   Sammanfattning : Background: During the last decades evidence has been accumulating that psychosocial factors including social isolation, depressive symptoms and work stress increase risk for CHD incidence and prognosis. Although depression has been shown to be around twice as common in women as in men and women with CHD have a poorer prognosis than men in terms of both physical health and psychosocial recovery, most studies of psychosocial risk factors and CHD, have been performed in predominantly male populations.

3. 7. Risk factors for injury in men´s professional football

   Författare :Karolina Kristenson; Martin Hägglund; Jan Ekstrand; Markus Waldén; Harald Roos; Linköpings universitet; []
   Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Age; artificial turf; cohort study; elite; epidemiology; overuse injury; soccer; surface; sporting injuries; playing position;

   Sammanfattning : This thesis includes four papers based on three different prospective cohort studies on injury characteristics in men’s professional football. The same general methodology was used in all papers. Time-loss injuries and player individual exposure was registered for match and training separately. LÄS MER

4. 8. On efficient use of censored data and covariate factors in survival analysis and maintenance scheduling

   Författare :Ulf Westberg; Luleå tekniska universitet; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

   Sammanfattning : This thesis deals with survival analysis and maintenance scheduling, two important issues to achieve efficient use of different production systems. In survival analysis of failure time data, the survival function and the cumulative hazard function are important reliability characteristics. LÄS MER

5. 9. Dispersion modelling of volcanic emissions

   Författare :Adam Dingwell; Rutgersson Anna; David Simpson; Uppsala universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; dispersion modelling; atmospheric; volcano; gas emissions; volcanic ash; FLEXPART; FLEXPART-WRF; Spridningsmodellering; atmosfär; vulkan; gasutsläpp; vulkanaska; FLEXPART; FLEXPART-WRF; Meteorology; Meteorologi;

   Sammanfattning : Gases and particles released by volcanoes pose a serious hazard to humans and society. Emissions can be transported over long distances before being reduced to harmless concentrations. Knowing which areas are, or will be, exposed to volcanic emissions is an important part inreducing the impact on human health and society. LÄS MER

7. 10. Job Loss: Consequences and Labor Market Policy

   Författare :Jonas Cederlöf; Peter Fredriksson; David Seim; Alexandre Mas; Uppsala universitet; []
   Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

   Sammanfattning : Essay I: This paper takes a novel approach to estimating the effects of involuntary job loss on future earnings, wages and employment. Whereas the previous literature has relied on mass layoffs and plant closures for exogenous variation in displacement, I use the fact that who is laid off is often determined by a seniority rule, specifically the last-in-first-out (LIFO) rule.
