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

ABSTRACT
The amino acids tryptophan, tyrosine, and phenylalanine have been extensively used for different label-free protein studies, based on the intensity, lifetime, wavelength and/or polarization of their emitted fluorescence. Like most fluorescent organic molecules, these amino acids also tend to undergo transitions into dark meta-stable states, such as triplet and photo-radical states. While this may be perceived as a problem, these transitions are also highly environment-sensitive and can be used as an additional set of parameters, reflecting interactions, folding states, and immediate environments around the proteins. In this work, we applied the transient state monitoring (TRAST) technique, analyzing the average intensity of tyrosine emission under different excitation modulations, to characterize the photo physics of tyrosine for such readout purposes. By investigating how the dark state transitions of tyrosine varied with excitation intensity and solvent conditions we established a photophysical model for tyrosine. Next, we studied Calmodulin (containing two tyrosines), which upon calcium binding takes a more folded conformation. From these TRAST experiments, performed with 280nm time-modulated excitation, we show that tyrosine dark state transitions clearly change with the calmodulin conformation, and may thus represent a useful source of information for (label-free) analyses of protein conformations and interactions
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
Personifying the social media presence of academic librarians: A uses and gratifications perspective / Niusha Zohoorian-Fooladi
Full text linkDespite the widespread use of social media by students and its increased use in higher education, very little practical evidence is available concerning its prevalence in library services by interpreting academic librarians’ social media presence based on theoretical assumptions. The purpose of this research is to understand academic librarians’ social media presence with respect to their awareness, motivations and current practices using the “uses and gratifications” theory (U&G). The objectives of this study are threefold: a) to examine academic librarians’ usage of social media in Malaysia and the reasons for this behavior, b) to understand the gratifications obtained from creating a social media presence among academic librarians, and c) to model academic librarians’ social media presence in terms of awareness, current practices and motivations. This study uses a qualitative approach that attempts to explore how librarians are using social media based on the theoretical lens of U&G. Case study has been chosen as a research design to holistically explore the web presence of academic librarians and how they use social media in library services. Data was gathered via interviews and three focus groups sessions with 26 academic librarians from three research-intensive universities in Kuala Lumpur, Malaysia. The three research-intensive universities were chosen because they are on their quest to be the regional leader in research and academic excellence and they are among the top universities in Malaysia and in Asia. Participants were from different library departments and were purposively sampled based on the following criteria: a) they sat in the committee of their respective library website, b) they were either heads of departments or librarians in charge of creating content and updating social media applications in the sampled libraries,
iv
c) they considered themselves to be active users in at least one social media tool, and d) they expressed a willingness to take part in the study. The results indicated that at least four types of social medias are deployed in libraries to reach out to the users: blogs, multimedia sharing sites, social bookmarking and social networking sites (SNS). Facebook, Blog, Delicious, YouTube and Twitter are the tools mainly adopted by these libraries. The gratifications for social media adoption in libraries are presented in the form of a honeycomb framework of seven functional building blocks namely: presence, synchronicity, information needs, groups, conversations, relationship and current awareness. Findings reveal that librarians face the following obstacles in creating a social media presence: workflow obstacles, technology obstacles, organizational obstacles and personal obstacles. In order to present librarians’ awareness, practices and readiness towards social media, this study has yielded personas describing four different classes of academic librarians’ social media presence: skaters, sliders, shufflers and starters. These personas represent hypothetical librarians in their work place – introducing them by name, picture and a narrative. It is apparent from the results, that librarians in these three research-intensive universities need support from the library management to mobilize them into a more active and participatory role in creating social media presence
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
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
