Many physicists regard the flow of time as an illusion. There is an upper level flow of time, the phenomenon of past/present/future; and there is a lower level flow of time which is really a flow of events. Perceptual completion accounts for the lower level flow of time in a few ways: apparent movement; amodal completion; and dynamic change as exemplified by a newly described modal completion that we called happening. It acts like an illusory percept connecting discrete stimuli in (...) all sensory modalities. The past/present/future distinction cannot exist unless an object is perceived to be the same now as it is then. This cognition requires object persistence. Experiments with object persistence suggest the circumstances when that, too, is an illusory percept. The illusory percepts of object persistence and perceptual completion can account for the entire flow of time. Our findings and conclusions are congruent with a few time theories and cosmologies that suggest that the flow of time is an illusion. (shrink)

Understanding of organizational ethics phenomena requires complex understanding of organizational practices in their real world contexts. We can try to understand and build theory about these complex real world practices from the points of view of: a traditional deductive, ethics literature-based, literature gap formulation approach; or, an inductive, practitioner-based literature gap formulation approach. This consideration of inductive, practitioner-based versus deductive, literature-based literature gap formulation is related to the discussion concerning “engaged scholarship” and relationships and gaps between theory and practice in (...) organization studies [Van De Ven, 2007, Engaged Scholarship: A Guide for Organizational and Research Knowledge ]. However, there is an important difference with respect to the key issue of ethics literature versus practitioner-based literature gap formulation. This article offers examples of the two different approaches and makes comparisons between them. Implications for practice-based organizational ethics theory building, Ph.D. education, and public intellectual work are considered. (shrink)

We discuss five kinds of representations of rationales and provide a formal account of how they can alter disputation. The formal model of disputation is derived from recent work in argument. The five kinds of rationales are compilation rationales, which can be represented without assuming domain-knowledge (such as utilities) beyond that normally required for argument. The principal thesis is that such rationales can be analyzed in a framework of argument not too different from what AI already has. The result is (...) a formal understanding of rationales, a partial taxonomy, and a foundation for computer programs that represent and reason with rationales.The five kinds of rationales are as follows: (c)ompression and (s)pecialization, which yield rules, and (d)isputation, which yields a decision. These are modeled as potentially changing the focus of the dispute. Then there are (f)it, a rationale for rules, and (r)esolution, a rationale for decisions. These cannot be modeled as simply; they force disputation to a meta-level, at least temporarily. (shrink)

Dynamic intra-individual variability (IIV) in cardiac vagal control across multiple situations is believed to contribute to adaptive cognition under stress; however, a dearth of research has empirically tested this notion. To this end, we examined 25 U.S. Army Soldiers (all male, Mean Age= 30.73, SD = 7.71) whose high-frequency heart rate variability (HF-HRV) was measured during a resting baseline and during three conditions of a shooting task (training, low stress, high stress). Response inhibition was measured as the correct rejection of (...) friendly targets during the low and high stress conditions. We tested the association between the standard deviation of HF-HRV across all four task conditions (IIV in vagal control) and changes in response inhibition between low and high stress. Greater differences in vagal control between conditions (larger IIV) were associated with higher tonic vagal control during rest, and stronger stress-related decreases in response inhibition. These results suggest that flexibility in vagal control is supported by tonic vagal control, but this flexibility also uniquely relates to adaptive cognition under stress. Findings are consistent with neurobehavioral and dynamical systems theories of vagal function. (shrink)

This paper analyzes the basic issues and concepts concerning the knowledge-centered tradition of Indian philosophical quest. As a matter of fact, the present millennium is different from all other such epochs of human history. There is a strong impression that we have failed in making use of 'information' and 'knowledge' hidden in ancient scriptures for the benefit of humanity. It is in this context that knowledge-centered tradition in the Indian philosophy can be of immense help. This kind of study can (...) properly be done in the light of the intellectual traditions of the Western thinkers along with globalization and postmodern developments. (shrink)

The disappearance of the imperial biographies written by Marius Maximus is one of the more frustrating losses of Latin literature, for various reasons: the well-known testimony of Ammianus, the interest of Marius Maximus' attested contribution to the Historia Augusta, his importance, much in dispute, to the writer of that work, the lack of information on much of the period he covered, and, not least, the fascinating role assigned to him by modern scholars, remodelling a previous duality of sources, of bad (...) biographer in contrast to the good Ignotus. It has recently become common practice for the evidence of Ausonius' Caesares to be used in the search for this biographer. The suggestion goes back to a dissertation of F. della Corte in 1956/7, and was taken up in his edition of Ausonius' works by Pastorino, and discussed in the following year by Cazzaniga who, though uncertain about the dependence of Ausonius on Marius Maximus, does misleadingly assert ‘e certo che l'ultima epigramma tocca Elagabalo, che chiude la silloge’. More recently, della Corte has returned to the question and sketched a possible model for the growth of the whole extant collection of Ausonius' Caesares, on the basis of the manuscript tradition. The same volume contains a contribution to the question by S. d'Elia and includes, by a felicitous piece of editing, an extended footnote in which d'Elia is able to comment on the relevant part of della Corte's paper. Meanwhile, outside Italy, there have been parallel and independent developments. (shrink)

I propose that neural cognition is supported by non-neural storage of a 3-D model of local space, used in the planning of movements. Information is stored in wave-like excitations which couple to neurons in the thalamus, with the wave-vectors of excitations representing spatial positions. This hybrid of neural and non-neural cognition may have fitness advantages over any purely neural mechanism -- in information capacity, geometric accuracy, and fast selective retrieval. The wave excitations may be sustained on a Bose-condensed state of (...) some excitation in the brain, by a mechanism like those investigated by Frohlich, Umezawa, Vitiello and others. These states, being frictionless, can store information indefinitely at low energy levels, insulated from thermal noise, so are an ideal substrate for memory. If a Bose-condensed state is a 3-D representation of local reality, it may be the basis of phenomenal consciousness . The resulting theory of consciousness is highly constrained, and agrees well with the main properties of conscious experience. In this account, consciousness arises from a very simple state of matter, rather than from complexity; and it evolved to meet one of the strongest selection pressures on the brain. (shrink)

To whom do sperm and ova belong? Few tissues are produced by the human body with more waste than the germ cells. Yet dominion over the germ cells, and over the early embryo that results from their union in vitro, is behind much of the emotion that modern reproductive intervention can engender. The germ cells differ from other human tissues that can be donated or transplanted because they carry readily utilizable genetic information. Eventual expression of the germ cells' genetic potential (...) is the legitimate concern and responsibility of their donors, although in the right circumstances the responsibility can by agreement be entrusted to institutions administering gamete or embryo donor programmes; these institutions, in turn, may need to assume responsibility for decisions if, in the case of embryo storage, the wishes of the two donors conflict. The fact of sperm and ovum ownership (and the genetic potential that goes with it) before individuals part with these tissues is beyond dispute. Some contentious issues may be clarified if this area of human dominion, namely control over genetic expression among offspring, is acknowledged to be the legitimate persisting concern of those who have produced sperm and ova after storage commences.
