The Impacts Of Acculturation Patterns And Processes On Immigrants' Success In Higher Education: A Multiple Case Study Of 1.25-Generation Third-Wave Iranian Immigrants To The United States, Fereshteh Rezaeian

UNLV Theses, Dissertations, Professional Papers, and Capstones

The United States of America is inherently a pluralistic society composed of various groups of immigrants. As scholars (Camarota & Zeigler, 2016; Gibson, 1998) state, the number of immigrant children accounts for 20% of the total number of school-age children. Despite all attempts to provide the best education to such a great number of immigrant students, the achievement gap between immigrant and non-immigrant students still exists (Baum & Flores, 2011; Rong & Preissle, 2008). Some scholars (e.g., Ramos & Sanchez, 1995) have proposed that the key factor for immigrants to be successful in the United States is to adapt to …

Fluid Structure Interaction Study Of The Obstructive Sleep Apnea And Surgical Treatment Using Suture-Patch Device On The Patient’S Tongue, Yang Liu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Up to 14% of the U.S. population is estimated to have obstructive sleep apnea (OSA) related to obesity, and there is increased incidence occurring worldwide. While treatment with continuous positive airway pressure (CPAP) resolves airway obstruction, patient compliance is relatively low. Alternative interventions are available to treat OSA patients; however, their outcomes have had variable results. For example, current technologies have demonstrated an inability to define and treat the specific anatomical site(s) causing the obstruction, resulting in suboptimal modifications of the airway and poor control of OSA.

In the current study, a three-dimensional (3-D) fluid-structure interaction (FSI) numerical simulation has …

The Roles Of Biophilic Attitudes And Auditory Stimuli Within Attention Restoration Theory, Jason B. Boggs

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attention Restoration Theory indicates that interacting with nature allows one’s fatigued, directed attention to be restored. This effect has been documented and produced through directed interaction with nature, such as a walk in the park, as well as through indirect interactions (e.g., photographs). The current dissertation was designed to: 1) investigate whether and how biophilic attitudes affect the attention-restoring effects incurred from interactions with nature, and 2) extend the research on ART by assessing the impact of nature-related audio stimuli. A total of 184 participants completed an assessment of biophilic attitudes, engaged in attention fatiguing exercises, and participated in one …

Identifying Youth At Risk For Problematic Absenteeism Using Nonparametric Modeling: The Impact Of Youth Psychopathology And Family Environment Risk Factors, Mirae Fornander

UNLV Theses, Dissertations, Professional Papers, and Capstones

The best cutoff to differentiate problematic school absenteeism from nonproblematic school absenteeism has yet to be identified in the literature (Lyon & Cotler, 2007). Contemporary classification systems, including Multi-Tiered Systems of Support (MTSS), depend upon cutoffs to clearly define the various tiers (Jimerson, Burns, & VanDerHeyden, 2016). The current study aimed to inform the MTSS approach while also contributing to early identification, assessment, and intervention methods for those youth and families at the highest risk of problematic school absenteeism and its negative consequences. The current study identified subgroups of youth at the highest risk of problematic absenteeism, defined as equal …

Influencing Hawai‘I Hotel Patrons To Use Reef-Safe Sunscreens, Rochelle Good

UNLV Theses, Dissertations, Professional Papers, and Capstones

The health of Hawaiian coral reefs is threatened by pollution from common sunscreen ingredients such as oxybenzone. Hawai‘i hotel patrons using sunscreens with harmful ingredients contaminate coral reefs when these products wash off while swimming or bathing. Reef-safe sunscreens are alternative sunscreens that provide effective sun protection while averting damage to coral reefs. The purpose of this research was to determine the dominant factors leading to the pro-environmental behavior of using reef-safe sunscreen and identify practices that Hawai‘i hotel operators could implement to influence patrons to engage in this behavior. This research applied an integrative conceptual framework to model pro-environmental …

Optimization Of Useful Hard X-Ray Photochemistry, David Lewis Goldberger

UNLV Theses, Dissertations, Professional Papers, and Capstones

X-ray induced damage is generally considered a nuisance, but in the field of Useful Hard X-ray Photochemistry we harness the highly ionizing and penetrating properties of hard X-rays (> 7 keV) to initiate novel photochemical decomposition and synthesis at ambient and extreme conditions. Preliminary experiments suggest that the energy of irradiating photons and the sample pressure play roles in determining the nature of X-ray induced damage. Here, we present the X-ray energy dependence of damage induced in strontium oxalate, strontium nitrate, and barium nitrate, as well as the pressure dependence of X-ray induced damage of strontium oxalate. Our results indicate …

A Qualitative Multiple Case Study Of The Transition Experiences Of Parents And Service Providers Of Individuals With Intellectual/Developmental Disabilities (Idd) In A Postsecondary Educational Program, Rebecca S. Rogers

Theorizing Development Of Parasocial Engagement, Riva Tukachinsky, Gayle S. Stever

Communication Faculty Articles and Research

The article proposes a theoretical model of the development of parasocial relationships (PSRs) building on Knapp’s model of relationship development. Through synthesis of research across disciplines, the model conceptualizes the relational goals and parasocial interactions (PSIs) specific to the PSR. The model identifies variables that predict engagement at that level, describes the stage’s outcomes/effects, and considers the utility of existing measures to assess these stages. The conceptualization of PSRs as a dynamic process rather than intensity of a monolithic experience offers new directions worthy of empirical examination.

A Pilot Study On Real-Time Monitoring Of Heart Rate And Movement Speed In Middle-Distance Race Of Physical Education Classes, Daqing Zhu, Xingui Zhang, Lanying Fu, Peiyong Wang, Shaohong Zhai

Journal of Educational Technology Development and Exchange (JETDE)

In Chinese universities, students need to participate in the middle-distance-race. Normally, female students are required to participate in the race of 800 meters, while male students are required to participate in the race of 1000 meters. However, it is difficult for teachers to grasp the real time information of students during the race. And there is a lack of timely communications between the teachers and students. Focusing on this issue, this study, with the use of POLAR heart rate sensor and other modern information technologies, expands the original function of the sensor to achieve a concurrent operation of detecting heart …

Soldiers’ Motivations To Fight In World War Ii: The United States Army And The German Wehrmacht In The European Theatre, Anthony E. Hart

History & Classics Undergraduate Theses

The European theatre of the Second World War has often been perceived as an ideological conflict driven by nationalism and patriotism. Ideology, patriotism, and nationalism may have been the motivations of leaders and citizens on the home front in Germany and the United States, but what about the men in the American and German armies fighting on the front lines? They may have been similarly motivated prior to their deployment, but what motivated soldiers in the U.S. Army and the Wehrmacht to continue fighting as the war dragged on and as they endured the horrors of combat? Were the motivational …

Serum Nutrient Levels And Aging Effects On Periodontitis, Jeffrey L Ebersole, Joshua Lambert, Heather Bush, Pinar Emecen Huja, Arpita Basu

Biostatistics Faculty Publications

Periodontal disease damages tissues as a result of dysregulated host responses against the chronic bacterial biofilm insult and approximately 50% of US adults > 30 years old exhibit periodontitis. The association of five blood nutrients and periodontitis were evaluated due to our previous findings regarding a potential protective effect for these nutrients in periodontal disease derived from the US population sampled as part of the National Health and Nutrition Examination Survey (1999–2004). Data from over 15,000 subjects was analyzed for blood levels of cis-β-carotene, β-cryptoxanthin, folate, vitamin D, and vitamin E, linked with analysis of the presence and severity of periodontitis. …

A Force Sensor That Converts Fluorescence Signal Into Force Measurement Utilizing Short Looped Dna, Golam Mustafa, Cho-Ying Chuang, William A. Roy, Mohamed M. Farhath, Nilisha Pokhrel, Yue Ma, Kazuo Nagawawa, Edwin Antony, Matthew J. Comstock, Soumitra Basu, Hamza Balci

Biological Sciences Faculty Research and Publications

A force sensor concept is presented where fluorescence signal is converted into force information via single-molecule Förster resonance energy transfer (smFRET). The basic design of the sensor is a ~100 base pair (bp) long double stranded DNA (dsDNA) that is restricted to a looped conformation by a nucleic acid secondary structure (NAS) that bridges its ends. The looped dsDNA generates a tension across the NAS and unfolds it when the tension is high enough. The FRET efficiency between donor and acceptor (D&A) fluorophores placed across the NAS reports on its folding state. Three dsDNA constructs with different lengths were bridged …

Elevated Temperature Progressive Damage And Failure Of Duplex Stainless Steel, Darren P. Luke

Civil Engineering ETDs

Ductile failure of metals has been the focus of research efforts within academia and industry for many years since it is tremendously important for understanding the failure of structures under extreme loading conditions. However, limited research has been dedicated to elevated temperature ductile failure, which is critical for evaluating catastrophic events such as industrial, structural or shipping vessel fires. A detailed investigation was conducted on the structural response of Duplex Stainless Steel at elevated temperatures. The temperature dependence of elastic modulus, yield strength, ultimate strength, and ductility was measured up to 1000°C and a continuum damage plasticity model was developed. …

Chemically Modified Monolayer Surfaces Influence Valvular Interstitial Cell Attachment And Differentiation For Heart Valve Tissue Engineering, Matthew N. Rush

Nanoscience and Microsystems ETDs

As a cell mediated-process, valvular heart disease (VHD) results in significant morbidity and mortality world-wide. In the US alone, valvular heart disease VHD is estimated to affect 2.5% of the population with a disproportionate impact on an increasing elderly populous. It is well understood that the primary driver for valvular calcification is the differentiation of valvular interstitial cells (VICs) into an osteoblastic-like phenotype. However, the factors leading to the onset of osteoblastic-like VICs (obVICs) and resulting calcification are not fully understood and a more complete characterization of VIC differentiation and phenotypic change is required before treatment of valve disease or …

Doing Business In America: A Jewish History, Purdue University Press

The Jewish Role in American Life: An Annual Review

American and Jewish historians have long shied away from the topic of Jews and business. Avoidance patterns grew in part from old, often negative stereotypes that linked Jews with money, and the perceived ease and regularity with which they found success with money, condemning Jews for their desires for wealth and their proclivities for turning a profit. A new, dauntless generation of historians, however, realizes that Jewish business has had and continues to have a profound impact on American culture and development, and patterns of immigrant Jewish exploration of business opportunities reflect internal, communal, Jewish-cultural structures and their relationship to …
