Public procurement for innovation is a matter of using public demand to trigger innovation. Empirical studies have demonstrated that demand-based policy instruments can be considered to be a powerful tool in stimulating innovative processes among existing firms. However, the existing literature has not focused on the role this policy instrument can play in the promotion of (knowledge-intensive) en

Although Moral Foundations Theory claims that the foundations of morality are universal, there are still few studies addressing it through non-English measures. In the current research, 540 persons filled out a Swedish translation of the Moral Foundations Questionnaire, and 332 of them filled out political attitude measures. Confirmatory factor analyses suggested that the fit of the five-factor mo

Direkt Profil is an automatic analyzer oftexts written in French as a second lan-guage. Its objective is to produce an eval-uation of the developmental stage of stu-dents under the form of a grammaticallearner profile. Direkt Profil carries outa sentence analysis based on developmen-tal sequences, i.e. local morphosyntacticphenomena linked to a development in theacquisition of French.The paper pre

By using an integrated dynamic model we are able to reconstruct the supply and gold price of the past (1920-2010) and this is used to predict the future supply of gold to the market and to make a forecast of the goldprice 2010-2100. The model was validated against field data for the period 1920-2010 and it performs well. The model GOLD is implemented in the STELLA® software and the model described

Full-scale ethanol production from spruce has been evaluated, mainly from an energy perspective, using an Aspen Plus-model including all major process steps. The model input was based on data recently obtained on lab scale or in a process development unit. A number of different process configurations are presented in order to demonstrate how heat integration within the ethanol process significantl

Diskussion kring begreppen centralplats och stad. Jämförelse mellan det vikingatida Uppåkra och det tidigmedeltida Lund.

Hakkarainen and Sintonen (2002) praise the descriptive adequacy of Hintikka's Interrogative Model of Inquiry (imi) to describe children's practices in an inquiry-based learning context. They further propose to use the imi as a starting point for developing new pedagogical methods and designing new didactic tools. We assess this proposal in the light of the formal results that in the imi characteri

Urinary tract infection is the most common infection in man. P fimbriae are virulence factors of uro-pathogenic Escherichia coli. They are expressed by 70-90 % of acute pyelonephritis isolates and up to 100% of the most virulent isolates that cause bacteremia. This thesis concerns the interaction between P fimbriae and the urinary tract mucosa, and the host receptors involved in fimbrial recognit

Abstract in UndeterminedThe use of a polar diagram method for describing and evaluating the machinability ofInconel 718 was explored. Five key parameters of the work material, representing themechanical and physical properties, which have the strongest influence on its machinability,were employed in the diagrams. These five parameters were integrated into asingle polar diagram, used to describe th

The self-diffusion coefficients of water in casein solutions and gels were measured using a pulsed-gradient spin-echo nuclear magnetic resonance technique (PGSE NMR). The dependence of the self-diffusion coefficient of water on the concentration and structure-of casein is reported. The results were analyzed using a cell model. It was found that the water self-diffusion coefficient is insensitive t

Proteins can adjust their structure and function in response to shifting environments. Functional diversity is created not only by the sequence but by changes in tertiary structure. Here we present evidence that lipid cofactors may enable otherwise unstable protein folding variants to maintain their conformation and to form novel, biologically active complexes. We have identified unsaturated C18 f

Rats and mice with a lower capacity to produce reactive oxygen species (ROS) because of allelic polymorphisms in the Ncf1 gene (which encodes neutrophil cytosolic factor 1) are more susceptible to develop severe arthritis. These data suggest that ROS are involved in regulating the immune response. We now show that the lower capacity to produce ROS is associated with an increased number of reduced

Epithelial cells are characterized by their polarized organization based on an apical membrane that is separated from the basolateral membrane domain by tight junctions. Maintenance of this morphology is guaranteed by highly specific sorting machinery that separates lipids and proteins into different carrier populations for the apical or basolateral cell surface. Lipid-raft-independent apical carr

Our aim in this study was to explore women's responses to reported ad-hoc demands for unauthorized user fees during pregnancy and childbirth in Luanda, Angola. Ten focus group discussions were conducted and data were analysed using grounded theory. Women were found to apply six strategies as they "endeavored to cope with demands for unauthorized user fees" (core category): (i) blowing the whistle,
