1. 1. Generative models for action generation and action understanding

   Författare :Judith Bütepage; Danica Kragic; Ivan Laptev; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; Datalogi;

   Sammanfattning : The question of how to build intelligent machines raises the question of how to rep-resent the world to enable intelligent behavior. In nature, this representation relies onthe interplay between an organism’s sensory input and motor input. Action-perceptionloops allow many complex behaviors to arise naturally. LÄS MER

3. 2. Evidence for adaptive variation at the genes coding for cytosolic phosphoglucose isomerase (PGIC) in Festuca ovina L

   Författare :Yuan Li; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3-D protein structure; purifying selection; positive selection; cDNA sequences; local adaptation; alvar grasslands; Festuca ovina; Phosphoglucose isomerase; PgiC loci; SNPs; nucleotide polymorphism; horizontal gene transfer;

   Sammanfattning : The gene (Pgi) encoding the enzyme phosphoglucose isomerase (PGI) which plays a central role in the main pathways of carbon metabolism has been shown to be of adaptive significance in a wide range of different species. Earlier studies of enzyme electromorph variation in the grass Festuca ovina suggest that variation in cytosolic PGI (PGIC) may be involved in the adaptive response of F. LÄS MER

4. 3. Measuring the Unobservable: Selecting Which Managers for Higher Hierarchical Levels

   Författare :Anna Stafsudd; Företagsekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Företagsledning; management; Management of enterprises; homosocial reproduction; tournament theory; top management; selection; recruitment;

   Sammanfattning : Recruitment and selection of managers is to a large degree characterized by information uncertainty. Managers’ performance is difficult to evaluate, as their responsibility consists of so many different aspects, as they may not always be observed due to need for freedom of action and as their work is affected by factors in their environment, which are outside of their control.

5. 4. Communication in Games and Decision Making under Risk

   Författare :Erik Wengström; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Communication; Repeated Bertrand Games Cooperation; Renegotiation; Experiments; Risk Aversion; Non-cooperative Game Theory; Selection; Loss Aversion; Timing of Uncertainty Resolution;

   Sammanfattning : This thesis is divided into two distinct parts. The first part studies communication in games and the second part investigates individual decision making under risk. Chapters 2 – 4, co-authored with Ola Andersson, investigate communication and renegotiation in dynamic games. LÄS MER

7. 5. Problem eller tillgång? En studie om social och etnisk mångfald i högskolan

   Författare :Thérèse Hartman; Christina Gustafsson; Johanna Esseveld; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Higher education; ethnicity; class; democracy; equality; selection; recruitment; redistribution; Education; Pedagogik; pedagogik; Education;

   Sammanfattning : The general problem I am addressing concerns the role of the university as an actor for increased equality and democracy. How does this role manifest itself in selecting and recruiting students to the university and how does it influence teaching? The aim of my empirical study is to describe and understand processes and contexts where ethnicity and class are important. LÄS MER
