Rachats d’actions annoncés versus rachats réalisés:une analyse du découplage sur le marché français - Announced share repurchase versus repurchase sh…

2011

(VF)Notre analyse originale porte sur la pertinence des explications des rachats d’actions en confrontant les motivations des rachats annoncés au faible taux de rachats effectifs mesuré sur le marché français. Nous mobilisons les principales explications théoriques des rachats d’actions et nous proposons une étude empirique de plusieurs centaines de programmes de rachats afin de justifier l’intention volontaire des dirigeants de ne pas engager des rachats importants en dépit de ceux annoncés provoquant ainsi un découplage. Nous montrons que certaines entreprises ont une probabilité plus élevée de provoquer ce découplage en rachetant plus faiblement leurs propres actions. Ce sont les entrepr…

Mechatronic Design of a Four-Wheel drive mobile robot and differential steering

2021

This paper presents, the development of an autonomous mobile robot with a four-wheel drive and differential locomotion. The mobile robot was developed in the Machines and Industrial Equipment Department from the Engineering Faculty of Sibiu. The main purpose of developing this type of mobile platform was the ability to transport different types of cargo either in industrial spaces or on rough terrain. Another important objective was that this platform could be driven in confined or tight spaces where a high degree of manoeuvrability is necessary. The great advantage of this type of mobile platform is the ability to navigate through narrow spaces due to the type of locomotion implemented. Th…

Dynamic of Components Leachate from Experimental Fertilizers in Leaching Test

2018

Organic matter contained in the waste of food industry or occurring in the households, in the absence of contamination with other kind of waste, may be used to create a “fertiliser”, which could be even reused in the organic production of arable crops. Particular attention is drawn to the fertilisers which may be applied in the case of amateur cultivation of pot plants and in the allotment gardens. The paper presents the results of research regarding the dynamics of the release of nutrients from tablets created with the help of encapsulation of the mixture manufactured from solvent extraction waste of coffee (SCG), modified by the ash obtained from low temperature burning of biomass. In thi…

Nutritional and microbiological quality of tiger nut tubers (Cyperus esculentus), derived plant-based and lactic fermented beverages

2018

International audience; Tiger nut (Cyperus esculentus) is a tuber that can be consumed raw or processed into beverages. Its nutritional composition shows a high content of lipid and dietary fiber, close to those of nuts, and a high content of starch, like in other tubers. Tiger nuts also contain high levels of phosphorus, calcium, and phenolic compounds, which contribute to their antioxidant activity. From those characteristics, tiger nuts and derived beverages are particularly relevant to limit food insecurity in regions where the plant can grow. In Europe and United States, the tiger nut derived beverages are of high interest as alternatives to milk and for gluten-free diets. Fermentation…

Dual Perspectives on the Role of Artificially Intelligent Robotic Virtual Agents in the Tourism, Travel and Hospitality Industries

2018

Robotics and artificial intelligence are challenging extant business services and fundamentally impacting business relationships and processes. While studies have elaborately investigated social robotic interactions in medical and health-related domains, studies are limited on artificially intelligent robotic virtual agents (AIRVA) and their impacts on consumer behavior in tourism and hospitality services. Building on the theories of user experience (UX), user interface (UI) and customer experience, this study conceptually examines the dual-value effects of AIRVA to the customer and the firm. It analyzes the customer journey and highlights critical touchpoints AIRVA deepens the customer exp…

Reparative giant cell granuloma in a pediatric patient

2007

Reparative giant cell granulomas are benign, infrequent tumors, of non-odontogenic origin, that develop at central or peripheral level. Peripherally located lesions are frequently denominated ‘giant cell epulis’, and never correspond to true neoplasia, but rather to inflammatory reactions secondary to another lesion (hemorrhage, etc.). It should be taken into account, that in general, head and neck tumors of infancy usually demonstrate an atypical biological behaviour. Furthermore, the anatomicopathologic diagnosis is often compromised in this type of lesion. We present the case of a 6-year-old boy, who, three weeks after suffering a slight facial trauma, developed a painless, exophytic swe…

2019

Background Health apps for the screening and diagnosis of mental disorders have emerged in recent years on various levels (eg, patients, practitioners, and public health system). However, the diagnostic quality of these apps has not been (sufficiently) tested so far. Objective The objective of this pilot study was to investigate the diagnostic quality of a health app for a broad spectrum of mental disorders and its dependency on expert knowledge. Methods Two psychotherapists, two psychology students, and two laypersons each read 20 case vignettes with a broad spectrum of mental disorders. They used a health app (Ada—Your Health Guide) to get a diagnosis by entering the symptoms. Interrater…

“Ihmisiltä poissa” – away from people : language learning spaces in Finnish as a foreign language students’ chat during the covid-19 pandemic

2020

Smart phones enable learners to practice language use in different spaces and environments beyond the classroom. Finnish language students in two North American universities participated in a collaborative chat project as part of their second-year language course. In this article we analyze how students' chat entries reflected their learning in different domestic spaces during the global covid-19 pandemic in spring 2020. nonPeerReviewed
