Academic communities in social sciences are still dominated by neo-positivist paradigm, but communities of practice developing social constructivism have started to redress paradigmatic imbalances. According to the latter man-made organizational reality is processual and saturated with...

We propose a taxonomy of bibliometric indicators of scientific performance. The taxonomy relies on the property of consistency. The h-index is shown not to have this important property.

Due to the present-day memory sizes, a memory-resident database has become a practical option. Consequently, new methods designed to mining in such databases are desirable. In the case of disk-resident databases, breadth-first search methods are commonly used. We propose a new algorithm, based...

In this note we present an efficient exact algorithm to solve the joint pricing and inventory problem for which Bhattacharjee and Ramesh (2000) proposed two heuristics. Our algorithm appears to be superior also in terms of computation time. Furthermore, we point out several mistakes in the paper...

In this paper we consider the uncapacitated economic lot-size model, where demand is a deterministic function of price. In the model a single price need to be set for all periods. The objective is to find an optimal price and ordering decisions simultaneously. In 1973 Kunreuther and Schrage...

The state of the equity market, often referred to as a bull or a bear market, is of key importance for financial decisions and economic analyses. Its latent nature has led to several methods to identify past and current states of the market and forecast future states. These methods encompass...

Means-end relations are generally assumed to be hierarchical, and, by implication, asymmetrical. That is, if A is a means to achieve B, B is not at the same time also a means to achieve A. Literature casting doubt on this directedness of means-end relations is reviewed, and the hypothesis of...

We examine the relation between the quality of corporate governance and the value of excess cash for large European firms (FTSEurofirst 300 Index). We use Deminor ratings for Shareholder rights, Takeover defences, Disclosure and Board as proxies for the quality of corporate governance. We find...

Despite their strategic importance firm’s motivations to extend brands have received only modest attentions by marketing scholars. We use multiple events duration models to examine the timing of launching brand extensions. We provide a theoretical framework of brand extensions based on the...

In content- and knowledge-based recommender systems often a measure of (dis)similarity between products is used. Frequently, this measure is based on the attributes of the products. However, which attributes are important for the users of the system remains an important question to answer. In...
