Associations Between Sensory Loss and Depressive Symptoms in a Longitudinal National Study of Ageing Adults in Thailand
No full textIntroduction: Sensory loss and depressive symptoms (DS) may be an increasing concern in ageing adults. Some previous studies in China found bidirectional associations between sensory loss and DS, but we lack information on this relationship in Southeast Asia. The purpose of this study was to assess the bidirectional association between sensory loss and DS in a longitudinal study in Thailand.
Methods: The responses of participants (≥ 45 years) of two consecutive waves (2015 and 2017) of the Health, Aging and Retirement in Thailand (HART) study were analysed. Sensory loss was assessed with self-reported questions and DS with the Center for Epidemiological Studies Depression scale.
Results: The analytic baseline sample included 3708 participants (median = 66 years) who responded to the 2015 and 2017 survey. The prevalence of vision, hearing and dual sensory loss were 25.4%, 13.3% and 7.9%, respectively, and the prevalence of DS was 12.3%. In the final model, adjusted for relevant confounders, vision, hearing, and sensory loss at baseline were positively associated with incident DS (AOR: 1.34, 95% CI: 1.01 to 1.74; AOR: 1.71, 95% CI: 1.23 to 2.38; and AOR: 1.80, 95% CI: 1.20 to 2.69, respectively). DS at baseline was not significantly associated with incident vision, hearing or dual sensory loss.
Conclusion: Baseline vision, hearing, and dual sensory loss increase the odds of incident DS, but baseline DS did not significantly increase the odds of incident vision, hearing, or dual sensory loss among ageing adults in Thailand.

Longitudinal Health Consequences of Insomnia Symptoms among Middle-Aged and Older Adults in Thailand
No full textIntroduction: Insomnia symptoms may impact on various health outcomes. It is unclear how insomnia symptoms impact on health in Thailand. In a longitudinal study of ageing adults in Thailand, the goal of the research was to evaluate the relationships between insomnia symptoms and 20 health indicators.
Methods: Prospective cohort data from the Health, Aging and Retirement in Thailand study, which included participants 45 years of age and older (N = 2863) from three successive waves in 2015, 2017, and 2020 were analyzed. Insomnia symptoms and health indicators were assessed by self-report. Generalized Estimating Equations analysis and logistic regression analysis were used to evaluate the longitudinal relationships between measures of insomnia symptoms and 20 health indicators.
Results: In 2020, 11.7% of people reported having insomnia symptoms, compared to 15.6% in 2015 and 14.6% in 2017. Insomnia symptoms were positively correlated with three poor mental health indicators (depressive symptoms, quality of life and self-rated mental health), eight poor physical health indicators (hypertension, self-rated physical health status, cardiovascular disease, diabetes, osteoporosis, chronic lung disease, kidney disease, and physical injury), and two lifestyle indicators (physical inactivity and meal skipping) in logistic regression models.
Conclusion: The study found that a number of indicators of physical and mental illness as well as lifestyle choices were linked to symptoms of insomnia. Improved detection and management of insomnia symptoms could lower indicators of physical and mental illness in Thailand.

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
