Universal regularization prescription for Lovelock AdS gravity

International Nuclear Information System (INIS)

Kofinas, Georgios; Olea, Rodrigo

2007-01-01

A definite form for the boundary term that produces the finiteness of both the conserved quantities and Euclidean action for any Lovelock gravity with AdS asymptotics is presented. This prescription merely tells even from odd bulk dimensions, regardless the particular theory considered, what is valid even for Einstein-Hilbert and Einstein-Gauss-Bonnet AdS gravity. The boundary term is a given polynomial of the boundary extrinsic and intrinsic curvatures (also referred to as Kounterterms series). Only the coupling constant of the boundary term changes accordingly, such that it always preserves a well-posed variational principle for boundary conditions suitable for asymptotically AdS spaces. The background-independent conserved charges associated to asymptotic symmetries are found. In odd bulk dimensions, this regularization produces a generalized formula for the vacuum energy in Lovelock AdS gravity. The standard entropy for asymptotically AdS black holes is recovered directly from the regularization of the Euclidean action, and not only from the first law of thermodynamics associated to the conserved quantities

Lorentzian AdS, Wormholes and Holography

CERN Document Server

Arias, Raul E; Silva, Guillermo A

2011-01-01

We investigate the structure of two point functions for the QFT dual to an asymptotically Lorentzian AdS-wormhole. The bulk geometry is a solution of 5-dimensional second order Einstein Gauss Bonnet gravity and causally connects two asymptotically AdS space times. We revisit the GKPW prescription for computing two-point correlation functions for dual QFT operators O in Lorentzian signature and we propose to express the bulk fields in terms of the independent boundary values phi_0^\\pm at each of the two asymptotic AdS regions, along the way we exhibit how the ambiguity of normalizable modes in the bulk, related to initial and final states, show up in the computations. The independent boundary values are interpreted as sources for dual operators O^\\pm and we argue that, apart from the possibility of entanglement, there exists a coupling between the degrees of freedom leaving at each boundary. The AdS_(1+1) geometry is also discussed in view of its similar boundary structure. Based on the analysis, we propose a ...

Cosmopolitan political science.

Science.gov (United States)

Grande, Edgar

2006-03-01

Until recently, the term cosmopolitism could rarely be found in modern political science literature. It was only in the 1990s that the term was rediscovered by political scientists in the critical discourse on globalization. In this article, I will explore the full potential of cosmopolitism as an analytical concept for empirical political science. I will argue that the concept of cosmopolitism should not be restricted to the analysis of global politics. Indeed, cosmopolitism has much more to offer for political scientists. Properly understood, it enables--and necessitates--a re-invention of political science in the age of globalization, comparable to the behavioural revolution in political science in the 1950s. Such a paradigmatic shift should be based on a twofold transformation of existing disciplinary boundaries: A removal of the boundary between national (and comparative) and international politics on the one hand; and a re-definition of the boundaries between empirical and normative approaches on the other. As a result, cosmopolitism may serve as a new, critical theory of politics based on the integration of hitherto separated fields and sub-fields.

Holography beyond conformal invariance and AdS isometry?

CERN Document Server

Barvinsky, A.O.

2015-01-01

We suggest that the principle of holographic duality can be extended beyond conformal invariance and AdS isometry. Such an extension is based on a special relation between functional determinants of the operators acting in the bulk and on its boundary, provided that the boundary operator represents the inverse propagators of the theory induced on the boundary by the Dirichlet boundary value problem from the bulk spacetime. This relation holds for operators of general spin-tensor structure on generic manifolds with boundaries irrespective of their background geometry and conformal invariance, and it apparently underlies numerous $O(N^0)$ tests of AdS/CFT correspondence, based on direct calculation of the bulk and boundary partition functions, Casimir energies and conformal anomalies. The generalized holographic duality is discussed within the concept of the "double-trace" deformation of the boundary theory, which is responsible in the case of large $N$ CFT coupled to the tower of higher spin gauge fields for t...

Holographic description of AdS2 black holes

International Nuclear Information System (INIS)

Castro, Alejandra; Larsen, Finn; Grumiller, Daniel; McNees, Robert

2008-01-01

We develop the holographic renormalization of AdS 2 gravity systematically. We find that a bulk Maxwell term necessitates a boundary mass term for the gauge field and verify that this unusual term is invariant under gauge transformations that preserve the boundary conditions. We determine the energy-momentum tensor and the central charge, recovering recent results by Hartman and Strominger. We show that our expressions are consistent with dimensional reduction of the AdS 3 energy-momentum tensor and the Brown-Henneaux central charge. As an application of our results we interpret the entropy of AdS 2 black holes as the ground state entropy of a dual CFT.

Polarised Black Holes in AdS

Costa, Miguel S.; Oliveira, Miguel; Penedones, João; Santos, Jorge E.

2016-05-03

We consider solutions in Einstein-Maxwell theory with a negative cosmological constant that asymptote to global $AdS_{4}$ with conformal boundary $S^{2}\\times\\mathbb{R}_{t}$. At the sphere at infinity we turn on a space-dependent electrostatic potential, which does not destroy the asymptotic $AdS$ behaviour. For simplicity we focus on the case of a dipolar electrostatic potential. We find two new geometries: (i) an $AdS$ soliton that includes the full backreaction of the electric field on the $AdS$ geometry; (ii) a polarised neutral black hole that is deformed by the electric field, accumulating opposite charges in each hemisphere. For both geometries we study boundary data such as the charge density and the stress tensor. For the black hole we also study the horizon charge density and area, and further verify a Smarr formula. Then we consider this system at finite temperature and compute the Gibbs free energy for both $AdS$ soliton and black hole phases. The corresponding phase diagram generalizes the Hawkin...

Vacuum currents in braneworlds on AdS bulk with compact dimensions

Science.gov (United States)

Bellucci, S.; Saharian, A. A.; Vardanyan, V.

2015-11-01

The two-point function and the vacuum expectation value (VEV) of the current density are investigated for a massive charged scalar field with arbitrary curvature coupling in the geometry of a brane on the background of AdS spacetime with partial toroidal compactification. The presence of a gauge field flux, enclosed by compact dimensions, is assumed. On the brane the field obeys Robin boundary condition and along compact dimensions periodicity conditions with general phases are imposed. There is a range in the space of the values for the coefficient in the boundary condition where the Poincaré vacuum is unstable. This range depends on the location of the brane and is different for the regions between the brane and AdS boundary and between the brane and the horizon. In models with compact dimensions the stability condition is less restrictive than that for the AdS bulk with trivial topology. The vacuum charge density and the components of the current along non-compact dimensions vanish. The VEV of the current density along compact dimensions is a periodic function of the gauge field flux with the period equal to the flux quantum. It is decomposed into the boundary-free and brane-induced contributions. The asymptotic behavior of the latter is investigated near the brane, near the AdS boundary and near the horizon. It is shown that, in contrast to the VEVs of the field squared an denergy-momentum tensor, the current density is finite on the brane and vanishes for the special case of Dirichlet boundary condition. Both the boundary-free and brane-induced contributions vanish on the AdS boundary. The brane-induced contribution vanishes on the horizon and for points near the horizon the current is dominated by the boundary-free part. In the near-horizon limit, the latter is connected to the corresponding quantity for a massless field in the Minkowski bulk by a simple conformal relation. Depending on the value of the Robin coefficient, the presence of the brane can either

Stability of warped AdS3 vacua of topologically massive gravity

International Nuclear Information System (INIS)

Anninos, Dionysios; Esole, Mboyo; Guica, Monica

2009-01-01

AdS 3 vacua of topologically massive gravity (TMG) have been shown to be perturbatively unstable for all values of the coupling constant except the chiral point μl = 1. We study the possibility that the warped vacua of TMG, which exist for all values of μ, are stable under linearized perturbations. In this paper, we show that spacelike warped AdS 3 vacua with Compere-Detournay boundary conditions are indeed stable in the range μl>3. This is precisely the range in which black hole solutions arise as discrete identifications of the warped AdS 3 vacuum. The situation somewhat resembles chiral gravity: although negative energy modes do exist, they are all excluded by the boundary conditions, and the perturbative spectrum solely consists of boundary (pure large gauge) gravitons.

Complexity of the AdS soliton

Science.gov (United States)

Reynolds, Alan P.; Ross, Simon F.

2018-05-01

We consider the holographic complexity conjectures in the context of the AdS soliton, which is the holographic dual of the ground state of a field theory on a torus with antiperiodic boundary conditions for fermions on one cycle. The complexity is a non-trivial function of the size of the circle with antiperiodic boundary conditions, which sets an IR scale in the dual geometry. We find qualitative differences between the calculations of complexity from spatial volume and action (CV and CA). In the CV calculation, the complexity for antiperiodic boundary conditions is smaller than for periodic, and decreases monotonically with increasing IR scale. In the CA calculation, the complexity for antiperiodic boundary conditions is larger than for periodic, and initially increases with increasing IR scale, eventually decreasing to zero as the IR scale becomes of order the UV cutoff. We compare these results to a simple calculation for free fermions on a lattice, where we find the complexity for antiperiodic boundary conditions is larger than for periodic.

Supergravity one-loop corrections on AdS7 and AdS3, higher spins and AdS/CFT

Directory of Open Access Journals (Sweden)

Matteo Beccaria

2015-03-01

Full Text Available As was shown earlier, the one-loop correction in 10d supergravity on AdS5×S5 corresponds to the contributions to the vacuum energy and 4d boundary conformal anomaly which are minus the values for one N=4 Maxwell supermultiplet, thus reproducing the subleading term in the N2−1 coefficient in the dual SU(N SYM theory. We perform similar one-loop computations in 11d supergravity on AdS7×S4 and 10d supergravity on AdS3×S3×T4. In the AdS7 case we find that the corrections to the 6d conformal anomaly a-coefficient and the vacuum energy are again minus the ones for one (2,0 tensor multiplet, suggesting that the total a-anomaly coefficient for the dual (2,0 theory is 4N3−9/4N−7/4 and thus vanishes for N=1. In the AdS3 case the one-loop correction to the vacuum energy or 2d central charge turns out to be equal to that of one free (4,4 scalar multiplet, i.e. is c=+6. This reproduces the subleading term in the central charge c=6(Q1Q5+1 of the dual 2d CFT describing decoupling limit of D5–D1 system. We also present the expressions for the 6d a-anomaly coefficient and vacuum energy contributions of general-symmetry higher spin field in AdS7 and consider their application to tests of vectorial AdS/CFT with the boundary conformal 6d theory represented by free scalars, spinors or rank-2 antisymmetric tensors.

Welcoming Diversity? Symbolic Boundaries and the Politics of Normativity in Kansas City's LGBTQ Communities.

Science.gov (United States)

Vogler, Stefan

2016-01-01

Using document analysis and ethnographic field work, this article examines the debate within the LGBTQ community of Kansas City over the decision to hold its Pride festival in the Power and Light District (P&L), a renewed downtown area with a controversial dress code. Despite the developers' and city's goals of creating a cosmopolitan urban space that welcomed diverse populations, the P&L acquired a reputation as an anti-Black, anti-queer space due to its dress code and redevelopment history. I argue that the debate surrounding this controversy reveals limits to notions of diversity and diverging approaches to sexual politics within the LGBTQ community that are normally obscured by political actors within the movement but that work to create symbolic boundaries that exclude "non-respectable" members of the LGBTQ population. Recovering queer perspectives allows us to imagine a more capacious definition of diversity and inclusion, both within the LGBTQ movement and in urban space.

Phases of planar AdS black holes with axionic charge

International Nuclear Information System (INIS)

Caldarelli, Marco M.; Christodoulou, Ariana; Papadimitriou, Ioannis; Skenderis, Kostas

2017-01-01

Planar AdS black holes with axionic charge have finite DC conductivity due to momentum relaxation. We obtain a new family of exact asymptotically AdS 4 black branes with scalar hair, carrying magnetic and axion charge, and we study the thermodynamics and dynamic stability of these, as well as of a number of previously known electric and dyonic solutions with axion charge and scalar hair. The scalar hair for all solutions satisfy mixed boundary conditions, which lead to modified holographic Ward identities, conserved charges and free energy, relative to those following from the more standard Dirichlet boundary conditions. We show that properly accounting for the scalar boundary conditions leads to well defined first law and other thermodynamic relations. Finally, we compute the holographic quantum effective potential for the dual scalar operator and show that dynamical stability of the hairy black branes is equivalent to positivity of the energy density.

Hawking radiation and quantum anomaly in AdS2/CFT1 correspondence

International Nuclear Information System (INIS)

Morita, Takeshi

2009-01-01

In order to understand a boundary description of Hawking radiation in the AdS/CFT correspondence, we investigate the trace anomaly method in AdS 2 space. In this method, Hawking radiation is derived from the trace anomaly of the energy-momentum tensor in the bulk. We find a correspondence between the energy-momentum tensor and a composite operator in CFT 1 and understand the anomalous properties of the energy-momentum tensor in terms of this composite operator. By using this correspondence, we reproduce Hawking radiation from the boundary description. In addition, we find a correspondence between higher-spin currents in the bulk and composite operators in the boundary.

Entanglement entropy and duality in AdS4

Directory of Open Access Journals (Sweden)

Ioannis Bakas

2015-07-01

Full Text Available Small variations of the entanglement entropy δS and the expectation value of the modular Hamiltonian δE are computed holographically for circular entangling curves in the boundary of AdS4, using gravitational perturbations with general boundary conditions in spherical coordinates. Agreement with the first law of thermodynamics, δS=δE, requires that the line element of the entangling curve remains constant. In this context, we also find a manifestation of electric–magnetic duality for the entanglement entropy and the corresponding modular Hamiltonian, following from the holographic energy–momentum/Cotton tensor duality.

Boundary actions for three-dimensional quantum gravity in the discretized formalism of Ponzano-Regge are studied with a view towards understanding the boundary degrees of freedom. These degrees of freedom postulated in the holography hypothesis are supposed to be characteristic of quantum gravity theories. In particular it is expected that some of these degrees of freedom reside on black hole horizons. This paper is a study of these ideas in the context of a theory of quantum gravity that req...

Smooth causal patches for AdS black holes

Science.gov (United States)

Raju, Suvrat

2017-06-01

We review the paradox of low energy excitations of a black hole in anti-de Sitter space (AdS). An appropriately chosen unitary operator in the boundary theory can create a locally strong excitation near the black hole horizon, whose global energy is small as a result of the gravitational redshift. The paradox is that this seems to violate a general rule of statistical mechanics, which states that an operator with energy parametrically smaller than k T cannot create a significant excitation in a thermal system. When we carefully examine the position dependence of the boundary unitary operator that produces the excitation and the bulk observable necessary to detect the anomalously large effect, we find that they do not both fit in a single causal patch. This follows from a remarkable property of position-space AdS correlators that we establish explicitly and resolves the paradox in a generic state of the system, since no combination of observers can both create the excitation and observe its effect. As a special case of our analysis, we show how this resolves the "Born rule" paradox of Marolf and Polchinski [J. High Energy Phys. 01 (2016) 008, 10.1007/JHEP01(2016)008] and we verify our solution using an independent calculation. We then consider boundary states that are finely tuned to display a spontaneous excitation outside the causal patch of the infalling observer, and we propose a version of causal patch complementarity in AdS/CFT that resolves the paradox for such states as well.

Open strings on AdS2 branes

International Nuclear Information System (INIS)

Lee, Peter; Ooguri, Hirosi.; Park, Jongwon; Tannenhauser, Jonathan

2001-01-01

We study the spectrum of open strings on AdS 2 branes in AdS 3 in an NS-NS background, using the SL(2,R) WZW model. When the brane carries no fundamental string charge, the open string spectrum is the holomorphic square root of the spectrum of closed strings in AdS 3 . It contains short and long strings, and is invariant under spectral flow. When the brane carries fundamental string charge, the open string spectrum again contains short and long strings in all winding sectors. However, branes with fundamental string charge break half the spectral flow symmetry. This has different implications for short and long strings. As the fundamental string charge increases, the brane approaches the boundary of AdS 3 . In this limit, the induced electric field on the worldvolume reaches its critical value, producing noncommutative open string theory on AdS 2

Comparison between various notions of conserved charges in asymptotically AdS spacetimes

Hollands, Stefan; Ishibashi, Akihiro; Marolf, Donald

2005-01-01

We derive Hamiltonian generators of asymptotic symmetries for general relativity with asymptotic AdS boundary conditions using the 'covariant phase space' method of Wald et al. We then compare our results with other definitions that have been proposed in the literature. We find that our definition agrees with that proposed by Ashtekar et al, with the spinor definition, and with the background-dependent definition of Henneaux and Teitelboim. Our definition disagrees with that obtained from the 'counterterm subtraction method', but the difference is found to consist only of a 'constant offset' that is determined entirely in terms of the boundary metric. We finally discuss and justify our boundary conditions by a linear perturbation analysis, and we comment on generalizations of our boundary conditions, as well as inclusion of matter fields

Pushing at the boundaries of the body: Cultural politics and cross-gender dance in East Java

Directory of Open Access Journals (Sweden)

Christina Sunardi

2009-12-01

Full Text Available Cross-gender dance in East Java has captivated me as a strategy that performers use to negotiate multiple ideas about manhood and womanhood as well as tensions between official ideologies and social realities, expectations about performers’ onstage personas and offstage lives, and competing aesthetic sensibilities. Drawing on ethnographic fieldwork in the regency of Malang and analysis of performers’ verbal discourse, I address issues of the body, perception, agency, and senses of self, foregrounding performers’ insights into their practices’ meanings, the cultural impact they have as artists, and reasons behind multiple perceptions of gender. To examine relationships between larger cultural forces and performers’ views, I use generation as an analytical framework. I consider performers in three generations – the 1940s-1960s, the 1970s-1990s, and the 1990s to the present. That these generations correlate closely to three political periods in Indonesian history – Old Order (1945-1965/6, New Order (1966-1998, and Reformation Era (1998-present – has led me to make three related arguments. First, the political and cultural climate has affected the discourse through which musicians and dancers expressed their perceptions about the performance of gender. Second, performers have rearticulated larger cultural and political discourses in their own ways, thereby asserting their own senses of gender. Third, performers have affected the political and cultural climate by pushing at the boundaries of maleness and femaleness onstage and in their daily lives, making on- and offstage spaces fluid and complementary sites of cultural and ideological production.

Central charge for AdS2 quantum gravity

International Nuclear Information System (INIS)

Hartman, Thomas; Strominger, Andrew

2009-01-01

Two-dimensional Maxwell-dilaton quantum gravity on AdS 2 with radius l and a constant electric field E is studied. In conformal gauge, this is equivalent to a CFT on a strip. In order to maintain consistent boundary conditions, the usual conformal diffeomorphisms must be accompanied by a certain U(1) gauge transformation. The resulting conformal transformations are generated by a twisted stress tensor, which has a central charge c = 3kE 2 l 4 /4 where k is the level of the U(1) current. This is an AdS 2 analog of the Brown-Henneaux formula c = 3l/2G for the central charge of quantum gravity on AdS 3 .

State Operator Correspondence and Entanglement in AdS2/CFT1

Directory of Open Access Journals (Sweden)

Ashoke Sen

2011-07-01

Full Text Available Since Euclidean global AdS2 space represented as a strip has two boundaries, the state-operator correspondence in the dual CFT1 reduces to the standard map from the operators acting on a single copy of the Hilbert space to states in the tensor product of two copies of the Hilbert space. Using this picture we argue that the corresponding states in the dual string theory living on AdS2 × K are described by the twisted version of the Hartle–Hawking states, the twists being generated by a large unitary group of symmetries that this string theory must possess. This formalism makes natural the dual interpretation of the black hole entropy—as the logarithm of the degeneracy of ground states of the quantum mechanics describing the low energy dynamics of the black hole, and also as an entanglement entropy between the two copies of the same quantum theory living on the two boundaries of global AdS2 separated by the event horizon.

Penedones, Joao

2017-01-01

We introduce the AdS/CFT correspondence as a natural extension of QFT in a fixed AdS background. We start by reviewing some general concepts of CFT, including the embedding space formalism. We then consider QFT in a fixed AdS background and show that one can define boundary operators that enjoy very similar properties as in a CFT, except for the lack of a stress tensor. Including a dynamical metric in AdS generates a boundary stress tensor and completes the CFT axioms. We also discuss some applications of the bulk geometric intuition to strongly coupled QFT. Finally, we end with a review of the main properties of Mellin amplitudes for CFT correlation functions and their uses in the context of AdS/CFT.

The Ottoman Siege and Assault of Constantinople in 1422 AD: Its Military and Political Aspect

Directory of Open Access Journals (Sweden)

Tatiana V. Kushch

2017-11-01

Full Text Available This paper addresses the military and political aspect of the Turkish siege of Constantinople in 1422 AD, when the Ottomans gained valuable experience to use it later, in the final battle of 1453. The research is based on the analysis of fifteenth-century Byzantine historical and rhetorical works. The author of this paper has reconstructed the course of the siege and the main stages of preparation to the decisive assault, has analysed the enemy’s military plans, the alignment of forces and tactical ploys of siege warfare, the specificities of Ottoman weaponry, and the sides’ actions during the assault. Attention has been paid to the Byzantines’ behaviour in the period of military conflict and the emperors’ political actions for the conflict resolution. The history of the siege and assault of the Byzantine capital in 1422 has been placed into the political context of the period in question, and has been uncovered as a stage in the development of the Byzantine-Ottoman relations in the late fourteenth and early fifteenth century. The paper concludes that the Ottomans’ rout resulted from a series of circumstances: the perfection of the fortification system of Constantinople, total mobilization of the metropolitan population, the lack of maritime blockade, and the rebel in the rear of the Ottomans starting not without a help from the Byzantines, all of this allowed the city to withstand. The siege was relieved; however, the situation in foreign policy was still difficult for Byzantium, thus making the emperor to search for peace with the sultan.

Evaporation of large black holes in AdS

International Nuclear Information System (INIS)

Rocha, Jorge V

2010-01-01

The AdS/CFT correspondence offers a new perspective on the long-standing black hole information paradox. However, to be able to use the available gauge/gravity machinery one is forced to consider so-called 'large' black holes in AdS, and these objects are thermodynamically stable - they do not evaporate. We describe a simple toy model that allows large AdS black holes to decay, by coupling the emitted radiation to an external scalar field propagating in an auxiliary space. This effectively changes the properties of the boundary of AdS, making it partly absorbing. We demonstrate that the evaporation process never ceases by explicitly presenting (a) the transmission coefficient for a wave scattering from the bulk into auxiliary space and (b) the greybody factor for a black 3-brane in an AdS background. Therefore, the model provides an interesting framework to address the information paradox using AdS/CFT techniques.

We study the realization of inflation within the AdS/CFT correspondence. We assume the existence of a string landscape containing at least one stable AdS vacuum and a (nearby) metastable de Sitter state.

D-brane potentials from multi-trace deformations in AdS/CFT

It is known that certain AdS boundary conditions allow smooth initial data to evolve into a big crunch. To study this type of cosmological singularity, one can use the dual quantum field theory, where the non-standard boundary conditions are reflected by the presence of a multi-trace potential unbounded below. For specific AdS 4 and AdS 5 models, we provide a D-brane (or M-brane) interpretation of the unbounded potential. Using probe brane computations, we show that the AdS boundary conditions of interest cause spherical branes to be pushed to the boundary of AdS in finite time, and that the corresponding potential agrees with the multi-trace deformation of the dual field theory. Systems with expanding spherical D3-branes are related to big crunch supergravity solutions by a phenomenon similar to geometric transition.

Exploring the bulk in AdS /CFT : A covariant approach

Science.gov (United States)

Engelhardt, Netta

2017-03-01

I propose a general, covariant way of defining when one region is "deeper in the bulk" than another. This definition is formulated outside of an event horizon (or in the absence thereof) in generic geometries; it may be applied to both points and surfaces, and it may be used to compare the depth of bulk points or surfaces relative to a particular boundary subregion or relative to the entire boundary. Using the recently proposed "light-cone cut" formalism, the comparative depth between two bulk points can be determined from the singularity structure of Lorentzian correlators in the dual field theory. I prove that, by this definition, causal wedges of progressively larger regions probe monotonically deeper in the bulk. The definition furthermore matches expectations in pure AdS and in static AdS black holes with isotropic spatial slices, where a well-defined holographic coordinate exists. In terms of holographic renormalization group flow, this new definition of bulk depth makes contact with coarse graining over both large distances and long time scales.

Trade liberalization and political separatism go hand in hand. In a world of trade restrictions, large countries enjoy economic benefits because political boundaries determine the size of the market. In a world of free trade and global markets even relatively small cultural, linguistic or ethnic groups can benefit from forming small and homogeneous political jurisdictions that trade peacefully and are economically integrated with others.

A trauma-like model of political extremism: psycho-political fault lines in Israel.

Laor, Nathaniel; Yanay-Shani, Alma; Wolmer, Leo; Khoury, Oula

2010-10-01

This study examines a trauma-like model of potentially violent political extremism among Jewish Israelis. We study the psychosocial characteristics of political extremists that may lie at the root of sociopolitical instability and assess personal (gender, stressful life events, Holocaust family background, and political activism) and psychological parameters (self- and political transcendence, perceived political threats, in/out-group identification ratio) that may predict readiness to engage in destructive political behavior. We examine the ideological zeal of various political groups, the relationship between the latter and perceived political threats, and the predictors of extreme political activism. Results showed that the extreme political poles displayed high level of ideological and morbid transcendence. Right extremists displayed higher perceived threats to physical existence and national identity. Left extremists scored highest on perceived moral integrity threat. Higher perceived threats to national identity and moral integrity, risk, and self-transcendence statistically explain morbid transcendence. When fear conjures up extremely skewed sociopolitical identifications across political boundaries, morbid transcendence may manifest itself in destructive political activity. © 2010 Association for Research in Nervous and Mental Disease.

Finite action for Chern-Simons Ads gravity

Energy Technology Data Exchange (ETDEWEB)

Mora, P.; Olea, R.; Troncoso, R.; Zanelli, J. E-mail: jz@cecs.cl

2004-06-01

A finite principle for Chern-Simons AdS gravity is presented. The construction is carried out in detail first in five dimensions, where the bulk action is given by a particular combination of the Einstein-Hilbert action with negative cosmological constant and a Gauss-Bonnet term; and is then generalized for arbitrary odd dimensions. The boundary term needed to render the action finite is singled out demanding the action to attain an extremum for an appropriate set of boundary conditions. The boundary term is a local function of the fields at the boundary and is sufficient to render the action finite for asymptotically AdS solutions, without requiring background fields. It is shown that the Euclidean continuation of the action correctly describes black hole thermodynamics in the canonical ensemble. Additionally, background independent conserved charges associated with the asymptotic symmetries can be written as surface integrals by direct application of Noether's theorem. (author)

Political boundary conditions for a reliable energy supply

International Nuclear Information System (INIS)

Majewski, O.

1994-01-01

The further course of energy policy in Germany is completely uncertain, especially in the light of the elections to be held in Germany in 1994. At the very last minute, the attempt at finding a long-term energy consensus failed although the positions held by the participants from politics, industry, and other groupings had already come much closer. Against the backdrop of a profound recession and a structural crisis of industry, on the one hand, and increasingly tougher international competition, on the other hand, the parameters of energy policy contribute greatly to the success or failure of future economic development. One of the objectives of the consensus talks had been to maintain an energy mix so as to spread more widely the economic, technical, political, and ecological risks that would be encountered. In particular, a permanent perspective was to be developed for the peaceful uses of nuclear power, on the one hand, by ensuring the politically undisturbed operation of the nuclear power plants currently in operation and, on the other hand, by creating a concrete, sustainable option for the development and operation of an advanced generation of nuclear reactors.

AdS5 black holes with fermionic hair

Burrington, Benjamin A.; Liu, James T.; Sabra, W. A.

2005-01-01

The study of new Bogomol'nyi-Prasad-Sommerfield (BPS) objects in AdS 5 has led to a deeper understanding of AdS/CFT. To help complete this picture, and to fully explore the consequences of the supersymmetry algebra, it is also important to obtain new solutions with bulk fermions turned on. In this paper we construct superpartners of the 1/2 BPS black hole in AdS 5 using a natural set of fermion zero modes. We demonstrate that these superpartners, carrying fermionic hair, have conserved charges differing from the original bosonic counterpart. To do so, we find the R-charge and dipole moment of the new system, as well as the mass and angular momentum, defined through the boundary stress tensor. The complete set of superpartners fits nicely into a chiral representation of AdS 5 supersymmetry, and the spinning solutions have the expected gyromagnetic ratio, g=1

Influence of the added mass effect and boundary conditions on the dynamic response of submerged and confined structures

Valentín, D; Presas, A; Egusquiza, E; Valero, C

2014-01-01

The dynamic response of submerged and confined disk-like structures is of interest in the flied of hydraulic machinery, especially in hydraulic turbine runners. This response is difficult to be estimated with accuracy due to the strong influence of the boundary conditions. Small radial gaps as well as short axial distances to rigid surfaces greatly modify the dynamic response because the fact of the added mass and damping effects. Moreover, the effect of the shaft coupling is also important for certain mode-shapes of the structure. In the present study, the influence of the added mass effect and boundary conditions on the dynamic behavior of a submerged disk attached to a shaft is evaluated through experimental tests and structural- acoustic coupling numerical simulations. For the experimentation, a test rig has been developed. It consists of a confined disk attached to a shaft inside a cylindrical container full of water. The disk can be fixed at different axial positions along the shaft. Piezoelectric patches are used to excite the disk and the response is measured with submersible accelerometers. For each configuration tested, the natural frequencies of the disk and the shaft are studied. Numerical results have been compared with experimental results

Warped AdS3 black holes

Anninos, Dionysios; Li Wei; Padi, Megha; Song Wei; Strominger, Andrew

2009-01-01

Three dimensional topologically massive gravity (TMG) with a negative cosmological constant -l -2 and positive Newton constant G admits an AdS 3 vacuum solution for any value of the graviton mass μ. These are all known to be perturbatively unstable except at the recently explored chiral point μl = 1. However we show herein that for every value of μl ≠ 3 there are two other (potentially stable) vacuum solutions given by SL(2,R) x U(1)-invariant warped AdS 3 geometries, with a timelike or spacelike U(1) isometry. Critical behavior occurs at μl = 3, where the warping transitions from a stretching to a squashing, and there are a pair of warped solutions with a null U(1) isometry. For μl > 3, there are known warped black hole solutions which are asymptotic to warped AdS 3 . We show that these black holes are discrete quotients of warped AdS 3 just as BTZ black holes are discrete quotients of ordinary AdS 3 . Moreover new solutions of this type, relevant to any theory with warped AdS 3 solutions, are exhibited. Finally we note that the black hole thermodynamics is consistent with the hypothesis that, for μl > 3, the warped AdS 3 ground state of TMG is holographically dual to a 2D boundary CFT with central charges c R -formula and c L -formula.

Full Text Available The politization ofḥadîth within social and political dimension has been in fact an undeniable matter since the beginning of the Islamic history. The proponents of Negara Islam Irak dan Suriah (NIIS [The Islamic State in Iraq and Syria (ISIS], as a modern political movement, claimḥadîth as one of their main religious, social, and political justifications, which is actually incongruous to the mainstream understanding of the global Muslim community. It is, therefore, a necessity to raise a discourse for analyzing the understanding of NIIS’s proponents onḥadîth based on the Method of Critique of Matn or Ma‘ânî al-H}adîth. The research focuses mainly on Dabiq magazine which is officially issued by the NIIS. It is analyzed descriptively, critically, and comparatively. The research concludes that the understanding of NIIS’s proponents onḥadîth on khilâfah, jihâd, hijrah, îmân and al-malh}amat al-kubrâ has erroneously deviated from the common and approved methods employed by the scholars ofḥadîth. NIIS’s understanding has been widely criticized by the scholars ofḥadîth of being partial, inconsistent, less careful, and has no theological, ideological and political root as well as historical evidences.

Asymptotically AdS spacetimes with a timelike Kasner singularity

Energy Technology Data Exchange (ETDEWEB)

Ren, Jie [Racah Institute of Physics, The Hebrew University of Jerusalem, Jerusalem 91904 (Israel)

2016-07-21

Exact solutions to Einstein’s equations for holographic models are presented and studied. The IR geometry has a timelike cousin of the Kasner singularity, which is the less generic case of the BKL (Belinski-Khalatnikov-Lifshitz) singularity, and the UV is asymptotically AdS. This solution describes a holographic RG flow between them. The solution’s appearance is an interpolation between the planar AdS black hole and the AdS soliton. The causality constraint is always satisfied. The entanglement entropy and Wilson loops are discussed. The boundary condition for the current-current correlation function and the Laplacian in the IR is examined. There is no infalling wave in the IR, but instead, there is a normalizable solution in the IR. In a special case, a hyperscaling-violating geometry is obtained after a dimensional reduction.

Mixed-symmetry arbitrary spin massive, massless, and self-dual massive fields in AdS(5) are studied. Light-cone gauge actions for such fields leading to decoupled equations of motion are constructed. Light-cone gauge formulation of mixed-symmetry anomalous conformal currents and shadows in 4d flat space is also developed. AdS/CFT correspondence for normalizable and non-normalizable modes of mixed-symmetry AdS fields and the respective boundary mixed-symmetry anomalous conformal currents and shadows is studied. We demonstrate that the light-cone gauge action for massive mixed-symmetry AdS field evaluated on solution of the Dirichlet problem amounts to the light-cone gauge 2-point vertex of mixed-symmetry anomalous shadow. Also we show that UV divergence of the action for mixed-symmetry massive AdS field with some particular value of mass parameter evaluated on the Dirichlet problem amounts to the action of long mixed-symmetry conformal field, while UV divergence of the action for mixed-symmetry massless AdS field evaluated on the Dirichlet problem amounts to the action of short mixed-symmetry conformal field. We speculate on string theory interpretation of a model which involves short low-spin conformal fields and long higher-spin conformal fields.

We construct a spinning closed string solution in AdS 5 x S 5 which is folded in the radial direction and has two equal spins in AdS 5 and a spin in S 5 . The energy expression of the three-spin solution specified by the folding and winding numbers for the small S 5 spin shows a logarithmic behavior and a one-third power behavior of the large total AdS 5 spin, in the long string and in the short string located near the boundary of AdS 5 respectively. It exhibits the non-regular expansion in the 't Hooft coupling constant, while it takes the regular one when the S 5 spin becomes large. (author)

Political theology: Possibility of comparison of the usage of death in theology and politics

Directory of Open Access Journals (Sweden)

Kuljić Todor

2014-01-01

Full Text Available This paper considers the epistemological value of the concept of political theology in thanatopolitics. The concept can be useful if one wants to interpret political usage of death. In addition to blurred boundaries between politics and theology, there is a more general and deeper socially integrative affinity between the two. In addition, there have been various politicizations of salvation in the past and in the present. Every political theology accentuates obedience as an immanent condition of salvation, although interpretation of death in political theology has a different function than in secular ideologies. In the centre of politically theological ideas one can find crosscutting of the divisions between public friend and public enemy from political world with similar divisions from religious world. Finally, beside the theological influence on politics, this paper considers some analogies between theology and the secular judiciary.

Noncommutative D-branes from covariant AdS superstring

International Nuclear Information System (INIS)

Sakaguchi, Makoto; Yoshida, Kentaroh

2008-01-01

We study noncommutative (NC) D-branes on AdS 5 xS 5 from κ-invariance of covariant Green-Schwarz action of an open string with a non-trivial world-volume flux. Finding boundary conditions to ensure the κ-invariance, we can see possible configurations of the NC D-branes. With this method 1/4 BPS NC D-branes are discussed. The resulting NC Dp-branes are 1/4 BPS at arbitrary position other than the p=1 case. The exceptional D-string is 1/2 BPS at the origin and 1/4 BPS outside the origin. Those are reduced to possible 1/4 BPS or 1/2 BPS AdS D-branes in the commutative limit. The same analysis is applied to an open superstring in a pp-wave and leads to 1/4 BPS configurations of NC D-branes. These D-branes are consistently obtained from AdS D-branes via the Penrose limit

Null infinity and extremal horizons in AdS-CFT

International Nuclear Information System (INIS)

Hickling, Andrew; Wiseman, Toby; Lucietti, James

2015-01-01

We consider AdS gravity duals to CFT on background spacetimes with a null infinity. Null infinity on the conformal boundary may extend to an extremal horizon in the bulk. For example it does so for Poincaré–AdS, although does not for planar Schwarzschild–AdS. If null infinity does extend into an extremal horizon in the bulk, we show that the bulk near-horizon geometry is determined by the geometry of the boundary null infinity. Hence the ‘infra-red’ geometry of the bulk is fixed by the large scale behaviour of the CFT spacetime. In addition the boundary stress tensor must have a particular decay at null infinity. As an application, we argue that for CFT on asymptotically flat backgrounds, any static bulk dual containing an extremal horizon extending from the boundary null infinity, must have the near-horizon geometry of Poincaré–AdS. We also discuss a class of boundary null infinity that cannot extend to a bulk extremal horizon, although we give evidence that they can extend to an analogous null surface in the bulk which possesses an associated scale-invariant ‘near-geometry’.

Infrared realization of dS2 in AdS2

Anninos, Dionysios; Hofman, Diego M.

2018-04-01

We describe a two-dimensional geometry that smoothly interpolates between an asymptotically AdS2 geometry and the static patch of dS2. We find this ‘centaur’ geometry to be a solution of dilaton gravity with a specific class of potentials for the dilaton. We interpret the centaur geometry as a thermal state in the putative quantum mechanics dual to the AdS2 evolved with the global Hamiltonian. We compute the thermodynamic properties and observe that the centaur state has finite entropy and positive specific heat. The static patch is the infrared part of the centaur geometry. We discuss boundary observables sensitive to the static patch region.

Conical singularities in AdS space time

International Nuclear Information System (INIS)

Ferreira, Cristine Nunes

2011-01-01

Full text: In recent years, the study of conformal gauge theories from 10-D has been motivated by the AdS d+1 /CFT d correspondence, first conjectured by J. Maldacena. The aim of this work is to consider the d = 4 case by analysing the configuration of the N coincident D3 branes. In this context, the work shows that there is a duality between type IIB string theory in AdS 5 x S 5 and N = 4 SU(N) Super Yang-Mills Theory in the IR. The AdS 5 /CFT 4 correspondence brought also new approaches to the strong coupling problem in QCD. Nowadays, there is a whole line of works that focus on the low dimensional correspondence AdS 4 /CFT 3 , like the application to graphene and topological insulators, and the AdS 3 /CFT 2 correspondence, related with the entanglement entropy. In this work, we consider the vortex configuration solution to the AdS 4 and AdS 3 space-time. The most important motivation is to discuss the boundary theory resulting from these solutions. We have examined a straightforward approach to a holographic computation of the graphene and entanglement entropy in the presence of the conical singularity. After this analysis, we consider the scalar field in the bulk in the presence of this metrics and work out the compactification modes. Taking the holographic point of view, we study and discuss the resulting Green function. (author)

Winding strings and AdS3 black holes

Troost, Jan

2002-01-01

We start a systematic study of string theory in AdS 3 black hole backgrounds. Firstly, we analyse in detail the geodesic structure of the BTZ black hole, including spacelike geodesics. Secondly, we study the spectrum for massive and massless scalar fields, paying particular attention to the connection between Sl(2,R) subgroups, the theory of special functions and global properties of the BTZ black holes. We construct classical strings that wind the black holes. Finally, we apply the general formalism to the vacuum black hole background, and formulate the boundary spacetime Virasoro algebra in terms of worldsheet operators. We moreover establish the link between a proposal for a ghost free spectrum for Sl(2,R) string propagation and the massless black hole background, thereby claryfing aspects of the AdS 3 /CFT correspondence.

AdS spacetime has been shown numerically to be unstable against a large class of arbitrarily small perturbations. In http://dx.doi.org/10.1103/PhysRevLett.114.071102, the authors presented a preliminary study of the effects on stability of changing the local dynamics by adding a Gauss-Bonnet term to the Einstein action. Here we provide further details as well as new results with improved numerical methods. In particular, we elucidate new structure in Choptuik scaling plots. We also provide evidence of chaotic behavior at the transition between immediate horizon formation and horizon formation after the matter pulse reflects from the AdS conformal boundary. Finally, we present data suggesting the formation of naked singularities in spacetimes with ADM mass below the algebraic bound for black hole formation.

Super-Galilean conformal algebra in AdS/CFT

International Nuclear Information System (INIS)

Sakaguchi, Makoto

2010-01-01

Galilean conformal algebra (GCA) is an Inoenue-Wigner (IW) contraction of a conformal algebra, while Newton-Hooke string algebra is an IW contraction of an Anti-de Sitter (AdS) algebra, which is the isometry of an AdS space. It is shown that the GCA is a boundary realization of the Newton-Hooke string algebra in the bulk AdS. The string lies along the direction transverse to the boundary, and the worldsheet is AdS 2 . The one-dimensional conformal symmetry so(2,1) and rotational symmetry so(d) contained in the GCA are realized as the symmetry on the AdS 2 string worldsheet and rotational symmetry in the space transverse to the AdS 2 in AdS d+2 , respectively. It follows from this correspondence that 32 supersymmetric GCAs can be derived as IW contractions of superconformal algebras, psu(2,2|4), osp(8|4), and osp(8*|4). We also derive less supersymmetric GCAs from su(2,2|2), osp(4|4), osp(2|4), and osp(8*|2).

The Kazakhstani Youth’s Engagement in Politics

Full Text Available Current research on the Kazakhstani youth’s political participation has usually been informed by a rather traditional understanding of the concept of political participation, without considering the impact of social media and other non-traditional forms of political engagement. This article advocates for a more nuanced understanding of political participation in the country, and particularly among the younger generation, who – it will be shown, display a wide interest in the political developments of the country and are possibly encouraged by a wider access to information and social media through the internet. By pushing the boundaries of political participation, we suggest that young Kazakhs are more active in political debates than usually considered by a number of previous studies.

For an effective AdS theory, we present a simple prescription to compute the renormalization of its dual boundary field theory. In particular, we define anomalous dimension holographically as the dependence of the wave-function renormalization factor on the radial cutoff in the Poincare patch of AdS. With this definition, the anomalous dimensions of both single- and double- trace operators are calculated. Three different dualities are considered with the field theory being CFT, CFT with a dou...

Exact microstate counting for dyonic black holes in AdS4

We present a counting of microstates of a class of dyonic BPS black holes in AdS4 which precisely reproduces their Bekenstein-Hawking entropy. The counting is performed in the dual boundary description, that provides a non-perturbative definition of quantum gravity, in terms of a twisted and mass-deformed ABJM theory. We evaluate its twisted index and propose an extremization principle to extract the entropy, which reproduces the attractor mechanism in gauged supergravity.

Good fences: the importance of setting boundaries for peaceful coexistence.

Directory of Open Access Journals (Sweden)

Alex Rutherford

Full Text Available We consider the conditions of peace and violence among ethnic groups, testing a theory designed to predict the locations of violence and interventions that can promote peace. Characterizing the model's success in predicting peace requires examples where peace prevails despite diversity. Switzerland is recognized as a country of peace, stability and prosperity. This is surprising because of its linguistic and religious diversity that in other parts of the world lead to conflict and violence. Here we analyze how peaceful stability is maintained. Our analysis shows that peace does not depend on integrated coexistence, but rather on well defined topographical and political boundaries separating groups, allowing for partial autonomy within a single country. In Switzerland, mountains and lakes are an important part of the boundaries between sharply defined linguistic areas. Political canton and circle (sub-canton boundaries often separate religious groups. Where such boundaries do not appear to be sufficient, we find that specific aspects of the population distribution guarantee either sufficient separation or sufficient mixing to inhibit intergroup violence according to the quantitative theory of conflict. In exactly one region, a porous mountain range does not adequately separate linguistic groups and that region has experienced significant violent conflict, leading to the recent creation of the canton of Jura. Our analysis supports the hypothesis that violence between groups can be inhibited by physical and political boundaries. A similar analysis of the area of the former Yugoslavia shows that during widespread ethnic violence existing political boundaries did not coincide with the boundaries of distinct groups, but peace prevailed in specific areas where they did coincide. The success of peace in Switzerland may serve as a model to resolve conflict in other ethnically diverse countries and regions of the world.

The Political Geography of Voters and Political Participation: Evidence from Local Election in Suburban Indonesia

Pitri Yandri

2017-07-01

Full Text Available The praxis of political issue including voter turnout and political participation does not exist in a vacuum. Therefore, geographical and spatial issues are frequently engaged and even embedded into it. Thus, this article is written with one purpose: to investigate the spatial relationship of voter turnout and their political participation. As stated earlier, the complexity of the political analysis based on geography will take us on a multidimensional approach that includes social, cultural and economy. However, this article starts the discussion from spatial analysis by using a map that illustrates the administrative boundaries of a region, then determining whether one region is adjacent to another. In this case, Moran’s I is used to determine the spatial autocorrelation of voter turnout and political participation. The result indicates that the voter turnout and political participation in one region are adjacent to each other. Possible reasons for the result are discussed in this article.

An attempt has been made to establish the potential of political publicity for the qualitative understanding of participatory democracy. The potential of the public sphere in the development of civil society and social capital has been described. The distinction between the public sphere of politics and political communication in the specific conditions of modern transformational societies has been reasonably grounded. The importance of the presence of state power in all spheres of life of the transformational society has been stressed. Such transformation has not been stoped after the liberal market reforms, which had to ensure the existence of a formal representative democracy. The influence of the elite and expert groups being the reason of the absence of really functioning future civil society has been considered. The features of the formation of civil and social activities as a precondition for the democratic political class’ functioning have been studied. The specifics of public political activity being the prerogative of the competent entities’ political broadcasting have been analyzed. The gradual formation of cyber public sphere and its political branch segment has been revealed. Thorough attention has been given to the processes of the public sphere’s politicization which are usual for primarily authoritarian and closed societies.

Social Boundaries and Secularism in the Lebanese Left

DEFF Research Database (Denmark)

2013-01-01

This article explores the social meaning of boundaries in Lebanon through debates about secularism in and around the Lebanese Left. The aim is to elucidate the political and social meaning of ‘Left’ in a Lebanese context, and the positioning of liminal political subjectivity in a system organized...... along sectarian boundaries. Based on readings of debates about secularism in 1975 and 1976, the article proposes that the Left has since that year been forced to embrace secularism as its primary ideological marker. This experience in turn has become constitutive for what it means to be a leftist...

Phase transition and thermodynamical geometry for Schwarzschild AdS black hole in AdS_5×S"5 spacetime

International Nuclear Information System (INIS)

Zhang, Jia-Lin; Cai, Rong-Gen; Yu, Hongwei

2015-01-01

We study the thermodynamics and thermodynamic geometry of a five-dimensional Schwarzschild AdS black hole in AdS_5×S"5 spacetime by treating the cosmological constant as the number of colors in the boundary gauge theory and its conjugate quantity as the associated chemical potential. It is found that the chemical potential is always negative in the stable branch of black hole thermodynamics and it has a chance to be positive, but appears in the unstable branch. We calculate the scalar curvatures of the thermodynamical Weinhold metric, Ruppeiner metric and Quevedo metric, respectively and we find that the scalar curvature in the Weinhold metric is always vanishing, while in the Ruppeiner metric the divergence of the scalar curvature is related to the divergence of the heat capacity with fixed chemical potential, and in the Quevedo metric the divergence of the scalar curvature is related to the divergence of the heat capacity with fixed number of colors and to the vanishing of the heat capacity with fixed chemical potential.

Bubbling AdS3

International Nuclear Information System (INIS)

Martelli, Dario; Morales, Jose Francisco

2005-01-01

In the light of the recent Lin, Lunin, Maldacena (LLM) results, we investigate 1/2-BPS geometries in minimal (and next to minimal) supergravity in D = 6 dimensions. In the case of minimal supergravity, solutions are given by fibrations of a two-torus T 2 specified by two harmonic functions. For a rectangular torus the two functions are related by a non-linear equation with rare solutions: AdS 3 x S 3 , the pp-wave and the multi-center string. 'Bubbling', i.e. superpositions of droplets, is accommodated by allowing the complex structure of the T 2 to vary over the base. The analysis is repeated in the presence of a tensor multiplet and similar conclusions are reached, with generic solutions describing D1D5 (or their dual fundamental string-momentum) systems. In this framework, the profile of the dual fundamental string-momentum system is identified with the boundaries of the droplets in a two-dimensional plane. (author)

Generalized added masses computation for fluid structure interaction

International Nuclear Information System (INIS)

Lazzeri, L.; Cecconi, S.; Scala, M.

1983-01-01

The aim of this paper a description of a method to simulate the dynamic effect of a fluid between two structures by means of an added mass and an added stiffness. The method is based on a potential theory which assumes the fluid is inviscid and incompressible (the case of compressibility is discussed); a solution of the corresponding field equation is given as a superposition of elementary conditions (i.e. applicable to elementary boundary conditions). Consequently the pressure and displacements of the fluid on the boundary are given as a function of the series coefficients; the ''work lost'' (i.e. the work done by the pressures on the difference between actual and estimated displacements) is minimized, in this way the expansion coefficients are related to the displacements on the boundaries. Virtual work procedures are then used to compute added masses. The particular case of a free surface (with gravity effects) is discussed, it is shown how the effect can be modelled by means of an added stiffness term. Some examples relative to vibrations in reservoirs are given and discussed. (orig.)

Heavy ion collisions in AdS5

International Nuclear Information System (INIS)

Kovchegov, Yuri V.

2011-01-01

We study heavy ion collisions at strong 't Hooft coupling using AdS/CFT correspondence. Heavy ion collisions correspond to gravitational shock wave collisions in AdS 5 . We construct the metric in the forward light cone after the collision perturbatively through expansion of Einstein equations in graviton exchanges. We obtain an analytic expression for the metric including all-order graviton exchanges with one shock wave, while keeping the exchanges with another shock wave at the lowest order. We read off the corresponding energy-momentum tensor of the produced medium. Unfortunately this energy-momentum tensor does not correspond to ideal hydrodynamics, indicating that higher order graviton exchanges are needed to construct the full solution of the problem. We also show that shock waves must completely stop almost immediately after the collision in AdS 5 , which, on the field theory side, corresponds to complete nuclear stopping due to strong coupling effects, likely leading to Landau hydrodynamics. Finally, we perform trapped surface analysis of the shock wave collisions demonstrating that a bulk black hole, corresponding to ideal hydrodynamics on the boundary, has to be created in such collisions, thus constructing a proof of thermalization in heavy ion collisions at strong coupling.

On supersymmetric AdS6 solutions in 10 and 11 dimensions

Gutowski, J.; Papadopoulos, G.

2017-12-01

We prove a non-existence theorem for smooth, supersymmetric, warped AdS 6 solutions with connected, compact without boundary internal space in D = 11 and (massive) IIA supergravities. In IIB supergravity we show that if such AdS 6 solutions exist, then the NSNS and RR 3-form fluxes must be linearly independent and certain spinor bilinears must be appropriately restricted. Moreover we demonstrate that the internal space admits an so(3) action which leaves all the fields invariant and for smooth solutions the principal orbits must have co-dimension two. We also describe the topology and geometry of internal spaces that admit such a so(3) action and show that there are no solutions for which the internal space has topology F × S 2, where F is an oriented surface.

The role of boundary organizations in co-management: examining the politics of knowledge integration in a marine protected area in Belize

Directory of Open Access Journals (Sweden)

Noella J. Gray

2016-08-01

Full Text Available Marine protected areas (MPAs are an increasingly popular tool for management of the marine commons. Effective governance is essential if MPAs are to achieve their objectives, yet many MPAs face conflicts and governance challenges, including lack of trust and knowledge integration between fishers, scientists, and policy makers. This paper considers the role of a boundary organization in facilitating knowledge integration in a co-managed MPA, the Gladden Spit and Silk Cayes Marine Reserve in Belize. Boundary organizations can play an important role in resource management, by bridging the science-policy divide, facilitating knowledge integration, and enabling communication in conditions of uncertainty. Drawing on ethnographic research conducted in Belize, the paper identifies four challenges for knowledge integration. First, actors have divergent perspectives on whether and how knowledge is being integrated. Second, actors disagree on resource conditions within the MPA and how these should be understood. Third, in order to maintain accountability with multiple actors, including fishers, government, and funders, the boundary organization has promoted the importance of different types of knowledge for different purposes (science and fishers’ knowledge, rather than the integration of these. Finally, a lack of trust and uneven power relations make it difficult to separate knowledge claims from political claims. However, even if knowledge integration proves difficult, boundary organizations may still play an important role by maintaining accountability, providing space for conflicting understandings to co-exist, and ultimately for governance institutions to evolve.

Closed string tachyons on AdS orbifolds and dual Yang-Mills instantons

Hikida, Y. [Deutsches Elektronen-Synchrotron (DESY), Hamburg (Germany); Iizuka, N. [California Univ., Santa Barbara, CA (United States). Kavli Inst. for Theoretical Physics

2007-06-15

We study the condensation of localized closed string tachyons on AdS orbifolds both from the bulk and boundary theory viewpoints. We first extend the known results for AdS{sub 5}/Z{sub k} to AdS{sub 3}/Z{sub k} case, and we proposed that the AdS{sub 3}/Z{sub k} decays into AdS{sub 3}/Z{sub k'} with k{sup '} < k. From the bulk viewpoint, we obtain a time-dependent gravity solution describing the decay of AdS orbifold numerically. From the dual gauge theory viewpoint, we calculated the Casimir energies of gauge theory vacua and it is found that their values are exactly the same as the masses of dual geometries, even though they are in different parameter regimes of 't Hooft coupling. We also consider AdS{sub 5} orbifold. The decay of AdS{sub 5}/Z{sub k} is dual to the transition between the vacua of dual gauge theory on R{sub t} x S{sup 3}/Z{sub k}. We constructed the instanton solutions describing the transitions by making use of instanton solutions on R{sub t} x S{sup 2}. (orig.)

Near-horizon limit of the charged BTZ black hole and AdS2 quantum gravity

International Nuclear Information System (INIS)

Cadoni, Mariano; Setare, Mohammad R.

2008-01-01

We show that the 3D charged Banados-Teitelboim-Zanelli (BTZ) black hole solution interpolates between two different 2D AdS spacetimes: a near-extremal, near-horizon AdS 2 geometry with constant dilaton and U(1) field and an asymptotic AdS 2 geometry with a linear dilaton. Thus, the charged BTZ black hole can be considered as interpolating between the two different formulations proposed until now for AdS 2 quantum gravity. In both cases the theory is the chiral half of a 2D CFT and describes, respectively, Brown-Hennaux-like boundary deformations and near-horizon excitations. The central charge c as of the asymptotic CFT is determined by 3D Newton constant G and the AdS length l, c as = 3l/G, whereas that of the near-horizon CFT also depends on the U(1) charge Q, c nh ∝lQ/√G.

Full Text Available This paper presents a theoretical link among green marketing of Teh Kotak ad, “Persembahan dari Alam” version. This is an ad telling as if the product of Teh Kotak is truly from nature. In addition, this research explored the portrayal of how this ad contains metaphorical element to juxtapose nature and technology as the same level. In the analysis, this study attempts to use Green marketing theory as a tool for analysis to explore what is the message behind the ad. Moreover, exploring the representation of the portion of the position of gender where the ad uses a woman as the main actor picking tea leaf, as if this ad looks natural. The result of the study revealed that Green marketing showed it competences to cover with political agenda. It is reflected in green image which told that The Kotak is a gift from nature. Overall, this study concludes that green image of this ad relays the hidden meaning, where the main aim is inviting people to buy its product as political agendas.

Closed-String Tachyons and the Hagedorn Transition in AdS Space

CERN Document Server

Barbón, José L F

2002-01-01

We discuss some aspects of the behaviour of a string gas at the Hagedorn temperature from a Euclidean point of view. Using AdS space as an infrared regulator, the Hagedorn tachyon can be effectively quasi-localized and its dynamics controled by a finite energetic balance. We propose that the off-shell RG flow matches to an Euclidean AdS black hole geometry in a generalization of the string/black-hole correspondence principle. The final stage of the RG flow can be interpreted semiclassically as the growth of a cool black hole in a hotter radiation bath. The end-point of the condensation is the large Euclidan AdS black hole, and the part of spacetime behind the horizon has been removed. In the flat-space limit, holography is manifest by the system creating its own transverse screen at infinity. This leads to an argument, based on the energetics of the system, explaining why the non-supersymmetric type 0A string theory decays into the supersymmetric type IIB vacuum. We also suggest a notion of `boundary entropy'...

Holographic dual of de Sitter universe with AdS bubbles

International Nuclear Information System (INIS)

Kanno, Sugumi; Sasaki, Misao; Soda, Jiro

2012-01-01

We study the proposal that a de Sitter (dS) universe with an Anti-de Sitter (AdS) bubble can be replaced by a dS universe with a boundary CFT. To explore this duality, we consider incident gravitons coming from the dS universe through the bubble wall into the AdS bubble in the original picture. In the dual picture, this process has to be identified with the absorption of gravitons by CFT matter. We have obtained a general formula for the absorption probability in general d+1 spacetime dimensions. The result shows the different behavior depending on whether spacetime dimensions are even or odd. We find that the absorption process of gravitons from the dS universe by CFT matter is controlled by localized gravitons (massive bound state modes in the Kaluza-Klein decomposition) in the dS universe. The absorption probability is determined by the effective degrees of freedom of the CFT matter and the effective gravitational coupling constant which encodes information of localized gravitons. We speculate that the dual of (d+1)-dimensional dS universe with an AdS bubble is also dual to a d-dimensional dS universe with CFT matter.

Quantum local quench, AdS/BCFT and Yo-Yo string

International Nuclear Information System (INIS)

Astaneh, Amin Faraji; Mosaffa, Amir Esmaeil

2015-01-01

We propose a holographic model for local quench in 1+1 dimensional Conformal Field Theory (CFT). The local quench is produced by joining two identical CFT’s on semi-infinite lines. When these theories have a zero boundary entropy, we use the AdS/Boundary CFT proposal to describe this process in terms of bulk physics. Boundaries of the original CFT’s are extended in AdS as dynamical surfaces. In our holographic picture these surfaces detach from the boundary and form a closed folded string which can propagate in the bulk. The dynamics of this string is governed by the tensionless Yo-Yo string solution and its subsequent evolution determines the time dependence after quench. We use this model to calculate holographic Entanglement Entropy (EE) of an interval as a function of time. We propose how the falling string deforms Ryu-Takayanagi’s curves. Using the deformed curves we calculate EE and find complete agreement with field theory results.

The Metastable City and the Politics of Crystallisation: Protesting and Policing in Kampala

Directory of Open Access Journals (Sweden)

Joschka Philipps

2016-01-01

Full Text Available When protests break out in downtown Kampala they tend to transform a fluid urban environment into bounded political camps, and myriad ambiguous concerns into comparatively clear-cut political issues. This article traces this process and conceptualises Kampala’s urban politics as a politics of crystallisation: as attempts to structure highly fluid dynamics into something concrete. The article is based on ethnographic research amongst opposition activists and the police forces. Both seek to activate political boundaries and make people gravitate towards their respective side. But in line with the fluidity of urban everyday life, they also work and collaborate across these boundaries. The national regime and the opposition thus function not as permanent, stable structures, but as processes, as fields of gravity whose emergence is incited and inhibited, financed, and policed. Drawing on Gilbert Simondon’s theory of individuation and AbdouMaliq Simone’s work on urbanity, this analytical framework offers a dynamic reading of urban contentious politics in general, and a reinterpretation of the paradoxes of power in African politics in particular.

Shock wave collisions and thermalization in AdS5

2011-01-01

We study heavy ion collisions at strong 't Hooft coupling using AdS/CFT correspondence. According to the AdS/CFT dictionary heavy ion collisions correspond to gravitational shock wave collisions in AdS 5 . We construct the metric in the forward light cone after the collision perturbatively through expansion of Einstein equations in graviton exchanges. We obtain an analytic expression for the metric including all-order graviton exchanges with one shock wave, while keeping the exchanges with another shock wave at the lowest order. We read off the corresponding energy-momentum tensor of the produced medium. Unfortunately this energy-momentum tensor does not correspond to ideal hydrodynamics, indicating that higher order graviton exchanges are needed to construct the full solution of the problem. We also show that shock waves must completely stop almost immediately after the collision in AdS 5 , which, on the field theory side, corresponds to complete nuclear stopping due to strong coupling effects, likely leading to Landau hydrodynamics. Finally, we perform trapped surface analysis of the shock wave collisions demonstrating that a bulk black hole, corresponding to ideal hydrodynamics on the boundary, has to be created in such collisions, thus constructing a proof of thermalization in heavy ion collisions at strong coupling.

Mass, angular momentum and thermodynamics in four-dimensional Kerr-AdS black holes

Energy Technology Data Exchange (ETDEWEB)

Olea, Rodrigo [Departamento de Fisica, Pontificia Universidad Catolica de Chile, Casilla 306, Santiago 22 (Chile)

2005-06-01

In this paper, the connection between the Lorentz-covariant counterterms that regularize the four-dimensional AdS gravity action and topological invariants is explored. It is shown that demanding the spacetime to have a negative constant curvature in the asymptotic region permits the explicit construction of such series of boundary terms. The orthonormal frame is adapted to appropriately describe the boundary geometry and, as a result, the boundary term can be expressed as a functional of the boundary metric, extrinsic curvature and intrinsic curvature. This choice also allows to write down the background-independent Noether charges associated to asymptotic symmetries in standard tensorial formalism. The absence of the Gibbons-Hawking term is a consequence of an action principle based on a boundary condition different than Dirichlet on the metric. This argument makes plausible the idea of regarding this approach as an alternative regularization scheme for AdS gravity in all even dimensions, different than the standard counterterms prescription. As an illustration of the finiteness of the charges and the euclidean action in this framework, the conserved quantities and black hole entropy for four-dimensional Kerr-AdS are computed.

A rotating hairy AdS3 black hole with the metric having only one Killing vector field

Iizuka, Norihiro; Ishibashi, Akihiro; Maeda, Kengo

2015-01-01

We perturbatively construct a three-dimensional rotating AdS black hole with a real scalar hair. We choose the mass of a scalar field slightly above the Breitenlohner-Freedman bound and impose a general boundary condition for the bulk scalar field at AdS infinity. We first show that rotating BTZ black holes are unstable against scalar field perturbations under our more general boundary condition. Next we construct a rotating hairy black hole perturbatively with respect to a small amplitude ϵ of the scalar field, up to O(ϵ 4 ). Our hairy black hole is stationary and exhibits no dissipation, but the lumps of the non-linearly perturbed geometry break axial symmetry, thus providing the first example of a rotating black hole whose metric admits only one Killing vector field. Furthermore, we numerically show that the entropy of our hairy black hole is larger than that of the BTZ black hole with the same energy and the angular momentum. We briefly discuss if our rotating hairy black hole in lumpy geometry could be the endpoint of the instability.

Conformally coupled scalars, instantons and vacuum instability in AdS{sub 4}

We show that a scalar field conformally coupled to AdS gravity in four dimensions with a quartic self-interaction can be embedded into M-theory. The holographic effective action and effective potential are exactly calculated, allowing us to study non-perturbatively the stability of AdS{sub 4} in the presence of the conformally coupled scalar. It is shown that there exists a one-parameter family of conformal scalar boundary conditions for which the boundary theory has an unstable vacuum. In this case, the bulk theory has instanton solutions that mediate the decay of the AdS{sub 4} space. These results match nicely with the vacuum structure and the existence of instantons in an effective three-dimensional boundary model.

Questioning Appropriation: Agency and Complicity in a Transnational Feminist Location Politics

Directory of Open Access Journals (Sweden)

Joe Parker

2012-12-01

Full Text Available In feminist circles agency is often opposed to complicity and associated with resistance to sexism and patriarchy, yet such binary oppositions make the political stakes of their presumed boundaries difficult to interrogate. By bringing location politics into dialogue with agency theory, boundaries of same/Other and location categories may move from a naturalized ground for political work to the contested center of a politics of resistance. I follow a Foucauldian interpretation of agency to reconsider the ethico-politics of established divisions of self and Other both individually and in terms of social movements. By following Gayatri Spivak, Meyda Yeğenoğlu, and Chandra Mohanty's transnational feminist politics, I argue for the refusal of totalizing binaries and for careful attention to unavoidable complicities. This makes possible practices of agency that can critique the political and ethical limits and effects of its epistemology and take as its central project the intervention into appropriations of the Others into modern notions of the "real." The resulting reconstitution of self-Other relations in their work opens up important new avenues for building social movements that acknowledge difference within the subject or the movement rather than deny and expel their Others.

Analog geometry in an expanding fluid from AdS/CFT perspective

Science.gov (United States)

Bilić, Neven; Domazet, Silvije; Tolić, Dijana

2015-04-01

The dynamics of an expanding hadron fluid at temperatures below the chiral transition is studied in the framework of AdS/CFT correspondence. We establish a correspondence between the asymptotic AdS geometry in the 4 + 1 dimensional bulk with the analog spacetime geometry on its 3 + 1 dimensional boundary with the background fluid undergoing a spherical Bjorken type expansion. The analog metric tensor on the boundary depends locally on the soft pion dispersion relation and the four-velocity of the fluid. The AdS/CFT correspondence provides a relation between the pion velocity and the critical temperature of the chiral phase transition.

Logarithmic corrections to entropy and AdS/CFT

Abstract. We calculate the correction to the Bekenstein-Hawking entropy formula for five-dimensional AdS-Schwarzschild black holes due to thermodynamic fluctuations. The result is then compared with the boundary gauge theory entropy corrections via AdS/CFT correspondence.

Mode solutions for a Klein-Gordon field in anti-de Sitter spacetime with dynamical boundary conditions of Wentzell type

Science.gov (United States)

Dappiaggi, Claudio; Ferreira, Hugo R. C.; Juárez-Aubry, Benito A.

2018-04-01

We study a real, massive Klein-Gordon field in the Poincaré fundamental domain of the (d +1 )-dimensional anti-de Sitter (AdS) spacetime, subject to a particular choice of dynamical boundary conditions of generalized Wentzell type, whereby the boundary data solves a nonhomogeneous, boundary Klein-Gordon equation, with the source term fixed by the normal derivative of the scalar field at the boundary. This naturally defines a field in the conformal boundary of the Poincaré fundamental domain of AdS. We completely solve the equations for the bulk and boundary fields and investigate the existence of bound state solutions, motivated by the analogous problem with Robin boundary conditions, which are recovered as a limiting case. Finally, we argue that both Robin and generalized Wentzell boundary conditions are distinguished in the sense that they are invariant under the action of the isometry group of the AdS conformal boundary, a condition which ensures in addition that the total flux of energy across the boundary vanishes.

What makes an ad a cigarette ad? Commercial tobacco imagery in the lesbian, gay, and bisexual press

Science.gov (United States)

Smith, E.; Offen, N.; Malone, R.

2005-01-01

Objectives: To determine the extent of commercial tobacco imagery in the lesbian, gay, and bisexual (LGB) press. Methods: Content analysis of all advertising containing tobacco related text or imagery in 20 LGB community periodicals, published between January 1990 and December 2000. Results: 3428 ads were found: 689 tobacco product ads, 1607 ads for cessation products or services, 99 ads with a political message about tobacco, and 1033 non-tobacco ads that showed tobacco (NAST). Although cessation ads were numerically dominant, tobacco product ads and NAST occupied more space and were more likely to use images. NAST almost never had an anti-tobacco message. Formal sponsorship between tobacco and other companies was very rare. Lesbian periodicals had proportionally more NAST and fewer cessation ads. Conclusions: Cigarette ads were outnumbered by NAST. Although these ads do not usually show brands, and are unlikely to be the result of formal sponsorship agreements, they may be "selling" smoking. Tobacco control advocates should persuade editors to refuse tobacco product ads and those with gratuitous tobacco imagery. PMID:16286500

Full Text Available The role of political knowledge in engendering political participation among youths in a society cannot be overstated. Yet, there is scarcity of research in this area. Thus, this study assessed the moderating role of political knowledge in the relationship between Access to Political Information on Facebook and Twitter (APIFT, Political Interest (PI and Policy Satisfaction (PS with Online Political Participation on Facebook and Twitter (OPPFT. A cross-sectional survey was conducted on 238 undergraduate students of Universiti Utara Malaysia. Questionnaire was used to collect data which was analysed using Partial Least Squares-MultiGroup Analysis (PLS-MGA. Results revealed that political knowledge moderated the relationship between access to political information on Facebook and Twitter and political interest with youth online political participation on Facebook and Twitter. However, it did not moderate the relationship between policy satisfaction with youth online political participation on Facebook and Twitter. Generally, these findings suggests that political knowledge plays a significant role in youth online political participation in Malaysia. Consequently, this study has added empirical evidence to predictors of political participation while at the same time contributing to the body of knowledge on online political participation.

Nonlocal String Theories on AdS3 x S3 and Stable Non-Supersymmetric Backgrounds

International Nuclear Information System (INIS)

Silverstein, Eva M

2002-01-01

We exhibit a simple class of exactly marginal ''double-trace'' deformations of two dimensional CFTs which have AdS 3 duals, in which the deformation is given by a product of left and right-moving U(1) currents. In this special case the deformation on AdS 3 is generated by a local boundary term in three dimensions, which changes the physics also in the bulk via bulk-boundary propagators. However, the deformation is non-local in six dimensions and on the string worldsheet, like generic non-local string theories (NLSTs). Due to the simplicity of the deformation we can explicitly make computations in the non-local string theory and compare them to CFT computations, and we obtain precise agreement. We discuss the effect of the deformation on closed strings and on D-branes. The examples we analyze include a supersymmetry-breaking but exactly marginal ''double-trace'' deformation, which is dual to a string theory in which no destabilizing tadpoles are generated for moduli nonperturbatively in all couplings, despite the absence of supersymmetry. We explain how this cancellation works on the gravity side in string perturbation theory, and also non-perturbatively at leading order in the deformation parameter. We also discuss possible flat space limits of our construction

Scalar field theory in the AdS/CFT correspondence revisited

International Nuclear Information System (INIS)

Minces, Pablo; Rivelles, Victor O.

2000-01-01

We consider the role of boundary conditions in the AdS d+1 /CFT d correspondence for the scalar field theory. Also a careful analysis of some limiting cases is presented. We study three possible types of boundary conditions, Dirichlet, Neumann and mixed. We compute the two-point functions of the conformal operators on the boundary for each type of boundary condition. We show how particular choices of the mass require different treatments. In the Dirichlet case we find that there is no double zero in the two-point function of the operator with conformal dimension d/2. The Neumann case leads to new normalizations for the boundary two-point functions. In the massless case we show that the conformal dimension of the boundary conformal operator is precisely the unitarity bound for scalar operators. We find a one-parameter family of boundary conditions in the mixed case. There are again new normalizations for the boundary two-point functions. For a particular choice of the mixed boundary condition and with the mass squared in the range -d 2 /4 2 2 /4+1 the boundary operator has conformal dimension comprised in the interval [(d-2)/2, d/2]. For mass squared m 2 >-d 2 /4+1 the same choice of mixed boundary condition leads to a boundary operator whose conformal dimension is the unitarity bound

In particular, we study the two point function of a fermionic operator in nonrelativistic CFTs by making use of a massive fermion propagating in geometries with Schroedinger group isometry. Although the boundary of the geometries with Schroedinger group isometry differ from that in AdS geometries where the dictionary of AdS/CFT is established, using the general procedure of AdS/CFT correspondence, we see that the resultant two point function has the expected form for fermionic operators in nonrelativistic CFTs, though a nontrivial regularization may be needed.

This study examines the relationship between exposure to political personalized ads on Facebook and voters' responses toward those ads and studies the mediating role of the use of persuasion knowledge in this relationship. Results from an online experiment (N = 122) demonstrate that exposure to a personalized ad from a political party activates persuasion knowledge, which in turn leads to lower intentions to engage in electronic word of mouth, but only for those participants who recall seeing the Sponsored label. We found no effects on source trustworthiness. Adding a text explaining the practice of personalized advertising did not lead to higher levels of persuasion knowledge and did not change the responses toward the message.

We construct a family of very simple stationary solutions to gravity coupled to a massless scalar field in global AdS. They involve a constantly rising source for the scalar field at the boundary and thereby we name them pumping solutions. We construct them numerically in D=4. They are regular and, generically, have negative mass. We perform a study of linear and nonlinear stability and find both stable and unstable branches. In the latter case, solutions belonging to different sub-branches can either decay to black holes or to limiting cycles. This observation motivates the search for non-stationary exactly time-periodic solutions which we actually construct. We clarify the role of pumping solutions in the context of quasistatic adiabatic quenches. In D=3 the pumping solutions can be related to other previously known solutions, like magnetic or translationally-breaking backgrounds. From this we derive an analytic expression.

Crystal manyfold universes in /AdS space

Science.gov (United States)

Kaloper, N.

2000-02-01

We derive crystal braneworld solutions, comprising of intersecting families of parallel /n+2-branes in a /4+n-dimensional /AdS space. Each family consists of alternating positive and negative tension branes. In the simplest case of exactly orthogonal families, there arise different crystals with unbroken /4D Poincaré invariance on the intersections, where our world can reside. A crystal can be finite along some direction, either because that direction is compact, or because it ends on a segment of /AdS bulk, or infinite, where the branes continue forever. If the crystal is interlaced by connected /3-branes directed both along the intersections and orthogonal to them, it can be viewed as an example of a Manyfold universe proposed recently by Arkani-Hamed, Dimopoulos, Dvali and the author. There are new ways for generating hierarchies, since the bulk volume of the crystal and the lattice spacing affect the /4D Planck mass. The low energy physics is sensitive to the boundary conditions in the bulk, and has to satisfy the same constraints discussed in the Manyfold universe. Phenomenological considerations favor either finite crystals, or crystals which are infinite but have broken translational invariance in the bulk. The most distinctive signature of the bulk structure is that the bulk gravitons are Bloch waves, with a band spectrum, which we explicitly construct in the case of a /5-dimensional theory.

Political Corruption, Democratic Theory, and Democracy

Directory of Open Access Journals (Sweden)

Doron Navot

2014-09-01

Full Text Available According to recent conceptual proposals, institutional corruption should be understood within the boundaries of the institution and its purpose. Political corruption in democracies, prominent scholars suggest, is characterized by the violation of institutional ideals or behaviors that tend to harm democratic processes and institutions. This paper rejects the idea that compromises, preferences, political agreements, or consent can be the baseline of conceptualization of political corruption. In order to improve the identification of abuse of power, the concept of political corruption should not be related directly to democratic institutions and processes; rather, it should be related to ideals whose content is independent of citizens’ preferences, institutions and processes. More specifically, I articulate the relations between political corruption and the notion of subjection, and include powerful citizens in the category of political corruption. Yet, I also suggest redefining under what conditions agents are culpable for their motivations in promoting private gain. By doing this, we better realize how democratic institutions can be the source of corruption and not just its victims. Such a redefinition, I propose finally, is the basis for the distinction between individual and institutional corruption.

Dirac perturbations on Schwarzschild-anti-de Sitter spacetimes: Generic boundary conditions and new quasinormal modes

Science.gov (United States)

Wang, Mengjie; Herdeiro, Carlos; Jing, Jiliang

2017-11-01

We study Dirac quasinormal modes of Schwarzschild-anti-de Sitter (Schwarzschild-AdS) black holes, following the generic principle for allowed boundary conditions proposed in [M. Wang, C. Herdeiro, and M. O. P. Sampaio, Phys. Rev. D 92, 124006 (2015)., 10.1103/PhysRevD.92.124006]. After deriving the equations of motion for Dirac fields on the aforementioned background, we impose vanishing energy flux boundary conditions to solve these equations. We find a set of two Robin boundary conditions are allowed. These two boundary conditions are used to calculate Dirac normal modes on empty AdS and quasinormal modes on Schwarzschild-AdS black holes. In the former case, we recover the known normal modes of empty AdS; in the latter case, the two sets of Robin boundary conditions lead to two different branches of quasinormal modes. The impact on these modes of the black hole size, the angular momentum quantum number and the overtone number are discussed. Our results show that vanishing energy flux boundary conditions are a robust principle, applicable not only to bosonic fields but also to fermionic fields.

Twistor methods for AdS{sub 5}

We consider the application of twistor theory to five-dimensional anti-de Sitter space. The twistor space of AdS{sub 5} is the same as the ambitwistor space of the four-dimensional conformal boundary; the geometry of this correspondence is reviewed for both the bulk and boundary. A Penrose transform allows us to describe free bulk fields, with or without mass, in terms of data on twistor space. Explicit representatives for the bulk-to-boundary propagators of scalars and spinors are constructed, along with twistor action functionals for the free theories. Evaluating these twistor actions on bulk-to-boundary propagators is shown to produce the correct two-point functions.

Advertising health: the case for counter-ads.

Science.gov (United States)

Dorfman, L; Wallack, L

1993-01-01

Public service advertisements have been used by many in hopes of "selling" good health behaviors. But selling good behavior--even if it could be done more effectively--is not the best goal for using mass media to prevent health problems. Personal behavior is only part of what determines health status. Social conditions and the physical environment are important determinants of health that are usually ignored by health promotion advertising. Public service advertising may be doing more harm than good if it is diverting attention from more effective socially based health promotion strategies. Counter-ads are one communications strategy that could be used to promote a broader responsibility for rectifying health problems. In the tradition of advocacy advertising directly promoting policy rather than products, counter-ads promote views consistent with a public health perspective. Counter-ads set the agenda for health issues, conferring status on policy-oriented strategies for addressing health problems. The primary purpose of counter-ads is to challenge the dominant view that public health problems reflect personal health habits. They are controversial because they place health issues in a social and political context. Advertising strategies for health promotion range over a spectrum from individually oriented public service advertising to socially oriented counter-advertising. The recent anti-tobacco campaign from the California Department of Health Services represents advertisements across the spectrum. Counter-ads that focus on a politically controversial definition for health problems are an appropriate and necessary alternative to public service advertising. PMID:8265756

Gender, religion and democratic politics in India.

Science.gov (United States)

Hasan, Zoya

2010-01-01

This article examines the impact of identity politics on gender equality. More specifically it explores the paradoxical and complex relationship of religion and politics in a multi-religious society and the complicated ways in which women's activism has both reinforced and challenged their gender identities. Contrary to the argument that religious politics does not always negate gender equality, the article argues that the Hindu religious politics and women's activism associated with it provides a compelling example of the instrumentalisation of women to accomplish the political goals of the Hindu right. It also examines the approach and strategies of influential political parties, women's organisations and Muslim women's groups towards legal reform and the contested issue of a uniform civil code. Against those who argue that, in the current communal conjuncture, reform within Muslim personal laws or Islamic feminism is the best strategy for enhancing the scope of Muslim women's rights, the article argues that such an approach tends to freeze identities within religious boundaries. It shows how women's and minority rights are used within the politics of religion to sideline the agenda of women's rights.

An investigation of AdS2 backreaction and holography

We investigate a dilaton gravity model in AdS 2 proposed by Almheiri and Polchinski http://dx.doi.org/10.1007/JHEP11(2015)014 and develop a 1d effective description in terms of a dynamical boundary time with a Schwarzian derivative action. We show that the effective model is equivalent to a 1d version of Liouville theory, and investigate its dynamics and symmetries via a standard canonical framework. We include the coupling to arbitrary conformal matter and analyze the effective action in the presence of possible sources. We compute commutators of local operators at large time separation, and match the result with the time shift due to a gravitational shockwave interaction. We study a black hole evaporation process and comment on the role of entropy in this model.

Bidirectional holographic codes and sub-AdS locality

Tensor networks implementing quantum error correcting codes have recently been used to construct toy models of holographic duality explicitly realizing some of the more puzzling features of the AdS/CFT correspondence. These models reproduce the Ryu-Takayanagi entropy formula for boundary intervals, and allow bulk operators to be mapped to the boundary in a redundant fashion. These exactly solvable, explicit models have provided valuable insight but nonetheless suffer from many deficiencies, some of which we attempt to address in this article. We propose a new class of tensor network models that subsume the earlier advances and, in addition, incorporate additional features of holographic duality, including: (1) a holographic interpretation of all boundary states, not just those in a “code” subspace, (2) a set of bulk states playing the role of “classical geometries” which reproduce the Ryu-Takayanagi formula for boundary intervals, (3) a bulk gauge symmetry analogous to diffeomorphism invariance in gravitational theories, (4) emergent bulk locality for sufficiently sparse excitations, and (5) the ability to describe geometry at sub-AdS resolutions or even flat space.

Einstein black holes, free scalars, and AdS/CFT correspondence

International Nuclear Information System (INIS)

Louko, Jorma; Wisniewski, Jacek

2004-01-01

We investigate AdS/CFT correspondence for two families of Einstein black holes in d≥4 dimensions, modeling the boundary conformal field theory by a free conformal scalar field and evaluating the boundary two-point function in the bulk geodesic approximation. For the d≥4 counterpart of the nonrotating Banados-Teitelboim-Zanelli hole and for its Z 2 quotient, the boundary state is thermal in the expected sense, and its stress-energy reflects the properties of the bulk geometry and suggests a novel definition for the mass of the hole. For the generalized Schwarzschild-AdS hole with a flat horizon of topology R d-2 , the boundary stress-energy has a thermal form with energy density proportional to the hole Arnowitt-Deser-Misner mass, but stress-energy corrections from compactified horizon dimensions cannot be consistently included at least for d=5

Test of the local form of higher-spin equations via AdS/CFT

Directory of Open Access Journals (Sweden)

2017-12-01

Full Text Available The local form of higher-spin equations found recently to the second order [1] is shown to properly reproduce the anticipated AdS/CFT correlators for appropriate boundary conditions. It is argued that consistent AdS/CFT holography for the parity-broken boundary models needs a nontrivial modification of the bosonic truncation of the original higher-spin theory with the doubled number of fields, as well as a nonlinear deformation of the boundary conditions in the higher orders.

Unitary Supermultiplets of $OSp(8^{*}|4)$ and the $AdS_{7}/CFT_{6}$ Duality

We study the unitary supermultiplets of the N=4 d=7 anti-de Sitter (AdS_7) superalgebra OSp(8^*|4), with the even subalgebra SO(6,2) X USp(4), which is the symmetry superalgebra of M-theory on AdS_7 X S^4. We give a complete classification of the positive energy doubleton and massless supermultiplets of OSp(8^*|4) . The ultra-short doubleton supermultiplets do not have a Poincaré limit in AdS_7 and correspond to superconformal field theories on the boundary of AdS_7 which can be identified with d=6 Minkowski space. We show that the six dimensional Poincare mass operator vanishes identically for the doubleton representations. By going from the compact U(4) basis of SO^*(8)=SO(6,2) to the noncompact basis SU^*(4)XD (d=6 Lorentz group times dilatations) one can associate the positive (conformal) energy representations of SO^*(8) with conformal fields transforming covariantly under the Lorentz group in d=6. The oscillator method used for the construction of the unitary supermultiplets of OSp(8^*|4) can be given ...

Conformal symmetry relates the metric on AdS{sub 2}×S{sup 1} to that of S{sup 3}. This implies that under a suitable choice of boundary conditions for fields on AdS{sub 2} the partition function of conformal field theories on these spaces must agree which makes AdS{sub 2}×S{sup 1} a good testing ground to study localization on non-compact spaces. We study supersymmetry on AdS{sub 2}×S{sup 1} and determine the localizing Lagrangian for N=2 supersymmetric Chern-Simons theory on AdS{sub 2}×S{sup 1}. We evaluate the partition function of N=2 supersymmetric Chern-Simons theory on AdS{sub 2}×S{sup 1} using localization, where the radius of S{sup 1} is q times that of AdS{sub 2}. With boundary conditions on AdS{sub 2}×S{sup 1} which ensure that all the physical fields are normalizable and lie in the space of square integrable wave functions in AdS{sub 2}, the result for the partition function precisely agrees with that of the theory on the q-fold covering of S{sup 3}.

Political construction of technology

In the 1970s radioactive waste disposal became a controversial scientific and social issue in the United States, after the US Atomic Energy Commission (AEC) charged with the development, regulation and promotion of nuclear technology, had tried to implement its disposal technology near Lyons, Kansas. This study traces the emergence of this controversy as part of the long-term development of the US radioactive waste disposal technology. Radioactive waste was not always considered a problem, and different meanings were attached to radwaste in the 1940s and early 1950s. Problem definitions and technical designs that underlaid this technology can be reconstructed, and its possible to show how some definitions received attention and others not, and how some became, and remained, dominant. During the process of problem definition, views compete, agendas are built, resources are allocated, and boundaries are created and maintained between 'inside' and 'outside world'. This is a political process, and by heuristically using concepts from political science and recent technology studies, the Political Construction of US radioactive waste disposal technologically can be reconstructed.

Holographic Rényi entropy in AdS3/LCFT2 correspondence

International Nuclear Information System (INIS)

Chen, Bin; Song, Feng-yan; Zhang, Jia-ju

2014-01-01

The recent study in AdS 3 /CFT 2 correspondence shows that the tree level contribution and 1-loop correction of holographic Rényi entanglement entropy (HRE) exactly match the direct CFT computation in the large central charge limit. This allows the Rényi entanglement entropy to be a new window to study the AdS/CFT correspondence. In this paper we generalize the study of Rényi entanglement entropy in pure AdS 3 gravity to the massive gravity theories at the critical points. For the cosmological topological massive gravity (CTMG), the dual conformal field theory (CFT) could be a chiral conformal field theory or a logarithmic conformal field theory (LCFT), depending on the asymptotic boundary conditions imposed. In both cases, by studying the short interval expansion of the Rényi entanglement entropy of two disjoint intervals with small cross ratio x, we find that the classical and 1-loop HRE are in exact match with the CFT results, up to order x 6 . To this order, the difference between the massless graviton and logarithmic mode can be seen clearly. Moreover, for the cosmological new massive gravity (CNMG) at critical point, which could be dual to a logarithmic CFT as well, we find the similar agreement in the CNMG/LCFT correspondence. Furthermore we read the 2-loop correction of graviton and logarithmic mode to HRE from CFT computation. It has distinct feature from the one in pure AdS 3 gravity

We present the complete family of solutions of 3D gravity (Λ<0) with two asymptotically AdS exterior regions. The solutions are constructed from data at the two boundaries, which correspond to two independent and arbitrary stress tensors T{sub R},T-bar{sub R}, and T{sub L},T-bar{sub L}. The two exteriors are smoothly joined on to an interior region through a regular horizon. We find CFT duals of these geometries which are entangled states of two CFT’s. We compute correlators between general operators at the two boundaries and find perfect agreement between CFT and bulk calculations. We calculate and match the CFT entanglement entropy (EE) with the holographic EE which involves geodesics passing through the wormhole. We also compute a holographic, non-equilibrium entropy for the CFT using properties of the regular horizon. The construction of the bulk solutions here uses an exact version of Brown-Henneaux type diffeomorphisms which are asymptotically nontrivial and transform the CFT states by two independent unitary operators on the two sides. Our solutions provide an infinite family of explicit examples of the ER=EPR relation of Maldacena and Susskind http://dx.doi.org/10.1002/prop.201300020.

AdS/CFT prescription for angle-deficit space and winding geodesics

Aref’eva, Irina Ya.; Khramtsov, Mikhail A.

2016-01-01

We present the holographic computation of the boundary two-point correlator using the GKPW prescription for a scalar field in the AdS_3 space with a conical defect. Generally speaking, a conical defect breaks conformal invariance in the dual theory, however we calculate the classical bulk-boundary propagator for a scalar field in the space with conical defect and use it to compute the two-point correlator in the boundary theory. We compare the obtained general expression with previous studies based on the geodesic approximation. They are in good agreement for short correlators, and main discrepancy comes in the region of long correlations. Meanwhile, in case of ℤ_r-orbifold, the GKPW result coincides with the one obtained via geodesic images prescription and with the general result for the boundary theory, which is conformal in this special case.

2014-01-01

This article analyzes the relationship between science and politics in Spain in the early 20th century from the perspective of the Social Contract for Science. The article shows that a genuine social contract for science was instituted in Spain during this period, although some boundary and integrity problems emerged. These problems are analyzed, showing that the boundary problems were a product of the conservative viewpoint on the relationship between science and politics, while the integrity problems involved the activation of networks of influence in the awarding of scholarships to study abroad. Finally, the analysis reveals that these problems did not invalidate the Spanish social contract for science.

Flores, J.L.; Sanchez, M.

2008-01-01

A complete and systematic approach to compute the causal boundary of wave-type spacetimes is carried out. The case of a 1-dimensional boundary is specially analyzed and its critical appearance in pp-wave type spacetimes is emphasized. In particular, the corresponding results obtained in the framework of the AdS/CFT correspondence for holography on the boundary, are reinterpreted and very widely generalized. Technically, a recent new definition of causal boundary is used and stressed. Moreover, a set of mathematical tools is introduced (analytical functional approach, Sturm-Liouville theory, Fermat-type arrival time, Busemann-type functions)

Temperature jump boundary conditions in radiation diffusion

International Nuclear Information System (INIS)

Alonso, C.T.

1976-12-01

The radiation diffusion approximation greatly simplifies radiation transport problems. Yet the application of this method has often been unnecessarily restricted to optically thick regions, or has been extended through the use of such ad hoc devices as flux limiters. The purpose of this paper is to review and draw attention to the use of the more physically appropriate temperature jump boundary conditions for extending the range of validity of the diffusion approximation. Pioneering work has shown that temperature jump boundary conditions remove the singularity in flux that occurs in ordinary diffusion at small optical thicknesses. In this review paper Deissler's equations for frequency-dependent jump boundary conditions are presented and specific geometric examples are calculated analytically for steady state radiation transfer. When jump boundary conditions are applied to radiation diffusion, they yield exact solutions which are naturally flux- limited and geometry-corrected. We believe that the presence of temperature jumps on source boundaries is probably responsible in some cases for the past need for imposing ad hoc flux-limiting constraints on pure diffusion solutions. The solution for transfer between plane slabs, which is exact to all orders of optical thickness, also provides a useful tool for studying the accuracy of computer codes

Graphical abstract: Display Omitted Highlights: → Amphiphilic carbon nanofiber membrane employed in electro-synthesis. → Triple phase boundary process within a carbon membrane. → Electrochemical deuteration in a liquid|liquid micro-reactor system. → Triple phase boundary reaction zone effects in electro-synthesis. - Abstract: An amphiphilic carbon nanofibre membrane electrode (ca. 50 nm fibre diameter, 50-100 μm membrane thickness) is employed as an active working electrode and separator between an aqueous electrolyte phase (with reference and counter electrode) and an immiscible organic acetonitrile phase (containing only the redox active material). Potential control is achieved with a reference and counter electrode located in the aqueous electrolyte phase, but the electrolysis is conducted in the organic acetonitrile phase in the absence of intentionally added supporting electrolyte. For the one-electron oxidation of n-butylferrocene coupled to perchlorate anion transfer from aqueous to organic phase effective electrolysis is demonstrated with an apparent mass transfer coefficient of m = 4 x 10 -5 m s -1 and electrolysis of typically 1 mg n-butylferrocene in a 100 μL volume. For the two-electron reduction of tetraethyl-ethylenetetracarboxylate the apparent mass transfer coefficient m = 4 x 10 -6 m s -1 is lower due to a less extended triple phase boundary reaction zone in the carbon nanofibre membrane. Nevertheless, effective electrolysis of up to 6 mg tetraethyl-ethylenetetracarboxylate in a 100 μL volume is demonstrated. Deuterated products are formed in the presence of D 2 O electrolyte media. The triple phase boundary dominated mechanism and future microreactor design improvements are discussed.

Prosumption as a Political Practice in a “Producer-Consumer Environment”

N V Plotichkina

2013-12-01

Full Text Available In this paper prosumption is characterized as a political practice in “producer-consumer” communities. Digital political prosumption is the result of the dissemination of Web 2.0., new social media, and 3.0. marketing. Political prosumption can develop in such forms as: the production of media political content (public journalism, political blogging, open news, citizens’ participation in ‘occupy’ movements and pirate parties. The principles of digital prosumption in politics are as follows: openness for public participation, assessment by communities, heterarchy, ad-hoc-meritocracy, common property, and personal service of community members. The appearing new forms of citizen participation are considered to be a transition to a democratic net society structure based on prosumption.

Gauge boson exchange in AdSd+1

D'Hoker, Eric; Freedman, Daniel Z.

1999-01-01

We study the amplitude for exchange of massless gauge bosons between pairs of massive scalar fields in anti-de Sitter space. In the AdS/CFT correspondence this amplitude describes the contribution of conserved flavor symmetry currents to 4-point functions of scalar operators in the boundary conformal theory. A concise, covariant, Y2K compatible derivation of the gauge boson propagator in AdS d+ 1 is given. Techniques are developed to calculate the two bulk integrals over AdS space leading to explicit expressions or convenient, simple integral representations for the amplitude. The amplitude contains leading power and sub-leading logarithmic singularities in the gauge boson channel and leading logarithms in the crossed channel. The new methods of this paper are expected to have other applications in the study of the Maldacena conjecture

Lovelock action with nonsmooth boundaries

Science.gov (United States)

Cano, Pablo A.

2018-05-01

We examine the variational problem in Lovelock gravity when the boundary contains timelike and spacelike segments nonsmoothly glued. We show that two kinds of contributions have to be added to the action. The first one is associated with the presence of a boundary in every segment and it depends on intrinsic and extrinsic curvatures. We can think of this contribution as adding a total derivative to the usual surface term of Lovelock gravity. The second one appears in every joint between two segments and it involves the integral along the joint of the Jacobson-Myers entropy density weighted by the Lorentz boost parameter, which relates the orthonormal frames in each segment. We argue that this term can be straightforwardly extended to the case of joints involving null boundaries. As an application, we compute the contribution of these terms to the complexity of global anti-de Sitter space in Lovelock gravity by using the "complexity =action " proposal and we identify possible universal terms for arbitrary values of the Lovelock couplings. We find that they depend on the charge a* controlling the holographic entanglement entropy and on a new constant that we characterize.

We demonstrate how to compute real-time Green's functions for a class of finite temperature field theories from their AdS gravity duals. In particular, we reproduce the two-by-two Schwinger-Keldysh matrix propagator from a gravity calculation. Our methods should work also for computing higher point lorentzian signature correlators. We elucidate the boundary condition subtleties which hampered previous efforts to build a lorentzian-signature AdS/CFT correspondence. For two-point correlators, our construction is automatically equivalent to the previously formulated prescription for the retarded propagator. (author)

THE EFFECTS OF ANTI-DISCRIMINATION LAWS AND POLICIES ON POLITICAL AND ECONOMIC STABILITY OF EUROPEAN UNION

2012-04-01

Full Text Available Development of a civil society and social systems for protection of different groups is directly related to well functioning political and economic systems. If the level of economic development or political stability is not continuous the implementation of antidiscrimination laws would most likely be at a very low level. In this case development of social rights along with implementation of antidiscrimination rights may be marginalized due to three factors: lack of cooperation among political and economic spheres, lack of knowledge about antidiscrimination laws and absence of political will for adoption and implementation of antidiscrimination laws. Therefore, we focus on the examination of specific issues concerning the three aforementioned factors primarily focusing on EU and divergence in the level of political and economic development among the member states.We will argue that antidiscrimination laws are not welcome in new member states, especially since they increase political and economic costs for the governments of respective countries. Level of political development has much to do with the acceptance and inclusion of AD laws in the decision making process. Economic development has much to do with social and living standards within a country which is directly related to the general perception of the population on AD laws. Therefore, one could say that implementation of AD laws heavily depends on the preparedness of people, economic and political system and their will to cope with costs and benefits of implementing those laws.

Revisiting van der Waals like behavior of f(R AdS black holes via the two point correlation function

2017-05-01

Full Text Available Van der Waals like behavior of f(R AdS black holes is revisited via two point correlation function, which is dual to the geodesic length in the bulk. The equation of motion constrained by the boundary condition is solved numerically and both the effect of boundary region size and f(R gravity are probed. Moreover, an analogous specific heat related to δL is introduced. It is shown that the T−δL graphs of f(R AdS black holes exhibit reverse van der Waals like behavior just as the T−S graphs do. Free energy analysis is carried out to determine the first order phase transition temperature T⁎ and the unstable branch in T−δL curve is removed by a bar T=T⁎. It is shown that the first order phase transition temperature is the same at least to the order of 10−10 for different choices of the parameter b although the values of free energy vary with b. Our result further supports the former finding that charged f(R AdS black holes behave much like RN-AdS black holes. We also check the analogous equal area law numerically and find that the relative errors for both the cases θ0=0.1 and θ0=0.2 are small enough. The fitting functions between log⁡|T−Tc| and log⁡|δL−δLc| for both cases are also obtained. It is shown that the slope is around 3, implying that the critical exponent is about 2/3. This result is in accordance with those in former literatures of specific heat related to the thermal entropy or entanglement entropy.

Political institutions of electricity regulation: The case of Turkey

International Nuclear Information System (INIS)

Mustafa Durakoglu, S.

2011-01-01

Turkey has been going through a liberalization process in its electricity market over the last decade. So far, the regulatory content of the market reforms has been in the center of attention in the literature, to the negligence of regulatory governance. However, recent studies, which applied the theoretical insights of new institutional economics to utilities regulation, have demonstrated that political endowments of the country draw the boundaries to which extent such regulatory content can be effectively implemented. In line with these studies, this paper adopts an institutional approach and attempts to identify the political endowments of Turkey in order to further analyze whether the market reforms succeeded in bringing about sufficient checks to cure the institutional problems. In other words, the paper takes a picture of the overall regulatory arena. The results show that the current regulatory structure, especially government-regulator relations, yet fails to meet good regulatory governance criteria. The paper also provides some policy suggestions. - Highlights: → Regulatory governance matters as much as regulatory content. → Political institutions draw boundaries to the implementation of regulatory content. → Market reforms have been insufficient to bring about a true institutional change. → Institutional checks must be devised to limit government interference to the market.

How Internal Political Efficacy Translates Political Knowledge Into Political Participation

Science.gov (United States)

Reichert, Frank

2016-01-01

This study presents evidence for the mediation effect of political knowledge through political self-efficacy (i.e. internal political efficacy) in the prediction of political participation. It employs an action theoretic approach—by and large grounded on the Theory of Planned Behaviour—and uses data from the German Longitudinal Election Study to examine whether political knowledge has distinct direct effects on voting, conventional, and/or unconventional political participation. It argues that political knowledge raises internal political efficacy and thereby indirectly increases the chance that a citizen will participate in politics. The results of mediated multiple regression analyses yield evidence that political knowledge indeed translates into internal political efficacy, thus it affects political participation of various kinds indirectly. However, internal political efficacy and intentions to participate politically yield simultaneous direct effects only on conventional political participation. Sequentially mediated effects appear for voting and conventional political participation, with political knowledge being mediated by internal political efficacy and subsequently also by behavioural intentions. The mediation patterns for unconventional political participation are less clear though. The discussion accounts for restrictions of this study and points to questions for answer by future research.

Touching the base: heart-warming ads from the 2016 U.S. election moved viewers to partisan tears.

2018-03-07

Some political ads used in the 2016 U.S. election evoked feelings colloquially known as being moved to tears. We conceptualise this phenomenon as a positive social emotion that appraises and motivates communal relations, is accompanied by physical sensations (including lachrymation, piloerection, chest warmth), and often labelled metaphorically. We surveyed U.S. voters in the fortnight before the 2016 U.S. election. Selected ads evoked the emotion completely and reliably, but in a partisan fashion: Clinton voters were moved to tears by three selected Clinton ads, and Trump voters were moved to tears by two Trump ads. Viewers were much less moved by ads of the candidate they did not support. Being moved to tears predicted intention to vote for the candidate depicted. We conclude that some contemporary political advertising is able to move its audience to tears, and thereby motivates support.

The Digital Dimension of European Cultural Politics: Index, Intellectual Property and Internet Governance

2011-10-01

Full Text Available The Internet and the World Wide Web (WWW have become dominant fields for European Union (EU politics. What used to be at the outer fringes of the EU policies has now taken centre stage. The transnational and dialogical structure of the Internet has hardwired it for international cultural politics, yet the very same structure also works to erode the very territorial foundation of traditional cultural politics. Given the delicate and complex terrain cultural politics traverse in international politics, and the trailblazing progression of the Internet, it seems on-line cultural politics is not just the application of existing cultural politics to cyberspace but a new field to be explored, analyzed and taught. The present article maps a constituent European cultural boundary on the WWW as the EU has circumscribed it and places this cultural node within a wider array of Europeanization and globalization processes.

Holographic quantum error-correcting codes: toy models for the bulk/boundary correspondence

We propose a family of exactly solvable toy models for the AdS/CFT correspondence based on a novel construction of quantum error-correcting codes with a tensor network structure. Our building block is a special type of tensor with maximal entanglement along any bipartition, which gives rise to an isometry from the bulk Hilbert space to the boundary Hilbert space. The entire tensor network is an encoder for a quantum error-correcting code, where the bulk and boundary degrees of freedom may be identified as logical and physical degrees of freedom respectively. These models capture key features of entanglement in the AdS/CFT correspondence; in particular, the Ryu-Takayanagi formula and the negativity of tripartite information are obeyed exactly in many cases. That bulk logical operators can be represented on multiple boundary regions mimics the Rindler-wedge reconstruction of boundary operators from bulk operators, realizing explicitly the quantum error-correcting features of AdS/CFT recently proposed in http://dx.doi.org/10.1007/JHEP04(2015)163.

In this paper, we shall analyze a three dimensional supersymmetry theory with N = 2 supersymmetry. We will analyze the quantization of this theory, in the presence of a boundary. The effective Lagrangian used in the path integral quantization of this theory, will be given by the sum of the gauge fixing term and the ghost term with the original classical Lagrangian. Even though the supersymmetry of this effective Lagrangian will also be broken due to the presence of a boundary, it will be demonstrated that half of the supersymmetry of this theory can be preserved by adding a boundary Lagrangian to the effective bulk Lagrangian. The supersymmetric transformation of this new boundary Lagrangian will exactly cancel the boundary term generated from the supersymmetric transformation of the effective bulk Lagrangian. We will analyze the Slavnov-Taylor identity for this N = 2 Yang-Mills theory with a boundary. (orig.)

Full Text Available Military-political issues is an important area of research work at MGIMO. The difference in this direction from the classical international specialization is that it is at the intersection of several disciplines: military science, military-technical and military-industrial as well as International Relations. A specialist in military and political issues should not only be an expert in the field of international relations and diplomacy, but also have a deep knowledge of military-technical issues to understand the basic trends in the development of scientific and technological progress and its impact on the balance of forces in the world. Global changes in the balance of power and the nature of the conflict, the emergence of new types of weapons are changing the basic methods and approaches to the art of war, which requires a science-based perspective on problem solving and multi-disciplinary approach in achieving the goals. Military and political studies allow us to understand how the development of military technology and military organization of the state affected by the political situation in the world, the national security of the country and its place in the system of international relations. Military-political research has been developing at MGIMO for a few decades. It laid down the basis for a scientific school of political-military studies. Its founding fathers were such prominent scholars of international affairs, as I.G. Usachyov, A.D. Nikonov, A.G. Arbatov, V.G. Baranovsky, V.M. Kulagin, A.N. Nikitin and other well-known experts. Their work covers a wide range of military and political issues, including the topics of arms control and disarmament, international, and especially European security, military policy, NATO, the Western military-political doctrines and their practical application. Now the lead in the development of this research at MGIMO has taken Center for Military-Political Studies, which became a concentration of relevant

Pre-potential in the AdS{sub 5}×S{sup 5} type IIB superspace

We found the pre-potential in the superspace with AdS{sub 5} × S{sup 5} background. The pre-potential appears as part of the vielbeins, without derivatives. In both subspaces (AdS{sub 5} and S{sup 5}) we used Poincaré coordinates. We picked one bulk coordinate in AdS{sub 5} and one bulk coordinate in S{sup 5} to define the space-cone gauge. Such space-cone gauge destroys the bulk Lorentz covariance. However, it still preserves boundary Lorentz covariance (and gives projective superspace) SO(3,1)⊗SO(4) and so symmetries of boundary CFT are manifest.

Boost-invariant early time dynamics from AdS/CFT

International Nuclear Information System (INIS)

Beuf, Guillaume; Peschanski, Robi; Heller, Michal P.; Janik, Romuald A.

2009-01-01

Boost-invariant dynamics of a strongly-coupled conformal plasma is studied in the regime of early proper-time using the AdS/CFT correspondence. It is shown, in contrast with the late-time expansion, that a scaling solution does not exist. The boundary dynamics in this regime depends on initial conditions encoded in the bulk behavior of a Fefferman-Graham metric coefficient at initial proper-time. The relation between the early-time expansion of the energy density and initial conditions in the bulk of AdS is provided. As a general result it is proven that a singularity of some metric coefficient in Fefferman-Graham frame exists at all times. Requiring that this singularity at τ = 0 is a mere coordinate singularity without the curvature blow-up gives constraints on the possible boundary dynamics. Using a simple Pade resummation for solutions satisfying the regularity constraint, the features of a transition to local equilibrium, and thus to the hydrodynamical late-time regime, have been observed. The impact of this study on the problem of thermalization is discussed.

Boundary causality versus hyperbolicity for spherical black holes in Gauss–Bonnet gravity

International Nuclear Information System (INIS)

Andrade, Tomás; Cáceres, Elena; Keeler, Cynthia

2017-01-01

We explore the constraints boundary causality places on the allowable Gauss–Bonnet gravitational couplings in asymptotically AdS spaces, specifically considering spherical black hole solutions. We additionally consider the hyperbolicity properties of these solutions, positing that hyperbolicity-violating solutions are sick solutions whose causality properties provide no information about the theory they reside in. For both signs of the Gauss–Bonnet coupling, spherical black holes violate boundary causality at smaller absolute values of the coupling than planar black holes do. For negative coupling, as we tune the Gauss–Bonnet coupling away from zero, both spherical and planar black holes violate hyperbolicity before they violate boundary causality. For positive coupling, the only hyperbolicity-respecting spherical black holes which violate boundary causality do not do so appreciably far from the planar bound. Consequently, eliminating hyperbolicity-violating solutions means the bound on Gauss–Bonnet couplings from the boundary causality of spherical black holes is no tighter than that from planar black holes.

We investigate classical strings defined by the Nambu-Goto action with the boundary term added. We demonstrate that the latter term has a significant bearing on the string dynamics. It is confirmed that new action terms that depend on higher order derivatives of string coordinates cannot be considered as continuous perturbations from the starting string functional. In the case the boundary term reduces to the Gauss-Bonnet term, a stability analysis is performed on the rotating rigid string so...

Multi-trace deformations in AdS/CFT. Exploring the vacuum structure of the deformed CFT

We present a general and systematic treatment of multi-trace deformations in the AdS/CFT correspondence in the large N limit, pointing out and clarifying subtleties relating to the formulation of the boundary value problem on a conformal boundary. We then apply this method to study multi-trace deformations in the presence of a scalar VEV, which requires the coupling to gravity to be taken into account. We show that supergravity solutions subject to 'mixed' boundary conditions are in one-to-one correspondence with critical points of the holographic effective action of the dual theory in the presence of a multi-trace deformation, and we find a number of new exact analytic solutions involving a minimally or conformally coupled scalar field satisfying 'mixed' boundary conditions. These include the generalization to any dimension of the instanton solution recently found in hep-th/0611315. Finally, we provide a systematic method for computing the holographic effective action in the presence of a multi-trace deformation in a derivative expansion away from the conformal vacuum using Hamilton-Jacobi theory. Requiring that this effective action exists and is bounded from below reproduces recent results on the stability of the AdS vacuum in the presence of 'mixed' boundary conditions. (orig.)

Assessing Political Dynamics in Contemporary Malaysia: Implications for Democratic Change

Directory of Open Access Journals (Sweden)

2012-01-01

Full Text Available This article examines political dynamics in Malaysia and assesses the prospects for change in the direction of greater political liberalization. It focuses on the 12th General Election of 2008 and its implications for opportunities and challenges for liberal democratic change in Malaysia. It discusses the role of the internet-based new media in shaping an emerging public sphere, and some factors affecting the changing role of non-Malay voters in the political process. This article argues that democratization in Malaysia is already occurring, albeit at a gradual pace; it is being pushed by the new political forces of civil society actors, newly empowered opposition parties, and the internet-based media. The boundaries of this emerging democratic space is simultaneously being shaped and contested by the political competition between status-quo and reformist forces in this society. Some institutional changes have expanded the parameters of democratic space, although the entrenched dominant institutions of the ruling regime continue to wield sufficient amounts of institutional capacity to subvert any consolidation of these democratic changes for now.

Political Ideology, Confidence in Science, and Participation in Alzheimer Disease Research Studies.

Americans' confidence in science varies based on their political ideology. This ideological divide has potentially important effects on citizens' engagement with and participation in clinical studies of Alzheimer disease (AD). A probability sample of 1583 Americans was surveyed about their willingness to participate in longitudinal AD research and about their political attitudes. These survey results were compared with a survey of 382 participants in a longitudinal AD study at the Knight Alzheimer Disease Research Center. Among Americans, more conservative ideology decreases willingness to participate in a hypothetical longitudinal cohort study of AD both directly and through its negative effect on confidence in science. The Knight Alzheimer Disease Research Center study participants expressed more liberal ideology and greater confidence in science than Americans in general. Of the survey respondents opposed to participation, over a quarter changed to neutral or positive if the study returned their research results to them. Clinical studies of AD are likely biased toward participants who are more liberal and have higher confidence in science than the general population. This recruitment bias may be reduced by lowering the trust demanded of participants through measures such as returning research results to participants.

Hairy black hole stability in AdS, quantum mechanics on the half-line and holography

We consider the linear stability of 4-dimensional hairy black holes with mixed boundary conditions in Anti-de Sitter spacetime. We focus on the mass of scalar fields around the maximally supersymmetric vacuum of the gauged N=8 supergravity in four dimensions, m"2=−2l"−"2. It is shown that the Schrödinger operator on the half-line, governing the S"2, H"2 or ℝ"2 invariant mode around the hairy black hole, allows for non-trivial self-adjoint extensions and each of them corresponds to a class of mixed boundary conditions in the gravitational theory. Discarding the self-adjoint extensions with a negative mode impose a restriction on these boundary conditions. The restriction is given in terms of an integral of the potential in the Schrödinger operator resembling the estimate of Simon for Schrödinger operators on the real line. In the context of AdS/CFT duality, our result has a natural interpretation in terms of the field theory dual effective potential.

RG flow and thermodynamics of causal horizons in higher-derivative AdS gravity

International Nuclear Information System (INIS)

Banerjee, Shamik; Bhattacharyya, Arpan

2016-01-01

In http://arxiv.org/abs/1508.01343 [hep-th], one of the authors proposed that in AdS/CFT the gravity dual of the boundary c-theorem is the second law of thermodynamics satisfied by causal horizons in AdS and this was verified for Einstein gravity in the bulk. In this paper we verify this for higher derivative theories. We pick up theories for which an entropy expression satisfying the second law exists and show that the entropy density evaluated on the causal horizon in a RG flow geometry is a holographic c-function. We also prove that given a theory of gravity described by a local covariant action in the bulk a sufficient condition to ensure holographic c-theorem is that the second law of causal horizon thermodynamics be satisfied by the theory. This allows us to explicitly construct holographic c-function in a theory where there is curvature coupling between gravity and matter and standard null energy condition cannot be defined although second law is known to hold. Based on the duality between c-theorem and the second law of causal horizon thermodynamics proposed in http://arxiv.org/abs/1508.01343 [hep-th] and the supporting calculations of this paper we conjecture that every Unitary higher derivative theory of gravity in AdS satisfies the second law of causal horizon thermodynamics. If this is not true then c-theorem will be violated in a unitary Lorentz invariant field theory.

Weak field black hole formation in asymptotically AdS spacetimes

International Nuclear Information System (INIS)

Bhattacharyya, Sayantani; Minwalla, Shiraz

2009-01-01

We use the AdS/CFT correspondence to study the thermalization of a strongly coupled conformal field theory that is forced out of its vacuum by a source that couples to a marginal operator. The source is taken to be of small amplitude and finite duration, but is otherwise an arbitrary function of time. When the field theory lives on R d-1,1 , the source sets up a translationally invariant wave in the dual gravitational description. This wave propagates radially inwards in AdS d+1 space and collapses to form a black brane. Outside its horizon the bulk spacetime for this collapse process may systematically be constructed in an expansion in the amplitude of the source function, and takes the Vaidya form at leading order in the source amplitude. This solution is dual to a remarkably rapid and intriguingly scale dependent thermalization process in the field theory. When the field theory lives on a sphere the resultant wave either slowly scatters into a thermal gas (dual to a glueball type phase in the boundary theory) or rapidly collapses into a black hole (dual to a plasma type phase in the field theory) depending on the time scale and amplitude of the source function. The transition between these two behaviors is sharp and can be tuned to the Choptuik scaling solution in R d,1 .

We show that the Skenderis-van Rees prescription and the “extrapolate” dictionary are equivalent at the level of “in-in” two point functions of free scalar fields in arbitrary asymptotically AdS spacetimes. In the second part of the paper, we calculate two point correlation functions in dynamical spacetimes using the “extrapolate” dictionary. These calculations are performed for conformally coupled scalar fields in examples of spacetimes undergoing gravitational collapse, the AdS 2 -Vaidya spacetime and the AdS 3 -Vaidya spacetime, which allow us to address the problem of thermalization following a quench in the boundary field theory. The computation of the correlators is formulated as an initial value problem in the bulk spacetime. Finally, we compare our results for AdS 3 -Vaidya to results in the previous literature obtained using the geodesic approximation and we find qualitative agreement.

On modular properties of the AdS3 CFT

International Nuclear Information System (INIS)

Baron, Walter H.; Nunez, Carmen A.

2011-01-01

We study modular properties of the AdS 3 Wess-Zumino-Novikov-Witten model. Although the Euclidean partition function is modular invariant, the characters on the Euclidean torus diverge and the regularization proposed in the literature removes information on the spectrum and the usual one to one map between characters and representations of rational models is lost. Reconsidering the characters defined on the Lorentzian torus and focusing on their structure as distributions, we obtain expressions that recover those properties. We study their modular transformations and find a generalized S matrix, depending on the sign of the real modular parameters, which has two diagonal blocks and one off-diagonal block, mixing discrete and continuous representations, that we fully determine. We then explore the relations among the modular transformations, the fusion algebra and the boundary states. We explicitly construct Ishibashi states for the maximally symmetric D-branes and show that the generalized S matrix defines the one-point functions associated to pointlike and H 2 -branes as well as the fusion rules of the degenerate representations of sl(2,R) appearing in the open string spectrum of the pointlike D-branes, through a generalized Verlinde theorem.

On the AdS higher spin / O(N) vector model correspondence: degeneracy of the holographic image

International Nuclear Information System (INIS)

Diaz, Danilo E.; Dorn, Harald

2006-01-01

We explore the conjectured duality between the critical O(N) vector model and minimal bosonic massless higher spin (HS) theory in AdS. In the free boundary theory, the conformal partial wave expansion (CPWE) of the four-point function of the scalar singlet bilinear is reorganized to make it explicitly crossing-symmetric and closed in the singlet sector, dual to the bulk HS gauge fields. We are able to analytically establish the factorized form of the fusion coefficients as well as the two-point function coefficient of the HS currents. We insist in directly computing the free correlators from bulk graphs with the unconventional branch. The three-point function of the scalar bilinear turns out to be an 'extremal' one at d = 3. The four-point bulk exchange graph can be precisely related to the CPWs of the boundary dual scalar and its shadow. The flow in the IR by Legendre transforming at leading 1/N, following the pattern of double-trace deformations, and the assumption of degeneracy of the hologram lead to the CPWE of the scalar four-point function at IR. Here we confirm some previous results, obtained from more involved computations of skeleton graphs, as well as extend some of them from d = 3 to generic dimension 2 < d < 4

Static elliptic minimal surfaces in AdS{sub 4}

Energy Technology Data Exchange (ETDEWEB)

Pastras, Georgios [NCSR ' ' Demokritos' ' , Institute of Nuclear and Particle Physics, Attiki (Greece)

2017-11-15

The Ryu-Takayanagi conjecture connects the entanglement entropy in the boundary CFT to the area of open co-dimension two minimal surfaces in the bulk. Especially in AdS{sub 4}, the latter are two-dimensional surfaces, and, thus, solutions of a Euclidean non-linear sigma model on a symmetric target space that can be reduced to an integrable system via Pohlmeyer reduction. In this work, we construct static minimal surfaces in AdS{sub 4} that correspond to elliptic solutions of the reduced system, namely the cosh-Gordon equation, via the inversion of Pohlmeyer reduction. The constructed minimal surfaces comprise a two-parameter family of surfaces that include helicoids and catenoids in H{sup 3} as special limits. Minimal surfaces that correspond to identical boundary conditions are discovered within the constructed family of surfaces and the relevant geometric phase transitions are studied. (orig.)

We study a mass splitting of the light vector, axial-vector, and pseudoscalar mesons in the isospin medium in the framework of the hard-wall model. We write an effective mass definition for the interacting gauge fields and scalar field introduced in gauge field theory in the bulk of AdS space-time. Relying on holographic duality we obtain a formula for the effective mass of a boundary meson in terms of derivative operator over the extra bulk coordinate. The effective mass found in this way coincides with the one obtained from finding of poles of the two-point correlation function. In order to avoid introducing distinguished infrared boundaries in the quantization formula for the different mesons from the same isotriplet we introduce extra action terms at this boundary, which reduces distinguished values of this boundary to the same value. Profile function solutions and effective mass expressions were found for the in-medium ρ, a{sub 1}, an π mesons. (orig.)

AdS/CFT correspondence, quasinormal modes, and thermal correlators in N=4 SYM

We use the Lorentzian AdS/CFT prescription to find the poles of the retarded thermal Green's functions of ${\\cal N=4}$ SU(N) SYM theory in the limit of large N and large 't Hooft coupling. In the process, we propose a natural definition for quasinormal modes in an asymptotically AdS spacetime, with boundary conditions dictated by the AdS/CFT correspondence. The corresponding frequencies determine the dispersion laws for the quasiparticle excitations in the dual finite-temperature gauge theory...

Mosquito politics: local vector control policies and the spread of West Nile Virus in the Chicago region.

Science.gov (United States)

Tedesco, Carmen; Ruiz, Marilyn; McLafferty, Sara

2010-11-01

Differences in mosquito control practices at the local level involve the interplay of place, scale and politics. During the Chicago West Nile Virus (WNV) outbreak of 2002, mosquito abatement districts represent distinct suburban clusters of human WNV cases, independent of characteristics of the local population, housing and physical environment. We examine how the contrasting actions of four districts reveal a distinct local politics of mosquito control that may have contributed to local-scale geographic differences in WNV incidence. This politics is rooted in political, economic and philosophical differences within and between administrative boundaries. Copyright © 2010 Elsevier Ltd. All rights reserved.

The politics of health sector reform in developing countries: three cases of pharmaceutical policy.

Science.gov (United States)

Reich, M R

1995-01-01

This paper examines the political dynamics of health sector reform in poor countries, through a comparative study of pharmaceutical policy reform in Sri Lanka, Bangladesh, and the Philippines. The paper first reviews five reasons why policy reform is political. It then presents three political economic models of the policy reform process: the political will, political factions, and political survival models. Next, the paper describes the three cases of national pharmaceutical policy reform, and identifies common conditions that made these reforms politically feasible. The paper's analysis suggests that health sector reform is feasible at certain definable, and perhaps predictable, political moments, especially in the early periods of new regimes. The most important and manipulable political factors are: political timing, which provides opportunities for policy entrepreneurs to introduce their ideas into public debate, and political management of group competition, which allows leaders to control the political effects of distributional consequences and protect the regime's stability. A strong and narrow political coalition improves the capacity of political leaders to resist the pressures of concentrated economic costs (both inside and outside national boundaries). The paper argues that for reform to succeed, policy-makers need effective methods to analyze relevant political conditions and shape key political factors in favor of policy reform. The method of Political Mapping is briefly introduced as a technique that can help policy-makers in analyzing and managing the political dimensions of policy reform and in improving the political feasibility of reform.

Boundary work of dentists in everyday work.

Science.gov (United States)

Franzén, Cecilia

2012-08-01

The Swedish policy objectives in dental care provision - to meet public demands for dental care and to increase the cost-effectiveness of the service - require dentists to work in teams with dental hygienists and dental nurses. This study focused on the role of dentists in the distribution of work tasks within teams in one Swedish Public Dental Service organisation. Dental clinics were viewed as micro-political arenas in which dentists attempt to demarcate professional boundaries in response to teamwork. Semi-structured interviews, observations and documents were used. The interviewed individuals were seven dentists employed at two clinics, the managers of each clinic and the general manager. The dentists were interviewed to investigate how they defend or blur professional boundaries. They were also observed at work. The clinic managers and the general manager were interviewed to identify their expectations of dentists concerning work division. The documents comprised organisational plans and annual reports. Dentists demarcated professional boundaries by utilising various power resources: treatment responsibility, specialist knowledge, discretion, and avoidance of work considered to be low status work. The dentists also contributed to blurred boundaries between themselves and the other dental professionals by discussing patient treatment, giving and receiving advice, and assisting the others in skill development. Although dentists' boundary work could obstruct implementation of policy objectives, dentists' behaviour contributed to effective collaboration within the teams. © 2012 John Wiley & Sons A/S.

Recursion relations for AdS/CFT correlators

International Nuclear Information System (INIS)

Raju, Suvrat

2011-01-01

We expand on the results of our recent letter [Phys. Rev. Lett. 106, 091601 (2011)], where we presented new recursion relations for correlation functions of the stress-tensor and conserved currents in conformal field theories with an AdS d+1 dual for d≥4. These recursion relations are derived by generalizing the Britto-Cachazo-Feng-Witten (BCFW) relations to amplitudes in anti-de Sitter space (AdS) that are dual to boundary correlators, and are usually computed perturbatively by Witten diagrams. Our results relate vacuum-correlation functions to integrated products of lower-point transition amplitudes, which correspond to correlators calculated between states dual to certain normalizable modes. We show that the set of ''polarization vectors'' for which amplitudes behave well under the BCFW extension is smaller than in flat-space. We describe how transition amplitudes for more general external polarizations can be constructed by combining answers obtained by different pairs of BCFW shifts. We then generalize these recursion relations to supersymmetric theories. In AdS, unlike flat-space, even maximal supersymmetry is insufficient to permit the computation of all correlators of operators in the same multiplet as a stress-tensor or conserved current. Finally, we work out some simple examples to verify our results.

Large N elliptic genus and AdS/CFT Correspondence

Boer, Jan de

1998-01-01

According to one of Maldacena's dualities, type IIB string theory on AdS 3 x S 3 x K3 is equivalent to a certain N = (4, 4) superconformal field theory. In this note we compute the elliptic genus of the boundary theory in the supergravity approximation. A finite quantity is obtained once we introduce a particular exclusion principle. In the regime where the supergravity approximation is reliable, we find exact agreement with the elliptic genus of a sigma model with target space K3 N /S N

We present new supersymmetric AdS 3 solutions of type IIB supergravity and AdS 2 solutions of D = 11 supergravity. The former are dual to conformal field theories in two dimensions with N = (0, 2) supersymmetry while the latter are dual to conformal quantum mechanics with two supercharges. Our construction also includes AdS 2 solutions of D = 11 supergravity that have non-compact internal spaces which are dual to three-dimensional N = 2 superconformal field theories coupled to point-like defects. We also present some new bubble-type solutions, corresponding to BPS states in conformal theories, that preserve four supersymmetries

On AdS/CFT correspondence beyond SUGRA: plane waves, free CFTs and double-trace deformations

Energy Technology Data Exchange (ETDEWEB)

Diaz Vazquez, D.E.

2007-09-13

This thesis deals with three corners of the AdS/CFT Correspondence that lie one step beyond the classical supergravity (SUGRA) approximation. We first explore the BMN limit of the duality and study, in particular, the behavior of field theoretic propagators in the corresponding Penrose limit. We unravel the semiclassical (WKB-) exactness of the propagators in the resulting plane wave background metric. Then, we address the limit of vanishing coupling of the conformal field theory (CFT) at large N. In the simplified scenario of Higher Spin/O(N) Vector Model duality, the conformal partial wave (CPW) expansion of scalar four-point functions are reorganized to make them suggestive of a bulk interpretation in term of a consistent truncated massless higher spin theory and their corresponding exchange Witten graphs. We also explore the connection to the interacting O(N) Vector Model at its infra-red fixed point, at leading large N. Finally, coming back to the gauge theory, we study the effect of a relevant double-trace deformations of the boundary CFT on the partition function and its dual bulk interpretation. We show how the one-loop computation in the Anti-de Sitter (AdS) space correctly reproduces the partition function and conformal anomaly of the boundary theory. In all, we get a clean test of the duality beyond the classical SUGRA approximation in the AdS bulk and at the corresponding next-to-leading 1/N order of the CFT at the conformal boundary. (orig.)

Nursing's Boundary Work: Theory Development and the Making of Nursing Science, ca. 1950-1980.

Science.gov (United States)

Tobbell, Dominique A

Beginning in the late 1950s and intensifying through the 1960s and 1970s, nurse educators, researchers, and scholars worked to establish nursing as an academic discipline. These nursing leaders argued that the development of nursing theory was not only critical to nursing's academic project but also to improving nursing practice and patient care. The purpose of the article is to examine the context for the development of nursing theory and the characteristics of early theory development from the 1950s through the early 1980s. The methods used were historical research and analysis of the social, cultural, and political context of nursing theory development from the 1950s through the early 1980s. How this context influenced the work of nurse theorists and researchers in these decades was addressed. The development of nursing theory was influenced by a context that included the increasing complexity of patient care, the relocation of nursing education from hospital-based diploma schools to colleges and universities, and the ongoing efforts of nurses to secure more professional autonomy and authority in the decades after World War II. In particular, from the 1960s through the early 1980s, nurse theorists, researchers, and educators viewed the establishment of nursing science, underpinned by nursing theory, as critical to establishing nursing as an academic discipline. To define nursing science, nurse theorists and researchers engaged in critical boundary work in order to draw epistemic boundaries between nursing science and the existing biomedical and behavioral sciences. By the early 1980s, the boundary work of nurse theorists and researchers was incomplete. Their efforts to define nursing science and establish nursing as an academic discipline were constrained by generational and intraprofessional politics, limited resources, the gendered and hierarchical politics, and the complexity of drawing disciplinary boundaries for a discipline that is inherently

The Digital Political Communication of South Korean Politicians

Heike Hermanns

2017-12-01

Full Text Available The internet and social media have been credited with the potential to reinvigorate democracy by offering new avenues of political participation and communication between citi-zens and politicians. The results of empirical studies, however, call for caution, as many politi-cians refrain from fully exploring the interactive potential of new media. This case study focus-es on the web presence of Korean parliamentarians, using basic statistical analyses to explore the use of ICT as a means of political communication. It finds that Korean parliamentarians are less active online, treating ICT mainly as another channel for information distribution. It is thus concluded that ICT is not revolutionizing politics but reinforcing existing patterns of communi-cation that leave a gap between citizens and representatives. This paper was previously submit-ted to CeDem Asia 2016. The literature review and the methodology section have been expand-ed, and additional statistical data as well as further findings on Twitter were added.

Throat quantization of the Schwarzschild–Tangherlini(-AdS) black hole

International Nuclear Information System (INIS)

Kunstatter, Gabor; Maeda, Hideki

2014-01-01

Adopting the throat quantization pioneered by Louko and Mäkelä, we derive the mass and area spectra for the Schwarzschild–Tangherlini black hole and its anti-de Sitter (AdS) generalization in arbitrary dimensions. We find that the system can be quantized exactly in three special cases: the three-dimensional BTZ black hole, toroidal black holes in any dimension, and five-dimensional Schwarzshild–Tangherlini(-AdS) black holes. For the remaining cases the spectra are obtained for large mass using the WKB approximation. For asymptotically flat black holes, the area/entropy has an equally spaced spectrum, as expected from previous work. In the asymptotically AdS case on the other hand, it is the mass spectrum that is equally spaced. Our exact results for the BTZ black hole mass with Dirichlet boundary conditions are consistent with the spectra of the corresponding operators in the dual CFT. (paper)

Bias in the Flesh: Skin Complexion and Stereotype Consistency in Political Campaigns.

Science.gov (United States)

Messing, Solomon; Jabon, Maria; Plaut, Ethan

2016-01-01

There is strong evidence linking skin complexion to negative stereotypes and adverse real-world outcomes. We extend these findings to political ad campaigns, in which skin complexion can be easily manipulated in ways that are difficult to detect. Devising a method to measure how dark a candidate appears in an image, this paper examines how complexion varied with ad content during the 2008 presidential election campaign (study 1). Findings show that darker images were more frequent in negative ads-especially those linking Obama to crime-which aired more frequently as Election Day approached. We then conduct an experiment to document how these darker images can activate stereotypes, and show that a subtle darkness manipulation is sufficient to activate the most negative stereotypes about Blacks-even when the candidate is a famous counter-stereotypical exemplar-Barack Obama (study 2). Further evidence of an evaluative penalty for darker skin comes from an observational study measuring affective responses to depictions of Obama with varying skin complexion, presented via the Affect Misattribution Procedure in the 2008 American National Election Study (study 3). This study demonstrates that darker images are used in a way that complements ad content, and shows that doing so can negatively affect how individuals evaluate candidates and think about politics.

Use of geostatistics for remediation planning to transcend urban political boundaries

International Nuclear Information System (INIS)

Milillo, Tammy M.; Sinha, Gaurav; Gardella, Joseph A.

2012-01-01

Soil remediation plans are often dictated by areas of jurisdiction or property lines instead of scientific information. This study exemplifies how geostatistically interpolated surfaces can substantially improve remediation planning. Ordinary kriging, ordinary co-kriging, and inverse distance weighting spatial interpolation methods were compared for analyzing surface and sub-surface soil sample data originally collected by the US EPA and researchers at the University at Buffalo in Hickory Woods, an industrial–residential neighborhood in Buffalo, NY, where both lead and arsenic contamination is present. Past clean-up efforts estimated contamination levels from point samples, but parcel and agency jurisdiction boundaries were used to define remediation sites, rather than geostatistical models estimating the spatial behavior of the contaminants in the soil. Residents were understandably dissatisfied with the arbitrariness of the remediation plan. In this study we show how geostatistical mapping and participatory assessment can make soil remediation scientifically defensible, socially acceptable, and economically feasible. - Highlights: ► Point samples and property boundaries do not appropriately determine the extent of soil contamination. ► Kriging and co-kriging provide best concentration estimates for mapping soil contamination and refining clean-up sites. ► Maps provide a visual representation of geostatistical results to communities to aid in geostatistical decision making. ► Incorporating community input into the assessment of neighborhoods is good public policy practice. - Using geostatistical interpolation and mapping results to involve the affected community can substantially improve remediation planning and promote its long-term effectiveness.

Political Transmigrants: Rethinking Hmong Political Activism in America

Directory of Open Access Journals (Sweden)

Nengher N. Vang, Ph.D

2011-12-01

Full Text Available Since the initial resettlement of the Hmong in the United States in the mid-1970s, they have maintained strong political and military relationships with the Lao People‘s Democratic Republic (LPDR. Yet, there is little research on that relationship and the involvement of the Hmong in the United States in political developments in Laos. Most works on Hmong political activism have focused on the electoral participation and representation of Hmong Americans in relation to American domestic politics. In this article, using archival, ethnographic, and interview data that I have collected between 2006 and 2009 in Laos, Thailand, and the United States, I describe and analyze the non-domestic or transnational form of Hmong American political expression and participation. I argue that Hmong political activism in America not only was transnational from the outset, but that their transnational involvement in political developments in Laos and their relations with the Lao PDR government also had a significant impact on their ethnic politics. Many Hmong political activists made their entry into ethnic politics through the door of transnational politics, and many were motivated by transnational political issues to participate in domestic American politics. By exploring their transnational involvement in political developments in Laos and their relations with the Lao PDR government, we get a more complete and dynamic understanding of Hmong political activism in the United States than is possible by focusing exclusively on domestic and electoral participation. Examining their transnational politics also allows us to see the transnationality of not only their culture, identity, and community but also that of their political activities and aspirations.

Vulnerability, gender norms and state violence: social ontology and sexual politics in the last Judith Butler

Directory of Open Access Journals (Sweden)

Eduardo Mattio

2010-12-01

Full Text Available In his recent work, Judith Butler has offered a reconsideration of “the human” that allow re-imagine the boundaries of political community. Underlining the common precariousness that characterizes “the human” and revealing the symbolic and material conditions that politically maximize that situation, Butler gives us useful tools not only to elucidate the selective mechanisms that produce "the human" but also to subvert the normative horizon that determined it. From such assumptions, I understand that one can propose some considerations that permit the design of sexual politics more responsive to the needs of the most precarious groups of LGBT collective.

Social Networks and Political Parties in Chile

Directory of Open Access Journals (Sweden)

Adler Lomnitz, Larissa

2002-09-01

Full Text Available This paper describes the origin and evolution of two Chilean political parties (the Radical Party and the Christian Democrat Party through the analysis of the social networks that originated and composed them. The aim of this study is to propose a model of national political cultures on the basis of the structure of social networks related to power and of the symbol system, which legitimizes it. The structure of social networks, horizontal and vertical, are based on reciprocal or redistributive forms of exchange, on what is being exchanged and on the articulation between networks. In every society there are symmetrical and asymmetrical exchanges, which produce horizontal and vertical networks. These networks interact among themselves to form the social fabric. The dominance of some over others and how they combine, delineate the character of the political culture (authoritarian vs. egalitarian. Chile is a multiparty country within which there are cohorts of horizontal groups of friends, who informally exercise a central control over their members and create invisible boundaries setting them apart from others, in which leadership is under constrains. The result is both a strong presidential system based on an almost fanatic legitimacy, combined with factionalism and a strong parliamentary system.

Boundary spectra in superspace σ-models

International Nuclear Information System (INIS)

Quella, T.; Schomerus, V.; Creutzig, T.

2007-12-01

In this note we compute exact boundary spectra for D-instantons in σ-models on the supergroup PSL(22). Our results are obtained through an explicit summation of the perturbative expansion for conformal dimensions to all orders in the curvature radius. The analysis exploits several remarkable properties of the perturbation series that arises from rescalings of the metric on PSL(22) relative to a fixed Wess- Zumino term. According to Berkovits, Vafa and Witten, the models are relevant in the context of string theory on AdS 3 with non-vanishing RR-flux. The note concludes with a number of comments on various possible generalizations to other supergroups and higher dimensional supercoset theories. (orig.)

Boundary terms in the Nambu-Goto string action

Science.gov (United States)

Hadasz, Leszek; Wȩgrzyn, Paweł

1995-03-01

We investigate classical strings defined by the Nambu-Goto action with the boundary term added. We demonstrate that the latter term has a significant bearing on the string dynamics. It is confirmed that new action terms that depend on higher order derivatives of string coordinates cannot be considered as continuous perturbations from the starting string functional. In the case when the boundary term reduces to the Gauss-Bonnet term, a stability analysis is performed on the rotating rigid string solution. We determine the most generic solution that the fluctuations grow to. Longitudinal string excitations are found. The Regge trajectories are nonlinear.

EVOLUTIONS OF THE OLYMPIC MOVEMENT UNDER THE INFLUENCE OF THE CHANGES ON THE WORLD POLITICAL MAP IN THE INTERWAR PERIOD

Directory of Open Access Journals (Sweden)

Vasile GRAMA

2016-11-01

Full Text Available The use of sports and politics has had both positive and negative implications over history. Sports competitions or activities have had the intention to bring about change in certain cases. Nationalistic fervor is sometimes linked to victories or losses to some sport on sports fields. Also, new independent countries need to be recognized on international arena, so participating at the Olympic Games, they become more visible and marginalization is broken. National feelings are boosted by some of the finest sports performances. The interwar period took politics to the sporting arena; when governments decided to control the sport and politics became more authoritative and states went on to find new ways to dominate the thinking process and imagination of their citizens. Fascist regimes developed techniques that allowed them to use achievements made in sporting arena to inspire people within their geographical boundaries and impress those beyond these boundaries. A fanatic love with sports was developed and through it, symbols of nationalist socialism were entrenched.

Toward the AdS/CFT gravity dual for high energy collisions. III. Gravitationally collapsing shell and quasiequilibrium

International Nuclear Information System (INIS)

Lin, Shu; Shuryak, Edward

2008-01-01

The equilibration of matter and onset of hydrodynamics can be understood in the AdS/CFT context as a gravitational collapse process, in which 'collision debris' create a horizon. In this paper we consider the simplest geometry possible, a flat shell (or membrane) falling in the holographic direction toward the horizon. The metric is a combination of two well-known solutions: thermal AdS above the shell and pure AdS below, while motion of the shell is given by the Israel junction condition. Furthermore, when the shell motion can be considered slow, we were able to solve for two-point functions of all boundary stress tensors and found that an observer on the boundary sees a very peculiar quasiequilibrium: while the average stress tensor μν> contains the equilibrium plasma energy and pressure at all times, the spectral densities of the correlators (related with occupation probabilities of the modes) reveal additional oscillating terms absent in equilibrium. This is explained by the echo phenomenon, a partial return of the field coherence at certain echo times.

Precursors, gauge invariance, and quantum error correction in AdS/CFT

Energy Technology Data Exchange (ETDEWEB)

Freivogel, Ben; Jefferson, Robert A.; Kabir, Laurens [ITFA and GRAPPA, Universiteit van Amsterdam,Science Park 904, Amsterdam (Netherlands)

2016-04-19

A puzzling aspect of the AdS/CFT correspondence is that a single bulk operator can be mapped to multiple different boundary operators, or precursors. By improving upon a recent model of Mintun, Polchinski, and Rosenhaus, we demonstrate explicitly how this ambiguity arises in a simple model of the field theory. In particular, we show how gauge invariance in the boundary theory manifests as a freedom in the smearing function used in the bulk-boundary mapping, and explicitly show how this freedom can be used to localize the precursor in different spatial regions. We also show how the ambiguity can be understood in terms of quantum error correction, by appealing to the entanglement present in the CFT. The concordance of these two approaches suggests that gauge invariance and entanglement in the boundary field theory are intimately connected to the reconstruction of local operators in the dual spacetime.

Islamic Political Thought between Justice Value and the State Structure

Directory of Open Access Journals (Sweden)

Ahmed As-Sirri

2013-06-01

Full Text Available The paper discusses the relationship between state structure and the implementing of justice in the Islamic society. The shift from caliphate system to the system of royal system starting from the Umayyad Dynasty (41-132 AH / 661-750 AD made the issue of social justice highly urgent. The main question discussed was : Is there a relationship between state structure and achieving social justice? To answer this question the paper reviews the relationship between religious authorities and political authorities in the main periods of Islamic history. Based on these relations as well as the intellectual product known as the “Heritage of Islamic Political Thought”, we concluded that the classical structure of Islamic state didn’t assure the implementing of justice. In light of the forgoing idea we could also conclude that the political islamic thought used today in context of “Arab spring” does not support the aspirations of building a modern state that assures the implementing of justice as well as variety of social, cultural and political rights.

An influence of extremal edges on boundary extension.

Science.gov (United States)

Hale, Ralph G; Brown, James M; McDunn, Benjamin A; Siddiqui, Aisha P

2015-08-01

Studies have shown that people consistently remember seeing more of a studied scene than was physically present (e.g., Intraub & Richardson Journal of Experimental Psychology: Learning, Memory, and Cognition, 15, 179-187, 1989). This scene memory error, known as boundary extension, has been suggested to occur due to an observer's failure to differentiate between the contributing sources of information, including the sensory input, amodal continuation beyond the view boundaries, and contextual associations with the main objects and depicted scene locations (Intraub, 2010). Here, "scenes" made of abstract shapes on random-dot backgrounds, previously shown to elicit boundary extension (McDunn, Siddiqui, & Brown Psychonomic Bulletin & Review, 21, 370-375, 2014), were compared with versions made with extremal edges (Palmer & Ghose Psychological Science, 19, 77-84, 2008) added to their borders, in order to examine how boundary extension is influenced when amodal continuation at the borders' view boundaries is manipulated in this way. Extremal edges were expected to reduce boundary extension as compared to the same scenes without them, because extremal edge boundaries explicitly indicate an image's end (i.e., they do not continue past the view boundary). A large and a small difference (16 % and 40 %) between the close and wide-angle views shown during the experiment were tested to examine the effects of both boundary extension and normalization with and without extremal edges. Images without extremal edges elicited typical boundary extension for the 16 % size change condition, whereas the 40 % condition showed signs of normalization. With extremal edges, a reduced amount of boundary extension occurred for the 16 % condition, and only normalization was found for the 40 % condition. Our findings support and highlight the importance of amodal continuation at the view boundaries as a component of boundary extension.

Defects in higher-dimensional quantum field theory. Relations to AdS/CFT-correspondence and Kondo lattices

Energy Technology Data Exchange (ETDEWEB)

Schmidt, R.

2007-03-15

The present work is addressed to defects and boundaries in quantum field theory considering the application to AdS/CFT correspondence. We examine interactions of fermions with spins localised on these boundaries. Therefore, an algebra method is emphasised adding reflection and transmission terms to the canonical quantisation prescription. This method has already been applied to bosons in two space-time dimensions before. We show the possibilities of such reflection-transmission algebras in two, three, and four dimensions. We compare with models of solid state physics as well as with the conformal field theory approach to the Kondo effect. Furthermore, we discuss ansatzes of extensions to lattice structures. (orig.)

Migration of liquid film and grain boundary in Mo-Ni induced by W diffusion

International Nuclear Information System (INIS)

Kang, H.K.; Hackney, S.; Yoon, D.N.

1988-01-01

The liquid films and grain boundaries in liquid phase sintered Mo-Ni alloy are observed to migrate during heat-treatment after adding W to the liquid matrix. Behind the migrating boundaries forms Mo-Ni-W solid solution with the W concentration decreasing with the migration distance because of W depletion in the liquid matrix. The migration rate during the heat-treatment at 1540 0 C after adding W decreases with the decreasing pretreatment sintering temperature. When the sintering temperature is 1420 0 C, the migration rate is almost reduced to O. Under this condition, the coherency strain due to the simultaneous diffusion of W and Ni into the grain surfaces is estimated to be almost O. The results thus show that the coherency strain due to lattice diffusion is the driving force for the liquid film and grain boundary migration

The Nature and Functions of European Political Borders

Directory of Open Access Journals (Sweden)

Full Text Available The political border limits a state’s territory and symbolizes the extent of a state’s power and ownership. Borders give integrity to the inner state territory which they enclose (the role of establishing national integrity and at the same time form an outer boundary segregating the state territory from the surrounding politicial entities (the segregation role. European borders are old and reflect the political history of an old continent. The last major border changes happened after World War II. Over the centuries borders were merely lines separating one territory from another. Such borders were understood as »frontiers«. Forming an effective barrier against enemies was the overriding function of borders. Many borders were fortified and further enhanced by means of various defensive systems. In the second half of the 20th century the character of political borders changed. They became a contact area between countries, nations and cultures. Contemporary European borders reflect the colourful history of an old continent. They are predominantely functional markers: they represent the political and juridical delimitation of territories, they mark economic barriers and show their defensive nature and reveal the extent of cultural contact. As a result of European integration processes, the nature of political borders has changed: instead of division, their integration role is brought to the fore. A united Europe is nevertheless still not a borderless Europe! The borders within the »Schengen-area« have retained their political and administrative functions, it is just that the customs and security checks at the borders have been removed. During the period of European integration, borderlines were stabilized in accordance with the 1974 Helsinki Agreement. But despite this we can still observe ongoing changes to state borders, particularly in areas of conflict such as the Balkan peninsula. It seems after all that the process of demarcation

Paths of Research in Religion and Politics: An Introduction

Directory of Open Access Journals (Sweden)

Alberta Giorgi

2014-03-01

Full Text Available Religion plays an important role in contemporary politics, both as a public and political actor, and as set of values. As a public actor, religion widely participates in the political spheres of European countries. At the same time, both European and non-European societies are experiencing a profound reshaping of their political landscapes. In these contexts, it has become clear that new modes of governance redraw the boundaries between institutional actors and citizens, and create space for horizontal and/or transnational networks. Today, the separation between religion and politics is being questioned more or less radically, and the meaning and the substance of democracy likewise. This special issue aims to offer a wide range of examples of studies focusing on the interactions between religion and politics from different disciplinary perspectives and scientific traditions. Ranging from single case studies to transnational comparative analyses, from sociology of religion to political science, and from the analysis of specific religious traditions to comparative studies, the articles presented offer a useful insight of topics and debates. This heterogeneity allows the readers to have an overview on some of the most important religious actors (movements, associations, groups and, parties in contemporary democracies, such as Christian traditional parties in Europe and the US, Islamist groups in Turkey and in Pakistan. At the same time, this collection of article shows different approaches through which is possible to analyse these movements, such as cross-country comparative approaches, comparison between different cases of religious groups’ collective action within the same national contexts or in the same urban area, or in-depth case studies of the specific role of religious groups in a broader national mobilization. The common element of these different contributions is the objective of looking at the complex relationships between religious

It examines theological and political aspects of such influence and its consequences for the region. The author analyses origins of the transnational Shia movements such as “Harakat ar-Risala” and “ad-Dawa” linked with traditional Shia institutions at Najaf and Kerbela, and its ambiguous relationships with post-revolution Iranian elite. In the same way, not all of Shias of Persian Gulf was “fascinated” by “Islamic revolution” in Iran and became admirers of R. Khomeini’s conception of “vilayat-e-faqih”. In addition, the author traces history of local political Shia movements, that are, in fact, more influential on domestic politics of Gulf countries that mythical “Iran’s hand”.

Conflict in the Currents: The Cross-boundary Consequences of Larval Dispersal

Science.gov (United States)

Rising, J. A.; Ramesh, N.; Dookie, D.

2016-02-01

As commercial fish populations decline in many regions, the increasing demand for ocean resources can create conflicts along international boundaries. Because fish stock ranges do not respect political boundaries, neighboring countries can impact each other through the management of the stocks within their exclusive economic zones. By combining spawning and larvae information from the FishBase database with current velocities from ocean reanalyses using a particle tracking scheme, we construct a measure of the cross-boundary diffusion of fish larvae for 40 major exploited species. These flows represent important connections both for fish populations and for fisheries and the people who depend on them, but these connections rely on fisheries management in the 'source' countries. We then use socioeconomic data on the national importance of these fish to identify hotspots for potential conflict. Finally, we consider how ranges will shift under climate change, and the social impacts of these shifts.

Political symbols and political transitions

Directory of Open Access Journals (Sweden)

Herrero de Miñón, Miguel

2006-11-01

Full Text Available Politics, Law and Psychology are fields that come together in the symbolic. This text takes evidence from those three areas to develop an analysis of political symbols and political transitions. The development of the analysis goes through three stages. The first succinctly describes the concept of transition and its meaning. The second closely examines the notion of the symbol, in terms of its definition, to explain aspects that allow us to understand it, characterise it and make its functions clear. Finally, from the author's experience as a witness and as an actor, I suggest three ways of understanding symbols in the processes of political transition: as symbols of change, as symbols of acknowledgment, and as symbols of support.

International boundary experiences by the United Nations

Science.gov (United States)

Kagawa, A.

2013-12-01

Over the last few decades, the United Nations (UN) has been approached by Security Council and Member States on international boundary issues. The United Nations regards the adequate delimitation and demarcation of international boundaries as a very important element for the maintenance of peace and security in fragile post-conflict situations, establishment of friendly relationships and cross-border cooperation between States. This paper will present the main principles and framework the United Nations applies to support the process of international boundary delimitation and demarcation activities. The United Nations is involved in international boundary issues following the principle of impartiality and neutrality and its role as mediator. Since international boundary issues are multi-faceted, a range of expertise is required and the United Nations Secretariat is in a good position to provide diverse expertise within the multiple departments. Expertise in different departments ranging from legal, political, technical, administrative and logistical are mobilised in different ways to provide support to Member States depending on their specific needs. This presentation aims to highlight some of the international boundary projects that the United Nations Cartographic Section has been involved in order to provide the technical support to different boundary requirements as each international boundary issue requires specific focus and attention whether it be in preparation, delimitation, demarcation or management. Increasingly, the United Nations is leveraging geospatial technology to facilitate boundary delimitation and demarcation process between Member States. Through the presentation of the various case studies ranging from Iraq - Kuwait, Israel - Lebanon (Blue Line), Eritrea - Ethiopia, Cyprus (Green Line), Cameroon - Nigeria, Sudan - South Sudan, it will illustrate how geospatial technology is increasingly used to carry out the support.

The asymptotic structure of AdS spacetimes in the context of General Relativity coupled to the Maxwell field in three spacetime dimensions is analyzed. Although the fall-off of the fields is relaxed with respect to that of Brown and Henneaux, the variation of the canonical generators associated to the asymptotic Killing vectors can be shown to be finite once required to span the Lie derivative of the fields. The corresponding surface integrals then acquire explicit contributions from the electromagnetic field, and become well-defined provided they fulfill suitable integrability conditions, implying that the leading terms of the asymptotic form of the electromagnetic field are functionally related. Consequently, for a generic choice of boundary conditions, the asymptotic symmetries are broken down to ℝ⊗U(1)⊗U(1). Nonetheless, requiring compatibility of the boundary conditions with one of the asymptotic Virasoro symmetries, singles out the set to be characterized by an arbitrary function of a single variable, whose precise form depends on the choice of the chiral copy. Remarkably, requiring the asymptotic symmetries to contain the full conformal group selects a very special set of boundary conditions that is labeled by a unique constant parameter, so that the algebra of the canonical generators is given by the direct sum of two copies of the Virasoro algebra with the standard central extension and U(1). This special set of boundary conditions makes the energy spectrum of electrically charged rotating black holes to be well-behaved.

Political party affiliation, political ideology and mortality.

Science.gov (United States)

Pabayo, Roman; Kawachi, Ichiro; Muennig, Peter

2015-05-01

Ecological and cross-sectional studies have indicated that conservative political ideology is associated with better health. Longitudinal analyses of mortality are needed because subjective assessments of ideology may confound subjective assessments of health, particularly in cross-sectional analyses. Data were derived from the 2008 General Social Survey-National Death Index data set. Cox proportional analysis models were used to determine whether political party affiliation or political ideology was associated with time to death. Also, we attempted to identify whether self-reported happiness and self-rated health acted as mediators between political beliefs and time to death. In this analysis of 32,830 participants and a total follow-up time of 498,845 person-years, we find that political party affiliation and political ideology are associated with mortality. However, with the exception of independents (adjusted HR (AHR)=0.93, 95% CI 0.90 to 0.97), political party differences are explained by the participants' underlying sociodemographic characteristics. With respect to ideology, conservatives (AHR=1.06, 95% CI 1.01 to 1.12) and moderates (AHR=1.06, 95% CI 1.01 to 1.11) are at greater risk for mortality during follow-up than liberals. Political party affiliation and political ideology appear to be different predictors of mortality. Published by the BMJ Publishing Group Limited.

Transgressing Boundaries: Belfast and the “Romance-Across-the-Divide”

Directory of Open Access Journals (Sweden)

Stephanie Schwerter

2007-03-01

Full Text Available One of the most popular sub-genres of Northern Irish Troubles fiction is the so called ‘Romance-across-the-divide’, a narrative in which two characters from different religious, cultural and social backgrounds struggle to overcome the region’s sectarian divide. As the centre of the Northern Irish conflict, Belfast epitomises the obstacles posed by the political situation for lovers attempting to defy socio-cultural and denominational boundaries. Joe Cleary argues that in the Northern Irish context the romance narrative is employed to illustrate the possibility of a reconciliation of opposed political camps. This article attempts to refute Cleary’s view. Focussing on Naomi May’s Troubles (1976, Dermot Healy’s A Goat’s Song (1994 and Kate O’Riordan’s Involved (1995 it sets out to demonstrate that unhappy unions of lovers cutting across sectarian lines serve instead largely to depict the ongoing political division within Northern Irish society and the breach between the North and the South of Ireland.

Politics Backstage - Television Documentaries, Politics and Politicians

Full Text Available This article deals with "the transformation of visibility" in political discourse on and representation of politics and politicians in resent Dansih television documentaries. Drawing on the theories of Habermas, Meyrowitz and John B. Thompson, it is argued that the political persona on television is moved closer to the individual citizen, creating a sort "mediated quasi-inter- action" giving mediated communication a stronger element of face-to-face interaction. Together with the more pervasive "live" coverage of politics and politicians, this expands media coverage to both the backstage of political processes and the private and personal backstage of politicians, changing the form of democracy and public debate.

T\\overline{T} -deformations, AdS/CFT and correlation functions

Science.gov (United States)

Giribet, Gaston

2018-02-01

A solvable irrelevant deformation of AdS3/CFT2 correspondence leading to a theory with Hagedorn spectrum at high energy has been recently proposed. It consists of a single trace deformation of the boundary theory, which is inspired by the recent work on solvable T\\overline{T} deformations of two-dimensional CFTs. Thought of as a worldsheet σ-model, the interpretation of the deformed theory from the bulk viewpoint is that of string theory on a background that interpolates between AdS3 in the IR and a linear dilaton vacuum of little string theory in the UV. The insertion of the operator that realizes the deformation in the correlation functions produces a logarithmic divergence, leading to the renormalization of the primary operators, which thus acquire an anomalous dimension. We compute this anomalous dimension explicitly, and this provides us with a direct way of determining the spectrum of the theory. We discuss this and other features of the correlation functions in presence of the deformation.

The negative energy density associated to hairy AdS solitons can be interpreted as the Casimir energy that is generated in the dual filed theory when the fermions are antiperiodic on the compact coordinate.

Fermionic halos at finite temperature in AdS/CFT

Science.gov (United States)

Argüelles, Carlos R.; Grandi, Nicolás E.

2018-05-01

We explore the gravitational backreaction of a system consisting in a very large number of elementary fermions at finite temperature, in asymptotically AdS space. We work in the hydrodynamic approximation, and solve the Tolman-Oppenheimer-Volkoff equations with a perfect fluid whose equation of state takes into account both the relativistic effects of the fermionic constituents, as well as its finite temperature effects. We find a novel dense core-diluted halo structure for the density profiles in the AdS bulk, similarly as recently reported in flat space, for the case of astrophysical dark matter halos in galaxies. We further study the critical equilibrium configurations above which the core undergoes gravitational collapse towards a massive black hole, and calculate the corresponding critical central temperatures, for two qualitatively different central regimes of the fermions: the diluted-Fermi case, and the degenerate case. As a probe for the dual CFT, we construct the holographic two-point correlator of a scalar operator with large conformal dimension in the worldline limit, and briefly discuss on the boundary CFT effects at the critical points.

AdS solutions through transgression

International Nuclear Information System (INIS)

Donos, Aristomenis; Gauntlett, Jerome P.; Kim, Nakwoo

2008-01-01

We present new classes of explicit supersymmetric AdS 3 solutions of type IIB supergravity with non-vanishing five-form flux and AdS 2 solutions of D = 11 supergravity with electric four-form flux. The former are dual to two-dimensional SCFTs with (0,2) supersymmetry and the latter to supersymmetric quantum mechanics with two supercharges. We also investigate more general classes of AdS 3 solutions of type IIB supergravity and AdS 2 solutions of D = 11 supergravity which in addition have non-vanishing three-form flux and magnetic four-form flux, respectively. The construction of these more general solutions makes essential use of the Chern-Simons or 'transgression' terms in the Bianchi identity or the equation of motion of the field strengths in the supergravity theories. We construct infinite new classes of explicit examples and for some of the type IIB solutions determine the central charge of the dual SCFTs. The type IIB solutions with non-vanishing three-form flux that we construct include a two-torus, and after two T-dualities and an S-duality, we obtain new AdS 3 solutions with only the NS fields being non-trivial.

Hmong Across Borders or Borders Across Hmong? Social and Political Influences Upon Hmong People

Directory of Open Access Journals (Sweden)

Prasit Leepreecha

2014-12-01

Full Text Available The Hmong are a transnational ethnic people, because of their dispersal from China into Southeast Asia in the early 19th century and from Southeast Asia to Western countries from 1975 onward. However, even within the context of Southeast Asia and southern China, the Hmong are a transnational ethnic group, due to state boundaries and the enforcement of international laws.Scholars speak as though the Hmong population has crossed political and legal borders by their movement across state boundaries and international borders. However, I argue that it is the political, social, and legal borders that have cut across the Hmong people and subjected them to be citizens of different modern nation-states. Even in the present time, these borders still, and continuously, play important roles that cross and divide the Hmong people into distinctive subgroups and fragments. In this article, I will start by describing the generally understood situation of Hmong being across national borders, and then will explain my argument that borders are across the Hmong.

Political Science and Political Geography: Neglected Areas, Areas for Development.

Bulk locality and entanglement swapping in AdS/CFT

Energy Technology Data Exchange (ETDEWEB)

Kelly, William R. [Center for Quantum Mathematics and Physics (QMAP),Department of Physics, University of California,Davis, CA 95616 (United States)

2017-03-29

Localized bulk excitations in AdS/CFT are produced by operators which modify the pattern of entanglement in the boundary state. We show that simple models — consisting of entanglement swapping operators acting on a qubit system or a free field theory — capture qualitative features of gravitational backreaction and reproduce predictions of the Ryu-Takayanagi formula. These entanglement swapping operators naturally admit multiple representations associated with different degrees of freedom, thereby reproducing the code subspace structure emphasized by Almheiri, Dong, and Harlow. We also show that the boundary Reeh-Schlieder theorem implies that equivalence of certain operators on a code subspace necessarily breaks down when non-perturbative effects are taken into account (as is expected based on bulk arguments).

Contemporary Political Paranoia, a Case of Political Gnosticism

Directory of Open Access Journals (Sweden)

Antonio Rivera García

2017-10-01

Full Text Available This article puts forward the concept of political paranoia as a useful category to understand some contemporary manifestations of the pathologies of power. For this aim an interdisciplinary approach has been used, namely, the knowledge provided by psychoanalysis, political philosophy, theology and literary or aesthetic studies. Freud’s and Lacan’s psychoanalysis allows us to understand why the paranoid subject is a megalomaniac and hyperrational subject who wants to be in control of everything. It is a sovereign subject, who has adapted not only to the Society of Control initially defined by Deleuze, but also to a conception of philosophy that aims for totality. After dealing with the close relationship between paranoia and conspiratorial political theory, the article explains the reason why contemporary political paranoia represents a case of the most radical political theology: political Gnosticism. This term stands for a conception of politics that reduces the Other to the condition of an absolute enemy that needs to be eliminated. Lastly, the article establishes a close link between the cure for political paranoia and the assumption of an ontology of incompleteness

Classification with an edge: Improving semantic image segmentation with boundary detection

Science.gov (United States)

Marmanis, D.; Schindler, K.; Wegner, J. D.; Galliani, S.; Datcu, M.; Stilla, U.

2018-01-01

We present an end-to-end trainable deep convolutional neural network (DCNN) for semantic segmentation with built-in awareness of semantically meaningful boundaries. Semantic segmentation is a fundamental remote sensing task, and most state-of-the-art methods rely on DCNNs as their workhorse. A major reason for their success is that deep networks learn to accumulate contextual information over very large receptive fields. However, this success comes at a cost, since the associated loss of effective spatial resolution washes out high-frequency details and leads to blurry object boundaries. Here, we propose to counter this effect by combining semantic segmentation with semantically informed edge detection, thus making class boundaries explicit in the model. First, we construct a comparatively simple, memory-efficient model by adding boundary detection to the SEGNET encoder-decoder architecture. Second, we also include boundary detection in FCN-type models and set up a high-end classifier ensemble. We show that boundary detection significantly improves semantic segmentation with CNNs in an end-to-end training scheme. Our best model achieves >90% overall accuracy on the ISPRS Vaihingen benchmark.

Is the political animal politically ignorant? Applying evolutionary psychology to the study of political attitudes.

Science.gov (United States)

Petersen, Michael Bang; Aarøe, Lene

2012-12-20

As evidenced by research in evolutionary psychology, humans have evolved sophisticated psychological mechanisms tailored to solve enduring adaptive problems of social life. Many of these social problems are political in nature and relate to the distribution of costs and benefits within and between groups. In that sense, evolutionary psychology suggests that humans are, by nature, political animals. By implication, a straightforward application of evolutionary psychology to the study of public opinion seems to entail that modern individuals find politics intrinsically interesting. Yet, as documented by more than fifty years of research in political science, people lack knowledge of basic features of the political process and the ability to form consistent political attitudes. By reviewing and integrating research in evolutionary psychology and public opinion, we describe (1) why modern mass politics often fail to activate evolved mechanisms and (2) the conditions in which these mechanisms are in fact triggered.

Religion, culture and political corruption in Nigeria

Dhikru A. Yagboyaju

2017-10-01

Full Text Available For so long, development theories and practices have either deliberately neglected or simply overlooked the possible interconnections between religion, culture and the attainment of development goals. Against this background, this article reviews the literature on corruption, as a major factor of underdevelopment in Nigeria, particularly as it relates to religion and culture in the country. In its analysis, this article argues that corruption in Nigeria, especially in view of the country’s multi-ethnic and multi-religious status, must be conceived as a phenomenon transcending legal, political and economic boundaries. The study adopts an interpretative and descriptive methodology for its analysis.

It is shown that the appearance of the partisan becomes possible when the socio-political uncertainty in the state and social anomie in society caused serious set into question the legitimacy of the sovereign. In such circumstances, falling value of public institutions, the rule of law and the rules of the routine, but the role of the individual and adopt independent decisions, in each case, increases. And increasing the area of independent ad hoc decisions. Such conditions arise in the occupied territory, especially in a situation of the continuing war. Besides, here indigenous people without taking any illegal actions, from the point of view of both clashing sovereigns, it is struck in the rights. All this makes a real opportunity to show the political subjectivity of the citizen, even with low social status. The behavior of the occupied population can follow three models: expectations of the solution of the conflict between sovereigns and the subsequent acceptance of its results as due - absolute majority population, the active help to the occupying sovereign for the purpose of the statement new political - the collaborator, active opposition of the occupying authority for the purpose of return former political - the partisan.

Performing Politics

Troy R. E. Paddock

2016-01-01

Full Text Available Walter Benjamin’s observation that fascism turns politics into aesthetics is, by now, a well-worn idea. This article argues that Benjamin’s critique of politics can apply just as much to the modern democratic politics of the United States. Borrowing from Benjamin, Jürgen Habermas, and Carl Schmitt, this article suggests that modern political discourse in the United States does not follow the classical liberal ideal of rational discourse in the marketplace of ideas within the public sphere. Instead, contemporary politics has become spectacle where images and slogans replace thought and debate in a 24/7 news cycle and political infotainment programs. The result is that progressives and conservatives have their own political “ecospheres” which enable them to have their own perspective reinforced, and debate is replaced by straw man arguments and personal attacks.

Politics as Culture: Contribution of Political Science to Democratic Maturity

Directory of Open Access Journals (Sweden)

Ivan Padjen

2014-01-01

Full Text Available The article discusses the contribution of Croatian political science to the development of democracy in Croatia. The focus of the analysis is the concept of culture which author talks about in five steps. In the first step it is understood in the modern key, in the second step as different for nature and in the third as different from society. In the fourth step author differentiates political culture from political economy and political institutions, but in the fifth part there is an attempt to show culture as a fundamental part of politics, policy and polity. On the basis of these insights author shows that the matrix of Croatian political science is more and more devoted to scientific investigation of politics as culture as both study of political culture and as a source of development as politics as culture.

Political psychology is a dynamic field of research that offers a unique blend of approaches and methods in the social and cognitive sciences. Political psychologists explore the interactions between macrolevel political structures and microlevel factors such as decision-making processes, motivations, and perceptions. In this article, we provide a broad overview of the field, beginning with a brief history of political psychology research and a summary of the primary methodological approaches in the field. We then give a more detailed account of research on ideology and social justice, two topics experiencing a resurgence of interest in current political psychology. Finally, we cover research on political persuasion and voting behavior. By summarizing these major areas of political psychology research, we hope to highlight the wide variety of theoretical and methodological approaches of cognitive scientists working at the intersection of psychology and political science.

Politics for cities, cities for the political. About possibility (and necessity of radical urban politics

Directory of Open Access Journals (Sweden)

Wiktor Marzec

2010-01-01

Full Text Available Essay faces the problem of determinacy of global capitalism processes for the reality of urban political life. The city is naturally communitarian form of human life and seems to be the place where radical pro-community politics could be undertaken. Already existing and operating forms of power could fruitfully influence the city social relations. Values and norms of conduct are broadly delegated on the urban space and materiality, thus conscious shaping of city space has severe consequences for community life. If a crisis of the political partly has its roots in metamorphoses of the cities, then also remedies, rising from the urban materiality and reestablishing political subjects, could be thought. City, as most real place of political life could be either reduced to the aggregate of consumers or reestablished as a political community. Due to this is the place where undesired course of action could be stopped, hence precisely here the radical democratic politics can emerge.

Political Values or the Value of Politics

Directory of Open Access Journals (Sweden)

Simoska, Emilija

2016-04-01

Full Text Available This essay was motivated by the gap between proclaimed democratic principles and the perceptions of politics which are exhibited by the citizens in transitional countries -more specifically in the Republic of Macedonia. It is based on research data collected in the past few decades, which illustrate that, in their political actions, the citizens are highly motivated by personal benefits and profits, rather than by their internalized values and ideologies. Non-democratic, authoritarian values prevail, while politics is perceived as a value itself, in the most materialistic meaning of the word. It creates a suitable milieu for growth of corruption, nepotism and clientelism. The authors conclude that such a circulus vitsiosus is a corner stone of the Macedonian political regime, and an enormous obstacle for the advancement of the participative, democratic political culture in reality, in spite of its formal acceptance.

Integrating medical and environmental sociology with environmental health: crossing boundaries and building connections through advocacy.

Science.gov (United States)

Brown, Phil

2013-06-01

This article reviews the personal and professional processes of developing an interdisciplinary approach to understanding the complex issues of environmental health in their community, political-economic, social science, and scientific contexts. This interdisciplinary approach includes a synthesis of research, policy work, and advocacy. To examine multiple forms of interdisciplinarity, I examine pathways of integrating medical and environmental sociology via three challenges to the boundaries of traditional research: (1) crossing the boundaries of medical and environmental sociology, (2) linking social science and environmental health science, and (3) crossing the boundary of research and advocacy. These boundary crossings are discussed in light of conceptual and theoretical developments of popular epidemiology, contested illnesses, and health social movements. This interdisciplinary work offers a more comprehensive sociological lens for understanding complex problems and a practical ability to join with scientists, activists, and officials to meet public health needs for amelioration and prevention of environmental health threats.

In Hungary one can mostly find references to the psychological processes of politics in the writings of publicists, public opinion pollsters, philosophers, social psychologists, and political analysts. It would be still important if not only legal scientists focusing on political institutions or sociologist-politologists concentrating on social structures could analyse the psychological aspects of political processes; but one could also do so through the application of the methods of political psychology. The authors review the history of political psychology, its position vis-à-vis other fields of science and the essential interfaces through which this field of science, which is still to be discovered in Hungary, connects to other social sciences. As far as its methodology comprising psycho-biographical analyses, questionnaire-based queries, cognitive mapping of interviews and statements are concerned, it is identical with the psychiatric tools of medical sciences. In the next part of this paper, the focus is shifted to the essence and contents of political psychology. Group dynamics properties, voters' attitudes, leaders' personalities and the behavioural patterns demonstrated by them in different political situations, authoritativeness, games, and charisma are all essential components of political psychology, which mostly analyses psychological-psychiatric processes and also involves medical sciences by relying on cognitive and behavioural sciences. This paper describes political psychology, which is basically part of social sciences, still, being an interdisciplinary science, has several ties to medical sciences through psychological and psychiatric aspects.

Thinking and meddling with boundaries: Critical reflections on Matthew Weinstein's narrative of street medics, red-zones and glop

Alsop, Steve

2015-03-01

In pursuit of more mindful notions of hybridity, this review essay provides a series of reflections on Mathew Weinstein's representations of Street Medics and `sciences for the red zones of neoliberalism'. My analysis draws on three popular ways of thinking with boundaries to offer a critical reading of the boundary-work that the essay performs with respect to three dialectics: (1) technical and political; (2) disciplinarily and multidisciplinarities; and (3) structures and agencies. I conclude with reflections on my boundary labour as a researcher, writer and pedagogue and how such cultural work might learn to live better with difference, ambiguities, hybrids and cross-hybrid learning.

Hawking radiation from AdS black holes

Hubeny, Veronika E; Rangamani, Mukund; Marolf, Donald

2010-01-01

We study Hartle-Hawking-like states of quantum field theories on asymptotically AdS black hole backgrounds, with particular regard to the phase structure of interacting theories. By a suitable analytic continuation we show that the equilibrium dynamics of field theories on large asymptotically AdS black holes can be related to the low-temperature states of the same field theory on the AdS soliton (or pure AdS) background. This allows us to gain insight into Hartle-Hawking-like states on large-radius Schwarzschild- or rotating-AdS black holes. Furthermore, we exploit the AdS/CFT correspondence to explore the physics of strongly coupled large N theories on asymptotically AdS black holes. In particular, we exhibit a plausibly complete set of phases for the M2-brane world-volume superconformal field theory on a BTZ black hole background. Our analysis partially resolves puzzles previously raised in connection with Hawking radiation on large AdS black holes.

Everyday politics, social practices and movement networks: daily life in Barcelona's social centres.

Science.gov (United States)

Yates, Luke

2015-06-01

The relations between everyday life and political participation are of interest for much contemporary social science. Yet studies of social movement protest still pay disproportionate attention to moments of mobilization, and to movements with clear organizational boundaries, tactics and goals. Exceptions have explored collective identity, 'free spaces' and prefigurative politics, but such processes are framed as important only in accounting for movements in abeyance, or in explaining movement persistence. This article focuses on the social practices taking place in and around social movement spaces, showing that political meanings, knowledge and alternative forms of social organization are continually being developed and cultivated. Social centres in Barcelona, Spain, autonomous political spaces hosting cultural and educational events, protest campaigns and alternative living arrangements, are used as empirical case studies. Daily practices of food provisioning, distributing space and dividing labour are politicized and politicizing as they unfold and develop over time and through diverse networks around social centres. Following Melucci, such latent processes set the conditions for social movements and mobilization to occur. However, they not only underpin mobilization, but are themselves politically expressive and prefigurative, with multiple layers of latency and visibility identifiable in performances of practices. The variety of political forms - adversarial, expressive, theoretical, and routinized everyday practices, allow diverse identities, materialities and meanings to overlap in movement spaces, and help explain networks of mutual support between loosely knit networks of activists and non-activists. An approach which focuses on practices and networks rather than mobilization and collective actors, it is argued, helps show how everyday life and political protest are mutually constitutive. © London School of Economics and Political Science 2014.

The demarcation of arbitrary boundaries for coastal zone management: the Israeli case.

Science.gov (United States)

Sas, Eliraz; Fischhendler, Itay; Portman, Michelle E

2010-11-01

Integrated coastal zone management (ICZM) addresses the interconnections, complexities, and conflicts between many users of the coastal area with different goals. It requires setting managerial boundaries that capture many elements of human and natural systems. Experience teaches us that without a directed effort managerial rules and laws are not likely to coincide with the physical sensitivity of units that reflect different environmental characteristics of the coastal zone. Hence the aim of this study is to explore why coastal managerial boundaries are set arbitrarily and whether and how it is possible to address the problems this poses. We examine what influences the decisions of a new coastal management authority in Israel to determine how this body overcomes the limits of arbitrary boundary demarcation. The study found that real life management succeeded to both address areas outside the arbitrary boundaries and also to respect some of the different socio-economic needs and physical constraints of the coastal sub-units. Israel's Coastal Environment Protection Law allows and, in fact, encourages the regulator to use discretion and to employ various criteria to balance development and conservation. This implies that policy makers are cognizant of a need to balance ecologically-sensitive boundaries that consider the homogeneity of the coast with politically feasible boundaries that are set arbitrarily.

The political reference point: How geography shapes political identity.

Feinberg, Matthew; Tullett, Alexa M; Mensch, Zachary; Hart, William; Gottlieb, Sara

2017-01-01

It is commonly assumed that how individuals identify on the political spectrum-whether liberal, conservative, or moderate-has a universal meaning when it comes to policy stances and voting behavior. But, does political identity mean the same thing from place to place? Using data collected from across the U.S. we find that even when people share the same political identity, those in "bluer" locations are more likely to support left-leaning policies and vote for Democratic candidates than those in "redder" locations. Because the meaning of political identity is inconsistent across locations, individuals who share the same political identity sometimes espouse opposing policy stances. Meanwhile, those with opposing identities sometimes endorse identical policy stances. Such findings suggest that researchers, campaigners, and pollsters must use caution when extrapolating policy preferences and voting behavior from political identity, and that animosity toward the other end of the political spectrum is sometimes misplaced.

Uncovering the political in non-political young muslim immigrant identities

Niels Nørgaard Kristensen

2011-01-01

Full Text Available The theme of this paper is political identity and participation amongMuslim migrant young people in Denmark. Political identity is analysedby examining students’ political interests and perception of themselves as participants in politics, as well as their rationalities for politics. In order to address the research question ‘What characterizes political identities among Muslim immigrant young people in schools?’ we interviewed eight Muslim students from a Danish upper secondary school and from different national origins. The students’ political orientations seemed quite contradictory, even among those who might readily have been identified as a-political. Despite moderate political interest, all students showed some inclinations to participate in elections or in particular issues. However, they emphasized that their social studies classes primarily provided them with factual knowledge experience, and some students found this knowledge useful. None of the students seemed to experience school as an arena for participation. Consequently, there is first a need to emphasize the significance of a dynamic perspective on the phenomenon of political identity, and second, we need to know how students in school should be regarded as citizens in ‘the making’ or as equal citizens in a participatory arena.

Such findings suggest that researchers, campaigners, and pollsters must use caution when extrapolating policy preferences and voting behavior from political identity, and that animosity toward the other end of the political spectrum is sometimes misplaced.

The political reference point: How geography shapes political identity.

Directory of Open Access Journals (Sweden)

Matthew Feinberg

Full Text Available It is commonly assumed that how individuals identify on the political spectrum-whether liberal, conservative, or moderate-has a universal meaning when it comes to policy stances and voting behavior. But, does political identity mean the same thing from place to place? Using data collected from across the U.S. we find that even when people share the same political identity, those in "bluer" locations are more likely to support left-leaning policies and vote for Democratic candidates than those in "redder" locations. Because the meaning of political identity is inconsistent across locations, individuals who share the same political identity sometimes espouse opposing policy stances. Meanwhile, those with opposing identities sometimes endorse identical policy stances. Such findings suggest that researchers, campaigners, and pollsters must use caution when extrapolating policy preferences and voting behavior from political identity, and that animosity toward the other end of the political spectrum is sometimes misplaced.

Full Text Available The music-compositional principles of commercial and political advertising and also the self-promotion of electronic media (radio, television, Internet are considered in this mediatext: from the elementary beeps, symbolic functions, emblems/logos and musical brands to the sound engineering technology to underscore the product's name and the complex synthesis between music and intra movements and color-light design of frames. Simultaneously examines, how the musical arrangement of ethereal advertising is involved in creation the emotional drama or bravado which reach the level of explicit or associative counterpoint 'music with the advertised object or subject' and which extend to expression of cultural image of all the broadcast channel. The article explores the works of the next genres like infomercial, teleshopping, film-ad, and autonomous commercials that have been produced in European countries or USA.

Resource Windfalls, Political Regimes, and Political Stability

OpenAIRE

2011-01-01

We study theoretically and empirically whether natural resource windfalls affect political regimes. We document the following regularities. Natural resource windfalls have no effect on the political system when they occur in democracies. However, windfalls have significant political consequences in autocracies. In particular, when an autocratic country receives a positive shock to its flow of resource rents it responds by becoming even more autocratic. Furthermore, there is heterogeneity in t...

Party Political Panthers: Hegemonic Tamil Politics and the Dalit Challenge

Directory of Open Access Journals (Sweden)

Hugo Gorringe

2011-12-01

Full Text Available The Viduthalai Ciruthaigal Katchi (VCK, Liberation Panther Party has successfully transformed from the largest Dalit movement in Tamil Nadu into a recognised political organisation. Social movement theorists like Gamson (1990 view political recognition and engagement as one of the main aims and successes of social mobilisation. Despite the obvious achievements of the VCK, however, activists and commentators express disappointment or disillusionment with its performance. The Panthers clearly reject the caste hierarchy, but they increasingly adopt hegemonic forms of politics which can undermine their aims. This paper, thus, engages with the questions of movement institutionalisation by tracing the political trajectory of the VCK and charting its resistance to and compliance with Dravidian hegemony. It argues that institutionalisation needs to be understood within particular socio-political contexts and notes how the hegemony of Dravidian politics partly explains the disjuncture between activist and political perceptions. It portrays how the dominant political parties have set the template for what it means to ‘do’ politics in Tamil Nadu which serves as both an opportunity and a constraint for potential challengers.

The politics of researching global health politics

Science.gov (United States)

Rushton, Simon

2015-01-01

In this comment, I build on Shiffman’s call for the global health community to more deeply investigate structural and productive power. I highlight two challenges we must grapple with as social scientists carrying out the types of investigation that Shiffman proposes: the politics of challenging the powerful; and the need to investigate types of expertise that have traditionally been thought of as ‘outside’ global health. In doing so, I argue that moving forward with the agenda Shiffman sets out requires social scientists interested in the global politics of health to be reflexive about our own exercise of structural and productive power and the fact that researching global health politics is itself a political undertaking.

Highlights: • The reduction of the recirculation zone and the stability of the free surface are key issues in the target. • A swirl is numerically added in the target to make the recirculation zone small and stable. • Numerical simulation with different boundary conditions is carried out. • Physical analysis is presented to explain the numerical results. - Abstract: Aiming the key issues in the accelerator driven system (ADS), windowless spallation target focus on the minimization of the recirculation zone and on the stability of the free surface, an innovation has been made by numerically adding swirl to the fluid at the inlet. At first, two phase flow pattern in the simulation is compared with the experiments and numerical method is employed correctly. The results reveal that the recirculation zone and the flow pattern are greatly influenced when the swirl strength is changed from 1.0 rad/s to 2.5 rad/s. The height of the recirculation zone decreases with increase in swirl strength and completely disappears when the swirl strength reaches 2.0 rad/s. In addition, larger swirl strength leads to different flow pattern and a new cavitation zone is generated under the recirculation zone. The Bernoulli's equation and angular momentum conservation are applied to make it clear that this phenomena is due to the decrease of the axial pressure caused by the radial velocity. Moreover, the new cavitation zone totally links to the vapor area above the recirculation zone when the swirl strength is 2.5 rad/s. The results are very helpful to the design and optimization of the ADS windowless spallation target.

Full Text Available Modern society is changing under the influence of IT technologies, more and more we talk about 'digital revolution', and political and economic developments are shaped by computer networks. Undeniably, the Internet has opened new possibilities for socio-political expansion, networking and mobilization. Besides the political establishment, many social movements found their chance in cyberspace recognizing the IT technology as a platform for the development and improvement of their internal and external communication. In this article we will focus on the Pirate Party, movement that has been seriously growing on the European political stage for last several years. Following the example of German Pirate Party we will try to explain the characteristics of the movement, its goals and communication strategies, and political dilemmas which it brings.

The institutionalization of River Basin Management as politics of scale - Insights from Mongolia

Science.gov (United States)

Houdret, Annabelle; Dombrowsky, Ines; Horlemann, Lena

2014-11-01

River Basin Management (RBM) as an approach to sustainable water use has become the dominant model of water governance. Its introduction, however, entails a fundamental realignment and rescaling of water-sector institutions along hydrological boundaries. Creating such a new governance scale is inherently political, and is being described as politics of scale. This paper analyzes how the politics of scale play out in the institutionalization of RBM in Mongolia. It furthermore scrutinizes the role of the broader political decentralization process in the introduction of RBM, an issue that has so far received little attention. Finally, it assesses whether the river basin is an adequate water management scale in Mongolia. This article finds that institutionalizing RBM in Mongolia is indeed a highly political negotiation process that does not only concern the choice of the governance scale, but also its detailed institutional design. It furthermore reveals that Mongolia's incomplete political decentralization process has for a long time negatively impacted the decentralization of water-related tasks and the implementation of RBM. However, the 2011 Budget Law and the 2012 Water Law provide for a fiscal strengthening of local governments and clearer sharing of responsibilities among the various different institutions involved in water management. Nevertheless, only if the 2012 Water Law is complemented by adequate by-laws - and if the newly created river basin institutions are adequately equipped - can RBM be effectively put into practice. This article confirms the usefulness of a politics-of-scale approach to understand scalar practices and changes in water management. However, the article also argues for a broadening of the analytical perspective to take the interdependencies between changes in water governance and other political processes, such as decentralization, into account.

Putting politics first.

Science.gov (United States)

Hacker, Jacob S

2008-01-01

The greatest lesson of the failure of comprehensive health reform in the early 1990s is that politics comes first. Even the best-laid policy plans are worthless if they lack the political support to pass. Putting politics first means avoiding the overarching mistake of the Clinton reformers: envisioning a grand policy compromise rather than hammering out a real political compromise. It also means addressing the inevitable fears of those who believe that they are well protected by our eroding employment-based system. And it means formulating political strategies that are premised on the contemporary realities of the hyperpolarized U.S. political environment, rather than wistfully recalled images of the bipartisan politics of old.

Nonetheless, such a simple opposition should only work as a starting point for an interrogation of both terms and how they have come to look and function as empirical and analytical categories. Focusing on the ways that religion is played out in relation to politics reveals different historical and cultural...... constellations and positions, which can be highlighted as variations of religion as politics, religion in politics, religion out of politics, and religion not politics....

It taps its data from apologetic speeches by political officials and from apologies rendered to politicians. The paper discusses the semantics and pragmatics of political apology. It examines the use of the language of apology, paying attention to expressives, commissives and persuasion, by drawing on the speech act of apology and political discourse analysis (PDA. It concludes that the obligation on the part of the offender to apologise and for the offended to accept the apology and to forgive for socio-political harmony is driven by both the social pact and the Ghanaian communalistic context.

Politics in evaluation: Politically responsive evaluation in high stakes environments.

2015-12-01

The role of politics has often been discussed in evaluation theory and practice. The political influence of the situation can have major effects on the evaluation design, approach and methods. Politics also has the potential to influence the decisions made from the evaluation findings. The current study focuses on the influence of the political context on stakeholder decision making. Utilizing a simulation scenario, this study compares stakeholder decision making in high and low stakes evaluation contexts. Findings suggest that high stakes political environments are more likely than low stakes environments to lead to reduced reliance on technically appropriate measures and increased dependence on measures better reflect the broader political environment.

I was enthused to prepare this review article as there does not exist any of such simplified introduction of one of the prominent sub-fields in cultural anthropology for the Nepalis readers, in particular. I believe this particular sub-field has to offer much to understand and explain the recent trends and current turmoil of the political transition in the country. Political anthropologists than any other could better explain how the politics is socially and culturally embedded and intertwined, therefore, separation of the two – politics from social and cultural processes – is not only impossible but methodologically wrong, too.

Our goal is to recognize the structure of political spectacle in BiH political scene and point out the functions and objectives of this relatively new term in the media and the political sphere. In this regard, we have observed a political spectacle as a method of political communication of the rulers to the ruled. A very important element of the political spectacle is the media. With the media promotion of this method of political communication achieves its full capacity. The final outcome of the political spectacle is reflected in manipulating the public. In this way the politicians try to remain in power as long as they can.

Political legitimacy and approval of political protest and violence among children and adolescents.

Science.gov (United States)

Funderburk, C

1975-06-01

A question of general theoretical relevance for political socialization research concerns the role played by basic political orientations in structuring specific political opinions. This report investigates the relationship between beliefs in the legitimacy of political objects and approval of political protest and violence among a sample of children and adolescents. The setting for the research was a Florida town. Four aspects of political legitimacy are defined and measured. Measures of approval of political protest and political violence are distinguished conceptually and empirically. Beliefs in political legitimacy are shown to be of considerable importance in structuring opinions about political violence but have little impact on opinions about protest.

We present a manifestly T-dual formulation of curved spaces such as an AdS space. For group manifolds related by the orthogonal vielbein fields the three form H=dB in the doubled space is universal at least locally. We construct an affine nondegenerate doubled bosonic AdS algebra to define the AdS space with the Ramond-Ramond flux. The non-zero commutator of the left and right momenta leads to that the left momentum is in an AdS space while the right momentum is in a dS space. Dimensional reduction constraints and the physical AdS algebra are shown to preserve all the doubled coordinates.

POLITICAL PARTIES AND THEIR ROLE IN SAFEGUARDING THE SUPREMACY OF THE CONSTITUTION

Directory of Open Access Journals (Sweden)

Silvia-Elena, OLARU

2014-11-01

Full Text Available Nowadays, the political scene of the world is stirred by political parties. The separate fronts of the Government, on the one side, and Parliament, on the other, are now obsolete notions, while political parties dominate social life, having become genuine states in state. Therefore, within the contemporary organization of the powers in state, the issues are assessed from a different perspective: traditional structures are maintained, while their functions evolve and transform rapidly. A modern society without political parties is unconceivable. Today, more than ever, political parties deserve their qualification of "engines of political life" and "reasons of the aging of the classical theory of the separation of powers"; at the same time, they must act within the boundaries set by law, namely by observing the principles of a democratic state and the constitutional order. When dealing with the theory of the separation of powers in state, we must keep in mind that, to a large extent, it was developed in a time in which political parties did not exist yet or were not in their modern form. The main problems were of institutional nature and referred to the various bodies, their competencies and the relationships between them. Unfortunately, in societies in transition, where authentic democracy is still developing, political parties - in some countries - perceive governing as a means of obtaining ministerial portfolios at all costs, irrespective of whether they have professionals for the field concerned or not. This often creates a governmental crisis, which usually leads to changing the incumbents and obtaining more positions in the new government. In this context, some of the incumbent parties set up all kinds of obstacles in order to limit the number of parties, and if this limitation fails, they manage to create legal provisions which discriminate among parties with seats in Parliament and those which are not represented, both in local and

Full Text Available The article discusses the skeptical view that on-line forms of politial participation have thus far had only little importance for democracy. Based on an analysis of the interplay between the supply of, and the demands for, e-tools for political informaiton and deliberation at the local level in Denmark, it is concluded that the skeptical view is con- firmed to some extent; however, It is also shown that something more - as well as something new - is added to the local political public, both in terms of the citizens involved and the topics discussed. Further- more, the case study indicates that online deliberations have had a number of minor effects on local political opinionformation and deci- sion-making. Thus, the overall conclusion is that a local forum of digital deliberations has the potential to form an alternative channel for raising issues and forming a vehicle for involving more citizens in politics, including citizens with weak resources.

We consider four-dimensional gravity in the presence of a dilatonic scalar field and an Abelian gauge field. This theory corresponds to the bosonic sector of a Kaluza-Klein reduction of eleven-dimensional supergravity which induces a specific self-interacting potential for the scalar field. We compute the conserved charges and carry out the thermodynamics of an anti-de Sitter (AdS) dyonic black hole solution that was proposed recently. The charges coming from symmetries of the action are computed using the Regge-Teitelboim Hamiltonian approach. They correspond to the mass, which acquires contributions from the scalar field, and the electric charge. We introduce integrability conditions because the scalar field leads to non-integrable terms in the variation of the mass. These conditions are generically solved by introducing boundary conditions that relate the leading and subleading terms of the scalar field fall-off. The Hamiltonian Euclidean action, computed in the grand canonical ensemble, is obtained by demanding the action to have an extremum. Its value is given by a radial boundary term plus an additional polar angle boundary term due to the presence of a magnetic monopole. Remarkably, the magnetic charge can be identified from the variation of the additional polar angle boundary term, confirming that the first law of black hole thermodynamics is a consequence of having a well-defined and finite Hamiltonian action principle, even if the charge does not come from a symmetry of the action. The temperature and electrostatic potential are determined by demanding regularity of the black hole solution, whereas the value of the magnetic potential is determined by the variation of the additional polar angle boundary term. Consequently, the first law of black hole thermodynamics is identically satisfied by construction.

Numerical simulation of two-dimensional flows over a circular cylinder using the immersed boundary method

International Nuclear Information System (INIS)

Lima E Silva, A.L.F.; Silveira-Neto, A.; Damasceno, J.J.R.

2003-01-01

In this work, a virtual boundary method is applied to the numerical simulation of a uniform flow over a cylinder. The force source term, added to the two-dimensional Navier-Stokes equations, guarantees the imposition of the no-slip boundary condition over the body-fluid interface. These equations are discretized, using the finite differences method. The immersed boundary is represented with a finite number of Lagrangian points, distributed over the solid-fluid interface. A Cartesian grid is used to solve the fluid flow equations. The key idea is to propose a method to calculate the interfacial force without ad hoc constants that should usually be adjusted for the type of flow and the type of the numerical method, when this kind of model is used. In the present work, this force is calculated using the Navier-Stokes equations applied to the Lagrangian points and then distributed over the Eulerian grid. The main advantage of this approach is that it enables calculation of this force field, even if the interface is moving or deforming. It is unnecessary to locate the Eulerian grid points near this immersed boundary. The lift and drag coefficients and the Strouhal number, calculated for an immersed cylinder, are compared with previous experimental and numerical results, for different Reynolds numbers

The issue of political behaviour in contemporary bio-political discourse

Full Text Available The main topic of the article is the political. During the study it has been found tested that political behaviour is the difficult question to analyse as in bio-politics there are a lot of discussions about genetics and social origins of political behaviour. An integration model of bio-political view of political behaviour has been suggested at the article, which includes both genetics (adaptation, domination and subordination and social factors (education, socialization, the evolution of consciousness. «Homo Politicus» is genetically related with another biological Wight and this definitely influences his behavior in social and political spheres. For instance, every human being as any social primates has genetic inclination to adaptation, domination, subjugation. In case with «Homo Sapiens» this has a form of genetic and social adaptation, political domination and subjugation. The inclination to the domination from one side and to the subjugation to another side is genetically «imprinted» into the nature of the «Homo Politicus». Particularly this two features lie is the basis of his political behavior. However, it is important to mention that, nevertheless the «Homo Sapiens» shares inclination of social primates for hierarchical social organization at the same time he has developed the following capabilities, which are unique in animal world, such as: language, culture and morale. Thus, ideas and values created by the human being have commenced changing of his behavior in social and political sphere. It is important to underline that in above mentioned dichotomy «genetic – culture/morale» such very core analysis element as human brain is absent. According to this, it is has to be mentioned that we keep in mind that the human brain participates in formation of every act or idea, what is fulfilled in the process of the political supervision of subject of management, as well as in the process of social action of management object

Nonlinear realization of supersymmetric AdS space isometries

International Nuclear Information System (INIS)

Clark, T. E.; Love, S. T.

2006-01-01

The isometries of AdS 5 space and supersymmetric AdS 5 xS 1 space are nonlinearly realized on four-dimensional Minkowski space. The resultant effective actions in terms of the Nambu-Goldstone modes are constructed. The dilatonic mode governing the motion of the Minkowski space probe brane into the covolume of supersymmetric AdS 5 space is found to be unstable and the bulk of the AdS 5 space is unable to sustain the brane. No such instability appears in the nonsupersymmetric case

Political Culture and Covalent Bonding. A Conceptual Model of Political Culture Change

Camelia Florela Voinea

2015-01-01

Full Text Available Our class of models aims at explaining the dynamics of political attitude change by means of the dynamic changes in values, beliefs, norms and knowledge with which it is associated. The model constructs a political culture perspective over the relationship between macro and micro levels of a society and polity. The model defines the bonding mechanism as a basic mechanism of the political culture change by taking inspiration from the valence bonding theory in Chemistry, which has inspired the elaboration of the mechanisms and processes underlying the political culture emergence and the political culture control over the relationship between macro-level political entities and the micro-level individual agents. The model introduces operational definitions of the individual agent in political culture terms. The simulation model is used for the study of emergent political culture change phenomena based on individual interactions (emergent or upward causation as well as the ways in which the macro entities and emergent phenomena influence in turn the behaviors of individual agents (downward causation. The model is used in the ongoing research concerning the quality of democracy and political participation of the citizens in the Eastern European societies after the Fall of Berlin Wall. It is particularly aimed at explaining the long-term effect of the communist legacy and of the communist polity concept and organization onto the political mentalities and behaviors of the citizens with respect to democratic institutions and political power. The model has major implications in political socialization, political involvement, political behavior, corruption and polity modeling.

The boundaries of poverty in Bogota

Full Text Available The article proposes an analytical perspective on poverty with a multidimensional approach, not only as an aggregate of variables and indicators, but also using a probing strategy that considers the way in which it is perceived between the groups receiving programs to alleviate poverty or use subsidized public services, and those without. Based on tools for quantitative and qualitative analysis applied to data collected on a sample of residents of Bogota, the authors analyze how the boundaries of sense on poverty are related to both objective and subjective factors related to being or not users of these programs, socioeconomic and educational conditions, as well as political participation, degree of association and use of mechanisms to enforce civil rights.

Non-relativistic AdS branes and Newton-Hooke superalgebra

International Nuclear Information System (INIS)

Sakaguchi, Makoto; Yoshida, Kentaroh

2006-01-01

We examine a non-relativistic limit of D-branes in AdS 5 x S 5 and M-branes in AdS 4/7 x S 7/4 . First, Newton-Hooke superalgebras for the AdS branes are derived from AdS x S superalgebras as Inoenue-Wigner contractions. It is shown that the directions along which the AdS-brane worldvolume extends are restricted by requiring that the isometry on the AdS-brane worldvolume and the Lorentz symmetry in the transverse space naturally extend to the super-isometry. We also derive Newton-Hooke superalgebras for pp-wave branes and show that the directions along which a brane worldvolume extends are restricted. Then the Wess-Zumino terms of the AdS branes are derived by using the Chevalley-Eilenberg cohomology on the super-AdS x S algebra, and the non-relativistic limit of the AdS-brane actions is considered. We show that the consistent limit is possible for the following branes: Dp (even,even) for p = 1 mod 4 and Dp (odd,odd) for p = 3 mod 4 in AdS 5 x S 5 , and M2 (0,3), M2 (2,1), M5 (1,5) and M5 (3,3) in AdS 4 x S 7 and S 4 x AdS 7 . We furthermore present non-relativistic actions for the AdS branes

Introduction: The micro-politics of knowledge production in Southern Africa

Directory of Open Access Journals (Sweden)

Andrew Bank

Full Text Available This issue of Kronos: Southern African Histories proposes a scaling down from analyses of scientific and institutional authority toward the micro-politics in the work of knowledge production. The articles locate the operations of power and affect in the interactions of individuals situated within networks. While histories of science in southern Africa are still sparse, these essays build on the region's rich micro-historical and biographical traditions and on developments in science studies globally. The twelve articles in this issue lie in the period from around 900 through to the present and their geographical range includes contemporary Zambia, Zimbabwe, Mozambique and South Africa. This introduction discusses them thematically. The first theme 'Controlling and Classifying Nature' (articles by de Luna, Cook, Hammel, and Mwatwara and Swart explores knowledge production before the apex of imperial rule and foreground collaborations between Africans and Europeans without defining the projects in scientific or imperialist terms. These articles expose the fragile boundaries between fact and fiction, knowledge and ignorance, in historical and natural understandings. The second theme, 'The Racial Politics of Cultural Knowledge' (articles by Wright, Bank, Hansen, and Duff draws out the ideological, political, and affective motivations in scientific work and directs attention to the story of racial categories and racism in southern African science and its history more generally. The third theme, 'Local and Global Racial Politics' (articles by Dubow, Magaziner and Jacobs, demonstrates the potential of intellectual biographies to establish the presence of affect in a form usually reduced to equating power and knowledge. The fourth theme, 'The Micro-Politics of Science' (article by Heywood, probes how diverse actors, including molecular biologists, museum staff and conservationists, interacted in the development of a scheme to breed a look-alike of an

The refugee crisis in Africa and implications for health and disease: a political ecology approach.

Science.gov (United States)

Kalipeni, E; Oppong, J

1998-06-01

Political violence in civil war and ethnic conflicts has generated millions of refugees across the African continent with unbelievable pictures of suffering and unnecessary death. Using a political ecology framework, this paper examines the geographies of exile and refugee movements and the associated implications for re-emerging and newly emerging infectious diseases in great detail. It examines how the political ecologic circumstances underlying the refugee crisis influences health services delivery and the problems of disease and health in refugee camps. It has four main themes, namely, an examination of the geography of the refugee crisis: the disruption of health services due to political ecologic forces that produce refugees; the breeding of disease in refugee camps due to the prevailing desperation and destitution; and the creation of an optimal environment for emergence and spread of disease due to the chaotic nature of war and violence that produces refugees. We argue in this paper that there is great potential of something more virulent than cholera and Ebola emerging and taking a big toll before being identified and controlled. We conclude by noting that once such a disease is out in the public rapid diffusion despite political boundaries is likely, a fact that has a direct bearing on global health. The extensive evidence presented in this paper of the overriding role of political factors in the refugee health problem calls for political reform and peace accords, engagement and empowerment of Pan-African organizations, foreign policy changes by Western governments and greater vigilance of non-governmental organizations (NGOs) in the allocation and distribution of relief aid.

Spiritual Politics

Frédéric Rambeau

2015-01-01

Full Text Available According to Foucault, the uprising of the Iranian people in the seventies reveals how much the political force of Islam is due precisely to the fact that it is not principally located in the field of politics, but in that of ethics. Religion (Shiite Islam appears as the guarantee of real change in the very mode of existence. This spiritual politics is marginalized by Marxism, where it is understood as a discontinuity in relation to proper politics, given that the latter is necessarily linked to a strategic rationalization. By indicating, at this juncture of what is intolerable, the living source and the critical impulse of the Foucauldian ethics, this spiritual politics also leads to recognize in the concept of “subjectivation” a dimension that might escape the circle of freedom as determined by a total immanence to power. This conceptual possibility is highly present in the aporias of the Foucauldian concept of the “relation to oneself”, both as a first condition of governmentality and the ultimate point of resistance against any governmentality. It thus reveals the difficulties in relating political to ethical subjectivation.

About green political parties

Orlović Slobodan P.

2015-01-01

Full Text Available In this work the author refers to some legal and political questions in connection with green political parties. Those questions cover: the ideology of green political parties, their number and influence, both in general and in Serbia. The first part of work is generally speaking about political parties - their definition, ideology, role and action. Main thesis in this work is that green political parties, by their appearance, were something new on the political scene. But quickly, because of objective and subjective reasons, they were changing original ideas and were beginning to resemble to all other political parties. In this way, they lost their vanguard and political alternativeness.

A closer look at two AdS4 branes in an AdS5 bulk

International Nuclear Information System (INIS)

Thambyahpillai, Shiyamala

2005-01-01

We investigate a scenario with two AdS 4 branes in an AdS 5 bulk. In this scenario there are two gravitons and we investigate the role played by each of them for different positions of the second brane. We show that both gravitons play a significant role only when the turn-around point in the warp factor is approximately equidistant from both branes. We find that the ultralight mode becomes heavy as the second brane approaches the turn-around point, and the physics begins to resemble that of the RS model. Thus we demonstrate the crucial role played by the turn-around in the warp factor in enabling the presence of both gravitons. (author)

Purpose and Vitality of Rumours: Political Aspects

Directory of Open Access Journals (Sweden)

Valdas Pruskus

2011-03-01

Full Text Available The article deals with social instrumental intention of rumours and their expression. It also reveals the social and political role of rumours in controlling the behaviour of a group of members and preserving its identity. The dual nature of rumours is analyzed as well as gnosiological, psychological and sociological reasons. On the one hand, the roots of rumour vitality are hidden in the dualism of this phenomenon, where in a strange way contradictory things get on well together ­ private and public, moral and immoral, the truth and the lie, between which it is not easy to draw a clear boundary even in everyday life. On the other hand, a rumour is alive because of our constant thirst for additional and fresher information, trying to perceive a person, an action or a phenomenon better. At the same time, it stimulates the proclaimers of the official political information to find the ways for the provided information to be more accurate, open, exhaustive as possible, presented in an understandable and accessible form. There the power of the effect of a rumour lays, a phenomenon without authorship, but with an authority to which, more or less, all of us are to obey.

Cohomological methods are applied for the special set of solutions corresponding to rotating branes in arbitrary dimensions, AdS black holes (which can be embedded in ten or eleven dimensions), and gauge supergravities. A new class of solutions is proposed, the Hilbert modular varieties, which consist of the 2n-fold product of the two-spaces H{sup n} /{gamma} (where H{sup n} denotes the product of n upper half-planes, H {sup 2}, equipped with the co-compact action of {gamma} is contained in SL(2, R){sup n}) and (H {sup n}){sup *}/{gamma} (where (H {sup 2}){sup *}=H {sup 2}{gamma} and {gamma} is a congruence subgroup of SL(2, R) {sup n}). The cohomology groups of the Hilbert variety, which inherit a Hodge structure (in the sense of Deligne), are analyzed, as well as bifiltered sequences, weight and Hodge filtrations, and it is argued that the torsion part of the cuspidal cohomology is involved in the global anomaly condition. Indeed, in the presence of the cuspidal part, all cohomology classes can be mapped to the boundary of the space and the cuspidal contribution can be involved in the global anomaly condition. (orig.)

The homogeneous symmetric complex domain D5=SO(5,2/SO(5×SO(2 corresponds to the conformal relativistic curved 10 real-dimensional phase space H10 associated with a particle moving in the 5D Anti de Sitter space AdS5. The geometric coupling constant associated to the gravitational force can also be obtained from the ratios of the measures involving Shilov boundaries. We also review our derivation of the observed vacuum energy density based on the geometry of de Sitter (Anti de Sitter spaces.

Usage of marketing in politics

Full Text Available Multi-party political system led to competition between political parties which caused the need for marketing in politics that improves political reputation. Politics, based on rich experience of political practice, used existing, developed methods and techniques of commercial marketing. Political marketing openly admits that politics and politicians are simply goods that are being sold on a political market. Political marketing is a whole way of operation by political parties which ask these questions: how do the voters choose; what affects their preference and how that preference can be influenced. Usage of political marketing in Bosnia and Herzegovina is still not on a satisfactory level but the knowledge about the importance of political marketing is increasing.

MAPPING CHILDREN'S POLITICS: SPATIAL STORIES, DIALOGIC RELATIONS AND POLITICAL FORMATION.

Science.gov (United States)

Elwood, Sarah; Mitchell, Katharyne

2012-03-01

This article confronts a persistent challenge in research on children's geographies and politics: the difficulty of recognizing forms of political agency and practice that by definition fall outside of existing political theory. Children are effectively "always already" positioned outside most of the structures and ideals of modernist democratic theory, such as the public sphere and abstracted notions of communicative action or "rational" speech. Recent emphases on embodied tactics of everyday life have offered important ways to recognize children's political agency and practice. However, we argue here that a focus on spatial practices and critical knowledge alone cannot capture the full range of children's politics, and show how representational and dialogic practices remain a critical element of their politics in everyday life. Drawing on de Certeau's notion of spatial stories, and Bakhtin's concept of dialogic relations, we argue that children's representations and dialogues comprise a significant space of their political agency and formation, in which they can make and negotiate social meanings, subjectivities, and relationships. We develop these arguments with evidence from an after-school activity programme we conducted with 10-13 year olds in Seattle, Washington, in which participants explored, mapped, wrote and spoke about the spaces and experiences of their everyday lives. Within these practices, children negotiate autonomy and self-determination, and forward ideas, representations, and expressions of agreement or disagreement that are critical to their formation as political actors.

Stress-assisted grain growth in nanocrystalline metals: Grain boundary mediated mechanisms and stabilization through alloying

International Nuclear Information System (INIS)

Zhang, Yang; Tucker, Garritt J.; Trelewicz, Jason R.

2017-01-01

The mechanisms of stress-assisted grain growth are explored using molecular dynamics simulations of nanoindentation in nanocrystalline Ni and Ni-1 at.% P as a function of grain size and deformation temperature. Grain coalescence is primarily confined to the high stress region beneath the simulated indentation zone in nanocrystalline Ni with a grain size of 3 nm. Grain orientation and atomic displacement vector mapping demonstrates that coalescence transpires through grain rotation and grain boundary migration, which are manifested in the grain interior and grain boundary components of the average microrotation. A doubling of the grain size to 6 nm and addition of 1 at.% P eliminates stress-assisted grain growth in Ni. In the absence of grain coalescence, deformation is accommodated by grain boundary-mediated dislocation plasticity and thermally activated in pure nanocrystalline Ni. By adding solute to the grain boundaries, the temperature-dependent deformation behavior observed in both the lattice and grain boundaries inverts, indicating that the individual processes of dislocation and grain boundary plasticity will exhibit different activity based on boundary chemistry and deformation temperature.

Field of genes: the politics of science and identity in the Estonian Genome Project.

Science.gov (United States)

Fletcher, Amy L

2004-04-01

This case study of the Estonian Genome Project (EGP) analyses the Estonian policy decision to construct a national human gene bank. Drawing upon qualitative data from newspaper articles and public policy documents, it focuses on how proponents use discourse to link the EGP to the broader political goal of securing Estonia's position within the Western/European scientific and cultural space. This dominant narrative is then situated within the analytical notion of the "brand state", which raises potentially negative political consequences for this type of market-driven genomic research. Considered against the increasing number of countries engaging in gene bank and/or gene database projects, this analysis of Estonia elucidates issues that cross national boundaries, while also illuminating factors specific to this small, post-Soviet state as it enters the global biocybernetic economy.

AdS Black Hole with Phantom Scalar Field

Directory of Open Access Journals (Sweden)

Limei Zhang

2017-01-01

Full Text Available We present an AdS black hole solution with Ricci flat horizon in Einstein-phantom scalar theory. The phantom scalar fields just depend on the transverse coordinates x and y, which are parameterized by the parameter α. We study the thermodynamics of the AdS phantom black hole. Although its horizon is a Ricci flat Euclidean space, we find that the thermodynamical properties of the black hole solution are qualitatively the same as those of AdS Schwarzschild black hole. Namely, there exists a minimal temperature and the large black hole is thermodynamically stable, while the smaller one is unstable, so there is a so-called Hawking-Page phase transition between the large black hole and the thermal gas solution in the AdS space-time in Poincare coordinates. We also calculate the entanglement entropy for a strip geometry dual to the AdS phantom black holes and find that the behavior of the entanglement entropy is qualitatively the same as that of the black hole thermodynamical entropy.

AdS Branes from Partial Breaking of Superconformal Symmetries

International Nuclear Information System (INIS)

Ivanov, E.A.

2005-01-01

It is shown how the static-gauge world-volume superfield actions of diverse superbranes on the AdS d+1 superbackgrounds can be systematically derived from nonlinear realizations of the appropriate AdS supersymmetries. The latter are treated as superconformal symmetries of flat Minkowski superspaces of the bosonic dimension d. Examples include the N = 1 AdS 4 supermembrane, which is associated with the 1/2 partial breaking of the OSp(1|4) supersymmetry down to the N = 1, d = 3 Poincare supersymmetry, and the T-duality related L3-brane on AdS 5 and scalar 3-brane on AdS 5 x S 1 , which are associated with two different patterns of 1/2 breaking of the SU(2, 2|1) supersymmetry. Another (closely related) topic is the AdS/CFT equivalence transformation. It maps the world-volume actions of the codimension-one AdS d+1 (super)branes onto the actions of the appropriate Minkowski (super)conformal field theories in the dimension d

The advancements in the computer and internet systems in the last decade of the 20th century produced radical changes in both internet connectivity and features available to users through which people are linked across the globe. The three most basic of these internet features that have radically shaped modern communication are, Facebook, Twitters, and the U-Tube, among others. The three are the most popular and core elements of the social media compartment of our modern internet system. Computer technology has broken the boundaries of closed societies and systems, making actions and activities in such systems open and available to the wider world. Through the internet and its core elements, repressive regimes have been exposed and activities going on in liberal societies are shared. Interestingly, Africa became the starting point for the agitation for political change, which was bolstered by the social media. The so-called “Arab Spring”, which first started in Africa through expositions of social media, saw the dismantling of three despotic and ruthless regimes in Arab North Africa, thus giving vent to agitations for an end to dictatorship and illiberality in other Arab states. The paper will examine the role of the social media in political transformation and change of dictatorial regimes in Africa and the consequences such would have on the overall political template of Africa.

Critical phenomena and chemical potential of a charged AdS black hole

Science.gov (United States)

Wei, Shao-Wen; Liang, Bin; Liu, Yu-Xiao

2017-12-01

Inspired by the interpretation of the cosmological constant from the boundary gauge theory, we here treat it as the number of colors N and its conjugate quantity as the associated chemical potential μ in the black hole side. Then the thermodynamics and the chemical potential for a five-dimensional charged AdS black hole are studied. It is found that there exists a small-large black hole phase transition of van der Waals type. The critical phenomena are investigated in the N2-μ chart. The result implies that the phase transition can occur for large number of colors N , while is forbidden for small number. This to some extent implies that the interaction of the system increases with the number. In particular, in the reduced parameter space, all the thermodynamic quantities can be rescaled with the black hole charge such that these reduced quantities are charge-independent. Then we obtain the coexistence curve and the phase diagram. The latent heat is also numerically calculated. Moreover, the heat capacity and the thermodynamic scalar are studied. The result indicates that the information of the first-order black hole phase transition is encoded in the heat capacity and scalar. However, the phase transition point cannot be directly calculated with them. Nevertheless, the critical point linked to a second-order phase transition can be determined by either the heat capacity or the scalar. In addition, we calculate the critical exponents of the heat capacity and the scalar for the saturated small and large black holes near the critical point.

Comparing Political Communication

OpenAIRE

Pfetsch, Barbara; Esser, Frank

2012-01-01

This chapter describes the maturation of comparative political communications as a sub-discipline and defines its conceptual core. It then lays out the concept of “political communication system”. At the macro-level, this model captures the patterns of interaction between media and politics as social systems; at the micro-level it captures the interactions between media and political actors as individuals or organizations. Comparative research in this tradition focuses on the structure of pol...

Religion, sex and politics: Scripting connections in Romans 1:18–32 and Wisdom 14:12–14

Directory of Open Access Journals (Sweden)

Jeremy Punt

2017-08-01

Full Text Available Ancient people envisaged a strong link between what was deemed transgressive religious activities and objectionable sexual practices. Moreover, sexual behaviour considered aberrant was deemed to upset political boundaries which should protect civic and national stability, especially when this behaviour was suspected of effeminacy. Such thinking appears to inform both Romans 1:18–32 and Wisdom of Solomon 14:12–14. Focussing on two passages from these documents, the links between religion, sexual behaviour and politics in the context of the 1st-century Roman Empire are investigated, tracing underlying ideological intersections, connections and divergences.

Hidden consequences of political efficacy: Testing an efficacy-apathy model of political mobilization.

Science.gov (United States)

Osborne, Danny; Yogeeswaran, Kumar; Sibley, Chris G

2015-10-01

Political efficacy-the belief that one can influence politics-is a key predictor of people's involvement in social movements. Political institutions that are open to change should, however, be seen as just. Thus, political efficacy may ironically undermine minority group members' support for collective action by simultaneously increasing their belief in the fairness of the system. The current study aims to examine this possibility in a national sample of Māori-New Zealand's indigenous minority population. Participants (N = 399) were Māori (Mage = 44.22; SD = 13.30) women (n = 272) and men (n = 115; unreported = 12) who completed a survey assessing their levels of (a) political efficacy, (b) system justification, and (c) support for the political mobilization of their group, as well as relevant demographic covariates. Consistent with past research, political efficacy had a positive direct effect on participants' support for the political mobilization of Māori. Nevertheless, political efficacy also had a negative indirect effect on political mobilization support via increases in system justification. These results held after controlling for participants' ethnic identification, self-efficacy, and conservatism. Our findings uncover a hidden consequence of political efficacy and show that, while believing that the political system is receptive to change predicts political mobilization, it can also undermine minorities' support for the mobilization of their group. Thus, our results uncover a previously unknown process that maintains inequality between ethnic minority and majority group members. (c) 2015 APA, all rights reserved).

Politics, Power, Poverty and Global Health: Systems and Frames

2016-01-01

Striking disparities in access to healthcare and in health outcomes are major characteristics of health across the globe. This inequitable state of global health and how it could be improved has become a highly popularized field of academic study. In a series of articles in this journal the roles of power and politics in global health have been addressed in considerable detail. Three points are added here to this debate. The first is consideration of how the use of definitions and common terms, for example ‘poverty eradication,’ can mask full exposure of the extent of rectification required, with consequent failure to understand what poverty eradication should mean, how this could be achieved and that a new definition is called for. Secondly, a criticism is offered of how the term ‘global health’ is used in a restricted manner to describe activities that focus on an anthropocentric and biomedical conception of health across the world. It is proposed that the discourse on ‘global health’ should be extended beyond conventional boundaries towards an ecocentric conception of global/planetary health in an increasingly interdependent planet characterised by a multitude of interlinked crises. Finally, it is noted that the paucity of workable strategies towards achieving greater equity in sustainable global health is not so much due to lack of understanding of, or insight into, the invisible dimensions of power, but is rather the outcome of seeking solutions from within belief systems and cognitive biases that cannot offer solutions. Hence the need for a new framing perspective for global health that could reshape our thinking and actions. PMID:27694651

Baby Skyrmions in AdS

Energy Technology Data Exchange (ETDEWEB)

Elliot-Ripley, Matthew; Winyard, Thomas [Department of Mathematical Sciences, Durham University,South Rd, Durham (United Kingdom)

2015-09-01

We study the baby Skyrme model in a pure AdS background without a mass term. The tail decays and scalings of massless radial solutions are demonstrated to take a similar form to those of the massive flat space model, with the AdS curvature playing a similar role to the flat space pion mass. We also numerically find minimal energy solutions for a range of higher topological charges and find that they form concentric ring-like solutions. Popcorn transitions (named in analogy with studies of toy models of holographic QCD) from an n layer to an n+1-layer configuration are observed at topological charges 9 and 27 and further popcorn transitions for higher charges are predicted. Finally, a point-particle approximation for the model is derived and used to successfully predict the ring structures and popcorn transitions for higher charge solitons.

2014-03-01

Full Text Available Based on Lakoff’s (2002 Strict Father and Nurturant Parent metaphors for political conservatism and liberalism respectively, two studies explored parenting styles, political ideology, and the moral orientations that might link the two. Restrictive parenting (by both mother and father predicted political conservatism, and this path was mediated by a strong Social Order orientation (Study 1 reflecting, more broadly, an inhibition-based proscriptive morality (Study 2. Political liberalism was associated with a Social Justice orientation, but was not predicted by nurturant parenting in either study. Study 1 included mothers’ reports of their own parenting, and these were correlated with the students’ responses. Findings support a restrictive moral underpinning for conservatism, but raise questions about the assumed unique association between parental nurturance and political liberalism, which is addressed in the discussion.

Wess-Zumino terms for AdS D-branes

Hatsuda, Machiko; Kamimura, Kiyoshi

2004-01-01

We show that Wess-Zumino terms for Dp branes with p>0 in the anti-de Sitter (AdS) space are given in terms of 'left-invariant' currents on the super-AdS group or the 'expanded' super-AdS group. As a result there is no topological extension of the super-AdS algebra. In the flat limit the global Lorentz rotational charges of the AdS space turn out to be brane charges of the supertranslation algebra representing the BPS mass. We also show that a D-instanton is described by the GL(1) degree of freedom in the Roiban-Siegel formalism based on the GL(4 vertical bar 4)/[Sp(4)xGL(1)]2 coset

Algebraically special solutions in AdS/CFT

International Nuclear Information System (INIS)

Freitas, Gabriel Bernardi de; Reall, Harvey S.

2014-01-01

We investigate the AdS/CFT interpretation of the class of algebraically special solutions of Einstein gravity with a negative cosmological constant. Such solutions describe a CFT living in a 2+1 dimensional time-dependent geometry that, generically, has no isometries. The algebraically special condition implies that the expectation value of the CFT energy-momentum tensor is a local function of the boundary metric. When such a spacetime is slowly varying, the fluid/gravity approximation is valid and one can read off the values of certain higher order transport coefficients. To do this, we introduce a formalism for studying conformal, relativistic fluids in 2+1 dimensions that reduces everything to the manipulation of scalar quantities.

AdS/CFT correspondence, quasinormal modes, and thermal correlators in N=4 supersymmetric Yang-Mills theory

Science.gov (United States)

Núñez, Alvaro; Starinets, Andrei O.

2003-06-01

We use the Lorentzian AdS/CFT prescription to find the poles of the retarded thermal Green’s functions of N=4 SU(N) supersymmetric Yang-Mills theory in the limit of large N and large ’t Hooft coupling. In the process, we propose a natural definition for quasinormal modes in an asymptotically AdS spacetime, with boundary conditions dictated by the AdS/CFT correspondence. The corresponding frequencies determine the dispersion laws for the quasiparticle excitations in the dual finite-temperature gauge theory. Correlation functions of operators dual to massive scalar, vector and gravitational perturbations in a five-dimensional AdS-Schwarzschild background are considered. We find asymptotic formulas for quasinormal frequencies in the massive scalar and tensor cases, and an exact expression for vector perturbations. In the long-distance, low-frequency limit we recover results of the hydrodynamic approximation to thermal Yang-Mills theory.

Political regimes, political ideology, and self-rated health in Europe: a multilevel analysis.

Science.gov (United States)

Huijts, Tim; Perkins, Jessica M; Subramanian, S V

2010-07-22

Studies on political ideology and health have found associations between individual ideology and health as well as between ecological measures of political ideology and health. Individual ideology and aggregate measures such as political regimes, however, were never examined simultaneously. Using adjusted logistic multilevel models to analyze data on individuals from 29 European countries and Israel, we found that individual ideology and political regime are independently associated with self-rated health. Individuals with rightwing ideologies report better health than leftwing individuals. Respondents from Eastern Europe and former Soviet republics report poorer health than individuals from social democratic, liberal, Christian conservative, and former Mediterranean dictatorship countries. In contrast to individual ideology and political regimes, country level aggregations of individual ideology are not related to reporting poor health. This study shows that although both individual political ideology and contextual political regime are independently associated with individuals' self-rated health, individual political ideology appears to be more strongly associated with self-rated health than political regime.

Slovenian-Croatian boundary: backgrounds of boundary-making and boundary-breaking in Istria regarding the contemporary boundary dispute

Full Text Available Boundary-making in Istria is an old undertaking. It has actually never ceasesed, not even today. Istrian peninsula has thus undergone substantial boundary shifts during the last couple of centuries (especially after the Venetian demise in 1797. But Istria carries its worldwide fame also due to one of probably the harshest disputes on the post-war European grounds – the Trieste territory dispute. In author's perspective, this dispute is one of the four main corner-stones of the current Slovenian-Croatian boundary dispute. The remaining three include the Kozler's boundary around Dragonja (Rokava River, the ungraspable notions of Austrian censuses in Istria, and the narratives of partisan settlements on military jurisdiction. However, there are other very important aspects which significantly shaped the development of the dispute, but we will focus at assessing the importance of the aforementioned ones. In this sense, the analysis of the effects of the outcome of the Trieste dispute and its implications to the contemporary interstate dispute is set forth. By unveiling its material and consequently its psychological effects upon the contemporary bilateral relations, its analyses simultaneously reveals backgrounds of never answered question, why Kozler's proposed linguistic boundary around Dragonja (Rokava River turned out to become a boundary of national character. Though nowadays disputed, there is absolutely no chance for both involved parties to substantially draw away from once decisively drawn line of a layman. Despite the fierce battle of words in Slovenian public media on whether should the interstate boundary be placed on Mirna (Quieto or Dragonja Rivers, it will be argued here that the actual choice of the Valley of Dragonja as a boundary is by all means Slovenian. The arguments are based on extensive analyses of cartographic materials, relevant literature, documents, and statistical data.

Interplay Between Politics and Sport in Political Science Theories

Directory of Open Access Journals (Sweden)

Simona Kustec Lipicer

2010-01-01

Full Text Available Times when relations between politics and sports did not exist – be it in everyday practices or within scientific research – is definitely long gone, if they ever even existed. Nevertheless, it seems today that, especially within scientific research, these relations do not receive appropriate attention in the territories of former socialist sports superpowers, being a priori denied and considered as unimportant. That is why the key motive of this article is to initiate a discussion about the relevance of knowledge and research of the relations between politics and sport from two perspectives – the existing world-wide political science research experiences gained so far and already conducted researches in the territory of former Yugoslavia. In doing so, we first theoretically define the context of sports and politics, and then with the use of the literature review method analyse their mutual connectivity in the world and, more narrowly, within the work of the scientific community in the region of former Yugoslavia. Based on the gained conclusions which confirm a tight and constant, but also often abstract and flat-rate understood interplay between both analysed phenomena, a special typology for their in-depth and political-science-focused study is delivered. It is believed that distinctions between political, polity and policy approaches to sport decisively influence the mode of their future interplay.

Adding gauge fields to Kaplan's fermions

Blum, T.; Kaerkkaeinen, L.

We experiment with adding dynamical gauge field to Kaplan (defect) fermions. In the case of U(1) gauge theory we use an inhomogeneous Higgs mechanism to restrict the 3d gauge dynamics to a planar 2d defect. In our simulations the 3d theory produce the correct 2d gauge dynamics. We measure fermion propagators with dynamical gauge fields. They posses the correct chiral structure. The fermions at the boundary of the support of the gauge field (waveguide) are non-chiral, and have a mass two times heavier than the chiral modes. Moreover, these modes cannot be excited by a source at the defect; implying that they are dynamically decoupled. We have also checked that the anomaly relation is fullfilled for the case of a smooth external gauge field. (orig.)

Private political archives

2010-12-01

Full Text Available "Private political archives" are understood by me as all acts collected intently by a private person. These acts are connected with the person's participation in political life and gathered in order to be used in public activity as the source of argumentation and information about factors and mechanisms of political processes. Private political archives of the first half of the XVI century were mainly created by royal servants, often with reference to their job duties. These duties could inspire to collect political acts for private purposes. During the reign of Sigismund Augustus, archives of gentry activists were developed to small extent and they mainly focused on parliamentary life. Private political archives were created outside the executionist movement, namely in the community gathered around the royal court. After 1572, Crown and Lithuanian magnates greatly influenced the creation of political archives. Archives of lesser gentry, scarce and poor, did not disappear completely. However, they became difficult for identification. Therefore, developmental process concerned exclusively documentary "treasure troves" created by magnates. They had the financial means and possibilities to create truly valuable political archives. The same as in the previous period the dynamisms of executionist movement was reflected in political archival documentation, now the creation of patronage system and clientele, or traditionally understood magnate oligarchy, (depending on the point of view corresponded best to archives development. The heritage of previous generations was the treasure trove of patterns and solutions. However, this trove was used selectively, on one hand giving up patterns and rights that were uncomfortable, and, on the other, giving the value of precedence to unexpected acts that gained more importance or even new content in changed political conditions. The application of interpretation principle raised interest in old acts and patterns

Drawing on a multidimensional framework, in particular, critical discourse analysis and membership categorization analysis, this paper explores the various strategies employed by political leaders, attempting to reconcile disparate perspectives in the face of increasing socio-economic inter-connection and political dependence. More often than not, it was discovered, political leaders drew upon the somewhat “illusory” notion of “international community”, turning it into a tool of persuasion and membership category. In doing so, this paper aims to illustrate how the creation of illusive categories and perceptions are intended as a means of drawing support from diverse political leaders and projecting a united front before scrutinizing press and public.

Light-cone AdS/CFT-adapted approach to AdS fields/currents, shadows, and conformal fields

Light-cone gauge formulation of fields in AdS space and conformal field theory in flat space adapted for the study of AdS/CFT correspondence is developed. Arbitrary spin mixed-symmetry fields in AdS space and arbitrary spin mixed-symmetry currents, shadows, and conformal fields in flat space are considered on an equal footing. For the massless and massive fields in AdS and the conformal fields in flat space, simple light-cone gauge actions leading to decoupled equations of motion are found. For the currents and shadows, simple expressions for all 2-point functions are also found. We demonstrate that representation of conformal algebra generators on space of currents, shadows, and conformal fields can be built in terms of spin operators entering the light-cone gauge formulation of AdS fields. This considerably simplifies the study of AdS/CFT correspondence. Light-cone gauge actions for totally symmetric arbitrary spin long conformal fields in flat space are presented. We apply our approach to the study of totally antisymmetric (one-column) and mixed-symmetry (two-column) fields in AdS space and currents, shadows, and conformal fields in flat space.

Using complexity science and negotiation theory to resolve boundary-crossing water issues

Islam, Shafiqul; Susskind, Lawrence

2018-07-01

Many water governance and management issues are complex. The complexity of these issues is related to crossing of multiple boundaries: political, social and jurisdictional, as well as physical, ecological and biogeochemical. Resolution of these issues usually requires interactions of many parties with conflicting values and interests operating across multiple boundaries and scales to make decisions. The interdependence and feedback among interacting variables, processes, actors and institutions are hard to model and difficult to forecast. Thus, decision-making related to complex water problems needs be contingent and adaptive. This paper draws on a number of ideas from complexity science and negotiation theory that may make it easier to cope with the complexities and difficulties of managing boundary crossing water disputes. It begins with the Water Diplomacy Framework that was developed and tested over the past several years. Then, it uses three key ideas from complexity science (interdependence and interconnectedness; uncertainty and feedback; emergence and adaptation) and three from negotiation theory (stakeholder identification and engagement; joint fact finding; and value creation through option generation) to show how application of these ideas can help enhance effectiveness of water management.

Effect of grain mobility on ionic conductivity of Ceria added YSZ electrolyte

International Nuclear Information System (INIS)

Gupta, Alka; Omar, Shobit; Balani, Kantesh

2012-01-01

In an effort to develop novel electrolyte materials, the present work explores the effect of grain boundary mobility on ionic conductivity of CeO 2 -YSZ electrolyte. For cubic zirconia in general, the higher the grain boundary mobility, the lower the activation energy for oxide ion migration and judicious doping can be an effective method for mobility control. The two main directions for fabricating 8 mol. % YSZs (8YSZ) with 0,5 and 10 wt % CeO 2 are being followed: (i) co doping by conventional sintering (CS, 1400 ℃, 4h holding, ∼98 % theoretical density), and (ii) nano composite approach by spark plasma sintering (SPS, 1200 ℃, 5 min holding, ∼96 % theoretical density). Phase analysis by XRD, indicates that CeO 2 forms the complete solid solution with YSZ when synthesized by CS and both solid solution and composite formation (seen as isolated ceria rich zones in YSZ matrix by EDS analysis via TEM) by SPS. The grain boundary mobility for CS samples of pure and 10%CeO 2 added YSZ are 6.69 x 10 -18 to 10.35 X 10 -18 m 3 /N/s respectively. While for SPS sintered samples of pure and 10% CeO 2 added YSZ the grain boundary mobility comes out to be ∼0.032 X 10 -18 to 0.039 X 10 18 m 3 /N/s respectively. Grain mobility does not show any marginal change with increasing ceria content, elicit that the defect concentration is nearly constant in 8YSZ and is insensitive to ceria content. Remarkable increase of grain mobility in the SPS samples is attributed to rapid grain coarsening in the nano-grains limited to shorter sintering times. As expected, grain mobility for longer-times average out the transient phase and lower the net grain mobility such as in CS samples. The enhanced mobility in CeO 2 -YSZ SPS sintered electrolytes must be due to lower cation migration energy (activation energy for oxide ion migration), promoting enhanced ionic conductivity.

Steele, John M.

The relationship between astronomy and politics is a complex but important part of understanding the practice of astronomy throughout history. This chapter explores some of the ways that astronomy, astrology, and politics have interacted, placing particular focus on the way that astronomy and astrology have been used for political purposes by both people in power and people who wish to influence a ruler's policy. Also discussed are the effects that politics has had on the development of astronomy and, in particular, upon the recording and preservation of astronomical knowledge.

Defining political community

Directory of Open Access Journals (Sweden)

Sladeček Michal M.

2002-01-01

Full Text Available This paper considers the concept of political community, its constitution and value. The starting point is that the concept of community is not sufficiently recognized in modern political theories, as well as in contemporary liberal theory. In the last two decades communitarian and republican political theory attempted to revitalize this notion. The first part of the paper elaborates on the polemics between these three theoretical orientations. The concluding part examines the possibilities and prospect for stable political community in conditions of pluralism of particular social communities and ethnocultural heterogeneity.

Guardians of the public sphere? Political scandal and the press, 1979-97.

The political scandals that beset the Conservative Party during the 1980s and 1990s constitute a valuable lens for examining two interrelated areas of study: the changing power relationship between government and press, and the changing interface between public and private in contemporary discourse. Close discursive analysis of the press coverage of these scandals--and of the libel actions that resulted from them--highlights the extent to which the Thatcher administration and the tabloid press propagated a shared moral discourse, founded on the repudiation of 'permissiveness', and a return to the ideal of the patriarchal nuclear family. This alliance transformed the way in which the Conservative message was communicated, disseminated, and indeed constituted, yet ultimately proved to be a double-edged sword. By catalysing the disintegration of the boundary between public and private in political life, and investing the press with the power to mould and configure public expectations of sexual morality, Thatcher laid the groundwork for the eventual fall of the Major administration, in the wake of a long series of financial and sexual scandals. As such, this article offers insights into a hitherto unexamined aspect of Thatcher's legacy, and the unprecedented influence of the press in late twentieth-century politics.

We consider critical gravity in three dimensions; that is, the New Massive Gravity theory formulated about Anti-de Sitter (AdS) space with the specific value of the graviton mass for which it results dual to a two-dimensional conformai field theory with vanishing central charge. As it happens with Kerr black holes in four-dimensional critical gravity, in three-dimensional critical gravity the Bañados-Teitelboim-Zanelli black holes have vanishing mass and vanishing angular momentum. However, provided suitable asymptotic conditions are chosen, the theory may also admit solutions carrying non-vanishing charges. Here, we give simple examples of exact solutions that exhibit falling-off conditions that are even weaker than those of the so-called Log-gravity. For such solutions, we define the quasilocal stress-tensor and use it to compute conserved charges. Despite the drastic deformation of AdS{sub 3} asymptotic, these solutions have finite mass and angular momentum, which are shown to be non-zero.

MAPPING CHILDREN’S POLITICS: SPATIAL STORIES, DIALOGIC RELATIONS AND POLITICAL FORMATION

Science.gov (United States)

Elwood, Sarah; Mitchell, Katharyne

2015-01-01

This article confronts a persistent challenge in research on children’s geographies and politics: the difficulty of recognizing forms of political agency and practice that by definition fall outside of existing political theory. Children are effectively “always already” positioned outside most of the structures and ideals of modernist democratic theory, such as the public sphere and abstracted notions of communicative action or “rational” speech. Recent emphases on embodied tactics of everyday life have offered important ways to recognize children’s political agency and practice. However, we argue here that a focus on spatial practices and critical knowledge alone cannot capture the full range of children’s politics, and show how representational and dialogic practices remain a critical element of their politics in everyday life. Drawing on de Certeau’s notion of spatial stories, and Bakhtin’s concept of dialogic relations, we argue that children’s representations and dialogues comprise a significant space of their political agency and formation, in which they can make and negotiate social meanings, subjectivities, and relationships. We develop these arguments with evidence from an after-school activity programme we conducted with 10–13 year olds in Seattle, Washington, in which participants explored, mapped, wrote and spoke about the spaces and experiences of their everyday lives. Within these practices, children negotiate autonomy and self-determination, and forward ideas, representations, and expressions of agreement or disagreement that are critical to their formation as political actors.

Gateway Political Behaviors: The Frequency and Consequences of Low-Cost Political Engagement on Social Media

Directory of Open Access Journals (Sweden)

Leticia Bode

2017-11-01

Full Text Available The purpose of this article is to determine to what extent engagement in easy political behaviors on social media occurs across the range of political interest, what predicts such engagement, and what effect such engagement may have on other political behaviors. It pits the idea that social media may activate the politically uninterested against the idea that social media is just another outlet for the politically interested to demonstrate their engagement. Analyzing survey data collected by the Pew Research Center, it concludes that many people, including the politically uninterested, do engage in easy political behaviors like liking and commenting on political content on social media. When they do, it can lead to greater political activity offline. However, those most likely to engage in easy political behaviors are also those who engage in harder political behaviors, offering support for both the interest and activation hypotheses.

Phases of global AdS black holes

Basu, Pallab; Krishnan, Chethan; Subramanian, P.N. Bala

2016-01-01

We study the phases of gravity coupled to a charged scalar and gauge field in an asymptotically Anti-de Sitter spacetime (AdS_4) in the grand canonical ensemble. For the conformally coupled scalar, an intricate phase diagram is charted out between the four relevant solutions: global AdS, boson star, Reissner-Nordstrom black hole and the hairy black hole. The nature of the phase diagram undergoes qualitative changes as the charge of the scalar is changed, which we discuss. We also discuss the new features that arise in the extremal limit.

Pressure and Compressibility of Conformal Field Theories from the AdS/CFT Correspondence

Directory of Open Access Journals (Sweden)

Brian P. Dolan

2016-05-01

Full Text Available The equation of state associated with N = 4 supersymmetric Yang–Mills in four dimensions, for S U ( N in the large N limit, is investigated using the AdS/CFT correspondence. An asymptotically AdS black-hole on the gravity side provides a thermal background for the Yang–Mills theory on the boundary in which the cosmological constant is equivalent to a volume. The thermodynamic variable conjugate to the cosmological constant is a pressure, and the P - V diagram of the quark-gluon plasma is studied. It is known that there is a critical point where the heat capacity diverges, and this is reflected in the isothermal compressibility. Critical exponents are derived and found to be mean field in the large N limit. The same analysis applied to three- and six-dimensional conformal field theories again yields mean field exponents associated with the compressibility at the critical point.

The paper advances an interpretation of political scandal and its place in democratic politics, taking the scandals of the ‘Watergate era’ in American politics as its evidential basis. The interpretation focuses on an aspect of political scandal that has been neglected in existing treatments, namely the politically constructed rather than epistemologically simple nature of scandalous ‘exposure’. The career of the ‘smoking gun’ in the Watergate era provides illustration. The paper goes on to r...

Arbitrating a fiction: Canadian federalism and the Nova Scotia/Newfoundland and Labrador boundary dispute

Energy Technology Data Exchange (ETDEWEB)

Baier, G. [University of British Columbia, Dept. of Political Science, Vancouver, BC(Canada); Groarke, P.

2003-09-30

The dispute between the provinces of Nova Scotia and Newfoundland and Labrador, regarding ownership of natural resources to be found in the offshore area lying between the two provinces is discussed. Constitutionally, ownership of offshore natural resources belongs to the federal government. In this instance, the intention was to share control over development and revenues with the provinces through joint management accords, however, a dispute over offshore boundary arose, which eventually resulted in an arbitration tribunal. This paper analyzes the terms of reference for the tribunal and its findings, and concludes that the tribunal process was flawed. The authors cast doubts on the appropriateness of the tribunal's role, the method by which it reached its decision, and the legality of its findings. They conclude that the tribunal merely cloaks a political decision in legal garb since there are no genuine boundaries between the provinces, and the tribunal process simply apportioned federal resources between two provinces. The authors ultimately conclude that by resorting to the tribunal process the federal minister of natural resources was able to avoid political responsibility for making an unpopular decision by relying on a pseudo-judicial body for technical recommendations, and in so doing undermined the legitimacy of the Canadian federal system by obscuring the already murky lines of accountability of the federal and provincial governments. 57 end notes.

New Massive Gravity and AdS4 Counterterms

International Nuclear Information System (INIS)

Jatkar, Dileep P.; Sinha, Aninda

2011-01-01

We show that the recently proposed Dirac-Born-Infeld extension of new massive gravity emerges naturally as a counterterm in four-dimensional anti-de Sitter space (AdS 4 ). The resulting on-shell Euclidean action is independent of the cutoff at zero temperature. We also find that the same choice of counterterm gives the usual area law for the AdS 4 Schwarzschild black hole entropy in a cutoff-independent manner. The parameter values of the resulting counterterm action correspond to a c=0 theory in the context of the duality between AdS 3 gravity and two-dimensional conformal field theory. We rewrite this theory in terms of the gauge field that is used to recast 3D gravity as a Chern-Simons theory.

Model-based estimation with boundary side information or boundary regularization

International Nuclear Information System (INIS)

Chiao, P.C.; Rogers, W.L.; Fessler, J.A.; Clinthorne, N.H.; Hero, A.O.

1994-01-01

The authors have previously developed a model-based strategy for joint estimation of myocardial perfusion and boundaries using ECT (Emission Computed Tomography). The authors have also reported difficulties with boundary estimation in low contrast and low count rate situations. In this paper, the authors propose using boundary side information (obtainable from high resolution MRI and CT images) or boundary regularization to improve both perfusion and boundary estimation in these situations. To fuse boundary side information into the emission measurements, the authors formulate a joint log-likelihood function to include auxiliary boundary measurements as well as ECT projection measurements. In addition, the authors introduce registration parameters to align auxiliary boundary measurements with ECT measurements and jointly estimate these parameters with other parameters of interest from the composite measurements. In simulated PET O-15 water myocardial perfusion studies using a simplified model, the authors show that the joint estimation improves perfusion estimation performance and gives boundary alignment accuracy of <0.5 mm even at 0.2 million counts. The authors implement boundary regularization through formulating a penalized log-likelihood function. The authors also demonstrate in simulations that simultaneous regularization of the epicardial boundary and myocardial thickness gives comparable perfusion estimation accuracy with the use of boundary side information

Antismoking Ads at the Point of Sale: The Influence of Ad Type and Context on Ad Reactions.

Efforts are underway to educate consumers about the dangers of smoking at the point of sale (POS). Research is limited about the efficacy of POS antismoking ads to guide campaign development. This study experimentally tests whether the type of antismoking ad and the context in which ads are viewed influence people's reactions to the ads. A national convenience sample of 7,812 adult current smokers and recent quitters was randomized to 1 of 39 conditions. Participants viewed one of the four types of antismoking ads (negative health consequences-graphic, negative social consequences-intended emotive, benefits of quitting-informational, benefits of quitting-graphic) in one of the three contexts (alone, next to a cigarette ad, POS tobacco display). We assessed participants' reactions to the ads, including perceived effectiveness, negative emotion, affective dissonance, and motivational reaction. Graphic ads elicited more negative emotion and affective dissonance than benefits of quitting ads. Graphic ads elicited higher perceived effectiveness and more affective dissonance than intended emotive ads. Antismoking ads fared best when viewed alone, and graphic ads were least influenced by the context in which they were viewed. These results suggest that in developing POS campaigns, it is important to consider the competitive pro-tobacco context in which antismoking ads will be viewed.

Reflexions on Frasnian and Famennian stage boundary decisions as a guide to future deliberations

Science.gov (United States)

Ziegler, W.; Sandberg, C.A.

1996-01-01

The pros and cons of the three conodont-based boundaries of the Frasnian and Famennian Stages and their corresponding GSSPs (Global Stratotype Section and Point) are evaluated in terms of current taxonomic, biostratigraphic, and sedimentologic knowledge. Two of these boundaries are based on easily identified pelagic species, which provide excellent bases for global correlation. The third, for the base of the Frasnian, is based on a neritic species, whose taxonomy has been heatedly debated. The GSSPs for these three levels are all located in the Montagne Noire of southern France, partly because of political motivation to balance GSSPs selected in other regions. All three GSSPs are at levels from which global correlations cannot be effectively accomplished without aid from other, more complete sections or without making correlations strictly on the basis of taxonomic concepts - i. e., the entry of the definitive conodont species. Future deliberating bodies may want to reconsider the species chosen to delimit the base of the Frasnian and to select better GSSPs for all three boundaries.

Municipal Added Value through Solar Power Systems in the City of Freiburg

Directory of Open Access Journals (Sweden)

Simon Funcke

2012-05-01

Full Text Available The transformation of the conventional energy system towards renewable energies has entailed an increasing decentralization of energy generation in Germany, as the production units are smaller and draw on regional potentials. This can result in positive socio-economic effects in regions where the potential is exploited. The focus of this paper lies on evaluating existing methods and developing new ones, which can be used to determine local added value through renewable energy systems. The methods were required to cover direct as well as induced municipal added value effects and to include all steps of the examined value chain. A combination of methods was tested in a case study for the solar power system value chain in the city of Freiburg (ca. 220,000 inhabitants. The added value through this sector in the year 2009 was calculated at 30.8 million euros through direct effects and 6.2 million euros through induced effects. This total municipal added value of 37 million euros can be converted into roughly 1,500 jobs within the city boundaries. Based on some conservative assumptions, these numbers should be considered as minimum values.

A dynamic acetonitrile | aqueous electrolyte phase boundary in contact with platinised Teflon working electrodes is investigated. High concentrations of salt in the aqueous phase (2 M NaCl and 0.1 M NaClO{sub 4}) ensure immiscibility and the polar nature of acetonitrile aids the formation of a well-behaved triple phase boundary reaction zone. The one-electron oxidation of tert-butylferrocene in the organic phase without intentionally added electrolyte is studied. The limiting current for the flowing triple phase boundary process is shown to be essentially volume flow rate independent. The process is accompanied by the transfer of perchlorate from the aqueous into the organic phase and the flux of anions is shown to be approximately constant along the dynamic acetonitrile | aqueous electrolyte | platinum line interface. A high rate of conversion (close to 100%) is achieved at slow volume flow rates and at longer platinum electrodes.

2017-09-01

Full Text Available Solomon Benatar’s paper “Politics, Power, Poverty and Global Health: Systems and Frames” examines the inequitable state of global health challenging readers to extend the discourse on global health beyond conventional boundaries by addressing the interconnectedness of planetary life. Our response explores existing models of international cooperation, assessing how modifying them may achieve the twin goals of ensuring healthy people and planet. First, we address why the inequality reducing post World War II European welfare model, if implemented stateby-state, is unfit for reducing global inequality and respecting environmental boundaries. Second, we argue that to advance beyond the ‘Westphalian,’ human centric thinking integral to global inequality and climate change requires challenging the logic of global economic integration and exploring the politically infeasible. In conclusion, we propose social policy focused changes to the World Trade Organisation (WTO and a Green and Social Climate Fund, financed by new global greenhouse gas charges, both of which could advance human and planetary health. Recent global political developments may offer a small window of opportunity for out of the box proposals that could be advanced by concerted and united advocacy by global health activists, environmental activists, human rights activists, and trade unions.

From boundaries to boundary work: middle managers creating inter-organizational change.

Science.gov (United States)

Oldenhof, Lieke; Stoopendaal, Annemiek; Putters, Kim

2016-11-21

Purpose In healthcare, organizational boundaries are often viewed as barriers to change. The purpose of this paper is to show how middle managers create inter-organizational change by doing boundary work: the dual act of redrawing boundaries and coordinating work in new ways. Design/methodology/approach Theoretically, the paper draws on the concept of boundary work from Science and Technology Studies. Empirically, the paper is based on an ethnographic investigation of middle managers that participate in a Dutch reform program across health, social care, and housing. Findings The findings show how middle managers create a sense of urgency for inter-organizational change by emphasizing "fragmented" service provision due to professional, sectoral, financial, and geographical boundaries. Rather than eradicating these boundaries, middle managers change the status quo gradually by redrawing composite boundaries. They use boundary objects and a boundary-transcending vocabulary emphasizing the need for societal gains that go beyond production targets of individual organizations. As a result, work is coordinated in new ways in neighborhood teams and professional expertise is being reconfigured. Research limitations/implications Since boundary workers create incremental change, it is necessary to follow their work for a longer period to assess whether boundary work contributes to paradigm change. Practical implications Organizations should pay attention to conditions for boundary work, such as legitimacy of boundary workers and the availability of boundary spaces that function as communities of practice. Originality/value By shifting the focus from boundaries to boundary work, this paper gives valuable insights into "how" boundaries are redrawn and embodied in objects and language.

Full Text Available The following study is dedicated to the process of political fundraising as a subject of political science. Through the article one can find the definition of political fundraising and American political scientists' approaches to the analysis of this process. Comparative analysis of political fundraising in the U.S.A. and Russian Federation demonstrates that its' transparency has an important impact on public's control of lobby groups and other shadow political entities.

Loops in AdS from conformal field theory

We propose and demonstrate a new use for conformal field theory (CFT) crossing equations in the context of AdS/CFT: the computation of loop amplitudes in AdS, dual to non-planar correlators in holographic CFTs. Loops in AdS are largely unexplored, mostly due to technical difficulties in direct calculations. We revisit this problem, and the dual 1 /N expansion of CFTs, in two independent ways. The first is to show how to explicitly solve the crossing equations to the first subleading order in 1 /N 2, given a leading order solution. This is done as a systematic expansion in inverse powers of the spin, to all orders. These expansions can be resummed, leading to the CFT data for finite values of the spin. Our second approach involves Mellin space. We show how the polar part of the four-point, loop-level Mellin amplitudes can be fully reconstructed from the leading-order data. The anomalous dimensions computed with both methods agree. In the case of ϕ 4 theory in AdS, our crossing solution reproduces a previous computation of the one-loop bubble diagram. We can go further, deriving the four-point scalar triangle diagram in AdS, which had never been computed. In the process, we show how to analytically derive anomalous dimensions from Mellin amplitudes with an infinite series of poles, and discuss applications to more complicated cases such as the N = 4 super-Yang-Mills theory.

Genealogy of nature conservation: a political perspective

Directory of Open Access Journals (Sweden)

Yrjo Haila

2012-03-01

Full Text Available Modern nature conservation is a product of post-Enlightenment modernity; I explore the heterogeneity of its conceptual and ideological background. The 19th century legacy comprises concern over human-caused extinctions; protests against excessive hunting and cruelty toward animals; utilitarian care for natural resources; and romantic sensibility concerning the value of nature for human health and spirituality. The 20th century added into conservation thinking increasing consciousness about human biospheric dependence; efforts to identify appropriate conservation targets; and most recently concern over the loss of biodiversity. The politics of nature conservation has taken shape within the framework of politics of nature, that is, choices vis-á-vis nature that have been made either as deliberate decisions on resource use or as side-effects of subsistence practices of various types. Because of tensions and conflicts with alternative ways of using nature, formulating realistic conservation policies has been a complicated task. Problems and uncertainties emerge: pursuing material aspirations of the current world society will necessarily bring about damage to ecological systems of the Earth. The way forward is to identify feasible alternatives in the midst of the tensions and ambiguities that arise, and to open up space for carrying through conservation initiatives.

Supersymmetric warped AdS in extended topologically massive supergravity

We determine the most general form of off-shell N=(1,1) supergravity field configurations in three dimensions by requiring that at least one off-shell Killing spinor exists. We then impose the field equations of the topologically massive off-shell supergravity and find a class of solutions whose properties crucially depend on the norm of the auxiliary vector field. These are spacelike-squashed and timelike-stretched AdS 3 for the spacelike and timelike norms, respectively. At the transition point where the norm vanishes, the solution is null warped AdS 3 . This occurs when the coefficient of the Lorentz–Chern–Simons term is related to the AdS radius by μℓ=2. We find that the spacelike-squashed AdS 3 can be modded out by a suitable discrete subgroup of the isometry group, yielding an extremal black hole solution which avoids closed timelike curves

New supersymmetric AdS4 type II vacua

International Nuclear Information System (INIS)

Tsimpis, D.

2010-01-01

We review the supersymmetric AdS 4 x w M 6 backgrounds of type IIA/IIB supergravity constructed in[1]. In type IIA the supersymmetry is N=2, and the six-dimensional internal space is locally an S 2 bundle over a four-dimensional Kaehler-Einstein base; in IIB the internal space is the direct product of a circle and a five-dimensional squashed Sasaki-Einstein manifold. These backgrounds do not contain any sources, all fluxes (including the Romans mass in IIA) are generally non-zero, and the dilaton and warp factor are non-constant. The IIA solutions include the massive deformations of the IIA reduction of the eleven-dimensional AdS 4 x Y p,q solutions, and had been predicted to exist on the basis of the AdS 4 /CFT 3 correspondence.

Instantons from geodesics in AdS moduli spaces

We investigate supergravity instantons in Euclidean AdS5 × S5/ℤk. These solutions are expected to be dual to instantons of N = 2 quiver gauge theories. On the supergravity side the (extremal) instanton solutions are neatly described by the (lightlike) geodesics on the AdS moduli space for which we find the explicit expression and compute the on-shell actions in terms of the quantised charges. The lightlike geodesics fall into two categories depending on the degree of nilpotency of the Noether charge matrix carried by the geodesic: for degree 2 the instantons preserve 8 supercharges and for degree 3 they are non-SUSY. We expect that these findings should apply to more general situations in the sense that there is a map between geodesics on moduli-spaces of Euclidean AdS vacua and instantons with holographic counterparts.

Politics, religion and gender equality in contemporary Mexico: women's sexuality and reproductive rights in a contested secular state.

Amuchástegui, Ana; Cruz, Guadalupe; Aldaz, Evelyn; Mejía, María Consuelo

2010-01-01

This article explores the complexities of the interaction between politics, religion and gender equality in contemporary Mexico, by analysing recent developments in public debate, legal changes and implementation of government policies in two areas: 1) the inclusion of emergency contraception in public health services in 2004; and 2) the decriminalisation of abortion in Mexico City in 2008, which was followed by a massive campaign to re-criminalise abortion in the federal states. Three main findings emerge from our analysis: first, that women's sexual and reproductive autonomy has become an issue of intense public debate that is being addressed by both state-public policy and society; second, that the gradual democratisation of the Mexican political system and society is forcing the Catholic Church to play by the rules of democracy; and third, that the character and nature of the Mexican (secular) state has become an arena of intense struggle within which traditional political boundaries and ideologies are being reconfigured.

Local knowledge, environmental politics, and the founding of ecology in the United States. Stephen Forbes and "The Lake as a Microcosm" (1887).

Schneider, D W

Stephen Forbes's "The Lake as a Microcosm" is one of the founding documents of the science of ecology in the United States. By tracing the connections between scientists and local fishermen underlying the research on floodplain lakes presented in "The Lake as a Microcosm," this essay shows how the birth of ecology was tied to local knowledge and the local politics of environmental transformation. Forbes and the other scientists of the Illinois Natural History Survey relied on fishermen for manual labor, expertise in catching fish, and knowledge of the natural history of the fishes. As Forbes and his colleagues worked in close contact with fishermen, they also adopted many of their political concerns over the privatization of the floodplain and became politically active in supporting their interests. The close connection between scientists and local knowledge forced the ecologists to reframe the boundaries of ecology as objective or political, pure or applied, local or scientific.

This study investigates the portrayal of traditional political cultures in West Kalimantan Province, a growing of election process. Results showed that Political life in Indonesia leads to modern political culture after experiencing a change of paradigm of political life. Political life in Indonesia leads to modern political culture after experiencing a change of paradigm of political life. Beginning Indonesia’s independence in the Old Order Phase, the politics used using the ideological paradigm, subsequent to the New Order Period used the political paradigm of unification and simplification of political parties but in practice it became the strategy of the State’s rulers to facilitate subjugating its citizens. After entering the reform era, several phenomena of political culture are displayed, some are using modern paradigm by giving women the widest possible role in political parties, and so on. Besides that there is the opposite of displaying and practicing traditional political culture, this is as it runs in West Borneo Province. The change of political culture in the modern direction is different from the political culture of the citizens in terms of who will be chosen, most West Borneo Province residents determine their political choice by using traditional patterns.

Tian, Lin-Lin; Zhao, Ning; Song, Yi-Lei; Zhu, Chun-Ling

2018-05-01

This work is devoted to perform systematic sensitivity analysis of different turbulence models and various inflow boundary conditions in predicting the wake flow behind a horizontal axis wind turbine represented by an actuator disc (AD). The tested turbulence models are the standard k-𝜀 model and the Reynolds Stress Model (RSM). A single wind turbine immersed in both uniform flows and in modeled atmospheric boundary layer (ABL) flows is studied. Simulation results are validated against the field experimental data in terms of wake velocity and turbulence intensity.

Extractive industries and political frontiers in the Amazon during the elastic rubber boom

International Nuclear Information System (INIS)

Zarate G, Carlos G

2008-01-01

The article analyzes the relationship between the extractive activity of elastic rubber, during the period between the fourth part of 19th century and the first decades of the 20 Th century, in the Amazonian frontier between Brazil, Peru and Colombia, and the process of configuration and definition of the boundaries between these countries. The central aspect of the analysis and the discussion is the questioning of the deterministic and simplistic interpretations that associate, in a mechanical way, the relationship between the kind of rubber species exploited and their production organization, the effects on the indigenous societies, and even the politic organization and delimitation of the bordering territories. It is also expected to show how these interpretations have been wrongly or instrumentally used even in the ideological field, to justify and explain the results of the bordering agreements of these countries, which conduced to establish the current Political frontiers in the Amazon

Belonging to the Land in Tura: Reforms, Migrations, and Indentity Politics in Evenkia

Full Text Available Tura is a mixed community where Evenks live alongside other indigenous groups and Russians. The establishment of Evenk autonomy, with the centre in Tura, in 1930 strengthened Evenk ethnic identity and unity through increased political and cultural representation, as well as through the integration of migrants from other regions. In the post-Soviet period, the community witnessed a population loss, a declining socio-economic situation, and the abolition of autonomy. In the long course of reforms and identity construction, the indigenous intelligentsia has manipulated the concept of belonging to the land either to stress or to erase cultural differences, and thus, to secure the access of the local elite to valuable resources. currently, the most hotly debated boundaries are those dividing Evenks into local and migrant, authentic and unauthentic, urban and rural. The paper illustrates the intricate interrelations between ethnic, indigenous, and territorial identities from an identity politics perspective.
