Academic Achievement As A Function Of Attributions Of Success And Failure And Socio-Cultural Variables In Mexican-American Students, Mary Alice Reyes

Theses and Dissertations - UTB/UTPA

The purpose of this research was to examine Mexican-American 8th grade students' attributions of success and failure in school-related contexts. The relationship between and among these attributions, socio-cultural variables and academic achievement was also explored and analyzed. Attribution theory formed the theoretical foundation for the study.

The study utilized three instruments as the primary sources of self-reported data: the Texas Assessment of Academic Skills (TAAS ), Student Achievement Responsibility Survey ( SARS ) (Ryckman, 1985), and the Short Acculturation Scale for Hispanic Youth ( SASH-Y ) (Barona & Miller, 1994). Other data including gender and migrant status were obtained from …

Automated Robotic Inspection System For Electronic Manufacturing, Roberto Alejandro Balderas

Theses and Dissertations - UTB/UTPA

An automated robotic inspection system for electronic manufacturing has been developed to identify pin defects of IC packages mounted on printed circuit boards using surface mount technology. The automated robotic inspection system consists of two robots, a computer, a CCD camera with frame gabber for image acquisition, and a customized windows program using neural network for on-line defect identification. Gray scale images of the pins on IC packages are acquired using ambient light. The images are filtered and formatted to appropriate size, so that Matlab neural network tool could be used. The images are used to train neural networks using …

Tightness Of Slip-Linked Polymer Chains, Ralf Metzler, Andreas Hanke, Paul G. Dommersnes, Yacov Kantor, Mehran Kardar

Physics & Astronomy Faculty Publications

We study the interplay between entropy and topological constraints for a polymer chain in which sliding rings (slip links) enforce pair contacts between monomers. These slip links divide a closed ring polymer into a number of subloops which can exchange length among each other. In the ideal chain limit, we find the joint probability density function for the sizes of segments within such a slip-linked polymer chain (paraknot). A particular segment is tight (small in size) or loose (of the order of the overall size of the paraknot) depending on both the number of slip links it incorporates and its …

Group-Fitted Ab Initio Single- And Multiple-Scattering Exafs Debye-Waller Factors, Nicholas Dimakis, Grant Bunker

Physics & Astronomy Faculty Publications

X-ray absorption fine structure (XAFS) spectroscopy is one of the few direct probes of the structure of metalloprotein binding that is equally applicable to proteins in crystals, solutions, and membranes. Despite considerable progress in the calculation of the photoelectron scattering aspects of XAFS, calculation of the vibrational aspects has lagged because of the difficulty of the calculations. We report here initial results that express single- and multiple-scattering Debye-Waller factors as polynomial functions of first shell radial distance for metal-peptide complexes, enabling quantitatively accurate full multiple-scattering XAFS data analysis of active sites of unknown structure at arbitrary temperatures without the use …

Correlation Functions Near Modulated And Rough Surfaces, Andreas Hanke, Mehran Kardar

Physics & Astronomy Faculty Publications

In a system with long-ranged correlations, the behavior of correlation functions is sensitive to the presence of a boundary. We show that surface deformations strongly modify this behavior as compared to a flat surface. The modified near surface correlations can be measured by scattering probes. To determine these correlations, we develop a perturbative calculation in the deformations in height from a flat surface. Detailed results are given for a regularly patterned surface, as well as for a self-affinely rough surface with roughness exponent ζ. By combining this perturbative calculation in height deformations with the field-theoretic renormalization-group approach, we also estimate …

The Effects Of Inclusion On Learning-Disabled Students' Self-Esteem, Ruth Ann Cardoza

Theses and Dissertations - UTB/UTPA

This study was to determine whether Learning Disabled students who receive all their instruction in regular education would receive significantly higher self-esteem scores than students who receive services from special education resource. The instruments employed were the Coopersmith Self-Esteem Inventory and the Pier-Harris Self-Concept Scale in order to determine any significant differences in self-esteem between the two groups. The sample consisted of 30 bilingual Mexican-American children ages 8–12. The subjects were from public schools in the southern region of Texas on the Mexico-Texas border. Data were analyzed through descriptive statistics, T-test, and two-way factorial analysis of variance with repeated measures. …

Relationship Between Cognitive Performance And Sociocultural And Linguistic Variables In Bilingual Mexican American Children, Lorraine Geralyn Boudville

Theses and Dissertations - UTB/UTPA

This study investigated the relationship between cognitive ability (dependent variable) and 5 independent variables: acculturation, socioeconomic status (SES), oral acquisition of syntactic structures, family size, and family structure. Instruments used were the WISC-III, Bilingual Syntax Measure (BSM), Sociocultural Scales in the System of Multicultural Pluralistic Assessment (SOMPA). The sample consisted of 96 bilingual Mexican American children aged six and seven years, randomly selected from five school districts in south Texas; 47 were female, and 49, male. The method of analysis was multiple linear regression. The null hypothesis was tested at the .05 level of significance, using a F distribution. Results …

Gallos, Caballos, Gente Y Paisajes, Rosendo Sandoval

Theses and Dissertations - UTB/UTPA

First. I will give the reader a brief but detailed biography. It covers the period of time from my birth all the way to my college graduation. This section gives the reader an idea about my beginnings as an artist, and about the hardships that I have endured during my lifetime.

Second, this paper talks about the work, and my main sources of inspiration. In it I explain to the reader what have been my sources of inspiration from childhood all the way to the present time. One of my first sources of inspiration were the old Mexican movies that …

The First Detection Of Coherent Emission From Radio Pulsars, F. A. Jenet, S. B. Anderson, T. A. Prince

Physics & Astronomy Faculty Publications

The statistical properties of the radio emission from the pulsars B0823+26, B0950+08, B1133+16, and B1937+21 are studied using high time resolution observations taken at the Arecibo Observatory in Puerto Rico. Temporally coherent non-Gaussian emission has been detected in three of the four observed objects. This is the first time such a phenomenon has been observed. The results have been interpreted using a generalized shot noise model, and various basic physical quantities pertaining to the magnetospheric plasma have been estimated.

Data Conditioning For Gravitational Wave Detectors: A Kalman Filter For Regressing Suspension Violin Modes, L. S. Finn, S. Mukherjee

Physics & Astronomy Faculty Publications

Interferometric gravitational wave detectors operate by sensing the differential light travel time between free test masses. Correspondingly, they are sensitive to anything that changes the physical distance between the test masses, including physical motion of the masses themselves. In ground-based detectors the test masses are suspended as pendula, in order that they be approximately \"free\" above the pendulumn frequency. Still, thermal or other excitations of the suspension wires' violin modes do impart a force on the masses that appears as a strong, albeit narrow-band, \"signal\" in the detectors waveband. Gravitational waves, on the other hand, change the distance between the …
