DennisGabor devised a new concept for optical imaging in 1947 that went by a variety of names over the following decade: holoscopy, wavefront reconstruction, interference microscopy, diffraction microscopy and Gaboroscopy. A well-connected and creative research engineer, Gabor worked actively to publicize and exploit his concept, but the scheme failed to capture the interest of many researchers. Gabor’s theory was repeatedly deemed unintuitive and baffling; the technique was appraised by his contemporaries to be of dubious practicality (...) and, at best, constrained to a narrow branch of science. By the late 1950s, Gabor’s subject had been assessed by its handful of practitioners to be a white elephant. Nevertheless, the concept was later rehabilitated by the research of Emmett Leith and Juris Upatnieks at the University of Michigan, and Yury Denisyuk at the Vavilov Institute in Leningrad. What had been judged a failure was recast as a success: evaluations of Gabor’s work were transformed during the 1960s, when it was represented as the foundation on which to construct the new and distinctly different subject of holography, a re-evaluation that gained the Nobel Prize for Physics for Gabor alone in 1971. This paper focuses on the difficulties experienced in constructing a meaningful subject, a practical application and a viable technical community from Gabor’s ideas during the decade 1947-1957.

Having established her pluralistic account as an influential position within contemporary virtue ethics, in this work Christine Swanton offers a virtue-ethical reading of David Hume and Friedrich Nietzsche with the aim of showing how they can further the development of virtue ethics beyond the Aristotelian and ancient eudaemonist traditions. Readers of Swanton’s other major work, Virtue Ethics: A Pluralistic View, may recall that many of its philosophical resources were drawn from Nietzsche and, to a lesser extent, from Hume. This new (...) study can be seen as offering a fuller and more historically grounded reading of the work of both thinkers. Swanton has also published on... (shrink)
Lawrence J. Dennis’s intellectual biography of John L. Childs, a leading figure in twentieth-century American educational philosophy between 1930 and 1960, traces Childs’s influence not only on education but also on midcentury politics, economics, and social issues. A disciple of John Dewey and an associate of William Heard Kilpatrick, George S. Counts, Boyd Bode, and other key figures in modern American education, Childs laid the philosophic basis for social reconstruction and became an important contributor to and interpreter of pragmatism (...) as a philosophy of education. Dennis describes how the Christian beliefs so central to Childs as a youth led him as a young man into a decade of YMCA missionary work in China. When he returned to the United States, Childs studied with John Dewey, later coauthoring two chapters of a book with him. Though Childs became a recognized expert on Dewey’s educational theory, he eventually became more of a reconstructionist than his mentor. Dennis carefully recounts Childs’s long association with Dewey as well as his political activities in the American Labor Party, the Liberal Party, and the American Federation of Teachers. He likewise traces the debate about metaphysics, democracy, and indoctrination that ensued among the foremost pragmatists of the day. (shrink)
To provide the three-way comparisons needed to test existing theories, we compared (1) most-stressful memories to other memories and (2) involuntary to voluntary memories (3) in 75 community dwelling adults with and 42 without a current diagnosis of posttraumatic stress disorder (PTSD). Each rated their three most-stressful, three most-positive, seven most-important and 15 word-cued autobiographical memories, and completed tests of personality and mood. Involuntary memories were then recorded and rated as they occurred for 2 weeks. Standard mechanisms of cognition and (...) affect applied to extreme events accounted for the properties of stressful memories. Involuntary memories had greater emotional intensity than voluntary memories, but were not more frequently related to traumatic events. The emotional intensity, rehearsal, and centrality to the life story of both voluntary and involuntary memories, rather than incoherence of voluntary traumatic memories and enhanced availability of involuntary traumatic memories, were the properties of autobiographical memories associated with PTSD.

I discuss the early history of holography and explore how perceptions, applications, and forecasts of the subject were shaped by prior experience. I focus on the work of DennisGabor (1900–1979) in England,Yury N. Denisyuk (1927-2005) in the Soviet Union, and Emmett N. Leith (1927–2005) and Juris Upatnieks (b. 1936) in the United States. I show that the evolution of holography was simultaneously promoted and constrained by its identification as an analog of photography, an association that influenced its (...) assessment by successive audiences of practitioners, entrepreneurs, and consumers. One consequence is that holography can be seen as an example of a modern technical subject that has been shaped by cultural influences more powerfully than generally appreciated. Conversely, the understanding of this new science and technology in terms of an older one helps to explain why the cultural effects of holography have been more muted than anticipated by forecasters between the 1960s and 1990s.

The history of holography, the technology of three-dimensional imaging that grew rapidly during the 1960s, has been written primarily by its historical actors and, like many new inventions, its concepts and activities became surrounded by myths and myth-making. The first historical account was disseminated by the central character of this paper, George W. Stroke, while a professor of Electrical Engineering at the University of Michigan. His claims embroiled several workers active in the field of holography and information processing during the (...) 1960s, but transcended personality conflicts: they influenced the early historiography of holography and the awarding of the Nobel Prize for Physics to DennisGabor in 1971. An extended discussion of these episodes, based on archival research, publications analysis and interviews with participants, reveals the importance and extraordinary allure of intellectual priority for practicing scientists, and how its history and explanations are woven from multiple accounts and contemporary interpretations.

Ethnomethodology is in trouble, its conceptual apparatus prone to indifference or misunderstanding both from "conventional" sociologists and from its own practitioners. This article describes some of these loci of confusion and suggests that they have a common root in the relationship between ethnomethodology and conventional sociology. Ethnomethodologists' desire to find a principled theoretical framework for dealing with this relationship is shown to be the common basis for subsequent confusion, and some of the corollaries of their putative solution(s) are elaborated with (...) regard to their philosophical and programmatic implications. Key Words: ethnomethodology social constructionism situated action social structures. (shrink)
Could God have created a better universe? Well, the fundamental scientific laws and parameters of the universe have to be within a certain miniscule range, for a life-sustaining universe to develop: the universe must be ‘Fine Tuned’. Therefore the ‘embryonic universe’ that came into existence with the ‘big bang’ had to be either exactly as it was or within a certain tiny range, for there to develop a life-sustaining universe. If it is better that there exist a life-sustaining universe than (...) not, then it was better that the embryonic universe was one of this small set of very similar embryonic universes than that it was not. Furthermore, there are no firm grounds for claiming that of this small set of very similar embryonic universes, there is one which would have developed into a universe better than ours. Therefore there are no firm grounds for claiming that God could have created a better universe than ours. (shrink)
The focus of this paper is two-fold. First, similarities generated from six semantic models were compared to human ratings of paragraph similarity on two datasets—23 World Entertainment News Network paragraphs and 50 ABC newswire paragraphs. Contrary to findings on smaller textual units such as word associations (Griffiths, Tenenbaum, & Steyvers, 2007), our results suggest that when single paragraphs are compared, simple nonreductive models (word overlap and vector space) can provide better similarity estimates than more complex models (LSA, Topic Model, SpNMF, (...) and CSM). Second, various methods of corpus creation were explored to facilitate the semantic models’ similarity estimates. Removing numeric and single characters, and also truncating document length improved performance. Automated construction of smaller Wikipedia-based corpora proved to be very effective, even improving upon the performance of corpora that had been chosen for the domain. Model performance was further improved by augmenting corpora with dataset paragraphs. (shrink)
This article reports three experiments that investigated the relationship between working memory capacity and syllogistic and five-term series spatial inference. A series of complex and simple verbal and spatial working memory measures were employed. Correlational analyses showed that verbal and spatial working memory span tasks consistently predicted syllogistic and spatial reasoning performance. A confirmatory factor analysis showed that three factors best accounted for the data--a verbal, a spatial, and a general factor. Syllogistic reasoning performance loaded all three factors, whilst spatial (...) reasoning loaded only the general factor. The implications of these findings are discussed in the context of reasoning theories and contemporary accounts of the structure of working memory. (shrink)
The ability to reason independently from one's own goals or beliefs has long been recognised as a key characteristic of the development of formal operational thought. In this article we present the results of a study that examined the correlates of this ability in a group of 10-year-old children ( N = 61). Participants were presented with conditional and relational reasoning items, where the content was manipulated such that the conclusion to the arguments were either congruent, neutral, or incongruent with (...) beliefs, and either logically valid or logically invalid. Participants also received a measure of working memory capacity (the counting span task) and a measure of inhibitory control (the stop signal task). Indices of belief bias and logical reasoning on belief-based problems were predicted independently by both measures. In contrast logical reasoning on belief neutral problems was predicted by working memory alone. The findings suggest that executive functions play a key role in the development of children's ability to decontextualise their thinking. (shrink)
The article reviews recent developments in England in the law of necessity as a defence to crime and calls for its further extension. It argues that the defence of necessity presents the criminal law with difficult questions of competing values and the ordering of harms. English law has taken a nuanced position on the respective roles of the courts and the legislature in the ordering of harms, although the development of the law has been pragmatic rather than coherently theorised. The (...) law has granted necessity some scope as an exculpatory principle in the law of general defences, but it has also respected the primacy of the legislature as the legitimate arbiter of many of the competitions of value that necessity throws up. The recognition of necessity has not been in the form of a single unified defence of that name. Rather it has taken the form of a number of defences, based on a principle of necessity, but with different nomenclature and different rationales. This approach to necessity is defended as right in terms of principle and policy. Any further development of necessity as a general defence should be restricted to two contexts, namely those of emergencies, and of conflicts of duty, where a danger of death or serious injury is present.

This essay describes the Hungarian historical background out of which Michael Polanyi’s lifelong commitment to a liberal, democratic form of government grew. Hungary’s liberal thinkers blossomed in the nineteenth centruy, but their orientation was more political and practical than philosophical. Enlightenment ideas did not penetrate deeply into Hungarian society, which in recent centuries was hampered by its Eastern European and feudal ties. Thus Polanyi felt he had to move to more liberal countries.
We propose a framework for analyzing the development, operation and failure to survive of all things, living, non-living or organized groupings. This framework is a sequence of developments that improve survival capability. Framework processes range from origination of any entity/system, to the development of increased survival capability and development of life-forms and organizations that use intelligence. This work deals with a series of developmental changes that arise from the uncovering of emergent properties. The framework is intended to be general, but (...) we see a potential to apply it to scientific topics such as the exploration of the origin of life or the search for life beyond Earth, and to understand some biological issues in evolution and symbiosis, and also to apply to social systems that do not seem to be operating well, to determine their problems and correct them.

This article combines the disciplines of textual/linguistic analysis, anthropology, and perceptual psychology to examine selected ancient Jewish mystical texts that claim to describe the praxis for ascents into heaven and encounters with angelic spirits in order to reconstruct the psychosocial context of these literary works. Specifically, the article examines Hekhalot or "Divine Palaces" texts that deal with hydromancy, giving attention to their mythic–symbolic assumptions, their described preparatory and triggering rituals, and their accounts of the ASC (altered states of consciousness) visions (...) resulting from these rituals that are experienced by the practitioners. The article suggests that these accounts correlate with ASC practices identified in the literature and additionally suggests that although the mystical texts are written to resemble biblical accounts of revelatory experiences, the texts under consideration are more than works of fabulous imagination; they are literary artifacts of an actual ecstatic ASC praxis among the Jews of Late Antiquity.

Visions of an interconnected future are on the rise that foresee technologies moving toward ubiquitous "everywhere" computing and the rise of the "Internet of Things." This article examines emerging trends in informational connectivity that indicates shifts toward upcoming scenarios of re-imagined geographies and spatial landscapes that are sensored and networked. I examine how the relationships, processes, and flows between people, physical objects, and the environment will make implicit information explicit and engagement between the physical and the digital more commonplace. These (...) are the scenarios presented by emerging applications of location-specific, informationally augmented objects: a real-time sensored future. (shrink)

The primary intent of this project is to encourage increased business ethics research in the area of institutional investing in general and pension fund management in particular. (shrink)
The aim of the present research was to develop a difficulty model for logical reasoning problems involving complex ordered arrays used in the Graduate Record Examination. The approach used involved breaking down the problems into their basic cognitive elements such as the complexity of the rules used, the number of mental models required to represent the problem, and question type. Weightings for these different elements were derived from two experimental studies and from the reasoning literature. Based on these weights, difficulty (...) models were developed which were then tested against new data. The models had excellent predictive validity and showed the relative influence of rule based factors and factors relating to the number of underlying models. Different difficulty models were needed for different question types, suggesting that people used a variety of approaches and, at a wider level, that both mental models and mental rules may be used in reasoning.

Mathematical economic theory is lacking in logical rigour. Even if the mathematics used in constructing formal economic theory is rigorous as pure mathematics, economic theory possesses both mathematical and non-mathematical components. But mathematical reductionism fails to formalize the non-mathematical components of economic theory, and the method of numerics (outlined in this paper) shows how, in simple cases, the two components of economic theory can be formally identified, distinguished, and integrated. However, the real challenge to formalizing economic theory points not to (...) mathematics but to problems of constructing a logic coping with propositional attitudes (belief, preference, intention) that lie at the very heart of economic rationality and can be treated only by means of intensional logic.

Pairing Thus Spoke Zarathustra with On the Genealogy of Morality foregrounds tensions between artistic creation and critical interpretation in Nietzsche's work. From The Birth of Tragedy to his genesis of the concept, Will to Power, Nietzsche describes the real, or ?what is,? in terms of a creative, form-giving force. We might therefore read Zarathustra?a linguistically experimental, richly allegorical, self-reflexive, modernist prose poem?as the pre-eminent, artistic mode of philosophical expression, at least for Nietzsche. But Zarathustra is followed by a sober Abhandlung (...) (treatise), which professes a scientific goal of ?getting to the bottom of things? by uncovering the contingency, origin, and fabricated nature of supposedly eternal, ?given? values. These instantiations of Nietzsche-the-artist and Nietzsche-the-critic suggest art's ?double? or contradictory nature?a nature that accents its kinship with philosophy. Zarathustra and the Genealogy, read together, hint that the destruction of idols?or de-constructive, critical interpretation more generally?is not just supplemental to, but a necessary moment within the aesthetic itself.

For centuries medical schools in Britain and elsewhere had a fairly static curriculum based on what might be called the 'three Rs' of medicine, and consequently had to make room for new subjects as the need arose in a fashion which was sometimes makeshift. However, Southampton University has only had a medical school for six years, and therefore their course on medical ethics and legal medicine was carefully integrated into the curriculum after some preliminary experiments carried out by a subcommittee (...) which is continually reviewing the situation. Medical ethics has now a definite place in the fourth year, preceded by an introduction to ethical problems encountered in medicine in the first year. Not only do members of the medical faculty participate in this teaching but also members of the faculties of law and the arts. (shrink)
Tests of economic theory often focus on choice outcomes and find significant individual differences in these outcomes. This variability may mask universal psychological processes that lead to different choices because of differences across cultures in the information people have available when making decisions. On this view, decision making research within and across cultures must focus on the processes underlying choice.
Different aspects of people's interactions with money are best conceptualized using the drug and tool theories. The key question is when these models of money are most likely to guide behavior. We suggest that the Drug Theory characterizes motivationally active uses of money and that the Tool Theory characterizes behavior in motivationally cool situations. (Published Online April 5 2006).
In the late 16th and early 17th centuries, a number of ‘liberal Jesuit scholastics’ produced the last great synthesis of Aristotelian psychology with Christian theology. In this magnificently sympathetic reconstruction of their systems of the soul, Dennis Des Chene rescues Toletus, Suarez, and the other ‘schoolmen’ from neglect which resulted from scornful dismissals by Descartes and his fellows. Deliberating bypassing the political and medical contexts of their work, and focusing almost exclusively on Jesuit rather than other, ‘dissident’ Renaissance Aristotelianisms, (...) Des Chene focusses intensely on intellectual history, what he calls at one point ‘the flurry of subtleties’ of these astonishing systematic commentaries on Aristotle. (shrink)

Dennis Des Chene's Physiologia: Natural Philosophy in Late Aristotelian and Cartesian Thought reconstructs the discourse of late scholastic natural philosophy, and assesses Descartes' agreements and disagreements. In a critical discussion, I offer a different interpretation of late scholastic theories of final causality and of God's concursus with created efficient causes. Fonseca's and Suárez' conceptions of final causality in nature depend on their claim that a single action can be the action of two agents at once--in particular, of God and (...) of a creature. I discuss both their theory of action and its implications for natural teleology. I then compare Descartes, emphasizing his demolition of the Aristotelian hierarchy of causes, with unmoved movers regulating the action of inferior moved movers. Aristotle argues that unmoved causes are needed to produce a stable world-order; he takes arts as his models of unmoved causes, and uses this model to support natural teleology. Descartes radically simplifies this system by denying all unmoved movers other than God, and denying anything analogous to an art in non-human nature. I explore the implications for Descartes' notion of concursus and his criticism of natural teleology, and discuss his resulting difficulties in explaining natural stability. (shrink)
Hume's essay ‘Of Luxury’ criticizes two extreme and contrasting doctrines: that luxury is always beneficial to society and that it is always baneful. Hume identifies the exponent of the first proposition as Bernard Mandeville in his book The Fable of the Bees, but does not name the second target of his essay. It is most probably John Dennis, one of Mandeville's contemporary critics. The evidence for this is that Hume challenges and contradicts three clearly defined theses advanced in (...) class='Hi'>Dennis's book Vice and Luxury Publick Mischiefs. (shrink)

The problem of foreknowledge and freedom presents a challenge to the defender of traditional Western theism. Nelson Pike has argued that the existence of an essentially omniscient God who possesses foreknowledge is incompatible with human freedom. Pike's opponents in this matter, among whom is Alvin Plantinga, argue that no incompatibility has yet been shown. I shall develop the view that neither Pike nor his opponents have conclusively settled the question whether foreknowledge and freedom are compatible. Furthermore there is a reason (...) why the issue has not been, and may never be, conclusively settled: it is an inherently paradoxical issue. To aid in demonstrating this point I shall discuss a modified version of a paradox that has come to be known as Newcomb's Problem. (shrink)
