Die vorliegende Arbeit liefert eine Strukturanalyse des deutschen Markts für Publikums- undFachzeitschriften. Dabei wurde sowohl der klassische Printbereich als auch der jüngere Online-Bereichdes Markts untersucht. Beide Marktsegmente weisen oligopolistische Tendenzen sowie starkenWettbewerb...

As using the Internet with mobile end devices like PDA or Smartphones gets more and more common,enterprises verify whether they can use this technology to gain competitive advantages. This workevaluates existing mobile applications for businesses, their technical construction and...

Due to decreasing hardware prices and growing standardization, RFID-systems (Radio FrequencyIdentification) are increasingly being used in global supply chains. In the beginning a simple identificationnumber was stored on the RFID tag, but meanwhile, there is a variety of applications storing...

In the wake of Web 2.0 applications, nearly every branch is influenced by this new understanding ofthe Web. The Banking industry is facing a phenomenon called Peer to Peer Banking, where customerstend to know exactly who gets their invested money. They want to know the people behind thecredit...

The majority of RFID implementations can be traced back either to mandates issued by companies or institutions withsignificant market power like Wal-Mart or the U.S. Department of Defense, or to the replacement of existing Auto-IDtechnologies like barcodes. Only sporadically is RFID being used...

Particle Swarm Optimization (PSO) has proven to be a good metaheuristic for continuous optimizationproblems. In this paper we present a solution for applying the PSO to a combinatorial optimizationproblem of a real data university course timetabling problem. We first describe the...

Scientific content or knowledge of scientists is useful only in case of distributing or communicating it from author to recipient. This is the task of the scientific communication system. As the first upcoming scientific journals superseding the individual letters between scientists in the...

The implementation of RFID leads to improved visibility in supply chains. However, as a consequenceof the increased data collection and enhanced data granularity, supply chain participants have to dealwith new data management challenges. In this paper, we highlight the primary characteristics of...

Particle Swarm Optimization is a population based search strategy based on the idea of the simulation of bird flocks. In this paper we will introduce an application of the PSO to a management problem. The simulated stochastic 2-product-warehouse with the parameters order amount and safety stock...

The number of scientific journals and thereby the number of published articles grew with an enormousrate in the last century (e.g. Price 1986; Henderson 2002). In the second half of the 20th century thesystem seemed to abut against its boundaries, because in relation to research budgets, library...
