Institutional Repository

The UDSpace Institutional Repository collects and disseminates research material from the University of Delaware.

  • Faculty, staff, and graduate students can deposit their research material directly into UDSpace. Faculty may use UDSpace to fulfill the University of Delaware Faculty Senate Open Access Resolution, and in many cases may use it to fulfill open access requirements from grant funding agencies.
  • Departments can use UDSpace to publish or distribute their working papers, technical reports, or other research material.
  • UDSpace also includes all doctoral dissertations from winter 2014 forward, and all master's theses from fall 2009 forward.

Review of Education in Delaware Department of Services for Children, Youth and Their Families Residential Settings
(Institute for Public Administration, 2023-12) Sherretz, Kelly; Burns, Haley Q.; Haberstroh, Susan; Jordan, Joy V.; Marshall, Sarah; West, Valdese; Sherman, Samiyah
This project was funded by the Delaware Department of Services for Children, Youth and Their Families (DSCYF). The purpose of this project is to review the provision of education for youth in secure residential facilities and to make recommendations related to policy, learning environment, staffing, curriculum, and instruction. To complete this project, IPA staff conducted observations at the secure residential facilities, held interviews with DSCYF staff and leadership, reviewed current policies, and summarized best-practice research in Delaware and other key states for comparison. IPA is committed to working with organizations that engage with, teach, and support vulnerable student populations.
Delaware Workforce Development Board Policy Manual
(Institute for Public Administration, 2024-02) Burns, Haley Q.; Jordan, Joy V.; Sherretz, Kelly; Dykes, Lauren; DeMaio, Jenna
The purpose of the Policy Manual is to support the internal operations of the Delaware Workforce Development Board, ensure the board is fulfilling its mandate, and help the board and staff best serve Delawareans. To complete this project, Institute for Public Administration (IPA) staff conducted best-practice research on other workforce development boards and organizations nationwide; collected, reviewed, and analyzed board policies, both physical and digital copies; and helped uncover potential areas for policy improvements.
Delaware Workforce Development Board Landscape Analysis
(Institute for Public Administration, 2024-04) Burns, Haley Q.; Jordan, Joy V.; Sherretz, Kelly; Dykes, Lauren; DeMaio, Jenna
This project was completed in partnership with the Delaware Workforce Development Board (DWDB) with collaboration from the Executive and Deputy Directors and DWDB partner agencies. The purpose of the landscape analysis is to assess state-level workforce development policies related to DWDB partner agencies and analyze these policies for potential areas of overlap or misalignment. To complete this project, Institute for Public Administration (IPA) staff compiled both federal and state policies related to workforce development and conducted interviews with DWDB partner agencies to better understand the workforce development ecosystem and flow of services.
Ultrastrong magnon-magnon coupling and chiral spin-texture control in a dipolar 3D multilayered artificial spin-vortex ice
(Nature Communications, 2024-05-14) Dion, Troy; Stenning, Kilian D.; Vanstone, Alex; Holder, Holly H.; Sultana, Rawnak; Alatteili, Ghanem; Martinez, Victoria; Kaffash, Mojtaba Taghipour; Kimura, Takashi; Oulton, Rupert F.; Branford, Will R.; Kurebayashi, Hidekazu; Iacocca, Ezio; Jungfleisch, M.

Strongly-interacting nanomagnetic arrays are ideal systems for exploring reconfigurable magnonics. They provide huge microstate spaces and integrated solutions for storage and neuromorphic computing alongside GHz functionality. These systems may be broadly assessed by their range of reliably accessible states and the strength of magnon coupling phenomena and nonlinearities. Increasingly, nanomagnetic systems are expanding into three-dimensional architectures. This has enhanced the range of available magnetic microstates and functional behaviours, but engineering control over 3D states and dynamics remains challenging. Here, we introduce a 3D magnonic metamaterial composed from multilayered artificial spin ice nanoarrays. Comprising two magnetic layers separated by a non-magnetic spacer, each nanoisland may assume four macrospin or vortex states per magnetic layer. This creates a system with a rich 16N microstate space and intense static and dynamic dipolar magnetic coupling. The system exhibits a broad range of emergent phenomena driven by the strong inter-layer dipolar interaction, including ultrastrong magnon-magnon coupling with normalised coupling rates of Δf/ν =0.57, GHz mode shifts in zero applied field and chirality-control of magnetic vortex microstates with corresponding magnonic spectra.
Neighborhood disadvantage is associated with working memory and hippocampal volumes among older adults
(Aging, Neuropsychology and Cognition, 2024-04-24) Wright, Regina S.; Allan, Alexa C.; Gamaldo, Alyssa A.; Morgan, Adrienne A.; Lee, Anna K.; Erus, Guray; Davatzikos, Christos; Bygrave, Desirée C.
It is not well understood how neighborhood disadvantage is associated with specific domains of cognitive function and underlying brain health within older adults. Thus, the objective was to examine associations between neighborhood disadvantage, brain health, and cognitive performance, and examine whether associations were more pronounced among women. The study included 136 older adults who underwent cognitive testing and MRI. Neighborhood disadvantage was characterized using the Area Deprivation Index (ADI). Descriptive statistics, bivariate correlations, and multiple regressions were run. Multiple regressions, adjusted for age, sex, education, and depression, showed that higher ADI state rankings (greater disadvantage) were associated with poorer working memory performance (p < .01) and lower hippocampal volumes (p < .01), but not total, frontal, and white matter lesion volumes, nor visual and verbal memory performance. There were no significant sex interactions. Findings suggest that greater neighborhood disadvantage may play a role in working memory and underlying brain structure.
