Experimental Study of Vitamin D Administration on Salivary Cortisol Levels in Postmenopause Women
No full textBackground: Menopause marks a major transition in a woman's life. The
definition of menopause is 12 months of amenorrhea or the cessation of menstrual
periods without other causes. Menopause is associated with problematic
symptoms, including hot flashes, sleep problems, mood disorders, sexual
dysfunction, genitourinary dysfunction, weight gain, and cognitive decline. Stress
is closely related to the HPA axis and the adrenal glands as the organs that secrete
the hormone cortisol. Vitamin D supplementation has been used for the treatment
of menopausal disorders including stress reduction.
Methods : Quasi experimental was conducted in the LK study group in Medan
Johor District, Kwala Bekala Village from April 2025 to Mei 2025. 32
menopausal women were divided equally into 2 groups of vitamin D
administration with doses of 1000 IU and 2000 IU. Serum Vitamin D levels and
morning salivary cortisol levels before and after administration were examined in
the laboratory.
Results: The 1000 IU group before vitamin D administration (p = 0.123, r = 0.402),
and after vitamin D administration (p = 0.231 r = -0.317) and the 2000 IU group, the
results did not show a significant correlation between vitamin D serum levels and
salivary cortisol before vitamin D administration (p = 0.252 r = -0.304), and after
vitamin D administration (p = 0.495, r = -0.184). Although there is a tendency for a
negative correlation, these results are not strong enough to conclude a significant
statistical relevance.
Conclusion: In the administration of vitamin D dose 1000 IU, there was no
significant relationship between vitamin D levels and salivary cortisol levels
either before or after supplementation. Although there was a tendency for a
negative correlation, this result was not strong enough to conclude that there was a
statistically significant relationship. Although statistically the difference in the
distribution of DASS categories was not strong enough to reach the level of
significance, clinically it showed a trend of increasing benefits of the 1000 IU
dose in improving psychological symptoms compared to the 2000 IU dose.81 PagesKarya Tulis Profes

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
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
