  1. 6. Matematisk och pedagogisk kunskap – Lärarstudenters uppfattningar av begreppen funktion och variabel

    Författare :Mikael Borke; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; function; variable; student teacher; concept definition; concept image; conception; mathematical knowledge for teaching; function;

    Sammanfattning : The concepts of function and variable are important in compulsory and upper secondary schools, and at the university. Teachers' mathematical knowledge, as well as their pedagogical knowledge, have an effect on their teaching. LÄS MER

  3. 7. Death, survival, and morphological development of hippocampal granule cells born in an inflammatory environment

    Författare :Sara Bonde; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microglia; hippocampus; Adult neurogenesis; gephyrin; dendritic spines;

    Sammanfattning : The brain continues to form new neurons throughout life. This process of adult neurogenesis has been thoroughly documented in several species including birds, rodents and humans. LÄS MER

  4. 8. Overconfidence and Format Dependence in Subjective Probability Intervals: Naive Estimation and Constrained Sampling

    Författare :Patrik Hansson; Peter Juslin; Carl Martin Allwood; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : A particular field in research on judgment and decision making (JDM) is concerned with realism of confidence in one’s knowledge. An interesting finding is the so-called format dependence effect which implies that assessment of the same probability distribution generates different conclusions about over- or underconfidence bias depending on the assessment format.

  5. 9. Neurotrophic factors and neuronal plasticity

    Författare :Sten Linnarsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The neurotrophic factors were originally discovered because of their ability to rescue neurons during a period of naturally occurring programmed cell death. This gave rise to the neurotrophic factor hypothesis which states that specific target-derived factors protect and support subpopulations of innervating neurons, thereby regulating the pattern and quantity of innervation properly for each target tissue.

  7. 10. How do metamorphic fluids move through rocks? : An investigation of timescales, infiltration mechanisms and mineralogical controls

    Författare :Barbara I. Kleine; Alasdair D. L. Skelton; John C. Schumacher; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metamorphic fluid flow; fluid-rock interaction; fluid infiltration mechanisms; fluid flux rates; thermodynamic modeling; reaction front propagation; fluid flux calculation; Geology; geologi;

    Sammanfattning : This thesis aims to provide a better understanding of the role of mountain building in the carbon cycle. The amount of CO2 released into the atmosphere due to metamorphic processes is largely unknown. LÄS MER
