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
Alternative conceptions of comparability
No full textComparable examinations have to be at the same standard. But what do people mean by ‘examination standard’ and what kinds of comparibility are expected? How is evidence to be gathered about these types of comparability and are all of these approaches valid? This chapter outlines different definitions of examination comparibility used in England by academics and the expectations of the media and general public. The purposes to which assessment results are put are discussed, as the alternative conceptions of examination comparability are linked to the uses of the assessment results. Given that there are different approaches, some commentators have proposed that we should select a single definition of examination standards and stick to it, so that the system is clearer and false expectations are not raised about that the examination system can realistically deliver. Whether a particular definition of examination standards can be prioritised above others is considered, we well as the implications of doing so
Implementation of universal antenatal screening for HIV and hepatitis B-lessons for future work
No full textThis paper describes the successful implementation of
universal antenatal screening for HIV and hepatitis B in
Southampton and South West Hampshire Health Authority.
This was achieved through formation of a multi-disciplinary
planning group of clinicians and managers from local trusts.
The approach taken in implementing screening is described,
key elements of this being the appointment of screening coordinators and consultation with local midwives to ensure
their training needs were addressed. Lessons for future work
are discussed
Eating for two? The unresolved question of optimal diet in pregnancy.
No full textUnequivocal evidence of the importance of fetal nutrition as a driver of intrauterine growth has come from a range of experimental studies in which nutrient supply to the fetus is manipulated (1). The dependence of the fetus on a sufficient supply of nutrients to support its successful growth and development highlights the importance of adequate maternal nutrition to ensure that fetal nutrient needs can be met. However, the complex supply chain between maternal diet and fetal nutrient supply means that fetal nutrition and maternal nutrition are not the same (1); and for human pregnancies, the definition of what is optimal, in terms of maternal diet before and during pregnancy, remains unknown. Across the world, diets vary hugely, both in quantity and quality, and even in developed settings there is significant variation in the quality of young women’s diets, with consequent differences in patterns of micro- and macronutrient intake (2). But do such variations in maternal diet matter to the fetus
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
