In this technical report , two new algorithms based upon frequent patterns are proposed. One algorithm is a classification method. The other one is an algorithm for target group selection. In both algorithms, first of all, the collection of frequent patterns in the training set is constructed....

We present a mathematical analysis of the long-run behavior of genetic algorithms that are used for modeling social phenomena. The analysis relies on commonly used mathematical techniques in evolutionary game theory. Assuming a positive but infinitely small mutation rate, we derive results that...

In this article, we demonstrate that a direct relation exists between the context of Japanese firms indicating relative distress and conditional return distribution properties. We map cross-sectional vectors with company characteristics on vectors with return feature vectors, using a fuzzy...

Female and male entrepreneurs differ in the way they finance their businesses. This can be attributed to the type of business and the type of management and experience (indirect effect). Female start-ups may also experience other barriers based upon discriminatory effects (direct effect)....

The modifiable areal unit problem (MAUP) refers to the sensitivity of statistical research results to the initial spatial nomenclature used. Despite a substantial literature in the related field of geography on the potential influence of the MAUP, the urban economic modeling tradition has not...

This paper deals with Case-based Reasoning (CBR) as a support technology for sales promotion (SP) decisions. CBR-systems try to mimic analogical reasoning, a form of human reasoning that is likely to occur in weakly-structured problem solving, such as the design of sales promotions. In an...

The purpose of this paper is to document the fundamental shift that is taking place in OECD countries. This shift is from the managed economy to the entrepreneurial economy. While politicians and policy makers have made a plea for guidance in the era of entrepreneurship, scholars have been slow...

Both in theory as in practice insight is limited about how firms in dynamic environments could organize to manage concurrently both the strategic processes of competence building and competence leveraging. To contribute to this issue, a conceptual framework is developed which considers the...

This paper attempts to develop concepts of project and contract organization to predict the selection of contract type on infrastructure projects. Conventional wisdom is that at low risk fixed price contracts are best, moving to remeasurement and then cost plus as risk increases. We started...

This paper explores whether websites that offer a global audience virtual access to watering holes in game parks afford African nations opportunities to diminish their international isolation as tourism destinations. The present analysis examines a sample of almost 450 tourism websites...
