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
Grammatical Errors on EFL Students’ Conversation Practice: Surface Strategy Taxonomy
Get PDFThe purpose of this study was to analyze grammatical errors on EFL students’ conversation practice. The participants of this study were the fourth term students of Indonesia Institute of Technology and Business, 2020/2021 academic year. The participants taken as the object of this study because after observation in the students’ class found that there were some mistakes on the students’ speech when doing the conversation in English. The population of this study was from English Training class consisted of four parallel classes Semester IV with the total number of the students was 95 students. Purposive sampling technique was used in this study. This study was conducted by using descriptive qualitative research. The data was words, phrases, and sentences which uttered by the students and writing all non-verbal linguistic that students do on their conversation practice. The data was analyzed based on a classification of errors proposed by Dulay, Burt, and Krashen (1982 in Ellis and Barkhuizen, 2005) called Surface Strategy Taxonomy is applied. The errors in students’ speech were classified by using surface structure taxonomy namely misformation, misorder, addition, and omission. The findings of this study show that omission is the most dominant error produced by participants with the percentage 41.30%. It is followed by misformation with total cases 28.26%, addition with total cases 21.73%, and the last followed by misordering with total cases 8.69%
Utilizing Authentic Materials on Students’ Listening Comprehension: Does it have Any Influence?
Get PDFThe purpose of this study was to investigate the influence of using authentic materials on EFL students’ in listening comprehension. The participants of this study was the second year students of Junior High School in Indonesia, 2014/2015 academic year. The population of this study consisted of five parallel classes with the total number of the students was 190 students. Purposive sampling technique was used in this study. The participants were divided into two groups, the experimental was 38 students and the control group was 38 students. This study used experimental research. The instrument used in collecting data was multiple choice test. The total items of the test was 20 items. The finding shows that t-test (5.09) was higher than t-table (2.02) with the level of significance 0.05 and the degree of freedom (df) = 36. It shows that the hypothesis alternative (ha) was accepted. It means that using authentic materials has influence on students’ achievement in listening comprehension. </jats:p

Get PDFThis research is classroom action research (PTK). This research aims to improve English vocabulary mastery through video media at Bina Jaya Kindergarten to make it even better. The subjects of this research were 13 Bina Jaya Kindergarten children consisting of 8 boys and 5 girls. This research was conducted at Bina Jaya Kindergarten Jl.protokol, Sawit Seberang, Langkat, North Sumatra. The data collection technique is carried out directly and is adapted to the observation format. The instrument used is observation of children in the process of learning to introduce English vocabulary through the use of Youtube video media and documentation. Based on the research results, it shows that with action, there is an increase in the pre-cycle percentage of student's learning achievements reaching 30.76% with the MB criteria. The percentage of children's learning achievement increased in cycle 1 when the percentage reached 69.71%. This percentage increased by 38.95% compared to the percentage in the pre-cycle. An increase also occurred in cycle 2 where the percentage of children's achievements reached 79.81%, an increase of 10.1% compared to the percentage in cycle 1. From the research results, it can be concluded that Youtube video media can improve the ability to master English vocabulary by listening to English vocabulary. , pronounce English vocabulary, mention English vocabulary and write English vocabulary.Penelitian ini merupakan penelitian tindakan kelas (PTK).

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
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
