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
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
KNOWLEDGE AND HEALTH BELIEFS ABOUT TYPE II DIABETES AMONG COLLEGE STUDENTS USING HEALTH BELIEF MODEL
No full textBackground: Type II diabetes, which is known as non-insulin dependent diabetes, has become an epidemic worldwide. In the United States, diabetes affects 25.8 million people which represent 8.3% of the population. Out of 25.8 million, 23.22 million people have Type II diabetes. According to the National Statistics Vital Report, Type II diabetes was the number seven cause of death in the USA and it can be prevented. The primary purpose of this study was to assess the overall knowledge and health beliefs about Type II diabetes among a sample of undergraduate students; the second purpose was to assess the relationship between the overall knowledge and health belief subscale. Methods: A cross-sectional and descriptive survey design was used. An existing knowledge and health belief instruments was adapted. In the 2014 spring semester, a non- random convenience sample of over 200 undergraduate students who enrolled in Foundation of Human Health 101- class were surveyed in order to assess knowledge and health belief about Type II diabetes. The Health Belief Model provided the theoretical framework for this study. Results: Overview of the participants in this study was provided through conducting a descriptive analysis. Majority of the participant were female, aged between eighteen and twenty, and Caucasian. Data analysis revealed that the overall knowledge about Type II diabetes among participants was low. For the individual health beliefs, perceived susceptibility, perceived severity, and perceived barriers to Type II diabetes were low; however, perceived benefits to engaging in healthy behaviors was high. Having other problems more important than worrying about diet and exercise, and not knowing the appropriate exercise to perform to reduce the risk of developing Type II diabetes were the major barriers among participants. A positive, weak, statistically significant correlation was found between overall knowledge and total belief of benefits to engaging in healthy actions. At the same time, a negative, weak, statistically significant correlation was found between overall knowledge and total belief of barriers to engaging in health lifestyles. Results from multiple regression revealed that knowledge was best predicted by race/ethnicity. Family history, stress level, and level of exercise were the best predictors of perceived susceptibility, perceived benefits, and perceived barriers, respectively. Perceived severity was not predicted by any of the independent variables

No full textThis thesis investigates the genetic characteristics and determinants linked to smoking behaviours and explores the influence of smoking on gene expression in CAD patients. Studying these health-related behaviours can improve the well-being of the Roma minority population. Additionally, the impact of smoking on the blood transcriptome in Hungarian CAD patients remains understudied. These findings would be valuable in strengthening existing epidemiological evidence, identifying relevant determinants, and informing targeted interventions.
This thesis was based on two observational studies. The first was a comprehensive health survey with 814 participants comprising 412 HG and 402 HR. The study compared risk allele frequencies using GRS and wGRS based on data of ten SNPs. HR individuals exhibited significantly higher smoking frequency (33% higher) and tended to start smoking at a younger age (standardized β = -0.23, p <0.001). However, despite the high prevalence of smoking behaviours and nicotine dependence among HR individuals, the study found no significant genetic influence, as median GRS values did not differ significantly, although wGRS was slightly higher among Roma individuals (5.2 vs 4.9; p = 0.02). Additionally, an inverse relationship between SES and smoking behaviours was observed, with smokers showing lower SES (βHR = -0.039, p = 0.023; βHG = -0.010, p = 0.049). The second analysis was based on 61 CAD patients with a median age of 67 years, and only 44 subjects were included for further analyses. Between SM and NSM, 120 DEGs (15 upregulated and 105 downregulated) were identified with a fold change (FC) ≥1.5 and a p-value <0.05. GO analyses revealed that the upregulated genes were related to immune response pathways (FDR≤0.03). In contrast, downregulated genes exhibited significant annotations with pathways involving oxygen and haem binding or activity (FDR≤0.03).
Our first analysis provides evidence of higher smoking frequency and early initiation among HR individuals, but these behaviours are not genetically influenced. The inverse relationship between SES and smoking behaviours highlights the importance of considering socioeconomic factors when studying and addressing smoking habits. On the other hand, the second study offers valuable insights into the potential effects of smoking on gene expression in whole blood and their connection to smoking-related CAD. The previously unexplored overexpression of RCAN3, TRAV4, and JCHAIN genes indicates a possible involvement in CAD among individuals who smoke
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
