  2. Piecewise linear actions and Zimmer's program

    OpenAIRE

    Ye, Shengkui

    2013-01-01

    We consider Zimmer's program of lattice actions on surfaces by PL homomorphisms. It is proved that when the surface is not the torus or Klein bottle the action of any finite-index subgroup of SL(n,Z), n>4, (more generally for any 2-big lattice), factors through a finite group action. The proof is based on an establishment of a PL version of Reeb-Thurston's stability.

  4. Simons Symposium

    CERN Document Server

    Hassett, Brendan; Tschinkel, Yuri

    2017-01-01

    Based on the Simons Symposia held in 2015, the proceedings in this volume focus on rational curves on higher-dimensional algebraic varieties and applications of the theory of curves to arithmetic problems. There has been significant progress in this field with major new results, which have given new impetus to the study of rational curves and spaces of rational curves on K3 surfaces and their higher-dimensional generalizations. One main recent insight the book covers is the idea that the geometry of rational curves is tightly coupled to properties of derived categories of sheaves on K3 surfaces. The implementation of this idea led to proofs of long-standing conjectures concerning birational properties of holomorphic symplectic varieties, which in turn should yield new theorems in arithmetic. This proceedings volume covers these new insights in detail. .

  12. Tribute to Daniel Simon

    2011-01-01

    Daniel Simon, PS Division Leader from 1994 to 1999, died on 2 June, 2011, at the age of 74, in Nancy. CERN owes him for a great number of contributions to the experimental areas around the PS and the existence of the Antiproton Decelerator (AD).   Daniel came to CERN in 1962 from the University of Nancy. He first worked in the Nuclear Physics Apparatus (NPA) Division on the electrostatic separators for the secondary beams at the PS, a subject he also chose for his thesis. Then, as a member of the PS-Division, he designed a variety of beam lines, including those providing protons and antiprotons to ICE, the decisive experiment for CERN to launch the antiproton project, based on stochastic cooling. His contributions to the initial layout and further evolution of the experimental areas of LEAR were essential for the success of the LEAR programme. He subsequently drove the decision and worked on the conversion of LEAR into LEIR for the provision of lead-ions to the LHC. He was one of the leaders of t...

    We study SU(N) Yang-Mills-Chern-Simons theory in the presence of defects that shift the Chern-Simons level from a holographic point of view by embedding the system in string theory. The model is a D3-D7 system in Type IIB string theory, whose gravity dual is given by the AdS soliton background with probe D7 branes attaching to the AdS boundary along the defects. We holographically renormalize the free energy of the defect system with sources, from which we obtain the correlation functions for certain operators naturally associated to these defects. We find interesting phase transitions when the separation of the defects as well as the temperature are varied. We also discuss some implications for the Fractional Quantum Hall Effect and for 2-dimensional QCD.

  1. Chern-Simons Modified Gravity

    2013-09-01

    This presentation will be based on my, undergraduate, thesis at Aristotle University of Thessoliniki with the same subject, supervised by Professor Demetrios Papadopoulos. I will first present the general mathematical formulation of the Chern-Simons (CS) modified gravity, which is split in a dynamical and a non-dynamical context, and the different physical theories which suggest this modification. Then proceed by examing the possibility that the CS theory shares solutions with General Relativity in both contexts. In the non-dynamical context I will present a new, undocumented solution as well as all the other possible solutions found to date. I will conclude by arguing that General Relativity and CS Theory share any solutions in the dynamical context.

  2. Canonical Chern-Simons gravity

    Science.gov (United States)

    Sarkar, Souvik; Vaz, Cenalo

    2017-07-01

    We study the canonical description of the axisymmetric vacuum in 2 +1 -dimensional gravity, treating Einstein's gravity as a Chern-Simons gauge theory on a manifold with the restriction that the dreibein is invertible. Our treatment is in the spirit of Kuchař's description of the Schwarzschild black hole in 3 +1 dimensions, where the mass and angular momentum are expressed in terms of the canonical variables and a series of canonical transformations that turn the curvature coordinates and their conjugate momenta into new canonical variables is performed. In their final form, the constraints are seen to require that the momenta conjugate to the Killing time and curvature radius vanish, and what remains is the mass, the angular momentum, and their conjugate momenta, which we derive. The Wheeler-DeWitt equation is trivial and describes time independent systems with wave functions described only by the total mass and total angular momentum.

    In this article, former US Senator Paul Simon notes that, in his lifetime, the population of the world has tripled and is expected to quadruple. Among the effects of this population growth will be a 55% increase in nitrate emissions that will feed algae and compromise fish supplies. The US was extremely short-sighted when it reduced funding for the international family planning (FP) programs that benefit all nations. False accusations that the UN Population Fund (UNFPA) operates with a "bloated bureaucracy" ignore the fact that this agency has only 166 employees. More appropriate criticism would assert that the task the UNFPA is trying to accomplish is too important and too vast for such a small staff. Without FP programs, earth would now have to support an additional 400 million people. While contraceptive use by married women in developing countries has increased from 10% in 1965 to above 50% today and life expectancy is increasing, we must recognize the fact that we are currently unable to provide most of the world's population with safe water and sanitation and that increased population size will only exacerbate this problem. Encouraging voluntary FP is humanitarian and prudent and will help protect the entire population of the world.

    Dravo Lime has for many years supplied magnesium containing lime in the ranges of 3-6% MgO. Several years ago Dravo Lime realized the potential operating savings its FGD customers could benefit from if magnesium could be recovered from FGD waste streams. As a result, several different proprietary processes have been developed for the recovery of magnesium hydroxide. These recovery processes include steps for magnesium hydroxide separation, purification, and crystal growth. The process implemented at The Cincinnati Gas Electric Company`s Wm. H. Zimmer Station was piloted by Dravo Lime Company at Allegheny Power System`s Mitchell Station near Monongahela, PA during the fourth quarter in 1989 and first quarter in 1990. This pilot work was the foundation for further development of the ThioClear process at Dravo`s pilot plant at CG&E Miami Fort Station. The ThioClear process is a closed loop version of the magnesium hydroxide recovery process with the same unit operations and products but also including an absorber tower for scrubbing flue gas. Testing at Miami Fort of the ThioClear process led to improvements in separation of magnesium hydroxide from gypsum that are part of the magnesium hydroxide recovery process installed at Zimmer Station.

    CERN Multimedia

    2011-01-01

    Simon van der Meer was a true giant of modern particle physics, though a gentle one. His contributions to accelerator science remain vital for the operation of accelerators such as the LHC today. Simon was an electrical engineer who grew up in The Hague, moving on to Delft University to study electrical engineering. After a short stint with Philips, he came to CERN in 1956, just two years after the lab opened, and remained with us until his retirement in 1990.   Simon was an incredibly inventive man. When confronted with a problem, he would sink into deep reflection, rarely emerging until he had a solution. One of us, Steve Myers, remembers him as a man who did not suffer fools gladly, and who was extremely taciturn. Simon would never use two words where one would suffice. But that one word would invariably be the right one. Simon is best known for his contribution to the SPS collider project, for which he was awarded the Nobel Prize, jointly with Carlo Rubbia, in 1984. Stochastic cooling, the in...

    Energy Technology Data Exchange (ETDEWEB)

    Lykken, J.D.

    1990-04-01

    Anyons are particles with fractional statistics. They can exist as point particles in a 2+1 dimension, or as quasiparticles in quasiplanar condensed matter systems in the real world. Anyonic particles can be modeled by ordinary bosons or fermions coupled to a statistical'' Chern-Simons abelian gauge field. For certain values of the statistics phase, a plasma of anyons in the Chern-Simons description is a superconductor. Anyonic superconductivity may represent an idealized limit of a new type of superconductor in real systems, perhaps encompassing the recently discovered high {Tc} copper oxides. 42 refs.

  11. A cognitive movement scientist's view on the link between thought and action: insights from the "Badische Zimmer" metaphor.

    Science.gov (United States)

    Hossner, Ernst-Joachim

    2009-01-01

    The problem of a bidirectional link between thought and action is approached from the perspective of cognitive movement science. The metaphor of the "Badische Zimmer" - an adaptation of Searle's Chinese room metaphor - is used to illustrate shortcomings in the classical conception of linear information processing and to introduce some features which current theories of movement control and learning should embrace. On this basis, the case is made for a return to an ideomotor view of motor control and learning based on effect prediction (E') as a function of the situational context (S') and one's own motor responses (R'). The relevance of the derived concept of sensorimotor chains linking elementary S'R'E' units in the course of motor learning is finally discussed with respect to potential implications for an integrative theory of perception, action, and decision making.

    The Simons Array is a next generation cosmic microwave background (CMB) polarization experiment whose science target is a precision measurement of the B-mode polarization pattern produced both by inflation and by gravitational lensing. As a continuation and extension of the successful POLARBEAR experimental program, the Simons Array will consist of three cryogenic receivers each featuring multichroic bolometer arrays mounted onto separate 3.5m telescopes. The first of these, also called POLARBEAR-2A, will be the first to deploy in late 2016 and has a large diameter focal plane consisting of dual-polarization dichroic pixels sensitive at 95 GHz and 150 GHz. The POLARBEAR-2A focal plane will utilize 7,588 antenna-coupled superconducting transition edge sensor (TES) bolometers read out with SQUID amplifiers using frequency domain multiplexing techniques. The next two receivers that will make up the Simons Array will be nearly identical in overall design but will feature extended frequency capability. The combination of high sensitivity, multichroic frequency coverage and large sky area available from our mid-latitude Chilean observatory will allow Simons Array to produce high quality polarization sky maps over a wide range of angular scales and to separate out the CMB B-modes from other astrophysical sources with high fidelity. After accounting for galactic foreground separation, the Simons Array will detect the primordial gravitational wave B-mode signal to r > 0.01 with a significance of > 5σ and will constrain the sum of neutrino masses to 40 meV (1σ) when cross-correlated with galaxy surveys. We present the current status of this funded experiment, its future, and discuss its projected science return.

    About 30 electric utility units with a combined total of 15,000 MW utilize magnesium enhanced lime flue gas desulfurization (FGD) systems. A disadvantage of this and other inhibited or natural oxidation wet FGD systems is the capital and operating cost associated with landfill disposal of the calcium sulfite based solids. Fixation to stabilize the solids for compaction in a landfill also consumes fly ash that otherwise may be marketable. This Executive Summary describes efforts to dewater the magnesium hydroxide and gypsum slurries and then process the solids into a more user friendly and higher value form. To eliminate the cost of solids disposal in its first generation Thiosorbic® system, the Dravo Lime Company developed the ThioClear® process that utilizes a magnesium based absorber liquor to remove S02 with minimal suspended solids. Magnesium enhanced lime is added to an oxidized bleed stream of thickener overflow (TOF) to produce magnesium hydroxide [Mg(OH)2] and gypsum (CaS04 • 2H20), as by-products. This process was demonstrated at the 3 to 5 MW closed loop FGD system pilot plant at the Miami Fort Station of Cinergy, near Cincinnati, Ohio with the help of OCDO Grant Agreement CDO/D-91-6. A similar process strictly for'recovery and reuse of Mg(OH)2 began operation at the Zimmer Station of Cinergy in late 1994 that can produce 900 pounds of Mg(OH)2 per hour and 2,600 pounds of gypsum per hour. This by-product plant, called the Zimmer Slipstream Magnesium Hydroxide Recovery Project Demonstration, was conducted with the help of OCDO Grant Agreement CDO/D-921-004. Full scale ThioClear® plants began operating in 1997 at the 130 MW Applied Energy Services plant, in Monaca, PA, and in year 2000 at the 1,330 MW Allegheny Energy Pleasants Station at St. Marys, WV.

    Junex is the leading oil and gas producer in Quebec. A review of their recent launch of the St. Simon natural gas exploration drilling project near St. Hyacinth was presented. The project involved re-entering a well hole originally drilled by Shell in 1969. Drilling began on September 8, 2005. Today's economical and technical context, combined with a new understanding of geology, has convinced the company to re-enter the well to test its commercial production capacity and to evaluate its resource potential. Junex has signed an agreement with Petrolia, in which Petrolia will receive a 10 per cent interest in the Shell St. Simon well and an option to acquire a 10 per cent interest into the production and development phase of the project in case of a gas discovery. According to internal studies, the potential extension of the trap could contain 100 Bcf of gas. Junex is also continuing its efforts to develop a natural gas underground storage facility beneath the Becancour industrial park. It was noted that with more than 4 million acres under exploration permit in Quebec, Junex's strategy to date has consisted of careful management of exploration risks. The partners in the St. Simon project are Junex, Gastem and Petrolia. It was also noted that Junex holds a 19 per cent interest in Petrolia stock. 1 fig.

  19. Self-dual Chern-Simons theories

    Dunne, Gerald

    1995-01-01

    Self-dual Chern-Simons theories form a new class of self-dual gauge theories and provide a field theoretical formulation of anyonic excitations in planar (i.e., two-space-dimensional) systems. Much of the recent attention of these theories is due to the surprising and novel ways in which they differ from the standard Maxwell, or Yang-Mills, gauge theories. These Chern-Simons theories are particular to planar systems and have therefore received added research impetus from recent experimental and theoretical breakthroughs in actual planar condensed-matter systems, such as the quantum Hall effect. This book gives a pedagogical introduction to the basic properties of the "self-dual" Chern-Simons theories, concluding with an overview of more advanced results and an extensive bibliography. Such models possess Bogomol'nyi energy bounds, topological charges, vortex solutions, and supersymmetric extensions, features which are familiar from other well-known self-dual systems such as instantons, monopoles, and vortices....

    Five-dimensional Chern-Simons theory with (anti-)de Sitter SO(1,5) or SO(2,4) gauge invariance presents an alternative to general relativity with cosmological constant. We consider the zero modes of its Kaluza-Klein compactification to four dimensions. Solutions with vanishing torsion are obtained in the cases of a spherically symmetric 3-space and of a homogeneous and isotropic 3-space, which reproduce the Schwarzshild-de Sitter and ΛCDM cosmological solutions of general relativity. We also check that vanishing torsion is a stable feature of the solutions. (orig.)

Since guilt seems to be a very important topic in the Austrian literary tradition, this article also tries to establish whether and how Hotschnig takes up this grand Austrian tradition of writing about guilt.

  7. Chern-Simons (super)gravity

    CERN Document Server

    2016-01-01

    This book grew out of a set of lecture notes on gravitational Chern–Simons (CS) theories developed over the past decade for several schools and different audiences including graduate students and researchers.CS theories are gauge-invariant theories that can include gravity consistently. They are only defined in odd dimensions and represent a very special class of theories in the Lovelock family. Lovelock gravitation theories are the natural extensions of General Relativity for dimensions greater than four that yield second-order field equations for the metric. These theories also admit local supersymmetric extensions where supersymmetry is an off-shell symmetry of the action, as in a standard gauge theory.Apart from the arguments of mathematical elegance and beauty, the gravitational CS actions are exceptionally endowed with physical attributes that suggest the viability of a quantum interpretation. CS theories are gauge-invariant, scale-invariant and background independent; they have no dimensional couplin...

  8. How ‘social’ is the social Simon effect?

    Directory of Open Access Journals (Sweden)

    Thomas eDolk

    2011-05-01

    Full Text Available In the standard Simon task, participants carry out spatially defined responses to non-spatial stimulus attributes. Responses are typically faster when stimulus location and response location correspond. This effect disappears when a participant responds to only one of the two stimuli and reappears when another person carries out the other response. This social Simon effect has been considered as providing an index for action co-representation. Here, we investigated whether joint-action effects in a social Simon task involve mechanisms of action co-representation, as measured by the amount of incorporation of another person’s action. We combined an auditory social Simon task with a manipulation of the sense of ownership of another person’s hand (Rubber Hand Illusion. If the social Simon effect is established by action co-representation, then the incorporation of the other person’s hand into one’s own body representation should increase the social Simon effect (synchronous > asynchronous stroking. However, we found the social Simon effect to be smaller in the synchronous as compared to the asynchronous stroking condition (Experiment 1, suggesting that the social Simon effect reflects the separation of spatial action events rather than the integration of the other person’s action. This effect is independent of the active involvement (Experiment 2 and the presence of another person (Experiment 3. These findings suggest that the ‘social’ Simon effect is not really social in nature but is established when an interaction partner produces events that serve as a spatial reference for one’s own actions.

    We investigated the appearance of Chern-Simons terms in electrodynamics at the surface or interface of materials. The requirement of locality, gauge invariance, and renormalizability in this model is imposed. Scattering and reflection of electromagnetic waves in three different homogeneous layers of media is determined. Snell's law is preserved. However, the transmission and reflection coefficient depend on the strength of the Chern-Simons interaction (connected with Hall conductance), and parallel and perpendicular components are mixed.

    We construct a manifestly covariant differential Noether charge for theories with Chern-Simons terms in higher dimensional spacetimes. This is in contrast to Tachikawa’s extension of the standard Lee-Iyer-Wald formalism which results in a non-covariant differential Noether charge for Chern-Simons terms. On a bifurcation surface, our differential Noether charge integrates to the Wald-like entropy formula proposed by Tachikawa in (arXiv:hep-th/0611141v2).

    2017-02-01

    Given a set of differential forms on an odd-dimensional noncommutative manifold valued in an internal associative algebra H , we show that the most general cubic covariant Hamiltonian action, without mass terms, is controlled by an {{{Z}}2} -graded associative algebra F with a graded symmetric nondegenerate bilinear form. The resulting class of models provide a natural generalization of the Frobenius-Chern-Simons model (FCS) that was proposed in (arXiv:1505.04957) as an off-shell formulation of the minimal bosonic four-dimensional higher spin gravity theory. If F is unital and the {{{Z}}2} -grading is induced from a Klein operator that is outer to a proper Frobenius subalgebra, then the action can be written on a form akin to topological open string field theory in terms of a superconnection valued in H\\otimes F . We give a new model of this type based on a twisting of {C}≤ft[{{{Z}}2}× {{{Z}}4}\\right] , which leads to self-dual complexified gauge fields on AdS 4. If F is 3-graded, the FCS model can be truncated consistently as to contain no zero-form constraints on-shell. Two examples thereof are a twisting of {C}[{{({{{Z}}2})}3}] that yields the original model, and the Clifford algebra C{{\\ell}2n} which provides an FCS formulation of the bosonic Konstein-Vasiliev model with gauge algebra hu≤ft({{4}n-1},0\\right) .

  16. Anomalies and Holomorphy in Super-Chern-Simons Matter Theories

    Science.gov (United States)

    Bade, Nathaniel

    Using techniques from complex analysis and q-hypergeometric function theory, we explore a generalization of the Witten-Reshetikhin-Turaev invariant of the three sphere. Specifically, we study the partition function of N = 2 Super-Chern-Simons matter theories on an ellipsoidal three sphere. To properly quantize Chern-Simons Matter theories, a sensitive cancellation of anomalies requires the half integrality of the Chern-Simons level k to match the parity mod 2 of the quadratic Casimir of the fermion representation. For abelian N=2 theories, Pasquetti observed that the Coulomb branch partition function of a family of ellipsoidal three-spheres admits a factorization precisely when k is properly quantized. In this thesis we use known formulas for the Coulomb branch partition function to prove Pasquetti's conjecture for all simple Lie groups, with matter in a direct sum of multiplicity free representations. Along the way, we recover a known relationship between the Chern-Simons level and the eigenvalues of the Dirac operator in terms of the asymptotic behavior of the double sine function. Finally, we compute the analytic continuation of torus knot observables in SU(2) Chern-Simons theory in the presence of matter.

    We explore Chern-Simons theories coupled to fundamental ghost-like matter in the large N limit at ’t Hooft coupling λ. These theories have been conjectured to be holographically dual to parity-violating, asymptotically dS{sub 4} universes with a tower of light higher-spin fields. On ℝ{sup 3}, to all orders in large-N perturbation theory, we show that Chern-Simons-ghost theories are related to ordinary Chern-Simons-matter theories by mapping N→−N and keeping λ fixed. Consequently, the bosonization duality of ordinary Chern-Simons-matter theories extends to a bosonization duality of Chern-Simons-ghost theories on ℝ{sup 3}. On S{sup 1}×S{sup 2}, in the small-S{sup 1} limit, neither N→−N nor bosonization hold, as we show by extensively studying large-N saddles of the theories with both ghost and ordinary matter. The partition functions we compute along the way can be viewed as pieces of the late-time Hartle-Hawking wavefunction for the bulk dS{sub 4} gravity theories.

    We study the phenomenological credibility of a vectorial dark matter, coupled to a Z' portal through Chern-Simons interaction. We scrutinize two possibilities of connecting a Z' with the Standard Model: (1) through kinetic mixing and (2) from a second Chern-Simons interaction. Both scenarios are characterized by suppressed nuclear recoil scatterings, rendering direct detection searches not promising. Indirect detection experiments, on the other hand, furnish complementary limits for TeV scale masses, specially with the CTA. Searches for mono-jet and dileptons signals at the LHC are important to partially probe the kinetic mixing setup. Finally we propose an UV completion of the Chern-Simons Dark Matter framework.

    Recent derivations of Cardy-like formulae in higher dimensional field theories have opened up a way of computing, via AdS/CFT, universal contributions to black hole entropy from gravitational Chern-Simons terms. Based on the manifestly covariant formulation of the differential Noether charge for Chern-Simons terms proposed in http://dx.doi.org/10.1007/JHEP05(2015)041, we compute the entropy and asymptotic charges for the rotating charged AdS black holes in higher dimensions at leading order of the fluid/gravity derivative expansion in the Einstein-Maxwell-Chern-Simons system. This gives a result that exactly matches the field theory predictions from Cardy-like formulae.

    We present an explicit expression for the grand potential of the U( N )3 superconformal Chern-Simons theory with the Chern-Simons levels being ( k, 0, - k). From the viewpoint of the Newton polygon, it is expected that the grand potential is given by the free energy of the topological string theory on the local D 5 del Pezzo geometry, though the explicit identification was a puzzle for years. We show how the expectation is realized explicitly. As a bonus, we can also study the Z_2 orbifold of this theory and find the grand potential is now given in terms of the local E 7 del Pezzo geometry.

    We present an overview of the design and status of the Polarbear-2 and the Simons Array experiments. Polarbear-2 is a cosmic microwave background polarimetry experiment which aims to characterize the arc-minute angular scale B-mode signal from weak gravitational lensing and search for the degree angular scale B-mode signal from inflationary gravitational waves. The receiver has a 365 mm diameter focal plane cooled to 270 mK. The focal plane is filled with 7588 dichroic lenslet-antenna-coupled polarization sensitive transition edge sensor (TES) bolometric pixels that are sensitive to 95 and 150 GHz bands simultaneously. The TES bolometers are read-out by SQUIDs with 40 channel frequency domain multiplexing. Refractive optical elements are made with high-purity alumina to achieve high optical throughput. The receiver is designed to achieve noise equivalent temperature of 5.8 \\upmu K_CMB√{s} in each frequency band. Polarbear-2 will deploy in 2016 in the Atacama desert in Chile. The Simons Array is a project to further increase sensitivity by deploying three Polarbear-2 type receivers. The Simons Array will cover 95, 150, and 220 GHz frequency bands for foreground control. The Simons Array will be able to constrain tensor-to-scalar ratio and sum of neutrino masses to σ (r) = 6× 10^{-3} at r = 0.1 and sum m_{\\upnu } (σ =1) to 40 meV.

    2017-11-01

    We present an elementary review of some aspects of Chern-Simons theory with complex gauge group SL(N, { C}) . We discuss some of the challenges in defining the theory as a full-fledged TQFT, as well as some successes inspired by the 3d-3d correspondence. The 3d-3d correspondence relates partition functions (and other aspects) of complex Chern-Simons theory on a 3-manifold M to supersymmetric partition functions (and other observables) in an associated 3d theory T[M] . Many of these observables may be computed by supersymmetric localization. We present several prominent applications to 3-manifold topology and number theory in light of the 3d-3d correspondence. This is a contribution to the review issue ‘Localization techniques in quantum field theories’ (ed Pestun and Zabzine) which contains 17 chapters available at [1].

    We study the topological entanglement negativity between two spatial regions in (2+1)-dimensional Chern-Simons gauge theories by using the replica trick and the surgery method. For a bipartitioned or tripartitioned spatial manifold, we show how the topological entanglement negativity depends on the presence of quasiparticles and the choice of ground states. In particular, for two adjacent non-contractible regions on a tripartitioned torus, the entanglement negativity provides a simple way to distinguish Abelian and non-Abelian theories. Our method applies to a Chern-Simons gauge theory defined on an arbitrary oriented (2+1)-dimensional spacetime manifold. Our results agree with the edge theory approach in a recent work (X. Wen, S. Matsuura and S. Ryu, arXiv:1603.08534).

    Higher dimensional Chern-Simons theories, even though constructed along the same topological pattern as in 2+1 dimensions, have been shown recently to have generically a non-vanishing number of degrees of freedom. In this paper, we carry out the complete Dirac Hamiltonian analysis (separation of first and second class constraints and calculation of the Dirac bracket) for a group G x U(1). We also study the algebra of surface charges that arise in the presence of boundaries and show that it is isomorphic to the WZW{sub 4} discussed in the literature. Some applications are then considered. It is shown, in particular, that Chern-Simons gravity in dimensions greater than or equal to five has a propagating torsion. (orig.).

    The operator formalism for Chern-Simons gauge theory with gauge group SU(N) is presented. The connection with rational conformal field theory is shown explicitly by identifying a basis for the Hilbert space of the theory with the set of characters corresponding to a Wess-Zumino-Witten model for SU(N). Knot operators are constructed performing the calculation of matrix elements of Wilson line operators on this Hilbert space. Using these operators a representation of the Verlinde operators in the context of Chern-Simons gauge theory is obtained. As an application of the use of these operators to knot theory, the Jones polynomial for toral knots is explicitly computed. (orig.).

  11. Gauged baby Skyrme model with a Chern-Simons term

    2017-02-01

    The properties of the multisoliton solutions of the (2 +1 )-dimensional Maxwell-Chern-Simons-Skyrme model are investigated numerically. Coupling to the Chern-Simons term allows for existence of the electrically charge solitons which may also carry magnetic fluxes. Two particular choices of the potential term is considered: (i) the weakly bounded potential and (ii) the double vacuum potential. In the absence of gauge interaction in the former case the individual constituents of the multisoliton configuration are well separated, while in the latter case the rotational invariance of the configuration remains unbroken. It is shown that coupling of the planar multi-Skyrmions to the electric and magnetic field strongly affects the pattern of interaction between the constituents. We analyze the dependency of the structure of the solutions, the energies, angular momenta, electric and magnetic fields of the configurations on the gauge coupling constant g , and the electric potential. It is found that, generically, the coupling to the Chern-Simons term strongly affects the usual pattern of interaction between the skyrmions, in particular the electric repulsion between the solitons may break the multisoliton configuration into partons. We show that as the gauge coupling becomes strong, both the magnetic flux and the electric charge of the solutions become quantized although they are not topological numbers.

    Chern-Simons models for gravity are interesting because they provide a truly gauge-invariant action principle in the fiber-bundle sense. So far, their main drawback has largely been its perceived remoteness from standard General Relativity, based on the presence of higher powers of the curvature in the Lagrangian (except, remarkably, for three-dimensional spacetime). Here we report on a simple model that suggests a mechanism by which standard General Relativity in five-dimensional spacetime may indeed emerge at a special critical point in the space of couplings, where additional degrees of freedom and corresponding 'anomalous' Gauss-Bonnet constraints drop out from the Chern-Simons action. To achieve this goal, both the Lie algebra g and the symmetric g-invariant tensor that define the Chern-Simons Lagrangian are constructed by means of the Lie algebra S-expansion method with a suitable finite Abelian semigroup S. The results are generalized to arbitrary odd dimensions, and the possible extension to the case of eleven-dimensional supergravity is briefly discussed.

    POLARBEAR is a cosmic microwave background (CMB) polarization experiment located in the Atacama desert in Chile. The science goals of the POLARBEAR project are to do a deep search for CMB B-mode polarization created by inflationary gravitational waves, as well as characterize the CMB B-mode signal from gravitational lensing. POLARBEAR-1 started observations in 2012, and the POLARBEAR team has published a series of results from its first season of observations, including the first measurement of a non-zero B-mode polarization angular power spectrum, measured at sub-degree scales where the dominant signal is gravitational lensing of the CMB. Recently, we released an improved measurement of the B-mode polarization power spectrum, improving our band-power uncertainties by a factor of two, by adding new data from our second observing season and re-analyzing the combined data set.To further improve on these measurements, POLARBEAR is expanding to include an additional two telescopes with multi-chroic receivers observing at 95, 150, 220, and 270 GHz, known as the Simons Array. With high sensitivity and large sky coverage, the Simons Array will create a detailed survey of B-mode polarization, and its spectral information will be used to extract the CMB signal from astrophysical foregrounds. We will present the latest POLARBEAR results, as well as the status of development of the Simons Array and its expected capabilities.

    We analyze holographic field theory dual to Lovelock Chern-Simons anti-de Sitter (AdS) gravity in higher dimensions using first order formalism. We first find asymptotic symmetries in the AdS sector showing that they consist of local translations, local Lorentz rotations, dilatations and non-Abelian gauge transformations. Then, we compute 1-point functions of energy-momentum and spin currents in a dual conformal field theory and write Ward identities. We find that the holographic theory possesses Weyl anomaly and also breaks non-Abelian gauge symmetry at the quantum level.

    The Maxwell-Chern-Simons (MCS) theory with a planar boundary is considered. The boundary is introduced according to Symanzik's basic principles of locality and separability. A method of investigation is proposed, which, avoiding the straight computation of correlators, is appealing for situations where the computation of propagators, modified by the boundary, becomes quite complex. For the MCS theory, the outcome is that a unique solution exists, in the form of chiral conserved currents, satisfying a Kac-Moody algebra, whose central charge does not depend on the Maxwell term.

    2017-09-01

    Scientific discovery via numerical simulations is important in modern astrophysics. This relatively new branch of astrophysics has become possible due to the development of reliable numerical algorithms and the high performance of modern computing technologies. These enable the analysis of large collections of observational data and the acquisition of new data via simulations at unprecedented accuracy and resolution. Ideally, simulations run until they reach some pre-determined termination condition, but often other factors cause extensive numerical approaches to break down at an earlier stage. In those cases, processes tend to be interrupted due to unexpected events in the software or the hardware. In those cases, the scientist handles the interrupt manually, which is time-consuming and prone to errors. We present the Simulation Monitor (SiMon) to automatize the farming of large and extensive simulation processes. Our method is light-weight, it fully automates the entire workflow management, operates concurrently across multiple platforms and can be installed in user space. Inspired by the process of crop farming, we perceive each simulation as a crop in the field and running simulation becomes analogous to growing crops. With the development of SiMon we relax the technical aspects of simulation management. The initial package was developed for extensive parameter searchers in numerical simulations, but it turns out to work equally well for automating the computational processing and reduction of observational data reduction.

    Human lipodystrophies are uncommon disorders, with important clinical consequences, which are often undiagnosed. The Barraquer-Simons syndrome is a form of partial symmetric lipodystrophy of unknown etiology, characterized by the loss of subcutaneous adipose tissue, limited to upper part of the body. Insulin resistance and metabolic complications are less common than with other lipodystrophy subtypes. Patients usually have decreased serum complement-component 3 levels, associated with complement activation by the alternative pathway, which may indicate the presence of renal involvement. The authors report a case of a 31-year-old woman with progressive loss of subcutaneous fat, limited to the face, neck and thorax. She presented no severe metabolic complications, neither signs of insulin resistance. Laboratory tests revealed mild dyslipidemia, and low serum levels of complement-component 3. Clinical and biochemical characteristics were consistent with the diagnosis of Barraquer-Simons syndrome. The present case illustrates the importance of recognizing the clinical features of this lipodystrophic syndrome, which may present potentially severe consequences and psychological distress. A brief overview is made, addressing the clinical signs of the disease, its course, and how to manage it.

    A number of studies have shown that training on action video games improves various aspects of visual cognition including selective attention and inhibitory control. Here, we demonstrate that action video game play can also reduce the Simon Effect, and, hence, may have the potential to improve response selection during the planning and execution of goal-directed action. Non-game-players were randomly assigned to one of four groups; two trained on a first-person-shooter game (Call of Duty) on either Microsoft Xbox or Nintendo DS, one trained on a visual training game for Nintendo DS, and a control group who received no training. Response times were used to contrast performance before and after training on a behavioral assay designed to manipulate stimulus-response compatibility (the Simon Task). The results revealed significantly faster response times and a reduced cost of stimulus-response incompatibility in the groups trained on the first-person-shooter game. No benefit of training was observed in the control group or the group trained on the visual training game. These findings are consistent with previous evidence that action game play elicits plastic changes in the neural circuits that serve attentional control, and suggest training may facilitate goal-directed action by improving players' ability to resolve conflict during response selection and execution.

  4. Chern-Simons-Rozansky-Witten topological field theory

    Kapustin, Anton; Saulina, Natalia

    2009-12-01

    We construct and study a new topological field theory in three dimensions. It is a hybrid between Chern-Simons and Rozansky-Witten theory and can be regarded as a topologically-twisted version of the N=4d=3 supersymmetric gauge theory recently discovered by Gaiotto and Witten. The model depends on a gauge group G and a hyper-Kähler manifold X with a tri-holomorphic action of G. In the case when X is an affine space, we show that the model is equivalent to Chern-Simons theory whose gauge group is a supergroup. This explains the role of Lie superalgebras in the construction of Gaiotto and Witten. For general X, our model appears to be new. We describe some of its properties, focusing on the case when G is simple and X is the cotangent bundle of the flag variety of G. In particular, we show that Wilson loops are labeled by objects of a certain category which is a quantum deformation of the equivariant derived category of coherent sheaves on X.

  9. The relationship between language proficiency and attentional control in Cantonese-English bilingual children: Evidence from Simon, Simon switching, and working memory tasks

    Full Text Available By administering Simon, Simon switching, and operation-span working memory tasks to Cantonese-English bilingual children who varied in their first-language (L1, Cantonese and second-language (L2, English proficiencies, as quantified by standardized vocabulary test performance, the current study examined the effects of L1 and L2 proficiency on attentional control performance. Apart from mean performance, we conducted ex-Gaussian analyses to capture the modal and positive-tail components of participants’ reaction time distributions in the Simon task. Bilinguals’ L2 proficiency was associated with higher scores in the operation span task, and a shift of reaction time distributions in incongruent trials, relative to congruent trials (Simon effect in µ, and the tail size of reaction time distributions (τ regardless of trial types. Bilinguals’ L1 proficiency, which was strongly associated with participants’ age, showed similar results, except that it was not associated with the Simon effect in µ. In contrast, neither bilinguals’ L1 nor L2 proficiency modulated the global switch cost or local switch cost in the Simon switching task. After taking into account potential cognitive maturation by partialling out the participants’ age, only (a scores in the working memory task and (b RT in incongruent trials and (c Simon effect in µ in the Simon task could still be predicted by bilinguals’ L2 proficiency. Overall, the current findings suggest that bilingual children’s L2 proficiency was associated with their conflict resolution and working memory capacity, but not goal maintenance or task-set switching, when they performed the cognitive tasks that demanded attentional control. This was not entirely consistent with the findings of college-age bilinguals reported in previous studies.

    Payne, Sam

    2016-01-01

    This volume grew out of two Simons Symposia on "Nonarchimedean and tropical geometry" which took place on the island of St. John in April 2013 and in Puerto Rico in February 2015. Each meeting gathered a small group of experts working near the interface between tropical geometry and nonarchimedean analytic spaces for a series of inspiring and provocative lectures on cutting edge research, interspersed with lively discussions and collaborative work in small groups. The articles collected here, which include high-level surveys as well as original research, mirror the main themes of the two Symposia. Topics covered in this volume include: Differential forms and currents, and solutions of Monge–Ampère type differential equations on Berkovich spaces and their skeletons; The homotopy types of nonarchimedean analytifications; The existence of "faithful tropicalizations" which encode the topology and geometry of analytifications; Relations between nonarchimedean analytic spaces and algebraic geometry, including lo...

  12. Non-toric cones and Chern-Simons quivers

    Science.gov (United States)

    Crichigno, P. Marcos; Jain, Dharmesh

    2017-05-01

    We obtain an integral formula for the volume of non-toric tri-Sasaki Einstein manifolds arising from nonabelian hyperkähler quotients. The derivation is based on equivariant localization and generalizes existing formulas for Abelian quotients, which lead to toric manifolds. The formula is particularly valuable in the context of AdS4 × Y 7 vacua of M-theory and their field theory duals. As an application, we consider 3d N=3 Chern-Simons theories with affine ADE quivers. While the  series corresponds to toric Y 7, the \\widehat{D} and Ê series are non-toric. We compute the volumes of the corresponding seven-manifolds and compare to the prediction from supersymmetric localization in field theory, finding perfect agreement. This is the first test of an infinite number of non-toric AdS4/CFT3 dualities.

    Supersymmetric localization provides exact results that should match QFT computations in some regularization scheme. The agreement is particularly subtle in three dimensions where complex answers from localization procedure sometimes arise. We investigate this problem by studying the expectation value of the 1/6 BPS Wilson loop in planar ABJ(M) theory at three loops in perturbation theory. We reproduce the corresponding term in the localization result and argue that it originates entirely from a non-trivial framing of the circular contour. Contrary to pure Chern-Simons theory, we point out that for ABJ(M) the framing phase is a non-trivial function of the couplings and that it potentially receives contributions from vertex-like diagrams. Finally, we briefly discuss the intimate link between the exact framing factor and the Bremsstrahlung function of the 1/2-BPS cusp.

    We probe in some depth into the structure of eleven-dimensional, osp(32|1)-based Chern-Simons supergravity, as put forward by Troncoso and Zanelli (TZ) in 1997. We find that the TZ Lagrangian may be cast as a polynomial in 1/l, where l is a length, and compute explicitly the first three dominant terms. The term proportional to 1/l{sup 9} turns out to be essentially the Lagrangian of the standard 1978 supergravity theory of Cremmer, Julia and Scherk, thus establishing a previously unknown relation between the two theories. The computation is nontrivial because, when written in a sufficiently explicit way, the TZ Lagrangian has roughly one thousand non-explicitly Lorentz-covariant terms. Specially designed algebraic techniques are used to accomplish the results.

  17. Ricci dark energy in Chern-Simons modified gravity

    Full text: Currently the accelerated expansion of the universe has been strongly confirmed by some independent experiments such as the Cosmic Microwave Background Radiation (CMBR) and Sloan Digital Sky Survey (SDSS). In an attempt to explain this phenomenon there are two possible paths; first option - propose corrections to general relativity, second option - assuming that there is a dominant component of the universe, a kind of antigravity called dark energy. Any way that we intend to follow, there are numerous models that attempt to explain this effect. One of the models of modified gravity that has stood out in recent years is the Chern-Simons modified gravity. This modification consists in the addition of the Pontryagin density, which displays violation of parity symmetry in Einstein-Hilbert action. From among the various models proposed for dark energy there are some that are based on the holographic principle, known as holographic dark energy. Such models are based on the idea that the energy density of a given system is proportional to the inverse square of some characteristic length of the system. From these studies, here we consider the model proposed by Gao et. al., a model of dark energy where the characteristic length is given by the average radius of the Ricci scalar. Thus, the dark energy density is proportional to the Ricci scalar, i.e., ρ{sub x} ∝ R. It is a phenomenologically viable model and displays results similar to that presented by the cosmological model ACDM. In this work, we have considered the Ricci dark energy model in the dynamic Chern-Simons modified gravity. We show that in this context the evolution of the scale factor is similar to that displayed by the modified Chaplygin gas. (author)

    Full Text Available The non-mimetic Afrotropical spider genus Cambalida Simon, 1909, placed within a subfamily of predominantly ant-mimicking spiders (Araneae: Corinnidae: Castianeirinae, is revised. Three species are transferred from Castianeira Keyserling, 1879 to Cambalida: C. deminuta (Simon, 1909, comb. n., C. fulvipes (Simon, 1896, comb. n. and C. loricifera (Simon, 1885, comb. n.. A fourth species, C. fagei (Caporiacco, 1939, comb. n., is transferred from Brachyphaea Simon, 1895 to Cambalida. Two species, Castianeira depygata Strand, 1916, syn. n. and C. mestrali Lessert, 1921, syn. n., are considered junior synonyms of C. fulvipes. The males of C. deminuta and C. loricifera are redescribed and their unknown females are described for the first time. The female and male of C. fulvipes and C. coriacea Simon, 1909 are also redescribed. The type material of the type species of the genus, C. insulana Simon, 1909 from Pagalu (Annobon Island, is lost, and only immature specimens have been subsequently collected from a nearby island. The species is regarded as a nomen dubium until fresh adult material can be collected. A replacement name, Cambalida simoni nom. n. is proposed for Cambalida fulvipes Simon, 1909, the latter being a secondary junior homonym of Cambalida fulvipes (Simon, 1896. The type material of this species is also lost and it is too considered nomen dubium. The following new species are described: C. compressa sp. n. from West Africa, C. dippenaarae sp. n. from southern Africa, C. griswoldi sp. n. and C. lineata sp. n. from Madagascar, and C. unica sp. n. from Cameroon. Notes are provided on the biology of each species and the distribution of the genus in the Afrotropical Region.

  19. Unification of gauge and gravity Chern-Simons theories in 3-D space-time

    Saghir, Chireen A.; Shamseddine, Laurence W.

    2017-11-01

    Chamseddine and Mukhanov showed that gravity and gauge theories could be unified in one geometric construction provided that a metricity condition is imposed on the vielbein. In this paper we are going to show that by enlarging the gauge group we are able to unify Chern-Simons gauge theory and Chern-Simons gravity in 3-D space-time. Such a unification leads to the quantization of the coefficients for both Chern-Simons terms for compact groups but not for non-compact groups. Moreover, it leads to a topological invariant quantity of the 3-dimensional space-time manifold on which they are defined.

    Mobility and parking in urban areas are often difficult for people with disabilities. Obstacles include lack of accessible information on routes, transport alternatives and parking availability, as well as fraud in the use of the specific services intended for these citizens. The SIMON project aims to improve this situation through the integration of different ICT solutions. SIMON is enhancing the European Parking Card for disable people with contactless technologies and integrates mobile solutions to support user unique identification in existing parking areas whilst preserving privacy. SIMON will also promote better mobility solutions for mobility including information, navigation and access to restricted areas.

    A variety of flue gas desulfurization (FGD) technologies have been developed to meet environmental restrictions imposed by the federal Clean Air Act and its amendments. These technologies include wet scrubber systems that dramatically reduce sulfur dioxide (SO2) emissions. Although such systems are effective, they also produce large volumes of sludge that must be dewatered, stabilized, and disposed of in landfills. Disposal is an expensive and environmentally questionable process for which suitable alternatives are needed. Wet scrubbing of flue gases with magnesium (Mg)-enhanced lime has the potential to become a leading FGD technology. When combined with aforced oxidation system, the wet sludges resulting from this process can be modified and refined to produce gypsum (CaS04∙2H2O) and magnesium hydroxide [Mg(OH)2] of sufficient purity for beneficial re-use in the construction (wallboard) and pharmaceutical industries. The pilot plant at the CINERGY Zimmer Station near Cincinnati can also produce gypsum by-products formulated to contain varying amounts of Mg(OH)2- Such materials may have value to the agriculture, forestry, and lawn-care industries as soil "conditioners", liming agents, and nutritional supplements capable of supplying calcium (Ca), Mg, and sulfur (S) for plant growth. This report describes three field studies designed to evaluate by-product gypsum and Mg-gypsum from the Zimmer Station power plant as amendments for improving the quality of mine spoils and agricultural soils that were unproductive because of phytotoxic levels of dissolved aluminum (Al) and low pH. The technical literature suggests that gypsum may be more effective than agricultural limestone for ameliorating Al toxicity below the immediate zone of application. Such considerations are important for deep-rooted plant species that attempt to utilize water and nutrients occurring at depth in the spoil/soil.

    2016-01-01

    Full Text Available In this paper, we will calculate the effective potential for a theory of multiple M2-branes. As the theory of multiple M2-branes can be described by a Chern–Simons-matter theory, this will be done by calculating the Kählerian effective potential for a Chern–Simons-matter theory. This calculation will be performed in N=1 superspace formalism. We will initially study an Abelian Chern–Simons-matter theory, and then generalize those results to the full non-Abelian Chern–Simons-matter theory. We will obtain explicit expressions for the superpropagators for this theory. These superpropagators will be used to calculate the one-loop effective potential.

    Sepehri, Alireza; Ghaffary, Tooraj; Naimi, Yaghoob; Ghaforyan, Hossein; Ebrahimzadeh, Majid

    In this paper, the formation of cylindrical wormhole during evolution of manifolds is studied. It is shown that this type of wormholes may be produced at two stages and then disappeared very fast at the third stage. First, one N-dimensional is formed by joining point-like manifolds. Then, this manifold is torn and two child manifolds plus one Chern-Simons manifold appeared. Our universe is born on one of the child manifolds and connected to the other one by Chern-Simons manifold. At the third stage, this Chern-Simons manifold-which plays the role of cylindrical wormhole, dissolves into universes and gives its energy to them and causes inflation. Thus, the Chern-Simons cylindrical wormhole is unstable and dissolves in our four-dimensional universes and another universe very fast.

    We initiate the study of a Chern-Simons action associated to the semi-direct sum of the Virasoro algebra with its coadjoint representation. This model extends the standard Chern-Simons formulation of three dimensional flat gravity and is similar to the higher-spin extension of three dimensional anti-de Sitter or flat gravity. The extension can also be constructed for the exotic but not for the cosmological constant deformation of flat gravity.

    This proceeding is based on hep-th/0605225 and it shows that the most general anomaly related effective action contains Stueckelberg, axionic and Chern-Simons-like couplings. Such couplings are generically non-trivial in orientifold string vacua. A similar analysis in quantum field theories provides similar couplings. These Chern-Simons couplings generate new signals which might be visible at LHC. (Abstract Copyright [2007], Wiley Periodicals, Inc.)

    Full Text Available Este artículo examina la relación entre la lectura crítica y el objeto crítico en laobra de la poeta y ensayista canadiense Anne Carson, principalmente los textosque surgen de su largo acercamiento a los escritos de la filósofa y mística cristiana Simone Weil. Mi lectura de Carson se centra en los deseos conflictuales de la relación crítica que se encuentran confesados y no confesados en su obra, y en las formas de intimidad que sus respuestas logran con la obra de Weil. Agudizadas por su encuentro con el pensamiento y la fe de Weil, las preguntasde Carson para la crítica ―sobre sus propios objetos y la resistencia de ellos ala interpretación, sobre la distinción entre crítica y literatura, y sobre la vanidadde la estética de la crítica misma― encuentran su articulación en varios génerosde la escritura: estudiando la complicidad de cada uno de estos con Weil, yla capacidad de cada uno a radicalizar sus cuestiones, llego a unas conclusionspropias para la crítica literaria.

  1. The Maxwell-Chern-Simons gravity, and its cosmological implications

    We consider the cosmological implications of a gravitational theory containing two vector fields coupled via a generalized Chern-Simons term. One of the vector fields is the usual Maxwell field, while the other is a constrained vector field with constant norm included in the action via a Lagrange multiplier. The theory admits a de Sitter type solution, with healthy cosmological perturbations. We also show that there are seven degrees of freedom that propagate on top of de Sitter space-time, consisting of two tensor polarizations, four degrees of freedom related to the two vector fields, and a scalar degree of freedom that makes one of the vector fields massive. We investigate the cosmological evolution of Bianchi type I space-time, by assuming that the matter content of the Universe can be described by the stiff and dust. The cosmological evolution of the Bianchi type I Universe strongly depends on the initial conditions of the physical quantities, as well as on the model parameters. The mean anisotropy parameter, and the deceleration parameter, are also studied, and we show that independently of the matter equation of state the cosmological evolution of the Bianchi type I Universe always ends in an isotropic de Sitter type phase.

  3. Asymmetrical hemispheric EEG activation evoked by stimulus position during the Simon task.

    2006-05-22

    The Simon effect has been previously shown to be asymmetric at both the behavioral and electrophysiological levels. The present investigation was aimed to clarify whether, during a Simon task, hemispheric asymmetry is also observed in the early phases of stimulus processing. In a group of healthy subjects performing the Simon task, we analyzed scalp potentials evoked by the first lateralized cue (left or right), instead of the classical readiness potential preceding the motor response. ERP results showed a significant left cortical activation to stimuli presented in the right visual field at the 140-160 ms time window. Instead, left stimuli elicited a significant activation of the right versus left hemisphere starting at the next 160-180 ms time interval. We linked this asymmetry to that observed in behavioral data: the Simon effect recorded with left stimuli is smaller than the Simon effect recorded with right stimuli. Results confirm the hypothesis that in right handed subjects, left hemisphere is specialized for motor response selection and is able to process right stimuli faster than the right hemisphere does for left stimuli.

    Herbert Simon's classic rich-get-richer model is one of the simplest empirically supported mechanisms capable of generating heavy-tail size distributions for complex systems. Simon argued analytically that a population of flavored elements growing by either adding a novel element or randomly replicating an existing one would afford a distribution of group sizes with a power-law tail. Here, we show that, in fact, Simon's model does not produce a simple power-law size distribution as the initial element has a dominant first-mover advantage, and will be overrepresented by a factor proportional to the inverse of the innovation probability. The first group's size discrepancy cannot be explained away as a transient of the model, and may therefore be many orders of magnitude greater than expected. We demonstrate how Simon's analysis was correct but incomplete, and expand our alternate analysis to quantify the variability of long term rankings for all groups. We find that the expected time for a first replication is infinite, and show how an incipient group must break the mechanism to improve their odds of success. We present an example of citation counts for a specific field that demonstrates a first-mover advantage consistent with our revised view of the rich-get-richer mechanism. Our findings call for a reexamination of preceding work invoking Simon's model and provide an expanded understanding going forward.

  5. The Influence of Negative Emotion on the Simon Effect as Reflected by P300

    2013-01-01

    Full Text Available The Simon effect refers to the phenomenon that reaction time (RT is faster when stimulus and response location are congruent than when they are not. This study used the priming-target paradigm to explore the influence of induced negative emotion on the Simon effect with event-related potential techniques (ERPs. The priming stimuli were composed of two kinds of pictures, the negative and neutral pictures, selected from the International Affective Picture System (IAPS. The target stimuli included chessboards of two color types. One was red and black the other one was green and black. Each chessboard was presented on the left or the right of the screen. The participants were asked to press the response keys according to the colors of the chessboards. It was called the congruent condition if the chessboard and the response key were on the same side, otherwise incongruent condition. In this study, the emotion-priming Simon effect was found in terms of RT and P300. Negative emotion compared with neutral emotion significantly enhanced the Simon effect in the cognitive process, reflected by a larger difference of P300 latency between the incongruent and congruent trials. The results suggest that the induced negative emotion influenced the Simon effect at the late stage of the cognitive process, and the P300 latency could be considered as the reference measure. These findings may be beneficial to researches in psychology and industrial engineering in the future.

  6. Testing Chern-Simons modified gravity with orbiting superconductive gravity gradiometers --- The non-dynamical formulation

    CERN Document Server

    Qiang, Li-E

    2015-01-01

    High precision Superconductivity Gravity Gradiometers (SGG) are powerful tools for relativistic experiments. In this paper, we work out the tidal signals in non-dynamical Chern-Simons modified gravity, which could be measured by orbiting SGGs around Earth. We find that, with proper orientations of multi-axes SGGs, the tidal signals from the Chern-Simons modification can be isolated in the combined data of different axes. Furthermore, for three-axes SGGs, such combined data is the trace of the total tidal matrix, which is invariant under the rotations of SGG axes and thus free from axis pointing errors. Following nearly circular orbits, the tests of the parity-violating Chern-Simons modification and the measurements of the gravitomagnetic sector in parity-conserving metric theories can be carried out independently in the same time. A first step analysis on noise sources is also included.

    We derive formulas for the classical Chern-Simons invariant of irreducible SU(n)-flat connections on negatively curved locally symmetric three-manifolds. We determine the condition for which the theory remains consistent (with basic physical principles). We show that a connection between holomorphic values of Selberg-type functions at point zero, associated with R-torsion of the flat bundle, and twisted Dirac operators acting on negatively curved manifolds, can be interpreted by means of the Chern-Simons invariant. On the basis of the Labastida-Marino-Ooguri-Vafa conjecture we analyze a representation of the Chern-Simons quantum partition function (as a generating series of quantum group invariants) in the form of an infinite product weighted by S-functions and Selberg-type functions. We consider the case of links and a knot and use the Rogers approach to discover certain symmetry and modular form identities. (orig.)

    Full Text Available This paper discusses an extended version of the Hawkins and Simon condition which constitutes a synthetic formulation of the mathematical properties that viable economies must satisfy in single production models. The new version is implicit in the economic interpretations offered by them of the Hawkins and Simon condition, once a correction is introduced in one of those interpretations. Moreover, the paper details the meaning of the extended version following the interpretation of the original version proposed by Dorfman, Samuelson, and Solow. It also introduces a characteristic property of indecomposable matrices that has not previously been published.

    2010-09-01

    Full Text Available This paper discusses Herbert A. Simon's conception of rationality in two of its principal general definitions: bounded rationality and procedural rationality. It argues that the latter is the one that better synthesizes the author's view about rational behavior and that the former fills mainly a critical function. They are complementarily used by Simon in this sense. In spite of that, it is argued that it is the low degree of specificity of the concept of bounded rationality one of the reasons for its relatively greater success.

    Full Text Available Introduction: Alveolar bone resorption is a significant clinical problem. Bone loss in third molar region following extraction or surgical removal not only leads to periodontal problems in second molar region but also it may lead to some serious problems like increased incidence of angle fractures. In order to reduce the risks following third molar surgery, the socket should be augmented with bone grafts. In recent days guided tissue regeneration is the most accepted and successful technique followed many authors and its efficacy has been proved. Materials and Methods: Based upon our clinical experience, the use of bio absorbable collagen wound dressing such as CollaPlugTN has achieved quick healing and more primary wound coverage. Amongst the graft materials collagen is preferable due to its high biocompatibility and hemostatic ability. This study was done to assess the regeneration of bone in the extracted third molar sockets using xenograft (CollaPlugTN-Zimmer which was compared with the normal healing on the contra lateral side. The assessment was done to analyze post-operative healing complications and to compare the bone density formed between control site and implant site radiologically. Conclusion: On this basis of this study, the use of collaplugTN appears to be beneficial to the patient in postoperative wound healing and also for better bone formation. The use of this material was advantageous because of its simplicity of application cost effectiveness and availability. There is enhanced wound healing and early bone formation.

  17. [Hermann Simon--reformer of psychiatry, social Darwinist, and National Socialist?].

    2002-11-01

    Hermann Simon (1867-1947) was shaped in his psychiatric thinking and views of society by the German empire. He showed a strongly conservative attitude and thought in ethnic-nationalistic terms. Beginning in 1905 and drawing on practical experience, he developed the concept of a "more active therapy." Simon perceived patients in a holistic way, regarding them not so much as sick people but as fellow men. He believed in the ability of a healthy personality to practice responsible and "well ordered self determination." Thus he defined the role of the doctor in a new way. Within Germany as well as internationally, active therapy was well-received, especially because of its positive effect on the atmosphere within asylums. In the context of reform of so-called open care during the Weimar epoch, Simon's approach was perceived in a new way because it allowed individual views of each patient, enabling assessment of the ability to work and chances for release. Simon himself set his concept in a "biological" and psychological context, based on his own biologistic and social Darwinistic world view. This view was open for eugenic, racial hygienic concepts, and fundamental criticism of welfare policy. It was only a short step from this conservative tenor, understanding of the state, and biologistic thinking to his open acclaim of Hitler and National Socialist (Nazi) racist policy.

  7. The Origin of Chern-Simons Modified Gravity from an 11 + 3-Dimensional Manifold

    Directory of Open Access Journals (Sweden)

    J. A. Helayël-Neto

    2017-01-01

    Full Text Available It is our aim to show that the Chern-Simons terms of modified gravity can be understood as generated by the addition of a 3-dimensional algebraic manifold to an initial 11-dimensional space-time manifold; this builds up an 11+3-dimensional space-time. In this system, firstly, some fields living in the bulk join the fields that live on the 11-dimensional manifold, so that the rank of the gauge fields exceeds the dimension of the algebra; consequently, there emerges an anomaly. To solve this problem, another 11-dimensional manifold is included in the 11+3-dimensional space-time, and it interacts with the initial manifold by exchanging Chern-Simon fields. This mechanism is able to remove the anomaly. Chern-Simons terms actually produce an extra manifold in the pair of 11-dimensional manifolds of the 11+3-space-time. Summing up the topology of both the 11-dimensional manifolds and the topology of the exchanged Chern-Simons manifold in the bulk, we conclude that the total topology shrinks to one, which is in agreement with the main idea of the Big Bang theory.

  8. Gauge symmetries and holographic anomalies of Chern-Simons and transgression AdS gravity

    2015-04-20

    We review the issue of gauge and gravitational anomalies with backgrounds, offering a new outlook on some aspects of these questions. We compute the holographic anomalies of hypothetical theories dual, in the sense of the AdS-CFT correspondence, to Chern-Simons AdS gravity. Those anomalies are either gauge anomalies, associated to the AdS gauge group of the theory, or diffeomorphism anomalies, with each kind related to the other. AdS gauge anomalies include Weyl, Lorentz (gravitational) and gauge translations while diffeomorphism anomalies include gravitational and Weyl (or scale) anomalies. Our results therefore go beyond previous investigations on Chern-Simons AdS gravity holograpic anomalies, that dealt only with Weyl anomalies. Furthermore, our calculations were done allowing a non vanishing torsion, unlike previous works that considered only the zero torsion, or metric, case. As a result of using suitable action principles for Chern-Simons AdS gravity, coming from Transgression forms, we obtain finite results without the need for further regularization. Our results are of potential interest for Lovelock gravity theories, as it has been shown that the boundary terms dictated by the transgressions for Chern-Simons gravity are also suitable to regularize Lovelock theories. The Wess-Zumino consistency condition ensures that anomalies of the generic form computed here should appear for these and other theories.

Forty-eight elderly adults and 45 young adults were assigned to three groups and performed a cognitive control task (Simon task, which was followed by 3 different manipulations of social priming (i.e., thinking about an 82 year-old person: 1 negative--characterized by poor cognitive abilities, 2 neutral--characterized by acts irrelevant to cognitive abilities, and 3 positive--excellent cognitive abilities. After the manipulation, the Simon task was performed again. Results showed improvement in cognitive control effects in seniors after the positive manipulation, indicated by a significant decrease in the magnitude of the Simon and interference effects, but not after the neutral and negative manipulations. Furthermore, a healthy pattern of sequential effect (Gratton that was absent before the manipulation in all 3 groups appeared after the positive manipulation. Namely, the Simon effect was only present after congruent but not after incongruent trials for the positive manipulation group. No influence of manipulations was found in young adults. These meaningful results were replicated in a second experiment and suggest a decrease in conflict interference resulting from positive cognitive state priming. Our study provides evidence that an implicit social concept of a positive cognitive condition in old age can affect the control process of the elderly and improve cognitive abilities.

  19. Anticipatory regulation of action control in a Simon task: Behavioral, electrophysiological and fMRI correlates

    Full Text Available With the present study we investigated cue-induced preparation in a Simon task and measured electroencephalogram and functional magnetic resonance imaging (fMRI data in two within-subjects sessions. Cues informed either about the upcoming 1 spatial stimulus-response compatibility (rule cues or 2 the stimulus location (position cues, or 3 were non-informative. Only rule cues allowed anticipating the upcoming compatibility condition. Position cues allowed anticipation of the upcoming location of the Simon stimulus but not its compatibility condition. Rule cues elicited fastest and most accurate performance for both compatible and incompatible trials. The contingent negative variation (CNV in the event-related brain potential (ERP of the cue-target interval is an index of anticipatory preparation and was magnified after rule cues. The N2 in the post-target ERP as a measure of online action control was reduced in Simon trials after rule cues. Although compatible trials were faster than incompatible trials in all cue conditions only non-informative cues revealed a compatibility effect in additional indicators of Simon task conflict like accuracy and the N2. We thus conclude that rule cues induced anticipatory re-coding of the Simon task that did not involve cognitive conflict anymore. FMRI revealed that rule cues yielded more activation of the left rostral, dorsal, and ventral prefrontal cortex as well as the pre-SMA as compared to POS and NON cues. Pre-SMA and ventrolateral prefrontal activation after rule cues correlated with the effective use of rule cues in behavioral performance. Position cues induced a smaller CNV effect and exhibited less prefrontal and pre-SMA contributions in fMRI. Our data point to the importance to disentangle different anticipatory adjustments that might also include the prevention of upcoming conflict via task re-coding.

  20. The carry-over effect of competition in task-sharing: evidence from the joint Simon task.

    Directory of Open Access Journals (Sweden)

    Cristina Iani

    Full Text Available The Simon effect, that is the advantage of the spatial correspondence between stimulus and response locations when stimulus location is a task-irrelevant dimension, occurs even when the task is performed together by two participants, each performing a go/no-go task. Previous studies showed that this joint Simon effect, considered by some authors as a measure of self-other integration, does not emerge when during task performance co-actors are required to compete. The present study investigated whether and for how long competition experienced during joint performance of one task can affect performance in a following joint Simon task. In two experiments, we required pairs of participants to perform together a joint Simon task, before and after jointly performing together an unrelated non-spatial task (the Eriksen flanker task. In Experiment 1, participants always performed the joint Simon task under neutral instructions, before and after performing the joint flanker task in which they were explicitly required either to cooperate with (i.e., cooperative condition or to compete against a co-actor (i.e., competitive condition. In Experiment 2, they were required to compete during the joint flanker task and to cooperate during the subsequent joint Simon task. Competition experienced in one task affected the way the subsequent joint task was performed, as revealed by the lack of the joint Simon effect, even though, during the Simon task participants were not required to compete (Experiment 1. However, prior competition no longer affected subsequent performance if a new goal that created positive interdependence between the two agents was introduced (Experiment 2. These results suggest that the emergence of the joint Simon effect is significantly influenced by how the goals of the co-acting individuals are related, with the effect of competition extending beyond the specific competitive setting and affecting subsequent interactions.

    2014-07-11

    Recently, it was shown that the spectrum of anomalous dimensions and other important observables in planar N=4 supersymmetric Yang-Mills theory are encoded into a simple nonlinear Riemann-Hilbert problem: the Pμ system or quantum spectral curve. In this Letter, we extend this formulation to the N=6 supersymmetric Chern-Simons theory introduced by Aharony, Bergman, Jafferis, and Maldacena. This may be an important step towards the exact determination of the interpolating function h(λ) characterizing the integrability of this model. We also discuss a surprising relation between the quantum spectral curves for the N=4 supersymmetric Yang-Mills theory and the N=6 supersymmetric Chern-Simons theory considered here.

  4. Nuclear dawn F. E. Simon and the race for atomic weapons in World War II

    CERN Document Server

    McRae, Kenneth D

    2014-01-01

    This book provides a rounded biography of Franz (later Sir Francis) Simon, his early life in Germany, his move to Oxford in 1933, and his experimental contributions to low temperature physics approximating absolute zero. After 1939 he switched his research to nuclear physics, and is credited with solving the problem of uranium isotope separation by gaseous diffusion for the British nuclear programme Tube Alloys. The volume is distinctive for its inclusion of source materials not available to previous researchers, such as Simon's diary and his correspondence with his wife, and for a fresh, well-informed insider voice on the five-power nuclear rivalry of the war years. The work also draws on a relatively mature nuclear literature to attempt a comparison and evaluation of the five nuclear rivals in wider political and military context, and to identify the factors, or groups of factors, that can explain the results.

  5. Computation of Lickorish's Three Manifold Invariant Using Chern-Simons Theory

    Science.gov (United States)

    Ramadevi, P.; Naik, Swatee

    It is well known that any three-manifold can be obtained by surgery on a framed link in S3. Lickorish gave an elementary proof for the existence of the three-manifold invariant of Witten using a framed link description of the manifold and the formalisation of the bracket polynomial as the Temperley-Lieb Algebra. Kaul determined a three-manifold invariant from link polynomials in SU(2) Chern-Simons theory. Lickorish's formula for the invariant involves computation of bracket polynomials of several cables of the link. We describe an easier way of obtaining the bracket polynomial of a cable using representation theory of composite braiding in SU(2) Chern-Simons theory. We prove that the cabling corresponds to taking tensor products of fundamental representations of SU(2). This enables us to verify that the two apparently distinct three-manifold invariants are equivalent for a specific relation of the polynomial variables.

  6. I-Love-Q relations for neutron stars in dynamical Chern Simons gravity

    Neutron stars are ideal to probe, not only nuclear physics, but also strong-field gravity. Approximate universal relations insensitive to the star’s internal structure exist among certain observables and are useful in testing general relativity, as they project out the uncertainties in the equation of state. One such set of universal relations between the moment of inertia (I), the tidal Love number and the quadrupole moment (Q) has been studied both in general relativity and in modified theories. In this paper, we study the relations in dynamical Chern–Simons gravity, a well-motivated, parity-violating effective field theory, extending previous work in various ways. First, we study how projected constraints on the theory using the I-Love relation depend on the measurement accuracy of I with radio observations and that of the Love number with gravitational-wave observations. Provided these quantities can be measured with future observations, we find that the latter could place bounds on dynamical Chern–Simons gravity that are six orders of magnitude stronger than current bounds. Second, we study the I–Q and Q-Love relations in this theory by constructing slowly-rotating neutron star solutions to quadratic order in spin. We find that the approximate universality continues to hold in dynamical Chern–Simons gravity, and in fact, it becomes stronger than in general relativity, although its existence depends on the normalization of the dimensional coupling constant of the theory. Finally, we study the variation of the eccentricity of isodensity contours inside a star and its relation to the degree of universality. We find that, in most cases, the eccentricity variation is smaller in dynamical Chern–Simons gravity than in general relativity, providing further support to the idea that the approximate self-similarity of isodensity contours is responsible for universality.

    In 1964, Simone de Beauvoir, arguably one of the greatest writers of 20th century Europe, published an account of the final 6 weeks of her mother's life. It is a beautifully written, raw, honest, and powerful evocation of that period from the viewpoint of a relative. Its themes are universal-love, ambivalence in family ties, loss, and bereavement. Given that the events preceded the modern palliative care movement, reflections are made on differences in medical practice since the book's publication.

    Cabra-García, Jimmy; Brescovit, Antonio D

    2016-01-27

    A taxonomic revision and phylogenetic analysis of the spider genus Glenognatha Simon, 1887 is presented. This analysis is based on a data set including 24 Glenognatha species plus eight outgroups representing three related tetragnathine genera and one metaine as the root. These taxa were scored for 78 morphological characters. Parsimony was used as the optimality criterion and a sensitivity analysis was performed using different character weighting concavities. Seven unambiguous synapomorphies support the monophyly of Glenognatha. Some internal clades within the genus are well-supported and its relationships are discussed. Glenognatha as recovered includes 27 species, four of them only known from males. A species identification key and distribution maps are provided for all. New morphological data are also presented for thirteen previously described species. Glenognatha has a broad distribution occupying the Neartic, Afrotropic, Indo-Malaya, Oceania and Paleartic regions, but is more diverse in the Neotropics. The following eleven new species are described: G. vivianae n. sp., G. caaguara n. sp., G. boraceia n. sp. and G. timbira n. sp. from southeast Brazil, G. caparu n. sp., G. januari n. sp. and G. camisea n. sp. from the Amazonian region, G. mendezi n. sp., G. florezi n. sp. and G. patriceae n. sp. from northern Andes and G. gouldi n. sp. from Southern United States and central Mexico. Females of G. minuta Banks, 1898, G. gaujoni Simon, 1895 and G. gloriae (Petrunkevitch, 1930) and males of G. globosa (Petrunkevitch, 1925) and G. hirsutissima (Berland, 1935) are described for the first time. Three new combinations are proposed in congruence with the phylogenetic results: G. argyrostilba (O. P.-Cambridge, 1876) n. comb., G. dentata (Zhu & Wen, 1978) n. comb. and G. tangi (Zhu, Song & Zhang, 2003) n. comb., all previously included in Dyschiriognatha Simon, 1893.

    Kauffman, Louis H.

    This paper is an exposition of the relationship between Witten's Chern-Simons functional integral and the theory of Vassiliev invariants of knots and links in three-dimensional space. We conceptualize the functional integral in terms of equivalence classes of functionals of gauge fields and we do not use measure theory. This approach makes it possible to discuss the mathematics intrinsic to the functional integral rigorously and without functional integration. Applications to loop quantum gravity are discussed.

    We study the dynamics of [ital N] nonrelativistic point particles interacting with Chern-Simons gauge field in 2+1 dimensions. The model is canonically quantized in the Hamiltonian formalism without any gauge fixing. While the first quantization of the particles is retained, the fields are second quantized. The generators of the Galilean transformations are defined and shown to satisfy the requisite algebra. Fractional spin is computed, which is related to the number of particles.

  14. Sequential Modulations in a Combined Horizontal and Vertical Simon Task: Is There ERP Evidence for Feature Integration Effects?

    In the Simon task, participants respond faster when the task-irrelevant stimulus position and the response position are corresponding, for example on the same side, compared to when they have a non-corresponding relation. Interestingly, this Simon effect is reduced after non-corresponding trials. Such sequential effects can be explained in terms of a more focused processing of the relevant stimulus dimension due to increased cognitive control, which transfers from the previous non-corresponding trial (conflict adaptation effects). Alternatively, sequential modulations of the Simon effect can also be due to the degree of trial-to-trial repetitions and alternations of task features, which is confounded with the correspondence sequence (feature integration effects). In the present study, we used a spatially two-dimensional Simon task with vertical response keys to examine the contribution of adaptive cognitive control and feature integration processes to the sequential modulation of the Simon effect. The two-dimensional Simon task creates correspondences in the vertical as well as in the horizontal dimension. A trial-by-trial alternation of the spatial dimension, for example from a vertical to a horizontal stimulus presentation, generates a subset containing no complete repetitions of task features, but only complete alternations and partial repetitions, which are equally distributed over all correspondence sequences. In line with the assumed feature integration effects, we found sequential modulations of the Simon effect only when the spatial dimension repeated. At least for the horizontal dimension, this pattern was confirmed by the parietal P3b, an event-related potential that is assumed to reflect stimulus-response link processes. Contrary to conflict adaptation effects, cognitive control, measured by the fronto-central N2 component of the EEG, was not sequentially modulated. Overall, our data provide behavioral as well as electrophysiological evidence for feature

  15. Supersymmetry, quantum gauge anomalies and generalized Chern-Simons terms in chiral gauge theory

    Schmidt, Torsten

    2009-05-13

    The purpose of this thesis is to investigate the interplay of anomaly cancellation and generalized Chern-Simons terms in four-dimensional chiral gauge theory. We start with a detailed discussion of generalized Chern-Simons terms with the canellation of anomalies via the Green-Schwarz mechanism. With this at hand, we investigate the situation in general N=1 supersymmetric field theories with generalized Chern-Simons terms. Two simple consistency conditions are shown to encode strong constraints on the allowed anomalies for different types of gauge groups. In one major part of this thesis we are going to display to what extent one has to modify the existing formalism in order to allow for the cancellation of quantum gauge anomalies via the Green-Schwarz mechanism. At the end of this thesis we comment on a puzzle in the literature on supersymmetric field theories with massive tensor fields. The potential contains a term that does not arise from eliminating an auxiliary field. We clarify the origin of this term and display the relation to standard D-term potential. In an appendix it is explicitly shown how these low energy effective actions might be connected to the formulation of four-dimensional gauge theories discussed at earlier stages of this thesis.

    Allemandi, G; Raiteri, M

    2003-01-01

    We try to give hereafter an answer to some open questions about the definition of conserved quantities in Chern-Simons theory, with particular reference to Chern-Simons AdS sub 3 gravity. Our attention is focused on the problem of global covariance and gauge invariance of the variation of Noether charges. A theory which satisfies the principle of covariance on each step of its construction is developed, starting from a gauge invariant Chern-Simons Lagrangian and using a recipe developed by Allemandi et al (2002 Class. Quantum Grav. 19 2633-55, 237-58) to calculate the variation of conserved quantities. The problem of giving a mathematical well-defined expression for the infinitesimal generators of symmetries is pointed out and it is shown that the generalized Kosmann lift of spacetime vector fields leads to the expected numerical values for the conserved quantities when the solution corresponds to the BTZ black hole. The fist law of black-hole mechanics for the BTZ solution is then proved and the transition b...

  17. Efficient classical simulation of the Deutsch-Jozsa and Simon's algorithms

    2017-09-01

    A long-standing aim of quantum information research is to understand what gives quantum computers their advantage. This requires separating problems that need genuinely quantum resources from those for which classical resources are enough. Two examples of quantum speed-up are the Deutsch-Jozsa and Simon's problem, both efficiently solvable on a quantum Turing machine, and both believed to lack efficient classical solutions. Here we present a framework that can simulate both quantum algorithms efficiently, solving the Deutsch-Jozsa problem with probability 1 using only one oracle query, and Simon's problem using linearly many oracle queries, just as expected of an ideal quantum computer. The presented simulation framework is in turn efficiently simulatable in a classical probabilistic Turing machine. This shows that the Deutsch-Jozsa and Simon's problem do not require any genuinely quantum resources, and that the quantum algorithms show no speed-up when compared with their corresponding classical simulation. Finally, this gives insight into what properties are needed in the two algorithms and calls for further study of oracle separation between quantum and classical computation.

  18. The Age of Miracle and Wonders: Paul Simon and the Changing American Dream.

    Science.gov (United States)

    Fuchsman, Ken

    2016-01-01

    The American dream altered. In the 19th century, it was focused on male success in the marketplace. With the rise of the consumer culture, ideals changed. Women were brought in, as companionate marriage, home ownership, and a successful domestic life with children became central in American life. Since the mid-sixties, singer-songwriter Paul Simon has been writing songs reflecting these changes. He has two songs with America in the title, and is one of the few rock stars that write extensively about marriage and parenting. He also writes about love as romance, with a spouse, and towards offspring. Simon too composes songs about affluence, technology, and what brings happiness and joy. His work illuminates the United States in what he says is "the age's most uncertain hour." He believed that affluence was a key to our fulfillment. The changes in American life since the 1970s, show that much of what was held as ideal, has been through troubled times. We can gain insight into the fate of the American dream through Simon's songs.

    2017-03-01

    We consider rotating black hole solutions in five-dimensional Einstein-Maxwell-Chern-Simons theory with a negative cosmological constant and a generic value of the Chern-Simons coupling constant λ . Using both analytical and numerical techniques, we focus on cohomogeneity-1 configurations, with two equal-magnitude angular momenta, which approach at infinity a globally anti-de Sitter background. We find that the generic solutions share a number of basic properties with the known Cvetič, Lü, and Pope black holes which have λ =1 . New features occur as well; for example, when the Chern-Simons coupling constant exceeds a critical value, the solutions are no longer uniquely determined by their global charges. Moreover, the black holes possess radial excitations which can be labelled by the node number of the magnetic gauge potential function. Solutions with small values of λ possess other distinct features. For instance, the extremal black holes there form two disconnected branches, while not all near-horizon solutions are associated with global solutions.

  1. Processing irrelevant location information: practice and transfer effects in a Simon task.

    Directory of Open Access Journals (Sweden)

    Dan B Welch

    Full Text Available How humans produce cognitively driven fine motor movements is a question of fundamental importance in how we interact with the world around us. For example, we are exposed to a constant stream of information and we must select the information that is most relevant by which to guide our actions. In the present study, we employed a well-known behavioral assay called the Simon task to better understand how humans are able to learn to filter out irrelevant information. We trained subjects for four days with a visual stimulus presented, alternately, in central and lateral locations. Subjects responded with one hand moving a joystick in either the left or right direction. They were instructed to ignore the irrelevant location information and respond based on color (e.g. red to the right and green to the left. On the fifth day, an additional testing session was conducted where the task changed and the subjects had to respond by shape (e.g. triangle to the right and rectangle to the left. They were instructed to ignore the color and location, and respond based solely on the task relevant shape. We found that the magnitude of the Simon effect decreases with training, however it returns in the first few trials after a break. Furthermore, task-defined associations between response direction and color did not significantly affect the Simon effect based on shape, and no significant associative learning from the specific stimulus-response features was found for the centrally located stimuli. We discuss how these results are consistent with a model involving route suppression/gating of the irrelevant location information. Much of the learning seems to be driven by subjects learning to suppress irrelevant location information, however, this seems to be an active inhibition process that requires a few trials of experience to engage.

    Throughout the 19th century, yellow fever was the scourge of southern coastal cities. Because of primitive diagnostic tools, differential diagnosis during epidemics was often difficult. Many patients were diagnosed with "malarial fever," breakbone fever, "the prevailing fever," and "mild yellow fever," to name a few. Dr. Manning Simon's opportunity to study an almost "pure" epidemic of yellow fever among an "unacclimated" population was a breakthrough in diagnostic medicine. Fortunately, his findings were not to be needed again in South Carolina, since this was the last outbreak of yellow fever in the state.

    Dynamical Chern-Simons gravity cannot be strongly constrained with current experiments because it reduces to general relativity in the weak-field limit. This theory, however, introduces modifications in the nonlinear, dynamical regime, and thus it could be greatly constrained with gravitational waves from the late inspiral of black-hole binaries. We complete the first self-consistent calculation of such gravitational waves in this theory. For favorable spin orientations, advanced ground-based detectors may improve existing solar system constraints by 6 orders of magnitude.

    The males of Tobias caudatus Mello-Leitão, 1929 and Tobias pustulosus Simon, 1929 are described for the first time, females are redescribed and both sexes are illustrated. New distribution records are presented for both species. Tobias monstruosus Mello-Leitão, 1929 is considered a junior synonym of T. pustulosus. The types of Tobias albovittatus Caporiacco, 1954, and Tobias gradiens Mello-Leitão, 1929 are lost, and Tobias albicans Mello-Leitão, 1929 and Tobias corticatus Mello-Leitão, 1917 are known only from poorly preserved specimens, thus they all are considered nomina dubia.

    We explicitly carry out the renormalization of non-abelian Chern-Simons field theories with matter in (2 + 1) dimensions. All the renormalization constants are calculated to the leading two-loop order both in terms of component fields and N = 1 superfields for the fundamental representation of the SU( n), Sp( n) and SO( n) groups. Renormalization-group fixed points are found, and their stability properties are examined. It is shown that the N = 2 supersymmetry is realized as an infrared fixed-point solution, where the ultraviolet divergencies cancel.

In contrast to the Carroll-Field-Jackiw (CFE model [2] these systems are relativistically invariant and include the CFJ model as a particular sector.Using the InNonNu-Wigner contraction a Galilei-invariant non-relativistic limit of the systems is found, which makes possible to find a Galilean formulation of the CFJ model.

    We find soliton solutions of the noncommutative Maxwell-Chern-Simons theory confined to a finite quantum Hall droplet. The solitons are exactly as hypothesized elsewhere. We also find new variations on these solitons. We compute their flux and their energies. The model we consider is directly related to the model proposed by Polychronakos and also studied by Hellerman and Van Raamsdonk. They show that this model is equivalent to the Laughlin theory of the quantum Hall effect. Our solitons should be thought of as classical vortex configurations of this theory.

    In these lectures, I give a pedagogical presentation of some of the recent progress in supersymmetric Chern-Simons-matter theories, coming from the use of localization and matrix model techniques. The goal is to provide a simple derivation of the exact interpolating function for the free energy of ABJM theory on the three-sphere, which implies in particular the N{sup 3/2} behavior at strong coupling. I explain in detail part of the background needed to understand this derivation, like holographic renormalization, localization of path integrals and large N techniques in matrix models.

    The Simon task is one of the most prominent interference tasks and has been extensively studied in experimental psychology and cognitive neuroscience. Despite years of research, the underlying mechanism driving the phenomenon and its temporal dynamics are still disputed. Within the framework of the review, we adopt a model-based cognitive neuroscience approach. We first go over key findings in the literature of the Simon task, discuss competing qualitative cognitive theories and the difficulty of testing them empirically. We then introduce sequential sampling models, a particular class of mathematical cognitive process models. Finally, we argue that the brain architecture accountable for the processing of spatial ('where') and non-spatial ('what') information, could constrain these models. We conclude that there is a clear need to bridge neural and behavioral measures, and that mathematical cognitive models may facilitate the construction of this bridge and work towards revealing the underlying mechanisms of the Simon effect.

    The Clean Air Act, as revised in 1992, has spurred the development of flue gas desulfurization (FGD) technologies that have resulted in large volumes of wet scrubber sludges. In general, these sludges must be dewatered, chemically treated, and disposed of in landfills. Disposal is an expensive and environmentally questionable process for which suitable alternatives must be found. Wet scrubbing with magnesium (Mg)-enhanced lime has emerged as an efficient, cost effective technology for SO2 removal. When combined with an appropriate oxidation system, the wet scrubber sludge can be used to produce gypsum (CaSO4-2H2O) and magnesium hydroxide [Mg(OH)2] of sufficient purity for beneficial re-use. Product value generally increases with purity of the by-product(s). The pilot plant at the CINERGY Zimmer Station near Cincinnati produces gypsum by products that can be formulated to contain varying amounts of Mg(OH)2. Such materials may have agricultural value as soil conditioners, liming agents and sources of plant nutrients (Ca, Mg, S). This report describes a greenhouse study designed to evaluate by-product gypsum and Mg gypsum from the Zimmer Station pilot plant as amendments for improving the quality of agricultural soils and mine spoils that are currently unproductive because of phytotoxic conditions related to acidity and high levels of toxic dissolved aluminum (Al). In particular, the technical literature contains evidence to suggest that gypsum may be more effective than agricultural limestone in modifying soil chemical conditions below the immediate zone of application. Representative samples of by-product gypsum and Mg(OH)2 from the Zimmer Station were initially characterized. The gypsum was of high chemical purity and consisted of well crystalline, lath-shaped particles of low specific surface area. By contrast, the by-product Mg(OH)2 was a high surface area material (50 m2 g

    The general procedure for obtaining explicit expressions for all cohomologies of Berkovits' operator is suggested. It is demonstrated that calculation of BV integral for the classical Chern-Simons-like theory (Witten's OSFT-like theory) reproduces BV version of two-dimensional gauge model at the level of effective action. This model contains gauge field, scalars, fermions and some other fields. We prove that this model is an example of 'singular' point from the perspective of the suggested method for cohomology evaluation. For arbitrary 'regular' point the same technique results in AKSZ (Alexandrov, Kontsevich, Schwarz, Zaboronsky) version of Chern-Simons theory (BF theory) in accord with [N.

    Yagi, Kent; Yunes, Nicolas; Tanaka, Takahiro

    2013-01-01

    We study isolated and binary neutron stars in dynamical Chern-Simons gravity. This theory modifies the Einstein-Hilbert action through the introduction of a dynamical scalar field coupled to the Pontryagin density. We here treat this theory as an effective model, working to leading order in the Chern-Simons coupling. We first construct isolated neutron star solutions in the slow-rotation expansion to quadratic order in spin. We find that isolated neutron stars acquire a scalar dipole charge that corrects its spin angular momentum to linear order in spin and corrects its mass and quadrupole moment to quadratic order in spin, as measured by an observer at spatial infinity. We then consider neutron stars binaries that are widely separated and solve for their orbital evolution in this modified theory. We find that the evolution of post-Keplerian parameters is modified, with the rate of periastron advance being the dominant correction at first post-Newtonian order. We conclude by applying these results to observed...

    Tonic neck reflexes described in 1921 by Magnus and deKlejn in animals and men were studied in hemiplegic patients who were mainly victims of WWI by Arthur Simons, a neurologist in Berlin and coworker of Hermann Oppenheim. The effect of the asymmetric neck reflexes after head rotation was restricted to the paralyzed side: tonus (spasms) of extension and adduction during mid-position of the head or head version to the paralyzed side; flexion tonus and abduction during head version to the non-paralyzed side; and flexion tonus (spasms) of the paralyzed limbs during flexion of the head and extension spasms by head extension. More than this, hemiplegic "Mitbewegungen" or associated reactions (Walshe) were observed. They are elicited by conscious innervations of the unaffected side, e.g. by fist closure, and are increased or varied by head rotation, the tonic neck reflexes. They occurred in 25%. A film with Arthur Simons as examiner from the years 1916-1919 shows these nearly forgotten phenomena. Their everyday significance was already stressed in 1920, long before the rules of antispastic positions were defined by Bobath.

    We clarify the higher-dimensional origin of a class of dyonic gaugings of D=4  N=8 supergravity recently discovered, when the gauge group is chosen to be ISO(7). This dyonically gauged maximal supergravity arises from consistent truncation of massive IIA supergravity on S^6, and its magnetic coupling constant descends directly from the Romans mass. The critical points of the supergravity uplift to new four-dimensional anti-de Sitter space (AdS4) massive type IIA vacua. We identify the corresponding three-dimensional conformal field theory (CFT3) duals as super-Chern-Simons-matter theories with simple gauge group SU(N) and level k given by the Romans mass. In particular, we find a critical point that uplifts to the first explicit N=2 AdS4 massive IIA background. We compute its free energy and that of the candidate dual Chern-Simons theory by localization to a solvable matrix model, and find perfect agreement. This provides the first AdS4/CFT3 precision match in massive type IIA string theory.

    The principles and concepts of the profession of urbanism are presented, and the experience of the University Simon Bolivar in the field is summarized. The perspective of urbanism is that the chaos and poor quality of life in many Latin American metropolitan areas are problems that can be solved through creation of an urban authority that would reconcile urban growth with quality of space and rationality of process. The field of urbanism was dominated for its first century by architects, engineers, and hygienists. In the 1960s, undergraduate programs were designed in town planning, city planning, and urban planning in Great Britain and the US to offer interdisciplinary training, with greater emphasis on the social sciences, mathematical methods of modeling, and distinctness from architecture. The university Simon Bolivar created an urbanism program in 1975, which like other Latin American programs gave somewhat greater emphasis to training in spatial design than did the US and British programs. The program has continued to be based on a systemic focus and the union of design and management in urban planning practice. The object of study has been redefined to encompass not just the city but the general environment. The program in its first 20 years has had internal problems such as the tendency of some professors to over-emphasize their own disciplines and insufficient training in management techniques, and external problems such as the negative societal image of urbanism and urbanization. Reinforcement of the computer capabilities and faculty should enable the program to meet future challenges.

    We propose a generalization of Chiral Gravity, which follows from considering a Chern-Simons action for the spin connection with anti-symmetric contorsion. The theory corresponds to Topologically Massive Gravity at the chiral point non-minimally coupled to an additional scalar mode that gathers the torsion degree of freedom. In this setup, the effective cosmological constant (the inverse of the curvature radius of maximally symmetric solutions) is either negative or zero, and it enters as an integration constant associated to the value of the contorsion at infinity. We explain how this is not in conflict with the Zamolodchikov’s c-theorem holding in the dual boundary theory. In fact, we conjecture that the theory formulated about three-dimensional Anti-de Sitter space is dual to a two-dimensional conformal field theory whose right- and left-moving central charges are given by c{sub R}=24k and c{sub L}=0, respectively, being k the level of the Chern-Simons action. We study the classical theory both at the linear and non-linear level. In particular, we show how Chiral Gravity is included as a special sector. In addition, the theory has other sectors, which we explore; we exhibit analytic exact solutions that are not solutions of Topologically Massive Gravity (and, consequently, neither of General Relativity) and still satisfy Brown-Henneaux asymptotically AdS{sub 3} boundary conditions.

    We report an experimental demonstration of a one-way implementation of a quantum algorithm solving Simon's problem-a black-box period-finding problem that has an exponential gap between the classical and quantum runtime. Using an all-optical setup and modifying the bases of single-qubit measurements on a five-qubit cluster state, key representative functions of the logical two-qubit version's black box can be queried and solved. To the best of our knowledge, this work represents the first experimental realization of the quantum algorithm solving Simon's problem. The experimental results are in excellent agreement with the theoretical model, demonstrating the successful performance of the algorithm. With a view to scaling up to larger numbers of qubits, we analyze the resource requirements for an n-qubit version. This work helps highlight how one-way quantum computing provides a practical route to experimentally investigating the quantum-classical gap in the query complexity model.

  3. Pure Yang-mills, Noncommutative Chern-simons And Noncommutative Quantum Mechanics: A Hamiltonian Approach

    CERN Document Server

    2005-01-01

    This thesis addresses three topics: calculation of the invariant measure for the pure Yang-Mills configuration space in (3 + 1) dimensions, Hamiltonian analysis of the pure Chern-Simons theory on the noncommutative plane and noncommutative quantum mechanics in the presence of singular potentials. In Chapter 1 we consider a gauge-invariant Hamiltonian analysis for Yang-Mills theories in three spatial dimensions. The gauge potentials are parameterized in terms of a matrix variable which facilitates the elimination of the gauge degrees of freedom. We develop an approximate calculation of the volume element on the gauge-invariant configuration space. We also make a rough estimate of the ratio of 0++ glueball mass and the square root of string tension by comparison with (2 + 1)-dimensional Yang-Mills theory. In Chapter 2 the Hamiltonian analysis of the pure Chern- Simons theory on the noncommutative plane is performed. We use the techniques of geometric quantization to show that the classical reduced phase space o...

    We study the entanglement entropy between (possibly distinct) topological phases across an interface using an Abelian Chern-Simons description with topological boundary conditions (TBCs) at the interface. From a microscopic point of view, these TBCs correspond to turning on particular gapping interactions between the edge modes across the interface. However, in studying entanglement in the continuum Chern-Simons description, we must confront the problem of non-factorization of the Hilbert space, which is a standard property of gauge theories. We carefully define the entanglement entropy by using an extended Hilbert space construction directly in the continuum theory. We show how a given TBC isolates a corresponding gauge invariant state in the extended Hilbert space, and hence compute the resulting entanglement entropy. We find that the sub-leading correction to the area law remains universal, but depends on the choice of topological boundary conditions. This agrees with the microscopic calculation of [1]. Additionally, we provide a replica path integral calculation for the entropy. In the case when the topological phases across the interface are taken to be identical, our construction gives a novel explanation of the equivalence between the left-right entanglement of (1+1)d Ishibashi states and the spatial entanglement of (2+1)d topological phases.

    Full Text Available Tasks for which people must act together to achieve a goal are a feature of daily life. The present study explored social influences on joint action using a Simon procedure for which participants (n=44 were confronted with a series of images of hands and asked to respond via button press whenever the index finger wore a ring of a certain colour (red or green regardless of pointing direction (left or right. In an initial joint condition they performed the task while sitting next to another person (friend or stranger who responded to the other colour. In a subsequent individual condition they repeated the task on their own; additionally, they completed self-report tests of empathy. Consistent with past research, participants reacted more quickly when the finger pointed towards them rather than their co-actor (the Simon Effect or SE. The effect remained robust when the co-actor was no longer present and was unaffected by degree of acquaintance; however, its magnitude was correlated positively with empathy only among friends. For friends, the SE was predicted by cognitive perspective taking when the co-actor was present and by propensity for fantasizing when the co-actor was absent. We discuss these findings in relation to social accounts (e.g., task co-representation and non-social accounts (e.g., referential coding of joint action.

    All species of Epicadus Simon, 1895 are reviewed and redescribed, including the previously unknown males of E. rubripes Mello-Leitão, 1924 and E. planus Mello-Leitão, 1932. A new diagnosis based on morphological characters is proposed for the genus. Three valid species of Epicadus are recognized: E. heterogaster (Guérin-Méneville, 1829); E. rubripes and E. planus. The following taxonomic changes are proposed: E. granulatus Banks, 1909 is considered incertae sedis, most likely belonging to a new genus; E. h. scholagriculae Piza, 1933 is considered a junior subjective synonym of E. heterogaster; E. pallidus Mello-Leitão, 1929 is considered a junior subjective synonym of E. rubripes Mello-Leitão, 1924; E. nigronotatus Mello-Leitão, 1940 is considered junior subjective synonym of E. planus Mello-Leitão, 1932. Species distributions were updated with new records in the Neotropics, including Bolivia, Colombia, Ecuador, Mexico, Panama, Paraguay, Peru and Venezuela, which makes Epicadus a genus of Neotropical distribution.

    Tonic neck reflexes were investigated by Rudolf Magnus and Adriaan de Kleijn in animals and men in 1912 and eventually by Arthur Simons, a neurologist in Berlin and coworker of Hermann Oppenheim. Simons studied these reflexes in hemiplegic patients, who were mainly victims of World War I. This work became his most important contribution and remained unsurpassed for many years. The film (Filmarchiv, Bundesarchiv [Film Archive, National Archive] Berlin) with Simons as an examiner shows 11 war casualties with brain lesions that occurred between 1916 and 1919. The injuries reveal asymmetric neck reflexes with "Mitbewegungen," that is, flexion or extension on the hemiplegic side. Mitbewegungen is identical with Francis Walshe's "associated reactions" caused by neck rotation and/or by cocontraction of the nonaffected extremities, for example, by closing of the fist (Walshe). The knowledge of the neck reflexes is important in acute neurology and in rehabilitation therapy of hemiplegics for antispastic positions. Simons' investigations were conducted in the early era of increasing use of cinematography in medical studies. The film had been nearly forgotten until its rediscovery in 2010.

    The Mt. Simon Formation, a basal Cambrian sandstone underlying the Illinois Basin in the Central US, is a target for underground storage and waste injection which require an assessment of geomechanical behavior. The range of depositional environments, from braided streams and minor eolean features in the lower Mt Simon, to tidally-influenced near- and on-shore sands in the upper Mt. Simon, yield a heterogeneous formation with a range in porosity, permeability, and mechanical properties. We examine the experimental deformational behavior of three distinct Mt. Simon lithofacies via axisymmetric compressional testing. Initial yielding is confirmed with acoustic emissions in many of the tests and failure envelopes are determined for each lithofacies. The evolution of (assumed) isotropic elastic moduli are examined during testing by use of unload-reload cycles, which permit the separation of total measured strains into elastic and plastic (permanent) strains. The upper Mt Simon samples deform largely elastically at stresses encountered in the Illinois Basin, with very little modulus degradation. The lower Mt. Simon facies are weaker and deform plastically, with varying amounts of modulus degradation. Results are interpreted via petrographic observation of textural contrasts. This range in constitutive response is captured up to failure with a phenomenological elasto-plasticity model. Essential aspects to describe observed behavior used in the model include non-associative plasticity, stress-invariant dependent failure, an elliptical cap surface capturing shear effects on pore collapse, kinematic and isotropic hardening, nonlinear elasticity and elastic-plastic coupling, among other features. Static moduli derived from laboratory tests are compared to dynamic moduli from wellbore log response which can allow experimental results and model to be extrapolated to Mt. Simon occurrences across the basin. This work was funded in part by the Center for Frontiers of Subsurface

  15. Exact solution of Chern-Simons-matter matrix models with characteristic/orthogonal polynomials

    We solve for finite N the matrix model of supersymmetric U(N) Chern-Simons theory coupled to N{sub f} fundamental and N{sub f} anti-fundamental chiral multiplets of R-charge 1/2 and of mass m, by identifying it with an average of inverse characteristic polynomials in a Stieltjes-Wigert ensemble. This requires the computation of the Cauchy transform of the Stieltjes-Wigert polynomials, which we carry out, finding a relationship with Mordell integrals, and hence with previous analytical results on the matrix model. The semiclassical limit of the model is expressed, for arbitrary N{sub f}, in terms of a single Hermite polynomial. This result also holds for more general matter content, involving matrix models with double-sine functions.

    The Mars-Simon tensor (MST), which, e.g., plays a crucial role to provide gauge invariant characterizations of the Kerr-NUT-(A)(dS) family, satisfies a Bianchi-like equation. In this paper, we analyze this equation in close analogy to the Bianchi equation, in particular it will be shown that the constraints are preserved supposing that a generalized Buchdahl condition holds. This permits the systematic construction of solutions to this equation in terms of a well-posed Cauchy problem. A particular emphasis lies on the asymptotic Cauchy problem, where data are prescribed on a space-like I (i.e., for ∧ > 0). In contrast to the Bianchi equation, the MST equation is of Fuchsian type at I , for which existence and uniqueness results are derived.

    We discuss the generalization of the NUT spacetime in General Relativity (GR) within the framework of the (dynamical) Einstein–Chern–Simons (ECS) theory with a massless scalar field. These configurations approach asymptotically the NUT spacetime and are characterized by the ‘electric’ and ‘magnetic’ mass parameters and a scalar ‘charge’. The solutions are found both analytically and numerically. The analytical approach is perturbative around the Einstein gravity background. Our results indicate that the ECS configurations share all basic properties of the NUT spacetime in GR. However, when considering the solutions inside the event horizon, we find that in contrast to the GR case, the spacetime curvature grows (apparently) without bound.

  20. Anomalies, Anomalous U(1)'s and generalized Chern-Simons terms

    2006-01-01

    A detailed analysis of anomalous U(1)'s and their effective couplings is performed both in field theory and string theory. It is motivated by the possible relevance of such couplings in particle physics, as well as a potential signal distinguishing string theory from other UV options. The most general anomaly related effective action is analyzed and parameterized. It contains Stuckelberg, axionic and Chern-Simons-like couplings. It is shown that such couplings are generically non-trivial in orientifold string vacua and are not in general fixed by anomalies. A similar analysis in quantum field theories provides similar couplings. The trilinear gauge boson couplings are also calculated and their phenomenological relevance is advocated. We do not find qualitative differences between string and field theory in this sector.

    We propose an extension of Vasiliev’s supertrace operation for the enveloping algebra of Wigner’s deformed oscillator algebra to the fractional spin algebra given in http://arxiv.org/abs/1312.5700. We provide a necessary and sufficient condition for the consistency of the supertrace, through the existence of a certain ground state projector. We build this projector and check its properties to the first two orders in the number operator and to all orders in the deformation parameter. We then find the relation between the gravitational and internal gauge couplings in the resulting unified three-dimensional Chern-Simons theory for Blencowe-Vasiliev higher spin gravity coupled to fractional spin fields and internal gauge potentials. We also examine the model for integer or half-integer fractional spins, where infinite dimensional ideals arise and decouple, leaving finite dimensional gauge algebras gl(2ℓ+1) or gl(ℓ|ℓ+1) and various real forms thereof.

    The two-point gauge correlation function in Yang–Mills–Chern–Simons theory in three dimensional Euclidean space is analysed by taking into account the non-perturbative effects of the Gribov horizon. In this way, we are able to describe the confinement and de-confinement regimes, which naturally depend on the topological mass and on the gauge coupling constant of the theory. -- Highlights: •We implement the Gribov quantization to the Topologically massive Yang–Mills theory. •We find a modified propagator at strong coupling by the Gribov horizon. •The gauge propagator depends on the topological mass and the coupling constant. •By studying the gauge propagator we describe the confined–deconfined regimes.

    We derive non-Abelian localization formulas for supersymmetric Yang-Mills-Chern-Simons theory with matters on a Seifert manifold M, which is the three-dimensional space of a circle bundle over a two-dimensional Riemann surface Σ, by using the cohomological approach introduced by Källén. We find that the partition function and the vacuum expectation value of the supersymmetric Wilson loop reduces to a finite dimensional integral and summation over classical flux configurations labeled by discrete integers. We also find that the partition function reduces further to just a discrete sum over integers in some cases, and evaluate the supersymmetric index (Witten index) exactly on S1×Σ. The index completely agrees with the previous prediction from field theory and branes. We discuss a vacuum structure of the Aharony-Bergman-Jafferis-Maldacena theory deduced from the localization.

    We gauge the abelian hierarchy of tensor fields in 4D by a Lie algebra g. The resulting non-abelian tensor hierarchy can be interpreted via a g-equivariant chain complex. We lift this structure to N=1 superspace by constructing superfield analogs for the tensor fields, along with covariant superfield strengths. Next we construct Chern-Simons actions, for both the bosonic and N=1 cases, and note that the condition of gauge invariance can be presented cohomologically. Finally, we provide an explicit realization of these structures by dimensional reduction, for example by reducing the three-form of eleven-dimensional supergravity into a superspace with manifest 4D, N=1 supersymmetry.

    We consider a nonrelativistic model where a Schrodinger field has been coupled to an abelian Chern-Simons term. By performing Hamiltonian analysis of the model using the Faddeev{endash}Jackiw symplectic method, we first demonstrate the closure of the Galilean algebra at the classical level in a gauge independent manner. By suitably taking into account the effects of operator ordering, we then show once again in a gauge independent way that this closure is also preserved for the corresponding quantum theory. The gauge fixed analysis, on the contrary, reveals that galilean invariance is valid only for the classical case. This is explicitly demonstrated both for the radiation gauge, as well as for a nonconventional gauge where the phase of the scalar field is fixed. Subtleties related to the definition of the angular momentum operator, both at the classical and quantum levels, are illuminated. {copyright} 1996 Academic Press, Inc.

    A Galilean Chern-Simons field theory is formulated for the case of two interacting spin-1/2 fields of distinct masses M and M{sup {prime}}. A method for the construction of states containing N particles of mass M and N{sup {prime}} particles of mass M{sup {prime}} is given which is subsequently used to display equivalence to the spin-1/2 Aharonov-Bohm effect in the N=N{sup {prime}}=1 sector of the model. The latter is then studied in perturbation theory to determine whether there are divergences in the fourth order (one-loop) diagram. It is found that the contribution of that order is finite (and vanishing) for the case of parallel spin projections while the antiparallel case displays divergences which are known to characterize the spin-0 case in field theory as well as in quantum mechanics. {copyright} {ital 1997} {ital The American Physical Society}

  8. Anomaly-induced effective action and Chern–Simons modification of general relativity

    Directory of Open Access Journals (Sweden)

    Sebastião Mauro

    2015-06-01

    Full Text Available Recently it was shown that the quantum vacuum effects of massless chiral fermion field in curved space–time leads to the parity-violating Pontryagin density term, which appears in the trace anomaly with imaginary coefficient. In the present work the anomaly-induced effective action with the parity-violating term is derived. The result is similar to the Chern–Simons modified general relativity, which was extensively studied in the last decade, but with the kinetic terms for the scalar different from those considered previously in the literature. The parity-breaking term makes no effect on the zero-order cosmology, but it is expected to be relevant in the black hole solutions and in the cosmological perturbations, especially gravitational waves.

    We consider the class of higher derivative 3d vector field models with the wave operator being a polynomial of the Chern-Simons operator. For the nth order theory of this type, we provide a covariant procedure for constructing n-parameter family of conservation laws associated with spatiotemporal symmetries. This family includes the canonical energy that is unbounded from below, whereas others conservation laws from the family can be bounded from below for certain combinations of the Lagrangian parameters, even though higher derivatives are present in the Lagrangian. We prove that any conserved quantity bounded from below is related with invariance of the theory with respect to the time translations and ensures the stability of the model.

    The Cambrian Mount Simon Sandstone is the major target reservoir for ongoing geologic carbon dioxide (CO2) sequestration demonstrations throughout the midwest United States. The potential CO2 reservoir capacity, reactivity, and ultimate fate of injected CO2 depend on textural and compositional properties determined by depositional and diagenetic histories that vary vertically and laterally across the formation. Effective and efficient prediction and use of the available pore space requires detailed knowledge of the depositional and diagenetic textures and mineralogy, how these variables control the petrophysical character of the reservoir, and how they vary spatially. Here, we summarize the reservoir characteristics of the Mount Simon Sandstone based on examination of geophysical logs, cores, cuttings, and analysis of more than 150 thin sections. These samples represent different parts of the formation and depth ranges of more than 9000 ft (>2743 m) across the Illinois Basin and surrounding areas. This work demonstrates that overall reservoir quality and, specifically, porosity do not exhibit a simple relationship with depth, but vary both laterally and with depth because of changes in the primary depositional facies, framework composition (i.e., feldspar concentration), and diverse diagenetic modifications. Diagenetic processes that have been significant in modifying the reservoir include formation of iron oxide grain coatings, chemical compaction, feldspar precipitation and dissolution, multiple generations of quartz overgrowth cementation, clay mineral precipitation, and iron oxide cementation. These variables provide important inputs for calculating CO2 capacity potential, modeling reactivity, and are also an important baseline for comparisons after CO2 injection. Copyright ??2011.

  11. The self in conflict: Actors and agency in the mediated sequential Simon Task

    2015-03-01

    Full Text Available Executive control refers to the ability to withstand interference in order to achieve task goals. The effect of conflict adaptation describes that after experiencing interference, subsequent conflict effects are weaker. However, changes in the source of conflict have been found to disrupt conflict adaptation. Previous studies indicated that this specificity is determined by the degree to which one source causes episodic retrieval of a previous source. A virtual reality version of the Simon task was employed to investigate whether changes in a visual representation of the self would similarly affect conflict adaptation. Participants engaged in a mediated Simon task via 3D avatar models that either mirrored the participants’ movements, or were presented statically. A retrieval cue was implemented as the identity of the avatar: switching it from a male to a female avatar was expected to disrupt the conflict adaptation effect. The results show that only in static conditions did the conflict adaptation effect depend on the avatar identity, while in dynamic conditions, changes did not cause disruption. We also explored the effect of conflict and adaptation on the degree of movement made with the task-irrelevant hand and replicated the reaction time pattern. The findings add to earlier studies of source-specific conflict adaptation by showing that a visual representation of the self in action can provide a cue that determines episodic retrieval. Furthermore, the novel paradigm is made openly available to the scientific community and is described in its significance for studies of social cognition, cognitive psychology and human-computer interaction.

    We consider D=3 supersymmetric Chern Simons gauge theories both from the point of view of their formal structure and of their applications to the AdS{sub 4}/CFT{sub 3} correspondence. From the structural view-point, we use the new formalism of integral forms in superspace that utilizes the rheonomic Lagrangians and the Picture Changing Operators, as an algorithmic tool providing the connection between different approaches to supersymmetric theories. We provide here the generalization to an arbitrary Kaehler manifold with arbitrary gauge group and arbitrary superpotential of the rheonomic lagrangian of D=3 matter coupled gauge theories constructed years ago. From the point of view of the AdS{sub 4}/CFT{sub 3} correspondence and more generally of M2-branes we emphasize the role of the Kaehler quotient data in determining the field content and the interactions of the Cherns Simons gauge theory when the transverse space to the brane is a non-compact Kaehler quotient K{sub 4} of some flat variety with respect to a suitable group. The crepant resolutions of C{sup n}/Γ singularities fall in this category. In the present paper we anticipate the general scheme how the geometrical data are to be utilized in the construction of the D=3 Chern-Simons Theory supposedly dual to the corresponding M2-brane solution.

    2016-09-01

    We calculate the Chern-Simons invariants of twist-knot orbifolds using the Schläfli formula for the generalized Chern-Simons function on the family of twist knot cone-manifold structures. Following the general instruction of Hilden, Lozano, and Montesinos-Amilibia, we here present concrete formulae and calculations. We use the Pythagorean Theorem, which was used by Ham, Mednykh and Petrov, to relate the complex length of the longitude and the complex distance between the two axes fixed by two generators. As an application, we calculate the Chern-Simons invariants of cyclic coverings of the hyperbolic twist-knot orbifolds. We also derive some interesting results. The explicit formulae of the A-polynomials of twist knots are obtained from the complex distance polynomials. Hence the edge polynomials corresponding to the edges of the Newton polygons of the A-polynomials of twist knots can be obtained. In particular, the number of boundary components of every incompressible surface corresponding to slope -4n+2 turns out to be 2. Bibliography: 39 titles.

    2016-03-01

    Functional near-infrared spectroscopy (fNIRS) is a low-cost, portable and noninvasive functional neuroimaging technique by measuring the change in the concentrations of oxyhemoglobin (HbO) and deoxyhemoglobin (HbR). The aim of present study is to reveal the different brain activity pattern of adult subjects during the completion of flanker and Simon tasks underlying the congruent and incongruent test conditions so as to identify the basic neural mechanism of inhibitory control in executive function. In the study, we utilized fNIRS to explore the hemodynamic changes in the prefrontal cortex and our imaging results suggested that there were notable differences for the hemodynamic responses between the flank and Simon task. A striking difference is that for the flank task, the increase in the HbO concentration during incongruent trials was larger than that during congruent trials for the channels across middle frontal cortex while for the Simon task, the hemodynamic response was stronger for the congruent condition compared to that from the incongruent one. Interestingly, the hemodynamic response exhibited similar task-related activation in the superior frontal cortex for both the congruent and incongruent conditions. Further, independent component analysis showed that different brain activation patterns were identified to accomplish different inhibitory control tasks underlying the congruent and incongruent conditions.

We perform a two-loop evaluation and find the same result for the two kinds of operators, so moving to higher loops a possible quantum uplift of the classical degeneracy. We also compute the 1/4 BPS bosonic Wilson loop and discuss the quantum version of the cohomological equivalence between fermionic and bosonic Wilson loops. We compare the perturbative result with the Matrix Model prediction and find perfect matching, after identification and remotion of a suitable framing factor. Finally, we discuss the potential appearance of three-loop contributions that might break the classical degeneracy and briefly analyze possible implications on the BPS nature of these operators.

  19. Mindblindness: metaphor and neuroaesthetics in the works of Silas Weir Mitchell and Simon Baron-Cohen.

    Science.gov (United States)

    Swenson, Kristine

    2013-01-01

    Silas Weir Mitchell's novel, When All the Woods are Green (1894), acknowledges the medical use of mindblindness (agnosia) but also casts it as a developmental disorder, bringing it provocatively close to how current neuropsychologist, Simon Baron-Cohen and his followers use the term in relation to autism. This chapter traces the mindblindess metaphor in the works of Mitchell and Baron-Cohen to show how mindblindness informs the larger paradigms by which they theorize the brain. This analysis suggests that Baron-Cohen, and thus much current thinking about autism spectrum conditions, is influenced by Victorian-era cultural assumptions and neurosexism, a connection that calls for scrutiny of Baron-Cohen's current models of the brain and theories of autism. This chapter also demonstrates the extent to which Mitchell used fiction and advocated writing as neuroaesthetic tools and thus bridged in his work cognitive science and aesthetics--a connection that current scholars of neuroaesthetics are now theorizing. © 2013 Elsevier B.V.

  20. Doubled Lattice Chern-Simons-Yang-Mills Theories with Discrete Gauge Group

    CERN Document Server

    Caspar, Stephan; Olesen, Therkel Z; Vlasii, Nadiia D; Wiese, Uwe-Jens

    2016-01-01

    We construct doubled lattice Chern-Simons-Yang-Mills theories with discrete gauge group $G$ in the Hamiltonian formulation. Here, these theories are considered on a square spatial lattice and the fundamental degrees of freedom are defined on pairs of links from the direct lattice and its dual, respectively. This provides a natural lattice construction for topologically-massive gauge theories, which are invariant under parity and time-reversal symmetry. After defining the building blocks of the doubled theories, paying special attention to the realization of gauge transformations on quantum states, we examine the dynamics in the group space of a single cross, which is spanned by a single link and its dual. The dynamics is governed by the single-cross electric Hamiltonian and admits a simple quantum mechanical analogy to the problem of a charged particle moving on a discrete space affected by an abstract electromagnetic potential. Such a particle might accumulate a phase shift equivalent to an Aharonov-Bohm pha...

  1. Testing Chern-Simons modified gravity with observations of extreme-mass-ratio binaries

    2012-01-01

    Extreme-Mass-Ratio Inspirals (EMRIs) are one of the most promising sources of gravitational waves (GWs) for space-based detectors like the Laser Interferometer Space Antenna (LISA). EMRIs consist of a compact stellar object orbiting around a massive black hole (MBH). Since EMRI signals are expected to be long lasting (containing of the order of hundred thousand cycles), they will encode the structure of the MBH gravitational potential in a precise way such that features depending on the theory of gravity governing the system may be distinguished. That is, EMRI signals may be used to test gravity and the geometry of black holes. However, the development of a practical methodology for computing the generation and propagation of GWs from EMRIs in theories of gravity different than General Relativity (GR) has only recently begun. In this paper, we present a parameter estimation study of EMRIs in a particular modification of GR, which is described by a four-dimensional Chern-Simons (CS) gravitational term. We focu...

    In this study, we investigated whether the processing of written words leads to a preferential coding of word beginnings and whether this coding occurs in the context of word representations that are spatial in nature and depend on the orientation of the actual stimuli. Two experiments were carried out wherein participants were asked to press a left or right key, in accordance with a nonspatial feature of standard-oriented or mirror-reversed wordlike stimuli (words and pronounceable nonwords). Both experiments showed an effect of correspondence between position of the beginning part of the stimuli and position of the required response (i.e., a Simon-like effect): Responses to standard-oriented stimuli were faster with the left key, whereas responses to mirror-reversed stimuli were faster with the right key. The present findings indicate for the first time that, in reading, the direction of script is automatically processed and the position of the word beginning is coded before the orthographic lexicon is accessed.

  3. Narcissism, Abjection and the Reader(e of Simone de Beauvoir's Les Belles Images

    2008-01-01

    Full Text Available Discussions of Simone de Beauvoir's last novel, Les Belles Images (1966, tend to be in the mode of apology. The characters are shallow—runs the typical claim—the plot (essentially, Laurence's gradual awakening to her own "belle image" identity of feminine clichés as fulfilled wife, devoted mother, successful professional flimsy and predictable. Yet, in studying a specular dynamic of narcissism and abjection within the novel, we become aware of the discomforting ways in which our own scorn for Laurence and her world is anticipated by the text. As we attend upon the dismantling of Laurence's "belles images," we are made to witness the undoing of our own narcissism. Along the way, we acquire new understanding of an important aspect of this specular relationship: the novel's slippery use of the pronouns "I" and "she" to refer to Laurence, in an unstable grammar that has confounded critics. These pronouns and their imbrication are only too pertinent, I argue, for the reader's relationship to Laurence, and for the ways in which the reader's "I" sets itself loftily apart from Laurence's "she." Yet, in dismantling the reader's assumptions along with those of Laurence, the text offers each a new way forward, beyond the crippling confines of narcissism and abjection.

    The spectroscopic observations considered for this study are part of the IACOB spectroscopic database of northern Galactic OB stars (last described in Simon-Diaz et al., 2011, Bull. Soc. Roy. Sci. Liege, 80, 514 and Stellar Clusters and Associations: Proc. A RIA Workshop on Gaia, eds. E. J. Alfaro Navarro, A. T. Gallego Calvente, & M. R. Zapatero Osorio, 255). This unique high-quality spectroscopic database has been compiled in the framework of the IACOB project. To date, the IACOB database comprises 1250 spectra of 153 and 97 Galactic O- and early B-type stars, respectively, observable from the Roque de los Muchachos observatory in La Palma (Spain). The spectra have a resolving power of 46000 and 23000, a typical signal-to-noise ratio (S/N) above 150, and were compiled between November 2008 and January 2013 with the high-resolution FIbre-fed Echelle Spectrograph (FIES) attached to the Nordic Optical Telescope (NOT). The IACOB database has a multi-epoch character that enables investigations of the binary/multiple nature of considered stars and the temporal variations in individual objects with at least three spectra per observed target. In this study, we only used a subsample of the spectra, discarding all stars with signatures of multiplicity (which means that we only considered apparently single and SB1 stars), and only considering the spectrum with the highest S/N ratio per star.

    Full Text Available The purpose of this paper is to study the cosmological evolution of the universe in the framework of dynamical Chern-Simons modified gravity. We take pilgrim dark energy model with Hubble and event horizons in interacting scenario with cold dark matter. For this scenario, we discuss cosmological parameters such as Hubble and equation of state and cosmological plane like ωϑ-ωϑ′ and squared speed of sound. It is found that Hubble parameter approaches the ranges 75-0.5+0.5 (for u=2 and (74, 74.30 (for u=1,-1,-2 for Hubble horizon pilgrim dark energy. It implies the ranges 74.80-0.005+0.005 (for u=2 and (73.4, 74 (for u=-2 for event horizon pilgrim dark energy. The equation of state parameter provides consistent ranges with different observational schemes. Also, ωϑ-ωϑ′ planes lie in the range (ωϑ=-1.13-0.25+0.24,ωϑ′<1.32. The squared speed of sound shows stability for all present models in the present scenario. We would like to mention here that our results of various cosmological parameters show consistency with different observational data like Planck, WP, BAO, H0, SNLS, and WMAP.

  6. How to read Simon Forman's casebooks: medicine, astrology, and gender in Elizabethan London.

    Simon Forman's astrological casebooks record thousands of medical consultations. Amidst the wealth of information in these documents, however, it is unclear to what extent Forman relied on the stars for diagnoses and therapies, or how the casebooks reflect the dymanic between Forman and his clients. This article attempts to answer these questions by reading the casebooks alongside Forman's guide to astrological physic. This approach reveals that astrology was paramount in Forman's evaluations and treatments of his patients. According to Forman, in order for him to effect a cure, he had to be trusted. It was particularly difficult to treat women because their health depended on the state of their wombs, and on their sexual activity, subjects about which women were notoriously duplicitous. The task of the astrologer was first to assess whether or not a woman was sexually active, and only then could he make a judgement about her disease. At the same time, in demonstrating an ability to discern whether or not she was being honest about her sexual activities, Forman won her confidence. By accounting for the role of astrology and the dynamics between the patient and the physician, this article provides the framework within which to read one of the most comprehensive records of medical practices in early modern England.

    Full Text Available Simon Vestdijk is one of the most prominent figures in the literary awareness of the Netherlands. From an intertextual study between De toekomst der religie (The Future of Religion and De koperen tuin (The Copper Garden it emerges that the postulated view of reality is transposed in narrative form in the text-internal vision of reality in the novel. This transformation is concretized and manifested in visible terms in the character portrayal, especially with regard to music as the passion to which the main character dedicates himself. The many references to music in the novel gradually gain importance as a motif that becomes a symbol of different kinds of love. In the course of the narrative, and especially towards the end of it, there is a substitution of religious value contents in the main character who is led to humanistic love through music, so that this process of transvaluation of religion (in the wider sense of the word becomes the main emphasis of the discourse of the novel, albeit in veiled form.

  8. Coupled Reactive Transport Modeling of CO2 Injection in Mt. Simon Sandstone Formation, Midwest USA

    CO2 sequestration in deep geological formations is one of the promising options for CO2 emission reduction. While several large scale CO2 injections in saline aquifers have shown to be successful for the short-term, there is still a lack of fundamental understanding on key issues such as CO2 storage capacity, injectivity, and security over multiple spatial and temporal scales that need to be addressed. To advance these understandings, we applied multi-phase coupled reactive mass transport modeling to investigate the fate of injected CO2 and reservoir responses to the injection into Mt. Simon Formation. We developed both 1-D and 2-D reactive transport models in a radial region of 10,000 m surrounding a CO2 injection well to represent the Mt. Simon sandstone formation, which is a major regional deep saline reservoir in the Midwest, USA. Supercritical CO2 is injected into the formation for 100 years, and the modeling continues till 10,000 years to monitor both short-term and long-term behavior of injected CO2 and the associated rock-fluid interactions. CO2 co-injection with H2S and SO2 is also simulated to represent the flue gases from coal gasification and combustion in the Illinois Basin. The injection of CO2 results in acidified zones (pH ~3 and 5) adjacent to the wellbore, causing progressive water-rock interactions in the surrounding region. In accordance with the extensive dissolution of authigenic K-feldspar, sequential precipitations of secondary carbonates and clay minerals are predicted in this zone. The vertical profiles of CO2 show fingering pattern from the top of the reservoir to the bottom due to the density variation of CO2-impregnated brine, which facilitate convection induced mixing and solubility trapping. Most of the injected CO2 remains within a radial distance of 2500 m at the end of 10,000 years and is sequestered and immobilized by solubility and residual trapping.

  9. Detecting telomere elongation in longitudinal datasets: analysis of a proposal by Simons, Stulp and Nakagawa

    2017-04-01

    Full Text Available Telomere shortening has emerged as an important biomarker of aging. Longitudinal studies consistently find that, although telomere length shortens over time on average, there is a subset of individuals for whom telomere length is observed to increase. This apparent lengthening could either be a genuine biological phenomenon, or simply due to measurement and sampling error. Simons, Stulp & Nakagawa (2014 recently proposed a statistical test for detecting when the amount of apparent lengthening in a dataset exceeds that which should be expected due to error, and thus indicating that genuine elongation may be operative in some individuals. However, the test is based on a restrictive assumption, namely that each individual’s true rate of telomere change is constant over time. It is not currently known whether this assumption is true. Here we show, using simulated datasets, that with perfect measurement and large sample size, the test has high power to detect true lengthening as long as the true rate of change is either constant, or moderately stable, over time. If the true rate of change varies randomly from year to year, the test systematically returns type-II errors (false negatives; that is, failures to detect lengthening even when a substantial fraction of the population truly lengthens each year. We also consider the impact of measurement error. Using estimates of the magnitude of annual attrition and of measurement error derived from the human telomere literature, we show that power of the test is likely to be low in several empirically-realistic scenarios, even in large samples. Thus, whilst a significant result of the proposed test is likely to indicate that true lengthening is present in a data set, type-II errors are a likely outcome, either if measurement error is substantial, and/or the true rate of telomere change varies substantially over time within individuals.

    Full Text Available Este trabajo nace con la intención de recuperar y actualizar un artículo clásico de la psicología del deporte como es el de Simon y Martens del 1979. Como su antecesor, nuestro trabajo compara la ansiedad rasgo competitiva en deportes y actividades lúdicas que se clasifican en base a dos variables de agrupación: la Colaboración, que diferencia entre actividades individuales y colectivas, y la Habilidad, que separa aquellas actividades que requieren de habilidades habituales de las que requieren de habilidades perceptivas. 643 deportistas y 140 castellers contestaron la Escala de Ansiedad Competitiva-2 y sus puntuaciones fueron comparadas mediante análisis de la varianza en función de las variables Colaboración, Habilidad y la interacción entre ambas. Los resultados indican que en aquellas actividades cuya habilidad es de tipo habitual, aparecen niveles más altos en el factor de Ansiedad Somática y Preocupación. Además, los participantes en deportes individuales relatan mayores niveles de Desconcentración que aquellos que realizan deportes o actividades colectivas. Se detecta también un efecto interactivo de las variables colaboración y habilidad sobre la Preocupación. Se ha realizado una comparación adicional deportistas y castellers, como actividad evaluativa no deportiva, revelando que el nivel de Ansiedad Somática de los castellers es equivalente al de los deportistas, pero que en las variables de Preocupación y Desconcentración los deportistas relatan niveles significativamente mayores. Finalmente se discute la importancia de conocer las características de cada modalidad deportiva de cara al trabajo específico con los entrenadores y padres para el trabajo preventivo de la ansiedad.

  12. Alcohol approach tendencies in heavy drinkers: comparison of effects in a Relevant Stimulus-Response Compatibility task and an approach/avoidance Simon task.

    2011-12-01

    Several recent studies suggest that alcohol-related cues elicit automatic approach tendencies in heavy drinkers. A variety of tasks have been used to demonstrate these effects, including Relevant Stimulus-Response Compatibility (R-SRC) tasks and variants of Simon tasks. Previous work with normative stimuli suggests that the R-SRC task may be more sensitive than Simon tasks because the activation of approach tendencies may depend on encoding of the stimuli as alcohol-related, which occurs in the R-SRC task but not in Simon tasks. Our aim was to directly compare these tasks for the first time in the context of alcohol use. We administered alcohol versions of an R-SRC task and a Simon task to 62 social drinkers, who were designated as heavy or light drinkers based on a median split of their weekly alcohol consumption. Results indicated that, compared to light drinkers, heavy drinkers were faster to approach, rather than avoid, alcohol-related pictures in the R-SRC task but not in the Simon task. Theoretical implications and methodological issues are discussed.

    Having great accuracy in the range and range rate measurements, the GRACE mission and the planed GRACE follow on mission can in principle be employed to place strong constraints on certain relativistic gravitational theories. In this paper, we work out the range observable of the non-dynamical Chern-Simons modified gravity for the satellite-to-satellite tracking (SST) measurements. We find out that a characteristic time accumulating range signal appears in non-dynamical Chern-Simons gravity, which has no analogue found in the standard parity-preserving metric theories of gravity. The magnitude of this Chern-Simons range signal will reach a few times of χ cm for each free flight of these SST missions, here χ is the dimensionless post-Newtonian parameter of the non-dynamical Chern-Simons theory. Therefore, with the 12 years data of the GRACE mission, one expects that the mass scale M{sub CS} = (4ℎc)/(χa) of the non-dynamical Chern-Simons gravity could be constrained to be larger than 1.9 x 10.9 eV. For the GRACE FO mission that scheduled to be launched in 2017, the much stronger bound that M{sub CS} ≥ 5 x 10{sup -7} eV is expected. (orig.)

    I explore the existence of a massive phase in a conformally invariant U(N) Chern-Simons gauge theories in D = 3 with matter fields in the fundamental representation. These models have attracted recent attention as being dual, in the conformal phase, to theories of higher spin gravity on AdS 4. Using the 0t Hooft large N expansion, exact solutions are obtained for scalar current correlators in the massive phase where the conformal symmetry is spontaneously broken. A massless dilaton appears as a composite state, and its properties are discussed. Solutions exist for matters field that are either bosons or fermions.

Ellos proceden del enfrentamiento intelectual con nuestro tiempo, se originan por los actuales discursos sociales, reflexionan sobre la actualidad. Las obras del artista que vive en Dresde desconciertan al espectador en cuanto a la forma y al contenido. Muy a menudo no son conformes a las espectativas. Las ambivalencias y las ambigüedades están intencionadas. Conscientemente sus obras niegan a una localización espacial y temporal. Imagínan una cierta atemporalidad y son imágenes con un subtexto político. Referiéndose a la historia cultural el artista crea a su propio mundo pictórico en cual los temas europeos y la pregunta por el poder juegan un papel importante. Las obras presentadas muestran a Rosenthal como «homo politicus». The narrative paintings of the young German artist Simon Rosenthal, who lives in Dresden, mark an extraordinary and strong position in the field of contemporary figurative painting. Arising from the intellectual examination of our time, they ignite at contemporary discourses, always reflecting the now. Containing multiple irritations in form and content, they deliberately break with the viewer’s expectations in many ways, evoking all kinds of ambiguities and ambivalence. Negating any regional or temporal classification, Rosenthal’s works conjure up a sphere above time, and may be looked at as a profound sort of political riddles. Referring to cultural history, he creates a unique figurative cosmos, where European themes are raised, closely linked with the question of power. The presented works show the artist Simon Rosenthal as «homo politicus».

    Full Text Available In mediaeval Serbian law the central legal term zakon (law indicated a generally obligatory rule (regula iuris which was usually not a result of the activity of a monarch as ultimate holder of state power. Even where a law was made by state authority such a legal rule had primarily the appearence of a customary legal provision, regulating the conditions within one particular manor (vlastelinstvo rather than within the whole national territory. Otherwise such laws prescibed the legal position of different categories of inhabitants and identified particular rules of status. Sometimes a law would be introduced to regulate one paricular problem. The concept of law in this period also includes a legal rule derived from custom or from a private contract. Each of these uses can be illustrated from many hundreds of cases from several sources. The use of the term zakon (law was present in the literary sources as well, such is The Life of Saint Simon (biography of Stefan Nemanja, founder of Serbian mediaeval dynasty Nemanjić, written by his youngest son Rastko, bether known under his monastic name Sabba (Sava. In Sabba's hagiography of his father we found the term zakon six times. Discribing the State Council (Državni sabor that had to decide who will be Nemanja's successor on the throne, Sabba writes that his father pronounced, among other, the following words: 'My sons, do not forget the orthodox law that I established.' The term orthodox law means here orthodox faith, that was established in Serbia after persecutions of Bogomilian heresy. For the second time, term zakon was used in the meaning of monarch's order. Nemanja says to his sons not to forget his laws. Further, giving the instructions to his sons, Nemanja use the citation from the Bible (The Book of Proverbs or Proverbs of Solomon 3, 1-18, where the term zakon corresponds to the latin ius, not lex.

    2016-01-01

    Full Text Available We have studied the existence of self-dual solitonic solutions in a generalization of the Abelian Chern-Simons-Higgs model. Such a generalization introduces two different nonnegative functions, ω1(|ϕ| and ω(|ϕ|, which split the kinetic term of the Higgs field, |Dμϕ|2→ω1(|ϕ||D0ϕ|2-ω(|ϕ||Dkϕ|2, breaking explicitly the Lorentz covariance. We have shown that a clean implementation of the Bogomolnyi procedure only can be implemented whether ω(|ϕ|∝β|ϕ|2β-2 with β≥1. The self-dual or Bogomolnyi equations produce an infinity number of soliton solutions by choosing conveniently the generalizing function ω1(|ϕ| which must be able to provide a finite magnetic field. Also, we have shown that by properly choosing the generalizing functions it is possible to reproduce the Bogomolnyi equations of the Abelian Maxwell-Higgs and Chern-Simons-Higgs models. Finally, some new self-dual |ϕ|6-vortex solutions have been analyzed from both theoretical and numerical point of view.

    Full Text Available The research objective is to analyse why the accounts of two missionaries who visited the same Mongol “Other” in 1245 are quite different, despite their authors belonging to the same Christian circle. More specifically, the paper explores why Simon’s report is so much more negative in its depiction of the Mongols, and the imagological and emotional impact that these representations had. My research materials include the two mendicant reports produced by John and Simon as well as extant scholarly discussions of various aspects of the Mongol Other, apocalyptic literature, and the relations between Western Christendom and the Mongol Empire in the mid-13th century. The research innovation of the article is in the comparison of the two contemporary accounts, the elaboration of their differences in representation of the Mongols, and the analysis of their imagery from the perspective of the history of emotions. The aim of this paper is to show that in interpreting medieval European texts about the Mongols, one should combine approaches from various fields, including (but not limited to history of emotions, cultural and literal history, anthropology, cross-cultural sociology, and others. Immediate and incorrect interpretations that the Mongols were cannibals or sodomites, as one could be tempted to hold from the account of Simon of Saint-Quentin, must be moderated from scholarly perspectives. These interpretations were the result of sediment layers of events in the 1240s: the violent contact of the Mongol armies with Western Christendom, contemporary Christian attempts to put the newcomers into known apocalyptic frameworks, and most probably the personal trauma of the author who had been threatened with death after an inaction with the Mongols, might be explained both as a cross-cultural misunderstanding and a display of power.

    Full Text Available The Simon Effect is a phenomenon in which reaction times are usually faster when the stimulus location and the response correspond, even if the stimulus location is irrelevant to the task. Recent studies have demonstrated the Simon effect in a three-dimensional (3-D display. The present study examined whether two-dimensional (2-D and 3-D locations simultaneously affected the Simon effect for the stimuli in which a target stimulus and fixation were located on the same plane (ground or ceiling at different 3-D depths, and the perspective effect produced difference in the 2-D vertical location of the target stimulus relative to the fixation. The presence of a ground and ceiling plane was controlled to examine the contextual effect of background. The results showed that the 2-D vertical location and 3-D depth simultaneously affected the speed of responses, and they showed no interaction. The presence of the background did not affect the magnitude of either the 2-D or the 3-D Simon effect. These results suggest that 2-D vertical location and 3-D depth are coded simultaneously and independently, and both of them affect the response selection in which 2-D and 3-D representations overlap.

  7. Fast and unintentional evaluation of emotional sounds: evidence from brief segment ratings and the affective Simon task.

    Science.gov (United States)

    Folyi, Tímea; Wentura, Dirk

    2017-02-01

    In the present study, we raised the question of whether valence information of natural emotional sounds can be extracted rapidly and unintentionally. In a first experiment, we collected explicit valence ratings of brief natural sound segments. Results showed that sound segments of 400 and 600 ms duration-and with some limitation even sound segments as short as 200 ms-are evaluated reliably. In a second experiment, we introduced an auditory version of the affective Simon task to assess automatic (i.e. unintentional and fast) evaluations of sound valence. The pattern of results indicates that affective information of natural emotional sounds can be extracted rapidly (i.e. after a few hundred ms long exposure) and in an unintentional fashion.

    Full Text Available In the first order formalism of gravity theories, there are some theories which are not Lorentz-diffeomorphism covariant. In the framework of such theories we cannot apply the method of conserved charge calculation used in Lorentz-diffeomorphism covariant theories.

Secondly, in order to obtain the conserved charges of Lorentz-diffeomorphism non-covariant theories, we extend the Tachikawa method [1]. This extension includes not only Lorentz gauge transformation but also the diffeomorphism. We apply this method to the Chern–Simons-like theories of gravity (CSLTG and obtain a general formula for the entropy of black holes in those theories. Finally, some examples on CSLTG are provided and the entropy of the BTZ black hole is calculated in the context of the examples.

This article will focus on a triadic concept in her autobiographical oeuvre and on the effects her texts have on cultural interpolation. Deeply critical of the discursive parameters of tradition, which are devoted to logical and ontological principles, Beauvoir proposes new ways of thinking. From a methodological perspective, this article will address this theme in various levels of reading, namely: the conceptual, historical and hermeneutical. It will focus on the feminine as the principal character in its philosophical-literary texts, in terms of its subjectivity and alterity, while being a provocative fact in the search of a redefinition for the meaning of aesthetic symmetry.

  12. Case study - Dynamic pressure-limited capacity and costs of CO2 storage in the Mount Simon sandstone

    2017-01-01

    Widespread deployment of carbon capture and storage (CCS) is likely necessary to be able to satisfy baseload electricity demand, to maintain diversity in the energy mix, and to achieve climate and other objectives at the lowest cost. If all of the carbon dioxide (CO2) emissions from stationary sources (such as fossil-fuel burning power plants, and other industrial plants) in the United States needed to be captured and stored, it could be possible to store only a small fraction of this CO2 in oil and natural gas reservoirs, including as a result of CO2 utilization for enhanced oil recovery. The vast majority would have to be stored in saline-filled reservoirs (Dahowski et al., 2005). Given a lack of long-term commercial-scale CCS projects, there is considerable uncertainty in the risks, dynamic capacity, and their cost implications for geologic storage of CO2. Pressure buildup in the storage reservoir is expected to be a primary source of risk associated with CO2 storage, and could severely limit CO2 injection rates (dynamic storage capacities). Most cost estimates for commercial-scale deployment of CCS estimate CO2 storage costs under assumed availability of a theoretical capacity to store tens, hundreds, or even thousands of gigatons of CO2, without considering geologic heterogeneities, pressure limitations, or the time dimension. This could lead to underestimation of the costs of CO2 storage (Anderson, 2017). This paper considers the impacts of pressure limitations and geologic heterogeneity on the dynamic CO2 storage capacity and storage (injection) costs. In the U.S. Geological Survey (USGS)’s National Assessment of Geologic CO2 Storage Resources (USGS, 2013), the mean estimate of the theoretical storage capacity in the Mount Simon Sandstone was about 94 billion metric tons of CO2. However, our results suggest that the pressure-limited capacity after 50 years of injection could be only about 4% of the theoretical geologic storage capacity in this formation

  15. Edge theory approach to topological entanglement entropy and other entanglement measures of (2+1) dimensional Chern-Simons theories on a general manifold

    Science.gov (United States)

    Wen, Xueda; Matsuura, Shunji; Ryu, Shinsei

    Topological entanglement entropy of (2+1) dimensional Chern-Simons gauge theories on a general manifold is usually calculated with Witten's method of surgeries and replica trick, in which the spacetime manifold under consideration is very complicated. In this work, we develop an edge theory approach, which greatly simplifies the calculation of topological entanglement entropy of a Chern-Simons theory. Our approach applies to a general manifold with arbitrary genus. The effect of braiding and fusion of Wilson lines can be straightforwardly calculated within our framework. In addition, our method can be generalized to the study of other entanglement measures such as mutual information and entanglement negativity of a topological quantum field theory on a general manifold.

  16. Chern-Simons Theories with Fundamental Matter: A Brief Review of Large N Results Including Fermi-Bose Duality and the S-matrix

    Science.gov (United States)

    Wadia, Spenta R.

    We begin with a few words about Salam's contribution to the growth of String Theory in India. In the technical talk we review results in SU(N) Chern-Simons plus vector matter theories in 2+1 dim in the large N limit. The dressing of charged matter by Chern-Simons gauge fields leads to anyons that interpolate between fermions and bosons and lead to a duality symmetry between fermionic and bosonic theories. The S-matrix (defined in the large N limit) besides exhibiting this duality, also exhibits novel properties due to the presence of anyons. The S-matrix is not analytic, like in Aharonov-Bohm scattering, and satisfies modified crossing symmetry relations.

    Full text: Since the seminal works by Abrikosov [1] and Nielsen-Olesen [2] showing the existence of uncharged vortex, such nonperturbative solutions have been a theoretical issue of enduring interest. Already, the electrically charged vortices are obtained only in abelian models endowed with the Chern-Simons term [3,4]. This remains valid even in the context of highly nonlinear models, such as the Born-Infield electrodynamics. In this work, we demonstrated the existence of electrically charged BPS vortices in a Maxwell-Higgs model without the Chern- Simons term but endowed with a CPT-even and parity-odd Lorentz-violating (LV) structure. The LV term belonging to the CPT-even electrodynamics of the Standard Model Extension [5] plays a similar role that of the Chern-Simons term, mixing the electric and magnetic sectors. Besides the LV coefficients provide a very rich set of vortex configurations exhibiting electric's field inversion also are responsible by controlling the characteristic length of the vortex and by the flipping of the magnetic flux.

  1. Meditation-induced cognitive-control states regulate response-conflict adaptation: Evidence from trial-to-trial adjustments in the Simon task.

    Here we consider the possibility that meditation has an immediate impact on information processing. Moreover, we were interested to see whether this impact affects attentional input control, as previous observations suggest, or the handling of response conflict. Healthy adults underwent a brief single session of either focused attention meditation (FAM), which is assumed to increase top-down control, or open monitoring meditation (OMM), which is assumed to weaken top-down control, before performing a Simon task-which assesses conflict-resolution efficiency. While the size of the Simon effect (reflecting the efficiency of handling response conflict) was unaffected by type of meditation, the amount of dynamic behavioral adjustments (i.e., trial-to-trial variability of the Simon effect: the Gratton effect) was considerably smaller after OMM than after FAM. Our findings suggest that engaging in meditation instantly creates a cognitive-control state that has a specific impact on conflict-driven control adaptations. Copyright © 2015 Elsevier Inc.

  3. Particle-Hole Symmetry in the Fermion-Chern-Simons and Dirac Descriptions of a Half-Filled Landau Level

    It is well known that there is a particle-hole symmetry for spin-polarized electrons with two-body interactions in a partially filled Landau level, which becomes exact in the limit where the cyclotron energy is large compared to the interaction strength; thus, one can ignore mixing between Landau levels. This symmetry is explicit in the description of a half-filled Landau level recently introduced by Son, using Dirac fermions, but it was thought to be absent in the older fermion-Chern-Simons approach, developed by Halperin, Lee, and Read (HLR) and subsequent authors. We show here, however, that when properly evaluated, the HLR theory gives results for long-wavelength low-energy physical properties—including the Hall conductance in the presence of impurities and the positions of minima in the magnetoroton spectra for fractional quantized Hall states close to half-filling—that are identical to predictions of the Dirac formulation. In fact, the HLR theory predicts an emergent particle-hole symmetry near half-filling, even when the cyclotron energy is finite.

  5. Parallel averaging of size is possible but range-limited: a reply to Marchant, Simons, and De Fockert.

    In their recent paper, Marchant, Simons, and De Fockert (2013) claimed that the ability to average between multiple items of different sizes is limited by small samples of arbitrarily attended members of a set. This claim is based on a finding that observers are good at representing the average when an ensemble includes only two sizes distributed among all items (regular sets), but their performance gets worse when the number of sizes increases with the number of items (irregular sets). We argue that an important factor not considered by Marchant et al. (2013) is the range of size variation that was much bigger in their irregular sets. We manipulated this factor across our experiments and found almost the same efficiency of averaging for both regular and irregular sets when the range was stabilized. Moreover, highly regular sets consisting only of small and large items (two-peaks distributions) were averaged with greater error than sets with small, large, and intermediate items, suggesting a segmentation threshold determining whether all variable items are perceived as a single ensemble or distinct subsets. Our results demonstrate that averaging can actually be parallel but the visual system has some difficulties with it when some items differ too much from others. Copyright © 2013 Elsevier B.V.

    2009-11-01

    Conflict and context slow-down have been proposed as indicators of a conflict-monitoring system that initiates cognitive control to resolve conflicts in information processing. We investigated individual differences in conflict-monitoring and their associations with working memory (WM) and impulsivity. A total of 150 adults completed a Simon and an Eriksen flanker task, together with measures of WM and impulsivity. On both tasks, responses were slower and less accurate on incompatible than on compatible trials (conflict effect), and the conflict effect was larger when the preceding trial was compatible than when it was incompatible (context effect). Stimulus repetition did not explain the context effect. Individual differences could be attributed to three separable factors for each task: general speeded performance, conflict effect, and context effect. Evidence for across-task generality of these factors was sparse. Associations of these factors with impulsivity were weak at best. WM was correlated with general speed, and also with some but not all factors reflecting conflict-related processes.

    In this paper we study the near horizon symmetry algebra of the non-extremal black hole solutions of the Chern–Simons-like theories of gravity, which are stationary but are not necessarily spherically symmetric. We define the extended off-shell ADT current which is an extension of the generalized ADT current. We use the extended off-shell ADT current to define quasi-local conserved charges such that they are conserved for Killing vectors and asymptotically Killing vectors which depend on dynamical fields of the considered theory. We apply this formalism to the Generalized Minimal Massive Gravity (GMMG) and obtain conserved charges of a spacetime which describes near horizon geometry of non-extremal black holes. Eventually, we find the algebra of conserved charges in Fourier modes. It is interesting that, similar to the Einstein gravity in the presence of negative cosmological constant, for the GMMG model also we obtain the Heisenberg algebra as the near horizon symmetry algebra of the black flower solutions. Also the vacuum state and all descendants of the vacuum have the same energy. Thus these zero energy excitations on the horizon appear as soft hairs on the black hole.

  11. Evil and elder abuse: intersections of Paul Ricoeur's and Simone Weil's perspectives on evil with one abused older woman's narrative.

    Erlingsson, Christen L

    2011-10-01

    Doing violence and evil always indirectly or directly leads to making someone else suffer. Such is the dialogical structure of evil and it seems to be the dialogical structure of elder abuse as well. There is a perturbing sameness between definitions of evil and definitions of elder abuse. It is hard at times to see how or if there is any line of demarcation between the subjects. Two modern-day philosophers, Paul Ricoeur and Simone Weil have delved particularly into the concept of evil. The symbolism Ricoeur analyses in depth is that of defilement, sin, and guilt and the concept of the servile will. Integral in Weil's description of evil are the concepts of suffering and the special situation of extreme suffering, termed affliction. Grounded in the writings of Ricoeur and Weil, this paper is a series of reflections on the intersection of evil and elder abuse as exemplified in the narrative of an abused older woman. This woman provided around the clock care at home for her husband who had vascular dementia. She was also abused by her husband. This was witnessed by both family and others but no one intervened. In her narrative there were indications of defilement, sin, guilt, and true affliction as a servile will. This paper illuminates the evil of elder abuse that is harm and suffering, and the challenge of untangling issues of blame, free will, responsibility, and self-determinism. When engaging with abused, older persons it can be worthwhile for nurses to enter the encounter with non-judgemental compassion founded on the human to human connection and recognition of our mutual fallibility and potential for evil that is part of our human fragility. © 2011 Blackwell Publishing Ltd.

  12. Lorentz-diffeomorphism quasi-local conserved charges and Virasoro algebra in Chern–Simons-like theories of gravity

    Full Text Available The Chern–Simons-like theories of gravity (CSLTG are formulated at first order formalism. In this formalism, the derivation of the entropy of a black hole on bifurcation surface, as a quasi-local conserved charge is problematic. In this paper we overcome these problems by considering the concept of total variation and the Lorentz–Lie derivative. We firstly find an expression for the ADT conserved current in the context of the CSLTG which is based on the concept of the Killing vector fields. Then, we generalize it to be conserved for all diffeomorphism generators. Thus, we can extract an off-shell conserved charge for any vector field which generates a diffeomorphism. The formalism presented here is based on the concept of quasi-local conserved charges which are off-shell. The charges can be calculated on any codimension two space-like surface surrounding a black hole and the results are independent of the chosen surface. By using the off-shell quasi-local conserved charge, we investigate the Virasoro algebra and find a formula to calculate the central extension term. We apply the formalism to the BTZ black hole solution in the context of the Einstein gravity and the Generalized massive gravity, then we find the eigenvalues of their Virasoro generators as well as the corresponding central charges. Eventually, we calculate the entropy of the BTZ black hole by the Cardy formula and we show that the result exactly matches the one obtained by the concept of the off-shell conserved charges.

    In order to assess potential associations between autism spectrum disorder (ASD) phenotype, functional GI disorders and fecal microbiota, we recruited simplex families, which had only a single ASD proband and neurotypical (NT) siblings, through the Simons Simplex Community at the Interactive Autism Network (SSC@IAN). Fecal samples and metadata related to functional GI disorders and diet were collected from ASD probands and NT siblings of ASD probands (age 7-14). Functional gastrointestinal disorders (FGID) were assessed using the parent-completed ROME III questionnaire for pediatric FGIDs, and problem behaviors were assessed using the Child Behavior Check List (CBCL). Targeted quantitative polymerase chain reaction (qPCR) assays were conducted on selected taxa implicated in ASD, including Sutterella spp., Bacteroidetes spp. and Prevotella spp. Illumina sequencing of the V1V2 and the V1V3 regions of the bacterial 16S rRNA genes from fecal DNA was performed to an average depth of 208,000 and 107,000 high-quality reads respectively. Twenty-five of 59 ASD children and 13 of 44 NT siblings met ROME III criteria for at least one FGID. Functional constipation was more prevalent in ASD (17 of 59) compared to NT siblings (6 of 44, P = 0.035). The mean CBCL scores in NT siblings with FGID, ASD children with FGID and ASD without FGID were comparably higher (58-62 vs. 44, P siblings. There was no significant difference in ASD severity scores between ASD children with and without FGID. No significant difference in diversity or overall microbial composition was detected between ASD children with NT siblings. Exploratory analysis of the 16S rRNA sequencing data, however, identified several low abundance taxa binned at the genus level that were associated with ASD and/or first order ASD*FGID interactions (FDR <0.1).

    Full Text Available La transition du communisme vers le capitalisme dans les années 1990 en Hongrie dans le secteur de l’industrie cinématographique n’a pas été la rupture brutale qu’elle a pu être politiquement. Elle n’a pas non plus eu pour conséquence la facilité accrue en matière de production du film qu’on eût été en droit d’imaginer. Dans le présent article, je saisis le cas de Simon le mage, un film franco-hongrois de la réalisatrice Enyedi Ildikó sorti en 1998, pour analyser les modalités de cette transition et les nouvelles possibilités qui s’imposent pour les cinéastes afin de produire leurs œuvres. Dans cette culture de la coproduction due à l’ouverture de l’industrie à la loi du marché, les cinéastes doivent apprendre à composer avec les conséquences de l’arrivée soudaine du capitalisme dans un système préexistant. Ces difficultés se répercutent dans les œuvres, et mon approche historienne se double alors d’une approche esthétique afin de voir comment, dans ce film, la réalisatrice utilise Paris et la magie pour nous offrir son opinion sur les récents bouleversements en Hongrie.

  15. When co-action eliminates the Simon effect: disentangling the impact of co-actor's presence and task sharing on joint-task performance

    This study aimed at assessing whether the mere belief of performing a task with another person, who is in charge of the complementary part of the task, is sufficient for the so-called joint Simon effect to occur. In all three experiments of the study, participants sat alone in a room and underwent two consecutive Go/NoGo tasks that were identical except for the instructions. In Experiment 1, participants performed the task first individually (baseline task), and then either co-acting with another person who responded from an unknown location to the NoGo stimuli (joint task) or imaging themselves responding to the NoGo stimuli (imaginative task). Relative to the baseline, the instructions of the imaginative task made the Simon effect occur, while those of the joint task were ineffective in eliciting the effect. This result suggests that sharing a task with a person who is known to be in charge of the complementary task, but is not physically present, is not sufficient to induce the representation of an alternative response able to produce interference, which happens instead when the instructions explicitly require to imagine such a response. Interestingly, we observed that when the Simon effect was already present in the baseline task (i.e., when the response alternative to the Go response was represented in the individual task due to non-social factors), it disappeared in the joint task. We propose that, when no information about the co-actor's position is available, the division of labor between the participant and co-actor allows participants to filter out the possible (incidental) representation of the alternative response from their task representation, thus eliminating potential sources of interference. This account is supported by the results of Experiments 2 and 3 and suggests that under certain circumstances task-sharing may reduce the interference produced by the irrelevant information, rather than increase it.

  18. Geochemical and Mineralogical Evaluation of CO2-Brine-Rock Experiments: Characterizing Porosity and Permeability Variations in the Cambrian Mount Simon Sandstone

    The Cambrian Mount Simon Sandstone has been targeted as a major reservoir for carbon dioxide storage in the Illinois Basin. The Mount Simon Sandstone's geologic setting, mature quartz to arkosic composition, reservoir thickness, and overlying Eau Claire Formation seal make it an attractive candidate for long-term storage potential of carbon dioxide. Injection of carbon dioxide has been shown to cause a range of chemical alterations that causes dissolution of existing minerals and precipitation of secondary phases that can alter the porosity and permeability of the reservoir. This study focuses on using detailed microscopic analysis of two compositionally and texturally different Mount Simon Sandstone samples from the Illinois Basin that were experimentally exposed to CO2-rich brines for 6 months at the NETL in collaboration with the Indiana Geological Survey. Our objective was to examine the experimental samples to determine how post-experiment mineralogical and geochemical alterations relate to porosity and permeability variations. Gazzi-Dickinson point counting of Vermillion County samples adjacent to experimental sample depths (5805 ft) show that the sample contains an average of 78% quartz, 15% feldspar, 2% lithics, and 5% porosity. Point count data of Knox County samples from 8642.5, 8542, and 8642.2 show the experimental sample has an average of 70% quartz, 22% feldspar, 4% lithics, and 3.9% porosity. Both samples were submerged in carbon dioxide-saturated brine synthesized to match the measured geochemistry of Mount Simon Sandstone pore water for six months at 24MPa and 90 degrees to replicate sequestration conditions. The results of the experiment for the Vermillion County sample revealed a significant decrease in permeability and porosity. However the Knox County sample had a minor increase in permeability and porosity. Geochemical analyses (IC, ICP-MS, and ICP-OES) of brine geochemistry before and after the experiment show a decrease in pH and an increase

  19. Effects of laterality and pitch height of an auditory accessory stimulus on horizontal response selection: the Simon effect and the SMARC effect.

    In the present article, we investigated the effects of pitch height and the presented ear (laterality) of an auditory stimulus, irrelevant to the ongoing visual task, on horizontal response selection. Performance was better when the response and the stimulated ear spatially corresponded (Simon effect), and when the spatial-musical association of response codes (SMARC) correspondence was maintained-that is, right (left) response with a high-pitched (low-pitched) tone. These findings reveal an automatic activation of spatially and musically associated responses by task-irrelevant auditory accessory stimuli. Pitch height is strong enough to influence the horizontal responses despite modality differences with task target.

    A current challenge for decision-making research is in extending models of simple decisions to more complex and ecological choice situations. Conflict tasks (e.g., Simon, Stroop, Eriksen flanker) have been the focus of much interest, because they provide a decision-making context representative of everyday life experiences. Modeling efforts have led to an elaborated drift diffusion model for conflict tasks (DMC), which implements a superimposition of automatic and controlled decision activations. The DMC has proven to capture the diversity of behavioral conflict effects across various task contexts. This study combined DMC predictions with EEG and EMG measurements to test a set of linking propositions that specify the relationship between theoretical decision-making mechanisms involved in the Simon task and brain activity. Our results are consistent with a representation of the superimposed decision variable in the primary motor cortices. The decision variable was also observed in the EMG activity of response agonist muscles. These findings provide new insight into the neurophysiology of human decision-making. In return, they provide support for the DMC model framework.

    We used both the Extrinsic Affective Simon Task (EAST) and the Implicit Association Test (IAT) as implicit measures of inter-individual differences in attitudes towards political parties (Experiment 1), food items (Experiment 2) and homosexuality (Experiment 3). IAT but not EAST scores were related in a meaningful manner to self-report measures of the corresponding attitudes (Experiments 1-3) and self-reported behaviour (Experiments 2 and 3). Whereas split-half reliability of the IAT scores was satisfactory, EAST scores overall had a low split-half reliability. The present results suggest that the EAST as introduced by De Houwer (2003b, Experimental Psychology) does not offer a good alternative for the IAT as an implicit measure of inter-individual differences in attitudes.

    2007-03-01

    Full Text Available Scholarly data, such as academic articles, research reports and theses/dissertations, traditionally have limited dissemination in that they generally require journal subscription or affiliation with particular libraries. The notion of open access, made possible by rapidly advancing digital technologies, aims to break the limitations that hinder academic developments and information exchange. This paper presents the Electronic Thesis & Dissertation (ETD Project at the Simon Fraser University Library, British Columbia, Canada, and discusses various technological considerations associated with the Project including selection of software, capture of metadata, and long-term preservation of the digitized data. The paper concludes that a well-established project plan that takes into account not only technological issues but also issues relating to project policies, procedures, and copyright permissions that occur in the process of providing open access plays a vital role for the overall success of such projects.

Jahrhunderts gemeinsam widmet. In einer beinahe synoptisch anmutenden Herangehensweise fokussiert sie dabei auf den Begriff der Freiheit, der bei beiden von eminenter Bedeutung für das jeweilige Theoriegebäude ist. Holland-Cunz zufolge verstehen beide, bei einigen Unterschieden, Freiheit so, dass sie sich vor allem durch eine in sich eingeschriebene Gefährdung auszeichnet: Diese resultiert aus einem heroisch-emphatischen Gestus, der in paradoxer Weise gepaart wird mit einem abgeklärten Realismus. Über weite Strecken liest sich der Weg zu dieser Deutung, v. a. auch wegen einer teilweise sympathisch unkonventionellen und originellen Herangehensweise, sehr anregend und überzeugend.Barbara Holland-Cunz, who has already addressed Simone de Beauvoir and Hannah Arendt individually, dedicates this volume to both of these prominent thinkers of the 20th century. Using an almost synoptic approach, she focuses on the topic of freedom, which is of eminent importance for both of their theoretical structures. According to Holland-Cunz, both of them, despite some differences, understand freedom as signalized by a danger, which is inscribed within the very concept of freedom: this danger results from a heroic-emphatic gestus, which is paradoxically paired with serene realism. The way that Holland-Cunz pursues in order to reach her interpretation is very inspiring and convincing to read, particularly because of her often pleasantly unconventional and witty approach.

    This study explores the extent to which a bilingual advantage can be observed for three tasks in an established population of fully fluent bilinguals from childhood through adulthood. Welsh-English simultaneous and early sequential bilinguals, as well as English monolinguals, aged 3 years through older adults, were tested on three sets of cognitive and executive function tasks. Bilinguals were Welsh-dominant, balanced, or English-dominant, with only Welsh, Welsh and English, or only English at home. Card sorting, Simon, and a metalinguistic judgment task (650, 557, and 354 participants, respectively) reveal little support for a bilingual advantage, either in relation to control or globally. Primarily there is no difference in performance across groups, but there is occasionally better performance by monolinguals or persons dominant in the language being tested, and in one case-in one condition and in one age group-lower performance by the monolinguals. The lack of evidence for a bilingual advantage in these simultaneous and early sequential bilinguals suggests the need for much closer scrutiny of what type of bilingual might demonstrate the reported effects, under what conditions, and why.

    Full Text Available Abstract Introduction Acquired partial lipodystrophy or Barraquer-Simons syndrome is a rare form of progressive lipodystrophy. The etiopathogenesis of adipose tissue atrophy in these patients is unknown. Case presentation This is a case report of a 44-year-old woman with acquired partial lipodystrophy. To obtain insight into the molecular basis of lipoatrophy in acquired partial lipodystrophy, we examined gene expression in adipose tissue from this patient newly diagnosed with acquired partial lipodystrophy. A biopsy of subcutaneous adipose tissue was obtained from the patient, and DNA and RNA were extracted in order to evaluate mitochondrial DNA abundance and mRNA expression levels. Conclusion The expression of marker genes of adipogenesis and adipocyte metabolism, including the master regulator PPARγ, was down-regulated in subcutaneous adipose tissue from this patient. Adiponectin mRNA expression was also reduced but leptin mRNA levels were unaltered. Markers of local inflammatory status were unaltered. Expression of genes related to mitochondrial function was reduced despite unaltered levels of mitochondrial DNA. It is concluded that adipogenic and mitochondrial gene expression is impaired in adipose tissue in this patient with acquired partial lipodystrophy.

    Eight new species of Charinus Simon, 1892 are described for the Brazilian Amazon, from the states of Pará (C. bichuetteae sp. n., C. bonaldoi sp. n., C. carajas sp. n., C. ferreus sp. n., C. guto sp. n. and C. orientalis sp. n.) and Amazonas (Charinus brescoviti sp. n. and C. ricardoi sp. n.). All new species can be differentiated from the other species of the genus by the number of pseudo-articles in basitibia IV, the presence/absence of median eyes, and the shape of the female gonopod. Brazil now becomes the country with the largest diversity of Amblypygi in the world, with 25 known species. Half of the new species described here have a high degree of endangerment: C. bichuetteae sp. n. is threatened by the flood caused by the hydroelectric dam of Belo Monte, and C. carajas sp. n., C. ferreus sp. n. and C. orientalis sp. n. are endangered by the iron mining in Carajás municipality and surroundings. The Charinus species here described are endemic to the Amazon Region, so in order to assure their preservation, it is strongly recommended a special care with their habitats (type localities) which are facing increasing rates of destruction and deforestation.

    The aim of this study was to assess the efficacy of suction-assisted liposuction (SAL) in Simon grade 2b gynecomastia and its effect on sternal notch to nipple areola (SNN) distance. A retrospective analysis was performed on 21 patients with grade 2b gynecomastia who underwent SAL. Preoperative and postoperative SNN distances of the patients were measured, the results were analysed using a Mann-Whitney U test and a p-value point Likert scale was used to assess patient satisfaction with SAL surgery. All of the patients were followed up for an average period of 17.8 months (range = 12-28 months). The mean amount of lipoaspirate was 232 mL per breast (range = 190-310 mL). The mean preoperative SNN distance was 22.3 cm (range = 20-23.5 cm), whereas postoperative was 21.3 cm (range = 19.2-22.8 cm); the difference was statistically significant (p grade 2b gynecomastia and shortens the SNN distance by 1 cm, but further clinical studies are required to support this conclusion.

    A numerical model was developed to simulate reactive transport with porosity and permeability change of Mount Simon sandstone (samples from Knox County, IN) after 180 days of exposure to CO2-saturated brine under CO2 sequestration conditions. The model predicted formation of a high-porosity zone adjacent to the surface of the sample in contact with bulk brine, and a lower porosity zone just beyond that high-porosity zone along the path from sample/bulk brine interface to sample core. The formation of the high porosity zone was attributed to dissolution of quartz and muscovite/illite, while the formation of the lower porosity zone adjacent to the aforementioned high porosity zone was attributed to precipitation of kaolinite and feldspar. The model predicted a 40% permeability increase for the Knox sandstone sample after 180 days of exposure to CO2-saturated brine, which was consistent with laboratory-measured permeability results. Model-predicted solution chemistry results were also found to be consistent with laboratory-measured solution chemistry data. Initial porosity, initial feldspar content and the exponent n value (determined by pore structure and tortuosity) used in permeability calculations were three important factors affecting permeability evolution of sandstone samples under CO2 sequestration conditions. 1

  4. An analysis of England's nursing policy on compassion and the 6Cs: the hidden presence of M. Simone Roach's model of caring.

    2016-03-01

    In 2012, chief nursing officers (CNO) in England published a policy on compassion in response to serious criticisms of patients' care. Because their objective is fundamentally to shape nursing, this study argues, following Popper, that the policy should be analysed. An appraisal tool, developed from Popper, Gadamer, Jauss and Thiselton, is the framework for this analysis. The CNO policy document identified six values and behaviours, termed '6Cs', required by all nurses, midwives and care staff. The document contains no data, references or acknowledgements, but is similar to the 6Cs defined by the Canadian nursing nun, Sister M. Simone Roach, in her theory of caring published 30 years earlier. Roach considered caring and the components of it, including compassion, to be moral virtues, an inner motivation to care. This study suggests that without explicit reference to Roach's ideas, and her underlying theoretical base, the CNO requirement has the effect of turning virtues into commodities and a form of external control, described by Ritzer as a McDonaldized dehumanization. This study, which has international relevance beyond England and the UK, suggests that the CNO revise their policy by acknowledging Roach's 6Cs and openly discuss the implications of her work for their policy. © 2015 John Wiley & Sons Ltd.

  5. The role of social cues in the deployment of spatial attention: Head-body relationships automatically activate directional spatial codes in a Simon task

    Full Text Available The role of body orientation in the orienting and allocation of social attention was examined using an adapted Simon paradigm. Participants categorized the facial expression of forward facing, computer-generated human figures by pressing one of two response keys, each located left or right of the observers’ body midline, while the orientation of the stimulus figure’s body (trunk, arms, and legs, which was the task-irrelevant feature of interest, was manipulated (oriented towards the left or right visual hemifield with respect to the spatial location of the required response. We found that when the orientation of the body was compatible with the required response location, responses were slower relative to when body orientation was incompatible with the response location. This reverse compatibility effect suggests that body orientation is automatically processed into a directional spatial code, but that this code is based on an integration of head and body orientation within an allocentric-based frame of reference. Moreover, we argue that this code may be derived from the motion information implied in the image of a figure when head and body orientation are incongruent. Our results have implications for understanding the nature of the information that affects the allocation of attention for social orienting.

    Cognitive control in response compatibility tasks is modulated by the task context. Two types of contextual modulations have been demonstrated; sustained (block-wise) and transient (trial-by-trial). Recent research suggests that these modulations have different underlying mechanisms. This study presents new evidence supporting this claim by comparing false alarm (FA) responses on no-go trials of the Simon task between the sustained and transient contexts. In Experiment 1, the sustained context was manipulated so that a block included a larger number of incongruent trials. Results showed that participants made more FA responses by the hand opposite to the stimulus location. This suggests a generation of response bias in which the task-irrelevant location information is utilized in a reversed manner (i.e., to respond with the right hand to a stimulus presented on the left side and vice versa). Next, Experiment 2 examined the effect of the transient context and found that overall FA rate was lower when a no-go trial was preceded by an incongruent trial than by a congruent trial, whereas such response bias as that shown in Experiment 1 was not demonstrated. This suggests that the transient conflict context enhances inhibition of the task-irrelevant process but does not make the task-irrelevant information actively usable. Based on these results, we propound two types of cognitive control modulations as adaptive behaviors: response biasing based on utilization of the task-irrelevant information under the sustained conflict context and transient enhancement of inhibition of the task-irrelevant process based on the online conflict monitoring.

    Dyl et al. (2011) state that their results confirm the conclusion of J. Simon et al. (2005) that the pyroxene in Wark-Lovering rims (Wark and Lovering, 1977) found on Ca-, Al-rich refractory inclusions has lower Ti3+/Titot ratios than the primary pyroxene in the interiors of inclusions. While true, the claim is misleading because J. Simon et al. (2005) concluded that there was no Ti3+ in the rims, whereas Dyl et al. (2011) found Ti3+ in 41 of 42 new rim analyses. In addition, J. Simon et al. (2005) concluded that rims formed under much more oxidizing conditions, log fO2 ⩾ IW-1, or ⩾6-7 log units higher, than inclusion interiors. The conclusions of J. Simon et al. (2005) were disputed by S. Simon et al. (2007) and are not supported by the new data of Dyl et al. (2011). The present work is intended for clarification of this and other issues.

    An increasing number of studies have shown a close link between perception and action, which is supposed to be responsible for the automatic activation of actions compatible with objects' properties, such as the orientation of their graspable parts. It has been observed that left and right hand responses to objects (e.g., cups) are faster and more accurate if the handle orientation corresponds to the response location than when it does not. Two alternative explanations have been proposed for this handle-to-hand correspondence effect: location coding and affordance activation. The aim of the present study was to provide disambiguating evidence on the origin of this effect by employing object sets for which the visually salient portion was separated from, and opposite to the graspable 1, and vice versa. Seven experiments were conducted employing both single objects and object pairs as visual stimuli to enhance the contextual information about objects' graspability and usability. Notwithstanding these manipulations intended to favor affordance activation, results fully supported the location-coding account displaying significant Simon-like effects that involved the orientation of the visually salient portion of the object stimulus and the location of the response. Crucially, we provided evidence of Simon-like effects based on higher-level cognitive, iconic representations of action directions rather than based on lower-level spatial coding of the pure position of protruding portions of the visual stimuli.

    The Ensenada de San Simon is the inner part of the Ria de Vigo, one of the major mesotidal rias of the Galician coast, NW Spain. The geochemistry of its bottom sediments can be accounted for in terms of both natural and anthropogenic sources. Mixture-modelling enables much of the Cr, Ni, V, Cu, Pb and Zn concentrations of the bottom and subaqueous sediments to be explained by sediment input from the river systems and faecal matter from manmade mussel rafts. The compositions and relative contributions of additional, unknown, sources of anomalous heavy-metal concentrations are quantified using constrained nonlinear optimization. The pattern of metal enrichment is attributed to: material carried in solution and suspension in marine water entering the Ensenada from the polluted industrial areas of the adjacent Ria de Vigo; wind-borne urban dusts and/or vehicular emissions from the surrounding network of roads and a motorway road-bridge over the Estrecho de Rande; industrial and agricultural pollution from the R. Redondela; and waste from a former ceramics factory near the mouth of the combined R. Oitaben and R. Verdugo. Using {sup 137}Cs dating, it is suggested that heavy metal build-up in the sediments since the late 1970s followed development of inshore fisheries and introduction of the mussel rafts (ca. 1960) and increasing industrialisation.

    The Monte Carlo method was used to simulate an equilibrium diagram, and structural formation of transformation and recrystallization. In simulating the Cu-A equilibrium diagram, the calculation was performed by laying 24 face centered cubic lattices including four lattice points in all of the three directions, and using a simulation cell consisting of lattice points of a total of 24{sup 3}{times}4 points. Although this method has a possibility to discover existence of an unknown phase as a result of the calculation, problems were found left in handling of lattice mitigation, and in simulation of phase diagrams over phases with different crystal structures. In simulation of the transformation and recrystallization, discussions were given on correspondence of 1MCS to time when the lattice point size is increased, and on handling of nucleus formation. As a result, it was estimated that in three-dimensional grain growth, the average grain size is proportional to 1/3 power of the MCS number, and the real time against 1MCS is proportional to three power of the lattice point size. 11 refs., 8 figs., 2 tabs.

We show how normative valuation models should rather be viewed as forms of reality representation, frameworks according to which the real world is perceived, fragmented for a better understanding, and recomposed, providing an orderly method for undertaking a task as complex as the investment decision.

    Even in its extended usage, the concept of bounded rationality bears the birthmark of its origins in economics. First and most obviously, it is about seeking the most efficient (not necessarily the best) means toward a given end, whether that is curing patients or proving theorems. Second, the means are whittled down to the most parsimonious possible, not only acknowledging cognitive limitations but actually imposing them, whether in the form of Morgan's canon, Methodist agnosticism about causes, or Entscheidungsproblem-like restrictions on the acceptable formulation of mathematical proofs. Third, these parsimonious restrictions all tend to minimize the role of reasonable deliberation in rationality, albeit in different ways. As an object of inquiry for the history of science, bounded rationality has great promise. But as a model of the history of science, as one long exercise in bounded rationality, its utility may apply more to future than past science.

    The purpose of this paper is to bring to light that specific persons occupied to tranfer into the Greek era the ideas of Saint-Simon, after his death in 1825. Saint-Simon's name and doctrines were known to the Greek scholars of the Diaspora and especially to Corais' circle. One of the most active Corais' disciples, Fr. Pylarinos (1802-1882) adopted the doctrines of the Saint-Simonists and propagated and presented them in the above newspaper "Helios". In 1833, when King Otho cam...

    Full Text Available In this article we analyse one of the most fascinating paradoxes of mass politics. Based on the data from the studies of neurobiologists, neurologists, social psychology, cognitive and evolution studies we answer the question specified in literature as the Simon’s puzzle: How is it possible that citizens have their opinions about politics, if they know so little about it? We began our analysis from the criticism of the economic rationality approach. To do this, we referred to the Allais paradox, cognitive dissonance theory, Ellsberg paradox, the concept of bounded rationality, conjunction fallacy and prospect theory. Next, we described the evolutionary processes shaping the minds of Homo sapiens and characterised cognitive mechanisms, thanks to which people can make political choices, especially in view of the shortage of time and information. The following heuristics are referred to herein: affect, recognition, judgment and imitation.

    Full Text Available Simón Bolívar, uma das lideranças mais importantes das independências na América do Sul de colonização espanhola, deixou um epistolário com 2815 cartas. Ao partir do propósito em expor o projeto narrativo epistolar, um dos temas de destaque, no decorrer da leitura, foi o da renúncia do general. As diversas solicitações de renúncia ao cargo administrativo e as justificativas que as acompanhavam levaram-me à análise do que denominei por memória da indispensabilidade. Depois da investigação desse discurso no epistolário, as relações com a literatura e a biografia foram fundamentais para ampliar a compreensão acerca da composição dessa memória da indispensabilidade nas epístolas. Para este artigo, pretende-se cotejar as cartas de Simón Bolívar e o romance de Gabriel García Márquez, O General em seu labirinto. A hipótese é a de que o texto literário, além de usar o epistolário bolivariano para construir seu personagem e a cena romanesca, acrescenta possibilidades explicativas sobre o projeto de memória conduzido pela escrita de cartas, na mesma medida em que reforça o culto ao general Libertador.Simon Bolivar, one of the most important South American leaders of independence within the areas of Spanish colonialism in South America, left behind an epistolary of 2815 letters. Our proposal starts off with the display of the narrative epistolary project and soon encounters one of its highlights in the course of the reading, which is the general's own resignation. The several requests of resignation from his administrative position, and the justifications that followed them had taken me to the analysis of what I called the memory of the indispensability. After investigating this speech in the epistolary, the relationship between literature and the biography had been fundamental in improving our understanding of the substance of this memory of the indispensability in the epistles. This article intends to compare Simon

The first generation process begun in 1973, called the Thiosorbic® Process, was a technical breakthrough that offered significantly improved operating and performance characteristics compared with competing FGD technologies. The process is described as Flow Diagram "A" in Figure 1. A disadvantage of this and other inhibited or natural oxidation wet FGD systems is the capital and operating cost associated with landfill disposal of the calcium sulfite based solids. Fixation to stabilize the sludge solids for compunction in a landfill also consumes fly ash that otherwise may be marketable.

    The extraction equilibria (i.e., distribution ratio) of amino acids by Di (2-ethyl hexyl) phosphoric acid in n-heptane solutions was investigated at a temperature of 298.2 K in the low pH range (of 2 to 5). The equal amount of an amino acid solution and an extracted solution with the predetermined concentration were shaken using a flask, and the concentration of amino acid in water phase was analyzed by a ninhydrin method. The concentration in organic phase was obtained by the concentration analysis in water phase and the material balance method after the amino acid is back-extracted by solution hydrochloride. The distribution ratio is in inverse proportion to the hydrogen ion concentration and in proportion to the 0.5th power of extracted agent concentration. The equilibrium constant is 0.650, 0.420, 0.320, 0.275, 0.064, and 0.040 mol{sup 0.5}/m{sup 1.5} in L-phenylalanine, L-tryptophane, L-leucine, L-methionine, glycine, and L-alanine, respectively. The equilibrium constant of the largest L-phenylalanine is 16 times as high as the smallest alanine. The extracted equilibrium constant increased as the hydrophobic property of amino acid increases. 18 refs., 10 figs., 1 tab.

    Vapor-liquid equilibria of aqueous ethanol solutions containing a minute amount of acetaldehyde, isobutyraldehyde, ethyl acetate and isoamyl acetate were measured by use of an Othmer-type still at 12.7, 25.3 and 101.3 kPa. The equilibrium ratio curves of the minor components (isobutyraldehyde, ethyl acetate and isoamyl acetate) at each pressure are presented by a function of the concentration of ethanol. However, the equilibrium ratio curves of the minor component (acetaldehyde) could not be obtained, because the data is slightly scatted. 5 refs., 3 figs., 2 tabs.

    Full Text Available While Beauvoir admitted that feminists refused to be women-alibi as she had been, Irigaray recognized that she was one of the many who had read The Second sex being reanimated by it. Nevertheless the two authors have been considered the reference of two opposite feminist theoretical and political paradigms, again and again – emancipation vs liberation, constructivism vs essentialism, materialism vs symbolical. Through the rereading of their main issues, a new feminist paradigm can be developed for the contemporary challenges.

    Full Text Available After the description in the 19th century of two hummingbird species currently allocated to the genus Stephanoxis, Peters (1945 merged both taxa into a single species without providing any rationale. Here we re-evaluate the taxonomy and species limits of the representatives of this genus based on an extensive number of specimens. We demonstrate these taxa are better treated as full species under both the Biological and Phylogenetic Species Concepts due to their well-defined range and plumage patterns and reciprocally diagnosability. They have distinct, allopatric distributions segregated by a 160 km gap between the Serra do Mar, to the east, and Serra de Paranapiacaba, to the west, in the state of São Paulo. Stephanoxis species have ranges which are congruent with other montane bird species’ suggesting shared vicariance events during preterit interglacial periods.

    We wouldn't like to bring up discrimination, but the tone of the commentary, which does not contain any science-based criticism or any alternative suggestions, does make one think of an unduly disrespectful attitude both towards the Russian participants and the project on radiative neutron decay itself. Here we cite our response to the commentary of our Western collaborants to the article printed in JETP Letters 83(1) p.5. We remain firm in the positions published in this article. In our last experiment we measured the relative intensity of radiative neutron decay (B.R.=(3.2+-1.6) 10-3 with C.L.=99.7% and lower energy limit of radiative gamma-quanta measured equal to 35 KeV) .

Los hechos y los mitos (Vol. I, así como sobre algunos de sus principales supuestos y aportes a la contemporaneidad. El recorrido a realizar abarca desde su concepción de la alteridad, la crítica a la biología, el psicoanálisis y el materialismo; la evolución histórica de las mujeres hasta la interconexión con el presente siglo. Sus páginas cuestionan, develan y denuncian con exquisita maestría el papel asignado a las mujeres en la sociedad, y con ello, la infl uencia de los valores culturales en la “construcción” de lo femenino. Sus luces han posibilitado un salto cualitativo en el análisis, visión y perspectivas en el estudio y comprensión ética y política de las mujeres, como también de su camino hacia la liberación. AbstractThis research focuses on one of the fi nest works of feminist thought, The second sex. Facts and myths (Vol. I, as well as some of its key assumptions and inputs to the contemporary. The tour begins from conception of otherness, the critique to the biology, psychoanalysis, materialism and the historical evolution of women up to the connection with the present century. Its pages question, reveal, denounce, with exquisite skill, the role assigned to the women in society, and thus, the infl uence of cultural values in the “construction” of the feminine. Their influence enabled a quantum leap in the analysis, insight and perspective in the study and understanding of female ethics and politics, as well as its path to liberation.

    2017-03-01

    Full Text Available An efficient management of education in the 21st century requires that educational institutions not only promote the use of Information and Communication Technologies (ICT, but also manage strategic changes in the organization that facilitate the adaptation of this to the educational demands of the century XXI. In this context, this article tries to formulate, from the findings of a fieldwork, some considerations of educational management for the integration of policies in favor of the use of ICT in the Simón Bolívar University. As theoretical references is taken into account the model TPACK, formulated by XXX and the "connectivist" system formulated by Siemens, which gives account of a "new way of learning" with the use of technologies. From a holistic point of view, it takes into account the study by competences in the curricula.

  16. Subverting the Dominant Order: Narrative as Weapon in Simone de Beauvoir's Tous les hommes sont mortels

    Directory of Open Access Journals (Sweden)

    Barbara Klaw

    1996-06-01

    Full Text Available This essay argues that through the narrative techniques of point of view and embedding, Beauvoir carefully constructed her narrative and those of her male and female characters in Tous les hommes sont mortels , her third novel, published in 1946, in order to explain why males dominate society and to encourage women to fight against the current patriarchal social order. Many critics view Fosca as the principal character, and his 400-page embedded recapitulation of his past as the predominant text, but shifting the focus from Fosca to Régine, who constitutes the only focalizer of present events in the embedding text, clarifies many details previously judged as faults. This study advances that the awkwardness of the characters and of the linking of the narrative strands needs to be reinterpreted in relation to thematic repetitions and contradictions, the narrator's reliability, the use of time, psychoanalytic theory, the author's life at the time of writing, cultural history, and theories concerning énonciation . The interplay of these elements indicates the ways in which narrative is wielded as a weapon which ultimately promotes female independence in the struggle between the sexes.

    Abstract Background Current human resources planning models in nursing are unreliable and ineffective as they consider volumes, but ignore effects on quality in patient care. The project RN4CAST aims innovative forecasting methods by addressing not only volumes, but quality of nursing staff as well as quality of patient care. Methods\\/Design A multi-country, multilevel cross-sectional design is used to obtain important unmeasured factors in forecasting models including how features of hospital work environments impact on nurse recruitment, retention and patient outcomes. In each of the 12 participating European countries, at least 30 general acute hospitals were sampled. Data are gathered via four data sources (nurse, patient and organizational surveys and via routinely collected hospital discharge data). All staff nurses of a random selection of medical and surgical units (at least 2 per hospital) were surveyed. The nurse survey has the purpose to measure the experiences of nurses on their job (e.g. job satisfaction, burnout) as well as to allow the creation of aggregated hospital level measures of staffing and working conditions. The patient survey is organized in a sub-sample of countries and hospitals using a one-day census approach to measure the patient experiences with medical and nursing care. In addition to conducting a patient survey, hospital discharge abstract datasets will be used to calculate additional patient outcomes like in-hospital mortality and failure-to-rescue. Via the organizational survey, information about the organizational profile (e.g. bed size, types of technology available, teaching status) is collected to control the analyses for institutional differences. This information will be linked via common identifiers and the relationships between different aspects of the nursing work environment and patient and nurse outcomes will be studied by using multilevel regression type analyses. These results will be used to simulate the impact of changing different aspects of the nursing work environment on quality of care and satisfaction of the nursing workforce. Discussion RN4CAST is one of the largest nurse workforce studies ever conducted in Europe, will add to accuracy of forecasting models and generate new approaches to more effective management of nursing resources in Europe.

    A mi modo de ver, la tesis de Weil de la existencia de una verdad universal en una pluralidad de culturas resulta ser una aportación al problema del diálogo intercultural e interreligioso, que merece ser considerada en tanto supone una postura que difícilmente encuentra parangón. Una convivencia auténtica de los seres humanos y sus sociedades pasa irremisiblemente, a ojos de esta pensadora, por el esfuerzo siempre renovado de hacer lo imposible por realizar la verdad en la vida individual y c...

    1999-01-01

    Full Text Available What is true, beautiful, and good? Using the theory of evolution, the musical genius of Mozart, and the horrors of the Holocaust, Howard Gardner, in The Disciplined Mind successfully assists students' and teachers' cultural understanding of their educational process as it relates to truth, beauty, and goodness. He does this by emphasizing that we should teach less but in more depth. By probing important issues in depth, we will be teaching much more. In pursuit of truth, Gardner links Darwin's development of systematic classification of living organisms to the understanding of topics that effect human beings today. In doing so, he manages to fmd common ground between the scientific and religious communities, despite the controversies surrounding the theory of evolution. He uses the power of music to depict the human condition in Mozart's work, "The Marriage of Figaro," in search of beauty as it appears in music and human relations. And, in pursuit of the good (and the ugly, Gardner uses the Holocaust and the atrocities associated with it, as a way to understand, not only the Holocaust, but also the human motivation behind such a horrific and elaborate endeavour

    2002-01-01

    We start from a parity-breaking MCS QED sub 3 model with spontaneous breaking of the gauge symmetry as a framework for evaluation of the electron-electron interaction potential and for attainment of numerical values for the e sup - e sup - - bound state. Three expressions V sub e sub f sub f subarrow down subarrow down, V sub e sub f sub f subarrow down subarrow up, V sub e sub f sub f subarrow down subarrow down) are obtained according to the polarization state of the scattered electrons. In an energy scale compatible with condensed matter electronic excitations, these potentials become degenerated. The resulting potential is implemented in the Schroedinger equation and the variational method is applied to carry out the electronic binding energy. The resulting binding energies in the scale of 10-100 meV and a correlation length in the scale of 10 - 30 Angstrom are possible indications that the MCS-QED sub 3 model adopted may be suitable to address an eventual case of e sup - e sup - pairing in the presence o...

    Full Text Available Il volume nasce da un percorso di progettazione partecipata condotto da una rete provinciale di scuole di ogni ordine e grado, le quali hanno scelto di assumersi la responsabilità di esercitare un ruolo attivo nel fronteggiamento dei problemi educativi posti dalla società postmoderna e globalizzata. L’educazione interculturale si prospetta dunque come la risposta più avanzata rispetto alle modificazioni sociali nazionali, europee e mondiali e alla conseguente domanda di istruzione e formazione di ogni persona e della collettività. Essa non è la risposta ad un’emergenza legata ai fenomeni migratori, quanto semmai l’occasione di promuovere una convivenza basata sulla cooperazione, lo scambio, l’accettazione produttiva delle diversità come valori e opportunità di crescita democratica. Ogni scuola - questa è la tesi di fondo del volume - è chiamata a divenire un laboratorio ove si apprende a convivere costruttivamente con le differenze sperimentando nel concreto la cittadinanza planetaria.

The program predicts enhanced division frequencies after a period of slow replication under thymine limitation if a minimal distance (Eclipse exists between successive replisomes, as observed. Missing features and ways to improve, extend and refine CCSim are proposed, for both single cells and random populations under steady-states of exponential growth and during well-defined transitions. Future improvements and extensions are proposed for single cells and populations.

    Performing a task alone or together with another agent can produce different outcomes. The current study used event-related functional magnetic resonance imaging (fMRI) to investigate the neural underpinnings when participants performed a Go/Nogo task alone or complementarily with another co-actor (unseen), whom was believed to be another human or a computer. During both complementary tasks, reaction time data suggested that participants integrated the potential action of their co-actor in their own action planning. Compared to the single-actor task, increased parietal and precentral activity during complementary tasks as shown in the fMRI data further suggested representation of the co-actor’s response. The superior frontal gyrus of the medial prefrontal cortex was differentially activated in the human co-actor condition compared to the computer co-actor condition. The medial prefrontal cortex, involved thinking about the beliefs and intentions of other people, possibly reflects a social-cognitive aspect or self-other discrimination during the joint task when believing a biological co-actor is present. Our results suggest that action co-representation can occur even offline with any agent type given a priori information that they are co-acting; however, additional regions are recruited when participants believe they are task-sharing with another human.

    2011-01-01

    Full Text Available Beauvoir’s work was translated in 1969, a period of change in state socialism: the introduction of some elements of market economy in 1968 (called New Economic Mechanism, the publication of Western bourgeois philosophers as Sartre and Beauvoir, and Marxist philosophers’ efforts to revise orthodox Marxism. ’The woman question’ was declared to be already solved by socialism. The emblematic female identity is of the working mother: free and equal with men by virtue of law, taking part in producing new value as worker and according to her natural role as mother and wife, representing the center of the socialist family. Under these circumstances the reception of The Second Sex is highly interesting: a success (two editions in a high number of copies, but only two contemporary reviews (one friendly, one sharply critical. In this paper, I give a reconstruction of socialist women’s reading of Beauvoir, given their officially propagated homogeneous identity and their unrecognized double burden. They could have identified themselves with Beauvoir’s new, independent woman and at the same time with the traditional woman. Beauvoir’s legacy for us post-socialist women can be derived from this past: to face ambiguities in identity and to vindicate individual freedom.

    We define and discuss classical and quantum gravity in 2+1 dimensions in the Galilean limit. Although there are no Newtonian forces between massive objects in (2+1)-dimensional gravity, the Galilean limit is not trivial. Depending on the topology of spacetime there are typically finitely many topological degrees of freedom as well as topological interactions of Aharonov-Bohm type between massive objects. In order to capture these topological aspects we consider a two-fold central extension of...

  20. Towards a common theory for learning from reward, affect, and motivation: The SIMON framework

    Directory of Open Access Journals (Sweden)

    Christopher R Madan

    2013-10-01

    Full Text Available While the effects of reward, affect, and motivation on learning have each developed into their own fields of research, they largely have been investigated in isolation. As all three of these constructs are highly related, and use similar experimental procedures, an important advance in research would be to consider the interplay between these constructs. Here we first define each of the three constructs, and then discuss how they may influence each other within a common framework. Finally, we delineate several sources of evidence supporting the framework. By considering the constructs of reward, affect, and motivation within a single framework, we can develop a better understanding of the processes involved in learning and how they interplay, and work towards a comprehensive theory that encompasses reward, affect, and motivation.

    2005-11-01

    Full Text Available Aus Anlass des 50jährigen Jubiläums der Erstausgabe von Das andere Geschlecht haben namhafte Wissenschaftlerinnen aus den Gebieten Philosophie, Biologie, Soziologie, Psychoanalyse, Geschichte und Literatur das fast tausendseitige Standardwerk des Feminismus einer akribischen Lektüre unterzogen und dabei versucht, jene Fragen zu rekonstruieren, auf die das Werk bei seinem Erscheinen im Jahr 1949 eine Antwort gab. Die zeitlos scheinende Formel von der Konstruiertheit weiblicher Identität sollte wieder in ihren ursprünglichen Entstehungszusammenhang gestellt, die Autorin aus der mythischen Ferne in die kritische Nähe gerückt werden. Diese kritischen Lektüren sind insgesamt gut dokumentiert und erlauben meines Wissens zum ersten Mal einen Einblick in die Beauvoirsche Werkstatt. Ein weiterer – ebenfalls von Ingrid Galster herausgegebener – Band dokumentiert die Reaktionen, die unmittelbar nach Erscheinen von Le deuxième sexe in der französischen Presse erschienen sind.In celebration of the 50-year anniversary of the first edition of The Second Sex, well-known scholars from the fields of philosophy, biology, sociology, psychoanalysis, history, and literature have meticulously read the almost one-thousand-page standard work of feminism. In doing so, they have attempted to reconstruct those questions to which the work provided an answer at the time of its publication in the year 1949. The seemingly timeless formula of the constructed nature of feminine identity is placed in its original context and the author brought from the mythological distance to close critical proximity. These critical readings are overall well documented and allow a first glimpse, to my knowledge, into de Beauvoir’s workshop. A second volume—also edited by Ingrid Galster—documents the reactions that appeared in the French press at the time of the first publication of The Second Sex.

    Full Text Available A new species of Charinus is described from Israel and new localities for C. ioanniticus are reported. Charinus israelensis sp. nov. is a cave dwelling species with extremely small median eyes, no median tubercle and reduced lateral eyes. It is similar to C. ioanniticus, which occurs in nearby areas, but can be differentiated by the shape of the carapace, the number of pedipalp spines and the development of the eyes. A detailed comparison is made between the two species, including pictures, drawings and scanning electron micrographs. Charinus ioanniticus is reported here from several new localities in Israel and Turkey. Identification keys to the Charinus species groups and to the species of the bengalensis group are provided.

  6. Disturbance of Native Americans as Reflected in Selected Folkloric Poems of Luci Tapahonso, Joy Harjo and Simon Ortiz

    Directory of Open Access Journals (Sweden)

    Widad Allawi Saddam

    2016-12-01

    Full Text Available As a result of colonialization  and assimilation, the natives were disturbed between past and present. Adopting the colonizer culture, style of life, language and changing home place come together in the mind of Native American people and lead them to be confused; they intermingle between past and present. They want to be themselves but the colonizer wants them to be the others. This feeling of disturbance affected Native American people, especially the chosen poets for this study. This paper shows how Native American people reflect their disturbance toward the colonization in their folkloric poetry. It explains how each element of folklore represents their disturbance towards the colonizer’s dominant culture. This paper will be done under postcolonial framework utilizing Frantz Fanon’s second views about the natives. Disturbance follows assimilation and they together forced Native Americans to present fighting literature which shows the third phase of Fanon.

  7. Testing Chern-Simons Modified Gravity with Gravitational-Wave Detections of Extreme-Mass-Ratio Binaries

    CERN Document Server

    Canizares, Priscilla; Sopuerta, Carlos F

    2012-01-01

    [abridged] The detection of gravitational waves from extreme-mass-ratio (EMRI) binaries, comprising a stellar-mass compact object orbiting around a massive black hole, is one of the main targets for low-frequency gravitational-wave detectors in space, like the Laser Interferometer Space Antenna (LISA or eLISA/NGO). The long-duration gravitational-waveforms emitted by such systems encode the structure of the strong field region of the massive black hole, in which the inspiral occurs. The detection and analysis of EMRIs will therefore allow us to study the geometry of massive black holes and determine whether their nature is as predicted by General Relativity and even to test whether General Relativity is the correct theory to describe the dynamics of these systems. To achieve this, EMRI modeling in alternative theories of gravity is required to describe the generation of gravitational waves. In this paper, we explore to what extent EMRI observations with LISA or eLISA/NGO might be able to distinguish between G...

    2005-11-01

    Full Text Available Aus Anlass des 50jährigen Jubiläums der Erstausgabe von Das andere Geschlecht haben namhafte Wissenschaftlerinnen aus den Gebieten Philosophie, Biologie, Soziologie, Psychoanalyse, Geschichte und Literatur das fast tausendseitige Standardwerk des Feminismus einer akribischen Lektüre unterzogen und dabei versucht, jene Fragen zu rekonstruieren, auf die das Werk bei seinem Erscheinen im Jahr 1949 eine Antwort gab. Die zeitlos scheinende Formel von der Konstruiertheit weiblicher Identität sollte wieder in ihren ursprünglichen Entstehungszusammenhang gestellt, die Autorin aus der mythischen Ferne in die kritische Nähe gerückt werden. Diese kritischen Lektüren sind insgesamt gut dokumentiert und erlauben meines Wissens zum ersten Mal einen Einblick in die Beauvoirsche Werkstatt. Ein weiterer – ebenfalls von Ingrid Galster herausgegebener – Band dokumentiert die Reaktionen, die unmittelbar nach Erscheinen von Le deuxième sexe in der französischen Presse erschienen sind.

    2013-03-01

    The Iowa Stored Energy Plant Agency selected a geologic structure at Dallas Center, Iowa, for evaluation of subsurface compressed air energy storage. The site was rejected due to lower-than-expected and heterogeneous permeability of the target reservoir, lower-than-desired porosity, and small reservoir volume. In an initial feasibility study, permeability and porosity distributions of flow units for the nearby Redfield gas storage field were applied as analogue values for numerical modeling of the Dallas Center Structure. These reservoir data, coupled with an optimistic reservoir volume, produced favorable results. However, it was determined that the Dallas Center Structure cannot be simplified to four zones of high, uniform permeabilities. Updated modeling using field and core data for the site provided unfavorable results for air fill-up. This report presents Sandia National Laboratories petrologic and petrophysical analysis of the Dallas Center Structure that aids in understanding why the site was not suitable for gas storage.

    A study was made of 20 cilia and sebum from 20 nasal follicles from each of 86 persons. In a normomaterial aged 20-30 years. Demodex folliculorum was present in the nasal follicles in 25% and in the cilia in 29% of the subjects. This is consistent with the very high incidence we found 10 years ago. Systemic erythromycin treatment did not erradicate the mite, but the incidence decreased in both regions. Systemic glucocorticoid treatment lowered the incidence in the nasal region, whereas the incidence increased in the ciliary region.

Teigiama, kad dėl bū­dingo baroko menui ypatingo dėmesio tradicijai kūry­binė kompetencija sutapo su recepcine kompetencija, tiesa – su metodu.

    Full Text Available Il manuale realizzato dal Parco Nazionale della Majella, IZS di Lazio e Toscana, Corpo Forestale dello Stato e Legambiente, è il primo tentativo di tracciare un percorso condiviso nell'ambito delle investigazioni per i reati contro gli animali. Le attività di bracconaggio o di uccisione illegale di animali, infatti, rappresentano ancora oggi un fenomeno tristemente attuale nel nostro Paese; si pensi ai tanti lupi uccisi per avvelenamento o attraverso lacci e armi da fuoco. Gli autori del manuale, realizzato con il cofinanziamento della CE nell'ambito del progetto Life Wolfnet "Development of coordinated protection measures for Wolf in Apennines", sono medici veterinari che ben conoscono la materia, a partire dal dott. Rosario Fico che dirige il Centro di Referenza Nazionale per la Medicina Forense Veterinaria dell'IZS di Lazio e Toscana. La pubblicazione nasce da un progetto, teso alla conservazione e gestione coordinata del Lupo nell'Appennino, che in primis ha messo in atto azioni dirette a ridurre il conflitto verso il lupo conseguente a sistemi normativi e procedurali di indennizzo del danno insufficienti, per poi combattere l'ostilità nei suoi confronti da parte degli allevatori e delle comunità locali. Sono state inoltre intraprese azioni per contrastare il fenomeno della mortalità illegale, ridurre la persistenza di rischi o lo sviluppo di nuove criticità sanitarie per la popolazione di lupo. Il progetto ha infine avviato attività finalizzate alla riduzione del disturbo diretto o indiretto al lupo e l'attivazione di un Network istituzionale. Il manuale è strutturato in 8 capitoli: Normativa essenziale; Ruoli e competenze; La scena del crimine; Dopo la scena del crimine; Il video-foto-trappolaggio come strumento di prevenzione e di indagine; Casi studio; Procedura operativa per la necroscopia del lupo; Modulistica. Da segnalare i contributi di Rita Lorenzini e Antonio Antonucci che si aggiungono ai tre autori principali.

    Control of S02 emission from coal combustion requires desulfurization of coal before its combustion to produce coal refuse. Alternatively, gaseous emissions from coal combustion may be scrubbed to yield flue gas desulfurization (FGD) by-products that include calcium sulfite (CaSO3∙0.5H2O or simply CaS03). Acid production in coal refuse due to pyrite oxidation and disposal of large amounts of FGD can cause environmental degradation. Addition of CaS03 and CaS03-containing FGD to coal refuse may reduce the amounts of oxygen and ferric ion available to oxidize pyrite because the sulfite moiety in CaS03 is a strong reductant and thus may mitigate acid production in coal refuse. In Chapter 1, it was shown that CaS03 efficiently scavenged dissolved oxygen and ferric ion in water under the conditions commonly encountered in a coal refuse disposal environment. In the presence ofCaS03, the concentration of dissolved oxygen in water exposed to the atmosphere declined to below 0.01 mg L"1 at pH <8.0. In Chapter 2, it was demonstrated that CaS03 prevented a pH drop in coal refuse slurry when 0.2 gCaS03 was added to a 2% fresh coal refuse slurry every three days. Calcium sulfite also inhibited acid leaching from fresh coal refuse in bench-scale columns under controlled conditions. During the initial 13 weeks of leaching, the total amounts of titratable acidity, soluble H\\ Fe, and Al from CaS03-treated refuse (6.4 gin 50 g fresh coal refuse) were only 26%,10%, 32%, and 39% of those of the control columns, respectively. A combination of CaS03 with CaC03 or fly ash enhanced the inhibitory effect of CaS03 on acid leaching. Calcium sulfite-containing FGD which combined CaS03, CaC03, fly ash, and gypsum showed a much stronger inhibitory effect on acid leaching than CaS03 alone. This combination effect was partially due to the positive interaction of CaS03 with CaC03 and fly ash on inhibition of acid leaching. In Chapter 3, CaS03-containing FGD was found to inhibit acid leaching from both fresh and aged coal refuse in large scale columns under simulated field conditions. During 39 weeks of leaching, the reduction of leachate acidity and Fe concentration and the increase ofleachate pH were significant (p <0.05) for the 22% FGD treatment with a linear response to increasing FGD rates (0%, 5.5%, 11%, and 22%). I conclude that CaS03 and CaS03-containing FGD have the ability to inhibit acid production in coal refuse and the inhibitory effect shown in this experiment is likely to occur under field conditions. Thus, the research results present a potential new method for mitigation of acid production in coal refuse and another beneficial utilization of FGD by-products.

    Full Text Available Busca-se por meio deste artigo discutir as relações de gênero no Ensino Superior, mas especificamente entre discentes e docentes. Para tanto, foi realizada uma pesquisa com docentes de uma instituição superior privada localizada na Região Metropolitana da Grande Vitória-ES, sendo a estes aplicados questionários fechados. Objetiva-se, a partir das colaborações teóricas de Bourdieu e Beauvoir, discutir a percepção dos docentes dos sexos masculinos e femininos quanto às relações entre professor-aluno.  Identificou-se que mesmo que o Ensino Superior, campo investigado pela pesquisa, caracterize-se como “menos masculino”, a coleta de campo evidenciou que existem momentos em que a desigualdade entre gênero torna-se mais evidente.   This article seeks to discuss gender relations in Higher Education, but specifically between students and teachers. For this, a survey was conducted with teachers from a private higher education institution located in the Greater Vitória Metropolitan Region-ES, to whom were given closed questionnaires.The objective was to discuss the perceptions of male and female teachers regarding professor-student relationships, from the point of view of the theoretical collaborations of Bourdieu and Beauvoir. It was seen that even though Higher Education, the field investigated by this research, is characterized as "less masculine,” the field collection found evidence that there are moments in which the inequality between genders becomes more evident.

    Recent research on United States levels and trends in income inequality vary substantially in how they measure income. Piketty and Saez (2003) examine market income of tax units based on IRS tax return data, DeNavas-Walt, Proctor, and Smith (2012) and most CPS-based research uses pre-tax, post-transfer cash income of households, while the CBO (2012) uses both data sets and focuses on household size-adjusted comprehensive income of persons, including taxable realized capital gains.

    Full Text Available Resumen: El artículo sitúa la vejez en la sociedad contemporánea, etapa de la vida traspasada por múltiples significados asignados por el biocapitalismo (NEGRI, 2014, que la estigmatizó con denominaciones despectivas. Entre las dominantes encontramos aquellas que representan al "viejo/a" como un "problema" "una carga insoportable" para las familias que, cada vez con mayor frecuencia, delegan su cuidado a instituciones especializadas, encontrándose muchas veces el anciano/a en un estado de abandono y desamparo. Desde esta perspectiva afirmamos que de todas las franjas etarias es sin duda la más desfavorecida, situación que se agrava al considerarse la perspectiva de género. La sociedad actual valoriza la juventud y la fuerza de trabajo socialmente productiva y a pesar de los avances insoslayables en este terreno, todavía sigue organizándose bajo una perspectiva patriarcal. Cabe preguntarnos ¿Qué pasa con las mujeres ancianas? ¿Son acaso doblemente desfavorecidas? ¿Pueden ser identificarse como doblemente dominadas? ¿Cuáles son las consecuencias subjetivas de su posición social? ¿Cómo esto se expresa en su corporeidad? El presente trabajo pretende tratar estas cuestiones y proponer el dispositivo Historia Vital del Trabajo (HVT como una herramienta terapéutica que busca contribuir con la elaboración de un proyecto de vida en el que se recupere, en la subjetividad y en el cuerpo de la mujer anciana, una capacidad de trabajo creativo susceptible de ser valorizado socialmente. A tal efecto se reflexionará sobre la obra "la vejez" de Beauvoir (1970 en tanto se considera que la autora aborda la problemática con valor no solo teórico sino también testimonial.

    Seven acrylic bone cements were evaluated: Cemex Rx (Tecres S.p.a., Italy), Cemex Isoplastic (Tecres S.p.a., Italy), Zimmer Low Viscosity Cement (L.V.C., Zimmer, IN, USA), Zimmer bone cement - dough type (Zimmer, IN, USA), CMW (DePuy International Ltd., UK), Cerim LT (Cremascoli S.r.l., Italy), and Palacos (Merck, Wehreim, Germany). The cements after polymerization were put in contact in vitro with platelet-rich plasma. Plasma in contact only with siliconated glass was used as the negative control. After contact, platelet number, beta-thromboglobulin (beta-TG), and transforming growth factor-beta1 (TGF-beta1) were determined. The Wilcoxon signed rank test showed Palacos R and L.V.C. induced a significant decrease of platelet number compared with the negative control. All cements determined a significant increase in beta-TG. CMW 3, Palacos, L.V.C., and Zimmer dough type determined a significant increase in TGF-beta1 compared with the negative control.

  14. Aproximações de Roger Bastide, Jean Paul Sartre e Simone de Beauvior com o cinema de Orlando Senna: influências da Filosofia e Sociologia nas telas

    Full Text Available Em autobiografia, Orlando Senna descreve a importância dos trabalhos de Bastide, Beauvoir e Sartre para sua produção cinematográfica. Essa pesquisa buscou mapear os diálogos que o cineasta faz com o pensamento filosófico existencialista e as aproximações com a sociologia de Bastide no filme Iracema: uma transa amazônica, produzido em conjunto com o produtor Jorge Bodanzky. Dessa forma, foi possível perceber que as leituras construídas no roteiro fílmico e nas ações dos atores indicam a presença da filosofia existencialista atrelada ao pensamento feminista e marxista, o que revela a preocupação em caracterizar o pensamento filosófico dos autores no filme. Por outro lado, a preocupação em retratar a mulher negra e a aproximação de Bastide e Senna com o candomblé reitera a aproximação temática na produção. Assim, verifica-se a posição do cineasta como intelectual de esquerda, produtor de cultura que embasa seu trabalho na Filosofia existencialista.

    The male of Eustala vellardi Mello-Leitão, 1924 and the female of E. delasmata Bryant, 1945 are described for the first time and new distribution records are provided. The types of E. tridentata (C.L. Koch, 1838), E. tristis (Blackwall, 1862), E. essequibensis (Hingston, 1932), E. uncicurva Franganillo, 1936, E. nigerrima Mello-Leitão, 1940, and E. albicans (Caporiacco, 1954), are apparently lost, and those names are therefore, considered nomina dubia. Eustala andina Chamberlin, 1916, which is based on an immature female is also considered a nomen dubium.

    This is an answer to the Letter to the Editor regarding our previously published article « Saccular measurements in routine MRI can predict hydrops in Menière's disease ». We thank the authors for their interest in our article and their insightful comments. We would like to emphasise that our article was a preliminary study and to our knowledge the first published series establishing a correlation between measurements of saccular morphology in T2-weighed 3D CISS images and clinical definite Menière's disease. Therefore, we agree with the authors of the Letter that verifying reproducibility is paramount for the technique to be widely used. Further studies should be conducted to investigate the risk of artefacts reducing the reliability of saccular width measurements and to confirm the clinical implications. We recommend the use of saccular height measurements which have higher reliability. Also, the goal of the study was to present a possible radiological alternative to the more established methods of endolymphatic hydrops visualisation. If accessible, we agree that the latter techniques should be preferred, but we find that they are unfortunately too often unavailable in routine clinical practice to ENT physicians.

    This paper presents the findings from an evaluation of a creative musical project led by Scottish Opera. The project included people with dementia and their carers in the development, writing, design and performance of a musical production about their experiences of love. The project involved professional singers, artists and choreographers from the opera company. Activities involved practice sessions and performances. People with dementia and their carers reflected on positive outcomes from the project including improved confidence; being part of a group; improved physical strength and people seeing them in a new way. Within the evaluation framework they also reported on how the project had been run and gave ideas for future development. Key elements in the success of this project were the involvement of professionals, the kudos of working with a national organisation and the performances that, while daunting, provided unique and rewarding experiences. © The Author(s) 2013.

  20. The Susan G. Komen for the Cure® Tissue Bank at the IU Simon Cancer Center: A Unique Resource for Defining the “Molecular Histology” of the Breast

    “Molecular histology” of the breast may be conceptualized as encompassing the normative ranges of histological structure and marker expression in normal breast tissues in relation to a woman’s age and life experiences. Studies of molecular histology can aid our understanding of early events in breast carcinogenesis and provide data for comparison with diseased breast tissues. Until recently, lack of epidemiologically annotated, optimally prepared normal breast tissues obtained from healthy women presented a barrier to breast cancer research. The Komen Tissue Bank at Indiana University is a unique biorepository that was developed to overcome this limitation. The Bank enrolls healthy donors who provide questionnaire data, blood, and up to four breast biopsies, which are prepared as both formalin fixed paraffin embedded and frozen tissues. The resource is accessible to researchers worldwide through a proposal submission, review, and approval process. As of November 2010, the Bank had collected specimens and information from 1,174 donors. In this review, we discuss the importance of studying normal breast tissues, assess the strengths and limitations of studying normal tissues obtained from different sources, and summarize the features of the Komen Tissue Bank. As research projects are completed, results will be posted on the Bank’s website. PMID:22345117
