Socio-economic background, individual cost and hospital care expenditure in cases of illegal and legal abortion in Maputo
No full textThe health care expenditures of the hospital was higher for illegal than for legal abortion; Access to safe legal abortion, being less costly to society, was, however, restricted because of the significantly higher intervention cost than an illegal abortion for the individual woman
Reproductive characteristics and post-abortion health consequences in women undergoing illegal and legal abortion in Maputo
No full textIn the Maputo Central Hospital 103 women undergoing induced legal abortion (LA), 103 women with confirmed, recent illegal abortion (IA), and 100 randomly recruited antenatal clinic (AC) attenders were compared in order to find characteristic features regarding obstetric history, reproductive performance and contraceptive knowledge, attitude and practice. Women with IA were younger, had almost never undergone LA, had more often their first sexual intercourse and their first pregnancy below 20 years of age, had less knowledge of contraceptives and more often had never used contraceptives, had fewer previous spontaneous abortions and fewer previous stillbirths than LA women. There were three maternal deaths, all in the IA group. The most frequent illegal abortionist was a health worker (38%). It is concluded that, in this first comparative African study on IA and LA regarding reproductive profile and post-abortion health consequences, the former are at a disadvantage regarding early unprotected sexual intercourse with first pregnancy at a young age and with almost no experience of safe, legal abortion
Audit of uterine rupture in Maputo: a tool for assessment of obstetric care
No full textRecords of 96 women who had rupture of the uterus in labor were audited to find circumstances significantly associated with pregnancy outcome. The prevalence was 1 rupture in 424 deliveries. In 74 cases (77.1%) uterine rupture occurred after hospitalization, the remaining 22 cases being emergency transfers with rupture secondary to a delivery attempt elsewhere. History of a previous cesarean section was present in 46%, whereas 54% of the women had an unscarred uterus. Maternal mortality was 7.3% whilst perinatal mortality was 62.9%. Adverse outcome for the mother was associated with ruptures occurring in unscarred uteri (p < 0.02) and outside the Maternity (p < 0.01); this latter condition also contributed to higher fetal mortality (p < 0.002). The findings confirm that delay in reaching medical care is an aggravating factor in the evolution of uterine rupture in developing countries and suggest the need for better medical attention and timely diagnosis in laboring women with unscarred uterus
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
