Electronic Theses and Dissertations

The University of New Mexico is proud to showcase the theses and dissertations of our graduate students. They have been collected here for public access and scholarly review, and all have received approval from the Dean of Graduate Studies at UNM.

Graduate Studies, the central graduate academic administrative unit at the University of New Mexico, is committed to helping our students succeed. Our staff is eager to assist students, staff, and faculty with all their graduate school needs.

Now that you have written and successfully defended your thesis or your dissertation, it is time for you to format your manuscript and submit it this digital repository here at UNM (Ph.D. students must also submit their manuscript to ProQuest). For information on the process, including formatting procedures, manuscript submissions, and delaying public access (embargo), please visit Graduate Studies website and explore our degree completion resources .

Cultural Sensitivity Statement

The UNM College of University Libraries and Learning Sciences’ department of Digital Initiatives and Scholarly Communications (DISC) provides digital access to campus research including the University's thesis and dissertations as evidence of degree fulfillment. The University was founded in 1889 and some published items reflect the perspectives and biases of the time in which they were created. Following best professional practices, UNM preserves data in its original form to retain authenticity and facilitate research, therefore, digital surrogates may include racial, derogatory, and demeaning language that we acknowledge is problematic. Insensitive or offensive language is not condoned by UNM. Photos, terms, depictions, and annotations reflect the attitude of the author or the period in which the item was created. These may be considered inappropriate today. 

We also strive to be respectful of the beliefs and practices of the many cultures that have been the subjects of research by members of the University. Additionally, in 2021 the College endorsed the Protocols for Native American Archival Materials which are guidelines for libraries and archives to engage in respectful stewardship of Native American collections. Therefore, we are continually working to learn about and follow cultural protocols for sensitive materials. This may include providing mediated access or restricting digital access to all or parts of specific theses and dissertations. These actions will be noted in an item record’s comments field. For items originally published in print form, a complete physical copy is retained by the library and may be accessed on site. 

Please contact DISC if you find items that may need to be reviewed.

The SAGE Handbook of Digital Dissertations and Theses

• Richard Andrews - University of East Anglia, UK
• Erik Borg - Coventry University, UK
• Stephen Boyd Davis - Royal College of Art, UK
• Myrrh Domingo - New York University, USA
• Jude England - British Library, UK
• Description

Topics covered include:

- how to make research more accessible

- the use of search engines and other sources to determine the scope of work

- research training for students

- what will theses, dissertations and research reports look like in ten years' time?

- the storing and archiving of such research

- ethics and methodologies in the field

- intercultural issues

The editors focus on advances in arts and practice-based doctorates, and their application in other fields and disciplines. The contributions chart new territory for universities, research project directors, supervisors and research students regarding the nature and format of Masters and doctoral work, as well as research projects.

This handbook is an essential reference for researchers, supervisors and administrators on how to conduct and evaluate research projects in a digital and multimodal age.

Richard Andrews is Professor in English, Faculty of Children and Learning, Institute of Education.

Erik Borg is a Senior Lecturer at Coventry University's Centre for Academic Writing.

Stephen Boyd Davis is Research Leader in the School of Design, Royal College of Art.

Myrrh Domingo is Visiting Assistant Professor in English Education and Literacy Education at New York University.

Jude England is Head of Social Sciences at the British Library.

'This handbook marks a major turning point in the production of dissertation and theses. Scholarly communication has been changing rapidly, embracing the latest in web searching, social media, and online and open access journals. Yet, attention to the dissertation - the hallmark of an academic education - has been sorely missing. This handbook identifies and explores the multiple ways in which electronic means are becoming an integral part of the production of dissertations today, as well as looking at the scope in the future scope for bringing electronic and new media forms into the final form of the dissertation. The handbook first situates the dissertation in its historical and institutional perpectives, and then addresses the transformation from print to digital in dissertations from supervision to production to archiving and accessibility. Finally, the handbook wraps up with a section on research methodologies and methods that rounds out the book with advice for prospective students on how to be the creator of a digital dissertation from inception to final delivery. This will be essential reading for all involved in contemporary university education' - Caroline Haythornthwaite, Director and Professor at the School of Library, Archival and Information Studies at the University of British Columbia

This is a useful source of ideas for students using digital media for their research, and those supervising this kind of research.

antiSMASH, Confidence, Identification Scoring, LC-MS QToF

Marine sediment-associated bacteria house many new and exciting novel secondary metabolites. These metabolites can be tested for bioactivity against various types of cancer and fungal, bacterial, and viral infections. In this thesis, we investigated the combination of biosynthetic gene cluster information with mass spectra to perform a chemical profiling of sediment- associated bacteria. Furthermore, we utilized a scoring technique to provide an identification and confidence score to each annotated compound. The sediment was collected from east Arthur Harbor, Palmer Station, Antarctica, at depths of 20 ft and 60 ft. After plating on agar, 52 unique bacterial strains were isolated, with the major phyla being Actinobacteria, Firmicutes, and Proteobacteria. Using NCBI BLAST we investigated the full genomes of neighboring taxa and look for biosynthetic gene clusters, which produce secondary metabolites of interest. These biosynthetic gene clusters, coming from the DNA sequences, through a metabolic pathway produce complex secondary metabolites of pharmaceutical value. These molecules can then be analyzed through mass spectral data, collected from the LC-MS QToF. This coupling allows us to use mass spectrometry with genomic information to annotate putative secondary metabolites provided by the biosynthetic gene clusters. After collecting the mass spectra for a subset of five isolates, each metabolite was annotated by its BGC and look at the fragmentation pattern in the data. To assist us with this, we utilized a scoring technique that awarded points to each compound based on the precursor ion and MS2 fragment ions. After totaling the points for each metabolite, the confidence scores ranged from fair, good, and strong. Applying this technique asserted a level of confidence behind each annotation of the parent ion and mass fragment ions. The three bacteria analyzed here were Streptomyces libani, Bacillus inaquosorum, and Sporosarcina globispora. Each strain was grown in tryptic soy broth and marine tryptic soy broth (at 3.5% salinity), centrifuged to separate the supernatant and cells, then prepared for mass spectrometry analysis. The metabolites that were annotated and given a confidence score between good and strong were streptomycin, antipain, caniferolide A, caniferolide B, caniferolide D, muraymycin C1, aurantinin B, and petrobactin. The analysis, including the mass error and mass resolution, for each molecule and their fragmentation patterns is provided.

Dissertation Defense: Illuminating the Path: The Impact of Digital Innovation on Diversity in Special Education Teacher Preparation Recruitment

Admin options.

This dissertation explores the impact of digital innovation on diversifying recruitment in special education teacher preparation programs. Amidst a critical shortage of special education teachers in the United States, the current research addresses the dual challenges of recruiting diverse educators and mitigating systemic disparities affecting students with disabilities. Utilizing Cultural Historical Activity Theory, the study critically evaluates Project RISE, an online recruitment platform designed to enhance the accessibility and inclusivity of special education teacher preparation programs.

The dissertation comprises three articles. The first article is a systematic literature review synthesizing findings on the role of technology in recruiting diverse educators, highlighting the potential of digital platforms to engage historically excluded groups. The second article presents an empirical study assessing the usability and efficiency of Project RISE. The third article offers practical recommendations based on these findings, advocating for integrating digital tools to streamline recruitment and support prospective educators from varied backgrounds.

Key findings indicate while traditional recruitment methods are limited in reach and effectiveness, digital platforms like Project RISE can bridge the gap by offering transparent, user-friendly access to program information. The study underscores the importance of culturally responsive recruitment strategies and the need for continuous user feedback to refine these digital tools.
