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
Lecturer Autoethnographies of Adjusting to Online Student Interactions during COVID-19
Get PDFIn 2020, the COVID-19 pandemic pushed South African historically disadvantaged institutions, that had not yet reached advanced levels of technology use in teaching and learning, to find immediate solutions to salvage the disrupted academic year. Interactions with students, which had predominantly been face-to-face, shifted to various online platforms for lecturers to adopt emergency remote teaching approaches. Most of the lecturers were unprepared or incapacitated to make the shift to online environment. Studies have looked at the online teaching and learning experiences of students and lecturers during the COVID-19 pandemic but very few have taken an autoethographic approach to their inquiry and situated experiences in historically disadvantaged institutions. In this article, as lecturers, we use autoethnographies to provide an account of adjusting to interacting with students online during national lockdowns at a historically disadvantaged institution. The Social Cognitive Theory (SCT) was applied to guide the study. This reflexive approach is valuable, as it captures professional encounters and reflections needed to understand the effects of rapid changes to teaching and learning in response to the pandemic. Given the education disparities that already existed between South African higher education institutions before COVID-19, the article contributes to the discourse on how historically disadvantaged institutions can advance higher standards of teaching and learning to serve students better. Our reflections point to the personal, technical and structural challenges of maintaining regular online interaction. Our findings show that different approaches and techniques were applied to adjust to virtual teaching and learning. As teaching and learning methodologies have the potential to ingrain social inequalities, we made recommendations on how to improve online interactions with students from historically disadvantaged contexts
Students’ Responses to Multi-Modal Emergency Remote Learning During COVID-19 in a South African Higher Institution
Get PDFCOVID-19 pandemic forced several higher education institutions (HEI) to operate remotely. Emergency remote teaching, using synchronous and asynchronous instruction, was adopted by several HEIs. The experiences of students with remote teaching and learning in certain situations are not fully understood, thus need to be explored. This study explored the experiences of students with the emergency remote teaching and learning practices adopted at a selected HEI in South Africa. A cross-sectional and self-administered survey was used to gather data from 243 conveniently sampled returning students within the Department of Accounting and Finance. Descriptive statistics were used to make sense of the collected data. The study found that students preferred a face-to-face approach to learning to remote learning. The respondents underscored insufficient data, unstable network connection, unconducive home environments and loneliness as deterrents to effective remote learning. Despite these negative experiences, students appreciated the flexibility and convenience of recorded video lectures and acknowledged the compassion and support of lecturers during remote learning. An understanding of the experiences of students during remote learning provides a basis for future teaching plans, which would improve students' learning experiences. In its current format and students living in their home environments, remote learning greatly diminishes the chances of success for most students. Lecturers need to be compassionate and considerate of student’s struggles in their plans for remote teaching and learning as well as online learning
