Relationship of Nutritional Status with Oral Health Status in Visual Impairment
No full textTo analyze the relationship of nutritional status with oral health status among visual impairment. The subjects were 146 elderly people (70 males and 76 females) aged 20-72 years (mean 48.8 ± 6.2 years), Phitsanulok, Thailand. Mini Nutritional Assessment (MNA) questionnaires were administered. Oral examinations investigated the number of present teeth, DMFT and Functional Tooth Units (FTUs). According to the MNA score, 44.5% of subjects were categorized as normal nutrition, 47.3% as questionable, and 8.2 % as malnutrition. The mean numbers of present teeth and FTUs were 17.8 ± 6.9 and 6.9 ± 3.2, respectively. Subjects with malnutrition had lower numbers of present teeth (10.7 ± 1.4) and FTUs (4.3±1.7) than those with normal nutrition (20.2±0.7 and 12.3±0.5) (p≤0.05). Nutritional status of visual impaired Thai was associated with mean numbers of present teeth and FTUs. Keeping many natural teeth or having appropriate numbers of FTUs by replacing missing teeth with dentures would prevention malnutrition
Oral Health Status and Impact on Performance of Professional Soccer Players
Get PDFObjectives: To evaluate oral health, the determinants of oral health and the effect of oral health on well-being, training and performance of professional soccer players in Thailand. Methods: Twenty-nine professional soccer players in Phitsanulok FC, Thailand. Oral examination about DMFT, Quigley & Hein plaque index (PI), Löe & Silness gingival index, World Health Organization malocclusion index, pocket depth, TMJ examination and history of dental trauma were recorded. Impact of oral health on athletic performance and training was assessed using OIDP Results: The results demonstrated high levels of poor oral health including dental caries (84%), mean DMFT= 10.08 (D=8.0, M=0.84 and F=1.24), dental attrition (60%) and periodontal pocket (36%). Thirty percent of all players presented bruxism and 10 % with severe malocclusion. More than 40% of athletes were ‘bothered’ by their oral health with 28% reporting an impact on quality of life and 18% on training and performance. Conclusion: The oral health of professional soccer players Thai was poor with a resulting substantial negative impact on well-being, training and performance. As oral health is an important element of overall health and well-being, health promotion and disease prevention interventions are urgently required to optimise soccer player performance.DOI: 10.14693/jdi.v23i1.633</p
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
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
