Réalités (ou apparences ?) de l'hyperréalité : une application au cas du tourisme de loisirs

2005

Although hyperreality is not a subject commonly studied in marketing, it characterizes an increasing number of leisure and tourist places. In this article, we build a theoretical model to have a better understanding of this phenomenon in order to define it. This model as well as a study of leisure tourist universes help us to identify the attributes and commercial strategies that are used to create a hyperreal environment. We also explore the strategic opportunities and threats associated with developing hyperreality on commercial grounds.

Drivers’ experiences during floods: Investigating the psychological influences underpinning decisions to avoid driving through floodwater

2018

Abstract A major risk factor for many flood-related drownings is driving through floodwater. We aimed to understand Australian drivers’ experiences and beliefs with respect to avoid driving through floodwater using the theory of planned behaviour as a framework. Study 1 (N = 23) used a qualitative design to gain an in-depth understanding of individuals’ experiences with driving through floodwater. Study 2 (N = 157) used a survey-based design to identify the factors related to this behaviour including knowledge, beliefs, and social-cognitive factors. In Study 1, drivers identified a range of advantages (e.g., didn’t damage car), disadvantages (e.g., inconvenient, but not so terrible), barrie…

Exergoeconomics as a Cost-Accounting Method in Thermal Grids with the Presence of Renewable Energy Producers

2022

Thermal grids are efficient, reliable, and sustainable technologies for satisfying the thermal demands of buildings. The capability to operate at a low temperature allows not only for the integration of heat produced by renewable energy sources but also for the storage of surplus electricity from the grid via “power to heat” technologies. Besides, in the future, heat consumers are expected to behave increasingly as “prosumers”, supplying in some periods heat produced by renewable energy plants on site. In this scenario, it is important to propose a method for the cost allocation among producers connected to the grid. In this regard, this paper proposes Exergoeconomic…

Formation structure of optimality by thermoeconomics: disassembling thermodynamic and external influences in energy systems’ design

2009

In this paper an original thermoeconomic approach for the optimization of complex energy systems is presented, based on a revitalized concept of “scope”, and therefore indicated as Scope Oriented Thermoeconomics (SOT). In plants including dissipative components, it allows to formulate non-arbitrary allocation criteria as concerns marginal costs; consequently, the optimization process is disassembled to recognize the Formation Structure of Optimality, i.e. the specific influences of thermodynamic and economic parameters in the path toward the optimal design. The method is applied to a very didascalic example, that is the optimization of the condensation temperature in a vapour compression ch…

The new face of university–business cooperation in Finland

2016

This paper analyses the development of university-business cooperation (UBC) in Finland in the context of the University Reform Act of 2009, drawing on the experience of four universities: Aalto University, University of Jyvaskyla, University of Turku, and Lappeenranta University of Technology. Six UBC dimensions are examined: institutional context, stakeholders, motivations, facilitators/inhibitors, benefits, and drawbacks. We find that UBC, while a relatively recent process, is growing fast in dynamic local innovation and entrepreneurship ecosystems. The University Act of 2009 had an uneven effect on the six UBC dimensions, with the most visible impact being manifested on motivations. Aal…

Séries temporelles et flou

1982

La compréhension de la nature du temps, et de son écoulement, est un problème qui a toujours préoccupé les hommes L'idée que l'on se fait du temps est elle-même discutable et discutée, et pas seulement par les philosophes. Tout agent, dans l'activité qu'il déploie est amené à se poser, même implicitement, cette question. En effet, le temps nous est compté. Toute action doit le prendre en considération. La valeur des produits humains en dépend. Il faut toujours ramener une production, voire même une consommation, au temps qu'il a fallu pour la réaliser. Nul n'y échappe, ni dans ses loisirs, ni dans son travail. Mais c'est dans ce dernier que les instruments de mesure qui introduisant le temp…

About the problems caused by the Gini and Kakwani index of inequality measurement

1997

On fait le point sur les faiblesses des indices de Gini et de Kakwani lorsque la dominance entre distributions n’est pas garantie : à un même Gini peuvent correspondre plusieurs distributions différentes et à une même valeur du Kakwani peuvent correspondre une infinité de couples d’ indices de Gini. On propose alors d ’approximer la courbe de Lorenz typiquement en deux ou trois parties linéaires, puis de décrire la position de son coude ou de ses deux coudes par deux ou quatre nombres qui suffisent caractériser complètement sa forme et la catégorie à laquelle elle appartient. Une procédure de choix entre distributions est proposée, basée sur une application du maximin : entre deux distribut…

Utilisation des critères non financiers pour évaluer ou piloter la performance : analyse théorique

2005

The determinants which explain the use of non-financial measures in order to evaluate or drive the performance belong to disciplinary (contractual) and knowledge-based approaches. The aim of this paper is to propose a theoretical analysis of these explanations. For the disciplinary view, we realize a typology of the existing literature. We show that others theories explain the choice of non-financial measures too. For the knowledge-based view, we propose a synthesis of the existing literature in which the link between non-financial and theoretical explanations exists. Finally, we explain why the Balanced Scorecard can be associated to the disciplinary view and the Intellectual Capital to th…
