Differentiating Information Skills And Computer Skills: A Factor Analytic Approach, Judith M. Pask, E. Stewart Saunders
Libraries Research Publications
A basic tenet of information literacy programs is that the skills needed to use computers and the skills needed to find and evaluate information are two separate sets of skills. Outside the library this is not always the view. The claim is sometimes made that information skills are acquired by learning computer skills. All that is needed is a computer lab and someone to teach computer skills. This study uses data from a survey of computer and information skills to determine whether or not these skills are separate entities. The survey was given to incoming freshmen at Purdue University in …

Fast Algorithms For Fragment Based Completion In Images Of Natural Scenes, Siddharth Rajkumar Borikar
Electronic Theses and Dissertations
Textures are used widely in computer graphics to represent fine visual details and produce realistic looking images. Often it is necessary to remove some foreground object from the scene. Removal of the portion creates one or more holes in the texture image. These holes need to be filled to complete the image. Various methods like clone brush strokes and compositing processes are used to carry out this completion. User skill is required in such methods. Texture synthesis can also be used to complete regions where the texture is stationary or structured. Reconstructing methods can be used to fill in large-scale …
Teacher Performance Pay: The Perceptions Of Certified School-Based Pe, Gregory Adkins
Teacher Performance Pay: The Perceptions Of Certified School-Based Pe, Gregory Adkins
Electronic Theses and Dissertations
To meet the continued demand for educational reform, the state of Florida enacted legislation in 1998 that required school boards to base a portion of the salary for school administrators and instructional personnel on performance. Although ahead of the required statutory timeline, the School District of Lee County implemented a teacher performance pay plan during the 19981999 school year as a result of Florida's legislative direction. The problem of this study was to determine the perceptions of Southwest Florida school-based certified staff regarding the implementation of teacher performance pay in a school district where performance pay had been in operation …

'A Man's World'?: A Study Of Female Workers At Nasa's Kennedy Space C, Nanci Schwartz
Electronic Theses and Dissertations
By focusing on women workers at NASA's Kennedy Space Center in Florida, this study seeks to understand why women were initially congregated in certain occupations such as clerical work and later moved into non-traditional jobs such as engineering and the sciences. Such an investigation requires careful examination of the changing attitudes towards female workers in technical or non-traditional fields and why and how those attitudes changed over time and the extent to which this occurred. It also attempts to identify areas of continuing concern. The study reveals that several factors contributed to the women's progress in the workplace. These included …
Monolithic Integration Of Dual Optical Elements On High Power Semicond, Laurent Vaissie
Monolithic Integration Of Dual Optical Elements On High Power Semicond, Laurent Vaissie
Electronic Theses and Dissertations
This dissertation investigates the monolithic integration of dual optical elements on high power semiconductor lasers for emission around 980nm wavelength. In the proposed configuration, light is coupled out of the AlGaAs/GaAs waveguide by a low reflectivity grating coupler towards the substrate where a second monolithic optical element is integrated to improve the device performance or functionality. A fabrication process based on electron beam lithography and plasma etching was developed to control the grating coupler duty cycle and shape. The near-field intensity profile outcoupled by the grating is modeled using a combination of finite-difference time domain (FDTD) analysis of the nonuniform …
Data Transmission Scheduling For Distributed Simulation Using Packet A, Juan Vargas-Morales
Data Transmission Scheduling For Distributed Simulation Using Packet A, Juan Vargas-Morales
Electronic Theses and Dissertations
Communication bandwidth and latency reduction techniques are developed for Distributed Interactive Simulation (DIS) protocols. Using logs from vignettes simulated by the OneSAF Testbed Baseline (OTB), a discrete event simulator based on the OMNeT++ modeling environment is developed to analyze the Protocol Data Unit (PDU) traffic over a wireless flying Local Area Network (LAN). Alternative PDU bundling and compression techniques are studied under various metrics including slack time, travel time, queue length, and collision rate. Based on these results, Packet Alloying, a technique for the optimized bundling of packets, is proposed and evaluated. Packet Alloying becomes more active when it is …

Ninebanded Armadillo (Dasypus Novemcinctus), Michael T. Mengak
United States Department of Agriculture Wildlife Services: Staff Publications
Scientists classify armadillos with anteaters and sloths. This tells us that they have poorly developed teeth and limited mobility. In fact, armadillos have small, peg-like teeth that are useful for grinding their food but of little value for capturing prey. No other mammal in Georgia has bony skin plates or a “shell”, which makes the armadillo easy to identify. Just like a turtle, the shell is called a carapace. Armadillos are common in central and southern Georgia and are moving northward. Only one species of armadillo lives in Georgia and the southeastern U.S. However, 20 recognized species are found throughout …
Trends In North American Vulture Populations, Michael L. Avery
Trends In North American Vulture Populations, Michael L. Avery
United States Department of Agriculture Wildlife Services: Staff Publications
In recent years, interactions between vultures and human activities have noticeably increased. These interactions include nuisance roosts, damage to homes and businesses, livestock depredation, and collisions with aircraft. One major factor contributing to the upsurge in vulture problems is higher numbers of these birds. Both turkey vultures and black vultures appear to be experiencing major population increases throughout much of their ranges in the United States. During 1990-2002, Christmas Bird Count (CBC) data revealed annual nationwide increases of 1.79% and 5.97% for turkey wltures and black vultures, respectively. Estimates *om Breeding Bird Survey (BBS) data were 1.99% and 4.97% for …

Use Of Roadkill Data To Index And Relate Raccoon Activity At A Heavily Predated, High-Density Marine Turtle Nesting Beach, Richard M. Engeman, Henry T. Smith, William J.B. Miller
United States Department of Agriculture Wildlife Services: Staff Publications
Four years of data from a high-density marine turtle nesting beach at John D. MacArthur Beach State Park, Florida were examined along with data on raccoon road-kills from adjacent roads, and data on park attendance (as an index of local traffic) to make inferences about raccoon activity patterns relative to turtle nesting. Raccoon road-klls were found to diminish substantially during turtle nesting, even though local traffic was constant or increasing. Opossums, the only other mammal consistently found as road-kills, did not show a decrease during turtle nesting season, but they are not known as a primary predator of turtle nests. …

Monetary Valuation Of Rare Species And Imperiled Habitats As A Basis For Economically Evaluating Conservation Approaches , Richard M. Engeman, Stephanie A. Shwiff, Henry T. Smith, Bernice Constantin
United States Department of Agriculture Wildlife Services: Staff Publications
Management actions directed towards the conservation of species or habitats are usually measured in resource improvement. Nevertheless, the decision to select and carry out such actions are rooted in the available funding. Therefore, to truly evaluate the benefit/costs of a conservation-directed management action, the resource improvement should be in the same metric as the expenditures. To this end, we describe here a variety of methods for attaching monetary values to rare species and habitats. We also give examples of applications with which we have been involved to demonstrate how such species and habitat valuations have allowed economic analyses of conservation …

Comparison Of Aerodynamic And Radiometric Surface Temperature Using Precision Weighing Lysimeters, Paul D. Colaizzi, Steven R. Evett, Terry A. Howell, Judy A. Tolk
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Radiometric surface temperature (Ts) is commonly used as a surrogate for aerodynamic temperature (To) in computing the sensible heat flux term (H) in the energy balance. However, these temperatures may differ by several degrees, leading to possible errors (especially for large H) and their relationship is not well known. Previous researchers have established empirical and semi-empirical parameterizations of the radiometric roughness length (zor) or some related form (e.g., kBr -1 = ln[zom/zor], where zom is the momentum roughness length). In this paper, we estimated To – T …
