Authors: Noack Segovia Jessica , Inzunza Noack Javiera , Sánchez López Antonio Manuel , Levet Hernández María Cristina , Menor  Rodríguez María José , Aguilar-Cordero María José 
Published: January 2017

Introducción: los pacientes sometidos a cirugía bariátrica disminuyen de peso por una mala absorción de los alimentos o por la disminución de la ingesta calórica, pero mantienen sus hábitos de vida previos a la intervención. La actividad física es importante para aumentar los beneficios de la cirugía bariátrica y disminuir así el riesgo de enfermedades cardiovasculares y metabólicas, así como la prevención del efecto rebote.Objetivo: analizar de forma objetiva el nivel de actividad física de los pacientes operados de cirugía bariátrica.Métodos: se ha llevado a cabo una búsqueda sistemática y se han seleccionado 10 artículos específicos sobre el tema, siguiendo las directrices PRISMA.Resultados: la mayoría de los estudios realizados a los pacientes sometidos a cirugía bariátrica se efectúan con instrumentos de autoevaluación subjetivos. En esta revisión se han seleccionado 10 trabajos científicos que, además, utilizaron la acelerometría como método objetivo para medir la actividad física.Conclusiones: los pacientes sometidos a cirugía bariátrica aumentan o mantienen sus comportamientos sedentarios, lo que no concuerda con su percepción de la actividad física que afirman llevar a cabo. Es importante valorar no solo el comportamiento sedentario, sino también qué actividad sedentaria tiene mayor prevalencia. Todo ello, para establecer estrategias de intervención frente a esa forma de actuar, disminuyendo así el riesgo de enfermedades cardiovasculares y metabólicas y evitar el efecto rebote.

Transformações da metrópole contemporânea: novas dinâmicas espaciais, esfera da vida pública e sistema de espaços livres
Authors: Benfatti Denio M. , Queiroga Eugenio F. , Silva Jonathas M. P. 
Published: January 2017

O trabalho reflete sobre as novas formas de expansão e crescimento metropolitano, associando-as a transformações igualmente importantes na esfera da vida pública. A expressão cotidiana desse processo de expansão e crescimento se deixa transparecer a partir de dois movimentos complementares. De um lado, o aumento em número e extensão dos deslocamentos cotidianos de uma comunidade a outra em um mesmo ambiente metropolitano. De outro, reflete as transformações resultantes do modo de vida metropolitano: horários variáveis e flexíveis, individualização das práticas de produção e consumo. Temos como objeto desta reflexão a Metrópole de Campinas como parte do território metropolitanizado que ocorre no entorno da capital paulista. Nossa hipótese é que essas transformações não se restringem anovas denominações de um processo ampliado de urbanização, mas que essas transformações têm engendrado novos padrões e espaços de sociabilidade e, mais do que isso, um modo de vida e produção específicos. Nesta reflexão, interessa-nos mostrar como essa nova dinâmica afeta a esfera da vida pública e a definição e constituição dos sistemas de espaços livres. Palavras-chave: megalópole; urbanização fragmentada; esfera da vida pública; espaço público; sistema de espaços livres. Abstract: The paper reflects on new forms of metropolitan growth and expansion, associating them with equally significant changes in the sphere of public life. The daily expression of this process of expansion and growth can be perceived through two complementary movements. On the one hand, the growth in number and extent of daily displacements between communities within the same metropolitan area. On the other, reflecting changes in the metropolitan way of life, flexible schedules and individualization of production and consumption practices. Our focus is the metropolis of Campinas as part of the metropolization process that occurs in the vicinity of the capital – São Paulo. Our hypothesis is that these transformations are not restricted to new names for an extended process of urbanization, but that they have generated new patterns and spaces of sociability, and more than that, they have generated a specific ways of life and production. In this reflection, we are interested in showing how this new dynamic affects the sphere of public life and in discussing the definition and constitution of open space systems. Keywords: megalopolis; fragmented urbanization; public life sphere; public space; open space system.
Preservação ambiental no contexto urbano: cidade e natureza na Ilha de Santa Catarina
Authors: Reis Almir Francisco 
Published: January 2017

A Ilha de Santa Catarina, onde se situa a maior parte do município de Florianópolis, no sul do Brasil, tem cerca de 42% de seu território enquadrado como Área de Preservação Permanente, índice extremamente elevado, talvez único no país. Estas áreas constituem barreiras ao processo de ocupação, caracterizando de modo marcante o tecido descontínuo da cidade, apesar da intensidade das transformações por que vêm passando, a partir do desenvolvimento urbano-turístico. O presente trabalho, tendo por base aportes colocados pelo paradigma ambiental e a busca por uma cidade articulada por uma rede de espaços livres públicos densa e carregada de urbanidade, faz uma leitura histórica desse processo. Analisa os impactos sobre ecossistemas costeiros e reflete sobre possibilidades e limitações das áreas de preservação ambiental no contexto urbano. Palavras-chave: preservação ambiental; crescimento urbano-turístico; projeto urbano; Ilha de Santa Catarina; Florianópolis. Abstract: Santa Catarina Island, which is a major part of the municipality of Florianópolis, has about 42% of its territory framed as Permanent Preservation Area, a very high rate, perhaps unique in Brazil. Despite the intensity of the contemporary urban growth processes in the island, these areas constitute barriers to the urban occupation process and strongly characterize the discontinuous fabric of the city. Based on environmental paradigms and searching for a city articulated by a network of public open spaces, the paper makes ahistorical reading of this process. It analyzes the impacts of urban and tourism growth on the coastal ecosystems and reflects on the possibilities and limitations of environmental preservation areas in the urban context. Keywords: environmental preservation; urban and tourism growth; urban design; Santa Catarina Island; Florianópolis.
A avaliação de políticas públicas como factor de aprendizagem, inovação institucional e cidadania: o caso da Política de Ordenamento do Território em Portugal
Authors: Ferrão João , Mourato João 
Published: January 2017

A avaliação de políticas públicas em Portugal tem cerca de duas décadas e nasceu por imposição externa (sobretudo financiamento e adopção de leis da União Europeia/UE). Não sendo o ordenamento do território uma competência formal da UE, a avaliação teve, neste caso, um início particular. Entretanto, verificou-se o sucessivo alargamento das suas componentes: avaliação de conformidade, avaliação preventiva de impactes, avaliação de dinâmicas territoriais, e avaliação dos processos e das práticas de ordenamento do território. Esta evolução traduz a paradoxal crescente “europeização” de uma política fora das competências da UE, mas também a emergência de novos paradigmas de avaliação e de ordenamento do território. Este artigo procura, a partir do caso português, contribuir para o debate sobreo papel da avaliação de políticas públicas como factor de mudança cultural das organizações, das comunidades profissionais e dos cidadãos em um contexto de crescente contestação da visão moderna e racionalista de Estado. Palavras-chave: avaliação de políticas públicas; ordenamento do território; aprendizagem; inovação institucional; mudança cultural; Portugal. Abstract: Public policy evaluation in Portugal is two decades old and arose as a response to external demands (European Union funding or legal requirements). Evaluation in spatial planning, not a formal EU competency, followed its own particular evolutive course specially comparing to other policies more exposed to normative exogenous factors. Throughout its development its aims become broader, from a simple assessment of policy conformity to a pre-emptive impact assessment and later to an evaluation of territorial dynamics, and planning processes and practices. This reflects the paradoxical Europeanisation of a policy outside the scope of EU competencies and the rise of new evaluation and spatial planning paradigms. By examining the Portuguese case, this paper contributes to the debate of the role of public policy evaluation as a factor for culture change in organisations, epistemic communities and citizens against the backdrop of a growing dispute of the modern and rationalist idea of State. Keywords: public policy evaluation; spatial planning; policy-learning; institutional innovation; culture change; Portugal.
Apropriação e ordenamento territorial na zona costeira no estado do Rio de Janeiro: grandes corporações ou as políticas públicas?
Authors: Gusmão Paulo 
Published: January 2017

O presente artigo reproduz aproximadamente uma apresentação feita pelo autor como participante da mesa-redonda A Urbanização do Litoral: Formas de Apropriação do Território organizada pela Anpur na 62ª Reunião Anual da SBPC, realizada em 2010, em Natal, RN. Assim como no caso da exposição, o propósito deste texto é o de fazer provocações acercada influência (gritante) das grandes corporações no processo de (re)ordenamento do território brasileiro e enfatizar o papel (até aqui acessório) das políticas públicas nesse processo. Visando dar foco a tais provocações, é analisado o caso da zona costeira do estado do Rio de Janeiro, mais especificamente o trecho sob a influência do Porto de Itaguaí, localizado na baía de Sepetiba. Palavras-chave: desenvolvimento e ordenamento territorial; zona costeira; cidades e regiões portuárias; políticas públicas; grandes corporações. Abstract: The purpose of this paper is to discuss the increasing influence of some corporations in the reorganization process of the Brazilian territory, emphasizing the role (up to this moment, secondary) of the public policies in this process. Focusing on this discussion, the coastal zone of the State of Rio de Janeiro is analyzed, more specifically the area under the influence of the Itaguaí harbor. Considering the new and unusual context of investments which takes place in the State of Rio de Janeiro, some elements that should take part of an agenda for the management of the space under influence of this important port are discussed. Keywords: territorial development and planning; coastal zone; port cities and regions; public policy, corporations.
Das cooperativas autofinanciadas às construtoras e incorporadoras de capital aberto: a ampliação do mercado habitacional
Authors: Castro Carolina Maria Pozzi de , Shimbo Lúcia Zanin 
Published: January 2017

Este artigo analisa as principais alterações e permanências que ocorreram na produção habitacional voltada para os estratos médio e médio-baixo da população, promovida pelas cooperativas autofinanciadas da década de 1990 e pelas empresas construtoras e incorporadoras de capital aberto dos anos 2000 na Região Metropolitana de São Paulo (RMSP). Em especial, enfatizamos algumas questões relacionadas ao padrão de lançamentos residenciais, à estrutura produtiva e de financiamento e ao impacto dessa produção no conjunto da dinâmica imobiliária metropolitana. Partimos do argumento de que a formação de um padrão econômico, inicialmente proposto pelas cooperativas autofinanciadas e, posteriormente, potencializado pelas empresas financeirizadas com forte apoio estatal, tornou-se fundamental para a consolidação de um mercado habitacional e para a elevação da atividade imobiliária em períodos recentes. Palavras-chave: habitação; mercado habitacional; política habitacional; cooperativas; autofinanciamento; empresas construtoras; capital financeiro. Abstract: This paper analyzes the main changes and continuities that have occurred in housing production towards the middle strata of the population, promoted by the self-financing cooperatives of the 1990s and by the construction companies and developers that have opened their capital in the 2000s, in the Metropolitan Region of São Paulo. In particular, we emphasize some questions related to the pattern of residential launches, the production structure and financing and the impact of this production on the dynamic of real estate throughout the metropolitan area. We argue that the making of an economic standard, originally proposed by cooperatives, was later potentiated by the financialized companies with strong government support. This process became crucial to the consolidation of the housing market and to the rising of real estate dynamics in recent periods. Keywords: planning; socio-spatial dialectics; modernity; social space.
Quantum melting of a two-dimensional Wigner crystal
Authors: Dolgopolov V T 
Published: January 2017

Abstract
The paper reviews theoretical predictions about the behavior of two-dimensional low-density electron systems at nearly absolute zero temperatures, including the formation of an electron (Wigner) crystal, crystal melting at a critical electron density, and transitions between crystal modifications in more complex (for example, two-layer) systems. The paper presents experimental results obtained from real two-dimensional systems in which the nonconducting (solid) state of the electronic system with indications of collective localization is actually realized. Experimental methods for detecting a quantum liquid–solid phase interface are discussed.

Published: January 2017

Background Clinical practice guidelines aim to reduce the rates of peritoneal dialysis (PD)-related infections, a common complication of PD in end-stage kidney disease patients. We describe the clinical practices used by Australian and New Zealand nephrologists to prevent PD-related infections in PD patients. Methods A survey of PD practices in relation to the use of antibiotic and antifungal prophylaxis in PD patients was conducted of practicing nephrologists identified via the Australia and New Zealand Society of Nephrology (ANZSN) membership in 2013. Results Of 333 nephrologists approached, 133 (39.9%) participated. Overall, 127 (95.5%) nephrologists prescribed antibiotics at the time of Tenckhoff catheter insertion, 85 (63.9%) routinely screened for nasal S. aureus carriage, with 76 (88.4%) reporting they treated S. aureus carriers with mupirocin ointment. Following Tenckhoff catheter insertion, 79 (59.4%) prescribed mupirocin ointment at the exit site or intranasally, and 93 (69.9%) nephrologists routinely prescribed a course of oral antifungal agent whenever their PD patients were given a course of antibiotics. Conclusions Although the majority of nephrologists prescribe antibiotics at the time of Tenckhoff catheter insertion, less than 70% routinely prescribe mupirocin ointment and/or prophylactic antifungal therapy. This variation in practice in Australia and New Zealand may contribute to the disparity in PD-related infection rates that is seen between units.
CALIBRATION OF THE EDGES HIGH-BAND RECEIVER TO OBSERVE THE GLOBAL 21 cm SIGNATURE FROM THE EPOCH OF REIONIZATION
Authors: Monsalve Raul A. , Rogers Alan E. E. , Bowman Judd D. , Mozdzen Thomas J. 
Published: January 2017

ABSTRACT
The EDGES High-Band experiment aims to detect the sky-average brightness temperature of the 21 cm signal from the epoch of reionization in the redshift range

. To probe this redshifted signal, EDGES High-Band conducts single-antenna measurements in the frequency range 90–190 MHz from the Murchison Radio-astronomy Observatory in Western Australia. In this paper, we describe the current strategy for calibration of the EDGES High-Band receiver and report calibration results for the instrument used in the 2015–2016 observational campaign. We propagate uncertainties in the receiver calibration measurements to the antenna temperature using a Monte Carlo approach. We define a performance objective of 1 mK residual rms after modeling foreground subtraction from a fiducial temperature spectrum using a five-term polynomial. Most of the calibration uncertainties yield residuals of 1 mK or less at

confidence. However, current uncertainties in the antenna and receiver reflection coefficients can lead to residuals of up to 20 mK even in low-foreground sky regions. These dominant residuals could be reduced by (1) improving the accuracy in reflection measurements, especially their phase, (2) improving the impedance match at the antenna-receiver interface, and (3) decreasing the changes with frequency of the antenna reflection phase.
FLUORINE IN THE SOLAR NEIGHBORHOOD: NO EVIDENCE FOR THE NEUTRINO PROCESS

Published: January 2017

Abstract
Asymptotic giant branch (AGB) stars are known to produce “cosmic” fluorine, but it is uncertain whether these stars are the main producers of fluorine in the solar neighborhood or if any of the other proposed formation sites, Type II supernovae (SNe II) and/or Wolf-Rayet (W-R) stars, are more important. Recent articles have proposed both AGB stars and SNe II as the dominant sources of fluorine in the solar neighborhood. In this paper we set out to determine the fluorine abundance in a sample of 49 nearby, bright K giants for which we previously have determined the stellar parameters, as well as alpha abundances homogeneously from optical high-resolution spectra. The fluorine abundance is determined from a 2.3 μm HF molecular line observed with the spectrometer Phoenix. We compare the fluorine abundances with those of alpha-elements mainly produced in SNe II and find that fluorine and the alpha-elements do not evolve in lockstep, ruling out SNe II as the dominating producers of fluorine in the solar neighborhood. Furthermore, we find a secondary behavior of fluorine with respect to oxygen, which is another evidence against the SNe II playing a large role in the production of fluorine in the solar neighborhood. This secondary behavior of fluorine will put new constraints on stellar models of the other two suggested production sites: AGB stars and W-R stars.
A ROTATIONALLY POWERED MAGNETAR NEBULA AROUND SWIFT J1834.9–0846
Authors: Torres Diego F. 
Published: January 2017

Abstract
A wind nebula generating extended X-ray emission was recently detected surrounding Swift J1834.9–0846. This is the first magnetar for which such a wind nebula was found. Here, we investigate whether there is a plausible scenario where the pulsar wind nebula (PWN) can be sustained without the need of advocating for additional sources of energy other than rotational. We do this by using a detailed radiative and dynamical code that studies the evolution of the nebula and its particle population in time. We find that such a scenario indeed exists: Swift J1834.9–0846's nebula can be explained as being rotationally powered, as all other known PWNe are, if it is currently being compressed by the environment. The latter introduces several effects, the most important of which is the appearance of adiabatic heating, being increasingly dominant over the escape of particles as reverberation goes by. The need of reverberation naturally explains why this is the only magnetar nebula detected and provides estimates for Swift 1834.9–0846's age.
