No full textA pilot study was carried out investigating women’ s sexual health in the postnatal period. Postal questionnaires were sent to a cohort of 158 primiparous women approximately 7 months after delivery. Women who had resumed sexual intercourse were asked a detailed set of questions about problems experienced, sexual practices, frequency of intercourse, satisfaction with sex life, and consultation for postnatal sexual problems. All women were asked about the information they received on postnatal health prior to the birth and any information or help and advice they received from health professionals on the subject after the birth. Ninety-eight women (62%) responded. Women experienced significant levels of morbidity in the postnatal period; 3 months after delivery 58% experienced dyspareunia, 39% experienced vaginal dryness, and 44% suffered loss of sexual desire. These figures had reduced to 26, 22, and 35%, respectively, by the time of answering the questionnaire (approximately 8 to 9 months after delivery). Compared to before pregnancy, there was a decrease in frequency and satisfaction with sexual intercourse, although sexual practices changed little. Of the 67 women who reported a postnatal sexual problem, only 19% discussed this with a health professional. Conversations with health professionals in routine postnatal health contacts were mainly about contraception, and only rarely discussed problems with intercourse
Postnatal depression and sexual health after childbirth
No full textOBJECTIVE: To investigate the sexual health experiences of depressed and nondepressed postnatal women within a 6-month postnatal period. METHODS: This cross-sectional study used obstetric records and postal survey 6 months after delivery from a cohort of primiparous women (n = 796) delivering a live-born infant at St. George's NHS Trust, London. Women self-reported sexual problems and sexual behaviors and completed the Edinburgh Postnatal Depression Scale. RESULTS: Of the 796 parturients, 484 responded (61%), and 468 completed the survey questions on depression and sexual health (97%). Of the latter, 57 (12%) fit the Edinburgh Postnatal Depression Scale criteria. Comparing the depressed with nondepressed women, resumption of sexual activity occurred with 77% versus 90% (P =.003), and the median number of specific sexual problems reported was two versus one, respectively (P =.009). CONCLUSION: Sexual health problems were common after childbirth in both depressed and nondepressed women; however, depressed women were less likely to have resumed intercourse at 6 months and more likely to report sexual health problems. Given the frequency of sexual health problems, postnatal sexual morbidity cannot be assumed to be simply a product of the depressed mental stat
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
