  2. 1. Evolutionary consequences of dominance at the Brassicaceae self-incompatibility locus

    Author : Jörg Alexander Bachmann; Tanja Slotte; Vincent Castric; Ove Eriksson; Pär Ingvarsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Capsella; mating system shift; self-fertilization; self-incompatibility; small RNA; dominance; Arabidopsis; population genetics; genomics; gene expression; ekologi och evolution; Ecology and Evolution;

    Abstract : Self-incompatibility (SI) is a genetic mechanism that allows plants to enforce outcrossing by rejecting self-pollen and pollen from close relatives. In the Brassicaceae, SI is sporophytic and controlled by the self-incompatibility locus (S-locus). READ MORE

  4. 2. Sex and violence in lobsters - a smelly business

    Author : Malin Skog; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dominance; urine signals; recognition; Aggressive behaviours; intermoult mating; sexual dimorphism; European lobster; chemical communication; Homarus gammarus; aesthetasc morphology;

    Abstract : The aim of this thesis was to study the chemical communication involved in aggressive and reproductive behaviours in the European lobster (Homarus gammarus). Both male and female H. gammarus established and maintained dominance, but the sexes used different strategies for dominance maintenance. READ MORE

  5. 3. Methods for interval-censored data and testing for stochastic dominance

    Author : Angel G. Angelov; Magnus Ekström; Maria Karlsson; Bengt Kriström; Per Johansson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interval-censored data; Informative censoring; Self-selected intervals; Questionnaire-based studies; Maximum likelihood; Permutation test; Two-sample test; Stochastic dominance; Four-decision test; Statistics; statistik;

    Abstract : This thesis includes four papers: the first three of them are concerned with methods for interval-censored data, while the forth paper is devoted to testing for stochastic dominance.In many studies, the variable of interest is observed to lie within an interval instead of being observed exactly, i.e. READ MORE

  6. 4. War and Unreason. Bounded Learning Theory and War Duration

    Author : Marco Nilsson; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; war duration; security dilemma; offense-defense balance; offensive expectations; offense dominance; defense dominance; Winter War; Continuation War; Iran-Iraq War; Indo- Pakistani War; ideas; rational choice; expected utility; war; bounded learning theory.; war duration;

    Abstract : Why are some wars longer than others? Offense-defense theorists have assumed that wars are shorter and it is more difficult for states to create security when military technology favors the offense and attacking is easier than defending. This study argues that this assumption is wrong on both accounts. READ MORE

  7. 5. Nandrolone decanoate, behaviour and brain: animal experimental studies

    Author : Ann-Sophie Lindqvist; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agression; alcohol intake; anabolic steroids; dominance; ethanol intakie; fleeing and freezing behaviours;

    Abstract : Abstract: Abuse of anabolic androgenic steroids (AAS) has been linked to psychiatric and physiological complications in humans. Studies have further found a relationship between AAS abuse and abuse of alcohol and other drugs. READ MORE
