Background & Aims: Oxidative stress and apoptosis are proposed mechanisms of cellular injury in studies of xenobiotic hepatotoxicity. The aim of this work is to find early signal markers of drug-induced injury of the liver by focusing on select antioxidant/oxidant and apoptotic genes. As well, to address the relationship between conventional liver dysfunction markers and the measured mRNA and protein expressions in the D-galactosamine/lipopolysaccharide and tert-butylhydroperoxide hepatotoxicity models. Furthermore, potential hepatoprotective capabilities of antioxidant polyphenols quercetin and curcumin were evaluated in relation to its modulation of the oxidative stress and apoptotic parameters in the given xenobiotic hepatotoxicity models. Methods: Biochemical markers testing the hepatic function included aminotransferases (ALT, AST) and bilirubin. Measurements of TBARS and conjugated dienes were used to assess lipoperoxidation. Plasma levels of catalase and reduced glutathione were used as indicators of the oxidative status of the cell. Real time PCR was used to analyse the mRNA expressions of the inducible nitric oxide synthase (NOS-2), heme oxygenase-1 (HO-1), superoxide dismutase (SOD-1), glutathione peroxidase (Gpx-1), caspase 3 (Casp3), BH3 interacting domain death agonist (Bid) and Bcl-2...

The topics are distributed in two subareas, microstructure and asset pricing. There is also an insertion of the study in corporate finance, since we deal with the corporate governance of firms. In the first chapter I estimate the adverse selection cost component embedded in the spreads of Brazilian stocks. I also study the patterns of spreads and adverse selection costs as a function of the size and time of the trade. In chapter two, I implement an extensive research through a series of regressions in order to determine characteristics of the companies that are correlated with the adverse selection component and the spread. In particular, we analyze the relationship between the adverse selection and corporate governance levels. In the third chapter I detect which corporate governance mechanisms cause an opposite relationship between the returns of Brazilian stocks and corporate governance levels, as shown by Carvalhal and Nobili (2011). In this analysis, I emphasize the ownership concentration of Brazilian companies, which is extremely high when compared with more developed countries. / Esta tese se dedica a estudos na área de finanças. Os estudos se subdividem nas subáreas de microestrutura e apreçamento de ativos, mas há uma inserção do trabalho em finanças corporativas, uma vez que trato da governança corporativa das empresas. No primeiro capítulo estimo o coeficiente de assimetria de informação embutido no spread de compra e venda de ações brasileiras. Além disso, verifico se há padrões para esse coeficiente e para o próprio spread em relação ao tamanho da transação e à hora de negociação. No capítulo dois, eu investigo quais características ligadas às empresas têm relação com as variáveis estimadas no capítulo 1, o coeficiente de assimetria de informação embutido no spread de compra e venda de ações brasileiras e o próprio spread. A governança corporativa das empresas é uma das características examinadas. No terceiro capítulo, eu observo quais mecanismos de governança corporativa fazem com que haja uma relação antagônica entre os retornos das ações brasileiras e o índice de governança corporativa, conforme mostrado por Carvalhal e Nobili (2011). Nesta investigação, dou ênfase à concentração acionária das empresas brasileiras que, em comparação com países mais desenvolvidos, é extremamente alta.

La thèse a été évaluée par les personnes suivantes: Carlo Morselli, directeur de recherche et professeur à l'École de criminologie; Anthony Amicelle, président du jury et professeur à l'École de criminologie; Jean Bérard, membre du jury et professeur à l'École de criminologie; Carla Nagels, évaluatrice externe et professeur à l'Université libre de Bruxelles L'auteur aimerait remercier le Fonds de recherche du Québec - Société et culture (FRQSC), le Centre international de criminologie comparée (CICC) et l'École de criminologie pour le support financier octroyé à différentes étapes de la rédaction de la thèse. / La recherche trouve ses origines d’un scandale touchant l’industrie de la construction et les milieux politiques au Québec de la fin des années 2000 (à travers les allégations de corruption et de collusion soulevées par les médias) à la fin novembre 2015 (avec le dépôt du rapport final de la Commission d’enquête sur l’octroi et la gestion des contrats publics dans l’industrie de la construction, ci-après CEIC). L’argument principal est que les années de scandale ont permis au Québec de transiter d’une province considérée comme la terre mythique de la corruption au Canada à une entité développant une des structures anticorruptions les plus novatrices et sophistiquées dans le monde. La thèse est construite comme une étude de cas qui s’intègre aux trois grandes sphères de l’étude du phénomène criminel telles que définies par Sutherland et Cressey, à savoir le passage à l’acte, la réaction sociale et le contrôle social (1947, p.1). Dans l’étude du passage à l’acte, le concept de crime étatico-corporatif est mis à profit afin d’exposer l’aspect symbiotique des systèmes criminels alimentés à travers une interaction fondamentale entre poursuite d’intérêts publics et poursuite d’intérêts privés. De tels systèmes furent en effet identifiés dans plusieurs municipalités du Québec. Pour cette partie de la thèse, les données relatives à l’ensemble des contrats de construction octroyés par appel d’offres public par la ville de Laval dans son histoire (1965-2013) sont analysées à travers diverses mesures de réseaux sociaux. Cette portion de la thèse utilise également les témoignages issus des travaux de la CEIC, et des entretiens semi-directifs réalisés avec des acteurs provenant de diverses autorités de lutte à la collusion (truquage des appels d’offres) et à la corruption au Québec. La combinaison de ces méthodes permet d’évaluer la nature intégrée, historique et spatiale des délinquances recensées au sein de diverses municipalités, avec des indicateurs de collusion qui remontent aussi loin qu’à la création de la municipalité lavalloise dans les années 1960. Dans l’étude de la réaction sociale, un modèle d’analyse intégratif emprunté au domaine de la sociologie de l’action publique (Lascoumes et LeGalès, 2012) est utilisé pour mettre en relief les forces structurelles, organisationnelles et individuelles derrière la constitution du scandale québécois. Cette deuxième grande section de la thèse illustre comment ce scandale s’insère dans des tendances nationales et internationales d’intolérance accrue du public et d’intensification des contrôles à l’égard des actes criminels (corruption, collusion, pots-de-vin, fraude) révélés au coeur du scandale. Enfin, dans l’étude du contrôle social, l’analyse des témoignages issus des audiences de la CEIC est jumelée aux données découlant d’entretiens semi-directifs réalisés avec 22 acteurs provenant d’agences de contrôle créées à la suite du scandale : l’Unité permanente anticorruption (UPAC), le Bureau de l’inspecteur général (BIG) de la ville de Montréal, et le Bureau d’intégrité et d’éthique de Laval (BIEL). Cette dernière section illustre comment la transition d’une scène réglementaire permissive et hautement déficiente à un environnement réglementaire axée sur une mobilisation sans précédent de ressources policières, sur le partage d’information et sur la poursuite des conduites illégales au pénal s’avère très avantageuse, mais s’est accomplie – et s’accomplit toujours – à travers de nombreux défis pour les contrôleurs. / The research originated from a political scandal which spanned several years (2009-2015) in the province of Quebec. The thesis’ main argument is that the scandal years saw Quebec transformed from being considered the “historical golden land” of Canadian corruption into a province which developed one of the country’s most sophisticated systems of corruption and white-collar crime control. The thesis was constructed as a case-study, and addressed the three principal objects of criminological analysis: the breaking of laws, the making of laws, and the reaction to the breaking of laws (Sutherland and Cressey, 1947, p.1). The study applied multiple methods to achieve these goals. In the study of criminal decision-making (breaking of laws), Kramer and Michalowski’s (2006) state-corporate crime concept was applied to demonstrate the presence of multifactorial features of criminal systems fuelled by misbehaving at the intersection of private and public interests. Such conspiracies were found to be generalized across several municipalities throughout the province. For this portion of the thesis, data on all construction contracts awarded through public procurement in the entire history of what appeared to be one of Canada’s most corrupt municipalities, Laval (the 13th largest in the country), was systematically collected from 1965 to 2013. It was then analyzed using various social network measures. Testimonies from Quebec’s Commission of inquiry on the awarding and management of public contracts in the construction industry (hereafter, CEIC) were also coupled with a dozen of interviews conducted with regulators and corruption authorities in Quebec. The combination of methods helped assess the integrated, spatial and historical nature of illicit activities which undergirded many municipalities, Laval being one of the most notorious one. Traces of bid-rigging indicators in public procurement were indeed traced back to as early as the city’s founding in the 1960s. In the study of the making of laws, Lascoumes and Le Galès’ (2002) sociology of public action framework was expanded to investigate the structural, organizational, and individual forces behind the Quebec scandal. This section of the thesis unravels the sudden urge to legislate and investigate schemes that were deeply rooted in the province’s history. By making sense of the Quebec scandal, this sub-section demonstrates how larger structural and contextual factors gradually established increased incentives for elected officials to enhance legal and institutional controls on white-collar and corporate crimes which were found to be systemic across Quebec’s construction and political scenes. Finally, in the study of the reaction to the breaking of laws, testimonies from the CEIC were combined with interviews conducted with 22 actors in control agencies established as a direct result of the scandal: the Permanent Anticorruption Unit (UPAC in French), the Inspector General Bureau (BIG in French) of the city of Montreal, and the Bureau of integrity and ethics of Laval (BIEL in French). This last section shows how transitioning from a state of practical passivity to one of intense controls, monitoring, institutional rearrangements, and legislative efforts was accompanied, for regulatory and police authorities, by several benefits but substantial challenges as well.

This work deals with the bid price for a development project base on the construction of houses funded by a private German investor. The bid price create with help of budget in a various structures. The various structures of the budget, which use in German environment usually. Specifically, it uses the norm DIN 276 and classification StLB includes software. The main target of my diploma thesis is suggestion for create the bid price. The suggestion with choose form and manner of valuation build works, which respect all legislation for realization construction in Germany.

This dissertation analyse selected used methods of appraising of flats and their reciprocal comparing.

There were selected flats with differeent layout.

True market prices of real estates, unlike bid prices, are often hard to reach. Nevertheless, this information is necessary for many direct and indirect real estate market subjects, especially for valuation purposes. Therefore the bid prices of concrete real estates are often used, but they are not generally equivalent market prices. And so it´s necessary to find some way to convert bid prices to market prices. This dissertation thesis shows definite approach to this issue. Market price and bid price rate is estimated by multi-dimensional linear regression model and non-linear estimations of simple regression. Multi-dimensional linear regression model estimates the values of this rate from other variables, like supply duration, price line according to localities and other. Non-linear estimations of regression function were used for the trend bid and market price modelling in dependence on number of the population in various localities.

Public procurement amounts to a significant part of Sweden's GDP. Nevertheless, it is an overlooked sector characterized by low digitization and inefficient competition where bids are not submitted based on proper mathematical tools. This Thesis seeks to create a structured approach to bidding in cleaning services by determining factors affecting the participation and pricing decision of potential buyers. Furthermore, we assess price prediction by comparing multiple linear regression models (MLR) to support vector regression (SVR). In line with previous research in the construction sector, we find significance for several factors such as project duration, location and type of contract on the participation decision in the cleaning sector. One notable deviant is that we do not find contract size to have an impact on the pricing decision. Surprisingly, the performance of MLR are comparable to more advanced SVR models. Stochastic dominance tests on price performance concludes that experienced bidders perform better than their inexperienced counterparts and companies place more competitive bids in lowest price tenders compared to economically most advantageous tenders (EMAT) indicating that EMAT tenders are regarded as unstructured. However, no significance is found for larger actors performing better in bidding than smaller companies. / Offentliga upphandlingar utgör en signifikant del av Sveriges BNP. Trots detta är det en förbisedd sektor som karakteriseras av låg digitalisering och ineffektiv konkurrens där bud läggs baserat på intuition snarare än matematiska modeller. Denna avhandling ämnar skapa ett strukturerat tillvägagångssätt för budgivning inom städsektorn genom att bestämma faktorer som påverkar deltagande och prissättning. Vidare undersöker vi prisprediktionsmodeller genom att jämföra multipel linjära regressionsmodeller med en maskininlärningsmetod benämnd support vector regression. I enlighet med tidigare forskning i byggindustrin finner vi att flera faktorer som typ av kontrakt, projekttid och kontraktsplats har en statistisk signifikant påverkan på deltagande i kontrakt i städindustrin. En anmärkningsvärd skillnad är att kontraktsvärdet inte påverkar prissättning som tidigare forskning visat i andra områden. För prisprediktionen är det överraskande att den enklare linjära regressionsmodellen presterar jämlikt till den mer avancerade maskininlärningsmodellen. Stokastisk dominanstest visar att erfarna företag har en bättre precision i sin budgivning än mindre erfarna företag. Därtill lägger företag överlag mer konkurrenskraftiga bud i kontrakt där kvalitetsaspekter tas i beaktning utöver priset. Vilket kan indikera att budgivare upplever dessa kontrakt som mindre strukturerade. Däremot finner vi ingen signifikant skillnad mellan större och mindre företag i denna bemärkning.

Diese Dissertation zielt darauf ab, ein besseres Verständnis für Anomalien und Insiderhandel zu schaffen, sowie die Verfügbarkeit von qualitativ hochwertigen Daten für den deutschen Aktienmarkt zu verbessern. Der erste Aufsatz beinhaltet eine verzerrungsfreie Zeitreihe von monatlichen Renditen deutscher Aktien für die Jahre 1954 bis 2013, die auf der Basis stabiler Regeln berechnet und gut dokumentiert ist. Im Weiteren enthält der Aufsatz eine detaillierte Beschreibung des deutschen Aktienmarktes und dessen Besonderheiten, insbesondere im Vergleich zu den USA. Der zweite Aufsatz zeigt am Beispiel des Fama/French Drei-Faktoren-Modells die Probleme auf, die Anbieter und Nutzer von Faktorendaten haben, die sich nicht auf die USA beziehen. Die empirische Analyse von sieben Faktorensets für Deutschland zeigt, dass die Übernahme von Faktormodellen in einen anderen Kapitalmarkt eine komplexe Thematik ist. Der Aufsatz gibt Anregungen für Nutzer und Anbieter von Faktorensets und zeigt, wie die Wahl des Faktorensets das Ergebnis einer Studie beeinflussen kann. Im dritten Aufsatz werden verschiedene zyklische und antizyklische Handelsstrategien hinsichtlich ihrer Performance im deutschen Aktienmarkt untersucht. Von den untersuchten Strategien erscheint nur Momentum konsequent abnormale Renditen zu erzielen, dies auch nach Transaktionskosten. Die vierte Arbeit untersucht öffentlich bekannt gegebene Aktientransaktionen von Insidern börsennotierter deutscher Unternehmen. Der Aufsatz zeigt, dass Insider von TecDAX-Unternehmen und ihre Imitatoren hohe und statistisch signifikante abnormale Renditen erzielen. Insgesamt zeigt die Dissertation, dass methodische Variationen, die Verwendung verschiedener Untersuchungsdesigns, die Datenqualität und die Sorgfalt beim Erstellen von empirischen Analysen zur Beurteilung der Robustheit und der Stabilität der Ergebnisse unerlässlich sind. Der deutsche Aktienmarkt scheint effizienter zu sein als bisherigere Studien typischerweise nahelegen. / This doctoral thesis aims to contribute to a better understanding of stock market anomalies and insider trading as well as to improve the availability of high quality data for the German stock market. The first paper provides a sixty-year time series of monthly returns on German stocks that is constructed on the basis of stable rules, is well documented, includes all return components, and is free of biases. The paper also contains a detailed description of the German stock market, its peculiarities, regulation and differences as compared to the U.S. The second paper uses the Fama/French three-factor model as an example to point out the problems that providers and users of non-U.S factor data sets face. The empirical analysis of seven different factor data sets available for Germany shows that exporting a specific factor model from the U.S. to another capital market is neither an easy nor well-defined task. The paper gives suggestions to users and creators of factor sets and shows how the choice of a factor set affects the result of an empirical study. The third paper provides evidence on how various contrarian, momentum and seasonality strategies perform in the German stock market. Among these strategies, only momentum investing appears to earn persistently non-zero returns, even after transaction costs. The fourth paper studies publicly disclosed stock transactions by insiders of listed German firms. The paper finds that insiders of TecDAX firms earn large and statistically significant abnormal returns net of transaction costs; for DAX insiders they are indistinguishable from zero. Overall, this thesis illustrates that methodological variations, the use of different specifications, data quality and care when preparing empirical analyses is essential in the assessment of the robustness and stability of results. In sum, the German stock market appears to be more efficient than previous studies have typically suggested.

To create a more completed financial market, Taiwan Futures Exchange (TAIFEX) will issue "the Taiwan stock index option" recently. As the complex and various features of the options trading, the option market will be successful and efficient through the market maker's economic functions, which are adding liquidity, increasing price efficiency, transferring risk and proving price information. This survey tried to compare the different functions of market maker system with TAIFEX, EUREX, SEHK and LEFFE, and to disclose the influence of the new market maker system on Taiwan's option market. This exposure takes great interest in market maker's knowledge and technology. By summarizing and classifying the operation process cycle flow of market maker, this research further organizes an analytic structure in market maker's risks. Including the market making risks and the positions management risks, the discussion demonstrates the market change risk, pricing strategy risk, limitary quoting risk, market volatility risk, hedging risk, mechanism risk, and finance and operation risk. The consequent also furnishes the concerns about the future development of Taiwan option market, emphasizing the importance of the relationship between market makers and market' benefit, and the suggestions to the further research.
