Natal qual é a sua cara?: análise do perfil edilício da avenida Eng. Roberto Freire (Natal/RN) à luz da acessibilidade

This study focuses on the building ensemble of Avenida Roberto Freire, a main road in Natal, Brazil, as a material expression of the confluence of various factors among which the following may be emphasized: high level of accessibility due to urban spatial re-structuring and the growth of the real estate market, in view of the increasing number of consumers, who arrived in Natal within the last decades. The intense urban modification process that has been going on in Natal since at least the 1980s, has engendered the formation of long axial lines which express the expansion dynamics and some of the forces subjacent to it. Avenida Roberto Freire has been an iconic example of an urban thoroughfare where architecture becomes primarily a communication support that can be perceived by fast moving passers-by, what brings it close to the venturian concept of strip (Venturi at al, 1972). The building types that line the road not only respond to the dynamics in process but also contribute to intensify it, as they house a variety of uses which attract people and generate more movement. The dynamics is further strengthened by the action of the real estate business which benefits from the increase of highly accessible locations, and from the private and public investments and incentives to tourism that aim to insert this city into the globalized world. Although the intention of reconstituting part of the history of density increase on this avenue in a diachronical perspective was attempted within the limits of the available references and documentation, the central contribution of this study is to understand the relations between topological accessibility and the typological nature of the building ensemble. By observing the synchronic morphological frame resulting from the spatial configuration analysis pertinent to this avenue (cf. Hillier and Hanson,1984) and the inventory and classification of the building ensemble there existing, this study aims to understand how architecture responds to accessibility in view of the real estate pressure, boosted by a cosmopolitanizing process brought about by the continuous flow of foreign and Brazilian arrivals as visitors, temporary or permanent residents

Coleman’s third report

The article analyses the (third) Coleman Report on private and public schools. The report scrutinises the relationship between private and public schools and shows that private school students show better academic achievement. Coleman concluded that these findings provided a strong argument in favour of public financial support for private schools. However, he identified a number of school characteristics that he believed to be related to student achievement. According to his analysis, these characteristics were not limited to private schools; public schools exhibiting the same characteristics also had good results. Coleman interpreted the available data in favour of financial aid to private schools, although this was not the only possible interpretation. An alternative conclusion would have been to encourage these characteristics in public schools. Why did Coleman disregard this possibility? Why did he deviate from his usual scientific rigour? The present article suggests that there appear to be two reasons for the narrow interpretation of the relationship between public and private schools in Coleman's third report. The first lies in Coleman's notion of contemporary society as a constructed system in which every individual actor holds a place in the structure and requires incentives in order to act to the benefit of society. In the case of education, the goal of the institution is to ensure the high cognitive achievement of students, and the incentive is related to choice and competition. The second reason is related to Coleman's vision of sociology as a discipline aiding the construction of an effective society. (DIPF/Orig.)

A violência no contexto escolar : percepção de professores e estudantes da rede de ensino pública e particular na cidade de Maceió

Enquadramento teórico: A realização deste trabalho surgiu da própria vivência profissional enquanto professor de Educação Física, lidando com alunos sem perspectivas de futuro, desmotivados, de comportamento agressivo, e com alto grau de indisciplina, caracterizando um perfil violento. A escola atualmente aparece como palco de tensões e a preocupação é evidente já que a escola deve ser um local onde as relações do dia-a-dia traduzem respeito, harmonia, socialização e aquisição de normas e valores, onde os alunos constroem a sua personalidade e uma identidade. Objetivos: Analisar os tipos e frequência da violência no contexto escolar de escolas da rede pública e particular de ensino na cidade de Maceió; Analizar os factores geradores da violência e projetos minimizadores da mesma. Metodologia: Estudo descritivo, exploratório de natureza quantitativa, com 200 professores e 800 alunos de 6 escolas da Rede Pública e Particular de Ensino de Maceió-AL. Resultados: Predomínio de estudantes do sexo feminino, sendo 71,2% na escola pública e 58,% na escola particular, na faixa etária entre os 15-18 anos (65.5%) . Os professores foram de 65% do sexo feminino e 35% do sexo masculino na rede Publica e 45% e 55% na rede Particular, com idades entre os 20 e 60 anos, tendo sido 78% admitidos através de concurso público, com estabilidade vínculo efetivo nesta rede de ensino. Todos os professores da Rede Particular de Ensino atuam sob o regime de contrato com carteira assinada, seguindo a CLT (Consolidação das Leis do Trabalho). Forte predominância da violência verbal em ambos os tipos de instituições e em ambos os sexos e que se somadas perfazem um total superior a 75%. O sumatório de estudantes que em algum momento sofreu violência, nas duas escolas é de 11.4%. De realçar que 39,2% e 28% dos estudantes da escola pública e particular respectivamente informarem que ninguém o ajudou nestas situações. Na escola Publica os fatores mais relatados como geradores de violência foram: Uso de drogas com 14%, as famílias desestruturadas com 14% e a falta de educação doméstica com 13%. Na rede particular 45 % dos professores referem a desestruturação familiar e 35% a práticas de Bullying. Quando questionados sobre o sentimento de segurança na rede publica apenas 8% se sente seguro. Na rede particular, 65% afirmaram sentir-se seguros. Conclusões: A violência ocorre em ambas as escolas da rede pública ou particular, com menor proporção nas escolas da rede particular, tendo em vista que os projetos desenvolvidos, a estrutura física, e recursos humanos, estão presentes a contento. Ambos os públicos estudantis, convivem e se relacionam nesse mesmo cenário social extraescolar, e que carece ser ocupado em termos de políticas públicas que agreguem valor na formação desse jovem.

Impactos da adoção de sistemas de informação no judiciário: pesquisa com usuários do sistema processual virtual em um juizado especial federal

The Information Technology (IT) is increasing his applicability to business, both private and public companies. It is necessary the adequate use of the new technologies and get cooperation and technology acceptance of the system. People tend to resist to the changes, contributing so that the technology is rejected or even it is not recognized as promoting of the changes. This study is relevant and aim to evaluate the impacts of new technologies, considering their users as fundamental factors in the change process. The survey analyzed the advantages and the barriers of the system use in three federal special judicial of Rio Grande do Norte, with data collected in May of 2007, through the application of questionnaires to thirty eight users of the virtual system CRETA. The users' perception was evaluated, under the optics of five variables: efficiency, image, agility, ease of use and quality. Starting from the obtained results, it was evidenced that the implementation of the system felt accordingly the expected and it reached the objectives intended that were: the velocity and efficiency in the path of the lawsuits, larger productivity, resulting in a better quality of the final work introduced to the citizen and proportionate an improvement in the organizational image of the judiciary power

Optimal sequence of landfills in solid waste management

Given that landfills are depletable and replaceable resources, the right approach, when dealing with landfill management, is that of designing an optimal sequence of landfills rather than designing every single landfill separately. In this paper we use Optimal Control models, with mixed elements of both continuous and discrete time problems, to determine an optimal sequence of landfills, as regarding their capacity and lifetime. The resulting optimization problems involve splitting a time horizon of planning into several subintervals, the length of which has to be decided. In each of the subintervals some costs, the amount of which depends on the value of the decision variables, have to be borne. The obtained results may be applied to other economic problems such as private and public investments, consumption decisions on durable goods, etc.

Os forrós da Serra da Gameleira (São Tomé/RN) : etnicidade, festa e sociabilidade

This work intends to describe and analyze the parties of forró that happen in Serra da Gameleira, in São Tomé/RN. Serra is a divided social space: groups of different ethnic origins live together in Gameleira de Baixo, Salgadinho (or Gameleira de Cima) and Chaves Belas. They are approximately two hundred families that live exclusively from agriculture. We try to understand how the parties inform about the social organization, the ethnic composition of the families that live there and the past of Serra, through the genealogy offorró players. In the discussion, we identify the festive places: in the total, we have Five houses of forró that function regularly one of them has been described. The private and public spaces inside them are intimate related, with no clear limits between the house of forró and the residence. Each house of forró has an owner, that regularly makes the parties, mobilizing a big part of the inhabitants, and provoking the straitening of the social relations. Observing the festive sociability between different social segments, the forró appears like na element that minimizes social conflicts, providing news ways of association and cooperation in the space of Serra da Gameleira. For the collection of facts, we used the ethnographic method, through the direct observation, interviewing and documentary research. The local history is recounted following the routes of oral memory and historical documents analysis. In the end of the analysis, we concluded that music and party are elements that aggregate the different groups that live in the location and determine forms of expression of what is seen as a traditional culture

Standardized environmental management systems as an internal management tool

In a principal-agent model we analyze the firm’s decision to adopt an informal or a standardized Environmental Management System (EMS). Our results are consistent with empirical evidence in several respects. A standardized EMS increases the internal control at the cost of introducing some degree of rigidity that entails an endogenous setup cost. Standardized systems are more prone to be adopted by big and well established firms and under tougher environmental policies. Firms with standardized EMS tend to devote more effort to abatement although this effort results in lower pollution only if public incentives are strong enough, suggesting a complementarity relationship between standardized EMS and public policies. Emission charges have both a marginal effect on abatement and a qualitative effect on the adoption decision that may induce a conflict between private and public interests. As a result of the combination of these two effects it can be optimal for the government to distort the tax in a specific way in order to push the firm to choose the socially optimal EMS. The introduction of standardized systems can result in win-win situations where firms, society and the environment get better off.

O terciário (re) desenhando a periferia: a região administrativa norte de Natal/RN, na última década do século XX, servicializada na Av. Dr. João Medeiros Filho

The tertiary sector has been (re)defining and (re)qualifying, in an impacting way, the urban spaces in the cities, introducing new elements for the discussion of the relationship center/periphery. In Natal, as an inducing economic activity of its development, it conforms to the new needs of the capital, expanding, being materialized through several processes and spatial forms. We aim at analyzing one of those processes, which has taken its Northern Administrative Area to (re)define the design of its urban space, through the actions developed by the agents involved with the spatialization of the tertiary activities, at the same time as it redimensions its role as a periphery of Natal, contributing to the study of the recent and growing transformations of the Brazilian capitals. The studied district corresponds to 39.4% of the municipal area and, until recently, was composed by precarious reproduction spaces, unprovided of relevant economical activities. After the boom of the development of extensive housing complexes by SFH/BNH, the area, gradually stopped being a dependent area, and it imposed itself as an economically participant region, with the increase of the trade and services sectors, as well as a favorable place for the appearance of new activities. Its reflexes are noticeable in the achieved spatial configuration. As the main road to induct changes, Dr. João Medeiros Filho Avenue presents these new tendencies in the production of the intraurban space, concentrating the largest goods and services equipments of the area, through investments of the private and public sectors, which guarantee the capital allocation for the construction of a new centrality

Derechos colectivos de las y los servidores públicos al amparo de las Enmiendas Constitucionales de 2015

La Constitución de la República del Ecuador vigente desde el año 2008, reconoce y garantiza derechos para los ciudadanos domiciliados en el país, entre ellos trabajadores/as y servidoras y servidores públicos. En diciembre de 2015, la Asamblea Nacional del Ecuador, mediante el procedimiento de Enmienda Constitucional unificó el régimen laboral de las personas que prestan sus servicios laborales en las instituciones y organismos estatales, debiendo adecuarse la normativa legal y secundaria a esta modificación de la Carta Magna hasta junio de 2016. En el presente trabajo abordaremos en su primer capítulo antecedentes históricos del derecho al trabajo en general y la legislación histórica que ha regido en nuestro país. En el segundo capítulo nos centraremos en distinguir cuales son las características del régimen laboral público y del privado en Ecuador y realizaremos recomendaciones en relación a derechos individuales de los servidores públicos. En el tercer capítulo haremos referencia a los Convenios Internacionales de la OIT ratificados y no ratificados por nuestro país. En el cuarto capítulo estableceremos similitudes y diferencias entre las legislaciones regionales en razón del reconocimiento de derechos colectivos para servidores públicos. En el capítulo cinco detallaremos criterios doctrinarios sobre los derechos de ejercicio colectivo, es decir: huelga, convenio colectivo y sindicalización en el sector público para finalmente en el sexto y último capítulo dar recomendaciones para la inminente reforma a la Ley Orgánica de Servicio Público, LOSEP.

Fenómeno del Niño historia y perspectivas

Ecuador se ubica en zona de riesgo para la llegada del Fenómeno del Niño, por lo que es necesario estar informados sobre este tema y diferenciar que es la Corriente del Niño (corriente cálida del Pacífico Sudamericano) y el Niño-Oscilación del Sur (patrón climático en el que se producen oscilaciones de la temperatura en dos fases: el Fenómeno del Niño y La Niña). En los años 1997-1998 este fenómeno afectó el 60% del total de la población, con un impacto muy alto en la salud de la ciudadanía, así como en la propiedad pública privada y en diversos ecosistemas. Ante la amenaza en el periodo 2015-2016, la Secretaría de Gestión de Riesgos (SGR) planificó tres etapas de acción: Preparación, Respuesta y Rehabilitación. Luego de la revisión los autores recomiendan entre otras cosas: brindar información oportuna sobre los cambios meteorológicos, informar sobre los planes de contingencia, garantizar la seguridad alimentaria y el acceso al agua; y fortalecer la atención integral que proveen los Servicios de Salud

Testimonios de un Pasado Imperfecto : Vida Cotidiana de Mujeres bajo Dictadura en Valparaíso y Viña del Mar, Chile 1980-1987

Este proyecto de investigación se caracteriza como estudio histórico-etnográfica basado en estudios de casos de la vida cotidiana de nueve mujeres en Valparaíso y Viña del Mar durante la dictadura chilena, analizando el testimonio de los efectos del régimen autoritario en la vida cotidiana de estas mujeres chilenas entre 1980 y 1987. La metodología se radica firmemente en el método etnográfico con entrevistas semi-abiertas y el análisis del discurso de los relatos. En la metáfora de la arpillera (un tapiz anónimo cosido en lona ensamblado a partir de piezas de tela que muestra escenas de la vida cotidiana o protesta la dictadura de Pinochet), trozos y pedazos de experiencia se juntan en el encima de la lona de la historia para dar forma al testimonio de vida la vida cotidiana. Este proyecto se centra en tres aspectos diferentes de la relación entre el Estado autoritario y la vida cotidiana: las técnicas de gobernabilidad (macro), narraciones de silencio y miedo (micro) y trayectorias narrados (espacial), el último inspirado por el ensayo Halbwachs en caminar por la ciudad. Para cerrar, la relevancia del estudio se destaca por el intento de comprender el efecto de un estado autoritario en el sujeto femenino y las respuestas y adaptaciones que las mujeres chilenas adoptaron en la vida privada y pública mediada por la violencia y el miedo bajo dictadura. La dialéctica del acontecimiento y la rutina de la vida cotidiana bajo la dictadura se unen en las memorias narradas, mediada por el presente vivido, lo cual permite una reflexión sobre la cuestión de la alteridad en la sociedad chilena.Este proyecto de investigación se caracteriza como estudio histórico-etnográfica basado en estudios de casos de la vida cotidiana de nueve mujeres en Valparaíso y Viña del Mar durante la dictadura chilena, analizando el testimonio de los efectos del régimen autoritario en la vida cotidiana de estas mujeres chilenas entre 1980 y 1987.

Towards near-threshold server processors

The popularity of cloud computing has led to a dramatic increase in the number of data centers in the world. The ever-increasing computational demands along with the slowdown in technology scaling has ushered an era of power-limited servers. Techniques such as near-threshold computing (NTC) can be used to improve energy efficiency in the post-Dennard scaling era. This paper describes an architecture based on the FD-SOI process technology for near-threshold operation in servers. Our work explores the trade-offs in energy and performance when running a wide range of applications found in private and public clouds, ranging from traditional scale-out applications, such as web search or media streaming, to virtualized banking applications. Our study demonstrates the benefits of near-threshold operation and proposes several directions to synergistically increase the energy proportionality of a near-threshold server.
