Carbon offsetting can be loosely characterized as a mechanism by which an organization or individual contributes to a scheme that is projected either to remove carbon dioxide from the atmosphere or to deliver carbon dioxide emission reductions on the part of other organizations or individuals. An activity that has been offset therefore purports to make no long-term net contribution to atmospheric greenhouse gas concentrations. The ethical basis for using carbon offsetting as an approach to tackling climate change is very much (...) contested. We seek to expose some of the underlying reasons for these ethical disagreements. We show that they relate both to empirical disagreements about what the likely benefits of offsetting are and, more fundamentally, to principled disagreements about the right way to discharge duties to deliver carbon reductions.

Due in part to a growing realization of the importance of the role that retailing plays in the marketing channel, and to the increasing numbers of college graduates being employed by retailers, growing attention is being placed on business students'' ethical perceptions of retailing practices. This study continues this focus by examining the ethical perceptions of collegiate business students attending two different universities which likely represent two different microcultures — conservative evangelical Protestant and secular.The results suggest that ethical perceptions may (...) vary between the students attending two universities which likely represent differing microcultures. The students attending the conservative evangelical Protestant university appear to possess ethical perceptions which are significantly more ethical than those of students attending the public university. Evidence was observed, therefore, which suggests that ethical perceptions may vary across students from differing microcultures. (shrink)
In an item-method directed forgetting paradigm, participants were required to attend to one of two colored words presented on opposite sides of a central fixation stimulus; they were instructed to Remember or Forget the attended item. On a subsequent recognition test, the Attended words showed a typical directed forgetting effect with better recognition of Remember words than Forget words. Our interest was in the fate of the Unattended words. When the study display disappeared before the memory instruction, there was no (...) effect of that instruction on unattended words; when the study display remained visible during presentation of the memory instruction, there was a reverse directed forgetting effect with better recognition of unattended words from Forget trials than from Remember trials. Incidental encoding of task-irrelevant stimuli occurs following presentation of a Forget instruction – but only when those task-irrelevant stimuli are still visible in the external environment.

Compact quantum systems have underlying compact kinematical Lie algebras, in contrast to familiar noncompact quantum systems built on the Weyl-Heisenberg algebra. Pauli asked in the latter case: to what extent does knowledge of the probability distributions in coordinate and momentum space determine the state vector? The analogous question for compact quantum systems is raised, and some preliminary results are obtained.
Selection on grandparental investment is more complex than Coall & Hertwig (C&H) propose. Patterns of investment are subject to an intergenerational conflict over how resources should be distributed to maximize fitness. Grandparents may be selected to distribute resources unevenly, while their descendants will be selected to manipulate investment in their own favor. Here we outline the evolutionary basis of this conflict.
This article looks at the medieval culture of reading, and suggests that medieval readership and modern reading strategies have significant points of contact including a tolerance for ambiguity, engagement with chains of intertextuality, and an embrace of the fragmentary nature of knowledge. It argues that the medieval reader was not a superstitious bumpkin, but rather a sophisticated interpreter within a complex system of signification. The medieval reader engaged in sophisticated coding, decoding, and recoding. While this article argues for similarity of (...) strategic modes of reading between the medieval scholar and modern reader, similarities should not be mistaken for equivalencies. Where the modern reader embraces intertextuality for its own sake, the medieval reader’s assumption of divine truth served as an anchor to the chain of intertextuality. This article examines Umberto Eco’s reading of Dante’s theory of language to give us insight into medieval approaches to signification, and applies those insights to St. Augustine’s Confessions. As one of the “four doctors” of the Catholic Church, Augustine served as a model of readership for many theologians to follow. St. Augustine’s practices of readership and signification would establish a practice of reading as encoding and decoding sophisticated networks of signs. (shrink)
