  1. 1. Model-Based Hypothesis Testing in Biomedicine : How Systems Biology Can Drive the Growth of Scientific Knowledge

    Författare :Rikard Johansson; Gunnar Cedersund; Tomas Strömberg; Peter Strålfors; Marija Cvijovic; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; systems biology; modeling; ODE; hypothesis testing; falsificationism; insulin signaling; yeast; population heterogeneity; cell-to-cell variation; facilitation; pyramidal; synaptic; bootstrapping; personalized medicine; omics;

    Sammanfattning : The utilization of mathematical tools within biology and medicine has traditionally been less widespread compared to other hard sciences, such as physics and chemistry. However, an increased need for tools such as data processing, bioinformatics, statistics, and mathematical modeling, have emerged due to advancements during the last decades. LÄS MER

  3. 2. Method specific factors in personality tests

    Författare :Thomas Lindgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Two of the most widely used personality assessment methods are the Rorschach (Exner, 1993) and the MMPI/MMPI-2 (Hathaway & McKinley, 1943; 1989). Both methods have demonstrated validity for particular purposes (Meyer & Archer, 2001). LÄS MER

  4. 3. Tests for systematic effects in supernova cosmology

    Författare :Serena Nobili; Ariel Goobar; Bruno Leibundgut; Stockholms universitet; []
    Nyckelord :Cosmology; supernovae; astrophysics;

    Sammanfattning : Type~Ia supernovae are used as standard candles to measure the energy density components of the universe. This led to the new paradigm in cosmology: only about 30\% of the universe is made by ordinary pressure-less matter, the rest is associated with an unknown form of energy with a negative equation of state parameter, called dark energy, able to drive the accelaration of the universe.

  5. 4. Relativizing linguistic relativity : Investigating underlying assumptions about language in the neo-Whorfian literature

    Författare :Ingrid Björk; Åke Viberg; Pär Segerdahl; Talbot J. Taylor; Uppsala universitet; []
    Nyckelord :Linguistics; Linguistic relativity hypothesis; Sapir-Whorf hypothesis; Language and thought; Neo-Whorfianism; Lingvistik; Linguistics; lingvistik;

    Sammanfattning : This work concerns the linguistic relativity hypothesis, also known as the Sapir-Whorf hypothesis, which, in its most general form claims that ‘lan-guage’ influences ‘thought’. Past studies into linguistic relativity have treated various aspects of both thought and language, but a growing body of literature has recently emerged, in this thesis referred to as neo-Whorfian, that empirically investigates thought and language from a cross-linguistic perspective and claims that the grammar or lexicon of a particular language influences the speakers’ non-linguistic thought.

  7. 5. On Confidence Intervals and Two-Sided Hypothesis Testing

    Författare :Måns Thulin; Silvelyn Zwanzig; Burkhardt Seifert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics; Matematisk statistik;

    Sammanfattning : This thesis consists of a summary and six papers, dealing with confidence intervals and two-sided tests of point-null hypotheses.In Paper I, we study Bayesian point-null hypothesis tests based on credible sets. A decision-theoretic justification for tests based on central credible intervals is presented. LÄS MER
