Dual-Detachment: The Plight Of Young Black Males Alienated From Work And School, Tšooane Molapo

Theses and Dissertations

In looking at the plight of young Black males who drop out of school or leave school without adequate skills to compete in the local and global labor markets, scholarship has overemphasized the likelihood of this population’s entrance into the juvenile justice system. Hence, many studies of these males have concentrated on their schooling experiences in the school-to-prison pipeline. While of crucial importance, prison is not the only danger for these young men. In time, some young Black males do end up in the juvenile justice system, but some remain stuck between school and employment. I term this “dual-detachment”—youth neither …

Failure Analysis Of Rotating Equipment Using Vibration Studies And Signal Processing Techniques, Ashkan Nejadpak

Theses and Dissertations

This thesis focuses on failure analysis of rotating machines based on vibration analysis and signal processing techniques. The main objectives are: identifying machine’s condition, determining the faults specific response, creating methods to correct the faults, and investigating available statistical analysis methods for automatic fault detection and classification. In vibration analysis, the accelerometer data is analyzed in time and frequency domain which will determine the machine’s condition by identifying the characteristic frequencies of the faults. These fault frequencies are specific for each type of machine’s faults. Therefore, they are referred to as faults’ signatures. The most common faults of the rotating …

Lightcurve Study Of V-Type Asteroids, Matt Nowinski

Theses and Dissertations

A massive impact event on (4) Vesta is believed to have created the Vesta family of asteroids (Asphaug, 1997). The rotational characteristics of the Vesta family provide important clues about this event, including its timing, the make-up of the resulting debris, the subsequent migration of members of the family into Earth-crossing orbits, and the deposition of the Howardite-Eucrite-Diogenite meteorites on the Earth’s surface. This study conducted lightcurve measurements of ten Vp-type asteroids, drawn from an asteroid taxonomy defined by Carvano et al. (2010) and based on the Sloan Digital Sky Survey (SDSS) Moving Object Catalogue (MOC4). These measurements identified a …

Stigma And Restoration Of Civil Rights To Felons, Kimberly Paige Pithey

Theses and Dissertations

Millions of people in the United States are banned from basic civil rights including participation in voting, jury duty, applying for government assistance, and owning a firearm because they have had a felony conviction. There is limited research on attitudes regarding the restoration of civil rights to felons. This thesis uses Goffman’s theory of stigma to examine whether public support for the restoration of rights to felons is associated with knowledge of felony convictions and whether an individual knows someone with a felony conviction. This study used an online survey of college undergraduates (N = 362) to explore two hypotheses …

Developmental Factors And Maladjustment Indicators Of Specific Sexual Interests, Victoria Charlotte Mary-Rose Pocknell

Theses and Dissertations

Human sexual expression appears to be freer to vary past the need to procreate. This study explores the variability in the cues that elicit sexual arousal in the general population. It aims to better understand the developmental factors and negative outcomes of having a specific sexual interest. A sample (N = 1069) was gathered using Amazon’s Mechanical Turk in which participants indicated sexual interests based on themes: Age, Physical Appearance, Clothing, Power, Risk, and Extrapersonal. The results suggest significant effects of sex, age, and hypersexuality on sexual interests. Therefore, analyses were run separately for men and women and age and …

Optimal Control Of Induction Machines To Minimize Transient Energy Losses, Siby Jose Plathottam

Theses and Dissertations

Induction machines are electromechanical energy conversion devices comprised of a stator and a rotor. Torque is generated due to the interaction between the rotating magnetic field from the stator, and the current induced in the rotor conductors. Their speed and torque output can be precisely controlled by manipulating the magnitude, frequency, and phase of the three input sinusoidal voltage waveforms. Their ruggedness, low cost, and high efficiency have made them ubiquitous component of nearly every industrial application. Thus, even a small improvement in their energy efficient tend to give a large amount of electrical energy savings over the lifetime of …

Immune Regulatory Mechanism And Myeloid Cells Functions In Brain Parasite Infection, Fredice Quenum Zangbede

Theses and Dissertations

Neurocysticercosis (NCC) is the most common parasitic infection of the central nervous system (CNS) caused by the helminth parasite Taenia solium (T. solium) and affects 50-100 million people worldwide. Its clinical symptoms include headache, seizures, hydrocephalus, epilepsy and stroke. These clinical symptoms can have life-long detrimental effects. As many as half of the total adult-onset seizures and 10% of the stroke cases in the endemic areas are attributed to NCC, whereas 20% to 30% of symptomatic patients display hydrocephalus. Treatment of NCC remains a major challenge as the severity of the symptoms is thought to be elicited by the degenerating …

Effect Of Bio-Binders On Binder And Mix Properties With High Rap Content, Rajib Chandra Saha

Theses and Dissertations

The use of Recycled Asphalt Pavement (RAP) has significantly increased in construction and rehabilitation of flexible pavements to ensure proper utilization of limited natural resources. Recycling also provides a greater environmental benefits and energy conservations. It saves the lands from being the dumping site, conserves energy, and reduces the emission of greenhouse gases. But high RAP in the HMA mix increases the stiffness and may result in cracking. Bio-binders could reduce the stiffness of binder and mixes with high RAP content. Two oils, namely Waste Cooking Oil (WCO), and Soy Oil are potential sources of bio-binder that are abundant and …

Quantification Of Lignin Hydroxyl Containing Functional Groups Via 31p{1h} Nmr Spectroscopy And Synthesis Of Lignin Degradation Standards, Joshua E. Schumaker

Theses and Dissertations

The focus of this thesis is on the structural characterization of lignin, a complex phenol-based heteropolymer. In the first part of the study, functionalization of lignin and its known degradation products by 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane (TMDP) and analysis by 31P NMR spectroscopy was investigated. Chemical shifts of derivatized alcohols, phenols, and carboxylic acids were determined that allowed for qualitative characterization of lignin. This approach was further applied for the quantitative analysis of OH-containing groups present in lignin employing the internal standard. Lignin samples, fractionated by gel permeation chromatography (GPC) based on molecular weights, were derivatized by TMDP and characterized by 31P NMR …

The integration of unmanned aircraft systems (UAS) into the national airspace system (NAS) poses considerable challenges. Maintaining human safety is perhaps chief among these challenges as UAS remote pilots will need to interact with other UAS, piloted aircraft, and other conditions associated with flight. A research team of 6 leading UAS research universities was formed to respond to a set of surveillance criticality research questions. Five analysis tools were selected following a literature review to evaluate airborne surveillance technology performance. The analysis tools included: Fault Trees, Monte Carlo Simulations, Hazard Analysis, Design of Experiments (DOE), and Human-in-the-Loop Simulations. The Surveillance …

Black Power In A "Lily-White" School: The Black Campus Movement At Concordia College In Moorhead, Minnesota, Daniel D. Cooley

Theses and Dissertations

Between the mid-1950s and through the 1970s, higher educational institutions throughout the United States underwent reforms in the name of what they termed “integration.” For the colleges and universities in the upper Midwest, these reforms included minority student recruitment and the creation of programs oriented towards diversity. Over time, a number of minority students began to act and react to the actions and attitudes of the various administrations, the campuses, and the community, resulting in a demonstration directly connected to the national phenomenon of “The Black Campus Movement,” (BCM) itself a submovement of the larger United States’ Black Power Movement …

Complexity Of Academic Socialization Of Historically Underrepresented Doctoral Students: De-Privileging Distinctions Between Macro-And-Micro-Theoretical Approaches, Zarrina Talan Azizova

Teaching, Leadership & Professional Practice Faculty Publications

This article represents a conceptual work that critiques and challenges traditional linear theoretical assumptions of academic socialization and integration that are often applied to research of diverse populations in academia in general and doctoral education specifically. The article further proposes a new conceptual framework of academic socialization as a meaning-making act of historically underrepresented doctoral students. The ultimate goal of the proposed framework is to reconcile the restrictive use of sociological macro- and micro- orientations to foreground possibilities of a conceptual and empirical focus on an individual meaning making act (as a form of individual agency) of historically underrepresented doctoral …
