Ability Estimation Under Different Item Parameterization and Scoring Models (open access)

Ability Estimation Under Different Item Parameterization and Scoring Models

A Monte Carlo simulation study investigated the effect of scoring format, item parameterization, threshold configuration, and prior ability distribution on the accuracy of ability estimation given various IRT models. Item response data on 30 items from 1,000 examinees was simulated using known item parameters and ability estimates. The item response data sets were submitted to seven dichotomous or polytomous IRT models with different item parameterization to estimate examinee ability. The accuracy of the ability estimation for a given IRT model was assessed by the recovery rate and the root mean square errors. The results indicated that polytomous models produced more accurate ability estimates than the dichotomous models, under all combinations of research conditions, as indicated by higher recovery rates and lower root mean square errors. For the item parameterization models, the one-parameter model out-performed the two-parameter and three-parameter models under all research conditions. Among the polytomous models, the partial credit model had more accurate ability estimation than the other three polytomous models. The nominal categories model performed better than the general partial credit model and the multiple-choice model with the multiple-choice model the least accurate. The results further indicated that certain prior ability distributions had an effect on the accuracy …

An Analysis of the Effectiveness of Computer Assisted Instruction in General Chemistry at an Urban University. (open access)

An Analysis of the Effectiveness of Computer Assisted Instruction in General Chemistry at an Urban University.

The science-major General Chemistry sequence offered at the University of Houston has been investigated with respect to the effectiveness of recent incorporation of various levels of computer technology. As part of this investigation, questionnaire responses, student evaluations and grade averages and distributions from up to the last ten years have been analyzed and compared. Increased use of web-based material is both popular and effective, particularly with respect to providing extra information and supplemental questions. Instructor contact via e-mail is also well-received. Both uses of technology should be encouraged. In contrast, electronic classroom presentation is less popular. While initial use may lead to improved grades and retention, these levels decrease quickly, possibly due to a reduction in instructor spontaneity.

Application of the Finite Element Method to Some Simple Systems in One and Two Dimensions. (open access)

Application of the Finite Element Method to Some Simple Systems in One and Two Dimensions.

The finite element method (FEM) is reviewed and applied to the one-dimensional eigensystems of the isotropic harmonic oscillator, finite well, infinite well and radial hydrogen atom, and the two-dimensional eigensystems of the isotropic harmonic oscillator and the propagational modes of sound in a rectangular cavity. Computer codes that I developed were introduced and utilized to find accurate results for the FEM eigensolutions. One of the computer codes was modified and applied to the one-dimensional unbound quantum mechanical system of a square barrier potential and also provided accurate results.

Approach to Quantum Information starting from Bell's Inequality (Part I) and Statistical Analysis of Time Series Corresponding to Complex Processes (Part II)

Access: Use of this item is restricted to the UNT Community
I: Quantum information obeys laws that subtly extend those governing classical information, making possible novel effect such as cryptography and quantum computation. Quantum computations are extremely sensitive to disruption by interaction of the computer with its environment, but this problem can be overcome by recently developed quantum versions of classical error-correcting codes and fault-tolerant circuits. Based on these ideas, the purpose of this paper is to provide an approach to quantum information by analyzing and demonstrating Bell's inequality and by discussing the problems related to decoherence and error-correcting. II: The growing need for a better understanding of complex processes has stimulated the development of new and more advanced data analysis techniques. The purpose of this research was to investigate some of the already existing techniques (Hurst's rescaled range and relative dispersion analysis), to develop a software able to process time series with these techniques, and to get familiar with the theory of diffusion processes.

Attrition Rates of Teachers Trained in Alternative Teacher Certification Programs, Those Trained in the Centers for the Professional Development of Teachers, and Those Trained in Traditional University Programs.

Access: Use of this item is restricted to the UNT Community
This study uses teacher employment data provided by the State Board for Educator Certification to examine the similarities and differences between initial employment and attrition rates of teachers trained in three prevalent types of Texas teacher preparation programs; alternative certification programs (ACP), the centers for professional development of teachers (CPDT), and traditional certification programs (TCP). The population for the study includes all Texas teachers who completed training in these programs in 1995, 1996, and 1997. The study found that ACP participants gain employment as Texas public school teachers at a significantly higher rate than their CPDT and TCP trained peers in year-one after completion of their training. However, ACP completers experience higher attrition rates in each of the subsequent years investigated. The study concludes that the overall cumulative attrition rate of new teachers trained in these programs is not as pronounced as originally presumed, but that low production levels cannot keep up with the growing demand for new teachers. Teacher preparation program leaders must seek ways to recruit and train more teachers.

Autoradiographic Localization of Carbachol-Induced Second Messenger Response in the Rat Spinal Cord Following Inflammation. (open access)

Autoradiographic Localization of Carbachol-Induced Second Messenger Response in the Rat Spinal Cord Following Inflammation.

This study examined central mechanisms of persistent pain using an autoradiographic technique to localize phosphoinositide hydrolysis (PI) in the rat spinal cord dorsal horn. The lateral half of laminae I-II showed the highest levels of baseline PI turnover and carbachol-stimulated PI turnover in normal animals as well as after inflammation. Inflammation resulted in increased baseline PI turnover in this region of the ipsilateral (76%) and contralateral (65%) dorsal horns. Carbachol increased PI turnover in this region in normal rats (55%) and following inflammation (ipsilateral: 46%, contralateral: 45%). The absolute magnitudes of these increases were 1.85, 2.71, and 2.51 nCi/mg, respectively. The results of this study demonstrate the involvement of PI turnover in neural mechanisms of persistent pain, and provide evidence for the involvement of cholinergic systems in this process. Because spinal cholinergic systems have been reported to be anti-nociceptive, the present results appear to reflect an upregulation of anti-nociceptive activity in response to inflammation. Thus, the spinal cholinergic system may be a regulatory site within the anti-nociceptive pathway, and may provide an attractive target for the development of new therapeutic agents.

A Behavioral Economic Analysis of the Effects of Unit Price Sequence on Demand for Money in Humans. (open access)

A Behavioral Economic Analysis of the Effects of Unit Price Sequence on Demand for Money in Humans.

Three groups of participants were exposed to different unit price sequences. Unit prices for all groups ranged from unit price 1 to 21. Analyses of demand curves, response rates, session duration, and elasticity coefficients suggest that the sequence of exposure to unit prices can affect the elasticity of demand. In addition, the size of unit price contrast, direction of unit price change, and proximity to experimental milestones also may affect the consumption of monetary reinforcers.

Bioreactor Landfill Cell Feasibility Study ' Reference to City of Denton Subtitle-D Permit #1590A Landfill (open access)

Bioreactor Landfill Cell Feasibility Study ' Reference to City of Denton Subtitle-D Permit #1590A Landfill

The City of Denton Landfill, Permit #1590A, utilizes “Dry-Tomb” techniques for disposal and promotion of municipal solid waste stabilization, as described by the Resource Conservation and Recovery Act (RCRA) prohibition in 40 CFR. Bioreactor research suggests re-circulating leachate increases biodegradation rates and reduces long-term monitoring from fifty years to less than ten years. Current procedures that are followed at Denton's landfill, literature review and the use of the Hydrologic Evaluation of Landfill Performance (HELP) model, suggest that a bioreactor landfill cell is worthy of further research. Re-circulating leachate and augmenting it with additional liquid will increase biodegradation and the need to design and build a landfill gas collection system to capture methane for energy recovery uses.

Burying the War Hatchet: Spanish-Comanche Relations in Colonial Texas, 1743-1821

Access: Use of this item is restricted to the UNT Community
This dissertation provides a history of Spanish-Comanche relations during the era of Spanish Texas. The study is based on research in archival documents, some newly discovered. Chapter 1 presents an overview of events that brought both people to the land that Spaniards named Texas. The remaining chapters provide a detailed account of Spanish-Comanche interaction from first contact until the end of Spanish rule in 1821. Although it is generally written that Spaniards first met Comanches at San Antonio de Béxar in 1743, a careful examination of Spanish documents indicates that Spaniards heard rumors of Comanches in Texas in the 1740s, but their first meeting did not occur until the early 1750s. From that first encounter until the close of the Spanish era, Spanish authorities instituted a number of different policies in their efforts to coexist peacefully with the Comanche nation. The author explores each of those policies, how the Comanches reacted to those policies, and the impact of that diplomacy on both cultures. Spaniards and Comanches negotiated a peace treaty in 1785, and that treaty remained in effect, with varying degrees of success, for the duration of Spanish rule. Leaders on both sides were committed to maintaining that peace, although …

Carl Gottlieb Reissiger (1798-1859) Forgotten Composer for the Clarinet (open access)

Carl Gottlieb Reissiger (1798-1859) Forgotten Composer for the Clarinet

Carl Gottlieb Reissiger was a successful German composer, conductor, and teacher in the first half of the nineteenth century. At the height of his career, he was Hofkapellmeister of theater and opera in Dresden, a position he held until his death. He was a composer of more than 200 works in a multitude of different genres. Today he is mainly known as a composer of opera, a small portion of his total output as a composer. He wrote approximately eighty piano solos, eighty collections of songs or duets, nine masses, and many smaller sacred choral works, as well as 27 piano trios, seven piano quartets, and three piano quintets. In addition to these many works, he wrote five works for the clarinet: Concertino, op. 63, Duo Brillant for clarinet and piano, op. 130, Fantasie, op. 146, Second Fantasie, op. 180, and Adagio und Rondo alla polacca, op. 214. This document provides a biographical sketch of Reissiger, including his personal life, his life as a conductor, and his life as a composer. It also provides a look at the artistic life of his day: his fellow composers and the music they were writing for clarinet, outstanding clarinetists and the different instruments …

The Characteristics of Sociological Practitioners: A Social Psychological Examination (open access)

The Characteristics of Sociological Practitioners: A Social Psychological Examination

Questionnaires were sent by mail and e-mail to 143 members of the Sociological Practice Association. The purpose of the questionnaire was to measure the role expectations as qualities (competencies), role expectations as actions, and role enactments of the respondents'. An additional goal was to examine how respondents perceived their work to be sociological in nature, and how they saw their work as different from the practices of social workers, counselors, and psychologists. The first question that was addressed was, “Do sociological practitioners have clear and unambiguous role expectations for their work as practitioners?” The data showed that most role expectations measured as competencies were clear and unambiguous, and only a few were ambiguous and unclear. The second question addressed was, “Do sociological practitioners perceive their role enactments to differ from other helping professionals such as social workers, counselors, and psychologists?” The data showed that sociological practitioners do perceive their role enactments to be different because of their use of sociological theory and their focus on social structures. The final question asked was, “How do sociological practitioners perceive their work as sociological in theory, methods, or both?” The data showed that sociological practitioners perceive their work as sociological based on their …

Characterization of cDNA and Genomic Clones for a Palmitoyl-acyl Carrier Protein Thioesterase and an Osmotin-Like PR5 Protein in Gossypium Hirsutum.

Access: Use of this item is restricted to the UNT Community
Putative cotton cDNA clones and cognate genomic clones for a palmitoyl-acyl carrier protein (ACP) thioesterase (PATE) and an osmotin-like pathogenesis-related 5 (PR5) protein have been isolated and characterized. PATE is a class B fatty acid thioesterase with specificity for saturated long-chain fatty acids such as palmitate, and is implicated as a key enzyme to be targeted for regulation of fatty acid synthesis in order to alter cotton seed oil profiles. A nearly full-length 1.7-kb cDNA clone was isolated using a hybridization probe derived from an Arabidopsis PATE cDNA clone designated TE 3-2. A 17-kb genomic segment encompassing the PATE gene was also isolated, which has six exons and five introns with high sequence identity with other FatB cDNA/gene sequences. The deduced PATE preprotein amino acid sequence of 413 residues has putative signal sequences for targeting to the chloroplast stroma. PR5 proteins called osmotins are made in response to fungal pathogen stress or osmotic stress (water deprivation or salt exposure). Osmotins may actually form pores in fungal membranes, leading to osmotic rupture and destruction of the fungal cells. A cotton osmotin-like PR5 cDNA insert of 1,052 base-pairs was isolated and shown to encode a preprotein of 242 amino acids and is …

College Freshman Biology Two Semester Course: Integrating Deep Processing Teaching Techniques (open access)

College Freshman Biology Two Semester Course: Integrating Deep Processing Teaching Techniques

Development of a college level freshman biology course was undertaken in response to government reports that American students have fallen behind students of other countries in the area of the sciences. Teaching strategies were investigated to accomplish two objectives, to define essential academic material to include in the course and to investigate teaching techniques that would increase deep processing of the information. An active process that consisted of applying the cognitive information to solving problems or developing answers to questions was defined as critical thinking. Critical thinking was incorporated into the course by the use of case studies.
