The objective of this study is to discover the sources of securities return in forecasting stock return from different sides of potential factors including fundamental and market information. We test currency sensitivity, earnings variability, earnings yield, growth, leverage, trading activity, momentum, size, value, volatility, capital spending discipline, free cash flow, efficiency, solvency, earnings quality, corporate finance policy and technical 17 factors basing on different factor dimensions in this study. We construct a Taiwan multi-factor model by using the most significant factors for universal stocks according to 0HMSCI Barra¡¦s Multiple-Factor Modeling process, and then apply market neutral investment to build portfolios for performance back-testing. As a result, the most significant top five factors in forecasting are respectively ¡§Volatility2,¡¨ ¡§Earnings Quality1,¡¨ ¡§Trading1,¡¨ ¡§Volatility1¡¨ and ¡§Growth1¡¨ factors. In addition, we find the most useless bottom four factors in forecasting are respectively ¡§Size1,¡¨ ¡§Earning Yield1,¡¨ ¡§Value1,¡¨ and ¡§Capital Spending1.¡¨ No matter which strategies we adopt to build the portfolio, the Sharpe ratios of back-testing performance are all higher than the Benchmark, and all bring stable and consistent performance. It actually proves that this model is robust.

The k-LCS problem is to find the longest common subsequence (LCS) of k input sequences. It is difficult while the number of input sequences is large. In the past, researchers focused on finding the LCS of two sequences (2-LCS). However, there is no good algorithm for finding the optimal solution of k-LCS up to now. For solving the k-LCS problem, in this thesis, we first propose a mixed algorithm, which is a combination of a heuristic algorithm, genetic algorithm (GA) and ant colony optimization (ACO) algorithm. Then, we propose an enhanced ACO (EACO) algorithm, composed of the heuristic algorithm and matching pair algorithm (MPA). In our experiments, we compare our algorithms with expansion algorithm, best next for maximal available symbol algorithm, GA and ACO algorithm. The experimental results on several sets of DNA and protein sequences show that our EACO algorithm outperforms other algorithms in the lengths of solutions.

<p>This thesis investigates in what way trade flows in Europe have been altered and differ for countries belonging to a preferential trade agreement as well as a common currency area. More specifically, how exports among the European countries are affected by memberships with the European Union and the EMU. A total of 72 countries have been chosen which represents the main trading partners between the EU and the rest of the world. Out of these 72 countries, 25 represent EU members which include 12 EMU member countries.</p><p>The econometric analysis employ a gravity model with 18 variables in order to determine their impact on trade flows. This is done through a regression with a log-log equation where the dependent variable is export. The other variables included are chosen to explain export flows among the EU members as well as their trade with EMU countries and the rest of the world. Furthermore, variables representing trade affinities are included to determine whether or not they have a significant effect on trade.</p><p>The regression is divided into four time periods in order to more easily determine how the trade pattern in Europe have altered from the establishment of the EU and the EMU. The first time period represent an early state of EU membership, the second a mature state of EU membership, the third when EU was reformed and the fourth an early state of EMU membership.</p><p>The regression results illustrate that the majority of the selected variables are significant but most importantly that the trade affinity variables are proven to have an impact on trade flows. The results also show that trade has increased and that in the case of EU membership it is more profitable to join than to remain outside. Moreover, the result show in par-ticular that countries that belong to the EMU have a stronger orientation of their exports to the rest of the world then other EU countries. For the latter, the European market is of prime importance.</p>

<p>Since the end of World War II, foreign direct investment (FDI) has been leading the international financial capital flows and has tripled in 2000s over the decade earlier. With its positive effect on economic growth of host countries via spill-overs, it became a race among countries to attract multinational enterprises (MNEs) to invest in their countries. The introduction of European common currency theoretically helps reduce the transaction costs across borders with the reduction of exchange-rate uncertainties and associated costs of hedging, facilitation of international cost comparison. Moreover, mergers and acquisitions activities (M&As) account for 60-80% of FDI flows, and most MNEs engage in both export and setting up affiliates abroad, suggesting complementarity between trade and FDI. Thus reducing cross-border distance costs would encourage MNEs to increase its M&A activities abroad, resulting in more inward FDI flows in the eurozone, especially among member states. The gravity equation is used in this paper to estimate the euro effect from the dataset of inward FDI flows of 24 countries during 1993-2007 and the result confirms that common currency stimulates more intra-eurozone inward FDI flows by approximately 58%.</p>

<p>En designers främsta uppgift är att hitta lösningar på problem som är svårformulerade vilket kräver full förståelse för designsituationen. Interaktionsdesignern fungerar dessutom som länk mellan olika aktörer i en beställarprocess med syfte att tillgodose slutanvändarens behov, som ofta faller mellan stolarna. Avsikten med denna rapport är att studera hur interaktionsdesignern kan vara den kommunikatör som krävs. Detta har gjorts genom att titta på hur objekt används i kommunikationen mellan designern och dess klient. Studien är gjord genom en videoanalys som tolkats utifrån Herbert H. Clarks kommunikationsanalytiska termer. Common ground används som representation för den ömsesidiga förståelse som här önskas belysas. Videomaterialet är hämtat från ett större forskningsprojekt där olika designgrupper tillsammans med kronofogdemyndigheten arbetar i workshops för att ta fram ett nytt IT-stöd.</p><p>Objekt visar sig vara viktiga verktyg för att orientera sig i ett samtal och för att representera information. De blir därmed viktiga för att hänvisa till common ground och säkra dess innehåll. Det är viktigt att lyfta interaktionsdesignerns roll för slutanvändaren och de verktyg och metoder denne kan behöva för att kommunicera och hitta lösningar på designproblem. Det finns därmed behov av fungerande ramverk för studier kring kommunikation, vilket visar sig kräva mer kunskap.</p>

There is a tendency within intersectional blogging discourse for settlers to ignore the ongoing colonial process occurring on Turtle Island. This pattern is bound up in a settler common sense that understands settler occupancy as inherent and natural. Such an approach to intersectional-type work ignores the manner in which all oppressive actions on Turtle Island are occurring on Indigenous lands. Regardless of a settler’s intersections, their presence on Indigenous lands indicates that they are implicated in an ongoing process of colonization. This thesis identifies and examines how intersectional bloggers are writing about issues pertaining to Indigenous peoples and nations. It is argued that through the exploration of Indigenous feminist writing, intersectional settler blogging has the potential to work towards decolonization and solidarity with Indigenous nations. This thesis draws from the work of Indigenous feminist blogs in order to gain insight on how settlers can begin to decolonize their own work. / Graduate

This dissertation aims at investigating the association between genotypes and phenotypes in human. Both common and rare regulatory variants have been studied. The phenotypes include disease risk, clinical traits and gene expression levels. This dissertation describes three different types of association study. The first study investigated the relationship between common variants and three sub-clinical traits as well as three complex diseases in the Center for Health Discovery and Well Being study (CHDWB). The second study is GWAS analysis of TNF-α and BMI/CRP conducted as a contribution to meta-GWAS analyses of these traits with investigators at the University of Groningen in the Netherlands, and the 1000 Genomes Consortium. The third study was the most original contribution of my thesis as it assessed the association between rare regulatory variants in promoter regions and gene expression levels. The results clearly show an enrichment of rare variants at both extremes of gene expression. This dissertation provides insight into how common and rare variants associate with broadly-defined quantitative phenotypes. The demonstration that rare regulatory variants make a substantial contribution to gene expression variation has important implications for personalized medicine as it implies that de novo and other rare alleles need to be considered as candidate effectors of rare disease risk.
