A MULTIPROXY GEOCHEMICAL APPROACH TO UNRAVELING HYDROCARBON CHARGE HISTORY OF THE TRIASSIC SHUBLIK FORMATION OF ARCTIC ALASKA
No full textEvaluation of possible source rocks in northern Nye County, Nevada: implications for hydrocarbon exploration
No full textThe presence of oil outside of Railroad Valley, northern Nye County has sparked the interest of exploration companies in Nevada. The geology in this region is very complex and the level of petroleum exploration is low. In order to understand the distribution of oil, a complete petroleum systems analysis is required. Previous studies confirmed that the Mississippian Chainman Shale and Cretaceous to Paleocene Sheep Pass Formation, Member B are source rocks. However, a number of other possible source rocks exist in northern Nye County, but they are not confirmed because of incomplete datasets. The goal of this thesis project is to determine if effective source rocks other than the Chainman Shale and Sheep Pass Formation exist in northern Nye County. I obtained samples from outcrops and used organic geochemistry to test the hypothesis that different strata, including Paleozoic Vinini, Pogonip, Woodruff, Guilmette Formations, Pilot Shale, Ely Limestone, and Cretaceous Newark Canyon Formation have the necessary qualities to be petroleum source rocks.
This evaluation revealed source rock potential for Woodruff Formation, but none of the other analyzed candidate units met the requirements for organic matter quantity, quality, and thermal maturity in order to be called source rocks. The Devonian Woodruff Formation displayed excellent organic matter quantity, and oil-prone kerogen type, however samples appeared to be thermally immature. Additional oil - source rock correlation suggested genetic relationship between the Woodruff Formation and Chainman-derived oils from Railroad Valley. This knowledge will help to estimate the petroleum potential of northern Nye County for future exploration and development in Nevada
MARKETPLACES AS A KEY DRIVER OF GLOBAL E-COMMERCE
No full textCurrently, e-commerce is becoming a modern challenge to accelerate the development of the global economy. This requires the introduction of qualitatively new approaches to the strategic management of activities using information technology. The purpose of this article is to study the key issues, features and trends in the development of e-commerce in the context of international business digitalisation on the example of international online marketplaces.
This paper analyses the risks and benefits, distribution logistics issues for the development of e-commerce, and its positive and negative impact on trade in general. It is determined that today the pace of development of e-commerce is very fast, significantly exceeding the pace of development of traditional trade.
An important indicator of a successful e-commerce business strategy is a clear vision and implementation of the strategy of involving marketplaces in the trading strategy. A clear understanding of which marketplace best suits the needs of the business and competent implementation significantly increases the chances of making a quick profit in online trading. The article notes that the business model of marketplaces is considered to be promising, as it is beneficial for both the seller and the buyer. This paper considers the key and most well-known globally recognized marketplaces such as Amazon, eBay and Etsy, their main advantages and disadvantages, comparative characteristics of marketplaces and how to effectively integrate products into these tools, as well as the future implications of these concepts for distribution logistics in the context of e-commerce
Financial Development and Financing Constraints: International Evidence from the Structural Investment Model
No full textThe relationship between the financial,
and real sides of the economy has long been a topic of
intense interest, and debate. The author provides
microeconomic evidence that financial development aids
growth, by reducing financing constraints that would
otherwise restrict efficient firm investment. The author
estimates a structural model, based on the Euler equation
for investment, using firm-level data from forty countries.
The results show a strong negative relationship between the
extent of financial market development, and the sensitivity
of investment, to the availability of internal funds (a
proxy for financing constraints). Considering size effects,
business cycles, and the legal environment as plausible
alternative explanations, the author finds the results to be
robust in all cases

Corporate Governance and Performance around the World: What We Know and What We Don't
No full textThe author surveys a vast body of literature devoted to evaluating the relationship between corporate governance and performance as measured by valuation, operating performance, or stock returns. Most of the evidence to date suggests a positive association between corporate governance and various measures of performance. However, this line of research suffers from endogeneity problems that are difficult to resolve. There is no consensus yet on the nature of the endogeneity in governance--performance studies and in this survey the author proposes an approach to resolve it. The emerging conclusion is that corporate governance is likely to develop endogenously and depend on specific characteristics of the firm and its environment. Copyright The Author 2010.

Cluster Initiatives as Intermediaries : A Study of their Management and Stakeholders
No full textThis dissertation offers a platform to understand the nature of cluster initiatives as a socio-economic phenomenon combining cluster, entrepreneurship and intermediary features. They are particular types of ventures facilitating networks and dialog platforms adjusted to local contexts and offering a way to enhance regional development. The success of clusters and regions is shaped by the degree they are based on and involve entrepreneurial activity, which is viewed here under the prism of cluster initiatives. This dissertation uses both qualitative and quantitative approaches to study various organizational aspects of cluster initiatives and their intermediary role as well as providing recommendations for the management and support of these organizations. It is based on five papers written by the author of the dissertation solely and in collaboration with other scholars where the level of analysis is focused on cluster initiatives. Based on empirical material from the papers this dissertation brings together both the structural and organizational content of cluster initiatives by providing evidence in the areas of actors and relationships, mode of organization and intermediary specific, assessment and management as well as policy. This work has generated the following conclusions: firstly, cluster initiatives represent organizations bringing together a four-faceted constellation of interrelated actors (i.e. the initiative itself, key player, support and target group), through organization of intermediary activities. Secondly, these organizations are organized as temporary projects, but being able to attract many members and to satisfy their needs through diversified and innovative activities can help them to achieve longevity. The longevity of initiatives can also be supported by policy, which in order to become effective, should include a long-term perspective and bottom-up approach. And finally, the study proposes a model of five central qualitative success factors to be used for the assessment and management of the initiatives, which together depict a holistic picture of their functioning. This model contains elements such as idea, driving forces, activities, organization and critical mass. The two models of interrelated actors and of success factors form the main contribution of this work. Extending the stream of studies this dissertation raises awareness and calls for recognition of cluster initiatives as important actors working in-between the boundaries of other organizations and institutions.PIE/HELI
Concession contract renegotiations : some efficiency versus equity dilemmas
No full textThe authors analyze the possibility of tradeoffs between efficiency and equity as well as the possibility of distributional conflicts in the context of renegotiation of infrastructure contracts in developing countries. To do so, they present a model in which contracts are awarded by auctioning the right to operate an infrastructure service to a private monopoly, and consider the possibility of renegotiation. To identify the potential sources of tradeoffs, they trackthe possible outcomes of different renegotiation strategies for the monopoly running the concession and for the two groups of consumers-rich and poor-who alternate in power according to a majority voting rule. Among the model? most important policy implications is this: if having firm-driven renegotiations is a major concern, efficiency should not be the only consideration in selecting an operator. Indeed, consumers may want to award the concession to a less efficient firm if that would reduce the probability of renegotiation, since a lower probability of firm-driven renegotiations (due to demand shocks, for example) is associated with higher welfare for all service users.Environmental Economics&Policies,Labor Policies,Markets and Market Access,Economic Theory&Research,International Terrorism&Counterterrorism,Economic Theory&Research,Environmental Economics&Policies,Markets and Market Access,Access to Markets,International Terrorism&Counterterrorism
A Well with a Gargoyle and the Principle of Hyperquotation in the Architecture of the Livadia Palace
No full textThe article is devoted to studying the circumstances that served as the basis for the quotation of the original composition installed during the restoration of the Vincigliata Castle near Florence (1860s) in the sculpture A Well with a Gargoyle in the Livadia Palace. A comparative analysis of the copy and the original leads to the problem of hyperquotation in the work on the project of the imperial residence in the Crimea (1909–1914). For the first time, the article publishes the photographs of the historical courtyard of the Vincigliata sculptures from the State Historical Museum funds (Moscow) and the view of the Livadia well from the architect N.P. Krasnov’s author album from the funds of the Research Library under Russian Academy of Arts (Saint‐Petersburg)
