An x-ray probe of laser-aligned molecules

We demonstrate a hard x-ray probe of laser-aligned small molecules. To align small molecules with optical lasers, high intensities at nonresonant wavelengths are necessary. We use 95 ps pulses focused to 40 mum from an 800 nm Ti:sapphire laser at a peak intensity of 10^12 W/cm^2 to create an ensemble of aligned bromotrifluoromethane (CF3Br) molecules. Linearly polarized, 120 ps x-ray pulses, focused to 10 mum, tuned to the Br 1s --> sigma* pre-edge resonance at 13.476 keV, probe the ensemble of laser-aligned molecules. The demonstrated methodology has a variety of applications and can enable ultrafast imaging of laser-controlled molecular motions with Angstrom-level resolution.Comment: 4 pages, 4 figures, RevTeX4, corrected typo

Accountability and Single-Sex Schooling: A Collision of Reform Agendas

This ethnographic study documents how accountability measures skewed the implementation of gender equity reform at one California public middle school serving low-income students of color. In creating single-sex classes throughout the school, the Single Sex Academy (SSA) became the largest public experiment with single-sex schooling in the country, but pressure to raise its standardized test scores diverted the school away from the exploration and implementation of the gender reform. The chronicle of SSA is particularly relevant in light of (a) a recent call to relax Title IX standards and increase the numbers of public single-sex classes and schools, and (b) the provision of monies mandated by the No Child Left Behind Act of 2001 for single-sex classes and schools, along with the act\u27s imposition of accountability standards and testing

Developing the Next Generation of Education Researchers: UCLA's Experience with the Spencer Foundation Research Training Grant

Background/Context In the early 1990s, the Spencer Foundation instituted an Institutional Research Training Grant (RTG) program to improve the preparation of the next generation of education researchers. UCLA received an RTG in the first round of competition. Purpose/Objective/Research Question/Focus of Study UCLA's Spencer RTG program sought to develop excellent researchers focused on educational issues associated with urban students of color and students with special needs. An evaluation was conducted to learn more about the experiences and career paths of participating Spencer students, the value added by RTG program participation, and institutional changes associated with the RTG program. Population/Participants/Subjects Participants were all 52 UCLA education PhD students who received a Spencer RTG Fellowship in the first 9 years of the program, 52 matched comparison students, and 10 Department of Education faculty. Intervention/Program/Practice Spencer and comparison students participated in the same PhD program courses and requirements, mentoring/apprenticeship model, research practica, and research apprenticeship courses. Spencer students in addition had 3 years of full financial support, came from all areas of the Department of Education, participated in a special seminar every 2 weeks for 3 years, had a personal professional development fund, and were offered many opportunities to network with students and faculty from other Spencer programs. Research Design This in-house evaluation employed multiple approaches. Institutional data provided information about RTG program goals and activities and student characteristics and performance. A Web-based questionnaire and individual interviews provided quantitative and qualitative data about the performance and opinions of all 52 Spencer students and 52 comparison students. Dissertations were scored for engagement with Spencer program areas of emphasis. Individual faculty interviews provided opinions about the RTG program itself and its implications for the PhD program. Findings/Results Nearly all students were successful and benefited from courses, mentor-ship, and opportunities. Spencer students benefited particularly from financial freedom to pursue specific research interests and opportunities for networking and support. They valued highly interacting with PhD students from the Department of Education's entire range of epistemologies and research traditions. They were seen as an elite group, particularly groomed for academic positions. Significantly more Spencer than comparison graduates were in professional positions in which engaging in education research was highly valued. Conclusions/Recommendations The study underlines the following contributions: value of the apprenticeship/mentoring model; strengthening of sites for exploring diverse research traditions and epistemologies; value of belonging to local and national communities of practice; utility of multiyear funding packages; and enhanced faculty interaction around improved research preparation. </jats:sec
