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.
Evaluation of Different Extraction- and Analysis Methods for Calprotectin in Feces
Background Calprotectin is a protein expressed in the cytoplasm inside the neutrophile granulocytes. During inflammatory bowel disease (IBD), the neutrophile granulocytes are involved in a complex interaction at the inflammatory area where they die and release their content into the intestinal lumen. Therefore, calprotectin in stool is a suitable marker for diagnosis and measurement of the disease-activity in patients with IBD. The most commonly used method to detect calprotectin in stool is ELISA, but the process of manual preparation of stool samples is time-consuming.Aim The objective of the study was to evaluate an extraction method that could replace manual preparation of fecal samples and to compare different methods for measuring Calprotectin in stool using two ELISA-methods from two manufacturers and one rapidtest.Methods For extraction of calprotectin from stool samples we used sample collector tubes from Epitope Diagnostics and fecal preparation kits from Roche. Two different ELISA-kits for measuring calprotectin concentration in stool were compared.
Öppenhet och kostnad för eget kapital: En studie på den svenska marknaden
Previous research has discussed how voluntary disclosure relates to the cost of equity capital. Theories of estimation risk support a negative association between disclosure and cost of equity capital, as empirically documented by Botosan (1997) among others. In this Bachelor thesis we investigate whether such a relationship exists on the Swedish capital market. Using the CAPM to estimate the cost of equity capital and a disclosure index based on Aktiespararen?s annual evaluation of corporate disclosure, we test a model where disclosure explains cost of equity capital.
Högriskfonder kontra aktieindex : En studie av makrovariablers påverkan på olika fondalternativ
Abstract Title: High-Risk Funds vs. Mutual- Index FundsA study of macro -variables influence on different funds choice Level: Final assignment for Bachelor Degree in Business Administration Author: Moses Yokie & Bo Lemar Supervisor: Ogi Chun & Cheick Wagué Date: 2011-05-25 Aim: The purpose with this thesis is to compare two different types of mutual-index fond and a high-risk fund in relation to the macro variables. The purpose also includes an investigation about if an investor will receives a higher return on high-risk fund than on mutual-index fund in a 10 years period.Method: A quantitative method has been use in this study, where the information has been received from Morningstar. Microsoft Excel has been used to process the collected data in order to calculate the expected return and the risk measures. The result is presented in graphs and tables on the empirical capital, in order to analyse and compare it with the theories and the selected macro- variables to see if there will be any correlation. Conclusion: This research shows that there is no possibility that the macro-variable factors can benefit an investment on high-risk fund or on mutual-index fund in the short run.
Pairs trading : En studie på den svenska aktiemarkanden, 1995-2004
Pairs trading is a relatively new trading strategy, the strategy has only been used during a couple of decades. A study made on the American stock market has shown that the strat-egy has generated a positive result. The purpose of this thesis is to investigate if pairs trad-ing has been able to create a positive result on the Swedish stock market during the time period of 1995-2004.The data required for this thesis was collected from Stockholm stock exchange and is ad-justed for splits and issues.The pairs trading strategy involves two stages ? identification of pairs and trading signals. The pairs were identified during a period of 12 months.
Automatisk genreklassifikation : en experimentell studie
This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.
Talet hos femåriga barn med läpp-käk-gomspalt: En jämförelse mellan internationellt adopterade barn och svenskfödda barn
This retrospective study aimed to examine differences at age fivebetween twenty-six internationally adopted and twenty-six Swedish-bornchildren with cleft lip and palate regarding age of surgery, speech andintervention. Correlation between age of surgery and speechvariables andgender differences was examined. Blind assessment of audio recordedsentence repetition or naming of words was performed by two speechpathologists. Soft palate was closed significantly later for the study groupthan the control group. Age at closure of hard palate did not differ.
Upplevelser samt erfarenheter ifrån det kulturellt blandade projektet PEGASUS
Dagens arbetsplats blir alltmer internationell och därmed multikulturell. Medarbetare med skilda arbets- och tillvägagångssätt, idéer, traditioner och normer möts på nya sätt och i nya situationer. För att dessa kulturmöten ska bli givande och stimulerande för alla parter, finns behovet av en medvetenhet för de kulturella skillnaderna. Denna studie är en beskrivning av vilka upplevelser och erfarenheter som fanns inom det kulturellt blandade projektet, ?Pegasus? på Skanska Sverige AB.
Kapitalkostnaden på Stockholmsbörsen: En studie av marknadens implicita riskpremie i hög- och lågkonjunktur, samt hur den implicita kapitalkostnaden korrelerar med kapitalkostnaden enligt CAPM
This thesis explores some issues regarding estimations of the cost of capital on the Stockholm Stock Exchange through reverse engineering of the Residual Income Valuation model and through usage of the Capital Asset Pricing Model. Previous studies are in conflict of whether the risk premium changes considerably over time or not. Furthermore, the risk premium estimated by CAPM tends to be fairly stable. In this study, reverse engineering of the cost of capital implied by analysts? forecasts shows a significant difference in the risk premium over time.
MIMO kanalmodeler
The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

Upplevelser av skam och avvisande hos deprimerade unga vuxna
Depression in young adults is a serious condition causing serious suffering for the victim. By finding risk factors for depression the opportunity for early preventive action is increased, which, in turn, may prevent a negative course. Two risk factors which have been shown to be related to depression are shame and rejection. Therefore this study examined the relationship between shameproneness, rejection sensitivity, shame-related events and depressive symptoms. The self-report questionnaires used were TOSCA, RSQ, Shaming index and BDI-II.
