  1. 1. Den ojämlika dödligheten : Hjärtdödlighet och samhällsutveckling i två städer

    Författare :Björn Grip; Hans Nilsson; Roger Qvarsell; Göran Therborn; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inequality; coronary heart disease mortality; Linköping; Norrköping; city neighborhoods; change; social development; socio-economic factors; life-style; Ojämlikhet; hjärtkärldödlighet; Linköping; Norrköping; stadsdelar; förändringar; samhällsutveckling; socio-ekonomi; levnadssätt;

    Sammanfattning : Den ojämlika dödligheten är en studie av främst hjärt–kärldödlighet avseende perioden 1950–2010 i tvillingstäderna Linköping och Norrköping och konsekvenserna av ojämlikhet. Skillnaderna mellan städerna i dödlighet är stora. Under 1970-talet, då jämlikheten stod i focus, minskade dessa. LÄS MER

  3. 2. Optimal adaptive designs and adaptive randomization techniques for clinical trials

    Författare :Yevgen Ryeznik; Warwick Tucker; Andrew Hooker; Franz König; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optimal designs; optimal adaptive designs; randomization in clinical trials; restricted randomization; adaptive randomization; unequal cost; allocation ratio preserving randomization procedures; heterogeneous costs; multi-arm clinical trials; randomization-based inference; unequal allocation; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Sammanfattning : In this Ph.D. thesis, we investigate how to optimize the design of clinical trials by constructing optimal adaptive designs, and how to implement the design by adaptive randomization. LÄS MER

  4. 3. Social Ecography : International trade, network analysis, and an Emmanuelian conceptualization of ecological unequal exchange

    Författare :Carl Nordlund; Humanekologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ecological unequal exchange; commodity trade; ecological economics; world-system analysis; network analysis; human ecology; ecography;

    Sammanfattning : This thesis demonstrates how network analysis, ecological economics and the world-system perspective can be combined into an ecographic framework that can yield new insights into the underlying structure of the world-economy as well as its surrounding world-ecology. In particular, the thesis focuses on the structural theory of ecological unequal exchange, a theory suggesting a relationship between positionality within the world-system and unequal exchange of biophysical resources.

  5. 4. Unequal Valuations of Lives and What to Do About It : The Role of Identifiability, Numbers, and Age in Charitable Giving

    Författare :Hajdi Moche; Daniel Västfjäll; Arvid Erlandsson; Erkin Asutay; Annika Wallin; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Charitable giving; Donation decision; Identifiable victim effect; Singularity effect; Age effect; Compassion fade; Scope-insensitivity; Intervention; Deliberation; Unit asking method; Välgörenhetsgivande; Donationsbeslut; Identifierbarhetseffekt; Singularitetseffekt; Ålderseffekt; Intervention;

    Sammanfattning : Many people choose to donate money to help victims of humanitarian crises. However, people’s donation decisions often fail to reflect that all victims are equally valuable to help. Instead, some victims seem to be favored. LÄS MER

  7. 5. Optimal Subsampling Designs Under Measurement Constraints

    Författare :Henrik Imberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; inverse probability weighting; unequal probability sampling; optimal design; active sampling; M-estimation;

    Sammanfattning : We consider the problem of optimal subsample selection in an experiment setting where observing, or utilising, the full dataset for statistical analysis is practically unfeasible. This may be due to, e.g., computational, economic, or even ethical cost-constraints. LÄS MER
