    2006-01-01

    In the area of dynamic economics, David Cass's work has spawned a number of important lines of research, including the study of dynamic general equilibrium theory, the concept of sunspot equilibria, and general equilibrium theory when markets are incomplete. Based on these contributions, this volume contains new developments in the field, written by Cass's students and co-authors..

  2. The Ontological Turn Misunderstood: How to Misunderstand David Armstrong’s Theory of Possibility

    OpenAIRE

    Wachter, Daniel von

    2004-01-01

    This article argues that there is a great divide between semantics and metaphysics. Much of what is called metaphysics today is still stuck in the linguistic turn. This is illustrated by showing how Fraser MacBride misunderstands David Armstrong's theory of modality.

    David Adger raises some interesting issues and makes several valuable points in his 'Remarks on Minimalist feature theory and Move' (henceforth MFTM), a response to our review article 'Symptomatic imperfections' (henceforth SI) in this journal (Asudeh and Toivonen 2006), which was in part a review of his Core syntax (Adger 2003). In this response, we address some of the points in MFTM. We would also like to set the record straight about some points in SI which we feel have been misrepresented...

  4. Theory of Money of David Ricardo: Quantity Theory and Theory of Value

    Directory of Open Access Journals (Sweden)

    Susumu Takenaga

    2003-07-01

    Full Text Available What is to be underlined in characterizing the Ricardo’s quantity theory, is that it is a theory of determination of the value of money in a particular situation where money, whatever the form may be, shall be prevented from freely entering or leaving circulation. For Ricardo, the regulation of the value of money by its quantity is a particular case in which the adjustment of the market price to the natural price requires a long period of time. The quantitativist determination is not valid unconditionally, but only when the time of observation is shorter than that of this adjustment. The determination of the value of money is, in any case, barely linked to his theory of the value of commodities. Contrary to the commonly accepted interpretation, Ricardo did not apply to the determination of the value of money any theory of value different from that applied to commodities in general.

  5. Dialectical materialism and the construction of a new quantum theory: David Joseph Bohm, 1917-1992

    Energy Technology Data Exchange (ETDEWEB)

    Forstner, C.

    2005-07-01

    This paper touches on some general questions of theory construction in physics, by presenting a biographical case study of David Bohm through the perspective of Fleckian thought-collectives and their thought-style. In the 1920s a small elite of physicists established the Copenhagen Interpretation of quantum mechanics as a new thought-style in the thought-collective of the physicists. In the following decade the Copenhagen Interpretation was transferred from Europe to the USA, from one thought-collective into another, and was integrated into a specific American thought-style. David Bohm was initiated in this mode of thought during his undergraduate studies at the Pennsylvania State College and his graduate studies at Caltech and the University of California at Berkeley.

  6. The reconstitution of political theory: David Easton, behavioralism, and the long road to system.

    Science.gov (United States)

    Gunnell, John G

    2013-01-01

    During the last half of the twentieth century, the concept of system was arguably the most important concept in the theoretical repertoire of the discipline of American political science. Although systems analysis was broadly employed in the behavioral sciences, David Easton's work was particularly influential in the study of politics. This is in part because he attempted to develop a distinct account of the political system that was not theoretically subservient either to general systems theory or to conceptions of the social system such as that advanced by Talcott Parsons. Although a great deal of attention has been devoted to Easton's theory, the origins and evolution of the system concept in his work have not been carefully reconstructed and analyzed. PMID:23423865

  7. A philosophical analysis of David Orr's theory of ecological literacy: biophilia, ecojustice and moral education in school learning communities

    Science.gov (United States)

    Mitchell, Debra B.; Mueller, Michael P.

    2011-03-01

    In his writings, David Orr claims that the US is in an "ecological crisis" and that this stems from a crisis of education. He outlines a theory of ecological literacy, a mode by which we better learn the ecology of the Earth and live in a sustainable manner. While emphasizing a shock doctrine, the diagnosis of "crisis" may be correct, but it is short-lived for children and adults of the world. In this philosophical analysis of Orr's theory, it is argued that we move beyond the perspective of crisis. By extending Orr's ecological literacy with biophilia and ecojustice and by recognizing the importance of experience-in-learning, science education is envisioned to incorporate values and morals within a longer term ideology of educational reform.

  9. Oral Histories in Meteoritics and Planetary Science—XIX: Klaus Keil

    Science.gov (United States)

    Sears, Derek W. G.

    2012-12-01

    Abstract- Klaus Keil (Fig. 1) grew up in Jena and became interested in meteorites as a student of Fritz Heide. His research for his Dr. rer. nat. became known to Hans Suess who--with some difficulty--arranged for him to move to La Jolla, via Mainz, 6 months before the borders of East Germany were closed. In La Jolla, Klaus became familiar with the electron microprobe, which has remained a central tool in his research and, with Kurt Fredriksson, he confirmed the existence of Urey and Craig's chemical H and L chondrite groups, and added a third group, the LL chondrites. Klaus then moved to NASA Ames where he established a microprobe laboratory, published his definitive paper on enstatite chondrites, and led in the development of the Si(Li) detector and the EDS method of analysis. After 5 years at Ames, Klaus became director of the Institute of Meteoritics at the University of New Mexico where he built up one of the leading meteorite research groups while working on a wide variety of projects, including chondrite groups, chondrules, differentiated meteorites, lunar samples, and Hawai'ian basalts. The basalt studies led to a love of Hawai'i and a move to the University of Hawai'i in 1990, where he has continued a wide variety of meteorite projects, notably the role of volcanism on asteroids. Klaus Keil has received honorary doctorates from Friedrich-Schiller University, Jena, and the University of New Mexico, Albuquerque. He was President of the Meteoritical Society in 1969-1970 and was awarded the Leonard Medal in 1988.1 Klaus Keil at the University of Hawai'i at Manoa, 2007.

  11. Connla's well: An exploration of similar elements of ancient Celtic perspectives and David Bohm's theories in quantum physics from a Jungian perspective

    Science.gov (United States)

    Maciel, Duan

    This dissertation addresses the common elements between ancient Celtic mystical doctrines and philosophy and David Bohm's unique theories in quantum physics through a Jungian lens, using research based in dialogical hermeneutics. The premise of this dissertation is that psi, or the probability wave function of quantum physics, and its world of potentia are the same entities as Jung's objective psyche (or collective unconscious) and its domain, the unus mundus. In addition, the study explores the remarkable similarity between the ancient Celts' Otherworld, quantum physics' world of potentia, and Jung's unus mundus. These similarities argue for an in-depth Jungian analysis of this important but largely neglected mythology. The study explores the supposition, based partially on physicist David Bohm's theories of the implicate and explicate orders, that the above world of potentia intertwines with our three-dimensional world in a reciprocal creativity, designed to enhance both worlds. The study further advocates a greater emphasis on the creative arts therapies in the therapeutic situation, based on the above reciprocity. It is argued that this emphasis on creativity in the temenos may activate a profound "quantum leap" of insight in the analysand, most likely due to the reciprocity in which the objective psyche responds uniquely to the particular and individual creativity offered in order to heal the personal psyche. As we creatively access the objective psyche, that entity responds in kind, giving us new understanding and allowing us to change our attitudes and to further individuation, which in turn enhances the objective psyche. In addition, a psyche of reality is postulated in which Jung's concept of the objective psyche is expanded from the collective unconscious of humankind to a collective unconscious of All That Is, reflecting the findings in quantum physics that our universe is self-aware, organic, and holistic rather than mechanical and fragmented.

  16. Extending David Horrobin's membrane phospholipid theory of schizophrenia: overactivity of cytosolic phospholipase A(2) in the brain is caused by overdrive of coupled serotonergic 5HT(2A/2C) receptors in response to stress.

    Science.gov (United States)

    Eggers, Arnold E

    2012-12-01

    David Horrobin's membrane phospholipid theory of schizophrenia has held up well over time because his therapeutic prediction that dietary supplementation with eicosapentaenoic acid (EPA) would have a therapeutic effect has been partially verified and undergoes continued testing. In the final version of his theory, he hypothesized that there was hyperactivity of phosphoslipase A(2) (PLA(2)) or a related enzyme but did not explain how the hyperactivity came about. It is known that serotonergic 5HT(2A/2C) receptors are coupled to PLA(2), which hydrolyzes both arachidonic acid (AA) and EPA from diacylglycerides at the sn-2 position. In this paper, Horrobin's theory is combined with a previously published theory of chronic stress in which it was hypothesized that a disinhibited dorsal raphe nucleus, the principal nucleus of the serotonergic system, can organize the neuropathology of diseases such as migraine, hypertension, and the metabolic syndrome. The new or combined theory is that schizophrenia is a disease of chronic stress in which a disinhibited DRN causes widespread serotonergic overdrive in the cerebral cortex. This in turn causes overdrive of cPLA(2) and both central and peripheral depletion of AA and EPA. Because EPA is present in smaller amounts, it falls below threshold for maintaining an intracellular balance between AA-derived and EPA-derived second messenger cascades, which leads to abnormal patterns of neuronal firing. There are two causes of neuronal dysfunction: the disinhibited DRN and EPA depletion. Schizophrenia is statistically associated with metabolic syndrome, hypertension, and migraine because they form a cluster of diseases with similar pathophysiology. The theory provides an explanation for both the central and peripheral phospholipid abnormalities in schizophrenia. It also explains the role of stress in schizophrenia, elevated serum PLA(2) activity in schizophrenia, the relationship between untreated schizophrenia and metabolic syndrome, and the therapeutic rationale for EPA.

  17. Memories of David Kirzhnits

    2013-06-01

    In the mid-1950s, a new staff member appeared at the Theory Division of the Physical Institute of the Academy of Sciences (FIAN): David Abramovich Kirzhnits. A Moscow State University alumnus, after graduation he had been assigned to a large defense plant in the city of Gorky, where he had worked for several years as an engineer. He was "liberated" from there by Igor Evgenyevich Tamm, our department head, who managed to transfer him to FIAN. Igor Evgenyevich knew D. A. Kirzhnits - they had met in Moscow before Kirzhnits finished university. At that time Kirzhnits was performing thesis work with professor A. S. Kompaneyets as academic adviser. At his adviser's suggestion, D. Kirzhnits consulted with I. E. Tamm on questions pertaining to the thesis topic. I. E. Tamm took a great liking for the diploma student, and he even wanted to recruit D. A. Kirzhnits for the Theory Division immediately after graduation. But at that time (1949) this proved impossible for several reasons. First, D. Kirzhnits was, as they say, an "invalid of the fifth group" - a Jew - which during those years of violent struggle against cosmopolitanismb often proved an obstacle in looking for work. Second, during the years of mass repressions D. Kirzhnits' father had been arrested on treason charges (according to the charges, he had wanted to sell the Far East to Japan). After intensive investigation his father was released, but he lived only a little longer. Reports of this also could have impeded his acceptance. Third, Igor Evgenyevich didn't have enough weight in officials' eyes at that time and so was unable to overcome "first" and "second."...

    It is with great sadness that we learned that our friend and former colleague, David Warner, passed away on Christmas Eve. The funeral was held the following Monday. David was a "linac man". His career centred around linacs, but with a multitude of different subjects. He began at CERN by building the 3 MeV linac in the extension of the South Hall. He did pioneering work on this machine, which paved the way towards the design of the Alvarez cavities for the CERN Linac 2, for which he was responsible. After this challenge was successfully finished, David was the first member of the small but growing team, that was in charge of building the LEP Injector Linacs (LIL). After having been recognised as a proton linac expert, he quickly converted to electron linacs where he soon became the respected key expert for the design, parameters and ultimate performance of LIL. His predilection for precise and detailed documentation, and his vision that the know-how acquired with LIL should be preserved a...

The inner sleeve booklet is titled The Diary of Nathan Adler, or the Ritual Art-Murder of Baby Grace Blue: A non-linear Gothic Drama Hyper-Cycle. Behind this long-winded title, is the story of a murder, narrated by several characters through both text, music and images. Bowie, however, is the narrator of all these different voices, using technology to distort his voice into these different characters as separate entities. His voice and presence haunts the entire album in uncanny forms, just as all images in the booklet are distorted images of Bowie himself, made into uncanny doubles. The story begins with the murder of Baby Grace Blue, who is enacted by Bowie himself. Symbolically, Bowie is murdered by himself, while Baby Grace haunts the entire album's Gothic and labyrinthine structure. My paper will focus on the mediated double of David Bowie, his ventriloquist voice and simulacral presence as character, creator and ghost. I will problematize the notion of an outside to the album, focussing on what can be termed the album's hauntological status.

  13. Paranoid, moi? : Erasing David

    DEFF Research Database (Denmark)

    Pedersen, Peter Ole; LØhmann Stephensen, Jan

    2010-01-01

    The article discusses the relationship between the subject of surveillance and documentary film. As its main example, it uses David Bonds Erasing David from 2009. The genre-specific and film historic aspects of this documentary is analysed and in a further perspective it serves as the point of departure for a more general theoretical discussion of surveillance. Through the treatment of its content and the conceptual framework, Bonds film place itself within what could appropriately be termed the “popular cultural documentary”. What characterises this part of the genre is a critical approach bordering on activism. This is sought combined with the ability to entertain the audience through elements of fiction and comic relief while attempting an analysis of a current and often controversial subject. Michael Moore’s productions are the most successful examples of this filmmaking strategy and two film analytical approaches based on Moore’s 1989 debut Roger & Me is used evaluate the aesthetic and conceptual coherence in Bonds work.     Following this, a three-part taxonomy for the analytical and normative understand of the surveillance phenomenon and its socio-cultural and political implications is established. These are termed: The critical-subversive, the Para cultural and the affirmative mode of understanding. The critical-subversive mode is comparable to the expository documentary form. A strategy, that whether academic or aesthetic, aims at the disclosure of hidden societal mechanisms by way of facts. In a theoretical perspective, this is discussed with Foucault’s idea of the panopticon and more recently Bruno Latour’s corrective counter-concept oligopticon. The Para cultural intervention is explained with Michel de Certeau’s understanding of ‘tactical re-appropriation’. This strategy, like the previous one, is sceptical of a surveillance society and its implications, though it establishes a different, temporary form of critical stanza. The last mode of portrayal is the affirmative. This is directly connectedto the popular cultural representation of surveillance technologies. According to the German art historian O. K. Werkmeister, these are ascribed an almost omnipresent potential. This creates an internalisation of the surveillance culture, one which is paradoxically endorsed by both its supporters and critics.                       Both the theoretical perspective and the film analytical approach to Bonds film determine problematic weaknesses in his project. Bond tends to invest more in cracking the ‘formula’ for a successful presentation of his material, than discovering new formalistic or analytical territory in the filmic exposure of current surveillance culture.

    Science.gov (United States)

    Leigh, David A.; Pritchard, Robin G.; Stephens, Alexander J.

    2014-11-01

    We describe the synthesis of a [2]catenane that consists of two triply entwined 114-membered rings, a molecular link. The woven scaffold is a hexameric circular helicate generated by the assembly of six tris(bipyridine) ligands with six iron(II) cations, with the size of the helicate promoted by the use of sulfate counterions. The structure of the ligand extension directs subsequent covalent capture of the catenane by ring-closing olefin metathesis. Confirmation of the Star of David topology (two rings, six crossings) is provided by NMR spectroscopy, mass spectrometry and X-ray crystallography. Extraction of the iron(II) ions with tetrasodium ethylenediaminetetraacetate affords the wholly organic molecular link. The self-assembly of interwoven circular frameworks of controlled size, and their subsequent closure by multiple directed covalent bond-forming reactions, provides a powerful strategy for the synthesis of molecular topologies of ever-increasing complexity.

  10. Do Surrealismo em David Lynch

    Directory of Open Access Journals (Sweden)

    Mirian Tavares

    2009-01-01

    Full Text Available O surrealismo, como a arte do seu tempo, propõe uma nova estética, capaz de extrair o belo do absurdo e de instaurar o desvio para que daí surja, de fato, o real. Através da análise de algumas obras de David Lynch e dos livros Les champs magnétiques de Breton e Philippe Soupault e Poisson soluble, de Breton, irei mostrar a pertinência da designação surrealista para a obra do cineasta norte-americano. Lynch, como os surrealistas, constrói uma operação dialética entre o racional/irracional. Ao mesmo tempo em que opera no campo artístico em direção à irracionalidade absoluta, Lynch não nega a sua inserção na sociedade. Acredito que o realizador, como os surrealistas, tenha conseguido encontrar um equilíbrio entre as duas formas de se estar no mundo, racional/irracional, jogando com suas antíteses. O prazer do jogo surrealista consiste em ir até as profundezas do inconsciente e retornar com matéria suficiente para fazer uma obra de arte.Surrealism, as the art of its time, proposes a new aesthetics, one that is able to extract the beautiful from the absurd and to establish the swerve from the standard, from which, in fact, the real comes through. Through the analysis of some works by David Lynch, of Breton and Soupault's Les champs magnétiques, and of Breton's Poisson soluble, I will attempt to show the relevance of the surrealist designation for the work of the American filmmaker. Lynch, like the surrealists, builds a dialectic operation between the rational and the irrational. While operating in the artistic field towards absolute irrationality, Lynch does not deny its role in society. It is my belief that the director, as the surrealists, has managed to find a balance between the two ways of being in the world: rational and irrational; by playing with their antitheses. The pleasure of the surrealist game is to go to the depths of the unconscious and return with sufficient material to make a work of art out of it.

  11. The Evolving Dynamics of Organizational Capabilities : An Interview with David J. Teece

    DEFF Research Database (Denmark)

    Augier, Mie-Sophia

    2004-01-01

    In this paper, Mie Augier provides a rich description of the intellectual traditions, the signifi-cant people and academic institutions that in some way or another made a difference to Davis Teece's own intellectual development. In this sense, it is a dynamic account of the emerging career of a distinguished scholar - but not only that. It is also a description of the co-development of three major disciplinary fields; organization theory, economics and strategic management during three decades or so. David Teece has made several important contribu-tions, perhaps most notably to economics (on the theory of the firm and transaction cost eco-nomics) and strategic management (on dynamic capabilities) while drawing upon organization theory and notions such as organizational routines and bounded rationality. In addition, Augier also provides an interview with David Teece, a true scholar still unsettled with what has been achieved so far - in all three fields: `Maybe I'm wrong; and maybe technology is a special caseand maybe technology and organization do not belong at the core of the theory of the firm. My intuition tells me otherwise.' (David Teece, quoted in this issue).

  15. David Harvey’s contribution to urban sociology

    Directory of Open Access Journals (Sweden)

    Cvjetkovi? Marija

    2015-01-01

    Full Text Available David Harvey is a neo-Marxist theorist influential in many disciplines. This paper analyses his specific use of Marx’s theory as a contribution to urban sociology. Observing cities in the context of a constant need of capitalism to overcome the problem of over-accumulation of capital, urbanization is seen as an important factor of capitalist development. Methods of temporary relocation and resolutions of capitalist contradictions, with the help of so-called accumulation by dispossession, are intensified in neo-liberalism, which is seen as a project for the restoration of class power. Therefore, Harvey demands more equitable cities in which the interest of private capital will not be the main factor of their shaping. Harvey’s Marxism is alluring, but it is also the subject of numerous criticisms.

    From left to right: David Politzer, David Gross and Frank Wilczek. For their understanding of counter-intuitive aspects of the strong force, which governs quarks inside protons and neutrons, on 5 October three American physicists were awarded the 2004 Nobel Prize in Physics. David J. Gross (Kavli Institute of Theoretical Physics, University of California, Santa Barbara), H. David Politzer (California Institute of Technology), and Frank Wilczek (Massachusetts Institute of Technology) made a key theoretical discovery with a surprising result: the closer quarks are together, the weaker the force - opposite to what is seen with electromagnetism and gravity. Rather, the strong force is analogous to a rubber band stretching, where the force increases as the quarks get farther apart. These physicists discovered this property of quarks, known as asymptotic freedom, in 1976. It later became a key part of the theory of quantum chromodynamics (QCD) and the Standard Model, the current best theory to describe the interac...

  1. Obituary: David Stanley Evans, 1916-2004

    Science.gov (United States)

    Bash, Frank N.

    2005-12-01

    David Stanley Evans died on 14 November 2004 in Austin, Texas. He was a noted observational astronomer whose career was divided between South Africa and Texas. He also used the extensive historical collections at the University of Texas to write several books on the history of astronomy. He was born in Cardiff, Wales on 28 January 1916. David received his BA degree in mathematics in 1937 from Kings College, Cambridge. He became a PhD student at Cambridge Observatory in 1937, and was one of Sir Arthur Eddington's last surviving students. He received his PhD degree in 1941 with a dissertation entitled, "The Formation of the Balmer Series of Hydrogen in Stellar Atmospheres." He was a conscientious objector to war and, thus, spent the war years at Oxford working with physicist Kurt Mendelssohn on medical problems, involving cadavers, relating to the war. During these years, David was scientific editor of "Discovery", and he was editor of "The Observatory". David left England in 1946 in order to take up the position of Second Assistant at the Radcliffe Observatory, Pretoria, South Africa. He and H. Knox Shaw were the entire staff after R. O. Redman left, and they aluminized and installed the mirrors in the 74-inch telescope. His notable scientific contribution was to use lunar occultations to measure stellar angular diameters during the 1950s. He succeeded in determining the angular diameter of Antares and determined that Arcturus was not circular but had an elliptical shape. The elliptical shape was later shown to be an instrumental artifact, but the utility of using lunar occultations to measure stellar diameters and stellar multiplicity was conclusively demonstrated. T. Gold presented David's paper on lunar occultation angular diameters at the January 1953 meeting of the Royal Astronomical Society. For the rest of his life, David resented Gold's remarks, because he felt that he had been ridiculed. By 1953, David Evans was Chief Assistant at the Royal Observatory headquartered in Cape Town, South Africa. David had designed and built a Newtonian spectrograph for the 74-inch Radcliffe Telescope with which he measured the first southern galaxy redshifts. David and his family spent 1965-66 in Austin, Texas, where he was a National Science Foundation Senior Visiting Scientist at the University of Texas and McDonald Observatory. They moved permanently to Austin in 1968 and David became a Professor of Astronomy and Associate Director of McDonald Observatory at the University of Texas at Austin. At McDonald Observatory, R. E. Nather had devised a high-speed photometer capable of measuring millisecond time-scale changes in brightness and with Brian Warner, he invented "high-speed astronomy". This instrument caused Evans to revive his occultation program and, over the next twenty years, he produced the major part of the angular diameters of late-type stars with his students and collaborators. In addition, David and collaborators used the extensive collections of the University of Texas to write "Herschel at the Cape". David was also involved in observing the occultation of ? Sco by Jupiter in 1972 and in observing, during a solar eclipse in 1973, the gravitational deflections in the positions of stars whose light passes near to the Sun. The eclipse was observed from Mauritania, and the observations confirmed Einstein's prediction again. David Evans and his students studied late-type stars that have large star-spots and others that flare. In addition, they studied stars whose lunar occultation observations had revealed them to be double or even more than two stars. David Evans's major scientific contribution was an application of his stellar angular diameters to deduce the surface brightness of stars with the result that with suitable color indices one could use photometry to deduce the angular diameter of stars. This is applicable to stars which can never be occulted by the Moon, and its application to Cepheid variable stars has yielded their distances. This relation between angular d

    Full Text Available While historical materialism and evolutionism provide similar explanations and ideas regarding the cause of long-term social change, the two theories are rarely used in conjunction with one another. In Deep History,the author David Laibman addresses some of the standard questions of evolutionary social theory and attempts to bridge the two concepts, by showing that historical and materialist explanations are present in both Marxian and evolutionary interpretations of history. His goal: develop a Marxist theory of history from an evolutionist perspective, and surmount the traditional confines of historical materialism, so as to embrace evolutionary conceptions in explaining social change. However, the unbalanced research methodology limits the reach and depth of Laibman’s contribution. The two main shortcomings of his work are discussed in the following sections: The Audience Problem and The Evolutionary Problem.

  9. Aritmetizando la geometría desde dentro: el cálculo de segmentos de David Hilbert / Arithmetizing the geometry from inside: David Hilbert's segment calculus

    2015-03-01

    Full Text Available Sobre la base que aportan las notas manuscritas de David Hilbert para cursos sobre geometría, el artículo procura contextualizar y analizar una de las contribuciones más importantes y novedosas de su célebre monografía Fundamentos de la geometría (1899), a saber: el cálculo de segmentos lineales (St [...] reckenrechnungen). Se argumenta que, además de ser un resultado matemático importante, Hilbert depositó en su aritmética de segmentos un destacado significado epistemológico y metodológico. En particular, se afirma que para Hilbert este resultado representaba un claro ejemplo de uno de los rasgos más fructíferos y atractivos de su nuevo método axiomático formal, o sea, la capacidad de descubrir y exhibir conexiones estructurales o internas entre diferentes teorías matemáticas. Abstract in english On the basis of a set of unpublished notes for lecture courses on geometry, the paper seeks to contextualize and analyze one of the most important and original contributions of David Hilbert's celebrated monograph Foundations of Geometry (1899), namely its arithmetic of line segments (Streckenrechnu [...] ngen). It is argued that Hilbert attributed to his arithmetic of segments an important epistemological and methodological meaning, in addition to its relevance as an original mathematical result. In particular, it is claimed that for Hilbert his arithmetic of segments represented a clear example of one of the most fruitful and attractive traits of his new formal axiomatic method, i.e., the power to discover and exhibit inner or structural connections among different mathematical theories.

  10. Boundaries and interfaces in materials: The David A. Smith symposium

    International Nuclear Information System (INIS)

    Just over a year ago David Smith died. Then the loss of a distinguished scientist and dedicated teacher was mourned. Now it is time to celebrate his accomplishments both as a scientist and teacher and this book serves as a reminder of his many contributions to the field of boundaries and interfaces. Researchers from ten countries contributed their work to the symposium, many of whom were former students of David from his years in Oxford. This emphasizes David's tremendous effect on the career of many established scientists through his role as both a teacher and an advisor. Separate abstracts were prepared for 38 papers in this book

  7. Las biografías criminales de David Viñas

    Directory of Open Access Journals (Sweden)

    Román Setton

    2014-06-01

    Full Text Available Con el seudónimo de Pedro Pago, David Viñas escribió al comienzo de su carrera como narrador tres novelas sobre bandidos célebres argentinos: Chicho Grande, Chicho Chico y Mate Cocido. Publicadas en 1953 en la colección Crimen, estas novelas casi no han recibido atención. Este trabajo se propone mostrar que estos textos adelantan aspectos fundamentales de la narrativa de Viñas, así como de sus guiones para el cine. Asimismo, estos relatos son significativos desde la perspectiva de la historia del policial argentino. En contraste con la historización llevada a cabo por Walsh ese año (1953, que pone en el centro el relato de enigma, las novelas de la colección Crimen proponen una tradición diferente, que atiende menos al misterio y la solución deductiva que a la biografía criminal y sus determinaciones sociales.

  8. David and Shimei: Innocent victim and perpetrator?

    Full Text Available Feeding on the current social anxiety in the country that is defined by racial lines, the paper suggests the possibility of a theology for the 'retributed', i.e. those who undergo justice in terms of affirmative action or land repossession. Employing Ndebele's thoughts on the folktale The lion and t [...] he rabbit and the issue of justice in Lars von Trier's Dogville as its matrices, the paper enquires into the roles of perpetrator or victim Shimei and David play to each other in Samuel-Kings in order to see whether Shimei's death constitutes retributive justice or whether there is some social benefit in turning him into a purificatory sacrifice in a Girardian sense.

    David Lasser was one of the founders of the American Interplanetary Society (later known as the American Rocket Society) and author of the first English-language book (in 1931) on the use of rockets for human spaceflight. His involvement in the fledgling spaceflight movement was short-lived as he moved on to pursue a distinguished, if turbulent, career in the labor movement. In lieu of an oral history, Mr. Lasser provided his recollections on the pioneering days of rocketry and his thoughts on mankind's destiny in space. This paper provides an overview of Mr. Lasser's life and accomplishments as an American spaceflight visionary, along with a compilation of the information that he graciously provided.

    Thirty years ago, technology companies began nestling their facilities close to academia, and the idea of the university research park was born. Soon after, the concept took off in the field of medicine, and today it's not hard to find such innovation hubs that house biomedical startups drawing on the brainpower of professors and students alike. In late September, the Tucson, Arizona-based Association of University Research Parks--which includes about 170 research parks--announced that David Baker would serve as president of the organization's board of directors for the next year and help guide its strategic goals for the next five years. Baker, who is also the executive director of the University Technology Park at the Illinois Institute of Technology in Chicago, spoke with Roxanne Khamsi about how the organization hopes to branch out and transform these workplaces.

    Ross, Lee; Kavanagh, David

    2013-09-01

    Presents an obituary for David L. Rosenhan (1929-2012). A distinguished psychologist and professor emeritus at Stanford University, Rosenhan died February 6, 2012, at the age of 82, after a long illness. Born in Jersey City, New Jersey, on November 22, 1929, he received a bachelor's degree in mathematics (1951) from Yeshiva College and a master's degree in economics (1953) and a doctorate in psychology (1958) from Columbia University. A professor of law and of psychology at Stanford University from 1971 until his retirement in 1998, Rosenhan was a pioneer in applying psychological methods to the practice of law, including the examination of expert witnesses, jury selection, and jury deliberation. A former president of the American Psychology-Law Society and of the American Board of Forensic Psychology, Rosenhan was a fellow of the American Association for the Advancement of Science, of the American Psychological Association, and of the American Psychological Society. Before joining the Stanford Law School faculty, he was a member of the faculties of Swarthmore College, Princeton University, Haverford College, and the University of Pennsylvania. He also served as a research psychologist at the Educational Testing Service. As generations of Stanford students can attest, David Rosenhan was a spellbinding lecturer who managed to convey the sense that he was speaking to each individual, no matter how large the group. To his graduate students, he was consistently encouraging and optimistic, always ready to share a joke or story, and gently encouraging of their creativity and progressive independence as researchers. The lessons he cared most about offering, in the classroom as in his research, were about human dignity and the need to confront abuse of power and human frailties. PMID:24016118

Mais precisamente, o texto destaca a estratégia de formalização adotada por Davi [...] d G. Champernowne em seu artigo intitulado "Unemployment, Basic and Monetary: the classical analysis and the keynesian", publicado em 1935-36 na Review of Economic Studies. Chamamos a atenção para o fato dele distinguir a teoria clássica da teoria de Keynes não apenas pelos pressupostos adotados por cada teoria, mas principalmente pela construção de subsistemas a partir de um sistema geral, com características recursivas (relações de causalidade) distintas. As explicações "em prosa", a descrição algébrica das funções comportamentais e condições de equilíbrio e a ilustração por meio de diagramas, além da escolha de conjuntos específicos de variáveis para representar cada uma das teorias e suas diferentes versões são aspectos deste artigo de Champernowne que merecem uma análise mais minuciosa. Abstract in english This paper aims at emphasizing a feature that has been somewhat neglected by studies dealing with the formalization of John Maynard Keynes's General Theory of Employment, Interest and Money (1936). Specifically, this paper stresses the formalization strategy David G. Champernowne applied in his essa [...] y "Unemployment, Basic and Monetary: the classical analysis and the Keynesian", published in 1935-36 in the Review of Economic Studies. We underline the fact that he distinguishes the Classical Analysis from the Keynesian not only by means of the different assumptions underlying each theory but mainly through the construction of sub-systems based on a general system, with distinctive recursive features (causal relations). His literary explanations, the algebraic descriptions of the behavioral functions and of the equilibrium conditions and his diagrammatical illustrations as well as the choice of specific groups of variables to stand for each of these theories (and variants) are features of this Champernowne's essay that deserve a more attentive assessment.

Una interpretación naturalista pretende, entre tanto, atribuir nuevos sentidos al aspecto afirmativo de su filosofía, mostrando que Hume estaba interesado en aplicar el método experimental al estudio de la natura [...] leza humana. Su filosofía sería vista como una construcción sobre bases naturalísticas de una teoría del conocimiento y de la naturaleza humana. Eruditos como Kevin Meeker pretenden afirmar que las conclusiones escépticas presentes en la obra de Hume imposibilitan una interpretación naturalista, prevaleciendo, así, una conclusión escéptica radical, de que el conocimiento no es posible. Se pretende mostrar, por medio de un examen de los textos de Hume, que el concepto de conocimiento del que parte Meeker, su concepción de naturalismo e incluso su concepción del papel del escepticismo en la filosofía de Hume están equivocados y que la opción naturalista es lo que da más sentido entre las interpretaciones posibles de su filosofía.

The naturalistic approach aims, about this point, provides new meanings to the affirmative aspect of his philosophy, by showing that Hume was interested in apply the experimental method in the study of human nature [...] . Then, his philosophy could be seen as a construction - over naturalistic basis - of a theory of knowledge and human nature. Some critics like Kevin Meeker intent to claim that the skeptic conclusions, present in Hume’s works makes impossible such a naturalistic view, prevailing after all the skeptical conclusion of the impossibility of knowledge. This enquiry wants to show, by an analysis of Hume’s texts, that the conceptions of knowledge, naturalism and even this conception of skepticism, applied to Hume’s philosophy is mistaken, and that the naturalistic outcome makes more sense, among the possible interpretations of Hume’s philosophy.

  15. Waltz's Theory of Theory

    DEFF Research Database (Denmark)

    Wæver, Ole

    2009-01-01

    Kenneth N. Waltz's 1979 book, Theory of International Politics, is the most influential in the history of the discipline. It worked its effects to a large extent through raising the bar for what counted as theoretical work, in effect reshaping not only realism but rivals like liberalism and reflectivism. Yet, ironically, there has been little attention to Waltz's very explicit and original arguments about the nature of theory. This article explores and explicates Waltz's theory of theory. Central attention is paid to his definition of theory as ‘a picture, mentally formed' and to the radical anti-empiricism and anti-positivism of his position. Followers and critics alike have treated Waltzian neorealism as if it was at bottom a formal proposition about cause-effect relations. The extreme case of Waltz being so victorious in the discipline, and yet being consistently mis-interpreted on the question of theory, shows the power of a dominant philosophy of science in US IR, and thus the challenge facing any ambitious theorising. The article suggests a possible movement of fronts away from the ‘fourth debate' between rationalism and reflectivism towards one of theory against empiricism. To help this new agenda, the article introduces a key literature from philosophy of science about the structure of theory, and particularly about the way even natural science uses theory very differently from what IRs mainstream thinks - and much more like the way Waltz wants his theory used.

  17. David and Uriah (with an occasional appearance by Uriah's wife) - Reading and re-reading 2 Samuel 11

    Scientific Electronic Library Online (English)

    David G., Firth.

    Full Text Available The interpretation of 2 Samuel 11 has been built around three points: 1. The primacy of the relationship between David and Bathsheba; 2. Uriah dies in a cover-up; 3. The narrative is full of ambiguity. This paper explores the narrative from the perspective of the ambiguities employed, showing that t [...] he third point undermines the frst two. This is achieved by drawing on Genette's theory of anachrony which emerges as an important historiographical feature in Samuel. The text is meant to be read and then re-read as each anachrony is encountered, thus coming to a clearer understanding of what is meant by the narrator's closing comment.

    Full Text Available The following paper will offer an interpretation of David Lynch's film The Elephant Man, and its representations of late-Victorian London as a monstrous and deformed body. Besides tracing these themes in a discussion of exemplary scenes of the film, I wish to illuminate how underlying notions of monstrosity in the writings of Victorian urban explorers and reformers contributed to ideas and anxieties about the body and domesticity, and helped to promote the image of a clean, sanitized and civilized city. I will make use of a range of theoretical and historical approaches developed within and inbetween a variety of disciplines such as anthropology, geography and architectural history, as well as literary studies, film theory and psychoanalysis, and, in so doing, aim to complicate the image of the monstrous metropolis.

    2008-11-01

    Full Text Available

    Today David Mitrany is best known for his work on international functionalism, which influenced the development of European integration and the organisation of United Nations specialised agencies. What is often ignored in the West is his work on South-East Europe. During the inter-war period Mitrany studied both the operation of war government and the subsequent peasant revolution in the Balkans. War government demonstrated that political organisation could bridge the gap between social action and private property, while the peasant social revolution showed that the abstract economics associated with both capitalist and Marxist economics was not applicable outside of urban industrial production. It was through his studies of South-East Europe that Mitrany drew many of the lessons and concepts that were to form the foundations of his international theory.

  1. Hacking the aesthetic: David Haines and Joyce Hinterding's new ecologies of signal

    Directory of Open Access Journals (Sweden)

    Andrew Murphie

    2012-06-01

    Full Text Available Award winning Australian electronic artists David Haines and Joyce Hinterding's installation work is discussed as “signal-work.” Their work reconfigures signal within original assemblages involving subtle audio, high resolution video (both recorded and animated, kilometers of coiled copper wire, antennae or home-built electronics, electrostatic disturbances, the like of very low frequency radiation from the Milky Way, and cross-signal processing. The article develops a context for thinking about the work in terms of Whitehead's process philosophy, as this is relevant to media theory, as well as concepts of plural ecology and ongoing differentiation drawn from Bateson and Guattari. Signal processing is seen as key to all this. The article argues that in Hinterding and Haines’ signal-work new sensations are produced, outside of the normal “syntax” of some models of aesthetic experience. This challenges some aspects of thinking about both aesthetics and political ecology.

    2008-08-01

    How deeply honoured I am to have the opportunity to express my thoughts at this delightful celebration of David's achievements, so far, in his remarkable career. I have been asked to center my remarks on David's contributions to the mentoring and professional development of scientists early in their careers. This is a topic that I am more than happy to reflect on, because it gives me the opportunity to recall the exciting period I spent as one of David's postgraduate students at Imperial College in the early 1980s. It also gives me the chance to publicly express my gratitude to David for the opportunities he created for me at that time, as well as for the interest and care he has shown in my career and well-being ever since, as we have met up and exchanged news and ideas around the world: in New Mexico and Colorado, in Cancun, Paris and Trieste, at numerous March Meetings of the American Physical Society and, of course in London, Oxford, and my home town, Champaign-Urbana, location of the University of Illinois. I have been a member of David's circle for 25 years now, and I would like to tell you a little about how this came to be. Not because of what this says about me, but, rather, because of what it tells you about David and the rich generosity of his spirit and effort when it comes to supporting the underdog. I was indeed one such underdog—and that's putting it charitably—when I first met David in September of 1982, not long before the academic year was to begin. I had heard about the exciting circle of physical and mathematical ideas swirling around the spin glass question during the previous year, which I had spent at the University of California's Los Angeles campus, through an opportunity kindly arranged, as it happens, by Sam Edwards. But I was eager to return to the UK for postgraduate studies and to work on spin glasses, so I simply showed up at David's Imperial College office, unannounced (if I remember correctly). And with his characteristic courtesy David kindly invited me in and we chatted about physics. After a while, I summoned up the courage to ask if I could do postgraduate research. At Imperial College. Under David's supervision. That term! And, to my eternal delight, he agreed. And even more than that, shortly thereafter he set about the task of finding a studentship to support me. This generosity of spirit towards people at early stages in their careers is by no means confined to members of David's own research group. One of David's most remarkable and impressive qualities is his ability to recognise and be an early proponent of exciting work being done by young and not yet widely known researchers, and to enthusiastically foster the dissemination of this work. Jorge Kurchan has told me how David was one of the very first established scientists to take a close interest in Jorge's now-famous work, done jointly with Leticia Cugliandolo, on the dynamics of spin glasses, and that this interest and the invitations, discussions and talks that followed from it, were a tremendous source of inspiration and encouragement to Jorge and Leticia. Jorge is but one of several people who have told me how grateful and impressed they have been by David's similar treatment of them, and for his invitations to visit Oxford and benefit from interacting with and being stimulated by the theoretical physics group there. But David's dedication to others is by no means restricted to his juniors. All of us who have got to know David are deeply aware of the devotion he has to his scientific mentors, Sam Edwards and Walter Kohn, and the rightful pride he takes in being a member of their scientific families. With postgraduate and postdoctoral advisors in Sam Edwards and Walter Kohn, with professorships at Imperial College and then Oxford University, with election to Fellowship at the Royal Society and an invitation to deliver its Bakerian Lecture, and with the Dirac Medal from the Institute of Physics, David more or less defines 'the scientific establishment'. But I don't think he sees himself quite in this vein, and this is b

    Why do we need a formalization of the notion of algorithm or effective computation? In order to show that a specific problem is algorithmically solvable, it is sufficient to provide an algorithm that solves it in a sufficiently precise manner. However, in order to prove that a problem is in principle not solvable by an algorithm, a rigorous formalism is necessary that allows mathematical proofs. The need for such a formalism became apparent in the studies of David Hilbert (1900) on the founda...

  18. Obituary: David Q. Wark, 1918-2002

    Science.gov (United States)

    McMillin, Larry Max

    2003-12-01

    David Q. Wark, a research meteorologist at the National Environmental Satellite, Data, and Information Service of the National Oceanic and Atmospheric Administration (NOAA/NESDIS) and its predecessor organizations for 55 years, died of cancer 30 July 2002. He will be long remembered for his seminal contributions to the weather satellite program. A pioneer in the use of satellite sensors to provide observations of the Earth's environment for application to weather forecasting and atmospheric science, Dr. Wark was noted for his brilliant insights, dedication, and exceptional scientific achievements. He developed many of the theoretical and experimental techniques on which NOAA's current multi- billion-dollar meteorological satellite program is based. In the 1960's and early 1970's, he and his NOAA colleague Donald Hilleary were the motivating force and principal investigators for the first satellite instruments dedicated to sounding the atmosphere for temperature and water-vapor. These instruments included the Satellite Infra-Red Spectrometer (SIRS)-A and -B and the Vertical Temperature Profile Radiometer (VTPR), which were flown on NASA's Nimbus satellites and NOAA's ITOS-D satellites, respectively. With colleague Henry Fleming, he formulated the radiative transfer equation that quantifies the spectral radiances of the Earth and its atmosphere (measured at satellite altitude) and inverted that equation mathematically to infer the atmospheric temperature profile from satellite-based measurements of those radiances. A difficulty they had to overcome was that the mathematical problem is ill-posed, i.e., it admits of an infinite number of solutions. They arrived at a unique solution via an innovative application of a-priori information on the atmospheric state. This work was described in the landmark 1965 Wark and Fleming paper in the American Meteorological Society's Monthly Weather Review. From that early period until just weeks before his death, Dr. Wark continued his work at the Office of Research and Applications in NOAA/NESDIS on developing advanced techniques for sounding the atmosphere from satellites. Dr. Wark's work in remote sensing of the Earth's atmosphere and surface from weather satellites benefited from his skill both as a meteorologist and an astronomer. Most of his work was directed toward the goal of deducing vertical temperature and moisture profiles in the Earth's atmosphere, but he also proposed a method for obtaining cloud top altitudes using the oxygen A band. In the early days of this effort at NOAA/NESDIS and its predecessor agencies, Dr. Wark and others (most notably Dr. S. Fritz), assembled a remarkable group of internationally known scientists at NOAA to work on this pioneering effort and made Suitland, Maryland an exciting place to work. Included in this group of visiting scientists were G. Yamamoto, D. G. James, S. Twomey, and F. Saiedy. In addition to his own insights, Dr. Wark proved to have a remarkable facility for subdividing the complex temperature profiling problem into smaller component problems that the visiting and U.S. scientists could attack without interfering with each other. Despite his well-deserved reputation for having a formidable personality, he guided the development of the satellite temperature profiling field with tact, diplomacy, and scientific acumen. During this time, Dr. Wark also brought to NESDIS, and guided, a number of younger scientists who went on to establish reputations of their own in the fields of satellite remote sensing and satellite meteorology. These included J. Alishouse, L. Crone, D. Crosby, H. Fleming, H. Jacobowitz, L. McMillin, W. L. Smith, L. Stowe, and M. Weinreb. A Fellow of the American Meteorological Society, Dr. Wark received numerous awards from various scientific organizations, including a Silver Medal and a Gold Medal from the U.S. Department of Commerce, the Medal for Exceptional Scientific Achievement from NASA, the 2nd Half-Century Award from the American Meteorological Society, the Lloyd V. Berkner Space Utilization Award from the Americ

    Directory of Open Access Journals (Sweden)

    Paolo Sebastiano Lanzi

    2013-02-01

    Full Text Available L’opera di David Lynch non si limita al cinema, come ha dimostrato l’esposizione del 2007 alla Fondation Cartier di Parigi, The Air is on Fire. Tuttavia gli studi teorici hanno trascurato ciò che gallerie e musei hanno evidenziato da tempo: il Lynch pittore, fotografo, musicista, artista poliedrico. L’articolo si focalizza su una serie fotografica, Snowmen, ed è tratto da una ricerca di Paolo Sebastiano Lanzi sulla figura di David Lynch fotografo. Alla luce del saggio di Freud sul Perturbante (Das Unheimliche, 1919 si interpretano gli Snowmen come immagini di morte. Si chiariscono alcuni aspetti della poetica dell’artista-regista, come l’inquietudine dell’Inland Empire o di certe idee care al Surrealismo. Lo studio della produzione fotografica di Lynch riempie un vuoto nell’analisi critica sul suo lavoro, che va necessariamente riconsiderato in una prospettiva più ampia.

  5. David and the matriarch in the Book of Ruth

    Directory of Open Access Journals (Sweden)

    1994-06-01

    Full Text Available In this paper it is argued that the motif of the matriarch is not only present in the Book of Ruth, but that it also fulfils an important role. Several motifs and clusters of motifs established in the patriarchal narratives, especially that of the protection of the matriarch, are shown to be used in such a way that Ruth is portrayed as a typical matriarch. Since a matriarch is a matriarch by virtue of the importance of her offspring, the David motif in 4:17 is by no means secondary, but an inherent part of the narrative itself. This in turn has implications for the theological basis of the Davidic dynasty: Since the motif of the matriarch in this way becomes part of the royal theme, its meaning is determined by the overarching theme of solidarity and love, viz. that the royal house is founded not on 'pure' descent, but on solidarity and love.

  6. DAVID: A new video motion sensor for outdoor perimeter applications

    International Nuclear Information System (INIS)

    To be effective, a perimeter intrusion detection system must comprise both sensor and rapid assessment components. The use of closed circuit television (CCTV) to provide the rapid assessment capability, makes possible the use of video motion detection (VMD) processing as a system sensor component. Despite it's conceptual appeal, video motion detection has not been widely used in outdoor perimeter systems because of an inability to discriminate between genuine intrusions and numerous environmental effects such as cloud shadows, wind motion, reflections, precipitation, etc. The result has been an unacceptably high false alarm rate and operator work-load. DAVID (Digital Automatic Video Intrusion Detector) utilizes new digital signal processing techniques to achieve a dramatic improvement in discrimination performance thereby making video motion detection practical for outdoor applications. This paper begins with a discussion of the key considerations in implementing an outdoor video intrusion detection system, followed by a description of the DAVID design in light of these considerations

  18. Obituary: David Fulmer Bender, 1913-2004

    Science.gov (United States)

    Miller, Sylvia L.

    2004-12-01

    David Fulmer Bender died in San Diego, California, on 13 September 2004, at the age of 91. His heart stopped suddenly while he was dancing. His pioneering work in establishing comprehensive, computer-accessible ephemerides of asteroids and comets found many applications, including the first-ever visit to an asteroid, Gaspra, by an interplanetary spacecraft. Dave was born in Reno, Nevada, on 10 February 1913, to Homer Charles Bender and Susan Bowers Bender. The family moved to Spokane, Washington, while Dave was very young. His father was a civil engineer and a graduate of MIT, who helped design bridges and dams throughout the Northwest, including the Grand Coolie Dam. Dave had a brother, Phillip (now deceased), who was one year younger. Advancing rapidly in the Spokane school system, Dave finished high school when he was 15 years old. At 16 he moved to Pasadena, California, and began his studies at the California Institute of Technology (Caltech). In addition to pursuing his course work, he was active in track and football, a tendency toward physical exercise that stayed with him for the rest of his life. It was probably during these years that Dave heard a lecture by Albert Einstein, as mentioned to colleagues many years later. Dave received a BS degree in physics in 1933, an MS in 1934, and a PhD in 1937, all from Caltech. His dissertation was entitled, "The Index of Refraction of Air in the Photographic Infrared." During his sophomore year he found his way to Pomona College in Claremont, California, where he met his future wife, Elizabeth Boyden at a social gathering. They were married in 1935. Dave's academic career spanned the years from 1937 to 1970, initially at Louisiana State University, Vanderbilt University, and then Fisk. As a life-long pacifist and conscientious objector, Dave served alternate duty during World War II. In 1946 he joined the faculty of the physics department at Whittier College in California, where he became the department chair and remained until 1970. Here Dave's strong personal interest in the students became evident. During each year's spring break, he and Beth led a car caravan of interested astronomy and physics students to Death Valley for primitive camping, exploring the desert, studying the stars, and shooting off rockets. Beth organized all the food and Dave cooked the breakfasts, with French toast being his specialty. This tradition was so popular that many students returned year after year, long after having left the college. Dave enjoyed leading the astronomy club at Whittier College, and also participated in a municipal astronomy club. In the sixties, in addition to his job at the college, Dave worked part time at the Space Science Laboratory of North American Aviation (later North American Rockwell and now Boeing). Dave co-authored, with Gary Mc Cue and others, several papers on orbital rendezvous techniques, a capability of prime interest to the Apollo program. Soon apparent, however, was Dave's interest in the hundreds of asteroids whose orbits were known at the time. In his spare time he punched their orbital elements into computer cards and initiated a long career of searching for opportunities for spacecraft to flyby or rendezvous with one of these minor planets. He learned enough Russian to read books important at the time on the subject of asteroid orbits. In 1966 he had enough data to publish a paper on some possible asteroid encounters by human missions to Mars. Through conferences of the American Astronautical Society, Dave became acquainted with Roger Bourke, the group supervisor of the Advanced Projects Group at the Jet Propulsion Laboratory (JPL), which is managed by Caltech for NASA. In 1970, Dave retired from Whittier College and began working full time for Roger at JPL. JPL was still working on missions to the inner planets and was starting to develop missions to the outer planets. Roger understood the potential of having Dave pursue his interest in the small bodies and of having him create a comprehensive set of ephemerides that would be available for

This analysis helps better understand the role and place of experimental phenomena, it is emphasized that there are some insurmountable problems inherent in it - notably the impossibility to formulate the quantum theory of gravity on its basis - which prevent it from being a fundamental physical theory of the world of microscopic distances. It is this task, the creation of such a theory, which string theory, currently far from completion, is expected to solve. In spite of its somewhat vague current form, string theory has already led to a number of serious results and greatly contributed to progress in the understanding of quantum field theory. It is these developments, which are our concern in this review

    Full Text Available Considering the severe impacts of genetic bottlenecks and small numbers of founders in populations of reintroduced animals, it is necessary to study inbreeding and its effect on fitness in species of conservation concern. Père David’s deer is one of few large mammal species extinct in the wild but safely preserved in captivity. Its specific background gives us the opportunity to study the relationships between heterozygosity and neonatal fitness in relocated populations. We employed five microsatellite loci to explore heterozygosity-fitness correlations in a population of Père David’s deer at the Beijing Milu Ecological Research Center. We observed associations between microsatellite-based variables sMLH, IR, MD2 and HL, and two components of fitness expressed early in life (birth weight and the neonatal mortality of 123 Père David’s deer calves born over six consecutive years. We found that neonatal mortality was 19.1 ± 7.6%, not higher than the 19% or 18% reported in other ungulates. The heterozygosity of calves was not associated with neonatal mortality, nor birth weight. Our study implies that low genetic variability of microsatellite loci has no overt effect on birth weight and neonatal mortality in reintroduced populations of Père David’s deer [Current Zoology 59 (2: 249–256, 2013].

  3. Supergravity theories

    International Nuclear Information System (INIS)

    Of all supergravity theories, the maximal, i.e., N = 8 in 4-dimension or N = 1 in 11-dimension, theory should perform the unification since it owns the highest degree of symmetry. As to the N = 1 in d = 11 theory, it has been investigated how to compactify to the d = 4 theories. From the phenomenological point of view, local SUSY GUTs, i.e., N = 1 SUSY GUTs with soft breaking terms, have been studied from various angles. The structures of extended supergravity theories are less understood than those of N = 1 supergravity theories, and matter couplings in N = 2 extended supergravity theories are under investigation. The harmonic superspace was recently proposed which may be useful to investigate the quantum effects of extended supersymmetry and supergravity theories. As to the so-called Kaluza-Klein supergravity, there is another possibility. (Mori, K.)

    David Elijah Packer (1862-1936), a librarian by profession, was an enthusiastic amateur astronomer who observed from London and Birmingham. He first came to the attention of the astronomical community in 1890 when he discovered a variable star in the globular cluster M5, only the second periodic variable to be discovered in a globular cluster. He also observed meteors and nebulae, on one occasion reporting a brightening in the nucleus of the galaxy M77. However, his remarkable claims in 1896 that he had photographed the solar corona in daylight were soon shown to be flawed.

    The attitudes of 211 students at a university in Mississippi were investigated both before and after seeing the Public Broadcasting Film Who Is David Duke? The film provided evidence of Duke's current racism, anti-Semitism, and pro-Nazi leanings. In a previous study with university students in Louisiana, the majority did not change their attitudes after watching the film (Eisenman, 1993). However, in the present study, students' attitudes showed change in an anti-Duke direction. The findings are discussed and reasons given for the differences between the two samples, and for the popularity of Duke, a former leader of the Ku Klux Klan. PMID:8237541

    2009-09-01

    Shortly after AGU launched its annual voluntary contribution campaign last year—the theme was “Building Tomorrow's Talent Today”—the Union's development office received an e-mail message from David E. Lumley about establishing a scholarship for a high-school student or undergraduate. Many scientific societies and associations have quite a few named scholarships, but for AGU this was a new concept. Lumley was sure of what he wanted to do and even more excited when he learned that his scholarship would be a first for AGU. “I want to help inspire today's young minds to work on problems of global importance in both the energy and environment sectors of industry and academia,” Lumley said. Recipients of the David E. Lumley Young Scientist Scholarship for Energy and Environmental Science will be expected to present a paper and to participate in various student activities at Fall Meeting. “Meeting some of the ‘giants’ of geoscience and getting their feedback on research is a big deal for these young students. We sometimes lose sight of this,” he said.

  13. David of the Psalters: MT Psalter, LXX Psalter and 11QPsª Psalter

    Scientific Electronic Library Online (English)

    Hulisani, Ramantswana.

    Full Text Available The focus of this paper is on the Davidic figure as presented in the Psalters-the MT Psalter, LXX Psalter and 11QPsª Psalter. David of the MT Psalter is the same figure we encounter in the LXX Psalter and 11QPsª Psalter; however, it is David as he is remembered uniquely in each of the Editorial Vari [...] ant Texts. The MT Psalter is compared with the LXX Psalter and 11QPsª Psalter. Contra Wilson, who argues that the MT Psalter deemphasises David when compared to the other textual witnesses, I argue that the MT Psalter is also susceptible to be read as a highly Davidic book. David is an important character in the Psalter and is the last of Israel's legendary figures mentioned within the bodies of the psalms. In the final analysis, the MT Psalter concludes with David, the sweet psalmist of Israel, remembered for directing Israel in the worship of Yahweh through unconditional praise, a praise resounding from every corner of the cosmos, Yahweh's temple.

    Volume 2: Superstring Theory and Beyond, begins with an introduction to supersymmetric string theories and goes on to a broad presentation of the important advances of recent years. The book first introduces the type I, type II, and heterotic superstring theories and their interactions. It then goes on to present important recent discoveries about strongly coupled strings, beginning with a detailed treatment of D-branes and their dynamics, and covering string duality, M-theory, and black hole entropy, and discusses many classic results in conformal field theory. The final four chapters are concerned with four-dimensional string theories, and have two goals: to show how some of the simplest string models connect with previous ideas for unifying the Standard Model; and to collect many important and beautiful general results on world-sheet and spacetime symmetries.

    2014-01-01

    A general account of MOND theory is given. I start with the basic tenets of MOND, which posit departure from standard dynamics in the limit of low acceleration -- below an acceleration constant a0 -- where dynamics become scale invariant. I list some of the salient predictions of these tenets. The special role of a0 and its significance are then discussed. In particular, I stress its coincidence with cosmologically relevant accelerations. The deep-MOND limit and the consequences of its scale invariance are considered in some detail. General aspects of MOND theories are then described, after which I list briefly presently known theories, both nonrelativistic and relativistic. Most full-fledged theories modify the gravitational action, hinge on a0, introduce an interpolating function between the low and high accelerations, and obey MOND requirements in the opposite limits. These theories have much heuristic value as proofs of various concepts (e.g., that covariant MOND theories can be written with correct gravi...

  1. Nineteenth-century inhibitory theories of thinking: Bain, Ferrier, Freud (and Phineas Gage).

    Science.gov (United States)

    Macmillan, M

    2000-08-01

    The theories of thinking of Alexander Bain, David Ferrier, and Sigmund Freud are examined and their relation to Phineas Gage explored. During the 19th century Ferrier derived an inhibitory-motor theory of thinking from a similar theory of Bain's, and aspects of Freud's theory of thinking resemble both. All 3 theories were modeled on the sensory-motor reflex, and all proposed that thinking was inhibited action. Ferrier used his theory to explain the behavior of monkeys whose frontal lobes were ablated and the disinhibited behavior Phineas Gage exhibited after massive damage to his frontal lobes. I show there is some possibility that Freud knew the Bain-Ferrier theory of thinking and its application to Gage. PMID:11624593

    Since discovery of the Jones polynomial, knot theory has enjoyed a virtual explosion of important results and now plays a significant role in modern mathematics. In a unique presentation with contents not found in any other monograph, Knot Theory describes, with full proofs, the main concepts and the latest investigations in the field.The book is divided into six thematic sections. The first part discusses "pre-Vassiliev" knot theory, from knot arithmetics through the Jones polynomial and the famous Kauffman-Murasugi theorem. The second part explores braid theory, including braids in different spaces and simple word recognition algorithms. A section devoted to the Vassiliev knot invariants follows, wherein the author proves that Vassiliev invariants are stronger than all polynomial invariants and introduces Bar-Natan''s theory on Lie algebra respresentations and knots.The fourth part describes a new way, proposed by the author, to encode knots by d-diagrams.

  4. Uncertainty theory

    CERN Document Server

    Liu, Baoding

    2015-01-01

    When no samples are available to estimate a probability distribution, we have to invite some domain experts to evaluate the belief degree that each event will happen. Perhaps some people think that the belief degree should be modeled by subjective probability or fuzzy set theory. However, it is usually inappropriate because both of them may lead to counterintuitive results in this case. In order to rationally deal with belief degrees, uncertainty theory was founded in 2007 and subsequently studied by many researchers. Nowadays, uncertainty theory has become a branch of axiomatic mathematics for modeling belief degrees. This is an introductory textbook on uncertainty theory, uncertain programming, uncertain statistics, uncertain risk analysis, uncertain reliability analysis, uncertain set, uncertain logic, uncertain inference, uncertain process, uncertain calculus, and uncertain differential equation. This textbook also shows applications of uncertainty theory to scheduling, logistics, networks, data mining, c...

    Full Text Available The aim of this article is to study the fictional and metafictional approach of David Lodge who has deeply influenced not only the recent English literature but also the West literature. As a literature professor, theorist, critic and fiction writer, Lodge has a different stand from most other authors. These characteristics are easily recognized with the metafictional techniques and methods used in his fictions. Lodge makes the occupation of fiction be the focus material of fiction. Because he both carries different identities and works carefully on fiction, he has become a writer drawing attention to fiction and metafiction. He has constantly renewed his literary experience and followed a way open to various tendencies and techniques. Therefore, watching Lodge’s literary line will also set light on the modern-day literary understanding.

  14. David Duke, running for governor, proposes tattooing people with HIV.

    Science.gov (United States)

    1995-05-19

    Former Ku Klux Klan leader, David Duke, planning a second run for governor of Louisiana, said he would curb the AIDS epidemic by tattooing people who are infected with HIV. His suggestion is to put indelible, glow-in-the-dark tattoos on the genitals of people infected with HIV. According to Duke, it may sound very draconian but it would not demean people. He also believes that tattooing would be legal because courts have a history of supporting the quarantining and institutionalizing of people with infectious diseases, such as tuberculosis. Duke said Cuba has had some success in using quarantines to reduce HIV infection, but he does not think it would work in the United States because it would cost too much. According to Duke, many people who get HIV from irresponsible behavior do not tell their partners that they have AIDS--these people are mad at the world and engage in dangerous behaviors even more.

    Agency theory studies the problems and solutions linked to delegation of tasks from principals to agents in the context of conflicting interests between the parties. Beginning from clear assumptions about rationality, contracting, and informational conditions, the theory addresses problems of ex ante (‘hidden characteristics’) as well as ex post information asymmetry (‘hidden action’), and examines conditions under which various kinds of incentive instruments and monitoring arrangements can be deployed to minimize the welfare loss. Its clear predictions and broad applicability have allowed agency theory to enjoy considerable scientific impact on social science; however, it has also attracted considerable criticism.

    2015-05-01

    Full Text Available The purpose of this paper is to compare probability theory with possibility theory, and to use this comparison in comparing probability theory with fuzzy set theory. The best way of comparing probabilistic and possibilistic conceptualizations of uncertainty is to examine the two theories from a broader perspective. Such a perspective is offered by evidence theory, within which probability theory and possibility theory are recognized as special branches. While the various characteristic of possibility theory within the broader framework of evidence theory are expounded in this paper, we need to introduce their probabilistic counterparts to facilitate our discussion.

    International Nuclear Information System (INIS)

    Several detailed models have been proposed in the last few years in an attempt to unify weak and electromagnetic interactions, using gauge theories. These are based on a renormalisable field theory. An attempt is made to outline the patterns that have emerged from these models. The interesting point is that the various requirements of weak, and electromagnetic interactions along with some restrictions needed for strong interactions seem to lead to a broad picture of strong interactions. The results are analysed and reviewed. (K.B.)

    Ian Stewart's Galois Theory has been in print for 30 years. Resoundingly popular, it still serves its purpose exceedingly well. Yet mathematics education has changed considerably since 1973, when theory took precedence over examples, and the time has come to bring this presentation in line with more modern approaches.To this end, the story now begins with polynomials over the complex numbers, and the central quest is to understand when such polynomials have solutions that can be expressed by radicals. Reorganization of the material places the concrete before the abstract, thus motivating the g

  3. Effective theories of universal theories

    CERN Document Server

    Wells, James D

    2015-01-01

    It is well-known but sometimes overlooked that constraints on the oblique parameters (most notably $S$ and $T$ parameters) are only applicable to a special class of new physics scenarios known as universal theories. In the effective field theory (EFT) framework, the oblique parameters should not be associated with Wilson coefficients in a particular operator basis, unless restrictions have been imposed on the EFT so that it describes universal theories. We work out these restrictions, and present a detailed EFT analysis of universal theories. We find that at the dimension-6 level, universal theories are completely characterized by 16 parameters. They are conveniently chosen to be: 5 oblique parameters that agree with the commonly-adopted ones, 4 anomalous triple-gauge couplings, 3 rescaling factors for the $h^3$, $hff$, $hVV$ vertices, 3 parameters for $hVV$ vertices absent in the Standard Model, and 1 four-fermion coupling of order $y_f^2$. All these parameters are defined in an unambiguous and basis-indepen...

  7. Nuclear theory

    International Nuclear Information System (INIS)

    The present volume is the last in a series of three. It opens with a discussion of the two-and three-nucleon problems, as preparation for the development of an understanding of nuclear structure phenomena from the fundamental nucleon-nucleon interaction. It then develops the theory of infinite nuclear matter as an example of a problem whose goals limited, but which may in the near future be subject to rather complete and thorough-going solution starting from first principles. The treatment of realistic nuclei is begun with the particle-hole formalism and its applications. Partly, this is taken to typify many aspects of microscopic theories of nuclear structure; partly, it exhibits the special feature of collective behavior from a microscopic viewpoint, as evidenced in its description of giant resonance phenomena. Subsequently, microscopic theories of deformed light nuclei and their rotational properties are treated. Attention then shifts to concepts which are generally applied for microscopic treatments of heavier nuclei, notably pairing seniority and the quasi-particle transformation. These ideas are applied in some detail to the microscopic construction of collective potential energy surfaces and of the inertial parameters of collective motion. Lastly, two appendices are included, one on projection methods and one on the use of collective coordinates in a microscopic theory

    Full Text Available The American Dream is a recurrent theme in American literature. In this response, this paper is an attempt to expose the destructive effects of the dream on human spirits and relations and how it is contradicted in different ways through the analysis of his brilliant play, American Buffalo by David Mamet. Beneath the seeming simple surface of the play lies a deep current of meanings that reflect the calamities of modern American life, and in a broader sense, the modern world. This article indicates how capitalism inculcates ideologies in the mind of individuals in order to facilitate the exploiting process and unquestioning subordination. Ragged individualism, as one of these ideologies, disrupts all communal bonds and even exceeds to the disintegration of friendship and family life. On the other hand, this individualism, as an ideology, is sustained by other capitalist ideologies such as advertising, consumerism and emulation. It will also be discussed that monetary interests are all one seeks in a highly competitive atmosphere and nothing is privileged over business ethics. In brief, this reading of the play tries to illuminate that we live in a dream-like world of ideologies that block logical thinking and forge our relationship with our real existence through less suspected ways.Keywords: American Dream, Ideology, Capitalism, Individualism, Consumerism

    2014-11-01

    Full Text Available In a filmmaking career replete with extraordinary images and sounds, David Lynch's Mulholland Drive (2001 stands out for attention as a striking and seemingly inexhaustible resource for analysis. In this article, this film is used to examine the specific ways in which Lynch uses pre-existing pop songs to wrap the spectator within the filmic soundscape. Nowhere is the complexity and uncanniness of pop music made more explicit than in Rebekah Del Rio's stunning performance of “Llorando (Crying” in the Club Silencio scene. The split between the singer's powerful performance and her subsequent collapse with the sound of the voice left hanging in the air marks a pivotal point in the film. This scene, coupled with other examples of feminine jouissance, is contrasted with the deadening roar of the master's voice, which solely demands obedience but is deaf to any reply. At the core of this article is an analysis of the status of the voice (and the gaze as examples of the Lacanian object a and its relationship to Marx's concept of surplus value. Mulholland Drive provides a powerful demonstration of how these concepts can be seen, heard, and felt in relation to film, and how sound can reverberate into the spaces and silences beyond the screen.

    1995-01-01

    The comprehensive integration and environmental (including RF) test facilities of the Canadian Space Agency's David Florida Laboratory (CSA)(DFL) were used extensively for the MSAT Program. Following a description of the facilities, the paper outlines their application to the qualification of the two MSAT satellites following an overview of the test plan. Particular emphasis is given to passive intermodulation measurement (PIM) demands, which for the MSAT satellites, contributed to the need to extend the anechoic chamber. The extended chamber was also used for an EMC test and SAR signature test of the RADARSAT satellite. The DFL's facilities are being used for additional aspects of mobile satellite communications. One shielded anechoic Extra High Frequency (EHF) chamber and associated test equipment are employed predominantly for measuring the performance of the IRIDIUM satellites' Engineering Model Gateway Moveable Antennas (EM)(GMA). Other chambers are used for testing aeronautical antennas on behalf of Inmarsat. Still others combine thermal and PIM testing. The paper concludes with a review of the test requirements of evolving satcom missions such as Inmarsat Aero-1.

  13. David Hartley's psychobiological associationism and the legacy of Aristotle.

    Science.gov (United States)

    Buckingham, H W; Finger, S

    1997-04-01

    The idea that there are certain "laws" of learning (similarity, contrast, contiguity) can be traced to Aristotle. He maintained that external stimuli cause small movements in the vessels to the dominant heart, the vestiges of which can be linked to one another. Aristotle's laws of learning were incorporated into the writings of Hobbes, Locke, and Berkeley, men who said nothing about the physiological correlates of mental associations. This left the door open for David Hartley to combine mental associationism with the Newtonian idea that sensations can cause minute particle vibrations in the nerves. Hartley's amalgam of psychology, philosophy, and neurology was first presented in 1746, as a "trial balloon" at the end a little-known monograph on a treatment for kidney stones. It was repeated three years later in his better-known Observations on Man. In many ways, modern psychobiological connectionism can be traced back to Hartley's Conjectures of 1746, in which Aristotle's original thoughts were modified with then current ideas about functions of the mind and the nervous system.

    Directory of Open Access Journals (Sweden)

    Golimowska, Karolina

    2012-01-01

    Full Text Available This article addresses the transatlantic relations between the United States and Europe and specifically Great Britain in the context of post-9/11 international politics as reflected in the drama Stuff Happens (2004 written by British playwright David Hare. It focuses on the way re­cent history is performed and contextualized in dramatic form and analyzes the function and power of the theatricalization of historic events and particularly of finding ways to address 9/11 on a stage. Furthermore, it discusses the method of mixing parts of public speeches quoted ver­batim with fiction and its effects on readers and audiences. The play addresses the struggles and fragility of international diplomacy in the aftermath of 9/11. It reflects a general skepticism to­wards politicians and their decisions as well as the helpless position of millions of observers who are affected by these decisions and yet feel like they have no influence. This article sees post-9/11 verbatim theater as a chance for playwright and spectators to get access to the world of politics and to take part in the process of writing transatlantic history. More generally, through the ex­ample of this play, the article aims at discussing new challenges and functions of post-9/11 theater.

  15. Information Theory, Inference and Learning Algorithms

    Science.gov (United States)

    Mackay, David J. C.

    2003-10-01

    Information theory and inference, often taught separately, are here united in one entertaining textbook. These topics lie at the heart of many exciting areas of contemporary science and engineering - communication, signal processing, data mining, machine learning, pattern recognition, computational neuroscience, bioinformatics, and cryptography. This textbook introduces theory in tandem with applications. Information theory is taught alongside practical communication systems, such as arithmetic coding for data compression and sparse-graph codes for error-correction. A toolbox of inference techniques, including message-passing algorithms, Monte Carlo methods, and variational approximations, are developed alongside applications of these tools to clustering, convolutional codes, independent component analysis, and neural networks. The final part of the book describes the state of the art in error-correcting codes, including low-density parity-check codes, turbo codes, and digital fountain codes -- the twenty-first century standards for satellite communications, disk drives, and data broadcast. Richly illustrated, filled with worked examples and over 400 exercises, some with detailed solutions, David MacKay's groundbreaking book is ideal for self-learning and for undergraduate or graduate courses. Interludes on crosswords, evolution, and sex provide entertainment along the way. In sum, this is a textbook on information, communication, and coding for a new generation of students, and an unparalleled entry point into these subjects for professionals in areas as diverse as computational biology, financial engineering, and machine learning.

    Hashiguchi, Koichi

    2014-01-01

    This book was written to serve as the standard textbook of elastoplasticity for students, engineers and researchers in the field of applied mechanics. The present second edition is improved thoroughly from the first edition by selecting the standard theories from various formulations and models, which are required to study the essentials of elastoplasticity steadily and effectively and will remain universally in the history of elastoplasticity. It opens with an explanation of vector-tensor analysis and continuum mechanics as a foundation to study elastoplasticity theory, extending over various strain and stress tensors and their rates. Subsequently, constitutive equations of elastoplastic and viscoplastic deformations for monotonic, cyclic and non-proportional loading behavior in a general rate and their applications to metals and soils are described in detail, and constitutive equations of friction behavior between solids and its application to the prediction of stick-slip phenomena are delineated. In additi...

  17. Operator theory

    CERN Document Server

    2015-01-01

    A one-sentence definition of operator theory could be: The study of (linear) continuous operations between topological vector spaces, these being in general (but not exclusively) Fréchet, Banach, or Hilbert spaces (or their duals). Operator theory is thus a very wide field, with numerous facets, both applied and theoretical. There are deep connections with complex analysis, functional analysis, mathematical physics, and electrical engineering, to name a few. Fascinating new applications and directions regularly appear, such as operator spaces, free probability, and applications to Clifford analysis. In our choice of the sections, we tried to reflect this diversity. This is a dynamic ongoing project, and more sections are planned, to complete the picture. We hope you enjoy the reading, and profit from this endeavor.

    Stein, Irene F.; Stelter, Reinhard

    2011-01-01

    Communication theory covers a wide variety of theories related to the communication process (Littlejohn, 1999). Communication is not simply an exchange of information, in which we have a sender and a receiver. This very technical concept of communication is clearly outdated; a human being is not a data processing device. In this chapter, communication is understood as a process of shared meaning-making (Bruner, 1990). Human beings interpret their environment, other people, and themselves on the basis of their dynamic interaction with the surrounding world. Meaning is essential because people ascribe specific meanings to their experiences, their actions in life or work, and their interactions. Meaning is reshaped, adapted, and transformed in every communication encounter. Furthermore, meaning is cocreated in dialogues or in communities of practice, such as in teams at a workplace or in school classes (Stelter, 2007).

It offers a distinctive way of thinking about the human mind and of responding to psychological distress.

    2016-01-01

    This corrected and updated second edition of "Scattering Theory" presents a concise and modern coverage of the subject. In the present treatment, special attention is given to the role played by the long-range behaviour of the projectile-target interaction, and a theory is developed, which is well suited to describe near-threshold bound and continuum states in realistic binary systems such as diatomic molecules or molecular ions. It is motivated by the fact that experimental advances have shifted and broadened the scope of applications where concepts from scattering theory are used, e.g. to the field of ultracold atoms and molecules, which has been experiencing enormous growth in recent years, largely triggered by the successful realization of Bose-Einstein condensates of dilute atomic gases in 1995. The book contains sections on special topics such as near-threshold quantization, quantum reflection, Feshbach resonances and the quantum description of scattering in two dimensions. The level of abstraction is k...

  5. Urban common space, heterotopia and the right to the city: Reflections on the ideas of Henri Lefebvre and David Harvey

    Directory of Open Access Journals (Sweden)

    Orlando Alves dos Santos Junior

    2014-05-01

    Full Text Available A city?s common spaces are appropriated by capital that aims to guarantee the conditions necessary for the production-reproduction of capitalist relations. In this context, the challenge is to imagine and construct a very different type of city capable of breaking away from the dynamic of capital, founded on new forms of appropriation of the city, which implies articulating both theory and praxis. For this to occur, however, it is necessary to create new knowledge about the city and a strong anti-capitalist social movement focused on the transformation of daily urban life and involving new forms of appropriation of urban common spaces. It is in this context, and from a dialectic perspective, that this article articulates the ideas of Henri Lefebvre and David Harvey, seeking to contribute to an understanding of the production processes of space in contemporary capitalism, the discussion of the future of cities and perspectives on transition. To do so, the article addresses four central ideas: (i the dialectic conception of space to problematize the production and appropriation of urban common spaces; (ii the recognition of urban common spaces as spaces traversed by contradictions, disputes and material and symbolic conflicts among different agents; (iii the right to the city as a need and as a utopian project; and (iv the challenge of articulating heterotopic practices from the perspective of creative rebellion for the right to the city and the transition to a new urban future.

    The rise of personal computer challenged mainframes systems for automation of existing work routine. Furthermore it brought forth a need to focus on how to work on materials and objects through the computer. In search for theoretical and methodical perspectives it seemed promising to turn towards the young HCI research tradition. But HCI was already facing problems: lack of consideration for other aspects of human behavior, for interaction with other people, for culture. Cognitive science-based theories lacked means to address several issues that came out of the empirical projects.

  6. Sustainablegrowth theories

    International Nuclear Information System (INIS)

    With reference to highly debated sustainable growth strategies to counter pressing interrelated global environmental and socio-economic problems, this paper reviews economic and resource development theories proposed by classical and neoclassical economists. The review evidences the growing debate among public administration decision makers regarding appropriate methods to assess the worth of natural resources and ecosystems. Proposed methods tend to be biased either towards environmental protection or economic development. Two major difficulties in the effective implementation of sustainable growth strategies are also evidenced - the management of such strategies would require appropriate revisions to national accounting systems, and the dynamic flow of energy and materials between an economic system and the environment would generate a sequence of unstable structures evolving in a chaotic and unpredictable way

    We will see that key concepts of number theory can be defined for arbitrary operations. We give a generalized distributivity for hyperoperations (usual arithmetic operations and operations going beyond exponentiation) and a generalization of the fundamental theorem of arithmetic for hyperoperations. We also give a generalized definition of the prime numbers that are associated to an arbitrary n-ary operation and take a few steps toward the development of its modulo arithmetic by investigating a generalized form of Fermat's little theorem. Those constructions give an interesting way to interpret diophantine equations and we will see that the uniqueness of factorization under an arbitrary operation can be linked with the Riemann zeta function. This language of generalized primes and composites can be used to restate and extend certain problems such as the Goldbach conjecture.

    Full Text Available This study attempts to provide a theoretical framework for the corporate governance debate. The review of various corporate governance theories enhances the major objective of corporate governance which is maximizing the value for shareholders by ensuring good social and environment performances. The theories of corporate governance are rooted in agency theory with the theory of moral hazard’s implications, further developing within stewardship theory and stakeholder theory and evolving at resource dependence theory, transaction cost theory and political theory. Later, to these theories was added ethics theory, information asymmetry theory or the theory of efficient markets. These theories are defined based on the causes and effects of variables such as: the configuration of the board of directors, audit committee, independence of managers, the role of top management and their social relations beyond the legal regulatory framework. Effective corporate governance requires applying a combination

  9. Seyed Mohammad Hossein Tabatabai and David Hume in the philosophical basis for determining the values

    Directory of Open Access Journals (Sweden)

    Mohammad Javad Movahedi

    Full Text Available allameh sayyid muhammad husain tabatabaei and David Hume, in regard to influential philosophical thought's, are very important, one in the Muslim world and The other in the West world. Allama has mentioned his thoughts on ethics, in his two books, the principles of philosophy and Method of realism and Al-Mizan interpretation (Quranic exegesis. In The principles of philosophy and Method of realism, his main discussions are actions that export from agent and the relationship between agent and action. In the sixth chapter of the book, Allama generally analyzes mental aspects, and in particular, examines the psychophilosophical analysis and epistemology of the moral concepts. In terms of epistemology, ethics is one of the perceptions of mental aspects, and according to Allama, humans naturally can distinct right from wrong and take steps towards goodness and happiness. The second psychophilosophical aspect of ethics is related to good moral qualities and spiritual positive properties. As was stated before, humans, by nature, are equipped with the ability to recognize right and wrong; so it can be concluded in the issue of good moral qualities and spiritual positive properties, that virtues and vices are in the form of spiritual positive properties and that actualized in regard to need of Physical actions, and accordingly, humans are forced to take action. Allama in epistemological discussions and how human can obtain the knowledge has analyzed the agency of human and relationship between the agent and the action with the aim of demonstrating the role of reason and perceptions in all levels of human life as central and substantial.Hume at the beginning of the third book, a treatise on human nature, stated that "Morality is a subject that interests us above all others"; He spoke of the importance of this field of philosophy. You can even ponder and reflect on the previous parts of the book so that the introductions of a scheme of ethics are discussed. Hume's moral philosophy can be considered as "virtue-based ethics". The main concepts of his ethical theory are such as Behavior, virtues and vices, and not a duty, maxims and obligation. The salient feature of Hume's moral theory is the emphasis upon moral sense according which we discern vicious and virtuous behavior. Consequently, according to Taylor, "Hume's ethics can be contrasted with other forms of virtue-based ethics, such as Aristotelian ethics." In Aristotelian virtue ethics, the focus is on the virtuous agent, and to investigate how people can be involved in the acquisition of virtues and deals with the role of virtue in having a good and calm life; whereas Hume is merely deals with diagnoses and assess the treatment. Most of his work is behavior cognition, and partly psychological and is based on an act-centered attitude. His attitude of moral knowledge based on good and bad behaviors of people is distinguished and evaluated on the context of society and the dialogue and discussion. In other words, evaluation and recognition of the moral norms of virtues- or vices-based is a social practice and the social conditions make it clear. Accordingly, Hume argues that "passions as hate, anger, respect, love, courage, pain and pleasure, all of them bring from the communication with others within the community and not from my natural mood." As a result, one can say that the Allameh Tabatabai argues that human, by nature, has the ability to distinguish right from wrong, and therefore, there are virtues and vices in the form of spiritual positive properties and that actualized in regard to need of Physical actions, and accordingly, humans are forced to take action. Then, human with using the power of "wisdom", can distinguish between virtues and vices. However, Hume explicitly does not consider distinguishing between good and evil as the act of reason, but of "moral sense", and According to him, "reason is the slave of the passions

  13. DAVID Knowledgebase: a gene-centered database integrating heterogeneous gene annotation resources to facilitate high-throughput gene functional analysis

    Directory of Open Access Journals (Sweden)

    Baseler Michael W

    2007-11-01

    Full Text Available Abstract Background Due to the complex and distributed nature of biological research, our current biological knowledge is spread over many redundant annotation databases maintained by many independent groups. Analysts usually need to visit many of these bioinformatics databases in order to integrate comprehensive annotation information for their genes, which becomes one of the bottlenecks, particularly for the analytic task associated with a large gene list. Thus, a highly centralized and ready-to-use gene-annotation knowledgebase is in demand for high throughput gene functional analysis. Description The DAVID Knowledgebase is built around the DAVID Gene Concept, a single-linkage method to agglomerate tens of millions of gene/protein identifiers from a variety of public genomic resources into DAVID gene clusters. The grouping of such identifiers improves the cross-reference capability, particularly across NCBI and UniProt systems, enabling more than 40 publicly available functional annotation sources to be comprehensively integrated and centralized by the DAVID gene clusters. The simple, pair-wise, text format files which make up the DAVID Knowledgebase are freely downloadable for various data analysis uses. In addition, a well organized web interface allows users to query different types of heterogeneous annotations in a high-throughput manner. Conclusion The DAVID Knowledgebase is designed to facilitate high throughput gene functional analysis. For a given gene list, it not only provides the quick accessibility to a wide range of heterogeneous annotation data in a centralized location, but also enriches the level of biological information for an individual gene. Moreover, the entire DAVID Knowledgebase is freely downloadable or searchable at http://david.abcc.ncifcrf.gov/knowledgebase/.

    Superstring theory, and a recent extension called M theory, are leading candidates for a quantum theory that unifies gravity with the other forces. As such, they are certainly not ordinary quantum field theories. However, recent duality conjectures suggest that a more complete definition of these theories can be provided by the large N limits of suitably chosen U(N) gauge theories associated to the asymptotic boundary of spacetime.

    Full Text Available The house of Eli and the house of David: how God can go back on God,s word. The interpretation of the rejection of Abiathar in terms of the Eli tradition offers an important indication of the intention of the Succession Narrative. The work does not only have a positive as well as a negative tendency as far as the Davidic dynasty is concerned, but the relationship between these two sides is one of conditionality. Therefore the critical aspect of the Succession Narrative contains both acceptance and warning. A sketch of the broader theological framework is given in which the interplay of God's love and his demand of obedience is understood in its historical context, including the redactional perspective.

    Charles Dickens’s David Copperfield abounds with fatherless and motherless children, whose development into adolescence and adulthood is strongly affected by the parenting skills of the remaining parent. This essay studies different parenting and educational practices in the novel to see their impact on the behaviour and personality of the children. In Victorian England, two opposing views of childhood flourished: the Puritan one believing in childhood depravity, and the Romantic view based o...

    Taking Anne Friedberg's notion of the post-perspectival as the point of departure for her analysis of David Lynch's digitally shot and edited Inland Empire from 2006, Anne Jerslev argues that the film deconstructs continuous time and coherent space by constructing multiple planes of representation, multiple layerings of screens and, hence, multiple and fractured modes of perception. The article further suggests that the film's enigmatic structure might best be understood ...

    2011-01-01

    In David Copperfield, Mr. Dick has played a diversity of roles. He serves not only as a comic figure who brings absurdity and laughter to these harsh experiences, a representative of innocence in disguise of a mentally disabled man, but also as a necessary mental counselor and a domestic helper to others. By exploring those roles to their fullest Charles Dickens has created a unique character that is enchanting as well as complicated.

  12. Boundary conformal field theories on random surfaces and the non-critical open string

    CERN Document Server

    Mansfield, P; Mansfield, Paul; Neves, Rui

    1996-01-01

    We analyse boundary conformal field theories on random surfaces using the conformal gauge approach of David, Distler and Kawai. The crucial point is the choice of boundary conditions on the Liouville field. We discuss the Weyl anomaly cancellation for Polyakov`s non-critical open bosonic string with Neumann, Dirichlet and free boundary conditions. Dirichlet boundary conditions are found to be unacceptable. We consider the semi-classical limit and argue how it singles out the free boundary conditions for the Liouville field. We define the open string susceptibility, the anomalous scaling dimensions and a new Yang-Mills Feynman mass critical exponent.

    A century ago, Georg Cantor demonstrated the possibility of a series of transfinite infinite numbers. His methods, unorthodox for the time, enabled him to derive theorems that established a mathematical reality for a hierarchy of infinities. Cantor's innovation was opposed, and ignored, by the establishment; years later, the value of his work was recognized and appreciated as a landmark in mathematical thought, forming the beginning of set theory and the foundation for most of contemporary mathematics. As Cantor's sometime collaborator, David Hilbert, remarked, ""No one will drive us from the

  14. Local homotopy theory

    CERN Document Server

    Jardine, John F

    2015-01-01

    This monograph on the homotopy theory of topologized diagrams of spaces and spectra gives an expert account of a subject at the foundation of motivic homotopy theory and the theory of topological modular forms in stable homotopy theory. Beginning with an introduction to the homotopy theory of simplicial sets and topos theory, the book covers core topics such as the unstable homotopy theory of simplicial presheaves and sheaves, localized theories, cocycles, descent theory, non-abelian cohomology, stacks, and local stable homotopy theory. A detailed treatment of the formalism of the subject is interwoven with explanations of the motivation, development, and nuances of ideas and results. The coherence of the abstract theory is elucidated through the use of widely applicable tools, such as Barr's theorem on Boolean localization, model structures on the category of simplicial presheaves on a site, and cocycle categories. A wealth of concrete examples convey the vitality and importance of the subject in topology, n...

  15. Microevolutionary, macroevolutionary, ecological and taxonomical implications of punctuational theories of adaptive evolution

    Directory of Open Access Journals (Sweden)

    Flegr Jaroslav

    2013-01-01

    Full Text Available Abstract Punctuational theories of evolution suggest that adaptive evolution proceeds mostly, or even entirely, in the distinct periods of existence of a particular species. The mechanisms of this punctuated nature of evolution suggested by the various theories differ. Therefore the predictions of particular theories concerning various evolutionary phenomena also differ. Punctuational theories can be subdivided into five classes, which differ in their mechanism and their evolutionary and ecological implications. For example, the transilience model of Templeton (class III, genetic revolution model of Mayr (class IV or the frozen plasticity theory of Flegr (class V, suggests that adaptive evolution in sexual species is operative shortly after the emergence of a species by peripatric speciation – while it is evolutionary plastic. To a major degree, i.e. throughout 98-99% of their existence, sexual species are evolutionarily frozen (class III or elastic (class IV and V on a microevolutionary time scale and evolutionarily frozen on a macroevolutionary time scale and can only wait for extinction, or the highly improbable return of a population segment to the plastic state due to peripatric speciation. The punctuational theories have many evolutionary and ecological implications. Most of these predictions could be tested empirically, and should be analyzed in greater depth theoretically. The punctuational theories offer many new predictions that need to be tested, but also provide explanations for a much broader spectrum of known biological phenomena than classical gradualistic evolutionary theories.

  16. Rationality, Theory Acceptance and Decision Theory

    Directory of Open Access Journals (Sweden)

    J. Nicolas Kaufmann

    1998-06-01

    Full Text Available Following Kuhn's main thesis according to which theory revision and acceptance is always paradigm relative, I propose to outline some possible consequences of such a view. First, asking the question in what sense Bayesian decision theory could serve as the appropriate (normative theory of rationality examined from the point of view of the epistemology of theory acceptance, I argue that Bayesianism leads to a narrow conception of theory acceptance. Second, regarding the different types of theory revision, i.e. expansion, contraction, replacement and residuals shifts, I extract from Kuhn's view a series of indications showing that theory replacement cannot be rationalized within the framework of Bayesian decision theory, not even within a more sophisticated version of that model. Third, and finally, I will point to the need for a more comprehensive model of rationality than the Bayesian expected utility maximization model, the need for a model which could better deal with the different aspects of theory replacement. I will show that Kuhn's distinction between normal and revolutionary science gives us several hints for a more adequate theory of rationality in science. I will also show that Kuhn is not in a position to fully articulate his main ideas and that he well be confronted with a serious problem concerning collective choice of a paradigm.

  18. Tractability of Theory Patching

    CERN Document Server

    Argamon-Engelson, S

    1998-01-01

    In this paper we consider the problem of `theory patching', in which we are given a domain theory, some of whose components are indicated to be possibly flawed, and a set of labeled training examples for the domain concept. The theory patching problem is to revise only the indicated components of the theory, such that the resulting theory correctly classifies all the training examples. Theory patching is thus a type of theory revision in which revisions are made to individual components of the theory. Our concern in this paper is to determine for which classes of logical domain theories the theory patching problem is tractable. We consider both propositional and first-order domain theories, and show that the theory patching problem is equivalent to that of determining what information contained in a theory is `stable' regardless of what revisions might be performed to the theory. We show that determining stability is tractable if the input theory satisfies two conditions: that revisions to each theory compone...

  3. Polite Theories Revisited

    Science.gov (United States)

    Jovanovi?, Dejan; Barrett, Clark

    The classic method of Nelson and Oppen for combining decision procedures requires the theories to be stably-infinite. Unfortunately, some important theories do not fall into this category (e.g. the theory of bit-vectors). To remedy this problem, previous work introduced the notion of polite theories. Polite theories can be combined with any other theory using an extension of the Nelson-Oppen approach. In this paper we revisit the notion of polite theories, fixing a subtle flaw in the original definition. We give a new combination theorem which specifies the degree to which politeness is preserved when combining polite theories. We also give conditions under which politeness is preserved when instantiating theories by identifying two sorts. These results lead to a more general variant of the theorem for combining multiple polite theories.

Darwin, on his turn, offers a graduation of many capacities of knowledge, distinguishing instinctive action from action resulting from deliberation and inference, and points to the fact that many animals have a significant degree of intelligent behavior. Darwinian mechanism of evolution by natural selection wants to explain this character, in humans as much as in animals. From that results the contemporary fashion in epistemology called evolutionary epistemology that, by following Darwin, lacks a more detailed interpretation of Hume's teaching that could, we suppose, offer elements to the treatment of questions such as the capacity of causal knowledge.

    We present a general framework for Matrix theory compactified on a quotient space R^n/G, with G a discrete group of Euclidean motions in R^n. The general solution to the quotient conditions gives a gauge theory on a noncommutative space. We characterize the resulting noncommutative gauge theory in terms of the twisted group algebra of G associated with a projective regular representation. Also we show how to extend our treatments to incorporate orientifolds.

Nesse contexto, o desafio seria imaginar e construir um tipo totalmente diferente de cidade capaz de romper com a dinâmica do capital, fund [...] ado em novas formas de apropriação da cidade, o que implica em articular teoria e práxis. Mas para isso ocorrer torna-se necessário criar um novo conhecimento sobre o urbano e um forte movimento social anticapitalista focado na transformação do cotidiano da vida urbana como seu objetivo, o que envolve novas formas de apropriação dos espaços urbanos comuns. É nesse contexto e desde uma perspectiva dialética que o presente ensaio busca articular as formulações de Henri Lefebvre e de David Harvey, buscando contribuir para a compreensão dos processos de produção do espaço no capitalismo contemporâneo, a discussão sobre o futuro das cidades e as perspectivas de transição. Para tanto, o ensaio aborda quatro ideias centrais: (i) uma concepção dialética de espaço para problematizar a produção e a apropriação dos espaços urbanos comuns da cidade; (ii) o reconhecimento dos espaços urbanos comuns das cidades como espaços atravessados por contradições, disputas e conflitos materiais e simbólicos entre diferentes agentes; (iii) o direito à cidade como uma necessidade e como um projeto utópico; e (iv) o desafio da articulação das práticas heterotópicas na perspectiva da rebeldia criativa pelo direito à cidade e da transição para novos futuros urbanos. Abstract in english A city's common spaces are appropriated by capital that aims to guarantee the conditions necessary for the production-reproduction of capitalist relations. In this context, the challenge is to imagine and construct a very different type of city capable of breaking away from the dynamic of capital, f [...] ounded on new forms of appropriation of the city, which implies articulating both theory and praxis. For this to occur, however, it is necessary to create new knowledge about the city and a strong anti-capitalist social movement focused on the transformation of daily urban life and involving new forms of appropriation of urban common spaces. It is in this context, and from a dialectic perspective, that this article articulates the ideas of Henri Lefebvre and David Harvey, seeking to contribute to an understanding of the production processes of space in contemporary capitalism, the discussion of the future of cities and perspectives on transition. To do so, the article addresses four central ideas: (i) the dialectic conception of space to problematize the production and appropriation of urban common spaces; (ii) the recognition of urban common spaces as spaces traversed by contradictions, disputes and material and symbolic conflicts among different agents; (iii) the right to the city as a need and as a utopian project; and (iv) the challenge of articulating heterotopic practices from the perspective of creative rebellion for the right to the city and the transition to a new urban future.

  17. String theory dualities from M-theory

    International Nuclear Information System (INIS)

    We analyze how string theory dualities may be described in M-theory. T-dualities arise from scalar-vector dualities in the worldvolume of the membrane of M-theory. ''electric-magnetic'' dualities arise from a duality transformation in M-theory compactified on a 3-torus, which takes the membrane into a fivebrane wrapped around the 3-torus. We show how the action of the membrane transforms into the action of the wrapped fivebrane by this transformation. Other ''electric-magnetic'' dualities are related to this duality by compactifications and orbifoldings. (orig.)

    We propose a correspondence between loop operators in a family of four dimensional mathcal{N} = 2 gauge theories on S 4 — including Wilson, ‘t Hooft and dyonic operators — and Liouville theory loop operators on a Riemann surface. This extends the beautiful relation between the partition function of these mathcal{N} = 2 gauge theories and Liouville correlators found by Alday, Gaiotto and Tachikawa. We show that the computation of these Liouville correlators with the insertion of a Liouville loop operator reproduces Pestun’s formula capturing the expectation value of a Wilson loop operator in the corresponding gauge theory. We prove that our definition of Liouville loop operators is invariant under modular transformations, which given our correspondence, implies the conjectured action of S-duality on the gauge theory loop operators. Our computations in Liouville theory make an explicit prediction for the exact expectation value of ’t Hooft and dyonic loop operators in these mathcal{N} = 2 gauge theories. The Liouville loop operators are also found to admit a simple geometric interpretation within quantum Teichmüller theory as the quantum operators representing the length of geodesics. We study the algebra of Liouville loop operators and show that it gives evidence for our proposal as well as providing definite predictions for the operator product expansion of loop operators in gauge theory.

We show that the computation of these Liouville correlators with the insertion of a Liouville loop operator reproduces Pestun's formula capturing the expectation value of a Wilson loop operator in the corresponding gauge theory. We prove that our definition of Liouville loop operators is invariant under modular transformations, which given our correspondence, implies the conjectured action of S-duality on the gauge theory loop operators. Our computations in Liouville theory make an explicit prediction for the exact expectation value of 't Hooft and dyonic loop operators in these N=2 gauge theories. The Liouville loop operators are also found to admit a simple geometric interpretation within quantum Teichmueller theory as the quantum operators representing the length of geodesics. We study the algebra of Liouville loop operators and show that it gives evidence for our proposal as well as providing definite predictions for the operator product expansion of loop operators in gauge theory.

  20. Obliczeniowe teorie ?wiadomo?ci (Computational theories of consciousness

    Directory of Open Access Journals (Sweden)

    Marcin Mi?kowski

    2010-06-01

    Full Text Available In this paper, I review the motivations for having a computational theory of consciousness to see if they turn out to be no longer plausible in the light of recent criticisms. These criticisms focus on the alleged inability of computational theories to deal with qualia, or qualities of experience (or objects of experience in some accounts, and with so-called symbol grounding on the other hand. Yet it seems that computationalism remains the best game in town when one wants to explain and predict the dynamics of information processing of cognitive systems. Conscious information processing does not seem to be explainable better within any other framework; computationalism regarding consciousness can only be discarded by supposing that consciousness is epiphenomenal in information processing.I will argue that recent theories of consciousness that are to deal with the so-called hard problem of consciousness remain in their core computational if they do not subscribe to epiphenomenalism. For example, the quantum theory as proposed by Stuart Hameroff remains openly computational; the same goes for pan(protopsychist speculation of David Chalmers. The qualitative character of information processing that Chalmers takes to explain the existence of subjective experience piggy-backs, so to say, on the very fact that there is information processing that is best explained in a computationalist framework. I also briefly show that other alternative accounts of consciousness (such as direct theories of consciousness that were supposed to oppose computational and functionalist conceptions are not only compatible with them but require them to begin with.In short, to discard credentials of computationalism in consciousness research one would have to show that it`s possible to explain conscious information-processing mechanisms sufficiently in a non-computational way. And this has not been done by any of the critics of computational accounts. This all doesn`t suggest, though, that computational explanation is sufficient for building a complete theory of consciousness; it might however be necessary.

  1. Neo-newtonian theories

    CERN Document Server

    Fabris, J C

    2015-01-01

    General Relativity is the modern theory of gravitation. It has replaced the newtonian theory in the description of the gravitational phenomena. In spite of the remarkable success of the General Relativity Theory, the newtonian gravitational theory is still largely employed, since General Relativity, in most of the cases, just makes very small corrections to the newtonian predictions. Moreover, the newtonian theory is much simpler, technically and conceptually, when compared to the relativistic theory. In this text, we discuss the possibility of extending the traditional newtonian theory in order to incorporate typical relativistic effects, but keeping the simplicity of the newtonian framework. We denominate these extensions neo-newtonian theories. These theories are discussed mainly in the contexts of cosmology and compact astrophysical objects.

  2. A Network Text Analysis of David Ayer’s Fury

    2015-12-01

    Full Text Available Network Text Analysis (NTA involves the creation of networks of words and/or concepts from linguistic data. Its key insight is that the position of words and concepts in a text network provides vital clues to the central and underlying themes of the text as a whole. Recent research has relied on inductive approaches to identify these themes. In this study we demonstrate a deductive approach that we apply to the screenplay of the 2014 World War II-era film Fury. Specifically, we first use genre expectations theory to establish prior expectations as to the key themes associated with war films. We then empirically test whether words and concepts associated with the most influentially-positioned nodes are consistent with themes common to the war-film genre. As predicted, we find that words and concepts associated with the least constrained nodes in the text network were significantly more likely to be associated with the war, action, and biography genres and significantly less likely to be associated with the mystery, science-fiction, fantasy, and film-noir genres.Keywords: content analysis, text analysis, network text analysis, semantic network analysis, film studies, screenplay, screenwriting, war movies, World War II, tanks

  7. OBITUARY: Eur.Ing. Professor David Dew-Hughes in memoriam

    Science.gov (United States)

    Campbell, Archie; Dew-Hughes, Denise; Donaldson, Gordon; Palmer, Richard

    2007-06-01

    We regret to announce the death of David Dew-Hughes, the second Honorary Editor of Superconductor Science and Technology, in Autumn 2006. He was born in Manchester, the eldest of three children, attended Manchester Grammar School and took his first degree in metallurgy at Birmingham, before undertaking a Doctorate of Engineering at Yale University. After initial work for IBM on semiconductors, he returned to England as a lecturer in metallurgy at Cambridge University. There he devoted his career to superconductivity long before it became fashionable, starting a group on the properties of what we now know as type II materials, with his students Jan Evetts, Archie Campbell and Anant Narlikar. Between them they paved the way to our understanding of the magnetic vortex properties of these materials, and thus to the development of modern practical materials for superconducting magnets. Eur.Ing. Professor David Dew-Hughes 1932-2006 In 1965 he became a founding Senior Lecturer in physics at Lancaster University, moving to Brookhaven National Laboratory in 1974. His final academic post was in engineering science at Oxford University where he also held a University College Tutorial Fellowship. As long ago as 1971 David wrote an authoritative review for Reports on Progress in Physics on 'The metallurgical enhancement of type II superconductors'. Following the discovery of high-Tc superconductivity, IOP Publishing launched Superconductor Science and Technology in 1988 and he was a founder member of its Editorial Board. When Jan Evetts retired as Honorary Editor in 1992, David was the natural choice as his successor. He served a five year term and remained on the Board as Deputy Editor until the end of 2000. To mark the 10th anniversary of high-temperature superconductivity in 1997, David edited a special issue of Superconductor Science and Technology in which past and present members of the Editorial Board contributed reviews of their specialities. He noted that at that time much progress had been made in the study of the chemistry, phase relationships, crystallography, basic physics and materials science of the mixed-oxide systems and the physics of vortices, their configurations, dynamics and interactions with lattice defects. Writing from the perspective of one whose primary interest was in the applications of HTS, he compared the then situation with regard to the development of commercial applications of HTS to the commercial development of low-temperature superconductors. The main commercial application for HTS was yet to be identified, but if the comparison with LTS was accepted, the outlook was hopeful. At the 20th anniversary of high-Tc, now is perhaps a good time for a similar review, but most of David's conclusions still look valid ten years on. The superconductivity community laments his untimely passing and will sorely miss him.

  16. The theories on inequality: class theory

    Directory of Open Access Journals (Sweden)

    Ali Arslan

    2006-11-01

    Full Text Available This stduy aims to analyse  class theory and its major expansions. In addition, the problems and dilemmas of class theory are discussed. Social inequality, either socially or economically, is one of the most common features of capitalist societies. Some people or some social groups have more money, more prestige, more privilege and more influence on the decision making process.               Two main strategies have been used for analysing and explaining inequalities. The first and most popular strategy is “class theory” which stresses ownership and control to explain class differentiation. It concentrates on the inequalities based mainly on the ownership or non-ownership of economic resources. Class theory was fathered by Karl Marx and especially developed by Marxist writers. Class analysts focus on identification of classes as the major social forces of society. There are two main schools of thought in class theory with their variations within each school: a Marxist Class Theory, b Weberian Class Theory  If the Marxist class analysis and Weberian class analysis are examined it will be seen that, two approaches are incompatible and it is impossible to synthesise them. Nevertheless, Hindess sees Weber’s view as the correction of and supplement to Marx’s ideas rather than an alternative. When the ideas of Marx and Weber are compared, it will be clearly seen that both Marx and Weber explain classes in relation to the economy. Nevertheless, while Marx defines classes in terms of the relations of production, Weber defines them in relation to the market.

  8. David Schoenberg and the beauty of quantum oscillations

    International Nuclear Information System (INIS)

    The quantum oscillation effect was discovered in Leiden, in 1930, by W.J. de Haas and P.M. van Alphen in magnetization measurement, and by L.W. Shubnikov and de Haas - in magnetoresistance. Studying single crystals of bismuth, they observed oscillatory variations of magnetization and magnetoresistance with magnetic field. Shoenberg, whose first research in Cambridge had been on bismuth, found that much stronger oscillations are observed when a bismuth sample is cooled to liquid helium rather than to liquid hydrogen, which had been used by de Haas. In 1938 Shoenberg came from Cambridge to Moscow to study these oscillations at Kapitza Institute where liquid helium was available at that time. In 1947, J. Marcus observed similar oscillations in zinc, that persuaded Shoenberg to return to this research, and, since then, the dHvA effect had been one of his main research topic. In particular, he developed techniques for quantitative measurements of the effect in many metals. Theoretical explanation of quantum oscillations was given by L. Onsager in 1952, and the analytical quantitative theory by I.M. Lifshitz and A.M. Kosevich in 1955. These theoretical advancements seemed to provide a comprehensive description of the effect. Since then, quantum oscillations were commonly considered as a tool for measuring Fermi surface extremal cross-sections and all-angle electron scattering times. However, in his pioneering experiments in 1960s, Shoenberg revealed the richness and deep essence of the quantum oscillation effect and showed how the beauty of the effect is disclosed under nonlinear conditions imposed by interactions in the system under study. It was quite unexpected, that under 'magnetic interaction' conditions, the apparently weak effect of quantum oscillations may lead to such strong consequences as breaking the sample into magnetic (now called 'Shoenberg') domains and the formation of an inhomogeneous magnetic state. Owing to his contribution to the field of quantum oscillations and superconductivity, Shoenberg is no doubt one of the 20th century's foremost experts. We describe the experiments on finding the quantitative parameters of electron-electron interaction, which are in line with the Shoenberg ideas that the quantum oscillations are modified by interactions and, hence, their analysis enables one to extract the quasiparticle interaction parameters.

  9. Supersymmetric gauge theories from string theory

    International Nuclear Information System (INIS)

    This thesis presents various ways to construct four-dimensional quantum field theories from string theory. In a first part we study the generation of a supersymmetric Yang-Mills theory, coupled to an adjoint chiral superfield, from type IIB string theory on non-compact Calabi-Yau manifolds, with D-branes wrapping certain sub-cycles. Properties of the gauge theory are then mapped to the geometric structure of the Calabi-Yau space. Even if the Calabi-Yau geometry is too complicated to evaluate the geometric integrals explicitly, one can then always use matrix model perturbation theory to calculate the effective superpotential. The second part of this work covers the generation of four-dimensional super-symmetric gauge theories, carrying several important characteristic features of the standard model, from compactifications of eleven-dimensional supergravity on G2-manifolds. If the latter contain conical singularities, chiral fermions are present in the four-dimensional gauge theory, which potentially lead to anomalies. We show that, locally at each singularity, these anomalies are cancelled by the non-invariance of the classical action through a mechanism called 'anomaly inflow'. Unfortunately, no explicit metric of a compact G2-manifold is known. Here we construct families of metrics on compact weak G2-manifolds, which contain two conical singularities. Weak G2-manifolds have properties that are similar to the ones of proper G2-manifolds, and hence the explicit examples might be useful to better understand the generic situation. Finally, we reconsider the relation between eleven-dimensional supergravity and the E8 x E8-heterotic string. This is done by carefully studying the anomalies that appear if the supergravity theory is formulated on a ten-manifold times the interval. Again we find that the anomalies cancel locally at the boundaries of the interval through anomaly inflow, provided one suitably modifies the classical action. (author)

    Few individuals have left a more indelible mark on the history of aviation medicine than the wartime Air Surgeon of the U.S. Army Air Forces, David N. W. Grant. In spite of having built an incomparable air evacuation service, created the Flight Nurse Corps, instituted psychological evaluations for aircrews, and a host of other achievements, little is known about Grant the man, or about how he came to be the Air Surgeon. This paper will describe Grant's early life and military career, and will focus on his gradual accumulation of the knowledge and personal qualities that made him an outstanding, if virtually unsung, leader of World War II.

    Grunwald, Peter D

    2008-01-01

    We introduce algorithmic information theory, also known as the theory of Kolmogorov complexity. We explain the main concepts of this quantitative approach to defining `information'. We discuss the extent to which Kolmogorov's and Shannon's information theory have a common purpose, and where they are fundamentally different. We indicate how recent developments within the theory allow one to formally distinguish between `structural' (meaningful) and `random' information as measured by the Kolmogorov structure function, which leads to a mathematical formalization of Occam's razor in inductive inference. We end by discussing some of the philosophical implications of the theory.

  14. String theory symmetries

    CERN Document Server

    Schwarz, J H

    1995-01-01

    A brief review of the status of duality symmetries in string theory is presented. The evidence is accumulating rapidly that an enormous group of duality symmetries, including perturbative T dualities and non-perturbative S-dualities, underlies string theory. It is my hope that an understanding of these symmetries will suggest the right way to formulate non-perturbative string theory. Whether or not this hope is realized, it has already been demonstrated that this line of inquiry leads to powerful new tools for understanding gauge theories and new evidence for the uniqueness of string theory, as well as deep mathematical results.

    Full Text Available Over the past decade, f(R theories have been extensively studied as one of the simplest modifications to General Relativity. In this article we review various applications of f(R theories to cosmology and gravity – such as inflation, dark energy, local gravity constraints, cosmological perturbations, and spherically symmetric solutions in weak and strong gravitational backgrounds. We present a number of ways to distinguish those theories from General Relativity observationally and experimentally. We also discuss the extension to other modified gravity theories such as Brans–Dicke theory and Gauss–Bonnet gravity, and address models that can satisfy both cosmological and local gravity constraints.

    1988-01-01

    In recent years the interplay between model theory and other branches of mathematics has led to many deep and intriguing results. In this, the first book on the topic, the theme is the interplay between model theory and the theory of modules. The book is intended to be a self-contained introduction to the subject and introduces the requisite model theory and module theory as it is needed. Dr Prest develops the basic ideas concerning what can be said about modules using the information which may be expressed in a first-order language. Later chapters discuss stability-theoretic aspects of module

    Special Theory of Relativity provides a discussion of the special theory of relativity. Special relativity is not, like other scientific theories, a statement about the matter that forms the physical world, but has the form of a condition that the explicit physical theories must satisfy. It is thus a form of description, playing to some extent the role of the grammar of physics, prescribing which combinations of theoretical statements are admissible as descriptions of the physical world. Thus, to describe it, one needs also to describe those specific theories and to say how much they are limit

    Parameterized complexity theory is a recent branch of computational complexity theory that provides a framework for a refined analysis of hard algorithmic problems. The central notion of the theory, fixed-parameter tractability, has led to the development of various new algorithmic techniques and a whole new theory of intractability. This book is a state-of-the-art introduction into both algorithmic techniques for fixed-parameter tractability and the structural theory of parameterized complexity classes, and it presents detailed proofs of recent advanced results that have not appeared in book

    Junior, Ednaldo L B

    2015-01-01

    We construct a theory in which the gravitational interaction is described only by torsion, but that generalizes the Teleparallel Theory still keeping the invariance of local Lorentz transformations. We show that our theory falls, to a certain limit of a real parameter, in the $f(R)$ Gravity or, to another limit of the same real parameter, in a modified $f(T)$ Gravity, interpolating between these two theories and still can fall on several other theories. We explicitly show the equivalence with $f(R)$ Gravity for cases of Friedmann-Lemaitre-Robertson-Walker flat metric for diagonal tetrads, and a metric with spherical symmetry for diagonal and non-diagonal tetrads.

  4. Quantum algorithmic information theory

    Svozil, K

    1995-01-01

    The agenda of quantum algorithmic information theory, ordered `top-down,' is the quantum halting amplitude, followed by the quantum algorithmic information content, which in turn requires the theory of quantum computation. The fundamental atoms processed by quantum computation are the quantum bits which are dealt with in quantum information theory. The theory of quantum computation will be based upon a model of universal quantum computer whose elementary unit is a two-port interferometer capable of arbitrary U(2) transformations. Basic to all these considerations is quantum theory, in particular Hilbert space quantum mechanics.

    An approach to systematically implement open-closed string duality for free large $N$ gauge theories is summarised. We show how the relevant closed string moduli space emerges from a reorganisation of the Feynman diagrams contributing to free field correlators. We also indicate why the resulting integrand on moduli space has the right features to be that of a string theory on $AdS$.

    2011-01-01

    This book continues the fundamental work of Arnold Sommerfeld and David Hestenes formulating theoretical physics in terms of Minkowski space-time geometry. We see how the standard matrix version of the Dirac equation can be reformulated in terms of a real space-time algebra, thus revealing a geometric meaning for the “number i” in quantum mechanics. Next, it is examined in some detail how electroweak theory can be integrated into the Dirac theory and this way interpreted in terms of space-time geometry. Finally, some implications for quantum electrodynamics are considered.The presentation of real quantum electromagnetism is expressed in an addendum. The book covers both the use of the complex and the real languages and allows the reader acquainted with the first language to make a step by step translation to the second one.

  12. Abstraction Super-structuring Normal Forms: Towards a Theory of Structural Induction

    CERN Document Server

    Silvescu, Adrian

    2011-01-01

    Induction is the process by which we obtain predictive laws or theories or models of the world. We consider the structural aspect of induction. We answer the question as to whether we can find a finite and minmalistic set of operations on structural elements in terms of which any theory can be expressed. We identify abstraction (grouping similar entities) and super-structuring (combining topologically e.g., spatio-temporally close entities) as the essential structural operations in the induction process. We show that only two more structural operations, namely, reverse abstraction and reverse super-structuring (the duals of abstraction and super-structuring respectively) suffice in order to exploit the full power of Turing-equivalent generative grammars in induction. We explore the implications of this theorem with respect to the nature of hidden variables, radical positivism and the 2-century old claim of David Hume about the principles of connexion among ideas.

    DEFF Research Database (Denmark)

    Pries-Heje, Jan; Baskerville, Richard

    2014-01-01

    Technological knowledge has been characterized as having a scope that is specific to a particular problem. However, the information systems community is exploring forms of design science research that provide a promising avenue to technological knowledge with broader scope: design theories. Because design science research is materially prescriptive, it requires a different perspective in developing the breadth of applications of design theories. In this paper we propose different concepts that embody forms of general technological knowledge The concept of projectability, developed originally as a means of distinguishing realized generalizations from unrealized generalizations, helps explain how design theories, being prescriptive, possess a different form of applicability. The concept of entrenchment describes the use of a theory in many projections. Together these concepts provide a means for comparative discussions of the importance of design theories. Projectable design theories guide designers in the design of artifacts similar in principle, but different in context. These can also help design researchers understand interrelationships between design theories.

  15. Geophysical Field Theory

    International Nuclear Information System (INIS)

    The geophysical field theory includes the basic principles of electromagnetism, continuum mechanics, and potential theory upon which the computational modelling of geophysical phenomena is based on. Vector analysis is the main mathematical tool in the field analyses. Electrostatics, stationary electric current, magnetostatics, and electrodynamics form a central part of electromagnetism in geophysical field theory. Potential theory concerns especially gravity, but also electrostatics and magnetostatics. Solid state mechanics and fluid mechanics are central parts in continuum mechanics. Also the theories of elastic waves and rock mechanics belong to geophysical solid state mechanics. The theories of geohydrology and mass transport form one central field theory in geophysical fluid mechanics. Also heat transfer is included in continuum mechanics. (orig.)

    CERN Document Server

    Niederreiter, Harald

    2015-01-01

    This textbook effectively builds a bridge from basic number theory to recent advances in applied number theory. It presents the first unified account of the four major areas of application where number theory plays a fundamental role, namely cryptography, coding theory, quasi-Monte Carlo methods, and pseudorandom number generation, allowing the authors to delineate the manifold links and interrelations between these areas.  Number theory, which Carl-Friedrich Gauss famously dubbed the queen of mathematics, has always been considered a very beautiful field of mathematics, producing lovely results and elegant proofs. While only very few real-life applications were known in the past, today number theory can be found in everyday life: in supermarket bar code scanners, in our cars’ GPS systems, in online banking, etc.  Starting with a brief introductory course on number theory in Chapter 1, which makes the book more accessible for undergraduates, the authors describe the four main application areas in Chapters...

  17. String Theory Without Branes

    CERN Document Server

    Johnson, C V

    2006-01-01

    We present a class of solvable models that resemble string theories in many respects but have a strikingly different non-perturbative sector. In particular, there are no exponentially small contributions to perturbation theory in the string coupling, which normally are associated with branes and related objects. Perturbation theory is no longer an asymptotic expansion, and so can be completely re-summed to yield all the non-perturbative physics. We examine a number of other properties of the theories, for example constructing and examining the physics of loop operators, which can be computed exactly, and gain considerable understanding of the difference between these new theories and the more familiar ones, including the possibility of how to interpolate between the two types. Interestingly, the models we exhibit contain a family of zeros of the partition function which suggest a novel phase structure. The theories are defined naturally by starting with models that yield well-understood string theories and al...

  18. Matrix theory of gravitation

    Science.gov (United States)

    Köhler, Wolfgang

    2011-06-01

    A new classical theory of gravitation within the framework of general relativity is presented. It is based on a matrix formulation of four-dimensional Riemann-spaces and uses no artificial fields or adjustable parameters. The geometrical stress-energy tensor is derived from a matrix-trace Lagrangian, which is not equivalent to the curvature scalar R. To enable a direct comparison with the Einstein-theory a tetrad formalism is utilized, which shows similarities to teleparallel gravitation theories, but uses complex tetrads. Matrix theory might solve a 27-year-old, fundamental problem of those theories (Sect. 4.1). For the standard test cases (PPN scheme, Schwarz schild-solution) no differences to the Einstein-theory are found. However, the matrix theory exhibits novel, interesting vacuum solutions.

  19. Operational quantum theory

    Saller, Heinrich

    2006-01-01

    Operational Quantum Theory I is a distinguished work on quantum theory at an advanced algebraic level. The classically oriented hierarchy with objects such as particles as the primary focus, and interactions of these objects as the secondary focus is reversed with the operational interactions as basic quantum structures. Quantum theory, specifically nonrelativistic quantum mechanics, is developed from the theory of Lie group and Lie algebra operations acting on both finite and infinite dimensional vector spaces. In this book, time and space related finite dimensional representation structures and simple Lie operations, and as a non-relativistic application, the Kepler problem which has long fascinated quantum theorists, are dealt with in some detail. Operational Quantum Theory I features many structures which allow the reader to better understand the applications of operational quantum theory, and to provide conceptually appropriate descriptions of the subject. Operational Quantum Theory I aims to understand ...

    Full Text Available Many centuries before Joseph Conrad’s Heart of Darkness (1902 and Rudyard Kipling’s Kim (1901 were published, the East and West were still divided, as in Tacito’s De Germania, by a limes also visible in David Malouf’s An Imaginary Life (1978, in which the poet Ovid exiled at Tomi, is friends with the savage Child, of animal nature in a human body, similar to the metamorphic migrants of Salman Rushdie’s The Satanic Verses (1988, which hides the magnificent and ancient East of Mah?bh?rata and R?m?yana in many Western identities, lost in diabolic European cities. This chaotic antithesis in Michael Ondaatje’s pages lets Sri Lanka’s childish ghosts float amidst stories of peregrination and in search of a Promised Land. In the Skin of a Lion (1987 includes an epigraph from the ancient poem of Gilgamesh, an Eastern echo in a novel profoundly important for many Western studies that often focus on the theory of the canon or on postmodern literature. These categories are discussed with the prospect of broadening cultural and post-colonial studies, in order to merge theory of genres and thematic criticism with anthropology, mythology, and ethnology. Multiple citations expand the original object of research, adding the colonial prophecy present in North American myths, as demonstrated by Margaret Atwood, Margaret Laurence or Lévi-Strauss. Incessantly moving from one space to another, authors give voice to the native cry from multiple perspectives, narrating – like all colonial empires founded on human cruelty– the beast’s nature that has shown its worst aspect.

    Full Text Available El artículo aborda los alcances de la propuesta moral de David Hume, específicamente la idea de que, ante la imposibilidad de realizar propósitos morales sinceros, el camino que queda para el individuo es fingir que dichos sentimientos se han adquirido. Tal actitud es vista por el autor como favorab [...] le para las buenas relaciones sociales y para la construcción de acuerdos de convivencia entre individuos egoístas posesivos. Sin embargo, dado el radical determinismo de la mente concebido por Hume, tal esfuerzo mostraría la intención por coadyuvar a soluciones pacíficas al problema de la insociabilidad, pero no tendría efectos reales sobre las pasiones originales de los individuos. Abstract in english This essay brings up the extent of David Hume's moral proposal; specifically, the idea that facing the impossibility of accomplish sincere moral aims the individual is left to feign that such sentiments have been acquired.

Nevertheless, given such radical determinism of the mind conceived by Hume, the effort would remark only the attempts to team up with for reaching peaceful solutions for the problems of unsociability but would not have real effects over the original passions of the individuals.

    What does it mean to be a mentor in science? Definitions of mentorship are freely spouted in publications and include concepts such as academic support, professional development, role modeling, interaction, impartment of knowledge, evaluation of work, demonstration of methodology, etc. Perhaps most of us would agree with the duties listed. But just what does it mean, for example, to offer academic support? How might one facilitate professional development for a mentee? While we may agree to the general obligations of a mentor the specifics of what these entail would prove more controversial. This article will illustrate how easy it is to pick out a bad mentor. There are certain elements of conduct that, if practiced, undoubtedly put you in the "bad mentor" category. However, it is very difficult to explain just what it means to be not only an adequate mentor but also a stellar one. It may be easy to list the roles and responsibilities of a mentor but just how should they be performed/carried out? David Triggle is the model of an extraordinary mentor. The conclusion of this paper will focus on some specific mentorship activities David Triggle carried out that illustrate some of the intangible aspects of excellence in mentorship. PMID:26206190

    Full Text Available This essay analyzes two works, My Brother by Jamaica Kincaid, and "Saturn Street" by David Leavitt, investigating the construction of homosexuality as a process accomplished by resorting to illness (AIDS and death. In both works, indeed, the slow and dramatic course of AIDS amounts to the progressive unveiling of homosexuality as a social threat or a cause of anxiety and repulsion. The two works are set in different contexts: whereas Jamaica Kincaid refers to the problematic situation of homosexuality in the Caribbean, David Leavitt explores the social and cultural scenario of the 1990s Los Angeles, in the wake of a by now ended utopian confidence in science and technology.  This comparative approach helps us understand the political dynamics through which, in different and, to some extents, opposite realities, the social stigma of AIDS worked as a means to construct homosexual identity and set it apart from the sanitized spectrum of normal and sanctioned sexual behaviors. The point I want to make in this essay is that the corpse is used as an effective metaphor for a dehumanized depiction of male homosexual and ill subjects.  

  5. The Global Approach to Quantum Field Theory

    International Nuclear Information System (INIS)

    Parts I and II develop the basic classical and quantum kinematics of fields and other dynamical systems. The presentation is conducted in the utmost generality, allowing for dynamical quantities that may be anticommuting (supernumbers) and theories subject to the most general possible gauge symmetry. The basic ingredients are action functionals and the Peierls bracket, a manifestly covariant replacement for the Poisson bracket and equal-time commutation relations. For DeWitt the logical progression is Peierls bracket ? Schwinger action principle ? Feynman functional integral although he points out that the historical development was in the opposite order. It must be pointed out that the Peierls-Schwinger-DeWitt approach, despite some advantages over initial-value formulations, has some troubles of its own. In particular, it has never completely escaped from the arena of scattering theory, the paradigm of conventional particle physics. One is naturally led to study matrix elements between an 'in-vacuum' and an 'out-vacuum' though such concepts are murky in situations, such as big bangs and black holes, where the ambient geometry is not asymptotically static in the far past and future. The newest material in the treatise appears in two chapters in part II devoted to the interpretation of quantum theory, incorporating some unpublished work of David Deutsch on the meaning of probability in physics. Parts III through V apply the formalism in depth to successively more difficult classes of systems: quantum mechanics, linear (free) fields, and interacting fields. DeWitt's characteristic tools of effective actions, heat kernels, and ghost fields are developed. Chapters 26 and 31 outline new approaches developed in collaboration with DeWitt's recent students C Molina-Paris and C Y Wang, respectively. The most of parts VI and VII consist of special topics, such as anomalies, particle creation by external fields, Unruh acceleration temperature, black holes, and Euclideanization. Chapter 30, on black holes and Hawking radiation, will be very familiar to readers of DeWitt's influential review article. Chapter 28, on anomalies, makes a careful distinction (missing from many treatments) between 'critical' anomalies, which render equations of motion inconsistent in the (would-be) quantum theory, and harmless anomalies that merely invalidate predictions that would classically follow from certain symmetries. Examples of critical anomalies are the chiral anomaly of a spinor field coupled to a non-Abelian gauge field and the anomaly in the conservation law of the stress tensor of certain pathological theories. DeWitt's chapter calculates the trace and chiral anomalies in detail. The last two chapters of part VII treat the most important particular quantum field theories. Chapter 34 develops many of the textbook predictions of quantum eletrodynamics from DeWitt's starting point. Chapter 35 covers Yang-Mills fields and quantum gravity. The discussion of gravity is surprisingly brief, in view of DeWitt's lifelong preoccupation with that subject. He rejects renormalizable fourth-order modifications of four-dimensional gravity because he could not stomach unfriendly ghosts (states of negative norm or unboundedly negative energy) nor the technical difficulties of integrating such theories into the functional-integral formalism. Finally, there is part VIII, entitled 'Examples. Simple Exercises in the Use of the Global Formalism'. It consists of 25 short chapters numbered separately from those of the main text. The preface recommends reading these and the main text in parallel. Most valuable in my opinion is a string of successively more complicated fermionic models. Hidden in an appendix is a crucial motivational paragraph: Super Hilbert spaces are generalizations of ordinary Hilbert spaces, designed so as to enable one to consider quantum systems with supernumber-valued parameters (e.g., a-type external sources) which, themselves, are introduced in order to present, in a compact algebraic way, certain relationships between real physical ampli

  7. Nordenfelt's theory of disability.

    Science.gov (United States)

    Edwards, S D

    1998-01-01

    This paper is an attempt to provide a critical evaluation of the theory of disability put forward by Lennart Nordenfelt. The paper is in five sections. The first sets out the main elements of Nordenfelt's theory. The second section elaborates the theory further, identifies a tension in the theory, and three kinds of problems for it. The tension derives from Nordenfelt's attempt to respect two important but conflicting constraints on a theory of health. The problems derive from characterisation of the goals of persons; the difficulty which Nordenfelt has in respecting the plausible view that there is a distinction between illness and disability; and the presence in the theory of other strongly counterintuitive implications. In section three a defence of Nordenfelt is attempted from within the resources available within his own theory. This defence seeks to exploit his distinctions between a person who is ill and one who is 'generally disabled' and that between first- and second-order disabilities. However, it is concluded that there are insufficient resources within Nordenfelt's theory to fend off the criticisms developed in section two. The fourth section of the paper attempts a defence of Nordenfelt. It is claimed that introduction of the concept of capacity helps to explain differences between problem cases in the theory. Finally, it is shown that at least two important constraints on any theory of disability emerge from the preceding discussion. PMID:9564089

    Full Text Available Christine M. Klapeer legt in diesem Einführungsband dar, aus welchen politischen und theoretischen Kontexten heraus sich ‚queer‘ zu einem Begriff mit besonderem politischem und theoretischem Gehalt entwickelt hat. Wesentlich zielt sie dabei auf eine kritische Kontextualisierung von „queer theory”. Die Autorin geht zunächst auf das Gay Liberation Movement ein, grenzt die Queer Theory vom Poststrukturalismus, von feministischen Theorien und den Lesbian and Gay Studies ab, beleuchtet Eckpunkte queeren Denkens und zeichnet schließlich die Entwicklungen in Österreich sowohl politisch-rechtlich als auch bewegungsgeschichtlich und in der Wissenschaftslandschaft nach.Christine M. Klapeer’s introductory volume demonstrates the manner in which ‘queer’ grew out of various political and theoretical contexts to become a term with special political and theoretical content. She focuses primarily on a critical contextualization of “queer theory.” The author begins by approaching the Gay Liberation Movement and then distinguishes Queer Theory from poststructuralism, from feminist theories, and from Lesbian and Gay Studies. She continues on to illuminate the key aspects of queer thought and concludes by sketching the development in Austria in terms of politics and the law, the history of movements, and within the landscape of knowledge.

  12. Group field theories

    2012-01-01

    Group field theories are particular quantum field theories defined on D copies of a group which reproduce spin foam amplitudes on a space-time of dimension D. In these lecture notes, we present the general construction of group field theories, merging ideas from tensor models and loop quantum gravity. This lecture is organized as follows. In the first section, we present basic aspects of quantum field theory and matrix models. The second section is devoted to general aspects of tensor models and group field theory and in the last section we examine properties of the group field formulation of BF theory and the EPRL model. We conclude with a few possible research topics, like the construction of a continuum limit based on the double scaling limit or the relation to loop quantum gravity through Schwinger-Dyson equations

  13. Generalized Higher Gauge Theory

    CERN Document Server

    Ritter, Patricia; Schmidt, Lennart

    2015-01-01

    We study a generalization of higher gauge theory which makes use of generalized geometry and seems to be closely related to double field theory. The local kinematical data of this theory is captured by morphisms of graded manifolds between the canonical exact Courant Lie 2-algebroid $TM\\oplus T^*M$ over some manifold $M$ and a semistrict gauge Lie 2-algebra. We discuss generalized curvatures and their infinitesimal gauge transformations. Finite gauge transformation as well as global kinematical data are then obtained from principal 2-bundles over 2-spaces. As dynamical principle, we consider first the canonical Chern-Simons action for such a gauge theory. We then show that a previously proposed 3-Lie algebra model for the six-dimensional (2,0) theory is very naturally interpreted as a generalized higher gauge theory.

  14. Is string theory true?

    International Nuclear Information System (INIS)

    String theory allows physicists to unify the 4 basic interactions, gravity included. This theory assumes that each elementary particle is represented by a string that vibrates in a 9-dimension space. One success of this theory concerns black holes. In 1997 a group of physicists developed a model based on string theory that yielded a theoretical result that had been discovered 20 years earlier: any black hole is a low intensity source of radiation due to quantum processes. String theory lacks experimental confirmations but some predictions could be tested in the LHC (large hadron collider) that is planned to be put in service in 2005. String theory implies supersymmetry, it means that each particle has a counterpart particle called sparticle that is much heavier, these sparticles might be detected in the next generation of particle accelerators.

    We prove that every perfect torsion theory for a ring $R$ is differential (in the sense of [P. E. Bland, Differential torsion theory, Journal of Pure and Applied Algebra 204 (2006) 1 -- 8]). In this case, we construct the extension of a derivation of a right $R$-module $M$ to a derivation of the module of quotients of $M$. Then, we prove that the Lambek and Goldie torsion theories for any $R$ are differential.

    The theory of games (or game theory) is a mathematical theory that deals with the general features of competitive situations. It involves strategic thinking, and studies the way people interact while making economic policies, contesting elections and other such decisions.

    After having explained Samuel Clarke's conception of the new philosophy of physical reality, we will treat the electron field in this context as a field modifying the void. From this we will be able to derive the so-called quantum rules just from Noether's theorem on conserved currents. Thus quantum theory appears as a kind of nonlocal field theory, in fact a new theory.

We draw on ideas from optimum control and game theory to provide a ‘game theory of mind’.

Critically, the joint value functions and ensuing behaviour are optimised recursively, under the assumption that I represent your value func...

    The thesis of theory-ladenness of observations, in its various guises, is widely considered as either ill-conceived or harmless to the rationality of science. The latter view rests partly on the work of the proponents of New Experimentalism who have argued, among other things, that experimental practices are efficient in guarding against any epistemological threat posed by theory-ladenness. In this paper I show that one can generate a thesis of theory-ladenness for experimental practices from an...

    The older time dependent scattering theory was concerned with scattering waves and amplitudes, and was based on the Sommerfeld radiation condition and, when incorporated into the Schrodinger equation as a Cauchy condition at infinity, leads to the Lippmann-Schwinger equation. In the newer stationary scattering theory, solving the Lippmann-Schwinger equation leads to a linear map between generalized eigenfunctions of perturbed and unperturbed operators. This map is the section at fixed energy of the wave operator from the older time dependent theory. The radiation condition can be shown to hold, a posteriori, in many situations, thus the link with prior physical theories

    I suspect that the growing 'body' of design theory may be infected by more inconsistency than is justifiable by genuine disagreement among design researchers. Taking my clue from Peirce, who argued that theory inevitably rests on basics metaphysical assumptions that theorists ought to be critically aware of, I demonstrate how 'insidious inconsistency ' may infect design theory if we ignore this admonition. As a possible remedy, I propose a method by which the philosophy of design may develop sound methaphysical foundations ('worldviews') for design theory - and obtain philosophical insights into design as a valuable side effect.

    The wavelength theory of light and color had been firmly established by the time the great German poet published his Theory of Colours in 1810. Nevertheless, Goethe believed that the theory derived from a fundamental error, in which an incidental result was mistaken for a elemental principle. Far from affecting a knowledge of physics, he maintained that such a background would inhibit understanding. The conclusions Goethe draws here rest entirely upon his personal observations.This volume does not have to be studied to be appreciated. The author's subjective theory of colors permits him to spe

    CERN Document Server

    Crisan, Mircea

    1989-01-01

    This book discusses the most important aspects of the theory. The phenomenological model is followed by the microscopic theory of superconductivity, in which modern formalism of the many-body theory is used to treat most important problems such as superconducting alloys, coexistence of superconductivity with the magnetic order, and superconductivity in quasi-one-dimensional systems. It concludes with a discussion on models for exotic and high temperature superconductivity. Its main aim is to review, as complete as possible, the theory of superconductivity from classical models and methods up t

  10. Theory in Social Marketing

    DEFF Research Database (Denmark)

    Hastings, Gerard; Brown, Abraham

    2010-01-01

    The chapter looks at three important theories which help social marketers to think more systematically about the key questions they need to address:  (i) how does the target group or population feel about a particular behaviour (Stages of Change Theory); (ii) what social and contextual factors influence this positioning (Social Cognitive Theory and Social Norms) and; (iii) what offerings might encourage them to change their behaviour – or, those in a position to do so, to make the social context more conducive to change (Exchange Theory). Moreover, the chapter outlines how social marketers might benefit from a social epistemological approach.

  11. Empirical comparison of theories

    International Nuclear Information System (INIS)

    The book represents the first, comprehensive attempt to take an empirical approach for comparative assessment of theories in sociology. The aims, problems, and advantages of the empirical approach are discussed in detail, and the three theories selected for the purpose of this work are explained. Their comparative assessment is performed within the framework of several research projects, which among other subjects also investigate the social aspects of the protest against nuclear power plants. The theories analysed in this context are the theory of mental incongruities and that of the benefit, and their efficiency in explaining protest behaviour is compared. (orig./HSCH)

    This is an introductory undergraduate textbook in set theory. In mathematics these days, essentially everything is a set. Some knowledge of set theory is necessary part of the background everyone needs for further study of mathematics. It is also possible to study set theory for its own interest--it is a subject with intruiging results anout simple objects. This book starts with material that nobody can do without. There is no end to what can be learned of set theory, but here is a beginning.

  13. Nonlocal gauge theories

    International Nuclear Information System (INIS)

    Nonlocal gauge theories, including gravitation, are considered. It is shown that to give a meaning to ?5-anomalous theories it is sufficient to introduce an additional nonlocal interaction. The introduction of such an interaction leads to a unitary macrocausal theory describing the interaction of massive vector fields with fermion fields. It is shown that nonlocal gauge theories with nonlocality scale ?/sub nl/ ? (1-10) TeV are capable of solving the hierarchy problem. An example of a nonlinear gauge model of grand unification is found in which topologically nontrivial monopole solutions with finite energy are absent

    2014-01-01

    Surgery theory, the basis for the classification theory of manifolds, is now about forty years old. There have been some extraordinary accomplishments in that time, which have led to enormously varied interactions with algebra, analysis, and geometry. Workers in many of these areas have often lamented the lack of a single source that surveys surgery theory and its applications. Indeed, no one person could write such a survey. The sixtieth birthday of C. T. C. Wall, one of the leaders of the founding generation of surgery theory, provided an opportunity to rectify the situation and produce a

  16. Generalized etale cohomology theories

    CERN Document Server

    Jardine, John F

    1997-01-01

    A generalized etale cohomology theory is a theory which is represented by a presheaf of spectra on an etale site for an algebraic variety, in analogy with the way an ordinary spectrum represents a cohomology theory for spaces. Examples include etale cohomology and etale K-theory. This book gives new and complete proofs of both Thomason's descent theorem for Bott periodic K-theory and the Nisnevich descent theorem. In doing so, it exposes most of the major ideas of the homotopy theory of presheaves of spectra, and generalized etale homology theories in particular. The treatment includes, for the purpose of adequately dealing with cup product structures, a development of stable homotopy theory for n-fold spectra, which is then promoted to the level of presheaves of n-fold spectra.   This book should be of interest to all researchers working in fields related to algebraic K-theory. The techniques presented here are essentially combinatorial, and hence algebraic. An extensive background in traditional stable hom...

  17. Introduction to string theory

    International Nuclear Information System (INIS)

    Open and closed boson theories are discussed in a classical framework, highlighting the physical interpretation of conformal symmetry and the Virasoro (1970) algebra. The quantification of bosonic strings is done within the old covariant operational formalism. This method is much less elegant and powerful than the BRST quantification, but it quickly reveals the physical content of quantum theory. Generalization to theories with fermionic degrees of freedom is introduced: the Neveu-Schartz (1971) and Ramond (1971) models, their reduced supersymmetry (two dimensions) and the Gliozzi, Scherk and Olive (1977) projection which leads to a supersymmetry theory in the usual meaning of the term

    In this informal review for non-specalists we discuss the construction of maximally supersymmetric gauge theories that arise on the worldvolumes branes in String Theory and M-Theory. Particular focus is made on the relatively recent construction of M2-brane worldvolume theories. In a formal sense, the existence of these quantum field theories can be viewed as predictions of M-Theory. Their construction is therefore a reinforcement of the ideas underlying String Theory and M-...

    Full Text Available At the beginning of the 1940s, Hebrew writer David Vogel (1891-1944 started to write a Yiddish novel for the first time. As an Austrian citizen living in France, he had been held in a camp for suspicious foreigners. His narrative, inspired by this experience, remained untitled after he was captured and sent to death by the Gestapo at the beginning of 1944. Its original version has never been published.This article gives an overview of critical approaches to this text that have been published up to now. It proposes an analysis based on Merleau-Ponty’s linguistic thought and on the principles of literary genetics. The manuscript, with its deletions and additions, is approached in the light of all the languages in which the author could have written in and that leave their mark on the narrative. The author of this article argues that the poetics of foreign language is more central than the question of Vogel’s linguistic identity. His writing in Yiddish thus poses the problem of the status of this language in a world where things are no longer called what they were.??????? 40?? ????? ???? ??? ?????????? ??????? ??? ???????

  1. De David Belasco à Giacomo Puccini : La Fanciulla del West, premier opéra « américain » From David Belasco to Giacomo Puccini:La Fanciulla del West, first “American” opera

    Directory of Open Access Journals (Sweden)

    Walter Zidaric

    2009-10-01

    Full Text Available La Fanciulla del West is a “horse opera” resulting from the second collaboration between David Belasco and Giacomo Puccini. This work, specially composed for the American stage, which had its world premiere at New York’s Metropolitan Opera in December 1910, paved the way for American composers who increasingly focused on American History in their quest for a “national” opera. For the first time, Puccini resorted to genuine Indian music, a Zuni melody, which he re-elaborated for dramatic purposes and associated with the nostalgic mood of uprooted people, the miners who left their home country for America. The Other – the native American viewed from the vantage point of the white, as well as the foreigner – no longer represented a threat, as had been the case in the operatic repertoire before, but became part and parcel of a multicultural society, like the Italian immigrant to whom Puccini also paid tribute. The Zuni melody, which opens and closes the opera, contributes to giving a genuine twist to a score which is the first one to tackle the foundations of the American nation.

  2. From Helmholtz to Schlick: The evolution of the sign-theory of perception.

    Science.gov (United States)

    Oberdan, Thomas

    2015-08-01

    Efforts to trace the influence of fin de siècle neo-Kantianism on early 20th Century philosophy of science have led scholars to recognize the powerful influence on Moritz Schlick of Hermann von Helmholtz, the doyen of 19th Century physics and a leader of the zur?ck zu Kant movement. But Michael Friedman thinks that Schlick misunderstood Helmholtz' signature philosophical doctrine, the sign-theory of perception. Indeed, Friedman has argued that Schlick transformed Helmholtz' Kantian view of spatial intuition into an empiricist version of the causal theory of perception. However, it will be argued that, despite the key role the sign-theory played in his epistemology, Schlick thought the Kantianism in Helmholtz' thought was deeply flawed, rendered obsolete by philosophical insights which emerged from recent scientific developments. So even though Schlick embraced the sign-theory, he rejected Helmholtz' ideas about spatial intuition. In fact, like his teacher, Max Planck, Schlick generalized the sign-theory into a form of structural realism. At the same time, Schlick borrowed the method of concept-formation developed by the formalist mathematicians, Moritz Pasch and David Hilbert, and combined it with the conventionalism of Henri Poincaré. Then, to link formally defined concepts with experience, Schlick's introduced his 'method of coincidences', similar to the 'point-coincidences' featured in Einstein's physics. The result was an original scientific philosophy, which owed much to contemporary scientific thinkers, but little to Kant or Kantianism. PMID:26193786

  3. Rotor theories by Professor Joukowsky: Momentum theories

    DEFF Research Database (Denmark)

    van Kuik, G. A. M.; SØrensen, Jens NØrkær

    2015-01-01

    This paper is the first of two papers on the history of rotor aerodynamics with special emphasis on the role of Joukowsky. The present one focuses on the development of the momentum theory while the second one surveys the development of vortex theory for rotors. Joukowsky has played a major role in these developments. Although he cooperated with other famous aerodynamicists like Prandtl, his contribution is not well recognized as most of his publications are in Russian. The paper discusses the role of the English, Russian and German research schools in the beginning of the Twentieth Century, and the contributions by individual researchers like Lanchester, Prandtl, Betz and Joukowslcy himself. After the one-dimensional momentum theory was well established, the introduction of torque and angular momentum was the next step. Joukowslcy has led the basis for this step, but Glauert's Blade Element Momentum still is the basis of current rotor design codes. He applied some assumptions limiting the validity to moderate and high tip speed ratios. Sorensen and van Kuik published a solution for wind turbines with very low tip speed ratios, which is now expanded to propellers as well, with one remaining assumption of inviscid flow. For very low tip speed ratios the general momentum theory gives unphysical results which disappear after applying a perturbation parameter representing phenomena not captured by the Euler equations.

  4. Dempster-Shafer theory and connections to information theory

    Science.gov (United States)

    Peri, Joseph S. J.

    2013-05-01

    The Dempster-Shafer theory is founded on probability theory. The entire machinery of probability theory, and that of measure theory, is at one's disposal for the understanding and the extension of the Dempster-Shafer theory. It is well known that information theory is also founded on probability theory. Claude Shannon developed, in the 1940's, the basic concepts of the theory and demonstrated their utility in communications and coding. Shannonian information theory is not, however, the only type of information theory. In the 1960's and 1970's, further developments in this field were made by French and Italian mathematicians. They developed information theory axiomatically, and discovered not only the Wiener- Shannon composition law, but also the hyperbolic law and the Inf-law. The objective of this paper is to demonstrate the mathematical connections between the Dempster Shafer theory and the various types of information theory. A simple engineering example will be used to demonstrate the utility of the concepts.

  9. Generic probabilistic theories : reconstruction of quantum theory

    International Nuclear Information System (INIS)

    This thesis is a collection of projects done under supervision of Prof. Caslav Brukner. It is divided into two main chapters. First part is based on the instrumental approach to quantum mechanics with the main objective to identify and mark the exclusive features of quantum theory in a broad class of probabilistic theories. The second part investigates the non-classical features of quantum mechanics including quantum statistics, quantum correlations and quantum simulations. It is fair to say that we still lack intuitive clear and broadly accepted physical principles that are a groundbasis of quantum theory. This shortfall is the main reason for todays coexistence of various interpretations of quantum theory, some of which even use mutually exclusive concepts. One of the main objectives in the first chapter was to specify theories that describe systems with fundamentally limited information content and therefore necessarily give a probabilistic description. With 'limited information content of the system' we understand a fundamental restriction on how much information about the state preparation can be decoded in the measurement. What was found is the whole hierarchy of theories that share this property with quantum and classical probability theory. The two theories separate from the full class of the probabilistic theories by adopting additional assumptions: locality and reversibility. With the 'locality' principle we assume that a global state of a composite system can be learned trough the statistics of individual systems, whereas the 'reversibility' principle states that any two pure state can be connected by a reversible transformation. Finally, quantum theory is separated by the requirement that the set of reversible transformations is continuous. In addition, one of the basic quantum concepts, the complementarity principle was investigated through so- called mutually unbiased bases relating them to the known mathematical problem of orthogonal Latin squares. A plausible classical description of quantum statistics requires counterintuitive concepts such as 'quantum non-locality' and contextuality'. The part of the second chapter deals with another question, i.e. the 'cost' in terms of resources for a plausible classical description. It was found that classical simulation of quantum statistics requires a polynomial number of classical resources (hidden-variables) in terms of number of measurement settings. Furthermore, the model confirms, in a proper limit, the known result that quantum mechanics is indeed the most optimal description of itself. Quantum correlations are responsible for 'quantum non-locality', as well as computational speedups and quantum information processing. There are examples of quantum information tasks that do not necessarily require entanglement. Therefore it is fair to say that 'quantumness' of the correlations is not equivalent to entanglement. The part of the second chapter deals with the question of 'non-classicality' of quantum correlations, captured by quantum discord. The main result gives an experimentally friendly necessary and sufficient condition for non-zero quantum discord. Furthermore the analysis of the resources in a mixed-state quantum computation scenario is provided and shows that the role of quantum discord in quantum information processing still remains unclear. Finally, the part of the last chapter investigates quantum simulations, both theoretically and experimentally. Quantum simulators provide a platform to mimic the dynamics of another quantum system that is infeasible for simulations on a classical computer. What is presented is the framework for the experimental realization of a small-size photonic quantum simulator that is capable of simulating a frustrated spin tetramer. The full dynamics and simulation of the ground state adiabatic evolution is achieved by employing entangled photon pairs, tunable quantum gates and measurement induced nonlinearities. (author)

    This text is for  a one semester graduate course in statistical theory and covers minimal and complete sufficient statistics, maximum likelihood estimators, method of moments, bias and mean square error, uniform minimum variance estimators and the Cramer-Rao lower bound, an introduction to large sample theory, likelihood ratio tests and uniformly most powerful  tests and the Neyman Pearson Lemma. A major goal of this text is to make these topics much more accessible to students by using the theory of exponential families. Exponential families, indicator functions and the support of the distribution are used throughout the text to simplify the theory. More than 50 ``brand name" distributions are used to illustrate the theory with many examples of exponential families, maximum likelihood estimators and uniformly minimum variance unbiased estimators. There are many homework problems with over 30 pages of solutions.

  10. Toward classifying unstable theories

    CERN Document Server

    Shelah, S

    1995-01-01

    The paper deals with two issues: the existence of universal models of a theory T and related properties when cardinal arithmetic does not give this existence offhand. In the first section we prove that simple theories (e.g., theories without the tree property, a class properly containing the stable theories) behaves ``better'' than theories with the strict order property, by criterion from [Sh:457]. In the second section we introduce properties SOP_n such that the strict order property implies SOP_{n+1}, which implies SOP_n, which in turn implies the tree property. Now SOP_4 already implies non-existence of universal models in cases where earlier the strict order property was needed, and SOP_3 implies maximality in the Keisler order, again improving an earlier result which had used the strict order property.

  11. G2 gauge theories

    CERN Document Server

    Maas, Axel

    2012-01-01

    QCD can be formulated using any gauge group. One particular interesting choice is to replace SU(3) by the exceptional group G2. Conceptually, this group is the simplest group with a trivial center. It thus permits to study the conjectured relevance of center degrees of freedom for QCD. Practically, since all its representation are real, it is possible to perform lattice simulations for this theory also at finite baryon densities. It is thus an excellent environment to test methods and to investigate general properties of gauge theories at finite densities. We review the status of our understanding of gauge theories with the gauge group G2, including Yang-Mills theory, Yang-Mills-Higgs theory, and QCD both in the vacuum and in the phase diagram.

This book provides a comprehensive and self-contained treatment of the theory, methods, and applications of nonlinear spectral theory. The only prerequisite for understanding this book is a modest background in functional analysis and operator theory. It is addressed to non-specialists who want to get an idea of the development of spectral theory for nonlinear operators in the last 30 years, as well as a glimpse of the diversity of the directions in which current research is moving.

  13. Constructor Theory of Life

    Neo-Darwinian evolution theory explains how organisms with their appearance of purposive design came into existence without being designed. The centrepiece of the explanation is a physical object, the gene, and the processes it undergoes: mainly, replication and natural selection. The compatibility of that theory with the laws of physics has been challenged, by claims that self-reproduction of living cells, essential to gene replication, is incompatible with quantum theory. Wigner, notably, argued that it would require design-bearing laws of physics. Here I show that self-reproduction is compatible with no-design laws of physics, in particular with quantum theory, by expressing self-reproduction, replication and the appearance of design clearly within physics, using the recently proposed constructor theory. I also show that aside from sufficient resources such as time and energy, the only requirement on the laws of physics for evolution to be possible is that they permit digital information.

  14. Nonlocal continuum field theories

    CERN Document Server

    2002-01-01

    Nonlocal continuum field theories are concerned with material bodies whose behavior at any interior point depends on the state of all other points in the body -- rather than only on an effective field resulting from these points -- in addition to its own state and the state of some calculable external field. Nonlocal field theory extends classical field theory by describing the responses of points within the medium by functionals rather than functions (the "constitutive relations" of classical field theory). Such considerations are already well known in solid-state physics, where the nonlocal interactions between the atoms are prevalent in determining the properties of the material. The tools developed for crystalline materials, however, do not lend themselves to analyzing amorphous materials, or materials in which imperfections are a major part of the structure. Nonlocal continuum theories, by contrast, can describe these materials faithfully at scales down to the lattice parameter. This book presents a unif...

    rii application of linear operators on a Hilbert space. We begin with a chapter on the geometry of Hilbert space and then proceed to the spectral theory of compact self adjoint operators; operational calculus is next presented as a nat­ ural outgrowth of the spectral theory. The second part of the text concentrates on Banach spaces and linear operators acting on these spaces. It includes, for example, the three 'basic principles of linear analysis and the Riesz­ Fredholm theory of compact operators. Both parts contain plenty of applications. All chapters deal exclusively with linear problems, except for the last chapter which is an introduction to the theory of nonlinear operators. In addition to the standard topics in functional anal­ ysis, we have presented relatively recent results which appear, for example, in Chapter VII. In general, in writ­ ing this book, the authors were strongly influenced by re­ cent developments in operator theory which affected the choice of topics, proofs and exercises. One ...

  17. Democratic Neutrino Theory

    2014-01-01

    New theory of neutrino masses and mixing is introduced. This theory is based on a simple S_3 symmetric democratic neutrino mass matrix, and predicts the neutrino mass spectrum of normal ordering. Taking into account the matter effect and proper averaging of the oscillations, this theory agrees with the variety of atmospheric, solar and accelerator neutrino data. Moreover, the absolute scale of the neutrino masses m of 0.03 eV is determined in this theory, using the atmospheric neutrino oscillation data. In case of tiny perturbations in the democratic mass matrix only one this scale parameter m allows to explain the mentioned above neutrino results, and the theory has huge predictive power.

    Full Text Available This is a reading of David Mulholland Drive through psychoanalytic approach of Lacan from the perspective of formation of fantasy and shifting identities. Lynch constructs his films consciously choosing his themes from the sub(versive/conscious side of human mind. Previous attempts to read Lynch's films are fixed around the idea that Lynch is using film genres to create postmodern pastiches. Mulholland Drive has been analyzed several times from different approaches ranging from gender (Love, 2004, narratology (Lentzner, 2005; McGowan, 2004; Cook, 2011. Elements of film noir, musical, caper films can be identified in Lynch’s films. This detailed textual analysis intends to rationalize Lynch’s narrative structure through Lacanian terms in reference to Zizekian terminology.

    Stricken by ALS at the age of 27, David Jayne slowly lost the ability to walk, to eat, to speak, and to breathe. With the assistance of home health professionals, medical technologies, and volunteers, he has managed to maintain as full a life as possible, participating in some of his children's activities and even managing, with great effort, to attend a football game. However, when he was the subject of a newspaper article, his home health coverage was dropped because he didn't meet the federal definition of "homebound." This is the story of how he took on the political establishment single-handedly, and eventually realized a victory that has the potential of helping thousands of people in similar situations to no longer be imprisoned at home.

    “There is no alternative”, Margaret Thatcher infamously stated as an argument for capital- ism in its most liberal form – despite its obvious shortcomings – as the only relevant eco- nomic system in advanced and modern democracies. With the demise of state socialism in the 1990s for a time it seemed like she had been right, and more and more in urban planning and design today, the market forces seem at least as important as the human condition. But why is it meant to be unrealistic to propose decent housing for all or an urbanism that puts the needs of people above those of profit? And what is inconceivable about an urbanism that is no longer based around private property, or that emphasises the pleasures and joys of living? In this e-mail conversation the British geographer David Pinder makes a defence for utopian thinking as a means to imagine alternatives that seem impossible today but may be possible tomorrow

  6. Pattern/randomness. Il rapporto fra testo e lettore in Infinite Jest di David Foster Wallace

    Ugo Panzani

    2013-11-01

    Full Text Available David Foster Wallace questioned the previous literary tradition usually defined as “postmodern” through his narrative and non-fiction production. Following Katherine Hayles, it is possible to consider the decreasing prominence of the presence/absence dialectic typical of deconstructionism and postmodernism and, on a parallel plane, the increasing relevance of a pattern/randomness dialectic. From this point of view, one might argue, many postmodern fictions merely diagnosed the presence of a “technological sublime”, without proposing cognitive solutions to actively deal with it. Through a comparison between some key aspects of neural networks and the narrative structure of Infinite Jest (1996, the primary aim of this contribution is to understand how Wallace's novel may be considered as a literary device that helps the reader to become the manufacturer of new cognitive patterns, by processing and selecting information from the huge amount of data contained in the novel.

    2010-12-01

    In this article, David Bittner explodes the myth, restated in Brideshead Revisited (1945), that Polynesians are "happy and harmless." He does so for the same reason that Evelyn Waugh does: "the grim invasion of trader, administrator, missionary, and tourist" has changed all that (p. 174). Touring Hawaii in July of '09, Bittner was interested to discover some unusual bits of American heritage, but saddened to see how "civilization" and "Americanization" actually seem to have eroded the Hawaiian people's rights to life, liberty, and the pursuit of happiness. Bittner's dual religious heritage-Judaism by birth and upbringing and Catholicism by choice in mid-life-has given him the perspective to apply the lessons of Hawaiian history to his own personal issues, particularly forgiveness.

    We construct classes of superconformal theories elements of which are labeled by punctured Riemann surfaces. Degenerations of the surfaces correspond, in some cases, to weak coupling limits. Different classes are labeled by two integers ( N, k). The k = 1 case coincides with A N - 1 theories of class and simple examples of theories with k > 1 are orbifolds of some of the A N - 1 class theories. For the space of theories to be complete in an appropriate sense we find it necessary to conjecture existence of new strongly coupled SCFTs. These SCFTs when coupled to additional matter can be related by dualities to gauge theories. We discuss in detail the A 1 case with k = 2 using the supersymmetric index as our analysis tool. The index of theories in classes with k > 1 can be constructed using eigenfunctions of elliptic quantum mechanical models generalizing the Ruijsenaars-Schneider integrable model. When the elliptic curve of the model degenerates these eigenfunctions become polynomials with coefficients being algebraic expressions in fugacities, generalizing the Macdonald polynomials with rational coefficients appearing when k = 1.

    The time has now come when graph theory should be part of the education of every serious student of mathematics and computer science, both for its own sake and to enhance the appreciation of mathematics as a whole. This book is an in-depth account of graph theory, written with such a student in mind; it reflects the current state of the subject and emphasizes connections with other branches of pure mathematics. The volume grew out of the author's earlier book, Graph Theory -- An Introductory Course, but its length is well over twice that of its predecessor, allowing it to reveal many exciting new developments in the subject. Recognizing that graph theory is one of several courses competing for the attention of a student, the book contains extensive descriptive passages designed to convey the flavor of the subject and to arouse interest. In addition to a modern treatment of the classical areas of graph theory such as coloring, matching, extremal theory, and algebraic graph theory, the book presents a detailed ...

    The gravity theories provide an alternative way to explain the current cosmic acceleration without invoking a dark energy matter component used in the cosmological modeling in the framework of general relativity. However, the freedom in the choice of the functional forms of gives rise to the problem of the degeneracy among these gravity theories on theoretical and (or) observational grounds. In this paper we examine the question as to whether the future dynamics can be used to break the degeneracy between gravity theories by investigating the dynamics of spatially homogeneous and isotropic dust flat models in two gravity theories, namely the well-known gravity and another by Aviles et al., whose motivation comes from the cosmographic approach to gravity. We perform a detailed numerical study of the dynamics of these theories taking into account the recent constraints on the cosmological parameters made by the Planck Collaboration. We demonstrate that besides being useful for discriminating between these two gravity theories, the future dynamics technique can also be used to determine the finite-time behavior as well as the fate of the Universe in the framework of these gravity theories. There also emerges from our analysis the result that one still can have a dust flat FLRW solution with a big rip, if gravity is governed by . We also show that FLRW dust solutions with do not necessarily lead to singularities.

  17. Gauge field theory

    International Nuclear Information System (INIS)

    This lecture is devoted to the discussion of gauge field theory permitting from the single point of view to describe all the interactions of elementary particles. The authors used electrodynamics and the Einstein theory of gravity to search for a renormgroup fixing a form of Lagrangian. It is shown that the gauge invariance added with the requirement of the minimum number of arbitraries in Lagrangian fixes unambigously the form of the electromagnetic interaction. The generalization of this construction for more complicate charge spaces results in the Yang-Mills theory. The interaction form in this theory is fixed with the relativity principle in the charge space. A quantum scheme of the Yang-Mills fields through the explicit separation of true dynamic variables is suggested. A comfortable relativistically invariant diagram technique for the calculation of a producing potential for the Green functions is described. The Ward generalized identities have been obtained and a procedure of the elimination of ultraviolet and infrared divergencies has been accomplished. Within the framework of QCD (quantum-chromodynamic) the phenomenon of the asymptotic freedom being the most successful prediction of the gauge theory of strong interactions was described. Working methods with QCD outside the framework of the perturbation theory have been described from a coupling constant. QCD is represented as a single theory possessing both the asymptotical freedom and the freedom retaining quarks

    The Point of View by Gregory Pauly, David Hillis, and David Cannatella misrepresents the motives and activities of the anuran subcommittee of the Scientific and Standard English Names Committee, contains a number of misleading statements, omits evidence and references to critical literature that have already rejected or superseded their positions, and cloaks the limitations of their nomenclatural approach in ambiguous language. Their Point of View is not about promoting transparency in the process of constructing the English Names list, assuring that its taxonomy is adequately reviewed, or promoting nomenclatural stability in any global sense. Rather, their Point of View focuses in large part on a single publication, The Amphibian Tree of Life, which is formally unrelated to the Standard English Names List, and promotes an approach to nomenclature mistakenly asserted by them to be compatible with both the International Code of Zoological Nomenclature and one of its competitors, the PhyloCode.

In every area, pre-theory concepts give broad directions for investigation: are the movements of heavenly bodies affected by the existence of other heavenly bodies? Post-theory concepts add precision and predictability. The mistake occurs when a successful theory like Newton’s demands that its peculiar and precise theory-imbedded concept forbids competing ...
