  1. 1. Living in a Variable Environment : Reproductive Decisions in Wild Bird Populations

    Author : Mårten B. Hjernquist; Lars Gustafsson; Marcel Visser; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary ecology; competition; sex allocation; paternity; EPP; inadvertent social information; migration; breeding density; territory quality; territory availability; great tit; blue tit; Ficedula albicollis; Biology; Biologi; Animal Ecology; zooekologi;

    Abstract : In nature, environments are often variable and heterogeneous influencing ecological and evolutionary processes. This thesis focus on how animals interact with their environment and how that affects the reproductive decisions they make. READ MORE

  2. 2. Set Constraints for Local Search

    Author : Magnus Ågren; Pierre Flener; Justin Pearson; Gilles Pesant; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; combinatorial problems; constraint-based local search; constraint-directed search; constraint programming; incremental algorithms; monadic existential second-order logic; neighbourhoods; penalty; set variables; set constraints; variable conflicts; Computer science; Datavetenskap; Datavetenskap; Computer Science;

    Abstract : Combinatorial problems are ubiquitous in our society and solving such problems efficiently is often crucial. One technique for solving combinatorial problems is constraint-based local search. Its compositional nature together with its efficiency on large problem instances have made this technique particularly attractive. READ MORE

  3. 3. Estimation of Nonlinear Latent Variable and Mixture Models

    Author : Johan Vegelius; Shaobo Jin; Fan Yang-Wallentin; Melanie Wall; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; structural equation modeling; semiparametric; EM algorithm; adaptive Gauss-Hermite quadrature approximation; Laplace approximation; zero inflation; Statistics; Statistik;

    Abstract : In this thesis methods are developed for estimation of latent variable models. In particular nonlinear structural equation models are estimated in the presence of ordinal data and mixture models for count data. READ MORE

  4. 4. Passing the open windows : A quantitative and qualitative approach to immediate military balance and escalation of protracted conflicts

    Author : Björn Holmberg; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Peace and conflict research; Window of opportunity; realism; balance of power; rational choice; organizationtheory; learning; Freds- och konfliktforskning; Peace and conflict research; Freds- och konfliktforskning; Peace and Conflict Research; freds- och konfliktforskning;

    Abstract : This dissertation has a dual point of departure: first, the widely known concept of window of opportunity and its application in the study of international relations (IR) and, second, the notion among modern classical realists that states maximize their power and, hence, that windows of opportunity should increase the probability of escalation to war or escalation of a war.The focus is primarily on the effects of rapid power shifts in dyads of non-great powers experiencing protracted conflict.

  5. 5. Common cranes in agricultural landscapes : linking space use and foraging patterns to conservation and damage prevention

    Author : Lovisa Nilsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Many populations of migratory cranes, geese and swans are increasing throughout Europe and North America. During migration, these birds congregate at staging sites, often located in landscapes with both wetlands and arable land. READ MORE
