An Exploratory Study Of Campus Ministries Affiliated With Churches Of Christ In Ghana, Frank Obeng Essien

Electronic Theses and Dissertations

The Churches of Christ in Ghana commemorated 50 years of the Restoration Movement in Ghana in 2012. As part of the historical development of this community in Ghana, the number of individuals who have accessed higher education through the various institutions of higher learning in the country have increased significantly. This development also led to the emergence of campus churches to meet the spiritual needs of members of this faith-tradition as they pursue academic interests on the various university campuses. This development notwithstanding, almost no literature exists which provides a record of the historical evolution of these campus churches and …

This study surveyed the 64 employees at the ATCPHD with the Organizational Climate Measure (OCM). Forty employees participated in the study. The study determined that the climate of the ATCPHD, according to Competing Values Framework (CVF), was the Human Relations organizational climate with a secondary climate of Relational Goals. …

Minding Ps And Qs: The Political And Policy Questions Framing Health Care Spending, William M. Sage

Faculty Scholarship

Tracing the evolution of political conversations about health care spending and their relationship to the formation of policy is a valuable exercise. Health care spending is about science and ethics, markets and government, freedom and community. By the late 1980s the unique upward trajectory of post-Medicare U.S. health care spending had been established, recessions and tax cuts were eroding federal and state budgets, and efforts to harness market forces to serve policy goals were accelerating. From the initial writings on “managed competition,” through the failed Clinton health reform effort in the early 1990s, to the passage of the Affordable Care …

A Build System For Benchmarking And Comparison Of Competing System Implementations, Anthony J. Bentley

Electrical and Computer Engineering ETDs

When developing a hardware or software system, the problem at hand may lend itself to multiple solutions. During the implementation process for such systems, it can be helpful to prototype multiple versions that use distinct paradigms, and determine the efficiency of each according to some metric, such as execution time. This paper presents a portable, lightweight build system designed for easy benchmarking and verification of competing implementations of an algorithm. Also presented is a sample project that uses this system to compare the performance and correctness of CPU, GPU, and FPGA implementations of a signal recovery algorithm

How The United States Uses The Trans-Pacific Partnership To Contain China In International Trade, Daniel C.K. Chow

Chicago Journal of International Law

The Trans-Pacific Partnership (TPP) was signed on February 5, 2016 by its twelve members and is now open for ratification. If ratified, the TPP will be the largest mega free trade area in history and will encompass forty percent of world trade. The U.S. led the TPP negotiations and deliberately excluded China from the negotiations. This ploy by the U.S. was a calculated effort to contain China and to shift power in trade in the Asia-Pacific from China to the U.S. China now appears to face a difficult choice. China can join the already concluded TPP, with its text largely …

Unilateral Corporate Regulation, William Magnuson

Chicago Journal of International Law

Corporations today wield unprecedented power in politics and society, and they have a tremendous effect on human welfare around the globe. At the same time, they are increasingly difficult to regulate. Corporations are savvy and mobile, and they can relocate to avoid burdensome domestic regulation with surprising ease. The agility of corporations creates a dilemma for government decisionmakers seeking to balance the need to attract the wealth that corporations create with the desire to pursue other policy priorities. One approach that governments have used to address this dilemma is international cooperation, and a growing number of scholars have argued that …

Inefficient Efficiency: Crying Over Spilled Water, Vanessa Casado-Pérez

Faculty Scholarship

As the drought in Western states worsens, the agricultural sector is being criticized for failing to adopt technical responses, such as shifting to less water-demanding crops and state-of-the-art irrigation systems, in a timely manner. However, these responses can have the reverse effect: they can increase water consumption. Technological responses alone are insufficient to reduce water consumption if unaccompanied by changes in how the law defines and allocates water rights. This paper proposes a redefinition of water rights to ensure that changes in crops or irrigation techniques are socially efficient.

In the West, which uses the doctrine of prior appropriation to …

Meridians 15:1, Karsonya Wise Whitehead

Meridians: Feminism, Race, Transnationalism

With the increasingly high stakes nature of teaching and the ongoing push to teach within the adopted Common Core, there appears to be very little room for teachers to incorporate the voices and experiences of anyone whose life is not already embedded within the curriculum....

Ancient Maya Agricultural Resources In The Rio Amarillo Valley Near Copán, Honduras, Bryce Matthew Brown

Theses and Dissertations

The purpose of this study was to use soil physical and chemical analyses to better understand the ancient agricultural landscape around the ancient Maya cities of Rio Amarillo and Piedras Negras, two tributary sites to Copan, Honduras. Our primary objective was to determine whether a mass erosion event around 800 A.D. occurred which could have caused crop failure and famine or if stable soil conditions persisted during the collapse of these city-states. Stable carbon isotope analysis of the humin fraction of the soils showed that much of this valley was used anciently for agriculture, including hillslopes and hilltops; however, there …

How A Systematic Approach To Uncertainty Quantification Renders Molecular Simulation A Quantitative Tool In Predicting The Critical Constants For Large N-Alkanes, Richard Alma Messerly

Theses and Dissertations

Accurate thermophysical property data are crucial for designing efficient chemical processes. For this reason, the Design Institute for Physical Properties (DIPPR 801) provides evaluated experimental data and prediction of various thermophysical properties. The critical temperature (T_c), critical density (ρ_c), critical pressure (P_c), critical compressibility factor (Z_c), and normal boiling point (T_b) are important constants to check for thermodynamic consistency and to estimate other properties. The n-alkane family is of primary interest because it is generally assumed that other families of compounds behave similarly to …

Selecting Cloud Platform Services Based On Application Requirements, Bridger Ronald Larson

Theses and Dissertations

As virtualization platforms or cloud computing have become more of a commodity, many more organizations have been utilizing them. Many organizations and technologies have emerged to fulfill those cloud needs. Cloud vendors provide similar services, but the differences can have significant impact on specific applications. Selecting the right provider is difficult and confusing because of the number of options. It can be difficult to determine which application characteristics will impact the choice of implementation. There has not been a concise process to select which cloud vendor and characteristics are best suited for the application requirements and organization requirements. This thesis …

Climate Disobedience, Maxine Burkett

Duke Environmental Law & Policy Forum

In sharp contrast to the flurry of legal and policy-oriented efforts of years past, climate activists today employ protest and nonviolent civil disobedience to advance their agenda for rapid and ambitious mitigation and adaptation. In so doing, activists make explicit references to the storied past of defining social movements in American history—notably the anti-slavery movements of the 19th century and the civil rights movement of the 20th—and draw direct comparison to the moral failure igniting the relevant social movements. This article examines a topic largely ignored by the legal academy, the emerging climate movement, to assess the usefulness of its …

Transgender Bathroom Rights, Catherine Jean Archibald

Duke Journal of Gender Law & Policy

After winning the right to same-sex marriage in all 50 states in June, 2015, the LGBT community is once again battling in court for its rights, this time for the right of transgender people to use bathrooms and locker rooms that match their gender identity. In its “Dear Colleague Letter on Transgender Students,” the Federal Government has recently interpreted federal law as requiring that transgender students be permitted to use bathroom and locker rooms that correspond with their gender identity in schools receiving federal funding. In two separate lawsuits, 20 states have challenged the legitimacy of this interpretation.

Spatiality Of The Stages Of Genocide: The Armenian Case, Shelley J. Burleson, Alberto Giordano

Genocide Studies and Prevention: An International Journal

This article describes the construction of a historical GIS (HGIS) of the Armenian genocide and its application to study how the genocide unfolded spatially and temporally using stage models proposed by Gregory Stanton. The Kazarian manuscript provided a daily record of events related to the genocide during 1914-1923 and served as a primary source. Models outlining and describing the stages of genocide provide a structured and vetted approach to studying the spatial and temporal aspects of the genocidal process, especially genocide by attrition. This article links HGIS to a qualitative, historical source and describes the uncertainties that arise when mapping …

Understanding Adolescents' Unique Experience Of Happiness Within The Family: Bridging Multiple Perspectives Of Adolescents, Parents, And Siblings, Marsha Cohen

Dissertations

The purpose of this phenomenological study was to explore the essence of middle adolescents'; unique experiences of happiness within the family system from the multiple perspectives of adolescents, their parents, and their siblings. Another goal was to make thematic comparisons between and within families in order to better understand the complexity and development of the phenomenon for adolescents. Seven families participated in this study. Each family consisted of a middle adolescent, a parent, and a sibling, yielding a total of 21 participants. A semistructured interview was conducted with each participant. Data were analyzed using Moustakas's (1994) modification of the Stevick-Colaizzi-Keen …

A Monte Carlo Simulation Comparing The Statistical Precision Of Two High-Stakes Teacher Evaluation Methods: A Value-Added Model And A Composite Measure, Bryden Michael Spencer

Dissertations

Value-added models are a class of growth models used in education to assign responsibility for student growth to teachers or schools. For value-added models to be used fairly, sufficient statistical precision is necessary for accurate teacher classification. Previous research indicated precision below practical limits. An alternative approach has been explored in which value-added models are incorporated into composite measures of teacher quality alongside subjective indicators. The aim of the current research was to explore the relative precision of the two evaluative approaches using simulated data. It was found that the composite measure produced fewer classification errors than the stand-alone value-added …

The Bayesian Method Of Estimation For The Number Of Latent Classes In Growth Mixture Models, Chittanun Sitthisan

Dissertations

It is widely accepted that blindly specifying an incorrect number of latent classes may result in misidentifying the class membership of observations and in inconsistently estimated parameters. The current dissertation examined the Bayesian method to estimate the number of latent classes in growth mixture models. The procedure for estimating the number of latent classes was developed via Markov chain Monte Carlo using the Metropolis-Hastings algorithm. The key idea was to construct the likelihood function and then specify the prior information toward the number of latent classes (K), and then calculate the posterior distribution for K. Simulated observations were generated by …

A Reliability Generalization Of The Parental Authority Questionnaire, Lynn M. Dean

Dissertations

How parents interact with their children impacts many crucial facets of children‟s lives. Over the last 4 decades, researchers have identified four different parenting styles: authoritative, authoritarian, permissive, and disengaged. Hundreds of studies conducted all over the world, have identified correlations between parenting style and many different child outcomes (e.g., academic achievement, coping, self-esteem, and decision-making abilities). The interpretability of these results has been limited by the unknown psychometric properties of the instruments used. The building block of any psychometrically sound measure is instrument reliability, which is the degree of non-error variance in the instrument‟s results. Sound estimates of reliability …

Faculty's Knowledge, Pedagogy, And Integration Levels In The Implementation Of Ipads As An Instructional Tool, Xin Wang

Dissertations

Current literature showed there is a need to help faculty improve their iPad integration practices. Using a sequential mixed-methods design, the researcher explored the relationship among faculty’s iPad integration levels, their teachers’ knowledge (TPACK), and pedagogy among faculty members who had integrated iPads into their teaching for at least two semesters. The data were collected with a cross-section questionnaire, follow-up interviews and artifacts. Responses were collected respectively with the three sections of the questionnaire: iPad Usage (N=160), TPACK (N=151), and demographics (N=147). Eight participants were interviewed after the survey. The results indicated TPACK and learning-centered pedagogy were necessary but insufficient …

Biology Laboratories At A Distance: A Case Study And Experiment Of Ecology And Evolution Labs With Community College Students, Beverly E. Ranney

Dissertations

Community colleges deliver more courses online; laboratory-based courses face challenges in how to do this. This study examined how ecology and evolution laboratories could effectively be delivered in an online biology community college course. Virtual simulations and hands-on, at-home kits were used in two groups. Results showed that students using the virtual simulations had higher learning gains and more positive perceptions towards their laboratory experiences than those students using athome kits. By evaluating learning gains on a pretest/posttest and utilizing interviews and focus groups, this research concluded that virtual simulations offered a superior learning experience for online learners. The results …

Using Mouse Models To Define How The P53 R72p Polymorphism Impacts The Adverse Effects Of Doxorubicin And Ionizing Radiation, Emily Dominguez

Dissertations and Theses (Open Access)

The single nucleotide polymorphism (SNP) at codon 72 of the tumor suppressor gene p53 codes for either an arginine (R) or proline (P) (p53 R72P). This SNP may impact how cells respond to genotoxic insult. Studies in cell culture and in tissues from mouse models of the SNP indicate that, in response to gentoxic treatment, the two variants may differentially induce apoptosis and expression of p53 target genes. In epidemiological studies, the P variant is associated with decreased cancer survival and increased risk of side-effects from genotoxic cancer treatment. Genotoxic therapy is still the mainstay of cancer treatment, and doxorubicin …

If This Heart Had A Mouth: A Forbidden Romance Narrated Through Mimesis: Poems, Julieta V. Corpus

Theses and Dissertations

If This Heart Had a Mouth consists of forty-two poems where love is the catalyst for a multitude of emotions, ranging from falling in love, to hopelessness, to a begrudging kind of acceptance at losing the beloved to somebody else. To create all forty-two poems, 23 written in Spanish, and 19 poems written in English, I employed the literary device called Mimesis which entails deriving an original poem from someone else's work.

To create each poem, I followed another poet’s original work, line by line. I imitated that poet’s rhythm through their use of meter. I counted the number of …

False Positives On Neuropsychological Measures Of Effort Among Bilingual Neurologically Intact Mexican Americans, Arnoldo Amador Jr.

Theses and Dissertations

The present study examines the performance of bilingual Mexican Americans on neuropsychological measures of effort in language and visual-perceptual formats. Optimal/suboptimal effort cutoff scores derived from monolingual English Speakers were used to test participants divided by language of administration and bilingual groupings based upon Spanish-English difference scores on the Woodcock Munoz Language Survey-Revised Picture Vocabulary subtest. Participants produced more false positives (misidentification of suboptimal effort) on the Reliable Digit Span, a language formatted measure, and similar rates of false positives on visual-perceptual effort measures: Test of Memory Malingering and the Dot Counting Test as compared to established rates using monolingual …

A Multi-Indexed Logistic Model For Time Series, Xiang Liu

Electronic Theses and Dissertations

In this thesis, we explore a multi-indexed logistic regression (MILR) model, with particular emphasis given to its application to time series. MILR includes simple logistic regression (SLR) as a special case, and the hope is that it will in some instances also produce significantly better results. To motivate the development of MILR, we consider its application to the analysis of both simulated sine wave data and stock data. We looked at well-studied SLR and its application in the analysis of time series data. Using a more sophisticated representation of sequential data, we then detail the implementation of MILR. We compare …

I developed a survey to assess dental hygienists’ awareness, attitudes, and their views regarding the new mid-level dental provider. The study was limited to licensed dental hygienists in Ohio. The study included a simple random sample of 400 of the 4100 dental hygienists in Ohio obtained by a systematic approach, …

Reconciling The Past In Octavia Butler's Kindred, Haley V. Manis

Electronic Theses and Dissertations

This thesis uses the observations of Nancy J. Peterson on historical wounds as a springboard to discuss Octavia Butler’s novel Kindred and its use of both white and black characters to reexamine the origins of the historical wounds and why they are so difficult to deal with even today. Other scholarly works will be used to further investigate the importance of each character in the story and what they mean to the wound itself. Specifically, Dana is analyzed alongside the other main characters: Rufus, Alice, and Kevin. Though Dana’s relationships with these characters, Kindred’s version of the past can be …
