  1. 1. Population viability analysis for plants practical recommendations and applications

    University dissertation from Stockholm : Botaniska institutionen

    Author : Satu Ramula; Stockholms universitet.; Södertörns högskola.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; demography; matrix population models; population viability analysis; population growth rate; stochastic models;

    Abstract : Population viability analysis (PVA) is commonly used in conservation biology to predict population viability in terms of population growth rate and risk of extinction. However, large data requirements limit the use of PVA for many rare and threatened species. READ MORE

  2. 2. Population Genetic Methods and Applications to Human Genomes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lucie Gattepaille; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Population genetics; Human evolution; Genetic diversity; Genetic differentiation; Adaptation; Population structure; Effective population size; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Population Genetics has led to countless numbers of fruitful studies of evolution, due to its abilities for prediction and description of the most important evolutionary processes such as mutation, genetic drift and selection. The field is still growing today, with new methods and models being developed to answer questions of evolutionary relevance and to lift the veil on the past of all life forms. READ MORE

  3. 3. Collaboration and Coordination Challenges in Patient-Centered Care Models and Informaion Services

    University dissertation from Stockholm : Department of Computer and Systems Sciences, Stockholm University

    Author : Monica Winge; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; patient-centered care; healthcare; social care; home care; collaboration; coordination; care processes; processes coordination; multi-sectoral collaboration; communication; information models; information services; management; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : This thesis reports on research focuses on how to deal with the fact that the organization and processesof today’s health and social care are becoming ever more complex as a consequence of societal trends, including an aging population and an increased reliance on care at home. The overall research goal is to suggest ways in which IT-based solutions can enable and leverage collaboration and coordination insituations where a co-morbid patient is subject to care delivered simultaneously by several different professionals and organizations.

  4. 4. Stochastic Epidemic Models Different Aspects of Heterogeneity

    University dissertation from Stockholm : Department of Mathematics, Stockholm University

    Author : Mathias Lindholm; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Abstract : This thesis is concerned with the study of stochastic epidemic models for infectious diseases in heterogeneous populations. All diseases treated are of SIR type, i.e. individuals are either Susceptible, Infectious or Recovered (and immune). READ MORE

  5. 5. A contribution to population dynamics in space

    University dissertation from Umeå : Umeå universitet

    Author : Nikias Sarafoglou; Umeå universitet.; [1987]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Population growth; population age structure; migration; labour market; housing market; production function; stochastic differential equations; partial differential equations;

    Abstract : Population models are very often used and considered useful in the policy-making process and for planning purposes. In this research I have tried to illuminate the problem of analysing population evolution in space by using three models which cover a wide spectrum of complementary methodologies:a The Hotell.
