Private tutoring through the internet: globalization and offshoring
Alexandre Ventura,장선화 서울대학교 교육연구소 2010 Asia Pacific Education Review Vol.11 No.1
The private tutoring industry has come forward as the third great sector of education. The common sense representation about private tutoring is changing. The growing search for supplementary educational support services and the technological innovation have created a new paradigm. This paper focuses on one of the most interesting faces of this new phenomenon: the rise of private tutoring through the internet. The very promising market is considered by some analysts as a true explosion on the offer and demand levels. Many families are feeling increasingly unable to provide their children the `` extra help'' they need to meet the requirements of further steps in the education system. So, for several reasons, they are outsourcing and even offshoring this so important and competitive task. The field is full of learning and market opportunities. This is the new globalized world of the less shadow and progressively growing private tutoring in the XXI century.

Plant growth-promoting rhizobacteria (PGPR) are considered to have a beneficial effect on host plants. Azospirillum brasilense is a diazotroph associated with important agricultural crops such as maize and wheat, and has been used as model organism to investigate associative plant growth promotion. In this study, we have employed scanning electronic microscopic to observe the presence of bacterium on the root surface. Two-dimensional gel electrophoresis and mass spectrometry were used to analyze the changes in protein profile of maize roots in response to A. brasilense strain FP2 7 days after inoculation and we observed 46 differently expressed protein spots. We report the identification of three of these proteins.
