This thesis consists of three empirical studies on the effects of institutions, broadly conceived, on economic outcomes. The first study tests for evidence of causal relationships between provincial quality of governance and economic growth rates in reform-era China, 1985–2005. Improvements in governance are found to be significantly predicted by lagged economic growth rates, while economic growth
Moderna mobiltelefoner är ofta utrustade med olika sensorer som används flitigt bland annat för spel, men som också kan användas i fysikundervisningen. Här analayserar vi accelerometer- och rotationsdata från en iPhone4 som tagits med (i en stängd ficka) i åkattraktionen Lilla Lots på Liseberg.
The reliability of official registers of diagnosis depends on proper adherence to guidelines for diagnosis and diagnosis coding. Such guidelines for severe sepsis and septic shock have changed over the years, reflecting improved knowledge of these serious conditions. In order to investigate the compliance to current Swedish guidelines for diagnosis and coding of severe sepsis and septic shock, we
Asymptotic iterative decoding performance is analyzed for several classes of iteratively decodable codes when the block length of the codes N and the number of iterations I go to infinity. Three classes of codes are considered. These are Gallager's regular low-density parity-check (LDPC) codes, Tanner's generalized LDPC (GLDPC) codes, and the turbo codes due to Berrou et al. It is proved that ther
Artikel gällande handläggning av yrsel på akutmottagningen.The majority of patients who present to the Emergency Department with vertigo suffer from benign conditions. However, a few percent of these patients have life-threatening conditions, such as a cerebellar stroke. The HINTS clinical decision rule (Head-Impulse test, Nystagmus, Test-of-Skew) allows the physician to identify patients with an acute vestibular syndrome of central origin. HINTS is more
Stochastic optimal power flow can provide the system operator with adequate strategies for controlling the power flow to maintain secure operation under stochastic parameter variations. One limitation of stochastic optimal power flow has been that only limits on lineflows have been used as stability constraints. In many systems voltage stability and small-signal stability also play an important role i
Popular Abstract in English Where are we? And what are all the things we have around us? These are questions that we ask as children when we start to discover the world around us. But just because we grow up does not mean that we find the answers to those questions. Around us, we see things as red buses, blue oceans and yellow flowers. But according to science, it is not these things that we fundaA metal nanoparticle can be considered as consisting of a base of positive ion cores and a sea of free electrons. When the free electrons are displaced, for example, by an incident electric field, a restoring force acts on the electrons. The electrons may then oscillate back and forth until equilibrium is reached. This oscillation occurs at the natural frequency, or eigenfrequency, of the system.
Glypican-1 is a glycosylphosphatidylinositol anchored cell surface S-nitrosylated heparan sulfate proteoglycan that is processed by nitric oxide dependent degradation of its side chains. Cell surface-bound glypican-1 becomes internalized and recycles via endosomes, where the heparan sulphate chains undergo nitric oxide and copper dependent autocleavage at N-unsubstituted glucosamines, back to the
