Test genetici di paternità in gravidanza : una scelta oppure un obbligo per l’operatore?
No full textThe rapid development of molecular diagnostic techniques in the last twenty years has
been followed by an ethical and regulatory adjustment which turned out to be difficult
and complex.
At the same time the media contribute to convey to the public the idea of a virtual absence
of limits, especially when dealing with genetic investigations, which often leads to an
unconscious violation of the same regulations. However it is not uncommon to observe
that these rules are sometimes violated with full consciousness.
This manuscript will analyse the issue of genetic paternity testing performed during
pregnancy in the light of the Italian legislation.
This study does not cover a full revision of the international legislation, but it could
become a starting point in order to discuss an issue which is currently credited with only
marginal consideration.
After reviewing the main analytical techniques and the legal status of the embryo, the
Authors revised the legal framework and the principles of the medical code of conduct
regarding genetic discrimination in relation to the Law n. 194/1978 (the Italian law
governing the voluntary termination of pregnancy in some specific situations).
The main point to consider is whether DNA paternity tests are legally allowed during
pregnancy.
In either case there are significant legal and ethical implications for the health care
professional when asked for prenatal paternity testing.
From this study emerges the need for a legal clarification aimed at standardising the
rules, avoiding arbitrary decisions
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Integration of the AmpFlSTR Identifiler PCR Amplification Kit with SRY-specific primers for gender identification
No full textDropout of the amelogenin Y-specific allele due to an interstitial deletion of the Yp involving the amelogenin Y locus (AMELY) can cause misidentification of sex genotype with potentially serious consequences in personal identification processes and criminal investigations. Inclusion of additional sex-defining markers in forensic DNA typing kits is therefore advisable. In this study, the co-amplification of the sex-determining region Y (SRY) gene and 16 STR loci included in the AmpFlSTR Identifiler PCR Amplification Kit was evaluated. Combination of SRY and Identifiler primers did not compromise the amplification outcome and generated a 90 bp male-specific SRY fragment, showing a reproducible peak height ratio in comparison with the AMELY peak. The SRY peak was detectable in presence of amounts of template DNA as low as 125 pg, and in mixed samples with a male/female DNA ratio of 1:100
