Early Predictors of Early Freshman Year Attrition in Female Hispanic Students
The Texas Hispanic population is projected to grow to 18.8 million, almost tripling its number within the state, in only 30 years. This rapid growth is a concern for Texas higher education because this group has traditionally been under-represented in colleges and universities. Also, according to national, state, and local data, Hispanic students are retained at a lower rate than are other ethnic groups. Because of lower retention rates for Hispanic students and because the majority of Hispanic college students are female, an increasing number of Hispanic women are heads of households. Studying the attrition rates of Hispanic females could provide a better understanding of how the state can improve both the participation and retention rates of this population. This study utilized descriptive statistics and regression analysis to identify the correlations between and among the dependent variable of attrition and independent variables derived from (1) pre-college survey responses measuring college expectations and (2) early-first semester survey responses measuring actual college experience. Institutional data were used to confirm enrollment status at the beginning of the second semester. The sample of the study was all female, full-time, first-time-in college student survey respondents attending a public 4-year institution in Texas. This number included …

Eddy sensors for small diameter stainless steel tubes.
The goal of this project was to develop non-destructive, minimally disruptive eddy sensors to inspect small diameter stainless steel metal tubes. Modifications to Sandia's Emphasis/EIGER code allowed for the modeling of eddy current bobbin sensors near or around 1/8-inch outer diameter stainless steel tubing. Modeling results indicated that an eddy sensor based on a single axial coil could effectively detect changes in the inner diameter of a stainless steel tubing. Based on the modeling results, sensor coils capable of detecting small changes in the inner diameter of a stainless steel tube were designed, built and tested. The observed sensor response agreed with the results of the modeling and with eddy sensor theory. A separate limited distribution SAND report is being issued demonstrating the application of this sensor.

Effect of impedance and higher order chromaticity on the measurement of linear chromaticity
The combined effect of impedance and higher order chromaticity can act on the beam in a nontrivial manner which can cause a tune shift which depends on the relative momenta with respect to the 'on momentum' particle ({Delta}p/p). Experimentally, this tune shift affects the measurement of the linear chromaticity which is traditionally measured with a change of {Delta}p/p. The theory behind this effect will be derived in this paper. Computer simulations and experimental data from the Tevatron will be used to support the theory.

Effect of pH on the Water/{alpha}-Al{sub 2}O{sub 3} (1{bar 1}02) interface structure studied by sum-frequency vibrational spectroscopy
Sum frequency vibrational spectroscopy (SFVS) was used to study the structure of water/{alpha}- Al{sub 2}O{sub 3} (1{bar 1}02 ) interfaces at different pH values. The OH stretch spectra are dominated by interfacial water contributions at lower frequencies, and by bonded hydroxyls on the Al{sub 2}O{sub 3} surface at higher frequencies. Protonation and deprotonation of various oxide functional groups at the {alpha}-Al{sub 2}O{sub 3} surface as pH varies can be monitored quantitatively by changes of the spectrum, allowing their pK reaction values can be estimated. The point of zero charge of the interface is found to be at pH ~ 6.7.

Effect of process variables on the quality attributes of briquettes from wheat, oat, canola and barley
Effect of process variables on the quality attributes of briquettes from wheat, oat, canola and barley straw Jaya Shankar Tumuluru*, L. G. Tabil, Y. Song, K. L. Iroba and V. Meda Biomass is a renewable energy source and environmentally friendly substitute for fossil fuels such as coal and petroleum products. Major limitation of biomass for successful energy application is its low bulk density, which makes it very difficult and costly to transport and handle. To overcome this limitation, biomass has to be densified. The commonly used technologies for densification of biomass are pelletization and briquetting. Briquetting offers many advantages at it can densify larger particles sizes of biomass at higher moisture contents. Briquetting is influenced by a number of feedstock and process variables such as moisture content, particle size distribution, and some operating variables such as temperature and densification pressure. In the present study, experiments were designed and conducted based on Box-Behnken design to produce briquettes using barley, wheat, canola and barley straws. A laboratory scale hydraulic briquette press was used for the present study. The experimental process variables and their levels used in the present study were pressure levels (7.5, 10, 12.5 MPa), three levels of temperature (90, 110, …

Effects of a Play-Based Teacher Consultation (PBTC) Program on Interpersonal Skills of Elementary School Teachers in the Classroom
The purpose of this study was to examine the effectiveness of a play-based teacher consultation (PBTC) program on individual teachers’ interpersonal classroom behaviors and teacher-child relationships. The research questions addressed the application of child-centered play therapy principles and PBTC increasing teacher responsiveness, decreasing teacher criticism, and enhancing teachers‟ perceptions of the teacher-child relationship in elementary school classrooms. Single-case design was utilized to examine eight teachers‟ perceptions over 16 weeks. The sample included 8 White female teachers from three local elementary schools. Teacher ages ranged from 28 to 59 years old. There were 5 kindergarten, 1 first grade, and 2 second grade teachers. The teachers participated in one educational training session followed by play sessions with children of focus and interactive modeling sessions. Trained observers, blind to the study’s purpose, utilized the Interaction Analysis System in classroom observations of the teachers, three times per week, to examine teachers’ interpersonal skills. Additionally, the teachers completed the Student Teacher Relationship Scale for the children of focus before and after the play session phase to examine change in the teacher-child relationship. Visual analysis of the data indicated the PBTC’s overall positive impact. 5 out of 8 teachers demonstrated increases in teacher responding scores at …

The Effects of a Self-Monitoring Procedure on Sustainable Behavior
Self-monitoring procedures are commonly used to assess environmentally sustainable behavior. The current experiment evaluated the effects of a self-monitoring procedure on two sustainable behaviors within a university office. A senior assistant was asked to report on light usage and energy-saver use on the copier in an office break room. Her reports were then compared with independent observations. Results showed that her reports were highly correspondent with independent observations although no change in target behaviors occurred. Changes in behavior occurred when she was asked to engage in the target behaviors. Results suggest that although self-monitoring procedures can correctly assess sustainable behaviors, they may not be suitable for behavior change.

The Effects of Capturing and Searching on the Acquisition of a Simple Arm Position
The present experiment compared two methods of training a simple arm position using auditory feedback: capture and search. The participants were four right-handed female college students. During capture, auditory feedback was delivered by the experimenter after the participant moved along a single axis into the target position. During search, auditory feedback was produced by the computer after the participant left clicked a mouse inside the target location. The results of a multi-element design showed that participants performed more accurately during capture training than search training. Pre-training and post-training probes, during which no auditory feedback was provided, showed similar fluctuations in accuracy across probe types. A retention check, performed seven days after the final training session, showed higher accuracy scores for search than capture, across all four participants. These findings suggest that TAGteach should incorporate an approach similar to search training to improve training outcomes.

Effects of CFT Legumine™ Rotenone on Macroinvertebrates in Four Drainages of Montana and New Mexico
Rotenone is considered essential in the restoration of native fish populations; however, the technique is contentious and criticized, specifically concerning impacts to invertebrates. Knowledge of effects to non-target organisms is important for the management and conservation of fish populations. This thesis has two general objectives: (1) demonstrate the influence CFT Legumine™ rotenone has on benthic macroinvertebrates for restoration projects in Montana and New Mexico and (2) evaluate the immediate response by means of invertebrate drift. Chapters 2 and 4 incorporate results from four different restoration projects that examine benthic macroinvertebrate response. Results indicate treatment effects are minimal for Specimen and Cherry Creek projects in Montana. New Mexico projects, Comanche and Costilla Creek suggest a greater influence. Potassium permanganate used to neutralize rotenone, influenced communities in three of the four projects. Regardless, invertebrates in all four projects recovered one-year after treatment. Chapter 3 examines macroinvertebrate drift during rotenone treatment. Results suggest a delayed response compared to previous literature. Rotenone appears to have the greatest immediate influence on the early life stages of Ephemeroptera and Plecoptera. To reduce impacts of rotenone to invertebrates, managers should apply CFT Legumine and use the minimal dosage and duration to complete the projects goal of removing …

Effects of Conditional Discrimination Training on Symmetry and Semantic Priming
Psychologists interested in the study of language find that people are faster at making decisions about words that are related than they are at making decisions about words that are not related – an effect called semantic priming. This phenomenon has largely only been document in laboratory settings using natural languages as contest and real words as stimuli. The current study explores the relation between the semantic priming effect and a laboratory procedure designed to give rise to performances that can be described as linguistic. Six adult participants learned to partition a collection of eight stimuli into two sets of four stimuli. Following this, the subjects showed the semantic priming effect within a set of stimuli but not across sets. These data suggest that it may be possible to study linguistic phenomenon in laboratory-based procedures allowing better control and the ability to ask very precise questions about linguistic functioning.

The Effects of Fines on Cooperation in a Four-Person Prisoner’s Dilemma Game
Cooperation is an important area of investigation for behavior analysis. The prisoner’s dilemma game (PDG) provides a useful scenario for studying cooperation in a behavior analytic paradigm. The PDG can be coupled with the concept of the metacontingency to investigate how various contingency arrangements support and promote cooperation in a group. Players in this experiment participated in a PDG and, in some conditions, were given the ability to fine other players but could not talk. The goal of this experiment was to investigate how players’ ability to fine one another affected the players’ patterns of cooperation, and whether fining itself was affected by the addition of a shared group consequence. The data show that participants cooperated in some conditions, but the fines did not seem to affect players’ rates of cooperation.

Electrical and Structure Properties of High-κ Barium Tantalite and Aluminum Oxide Interface with Zinc Oxide for Applications in Transparent Thin Film Transistors
ZnO has generated interest for flexible electronics/optoelectronic applications including transparent thin film transistors (TFTs). For this application, low temperature processes that simultaneously yield good electrical conductivity and optical transparency and that are compatible with flexible substrates such as plastic, are of paramount significance. Further, gate oxides are a critical component of TFTs, and must exhibit low leakage currents and self-healing breakdown in order to ensure optimal TFTs switching performance and reliability. Thus, the objective of this work was twofold: (1) develop an understanding of the processing-structure-property relationships of ZnO and high-κ BaTa2O6 and Al2O3 (2) understand the electronic defect structure of BaTa2O6 /ZnO and Al2O3/ZnO interfaces and develop insight to how such interfaces may impact the switching characteristics (speed and switching power) of TFTs featuring these materials. Of the ZnO films grown by atomic layer deposition (ALD), pulsed laser deposition (PLD) and magnetron sputtering at 100-200 °C, the latter method exhibited the best combination of n-type electrical conductivity and optical transparency. These determinations were made using a combination of photoluminescence, photoluminescence excitation, absorption edge and Hall measurements. Metal-insulator-semiconductor devices were then fabricated with sputtered ZnO and high-κ BaTa2O6 and Al2O3 and the interfaces of high-κ BaTa2O6 and Al2O3 with ZnO …

EMSL Geochemistry, Biogeochemistry and Subsurface Science-Science Theme Advisory Panel Meeting
This report covers the topics of discussion and the recommendations of the panel members. On December 8 and 9, 2010, the Geochemistry, Biogeochemistry, and Subsurface Science (GBSS) Science Theme Advisory Panel (STAP) convened for a more in-depth exploration of the five Science Theme focus areas developed at a similar meeting held in 2009. The goal for the fiscal year (FY) 2011 meeting was to identify potential topical areas for science campaigns, necessary experimental development needs, and scientific members for potential research teams. After a review of the current science in each of the five focus areas, the 2010 STAP discussions successfully led to the identification of one well focused campaign idea in pore-scale modeling and five longer-term potential research campaign ideas that would likely require additional workshops to identify specific research thrusts. These five campaign areas can be grouped into two categories: (1) the application of advanced high-resolution, high mass accuracy experimental techniques to elucidate the interplay between geochemistry and microbial communities in terrestrial ecosystems and (2) coupled computation/experimental investigations of the electron transfer reactions either between mineral surfaces and outer membranes of microbial cells or between the outer and inner membranes of microbial cells.

Environmental Litigation: Cases against EPA and Associated Costs over Time
A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency (EPA) faces numerous legal challenges as it implements the nation's environmental laws. Several statutes, such as the Clean Air and Clean Water Acts, allow citizens to file suit against EPA to challenge certain agency actions. Where EPA is named as a defendant, the Department of Justice provides EPA's legal defense. If successful, plaintiffs may be paid for certain attorney fees and costs. Payments are made from the Department of the Treasury's Judgment Fund--a permanent fund available to pay judgments against the government, as well as settlements resulting from lawsuits--or EPA's appropriations. For this review, GAO was asked to examine (1) the trends in and factors affecting environmental litigation for fiscal years 1995 through 2010 and (2) Justice's recent costs and recent plaintiff payments from the Judgment Fund and EPA. To conduct this review, GAO obtained and analyzed data from two Justice databases on cases filed under 10 key environmental statutes. To gain stakeholder views on any trends and factors that might affect them, GAO interviewed representatives of environmental and industry groups, state attorneys general, and other experts. GAO estimated the costs of …

Equivalence in Ventilation and Indoor Air Quality
We ventilate buildings to provide acceptable indoor air quality (IAQ). Ventilation standards (such as American Society of Heating, Refrigerating, and Air-Conditioning Enginners [ASHRAE] Standard 62) specify minimum ventilation rates without taking into account the impact of those rates on IAQ. Innovative ventilation management is often a desirable element of reducing energy consumption or improving IAQ or comfort. Variable ventilation is one innovative strategy. To use variable ventilation in a way that meets standards, it is necessary to have a method for determining equivalence in terms of either ventilation or indoor air quality. This study develops methods to calculate either equivalent ventilation or equivalent IAQ. We demonstrate that equivalent ventilation can be used as the basis for dynamic ventilation control, reducing peak load and infiltration of outdoor contaminants. We also show that equivalent IAQ could allow some contaminants to exceed current standards if other contaminants are more stringently controlled.

An Essential Academic Program: A Case Study of the General Studies Program at Louisiana State University in Shreveport
The purpose of this study was to provide a historical overview of the development of the General Studies (GS) program at LSU Shreveport from its inception in 1967 until 2007. Sources of data were primary, secondary, and archival documents, student information accessed through the university mainframe, alumni information obtained from a university-sponsored directory, and an interview with the former vice-chancellor of academic affairs. All data were analyzed and placed in a chronological framework. The resulting framework consisted of dividing the 40 years of program existence into four ten-year periods. The study was limited in scope to the GS program at LSU Shreveport and did not seek to compare this program with other programs offered at the university or other GS programs in the state. The study results identified several key social, economic, and political factors that influenced the program’s development. Political factors included the change from a two-year to a four-year institution, the Statewide Review Committee recommendations of 1983, the dissolving of the College of General Studies in 1984, and the accountability movement of the 1990s. Key social factors discovered were the Civil Rights and Women’s Movements of the 1960s,and progressive, life adjustment, and humanistic educational philosophies. Economic factors revealed …
