Origin Of High Levels Of Ammonium In Groundwater, Ottawa County, Michigan, Derrick Lingle

Masters Theses

Groundwater from wells located in and around Hemlock Crossing Park in Ottawa County, Michigan has elevated levels of ammonium. High ammonium concentrations in potable water wells are a common indicator of anthropogenic impact, such as landfill leachate or agricultural activity. Ammonium can also occur in groundwater through the decay of natural organic material. Along with the retrieval of a complete glacial sediment core via rotasonic drilling, numerous chemical and isotopic parameters were used to determine the source of ammonium in the impacted aquifer.

Buried organic material, deposited during the Athens subepisode interglacial period, is in contact with groundwater containing elevated …

Recovering The Saumurois: Lay Patronage To Saint-Florent Of Saumur, Ca. 950-1150, Adam C. Matthews

Masters Theses

In the mid-tenth century, the lay powers of the Loire valley established the abbey of Saint-Florent at Saumur with the local aristocracy welcoming the monks and forming spiritual and economic relationships through acts of patronage. The brothers remembered gifts of property, grants of rights, and exemptions in charters which were ultimately collected into the abbey's first cartulary, the Livre Noir. Despite this wealth of sources, historians have paid only cursory attention to Saint-Florent in recent scholarship. The present study incorporates the abbey's charter sources into broader debates concerning society in eleventh-century France. The use of case studies provides insight …

Utilizing Persistent Scatterer Interferometry To Investigate The Nature And Factors Controlling Nile Delta Subsidence, El Hachemi Yousef Bouali

Masters Theses

The Nile Delta in Egypt is being threatened by two continuous and relatively slow hazards: encroachment from the Mediterranean Sea as sea levels rise and land subsidence of the delta itself. The magnitude of sea level rise has been actively monitored, while the subsidence of the Nile Delta has not been adequately quantified spatially and temporally. Instead, all previous studies have either focused on measuring average Holocene subsidence rates or modern subsidence rates on local scales (point- or city-scale).

The overall study objective is three-fold: (1) to measure and map the spatial variations in subsidence rates across the entire Nile …

Still Siblings: The Perceived Importance Of Sibling Relationships For Foster Children, Jessica A. Church

Masters Theses

This research was conducted to answer the question “Do children who are perceived to have strong relationships with siblings and more access to their siblings have fewer problems adjusting to their foster care placement as observed by child welfare professionals?” This qualitative research project was completed through semi-structured interviews with professionals who work with children in foster care in a variety of ways (and may have worked with children in more than one way during their career in child welfare), such as foster care workers, counselors, and sibling visitation supervisors. The snowball sampling method was used in this research. These …

Results from simulated delivery areas identified interesting tradeoffs when comparing densely populated areas to sparsely populated areas. In addition, recommendations for order …

Labeling Research Deviant: A Comparative Analysis Of Federal Ad Hoc Commissions On Human Subject Research, Brian W. Rossana

Masters Theses

A review of the literature suggests there is still reason for concern due to the nature of deviant research in the past and the continued existence of ambiguous guidelines in particular organizational contexts. Federal ad hoc commissions have been a prominent environment where the absorption of the social reaction to deviant events and discussions regarding bioethics has transpired. The goal then was to ask what conditions of commissions lead to the presence of a research deviant? A convenience sample of nine U.S. federal ad hoc commissions was performed utilizing a method known as crisp-set Qualitative Comparative Analysis (csQCA). The results …

Stratigraphic Controls On Diagenetic Pathways In The St. Peter Sandstone, Michigan Basin, Stephen A. Zdan

Masters Theses

The Middle Ordovician St. Peter Sandstone in the Michigan Basin is a target for hydrocarbon exploration/production, and carbon sequestration and geologic storage. The St. Peter is predominantly a marine sandstone with four dominant lithofacies. The uppermost facies contains zones of porosity and good reservoir quality. Because of the mostly uniform detrital composition, diagenesis must play a leading role in reservoir quality development. This study tests stratigraphic controls on diagenesis and reservoir quality development. The distribution of diagenetic regimes is believed to result from depositional setting and related geologic processes, including variations in sediment accumulation rate. Early carbonate cements preserve pre-compaction …

Between The Man And Beast: Reactions To Evolutionary Science In Alfred, Lord Tennyson's Idylls Of The King And T. H. White's The Once And Future King, Mary Feldman

Masters Theses

The development and popular acceptance of evolutionary theory in the nineteenth century, of which Charles Darwin was perhaps the leading voice, produced perhaps the greatest cultural cataclysm of the Modern age. It held theological and philosophical implications beyond the scientific realm, profoundly impacting the humanities as well as science. The Arthurian legend, a story that has been told and retold for centuries before and after Darwin, offers us a unique opportunity to examine how a preexisting story was radically altered in the light of evolution. Alfred, Lord Tennyson's Idylls of the King and T. H. White's The Once and Future …

The Effects Of The Temporal Placement Of Feedback On Performance And Skill Acquisition Of A Medical Data Entry Task, Nathan Bechtel

Participants were randomly assigned to one of three groups, which differed only in the phase order utilized. Participants performed a data entry task intended to replicate thejob of …

Response To Intervention: A District’S And School’S Implementation, Michelle L. Carter

Masters Theses

This paper demonstrates how the Response to Intervention (RTI) system was implemented in one district and school, and may serve as a model for others to follow. The RTI framework has the capacity to push participating schools to examine the quality of instruction and, more importantly, to use ongoing student assessments to determine the instruction each student needs to be academically successful. The leadership and policy literature as well as legislative and other reforms such as RTI, systematic assessment, instructional strategies, is reviewed. The results of the RTI implementation at the district and building level are shared. For example, in …

Teaching World Music In An Elementary Setting: Effective Teaching Strategies And Classroom Materials, Calyna Mc Allister

Masters Theses

The world we live in today is increasingly a global society. As such, the various cultures of the world come into contact with one another more often. Students today need to have experiences with different cultures in order to participate effectively in this globally minded world. An excellent way to expose children to these cultures is through the use of world music in the general music classroom. The need for world music from a music education standpoint has been addressed over the past few decades. However, little has been done to address the teaching methods associated with world music or …

Identification Of Actin Cytoskeletal Protein Interactions With The Fission Yeast Scaffold, Mid1, Marian Testori

Masters Theses

Cancer is a disease of uncontrolled cell division. Cell division in eukaryotic cells occurs by the formation of a contractile ring, predominantly composed of filamentous actin (F-actin). During mitosis, actin filaments polymerize to form rings at the medial plane of the cell that constrict causing the cell membrane to pinch and divide. Proteins that regulate this process are essential because dysregulation can lead to uninhibited cell growth and division. In fission yeast, the protein Mid1 functions as a scaffold to recruit regulatory proteins required for actin filament formation and simultaneously anchors the contractile ring at the cell division site. The …

Using Normative Messages And Incentives To Improve Organizational Performance, Anna L. Conard

Masters Theses

While social norms have been a popular area of study among social psychologists, they have yet to receive much consideration from an Organizational Behavior Management (OBM) standpoint. Much of OBM research has focused on consequences and the utilization of incentives to improve organizational performance. Such research has shown incentive systems to have sustaining, long-term effects on behaviors. The purpose of the current study was to evaluate the impact of normative messages and lottery incentives on organizational performance. Participants were randomly assigned to one of four experimental conditions: a) Standard Message with Lottery Incentive, b) Standard Message without Lottery Incentive, c) …

Surface Complexation Modeling Of Cr(Vi) Absorption On Mineral Assemblages, Ann M. Gilchrist

Masters Theses

Hexavalent chromium (Cr(VI)) is a waste product of many anthropogenic processes. Because it is highly mobile, the improper disposal of Cr(VI) has caused widespread contamination. Because reduction and adsorption reactions may reduce the bioavailability and mobility of Cr(VI) in environmental systems, a better understanding of Cr(VI) adsorption behavior will improve remediation efforts.

Subsurfaces and soils are heterogeneous, however most studies focus on single sorbate/sorbent interactions to develop surface complexation models (SCM) for prediction of heavy metal adsorption. Theoretically, combining the SCMsdeveloped for single sorbate/sorbent systems should yield accurate predictions of adsorption in more complex systems (i.e., the component additivity approach …

Study Of Feasability For Phase Difference Extraction Using Software Defined Radio In Location Analysis, Paul Miller

Masters Theses

Here is a method for using the phase of an HF radio signal for use in location analysis. This computation is implemented in a software defined radio processing block in the GNU Radio environment. The signals analyzed are received by an Ettus Research USRP SDR. We created a phase analysis system called WMU Rootsync, which compares the roots of a received signal to the roots of a generated reference signal for the phase analysis. This research describes a prototype method for phase analysis only. Future projects may use these ideas differently than presented here. We intend for future projects to …

Disease Ecology Of A Microsporidian Parasite And Its Effects On Mottled Sculpin, Jared Joseph Homola

Masters Theses

Infectious disease can influence organisms at all levels of ecological organization, from individuals to ecosystems. Likewise, the ecosystems where pathogens exist directly influence their success. Recent theoretical studies have tied disease prevalence to biotic factors such as genetic diversity, biodiversity, and host behavior, and abiotic factors that include temperature and increased nutrient concentrations. Parasites included in the phylum Microspora are increasingly recognized for being ubiquitous in nature, although their ecological roles are generally unknown. This study examined several environmental, community, and host-related metrics to compare the biotic and abiotic aspects of 16 small streams; 6 with mottled sculpin (Cottus …

Mapping Of Uml Diagrams To Extended Petri Nets For Formal Verification, Byron Devries

Masters Theses

PURPOSE: UML Statechart Diagrams are the industry standard for modeling dynamic aspects of system behavior. However, other behavioral models, such as extended Petri Nets, are significantly easier to analyze formally. This research project creates methods of converting previously unconvertible features of UML Statechart Diagrams to extended Petri Nets to allow for additional analysis of UML Statechart Diagrams. PROCEDURES: Algorithms are introduced that convert specific UML Statechart Diagrams to a novel behavioral construct, Swim Lane Petri Nets, and subsequently to extended Petri Nets. Algorithms are also introduced to convert both Swim Lane Petri Nets and extended Petri Nets to the PROcess …

This first chapter of this thesis considers the various aspects of the kingdom in relation to God's coming judgment and the coming messiah who is often seen as the one bringing judgment and setting up the kingdom of God. The second chapter elaborates upon Jesus' teachings about the apocalyptic kingdom of God and compares and contrasts them with the teachings of the kingdom in His day as understood through the Second Temple …

An Exploration Of The Impact That Postmodernism Has On Competition In Sport, Shara Crow

Masters Theses

The purpose of this study is to explore the impact that postmodernism has on competition in sport. Previous studies compartmentalized social thought and competition in sport. This study appreciates that the two are connected, and it is through this connectedness that the impact emerges. By describing, finding, and analyzing relationships through text as well as notating text iteratively, it was found through a postmodernist critical awareness to meta-narratives that sport is expressed in two main themes: (a) identity (b) and hierarchy/authority. Moreover, both of these themes are interrelated to social interaction. These findings indicate that social interpretation impacts the complex …

A Preliminary Study Of The Articulatory And Acoustic Features Of Forward And Backward Tone Placement In Singing, Krista Wyllys

Masters Theses

A variety of terms exist for describing tone quality in singing, and voice scientists, voice therapists, teachers of singing, and students of singing use different terms to describe the same sound. One aspect of tone quality is tone placement. Teachers of singing often rely on imagery and imitation to elicit correct tone placement from students of singing. More concrete data about what produces forward and backward tone placement could supplement singing teachers’ current practice of using imagery and imitation to elicit a desirable tone quality. This study examined forward and backward tone placement to determine the articulatory gestures and acoustic …

A Quantitative Analysis Of Collegiate Athletic Involvement And Academic Achievement Among Sport Management Students, Christopher Amos

Masters Theses

Within the last several decades, more attention has been focused on the academic success of college athletes. It has been documented from several studies that high school athletes perform better academically than their non-athlete peers (American Sports Institute, 1995; Brand, 2007; Dilley-Knoles, Burnett, & Peak, 2010; Foltz, 1992; Fox, Barr-Anderson, Neumark-Sztainer, & Wall, 2010; Slear, 2005). However, at the collegiate level, this heightened academic achievement trend among student-athletes is not so clear. Lapchick often releases data regarding graduation rates among a select group of highly achieving teams in certain sports but not much exists in the way of a comparison …

Use Of A Specific Alpha7 Nicotinic Acetylcholine Receptor Agonist Can Prevent Loss Of Retinal Ganglion Cells In An In Vivo Rat Glaucoma Model, David Mata

Masters Theses

Acetylcholine (ACh) has been shown to have a neuroprotective effect against glutamate-induced excitotoxicity in cultured retinal ganglion cells (RGCs) through activation of α7 nicotinic ACh receptors (nAChRs). In this study, the neuroprotective effects of the α7 nAChR agonist, PNU-282987, were investigated using an in vivo model of glaucoma in adult Long Evans rats. Hypertonic saline injections were used to induce a glaucoma model. After one month, retinas were removed, flat mounted, fixed and labeled with an antibody against Thy 1.1 to label RGCs and fluorescently tagged for visualization. Eye drop application of PNU-282987 resulted in neuroprotection against RGC loss in …

A New Kind Of National: Modified String Quartet Practices In Post-Soviet Eurasia, Adam Taylor Lenz

Masters Theses

This thesis examines the practices of string quartet modification implemented by three post-Soviet Eurasian composers: Franghiz Ali-Zadeh (Azerbaijan), Vache Sharafyan (Armenia), and Dmitri Yanov-Yanovsky (Uzbekistan). After an introduction to the geography of the region and the biographies of the composers, their works containing modified string quartet configurations are examined within three distinct modification practices. These practices consist of the addition of outside instruments, the addition of electronic components, and the alteration of performance practice. The evaluation of these techniques is carried out through musical analysis and examination of cultural context. After each work has been examined, the body of works …

Explicit Teacher-Implemented Phoneme Awareness Instruction: Preschool Effects, Heather M. Osterhouse

Masters Theses

The purpose of the current study was to investigate the impact of explicit, concentrated, teacher-implemented phonological awareness instruction for ―at risk‖ 4- year-olds. Early childhood educators were trained to implement a 10-week program delivered for 20-minute sessions, four times a week, in their classrooms. The program focused on phonological awareness beginning at the level of letter-sound knowledge and advancing to blending and segmenting constituent phonemes in words. Pre- to post-treatment comparisons of phonological awareness and letter knowledge skills indicated that children in the experimental group made significant gains in comparison to the control group in phoneme blending and letter knowledge. …

Data Storage Alternatives For A Gridded Crop Disease Risk Forecasting System, Paul J. Roehsner

Masters Theses

Three separate storage technologies able to serve gridded data were selected for comparison of performance in terms of providing speed and expandability to a crop disease forecasting system. The three storage technologies chosen were PostgreSQL (a relational database management system), MongoDB (NoSQL system), and netCDF files. Speed tests were performed for each by running two different crop disease risk forecasting models requiring data of different spatiotemporal resolutions. Multiple trials were done using different storage hardware. Systems were then qualitatively compared for expandability by noting the process involved in adding successive crop disease forecasting models.

It was found that due to …
