Feasibility and Effects of TAI CHI for the Promotion of Sleep Quality and Quality of Life: A Single-Group Study in a Sample of Older Chinese Individuals in Hong Kong
No full textPoor sleep in later life is a global issue that reduces many individuals' quality of life (QOL). The purpose of this pilot study was to test the feasibility and effects of a simplified tai chi exercise intervention on sleep quality and QOL among Chinese community-dwelling older adults with poor sleep quality. This single-group, descriptive feasibility study included 34 individuals with poor sleep quality who agreed to participate in a 12-week tai chi intervention. Twenty-six individuals completed the program (23.5% dropout rate). Older adults with poor sleep quality who completed the intervention showed significant improvement in the Medical Outcomes Study Short Form-36 mental component and the Pittsburgh Sleep Quality Index global and component scores. The low recruitment and attendance and high dropout rates might be associated with participants' age, gender, and sleep quality. Further long-term studies are required to examine the potential effects of the tai chi intervention
(29(2):167-174)Influence of harvest date on the yield and quality of mat rush (Juncus effusus L. Var. decipiens, Buch)
No full text本試驗以中莖種藺草Fs-72-p-8006 與細莖種藺草岡山3 號為材料，探討插值後180、195、210與225日等四種收穫期對藺草產量與品質的影響，藉供栽培之參考。不同生育階段之調查顯示，藺草株高之增長速率以插植後120~150日問最高，90~120日問次之，180日後之生長已趨緩漫，二品種之表現相似。分蘗之增加亦以插植後90~150日間最為迅速，細莖種岡山3號之分蘗數顯著高於中莖種FS-72-P-8006。二品種之乾草產量及株高均以210日處理最高，中莖種之產量為13,580 kg / ha，有效莖長127.5 cm，細莖種之產量為11,510 kg / ha，莖長118.0 cm，均優於其他收穫期處理。藺草之髓徑與莖徑呈密切正相關，且無處理間差異，中莖種之平均莖徑為1.49 mm，髓徑為1.41 mm，細莖種則分別為1.06 與1.00 mm。品種間比較，中莖種FS-72-P-8006 之產量，品質及其他農藝性狀表現均較佳。試驗結果顯示，就產量與草長分級而言，中莖種FS-72-P-8006 之收擭期以插植後210日，細莖種岡山3號則以225日最為適宜。
A medium-stem line Fs-72-P-8006 and a slim-stem variety Kangshan No. 3 were tested in this experiment to seek a harvest date for high yield and good grass quality of mat rush grown in Taiwan. The above-ground portion of plants was harvested 180, 195, 210 and 225 days after planting and some important agronomic characters were investigated.
Experimental results showed that mat rush harvested at 210 days after planting produced the highest dry straw yield, plant height, tiller number and stem diameter among the four treatments for either variety. The yield of Fs-72-P-8006 and Kangshan No. 3 after 210-day growth was, respectively, 13,580 and 11,510 kg/ha. Corresponding values of plant height and stem diameter for the two varieties were 127.5 cm vs. 118.0 cm and 1.49 mm vs. 1.06 mm, respectively. The medium-stem Fs-72-P-8006 performed better than the slim-stem variety Kangshan No. 3.
No significant difference in pith diameter was found in relation of various growth durations. Average pith diameter was 1.41 mm for Fs-72-P-8006 and 1.00 mm for Kangshan No. 3. The former was significantly thicker than the latter.
In conclusion, a growth period of 210 to 225 days was recommended for growing mat rush in Taiwan. A shortened growth would cause lower dry straw yield and inferior grass springness and hence would lower the economic value of the crop
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
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
