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.

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 …

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 …

UNLV Theses, Dissertations, Professional Papers, and Capstones

As we move toward energy independence and more ambitious clean energy goals, solar energy research must push the efficiency limits of traditional energy generation systems. Increases in efficiency can be achieved by increasing the hot temperature of the power cycle. Recent research demonstrates the potential for increased efficiency and a vastly smaller component size when supercritical carbon dioxide Brayton power cycles are used. Concentrated solar and nuclear heat sources are capable of achieving the high working fluid temperatures needed for significant efficiency gains. This NSF EPSCoR funded, experimental research system is designed to exploit the uniquely immense solar irradiance of …

A Qualitative Study Of School Psychologists' Perception And Interpretation Of Their Professional Identity, Elizabeth A. Sanders

UNLV Theses, Dissertations, Professional Papers, and Capstones

The primary focus or aim of this qualitative multiple-case study was to increase understanding of how experienced school psychologists define themselves as professionals within the field, taking into consideration the profession’s collective or organizational identity, the parameters established by the organization, and the actual performance of the job within the educational setting. Specifically, this study examined how the individuals’ definitions had changed over time and what lived experiences led to development and change in professional identity. Six school psychologists with 10 or more years of experience from a large urban Southwestern school district’s school psychology department were invited to participate. …

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 …

Screen Time, Sleep, And Mental Health: An Investigation Of Electronics Use And Sleep Habits, Robert Nicks

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 …

Healing Wounds Through Nutrition, Deanna Garza

Master's Projects and Capstones

Abstract

The role of nutrition in wound care is often overlooked. The main reasons why wounds fail to heal are malnutrition, infection, impaired organ function due to co-existing diseases such as diabetes, hypertension, renal disease, and peripheral vascular disease to name a few. These factors have contributed to poor patient outcomes and patient satisfaction, as well as an increase in hospital length of stay. To promote wound healing, fuel from macro and micronutrients are necessary to deliver oxygen and energy for cell regeneration. However, nurses must possess knowledge and understanding of these requirements and the effects of nutrition on wound …

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 …

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 …

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 …

Development Of The Emotional Verbal Learning Test - Spanish (Evlt-S), Davor Nicolas Zink

UNLV Theses, Dissertations, Professional Papers, and Capstones

Emotional disturbances are common features of clinical disorders and are often present in individuals who have neurodevelopmental or acquired brain disorders. The Hispanic population is the largest and fastest growing ethnic minority group in the United States (U.S.) and by 2050 is projected to be the largest. However, few instruments are available to evaluate emotional functioning in individuals who speak Spanish. Fewer still are available to assess cognitive disturbances resulting from brain dysfunction that impact emotion processing. Normal processing of emotion is critical for social functioning. In recent years it has become apparent that cognitive abilities specialized to process social …

Personality Patterns Of Students Who Make A Threat Of Targeted School Violence, Tawnya Michelle Ayim

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although school shootings date back to the 1760’s (Dixon, 2005), recent attacks at schools in our country have raised awareness of school violence. This study investigates how students from one large school district responded to the personality pattern items on the Millon Adolescent Clinical Inventory, Second Edition after having made a threat to harm another student or staff member. Personality patterns were investigated in the overall sample, as well as within groups designated to be at a Low/Moderate risk level and High/Imminent risk level following a threat assessment. The minimal Differences between the sample for the current study and the …

Conversational Movement Dynamics And Nonverbal Indicators Of Second Language Development: A Microgenetic Approach, Kristine Marie Bragg

UNLV Theses, Dissertations, Professional Papers, and Capstones

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 …

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 …

Confirmatory Factor Analysis Of Oppositional Defiant Disorder Within Clinically Referred Youth, Breanna Garcia

UNLV Theses, Dissertations, Professional Papers, and Capstones

Each new edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013) has been met with substantial criticism. Particularly, in DSM-5, two disorders were defined by very similar criteria. Oppositional defiant disorder (ODD) was defined as consisting of three dimensions - irritability, noncompliance, and spiteful/vindictive. Additionally, ODD has duration criteria that indicate its symptoms must be present for at least 6 months suggesting the presence of chronic irritability. DSM-5 also included disruptive mood dysregulation disorder (DMDD) as a disorder marked by the presence of chronic irritability in childhood and adolescence. The question of whether chronic irritability (i.e., …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The three studies that comprise this dissertation examine relations between student characteristics, motivations, metacognitive learning processes, and academic achievement. Methodologically, the dissertation demonstrated the potential of multiple types of approaches

and data resource types. By employing multiple approaches including variable-centered, person-centered, and learning analytics, researchers can understand learning processes from various angles. In addition, through this triangulation by multiple types of methodological approaches, educational theories could be more thoroughly verified and supported by various empirical findings. Multiple types of data resources are related to analytical methods.

The purpose of the first paper was to examine relations between achievement goals and …

Examining Environmental Hazards In Rental Homes And Habitability Laws In Clark County, Nevada, Jorge Luis Bertran

UNLV Theses, Dissertations, Professional Papers, and Capstones

It is well established that home conditions are linked to the health outcomes of occupants. There are over 880,000 housing units in Clark County, Nevada; nearly half of those are renter-occupied units (ROUs). Currently, there is limited research on the characteristics of environmental hazards found in Clark County ROUs and the strength of habitability statutes created to protect tenants from substandard housing. Understanding how renters in Clark County are affected by environmental hazards in ROUs and the processes by which landlords and tenants resolve grievances related to those hazards would benefit public health. It would enhance the ability to quickly …

Factors That Impact Direct Democracy And Voter Turnout: Evidence From A National Study On American Counties, Michael Joseph Biesiada

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examines factors that impact citizen initiatives and voter turnout. The dissertation contains two parts that build upon each other with fitting theoretical frameworks. The first part investigates the decision for a county government to permit citizen initiatives. This part applies new institutionalism theory as a framework to examine county governance, autonomy, and decision-making. County governments play a vital role in American politics, yet little is known about why some counties permit citizen initiatives while others do not. I address a gap in the literature that focuses on policy outcomes that vary at the county-level due to election laws. …

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 …

Understanding Adolescent Physical Activity In The Early Nutrition Transitioning Country Of Haiti, Haley V. Becker

Arts & Sciences Graduate Student Theses and Dissertations

The nutrition transition is underway in Haiti, giving rise to the dual burden of malnutrition. Physical activity (PA) plays an important role in mitigating the negative health consequences of nutrition transition and the dual burden, but heretofore this data has been unavailable for Haiti. This dissertation undertook an exploratory needs assessment providing baseline PA data for Haitian adolescents. It evaluated two different PA data collection methodologies: a cross-sectional survey adapted from the IPAQ long-form and objectively measured PA via Actigraph GT1M accelerometers. Next, it identified initial covariates of self-reported and objectively-assessed PA behaviors; data was operationalized as meeting the World …

Intersecting Variables Of Second And Foreign Language Reading: Self-Assessment And Comprehension With Adolescents And Adults Across Languages, Haley Dolosic

Arts & Sciences Graduate Student Theses and Dissertations

Today, more individuals are seeking to learn a second language (L2) or foreign language (FL) than ever before. These individuals are language learners who intend to use their growing L2 knowledge to traverse linguistic and national boundaries in order to achieve their personal and professional goals (Callahan & Gándara, 2014). To realize these goals in the digital era, L2 learners must be more prepared than ever to use their knowledge with written media, making L2 reading a central skill to successful use of their L2 knowledge. Yet, when language learners attempt to use their L2 skills in their daily lives, …

Telelactation And Breastfeeding Outcomes Among Low-Income Mothers In Mississippi: A Retrospective Cohort Study, Aaron Thomas Hunt

UNLV Theses, Dissertations, Professional Papers, and Capstones

New mothers are recommended to exclusively breastfeed their infants for the first six months to provide optimal health for infant and mother. However, only 13.0% of mothers in Mississippi reached this milestone among infants born in 2015, which was far below the Healthy People 2020 objective of 25.5%. One factor that impacts breastfeeding success is access to certified lactation consultants, but low-income women may lack access due to an inadequate number of providers, unreliable transportation, rural location, or cost. The use of “telelactation” programs, which provide access to lactation consultants via video conferencing on internet connected devices, has been suggested …

Using Design Science Research To Develop A Conceptual Solution For Improving Knowledge Sharing In A Virtual Workspace, Lata Koneru

UNLV Theses, Dissertations, Professional Papers, and Capstones

Enhancements in technology have resulted in significant changes to day-to-day operations of organizations in the present day. One especially noteworthy change is the alteration in the nature of teams from being co-located, with face-to-face interaction, to virtual, with the involvement of information and communication technologies (ICT) to facilitate communication. This change in team character has had a downstream impact on a key element of an organization’s competitive edge, namely knowledge.

Overall, there is consensus that knowledge is a crucial facet of the competitive edge of an organization. Consequently, knowledge management, knowledge sharing, and organizational learning are essential components of an …

Community College Students’ Perceptions Of Their Academic Workload, William Neff

UNLV Theses, Dissertations, Professional Papers, and Capstones

One major barrier to success, for first-time, full-time college students, is course workload (Bowyer, 2012). How students respond to their situation and the barriers they face may influence decisions they make about classes in which they should enroll or those they should avoid, completing or dropping a class during the semester, and persisting from term-to-term and year-to-year. In an effort to help students succeed, colleges often give them a specified set of core courses and a specific or even prescribed pathway to complete the “general education” requirements. These core courses such as mathematics, communication, and English, among others, taken separately …

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 …

Cocoa, Postprandial Lipoproteins, And Inflammation In Type 2 Diabetes: A Secondary Data Analysis, Rickelle Tallent

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Type 2 Diabetes (T2D) is associated with dyslipidemia and chronic low-grade inflammation, which greatly increases the risk of cardiovascular disease (CVD) in this population. Hyperlipidemia and inflammation in the postprandial state substantially contribute to atherosclerosis development and CVD risk, and have shown to be exacerbated by high-fat meals. Dietary cocoa is a rich source of flavanols that is associated with favorable effects on cardiovascular health, such as improvements in the lipid profile and chronic inflammation, in non-diabetic adults.

Objective: To conduct a secondary data analysis using unpublished data from a previously conducted clinical study to determine whether acute cocoa …
