The sociobiology of bacteria, largely unappreciated and ignored by the microbiology research community two decades ago is now a major research area, catalyzed to a significant degree by studies of communication and cooperative behavior among the myxobacteria and in quorum sensing (QS) and biofilm formation by pseudomonads and other microbes. Recently, the topic of multicellular cooperative behaviors among bacteria has been increasingly considered in the context of evolutionary biology. Here we discuss the significance of two recent studies1,2 of the phenomenon (...) of “cheating” mutants and their exploitation of cooperating microbial populations of Pseudomonas aeruginosa.

In a recent Article Carla Kary attempts to show that there should be a significant moral difference between instances of killing and letting die. I shall maintain in Section I that Kary's argument is somewhat weakened by the failure to note an important ambiguity in the notion of killing a person. I shall also argue in Section II that a similar ambiguity affects the notion of letting someone die, and that the failure to note this latter ambiguity also weakens the (...) position developed by Robert Coburn with regard to defective newborns.

Management plays an important role in reinforcing ethics in organizations. To support this aim, managers must use incentive and goal programs in ethical ways. This study examines experimentally the potential ethical costs associated with incentive-driven and goal-induced employee behavior from a managerial perspective. In a quasi-experimental setting, 243 MBA students with significant professional work experience evaluated a hypothetical employee’s ethical behavior under incentive pay systems modeled on a business case. In the role of the employee’s manager, participants evaluated the ethicality (...) of the employee’s incentive-driven and goal-induced ethical/unethical behavior and the outcomes of behavior, with consequences that were either favorable or unfavorable to the organization. The results indicated that participants discounted the ethical considerations of incentive-driven and goal-induced behavior when consequences were favorable to the organization. Participants’ morals and outcome orientations were also significantly related to their ethical judgments and intentions to intervene. The implications of these findings for research and practice are discussed. (shrink)

Pickering & Garrod (P&G) consider the possibility that inner speech might be a product of forward production models. Here I consider the idea of inner speech as a forward model in light of empirical work from the past few decades, concluding that, while forward models could contribute to it, inner speech nonetheless requires activity from the implementers.

In lieu of an abstract, here is a brief excerpt of the content:RANSOM'S GOD WITHOUT THUNDER: REMYTHOLOGIZING VIOLENCE AND POETICIZING THE SACRED Gary M. Ciuba Kent State University From tree-lined Vanderbilt University of 1930 Nashville, the modernist poet and critic John Crowe Ransom longed to hear in his imagination the God who thundered fiercely in ancient Greece, Rome, and Israel. The God of sacrifice who in Homer's Iliad, "his thunder striking terror," received libations from the warring armies (230). The (...) God of jealousy who in Aeschylus' Prometheus Bound "drove the sleepless thunderbolt, / plunged the fire spurting shaft/ down" on Typhon for defying heaven with his violence (46). The God of vengeance who in Ovid's Metamorphoses sent "blinding / Thunder [to shake] Olympus, and Pelim / Thrust down by heaven's bolt crashed over Ossa" when the giants piled mountain upon mountain to reach Jove's throne (35). The God ofviolence who in Psalm 78:48 delivered the cattle ofthe obstinate Egyptians "to the hail, and their flocks to hot thunderbolts" or who in 1 Samuel 7:10 "thundered with great thunder" to smite the Philistines. In God Without Thunder: An Unorthodox Defense of Orthodoxy Ransom attacked the modern heresy that deprived the deity ofsuch awful might and summoned Americans to live under a new myth of sacred violence. IfRansom listened with the ears ofthe Methodist faith in which he had been raised, he might have heard how the god of old was muted at the university where he studied and later taught. Ten years before Ransom was born, Methodist-sponsored Vanderbilt had eliminated the lectureship of naturalist Alexander Winched because hisPre-Adamites had challenged the Creation story in Genesis. But in 1914, when Ransom returned to his alma Gary M. Ciuba41 mater to begin more than two decades of teaching there, the Methodists ended their affiliation with Vanderbilt because of a dispute about church governance of the university (Bailey 9-10, 31-4). When the Scopes Trial caused a furor in 1925, Ransom was invited by Vanderbilt to condemn the Fundamentalists to the southeast in Dayton. He refused-not because he sided with the anti-Darwinists but because he believed that the tyranny of science was threateningthe poetic foundation ofreligion (Quinlan 40, n. 3). Ransom's thunderless plight was virtually imagined by H.L. Mencken, one of the most stinging critics of the creationists, when in 1922 he penned a tongue-in-cheek lament forthe passing ofthe ancient deities. "Where is the graveyard of dead gods? What lingering mourner waters their mounds? There was a time when Jupiter was the king ofthe gods, and any man who doubted his puissance was ipso facto a barbarian and an ignoramus," Mencken mock-elegized in "Memorial Service." "But where in all the world is there a man who worships Jupiter today?" (95). God Without Thunder provides the answer to Mencken's archly lugubrious question: it is John Crowe Ransom. Grieving the demise ofthe deity ofyore, Ransom's treatise on the religious imagination heralds a one-man revival of Jupiter Tonans. Ransom believes that the god ofantiquity has been muffled bythe spirit of scientific abstraction that reigns notjust in Tennessee but across all of America.7 Hetraces this modern cult ofthe mind beyond the current efforts ofreligion to seek a rapprochement with biology and physics; beyond the science-driven Prometheus of Shelley, the rationalism of the Protestant Reformation, and the inquiry of Copernicus; beyond the errors of early Christianity, to a kind of primal sin. Humans have used their intelligence first to set themselves above nature, then to order the world according to their ways, and finally to exploit all ofcreation for their use. Demystified by science, thunder has become not the mighty weapon ofthe ancient God who tolerated no rivals but only the noise of heated and expanding air. Ransom views science as having such ultimacy that it exercises a mimetic function: it provides Girardian models for desire. "Science directs us to amuse ourselves, between desires," Ransom writes, "by simulating 7 Louis Rubin reads Ransom's "Armageddon" as a poetic companion piece to God Without Thunder, for it tells how divine wrath has been compromised amid the suavities of the modern world At the apocalyptic battle of the poem's title, a militant...

This paper uses the notion of Galois-connection to examine the relation between valuation-spaces and logics. Every valuation-space gives rise to a logic, and every logic gives rise to a valuation space, where the resulting pair of functions form a Galois-connection, and the composite functions are closure-operators. A valuation-space (resp., logic) is said to be complete precisely if it is Galois-closed. Two theorems are proven. A logic is complete if and only if it is reflexive and transitive. A valuation-space is complete (...) if and only if it is closed under formation of super-valuations. (shrink)
