  1. 1. Future generations : A challenge for moral theory

    Författare :Gustaf Arrhenius; Uppsala universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Philosophy; future generations; population theory; population ethics; axiology; welfare; moral theory; social choice theory; impossibility theorems; Filosofi; Practical philosophy; Praktisk filosofi; Practical Philosophy; Praktisk filosofi;

    Sammanfattning : For the last thirty years or so, there has been a search underway for a theory that canaccommodate our intuitions in regard to moral duties to future generations. The object ofthis search has proved surprisingly elusive. The classical moral theories in the literature allhave perplexing implications in this area. LÄS MER

  2. 2. Markov Chains, Renewal, Branching and Coalescent Processes : Four Topics in Probability Theory

    Författare :Andreas Nordvall Lagerås; Thomas Höglund; Ingemar Kaj; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Sammanfattning : This thesis consists of four papers.In paper 1, we prove central limit theorems for Markov chains under (local) contraction conditions. As a corollary we obtain a central limit theorem for Markov chains associated with iterated function systems with contractive maps and place-dependent Dini-continuous probabilities. LÄS MER

  3. 3. Game Theory and Agents

    Författare :Stefan J. Johansson; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Game Theory; Multi-Agent Systems; No Free Lunch Theorem; Characteristic Distributions;

    Sammanfattning : A fundamental problem in multi agent systems is conflict resolution. A conflict occurs in general when the agents have to deal with inconsistent goals, such as a demand for shared resources. We investigate how a game theoretic approach may be a helpful and efficient tool in examining a class of conflicts in multi agent systems. LÄS MER

  4. 4. Inbreeding, Effective Population Sizes and Genetic Differentiation : A Mathematical Analysis of Structured Populations

    Författare :Fredrik Olsson; Ola Hössjer; Steinar Engen; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; matematisk statistik; Mathematical Statistics;

    Sammanfattning : This thesis consists of four papers on various aspects of inbreeding, effective population sizes and genetic differentiation in structured populations, that is, populations that consist of a number of subpopulations. Three of the papers concern age structured populations, where in the first paper we concentrate on calculating the variance effective population size (NeV) and how NeV depends on the time between measurements and the weighting scheme of age classes.

  5. 5. Kameran i krig : den fotografiska iscensättningen av Vietnamkriget i svensk press

    Författare :Kari Andén-Papadopoulos; Peter Larsen; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; war photography; Vietnam war; media; visual communication; documentary photography; photo history; photo theory; Sweden; gender theory; masculinity; femininity; postcolonial theory; cultural studies; ideologies; medie- och kommunikationsvetenskap; Media and Communication Studies;

    Sammanfattning : The doctoral thesis deals with the problems of (news) photographic representation in general, and is based on an empirical study ofVietnam War photography in four major Swedish daily newspapers. A more specific aim of the thesis is to investigate and ideologically evaluate the representational strategies of the press photographs. LÄS MER
