Mediated messages flood our daily lives, through virtually endless choices of media channels, genres, and content. However, selectivity determines what media messages we attend to and focus on. The present book examines the factors that influence this selectivity. Seminal books on selective media exposure were published in 1960 by Klapper and in 1985 by Zillmann and Bryant. But an integrated update on this research field is much needed, as rigorous selective exposure research has flourished in the new millennium. In the contexts of political communication, health communication, Internet use, entertainment consumption, and electronic games, the crucial question of how individuals choose what content they consume has garnered much attention. The present book integrates theories and empirical evidence from these domains and discusses the related research methodologies. In light of the ever-increasing abundance of media channels and messages, selective exposure has become more important than ever for media impacts. This monograph provides a comprehensive review of the research on selective exposure to media messages, which is at the heart of communication science and media effects. It is required reading for media scholars and researchers, and promises to influence and inspire future research.

This volume explores the reasons for Hans Kelsen’s lack of influence in the United States and proposes ways in which Kelsen’s approach to law, philosophy, and political, democratic, and international relations theory could be relevant to current debates within the U.S. academy in those areas. Along the way, the volume examines Kelsen’s relationship and often hidden influences on other members of the mid-century Central European émigré community whose work helped shape twentieth-century social science in the United States. The book includes major contributions to the history of ideas and to the sociology of the professions in the U.S. academy in the twentieth century. Each section of the volume explores a different aspect of the puzzle of the neglect of Kelsen’s work in various disciplinary and national settings. Part I provides reconstructions of Kelsen’s legal theory and defends that theory against negative assessments in Anglo-American jurisprudence. Part II focuses both on Kelsen’s theoretical views on international law and his practical involvement in the post-war development of international criminal law. Part III addresses Kelsen’s theories of democracy and justice while placing him in dialogue with other major twentieth-century thinkers, including two fellow émigré scholars, Leo Strauss and Albert Ehrenzweig. Part IV explores Kelsen’s intellectual legacies through European and American perspectives on the interaction of Kelsen’s theoretical approach to law and national legal traditions in the United States and Germany. Each contribution features a particular applications of Kelsen’s approach to doctrinal and interpretive issues currently of interest in the legal academy. The volume concludes with two chapters on the nature of Kelsen’s legal theory as an instance of modernism.

This thesis offers novel methods for catalyst and process design for the selective hydrogenation of acetylene and 1,3-butadiene. The author predicts the properties of supported Pd–Ni bimetallic catalysts using density functional theory (DFT) calculations and temperature-programmed desorption (TPD). The excellent correlation between model surfaces and supported catalysts demonstrates the feasibility of designing effective bimetallic catalysts for selective hydrogenation reactions. The author also proposes a method for designing non-precious metal catalysts to replace precious metals. She modifies the process of selective hydrogenation of acetylene by coupling the selective adsorption to the selective hydrogenation in the liquid phase, as a result of which the ethylene selectivity is greatly improved and heat transfer is greatly enhanced. Lastly, by analyzing the mechanism of liquid-phase hydrogenation, the author proposes a multi-stage slurry bed reactor for industrial applications.“/p>
