Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Bioethical perspectives of the everyday living for people with dementia: from decision autonomy to caring for the future
Get PDFΗ άνοια θέτει μια πρόκληση για την ορθή κρίση και την αυτονομία των ατόμων, ενώ υποσκάπτει την ποιότητα ζωής τους. Τα ηθικά ζητήματα αντιμετωπίζονται από τα ίδια τα άτομα με άνοια, τους φροντιστές τους και τους παρόχους υγειονομικής περίθαλψης σε καθημερινή βάση. Αυτά εκτείνονται σε ένα ευρύ φάσμα, το οποίο περιλαμβάνει όχι μόνο τα σοβαρά ζητήματα για τις αποφάσεις στο τέλος της ζωής, αλλά και τα απλά καθημερινά προβλήματα, όπως η οδήγηση. Η διεπιστημονική προσέγγιση των βιοηθικών ζητημάτων αναδεικνύει την άνοια ως σημαντικό και πολύπλευρο κοινωνικό φαινόμενο. Οι αλλαγές στις γνωστικές ικανότητες και τις καθημερινές δραστηριότητες επηρεάζουν τις διαπροσωπικές αλληλεπιδράσεις και τις οικογενειακές σχέσεις. Οι ασθενείς, το περιβάλλον τους και οι κλινικοί ιατροί καλούνται σε ένα νέο πλαίσιο να συνεργάζονται για να λάβουν αποφάσεις σχετικά με τη διαγνωστική διαδικασία, την καθημερινή διαβίωση, τον συντονισμό της φροντίδας, τον εκ των προτέρων προγραμματισμό της ή τις παρεμβάσεις στο τέλος της ζωής. Οι στενές σχέσεις μεταξύ ηθικής και δικαίου είναι διαχρονικές, καθιστώντας απαραίτητη την παράλληλη μελέτη των ηθικών ζητημάτων με τη νομοθεσία.Dementia poses a challenge to individuals' good judgment and autonomy, while undermining their quality of life. Ethical issues are faced by people with dementia themselves, their carers and health care providers on a daily basis. Such aspects span a wide spectrum, including not only the serious issues of end-of-life decisions, but also simple everyday problems such as driving. The interdisciplinary approach to bioethical issues highlights dementia as an important and multifaceted social phenomenon. Changes in cognitive abilities and daily activities affect interpersonal interactions and family relationships. Patients, their social environment, and clinicians are called upon in a new context to work together towards decision making about the diagnostic process, daily living, care coordination, advance planning, or end-of-life interventions. The close relations between ethics and law are timeless, making it necessary to study ethical issues alongside legislation
Νευρολογικές συνέπειες των τρομοκρατικών επιθέσεων
No full textΥπόβαθρο: Οι τρομοκρατικές επιθέσεις είναι μια συνεχής παγκόσμια απειλή. Οι ιδιαιτερότητές τους απαιτούν συνεχή εκπαίδευση για όσους εμπλέκονται στην αντιμετώπιση των επιπτώσεών τους. Οι ιατροί κάθε ειδικότητας οφείλουν να είναι προετοιμασμένοι για εξειδικευμένη ανταπόκριση σε ανάλογες συνθήκες. Σκοπός: Η ανάδειξη των νευρολογικών επιπτώσεων των επιβεβαιωμένων και δυνητικών μέσων τρομοκρατίας. Μεθοδολογία: Η παρούσα εργασία διαρθρώνεται στο πλαίσιο Scoping Review. Τα λεπτομερή κριτήρια ένταξης και αποκλεισμού βιβλιογραφίας καθορίστηκαν με βάση το Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR). Αποτελέσματα: Η χρήση εκρηκτικών παρουσιάζει τραυματισμούς με ιδιαίτερο πρότυπο και νευρολογικό ενδιαφέρον. Ταυτόχρονα, χημικοί παράγοντες, με προεξάρχοντες τους οργανοφωσφορικούς, αλλά και βιολογικοί όπως βακτήρια, τοξίνες και ιοί, είναι πιθανοί νευρολογικοί κίνδυνοι. Οι επιθέσεις του παρελθόντος έχουν αρκετά να διδάξουν για σύνθετες επιπτώσεις στο νευρικό σύστημα. Συζήτηση: Το νευρικό σύστημα αποτελεί στόχο πολλών παραγόντων που σχετίζονται με τρομοκρατικές επιθέσεις. Από τα εκρηκτικά έως χημικούς και βιολογικούς παράγοντες αλλά και με τον κίνδυνο μιας ραδιολογικής απειλής, οι νευρολόγοι έρχονται αντιμέτωποι με ευρεία σειρά κλινικών προκλήσεων.Background: Terrorist attacks are an ongoing global threat. Their peculiarities require continuous training for those involved in dealing with their effects. Doctors of every specialty must be prepared for a specialized response to similar conditions. Objective: To highlight the neurological effects of confirmed and potential means of terrorism. Methodology: This thesis is structured in the framework of Scoping Review. Detailed literature inclusion and exclusion criteria were determined based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR). Results: The use of explosives presents injuries with a particular pattern and neurological interest. At the same time, chemical agents with organophosphates as a prominent factor, as well as biological agents such as bacteria, toxins, and viruses, pose possible neurological risks. Past attacks have much to teach about complex effects on the nervous system. Discussion: The nervous system is a target of many agents associated with terrorist attacks. From explosives to chemical and biological agents and the risk of a radiological threat, neurologists are faced with a wide range of clinical challenges

Get PDFDispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
