Numerical Methods For Option Pricing Under The Two-Factor Models, Jiacheng Cai

UNLV Theses, Dissertations, Professional Papers, and Capstones

Pricing options under multi-factor models are challenging and important problems for financial applications. In particular, the closed form solutions are not available for the American options and some European options, and the correlations between factors increase the complexity and difficulty for the formulations and implements of the numerical methods.

In this dissertation, we first introduce a general transformation to decouple correlated stochastic processes governed by a system of stochastic differential equations. Then we apply the transformation to the popular two-factor models: the two-asset model, the stochastic volatility model, and the stochastic interest rate models. Based on our new formulations, we …

Can Questionnaires Capture Inner Experience? A Validation Study Of The Nevada Inner Experience Questionnaire, Stefanie Alison Moynihan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Self-report questionnaires that explore human experience sometimes produce substantially discrepant results from careful sampling-based methods such as Descriptive Experience Sampling (DES). One explanation is that questionnaires may not be inquiring about the same phenomena that sampling discovers. To investigate this, we conducted two studies. Study 1 (N =260) created the Nevada Inner Experience Questionnaire (NIEQ), designed to measure the frequency of the same five phenomena of inner experience that DES frequently finds (the “5FP”: inner speaking, inner seeing, unsymbolized thinking, feeling and sensory awareness). Study 1 explored the construct validity of the NIEQ, finding it to be reliable and psychometrically …

Understanding Progenitors Of Gamma Ray Bursts With Multi-Wavelength Properties, Ye Li

UNLV Theses, Dissertations, Professional Papers, and Capstones

Gamma-ray bursts (GRBs) are among the most brilliant explosions in the universe, named for their intense, seconds-duration $\gamma$-ray emission. They are generally classified into two categories according to the durations of their $\gamma$-ray emission: the long-duration GRBs (LGRBs) with durations more than 2 seconds, and the short-duration GRBs (SGRBs) with durations less than 2 seconds. Most SGRBs are believed to originate from mergers of compact stars (e.g., neutron star-neutron star and neutron star-black hole; also known as Type I GRBs by their physical mechanism), while the LGRBs are thought to originate from core-collapse of massive stars (Type II). In addition …

Social Cognition In Children With Attention-Deficit/Hyperactivity Disorder, Elyse Parke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder, which impacts behavioral outcomes, including social functioning. Children with ADHD demonstrate impairment across a number of social domains, including aggressive behavior, poor social skills, and higher rates of Oppositional Defiant Disorder compared to typically developing peers. However, the underlying neurocognitive underpinnings of these poor social outcomes are unclear. Furthermore, little is known regarding the impact of ADHD symptomatology on aspects of social cognition. Inattention, hyperactivity, and impulsivity may differentially impact components of social cognition. Determining whether performance on social cognition tasks is predictive of social skills and problem behaviors is also an area …

Athlete Alcohol Use And Alcohol-Related Consequences: The Role Of Drinking Motives, Michelle Pitts

UNLV Theses, Dissertations, Professional Papers, and Capstones

Intercollegiate athlete alcohol use, particularly in softball athletes, is higher compared to nonathletes and they experience greater alcohol-related consequences. Motivation to drink alcohol is a strong predictor of alcohol use and alcohol-related problems in college students, including collegiate athletes. Drinking motives are reasons why people consume alcohol, including reasons that are specific to the context of athletics. Two dimensions underlie drinking motives: positively or negatively reinforcing motives and internal or external motives (Cox & Klinger, 1988). In this study the influence of sport-related and general drinking motives on alcohol use and negative alcohol-related consequences was examined in 721 collegiate softball …

Societal Opinon Of Government And Private Agencies’ Surveillance Capabilities Post 9-11, Stephanie E. Kaplan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the September 11, 2001 attacks, the United States has placed an increased focus upon government and private agencies to engage in surveillance practices in order to combat terrorism. The passing of the United States PATRIOT ACT (2001) expanded the surveillance capabilities of law enforcement officials thus allowing both federal and state agencies to legally wiretap a range of communication devices. Under the justification of “fighting terrorism,” federal and state agencies now have more access to sensitive data on/about a range of persons including subjects of interest. Legal scholars (Bam, 2015, as well as the American Civil Liberties Union (ACLU), …

Conflicted Provision: Exploring The Intersection Of Social Support And Deception, Courtney Lane Mcdaniel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Social support and deception are both significant elements of close relationships. Social support involves verbal and nonverbal behaviors that are used when an individual is trying to help another person (Vangelisti, 2009). Social support is imperative to relationships, and as such, plays a large role within friendships, romantic relationships, and professional relationships alike. Research has suggested that friends in particular are one of the most enduring and irreplaceable sources of social support (Burleson, 1994; Burleson & Goldsmith, 1998; Floyd, 1995; Floyd & Parks, 1995). Thus, because friends comprise the strongest support system for many individuals, studying how deceptive communication functions …

Cli-Fi Cinema: An Epideictic Rhetoric Of Blame, Chloe Louise Powell

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis analyzes the symbolic mechanisms of guilt-redemption as developed by Kenneth Burke within two climate fiction (cli-fi) films: The Day the Earth Stood Still (2008), and Interstellar (2014). In doing so, this thesis offers an account of: (1) each film’s role in providing their audience temporary assuagement of climate change related guilt, and (2) each film’s role in transmitting values and “attitudes” to build and strengthen communities. Because cli-fi films begin from a dystopic vision of a possible future, it fulfills the "blame" function of epideictic discourse to provoke and inspire the "ecological imagination." Through this provocation, the audience …
