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

No full text[Contraception in teenagers. Medico legal implication].
No full textContraception in adolescence is an issue which, due to its clinical and medico-legal implications, requires an in depth and clear knowledge of the general principles that govern contraception in minors, as stated in a broad body of laws. The position of the physician is complex, since he/she must comply with the law whilst protecting the minor. The physician has to provide answers to many questions: Can health care facilities and guidance centers administer to the minor, by medical prescription, the means necessary for her to make free choices in the area of responsible procreation without parental authorization? How must the gynecologist go about prescribing the morning after pill ? Emergency contraception, that is the morning after pill , has proven to be extremely helpful for adolescents whose physical and psychic health could be undermined by an unwanted pregnancy, so that it is the physicians duty to protect it. In our legislation there are principles that guarantee the right of minors to conscious and responsible motherhood; however, there are no provisions that allow for such principles to be easily enforced. Consequently, only the health worker can actually interpret the law provisions and translate them into concrete action. Laws are therefore the only point of reference for the physician, who is then responsible for enforcing them in clinical practice, always fully respecting the rights of the minor. The aim of paper is to provide experts with a correct legislative framework on contraception in adolescents, in order to facilitate his/her work in prescribing treatment while at the same time protecting the health of the minor
Preparation for childbirth in different cultures.
No full textAnthropologically childbirth is an enigma because every woman experiences an identical physiological and biological process, wherever the event takes place: from a hut in the jungle to a modern hospital in the United States. Differences are due to the way that pregnancy, birth and the postnatal period are treated. For most women in developing countries, being a woman means being a mother: a female is not a woman until she has given birth to a child. Therefore during pregnancy she has to follow precise rules and regulations with ritual meanings for her protection and that help her get into the role of a mother. Medicine offers important technological resources for the prevention, diagnosis and treatment of pathology during pregnancy, but with a lack of attention to emotional support. Modern society must try to give pregnant women the trust in their bodies in order to reach the harmony necessary to give birth "willingly" and "with joy"
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
