Patterns of Bureaucracy in Intercollegiate Athletic Departments
No full textThe objective of the current research was to verify the extent to which Gouldner’s (1954) three patterns of bureaucracy were prevalent in intercollegiate athletic departments. Single and multiple-group confirmatory factor analysis (CFA) and structural equation modeling (SEM) of the data provided by 907 coaches from all three NCAA divisions (ndivI= 322; ndivII= 277; ndivIII= 308) showed that structural relationships among goals, processes, and patterns of bureaucracy were invariant among all three groups of coaches. Substantively, the factor of developmental goals through developmental processes (Trail & Chelladurai, 2000) predicted positively the presence ofrepresentative bureaucracyandpunishment-centered bureaucracyand negatively the existence ofmock bureaucracy. This means that the more athletic departments emphasize academic values, the less the coaches perceive a pattern of loose coupling between rules and actual technical activities. Implications of these results for theory and practice were discussed

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Growth of GaN-based LED on C-plane GaN substrate / Sivanathan Pariasamy @ Chelladurai
No full textThe InGaN/GaN multi-quantum wells, growth on bulk GaN substrate were studied for
blue light emission via metal-organic chemical vapor deposition (MOCVD). The homoepitaxy
growth of GaN-on-GaN gives an unprecedented high performance with low defect
density, high-quality crystal, simplified LED architectures (short process flow) and overall
lower cost. The optimizations of InGaN/GaN MQWs on n-type GaN substrate for blue
emission at 445-455 nm range were carried out. The high quality 6 pairs of multi-quantum
wells with InGaN quantum wells and GaN quantum barriers were grown at different
temperatures (650�to 780�). The lowest defect density demonstrated at 1.3�107 c
