The calculation of thin film parameters from spectroscopic ellipsometry data

Spectroscopic ellipsometry (SE) has proven to be a very powerful diagnostic for thin film characterization, but the results of SE experiments must first be compared with calculations to determine thin film parameters such as film thickness and optical functions. This process requires 4 steps: (1) The quantities measured must be specified and the equivalent calculated parameters identified. (2) The film structure must be modeled, where the number of films is specified and certain characteristics of each layer specified, such as whether or not the film is isotropic or anisotropic, homogeneous or graded. (3) The optical functions of each layer must be specified or parameterized. (4) The data must be compared with the calculated spectra, where a quantifiable figure of merit is used for the comparison. The last step is particularly important because without it, no {open_quotes}goodness of fit{close_quotes} parameter is calculated and one does not know whether or not the calculated spectrum fits the data

New Measures of Teacher Turnover Can Reveal Underlying Chronic Staffing Problems in Schools

Teacher quality is one of the most important measures that predicts students’ educational and professional outcomes. But student success can be undermined by teacher turnover. This brief, by PRC faculty research associate Huriya Jabbar and colleagues, describes a typology of teacher turnover measures, including both measures currently in use as well as new measures developed by the authors. These measures illuminate different ways in which staff instability can negatively affect schools.Population Research Cente

IX international conference on Salt Lake research: Research opportunities and management challenges

The 9th International Conference on Salt Lake Research was held 26–30 September 2005 in Western Australia at the Curtin University of Technology, Perth, Australia. One hundred scientists from 10 countries presented research on a diverse array of topics highlighting research findings and opportunities, and management challenges associated with inland saline waters. Major emergent themes of the conference included modeling of ecosystem processes, microbial communities, and features of Western Australian inland saline environments, including current threats, conservation and management

Memorandum to Dr. Tomanek from Bill Jellison

A confidential memo from Bill Jellison regarding the lack of consideration from the athletic department in regards to event schedules. Jellison writes that the staff of Gross Coliseum are upset by the lack of time they are given tom complete set-ups and tear-downs because of the scheduling done by the athletic department. Jellison suggests moving this out of the hands of the department and making them book the space like every other campus organization must.https://scholars.fhsu.edu/buildings/1108/thumbnail.jp
