SARS-CoV-2 pandemic: An overview
By the end of May 2020, SARS-CoV-2 pandemic caused more than 350,000 deaths worldwide. In the first months, there have been uncertainties on almost any area: infection transmission route, virus origin and persistence in the environment, diagnostic tests, therapeutic approach, high-risk subjects, lethality, and containment policies. We provide an updated summary of the current knowledge on the pandemic, discussing the available evidence on the effectiveness of the adopted mitigation strategies
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
The relationship between integrated care and cancer patient experience: A scoping review of the evidence
Background: Health policy documents underscore the need to develop organizational models to optimize the integration of cancer care pathways around patient needs. Still, there is a lack of clarity about the meaning of integrated care as perceived by patients. The purpose of this study is to explore the relationship between the integration of cancer services and patients' experience. Materials and methods: We completed a scoping review of the available literature searching PubMed, Embase and Scopus from the earliest date available in each database to February 2013. Results: From 1760 bibliographic records, we identified 30 articles relevant for this analysis. Based on the qualitative conventional content analysis, we defined three integrated care approaches: "individual care provider", "team care providers", "mixed approach", that impact on the following patient experience dimensions: patient satisfaction, quality of life, psychological and physical outcomes, continuity of care and empowerment. Conclusions: This scoping review identifies important aspects of integration from patients' perspective and suggests that policy makers should consider how to best include patients' experience into the patient care pathway. Future perspectives include engaging patients, family members, caregivers and clinicians in an on-going dialogue and have them participate actively in developing, implementing and evaluating policies, services and programmes
Diabetes risk reduction diet and the risk of pancreatic cancer
Purpose To evaluate the role of a diabetes risk reduction diet (DRRD) on pancreatic cancer risk. Methods We used data from a hospital-based case-control study conducted in Italy between 1991 and 2008; the study included 326 incident pancreatic cancer cases and 652 controls matched by age, gender and study center. Subjects' usual diet was collected through a valid and reproducible food frequency questionnaire. A DRRD score was derived from 8 dietary components: cereal fiber, total fruit, coffee, polyunsaturated to saturated fats ratio and nuts (higher score for higher intake), and dietary glycemic index, red/processed meat and sugar-sweetened beverages/fruit juices (higher score for lower intake). The score ranged 8-37, with higher values indicating greater DRRD adherence. Odds ratios (ORs) of pancreatic cancer according to the DRRD score were estimated using multiple conditional logistic regression models. Results After allowance for confounding factors, the DRRD score was inversely related to pancreatic cancer risk, with ORs of 0.55 (95% confidence interval, CI 0.38-0.80) for the highest versus the lowest score tertile (p for trend across tertiles = 0.002) and 0.84 (95% CI 0.75-0.95) for a 3-point score increment. The exclusion of diabetic subjects and additional adjustment for vegetable intake did not change the results. Inverse associations were observed in subgroups defined by age, gender, education, body mass index, smoking and total energy intake. Conclusion Study findings suggest a protective role of high adherence to a DRRD on pancreatic cancer risk
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
We 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
We 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
