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
Levels of C-reactive protein, creatine kinase-muscle, and aldolase A are suitable biomarkers for detecting risk factors for osteoarthritic disorders: A novel diagnostic protocol
Get PDFThe present study deals with the evaluation of the levels of biochemical markers such as CRP, CK-MM, and AldoA and determine their correlations with risk factors for OADs. Baseline data from 297 patients with OADs and 315 participants without OADs aged 40 to 80 years old were collected in this cross-sectional study
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
Role of Jumpstart Nutrition®, a Dietary Supplement, to Ameliorate Calcium-to-Phosphorus Ratio and Parathyroid Hormone of Patients with Osteoarthritis
No full textThe aim of this study was to use Jumpstart Nutrition® bone supplementing combination with vitamin-K2 and coenzyme-Q10 characterized by an innovative delivery system that improves bioavailability of calcium-to-phosphorus ratio (CPR) and parathyroid hormone (PTH) in the management of osteoarthritis (OA). This eight-week registry included 108 patients treated for symptomatic OA confirmed with radiological images. On top of that, 63 patients used Jumpstart Nutrition® supplement, mainly prepared with calcium, phosphorus, coenzyme-Q10, vitamin-K2, vitamin-D2, vitamin-C, folic acid, curcumin and boswellic acids. Rescue medication was also recommended. Patients’ pain and functional capacity through outcome measures—knee-injury osteoarthritis outcome scale (KOOS) and Karnofsky performance scale (KPS), biomarkers such as levels of CPR, PTH and 25-hydroxy-vitamin-D were evaluated for the groups with and without supplement using appropriate kits. After eight weeks, the levels of CPR and PTH were all significantly improved (p < 0.001), fewer subjects had to use rescue medication (p < 0.05) and variation of pain and functional capacity under KOOS and KPS (p < 0.05) of the patients in the supplement group compared to controls. This registry study indicates that Jumpstart Nutrition® can be used safely for effective management of OA patients for the amelioration of CPR, PTH and functional activities confirmed with biomarkers and radiological images correlated with the Kellgren-Lawrance scale
Obtaining normal flexion and extension of knee joints on supine, prone and standing positions in osteoarthritis by topical phyto-therapeutic treatment irrespective of age and sex
No full textOsteoarthritis (OA) is not a simply process of wear and tear, but an abnormal remodeling of joint tissues driven by a host of inflammatory mediators, including disorders of specific nerves within the affected joint. The common risk factor of OA includes age, sex, prior joint injury, obesity, genetic predisposition and mechanical factor, including malalignment and abnormal joint shape. This paper reports for the first time that normal flexion and extension of knee joints on supine, prone and standing positions in osteoarthritis by topical phytotherapeutic treatment can be achieved, with sustenance, irrespective of age and sex
Tropical phytotherapeutic treatment for achieving knee symmetry in osteoarthritis – A sustainable approach
No full textThroughout the world a large number of patients suffering from osteoarthritis are undergoing knee surgery and knee replacement every year. Though the surgery or replacement methods are expensive , these cannot make both knees symmetrical in all anatomical measurements.The present paper , reports for the first time , a noble method ,alternative to knee surgery by topical applications of phytoconstituents.The treatment involves topical applications of phytoconstituents from medicinal plants by manually applied with wooden roller and pluse-therapy technique for a period of 42days. The patients recover completely from osteoarthritis pain and both their knees become symmetrical anatomically , supported by pathological and radiological observations
