Effectiveness of weight control program on nutritional status and knee pain in overweight older adults
Full text linkPurpose: A common health problem in older adults is knee pain, particularly those with overweight. Weight control is an appropriate approach for overweight older adults suffering from knee pain. This study aimed to examine the effects of weight control program using community and group support on nutritional status and knee pain in overweight older adults with knee pain. The specific research purposes were to: 1) compare mean scores of nutritional status (body mass index and waist circumference) and knee pain in the experimental group before and after the program, and 2) compare mean differences of nutritional status (body mass index and waist circumference) and knee pain between the experimental and the control groups.
Methods: This study employed quasi-experimental research with 2-group pre-post design. Through convenience sampling with inclusion criteria, the sample included 60 overweight older adults with knee pain who lived in two communities in Bangkok, Thailand. The 30 subjects in the experimental group in a community participated in the 12-week weight control program including four stages: Raising community awareness, Aiming at target health outcome, Mobilizing change, and Assuring synergy through group activities. The program consisted of 14 activities addressing food exchange and behavioral modification for food consumption, arm swing exercise, knee exercise, modification of postures in daily living and arrangement of the surrounding environment in the community as well as monitor of body mass index and waist circumference. The control group received only leaflets and booklets. Data were analyzed using descriptive and inferential statistics including Chi-square test, Paired t-test, Independent t-test, and Wilcoxon Signed Ranks test.
Results: Results revealed that the mean age of the subjects was 70.8 (SD 5.8) years, ranging from 60-84 years. There were no significant differences in demographic characteristics between the control and the experimental groups. At baseline, the mean body mass index, waist circumference, and knee pain in the control group were 27.2 kg/m2 (SD 3.5), 94.6 cm (SD 9.5), 5.4 (SD 1.6), respectively and those in the experimental group were 27.9 kg/m2 (SD 3.5), 95.3 cm (SD 8.8), 6.7 (SD 1.9), respectively. There were no significant differences in body mass index and waist circumference between the control and the experimental groups at baseline, except for knee pain. After the program, the experimental group had body mass index (27.2: SD 3.1), waist circumference (93.6: SD 8.7) and knee pain (4.4: SD 1.9) less than before the program with statistical significance (t = 2.128, p =.042; t = 6.599, p \u3c.001; Z = -4.745, p \u3c.001, respectively). Mean differences in body mass index (-.69), waist circumference (-1.74), and knee pain (-2.4) in the experimental group were more than differences in body mass index (.01), waist circumference (.44), and knee pain (.13) in the control group with statistical significance (t = 2.124, p =.038; t = 7.209, p \u3c.001; t = 7.447, p \u3c.001, respectively).
Conclusion: The weight control program was effective. The results suggested approaches to behavioral modification on food consumption behaviors and group support for arm swing exercise and knee exercise as appropriate for the overweight older adults with knee pain
Effects of program promoting sodium intake reduction on knowledge and urinary sodium in nursing students
Full text linkThis quasi-experimental research with one-group self-control aimed to examine effects of the program promoting sodium intake reduction on knowledge of sodium intake and urinary sodium in 173 nursing students. After the program, the participants\u27 knowledge was significantly higher while urinary sodium was lower than before the program and baseline

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
Effects of armswing exercise on cardiovascular outcomes in postmenopausal women with prehypertension: Randomized controlled trial
Full text linkThe objective was to study effects of arm swing exercise on cardiovascular outcomes in postmenopausal women with prehypertension. A randomized control trial was conducted, randomly assigned. The armswing exercise program was performed by experimental group comparing with control group. The armswing exercise had health benefits for postmenopausal women with prehypertension
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
