  1. 1. Sexual conflict and male-female coevolution in the fruit fly

    Författare :Urban Friberg; Göran Arnqvist; Daniel Promislow; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cryptic male mate choice; Drosophila melanogaster; female mate choice; multiple mating; sexual conflict; sexually antagonistic coevolution; sexual selection; speciation; sperm competition; Biology; Biologi;

    Sammanfattning : Harmony and cooperation was for long believed to dominate sexual interactions. This view slowly started to change 25 years ago and is today replaced with a view where males and females act based on what is best from a costs-benefits perspective. LÄS MER

  2. 2. The genetic architecture of sexual dimorphism

    Författare :Robert Griffin; Urban Friberg; Alexei Maklakov; Jon Ågren; Russell Bonduriansky; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; evolution; intralocus sexual conflict; sex chromosomes; sexually antagonistic selection; sexual dimorphism;

    Sammanfattning : Phenotypic differences between the sexes evolve largely because selection favours a different complement of traits in either sex. Theory suggests that, despite its frequency, sexual dimorphism should be generally constrained from evolving because the sexes share much of their genome. LÄS MER

  3. 3. The effects of deleterious mutations on ageing

    Författare :Martin Iinatti Brengdahl; Urban Friberg; Dominic Wright; Thomas Flatt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ageing; Age-specific effects; Deleterious mutations; Drosophila melanogaster; Lifespan; Sex differences;

    Sammanfattning : Ageing is defined as the deterioration of an individual's physiological performance with advancing age, which leads to a decrease in reproduction and/or survival. The question why most organisms age has preoccupied humans for millennia and, over the last decades, resulted in an ever-increasing research effort to understand this phenomenon. LÄS MER

  4. 4. Den verkliga staden? : Norrköpings innerstad mellan urbana idéer och lokala identiteter

    Författare :Mats Brusman; Tora Friberg; Lars Kvarnström; Ola Wetterberg; Linköpings universitet; []
    Nyckelord :Town planning; place; transport; mindscapes; local identity; Stadsplanering; trafik; plats; mobilitet; mindscapes; lokal identitet; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : This dissertation studies how city planning is affected by notions on urbanity and ideas of the value of local places. Empirically, the dissertation deals with the development of the city of Norrköping in the 1990’s and the early 2000’s. LÄS MER

  5. 5. Sound perception and design in multimodal environments

    Författare :PerMagnus Lindborg; Anders K. Friberg; Daniel Västfjäll; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sound; perception; design; multimodal; environment; soundscape; music; listening; crossmodal; psychoacoustics; psychophysiology; personality trait; emotion; appraisal; aesthetics; colour; correlation; regression; classification; sonification; Tal- och musikkommunikation; Speech and Music Communication;

    Sammanfattning : This dissertation is about sound in context. Since sensory processing is inherently multimodal, research in sound is necessarily multidisciplinary. The present work has been guided by principles of systematicity, ecological validity, complementarity of  methods, and integration of science and art. LÄS MER
