Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The influence of an educational dance program on female adolescent self esteem, body image and physical fitness
No full textMaster of EducationIt is generally accepted by proponents of dance in education that dance has many positive effects, both physical and psychological. However, there is little empirical research to support these claims.
The purpose of this study was to evaluate the influence of an educational dance program on self esteem, body image and selected aspects of health-related fitness in a group of adolescent females. The dance program was developed and presented within a school setting and included the components of skill development, composition and performance. This treatment program was compared with physical education, another intrinsically physical activity.
A multiple measurement approach, incorporating both quantitative measures and qualitative observations, was used to assess the impact of dance education. Fifteen female students enrolled in dance were tested prior to and during the concluding weeks of a 10-month dance program. Fifteen physical education students were tested at the same times. Quantitative measures included a self-report self esteem inventory, a behavioural self esteem inventory, a body image scale and physiological assessment of aerobic fitness, skinfold measures and flexibility. Qualitative procedures included weekly observations of self esteem behaviour and preferred movement preferences in dance.
Quantitative analysis using Analysis of Covariance showed a significant difference in favour of dance on post-test measures of self esteem, body image, flexibility and skinfold measures. Pre-test scores were used as covariates in each case. As a result of this experimental study, there is now further statistical evidence that dance may be a valid educational tool. Analysis of qualitative data indicated that dance was a positive learning experience for students and that there may be an observable connection between expressive movement behaviour and self esteem
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
‘If they can say it they can do it’: redesigning pedagogies in senior secondary physical education
No full textPedagogical practices are central to teachers’ work, and in the spaces of schooling bear a potential to impact on students. This impact is particularly significant for students attending schools where low socio-economic factors prevail, as these students rely heavily on formal schooling for their educational resources. Interrelationships between pedagogical practices, senior-secondary physical education curriculum, and the learning experienced by students from a school located in an area of socio-economic disadvantage are explored in this paper. The specific focus is action research conducted by a physical education teacher and university academics, which investigated pedagogical redesign for a ‘skill acquisition unit’. Of key interest are pedagogical practices that sought to scaffold the acquisition and application of scientific literacies, which are fundamental to academic success in senior secondary physical education. Findings reveal high levels of student engagement, successful utilisation of scientific literacies specific to motor-skill acquisition and application of new learning to life-world situations. We argue that pedagogical practices that breach the divide between student life-world knowledge and powerful or specialised knowledge can disrupt default modes of teaching theoretical concepts in physical education, which marginalise and exclude students from low-socio-economic backgrounds.
