Miller Forensic Assessment of Symptoms Test (MFAST): Screening for Feigned Disorders in Competency to Stand Trial Evaluations

Forensic evaluations must systematically assess malingering and related response styles. In the criminal forensic domain, competency to stand trial evaluations are the most common referrals. Effective screens for feigned incompetency would be valuable assets for forensic evaluations. This study evaluates the effectiveness of the Miller Forensic Assessment of Symptoms Test (MFAST) as a screen for feigned incompetency. Using a simulation design, the MFAST was tested on jail and competency-restoration samples. Most notably, recommended MFAST cut score (6) was useful for the identification of feigning cases in competency evaluations. Recommendations for forensic practice, including the advantages and disadvantages of systematic screens, are discussed.
