The Rural Educator

This article highlights the significance of using ecojustice theory in scholarly discussions regarding issues of science teaching and learning in rural communities of the Southeastern United States. We offer an explanation of how ecojusticetheory provides a new way to look at often studied issues surrounding education in rural communities. This article specifically addresses the issue of science teacher recruitment and retention and draws attention to some of the emergingtensions faced by educators in the Black Belt region of Georgia.

Creating Highly Qualified Teachers, Dawn L. Mollenkopf

The Rural Educator

The “highly qualified teacher” requirement of No Child Left Behind has put pressure on rural school districts to recruit and retain highly qualified regular and special education teachers. If necessary, they may utilize uncertified, rural teachers with provisional certification; however, these teachers may find completing the necessary certification difficult due to time, distance, and geographic barriers. The University of Nebraska at Kearney has been able to address this need by: (1) creating access to the university’s certification program, (2) providing professional supports, (3) tailoring assignments, projects, and field based practicum experiences and (4) building capacity for rural teachers who have …

Inhibitors Of Bacterial N-Succinyl-L,L-Diaminopimelic Acid Desuccinylase (Dape) And Demonstration Of In Vitro Antimicrobial Activity, Danuta Gillner, Nicola Armoush, Richard C. Holz, Daniel P. Becker

Chemistry: Faculty Publications and Other Works

The dapE-encoded N-succinyl-l,l-diaminopimelic acid desuccinylase (DapE) is a critical bacterial enzyme for the construction of the bacterial cell wall. A screen biased toward compounds containing zinc-binding groups (ZBG’s) including thiols, carboxylic acids, boronic acids, phosphonates and hydroxamates has delivered a number of micromolar inhibitors of DapE from Haemophilus influenzae, including the low micromolar inhibitor l-captopril (IC50 = 3.3 μM, Ki = 1.8 μM). In vitro antimicrobial activity was demonstrated for l-captopril against Escherichia coli.

Homological Dimensions And Regular Rings, Alina Iacob, Srikanth B. Iyengar

Mathematical Sciences: Faculty Publications

A question of Avramov and Foxby concerning injective dimension of complexes is settled in the affirmative for the class of noetherian rings. A key step in the proof is to recast the problem on hand into one about the homotopy category of complexes of injective modules. Analogous results for flat dimension and projective dimension are also established.

The goal of this second step in the process is to evaluate the current curriculum against state standards so teachers …

The Role Of Engineering Graphics In The Civil Engineering Technology Curriculum, Charles F. Didomenico

Regis University Student Publications (comprehensive collection)

This author presents the concept that the basic mechanical drawing course at Pueblo Community College is no longer relevant to the graphics skills required in industry and should not be a prerequisite in the civil engineering technology curriculum. A review of literature reveals that basic mechanical drawing courses are not routinely integrated into civil engineering technology programs in the Colorado Community College System. The literature shows that the majority of programs in the community college system utilize computer aided drafting as the prerequisite. Alternatively, as a replacement, the author presents a hybrid mechanical drawing-computer aided drafting (CAD) curriculum that integrates …

Non-Commutative Desingularization Of Determinantal Varieties, I, Ragnar-Olaf Buchweitz, Graham J. Leuschke, Michel Van Den Bergh

Mathematics - All Scholarship

We show that determinantal varieties defined by maximal minors of a generic matrix have a non-commutative desingularization, in that we construct a maximal Cohen-Macaulay module over such a variety whose endomorphism ring is Cohen-Macaulay and has finite global dimension. In the case of the determinant of a square matrix, this gives a non-commutative crepant resolution.

Two-Stage Decompositions For The Analysis Of Functional Connectivity For Fmri With Application To Alzheimer's Disease Risk, Brian S. Caffo, Ciprian M. Crainiceanu, Guillermo Verduzco, Stewart H. Mostofsky, Susan Spear-Bassett, James J. Pekar

COBRA Preprint Series

Functional connectivity is the study of correlations in measured neurophysiological signals. Altered functional connectivity has been shown to be associated with numerous diseases including Alzheimer's disease and mild cognitive impairment. In this manuscript we use a two-stage application of the singular value decomposition to obtain data driven population-level measures of functional connectivity in functional magnetic resonance imaging (fMRI). The method is computationally simple and amenable to high dimensional fMRI data with large numbers of subjects. Simulation studies suggest the ability of the decomposition methods to recover population brain networks and their associated loadings. We further demonstrate the utility of these …

The Thermodynamic And Ground State Properties Of The Tip4p Water Octamer, E. Asare, A-R. Musah, E. Curotto, David L. Freeman, J. D. Doll

Chemistry Faculty Publications

Several stochastic simulations of the TIP4P [W. L. Jorgensen, J. Chandrasekhar, J. D. Madura, R. W. Impey, and M. L. Klein, J. Chem. Phys. 79, 926 (1983)] water octamer are performed. Use is made of the stereographic projection path integral and the Green’s function stereographic projection diffusion Monte Carlo techniques, recently developed in one of our groups. The importance sampling for the diffusion Monte Carlo algorithm is obtained by optimizing a simple wave function using variational Monte Carlo enhanced with parallel tempering to overcome quasiergodicity problems. The quantum heat capacity of the TIP4P octamer contains a pronounced melting peak …

Multiplicity In Algebra And Geometry, Florian Enescu

Colloquium

The multiplicity of a root of a polynomial equals its order of vanishing. A point on an algebraic variety is a solution to a system of polynomial equations. For such a point, how is its multiplicity defined? We will discuss some of the historical approaches to this question. In relation to this, we will present a new multiplicity, called Hilbert-Kunz multiplicity, and discuss some open problems related to it that have algebraic-geometric as well as number-theoretical flavor.

Parameter Estimation For The Lognormal Distribution, Brenda Faith Ginos

Theses and Dissertations

The lognormal distribution is useful in modeling continuous random variables which are greater than or equal to zero. Example scenarios in which the lognormal distribution is used include, among many others: in medicine, latent periods of infectious diseases; in environmental science, the distribution of particles, chemicals, and organisms in the environment; in linguistics, the number of letters per word and the number of words per sentence; and in economics, age of marriage, farm size, and income. The lognormal distribution is also useful in modeling data which would be considered normally distributed except for the fact that it may be more …

Enhanced Vehicle Identification Utilizing Sensor Fusion And Statistical Algorithms, Stephane Roussel, Hemanth Porumamilla, Charles Birdsong, Peter Schuster, Christopher Clark

Mechanical Engineering

Several studies in the area of vehicle detection and identification involve the use of probabilistic analysis and sensor fusion. While several sensors utilized for identifying vehicle presence and proximity have been researched, their effectiveness in identifying vehicle types has remained inadequate. This study presents the utilization of an ultrasonic sensor coupled with a magnetic sensor and the development of statistical algorithms to overcome this limitation. Mathematical models of both the ultrasonic and magnetic sensors were constructed to first understand the intrinsic characteristics of the individual sensors and also to provide a means of simulating the performance of the combined sensor …

Interactions Between Connected Half-Sarcomeres Produce Emergent Mechanical Behavior In A Mathematical Model Of Muscle, Kenneth S. Campbell

Physiology Faculty Publications

Most reductionist theories of muscle attribute a fiber's mechanical properties to the scaled behavior of a single half-sarcomere. Mathematical models of this type can explain many of the known mechanical properties of muscle but have to incorporate a passive mechanical component that becomes approximately 300% stiffer in activating conditions to reproduce the force response elicited by stretching a fast mammalian muscle fiber. The available experimental data suggests that titin filaments, which are the mostly likely source of the passive component, become at most approximately 30% stiffer in saturating Ca2+ solutions. The work described in this manuscript used computer modeling to …

Part 2: Professional Development Curriculum: Integrating Molecular Biology And Microbiology Into The Existing Secondary Biology Curricula, Mary Ruth Greer

Theses and Dissertations

PART 1: Thirty-one medicinal plant species from Hawaii, Morocco, and the Sonoran Desert, USA have been shown in past studies to be highly inhibitory to pathogenic bacteria, fungi, and certain cancer cell lines. However, none were tested for antiviral activity. Acetone and methanol extracts from these species were bio-assayed for antiviral activity against herpes simplex virus types 1 and 2 (HSV 1 and HSV 2) and for cytotoxicity to the Vero C1008 cell line. Extracts from these species were tested in vitro for antiviral activity using an immunoperoxidase mini-plaque reduction assay to detect viral structural protein synthesis. Sulforhodamine B and …

Revitalization And Modernization Of Old Havana, Cuba, Mileydis Hernandez

USF Tampa Graduate Theses and Dissertations

Architecture around the world has been very influential for determining the historical background of many cities. The architecture of the city of Havana in Cuba is etched with unique historical forces and signature buildings. This architecture embodies local reproductions of Western and European styles. The superimposing of Western and European styles led to the formation of a "strange baroquism" that defined the "lasting features of the overall idiosyncrasy of the city."

Since Cuba's change of government in the 1950s, architecture has progressed very little. From the day Castro took power, Havana's skyline has hardly altered. After the fall of the …
