  1. 1. Essays on Estimation Methods for Factor Models and Structural Equation Models

    Author : Shaobo Jin; Fan Yang-Wallentin; Rolf Larsson; Li Cai; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; shrinkage; factor rotation; penalized maximum likelihood; pseudo-maximum likelihood; multi-group analysis; ordinal data; robustness; Statistics; Statistik;

    Abstract : This thesis which consists of four papers is concerned with estimation methods in factor analysis and structural equation models. New estimation methods are proposed and investigated.In paper I an approximation of the penalized maximum likelihood (ML) is introduced to fit an exploratory factor analysis model. READ MORE

  2. 2. Some Aspects on Confirmatory Factor Analysis of Ordinal Variables and Generating Non-normal Data

    Author : Hao Luo; Fan Yang-Wallentin; Johan Lyhagen; Karl Jöreskog; Marie Wiberg; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; confirmatory factor analysis; ordinal variables; maximum likelihood; weighted least squares; polychoric correlation; non-normal data; Fleishman s method; Monte Carlo simulation; Statistics; Statistik; Statistics; Statistik;

    Abstract : This thesis, which consists of five papers, is concerned with various aspects of confirmatory factor analysis (CFA) of ordinal variables and the generation of non-normal data. The first paper studies the performances of different estimation methods used in CFA when ordinal data are encountered. READ MORE

  3. 3. Power Reactor Noise Studies and Applications

    Author : Vasiliy Arzhanov; Chalmers University of Technology; []
    Keywords : power spectra; control rod vibrations; Green s function; nesting hypothesis; adjoint function; fluctuating boundary; noise diagnostics; Accelerator Driven System; localisation algorithm; point reactor and adiabatic approximation;

    Abstract : The present thesis deals with the neutron noise arising in power reactor systems. Generally, it can be divided into two major parts: first, neutron noise diagnostics, or more specifically, novel methods and algorithms to monitor nuclear industrial reactors; and second, contributions to neutron noise theory as applied to power reactor systems.

  4. 4. From market orientation to orientation towards international marjets (OIM) of born global firms : evaluating the impact of OIM on born global firms' performance

    Author : Rosalina Torres-Ortega; Spain Autonomous University of Barcelona; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Born global firms; market orientation; orientation towards international markets; performance; scale validation; multi-country approach; structural equation model; Företagsekonomi; Business administration;

    Abstract : Although there is a considerable amount of research on market orientation, research on this concept in the context of born global firms is still lacking a precise definition and full operationalization. This research aims to investigate how the market orientation (MO) concept could be understood for a specific type of firm: the born global firm. READ MORE

  5. 5. Values and welfare state attitudes : The interplay between human values, attitudes and redistributive institutions across national contexts

    Author : Joakim Kulin; Mikael Hjerm; Stefan Svallfors; Michael Shalev; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Basic human values; attitudes; welfare state; institutions; Europe; Sociology; sociologi;

    Abstract : While there is much research aiming to assess the determinants of welfare state attitudes, there are not many studies focussing on how human values influence attitude formation. This thesis explores the relationship between values and welfare state attitudes across national contexts. READ MORE
