Determination of elemental sulfur in explosives and explosive residues by gas chromatography-mass spectrometry

A new method for the positive identification of elemental sulfur in explosives and explosive residues is developed. Following a carbon disulfide wash of explosives or explosive residues, a sample of the extracted material is injected onto a gas chromatography (GC) column, then analyzed via mass-selective (MS) detection. A positive identification of elemental sulfur is based on both retention time and fragmentation pattern. The GC-MS method is demonstrated to be useful in detecting and positively identifying elemental sulfur from both burned and unburned explosive mixtures. With a detection limit of 2.5 ng (2.5 x 10(-9) grams) of elemental sulfur on the column, it is shown to be 400 times more sensitive than the presumptive chemical color test that is currently the method employed for detection of small amounts of sulfur.     

Predictors of Child Abuse Potential Among Military Parents: Comparing Mothers and Fathers

The present study examines the predictors of child abuse potential for at-risk fathers and mothers serving as active duty Army members and their spouses. Although fathers are perpetrators of child physical abuse and neglect in a substantial portion of reported cases, what is known about factors associated with child maltreatment comes almost exclusively from studies of perpetrating mothers. Thus, the inclusion of a large sample of fathers in the present study makes a significant contribution to the extant literature. Participants were 175 fathers (93% active-duty) and 590 mothers (16% active duty) of young children enrolled in an Army-sponsored home visitation program. Regression analyses indicated that there were both common and unique predictors of child abuse potential for mothers and fathers. Common predictors included depression, parental distress, and family conflict. Low family expressiveness was predictive only for fathers, whereas marital dissatisfaction, low social support, and low family cohesion were predictive only for mothers. Possible reasons for these gender differences and the implications of these results for child maltreatment interventions are discussed.     

Adolescent Sexual Onset: An Intergenerational Analysis

Adolescents have begun to initiate sexual activity at increasingly early ages in the past few decades. Using a sample of 2,494 adolescents from the National Longitudinal Survey of Youth (NLSY97), structural and parental process variables were examined in the prediction of sexual onset. Results indicated that the age at which youth initiate sexual intercourse is related to the structural characteristics of their grandmothers and mothers, as well as puberty, gender, and race. There is support for partial mediation of the effects of these grandmother characteristics via mother characteristics and parental process. Results are discussed within the framework of the life course perspective and provide support for the importance of previous generations in the explanation of adolescent sexual behavior. Implications for families and adolescents are also addressed. Katherine A. Johnson, is a doctoral student at the University of Nebraska–Lincoln.

Women's participation in national-level politics and government: The case of Costa Rica

It has often been assumed that women in politics in Latin America approach their public responsibilities in a manner consistent with their traditional domestic roles. This article analyzes women's roles in Costa Rican politics and government through an examination of both the positions they hold and the attitudes they maintain regarding these positions. We conducted interviews in Costa Rica with female political elites and gathered data from mail questionnaires. It appears that Costa Rican women in public life are most likely to hold traditionally “female” positions and maintain both a feminine image and traditional family values. However, women in Costa Rican politics and government do not view their participation in the public sphere as an extension of their traditional domestic roles.     

Effects of Judicial Instructions and Case Characteristics in a Mock Jury Trial of Battered Women Who Kill

This study examined the effects of judicial instructions on the outcome of a mock jury trial that involved a woman who pleaded self-defense after killing her abusive spouse. Jurors were instructed to adopt either an objective or a subjective standard of reasonableness when reaching a verdict. Within objective/subjective instruction conditions, half of the juries viewed a case in which the woman killed her abuser while he was attacking her (confrontational) and the remaining half viewed a case in which she killed him while he was asleep (no confrontation). Juries in the subjective conditions returned significantly more not guilty verdicts than jurors in the objective conditions. At the individual juror level, participants hearing subjective instructions were significantly more likely to rate the defendant as not guilty than jurors given objective instructions when the abuse was nonconfrontational.     

In the eye of the beholder: Meaning and structure of informal status in women's and men's prisons*

Applying an abductive mixed‐methods approach, we investigate the informal status systems in three women's prison units (across two prisons) and one men's prison unit. Qualitative analyses suggest “old head” narratives—where age, time in prison, sociability, and prison wisdom confer unit status—are prevalent across all four contexts. Perceptions of maternal “caregivers” and manipulative “bullies,” however, are found only in the three women's units. The qualitative findings inform formal network analyses by differentiating “positive,” “neutral,” and “negative” status nominations, with “negative” ties primarily absent from the men's unit. Within the women's units, network analyses find that high‐status women are likely to receive both positive and negative peer nominations, such that evaluations depend on who is doing the evaluating. Comparing the women's and men's networks, the correlates of positive and neutral ties are generally the same and center on covariates of age, getting along with others, race, and religion. Overall, the study points to important similarities and differences in status across the gendered prison contexts, while demonstrating how a sequential mixed‐methods design can illuminate both the meaning and the structure of prison informal organization.     

Can Neck Contusions in Unexplained Pediatric Deaths be Explained by Cardiopulmonary Resuscitation?

The distribution of cutaneous contusions in infants may raise the possibility of maltreatment. Neck contusions are particularly problematic since they seldom occur outside the setting of abuse, while cardiopulmonary resuscitation (CPR)‐related maneuvers may involve the neck. To address the role of CPR in neck findings, we examined 260 consecutive pediatric autopsies in which CPR was attempted. No neck contusions were identified in manners of death classified as natural, undetermined, or suicide. Contusions were present in two of 80 deaths classified as accident and had obvious accidental causes. About 26% of deaths classified as homicide had neck contusions with no explanation provided by the caregiver (p < 0.0001). In conclusion, neck contusions in deceased children with no apparent explanation should be regarded as suspicious for abuse and investigated accordingly. CPR is not a plausible explanation for neck contusions in children.     

Law enforcement response to mental health crises: citizen risk factors and preferences for social policy*

Despite having the potential to affect cooperation and support for law enforcement, community preferences for police training are generally unstudied. This paper seeks to understand (1) general community preferences for police training for responding to mental health crises, (2) where the public prioritizes this mental health crisis training relative to racial bias training, and (3) whether these preferences vary depending on respondent demographics and risk factors for police contact. Survey data from a general sample of Portland, Oregon residents (N = 259) shows public support for police training on responding to mental health crises, but the public as a whole is split over whether mental health, or racial bias training, should be prioritized as the best use of police training time. Logistic regression analyses demonstrate three main findings regarding the impact of respondent characteristics on preferences for police training: (1) black respondents appear concerned that, by drawing attention to mental health crises, police will be more limited in their responses to racial bias; (2) respondents facing the greatest, and those with the least, amount of risk in police/citizen encounters are most supportive of mental health crisis training; and (3) mental illness itself does not appear to affect support for police mental health crisis training. These differences in support for training need to be understood before law enforcement can cultivate community support for police officers and their training practices.     

Framing innocents: the wrongly convicted as victims of state harm

We adapt the victimology of ‘state harms’ framework outlined by Kauzlarich et al. (Critical Criminology, 10(3), 173–194, 2001) to understand the post-exoneration experiences of 18 death row exonerees. Kauzlarich et al. develop six points of commonality shared by most victims of state crime. Application of this framework to death row exonerees highlights the role the state plays in creating and exacerbating the harms they suffer. This analysis also lays a foundation for further theoretical inquiry into the wrongful conviction of the innocent as a form of state crime.
