The prevalence of and risk factors for loneliness among older people in China
No full textCopyright @ 2008 Cambridge University Press.Compared with the many studies in western countries, research on the prevalence of and risk factors for loneliness amongst older people in China is sparse. This paper reviews the current cross-national literature on loneliness and, using data from two national surveys undertaken in 1992 and 2000, assesses the prevalence of loneliness amongst older people in China and explores the factors that raise their vulnerability to the negative feeling. The reported prevalence of loneliness was 15.6 per cent in 1992 and 29.6 per cent in 2000. We suggest that part of the differential is accounted for by the differences in the methodologies of the two surveys and in the questions used to assess loneliness. The evidence from both surveys suggests that loneliness was relatively prevalent among those aged 65 or more years, females and those living in rural areas, and that these variations had greater amplitude in 2000. As in western countries, increased age, being widowed or divorced, and poor self-rated health were significantly associated with old-age loneliness in China at the two dates. Two factors positively related to loneliness were found that are specific to the Chinese context, however: living in a rural (as opposed to urban) area, and thinking that one's children are not filial. To develop our understanding of loneliness among older people in China and other non-western countries, it will be necessary to construct more rigorous and comparable measurements of loneliness and to undertake longitudinal studies of social relationships.University of Readin

An enhanced author name dataset for PubMed/MEDLINE
No full text<p>The incompleteness of author names is a well-known issue in the MEDLINE database. It was since 2002, the full author name has been systematically indexed in MEDLINE. Although many full author names have been added to MEDLINE, we still found a significant number of abbreviated names in papers published after 2002.</p>
<p>Here we built an enhanced author name dataset for MEDLINE, called EAN, achieved by linking the whole PubMed to other large literature databases and conducting a large-scale name comparison and restoration with obtained multi-sources author names. Our evaluation shows that more than 90% of author names in EAN are complete as compared to the ratio of ~60% in MEDLINE.</p>

Professor Zhang Weihua's Clinical Experience in the Application of Yongquan Acupoint
No full textSummarizing Professor Zhang Weihua's understanding of the bidirectional regulation function of Yongquan Point and his clinical application experience, the author believes that Yongquan is a meeting place of Yin and Yang qi, and both Yin and Yang qi are rooted here, which can be used to balance Yin and Yang, and proposes that Yongquan is the key point of bidirectional regulation, which has the functions of bidirectional regulation, bidirectional lifting, bidirectional replenishing. At the same time, Professor Zhang believes that Yongquan point should be combined with the corresponding stimulation method in the treatment of different diseases, which provides a new idea for the clinical treatment of some difficult diseases
In Memoriam: Prof. Jingdong Zhang
No full textCelebrating the electrochemistry legacy: Prof. Zhang was a member of the Editorial Board of ChemElectroChem as well as a valued author and reviewer. Together with her friends and colleagues Christian Engelbrekt, Xinxin Xiao and Jens Ulstrup (Technical University of Denmark) as well as Bingwei Mao (Xiamen University, China), we hope to commemorate Prof Zhang′s contributions to the electrochemical sciences by this Special ChemElectroChem Collection on the theme of “Electrochemical Materials and Interfaces”
Power prior elicitation in Bayesian quantile regression
No full textThis article has been made available through the Brunel Open Access Publishing Fund - Copyright @ 2011 Rahim Alhamzawi and Keming Yu.We address a quantile dependent prior for Bayesian quantile regression. We extend the idea of the power prior distribution in Bayesian quantile regression by employing the likelihood function that is based on a location-scale mixture representation of the asymmetric Laplace distribution. The propriety of the power prior is one of the critical issues in Bayesian analysis. Thus, we discuss the propriety of the power prior in Bayesian quantile regression. The methods are illustrated with both simulation and real data
From expectation-3-maximization to bayesian expectation-3-maximization: A latent mixture modeling-based bayesian algorithm for the 4-parameter logistic model
No full textThere is renewed interest in the four-parameter logistic model (4PLM), but the lack of a user-friendly calibration method constitutes a major barrier to its widespread application. In the present study, this researcher reformulated the 4PLM from a latent mixture modeling view and developed the Expectation-Maximization-Maximization-Maximization (EMMM) method. Combining the EMMM with the Bayesian approach, allowed the Bayesian Expectation-Maximization-Maximization-Maximization (BEMMM) algorithm to be proposed. First, the author compared the EMMM with BEMMM to confirm that the BEMMM method reduced the number of implausible estimates in EMMM. Next, when comparing the BEMMM with the Markov Chain Monte Carlo method (Culpepper, 2016) and Bayesian Modal Estimation (Waller & Feuerstahler, 2017), the results from a simulation study and a real-world data calibration indicated that the BEMMM and the MCMC are more accurate than the BME, while the BEMMM is much faster than the MCMC.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2020-05-01The student, Ci Zhang, accepted the attached license on 2018-04-11 at 15:29.The student, Ci Zhang, submitted this Thesis for approval on 2018-04-11 at 15:36.This Thesis was approved for publication on 2018-04-13 at 11:03.DSpace SAF Submission Ingestion Package generated from Vireo submission #12194 on 2018-08-31 at 17:27:19Made available in DSpace on 2018-09-04T20:47:03Z (GMT).

Frank Zhang: Hipster Extraordinaire
No full textAfter the delicate deliberation of the characters of the series Heroes of Olympus by Rick Riordan, it was decided by both writers that Frank Zhang, son of Mars, is the ultimate hipster demigod. The structure of this essay was based on a simple argument, and carefully dissects the full series in order to really convey who Frank Zhang really is. It was additionally concluded by both writers that as complicated and intricate a character as Frank Zhang is, we wanted the audience to be able to not only imagine the illustrations of the character, but to further empathize with the character\u27s emotions. Through the attendance of two separate classes, a review from the professor, and careful editing, the essay comes to a complete conclusion demonstrating our perspective on the author\u27s ultimate purpose
