Infertility Patients’ Motivations for and Experiences of Cross-Border Reproductive Services (CBRS): An Asynchronous Online Investigation
No full textIVF enables individuals experiencing infertility the opportunity to achieve conception. ICMART estimated that over 3.5 million babies have been born as a result of IVF between 1978 and 2008 (Adamson, 2009).
In the last decade, there has been a steady rise in use of CBRS (Pennings et al., 2009). The ESHRE Task Force on Ethics and Law (Pennings et al., 2008) estimated in just 6 EU countries approximately 25,000 patients travelled to another country for IVF cycles.
Although some individual cases of CBRS have attracted considerable media attention and there is growing professional interest, there is limited evidence on patient perceptions of CBRS (Hudson et al. 2011).
The aim of this poster is to present an overview of patients’ motivations for, and experiences of, their cross border reproductive treatments
Wither the HFEA and the fate of donor registers?
No full textThis comment considers the proposals to disband the Human Fertilisation and Embryology Authority (HFEA) under the auspices of the Government's review of Arm's-Length Bodies in the NHS. The comment highlights some of the difficulties this might raise in relation to the Register of Information held by the HFEA, and urges the need for greater consideration of the most appropriate homes for information, advice and services for donor-conceived persons in the UK

The role of birth certificates in relation to access to biographical and genetic history in donor conception
No full textIn 1984, among its recommendations for the regulation of assisted conception services in the UK, the Warnock Committee proposed that the birth certificate of a donor-conceived person should record the fact of donor conception. While this proposal was never implemented, over twenty years later, a Joint Committee of the House of Lords and House of Commons recommended the use of birth certificates as a means of enabling donor-conceived persons to learn the nature of their conception. In response, the Government has committed to review the role of birth certificates. This paper represents an initial contribution to this exercise. It provides an overview of the legislative, policy and practice context of disclosure of donor conception, outlines arguments against and in favour of potential changes to birth certificates, and describes and critiques current propositions for revising birth certification. The paper concludes that there is a case for revising birth certificates and outlines a workable model to promote disclosure without compromising privacy concerns
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
