The Térapa fossil vertebrate site, northcentral Sonora, Mexico, provides a rare opportunity to study the paleoenvironmental conditions present in northwestern Mexico during mid-Oxygen Isotope Stage (OIS) 3. Ostracode faunal assemblages and stable oxygen (δ18O) and stable carbon (δ13C) isotope values from ostracode calcite were used to reconstruct the seasonality of precipitation and vegetation cover at Térapa at 40-43 ka. The ostracode fauna was a non-analogue mix of temperate and tropical ostracode species composed of 13 species from 12 genera. The nearctic ostracodes Fabaeformiscandona caudata, Physocypria pustulosa, Cypridopsis vidua and the cosmopolitan ostracode Darwinula stevensoni dominate the assemblage. Two tropical ostracode genera, Chlamydotheca arcuata and Stenocypris sp., were present throughout the deposit and indicate that mean monthly summer temperatures were probably no more than 4°C to 6°C cooler than at present, based on available ecological information. Winter precipitation dominated the hydrologic cycle as evidenced by low ostracode δ18O values (-6‰ to -8‰ VPDB). Low ostracode δ13C values (-7‰ to -8‰ VPDB) suggest that local vegetation was dominated by C3 plants. A previous tooth enamel-based paleoenvironmental reconstruction at the same site favored a summer-dominated or evaporative hydrology and abundant C4 vegetation. The Térapa megafauna site exemplifies the need for multi-indicator paleoclimate reconstructions in desert environments where marked differences in the seasonality of precipitation and vegetation cover may occur.

The main contribution of the diploma thesis is to give a comprehensive picture of the switch from LIBOR to OIS discounting. Prior to the global financial crisis, LIBOR (London Interbank Offered Rate) represented an approximation of the risk-free rate in the valuation of interest rate derivatives. The collapse of Lehman Brothers in 2008 resulted in sharp widening of the LIBOR-OIS spread, an indicator of the interbank market stress. Many derivative practitioners have become concerned about the choice of an appropriate risk-free rate. Traditional valuation approaches using LIBOR discounting have been reviewed. Meanwhile, the OIS (Overnight Indexed Swap) rate has become a better proxy for the risk-free rate, at least for collateralized or centrally cleared transactions. Firstly, the research aims to discover the divergences between LIBOR rates, popular pre-crisis proxies for the riskfree rate, and OIS rates, their post-crisis alternatives. Secondly, it covers the interbank lending market, and analyzes individual LIBOR-OIS spreads for the USD, EUR, GBP and CZK currency. Thirdly, it explores the transition to OIS discounting in connection with an influence on a wide spectrum of interest rate derivatives. Therefore, any potential effects are demonstrated on numerical valuation examples of interest rate swaps in the USD, EUR, and GBP currency. Finally, the diploma thesis addresses a topic of collateral management and clarifies different approaches using LIBOR or OIS rates for collateralized or non-collateralized transactions.

This thesis presents how and if open innovation software (OIS) supports different types of creativity. The relevant theories and information on how an OIS is designed and, the relevant theories of creativity are used for making a model to test on different OIS. The result shows that most OIS functionality supported the structuralist and situationalist school of creativity but it also shows that the inspirationalist school was poorly supported in the current functionality. With the result we discuss the implications of supporting all types of creativity to support the most of the users and in the end enable more innovations.

The goal of this master thesis is to analyze main changes affecting interest rate swaps in the Czech republic, which took place since 2007, in areas of regulation, valuation of interest rate swaps and negative interest rates. The first part defines derivative and describes sort of derivatives and type of swaps. The second part deals with interest rate swaps, pricing and valuation, and contractual documentation. The third part explains the impact of regulation MiFID I, EMIR and MiFID II on interest rate swaps. The fourth part analyzes changes in interest rate swaps valuation and negative interest rates issues.

Flank margin caves of the Bahamas are formed by mixing dissolution in a fresh-water lens. As they evolve, the probability of intersecting neighboring voids increases, and they enlarge in a nonlinear fashion. Large flank margin caves become constrained by surface topography and their morphology is influenced by the shape of the enclosing land mass as a result. High phreatic ceilings can be dissolved if the fresh-water lens is distorted by lithological heterogeneities or hydrologic loading due to storm events. Early diagenesis of the host rock causes the reorganization of porosity and permeability through dissolution and cementation processes. Meteoric overprinting occurs but cannot be used as a tool in determining the age of eolianites or the climatic conditions at the time of deposition. Current evidence indicates an OIS 5e speleogenesis of large flank margin caves. An OIS 11 origin can be advanced only with compelling evidence of a pre-OIS 5e highstand.

This thesis offers a reassessment of Pieter Bruegel the Elder’s painting Children’s Games (1560, Kunsthistoriches Museum, Vienna). Addressing the lack of historically accurate interpretations of Bruegel’s panel, I use a wide range of sixteenth-century sources to develop fresh insights into how the work might have been understood by its original audience. The Introduction opens with a description of the painting’s iconography, provenance, current condition and conservation history. A review of previous literature relating to the panel sets Children’s Games within the trajectory of scholarship on Bruegel and other related works in his oeuvre and serves to highlight areas of scholarly difficulty and disagreement as well as current methodological trends. Considering the reception, rather than the inception, of Children’s Games, the third part of the Introduction outlines broader cultural developments which shaped habits of looking in the sixteenth century, including encyclopaedic texts, atlases, Wunderkammern and memory systems. Surmising that Bruegel’s viewers would have been adept at searching for arguments within abundant collections of material, I then introduce a number of sixteenth-century sources which detail contemporary attitudes towards game-playing. The Introduction ends with an outline of the structure and methodological approach of the thesis. Chapter 1, 'Artistic Precedents: Illuminated Manuscripts', considers the panel in relation to the iconography of popular games found in the borders of illuminated manuscripts produced in France and the Netherlands in the late fifteenth and early sixteenth century. After highlighting areas of shared iconography, I discuss how Children’s Games differs from illuminated manuscripts, concluding that Bruegel rejected the 'game of the month' tradition found in the calendar borders and instead amalgamated a variety of children’s games and festive customs to create a humanistic encyclopaedia of children’s culture. A second sixteenth-century source which details popular games is François Rabelais’s book Gargantua (1532). Chapter 2 presents my research into why Rabelais’s writing is relevant to Bruegel scholarship, including archival evidence that Rabelais’s books were available in Antwerp and an analysis of the Songes drolatiques de Pantagruel (1565), a collection of woodcuts which combined Rabelais’s name with Bruegelian imagery. I then compare Children's Games with the list of 217 popular games played by Gargantua and discuss how these fictional lists related to the factual compilations of the period. Gargantua’s game-list occurs in the context of his humanist education, a context which is also relevant to Bruegel’s panel. During the sixteenth century a wealth of material on children’s play and deportment emerged in the form of humanist school colloquies and treatises. A number of these were closely related to the education system in Antwerp and were penned by members of Bruegel’s circle of associates. These have never been brought to bear on Children’s Games, and are used in chapter 3 to develop a new, historically-accurate reading of the painting. The pedagogical texts suggest that during the sixteenth century children’s play was viewed positively and was closely bound to education, and so challenge the canonical view arising chiefly from c.17th emblem books and paintings that Children’s Games makes moral points about adult behaviour. Appendix 1 - Enumerates Bruegel’s games and records comparable depictions found in manuscripts, printed images and paintings from the fifteenth, sixteenth and seventeenth centuries. Appendix 2 - Presents versions of Gargantua’s game-list from original editions of Rabelais’s text alongside standard translations and modern critical editions.

The goal of this record of study is to examine the major facets involved in managing several petroleum service projects located in three different countries in the Gulf of Guinea simultaneously, while effectively engaging in business development activities for the Oil and Industrial Services Group (OIS). This work also furnishes adequate background on related subject matters to enable understanding of the projects presented. The petroleum services sector is the back bone of the oil and gas industry. Services companies are vital to the success of all petroleum and energy producers in the USA, the Gulf of Guinea and the world. There is a need and demand for these service companies because they play various roles such as logistics, drilling, construction, dredging, pipe laying, procurement, food supply, human resource supply, etc. The Gulf of Guinea comprises of countries from west and central Africa. This project was limited to Nigeria, Equatorial Guinea and Cameroon. This area holds the largest petroleum reserves in Africa and plays a vital role in the global supply of petroleum. The Oil and Industrial Services Group (OIS), plans to establish herself as one of the leading petroleum service companies in this gulf. To manage this expansion, I have taken the role of Gulf of Guinea manager to apply my background as a petroleum engineer as well as my business skills to build a successful division of the company. This work provides a record of study of the management of services, projects and contracts carried out by the OIS group in the gulf of Guinea. The following are the specific projects in the Gulf of Guinea that I participated in: Managing delivering, maintenance and marketing of offshore vessels, Offshore pipe laying project, Integrated pipeline maintenance project, Development a petroleum technical training facilities, Agbami pipe insulation project, Engineering lift project and Capital budgeting analysis for potential investments. The details of the specific tasks of the job, including objectives, description, managerial role, nontechnical aspects, approaches, information sources, discussions and contributions are projected in the body of this literature.
