Researchers typically define animal signaling as morphology or behavior specialized for transmitting encoded information from a signaler to a perceiver. Although intuitively appealing, this conception is inherently metaphorical and leaves concepts of both information and encoding undefined. To justify relying on the information construct, theorists often appeal to Shannon and Weaver’s quantitative definition. The two approaches are, however, fundamentally at odds. The predominant definition of animal signaling is thus untenable, which has a number of undesirable consequences for both theory and (...) practice in the field. Theoretical problems include conceptual circularity and running afoul of fundamental evolutionary principles. Problems in empirical work include that research is often grounded in abstractions such as signal honesty and semanticity, and thereby distracted from more basic and concrete factors shaping communication. A revised definition is therefore proposed, making influence rather than transmission of encoded information the central function of animal signaling. This definition is conceptually sound, empirically testable, and inclusive, yet bounded. Implications are considered in both theoretical and empirical domains. (shrink)

Michael Ryan's Literary Theory: A Practical Introduction, Second Edition introduces students to the full range of contemporary approaches to the study of literature and culture, from Formalism, Structuralism, and Historicism to Ethnic Studies, Gender Studies, and Global English. Introduces readings from a variety of theoretical perspectives, on classic literary texts. Demonstrates how the varying perspectives on texts can lead to different interpretations of the same work. Contains an accessible account of different theoretical approaches An ideal resource for use in introductory (...) courses on literary theory and criticism. Designed to function both as a stand-alone text and a companion to Rivkin and Ryan’s Literary Theory: An Anthology, Second Edition. (shrink)
_ Americans were forced to decide during an 18-month period of intense uncertainty whether to invade Iraq as part of the war against terrorism. This article reports compelling evidence that mainstream media between September 2001 and March 2003 failed in their primary responsibility: to provide sound news and commentary on which Americans could base critical decisions about war and peace. One reason is that journalists did not use an objective approach-in part because it had been discredited by media professionals and (...) critics who advocated more activist approaches. (shrink)
This anthology of classic and cutting-edge statements in literary theory has now been updated to include recent influential texts in the areas of Ethnic Studies, Postcolonialism and International Studies. A definitive collection of classic statements in criticism and new theoretical work from the past few decades. All the major schools and methods that make up the dynamic field of literary theory are represented, from Formalism to Postcolonialism. Enables students to familiarise themselves with the most recent developments in literary theory and (...) with the traditions from which these new theories derive. (shrink)
Objective journalism is blamed frequently for all sorts of journalistic failures and weaknesses, but the critiques typically are flawed because their authors fail to understand objectivity or to define it precisely. This defense of objective journalism defines objectivity and suggests that it is indispensable in a free society, summarizes major critiques of and alternatives to objectivity, and proposes that critics and defenders might serve journalism best by seeking common ground.

We consider Sussman et al.'s suggestion that auditory biases for processing low-noise relationships among pairs of acoustic variables is a preadaptation for human speech processing. Data from other animal communication systems, especially those involving sexual selection, also suggest that neural biases in the receiver system can generate strong selection on the form of communication signals.
Observers call for companies to establish codes of corporate social responsibility, but few have studied how companies become aware of and codify standards. This study of the practitioner's role in developing standards suggests that practitioners often are left out of ethical decision making, and that persons who prepare codes of ethical performance typically view external publics as less important than internal publics. Social science methods are widely recognized as helpful in identifying and establishing standards, although they are not actually used (...) very much. (shrink)
