Competitive gaming, or the growing sport like scene around computer games, has not been studied much in the academic field of Games Studies. Drawing on ethnographic and interview work both inside and outside the game this thesis examines player-produced culture around raids in the Massive Multiplayer Online Game World of Warcraft. Competitive elements in WoW, such as races to be the “World First”

Idre Fjälls snow production has been analyzed in cooperation with Snowtech AB. A survey of the energy use and how to decrease the energy use was carried out. The first part is about snow and snowmaking. Natural snow consists of water molecules that form a hexagonal pattern in solid state. The reason to the hexagonal pattern is due to dendritic growth during the snow crystals journey through the cl

Osteosynthesis (OS) and hemiarthroplasty (RA) are the commonest treatments for displaced cervical hip fractures in the elderly, but there is no consensus as to which is better. In this prospective matched-pair study we compared these methods as regards functional outcome. In 1989-1996, using the same standardized forms, all displaced cervical hip fractures were prospectively registered in the univ

Stated preference (SP) surveys attempt to obtain monetary values for non-market goods that reflect individuals’ “true” preferences. Numerous empirical studies suggest that monetary values from SP studies are sensitive to survey design and so may not reflect respondents’ true preferences. This study examines the effect of time framing on respondents’ willingness to pay (WTP) for car safety. We expl

Alzheimer's disease (AD) is characterized by protein aggregates, i.e. senile plaques and neurofibrillary tangles. The ubiquitin-proteasome system has been proposed a role in proteolytic removal of these protein aggregates. Ubiquitin carboxy-terminal hydrolase L1 (UCHL1) is a de-ubiquitinating enzyme with important functions in recycling of ubiquitin. The S18Y polymorphism of the UCHL1 gene confers

Provocation is an integral part of Socrates’ philosophical method. Does provocation have a similar methodological function in art? My tentative answer is no. In the Socratic method, provocation is used both on an individual level to force a person to think better (preferably in ethical matters) and on a general level in order to keep a society awake. A society should never rest but “be stirred int

The question of how diverging populations become separate species by restraining gene flow is a central issue in evolutionary biology. Assortative mating might emerge early during adaptive divergence, but the role of other types of reproductive barriers such as migration modification have recently received increased attention. We demonstrate that two recently diverged ecotypes of a freshwater isop

Recent genome-wide association studies have described many loci implicated in type 2 diabetes (T2D) pathophysiology and beta-cell dysfunction but have contributed little to the understanding of the genetic basis of insulin resistance. We hypothesized that genes implicated in insulin resistance pathways might be uncovered by accounting for differences in body mass index (BMI) and potential interact

Many studies have been made on the impact of supplemental instruction in supported courses, most show significantly better examination results for students attending supplemental instruction in comparison to those who do not. However, remarkably little attention has been devoted to following up whether the benefits of supplemental instruction reach beyond the course it supports. The present study
