The present study is concerned with the impact of psychological factors, particularly character traits and attitudes, on the traffic accident patterns of young drivers. 101 drivers completed a questionnaire consisting of 206 questions and statements. Factor analysis was used to identify and eliminate non-significant test items, leaving 70 statements defining 14 distinct traits. Age and sex were sh

En del personer går upp i vikt, andra inte. En viktig förklaring är överkonsumtion, men det finns också andra: låg ämnesomsättningshastighet, hög insulinkänslighet, låg energikostnad vid rörelse och låg fettförbränning. Alla dessa fenomen styrs av våra hunger- och mättnadssignaler. I boken beskrivs de senaste upptäckterna om hunger- och mättnadssignaler samt belöningssystem. En kunskap som ger os

This chapter describes various kinds of artificial light sources of interest to the photobiologist (natural light is described in separate chapters), starting with incandescent lamps and their properties, and continuing with gas discharge lamps, flashlamps, light-emitting diodes, and lasers. After a section on light filters, the chapter concludes with a treatment of monochromators, in which the mo

Popular Abstract in Swedish I en alltmer konkurrenskraftig omvärld är det av störst vikt att i ett högkostnadsland som Sverige att innovera och utveckla produkter så effektivt som möjligt. För att uppnå dessa mål finns det klara indikationer på att våra nuvarande produktutvecklings- och konstruktionstillvägagångssätt saknar väsentliga egenskaper för att uppnå önskvärd effektivitet. Den frekvent mIn an industrial context when the product development cycles are shortened and constraints on technical innovations are high, it is very important to provide a very efficient and effective engineering design activity. In the current engineering design literature, most methodologies are by and large based on the so-called systematic engineering design approach. This approach is characterized by an

We investigate the application of non-convex penalized least squares for parameter estimation in the Volterra model. Sparsity is promoted by introducing a weighted !q penalty on the parameters and efficient batch and time recursive algorithms are devised based on the cyclic coordinate descent approach. Numerical examples illustrate the improved performance of the proposed algorithms as compared th

A description of the cultural landscape in the Krageholm area, southern Sweden, during the Bronze Age.

The impact of European Union law on the regional and local levels in the Member States has been underestimated for a long time now. Today, however, it is clear that the impact of European Union law on these levels is important, not least as a consequence of the deregulation that has been carried out in most Member States in recent years. As local markets open up for competition, the scope of EU la

Product alternatives suggested by a generative design system often need to be evaluated on qualitative criteria. This evaluation necessitates that several feasible solutions which fulfill all technical constraints can be proposed to the user of the system. Also, as concept development is an iterative process, it is important that these solutions are generated quickly; i.e., the system must have a

The purpose of this paper is to compare pension schemes with respect to their intergenerational redistributive effects caused by economic and demographic changes. It is shown how these effects depend on the specific design of the pension scheme, with special attention devoted to the indexation problem. There is a potential trade-off between financial stability of the pension system and a “desired”

Popular Abstract in Swedish I litteraturen kring marknadsföring av tjänster har det i flera sammanhang diskuterats hur tjänster baserade på kombinationer av kundmedverkan och teknologi kan erbjudas till kunden. Exempel som behandlats är bankers uttagsautomater, självbetjäning på bensinstationer och automatiska banktjänster över telefon. Innan man kan presentera sådana rekommendationer behövs det gThis doctoral thesis deals with consumers’ attitudes towards serving them-selves with machines rather than being served by personnel. Its aim is to contribute to the theory of perceived service quality by providing a better understanding of customers’ attitudes and preferences when using technology-based self-service. In addition to aspects of service dealt with by traditional service-quality rese

Friction may be a major obstacle for stability and control performance. Based on a nominal control law, which stabilizes a nonlinear dynamical system to an equilibrium or to a desired limit cycle motion and which is derived without taking the friction disturbance into account, a method for compensating the impact of the friction is presented and stability analysis for the closed loop system is pre
