In the area of dynamic economics, David Cass's work has spawned a number of important lines of research, including the study of dynamic general equilibrium theory, the concept of sunspot equilibria, and general equilibrium theory when markets are incomplete. Based on these contributions, this volume contains new developments in the field, written by Cass's students and co-authors..
The Ontological Turn Misunderstood: How to Misunderstand David Armstrong’s Theory of Possibility
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.
Theory of Money of David Ricardo: Quantity Theory and Theory of Value
Directory of Open Access Journals (Sweden)
Susumu Takenaga
2003-07-01
Full Text Available What is to be underlined in characterizing the Ricardo’s quantity theory, is that it is a theory of determination of the value of money in a particular situation where money, whatever the form may be, shall be prevented from freely entering or leaving circulation. For Ricardo, the regulation of the value of money by its quantity is a particular case in which the adjustment of the market price to the natural price requires a long period of time. The quantitativist determination is not valid unconditionally, but only when the time of observation is shorter than that of this adjustment. The determination of the value of money is, in any case, barely linked to his theory of the value of commodities. Contrary to the commonly accepted interpretation, Ricardo did not apply to the determination of the value of money any theory of value different from that applied to commodities in general.

Dialectical materialism and the construction of a new quantum theory: David Joseph Bohm, 1917-1992
International Nuclear Information System (INIS)
This paper touches on some general questions of theory construction in physics, by presenting a biographical case study of David Bohm through the perspective of Fleckian thought-collectives and their thought-style. In the 1920s a small elite of physicists established the Copenhagen Interpretation of quantum mechanics as a new thought-style in the thought-collective of the physicists. In the following decade the Copenhagen Interpretation was transferred from Europe to the USA, from one thought-collective into another, and was integrated into a specific American thought-style. David Bohm was initiated in this mode of thought during his undergraduate studies at the Pennsylvania State College and his graduate studies at Caltech and the University of California at Berkeley.

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

Oral Histories in Meteoritics and Planetary Science—XIX: Klaus Keil
Sears, Derek W. G.
2012-12-01
Abstract- Klaus Keil (Fig. 1) grew up in Jena and became interested in meteorites as a student of Fritz Heide. His research for his Dr. rer. nat. became known to Hans Suess who--with some difficulty--arranged for him to move to La Jolla, via Mainz, 6 months before the borders of East Germany were closed. In La Jolla, Klaus became familiar with the electron microprobe, which has remained a central tool in his research and, with Kurt Fredriksson, he confirmed the existence of Urey and Craig's chemical H and L chondrite groups, and added a third group, the LL chondrites. Klaus then moved to NASA Ames where he established a microprobe laboratory, published his definitive paper on enstatite chondrites, and led in the development of the Si(Li) detector and the EDS method of analysis. After 5 years at Ames, Klaus became director of the Institute of Meteoritics at the University of New Mexico where he built up one of the leading meteorite research groups while working on a wide variety of projects, including chondrite groups, chondrules, differentiated meteorites, lunar samples, and Hawai'ian basalts. The basalt studies led to a love of Hawai'i and a move to the University of Hawai'i in 1990, where he has continued a wide variety of meteorite projects, notably the role of volcanism on asteroids. Klaus Keil has received honorary doctorates from Friedrich-Schiller University, Jena, and the University of New Mexico, Albuquerque. He was President of the Meteoritical Society in 1969-1970 and was awarded the Leonard Medal in 1988.1 Klaus Keil at the University of Hawai'i at Manoa, 2007.
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.

David A. Huffman (1925–1999) is best known in computer science for his work in information theory, particularly Huffman codes, and best known in origami as a pioneer of curved-crease folding. But during his early paper folding in the 1970s, he also designed and folded over a 100 different straight-crease origami tessellations. Unlike most origami tessellations designed in the past 20 years, Huffman's straight-crease tessellations are mostly three-dimensional, rigidly foldable, and have no loc...

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"X-REF REFID="9789814436571_0026FN001">X-REF> - a Jew - which during those years of violent struggle against cosmopolitanismb often proved an obstacle in looking for work. Second, during the years of mass repressions D. Kirzhnits' father had been arrested on treason charges (according to the charges, he had wanted to sell the Far East to Japan). After intensive investigation his father was released, but he lived only a little longer. Reports of this also could have impeded his acceptance. Third, Igor Evgenyevich didn't have enough weight in officials' eyes at that time and so was unable to overcome "first" and "second."...

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

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.

A remarkable theoretical physicist, Russian Academy of Sciences corresponding member David Abramovich Kirzhnits (1926-1998) left us a multifaceted and brilliant scientific legacy. Basic to his scientific vision was an understanding of the unity of physics as a reflection of the unity of nature. "...This unity," he said in his lectures for upper-level students at the Moscow State University department of physics, "emerges not only in the existence of general laws of nature, whose scope of action covers the widest range of scales - from 10-33 cm (the submicroscopic world) to 1028 cm (the Metagalaxy)... Moreover, it turns out that Nature also successfully uses specific physical mechanisms concurrently in the most diverse types of phenomena ... such as the `superconductor' mechanism for forming the masses of elementary particles"...

Paranoid, moi? : Erasing David
DEFF Research Database (Denmark)
Pedersen, Peter Ole; LØhmann Stephensen, Jan

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.

Generalized Stillinger--David Potential
Zhyganiuk, Igor
2012-01-01
We present an improved version of the Stillinger--David polarization potential of the intermolecular interaction in water. A clear algorithm of construction of a function describing the oxygen-hydrogen interaction in water molecules is formulated. A new approach to the modeling of a function screening the charge-dipole interaction on small distances is developed. To describe the long-range asymptotics of the intermolecular potential, the bare Stillinger--David potential is supplemented by a term related to the interaction of dipole moments of oxygen ions. In addition, we introduce a term involving a deformation of the electron shells of oxygen ions to the polarization component. These corrections allow us to successfully reproduce all essential results of quantum mechanical calculations of the interaction energy for water molecules obtained by Clementi. Analyzing the behavior of the dipole moment of a water molecule as a function of the intermolecular distance, we obtain the estimate of irreducible two-partic...

David Bohm's Hidden Variables Interpretation of Quantum Mechanics
Hall, Ned; Feldman, Gary; Wulsin, Wells
2001-04-01
This talk presents the hidden variables interpretation of quantum mechanics as proposed by David Bohm in 1952. Using a pilot-wave, Bohm’s theory reproduces the standard predictions of quantum mechanics while at the same time postulating that particles at all times are localized at definite positions. By way of introduction, the foundational issue of the quantum mechanics measurement problem will be discussed. The talk will then focus on how Bohm’s formulation of a hidden variables theory stands up to philosophical examination. Traditional objections to the theory, such as the EPR paradox, will be addressed, as well as the deeper metaphysical implications it holds for our view of the universe.

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'.

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 ...

Full Text Available Con el seudónimo de Pedro Pago, David Viñas escribió al comienzo de su carrera como narrador tres novelas sobre bandidos célebres argentinos: Chicho Grande, Chicho Chico y Mate Cocido. Publicadas en 1953 en la colección Crimen, estas novelas casi no han recibido atención. Este trabajo se propone mos [...] trar que estos textos adelantan aspectos fundamentales de la narrativa de Viñas, así como de sus guiones para el cine. Asimismo, estos relatos son significativos desde la perspectiva de la historia del policial argentino. En contraste con la historización llevada a cabo por Walsh ese año (1953), que pone en el centro el relato de enigma, las novelas de la colección Crimen proponen una tradición diferente, que atiende menos al misterio y la solución deductiva que a la biografía criminal y sus determinaciones sociales. Abstract in english In his early years as storyteller, David Viñas wrote-under the pseudonym of Pedro Pago-three novels about famous Argentine bandits: Chicho Grande, Chicho Chico and Mate Cocido. Published in 1953 in the collection Crime, these novels have received almost no attention. This paper intends to show that [...] these texts have some fundamental features and elements of Viñas' narrative work and screenplays of the subsequent years. Also, the three stories are significant from the perspective of the history of detective fiction in Argentina. In contrast to the history of the genre elaborated by Walsh the same year (1953), from a point of view that places in the center the classical whodunit story, this collection prove the existence of a different tradition, which pay less attention to the mystery and deductive resolution than to the criminal biography and its social determinations.

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

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.

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.

Physics Nobel prize 2004: Surprising theory wins physics Nobel
2004-01-01
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...

Review essay on David Laibman, Deep History: A Study in Social Evolution and Human Potential

Altug Yalcintas
2011-11-01
Full Text Available While historical materialism and evolutionism provide similar explanations and ideas regarding the cause of long-term social change, the two theories are rarely used in conjunction with one another. In Deep History,the author David Laibman addresses some of the standard questions of evolutionary social theory and attempts to bridge the two concepts, by showing that historical and materialist explanations are present in both Marxian and evolutionary interpretations of history. His goal: develop a Marxist theory of history from an evolutionist perspective, and surmount the traditional confines of historical materialism, so as to embrace evolutionary conceptions in explaining social change. However, the unbalanced research methodology limits the reach and depth of Laibman’s contribution. The two main shortcomings of his work are discussed in the following sections: The Audience Problem and The Evolutionary Problem.

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
Clássicos versus Keynes: a abordagem formal de David Champernowne

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

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.

Capacity theory on algebraic curves
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 [...] Abstract in spanish La filosofía de Hume fue, durante mucho tiempo, percibida como una filosofía escéptica.

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.

Then, his philosophy could be seen as a construction - over naturalistic basis - of a theory of knowledge and human nature. Some critics like Kevin Meeker intent to claim that the skeptic conclusions, present in Hume’s works makes impossible such a naturalistic view, prevailing after all the skeptical conclusion of the impossibility of knowledge. This enquiry wants to show, by an analysis of Hume’s texts, that the conceptions of knowledge, naturalism and even this conception of skepticism, applied to Hume’s philosophy is mistaken, and that the naturalistic outcome makes more sense, among the possible interpretations of Hume’s philosophy.

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.

In David Runciman’s new book on the nature of democratic crisis, the author looks at a history of such events from the early 20th Century to today. In doing so, he makes the argument that democracy is good at ‘muddling through’ crises, but less good at the long-term planning which averts them. Sean Kippin argues that it is a useful resource for understanding the nature of the particular events covered, though not necessarily a unifying theory of democratic crisis.

La economía emprendedora de David Audretsch

Full Text Available Pocos campos de la Economía cuentan con mejores bases teóricas que la Organización Industrial. Y David Audretsch ha contribuido en gran medida a mejorar el campo de la OI con sus modelos de emprendeduría y, también, con la inspiración y el estímulo que ha infundido a otros académicos. En el artículo publicado en este número monográfico, Audretsch plantea dos conceptos principales: uno es el modelo del filtro del conocimiento; el otro la idea de capital emprendedor. El concepto de filtro del conocimiento es central en la actual discusión sobre la relación entre la generación de conocimiento científico y tecnológico y su grado efectivo de traslación a innovaciones en el mercado. Muestra por qué y cómo los agentes que generan el conocimiento rara vez son los mismos que llegan a comercializarlos. Con frecuencia el puente es un emprendedor. La segunda idea aquí resaltada es el capital emprendedor y cómo la noción se ha popularizado gracias a la publicación de numerosos informes sobre tasas de creación de empresas. En este caso, aunque el concepto teórico sea valioso, ocurre que los estudios empíricos han arrojado pocos y contradictorios resultados.

Hacking the aesthetic: David Haines and Joyce Hinterding's new ecologies of signal
Directory of Open Access Journals (Sweden)
Andrew Murphie
2012-06-01
Full Text Available Award winning Australian electronic artists David Haines and Joyce Hinterding's installation work is discussed as “signal-work.” Their work reconfigures signal within original assemblages involving subtle audio, high resolution video (both recorded and animated, kilometers of coiled copper wire, antennae or home-built electronics, electrostatic disturbances, the like of very low frequency radiation from the Milky Way, and cross-signal processing. The article develops a context for thinking about the work in terms of Whitehead's process philosophy, as this is relevant to media theory, as well as concepts of plural ecology and ongoing differentiation drawn from Bateson and Guattari. Signal processing is seen as key to all this. The article argues that in Hinterding and Haines’ signal-work new sensations are produced, outside of the normal “syntax” of some models of aesthetic experience. This challenges some aspects of thinking about both aesthetics and political ecology.

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...

Les idées de David Bohm, indépendamment du scepticisme de ses collègues les plus traditionalistes, ont profondément influencé la physique du siècle dernier et ouvert une porte à la physique du nouveau millénaire. Grâce aussi aux contacts qu'il sut nouer avec des chercheurs d'autres branches du savoir, ses idées ont été accueillies avec beaucoup d'enthousiasme par les neuroscientifiques, les philosophes, les théologiens, les psychologues, les sociologues, les poètes, les artistes et les éducateurs. David Bohm avait peut-être pressenti qu'il existe une "physique de l'âme" et avec elle il voulait tracer un nouveau chemin pour une humanité à la dérive.
The 2012 Nobel Prize in physics and David Wineland
International Nuclear Information System (INIS)
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.

''Theory of theories'' approach to string theory
International Nuclear Information System (INIS)
We propose a new formulation of gauge theories as a quantum theory which has the gauge theory action S as its dynamical variable. This system is described by a simple actional I(S) (that is, an action for the action S) whose equation of motion gives the Batalin-Vilkovisky (BV) master equation for S. Upon quantization we find that our new formulation is reduced to something like a topological field theory having a BRST exact gauge-fixed actional. Therefore the present formulation can reproduce ordinary gauge theories since the path integral over S is dominated by the classical configuration which satisfies the BV master equation. This ''theory of theories'' formulation is intended to be applied to closed string field theory

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

DAVID: 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

Theology as dialogue and fragment: saying God with David Tracy
Palfrey, Barnabas Yeo; Pattison, George
2013-01-01
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 chronological. The ...

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.)
Obituary: David Fulmer Bender, 1913-2004
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

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].

Set theory for category theory
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.

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...

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.

Graph theory is a branch of discrete combinatorial mathematics that studies the properties of graphs. The theory was pioneered by the Swiss mathematician Leonhard Euler in the 18th century, commenced its formal development during the second half of the 19th century, and has witnessed substantial growth during the last seventy years, with applications in areas as diverse as engineering, computer science, physics, sociology, chemistry and biology. Graph theory has also had a strong impact in computational linguistics by providing the foundations for the theory of features structures that has emerged as one of the most widely used frameworks for the representation of grammar formalisms.

David Barker received the prestigious Richard Doll Prize in 2011 given by the International Epidemiology Association (IEA). This prize is given to a person who deserved to be a candidate for the Nobel Prize but would probably not be accepted by the Nobel Committee because of the way epidemiologic research is structured and conducted. In epidemiology we can seldom point towards a specific article or even a few articles or a single person who, by himself alone, changes the way we think. This article is protected by copyright.

Collapse Theories as Beable Theories
Bacciagaluppi, Guido
2010-01-01
I discuss the interpretation of spontaneous collapse theories, with particular reference to Bell's suggestion that the stochastic jumps in the evolution of the wave function should be considered as local beables of the theory. I develop this analogy in some detail for the case of non-relativistic GRW-type theories, using a generalisation of Bell's notion of beables to POV measures. In the context of CSL-type theories, this strategy appears to fail, and I discuss instead Ghirardi and co-worker...

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...

The film provided evidence of Duke's current racism, anti-Semitism, and pro-Nazi leanings. In a previous study with university students in Louisiana, the majority did not change their attitudes after watching the film (Eisenman, 1993). However, in the present study, students' attitudes showed change in an anti-Duke direction. The findings are discussed and reasons given for the differences between the two samples, and for the popularity of Duke, a former leader of the Ku Klux Klan. PMID:8237541
David of the Psalters: MT Psalter, LXX Psalter and 11QPsª Psalter
Scientific Electronic Library Online (English)
Hulisani, Ramantswana.
Full Text Available The focus of this paper is on the Davidic figure as presented in the Psalters-the MT Psalter, LXX Psalter and 11QPsª Psalter. David of the MT Psalter is the same figure we encounter in the LXX Psalter and 11QPsª Psalter; however, it is David as he is remembered uniquely in each of the Editorial Vari [...] ant Texts. The MT Psalter is compared with the LXX Psalter and 11QPsª Psalter. Contra Wilson, who argues that the MT Psalter deemphasises David when compared to the other textual witnesses, I argue that the MT Psalter is also susceptible to be read as a highly Davidic book. David is an important character in the Psalter and is the last of Israel's legendary figures mentioned within the bodies of the psalms. In the final analysis, the MT Psalter concludes with David, the sweet psalmist of Israel, remembered for directing Israel in the worship of Yahweh through unconditional praise, a praise resounding from every corner of the cosmos, Yahweh's temple.

Full Text Available David Mamet’s Oleanna addresses different notions such as power, hierarchy, education and language. According to Pierre Bourdieu, social agents compete for specific positions in a field and gain certain habitus (attitudes, dispositions, bodily hexis. In the process of socialization, agents struggle for different capitals (economical, cultural, social and symbolic all of which lead to “power”. Oleanna set in the field of academia concerns the struggle of the members for cultural capital which leads to symbolic capital. The shift of power in the play is the outcome of the shift of symbolic capital. Other Bourdieusian issues namely bodily hexis, misrecognition, feminine capital and IQ racism are also related to Oleanna. This article is an attempt at shedding light on how in Mamet’s play linguistic, cultural, and symbolic capital lead to shift of power in different discourses. The aim is to argue for the relevance of Bourdieu, a great theorist of culture, in reading David Mamet, a playwright preoccupied with contemporary American culture and its roots.

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.

This chapter explains how various spectroscopies can be used for probing the many-body quantum state of ultracold gas systems. It starts with a brief reminder of the basic theory of field-matter interactions. The general theory of linear response in the context of many-body quantum physics is then presented. A detailed theoretical description of RF spectroscopy, both the usual one and the momentum-resolved version, is given. This description applies to Raman spectroscopy as well. The basic theory behind Bragg spectroscopy and lattice modulation spectroscopy is also discussed. I explain how RF spectroscopy relates to the spectral function and how Bragg spectroscopy relates to the dynamical/static structure factor. The derivations are detailed and Green's functions are not used, so it is possible to follow this chapter based on simply knowing the basics of second quantization. Finally, self-consistent linear response theory and the use of sum rules is discussed in an overall manner.

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.
Possibility Theory versus Probability Theory in Fuzzy Measure Theory

2015-05-01
Full Text Available The purpose of this paper is to compare probability theory with possibility theory, and to use this comparison in comparing probability theory with fuzzy set theory. The best way of comparing probabilistic and possibilistic conceptualizations of uncertainty is to examine the two theories from a broader perspective. Such a perspective is offered by evidence theory, within which probability theory and possibility theory are recognized as special branches. While the various characteristic of possibility theory within the broader framework of evidence theory are expounded in this paper, we need to introduce their probabilistic counterparts to facilitate our discussion.

Set theory for category theory
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 ever...
Finite hedging in field theory models of interest rates.
Baaquie, Belal E; Srikant, Marakani
2004-03-01
We use path integrals to calculate hedge parameters and efficacy of hedging in a quantum field theory generalization of the Heath, Jarrow, and Morton [Robert Jarrow, David Heath, and Andrew Morton, Econometrica 60, 77 (1992)] term structure model, which parsimoniously describes the evolution of imperfectly correlated forward rates. We calculate, within the model specification, the effectiveness of hedging over finite periods of time, and obtain the limiting case of instantaneous hedging. We use empirical estimates for the parameters of the model to show that a low-dimensional hedge portfolio is quite effective. PMID:15089384

Full Text Available En este artículo, se trata de presentar algunas opiniones criticas sobre el significado de "verdad" lingüístico y pragmático, en la obra Needs, Values, Truth de Wiggins. Se explora el sentido de la "verdad" en su contexto gramatical y en su significación contextual. Es difícil suponer un concepto "absoluto" de verdad, sobre todo si lo relacionamos con el con texto ético de la acción. Referidas la ideas de Wiggins a Williams, David son, Peirce, Wittgenstein, Habermas, se considera que la suposición de que la verdad está asociada a la analogía, la identidad, la equivalencia, no es suficiente para obtener el grado de certeza de las cosas. Es ne cesaria una indagación más profunda sobre la intencionalidad y el relativismo donde la "verdad" se funda.
David Duke, running for governor, proposes tattooing people with HIV.
1995-05-19
Former Ku Klux Klan leader, David Duke, planning a second run for governor of Louisiana, said he would curb the AIDS epidemic by tattooing people who are infected with HIV. His suggestion is to put indelible, glow-in-the-dark tattoos on the genitals of people infected with HIV. According to Duke, it may sound very draconian but it would not demean people. He also believes that tattooing would be legal because courts have a history of supporting the quarantining and institutionalizing of people with infectious diseases, such as tuberculosis. Duke said Cuba has had some success in using quarantines to reduce HIV infection, but he does not think it would work in the United States because it would cost too much. According to Duke, many people who get HIV from irresponsible behavior do not tell their partners that they have AIDS--these people are mad at the world and engage in dangerous behaviors even more.

David Rumsey Map Collection: 1979 California Water Atlas
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.
Quantenmechanik im Kalten Krieg David Bohm und Richard Feynman
Forstner, Christian
2007-01-01
Mitte des 20. Jahrhunderts entwickelten David Bohm und Richard Feynman zwei grundlegend verschiedene Ansätze der moderne Quantenmechanik: Bohm eine realistische Deutung mit Hilfe verborgener Parameter und Feynman den Pfadintegralformalismus. Dies ist umso bemerkenswerter, weil beide Physiker von ähnlichen Voraussetzungen ausgingen und aus ähnlichen Zusammenhängen stammten. Durch ihren vergleichenden Ansatz bietet diese Studie mehr als einen Beitrag zur Geschichte der Quantentheorie. Mit der Frage nach den sozialen und kulturellen Bedingungen der Theoriebildung ist sie darüberhinaus von wissenschaftssoziologischem und wissenschaftstheoretischem Interesse. Die anfangs ähnliche und später unterschiedliche Einbindung der beiden Wissenschaftler in die Scientific Community erlaubt es überdies zu untersuchen, welchen Anpassungsdruck die jeweilige Gruppe auf den individuellen Wissenschaftler und die Kernbestandteile seiner Forschungen ausübt und welche neuen Freiheitsgrade für die Theoriebildung entstehen, ...

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

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].

Two comparative studies were undertaken using adult, female red and Père David's deer to examine the ovulatory response of these animals to a superovulation regimen and fertilization rates following inter- and intraspecific laparoscopic insemination. In Expt 1 six Père David's deer and 12 red deer hinds were treated during the breeding season with an intravaginal progesterone-impregnated controlled internal drug release device (CIDR) for 14 days, with 200 iu pregnant mares' serum gonadotrophin (PMSG) administered 72 h before the device was withdrawn and eight injections of ovine FSH given at 12 h intervals starting at the time of PMSG administration. Oestrous behaviour began one day after CIDR device withdrawal (Père David's deer: 24.00 +/- 2.32 h; red deer: 24.60 +/- 2.23 h). The duration of oestrus was greater in Père David's deer than in red deer (17.50 +/- 1.43 h and 8.25 +/- 3.25 h, respectively, P < 0.001). The peak LH surge of Père David's deer was 68.65 +/- 4.74 ng ml-1 occurring 29.00 +/- 2.41 h after removal of the CIDR devices. In comparison, the peak LH surge in red deer was 17.09 +/- 3.64 ng ml-1 (P < 0.001), occurring 24.00 +/- 0.00 h after CIDR device withdrawal. Pre-surge concentrations of LH were also greater (P < 0.001) in Père David's deer (1.37 +/- 0.11 ng ml-1) than in red deer hinds (0.41 +/- 0.02 ng ml-1).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8021886

Full Text Available Representative democracy has been based on the idea that interest groups form parliaments through competitive elections, and legislate in favour of their supporters. Declining electoral participation, rise of populist rightwing parties, contingent coalitions, personalized electoral success and scandaldriven politics indicate a crisis in representative democracy. Mass society theories after the Second World War predicted a decline of democracy on the basis of homogenisation of mass consumption societies. The threat was seen to involve totalitarian rule, combined with bureaucracy serving the interests of elites. This paper examines the underlying presuppositions of mass society theory, and argues that the homogeneity argument is insufficient to fit the realities. Following David Riesman, it is argued that the otherdirected character growsfrom unstable interest group identities, but its determinant is not sameness but agency and therefore difference. To have agency is to orient oneself to others as a self, as unique, separate and autonomous subject. This is vindicated by trends in public administration since the 1980s, which stress citizens’ selfcontrol,autonomy and partnership rather than conformity. Political disputes arise around contradictions between difference and autonomy in societies where agency is a principle of justification. Universal autonomy requires homogeneity but agency stresses difference and uniqueness.

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

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.

Information Theory, Inference and Learning Algorithms
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.

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).

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...

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).

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

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

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

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.

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
Clássicos versus Keynes: a abordagem formal de David Champernowne

Full Text Available Este texto tem por objetivo ressaltar um aspecto que não tem sido tratado com a devida profundidade na literatura que estuda a formalização da Teoria Geral do Emprego, dos Juros e da Moeda de John Maynard Keynes (1936. 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.
Transatlantic Miscommunication in David Hare’s Drama Stuff Happens

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.

The U.S. Department of Energy (DOE) Oak Ridge Office (ORO) of Environmental Management (EM) requested the technical assistance of Oak Ridge Institute for Science and Education (ORISE) to characterize a tract of land associated with the David Witherspoon, Incorporated (DWI) Volunteer Equipment and Supply Company (VESC). This tract of land (hereinafter referred to as Screen Arts) is located in the Vestal Community in the 2000-block of Maryville Pike in south Knoxville, Tennessee, as shown in Figure A-1. This tract of land has been used primarily to store salvaged equipment and materials for resale, recycle, or for disposal in the former landfill once operated by DWI. The DWI Site industrial landfill and metal recycling business had been permitted by the Tennessee Division of Radiological Health to accept low-level radiologically contaminated metals. DWI received materials and equipment associated with operations from DOE sites, including those in Oak Ridge, Tennessee; Paducah, Kentucky; and Portsmouth, Ohio. It is likely that items stored at Screen Arts may have contained some residual radiological materials.
Sir David Brewster's changing ideas on the plurality of worlds
de Asúa, Miguel
2006-06-01
In the course of his long life the Scottish physicist David Brewster wrote copiously about the plurality of worlds. More Worlds than One (1854), perhaps his strongest statement on the question, was written as an answer to William Whewell's On the Plurality of Worlds (1853), which argued that life was a privilege of the Earth. Brewster's ideas changed drastically along the years in many crucial issues such as the habitability of the Sun and the Moon, the possibility that extraterrestrials could be different from humans, and the occupation of the Earth by intelligent races in the distant past. This paper succinctly surveys Brewster's main lines of thought about the plurality of worlds underlining the significance of his first two articles devoted exclusively to this topic. They were published in 1838 in The Monthly Chronicle, and affirm the habitability of the planets while denying that of the Moon. As is the case with many Victorian scientists, belief in pluralism was for Brewster part and parcel of a complex of ideas and attitudes in which it is hard to distinguish science from religion. I shall argue that a fair number of the shifting opinions and inconsistencies detectable in Brewster's ideas on the plurality of worlds can be attributed to the fact that these were used as pliable apologetic instruments in his scientific writings, many of which are permeated by strong religious concerns.

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.

We analyze how string theory dualities may be described in M theory. T dualities arise from scalar-vector dualities in the worldvolume of the membrane of M theory. ``Electric-magnetic'' dualities arise from a duality transformation in M theory compactified on a 3-torus, which takes the membrane into a fivebrane wrapped around the 3-torus.

Game semantics is a valuable source of fully abstract models of programming languages or proof theories based on categories of so-called games and strategies. However, there are many variants of this technique, whose interrelationships largely remain to be elucidated. This raises the question: what is a category of games and strategies? Our central idea, taken from the first author's PhD thesis, is that positions and moves in a game should be morphisms in a base category: playing move m in po...

This book is a concise, yet carefully written, introduction to modern graph theory, covering all its major recent developments. It can be used both as a reliable textbook for an introductory course and as a graduate text: on each topic it covers all the basic material in full detail, and adds one or two deeper results (again with detailed proofs) to illustrate the more advanced methods of that field. This second edition extends the first in two ways. It offers a thoroughly revised and updated chapter on graph minors, which now includes full new proofs of two of the central Robertson-Seymour theorems (as well as a detailed sketch of the entire proof of their celebrated Graph Minor Theorem). Second, there is now a section of hints for all the exercises, to enhance their value for both individual study and classroom use.

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

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

Evaluation of two dental identification computer systems: DAVID and WinID3.
Al-Amad, S H; Clement, J G; McCullough, M J; Morales, A; Hill, A J
2007-06-01
Human identification, by comparing dental characteristics, is considered to be one of the most reliable, accurate and rapid methods of resolving the identity of visually un-identifiable deceased persons. In recent decades computer programs have evolved to aid odontologists by suggesting records that have similar dental features. The aim of the present study was to compare two of those programs; Disaster And Victim IDentification (DAVID) and WinID3 in terms of effectiveness, accuracy and speed of data entry and to further compare them with the efficiency of the classical method of manually matching postmortem and antemortem dental records. An open disaster was simulated whereby 52 fragmented remains made of acrylic replicas and 77 provisional victims were represented on Interpol F2 postmortem and antemortem forms. The results assessed were the first seven possible matches made by each program. Manual matching of dental characteristics performed better than both programs (P<0.001) yielding 29 identifications. Eleven and six positive matches were the result of the DAVID and the WinID3 programs respectively (P=0.185). Data entry was quicker for WinID3. It was concluded that both programs are still not as accurate as the time-consuming manual matching method. The difference in performance between the DAVID and the WinID3 programs was attributed to the inclusion of more comparable dental characteristics, the inclusion of the type of dentition (deciduous or permanent) and the weighting of those characteristics by the DAVID program.

Composite Photon Theory Versus Elementary Photon Theory
Perkins, Walton A
2015-01-01
The purpose of this paper is to show that the composite photon theory measures up well against the Standard Model's elementary photon theory. This is done by comparing the two theories area by area. Although the predictions of quantum electrodynamics are in excellent agreement with experiment (as in the anomalous magnetic moment of the electron), there are some problems, such as the difficulty in describing the electromagnetic field with the four-component vector potential because the photon has only two polarization states. In most areas the two theories give similar results, so it is impossible to rule out the composite photon theory. Pryce's arguments in 1938 against a composite photon theory are shown to be invalid or irrelevant. Recently, it has been realized that in the composite theory the antiphoton does not interact with matter because it is formed of a neutrino and an antineutrino with the wrong helicity. This leads to experimental tests that can determine which theory is correct.

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

Full Text Available 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

A unified physical theory called U theory, that is different from M theory, is defined and characterized. U theory, which includes spinor and twistor theory, loop quantum gravity, causal dynamical triangulations, E-infinity unification theory, and Clifford-Finslerian unifications, is based on physical tradition and experimental foundations. In contrast, M theory pays more attention to mathematical forms. While M theory is characterized by supersymmetry string theory, U theory is characterized by non-supersymmetry unified field theory.

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...

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/.
The scanpath theory: its definitions and later developments
Privitera, Claudio M.
2006-02-01
The scanpath theory was defined in 1971 by David Noton and Lawrence Stark in two articles that appeared in Science1 and Scientific American2, and since then it has been considered one of the most influential theory of vision and eye movements. The scanpath theory explains the vision process in a topdown fashion by proposing that an internal cognitive representation controls not only the visual perception but also the related mechanism of active looking eye movements. Evidence supporting the scanpath theory comes from experiments showing the repetitive and idiosyncratic nature of eye movements during experiments with ambiguous figures, visual imagery and dynamic scenes. Similarity metrics were defined in our analysis procedures to quantitatively compare and measure the sequence of eye fixations in different experimental conditions. More recent scanpath experiments performed using different motor read-out systems have served to better understand the structure of the visual image representation in the brain and the presence of several levels of binding. A special emphasis must be given to the role of bottom-up conspicuity elaboration in the control of the scanpath sequence and interconnection of conspicuity with such higher level cognitive representations.
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.

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.)
The philosophy of set theory an historical introduction to Cantor's paradise
Tiles, Mary
2004-01-01
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
Rationality, Theory Acceptance and Decision Theory

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.

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.

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 introduce an abstract topos-theoretic framework for building Galois-type theories in a variety of different mathematical contexts; such theories are obtained from representations of certain atomic two-valued toposes as toposes of continuous actions of a topological group. Our framework subsumes in particular Grothendieck's Galois theory and allows to build Galois-type equivalences in new contexts, such as for example graph theory and finite group theory.

The mathematics of classical probability theory was subsumed into classical measure theory by Kolmogorov in 1933. Quantum theory as nonclassical probability theory was incorporated into the beginnings of noncommutative measure theory by von Neumann in the early thirties, as well. To precisely this end, von Neumann initiated the study of what are now called von Neumann algebras and, with Murray, made a first classification of such algebras into three types. The nonrelativisti...
Going beyond perturbation theory: Parametric Perturbation Theory
Amore, Paolo

We devise a {\\sl non--perturbative} method, called {\\sl Parametric Perturbation Theory} (PPT), which is alternative to the ordinary perturbation theory. The method relies on a principle of simplicity for the observable solutions, which are constrained to be linear in a certain (unphysical) parameter. The perturbative expansion is carried out in this parameter and not in the physical coupling (as in ordinary perturbation theory). We provide a number of nontrivial examples, wh...

Full Text Available The house of Eli and the house of David: how God can go back on God,s word. The interpretation of the rejection of Abiathar in terms of the Eli tradition offers an important indication of the intention of the Succession Narrative. The work does not only have a positive as well as a negative tendency as far as the Davidic dynasty is concerned, but the relationship between these two sides is one of conditionality. Therefore the critical aspect of the Succession Narrative contains both acceptance and warning. A sketch of the broader theological framework is given in which the interplay of God's love and his demand of obedience is understood in its historical context, including the redactional perspective.
David Barker, Buruli ulcer and the epidemiology of a neglected tropical disease.
Phillips, D I W
2015-10-01
In 1969, David Barker, his wife and four children moved to Uganda to work at Makerere Medical School in the capital Kampala. During the 1960s, Makerere had become a research and teaching centre with an international reputation based on the work of Trowell, Burkitt, Hutt and many others who had pioneered studies explaining the disease patterns in the West Nile area on the basis of the local climate, nutrition and lifestyle. David Barker was funded by the Medical Research Council to carry out research on a poorly understood disease, Buruli ulcer, joining Scottish surgeon Wilson Carswell, who was later to achieve fame as the role model for Dr Garrigan in Giles Foden's novel The Last King of Scotland.

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.

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

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

PEOPLE IN PHYSICS: David Bohm and the implicate order: a new paradigm for physics teachers
Bettany, Laurence
1998-11-01
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.

Measures recommended to verify the placement of a DAVID detector in the accelerator head
International Nuclear Information System (INIS)
The technological development affects not only the equipment used to perform radiation therapy treatments, but also to teams that are at our disposal to verify the proper administration of the same. One of these new teams is the 'device for verification of IMRT Deliveries advanced' (DAVID). The DAVID chamber is a multi-wire transmission is placed in a linear accelerator head are firmly anchored to it. The design is intended to be one of the wires passing through the center of each pair of collimator blades along its entire length. This forces each has a design for multi leaf collimator system. In addition, each team has a set of screws that allow fine tuning of both the source-wire distance and the center of the transmission chamber in the radiation field of the accelerator. The work aims make a recommendation, based on our experience, a set of measures to be taken to verify the correct placement of DAVID in the field of treatment, or alternatively, help to make the necessary adjustment.

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

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.
Separation-individuation theory and attachment theory.
Blum, Harold P
2004-01-01
Separation-individuation and attachment theories are compared and assessed in the context of psychoanalytic developmental theory and their application to clinical work. As introduced by Margaret Mahler and John Bowlby, respectively, both theories were initially regarded as diverging from traditional views. Separation-individuation theory, though it has had to be corrected in important respects, and attachment theory, despite certain limitations, have nonetheless enriched psychoanalytic thought. Without attachment an infant would die, and with severely insecure attachment is at greater risk for serious disorders. Development depends on continued attachment to a responsive and responsible caregiver. Continued attachment to the primary object was regarded by Mahler as as intrinsic to the process of separation-individuation. Attachment theory does not account for the essential development of separateness, and separation-individuation is important for the promotion of autonomy, independence, and identity. Salient historical and theoretical issues are addressed, including the renewed interest in attachment theory and the related decline of interest in separation-individuation theory. PMID:15222460

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.

In Higher Topos Theory, Jacob Lurie presents the foundations of this theory, using the language of weak Kan complexes introduced by Boardman and Vogt, and shows how existing theorems in algebraic topology can be reformulated and generalized in the theory's new language. The result is a powerful theory with applications in many areas of mathematics. The book's firs
Effective quantum field theories
International Nuclear Information System (INIS)
The most appropriate description of particle interactions in the language of quantum field theory depends on the energy at which the interactions are studied; the description is in terms of an ''effective field theory'' that contains explicit reference only to those particles that are actually important at the energy being studied. The various themes of the article are: local quantum field theory, quantum electrodynamics, new physics, dimensional parameters and renormalizability, socio-dynamics of particle theory, spontaneously broken gauge theories, scale dependence, grand unified and effective field theories. 2 figs

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.
Algebraic conformal field theory
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.

The theories on inequality: class theory
Directory of Open Access Journals (Sweden)
Ali Arslan
2006-11-01
Full Text Available This stduy aims to analyse class theory and its major expansions. In addition, the problems and dilemmas of class theory are discussed. Social inequality, either socially or economically, is one of the most common features of capitalist societies. Some people or some social groups have more money, more prestige, more privilege and more influence on the decision making process. Two main strategies have been used for analysing and explaining inequalities. The first and most popular strategy is “class theory” which stresses ownership and control to explain class differentiation. It concentrates on the inequalities based mainly on the ownership or non-ownership of economic resources. Class theory was fathered by Karl Marx and especially developed by Marxist writers. Class analysts focus on identification of classes as the major social forces of society. There are two main schools of thought in class theory with their variations within each school: a Marxist Class Theory, b Weberian Class Theory If the Marxist class analysis and Weberian class analysis are examined it will be seen that, two approaches are incompatible and it is impossible to synthesise them. Nevertheless, Hindess sees Weber’s view as the correction of and supplement to Marx’s ideas rather than an alternative. When the ideas of Marx and Weber are compared, it will be clearly seen that both Marx and Weber explain classes in relation to the economy. Nevertheless, while Marx defines classes in terms of the relations of production, Weber defines them in relation to the market.

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)

This article outlines three ways of analysing the ‘politics of securitization’, emphasizing an often-overlooked form of politics practised through theory design. The structure and nature of a theory can have systematic political implications. Analysis of this ‘politics of securitization’ is distinct from both the study of political practices of securitization and explorations of competing concepts of politics among security theories. It means tracking what kinds of analysis the theory can produce and whether such analysis systematically impacts real-life political struggles. Securitization theory is found to ‘act politically’ through three structural features that systematically shape the political effects of using the theory. The article further discusses – on the basis of the preceding articles in the special issue – three emerging debates around securitization theory: ethics, transformations and post-Western analyses. The article finally suggests one possible way forward for securitization theory: a route built on first clarifying its concept of theory, then specifying more clearly the place of political theory and causal mechanisms in different parts of the analysis. The politics of securitization accordingly becomes sharpened. Instead of deducing the political quality of the theory from various empirical statements by its proponents, this approach zooms in on the very core of the theory: how does it structurally condition work done with it in systematically political ways?

In previous models of (cumulative) prospect theory reference-dependence of preferences is imposed beforehand and the location of the reference point is exogenously determined. This paper provides an axiomatization of a new specification of cumulative prospect theory, termed endogenous prospect theory, where reference-dependence is derived from preference conditions and a unique reference point arises endogenously.

We study theories with 16 supercharges and a discrete energy spectrum. One class of theories has symmetry group SU(2|4). They arise as truncations of N=4 super Yang-Mills theory. They include the plane-wave matrix model, 2+1 super Yang-Mills theory on R×S2 and N=4 super Yang-Mills theory on R×S3/Zk. We explain how to obtain their gravity duals in a unified way. We explore the regions of the geometry that are relevant for the study of some 1/2 BPS and near BPS states. This leads to a class of two dimensional (4,4) supersymmetric sigma models with nonzero H flux, including a massive deformed WZW model. We show how to match some features of the string spectrum with the Yang-Mills theory. The other class of theories are also connected to N=4 super Yang-Mills theory and arise by making some of the transverse scalars compact. Their vacua are characterized by a 2D Yang-Mills theory or 3D Chern-Simons theory. These theories realize peculiar super-Poincaré symmetry algebras in 2+1 or 1+1 dimensions with “noncentral” charges. We finally discuss gravity duals of N=4 super Yang-Mills theory on AdS3×S1.

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.

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

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

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.)

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.
Extended Theories of Gravitation
Directory of Open Access Journals (Sweden)
Fatibene Lorenzo
2013-09-01
Full Text Available Extended theories of gravitation are naturally singled out by an analysis inspired by the Ehelers-Pirani-Schild framework. In this framework the structure of spacetime is described by a Weyl geometry which is enforced by dynamics. Standard General Relativity is just one possible theory within the class of extended theories of gravitation. Also all Palatini f(R theories are shown to be extended theories of gravitation. This more general setting allows a more general interpretation scheme and more general possible couplings between gravity and matter. The definitions and constructions of extended theories will be reviewed. A general interpretation scheme will be considered for extended theories and some examples will be considered.

Boundary S-matrix in a (2,0) theory of AdS_{3} Supergravity
Kaura, Payal
2008-01-01
We will discuss two inequivalent generalizations of the standard $(2,0)$ supergravity action \\cite{Izquierdo:1994jz} to include gravitational Chern-Simons term. One is in the first order formailsm where we treat $\\omega_{M}^{ab}$ as independent and the other is in the second order formalism where $\\omega_{M}^{ab}$ is determined in terms of other fields via a standard constraint equation. Both of them have different equations of motion and the equations of motion of the first order theory spans only a subset of the second order theory. We will be interested in computing the boundary S-matrix in a conformal field theory dual to the supergravity solutions in this sector and hence we use the equations of motion coming out of the first order theory.

OBITUARY: Eur.Ing. Professor David Dew-Hughes in memoriam
Campbell, Archie; Dew-Hughes, Denise; Donaldson, Gordon; Palmer, Richard
2007-06-01
We regret to announce the death of David Dew-Hughes, the second Honorary Editor of Superconductor Science and Technology, in Autumn 2006. He was born in Manchester, the eldest of three children, attended Manchester Grammar School and took his first degree in metallurgy at Birmingham, before undertaking a Doctorate of Engineering at Yale University. After initial work for IBM on semiconductors, he returned to England as a lecturer in metallurgy at Cambridge University. There he devoted his career to superconductivity long before it became fashionable, starting a group on the properties of what we now know as type II materials, with his students Jan Evetts, Archie Campbell and Anant Narlikar. Between them they paved the way to our understanding of the magnetic vortex properties of these materials, and thus to the development of modern practical materials for superconducting magnets. Eur.Ing. Professor David Dew-Hughes 1932-2006 In 1965 he became a founding Senior Lecturer in physics at Lancaster University, moving to Brookhaven National Laboratory in 1974. His final academic post was in engineering science at Oxford University where he also held a University College Tutorial Fellowship. As long ago as 1971 David wrote an authoritative review for Reports on Progress in Physics on 'The metallurgical enhancement of type II superconductors'. Following the discovery of high-Tc superconductivity, IOP Publishing launched Superconductor Science and Technology in 1988 and he was a founder member of its Editorial Board. When Jan Evetts retired as Honorary Editor in 1992, David was the natural choice as his successor. He served a five year term and remained on the Board as Deputy Editor until the end of 2000. To mark the 10th anniversary of high-temperature superconductivity in 1997, David edited a special issue of Superconductor Science and Technology in which past and present members of the Editorial Board contributed reviews of their specialities. He noted that at that time much progress had been made in the study of the chemistry, phase relationships, crystallography, basic physics and materials science of the mixed-oxide systems and the physics of vortices, their configurations, dynamics and interactions with lattice defects. Writing from the perspective of one whose primary interest was in the applications of HTS, he compared the then situation with regard to the development of commercial applications of HTS to the commercial development of low-temperature superconductors. The main commercial application for HTS was yet to be identified, but if the comparison with LTS was accepted, the outlook was hopeful. At the 20th anniversary of high-Tc, now is perhaps a good time for a similar review, but most of David's conclusions still look valid ten years on. The superconductivity community laments his untimely passing and will sorely miss him.
Abstraction Super-structuring Normal Forms: Towards a Theory of Structural Induction
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.

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

QTL for pubertal and seasonality traits in male Père David's x red deer interspecies hybrids.
Goosen, G J; Dodds, K G; Tate, M L; Fennessy, P F
2000-01-01
The unique Pere David's (Elaphurus davidianus) x red deer (Cervus elaphus) backcross hybrid has been used to search for evidence of quantitative trait loci (QTL) for antler pubertal (date and live weight at pedicle initiation) and antler seasonality (date of antler cleaning and casting) traits in temperate species of deer. Analyses using marker information revealed evidence for a QTL for date at pedicle initiation (LOD = 3.7) and live weight at pedicle initiation (LOD = 3.1). These QTL explained 13% and 11% of the phenotypic variance in these traits, respectively. PMID:10994707

The harm of male-on-female rape: a response to David Benatar.
Kelland, Lindsay
2014-10-01
This article attacks David Benatar's claim made in his 2012 book, The Second Sexism: Discrimination Against Men and Boys, that when an individual is the victim of violence it does not matter whether his or her perpetrator is of the same or a different sex. By exploring two related yet distinct phenomena, well documented in the empirical psychological literature, that I call "shattering" and "fragmentation," I argue that when a woman is raped, it does matter that her rapist is male, given that her situation as a woman under patriarchy is partly constitutive of the harm that she suffers.

Serial publication and the emotional associations of words in Dickens' David Copperfield.
Whissell, Cynthia
2006-12-01
A study of the emotional associations and imagery of words in Dickens' serially published novel David Copperfield, quantified by the Dictionary of Affect in Language, identified patterns both in the whole novel and within its chapters and installments. The Pleasantness and Activation of words rose significantly across the novel, while the use of Imagery first fell and then rose again. The last chapter of each installment had shorter sentences and higher scores for Imagery than other chapters, and words within last chapters tended to rise in Pleasantness and Activation within the chapter. It was felt this was likely as a result of Dickens' efforts to maintain dynamism and increase reader interest. PMID:17305192

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

Nonperturbative perturbation theory
International Nuclear Information System (INIS)
A new perturbative computational scheme is proposed for solving self-interacting scalar quantum field theories. To solve a ??4 theory in d-dimensional space-time, a small parameter ? is introduced and a ?(?2)1+? field theory considered. It is shown how to expand such a theory as a series in powers of ?. The resulting perturbation series appears to have a finite radius of convergence and numerical results for low-dimensional models are good. The two-point and four-point Green's functions have been computed to second order in powers of ? and the 2n-point Green's functions (n>2) to order ?. It is explained how to renormalize the theory and the theory is shown to be free to first order in powers of ? when ?>0 and d>=4. This conclusion remains valid to second order in powers of ?, and it is believed that it remains valid to all orders in powers of ?. (author). 7 refs

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

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.)

Free probability theory was created by Dan Voiculescu around 1985, motivated by his efforts to understand special classes of von Neumann algebras. His discovery in 1991 that also random matrices satisfy asymptotically the freeness relation transformed the theory dramatically. Not only did this yield spectacular results about the structure of operator algebras, but it also brought new concepts and tools into the realm of random matrix theory.

This book discusses the most important aspects of the theory. The phenomenological model is followed by the microscopic theory of superconductivity, in which modern formalism of the many-body theory is used to treat most important problems such as superconducting alloys, coexistence of superconductivity with the magnetic order, and superconductivity in quasi-one-dimensional systems. It concludes with a discussion on models for exotic and high temperature superconductivity. Its main aim is to review, as complete as possible, the theory of superconductivity from classical models and methods up t
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)
Games, theory and applications
Thomas, L C
2011-01-01
Anyone with a knowledge of basic mathematics will find this an accessible and informative introduction to game theory. It opens with the theory of two-person zero-sum games, two-person non-zero sum games, and n-person games, at a level between nonmathematical introductory books and technical mathematical game theory books. Succeeding sections focus on a variety of applications - including introductory explanations of gaming and meta games - that offer nonspecialists information about new areas of game theory at a comprehensible level. Numerous exercises appear with full solutions, in addition
Generalized etale cohomology theories
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...

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.

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

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

Three great mathematicians dominate the history of lunar theory in the middle of the eighteenth century: Leonhard Euler, Alexis Clairaut, and Jean le Rond d’Alembert. Each of them made a lasting contribution to the theory of celestial mechanics and their results had a broader impact than on lunar theory alone. To name but a few examples, Euler codified the trigonometric functions and pioneered the method of variation of orbital constants; Clairaut solved the arduous problem of the motion of the lunar apogee, thereby dealing a decisive blow to the sceptics of Newton’s law of gravitation; and d’Alembert worked out an accurate theory of precession and nutation.

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

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.

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

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.

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

A longstanding open problem in lambda calculus is whether there exist continuous models of the untyped lambda calculus whose theory is exactly lambda-beta or the the least sensible lambda-theory H (generated by equating all the unsolvable terms). A related question, raised recently by C. Berline, is whether, given a class of lambda models, there are a minimal lambda-theory and a minimal sensible lambda-theory represented by it. In this paper, we give a positive answer to this question for the...
Covariantizing Classical Field Theories
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.

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
M-Theory and Maximally Supersymmetric Gauge Theories

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

Full Text Available 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.
Corpses of Metaphor. Images of Death in David Leavitt and Jamaica Kincaid
Directory of Open Access Journals (Sweden)

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

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.

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
Rotor theories by Professor Joukowsky: Momentum theories

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.

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

This 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.

Focusing on history of physics, which began about 600 B.C. with the Ionian Greeks and reaching full development within three centuries, suggests that the creation of the concept of the atom is understandable within the context of Greek physical theory; so is the rejection of the atomic theory by the Greek physicists.

Quantum theory. An introduction
International Nuclear Information System (INIS)
The quantum theory is a fundamental component of the physical picture of the world. It yields the framework, in which the objects of the microworld - molecules, atoms, elementary particles - and their interactions can be consistently described. Claus Kiefer introduces the foundations of quantum theory, shows its applications, and discusses its interpretations.

From Helmholtz to Schlick: The evolution of the sign-theory of perception.
Oberdan, Thomas
2015-08-01
Efforts to trace the influence of fin de siècle neo-Kantianism on early 20th Century philosophy of science have led scholars to recognize the powerful influence on Moritz Schlick of Hermann von Helmholtz, the doyen of 19th Century physics and a leader of the zur?ck zu Kant movement. But Michael Friedman thinks that Schlick misunderstood Helmholtz' signature philosophical doctrine, the sign-theory of perception. Indeed, Friedman has argued that Schlick transformed Helmholtz' Kantian view of spatial intuition into an empiricist version of the causal theory of perception. However, it will be argued that, despite the key role the sign-theory played in his epistemology, Schlick thought the Kantianism in Helmholtz' thought was deeply flawed, rendered obsolete by philosophical insights which emerged from recent scientific developments. So even though Schlick embraced the sign-theory, he rejected Helmholtz' ideas about spatial intuition. In fact, like his teacher, Max Planck, Schlick generalized the sign-theory into a form of structural realism. At the same time, Schlick borrowed the method of concept-formation developed by the formalist mathematicians, Moritz Pasch and David Hilbert, and combined it with the conventionalism of Henri Poincaré. Then, to link formally defined concepts with experience, Schlick's introduced his 'method of coincidences', similar to the 'point-coincidences' featured in Einstein's physics. The result was an original scientific philosophy, which owed much to contemporary scientific thinkers, but little to Kant or Kantianism. PMID:26193786
J. J. Sakurai Prize: Harmony of Scattering Amplitudes: From Gauge Theory to Supergravity
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.

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.

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.

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.

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 ...
Nonlocal continuum field theories
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...

Some principal problems of general relativity theory and attempts of their solution are discussed. The Poincare gauge theory of gravity as natural generalization of Einsteinian gravitation theory is considered. The changes of gravitational interaction in the frame of this theory leading to the solution of principal problems of general relativity theory are analyzed.

Intelligence: Pre-Theory and Post-Theory
James R. Flynn
2014-01-01
Defining “intelligence” exemplifies a mistake that has historical precedent: confusing the role of pre-theory and post-theory definitions. In every area, pre-theory concepts give broad directions for investigation: are the movements of heavenly bodies affected by the existence of other heavenly bodies? Post-theory concepts add precision and predictability. The mistake occurs when a successful theory like Newton’s demands that its peculiar and precise theory-imbedded concept forbids competing ...
Reinventing grounded theory: some questions about theory, ground and discovery
Thomas, Gary; James, David
2006-01-01
Grounded theory’s popularity persists after three decades of broad-ranging critique. In this article three problematic notions are discussed—‘theory,’ ‘ground’ and ‘discovery’—which linger in the continuing use and development of grounded theory procedures. It is argued that far from providing the epistemic security promised by grounded theory, these notions—embodied in continuing reinventions of grounded theory—constrain and distort qualitative inquiry, and that what is contrived is not in f...

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

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

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

We study theories with sixteen supercharges and a discrete energy spectrum. One class of theories has symmetry group $SU(2|4)$. They arise as truncations of ${\\cal N}=4$ super Yang Mills. They include the plane wave matrix model, 2+1 super Yang Mills on $R \\times S^2$ and ${\\cal N}=4$ super Yang Mills on $R \\times S^3/Z_k$. We explain how to obtain their gravity duals in a unified way. We explore the regions of the geometry that are relevant for the study of some 1/2 BPS and near BPS states. This leads to a class of two dimensional (4,4) supersymmetric sigma models with non-zero $H$ flux, including a massive deformed WZW model. We show how to match some features of the string spectrum with the Yang Mills theory. The other class of theories are also connected to ${\\cal N}=4$ super Yang Mills and arise by making some of the transverse scalars compact. Their vacua are characterized by a 2d Yang Mills theory or 3d Chern Simons theory. These theories realize peculiar superpoincare symmetry algebras in 2+1 or 1+1 d...
Many body theory and lattice gauge theory
International Nuclear Information System (INIS)
We draw analogies between the shell model and the quark model and also between the many body theory and the lattice gauge theory. We then report results of our lattice calculations on the ?N ? term and the flavor-singlet axial charge of the nucleon in the framework of quenched QCD. The disconnected insertions, or vacuum polarizations, which involve contributions from the sea quarks are evaluated with the stochastic estimator with the Z2 noise which yields minimum variances. We find the sea-quark contribution to the ?N ? term to be similar [1]/[2]-[1]/[4] of that of the dynamical fermion calculation. Whereas the sea-quark contribution to the flavor-singlet gA is negative and large enough to cancel the valence (connected insertion) contribution substantially to resolve the ''proton spin crisis''.

Full Text Available The aim of this paper is to make a scientific contribution for a better understanding of the relationship between the Prospect Theory and SERVQUAL. The first objective is to analyse whether the SERVQUAL scale is an appropriate scale to quantify service quality and customer satisfaction of automobile-insurances. The second objective is to discuss the relationship between service quality and customer satisfaction. With the prospect theory, the relationship is explained and described. Only a negative asymmetric relationship between service quality and customer satisfaction can be explained by the prospect theory. The proposed diminishing sensitivity lacks sufficient significant empirical evidence.

This book explains many fundamental ideas on the theory of distributions. The theory of partial differential equations is one of the synthetic branches of analysis that combines ideas and methods from different fields of mathematics, ranging from functional analysis and harmonic analysis to differential geometry and topology. This presents specific difficulties to those studying this field. This book, which consists of 10 chapters, is suitable for upper undergraduate/graduate students and mathematicians seeking an accessible introduction to some aspects of the theory of distributions. It can also be used for one-semester course.

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

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

In this work, the relationship between splines and the control theory has been analyzed. We show that spline functions can be constructed naturally from the control theory. By establishing a framework based on control theory, we provide a simple and systematic way to construct splines. We have constructed the traditional spline functions including the polynomial splines and the classical exponential spline. We have also discovered some new spline functions such as trigonometric splines and the combination of polynomial, exponential and trigonometric splines. The method proposed in this paper is easy to implement. Some numerical experiments are performed to investigate properties of different spline approximations.

Gauge theories are studied on a space of functions with the Moyal-Weyl product. The development of these ideas follows the differential geometry of the usual gauge theories, but several changes are forced upon us. The Leibniz rule has to be changed such that the theory is now based on a twisted Hopf algebra. Nevertheless, this twisted symmetry structure leads to conservation laws. The symmetry has to be extended from Lie algebra valued to enveloping algebra valued and new vector potentials have to be introduced. As usual, field equations are subjected to consistency conditions that restrict the possible models. Some examples are studied.
