This paper analyses the publication patterns of researchers in the field of applied sciences at Universities of Technology in South Africa. Aspects investigated include publications in SCOPUS-listed journals; number of citations and countries of publication. Collaborative research patterns at national and international levels were also investigated. A bibliometric analysis approach was followed using SCOPUS as the main source of data and analysing the articles published in selected applied science disciplines. Results show that researchers in the field of applied sciences in universities of technology have increased their number of publications over the past 10?years and are also working in conjunction with other researchers both nationally and internationally. The analysis is an important addition to the field in South Africa which helps in measuring how institutions are positively responding to government incentives in research. The results are also important to information professionals who are increasingly playing an important role in research impact assessments.  相似文献

A study was conducted to assess the validity of the Global Physical Activity Questionnaire (GPAQ) for measuring sedentary behaviour (SB) in the Chilean adult population. About 217 adults (93/124 male/female, 43.8 ± 15.75 years) who were randomly selected during National Health Survey 2009–2010 completed the protocol. The participants wore an ActiGraph GT3X (AG) for 7 consecutive days and then completed the GPAQ (single-item question for measuring time spent sitting in a usual day). Validity was examined using Spearman’s correlation, mean bias and limits of agreement (LoA), with AG (vertical axis <100 counts · min?1) as the reference standard for estimates of SB in bouts of 1 (AG1), 5 (AG5) and 10 (AG10) min. Agreement between the GPAQ and AG for classifying data into quartiles and tertiles was assessed with kappa method. The GPAQ showed fair correlation with AG1, AG5 and AG10 (range = 0.23–0.26), with large mean biases (range = ?293.9, ?76.12 min · day?1). Agreement between the GPAQ and AG1, AG5 and AG10 was poor for categorising time spent in SB into tertiles and quartiles. The single question from the GPAQ has shown fair validity for measuring SB and poor ability for correctly classifying individuals into tertiles or quartiles of SB in a Chilean population.  相似文献

This study examined the contribution of situational probability information to the perceptual and cognitive processes underlying decision-making behaviour during in situ Karate performance. Experts and novices were required to make decisions about various attacks in different fight scenarios. The order in which the fight situations were presented was modified in order to provide advanced probability information and identify whether fighters were able to use the latter information to make better decisions. Specifically, one of the attacks was repeated every four actions. Results revealed that experts were more accurate and faster than their less skilled counterparts to block and counterattack the opponent. The experts picked up the occurrence of the attack pattern after the fifth repetition whereas novices did not. This enabled experts to improve decision time and decision accuracy. Findings suggest that such superiority could stem from the perceptual and cognitive skills possessed by the experts, thus giving them the opportunity to recognise a situation more easily. This was reinforced by gaze behaviour which demonstrated that experts used a more efficient search strategy involving fewer fixations of longer duration on a lesser number of areas relative to the novices. Moreover, experts generated more refined karate-specific knowledge structures compared with the novices.  相似文献

数学教学中的开放式教学——创造一种课堂数学文化   总被引:5,自引:4,他引:5  
数学教学中需要对开放式教学进行合作研究。在日本的开放式教学中,数学问题被选择是用来说明一个问题的多种解法或多个正确答案。数学教学要实现一种全新的课堂数学文化,这种数学形式的特点是:问题开放、解决问题的过程开放、构建问题开放、评价开放,使学生能自由地思考,发展学生的思维能力。  相似文献

Objective: To analyze the association between attitudes of filial responsibility and adult child caregivers’ behaviors in the Southern Region of Brazil.

Methods: Cross-sectional study with 100 child caregivers of older adults. The data were collected through an interview using the protocol of filial responsibility adapted and validated to Brazilian Portuguese. Filial Expectation and Filial Piety scales evaluated the attitudes of filial responsibility. Caring behaviors assessed were: instrumental support, emotional, financial support, and companionship. The variables that presented p< .20 value in the bivariate analysis were inserted into a multivariate Poisson regression model.

Results: Financial and emotional support behaviors were significantly associated with filial piety (p = .050 and p = .001, respectively) and filial expectation (p = .013 and p = .023, respectively). Providing companionship was associated with filial piety (p = .015).

Conclusion: Attitudes of filial responsibility are associated with some but not all caregiving behaviors. Brazilians caring for older parents show more similarities to Chinese than to Canadian caregivers. Furthermore, filial responsibility and caregiving behaviors are strongly affected by Brazilian social and cultural norms. Reasons are discussed.  相似文献

Processus de preuve et situations de validation   总被引:2,自引:0,他引:2  
Résumé Nous étudions les relations entre preuves et contradictions dans la résolution d'un probleme de mathématiques. Cette étude montre la nécessité d'une approche à la fois situationnelle et cognitive, notamment en référence au fonctionnement des connaissances dans l'apprentissage des mathématiques. Ceci nous conduit à distinguer différents stades dans l'évolution des preuves pragmatiques aux preuves intellectuelles. Enfin nous montrons que le dépassement d'une contradiction ne constitue pas nécessairement un progrés cognitif, en particulier nous examinons le traitement d'un contre-exemple par des élèves de quatrième.
Proving processes and situations for validation
A study is made of the relationship between Proofs and Contradictions in mathematics problem-solving. With respect to mathematics learning, we show the necessity for an approach being both situational and cognitive. This study leads to the demarcation of several stages from Pragmatic Proofs to Intellectual Proofs. We then go on to show that overcoming a contradiction does not necessarily constitute cognitive progress. In particular we examine how pupils (13–14 year old) cope with counterexamples.

The link between social capital (SC) and Facebook has been widely studied in the U.S., and less is known about how students from different cultures use the site to garner SC. We measured network composition, communication on Facebook, and SC via questionnaires in France and the U.S. We found that American students have a greater proportion of distant to close ties in their networks and higher levels of bridging SC than French, the latter preferring bonding SC. A stronger relationship between SC and communication via Facebook was observed in the U.S. These findings are explained by cultural differences in relatedness.  相似文献
