    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical modelling; Sexually transmitted infections; Egocentric network analysis; Dynamic networks; Sexual behaviour; HIV; Statistical inference; Mathematical Statistics; matematisk statistik;

    Sammanfattning : In this thesis we develop statistical and mathematical models to study different factors of relevance for the spread of sexually transmitted infections (STIs). Two special interest groups for STI interventions are considered: sexually active youths and men who have sex with men (MSM). LÄS MER

    Sammanfattning : Most epidemiologic studies of sexually transmitted diseases (STD) are based on patients seeking help or advice at various health care settings. Because many STD:s are subclinical, epidemiologic surveys can be strengthened by a population-based approach. LÄS MER

  7. 5. Cryptic Female Choice and Male Mating Behaviour : Sexual Interactions in Beetles

    Författare :Martin Edvardsson; Göran Arnqvist; Paul Ward; Uppsala universitet; []

    Sammanfattning : The importance of cryptic female choice, i.e. female post-copulatory influence over male reproductive success, in driving the evolution of male traits remains controversial. The main aim of this thesis was to understand the post-copulatory consequences of sexual interactions and the importance of cryptic female choice in two species of beetle. LÄS MER
