A virtuous circle: the positive evaluation phenomenon in arts audience research

Arts impact evaluation is the subject of widespread criticism, ranging from a detailed critique of methodology to a wholesale rejection of the very purpose of the endeavour. In particular, it is often identified that audience evaluations are almost always positive. Yet whatever the critique, arts impact evaluation is becoming more and not less prevalent as a condition of public and philanthropic funding. This article explores both the methodologicaland conceptual problems that contribute to the perceived positive characterof social impact research, in two parts: (1) an investigation of the critical literature on audience evaluation, particularly in relation to the argument that evaluation is inevitably positive and as such leads to a confusion between the goals of evaluation and arts advocacy; (2) a reflection on our practices as audience researchers in the performing arts and the practical factors that contribute to the dominance of the positive in audience evaluation.

Signatures of doubly charged Higgs in the SU(3)(L) circle times U(1)(N) model at the CERN LHC

The scalar sector of the simplest version of the 3-3-1 electroweak model is constructed with three Higgs triplets only. We show that a relation involving two of the constants of the model, two vacuum expectation values of the neutral scalars, and the mass of the doubly charged Higgs boson leads to important information concerning the signals of this scalar particle.

Neutral Higgs bosons in the SU(3)(L)circle times U(1)(N) model

The SU(3)(L)circle times U(1)(N) electroweak model predicts new Higgs bosons beyond the one of the standard model. In this work we investigate the signature and production of neutral SU(3)(L)circle times U(1)(N) Higgs bosons in the e(-)e(+) Next Linear Collider and in the CERN Linear Collider . We compute the branching ratios of two of the SU(3)(L)circle times U(1)(N) neutral Higgs bosons and study the possibility to detect them and the Z' extra neutral boson of the model.

Slogans políticos em campanhas eleitorais no Rio Grande do Norte: a mídia na disputa ideológica.

To the observe the periods of electoral campaigns, we can realize sharply the abundance of political propaganda that announces the candidates, their campaign record, their proposed and everything that can carry them to the victory in the urns. The propaganda is today an essential tool in the votes dispute, in consequence of this, there is, in Brazil, the increasing participation of the Politics Parties in seminars of electoral marketing. They are varied strategies of the media used in the divulging of the candidacies, among them the slogan. Instigated by the explicit relation media/political, this work intends to investigate the ideologies (values) announced by the slogans of political propaganda that circulated in electoral periods. Thus, we base on the theory of the Circle of Bakhtin, who considers the statement as unit of the verbal communication, and that conceives the language as phenomenon dialogical, and, too, in the conceptions of alien words, social voices and dialogical relations formulated by the referred theory. We use, for better to comprehend, the slogan as strategy mediatic, of the classical study done by Olivier Reboul concerning the slogan; and, like starting point of a conception about ideology, studied John Thompson to comprehends the ideological phenomenon. Our corpus it constitutes of 14 political slogans announced in the campaigns for mayor of the cities in Natal and Mossoró, both located in Rio Grande do Norte s state, Brazil, in 1996, 2000 and 2004. For the analysis of these slogans, we consider the social-historical context in which were announced, being contemplated the linguistic and discursive aspect, according to the following methodological order: the identification of alien words (interdiscours); the social voices and the kinds dialogical relations established; and, finally, the ideology announced by the statement. This way, we can arrive to the conclusion that in the electoral context occurs a true ideologies war , in other words, in the political game of an electoral campaign, the slogans announces different values, which vary in several factors function, for example, the historicity, the subject that enunciates, the discursive positionings.

Práticas discursivas e relações afetivas na contemporaneidade: o caso dos verbos ficar e namorar no contexto do vestibular da UFRN

This work is inserted to Applied Linguistic studies, concerned to the understanding that language is a social practice, bringing a qualitative research, discussing essential aspects that involve the subject and his/her discursive practice: signification and valuation. Due to this, we have elected as subject study, the sense and values attributed to the verbs make out and date searched on the articles written in the Vestibular 2005 process promoted by the Universidade Federal do Rio Grande do Norte (UFRN), that had the following instruction: In a relationship, is it better make out , just date , or, both, make out and date ? This research is based on the Circle of Bakhtin s dialogic theory, as well as in the notions of instability in the affective relationships nowadays and in the individualization and multiplicity of contemporaneous subjectivity. Those papers are important to analyze the meaning and values that the verbs make out and date present, nowadays, as expressions of an affective relationship and how this situation can interfere in the positions of subjectivity in a formal instance as a vestibular. Those textual productions reflect those relationships, confronting temporary ones, whose discuss is marked, in general, by social voices that evaluate to make out negatively and to date positively

A construção estilística das identidades poéticas da cidade de Natal: um olhar bakhtiniano

The purpose of this work is to bring forward cultural identities of the city of Natal that are built upon representations contained in the work of Twentieth-Century Potiguar1 poets. We started out with the premise that the urban tissue owes its formation to the effect of the feelings produced and to the individuals that give shape to them, thus causing the city to abound with feelings and meanings that are relevant for both society and the individual. As cities and their identities may be studied and interpreted from different viewpoints, we have used in this study poetic discourse that functions as a memory to the city and takes shape out of a set of historically established social practices. Our research is situated within the area of Applied Linguistics, an area of knowledge focused mainly in language that is increasingly expanding its investigation limits in an interdisciplinary way. Therefore, this study is based on a social and historical model of language, with language construed as a discourse practice (Bakhtin and Circle), and presents an interface with cultural studies (Hall, Canclini), taking into account the fact that culture builds up values and brings forth differences in respect of the conditions under which such values and differences are produced. In this sense, we have tried to ―listen‖ to what the poets say, by understanding and interpreting the meanings produced by their discourse, in order to identify the formation of the identities of the city that arise out of distinct points of view and diverse stylistic marks. Analysis of these poetic utterances lead to multifold cultural identities of the city, ranging from a naive and multicolored Natal to a city that builds itself on its characters and on to an insurgent, usurped Natal

Naturally light invisible axion and local Z(13)circle times Z(3) symmetries

We show that by imposing local Z(13)circle timesZ(3) symmetries in an SU(2)circle timesU(1) electroweak model we can implement an invisible axion in such a way that (i) the Peccei-Quinn symmetry is an automatic symmetry of the classical Lagrangian, and (ii) the axion is protected from semiclassical gravitational effects. In order to be able to implement such a large discrete symmetry, and at the same time allow a general mixing in each charge sector, we introduce right-handed neutrinos and enlarge the scalar sector of the model. The domain wall problem is briefly considered.

SU(5)circle times Z(13) grand unification model

We propose an SU(5) grand unified model with an invisible axion and the unification of the three coupling constants which is in agreement with the values, at M(Z), of alpha, alpha(s), and sin(2)theta(W). A discrete, anomalous, Z(13) symmetry implies that the Peccei-Quinn symmetry is an automatic symmetry of the classical Lagrangian protecting, at the same time, the invisible axion against possible semiclassical gravity effects. Although the unification scale is of the order of the Peccei-Quinn scale the proton is stabilized by the fact that in this model the standard model fields form the SU(5) multiplets completed by new exotic fields and, also, because it is protected by the Z(13) symmetry.

Closing the SU(3)(L)circle times U(1)(X) symmetry at the electroweak scale

We show that some models with SU(3)(C)circle times SU(3)(L)circle times U(1)(X) gauge symmetry can be realized at the electroweak scale and that this is a consequence of an approximate global SU(2)(L+R) symmetry. This symmetry implies a condition among the vacuum expectation value of one of the neutral Higgs scalars, the U(1)(X)'s coupling constant, g(X), the sine of the weak mixing angle sin theta(W), and the mass of the W boson, M-W. In the limit in which this symmetry is valid it avoids the tree level mixing of the Z boson of the standard model with the extra Z(') boson. We have verified that the oblique T parameter is within the allowed range indicating that the radiative corrections that induce such a mixing at the 1-loop level are small. We also show that a SU(3)(L+R) custodial symmetry implies that in some of the models we have to include sterile (singlets of the 3-3-1 symmetry) right-handed neutrinos with Majorana masses, since the seesaw mechanism is mandatory to obtain light active neutrinos. Moreover, the approximate SU(2)(L+R)subset of SU(3)(L+R) symmetry implies that the extra nonstandard particles of these 3-3-1 models can be considerably lighter than it had been thought before so that new physics can be really just around the corner.

A statistical law for multiplicities of SU(3) irreps (lambda, mu) in the plethysm {eta} circle times(3) {m} -> (lambda, mu)

A statistical law for the multiplicities of the SU(3) irreps (lambda, mu) in the reduction of totally symmetric irreducible representations {m} of U(N), N = (eta + 1) (eta + 2)/2 with eta being the three-dimensional oscillator major shell quantum number, is derived in terms of the quadratic and cubic invariants of SU(3), by determining the first three terms of an asymptotic expansion for the multiplicities. To this end, the bivariate Edgeworth expansion known in statistics is used. Simple formulae, in terms of m and eta, for all the parameters in the expansion are derived. Numerical tests with large m and eta = 4, 5 and 6 show good agreement with the statistical formula for the SU(3) multiplicities.

Fixed points on torus fiber bundles over the circle

The main purpose of this work is to study fixed points of fiber-preserving maps over the circle S-1 for spaces which axe fibrations over S-1 and the fiber is the torus T. For the case where the fiber is a surface with nonpositive Euler characteristic, we establish general algebraic conditions, in terms of the fundamental group and the induced homomorphism, for the existence of a deformation of a map over S-1 to a fixed point, free map. For the case where the fiber is a torus, we classify all maps over S-1 which can be deformed fiberwise to a fixed point free map.
