In this paper we describe a simple way of analytically computing entire ìterm structures of default probabilities using information embedded in the corporate bond market data. This market-based approach of estimating the creditworthiness of firms gives probabilities of default at various maturities, and has the advantage over traditional credit ratings in that it is dynamic and forward looking.
Det finns flera anekdotiska bevis för att lärare och studenter anser att det är stor skillnad på naturvetar- och ingenjörsstudenter. För att ge en utgångspunkt för diskussioner på detta tema presenterar vi här en undersökning av två studentgrupper kemitekniker och naturvetare som läst liknande organkemikurs med samma lärare. De första preliminära resultaten visar att skillnaden mellan grupperna fr
Popular Abstract in Swedish Popularized summary in Swedish (Sammanfattning på svenska) Blödarsjuka - hemofili - är en ärftlig sjukdom som endast uppträder hos män och som överföres av kvinnliga bärare vilka ej är blödare. Sjukdomen tar sig uttryck i en abnorm blödningsbenägenhet med framför allt ledblödningar och då redan från tidig ålder. Det finns två typer av blödarsjuka, hemofili A respektiveIn patients with severe hemophilia it is today possible to prevent the development of arthropathy by giving effective continuous prophylaxis from an early age, thus preventing the VIII:C or IX:C concentration from falling below 1% of normal. All the signs show that if a high-dose prophylactic regimen - that is, 3,000-5,000 U/kg body weight annually - is started as early as 1-2 years of age, the pa
The Swedish model of industrial relations is analyzed with respect to some closely related dimensions: collective agreements - legislation, cooperation - confrontation, self-regulation - state regulation and centralisation - decentralisation. Both the historical development and the present state of the model are discussed. In an analytical table the dimension self-regulation - state regulation is
Bats are unique among extant actively flying animals in having very flexible wings, controlled by multi-jointed fingers. This gives the potential for fine-tuned active control to optimize aerodynamic performance throughout the wingbeat and thus a more efficient flight. But how bat wing performance scales with size, morphology and ecology is not yet known. Here, we present time-resolved fluid wake
Samling av svar till de mest förekommande frågorna om Armeniska folkmordet 1915.
The compassion felt by Mary for Christ when she was standing at the foot of the Cross is an important motif in late medieval piety. It becomes an object of liturgical celebration in the fifteenth century and sermons are preached on it. This paper treats the motif in some fifteenth century sermons from manuscripts once owned by the Birgittine abbey of Vadstena, Sweden. The treatment of the motif in
The qualitative approach to research is seen as a socially constructed heterogeneous tradition of ideas. It is difficult to argue for the existence of some set of features which are common to all qualitative methods but not to other types of research methods. Furthermore, it is unfortunate to see the qualitative approach as inherently in contrast to the quantitative approach. In fact, it may be fr
This thesis is based on the work that was done during 1992--1996 at the DELPHI detector at LEP. Its main parts are outlined below. The brief Introduction gives an overview of the science of Particle Physics, its development and contemporary status. The first chapter represents an introduction to the DELPHI detector at LEP, describing the main features of the LEP machine and the DELPHI detector a
Popular Abstract in Swedish Helicobacter pylori och Chlamydia pneumoniae är två mycket vanliga smittämnen i den svenska befolkningen. De vanliga kliniska manifestationerna är magsår respektive luftvägsinfektioner. På senare tid har det också diskuterats huruvida de kan bana väg för sjukdomsmanifestationer även inom andra organsystem. I många fall har de studeras var för sig men betydligt mera sällHelicobacter pylori and Chlamydia pneumoniae are common infectious agents in the Swedish population, causing gastritis ulcers and respiratory infections. The metabolic syndrome is characterised by overweight, insulin resistance, hypertension, diabetes and dyslipidaemia. Sera from a patient cohort (n=531) originally examined in 1987-89 were investigated for previous infection of H. pylori and C. pn
