  1. 21. Risk and Rates of Time Preferences of Farm Households in Ethiopia: Implications on land investment decisions

    Författare :Mahmud Yesuf; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Summary Paper 1: Risk Preferences of Farm Households in Ethiopia: Implications to Land Investment Decisions This paper measures farmers' attitude towards risk using an experimental approach for a sample of 262 farm households in Ethiopian highlands. We find more than 50 percent of the households in severe to extreme risk aversion category, unlike similar studies in Asia, where the vast majorities are found under moderate to intermediate risk aversion category.

  4. 23. Exploring the Transition to a Low-Carbon Electricity System — Using Agent-Based Modeling

    Författare :Jinxi Yang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; investment decisions; agent-based modeling; energy system modeling; open-source model; electricity market; low-carbon transition;

    Sammanfattning : The ability to produce electricity has profoundly shaped human lives. Over time, the sources used for electricity generation have undergone several transitions. Currently, we are navigating a pivotal shift in the electricity system – decarbonization – a journey fraught with a myriad of challenges. LÄS MER

  5. 24. Non-caloric regulation of food intake

    Författare :Anica Klockars; Dan Larhammar; Michael Williams; Robert Fredriksson; Karolina Skibicka; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroscience; Neurovetenskap;

    Sammanfattning : Food intake is shaped by environmental, endocrine, metabolic, and reward-related signals. A change in appetite is an outcome of integration of the relevant external and internal stimuli. While the main purpose of eating is to reverse a negative energy balance, mechanisms protecting homeostasis change appetite for other reasons. LÄS MER

  7. 25. Specifying the Heterogeneity in Children with ADHD : Symptom Domains, Neuropsychological Processes, and Comorbidity

    Författare :Cecilia Wåhlstedt; Gunilla Bohlin; Björn Lyxell; Uppsala universitet; []
    Nyckelord :ADHD; Heterogeneity; Hyperactivity Impulsivity; Inattention; Neuropsychological Pathways; Comorbidity; Psychology; Psykologi;

    Sammanfattning : Heterogeneity in children with Attention Deficit Hyperactivity Disorder (ADHD) symptoms is a well-known phenomenon. Empirically, this heterogeneity is evident in at least three different respects: expression of the two ADHD symptom domains (hyperactivity/impulsivity and inattention), neuropsychological impairments, and comorbid behavior problems.
