  2. 1. Raising Voices : Singing repertoire and practices in Swedish schools

    Author : David Johnson; Lärare (Musikhögskolan); []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Singing; Repertoire; Children; Schools; Survey; Ethnomusicology; Cantometrics; Microevolution;

    Abstract : This doctoral study aims to (i) investigate current song repertoire and singing practices in Swedish elementary school music education and (ii) to critically assess what factors may be seen to affect singing practices and repertoire choice. It looks to map out how much young students are singing in the general music classroom, what they sing, and how they sing, and to discuss possible implications for pedagogical practice from an ethnomusicological perspective.

  5. 3. Palaeogenomic reconstruction of woolly mammoth evolutionary history and extinction dynamics

    Author : Marianne Dehasque; Love Dalén; David Díez-del-Molino; Rike Stelkens; Rebecca N. Johnson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; woolly mammoth; Mammuthus primigenius; extinction; Wrangel Island; ancient DNA; palaeogenomics; radiocarbon dating; structural variants; genome erosion; population structure; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Biodiversity is declining globally. Yet, the biological and genetic processes associated with these declines on a longer timescale are still poorly understood. Ancient DNA is a powerful tool to study evolution in real-time. Despite advances in the field, there is further need for refinement of laboratory and computational techniques. READ MORE

  6. 4. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities

    Author : Daniela Guasconi; Gustaf Hugelius; Sara Cousins; Stefano Manzoni; Petra Fransson; David Johnson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soil; soil carbon; soil ecology; roots; root traits; microbial communities; grasslands; climate change; drought; land management; compost; naturgeografi; Physical Geography;

    Abstract : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. READ MORE

  7. 5. Non-linear dynamic modelling for panel data in the social sciences

    Author : Shyam Ranganathan; David JT Sumpter; Oliver Johnson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dynamical systems; stochastic models; Bayesian; panel data; social sciences; development; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Abstract : Non-linearities and dynamic interactions between state variables are characteristic of complex social systems and processes. In this thesis, we present a new methodology to model these non-linearities and interactions from the large panel datasets available for some of these systems. READ MORE
