A COMPARISON OF ECONOMIC IMPACT ESTIMATES FOR CHANGES IN THE FEDERAL GRAZING FEE: SECONDARY VS. PRIMARY DATA I/O MODELS

This paper compares estimates of local personal income impacts that could result from increases in the federal grazing fee, using secondary data input/output models (U.S. Forest Service IMPLAN) and five primary data input/output models. The results show that the impacts estimated by the IMPLAN models are usually higher than those estimate by primary data models.Livestock Production/Industries,

Teaching About Peace Through Children’s Literature

Historically children\u27s literature has always been used as a teaching tool with children, but today the choices of literature has grown and the audience expanded. Teaching moral messages was an underlying foundation for making books available for children. Early children\u27s books were often tied to religious teachings and folklore that had implied messages of staying close to home, listening to elders, caring for others over oneself, and traditional gender roles to name a few. Many adults have identified other subliminal messages as they critically analyzed some of the literature from the past. Some messages you will find are passive women needing to be rescued by a courageous prince (Rapunzel, Sleeping Beauty), distrust of stepmothers or strangers (Hansel & Gretel, Cinderella), and ethnic stereotyping (Five Chinese Brothers, Little Black Sambo). As a result, adults have become more critical of the literature selected for children. Educators are expected to be more aware of stereotypes touching on ethnicity, gender, social status, religion and cultural identity. At the same time we must ask how much is too much or not enough when it comes to cultural sensitivity or more specifically, social consciousness

Hydrogeology and recharge of the Split Rock Creek Aquifer, southeastern South Dakota

The rapid growth of the city of Sioux Falls, South Dakota, has created a great demand for additional sources of ground water. Due to limited information on the buried, confined Split Rock Creek aquifer near Sioux Falls, a detailed hydrogeologic assessment of the aquifer was conducted to determine the mechanism of recharge to the aquifer. A four-fold plan was earned out to gather the necessary data. . This plan involved determining the general hydrostratigraphy of the study area by reviewing available data and by drilling test holes where data were limited, collecting water-level data over an extended period, collecting water samples for major inorganic, radionuclide, and stable isotope analyses, and determining the hydraulic characteristics of the aquifer and confining layers through aquifer and baildown tests. Results indicate that the Split Rock Creek aquifer exists in paleo-valleys in the highly fractured Precambrian Sioux Quartzite. Aquifer materials are comprised of weathered and eroded Sioux Quartzite. The main portion of the aquifer lies to the east of Sioux Falls, between Brandon and Valley Springs, with aquifer thickness in this area exceeding 200 feet. Total dissolved solids in aquifer water collected from this area are less than 500 parts per million (ppm). Water levels in the aquifer increase during years of above normal precipitation, indicating recharge of the aquifer. Recharge has been great enough to sustain the approximately 292 million gallons of annual municipal pumping by Sioux Falls and Brandon. Water-chemistry data indicate post-depositional water present in the aquifer. Radiocarbon data indicate the age of the aquifer water ranges from approximately 3,000 to 10,000 years, and stable isotope data indicate the waters are meteoric in origin. Low permeability, unfractured till overlies the majority of the aquifer, eliminating the possibility of significant recharge in those areas. Ground-water flow directions indicate the main source of recharge is the Sioux Quartzite aquifer. Induced recharge from surficial outwash and alluviwn is possible in localized areas of river valleys

Improved Techniques for Heading Drivage

An obvious need exists for more efficient and safer techniques for driving development headings for longwalls and also, in many cases, for bord and pillar operations. A very expeditious solution to this problem is proposed, with the potential to drive such headings two or more times faster than can presently be achieved for any specific set of mining conditions

Reactivity of pi-complexes of Ti, V, and Nb towards dithioacetic acid: Synthesis and structure of novel metal sulfur-containing complexes

In order to use sulfur-containing resources economically and with minimal environmental damage, it is important to understand the desulfurization processes. Hydrodesulfurization, for example, is carried out on the surface of a heterogeneous metal sulfide catalyst. Studies of simple, soluble inorganic systems provide information regarding the structure and reactivity of sulfur-containing compounds with metal complexes. Further, consistent with recent trends in materials chemistry, many model compounds warrant further study as catalyst precursors. The reactivity of low-valent organometallic sandwich pi-complexes toward dithiocarboxylic acids is described. For example, treatment of bisbenzene vanadium with CH3CSSH affords a divanadium tetrakis(dithioacetate) complex. The crystallographically determined V-V bond distance, 2.800(2), is nearly the same as the V-V bond distance in a V(mu-nu squared-S2)2V' unit in the mineral patonite (VS4)n. The stability of the V2S4 core in the dimer is demonstrated by evidence of V2S4(+) in the mass spectrum (70 eV, solid probe) of the vanadium dimer. Several other systems relevant to HDS catalysis are also discussed

Observation of Feshbach resonances between two different atomic species

We have observed three Feshbach resonances in collisions between lithium-6 and sodium-23 atoms. The resonances were identified as narrow loss features when the magnetic field was varied. The molecular states causing these resonances have been identified, and additional lithium-sodium resonances are predicted. These resonances will allow the study of degenerate Bose-Fermi mixtures with adjustable interactions, and could be used to generate ultracold heteronuclear molecules
