The purpose of this research was to examine how Hispanic high school students represent their experiences in one college readiness program, Advancement Via Individual Determination (AVID), which is designed to prepare students in the academic middle for four-year college. Utilizing social and cultural capital theories, I examined student perspectives on the supports AVID provided for them to gain the social and cultural capital needed for success in school and entry to college. I conducted eight forty-five minute semistructured interviews grounded in an ethnographic perspective. Eight participating AVID students came from low socioeconomic backgrounds, were Hispanics in the academic middle (GPA …

First Generation Hispanic High School Students Going To College: Experiences That Support Decisions And College Going Pathways, Norma Ibarra-Cantú

Theses and Dissertations - UTB/UTPA

In this study I examined the question: How do first generation Hispanic high school students decide to attend college? To understand how the students made college decisions and what supported their pursuit of college aspirations, I interviewed six Hispanic high school students from five different high schools in a south Texas-Mexico border town. Student participants were the first generation in their immediate family to graduate from high school and to consider going to college. I conducted qualitative open-ended interviews with each of the participants and used inductive multilayered analyses to identify how students made decisions to attend college and how …

Design And Implementation Of An Actively Adjustable Spring Mechanism Via Redundant Actuation, Eleazar Marquez

Theses and Dissertations - UTB/UTPA

This study presents the theoretical results and experimental validation of an adjustable stiffness mechanism. The use of redundant actuation is emphasized in the design of a one-degree-of-freedom Watt II mechanism capable of independently controlling the effective stiffness without a change in equilibrium position. This approach is in contrast to previous spring mechanism designs unable to actively control the spring rate independent of deflection, and has potential applications in various types of suspension and assembly systems. Results indicate that driving the redundantly actuated, unidirectional, spring mechanism requires attaching two direct brush-type direct current motors on each of the two grounded revolute …

A Study Of The Effect Of Vibration On Railroad Bearing Temperature, Bertha Alicia Gonzalez

Theses and Dissertations - UTB/UTPA

An on-track collaborative field test and laboratory experiments were conducted in order to determine the relationship between abrupt rises in surface temperature of a railroad bearing and vibration signatures captured during the experiments. The collaborative field test was conducted in order to investigate the root cause for this abrupt temperature change known as bearing temperature trending. The research presented in this thesis will show that temperature trending is correlated to an increase in the magnitude of vibration within the bearing and the fundamental frequencies that are generated by the internal components of a rotating bearing assembly. Distinct vibration mechanisms are …

A Critical Analysis Of The Identification, Placement, And Assessment Policies For Achieving Educational Parity Of Bilingual Learners, Lilia Rocio Estrada

Theses and Dissertations - UTB/UTPA

This study analyzed the process of proper identification, placement, and assessment of Bilingual Learners (BLs) by investigating the perceptions of members in the Texas Language Proficiency Assessment Committee (LPAC). The findings focused on LPAC perceptions of their decisions to identify, place, and assess BLs as well as how these compared among members with different positions. Also, the LPAC members’ perceptions from schools that followed a dual language education program were compared to those schools that followed a transitional bilingual education program. It was found that majority of LPAC members lacked the confidence in assessing BLs, LPAC members holding higher positions …

Photonic Crystal Design And Fabrication Assisted By Tunable Femtosecond Oscillator Laser, Kristofer B. Ohlinger

Theses and Dissertations - UTB/UTPA

Photonic Crystals have the potential for engineered light interaction as directed by the photonic bandgap, a property that details the prohibited propagation region and ultimately the ability to guide light. A so called, photonics-on-chip, would incorporate arbitrary light guiding with functional elements in one package. The realization of such a device is subject to the fabrication paradigms implemented and this thesis is concerned with holographic lithography as a means for creating polymer photonics crystal templates and two-photon polymerization for incorporating light guiding pathways.

In this thesis, the design of the to-be-fabricated structures has been co-opted by computational exploration of the …

The Conservative Conversation, Heather Hall

Theses and Dissertations - UTB/UTPA

The conservative movement is defined by its ideology as well as its rhetoric. Richard Weaver’s conversion to the Right offers an opportunity to define conservatism and conservative rhetoric through his hierarchy of argumentation, and his examination of Plato’s Phaedrus allows an examination of the speaker’s nature and the nature of rhetoric. Glenn Beck, one of today’s most controversial conservative representatives, also deserves examination for his ideology and rhetoric. Both Richard Weaver and Glenn Beck bear scrutiny as influential members of the conservative movement and the role their rhetoric has in the conservative conversation today.

Predicting College Student Classroom Performance With A Simple Metacomprehension Scale, Amber Lee Klein

Theses and Dissertations - UTB/UTPA

The present study investigated the relationship between college student metacomprehension and the error of predicted classroom performance. College student metacomprehension was evaluated using the Metacomprehension Scale (MCS) designed by Moore, Zabrucky, and Commander (1997a). Prior to an examination administered by a course instructor, covering course content, students predicted the percentage score he/she expected to achieve. The predicted score was subtracted from the obtained score generating an error score. It was hypothesized that error of predicted classroom performance is a function of student metacomprehension, as measured by the MCS. Results indicate the MCS was not a reliable indicator of student predicted …

False Positive Rates In The Neuropsychological Assessment Of Neurologically Intact Bilingual Hispanic American Adults, Cassandra Dayanira Gonzalez

Theses and Dissertations - UTB/UTPA

Hispanic Americans perform more poorly than White Americans on neuropsychological tests, leading to a higher misclassification rate of brain injury (false positives) among Hispanics when using the 50th percentile of published norms as the estimate of preexisting neuropsychological skill. This study aimed to determine if using an individual comparison standard to estimate preexisting skill levels would reduce the number of false positives in a sample of 20 bilingual Hispanic American adults. Two individual comparison standards were used: (a) WMLS-R Picture Vocabulary scores, and (b) WMLS-R Picture Vocabulary scores and WAIS-III Matrix Reasoning scores combined. Both individual comparison standards were found …

The Use Of Securities Data In Determining Discount Rates For Real Property, Hal B. Heaton

Faculty Publications

When the income approach is used to value real property, appraisers forecast anticipated cash flows from the property and discount those cash flows to arrive at a present value. To do this, appraisers must determine an appropriate rate for discounting the future cash flows. Market value is usually defined as the price between a willing buyer and a willing seller. Appraisers therefore should study the market for the type of properties involved to determine the discount rates used by buyers and sellers of those properties in actual transactions.

Provide Visual Structure For Students With Asd, Tina Taylor

Faculty Publications

World renowned animal scientist and autism self-advocate Temple Grandin said, "People on the autism/Asperger spectrum have uneven skills. They are often good at one type of learning and bad at another. Educators need to work on building up the area of strength." She explains that three cognitive areas of strength are those who are visual thinkers, pattern thinkers, and word thinkers. Visual thinkers are more inclined to think in pictures rather than words. They may excel in graphic design, industrial design, animation, geometry, or trigonometry. Pattern thinkers have abstract visual thoughts where they can see patterns and relationships between numbers. …

Measured And Estimated Ground Reaction Forces For Multi-Segment Foot Models, Dustin A. Bruening, Kevin M. Cooney, Frank L. Buczek

Faculty Publications

Accurate measurement of ground reaction forces under discrete areas of the foot is important in the development of more advanced foot models, which can improve our understanding of foot and ankle function. To overcome current equipment limitations, a few investigators have proposed combining a pressure mat with a single force platform and using a proportionality assumption to estimate subarea shear forces and free moments. In this study, two adjacent force platforms were used to evaluate the accuracy of the proportionality assumption on a three segment foot model during normal gait. Seventeen right feet were tested using a targeted walking approach, …

Regulatory Focus, Regulatory Fit, And The Search And Consideration Of Choice Alternatives, Michel Tuan Pham, Hannah H. Chang

Research Collection Lee Kong Chian School Of Business

This research investigates the effects of regulatory focus on alternative search and consideration set formation in consumer decision making. Results from three experiments yield two primary findings. First, promotion-focused consumers tend to search for alternatives at a more global level, whereas prevention-focused consumers tend to search for alternatives at a more local level. Second, promotionfocused consumers tend to have larger consideration sets than do preventionfocused consumers. Building on these two primary findings, it is additionally shown that whereas promotion-focused consumers attach relatively greater value to options chosen from hierarchically structured sets, prevention-focused consumers attach relatively greater value to options chosen …

Integrating Ioob And Jdm Through Process-Oriented Research, Jochen Reb

Research Collection Lee Kong Chian School Of Business

One of the most fascinating and counterintuitive insights from negotiation theory is that differences, rather than similarities, open up opportunities for value creation (Raiffa, 2002). Because of different values, beliefs, and perspectives, parties can benefit from their complementarities. Ironically though, negotiators tend to prefer negotiating with similar others, with others they like, presumably because negotiators expect interactions to proceed more smoothly. Differences make interaction more difficult but also potentially more rewarding, if managed correctly.

Testing Structural Change In Partially Linear Models, Liangjun Su, Halbert White

Research Collection School Of Economics

We consider two tests of structural change for partially linear time-series models. The first tests for structural change in the parametric component, based on the cumulative sums of gradients from a single semiparametric regression. The second tests for structural change in the parametric and nonparametric components simultaneously, based on the cumulative sums of weighted residuals from the same semiparametric regression. We derive the limiting distributions of both tests under the null hypothesis of no structural change and for sequences of local alternatives. We show that the tests are generally not asymptotically pivotal under the null but may be free of …
