“Farrington, David P.: The Integrated Cognitive Antisocial Potential Theory”  

OpenAIRE

The aim of this paper is to describe the theoretical principles and the empirical development of the Integrated Cognitive Antisocial Potential (ICAP) Theory. The ICAP theory reflects the findings of the major longitudinal studies in the Western world, and especially those of the Cambridge Study in Development Delinquency (CSDD), which is a prospective longitudinal study of 411 South-London males from age 8 to age 48. The ICAP theory is intended to address offending.

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

Directory of Open Access Journals (Sweden)

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.

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

Science.gov (United States)

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

A Philosophical Analysis of David Orr's Theory of Ecological Literacy: Biophilia, Ecojustice and Moral Education in School Learning Communities  

Science.gov (United States)

In his writings, David Orr claims that the US is in an "ecological crisis" and that this stems from a crisis of education. He outlines a theory of ecological literacy, a mode by which we better learn the ecology of the Earth and live in a sustainable manner. While emphasizing a shock doctrine, the diagnosis of "crisis" may be correct, but it is…

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

CERN Document Server

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

Integral Evolution: An Interview with David Loye  

Directory of Open Access Journals (Sweden)

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

In the middle of the 1980s, David Poole introduced a semantical, model-theoretic notion of specificity to the artificial-intelligence community. Since then it has found further applications in non-monotonic reasoning, in particular in defeasible reasoning. Poole tried to approximate the intuitive human concept of specificity, which seems to be essential for reasoning in everyday life with its partial and inconsistent information. His notion, however, turns out to be intricat...

David Warner (1934 - 2003)  

CERN Multimedia

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 Hauntology  

DEFF Research Database (Denmark)

David Bowie's now-defunct rock-opera trilogy's first installment 1. Outside is filled with uncanny mediations of rock music's chameleon. The inner sleeve booklet is titled The Diary of Nathan Adler, or the Ritual Art-Murder of Baby Grace Blue: A non-linear Gothic Drama Hyper-Cycle. Behind this long-winded title, is the story of a murder, narrated by several characters through both text, music and images. Bowie, however, is the narrator of all these different voices, using technology to distort his voice into these different characters as separate entities. His voice and presence haunts the entire album in uncanny forms, just as all images in the booklet are distorted images of Bowie himself, made into uncanny doubles. The story begins with the murder of Baby Grace Blue, who is enacted by Bowie himself. Symbolically, Bowie is murdered by himself, while Baby Grace haunts the entire album's Gothic and labyrinthine structure. My paper will focus on the mediated double of David Bowie, his ventriloquist voiceand simulacral presence as character, creator and ghost. I will problematize the notion of an outside to the album, focussing on what can be termed the album's hauntological status.

Paranoid, moi? : Erasing David  

DEFF Research Database (Denmark)

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

David’s flight from Jerusalem according to Josephus  

Directory of Open Access Journals (Sweden)

Full Text Available 2 Samuel 15:13-16:14 tells of David’s flight from Jerusalem to the Jordan in the face of his son Absalom’s rebellion and of the five encounters that occur during that journey. This article focuses on Josephus’ retelling of the episode in his Ant 7.198-210. The article’s detailed comparison between the Samuel passage and its Josephan version aims to find answers to such questions as: Which of 2 Samuel 15:13-16:14 text-forms(s did Josephus utilize? What rewriting techniques has he applied to the data of his source and what is distinctive about his own resultant rendering? Finally, how does Josephus’ handling of the Scriptural data in this case compare with how the data is treated elsewhere in early Jewish and Christian tradition?

David Liberman's legacy.  

Science.gov (United States)

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

Science.gov (United States)

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

David Irving: Britain's Holocaust "Revisionist"  

Science.gov (United States)

Released in Mark 2000 by the Israeli State Archives, the memoirs of Adolf Eichmann offer a chilling, though self-serving, account of the workings of the Nazi's "Final Solution." Although most scholars dismiss the diary as an attempt by Eichmann to defend or exonerate himself while on trial for his central role in the Holocaust, the manuscript was still sealed in the Israeli archives for 39 years. It was made public at the request of Deborah Lipstadt, a professor at Emory University, who, along with her publisher, Penguin Books, is being sued for libel by David Irving, a British historian whom Lipstadt characterized as a "dangerous spokesman" for Holocaust denial. Under Britain's libel laws, the burden of proof is on the defendant, which means that Lipstadt must discredit Irving's position by demonstrating that he has willfully ignored or distorted the facts. Due to the complicated nature of the trial, it has been heard without a jury, and closing arguments are scheduled for March 13. The Nizkor Project, one of the largest online repositories of primary documents related to the Holocaust, is dedicated to combatting Holocaust denial and has made available the full text of the diary, False Gods, (in German only) in .txt, .rtf, and MS Word formats. Users can also learn more about David Irving at Nizkor's special section on him. The page includes numerous related documents and links to press updates from the libel trial.

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

Scientific Electronic Library Online (English)

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

A series of important papers by David Turnbull and his collaborators in the late 1940's and early 1950's laid the experimental and theoretical foundation of modern nucleation theory. The elegance, versatility, and generality of the phenomenological approach, coupled with brilliant and insightful experimental confirmation, sparked widespread application which continues today. Much of David Turnbull's subsequent work in other subjects grew directly or indirectly from this work

Physics Nobel prize 2004: Surprising theory wins physics Nobel  

CERN Multimedia

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

Henry David Thoreau: Literary Transcendentalism  

Directory of Open Access Journals (Sweden)

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

Rainforest pioneer. Millennium trailblazers 3: David Cassell.  

Science.gov (United States)

The Iwokrama International Centre for Rain Forest Conservation in Guyana is headed by Australian forester David Cassells who is also chairman of the Advisory Group for the World Conservation Union Forest Conservation Program. He states that this program is different from other projects to conserve tropical forests since it focuses on financial sustainability and self-sufficiency. 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

David Lasser - An American Spaceflight Pioneer  

Science.gov (United States)

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

David Lukens Reasoner (1941-1992)  

Science.gov (United States)

David Lukens Reasoner, former head of NASA's Ionospheric Physics branch, died on April 21, 1992. Reasoner was born July 1, 1941. He worked tirelessly to expand NASA's Space Physics Division, bringing his deep experience and personal expertise to bear on the challenges of growth.During the magical period of the late 1950s and early 1960s when America turned its eyes toward space and the Moon, David Lukens Reasoner journeyed north from the nearby Texas town of Dickinson to Rice University with an idea of getting involved in exploring the frontiers of space. He pursued a course of study in electrical engineering and received a bachelor's degree in 1963 and a master's degree in 1964. In the early 1960s, the Space Science Department at Rice was formed, and President John Kennedy visited to say that America chose to go to space not because it is easy but because it is hard and because it would require the very best talents of our nation to succeed. Dave Reasoner was one of those talented people. His excellence in electrical engineering and physics, combined with his natural abilities in the laboratory, suited him ideally for building the machines of space. As a student, he built sounding rocket payloads and multiple instruments for satellites and experiment packages that were placed on the Moon by the Apollo astronauts. He completed his doctoral degree in space science in 1968. It was in these early thrilling days of space exploration that I first met Dave, beginning a friendship and collegial relationship that was to last 27 years.

Waltz's Theory of Theory  

DEFF Research Database (Denmark)

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

Obituary: David L. Band (1957-2009)  

Science.gov (United States)

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

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

Directory of Open Access Journals (Sweden)

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

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

Capacity theory on algebraic curves  

CERN Document Server

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

David Barker: the revolution that anticipates existence  

Directory of Open Access Journals (Sweden)

Full Text Available David Barker is the man who “anticipated" the existence of babies by focusing attention on the importance of the fetus and what takes place during intrauterine life. Barker was one of the physicians who in the last decades brought about the greatest changes in medicine, changes so important as to represent a veritable revolution in medical thought. According to Barker's studies, the embryo obviously has a genetic complement coming from the mother and father, but from the very first stages of development it begins to undergo the influence of the outside environment, just as occurs for adults whose biological, psychological and pathological aspects are influenced by the environment to a not well-established percentage between genetic complement and epigenetics. Much of our future lives as adults is decided in our mothers' wombs. If Barker's discovery was revolutionary from the cultural standpoint, it was even more so from the strictly medical one. Barker's research method was rigid from the methodological standpoint, but innovative and speculative in its working hypotheses, with a humanistic slant. Barker's idea has another practical corollary: it is evident that the role of obstetricians, perinatologists and neonatologists is more and more relevant in medicine and future prevention. Unquestionably, besides the enormous merits of his clinical research, among the benefits that Barker has contributed there is that of having helped us to see things from new points of view. Not only is the neonate (and even more so the fetus not an adult of reduced proportions, but perhaps the neonate is the "father" of the adult person.

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

Computability theory  

OpenAIRE

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...

David, who from September 1971 to February 1984 actively lived his life in a sterile isolator, was severely deprived of experience of the physical world. His difficulty with the concepts of space, depth, and size related clearly to his limited experience rather than to cognitive or visual-motor-perceptual deficits. (Author/CL)

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

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

Directory of Open Access Journals (Sweden)

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

Supergravity theories  

International Nuclear Information System (INIS)

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

Superstring theory  

International Nuclear Information System (INIS)

The current status of cosmological string theory is briefly surveyed. The principles of the standard model of quantum gravity are reviewed; proposed modifications of the model are discussed; and it is shown how the basic assumption of string theory, that particles are one-dimensional objects rather than dimensionless points, leads to requirements for gravity, supersymmetry, extra dimensions, gauge groups and matter multiplets, and an axion. The existence of a minimum distance in string theory is considered, along with the related possibility of a maximum scalar field value. It is also shown that string theory can provide both the technology and interpretation for experiments on topology change in quantum gravity. 27 refs

Uncertainty theory  

CERN Document Server

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

The Greening of the David L. Lawrence Pittsburgh Convention Center  

Science.gov (United States)

The David L. Lawrence Convention Center is the largest Gold LEED NC (new construction) certified convention center in the USA and the first of its kind in the world. The designation has been awarded by the United States Green Building Council through its Leadership in Energy and Environmental Design (LEED) Green Building Rating System. In this talk we discuss the unique green properties of this 1.5 million square foot Convention Center including the design and use of daylight, natural ventilation and other sustainable design and practices. No other building the size of the Convention Center (1.5 million square feet), uses natural ventilation or can illuminate an exhibition hall entirely through its windows and skylights. Approximately 75% of the convention center's exhibition space is lit by natural daylight. The use of natural ventilation and extensive day lighting is designed to reduce energy consumption by nearly 35% compared to traditional ventilated and lit buildings of a similar size.

Toxinotyping of Clostridium perfringens fecal isolates of reintroduced Père David's deer (Elaphurus davidianus) in China.  

Science.gov (United States)

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

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

Directory of Open Access Journals (Sweden)

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].

Is Mass Society a Threat to Representative Democracy? Revisiting David Riesman’s “Other-Directed Character”  

Directory of Open Access Journals (Sweden)

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.

Einstein's Theory Fights off Challengers  

Science.gov (United States)

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

Bohmian Mechanics The Physics and Mathematics of Quantum Theory  

CERN Document Server

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

Scattering theory  

Energy Technology Data Exchange (ETDEWEB)

Written by the author of the widely acclaimed textbook. Theoretical Atomic Physics Includes sections on quantum reflection, tunable Feshbach resonances and Efimov states. Useful for advanced students and researchers. This book presents a concise and modern coverage of scattering theory. It is motivated by the fact that experimental advances have shifted and broadened the scope of applications where concepts from scattering theory are used, e.g. to the field of ultracold atoms and molecules, which has been experiencing enormous growth in recent years, largely triggered by the successful realization of Bose-Einstein condensates of dilute atomic gases in 1995. In the present treatment, special attention is given to the role played by the long-range behaviour of the projectile-target interaction, and a theory is developed, which is well suited to describe near-threshold bound and continuum states in realistic binary systems such as diatomic molecules or molecular ions. The level of abstraction is kept as low as at all possible, and deeper questions related to mathematical foundations of scattering theory are passed by. The book should be understandable for anyone with a basic knowledge of nonrelativistic quantum mechanics. It is intended for advanced students and researchers, and it is hoped that it will be useful for theorists and experimentalists alike.

Matching theory  

CERN Document Server

This study of matching theory deals with bipartite matching, network flows, and presents fundamental results for the non-bipartite case. It goes on to study elementary bipartite graphs and elementary graphs in general. Further discussed are 2-matchings, general matching problems as linear programs, the Edmonds Matching Algorithm (and other algorithmic approaches), f-factors and vertex packing.

Cosmology: theory  

CERN Document Server

The discovery of 126 GeV Higgs boson and observations of no signs of new physics at the LHC implies that the Standard Model of elementary particles is a self-consistent weakly-coupled effective field theory all the way up to the Planck scale without the addition of any new particles. I will discuss possible consequences of these findings for cosmology.

String Theory  

Science.gov (United States)

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.

Transatlantic Miscommunication in David Hare’s Drama Stuff Happens  

Directory of Open Access Journals (Sweden)

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.

Characterization Report for the David Witherspoon Screen Art Site  

Energy Technology Data Exchange (ETDEWEB)

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

Reconstructing apology: David Cameron's Bloody Sunday apology in the press.  

Science.gov (United States)

While there is an acknowledgement in apology research that political apologies are highly mediated, the process of mediation itself has lacked scrutiny. This article suggests that the idea of reconstruction helps to understand how apologies are mediated and evaluated. David Cameron's apology for Bloody Sunday is examined to see how he constructs four aspects of apology: social actors, consequences, categorization, and reasons. The reconstruction of those aspects by British, Unionist, and Nationalist press along with reconstructions made by soldiers in an online forum are considered. Data analysis was informed by thematic analysis and discourse analysis which helped to explore key aspects of reconstruction and how elements of Cameron's apology are altered in subsequent mediated forms of the apology. These mediated reconstructions of the apology allowed their authors to evaluate the apology in different ways. Thus, in this article, it is suggested that the evaluation of the apology by different groups is preceded by a reconstruction of it in accordance with rhetorical goals. This illuminates the process of mediation and helps to understand divergent responses to political apologies. PMID:24286526

Space craft verification at the David Florida Laboratory  

Science.gov (United States)

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

David Florida Laboratory: Support for mobile satellite communications  

Science.gov (United States)

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

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

Directory of Open Access Journals (Sweden)

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.

Gauge theories  

International Nuclear Information System (INIS)

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

Communication theory  

DEFF Research Database (Denmark)

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).

Potential theory  

CERN Document Server

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

Activity Theory  

DEFF Research Database (Denmark)

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

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

Directory of Open Access Journals (Sweden)

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

String theory dualities from M theory

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.

Field theory questions for string theory answers  

International Nuclear Information System (INIS)

We discuss the field theory of 3-brane probes in F-theory compactifications in two configurations, generalizing the work of Sen and of Banks, Douglas and Seiberg. One configuration involves several parallel 3-brane probes in F-theory compactified on T4/Z2, while the other involves a compactification of F-theory on T6/Z2 x Z2 (which includes intersecting D4 singularities). In both cases string theory provides simple pictures of the space-time theory, whose implications for the 3-brane world-volume theories are discussed. In the second case the field theory on the probe is an unusual N=1 superconformal theory, with exact electric-magnetic duality. Several open questions remain concerning the description of this theory. (orig.)

Sustainablegrowth theories  

International Nuclear Information System (INIS)

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

Cluster-like coordinates in supersymmetric quantum field theory.  

Science.gov (United States)

Recently it has become apparent that N = 2 supersymmetric quantum field theory has something to do with cluster algebras. I review one aspect of the connection: supersymmetric quantum field theories have associated hyperkähler moduli spaces, and these moduli spaces carry a structure that looks like an extension of the notion of cluster variety. In particular, one encounters the usual variables and mutations of the cluster story, along with more exotic extra variables and generalized mutations. I focus on a class of examples where the underlying cluster varieties are moduli spaces of flat connections on surfaces, as considered by Fock and Goncharov [Fock V, Goncharov A (2006) Publ Math Inst Hautes Études Sci 103:1-211]. The work reviewed here is largely joint with Davide Gaiotto and Greg Moore. PMID:24982190

THEORIES OF CORPORATE GOVERNANCE  

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

Full Text Available Taking Anne Friedberg's notion of the post-perspectival as the point of departure for her analysis of David Lynch's digitally shot and edited Inland Empire from 2006, Anne Jerslev argues that the film deconstructs continuous time and coherent space by constructing multiple planes of representation, multiple layerings of screens and, hence, multiple and fractured modes of perception. The article further suggests that the film's enigmatic structure might best be understood with reference to a new media genre like the website with its hyperlink structure. Finally, the article discusses how a sense of ubiquitous surveillance coalesces with the screen logic.Author Biography Anne Jerslev (PhD is Professor of Film and Media Studies at the Department of Media, Cognition and Communication, University of Copenhagen.

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

Directory of Open Access Journals (Sweden)

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

Simple modification of "T. David-V" valve-sparing aortic root replacement to create graft pseudosinuses.  

Science.gov (United States)

The absence of sinuses of Valsalva is postulated to perturb coronary flow patterns and to create abnormal leaflet stresses, which theoretically may limit the long-term durability of valve-sparing aortic root replacement with the original Tirone David-I reimplantation technique with a cylindrical tube graft. David developed the "T. David-V" procedure in 2001; it creates large billowing Dacron pseudosinuses while retaining the reimplantation concept. To illustrate a simple modification of the T. David-V technique, we describe a patient with Marfan's syndrome who underwent valve-sparing aortic root replacement with 1 large and 1 small graft to create pseudosinuses in the Dacron graft, to facilitate suturing the valve inside the graft, and to make the distal graft-to-aorta anastomosis a better size match.

A foundation is laid for future analyses of gravitation theories. This foundation is applicable to any theory formulated in terms of geometric objects defined on a 4-dimensional spacetime manifold. The foundation consists of (1) a glossary of fundamental concepts; (2) a theorem that delineates the overlap between Lagrangian-based theories and metric theories; (3) a conjecture (due to Schiff) that the Weak Equivalence Principle implies the Einstein Equivalence Principle; and (4) a plausibility argument supporting this conjecture for the special case of relativistic, Lagrangian-based theories.

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

Directory of Open Access Journals (Sweden)

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/.

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

Scientific Electronic Library Online (English)

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

Polite Theories Revisited  

Science.gov (United States)

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

The availability of an accurate digital representation opens several possibilities of utilization to experts (restorers, archivists, museum curators), or to ordinary people (students, museum visitors). 3D scanned data are commonly used for the production of animations, interactive visualizations, or virtual reality applications. A much more exciting opportunity is to use these data in the restoration of Cultural Heritage artworks. The integration between 3D graphic and restoration represents an open research field where many new supporting tools are required; the David restoration project has given several starting points and guidelines to the definition and development of innovative solutions. Digital 3D models can be used in two different but not subsidiary modes: as an instrument for the execution of specific investigations and as a supporting media for the archival and integration of all the restoration-related information, gathered with the different studies and analysis performed on the artwork. In this paper we present some recent work done in the framework of the Michelangelo's David restoration project. A 3D model of the David was reconstructed by the Digital Michelangelo Project, using laser-based 3D scanning technology. We have developed some tools to make those data accessible and useful in the restoration. Preliminary results are reported here together with some directions for further research.

Automatic theory formation in graph theory  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english This paper presents SCOT, a system for automatic theory construction in the domain of Graph Theory. Following on the footsteps of the programs ARE [9], HR [1] and Cyrano [6], concept discovery is modeled as search in a concept space. We propose a classification for discovery heuristics, which takes [...] into account the main processes related to theory construction: concept construction, example production, example analysis, conjecture construction, and conjecture analysis.

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.

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

Directory of Open Access Journals (Sweden)

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

Neo-newtonian theories  

CERN Document Server

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.

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

Scientific Electronic Library Online (English)

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

Theories of analytic monads  

CERN Document Server

We characterize the equational theories and Lawvere theories that correspond to the categories of analytic and polynomial monads on Set, and hence also the categories of the symmetric and rigid operads in Set. We show that the category of analytic monads is equivalent to the category of regular-linear theories. The category of polynomial monads is equivalent to the category of rigid theories, i.e. regular-linear theories satisfying an additional global condition. This solves a problem A. Carboni and P. T. Johnstone. The Lawvere theories corresponding to these monads are identified via some factorization systems.

We give an introduction to massive spin-2 theories (including massive gravity) and the problem of their non-linear completion. We review the Boulware-Deser ghost problem and two ways to circumvent classic no-go theorems. In turn, massive spin-2 theories are not uniquely defined. In the case of truncated theories, we show that the Boulware-Deser ghost may only be avoided if the derivative structure of the theory is not tuned to be Einsteinian.

Consequently, a multi-determinant presentation of the wave function of the system of weak...

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)

Noncommutative Gauge Theories: Model for Hodge Theory

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

Noncommutative Induced Gauge Theory  

CERN Document Server

We consider an external gauge potential minimally coupled to a renormalisable scalar theory on 4-dimensional Moyal space and compute in position space the one-loop Yang-Mills-type effective theory generated from the integration over the scalar field. We find that the gauge invariant effective action involves, beyond the expected noncommutative version of the pure Yang-Mills action, additional terms that may be interpreted as the gauge theory counterpart of the harmonic oscillator term, which for the noncommutative $\\phi^4$-theory on Moyal space ensures renormalisability. The expression of a possible candidate for a renormalisable action for a gauge theory defined on Moyal space is conjectured and discussed.

f(R Theories  

Directory of Open Access Journals (Sweden)

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

Nuclear structure theory  

CERN Document Server

Nuclear Structure Theory provides a guide to nuclear structure theory. The book is comprised of 23 chapters that are organized into four parts; each part covers an aspect of nuclear structure theory. In the first part, the text discusses the experimentally observed phenomena, which nuclear structure theories need to look into and detail the information that supports those theories. The second part of the book deals with the phenomenological nucleon-nucleon potentials derived from phase shift analysis of nucleon-nucleon scattering. Part III talks about the phenomenological parameters used to de

Model theory and modules  

CERN Document Server

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

Measure and integration theory  

CERN Document Server

This book gives a straightforward introduction to the field as it is nowadays required in many branches of analysis and especially in probability theory. The first three chapters (Measure Theory, Integration Theory, Product Measures) basically follow the clear and approved exposition given in the author's earlier book on ""Probability Theory and Measure Theory"". Special emphasis is laid on a complete discussion of the transformation of measures and integration with respect to the product measure, convergence theorems, parameter depending integrals, as well as the Radon-Nikodym theorem.

Free Field Theory as a String Theory?  

OpenAIRE

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

Design Theory Projectability  

DEFF Research Database (Denmark)

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.

The practicality of theory.  

Science.gov (United States)

The study of medical education has broadened significantly over the past decade to include a wide variety of theoretical frameworks from multiple research domains. There remains a significant misconception, however, that learning theories (largely drawn from cognitive psychology and education) are practical and useful to educators, whereas other types of theory are not. The authors of this commentary reflect on a learning-theory-based model for developing master learners presented by Schumacher and colleagues in this issue of Academic Medicine. They suggest that bioscientific and sociocultural theories can enhance different aspects of that model and provide specific examples from neuropsychophysiology, Foucauldian discourse analysis, and critical theory. Bioscientific and sociocultural theories such as these present medical educators with an exciting array of new methodological and interpretive possibilities. The authors illustrate ways in which these theories can have important practical applications for, and impacts on, the practice of medical education. PMID:24072104

Testing metabolic theories.  

Science.gov (United States)

Metabolism is the process by which individual organisms acquire energy and materials from their environment and use them for maintenance, differentiation, growth, and reproduction. There has been a recent push to build an individual-based metabolic underpinning into ecological theory-that is, a metabolic theory of ecology. However, the two main theories of individual metabolism that have been applied in ecology-Kooijman's dynamic energy budget (DEB) theory and the West, Brown, and Enquist (WBE) theory-have fundamentally different assumptions. Surprisingly, the core assumptions of these two theories have not been rigorously compared from an empirical perspective. Before we can build an understanding of ecology on the basis of individual metabolism, we must resolve the differences between these theories and thus set the appropriate foundation. Here we compare the DEB and WBE theories in detail as applied to ontogenetic growth and metabolic scaling, from which we identify circumstances where their predictions diverge most strongly. Promising experimental areas include manipulative studies of tissue regeneration, body shape, body condition, temperature, and oxygen. Much empirical work designed specifically with DEB and WBE theory in mind is required before any consensus can be reached on the appropriate theoretical basis for a metabolic theory of ecology.

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

Directory of Open Access Journals (Sweden)

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.

Sulle orme di Racine e Metastasio: Il castigo di Atalia di David Franco-Mendes  

Directory of Open Access Journals (Sweden)

Full Text Available Atalia's Punishment by David Franco-Mendes is a biblical drama which belongs to the period of the  Hebrew Haskalah. The author declares openly that he was inspired by the works of Racine and Metastasio,  but although it is possible to identify many common features, there are also important differences. The character of Atalia is deprived of a tragic stature which could inspire sympathy in the reader,  while all the elements of the text regarding the Temple of Jerusalem and the coronation of the legitimate  heir to the lineage of David are amplified. In this way, the drama, as compared to the works of Racine  and Metastasio, is brought back to be closer to the sensibility of a Jewish audience. Its being written  according to the canons of modern literature, and in pure Biblical Hebrew, however, makes it ideally  accessible to an educated audience of non-Jewish origin. The work can then be interpreted as an attempt  to mediate between the Jewish and non-Jewish European culture, in the spirit of the Haskalah.

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

Science.gov (United States)

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

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.

String theory meets QCD  

International Nuclear Information System (INIS)

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

F-theory Superspace  

CERN Document Server

We consider, at the linearized level, the superspace formulation of lower-dimensional F-theory. In particular, we describe the embedding of 3D Type II supergravity of the superstring, or 4D, N=1 supergravity of M-theory, into the corresponding F-theory in full detail, giving the linearized action and gauge transformations in terms of the prepotential. This manifestly supersymmetric formulation reveals some features not evident from a component treatment, such as Weyl and local S-supersymmetry invariances. The linearized multiplet appears as a super 3-form (just as that for the manifestly T-dual theory is a super 2-form), reflecting the embedding of M-theory (as the T-dual theory embeds Type II supergravity). We also give the embedding of matter multiplets into this superspace, and derive the F-constraint from the gauge invariance of the gauge invariance.

Geometric Theory of Defects  

CERN Document Server

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

Is string theory true?  

International Nuclear Information System (INIS)

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

A similar procedure applied to Donaldson-Uhlenbeck-Yau instantons on $\\bC^3$, viewed as intersecting membranes of 7D supersymmetric Yang-Mills (SYM) theory, yields (for finite boost) a new set of 1/4 BPS equations for 6D SYM-Higgs theory, and (for infinite boost) a generalization of the dyonic instanton equations of 5D SYM-Higgs theory, solutions of which are interpreted as Yang-Mills supertubes and realized as configurations of IIB string theory.

Variational transition state theory  

Energy Technology Data Exchange (ETDEWEB)

In recent years our research group has made a systematic effort to study the validity of transition state theory (TST). We have found that the conventional theory is sometimes remarkably accurate, but in many other cases it leads to large errors. Fortunately we have found that a much more reliable theory that has many of the advantages of conventional TST can also be formulated, and it can be applied to practical problems with an effort that is much closer to that required for conventional transition state theory than to that required for quantal dynamics calculations. The two most important features in the improved approach to transition state theory state theory are the variational determination of the transition state and the incorporation of tunneling contributions by multidimensional semiclassical approximations. 13 refs.

Differential Galois theory has played important roles in the theory of integrability of linear differential equation. In this paper we will extend the theory to nonlinear case and study the integrability of the first order nonlinear differential equation. We will define for the differential equation the differential Galois group, will study the structure of the group, and will prove the equivalent between the existence of the Liouvillian first integral and the solvability of...

The game theory techniques are used to find the equilibrium of a market. Game theory refers to the ways in which strategic interactions among economic agents produce outcomes with respect to the preferences (or utilities) of those agents, where the outcomes in question might have been intended by none of the agents. The oligopolistic market structures are taken and how game theory applies to them is explained.

The theory of flotation  

Science.gov (United States)

A brief summary of the fundamentals of the Linear theory of flotation is given. The theory by no means contradicts the previous Laminar theory or even the thermodynamics (Wark-Siedler), rather it is a refinement of the known Hardy-Langmuir-Harkin conceptions for the case when there are not two phases and phase boundaries, but rather three phases and corresponding phase boundary edges. The appearance of such three-phase boundaries (ore, water, air) is characteristic for modern flotation methods.

Chiral perturbation theory  

International Nuclear Information System (INIS)

Applications include the light quark mass ratios and pion-pion scattering to two-loop accuracy. In the pion-nucleon system, the linear ? model is contrasted with chiral perturbation theory. The heavy-nucleon expansion is used to construct the effective pion-nucleon Lagrangian to third order in the low-energy expansion, with applications to nucleon Compton scattering. (author)

Effective field theories

Effective field theories encode the predictions of a quantum field theory at low energy. The effective theory has a fairly low ultraviolet cutoff.

Methods will be discussed how to compute an effective low energy action from a given fundamental action, either analytically or n...

The Tensor Theory Space

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

Class field theory from theory to practice  

CERN Document Server

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

Kaluza--Klein theory  

International Nuclear Information System (INIS)

Assuming the compactification of 4+K-dimensional space-time implied in Kaluza--Klein-type theories, we consider the case in which the internal manifold is a quotient space, G/H. We develop normal mode expansions on the internal manifold and show that the conventional gravitational plus Yang-Mills theory (realizing local G symmetry) is obtained in the leading approximation. The higher terms in the expansions give rise to field theories of massive particles. In particular, for the original Kaluza--Klein 4+1-dimensional theory, the higher excitations describe massive, charged, purely spin-2 particles. These belong to infinite dimensional representations of an O

Covariantizing Classical Field Theories  

CERN Document Server

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.

Stationary scattering theory  

International Nuclear Information System (INIS)

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

CERN Document Server

Free probability theory was created by Dan Voiculescu around 1985, motivated by his efforts to understand special classes of von Neumann algebras.

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. In the following we will give, mostly from the random matrix point of view, a survey on some of the basic ideas and results of free probability theory.

Portfolio Theory Forward Testing  

Directory of Open Access Journals (Sweden)

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

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

Pavlov's conceptualization of the dynamic stereotype in the theory of higher nervous activity.  

Science.gov (United States)

David Joravsky (1989) alleges that Ivan Petrovich Pavlov's theory of higher nervous activity fails to explain "most forms of complex behavior" because establishment of second-order and third-order chains of conditional reflexes was not feasible. Yet, Pavlov (1951a), relying on experimental evidence, some of which is presented, held that the interaction of higher organisms with the external environment was based on the dynamic stereotype, that is, on the integration in the cortical hemispheres of neural traces coming from the external and internal environments. In its formulation in the 1930s, Pavlov's theory was dynamic, not associative. It postulated the synthesis of conditioned reflexes, not associative chains of conditioned reflexes. PMID:8644888

Scaling violation in a field theory of closed strings in one physical dimension  

International Nuclear Information System (INIS)

A one dimensional field theory of closed strings is solved exactly in a special double scaling limit, in which the string coupling 1/N goes to zero, the cosmological constant ? approaches a critical value ?c (corresponding to the limit of an infinitely large world sheet), and some nontrivial scaling parameter ?(?c-?, N) is fixed. The structure of singularities of the string susceptibility ?(?, N) is analyzed, order by order in the topological (1/N) expansion, as well as nonperturbatively, for arbitrary ?. It is shown that the 'naive' scaling, which confirmed the work of Polyakov, Knizhnik and Zamolodchikov, of David, and of Distler and Kawai when the central charge is smaller than one, is violated by logarithmic corrections at every order of the topological expansion. Nonperturbative effects in 1/N arise through vacuum instabilities of this string field theory for any finite ?. (orig.)

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

Directory of Open Access Journals (Sweden)

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

Evaluating Conceptual Metaphor Theory  

Science.gov (United States)

A major revolution in the study of metaphor occurred 30 years ago with the introduction of "conceptual metaphor theory" (CMT). Unlike previous theories of metaphor and metaphorical meaning, CMT proposed that metaphor is not just an aspect of language, but a fundamental part of human thought. Indeed, most metaphorical language arises from…

Local symplectic field theory  

OpenAIRE

Generalizing local Gromov-Witten theory, in this paper we define a local version of symplectic field theory. When the symplectic manifold with cylindrical ends is four-dimensional and the underlying simple curve is regular by automatic transversality, we establish a transversality result for all its multiple covers and discuss the resulting algebraic structures.

Rewriting the Opportunity Theory  

DEFF Research Database (Denmark)

The aim of this paper is to further the discussion of opportunity theory by discussing its ontological and epistemological underpinnings, which have been neglected in previous discussions. The idea that opportunities have an objective component is critically examined drawing on insights from social constructionism. It is argued that opportunity theory needs to be rewritten.

Why Bohm's Quantum Theory?  

OpenAIRE

This is a brief reply to Goldstein's article on ``Quantum Theory Without Observers'' in Physics Today. It is pointed out that Bohm's pilot wave theory is successful only because it keeps Schr\\"odinger's (exact) wave mechanics unchanged, while the rest of it is observationally meaningless and solely based on classical prejudice.

Noncommutative induced gauge theory  

Energy Technology Data Exchange (ETDEWEB)

We consider an external gauge potential minimally coupled to a renormalisable scalar theory on 4-dimensional Moyal space and compute in position space the one-loop Yang-Mills-type effective theory generated from the integration over the scalar field. We find that the gauge-invariant effective action involves, beyond the expected noncommutative version of the pure Yang-Mills action, additional terms that may be interpreted as the gauge theory counterpart of the harmonic oscillator term, which for the noncommutative {phi}{sup 4}-theory on Moyal space ensures renormalisability. The expression of a possible candidate for a renormalisable action for a gauge theory defined on Moyal space is conjectured and discussed. (orig.)

Extended Theories of Gravity  

CERN Document Server

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

Statistical theory and inference  

CERN Document Server

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

Lattice Gerbe Theory  

CERN Document Server

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.

Toward classifying unstable theories  

CERN Document Server

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

Polyhedral adjunction theory  

CERN Document Server

In this paper we give a combinatorial view on the adjunction theory of toric varieties. Inspired by classical adjunction theory of polarized algebraic varieties we define two convex-geometric notions: the Q-codegree and the nef value of a rational polytope P. We define the adjoint polytope P^(s) as the set of those points in P, whose lattice distance to every facet of P is at least s. We prove a structure theorem for lattice polytopes with high Q-codegree. If P^(s) is empty for some s < 2/(dim(P)+2), then P has lattice width one. This has consequences in Ehrhart theory and on polarized toric varieties with dual defect. We remark that polyhedral adjunction theory even works in cases where the canonical divisor is not Q-Cartier. Moreover, we illustrate how classification results in adjunction theory can be translated into new classification results for lattice polytopes.

EDUCATION IN ECONOMIC THEORY  

Directory of Open Access Journals (Sweden)

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

Design Theory in Information Systems  

Directory of Open Access Journals (Sweden)

Full Text Available The aim of this paper is to explore an important category of information systems knowledge that is termed “design theory”. This knowledge is distinguished as the fifth of five types of theory: (i theory for analysing and describing, (ii theory for understanding, (iii theory for predicting, (iv theory for explaining and predicting, and (v theory for design and action. Examples of design theory in information systems are provided, with associated research methods. The limited understanding and recognition of this type of theory in information systems indicates that further debate concerning its nature and role in our discipline is needed.

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

Directory of Open Access Journals (Sweden)

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

Este autor sustenta que la teoría de la decisión puede sostenerse sobre bases causales o no causales, siendo la Teoría Causal de la Decisión un modelo necesario para el análisis de este tipo de problemas. En casos particulares como en la Paradoja de Newcomb, las teorías no causales de la decisión serían insuficientes. A continuación se presentarán brevemente las nociones básicas del análisis de decisiones, para en segundo lugar explicar en detalle algunos aspectos de la Paradoja de Newcomb. Finalmente se presentan las tesis principales de la teoría de Lewis y algunas posibles objeciones de la misma.

David Lewis’s Neglected Challenge: It’s Me or God  

Directory of Open Access Journals (Sweden)

Full Text Available I begin by sketching a dialectic typical of modern discussions of the ontological argument and explain the underlying modal principles. I will not pursue this well-worn dialectic. Instead I will explicate David Lewis’s valid reconstruction (in first order predicate logic of St Anselm’s argument in Proslogion-II. Lewis’s objections to this argument are based on his idiosyncratic views about modality. Implicitly, Lewis presents a challenge: either I am right about modality, or there is a sound version of the ontological argument. More specifically, Lewis claims there is no good reason to supposethere is anything special about the actual world. I suggest there is good reason to think that must be incorrect. Thus we are left with a formal version of the ontological argument for God’s existence that for all we have seen here looks eminently viable.

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

Directory of Open Access Journals (Sweden)

Full Text Available The American Dream is a recurrent theme in American literature. In this response, this paper is an attempt to expose the destructive effects of the dream on the human spirit. It is also shown, through the analysis of David Mamet’s glengarry Glen Ross, that despite the promise of the dream it contains many contradictions. Beneath the seeming simple surface of the play lies a deep current of meanings that reflect the calamities of modern American life, and in a broader sense, the modern world. This article indicates how capitalism inculcates ideologies in the mind of individuals in order to facilitate the exploiting process and unquestioning subordination. Ragged individualism, for instance, as  the most prominent of these ideologies, disrupts all communal bonds and even exceeds to the disintegration of friendship and family life.

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

Directory of Open Access Journals (Sweden)

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

Section 1: Monitoring the global carbon cycle: A tribute to Charles David Keeling  

Science.gov (United States)

The CO2 concentration of our atmosphere is increasing. This fact was detected by Charles David Keeling after he designed and deployed his program of CO2 measurements at Mauna Loa and Antarctica in the 1950s. These measurements continue to this day in collaboration with the National Oceanic and Atmospheric Administration. Their cumulative display—updated regularly—is often known as the Keeling Curve. More than any other scientific record, this graph has motivated the growing level of public concern that has now made carbon sequestration a commonly-known concept. Can carbon sequestration help reverse the trend shown in the Keeling Curve? The challenge of this question is the reason this book was assembled.

Set theory and physics  

Science.gov (United States)

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

Condensed Matter Field Theory  

Science.gov (United States)

Over the past few decades, in concert with ground-breaking experimental advances, condensed matter theory has drawn increasingly from the language of low-energy quantum field theory. This primer is aimed at elevating graduate students of condensed matter theory to a level where they can engage in independent research. It emphasizes the development of modern methods of classical and quantum field theory with applications oriented around condensed matter physics. Topics covered include second quantization, path and functional field integration, mean-field theory and collective phenomena, the renormalization group, and topology. Conceptual aspects and formal methodology are emphasized, but the discussion is rooted firmly in practical experimental application. As well as routine exercises, the text includes extended and challenging problems, with fully worked solutions, designed to provide a bridge between formal manipulations and research-oriented thinking. This book will complement graduate level courses on theoretical quantum condensed matter physics. Spans the field of modern condensed matter theory focusing on field theory techniques Written to facilitate learning, with numerous challenging exercises, with fully worked solutions, aimed at physicists starting graduate-level courses The theoretical methods are firmly set in concrete experimental applications

In the classical continuum limit, it reduces to a free theory, but at non-zero lattice spacing it is an interacting theory 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.

Future dynamics in theories  

Science.gov (United States)

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

Handbook of graph theory  

CERN Document Server

In the ten years since the publication of the best-selling first edition, more than 1,000 graph theory papers have been published each year. Reflecting these advances, Handbook of Graph Theory, Second Edition provides comprehensive coverage of the main topics in pure and applied graph theory. This second edition-over 400 pages longer than its predecessor-incorporates 14 new sections. Each chapter includes lists of essential definitions and facts, accompanied by examples, tables, remarks, and, in some cases, conjectures and open problems. A bibliography at the end of each chapter provides an ex

Elementary matrix theory  

CERN Document Server

The usefulness of matrix theory as a tool in disciplines ranging from quantum mechanics to psychometrics is widely recognized, and courses in matrix theory are increasingly a standard part of the undergraduate curriculum.This outstanding text offers an unusual introduction to matrix theory at the undergraduate level. Unlike most texts dealing with the topic, which tend to remain on an abstract level, Dr. Eves' book employs a concrete elementary approach, avoiding abstraction until the final chapter. This practical method renders the text especially accessible to students of physics, engineeri

Quaternionic quantum field theory  

International Nuclear Information System (INIS)

We show that a quaternionic quantum field theory can be formulated when the numbers of bosonic and fermionic degrees of freedom are equal and the fermions, as well as the bosons, obey a second order wave equation. The theory takes the form of either a functional integral with quaternion-imaginary Lagrangian, or a Schroedinger equation and transformation theory for quaternion-valued wave functions, with a quaternion-imaginary Hamiltonian. The connection between the two formulations is developed in detail, and many related issues, including the breakdown of the correspondence principle and the Hilbert space structure, are discussed.

Quantum electronics basic theory  

CERN Document Server

Quantum Electronics, Volume 1: Basic Theory is a condensed and generalized description of the many research and rapid progress done on the subject. It is translated from the Russian language. The volume describes the basic theory of quantum electronics, and shows how the concepts and equations followed in quantum electronics arise from the basic principles of theoretical physics. The book then briefly discusses the interaction of an electromagnetic field with matter. The text also covers the quantum theory of relaxation process when a quantum system approaches an equilibrium state, and explai
