  1. 1. From Penicillin Binding Proteins to Community Interventions : Mathematical and Statistical Models Related to Antibiotic Resistance

    Författare :Patricia Geli Rolfhamre; Åke Svensson; Mikael Andersson; Dan I. Andersson; Karl Ekdahl; Bruce R. Levin; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; antibiotic resistance; mathematical modeling; pharmacokinetics; pharmacodynamics; penicillin binding protein; postantibiotic effect; reversibility; selection; community intervention; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Sammanfattning : Antibiotic resistance has become a major public health concern and mathematical models are important analytical tools for the understanding, evaluation and prediction of the resistance problem and related control strategies.The risk of emerging antibiotic resistance and selection has rarely been a concern in the design of antibiotic drug dosing regimens.

  3. 2. Prostate cancer incidence, treatment and mortality : Empirical longitudinal register-based studies and methods for handling missing data

    Författare :Marcus Westerberg; Rolf Larsson; Hans Garmo; Pär Stattin; Jimmy Olsson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; statistics; mathematics; prostate cancer; missing data; survival analysis; longitudinal models; incidence; treatment; mortality; Mathematical Statistics; Matematisk statistik; Statistics; Statistik; Urologi; Urology; Epidemiologi; Epidemiology;

    Sammanfattning : The diagnostic activity for prostate cancer has increased substantially in Sweden, primarily due to increased use of prostate-specific antigen (PSA) testing in asymptomatic men, and this has led to a large increase in diagnoses. There have also been changes in the diagnostic workup, guidelines, treatment strategies, and more effective treatments have been introduced in different phases of the disease. LÄS MER

  4. 3. Mathematical Reasoning : In physics and real-life context

    Författare :Helena Johansson; Mats Andersson; Jesper Boesen; Morten Blomhøj; Göteborgs universitet; Göteborgs universitet; Gothenburg University; Göteborgs universitet; Gothenburg University; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; Creative mathematical reasoning; Descriptive statistics; Differential item functioning; Figurative context; Imitative reasoning; Mathematical Reasoning Requirements; Mathematics tasks; National tests; Physics tasks; Real-life context; T-test; Upper secondary school; Creative mathematical reasoning;

    Sammanfattning : This thesis is a compilation of four papers in which mathematical reasoning is examined in various contexts, in which mathematics is an integral part. It is known from previous studies that a focus on rote learning and procedural mathematical reasoning hamper students’ learning of mathematics. LÄS MER

  7. 5. Perfect simulation of some spatial point processes

    Författare :Kajsa Larson; Olle Häggström; Chalmers University of Technology and Göteborg University Department of Mathematical Statistics; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Perfect simulering; coupling from the past; Markov shain Monte Carlo; point process; Widom-Rowlinson model; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Sammanfattning : Coupling from the past (CFTP) algorithms are presented that generate perfectly distributed samples from the multi-type Widom--Rowlinson (W--R) model and some generalizations of it. The classical W--R model is a point process in the plane or the  space consisting of points of several different types. LÄS MER
