This paper proposes that digital media has changed the way art is viewed and experienced. This investigation into technology unpacks the effect that technology has on our society. Through the process of photography and digital media, the exploration of social interactions with technology is observed. The observation that is highlighted in this artwork is multilayered, which includes the digital rituals and the acceptance of new digital social norms. In addition, an argument is made that due to this change in social acceptance to the new digital world, there seems to be a disconnect between those who are engrossed in the …

The Dominican Liberator: Father Edward Paul Doyle, O.P.’S Response To The Holocaust, Jacqueline Michels

History & Classics Undergraduate Theses

Individual survivors and witnesses to the Holocaust each remember and reflect on their experiences differently. Some are angry at the Nazis for their inhumane actions. Some are angry at God for allowing these evils to take place. Others learned from their experience. Edward Paul Doyle, O.P. was one of the latter. A Dominican Friar at Providence College, he served as an army chaplain for the United States Army in Germany during World War II. While in Germany, Father Doyle helped to liberate Nordhausen concentration camp where he witnessed the horrors of the Holocaust. Father Doyle recorded his experience and reflections …

Examining The Training Transfer Practice Of A Financial Institution: An Action Research Study, Maria Lourdes Lourdes Gutierrez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many organizations rely on training to improve the skills and knowledge of its human resources. The underlying assumption is that employees will use what they learned when they return to the workplace. Although there is evidence that learning occurred it does not always result in transfer (Mosel, 1957). Transfer is an issue of concern for training practitioners. If despite the significant investment no return is realized, then the training is not effective and the investment is wasted. This action research study was conducted in a financial institution in the Southwestern United States. The purpose of this study was to (1) …

Associations Between Opioid-Related Hospitalizations And Intravenous Drug Users, Jacklynn De Leon

UNLV Theses, Dissertations, Professional Papers, and Capstones

The opioid epidemic has led to a chain reaction of public health concerns, including an increase in heroin usage, injection drug abuse, incidence of hepatitis C virus (HCV), and HIV transmission. There have been few population-based studies investigating the clinical and socio- demographic data associated with opioid use in Nevada (Feng et al., 2016; Frank, 2000) and few studies investigating the intravenous drug user (IDU) population in Clark County. On February 2017, Clark County’s first syringe exchange program (SEP) opened its doors to the IDU population. This study provides an updated analysis of opioid-related injuries within Nevada and provides a …

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 …

Why Musical Groove Makes Us Move: An Electroencephalographic Investigation, Samantha Reina O'Connell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Moving to the groove of the music is a phenomenal and universal human behavior. Common characteristics to most dance music include a salient beat, rhythmic complexity, and a dynamic musical structure. What is unknown, however, is why music has the power to promote physical movement. Musical rhythm and motor processing are tightly linked activating brain areas important for motor preparation and execution. While studies demonstrate that the motor system is active during beat processing, it is still unclear how musical groove, a beat-influenced quality to music that makes us want to move, can engage these motor areas. Here, I performed …

Design And Analysis Of First And Second Order K-Delta-1-Sigma Modulators In Multiple Fabrication Processes, Shada Sharif

UNLV Theses, Dissertations, Professional Papers, and Capstones

Analog to digital converters (ADC) are an important category of electronic circuits that are required in order to convert real-world analog signals into the digital domain. One of the main trade-offs in ADC design is between data conversion speed and resolution. Delta Sigma ADCs are commonly used for high precision data conversion of low bandwidth signals such as those found in audio, industrial and biomedical applications. A major disadvantage of traditional Delta Sigma ADC architectures is that they have limited signal bandwidth and are not suited for high speed applications such as communication systems. The continuous time K-Delta-1-Sigma (KD1S) modulator …

Case Study: Armenian And Cuban Ethnic Interest Groups In American Foreign Policy, Harry H. Terzian

UNLV Theses, Dissertations, Professional Papers, and Capstones

Current academic research has moved away from comparative models as a mechanism by which to assess and understand socio-political as well as historical phenomena. In addition, comparative analysis when it comes to addressing ethnic lobbies is almost nonexistent within contemporary research. This work implements a comparative framework and as a result has unlocked a new approach when addressing ethnic advocacy organizations. The purpose of this research is to assess and document the history and impact of both Armenian and Cuban ethnic interest groups within the United States. Specifically, focusing upon the Armenian National Committee of America and the Cuban American …

Variable Transition Time Inverters In A Digital Delay Line With Analog Storage For Processing Fast Signals And Pulses, James Kenton Mellott

UNLV Theses, Dissertations, Professional Papers, and Capstones

As the electronics industry moves forward there is an increasing need to process information faster and more accurately. High speed signals are used in scientific instrumentation, range finding devices, radar applications, and electro-optical interfaces. High-speed state of the art analog-to-digital converters are required to process these signals in real time. High frequency signals or very fast pulses are not able to be processed accurately due to either Nyquist-rate limitations or practical power consumption limits. For applications where signals are transient in nature and design size and power consumption are major factors, the proposed Variable Fast Transient Digitizer (VFTD) will be …

The Effect Of Instructors Training On Technology Adoption, Course Design, And Student Experiences: A Multiple Case Study Of Training Based On Tpack Or Quality Matters, Yvette Aqui

UNLV Theses, Dissertations, Professional Papers, and Capstones

The use of a Learning Management System (LMS) such as Blackboard Learn (Blackboard Learn, 2009) is a ubiquitous feature of the undergraduate experience. Despite its rapid increase in popularity and student demand for anytime, anywhere access to course materials, adoption of the LMS is slow and uneven. Some instructors also do not take advantage of some of the interactive tools in the LMS because it is complex in nature or they are unaware of the pedagogical affordances of the technology.

The purpose of this study was to explore the best ways to train faculty on how to use the LMS. …

The Influence Of Opponent Strategy And Psychopathic Traits On Point Gains And Cooperation In The Iterated Prisoner’S Dilemma, Mary Baggio

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Prisoner’s Dilemma game is a paradigm used to model and measure social cooperation. Uncooperative behavior may be one manifestation of the unstable interpersonal functioning in psychopathy. I investigated the effect of opponent strategy as well as psychopathic traits of fearless dominance (FD) and impulsive antisociality (IA) on cooperation rates and total and competitive point gains in a sample of 177 undergraduates playing long, finitely iterated Prisoner’s Dilemma games against computerized opponents who varied in their interpersonal styles from very harsh to very lenient. I analyzed rates of cooperation during each game, participants’ total points gained, and the difference in …

Efficient And Practical Composition Of Lock-Free Data Structures, Neha Bajracharya

UNLV Theses, Dissertations, Professional Papers, and Capstones

A concurrent data object is lock-free if it guarantees that at least one, among all concurrent operations, finishes after a finite number of steps. In other words, a lock free technique guarantees that some thread always makes progress. Lock-free data objects offer several advantages over their blocking counterparts, such as being immune to deadlocks and priority inversion, and typically provide high scalability and performance, especially in shared memory multiprocessor architectures.

Composition of data structures is a powerful approach to combine simple data structures to create more complex ones. It works as a building block for many advanced useful data structures. …

A Phenomenological Study On The Professional Development Of African American Male Administrators At Predominately White Post-~Secondary Institutions, Arnold Shmorn Bell

UNLV Theses, Dissertations, Professional Papers, and Capstones

As of today, African Americans continue to face a daunting endeavor when seeking to become executive administrative leaders at predominately White post-secondary institutions, even though, according to Tillman (2001), “Mentoring was identified as a technique to assist the professional advancement of African American faculty. In doing so, their numbers will increase at predominantly White institutions” (p. 295). Literature steadily indicates that mentorship contributes to one’s career development in the post-secondary environment. The influential aspects of mentorship on one’s professional development is supported by numerous studies that examines mentoring relationships across various academic disciplines and businesses in corporate America (Brown, 2005). …

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 …

This dissertation study extends on current understandings of gesture and embodied interaction with the eco-social environment in second language development (SLD) while introducing new aspects of movement analysis through dynamical modeling. To understand the role of embodiment during learning activities, a second language learning task has been selected. Dyads consisting of a non-native English-speaking student and a native English-speaking tutor were video recorded during writing consultations centered on class assignments provided by the student. Cross-recurrence quantification analysis was used to measure interactional movement synchrony between the members of each dyad. Results indicate that students with varied English proficiency levels synchronize …

Mob-Ndr Kinase Signaling Components Are Required For Epithelial Tube Formation In The Drosophila Follicular Epithelium, Juan Carlos Duhart

UNLV Theses, Dissertations, Professional Papers, and Capstones

A major goal of developmental biology is to understand how a single fertilized cell can give rise to the many functional tissues and organs, of specific sizes and shapes, that make up the adult body plan. Over the last 25 years, developmental geneticists have uncovered much concerning the cell-to-cell communication systems that are necessary to build complex tissues and organs. For example, throughout development, cells communicate with their neighbors using specialized signaling molecules. These signals are instructive and provide “signal-receiving” cells with information about space and time. That is, signal-receiving cells “learn” precisely where they are located, and, how far …

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 …

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 …

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 …
