This project investigates if access to a solar powered calculator improves numeracy and who benefits the most from the use of a calculator. A randomized field study was carried out in two different high schools in Palawan, a province in the Philippines. All participating students took two identical mathematics tests based on mental arithmetic, the first at the initial stage and the second seven we
I mer än 40 år har det pågått en diskussion om huruvida EU kan och bör ansluta sig till den Europeiska konventionen om skydd för de mänskliga rättigheterna och de grundläggande friheterna, (EKMR, konventionen). Efter Lissabonfördragets ikraftträdande finns numera till och med en fördragsstadgad skyldighet för unionen att ansluta sig till konventionen. Av den anledningen förhandlade EU-kommissionen
Syftet med detta examensarbete är att pressentera ett antal tekniska lösningar för att förbättra säkerheten och kapaciteten i ställverk 59. Ställverk 59 är den vanligaste ställverkstypen på Trafikverkets järnvägsnät. Grundkonstruktionen är utvecklad på 1950-talet, men ställverkstypen nybyggs fortfarande trots konstruktionens ålder. Ända sedan järnvägen infördes har det funnits behov av att styra t
Denna uppsats bidrar med att bygga vidare på forskningen kring att investera efter direktavkastning (utdelning/aktiepris) på den svenska aktiemarknaden. Syftet med uppsatsen är att testa om man kan slå mitt valda index OMXS30 med tre varianter av Dogs of the dow strategin, men också om man kan påvisa några signifikanta skillnader mellan dessa tre likartade portföljsvalsstrategier,som skiljer sig i
Swedish translation (by B. Stolt) of select sermons by John Tauler (c. 1300-1361). A selection was made from among the authentic texts in Middle German.
The traditional presentation about historical time-passing consists in a linear succession of facts in which some aspects of the life world evolve from others in an irreversible manner. The presentation of change is connected to the presentation of gradual or revolutionary linear changes that are irrevocable. I believe that this presentation could be considered correct for living organisms, but do
Measurement of antibody titres to the human polyomaviruses BK and JC has for many years had to rely on Hemagglutination inhibition. In recent years, viral serology based on virus-like particles (VLPs) in enzyme immunoassays (EIAs) has become widely used for a variety of viruses. We sought to establish a modern method for serological diagnosis of BK and JC viruses, by using purified VLPs containing

Examples of Fell algebras with compact spectrum and trivial Dixmier-Douady invariant are constructed to illustrate differences with the case of continuous-trace C∗-algebras. At the level of the spectrum, this translates to only assuming the spectrum is locally Hausdorff (rather than Hausdorff). The existence of (full) projections is the fundamental question considered. The class of Fell algebras s
Background: Treatment of common bile duct (CBD) stones after Roux-en-Y gastric bypass (RYGB) poses a particular challenge given the altered anatomy and inability to perform a standard endoscopic retrograde cholangiogram (ERC). The optimal treatment strategy for intraoperatively encountered CBD stones in post-RYGB patients has not been established. Objectives: To compare outcomes following laparosc
During times of crisis, such as the COVID-19 pandemic, policymakers and the public reveal a strong preference for fairness in pricing even when that would reduce efficiency. For example, they support the application of price gouging laws that prevent prices for necessities from skyrocketing but probably also dampen incentives for firms to produce more and alleviate the shortage. More generally, a
This article suggests a model for lexical verb semantics that unifies Halliday’s model for transitivity with Langacker’s concept of base and profile and also with a model for situation type (cf. Smith 1997). It is claimed that verbs adhere to one of four macro domains: the material, the social, the mental or the relational domain. Within these domains there are numerous types of verbs, such as mot
