Age Bias in Physicians\u27 Recommendation for Physical Activity, Adherence, and Health Related Quality of Life Among Individuals with Arthritis
Get PDFThe association between individuals\u27 ages, physicians\u27 recommendations for physical activity, adherence, and health related quality of life among individuals with arthritis was examined using the 2007 Behavioral Risk Factor Surveillance System. The sample included 33,071 individuals with self-reported, physician-diagnosed arthritis who were 45 years or older. To answer the research questions, three sets of data were created: a whole sample (n=33,071), those 45-64 years old (n=17,607), and those 65 years or older (n=15,464). The conceptual framework for the study was based on the Behavioral Model of Health Services Utilization. The variables of interests were physicians\u27 recommendations for physical activity, adherence to physical activity guidelines, health related quality of life (measured as physically and mentally unhealthy days), age, sex, race, education, marital status, employment, income, health insurance, personal physician, emotional support, body mass index, activity limitations, health status, and co-morbidities. The analysis included univariate, bivariate statistics, logistic regression, and negative binomial regression models. Results indicated that older adults were less likely (OR=0.86) to receive physicians\u27 recommendations for physical activity compared to the group 45-64 years old. Those who did not receive physicians\u27 recommendations were less likely (OR=0.94) to adhere to physical activity guidelines compared to those who adhered. Those who did not adhere to physical activity guidelines had higher physically (14%) and mentally unhealthy days (12%) compared to those who adhered to physical activity guidelines. In both age groups, the number of physically unhealthy days was 12%-18% higher, for those who did not adhere to physical activity guidelines than those who adhered to physical activity guidelines. However, the associations between physicians\u27 recommendations and adherence, and adherence and mentally unhealthy days, were different for the age groups
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
Preventing Chronic Disease (PCD)
Get PDFIntroductionPhysical activity is beneficial for reducing pain and improving health-related quality of life among people with arthritis. However, physical inactivity is prevalent among people with arthritis. Health care providers\u2019 recommendations act as a catalyst for changes in health behavior. However, information about the effectiveness of such recommendations is limited in the arthritis literature. We examined the association between providers\u2019 recommendations for physical activity and adherence to physical activity guidelines for adults with arthritis and whether adults\u2019 age influenced this association.MethodsWe used combined data of adult respondents aged 45 years or older with provider-diagnosed arthritis (N = 10,892) from the 2011 Behavioral Risk Factor Surveillance System to conduct a retrospective, cross-sectional study. We used a multivariable logistic regression model to examine the association between health care providers\u2019 recommendations and adherence to physical activity guidelines among adults with arthritis.ResultsAdults with arthritis who received health care providers\u2019 recommendations for physical activity were more likely (odds ratio, 1.22; 95% confidence interval, 1.12\u20131.32) to adhere to physical activity guidelines than those who did not, after controlling for relevant covariates. Adults\u2019 age did not influence the association between providers\u2019 recommendations and adherence to physical activity (odds ratio, 1.00; 95% confidence interval, 0.99\u20131.00), after controlling for covariates.ConclusionHealth care providers\u2019 recommendations are associated with adherence to physical activity guidelines among adults with arthritis. Providers should recommend physical activity to adults with arthritis
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
