Community Mobilization and Community-Based Participatory Research to Prevent Youth Violence Among Asian and Immigrant Populations

Many community mobilization activities for youth violence prevention involve the researchers assisting communities in identifying, adapting, and/or tailoring evidence-based programs to fit the community needs, population, and cultural and social contexts. This article describes a slightly different framework in which the collaborative research/evaluation project emerged from the community mobilization activities. As will be discussed, this collaborative, sustained partnership was possible in the context of the Center on Culture, Immigration and Youth Violence Prevention's (UC Berkeley ACE) community mobilization activities that brought the issue of youth violence, particularly among immigrant and minority populations, to the forefront of many of the community partners' agendas. The East Bay Asian Youth Center (EBAYC) was one of the partners that came to the table, which facilitated the community-based engagement/mobilization. UC Berkeley ACE collaborated with EBAYC to evaluate an after-school program and an alternative probation program serving a diverse youth and immigrant population, including African Americans, Asians, and Hispanics. This article describes UC Berkeley ACE's community mobilization activity and the collaborative partnership with EBAYC, discusses how the evaluations incorporated community-based principles in design and practice, and presents some findings from the evaluations.     

Does theory of mind performance differ in children with early‐onset and regressive autism?

A deficit in theory of mind (ToM), or the ability to infer the mental states of others, has been implicated as one of the major characteristics of Autism Spectrum Disorder (ASD); however, little attention has been devoted to possible differences in ToM ability within ASD. The current study examined ToM performance in children with early-onset autism and regressive autism in comparison to typically developing children. Results indicated that children in the regressive autism group performed significantly better than the early-onset autism group on the non-verbal appearance-reality task. Additionally, Fisher's exact tests indicated a pattern of lowest scores in the early-onset group and highest scores in the typically developing group, whereas the regressive autism group tended to score in between the early-onset and typically developing groups. The apparent heterogeneity in ToM performance within ASD could account for the lack of universality in ToM ability found in previous studies.     

Quality assurance in the clinical genetics setting—Report of a workshop

Participants in a panel discussion sponsored by thead hoc Quality Assurance Committee of the National Society of Genetic Counselors discuss early efforts to develop and implement quality assurance instruments at institutional, state, and regional levels. Uniform guidelines and self-assessment tools can help genetic counselors and clinical geneticists to provide the best possible care to individuals affected by genetic diseases. Further work will be needed to address aspects not covered here and to assure that guidelines allow for creative variation among professionals and centers. An interdisciplinary approach to such standard-setting is recommended.CGC     

PEER TUTORING FOR CHILDREN WITH ATTENTION DEFICIT HYPERACTIVITY DISORDER: EFFECTS ON CLASSROOM BEHAVIOR AND ACADEMIC PERFORMANCE

We investigated the effects of classwide peer tutoring (CWPT) on the classroom behavior and academic performance of students with attention deficit hyperactivity disorder (ADHD). Typical instructional activities were contrasted with CWPT for 18 children with ADHD and 10 peer comparison students attending first- through fifth-grade general education classes. CWPT led to increases in active engagement in academic tasks along with reductions in off-task behavior for most participants. Of students with ADHD, 50% exhibited improvements in academic performance in math or spelling during CWPT conditions, as measured by a treatment success index. Participating teachers and students reported a high level of satisfaction with intervention procedures. Our results suggest that peer tutoring appears to be an effective strategy for addressing the academic and behavioral difficulties associated with ADHD in general education settings.     

Daily variation of multiple behaviors in Aplysia fasciata: integration of feeding, reproduction, and locomotion

Daily variations in feeding, reproductive behaviors, and activity level were examined under three conditions: (1) animals had access to food and mates; (2) there was access only to food; (3) neither food nor mates were present. Behaviors differed in amplitude of variations from their daily mean value. Egg-laying had the strongest tendency to be clustered. Amplitude of variations in courtship and swimming was larger than those of immobility, crawling, and feeding, while moving in place was the least clustered behavior. Changes in state affected the tendency to be clustered. When food and mates were present, amplitude of variations became progressively larger for immobility, moving in place, crawling, and swimming. Behaviors differed in the degree to which variations were patterned as a 1/day oscillation. Relatively little of the variability in crawling, moving in place, courtship, and egg-laying was due to a 1/day oscillation under any condition. By contrast, a large proportion of the variability of immobility, swimming, mating, and eating was modulated by a 1/day oscillation in at least one condition. The contribution of a 1/day oscillation to variability differed in the conditions examined. For immobility and swimming, when food and mates were present, the 1/day component of variability became smaller. By contrast, presence of mates led to an increase in the 1/day component of variability modulating feeding. Daily peaks of swimming and feeding were in phase with one another, and out of phase with mating and feeding. The ratio of locomotion to inactivity is constant, independent of change in external conditions. However, this ratio varied throughout the day. When food and mates were absent, variations of immobility and swimming were strongly related to variations in the inactivity ratio. When food and mates were added, this tendency decreased. The data suggest that daily variations in occurrence of behaviors can be accounted for by interactions between oscillators affecting Aplysia behavior and motivational variables. A 1/day oscillator has strong effects on mating, swimming, and immobility. The effect of the oscillator is modified by changes in motivational state.     

Randomized controlled trial of a brief problem-orientation intervention for suicidal ideation

Empirical evaluations suggest that problem orientation, the initial reaction to problems, differentiates suicidal youth from nonchnical controls and nonideating psychiatric controls. One promising area for intervention with suicidal youth relates to enhancing this specific coping skill. Nonclinical participants (N = 110) with active suicidal ideation were randomly assigned to receive a brief problem-orientation intervention or a control procedure. The current study evaluated the benefits of a brief prevention intervention based on the Problem-Solving Therapy model. Exposure to a brief video intervention regarding problem solving and coping skills was sufficient to elicit significant decreases in suicidal ideation and depression, but the intervention did not elicit improvements in problem orientation or other problem-solving abilities. These findings provide preliminary support for a brief, video-based problem-solving and coping skills module. However, considerable work in developing secondary prevention interventions remains.     

See what I mean? An ERP study of the effect of background knowledge on novel object processing

Two event-related potential (ERP) experiments were used to examine the representation of object feature information and background knowledge in semantic memory. Participants were trained on novel object categories with three features and were tested with new exemplars that were complete or were missing one to two features that were essential or nonessential to object function. In both a category membership judgment task (Experiment 1) and a parts detection task (Experiment 2), the N400, a functionally specific measure of semantic access, was graded with feature number but was insensitive to knowledge-based feature importance. A separable ERP effect related to knowledge was seen in Experiment 1 as an enhanced frontocentral negativity (beginning ∼300 msec) to exemplars missing a nonessential versus an essential feature, but this effect did not manifest when background knowledge was less task relevant (Experiment 2). Thus, similarity- and knowledge-based effects are separable, and the locus of knowledge effects varies with task demands but does not seem to arise from facilitated semantic access.     

Aging, Training, and the Brain: A Review and Future Directions

As the population ages, the need for effective methods to maintain or even improve older adults’ cognitive performance becomes increasingly pressing. Here we provide a brief review of the major intervention approaches that have been the focus of past research with healthy older adults (strategy training, multi-modal interventions, cardiovascular exercise, and process-based training), and new approaches that incorporate neuroimaging. As outcome measures, neuroimaging data on intervention-related changes in volume, structural integrity; and functional activation can provide important insights into the nature and duration of an intervention’s effects. Perhaps even more intriguingly, several recent studies have used neuroimaging data as a guide to identify core cognitive processes that can be trained in one task with effective transfer to other tasks that share the same underlying processes. Although many open questions remain, this research has greatly increased our understanding of how to promote successful aging of cognition and the brain.
