  1. 1. Kön i förändring : Den svenska könsrollsforskningen 1959-1979

    Författare :Jenny-Leontine Olsson; Elisabeth Mansén; Ulla Manns; Elisabeth Elgán; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Sex Role Research; Edmund Dahlström; Harriet Holter; Rita Lijleström; Equality Policy; Nordic Egalitarianism; History of science and ideas; Idé- o lärdomshistoria; idéhistoria; History of Ideas;

    Sammanfattning : This doctoral thesis analyzes Swedish sex role research between 1959 and 1979. The focal point of the analysis is how researchers reshaped ideas about sex/gender. This process is put in relation to the political context which affected and was affected by such ideas. LÄS MER

  3. 2. Reproductive physiology of the female three-spined stickleback, Gasterosteus aculeatus

    Författare :Chrysoula Roufidou; Bertil Borg; Geir Lasse Taranger; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; overripening of eggs; spawning cycle; brain-pituitary-gonad BPG axis; vitellogenin; ovarian fluid; sex steroids; reproduction; three-spined stickleback; Gasterosteus aculeatus; fish; funktionell zoomorfologi; Functional Zoomorphology;

    Sammanfattning : Reproduction in vertebrates, including fishes, is under control of the brain-pituitary-gonad (BPG) axis. The female three-spined stickleback, Gasterosteus aculeatus, produces egg clutches at intervals of a few days and spawns them in a nest built by male. LÄS MER

  4. 3. Splitting the sexes : The birth and senescence of sex chromosomes

    Författare :Aivars Cirulis; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome; Sexual conflict; Macrostomum lignano; Experimental evolution; Genomics of sex;

    Sammanfattning : The evolution of gonochorism from hermaphroditism can be gradual by increasing investment in one sex role while decreasing in the other, or rapid through the fixation of sex-role sterility mutations, eventually leading to the evolution of sex chromosomes. It is expected that the transition will involve a temporary state of gynodioecy or androdioecy as the mutations are not expected to take place at the same time. LÄS MER

  5. 4. Depression among Swedish 70-year-olds - Sex differences from a gender perspective

    Författare :Therese Rydberg Sterner; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; depression; time trend; epidemiology; sex; gender; experiences; older adults;

    Sammanfattning : Depression is one of the leading causes of global burden of disease. Due to increased life expectancy, late-life depression is an escalating public health issue. The prevalence is reported to be almost twice as high among women compared to men. LÄS MER

  7. 5. Sex Chromosome Evolution in a Hermaphrodite : Genetic and phenotypic relationships between sex roles

    Författare :Anna Nordén; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome evolution; Hermaphrodite; Inter-sexual genetic correlation; Quantitative genetics; Macrostomum lignano; Experimental evolution; Sexual conflict;

    Sammanfattning : Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. LÄS MER
