2000 Census: Coverage Evaluation Matching Implemented as Planned, but Census Bureau Should Evaluate Lessons Learned

A letter report issued by the General Accounting Office with an abstract that begins "The U.S. Census Bureau conducted the Accuracy and Coverage Evaluation (ACE) survey to estimate the number of people missed, counted more than once, or otherwise improperly counted in the 2000 Census. On the basis of uncertainty in the ACE results, the Bureau's acting director decided that the 2000 Census tabulations should not be adjusted in order to redraw the boundaries of congressional districts or to distribute billions of dollars in federal funding. Although ACE was generally implemented as planned, the Bureau found that it overstated census undercounts because of an error introduced during matching operations and other uncertainties. The Bureau concluded that additional review and analysis of these uncertainties would be needed before the data could be used. Matching more than 1.4 million census and ACE records involved the following four phases, each with its own matching procedures and multiple layers of review: computer matching, clerical matching, field follow-up, and clerical matching. The Bureau applied quality assurance procedures to each phase of person matching. Because the quality assurance procedures had failure rates of less than one percent, the Bureau reported that person matching quality assurance was …

[3H]Azidodantrolene photoaffinity labeling, synthetic domain peptides and monoclonal antibody reactivity identify the dantrolene binding sequence on RyR1 (open access)

[3H]Azidodantrolene photoaffinity labeling, synthetic domain peptides and monoclonal antibody reactivity identify the dantrolene binding sequence on RyR1

Dantrolene is a drug that suppresses intracellular Ca2+ release from sarcoplasmic reticulum in normal skeletal muscle and is used as a therapeutic agent in individuals susceptible to malignant hyperthermia. Though its precise mechanism of action has not been elucidated, we have identified the N-terminal region (amino acids 1-1400) of the skeletal muscle isoform of the ryanodine receptor (RyR1), the primary Ca2+ release channel in sarcoplasmic reticulum, as a molecular target for dantrolene using the photoaffinity analog [3H]azidodantrolene(1). Here, we demonstrate that heterologously expressed RyR1 retains its capacity to be specifically labeled with [3H]azidodantrolene,indicating that muscle specific factors are not required for this ligand-receptor interaction. Synthetic domain peptides of RyR1, previously shown to affect RyR1 function in vitro and in vivo, were exploited as potential drug binding site mimics and used in photoaffinity labeling experiments. Only DP1 and DP1-2, peptide s containing the amino acid sequence corresponding to RyR1 residues 590-609, were specifically labeled by [3H]azidodantrolene. A monoclonal anti-RyR1 antibody which recognizes RyR1 and its 1400 amino acid N-terminal fragment, recognizes DP1 and DP1-2 in both Western blots and immunoprecipitation assays, and specifically inhibits [3H]azidodantrolene photolabeling of RyR1 and its N-terminal fragment in sarcoplasmic reticulum. Our results indicate that synthetic domain …

Air Traffic Control: FAA Needs to Better Prepare for Impending Wave of Controller Attrition (open access)

Air Traffic Control: FAA Needs to Better Prepare for Impending Wave of Controller Attrition

A chapter report issued by the General Accounting Office with an abstract that begins "Thousands of the Federal Aviation Administration (FAA) controllers will soon be eligible to retire because of extensive hiring in the 1980's to replace striking air traffic controllers. Although the exact number and timing of the controllers' departures has not been determined, attrition scenarios developed by both FAA and GAO indicate that the total attrition will grow substantially in both the short and long term. As a result, FAA will likely need to hire thousands of air traffic controllers in the next decade to met increasing traffic demands and to address the anticipated attrition of experienced controllers, predominately because of retirement. FAA has yet to developed a comprehensive human capital workforce strategy to address its impending controller needs. Rather, FAA's strategy for replacing controllers is generally to hire new controllers only when current, experienced controllers leave. This does not take into account the potential increases in future hiring and the time necessary to train replacements. In addition, there is uncertainty about the ability of FAA's new aptitude test to identify the best controller candidates. Further, FAA has not addressed the resources that may be needed at its …

Alternative Field Methods to Treat Mercury in Soil (open access)

Alternative Field Methods to Treat Mercury in Soil

The Department of Energy (DOE) currently has mercury (Hg) contaminated materials and soils at the various sites. Figure 1-1 (from http://www.ct.ornl.gov/stcg.hg/) shows the estimated distribution of mercury contaminated waste at the various DOE sites. Oak Ridge and Idaho sites have the largest deposits of contaminated materials. The majorities of these contaminated materials are soils, sludges, debris, and waste waters. This project concerns treatment of mercury contaminated soils. The technology is applicable to many DOE sites, in-particular, the Y-12 National Security Complex in Oak Ridge Tennessee and Idaho National Engineering and Environmental Laboratory (INEEL). These sites have the majority of the soils and sediments contaminated with mercury. The soils may also be contaminated with other hazardous metals and radionuclides. At the Y12 plant, the baseline treatment method for mercury contaminated soil is low temperature thermal desorption (LTTD), followed by on-site landfill disposal. LTTD is relatively expensive (estimated cost of treatment which exclude disposal cost for the collect mercury is greater than $740/per cubic yard [cy] at Y-12), does not treat any of the metal or radionuclides. DOE is seeking a less costly alternative to the baseline technology. As described in the solicitation (DE-RA-01NT41030), this project initially focused on evaluating cost-effective in-situ …

Alternative Field Methods to Treat Mercury in Soil (open access)

Alternative Field Methods to Treat Mercury in Soil

U.S. Department of Energy (DOE) used large quantities of mercury in the uranium separating process from the 1950s until the late 1980s in support of national defense. Some of this mercury, as well as other hazardous metals and radionuclides, found its way into, and under, several buildings, soil and subsurface soils and into some of the surface waters. Several of these areas may pose potential health or environmental risks and must be dealt with under current environmental regulations. DOE's National Energy Technology Laboratory (NETL) awarded a contract ''Alternative Field Methods to Treat Mercury in Soil'' to IT Group, Knoxville TN (IT) and its subcontractor NFS, Erwin, TN to identify remedial methods to clean up mercury-contaminated high-clay content soils using proven treatment chemistries. The sites of interest were the Y-12 National Security Complex located in Oak Ridge, Tennessee, the David Witherspoon properties located in Knoxville, Tennessee, and at other similarly contaminated sites. The primary laboratory-scale contract objectives were (1) to safely retrieve and test samples of contaminated soil in an approved laboratory and (2) to determine an acceptable treatment method to ensure that the mercury does not leach from the soil above regulatory levels. The leaching requirements were to meet the …

Anomalous momentum dependence of the quasiparticle scattering ratein overdoped Bi2Sr2CaCu2O8 (open access)

Anomalous momentum dependence of the quasiparticle scattering ratein overdoped Bi2Sr2CaCu2O8

The question of the anisotropy of the electron scattering in high temperature superconductors is investigated using high resolution angle-resolved photoemission data from Pb-doped Bi2Sr2CaCu2O8(Bi2212) with suppressed superstructure. The scattering rate of low energy electrons along two bilayer split pieces of the Fermi surface is measured (via the quasiparticle peak width), and no increase of scattering towards the antinode (Pi,0) region is observed, contradicting the expectation from Q=(Pi, Pi) scattering. The results put a limit on the effects of Q=(Pi, Pi) scattering on the electronic structure of this overdoped superconductor with still very high Tc.

APDS: Autonomous Pathogen Detection System

An early warning system to counter bioterrorism, the Autonomous Pathogen Detection System (APDS) continuously monitors the environment for the presence of biological pathogens (e.g., anthrax) and once detected, it sounds an alarm much like a smoke detector warns of a fire. Long before September 11, 2001, this system was being developed to protect domestic venues and events including performing arts centers, mass transit systems, major sporting and entertainment events, and other high profile situations in which the public is at risk of becoming a target of bioterrorist attacks. Customizing off-the-shelf components and developing new components, a multidisciplinary team developed APDS, a stand-alone system for rapid, continuous monitoring of multiple airborne biological threat agents in the environment. The completely automated APDS samples the air, prepares fluid samples in-line, and performs two orthogonal tests: immunoassay and nucleic acid detection. When compared to competing technologies, APDS is unprecedented in terms of flexibility and system performance.

Applying a decision process for long-term stewardship planning at a US Department of Energy site. (open access)

Applying a decision process for long-term stewardship planning at a US Department of Energy site.

Long-term stewardship (LTS) can be defined as the system of activities needed to protect human health and the environment from hazards left remaining at a site as a result of a cleanup decision. Although the general consensus has been that remediation decisions and LTS decisions should be made conjointly, the general practice has been to separate them. This bifurcation can result in LTS plans that are difficult to implement and enforce and disproportionately costly for the benefit they provide. Worse still, they can be ineffective and result in harmful exposures to humans and the environment. Sites that have not yet made cleanup decisions and that can still integrate LTS planning into that decision making would benefit from a process built on a systematic review of the LTS risks and costs associated with remedial alternatives that include allowing on-site residual contamination. Sites that must develop LTS plans in response to previously determined cleanup decisions are even more in need of a process that involves close scrutiny of the risks and costs of possible LTS plan components. An LTS planning decision process usable by both categories of sites has been developed and is being used at the US Department of Energy (DOE) …

Assessing Groundwater Model Uncertainty for the Central Nevada Test Area (open access)

Assessing Groundwater Model Uncertainty for the Central Nevada Test Area

The purpose of this study is to quantify the flow and transport model uncertainty for the Central Nevada Test Area (CNTA). Six parameters were identified as uncertain, including the specified head boundary conditions used in the flow model, the spatial distribution of the underlying welded tuff unit, effective porosity, sorption coefficients, matrix diffusion coefficient, and the geochemical release function which describes nuclear glass dissolution. The parameter uncertainty was described by assigning prior statistical distributions for each of these parameters. Standard Monte Carlo techniques were used to sample from the parameter distributions to determine the full prediction uncertainty. Additional analysis is performed to determine the most cost-beneficial characterization activities. The maximum radius of the tritium and strontium-90 contaminant boundary was used as the output metric for evaluation of prediction uncertainty. The results indicate that combining all of the uncertainty in the parameters listed above propagates to a prediction uncertainty in the maximum radius of the contaminant boundary of 234 to 308 m and 234 to 302 m, for tritium and strontium-90, respectively. Although the uncertainty in the input parameters is large, the prediction uncertainty in the contaminant boundary is relatively small. The relatively small prediction uncertainty is primarily due to the …

Beam based alignment at the KEK accelerator test facility

The KEK Accelerator Test Facility (ATF) damping ring is a prototype low emittance source for the NLC/JLC linear collider. To achieve the goal normalized vertical emittance {gamma}{var_epsilon}{sub {gamma}} = 20 nm-rad, magnet placement accuracy better than 30 mm must be achieved. Accurate beam-based alignment (BBA) is required. The ATF arc optics uses a FOBO cell with two horizontally focusing quadrupoles, two sextupoles and a horizontally defocusing gradient dipole, all of which must be aligned with BBA. BBA at ATF uses the quadrupole and sextupole trim windings to find the trajectory through the center of each magnet. The results can be interpreted to assess the accuracy of the mechanical alignment and the beam position monitor offsets.

Calorimeter Process Variable Archiving

These steps were taken to maintain weekly archives: (1) Friday morning you stop the archiver and wait for it to finish writing data (the lock file will be removed from the directory); (2) move the current archive information to a PC via FTP; (3) remove all previous archive information in the previous directory; (4) move the current archive into the previous directory; (5) start a new archive; (6) burn a CDROM of the archive; and (7) copy the current archive to a specific directory. There are 2 ways to check if the Calorimeter Archiver is running, either through the WEB based front end or directly from a command line. Once the archiver is running it can be monitored from a WEB page. This only works with a browser launched from the online machine running the archiver. Each time the browser is reloaded there should be an update reported in the last write check field. You might have to wait a few minutes to see the update. Calorimetry currently takes readings every (300 sec.) 5 minutes. The second method to verify the archiver is running is to issue a command from a Linux cluster machine.

Campaign Finance: Constitutional and Legal Issues of Soft Money

Soft money is a major issue in the campaign finance reform debate because such funds are generally unregulated and perceived as resulting from a loophole in the Federal Election Campaign Act (FECA). More specifically, soft money is considered to be funds that are raised and spent according to applicable state laws, which FECA prohibits from being spent directly on federal elections, but that may have an indirect influence on federal elections. This Issue Brief discusses three major types of soft money: political party soft money, corporate and labor union soft money, and soft money used for issue advocacy communications.
