  2. 1. Antibiotic Resistance : Selection in the Presence of Metals and Antimicrobials

    Author : Lisa M. Albrecht; Dan I Andersson; Alex O'Neill; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance; Metals; Antimicrobials; Bacterial evolution; Bacterial genetics; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : The external environment is complex: Antibiotics, metals and antimicrobials do not exist in isolation but in mixtures. Human activities such as animal husbandry, fertilization of agricultural fields and human medicine release high amounts these compounds into the environment. READ MORE

  4. 2. Antibiotic resistance gone wild : A One Health perspective on carriage, selection and transmission of Extended-Spectrum Cephalosporinase- and Carbapenemase-producing Enterobacteriaceae

    Author : Clara Atterby; Josef D. Järhult; Nicola Williams; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotic resistance; E. coli; K. pneumoniae; ESBL; AmpC; Carbapenemase; ciprofloxacin resistance; colistin resistance; rural; wildlife; birds; sub-MIC; MSC; Cambodia; environment; epidemiology; Infektionssjukdomar; Infectious Diseases;

    Abstract : Antibiotics have saved millions of lives since they came into clinical use during the Second World War in the 1940s. Today, our effective use of antibiotics is under great threat due to emerging antibiotic resistance in bacteria. This thesis addresses the problems of antibiotic resistance from a ”One Health” perspective. READ MORE

  5. 3. Male and female selective mechanisms, reproductive success and gene flow

    Author : Samuel Kiboi; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; Cucumis sativus.; genetic marker; gene flow; reproduction; embryo abortion; resistance; maternal selection; sexual selection; pollen competition; selection;

    Abstract : In this thesis, I have studied male and female selective mechanisms that can affect plant reproductive success and gene flow. I have focussed on sexually selected traits, mainly pollen competition and maternal sorting mechanisms, for example through non-random ovule abortion. READ MORE

  6. 4. Selection of Resistance at very low Antibiotic Concentrations

    Author : Erik Gullberg; Dan I Andersson; Diarmaid Hughes; Linus Sandegren; Laura Piddock; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotic resistance; Selection; Antibiotic resistant bacteria; Minimal inhibitory concentration; Heavy metals; Conjugative plasmid; ESBL; Mikrobiologi; Microbiology; Biology with specialization in Microbiology; Biologi med inriktning mot mikrobiologi; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : The extensive medical and agricultural use and misuse of antibiotics during the last 70 years has caused an enrichment of resistant pathogenic bacteria that now severely threatens our capacity to efficiently treat bacterial infections. While is has been known for a long time that high concentrations of antibiotics can select for resistant mutants, less is known about the lower limit at which antibiotics can be selective and enrich for resistant bacteria.

  7. 5. Employee selection : Mechanisms behind practitioners’ preference for hiring practices

    Author : Kristina Langhammer; Claudia Bernhard-Oettel; Johnny Hellgren; Scott Highhouse; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; employee selection decision making; employee data collection methods; hiring practices; self-efficacy; causal attribution; behavioral intention; agency; Psychology; psykologi;

    Abstract : Despite the great advances science has made in developing selection decision aids practitioners’ generally remain reluctant to adopt them. This phenomenon is considered today one of the greatest gaps in industrial, work and organizational psychology. READ MORE
