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
Selective antagonism of sigma-1 receptors as a new strategy for pain treatment : behavioural and neurochemical studies
Get PDFIn the present thesis, and in the context of the Sigma-1 receptor (σ1R) research project running at the pharmaceutical company ESTEVE, we addressed, at the preclinical level, the role played by selective σ1R antagonism/blockade in nociception in order to ascertain the therapeutic interest of σ1R antagonists in pain treatment. Taking advantage of using selective σ1R pharmacological tools and the in vivo microdialysis technique, the mechanism and the site of action of selective antagonism of σ1R were investigated in pain conditions involving sensitization (formalin model) as well as in acute thermal pain (tail-flick test) to look at the modulation of opioid-induced efficacy and safety-related outcomes. The results of this thesis provide new knowledge about σ1R as a pain target suitable for therapeutic intervention to get analgesia and support the use of σ1R antagonists as opioid adjuvants to treat pain conditionsEn aquesta tesi, i en context amb el projecte de recerca sobre el receptor Sigma-1 (σ1R) que té lloc a l’empresa farmacèutica ESTEVE, hem estudiat, a nivell preclínic, el paper de l’antagonisme/bloqueig selectiu del σ1R en nocicepció, per tal de determinar l’interès terapèutic dels antagonistes del σ1R per al tractament del dolor. Mitjançant l’ús d’eines farmacològiques selectives per al σ1R i de la tècnica de microdiàlisi in vivo, el mecanisme i el lloc d’acció de l’antagonisme selectiu del σ1R van ser estudiats en condicions de dolor que impliquen sensibilització (model de la formalina) així com en dolor agut (test del tail-flick) on vam analitzar la modulació de l’eficàcia produïda pels opioides i paràmetres de seguretat. Els resultats d’aquesta tesi aporten nou coneixement sobre el σ1R com a diana terapèutica idònia per obtenir analgèsia i reafirmen l’ús d’antagonistes del σ1R com a adjuvants als opioides per al tractament del dolor.Programa de doctorat en Biomedicin
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
Dispelling 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
Maneig del pacient crític sotmès a teràpia ecmo: el rol de la infermera ECMO Specialist
Get PDFTreball de fi de grau – Curs 2024-2025Introducció: La demanda de teràpia ECMO ha augmentat en els últims anys. En tractar-se d’una tècnica complexa cal tenir personal sanitari format en el seu maneig per assegurar el correcte funcionament d’aquesta. Existeix una figura infermera capacitada per assumir aquesta funció, però el seu rol no està reconegut. Objectius: Descriure les cures infermeres que requereixen els pacients sotmesos a teràpia amb ECMO, identificar el rol de la infermera ECMO Specialist i conèixer quines competències són necessàries per ser ECMO Specialist. Metodologia: Revisió de la literatura dels últims 10 anys a les bases de dades PubMed, CINAHL, Cochrane, Cuiden, Cuidatge, Dialnet i Epistemonikos. [...
Diseño de una aplicación móvil de soporte para mejorar la atención a los pacientes con Enfermedad Renal Crónica Avanzada en la consulta de la enfermera ERCA
Get PDFTreball de fi de grau – Curs 2023-2024Introducción: La enfermedad renal crónica produce un impacto significativo en la vida de las personas que la padecen. En el caso de las enfermedades renales crónicas, tanto los pacientes como sus familiares o cuidadores/as deben ser conocedores de la importancia que tienen, por ejemplo, los tratamientos para la sustitución renal existentes o bien, comprender que ciertas situaciones pueden ser perjudiciales para la misma. La enfermera ERCA se encarga de abordar las situaciones de manera individualizada para poder así mantener un seguimiento de los pacientes en las consultas, fomentando el autocuidado, la autonomía y el empoderamiento, consiguiendo así que sean capaces de tomar decisiones informadas y participen de manera activa en el manejo de la enfermedad.
