Building Resilience To Public Safety Power Shutoffs Through Public Education, Vikram Koundinya, Cristina Chiarella, Susan Kocher, Faith Kearns, Sabrina Drill

Journal of Extension

Public Safety Power Shutoff events are being implemented in California to reduce wildfire impacts. We surveyed California residents to identify their information needs and understand the potential role of University of California Cooperative Extension (UCCE) in power shutoff management. A majority of respondents need information on alternative power sources and community power systems. Most respondents indicated family, friends, and neighbors as the important group to manage power shutoff. UCCE was least used and preferred source for power shutoff information. Our findings reveal a need for Cooperative Extension to play an important role in power shutoff management and educating the public.


Clark Moustakas’ Husserl, Thomas Byrne Feb 2025

Clark Moustakas’ Husserl, Thomas Byrne

The Qualitative Report

This paper critically examines Clark Moustakas’s presentation of Husserl in Phenomenological Research Methods. I argue that Moustakas’s account misrepresents two core elements of Husserl’s phenomenology – intentionality and the transcendental reduction – in ways that directly compromise the foundations of qualitative phenomenological research. First, Moustakas treats intentional meaning as something private, located within the individual, rather than as given in the world. This misreading severs the connection between experience and a shared world of meaning, leaving qualitative researchers unable to clarify participants’ accounts beyond private expression. Second, Moustakas reduces the transcendental reduction to introspective reflection, overlooking its function as a …


Offal Wildlife Watching: Connecting Hunters, Wildlife Researchers, And The Public Through Participatory Science, Ellen M. Candler, Grace Milanowski, Amy Rager, Joseph K. Bump Feb 2025

Offal Wildlife Watching: Connecting Hunters, Wildlife Researchers, And The Public Through Participatory Science, Ellen M. Candler, Grace Milanowski, Amy Rager, Joseph K. Bump

Journal of Extension

Offal Wildlife Watching is a participatory science project that engages deer hunters in wildlife research. The goal of the project is to better understand the ecology of scavenger species that visit deer gut piles across Minnesota. We asked hunters to deploy remote cameras at white-tailed deer gut piles that resulted from their freshly killed deer. Thus far 117 hunters have contributed images and recorded at least 49 different scavenger species. This project is a natural fit in Extension programs and can easily be adapted to other hunted species, biomes, and locations.

TeV halos are extended very-high-energy (VHE; 0.1-100 TeV) gamma-ray emission around middle-aged pulsars. So far, they have only been found around isolated pulsars, but it has been suggested that they may also be powered by millisecond pulsars (MSPs). We searched for VHE gamma-ray emission from MSPs reported by radio and GeV gamma-ray observatories in 2565 days of data from the High-Altitude Water Cherenkov (HAWC) Observatory. We found no significant emission from individual pulsars. By combining the likelihood profiles of all MSPs accessible to HAWC, our analysis suggests that the excess emission around the MSP population is consistent with a background. …

De-Dollarization And South Asia: Challenges And Opportunities For Nepal In A Multipolar Currency World, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

The United States dollar’s dominance as the global reserve currency, established under the 1944 Bretton Woods system, persists despite the 1971 decoupling of the gold backing to the dollar. Its liquidity, stability, and full support by the US government confer a solid financial security and advantage to the currency, including a universal acceptance of the dollar and a relatively low borrowing cost. Because of these reasons, the US dollar has been able to dominate the global financial markets for the past eight decades. However, the rapidly emerging global political and economic power shifts are challenging the status of the US …

An Inventory Of Private Well Programs Across The United States, Bethany G. Foust, Ann S. Ojeda, Jessica Curl, Eve Brantley, Stephanie R. Rogers

Journal of Extension

Private well owners comprise approximately 15% of the United States (US) population and are responsible for managing their well water. Management of domestic wells can be burdensome, requires knowledge, and is critical for maintaining clean drinking water. Management resources vary by state and the resource landscape across the US is unclear. Thus, our objective was to inventory where resources exist, while also highlighting geographic areas that may need improved resources to ensure that people have the ability to safely manage their drinking water. Results of this inventory showed that 64% of states have programs; 72% of which were Cooperative Extension.

The peculiarities of copyright in the metaverse lie in two main challenges: firstly, copyright in the virtual world is usually …


The Hypocrisy Behind The Absolute Banning Of Torture: Historical Fallacies, Factual Necessities, And Judicial Artifices, Abdelalim Morsy Feb 2025

The Hypocrisy Behind The Absolute Banning Of Torture: Historical Fallacies, Factual Necessities, And Judicial Artifices, Abdelalim Morsy

Theses and Dissertations

The absolute and non-derogatory prohibition of torture is embedded in almost every international or regional human rights instrument that deals with civil rights. However, this ban witnesses a diversion between theory and practice. While this diversion is comprehendible in authoritarian states, democratic regimes also implement it in some instances. This usage notably arose in the wake of the 11th of September 2001 and the accompanying usage of physical coercion in the interrogation processes. Simultaneously, some scattered, though notable, scholarly voices started challenging the absolute prohibition against torture. This pro-torture school of thought echoed in some legislative and executive works. The …

Supporting Egypt's Industrial Decarbonization: The Role Of Dfis In Cbam Alignment, Malak Elsaid

Theses and Dissertations

The European Union’s (EU) Carbon Border Adjustment Mechanism (CBAM) introduces a new linkage between trade and climate policy by requiring importers to report and pay for embedded emissions. For Egypt, characterized by high trade exposure to the EU through the export of carbon-intensive products, CBAM serves as a regulatory catalyst for industrial transformation, posing significant competitiveness risks. Recent assessments indicate that the Middle East and North Africa (MENA) region faces a significant CBAM burden, approximately three times that of other emerging market and developing economies.

Utilizing the Institutional-Capacity Response Model as an analytical tool, this study examines how such external …


Understanding The Accuracy And Best Use Of The Woodland Stick As A Tree Height And Diameter Measurement Tool: A Case Study In Oregon, Francisca Belart, Lauren Grand, Alicia Christiansen Feb 2025

Understanding The Accuracy And Best Use Of The Woodland Stick As A Tree Height And Diameter Measurement Tool: A Case Study In Oregon, Francisca Belart, Lauren Grand, Alicia Christiansen

Journal of Extension

We conducted a study to assess the accuracy of the Woodland Stick in determining tree diameter and height as compared to professional measurements and how bias can affect tree volume calculation. After comparing professional measurements with five non-professionals (NP’s) using the Woodland Stick, we found that three out of five NP’s had significant differences in mean dbh, and all of the NP’s had significant differences in mean total height. The overall bias for dbh across users was +0.5 inches and +5.1 ft for height. These deviations can result in volume differences between 0 and 30 bf on a single tree.

Youth Public Speaking Self-Efficacy Survey Tool, Roshan Nayak, Steven M. Worker, Nicole Marshall-Wheeler

Journal of Extension

Extension has a role to play in workforce development by preparing the next generation to be successful communicators. While Extension 4-H youth programs have contributed to public speaking development since their inception, there has not been a validated instrument to assess young people’s public speaking self-efficacy. We utilized an iterative-scale development process to develop, test, and refine such a tool. We hope youth development professionals will consider using the Youth Public Speaking Self-Efficacy (PSSE) survey tool to measure and report youth’s PSSE skills, along with the sources influencing these skills, to help with program planning, implementation, and professional development activities.

Inadequate Intensification Of Ldl-Cholesterol Lowering Therapy After Coronary Revascularization: Insights From The Gould Registry, James A De Lemos, Robert S Rosenson, Mikhail N Kosiborod, Christopher P Cannon

Faculty, Staff and Students Publications

Background: Patients with a history of coronary revascularization are at a higher risk for subsequent cardiovascular events and all-cause mortality. Lowering LDL-cholesterol (LDL-C) levels post-revascularization significantly reduces these risks.

Methods: This analysis compared LDL-C-lowering therapies at baseline and over time among patients with and without prior coronary revascularization in the GOULD registry (a prospective multicenter cohort study). Baseline- and 24-month follow-up characteristics-including LDL-C levels and strategies for lipid-lowering therapy (LLT)-were evaluated.

Results: Out of 5006 patients, 2195 (43.8%) had prior coronary revascularization. At baseline, these patients had lower LDL-C (99.2 mg/dL vs. 102.5 mg/dL; p < 0.001) and were more likely to be on intensive LLT (52.8% vs. 42.7%; p < 0.001). At 24 months, they had small reductions in LDL-C (-15.6% vs. -13.7%; p = 0.145) and were more likely to be on intensive LLT (61.9% vs. 51.5%; p < 0.001). Similar LDL-C reductions were observed in the PCSK9i group regardless of revascularization status.

Conclusions: Despite slightly better baseline …
