The majority of physical activity initiatives have been directed toward promoting cardiorespiratory fitness and general health. Far less attention has been devoted to encouraging or understanding muscular fitness-promoting behaviors. The purpose of this study was to determine if constructs from the Transtheoretical Model, a contemporary behavior change framework, could be adapted and applied to the study of muscular fitness-promoting behaviors. Participants were 429 college students who completed measures of stage of change, the behavioral and cognitive processes of change, and self-efficacy. All measures were modified to relate specifically to muscular fitness-promoting behaviors. Two direct discriminant function analyses were performed, revealing that the behavioral processes of change and self-efficacy were the major correlates of the stages of change for muscular fitness-promoting behaviors. 相似文献

OBJECTIVES: The authors sought to find out whether certain Webometric indexes of a sample of pediatric Web resources, and some tests based on them, could be helpful predictors of their disappearance. METHODS: The authors performed a retrospective study of a sample of 363 pediatric Websites and pages they had followed for 4 years. Main measurements included: number of resources that disappeared, number of inbound links and their annual increment, average daily visits to the resources in the sample, sample compliance with the quality criteria of 3 international organizations, and online time of the Web resources. RESULTS: On average, 11% of the sample disappeared annually. However, 13% of these were available again at the end of follow up. Disappearing and surviving Websites did not show differences in the variables studied. However, surviving Web pages had a higher number of inbound links and higher annual increment in inbound links. Similarly, Web pages that survived showed higher compliance with recognized sets of quality criteria than those that disappeared. A subset of 14 quality criteria whose compliance accounted for 90% of the probability of online permanence was identified. Finally, a progressive increment of inbound links was found to be a marker of good prognosis, showing high specificity and positive predictive value (88% and 94%, respectively). CONCLUSIONS: The number of inbound links and annual increment of inbound links could be useful markers of the permanence probability for pediatric Web pages. Strategies that assure the Web editors' awareness of their Web resources' popularity could stimulate them to improve the quality of their Websites. 相似文献

The objective was to gain an overview of researchers experiences of searching the literature, with particular reference to the use of optimal search strategies (OSSs) and searching for qualitative research studies. A 13-item semi-structured questionnaire investigating search behaviour was distributed to members of the Cochrane Qualitative Methods Network. Follow-up interviews were conducted with a subset of respondents to explore issues raised and clarify points of ambiguity. Findings were analysed using data reduction, data displays and verification techniques. Eighty-six per cent of distributed questionnaires were returned. All respondents reported searching electronic databases as part of their literature search, with 80% expressing a preference for searching alone or with colleagues. Forty-one per cent indicated that they consider a database search to be only one aspect of a comprehensive literature search. The rigour and availability of OSSs was a concern for 30% of respondents. Twenty-five per cent of respondents had searched for qualitative studies, although the difficulty of locating this type of literature was considered problematic because of the varied use of the term 'qualitative'. Whilst the majority of respondents reported using OSSs in some capacity, reservations were expressed about their ability to facilitate a comprehensive search. Replies indicated a belief that OSSs can reduce the sensitivity of a search, and might limit the breadth of coverage required. A greater appreciation of the availability and purpose of OSSs-including the ability to optimize either sensitivity or recall-is needed if this enhanced approach to accurate data retrieval and potential improvement in time management is to become widespread. 相似文献

We studied the emergence of biotechnology in Turku, Finland. First, we analysed it as a result of the interaction between the city and its national and international environment, focusing on the city’s industrial policy as the mediator. Second, we diagnosed the construction of BioCity, the first biotechnology centre building of Turku, as a key event: the conceptualisation and construction of BioCity required a new kind of collaboration between the city administration, the universities and various commercial actors. We argue that the systems approach to regional development needs to be complemented with approaches that focus on the regional mechanisms of adaptation. 相似文献

Scientific reasoning is particularly pertinent to science education since it is closely related to the content and methodologies of science and contributes to scientific literacy. Much of the research in science education investigates the appropriate framework and teaching methods and tools needed to promote students’ ability to reason and evaluate in a scientific way. This paper aims (a) to contribute to an extended understanding of the nature and pedagogical importance of model-based reasoning and (b) to exemplify how using computer simulations can support students’ model-based reasoning. We provide first a background for both scientific reasoning and computer simulations, based on the relevant philosophical views and the related educational discussion. This background suggests that the model-based framework provides an epistemologically valid and pedagogically appropriate basis for teaching scientific reasoning and for helping students develop sounder reasoning and decision-taking abilities and explains how using computer simulations can foster these abilities. We then provide some examples illustrating the use of computer simulations to support model-based reasoning and evaluation activities in the classroom. The examples reflect the procedure and criteria for evaluating models in science and demonstrate the educational advantages of their application in classroom reasoning activities. 相似文献

The aim of this study was to analyse the relationship among emotional intelligence (EI) and learning strategies, identifying different emotional intelligence profiles and determining possible statistically significant differences in learning strategies through the identified profiles. Thousand and seventy one Spaniards secondary school students aged 14–17 participated in the study, completing the Trait Meta-Mood Scale-24 (TMMS-24) and the Cuestionario de Estrategias de Aprendizaje [Learning Strategies Questionnaire] (LSQ). Cluster analysis identified four differentiated EI profiles: a group of adolescents with a low EI profile, a group with high scores in attention and low scores in repair, a high EI profile group, and a group of adolescents with predominance of low attention and high repair. The results also revealed statistically significant differences among the profiles in most of the learning strategies, in which students with high general EI and those with predominance of low attention and high repair use more learning strategies than the other groups, suggesting the importance of developing programmes of emotional skills to study in greater depth EI and its influence on students’ learning strategies. 相似文献

Gender policies in sports have expanded considerably in most countries in recent decades. Nevertheless, the implementation of these policies in sports organizations is by no means an automatic process. This article explores what happens when gender equity policies are applied in an university sports organization. Participatory action research over a four-year period was developed by the authors to increase the participation of women, and it also aimed to explore the perceptions and thoughts of key actors regarding equity actions. The analysis shows the participation numbers in the specific promotional campaign and reveals a wide range of responses among staff, ranging from enthusiasm and interest to resistance and fear. Gender equity actions often encounter resistance which cannot, and should not, be ignored. This article highlights certain forms of resistance that proposals of this kind should be prepared for. 相似文献

In this study, 123 children with a diagnosis of developmental dyslexia were assigned to different treatment groups, either variations of Bakker's intervention program based on the balance model or a control, a specific reading training group. Thorough cognitive and neuropsychological assessment allowed determination of the subtype of dyslexia according to the balance model and the neuropsychological profile with respect to reading and spelling abilities, verbal memory, and phonemic awareness. Characteristics of hemisphere-specific stimulation were systematically manipulated in an effort to shed light on the bases and mechanisms of reading improvement. It was shown that the effects of treatment vary according to type of dyslexia and that the different intervention programs have differential effects on reading-related neuropsychological functions. Since opposite effects can be produced by the same type of treatment in different dyslexia subtypes, the results of the study suggest that accurate classification of subtype on the base of reading and reading-related variables is advantageous for an optimal planning of the therapy. 相似文献
