This brief introduces overlapping coalition formation games (OCF games), a novel mathematical framework from cooperative game theory that can be used to model, design and analyze cooperative scenarios in future wireless communication networks. The concepts of OCF games are explained, and several algorithmic aspects are studied. In addition, several major application scenarios are discussed. These applications are drawn from a variety of fields that include radio resource allocation in dense wireless networks, cooperative spectrum sensing for cognitive radio networks, and resource management for crowd sourcing. For each application, the use of OCF games is discussed in detail in order to show how this framework can be used to solve relevant wireless networking problems. Overlapping Coalition Formation Games in Wireless Communication Networks provides researchers, students and practitioners with a concise overview of existing works in this emerging area, exploring the relevant fundamental theories, key techniques, and significant applications.
We study the impact of foreign institutional investors on global capital allocation and welfare using novel firm-level international data. Using MSCI index inclusion as an exogenous shock to foreign ownership, we show that greater foreign ownership leads to more informative stock prices and this effect arises more from increased price efficiency than from improved firm governance. We further show that the impact of capital flows on price efficiency is due to real efficiency gains, as opposed to better information disclosure. Finally, we show that foreign ownership increases market liquidity, reduces firms' cost of equity, and leads to subsequent growth in their real investments, thus improving overall welfare.
Es ist Allgemeinwissen: der Mensch besteht zu mehr als 70 Gewichtsprozent aus Wasser - Man erf?hrt dies entweder in der Natur auf Waldlehrpfaden oder in der Grundschule... Wasser ist ?berlebenswichtig und wird in einem weit verzweigten Rohleitungssystem bef?rdert: den Blut- und Lymphebahnen, vom kleinen Zeh bis in das Sprachzentrum des Hirns. Aber welche Rolle spielt Wasser in der Chemie des Menschen? Der Chemie-Professor J?rgen Fuhrhop und Dr. Tianyu Wang haben die un?bersehbare Anzahl chemischer Verbindung auf sieben Lebensmolek?le beschr?nkt. Nach ihrer Auffassung sind diese, von der Evolution auserw?hlten Molek?le die Tr?ger des menschlichen Lebens. Und die Autoren scheuen weder einen Bl...
"Metallic and Molecular Interactions in Nanometer Layers, Pores and Particles: New Findings at the Yoctolitre Level describes new developments in the nanochemistry of almost all elements of the periodic system, primarily for the years from 2006-2008." "The main benefit of this book is the actualization of the interest in the elements of the periodic system. Important qualities of ultrathin assemblies, which are not common knowledge to chemists, including magnetism, luminescence, conductivity, thermoelectricity and density functional theory are explained in an introductory chapter. Carbon yocotwells and iron nanoparticles are covered in separate chapters. Other elements are discussed, mostly in connection with interesting new nanocrystal and nanowire phenomena and the packing of molecules and atoms within yoctowells - containers with the volume of a few cubic nanometres."--BOOK JACKET.
The end of World War II led to increased interest in multicultural concerns and a flourishing of literary and artistic endeavors. It was also a time of decolonization and the emergence of new nations and cultures clamoring for recognition and respect. The political circumstances following World War II exposed many people to other cultures. This reference discusses the experiences of writers active since 1945 who were shaped by cultures other than their own. Included are alphabetically arranged entries for more than 100 writers, including Chinua Achebe, W.H. Auden, Mircea Eliade, Jamaica Kincaid, Salman Rushdie, and Elie Wiesel. The profiled authors either lived in another culture voluntarily or were wrenched from one culture into another. Each entry includes a brief biography, a discussion of multicultural themes in the writer's works, a review of criticism, and primary and secondary bibliographies. The volume closes with a selected, general bibliography. The reference demonstrates the value of multicultural experiences in the lives of writers around the world and fosters a greater appreciation of cultural diversity.
