1. 1. Dream affect : Conceptual and Methodological Issues in the Study of Emotions and Moods Experienced in Dreams

   Författare :Pilleriin Sikka; Antti Revonsuo; Katja Valli; Antonio Zadra; Högskolan i Skövde; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dreaming; affect; emotions; self-ratings; external ratings; REM sleep; well-being; peace of mind; frontal alpha asymmetry; Consciousness and Cognitive Neuroscience; Kognitiv neurovetenskap och filosofi;

   Sammanfattning : We experience affect—emotions and mood—not only when we are awake but alsoduring dreaming. Despite considerable research, existing theories and empiricalfindings disagree about the frequency, nature, and correlates of dream affect. In thisthesis, I discuss the conceptual and methodological issues that underlie thesediscrepancies. LÄS MER

3. 2. The rolling resistances of roller skis and their effects on human performance during treadmill roller skiing

   Författare :Mats Ainegren; Peter Carlsson; Marko Laaksonen; Per Tesch; Mittuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood lactate; cycle length; cycle rate; heart rate; oxygen uptake; performance; power; roller skis; rolling resistance; ratings of perceived exertion; work economy; Sports; Idrott;

   Sammanfattning : Modern ski-treadmills allow cross-country skiers, biathletes and ski-orienteers to test their physical performance in a laboratory environment using classical and freestyle techniques on roller skis. For elite athletes the differences in performance between test occasions are quite small, thus emphasising the importance of knowing the roller skis’ rolling resistance coefficient, µR, in order to allow correct comparisons between the results, as well as providing the opportunity to study work economy between different athletes, test occasions and core techniques.

4. 3. Roller skis' rolling resistance and grip characteristics : influences on physiological and performance measures in cross-country skiers

   Författare :Mats Ainegren; Peter Carlsson; Marko Laaksonen; Mittuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adjustable grip; blood lactate; centre of pressure; cycle length; cycle rate; economy; efficiency; friction coefficient; heart rate; normal force; OBLA; oxygen uptake; power; ratcheted wheel; ratings of perceived exertion; roller skis; rolling resistance; tangential force; time to exhaustion;

   Sammanfattning : The aim of this thesis was to investigate roller ski characteristics; classical and freestyle roller skis’ rolling resistance coefficients (μR) and classical style roller skis’ static friction coefficients (μS), and to study the influence of different μR and μS on cross-country skiers’ performance and both physiological and biomechanical indices. The aim was also to study differences in skiing economy and efficiency between recreational skiers, female and male junior and senior elite cross-country skiers. LÄS MER

5. 4. Validität und schriftliche Sprachkompetenz : Eine Studie zur Bewertung schriftlicher Leistungen im Fach Deutsch an schwedischen Schulen

   Författare :Maria Håkansson Ramberg; Frank Thomas Grub; Gudrun Erickson; Eva Breindl; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; L2 writing assessment; validity; modern foreign language; L2 German; Swedish upper secondary school; Common European Framework of Reference for Languages CEFR ; language education; Tyska; German;

   Sammanfattning : Validity is a fundamental aspect of quality within the field of testing and assessment. Despite this fact, little research has been conducted on the validity of written assessment in a Swedish educational context and even less regarding assessment in an additional foreign language.

7. 5. Quantifying neurodegeneration from medical images with machine learning and graph theory

   Författare :Gustav Mårtensson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Neurodegeneration (or brain atrophy) is part of the pathological cascade of Alzheimer’s disease (AD) and is strongly associated with cognitive decline. In clinics, atrophy is measured through visual assessments of specific brain regions on medical images according to established rating scales. LÄS MER
