Developing Integral Ecologists: Description and Analysis of the State of Environmental Education at Jesuit High Schools in Light of Religious Ecological Commitments and Science Education Research

This research responds to numerous calls to focus more immediately and deeply on environmental education in the context of local communities. Jesuit high schools offer a rich network to study this movement, as schools with long histories of scholarly and moral concerns for forming students to think about and act on worldwide problems. The key research question is: How can science education research inform environmental education in these schools? The research methodology includes data collection and analysis of publicly-accessible website data, phone interviews with teachers, and a literature review of science education research. Recommendations are given for vertically aligning the diverse environmental education activities at these schools with coherent standards for student development of specific environmental competencies

Mediacenter Model

Digitalization and convergence are two determining accompaniment in the market of multimedia enterprises. Shortly, one and only set will contain all functions of personal computers, televison sets, and mobile and line telephones as well, but despite of this multifunctionality, people can hold this new set in a pocket. This will change the structure of manufacturers, the activity of motion picture makers, and the behavior of consumers as well. The enterprises, using analog technology, will drop behind new entrants to market starting with digital, and surely lost the competition against those, which was able to develop, or change to digital technology. Digital broadcasting offers better image quality, and more economical transfer. The habits of watching television programme will also be converted into a more free way, according to the possibilities of Internet video share portals, but not neccessarily free of charge. The financial ways in Hungary, will also change just as in more developped countrys in Europe, and in the World.

Implementation of a Two-Channel Maximally Decimated Filter Bank using Switched Capacitor Circuits

The aim of this paper is to describe the implementation of a two-channel filter bank (FB) using the switched capacitor (SC) technique considering real properties of operational amplifiers (OpAmps). The design procedure is presented and key recommendations for the implementation are given. The implementation procedure describes the design of two-channel filter bank using an IIR Cauer filter, conversion of IIR into the SC filters and the final implementation of the SC filters. The whole design and an SC circuit implementation is performed by a PraCAn package in Maple. To verify the whole filter bank, resulting real property circuit structures are completely simulated by WinSpice and ELDO simulators. The results confirm that perfect reconstruction conditions can be almost accepted for the filter bank implemented by the SC circuits. The phase response of the SC filter bank is not strictly linear due to the IIR filters. However, the final ripple of a magnitude frequency response in the passband is almost constant, app. 0.5 dB for a real circuit analysis
