Conventionality and aptness are two dimensions of metaphorical sentences thought to play an important role in determining how quick and easy it is to process a metaphor. Conventionality reflects the familiarity of a metaphor whereas aptness reflects the degree to which a metaphor vehicle captures important features of a metaphor topic. In recent years it has become clear that operationalizing these two constructs is not as simple as asking naïve raters for subjective judgments. It has been found that ratings of (...) aptness and conventionality are highly correlated, which has led some researchers to pursue alternative methods for measuring the constructs. Here, in four experiments, we explore the underlying reasons for the high correlation in ratings of aptness and conventionality, and question the construct validity of various methods for measuring the two dimensions. We find that manipulating the processing fluency of a metaphorical sentence by means of familiarization to similar senses of the metaphor (“in vivo conventionalization”) influences ratings of the sentence's aptness. This misattribution may help explain why subjective ratings of aptness and conventionality are highly correlated. In addition, we find other reasons to question the construct validity of conventionality and aptness measures: for instance, we find that conventionality is context dependent and thus not attributable to a metaphor vehicle alone, and we find that ratings of aptness take more into account than they should.

Role of the entrepreneur in a distinct role of profit.

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 It is paradoxical that, although both topics were recorded in his unpublished notes of (...) 1837–1838, the second was not explicitly and fully discussed until the fourth edition of the Origin (1866).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.

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)

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)

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.

There are problems with both the theoretical logic and the interpretation of data in Christie and Barresi's interesting article. The general pattern of results is easily incorporated into an information-processing framework compatible with Dennett's analysis. In particular, different aspects of the illusory motion event are queried at different times and these aspects are not in conflict, so no revision of conscious content is necessary. Second, too much interpretive weight is placed on an anomalous pair of data points that do not (...) seem fully interpretable within the author's framework and are probably susceptible to one of several alternative interpretations proposed here, though further investigation is necessary.

Although Pessoa et al. imply that many aspects of the filling-in debate may be displaced by a regard for active vision, they remain loyal to naive neural reductionist explanations of certain pieces of psychophysical evidence. Alternative interpretations are provided for two specific examples and a new category of filling-in (of visual detail) is proposed.

Medicine and Money explores the role of beneficence and cost control in health-care systems. The book's primary concern of morally improving medicine is achieved by dividing the argument into two parts. The first defines the crisis in health-care and justifies beneficence. The second part offers practical suggestions on implementing beneficence into the system. Medicine and Money is one of the few books to provide concrete suggestions on improving the health-care system from the micro level for addressing cost concerns in a (...) morally acceptable manner.

From Heidegger's letters to Elisabeth Blochmann in 1932, it is apparent that he is on the verge of crossing the Rubicon into the political arena. On December 19, 1932, Heidegger tells her.

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.
