Methoden zur Analyse der regionalen dermatologischen Versorgung am Beispiel Hamburgs
No full textHintergrund: Regionale Ungleichheiten in der Gesundheitsversorgung werden häufig mit dem Stadt‐Land‐Unterschied in Verbindung gebracht. Untersuchungen haben aber gezeigt, dass sich bei einer kleinräumigen Betrachtung auch in Städten regionale Versorgungsdisparitäten ausmachen lassen. Für deren Bewertung sind neben Versorgungsgrad noch weitere Größen wie die Erreichbarkeit hinzuzuziehen. Zielsetzung der vorliegenden Arbeit war das Aufzeigen methodischer Werkzeuge zur Bewertung der dermatologischen Versorgung am Beispiel Hamburgs. Besonderer Fokus wurde auf die Erreichbarkeit gelegt. Methoden: Auf Basis der 97 Hamburger Stadtteile wurde zunächst die Verteilung der 101 berücksichtigten Dermatologen sowie der Versorgungsgrad ermittelt. Anschließend wurde eine Netzwerkanalyse zur Erreichbarkeit durchgeführt. Ergebnisse: In Hamburg bestehen regionale Unterschiede im Versorgungsgrad und in der Erreichbarkeit von Dermatologen. Je nach Stadtteil liegt der Versorgungsgrad zwischen 44,9 % (unterversorgt) und > 500 % (überversorgt). Ähnliche Unterschiede zeigen sich bei der Erreichbarkeit. 94,5 % der Einwohner Hamburgs erreichen den nächsten Dermatologen innerhalb von zehn Minuten (PKW). Entsprechend dem Stadtteil und Verkehrsmittel kann der Zeitaufwand auf über 30 Minuten ansteigen. Schlussfolgerungen: Mittels des Versorgungsgrades können Unterschiede in der dermatologischen Versorgung Hamburgs aufgezeigt werden. Anhand der Netzwerkanalyse wurde jedoch ersichtlich, dass es trotz dieser Unterschiede nur wenige Defizite in der Erreichbarkeit des nächsten Dermatologen gibt. Netzwerkanalysen können damit als wertvolle und ergänzende Methode dienen, um das regionale Versorgungsgeschehen zu bewerten
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
Efficacy and Cardiovascular Safety of Roxadustat in Dialysis-Dependent Chronic Kidney Disease: Pooled Analysis of Four Phase 3 Studies
No full textIntroduction: This integrated phase 3 analysis examined efficacy and cardiovascular safety for roxadustat vs erythropoiesis-stimulating agents (ESAs) in dialysis-dependent patients. Methods: Efficacy and safety results from four phase 3, randomized, open-label studies comparing roxadustat to ESAs (PYRENEES, SIERRAS, HIMALAYAS, ROCKIES) in dialysis-dependent patients with anemia of chronic kidney disease (CKD) were evaluated by study, pooled population and in two subgroups: incident dialysis and stable dialysis. The primary efficacy endpoint per study was hemoglobin change from baseline (CFB) to weeks 28-36 using least-squares mean difference (LSMD) without rescue therapy. Pooled safety endpoints included time to major adverse cardiovascular event (MACE; myocardial infarction, stroke, and all-cause mortality [ACM]) and MACE+ (MACE plus congestive heart failure or unstable angina requiring hospitalization), ACM, and treatment-emergent adverse events (TEAEs). MACE and MACE+ were evaluated for non-inferiority at 1.8 and 1.3 margins using hazard ratios (HRs) and 95% confidence intervals (CIs). TEAEs were descriptively summarized. Results: In total, 4714 patients were randomized (2354 roxadustat; 2360 ESA). Hemoglobin CFB to weeks 28-36 achieved non-inferiority for roxadustat vs ESA in each study. Roxadustat was non-inferior to ESA for risks for MACE and MACE+ in the entire cohort (MACE: HR 1.09, 95% CI 0.95-1.26; MACE+ : HR 0.98, 95% CI 0.86-1.11) and similar to the incident dialysis and stable dialysis subgroups; ACM results were consistent with MACE and MACE+ (HR 1.13, 95% CI 0.95-1.34). TEAEs were generally comparable between groups. Conclusion: Roxadustat improved hemoglobin similarly to ESA while demonstrating comparable cardiovascular and overall safety profiles in a wide spectrum of dialysis-dependent patients with anemia of CKD. Roxadustat represents an oral alternative to ESAs for achieving a target hemoglobin for anemia of CKD in dialysis-dependent patients
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
