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.

One of the most successful methods for discovering the way mental processes are organized is to observe the effects in experiments of selectively influencing the processes. Selective influence is crucial in techniques such as Sternberg's additive factor method for reaction times and Jacoby's process dissociation procedure for accuracy. The successful uses of selective influence have encouraged application extensions to complex architectures, to dependent variables such as evoked potentials, and to complex interpretations. But the common themes have become lost in the details of separate uses and specialized terminology. The book gives an introductory and unified account of the many uses of the technique in cognitive psychology. Related models from operations research and human factors are covered. The applications include dual tasks, visual and memory search, timing, categorization, and recall. The book takes a self-contained approach starting with clear explanations of the elementary notions and a building to advanced techniques. The book is written with graduate students in mind, but has content of interest to all researchers in cognitive science and cognitive engineering.

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>
