Characterizing Fish Communities Using Traditional And Emerging Monitoring Approaches In San Diego County Estuaries, Natalie Katherine De Wet

Theses

Fish communities are essential to estuarine health, playing key roles in food webs, nutrient cycling, and ecosystem functioning. However, the persistence of native fish populations is increasingly threatened by the cumulative impacts of coastal development, pollution, and climate change. Rapid, effective monitoring of species distributions is a priority, enabling timely conservation and management. However, the study of any ecosystem is limited by time, resources, and the consideration that research of a system can damage the ecosystem under study.

This research aimed to characterize fish species richness and evaluate the benefits and limitations of different estuary monitoring approaches. Specifically, this study …

Global Commons, Local Crises: The Ecological Embeddedness Of Global Production Networks, Christopher R. Whynacht

Graduate Doctoral Dissertations

Notions of Global Production Networks (GPNs) are popular approaches to studying the complex, dispersed, and socially embedded production of goods and services. Yet, these concepts have largely struggled with incorporating environmental resources, risks, and actors. My dissertation leverages insights from Actor-Network Theory (ANT) to contextualize ecological elements of production as coequal participants with social stakeholders. I describe how GPNs are ecologically embedded and nested within the natural environment. I draw from ANT to develop a GPN framework that internalizes ecological dimensions. The second chapter in this dissertation develops these ideas and provides theoretical framing for further empirical chapters. The third …

Effect Of Seasonal Variability In Methane Emissions And Iron Redox Chemistry At Terrestrial-Aquatic Interfaces, Hermes C. Ruiz

Master's Theses

Methane (CH₄) emissions at terrestrial–aquatic interfaces (TAIs) are significant contributors to the global carbon budget, yet the mechanisms driving methanogenesis remain poorly understood. Limited data exist on how seasonal variations and redox processes influence CH₄ fluxes in these dynamic ecosystems. This study addressed two questions: (1) How are CH₄ fluxes in riverine floodplains and adjacent hillslopes impacted by seasonal variations? (2) What roles do metal redox processes (e.g., iron (Fe)) play in regulating methanogenesis?

In-situ CH₄ flux and solid-phase Fe speciation were quantified in East River, CO, under flooded and drained conditions. Groundwater chemistry, gas flux, and soil physical properties …

A Comparison Of A Hyper-Heuristic And An Ea On The Portfolio Optimisation Problem, Rahul Soni, Matthew Craven, David Walker

School of Engineering, Computing and Mathematics

We analyse a selection hyper-heuristic (SHH) and NSGAII for the multi-objective cardinality constrained portfolio optimisation problem, an NP-hard problem addressing the asset allocation trade-off between return and risk under constraints of the number of assets. We evaluated the performance of the SHH and NSGA-II for cardinality constraints K = {2, 5}. Our results are competitive with those of NSGA-II.

Compound-Specific Isotope Records Of Dust Provenance And Hydroclimate In The North Pacific And Marginal Seas Of East Asia: Integrating N-Alkane Δ13c And Δd With Standardized Analytical Frameworks, Julian W. Traphagan

LSU Doctoral Dissertations

This dissertation presents advancements in compound-specific isotope analysis (CSIA) through methodological innovation and paleoclimate reconstruction in Central and East Asia.

Penerapan Pembelajaran Dilatasi Dengan Pendekatan Kontekstual Berbasis Etnomatematika, Axellya Dian Prastica, Tamyis Suliantoro, Santi Irawati

Journal of Innovation and Teacher Professionalism

Mathematics learning is often perceived as disconnected from students’ real lives, which can reduce their interest and understanding. To address this problem, an ethnomathematics-based contextual approach is needed to connect mathematical concepts with local culture and students’ everyday experiences. This study aimed to analyze the effects of teaching dilation through an ethnomathematics approach on the understanding and learning motivation of eighth-grade students. An experimental method with a pretest–posttest design was used, involving 30 students. Data were collected through achievement tests and a learning motivation questionnaire and were analyzed using descriptive and inferential statistics.

Determination Of Excess Pore Pressure In Under Consolidating Soil By Using Cptu, Karolina Villa Delfia Ihut, Martin Wijaya, Aswin Lim, Alfrendo Satyanaga, Grisella Aglia, Sharfina Faradiba Syifanaya, Andy Sugianto

Makara Journal of Technology

North Jakarta is predominantly composed of soft soil that is still undergoing consolidation. According to research by Raharjo et al. (2022), excess pore pressure is still present in the soils of Jakarta. The degree of consolidation and excess pore pressure values indicate that consolidation is not yet complete (Raharjo et al., 2022). In this study, the researchers developed two methods to determine excess pore pressure using field testing. The Stress History and Normalized Soil Engineering Properties (SHANSEP) model equation from Ladd and Foot (1974), as well as Finite Element Method (FEM) modeling using the PLAXIS program, were utilized …
