1. 1. Lifelong learning : The social impact of digital villages as community resource centres on disadvantaged women

   Författare :David Hallberg; Anders G. Nilsson; Christina Keller; Lars Svensson; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; community resource centre; digital village; disadvantaged women; lifelong learning; social change; social impact; social informatics; stressor; telecentre; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : The overall aim of this research was to enhance the understanding of what affects the social impact of ICT in lifelong learning on disadvantaged women.In contributing to the field of social informatics, this research employs behavioural theories as strategy and analytic possibilities.

3. 2. I feel terrible! Can you measure that? : Exploring psychophysiological stress responses and their interactions with performance, subjective reports and health status

   Författare :Anna Sjörs; Torbjörn Falkmer; Björn Gerdle; Britt Larsson; Ulf Lundberg; Linköpings universitet; []
   Nyckelord :psychophysiology; motion sickness; chronic pain; stressor; performance; autonomic responses; HPA axis; MEDICINE; MEDICIN;

   Sammanfattning : Despite recent research advances, there are still several common medical conditions whose underlying mechanisms are poorly understood. In conditions with few or diffuse physical findings, it can be difficult to diagnose and determine the state of the condition and its effects on working ability or performance, and the health care practitioners have to rely on the patient’s self-reports.

4. 3. The sleep of the child – the parent's stressor? : A study within the ABIS project

   Författare :Peder Palmstierna; Ulf Samuelsson; Anneli Sepa; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Poor sleep and chronic stress are important factors detrimental to physical and mental health. This is no less true for children than for adults. Therefore, investigating sleep and stress patterns in early life is important. LÄS MER

5. 4. Impacts of urbanisation on birds : Disentangling the effects of multiple pollutants on avian behaviour and physiology

   Författare :Ann-Kathrin Ziegler; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial light at night; ALAN; antioxidants; great tit; light pollution; LPS; multi-stressor; noise pollution; tropospheric ozone; urbanisation; zebra finch;

   Sammanfattning : Anthropogenic pollution is a pervasive feature of urbanisation, reaching into ecosystems worldwide and posing novel challenges to wildlife. Not surprisingly, differences in behaviour, and physiology, have been found between urban and rural populations. LÄS MER

7. 5. Psychotropic Pharmaceuticals in Aquatic Systems: An Ecological Perspective

   Författare :Melanie Hedgespeth; Enhet akvatisk ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ecotoxicology; aquatic; trophic level; pharmaceutical; SSRI; beta-blocker; sertraline; fluoxetine; propranolol; fish; daphnia; snail; predator; prey; behavior; life history; multiple stressor;

   Sammanfattning : Psychotropic pharmaceuticals have been shown to exert a variety of sublethal effects on non-target organisms, even at low concentrations found in the environment (ng/L to µg/L); hence, the aim of my research has been to determine the individual-level effects of psychotropic pharmaceuticals (the selective serotonin reuptake inhibitors sertraline and fluoxetine, and the β-blocker propranolol) on behavioral and life history traits in freshwater organisms. Further, this research was directed towards assessing the potential large-scale impacts of these effects on population growth and predator-prey interactions (with community-level implications) via the application of traditional, ecological concepts and models.
