Summary of an International and a Regional Symposium: Acid-Related Diseases - Improving Treatment Options
Get PDFThe author examines the clinical impact of findings from a key international workshop on acid peptic disorders, “Appropriate acid suppression for the healing of acid-related diseases,” and from an important meeting which summarized results of a cross-Canada study of the symptomatic treatment of dyspepsia due to esophagitis and duodenal ulcer disease
Basic Science for the Clinical Gastroenterologist: A Review of the Recent Literature on the Small Bowel – Part II
Get PDFIn small bowel science, as in all parts of medicine, there has been a recent explosion of information. This is the second of a two-part series in which the scientific basis of clinical gastroenterology practice and its future are considered. Advances in understanding the mechanisms of intestinal transport are examined, followed by a perspective of intestinal adaptation in health and disease. The author also discusses clinically important areas of motility and bloodflow
Medical Tretment of Peptic Ulcer Disease: Should the Emphasis Be Altered in View of Laparoscopic Surgery
Get PDFIn the past H2-receptor antagonist era, there was initially a lull as more and more ‘me-too’ drugs were developed. Then came the excitement of the proton pump inhibitors and the controversy of the pros and cons of moderate versus potent acid inhibition. The most recent explosion of knowledge has been in the discussion of pH versus Helicobacter pylori, but on the horizon is lurking the promise of the resurgence of the surgical option
A Suggested Approach to Patients with Dyspepsia
Get PDFA comprehensive review of dyspepsia is presented. Topics include causes of dyspepsia, prevalence, causes of symptoms (motility abnormalities, visceral hypersensitivity, psychosocial aspects, role of Helicobacter pylori), investigations of patients with dyspepsia and, finally, whether there is effective treatment
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
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
