1. 1. Making Sense of Negative Numbers

   Författare :Cecilia Kilhamn; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; metaphor; signed number; negative number; number sense; case study; longitudinal; social constructivism;

   Sammanfattning : Numbers are abstract objects that we conceptualize and make sense of through metaphors. When negative numbers appear in school mathematics, some properties of number sense related to natural numbers become contradictory. The metaphors seem to break down, making a transition from intuitive to formal mathematics necessary. LÄS MER

3. 2. Att skapa mening i en komplex praktik : Föreställningar om brottspreventiva samverkansformer mellan omsorg och kontroll

   Författare :Christina Söderberg; Martin Börjeson; Magnus Dahlstedt; Karin Osvaldsson; Kerstin Johansson; David Wästerfors; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Crime prevention; Individual-oriented interaction; Prevention of youth crime; Youth at risk of crime; Sense-making; Institutional logics; Human service organisations; Social control;

   Sammanfattning : This thesis deals with individual-oriented crime prevention interaction (ICPI) aimed at young people who commit - or are deemed to be at risk of committing - offences. Youth crime prevention is always topical, and a great deal of attention has been paid to such initiatives in recent years. LÄS MER

4. 3. Sensing and Making Sense : Designing Middleware for Context Aware Computing

   Författare :Martin Jonsson; Carl Gustaf Jansson; Anind K. Dey; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap;

   Sammanfattning : Computing devices are becoming wireless, smaller and embedded into other artifacts. Some of them are mobile while others are built into the environment. The novel technologies are also becoming more dependent of communication with other computing devices over different kinds of networks. LÄS MER

5. 4. Making Sense of Antisense

   Författare :Johan Reimegård; Gerhart Wagner; Hanah Margalit; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sRNA; miRNA; RNA; target prediction; SOLiD siRNA; E.coli; D.discoideum; Biology; Biologi; Bioinformatics; Bioinformatik; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

   Sammanfattning : RNA is a highly versatile molecule with functions that span from being a messenger in the transfer from DNA to protein, a catalytic molecule important for key processes in the cell to a regulator of gene expression. The post-genomic era and the use of new techniques to sequence RNAs have dramatically increased the number of regulatory RNAs during the last decade. LÄS MER

7. 5. Mathematical Learning Disability : Cognitive Conditions, Development and Predictions

   Författare :Rickard Östergren; Ulf Träff; Joakim Samuelsson; Örjan Dahlström; Åke Olofsson; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematical learning disability; dyscalculia; mathematical cognition; number sense; Matematiska inlärningssvårigheter; dyskalkyli; matematisk kognition; antalsuppfattning;

   Sammanfattning : The purpose of the present thesis was to test and contrast hypotheses about the cognitive conditions that support the development of mathematical learning disability (MLD). Following hypotheses were tested in the thesis: a) domain general deficit, the deficit is primarily located in the domain general systems such as the working memory, b) number sense deficit, the deficit is located in the innate approximate number system (ANS), c) numerosity coding deficit, the deficit is located to a exact number representation system, d) access deficit, the deficit is in the mapping between symbols and the innate number representational system (e.
