Do more distant collaborations have more citation impact?   总被引：1，自引：0，他引：1  

Önder Nomaler  Koen Frenken  Gaston Heimeriks 《Journal of Informetrics》2013,7(4):966-971

Internationally co-authored papers are known to have more citation impact than nationally co-authored paper, on average. However, the question of whether there are systematic differences between pairs of collaborating countries in terms of the citation impact of their joint output, has remained unanswered. On the basis of all scientific papers published in 2000 and co-authored by two or more European countries, we show that citation impact increases with the geographical distance between the collaborating counties.  相似文献

Collaborative teaming and critical reflection: A model for practice in preservice programs and general education settings     

Mary Ellen Seery  Joy Kimura Galentine  Patricia A. Prelock 《Journal of Early Childhood Teacher Education》2013,34(1):81-88

Abstract

Inclusion settings for young children with mild to moderate educational needs are becoming the norm. Development of collaborative intervention teams has become essential to effective inclusion. Models of collaborative team development have described multiple aspects of team developmental stages (Tuckman & Jensen, 1977; Lowe & Herranen, 1982). What may be missing in these professional models is the understanding of intrinsic personal qualities that may support or inhibit team development. The model proposed in this reflection advocates a combination of professional and personal commitment models of team development. The authors also explore the benefits of critical reflection about team processes and the value of developing collaborative preservice preparation programs and collaborative intervention models at the preschool and primary levels.  相似文献   

Short-term tracking of performance and health-related physical fitness in girls: The Healthy Growth in Cariri Study     

Simonete Pereira Da Silva  Gaston Beunen  António Prista  José Maia 《Journal of sports sciences》2013,31(1):104-113

Abstract

The main purpose of this study was to track the performance and health-related physical fitness of girls from Brazil's Cariri region. In the “Healthy Growth in Cariri Study”, 294 girls from public and private schools were divided into four age cohorts – 8, 10, 12, and 14 years – and followed for three consecutive years, with an assessment every 6 months. Shuttle run, hand grip, standing long jump, trunk lift, curl-up, 12-min run, and fatness were used to rate physical fitness performance and health-related components on each of six occasions. Tracking was done in a stepwise manner, using auto-correlation, by modelling the individual history of change in performance of each girl, and using Foulkes and Davies’ γ-coefficient. SPSS 18.0 and TIMEPATH were used for data analysis. Auto-correlations evidenced low-to-moderate values in almost all components of performance and health-related physical fitness. Intra-individual tracking analysis showed large variation in all fitness components as a result of a wide spread in individual history of change in fitness performance. Population estimates of γ were low in all tests. Our results show low-to-moderate tracking of physical fitness components of girls. A wide range of intra-individual and inter-variability in fitness development was observed.  相似文献   

Methodological issues associated with longitudinal research: Findings from the Leuven Longitudinal Study on Lifestyle,Fitness and Health (1969 – 2004)

Abstract

Longitudinal studies provide unique opportunities but are also faced with several limitations. The purpose of this study was to document three of these issues (“imperfect” design, evolution of data collection methods, representativeness) by means of the Leuven Longitudinal Study on Lifestyle, Fitness and Health (LLSLFH). The LLSLFH (1969 – 2004) comprises observations on males between 12 and 18 years and at 30, 35, 40, and 47 years, and on females at 16 and 40 years. In the most recent phase of the study, spouses and offspring were also included. The different phases and evolving research questions throughout the LLSLFH required an appropriate adaptation of the research design. The associated evolution of data collection methods largely reflects the changing ideas about physical fitness, body composition, and physical activity, the continuing search for new and better measurement techniques, and the need for adaptations with age. Ongoing study participants are representative in terms of body composition and, except for adolescence in males, also physical activity. No straightforward answer can be given concerning physical fitness. In both sexes, socio-economic status is above average. When informed about the possible “pitfalls” of longitudinal research in advance, several measures could be taken to prevent or limit them as much as possible.  相似文献   

Supporting mathematics vocabulary instruction through mathematics curricula     

Erica M. Barnes  S. Joy Stephens 《Curriculum Journal》2013,24(3):322-341

Abstract

This study examines four of the most commonly-used core mathematics curricula in the USA for evidence of support for research-based instructional strategies for mathematics vocabulary in first and second grade. Content analyses of the teachers’ editions of two units for each grade level were analyzed per curriculum (n?=?16). Statistically significant differences among curricula were found for number of target words (range 6–51 per unit), level of difficulty of terms (basic to technical), and number of support strategies per word. Multiple means of representation varied in terms of verbal and non-verbal strategies for target terms. These differences indicate children are experiencing substantially different mathematics vocabulary learning opportunities, which may impact later mathematics achievement. Implications for practice, curriculum development, and future research are addressed.  相似文献   

The impact of federal financial aid policy upon higher education access     

Dannielle Joy Davis  Lisa Celeste Green-Derry  Brandon Jones 《Journal of educational administration and history》2013,45(1):49-57

This article reviews the history of financial aid policy from the Higher Education Act of 1965 to its reauthorisation in 1992 and the subsequent ramifications upon African-American students. It considers issues of race and class with regard to college access. This work concludes with a look at contemporary aid, as well as offers race- and class-conscious financial aid by increasing college affordability to low-income students, as potential solutions to broadening educational access to Black Americans.  相似文献   

Supporting self-evaluation in local government via Knowledge Discovery and Data mining     

Hye-Chung Kum  Dean F. Duncan  C. Joy Stewart 《Government Information Quarterly》2009

The business sector has already recognized the importance of information flow for good management, with many businesses adopting new technology in data mining and data warehousing for intelligent operation based on free flow of information. Free flow of information in government agencies is just as important. For example, in child welfare, entities that fund social services programs have increasingly demanded improved outcomes for clients in return for continued financial support. To this end, most child welfare agencies are paying more attention to the outcomes of children in their care. In North Carolina, many county departments of social services have successfully adopted the self-evaluation model to monitor the effects of their programs on the outcomes of children. Such efforts in self-evaluation require good information flow from state division of social services to county departments of social services. In this paper, we propose a comprehensive KDD (Knowledge Discovery and Data mining) information system that could upgrade information flow in government agencies. We present the key elements of the information system and demonstrate how such a system could be successfully implemented via a case study in North Carolina. The next generation infrastructure in digital government must incorporate such information system to enable effective information flow in government agencies without compromising individual privacy.  相似文献

Significant Influences on the Development of Adults’ Environmental Awareness in the UK,Slovenia and Greece     

Joy A. Palmer  Jennifer Suggate  Barbara Bajd  Elissavet Tsaliki 《Environmental Education Research》1998,4(4):429-444

This article provides an overview and discussion of the relative importance of various categories of significant influences and formative life experiences on the development of environmental educators’ knowledge of and concern for the environment. A previous article in this journal (Palmer & Suggate, 1996) presents relevant findings deriving from the UK and analyses the ways in which the importance of influences may change through time or be affected by the subject's age. Here, the team of international authors presents data from three European countries and engages in both location‐specific and cross‐cultural comparative analysis.  相似文献
