  1. 1. Tracing selection and adaptation along an environmental gradient in Populus tremula

    Författare :David Hall; Pär Ingvarsson; Thomas Bataillon; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Local adaptation; Selection; genetic differentiation; QST; FST; Association study; frequency spectra; recurrent hitchhiking; selective sweep; Tree; Populus; natural selection; quantitative genetics; Terrestrial ecology; Terrestrisk ekologi; Population Biology; populationsbiologi; genetik; Genetics;

    Sammanfattning : The distribution of the expressed genotype is moved around in the population over time byevolution. Natural selection is one of the forces that act on the phenotype to change the patterns ofnucleotide variation underlying those distributions. LÄS MER

  3. 2. Game of crops : genetic composition and adaptation of seed orchard crops

    Författare :Alisa Heuchel; Xiao-Ru Wang; David Hall; Ulfstand Wennström; Jaroslaw Burczyk; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; seed orchards; GBS; linear deployment; tree improvement; genetic diversity; adapation; topgrafting; Scots pine; Norway spruce; improved reforestation material; field performance; flowering stimulation; fertility variation; Genetics; genetik; environmental science; miljövetenskap;

    Sammanfattning : Orchard populations are artificial and intensively managed populations of elite, best-performing trees that are established for mass production of genetically improved seeds. Seed orchards connect cycles of selection, breeding, and testing of plus-trees with the deployment of the improved seeds at the operational plantations. LÄS MER

  4. 3. Self-Knowledge/Self-Regulation/Self-Control: A Ubiquitous Computing Perspective

    Författare :Lars Hall; Kognitionsvetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pervasive computing; affective computing; persuasive computing; Psychology; Psykologi; ubiquitous computing; computer-mediated extrospection; precommitment; distributed motivation; distributed cognition; neurofeedback; biofeedback; metacognition; brain-imaging; learning strategies; emotion regulation; mental strategies; verbal report; implicit learning; consciousness; introspection; self-control; Self-knowledge; self-regulation;

    Sammanfattning : This thesis is about self-knowledge, self-regulation and self-control. All three of these terms are easily understandable, and apply to situations in our daily lives (like misjudging one’s own competence at retiling the bathroom floor, or feeling the anxiety and thrill of doing unsupervised work, or guiltily hitting the snooze-button for the fifth time, and missing half a day of school).

  5. 4. IT-kvalitet i praxis: systemutvecklares kunskap om och syn på kvalitet

    Författare :Odd Steen; Institutionen för informatik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informatics; judgement ability; IT quality assessment; IT artefact; IT quality; knowledge in practice; systems theory; Informatik; systemteori;

    Sammanfattning : This work is about IT quality and systems developers' knowledge and view of it. IT quality is considered as the characteristics of a system or program that influence e.g. LÄS MER
