Location of Artifacts Deposited by the Blow Fly Lucilia cuprina After Feeding on Human Blood at Simulated Indoor Crime Scenes

Human DNA profiles can be obtained from fly artifacts (feces and regurgitant) when a fly has been feeding on biological material, sometimes 2 years after deposition. Morphological similarity between artifacts and spots of unaltered biological material make it difficult to distinguish between them, and presumptive and confirmatory forensic tests are unreliable in making the distinction. Knowing possible artifact locations will assist investigators in recognizing where DNA contamination might occur. Flies were released into a house with human blood available under a variety of different climatic and lighting conditions. The location of flies and artifacts was recorded after 72 h. It was found flies may move toward warm or well‐lit areas and deposit artifacts there, but artifacts were predominantly located around food sources and were often found in low positions. Factors such as ambient temperature, and the proximity of light and food sources, had an impact on where artifacts were deposited.     

Same Routines,Different Effects: Gender,Leisure, and Young Offending

The current study seeks to extend routine activity theory by examining how gender conditions the relationship between leisure activities and adolescent delinquency. Using OLS regression with a sample of high school students from Toronto (n = 2,209), we find that (1) engaging in more unstructured and unsupervised activities with peers is associated with delinquency more strongly for boys than for girls, but is associated with substance use equally across gender; (2) this pattern is likely due to gender differences in the locations or contexts of leisure activities; and (3) prosocial leisure activities are associated with less delinquency only for boys. In general, routine activity theory appears apt at explaining the substance use of boys and girls, but is less capable of explaining the property and violent offending of girls. We discuss our findings and their implications for the growing body of research extending routine activity theory to explain gender differences in delinquency.     

Role Conflict and the Psychological Impacts of the Post-Ferguson Period on Law Enforcement Motivation,Cynicism, and Apprehensiveness

In the wake of high-profile deadly force cases in the post-Ferguson era, a number of negative psychological outcomes have been depicted by law enforcement officers. We examine if negative post-Ferguson outcomes predict current cynicism, motivation, and apprehensiveness. Further, we account for whether role orientations, specifically support for a law enforcement orientation or a community policing orientation, mediate the psychological effects of the post-Ferguson period. Since the law enforcement orientation, exercised through strict enforcement of the law, has been called out of favor in the post-Ferguson area, supporting this role may negatively impact officers via role conflict. The opposite may be observed for those supporting a community policing orientation. We test these arguments using results from an online survey of law enforcement officers in the USA, administered 6 months following highly publicized incidents in Dallas and Baton Rouge where police were targeted and killed. Results showed that post-Ferguson psychological impacts continued to affect current levels of cynicism, motivation, and apprehensiveness. Support for law enforcement or community policing orientation did not mediate the effects of post-Ferguson sentiments. Nonetheless, role orientations played a significant role in predicting current cynicism, motivation, and apprehensiveness and provided support for the theory of role conflict.     

Authoritative school climate and suspension rates in middle schools: Implications for reducing the racial disparity in school discipline

The overuse of school suspensions has been linked to a host of negative outcomes, including racial disparities in discipline. School climate initiatives have shown promise in reducing these disparities. The present study used the Authoritative School Climate Survey—which measures disciplinary structure and student support as key measures of school climate—to investigate an association between teacher and student perceptions of school climate and suspension rates in a statewide sample of middle schools. Regression analyses controlling for school-level poverty and school size found that elements of authoritative climate, particularly structure, distinguish high- and low-suspending schools. Schools with high levels of student- and teacher-reported structure had lower overall suspension rates and a lower gap between Black and White suspension rates. These findings can be used to guide school climate initiatives to reduce racial disparities in school discipline.     

Delinquent recidivists: Vulnerable children

This study examines the relationship between vulnerability factors and recidivism by testing the hypothesis that first offenders who repeat delinquencies display more high-risk factors than those who do not repeat delinquencies. Four factors are identified which distinguish recidivists from nonrecidivists in a sample of first offenders matched by age and sex. Results are discussed from an epidemiological and early-intervention perspective.Data collected in 1980 were supported by the Research Associates, Clarke Institute of Psychiatry, University of Toronto, Toronto, Ontario, Canada.Received MSW from University of Michigan, 1972. Major research interests are juvenile delinquency and early intervention.Received Ph.D. in psychology from Washington University, St. Louis, Missouri, 1957. Major research interests are classification, juvenile delinquency, and psychological test development.Received Ph.D. in psychology from State University of New York at Buffalo, 1971.

THE WAR ON POVERTY: MEASUREMENT,TRENDS, AND POLICY

We present a 50‐year historical perspective of the nation's antipoverty efforts, describing the evolution of policy during four key periods since 1965. Over this half‐century, the initial heavy reliance on cash income support to poor families has eroded; increases in public support came largely in the form of in‐kind (e.g., Food Stamps) and tax‐related (e.g., the Earned Income Tax Credit) benefits. Work support and the supplementation of earnings substituted for direct support. These shifts eroded the safety net for the most disadvantaged in American society. Three poverty‐related analytical developments are also described. The rise of the Supplemental Poverty Measure (SPM)—taking account of noncash and tax‐related benefits—has corrected some of the serious weaknesses of the official poverty measure (OPM). The SPM measure indicates that the poverty rate has declined over time, rather than being essentially flat as the OPM implies. We also present snapshots of the composition of the poor population in the United States using both the OPM and the SPM, showing progress in reducing poverty overall and among specific socioeconomic subgroups since the beginning of the War on Poverty. Finally, we document the expenditure levels of numerous antipoverty programs that have accompanied the several phases of poverty policy and describe the effect of these efforts on the level of poverty. Although the effectiveness of government antipoverty transfers is debated, our findings indicate that the growth of antipoverty policies has reduced the overall level of poverty, with substantial reductions among the elderly, disabled, and blacks. However, the poverty rates for children, especially those living in single‐parent families, and families headed by a low‐skill, low‐education person, have increased. Rates of deep poverty (families living with less than one‐half of the poverty line) for the nonelderly population have not decreased, reflecting both the increasing labor market difficulties faced by the low‐skill population and the tilt of means‐tested benefits away from the poorest of the poor.     

The Effect of Pretrial Detention on Sentencing in Two Federal Districts

While a substantial body of research indicates that legal variables, such as offense severity and criminal history, principally shape sentencing decisions, other studies demonstrate that extralegal factors such as race, gender, and age influence sentencing outcomes, as well. The handful of studies focusing upon the effect of pretrial detention/release on sentencing outcomes indicate that pretrial detention is associated with greater lengths of incarceration. This study—the first to empirically examine the sentencing consequences of pretrial detention in the United States federal courts—employed a sample of 1,723 cases from two district courts (New Jersey and Pennsylvania Eastern). Pretrial detention and, to a lesser degree, revocation of granted pretrial supervision were associated with increased prison sentences; on the other hand, successfully completing a term of pretrial services supervision was associated with shorter sentence length. Implications for the federal criminal justice system are discussed.     

Protecting Ohio's Children: Ohio Juvenile Court Jurisdiction to Prevent Nonparty Interference in the Protection of the Best Interest of a Child

Ohio Rule of Juvenile Procedure 2(Y) allows juvenile courts to do what other courts cannot: designate additional parties to an action, allowing juvenile courts to better accomplish their statutory purpose of pursuing the best interests of children. However, sometimes this can lead to confusion about juvenile courts’ actions to protect children, especially when courts invoke Rule 2(Y) to stop interference with proceedings. This article will examine the historical foundations of Ohio's juvenile courts, the unique authority that they possess, and the conflicts that can arise due to interference with juvenile court proceedings. Ohio's juvenile courts have unique authority, and they can use that authority in a way that does not conflict with constitutional rights, while still working to protect the interests of children.     

Preaching to the Choir: Americans Prefer Communicating to Copartisan Elected Officials

Past work suggests that partisan attachments isolate citizens from encountering elite messages contrary to their points of view. Here, we present evidence that partisan attachments not only serve to filter the information citizens receive from political elites; they also work in the other direction, isolating politicians from encountering potentially contrary perspectives from citizens. In particular, we hypothesized that Americans prefer expressing their opinions to politicians who share their party identification and avoid contacting outpartisan politicians. Three studies—drawing on a mixture of observational, field experimental, and natural experimental approaches—support this hypothesis: Citizens prefer to “preach to the choir,” contacting legislators of the same partisan stripe. In light of evidence that contact from citizens powerfully affects politicians’ stances and priorities, these findings suggest a feedback loop that might aggravate political polarization and help explain how politicians of different parties could develop different perceptions of the same constituencies.
