Correctness, transparency and effectiveness are the principal attributes of knowledge derived from databases. In current data mining research there is a focus on efficiency improvement of algorithms for knowledge discovery. However important limitations of data mining can only be dissolved by...

We analyze the initial intellectual property (IP) right of 4,703 start-up entrants in the US, distinguishing between trademark and patent applications. The results show that start-ups are more likely to file for a trademark instead of a patent when entering into more competitive market...

While it is generally acknowledged that entrepreneurship as well as export activity may both be important strategies for achieving national economic growth, it has remained unclear how export activity among new ventures is related to economic growth. This paper investigates whether the presence...

This case study examines the capital budgeting practices of four companies operating in different industry. The findings indicate that most companies follow decentralised project decision-making. Despite the use of DCF techniques, there is a tendency to combine with the newly crafted value...

A principal-agent model is formulated to capture the efficiency of cooperatives with a member CEO and cooperatives with an employed outsider as CEO. Results of the model show that the incentive strength regarding the member CEO is stronger compared to that of the outside CEO in order to shift...

The dependence between asset returns varies. Its strength can become stronger or weaker. Also, its structure can change, for example, when asymmetries related to bull and bear markets become more or less pronounced. To analyze these different types of variations, we develop a model that...

The case of the Danish “cartoon war” was a premonition of things to come: accelerated social construction of inequalities and their accelerated symbolic communication, translation and negotiation. New uses of values in organizing and managing inequalities emerge. Values lead active social...

Many content-based recommendation approaches are based on a dissimilarity measure based on the product attributes. In this paper, we evaluate four dissimilarity measures for product recommendation using an online survey. In this survey, we asked users to specify which products they considered to...

This paper develops a novel statistic for firm efficiency called efficiency depth that allows for statistical inference in case of errors-in-variables. We derive statistical tests that require minimal statistical assumptions; neither the sample distribution nor the noise level is required. An...

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....
