If the rocket crashes before the player bails, player’s payoff is 0 (and they lose their bet).

The game boasts an unprecedented 97% RTP (Return to Player). For comparison, Atlantic City casino slots typically have a 91-92% RTP, while Vegas casino …

The Locals Casino As A Social Network – Can An Interconnected Community Of Players Detect Differences In Hold?, Jason D. Fiege, Anastasia (Stasi) D. Baran

International Conference on Gambling & Risk Taking

Abstract

It is difficult for individual players to detect differences in theoretical hold between slot machines without playing an unrealistically large number of games. This difficulty occurs because the fractional loss incurred by a player converges only slowly to the theoretical hold in the presence of volatility designed into slot pay tables. Nevertheless, many operators believe that players can detect changes in hold or differences compared to competition, especially in a locals casino market, and therefore resist increasing holds. Instead of investigating whether individual players can detect differences in hold, we ask whether a population of casino regulars who share …

Stake Size And Wagering In A Professional Betting Environment – When Data Affects Decision Making, Anthony Bedford, Tristan Barnett

International Conference on Gambling & Risk Taking

In this work, we discuss the structure of a number of professional wagering organisations, and how they attempt to deal with the “Ender’s Game” effect – when knowledge of the true nature of the ‘war being wagered’ may have affected the process and choice of betting. We analyse the responses from professional wagering and betting organisations, whom operate predominately in Horseracing and sportsbetting, and they identify the importance of separation of decisions around choices to make and the stakes and size of wagers that are linked to the decisions. The proposed model, practically carried out by one company, is an …

Why Teach? Exploring The Motivations And Expectations Of First-Year, Alternatively Certified Agriscience Teachers, Sarah E. Larose, Blake C. Colclasure, Anna J. Warner, Debra M. Barry, Edward W. Osborne

Journal of Research in Technical Careers

School-Based agricultural education increasingly depends upon alternatively certified (AC) teachers to teach agriculture across the United States. Understanding why these individuals become teachers is an important step to better recruit and retain educators who do not complete traditional preparation programs. The purpose of our study was to explore the backgrounds, motivations, and expectations of AC agriscience teachers joining the profession. Our study was guided by the social cognitive career theory and utilized a qualitative phenomenological approach. We interviewed seven AC agriscience teachers in Florida during their first-year teaching to explore their journey into teaching agricultural education. Six major themes were …

Investigating Students’ Career-Readiness In The Agricultural Sciences: A Phenomenological Case Study, Jean A. Parrella, Holli R. Leggette, Theresa P. Murphrey, Christi Esquivel, Anna Bates

Journal of Research in Technical Careers

The agricultural industry lacks qualified workers, suggesting students may not participate in opportunities that effectively develop their employability skills. We used a phenomenological case study approach to investigate Texas A&M University College of Agriculture and Life Sciences students’ career-readiness and factors influencing career-readiness. We conducted interviews with 19 juniors and seniors. Open coding procedures revealed five emergent themes—Career Advice-Seeking Behavior,Employability Skills Development, Network Establishment, Relevant Experiences, and Personal Growth. Findings indicate that students do not take advantage of University resources to help them with career preparation. Findings also revealed a lack of employability skills development, especially relating to …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The sharing of private information is a daunting, multifaceted, and expensive undertaking. Furthermore, identity management is an additional challenge that poses significant technological, operational, and legal obstacles. Present solutions and their accompanying infrastructures rely on centralized models that are susceptible to hacking and can hinder data control by the rightful owner. Consequently, blockchain technology has generated interest in the fields of identity and access control. This technology is viewed as a potential solution due to its ability to offer decentralization, transparency, provenance, security, and privacy benefits. Nevertheless, a completely decentralized and private solution that enables data owners to control their …

The Transaction Costs Of Federal Environmental Policy Changes: The Effects Of The Temporary Covid-19 Cwa Rollback On Local Water Systems, Jesse Lee Barnes

UNLV Theses, Dissertations, Professional Papers, and Capstones

An institutional dilemma exists between the Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA). US surface waters are protected from point-source pollution by the CWA. Community Water Systems (CWSs) that draw from these surface waters for potable purposes are required to treat that water to a level that meets SDWA health standards. Therefore, decreases in CWA regulations could lead to surface water quality declines and, thus, higher SDWA compliance costs for CWSs. This area of inquiry has become increasingly relevant due to Trump-era executive actions to try to decrease the federal government's role in multiple environmental policies, …

Studies Of Forward Projection Algorithms And Implementation On Pc And Fpga, Minsung Cho

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis first aims to understand how a part of the computed tomography (CT) algorithm called “forward projector” (FP) works and how it can be accelerated at a hardware level. Two methods of FP are defined and studied: pixel-driven and ray-driven. Both methods fundamentally use the property of line integral and Bresenham’s algorithm. As the result of the study of the two FP methods, the ray-driven algorithm implemented in C++ performed 35% faster than the pixe-driven algorithm implemented in Python.This thesis implements the ray-driven forward projector algorithm using field-programmable gate array (FPGA), making use of hardware-acceleration techniques. The result shows …

Outside, Looking In: A Dissertation On Mindful Walking And How Green Exercise Affects State Mindfulness And Connectedness To Nature, Dustin Wyatt Davis

UNLV Theses, Dissertations, Professional Papers, and Capstones

INTRODUCTION: Mindfulness, green exercise, and connectedness to nature are increasingly popular topics among academics and the public. These three topics overlap in the underexplored area called mindful green exercise. Mindful green exercise is a blend of mindful exercise and green exercise. Mindful exercise is physical exercise during which people pay attention on purpose without judgment to each new present moment. The person applies an accepting awareness to internal phenomena (thoughts, emotions, and bodily sensations) and external phenomena (objects and events in the environment). Green exercise is exercise performed outdoors in natural environments. Despite its name, green exercise does not only …

Mena Terrorism And The West: Explaining Why Terrorist Groups From The Middle East And North Africa Target Western Democracies, Michael A. Defeo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Terrorist groups from the Middle East and North Africa (MENA) region remain one of the most formidable threats to international security. While their organization and motives have been significantly different over time, a commonality is that they tend to disproportionately target Western democracies. This dissertation argues that this trend is mainly a consequence of the foreign policies that these states pursue in the region. These policies, in terms of support for Israel and interventionism, are theorized as being the precipitous causes of MENA terrorism. Likewise, it is argued that the democratic institutions and extents of globalization in these states are …

Information-Theoretic Model Diagnostics (Infomod), Armin Esmaeilzadeh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Model validation is a critical step in the development, deployment, and governance of machine learning models. During the validation process, the predictive power of a model is measured on unseen datasets with a variety of metrics such as Accuracy and F1-Scores for classification tasks. Although the most used metrics are easy to implement and understand, they are aggregate measures over all the segments of heterogeneous datasets, and therefore, they do not identify the performance variation of a model among different data segments. The lack of insight into how the model performs over segments of unseen datasets has raised significant challenges …

Desert springs are aquatic oases, being considered among the most diverse and imperiled ecosystems on Earth. Despite the ecological significance and threatened status of desert springs, few studies have surveyed the microorganisms in these systems or their interactions with other community members. The primary goal of this dissertation was to describe the major controls influencing the community ecology of prokaryotic and BMI communities in cold- and moderate-temperature desert springs of the southern hydrographic Great Basin. Chapter 1 provides a broad overview of spring ecosystems and of each chapter included in this dissertation. Chapter 2 documents the first-ever, regional-scale survey of …

The Closing Of One Black Box, The Opening Of Another: A Self-Study Of How An Instructional Coach Makes Decisions, Andromeda L. Hightower

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite the efforts of traditional and alternative teacher education programs (i.e. pre-service teacher education) in the United States, teachers frequently report feeling unprepared by the time they begin teaching full time in the classroom. Teachers with low levels of self-efficacy are correlated with lower job satisfaction, higher levels of stress and anxiety, and lower student achievement gains in the classroom. To assist with ameliorating these gaps, schools, districts, and private distributors provide training opportunities for teachers once they have begun the job (i.e. in-service teacher training) in the form of teacher professional development. Mainstream professional development approaches are traditionally simplistic …

Spectroscopic Studies On Silicon And Chalcopyrite Materials For Solar Energy Applications, Amandee Hua

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this dissertation, silicon-based materials for photovoltaics and chalcopyrite-based materials for photoelectrochemical water splitting are investigated using various spectroscopic and microscopic techniques. Although silicon dominates the photovoltaic market, further improvement can be made by using an alternative low temperature passivation approach. Currently, thermally grown SiO2 passivation is commonly used for silicon solar cells. However, this technique requires high processing temperatures (>800 °C), which increases the thermal budget, potentially decreases the bulk quality of Si, and can lead to difficulties in implementing in production lines. Here, a S-based passivation approach is studied that require lower processing temperatures of ~550 °C. …

Exploration Of H2o Ice At Extreme Conditions, Zachary M. Grande

UNLV Theses, Dissertations, Professional Papers, and Capstones

Static compression experiments on water ice are needed for precise characterization and discovery of new ice phases near room temperature. Here I present my efforts and the developments that have been made to reduce detrimental effects found in high-pressure experiments in order to acquire precise measurements on ice approaching 3 Mbar. Several key observations are made, relating to the phase transition of ice-VII to X, an intermediate phase I have named ice-VIIt and evidence of a post ice X phase. Some of these experiments have been replicated using D2O ice as well, in order to gain insight into nuclear quantum …

Individual Differences In Police Officers’ Decision Styles In Order Maintenance Policing, Damarrah Elisheba Jameson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Day-to-day police work tends to be in order maintenance policing. These encounters necessitate officer discretion in decision responses to manage them. These decision responses reflect an officer’s decision style which precedes the encounter and drives subsequent decision making to manage them. However, little is known about officer-level decision style. For example, whether an officer has a rational, intuitive, dependent, avoidant, or spontaneous decision style (Scott& Bruce, 1995). Police training in any format often lacks attention to decision styles. As such, an officer’s decision style is most likely associated with demographics (e.g., age, gender) and occupational self-efficacy – a reflection of …

Applying Instrumental Neutron Activation Analysis To Assess Air Pollution With Spanish Moss As A Bioindicator In The Low Country Of The Savannah River Basin, Christina Jiang

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Savanah River Basin is an area of 9,850 square miles that stretches from the border between South Carolina and Georgia, which empties into the Atlantic Ocean near Savannah, Ga. This area is home to surrounding cities, industrial sites, and the Savanah River Site. It is well documented that traffic, industrial operations, and agriculture contribute to worsening air pollution that needs to be monitored. While Tillandsia usneoides (Spanish moss) has been used in previous studies that prove it to be an effective biomonitor for air pollution and an accumulator of heavy metals, there have been no biomonitoring studies in the …

Solving Boundary Value And Initial Boundary Value Problems Of Partial Differential Equations Using Meshless Methods, Adam Johnson

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this dissertation, the methods of fundamental solutions (MFS) and the methods of particular solutions (MPS) are used to solve the boundary value problems of the Poisson and Helmholtz equations, where the particular solutions of the Poisson and Helmholtz equations in [13, 14] are used. Then the initial boundary value problems of the diffusion and wave equations are discretized into a sequence of boundary value problems of the Helmholtz equation by using either the Laplace transform or time difference methods along the lines of [8]. The Helmholtz problems are solved consequently in an iterative manner which leads to the solution …

A Generalized Family Of Exponentiated Composite Distributions With Applications To Insurance And Survival Data, Bowen Liu

UNLV Theses, Dissertations, Professional Papers, and Capstones

The concept of composite distributions was proposed in the early 2000s as a good parametric solution to model the data with heavy tails. Since the concept was proposed, it has been widely used in different areas, such as modeling insurance claim size data, predicting the risk measures in insurance data analysis, fitting survival time data, and modeling precipitation data. While a lot of the composite distributions demonstrated great performances in real applications, many commonly used composite distributions such as the inverse gamma-Pareto (IGP) or exponential-Pareto (EP), did not demonstrate great performances when fitting to several particular data sets. In order …

“But What About Me?”: How Memorable Messages Received During Catholic Sex Education Contribute To The Development Of Identity Gaps, Hannah Novak

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sex education in the United States is a widely debated issue. Christians have supported abstinence-based education in the United States for decades (Dent & Maloney, 2017). There are numerous studies that have examined how abstinence sex education is faulty, specifically religious sex education (Judge, 2020; Levand & Ross, 2021; Rasmussen, 2010; Reuther, 2008). Studies found that religious sex education led to mental, physical, and emotional health disparities in the United States (Baker et al., 2015; Nelson et al., 2017). This study explored how memorable messages received in Catholic sex education led to the formation of identity gaps in participants' lives. …
