Sustainable Sediment Management In Jordanian Dams: Feasibility, Economic Viability, And Agricultural Reuse Potential, Ahmed Al-Taani, Nazem El Radaideh, Wesam Al Kateeb, Fares Howari, Yousef Nazzal, Jibran Iqbal, Abeer Al Bsoul

All Works

Jordan has long faced severe water scarcity, which has significant implications for agriculture, industry, and domestic consumption. This crisis is further exacerbated by climate change, population growth, regional conflicts, and unsustainable water use. In response, Jordan has focused heavily on dam construction to secure water supplies, despite the high financial and environmental costs. However, rapid sedimentation threatens dam storage capacity and operational efficiency, reducing their lifespan and long-term sustainability. This study evaluates the feasibility of sediment removal as an alternative to constructing new dams, considering environmental, technical, agricultural, and economic factors. The research is based on case studies from King …

The Impact Of Adult Awareness Of Climate Change On Renewable Energy Consumption In The United States, Mohammad Ismayl Al Masud

SACAD: Scholarly Activities

I conduct a survey among college students in Texas to assess their willingness to pay for renewable energy to tackle climate change. An individual with a good level of climate awareness is 9.38% more willing to pay extra for renewable energy. Comparably, people with an excellent level of awareness are 23% more likely to financially favor renewable energy than others, given the willingness to pay those with a good level of awareness. Utilizing the ARDL model, I analyze the national-level data to extrapolate the individual-level results on a macroeconomic level. I find that a 1% increase in awareness level would …

The Binding Of Cu2+ To Lipid Membranes Is Not Substantially Influenced By Electrostatic Screening, Christopher M. Reynolds, Olivia C. Fiebig, Alexa Marroquin, Andrew J. Glaid, Kushaal Chokhany, Ryan G. Zdenek, Maria Laura Da Cruz Garcia, Paul S. Cremer

Chemistry: Faculty Publications

Gouy-Chapman theory predicts that salt screening and modulating the interfacial charge density should strongly influence the apparent dissociation constant, Kd,app, between Cu²⁺ and negatively charged phosphatidylserine (PS) lipids in supported lipid bilayers (SLBs). Specifically, Kd,app would be expected to increase (weaken binding) by a factor of 40 when 100 mM NaCl is introduced into the solution because of electrostatic screening between the membrane and Cu²⁺ cations. Surprisingly, however, fluorescence quenching measurements demonstrate that Kd,app increases by less than a factor of 2 when increasing the salt concentration in the presence of standard buffers, such as tris(hydroxymethyl)aminomethane (Tris). Moreover, …

Determinants Of Interorganizational Employee Mobility: Systematic Literature Review, Iva Zdrilić, Petra Došenović Bonča, Darija Aleksić

Economic and Business Review

This article provides a comprehensive overview of the determinants of interorganizational employee mobility and proposes their multilevel typology across different sectors and industries. We conduct a systematic literature review of 158 papers in this field. Our results show that some determinants of employee mobility also appear as mobility effects, closing the ``determinants–interorganizational employee mobility–effects'' circle. They also show a hierarchy among mobility determinants, different types of interorganizational mobility, and different effects when mobility occurs between competing and cooperating organizations. This study primarily contributes to the career development literature, which recognizes interorganizational mobility as the primary mechanism for achieving individual work–life …

Meeting Carbon Dioxide Removal Demand In 2030: The Potential Of Macroalgae Cultivation And Harvest, Lotta Siebert, Jiajun Wu, Lena-Katharina Bednarz, David Keller, Felix Meier, Christine Merk, Sonja Peterson, Wilfried Rickels

Journal of Ocean and Coastal Economics

A growing number of countries have announced net-zero and net-negative emissions targets, but only a few countries provide incentives for carbon dioxide removal (CDR). We derive estimates of countries' hypothetical demand for CDR in 2030 based on their emissions reduction targets under the Paris Agreement. The aggregated average global demand for CDR in the compliance year 2030 is 1064 MtCO₂, 353 MtCO₂, and 124 MtCO₂ for the low, medium, and high-cost CDR scenarios, respectively. This demand comes exclusively from countries and regions with relatively high GDP per capita, relatively high abatement costs and a limited …

From Drought To Disparity: Navigating Relief And Barriers For Vulnerable Farmers In The Western Us, Kyla Fugate, Shae Olsen

UM Graduate Student Research Conference (GradCon)

As climate change intensifies, United States Department of Agriculture emergency programs provide crucial relief during crises. Yet, programs like the Livestock Forage Program (LFP) are now being triggered each year as droughts become routine in the western US. Simultaneously, the most climate vulnerable farmers are largely left out of these programs. We examine how institutional structures, program design, and implementation practices shape access to public agricultural support services in the western US, with particular focus on beginning and socially disadvantaged farmers (BSDFs). Drawing from nearly 50 in-depth interviews with USDA staff and farmers across western states, our two papers work …

Understanding the capacity of forests to adapt to climate change is of pivotal importance for conservation science, yet this is still widely unknown. This knowledge gap is particularly acute in high-biodiversity tropical forests. Here, we examined how tropical forests of the Americas have shifted community trait composition in recent decades as a response to changes in climate. Based on historical trait-climate relationships, we found that, overall, the studied functional traits show shifts of less than 8% of what would be expected given the observed changes in climate. However, the recruit assemblage shows shifts of 21% relative to climate change expectation. …

Plural Water Narratives: An Environmental Justice Lens On A Systematic Review Of Q-Methodology Water Research, Melissa Haeffner, Alida Cantor, Janet Cowal, Andrea Bryant, Darius Mani Yaw, Kinna Je Palacios, Daniela Serna, Bryce Sprauer, Abigail Tran-Gruver

Environmental Science and Management Faculty Publications and Presentations

Environmental justice research has shown that people's experiences and perceptions of water differ because systematic inequalities shape the extent to which people access clean water and are exposed to water hazards. Q‐methodology is one technique that has been used to aggregate multifaceted subjective narratives and understand different perspectives on a topic. In this paper, we systematically review 77 case study articles applying Q‐methodology to water‐related topics, to inventory how people perceive their relationships with water. We create a classification system based on environmental justice theory to examine (1) distributive justice issues around alternative water sources and agricultural and urban water …

Exploring The Dynamics Of Lotka-Volterra Systems: Efficiency, Extinction Order, And Predictive Machine Learning, Sepideh Vafaie, Deepak Bal, Michael A.S. Thorne, Eric Forgoston

School of Computing Faculty Scholarship and Creative Works

For years, a main focus of ecological research has been to better understand the complex dynamical interactions between species that comprise food webs. Using the connectance properties of a widely explored synthetic food web called the cascade model, we explore the behavior of dynamics on Lotka-Volterra ecological systems. We show how trophic efficiency, a staple assumption in mathematical ecology, affects species extinction. With clustering analysis, we show how straightforward inequalities of the summed values of birth, death, self-regulation, and interaction strengths provide insight into which food webs are more enduring or stable. Through these simplified summed values, we develop a …

Quantifying Teaching Quality In University Chemistry Using Bipolar Neutrosophic Decision-Making Framework, Lina Sun, Feng Yi

Neutrosophic Sets and Systems

There is no doubt that the teaching of university Chemistry plays a critical role in enriching the students’ knowledge with analytical and problem-solving skills that are necessary for achieving academic and professional progress in many fields. However, the process of evaluating the quality of Chemistry teaching remains a challenging task because it usually relies on subjective judgments, diversity of criteria, and variability in human perception, leading to inherent uncertainty. Bipolar Neutrosophic Sets (NS) provide appropriate representation for uncertainty setting ls with three levels of membership, each with positive and negative degrees. Inspired by that, this study contributes to the body …

Proof Of Concept: Using Uas Technology To Accomplish Aerial Roof Inspections, Madison R. Fanning

Theses and Dissertations

With the growing use of simulation across industries, the digital twin remains an underexplored research area, particularly in emergency management and response. Its real-time updating capability is often overlooked due to the misconception that "digital twin" is merely a complex term for simulation. This paper highlights its distinctiveness through an evasion exercise involving two independent entities in a collocated environment. Using a highly integrated virtual environment (HIVE) and internet of things (IoT) devices, we link the physical system with an analytical simulation, demonstrating the impact of lag times in high-pressure scenarios. The computational model leverages agent-based modeling (ABM) and discrete-event …
