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 …

Managing Data-Driven Change: A Model Of Unintended Deviation, Sang-Mun Ray Cho

UNLV Theses, Dissertations, Professional Papers, and Capstones

Data-driven change in hospitality gaming is desirable because of the opportunities to leverage untapped sources of rich and abundant marketing data. However, change has been difficult to implement as indicated by a lack of widespread adoption. Some have attributed these difficulties to cultural, structural, and other generic factors but these explanations fail to explain the root dynamics of data-driven change.

In this dissertation, it is theorized that data-driven change requires a particular form of social interaction, which are called analytical bonds (AB). The suggestion was that there is a sender of an analytic deliverable and a receiver that makes a …

Disastrous Voting, Moritz Peter Rissmann

UNLV Theses, Dissertations, Professional Papers, and Capstones

The central question of this study is ’Is there an observable general trend of electorates punishing incumbents for natural disasters across countries and elections?’ Many scholars have argued for the existence of such behavior, yet the empirical evidence rests mostly on single-country and even single-election studies. I look for a generalizable trend in two original data sets with country-election and country-constituency-election as the unit of analysis respectively. I test the punishment hypothesis by correlating the occurrence of natural disasters to the performance of incumbent parties in national lower house elections. Furthermore, I propose that the effect of natural disasters on …

This paper presents two cases that demonstrate the design and implementation of using web videoconference for synchronous assessment in an educational research methods online course and an instructional video production online course. The purpose of the two cases was to explore whether or with what methods student online learning could be improved through synchronous assessment. Case outcomes were analyzed with nonparametric …

The Evolution Of Computational Propaganda: Trends, Threats, And Implications Now And In The Future, Holly Schnader

Senior Honors Projects, 2010-2019

Computational propaganda involves the use of selected narratives, social networks, and complex algorithms in order to develop and conduct influence operations (Woolley and Howard, 2017). In recent years the use of computational propaganda as an arm of cyberwarfare has increased in frequency. I aim to explore this topic to further understand the underlying forces behind the implementation of this tactic and then conduct a futures analysis to best determine how this topic will change over time. Additionally, I hope to gain insights on the implications of the current and potential future trends that computational propaganda has.

My preliminary assessment shows …

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 …

Watch & Learn - A Teacher's Guidebook For Film-Based Esl Course, Xiaoxue Zhu

Master's Projects and Capstones

Educators in the 21st century are continuously discovering more engaging teaching tools to facilitate language learners. In today's increasingly developing visual world, film stands out from other traditional materials for its unique features, such as the visuality and authenticity. With appropriately designed activities, film could be a valuable resource in teaching English as a second language (TESOL) setting, and also a perfect tool for inspiring cross-cultural communication and promoting critical thinking skills.

However, research has shown that ESL teachers feel reluctant to use film as a significant component in their classrooms even though they have recognized and affirmed the benefit …

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 …

Universities In Imperial Austria, 1848–1918: A Social History Of A Multilingual Space, Jan University Surman

Purdue University Press Books

Combining history of science and a history of universities with the new imperial history, Universities in Imperial Austria 1848–1918: A Social History of a Multilingual Space by Jan Surman analyzes the practice of scholarly migration and its lasting influence on the intellectual output in the Austrian part of the Habsburg Empire.

The Habsburg Empire and its successor states were home to developments that shaped Central Europe's scholarship well into the twentieth century. Universities became centers of both state- and nation-building, as well as of confessional resistance, placing scholars if not in conflict, then certainly at odds with the neutral international …

Literature In The World: A Critical Discourse Study Of World Literature Pedagogy, Elisa Cogbill-Seiders

UNLV Theses, Dissertations, Professional Papers, and Capstones

“Literature in the World” is a critical discourse analysis of world literature pedagogy in U.S. higher education. It investigates the ways discourse communities in higher education produce and shape the field of world literature. The dissertation begins by establishing and analyzing the generic conventions of university mission statements, finding they are primarily dominated by discourse on global learning. It follows with an analysis of world literature course descriptions from the same schools. World literature course descriptions alternatively replicate, resist, or subvert global learning discourses. The last chapter uses findings from the first two chapters to trace how university and instructor …

Brand Loyalty In The Cruise Sector: Age Cohorts, Gender, And Travel Attributes As Key Moderators For Relationship Marketing Theory, Stephen Wen-Hung Wang, Maxwell Kuo-Hsuan Hsu, Angeline Close Scheinbaum, Feng-Ming Tsai

Journal of Marine Science and Technology–Taiwan

Testing established theory in relationship marketing, we examine the impact of customer relationship management on customer satisfaction and brand loyalty in the context of the cruise industry. Individual differences such as age cohort (e.g., millennials, Gen X, baby boomers), gender, and consumers’ desired travel attributes are examined as moderators. Cruise vacation consumers at an international cruise harbor were approached to complete an in-person survey (n = 226). Empirical findings support extant theory in relationship marketing in that consumers’ perception of relationship investment raises satisfaction and, in turn, brand loyalty. Notably, when customer relationship investment is degenerated into a second order …

Internet addiction (IA) is classified as a compulsive-impulsive behavior disorder involving excessive use of the internet, withdrawal, tolerance, and negative repercussions (Block, 2007). Internet usage is becoming more widespread across all industrialized people, and younger people are using the internet more and more as it becomes more ubiquitous (Rideout, Foehr, & Roberts, 2010). The purpose of the current study is to investigate internet usage habits, sleep disturbance, and IA as it appeared in a national United States sample, and a sample seeking clinical psychological help in the Southwestern United States. The results of the current study suggested that IA predicted …

Establishment Of Turfgrass From Seed And Sod In Sand Based Systems Combining Sprinkler And Subsurface Drip Irrigation Systems, Roshaan Ahmed Khan Niazi

Electronic Theses and Dissertations

The establishment of turfgrass using subsurface drip irrigation (SDI) in sand based media has limited success. However, it is unknown if starting with overhead (sprinkler) irrigation and transitioning to SDI can enhance turfgrass establishment. Two experiments were conducted at Stephen F. Austin State University (SFASU) to investigate the establishment of “L-93” creeping bentgrass (Agrostis stolonifera) from seed and “TifEagle” ultra dwarf hybrid bermudagrass (Cynodon dactylon x Cynodon transvaalensis) from sod using sand based media. Each experiment consisted of two trials conducted in summer 2017 and spring 2018. Both creeping bentgrass trials and the spring ultra dwarf …

Employee Perceptions Of Organizational Corporate Responsibility And Their Effect On Employee Organizational Commitment, Lisa R. Davis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The debate over whether organizations play a part in society beyond economic profit has been a major focus of research in corporate social responsibility (CSR). These debates have been mainly looked at from the macro (societal) or the meso (institutional) level. Very little research has been done on the role of the firm and looking at CSR from the micro (individual) level. Questions regarding the role of work for employees, securing economic benefits or making a difference in the world, would vary greatly depending on the individual and the importance they place on these areas in their own lives. Scholars …

A Distributed Real-Time Short-Term Solar Irradiation Forecasting Network For Photovoltaic Systems, Michael Adelbert Gacusan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Solar irradiation forecasting is essential for PV connected electrical grids to maintain reliability, stability, and effective matching of real-time demand to power distribution. This research paper develops and evaluates proposed forecasting methods using wireless sensor networks. Each node of the network is capable of monitoring illuminance data and communicate it through RF and/or WiFi. The nodes are calibrated with respect to irradiance data from an industry-standard pyranometer. Power consumption of each node type is also collected at different operating states. The proposed sensor network can estimate a cloud motion vector or a cloud shadow’s speed and direction from the data …

Corporate Social Responsibility And Consumer Purchase Behavior: The Moderating Role Of Self-Presentation, Mandy May Walsh

UNLV Theses, Dissertations, Professional Papers, and Capstones

In recent years, companies have experienced increasing pressure to integrate corporate social responsibility (CSR) into their organizational structure. The relationship between a company's investment in CSR and overall revenue, however, is still under debate in the current literature as research has focused on correlations and consumer purchase intentions (e.g., Auger, Burke, Devinney, & Louviere, 2003; Dutta & Singh, 2013; Klein & Dawar, 2004; Maignan, 2001; Mohr & Webb 2005; Mohr, Webb, & Harris, 2001; Nanda, 2015; Wigley, 2008). Findings from previous studies have not yet assessed actual purchase behavior or potential moderating variables impacting this relationship. Therefore, this dissertation examined …

Investigating Cyanobacteria Metabolism And Channeling-Based Regulations Via Isotopic Nonstationary Labeling And Metabolomic Analyses, Mary Helen Abernathy

McKelvey School of Engineering Graduate Student Theses & Dissertations

Cyanobacteria have the potential to be low-cost and sustainable cell factories for bio-products; however, many challenges face cyanobacteria as biorefineries. This dissertation seeks to advance non-model photosynthetic organisms for biotechnology applications by characterizing central carbon metabolism and its regulations. Cyanobacteria phenotypes for bio-production are examined and their intracellular metabolism is quantified. Using isotopic labeling experiments, phenotypic relationships between biomass composition, central carbon fluxes, and metabolite pool sizes are investigated. Metabolic analyses of cyanobacteria led to new investigations of flux regulation mechanisms via protein spatial organizations or metabolite channeling. Metabolite channeling is further explored as a hypothesis to explain enigmatic labeling …

Tall Tales Of Danger And Security: How A Critical Human Security Approach Can Address Major Contradictions Revealed Through A Critical Narrative Analysis Of Dominant U.S. Security Strategies, Stephen Schneider

Master's Theses

Over many generations, humans have developed many perspectives and practices regarding the best ways to recognize and address what they perceive to be dangerous. Stories are used to help shape and narrate perceptions about the world, and they serve to pass on vital information that impacts how a society responds to threats and vulnerabilities. These narratives of danger and security are subjective to the experiences and political intentions of society, and therefore in many ways are partial and biased in their assessments and policies. This results in flawed security practices that may actually exacerbate threats or create new insecurities. What …

Syntheses Of A Tin (Iv) Meso-Tetra(4-Pyridyl) Porphyrin Dichloride-Tetrachlorobis (Bipy)2 Ruthenium (Ii) Complex And Studies Of Photophysical Properties Of 1-Nitropyrene, Phillip Sharp

Electronic Theses and Dissertations

Development of a photosensitizer that can work in both aerobic and anaerobic environments would increase the robustness of the cancer treatment known as photodynamic therapy. The development of a photosensitizer was first attempted by synthesizing a tin (IV) meso-tetra (4-pyridyl) porphyrin dichloride-tetrachlorobis (Bipy)₂ ruthenium (II) complex. The synthesize of the tin porphyrin was done by a method from literature and had a percent error of 31.58 and 37.31 when comparing the theoretical percentages of carbon (55.39) and nitrogen (12.92) meaning that photosensitizer was not synthesized.

The second type of chromophore that was studied was 1-nitropyrene do determine if it …
