Application Of Distributed Fiber Optic Sensing (Dfos) For Monitoring Asphalt Pavement Strains Under Accelerated Loading Conditions, Sebastian Morales

Open Access Theses & Dissertations

This thesis presents a study on the application of Distributed Fiber Optic Sensing (DFOS) technology for detecting pavement's strain response with high spatial resolution. Using a Rayleigh-based optical frequency domain reflectometry (OFDR) system, DFOS sensors were calibrated and embedded in full-scale asphalt slabs subjected to accelerated loading using a Model Mobile Load Simulator 3 (MMLS3). Calibration of the DFOS sensors was conducted using a three-point bending flexural test with known load conditions and reference strain gauges to validate theoretical and numerical models. The results demonstrate DFOS's capability to detect pavement response under static and dynamic loading, as well as changes …

Temporal Partitioning And Coexistence Among Four Sympatric Felid Species In The Northern Jaguar Reserve, Kylie Marie Rezendes

Open Access Theses & Dissertations

Coexistence among sympatric carnivores is shaped by behavioral strategies that mediate competition and mortality risk in heterogeneous landscapes. Understanding how sympatric carnivores, such as felids, use space and time in relation to one another requires models that account for both spatial and temporal overlap across landscapes. Models incorporating time-to-event probabilities provide a powerful framework for detecting behavioral dynamics across shared landscapes. This study evaluated the spatiotemporal responses of two apex predators â?? the jaguar (Panthera onca) and mountain lion (Puma concolor) - and two mesopredators - bobcat (Lynx rufus) and ocelot (Leopardus pardalis) - across five years of camera trap …

Roles Of Three Conserved Active Site Residues Of Cytochrome C Nitrite Reductases During The Early Steps Of Nitrite Reduction, Shahama Alam, Bradley J. Dimock, Brian Bennett, Steven J. Reinhardt, Shahid Shahid, A. Andrew Pacheco, Jarett Wilcoxen

Physics Faculty Research and Publications

Cytochrome c nitrite reductases (ccNiRs) catalyze reduction of nitrite to ammonium in a six-electron, eight-proton process. This report explores how the behavior of three active site ccNiR variants differs from that of the wild type enzyme (ccNiR_wt) in the presence of nitrite and a variety of electron donors. While the nitrite-loaded active site of Shewanella oneidensis ccNiR_wt could be 2-electron reduced within seconds to yield a 6-coordinate ferrous nitrosyl ({Fe(L)NO}⁷) at high applied potentials, quantitative reduction of the nitrite-loaded variants R103Q, H257Q, or Y206F required substantially stronger reductants and yielded a different product over several …

Listening As An Adaptive Practice To Transform Philanthropy, Nitya Venkateswaran, Kate Szczerbacki, Jay Feldman

The Foundation Review

A growing number of grantmaking institutions (GMIs) recognize that listening to communities in which they invest—especially those to, and most affected by, the challenges being addressed—is crucial to achieve their equity goals. Despite investments and intent to listen, there is a gap in implementation.

Genuine listening for equity requires that foundation leaders view the shift as adaptive and not merely technical. A technical change entails adoption of specified methods whereas adaptive changes require a fundamental shift in values and beliefs. Solely implementing new “listening” techniques without shifting values and beliefs could leave gaps between intention and action. But current resources …

Funder Listening To Shift Power: Definitions And Context, Melinda Tuan, Rick Moyers, Gita Gulati-Partee

The Foundation Review

Listening in the context of philanthropy is a common colloquial term that can have many definitions, ranging from everyday conversations that inform foundation work to more formal opportunities for community engagement. Most foundations say they listen, but all forms of listening are not equally beneficial, and listening alone does not inherently advance equity. Listening, done poorly, can be performative and extractive. Listening well, in ways that advance equity, is done in partnership, requires a response from the listener to acknowledge what’s been heard and what will be done as a result, and ultimately shifts power to the community.

Community Engagement: A Core Practice On The Journey To Power Sharing, Elizabeth Jordan, Tryphena A. Clarke, Raquel R. Robinson

The Foundation Review

In this article, the authors posit that equity and power-sharing are foundational considerations for responsible philanthropy given the inherently unequal balance of wealth. These considerations may be magnified for family and place-based foundations where philanthropy has an outsized impact within a particular community.

Community engagement is a core practice tied to equity and power-sharing that can bring philanthropy into closer alignment with democratic and social equity values. This article examines the 15-year journey of a place-based family foundation as a reflection on how grantmaking organizations may shift their governance, giving priorities, staffing model, and operating practices to support the tenets …

Listening And Participation Prime Funders To Honor And Build Community Ownership, Gita Gulati-Partee, Katy Love

The Foundation Review

Funder listening is an essential complement to community participation to disrupt white dominant culture habits that entrench the status quo of hierarchy and power. Community-centered listening, combined with participatory processes, offers funders an opportunity to shift in deep and sustainable ways from an individualistic, “power over” orientation to interdependent relationships with community partners.

In this article, two practitioners of equity and participatory philanthropy share how funder listening and community participation form a potent combination to help funders confront their own power and use it intentionally to honor and bolster community ownership and agency.

Drawing on the authors’ direct experience, this …
