Modular decomposition is a thoroughly investigated topic in many areas such as switching theory, reliability theory, game theory and graph theory. Most appli- cations can be formulated in the framework of Boolean functions. In this paper we give a uni_ed treatment of modular decomposition of...

Research on work group diversity has more or less neglected the possibility that reactions to diversity may be informed by individuals' beliefs about the value of diversity (vs. homogeneity) for their work group. We studied the role of such diversity beliefs as a moderator of the relationship...

Plural form franchising is modeled from an incomplete contracting perspective. Complete franchising is the unique, efficient governance structure only when the plural form externality is limited and the costs of investment are low for both franchisees. Governance structure choice is irrelevant...

This paper introduces individual tariffs at service and content bundle level in mobile communications. It gives a theoretical framework (economic, sociological) as well as a computational game solution method. The user can be an individual or a community. Individual tariffs are decided through...

A design approach is offered for individual tariffs for mass customized mobile service products, whereby operators can determine their contract acceptance rules to guarantee with a set probability their minimum profit and risk levels. It uses realistic improvements to earlier reported...

Replication is conducting a study in another case (or population) in order to assess whether a research finding from previous studies can be confirmed. The aim of replication is to assess the generalizability of a theoretical claim and the “research finding” that is (or is not) confirmed in...

Ideals (or ideal values) help people to navigate in social life. They indicate at a very fundamental level what people are concerned about, what they strive for, and what they want to be affiliated with. Transferring this to a leader-follower analysis, our first Study (N = 306) confirms that...

In today’s multicultural societies, ethnic targeting is increasingly important for marketing. Two main approaches to target ethnic minorities have emerged: messaging consumers when their ethnic identity is most salient, and featuring spokespeople who have the same heritage as the target. We...

Aside from the aggregated information provided by price and quantity indexes, there is growing interest in index decompositions that reveal the contribution of each index component to overall index change. In this paper, we derive a “natural” decomposition of the Fisher price index that is...

In this paper we will show that the closely K-convexlike vector-valued functions with K Rm a nonempty convex cone and related classes of vector-valued functions discussed in the literature arise naturally within the theory of biconjugate functions applied to the Lagrangian perturbation scheme in...
