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
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
Using Schoology in the Era of IR 4.0 (Factors Analysis From Students Perception)
Full text linkThis study aimed to gain students\u27 perceptions in the use of Schoology to assist their learning activities in the era of industrial revolution 4.0. This study involved four classes that applied online and offline learning systems that used Schoology in their lecture activities. This type of research is quantitative description with a factor analysis involving 100 respondents who were given a questionnaire. The instrument of the study was close-ended questionnaire that refer to several indicators such as student technology literacy, student learning styles, lecturer roles, and features of Schoology. Then, the results of this study showed that there were five important factors about the use of Schoology in facilitating their learning activities both inside and outside the classroom
THE EFFECT OF USING FULL-ENGLISH AS LANGUAGE OF INSTRUCTION IN IMPROVING CHILDREN’S SPEAKING SKILL
Full text linkThis research was an attempt to prove the effectiveness of using full-English as a language of instruction in improving children’s English-speaking skill. Treatments were given in 6 meetings for each of the control and experimental class. Two types of lesson plans were arranged, one used full-English as the language of instruction for the experiment class and the other used mixed language (a combination of English and mother tongue) for the control class. An experiment with a quasi-experimental design and an oral test were used as the method and instrument. Based on the calculation of Chi-square and Fisher tests, it was found that the data of both classes were homogeneous and normally distributed. After fulfilling the requirements, the hypothesis was tested by using the T-test at 0.05 significance level. The findings discovered that t-computation was higher than t-table (+3.25 > +1.67). It indicated that the mean of the experiment class was significantly higher than the control class. The findings above led to a conclusion that the use of full-English as language of instruction was effective in improving children’s English-speaking skill. However, since the children were still beginners of English as a foreign language, then it was advisable to ensure that the English used by teachers be inside the children’s zone of proximal development. It was also recommended for teachers to use broken instead of standard English and to accompany their language input with gestures in order deliver meaning easier.
 
The Effect of Instructional Methods in Teaching Speaking to Young Learners
Full text linkThis study searched for empirical evidence of which instructional method, either Presentation-Practice-Production (PPP) or Task-based Learning (TBL), was more effective in teaching speaking to real beginners of young learners. The selected samples were taken by non-random sampling from Foundation II level with ten students for each class. This study, whose data was collected through an oral test, was an experimental research by using T-test at 0.05 significance level. The findings revealed that t-computation was higher than t-table (+2,11 > +2,10). It implied that the mean of PPP class was significantly higher than TBL class. The findings above led to a conclusion that the use of PPP was more effective than TBL in teaching speaking to young learners. It was also discovered that drilling activities, which occurred intensively in PPP, yet not in TBL, gave a great contribution in supporting the effectiveness of PPP in teaching speaking. Drillings were beneficial and met the characteristics of the students who belonged to the population of this study. Therefore, PPP, rather than TBL, was more recommended in teaching speaking to real beginners of young learners whose characteristics met the ones mentioned in the discussion below. However, since drillings can be very mechanical and meaningless, in order not to cause boredom, the length of time allocated for the activities should be considered carefully. Moreover, for an optimum result, drillings must always be accompanied by communicative activities
SPEECH ACT GENDER BASED (STUDY CASE: COMMENTATORS’ RESPONSES OF DONALD TRUMP SPEECH)
Full text linkThis study aimed to describe the forms, attitudes, and typical speech acts of the illocutionary commentators by gender on President Donald Trump's speech at the Liberty University. The method used in this research was descriptive qualitative approach to speech acts. Data sources were obtained from commentators on President Donald Trump's speech. The data used was comments written below the speech video display downloaded on Youtube. The data analysis technique was an interactive analysis consisting of four stages, namely data collection, data reduction, data analysis, and drawing conclusions
