1. 1. Computationally efficient methods in spatial statistics : Applications in environmental modeling

   Författare :David Bolin; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In this thesis, computationally efficient statistical models for large spatial environmental data sets are constructed. In the first part of the thesis, a method for estimating spatially dependent temporal trends is developed. A space-varying regression model, where the regression coefficients for the spatial locations are dependent, is used. LÄS MER

3. 2. Ecological interactions in human modified landscapes : Landscape dependent remedies for the maintenance of biodiversity and ecosystem services

   Författare :Arvid Bolin; Biodiversitet; []
   Nyckelord :Central place foraging; Agriculture; Competition; Ecosystem service; Species coexistence; bumble bees; landscape ecology; Biodiversity; Agri-environment scheme; Central place foraging; jordbruk; konkurrens; landskaps ekologi; humlor; bin;

   Sammanfattning : Modern agricultural practices have led to an intensification of the agricultural landscape which has negatively affected both biodiversity and the ecosystem services it provides. In my thesis I have used ecological theory of optimal foraging to try and explain how landscape structure, landscape composition and agricultural management can explain the loss of biodiversity and how remedies can efficiently be implemented.

4. 3. Shifting Subordination : Co-located interprofessional collaboration betweenteachers and social workers

   Författare :Anette Bolin; Högskolan Väst; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; interprofessional collaboration; social work; teaching; professions; Social work; Socialt arbete; Socialt arbete; Social work; interprofessional collaboration; social work; teaching; professions; jurisdiction; subordination; discretion;

   Sammanfattning : The purpose of this thesis is to describe and analyse the practice processes involved in colocated interprofessional collaboration. The study took place in a resource school where social workers and teachers collaborate on an everyday basis around children who are both in receiptof special educational support and interventions from social services.

5. 4. The military profession in change : The case of Sweden

   Författare :Anna Bolin; Statsvetenskapliga institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Profession; professionalism; professionalisation; military; defence; security; attitudes; Sweden; interviews;

   Sammanfattning : The starting point for this study is the transformation that the latest decade has occurred in security and defence affairs. The focal point is the big challenges that these developments have implied for national armed forces. LÄS MER

7. 5. Models and Methods for Random Fields in Spatial Statistics with Computational Efficiency from Markov Properties

   Författare :David Bolin; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; random fields; Gaussian Markov random fields; Matérn covariances; stochastic partial differential equations; Computational efficiency;

   Sammanfattning : The focus of this work is on the development of new random field models and methods suitable for the analysis of large environmental data sets. A large part is devoted to a number of extensions to the newly proposed Stochastic Partial Differential Equation (SPDE) approach for representing Gaussian fields using Gaussian Markov Random Fields (GMRFs).
