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

    OpenAIRE

    Wachter, Daniel Von

    2004-01-01

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

    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…

    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

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

    Science.gov (United States)

    Maciel, Duan

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

Abstract in english The main objective of this paper is to analyze the resource of land from the economic theory of David Ricardo as a first approach to the economic analysis of natural resources. This is done through an analytic review of the literature on the work of Ricardo and other authors that have covered this s [...] ubject. In this sense, the concept of ground rent is examined as well as the approaches around the so-called law of diminishing returns. Also, some critical thoughts are established about the approach to land rent. The results show that the concept of opportunity cost is absent from Ricardo's work on the income of land which implies a conceptual reconsideration on the income, in order to encompass the economic analysis on natural resources.

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.

    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.

    2013-06-01

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

    This paper is a response to two recent papers in The International Journal of Art Therapy, Inscape that set out positions in relation to art therapy theory. David Maclagan (2005) argues for the importance of ‘imagination’ in art therapy, and David Mann (2006) responds by defending a Freudian view of art therapy which he feels Maclagan has unfairly attacked on the grounds of it suppressing imagination.

    2004-01-01

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

    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.

  4. Paranoid, moi? : Erasing David

    DEFF Research Database (Denmark)

    Pedersen, Peter Ole; LØhmann Stephensen, Jan

    2010-01-01

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

  14. David Liberman's legacy.

    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'.

    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.

    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 ...

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

    DEFF Research Database (Denmark)

    Augier, Mie-Sophia

    2004-01-01

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

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

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.

  17. David Harvey’s contribution to urban sociology

    Directory of Open Access Journals (Sweden)

    Cvjetkovi? Marija

    2015-01-01

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

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

  5. Obituary: David Stanley Evans, 1916-2004

    Science.gov (United States)

    Bash, Frank N.

    2005-12-01

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

  11. Henry David Thoreau: Literary Transcendentalism

    2012-08-01

    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.

    Subset take-away is a two-player game involving a fixed finite set A. Players alternate choosing a proper, non-empty subset of A, with the condition that one may not name a set containing a set that was named earlier. A player unable to move loses. It was conjectured by David Gale that this game is always a second player win, and this was known to hold if A has no more than 5 elements. In this paper, we describe a technique called "binary star reduction" that often allows on...

    International Nuclear Information System (INIS)

    It is plausible to apply coasting beam criteria to bunches if one has short wavelength disturbances of the bunch and short memory wake fields, where short means short compared with a bunch length, for then one can argue that a piece of the bunch near the middle does not even know that the bunch has ends. Some other conditions probably required to validate this approach are discussed. The local Keil-Schnell criterion is derived from the local dispersion integral

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

He also plans that the revenue for the center will come from a mixture of eco-forestry with certified logging, ecotourism, sustainable production of non-timber products such as vines and latexes, bioprospecting, and the sale of forest management expertise. He further added that the program's success could change the way people value and use tropical forests. PMID:12295549

Mais precisamente, o texto destaca a estratégia de formalização adotada por Davi [...] d G. Champernowne em seu artigo intitulado "Unemployment, Basic and Monetary: the classical analysis and the keynesian", publicado em 1935-36 na Review of Economic Studies. Chamamos a atenção para o fato dele distinguir a teoria clássica da teoria de Keynes não apenas pelos pressupostos adotados por cada teoria, mas principalmente pela construção de subsistemas a partir de um sistema geral, com características recursivas (relações de causalidade) distintas. As explicações "em prosa", a descrição algébrica das funções comportamentais e condições de equilíbrio e a ilustração por meio de diagramas, além da escolha de conjuntos específicos de variáveis para representar cada uma das teorias e suas diferentes versões são aspectos deste artigo de Champernowne que merecem uma análise mais minuciosa. Abstract in english This paper aims at emphasizing a feature that has been somewhat neglected by studies dealing with the formalization of John Maynard Keynes's General Theory of Employment, Interest and Money (1936). Specifically, this paper stresses the formalization strategy David G.

We underline the fact that he distinguishes the Classical Analysis from the Keynesian not only by means of the different assumptions underlying each theory but mainly through the construction of sub-systems based on a general system, with distinctive recursive features (causal relations). His literary explanations, the algebraic descriptions of the behavioral functions and of the equilibrium conditions and his diagrammatical illustrations as well as the choice of specific groups of variables to stand for each of these theories (and variants) are features of this Champernowne's essay that deserve a more attentive assessment.

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

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.

    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.

  2. Waltz's Theory of Theory

    DEFF Research Database (Denmark)

    Wæver, Ole

    2009-01-01

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

    2011-12-01

    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.

  4. La analogía sociobiológica del desarrollo de la ciencia, la epistemología evolucionista de David Hull

    1996-12-01

    Full Text Available The eminent philosopher of biology, David Hull has proposed that a "general theory of evolution" can be advanced that would account for the evolution of organisms as well as for the evolution of scientific knowledge. According to Hull, competition among scientists plays in conceptual evolution a similar essential role as competition among organisms plays in biological evolution. Hull uses the sociobiology tradition to explain the apparently altruistic behavior of scientists in the search for knowledge.

    David Hull, uno de los filósofos de la biología más destacados en la actualidad, propone una "Teoría general de evolución" que, afirma, explica tanto la evolución de los seres vivos como el desarrollo del conocimiento científico. En el caso de la evolución conceptual, Hull sostiene que la competencia entre científicos juega un papel esencial en el avance de la ciencia, de manera similar a lo que ocurre en la evolución biológica. Entre otras cuestiones Hull recupera la tradición de la sociobiología para la explicación del comportamiento aparentemente altruista de los científicos en la búsqueda del conocimiento.

  5. Capacity theory on algebraic curves

    CERN Document Server

    Rumely, Robert S

    1989-01-01

    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...

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

Abstract in english In what is called the 'geographic turn' in contemporary philosophy, David Hume appears not only as a pioneer in using geographic metaphors to describe thinking but also his immanent empiricism had a decisive influence in Deleuze's work. The aim of this paper is to advance in this double register and [...] to present the geographic metaphors used by Hume to characterize his science of human nature or true philosophy, viz., the sceptic voyage, the conquest of the capital and mental geography.

Hemos querido, así, razonar los procedimientos internos de su poesía, interrogándola en su propia retórica, pero también en lo que esa retórica silencia o se niega a decir. En el complemento de estas dos preguntas, es donde se puede desplegar el rol que cumple la historia como principio de realidad de la obra incluso si no es explícitamente mencionada.The following paper will try to see in which perspectives a poetic work, such as the one by David Rosenmann-Taub, is feasible. The paper will try to understand the inner procedures of his poetry by questioning its own rhetoric, and by analyzing what this rhetoric denies to say or silences. As a complement to these two questions, the role of history will unravel so as to reveal its participation as a principle of reality in the work, even though it is not explicitly mentioned.

    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.

    Directory of Open Access Journals (Sweden)

    Andrew Murphie

    2012-06-01

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

    The 2012 Nobel prize in physics was awarded to David Wineland, together with Serge Haroche. David Wineland received the prize for ground-breaking experimental methods that enabled the measurement and manipulation of individual quantum systems, especially systems with trapped ions. He improved a trapped ion system and opened a new quantum world leading to quantum computation. He also realized optical atomic ion clocks with unprecedented precision through his experimental research. This article briefly reviews the history of trapped ion systems, the development of trapped-ion based quantum computation, and the development of the atomic ion clock, which are closely related to Wineland's achievements.

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.

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

On that account, electric fields are left intact by the operator, but magnetic fields are inverted. Albert sees no reason for the asymmetric treatment, and insists that neither field should be inver...

  17. 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)

    Hyldgaard, Per; Rahman, Talat S.

    2012-10-01

    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

  2. David Hume, Scepticism, Imagination and Political Philosophy

    Directory of Open Access Journals (Sweden)

    Renato Lessa

    2012-01-01

    Full Text Available The main purpose of my presentation is to explore some possible links between Hume’s philosophy of history and imagination. My point is that although Hume has clearly rejected narratives about human history and politics based on modern and rationalist versions of Natural Law, his own accounts on the matter were positively based on arguments that went well beyond some sort of retreat into bare empiricism or scattered historicism. Hume’s stance on the matter of history and politics, to my mind, can be interpreted as an effort to build a natural history of morals, justice and government in which imagination plays a non-negligible role. His criticism of rationalistic natural law theories does not entail the acceptance of empiricist or institutionalist points of view. Of course, empiricist and institutionalist languages are in the use, across Hume’s arrays of arguments, but it seems to me that these languages appear as submitted to the supremacy of imagination. In that sense, we may face in Hume’s theory of justice an alternative view, in the form of a breach between pure rationalistic and empiricist views.

Wallace, who was perhaps best known for this sprawling masterwork "Infinite Jest", was thoroughly catholic in his interests, and his work was peppered with references to everything from Continental philosophy to the behavior of cruise line passengers. Writing in this Tuesday's New York Times, fellow writer Verlyn Klinkenborg commented, "His writing could subsume the DNA of any language, any form it encountered, while remaining completely his own." During his 46 years, Wallace was awarded the Aga Khan Prize for Fiction, a MacArthur Foundation "Genius Grant", and also taught at Illinois State University and Pomona College. While many websites offer a way to comment on Wallace's work and life, the "In Memoriam" site created by Pomona College provides a fine glimpse into the effect he had on those he taught and influenced. One comment offered by Sean Pollack is particularly poignant: "We mourn for a humane and generous teacher and lover of the language."The first link will take interested parties to the New York Times' obituary for David Foster Wallace which appeared in print this Monday. The second link will lead visitors to a remembrance of Wallace from fellow writer David Lipsky. Moving on, the third link leads to a Syracuse Post-Standard piece from this Tuesday about Wallace's time in Syracuse in the early 1990s. The fourth link leads to the previously mentioned Pomona College "In Memoriam" site created for Wallace. The fifth link leads to a special edition of "Politics of Culture" hosted by bookworm Michael Silverblatt. Joined by book critic Anthony Miller they discuss Wallace's impact on fiction, his generation, and American culture. In addition, a collection of interviews with Wallace culled from the archives of KCRW's "Bookworm" program is also available. In terms of celebrating Wallace's life and writing, the sixth link is a very welcome find indeed. It contains links to many of his non-fiction pieces, including his very observant and wonderful take on a cruise-line adventure, "Shipping Out: On the (nearly lethal) comforts of a luxury cruise". The last and final link leads to a transcript of the honest and insightful commencement address that Wallace gave at Kenyon College in 2005.

    Israel is a small country with a population of around 7 million. The sole EMS provider for Israel is Magen David Adom (MDA) (translated as 'Red Shield of David'). MDA also carries out the functions of a National Society (similar to the Red Cross) and provides all the blood and blood product services for the country. Nationwide, the organisation responds to over 1000 emergency calls a day and uses doctors, paramedics, emergency medical technicians and volunteers. Local geopolitics has meant that MDA has to be prepared for anything from everyday emergency calls to suicide bombings and regional wars. MDA also prides itself in being able to rapidly assemble and dispatch mobile aid teams to scenes of international disasters. Such a broad range of activities is unusual for a single EMS organisation.

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

    International Nuclear Information System (INIS)

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

    This thesis concerns the ideas of ‘dialogue’ and ‘fragment’ in the work of the American liberal Roman Catholic theologian David Tracy (bn. 1939). Dialogue (or ‘conversation’) established itself as a dominant idea for Tracy in the 1980s, whereas the centrality of fragments first emerged for Tracy in the late 1990s, to complicate and refine his earlier thinking. Despite this historical sequence, however, the organisation of this thesis is thematic rather than essentially chronologic...

  17. Obituary: David Fulmer Bender, 1913-2004

    Science.gov (United States)

    Miller, Sylvia L.

    2004-12-01

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

Halberstam passed away this past Monday as the result of injuries he sustained during a car crash in the city of Menlo Park, California. True to his dedication to reporting, Halberstam was on his way to interview Y.A. Tittle, who played football for the New York Giants in the 1950s. Halberstam cut his teeth as the managing editor of The Harvard Crimson as an undergraduate, and then he moved on to write about the early years of the civil-rights movement for both the West Point Daily Times Leader and later for The Nashville Tennessean. He later went on to report on the war in Vietnam, and in 1964 he shared in a Pulitzer Prize with his colleagues at the New York Times. He went on to write over twenty books which explored the 1950s, the world of Michael Jordan (and by extension, the world of professional basketball), and perhaps his most well known work, "The Best and the Brightest". Perhaps Orville Schell, the dean of Berkeley's graduate school of journalism, said it best when he was asked how he felt about Halberstam's sudden death, and remarked that: "What can one say? The fragility of life sometimes just intrudes with a kind of savageness." The first link will take visitors to an excellent obituary of Halberstam written by the Baltimore Sun's own Larry Williams. The second link leads to a piece from Newsweek written by Evan Thomas who remembers his own encounters with Halberstam's work and sphere of influence.

    Full Text Available In Nice Work, David Lodge appropriates the model of the « condition-of-England novel » which he transposes into the 1980s. More than a mere transposition, Nice Work turns out to be an open rewriting of the Victorian novels quoted in epigraphs since the text, with its comical aspect and its auto-reflexive dimension, distances itself from realism. Far from being innocent, this rewriting considers critically the Thatcher era as well as contemporary literary theory and gives a discerning homage to Victorian novels.

  4. 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.)

    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].

  14. Set theory for category theory

    CERN Document Server

    Shulman, Michael A

    2008-01-01

    Questions of set-theoretic size play an essential role in category theory, especially the distinction between sets and proper classes (or small sets and large sets). There are many different ways to formalize this, and which choice is made can have noticeable effects on what categorical constructions are permissible. In this expository paper we summarize and compare a number of such "set-theoretic foundations for category theory," and describe their implications for the everyday use of category theory. We assume the reader has some basic knowledge of category theory, but little or no prior experience with formal logic or set theory.

  15. MOND theory

    CERN Document Server

    Milgrom, Mordehai

    2014-01-01

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

    2008-06-01

    Confabulation Theory [Hecht-Nielsen R. Confabulation theory. Springer-Verlag; 2007] is the first comprehensive theory of human and animal cognition. Here, we briefly describe Confabulation Theory and discuss experimental results that suggest the theory is correct. Simply put, Confabulation Theory proposes that thinking is like moving. In humans, the theory postulates that there are roughly 4000 thalamocortical modules, the “muscles of thought”. Each module performs an internal competition ( confabulation) between its symbols, influenced by inputs delivered via learned axonal associations with symbols in other modules. In each module, this competition is controlled, as in an individual muscle, by a single graded (i.e., analog) thought control signal. The final result of this confabulation process is a single active symbol, the expression of which also results in launching of action commands that trigger and control subsequent movements and/or thought processes. Modules are manipulated in groups under coordinated, event-contingent control, in a similar manner to our 700 muscles. Confabulation Theory hypothesizes that the control of thinking is a direct evolutionary outgrowth of the control of movement. Establishing a complete understanding of Confabulation Theory will require launching and sustaining a massive new phalanx of confabulation neuroscience research.

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

    Scientific Electronic Library Online (English)

    Hulisani, Ramantswana.

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

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

    Full Text Available David Falk, el que fuera el representante del jugador de baloncesto Michael Jordan, es una figura de referencia para el marketing deportivo. Falk contribuyó decisivamente a revitalizar el marketing deportivo, ayudó a construir lo que probablemente sea la relación comercial más importante del deporte (Jordan-Nike, y llevó hasta el extremo la filosofía de que en la negociación lo importante es que tu cliente llegue a conseguir el máximo dinero posible, más allá de que ese sea su valor de mercado o que el propio mercado pueda admitir esa inflación. En este artículo se repasan algunos de los hechos más destacados de su vida profesional y, desde una perspectiva crítica, se relacionan con varias cuestiones abiertas que el mundo académico y profesional del deporte continúa discutiendo. Abstract David Falk, former agent of the basketball player Michael Jordan, is a figure of reference for sports marketing. Falk was instrumental in revitalizing the sports marketing. He helped to build what is probably the most important relationship in sport business (Jordan-Nike, and strongly defended a radical philosophy of negotiation, where the most important is the maximization of client gains, regardless their true market value or if the market can admit such inflation. This article reviews some of the highlights of his career facts and, from a critical perspective, discusses several open issues related to the academic and professional world of sports. To achieve this aim, several recent contributions to the marketing and sports literature are commented.

  9. Uncertainty theory

    CERN Document Server

    Liu, Baoding

    2015-01-01

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

    2013-01-01

    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.

  19. Infinite potential the life and times of David Bohm

    CERN Document Server

    Peat, David

    1997-01-01

    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.

    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.

  3. Concept theory

    HjØrland, Birger

    2009-01-01

      Concept theory is an extremely broad, interdisciplinary and complex field of research related to many deep fields with very long historical traditions without much consensus. However, information science and knowledge organization cannot avoid relating to theories of concepts. Knowledge organizing systems (e.g. classification systems, thesauri and ontologies) should be understood as systems basically organizing concepts and their semantic relations. The same is the case with information retrieval systems. Different theories of concepts have different implications for how to construe, evaluate and use such systems. Based on "a post-Kuhnian view" of paradigms this paper put forward arguments that the best understanding and classification of theories of concepts is to view and classify them in accordance with epistemological theories (empiricism, rationalism, historicism and pragmatism). It is also argued that the historicist and pragmatist understandings of concepts are the most fruitful views and that this understanding may be part of a broader paradigm shift that is also beginning to take place in information science.  The importance of historicist and pragmatic theories of concepts for information science is outlined.

  4. Determinants of vigilance in a reintroduced population of Père David's deer

    Directory of Open Access Journals (Sweden)

    Wei ZHENG, Guy BEAUCHAMP, Xuelei JIANG, Zhongqiu LI, Qinglong YANG

    2013-04-01

    Full Text Available After being kept in captivity and isolated from natural predators for more than 1,200 years, Père David’s deer has been reintroduced in China and now occurs in a reserve where human activity is the only potential threat. Antipredator vigilance is an important component of survival for many prey animals in their natural habitat. Do deer still adjust vigilance as a function of risk after such a long period of relaxed predation pressure? Here, we examined vigilance levels in Père David’s deer groups as a function of group size, sex and level of human disturbance. The results showed that individual vigilance significantly decreased with group size in all-female groups but not in all-males or mixed-sex groups. In rutting season, males compete with one another and harass females, and we argue that vigilance is partly aimed at threatening males and that such vigilance increases with group size. This explains why overall vigilance did not vary with group size for males in general and for females in mixed-sex groups. Vigilance increased in more disturbed areas but in in male deer only. The results indicate that despite relaxed predation pressure over centuries, Père David’s deer can still adjust antipredator responses as a function of perceived risk. Such information may become useful in the rewilding programme now under way for this species in China [Current Zoology 59 (2: 265–270, 2013].

    2013-07-01

    We investigate local supersymmetry-breaking vacua in s-confining theories with gauge group Sp(2N). By adapting the general recipe developed by Shadmi and Shirman, we construct a realistic model based on dynamics of SQCD coupled with singlets which allows a spontaneously broken supersymmetry. Since the chiral superfields in model have R-charges R = 0 and R = 2 only, the tedious computations of Coleman-Weinberg potential can be greatly alleviated from the lesson of David Shih. We observe that the pseudomoduli fields are stabilized at the origin of moduli space at one-loop order with calculability being preserved.

  20. Einstein's Theory Fights off Challengers

    Science.gov (United States)

    2010-04-01

    Two new and independent studies have put Einstein's General Theory of Relativity to the test like never before. These results, made using NASA's Chandra X-ray Observatory, show Einstein's theory is still the best game in town. Each team of scientists took advantage of extensive Chandra observations of galaxy clusters, the largest objects in the Universe bound together by gravity. One result undercuts a rival gravity model to General Relativity, while the other shows that Einstein's theory works over a vast range of times and distances across the cosmos. The first finding significantly weakens a competitor to General Relativity known as "f(R) gravity". "If General Relativity were the heavyweight boxing champion, this other theory was hoping to be the upstart contender," said Fabian Schmidt of the California Institute of Technology in Pasadena, who led the study. "Our work shows that the chances of its upsetting the champ are very slim." In recent years, physicists have turned their attention to competing theories to General Relativity as a possible explanation for the accelerated expansion of the universe. Currently, the most popular explanation for the acceleration is the so-called cosmological constant, which can be understood as energy that exists in empty space. This energy is referred to as dark energy to emphasize that it cannot be directly detected. In the f(R) theory, the cosmic acceleration comes not from an exotic form of energy but from a modification of the gravitational force. The modified force also affects the rate at which small enhancements of matter can grow over the eons to become massive clusters of galaxies, opening up the possibility of a sensitive test of the theory. Schmidt and colleagues used mass estimates of 49 galaxy clusters in the local universe from Chandra observations, and compared them with theoretical model predictions and studies of supernovas, the cosmic microwave background, and the large-scale distribution of galaxies. They found no evidence that gravity is different from General Relativity on scales larger than 130 million light years. This limit corresponds to a hundred-fold improvement on the bounds of the modified gravitational force's range that can be set without using the cluster data. "This is the strongest ever constraint set on an alternative to General Relativity on such large distance scales," said Schmidt. "Our results show that we can probe gravity stringently on cosmological scales by using observations of galaxy clusters." The reason for this dramatic improvement in constraints can be traced to the greatly enhanced gravitational forces acting in clusters as opposed to the universal background expansion of the universe. The cluster-growth technique also promises to be a good probe of other modified gravity scenarios, such as models motivated by higher-dimensional theories and string theory. A second, independent study also bolsters General Relativity by directly testing it across cosmological distances and times. Up until now, General Relativity had been verified only using experiments from laboratory to Solar System scales, leaving the door open to the possibility that General Relativity breaks down on much larger scales. To probe this question, a group at Stanford University compared Chandra observations of how rapidly galaxy clusters have grown over time to the predictions of General Relativity. The result is nearly complete agreement between observation and theory. "Einstein's theory succeeds again, this time in calculating how many massive clusters have formed under gravity's pull over the last five billion years," said David Rapetti of the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) at Stanford University and SLAC National Accelerator Laboratory, who led the new study. "Excitingly and reassuringly, our results are the most robust consistency test of General Relativity yet carried out on cosmological scales." Rapetti and his colleagues based their results on a sample of 238 c

    Morgan, John Peter

    While few people toss around terms like Astroparticle Physics and Superstring Theory, we've all found ourselves staring out in to space on a starry night wondering what's out there, why it's arranged the way it is, and where it all came from. 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.

  6. “Silencio”: hearing loss in David Lynch's Mulholland Drive

    2014-11-01

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

  7. DAVID HUME AND THE CRITICAL EXAMINATION OF EMPIRICISM

    IONU? ?TEFAN

    2012-11-01

    Full Text Available The research is related to David Hume. This philosopher is described as being an empiricist, but it should be noted that the empiricism promoted by Hume represents the development up to the final consequences of this philosophical doctrine that should be subjected to the observability requirement. The core problem for Hume’s philosophy is the difficulty of causality thinking. The Scottish philosopher promotes a moderate and inconsistent skepticism because he does not doubt the permanency of facts. The Humean epistemology is mixed with elements belonging to some naïve ontology of a materialistic nature and with elements of a sensualistic psychology of an associationist type. The causality or the causal connection between events is based on a psychological belief, which has a pragmatic end for people, in that it offers us the psychological comfort of habitual events and the familiar existential. Causality refers to certain events that have already happened in a certain way, but it cannot constitute a necessary and sufficient basis for similar future events.

  8. Decay of Ethics in David Mamet’s American Buffalo

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

    2012-01-01

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

  11. Information Theory, Inference and Learning Algorithms

    Science.gov (United States)

    Mackay, David J. C.

    2003-10-01

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

  12. Plasma theory

    International Nuclear Information System (INIS)

    Among the broad spectrum of advances made by the Theory Section in the understanding of tokamaks and the ELMO Bumpy Torus (EBT), the following stand out as items of special importance to the fusion program: (1) The high beta tokamak approach pioneered and made credible at Oak Ridge National Laboratory (ORNL) has culminated in the demonstration of (1) stable equilibria at beta values as high as 10% for aspect ratio 4, (2) longevity of high beta cases in the presence of resistive skin diffusion, and (3) benign reaction the the full range of transport phenomena. For the EBT device, the simplified stability criteria previously used have been substantiated through more detailed analysis of kinetic effects, and most of the primary experimental observations have been explained on the basis of neoclassical transport theory

  13. Elastoplasticity theory

    CERN Document Server

    Hashiguchi, Koichi

    2014-01-01

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

  14. Communication theory

    DEFF Research Database (Denmark)

    Stein, Irene F.; Stelter, Reinhard

    2011-01-01

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

  15. 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

  16. 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).

  17. Testing theories

    International Nuclear Information System (INIS)

    This paper discusses some simple issues that arise in testing models, with a focus on models for low energy nuclear structure. By way of simplified examples, we illustrate some dangers in blind statistical assessments, pointing out especially the need to include theoretical uncertainties, the danger of over-weighting precise or physically redundant experimental results, the need to assess competing theories with independent and physically sensitive observables, and the value of statistical tests properly evaluated.

    Theory construction is a process, i.e., a set of state changes by an autonomous agent, or by an organism composed of several autonomous agents. In the first case, we may recall the approach of Pierce (1931) that considers three logical operations (inference rules) on a knowledge base, i.e., a set of propositions asserted to be valid: abduction, deduction, and induction. Abduction generates new hypotheses from which deduction derives predictions to be confirmed by experience. The confirmed hyp...

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

    Directory of Open Access Journals (Sweden)

    Orlando Alves dos Santos Junior

    2014-05-01

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

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

  8. 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

  10. 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

  5. Memory, modelling and Marr: a commentary on Marr (1971) ‘Simple memory: a theory of archicortex’

    2015-01-01

    David Marr's theory of the archicortex, a brain structure now more commonly known as the hippocampus and hippocampal formation, is an epochal contribution to theoretical neuroscience. Addressing the problem of how information about 10 000 events could be stored in the archicortex during the day so that they can be retrieved using partial information and then transferred to the neocortex overnight, the paper presages a whole wealth of later empirical and theoretical work, proving impressively prescient. Despite this impending success, Marr later apparently grew dissatisfied with this style of modelling, but he went on to make seminal suggestions that continue to resonate loudly throughout the field of theoretical neuroscience. We describe Marr's theory of the archicortex and his theory of theories, setting them into their original and a contemporary context, and assessing their impact. This commentary was written to celebrate the 350th anniversary of the journal Philosophical Transactions of the Royal Society. PMID:25750246

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

    Anne Jerslev

    2012-03-01

    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.

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

    Directory of Open Access Journals (Sweden)

    Mohammad Javad Movahedi

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

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

    Directory of Open Access Journals (Sweden)

    Baseler Michael W

    2007-11-01

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

    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 nat...

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

    Jardine, John F

    2015-01-01

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

  20. Bohmian mechanics. The physics and mathematics of quantum theory

    International Nuclear Information System (INIS)

    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.)

  3. Achmat Davids places the Cape Muslims on the South African linguistic map

    Scientific Electronic Library Online (English)

    Haron, Muhammed.

    Full Text Available South Africa's Cape Muslim religious leaders creatively contributed towards the formation of Afrikaans linguistics, an issue that the South African academia seemed to have ignored and overlooked. By the beginning of the 20th century, the literary output of these religious leaders developed to form a [...] unique genre of literature; a genre that is popularly referred to as "Arabic-Afrikaans" within the South African linguistic circles. Achmat Davids (1939-98), who may be regarded as the doyen of "Cape Islamic Studies," was among a handful of scholars who devoted much of his time to study carefully this type of literature. As a consequence of his labour, he produced one of the most significant contemporary works in South African linguistics. This review essay reflects upon the importance of Davids' path-breaking and invaluable study, which was recently co-edited by Hein Willemse and Suleman E. Dangor.

    David Bohm (1917-93) was a highly original and individual physicist. His novel ideas and profound intuition extended not only to the physical world but also to the nature of consciousness and society. Bohm regarded science as having become essentially fragmented in its approach to understanding physical reality and sought a more holistic physics based on order, transformation and flowing movement. His notion of an implicate order provides an unusual and exciting challenge for both teachers and students alike.

    Directory of Open Access Journals (Sweden)

    Deane-Peter Baker

    2011-08-01

    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.

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

    Directory of Open Access Journals (Sweden)

    Flegr Jaroslav

    2013-01-01

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

  18. Rationality, Theory Acceptance and Decision Theory

    Directory of Open Access Journals (Sweden)

    J. Nicolas Kaufmann

    1998-06-01

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

    String field theory is a candidate for a full non-perturbative definition of string theory. We aim to define string field theory on a space-time lattice to investigate its behaviour at the quantum level. Specifically, we look at string field theory in a one dimensional linear dilaton background. We report the first results of our simulations.

    Is string theory a fraud or one of the great scientific advances? Why do so many physicists work on string theory if it cannot be tested? This book provides insight into why such a theory, with little direct experimental support, plays such a prominent role in theoretical physics. The book gives a modern and accurate account of string theory and science, explaining what string theory is, why it is regarded as so promising, and why it is hard to test.

    We define the concept of a monotonic theory and show how to build efficient SMT (SAT Modulo Theory) solvers, including effective theory propagation and clause learning, for such theories. We present examples showing that monotonic theories arise from many common problems, e.g., graph properties such as reachability, shortest paths, connected components, minimum spanning tree, and max-flow/min-cut, and then demonstrate our framework by building SMT solvers for each of these t...

    Information is the basic concept of information theory. However, there is no definition of this concept that can encompass all uses of the term information in information theories and beyond. Many question a possibility of such a definition. However, foundations of information theory developed in the context of the general theory of information made it possible to build such a relevant and at the same time, encompassing definition. Foundations of information theory are built...

    Some personality psychologists have found a structural symbolic interactionist frame and identity theory relevant to their work. This frame and theory, developed in sociology, are first reviewed. Emphasized in the review are a multiple identity conception of self, identities as internalized expectations derived from roles embedded in organized networks of social interaction, and a view of social structures as facilitators in bringing people into networks or constraints in keeping them out, subsequently, attention turns to a discussion of the mutual relevance of structural symbolic interactionism/identity theory and personality theory, looking to extensions of the current literature on these topics.

  9. 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.

  10. Instinto e razão na natureza humana, segundo Hume e Darwin / Instinct and reason in human nature in David Hume and Charles Darwin

    2007-09-01

    Full Text Available Esta discussão pretende mostrar pontos relevantes de uma comparação entre a obra de David Hume e de Charles Darwin, no que toca às capacidades cognitivas humanas e de outros animais. Hume tem uma teoria que explica o conhecimento causal em termos de um instinto natural - o hábito. A presença de tal [...] instinto pode ser entendida remetendo-se a uma teoria geral da natureza, onde o mundo é entendido como governado por leis e regularidades constantes, e sem a suposição da interferência de um plano ou desígnio. Isto conduz Hume à aproximação entre a capacidade cognitiva humana e a de outros animais, que também manifestam um aprendizado instintivo do tipo causal. Darwin, por sua vez, menciona uma graduação de diversas capacidades de conhecimento, diferenciando a ação instintiva da ação que resulta de deliberação e inferência; e aponta para o fato de que muitos animais apresentam um grau significativo de comportamento inteligente. Seu mecanismo de evolução por seleção natural pretende explicar essas características, tanto no homem como nos animais. Disso resulta contemporaneamente uma corrente em epistemologia que tem recebido o nome de epistemologia evolutiva, a qual, ao seguir declaradamente Darwin, carece de uma interpretação mais detalhada do pensamento de Hume, que poderia, supõe-se, oferecer elementos para o tratamento de questões epistemológicas tais como a da capacidade para o conhecimento causal. Abstract in english This discussion intends to show some relevant elements, in order to establish a comparison between the works of David Hume and Charles Darwin concerning human and other animal's cognitive capacities. Hume develops a theory to explain causal knowledge in terms of a natural instinct - habit. The prese [...] nce of this instinct can be understood by reference to a general theory of nature that conceives the world governed by constant laws and regularities, without any supposition of interference of an external design or intention. This leads Hume in the way of an approximation between human cognitive capacities and the cognitive capacities of other animals, which also reveals instinctive learning of causal type. Darwin, on his turn, offers a graduation of many capacities of knowledge, distinguishing instinctive action from action resulting from deliberation and inference, and points to the fact that many animals have a significant degree of intelligent behavior. Darwinian mechanism of evolution by natural selection wants to explain this character, in humans as much as in animals. From that results the contemporary fashion in epistemology called evolutionary epistemology that, by following Darwin, lacks a more detailed interpretation of Hume's teaching that could, we suppose, offer elements to the treatment of questions such as the capacity of causal knowledge.

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.

  13. Neo-newtonian theories

    CERN Document Server

    Fabris, J C

    2015-01-01

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

    Marcin Mi?kowski

    2010-06-01

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

  15. 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.

    International Nuclear Information System (INIS)

    Many conformal field theory features are special versions of structures which are present in arbitrary 2-dimensional quantum field theories. So it makes sense to describe 2-dimensional conformal field theories in context of algebraic theory of superselection sectors. While most of the results of the algebraic theory are rather abstract, conformal field theories offer the possibility to work out many formulae explicitly. In particular, one can construct the full algebra A-bar of global observables and the endomorphisms of A-bar which represent the superselection sectors. Some explicit results are presented for the level 1 so(N) WZW theories; the algebra A-bar is found to be the enveloping algebra of a Lie algebra L-bar which is an extension of the chiral symmetry algebra of the WZW theory.

  3. 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)

    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.

    The nilpotent Becchi-Rouet-Stora-Tyutin (BRST), anti-BRST, dual-BRST and anti-dual-BRST symmetry transformations are constructed in the context of noncommutative (NC) 1-form as well as 2-form gauge theories. The corresponding Noether's charges for these symmetries on the Moyal plane are shown to satisfy the same algebra, as by the de Rham cohomological operators of differential geometry. The Hodge decomposition theorem on compact manifold is also studied. We show that noncommutative gauge theories are field theoretic models for Hodge theory.

  11. Introduction to string theories

    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

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

    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.

  17. Quantum field theory

    International Nuclear Information System (INIS)

    This book describes, as simply as is possible, the ideas and techniques of quantum field theory, on which is based our current understanding of subnuclear physics. In recent years this has advanced considerably with the discovery of charmed particles and the weak intermediate vector bosons predicted by gauge theories. After a brief survey of particle physics, the quantum theory of scalar and spinor fields, and then of gauge fields, is developed. The emphasis throughout is on functional methods, which have played a large part in modern field theory. The book concludes with a brief survey of 'topological' objects in field theory. The author assumes a knowledge of quantum mechanics and special relativity

  2. Family systems theory, attachment theory, and culture.

    Science.gov (United States)

    Rothbaum, Fred; Rosen, Karen; Ujiie, Tatsuo; Uchida, Nobuko

    2002-01-01

    Family systems theory and attachment theory have important similarities and complementarities. Here we consider two areas in which the theories converge: (a) in family system theorists' description of an overly close, or "enmeshed," mother-child dyad, which attachment theorists conceptualize as the interaction of children's ambivalent attachment and mothers' preoccupied attachment; (b) in family system theorists' description of the "pursuer-distance cycle" of marital conflict, which attachment theorists conceptualize as the interaction of preoccupied and dismissive partners. We briefly review family systems theory evidence, and more extensively review attachment theory evidence, pertaining to these points of convergence. We also review cross-cultural research, which leads us to conclude that the dynamics described in both theories reflect, in part, Western ways of thinking and Western patterns of relatedness. Evidence from Japan suggests that extremely close ties between mother and child are perceived as adaptive, and are more common, and that children experience less adverse effects from such relationships than do children in the West. Moreover, in Japan there is less emphasis on the importance of the exclusive spousal relationship, and less need for the mother and father to find time alone to rekindle romantic, intimate feelings and to resolve conflicts by openly communicating their differences. Thus, the "maladaptive" pattern frequently cited by Western theorists of an extremely close mother-child relationship, an unromantic, conflictual marriage characterized by little verbal communication and a peripheral, distant father, may function very differently in other cultures. While we believe that both theories will be greatly enriched by their integration, we caution against the application of either theory outside the cultures in which they were developed.

    The symmetry properties of the renormalized general gauge theory (the symmetries besides the gauge one are implied) are studied in the general case, when the transformation jacobian-like quantities in the functional integral are not ignored. It is shown that if the classical action of gauge theory has additional symmetry, then the renormalized effective action and the renormalized generating functional of proper vertices also possess definite symmetry

  4. Design Theory Projectability

    DEFF Research Database (Denmark)

    Pries-Heje, Jan; Baskerville, Richard

    2014-01-01

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

  5. 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.)

  6. Introduction to bifurcation theory

    International Nuclear Information System (INIS)

    Bifurcation theory is a subject with classical mathematical origins. The modern development of the subject starts with Poincare and the qualitative theory of differential equations. In recent years, the theory has undergone a tremendous development with the infusion of new ideas and methods from dynamical systems theory, singularity theory, group theory, and computer-assisted studies of dynamics. As a result, it is difficult to draw the boundaries of the theory with any confidence. In this review, the objects in question will be parameterized families of dynamical systems (vector fields or maps). In the sciences these families commonly arise when one formulates equations of motion to model a physical system. We specifically analyze how the time evolution near an equilibrium can change as parameters are varied; for simplicity we consider the case of a single parameter only

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

    CERN Document Server

    Silvescu, Adrian

    2011-01-01

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

    Boudet, Roger

    2011-01-01

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

    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.

  11. Gauge Theories of Gravitation

    CERN Document Server

    Blagojevi?, Milutin

    2012-01-01

    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...

  13. 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

    Enterocytozoon bieneusi is a zoonotic pathogen of the phylum Microspora that infects humans as well as a variety of animal species worldwide. While molecular epidemiologic studies have characterized this parasite in various hosts, isolates from many susceptible hosts have not yet been examined. In this study, E. bieneusi was isolated from 47 Pere David's deer (Elaphurus davidianus) in Henan, China and characterized via PCR analysis of the internal transcribed spacer (ITS) gene. E. bieneusi was detected in 16 out of 47 (34.0%) fecal specimens examined. Sequence analysis of the ITS revealed six known genotypes: type IV (4), EbpC (4), EbpA (4), BEB6 (2), COS-I (1), and COS-II (1). Of these, type IV, EbpC, and EbpA are known to cause human microsporidiosis worldwide, whereas the remaining genotypes are generally specific to ruminants. The present study indicated that Pere David's deer are naturally infected with E. bieneusi, predominantly with zoonotic genotypes, and may pose a risk for human transmission. PMID:25982030

  15. Corpses of Metaphor. Images of Death in David Leavitt and Jamaica Kincaid

    Directory of Open Access Journals (Sweden)

    Fiorenzo Iuliano

    2010-11-01

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

    2003-01-01

    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.

  17. Probabilities in quantum theory and probability theory

    International Nuclear Information System (INIS)

    A viewpoint is presented which, taken in probability theory and/or in quantum theory, will help place certain facts in a unified perspective and clarify their apparently enigmatic status. These facts are: (1) while the probabilities in probability theory are squared moduli of complex numbers; (2) the measure-theoretic apparatus of probability theory cannot accommodate the quantization rules for physical measurables and, above all; (3) the notion of limits on the accuracy attainable in simultaneous measurements on canonically conjugate variables does not appear in the theorems and algorithms of probability theory. The viewpoint rests on the intuitive but fundamental idea that measurable functions have non-unique inverses, and that an inner product representation of measures can be obtained whenever the function is differentiable. This idea is generalized to functions measurable on real rectangles and on complex plane. The formulas derived for measures are formally the same as those in quantum mechanics. The remainder of the development is based on the notion of a measurable-preserving point-to-point mapping from the range of these special measurable functions to an appropriate subset of a Hilbert space. Physical interpretations are attempted for each of the measure-theoretic constructs

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.

  19. String theory meets QCD

    International Nuclear Information System (INIS)

    String theory began life in the late 1960s as an attempt to understand the properties of nuclear matter such as protons and neutrons. Although it was not successful it has since developed a life of its own as a possible theory of everything - with the potential to incorporate quantum gravity as well as the other forces of nature. However, in a remarkable about face in the last five years, it has now been discovered that string theory and the standard theory of nuclear matter - QCD - might in fact describe the same physics. This is an exciting development that was the centre of discussion at a major workshop in Seattle in February. After spending 30 years as a possible theory of everything, string theory is returning to its roots to describe the interactions of quarks and gluons. (U.K.)

  20. Stationary scattering theory

    International Nuclear Information System (INIS)

    A complementary approach to the time dependent scattering theory for one-body Schroedinger operators is presented. The stationary theory is concerned with objects of quantum theory like scattering waves and amplitudes. In the more recent abstract stationary theory some generalized form of the Lippman-Schwinger equation plays the basic role. Solving this equation leads to a linear map between generalized eigenfunctions of the perturbed and unperturbed operators. This map is the section at fixed energy of the wave-operator from the time dependent theory. Although the radiation condition does not appears explicitely in this formulation it can be shown to hold a posteriori in a variety of situations thus restoring the link with physical theories

The reason for the difference between the two theories will be examined and the effect the this difference has on the way calculations are done in quantum theory will be examined.

  12. M-Theory and Maximally Supersymmetric Gauge Theories

    OpenAIRE

    Lambert, Neil

    2012-01-01

    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-...

  13. Electro-weak theory

    International Nuclear Information System (INIS)

    By electro-weak theory is meant the unified field theory that describes both weak and electro-magnetic interactions. The development of a unified electro-weak theory is certainly the most dramatic achievement in theoretical physics to occur in the second half of this century. It puts weak interactions on the same sound theoretical footing as quantum elecrodynamics. Many theorists have contributed to this development, which culminated in the works of Glashow, Weinberg and Salam, who were jointly awarded the 1979 Nobel Prize in physics. Some of the important ideas that contributed to this development are the theory of beta decay formulated by Fermi, Parity violation suggested by Lee and Yang, and incorporated into immensely successful V-A theory of weak interactions by Sudarshan and Marshak. At the same time ideas of gauge invariance were applied to weak interaction by Schwinger, Bludman and Glashow. Weinberg and Salam then went one step further and wrote a theory that is renormalizable, i.e., all higher order corrections are finite, no mean feat for a quantum field theory. The theory had to await the development of the quark model of hadrons for its completion. A description of the electro-weak theory is given

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

  15. Gauge theory of gravity

    International Nuclear Information System (INIS)

    Ideas on structure of gravitation theory and unification of gravitation and space-time with ordinary matter is developed. It is shown that realization of relativity and equivalence principles leads directly to the gauge theory (GT) of Lorentz group with spontaneously broken symmetry. This theory is a minimal gauge model and coinsides with Einstein-Kartan theory of gravitation with torsion. It is shown that in standard GT with Poincare group it is impossible to attach the importance of translation group gauge field to a tetrad gravitational field

  16. 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

    1998-01-01

    This is the written version of a short talk given at the University of Leipzig in December 1998. It reviews some general aspects of string theory from the viewpoint of the search for an unifying theory. Here, special emphasis lies on the motivation to consider string theory not only as the leading candidate for the unification of gravity and the other fundamental forces of nature, but also as a possible step towards a new understanding of nature and its description within the framework of physical models. Without going into details, some recent developments, including duality symmetries and the appearance of $M$--theory, are reviewed.

    The ability to understand and predict behavior in strategic situations, in which an individual's success in making choices depends on the choices of others, has been the domain of game theory since the 1950s. Developing the theories at the heart of game theory has resulted in 8 Nobel Prizes and insights that researchers in many fields continue to develop. In Volume 4, top scholars synthesize and analyze mainstream scholarship on games and economic behavior, providing an updated account of developments in game theory since the 2002 publication of Volume 3, which only covers work through the mi

  20. Empirical comparison of theories

    International Nuclear Information System (INIS)

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

  1. Proof theory an introduction

    CERN Document Server

    Pohlers, Wolfram

    1989-01-01

    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.

  2. Generalized etale cohomology theories

    CERN Document Server

    Jardine, John F

    1997-01-01

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

  3. Portfolio Theory Forward Testing

    Directory of Open Access Journals (Sweden)

    Marcus Davidsson

    2013-05-01

    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.

    Surgery theory, the basis for the classification theory of manifolds, is now about forty years old.

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

The book concludes with a bridge survey of ''topological'' objects in field theory and assumes a knowledge of quantum mechanics and special relativity

  12. Covariantizing Classical Field Theories

    CERN Document Server

    López, Marco Castrillón

    2010-01-01

    We show how to enlarge the covariance group of any classical field theory in such a way that the resulting "covariantized" theory is 'essentially equivalent' to the original. In particular, our technique will render any classical field theory generally covariant, that is, the covariantized theory will be spacetime diffeomorphism-covariant and free of absolute objects. Our results thus generalize the well-known parametrization technique of Dirac and Kucha\\v{r}. Our constructions apply equally well to internal covariance groups, in which context they produce natural derivations of both the Utiyama minimal coupling and St\\"uckelberg tricks.

  16. Rotor theories by Professor Joukowsky: Momentum theories

    DEFF Research Database (Denmark)

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

    2015-01-01

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

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

    Directory of Open Access Journals (Sweden)

    Walter Zidaric

    2009-10-01

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

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

    Science.gov (United States)

    Bern, Zvi

    2014-03-01

    As explained in the two previous talks by Lance Dixon and David Kosower, on-shell methods have had an important impact on our understanding of scattering amplitudes and their application to collider physics. In this talk I will describe examples where these ideas have also had impacts in more theoretical areas. The first example shows how these methods have led to the construction of all quantum corrections to specific scattering amplitudes in maximally supersymmetric gauge theory with a large number of color charges. An active area of current research is to do the same for more intricate generic amplitudes of the theory. A second example shows how on-shell methods have uncovered new algebraic structures in gauge-theory amplitudes that have applications to quantum gravity. The advances make it possible to carry out computations in quantum gravity that would have been hopeless with more traditional Feynman diagram methods and to elucidate a remarkable connection between gauge and gravity theories. The results from these investigations have renewed hope that highly supersymmetric gravity theories may be ultraviolet finite, contrary to the prevailing wisdom.

    In "Theory Is Personal," Allen Siegel MD, a Chicago psychoanalyst and Assistant Professor of Clinical Psychiatry at Rush University Medical Center, shares the very personal story of how he came to his theory. Sometimes we find our theory. Other times, Siegel argues, it is our theory that finds us. In this article Siegel catalogues his early encounters with figures--contemporary and real--from Sigmund Freud to influential department chairs to an analyst who would become legendary for introducing a bold new theory into the psychoanalytic canon. Charting key experiences that shaped his adoption of this new approach--a depression in response to his first patient, a clinical treatment with Heinz Kohut, and exposure to others who dared to challenge Freud--Siegel describes the theory that brought both himself and his patients to life. After outlining the principles that guide the new theory and practice known as self psychology, Siegel tells of the empathic ambiance that can now emerge in the consulting room. Finally, he shows how this new theory of human motivation provides not merely a rationale for psychotherapy but an explanatory apparatus for understanding human action in the world beyond the consulting room. He turns to a brief study of aggression and war, as expressed in a 1932 correspondence between Albert Einstein and Sigmund Freud, to illustrate how the understanding of aggression and war changes significantly when empathy is the field's data collecting instrument.

    These notes present some elements of causality theory. While they are not as complete as other treatments of the topic, there is some originality in that the whole approach is based on a definition of causal curves which allows to simplify many arguments. We keep track of the differentiability needed for various statements, obtaining a coherent theory for twice-continuously-differentiable metrics.

    This book discusses the main concepts of the Standard Model of elementary particles in a compact and straightforward way. The work illustrates the unity of modern theoretical physics by combining approaches and concepts of the quantum field theory and modern condensed matter theory. The inductive approach allows a deep understanding of ideas and methods used for solving problems in this field.

    Eling, C.; Jacobson, T.; Mattingly, D.

    2004-01-01

    We review the status of "Einstein-Aether theory", a generally covariant theory of gravity coupled to a dynamical, unit timelike vector field that breaks local Lorentz symmetry. Aspects of waves, stars, black holes, and cosmology are discussed, together with theoretical and observational constraints. Open questions are stressed.

  5. Inflation in String Theory

    Kim, Hang Bae

    Recent developments in string theory such as flux compactifications and moduli stabilization by non-perturbative effects of D-branes provided a solid framework where we discuss the realization of inflation in string theories. We review two prototype models, modular inflation and brane inflation, and discuss their observational consequences and outlook.

    When making decisions that impact student learning, college educators often consider previous experiences, precedent, common sense, and advice from colleagues. But how often do they consider theory? At a recent state-level educators' meeting, the authors of this article asked 50 student affairs educators about the use of theory in their practice.…

  9. Generic probabilistic theories : reconstruction of quantum theory

    International Nuclear Information System (INIS)

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

  10. Basic operator theory

    2001-01-01

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

  11. Statistical theory and inference

    CERN Document Server

    Olive, David J

    2014-01-01

    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.

  12. Theory of gravitational interactions

    CERN Document Server

    Gasperini, Maurizio

    2013-01-01

    This reference textbook is an up-to-date and self-contained introduction to the theory of gravitational interactions. The first part of the book follows the traditional presentation of general relativity as a geometric theory of the macroscopic gravitational field. A second, advanced part then discusses the deep analogies (and differences) between a geometric theory of gravity and the gauge theories of the other fundamental interactions. This fills a gap which is present in the context of the traditional approach to general relativity, and which usually makes students puzzled about the role of gravity. The necessary notions of differential geometry are reduced to the minimum, leaving more room for those aspects of gravitational physics of current phenomenological and theoretical interest, such as the properties of gravitational waves, the gravitational interactions of spinors, and the supersymmetric and higher-dimensional generalization of the Einstein equations. Theory of Gravitational Interactions will be o...

  13. Nonlocal continuum field theories

    CERN Document Server

    2002-01-01

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

  14. G2 gauge theories

    Maas, Axel

    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.

  15. Nonlinear spectral theory

    Appell, Jürgen; Vignoli, Alfonso

    2004-01-01

    In view of the eminent importance of spectral theory of linear operators in many fields of mathematics and physics, it is not surprising that various attempts have been made to define and study spectra also for nonlinear operators. This book provides a comprehensive and self-contained treatment of the theory, methods, and applications of nonlinear spectral theory. The only prerequisite for understanding this book is a modest background in functional analysis and operator theory. It is addressed to non-specialists who want to get an idea of the development of spectral theory for nonlinear operators in the last 30 years, as well as a glimpse of the diversity of the directions in which current research is moving.

  16. Lattice Gerbe Theory

    CERN Document Server

    Lipstein, Arthur E

    2014-01-01

    We formulate the theory of a 2-form gauge field on a Euclidean spacetime lattice. In this approach, the fundamental degrees of freedom live on the faces of the lattice, and the action can be constructed from the sum over Wilson surfaces associated with each fundamental cube of the lattice. If we take the gauge group to be $U(1)$, the theory reduces to the well-known abelian gerbe theory in the continuum limit. We also propose a very simple and natural non-abelian generalization with gauge group $U(N) \\times U(N)$, which gives rise to $U(N)$ Yang-Mills theory upon dimensional reduction. Formulating the theory on a lattice has several other advantages. In particular, it is possible to compute many observables, such as the expectation value of Wilson surfaces, analytically at strong coupling and numerically for any value of the coupling.

  17. Algebraic Quantum Field Theory

    Algebraic quantum field theory provides a general, mathematically precise description of the structure of quantum field theories, and then draws out consequences of this structure by means of various mathematical tools -- the theory of operator algebras, category theory, etc.. Given the rigor and generality of AQFT, it is a particularly apt tool for studying the foundations of QFT. This paper is a survey of AQFT, with an orientation towards foundational topics. In addition to covering the basics of the theory, we discuss issues related to nonlocality, the particle concept, the field concept, and inequivalent representations. We also provide a detailed account of the analysis of superselection rules by S. Doplicher, R. Haag, and J. E. Roberts (DHR); and we give an alternative proof of Doplicher and Roberts' reconstruction of fields and gauge group from the category of physical representations of the observable algebra. The latter is based on unpublished ideas due to Roberts and the abstract duality theorem for...

  18. Constructor Theory of Life

    Marletto, Chiara

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

    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.
