Can Coping Information Enhance The Effectiveness Of A Personalized Normative Feedback Intervention, Angelee Gigi Shamaley

Open Access Theses & Dissertations

In reaction to the national health objective of reducing the proportion of college students engaging in heavy at-risk drinking, the addition of a stress and coping component to a Personalized Normative Feedback (PNF) intervention was examined. Approximately 501 college students at the University of Texas at El Paso were recruited to participate during the spring, summer, and fall 2011 semesters. The purpose of the study was to investigate if the addition of a stress and coping component to a standard PNF intervention would have a stronger impact on reducing alcohol-related problems and consumption than using standard PNF intervention. A secondary …

Heavy Metal Pollution In The Paso Del Norte Region:Historical Reconstruction And Source Interpretation, Eugenia G. Shekhter

Open Access Theses & Dissertations

A unique and complex situation of heavy metal pollution arose in the El Paso del Norte region, one of the largest and oldest metropolitan areas on the US-Mexican border. This region with its complex topography is home to more than 2.2 million people sharing the same environment. Although many studies have been conducted in the region to identify the sources of environmental contamination, the cumulative history of heavy metal pollution is still incomplete. In order to identify the patterns of heavy metal dispersion and to test the hypothesis that the American Smelting and Refining Company (ASARCO) was a considerable contributor …

Individual Predictors Of Hindsight Bias: A Longitudinal Study, Sonya M. Stokes

Open Access Theses & Dissertations

The hindsight bias, a person's tendency to overestimate their ability to predict the outcome of an event after the fact, is a phenomenon present in nearly every area of our lives (Arkes, Faust, Guilmette & Hart, 1988). The bias can be mitigated by factors such as analytical and deep thought regarding an outcome and increased expertise (Gray et al., 2007; Knoll, 2009; Arkes et al., 1988). In this study, we examined the growth of hindsight bias over 4 time points using a within-subjects memory model. For our analysis, we quantified hindsight bias in two ways: the number of "flips" a …

A Novel Fkbp52/Β-Catenin Complex Specifically Regulates Androgen Receptor Activity, Cheryl Lynne Storer

Open Access Theses & Dissertations

The androgen receptor complex plays an essential role in prostate cancer progression due to exploitation of the androgen receptor (AR) as a transcription factor. The final stage of the receptor complex consists of a dimerized receptor, a dimeric heat shock protein (Hsp90), the cochaperone p23, and an immunophilin. Hormone-dependent prostate cancer progresses due to key interactions between the androgen receptor complex and its ligand α dihydrotestosterone (DHT). While current treatments focus on blocking the androgen receptor-ligand interactions, these therapies are no longer effective in advanced stage, hormone-refractory prostate cancer (HRPC).

Therefore, we have been interested in targeting other members of …

Development Of Demand Forecasting Model For Transatlantic Air Transportation, Katerina Strelcova

Open Access Theses & Dissertations

This thesis describes the airline planning process, analyzes the demand of the busiest transatlantic routes and establishes a methodology on how to plan new transatlantic routes from Europe to United States of America with Prague Airport as a hub, or secondary airport for these flights. A few of the most used airports in Europe are chosen and flight data in 2011 from these airports to the United States was analyzed. In addition, demographic, traffic and socioeconomic data of selected airports is collected. A demand forecasting model is then developed in steps using correlation analysis, multiple linear regression analysis and doubly …

Textbooks, Teachers, And Compromise: The Political Work Of Freedmen Education, Ashley Marie Swarthout

Open Access Theses & Dissertations

After the end of the Civil War, Northerners flooded into the South in order to participate in the education of freedmen. While many, perhaps most, of the individuals who worked in freedmen education had the best interests of the freedmen in mind, freedmen education in of itself was inherently political; therefore, all contributors to freedmen education were also sponsors of Southern Reconstruction politics. It is my argument that the aid organizations (particularly the American Missionary Association and the American Freedmen's Union Commission), the writers and printers of freedmen-specific textbooks (the American Tract Society and Lydia Maria Child), and the teachers …

Purification Of Sodium Sulfate By Crystallization, Perla Teresita Torres

Open Access Theses & Dissertations

Sodium sulfate can be recovered from a dilute solution by concentrating it by conventional water treatment techniques like reverse osmosis and electrodialysis; however, those processes also concentrate impurities like arsenic. The sodium sulfate would have commercial use if it can be recovered in an arsenic-free form. This study demonstrated that sodium sulfate could be separated from impurities using slow cooling crystallization in a novel apparatus developed and designed during the experimentation. This device is called a heat exchanger crystallizer and allows slow cooling crystallization in order to grow pure crystals of sodium sulfate decahydrate. Crystals grown in the heat exchanger …

Evaluation Of Emission Control Strategies To Reduce Ozone Pollution In The Paso Del Norte Region Using A Photochemical Air Quality Modeling System, Victor Hugo Valenzuela

Open Access Theses & Dissertations

Air pollution emissions control strategies to reduce ozone precursor pollutants are analyzed by applying a photochemical modeling system. Simulations of air quality conditions during an ozone episode which occurred in June, 2006 are undertaken by increasing or reducing area source emissions in Ciudad Juárez, Chihuahua, Mexico.

Two air pollutants are primary drivers in the formation of tropospheric ozone. Oxides of nitrogen (NOx) and volatile organic compounds (VOC) undergo multiple chemical reactions under favorable meteorological conditions to form ozone, which is a secondary pollutant that irritates respiratory systems in sensitive individuals especially the elderly and young children.

Structure And Electronic Properties Of Pure And Nitrogen Doped Nanocrystalline Tungsten Oxide Thin Films, Vemnkata Rama Sesha Ravi Kumar Vemuri

Open Access Theses & Dissertations

Tungsten oxide (WO₃) is a multifunctional material which has applications in electronics, sensors, optoelectronics, and energy-related technologies. Recently, electronic structure modification of WO₃ to design novel photocatalysts has garnered significant attention. However, a fundamental understanding of nitrogen induced changes in the structure, morphology, surface/interface chemistry, and electronic properties of WO₃ is a prerequisite to producing materials with the desired functionality and performance. Also, understanding the effect of thermodynamic and processing variables is highly desirable in order to derive the structure-property relationships in the W-O/W-O-N material system. The present work was, therefore, focused on studying the effects …

Bilingual Adult Nonword Repetition Performance Patterns In English And Spanish, Gabriela Villaneda

Open Access Theses & Dissertations

Nonword repetition (NWR) is known to assess phonological working memory. During NWR, the individual listens to made-up words and repeats them back. This study evaluated NWR performance patterns, and the relationship between NWR and language recall tasks among forty English and Spanish bilingual adults. Bilingual adults' ages ranged from 18-67 years. Four language recall tasks were administered, including NWR tasks (assessed by PPC), language questionnaire to assess participants' language usage in English and Spanish, sentence repetition task (assessed by raw score), and a story retell (assessed by NDW). All recall measures were administered in a counterbalanced manner across English and …

International Polar Year (Ipy) Back To The Future (Btf): Changes In Arctic Ecosystem Structure Over Decadal Times Scales, Sandra Villarreal

Open Access Theses & Dissertations

Arctic vegetation communities are responding to climate warming through shifts in species composition and diversity but most observations have been made over relatively short time frames, and/or in association with experimental manipulations. Because vegetation plays a key role in regulating ecosystem productivity, nutrient cycling, surface energy budgets, and trophic interactions in the Arctic, there is a need to better understand shifts in tundra vegetation communities over decadal time scales. Understanding these shifts and their impact on ecosystem structure and function in the Arctic has important implications for predicting the future state of both the Arctic and the Earth System. Long …

Investigation Into The Operation And Safety Of Freeway Auxiliary Lanes: Towards Uniform Design Guidelines, Yubian Wang

Open Access Theses & Dissertations

Freeways operate closest to the purest form of uninterrupted traffic flow. There is no constant interruption to traffic flow (such as stop sign and traffic signal), and access is limited to ramp locations. Therefore, at freeways, bottlenecks, if exist, are usually caused by merging and diverging traffic at ramp locations. Bottleneck removal at freeway ramp areas can reduce average freeway commuter delay. Currently, engineers may add auxiliary lanes at ramp areas to mitigate or remove bottlenecks.

Printable Biodegradable Hydrogel For Skin Wound Dressing Using Inkjet Printing Technology, Maria G. Yanez

Open Access Theses & Dissertations

Chronic wounds are becoming more frequent. Foot ulcers affect approximately 10% - 15% of patients with diabetes throughout their lifetimes, and by 2025, it is estimated the prevalence of diabetes will be 250 million people in the worldwide. There is increased potential for patients with peripheral neuropathy and peripheral vascular disease to suffer more foot injuries. These conditions reduce the normal pain sensations and healing of minor traumas, allowing the development of chronic non-healing ulcers, often preceding lower-extremity amputation. These types of wounds are very difficult to treat and sometimes take months or even years to heal because of many …

Finding Room For Everyone: Libraries Confront Social Exclusion, Jen Hoyer

Publications and Research

Communities that are working to combat exclusion have greater potential for success if they enlist the support of public libraries, which are in many ways ideally situated to welcome marginalized populations and provide programs and services that combat social exclusion. This chapter explains how this adaptability in response to social problems fits with the mandate of public libraries; examines why and how libraries should confront social exclusion; and looks at the Atwater Library and Computer Centre (ALCC) in Westmount, Québec, as an illustration of how this has been successfully accomplished.

Blogging Chronic Illness And Negotiating Patient-Hood: Online Narratives Of Women With Ms, Collette Sosnowy

Dissertations, Theses, and Capstone Projects

Personal narratives about women's everyday lives with chronic illness are mapped onto the landscape of social media through blogging. Social media is facilitating an already-existing shift in patients' roles as they are increasingly enabled and expected to self-educate themselves about their illness, collaborate with providers, self-manage their care, and engage in health activism. The health care industry has seized on the widespread use of social media to bolster rhetoric that the accelerated knowledge development made possible through social media has the potential to revolutionize the practice of medicine. Critics, however, argue that responsibility and activism via digital technologies has become …

Prelude To Seven Slots: Filling And Subsequent Modification Of Seven Broad Canyons In The Navajo Sandstone, South-Central Utah, David B. Loope, Ronald J. Goble, Joel P. L. Johnson

Department of Earth and Atmospheric Sciences: Faculty Publications

Within a four square kilometer portion of Grand Staircase-Escalante National Monument, seven distinct slot canyons cut the Jurassic Navajo Sandstone. Four of the slots developed along separate reaches of a trunk stream (Dry Fork of Coyote Gulch), and three (including canyons locally known as “Peekaboo” and “Spooky”) are at the distal ends of south-flowing tributary drainages. All these slot canyons are examples of epigenetic gorges—bedrock channel reaches shifted laterally from previous reach locations. The previous channels became filled with alluvium, allowing active channels to shift laterally in places and to subsequently re-incise through bedrock elsewhere. New evidence, based on optically …

Challenging The State Of The Art In Post-Introductory Statistics: Preparation, Concepts, And Pedagogy, Nathan L. Tintle, Beth Chance, George Cobb, Allan Rossman, Soma Roy, Todd Swanson, Jill Vanderstoep

Faculty Work Comprehensive List

The demands for a statistically literate society are increasing, and the introductory statistics course ("Stat 101") remains the primary venue for learning statistics for the majority of high school and undergraduate students. After three decades of very fruitful activity in the areas of pedagogy and assessment, but with comparatively little pressure for rethinking the content of this course, the statistics education community has recently turned its attention to use of randomization-based methods to illustrate core concepts of statistical inference. This new focus not only presents an opportunity to address documented shortcomings in the standard Stat 101 course (for example, improving …

The Rise Of Disyllables In Old Chinese: The Role Of Lianmian Words, Jian Li

Dissertations, Theses, and Capstone Projects

The history of Chinese language is characterized by a clear shift from monosyllabic to disyllabic words (Wang 1980). This dissertation aims to provide a new diachronic explanation for the rise of disyllables in the history of Chinese and to demonstrate its significance for Modern Chinese prosody and lexicalization.

A corpus of 300 Lianmian words in Old Chinese was compiled, including 96 Shuāngshēng words, 172 Diéyùn words and 32 Splitting-sound words. This study builds on previous morphological and phonological research on disyllables in Chinese and looks closely at detailed aspects of Old Chinese sound patterns and their evolution. Based on the …

Reduction Of Observable Robbery And Larceny-Theft In The Twelve Largest Cities In The United States From 1980 To 2009, Andrew J. Costello

Dissertations, Theses, and Capstone Projects

The reduction in crime rates that occurred in large cities across the United States (US) over the course of the past two decades has been the subject of much speculation and research. However, there have been no definitive empirical studies that conclusively determine the causes for this phenomenon. The goal of this study is to identify the impact of certain factors to the reduction of crime in large US cities that occurred over the past two decades by examining data over a thirty-year period (1980-2009). The identification of contributing factors may allow government officials, both on a local and national …

Understanding And Interpreting Japanese Np1 Wa Np2 Da Sentences: Mechanism And Contextual Factors, Megumi Yoshida

Dissertations, Theses, and Capstone Projects

This dissertation investigates the contextual factors that affect the understanding and interpretation of one Japanese topicalized construction, NP1 wa NP2 da sentences, by native speakers of Japanese. The construction allows two possibilities in the relation between the NP1 and the NP2. When the two NPs are not syntactically connected (Type I), the sentence is generally vague, and a particular context is required to specify the meaning. When they are syntactically connected (Type II), they can refer to a semantically identical referent, and the sentence is naturally interpreted as an identity sentence. The aim of the study is to examine how …

School Wide Positive Behavioral And Intervention Supports : The Effectiveness Of Tier 1 Strategies, Gregory James Halsor

Dissertations and Theses @ UNI

This literature review critically examines the effectiveness of Tier 1 Positive Behavioral and Intervention Supports (SWPBIS). Managing problem behavior in the school setting has been a major focus of educators, with the goal of lowering classroom disruptions and increasing the effectiveness of learning.

Over the years, school wide behavior management programs have not been consistent or widespread leading educators to identify disruptive behavior as a primary concern in their classrooms. SWPBIS emphasizes the integration of measurable outcomes, data-based decision making, and evidence based interventions. Research on the implementation of SWPBIS in schools has displayed positive effects related to decreasing the …

Comparing Second Grade Students' Creative And Content Knowledge Performance On Figural Transformation Activities Introduced In A Standard Or Enhanced Manner With Nutrition Content Knowledge Taught Through Factual Or Fantasy Reading, Angela Naomi Webb

Dissertations and Theses @ UNI

Creativity and problem solving are skills students need for success in the 21st century. With the increasing pressures of achieving higher student scores in emphasized content areas, teachers' instruction in science, social studies, music and art has been reduced to provide additional time for teaching reading and mathematics.These lost instructional areas often allowed students to express themselves creatively. Therefore, educators need to find a way to incorporate creativity into content areas like reading and mathematics.

This 16 week repeated measures study examined second grade students' academic and creative performance on figural transformation drawings during an extended reading-science-creativity integrated unit. A …
