Hur fungerar en glaselektrod?

To understand the glass electrode needs knowledge from more than one level. The construction ofthe glass electrode is one part, an other is the composition and structure of glass. The Nernstequation have an important role, but also the sources of errors in the analysis and the calibration ofthe glass electrode. Focus for this article is how the glass electrode really works and how Gibbs freeenergy made the potential dependent of the concentration of H+and gives the logarithm to thefunction. Nikolskii's ion exchange theory starts to explain the question about how the potentialcreates and Baucke's dissociation mechanism made it more explicit.

En IT-baserad plattform för skolförbättring : En kvalitativ studie av lärares informations- och erfarenhetsutbyte

This thesis has created an image of the exchange of information among teachers in the Swedish upper secondary school. The study indicates that the exchange of information seems to be limited at all levels and the exchange that takes place outside the own teaching team occurs mainly through teachers personal networks. The study also shows barriers that may exist and the opportunities that an increased exchange may generate. From the picture that the empirical material provides and the theory that is presented a discussion is made around how IT can best support the organizational learning in schools. A concrete proposal is that at national level an IT platform should be created, which primarily focuses on materials that are created by its users and has an open architecture with a single login..

Test av icke-kurssäkrad ränteparitet med fokus på riskpremien och möjliga förklarande faktorer

This thesis aims to evaluate the concept of Uncovered Interest Parity. The parity states that the logarithmic difference between domestic and foreign interest rate equals the logarithmic difference between expected future spot exchange rate and the spot exchange rate, . In defining the exchange rate it is often presumed that the parity relation prevails even though several studies suggest the opposite. Numerous economists maintain that the theory?s shortcomings can be explained through the existence of a Risk Premium.

Effekten av Valutarisk på Bilateral Handel

 This paper evaluates the effect of exchange rate risk on the sum of bilateral trade. To distinguish the effect between different types of countries, two groups are defined: advanced and developing economies. Economic theory on exchange rate risk and trade proposes ambiguous effects of increased volatility. However, the ex ante hypothesis is that developing economies are more sensitive to volatility. Contrarily to the hypothesis, the empirical results suggest that advanced economies would benefit up to twice as much from a removal of exchange rate risk.

"Det ska inte vara lätt att knarka" : En studie om sprututbyte och svensk narkotikapolitik.

Stabil växelkurs och låg inflation - Inbördes oförenliga? En studie av implikationerna av en real appreciering

This paper examines a long run macroeconomic dilemma. This dilemma states that given a real appreciation, i.e. a continuous increase in the real exchange rate, an economy has two options open with respect to inflation and nominal exchange rate. Either the economy chooses a fixed exchange rate- regime but has to allow for a rising inflation. Or the economy can choose an inflation targeting- regime, but then has to allow for an appreciating nominal exchange rate.

Valutamarknadens effektivitet - En studie av växelkurser utifrån UIP med förväntningar

This essay discusses and evaluates the international currency market in regards to efficiency. To prove the theory that, the difference between expected and actual exchange rates is explained by the difference in expected and actual interest rates and the difference in expected and actual inflation between countries, a model was developed. This model was inspired by the paper of Sebastian Edwards (1982), and is based on three theories; UIP, IS/LM and the Efficient Markets Hypothesis. The model uses 16 regressions estimated from three pairs of curriencies: $/SEK, £/SEK and ?/SEK.

En slumpmässig vandring eller genomsnittlig återgång : Råder förutsägbarhet på Stockholmsbörsen?

Utveckling av webbaserad Outlookklient kopplad mot Exchangeserver

Ett nystartat företag ville skapa en hemsida som såg ut och fungerade som Outlook.  Denna sida skulle senare kunna kopplas till Exchange eller något liknande e-postserverprogram. Under arbetets gång så installerades en labbserver med Exchange. När servern var färdig så skulle det gå att koppla upp företaget Teleriks webmaillösning för att sedan kolla om den klarar av Exchange. Målet var att en sida liknande Outlook, till utseende samt funktion, skulle skapas. Denna sida skulle sedan kopplas ihop med en fungerande Exchange server.

Vi behöver prata: en studie om kommunikationen om förväntningar i en nära relation

Detta examensarbete hade som syfte att undersöka hur förmedlingen av förväntningar ser ut i en nära relation. Frågeställningarna handlade om huruvida olika kommunikationsstilar hade någon påverkan och om det fanns skillnader mellan män och kvinnor, eller beroende på hur länge paren hade varit tillsammans, när det gällde förmedlingen av förväntningar i en relation. Social Exchange Theory (Thibaut & Kelley, 1959) har använts som grund för undersökningen eftersom den ger en tydlig förklaringsmodell över förväntningars inverkan på en relations tillfredställelsegrad. Metoden som användes var av kvantitativ art där enkäter var det instrument som tillämpades. Enkäterna fylldes i av 13 par som hade varit tillsammans i minst 6 månader.

"Det bästa med skolan" : En elevinriktad studie om motiv och attityder till internationella utbildningsutbyten.

In Sweden, little research has been done on the topic of international exchange programs that various schools offer to their pupils. This study investigates how pupils view these exchange programs, and how in their opinion it affects their learning and their level of motivation. The study also investigates the motives for taking part in or declining an international exchange. To answer these questions a quantitative survey and qualitative interviews with pupils with and without experience respectively was carried out.The study indicates that pupils that have not taken part in an exchange believe that it is a time consuming quest that may affect the student?s results in other courses, which is not a belief shared by the other group.

Cross-Border Listings and Price Discovery: Evidence from UK- and US-listed Swedish Stocks

Objective: The objective of this study is to examine the extent to which the London stock exchange and the US stock exchange Nasdaq respectively contributes to the price discovery of Swedish stocks listed on the Stockholm stock exchange, the London stock exchange and the US stock exchange Nasdaq.Method: The study is a replicate study of the studies by Grammig, Melvin and Schlag (2000) and Eun and Sabherwal (2003). The methodology is based on the methodology of the latter study. The data material consisting of quoted stock prices for three Swedish stocks on the three stock exchanges at five-minute intervals during a 49-day-period in 2003 has been run through different statistical tests in a five-step process.Conclusion: The evidence of this study shows that prices on SSE, LSE and NASD are cointegrated and mutually adjusting. The evidence suggests that in all three cases, price discovery takes place on the home stock exchange SSE. Moreover, LSE contributes more to price discovery than Nasdaq.
