Funds Budgeted for Educational Programs in Texas Schools during a Period of Changing Enrollment

Description: This study analyzes budgets of Texas school districts experiencing declining enrollments, as opposed to districts with increasing or steady enrollments. This study identifies how schools are expending funds to meet those needs while dealing with enrollment changes. A total of 924 school districts are studied. The changes in average daily attendance from 1993-1994 to 2003-2004 are used to categorize each district as having increasing, stable, or decreasing enrollments. The total dollar amount expended is compared to the total number of students in each district to determine the amount expended per student. The amounts expended for special education career and technology education, bilingual education, and compensatory education are compared to the number of students being served by those programs to determine a dollar amount that can also be compared from the 1993-1994 and 2003-2004 school years. The per-student expenditures for each educational program are compared to the overall per-student expenditures in each enrollment category (increasing, stable, decreasing). The study reveals no clear pattern of change in the comparison of overall spending to individual program spending as district enrollments fluctuated.

Funds of Knowledge and Early Literacy: A Case Study

Description: When teachers are charged with educating students that are racially, culturally, or economically different from them, they may have little information on the culture and type of family involvement of their students. This lack of information contributes to perceptions of working-class families as socially disorganized and intellectually deficient. However, research embodying the theoretical framework funds of knowledge (FoK) attempts to counter deficient models through its assertion that all families possess extensive bodies of knowledge that have developed through social, historical, political, and economic contexts. The primary purpose of this study was to carefully examine Hispanic parents’ support of young children’s early literacy development in the home. The knowledge gleaned from an initial study of home support, by spending time in the home of a Hispanic family provided an avenue for action research in the classroom. A second purpose was to determine if the introduction of FoK ways of learning, when applied in the classroom, had an effect on early literacy skills. In addition, I maintained a journal that chronicled my experiences and led to an autoethnographic study of myself as a transforming white, female, prekindergarten teacher. The results indicated that the family possessed extensive FoK developed through historical, cultural, educational, and social experiences. Results further indicate that introduction of these familial FoK improved the oral language skills of prekindergarten students thus enhancing their early literacy development. Autoethnographic results indicate a personal progression toward not only understanding, but becoming an advocate, for the Hispanic population.

Funds of Knowledge in a Hispanic Household: a Case Study of Family Experiences, Values, and Connections to Education

Description: Traditionally, the field of education has often adopted a negative perspective in their views of minority families’ contributions to the educational progress of their children. However, research embodying the theoretical framework of ‘funds of knowledge’ attempts to counter that model through its assertion that all families possess extensive bodies of knowledge that have developed through social, historical, and cultural contexts. Teachers carry out studies of familial funds of knowledge in order to understand how family experiences shape the knowledge that a child brings to the classroom. There is then, the potential to use that body of knowledge to create meaningful learning experiences that connect prior understanding and experiences to classroom practice. This research served as a case study of the funds of knowledge existing in the home of a Hispanic family and the connections that existed between that knowledge and literacy. The results indicated that the family possessed extensive funds of knowledge that developed through their historical, cultural, and social experiences. They often used family networks, as well as formal and informal literacy experiences to share this knowledge with their children. A key component of the literacy value system that they communicated resulted from a desire to maintain aspects of their culture and heritage through maintaining and improving their children’s reading and linguistic abilities in Spanish. Furthermore, along with their emphasis on Spanish literacy, they held aspirations for their children related to familial and educational values that often stemmed from their expressed desire for their children to lead lives with greater opportunities and positive examples than they had experienced.

Further Evaluation of Blocked Trials to Teach Intraverbal Conditional Discriminations: Effects of Criterion-level Probes

Description: Individuals with autism often have deficient intraverbal repertoires. Previous research has found success in using a blocked trials procedure to facilitate discrimination training. A previous study (unpublished) from our laboratory extended this procedure to intraverbal training. The current study continued this line of research by exploring the outcomes of probing the criterion performance more frequently. Three children with autism, ages 7-13, participated. Eight question pairs were taught. One question was presented repeatedly until a specified number of consecutive correct responses occurred, then the other question was presented. Contingent on specific mastery criteria, the trial blocks were faded into smaller blocks until the questions were presented in quasi-random order. Between each step, a criterion probe was conducted to determine if further steps were necessary. The procedure has been successful for two of the three participants. Criterion probe performance showed that not all teaching steps were needed every time. The procedure may have facilitated acquisition over time, because the number of trials to mastery generally decreased over successive targets.

A Futile Quest for a Sustainable Relationship in Welty's Short Fiction

Description: Eudora Welty is an author concerned with relationships between human beings. Throughout A Curtain of Green and Other Stories, The Wide Net and Other Stories, and The Golden Apples, Welty's characters search for ways in which to establish and sustain viable bonds. Particularly problematic are the relationships between opposite sexes. I argue that Welty uses communication as a tool for sustaining a relationship in her early work. I further argue that when her stories provide mostly negative outcomes, Welty moves on to a illuminate the possibility and subsequent failure of relationships via innocence in the natural world. Finally, Welty explores, through her characters, the attempt at marginalization and the quest for relationships outside the culture of the South.

The future of local television news: Is there a possible strategic planning approach?

Description: This study compared the characteristic of strategic planning as used in the corporate world with the planning process used in a sample of television news departments. The purpose was to determine if commonalities exist; in what circumstances, and whether techniques and approaches used for many years by businesses could advance the process of planning in the fast-paced environment of local television news. In-depth interviews were conducted with a sample of highly experienced local news managers. The results indicated some similarities in planning approaches but suggested significant differences in how the two industries approach key elements of traditional strategic planning. The primary conclusion drawn from the research suggests the local television news industry has informally adapted strategic planning processes to their needs with heavy emphasis on tactical execution.

Futures-Forward Price Differences and Efficiency in the Treasury Bill Futures Market

Description: This study addressed two issues. First, it examined the ability of two models, developed by Cox, Ingersoll and Ross (CIR), to explain the differences between futures and implicit forward prices in the thirteen-week T-bill market. The models imply that if future interest rates are stochastic, futures and forward prices differ; the structural difference is due to the daily settlement process required in futures trading. Second, the study determined the efficiency of the thirteen-week T-bill futures market using volatility and regression tests. Volatility tests use variance bounds to examine whether futures prices are excessively volatile for the market to be efficient. Regression tests investigate whether futures prices are unbiased predictors of future spot prices. The study was limited to analysis of the first three futures contracts, using weekly price data as reported in the Wall Street Journal from March, 1976 to December, 1984. Testing of the first CIR model involved determination of whether changes in futures-forward price differences are related to changes in local covariances between T-bill futures and bond prices. The same procedure applied in testing the second model with respect to changes in futures-forward price differences, local covariances between T-bill spot and bond prices, and local variances of bond prices. Volatility tests of market efficiency involved comparison of mean variances on both sides of two inequality equations. Regression tests involved determination of whether slope coefficients are significantly different from zero.

G. K. Chesterton: Twentieth Century Catholic Reformer

Description: This thesis attempts to discover the basis of Chesterton's theories and the link between his religion and politics. The main sources for this paper are the religious and political non-fiction works by Chesterton and his collaborators. The first chapter brings G. K. from his birth in 1874 to 1908 and the publication of Orthodoxy. The second chapter describes his conversion to Roman Catholicism, and the third discusses his distinctive Christian theology. The fourth outlines G. K.'s political solution for Englands economic and social ills and how his theory--distributism-- fit into British intellectual tradition. The conclusion identifies G. K.'s romance with the Middle Ages as the link between his religious beliefs and his political utopia.

Galician Daily Life and Social Customs as Seen in Pardo Bazan's Rural Short Stories

Description: In the portrayal of the Galician people Pardo Bazán's naturalistic pessimism is more evident than in her descriptions of customs or landscape. Her characters are stifled and often shattered by living conditions. The environment weighs heavily upon them, bringing forth the more despicable aspects of human behavior. In spite of this, she succeeds in probing the soul of her countrymen and giving them life in her short stories.

Galileo's Eyeglass: An Orchestral Work Celebrating the Discovery of the Moons of Jupiter and the Rings of Saturn

Description: Galileo's Eyeglass is a celebratory work for full orchestra with standard instrumentation commemorating Galileo Galilei's discoveries of the four largest moons of Jupiter and the rings of Saturn in 1610. The composition is approximately 14 minutes in duration, and although divided thematically into four parts, the music is continuous. The work exhibits primarily a blend of contemporary styles and compositional elements, yet it is rooted in traditional tonality; furthermore, the piece is interspersed with references to Galileo's life and times, including quotations of a toccata composed by the scientist's brother, Michelangelo Galilei, transcribed from lute tablature. Chapter 1 of Part 1 investigates relevant historical threads extracted from the backdrop of Galileo's life, from reflections on the events that shape the musical program, to the selection and preparation of the period music composed by Galileo's brother. Chapter 2 discusses specific musical components of Galileo's Eyeglass, including form, musical quotations, motivic and thematic material, harmonic language, orchestration, and notation. Chapter 3 examines the principal philosophical themes behind the composition, including expressions of victory of a life well lived in spite of many obstacles. Part 2 contains the orchestral score.

Galvanomagnetic Determination of Energy Bands in Arsenic

Description: A study of the transport properties of a substance requires the determination of a set of transport coefficients by experiment. From these coefficients, the elements of the electrical conductivity tensor, thermoelectric tensor, et cetera can be determined. In this experiment, measurements and analyses of galvanomagnetic effects in a single crystal of arsenic were performed. The measurements were made at liquid-helium temperatures in magnetic fields ranging to 25 kilogauss. The gross isothermal, electrical conductivities have been analyzed to determine various parameters characterizing the energy bands in arsenic.

Gamma Prime Precipitation Mechanisms and Solute Partitioning in Ni-base Alloys

Description: Nickel-base superalloys have been emerged as materials for gas turbines used for jet propulsion and electricity generation. The strength of the superalloys depends mainly from an ordered precipitates of L12 structure, so called gamma prime (γ’) dispersed within the disorder γ matrix. The Ni-base alloys investigated in this dissertation comprise both model alloy systems based on Ni-Al-Cr and Ni-Al-Co as well as the commercial alloy Rene N5. Classical nucleation and growth mechanism dominates the γ’ precipitation process in slowed-cooled Ni-Al-Cr alloys. The effect of Al and Cr additions on γ’ precipitate size distribution as well as morphological and compositional development of γ’ precipitates were characterized by coupling transmission electron microscopy (TEM) and 3D atom probe (3DAP) techniques. Rapid quenching Ni-Al-Cr alloy experiences a non-classical precipitation mechanism. Structural evolution of the γ’ precipitates formed and subsequent isothermal annealing at 600 °C were investigated by coupling TEM and synchrotron-based high-energy x-ray diffraction (XRD). Compositional evolution of the non-classically formed γ’ precipitates was determined by 3DAP and Langer, Bar-on and Miller (LBM) method. Besides homogeneous nucleation, the mechanism of heterogeneous γ’ precipitation involving a discontinuous precipitation mechanism, as a function of temperature, was the primary focus of study in case of the Ni-Al-Co alloy. This investigation coupled SEM, SEM-EBSD, TEM and 3DAP techniques. Lastly, solute partitioning and enrichment of minor refractory elements across/at the γ/ γ’ interfaces in the commercially used single crystal Rene N5 superalloy was investigated by using an advantage of nano-scale composition investigation of 3DAP technique.
