Competence to Waive Interrogation Rights and Adjudicative Competence in Adolescent Defendants: Cognitive Development,Attorney Contact,and Psychological Symptoms

Although there is growing evidence of developmental differences in competency to waive interrogation rights and adjudicative competence, the correlates of adolescents' legal capacities remain unclear. This study examined the relationship of legal capacities to cognitive development, legal learning opportunities, and psychological symptoms. Participants were 152 male and female defendants aged 11–17, who completed Grisso's Instruments for Assessing Understanding and Appreciation of Miranda Rights, the Fitness Interview Test (Revised Edition), the Woodcock-Johnson III Cognitive Assessment Battery, and the Brief Psychiatric Rating Scale for Children. Legal capacities relevant to interrogation and adjudication increased with age. These developmental differences were partially mediated or explained by cognitive development. Of the specific cognitive ilities examined (general intellectual ability, verbal ability, reasoning, long-term retrieval, attention, and executive functioning), verbal ability was a particularly strong predictor of performance on competency measures. Also, defendants obtained lower scores on competency measures if they showed evidence of attention deficits or hyperactivity, had spent limited time with their attorneys, and/or were from low socioeconomic backgrounds.     

Judicial Reform as Insurance Policy: Mexico in the 1990s

After seven decades of Mexican judicial subordination, President Ernesto Zedillo in 1994 introduced judicial reforms that increased the independence and judicial review powers of the judicial branch. The willful creation of a judiciary capable of checking the power of the president and the ruling PRI appears to counter political logic; but it makes sense as a political "insurance policy" to protect the ruling party from its rivals. PRI politicians, newly unable to control political outcomes at state and local levels and unsure if they would continue to dominate the national government in the future, opted to empower the Mexican Supreme Court as a hedge against the loss of office. This article argues that the likelihood of the reforms' producing an empowered judiciary increases as the ruling party's probability of reelection declines.     

Strengths,Limitations, and Recommendations for Instrumental Color Measurement in Forensic Soil Characterization

Color determination of soil evidence is often done by visual comparison to soil color charts. A handheld spectrophotometer was tested with representative materials for its suitability for forensic soil characterization. Instrumental colorimetry provides accurate colorimetry with ~10-fold better precision than a soil color chart. The minimum sample size for accurate color determination was between 0.02 and 0.04 mg of fine soil for the specific instrument tested. Reporting colors in the L*a*b* space permits quantification of ΔE₀₀, a measure of perceptible color difference, could enable objective quantification of small color differences and thresholds for forensic soil comparisons. A ΔE₀₀ greater than ~ 3.5 to 6 likely indicates disparate soil sources in a forensic comparison, in the absence of confounding factors like sample alteration. Despite the superior precision of instrumental colorimetry, this approach is inappropriate for samples which are mottled at an inseparable scale, attached to a substrate, or too small for instrumental measurement.     

Association of Contextual Factors with Drug Use and Binge Drinking among White, Native American, and Mixed-Race Adolescents in the General Population

Large-scale surveys have shown elevated risk for many indicators of substance abuse among Native American and Mixed-Race adolescents compared to other minority groups in the United States. This study examined underlying contextual factors associated with substance abuse among a nationally representative sample of White, Native American, and Mixed-Race adolescents 12–17?years of age, using combined datasets from the National Survey on Drug Use and Health (NSDUH 2006–2009, N?=?46,675, 48.77?% female). Native American adolescents displayed the highest rate of past-month binge drinking and past-year illicit drug use (14.06 and 30.91?%, respectively). Results of a logistic regression that included seven predictors of social bonding, individual views of substance use, and delinquent peer affiliations showed that friendships with delinquent peers and negative views of substance use were associated significantly with both substance abuse outcomes among White and Mixed-Race adolescents and, to a lesser extent, Native American adolescents. The association of parental disapproval with binge drinking was stronger for White than for Native American adolescents. Greater attention to specific measures reflecting racial groups’ contextual and historical differences may be needed to delineate mechanisms that discourage substance abuse among at-risk minority adolescent populations.     

Fear of Gang Crime: A Look at Three Theoretical Models

Gang crime and resulting public fear became a major policy focus during the 1990s, yet few studies specifically focus on fear of gang crime. Guided by social disorganization theory, we test three theoretical models about the individual thought processes leading to fear of gang crime. Using structural equation models, we find that each of these three theories—diversity, disorder, and community concern—is an important predictor of gang-related fear. In addition, we find that the indirect relationships between demographic characteristics, theoretical variables, and fear depend upon which model is tested.
