  1. 26. Different is cool! Self-efficacy and participation of students with and without disabilities in school-based Physical Education

    Författare :Karin Bertills; Mats Granlund; Lilly Augustine; Marte Bentzen; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Self-efficacy; participation; disability; physical education; secondary school;

    Sammanfattning : Background: Self-efficacy predicts school achievement. Participation is important for life outcomes. Functioning affects to what degree you can participate in everyday life situations. Participation-related constructs such as self-efficacy and functioning work both as a means of participation and as an end outcome. LÄS MER

    Sammanfattning : The chemical bond – a corner stone in science and a prerequisite for life – is the focus of this thesis. Fundamental and applied aspects of chemical bonding are covered including the development of new computational methods for the characterization and rationalization of chemical interactions. LÄS MER

  5. 29. Human motor control, autonomic and decision processes under physical and psychological stress. Instinctive, reflexive and adaptive aspects

    Författare :Johan Bertilsson; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Neuroendocrine stress response; Pepper spray; Police officer involved shootings; Memory distortions; Motor control;

    Sammanfattning : The stress response is governed by automatic neurological and hormonal processes that occur before we become consciously aware of a dangerous situation. If stress ensues for 15-30 seconds, the hormonal processes may have progressed so far that recovery takes an hour or longer instead of minutes. LÄS MER

  7. 30. Advanced all-fiber optofluidic devices
