  2. 1. Speed Choice : The Driver, the Road and Speed Limits

    Author : Mats Haglund; Nils Petter Gregersen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Driving behaviour; Speed choice; Risk estimates; Enforcement; Attitudes; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Speed choice is one of the more characteristic features of driver behaviour. The speed a driver chooses to travel at determines the degree of difficulty he or she operates under. Higher speeds lead to more accidents, higher accident risk and more severe consequences of an accident. READ MORE

  4. 2. Loyal Speed Adaptation Speed limitation by means of an active accelerator and its possible impacts in built-up areas

    Author : Sverker Almqvist; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active accelerator; LSA; speed; speed reduction; driver behaviour; traffic safety; ISA; Teknik; Technological sciences; Road transport technology; Vägtransportteknik;

    Abstract : Traditional measures for improved traffic safety need to be complemented by modern technologies in the struggle to reduce the consequences of traffic accidents all over the world. This thesis introduces the Loyal Speed Adaptation (LSA) function based on recent developments in the area of Intelligent Transport Sys-tems to support the vehicle drivers in not using inappropriate or excessive speeds, which have been found to be an important factor for causing serious and fatal accidents.

  5. 3. Predator psychology and mimicry evolution - a theoretical analysis

    Author : Alexandra Balogh; Olof Leimar; Michael Speed; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Müllerian mimicry; two-step evolution; gradual evolution; mutualism; predator psychology; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

    Abstract : The evolution of Müllerian mimicry depends on many factors, among which predator psychology is the most important one. Predator avoidance learning, generalization and discrimination are primary selective agents during the evolutionary process. READ MORE

  6. 4. High-resolution Studies of mRNA Expression in Brain : A Search for Genes Differently Expressed in Schizophrenia

    Author : Anja Castensson; Elena Jazin; Terence Speed; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; mRNA; gene expression; real-time RT-PCR; schizophrenia; 5-HT serotonin receptor 2C; brain; psychiatric genetics; Genetik; Clinical genetics; Klinisk genetik;

    Abstract : Gene expression differences between patients and controls can be used to find susceptibility genes and drug targets for a disease. High-resolution strategies are required because the differences between the investigated groups may be small and numerous factors may affect the mRNA quantity. READ MORE

  7. 5. Evolution of Mimicry and Aposematism Explained: Salient Traits and Predator Psychology

    Author : Baharan Kazemi; Olof Leimar; Gabriella Gamberale-Stille; Mike Speed; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; imperfect mimicry; mimicry evolution; predator learning; discrimination; generalization; salience; overshadowing; aposematism; warning signal evolution; generalization bias; peak shift; etologi; Ethology;

    Abstract : Aposematic species have evolved conspicuous warning signals, such as bright colors and striking patterns, to deter predators. Some edible and harmless species take advantage of this deterrent effect by mimicking their appearance. Mimicry is a great example of how natural selection produces remarkable adaptations. READ MORE
