  1. 1. Imaging Anxiety : Neurochemistry in Anxiety Disorders Assessed by Positron Emission Tomography

    Författare :Andreas Frick; Mats Fredrikson; Tomas Furmark; David J Nutt; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Fear; Brain; Serotonin; Neurokinin; Substance P; Psychology; Psykologi;

    Sammanfattning : Anxiety disorders, including social anxiety disorder (SAD) and posttraumatic stress disorder (PTSD) are common and disabling conditions. Largely based on animal and pharmacological studies, both the serotonergic and substance P/neurokinin-1 (SP/NK1) systems have been implicated in their underlying pathology. LÄS MER

  5. 4. Diagnosing Sharing Anxiety

    Författare :Sigma Dolins; Chalmers University of Technology; []
    Nyckelord :ridehailing; sharing anxiety; shared autonomous vehicles; ridepooling; on-demand transport; qualitative methods; shared autonomous public transport; autonomous vehicles; public transport;

    Sammanfattning : Numerous studies indicate that the potential of autonomous vehicles (AVs) to reduce greenhouse gas emissions, reduce traffic congestion, and increase mobility access can only be fully realized through fleets of vehicles being used for shared rides, also known as dynamic ridepooling. This has the potential for transforming the public transport industry, as well as how transportation functions in urban and rural contexts. LÄS MER
