1. 1. Kamrateffekter i skolundervisning – En ramfaktorteoretisk analys

   Författare :Pontus Bäckström; Sangeeta Bagga-Gupta; Rebecka Florin Sädbom; Vezir Aktaş; Ulf P. Lundgren; Jönköping University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; compositional effects; peer effects; frame factor theory; structural equation modelling;

   Sammanfattning : In the educational literature on peer effects, attention has been brought to the fact that the mechanisms creating peer effects are still to a large extent hidden in obscurity. The hypothesis in this study is that the Frame Factor Theory can be used to explain these mechanisms. LÄS MER

3. 2. Exploring mechanisms of peer effects in education : Frame factor analyses of classroom instruction

   Författare :Pontus Bäckström; Jesper Boesen; Charlotta Mellander; Jan-Eric Gustafsson; Jönköping University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Despite a vast international literature, previous research into compositional effects and peer effects in education has remarked on the lack of consensus within the field. To date, peer effects in education and students’ different opportunities to learn in school have been studied separately. LÄS MER

4. 3. Bureaucracy, Informality and Taxation : Essays in Development Economics and Public Finance

   Sammanfattning : This thesis consists of three self-contained essays.Essay 1, "Dispatchers", is a study of a specialized service sector that has arisen in many developing countries.It is a well-established fact that the government bureaucracy in many developing countries is large, difficult to understand, non-transparent and time-consuming.

5. 4. Designing the Edge : An Inquiry into the Psychospatial Nature of Meaning in the Architecture of the Urban Waterfront

   Författare :Konstantinos Ioannidis; Katja Grillner; Lars-Henrik Ståhl; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban design and theory; spatial psychology; spatial meaning; compositional strategies; formulative logic; waterfront design and spatial organization; psychospatial reading; transformational relations; design of the edge; Architecture; Arkitektur;

   Sammanfattning : The initial goal of this effort is to develop a discussion on urban design process and thinking that acknowledges the needs of places with meaning in the design of the urban waterfront. The thesis addresses the fact that the problematic of the coastal formulation is intricate, comprising not only aspects related to the spatial organization and design of its domain but also shared properties originated by the presence and movement of the perceiving subject in the area.

7. 5. Reconstruction of Past European Land Cover Based on Fossil Pollen Data : Gaussian Markov Random Field Models for Compositional Data

   Författare :Behnaz Pirzamanbein; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spatial Statistics; Adaptive Markov Chain Monte Carlo; Dirichlet Observation; Confidence Region; Palaeoecology; Past Human Land Use; Stochastic Partial Differential Equation;

   Sammanfattning : The aim of this thesis is to develop statistical models to reconstruct past land cover composition and human land use based on fossil pollen records over Europe for different time periods over the past 6000 years. Accurate maps of past land cover and human land use are needed when studying the interaction between climate and land surface, and the effects of human land use on past climate. LÄS MER
