  2. 1. Employee selection : Mechanisms behind practitioners’ preference for hiring practices

    Author : Kristina Langhammer; Claudia Bernhard-Oettel; Johnny Hellgren; Scott Highhouse; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; 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

  4. 2. Selection in sperm and its consequences : Exploring haploid selection, ageing and epigenetic effects in sperm

    Author : Cosima Hermans Née Hotzy; Simone Immler; Göran Arnqvist; Mariana Wolfner; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; sperm; evolution; selection; haploid selection; epigenetics; sperm-mediated effects; trans-generational effects; sperm ageing; sperm senescence;

    Abstract : Sexually reproducing eukaryotes are typically going through a biphasic life cycle with a diploid and a haploid phase. Unlike in plants where selection on haploid pollen genotypes is well established, the possibility of selection occurring in animal sperm is currently not known. READ MORE

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

    Author : Samuel Kiboi; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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. Haploid selection in animals : Exploring the fitness consequences and underlying mechanisms

    Author : Ghazal Alavioon; Simone Immler; Tommaso Pizzari; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; sperm; evolution; haploid selection; reproductive aging; fitness;

    Abstract : A consequence of sexual reproduction in eukaryotes is the evolution of a biphasic life cycle with alternating diploid and haploid gametic phases. While our focus in evolutionary biology is on selection during the diploid phase, we know relatively little about selection occurring during the haploid gametic stage. READ MORE

  7. 5. Philosophical controversies in the evaluation of medical treatments : With a focus on the evidential roles of randomization and mechanisms in Evidence-Based Medicine

    Author : Alexander Mebius; John Cantwell; Jeremy Howick; Sven Ove Hansson; Julian Reiss; KTH; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; HUMANITIES; HUMANIORA; MEDICIN OCH HÄLSOVETENSKAP; HUMANIORA; MEDICAL AND HEALTH SCIENCES; HUMANITIES; Evidence; randomized controlled trials; observational studies; systematic reviews; meta-analysis; methodology; process assessment; outcome assessment; medical care; randomization; evidence-based medicine; selection bias; philosophy of medicine; philosophy of science; mechanisms; quality of evidence; animal studies; treatment effect; causation by absence; medical technology; Filosofi; Philosophy;

    Abstract : This thesis examines philosophical controversies surrounding the evaluation of medical treatments, with a focus on the evidential roles of randomised trials and mechanisms in Evidence-Based Medicine. Current 'best practice' usually involves excluding non-randomised trial evidence from systematic reviews in cases where randomised trials are available for inclusion in the reviews. READ MORE
