Fish and Wildlife Service: Federal Assistance Program Is Making Progress in Addressing Previously Identified Concerns (open access)

Fish and Wildlife Service: Federal Assistance Program Is Making Progress in Addressing Previously Identified Concerns

Correspondence issued by the Government Accountability Office with an abstract that begins "The U.S. Fish and Wildlife Service (Service), within the Department of the Interior, uses tax receipts from the sale of certain hunting, fishing, and boating equipment to fund the Wildlife and Sport Fish Restoration programs, which provide grants to state fish and wildlife management agencies to restore, conserve, manage, and enhance wildlife and sport fish resources. The Wildlife Restoration Program was established in 1938 following the passage of the Federal Aid in Wildlife Restoration Act, now referred to as the Pittman-Robertson Wildlife Restoration Act. The Sport Fish Restoration Program was established in 1950 by the Dingell-Johnson Sport Fish Restoration Act. Since their inception, according to the Service, these programs have provided more than $9.5 billion in grants to states and U.S. territories through fiscal year 2005. In 1999 and 2000, GAO identified several instances of mismanagement in these grant programs. Following GAO's work, Congress and the Service acted to improve the programs. In 1999 and 2000, GAO testified on the Service's management and oversight of funds used to administer the Wildlife and the Sport Fish Restoration programs. These testimonies identified several instances of mismanagement of administrative funds. For …

Review of Potential Merger of the Library of Congress Police and/or the Government Printing Office Police with the U.S. Capitol Police (open access)

Review of Potential Merger of the Library of Congress Police and/or the Government Printing Office Police with the U.S. Capitol Police

Correspondence issued by the General Accounting Office with an abstract that begins "There are over 30 police forces currently operating in the District of Columbia, many of which have authority or jurisdiction within the Capitol Hill area. Three of these, the Library of Congress (LOC) Police, the Government Printing Office (GPO) Police, and the U.S. Capitol Police (USCP), are part of the legislative branch. Merging the LOC Police and/or the GPO Police with the USCP is feasible for several reasons. First, although each force has unique responsibilities, their overall missions are similar enough that a merged force could assume both the unique and common responsibilities. Another reason is their common geographic area with overlapping jurisdictions. USCP officials also believe it is possible to merge the other forces into its existing force, and the labor committees of the departments support a merger. Nevertheless, if LOC and/or GPO police were to be merged with the USCP, issues to be addressed include gaining LOC and/or GPO management support, resolving differences in retirement systems, and integrating training and security systems. A merger between the LOC and/or GPO police forces and the USCP would incur significant costs if the intent of a merger is to …

Welfare Reform: Tribal TANF Allows Flexibility to Tailor Programs, but Conditions on Reservations Make It Difficult to Move Recipients into Jobs (open access)

Welfare Reform: Tribal TANF Allows Flexibility to Tailor Programs, but Conditions on Reservations Make It Difficult to Move Recipients into Jobs

A letter report issued by the General Accounting Office with an abstract that begins "The 1996 Personal Responsibility and Work Opportunity Reconciliation Act gives Native American Indian tribes the option to administer Temporary Assistance for Needy Families (TANF) programs, either alone or as part of a consortium with other tribes, rather than receiving benefits and services from state TANF programs. Because of the difficult economic circumstances on many reservations, the law also gives tribal TANF programs more flexibility than it gives to states. Tribes have used various strategies to stimulate economic development, but despite these efforts, unemployment and poverty rates on reservations remain high and prospects for economic growth may be limited. To improve economic conditions on reservations, tribes operate enterprises in a range of commercial sectors. Nationally, the number of American Indian families receiving TANF assistance has declined in recent years; however, in some states, American Indians represent a large and increasing share of the state TANF caseload. To date, 174 tribes, either alone or as part of a consortium, are administering their own TANF programs and have used the flexibility in the act to tailor their tribal TANF programs to meet TANF requirements. However, many tribes have found …

Welfare Reform: With TANF Flexibility, States Vary in How They Implement Work Requirements and Time Limits (open access)

Welfare Reform: With TANF Flexibility, States Vary in How They Implement Work Requirements and Time Limits

A letter report issued by the General Accounting Office with an abstract that begins "Congress created the Temporary Assistance for Needy Families (TANF) block grant to replace the previous welfare program and help welfare recipients transition into employment. To this end, states are required to enforce work requirements, and face financial penalties if a minimum percentage of adults receiving cash assistance do not participate in work or work-related activities each year. This federal participation rate requirement has increased each year, reaching 50 percent for all families in fiscal year 2002, but it can be adjusted if caseload declines. In addition to work requirements, TANF places a 60 month lifetime limit on the amount of time families with adults can receive cash assistance. To receive TANF block grants, each state must also spend a specified amount of its own funds, referred to as state maintenance-of-effort (MOE) funds. The law allows states considerable flexibility to exclude families from work requirements and time limits. In addition, states may provide cash assistance to families and exempt them from work requirements and time limits by using state MOE in specified ways. States provided cash assistance funded by federal TANF or state MOE dollars to 2.1 …

Border Security: Investigators Transported Radioactive Sources Across Our Nation's Borders at Two Locations

Testimony issued by the Government Accountability Office with an abstract that begins "Given today's unprecedented terrorism threat environment and the resulting widespread congressional and public interest in the security of our nation's borders, GAO conducted an investigation testing whether radioactive sources could be smuggled across U.S. borders. Most travelers enter the United States through the nation's 154 land border ports of entry. Department of Homeland Security U.S. Customs and Border Protection (CBP) inspectors at ports of entry are responsible for the primary inspection of travelers to determine their admissibility into the United States and to enforce laws related to preventing the entry of contraband, such as drugs and weapons of mass destruction. GAO's testimony provides the results of undercover tests made by its investigators to determine whether monitors at U.S. ports of entry detect radioactive sources in vehicles attempting to enter the United States. GAO also provides observations regarding the procedures that CBP inspectors followed during its investigation. GAO has also issued a report on the results of this investigation (GAO-06-545R)."

Freight Railroad Regulation: Surface Transportation Board's Oversight Could Benefit From Evidence Better Identifying How Mergers Affect Rates (open access)

Freight Railroad Regulation: Surface Transportation Board's Oversight Could Benefit From Evidence Better Identifying How Mergers Affect Rates

A letter report issued by the General Accounting Office with an abstract that begins "Railroads have been a primary mode of freight transportation for many years, especially for bulk commodities such as coal and grain. Over the last 25 years, the freight railroad industry has undergone substantial consolidation largely to reduce costs and increase efficiency and competitiveness. Some companies that rely on rail shipments are concerned that the mergers have reduced railroad competition and led to higher rail rates and poorer service. This report reviews (1) the role the Surface Transportation Board plays in reviewing proposed railroad mergers and overseeing mergers that have been approved and how post-merger oversight is conducted, (2) how the Board mitigates potential harm to competition, and (3) how the Union Pacific/Southern Pacific merger affected rail rates in selected geographic areas. GAO found that the Board reviews railroad merger proposals and approves those that are consistent with the public interest, ensures that any potential merger-related harm to competition is mitigated to preserve competition, and oversees mergers that have been approved. The Board imposes conditions on mergers to mitigate potential harm to competition. The Board also focuses on the overall direction and magnitude of rate changes when …

Application of a New Method for Analyzing Images: Two-Dimensional Non-Linear Additive Decomposition (open access)

Application of a New Method for Analyzing Images: Two-Dimensional Non-Linear Additive Decomposition

This paper documents the application of a new image processing algorithm, two-dimensional non-linear additive decomposition (NLAD), which is used to identify regions in a digital image whose gray-scale (or color) intensity is different than the surrounding background. Standard image segmentation algorithms exist that allow users to segment images based on gray-scale intensity and/or shape. However, these processing techniques do not adequately account for the image noise and lighting variation that typically occurs across an image. NLAD is designed to separate image noise and background from artifacts thereby providing the ability to consistently evaluate images. The decomposition techniques used in this algorithm are based on the concepts of mathematical morphology. NLAD emulates the human capability of visually separating an image into different levels of resolution components, denoted as ''coarse'', ''fine'', and ''intermediate''. Very little resolution information overlaps any two of the component images. This method can easily determine and/or remove trends and noise from an image. NLAD has several additional advantages over conventional image processing algorithms, including no need for a transformation from one space to another, such as is done with Fourier transforms, and since only finite summations are required, the calculational effort is neither extensive nor complicated.

Measurement of the Spin of the Omega- Hyperon at Babar (open access)

Measurement of the Spin of the Omega- Hyperon at Babar

A measurement of the spin of the {Omega}{sup -} hyperon produced through the exclusive process {Xi}{sub c}{sup 0} {yields} {Omega}{sup -}K{sup +} is presented using a total integrated luminosity of 116 fb{sup -1} recorded with the BABAR detector at the e{sup +}e{sup -} asymmetric-energy B-Factory at SLAC. Under the assumption that the {Xi}{sub c}{sup 0} has spin 1/2, the angular distribution of the {Lambda} from {Omega}{sup -} {yields} {Lambda}K{sup -} decay is inconsistent with all half-integer {Omega}{sup -} spin values other than 3/2. Lower statistics data for the process {Omega}{sub c}{sup 0} {yields} {Omega}{sup -}{pi}{sup +} from a 230 fb{sup -1} sample are also found to be consistent with {Omega}{sup -} spin 3/2. If the {Xi}{sub c}{sup 0} spin were 3/2, an {Omega}{sup -} spin of 5/2 cannot be excluded.

FUNCTIONALIZED LATERAL SURFACE COATED LASERS FOR CHEM-BIO DETECTION (open access)

FUNCTIONALIZED LATERAL SURFACE COATED LASERS FOR CHEM-BIO DETECTION

We present a class of compact, monolithic, photonic sensors consisting of multiple section edge emitting lasers with functionalized lateral surface coatings for low level detection of chemical or biological agents. Specifically, we discuss 8 {micro}m x 250 {micro}m Pd-coated H{sub 2} sensors and configurations to reduce the minimum detection limit from 138ppm for passive sensors to 1ppm for active sensors. Compared with conventional optical H{sub 2} sensors that use fiber gratings, surface plasmon resonances, or surface reflectance, our sensors offer the advantages of smaller size, wider dynamic range, monolithic integration of laser source and detector, and 2-D scalability to arrays of sensors that are functionalized to detect different agents.

Resistive-Wall Instability in the Damping Rings of the ILC (open access)

Resistive-Wall Instability in the Damping Rings of the ILC

In the damping rings of the International Linear Collider (ILC), the resistive-wall instability is one of the dominant transverse instabilities. This instability directly influences the choice of material and aperture of the vacuum pipe, and the parameters of the transverse feedback system. This paper investigates the resistive-wall instabilities in an ILC damping ring under various conditions of beam pipe material, aperture, and fill pattern.

A 30 ps Timing Resolution for Single Photons with Multi-pixel Burle MCP-PMT (open access)

A 30 ps Timing Resolution for Single Photons with Multi-pixel Burle MCP-PMT

We have achieved {approx}30 psec single-photoelectron and {approx}12ps for multi-photoelectron timing resolution with a new 64 pixel Burle MCP-PMT with 10 micron microchannel holes. We have also demonstrated that this detector works in a magnetic field of 15kG, and achieved a single-photoelectron timing resolution of better than 60 psec. The study is relevant for a new focusing DIRC RICH detector for particle identification at future Colliders such as the super B-factory or ILC, and for future TOF techniques. This study shows that a highly pixilated MCP-PMT can deliver excellent timing resolution.

Development of an Optimum Tracer Set for Apportioning Emissions of Individual Power Plants Using Highly Time-Resolved Measurements and Advanced Receptor Modeling (open access)

Development of an Optimum Tracer Set for Apportioning Emissions of Individual Power Plants Using Highly Time-Resolved Measurements and Advanced Receptor Modeling

In previous studies, 11 elements (Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Se, and Zn) were determined in 30-minute aerosol samples collected with the University of Maryland Semicontinuous Elements in Aerosol Sampler (SEAS; Kidwell and Ondov, 2001, 2004; SEAS-II) in several locations in which air quality is influenced by emissions from coal- or oil-fired power plants. At this time resolution, plumes from stationary high temperature combustion sources are readily detected as large excursions in ambient concentrations of elements emitted by these sources (Pancras et al. ). Moreover, the time-series data contain intrinsic information on the lateral diffusion of the plume (e.g., {sigma}{sub y}), which Park et al. (2005 and 2006) have exploited in their Pseudo-Deterministic Receptor Model (PDRM), to calculate emission rates of SO{sub 2} and 11 elements (mentioned above) from four individual coal- and oil-fired power plants in the Tampa Bay area. In the current project, we proposed that the resolving power of source apportionment methods might be improved by expanding the set of maker species and that there exist some optimum set of marker species that could be used. The ultimate goal was to determine the utility of using additional elements to better identify and isolate …

Use of Optically Stimulated Luminescence Imaging Plates and Reader for Arms Control Applications (open access)

Use of Optically Stimulated Luminescence Imaging Plates and Reader for Arms Control Applications

Optically Stimulated Luminescence (OSL) technology has been pioneered at the Pacific Northwest National Laboratory (PNNL) for applications in personnel radiation dosimetry and commercially has become highly successful in replacing older technologies such as Thermoluminescence Dosimeters (TLDs) and film. OSL phosphors are used to measure radiation exposure by illuminating them with light after ionizing radiation exposure and measuring the amount of light emitted by the OSL phosphor. By using a two-dimensional plate of OSL material and raster scanning a light beam across the OSL plate a radiation pattern or image can be measured. The Arms Control community requires an electrons-free medium to measure the attributes of extent and symmetry on Pu pits in storage containers. OSL technology, used in the two-dimensional imaging mode, provides a means to measure these attributes with exposure times on the order of an hour. A special OSL reader has been built by PNNL to measure OSL imaging plates with a size of 20 cm by 30 cm. The reader uses 10 light emitting diode clusters with 10 corresponding photomultiplier tubes to measure an OSL imaging plate in less than 5 minutes. The resolution of each of the 10 measurement assemblies is 1 square-centimeter. A collimator assembly …
