Previous studies have demonstrated that gravitational radiation reliably encodes information about the natural emission direction of the source (e.g., the orbital plane). In this paper, we demonstrate that these orientations can be efficiently estimated by the principal axes of L (aL b), an average of the action of rotation group generators on the Weyl tensor at asymptotic infinity. Evaluating this average at each time provides the instantaneous emission direction. Further averaging across the entire signal yields an average orientation, closely connected to the angular components of the Fisher matrix. The latter direction is well-suited to data analysis and parameter estimation when the instantaneous emission direction evolves significantly. Finally, in the time domain, the average L (aL b) provides fast, invariant diagnostics of waveform quality. © 2011 American Physical Society.

Southern University is centering itself at the forefront of the sustainability frontier by engaging in the development of the next generation of sustainable materials, energy and technologies. Basic sciences that will lay the foundation for development of this initiative within the SU STEM enterprise are Agricultural Sciences, Engineering, and Physical Sciences, which will combine to support three primary research thrusts - Materials Science & Energy Technologies; Biomass Conversion, Biofuels & Bioenergy; and Climate Change & Environmental Impact. Computational Science & Information Technology will serve as an undergirding connection throughout.

The ACE Implementation project entitled: The New Energy Workforce - Sustainable Materials, Energy & Technology, will develop concentrations within the Colleges of Agricultural Sciences, Engineering, and Sciences, and create an interdisciplinary international degree program that integrates research, academics and experiential learning toward resolving sustainability issues faced by Louisiana, this nation and the global community.

The project will expose undergraduate students to sustainable materials, energy, and technologies through an interdisciplinary dual-degree curriculum that integrates academics, research and global engagement with international universities; assemble interdisciplinary teams of international scientists and engineers to identify solutions to sustainability challenges affecting the global community; and engage in interdisciplinary sustainable materials, energy and technologies research activities with special emphasis on clean and renewable resources suitable for commercialization and replication. Forging collaborative partnerships that emphasize student and faculty exchange, joint research foci, joint course offerings and joint academic degree programs will promote scientific and technological understanding within the global STEM Enterprise.

This award is one component of a collaborative effort to fund the Laser Interferometer Gravitational-wave Observatory (LIGO) Science Education Center Partnership between Southern University in Baton Rouge (SUBR), LA, the LIGO Livingston site in Livingston, La, through the Baton Rouge Area Foundation (BRAF), and the Exploratorium. The managing institution for LIGO itself is California Institute of Technology. The project is the continuation of the LIGO Science Education Center Partnership focused on scientific outreach to the general public, teacher training, and teacher education focused on LIGO activities in Louisiana. A previous award helped create the SEC building, with a classroom and a large exhibit hall, with exhibits developed by the Exploratorium and staffed by SUBR student docents and a (separately funded) professional staff. The multilayered partnership of HBCUs, a cutting edge research facility and a renowned informal science center created a model for future partnerships. With the expansion of this partnership the model is extended, and research on the effects of these extensive partnerships can provide information for future attempts at leveraging the resources of research laboratories for educational purposes.

This project will use the LIGO-SEC Partnership to amplify and nurture a Science, Technology, Engineering, Education and Mathematics (STEEM) pipeline that taps into under-represented audiences and engages them in techniques that encourage students to advance their education in STEEM fields. The docent program and the teacher programs will increase participation of under-represented audiences within the STEEM fields. The docent program will train between sixty and eighty under-represented STEEM majors to become community ambassadors in conjunction with LIGO Science Education Centers outreach program, and the docents will interact with between 12,500 and 5,000 participants. The teacher professional development activities target high-need areas in New Orleans and Baton Rouge. The activities will develop around 250 teachers familiarity with engineering design processes and underlying science concepts. These teachers will create and build interactive science activities to use in the classroom to engage with students. Graduate students will conduct new research in the use of inquiry and informal science methods within the formal (School) and informal (LIGO-SEC) environments. The graduate students dissertations will contribute to the literature on Informal Science Education. The project is guided by an on-going evaluation.

The project will apply a tested methodological approach--a multi-metric approach to assess the impact of STEM instructional multimedia on undergraduate teaching and learning-- to the subject matter of electronic health records (EHR). The project deploy three comprehensive multimedia case studies that introduce undergraduate STEM students to electronic health records and assess the effect of this approach on student learning, including impact on higher order cognitive skills. Three constructs and criteria will be used to assess students actual learning: 1) Learning-Driven factor, 2) Content-Driven factor, and 3) Higher-Order Cognitive Skills factor. Three inter-related qualitative and quantitative matrices will be developed to assess students perceived learning (Perceived Learning Matrix), actual learning (Actual Learning Outcome Matrix), and learning processes (Learning Process Matrix). The innovative multimedia instructional approach developed in this project is expected to give students first-hand observational experience of EHR operations and can be used to teach other information technology topics where visualization is very important as opposed to traditional text book lecture on emerging technology issues.

The research topic of this IRES program addresses the possibility of designing the urban ecosystem to deal with the negative effects of climate change. The proposed program will send students from Southern University and Louisiana State University to China to conduct collaborative research with the Chinese Academy of Sciences (CAS) Institute of Applied Ecology and Southern China Botanical Garden, and the Beijing Forestry Institute, The research will be directed at four general topics: Modeling the impact of global warming and urbanization on natural resources; Combined effects of elevated levels of carbon dioxide and ozone on urban forests; Carbon storage and sequestration by urban forests; and Response of soil carbon dynamics to long-term nitrogen deposition in a tropical forest at the urban-rural interface.

Each year four undergraduates and four graduate students will participate in the research activities in China. The project focuses on a very topical area of interest (i.e. sustainability), which has growing importance considering the worlds current dependence on fossil fuels and the concomitant rise in greenhouse-gas levels. It involves a unique collaboration between the U.S. universities and the institutions in China. The substance of the research efforts should lead to better understanding of complex environmental dynamics in urban settings, which should have application in the U.S. and China as in other parts of the world and promote effective mitigation strategies. Also, the involvement of an HBCU in the IRES program should make a positive contribution to human-resource development in this field.
