    What’s Guiding Chemical Engineering?: A LibGuide Content Analysis (Presentation)
    (2026 ASEE Annual Conference & Exposition, 2026) Weiss, Sarah
    Background LibGuides are a commonly used tool for aggregating library resources by topic. While their use is practically ubiquitous in academic libraries, the content and pedagogical approach of these guides vary widely. This is the first such published content analysis of LibGuides in the field of chemical engineering. Purpose/Hypothesis The research explores current trends in the composition of chemical engineering LibGuides including the resources most commonly presented as well as pedagogical approaches to presenting information. Method/Design/Scope While this research initially was designed with a broader scope, in its current state it presents a comprehensive analysis focusing specifically on chemical engineering LibGuides. This study considers guides from 50 of the R1 institutions listed in US News and World Report 2023-2024 Best Engineering Schools. Each guide analyzed was saved as a PDF in the summer of 2024 and uploaded to NVivo for coding of the layout, content, and pedagogy used in the guide. This subsequent data collected was then exported to Excel for clean up and analysis. Results/Conclusions The analysis results show evidence of patterns in content and pedagogical approach in chemical engineering LibGuides at R1institutions. Most notably, there is a level of consistency in the types of resources presented, particularly databases and reference works suggesting some shared disciplinary norms among engineering librarians regarding core research resources. This information is useful for those with limited knowledge in the area or those looking to create research guides or other instructional materials to support chemical engineering programs. This analysis does have limitations including being discipline limited and not addressing issues of best practice areas which could be the focus of further research.

    A Guide to Change Management Using the SARAH Model (Poster & Supplemental Materials)
    (2026) Kern, Sara; Barbrow, Sarah; Jane Dooley, Sarah; E Lester, Sarah; Over, Sarah; Weiss, Sarah
    Academic libraries are the heart of colleges and universities and, as such, are often centrally involved in and impacted by changes in the greater higher education landscape. For those working in these spaces, familiarity with strategies for managing change is essential to support yourself and others during especially turbulent times. The SARAH model, described below in bullet points with our modifications in brackets, offers a memorable way to understand responses to change, be they our own or others. S - Shock or Surprise A – Anger [Anxiety, Alert, or Anticipation] R – Resistance or Rejection [Re-engagement, or Rationalization] A - Acceptance H - Help or Hope This is not an inevitable cycle and some people may not move through the stages in a linear manner. The existing model offers structure, but our addition adds flexibility, opportunities for positive reactions, and library-specific examples and context. This model, and our modifications to it, helps individuals identify their own or others reaction to change, recognize where they might be in the process, and respond with empathy and support. By understanding feelings and reactions of ourselves and others, we can provide thoughtful and intentional support during difficult times. United by their shared name, the Sara(h)s of ELD bring together their diverse experiences and perspectives to present the SARAH model for use in academic libraries, and particularly for those working with Engineering or STEM departments. This paper and poster will present the SARAH model alongside strategies and examples for supporting both yourself and others when managing change in a library context.

    Selecting DNA Aptamers Against Airway Mucin Protein for Therapeutics and Diagnostics
    (2026) Rodriguez, Anasophia; Sidhu, Manroop; Ustundag, Defne; Spirito, Catherine
    Selecting DNA Aptamers Against Airway Mucin Protein for Therapeutics and Diagnostics Mucus is a viscous bodily fluid whose primary protein makeup is composed of the mucin proteins MUC5AC and MUC5B. Elevated levels of MUC5AC in airway mucus is implicated in diseases such as asthma, cystic fibrosis (CF), and chronic obstructive pulmonary disease (COPD). Current treatments to clear mucus use enzymes or chemical agents; however, they are nonspecific and can cause adverse side effects. Our research aims to select and characterize DNA aptamers that strongly and specifically bind to MUC5AC for diagnostic and therapeutic applications. Aptamer selection is done via One-Pot SELEX, in which the MUC5AC is immobilized on the walls of a PCR tube, incubated with a guanine and cytosine rich DNA library, and then amplified using a 5’ phosphorylated reverse primer. The current aptamer selection pool is binding to both MUC5AC and MUC5B samples, indicating the need for increased negative selection steps during One-Pot SELEX. We are using thrombin and its aptamer to optimize gel shift assays and nitrocellulose filter assays, with the end goal of characterizing the binding affinity of aptamers candidates to MUC5AC. In the future, we aim to identify and characterize DNA aptamers with strong affinity and specificity for airway mucin proteins to support therapeutic strategies that deliver engineered proteases to cleave them.
