Investigating Ph Banding Kinetics Of Chara Corallina In Alternating Light Conditions With Rectangular Pulse Voltammetry, Matthew C. Zandee

Masters Theses

Chara corallina is an important biological model due to its large internodal cells, the simple shape, and the wide range of techniques that can be used to study it. The alternating acidic and basic banding pattern of Chara corallina upon illumination has been studied and well described over the past several decades. However, much of this complex mechanism is not fully understood. Few studies have shown how the acidic and basic regions have responded in real time as lighting conditions change. Utilizing rectangular pulse voltammetry (RPV) and pH-sensitive carbon microelectrodes along the cell wall allows for a real time profile …

Coming Home: How Identity Plays A Role In Students Who Study Abroad In An Area That Is Representative Of Their Heritage, Mariana I. Naddaf

Masters Theses

Study abroad participation has more than tripled over the past two decades in the United States and has led to increased research efforts on topics such as the benefits of study abroad and the development of students who study abroad; however, little research exists on students who have heritage connections to the area in which they study abroad. In order to address this need within the field of higher education and study abroad, a hermeneutic phenomenological qualitative study was conducted to explore what factors, if any, affect changes in identity salience for students who study abroad in areas that are …

Internal Fault Location In Transformer Windings, Samir Yehya Abed-Alkareem Alzekri

Masters Theses

Power transformers are one of the most important components in electrical power systems. During their lifetime they are exposed to various electrical faults which are originated from transient overvoltages, electromagnetic forces due to over-currents, ageing, etc.

Internal winding faults are among the most common causes of transformer failure. Once a fault occurs, a fast an efficient method for its detection and location is required to avoid further delays in the network operation. This paper introduces a simple method for the location of internal winding faults. This method is based on time domain terminal measurements of wave propagation along the winding. …

Characterizing Groundwater Recharge And Streamflow Using Stable Isotopes Of Oxygen And Hydrogen, Chanse M. Ford

Masters Theses

Potential changes to climate and precipitation patterns from anthropogenic influences like global climate change could have an impact on Michigan’s groundwater resources. Indirectly this could have an effect on Michigan’s surface waters as well, since groundwater and surface waters are intimately linked to form one system.

This investigation utilized stable isotopes of oxygen and hydrogen found in precipitation, groundwater and surface waters to better understand the contribution of different types of precipitation to recharge of a shallow aquifer in Manistee National Forest, MI. The study also examines the contribution of this shallow groundwater to streamflow in the nearby White River. …

Scalable Parallelization Of A Markov Coalescent Genealogy Sampler, Philip E. Davis

Masters Theses

Coalescent genealogy samplers are effective tools for the study of population genetics. They are used to estimate the historical parameters of a population based upon the sampling of present-day genetic information. A popular approach employs Markov chain Monte Carlo (MCMC) methods. While effective, these methods are very computationally intensive, often taking weeks to run. Although attempts have been made to leverage parallelism in an effort to reduce runtimes, they have not resulted in scalable solutions. Due to the inherently sequential nature of MCMC methods, their performance has suffered diminishing returns when applied to large-scale computing clusters. In the interests of …

Examining The Effectiveness Of A Training Video On The Lmplementation And Lnterpretation Of A Functional Analysis, Alissa Anne Conway

Masters Theses

Functional behavior assessment (FBA), and more specifically functional analysis (FA), refer to structured assessment processes designed to identify the controlling variables for challenging behaviors across children, adolescents, and adults. The results from a functional analysis are used to match therapy techniques to unique causal variables for challenging behaviors and also to select more adaptive replacement behaviors that produce similar functions as the challenging behaviors. As functional analysis techniques, in all variations, have become more commonplace in applied behavior analysis (ABA), attention has turned to how to train practitioners to implement FAs, interpret the results, and use the FAs to inform …

State Estimation – New Models On Power Distribution Networks Based On Weighted Least Squares Method In Line Current Measurements, Hugo Vicente Barrera

Masters Theses

Calculation of Load Flow distribution is an important tool in Electrical Engineering that involves numerical analysis applied to Power Systems. State Estimation techniques have been developed and applied thoroughly mainly in the levels of generation and transmission. Research in the distribution level remains a challenge due to the intrinsic characteristics of the network. Introducing line current measurements in the state estimation process constitutes an additional issue due to distribution networks characteristics. In order to overcome these difficulties, it is necessary to develop mathematical models that simulate the behavior of those networks. The solution of the problem of state estimation by …

Registration And Segmentation Of Multimodality Images For Post Processing Of Skeleton In Preclinical Oncology Studies, Vineeth Radhakrishnan

Masters Theses

Advancements in medical imaging techniques provide biomedical researchers with quality anatomical and functional information inside preclinical subjects in the fields of cancer, osteopathic, cardiovascular, and neurodegenerative research. The throughput of the preclinical imaging studies is a critical factor which determines the pace of small animal medical research. The time involved in manual analysis of large amount of imaging data prior to data interpretation by the researcher, limits the number of studies in a time frame.

In the proposed solution, an automated image segmentation method was used to segment individual vertebrae in mice. Individual vertebrae of MOBY atlas were manually segmented …

The Effect Of Seasonal Fish Migration On Energy Budgets In Two Coastal Michigan Streams, Emily M. Dean

Masters Theses

Migratory fish are known to seasonally enter coastal stream systems but the magnitude of the effects these migrations have on stream energy budgets is not fully understood. The Laurentian Great Lakes have several introduced and native adfluvial fish, where only a few studies have investigated the impacts of their migration on energy budgets in Michigan coastal streams. We quantified the contribution of energy from Chinook salmon (Oncorhynchus tshawytscha) muscle and eggs, steelhead (Oncorhynchus mykiss) eggs, and larval white suckers (Catostomus commersonii) to coastal stream energy budgets. Energy densities and energy delivered to streams were estimated using bomb calorimetry and annual …

Comprehensive Evaluation Of The Effectiveness Of Pedestrian Countdown Signals On Road Users In Michigan, Richard Atta Boateng

Masters Theses

Pedestrian countdown signals (PCSs) are specifically designed to improve pedestrian safety at intersections. Installation of these devices may be with push buttons or without push buttons. Studies have shown that intersections where PCSs with push buttons have been installed have recorded reduction in pedestrian violation as well as reduction in the number of pedestrians trapped in the roadway. Studies have also shown that PCSs may be used by approaching drivers in the same way as other traffic signal anticipation devices such as green signal countdown (GSC). While other signal anticipation devices have been found to benefit drivers, a very limited …

Interaction Between Human Experience, Landscape , And Coffee Production In The Blue Mountain Region Of Jamaica, Shohei Yoshida

Masters Theses

In today's coffee industry, individual farmers’ identities are hardly visible from the products we buy. Each coffee farmer has different lifestyles and methods of coffee farming. Such information about farmers can make each cups of coffee potentially unique in consumers’ experience. However, there are barriers which make consumers blind from the identities of the farmers making their coffee. I will explain about the barriers, and introduce the way to make consumers associate individual farmers' identities with each cup of coffee they drink. This thesis mainly consists of two parts: a theoretical part and a poetry part. There is a small …

Developing Standard Procedures For Structural Aspects Of Slide-In Bridges In Accelerated Bridge Construction (Abc), Ozan Utku Ridvanoglu

Masters Theses

Slide-in bridge construction (SIBC) is a special method especially used to replace an existing bridge with the minimum duration road closure. In this method, new bridge superstructure is built next to the existing one and it is slid to its final position after demolishing the existing one. Applied implementations of SIBC show that several complications are experienced during bridge slide related with surface interaction. There is a need to evaluate the structural components of SIBC to develop suggestions. In this research, structural components of SIBC were investigated. The research dealt with completed SIBC implementations and numerical modelling of the slide …

A Geographic Distribution Analysis And Examination Of Social-Psychological Factors And Their Lmpact On Death Penalty Support In The United States, Katy Moharter

Masters Theses

Since the reinstatement of the death penalty in the United States in 1977, research has focused on shifting attitudes and waning public support for this institution. Support for the death penalty varies between different temporal, geographic, and demographic boundaries. Research also suggests that social-psychological factors such as attributional style and moral disengagement play a significant role in rationalization of death penalty support, as well as the intensity of the support. Aspects of moral disengagement serve as reliable predictors for death penalty support for a limited sample of participants, which this research intends to evaluate at a greater scale. This research …

The Perceptions Of Michigan Hunters Regarding Wolves (Canis Lupus) And The Ldea Of A Wolf-Hunt As A Management Option, Zachary A. Merrill

Masters Theses

Gray wolves (Canis lupus) are an important keystone species in mixed forest ecosystems throughout the Great Lakes region. Due to wolves being placed on the Endangered Species List in 1974, the wolf population of Michigan has increased from near extinction in 1974 to greater than 650 in 2013. The return of wolves to northern Michigan ecosystems has re-ignited complex debates regarding how humans and wolves should best coexist. Wildlife professionals have become increasingly aware of the importance of human response for sound wildlife management decisions. The most effective management plans require cooperation from all parties, including farmers, citizens, tourists, wildlife …

Slug Tests In Unconfined Aquifers, Rozkar Izzaddin Ismael

Strengthening Tier 1 Elementary Reading Within A Multi-Tiered System Of Support, Carla N. Osborn

Masters Theses

Training teachers about the foundational reading skills is an important step in creating students who are proficient readers. However, training is not enough. Teachers need support through instructional coaching. Even with coaching support, sustainability of these practices will be a challenge if systems are not in place throughout the district to support ongoing implementation. By combining the processes of creating a Multi-Tiered System of Support, reading training, and instructional coaching, sustainability of practices can be possible. Research does not currently exist as to whether the combination of these efforts has increased student achievement in reading at the elementary level. This …

Political Utopias Of The Renaissance: An Analysis Of Thomas More’S Utopia, Johann Valentinus Andreae’S Christianopolis, And James Harrington’S The Commonwealth Of Oceana, Brittany Page Brake

Masters Theses

Utopian works have entertained generations throughout history. Much like more recent genres including science-fiction novels or movies, utopian works stimulate the mind and ultimately cause its readers to question whether an author’s design of such a place, or society, is possible in the real world. While some may perceive the purpose of utopias to be completely fantasy-driven, there is a great deal of scholarly literature that dedicates itself to proving otherwise. More specifically, many scholars argue that utopias are serious and practical, ultimately aimed at re-shaping the entire political structure of a society.

This thesis aims to understand the more …

Royal Advice And Religious Authority In Smaragdus Of St. Mihiel's Via Regia:An Analysis And Critical Edition, Roland Black

Masters Theses

Around 813 CE, the Carolingian monk Smaragdus of St. Mihiel produced the first medieval moral guidebook for a king, entitled the Via regia. The text was most likely intended for Charlemagne’s sole surviving heir, Louis the Pious. Smaragdus incorporated passages from both the Old and New Testaments and provided exegesis meant to guide the king in correct moral behavior. The text asserted the critical importance of the king’s correct moral behavior, and offered a window into the Carolingian court as well as political and religious life at the turn of the ninth century. Presented here for the first time …

Extent Of Capillary Rise In Sands And Silts, Rachel Lynn Salim

Masters Theses

The values reported in literature for the height of capillary rise in fine sands, silts, and clays are contradictory. Most of the values were based on mathematical models, which used estimated rather than measured input data. This work measured capillary rise values in laboratory experiments in fine-grained sands and silts.

Two uniform sands with grains 0.35--0.7 mm in diameter and 0.3-0.6 mm in diameter, silt with an average grain size below 40 microns, and 0.35--0.7 mm sand coated with a water-repellant spray were carefully packed into two-inch diameter glass columns. These columns were placed into clear plastic tanks with water …

Becoming Self: A Jungian Approach To Paradise Lost, Geoffrey Kishbaugh

Masters Theses

When addressing Paradise Lost, the reader is not encountering static characters but is interacting with and being acted upon by highly symbolic manifestations of the primitive condition of humanity‟s collective psyche. In dealing with the figures of Christianity‟s mythos, John Milton creates a text that stimulates the collective unconscious of the reader and draws out the primordial expressions of the self—archetypal manifestations. Subsequently, these manifestations are projected back onto the figures within the text and the reader engages in a dynamic relationship with the poem as both the reader and the figures of Adam and Eve experience the process of …

Bsent From The Body, Present With The Lord: A Traditional Evangelical Critique Of Traditional Roman Catholic And Non-Traditional Evangelical Teachings Regarding Purgatory, Thomas Gentry

Masters Theses

Traditional Roman Catholic theology and certain non-traditional expressions of evangelical theology teach that Christians who die without realizing perfect holiness will enter into a postmortem state called purgatory for the purpose of preparing them to behold the beatific vision of God in heaven. The purpose of this work is to refute these teachings by proving that they are unbiblical. The procedure for doing is to first summarize the traditional Roman Catholic teaching of purgatory; second, present interpretations of select biblical and apocryphal texts related to purgatory from the pro-purgatory perspective, followed by a traditional evangelical response; third, present a four-fold …

The Value Of The Arts In Education, Thorin Teague

Masters Theses

Art is a subject that has no substitute, as the learning and production of art satisfies a uniquely human need to communicate and connect with other human beings. The marriage of art and society can (and should) be thought of as culture. This author intends to assert that the arts have a critical place in education and indeed human society itself, bringing ancillary benefits to bear on the subject without relying on them as the primary justification for the retention and even expansion of arts programs; education (which could in turn be thought of the dissemination of cultural knowledge) of …

The Gĩkũyũ Mũtũrĩrũ: Preserving A Piece Of Kenya's Agrarian Past Through Flute Music, Jennifer Larue

Masters Theses

The Agĩkũyũ people of Kenya are one of the largest people groups in Kenya. However, systematic repression of Gĩkũyũ culture led to many traditional elements being forgotten, put aside, if not lost completely. The mũtũrĩrũ, a bark flute used when herding and in certain ritual dances, was one such element. The mũtũrĩrũ was initially a temporary instrument, which evolved into more permanent bamboo versions. These may have between two and six finger holes. Another version, called a "spider web mũtũrĩrũ" has no finger holes but has a paper membrane over one end to create a buzzing timbre effect. Research was …

American Marten Denning Behavior In Michigan, Melissa J. Nichols

Masters Theses

Female American marten (Martes americana) produce litters of 1-5 kits between late March and early May. Kits remain with their mother for the duration of their first summer in a series of den structures. We located these den structures using radio-telemetry and placed remotetriggered cameras at the entrances to capture information on litter size, female activity patterns, and den visits by males and potential predators. From the summer of 2012 to the summer of 2014 we tracked 13 individual female marten (8 in the Lower Peninsula, 5 in the Upper Peninsula) with 17 litters to 75 unique den sites (60 …

“The Mirror Of Desire”: Britomart And Spenserian Perception In The Faerie Queene, Brandon J. Muri

Masters Theses

In modern usage, “love” and “justice” are terms used to describe universal standards of behavior even though the modern materialist worldview cannot account for such universal, abstract entities. Spenser’s Faerie Queene dramatizes the conceptual origin of these and similar terms in human experience; for, as C.S. Lewis has noted, Spenser’s poetry “Consists in giving an imagined body to the immaterial” (AL 322). Posing an answer to the question of whether these “imagined bodies” reflect an order of being transcending human experience, the romance narrative of Book III argues in the affirmative by demonstrating that universal standards such as love and …

Revision Of The Synechococcales (Cyanobacteria) Through Recognition Of Four Families Including Oculatellaceae Fam. Nov. And Trichocoleaceae Fam Nov. And Seven New Genera Containing 14 Species, Truc Mai

Masters Theses

A total of 48 strains of thin, filamentous cyanobacteria in the Synechococcales were studed by sequencing 16S rRNA, rpoC1, and rbcLX gene fragments. A subset of these were carefully characterized morphologically. Bayesian analysis of the 16S rRNA gene data in a large alignment of Synechococcales (345 OTU's) was in agreement with the phylogeny based on the rpoC1 gene for 59 OTU's. Both indicated that the large family-level grouping formerly classified as the Leptolyngbyaceae could be further divided into four family-level clades. Two of these family-level clades have been recognized previously as Leptolyngbyaceae and Prochlorotrichaceae. The Oculatellaceae fam. prov. and Trichocoleaceae …

A Photographic Study On College Student Sense Of Belonging, Sean Sheptoski

Masters Theses

Finding one’s sense of belonging has the capability to serve as the tipping point between success in college, and failure. According to McMillian and Chavis (1996), sense of belonging can be defined as the sense of community that members feel when they are in an environment and around other members. A way to achieve premier sense of belonging is by the creation of a caring, supportive and welcoming environment within the university. This study was designed to focus on the importance campus space plays in the creation of sense of belonging. Using a qualitative approach known as photovoice, the researcher …

Preschool Teacher's Use Of Praise: Comparing General, At-Risk, And Special Education Classrooms, Jessica Berlinghof

Masters Theses

The current study examined six preschool teachers' natural use of praise. Two of the teachers taught in general education classrooms, two taught in at-risk classrooms, and two taught in special education classrooms. Over 10 hours (approximately 100 minutes in each classroom) of direct behavioral observation of teachers' use of praise were conducted across classrooms. Results did not indicate that teachers' use of praise was statistically different based on classroom type (i.e., general, at-risk, and special education). However, special education teachers used twice as many praise statements compared to teachers in general education and at-risk classrooms and the effect sizes for …
