Utah Women and STEM

Employment opportunities in Science, Technology, Engineering, and Math (STEM) sectors in Utah are estimated to reach 101,000 by 2018 (Carnevale, Smith, & Melton, 2011). These jobs are recognized nationwide as being well-compensated and generally recession-proof. Yet Utah women continue to hold a lower percentage of STEM-sec-tor jobs than women nationally; in fact, Utah is ranked last in the United States in terms of the percent of women employed in STEM. In addition, Utah women work in STEM occupations at a rate that is less than half that of Utah men (Institute for Women’s Policy Research (IWPR), 2013). Recognizing the role women must play as an integral part of a strong statewide workforce, Utah educational and civic leaders are working to increase opportunities and pathways for more Utah women to enter and thrive in STEM fields. Such efforts, including educational support and labor force incentives, will allow women to have greater success in their intellectual and financial health and overall well-being. This research report reviews three key areas: 1. Current STEM employment data in Utah and nationwide, 2. Possible explanations for the persistent gender gap in STEM, and 3. A discussion of ongoing efforts in Utah to increase female participation and success in STEM fields

Electronic structure, linear, nonlinear optical susceptibilities and birefringence of CuInX2 (X = S, Se, Te) chalcopyrite-structure compounds

The electronic structure, linear and nonlinear optical properties have been calculated for CuInX2 (X=S, Se, Te) chalcopyrite-structure single crystals using the state-of-the-art full potential linear augmented plane wave (FP-LAPW) method. We present results for band structure, density of states, and imaginary part of the frequency-dependent linear and nonlinear optical susceptibilities. We find that these crystals are semiconductors with direct band gaps. We have calculated the birefringence of these crystals. The birefringence is negative for CuInS2 and CuInSe2 while it is positive for CuInTe2 in agreement with the experimental data. Calculations are reported for the frequency-dependent complex second-order non-linear optical susceptibilities . The intra-band and inter-band contributions to the second harmonic generation increase when we replace S by Se and decrease when we replace Se by Te. We find that smaller energy band gap compounds have larger values of in agreement with the experimental data and previous theoretical calculations.Comment: 17 pages, 6 figure
