Mobile robotic telepresence and physical exercises : evaluating the acceptability of the technology and the feasibility of a teleexercise program for the older adults.
No full textDes interventions axées sur l’exercice physique permettent de soutenir un vieillissement en meilleure santé. L'engagement des aînés à ces programmes reste pourtant assez faible en raison d'obstacles environnementaux et personnels, tels que l'accès limité aux infrastructures, les difficultés de mobilité ou le manque de motivation. Pour répondre à ces défis, les technologies, comme les robots mobiles de téléprésence (MRP) peuvent être utilisées. Leur intégration dans la pratique quotidienne est encore limitée, et il n'est pas certain qu’ils seront bien acceptés par les aînés ou qu’ils permettront la faisabilité des programmes d'exercices. L'acceptabilité, définie comme la volonté d'utiliser une technologie est essentielle pour la faisabilité et l’efficacité des interventions. Le but de cette thèse était d’évaluer l’acceptabilité du MRP Cutii® (CareClever) pour ensuite proposer un programme en téléexercice aux personnes âgées.Cette thèse a été réalisée en collaboration avec le Cirris (Université Laval, Québec) et l’unité de recherche HAVAE(Université de Limoges, France). Le projet a été approuvé par le comité d’éthique du Centre intégré et universitaire de santé et des services sociaux de la Capitale-Nationale (# 2022-2449, RIS) (Québec, Canada). Le MRP Cutii® utilisé dans ces études vise à rompre l’isolement social des personnes âgées. Conçu comme un support de visioconférence mobile, il permet de suivre à distance de manière synchrone des programmes d’exercices physiques.Trois études sont présentées dans cette thèse. En se basant sur la Théorie unifiée de l'acceptation et de l'utilisation des technologies-2 (UTAUT2), l’étude 1 a permis d’évaluer l'acceptabilité a priori du MRP. L’étude 2 a permis d’évaluer l'acceptation située du MRP dans le cadre d'une intervention à distance auprès de 2 groupes de personnes (autonome ou semi-autonome). Ces 2 études ont été menées au Québec auprès de personnes âgées de plus de 65 ans vivant en résidence privée pour ainés. Une 3ème étude prévue en France visait à évaluer l'équivalence de deux groupes concernant l'équilibre suite à la réalisation d’un programme d’entrainement de 8 semaines proposée i) de manière synchrone par un MRP, ii) en présentiel. La faillite de l’entreprise CareClever a empêché sa réalisation, seul son protocole est présenté.Les résultats de l’étude 1 (n=19) révèlent que bien que les participants ont bien accueilli leur première expérience, leur intention d'utiliser les MRP à l'avenir reste faible, soulignant une faible acceptabilité a priori. L’étude 2 (n=21) a confirmé ces résultats après une utilisation prolongée (4 à 6 semaines) indiquant une faible acceptation située des MRP. Des réserves sont émises sur l'adéquation des MRP avec les besoins des personnes âgées qui semblent privilégier une aide fonctionnelle plutôt que sociale. Les MRP semblent avoir des avantages limités par rapport à d’autres technologies. En utilisant les critères de Thabane et al. (2010) l’étude 2, a montré la faisabilité du programme en téléexercice, soulignant l’engagement des participants et la sécurité des exercices. Des réserves sur l’utilisabilité et la fiabilité des MRP demeurent.Ce projet de doctorat a permis d'évaluer l'acceptabilité a priori et l’acceptation située du MRP Cutii® chez des personnes âgées vivant en résidence pour ainés. Plusieurs freins à l’acceptabilité des MRP sont identifiés : l'inadéquation entre les objectifs des MRP et les besoins des résidents, une comparaison défavorable avec d'autres technologies. Néanmoins, des preuves soutiennent la faisabilité des programmes en téléexercice proposé via les MRP Cutii®. L'efficacité du programme d’exercices physiques sur la condition physique doit être évaluer. Des recherches futures avec des échantillons plus larges et diversifiés sont nécessaires pour réévaluer la technologie en constante évolution et pour mesurer l'engagement à long terme des personnes âgées aux programme d’exercices physiques proposés via les MRP.Interventions focused on physical exercise help promote healthier aging. However, older adults' engagement in these programs remains relatively low due to environmental and personal barriers, such as limited access to infrastructure, mobility difficulties, or lack of motivation. To address these challenges, technologies like mobile robotic telepresence (MRP) can be used. Their integration into daily practice is still limited, and it is uncertain whether they will be well accepted by older adults or enable the feasibility of exercise programs. Acceptability, defined as the willingness to use a technology, is essential for the feasibility and effectiveness of interventions. The goal of this thesis was to evaluate the acceptability of the MRP Cutii® (CareClever) and then propose a remote exercise program for older adults.This thesis was carried out in collaboration with Cirris (Université Laval, Québec) and the HAVAE research unit (Université de Limoges, France). The project was approved by the ethics committee of the Centre intégré et universitaire de santé et des services sociaux de la Capitale-Nationale (# 2022-2449, RIS) (Québec, Canada). The MRP Cutii® used in these studies aims to break the social isolation of older adults. Designed as a mobile videoconferencing support, it allows remote, synchronous participation in physical exercise programs.Three studies are presented in this thesis. Based on the Unified Theory of Acceptance and Use of Technology-2 (UTAUT2), Study 1 evaluated the a priori acceptability of the MRP. Study 2 evaluated the situated acceptance of the MRP within the context of a remote intervention among two groups of individuals (autonomous or semi-autonomous). These two studies were conducted in Québec with participants aged over 65 living in private senior residences. A third study planned in France aimed to evaluate the equivalence of two groups concerning balance after completing an eight-week training program offered i) synchronously via MRP, ii) face-to-face. The bankruptcy of the CareClever company prevented its completion, and only its protocol is presented.The results of Study 1 (n=19) reveal that although participants responded positively to their first experience, their intention to use the MRP in the future remains low, highlighting a low a priori acceptability. Study 2 (n=21) confirmed these results after prolonged use (4 to 6 weeks), indicating low situated acceptance of the MRP. Reservations were expressed about the fit of the MRP with the needs of older adults, who seemed to prioritize functional over social assistance. The MRP appears to have limited advantages compared to other technologies. Using Thabane et al.’s (2010) criteria, Study 2 demonstrated the feasibility of the remote exercise program, emphasizing participant engagement and exercise safety. However, concerns about the usability and reliability of the MRP remain.This doctoral project evaluated the a priori acceptability and situated acceptance of the MRP Cutii® among older adults living in senior residences. Several barriers to the acceptability of the MRP were identified: the mismatch between the MRP’s objectives and the residents' needs, and unfavorable comparisons with other technologies. Nevertheless, evidence supports the feasibility of remote exercise programs offered via the MRP Cutii®. The effectiveness of the exercise program on physical condition remains to be assessed. Future research with larger and more diverse samples is needed to re-evaluate the constantly evolving technology and to measure the long-term engagement of older adults in exercise programs offered via the MRP
Comparison and validation of pressure and acceleration time-domain waveform models of a smart insole for accurate step count in healthy people
No full textSeveral studies have shown good accuracies for step count based on pressure signals of smart insoles in people walking at different speeds. Although smart insoles are often equipped with pressure sensors and accelerometer, no study has focused on comparing the accuracy of step count separately based on pressure and acceleration signals in healthy people. The objectives of this study were to design a waveform model of accelerometer and pressure sensors, and then compare with commercially well-known step count devices and validate these models using manual step counter for step count. Eight healthy participants (age: 39.8±17.56 years old) wore a pair of smart insoles, a GaitUp, and a StepWatchTM and performed the six-minute walking test at walking speeds from 1.62 to 2.22 m/s. Four pressure and one acceleration waveform models were designed and used for the detection of 341 to 412 steps. Accuracies ranged from 99.80%±0.60% to 99.97%±1.38% for right side, and from 99.67%±0.63% to 99.90%±0.05% for left side with pressure waveform models. In addition, the acceleration waveform model provided accuracies of 99.87%±2.49% and 99.84%±4.77% for right and left sides respectively. Step count accuracies using the GaitUp were 99.51%±2.06% for right side, and 99.51%±4.32% for left side. Finally, the StepWatchTM yielded step count accuracies of 99.31%±15.95% and 98.52%±28.06% for right and left sides respectively. These results suggested the smart insole with pressure and acceleration waveform models as more accurate than the StepWatchTM and the GaitUp for step count
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
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
