This study investigates the factors which affect the safety of non-motorized transportation within the influence area of intersections to enhance development of safety performance functions (SPFs). The scope of this study is limited to the four Michigan cities of Ann Arbor, East Lansing, Flint and Grand Rapids. Due to the current lack of research regarding the appropriate size of the influence area, this study investigates the distance of crashes relative to the center of 148 intersections to identify the most probable area of influence for different crash types. For motorized and non-motorized crashes, 240 ft. and 137 ft. are proposed, …

Investigation Of The Definitive Age Of Freshwater Decapod Crustaceans, Orconectes Propinquus And Procambarus Clarkii, Via Growth Bands In The Calcified Regions Of The Eyestalk And Gastric Mill, Jayson L. Clore

Masters Theses

A preliminary study that utilized the calcified regions of the eyestalks and gastric mills of decapod crustaceans for chronological age determination. The procedure is based on the traditional method for growth analysis of concentric growth bands in otoliths, shells, and genital plates. Transverse cross sections of the eyestalks and prepyloric, pyloric, and zygocardiac ossicles of the gastric mills of Orconectes propinquus and Procambarus clarkii crayfish showed the presence of alternating dark and light growth bands. These growth bands were recorded as a finer secondary series of growth bands found within the broader primary growth bands. Size modal comparisons showed that …

Owning Our Food System: Urban Community Gardening And Local Food Movements, Paige A. Edwards

Masters Theses

Food is a means of examining culture, including identity, autonomy and power. It creates relationships and memories between people via shared connections. Through food, I explore local food movements and urban community gardening.

We both ingest and produce garden-grown foods. This movement is often described as simple nostalgia. I suggest that it is a response against heavily processed foods within a system reliant on mass produced food. This desire for ownership pushes community gardens and other counter-hegemonic spaces forward in their goals of using social practice to challenge the established food industry and take control within their own lives.

Is The Nfl Responsible For Concussions Sustained By Players?, Lindsey Reid

Masters Theses

National Football League (NFL) players have sustained concussions while playing football (Casson & Viano, 2010). There is a growing controversy between NFL players, their immediate families, and the league regarding alleged claims that management should be held responsible for the physical deterioration of former players including compensatory damages for suffering. Family members of current and past NFL players claim league officials provided inadequate education regarding risks associated with playing professional football. Former players are experiencing health issues such as dementia, early Alzheimer's, chronic traumatic encephalopathy (CTE), trouble concentrating and inability to work; in some cases these debilitating life-changing events have …

Idealism And Pragmatism In The Rhetoric Of John Boehner: A Weaverian Analysis Of Congressional Discourse, Cody Hawley

Masters Theses

American political rhetoric is characterized by a synthesis of contradictory idealistic and pragmatic elements, both of which are necessary if there is to be convincing persuasion. The way in which politicians rhetorically approach this dichotomy is significant, however, current studies on the topic are limited to presidential discourse. There is little research on this topic in other settings such the United States House of Representatives. This criticism analyzes John Boehner's congressional rhetoric in the idealistic-pragmatic dichotomy. The critical method utilized is Richard Weaver's four forms of argument-genus, similitude, consequence, and circumstance. Eight speeches of John Boehner, four from his position …

Combined Effects Of Mdma And Ethanol On Locomotor Activity And Place Conditioning In Male And Female Adolescent Sprague-Dawley Rats, Keli A. Herr

Masters Theses

MDMA, ("Ecstasy") is commonly abused in combination with ethanol (EtOH). Relatively few preclinical studies have investigated sex differences in animal models of polysubstance use. The current study employed a conditioned place preference (CPP) procedure to assess the behavioral effects of the co-administration ofMDMA /EtOH in 32 male and 32 female adolescent Sprague-Dawley rats. Following a 15 min habituation trial, eight 30-min conditioning trials were conducted in two- compartment chambers with different environmental cues. Before each drug conditioning trials, rats were administered intraperitoneal (i.p.) injections of MDMA(6.6 mg/kg), EtOH (1.5 g/kg), MDMA (6.6 mg/kg) and EtOH (1.5 g/kg), or saline. Prior …

Re-Inscribing History, Yoonkyung Kim

Masters Theses

Most images and informational data from historical records and databases remain unseen because there is a massive over-saturation of visual material. This material has not been thoroughly investigated or understood. Historical archives offer opportunities to discover stories that reposition history in more intimate terms. I explore what remains unseen by revealing new routes that these "facts" can take.

Exploring the boundaries between the public and the personal, I visit archival documents, public databases, and historical collections. Fascinated by their stories' multifaceted nature, I critically examine these primary sources that nourish generations of new histories.

My intention is to redefine our …

Towards An Integrated Personhood Through Suffering: The Disparate Ideologies Of Freud, Maritain, And Aquinas And The Power Of Analogy In Graham Greene's The Power And The Glory, Dana Sarchet

Masters Theses

Freud, Maritain, and Aquinas have greatly influenced the literature of Graham Greene, and Greene's The Power and the Glory is no exception. As both Freud and Greene attest to the irrevocable influence of childhood on adulthood, we must read Luis, the primary child character in The Power and the Glory, in light of the characters who impact his transition into his adult life. But these characters reflect yet another thread in Greene's perspective of personhood; studying Catholicism at least four years before writing Catholic fiction, Greene was also greatly influenced by the theological thought of Aquinas and Maritain, and this …

Saving Jazz: Applied Ethnomusicology And America's Classical Music, Christopher Long

Masters Theses

In his 2009 article, Can Jazz Be Saved?, Wall Street Journal columnist Terry Teachout asserted that the American audience for jazz music performances was both shrinking and aging. Saving Jazz: Applied Ethnomusicology and America's Classical Music explores this jazz audience problem and finds that over the last thirty years the overall American audience for live jazz performances has not shrunk as has been widely reported, but is essentially unchanged in size. During that same period, though, there is no question that the median age of the audience has changed dramatically. Data collected by the National Endowment for the Arts and …

Managing Dispersed Recreation In The Allegheny National Forest, Anne Santa Maria

Masters Theses

In the Allegheny National Forest, an unregulated dispersed camping policy has led to significant impacts to the natural environment. This study used data gathered from visitor surveys, interviews with managers, and environmental conditions of campsites to recommend management actions for campsites along seven roads in the National Forest. The seven road areas fell into two categories. Primitive recreation was more common in some areas and solitude was more highly valued by campers. Other areas had more frequent visitor use, motorized camping, and solitude was less important to campers. These factors influenced management recommendations, which include designing and constructing campsites to …

A Quantitative Tool For Identifying The Epileptogenic Zone Using Network Connectivity Analysis, James Michael Gurisko

Masters Theses

Approximately one-third of patients diagnosed with focal epilepsy do not respond to medication and may be candidates for surgery to remove epileptogenic tissue known as the epileptogenic zone. A detailed pre-surgical evaluation is required and often includes invasive video electroencephalographic monitoring (IVEM) using intracranial surface and depth electrodes, and a camera. The resulting large pools of electrocorticorticographic (ECoG) data are manually analyzed by an expert epileptologist to determine epileptic events. The process is time consuming and prone to human error. This thesis investigates the use of measures to identify the causal relationship between ECoG signals during propagation of a seizure …

Acute Hyperbaric Oxygen Therapy Alters Vascular Reactivity Independent Of Atp, William Cole Waggener Iv

Masters Theses

Hyperbaric oxygen therapy (HBO), breathing 100 percent oxygen at greater than one atmosphere, has been prescribed for many different medical reasons. The mechanism for HBO, however, is not entirely understood. Adenosine triphosphate (ATP) is the main energy carrier molecule in the body and its production requires oxygen. By increasing the amount of oxygen carried by the blood, the amount of ATP could also increase. This possible mechanism for HBO was tested using the addition of exogenous ATP on approximately five millimeter wide rings of fresh porcine gut arteries. The vascular rings were attached to a force transducer which measured the …

The Relationship Between Maternal Child Feeding Practices And Child’S Bmi And Child’S Dietary Restraint In Mexican-American Families Of Grand Rapids, Mi., Larissa E. Fluegel

Masters Theses

Background. Research in Caucasian girls has shown a relationship between mother’s restrictive feeding practices and girls’ eating in absence of hunger and greater body mass index (BMI). Hispanic children disproportionately suffer from obesity, yet there are limited studies on this relationship.

Purpose. This study sought to examine the relationship between maternal feeding practices (MFP) and child BMI (BMI_ch); and to explore the effect of demographics and culture on the latter. The hypothesis that BMI_ch is positively correlated with dietary restriction and monitoring and negatively correlated with pressure to eat was tested.

Subjects. First or second-generation Mexican-American women …

Looking For Mr. Right Or Mr. Right-Now: A Content Analysis Of Gay Men’S Personals, Matt Reid

Masters Theses

Personal advertisements have long been valued by researchers for evaluating norms relating to love and romance in any given societal context. Using thematic, directed content analysis on ads placed on a popular online dating website, this exploratory study seeks to uncover the various ways by which gay and straight men craft an image of the ideal self.

Results largely diverge from previous studies, most of which were conducted prior to the advent of online dating and at a time in a society where homosexuality was more taboo. The current study found that gay men, more often than straight men, employ …

In Their Own Words: Healing From Traumatic Childbirth, Jennifer L. Brammer

Masters Theses

Trauma related to childbirth is seldom addressed despite the incidence of women who experience traumatic births. Birth trauma, like other traumatic events, can have a lasting impact on women and can effect their attachment to their infants. This study gives voice to women's birth trauma and describes what women find helpful in their healing processes from traumatic birth. This study is based on the narratives of 14 women who graciously shared their birth stories and healing journeys in semi-structured qualitative interviews. Their traumatic birth experiences occurred 3 ½ to 26 years ago.

A post-positivist approach and narrative theory informed this …

Facing The Idea That Facebook Faces Us Towards Narcissism, Adam Forsberg

Masters Theses

Since its creation in 2004, Facebook has experienced tremendous growth and success, allowing users to communicate and share their life with people all over the world. Facebook is used to share information with others and allows users to show their friends what is happening in their lives. Erving Goffman developed face management theory as a way to explain how and why people preserve and maintain their public self image. This study applies Goffmans theory of face management to develop an understanding of how Facebook is used and specifically whether Facebook use influences narcissistic tendencies in its users. The researcher surveyed …

Selling Life To Abortion-Seekers: A Content Analysis Of Passive And Active Persuasion In Crisis Pregnancy Center Marketing, Alexander Kocman

Masters Theses

For supporters of the pro-life cause, crisis pregnancy centers (or CPC's) have become the "darlings of the movement," according to the New York Times (Belluck, 2013), offering women with unplanned pregnancies free advice, information, classes, childcare, and needed supplies. For abortion advocates, such establishments are intended to seduce vulnerable abortion-seekers into a situation where they will be counseled out of an abortion and possibly even proselytized. Yet for as much controversy as exists in the news media, medical community, and legal realm about CPC's, there is an unsettling lack of understanding of how--and why--CPC's market themselves the way they do. …

Impersonal Trust In Versus Dependence On Fda, Amanda C. Meyer

Masters Theses

This study emerged following an examination of the work by Susan Shapiro (1987) delineating the construct of impersonal trust, and Shapiro's analysis of trust was applied to an understanding of the impersonal trust relationship which Americans have with Food and Drug Administration (FDA). Few fields outside of organizational studies have undertaken efforts to operationalize impersonal trust and to distinguish it from other related constructs, so this exploratory study assessed whether variables associated with interpersonal trust as outlined by Meyer and Ward (2009) were also associated with impersonal trust in FDA. This study further examined whether measures of impersonal trust could …

Understanding Work Socialization: A Qualitative Study Of A Youth Employment Program, Katelyn S. Sandor

Masters Theses

Through early work experiences, often in part-time jobs, young people come to learn about the working world. This learning process is often considered a source of anticipatory socialization, or an experience that comes before real work and serves to socialize individuals into particular organizations and vocations. In contrast, this study seeks to understand how individuals are socialized into broader meanings of work through early, part-time work experiences by studying a Youth Employment Program (YEP) aimed at providing hands-on job opportunities for at-risk youth. Drawing upon in-depth interviews, I analyze what young people learned about work and how such learning occurred. …

The Relationship Between Speaking Rate And Nasalance In Typical Adult Speakers, Rachel Whitney

Masters Theses

Nasometry is a non-invasive tool frequently used to measure speech resonance in clinical populations. The instrument uses an acoustic recording system to derive a measure termed nasalance, which is an estimate of the relative amount of acoustic energy emitted from the nasal cavity. Nasometry protocols do not provide detailed instructions for speaking rate control during data collection. Studies attempting to establish a relationship between speaking rate and nasalance have yielded mixed results; therefore, it is important to identify the influence of speaking rate on nasalance in a variety of speaking tasks. If rate is found to influence nasalance values, protocols …

Vaccinia Virus Flll Mediated Expedition Of Tanapoxvirus Replication In Cell Culture, Yih Wen Goh

Masters Theses

Tanapoxvirus (TPV) produces large but slow-forming plaques as opposed to vaccinia virus (VACV) that forms similar large plaques but more rapidly. A number of genes were identified in VACV, inclucding FllL, A33R, A34R and A36R that contribute to the regulation of virus release and dissemination, and are particularly responsible for the induction of actin tails. Among them, TPV lacks homologs of the FllL and A36R genes. F11Lmediated inhibition of RhoA-mDia signaling was shown to enhance the microtubules dynamics and modulates the cortical actin that assisted in the release of progeny virus from infected cells. To understand the possible effects of …

No Fracking Way! A Study On The Spatial Patterns Of And Changes In Perception And Distance From A Michigan Horizontal Hydraulic Fracturing Site, Shannon Mcewen

Masters Theses

The research investigates whether Michigan residents' perception of risk from an oil and natural gas (ONG) well site that employs the use of horizontal hydraulic fracturing (fracking) changes with distance. The research goal is to determine if residents that live farther from a fracking site perceive it to be more dangerous than those who live closer. Secondary research goals include determining if increasing distance from a fracking site cause residents to overestimate their proximity to a fracking site and if gender and education levels have an effect on residents' perception levels. Data were collected from residents in three counties in …

Arts Outreach In The Middle East, Matthias Clark

Masters Theses

After centuries of debate and discussion regarding the value and appropriateness of arts in the Middle East, specifically music, many indigenous people have recently pursued active roles in championing indigenous and international arts toward social reform, identity formation, and spiritual development. This shift in use and function of the arts has been reflected in some groundbreaking attempts of using arts in contextualized forms that have impacted spiritual communities. This study is designed to compare two specific case studies that exemplify these shifts: the "School of Worship and Music" and the "Creative Center". These organizations will be analyzed and compared in …

Evaluating The Success Of Wetland Mitigation In West Michigan: A Macroinvertibrate-Based Approach, James N. Neal

Masters Theses

Michigan’s wetlands, and their invaluable natural services, were declining at an alarming rate; therefore, the process of wetland mitigation was introduced in 1979 to offset this loss. From 2003-2006, a series of mitigated wetlands were installed to compensate for the wetlands removed during the construction of the M-6 highway south of Grand Rapids, MI. The objectives of my research were to determine whether these man-made wetlands function similarly to natural wetlands in terms of biological integrity, further develop methods for a macroinvertebrate-based index of biological integrity for inland wetlands, and provide pragmatic suggestions for wetland mitigation practices. Macroinvertebrate, plant, and …

Energy Tradeoffs Between Food Assimilation, Growth, Metabolism And Maintenance, Lihong Jiao

Masters Theses

"The effect of metabolic rate (MR) on organisms' health maintenance is a long-standing puzzle and empirical data on this issue is contradictory. A theoretical model was developed for understanding animal's energy budget under the food condition of Ad libitum (AL) and food restriction. This model offers a framework for understanding the role of MR and health maintenance mechanism from the perspective of energy tradeoff between food assimilation, growth, metabolism and maintenance. Hornworm (Manduca sexta larva) has been selected as an model to test the energetic tradeoff under different food supply and ambient temperatures. The changes in energy budget can …

Analysis And Modeling Of Resilience For Networked Systems, Kamlesh Ashok Joshi

Masters Theses

"A cyber physical system (CPS) has two main subsystems; a physical infrastructure that is responsible for managing and implementing physical tasks, e.g., generation and distribution of a physical commodity, and a cyber infrastructure that is used to support and enhance these physical operations through computing, communication, and control. Imperfect cyber control can lower the efficacy and even reliability of existing physical infrastructures. As such, justifiable reliance on CPSs requires rigorous investigation of the effect of incorporating cyber infrastructure on functional and non-functional aspects of system performance. One non-functional metric of note is resilience, defined as the ability of a system …

The Effectiveness Of Student Success Courses On Students Enrolled In A Remedial Reading Course, Emily Walters
