Commitment and Consequences: Reneging on Cosponsorship Pledges in the U.S. House

We argue that bill cosponsorship in Congress represents an institutional arrangement that provides credibility to commitments of support. We predict that if cosponsorship fosters legislative deals, MCs will only rarely back out on their pledges to support a bill if it comes up for a floor vote, and when they do, these choices will reflect strategic calculations. Further, legislators who violate their cosponsorship agreements will face punishment from colleagues, compromising their ability to gain support for their own bills. We explore the causes and effects of MCs' choices to renege on a pledge by voting no on a bill for which they were a cosponsor, focusing on all cosponsorship decisions in the 101st–108th Houses. The results reveal that patterns of reneging and its consequences are consistent with the idea that cosponsorship functions as a commitment mechanism.     

The Severe 5%: A Latent Class Analysis of the Externalizing Behavior Spectrum in the United States

Objective

Criminological research consistently demonstrates that approximately 5% of study populations are comprised of pathological offenders who account for a preponderance of antisocial behavior and violent crime. Unfortunately, there have been no nationally representative epidemiological studies characterizing the severe 5% group.

Materials and Methods

Data from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative sample of 43,093 non-institutionalized U.S. residents aged 18 years and older were analyzed using latent class analysis to assess sociodemographic, psychiatric, and behavioral characteristics.

Results

Four-classes of respondents were identified vis-à-vis lifetime externalizing behaviors. A normative class (66.1% of respondents) demonstrated little involvement in antisocial conduct. A low substance use/high antisocial behavior class (20.7% of respondents) and high substance use/moderate antisocial behavior (8.0% of respondents) class evinced diverse externalizing and psychiatric symptoms. Finally, a severe class (5.3% of respondents) was characterized by pathological involvement in more varied and intensive forms of antisocial and externalizing behaviors and extensive psychiatric disturbance.

Conclusions

The current study is the first nationally representative epidemiological study of criminal careers/externalizing behavior spectrum in the United States and validates the existence of the 5% pathological group demonstrated by prior research.     

Predictors of suicidal ideation, suicide attempts, and self-harm without lethal intent in a community corrections sample

Purpose

Little published research data exist about suicidal ideation and self-harm behavior in community corrections and we seek to fill this void.

Aims

To examine the effects of drug dependence, depression, anxiety, psychopathy, fracture, and child trauma on suicidal ideation, suicide attempts, and self-harm without lethal intent in community corrections.

Methods

The Semi-Structured Assessment for the Genetics of Alcoholism Revised (SSAGA II) and the screening version of the Hare Psychopathy Checklist (PCL:SV) were administered. Separate binary logistic regression analyses were used to predict lifetime suicidal ideation, suicide attempt, and self-harm behavior.

Results

Prevalences of suicidal ideation, suicide attempt, and self-harm without lethal intent were 41%, 19%, and 14%. Suicidal ideation was predicted by drug dependence, elevated PCL:SV Factor 2 score, and Caucasian race. Suicidal ideation and attempt were both predicted by fractures, depression, and child trauma. Self-harm was predicted by fractures, panic, PCL:SV score, and child trauma.

Conclusions

Child trauma and multiple fractures are potent predictors for suicidal ideation, suicide attempts, and self-harm without lethal intent in this community corrections sample. Depression predicted suicidal ideation and attempts, while panic predicted self-harm without lethal intent. Psychopathy was also an important predictor of suicidal ideation and self-harm behaviors without lethal intent.     

Evaluation of age estimation technique: testing traits of the acetabulum to estimate age at death in adult males

This study evaluates the accuracy and precision of a skeletal age estimation method, using the acetabulum of 100 male ossa coxae from the Grant Collection (GRO) at the University of Toronto, Canada. Age at death was obtained using Bayesian inference and a computational application (IDADE2) that requires a reference population, close in geographic and temporal distribution to the target case, to calibrate age ranges from scores generated by the technique. The inaccuracy of this method is 8 years. The direction of bias indicates the acetabulum technique tends to underestimate age. The categories 46-65 and 76-90 years exhibit the smallest inaccuracy (0.2), suggesting that this method may be appropriate for individuals over 40 years. Eighty-three percent of age estimates were ±12 years of known age; 79% were ±10 years of known age; and 62% were ±5 years of known age. Identifying a suitable reference population is the most significant limitation of this technique for forensic applications.     

Spousal violence among Anglos,Blacks, and Mexican Americans: The role of demographic variables,psychosocial predictors,and alcohol consumption

Racial/ethnic differences in the prevalence and correlates of self-reported spousal violence in a community sample of Anglo, Black, and Mexican American adults are examined. Females, the formerly married, and Black females in particular (up to 60% of formerly married) were most likely to report both being beaten by and beating a spouse. Multivariate analyses controlling for demographic variables, financial stress, social desirability, sex role traditionalism and drinking quantity (and spouse's drinking among the currently married) did not eliminate the greater likelihood of reports of both beating and being beaten among married Black females. There was little consistent evidence to suggest greater violence propensity among Mexican American than Anglo respondents. The findings raise questions about simplistic socioeconomic status or financial stress explanations of observed racial/ethnic differences in spousal violence. Further, curvilinear effects of alcohol quantity and spouse drinking upon reported violence question simple disinhibition arguments and suggest the need for data regarding couple dynamics.     

Adolescents' Intergroup Attributions: A Comparison of Two Social Identities

This study investigated the intergroup perceptions of 2 social groups. English adolescents aged 14–15 years were asked to make causal attributions for various positive and negative behaviors performed by members of an in-group and an out-group. In the first condition (n = 45), participants rated members of their own peer group and members of a peer group to which they did not belong. Participants in the second condition (n = 45) rated English adolescents and members of a national out-group (either France or Germany). Results showed that participants in both conditions reported perceptions that were biased towards the formation of a favorable in-group evaluation. However, the relationship between intergroup discrimination and identification with the in-group was in the expected direction for participants in the peer group condition only. This observation is explained in terms of the potential level of identity threat posed by the prevalent intergroup context.
