Walking as a transport mode : Examining the role of preconditions, planning aspects and personal traits for the urban pedestrian

The overall aim of this thesis is to examine how walking as a transport mode is constructed in the planning realm, affected by the built environment and perceived by the individual. This aim is related to the following research questions: (1) How are pedestrians and walking understood, constructed and perceived in the planning context? (2) How does individual traits and the built environment affec

A framework for understanding purchasing in building construction

Purchasing on the part of a building construction company involves actors inside and outside the organization. These actors are driven by different motives that influence purchasing decisions in different situations. An explicit framework that assists in understanding the different purchasing situations would be of benefit to companies and researchers.

Formation of Iduronic Acid during Chondroitin/Dermatan Sulfate Biosynthesis

All animals and some bacteria can synthesize linear polysaccharides with a backbone of repeating disaccharideunits, called glycosaminoglycans (GAGs). The GAGs are either attached to a protein core, as in proteoglycans (PGs), or exist as free polymer chains, as in hyaluronan. One of the most common types of GAGs is chondroitin/dermatan sulfate (CS/DS), where the repeating disaccharide backbone consAll animals and some bacteria can synthesize linear polysaccharides with a backbone of repeating disaccharideunits, called glycosaminoglycans (GAGs).

Editors’ Introduction : Conceptual Spaces at Work

This introductory chapter provides a non-technical presentation of conceptual spaces as a representational framework for modeling different kinds of similarity relations in various cognitive domains. Moreover, we briefly summarize each chapter in this volume.

Applications of Conceptual Spaces : the Case for Geometric Knowledge Representation

This volume provides an overview of applications of conceptual spaces theory, beginning with an introduction to the modeling tool that unifies the chapters. The first section explores issues of linguistic semantics, including speakers negotiation of meaning. Further sections address computational and ontological aspects of constructing conceptual spaces, while the final section looks at philosophi

Lakatos's challenge? : Auxiliary hypotheses and non-monotonous inference

Gerhard Schurz [2001, Journal for General Philosophy of Science, 32, 65-107] has proposed to reconstruct auxiliary hypothesis addition, e.g., postulation of Neptune to immunize Newtonian mechanics, with concepts from non-monotonous inference to avoid the retention of false predictions that are among the consequence-set of the deductive model. However, the non-monotonous reconstruction retains the

Monotonicity and reasoning with exceptions

A proposal by Ferguson [2003, Argumentation 17, 335-346] for a fully monotonic argument form allowing for the expression of defeasible generalizations is critically examined and rejected as a general solution. It is argued that (i) his proposal reaches less than the default-logician's solution allows, e.g., the monotonously derived conclusion is one-sided and itself not defeasible. (ii) when appli

Electric interactions: A study of cellulose

Detta arbete har haft som målsättning att fördjupa vår kunskap om cellulosa och hur denna polymer reagerar i olika miljöer. Cellulosa är det vanligaste organiska materialet på jorden vilket gör att det är relativt lätttillgängligt, billigt, och miljövänligt. Genom att öka vår förståelse av de egenskaper som cellulosa besitter kan det bli möjligt att utveckla nya användningsområden, men också kvaliThis work is primary about development and application of electrostatic theory within the atomistic domain. The resulting procedures were implemented to eventually describe systems involving the cellulose molecule. A concluding remark about electrostatic interactions is the importance of moment cancellation. By inducing image moments which cancels the totality of the collective system moments, and

Development of Novel Diffusion NMR Methods : Preclinical Applications in Colloidal Model Systems

Kärnmagnetisk resonans, NMR, är en teknik som har många användningsområden, inte minst används NMR som en bildgivande teknik för diagnostisering av skador och sjuk- domar, vilket görs med så kallade MR-kameror. Med hjälp av diffusions-NMR kan man mäta vattenmolekylers rörelse, d.v.s. vattnets diffusion. Diffusions-NMR gör det möjligt att mäta hur långt vattenmolekylerna rör sig i olika riktningar.NMR is a powerful non-invasive technique utilizing radiofrequency and gradient pulses to manipulate the spinsof atomic nuclei. In particular, diffusion NMR uses strong magnetic field gradients to label the positions of spins allowing for the measurement of translational motion of molecules in liquids. The average displacement of water molecules can give information on the pore microstructure in va

Ravens, New Caledonian crows and jackdaws parallel great apes in motor self-regulation despite smaller brains

Overriding motor impulses instigated by salient perceptual stimuli represent a fundamental inhibitory skill. Such motor self-regulation facilitates more rational behaviour, as it brings economy into the bodily interaction with the physical and social world. It also underlies certain complex cognitive processes including decision making. Recently, MacLean et al. (MacLean et al. 2014 Proc. Natl Acad
