  1. 6. Evolutionary consequences of maternal effects and stress

    Författare :Piotr K. Rowiński; Björn Rogell; Karl Gotthard; Katja Räsänen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parental effects; meta-analysis; development time; bet-hedging; brain size; evolutionary potential; unpredictable environments; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Maternal effects occur when maternal environment or phenotype influence offspring phenotype, in addition to genetic contribution of the mother. As maternal effects often influence phenotypes that are under natural selection, they hence have evolutionary consequences. LÄS MER

  3. 7. International Outcomes of Total Hip Arthroplasty: Influence of Patient, Implant, and Surgical factors on Total Hip Arthroplasty Survivorship in Sweden, the US, and Australia

    Författare :Elizabeth W. Paxton; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total Hip Arthroplasty; International outcomes; Variation in clinical practices; Risk of hip arthroplasty revision; meta-analysis;

    Sammanfattning : Abstract Background Hip osteoarthritis (OA) is debilitating disease resulting in pain, stiffness, and reduced physical function. Although total hip arthroplasty (THA) is a successful treatment for OA, some THAs require revision surgery due to infection, dislocation, aseptic loosening, fracture and other reasons. LÄS MER

  4. 8. Investigation of the origin of the coronary artery calcification process and its relationship to the atherosclerotic cardiovascular disease

    Författare :George Koulaouzidis; Michael Henein; Katrine Åhlström Riklund; Jan Engvall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coronary artery calcification; ethnicity; South Asians; Caucasians; reproducibility; aortic valve calcification; mitral valve calcification; family history of coronary artery disease; natural history; coronary artery calcium score; meta-analysis;

    Sammanfattning : The objectives of this thesis are: a) To examine racial/ethnic differences in coronary artery calcification (CAC) and CAD, between symptomatic South Asians and Caucasians, matched for age, gender and conventional cardiovascular risk factors, b) To assess, using a meta-analysis model, the natural history of and stability of measurements of coronary artery calcium scoring (CACs) based on data collected from two large published trials: St Francis and EBEAT, c) To investigate the prevalence of coronary artery calcification in individuals with CT evidence for AVC, mitral valve calcification (MAC) or of both of them (AVC+MAC), d) To assess any potential association between premature CAD (..

  5. 9. Vocal Expression of Emotion : Discrete-emotions and Dimensional Accounts

    Författare :Petri Laukka; Patrik N. Juslin; Erik Börjesson; Roddy Cowie; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; speech; emotion; vocal expression; emotion dimensions; acoustic cues; categorical perception; nonverbal communication; speech synthesis; cross-cultural communication; decoding accuracy; emotion intensity; meta-analysis; discrete emotions; Psykologi; Psychology; Psykologi;

    Sammanfattning : This thesis investigated whether vocal emotion expressions are conveyed as discrete emotions or as continuous dimensions. Study I consisted of a meta-analysis of decoding accuracy of discrete emotions (anger, fear, happiness, love-tenderness, sadness) within and across cultures. LÄS MER

  7. 10. Individual consistency in bird migration

    Författare :YANNIS VARDANIS; Evolutionär ekologi; []
    Nyckelord :bird migration; telemetry; bird ringing; individual consistency; repeatability; site fidelity; routes; timing; annual cycle; meta-analysis;

    Sammanfattning : Slight differences, which appear in the individual animals of the same species and population have been recognised and appreciated ever since Darwin. These consistent intra-specific differences in animals have been considered very important because they are often inherited, and thus, provide the basic material for evolution to act on. LÄS MER
