Role of the entrepreneur in a distinct role of profit.

A new motion illusion is discussed in relation to the idea of vision as a Grand Illusion. An experiment shows that this 'Tinkerbell effect' is a good example of a visual illusion supported by low-level stimulus information, but resulting from integration principles probably necessary for normal perception.

Increasing complexities facing physicians negotiating the bedside decision continue to fuel the debate over who is the appropriate party to offer ethics consults, should one be needed, during the decision-making process. Some very good arguments have been put forth on behalf of clinical ethicists as being the proper and best party to engage in ethics consultations. However, serious questions remain about the role of the clinical ethicist and his ability to provide the necessary level of objectivity called for in an (...) ethics consult.I argue that the clinician's professional psyche, or mode of thinking as a professional, leaves him little room to maneuver as an objective and detached third party ethics consultant. Several factors are cited and discussed that greatly influence the analyses applied to a case problem by physicians. The most formidable of these factors are habits and the practice of defensive medicine. I conclude that clinical ethicists are less suited for the overall tasks required of an objective consultant in medical cases that appear to involve insurmountable ethical issues. (shrink)

The mid-1880s, like the mid-1870s, were a time of considerable turmoil for American workers. Unemployment and wage cuts were widespread and workers responded with strikes, boycotts, union organizing, local labor tickets, and a bewildering variety of reform schemes and ideologies. Perhaps the central event of the 1880s was the Haymarket incident. The bomb and subsequent trial had a broad historical impact, sparking a red scare, blunting the eight-hour movement, establishing the stereotype of anarchists as wildeyed, foreign bombthrowers, and intensifying calls (...) for immigration restriction.

Corporate social policy can be viewed as three legs of a tripod: efficient production, stable employment, and a social and political environment that promotes high performance of both workers and managers.Social policy process consists of achieving a balance of corporate interest with other interests in the society. Each policy position taken by the firm alters its relationships with all other interests and creates a new balance. This entails the risk of creating unfriendly interests and losing the support of others, depending (...) on the issue and shift in power. (shrink)

The major tenets of the recent hypothesis of punctuated equilibrium are explicit in Darwin's writing. His notes from 1837–1838 contain references to stasis and rapid change. In the first edition of the Origin (1859), Darwin described the importance of isolation of local varieties in the process of speciation. His views on the tempo of speciation were influenced by Hugh Falconer and also, perhaps, by Edward Suess (1831–1914). It is paradoxical that, although both topics were recorded in his unpublished notes of (...) 1837–1838, the second was not explicitly and fully discussed until the fourth edition of the Origin (1866). While no wholly satisfactory explanation of this paradox suggests itself, it seems probable that Falconer's work on the persistence of fossil species of elephant helped Darwin to see the wider significance of the tempo of evolution for his general theory.

The temporal granularity of consciousness may be far less fine than the real-time information processing mechanisms that underlie our sensitivity to small temporal differences. It is suggested that conscious time perception, like space perception, is subject to errors that belie a unitary underlying representation. E. R. Clay's concept of the “specious present,” an extended moment represented in consciousness, is suggested as an alternative to the more common notion of instantaneous experience that underlies much reasoning based on the “time of arrival” (...) in consciousness.

This thesis maintains that Friedrich Holderlin's poetic thought is a key element not only in the development of Martin Heidegger's philosophical thought from 1929/30 to 1933 but also in his decision to become politically involved with National Socialism. Although Heidegger was familiar with Holderlin's poetry prior to 1929, he did not perceive the significance of the poet's thought and language until he was able to overcome the position of transcendental subjectivity which haunts Being and Time. Heidegger did so in 1929/30 (...) by shattering the unity of Dasein's temporal horizon--a unity which still preserved the assumption of being as permanent presence. This enabled Heidegger to think through the turn or Kehre to the occurrence of being as difference as the originary event which gave rise not only to Greek philosophy but the Western tradition as a whole. ;It is precisely at this juncture that Holderlin's poetic thought and language became significant for Heidegger. The turn from the unity of Dasein's temporality to the occurrence of being as time implies not only a revolution in thinking but also a revolution in language. Heidegger's attempt to set this revolution in motion by setting the originary sense of the Greek logos to work linguistically in his own work is the philosophical counterpart of what Norbert von Hellingrath first described as Holderlin's harte Fugung or hard style. ;The pre-logical grammar and syntax Heidegger employed, I have called the language of revolution. Its purpose is to dislocate thinking out of metaphysics toward a hidden Greek origin in the past which shows itself in the future as what is left unthought of the Greek beginning and what still remains to be thought. This back-and-forth movement of questioning is the philosophical counterpart to Holderlin's poetic andenken. In dislocating political and ideological thought from its metaphysical foundations, Heidegger intended to shift the political revolution, especially in the universities, toward a second, deeper revolution which would confront the hidden origin of the Western tradition itself.
