Development of a methodology to convert whole-blood donors to plasma donation in an anonymous, voluntary and non-remunerated system, using the theory of planned behavior and implementation intentions
No full textDepuis des décennies, l’engagement des populations dans le don de sang représente un enjeu sanitaire majeur dans le monde. Ces dernières années, l’augmentation forte des besoins en produits dérivés du plasma entraîne des difficultés pour les systèmes de collecte non-rémunéré, tels que l’Établissement Français du Sang, à assurer l’autosuffisance nationale. Cette thèse vise à mobiliser des connaissances et techniques issues des sciences humaines et sociales, plus spécifiquement issues de la psychologie sociale, pour développer des solutions appliquées permettant de mieux convertir les donneurs de sang au don de plasma. Pour ce faire, nous avons réalisé trois études au cours desquelles les motivations et freins au don de plasma de donneurs de sang étaient évalués. Une intervention construite autour de la théorie du comportement planifié et de l’implémentation d’intentions était testée dans les deux expérimentations suivantes. L’objectif de cette intervention était de réduire les freins au don, d’augmenter l’intention de donner, et de favoriser la conversion au don de plasma. Nos résultats montrent que les donneurs de sang perçoivent plus de freins au don de plasma qu’au don de sang, et que des interventions de communication centrées sur ces freins sont efficaces pour favoriser la conversion. Ces résultats nous permettent de mieux comprendre les déterminants de l’engagement des donneurs de sang dans le don de plasma, et d’identifier des solutions concrètes pour l’Établissement Français du Sang.For decades, engaging people in whole-blood donation has been a major worldwide public health issue. These last years, the strong increase of the demand of plasma-derived products has led non-remunerated collection establishments, such as the National French Blood Institute, to experience difficulties in achieving national self-sufficiency. This thesis aims to callup on knowledge and techniques from human sciences, more specifically from social psychology, to develop applied solutions that will bolster conversion of whole-blood donors to plasma donation. To do so, we conducted three studies in which we identified the main motivations and deterrents to plasma donation of whole-blood donor samples. An intervention based on the theory of planned behavior and implementation intentions techniques was evaluated in experiment 2 and 3. This intervention aimed at reducing deterrents to donation, increasing intention to donate, and facilitate conversion to plasma donation. Our results show that whole-blood donors perceive more deterrents to plasma donation than whole-blood donation, and that interventions based on these deterrents are more likely to facilitate conversion. These results give us a better understanding of the main determinants of commitment of whole-blood donors in plasma donation, and enable us to identify applied solutions for the National French Blood Institut
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
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
The application of our evaluation and co-design system based on UTAUT 2 with seniors allowed a significant increase in the intention to use the two gerontechnologies studied
No full textL'objectif de ce travail de thèse est de concevoir une démarche d'intervention afin d'accompagner les porteurs de projet de la Silver économie dans le développement de technologies plus acceptables pour accompagner le bien vieillir des personnes âgées au sein de leur domicile. Notre approche scientifique repose sur une analyse des méthodologies de co-conception en living lab (Dubé et al., 2014 ; Labarthe et Francou, 2014) et des méthodologies d'évaluation de l'acceptabilité sociale (Fishbein et Ajzen, 1975 ; Venkatesh et al., 2003). Ainsi, l'UTAUT 2 (Venkatesh et al., 2012) et la grille de persuasion technologique (Nemery et al., 2011) nous sont apparu comme les modèles d'évaluation et de co-conception les plus adaptés à la spécificité des gérontechnologies et des contraintes de notre contexte d'étude. L'application de notre dispositif d'évaluation et de co-conception avec les seniors a permis une augmentation significative de l'intention d'usage des deux gérontechnologies étudiées. Nous avons observé une augmentation de 10,87% de l'intention d'usage de la première gérontechnologie et de 32,03% de la seconde gérontechnologie. Ce dispositif s'est avéré plus efficace en ce qui concerne l'amélioration de facteurs technologiques tels que l'effort attendu (+35,36%) et la motivation hédonique (+76,44%) que de facteurs individuels liés à des représentations subjectives comme la performance attendue (+9,78%) et l'influence sociale (+10,38%) de la gérontechnologie.The objective of this thesis work is to design an intervention process to support Silver Economy project leaders in the development of more acceptable technologies to support the aging well of the elderly in their homes. Our scientific approach is based on an analysis of living lab co-design methodologies (Dubé et al., 2014 and Labarthe and Francou, 2014) and assessment methodologies of social acceptability (Fishbein & Ajzen, 1975 ; Venkatesh and al., 2003). Thus, we selected UTAUT 2 (Venkatesh et al., 2012) and the technological persuasion grid (Nemery et al., 2011) as our assessment and co-design models. The application of our evaluation and co-design system with seniors allowed a significant increase in the intention to use the two gerontechnologies studied. We observed an increase of 10.87% the intention to use the first gerontechnology and 32.03% of the second gerontechnology. This device proved to be more effective in terms of improving technological factors such as expected effort (+ 35.36%) and hedonic motivation (+ 76.44%) than individual factors linked to subjective representations in particular of the expected performance (+ 9.78%) and the social influence (+ 10.38%) of gerontechnology
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
