Reliability and Validity of Prisoner Self-Reports Gathered Using the Life Event Calendar Method

Data collection using the life event calendar method is growing, but reliability is not well established. We examine test–retest reliability of monthly self-reports of criminal behavior collected using a life event calendar from a random sample of minimum and medium security prisoners. Tabular analysis indicates substantial agreement between self-reports of drug dealing, property, and violent crime during a baseline interview (test) and a follow-up (retest) approximately 3 weeks later. Hierarchical analysis reveals that criminal activity reported during the initial test is strongly associated with responses given in the retest, and that the relationship varies only by the lag in days between the initial interview and the retest. Analysis of validity reveals that self-reported incarceration history is strongly predictive of official incarceration history although we were unable to address whether subjects could correctly identify the months they were incarcerated. African Americans and older subjects provide more valid responses but in practical terms the differences in validity are not large.     

Economic freedom, culture, and growth

How do economic freedom and culture impact economic growth? This paper argues that culture, as measured by the World Values Surveys, and economic institutions associated with economic freedom are both independently important for economic prosperity, but the strength of their impact can be better understood only when both are included in the growth regression. Our results indicate that economic freedom is more important than culture for growth outcomes, suggesting substitutability between the two. We posit that culture is important for growth when economic freedom is absent, diminishing in significance once economic freedom is established.     

Gender Differences in the Educational Expectations of Urban,Low-Income African American Youth: The Role of Parents and the School

This study examined how youths’ gender is related to the educational expectations of urban, low-income African American youth, their parents, and their teachers. As predicted, African American boys (ages 9–16) reported lower expectations for future educational attainment than did their female counterparts. Parents and teachers also reported lower expectations for African American boys (ages 6–16) than for girls. These findings held even when controlling for academic achievement. Contrary to predictions, the magnitude of the difference in expectations for males vs. females did not increase as a function of youths’ age. In keeping with our hypotheses, parental expectations fully mediated the relation between youths’ gender and youths’ expectations. Finally, certain school-based factors (i.e., positive teacher expectations and positive youth perceptions of the school environment) appeared to protect youths’ expectations from the deleterious impact of low parental expectations.

Effects of Victimization on the Belief in a Just World in Four Ex-Yugoslavian Countries

Levels of support for just world beliefs among young adults (N = 598) from four ex-Yugoslavian countries—Bosnia and Herzegovina, Croatia, the former Yugoslav Republic of Macedonia, and Slovenia—were compared, taking into account victimization experiences and the general belief in a just world. Being a victim affected an individual’s belief in a just world in the two less economically favored contexts: Victims of exclusion in Macedonia and victims of war in Bosnia and Herzegovina were less likely to believe in a just world than non-victims. These victimization variables partly explained why the mean scores of these two countries were less than those of the two others. A deleterious effect of cumulative negative events on belief in a just world was identified, in parallel with a lower endorsement of the belief when the first victimization occurred more recently.     

Non-biased lineup instructions do matter – a problem for older witnesses

Abstract

From the limited literature on older witnesses’ identification performance it is known that they are less accurate on lineups compared to younger witnesses. What is less certain is why they show this age deficit and what can be done to aid their performance. Witnesses forgot being given non-biased lineup instructions informing witnesses that the perpetrator may or may not be present. More older witnesses than younger witnesses forgot and witnesses who failed to report remembering these instructions were significantly less accurate on the lineups. In addition, the current study investigated the use of sequential lineup presentation and stringent decision criteria to aid the performance of older witnesses. Sequential presentation was beneficial to both younger and older adults when the lineup was target absent (TA) but was detrimental when the lineup was target present (TP). Stringent decision criteria had no significant beneficial effect. Future directions for aiding older witnesses’ performance are discussed.
