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
The effects of diet composition on markers of inflammation in competitively trained cyclists
No full textFor endurance athletes to achieve success, many have adopted a mirage of training programs and nutritional strategies to improve performance; however, considering the risk of elite endurance athletes becoming overreached, it is important to consider the athletes’ immune status, and the effect nutrition can have on inflammation. The purpose of this study is to investigate and compare the effects of a habitual diet (HB), a high-carbohydrate diet (HCD) and a ketogenic diet (KD) on inflammation markers in trained competitive cyclists. This study utilized a randomized crossover trial in six competitively trained cyclists consuming a 2-week diet of the KD and HCD following their HB. Venous blood samples were taken during each diet condition at five time points (0-min, 30-min, 60-min, 120-min, and 180-min) during a resting period. Average concentrations of IL-6, IL-10, IL-8, and TNFα were analyzed using MSD Inflammatory Kit. The findings indicate that following a short period adaptation to the KD resulted in higher concentrations of IL-6 compared to HCD (p = 0.004) and HB (p = 0.004). There was an overall group effect for IL-10 (p = 0.049). Bonferroni-Holm analysis revealed the KD possessed higher levels of IL-10 compared to the HB (p = 0.131) and HCD (p = 0.079). No significant differences in inflammatory markers were observed between the high-carbohydrate diet and habitual diet. Moreover, no significant changes were observed for pro-inflammatory cytokines TNFα and IL-8 across all diet conditions. Cyclists should consider consuming a carbohydrate-rich diet prior to training, to attenuate the risk of suppressing the immune system, leading to an overreached state
The effect of community-based nutrition programs on cancer-related biomarkers in people with cancer
No full textThis study looked at a community-based nutrition intervention in a cancer population. Participants were supplied seven meals a week for the total study duration of 6-weeks. Participants had blood drawn via venipuncture and finger stick. Pre- and post-intervention serum levels of inflammatory cytokines and lipid panel markers. QOL questionnaires assessed participants cancer symptoms, including fatigue, were affecting their physical and social habits. Overall, while no significant changes were seen, the results showed positive trends in self-reported fatigue, health limiting activities, and lipid panel markers. These results can be used as preliminary evidence to support further studies that investigate the use of community-based nutrition interventions for people with cancer. Future research can focus on larger studies that include longer interventions, and look at more specific populations regarding cancer type, sex, or ethnicity
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
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
