An Analysis Of Stable Isotopes From N-Alkanes Derived From Leaf Waxes In North America, Katherine T. Truong Ms.

Master's Theses

Leaf wax biomarkers are increasingly becoming a fundamental aspect of paleoclimate research. The strength of the relationship between their molecular and isotopic properties and environmental conditions is critical to their effectiveness in reconstructing past environments. To address the current lack of data pertaining to arid and semi-arid environments, soil and modern plant samples (grasses, trees, forbs, and shrubs) from sites in the western United States were analyzed to assess relationships between normal alkane molecular distribution, δD and δ¹³C and seasonal/annual climatic conditions in semi-arid ecosystems. The data show a stronger relationship between δD of leaf waxes (δD_{wax …}

Measuring And Improving Seniors' Access To Medical Facilities, Angelika Zygo

Master's Theses

The travel behaviors of older adults often shift as they retire, begin second careers and make residence location choices geared towards aging in place. Those who rely on transit as their primary mode of transportation can face many accessibility and connectivity challenges when traveling to basic amenities due to their unique travel behaviors and declining mobility with advanced age. First chapter of this thesis focuses on a subset of these travel behaviors through a literature review then evaluates the ability of public transportation to meet the specific mobility needs of older adults (defined in three ways: as those adults >65 …

Effects Of Art In Hiv Infected Population On Body Habitus Change: A Multilevel Meta-Analysis, Nusrat Nuireen Habib

Master's Theses

Importance: Different ART treatments to HIV patients has been shown to be effective in improving a variety of disease outcomes, including CD-4 cell count improvements and viral suppressions. In addition to these improvements, investigators are also interested to evaluate the association between ART treatments and the body habitus changes of the HIV patients. It is unclear that which body habitus change outcomes are more greatly associated with what type of ART treatments and how those effects could vary depending on context and sample characteristics.

Objective: To obtain overall effect sizes for the body habitus change outcome variables (weight, body mass …

The Properties Of Particleboard Using Bagasse, Sisal And Waste Carpet, Hanchi Zhu

Master's Theses

The demand for manufactured panels for construction, furniture and other applications place strains on the forestry industry leading to deforestation. Similarly, one component of the very large waste stream from construction and renovation is post consumer carpet. The post consumer carpet waste and widely available waste biomass streams can be used to produce panels sustainably. Laboratory scale panels were produced with several ratios of bagasse and carpet to deduce a reasonable formulation to produce M-2 grade particleboard. The selected formulation was used to produce several industrial prototype panels of 18mm thickness for independent testing. Statistical analysis was performed to assess …

Europe's Refugee Crisis: Right-Wing Populism And Mainstream Cooption In Germany And France, Jihan Abdalla

Master's Theses

In Europe’s biggest wave of refugees since World War II, over 1 million people fleeing protracted conflicts in Syria, Iraq and Afghanistan crossed the Mediterranean on unseaworthy boats in 2015 in a desperate bid to reach the continent. Rather than uniting to deal with the humanitarian situation, the European Union (EU), the world’s wealthiest and most integrated bloc, struggled to effectively manage the flow of refugees. Amid rising anti-immigration sentiment and nascent Euroscepticism, EU governments employed unilateral and security-driven responses aimed at limiting the number of refugees that would enter Europe. Europe’s Refugee Crisis, as it came to be known, …

The Validity Of Height As A Determinant Of Takeoff Distance To Hurdle One In Ncaa Division Iii Hurdlers 2017, Phillip Wiltshire

Master's Theses

The purpose of this study was to determine if the relationships between the height of a hurdler and the takeoff distance to the first hurdle for men and women as reported by Frye (2008) were valid for NCAA Division III 100 m and 110 m hurdlers. With no specific research reported to validate Frye’s data, it is unclear how the suggested takeoff distances were developed. It is also unclear whether hurdler height or another factor is the main determinant of takeoff distance for the high hurdlers. Participants in this study were three female 100 m hurdlers and four male 110 …

Araucaria In The Urban Landscape: A Novel Leaning Pattern And Evidence Of Cultivated Hybridization, Jason W. Johns

Master's Theses

Our understanding of the natural world is constantly evolving and strengthening as more observations are made and experiments are performed. For example, we understand that tree stems grow toward the light (positive phototropism; Darwin 1880, Loehle 1986, Christie et al. 2013) and against gravity (negative gravitropism; Knight 1806, Hashiguchi et al. 2013). We also know that plants respond to mechanical stimulus and perturbation (thigmotropism; Braam 2005). Genes and their resulting proteins have been described to uncover some of the mechanisms for these environmental responses, but relatively speaking, we have just scratched the surface (Wyatt et al. 2013). While the discovery …

Diet Induced Obesity Alters Muscle Spindle Afferent Function In Adult Mice, Lubayna Elahi

Master's Theses

Individuals with obesity are more likely to fall and exhibit balance instability. The reason for this is likely multifactorial, but there is some evidence that sensory function is impaired during obesity. We tested the hypothesis that muscle proprioceptor function is compromised in a mouse model of diet induced obesity. We used an in vitro muscle-nerve preparation to record muscle spindle afferent responses to physiological stretch and sinusoidal vibration. We compared the responses of mice on a control diet (10% kcal fat) with those eating a high fat diet (60% kcal fat) alone or in combination with either aspirin (120mg/kg/day in …

“Creating A New Mythos”: Reassessing Race Standards And Latina/O Students, Margarita Vizcarra

Master's Theses

This research will focus on the race and ethnicity categories used to classify people in the United States in relation to school age students. The Office of Management and Budget (OMB) first standardized federal race and ethnicity categories in 1977 in order to enforce compliance with civil rights laws. In 1997 revisions were made to these standards due to increasing criticism by the public, advocacy groups, and government agencies (Williams, 2006). The 1977 decision by the OMB designated the category of Hispanic, or Latino, as an ethnicity rather than a race which was once again upheld in the 1997 update. …

The Role Of Phage Trnas In The Evolution Of Codon Usage Biases In Giant Pseudomonas Phage Phikz And El, Stephanie Steidel

Master's Theses

As the most abundant and diverse biological agents in the biosphere phage have significant roles in microbial ecology, acting both as lethal bacterial parasites and vehicles of horizontal gene transfer. Phage/host coevolution drives optimization of phage codon usage for use of host translational machinery, thus lowered correspondence between phage and host codon usage reduces viral fitness. Some phage may partially bypass host translational selection on their codon usage by encoding their own tRNAs, although the effects of these tRNAs on phage codon usage and translation has not been well examined. This work explores the influence of phage encoded tRNAs on …

Defining The Roles Of The Lipoic Acid Ligases In Promoting Staphylococcus Aureus Metabolic Homeostasis And Virulence, Irina Laczkovich

Master's Theses

Staphylococcus aureus is a major human pathogen known to cause disease in a wide range of tissues. In order to thrive in such diverse environments, S. aureus uses multiple adaptive traits such as trace metal/nutrient acquisition, shifts in metabolic activity, and expression of detoxification systems, all of which allow the bacterium to proliferate and survive in nutritionally deficient and inhospitable environments.

One essential metabolite used by S. aureus is lipoic acid, a cofactor of enzyme complexes used in aerobic metabolism, fatty acid biosynthesis, glycine detoxification, and maintenance of redox homeostasis. Prior studies in the lab used a genetic approach to …

Depressive Symptoms, Neuropsychological Functioning, And Self-Management In Youth With Spina Bifida: Direct, Mediating, And Reciprocal Pathways, Alexa Stern

Master's Theses

Although successful self-management of health care responsibilities is critical to meeting the developmental demands associated with the transition to adulthood in youth with spina bifida (SB), research on individual factors impacting self-management in this population is sparse. Given the increased risk for cognitive deficits and development of depressive symptoms in this population, this study utilized a longitudinal, multi-method, multi-informant design to examine two pathways through which depressive symptoms and neuropsychological dysfunction may be associated with medical autonomy and adherence in youth with SB.

Bootstrapped mediation analyses revealed that teacher-reported depressive symptoms significantly mediated the respective relationships between attention and working …

Glaucous-Winged Gull Predation On Chicken Eggs Treated With A Uv-Blocking Agent, Athena T. Smith

Master's Theses

Egg cannibalism plays a major role in the life histories of Glaucous-winged Gulls (Larus glaucescens) breeding at Protection Island, Washington. Gulls, along with other birds, visualize reflected ultraviolet (UV) light and I wondered if reflected UV light plays a role in determining which eggs are selected for cannibalization. Motivated by studies showing that tree-nesting bird eggs coated with a UV-blocking agent were less subject to predation than control eggs, I tested whether ground-nesting Glaucous-winged Gulls would preferentially predate control chicken eggs over those coated with a UV-blocking agent. Early during five mornings I formed artificial nests at randomly-determined …

Revisiting The Date Of Stratum V At 'Araq El-'Emir, Jordan, Daniel A. Ulvoczky

Master's Theses

Problem

Paul W. Lapp excavated at ‘Araq al-‘Emir and dated Stratum V to Iron Age I with an occupation gap before later periods. Later findings by scholars suggested a later date for this stratum, but no one has reviewed the original material in order to complete this. This study revisited the date of Stratum V using Lapp’s original sherds and field notes.

Method

The original sherds and field notes were borrowed from Nancy L. Lapp at Pittsburgh Theological Seminary. The data in the field notes was cross-examined with the sherds to identify the relevant sherds. A comparative analysis was conducted …

The Relationship Of Law And Grace In The Hermeneutics Of New Covenant Theology, Carlos J. Cruz Pacheco

Master's Theses

Problem

This thesis evaluates the offer by New Covenant Theology of an interpretation of salvation history that stands in criticism of interpretations offered by Covenant Theology and Dispensationalism. Does New Covenant Theology demonstrate a distinctive view of the law-grace relationship that brings new perspectives on important theological and hermeneutical issues such as the relationship between the Old and New Testaments, and the Sabbath. Are New Covenant theologians correct in their claim that their system presents the best interpretation of salvation history, and of the law-grace relationship?

Purpose

The purpose of this investigation is to evaluate New Covenant Theology’s hermeneutics by …

Sin And Its Place In The Experience Of Suffering: Presenting The Basis For A Sound Theodicy, Roman Wiens

Master's Theses

Topic

One of the most significant issues in theism is the obvious existence of evil and suffering. Thus many philosophers (especially Atheists) propose this fact alone negates the existence of an all-loving, omnipotent, and caring God. This attacks both the integrity of God and the coherence of the scriptural accounts. In response, theologians around the world proposed theodicies to show that the existence of a God, as portrayed in the Bible, is coherent with suffering in this world.

Purpose

The different approaches to this problem are categorized in four categories, outlined, and evaluated in one chapter about the most noteworthy …

The Hermeneutical Frameworks Of Fernando Canale And Fritz Guy: Sola And Prima Scriptura And The Science-Theology Relationship, Ryan Nicholas Claude Brousson

Master's Theses

This thesis presents research on the hermeneutical frameworks of sola and prima Scriptura and how they affect the science-theology relationship. It specifically focuses on the writings of Fernando Canale and Fritz Guy who hold opposing views on both sola and prima Scriptura and the relationship between science and theology. Canale argues for a sola Scriptura framework with science governed by theology, whereas Guy argues for a prima Scriptura framework with science and theology working independently of each other.

This thesis begins with a brief historical overview of the issues and then moves into describing Canale’s and Guy’s views. It ends …

Intensity Structure: An Exegetical Approach To Pharaoh's Heart Hardening, Anthony Joel Rodriguez

Master's Theses

Problem

How can the LORD ascribe sin to humans if He Himself hardens their hearts in order to resist His will? This investigation was directed to find a tentative answer to the paradoxical story of the hardening of Pharaoh’s heart. Various approaches to this phenomenon of hardening were explored. Among these views the most common are: (1) the LORD hardened Pharaoh’s heart, (2) Pharaoh hardened his own heart, and (3) the LORD and Pharaoh played a part in the process of the hardening. None of these approaches were found to be fully satisfactory, and no scholarly consensus has emerged in …

The Study Of The Development Of Negation In Bilingual Spanish/English And Monolingual English Speakers, Isabel Cristina Verduzco

Master's Theses

Problem

Negation is one of the first concepts learned early during childhood and one of the most important ones for communication. Current studies focus on how negation is developed universally in each specific language and how it is governed by patterns of acquisition, however, there are factors that may affect this process. How does learning two languages simultaneously affect the normal development of negation? Analyzing how the exposure to two different languages affects the normal development of negation is important for understanding how bilingualism influences normal language development. This study is also important for the analysis of speech and language …

A Comparison Of Vocal Health, Hygiene, And Perceptions In Student Teachers, Voice Music Majors, And Speech-Language Pathology Majors: A Preliminary Study, Kenreah Lavaughn Brown

Master's Theses

Problem

There are many college/university students studying to become teachers, professional singers, and speech-language pathologists. Yet, despite research available on the risk of developing voice disorders in these areas of study, very little was found on such individuals while in the college setting. This is particularly true for speech-language pathologists who have limited research available overall.

Method

Nineteen students between the ages of 18- 43 years old, completed pre-and-post-testing of the Glottal Function Index (GFI), Voice Hygiene Questionnaire (VHQ), and the objective measures (maximum phonational frequency range, sustained phonation, jitter, and shimmer).

Results

The chi-square of independence results showed that …

Study Of The Ability To Detect Humor In Visual Images By 2-5 Year Olds, Sonovia Latoya Mcfall

Master's Theses

Problem

Understanding the impact that humor can have as a form of therapy has been studied mostly in relation to mental and spiritual healing. As a result, little focus has been given to understanding the types of humor and how one’s understanding of and appreciation for types of humor develop over time. Gaining an understanding of humor development is important due to discoveries that the use of humor is a great intervention tool when working with children. Nevertheless, the use of pictures (with humor) is often used within speech therapy sessions, but seldom used correctly due to the lack of …

Theory Of Mind And Negation, Jasmine Buckins

Master's Theses

Problem

There is an extensive amount of research on theory of mind, which is the ability to attribute mental states (e.g., beliefs, intents, desires, knowledge, etc.) to oneself and others and to comprehend that others have beliefs, desires, intentions and perspectives that may be different from one’s own. Some researchers have investigated the potential prerequisites or developmental milestones that may be required in order for a theory of mind to be developed in young children. Some researchers have concluded that certain factors play a role in theory of mind development. These factors include environmental, cognitive and linguistic components. However, in …

An Evaluation Of The Definition Of Exhaustive Foreknowledge In The Writings Of Richard Rice, Dennis E. Akawobsa

Master's Theses

Problem

This thesis addresses the conflict of interpretation between Richard Rice’s model of God’s exhaustive knowledge of the future as a realm of possibilities and the generally accepted traditional model of God’s exhaustive definite knowledge of the future. In harmony with the traditional perspective, Richard Rice has affirmed God’s exhaustive knowledge of the past and the present. However, in contrast to the traditional perspective, he has denied God’s exhaustive definite foreknowledge of future free choices. According to Rice, God can know everything there is to know. This implies that, on one hand, the future does not yet exist, so God …

Grief Management: The Divine And The Human Factor, Ransom Khanye

Master's Theses

Problem

When someone is bereaved, friends, comforters and sympathisers at times try to make sense of the situation. Some people theoretically deal with issues surrounding the death of someone and grief of the surviving ones without any personal experience of these events. Hypothetical and imaginative reasoning in comforting other people is insufficient for making a real impact and a significant and lasting difference to the bereaved. The current study was to try to identify the most effective way to help and console people who have lost their loved ones.

Method

The process of collecting data for this thesis was online …
