1. 16. Community Robustness Analysis : Theoretical Approaches to Identifying Keystone Structures in Ecological Communities

   Författare :Sofia Berg; Tomas Jonsson; Bo Ebenman; Daniel Stouffer; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Most of the world’s ecosystems suffer from stress caused by human activities such as habitat destruction, fragmentation, overexploitation of species and climate change. These factors affect the reproduction and/or survival of individual species as well as interactions between species in ecological communities. LÄS MER

3. 17. Innovation and Productivity : A Microdata Analysis

   Författare :Pardis Nabavi; Hans Lööf; Jacques Mairesse; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

   Sammanfattning : This doctoral thesis consists of four papers. The first two papers deal with firms’ innovation strategies, knowledge spillover and their impact on growth and productivity. The last two papers are focused on spinoffs and their survival. LÄS MER

4. 18. Centralized Ovarian Cancer Care - Complications, Costs and Survival

   Författare :Charlotte Palmqvist; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovarian cancer; Survival; Centralization; Surgery; Cytoreduction; Residual disease; Postoperative complications; Cost of illness; Direct costs; Indirect cost; Epidemiology;

   Sammanfattning : Background: Ovarian cancer is often diagnosed at advanced stages, and its mortality is high. Surgical treatment of advanced ovarian cancer strives toward complex primary debulking surgery (PDS), aiming for complete cytoreduction (R0) and improved survival. LÄS MER

5. 19. Stress susceptibility, beta-blocker use and cancer survival

   Författare :Ruzan Udumyan; Katja Fall; Scott Montgomery; Fang Fang; Edoardo Botteri; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stress resilience; β-blockers; primary cancer; survival analysis; overall mortality; cancer-specific mortality; register-based cohort study;

   Sammanfattning : Accumulating evidence suggests that chronic stress may influence tumour biology through activation of neuroendocrine pathways and thus impair survival. However, measuring stressful exposures and their influence on health is challenging, partly due to substantial inter-individual variation in stress susceptibility. LÄS MER
