The relation of violence exposure and ethnicity to intelligence and verbal-performance discrepancies in incarcerated male adolescents

Incarcerated populations have an estimated incidence of intellectual disabilities (IDs) far higher than national norms, ranging as high as 10%. In the present study, the relation between ID and violence exposure in 115 incarcerated adolescents was examined. Interpersonal violence exposure (IPV-E) predicted an average decrease in full scale IQ of 4.5 points, explaining approximately 5% of the difference in IQ. Child maltreatment increased the odds of having a verbal disability by three folds and explained 17% of the variance in verbal disability. Hierarchical regression was used to examine the relative contribution of ethnicity, poverty, and violence exposure to intellectual functioning. The literature on racial bias in incarceration and the implications for the present study are discussed.     

Disregulated Alcohol-Related Behavior Among College Drinkers: Associations With Protective Behaviors,Personality, and Drinking Motives

Abstract

Objective: This study investigated the psychometric properties of the Disregulated Alcohol-Related Behaviors Inventory (DARBI), a measure of harmful alcohol-related behavior, and the relationship between protective behavior use and scores on the DARBI and several other measures. Participants: Participants were 281 undergraduate volunteers (60% female) enrolled in introductory psychology sections in Summer and Fall 2007. Methods: Participants completed the DARBI along with paper-and-pencil self-report measures of broad personality domains, trait resilience, protective behavior use, and drinking motivations and consequences. Results: The DARBI's internal consistency was good (alpha = .85). DARBI scores correlated negatively with conscientiousness scores but positively with neuroticism, the Michigan Alcohol Screening Test (MAST), Rutgers Alcohol Problem Index (RAPI), and positive-reinforcement motives scores. The self-reported use of protective behaviors related negatively to DARBI, MAST, RAPI, and enhancement motives scores. Protective behavior use was unrelated to broad personality domains. Conclusions: The DARBI may prove a useful tool in campus interventions. Further research should determine the dispositional and situational determinants of protective behavior use.     

Research Knowledge Assessment: A Study of MSW Students’ Acquisition and Retention of Research Knowledge

ABSTRACT

In response to the need for meaningful data about student learning in research courses, we developed and implemented the Research Knowledge Assessment instrument to measure MSW student acquisition, application, and retention of research knowledge over a 3-year period across the research curriculum. Initial findings indicated that students entered the foundation research methods course with little research knowledge, gained some knowledge during the course but not at an acceptable level, and lost 22% of the gain by the beginning of the concentration research course. The greatest knowledge acquisition was in sampling and the least in theory and question development. Knowledge acquisition was associated with not having a BSW and not having adjunct faculty as a research instructor.     

Life in the Mindful Classroom: Nurturing the Disposition of Mindfulness

In this article, we review the appropriateness of 'mindfulness' as an educational goal and explore what it means to cultivate mindfulness as a disposition, that is, as an enduring trait, rather than a temporary state. We identify three high-leverage instructional practices for enculturatingmindfulness: looking closely, exploring possibilities and perspectives, and introducing ambiguity. We conclude by exploring what it might look like to cultivate the trait of mindfulness within individual classrooms. This report includes a review of an experimental study of 'conditional instruction,' which explores mindfulness as a state, and then drawson a series of qualitative case studies of 'thoughtful' classrooms to provide an example of conditional instruction as it might serve to develop a disposition of mindfulness.     

Capacity-building needs of minority health nonprofits

This article reports on the results of a statewide assessment of the capacity-building needs of organizations that provide health services to ethnic minority groups in Ohio. The research addressed gaps in knowledge about the specific needs of these organizations for improved effectiveness and long-term sustainability. A telephone survey of 659 organizations, supplemented by focus groups with 37 participants in the state's largest cities, indicated substantial need and interest in capacity-building technical assistance in areas such as revenue-generating activities, marketing and public relations, information technology training, program evaluation, and board leadership development. The limited ability of these organizations to pay for the needed assistance creates challenges for planning approaches to meet these vital needs.     

Goodness of fit assessment of an alcohol intervention program and the underlying theories of change

The authors conducted an investigation of The Pennsylvania State University's Alcohol Intervention Program Level 2 (AIP2) to determine goodness of fit of the program components and its underpinning theories. They determined that the Health Belief Model, Social Norms Theory, Social Learning Theory, and the Transtheoretical Model Stages of Change and Process of Change are associated with AIP2's program elements. Although elements of AIP2 fit with these theories, gaps did exist within the program. The authors put forth recommendations for additional program elements that would strengthen the fit with these theories and enhance the program. In addition, upon examining the Transtheoretical Model Stages of Change and Process of Change in terms of sequence, the authors found that information from the readiness to change assessment was not being used to tailor the program elements to individual participant needs. Moreover, the postreadiness-to-change measure adapted by a prereadiness-to-change assessment was not useful in determining behavior change.     

Combining noisy images of small crystalline domains in high resolution electron microscopy

A technique is presented for enhancing and combining electron microscope images of small clystalline areas. Phases obtained by Fourier transforming electron micrographs are merged with available more precise amplitudes, in a Fourier synthesis, to obtain a final estimated image. The procedure is illustrated with 42 individual images of the purple membrane from Halobacterium halobium. To show the power of combination, results based on 1, 2, 4, 8, 16, 32 and 42 images are presented. An estimate based solely on the micrograph data, i.e. ignoring the precise amplitudes, is also presented and is seen to be notably poorer. The level of uncertainty of the final image is assessed by stimulating 10 final images and superposing the results.     

A BETTER ADDITIVE CONGRUENTIAL RANDOM NUMBER GENERATOR?

Roger L. Burford reported on a new additive congruential random number generator in the April, 1973 issue of Decision Sciences [1]. Burford claimed a number of advantages for the new generator, including a faster generation time than the commonly used multiplicative generators. This note describes an extensive examination of the Burford generator in comparison with the standard multiplicative generators recommended by Control Data Corporation [3] and IBM [2]. The results indicate that the multiplicative generators require much less computer time than the Burford additive generator. Further, the statistical validity of the Burford generator depends upon the initial numbers chosen for use.
