2. 1. Covariate selection and propensity score specification in causal inference

   Author : Ingeborg Waernbaum; Xavier de Luna; Elena Stanghellini; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Covariate selection; graphical models; matching; observational studies; treatment effects; unconfoundedness; Statistics; Statistik;

   Abstract : This thesis makes contributions to the statistical research field of causal inference in observational studies. The results obtained are directly applicable in many scientific fields where effects of treatments are investigated and yet controlled experiments are difficult or impossible to implement. READ MORE

5. 3. Fighting for Aid : Foreign Funding and Civil Conflict Intensity

   Author : Daniel Strandow; Magnus Öberg; Michael G. Findley; Kristian Skrede Gleditsch; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aid; foreign aid; foreign assistance; relief; humanitarian; conflict; civil war; civil conflict; geographic concentration; intra-state; violence; military; contest; low-intensity; guerrilla; irregular; conventional; decision theory; contest success function; geo-coding; geo-referencing; territorial control; propensity score; Africa; South of the Sahara; Peace and Conflict Research; Freds- och konfliktforskning;

   Abstract : This dissertation focuses on the sub-national impact of foreign aid on civil conflicts by asking the question: How does foreign aid committed to contested areas affect the intensity of violence in those areas? The main theoretical contribution is to focus on how aid influences warring parties’ decisions to engage in contests over territorial control and how that in turn influences violence intensity. The study introduces two concepts: funding concentration and barriers to exploiting aid. READ MORE

6. 4. Real-Time Monitoring of Healthcare Interventions in Routine Care : Effectiveness and Safety of Newly Introduced Medicines

   Author : Thomas Cars; Johan Sundström; Björn Wettermark; Martin Neovius; Til Stürmer; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electronic Health Records; Comparative Effectiveness Research; Comparative Safety Research; Sequential drug monitoring; propensity score; real-world data; infliximab; TNF-inhibitors; dronedarone; amiodarone; flecainide; Farmakoepidemiologi; Pharmacoepidemiology;

   Abstract : Before market authorization of new medicines, their efficacy and safety are evaluated using randomized controlled trials. While there is no doubt about the scientific value of randomized trials, they are usually conducted in selected populations with questionable generalizability to routine care. READ MORE
