  1. 1. Exploring and modeling response process data from PISA : inferences related to motivation and problem-solving

    Author : Erik Lundgren; Hanna Eklöf; Inga Laukaityte; Per-Erik Lyrén; Samuel Greiff; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; response processes; large-scale assessments; motivation; problem-solving; computational modeling; Bayesian modeling; didactics of educational measurement; beteendevetenskapliga mätningar;

    Abstract : This thesis explores and models response process data from large-scale assessments, focusing on test-taking motivation, problem-solving strategies, and questionnaire response validity. It consists of four studies, all using data from PISA (Programme for International Student Assessment) data. READ MORE

  2. 2. Obsessive-compulsive disorder, serotonin and oxytocin : treatment response and side effects

    Author : Mats B. Humble; Ingemar Engström; Lars von Knorring; Lars Kjellin; Lil Träskman-Bendz; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adverse effects; Obsessive-compulsive disorder; Orgasm; Oxytocin; Randomised controlled trial; Rating scale; Response prediction; Serotonin; Serotonin uptake inhibitors; Sexual function; Psychiatry; Psykiatri;

    Abstract : Obsessive-compulsive disorder (OCD), with a prevalence of 1-2 %, frequently leads a chronic course. Persons with OCD are often reluctant to seek help and, if they do, their OCD is often missed. This is unfortunate, since active treatment may substantially improve social function and quality of life. READ MORE

  3. 3. Structural Earthquake Response Analysis

    Author : Hamid Movaffaghi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element method; Earthquake excitation; global and local optimization; viscoelastic passive dampers; stochastic simulation; structural earthquake response analysis;

    Abstract : AbstractEarthquakes are one of the most dangerous natural phenomena causing damage to buildings and other structures as well as injury and death of people. These destructive processes can never be prevented to happen, but their impact on the structures can be minimized. READ MORE

  4. 4. Continuum modeling of paperboard for the mechanical response of converting processes

    Author : Kristofer Robertsson; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Continuum modeling; Converting processes; FEM simulations; Finite strain theory; Damage modeling; Rate-dependent; Creasing and folding; Out-of-plane experiments;

    Abstract : Paperboard is a thin and lightweight material made of cellulose fibers and it is an important component in packaging material where it provides stiffness and rigidity. The scope of this work is the development of continuum models, and its numerical treatments, for simulating the processes of converting paperboard into packages. READ MORE

  5. 5. Ecosystem processes and biodiversity : theoretical studies and experiments with an aquatic model ecosystem

    Author : Jon Norberg; Michael L Pace; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Systems Ecology; systemekologi;

    Abstract : Today, human enterprise has implications for all of nature, from the well being of the smallest organism, to the alteration of global biogeochemical cycles. To understand how major ecosystem processes are affected by environmental changes and decreasing biodiversity is crucial as many of natures services depend of such processes. READ MORE
