    Author : Yevgen Ryeznik; Warwick Tucker; Andrew Hooker; Franz König; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Distributive Preferences in Social Dilemmas

    Author : Ali Kazemi; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social dilemma; public good dilemma; cooperation; group goal; distributive fairness; self-interest; allocation preference;

    Abstract : In research on social dilemmas and in game theoretic research, it was for a long time assumed that the rational decision is to choose an option with the most beneficial economic outcome to oneself. Yet, in group situations, individuals’ decisions have been shown to be influenced by non-economic motives. READ MORE

  5. 3. Interpretation of diagnostic information given patient characteristics

    Author : Martin Gellerstedt; Hans Åhlfeldt; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; reference values; diagnostic theory; diagnostic tests; partitioning; prevalence function; reference values; diagnostic theory; diagnostic tests; partitioning; prevalence function;

    Abstract :  The aim with this thesis was to describe, exemplify and develop theory for reference values and diagnostic tests, especially focusing on the variability between individuals. To facilitate interpretation of medical information it is common to establish some kind of limit. There are several different rationales for the choice of such a limit. READ MORE

  6. 4. Analysis and Design of Spatially-Coupled Codes with Application to Fiber-Optical Communications

    Author : Christian Häger; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bit mapper; generalized product codes; generalized low-density parity-check codes; bounded-distance decoding; density evolution; spatial coupling; staircase codes.; braided codes; Bit-interleaved coded modulation;

    Abstract : The theme of this thesis is the analysis and design of error-correcting codes that are suitable for high-speed fiber-optical communication systems. In particular, we consider two code classes. The codes in the first class are protograph-based low-density parity-check (LDPC) codes which are decoded using iterative soft-decision decoding.

  7. 5. Essays on Macroeconomics, Monetary Policy and Mobility

    Author : John Vincent Kramer; Kurt Mitman; Per Krusell; Kuhn Moritz; Stockholms universitet; []

    Abstract : The Cyclicality of Earnings Growth Along the Distribution - Causes and ConsequencesEarnings growth is more procyclical at the bottom of the income distribution than at the top. Using high-quality administrative data from Germany, I show that the heterogeneity is chiefly driven by transitions between employment and non-employment, specifically job-finding. READ MORE
