Problems of Navajo Male Graduates of Intermountain School During Their First Year of Employment

One of the primary objectives of education in the United States is to prepare young people for adult life. They are expected to become a part of the social and civic life of the community, and by working in a vocation to contribute to their own personal welfare and that of the society in which they live

Foreign National Doctoral Students In U.S. Economics Programs

This paper examines why enrollment of foreign national students in U.S. economics graduate programs increased so dramatically since the 1960s.   New information regarding the “stay rates” of foreign national students is examined.  The paper concludes that growth in the number of  foreign national economics graduate students was related to the quality of U.S. graduate programs, growth in foreign social science baccalaureate degree awards, growing foreign incomes, and movement of foreign economies towards markets.  These trends were especially pronounced in Asia, where most foreign national economics students are from

Fringe calibration using neural network signal mapping for structured light profilometers

We present a novel neural network signal calibration technique to improve the performance of triangulation based structured light profilometers. The performance of such profilometers is often hindered by the capture of noisy and aberrated pattern intensity distributions. We address this problem by employing neural networks and a spatial digital filter in a signal mapping approach. The performance of the calibration technique is gauged through both simulation and experimentation, with simulation results indicating that accuracy can be improved by more than 80%

Earnings And Job Satisfaction Of US Science And Engineering Baccalaureate Recipients With Advanced Degrees

Using 2003 US data, this paper examines job satisfaction and economic returns to science and engineering (STEM) baccalaureate recipients who obtain STEM PhDs or professional degrees in the fields of law, MBA, medicine, and MS engineering. The salient finding of this research is that the future STEM PhD supply will largely be determined by the availability of tenured academic positions. Despite inferior economic returns, job satisfaction for STEM PhD recipients significantly exceeds that of other professional degree recipients except for medicine. Superior job satisfaction for STEM PhDs results almost entirely from employment in tenured academic positions. 55 percent of STEM PhDs working outside the academic sector have similar job satisfaction compared to professional degree recipients but without the economic rewards. This analysis further suggests STEM PhDs would not have higher job satisfaction if they had completed degrees in medicine or law instead of PhDs. The policy to increase STEM PhD employment in the US economy has focused on supply. The findings of this paper indicate that a demand-side focus may be a more effective policy and that the future STEM PhD supply will be largely driven by the availability of full-time tenure-track academic job openings.

Optimisation of triangulation based optical profilometers utilising digital video projection technology

Fast, high precision and automated optical noncontact surface profile and shape measurement has been an extensively studied research area due to its many potential applications including 3D sensing, industrial monitoring, mechanical engineering, medicine, robotics, machine vision,animation, virtual reality, dressmaking, prosthetics, ergonomics. Among others, structured light approaches including fringe profilometry have proven to be one of the most promising techniques. In such profilometry techniques a structured light pattern, generally composed of parallel lines is projected onto a diffuse surface to be measured and viewed from an offset angle. The observed pattern is distorted by the object in such a way that represents information about the height of the object perpendicular to the plane of observation. The distorted structured light pattern is recorded, commonly by a CCD camera and through computer analysis of the recorded image the object can be recreated in 3D space, typically with a high degree of precision
