A Qualitative Study Of Factors Promoting Doctoral Attainment Of Second-Generation Mexican American Males From California, Jorge Chavarin

Dissertations

Research on second-generation Mexican American males who attain a doctoral degree is limited. Often, the data presented clusters Mexican Americans under the Latina/o or Hispanic ethnic group, focuses on factors that hindered educational attainment or details Latino male experiences in the context of their Latina female counterparts. Mexican-Americans are the largest subgroup of this ethnic group yet little is known about their post-secondary educational experiences. Rather than focusing on barriers, this study concentrated on the factors that influenced eight Mexican American males from California who attained their doctorates from a doctoral-granting university within California.

Arguably, the self-efficacious men of this …

The Learning Needs Of Community College Emerging Scholars, Janet K. Walsh

Dissertations

The community college mission has always centered on providing higher education opportunities for all people (American Association of Community Colleges [AACC], 2015a; Bailey, Jaggars, & Jenkins, 2015; Dassance, 2011; Dotzler, 2003; Greenburg, 2008; Schuh, Jones, Harper, & Associates, 2011). However, many students who enrolled at the community college level were not college ready and often required developmental coursework to help bridge the knowledge gap prior to taking college level courses. Unfortunately, those students were unlikely to obtain higher education credentials (Bailey et al., 2015; Carnegie Foundation, 2014). On the other hand, the researcher observed a relatively small number of students …

Terahertz Wireless Communication Through Atmospheric Atmospheric Turbulence And Rain, Jianjun Ma

Dissertations

This dissertation focusses on terahertz (THz) wireless communication technology in different weather conditions. The performance of the communication links is mainly studied under propagation through atmospheric turbulence and rain. However, as real outdoor weather conditions are temporally and spatially varying, it is difficult to obtain reproducible atmospheric conditions to verify results of independent measurements making it a challenge to measure and analyze the impact of outdoor atmospheric weather on communication links. Consequently, dedicated indoor weather chambers are designed to produce controllable weather conditions to emulate the real outdoor weather as closely as possible. To emulate turbulent air conditions, an enclosed …

Semantics And Result Disambiguation For Keyword Search On Tree Data, Cem Aksoy

Dissertations

Keyword search is a popular technique for searching tree-structured data (e.g., XML, JSON) on the web because it frees the user from learning a complex query language and the structure of the data sources. However, the convenience of keyword search comes with drawbacks. The imprecision of the keyword queries usually results in a very large number of results of which only very few are relevant to the query. Multiple previous approaches have tried to address this problem. Some of them exploit structural and semantic properties of the tree data in order to filter out irrelevant results while others use a …

Plasticity Of The Cortical Representation Of Finger Extensors Induced By Paired Associative Stimulation, Ian Anthony Gerard Lafond

Dissertations

This dissertation first explored associative plasticity of the human motor cortical representation with the use of noninvasive transcranial magnetic stimulation (TMS) paired with peripheral electrical stimulation. Paired Associative Stimulation (PAS) has grown in popularity because of its potential clinical applications. PAS techniques are used in combination with electromyography (EMG) measurements to study cortical excitability and features of hand movement. This work focuses on a cohesive approach to answer central questions about: the ideal mechanism to facilitate cortical plasticity via PAS, the interaction between the behavior performed and type of stimulation delivered to the targeted cortical network and the effects of …

Generalized Dft: Extensions In Communications, Yuewen Wang

Dissertations

Discrete Fourier Transform (DFT) is a restricted version of Generalized DFT (GDFT) which offers a very limited number of sets to be used in a multicarrier communication system. In contrast, as an extension on Discrete Fourier Transform (DFT) from the linear phase to non-linear phase, the proposed GDFT provides many possible carrier sets of various lengths with comparable or better performance than DFT. The availability of the rich library of orthogonal constant amplitude transforms with good performance allows people to design adaptive systems where user code allocations are made dynamically to exploit the current channel conditions in order to deliver …

Task-Based User Profiling For Query Refinement (Toque), Chao Xu

Dissertations

The information needs of search engine users vary in complexity. Some simple needs can be satisfied by using a single query, while complicated ones require a series of queries spanning a period of time. A search task, consisting of a sequence of search queries serving the same information need, can be treated as an atomic unit for modeling user’s search preferences and has been applied in improving the accuracy of search results. However, existing studies on user search tasks mainly focus on applying user’s interests in re-ranking search results. Only few studies have examined the effects of utilizing search tasks …

Predicting Intake Of Applications For First Registration In The Property Registration Authority, Orlaith Mernagh

Dissertations

The motivation for this dissertation is rooted in a real business need. The Property Registration Authority is the state organisation tasked with maintaining a register of land ownership on the island of Ireland. The PRA currently faces a series of challenges; a high level of staff retiring and the inherent loss of knowledge associated with this trend, a lack of recruitment in recent years and a large increase in lodgement of applications for first registration as a result of legislation. The organisation therefore requires a reliable system for predicting future intake. Prior to this project, there has also been a …

What Is Mortal Shall Be Swallowed Up By Life (2 Cor 5:4): A Critical And Constructive Engagement With John Hick's Theology Of Death In Death And Eternal Life (1976), Hongmei Zhao

Dissertations

The springboard for my investigation is John Hick’s theology of death or “par-eschatology” in Death and Eternal Life (1976), a postmortem soteriology rooted in Irenaeus’ teleological framework of person-making. I organize my project around the two constitutive aspects of human existence: time and space, or temporality and embodiment.

Regarding postmortem temporality, I present: 1) new scholarships in the New Testament, early Christianity, and Reformation studies, and 2) recent developments in ecumenical dialogues and the Justification-Sanctification Debate. Through this, I demonstrate a widely emerging emphasis–the centrality of sanctification in the Christian understanding of salvation. I argue that this crystalizing consensus lends …

Pickup Ion Production In The Global Heliosphere And Heliosheath, Yihong Wu

Dissertations

Pickup ions (PUIs) play a significant part in mediating the solar wind (SW) interaction with the interstellar medium. In this dissertation, I examine the details of spatial variation of the PUI velocity distribution function (VDF) in the SW by solving the PUI transport equation. I assume the PUI distribution is isotropic resulting from strong pitch-angle scattering by wave-particle interation. I take into account the effects of convection with the SW, adiabatic cooling, second-order Fermi process and production of PUIs. I analyze how PUIs transform across the heliospheric termination shock (TS) and obtain the PUI phase space distribution in the inner …

Mirage : O(N) Time Analytical Multi-Camera Pose Estimation Method With Application To Trajectory Tracking Problem, Semih Dinc

Dissertations

Camera pose estimation is a critical stage for the vision based robotic control systems, since precise motion can be achieved by successful localization. Today, many robotic systems, such as unmanned vehicles, robotic arms, and other automation systems rely on vision systems. Additionally, emerging technologies, such as depth sensors and virtual/augmented reality headsets need accurate and reliable pose estimation algorithms. To serve this purpose, in this dissertation, a novel pose estimation algorithm called Mirage is proposed. Mirage estimates the camera pose in 3D Euclidean space by utilizing a desired camera pose and actual 2D view of a reference object. Mirage minimizes …

Status Quo Vs. Change In The Face Of Death And Uncertainty, Justin S. Cheng

Dissertations

A diverse array of empirical research posits a general tendency for people to prefer the status quo over change, all else being equal. In two experiments, we explore the status quo preference phenomenon from a motivated cognition, uncertainty management perspective. Extending the precepts of several related empirical traditions (e.g. terror management theory, system justification theory and related topics), we explore the premise that uncertainty management processes activate social cognitive mechanisms directly favoring the status quo, similar to previously established process mechanisms such as terror management. Across two studies, we find support for the idea that both uncertainty and mortality salience …

Transformative Models In K-12 Education: The Impact Of A Blended Universal Design For Learning Intervention, Kai Monet Mathews

Dissertations

Accountability measures, by way of standardized curriculum and assessments, have played a large part in the attempt to ensure that students from all backgrounds receive equal access to quality education. However, the inherent disadvantage of a standardized system is the implied assumption that all students come in with the same knowledge, learn at the same pace, and learn the same way. In the wake of an increasingly diverse K-12 population, educational researchers, learning theorists, and practitioners agree that the concept of the average student is, in fact, a myth. Students come to school with different needs, norms, interests, cultural behavior, …

Exploring The Intersection Of Fat+Wom*N+Leadership: An Action Research Study, Jessica Jamese Williams

Dissertations

Cultural propaganda promotes an ever-changing feminine ideal which is parasitically reliant on women preoccupying themselves—ourselves—with our physical aesthetic. For women that identify as fat, most spaces openly neglect or are simply intolerant of her and even the stores meant for her are riddled with products meant to bind, reshape and essentially change her body. Fat women embody the paradox of being both conspicuous and unseen. Within systems, fat women are often silenced by shame, bias and discrimination; the unwanted and soiled identity hold us at the margins and serving as a barrier to effectively connect with others and practice leadership. …

Parental Involvement, Socio-Economic Status And Students' Perceptions Of The Classroom Learning Environmnet As Predictors Of 8th Grade Students Academic Achievement: A Structural Equation Model, Allyson Blandin

Dissertations

Problem

Academic achievement among the nation’s youth has been on the decline for decades. The statistics from the National Assessment of Educational Progress (NAEP) paints a bleak picture of the academic performance of more than half of the 4th and 8th grade students being below the required levels of proficiency in reading and mathematics. This is evidence that a problem of low academic achievement exists among certain student groups within the public education system. Therefore, it creates an academic achievement gap, which is reflected in the disparity in the standardized scores between students of color from low socio-economic status with …

Using Tops For Identification Of Gifted Hispanic Students, Barbara Martin

Dissertations

USING TOPS FOR IDENTIFICATION OF GIFTED HISPANIC STUDENTS

Researchers have noted an underrepresentation of Hispanic ELL students in gifted education. A literature review revealed several problems encountered when assessing and identifying gifted Hispanics and have also suggested a variety of solutions including use of non-standardized alternative assessments. In this project, the researcher explored the attitudes of educators regarding the addition of a non-standardized tool. The TOPS is a non-standardized tool used to systematically gather and document qualitative observational data within the context of instruction (Harradine, Coleman, & Winn, 2014). The researcher used both a survey questionnaire and a semi-structured interview …

How Can Parent-Child Interactions In A Museum Support Children’S Learning And Transfer Of Knowledge, Maria Marcus
