  1. 1. Essays on Determinants of Individual Performance and Labor Market Outcomes

    Author : Olof Rosenqvist; Oskar Nordström Skans; Lena Hensvik; Ghazala Azmat; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Confidence; success; failure; performance; regression discontinuity design; golf; gender differences; glass ceiling; voting age; political knowledge; civic interest; dynamic effects; sickness absence; production disruption; coworker substitutes; hiring decisions; separations; Economics; Nationalekonomi;

    Abstract : Essay 1 (with Oskar Nordström Skans): This paper provides field evidence on the causal impact of past successes on future performances. Since persistence in success or failure is likely to be linked through, potentially time-varying, ability it is intrinsically difficult to identify the causal effect of succeeding on the probability of performing well in the future.

  2. 2. New Techniques for Chiral Separations

    Author : Jeanette Olsson; Lars Blomberg; Steen Honoré Hansen; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; analytical chemistry; chiral separation; GC; CE; CEC; Analytical chemistry; Analytisk kemi; Kemi; Chemistry;

    Abstract : Gas chromatography (GC) has been utilized for the study of enantiomer resolution of the atropisomers of PCBs, o,p´-DDD and o,p´-DDT. Different substituents and concentrations of cyclodextrin, capillary dimensions and type of stationary phase films have been investigated to achieve the resolution of as many of the atropisomers on one column as possible.

  3. 3. Novel detection schemes and high resolution separations in microcolumn liquid separations

    Author : James N. Alexander; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Three micro detectors were developed and studied using micro-liquidchromatography (micro-LC). An evaporative light scattering detector (ELSD) nebulizer was developed for use with flow rates ranging from 0.5 to 10 µL/min. READ MORE

  4. 4. Enantiomeric Separations using Chiral Counter-Ions

    Author : Jakob Haglöf; Curt Pettersson; Anders Karlsson; Jacques Crommen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Capillary Electrophoresis; Chiral Counter-Ion; Divalent Dipeptide; Enantioselectivity; Electroosmosis; Chemometrics; Molecular Descriptor; Structure-Enantioselectivity Relationship; Pharmaceutical chemistry; Farmaceutisk kemi; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Abstract : This thesis describes the use of chiral counter-ions for the enantiomeric separation of amines in non-aqueous capillary electrophoresis. The investigations have been concentrated on studies of the influence, of the chiral counter-ion, the solvent, the electrolyte and the analyte, on the enantioselective separation. READ MORE

  5. 5. Separations in Multivocality: Reconfiguring Dialogue through Design

    Author : Jonathan Geib; Chalmers tekniska högskola; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; dialogue; architecture; participation; multivocality; post-political; indirect dialogue; separation; public space; artistic research; design;

    Abstract : This thesis takes an artistic research approach concerned with the designer's agency within processes of public space.  It traverses contexts of urbanism, urban design, architecture, art, design and participatory processes but also draws from other fields. READ MORE
