Book Description
This is the second annual progress on the three-year Large Experiment Data Analysis Collaboration DOE grant DE-FGO2-92ER54139, which succeeded a previous four-year grant under the same grant number. This year most of the collaboration effort shifted from being with the TFTR program, to being with the DIII-D program, and most new research focused on the properties, causes and possible amelioration of neoclassical tearing modes. In addition, our studies of nonlocal electron heat transport in TFTR have attracted wider attention, and are now being transferred to similar research on DIII-D.

Book Description
Studies of neoclassical tearing modes have remained the dominant area of research on this grant. Our major role in their development was recognized through an invited paper at the 1998 Pittsburgh DPP-APS meeting and through our inclusion as coauthors on some major TFTR and DIII-D papers. During this past year, prior work has been published on DIII-D experiment-motivated theories of stabilization of tearing modes via localized current-drive and heating and on effects of geometry on these modes (elongation and triangularity effects should be small in DIII-D), and on experimental studies of the imposed beta limits and direct, internal measurements of the critical classical tearing mode stability parameter (delta-prime). Also, linear and nonlinear theory and computation studies of classical tearing modes via the ''almost ideal MHD'' constraint has been the subject of a number of meeting presentations and has recently been published. Recent work has been concerned with developing a theoretical model for the magnitude of seed island perturbations due to, geometrically coupled magnetic perturbations (e.g., ELMS or sawtooth crashes) and simulations thereof, exploring the effects of external perturbations, development of a simulation model for flow shear effects, studies of the effect of the combination of flow shear and perpendicular viscosity in distorting the magnetic island structure and producing the phase shift in ECE signals across a magnetic island, simulations of feedback stabilization of tearing mode islands, and exploring what aspects of tearing modes need to be calculated for DIII-D. Our continuing role in transient transport and nonlocal electron heat transport was recognized by an invited paper at the June 1997 EPS Berchtesgaden meeting which was published this past year. In addition, further details of nonlocal electron heat transport, primarily on TFTR, have been the subject of meeting presentations and are being published. Since Dr. Kissick left this research group for UCLA in April 1998 and Prof. Callen is in the process of transferring leadership of the TTF Transient Transport Working Group to Prof. Gentle (U. Texas), it is anticipated that this grant research area will be substantially diminished in the future. Stimulated in large part by the excellent internal fluctuation diagnostics (primarily ECE and BES) for studying MHD modes in the interior of DIII-D, we have begun work in a new area: disruption precursors induced by MHD modes being driven slowly through their ideal stability boundaries. In particular, we have constructed a new model for the temporal development of such precursors and shown that it provides a very good fit to DIII-D data. Also, we are in the process of developing codes for comparing the spatial profile of the disruption precursors with those predicted from the GATO ideal MHD instability code.

Book Description
Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Book Description
Strengthen programs of family and community engagement to promote equity and increase student success! When schools, families, and communities collaborate and share responsibility for students′ education, more students succeed in school. Based on 30 years of research and fieldwork, the fourth edition of the bestseller School, Family, and Community Partnerships: Your Handbook for Action, presents tools and guidelines to help develop more effective and more equitable programs of family and community engagement. Written by a team of well-known experts, it provides a theory and framework of six types of involvement for action; up-to-date research on school, family, and community collaboration; and new materials for professional development and on-going technical assistance. Readers also will find: Examples of best practices on the six types of involvement from preschools, and elementary, middle, and high schools Checklists, templates, and evaluations to plan goal-linked partnership programs and assess progress CD-ROM with slides and notes for two presentations: A new awareness session to orient colleagues on the major components of a research-based partnership program, and a full One-Day Team Training Workshop to prepare school teams to develop their partnership programs. As a foundational text, this handbook demonstrates a proven approach to implement and sustain inclusive, goal-linked programs of partnership. It shows how a good partnership program is an essential component of good school organization and school improvement for student success. This book will help every district and all schools strengthen and continually improve their programs of family and community engagement.

Book Description
Describes major shortcomings in the implementation of U.N. General Assembly resolutions designed to protect the deep-ocean from the destructive impact of fishing. This is the first comprehensive scientific review of the mgmt. of deep-sea fishing on the high seas globally, this report examines the data available from Regional Fisheries Management Organization (RFMOs), the bodies tasked with implementing the U.N. resolutions. It concludes that ¿RFMOs are failing to manage deep-sea bottom fisheries on the high seas sustainably with respect to target and by-catch species. For most fisheries there is little or no info. on the status of stocks and in many cases we do not even know what is being caught where." Illus. A print on demand report.
