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
A longitudinal investigation of Pakistani university students' motivation for learning English
Get PDFThis study was designed to investigate what factors influence the motivation of engineering university students in province Sindh of Pakistan to learn English. In particular the study attempted to examine the shifting role of integrative motivation in Pakistan by looking at motivational change in these students over the period from the start to the end of the English language course at the university.
To investigate these factors, I adopted a longitudinal quantitative and qualitative approach. The data were collected from the whole cohort of students who enrolled to take the English language course at university (N=541). They completed questionnaires at two points (1) at the start of the English language course and (2) at the end of the English language course. In order to have further illustrative insights some students (N=15) were interviewed at the beginning and at the end of the English language course. The questionnaires and interview tools used in this study attempted to measure students’ responses on 7 motivational factors (1) Instrumental Motivation (2) Integrative Motivation (3) Parental Encouragement (4) English course specific motivational components (5) English Teacher specific motivational components (6) English class and use anxiety and (7) Identity and English learning. The background questions explored students’ views on English learning experiences before coming to the university and students’ perceptions of their English learning at university after English language course.
The results indicate that of the multiple factors that motivate students to learn English, the first among them is integrative motivation to become part of Pakistani community and the Engineering community whose members speak English. The instrumental motivation is for passing exams, raising status in society or to be successful engineer. The perceptions show that parents, grandparents and English teachers play a vital role in this process. The longitudinal nature of the study allowed a picture of motivation that changes with the passage of time to emerge. At the beginning of English language course the students were not confident about their English from their past experience, but were nonetheless motivated to learn English. The students’ attitude to the University English course is positive because they find the tasks in it relevant and interesting. At the end of the English language course the students felt that their confidence had increased and their anxiety had decreased. The background data show that the students come from a range of backgrounds including public and private English and vernacular medium schools and urban and rural areas of Sindh and because of this they have different learning experiences and levels of success with English. At the end of the course, all of them felt positive about learning English in order to become part of the professional community of Engineers, both in Pakistan and internationally.
This suggests that the English language course at University has an equalizing effect and the students’ confidence in the English course and positive expectation to achieve their task of learning English raised their awareness of the progress they were making in learning English
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
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
The Social Media and English Language
Get PDFOMG! LOL! TTYL! ROFL! are the commonly used words in mainstream lately which only proves the astounding popularity of social media these days. There is no doubt in saying that social media has caused a huge effect on English language with words like “Tweet” and “Selfie” making its way down in to English dictionary, it is evident that social media has made quite an impact on English language. Social networks are impulsive and drive us to write faster and with the limit such that of Twitter the limited characters barricade force us to write short which in result lead many in using incorrect abbreviated words and poor grammar. The focus being more on transferring the content, than the container. But on the other hand, it urges a common user to express his/her thoughts in front of a wide and diverse audience. So, there remains a need to further investigate the effects of social media on English language whether it has more positive effects or negative. Keywords: social media, English language, technology, poor grammar, future of Englis
