Definição e abordagem de currículo: exame de um curso de formação de professores para a educação não formal em ONGs

This article presents a research aimed to analyze the approach and the definition of guiding curriculum of teacher training for work in the non-formal education in non-governmental organizations (NGOs). We opted for a qualitative approach and case study of Te- acher Training Course for NGOs, developed by Ong São Paulo-SP. The research instruments were: analysis of documents of the cou- rse, interviews with trainers and coordinator and literature review. In this course, curriculum is defined as a path to be followed by students and instructors and the coordinator of the subjects studied. We adopted the so-called Integrated Curriculum, in which teaching occurs by the study of problem situations and integrators of learning projects. At the end, we suggest improving the course and following that information, it is hoped, one will support the production of fur- ther comparative research.

A importância da gestão da comunicação e da informação nas empresas socialmente responsáveis

This paper studies the communication and information management in the perspective of corporate social responsibility. We assume that a company becomes socially responsible when it’s necessary implementing a communication and information policy able to align their business management processes to social responsibility policies, thus creating the necessary, fundamental synergy to their audiences. We raised the hypothesis that corporate social responsibility, in order to be incorporated on a business process management, necessarily involves a transformation in the form of information management and communication - understood as strategic skills which enable the generation of knowledge creation value and the acquisition of awareness of ethical conduct and company's corporate organizational culture as a mirror, reflected to its internal and external audiences. Therefore, this study was supported by a case study in a retail company in Bauru city, regarded as a socially responsible company. Thus, we proceeded to develop a descriptive-exploratory field research, by using the technique of structured interviews which were conducted with the most representative considered leaders of the company - management, store managers, responsible CSR department and advertising agency

Comunicação organizacional, informação e responsabilidade social: uma nova relação

Study on the Organizational Communication and the information from the perspective of the corporate social responsibility (CSR). Presumes that the CSR to be incorporated into a process of business management involves a transformation in the ways of communication and information management. The objective is to think about the essential function of the communication and information as strategic competences of socially responsible companies, in the knowledge generation, in the value creation and in the incorporation of awareness of ethical conduct and company’s corporate, as reflector of its organizational culture, reflected to its stakeholders.

PM(10) remote sensing from geostationary SEVIRI and polar-orbiting MODIS sensors over the complex terrain of the European Alpine region

The subject of this study is to investigate the capability of spaceborne remote sensing data to predict ground concentrations of PM10 over the European Alpine region using satellite derived Aerosol Optical Depth (AOD) from the geostationary Spinning Enhanced Visible and InfraRed Imager (SEVIRI) and the polar-orbiting MODerate resolution Imaging Spectroradiometer (MODIS). The spatial and temporal resolutions of these aerosol products (10 km and 2 measurements per day for MODIS, ∼ 25 km and observation intervals of 15 min for SEVIRI) permit an evaluation of PM estimation from space at different spatial and temporal scales. Different empirical linear relationships between coincident AOD and PM10 observations are evaluated at 13 ground-based PM measurement sites, with the assumption that aerosols are vertically homogeneously distributed below the planetary Boundary Layer Height (BLH). The BLH and Relative Humidity (RH) variability are assessed, as well as their impact on the parameterization. The BLH has a strong influence on the correlation of daily and hourly time series, whilst RH effects are less clear and smaller in magnitude. Despite its lower spatial resolution and AOD accuracy, SEVIRI shows higher correlations than MODIS (rSEV∼ 0.7, rMOD∼ 0.6) with regard to daily averaged PM10. Advantages from MODIS arise only at hourly time scales in mountainous locations but lower correlations were found for both sensors at this time scale (r∼ 0.45). Moreover, the fraction of days in 2008 with at least one satellite observation was 27% for SEVIRI and 17% for MODIS. These results suggest that the frequency of observations plays an important role in PM monitoring, while higher spatial resolution does not generally improve the PM estimation. Ground-based Sun Photometer (SP) measurements are used to validate the satellite-based AOD in the study region and to discuss the impact of aerosols' micro-physical properties in the empirical models. A lower error limit of 30 to 60% in the PM10 assessment from space is estimated in the study area as a result of AOD uncertainties, variability of aerosols properties and the heterogeneity of ground measurement sites. It is concluded that SEVIRI has a similar capacity to map PM as sensors on board polar-orbiting platforms, with the advantage of a higher number of observations. However, the accuracy represents a serious limitation to the applicability of satellites for ground PM mapping, especially in mountainous areas.

A randomized trial for the treatment of refractory status epilepticus

Refractory status epilepticus (RSE) has a mortality of 16-39%; coma induction is advocated for its management, but no comparative study has been performed. We aimed to assess the effectiveness (RSE control, adverse events) of the first course of propofol versus barbiturates in the treatment of RSE.
