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
Gestational surrogacy, ethics and the family
No full textThere is an increasing demand for gestational surrogacy in current reproductive medicine practice. Infertile couples often engage overseas surrogates, which increases the risk for legal and ethical complications. This book provides clinical guidance on the provision of gestational surrogacy on a worldwide basis, with brief summaries of the legal position within countries where it is offered. This volume provides a comprehensive overview of surrogacy for clinicians, counsellors, attorneys, legislators and anyone interested in reproductive health policy by filling an immediate niche as a resource for those interested in third-party reproductive treatments
Comment. No 'brownie points' for ill-conceived Donation Review
No full textA critical commentary of the Human Fertilisation and Embryology Authority's 'Donation Review' launched in January 2011
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
They Can't Have My Embryo: The Ethics of Conditional Embryo Donation
Full text linkThere are substantial numbers of frozen embryos in storage that will not be used by those who produced them for their own fertility treatment. One option for such embryos is to donate them to others to use in their fertility treatment. There has been considerable debate about how this process should be organized. In the US, there are embryo adoption programmes that mediate between those relinquishing embryos and potential recipients. This is a form of conditional embryo donation, where the relinquishing couple can choose the recipient of their embryo. This article examines the ethical debate over conditional embryo donation for family building and explores the question of whether those who have unused frozen embryos should be able to determine who receives their embryos. The main objections to conditional embryo donation are examined: first, the embryo is not a person and therefore such concern over the placement of an embryo is unwarranted; secondly, potential donors might impose morally problematic conditions on who should receive their embryo; and thirdly, there are practical difficulties regarding organizational arrangements and the associated costs involved. It will be concluded that these objections can be countered and that if people wish to donate and receive embryos in this way there is no ethical objection to them doing so
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
