Does Global Citizenship Education Predict Identification With All Humanity?, Alpha Amber Scott Belt

Dissertations

Scholars and leaders agree institutions of higher education must prepare students to live, work and thrive in a global community. Nevertheless, there remains much discourse and debate surrounding what it actually means to be a global citizen, and what are the appropriate learning opportunities that will best serve to achieve this goal. This quantitative study examined whether or not participation in global citizenship education opportunities predicts how a student identifies him- or herself in relation to all humanity as measured using the Identification with All Humanity (IWAH) scale (McFarland et al., 2012). Four research questions were examined 1) does participation …

Hand Control Of Bipedal Balance In Quiet Standing: Implementations For Lower Extremity Exoskeleton, Ala’A Al-Rashdan

Dissertations

Maintaining stable posture is important for humans, even though it is challenging because of our bipedal structure. One of the main balance related disorders is paraplegia due to spinal cord injury. People with a complete spinal cord injury have motor and sensory impairment that greatly reduces the ability to move their lower extremities. In recent years, lower extremity exoskeletons that apply torques generated by motors to the joints of the person have helped to them stand and walk.

This research is a part of an extended project to build a new exoskeleton for use by individuals with paraplegia due to …

A Study On Sanguinarine As An Antileukemic Agent- Involvement Of Reactive Oxygen Species-Ceramide-Akt Apoptotic Signaling Pathway, Anees Rahman Cheratta

Dissertations

Dysregulation of apoptosis is a prime hallmark of leukemia. Therefore, drugs which restore the sensitivity of leukemic cells to apoptotic stimuli are promising candidates in the treatment of leukemia. The main objective of this dissertation was to examine the antileukemic effect of sanguinarine, in vitro, and to further examine the signaling mechanisms that may be involved. This study demonstrates that in human leukemic cells, sanguinarine activates a caspase-dependent apoptotic cell death pathway that is characterized by reactive oxygen species-dependent ceramide generation, and subsequent inhibition of Akt signaling pathway. In addition, sanguinarine also induces reactive oxygen species-dependent glutathione depletion and …

The Perceived Community Engagement Survey: Structure, Reliability, And Validity Of A Community-Based Organization Measure Of Engagement With The Broader Community, Rafael Rivera

Dissertations

For more than 40 years government funding for community non-profit organizations has grown more than in previous decades. This dramatic increase has led to a proliferation of organizations that claim the status of community-based organizations. Community-based Organizations (CBOs) have become the service delivery providers of communities, particularly underrepresented communities. There has been very little research within the community psychology and other literature exploring if CBOs represent the interest of communities.

As funding entities have lately increased their interest in community representation, there has not been a corresponding research base to identify levels of community engagement. This study attempted to address …

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 …

Determining who is influential in a network, how information spreads and what translates to buy or sell decision is potentially very lucrative. In this research paper a dataset from …

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 …

Trauma In The Classroom: Teachers' Perspectives On Supporting Students Experiencing Child Traumatic Stress, Kassandra Reker

Dissertations

Each day, students across the nation carry personal trauma histories into the classroom. According to the Substance Abuse and Mental Health Services Administration (SAMHSA, 2014), trauma “results from an event, series of events, or set of circumstances that is experienced by an individual as physically or emotionally harmful or threatening and that has lasting adverse effects on the individual’s functioning and physical, social, emotional, or spiritual well-being.” With nearly half of all children experiencing at least one adverse childhood event (Child and Adolescent Health Measurement Initiative, 2013), teachers’ approach to addressing trauma in the classroom is critical. Yet our understanding …

The Psychological Impact Of Smartphones: The Effect Of Access To One's Smartphone On Psychological Power, Risk Taking, Cheating, And Moral Orientation., Amanda Christine Egan

Dissertations

Egan and Larson (2015) found that access to one’s smartphone resulted in an increase in one’s sense of psychological power. Psychological power is associated with a variety of behavioral outcomes, many of them moral in nature (Keltner, Gruenfeld, & Anderson, 2003). This dissertation attempted to conceptually replicate the findings obtained by Egan and Larson (2015) and to extend them by testing whether smartphone-induced power had moral implications. Specifically, Study 1 tested whether access to one’s smartphone increased psychological power, and in turn promoted risk taking and a shift in moral orientation. Study 2 tested whether access to one’s smartphone increased …

Electroosmotic Microfluidic Oligonucleotide Synthesis Reactor, William R. Gaillard

Dissertations

The principle objective of this dissertation is the development of a microfluidic oligonucleotide (oligo) synthesis reactor that sequences oligos with equal quality to commercial synthesizers and with equal waste reduction to previously published microfluidic synthesizers. The microfluidic approach to oligo synthesis increases throughput due to parallelization, provides simplification by integration of multiple functions into one platform, and decreases cost due to miniaturization and waste reduction. Microfluidic oligo synthesizers demonstrate these advantages over industrial synthesizers but have error rates that are too high for commercialization. The microfluidic synthesizer design investigated in this dissertation incorporates several innovations to reduce the error rates …

Transverse Stratified Structure For Tunable Beaming And Filtering At Terahertz Frequencies, Daniele Lo Forti

Dissertations

The terahertz field is rapidly expanding due to technological progress over the last few years.

In this work a number of transverse stratified configurations of metal and dielectric layers are studied for modulating Terahertz radiation in amplitude and phase. The first configuration analyzed is a set of metal plates placed on top of each other and separated by a thin layer of Liquid Crystal (LC). The period of the grating is such that the only propagating order is …

Robust Support Media For High Throughput Chromatographic Separations, Javier Sanchez Santiago

Dissertations

Affinity chromatography is used to separate biomolecules based on highly specific interactions, such as receptor and ligand, enzyme and substrate or antigen and antibody. Traditional chromatographic separation systems have the disadvantages of low flowrates, high pressure drop across the column, low capacity and poor reusability. Ceramic monoliths have been previously used as active support for affinity chromatographic columns due to their compact geometry and outstanding mechanical properties. In addition, mathematical models have been developed in order to determine the adsorption and elution times depending on the monolith geometry. The reversible interaction between L-asparagine and L-asparaginase has been exploited, using a …

A Mixed Methods Exploration Of Minority Resource Eligibility For Half White Multiracial College Students, Nicholas Reyes Franco

Dissertations

Over the last several decades, multiracial populations have received increased attention in academic literature, particularly regarding identity development and psychological health and wellness. Less attention has been given to individuals with one minority and one white parent (i.e., half white individuals) in the context of affirmative action and higher education. Existing quantitative studies on this topic suggest, on the one hand, that half white individuals are likely to be considered members of racial minorities, yet, on the other hand, less of a minority—and less deserving of affirmative action benefits—than monoracial individuals or multiracial individuals with multiple minority identities. College students’ …

Clients As Voting Board Members: A Mixed Methods Examination Of San Diego County Nonprofit Human Services Organizations, Elaine Marie Lewis

Dissertations

The literature suggests that thoughtful board composition generates more strategic and thoughtful policymaking. This study examined one aspect of board composition that is frequently cited as a source of more strategic and thoughtful policymaking: clients as voting members.

This study used descriptive and inferential statistics to examine the prevalence of, and the factors associated with clients participating as board members of human services nonprofit organizations in San Diego County. Through a review of the most recent 12 months of board meeting notes, this study also explored the level of participation of two clients on the board of directors of one …

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, …

Understanding Women Leaders In A Male-Dominated Profession: A Study Of The United States Marine Corps' Women Generals, Marianne S. Waldrop

Dissertations

Contemporary organizations are increasingly realizing that future success requires a significant shift in leadership due to globalization, flattened organizational command and control structures, rapid technology growth, and the shift from manufacturing to service industries. Specifically, current leaders and scholars have begun to recognize the importance of employee diversity within organizations, and in particular the critical need to tap into the underutilized half of the population—women. Yet, the efforts to recruit, develop or retain women has been minimal, leading to metaphors such as glass ceiling and labyrinth, which characterize the institutional, social and personal barriers women encounter when seeking high-level leadership …

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. …

An Exploration Of The Use Of Photovoice-Inspired Techniques To Facilitate Narrative Leadership In A Small Group Of Middle-Aged Women, Michelle M. Zive

Dissertations

Leadership often is defined as a persuasive relationship. Over the last two decades, narrative leadership has been viewed in the Leadership Studies literature as a source of persuasion. Narrative leaders use stories to impact others in both large-scale political and social movements, as well as in large-scale organizations. Even as this has been happening, the field also has begun to re-conceptualize leadership as a group rather than an individual process, a view of leadership sometimes characterized as shared leadership. There is limited understanding of whether narrative leadership operates in shared leadership situations and a dearth of literature about specific techniques …

Clones In The Mba Classroom: Understanding The Relationship Between Culture And Mba Students’ Attitudes Toward Socially Responsible Business Leadership: A Mixed Methods Cross-National Study, Juan F. Roche

Dissertations

Recurrent corporate scandals have underscored the need for business leaders, the majority of whom were trained in business schools, to address tradeoffs between the interests of investors and those who serve the common good as an expression of socially responsible business leadership (SRBL). This study offers an integrated corporate social responsibility model (ICSRM), which displays the factors that scholarly research suggests promote and hinder corporate social responsibility (CSR) practice. However, because the CSR concept originated in the United States and the American business school model is replicated across the globe, most theories that support this conceptual framework were developed through …
