2. 1. Making Sense of Negative Numbers

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

5. 3. Making Sense of Antisense

   Author : Johan Reimegård; Gerhart Wagner; Hanah Margalit; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Mathematical Learning Disability : Cognitive Conditions, Development and Predictions

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

   Abstract : 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.

7. 5. Magnitude Processing in Developmental Dyscalculia : A Heterogeneous Learning Disability with Different Cognitive Profiles

   Author : Kenny Skagerlund; Ulf Träff; Thomas Karlsson; Bert De Smedt; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Developmental Dyscalculia; mathematical learning disabilities; number sense; Dyskalkyli; matematiksvårigheter; antalsuppfattning;

   Abstract : Developmental dyscalculia (DD) is a learning disability that is characterized by severe difficulties with acquiring age-appropriate mathematical skills that cannot be attributed to insufficient education, language skills, or motivation. The prevalence rate is estimated at 3-6%, meaning that a substantial portion of the population struggles to learn mathematics to such a large degree that it affects overall well-being and academic prospects.
