Seeing The Students Behind The Stereotypes: The Perspective Of Three Preservice Teachers, Alison Cook-Sather, Ondrea Reisinger Dec 2000

Seeing The Students Behind The Stereotypes: The Perspective Of Three Preservice Teachers, Alison Cook-Sather, Ondrea Reisinger

Education Program Faculty Research and Scholarship

Stereotypes are a particularly insidious factor in the formation of pre‐ and in‐service teachers’ images of students. Teachers who rely on stereotypes rather than try to see the students behind them run the risk of letting cultural and individual biases work to their own disadvantage and to the disadvantage of the next generation of high school students. This article describes a project called Teaching and Learning Together that brings preservice teachers into direct dialogue with high school students with the goal of helping preservice teachers learn to attend to high school students and analyze the pedagogical implications of that attention …

Earning Patterns Of Mexican Workers In The Southern Region: A Focus On Nonmetro/Metro Distinctions, Rogelio Saenz Dec 2000

Earning Patterns Of Mexican Workers In The Southern Region: A Focus On Nonmetro/Metro Distinctions, Rogelio Saenz

Journal of Rural Social Sciences

The last few years have witnessed a tremendous change in the geographic location patterns of the Mexican population in the United States. The rural South represents one of the areas that have seen a noticeable growth in the Mexican population over the last few years. Unfortunately, data necessary to examine the social and economic adjustment of Mexicans in this area are not available at this time. This analysis uses data from the 1990 Public Use Microdata Sample (PUMS) to examine the earnings patterns bf Mexican-origin workers in the South. The sample used to conduct the analysis includes 9,509 Mexican-origin workers …

Heavy Metals And Organic Pollutants In Sediments Of Dar Es Salaam Harbour Prior To Dredging In 1999, J F Machiwa Dec 2000

Heavy Metals And Organic Pollutants In Sediments Of Dar Es Salaam Harbour Prior To Dredging In 1999, J F Machiwa

Tanzania Journal of Science

Heavy metals and organic contaminants were analysed in the sediments of the inner area of the Dar es Salaam harbour. Complementary analytical parameters, such as, the organic carbon content and the silt/clay fraction of the sediments showed good positive correlation (r = 0.64). Stations that had high content of fine grain material in the sediment also indicated relatively high level of organic carbon and pollutants. The Florida criteria (MacDonald 1993) for assessment of pollution of tropical marine sediments was adopted in oredr to evaluate the extent of pollution in Dar es Salaam harbour sediments. The Florida criteria is one of …

Composition And Anaerobic Digestion Of Single And Combined Organic Fractions Of Municipal Solid Waste Of Dar Es Salaam, A K Kivaisi, J Mukisa Dec 2000

Composition And Anaerobic Digestion Of Single And Combined Organic Fractions Of Municipal Solid Waste Of Dar Es Salaam, A K Kivaisi, J Mukisa

Tanzania Journal of Science

The composition of major categories of municipal solid waste (MSW) of Dar es salaam city was determined. Food remains and vegetable matter constituted 80-90% of the categories. Organic fractions of the individual categories contained 18-20 % total solid (TS), 30-50 % (dry weight) total fibre and 1-1.3 % nitrogen. The assorted organic fractions were tested for anaerobic conversion into biogas at 55°C in batch cultures for 14 days with a mixed population of microorganisms. At a substrate concentration of 6-8 g volatile solids per litre fermenter volume (g VS l-1 FV) individual fractions were degraded by 51-75% and gave methane …

Subsidence History Of The Rukwa Rift In South West Tanzania Analysed From Ivuna Well, E I Mbede Dec 2000

Subsidence History Of The Rukwa Rift In South West Tanzania Analysed From Ivuna Well, E I Mbede

Tanzania Journal of Science

The variation in subsidence rate during rift basin development is a good indication for the Geodynamic history of a sedimentary basin. The sedimentary section of Ivuna Well is herein used to explain the structural evolution of Rukwa Basin within the Western Rift of the East African Rift System. The sedimentary record of Ivuna Well is extracted from published information. The effects of sedimentary load, corrected for compaction and variation in water depth, and lake-level have been removed to obtain the "tectonic subsidence." Curves show two phases of accelerated subsidence related to the fault controlled rifting phases: The Karoo rifting and …

Thermogravimetric Study Of Gadolinium Chlorotungstate In Air Between 25 And 1500°C., F N Ngassapa, N U Venskovskii Dec 2000

Thermogravimetric Study Of Gadolinium Chlorotungstate In Air Between 25 And 1500°C., F N Ngassapa, N U Venskovskii

Tanzania Journal of Science

Using DTA, X-ray powder diffraction, chemical and optical methods, the thermostability of Gd3WO6Cl3 was investigated. The compound was relatively stable on heating in air up to 710oC. Above this temperature it exhibited two decomposition temperature ranges (710-900oC and 900-1130oC). The final product consisted of a mixture of gadolinium tungstate of different composition. This suggests the decomposition scheme of polyphase products

Preliminary Evidence For A Second -525-545 Ma Old Event Of Granilate Facies Metamorphism In The Mozambique Belt Of Tanzania And Its Implication For A Two-Stage Model For Gondwana Assembly, M A H Maboko Dec 2000

Preliminary Evidence For A Second -525-545 Ma Old Event Of Granilate Facies Metamorphism In The Mozambique Belt Of Tanzania And Its Implication For A Two-Stage Model For Gondwana Assembly, M A H Maboko

Tanzania Journal of Science

Garnets from two samples of the Kitumbi granulites in the Mozambique Belt of north eastern Tanzania yield Sm-Nd ages of 525±15 Ma and 545±15 Ma. At the 95% confidence level, these ages are younger than the 576 ±15 to 634±16 Ma (Mean 606±12 Ma) ages previously reported from the more extensive Eastern Granulites. The Kitumbi garnets are therefore interpreted as dating cooling from a granulite facies event that is distinctly younger than the 630-700 Ma event that produced the Eastern Granulites. Unlike the Eastern Granulites, the Kitumbi rocks occur as small enclaves not separated from the surrounding amphibolite facies gneisses …

Influence Of Endocrine Activity On Larval Development In Busseola Fusca (Fuller) (Lepidoptera:Noctudine), M Njau Dec 2000

Influence Of Endocrine Activity On Larval Development In Busseola Fusca (Fuller) (Lepidoptera:Noctudine), M Njau

Tanzania Journal of Science

The present study investigated the role of juvenile and moulting hormones in development of Busseola fusca. Morphometric measurements were used to distinguish differences in endocrine activity between non-diapause and diapause development with regard to the prothoracic glands and the corpora allata. The corpora allata of non-diapause larvae were similar in size to those of diapause larvae. The critical period for the prothoracic glands to produce the required titer of ecdysone for further development was by the third day after ecdysis to the last larval instar. Juvenile hormone extracts from haemolymph of Busseola fusca larvae in non-diapause and diapause development had …

Ramanujan-Like Congreuences Of The Distinct Partition Function, Ian Blumenfeld, Christi Carlstead, Mimi Cukier, Wesley Terway Dec 2000

Ramanujan-Like Congreuences Of The Distinct Partition Function, Ian Blumenfeld, Christi Carlstead, Mimi Cukier, Wesley Terway

Mathematical Sciences Technical Reports (MSTR)

In his work with the partition function, Ramanujan observed several congruences of the form p(An + B) = 0 (mod m). We adapt this form to several congruences of the distinct partition function, p2(n). We show that one can determine all ordered pairs of integers (A;B) for which p2(An + B)=0 (mod 2) and show families of congruences modulo 4. Finally, we offer a proof of a congruence modulo 5 satisfied by the distinct partition function.

Optimal Solvability For The Dirichlet And Neumann Problem In Dimension Two, Atanas Stefanov, Gregory C. Verchota Dec 2000

Optimal Solvability For The Dirichlet And Neumann Problem In Dimension Two, Atanas Stefanov, Gregory C. Verchota

Mathematics - All Scholarship

We show existence and uniqueness for the solutions of the regularity and the Neumann problems for harmonic functions on Lipschitz domains with data in the Hardy spaces Hp1,(partial D)(Hp (partial D)), p>2/3-E, where D C R2 and E is a (small) number depending on the Lipschitz nature of D. This in turn implies that solutions to the Dirichlet problem with data in the Holder class C1/2+E(partial D) are themselves in C1/2+E(D). Both of these results are sharp. In fact, we prove a more general statement regarding the Hp solvability …

The Electrostatic Interaction Of Charged, Dust-Particle Pairs In Plasmas, M. E. Markes, P. F. Williams Dec 2000

The Electrostatic Interaction Of Charged, Dust-Particle Pairs In Plasmas, M. E. Markes, P. F. Williams

Department of Electrical and Computer Engineering: Faculty Publications

We report the results of a study of the electrostatic interaction between negatively charged particles in a plasma. The goal of the study was to investigate the possibility of an attractive interaction which would make possible the formation of “molecules” of particles. For all approximations relating the positive ion density to the local electrostatic potential that we examined, we find that the interaction is repulsive for all particle separations.

Upper White River Bmp Implementation Project (Nps Final Report), Paul F. Vendrell, K. F. Steele, M. A. Nelson, R. W. Mcnew Dec 2000

Upper White River Bmp Implementation Project (Nps Final Report), Paul F. Vendrell, K. F. Steele, M. A. Nelson, R. W. Mcnew

Arkansas Water Resources Center Technical Reports

The project objective was to monitor agricultural best management practices implemented to minimize sediment, nutrient, and bacterial impact on water quality of the Upper White River watershed. The project targeted the primary agricultural causes of non-point source nutrient and bacterial pollution in three sub-basins of the White River in the Beaver Lake Watershed. Areas with high animal densities targeted high source areas. High source areas were treated with best management practices (BMP) in an effort to reduce the impact to the White River and Beaver Lake. The predominant BMP implemented was waste management, a component of the farm nutrient management …

Nonlinear Effects Of Physisorption On Static Friction, G.T. Gao, Xiao Cheng Zeng, Dennis J. Diestler Dec 2000

Nonlinear Effects Of Physisorption On Static Friction, G.T. Gao, Xiao Cheng Zeng, Dennis J. Diestler

Xiao Cheng Zeng Publications

The effects of a physisorbed film on the force of static friction in a model contact (monatomic adsorbate confined between plane-parallel walls) were investigated by Monte Carlo simulation. At fixed coverage the friction curve (shear yield stress vs normal stress) exhibits a marked nonlinearity, which results from a competition between adsorbate–wall interactions that predominate at low loads and wall–wall interactions that set in beyond a threshold load, which increases with coverage. Previous proximal-probe and computer experiments, carried out at high coverages, see only the initial (low-load) linear portion of the friction curve.

Comparing A Hyperspectral Monte-Carlo Approach For Simulating Water Surface Reflectance Signatures Based Upon Radiative Transfer Theory: Simulating Clear Water & Caribbean Sea Bottom Types, Charles R. Bostater Jr., Manuel Gimond, Matthew Campbell Dec 2000

Comparing A Hyperspectral Monte-Carlo Approach For Simulating Water Surface Reflectance Signatures Based Upon Radiative Transfer Theory: Simulating Clear Water & Caribbean Sea Bottom Types, Charles R. Bostater Jr., Manuel Gimond, Matthew Campbell

Ocean Engineering and Marine Sciences Faculty Publications

A homogeneous water column hyperspectral Monte Carlo modeling approach is compared to an analytical solution to a radiative transfer model system for irradiance. Both mathematical models and the solution approaches describe the transfer of irradiant light in a homogeneous medium. The analytical model has been previously used to describe the transfer of irradiant energy in a homogenous water column, with and without fluorescence source terms as well as a direct specular or a collimated irradiance source term. The response of the water surface reflectance under solar irradiance or an artificial collimated light source is thus modeled. Synthetic reflectance signatures generated …

Numerical Simulation Of The Marine Atmospheric Boundary Layer Flow Over The Cape Canaveral Region And Gulf Stream Using Avhrr Sst – An Atmospheric Seabreeze Model, Charles R. Bostater, Manuel Gimond, Erik Uhlhorn, Ted Mcnally Dec 2000

Numerical Simulation Of The Marine Atmospheric Boundary Layer Flow Over The Cape Canaveral Region And Gulf Stream Using Avhrr Sst – An Atmospheric Seabreeze Model, Charles R. Bostater, Manuel Gimond, Erik Uhlhorn, Ted Mcnally

Ocean Engineering and Marine Sciences Faculty Publications

An atmospheric mesoscale numerical model has been developed and applied to the marine atmospheric boundary layer (MABL) in the vicinity of sharp sea-surface temperature (SST) gradients. The Gulf Stream offshore ofEast Central Florida near Cape Canaveral is the region of interest. The model equations which govern atmospheric behavior are based on the basic conservation laws ofmass, momentum, and energy. A "primitive" equation formulation is used to produce preliminary predictions ofhorizontal velocity, potential temperature, and water vapor. The hydrostatic approximation is applied to the vertical momentum conservation equation and the anelastic form ofthe continuity equation is used to approximate mass conservation. …
