David Hume's Monetary Theory Revisited: Was He Really a Quantity Theorist and an Inflationist?  

Science.gov (United States)

David Hume's monetary theory has been controversial since its formulation. Lately, the focus has been on Hume's alleged misapplication of the quantity theory of money. While he appears to subscribe to a simple quantity theory with money neutrality, in a famously contested passage in the essay Of Money, he violates the neutrality condition by…

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

Science.gov (United States)

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.

David Hilbert's lectures on the foundations of physics 1915-1927 relativity, quantum theory and epistemology  

CERN Document Server

A single system of economic governance - capitalism - prevails in the world today, both in theory and in practice. Yet there is neither a standard definition of capitalism nor a theory of how it works. Moreover, the most common conception of capitalism is that of a one-level system governed by markets, i.e., supply and demand, where many socioeconomic externalities are ignored. The purpose of this book is to counter this conception, showing that capitalism is more than markets. In fact, capitalism shares many parallels with everyday organized sports, in that both are indirect, three-level syst

We put into a general setting a technique of Rene' David (see "A Very Absolute Pi^1_2 Singleton, Annals of Pure and Applied Logic, 1982) to show that for S a Sigma^1_1 statement quantifying over subclasses of V of a special form, there is a stronger Sigma^1_3 statement quantifying over reals which can be forced over any model of S. Then I mention some application to Pi^1_2 Singletons and to Sigma^1_3 absoluteness.

Integral Evolution: An Interview with David Loye  

Directory of Open Access Journals (Sweden)

Full Text Available David Loye is one of those people that the longer you get to know them the more you begin todiscover a bit of their depth and breadth of perspective and creativity in the world. Hispublications speak for themselves. His network with leading scientists and thinkers around theworld is equally impressive.Actually, my first contact was with David’s wife, Riane Eisler, author of the Chalice and theBlade (among other books written with and without David. Despite the fact that they live overthe hill from me, I did not meet her face to face right away. Rather, I interviewed her over thetelephone for the Integral Leadership Review, which I publish and edit. When I first approachedher about doing the interview she suggested that I should interview David, but I did not knowDavid Loye’s work at all. In that interview I discovered more about Riane’s work and the extentof their partnership. In fact, they are prime movers of a partnership approach to leadership thatthey promote through a nonprofit center and in a Master’s program at the California Institute ofIntegral Studies in San Francisco.My conversation with Riane piqued my curiosity about David’s work and I bought one of hisbooks, Darwin’s Lost Theory of Love. Here I found evidence of the extraordinary scope anddepth of David’s work that made him a natural candidate for an interview. The only questionwas would I use it in Integral Leadership Review or in Integral Review: such is the quality of hisinterests and intellect.Before doing the interview, I borrowed a copy of one of David’s earlier books. When I went totheir house to pick it up I met them both. They are quite a team and I recommend their work toall.

David Crighton 1942 2000  

Science.gov (United States)

David Crighton was struck down by cancer in his fifty-eighth year. He was then at the height of his career and was one of the most admired personalities in fluid mechanics. He had specialized in wave theory, helping to understand and solve problems of practical importance using the full power of mathematical method. Efforts to control the sound and vibration caused by unsteady flow were never far from his thinking, and Crighton's contribution to those efforts has changed significantly the way the subject is viewed. Having first attracted him into the field and never losing my interest in the way he was influencing it, it is natural that I should comment on the technical developments while looking back on Crighton's professional life. The subject has changed a great deal and there are now many more researchers involved in its study, many of whom rely on techniques that Crighton pioneered really powerful mathematical methods. But the basic problems remain: powerful flows are noisy.

Memories of David Kirzhnits  

Science.gov (United States)

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."...

David Bowie's Hauntology  

DEFF Research Database (Denmark)

David Bowie's now-defunct rock-opera trilogy's first installment 1. Outside is filled with uncanny mediations of rock music's chameleon. 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 voiceand 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.

Paranoid, moi? : Erasing David  

DEFF Research Database (Denmark)

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.

David Liberman's legacy.  

Science.gov (United States)

This article presents, in the author's own vision, his attempt to consider (and update) the work of an original thinker of contemporary psychoanalysis (in the present). Following a short overview of his biographical data and distinctive traits as maestro and man, it then tries to capture the implications and panoramic vision of Liberman's work, the prevailing questions and problems of psychoanalysis to which it responds. In the author's opinion this involves a serious attempt to systematize clinical psychoanalysis on the basis of singularity and of tolerance to human diversity, with the greatest precision and scientific rigour admitted by the psychoanalytic discipline - avoiding cliché on the one hand and what we might call the mystification of the Oracle on the other. The successive stages of Liberman's production are indicated in terms of the auxiliary disciplines (communication theory, semiotics and linguistics) which he used for his ever more precise systematization of clinical psychoanalysis finally leading to his proposals on 'style' and his vision of the psychopathology of over-adaptation and psychosomatic instances. Other concepts which this paper highlights are: Liberman's conception of analytic dialogue as framed by human interaction; his theorization which stems from this particular empirical base making use of 'operational definitions' and 'intermediary formulations'; his operational definition of transference; and the inclusion of setting inside the 'analytic situation'.

The Art of David Tudor  

Science.gov (United States)

From the library at the Getty Research Institute, The Art of David Tudor is a great example of effective presentation of highlights from rich library and archival collections on the Web. The site complements a symposium held at the Getty Research Institute in 2001: "The Art of David Tudor: Indeterminacy and Performance in Postwar Culture". Born in 1926, Tudor became an internationally known pianist in the traditional arena, but gravitated to more experimental music in the 1940s, and composed and performed experimental electronic music in the 1960s and 1970s. Tudor's major works were produced collaboratively, with colleagues including John Cage and Merce Cunningham, Jackie Matisse, Bill Viola, and Karlheinz Stockhausen. The site includes a section on Tudor's collaborators; biographies and links to additional resources on over 35 artists who worked or performed with Tudor. Other main sections are: Audio and Video, where visitors can watch and listen to excerpts of Tudor's works (most of the full versions are held by the Getty Research Institute); Image Library, featuring pictures of Tudor, as well as documents such as scores and letters; a section on the symposium, and a biography of Tudor.

David Owen Williams (1944 - 2006)  

CERN Multimedia

Many people, not only at CERN but also throughout the world, were saddened to learn that their friend and colleague David Williams had passed away in the early hours of Tuesday 24 October. His death came after a year of fighting cancer with all of his usual determination and optimism. Even days before the end he was still welcoming to visitors, and was alert and interested in all their news. Born in 1944, David came to CERN from the University of Cambridge in 1966, with a degree in Physics and Computer Science. Joining what at the time was called the Documents and Data (DD) Division, in the earlier part his career he worked first on software for analysis of bubble chamber photographs, subsequently leading the group that supported experiments with 'hybrids' of bubble chambers and electronic detectors and then the group supporting online computing in experiments. He thus witnessed all of the enormous changes that took place in particle physics as the era of bubble chambers came to an end and the availability ...

Jacques-Louis David: Empire to Exile  

Science.gov (United States)

Deftly combining art and history, this site from the Getty presents the works of painter Jacques-Louis David, "Image-maker to Napoleon". Although there are not a huge number David's paintings and drawings in the Web exhibition, those present are extensively researched. For example, a portrait of Suzanne Le Peletier de Saint-Fargeau, daughter of an assassinated revolutionary who came to be called "Mademoiselle Nation" during the French Revolution, is accompanied by both a video and a discussion, relating her political history and analyzing the style and iconography with which David depicts it. In the section on Napoleon, visitors can zoom in on details of David's The Emperor Napoleon in His Study at the Tuileries 1811-1812, read a biography of Napoleon, view several other studies and paintings of the French emperor, and read about his relationship to David.

Las biografías criminales de David Viñas / David Viñas' Criminal Biographies  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish 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 mos [...] trar 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. Abstract in english In his early years as storyteller, David Viñas wrote-under the pseudonym of Pedro Pago-three novels about famous Argentine bandits: Chicho Grande, Chicho Chico and Mate Cocido. Published in 1953 in the collection Crime, these novels have received almost no attention. This paper intends to show that [...] these texts have some fundamental features and elements of Viñas' narrative work and screenplays of the subsequent years. Also, the three stories are significant from the perspective of the history of detective fiction in Argentina. In contrast to the history of the genre elaborated by Walsh the same year (1953), from a point of view that places in the center the classical whodunit story, this collection prove the existence of a different tradition, which pay less attention to the mystery and deductive resolution than to the criminal biography and its social determinations.

A Star of David catenane  

Science.gov (United States)

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.

David Hubel and Torsten Wiesel.  

Science.gov (United States)

While attending medical school at McGill, David Hubel developed an interest in the nervous system during the summers he spent at the Montreal Neurological Institute. After heading to the United States in 1954 for a Neurology year at Johns Hopkins, he was drafted by the army and was assigned to the Neuropsychiatry Division at the Walter Reed Hospital, where he began his career in research and did his first recordings from the visual cortex of sleeping and awake cats. In 1958, he moved to the lab of Stephen Kuffler at Johns Hopkins, where he began a long and fruitful collaboration with Torsten Wiesel. Born in Sweden, Torsten Wiesel began his scientific career at the Karolinska Institute, where he received his medical degree in 1954. After spending a year in Carl Gustaf Bernhard's laboratory doing basic neurophysiological research, he moved to the United States to be a postdoctoral fellow with Stephen Kuffler. It was at Johns Hopkins where he met David Hubel in 1958, and they began working together on exploring the receptive field properties of neurons in the visual cortex. Their collaboration continued until the late seventies. Hubel and Wiesel's work provided fundamental insight into information processing in the visual system and laid the foundation for the field of visual neuroscience. They have had many achievements, including--but not limited to--the discovery of orientation selectivity in visual cortex neurons and the characterization of the columnar organization of visual cortex through their discovery of orientation columns and ocular-dominance columns. Their work earned them the Nobel Prize for Physiology or Medicine in 1981, which they shared with Roger Sperry. PMID:22841302

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

DEFF Research Database (Denmark)

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).

LA METAFÍSICA DE LAS LEYES DE LA NATURALEZA DE DAVID LEWIS / David Lewis's Metaphysics of Laws of Nature  

Scientific Electronic Library Online (English)

Full Text Available SciELO Colombia | Language: Spanish Abstract in spanish En el artículo se pretende presentar una concepción adecuada de la teoría de David Lewis acerca de la metafísica de las leyes de la naturaleza. Para esto, se examinan algunos de los elementos de la concepción metafísica de Lewis acerca del mundo, los cuales constituyen el contexto en el cual plantea [...] su teoría acerca de las leyes de la naturaleza. Este examen permite sostener que en la teoría de Lewis acerca de las leyes hay un componente realista y uno no realista. Según Lewis, una generalización es una ley de la naturaleza si y solo si es verdadera y forma parte del mejor sistema teórico acerca del mundo. Una generalización verdadera es verdadera en virtud del componente realista: una regularidad en los hechos particulares. Y una generalización verdadera puede ser una ley o no en virtud del componente no realista: el mejor sistema teórico acerca del mundo. Si una generalización verdadera forma parte del mejor sistema teórico es una ley de la naturaleza, si no forma parte, entonces sólo es una regularidad verdadera. Una vez presentada la teoría de Lewis, se examinará en qué medida es satisfactoria. Para esto, se verá si la teoría da cuenta o no de algunas de las opiniones más frecuentes acerca de las leyes de la naturaleza. Abstract in english In this paper I will try to present an appropriate conception of David Lewis's theory about metaphysics of laws of nature. In order to achieve this, I will study some of the elements of Lewis's metaphysical conception about the world, which form the context in which he proposes his theory about laws [...] of nature. This study allows me to hold that in Lewis's theory about laws of nature there is one realistic component and there is another that is not realistic. According to Lewis, a generalization is a law of nature iff this is true and a part of the best theoretical system about the world. A true generalization is true by virtue of the realistic component: a regularity in particular facts. And a true generalization can be or cannot be a law by virtue of the component that is not realistic: the best theoretical system about the world. If a true generalization is included in that system, this is a law of nature. If a true generalization is not included in that system, this is just a true generalization. After presenting Lewis's theory, I will examine how good this theory is. In order to achieve this, I will study if the theory accounts for some of the most extended opinions about laws of nature.

Obituary: David Stanley Evans, 1916-2004  

Science.gov (United States)

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

Henry David Thoreau: Literary Transcendentalism  

Directory of Open Access Journals (Sweden)

Full Text Available During the mid-19th century, New England was experiencing Transcendentalism as a religious, philosophical and literary movement. Despite being inspired by German and British Romanticism, due to its nature which incorporated true notions of American individualism, Transcendentalism was a distinct American movement. Individuals like Thoreau constructed the political dimension of Transcendentalism by putting their transcendentalist beliefs into action by disobeying the government. The true transcendentalist movement was rooted in various influential factors including but not limited to slavery and the civil war, women’s rights, growing industrialism and social gap.Thoreau’s writings are a fit expression of a life based on high ideals and aspirations which integrates integrity and morality. He tends to spent words in pursuit of spiritual development, and it is due to the universal truth behind the particular and the personal that he conveys transcendent meaning. The present article triesto have a closer look at Thoreau’s transcendental literary theory and the way it was presented in his works of art. The article started with proposing a research question regarding the basis of Thoreau’s Transcendental literary thinking and how he presented it in his writings which he regarded as interconnectionamong physical, intellectual, and spiritual worlds.

No romance, A mulher foge, de David Grossman, como em Homero, a realidade da guerra contrapõe-­se à realidade das pessoas comuns e, assim, separa, em um vasto abismo, as experiências deste e daquele lado. Ao contrário do que acontece na Bíblia, e também na Ilíada, não há, nas guerras do romance, qualquer tipo de crença divina, seja ela de molde pagão, seja ela de caráter retributivo, conforme a teologia bíblica.

Obituary: David L. Band (1957-2009)  

Science.gov (United States)

David L. Band, of Potomac Maryland, died on March 16, 2009 succumbing to a long battle with spinal cord cancer. His death at the age of 52 came as a shock to his many friends and colleagues in the physics and astronomy community. Band showed an early interest and exceptional aptitude for physics, leading to his acceptance at the Massachusetts Institute of Technology as an undergraduate student in 1975. After graduating from MIT with an undergraduate degree in Physics, Band continued as a graduate student in Physics at Harvard University. His emerging interest in Astrophysics led him to the Astronomy Department at the Harvard Smithsonian Center for Astrophysics (CfA), where he did his dissertation work with Jonathan Grindlay. His dissertation (1985) entitled "Non-thermal Radiation Mechanisms and Processes in SS433 and Active Galactic Nuclei" was "pioneering work on the physics of jets arising from black holes and models for their emission, including self-absorption, which previewed much to come, and even David's own later work on Gamma-ray Bursts," according to Grindlay who remained a personal friend and colleague of Band's. Following graduate school, Band held postdoctoral positions at the Lawrence Livermore Laboratory, the University of California at Berkeley and the Center for Astronomy and Space Sciences at the University of California San Diego where he worked on the BATSE experiment that was part of the Compton Gamma Ray Observatory (CGRO), launched in 1991. BATSE had as its main objective the study of cosmic gamma-ray bursts (GRBs) and made significant advances in this area of research. Band became a world-renowned figure in the emerging field of GRB studies. He is best known for his widely-used analytic form of gamma-ray burst spectra known as the "Band Function." After the CGRO mission ended, Band moved to the Los Alamos National Laboratory where he worked mainly on classified research but continued to work on GRB energetics and spectra. When NASA planned two new follow-up missions to CGRO, the Swift and Fermi observatories, Band seized an opportunity in 2001 to join the staff of the Fermi Science Support Center at the NASA Goddard Space Flight Center in Greenbelt Maryland. He was hired as the lead scientist for user support functions and to help to define and implement planning for the 2008 launch of the Fermi spacecraft. He brought a high level of energy and enthusiasm to the job, becoming in many ways the heart and soul of that organization. Neil Gehrels, the Goddard Astroparticle Physics Division Director and a Fermi deputy project scientist notes that "David was the perfect person for community support, with this outgoing personality and deep knowledge of astrophysics." Band also became an important member of the Fermi science team; despite his failing health, he actively contributed to the first Fermi gamma-ray burst publication as well as making important contributions to the burst detection and data analysis techniques. Additionally, Band was known as a great communicator and mentor. He supervised a PhD student at UCSD who has subsequently been appointed to a faculty position. At Goddard, Band was an integral part of the weekly scientific discussion groups within the gamma-ray astronomy group and he would always find the time to share his knowledge and expertise with new postdoctoral fellows and senior scientists alike. He was also involved with planning the EXIST mission, a candidate for a future NASA mission. He will be greatly missed by his many friends and colleagues within the Fermi mission and the high-energy astrophysics community.

Do Père David's Deer Lose Memories of Their Ancestral Predators?  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Whether prey retains antipredator behavior after a long period of predator relaxation is an important question in predator-prey evolution. Père David's deer have been raised in enclosures for more than 1200 years and this isolation provides an opportunity to study whether Père David's deer still respond to the cues of their ancestral predators or to novel predators. We played back the sounds of crows (familiar sound) and domestic dogs (familiar non-predators), of tigers and wolves (ancestra...

Physics Nobel prize 2004: Surprising theory wins physics Nobel  

CERN Multimedia

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...

Clássicos versus Keynes: a abordagem formal de David Champernowne

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).

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.

Conhecimento e natureza na filosofía da David Hume

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. Abstract in english The philosophy of David Hume was for a long time conceived as a skeptical philosophy. 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.

David Bohm la physique de l'infini  

CERN Document Server

Les idées de David Bohm, indépendamment du scepticisme de ses collègues les plus traditionalistes, ont profondément influencé la physique du siècle dernier et ouvert une porte à la physique du nouveau millénaire. Grâce aussi aux contacts qu'il sut nouer avec des chercheurs d'autres branches du savoir, ses idées ont été accueillies avec beaucoup d'enthousiasme par les neuroscientifiques, les philosophes, les théologiens, les psychologues, les sociologues, les poètes, les artistes et les éducateurs. David Bohm avait peut-être pressenti qu'il existe une "physique de l'âme" et avec elle il voulait tracer un nouveau chemin pour une humanité à la dérive.

INTRODUCTION: David Sherrington as a mentor of young scientists  

Science.gov (United States)

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

Chella David: a lifetime contribution in translational immunology.  

Science.gov (United States)

Immunology, like most scientific disciplines, is filled with buzz words. One such buzz word or term has been coined "translational immunology". Indeed, translational research is amongst the most popular expressions used to justify the use of basic research in the hopes that such research will lead to solutions to clinical problems. In fact, no such justification is needed and some of the most important observations in clinical medicine have been derived from basic science; basic science that had no idea at its time of its usefulness in clinical medicine. This special issue is devoted to Chella David. Chella's contributions in immunology have been legion. Before inbred mice became popular, long before multi-million dollar companies were developed to develop such models, Chella David was hard at the bench studying the genetics of the murine immune system and the importance of such mouse models in autoimmune diseases. Importantly, Dr. David provided animals without strings, without the burdens of MTAs, that now impede research. Chella has been generous with his time, with his reagents, and has been a caring and devoted mentor to generations of students. This issue is part of our series to recognize autoimmunologists and dedicated themes that include papers in multiple disciplines of immunology, but especially are focused on cutting-edge applications that will improve clinical therapeutics. Chella David, at age 75, is an athlete in immunology and still keeps going with the same enthusiasm as manifest as a young post-doc. PMID:21621385

Monstrosity, Anxiety and the Real: Representations of the Victorian Metropolis in David Lynch's The Elephant Man  

Directory of Open Access Journals (Sweden)

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.

Fairness and Respect in Obesity Prevention Policies: A Response to David Buchanan  

Directory of Open Access Journals (Sweden)

Full Text Available In his response to our article (1,2, David Buchanan introduces some useful and important distinctions in the concepts of equality and autonomy. He highlights, for example, the distinction between inequality and inequity, which captures the insight that not all differences between people are unjust. Unjust inequalities are a subset of differences between people, and theories of justice can be defined by how they determine which of these differences are unjust. In addition, he points out that autonomy is not simply a matter of negative liberty, but also about a positive capacity to act. This understanding of autonomy is consistent with the account we offered in the paper, which underlines the importance of both the capacity to understand available options, and the capacity to act on the choices that one makes.

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

Directory of Open Access Journals (Sweden)

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.

A new gene mapping resource: Interspecies hybrids between Pere David`s deer (Elaphurus davidianus) and red deer (Cervus elaphus)  

Energy Technology Data Exchange (ETDEWEB)

Three male F{sub 1} hybrids between Pere David`s deer and red deer were mated to red deer to produce 143 backcross calves. The pedigrees are a rare example of a fertile hybrid between evolutionarily divergent species. We examined the use of these families for genetic mapping of evolutionarily conserved (Type I) loci by testing for genetic linkage between five species-specific protein variants and 12 conserved DNA probes. Two probes were homologous, and the remainder syntenic, to the protein coding loci in cattle or humans. Using six restriction enzymes, each DNA probe detected one or more restriction fragments specific to Pere David`s deer. Linkage analyses among the species-specific variants placed the loci into four linkage groups within which linkage between adjacent loci and gene order was supported by a LOD > 3. Southern and protein analysis of LDHA and ALB provided identical segregation data. These linkage groups were consistent with the cattle gene map and provide new information for comparing the gene maps of ruminants, humans and mice. The deer hybrids are an important new resource that can contribute to the comparative analysis of the mammalian genome. 68 refs., 2 figs., 2 tabs.

Obituary: David Fulmer Bender, 1913-2004  

Science.gov (United States)

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

Pupazzi di neve. David Lynch fotografo e l’"Unheimliche"  

Directory of Open Access Journals (Sweden)

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.

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

EDITORIAL: Van der Waals interactions in advanced materials, in memory of David C Langreth Van der Waals interactions in advanced materials, in memory of David C Langreth  

Science.gov (United States)

The past decade has seen a dramatic rise in interest in exploring the role that van der Waals (vdW) or dispersion forces play in materials and in material behavior. Part of this stems from the obvious fact that vdW interactions (and other weak forces, such as Casimir) underpin molecular recognition, i.e., nature's approach to search for a match between genes and anti-genes and hence enable biological function. Less obvious is the recognition that vdW interactions affect a multitude of properties of a vast variety of materials in general, some of which also have strong technological applications. While for two atom- or orbital-sized material fragments the dispersive contributions to binding are small compared to those from the better known forms (ionic, covalent, metallic), those between sparse materials (spread over extended areas) can be of paramount importance. For example, an understanding of binding in graphite cannot arise solely from a study of the graphene layers individually, but also requires insight from inter-sheet graphene vdW bonding. It is the extended-area vdW bonding that provides sufficient cohesion to make graphite a robust, naturally occurring material. In fact, it is the vdW-bonded graphite, and not the all-covalently bonded diamond, that is the preferred form of pure carbon under ambient conditions. Also important is the understanding that vdW attraction can attain a dramatic relevance even if the material fragments, the building blocks, are not necessarily parallel from the outset or smooth when viewed in isolation (such as a graphene sheet or a carbon nanotube). This can happen if the building blocks have some softness and flexibility and allow an internal relative alignment to emerge. The vdW forces can then cause increasingly larger parts of the interacting fragments to line up at sub-nanometer separations and thus beget more areas with a sizable vdW bonding contribution. The gecko can scale a wall because it can bring its flexible hairs sufficiently close to any corrugated—and/or any smooth—surface and thus enforce a strong vdW-type adhesion; it exploits what is then essentially a contact force (dominated by the attraction exerted in the near-surface regions) to defy the pull of gravity on its own bulk. This Journal of Physics: Condensed Matter special issue is dedicated to the memory of David C Langreth. David is a dearly missed friend and mentor who inspired many of us. He was an outstanding condensed matter theorist and a scholar who greatly influenced us through his many-particle-physics based insights into density functional theory (DFT), surface science and related areas. His seminal works range from conserving formulations of interacting nonequilibrium transport [1] and formal-scattering theory [2] to an explicit formulation [3] of the exact DFT exchange-correlation energy in the adiabatic connection formula (ACF), the latter also being derived independently by Gunnarsson and Lundqvist [4]. David's portfolio also includes an analysis [5] that helped catalyze and guide the development of DFT from the local-density approximation (LDA) to the formulations of generalized gradient approximations (GGAs). Another salient contribution of David's is in the area of vdW interactions in materials. He was a key architect of the vdW density functional (vdW-DF) method [6, 7]. This method was developed in a long-standing Rutgers-Chalmers collaboration between David's group and that of Bengt I Lundqvist, later extending to a wider group of researchers on both sides of the Atlantic. Plasmons are collective excitations that depend on electron-density variation. The plasmon response can be seen as defining the nature of the LDA [4] and their description can thus also be seen as contributing to the success of GGA. The vdW-DF method is a regular constraint-based density functional (for ground-state DFT) which is derived within the ACF framework and which emphasizes the electrodynamical nature of the coupling between these collective plasmon excitations. The vdW-DF method thus seeks to utilise the implicit

David Elijah Packer: cluster variables, meteors and the solar corona  

CERN Document Server

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.

Waltz's Theory of Theory  

DEFF Research Database (Denmark)

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.

No correlation between neonatal fitness and heterozygosity in a reintroduced population of Père David's deer  

Directory of Open Access Journals (Sweden)

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].

Capacity theory on algebraic curves  

CERN Document Server

Capacity is a measure of size for sets, with diverse applications in potential theory, probability and number theory. This book lays foundations for a theory of capacity for adelic sets on algebraic curves. Its main result is an arithmetic one, a generalization of a theorem of Fekete and Szegö which gives a sharp existence/finiteness criterion for algebraic points whose conjugates lie near a specified set on a curve. The book brings out a deep connection between the classical Green's functions of analysis and Néron's local height pairings; it also points to an interpretation of capacity as a kind of intersection index in the framework of Arakelov Theory. It is a research monograph and will primarily be of interest to number theorists and algebraic geometers; because of applications of the theory, it may also be of interest to logicians. The theory presented generalizes one due to David Cantor for the projective line. As with most adelic theories, it has a local and a global part. Let /K be a smooth, complet...

D. M. Armstrong on the Identity Theory of Mind  

Directory of Open Access Journals (Sweden)

Full Text Available The Identity theory of mind occupies an important place in the history of philosophy. This theory is one of the important representations of the materialistic philosophy. This theory is known as "Materialist Monist Theory of Mind". Sometimes it is called "Type Physicalism", "Type Identity" or "Type-Type Theory" or "Mind-Brain Identity Theory". This theory appears in the philosophical domain as a reaction to the failure of Behaviourism. A number of philosophers developed this theory and among them U. T. Place, J. J. C. Smart, Herbert Feigl, D. Armstrong, and David Lewis are prominent. The main thesis of this theory is-states and processes of the mind are identical to states and processes of the brain. In this paper, I am trying to delineate the view of Armstrong on the nature of mind.

David Rumsey Map Collection: 1979 California Water Atlas  

Science.gov (United States)

In a state where water has been a serious public policy issue for many decades, creating an atlas of water resources and usage was considered an important undertaking. That's just what happened in 1979 when the state of California released this groundbreaking atlas. After its release that year, it was hailed as a major achievement in cartography and scientific endeavor from a variety of groups and organizations, including the Quarterly Review of Biology and the California Historical Quarterly. Recently David Rumsey and Cartography Associates scanned the entire original volume in all of its detailed glory, and it is now available for general use here. The atlas can be viewed in a number of different formats, including pdf files or an online book, courtesy of the Internet Archive. Plates from the atlas include "Crop Patterns and Applied Water", "Annual Runoff and Seasonality", and "Measured and Unimpaired Streamflows". It's a masterful work, and one that visitors will want to let friends know about.

Although Dave resided at an oceanographic institution for almost his entire professional career, the great majority of his work concerned atmospheric measurements; his own account of his work [Keeling, 1998] makes scant reference to his ocean science papers. But those relatively few oceanic papers, and more importantly his intense personal interest and unimpeachable reputation for classic measurement, had enormous impact. It is possible to trace Dave's influence on oceanic measurement through the course of five decades, and over that time, our understanding has grown enormously. The following is a somewhat personal account, but Dave so influenced the careers of the small group of ocean CO2 scientists that have led the way that any one of them would write a similar account.

Infinite potential the life and times of David Bohm  

CERN Document Server

Throughout his life, David Bohm felt himself to be different, and this was reflected in his lifestyle and in his physics. His life was one of unfulfilled searching. If one compares mainstream physics to the church, with a solid hierarchy of cardinals, archbishops and bishops, Bohm was an ascetic hermit who would occasionally come in from the wilderness with a compelling message, only to disappear again. Bohmian quantum mechanics is not part of mainstream physics, but for those who do cross over, like John Bell, the commitment can be rewarding. In the post-war 'Un-American Activities' purge, Bohm lost a prestigious job at Princeton and t emporarily his US citizenship, and his nomadic career took him to Brazil, Israel and Bristol before he finally settled in London's Birkbeck College. A sensitive-written book about a gifted, unusual and sometimes provocative figure. The interaction between Bohm and Oppenheimer is especially interesting, while Bohm's later life was bizarre.

Observation on the recent examination of bones from St David's Cathedral.  

Science.gov (United States)

Bones discovered in 1866 walled up in St David's Cathedral, West Wales were thought possibly to be those of St David and his companion St Justinian, both of whom died in the late 6th or early 7th century. Examination and radio carbon dating of the bones suggested that these were not from St David nor St Justinian. Some of the bones could be the remains of St Caradoc, a 12th century hermit. It is likely, however, that the bones are remains of clergy who, for reasons not yet understood, were re-interred into the wall. PMID:10689864

Abstract Clostridium perfringens is an important pathogen causing sudden death syndrome, necrotic enteritis, and gas gangrene in ruminants, especially some deer species. Père David's deer (Elaphurus davidianus) is one of the world's rare species and is an endangered and protected species in China. Some Père David's deer in the Chinese Shishou Père David's Deer Preserve died due to C. perfringens infection. We investigated the toxin types and C. perfringens enterotoxin-positive (cpe(+)) strains of isolated C. perfringens in Père David's deer in China. We collected 155 fecal samples from the Beijing Nanhaizi Père David's Deer Park and the Jiangsu Dafeng Père David's Deer National Nature Reserve between July 2010 and July 2011. Bacteria isolated using blood agar and mannitol agar plates were identified by Gram staining and nested PCR for 16S rRNA. We isolated C. perfringens from 41 fecal samples and used PCR amplification of five toxin genes to identify the toxinotypes and the cpe(+) strains of C. perfringens. Twenty-one isolates were type A, 15 were type E, and five were type D. Fifteen isolates were cpe(+) strains, including eight that were type A and seven that were type E. PMID:25050802

Characterization Report for the David Witherspoon Screen Art Site  

Energy Technology Data Exchange (ETDEWEB)

The U.S. Department of Energy (DOE) Oak Ridge Office (ORO) of Environmental Management (EM) requested the technical assistance of Oak Ridge Institute for Science and Education (ORISE) to characterize a tract of land associated with the David Witherspoon, Incorporated (DWI) Volunteer Equipment and Supply Company (VESC). This tract of land (hereinafter referred to as Screen Arts) is located in the Vestal Community in the 2000-block of Maryville Pike in south Knoxville, Tennessee, as shown in Figure A-1. This tract of land has been used primarily to store salvaged equipment and materials for resale, recycle, or for disposal in the former landfill once operated by DWI. The DWI Site industrial landfill and metal recycling business had been permitted by the Tennessee Division of Radiological Health to accept low-level radiologically contaminated metals. DWI received materials and equipment associated with operations from DOE sites, including those in Oak Ridge, Tennessee; Paducah, Kentucky; and Portsmouth, Ohio. It is likely that items stored at Screen Arts may have contained some residual radiological materials.

Space craft verification at the David Florida Laboratory  

Science.gov (United States)

The David Florida Laboratory offers facilities and staff to support the integration and environmental testing of space subsystems and complete spacecraft. These capabilities encompass thermal verification and dynamic testing (vibration and modal analysis), as well as radio frequency (antenna pattern, RFI/EMC) measurements. Clean rooms are provided for the integration of solar arrays, antennas and spacecraft, and a range of ancillary support services facilitates the measurement of materials and mass properties and outgassing. These facilities, recently deployed in support of the Olympus program, are currently being exercised for the Anik-E satellites. Upgradings driven by the Olympus program encompass the thermal and dynamic domains and include an accurate, high capacity temperature measurement system and an additional support structure permitting vibration testing of very large and dynamically responsive test articles. Anik-E placed additional demands on laboratory capabilities but these upgradings are expected to be overshadowed by the test technology developments which may be mandatory to satisfy the requirements of MSAT, Radarsat and Space Station programs. These improvements could include an extended antenna measurement capability, improved deployment suspensions for large lightweight structures, materials testing for long duration, low earth orbit exposure and static load testing. Furthermore, the current trends toward enhanced capabilities are finding applications in a number of related disciplines such as radar.

David Florida Laboratory: Support for mobile satellite communications  

Science.gov (United States)

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.

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.)

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)

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.

David Maurice's contributions to optical ophthalmic instrumentation: roots of the scanning slit clinical confocal microscope.  

Science.gov (United States)

This paper explores the seminal contributions of David Maurice to the field of ophthalmic instrumentation. His development of the specular microscope, the scanning slit optical confocal microscope, and the corneal microfluorometer resulted in advances in our understanding of corneal morphology, physiology, and pathology. The development of the scanning slit, clinical confocal microscope is not a new paradigm or a paradigm shift, but a continuous series of interlinked technical advances from the early work of Vogt to Thaer's development of a clinical confocal microscope. For each instrument both the connection to the prior work of others and the unique advances are discussed and contrasted. This paper develops the connections and parallel developments in the instrument developments of Goldmann, Maurice, Svishchev, Baer, Koester, Masters, and Thaer. The evidence in support of the thesis consists of published papers, patents, personal communication, and study of Goldmann's book collection in Bern. A second theme is that knowledge of physics is a prerequisite for optical instrument development in ophthalmology. David Maurice had a university degree in physics and Hans Goldmann learned physics from his books. The contributions of David Maurice to optical instrumentation follow the major contributions of Goldmann and facilitated and stimulated other scientists who acknowledged their important intellectual debt to David Maurice.

MOND theory  

CERN Document Server

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...

The post-perspectival: screens and time in David Lynch's Inland Empire  

Directory of Open Access Journals (Sweden)

Full Text Available 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 with reference to a new media genre like the website with its hyperlink structure. Finally, the article discusses how a sense of ubiquitous surveillance coalesces with the screen logic.Author Biography Anne Jerslev (PhD is Professor of Film and Media Studies at the Department of Media, Cognition and Communication, University of Copenhagen.

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

Directory of Open Access Journals (Sweden)

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

Uncertainty theory  

CERN Document Server

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...

Agency Theory  

DEFF Research Database (Denmark)

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.

Finite hedging in field theory models of interest rates.  

Science.gov (United States)

We use path integrals to calculate hedge parameters and efficacy of hedging in a quantum field theory generalization of the Heath, Jarrow, and Morton [Robert Jarrow, David Heath, and Andrew Morton, Econometrica 60, 77 (1992)] term structure model, which parsimoniously describes the evolution of imperfectly correlated forward rates. We calculate, within the model specification, the effectiveness of hedging over finite periods of time, and obtain the limiting case of instantaneous hedging. We use empirical estimates for the parameters of the model to show that a low-dimensional hedge portfolio is quite effective. PMID:15089384

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 eshoenberg 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.

The Role of Naturalness in Lewis's Theory of Meaning  

Directory of Open Access Journals (Sweden)

Full Text Available Many writers have held that in his later work, David Lewis adopted a theory of predicate meaning such that the meaning of a predicate is the most natural property that is (mostly consistent with the way the predicate is used. That orthodox interpretation is shared by both supporters and critics of Lewis's theory of meaning, but it has recently been strongly criticised by Wolfgang Schwarz. In this paper, I accept many of Schwarze's criticisms of the orthodox interpretation, and add some more. But I also argue that the orthodox interpretation has a grain of truth in it, and seeing that helps us appreciate the strength of Lewis's late theory of meaning.

Bohmian Mechanics The Physics and Mathematics of Quantum Theory  

CERN Document Server

Bohmian Mechanics was formulated in 1952 by David Bohm as a complete theory of quantum phenomena based on a particle picture. It was promoted some decades later by John S. Bell, who, intrigued by the manifestly nonlocal structure of the theory, was led to his famous Bell's inequalities. Experimental tests of the inequalities verified that nature is indeed nonlocal. Bohmian mechanics has since then prospered as the straightforward completion of quantum mechanics. This book provides a systematic introduction to Bohmian mechanics and to the mathematical abstractions of quantum mechanics, which range from the self-adjointness of the Schrödinger operator to scattering theory. It explains how the quantum formalism emerges when Boltzmann's ideas about statistical mechanics are applied to Bohmian mechanics. The book is self-contained, mathematically rigorous and an ideal starting point for a fundamental approach to quantum mechanics. It will appeal to students and newcomers to the field, as well as to established sc...

Records Theory  

CERN Document Server

In quantum gravity, one seeks to combine quantum mechanics and general relativity. In attempting to do so, one comes across the `problem of time' impasse: the notion of time is conceptually different in each of these theories. In this seminar, I consider the timeless records approach toward resolving this. Records are localized, information-containing subconfigurations of a single instant. Records theory is the study of these and of how science (or history) is to be abstracted from correlations between them. I critically evaluate motivations for this approach that have previously appeared in the literature. I provide a ground-level structure for records theory and discuss what kind of further tools are needed, illustrated with some toy models: ordinary mechanics, relatonal particle dynamics, detector models and inhomgeneous perturbations about homogeneous cosmology.

Scattering theory  

Energy Technology Data Exchange (ETDEWEB)

Written by the author of the widely acclaimed textbook. Theoretical Atomic Physics Includes sections on quantum reflection, tunable Feshbach resonances and Efimov states. Useful for advanced students and researchers. This book presents a concise and modern coverage of scattering theory. 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. 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. The level of abstraction is kept as low as at all possible, and deeper questions related to mathematical foundations of scattering theory are passed by. The book should be understandable for anyone with a basic knowledge of nonrelativistic quantum mechanics. It is intended for advanced students and researchers, and it is hoped that it will be useful for theorists and experimentalists alike.

Theory summary  

International Nuclear Information System (INIS)

This is a summary of the advances in magnetic fusion energy theory research presented at the 17th International Atomic Energy Agency Fusion Energy Conference from 19 24 October, 1998 in Yokohama, Japan. Theory and simulation results from this conference provided encouraging evidence of significant progress in understanding the physics of thermonuclear plasmas. Indeed, the grand challenge for this field is to acquire the basic understanding that can readily enable the innovations which would make fusion energy practical. In this sense, research in fusion energy is increasingly able to be categorized as fitting well the 'Pasteur's Quadrant' paradigm, where the research strongly couples basic science ('Bohr's Quadrant') to technological impact ('Edison's Quadrant'). As supported by some of the work presented at this conference, this trend will be further enhanced by advanced simulations. Eventually, realistic three-dimensional modeling capabilities, when properly combined with rapid and complete data interpretation of results from both experiments and simulations, can contribute to a greatly enhanced cycle of understanding and innovation. Plasma science theory and simulation have provided reliable foundations for this improved modeling capability, and the exciting advances in high-performance computational resources have further accelerated progress. There were 68 papers presented at this conference in the area of magnetic fusion energy theory

For some, it simply comes down to strings. This September 2, 2003 New York Times article does a good job of summarizing the history and specifics of string theory and the paradox of its many offerings (1). One-time egistration is required to access any New York Times articles. The next site is the homepage of the Kavli Institute for Theoretical Physics at the University of California Santa Barbara and home to some of the most intense thinking with regards to theoretical physics in the world (2). Going from highly technical to more popularly palatable, NOVA offers the third site (3 ). Called, The Elegant Universe, the upcoming NOVA special is based on Columbia University professor Brian Greene's highly acclaimed book of the same title. As the site states, "Eleven dimensions, parallel universes, and a world made out of strings. It's not science fiction, it's string theory." The next site takes you directly to the virtual home of string theory (4 ). Here you will find the basics on the topic as well as what scientists have found so far and where they're headed next. Probably the most definitive site devoted to the topic. The fifth site is another informative look at superstring theory and is provided by John Pierre at MIT. While a very basic Web site, in terms of design, it offers a great tutorial on strings in addition to a glossary and reference list (5 ). The final link (6 ) will take you "Beyond Einstein, from the Big Bang to Black Holes." The site, provided by NASA, offers insights into the history and structure of the universe.

Urban common space, heterotopia and the right to the city: reflections on the ideas of Henri Lefebvre and David Harvey / Espaço urbano comum, heterotopia e o direito à cidade: reflexões a partir do pensamento de Henri Lefebvre e David Harvey  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese Os espaços urbanos comuns da cidade são apropriados pelo capital visando garantir as condições necessárias para a produção-reprodução das relações capitalistas. 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.

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

Science.gov (United States)

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.

Transport theory  

International Nuclear Information System (INIS)

The various quantities used in the theory are defined; starting from fundamental property of neutron transport, the integro-differential form of the transport equation is established with its associated boundary conditions, and then the integral form. The second part is devoted to the fundamental theorems of the theory; to begin with, the reciprocity theorem is considered; a number of examples is also given illustrating the facility with which it can be applied to practical cases; finally the complementarity theorem is dealt with; from this theorem one then derives naturally a third, less known, form of the transport equation; from this version of the equation a very rapidly converging analytical method of solution is obtained; it has been the subject of several researches during the last few years

Gauge theories  

International Nuclear Information System (INIS)

An introduction to the unified gauge theories of weak and electromagnetic interactions is given. The ingredients of gauge theories and symmetries and conservation laws lead to discussion of local gauge invariance and QED, followed by weak interactions and quantum flavor dynamics. The construction of the standard SU(2)xU(1) model precedes discussion of the unification of weak and electromagnetic interactions and weak neutral current couplings in this model. Presentation of spontaneous symmetry breaking and spontaneous breaking of a local symmetry leads to a spontaneous breaking scheme for the standard SU(2)xU(1) model. Consideration of quarks, leptons, masses and the Cabibbo angles, of the four quark and six quark models and CP violation lead finally to grand unification, followed by discussion of mixing angles in the Georgi-Glashow model, the Higgses of the SU(5) model and proton/ neutron decay in SU(5).

Potential theory  

CERN Document Server

Potential Theory presents a clear path from calculus to classical potential theory and beyond, with the aim of moving the reader into the area of mathematical research as quickly as possible. The subject matter is developed from first principles using only calculus. Commencing with the inverse square law for gravitational and electromagnetic forces and the divergence theorem, the author develops methods for constructing solutions of Laplace's equation on a region with prescribed values on the boundary of the region. The latter half of the book addresses more advanced material aimed at those with the background of a senior undergraduate or beginning graduate course in real analysis. Starting with solutions of the Dirichlet problem subject to mixed boundary conditions on the simplest of regions, methods of morphing such solutions onto solutions of Poisson's equation on more general regions are developed using diffeomorphisms and the Perron-Wiener-Brelot method, culminating in application to Brownian motion.

The harm of male-on-female rape: a response to David Benatar.

This article attacks David Benatar's claim made in his 2012 book, The Second Sexism: Discrimination Against Men and Boys, that when an individual is the victim of violence it does not matter whether his or her perpetrator is of the same or a different sex. By exploring two related yet distinct phenomena, well documented in the empirical psychological literature, that I call "shattering" and "fragmentation," I argue that when a woman is raped, it does matter that her rapist is male, given that her situation as a woman under patriarchy is partly constitutive of the harm that she suffers.

Analyses using marker information revealed evidence for a QTL for date at pedicle initiation (LOD = 3.7) and live weight at pedicle initiation (LOD = 3.1). These QTL explained 13% and 11% of the phenotypic variance in these traits, respectively. PMID:10994707

Here I counter his criticisms--firstly, by clarifying the terminology: What counts as a lie? Secondly, by exploring further what makes lying wrong. Bakhurst maintains that lying is wrong in that it infringes autonomy--and other deceiving stratagems, he says, do so equally. I maintain that lying is wrong in that it endangers trust--and other types of de...

Gyrotron theory  

International Nuclear Information System (INIS)

The gyrotron or electron-cyclotron-resonance-maser is a high-power microwave source in which the microwave field gains energy from a beam of relativistic electrons. At present time, the development is being stimulated by the demand for high-power microwave radiation to heat tokamak plasmas to fusion temperatures and by new radar applications. The heart of the device is a resonant cavity in a steady magnetic field. A hallow cylindrical beam of electrons gyrating about the magnetic field direction with relativistic energies enters the cavity and interacts with the microwave there. The microwave field gain energy from the electrons and a fraction of this energy leaves the cavity via the output waveguide. In this work, some general properties of relativistic coherent states of electrons moving in a steady and homo-geneous magnetic are presented and three types of eigenfunctions as solutions of the Klein-Gordon-Equation are considered. These eigenstates are multipletts. The multipletts are constructed as eigenstates of Johnson-Lippmann-Operators and the influence of the microwave field is investigated by perturbation theory. The resulting stability problem for perturbation theory is solved and the Floquet-Exponent is calculated to second order. By coupling the Klein-Gordon current with the wavefunction of photons, selections rules for the Redmond-Field can be derived. The expection values of light-emission are determined by using Fermis Golden Rule. Asup>Fermis Golden Rule. A further purpose of this article is to show, that quantum theory is needed to derive correct results. (author)

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.

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.

Bosquejos de niñez y proyectos de vida en la novela de Dickens “David Copperfield”  

Directory of Open Access Journals (Sweden)

Full Text Available La interpretación de la novela de Charles Dickens David Copperfield se propone destacar las formas en que la literatura somete a debate bosquejos de subjetividad e interacción. El interés central es la asignación cultural de atributos individuales que derivan de esquemas predeterminados sobre valores personales y de formas de vida. A la construcción social del prejuicio se le brinda especial atención. El hilo del análisis lo lleva la interacción entre la figuras narrativas de David Copperfield y Urias Heep, pues conforman antípodas reflejo de antagonismos sociales. La configuración de contrastes entre las características de los personajes –los proyectos que encarnan y sus destinos– ofrece un campo para el estudio de las orientaciones para la acción en la vida cotidiana. Tal configuración prevé ordenamientos de la experiencia. Se hace énfasis en los elementos fundadores de una jerarquía de estilos y mundos de vida, que a su vez muestran cómo diferentes niveles simbólicos están comprometidos en la asignación de roles sociales y sus significados para un colectivo.

Recovery of handwritten text from the diaries and papers of David Livingstone  

Science.gov (United States)

During his explorations of Africa, David Livingstone kept a diary and wrote letters about his experiences. Near the end of his travels, he ran out of paper and ink and began recording his thoughts on leftover newspaper with ink made from local seeds. These writings suffer from fading, from interference with the printed text and from bleed through of the handwriting on the other side of the paper, making them hard to read. New image processing techniques have been developed to deal with these papers to make Livingstone's handwriting available to the scholars to read. A scan of the David Livingstone's papers was made using a twelve-wavelength, multispectral imaging system. The wavelengths ranged from the ultraviolet to the near infrared. In these wavelengths, the three different types of writing behave differently, making them distinguishable from each other. So far, three methods have been used to recover Livingstone's handwriting. These include pseudocolor (to make the different writings distinguishable), spectral band ratios (to remove text that does not change), and principal components analysis (to separate the different writings). In initial trials, these techniques have been able to lift handwriting off printed text and have suppressed handwriting that has bled through from the other side of the paper.

Has David Howden Vindicated Richard von Mises’s Definition of Probability?  

Directory of Open Access Journals (Sweden)

Full Text Available In my recent article on these pages (Crovelli 2009 I argued that members of the Austrian School of economics have adopted and defended a faulty definition of probability. I argued that the definition of probability necessarily depends upon the nature of the world in which we live. I claimed that if the nature of the world is such that every event and phenomenon which occurs has a cause of some sort, then probability must be defined subjectively; that is, “as a measure of our uncertainty about the likelihood of occurrence of some event or phenomenon, based upon evidence that need not derive solely from past frequencies of ‘collectives’ or ‘classes.’” I further claimed that the nature of the world is indeed such that all events and phenomena have prior causes, and that this fact compels us to adopt a subjective definition of probability.David Howden has recently published what he claims is a refutation of my argument in his article “Single Trial Probability Applications: Can Subjectivity Evade Frequency Limitations” (Howden 2009. Unfortunately, Mr. Howden appears to not have understood my argument, and his purported refutation of my subjective definition consequently amounts to nothing more than a concatenation of confused and fallacious ideas that are completely irrelevant to my argument. David Howden has thus failed in his attempt to vindicate Richard von Mises’s definition of probability.

Effect of total dissolved gas supersaturated water on early life of David's schizothoracin (Schizothorax davidi).  

Science.gov (United States)

The effect of total dissolved gas (TDG) supersaturation on fish living downstream of dams is one of the main ecological risks of high dam construction. A strategy for mitigating the negative effects is needed urgently since many high dams are under construction in the upper reaches of the Yangtze River in China. Experiments on the hatching process of David's schizothoracin were carried out and the results show that the hatching rate decreased with increasing TDG levels, and that most eggs hatched within a very short time in the higher TDG saturation groups. By using a stereomicroscope, damages to the head, yolk sac, body, anus, etc. were found in larvae which hatched in TDG supersaturated water. Results show that the lesion rate increased with increasing TDG levels. Furthermore, 7-d-old David's schizothoracin were exposed to TDG supersaturated water levels of 100%, 105%, 110%, 115%, 120%, 125%, 130%, 135%, and 140% for testing their tolerance to TDG supersaturation. We found that the median lethal concentrations (LC50) for 13, 14, 20, 35, 52, 73, and 96 h exposure were 138%, 138%, 134%, 130%, 129%, 128%, and 126%, respectively. The median lethal times (LT50) were 7.49, 11.04, 19.25, and 35.38 h for exposure to water with TDG levels of 145%, 140%, 135%, and 130%, respectively. PMID:23825149

The David and Goliath principle: cultural, ideological, and attitudinal underpinnings of the normative protection of low-status groups from criticism.  

Science.gov (United States)

Two studies documented the "David and Goliath" rule--the tendency for people to perceive criticism of "David" groups (groups with low power and status) as less normatively permissible than criticism of "Goliath" groups (groups with high power and status). The authors confirmed the existence of the David and Goliath rule across Western and Chinese cultures (Study 1). However, the rule was endorsed more strongly in Western than in Chinese cultures, an effect mediated by cultural differences in power distance. Study 2 identified the psychological underpinnings of this rule in an Australian sample. Lower social dominance orientation (SDO) was associated with greater endorsement of the rule, an effect mediated through the differential attribution of stereotypes. Specifically, those low in SDO were more likely to attribute traits of warmth and incompetence to David versus Goliath groups, a pattern of stereotypes that was related to the protection of David groups from criticism.

Options theory  

International Nuclear Information System (INIS)

Techniques used in conventional project appraisal are mathematically very simple in comparison to those used in reservoir modelling, and in the geosciences. Clearly it would be possible to value assets in mathematically more sophisticated ways if it were meaningful and worthwhile so to do. The DCf approach in common use has recognized limitations; the inability to select a meaningful discount rate being particularly significant. Financial Theory has advanced enormously over the last few years, along with computational techniques, and methods are beginning to appear which may change the way we do project evaluations in practice. The starting point for all of this was a paper by Black and Scholes, which asserts that almost all corporate liabilities can be viewed as options of varying degrees of complexity. Although the financial presentation may be unfamiliar to engineers and geoscientists, some of the concepts used will not be. This paper outlines, in plain English, the basis of option pricing theory for assessing the market value of a project. it also attempts to assess the future role of this type of approach in practical Petroleum Exploration and Engineering economics. Reference is made to relevant published Natural Resource literature

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)

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.

W???????? ??? : A propos du roman inédit de David Vogel en yiddish “W ??? ???????” : About David Vogel’s unpublished novel in Yiddish ??????? ??? W : ????? ??? ???????? ????–??????????????? ??????? ???????  

Directory of Open Access Journals (Sweden)

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?? ????? ???? ??? ?????????? ??????? ??? ???????

Number Theories  

CERN Document Server

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.

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

Animals and nature: mapping storylines and metaphors in David Kramer’s narratives  

Directory of Open Access Journals (Sweden)

Full Text Available This article discusses the representation of animals and nature in selected lyrics from the oeuvre of singer, songwriter and producer David Kramer and considers his engagement with historical and contemporary discourses about human-animal and human-nature interaction in relation to ecological awareness within a South African context. I trace the socio-political commentary voiced through his depiction of animals in the folksongs he wrote during apartheid, especially in lyrics from the album “Baboondogs” (Kramer, 1986. Kramer also employs intertextual references to traditional South African folksongs and tales in his music. Furthermore, the social and environmental significance of Kramer’s representations of nature in a selection of his postapartheid lyrics is investigated. I argue that the pedagogical value of Kramer’s cultural commentary can contribute significantly to the challenge of teaching animal studies and ecocriticism in South African context.

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

Directory of Open Access Journals (Sweden)

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.

The Dehumanizing American Dream in David Mamet’s Glengarry Glen Ross  

Directory of Open Access Journals (Sweden)

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 the human spirit. It is also shown, through the analysis of David Mamet’s glengarry Glen Ross, that despite the promise of the dream it contains many contradictions. 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, for instance, as  the most prominent of these ideologies, disrupts all communal bonds and even exceeds to the disintegration of friendship and family life.

A Map Worth Glancing At : A Conversation on Utopias with David Pinder  

DEFF Research Database (Denmark)

“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

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.

Pobreza global o desigualdad doméstica: Una crítica a las propuestas de David Miller y Laura Valentini

Full Text Available SciELO Colombia | Language: Spanish Abstract in spanish En este trabajo cuestiono las razones que ofrecen David Miller y Laura Valentini para afirmar que el deber de reducir la desigualdad dentro del propio Estado tiene prioridad sobre el deber de reducir la pobreza extrema global. Según Miller, los deberes globales, a diferencia de los domésticos, no pu [...] eden legítimamente hacerse cumplir mediante la fuerza, y por esa razón son meros deberes humanitarios que tienen menor peso que los deberes domésticos, que son deberes de justicia. Según Valentini, el deber de reducir la desigualdad doméstica tiene prioridad sobre los deberes humanitarios globales porque el primero es un deber de no dañar, mientras que los segundos son meros deberes de ayudar. El problema principal de ambas propuestas consiste en que fallan en su intento de mostrar que los deberes de reducir la pobreza extrema global no son también deberes de justicia. Abstract in english In this article I question David Miller and Laura Valentini's reasons to claim that duties to reduce inequalities inside the State should be prioritized over duties to reduce extreme global poverty. According to Miller, global duties, unlike domestic ones, cannot be legitimately enforced, and they a [...] re therefore mere humanitarian duties that weigh less than domestic duties, which are duties of justice. According to Valentini, domestic duties should be prioritized over global humanitarian duties because the former are duties not to harm, while the latter are mere duties to help. I argue that both views fail in their attempt to show that duties to reduce extreme global poverty are not duties ofjustice too.

Imperi coloniali da Oriente a Occidente: immagini dell’Altro da Tacito a David Malouf, da Salman Rushdie a Michael Ondaatje  

Directory of Open Access Journals (Sweden)

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.

Response to the Point of View of Gregory B. Pauly, David M. Hillis, and David C. Cannatella, by the Anuran Subcommittee of the SSAR/HL/ASIH Scientific and Standard English Names List  

Science.gov (United States)

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.

The foundation consists of (1) a glossary of fundamental concepts; (2) a theorem that delineates the overlap between Lagrangian-based theories and metric theories; (3) a conjecture (due to Schiff) that the Weak Equivalence Principle implies the Einstein Equivalence Principle; and (4) a plausibility argument supporting this conjecture for the special case of relativistic, Lagrangian-based theories.

Jane Eyre de Michael Berkeley et de David Malouf : La transposition opératique d’un grand classique de la littérature anglaise Jane Eyre by Michael Berkeley and David Malouf: The Operatic Rewriting of a Great Classic English Novel  

Directory of Open Access Journals (Sweden)

Full Text Available This article discusses Michael Berkeley’s opera Jane Eyre. Premiered on June 30, 2000 by Music Theatre Wales at the Cheltenham International Festival of Music, this opera is based on the novel by Charlotte Brontë and the libretto is written by the Australian poet, novelist, playwright and librettist, David Malouf. It was risky and daring to try to adapt this famous and long novel for the stage. We will particularly focus on the similarities and differences between the novel and the opera as well as on the strategies used both by David Malouf and Michael Berkeley to adapt it. Through the analysis of the similarities we will see how Michael Berkeley set to music some of the great themes and elements of the novel: passion, a sense of entrapment, the “Gothic” atmosphere. On the other hand, the analysis of the discrepancies between the novel and the opera as they appear in both the libretto and the music will lead us to a modern apprehension of the characterization of madness as well as of the metafictional dimension of the rewriting of Jane Eyre by David Malouf and Michael Berkeley.

Bohmian mechanics. The physics and mathematics of quantum theory  

Energy Technology Data Exchange (ETDEWEB)

Bohmian Mechanics was formulated in 1952 by David Bohm as a complete theory of quantum phenomena based on a particle picture. It was promoted some decades later by John S. Bell, who, intrigued by the manifestly nonlocal structure of the theory, was led to his famous Bell's inequalities. Experimental tests of the inequalities verified that nature is indeed nonlocal. Bohmian mechanics has since then prospered as the straightforward completion of quantum mechanics. This book provides a systematic introduction to Bohmian mechanics and to the mathematical abstractions of quantum mechanics, which range from the self-adjointness of the Schroedinger operator to scattering theory. It explains how the quantum formalism emerges when Boltzmann's ideas about statistical mechanics are applied to Bohmian mechanics. The book is self-contained, mathematically rigorous and an ideal starting point for a fundamental approach to quantum mechanics. It will appeal to students and newcomers to the field, as well as to established scientists seeking a clear exposition of the theory. (orig.)

We suggest that in the early stages of an industry's sustainability transformation, new entrants (‘Emerging Davids’) are more likely than incumbents to pursue sustainability-related opportunities. Incumbents react to the activities of new entrants by engaging in corporate sustainable entrepreneurship activities. While these ‘Greening Goliaths’ are often less ambitious in their e...

EXTENDING JUST WAR THEORY: THE JUS AD BELLUM AND THE CAPABILITIES APPROACH TO ARMED CONFLICT  

Directory of Open Access Journals (Sweden)

Full Text Available As the nature of armed conflict continues to change, so the living ethical traditionthat is just war theory has to adapt to meet new challenges. This paper offers aproposal for extending just war theory by incorporating into its framework a humancapabilities-based ethic drawn from the work of Martha Nussbaum. This newapproach is analysed in the light of two important recent challenges to just wartheory: David Rodin’s critique of the principle of national defence, and the emergingdoctrine of humanitarian intervention. While the results of this analysis can only beconsidered to be preliminary, the authors argue that indications are thatsupplementing just war theory with Nussbaum’s human capabilities-based ethic, orsomething similar, could yield significant benefits for the ethical analysis ofcontemporary armed conflicts.

Language as a source of evidence for theories of spatial representation.  

Science.gov (United States)

David Marr's metatheory emphasized the importance of what he called the computational level of description--an analysis of the task the visual system performs. In the present article I argue that this task should be conceived of not just as object recognition but as spatial understanding, and that the mental representations responsible for spatial understanding are not exclusively visual in nature. In particular, a theory of the visual system must interact with a theory of the language faculty to explain how we talk about what we see--and how we see all the things we talk about as though they are part of the perceived world. An examination of spatial language both raises the bar for theories of vision and provides important hints for how spatial understanding is structured. PMID:23409376

The discourse of two individuals participating in an environmentalist assembly is analyzed on the speech acts level with the David Liberman algorithm (DLA). The purpose of analyzing two actors in the same assembly allows to contrast the rhetoric expressed in their appeals. According to the results, person A's predominant use of the language of power manifests a vengeful and righteous ideal supported by language expressed in narrative, orderly fashion evoking empathic understanding. His final argument is an appeal against the government authority, considered antagonistic, and in favor of an organization based on natural regulation, implying total equality and no hierarchies. On the other hand, person B uses the language that predominantly implies duty and order, targeting an ambitious ideal with plans to access his rivals in order to govern. Finally, the article assesses the scope of these arguments, its similarities and differences. To conclude, the contributions of this study and foresight are precised.

The international coal industry: comments on the paper by David Humphreys and Keith Welham  

International Nuclear Information System (INIS)

This comment discusses in more detail one of the primary messages in the paper by David Humphreys and Keith Welham, namely the fundamental shift in the steam coal industry away from security of supply concerns and national focuses towards an international and cost-driven perspective. On the supply side this has meant an increased focus on mining productivity. By consulting recent research this comment reviews the sources of productivity growth in the coal industry and discusses the prospects for future improvements. The demand side of the steam coal market has also witnessed fundamental change as electric utilities have become more cost focused. In the 1970s and early 1980s nuclear was the main competitor to coal, but today the fiercest competition comes from gas. While coal benefits from the favourable economics of existing plants, gas use tends to be cheaper on a total cost basis and it is also environmentally more benign. The competition from gas therefore puts new and different competitive pressures on steam coal. Not only does coal procurement need to become more flexible and diverse; the negative perception of coal as a dirty fuel has to weaken as well. (orig.)

Protease inhibitors and beyond: interview with David Feigal, M.D. Interview by John S James.  

Science.gov (United States)

Dr. David Feigal, M.D., Director of the Division of Antiviral Drug Products of the U.S. Food and Drug Administration (FDA), agrees that protease inhibitors are the most promising single approach to HIV treatment today. There are, however, several obstacles to the development of these experimental drugs. The compounds are difficult to produce, often requiring multi-step synthesis processes, and there are additional problems with trying to scale-up to large quantities. The supply problem makes it difficult to decide how to provide the product to people who cannot participate in clinical trials. The lottery method, used with Betaseron for multiple sclerosis, was unpopular. Dr. Feigal suggests a partnership between the community and the companies to devise a distribution strategy. In addition, there are other treatment options showing preliminary data results in the same general magnitude as the protease inhibitors. Dr. Feigal also mentions that a workshop on AIDS clinical trials will be organized for late spring or early summer. PMID:11362331

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

Directory of Open Access Journals (Sweden)

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.

Extended Theories of Gravitation

Extended theories of gravitation are naturally singled out by an analysis inspired by the Ehelers-Pirani-Schild framework. In this framework the structure of spacetime is described by a Weyl geometry which is enforced by dynamics. Standard General Relativity is just one possible theory within the class of extended theories of gravitation. Also all Palatini f(R) theories are shown to be extended theories of gravitation. This more general setting allows a more general interpretation scheme and ...

Gauge theory loop operators and Liouville theory  

International Nuclear Information System (INIS)

We propose a correspondence between loop operators in a family of four dimensional N=2 gauge theories on S4 - 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 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 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.

Obliczeniowe teorie ?wiadomo?ci (Computational theories of consciousness  

Directory of Open Access Journals (Sweden)

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.

Asymptotic freedom in the theory of the strong interaction. Comment on the nobel prize in physics 2004  

International Nuclear Information System (INIS)

The 2004 Nobel Prize in Physics was awarded to David J. Gross, Frank Wilczek and H. David Politzer for their decisive contributions to the theory of the asymptotic freedom of the strong interaction (a fundamental interaction). The fundamental elements of quantum chromodynamics (QCD) and the theory of the strong interaction are briefly reviewed in their historical context. How to achieve asymptotic freedom is introduced and its physical meaning explained. The latest experimental tests of asymptotic freedom are presented, and it is shown that the theoretical prediction agrees excellently with the experimental measurements. Perturbative QCD which is based on the asymptotic freedom is outlined. It is pointed out that the theoretical discovery and experimental proof of the asymptotic freedom are crucial for QCD to be the correct theory of strong interaction. Certain frontier research areas of QCD, such as 'color confinement', are mentioned. The discovery and confirmation of asymptotic freedom has indeed deeply affected particle physics, and has led to QCD becoming a main content of the standard model, and to further development of the so-called grand unification theories of interactions.

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)

Molecular theory of graphene  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Odd electrons of benzenoid units and correlation of these electrons having different spins are the main concepts of the molecular theory of graphene. In contrast to the theory of aromaticity, the molecular theory is based on the fact that odd electrons with different spins occupy different places in the space so that the configuration interaction becomes the central point of the theory. Consequently, a multi-determinant presentation of the wave function of the system of weak...

Constructivist Grounded Theory?

Full Text Available AbstractI refer to and use as scholarly inspiration Charmaz’s excellent article on constructivist grounded theory as a tool of getting to the fundamental issues on why grounded theory is not constructivist.

Tubular Field Theory  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We propose tubular field theory, which is a continuum analogue of lattice field theory. One-dimensional links (and zero-dimensional sites) in lattice field theory are replaced by two-dimensional tubes to result in two-dimensional spacetime microscopically. As an example, scalar and gauge fields are considered in `three-dimensional' tubular spacetime.

Full Text Available This article captures the key learning lessons gleaned from the author’s experience learning and developing a grounded theory for his doctoral dissertation using the classic methodology as conceived by Barney Glaser. The theory was developed through data gathered on founders and successors of Malaysian Chinese family-own businesses. The main concern for Malaysian Chinese family businesses emerged as dynasting . the building, maintaining, and growing the power and resources of the business within the family lineage. The core category emerged as dynasting across cultures, where founders and successors struggle to transition from traditional Chinese to hybrid cultural and modernized forms of family business from one generation to the next. The key learning lessons were categorized under five headings: (a sorting through different versions of grounded theory, (b educating and managing research stakeholders, (c embracing experiential learning, (d discovering the core category: grounded intuition, and (e recognizing limitations and possibilities.Keywords: grounded theory, learning, dynasting, family business, Chinese

International Nuclear Information System (INIS)

This paper describes the main ideas in superstring theories, including open conjectures and remarkable properties. Emphasis is on the geometrical and topological properties of the theories. Both the supersymmetric and non-supersymmetric theories are considered. String theories are similar to general relativity in many respects, and these connections are discussed. The authors consider a single non-interacting bosonic string and consider the relation of superstrings to observed low energy physics. In particular, gauge interactions are discussed, and the gauge group is found to be essentially and uniquely determined by the theory

f(R Theories  

Directory of Open Access Journals (Sweden)

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.

Algorithmic information theory  

CERN Document Server

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.

The theory is applicable to a diatomic gas which adsorbs dissociatively on a getter material which exhibits a time independent sticking coefficient. The theory includes the effects of surface reactions and bulk diffusion. Exact numerical solutions are presented for the particular cases of pumping and desorption. In addition, approximate analytical solutions are derived and used to illustrate the characteristics of the particular operational regimes. The theory is applied to the analysis of the pumping and desorption behavior of the Zr-Al alloy bulk getter. The predictions of the theory are in excellent agreement with the experimentally measured Zr-Al performance

Finite quantum field theories  

International Nuclear Information System (INIS)

We investigate the relation between finiteness of a four-dimensional quantum field theory and global supersymmetry. To this end we consider the most general quantum field theory and analyse the finiteness conditions resulting from the requirement of the absence of divergent contributions to the renormalizations of the parameters of the theory. In addition to the gauge bosons, both fermions and scalar bosons turn out to be a necessary ingredient in a non-trivial finite gauge theory. In all cases discussed, the supersymmetric theory restricted by two well-known constraints on the dimensionless couplings proves to be the unique solution of the finiteness conditions. (Author)

Extended Theories of Gravitation  

Directory of Open Access Journals (Sweden)

Full Text Available Extended theories of gravitation are naturally singled out by an analysis inspired by the Ehelers-Pirani-Schild framework. In this framework the structure of spacetime is described by a Weyl geometry which is enforced by dynamics. Standard General Relativity is just one possible theory within the class of extended theories of gravitation. Also all Palatini f(R theories are shown to be extended theories of gravitation. This more general setting allows a more general interpretation scheme and more general possible couplings between gravity and matter. The definitions and constructions of extended theories will be reviewed. A general interpretation scheme will be considered for extended theories and some examples will be considered.

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.)

"Implicate order" and the good life : applying David Bohm's ontology in the human world  

DEFF Research Database (Denmark)

In an attempt to formulate a coherent view of quantum reality, the theoretical physicist David Bohm has proposed a new concept of order to supplement the mechanistic Cartesian order of traditional physics. The "implicate" order is a subtler and deeper order that emphasizes "unbroken wholeness in flowing movement," in contrast to the coarser and more superficial, "explicate" Cartesian order of distinct phenomena. This dissertation attempts to develop a meaning for the idea of implicate order in the human world. First is offerend an account of some evolutionary episodes in terms of implicate and explicate order which draws on compatible work in cosmology, embryogenesis, visual perception, brain memory, decision making and phenomenology. Two important characteristics of the implicate order are then identified: in an implicate order, the whole is enfolded (or represented) in each of its parts; and all parts renders different perspectives of the whole. Using arguments from decision making, the study of "flow" in human consciousness, and a model of skill acquisition, it is suggested that these characteristics manifest themselves in the human world as the "unity experience" and the "diversity experience," respectively. The former is the experience that a given part of one's life reveals a larger wholeness or unity; the subject-object distinction is transcended and one becomes absorbed in the flow of whatever activity is pursued. The latter is a deep appreciation of the diversity of ways in which people may seek the unity experience. These experiences are proposed as general values: social and psychological conditions ought to be such that these experiences are enhanced in all people. A two-by-two matrix of these experiences demonstrates the danger of pursuing one to the exclusion of the other. The experience of unity without diversity turns into absolutism, the insistence that one's chosen activities or beliefs are the only right one. The experience of diversity without unity becomes relativism, the excessivetolerance of and indifference to other people's pursuits. The good life lies in the simultaneous realization of both, unity-in-diversity. Lastly, it is suggested that this so-called unity-diversity matrix may be used as a personal compass the meaning of which is negotiated and calibrated in a community of users.

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

CERN Document Server

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.

Preserving the soul of medicine and physicians: a talk with David Whyte. Interview by Richard L. Reece.  

Science.gov (United States)

Richard L. Reece, MD, interviewed David Whyte, a poet, consultant, and author of The Heart Aroused, on December 15, 1999, to discuss preserving the soul of physicians in corporate America. David describes the soul as "a measure of our belonging in the world. When there is little sense of belonging, there is very little sense of soul." In the workplace, he thinks about whether "people have a sense of belonging to the particular work or the organization." He talks about life in the upper world of the workplace and life in the dark subterranean caves where the soul lives. The soul is where people's true creativity and imagination resides ... and by inviting it into the workplace, organizations and employees can become more successful, innovative, and adaptable. In corporate settings, he uses poetry to bring an understanding of the process of change, helping clients to understand individual and organizational creativity to transform the workplace. The poetry can teach and touch those places that the corporate language cannot speak to. PMID:10847937

Gauge Theories of Gravitation  

CERN Document Server

During the last five decades, gravity, as one of the fundamental forces of nature, has been formulated as a gauge field theory of the Weyl-Cartan-Yang-Mills type. The resulting theory, the Poincar\\'e gauge theory of gravity, encompasses Einstein's gravitational theory as well as the teleparallel theory of gravity as subcases. In general, the spacetime structure is enriched by Cartan's torsion and the new theory can accommodate fermionic matter and its spin in a perfectly natural way. The present reprint volume contains articles from the most prominent proponents of the theory and is supplemented by detailed commentaries of the editors. This guided tour starts from special relativity and leads, in its first part, to general relativity and its gauge type extensions a la Weyl and Cartan. Subsequent stopping points are the theories of Yang-Mills and Utiyama and, as a particular vantage point, the theory of Sciama and Kibble. Later, the Poincar\\'e gauge theory and its generalizations are explored and specific topi...

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 rmalism 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 rel

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.

Going beyond perturbation theory: Parametric Perturbation Theory  

CERN Document Server

We devise a {\\sl non--perturbative} method, called {\\sl Parametric Perturbation Theory} (PPT), which is alternative to the ordinary perturbation theory. The method relies on a principle of simplicity for the observable solutions, which are constrained to be linear in a certain (unphysical) parameter. The perturbative expansion is carried out in this parameter and not in the physical coupling (as in ordinary perturbation theory). We provide a number of nontrivial examples, where our method is capable to resum the divergent perturbative series, {\\sl extract} the leading asymptotic (strong coupling) behavior and {\\sl predict} with high accuracy the coefficients of the perturbative series. In the case of a zero dimensional field theory we prove that PPT can be used to provide the imaginary part of the solution, when the problem is analytically continued to negative couplings. In the case of a $\\phi^4$ lattice model 1+1 and of elastic theory we have shown that the observables resummed with PPT display a branch poi...

We describe defects - dislocations and disclinations - in the framework of Riemann-Cartan geometry. Curvature and torsion tensors are interpreted as surface densities of Frank and Burgers vectors, respectively. We propose new expression for the free energy describing static distribution of defects. Equations of nonlinear elasticity theory are used to fix the coordinate system. The Lorentz gauge yields equations for the principal chiral SO(3)-field. In the absence of defects the geometric model reduces to the elasticity theory for the displacement vector field and to the principal chiral SO(3)-field model for the spin structure. The example of the wedge dislocation shows that the elasticity theory reproduces only the linear approximation of the geometric theory of defects. We show also that the equations of asymmetric elasticity theory for the Cosserat media are naturally embedded in the geometric theory of defects as the gauge conditions.

Quantum theory without reduction  

International Nuclear Information System (INIS)

Quantum theory offers a strange, and perhaps unique, case in the history of science. Although research into its roots has provided important results in recent years, the debate goes on. Some theorists argue that quantum theory is weakened by the inclusion of the so called 'reduction of the state vector' in its foundations. Quantum Theory without Reduction presents arguments in favour of quantum theory as a consistent and complete theory without this reduction, and which is capable of explaining all known features of the measurement problem. This collection of invited contributions defines and explores different aspects of this issue, bringing an old debate into a new perspective, and leading to a more satisfying consensus about quantum theory.

Class field theory from theory to practice  

CERN Document Server

Global class field theory is a major achievement of algebraic number theory, based on the functorial properties of the reciprocity map and the existence theorem. The author works out the consequences and the practical use of these results by giving detailed studies and illustrations of classical subjects (classes, idèles, ray class fields, symbols, reciprocity laws, Hasse's principles, the Grunwald-Wang theorem, Hilbert's towers,...). He also proves some new or less-known results (reflection theorem, structure of the abelian closure of a number field) and lays emphasis on the invariant (/cal T) p, of abelian p-ramification, which is related to important Galois cohomology properties and p-adic conjectures. This book, intermediary between the classical literature published in the sixties and the recent computational literature, gives much material in an elementary way, and is suitable for students, researchers, and all who are fascinated by this theory. In the corrected 2nd printing 2005, the author improves s...

Ideal Theory and Utopia  

Directory of Open Access Journals (Sweden)

Full Text Available John Rawls presents his work on social justice as Ideal Theory. By taking an idealized scenario, he is able to consider the compatibility of different concepts relating to social justice without being hampered by all the complexities of society and its actors; an approach to social theorizing that comes exceptionally close to designing Utopia. This paper examines the link between Rawlsian Ideal Theory and Utopia, and offers an amended definition of Ideal Theory with the concept of Utopia in mind.

Evolutionary game theory is a relatively young mathematical theory that aims to formalize in mathematical terms evolution models in biology. In recent years this paradigm has penetrated more and more into other areas such as the linguistics, economics and engineering.

The Tensor Theory Space  

CERN Document Server

The tensor track is a background-independent discretization of quantum gravity which includes a sum over all topologies. We discuss how to define a functional renormalization group flow and the Wetterich equation in the corresponding theory space. This space is different from the Einsteinian theory space of asymptotic safety. It includes all fixed-rank tensor-invariant interactions, hence generalizes matrix models and the (Moyal) non-commutative field theory space.

Euclidean quantum field theory  

International Nuclear Information System (INIS)

This talk deals mainly with two aspects of Euclidean quantum field theory, one related to the problem of mathematical construction, the other related to the problem of physical interpretation. For the problem of the construction, methods based on the deep analogy between Euclidean quantum field theory and classical statistical mechanics are emphasized. In particular the lattice approximation strategy and its applications are described. For the problem of physical interpretation the main ideas of a proposal, according to which the Euclidean field theory can be interpreted as a stochastic field theory in the physical Minkowski space-time, are sketched.

Portfolio Theory Forward Testing  

Directory of Open Access Journals (Sweden)

Full Text Available Portfolio Theory has during many decades been considered as the holy grail of investment despite the fact that very few empirical studies in the public domain have shown that portfolio theory outperforms a random equal weighted portfolio. We will in this paper empirically investigate how successful portfolio theory is when it comes to generating large positive returns with low return volatility. The dataset that is used consists of approximately 4000 US stocks. We find weak support that portfolio theory by itself would have generated any returns different than a random portfolio allocation. In general optimized historical cumulative returns are not the same as forward cumulative returns.

The paper on superstring theory was presented to the workshop on 'Supersymmetry and its applications', Cambridge, United Kingdom, 1985. The classification of supersymmetry theories in ten dimensions is reviewed, and some of the salient properties of the five superstring theories that appear to be consistent are described. The structure of the light-cone-gauge field theory of superstrings is reviewed along with comments about possible alternative approaches. Finally, two-dimensional action principles for superstrings and their quantization are also discussed. (U.K.)

In fact, it can be said to be one of the greatest achievements in the development of this field. Presented in two dimensions, this book is designed for students who already have a basic knowledge of quantum mechanics, field theory and general relativity. The main idea used throughout the book is that conformal symmetry causes both classical and quantum integrability. Instead of concentrating on the numerous applications of the theory, the author puts forward a discussion of the general

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

Proof theory an introduction  

CERN Document Server

Although this is an introductory text on proof theory, most of its contents is not found in a unified form elsewhere in the literature, except at a very advanced level. The heart of the book is the ordinal analysis of axiom systems, with particular emphasis on that of the impredicative theory of elementary inductive definitions on the natural numbers. The "constructive" consequences of ordinal analysis are sketched out in the epilogue. The book provides a self-contained treatment assuming no prior knowledge of proof theory and almost none of logic. The author has, moreover, endeavoured not to use the "cabal language" of proof theory, but only a language familiar to most readers.

Exact numerical solutions are presented for the particular cases of pumping and desorption. In addition, approximate analytical solutions are derived and used to illustrate the characteristics of the particular operational regimes. The theory is applied to the analysis of the pumping and desorption behavior of the Zr-Al alloy bulk getter. The predictions of the theory are in excellent agreement with the experimentally measured Zr-Al performance

Theory in Social Marketing

Moreover, the chapter outlines how social marketers might benefit from a social epistemological approach.

Any topological theory of knots and links should be based on simple ideas of intersection and linking. In this book, a general theory of link bordism in manifolds and universal constructions of linking numbers in oriented 3-manifolds are developed. In this way, classical concepts of link theory in the 3-spheres are generalized to a certain class of oriented 3-manifolds (submanifolds of rational homology 3-spheres). The techniques needed are described in the book but basic knowledge in topology and algebra is assumed. The book should be of interst to those working in topology, in particular knot theory and low-dimensional topology.

RCRA Summary Document for the David Witherspoon 1630 Site, Knoxville, Tennessee  

Energy Technology Data Exchange (ETDEWEB)

The 48-acre David Witherspoon, Inc. (DWI) 1630 Site operated as an unregulated industrial landfill and scrap yard. The Tennessee Division of Superfund (TDSF) closed the landfill in 1974. During the period of operation, the site received solid and liquid wastes from salvage and industrial operations. The site consists of five separate tracts of land including a small portion located across the Norfolk Southern Railroad track. The landfill occupies approximately 5 acres of the site, and roughly 20 acres of the 48 acres contains surface and buried debris associated with the DWI dismantling business operation. Beginning in 1968, the state of Tennessee licensed DWI to receive scrap metal at the DWI 1630 Site, contaminated with natural uranium and enriched uranium (235U) not exceeding 0.1 percent by weight (TDSF 1990). The U.S. Department of Energy (DOE) has agreed to undertake remedial actions at the DWI 1630 Site as specified under a Consent Order with the Tennessee Department of Environment and Conservation (TDEC) (Consent Order No. 90-3443, April 4, 1991), and as further delineated by a Memorandum of Understanding (MOU) between DOE and the State of Tennessee (MOU Regarding Implementation of Consent Orders, October 6, 1994). The soil and debris removal at the DWI 1630 Site is being performed by Bechtel Jacobs Company LLC (BJC) on behalf of the DOE. Remediation consists of removing contaminated soil and debris from the DWI 1630 site except for the landfill area and repairing the landfill cap. The DWI 1630 remediation waste that is being disposed at the Environmental Management Waste Management Facility (EMWMF) as defined as waste lot (WL) 146.1 and consists primarily of soils and soil like material, incidental debris and secondary waste generated from the excavation of debris and soil from the DWI 1630 site. The WL 146.1 includes soil, soil like material (e.g., shredded or chipped vegetation, ash), discrete debris items (e.g., equipment, drums, large scrap metal, cylinders, and cable) and populations of debris type items (e.g., piles of bricks, small scrap metal, roofing material, scaffolding, and shelving) that are located throughout the DWI 1630 site. The project also generates an additional small volume of secondary waste [e.g., personal protective equipment (PPE), and miscellaneous construction waste] that is bagged and included in bulk soil shipments to the EMWMF. The Waste Acceptance Criteria (WAC) for the EMWMF does not allow for material that does not meet the Resource Conservation and Recovery Act (RCRA) Land Disposal Restrictions (LDRs). The waste being excavated in certain areas of the DWI 1630 site contained soil that did not meet RCRA LDR criteria; therefore this waste had to be segregated for treatment or alternate disposal offsite. This document identifies the approach taken by the DWI 1630 project to further characterize the areas identified during the Phase II Remedial Investigation (RI) as potentially containing RCRA-characteristic waste. This document also describes the methodology used to determine excavation limits for areas determined to be RCRA waste, post excavation sampling, and the treatment and disposal of this material.

Ortado?u ?le Kar??la?ma: David Greig’in Damascus Oyunu  

Directory of Open Access Journals (Sweden)

Full Text Available David Greig, as a Scottish playwright, has made a significant contribution not only to Scottish drama but also to the Drama ofBritain in the twenty-first century. He is responsive to the key political, cultural and aesthetic concerns and movements of today’sworld in his dramatic work.This paper investigates the playwright’s experience of ‘the other’ in Damascus** (2006 – a play in which Greig explores thecomplexities of relations between the West and the Arab world. While the playwright seizes the mystery of ‘the other’ in theworld’s oldest inhabited city, Damascus becomes a mythical place rooted in a contemporary reality. Despite the fact that the playis mostly a comedy of cultural confusion, it explores relationships between illusion and truth, fiction and fact. Through itsWestern and Arabic characters, the play analyzes preconceptions and stereotypes that Western and Mid-Eastern people have foreach other. In that sense, the play, for the most part, proposes a challenge to customary Western perceptions of the Mid-Easterners and vice-versa as its protagonist faces a large cultural divide.In the history of literary production ‘East’ has always been an attractive topic to explore for ‘Western’ authors. Westernwriters have mainly produced texts about the Middle East based on their travel accounts. However, in his seminal book, TheCrescent and the Rose: Islam and England during the Renaissance, Samuel Chew professes that there are two groups of travel-writers:‘arm-chair travelers who saw the East in their mind’s eye, and those who actually visited the lands and spoke from personalexperience’. (Chew, 1974. Indeed, Greig has written Damascus from first-hand experience, and not from prejudice or fantasy. Heexplains in a note on the text that Damascus is an unexpected result of theater workshops he has been leading in the Middle East in2000. He notes that the play is his exploration of the complexities of relations between the West and the Arab worlds. The playenvisions contradictory opinions on characterizing Western and Middle Eastern values. In Damascus Greig explores relationsbetween the self and ‘the other’, illustrates the complexities of cultural differences, subverts clichés and challengesmisconceptions. Through the main character, Greig not only objectifies and instrumentalizes Middle Eastern characters and issuesbut also projects definitions related to ‘self’. In a multicultural setting where East and West meet, the characters and the audiencesperceive each other’s similarities and differences in a global/transnational context Greig as a practicing artist in Damascus attempts to give voice to a Middle Eastern community in the Bakhtinian sense in thatit proposes a decentralized polyphony of the Middle Eastern world as opposed to centralized monological discourses. Indeed, atthe play’s end, the main character’s presumptions about the Middle East change. Although the play with its volatile and restlessMiddle Eastern setting has political references to freedom of speech, defining ‘the other’ and transnational relationships, itexplores the human condition in essence with the poet’s care and vigour.Greig clarifies that while the play is mostly ‘a comedy of cultural confusion’, it actually explores relationships between‘language and culture’ (Jackson, 2009. Following his trips to the Middle East, the playwright feels an urge to write the play. Hebelieves that most British playwrights do not experience the Middle East so there is a lack of plays that are set in that part of theworld. He has experienced that there is not a great tradition of playwriting in the Middle East, therefore there are not enoughplays available to be staged in Britain. Although the play is specifically entitled Damascus, the story could be set anywhere becausethe play is in fact a story of individuals, the choices they make, and how they treat one another. Indeed, the Westerners need tounderstand the relationships between individuals in order to grasp the complexity of Middle

Cadrage, décadrage et recadrage dans Baa Baa Black Sheep : A Jungle Tale de David Malouf et Michael Berkeley Patrimonial Deconstruction and Reconstruction in David Malouf and Michael Berkeley’s Baa Baa Black Sheep : A Jungle Tale  

Directory of Open Access Journals (Sweden)

Full Text Available This article discusses Michael Berkeley’s first opera, Baa Baa Black Sheep: A Jungle Tale. Premiered under the baton of Paul Daniel on July 3rd 1993 at the Cheltenham International Festival of Music, this opera is based on two texts by Rudyard Kipling: The Jungle Books (1894-1895 and “Baa, Baa, Black Sheep” from the short story collection Wee Willie Winkie and Other Stories, first published in 1888. The libretto was penned by the Australian poet, novelist, playwright and librettist, David Malouf. After a brief survey of some of the earliest transpositions of The Jungle Books, I analyse the way David Malouf deals with both texts. “Baa Baa Black Sheep” is used as the central element of his libretto, and episodes and characters from The Jungle Books are incorporated to draw parallelism between the main topics of the two texts. Both Malouf’s endeavour and Berkeley’s, through the music, aims at deconstructing the preposterous oldest transpositions of The Jungle Books and at focusing on the key elements of Kipling’s famous book, notably identity and hybridism, two important themes of colonial and postcolonial literature. The aim of David Malouf and Michael Berkeley is to address an adult audience and show that The Jungle Books are not only aimed at children as Disney’s or Baden Powell’s appropriations of the work could wrongly make us believe.Cet article porte sur Baa Baa Black Sheep: A Jungle Tale, le premier opéra de Michael Berkeley. Créé au Everyman Theatre de Cheltenham le 3 juillet 1993 sous la direction de Paul Daniel, cette œuvre est le fruit de la collaboration entre le compositeur britannique et l’écrivain australien David Malouf. Le livret de Malouf se fonde sur deux récits de Rudyard Kipling : la nouvelle autobiographique “Baa, Baa, Black Sheep” auquel l’opéra doit son nom et The Jungle Books. Après m’être intéressé aux premières transpositions musicales de The Jungle books, je montre comment Malouf utilise la nouvelle pour encadrer –au sens littéral du terme – des éléments extraits de The Jungle Books. Le but de Berkeley et de Malouf est de déconstruire les adaptations et réécritures du célèbre ouvrage de l’écrivain anglais qui ont précédé leur opéra en ancrant leur propre réécriture autour de l’identité et de l’hybridité, deux thèmes centraux dans le livre de Kipling ainsi que dans la littérature coloniale et postcoloniale. Contrairement aux reprises ou réappropriations de l’histoire par Disney et Baden Powell, qui pourraient nous faire penser, à tort, que l’ouvrage ne s’adresse qu’aux enfants, l’opéra de Malouf et de Berkeley vise donc avant tout un public d’adultes.

Entanglement in Theory Space  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We propose a new concept of entanglement for quantum systems: entanglement in theory space. This is defined by decomposing a theory into two by an un-gauging procedure. We provide two examples where this newly-introduced entanglement is closely related with conventional geometric entropies: deconstruction and AGT-type correspondence.

Abstract in english The following article attempts to develop one of the main topics present in the work of Chilean poet David Rosenmann-Taub: the search for transcendence through his poetic discourse, rooted in the memory to exorcize the presence of death. This search, in its themes and discourses, is produced by the [...] displacement of the text's subjects towards an origin, visualized as the nostalgia from a lost paradise that unfolds in the reencounter with family, friends, divine symbols and the roots of nature. In this task, the poet uses discursive strategies to exorcize the territory of death, attempting to prevent a journey towards pain, emptiness or nothing through the recognition of life and transcendence as well as through an imaginary upturn to a «country beyond», where past and future converge.

Dempster-Shafer theory and connections to information theory  

Science.gov (United States)

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.

Not intended for a beginner, this book further defi nes, describes, and explicates the classic grounded theory (GT method. Perspective III lays out various facets of theoretical coding as Glaser meticulously distinguishes classic GT from other subsequent methods. Developed many years after Glaser’s classic GT, these methods, particularly as described by Strauss and Corbin, adopt the grounded theory name and engender ongoing confusion about the very premises of grounded theory. Glaser distinguishes between classic GT and the adscititious methods in his writings, referring to remodeled grounded theory and its offshoots as Qualitative Data Analysis (QDA models.

G2 gauge theories  

CERN Document Server

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.

The Theory Of Gravity  

CERN Document Server

In the framework of the special theory of relativity, the relativistic theory of gravitation (RTG) is constructed. The energy-momentum tensor density of all the matter fields (including gravitational one) is treated as a source of the gravitational field. The energy-momentum and the angular momentum conservation laws are fulfilled in this theory. Such an approach permits us to unambiguously construct the gravitional field theory as a gauge theory. According to the RTG, the homogeneous and isotropic Universe is to be ``flat''. It evolves cyclewise from some maximal density to the minimal one, etc. The book is designed for scientific workers, post-graduates and upper-year students majoring in theoretical physics.

Statistical theory and inference  

CERN Document Server

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.

Extended Theories of Gravity  

CERN Document Server

Extended Theories of Gravity can be considered a new paradigm to cure shortcomings of General Relativity at infrared and ultraviolet scales. They are an approach that, by preserving the undoubtedly positive results of Einstein's Theory, is aimed to address conceptual and experimental problems recently emerged in Astrophysics, Cosmology and High Energy Physics. In particular, the goal is to encompass, in a self-consistent scheme, problems like Inflation, Dark Energy, Dark Matter, Large Scale Structure and, first of all, to give at least an effective description of Quantum Gravity. We review the basic principles that any gravitational theory has to follow. The geometrical interpretation is discussed in a broad perspective in order to highlight the basic assumptions of General Relativity and its possible extensions in the general framework of gauge theories. Principles of such modifications are presented, focusing on specific classes of theories like f (R)-gravity and scalar-tensor gravity in the metric and Pala...

Evolutionary game theory  

Science.gov (United States)

It is often the case that the best thing for an animal or plant to do depends on what other members of the population are doing. In more technical language, the fitnesses of different phenotypes are frequency-dependent. Evolutionary game theory has been developed to analyse such cases. In this paper I aim to do three things. First, I describe the concepts of evolutionary game theory in the context of a simple game, the Hawk-Dove game, and compare them with the concepts of classical game theory originating with Von Neumann and Morgenstern (1953) [1]. Second, I list some of the applications of the theory. Finally, I suggest how the theory can tell us something about the evolution of learning.

Democratic Neutrino Theory  

CERN Document Server

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.

EDUCATION IN ECONOMIC THEORY  

Directory of Open Access Journals (Sweden)

Full Text Available This paper aims to show the evolution of the role and importance of education in economic theory, especially in theoretical approaches to economic development after World War II. In order to find answers and to present a current issue - why and how certain countries have made progress while others have regressed in the development process, many theories and models explaining processes of growth and development have emerged and developed. By applying the method of analysis, synthesis and comparison, and based on earlier works, classification of theories of development has been made to analyze the evolution process of the role and importance of education in the development process. Presentation of the classification theory refers to: theories of economic development (the classical theory and contemporary models of development and underdevelopment and theories of interdependence of education and development (theory of human capital, human development and approach to the returns on investment in education. This paper presents the basic settings, ideas and thoughts of the key authors of these theories and models and the role of education and human capital in these theoretical approaches. Research has shown that the analysis of interdependence of education and economic development has been the subject of interest of researchers for many decades and that today, taking into account the high degree of development of theoretical approaches, there is no full commitment to the classic theories nor there is a unified approach to endogenous growth, but an approach that promotes the elements of both, considering education as the key factor of development of the 21st century.

Last Words: David's Mars Disarmed by Venus and the Graces (1824. Subjectivity, Death, and Postrevolutionary Late Style  

Directory of Open Access Journals (Sweden)

Full Text Available Completed as he was approaching death in 1825, Jacques-Louis David's final refractory history painting is an intricate summation of a life in politics and painting. The article attempts to re-interpret the canvas in relation to the dual problem of 'late style' and the condition of exile. I argue that this history painting invokes the metaphor of non-sex for the condition of exile; and as a late gesture stages an anomalous return to a pre-lapsarian eighteenth century. The painting, I conclude, reveals less the transcendent subjectivity of an artist approaching biological death, than the critical disarming of a once-radical neoclassical aesthetic itself, in its tragic late phase.

Set theory and physics  

Energy Technology Data Exchange (ETDEWEB)

Inasmuch as physical theories are formalizable, set theory provides a framework for theoretical physics. Four speculations about the relevance of set theoretical modeling for physics are presented: the role of transcendental set theory (i) in chaos theory, (ii) for paradoxical decompositions of solid three-dimensional objects, (iii) in the theory of effective computability (Church-Turing thesis) related to the possible {open_quotes}solution of supertasks,{close_quotes} and (iv) for weak solutions. Several approaches to set theory and their advantages and disadvantages for physical applications are discussed: Cantorian {open_quotes}naive{close_quotes} (i.e., nonaxiomatic) set theory, contructivism, and operationalism. In the author`s opinion, an attitude, of {open_quotes}suspended attention{close_quotes} (a term borrowed from psychoanalysis) seems most promising for progress. Physical and set theoretical entities must be operationalized wherever possible. At the same time, physicists should be open to {open_quotes}bizarre{close_quotes} or {open_quotes}mindboggling{close_quotes} new formalisms, which need not be operationalizable or testable at the time of their creation, but which may successfully lead to novel fields of phenomenology and technology.

M-Theory and Maximally Supersymmetric Gauge Theories  

CERN Document Server

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-Theory. We also briefly discuss the six-dimensional conformal field theory that is expected to arise on M5-branes. The construction of this theory is not only an important open problem for M-Theory but also a significant challenge to our current understanding of quantum field theory more generally.

Higher Gauge Theory and M-Theory  

CERN Document Server

In this thesis, the emerging field of higher gauge theory will be discussed, particularly in relation to problems arising in M-theory, such as selfdual strings and the so-called (2,0) theory. This thesis will begin with a Nahm-like construction for selfdual strings using loop space, the space of loops on spacetime. This construction maps solutions of the Basu-Harvey equation, the BPS equation arising in the description of multiple M2-branes, to solutions of a selfdual string equation on loop space. Furthermore, all ingredients of the construction reduce to those of the ordinary Nahm construction when compactified on a circle with all loops restricted to those wrapping the circle. The rest of this thesis, however, will not involve loop space. We will see a Nahm-like construction for the case of infinitely many selfdual strings, suspended between two M5-branes. This is possible since the limit taken renders the fields describing the M5-branes abelian. This avoids the problem which the rest of this thesis focuse...

The constancy of the spin of the photon was recently shown to lead to a new Lorentz-type transformation that relates the energy, rotational velocity, momentum of inertia, and angular momentum, where rotational invariance was the basis of the theory instead of the ordinary linear invariance of special relativity. In this paper the new group of transformations is shown to lead naturally to a special theory of relativity whose basic metric has an RxS3 topology rather than the familiar Minkowskian metric. Predictions by the theory are shown to be highly supported by experiment. (author)

Vacuum String Field Theory  

CERN Document Server

This is a brief review of vacuum string field theory, a new approach to open string field theory based on the stable vacuum of the tachyon. We discuss the sliver state explaining its role as a projector in the space of half-string functionals. We review the construction of D-brane solutions in vacuum string field theory, both in the algebraic approach and in the more general geometrical approach that emphasizes the role of boundary CFT. -- To appear in the Proceedings of Strings 2001, Mumbai, India.

Critical scattering theory  

International Nuclear Information System (INIS)

The origins of contemporary physical ideas and mathematical approaches in critical scattering theory are presented. In the framework of Gibbs' theory a general formula for the mean square fluctuation of an extensive thermodynamic parameter is derived. Critical scattering cross-section and the mean field approximation to the static and time-dependent pair correlation function are discussed. Static scaling, dynamic scaling and generalized static and dynamic susceptibility are treated. The extent to which theory agrees with experiment is briefly considered. (C.F.)

Dirac Kirchhoff diffraction theory  

CERN Document Server

Kirchhoff's scalar diffraction theory is applied throughout photon and electron optics. It is based on the stationary electromagnetic or Schr\\"odinger wave equation, and is useful in describing interference phenomena for both light and matter waves. Here, Kirchhoff's diffraction theory is derived from the relativistic Dirac equation, thus reformulated to work on Dirac spinors. The parallels with the "classic" scalar theory are highlighted, and a basic interpretation of the result obtained for the Fraunhofer diffraction limit is given. The goal of this paper is to emphasize the similarity between the two equations on the most fundamental level.

Reinterpretation of Skyrme Theory  

CERN Document Server

We identify the Faddeev-Niemi knot in Skyrme theory as a vortex ring made of a helical baby skyrmion (a twisted chromomagnetic vortex which is periodic in $z$-coodinate) with the periodic ends connected together. This allows us to interpret the knot as two quantized magnetic flux rings linked together, the first one winding the second $m$ times and the second one winding the first $n$ times, whose linking number $mn$ becomes the knot quantum number. This interpretation strongly suggests that the Skyrme theory could also describe a very interesting low energy physics in a completely different enviornment, which put the theory in a totally new perspective.

Economic Selection Theory  

DEFF Research Database (Denmark)

The present article provides a minimal description of the causal structure of economic selection theory and outlines how the internal selection dynamics of business organisations can be reconciled with selection in competitive markets. In addition to generic similarity in terms of the Darwinian principles of variation, continuity and selection, it is argued that economic selection theory should mimic the causal structure of neo-Darwinian theory. Two of the most influential explanations of economic evolution, Alchian's and Nelson and Winter's, are used to illustrate how this could be achieved.
