This volume is a collection of some of the most important philosophical papers by Peter Gärdenfors. Spanning a period of more than 20 years of his research, they cover a wide ground of topics, from early works on decision theory, belief revision and nonmonotonic logic to more recent work on conceptual spaces, inductive reasoning, semantics and the evolutions of thinking. Many of the papers have on

This memo reports on factors that drive and inhibit the digitalization of security systems. The reported factors are as follows: Technology-push factors • Need to lower costs on the end-user side, i.e. replacing labour with technology • Perceived convenience and ease-of-use of digital systems • Digital products can be connected to the current enterprise network; enabling an expanding set of secur

Popular Abstract in Swedish Proteiner är livsnödvändiga och finns i alla celler. De flesta proteinerna katalysear kemiska reaktioner och kallas då enzymer. Enzymer och proteiner (äggviteämnen) är uppbyggda av aminosyror ihopkopplade till kedjor som kan vara olika långa. Det finns 20 stycken olika aminosyror. Man kan göra en liknelse med ett pärlhalsband tillverkat av 20 olika pärlor, varje pärla mFerrochelatase catalyses the terminal step in heme biosynthesis by inserting a ferrous ion into protoporphyrin IX. The reaction mechanism has in this thesis been studied by mainly crystallographic methods. The structure of ferrochelatase from Bacillus subtilis co-crystallized with N-methyl mesoporphyrin allowed for the first time a characterization of the active site of the enzyme. The structure

Financial theory, resource-based theory and deal flow generation are used to explain synd ication practices among venture capitalists in Belgium, France, The Netherlands, Sweden and the UK. Similar motives drive syndication in the five countries: the desire to share risk and increase portfolio diversification is more important than the desire to access additional intangible resources or deal flow.

Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. Since the positions of the rollers, and thereby also the load distribution, depend on the two connecting spans, it has been necessary to inclu

A systematic study of cell membrane morphologies whose structure is governed by cubic symmetries has been performed. It is suggested that they are described by periodic cubic surfaces for which space filling surface foliations given by truncated Fourier series defined by the space groups is used as structural representations. Using this a method is developed which enables a direct ultrastructural

This paper examines how social relations and norms contribute to the emergence of generalized trust in economic action. Our core proposition is that the more positive the local social exchange relationship, the greater an actor’s propensity to place trust in strangers. Our research design integrates behavioral measures elicited by incentivized experimental trust games with survey data using a rand

The Gas in scattering media absorption spectroscopy (GASMAS) technique provides new opportunities to nondestructively study gas in highly scattering natural and man-made porous materials. In this paper, we report applications of the GASMAS method on wood samples using diode-laser-based spectroscopy on molecular oxygen. And the integrated oxygen absorption for wood of different densities and the an
