Correspondence issued by the General Accounting Office with an abstract that begins "Although pilots and other crew members are currently prohibited from carrying weapons on-board aircraft, the Aviation and Transportation Security Act raises the possibility of arming pilots in the future. In responses to a congressional request, GAO provided information on reasons for and against allowing pilots to carry firearms in the cockpit; questions to be addressed if pilots were armed; and possible alternatives to arming pilots, such as providing them with less than lethal weapons. Proponents' and opponents' views on firearms in the cockpit fall into four categories: the potential effectiveness, risk, and cost-effectiveness of pilots carrying weapons, and policy issues that would arise if pilots were allowed to carry weapons. GAO concluded that without additional research, the potential benefits, risks, and costs of using weapons on aircraft cannot be fully determined."

Correspondence issued by the General Accounting Office with an abstract that begins "Congress limited the Executive Office of the President's use of systems modernization funds until the White House gave Congress a report that included an enterprise architecture, a description of information technology (IT) capital planning and investment control processes, a capital investment plan, and an IT human capital plan. The White House submitted its report to Congress in March 2002. GAO reviewed the report and found progress in the following four areas: (1) developing an officewide blueprint for modernizing its enterprise architecture; (2) defining officewide IT capital planning and investment control processes for implementing the enterprise architecture consistent with best practices; (3) correcting existing system problems and introducing infrastructure upgrades consistent with its defined technical rules and definitions; and (4) facilitating ongoing and planned efforts to complete the enterprise architecture, expand the capital planning and investment process, and manage the implementation of its fiscal year 2002 and 2003 capital investment plans. The White House has also begun using effective IT human capital management practices. Theses efforts should be considered a work in progress rather than a completed task. Therefore, the success of the White House's modernization effort depends on …

Testimony issued by the General Accounting Office with an abstract that begins "Since the terrorist attacks on September 11, 2001, and the subsequent anthrax incidents, there has been concern about the ability of the federal government to prepare for and coordinate an effective public health response given the broad distribution of responsibility for that task at the federal level. More then 20 federal departments and agencies carry some responsibility for bioterrorism preparedness and response. The President's proposed Homeland Security Act of 2002 would bring many of these federal entities with homeland security responsibilities--including public health preparedness and response--into one department to mobilize and focus assets and resources at all levels of government. The proposed reorganization has the potential to assist in the coordination of public health preparedness and response programs at the federal, state, and local levels. There are concerns, however, about the proposed transfer of control of public health assistance programs that have both basic public health and homeland security functions from Health and Human Services to the new department. Transferring control over these programs, including priority setting, to the new department has the potential to disrupt some programs critical to basic public health responsibilities. The President's proposal is …

A letter report issued by the General Accounting Office with an abstract that begins "Identity theft or identity fraud generally involves "stealing" another person's personal identifying information--such as Social Security Number (SSN), date of birth, and mother's maiden name--and then using the information to fraudulently establish credit, run up debt, or take away existing financial accounts. The Identity Theft and Assumption Deterrence Act of 1998 made identity theft a separate crime against the person whose identity was stolen, broadened the scope of the offense to include the misuse of information as well as documents and provided punishment--generally a fine or imprisonment or both. GAO found no comprehensive or centralized data on enforcement results under the federal Identity Theft Act. However, according to a Deputy Assistant Attorney General, federal prosecutors are using the 1998 federal law. As with the federal act, GAO found no centralized or comprehensive data on enforcement results under state identity theft statutes. However, officials in the 10 states selected for study provided examples of actual investigations or prosecutions under these statutes. Generally, the prevalence of identity theft and the frequently multi- or cross-jurisdictional nature of such a crime underscore the importance of promoting cooperation or coordination among …

A letter report issued by the General Accounting Office with an abstract that begins "On April 9, 2002, GAO testified on the Internal Revenue Service's (IRS) fiscal year 2003 budget request. Although IRS had adequately justified its $450 million Business Systems Modernization request, it did not develop its $1.63 billion information systems operations and maintenance request in accordance with the best practices of leading private- and public-sector information technology organizations. See GAO-02-580T."

A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed whether the Office of Federal Housing Enterprise Oversight (OFHEO) should incorporate new business assumptions into the stress test used to establish risk-based capital requirements. The stress test is designed to estimate, for a 10-year period, how much capital the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac) would be required to hold to withstand potential economic shocks, such as sharp movements in interest rates or adverse credit conditions. Incorporating new business assumptions into the stress test would mean specifying details about the types and quality that would be acquired during the 10-year stress period, the types of funding that would be used to acquire such mortgages, and other operating and financial strategies that would be implemented by Fannie Mae's and Freddie Mac's managements. GAO found that data for the enterprises show that new business conducted over a 10-year period accounts for a large share of their on- and off-balance sheet holdings of assets and liabilities at the end of each 10-year period. Because new business represents such a large share of enterprise holdings over time, it would …

A letter report issued by the General Accounting Office with an abstract that begins "In response to concerns about the length of time children were spending in foster care, Congress enacted the Adoption and Safe Families Act of 1997 (ASFA). The act contained two key provisions intended to help states more quickly move the more than 800,000 children estimated to be in foster care each year to safe and permanent homes. One of these provisions, referred to as "fast track," allows states to bypass efforts to reunify families in certain egregious situations. The other provision, informally called "15 of 22," requires states to file a petition to terminate parental rights when a child has been in foster care for 15 of the most recent 22 months. Although the number of adoptions has increased by 57 percent since the act was enacted, changes in other foster care outcomes and the characteristics of children in foster care cannot be identified due to the lack of comparable pre- and post-ASFA data. Although data on states' use of the act's two key performance provisions are limited, some states described circumstances that hinder their use. Survey data suggest that a few states used the fast …

A letter report issued by the General Accounting Office with an abstract that begins "In November 1992, the Department of Defense (DOD) issued a policy requiring systems to be interoperable. In May 2000, the department began to enforce this policy for telecommunications (telecom) switches, requiring them to be tested and certified for interoperability before being installed within the DOD network. DOD does not have a well-defined process, including clear requirements, for certifying and authorizing telecom switches. The process is not fully documented, current, or complete and DOD has not applied its telecom switch certification and authorization process consistently across vendors, and sometimes violated policy. DOD's application of its telecom switch certification and authorization process is influencing vendors' plans for competing for the department's business. One of five vendors GAO interviewed stated that it has stopped doing business with DOD for economic reasons. Within DOD, positions are mixed on the impact of the department's interoperability goal on competition."

Correspondence issued by the General Accounting Office with an abstract that begins "Under the Department of Housing and Urban Development's (HUD) Community Development Block Grant (CDBG) program, entitlement communities--also called grantees--receive funds that they can spend to support specific community development activities, such as rehabilitating housing, improving public facilities, and providing public services. Most grantees are prohibited by statute from spending more than 15 percent of their CDBG funding on public service activities, such as child care, health care, and crime prevention. However, in the aftermath of the 1992 Los Angeles civil unrest, Congress gave an exemption from this statutory cap to two grantees--the City of Los Angeles and the County of Los Angeles--allowing them to spend up to 25 percent of their funds on public services. In December 2001, the exemption was extended through 2003. Between 1993 and 2001, the City of Los Angeles spent between 20 and 25 percent of its CDBG funding to support public service activities, while the County of Los Angeles spent between 9 and 20 percent. According to HUD data for 1999 through 2001, the city and county used a majority of their public service funding to support general public services and either youth …

In this study, a genetics-based method is used to truncate acetyl-coenzyme A synthase from Clostridium thermoaceticum (ACS), an alpha2beta2 tetrameric 310 kda bifunctional enzyme. ACS catalyzes the reversible reduction of CO2 to CO and the synthesis of acetyl-CoA from CO (or CO2 in the presence of low-potential reductants), CoA, and a methyl group bound to a corrinoid-iron sulfur protein (CoFeSP). ACS contains 7 metal-sulfur clusters of 4 different types called A, B, C, and D. The B, C, and D clusters are located in the 72 kda beta subunit while the A-cluster, a Ni-X-Fe4S4 cluster that serves as the active site for acetyl-CoA synthase activity, is located in the 82 kda alpha subunit. The extent to which the essential properties of the cluster, including catalytic, redox, spectroscopic, and substrate-binding properties, were retained as ACS was progressively truncated was determined. Acetyl-CoA synthase catalytic activity remained when the entire alpha subunit was removed, as long as CO, rather than CO2 and a low-potential reductant, was used as a substrate. Truncating an {approx} 30 kda region from the N-terminus of the alpha subunit yielded a 49 kda protein that lacked catalytic activity but exhibited A-cluster-like spectroscopic, redox, and CO binding properties. Further truncation …

Testing was performed to define technical issues that may impact long-term viability of the segregation strategy for processing and storing evaporator concentrates. The primary concern is increased potential for nuclear criticality from uranium accumulation. This statistically designed testing examines the fate of uranium when Al and Si rich concentrates are either purposefully or inadvertently combined.

The Gordon Research Conference (GRC) on Chemical Physics Summer School was held at Roger Williams University, Bristol, RI. Emphasis was placed on current unpublished research and discussion of the future target areas in this field.

Three short Nb{sub 3}Sn dipole models based on a single-bore cos-theta coil and a cold iron yoke have been fabricated and tested at Fermilab. This paper summarizes the results of magnetic measurements in those models. The geometrical harmonics, coil magnetization effects, cable eddy currents with and without a stainless steel core, and the ''snap-back'' effect at injection are presented.

A high beam power in the proposed Fermilab Proton Drivers--1.2 MW in 16-GeV PD-I and 0.48 MW in 8-GeV PD-II--implies serious constraints on beam losses in these machines. Only with a very efficient beam collimation system can one reduce uncontrolled beam losses in the machine to an allowable level. The entire complex must be well shielded to allow acceptable hands-on maintenance conditions in the tunnel and a non-controlled access to the outside shielding at normal operation and accidental beam loss. Collimation and shielding performances are calculated and compared for both Proton Drivers.

The overall goal of the proposed research is to provide an improved understanding and predictive capability of the mechanisms that allow metal-reducing bacteria to be effective in the bioremediation of redox sensitive toxic metals and radionuclides. The study is motivated by the likelihood that subsurface metal-reducing bacteria can be stimulated to effectively alter the redox state of contaminants so that they are immobilized in situ for long time periods. The work described in this proposal will advance the technological and scientific needs associated with the long-term management of the enormous inground inventories of Cr, U, Tc, and Co present at numerous DOE installations throughout the country. The objectives of our project are to (1) develop an improved understanding and predictive capability of the rates and mechanisms controlling microbially mediated reduction of toxic metals and radionuclides in heterogeneous field settings, (2) quantify the impacts of hydrological and geochemical processes on the effectiveness of indigenous microorganisms to transform and immobilize radionuclides and metals in situ, (3) provide an improved understanding of the importance of microbial consortia interactions in the bacterial immobilization of radionuclides and toxic metals, and (4) determine intrinsic bioreduction rate parameters to improve our generic predictive capability of in situ …

Final report describing laboratory, pilot scale and production scale evaluation of advanced oxidation systems for emissions and cost reduction in metal casting green sand systems.

The issue of magnetic orientation transitions in thin films combines interesting physics and importance for applications. We study the magnetic transition and phase diagram of a 0.1{micro}m thick (YLaGd){sub 3}(FeGa){sub 5}O{sub 12} films grown on GGG substrate by liquid phase epitaxy. Observed transitions are compared with those in BiGa:TmIG thin films, studied in previous work by one of the authors. A general picture of orientation transitions in thin films of substituted YIG is discussed.

A five-year, large- and small-scale, static and dynamic experimental research program, in which more than 700 tests were conducted, has demonstrated that unreinforced masonry infills are more ductile and resist lateral loads more effectively than anticipated by conventional code procedures. The tests were conducted both in the laboratory and on existing structures at the Department of Energy's Y-12 National Security Complex. The experimental data indicate that the combination of a steel frame and infill material efficiently resists lateral loads--the infilling provides significant lateral stiffness while the surrounding frame adds ductility and confinement to the overall system. The results from approximately 25 moderate- and full-scale tests on infills showed that with simulated seismic loads, the frames confined the masonry, and the load-carrying capacity of the infill was considerably above the load that caused initial cracking. This finding was a significant departure from classical code approaches that assumed first cracking to be failure of an unreinforced masonry wall. The experimental program, performed for the US Department of Energy, consisted of the following large-scale tests on infills: in situ airbag pressure testing, shake-table tests, and the application of quasi-static in-plane and out-of-plane drift loads. This paper provides a summary of the overall experimental …
