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
Team Teaching as a Panacea to Students’ Low Academic Achievement in Chemistry in Rivers State, Nigeria
Get PDFCollaboration is a useful process of creativity. Hence, the main purpose of this study is to investigate team teaching as a panacea to students’ low academic achievement in Chemistry. Quasi experimental research design was adopted for the study and purposive sampling techniques was used to select Emohua Local Government Area in Rivers State, Nigeria. Simple random sampling by balloting was carried out in two rounds to select two schools and a sample size of (100) SS2 Chemistry students that participated in the study. Chemistry Achievement Test (CAT) was used to collect data for the study. The data collected was analysed using mean and standard deviation to answer all the research questions while Analysis of Covariance (ANCOVA) was used to test the hypotheses at .05 level of significance. The study found that, there was significant difference between the mean score of students exposed to team teaching and those exposed to lecture method in favour of those exposed to team teaching in Chemistry. Gender had no significant effect on mean scores of students exposed to both lecture method and team teaching method in Chemistry. This study recommends the use of team teaching method for Chemistry teachers and equal opportunities for students irrespective of gender
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
EFFECT OF USING CONCEPT MAPPING STRATEGY FOR HYDROCARBONS LESSONS ON STUDENTS’ ACADEMIC ACHIEVEMENT IN CHEMISTRY
No full textThis study investigated the effect of the concept mapping strategy in the teaching of hydrocarbons lessons on students’ academic achievement in chemistry. Quasi experimental research design was adopted and purposive sampling technique was used to select Obio/Akpor Local Government Area out of the twenty three (23) local government areas in Rivers State. Simple random sampling by balloting was used to obtain two (2) senior secondary schools. A second round of simple random sampling was used to obtain a sample size of one hundred and twenty (120) SS2 Chemistry student comprising 50 males and 70 females that participated in the study. Chemistry Achievement Test (CAT) was used for data collection. The data collected were analysed by using mean and standard deviation to answer all the research questions while Analysis of Covariance (ANCOVA) was used to test the hypotheses at .05 level of significance. The study found that, there is significant difference between the mean achievement scores of students exposed to hydrocarbons lessons by using concept mapping and lecture methods, P<.05. Gender do not have significant effect on students exposed to both concept mapping and lecture methods in chemistry, P>.05. the study recommends that, chemistry teachers should often use concept mapping strategy in their classrooms as it is gender friendly and can boost academic achievement of students in chemistry
