Tutoring is commonly employed to prevent early reading failure, and evidence suggests that it can have a positive effect. This article presents findings from a large-scale (n = 734) randomized controlled trial evaluation of the effect of Time to Read—a volunteer tutoring program aimed at children aged 8 to 9 years—on reading comprehension, self-esteem, locus of control, enjoyment of learning, and future aspirations. The study found that the program had only a relatively small effect on children’s aspirations (effect size +0.17, 95% confidence interval [0.015, 0.328]) and no other outcomes. It is suggested that this lack of evidence found may be due to misspecification of the program logic model and outcomes identified and program-related factors, particularly the low dosage of the program.

We develop a theoretical model of enforcement and compliance under HACCP regulation and use the FDA's seafood inspection records to examine: (1) if the FDA has targeted its inspections under HACCP regulation; (2) the effects of inspections on compliance with HACCP and plant sanitation standards; and (3) the relationship between compliance with HACCP and preexisting sanitation standards. There is some evidence of targeting based on product risk, but not on past compliance performance. The threat of an inspection increases the likelihood of compliance, but only for sanitation inspections, not for HACCP. HACCP compliance does not improve compliance with sanitation standards. © 2008 American Agricultural Economics Association.

For many years, orientation in migratory birds has primarily been studied in the laboratory. Although a laboratory-based setting enables greater control over environmental cues, the laboratory-based findings must be confirmed in the wild in free-flying birds to be able to fully understand how birds orient during migration. Despite the difficulties associated with following free-flying birds over long distances, a number of possibilities currently exist for tracking the long distance, sometimes even globe-spanning, journeys undertaken by migrating birds. Birds fitted with radio transmitters can either be located from the ground or from aircraft (conventional tracking), or from space. Alternatively, positional information obtained by onboard equipment (e.g., GPS units) can be transmitted to receivers in space. Use of these tracking methods has provided a wealth of information on migratory behaviors that are otherwise very difficult to study. Here, we focus on the progress in understanding certain components of the migration-orientation system. Comparably exciting results can be expected in the future from tracking free-flying migrants in the wild. Use of orientation cues has been studied in migrating raptors (satellite telemetry) and thrushes (conventional telemetry), highlighting that findings in the natural setting may not always be as expected on the basis of cage-experiments. Furthermore, field tracking methods combined with experimental approaches have finally allowed for an extension of the paradigmatic displacement experiments performed by Perdeck in 1958 on the short-distance, social migrant, the starling, to long-distance migrating storks and long-distance, non-socially migrating passerines. Results from these studies provide fundamental insights into the nature of the migratory orientation system that enables experienced birds to navigate and guide inexperienced, young birds to their species-specific winter grounds.

The effect of photon frequency redistribution by line branching on mass-loss rates for hot luminous stars is investigated. Monte Carlo simulations are carried out for a range of OB star models which show that previous mass-loss calculations which neglect non-resonance line scattering overestimate mass-loss rates for luminous O stars by ~20 per cent. For luminous B stars the effect is somewhat larger, typically ~50 per cent. A Wolf-Rayet star model is used to investigate line branching in the strong wind limit. In this case the effect of line branching is much greater, giving mass-loss rates that are smaller by a factor ~3 from computations which neglect branching.

The Newborn Individualized Developmental Care and Assessment Program (NIDCAP) is widely used in neonatal intensive care units and comprises 85 discrete infant behaviors, some of which may communicate infant distress. The objective of this study was to identify developmentally relevant movements indicative of pain in preterm infants.

The purpose of this study was to examine the challenges of integrating an asthma disease management (DM) program into a primary care setting from the perspective of primary care practitioners. A second goal was to examine whether barriers differed between urban-based and nonurban-based practices. Using a qualitative design, data were gathered using focus groups in primary care pediatric practices. A purposeful sample included an equal number of urban and nonurban practices. Participants represented all levels in the practice setting. Important themes that emerged from the data were coded and categorized. A total of 151 individuals, including physicians, advanced practice clinicians, registered nurses, other medical staff, and nonmedical staff participated in 16 focus groups that included 8 urban and 8 nonurban practices. Content analyses identified 4 primary factors influencing the implementation of a DM program in a primary care setting. They were related to providers, the organization, patients, and characteristics of the DM program. This study illustrates the complexity of the primary care environment and the challenge of changing practice in these settings. The results of this study identified areas in a primary care setting that influence the adoption of a DM program. These findings can assist in identifying effective strategies to change clinical behavior in primary care practices. © 2008 Mary Ann Liebert, Inc.
Evaluating program integration and the rise in collaboration:Case study of a palliative care network
Resumo:
Introduction: There is increasing global interest in using regional palliative care networks (PCNs) to integrate care and create systems that are more costeffective and responsive. We examined a PCN that used a community development approach to build capacity for palliative care in each distinct community in a region of southern Ontario, Canada, with the goal of achieving a competent integrated system. Methods: Using a case study methodology, we examined a PCN at the structural level through a document review, a survey of 20 organizational administrators, and an interview with the network director. Results: The PCN identified 14 distinct communities at different stages of development within the region. Despite the lack of some key features that would facilitate efficient palliative care delivery across these communities, administrators largely viewed the network partnership as beneficial and collaborative. Conclusion: The PCN has attempted to recognize specific needs in each local area. Change Is gradual but participatory. There remain structural issues that may negatively affect the functioning of the PCN.

Objectives: To determine patient satisfaction with a community hospital's respiratory rehabilitation program and to assess changes in patient physical and emotional function and quality of life. Design: Pre- and post-program measures were made on a variety of physiological and psychosocial factors. A modified version of the Chronic Respiratory Disease Questionnaire was administered before and after the 8-week multidisciplinary and comprehensive respiratory rehabilitation program. The post-program questionnaire also included a number of service delivery and patient satisfaction and quality-of-life questions. Setting: Respiratory Rehabilitation Program at St. Joseph's Hospital, a community hospital in Brantford, Ont., in active partnership with the Brant County Lung Association. Brant County is located in Central West Ontario, and has both urban and rural areas and a population of approximately 125 000 people. Participants: Twenty-nine patients, with a diagnosis of moderate to severe chronic obstructive pulmonary disease (COPD) who were referred to the Fall 1997 and Spring 1998 programs, were enrolled in the study. Outcome measures: Changes in physical and emotional function, health knowledge, skills mastery, quality of life and satisfaction with the program. Results: Twenty-one of 29 patients completed the program. Statistically significant and clinically important improvements were found between all pre- and post-program evaluation scores (distance walked, fatigue, dyspnea, emotional function, skills mastery and health knowledge). Participants were very satisfied with the program and felt it improved their quality of life. Conclusion: The positive outcomes reported rom randomized controlled trials of respiratory rehabilitation programs can be achieved in a community hospital setting.

Objective: To assess the contribution of organizational factors to implementation of 3 asthma quality measures: enrollment in a disease management program, development of a written treatment plan, and prescription of severity-appropriate anti-inflammatory therapy. Study design: A total of 138 pediatric clinicians and 247 office staff in 13 urban clinics and 23 nonurban private practices completed questionnaires about their practice's organizational characteristics (eg, leadership, communication, perceived effectiveness, job satisfaction). Results: 94% of the clinicians and 92% of the office staff completed questionnaires. When adjusted for confounders, greater practice activity and perceived effectiveness in meeting family needs were associated with higher rates of enrollment in the Easy Breathing program, whereas higher scores for 3 organizational characteristics-communication timeliness, decision authority, and job satisfaction-were associated with both higher enrollment and a greater number of written treatment plans. None of the organizational characteristics was associated with greater use of anti-inflammatory therapy. Conclusions: Three organizational characteristics predicted 2 quality asthma measures: use of a disease management program and creation of a written asthma treatment plan. If these organizational characteristics were amenable to change, then our findings could help focus interventions in areas of effective and acceptable organizational change. © 2009 Mosby, Inc.
