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
Visible minority experience in the Canadian advertising industry: A case study of the racialized minority creative worker
Get PDFIssues of race and representation have gained significant consideration in relation to the creative industries and the structures of power within them. This study examines barriers to entry for racial minority creative workers in the Canadian advertising industry. As racial minorities attempt to enter an atmosphere entrenched in white privilege and power, they are met with an interconnected web of struggles that restrict them from entering spaces of influence in advertising. Drawing on concepts of cultural gatekeeping, racial valuation, shallow diversity, and self-monitoring, data from thirteen qualitative interviews have been analyzed through a narrative approach. Influenced by aspects of critical race theory, the lived experiences of participants inform this analysis and provide a new perspective on the preestablished structures of racial inequity. The findings of this study indicate that racial minority workers face an exponentially different experience than their white counterparts throughout their careers. They are forced to appease their white leadership and configure to the demands of the industry that are rooted within white ideals. The performativity of diversity additionally pushes minorities to be extremely cautious of their behaviour and demonstrate greater professional performance than their white counterparts. Due to racial perceptions of majority groups, people of colour must engage in the identity work of code-switching to assemble a balanced character of colour and whiteness. Ultimately, the systemic organizations of power are reproduced through inequitable practices that regulate the progression of racial minority workers in the Canadian advertising industry. This assists in sustaining the ideologies, values, and culture of majority groups within the advertising industry and the cultural products they produce
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
Improving the Bioavailability of Curcumin: A New Formulation
No full textMesolimbic dopamine (DA), particularly in the nucleus accumbens, is involved in regulating behavioral activation and effort-related processes. Interference with DA transmission can lead to the production of symptoms such as anergia, psychomotor slowing, and fatigue that are seen in depression and other related disorders. Considerable evidence indicates that interference with accumbens DA effects response allocation in effort related choice procedures, biasing animals towards the lower effort alternative. Previous studies have shown that administration of the vesicular monoamine transporter-2 (VMAT-2) inhibitor tetrabenazine (TBZ) effects response allocation in the FR5/choice procedure causing a decrease in lever pressing and a compensatory increase in chow consumption. The present studies investigated the ability of curcumin to reverse the TBZ-induced shifts in effort-related choice behavior. Curcumin is a natural dietary metabolite, found in turmeric, which has been successfully used in antidepressant screening paradigms. Additionally, human clinical trials have shown the efficacy of curcumin as an adjunct medication. Curcumin modulates levels of neurotransmitters, such as DA, serotonin (5-HT), and to a lesser extent norepinephrine (NE), by acting as an MAO-A/B inhibitor. Curcumin has low bioavailability. The purpose of the current feeding study was to mimic human administration (i.e., tablets) in rodents by studying the ability of rats to ingest food pellets formulated with curcumin. In these studies, different formulations that included the excipient neusilin were offered to rats. Additionally, the present study was to determine if curcumin that was orally administered by ingestion could reverse the effort-related effects of TBZ
