No. 28:Changing Attitudes To Immigration And Refugee Policy In Botswana, Eugene Campbell, Johan Oucho

Southern African Migration Programme

For the last two decades, Botswana has had the reputation as a “country of immigration,” based on the large-scale import of skilled expatriates from Africa, Asia and the West. Successive census reports and immigration data, as well as previous SAMP surveys undertaken in the late 1990s, confirm the appropriateness of the designation. The SAMP surveys concentrated on three themes: (a) the attitudes and migration behaviour of skilled foreigners in the country; (b) the attitudes of Batswana towards cross-border migration to South Africa; and (c) the emigration potential of skilled Batswana. The surveys highlighted the tolerant and generally welcoming attitude prevailing …

Expression Of Spot In Borrelia Burgdorferi During Serum Starvation, Marc B. Concepcion, David R. Nelson

Cell and Molecular Biology Faculty Publications

Borrelia burgdorferi, the causative agent of Lyme disease, is transmitted by the tick Ixodes scapularis. A 2.9-kb fragment containing a putative spoT gene was isolated from B. burgdorferi genomic DNA by PCR amplification and cloned into a pBAD24 vector. The cloned gene complemented Escherichia coli mutant strain CF1693, which contains deletions of both the relA and spoT genes. The spoT gene in E. coli encodes a bifunctional enzyme capable of synthesizing and degrading (p)ppGpp, which mediates the stringent response during carbon source starvation. B. burgdorferi has been reported to have a stress response to serum starvation. Thin-layer chromatography …

Action Education In Land Use Decisions: Student Views On Urbanization And Farmland Loss, Mindi Schneider, Charles A. Francis, Dick Esseks

CARI Extension and Education Materials for Sustainable Agriculture

Loss of prime farmland is a serious concern in the United States and around the globe. With rapid urban population increases, the activities and perceived needs of concentrated groups of people result in the swallowing of some of the most fertile lands in this country. Today we have just under 2 acres of productive farmland per person in the United States. Given the current population growth rate due to births and immigration, plus the present rate of farmland loss, World Watch Institute estimates that we will have about 0.6 acres or one-third as much farmland available per person by 2055--a …

An Exact Solution For The Dispersive Alfven Switch-On Shock, Robert L. Hamilton, C C. Wu

Faculty Publications - Department of Mathematics

An exact solution for the dispersive Alfven switch-on shock is found in the case of weak nonlinearity, weak dispersion, and weak damping. Two singular and apparently nonphysical solutions are found as well. The switch-on shock solution is shown to reduce, in the appropriate limits, to two documented special cases of the shock: one case being a description of the planar shock without dispersion and the other being an asymptotic description of the circularly polarized wave standing upstream from the shock in the dispersive case. The solution developed here provides the complete shock structure for either case. This exact solution may …

A Preferred Vision For Administering Secondary Schools : A Reflective Essay, Gary D. Rippentrop

Graduate Research Papers

School leaders are put in a position of educating the community's most valuable asset, their children. School leaders must live their lives by the highest ethical standards to demonstrate to the community the importance of the district children's education.

A school leader needs to have a vision of what the school should exemplify in future years. Students should not only learn the academics, but should also learn to be good citizens. To be good citizens, the students of today must have knowledge of where our country has been in the past to better understand what we stand for today. To …

Transformation Of 2-Line Ferrihydrite To 6-Line Ferrihydrite Under Oxic And Anoxic Conditions, Ravi K. Kukkadapu, John M. Zachara, James K. Fredrickson, Steven C. Smith, Alice C. Dohnalkova, Colleen K. Russel

United States Department of Energy: Publications

Mineralogical transformations of 2-line ferrihydrite were studied under oxic and Fe³⁺-reducing conditions to establish the role, if any, of 6-line ferrihydrite (“well” organized ferrihydrite) in the reaction pathway and as a final product. In oxic experiments, concentrated suspensions (0.42 mol/L Fe³⁺ in 0.1 mol/L NaClO₄) of freshly synthesized 2-line ferrihydrite, with and without 3% Ni2+, were aged at an initial pH = 7.2 (unbuffered and unadjusted) and 25°C for more than three years. X-ray diffraction, transmission electron microscopy, and Mössbauer spectroscopy measurements were performed on the solids after different aging periods. The primary mineralogical products …

Microbial Reduction Of Structural Fe(Iii) In Illite And Goethite, Hailiang Dong, Ravi K. Kukkadapu, James K. Fredrickson, John M. Zachara, David W. Kennedy, Heather M. Kostandarithes

United States Department of Energy: Publications

Microbial reduction of Fe(III) in illite was studied to evaluate the possibility of microbial utilization of Fe(III) in sedimentary clays and to determine the effects of bioreduction on clay composition and structure. A subsurface bacterium (Shewanella putrefaciens CN32) and illite separates (

Mossbauer And Optical Spectroscopic Study Of Temperature And Redox Effects On Iron Local Environments In A Fe-Doped (0.5 Mol% Fe2o3)18na2o–72sio2 Glass, Ravi K. Kukkadapu, Hong Li, Gary L. Smith, J.D. Crum, Jun-Sik Jeoung, W. Howard Poisl, Michael C. Weinberg

United States Department of Energy: Publications

Local environments of ferric and ferrous irons were systematically studied with Mössbauer (at liquid helium temperature)and ultraviolet–visible–near infrared spectroscopic methods for various 18Na₂O–72SiO₂ glasses doped with 0.5 mol% Fe₂O₃. These were prepared at temperatures of 1300–1600 °C in ambient air or at 1500 °C under reducing conditions with oxygen partial pressures from 12.3 to 0.27 x 10^-7 atmospheres. The Mössbauer spectroscopic method identified three types of local environments, which were represented by the Fe³⁺ sextet, the Fe³⁺ doublet, and the Fe²⁺ doublet. The Fe³⁺ sextet ions were assigned …

Influence Of Electron Donor/Acceptor Concentrations On Hydrous Ferric Oxide (Hfo) Bioreduction, James K. Fredrickson, Sreenivas Kota, Ravi K. Kukkadapu, Chongxuan Liu, John M. Zachara

United States Department of Energy: Publications

Dissimilatory metal-reducing bacteria (DMRB) facilitate the reduction of Fe and Mn oxides in anoxic soils and sediments and play an important role in the cycling of these metals and other elements such as carbon in aqueous environments. Previous studies investigating the reduction of Fe(III) oxides by DMRB focused on reactions under constant initial electron donor (lactate) and electron acceptor (Fe oxide) concentrations. Because the concentrations of these reactants can vary greatly in the environment and would be expected to influence the rate and extent of oxide reduction, the influence of variable electron acceptor and donor concentrations on hydrous ferric oxide …

Nonlocal Bacterial Electron Transfer To Hematite Surfaces, Kevin Rosso, John M. Zachara, James K. Fredrickson, Yuri Gorby, Steven Smith

United States Department of Energy: Publications

Mechanisms by which dissimilatory iron-reducing bacteria utilize iron and manganese oxide minerals as terminal electron acceptors for respiration are poorly understood. In the absence of exogenous electron shuttle compounds, extracellular electron transfer is generally thought to occur through the interfacial contact area between mineral surfaces and attached cells. Possible alternative reduction pathways have been proposed based on the discovery of a link between an excreted quinone and dissimilatory reduction. In this study, we utilize a novel experimental approach to demonstrate that Shewanella putrefaciens reduces the surface of crystalline iron oxides at spatial locations that are distinct from points of attachment.

Transport Of Multiple Tracers In Variably Saturated Humid Region Structured Soils And Semi-Arid Region Laminated Sediments, M.A. Mayes, P.M. Jardine, T.L. Mehlhorn, B.N. Bjornstad, J.L. Ladd, John M. Zachara

United States Department of Energy: Publications

The processes governing physical nonequilibrium (PNE)—coupled preferential flow and matrix diffusion—are diverse between humid and semi-arid regions, and are directly related to climate and rock/sediment type, and indirectly related to subsequent soil profile development. The fate and transport of contaminants in these variably saturated undisturbed media is largely a function of the influence of PNE processes. Large cores of laminated silts and sands were collected from the US Department of Energy Pacific Northwest National Laboratory (PNNL) in semi-arid south central Washington. Additional cores of weathered, fractured interbedded limestone and shale saprolite were collected from the Oak Ridge National Laboratory (ORNL) …

The Distribution Of Chlorpyrifos Following A Crack And Crevice Type Application In The Us Epa Indoor Air Quality Research House, D. M. Stout Ii, M. A. Mason

United States Environmental Protection Agency: Publications

A study was conducted in the US EPA Indoor Air Quality (IAQ) Research House to determine the spatial and temporal distribution of chlorpyrifos following a professional crack and crevice application in the kitchen. Following the application, measurements were made in the kitchen, den and master bedroom over 21 days. Airborne concentrations were collected using both polyurethane foam (PUF) and the OSHA versatile sampler composed of XAD and PUF media located in tandem. Measured airborne concentrations were similar for the two samplers and were higher in the three rooms following the application. The highest measured concentrations were reached during the initial …

Geologic Studies Of Mercury By The U.S. Geological Survey

United States Geological Survey: Publications

A liquid at room temperature, mercury is a unique metal with unusual properties. Elemental mercury has long been used in thermometers because it responds to changes in temperature. In fact, mercury’s many diverse properties have made it useful for many products. Mercury is a good metallic conductor with a low electrical resistivity; it has been used in electrical products including electrical wiring and switches, fluorescent lamps, mercury batteries, and thermostats (Eisler, 1987). Mercury also is used in navigational instruments to measure changes in temperature and pressure. In the medical field, mercury is used as a component in dental fillings and …

Evidence For Disease-Related Amphibian Decline In Colorado, Erin Muths, Paul Stephen Corn, Allan P. Pessier, D. Earl Green

United States Geological Survey: Staff Publications

The recent discovery of a pathogenic fungus (Batrachochytrium dendrobatidis) associated with declines of frogs in the American and Australian tropics, suggests that at least the proximate cause, may be known for many previously unexplained amphibian declines. We have monitored boreal toads in Colorado since 1991 at four sites using capture–recapture of adults and counts of egg masses to examine the dynamics of this metapopulation. Numbers of male toads declined in 1996 and 1999 with annual survival rate averaging 78% from 1991 to 1994, 45% in 1995 and 3% between 1998 and 1999. Numbers of egg masses also declined. …

A Longitudinal Assessment Of The Aquatic Macroinvertebrate Community In The Channelized Lower Missouri River, Barry C. Poulton, Mark L. Wildhaber, Collette S. Charbonneau, James F. Fairchild, Brad G. Mueller, Christopher J. Schmitt

United States Geological Survey: Staff Publications

We conducted an aquatic macroinvertebrate assessment in the channelized reach of the lower Missouri River, and used statistical analysis of individual metrics and multimetric scores to identify community response patterns and evaluate relative biological condition. We examined longitudinal site differences that are potentially associated with water quality related factors originating from the Kansas City metropolitan area, using data from coarse rock substrate in flowing water habitats (outside river bends), and depositional mud substrate in slack water habitats (dike fields). Three sites above river mile (RM) 369 in Kansas City (Nebraska City, RM = 560; St. Joseph, RM = 530; Parkville, …

Interplay Of Late Cenozoic Siliciclastic Supply And Carbonate Response On The Southeast Florida Platform, Kevin J. Cunningham, Stanley D. Locker, Albert C. Hine, David Bukry, Laura A. Guertin, John A. Barron

United States Geological Survey: Staff Publications

High-resolution seismic-reflection data collected along the length of the Caloosahatchee River in southwestern Florida have been correlated to nannofossil biostratigraphy and strontium-isotope chemostratigraphy at six continuously cored boreholes. These data are interpreted to show a major Late Miocene(?) to Early Pliocene fluvial– deltaic depositional system that prograded southward across the carbonate Florida Platform, interrupting nearly continuous carbonate deposition since early in the Cretaceous. Connection of the platform top to a continental source of siliciclastics and significant paleotopography combined to focus accumulation of an immense supply of siliciclastics on the southeastern part of the Florida Platform. The remarkably thick (> 100 …

How The Supreme Court Decides To Review Intellectual Property Cases, 3 J. Marshall Rev. Intell. Prop. L. 19 (2003), Matthew M. Neumeier

UIC Review of Intellectual Property Law

Because Supreme Court review is essentially discretionary, it is increasingly rare for the Court to hear an argument concerning Intellectual Property rights. However the Supreme Court will critically review cases that belong in one of four distinct categories. These include cases in which: (1) lower court decisions conflict, (2) lower courts have departed from accepted and usual court proceedings, (3) an important federal question is decided, and (4) lower courts have departed from Supreme Court precedent. This article provides practitioners with some guidance in determining whether the Supreme Court is likely to review a lower court decision on an Intellectual …
