1. 26. Self-Normalized Sums and Directional Conclusions

   Författare :Fredrik Jonsson; Allan Gut; Josef Steinebach; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Self-normalized sums; heavy-tailedness; Student s t-statistic; distributional symmetry; exponential tilting; directional conclusions; reversal rates; multiple statistical inference; the Benjamini-Hochberg procedure;

   Sammanfattning : This thesis consists of a summary and five papers, dealing with self-normalized sums of independent, identically distributed random variables, and three-decision procedures for directional conclusions. In Paper I, we investigate a general set-up for Student's t-statistic. LÄS MER

3. 27. Essays on Societal Cost of Alcohol and Related Issues - A Health Economic Analysis

   Författare :Johan Jarl; Socialepidemiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wages; Productivity loss; Societal cost; COI; Consumption groups; Alcohol consumption; Drinking history; Health; Sickness absence; Sweden.;

   Sammanfattning : The consumption of alcoholic beverages has wide effects, for example, causes premature mortality, prevents certain heart diseases, increases crime rates, and affects quality of life. The main problems with alcohol consumption from an economic point of view are lack of information for consumers when making consumption decisions, externalities, and the addictive nature. LÄS MER

4. 28. Study of heat release rates of mining vehicles in underground hard rock mines

   Författare :Rickard Hansen; Haukur Ingason; Nicholas Dembsey; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : A unique study on fire safety in hard rock underground mines with focus on heat release rates of mining vehicles is presented. A literature inventory was conducted with respect to fires in underground hard rock mines, which revealed that the most common fire cause in underground mines was flammable liquid sprayed onto hot surface and the most common fire object was a vehicle.

5. 29. Flexible parametric models for cancer patient survival : loss in expectation of life and further developments

   Författare :Hannah Bower; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Population-based cancer studies can contribute to a better understanding of cancer patient survival. The general aim of this thesis was to develop and apply statistical methods for population-based cancer studies to ensure understanding in this area. In any analysis setting, it is important that the statistical methods are appropriate. LÄS MER

7. 30. Ecosystem functioning in streams : Disentangling the roles of biodiversity, stoichiometry, and anthropogenic drivers

   Författare :André Frainer; Roland Jansson; Brendan McKie; Jonathan Benstead; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; detrital food web; functional diversity; stoichiometry; nitrogen and phosphorus concentrations; recalcitrant carbon; spatial and temporal species distribution; pools and riffles; isotopes; leaf decomposition rates; land use; restoration; habitat complexity;

   Sammanfattning : What will happen to ecosystems if species continue to go extinct at the high rates seen today? Although ecosystems are often threatened by a myriad of physical or chemical stressors, recent evidence has suggested that the loss of species may have impacts on the functions and services of ecosystems that equal or exceed other major environmental disturbances. The underlying causes that link species diversity to ecosystem functioning include species niche complementarity, facilitative interactions, or selection effects, which cause process rates to be enhanced in more diverse communities.
