  2. 1. Teaching genetics - a linguistic challenge : A classroom study of secondary teachers' talk about genes, traits and proteins

    Author : Karin Thörne; Niklas Gericke; Anders Arnqvist; Ute Harms; Karlstads universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Science education; teaching genetics; teachers talk; mendelian genetics; gene function; systemic functional linguistics; compulsory school; Biology; Biologi;

    Abstract : The overall aim of this thesis is to investigate how teachers talk about genetics in actual classroom situations. An understanding of how language is used in action can give detailed information about how the subject matter is presented to the students as well as insights in linguistic challenges. READ MORE

  4. 2. Linguistic Challenges in Science Education : A Classroom Study of Teachers’ and Students’ use of Central Concepts in Genetics

    Author : Karin Thörne; Niklas Gericke; Anders Arnqvist; Anat Yarden; Karlstads universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Classroom study; Classroom talk; Genetics education; Genetics concepts; Scientific language; Secondary school; Systemic Functional Linguistics; Thematic pattern analysis; Biology; Biologi;

    Abstract : This thesis examines linguistic aspects of genetics education and is based on the view that language is an essential dimension of teaching and learning. Its objective is to clarify how teachers and students use genetics concepts in real teaching situations. READ MORE

  5. 3. Spatial Statistics and Ancestral Recombination Graphs with Applications in Gene Mapping and Geostatistics

    Author : Linda Werner Hartman; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetik; Genetics; cytogenetics; cytogenetik; genetic association analysis; ancestral recombination graph Generalized linear mixed models; kriging; bilinear interpolation; Gaussian Markov random fields; Statistics;

    Abstract : This thesis explores models and algorithms in geostatistics and gene mapping. The first part deals with the use of computationally effective lattice models for inference of data with a continuous spatial index. READ MORE

  6. 4. Pointwise and Genomewide Significance Calculations in Gene Mapping through Nonparametric Linkage Analysis: Theory, Algorithms and Applications

    Author : Lars Ängquist; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; programming; actuarial mathematics; Statistik; cytogenetics; Genetik; cytogenetik; Mathematics; Matematik; Statistics; operations research; Genetics; ROC curves; conditioning loci; optimal score functions; noncentrality parameter; cost adjusted relative efficiency; exponential tilting; importance sampling; Monte Carlo simulation; normal approximation; crossover rate; process maximum; analytical approximation; significance calculations; NPL score; conditional linkage analysis; two-locus linkage analysis; Allele sharing; aktuariematematik; operationsanalys; programmering; gene-gene interaction; composite hypotheses; genetic disease models; classes of score functions; nonparametric linkage analysis;

    Abstract : In linkage analysis or, in a wider sense, gene mapping one searches for disease loci along a genome. This is done by observing so called marker genotypes (alleles) and phenotypes (affecteds/unaffecteds) of a pedigree set, i.e. READ MORE

  7. 5. Cobalamin communication in Sweden 1990 – 2000 : views, knowledge and practice among Swedish physicians

    Author : Mats Nilsson; Johan Lökk; Göran Westman; Bo Norberg; Kurt Svärdsudd; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Cobalamin; folate; iron; homocysteine; MMA; vitamin B12 deficiency; therapy tradition; drug epidemiology; communication; receivers; senders; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; medicin; Medicine;

    Abstract : Cobalamin (vitamin B12) is one of several essential micronutrients needed by the human organism. Other important micronutritients, which interplay with vitamin B12, are folate and iron. During the last ten years, the attention has been drawn to different forms of neurological disorders supposed to be caused by vitamin B12 deficiency. READ MORE
