This thesis explores the effects of institutional arrangements for innovation in clusters. Clusters have become one of the most popular concepts in innovation policy studies in recent years. They have been ascribed as places with structures that reduce transaction costs, and enable innovation processes due to the prevalence of different types of externalities. The focus of this dissertation is on

As the concept of gentrification celebrates an even forty years, some of the most basic questions about the process itself remain contentious. What is gentrification? What are its root causes? There is surely no lack of answers, though these are largely stamped by disciplined convention. The purpose of this chapter is to revisit these basic questions and formulate answers that facilitate “having g

The manual is intended for managers, teachers and practitioners working with adults in universities. It may also be of interest to staff trainers and professional development co-ordinators, policy makers and administrators with an interest in adult higher learning, staff of national agencies who have a role to play in increasing adult participation in universities, adult learners, or indeed anyone

Changes in Swedish food consumption patterns during recent decades are studied together with some possible future changes of importance for increasing resource efficiency. The increased consumption of meat and a more global food supply have contributed negatively. An increased interface with foreign food cultures through travelling and immigration are the main causes of these consumption changes.

Performance modeling is an important topic in capacity planning and overload control for web servers. We present an M/G/1/K*PS queueing model of a web server. The arrival process of HTTP requests is assumed to be Poissonian and the service discipline is processor sharing. The total number of requests that can be processed at one time is limited to K. We obtain closed form expressions for web serve

We present a study of a novel variant of the Self-Organizing Map (SOM) called the Associative Self-Organizing Map (A-SOM). The A-SOM is similar to the SOM and thus develops a representation of its input space, but in addition it also learns to associate its activity with the activity of one or several external SOMs. The A-SOM has relevance in e.g. the modelling of expectations in one modality due

A consortium of interested parties has conducted an experimental characterization of two Tau parallel kinematic machines which were built as a part of the EU-funded project, SMErobot1. Characteristics such as machine stiffness, work envelope, repeatability and accuracy were considered. This paper will present a brief history of the Tau parallel machine, the results of this testing and some comment

Organizations need to make sure that their level of safety is acceptable. Therefore it is important to know which factors contribute to the level of safety and how to monitor and improve these factors. One method used today to evaluate the level of safety in organizations is safety culture measurements. In different contexts, different models of safety culture are used. Safety culture is often con
