Towards Automated Domain-Oriented Lexicon Construction And Dimension Reduction For Arabic Sentiment Analysis, Hasan A. Alshahrani

Dissertations

Sentiment analysis is a type of text mining that uses Natural Language Processing (NLP) tools to identify and label opinionated text. There are two main approaches of sentiment analysis: lexicon-based, and statistical approach. In our research, we use the lexicon-based approach because the lexicon contains sentiment words and phrases which are the main linguistic units to express sentiments. More specifically, we work with domain-oriented lexicons as they are more efficient than general ones because the polarity is heavily driven by domains.

Arabic language has a degree of uniqueness that makes it hard to be processed with the available cross-language tools …

Color-Blind Racial Ideology, Social Justice Attitudes, And Cultural Competency In U.S. Medical Students And Resident Physicians, Jennifer G. Hahm

Dissertations

Health disparities disproportionately affect the lives of racial and ethnic minorities in the United States (Agency for Healthcare Research and Quality, 2015; U.S. Department of Health and Human Services NHQR, 2013). Social conditions, social determinants, and structural inequities have been acknowledged as influential forces on minority health (Link & Phelan, 1995; World Health Organization, 2011). Focusing on eliminating environmental and social conditions affecting the health status of racial and ethnic minorities should be a prerogative for healthcare professionals in reducing health disparities. The purpose of this study is to examine the relationship between color-blind racial ideology and social justice attitudes …

The Effect Of Item Stem And Response Option Length On The Item Analysis Outcomes Of A Career And Technical Education Multiple Choice Assessment, Tina M. Koepf

Dissertations

Critical decisions in Career and Technical Education (CTE) can be based on assessment outcomes, requiring an essential focus on continuous improvement initiatives to provide increased multiple choice (MC) assessment validity. Previous research has determined that the presence of flawed test items negatively impacts student success; therefore, an MC taxonomy has been established and used in the assessment industry. While rigorous and successful Career and Technical Education (CTE) programs that enroll high-level academic students exist, many CTE programs enroll students with a wide spectrum of academic ability. Because many CTE students often have inferior reading skills, it is necessary to take …

Teacher Perceptions Of Ability In Implementing A Culturally Responsive Educational Practice For Culturally Linguistically Diverse Students With Dis/Abilities, Melanie Ziebatree

Dissertations

All children in the United States have the right to an equitable education, regardless of gender, religion, class, race, culture, language, or dis/ability. The literature demonstrates that financial, educational, and legal outcomes are disproportionately negative for those students falling outside of white able-bodied norms and that educational institutions often perpetuate exclusive policies and practices that disproportionately impact culturally linguistically diverse students with dis/abilities. A critical examination of the sociopolitical and contextual factors that fortify the barriers faced by marginalized groups highlights the need for a culturally responsive approach to educating students with multidimensional identities.

To serve the needs resulting from …

An Evaluation Of Early Childhood Education Programs: The Parents’ Perspective Of Quality Care, Buu Chau Thai

Dissertations

Early childhood education (ECE) programs play a critical role in the social, emotional, and cognitive development of children and help to prepare them for kindergarten. Recognizing the benefits of ECE programs, state and federal governments have made notable efforts to make these programs more accessible. However, with various federal, state, and local governments involved in administering and funding ECE programs, a complex, fragmented, and oftentimes confusing system ensued, making the ECE landscape very difficult for parents to navigate. Parents are often the primary decision-makers when selecting educational programs for their children. Studies often focus on practitioners’ or researchers’ perspectives on …

Optimizing Strategic Sourcing In The Healthcare Supply Chain With Consideration Of Physician Preference And Vendor Scorecards, Parimal Kulkarni

Dissertations

This research focuses on the design of a procurement model for expensive medical supplies in a healthcare supply chain. A deterministic optimization model generates recommendations for optimal purchases of products in a given planning period. The model combines common concepts of supply chain procurement such as leveraging tiered pricing, ensuring supply base diversity with phenomena unique to healthcare supply chain such as consideration of physician preference for products. The deterministic optimization model minimizes total spend over a chosen planning period with consideration of four key decision parameters:

• Physician preference requirements (which are imposed as rules on product substitutability),
• Upper limits …

Narrowing The Opportunity Gap: Developing Culturally Sustaining Pedagogy For Culturally And Linguistically Diverse Students, Niles Engerman

Dissertations

As per Breeze and Laborda (2016), a culturally responsive curriculum addresses the integration of students into a new culture, as bilingual education traditionally receives minimal interest from the authorities. Akkari and Loomis (1998) explain that bilingual education is socially and historically situated, while van Lier (2004) posits that diverse linguistic groups will have an ominous future if the educational system ignores their linguistic needs. This demands a paradigmatic shift to meet the needs of culturally and linguistically diverse students (CLDs). Advocating for culturally responsive curriculum, this defense will examine the history of bilingual education in the United States, linguistic ecology, …

Ten Elementary School Teachers’ Voices: How They Build Effective Literacy Learning In The Lives Of Their 2nd Grade Children, Merfat Ayesh Alsubaie

Dissertations

It is important to support teachers to adapt and apply effective literacy instruction strategies. Teachers may receive support from many sources, such as pre-service developers, principals, supervisors, literacy coaches, parents, colleagues and peer teachers. Perhaps most importantly, the teaching of literacy requires the support of the principal, literacy coach, and others who can collaborate with the classroom teacher to implement effective literacy instruction and strategies (Vallejo & Wren, 2009; Cole, 2008). All of these supports play a role in effectively achieving high literacy levels among students (Cole, 2008). Thus, teachers should work to maximize the benefit they receive from these …

Iranian Leadership Ideals: A Culturally-Based Leadership Approach, Azadeh Davari

Dissertations

In light of many current financial and ethical crises, scholars have called for looking beyond our existing Western-based approaches for innovative leadership practices. Recent research about the success and unique management practices of Indian corporations (Cappelli et al., 2010) shows a unique style based on both people and profit and one that blends capitalist profit-based structures with caring for people and community. That research has been the basis for suggestions for the existence of a distinct Indo-European leadership (IEL) style (Nahavandi, 2012a; Nahavandi & Krishnan, 2017) with philosophical roots in Iran and India and provides impetus for looking beyond Western …

Career Decision-Making Of Higher Education Professionals Of Philippine Descent: The Untold Stories Of An Asian Pacific Islander Community, Grace Abenoja Bagunu

Dissertations

Using a critical race theory (CRT) framework and a narrative and phenomenological methodology, this study explored the career decision-making of professionals of Philippine descent along the higher education career pipeline in the United States. The stories of these professionals create a counter-narrative to the stereotypes of Asian and Pacific Islanders (APIs) in higher education. The career pipeline in higher education has remained relatively homogeneous, especially at executive levels of administration. Statistics show that APIs make up less than 1% of all college presidents, of that 1%, less than a handful identify as Filipinx.

This statistic alone does not completely tell …

Exploring Churn And Alignment Between Retention And Occupational Culture As Perceived By Professional Truck Drivers, Catherine M. Cole

Dissertations

Despite advances in logistics software and increased driver pay, the trucking industry continues a historic wave of human capital risks in the form of driver turnover and driver shortages. Previous efforts to understand the phenomenon of driver turnover rely heavily on supply chain, transportation, and logistics based disciplines. The current study provides a human capital ontology towards understanding professional truck driver perceptions. Within the interpretive framework of pragmatism, the study applied a simultaneous ethnographic and phenomenological research design to explore the phenomenon of churn and professional truck driver perceptions of environmental alignment between trucking industry retention strategies and the occupational …

Rendering Reliance: Consuming Coloniality In The Global North, Victoria L. Brown

Dissertations

In this dissertation, I offer a theoretical lens for understanding how the Global South is imagined by the Global North. The Global South has become a popular cause that for-profit companies use in order to engage in what Samantha King terms cause-marketing. While individuals in the South are certainly helped by these campaigns, they are harmed through Northern consumers being empowered by private companies encouraging them to adopt a colonizing gaze that subjugates those in the South with adhering to stereotypes. I develop three rhetorical devices that fulfill stereotypes long-held about those who are “other.”

First, I offer the endangered …

Culturally Relevant Pedagogy: Teacher Experiences And Impact On Student Learning, Jessica Denton

Dissertations

Growing public concern about the educational experiences of English language learners (ELL) has placed pressure on teachers and schools to provide equitable learning opportunities for this group of students. Currently, federal and state mandates promise to hold all students to the same high expectations, but ELLs consistently underperform academically. Such research suggests that culturally relevant pedagogy (CRP), specifically the inclusion of culture in the classroom, as well as the integration of students’ lived experiences can influence students’ learning opportunities.

This study was guided by existing theories of culturally relevant pedagogy, “funds of knowledge,” social maturity and cognitive development theories as …
