Strength Training Effects on Muscle Forces and Contributions to Whole-Body Movement in Cerebral Palsy

Strength training is often prescribed for children with cerebral palsy (CP); however, links between strength gains and mobility are unclear. Nine children (age 14?±?3?years; GMFCS I-III) with spastic CP completed a 6-week strength-training program. Musculoskeletal gait simulations were generated for four children to assess training effects on muscle forces and function. There were increases in isometric joint strength, but no statistical changes in fast-as-possible walking speed or endurance after training. The walking simulations revealed changes in muscle forces and contributions to body center of mass acceleration, with greater forces from the hip muscles during walking most commonly observed. A progressive strength-training program can result in isometric and dynamic strength gains in children with CP, associated with variable mobility outcomes.     

Churches as Neighborhood Organizations and Their Relationship to Street and Domestic Violent Crime: The Role of Denomination,Stability, and Heterogeneity

Recent developments in both theory and research on neighborhood crime have focused attention on the role of organizations. The current research builds on the existing literature to examine the relationship of churches to neighborhood “street” and domestic violence. The findings suggest that churches are fairly stable neighborhood organizations and not importantly heterogeneous, and neither factor appears to be related to neighborhood crime. Alternatively, the number of churches in a neighborhood is positively related to both street crimes and domestic assaults, and denomination does play an important role especially as it relates to domestic assaults. Theoretical and empirical implications are discussed.     

Prevalence of Alcohol Use and Reasons for Drinking Among Occupational Therapists: An Exploratory Investigation

Alcohol use by occupational therapists (OTs) and reasons for consuming alcohol were examined. Five hundred participants, randomly selected from American Occupational Therapy Association membership, were mailed surveys, resulting in 165 completed returns. The majority reported drinking alcohol generally for social-interactive motives, consuming one or two drinks one to four times per month. Two-fifths were found to drink intermittently in a potentially unhealthy manner. The percentage of OTs likely consuming alcohol at harmful levels, though comparatively small, is sufficient to warrant consideration by the profession to address the implications of potential alcohol misuse among a segment of its practitioners.     

RECONSIDERING THE MARGINS

Thousands of testimonies were collected in the immediate post-war period from child survivors of the Holocaust. These testimonies tell us much about the children's Holocaust experience and about society's attitude to child survivors. This paper presents an in-depth analysis of two such testimonies on the backdrop of historical research of their setting and context. Through our analysis of two children's testimonies given in the Aschau DP Children's Camp, we demonstrate that it is crucial to explore the immediate context in which testimonies were given, because of its strong influence upon their content and structure. In fact, our research shows that the contemporary context enters into the very fabric of the testimonies. No analysis, therefore, is complete without an inquiry into this crucial aspect. The two testimonies were chosen because they make up a distinct subgroup within a larger collection of testimonies that were given concurrently and, therefore, they constitute each other's immediate context. This paper also demonstrates the indispensability of a multidisciplinary analysis that draws upon elements from the fields of historical, literary and linguistic scholarship.     

Impact of contextual constraint on vocabulary acquisition in reading*

The current study investigated the influence of contextual constraint (strong versus moderate) on incidental vocabulary acquisition in reading, as eye movements of adult skilled readers were monitored. Surprise post-tests followed the reading session, and eye movement behaviour was directly connected to retention data. Longer and more frequent reading/rereading was associated with trials containing a novel target (rather than a known control), and unique patterns of connective rereading between constraint conditions were observed. For reading measures reflecting target word processing and connecting target with context, fixations were generally longer and more frequent for moderate constraint than for strong. The exception was in rereading of informative context, which was generally longer for strong constraint. More and longer fixations while connecting novel targets with informative context proved critical for novel word retention, significantly so for moderate constraint but not for strong, based on eye movement data associated with memory for novel word stimuli.     

Music and Video as Distractors for Boys with ADHD in the Classroom: Comparison with Controls,Individual Differences,and Medication Effects

This study examined the effects of music and video on the classroom behavior and performance of boys with and without attention deficit hyperactivity disorder (ADHD) and examined the effects of 0.3 mg/kg methylphenidate (MPH). In one study, 41 boys with ADHD and 26 controls worked in the presence of no distractor, music, or video. Video produced significant distraction, particularly for the boys with ADHD, and MPH improved the performance of boys with ADHD across distractor conditions.There were individual differences in response to the music such that some boys were adversely affected and others benefited relative to no-distractor.In a second study, music and MPH were assessed in an additional 86 boys with ADHD to examine further the music results. In the presence or absence of music, MPH improved performance relative to placebo. Similar individual differences were found as in Experiment 1.     

A demonstration of dual-task performance without interference in some older adults

Highly efficient dual-task processing is demonstrated when reaction time to each of two tasks does not differ between the dual-task situation and the single-task situation. This has been demonstrated reliably in younger adults; nevertheless, the two extant studies of extensive dual-task training did not find evidence for it in any elderly adult. The origins of age-related differences after training were explored in a study in which the stimuli for the two tasks were perfectly redundant although two distinct responses were required. The dual-task situation thus greatly reduced the demands of stimulus categorization while still requiring two response selections and two response executions. After only limited training 8 of 8 younger adults and 5 of 8 older adults showed performance consistent with highly efficient processing. Three older adults failed to show this even after 12 training sessions. The results implicate stimulus categorization more than response selection as an important locus of inefficient dual-task processing, particularly for older adults.     

Behavior analysts in the war on poverty: A review of the use of financial incentives to promote education and employment

Poverty is a pervasive risk factor underlying poor health. Many interventions that have sought to reduce health disparities associated with poverty have focused on improving health‐related behaviors of low‐income adults. Poverty itself could be targeted to improve health, but this approach would require programs that can consistently move poor individuals out of poverty. Governments and other organizations in the United States have tested a diverse range of antipoverty programs, generally on a large scale and in conjunction with welfare reform initiatives. This paper reviews antipoverty programs that used financial incentives to promote education and employment among welfare recipients and other low‐income adults. The incentive‐based, antipoverty programs had small or no effects on the target behaviors; they were implemented on large scales from the outset, without systematic development and evaluation of their components; and they did not apply principles of operant conditioning that have been shown to determine the effectiveness of incentive or reinforcement interventions. By applying basic principles of operant conditioning, behavior analysts could help address poverty and improve health through development of effective antipoverty programs. This paper describes a potential framework for a behavior‐analytic antipoverty program, with the goal of illustrating that behavior analysts could be uniquely suited to make substantial contributions to the war on poverty.
