  3. 2. Multivariate Aspects of Phylogenetic Comparative Methods

    Författare :Krzysztof Bartoszek; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General Linear Model; Ornstein-Uhlenbeck process; Multivariate phylogenetic comparative method; Evolutionary model; Adaptation; Optimality; Measurement error; Regression; Adaptation; Major-axis regression; Reduced major-axis regression; Structural equation; Allometry; Phylogenetic inertia; Allometry;

    Sammanfattning : his thesis concerns multivariate phylogenetic comparative methods. We investigate two aspects of them. The first is the bias caused by measurement error in regression studies of comparative data. We calculate the formula for the bias and show how to correct for it. LÄS MER

  4. 3. On the Origins of mobile Antibiotic Resistance Genes : A comparative genomics approach

    Författare :Stefan Ebmeyer; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibiotic resistance; comparative genomics; bacterial genomics; antibiotic resistance genes;

    Sammanfattning : Mobile antibiotic resistance genes (ARGs), transferable between bacterial cells, are major contributors to the antibiotic resistance crisis we are facing today. From which organisms pathogens acquired these genes is mostly unknown, yet knowledge about their origin is needed in order to limit the emergence and spread of novel ARGs in the future. LÄS MER

  5. 4. Gall induction in gall wasps (Cynipidae s. lat.) : Insights from comparative genomics

    Författare :Erik Gobbo; Fredrik Ronquist; Scott Egan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gall induction; comparative genomics; evolution; selection analysis; microbiome; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Cynipidae are a family of wasps (Hymenoptera), whose larval stages develop inside plant galls, that is, abnormal plant structures formed in response to the presence of foreign organisms. Most cynipids are gall inducers and are often capable of notable levels of host manipulation. LÄS MER

  7. 5. Hospitalizations for Ambulatory Care-Sensitive Conditions in Brazil and Portugal : A Comparative Study

    Författare :João Victor Muniz Rocha; Rui Manuel Candeias Santana; Sam Willner; Maria Isabel Guedes Loureiro; Fúlvio Borges Nedel; José Alberto da Silva Freitas; Julian Alejandro Perelman; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ambulatory care sensitive conditions; primary health care; quality of health care; inter-country comparison;

    Sammanfattning : Background: Ambulatory Care Sensitive Conditions (ACSC) are health conditions for which adequate management, treatment and interventions delivered in outpatient setting could avoid the need of hospital admission. Hospitalizations for ACSC have been used to assess access, quality, and performance of the Primary Health Care (PHC). LÄS MER
