The Effects Of Stock Distributions On Returns, Volatility, And Price, Jason Heavilin

Open Access Theses & Dissertations

This Dissertation investigates three issues regarding the effects of stock distributions on returns, volatility, and prices in an attempt to answer the questions why firms execute stock distributions and why the market appears to favor them. These questions have occupied academicians for at least 40 years (i.e., Fama et al (1969), Ohlson and Penman (1985), Rankine and Stice (1997), Angel (1997), and Crawford et al (2005) among many others).

Chapter 1 studies the notion that the stock market reacts more positive to stock dividends than to stock splits (Rankine and Stice, 1997). However, I find that the stock market does …

Multi-Expert Multi-Criteria Decision Making, Joel Henderson

Open Access Theses & Dissertations

Expert analysis and decisions are highly valued assets in a wide variety of fields, from social services to grant funding committees. However, the use of experts can be prohibitive due to either lack of availability or cost. As such, it is desirable to be able to replicate such decisions. However, there are many obstacles that impede an accurate simulation of expert decisions. For example, despite looking at the same information, two experts may disagree on the decisions. In addition, a single expert may make inconsistent decisions across similar scenarios.

In this work, we focus on multi-criteria decision making and in …

Immigration And Family Violence At The Household Level Of Analysis: Examining The Effects Of Immigrant Culture And Neighborhood Structure, Jorge Luis Hernandez

Open Access Theses & Dissertations

This study concerns the relationship between immigration and family violence at the household level of analysis. Previous studies have suggested that immigrant status - particularly first generation immigrant status - is not associated with crime. However, the same cannot be said about their descendants the second and third generations; as they are not as insulated from crime as their forefathers. This study measures the following variables which are relevant to the immigration and family violence relationship; immigrant generational status, acculturation levels, patriarchy, family oriented values, collective efficacy, surveillance, and measures of informal social control. This study finds that there is …

Market Reactions To Businesses' Actions Towards People With Disabilities: Making The Business Case In The International Context, Claudia Araceli Hernández González

Open Access Theses & Dissertations

From the business point of view, people with disabilities still suffer discrimination in employment and lack of accessibility as customers. Opposing, as recipients of philanthropic efforts many individuals and firms donate resources to improve the life of people with disabilities. These actions demonstrate how the majority of the population is still fixed in a medical model of disability by trying to repair the person to conform to the social norm, instead of accepting that many disabilities do not undermine other abilities. However, there is little evidence of how these actions impact the financial performance of the organization. This study attempts …

Perspectives On Feminine Cultural Gender Role Values From Latina Leaders And Community Residents, Nazanin Mina Heydarian

Open Access Theses & Dissertations

Marianismo and machismo are gender values prescribed to women and men respectively within Latino cultures. Characteristics associated with these gender values can be pro- or anti-social. Individuals, regardless of their own sex, self-identify with characteristics prescribed to both genders. There is little research examining how Latinos conceptualize and self-identify with both marianismo and machismo. The present study contributes to the literature by classifying how Latina leaders and non-leader community residents describe characteristics associated with marianismo and machismo. I identified characteristics of marianismo and machismo and their associated pro- and anti-social dimensions by means of a thematic analysis. The following characteristics …

Beneath The Kiss: Unearthing The Ideological Underpinnings Of Kay Jewelers Advertisements, Chelsea Nedlyn Hill

Open Access Theses & Dissertations

ABSTRACT

Advertising is a frequently used influential and persuasive means of communication, such as Kay Jewelers, a corporation whose advertising methods have been superficially appealing to a female audience. However, this study sought to investigate the ideological underpinnings associated with Kay Jewelers advertisements, employing an ideological criticism to argue through feminist theory that Kay Jewelers utilizes key elements of heteronormative love as a means to persuade and influence men to purchase their jewelry products. Through this underpinning of heteronormative romance, Kay Jewelers emphasizes the notion that an artifact, like a piece of jewelry, is necessary in order to properly express …

High Temperature Helical Tubular Receiver For Concentrating Solar Power System, Nazmul Hossain

Open Access Theses & Dissertations

In the field of conventional cleaner power generation technology, concentrating solar power systems have introduced remarkable opportunity. In a solar power tower, solar energy concentrated by the heliostats at a single point produces very high temperature. Falling solid particles or heat transfer fluid passing through that high temperature region absorbs heat to generate electricity. Increasing the residence time will result in more heat gain and increase efficiency. A novel design of solar receiver for both fluid and solid particle is approached in this paper which can increase residence time resulting in higher temperature gain in one cycle compared to conventional …

Sociocultural Influences On Perceived Risk In Latinos At Risk Of Developing Type 2 Diabetes, Allyson S. Hughes

Open Access Theses & Dissertations

Previous studies have shown that perceived risk is a predictor of positive health behaviors to avert preventative chronic conditions. As a major factor in the Health Belief Model, high levels of perceived risk may operate as a "perceived susceptibility" to disease and may function as a "perceived threat" that triggers action towards preventing the onset of disease (Champion & Skinner, 2008). Following an Ecodevelopmental Model approach in an effort to prevent prediabetes and type 2 diabetes (Castro, Shaibi & Boehm-Smith, 2009) includes understanding the potential protective effects of certain cultural factors (including sources of social support that can promote healthy …

Design Of A High Intensity Turbulent Combustion System, Mohammad Arif Hossain

Open Access Theses & Dissertations

In order to design next generation gas turbine combustor and rocket engines, a systematic study of flame structure at high intensity turbulent flow is necessary. The fundamental study of turbulent premixed combustion has been a major research concern for decades. The work is focused on the design and development of a high intensity turbulent combustion system which can be operated at compressible (0.3 < M < 0.5), preheated (T0=500K) and premixed conditions in order to investigate the 'Thickened Flame' regime. An air-methane mixture has been used as the fuel for this study. An optically accessible backward-facing step stabilized combustor has been designed for a maximum operating pressure of 6 bar. A grid has been introduced with different blockage ratios (BR = 54%, 61% & 67%) in order to generate turbulence inside the combustor for the experiment. Optical access is provided via quartz windows on three sides of the combustion chamber. Finite Element Analysis (FEA) is done in order to verify the structural integrity of the combustor at rated conditions. In order to increase the inlet temperature of the air, a heating section was designed to use commercially available in-line heaters. Separate cooling subsystems have been designed for chamber cooling and exhaust cooling. The LabVIEW software interface has been selected as the control mechanism for the experimental setup. A 10 kHz Time Resolved Particle Image Velocimetry (TR-PIV) system and a 3 kHz Planer Laser Induced Fluorescence (PLIF) system have been integrated with the system in order to diagnose the flow field and the flame respectively. The primary understanding of the flow field inside the combustor was achieved through the use of Detached Eddy Simulation (DES) by using commercially available software package ANSYS FLUENT. Preliminary validation is done by 10 kHz TR-PIV technique. Both qualitative and quantitative analysis have been done for CFD and experiment. Major flow parameters such as average velocity, fluctuation of velocity, kinetic energy, and turbulent intensity have been calculated for two distinct Reynolds number (Re = 815 & 3500). PIV results are compared with CFD results which show significant agreement with each other.

Rents, Loyalty, And The Economy: How An Unstable Economy Plays A Role In The Occurrence Of Coups D'État, Alexandra Elizabeth Infanzon

Open Access Theses & Dissertations

This Thesis examines why coups d'état still occur, regardless of institution type, in some states but not others. Building off Wintrobe's and Hiroi and Omori's observations, an elite theory is presented that attributes the success of avoiding coups lies in both the stability of economic growth and a system of internal incentives that create a direct link between the government and the people. Without either present, the elite in government are not constrained from engaging in undemocratic behavior and usurping power, ultimately resulting in coups. Using a zero-inflated negative binomial logistic regression, indicators of economic stability and internal loyalty systems …

The Role Of P62/Imp2 In Breast Cancer Progression, Yang Li

Open Access Theses & Dissertations

Breast cancer is one of the most common types of cancer in women. In most patients with breast cancer, it is not the primary tumor that leads to death, but rather metastatic tumors. Once breast cancer spreads to other organs in the body, the disease becomes almost incurable. It is estimated that about 20% to 50% of patients diagnosed with primary breast cancer will develop metastatic disease. Considering this, it is important to understand the molecular and cellular mechanisms behind metastatic breast cancer and to identify new proteins that regulate the metastatic process. These proteins may be used as targets …

Health Assessment For Loved Ones: Development And Validation Of A New Instrument To Measure Well-Being In Military Spouses, Christi Luby

Open Access Theses & Dissertations

Since 2001, over 2.7 million US troops have deployed in support of the ongoing conflicts in the Middle East. Combat stress and deployments affect Service members, and consequently affect their spouses/intimate partners. In addition, these spouses often act as the social support system to other spouses experiencing traumatic events, such as death, injury, or illness of their deployed soldier. These indirect exposures to trauma may make spouses vulnerable; yet little research has focused on how the lived experiences of spouses of deployed and returning US Service members have affected their well-being. The purpose of this three-part study was to develop …

On The Path To Multi-Electron Redox Chemistry With Bimetallic Systems, Nathalie Metta

Open Access Theses & Dissertations

The following study is presented in two sections, in the first, a novel digold (II) complex with semi-bridging chlorides supported by two bulky formamidinates was synthesized for the purpose of studying late-transition metal multi-electron redox chemistry. Electrochemical analysis shows one non-reversible reduction. Although the electrochemistry of this complex is restricted, the compound shows interesting electronic properties. The crystal structure reveals a geometry distortion of the Au2ï?­-Cl2 core. The coupling of an unoccupied orbital and an occupied orbital through a vibrational mode, causes a distortion in the geometry of the molecule lowering the D2h symmetry to C2h. This is an example …

Bayesian Adaptive Penalized Splines In Nonparametric Regression And In Spectral Time Series Analysis, Luis Angel Mora

Open Access Theses & Dissertations

A Bayesian approach to nonparametric regression using Penalized splines (P-splines) is presented. The approach uses the linear mixed model formulation of P-spines. The usual model assumes a single value for the smoothing parameter controlling the amount of smoothing of the fitted function. The main focus of the Thesis is on spatially adaptive smoothing where the smoothing parameter is a function of the covariate so that different amounts of smoothing are applied in different regions of the covariate. An application to spectral time series analysis will be demonstrated. Markov chain Monte Carlo methods are used to make inference based on the …

CrkL remains understudied but it has been shown to interact with Bcr-Abl in chronic myelogenous leukemia (CML) and is currently being used as a prognostic marker for patients by evaluating phosphorylation levels. Though regulation of CrkL by tyrosine phosphorylation has been studied extensively, the role of serine and threonine phosphorylation in an IL-2 dependent …

Re-Specifying The Sacred Values Scale, Adon Lee Neria

Open Access Theses & Dissertations

An object or value becomes sacred when a person feels compelled to protect and admire it. When a person holds a Sacred Value (SV) they are less likely to accept compromises, or "taboo tradeoffs," to that value and will behave less rationally to protect it from perceived slights. Though research on SV has replicated well, there has yet to be a popularized scale measuring it. A previous attempt at developing a multidimensional scale for measuring the degree to which a person holds any value as sacred was made that resulted in a 15-item measure. Though this version demonstrated good predictive …

Rare Pride Campaigns: Evaluating Participatory Communication In Conservation Efforts Throughout Indonesia, Lauren Elizabeth Perez

Open Access Theses & Dissertations

Communication scholars who study international development and social change have found that if facilitators of social change hope to find positive, lasting solutions to complex social and environmental issues, they must incorporate more participatory approaches. However, even the practitioners with the most noble intentions oftentimes fall short of facilitating truly participatory practices because their strategies are the product of linear processes for evaluating the change context. In this study, I apply Lennie and Tacchi's (2014) approach to evaluating communication for development in a case study of Pride Campaigns implemented by managers throughout Indonesia who partnered with the conservation non-governmental organization …
