Evaluating a Sustainable Community Development Initiative Among the Lakota People on the Pine Ridge Indian Reservation (open access)

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

This thesis details my applied thesis project and experience in the evaluation of a workforce development through sustainable construction 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, …

Megachurches and Economic Development: A Theoretical Understanding of Church Involvement at the Local Level (open access)

Megachurches and Economic Development: A Theoretical Understanding of Church Involvement at the Local Level

Why do megachurches participate in economic development, and who benefits from their participation? Frumkin's framework for understanding nonprofit and voluntary action and extra-role behavior are theories tested to answer these questions. My research employs a mixed-methods research design conducted in two phases. In phase one, I analyze 42 responses to an online survey to provide data about the prevalence and nature of economic development activities offered by megachurches in the Dallas-Fort Worth and Houston-Sugar Land-Baytown Metropolitan Statistical Areas. Phase two involved 23 semi-structured telephone interviews with megachurch leadership to provide data that explains the rationale for why megachurches offer economic development activities and who benefits. Evidence from this research demonstrates that megachurches are participating in economic development for reasons consistent with both demand-side and supply-side arguments. Findings also show that megachurches take on extra-role behaviors for in response to community expectations and the values of members and staff. Implications for understanding partnership decisions and collaborations between faith-based organizations and local governments are discussed.

Synchrotron Radiation X-Ray Diffraction of Nickel-Titanium Shape Memory Alloy Wires During Mechanical Deformation (open access)

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

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 (open access)

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

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.

The Effects of Programmed Reinforcement and Chained Mastery Criteria on Yoga Pose Performance in Two Young Children with Autism (open access)

The Effects of Programmed Reinforcement and Chained Mastery Criteria on Yoga Pose Performance in Two Young Children with Autism

Community exercise can offer many benefits for children, including the opportunity to engage in physical activity and interact with peers in a social setting. Children with autism do not engage in as many community activities as their typical peers. This study examines conditions to teach young children to complete yoga poses to mastery. The effects of prompting, programmed reinforcers, and a chaining criteria were evaluated using a comparison design with two baselines and one intervention condition, replicated across two children with autism. Both children mastered performance of all four targeted yoga poses. The findings are discussed in the context of previous research on the benefits of yoga.

The Limits of Arbitrage and Stock Mispricing: Evidence from Decomposing the Market to Book Ratio (open access)

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

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 …

Acceptance Theories for Behavior in Conducting Research: Instructors in the Rajabhat University System, Thailand (open access)

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

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, …

Do contingency-conflicting elements drop out of equivalence classes? Re-testing Sidman's (2000) theory (open access)

Do contingency-conflicting elements drop out of equivalence classes? Re-testing Sidman's (2000) theory

Sidman's (2000) theory of stimulus equivalence states that all positive elements in a reinforcement contingency enter an equivalence class. The theory also states that if an element from an equivalence class conflicts with a programmed reinforcement contingency, the conflicting element will drop out of the equivalence class. Minster et al. (2006) found evidence suggesting that a conflicting element does not drop out of an equivalence class. In an effort to explain maintained accuracy on programmed reinforcement contingencies, the authors seem to suggest that participants will behave in accordance with a particular partitioning of the equivalence class which continues to include the conflicting element. This hypothesis seems to explain their data well, but their particular procedures are not a good test of the notion of "dropping out" due to the pre-establishment of equivalence classes before the conflicting member entered the class. The current experiment first developed unpartitioned equivalence classes and only later exposed participants to reinforcement contingencies that conflicted with pre-established equivalence classes. The results are consistent with the notion that a partition developed such that the conflicting element had dropped out of certain subclasses of the original equivalence class. The notion of a partitioning of an equivalence class seems to …

Competing Models of Hegemonic Masculinity in English Civil War Memoirs by Women (open access)

Competing Models of Hegemonic Masculinity in English Civil War Memoirs by Women

This thesis examines the descriptions of Royalist and Parliamentarian masculinity in English Civil War memoirs by women through a close reading of three biographical memoirs written by Margaret Cavendish, duchess of Newcastle; Lady Ann Fanshawe; and Lucy Hutchinson. Descriptions of masculinity are evaluated through the lens of Raewyn Connell's theory of hegemonic masculinity to understand the impact two competing models of masculinity had on the social and political culture of the period. The prevailing Parliamentarian hegemonic masculinity in English Civil War memoirs is traced to its origins before the English Civil War to demonstrate how hegemonic masculinity changes over time. The thesis argues that these memoirs provide evidence of two competing models of Royalist and Parliamentarian masculinities during the Civil War that date back to changes in the Puritan meaning of the phrase “man of merit”, which influenced the development of a Parliamentarian model of masculinity.

Female Friendship Films: A Post-Feminist Examination of Representations of Women in the Fashion Industry (open access)

Female Friendship Films: A Post-Feminist Examination of Representations of Women in the Fashion Industry

This thesis focuses on three fashion industry themed female friendship films: Pret-a-Porter/Ready to Wear (1994) by Robert Altman, The Devil Wears Prada (2006) by David Frankel, and The September Issue (2009) by R.J. Cutler. Female interpersonal relationships are complex – women often work to motivate, encourage and transform one another but can just as easily use tactics like intimidation, manipulation, and exploitation in order to save their own jobs and reputations. Through the lens of post-feminist theory, this thesis examines significant female interpersonal relationships in each film to illustrate how femininity is constructed and driven by consumer culture in the fashion industry themed films.

A Reexamination of the Dilution of Auditor Misstatement Risk Assessments: An Experimental Study of the Impact of Client Information Type, Workload, and PCAOB Guidance on Dilution (open access)

A Reexamination of the Dilution of Auditor Misstatement Risk Assessments: An Experimental Study of the Impact of Client Information Type, Workload, and PCAOB Guidance on Dilution

Many external parties such as investors, creditors, and regulatory agencies, use a company’s financial statements in their decision-making. In doing so, they rely on audit opinions on whether financial statements are fairly stated. However, evidence suggests that there are factors in the audit environment that influence auditor judgments. For example, nondiagnostic client information dilutes auditor judgments when compared to judgments based on diagnostic information alone, especially for less experienced auditors (Hackenbrack 1992; Hoffman and Patton 1997; Glover 1994; Shelton 1999). High time pressure conditions mitigate this effect by refocusing auditor attention toward relevant client information, therefore reducing the impact of nondiagnostic information (Glover 1994, 1997). This research study examines other common audit environment factors to determine if they too influence audit judgment results. An online questionnaire of 149 auditors, CPAs and other accounting professionals indicate that the inclusion of nondiagnostic client information results in a significant change in auditor judgments. The direction of this change follows a theorized pattern; risk assessments that were initially high are reduced, while those that were initially low are increased. Significance was not consistently found for a workload and PCAOB effect on auditor judgment. However, a comparison of the absolute value of dilution effect means …

Measuring Culture of Innovation: A Validation Study of the Innovation Quotient Instrument (open access)

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

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 (open access)

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

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 …

Oral History of Bonton and Ideal Neighborhoods in Dallas, Texas (open access)

Oral History of Bonton and Ideal Neighborhoods in Dallas, Texas

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.

Modeling the Role of Boundary Spanners-in-Practice in the Nondeterministic Model of Engineering Design Activity (open access)

Modeling the Role of Boundary Spanners-in-Practice in the Nondeterministic Model of Engineering Design Activity

Boundary spanners-in-practice are individuals who inhabit more than one social world and bring overlapping place perspectives to bear on the function(s) performed within and across each world. Different from nominated boundary spanners, they are practitioners responsible for the 'translation' of each small world's perspectives thereby increasing collaboration effectiveness to permit the small worlds to work synergistically. The literature on Knowledge Management (KM) has emphasized the organizational importance of individuals performing boundary spanning roles by resolving cross-cultural and cross-organizational knowledge system conflicts helping teams pursue common goals through creation of "joint fields" - a third dimension that is co-jointly developed between the two fields or dimensions that the boundary spanner works to bridge. The Copeland and O'Connor Nondeterministic Model of Engineering Design Activity was utilized as the foundation to develop models of communication mechanics and dynamics when multiple simultaneous interactions of the single nondeterministic user model, the BSIP and two Subject Matter Experts (SMEs), engage during design activity in the Problem-Solving Space. The Problem-Solving Space defines the path through the volumes of plausible answers or 'solution spaces' that will satisfice the problem presented to the BSIP and SMEs. Further model refinement was performed to represent expertise seeking behaviors and the physical …

Social Participation and Depression Among Elderly People in Greece (open access)

Social Participation and Depression Among Elderly People in Greece

The researcher had two objectives: first, explore how social involvement changes by age among Greek elderly, and second, examine the relationship between social involvement and depression by age among study participants, controlled for education, marital status, and gender. The researcher used data from the 2004 Survey of Health, Aging, and Retirement in Europe (SHARE) database subjecting a sample of 2,898 elderly aged 50 or older to analysis in terms of the study questions. Approximately 43% of the participants (n = 1,244) were males and 57% were females (n = 1,654). Study results showed Greek elderly participated more in religious activities and less in non-religious activities with increasing age. The study results showed the level of education did not have an effect on the level of religious or non-religious participation. Marital status could influence Greeks’ tendency to participate in religious activities, however, it did not have an effect on non-religious participation. Women are more likely to participate in religious activities than the men. The gender of the participants did not have an effect on non-religious participation. Older Greek elderly were more likely to be depressed than the younger elderly. Participation in religious activities was not shown to relate to decreasing the …

Indirect Fabrication of Lattice Metals with Thin Sections Using Centrifugal Casting

There is a wide range of applications for 3D printing technology with an additive manufacturing such as aerospace, automotive, marine and oil/gas, medical, consumer, electronics, building construction, and many others. There have been many pros and cons for 3D additive manufacturing. Even though 3D printing technology has many advantages: freedom to design and innovate without penalties, rapid iteration through design permutations, excellence mass customization, elimination of tolling, green manufacturing, minimal material wastes, energy efficiency, an enablement of personalized manufacturing. 3D additive manufacturing still has many disadvantages: unexpected pre- and post-processing requirement, high-end manufacturing, low speed for mass production, high thermal residual stress, and poor surface finish and dimensional accuracy, and many others. Especially, the issues for 3D additive manufacturing are on high cost for process and equipment for high-end manufacturing, low speed for mass production, high thermal residual stress, and poor surface finish and dimensional accuracy. In particular, it is relatively challenging to produce casting products with lattice or honeycomb shapes having sophisticated geometries. In spite of the scalable potential of periodic cellular metals to structural applications, the manufacturing methods of I∙AM Casting have been not actively explored nor fully understood. A few qualitative studies of I∙AM Casting has been …

Spray Cooling with HFC-134a and HFO-1234yf for Thermal Management of Automotive Power Electronics

This study aims to experimentally investigate the spray cooling characteristics for active two-phase cooling of automotive power electronics. Tests are conducted on a small-scale, closed loop spray cooling system featuring a pressure atomized spray nozzle. Two types of refrigerants, HFC-134a (R-134a) and HFO-1234yf, are selected as the working fluids. The test section (heater), made out of oxygen-free copper, has a 1-cm2 plain, smooth surface prepared following a consistent procedure, and would serve as a baseline case. Matching size thick film resistors, attached onto the copper heaters, generate heat and simulate high heat flux power electronics devices. The tests are conducted by controlling the heat flux in increasing steps, and recording the corresponding steady-state temperatures to obtain cooling curves. The working fluid is kept at room temperature level (22oC). Performance comparisons are made based on heat transfer coefficient (HTC) and critical heat flux (CHF) values. Effects of spray characteristics and liquid flow rates on the cooling performance are investigated with the selected coolants. Three types of commercially available nozzles that generate full-cone sprays with fine droplets are utilized in the tests. Effect of liquid flow rate is evaluated varying flow rates at 2, 3, 4 ml/s. The experimental results obtained from …
