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
The Relationship Between Diet, Body Composition, Cardiorespiratory Fitness and Respiratory Quotient
Get PDFBackground: Respiratory Quotient (RQ) indicates the oxidation of fat or carbohydrate as a fuel source for the body during energy expenditure. Resting Metabolic Rate (RMR) and RQ are often determined during the same metabolic test, yet 73% is known of what explains RMR and none is known of what explains RQ. Objective: This thesis aimed to partition the variance in RQ and explore the relationship between determinants thought to explain RQ, such as diet, body composition (fat mass (FM), skeletal muscle, and residual mass), and cardiorespiratory fitness (CRF). Design: This is a retrospective cohort design using data from the Energy Balance Study including 430 participants, healthy men and women between the ages of 21-35. Partitioning of RQ was be measured by conducting a linear regression model. Results: Only 4.8% of the variation in RQ was explained from the linear regression model including models for cardiorespiratory fitness, diet, and body composition. Of this explained variance, majority was explained by percent of total calories from carbohydrate (2.4%, P<0.01). 95.2% variance is still unknown about RQ. Conclusion: This data confirms that percent of total calories from carbohydrate is a significant contributor to RQ. Although the variables of interest in this thesis are not all encompassing, groundwork has been set for future research endeavors to determine RQ’s role in contributing information to personalized healthcare
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
The Relationship between Dietary Intake and Sleep Quality
Get PDFInsufficient sleep is commonly associated with negative health outcomes, and healthy lifestyle recommendations often include suggestions for improving sleep hygiene. Similarly, poor diet habits are associated with a variety of health disorders, and a diet that follows the USDA’s Dietary Guidelines for Americans promotes improved health. This thesis seeks to explore the intersection between sleep and diet and how they relate. To assess the correlation between diet quality and sleep quality, total Healthy Eating Index (HEI-2010) score and sleep efficiency were compared for 422 healthy men and women between the ages of 21 and 35 years from the Energy Balance Study (EBS) (1). Participants were predominantly Caucasian (66.8%) with four of more years of college education (83.7%) and had a mean BMI of 25.3 ± 3.8 kg/m2. Participants spent an average of 7.99 ± 0.94 hours in bed with an average of 6.54 ± 0.89 hours of sleep time. Mean sleep efficiency across the sample was 82.12 ± 7.16 percent. The sample was split into two sleep efficiency groups (85% sleep efficiency group and 0.73 ± 0.81 for the ≥85% sleep efficiency group. No significant difference was found between groups (p = 0.88). The data suggest no relationship between diet quality and sleep quality in participants of the EBS when measured by total HEI-2010 score, whole to refined grain sub-score ratios, and sleep efficiency
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
