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

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

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

Résumé Il est contre nature d'étudier l'enfant en découpant différents âges ou différents stades. L'enfant est un être qui a son unité longitudinal. Actuellement la psychologie génétique nous permet d'avoir une conception scientifique de l'enfant. Cette conception scientifique définit et précise une conception contemporaine de l'éducation. A la base de cette conception qu'on appelle l'éducation se trouve la confiance dans l'avenier de l'homme et les pouvoirs de l'éducation. Ceci serait insuffisant si nous n'avions pas aussi des idées sur le rôle de l'enfant et de l'homme dans la société. Si nous voulons préparer un enfant à devenir un citoyen capable de jouer son rôle dans la société contemporaine il faut le préparer dès le plus jeune âge à cette tâche importante. C'est la raison pour laquelle nous pensons qu'il est juste de dire que l'enfant est le père de l'homme.
It goes against nature to study the child by arbitrarily establishing different ages or different stages. The child is a human being, who has a longitudinal unity. At the present time, genetic psychology allows us to have a scientific conception of the child. This scientific conception defines and specifies a contemporary conception of education. At the base of this conception that we call education is confidence in the future of man and in the powers of education. This would not be sufficient if we did not also have certain ideas on the role of the child and of man in society. If we wish to prepare a child to become a citizen who is capable of fulfilling his role in contemporary society, we must start at the earliest age to prepare him for this task. That is why we think it is true to say that the child is the father of the man.相似文献

Rolfe (1991) and Parasuraman (1981) are critical of previous efforts by researchers to evaluate simulations given that very few authors in the field of simulation are actually considering validity, reliability or utility of simulations as training or educational methods.
The Rank Ordering Exercise is designed as an activity which highlights evaluation issues. It was explained to 26 participants divided into 13 pairs. Each pair were asked to order 26 cards into a preferred chronological sequence—from the early stages of planning to the final stages of the project. Participants were given a scenario outlining a company which is experiencing complaints about the quality and standard of its customer care. A brief set of instructions asked participants to develop a training programme which incorporates a simulation, with the aim of building in evaluation components.
The Rank Ordering Exercise raised awareness of internal and more importantly external validity issues. The authors noted an overall agreement about a preferred sequence of events and the exercise was effective in highlighting the need for the evaluation "checks" to be made during the planning stages of any research or consultancy project. 相似文献

What influences the regional diversity of reviewers: A study of medical and agricultural/biological sciences journals 
下载免费PDF全文
下载免费PDF全文 There is evidence of a geographical imbalance of reviewers, leading to concerns about the sustainability of peer review to ensure high‐quality, timely publications. This research evaluated articles submitted during 2016 to 149 Wiley‐owned journals in two disciplines: medicine (112 journals), and agricultural and biological sciences (37). We compared the reviewer location with the location of the author and the Editor‐in‐Chief, the size and rank of the journal, and whether the journal had difficulty in obtaining reviews. We found that reviewers mostly came from the USA, but there was a correlation between the reviewer location and the country and region of the Editor‐in‐Chief and that of the corresponding author. Reviewers were also more likely to accept invitations to review articles when the corresponding author was from their region and were more likely to be positive about such articles. We found no difference between journals of different disciplines and of different rank or size or difficulty in obtaining reviews. 相似文献

Scientific knowledge dynamics and relatedness in biotech cities 总被引：4，自引：0，他引：4
This paper investigates the impact of scientific relatedness on knowledge dynamics in biotech at the city level during the period 1989–2008. We assess the extent to which the emergence of new research topics and the disappearance of existing topics in cities are dependent on their degree of scientific relatedness with existing topics in those cities. We make use of the rise and fall of title words in scientific publications in biotech to identify major cognitive developments within the field. We determined the degree of relatedness between 1028 scientific topics in biotech by means of co-occurrence of pairs of topics in journal articles. We combined this relatedness indicator between topics in biotech with the scientific portfolio of cities (i.e. the topics on which they published previously) to determine how cognitively close a potentially new topic (or an existing topic) is to the scientific portfolio of a city. We analyzed knowledge dynamics at the city level by looking at the entry and exit of topics in the scientific portfolio of 276 cities in the world. We found strong and robust evidence that new scientific topics in biotech tend to emerge systematically in cities where scientifically related topics already exist, while existing scientific topics had a higher probability to disappear from a city when these were weakly related to the scientific portfolio of the city. 相似文献

The Influences of Faculty on Undergraduate Student Participation in Research and Creative Activities
Using data collected from surveys of college juniors and seniors and faculty members in related academic departments, this
study examined whether faculty teaching and research orientations, as well as faculty external funding, had any impact on
undergraduate student participation in research and creative activities. The results of the study indicated that faculty research
orientation and external funding were indeed positively related to student participation in research activities. However,
faculty members’ teaching orientation was not significant. Further analyses indicated that faculty teaching and research orientations
had different impacts on a range of research and creative activities by undergraduate students. The findings from this study
provide insight on ways of improving college teaching and learning as well as informing the development of institutional academic
policies related to faculty and undergraduate education.

The study aimed to find whether journal editorial office administrators were as effective as editors at assigning rigorous reviewers. We analysed four journals using blended systems of editor‐selected reviewers (ESR) and Journal Administrator‐selected reviewers (JASR) from four disciplines: medicine, sociology, education, and business/applied psychology. In blended journals, both editors and Journal Administrators select authors to review using web‐based expert‐finding tools. All reviewers selected were both authors and reviewers. We primarily wanted to assess the quality of reviews from both ESR and JASR reviewer selection methodologies. Reviewer rigour was defined as differences between editor decisions and reviewer recommendations. Timeliness data were also recorded and analysed separately as an indicator of efficiency. Reviewer rigour, the quality of reviewers’ evaluations, was estimated from the level of agreement between editors and reviewers. Timeliness was not considered a direct measure of rigour. For two journals, no statistically significant differences were observed; for two, in a small proportion of cases, ESR reviews were more negative. One journal showed some statistically significant major differences but only in 2% of reviews. Timeliness data indicated some statistically significant trends that JASR return reviews more promptly. Therefore, where editors rely on at least two reviewers’ recommendations, JASR is equally rigorous as ESR. 相似文献
