Association of dietary fiber intake with metabolic risk factors for type 2 diabetes in African American men.
No full textAn insufficient amount of research has focused on the relationship between dietary intake and type 2 diabetes among African Americans (AA) which are disproportionately affected by the disease. This study examined the association of dietary fiber intake on metabolic risk factors for type 2 diabetes in AA men with a family history of type 2 diabetes. Measurements of anthropometry, blood pressure, DXA, and blood lipid profiles from the ARTIIS study (parent study) were used in the current study. Also, food frequency questionnaire and lifestyle history questionnaire were used. Outcomes indicated that dietary fiber intake is far below recommendations in AA men. Subjects that consumed higher dietary fiber had lower LDL-C (P≤0.05) and they self-reported currently exercising (P≤0.05). The relationship between dietary fiber and metabolic risk factors for type 2 diabetes was not evident. Our findings indicate the imperative need to further examine dietary patterns within AA and their influence on metabolic outcomes
Assessing dietary behavior changes in African Americans using the Veggie Meter and 24-hour dietary recall.
No full textIncreasing fruit and vegetable (F&V) intake is key goal for populations at risk for type 2 diabetes mellitus (T2DM). Many researchers assess F&V intake through traditional dietary assessment such as 24-hour dietary recalls, which can be prone to response bias. This study involved the Veggie Meter®, a non-invasive method of assessing skin carotenoid scores, to provide an objective measure of dietary intake coupled with traditional dietary recalls. Following a 6-week culturally-tailored healthy-eating program with a 6-week follow-up, dietary intake of carotenoids lutein and zeaxanthin was marginally significant (p=0.054), while no significant changes were detected in other carotenoids or VM scores. However, intake of vitamin D (p=0.039), total vegetables (p=0.016), and total starchy vegetables (p=0.018) significantly increased. These findings suggest the potential for culturally tailored dietary interventions to improve vegetable intake in African American adults at risk for T2DM, although further research is needed to expand on these results
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
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
