Purpose: To conduct a systematic review of the evidence regarding the efficacy of exercise training in the management of cystic fibrosis (CF).Methods: Articles were found by searching PEDRO, MEDLINE, and CINAHL databases. Included articles involved exercise-related interventions for long-term adaptations (ie, not acute effects of exercise). Articles were excluded if the language was other than English or if other non-exercise interventions were used. Date of publication was not a factor for exclusion. Two independent reviewers evaluated the included articles using Sackett''s levels of evidence and select scoring criteria.Results: Twelve articles were eligible for inclusion. Interventions studied included various aspects of exercise training: anaerobic, aerobic, or resistance training. Study end-points included pulmonary function, aerobic capacity, strength, and health-related quality of life (HRQL).Conclusions: Exercise training in individuals with CF is beneficial, with aerobic and resistance training having the greatest support in the literature for improved aerobic capacity and strength, respectively. Exercise training does not appear to have an effect of improving pulmonary function, but may have a preservation effect. Strong conclusions about improvement in HQRL from exercise training cannot be made. However, greater consistency in measuring this outcome is needed in future trials. There is a paucity of evidence regarding the role of exercise training in reducing hospitalization and health care utilization, and questions raised by this review should be considered in the design of future trials.Key Words: cystic fibrosis, aerobic exercise, review  相似文献

The effects of ability grouping in schools on students' self-concept were examined in a sample of 23 secondary schools with a range of structured ability groupings. Measures of general self-concept, academic self-concept, and achievement were collected from over 1600 students aged 14–15 years and again two years later. Students' academic self-concept, but not their general self-concept, was related to the extent of ability grouping in the school attended. Subject-specific facets of academic self-concept were not related to the number of years of ability grouping students had experienced in English, mathematics and science; however, they were related to students' position in the grouping hierarchy, with students in high-ability groups having significantly higher self-concepts in all three subjects than students in low-ability groups. Students' intentions to learn in future were more strongly affected by self-concept than by achievement.  相似文献

This study examines the problem of identification of important authors in science by examining authors in the area of quantum mechanics. An examination was conducted using two methods of identification. The first method was a bibliometric approach and the second a historical approach. A gamma test of association was employed resulting in a finding of significant association between the ranks of authors. The major conclusion was that, when restricted to the same authors, the two methods of identifying important authors produce a statistically significant number of equivalent names. Discussion of the results and areas for further investigation are included.  相似文献

To improve educational services to students with disabilities, the United States government has mandated that each state develop a Comprehensive System of Personnel Development. The following article highlights the results of a state-wide needs assessment conducted by one state's Department of Education in order to tailor their system of personnel development. Four percent of the state's general educators, and 6% of the state's special education teachers completed the surveys for a total of 289 surveys. Perceptions of ability to positively affect students, understanding of inclusion, self-efficacy in serving students in inclusive settings, the need for inservice training in various areas, and the availability of supports to promote inclusion were examined for both special and general education teachers. In every area assessed, special education teachers rated their efficacy, ability, understanding, and resources higher than general education teachers. These results are discussed in terms of meeting professional development needs for both groups of teachers.  相似文献

ABSTRACT

Research Findings. The current study is a mixed-methods investigation of family child care provider participation in voluntary Quality Rating and Improvement Systems (QRIS) in 2 states. Study 1 is an analysis of matched QRIS and child care licensing administrative data extracted from both states in May, 2014. Poverty and population density variables were added to the dataset by aligning U.S. Census data and Rural Urban Commuting Area codes (RUCA) to the matched state child care data. Participation patterns differed in the 2 states relative to provider characteristics (subsidy receipt, years licensed, and location). Study 2 consists of focus groups with participating (n = 22) and non-participating (n = 19) providers. Professionalism and financial incentives emerged as significant in attracting family child care providers to QRIS. Although family child care providers identified several clear benefits to QRIS, many more challenges emerged that negatively impact their participation. Practice or Policy. As most states are employing a QRIS framework to integrate quality improvement efforts, perspectives from this sector of early care and education are often overlooked. Study findings suggest that QRIS can be more responsive and effective with family child care providers if more consideration of their unique features are considered in systems design and implementation.  相似文献

In 1997, the DfEE suggested that schools should consider 'setting' pupils by ability as it was believed that this would contribute to raising standards. This survey of primary schools aimed to establish the extent to which primary schools, with same and mixed age classes, implement different grouping practices including setting, streaming, within class ability and mixed ability groupings for different curriculum subjects. Schools were asked to complete a questionnaire indicating their grouping practices for each subject in each year group. The findings showed that schools predominantly adopted within class ability groupings, either mixed or ability grouped, for most subjects. Ability grouping (within class and setting) was most common in mathematics, followed by English and science. Its implementation increased as pupils progressed through school. The type of setting adopted, same or cross-age, tended to reflect the nature of the class structures within the school.  相似文献

Developing formative assessments for postgraduate students in engineering   总被引:1,自引:0,他引:1  
This paper outlines an approach taken to produce computer-based formative assessments for two modules in a one-year taught MSc programme in Road Management and Engineering. It presents the aims of the assessments, the taxonomy adopted to ensure that the formulation of the questions addressed learning outcomes related to the development of higher order skills and the choice of software used. Further, the students’ qualitative perception of the assessments is presented together with a discussion on key elements that affected the implementation procedure. This included an understanding of the higher order skills assessed, knowledge of the facilities offered by the software to be used, and the commitment needed to designing, delivering and improving flexible learning materials.  相似文献

The vast international literature on the effects of different types of ability grouping on self‐concept and pupils' attitudes towards school has focused on pupils from single year groups. This article aimed to explore year group differences in pupils' self‐concept and attitudes towards school as influenced by ability grouping. The study was cross‐sectional in design and measured attitudes towards school and mathematics, general and school self‐concept and preferences for different kinds of grouping in 234 pupils from years 7 through 10 attending a mixed comprehensive school. The findings indicated that mathematics self‐concept was consistently lower than school and general self‐concept; all aspects of self‐concept increased up to Year 9 and then declined in Year 10, pupils in the higher sets tended to have higher self‐concepts; pupil preferences for setting were greater in the higher year groups, as was the extent to which the top set was perceived to be the best. A substantial proportion of pupils wanted to move set, usually to a higher set. Set placement itself did not appear to have a consistent effect on attitudes towards mathematics. This seemed to be mediated by the quality of teaching.  相似文献

This article examines poor, moderate and good anecdotal episodes in the social context. The research results suggest 1) the quality of anecdotal episodes is discriminated on the basis of energy and clarity concepts rather than the traditional delivery and content perspective, and 2) the energy and clarity of anecdotal episodes are related to observer's perceived social attraction and projected potential to achieve social and professional success. Tnese results suggest that anecdotal episodes merit further consideration in relational development research from the communication perspective.  相似文献
