Gestão democrática da educação: a eleição direta para dirigentes de escolas públicas de educação básica do Rio Grande do Norte (2003-2006)

Este trabajo es el resultado de un análisis de la política de gestión de la educación básica en el estado de Rio Grande do Norte (RN) y tuvo como objetivo presentar un estudio sobre la construcción e implementación del proceso de elección directa para elegir a los dirigentes de escuelas públicas de educación básica en las escuelas públicas durante el período 2003 a 2006. Partió de la suposición de que las elecciones para la escoja de los líderes escolares mediante el voto directo de la comunidad se presenta como un importante instrumento a través del cual se debe garantizar el derecho de participación a los diferentes segmentos de la escuela contribuyendo con el proceso de consolidación del proceso democratización de la gestión de escuela pública en ese Estado. Optamos por realizar una búsqueda dentro de un enfoque histórico-crítico, basado, teórico-metodológicamente, en el materialismo dialéctico. A partir de los objetivos y de los temas que guiaron el proceso de investigación, se consideró adecuado adoptar procedimientos de estudio y de recogida de informaciones y análisis bibliográfico y documental y, la realización de entrevistas semi-estructuradas. Los resultados muestran que la construcción del Documento de la Gestión Democrática definiendo la elección directa como una opción de los administradores de la escuela bien como su implantación ante las escuelas del estado sucedió basado en los principios democráticos. Además, los líderes elegidos directamente de las escuelas, la creación del Consejo Escolar (CE) y la institución de la Asamblea General de la Escuela demuestran la adopción de un modelo de gestión de la educación pública del estado que contribuye con el proceso de democratización de la gestión escolar. Por último, es evidente la necesidad de cualificación en el proceso democrático y la participación de varios sujetos involucrados en el proceso de gestión también incluidos los miembros del Consejo Escolar

Nietzsche e a modernidade: da crítica à metafísica à crítica à democracia

This dissertation presents an interpretation concerning the critical considerations of the German philosopher Friedrich Nietzsche on Modernity, especially Nietzsche s criticism of Modernity, of Christian mores and democracy produced by him in Beyond Good and Evil. Nietzsche attentively analyses details of Modernity, produces a diagnosis of modern man and discovers the sign of decay. We consider that Nietzsche s criticism of modernity is directly linked to the criticism of classic metaphysics. We emphasize questions like: what in us aspires to truth? Christian mores: why and what for? What characterizes modernity? Could it be the appeal to the democratic taste? Is it possible to reinvent Modernity? We stress the relation between the notion of truth, democracy and Christian mores, showing that these mores were also inherited from the Socratic culture. We also intend to clarify Nietzsche s proposal of a new way of doing philosophy, that would be able to surpass the decay which rules in European modern culture. The end of this research points out to the ―philosophers of the future‖ who are able, according to Nietzsche, to claim life beyond the metaphysics opposition, beyond the good and the evil

Cargos comissionados da administração pública direta do Rio Grande do Norte: análise comparativa entre o perfil profissional dos cargos comissionados com vínculo funcional e sem vínculo funcional

The professional profile of public administrators in Brazil is changing very rapidly in recent years, seeking to meet the principle of efficiency by public agencies at all levels. The admission of the permanent government employee under the Public Administration is by competition, however, commissioned positions are free appointment of managers, which allows effective participation of external experts according to their respective standards and norms. In this context, this dissertation seeks to understand the main characteristics of the profile of the occupants of commissioned positions in Direct Public Administration of the State of Rio Grande do Norte, noting the differences between those with functional link with the have nots. For this study, by data collection and content analysis, a mapping of the administrative structure of the Government of the State of Rio Grande do Norte was done, i.e., the organization of the Executive Branch, which is regulated by the Complementary Law no. 163/1999 and its amendments, which consists of 53 (fifty three) entities, these 29 (twenty nine) are agencies of the direct administration and the remaining 24 (twenty four) comprises the indirect administration. With the collected data, analysis on the number of commissioned positions of each organ of the State of Rio Grande do Norte and information on education, age, length of service, gender and functional link with the direct administration was carried out. Data were available from SEARH in June/2013, when they totaled 58,733 (fifty-eight thousand seven hundred thirty-three) servers, these 2.15% (two point fifteen percent) occupy commissioned positions, corresponding to 1,262 commissioned positions under the Direct Administration, below the national average of 4% (four percent). Of total commissioned positions 64.7% (sixty-four point seven percent) have no functional link with the direct administration, while only 35.3% (thirty -five point three percent) have functional link. It was noticed that there are no clear and specific criteria for the appointments of commissioned positions in the State. They occur freely, as provided in the State Constitution. Another conclusion is the importance of Public Administration define and improve their capacity, competence and efficiency in the delivery of public services. For that it is necessary to invest in their workforce composed of permanent employees and commissioned positions to define the appropriate professional profile

Trabalhadores por conta própria: O trabalho dos vendedores ambulantes da passarela do Natal shopping e do Via Direta

This study aid to understand the work conditions of street vendors located on the sidewalks of two malls in Brazil Northeast Natal / RN - Both malls Natal Shopping and Via Direta, to analyze their inclusion in the informal economy and to study the supposed autonomy provided by work as self-employment in its both aspects economic and social analyzing the importance on the condition of "masters of their own business" has for the street vendors, as an alternative to not submission to the figure of the boss, that represents the exploitation of one class over another. The theoretical and methodological aspects that support this study was aimed in discussion on the restructuring of production, considering its effects on the world of work, pointing to unemployment as one of the potencies element of excluded processes that exciting workers to engage in the informal market. Informality is presented as a survival strategy and as integrating part of the reproduction of capital. This research was conducted under a critical perspective, whish has been utilized quantitative and qualitative analyses. The results of this study format questions that provided during the research process the socio-economic characterization of workers, main cause of this study, and how street vendors expres their status of workers as self-employed for their work, and the perception that they have on their form of inclusion in the informal market.

Extensões ao Projeto LVWNet: mobilidade, interação com equipamentos reais, comunicação direta, e registro dinâmico de nós

Due to the constantly increasing use of wireless networks in domestic, business and industrial environments, new challenges have emerged. The prototyping of new protocols in these environments is typically restricted to simulation environments, where there is the need of double implementation, one in the simulation environment where an initial proof of concept is performed and the other one in a real environment. Also, if real environments are used, it is not trivial to create a testbed for high density wireless networks given the need to use various real equipment as well as attenuators and power reducers to try to reduce the physical space required to create these laboratories. In this context, LVWNet (Linux Virtual Wireless Network) project was originally designed to create completely virtual testbeds for IEEE 802.11 networks on the Linux operating system. This paper aims to extend the current project LVWNet, adding to it the features like the ability to interact with real wireless hardware, provides a initial mobility ability using the positioning of the nodes in a space coordinates environment based on meters, with loss calculations due to attenuation in free space, enables some scalability increase by creating an own protocol that allows the communication between nodes without an intermediate host and dynamic registration of nodes, allowing new nodes to be inserted into in already in operation network

Aplicação da modelagem estrutural computacional direta na análise da geometria de falhas: exemplo da falha de Baixa Grande (Bacia Potiguar - NE do Brasil)

The Baixa grande fault is located on the edge of the S-SW Potiguar Rift. It limits the south part of Umbuzeiro Graben and the Apodi Graben. Although a number of studies have associated the complex deformation styles in the hanging wall of the Baixa Grande Fault with geometry and displacement variations, none have applied the modern computational techniques such as geometrical and kinematic validations to address this problem. This work proposes a geometric analysis of the Baixa Fault using seismic interpretation. The interpretation was made on 3D seismic data of the Baixa Grande fault using the software OpendTect (dGB Earth Sciences). It was also used direct structural modeling, such as Analog Direct Modeling know as Folding Vectors and, 2D and 3D Direct Computational Modeling. The Folding Vectors Modeling presented great similarity with the conventional structural seismic interpretations of the Baixa Grande Fault, thus, the conventional interpretation was validated geometrically. The 2D direct computational modeling was made on some sections of the 3D data of the Baixa Grande Fault on software Move (Midland Valley Ltd) using the horizon modeling tool. The modeling confirms the influence of fault geometry on the hanging wall. The Baixa Grande Fault ramp-flat-ramp geometry generates synform on the concave segments of the fault and antiform in the convex segments. On the fault region that does not have segments angle change, the beds are dislocated without deformation, and on the listric faults occur rollover. On the direct 3D computational modeling, structural attributes were obtained as horizons on the hanging wall of the main fault, after the simulation of several levels of deformation along the fault. The occurrence of structures that indicates shortening in this modeling, also indicates that the antiforms on the Baixa Grande Fault were influenced by fault geometry
