Adolescent Impulsivity: Findings From a Community Sample

Impulsivity is central to several psychopathological states in adolescence. However, there is little consensus concerning the definition of impulsivity and its core dimensions. In response to this lack of consensus, Whiteside and Lynam (2001, Pers. Individ. Differ. 30, 669–689) have developed the UPPS Impulsive Behavior Scale, which is able to distinguish 4 dimensions of impulsivity in adults: Urgency, lack of Premeditation, lack of Perseverance, and Sensation seeking. The question arises of whether these 4 dimensions also exist in adolescents and also of whether gender differences can be observed. A sample of teenagers (314 girls and 314 boys) completed a French version of the scale (Van der Linden et al., Eur. J. Psychol. Assess., 2005). Based on exploratory and confirmatory analyses, the 4-factor model is replicated in girls, boys, and the whole sample. Concerning gender differences, girls have a higher score for Urgency and boys a higher score for Sensation seeking. Overall, this study suggests that the UPPS is a promising tool for studying impulsivity in adolescence.

The Impact of School Mental Health Services on Out-of-School Suspension Rates

The current study investigated whether the presence of school-based mental health clinicians in an urban school district was associated with reduced out-of-school suspension rates. Forty one elementary schools with expanded school mental health (ESMH) programs were compared to 41 schools without ESMH programs. Correlational analyses revealed associations between suspension outcomes and several school-level demographic variables including school attendance rate, percent of students in poverty, and percent of nonwhite students in the school. After controlling for these variables, however, results of stepwise linear regressions demonstrated no significant differences between ESMH and non-ESMH schools on suspension outcomes. Results of the current study suggest that the presence of ESMH clinicians will not necessarily impact suspension rates in an elementary school. Targeted and well-implemented approaches to address behaviors that lead to suspension, or school- and system-level policies to provide alternatives to suspensions, will likely be a better route to achieving this outcome.     

Informing Juvenile Justice Policy: Directions for Behavioral Science Research

Recent policy initiatives threaten to reduce the rehabilitative mission of the juvenile court or eliminate the court entirely. This article lays out a framework for an empirical assessment of these developments. It first evaluates the available and potential empirical support for three hypotheses about juveniles that might justify maintaining a separate, rehabilitation-oriented juvenile justice system: the hypotheses that, compared to adults, juveniles are more treatable, less culpable, and less deterrable. On the assumption that the continued existence of a rehabilitation-oriented juvenile court can be justified, it then provides suggestions as to how existing intervention strategies for juveniles could benefit from research attention to several substantive and methodological issues. These include refining outcome criteria and sampling strategies, matching offender and program characteristics, reexamining intervention efficacy, and focusing on decision makers and resource allocations.     

Validation of the Propensity for Abusiveness Scale in Diverse Male Populations

The Propensity for Abusiveness Scale (PAS; Dutton, 1995) was designed as a self-report perpetrator profile for intimate abusiveness. It was empirically validated through reports of abuse by intimate partners. The original PAS (Dutton, 1995) was given to 144 men in treatment for partner abuse and 44 demographically matched controls. It correlated significantly with partner reports of abusiveness and correctly classified men 82.2% of the time, as one standard deviation above or below the mean partners' report score for abusiveness. In the present study, the PAS was given to clinical outpatients, gay males, male college students, and a group of spousal assaulters. A criterion measure for abusiveness (the Psychological Maltreatment of Women Inventory; Tolman 1989, or the Psychological Maltreatment Inventory; Kasian & Painter, 1992) was collected from intimate partners. In all groups, the PAS correlated significantly with partners' reports of both physical and psychological abusiveness on subscales of the criterion measures: Dominance/Isolation and Emotional Abuse. For the college students and wife-assault groups, a new criterion measure was used: the Severity of Violence Against Women Scale. The PAS correlated significantly with partners' reports of threats and violence measured by this scale. The PAS appears to provide a nonreactive assessment instrument that is a strong predictor of intimate abusiveness across a variety of populations.     

Industry–University Research Centers: A Multivariate Analysis of Member Retention

Although a growing literature documents the benefits of industry–university research centers, most centers experience a significant amount of turnover among their industrial members. In order to gain a better understanding of this phenomenon, the current study attempts to identify factors that predict member renewal (DV). Questionnaire data were collected from industrial respondents (N=249) participating in 39 centers funded by the NSF IUCRC program. Structural, member benefits and administrative process variables were used to predict the dependent variable. Logistic regression analyses identified three significant predictors: professional networking benefits, research relevance and administrative operations. Implications of these findings for public policy, cooperative research management and future research are discussed.     

Reactions to Perceived Fairness: The Impact of Mortality Salience and Self-Esteem on Ratings of Negative Affect

In correspondence with terror management theory, the findings of two experiments show that reminders of death lead to stronger effects of perceived fairness on ratings of negative affect. Furthermore, in line with the theory's self-esteem mechanism, results of Experiment 1 suggest that state self-esteem may mediate this relationship between mortality salience and fairness. In further correspondence with the self-esteem mechanism, findings of Experiment 2 reveal that introducing an activity (after reminders of death and before the fairness manipulation) with which people can reaffirm positive conceptions of themselves leads people to react less strongly to variations in fairness than not introducing such a self-affirmation activity. These findings suggest that people react especially strongly to perceived fairness when they are in need for a boost in their self-esteem. Implications for the psychology of fairness are discussed.     

Explaining Ethnic Autonomy Regimes in Latin America

Through a systematic examination of nine cases, the author identifies factors that enabled indigenous movements in five Latin American countries to secure formal recognition of politico-territorial autonomy regimes. All nine cases occurred within the framework of a larger regime bargain—either (1) peace talks intended to end armed struggle when the regime faced a serious challenge to maintain political order or territorial control, or (2) a severe crisis of legitimacy and governability that forced political elites to renegotiate fundamental regime structures via the process of constitutional reform. In the five successful cases, changes in the political opportunity structure occurred that favored indigenous autonomy claimants. These changes were the opening of access to decision-making spheres and the emergence of an influential ally.

Enhancing the quality of aged latent fingerprints developed by superglue fuming: loss and replenishment of initiator

The recovery and identification of latent fingerprints from a crime scene are crucial to many investigations. The cyanoacrylate (superglue) fuming method (CFM), which develops fingerprints by growing a polymer coating over the print residue, is a powerful method but encounters severe limitations when prints are aged or exposed to harsh environmental conditions. We examine the aging process and how the changes that occur to a fingerprint residue over time influence the growth of polymer during development. We identify loss of initiator by erosion and degradation that, when coupled with a loss of water from the print residue, result in a decreased ability to polymerize ethylcyanoacrylate. Then, we present a methodology by which the ability of aged latent fingerprints to polymerize ethylcyanoacrylate is recovered. Two print enhancement agents, acetic acid and ammonia, are demonstrated to improve the growth of polymer from the print ridges by over an order of magnitude, while retaining the integrity of the print structure. Comparison between the two enhancement agents indicate that the enhancement occurs due to ridge coating by the ammonia or acetic acid and pH control of the latent print.
