1. 1. Development of the Stress Strategy Test as a personnel selection instrument

   Författare :Rolf Federmann; Institutionen för psykologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; military personnel selection.; stress; cognition; personality; personnel selection; Serial Colour Word Test; Stroop effect; Stroop test; Stress Strategy Test;

   Sammanfattning : The thesis concerns the development of a computerised test, termed the Stress Strategy Test (SST), intended for use in a personnel selection and placement context. A similar but less extended form of that test, termed the Stroop Strategy Test, developed first, was adjudged to be somewhat less effective as a selection instrument. LÄS MER

5. 4. A multivariate approach to QSAR

   Författare :Sven Hellberg; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QSAR; beta-adrenergic agents; haloalkanes; halogenated anesthetics; peptides; fractional factorial design; multivariate data analysis; principal components PC ; partial least squares PLS ;

   Sammanfattning : Quantitative structure-activity relationships (OSAR) constitute empirical analogy models connecting chemical structure and biological activity. The analogy approach to QSAR assume that the factors important in the biological system also are contained in chemical model systems.The development of a QSAR can be divided into subproblems:1.

7. 5. Statistical aspects of modeling panel data originating from smallholder household surveys in Sub-Saharan Africa and Vietnam

   Författare :Sultana Nasrin; Statistiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; power of test; endogeneity; multivariate; longitudinal data; diversification;

   Sammanfattning : This thesis focuses on multivariate multilevel modeling of panel data originated from smallholder farm surveys in Sub-Saharan African (SSA) countries and Vietnam to investigate driving forces in maize and rice production in SSA and diversification of farms in the rice sector in Vietnam. We also present and evaluate different tests for endogeneity in explanatory binary variables in multivariate linear regression models. LÄS MER
