Les recherches en Sciences de Gestion et Sciences des Systèmes d'Information ont proposé diverses analyses des bénéfices des réseaux sociaux et de leurs processus d’adoption. Toutefois, les usages des réseaux sociaux sont multiples et chacun mériterait d’être approfondi. En particulier, la curation digitale est une pratique qui s’impose comme un objet de recherche particulièrement pertinent. Il propose une nouvelle utilisation des réseaux sociaux numériques, potentiellement bénéfique à l’entreprise. Ainsi, il est proposé de rapprocher les notions de curation, réseaux sociaux numériques et connaissance organisationnelle au travers de la problématique suivante : en quoi l’usage professionnel de la curation sur les réseaux sociaux permet-il d’améliorer les connaissances organisationnelles ? Pour y répondre, cette question a été articulée en trois sous-problématiques, permettant trois différents niveaux d’analyse. La première aborde les facteurs influençant l’adoption de la pratique de curation par l’individu ; la deuxième propose d’analyser l’intérêt des réseaux sociaux en tant qu’outil de support pour effectuer la curation de contenu ; la dernière associe les deux notions de curation et réseaux sociaux dans le cadre organisationnel, afin d’en comprendre ses bénéfices. Les cadres théoriques de la richesse des médias, la présence sociale, l'UTAUT et le model SLAM de l'apprentissage organisationnel ont été mobilisés à cet effet. Un questionnaire récoltant 841 réponses et 14 entretiens semi-directifs ont permis de confirmer la présence d'un lien positif entre l'adoption de l'usage de la curation sur les réseaux sociaux et l'amélioration des connaissances individuelles et collectives. Afin qu’elles puissent être converties en connaissances organisationnelles, il a été prouvé que les flux informationnels de l'entreprise doivent être alignés avec les différents niveaux de stock de connaissances. / Research in Management Science and Information Systems has proposed a series of work centered around the benefits of social networks for individuals and the adoption process that it entails. However, social network uses are numerous and each of them deserve in-depth studies. Specifically, the practice of content curation becomes truly relevant in a context of digital transformation. It proposes a new social network use that can benefit the organization. Thereby, the research opts to gather the concept of social network, curation and organizational knowledge through the following question: how does profesionnal content curation on social network participate to organizational knowledge ? This question has been sub-divided into three questions, allowing different multi-level analysis. The first one questions the influencing factors of social network curation for individuals ; the second one interrogates the benefit of using social network tool to operate content curation ; the third one combines both concepts in an organizational context with the aim of clarifying its benefits. Media Richess Theory, Social Presence Theory, UTAUT and SLAM Framework has been used to bring an answer to them. 841 questionary respondants along with 14 semi-directional interviews sufficed to confirm positive link betwen the adoption of social network curation and improvement of individual and collective knowledge. To reach organizational knowledge, the research demonstrates that informatio flows and the different stocks of knowledge need to be aligned.

<p>The purpose of this research was to investigate how work orientation (job, career, and calling) affects the professional life of leaders; and how leaders perceive their work regarding these three dimensions. In addition, this study aimed to relate work orientation to performance. Also, phenomenology approach allowed a deep investigation of the experience of leaders with regard to their work.</p><p> For this purpose, two surveys were used; one was on work orientation and the other on performance. After completion of the surveys, six participants were invited to participate in an in-depth interview. The participants were aligned with the calling orientation and had a high performance at work. They described their work as integrated into their lives, involving their families in decisions, helping people, and desiring to make a difference in this world. Also, the findings showed that people who live a calling feel that work and life have intertwined meanings. The motivation, well-being, connection with an organization, engagement with work, and having a purpose were factors that had significance for those who perceive work as a calling. The main results were that the participants faced new challenges, built new meanings and understandings about work during their careers. Each experience helped them to improve the next, while also improving their performance. The relationship between these factors revealed a cycle of meanings. The cycle represents the evolution of the creation of new meanings which defines how people perceive their work and how that influences performance. Furthermore, this study showed that it is possible to change the perception of work through goals, achievement, working context, the adversities faced, stages of life, and the work environment. All of these lead to new meanings and becoming aligned to different dimensions of work orientation. </p><p><br></p><p><br></p>

<p>The technology availability and hype of virtual reality has intersected as of 2016, bringing a lot of attention to virtual reality (VR) games. The research into this technology has been ongoing since its early exploration in the 1970’s. Methods have been created to try to understand and predict what causes phenomena such as motion and simulator sickness in the human computer interaction devices. Heuristics have been developed to aid the design these applications and to avoid such discomforting circumstances. Concepts and their continued exploration have been growing to improve the experience of virtual reality technology and continue the expanding imagination of what is capable with this technology. All the tools are available to create highly immersive virtual experiences, but it is up to the interpretant, the user to decide how believable, immersive and enjoyable these experiences are. By conducting an interview study on a part of the VR gaming community, more can be understood about the success and failure of immersive design by exploring the experiences of certain highly immersive games. This study takes the opportunity to listen to gamers as a means of highlighting significant key challenges and characteristics creating immersive VR games. By evaluating transcripts via thematic analysis, themes were created to understand and categorize the various aspects that are most important to the immersion and embodiment in VR games. This study and themes drawn from it reflect on the experiences and feelings of experienced VR gamers in the context of role-playing games.</p>

<p dir="ltr">In this paper, we address the gap in people's perceptions of using artificial intelligence (AI) in animation, mainly focusing on AI-based motion capture. We aimed to understand how individuals perceived animations created by AI, manual, and AI with manual cleanup methods. We presented our participants with short, full-body animation clips created using the three methods. Participants rated the appeal and naturalness of the animations, and we asked them to discern the creation method. Results revealed differences in perceived appeal and naturalness between manually created animations and those generated through AI-involved methods, with manual animations consistently rated higher. However, participants were unable to discern creation methods regardless of animation experience level, demonstrating an accuracy equivalent to random guessing. Moreover, the qualitative analysis highlighted diverse perspectives with negative and positive views on AI use, with the most mentioned theme being the importance of quality regardless of creation method. The overwhelming majority of participants asserted that the degree of automatization would influence their perceived value and effort put into an animation. Still, this group didn't show divergent ratings, nor did it affect their overall agreeableness towards using AI in creative fields. This study contributes valuable insights into the intersection of animation and AI, informing creators about the effect of different creation methods on audience perceptions.</p>

<p dir="ltr">Teletaction, the transmission of tactile feedback or touch, is a crucial aspect in the</p><p dir="ltr">field of teleoperation. High-quality teletaction feedback allows users to remotely manipulate</p><p dir="ltr">objects and increase the quality of the human-machine interface between the operator and</p><p dir="ltr">the robot, making complex manipulation tasks possible.

<p dir="ltr">Many tasks require processing, filtering, and responding to information from multiple sensory modalities. Crossmodal interactions are common and visual dominance often arises with incongruent sensory information. Past studies have shown that visual dominance tends to be strong in spatial tasks. Experiments in a crossmodal attention switching paradigm with physical-spatial stimuli (e.g., stimuli in left and right locations) have demonstrated a robust visual dominance congruence pattern with conflicting visual-spatial information impairing responses to auditory-spatial stimuli, but conflicting auditory-spatial information having less impact on visual-spatial processing. Strikingly, this pattern does not occur with verbal-spatial stimuli (e.g., the words LEFT and RIGHT as stimuli). In the present study, experiments were conducted to systematically examine the occurrence and underlying basis of this distinction. Participants were presented with either verbal-spatial or physical-spatial stimuli, simultaneously in the visual and auditory modalities, and were to selectively attend and respond to the location of the cued modality. An initial experiment replicated previously reported effects, with similar patterns of crossmodal congruence effects for visual and auditory verbal-spatial stimuli. Three further experiments directly compared crossmodal congruence patterns for physical-spatial and verbal-spatial stimuli across varying attentional conditions. Intermixing verbal and physical spatial stimulus sets did not meaningfully alter the distinct congruence patterns compared to when the sets were blocked, and biasing attention to verbal-spatial processing amplified the modality-congruence interaction for physical-spatial stimuli. Together, the consistent findings of the modality-congruence interaction showing visual dominance for physical-spatial stimuli but not for verbal-spatial stimuli suggests that the effect is driven by the particular spatial sets based on their sensory properties rather than endogenous attentional mechanisms.</p>

<div>Vehicle automation is developing at a rapid rate worldwide. However, even lower levels of automation, such as SAE Level-1, are expected to reduce drivers’ workload by controlling either speed or lane position. At the same time, however, drivers’ engagement in secondary tasks may make up for this difference in workload displaced by automation. Previous research has investigated the effects of adaptive cruise control (ACC) on driving performance and workload, but little attention has been devoted to Lane Keeping Systems (LKS). In addition, the influence of secondary cognitive tasks on Level-1 driving performance is also not well understood.</div><div><br></div><div>The first goal of this thesis study was to examine the effects of secondary cognitive tasks and driving condition on driving performance. The second goal was to examine the effects of secondary cognitive tasks and driving condition on heart rate related measurements that reflect changes in workload. Both a novel nano-sensor and a commercial ECG sensor were used to measure heart rate. Thus, the third goal was to compare the capability of a nano-sensor in detecting changes in heart rate and heart rate variability with a commercially available ECG sensor. Twenty-five participants drove a simulated vehicle in manual, ACC and LKS driving conditions, while performing a secondary cognitive (N-back) task with varying levels of difficulty.</div><div><br></div><div>Results showed that more difficult cognitive secondary tasks were beneficial to driving performance in that a lower standard deviation of lane departure (SDLD) and a lower standard deviation of vehicle speed (SDVS) were both observed. Heart rate and NASA-TLX workload scores were significantly higher in the most difficult secondary task and in the manual driving conditions. However, heart rate variability measures (SDNN, RMSSD, pNN50, LF Power and HF Power) indicated lower variability under more difficult secondary tasks. This thesis suggests that nanotechnological devices may serve as a potential alternative to other heart rate measuring technology. Limitations in detecting minor heart rate changes between different driving conditions and in heart rate variability measuring were also acknowledged.</div>

This study presents an analysis of human encounter with place. It examines the personal and cultural importance of an attachment to place, focusing on the reciprocal relationship between cultural heritage and a sense of place. Place is constructed out of mutual meanings between people and their environment. The study begins with an indepth look at the theory of place. In a series of heritage management case studies, the theory is applied in order to illustrate how meanings of place may be expressed. Place as a normative concept provides a role for resource managers in finding the meanings people associate with places, and in nurturing and enhancing these meanings. This involves the recognition of different values and 'stories' that are associated with place. Recognising these differences helps shift resource management away from the simplicity of grand narratives and totalizing discourses, towards a respect for intangible and multiple meanings in place. To a certain extent an understanding of place is already informing both natural and cultural management decisions in New Zealand, although this may not be explicitly recognised. To approach cultural heritage management from the perspective of place, however, challenges the current directions that heritage management is taking in this country. The study proposes a way of taking up that challenge, and concludes that the importance of place should not be overlooked.

<div>The link between volatile organic compounds (VOCs) from breath and various diseases and specific conditions has been identified since long by the researchers. Canine studies and breath sample analysis on Gas chromatography/ Mass Spectroscopy has proven that there are VOCs in the breath that can detect and potentially predict hypoglycemia. This project aims at developing a smart nanosensor system to detect hypoglycemia from human breath. The sensor system comprises of 1-Mercapto-(triethylene glycol) methyl ether functionalized goldnanoparticle (EGNPs) sensors coated with polyetherimide (PEI) and poly(vinylidene fluoride -hexafluoropropylene) (PVDF-HFP) and polymer composite sensor made from PVDF-HFP-Carbon Black (PVDF-HFP/CB), an interface circuit that performs signal conditioning and amplification, and a microcontroller with Bluetooth Low Energy (BLE) to control the interface circuit and communicate with an external personal digital assistant. The sensors were fabricated and tested with 5 VOCs in dry air and simulated breath (mixture of air, small portion of acetone, ethanol at high humidity) to investigate sensitivity and selectivity. The name of the VOCs is not disclosed herein but these VOCs have been identified in breath and are identified as potential biomarkers for other diseases as well. </div><div> </div><div> The sensor hydrophobicity has been studied using contact angle measurement. The GNPs size was verified using Ultra-Violent-Visible (UV-VIS) Spectroscopy. Field Emission Scanning Electron Microscope (FESEM) image is used to show GNPs embedded in the polymer film. The sensors sensitivity increases by more than 400% in an environment with relative humidity (RH) of 93% and the sensors show selectivity towards VOCs of interest. The interface circuit was designed on Eagle PCB and was fabricated using a two-layer PCB. The fabricated interface circuit was simulated with variable resistance and was verified with experiments. The system is also tested at different power source voltages and it was found that the system performance is optimum at more than 5 volts. The sensor fabrication, testing methods, and results are presented and discussed along with interface circuit design, fabrication, and characterization.</div>
