This paper proposes an ecological approach to the perception and interpretation of signs. The theory draws upon the ecological approach of James Gibson . It is proposed that cultural and natural perception can both be explained in terms of the direct pick-up of structured information and the Gibsonian concept of affordances without having to invoke a sharp distinction between direct and indirect perception. The application of the theory is exemplified through attention to language and to the visual and audio arts.

As militarization of bodies politic continues apace the world over, as military organizations again reveal themselves as primary political, economic and cultural forces in many societies, we argue that the emergent and potentially dominant form of political economic organization is a species of neo-feudal corporatism. Drawing upon Bourdieu, we theorize bodies politic as living habitus. Bodies politic are prepared for war and peace through new mediations, powerful means of public pedagogy. The process of militarization requires the generation of new, antagonistic (...) evaluations of other bodies politic. Such evaluations are inculcated via these mediations, the movement of meanings across time and space, between formerly disparate histories, places, and cultures. New mediations touch new and different aspects of the body politic: its eyes, its ears, its organs, but they are consistently targeted at the formation of dispositions, the prime movers of action.

A collection of essays by Timothy W. Luke discussing social and political issues related to ecology, environmentalism, ecocriticism, global climate change, and the Anthropocene.

In the absence of explicit punitive sanctions, why do individuals voluntarily participate in intergroup warfare when doing so incurs a mortality risk? Here we consider the motivation of individuals for participating in warfare. We hypothesize that in addition to other considerations, individuals are incentivized by the possibility of rewards. We test a prediction of this “cultural rewards war-risk hypothesis” with ethnographic literature on warfare in small-scale societies. We find that a greater number of benefits from warfare is associated with a (...) higher rate of death from conflict. This provides preliminary support for the relationship between rewards and participation in warfare. (shrink)

The injunction to “analyze the way you randomize” is well known to statisticians since Fisher advocated for randomization as the basis of inference. Yet even those convinced by the merits of randomization-based inference seldom follow this injunction to the letter. Bernoulli randomized experiments are often analyzed as completely randomized experiments, and completely randomized experiments are analyzed as if they had been stratified; more generally, it is not uncommon to analyze an experiment as if it had been randomized differently. This article (...) examines the theoretical foundation behind this practice within a randomization-based framework. Specifically, we ask when is it legitimate to analyze an experiment randomized according to one design as if it had been randomized according to some other design. We show that a sufficient condition for this type of analysis to be valid is that the design used for analysis should be derived from the original design by an appropriate form of conditioning. We use our theory to justify certain existing methods, question others, and finally suggest new methodological insights such as conditioning on approximate covariate balance. (shrink)

This study reassesses the concept of the Anthropocene as a new geological age as it is influencing contemporary debates in social theory. As a unit of geological time whose changes are allegedly caused, directly and indirectly, by human beings, this scientific concept challenges the existing constructions of theoretical binaries, such as nature/culture, environment/society, objectivity/subjectivity or happenstance/design, in social theory. The analysis suggests many understandings of the Anthropocene in social theory are politicized over-interpretations of natural events, and these moves appear to (...) be developing moral rhetorics of, and operational plans for, managing the Anthropocene to create specific outcomes for those who are the managers as well as the managed. The fact that human beings do not, in fact, have this measure of technical control is ignored by advocates of Anthropocenarian politics to advance their policy agendas. (shrink)

Chimpanzee and hunter-gatherer intergroup aggression differ in important ways, including humans having the ability to form peaceful relationships and alliances among groups. This paper nevertheless evaluates the hypothesis that intergroup aggression evolved according to the same functional principles in the two species—selection favoring a tendency to kill members of neighboring groups when killing could be carried out safely. According to this idea chimpanzees and humans are equally risk-averse when fighting. When self-sacrificial war practices are found in humans, therefore, they result (...) from cultural systems of reward, punishment, and coercion rather than evolved adaptations to greater risk-taking. To test this “chimpanzee model,” we review intergroup fighting in chimpanzees and nomadic hunter-gatherers living with other nomadic hunter-gatherers as neighbors. Whether humans have evolved specific psychological adaptations for war is unknown, but current evidence suggests that the chimpanzee model is an appropriate starting point for analyzing the biological and cultural evolution of warfare.

ExcerptWhat is “the place of truth at the university”? This is more than a metaphysical question. To address it, this analysis first considers broader facets of this question and then examines more specific qualities in the concern with truth by focusing on how particular universities in the United States situate themselves with respect to this issue. Only by considering their everyday operations, as the contemporary creators and curators of the truths they tout in their workings today, can a more concrete (...) critical sense of this question be crafted.
