Bayesian Confirmation Measures can be used in ranking inductive rules obtained as an output when using Association Rules in database mining. Many measures of this kind have been defined and the choice of the right one can be considered as a further challenge to be faced. In this paper we try to...

We propose a class of preconditioners, which are also tailored for symmetric linear systems from linear algebra and nonconvex optimization. Our preconditioners are specifically suited for large linear systems and may be obtained as by-product of Krylov subspace solvers. Each preconditioner in...

In this paper we consider the parameter dependent class of preconditioners M(a,d,D) defined in the companion paper The latter was constructed by using information from a Krylov subspace method, adopted to solve the large symmetric linear system Ax = b. We first estimate the condition number of...

Exports represent an entry mode into international markets that is less risky than more direct strategies, therefore it particularly fits SMEs (small-medium enterprises) that generally have a few resources to invest. In the case of emerging markets because of the high psychic distance, SMEs tend...

In this paper, we focus on the internationalization strategies implemented by Middle Size Multinational Enterprises (MMNE) in Chinese markets. We assume that these strategies differs from those of the large multinational companies. Differences explained by the size of the company (medium)...

The optimal control problem of determining advertising efforts for a seasonal good in a heterogeneous market is considered. We characterize optimal advertising exposures under different conditions: the general situation in which several wide-spectrum media are available, under the assumption of...

Despite the effects of the crisis, several studies show that there has been an increase in cultural production in all the most important western countries over the last twenty years. Nevertheless, the dimensions of the flows of demand are changing: the lowering of the threshold of perceived...

In the general framework of globalization and internationalization, the paper focuses on the advertising strategies adopted by top companies in the luxury sector. The article reports on the preliminary data of a study to determine the importance of local culture in advertising content by...

The objective of this paper is to provide an analytical framework to study the whole process of diffusion of innovations, new products or ideas: we take into account knowledge transfer in a complex society, decisional process for adoption and key features in the spread of new technologies. For...
