Integralidade do cuidado: representa es sociais das equipes de Saúde da Família do Distrito Federal Comprehensive care: social representations of Family Health teams in Distrito Federal, Brazil
Vladimir Andrei Rodrigues Arce,Maria Fátima de Sousa
Saúde e Sociedade , 2013,
Abstract: Trata-se de pesquisa qualitativa que analisou as representa es sociais dos profissionais da Estratégia Saúde da Família (ESF) do Distrito Federal-DF acerca da integralidade do cuidado. A ESF vem sendo implantada no Brasil desde 1994 como uma estratégia política para reordenar o modelo de aten o à saúde, estando atualmente em processo de amplia o no DF. Foram realizados entrevistas individuais semiestruturadas e grupo focal com gestores locais e profissionais das equipes de 11 das 15 regionais de saúde. Utilizou-se o Discurso de Sujeito Coletivo (DSC) e a teoria das Representa es Sociais para análise, com o objetivo de compreender a sociogênese da forma de pensar a partir de um olhar psicossocial sobre a realidade. Verificou-se que o cuidado é percebido como ato de solidariedade e atributo profissional, apoio às famílias em suas múltiplas necessidades e articula o de a es interdisciplinares de preven o, promo o e tratamento, visando qualidade de vida. A integralidade do cuidado permeia a no o de autonomia profissional, requer a cria o de vínculos de confian a e responsabiliza o entre profissionais e usuários, a contextualiza o da família sobre os determinantes e formas de enfrentamento dos problemas e demanda a integra o com demais servi os. O estudo demonstrou que o cuidado relaciona-se com diferentes dimens es da integralidade, refletindo potencialidades e desafios do modelo da ESF para o desenvolvimento de práticas ampliadas de saúde. Faz-se necessário que a potencialidade das rela es estabelecidas entre diferentes sujeitos no território permita a qualifica o das a es de saúde, sobretudo aquelas voltadas para a promo o. This qualitative research analyzed the social representations about comprehensive care of the health professionals who work at the teams of the Family Health Strategy (ESF) in Distrito Federal - DF, Brazil. The ESF is being implemented in Brazil since 1994 as a political strategy in order to reorganize the "model of health care", and currently is in expansion in the DF. The study was developed in 11 of 15 health regions in DF; information was gathered through individual semi-structured interviews and focal group with local managers and teams' professionals. Interviews were analyzed using the Discourse of the Collective Subject (DSC) method based on the theory of Social Representations, aiming to understand the sociogenesis of thinking, taking into account the psychosocial reality. It was found that care is understood both as an act of solidarity and a professional attribute to support families in their multiple needs; i
A práxis da Saúde Mental no ambito da Estratégia Saúde da Família: contribui??es para a constru??o de um cuidado integrado
Arce, Vladimir Andrei Rodrigues;Sousa, Maria Fátima de;Lima, Maria da Glória;
Physis: Revista de Saúde Coletiva , 2011, DOI: 10.1590/S0103-73312011000200011
Abstract: this paper, originated in a quali-quantitative study, attempted to analyze the practices of mental health in family health strategy teams from brazlandia, federal district, brazil, concerning their potential and limits for delivering integral care to people with mental distresses in primary care. interviews were conducted with the professionals who were trained in mental health. the analysis employed the method of the discourse of the collective subject. the results showed that the population has limited access to mental health care, due to the lack of structured support network. there was also low capacity to solve mental health problems in the context of fhs, since the actions developed emphasize outpatient appointments and referrals to medical admissions in hospitals, what shows both the still hegemonic biomedical conception in the practices, as the dismantling of a network to ensure integral care. these results lead to the debate of qualifications of the fhs teams in mental health, in order to recognize and enjoy the potential of the bond established between teams and users/families.
Critical Point Correlation Function for the 2D Random Coupling Ising Model
Andrei Talapov,Vladimir Dotsenko
Physics , 1993,
Abstract: High accuracy Monte Carlo simulation results for 1024*1024 Ising system with ferromagnetic impurity bonds are presented. Spin-spin correlation function at a critical point is found to be numerically very close to that of a pure system. This is not trivial since a critical temperature for the system with impurities is almost two times lower than pure Ising $T_c$. Small deviations from the pure behaviour contradict to some of the competing theories.
On nonlinearity implications and wind forcing in Hasselmann equation
Pushkarev Andrei,Zakharov Vladimir
Physics , 2015,
Abstract: We discuss several experimental and theoretical techniques historically used for Hasselmann equation wind input terms derivation. We show that recently developed ZRP technique in conjunction with high-frequency damping without spectral peak dissipation allows to reproduce more than a dozen of fetch-limited field experiments. Numerical simulation of the same Cauchy problem for different wind input terms has been performed to discuss nonlinearity implications as well as correspondence to theoretical predictions.
Phase space geometry for constrained Lagrangian systems
Vladimir Pavlov,Andrei Starinets
Physics , 1998,
Abstract: We study geometry of the phase space for finite-dimensional dynamical systems with degenerate Lagrangians. The Lagrangian and Hamiltonian constraint formalisms are treated as different local-coordinate pictures of the same invariant procedure. The invariant description is given in terms of geometrical objects associated with the structure of foliation on the phase space.
Detailed analysis of prolate quadratures and interpolation formulas
Andrei Osipov,Vladimir Rokhlin
Mathematics , 2012,
Abstract: As demonstrated by Slepian et. al. in a sequence of classical papers, prolate spheroidal wave functions (PSWFs) provide a natural and efficient tool for computing with bandlimited functions defined on an interval. As a result, PSWFs are becoming increasing popular in various areas in which such function occur - this includes physics (e.g. wave phenomena, fluid dynamics), engineering (e.g. signal processing, filter design), etc. To use PSWFs as a computational tool, one needs fast and accurate numerical algorithms for the evaluation of PSWFs and related quantities, as well as for the construction of quadratures, interpolation formulas, etc. Even though, for the last half a century, substantial progress has been made in design of such algorithms, the complexity of many of the existing algorithms, however, is at least quadratic in the band limit $c$. For example, the evaluation of the $n$th eigenvalue of the prolate integral operator requires at least $O(c^2)$ operations. Therefore, while the existing algorithms are quite satisfactory for moderate values of $c$ (e.g. $c \leq 10^3$), they tend to be relatively slow when $c$ is large (e.g. $c \geq 10^4$). In this paper, we describe several numerical algorithms for the evaluation of PSWFs and related quantities, and design a class of PSWF-based quadratures for the integration of bandlimited functions. Also, we perform detailed analysis of the related properties of PSWFs. While the analysis is somewhat involved, the resulting numerical algorithms are quite simple and efficient in practice. For example, the evaluation of the $n$th eigenvalue of the prolate integral operator requires $O(n+c)$ operations; also, the construction of related accurate quadrature rules requires $O(c)$ operations. Our results are illustrated via several numerical experiments.
On the evaluation of prolate spheroidal wave functions and associated quadrature rules

Recently, PSWFs have been becoming increasingly popular in various areas in which such functions occur - this includes physics (e.g. wave phenomena, fluid dynamics), engineering (signal processing, filter design), etc. To use PSWFs as a computational tool, one needs fast and accurate numerical algorithms for the evaluation of PSWFs and related quantities, as well as for the construction of corresponding quadrature rules, interpolation formulas, etc. During the last 15 years, substantial progress has been made in the design of such algorithms. However, many of the existing algorithms tend to be relatively slow when $c$ is large (e.g. c>10^4). In this paper, we describe several numerical algorithms for the evaluation of PSWFs and related quantities, and design a class of PSWF-based quadratures for the integration of bandlimited functions. While the analysis is somewhat involved and will be published separately, the resulting numerical algorithms are quite simple and efficient in practice. For example, the evaluation of the $n$th eigenvalue of the prolate integral operator requires $O(n+c \cdot \log c)$ operations; the construction of accurate quadrature rules for the integration (and associated interpolation) of bandlimited functions with band limit $c$ requires $O(c)$ operations. All algorithms described in this paper produce results essentially to machine precision. Our results are illustrated via several numerical experiments.
Localizations at infinity and essential spectrum of quantum Hamiltonians: I. General theory
Vladimir Georgescu,Andrei Iftimovici
Mathematics , 2005, DOI: 10.1142/S0129055X06002693
Abstract: We isolate a large class of self-adjoint operators H whose essential spectrum is determined by their behavior at large x and we give a canonical representation of their essential spectrum in terms of spectra of limits at infinity of translations of H. The configuration space is an arbitrary abelian locally compact not compact group.
Complex Curve of the Two Matrix Model and its Tau-function
Vladimir A. Kazakov,Andrei Marshakov
Physics , 2002, DOI: 10.1088/0305-4470/36/12/315
Abstract: We study the hermitean and normal two matrix models in planar approximation for an arbitrary number of eigenvalue supports. Its planar graph interpretation is given. The study reveals a general structure of the underlying analytic complex curve, different from the hyperelliptic curve of the one matrix model. The matrix model quantities are expressed through the periods of meromorphic generating differential on this curve and the partition function of the multiple support solution, as a function of filling numbers and coefficients of the matrix potential, is shown to be the quasiclassical tau-function. The relation to softly broken N=1 supersymmetric Yang-Mills theories is discussed. A general class of solvable multimatrix models with tree-like interactions is considered.
