Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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

The impact of computers on teachers : a general computer attitude study of some teachers in Singapore
No full textUnder the Singapore Information Technology (IT) Masterplan, the Ministry of Education has scheduled a series of compulsory IT training for teachers with the purpose of equipping them with the necessary computer skills and knowledge so that they will be able to integrate IT into their classroom teaching. Schools are equipped with overwhelming number of computer hardware and software, ready to be used by teachers and pupils. This study takes advantage of this current setup to look into the general computer attitude of practicing teachers in Singapore. A survey questionnaire consisting of 20 items adapted from existing computer attitude scales was administered to 173 teachers in three different school levels. Four dimensions were chosen: computer anxiety, computer in-attitude toward learning and using computers, computer in-confidence and computer future in-perception (in-vision). The general computer attitude of teachers in Singapore was found to be positive. There were no gender differences found. Some older teachers were found to be more anxious than some younger ones. Teachers with prior computer experience were more positive toward computers. Computer ownership complemented the availability of computers in school in ensuring accessibility to the technology which provided for the necessary amount of exposure to teachers. On the other hand, teachers with some computer training were less positive than those with no training and those who were fully trained in using computers. All teachers perceived that computers would dominate the school in the future and that there was a need to acquire computer skills in order to stay relevant in the profession.Master of Educatio
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
A comparison between the learning styles of high achieving and low achieving pupils in a primary school
No full textThis study examines the learning style preferences of 126 lower primary students, 63 high achievers and 63 low achievers, in a neighbourhood school. It attempts to identify their learning styles and investigate whether significant differences exist between the learning styles of the two groups of students.
A questionnaire inventory modified from the Learning Style Inventory: Primary (1991) by Janet Perrin was used to identify their learning style preferences.
The findings from this study suggest that high achievers and low achievers have similar learning style preferences. They like learning in a quiet, bright, and formally designed environment. They see themselves as responsible, persistent and self motivated learners. They disliked learning with adults. They prefer their learning to be minimally structured and dislike learning in the evenings.
It also suggests that learning styles discriminate between the two groups of learners. Overall, 8 out of the 18 elements were significantly different. They are temperature, learning with an adult, visual, auditory, tactual perceptual strengths, intake, mobility and time of the day.Master of Arts (Applied Psychology
