Gestazione per altri: corpi riproduttivi tra biocapitale e biodiritto
Full text linkInteraction between neoliberal economy and medical biotechnologies brought about a new formulation of the connection between feminine generative potential and value production. In this context, it is increasingly difficult to use the traditional tools of biolaw to cope with the problems that biocapital has raised. With a focus on surrogacy, the essay addresses two issues that need to be investigated and rethought in this new scenario: the exploitation/commodification of the human biological material and the safeguard and extension of reproductive self-determination
Sfide etiche e prospettive regolamentari degli organoidi a partire dai risultati di un Deliberative Workshop
Full text linkL’articolo esplora alcune delle questioni che emergono rispetto all’utilizzo degli organoidi in ambito clinico e di ricerca. Dopo aver introdotto il tema dell’utilizzo di strumenti di partecipazione democratica in ambito biotecnologico, il testo affronta alcune delle principali questioni bioetiche e biogiuridiche che riguardano gli organoidi attraverso la discussione dei risultati di un Deliberative Workshop svolto nell’ambito del progetto Hybrida – Embedding a comprehensive ethical dimension in organoid-based research and resulting technologies
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
Gestazione per altri in Messico: ricostruzione, ratio e problematiche degli attuali scenari normativi
No full textLa gestazione per altri (GPA) è una tecnica di fecondazione assistita che prevede la partecipazione oltre alla coppia di genitori intenzionali – che avranno la responsabilità genitoriale del nascituro – anche di una donna terza, che mette a disposizione il proprio utero e in alcuni casi anche il proprio ovulo per portare avanti la gravidanza, gratuitamente o a titolo oneroso, con il fine di consegnare al termine il bambino alla coppia. La possibilità di avvalersi di tale ipotesi riproduttiva ha sollevato numerose problematiche, la maggior parte delle quali non possono essere ancora considerate risolte o superate. Una di queste è relativa alla difficile individuazione di riferimenti teorici o normativi che permettano di raggiungere un punto di equilibrio tra mercificazione del corpo e autodeterminazione della donna. Questa difficoltà teorica si relaziona e viene acuita dai risvolti pratici che la realizzazione della tecnica produce, laddove mette in relazione gruppi sociali provenienti da contesti culturali e socio-economici diversi. Sorgono poi difficoltà legate ai meccanismi di riconoscimento della filiazione e alle ripercussioni sul nato, difficoltà che mettono in crisi il modello di famiglia eterosessuale e nucleare.Surrogacy is a reproductive practice whose regulation presents numerous inhomogeneities on a global level. The international scenario is constantly changing and the legal reforms are reshaping the flows of money and people mobilized in an ever increasing measure. After India in 2012 and Thailand in 2014 - countries where the gestational market had been concentrated until then - began a process of restrictive regulation, reproductive tourism began to flow towards Mexico. The aim of the paper is to reflect on the issue of surrogacy - in relation to which the transnational dimension has an important role - starting from the legislative choices of the Mexican states. In particular: the legislation of Querétaro, which banned the practice, of Tabasco which legalized it and finally the draft law of Mexico City
