Práticas clientelistas e dádivas como estratégias de hegemonia política: uma análise sobre o campo da saúde em Mossoró-RN

The reality experienced by many families and individuals who seek and require the services of the Unified Health System - SUS, the relationships between users, health professionals, and political representatives, establishes the core of the issue that guides the choice and interest of this study concerning the prominence of clientelist practices and gifts that permeate the health field. The research is based on the analysis and reflection of the intrinsic relationship between the health and political fields. It analyses the health field and its relationship with the dynamics and developments of the local political scenario relating it to the implementation of the Family Health Program and Community Health Agents Program (PACS/PSF health programs) in the city of Mossoró, State of Rio Grande do Norte which refers to the period 1991-2010; and falls into a methodological perspective of qualitative approach. The methodological tools and techniques used were based on semi-structured interviews, direct observation of the field, journalistic texts and documentary sources. The construction and questioning of the object of the research were based on theoretical contributions from authors discussing the social field and symbolic power: Bourdieu (2005); clientelist relationships and gifts from asymmetric exchanges: Rouland (1997), Lanna (1995), Martins (1999), Carvalho (1999), Diniz (1982); exercise of hegemony and political strategy from authors who analyse this subject: Gramsci (1995), Coutinho (1981), and Gruppi (1978). Furthermore, the research has established dialogues with authors who address the dynamics of Brazilian politics such as Baquero (2001) and Weffort (1993). The collected data were subjected to qualitative content analysis. The results showed that with the implementation of the PACS/PSF programs in the aforementioned city, the health field has established itself as a key scenario for the exercise of political hegemony of the factions that dominate this socio-political context, resizing clientelist practices, however, without modifying the power structures within this social scenario

Proteção em sistemas elétricos com geração distribuída utilizando a transformada wavelet

A typical electrical power system is characterized by centr alization of power gene- ration. However, with the restructuring of the electric sys tem, this topology is changing with the insertion of generators in parallel with the distri bution system (distributed gene- ration) that provides several benefits to be located near to e nergy consumers. Therefore, the integration of distributed generators, especially fro m renewable sources in the Brazi- lian system has been common every year. However, this new sys tem topology may result in new challenges in the field of the power system control, ope ration, and protection. One of the main problems related to the distributed generati on is the islanding formation, witch can result in safety risk to the people and to the power g rid. Among the several islanding protection techniques, passive techniques have low implementation cost and simplicity, requiring only voltage and current measuremen ts to detect system problems. This paper proposes a protection system based on the wavelet transform with overcur- rent and under/overvoltage functions as well as infomation of fault-induced transients in order to provide a fast detection and identification of fault s in the system. The propo- sed protection scheme was evaluated through simulation and experimental studies, with performance similar to the overcurrent and under/overvolt age conventional methods, but with the additional detection of the exact moment of the fault.
