1. 1. Gendered experiences of work environment : A study of stress and ambiguity among dental students in Sweden

   Författare :Ingrid Schéle; Leif Hedman; Anne Hammarström; Eva Bejerot; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dental students; Swedish dental education; work and organisational theories; gender power relations; ambiguity; perceived stress; satisfaction; grounded theory; content analysis; SEM; cluster analysis; tandläkarstudenter; svensk tandläkarutbildning; arbets- och organisations teorier; genus och makt relationer; ambiguitet; upplevd stress; nöjdhet; grundad teori; innehållsanalys; SEM; kluster analys; Applied psychology; Tillämpad psykologi; Psychology; psykologi;

   Sammanfattning : This thesis explores how dental students experience their education. We aim to generate ways to understand which elements relate to the students’ experience based on current theories and models regarding the quality of working life and gender (and) power relations. LÄS MER

3. 2. Beware of Non-Supportive Leaders : Moderating Effects of Supportive Leadership on the Risks and Effects of Workplace Bullying

   Författare :Stefan Blomberg; Michael Rosander; Bengt Ståhlbom; Duncan Lewis; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Workplace bullying; Supportive leadership; Health; Role ambiguity; Hostile work climate; Moderation; Longitudinal; Arbetsplatsmobbning; Stödjande ledarskap; Hälsa; Otydliga roller; Fientligt arbetsklimat; Moderation; Longitudinell;

   Sammanfattning : The aim was to investigate how supportive leadership affects workplace bullying—both in terms of risk factors that may lead to bullying but also in terms of the effects of bullying. The thesis includes three survey studies based on different Swedish cohorts and using different research design in terms of the number of data collection waves and timeframes. LÄS MER

4. 3. Essays on Field Experiments and Impact Evaluation

   Författare :Remidius Denis Ruhinduka; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; adaptation to climate change; ambiguity; artefactual field experiment; behavioraleconomics; charcoal; credit; deforestation; endogenous switching regression; field experiment; guilt; honesty; impact evaluation; kindness; liquidity constraint; LPG stoves; rice marketing; risk preferences; system of rice intensification; Tanzania; time preferences;

   Sammanfattning : Paper 1: Improving Welfare Through Climate-Friendly Agriculture: The Case of the System of Rice Intensification We use rich survey data to investigate the economic impact of a climate-friendly rice farming method known as the system of rice intensification (SRI) on the welfare of rain-dependent small-holder farmers in Tanzania. SRI reduces water consumption by half, which makes it a promising farming system in the adaptation to climate change in moisture constrained areas, and it does not require flooding of rice fields, resulting in reduced methane emissions.

5. 4. Role of charge and spin fluctuations and their interplay in solids : A Green’s function approach

   Författare :Tor Sjöstrand; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Green’s function; correlations; collective excitations; screened interaction; electric polarization; orbital and spin magnetization; magnon-phonon interaction; Fierz ambiguity; time-dependent exchange-correlation potential;

   Sammanfattning : Due to the large number of electrons, solid state physics boils down to many-body approximations in which only selected types of collective excitations are taken into account, guided by the emergent properties of the material under study. In this thesis, the collective excitations of primary interest are electronic charge and spin fluctuations(plasmons and magnons) and nuclear charge fluctuations (phonons). LÄS MER

7. 5. Effects of management by objectives : studies of Swedish upper secondary schools and the Influence of role stress and self-efficacy on school leaders

   Författare :Erik Lindberg; Kerstin Nilsson; Elisabet Ljunggren; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Management by objectives; Goal commitment; performance; role stress; self-efficacy; Business studies; Företagsekonomi; företagsekonomi; Business Studies;

   Sammanfattning : The purpose of this dissertation is to explore the impacts of Management by Objectives (MBO) on upper secondary school education in Sweden. In particular the goal is to increase our understanding of how the implementation of MBO affects the schools and the role of head teachers. LÄS MER
