Large waist circumference and risk of hypertension.
No full textOBJECTIVE: To examine the relationship between 24h ambulatory blood pressure monitoring and three commonest anthropometric measurements for obesity-body mass index (BMI), waist-to-hip ratio (WHR) and waist circumference (W).
DESIGN: Cross-sectional survey among outpatients at the Obesity Research Center.
SUBJECTS AND METHODS: Four-hundred and sixty-one overweight or obese subjects, non-diabetic, otherwise healthy, aged 20-70y, of either sex, were consecutively recruited. All subjects underwent 24h ambulatory blood pressure monitoring. The population study was separated in normotensive and hypertensive males and females and the possible risk factors for hypertension (W, WHR, BMI and age) were subdivided into different classes of values.
RESULTS: Logistic regression shows that W is the most important anthropometric factor associated with the hypertensive risk. Among males with W greater than or equal to 102cm the odds ratio (OR) for hypertension is three times that of males with W < 94cm using casual BP measure (OR 3.04), nearly four times higher using 24 h BP mean (OR 3.97), and even five times higher using day-time BP mean (OR 5.19). Females with W greater than or equal to 88 cm have a risk for hypertension twice that of females with W < 80 cm, whatever BP measurement was take (casual, 24 h or day-time). Males with WHR greater than or equal to0.96 and females with WHR greater than or equal to0.86 show significant OR for hypertension only by 24 h SP measurement and by day-time BP measurement. BMI seems to have no significant relationship to hypertensive risk. Age shows a significant relationship to hypertensive risk only considering males aged greater than or equal to 55 y and females aged greater than or equal to 50 y.
CONCLUSION: The waist circumference seems to have a strong association with the risk of hypertension, principally by the ambulatory BP monitoring, when compared with casual BP measurement
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
Stress management and factors related to the deployment of Italian peacekeepers in Afghanistan
No full textThis cross-sectional study evaluated the stress levels in Italian military personnel involved in a peacekeeping (PK) mission in Afghanistan and a homogeneous group stationed in Italy (SI group). The study was performed from April 2004 to June 2004 in a sample of 160 long-time, career volunteers of the Rossi Barracks of the Alpini di L'Aquila (Italy) (SI group, n = 120; PK group, n = 40). A 10-item, self-evaluation questionnaire proposed in the U.N. Stress Management Booklet was administered to each volunteer. The total item score (TIS) values for the 10 items for the two groups were calculated. These values were greater for the PK group than for the SI group for all 10 items. The TIS values were grouped into three classes of symptoms, anxiety symptoms (items 1-4), stress-induced depression (items 5-7), and posttraumatic stress (items 8-10). The class total item score (CTIS) values were then calculated as the sum of the respective TIS values. The three CTIS values for the PK group were greater than those for the SI group. In particular, the anxiety CTIS was 72 points greater in the PK group (p < 0.001). Therefore, the peacekeepers were inclined to have a greater increase in anxiety symptoms. Consequently, antipanic techniques could be used to reduce anxiety and progressive muscular relaxation training, an important preventive relaxation technique, to face stressors and to reduce clinical anxiety
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
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
