Focalizando as Salas de Leitura Polo do Município do Rio de Janeiro, este trabalho empreende uma leitura que visa a analisar as concepções que têm sustentado a configuração destes espaços e as práticas neles desenvolvidas, dialogando com as concepções de leitura em circulação na literatura específica, enfatizando a contribuição da perspectiva discursiva para o encaminhamento das questões relativas à ruptura com o modelo de ensino tradicional, baseado na administração do sentido supostamente único. Para tanto, examina os dispositivos legais que regem as Salas de Leitura e as condições concretas de realização das práticas, buscando articular os níveis macro e micro de análise através do ciclo de políticas, formulado por Stephen Ball e colaboradores, privilegiando as relações entre os contextos de influência, da produção textual e da prática. Assume a abordagem qualitativa e, nela, o estudo de caso, ciente da impossibilidade de generalizações, com o objetivo de aprofundar as observações sistemáticas cotidianas e a interlocução constante com os professores responsáveis pela implementação da proposta, em duas escolas municipais. A descrição minuciosa dos dois contextos da prática remete a considerações acerca das reconfigurações das Salas de Leitura, seus determinantes e as ressignificações produzidas pelos sujeitos envolvidos. Na medida em que o período do trabalho de campo coincidiu com mudança significativa no contexto de influência e de produção textual, a pretensão é sistematizar elementos para a análise dos modos pelos quais esta chega ao contexto da prática e das possibilidades de reconfiguração do espaço das Salas de Leitura.

Some protected special spaces on behalf of fundamental rights to the environment and the housing at the city of Natal are fragile by facing actions and attempts to suppress and changing (or omission in the implementation) of standards in furtherance of those rights at the local level, which seems to reflect a situation that goes beyond the context of the city. Based on integrated approach of the housing rights and the environment and its protection of special spaces on the field of fundamental rights, the thesis seeks to understand the weaknesses that affect the legal state duty under the realization/implementation of fundamental rights to the environment and housing in cities, focusing on the issues of flexibility of the founding legislation of special spaces to the detriment of the attributes they protected and the lack of implementation of the legal system that allows their effectiveness. So, it looks initially to understand the environment and housing rights and their special protected areas in the brazilian legal system, looking forward the evolution of its legal protection, as well as the weaknesses that emerge in the field of their effectiveness. Analyzing the trajectory of the environment and housing rights and their special protected areas in Natal, considering its standards, attributes, protection indicators, weaknesses and negative evidence within its legal protections and their enforcement by state entity, this thesis proposes to verify the existence of forms to confronting the weaknesses founded in the maintenance of legal protection and its implementation. At this point it discusses the legal basis and safeguard instruments of protection, especially within the juridical field, as part of a (re)discussion about issues of legislative and administrative discretion in the face of objective legal state duty to realization/implementation of fundamental rights in the urban space. With all these issues together the thesis does not ignore the scenario where the dividing line between public and private (economic) are becoming ever more tenuous in the field of state action and where the city stands as a special commodity to the reproduction of real estate, according to the interests of capitalist logic

The images of Hermite and Laguerre-Sobolev spaces under the Hermite and special Hermite semigroups (respectively) are characterized. These are used to characterize the image of Schwartz class of rapidly decreasing functions f on R-n and C-n under these semigroups. The image of the space of tempered distributions is also considered and a Paley-Wiener theorem for the windowed (short-time) Fourier transform is proved.

We study the boundedness of Toeplitz operators on Segal-Bargmann spaces in various contexts. Using Gutzmer's formula as the main tool we identify symbols for which the Toeplitz operators correspond to Fourier multipliers on the underlying groups. The spaces considered include Fock spaces, Hermite and twisted Bergman spaces and Segal-Bargmann spaces associated to Riemannian symmetric spaces of compact type.

We extend the Weyl-Wigner transformation to those particular degrees of freedom described by a finite number of states using a technique of constructing operator bases developed by Schwinger. Discrete transformation kernels are presented instead of continuous coordinate-momentum pair system and systems such as the one-dimensional canonical continuous coordinate-momentum pair system and the two-dimensional rotation system are described by special limits. Expressions are explicitly given for the spin one-half case. © 1988.

This paper describes a concept for supporting distributed hands-on collaboration through interaction design for the physical and the digital workspace. The Blended Interaction Spaces concept creates distributed work environments in which collaborating parties all feel that they are present “here” rather than “there”. We describe thinking and inspirations behind the Blended Interaction Spaces concept, and summarize findings from fieldwork activities informing our design. We then exemplify the Blended Interaction Spaces concept through a prototype implementation of one of four concepts.

The object of this dissertation is to study globally defined bounded p-harmonic functions on Cartan-Hadamard manifolds and Gromov hyperbolic metric measure spaces. Such functions are constructed by solving the so called Dirichlet problem at infinity. This problem is to find a p-harmonic function on the space that extends continuously to the boundary at inifinity and obtains given boundary values there. The dissertation consists of an overview and three published research articles. In the first article the Dirichlet problem at infinity is considered for more general A-harmonic functions on Cartan-Hadamard manifolds. In the special case of two dimensions the Dirichlet problem at infinity is solved by only assuming that the sectional curvature has a certain upper bound. A sharpness result is proved for this upper bound. In the second article the Dirichlet problem at infinity is solved for p-harmonic functions on Cartan-Hadamard manifolds under the assumption that the sectional curvature is bounded outside a compact set from above and from below by functions that depend on the distance to a fixed point. The curvature bounds allow examples of quadratic decay and examples of exponential growth. In the final article a generalization of the Dirichlet problem at infinity for p-harmonic functions is considered on Gromov hyperbolic metric measure spaces. Existence and uniqueness results are proved and Cartan-Hadamard manifolds are considered as an application.

The need for special education (SE) is increasing. The majority of those whose problems are due to neurodevelopmental disorders have no specific aetiology. The aim of this study was to evaluate the contribution of prenatal and perinatal factors and factors associated with growth and development to later need for full-time SE and to assess joint structural and volumetric brain alterations among subjects with unexplained, familial need for SE. A random sample of 900 subjects in full-time SE allocated into three levels of neurodevelopmental problems and 301 controls in mainstream education (ME) provided data on socioeconomic factors, pregnancy, delivery, growth, and development. Of those, 119 subjects belonging to a sibling-pair in full-time SE with unexplained aetiology and 43 controls in ME underwent brain magnetic resonance imaging (MRI). Analyses of structural brain alterations and midsagittal area and diameter measurements were made. Voxel-based morphometry (VBM) analysis provided detailed information on regional grey matter, white matter, and cerebrospinal fluid (CSF) volume differences. Father’s age ≥ 40 years, low birth weight, male sex, and lower socio-economic status all increased the probability of SE placement. At age 1 year, one standard deviation score decrease in height raised the probability of SE placement by 40% and in head circumference by 28%. At infancy, the gross motor milestones differentiated the children. From age 18 months, the fine motor milestones and those related to speech and social skills became more important. Brain MRI revealed no specific aetiology for subjects in SE. However, they had more often ≥ 3 abnormal findings in MRIs (thin corpus callosum and enlarged cerebral and cerebellar CSF spaces). In VBM, subjects in full-time SE had smaller global white matter, CSF, and total brain volumes than controls. Compared with controls, subjects with intellectual disabilities had regional volume alterations (greater grey matter volumes in the anterior cingulate cortex bilaterally, smaller grey matter volume in left thalamus and left cerebellar hemisphere, greater white matter volume in the left fronto-parietal region, and smaller white matter volumes bilaterally in the posterior limbs of the internal capsules). In conclusion, the epidemiological studies emphasized several factors that increased the probability of SE placement, useful as a framework for interventional studies. The global and regional brain MRI findings provide an interesting basis for future investigations of learning-related brain structures in young subjects with cognitive impairments or intellectual disabilities of unexplained, familial aetiology.

In the study of holomorphic maps, the term ``rigidity'' refers to certain types of results that give us very specific information about a general class of holomorphic maps owing to the geometry of their domains or target spaces. Under this theme, we begin by studying when, given two compact connected complex manifolds X and Y, a degree-one holomorphic map f :Y -> X is a biholomorphism. Given that the real manifolds underlying X and Y are diffeomorphic, we provide a condition under which f is a biholomorphism. Using this result, we deduce a rigidity result for holomorphic self-maps of the total space of a holomorphic fiber space. Lastly, we consider products X = X-1 x X-2 and Y = Y-1 x Y-2 of compact connected complex manifolds. When X-1 is a Riemann surface of genus >= 2, we show that any non-constant holomorphic map F:Y -> X is of a special form.
