The parliamentary representation in the Southern Cone integration is the main issue in this article, which analyzes some implications of the institutionalization of Mercosur Parliament (Parlasur). Consolidation and deepening of the integration process are related to the very weakness of congressional action under the Joint Parliamentary Committee and even the Parlasur. The hypothesis is that the creation of the Mercosur Parliament could contribute to the integration process only insofar as it could overcome the limitations experienced by the Joint Parliamentary Commission and go forward in building a democratic and representative body of regional integration.

This paper analyzes patterns of political mobility of a specific social stratum - immigrants and their descendants - in the western region of São Paulo, where coffee economy prevailed since the last quarter of the XIXth century. We investigate the main agents of local politics in seven cities: from the traditional oligarchic regime characteristic of the Old Republic to the processes of political transformation in the thirties that resulted in the post-war re-democratization, when a recomposition of local political elites takes place.

The ever more interconnected and competitive markets have contributed to the increase in the number of companies seeking mergers and acquisitions, as they undergo significant cultural dimensions that can influence the success of an organization. This study analyses how the process of change can happen, considering the importance of culture, the complexities of the internal public and the interaction between professionals, with the aid of Public Relations. The analysis is grounded on theoretical principles concerning intercultural communication and the role of the professional as a manager of communicational barriers. It also recommends the application of storytelling as an organizational strategy in order to mediate potentially conflicting changes that could be facilitated with the work of Public Relations

Os seres humanos identificam naturalmente outros seres humanos utilizando suas características físicas, fisiológicas ou comportamentais. Dentre essas características, destacam-se os traços faciais. O avanço tecnológico na área de Biometria tem promovido o desenvolvimento de inúmeras técnicas para o reconhecimento automático de faces por meio de computadores, entretanto, existem ainda vários fatores que dificultam esta aplicação, como por exemplo, a variação das condições de iluminação. O objetivo deste artigo é analisar os efeitos da aplicação de um filtro de processamento de imagens, denominado Transformada Census, em uma base de dados com imagens da face em diferentes condições de iluminação. Assim, experimentos foram realizados utilizando a técnica PCA com imagens da base de dados AR antes e depois da aplicação da Transformada Census. Os resultados desses experimentos mostraram que a aplicação da Transformada Census melhorou o resultado do reconhecimento das faces, reduzindo a taxa de erro.

The teaching/learning activities of the daylighting built environment require from the Architecture and Urbanism undergraduate student the ability to abstract the effects of daylight distributed in three-dimensional space that is being designed. Several tools and techniques can be used to facilitate the understanding of the involved phenomena, among which the computational simulation. This paper reports the digital inclusion of the daylighting teaching in the Architecture and Urbanism undergraduate course at the School of Architecture, Arts and Social Communication of Bauru (FAAC) of UNESP – Sao Paulo State University, that began in 2010. The inclusion process involved free software use, specifically the programs DIALux and SketchUp+Radiance, both with graphical output for the illuminated scenes visualization and for result analysis. The graphic model is converted from SketchUp to Radiance by a plugin and a user-friendly interface for Windows was developed to simulate the lighting. The process of digital inclusion is consolidated, with wide acceptance by students, for which computational simulation facilitates understanding of relation between daylight and built environment and helps the design process of elements for daylighting control.

To understand how teachers deal with curriculum change proposals, and how their professional knowledge are involved in this process, is critical in order to understand the impact of these changes in pedagogical practice. From L. S. Shulman’s typology of teacher knowledge, we aimed to describe and interpret how a Physical Education teacher deals with the pedagogical content knowledge when developing a theme from Curriculum Proposal of Physical Education from the State of São Paulo (PPC-EF). A case study was conducted with the use of semi-structured interviews and classroom observation. The teacher made adjustments at the approach and activities suggested by the PPC-PE, mobilizing several teacher knowledge, and her autonomy was not removed. On the other hand, difficulties in relating “theory” and “practice” indicate the need for construction of pedagogical content knowledge to better direct the learning of students to the critical appropriation of movement culture.

In this paper, we will present an overview of the smart grid defining the three main systems that compose it: smart infrastructure system, smart management system and smart protection system. We will conceptualize a functionality of smart management system, the conservative voltage reduction, citing its benefits and its history of application. And, finally, we'll cover a test in which we reduce the nominal voltages on incandescent bulbs, CFL and LED, in the context of residential lighting, and on LED and HPS, in the context of public lighting. The test aims to check whether the voltage reduction adversely affects sources of lighting by measuring the temperature manually with a thermal imaging camera FLIR and illuminance with a LUX meter. The set of power factor, total harmonic distortion, and input power values will be collected automatically through the power quality Analyzer Fluke 345 with a probe Fluke Hall Effect Current. For residential lighting, it was found that both CFL and LED had good performance with the smallest variations in illuminance. Between both, the LED source had the lowest harmonics and the lowest power consumption, on the other hand incandescent bulbs had a bad performance as expected. Public light sources also had a good performance and obtained power factors within the standards, as opposed to the CFL and LED residential sources. The data collected clearly shows the feasibility for nominal voltage reductions. Even with small reductions, there are possibilities of savings which can be passed on to the utilities and consumers

This work presents a self-sustainable lighting system using ultracapacitor as a storage device, replacing the conventional battery, using solar energy as the only energy supplier. A detailed study of solar panels, switched mode converters and ultracapacitors was made, in order to design a circuit capable of capturing solar energy and transfer it efficiently to a bank of ultracapacitors. Later, at nighttime, this energy is used for lighting in LED luminaires which have high luminous efficiency and high reliability index. This work presents the design of the solar panel, ultracapacitors bank, the development of the voltage converter circuit and charger working at the maximum power point of the solar panel. All subsystems were simulated and it was shown that the use of ultracapacitors is feasible to feed a LED lamp with enough brightness for a person to walk at night, for two night shifts, using a capacitive bank with twenty-four ultracapacitors. Replacing the battery by an ultracapacitor allows a faster recharge, with low maintenance costs, since ultracapacitors have a lifetime bigger than batteries; beyond reducing the environmental impact, as they don't use potentially toxic chemical compounds

Structural changes and labor market in Brazil. In the present article, we attempt to identify the sources of the changes in the labor schooling level in the three main sectors of the Brazilian economy: manufacturing, services and agriculture. It was verified that, despite the changes in the product and employment among sectors, mainly in the 1990s, the relative demands for qualified workers has not experimented significant changes. Moreover, in the periods in which schooling has increased more, the workers' wage has decreased more. This fact suggests that the increase in labor qualification was mainly due to the increase of this factor supply. The structural changes had contributed, in general, in a marginal and negative way to labor force level of qualification demand in all the three sectors.

O ensaio procura apontar as linhas de força que compõem o caráter dramático do narrador em Angústia. Estuda, para tanto, o movimento circular da escrita, cuja forma embaralha tempos e espaços de modo a sugerir o desconcerto. Como resultado parcial, centra-se, em termos de análise, nos primeiros fragmentos do romance a fim de compreender o refluxo das imagens que perfazem o enredo.
