Offense Characteristics of Incompetent to Stand Trial Defendants Charged With Violent Offenses

The current study compared offender and offense characteristics of pretrial defendants found incompetent to stand trial (IST) against those described as general offenders by victims in the 2008 Bureau of Justice Statistics (BJS) survey and evaluated factors that differentiated IST defendants who allegedly used weapons from those who did not during the course of a violent offense. IST defendants were older and used “weapons” more frequently than those reported in the BJS survey; however, other characteristics, including use of firearms, did not differ. No demographic, clinical, or legal factors differentiated pretrial defendants who used weapons from those who did not. Overall, pretrial defendants were frequently diagnosed with a comorbid substance use disorder, and were homeless, unemployed, and had an extensive history of psychiatric hospitalizations and prior arrests at the time of their alleged offenses. Such results indicate that models for comprehensive discharge planning may have utility in addressing the unique needs of this subgroup of mentally disordered offenders. The findings also raise questions about the federal and state prohibition of gun rights to all IST defendants. Copyright © 2015 John Wiley & Sons, Ltd.     

Same-sex harassment: implications of the Oncale decision for forensic evaluation of plaintiffs

The US Supreme Court recently rendered an opinion in Oncale v. Sundowner Offshore Services, Inc. (1998), holding that same-sex sexual harassment of a male by another male provides a basis for a title VII hostile work environment claim. Social scientists have recently begun to research same-sex sexual harassment. The data indicate that men are the predominant targets of intra-gender sexual harassment, and that patterns of same-sex harassment differ from those of inter-gender harassment. The clinical research on male victims of sexual abuse suggests that symptom pictures for same-sex victims may differ from models based upon women's experience of hostile work environments. Implications for social science research and clinical practice are discussed. Copyright © 1999 John Wiley & Sons, Ltd.     

Coding ethical behaviour: The challenges of biological weapons

Since 11 September 2001 and the anthrax attacks that followed in the US, public and policy concerns about the security threats posed by biological weapons have increased significantly. With this has come an expansion of those activities in civil society deemed as potential sites for applying security controls. This paper examines the assumptions and implications of national and international efforts in one such area: how a balance or integration can take place between security and openness in civilian biomedical research through devising professional codes of conduct for scientists. Future attempts to establish such codes must find a way of reconciling or at least addressing dilemmatic and tension-ridden issues about the appropriateness of research; a topic that raises fundamental questions about the position of science within society.     

Activism Against Nuclear Weapons Build-up—Student Participation in the 1984 Primary Campaigns1

This study presents longitudinal data concerning factors that influence student participation in political campaigns for candidates opposed to nuclear weapons build-up. Participation in campaigns was stimulated by nervousness about the nuclear arms race and the possibility of nuclear war, a feeling of moral obligation to act to try to prevent nuclear war, and several additional factors. The factors that contributed to participation in political campaigns are quite different from the factors found previously to be associated with other types of activism against nuclear weapons build-up. These findings suggest varied strategies for recruiting people to participate in different types of activism.     

Precision Weapons,Civilian Casualties,and Support for the Use of Force

Precision weapons such as drones have become important elements of the military strategies of the United States and other countries. How does the use of precision weapons influence public support for the use of force? The public is averse to casualties, mission failure, and collateral damage. I argue that precision weapons increase the salience and importance of avoiding civilian harm. Individuals adopt their expectations about the outcomes of using these weapons and have lower tolerance for attacks that result in civilian deaths. This proposition is consistent with the results of two survey experiments. In the first, the possibility of civilian casualties leads to larger declines in support for the use of force than do military casualties or mission failure. In the second, respondents primed with information about an attack with precision weapons exhibited less tolerance for civilian harm than those primed with other weapons systems, despite the fact that the outcomes described to all respondents were identical.     

The Relationship Between Parental Control and Scholastic Achievement of Children From Single- and Two-Parent Families

Abstract

A survey examined the relation between 264 Canadian students' value priorities (Rokeach, 1967) and their attitudes toward nuclear weapons and reasoning about the issue of allowing nuclear weapons in Canada. Regression analyses revealed that their attitudes became more favorable toward nuclear weapons as they placed more importance on the value of national security and less importance on peace. Over and above these attitudinal differences, however, they differed in the extent to which they regarded national security and peace as relevant to the issue of nuclear weapons. Hence, these findings were consistent with Kristiansen and Zanna's (1988) value justification hypothesis, which claims that people with different attitudes will attempt to justify them by appeals to different values. In addition, the degree to which subjects displayed integratively complex reasoning about nuclear weapons was a function of their attitudes: Those who opposed or favored nuclear weapons displayed less complex reasoning than those with more neutral attitudes. Finally, the integrative complexity of subjects' reasoning was not a function of the extent to which they deemed national security and peace as highly and equally important values. Possible explanations for this failure to replicate Tetlock's (1986) value pluralism model of ideological reasoning are considered.     

Testing Differential Item Functioning in Small Samples

Abstract

Differential item functioning (DIF) is a pernicious statistical issue that can mask true group differences on a target latent construct. A considerable amount of research has focused on evaluating methods for testing DIF, such as using likelihood ratio tests in item response theory (IRT). Most of this research has focused on the asymptotic properties of DIF testing, in part because many latent variable methods require large samples to obtain stable parameter estimates. Much less research has evaluated these methods in small sample sizes despite the fact that many social and behavioral scientists frequently encounter small samples in practice. In this article, we examine the extent to which model complexity—the number of model parameters estimated simultaneously—affects the recovery of DIF in small samples. We compare three models that vary in complexity: logistic regression with sum scores, the 1-parameter logistic IRT model, and the 2-parameter logistic IRT model. We expected that logistic regression with sum scores and the 1-parameter logistic IRT model would more accurately estimate DIF because these models yielded more stable estimates despite being misspecified. Indeed, a simulation study and empirical example of adolescent substance use show that, even when data are generated from / assumed to be a 2-parameter logistic IRT, using parsimonious models in small samples leads to more powerful tests of DIF while adequately controlling for Type I error. We also provide evidence for minimum sample sizes needed to detect DIF, and we evaluate whether applying corrections for multiple testing is advisable. Finally, we provide recommendations for applied researchers who conduct DIF analyses in small samples.     

The relationship of gender,sex role,and law-and-order attitudes to nuclear opinions

Australian students' attitudes to nuclear weapons were considered in relation to sex-role identification and political orientations. By including a measure of sex-role orientation, we hoped to clarify earlier confusion surrounding gender as a predictor of nuclear views. Our hypothesis was that men and women with feminine sex-role orientations would display the strongest antinuclear feelings. Also, we predicted that an authoritarian political stance advocating strict law-and-order on the domestic front would predict support for nuclear weapons in international defense. The subjects were 46 male and 62 female first-year university students. The measure of nuclear attitudes was a 23-item inventory (NARQ) which had previously been extensively refined and validated for Australian populations (Jennings & Lawrence, 1986). The BSRI (Bem, 1974) measured sex-role orientation. An Australian law-and-order scale was also developed for this research. Latent trait models for rating data were applied to NARQ and law-and-order scales. The results revealed sex differences on approximately one-third of the nuclear opinion items, with men expressing stronger support for nuclear weapons in every case. Authoritarian law-and-order attitudes likewise predicted support for nuclear weapons in both men and women. A stepwise multiple regression analysis showed that BSRI masculinity and law-and order made separate, statistically significant, contributions to overall variation in nuclear views. These results were considered in relation both to previous research and to practical implications for political behavior.     

The Genetic Testing of Children for Cancer Susceptibility: Ethical,Legal, and Social Issues

Genetic testing for cancer susceptibility raises many ethical, legal, and social concerns, particularly when testing children is considered. The complexity of defining medical and psychosocial risks and benefits of genetic predisposition testing for multifactorial disorders, like cancer, is discussed. Presumed incompetence of children and adolescents and questionable ability of many adults to understand complex genetic information raise informed consent questions. Guidelines can aid professionals but there must also be a means of evaluating individual cases. Further research is needed to determine optimal methods of educating children and adults about genetic issues and to discriminate factors which contribute to satisfaction with decision-making about genetic testing. Legal issues and practical considerations are examined involving a duty to warn family members about genetic susceptibility and to re-contact previously-tested individuals as knowledge advances. Recommendations are offered concerning roles for social scientists and legal scholars in ethical integration of genetic testing into our medical and social framework.     

Testing unidimensionality in polytomous Rasch models

A fundamental assumption of most IRT models is that items measure the same unidimensional latent construct. For the polytomous Rasch model two ways of testing this assumption against specific multidimensional alternatives are discussed. One, a marginal approach assuming a multidimensional parametric latent variable distribution, and, two, a conditional approach with no distributional assumptions about the latent variable. The second approach generalizes the Martin-Löf test for the dichotomous Rasch model in two ways: to polytomous items and to a test against an alternative that may have more than two dimensions. A study on occupational health is used to motivate and illustrate the methods.The authors would like to thank Niels Keiding, Klaus Larsen and the anonymous reviewers for valuable comments to a previous version of this paper.

Disarmament Decisions as Social Dilemmas1

The individual deciding on a nuclear weapons production policy is faced with a dilemma in which a choice must be made to support one of several conflicting defense policies. In order to investigate the social-psychological variables that are related to armament policy decision making, a telephone survey was conducted in the City of St. Louis, Missouri. Adult subjects (N= 110) responded to questions concerned with cognitive, attitudinal, and emotional responses to nuclear arms. Participants were also asked to choose a weapons production policy for the United States under conditions of continued and decreased Soviet nuclear arms production. Results indicated that respondents decisions about nuclear weapons production were related to their support for deterrence, the availability of their nuclear-related images, their emotional response to nuclear war, their attributions of responsibility for the prevention of nuclear war, and their political party affiliation. Distinctions between antinuclear decision-makers and pronuclear decision-makers are discussed.     

Weapons used by juveniles and adults to kill parents

Youths who kill, particularly those who kill their parents, have been a matter of increasing concern in the United States in recent years. Empirical analyses of homicide and parricide cases, however, have been limited. The FBI Supplementary Homicide Report (SHR) Data Base for the 10-year period 1977–1986 was utilized to investigate which weapons were used by children in the United States to kill male and female parents and stepparents in single victim, single offender situations. Biological parents were analyzed separately from stepparents. Significant differences were found in the weapons used to kill male and female parents, the weapons used by juveniles and adults when killing parents and stepfathers, and the weapons used by both juveniles and adults when killing male as opposed to female victims. The age and gender differences found in relation to weapons used to kill parents were consistent with a physical strength hypothesis. The relationship found between offender age and weapon used strongly suggests that the number of parricides committed by juveniles could be somewhat curtailed if access to firearms, particularly rifles and shotguns, was severely restricted.     

Routine screening: informed consent, stigma and the waning of HIV exceptionalism

The Centers for Disease Control and Prevention (CDC) recently recommended that HIV screening should become routine for all adults in the United States. Implicit in the CDC proposal is the notion that pre-test counseling would be more limited than at present, and that written informed consent to screening would no longer be required. If widely implemented, routine testing would mark a tremendous shift in the US HIV screening strategy. There are a number of considerations used to determine what screening tests should be routine, and HIV fits the bill in almost every regard. Yet the stigma associated with HIV infection remains, making the CDC's recommendation highly controversial. Will minimizing requirements for pre-test counseling and special written informed consent lead to unexpected or unwanted HIV testing, or do these stringent counseling and consent requirements needlessly scare people away? Will widespread and routine testing be associated with declining stigmatization, or will it drive some patients away from seeking desperately needed health care? These are high stakes questions, and we're about to find out the answers.     

Phase Changes in the BRCA Policy Domain

The recent US Supreme Court ruling against gene patenting has been accompanied by the passage at the federal level of the Patient Protection and Affordable Care Act, both events representing a thawing or phase change in policies that will now make preventive techniques, such as BRCA genetic testing to predict risk for familial breast and ovarian cancer, more affordable and accessible. Authors including Yun-Han Huang in this journal have noted the judicial ruling is one step—a significant one—in the process of patent system reform. This commentary links such changes with policy formation and action taken by members of diverse religious communities in the aftermath of the Human Genome Project and continuing in today’s genome sequencing area. Religious engagement has acted as a catalyzing force for change in the creation and dissemination of genetic developments. Religious perspectives are needed to solve the new ethical dilemmas posed by population screening for BRCA mutations and the rise of direct-to-consumer and provider marketing of such genetic tests, which have far-reaching consequences at the individual, family, and societal levels.     

Education for Life Scientists on the Dual-Use Implications of Their Research

Advances in the life sciences are occurring with extreme rapidity and accumulating a great deal of knowledge about life’s vital processes. While this knowledge is essential for fighting disease in a more effective way, it can also be misused either intentionally or inadvertently to develop novel and more effective biological weapons. For nearly a decade civil-academic society as well as States Parties to the Biological and Toxin Weapons Convention have recognised the importance of dual-use biosecurity education for life scientists as a means to foster a culture of responsibility and prevent the potential misuse of advances in the life sciences for non-peaceful purposes. Nevertheless, the implementation of dual-use biosecurity education for life scientists has made little progress in institutions of higher learning. Professional societies and academic organizations have worked from the bottom-up in developing online dual-use biosecurity education modules that can be used for instruction. However, top-down help is needed from goverments if further progress is to be made in implementing biosecurity education for life scientists.     

Juvenile homosexual homicide

Limited information exists on juvenile homosexual homicide (JHH), that is, youths who perpetrate sexual homicides against same-sex victims. Only a handful of cases from the United States and internationally have been described in the literature. This study, the first of its kind, examines the epidemiology, victimology, victim-offender relationship, and weapon-use patterns in JHH offenders using a large U.S. database on homicide spanning three decades. The data for this study were derived from the Federal Bureau of Investigation's Supplementary Homicide Reports (SHRs) for the years 1976 through 2005. A total of 93 cases of JHH were identified. On average, three of these crimes occurred annually in the U.S., and there was a marked decline in its incidence over the study period. Ninety-five percent were male offender-male victim cases and 5% were female offender-female victim cases. JHH offenders were over-represented amongst all juvenile sexual murderers, similar to their adult counterparts. The majority of these boys were aged 16 or 17 and killed adult victims. They were significantly more likely to kill adult victims than other age groups, to be friends or acquaintances of the victims, and to use contact/edged weapons or firearms. Most offenders killed same-race victims, although Black offenders were significantly more likely than White offenders to kill interracially. A case report is provided to illustrate JHH. Further research is needed to promote our understanding of the pathogenesis, etiology, and associated risk factors for this aberrant form of murder by children.     

A bird's eye view: biological categorization and reasoning within and across cultures

Many psychological studies of categorization and reasoning use undergraduates to make claims about human conceptualization. Generalizability of findings to other populations is often assumed but rarely tested. Even when comparative studies are conducted, it may be challenging to interpret differences. As a partial remedy, in the present studies we adopt a 'triangulation strategy' to evaluate the ways expertise and culturally different belief systems can lead to different ways of conceptualizing the biological world. We use three groups (US bird experts, US undergraduates, and ordinary Itza' Maya) and two sets of birds (North American and Central American). Categorization tasks show considerable similarity among the three groups' taxonomic sorts, but also systematic differences. Notably, US expert categorization is more similar to Itza' than to US novice categorization. The differences are magnified on inductive reasoning tasks where only undergraduates show patterns of judgment that are largely consistent with current models of category-based taxonomic inference. The Maya commonly employ causal and ecological reasoning rather than taxonomic reasoning. Experts use a mixture of strategies (including causal and ecological reasoning), only some of which current models explain. US and Itza' informants differed markedly when reasoning about passerines (songbirds), reflecting the somewhat different role that songbirds play in the two cultures. The results call into question the importance of similarity-based notions of typicality and central tendency in natural categorization and reasoning. These findings also show that relative expertise leads to a convergence of thought that transcends cultural boundaries and shared experiences.     

Adversary effects and the tactics of violent offenders

We examine the implication of adversary effects for target choice, lethal intent, and the use of weapons and allies in violent incidents. Adversary effects refer to the tendency of offenders to make tactical decisions based on the coercive power of victims and potential victims. Using the victim's gender as a proxy for coercive power, we analyzed violent incidents from the National Incident‐Based Reporting System (2005–2014). The sample included over six million assaults, robberies, and homicides. Consistent with adversary effects, offenders who attack males (vs. females) are more likely to (a) kill victims; (b) use guns, knives, blunt objects, poison, and automobiles; (c) use male (but not female) allies; and (d) use multiple allies. The evidence for target choice is mixed: unarmed female offenders, but not unarmed male offenders, are more likely to target females than males. The evidence shows how a simple theoretical principle can parsimoniously account for basic patterns of violence in society related to gender, weapons, and group violence.     

Predictive genetic testing for conditions that present in childhood

There is a general consensus in the medical and medical ethics communities against predictive genetic testing of children for late onset conditions, but minimal consideration is given to predictive testing of asymptomatic children for disorders that present later in childhood when presymptomatic treatment cannot influence the course of the disease. In this paper, I examine the question of whether it is ethical to perform predictive testing and screening of newborns and young children for conditions that present later in childhood. I consider the risks and benefits of (1) predictive testing of children from high-risk families; (2) predictive population screening for conditions that are untreatable; and (3) predictive population screening for conditions in which the efficacy of presymptomatic treatment is equivocal. I conclude in favor of parental discretion for predictive genetic testing, but against state-sponsored predictive screening for conditions that do not fulfill public health screening criteria.
