Return-Entry Risk Communication Following 2012 Hurricane Sandy

Return-Entry Risk Communication Following 2012 Hurricane Sandy

Date: December 2015
Creator: Manandhar, Rejina
Description: Within risk communication, much is understood about pre-event warning related to evacuation and sheltering; however risk communication during the return-entry phase when ending evacuations has been largely under-studied in the disaster literature. Understanding of the return-entry risk communication process is important because returning early or prior to issuance of the all-clear message can make returnees susceptible to post-disaster risks, and also hamper post-disaster activities such as debris removal, traffic management, utility restoration and damage assessments. Guided by the Warning Components Framework and the Theory of Motivated Information Management, this dissertation focuses on risk communication as it pertains to organizational behavior during the return-entry process by examining how local emergency management organizations develop, disseminate and monitor return-entry messages. The data is collected through semi-structured telephone interviews with local emergency management organizations that managed return-entry following Hurricane Sandy. The findings of the study indicate that local emergency management organizations required information on post-disaster threats, damages, and utility and infrastructure condition in order to develop return-entry strategy for their community. Organizations improvised to their existing risk communication measures by adopting creative ways for information dissemination to the evacuees. They also utilized active and passive approach to monitor public response to the return-entry messages.

Evaluating a Sustainable Community Development Initiative Among the Lakota People on the Pine Ridge Indian Reservation

Evaluating a Sustainable Community Development Initiative Among the Lakota People on the Pine Ridge Indian Reservation

Access: Use of this item is restricted to the UNT Community.
Date: December 2015
Creator: Mosman, Sarah
Description: This thesis details my applied thesis project and experience in the evaluation of a workforce development through sustainable constructio program. It describes the need of my client, Sweet Grass Consulting and their contractual partner, the Thunder Valley Community Development Corporation, in the evaluation of Thunder Valley CDC's Workforce Development through Sustainable Construction Program. My role involved the development of an extensive evaluation package for this program and data analysis of evaluation materials to support Thunder Valley CDC's grant-funded Workforce Development Program. I place the efforts of Thunder Valley CDC in the context of their community, the Pine Ridge Reservation of the Lakota People, and within an historical and contemporary context to highlight the implications of the efforts of Thunder Valley CDC. Using the theoretical frameworks of cultural revitalization and community economic development, I attempt to highlight two important components of Thunder Valley CDC's community development efforts - cultural revitalization for social healing, and development that emphasizes social, community and individual well-being. Thunder Valley CDC's Workforce Development through Sustainable Construction Program is still in its early stages, and so this first year of implementation very much represented a pilot phase. However, while specific successes are difficult to measure at this point, ...

Measuring Culture of Innovation: A Validation Study of the Innovation Quotient Instrument

Measuring Culture of Innovation: A Validation Study of the Innovation Quotient Instrument

Date: December 2015
Creator: Danks, Shelby
Description: The ability for an organization to innovate has become one of the most important capabilities needed in the new knowledge economy. The research has demonstrated that an organization’s culture of innovation in particular predicts organizational innovativeness across multiple industries. To provide support to these organizations in their abilities to understand the culture of innovation, researchers have developed instruments to measure culture of innovation, and while many of these instruments have been widely used to inform organizational opportunities for improvement, few of these instruments have been validated or replicated beyond their initial use. The current study employs multiple factor analytic methods to validate the factor structure of the Innovation Quotient instrument developed by Rao and Weintraub and assess the extent to which the instrument is reliable for multiple organizational groups. The results of this study, as well as implications for researchers interested in culture of innovation, are presented.

Single Notch versus Multi Notch Credit Rating Changes and the Business Cycle

Single Notch versus Multi Notch Credit Rating Changes and the Business Cycle

Date: December 2015
Creator: Poudel, Rajeeb
Description: Issuers’ credit ratings change by one or more notches when credit rating agencies provide new ratings. Unique to the literature, I study the influences affecting multi notch versus single notch rating upgrades and downgrades. For Standard & Poors data, I show that rating changes with multiple notches provide more information to the market than single notch rating changes. Consistent with prior literature on the business cycle, I show that investors value good news rating changes (upgrades) more in bad times (recession) and that investors value bad news rating changes (downgrades) more in good times (expansion). I model and test probit models using variables capturing the characteristics of the previous issuer’s credit rating, liquidity, solvency, profitability, and growth opportunity to determine the classification of single notch versus multi notch rating changes. The determinants of multi notch versus single notch rating changes for upgrades and downgrades differ. Business cycle influences are evident. Firms that have multi notch rating upgrades and downgrades have significantly different probit variables vis-à-vis firms that have single notch rating upgrades and downgrades. The important characteristics for determining multiple notch upgrades are a firm’s prior rating change, prior rating, cash flow, total assets and market value. The important characteristics ...

The Limits of Arbitrage and Stock Mispricing: Evidence from Decomposing Market to Book Ratio

The Limits of Arbitrage and Stock Mispricing: Evidence from Decomposing Market to Book Ratio

Date: December 2015
Creator: Alshammasi, Naji Mohammad
Description: The purpose of this paper is to investigate the effect of the "limits of arbitrage" on securities mispricing. Specifically, I investigate the effect of the availability of substitutes and financial constraints on stock mispricing. In addition, this study investigates the difference in the limits of arbitrage, in the sense that it will lead to lower mispricing for these stocks, relative to non-S&P 500 stocks. I also examine if the lower mispricing can be attributed to their lower limits of arbitrage. Modern finance theory and efficient market hypothesis suggest that security prices, at equilibrium, should reflect their fundamental value. If the market price deviates from the intrinsic value, then a risk-free profit opportunity has emerged and arbitrageurs will eliminate mispricing and equilibrium is restored. This arbitrage process is characterized by large number of arbitrageurs which have infinite access to capital. However, a better description of reality is that there are few numbers of arbitrageurs to the extent that they are highly specialized; and they have limited access to capital. Under these condition arbitrage is no more a risk-free activity and can be limited by several factors such as arbitrage risk and transaction costs. Other factors that are discussed in the literature ...

Synchrotron Radiation X-Ray Diffraction of Nickel-Titanium Shape Memory Alloy Wires during Mechanical Deformation

Synchrotron Radiation X-Ray Diffraction of Nickel-Titanium Shape Memory Alloy Wires during Mechanical Deformation

Access: Use of this item is restricted to the UNT Community.
Date: December 2015
Creator: Zhang, Baozhuo
Description: Shape memory alloys (SMAs) are a new generation material which exhibits unique nonlinear deformations due to a phase transformation which allows it to return to its original shape after removal of stress or a change in temperature. It shows a shape memory effect (martensitic condition) and pseudoelasticity (austenitic condition) properties depends on various heat treatment conditions. The reason for these properties depends on phase transformation through temperature changes or applied stress. Many technological applications of austenite SMAs involve cyclical mechanical loading and unloading in order to take advantage of pseudoelasticity, but are limited due to poor fatigue life. In this thesis, I investigated two important mechanical feature to fatigue behavior in pseudoelastic NiTi SMA wires using high energy synchrotron radiation X-ray diffraction (SR-XRD). The first of these involved simple bending and the second of these involved relaxation during compression loading. Differential scanning calorimetry (DSC) was performed to identify the phase transformation temperatures. Scanning electron microscopy (SEM) images were collected for the initial condition of the NiTi SMA wires and during simple bending, SEM revealed that micro-cracks in compression regions of the wire propagate with increasing bend angle, while tensile regions tend to not exhibit crack propagation. SR-XRD patterns were analyzed ...

Taking the Irish Pulse: A Revitalization Study of the Irish Language

Taking the Irish Pulse: A Revitalization Study of the Irish Language

Date: December 2015
Creator: Roloff, Donna Cheryl
Description: This thesis argues that Irish can and should be revitalized. Conducted as an observational study, this thesis focuses on interviews with 72 participants during the summer of 2013. All participants live in the Republic of Ireland or Northern Ireland. This thesis investigates what has caused the Irish language to lose power and prestige over the centuries, and which Irish language revitalization efforts have been successful. Findings show that although, all-Irish schools have had a substantial growth rate since 1972, when the schools were founded, the majority of Irish students still get their education through English-medium schools. This study concludes that Irish will survive and grow in the numbers of fluent Irish speakers; however, the government will need to further support the growth of the all-Irish schools. In conclusion, the Irish communities must take control of the promotion of the Irish language, and intergenerational transmission must take place between parents and their children.

Acceptance Theories for Behavior in Conducting Research: Instructors in the Rajabhat University System, Thailand

Acceptance Theories for Behavior in Conducting Research: Instructors in the Rajabhat University System, Thailand

Date: December 2015
Creator: Laksaniyanon, Benchamat
Description: Responding to globalization and its effects on education and research development, the Thai government decided to push all public universities to become autonomous and establish a system of quality assurances. The establishment of quality assurances has had a large impact on many Thai instructors, especially in new public universities. Thai instructors are now forced to more focus on conducting research because the number of research publications is regarded as one of the main criteria for quality universities. The purpose of this study is to investigate the key factors, at the individual and university levels, which impact on the instructors' behavior in conducting research of the full-time instructors in the faculty of Management Science from the Rajabhat Universities in Thailand. The current study will help explain how and why the instructors accept or refuse to conduct research and provide insight into the salient factors motivating the instructors to produce more research by conducting HLM. Data were collected from 694 participants at 37 institutions via a questionnaire survey. The findings revealed that there was no difference among these 37 universities on behavior in conducting research. The key factors statistically influencing behavior in conducting research of the instructors were facilitating conditions, academic degree, ...

Oral History of Bonton and Ideal Neighborhoods in Dallas, Texas

Oral History of Bonton and Ideal Neighborhoods in Dallas, Texas

Date: December 2015
Creator: Payne, Briana
Description: The Bonton and Ideal neighborhoods in Dallas Texas, developed in the early 1900s, experienced physical and social decay throughout the 1980s. Neighborhood organizations and resident activism were vital to the rebirth of the community in the 1990s. Current revitalization efforts taking place there have been a source of contention as the neighborhood continues to overcome inequalities created by decades of racialized city planning initiatives. This thesis focuses on how the structuring structure of whiteness has historically affected, and continues to affect, the neighborhoods of Ideal and Bonton, as well as acts to identify how black residents have navigated their landscape and increased their collective capital through neighborhood activism.
