Evaluating the Association of Gender as it Pertains to Health-Related Quality of Life Outcomes in Chronic Low Back Pain Patients
No full textBACKGROUND: Six hundred and nineteen million individuals worldwide are affected by low back pain, with this number estimated to increase to 850 million by the year 20501. Low back pain is also the leading cause of disability worldwide2 and contributes to the limitation of activities and needing leave from work resulting in severe medical burdens and economic costs3,4. Males and females (referred to as gender throughout this project based on variables in the NIH Minimum Dataset form for Chronic Low Back Pain) have recorded differences in chronic low back pain outcomes including, but not limited to, treatment outcomes and psychosocial outcomes. Individuals with female sex traditionally take on the female gender with associated norms and roles, and those with male sex often take on male gender and associated roles. Previous literature on this topic varies by location and typically reports on local patients. The PRECISION Pain Research Registry differs from other research projects because the participants involved in this study are from locations within the continental United States. This diversity in terms of location, ethnicity, and race of study participants allows a larger and more applicable representation of the U.S. population in terms of chronic low back pain management. Discrepancies on whether gender has an effect on health-related quality of life outcomes in chronic low back pain patients in the literature is controversial. Thus the link between gender and chronic low back pain outcome is unknown and is the focus of this study, in which we will use the PRECISION Pain Research Registry to examine the relationship. HYPOTHESIS: We hypothesize that males and females with chronic low back pain have different health-related quality of life outcomes and these differences are correlated to pain catastrophizing and pain-self efficacy scores. The specific aims of the project include (1) analyzing the association between gender and pain catastrophizing in chronic low back pain patients, (2) analyzing the association between gender and pain self-efficacy scores in chronic low back pain patients, and (3) using repeated measures to assess differences between males and females in chronic low back pain outcomes pertaining to health-related quality of life over a 12-month period. METHODS: Data from 1,478 patients in the Pain Registry for Epidemiological, Clinical, and Interventional Studies and Innovation (PRECISION) were analyzed using factors such as gender, age, race, ethnicity, smoking habits, low back pain duration, opioid use for low back pain treatment, occurrence of low back pain surgery, education level, comorbidities, non-pharmacological treatments, and body mass index (BMI). Importantly, this project conducted analysis to determine the association between gender and pain catastrophizing, pain self-efficacy, and health-related chronic low back pain outcomes. The health-related quality of life outcomes of sleep disturbance, pain interference, anxiety, depression, and energy levels are taken from the negative outcomes from the Patient-Reported Outcomes Measurement Information System (PROMIS) scale. RESULTS: Overall, there were no statistically significant associations between gender and pain catastrophizing scores with males having slightly higher scores compared to females. No association was seen between gender and pain self-efficacy. Male patients once again had slightly higher scores but the mean score difference was not significant. Results from interaction term analysis showed that pain catastrophizing and pain self-efficacy scores on their own have an effect on SPADE health-related quality of life outcomes but upon the introduction of gender, the effect becomes negligible

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
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
