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
Relationship between mathematics statistics engagement and attitudes towards statistics among undergraduate students in Malaysia
Full text linkThis paper explored the relationship between the attitudes toward statistics and mathematics statistics engagement among undergraduate students taking the statistic course. A total of 293 undergraduate students from several programs at Universiti Putra Malaysia (UPM) were the sample of the study. A structured, self-administered questionnaire was used to elicit responses from these students. Descriptive analyses showed the overall mean for students’ mathematics statistics engagement was 3.38 (SD = .36). The analysis on mathematics statistics engagement domains revealed behavioural engagement had the highest mean (M = 3.63, SD = .52), followed by affective engagement (M = 3.35, SD = .41) and cognitive engagement (M = 3.26, SD = .35). Inferential analysis indicated attitudes towards statistic were positively related to mathematics statistics engagement (p = .721**, p = .001). Further analysis on mathematics statistics engagement domain indicated attitudes towards statistics were positively related to the affective domain (p = .902**, p < 0.001), cognitive domain (p = .818**, p < 0.001) and behavioral domain (p = .855**, p < 0.001). These findings show attitudes are important for students to be engaged in mathematics statistics. Implications of the findings are discussed
Professor Dharam Vir Chopra
No full textThe Department of Mathematics, Statistics and Physics and son Sandeep Chopra celebrated the life of professor Dharam Vir Chopra on Dec. 3, 2021 at Jabara Hall (Room 128).It is with great sadness to announce that Professor Dharam Vir Chopra of the department of Mathematics, Statistics, and Physics passed away Monday, September 14, 2020.
Although he was 89 years old, he was still active in research in Combinatorics and Statistics up to the present. He began a phased retirement in January 2020 after being a faculty member at Wichita State University for fifty-three years. Professor Chopra joined the mathematics department faculty in 1967 as an Assistant Professor. He became an Associate Professor in 1971 and a Professor in 1977. He was instrumental in developing the academic area of Statistics at WSU to the level of becoming a joint department with Mathematics.
Professor Chopra was the Interim Chair of Mathematics in 1982-1983, the Chair of the Department of Mathematics and Statistics in 1985-1987, and the Associate Chair and Director of Statistics at the New Jersey Institute of Technology while on leave from WSU in 1988. Also, he served as Interim Chair of the Department of Computer Science in 1992-1993. While Chair of Mathematics and Statistics, the department began its PhD Program in Applied Mathematics. Professor Chopra served on many LAS and University committees over the years. He was active in research and authored more than 80 papers in scientific journals as well as organizing conferences and holding administrative positions in scientific societies.
Professor Chopra was an accomplished and dedicated statistician who has provided many years of distinguished service to the department and the university. He was well-liked by students and faculty. We shall miss him greatly
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
Some identities involving multiplicative semiderivations on ideals
No full textLet R be a prime ring and I be a nonzero ideal of R. A mapping d : R → R is called a
multiplicative semiderivation if there exists a function g : R → R such that (i) d(xy) =
d(x)g(y)+xd(y) = d(x)y +g(x)d(y) and (ii) d(g(x)) = g(d(x)) hold for all x, y ∈ R. In the
present paper, we shall prove that [x, d(x)] = 0, for all x ∈ I if any of the followings holds:
i) d(xy) ± xy ∈ Z, ii) d(xy) ± yx ∈ Z, iii) d(x)d(y) ± xy ∈ Z, iv) d(xy) ± d(x)d(y) ∈ Z,
viii) d(xy) ± d(y)d(x) ∈ Z, for all x, y ∈ I. Also, we show that R must be commutative if
d(I) ⊆ Z
