Predictors of mothers� postpartum body dissatisfaction based on demographic and fertility factors
Get PDFBackground: There are fundamental and rapid changes in body shape during pregnancy, some of which persist for an extended time after delivery and may cause dissatisfaction with body shape. Therefore, we conducted this study to determine predictors of body dissatisfaction at six months postpartum based on demographic and fertility factors. Methods: This cross-sectional study was conducted on 300 women who referred to seven health centers affiliated with Iran University of Medical Sciences, Tehran, Iran. The sampling was multistage and we collected data from a demographic and fertility questionnaire and Cooper�s Body Shape Questionnaire (BSQ-34). The independent t-test, Mann-Whitney U test, chi-square test, one-way ANOVA, Kruskal-Wallis, Pearson correlation coefficient, and multiple linear regression were used for data analysis. The level of significance was set at P < 0.05. Results: The mean age of participating women was 29.77 (standard deviation: 5.9) years. Body dissatisfaction had a statistically significant association with variables such as body mass index (BMI) at six months postpartum, gestational age, the receipt of information about body shape, spouse�s views on the shape of a woman�s body, and mode of delivery. These variables predicted 34 of body dissatisfaction based on multiple linear regression. Conclusion: Postpartum body dissatisfaction is related to a several variables. Paying attention to these variables will help to plan and improve postpartum counseling and educational programs. © 2021, The Author(s)
The relationship between social support and perceived stress in the mothers of infants with colic
Get PDFBackground: High stress levels in the parents of infants with colic have negative impacts on their quality of life. Maternal concerns with infants� needs can be reduced through social support. Objectives: The aim of this study was to assess the relationship between social support and perceived stress in the mothers of infants with colic. Methods: This cross-sectional study was carried out on 200 mothers of infants with colic referred to 14 healthcare centers affiliated to Iran University of Medical Sciences in year 2017. A convenience sampling method was used. Demographic data form, Cohen perceived stress and Vaux�s perceived social support questionnaires were used for data collection. Descriptive and inferential statistics were used for data analysis. P < 0.05 was considered statistically significant. Results: There was a statistically significant positive correlation between social support and perceived stress (r = 0.31, P = 0.001). In other words, with increase in social support, perceived stress would be increased. However, the support of the spouse in the form of childcare could reduce perceived stress in the mother (P = 0.001). Conclusions: The results of this study showed that with increase in social support, perceived stress in the mothers of infants with colic also would be increased. However, spousal assistant in childcare is accompanied by a reduction in perceived stress in mothers. © 2019, Author(s)
Psychological well-being of infertile women and its relationship with demographic factors and fertility history: a cross-sectional study
No full textBackground: Infertility leads to a wide range of psychological injuries that may reduce psychological well-being. This study aimed to determine the psychological well-being of infertile women and its relation with demographic factors and fertility history. Methods: This cross-sectional study was conducted on 300 infertile women referred to three infertility centres, Tehran, Iran. The sampling was continuous. We collected data from a self-generated demographic and fertility questionnaire and Ryff's Psychological Well-being Scale (PWB). Data analysis was done by independent t-test, one way ANOVA. The significance level was set at P < 0.05. Results: The results showed that there was no significant relationship between demographic variables including age, occupation of each couple, spousal�s education, economic status and place of residence with PWB, but the mean score of PWB was significantly different in women's educational levels (P = 0.03). There was also a significant difference between the mean score of PWB among different groups in the duration of marriage (P = 0.01). Fertility characteristics variables include the duration of infertility, duration of treatment of infertility, and current treatment were not the relation with PWB. However, the mean score of PWB in the number of IVF (P = 0.003) and the failed IVF pregnancies (P = 0.01) had a significant statistical difference. Conclusion: The results showed that PWB related to several variables. Paying attention to these variables can help in the preparation and development of counseling or educational programs. © 2021, The Author(s)
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
