Abstract/Description
Community colleges provide open access and affordable options for higher education to a growing population of adult English Language Learners (ELLs) in the United States. Language minority groups, particularly native Spanish speakers, are currently the fastest growing demographic in the nation. Community college English as a Second Language (ESL) courses constitute a vital support for these students by providing adult ELL students with foundational college literacy skills.

Show moreCommunity colleges provide open access and affordable options for higher education to a growing population of adult English Language Learners (ELLs) in the United States. Language minority groups, particularly native Spanish speakers, are currently the fastest growing demographic in the nation. Community college English as a Second Language (ESL) courses constitute a vital support for these students by providing adult ELL students with foundational college literacy skills. With the growing demand for college graduates in today's workforce, language minority students, like their native English-speaking (NES) counterparts, need to leave college with vendible work credentials. Community colleges need practical and affordable ways to improve learning and degree completion rates of their English language learners. College ESL programs face two key challenges in realizing this goal: (1) providing quality language preparation for college-bound E LLs, and (2) developing efficient ways to deliver curricula to a student population that has limited financial resources and time. This was a single institution case study that investigated two ESL curriculum models at a large urban community college. The study compared the academic performance and persistence of ELL students who studied in a sheltered ESL curriculum to ELL students who studied in a concurrent enrollment ESL curriculum that combined college-level courses with advanced ESL study. The researcher analyzed student data from college archives: transcript data, admission data, and course performance results. Data from three student groups were salient to the study -- students in concurrent enrollment courses (partially-mainstreamed ESL students), students in traditional ESL courses (not mainstreamed), and native English speakers in freshmen-level general education courses. The study described the relationship between the two types of ESL curriculum and the academic performance and persistence of ELL students in each program. Findings showed that advanced ELL students were able to successfully complete select college courses as they finished their ESL program. Results indicated that early access to college courses motivated students to persist. This study can help ESL practitioners and administrators in higher education determine if a concurrent enrollment curriculum model is a viable alternative for intermediate and advanced level ELL students.

Show moreIn 1994 when Peter Shor released his namesake algorithm for factoring and solving the discrete logarithm problem he changed cryptography forever. Many of the state-of-the-art cryptosystems for internet and other computerized communications will become obsolete with the advent of quantum computers. Two distinct approaches have grown to avoid the downfall of secure communication: quantum cryptography which is based in physics and information theory, and post-quantum cryptography which uses mathematical foundations believed not to be weak against even quantum assisted adversaries. This thesis is the culmination of several studies involving cryptanalysis of schemes in both the quantum and post-quantum paradigms as well as mathematically founded constructions in the post-quantum regime. The first two chapters of this thesis on background information are intended for the reader to more fully grasp the later chapters. The third chapter shows an attack and ultimate futility of a variety of related quantum authentication schemes. The fourth chapter shows a parametric improvement over other state-of-the-art schemes in lattice based cryptography by utilizing a different cryptographic primitive. The fifth chapter proposes an attack on specific parameters of a specific lattice-based cryptographic primitive. Finally, chapter six presents a construction for a fully homomorphic encryption scheme adapted to allow for privacy enhanced machine learning.

Abstract/Description
Excelencia in Education (2016) reported that 21% of traditional age college male students were Latino males, second only to White males. The report further noted that Latino males are ranked the lowest in degree attainment – of whom only 20% have earned an associate’s degree or higher (Excelencia in Education, 2016). As an insufficient number of Latino males are graduating with post-secondary degrees, more research must be conducted to explore their educational journey from the community...
Show moreExcelencia in Education (2016) reported that 21% of traditional age college male students were Latino males, second only to White males. The report further noted that Latino males are ranked the lowest in degree attainment – of whom only 20% have earned an associate’s degree or higher (Excelencia in Education, 2016). As an insufficient number of Latino males are graduating with post-secondary degrees, more research must be conducted to explore their educational journey from the community college to the university and how to best support them through their transition. Therefore, the purpose of this qualitative narrative research study was to explore the stories of Latino male students as they transfer from a community college to a university. To capture the essence of Latino male students’ stories through the community college transfer experience to university, the research questions focused on what motivated and influenced their journey through the community college to a university. The research questions that guided this study were: What motivated and influenced Latino males’ decisions to enroll in a community college? What motivated and influenced Latino males’ decisions to transfer from a community college to a university? How do Latino male transfer students describe their transition from community college to a university? In this qualitative narrative research study, 10 participants participated in in-depth, semi-structured virtual interviews and completed two journal prompts. To assist in triangulation and validity, participants reviewed the data for accuracy, and thick rich descriptions were used to provide breadth and depth to their narratives. Once the data were collected, it was organized through the qualitative research data management software MAXQDA and analyzed using in vivo, descriptive, and pattern coding. The conceptual frameworks that informed this narrative study were the hero’s journey by Joseph Campbell (2008) and transition theory by Nancy K. Schlossberg (2011).
