In this paper, we propose that affective reactions are integral to capital budgeting, and that researchers must jointly consider affect and cognition to better understand capital-budgeting decision makers' behavior. Capital budgeting is very important to firms. Capital-budgeting activities are critical to a company's long-term performance. Interpersonal relationships can lead to emotional affective...
Current economical context and industrialization accelerate product development and put forward automation. Still, product development requires also human intervention in a number of activities which cannot be entirely achieved by machines. It is the case of product development for railway markets, where the design of railway systems is guided by the evolving needs of the customers. Therefore, there...
Emotions play a key role in any purchasing process even more when it is done through web portals. In this paper, we present a fuzzy-logic based system aimed to generate emotions for a virtual seller or avatar. The 3D avatar is integrated within the e-Zoco e-commerce portal and its behaviour depends on the product search results. Moreover, the mood of the avatar not only depend on the products that...
The Generalized Second Price Auction has been the main mechanism used by search companies to auction positions for advertisements on search pages. In this paper we study the social welfare of the Nash equilibria of this game in various models. In the full information setting, socially optimal Nash equilibria are known to exist (i.e., the Price of Stability is 1). This paper is the first to prove bounds...
Little is known about problems encountered in distributed Agile development environments. There have been some case studies reporting on them. However, these studies have been mainly limited to the scope and context of only one or a few companies. As a result, we do not possess an overall picture of what types of problems and challenges the companies may encounter in distributed Agile environments...
In order to satisfy dynamic authorization in service-oriented grid environment, a context and trust-based grid service authorization model (CTGSA) is proposed. First, model is defined formally. Benefiting from the mapping relation of user-role, role-service and service-resource assignment, model can provide authorization using service-oriented method, which reduces the management overhead greatly...
This paper explores the emergence and characteristics of what Vree has called inverse infrastructures - a category of user-driven, self-organizing infrastructures, primarily characterized by bottom-up development and decentralized control. They are `inverse' in respect to the large-scale centralized infrastructures dominant today. Drawing from ICT cases, it identifies, characterizes and examines the...
