1. 1. Corruption, Distortions and Development

   Författare :Sebastian Jävervall; Niklas Bengtsson; Eva Mörk; Jakob Svensson; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accountability; Corruption; Economic Development; Information Disclosure; International Trade; Meritocracy; Political Distortions; Social Unrest; State Capacity; Economics; Nationalekonomi;

   Sammanfattning : Essay I: Does increased government transparency make bureaucracies more meritocratic? I study the impact of politician disclosure requirements on the assignment of bureaucrats to public posts. I collect detailed information on bureaucrats' qualifications and construct a novel measure of bureaucratic mismatch—an index measuring the extent to which a bureaucrat is under- or overqualified to perform a specific task.

4. 3. Hardening Distortions of Serial Produced Gears

   Författare :Anders Olofsson; Stefan Jonsson; Julia Gerth; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hardening distortions; crown wheel; main shaft gear; gear runout; back-face tilt; macrosegregation; ingot casting; continuous casting; case hardening; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : Hardening distortions are unwanted changes in shape and dimension that arise during hardening of steel components. Uncontrolled distortions induce random errors to the manufacturing process, and have a strong negative impact on manufacturing costs. LÄS MER

5. 4. Memory Distortions Induced by Fluency : Behavioural and Electrophysiological Investigations

   Författare :Anne-Cécile Treese; Institutionen för psykologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; memory distortions; recall-to-reject; celebrity; fluency; emotion; attractiveness; memory control;

   Sammanfattning : The investigation of memory distortions provides insights into how memory normally works. Adopting a cognitive neuroscience perspective, the present thesis aimed at investigating memory distortions and the neural correlates of processes contributing to successful control of memory interference in healthy participants.

7. 5. Geometric distortions in MRI based radiotherapy and PET/MRI

   Författare :Josef Lundman; Tufve Nyholm; Anne Larsson; Jörgen Olofsson; Marco Riboldi; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; MRI; PET MR; PET MRI; medical imaging; radiotherapy; geometrical distortions; MR-only; MRI-only; radiofysik; radiation physics;

   Sammanfattning : Magnetic resonance imaging (MRI) offers high soft-tissue contrast compared to computed tomography (CT). This contrast is helpful in many cases, not least for delineating tumours for radiotherapy treatment, and has led to increasing use in radiotherapy treatment planning (RTP). LÄS MER
