  1. 6. Detecting Signatures of Selection within the Dog Genome

    Författare :Abhirami Ratnakumar; Matthew Webster; Kerstin Lindblad-Toh; Greg Barsh; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dog; evolution; domestication; PRDM9; recombination; positive selection; selective sweep;

    Sammanfattning : Deciphering the genetic basis of phenotypic diversity is one of the central aims of biological research. Domestic animals provide a unique opportunity for making substantial progress towards this goal. LÄS MER

  3. 7. Context-Aware Optimized Service Selection with Focus on Consumer Preferences

    Författare :Jens Kirchner; Welf Löwe; Mats Neovius; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SOC; Service Selection; Service Recommendation; Information Supply Chains; Machine Learning; Computer Science; Datavetenskap;

    Sammanfattning : Cloud computing, mobile computing, Service-Oriented Computing (SOC), and Software as a Service (SaaS) indicate that the Internet emerges to an anonymous service market where service functionality can be dynamically and ubiquitously consumed. Among functionally similar services, service consumers are interested in the consumption of the services which perform best towards their optimization preferences. LÄS MER

  4. 8. Costs of foraging in a dry tropical environment

    Författare :Mary Molokwu; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; foraging behavior; seasonality; predation risk; granivorous birds; food availability; water; temperature; savannah; dry tropics; energy; secondary compounds; diet selection;

    Sammanfattning : This study evaluates the costs associated with foraging for birds in a savannah woodland area in central Nigeria. Specifically, it looks at the following questions: 1) how does seasonal variability in food and water availability affect the value of resources to birds in dry environments? 2) Does proximity to water affect foraging decisions? What implication will this have in the management of savannah birds? 3) Are tropical birds mostly affected by metabolic or predation costs? 4) What factors affect diet selection in birds and how? 5) How are birds adapted to hot dry environments? I carried out experiments in the field and in an aviary and provided artificial food patches, consisting of feeding trays with seeds mixed in sand or pebbles (in the aviary study). LÄS MER

  5. 9. Equality of opportunity, heterogeneity and poverty

    Författare :William Nilsson; Karl-Gustaf Löfgren; Tomas Sjögren; Anders Björklund; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Equality of opportunity; Semiparametric; Poverty; Heterogeneity; State dependence; Twins; Unemployment; Divorce; Spousal response; Selection; Panel data; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : Paper [I] studies equality of opportunity in Sweden. The distinction between circumstances that constrain an individual’s opportunities and the individual choices also affecting a particular outcome is the main idea of theories of equality of opportunity. LÄS MER

  7. 10. 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 :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.
