Our understanding of communication and its evolution has advanced significantly through the study of simple models involving interacting senders and receivers of signals. Many theorists have thought that the resources of mathematical information theory are all that are needed to capture the meaning or content that is being communicated in these systems. However, the way theorists routinely talk about the models implicitly draws on a conception of content that is richer than bare informational content, especially in contexts where false content (...) is important. This article shows that this concept can be made precise by defining a notion of functional content that captures the degree to which different states of the world are involved in stabilizing senders’ and receivers’ use of a signal at equilibrium. A series of case studies is used to contrast functional content with informational content, and to illustrate the explanatory role and limitations of this definition of functional content. _1_ Introduction _2_ Modelling Framework _3_ Two Kinds of Content _3.1_ Informational content _3.2_ Functional content _4_ Cases _4.1_ Case 1: Simplest case _4.2_ Case 2: Partial pooling _4.3_ Case 3: Bottleneck _4.4_ Case 4: Partial common interest _4.5_ Case 5: Deception _4.6_ Case 6: A further problem arising from divergent interests _5_ Discussion Appendix.

This article aims to show that Sophocles anticipates questions about the autonomous subject and “ownership” of the self that are central to contemporary discourse. It suggests that Sophoclean self-killing, often considered quintessentially individualistic, in fact reflects a preoccupation with the autocheir, a less definite figure than our “suicide,” since s/he may also be a kin-killer. Also, that where Sophocles attempts to distinguish self-killing from kin-killing, it is to isolate and explore the nature and implications of autocheiria. Close readings of scenes (...) from Antigone, Ajax, and Trachiniae demonstrate that this is achieved through the elision or obscuring of the moment of self-destruction, and the posthumous analysis of self-killing in the “verbal post-mortem.” A strand of metacriticism suggests that editors committed to a model of suicide as unequivocal act intentionally performed by a single agent have sometimes oversimplified the complexity evidenced by the transmitted text.

Individual differences in ethical ideology are believed to play a key role in ethical decision making. Forsyths (1980) Ethics Position Questionnaire (EPQ) is designed to measure ethical ideology along two dimensions, relativism and idealism. This study extends the work of Forsyth by examining the construct validity of the EPQ. Confirmatory factor analyses conducted with independent samples indicated three factors – idealism, relativism, and veracity – account for the relationships among EPQ items. In order to provide further evidence of the instruments (...) nomological and convergent validity, correlations among the EPQ subscales, dogmatism, empathy, and individual differences in the use of moral rationales were examined. The relationship between EPQ measures of idealism and moral judgments demonstrated modest predictive validity, but the appreciably weaker influence of relativism and the emergence of a veracity factor raise questions about the utility of the EPQ typology.
