  1. 1. Working conditions, compensatory strategies, and recovery

    Författare :Klas Gustafsson; Gunnar Aronsson; Bo Melin; Terry Hartig; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; recovery; compensatory strategies; working conditions; self-ratings; vacation; validation; sickness presenteeism; sickness absence; work organization; health; allostatic load; Psychology; Psykologi; psykologi; Psychology;

    Sammanfattning : The general aim of this thesis was to study and identify working conditions related to different types of compensatory strategies and to examine the relations between such strategies and recovery. Compensatory strategies refer to how people act in order to handle a great amount of work. LÄS MER

  3. 2. Barn till föräldrar med psykisk ohälsa : Barndom och uppväxtvillkor

    Författare :Annemi Skerfving; Alain Topor; Elisabet Näsman; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Children; childhood conditions; children as agents; parental mental illness mental disorders; mental health knowledge; exposed life situations; compentence; Barn; barndom; uppväxtvillkor; barns som aktörer; föräldrar med psykisk ohälsa sjukdom störning; kunskap om psykisk ohälsa sjukdom; utsatta livssituationer; Social Work; socialt arbete;

    Sammanfattning :  The aim of this doctoral thesis is to – from a child perspective and with children as informants – describe and analyze childhood conditions for children whose parents suffer from severe mental illness. The method used is qualitative – 28 children, 10 boys and 18 girls, 7–18 years old, were interviewed about their parents’ mental disorder; the family situation and their own personal life – in school and during free time.

  4. 3. Effects of visual load on auditory processing

    Författare :Malina Szychowska; Stefan Wiens; Mats E. Nilsson; Maria Larsson; Inga Griskova-Bulanova; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; EEG; event-related potential; mismatch negativity; auditory steady-state response; envelope following response; perceptual load; visual load; task difficulty; crossmodal attention; early-filter theory; adaptive filtering model; Psychology; psykologi;

    Sammanfattning : In daily life, people need to be able to focus on a task while ignoring any task-irrelevant background noise. For example, people who work in an open-space office may have to work on a report while ignoring the background talk among co-workers. LÄS MER

  5. 4. Efficient hull design for ice conditions in inland waterways

    Författare :Meng Zhang; Karl Garme; Magnus Burman; Pentti Kujala; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inland waterway ship; ice conditions; ice properties; ice-hull interaction; ice resistance; impact load; numerical method; operation time window; lightweight design; composites and sandwich structure; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : With increasing interest in utilizing the inland waterways (IWW) in European countries, the design of IWW vessels gains attention both from a transport efficiency and an emission control point of view. Usually, IWW ships are designed without ice operation concerns and are structurally weaker than ships designed according to ice-class notifications from the classification societies. LÄS MER

  7. 5. Dynamic Power System Load -Estimation of Parameters from Operational Data

    Författare :Ines Romero; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; large disturbances; Load modeling; normal operation; voltage stability; dynamic load models; modeling and identification; normalization in reactive load models; Elektronik och elektroteknik; Electronics and Electrical technology; Automatiska system; robotteknik; reglerteknik; Electrical engineering; Elektroteknik;

    Sammanfattning : The significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. LÄS MER
