A HAYEKIAN VIEW ON EUROPEAN UNION

The aim of this paper is to develop some general Hayek’s ideas on the European project. Hayek demonstrated and analyzed the presence of two types of social order - a spontaneous order and a built one. Spontaneous order is a feature of society and economic development around a principle of human action coordinator. European project represents the spontaneous order through the founding principles of the four freedoms - free movement of persons, goods, services and capital. With many regulations, bureaucracy, this order is closer to the order constructed by that social engineering. Following Hayek’s ideas I tried to emphasize some issues at European level and to achieve a correlation with the european reality and Hayekian theory.spontaneous order, rule of law, freedom, institutions

Who Stays and Who Leaves? Findings from a Three-Part Study of Teacher Turnover in NYC Middle Schools

This paper synthesizes findings from the Research Alliance's investigation of teacher turnover in New York City's public middle schools. These years are widely recognized as a critical turning point for students, and the NYC Department of Education (DOE) is pursuing a range of middle school improvement initiatives. The stability of the middle school teaching force has the potential to facilitate or complicate these efforts, yet there have been few studies of the rates and patterns of teacher turnover in the City's middle schools.This study provides the most current, comprehensive look at middle school teacher turnover to date. Drawing on a range of data sources -- including DOE human resource records from the last decade, a survey of over 4,000 full-time middle school teachers, and in-depth case studies in four middle schools -- this paper examines how long middle school teachers remain in their schools, how long they intend to stay, and what predicts whether or not they leave. It also explores how various aspects of teachers' work environment may influence these decisions. Among the key findings: Among middle school teachers who entered their school during the last decade, more than half left that school within three years -- significantly higher than the rates seen for elementary and high school teachers. Of the teachers who leave, most exit the NYC public school system altogether, and only about 1 in 10 transition to another grade 6-8 school. The findings point to several strategies that may be useful for increasing middle school teachers' lengths of stay

Peptide mass fingerprinting using field-programmable gate arrays

The reconfigurable computing paradigm, which exploits the flexibility and versatility of field-programmable gate arrays (FPGAs), has emerged as a powerful solution for speeding up time-critical algorithms. This paper describes a reconfigurable computing solution for processing raw mass spectrometric data generated by MALDI-TOF instruments. The hardware-implemented algorithms for denoising, baseline correction, peak identification, and deisotoping, running on a Xilinx Virtex-2 FPGA at 180 MHz, generate a mass fingerprint that is over 100 times faster than an equivalent algorithm written in C, running on a Dual 3-GHz Xeon server. The results obtained using the FPGA implementation are virtually identical to those generated by a commercial software package MassLynx

Keeping New Teachers: A First Look at the Influences of Induction in the Chicago Public Schools

Examines whether participation in a formal induction program can improve teachers' experiences and job satisfaction, and demonstrates that strong levels of mentoring and support for new teachers greatly improve their desire to continue teaching
