  3. 2. Nonlinear Optical Materials Structural Studies of Alkali Titanium Phosphates

    Författare :Stefan Norberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonlinear optical materials; alkali titanium phosphates; phase transition; alkaline cation shifts; rare-earth langbeinites; doped KTP isostructures;

    Sammanfattning : Crystals are beautiful, not only as pieces of jewellery, but also for their intrinsic properties, which are of significant scientific and technological importance. Ferroelectric materials are extremely versatile, since they may be combined with piezoelectric or electrooptic devices for use as filters, oscillators, memories, light detectors, and displays.

  4. 3. Fearful attention : Investigating event-related potentials in spider phobia

    Författare :Joakim Norberg; Stefan Wiens; Jonas Persson; Harald Schupp; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; attention; phobia; event-related potential; Psychology; psykologi;

    Sammanfattning : Previous studies showed that emotional pictures capture attention. Further, this effect was decreased by manipulating spatial attention. In contrast, studies produced mixed findings for effects of perceptual load on attention to emotional pictures. Emotional pictures can be phobic or nonphobic. LÄS MER

  5. 4. Piecing together a fragmented world : Structures to promote the understanding of people with advanced dementia

    Författare :Catharina Melander; Malin Olsson; Stefan Sävenstedt; Britt-Marie Wälivaara; Astrid Norberg; Luleå tekniska universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dementia; nursing home; electrodermal activity; capability approach; clinical reasoning; assessment; behaviour; Nursing; Omvårdnad;

    Sammanfattning : Understanding people with dementia whose verbal ability has been impaired is a complex and challenging task, even for professional nursing staff. The aim of this PhD thesis was to explore structures that may promote the understanding of people with advanced dementia living in nursing homes. LÄS MER

  7. 5. Idrottslärare i blivande : meningsskapande, kontinuitet och förändring i övergångar mellan utbildning och yrkespraktik

    Författare :Runa Westerlund; Staffan Karp; Katarina Norberg; Stefan Lund; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; physical education teacher education; novice physical education teachers; meaningmaking; transition; idrottslärarutbildning; nyutexaminerade idrottslärare; meningsskapande; övergångar; education; pedagogik;

    Sammanfattning : Research and quality reports show a relatively unified picture of the school subject physical education (PE) as an educational context in which pupils are at risk of being marginalized or excluded. PE teacher education (TE) has a mission to equip all PE preservice teachers with knowledge and abilities that enable them to teach all pupils based on their individual needs and conditions. LÄS MER
