Generations in motion : The transition in Hungary and the democratic change of regime, 1987-94

Popular AbstractDen här avhandlingen handlar om enpartistatens kollaps i Ungern och övergången till parlamentarisk demokrati i slutet av 1980- och början av 90-talet. Denna process, fortsättningsvis kallad transitionsprocessen, medförde förändringar inte bara i den politiska toppen, utan hade också återverkningar på de intellektuella och ekonomiska fälten. Drivkraften bakom dessa förändringar var,This dissertation explains the transition - the change of political system from a one-party state to a multi-party system - in Hungary as the result of a generation change, where different generations with different historical experiences either lost or gained political capital. It also includes a review of what consequences the changes in the political field had for the intellectual and economic

Long Term Stability of Time Preferences and the Role of the Macroeconomic Situation

We look at the stability of survey based subjective time preferences over time. Using data from a Dutch panel survey spanning the period 1998 to 2012, the stability of subjective time preferences at the aggregate level and at the individual level are studied. While aggregate preferences are clearly unstable, individual subjective time preferences are relatively stable over time. In order to shed l

I litteraturens mittfåra. Månadens bok och svensk bokmarknad under 1970-talet

Popular Abstract in Swedish Föreliggande avhandling, I litteraturens mittfåra, behandlar bokmarknad, bokklubbar och litteraturen under 1970-talet i Sverige. Bakgrunden till undersökningen är de radikala förändringar som skedde på den svensk bokmarknaden efter den genomgripande avregleringen av handeln med böcker 1970. Bokklubbarna växte från att inneha en marknadsandel på 9% 1970 till att ha 30% aThe present dissertation, I litteraturens mittfåra, deals with book trade, book clubs, and the fiction prose of the 1970s in Sweden. The background to the study is the radical change in Swedish book trade through a far-reaching deregulation of the trade in 1970. The book clubs expanded from a position where they held a 9% share of the market in 1970 to a market share of 30% in 1980.And the specifi

Production of Ethanol from Spruce at High Solids Concentrations - An Experimental Study on Process Development of Simultaneous Saccharification and Fermentation

Popular Abstract in Swedish Intresset för förnybara bränslen har ökat stadigt under de senaste åren. Att byta ut fossila mot förnybara bränslen kan minska utsläppen av växthusgaser till atmosfären och därmed minska klimatpåverkan av dessa men även minska vårt beroende av olja. Biobränslen som t.ex. etanol, biodiesel eller biogas, räknas till förnybara bränslen eftersom de inte bidrar till en ackumReplacing fossil fuels by biofuels such as ethanol is considered a promising alternative to reduce greenhouse gas (GHG) emissions and mitigate climate change. Biofuels produced from lignocellulosic biomass, so-called second generation biofuels, result in decreased GHG emissions and limit competition with food and animal feed production. Interest in producing ethanol from lignocellulosic biomass ha

Constructing a neural system for surface inspection

Visual quality assurance techniques focus on the detection and qualification of abnormal structures in the image of an object. The features of abnormality are extracted through image mining, whereupon classification is performed on characteristic combinations. Many techniques for feature extraction have been proposed, but the feed-forward neural network is seldom utilized despite its popularity in

Physics of Viral Infectivity: Energetics of Genome Ejection

Popular Abstract in Swedish Virala infektioner är och har varit ett stort hälsoproblem för mänskligheten. Många av de sjukdomar som förorsakas av virus är obotliga och spridningen är oftast snabb (ett exempel är HIV). Förutom att direkt förorsaka olika sjukdomstillstånd har virus också påvisats vara orsak till olika former av cancer. Under de senaste åren har dock forskare försökt att börja använAll viruses that infect bacteria, plant, or animal cells involve a genome (RNA or DNA) that is encapsidated by a rigid protein shell. After delivery of the viral genome into the host cell, new capsid proteins, which are encoded by viral DNA or RNA, are expressed and self-assembled into new viral capsids. The main objective of my research was to study the key physical factors of genome ejection tha

Creep of Heat-cured High-Performance Concrete Subjected to Freezing or Elevated Temperatures

This article outlines an experimental and numerical study of the short-term creep of High-Performance Concrete, HPC, with sealed curing and temperature under freezing point, which is compared with the creep of HPC at normal and elevated temperatures. For this purpose one quality of HPC was studied at 6 different temperatures (-15, -1, 20, 30, 40 and 60 °C) over a period of 66 hours. Parallel studi
