    La normativa sulla destinazione del corpo allo studio e alla ricerca: una riflessione multidisciplinare sulle questioni ancora aperte

    No full text
    Law No. 10/2020, supplemented by the regulation established by Presidential Decree No. 47/2023, regulates whole-body donation for education, training and scientific research. This paper aims to analyze, with an interdisciplinary approach, the critical issues and gaps in the legislation that hinder its full implementation. Particular attention will be paid to aspects related to self-determination, information, protection of anonymity and the restitution of the body

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    Exosomal HSP60 levels and related miRNAs in brain tumors

    In cancer, Extracellular Vesicles (EVs), such as exosomes, contribute to tumor progression by regulating local and systemic parameters [1,2]. Since exosomes are released into body fluids, they may be used in nanomedicine as a valuable source of diagnostic biomarkers [3]. The prognosis of brain tumors is poor even after surgical resection followed by post-operatory chemo- and radio-therapies and it is cogent to find innovative treatments. The discovery that molecular chaperones can be determinant factors in tumorigenesis and the increasing understanding of exosomes, particularly in what refers to their release by tumor cells and contents, including chaperones and miRNA, provide elements to develop novel treatment strategies and means [4]. We measured the chaperone HSP60 and related miRNAs in primary brain tumors and peritumoral cells in vivo to determine levels and distribution. In addition, the presence and levels of HSP60 and miRNAs involved in its regulation were investigated in blood exosomes isolated from tumor patients before and after ablative surgery. Blood and pathological tissue samples were taken on the surgery day, blood was collected at one week, one month, and three months after surgery, and exosomes were isolated. The results revealed distinctive changes in the levels of miRNAs involved in HSP60 regulation in brain tumors, pointing to their potential as biomarkers for diagnosis and patient monitoring during treatment.

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    We 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 text
    We 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
