Linking Fishery Productivity To Child Health In The Coastal Tropics, Francisco Flores-Mejia

Master's Theses

Fish are a primary source of calories, macronutrients, and income for coastal communities around the world, but overfishing and environmental changes have dramatically reduced productivity in the majority of small-scale fisheries. The social costs of these losses are believed to be large, particularly in poorer communities, but most estimates of fishery productivity effects on households are contextual and difficult to generalize. We combine a remote sensing measure of pelagic fishery productivity with geolocated child health and growth data from 34 countries in the coastal tropics. We estimate that the difference between sustainedly good versus bad fishing conditions corresponds up to …

Deforestation Dynamics In The Amazon: Impacts, Socio-Environmental Drivers And Restoration Pathways, Maria Natalia Rodriguez

Master's Projects and Capstones

The Amazon, which is the largest tropical rainforest in the world, experienced 542,581 km² of forest loss between the years 2000 and 2020. The process of deforestation endangers the ecological system results which maintain ecosystem connectivity and the Earth's climate system. The Amazon rainforest supplies essential ecological services which include maintaining soil fertility, storing carbon, purifying water and climate stability. The fundamental ecosystem of this area faces new threats because of increasing forest destruction. The research study adopts a combined methodology that uses Geographic Information Systems (GIS) with a comprehensive literature review to study Amazon deforestation patterns and its driving …

Climate-Driven Maritime Hazards And Marine Fuel Oil Spill Risk In The Northwest Passage, Emily Grace Parker

Master's Projects and Capstones

Shipping activity across the Northwest Passage has increased by 46% since 2011 as climate forcing drives sea ice decline, but associated risks to vessels and the environment are underestimated and rarely examined together. A literature review conducted in this study indicated that by 2070, a 5-month navigation window will expose vessels to increasingly unpredictable hazards as the region transforms from an ice- to wave-dominated regime, with wave heights increasing by 10-13% per decade. Ice hazards persist, and vessels operating in early summer and late fall will be exposed to elevated ice accretion risk that can cause capsizing and marine fuel …

Effectiveness Of Wastewater Treatment Technologies For Pharmaceutical Removal In Bogotá, Colombia, Lady Palomino

Master's Projects and Capstones

Pharmaceutical compounds are increasingly detected in urban water systems worldwide, posing significant ecological and public health risks in cities where wastewater treatment infrastructure is insufficient to remove them. This study evaluates the presence of pharmaceutical compounds in Bogotá's wastewater systems, the effectiveness of current treatment technologies for their removal, and the regulatory and monitoring gaps that hinder their management as emerging contaminants of concern. A systematic literature review was conducted to assess the occurrence of pharmaceuticals in municipal and hospital wastewater, as well as in effluents from wastewater treatment plants (WWTPs) and receiving surface waters in Colombia, with particular focus …

Soil Dna-Phosphorus: Method Optimisation And Application Across Uk Soils, Margaret Massam, Daniel Menezes-Blackburn, Mohammed Al Kasbi, Catherine Wearing, Marc Stutter, Courtney D. Giles, Tegan Darch, Timothy S. George, Charles Shand, David Lumsdon, Martin Blackwell, Hao Zhang, Patricia Cooper, Renate Wendler, Lawrie Brown, Philip M. Haygarth

Journal of Agricultural and Marine Sciences

Despite growing recognition of rapid diester P turnover, quantitative data on soil DNA-P across soil types remain scarce due to methodological constraints. This study aimed to investigate the impact of changes in the analytical protocol of a soil DNA-P method developed by Paraskova et al. (2013) on DNA-P recovery and the use of the revised procedure on 32 UK soils on our understanding of DNA-P in soils. The steps of the Paraskova method were tested on two contrasting soils, and a revised version was developed and used to determine the DNA-P levels of 32 UK soils. These findings were then …

The synergistic application of biochar and nitrogen fertilizer significantly improves plant growth and soil properties. The present study aimed to evaluate the effect of the application of biochar and nitrogen on the shoot and root of lemongrass in a factorial design within a completely randomized setup. The experiment included three levels of biochar, i.e. 0%, 1%, and 2% (v/v) and 2 levels of nitrogen, i.e. 0 and 1 (g/pot) under greenhouse conditions with 3 replications. The following parameters were measured, plant height, number of tillers, number of leaves, length of the largest leaf, fresh, shoot and root dry weight. The …

Ai-Driven Plant Health Assessment And Remediation: Case Study On Lemon Plants And Witches' Broom Disease, Zuhoor Al-Khanjari, Misk Hersi, Zainab Al-Ajmi

Journal of Agricultural and Marine Sciences

Plant diseases pose significant challenges to agricultural productivity and food security, particularly in regions like Oman, where citrus crops, such as lemon trees, are economically vital. Traditional diagnosis methods are time-consuming and often require expert intervention, limiting accessibility for small-scale farmers. This paper presents an AI-driven plant health assessment Nuwriq application. It leverages both image-based and text-based input to diagnose lemon plant diseases, particularly the Lemon Witch Broom Disease (LWBD). It incorporates two machine learning models: a convolutional neural network (CNN) for image classification and a natural language processing (NLP) model for symptom-based textual analysis. Users can upload images of …

Antagonistic Bacterial Isolates Derived From Salt Cedar (Tamarix Nilotica) Suppress Pythium Aphanidermatum Damping-Off In Cucumber Under Glasshouse Conditions, Saba Al-Ghassani, Issa Hashil Al-Mahmooli, Fatma Al-Makhmari, Zainab Al-Balushi, Waleed Al-Busaidi, Mohamed Abdullah Al-Kindi, Khalid Al-Farsi, Abdullah Mohammed Al-Sadi, Rethinasamy Velazhahan

Journal of Agricultural and Marine Sciences

Cucumber (Cucumis sativus L.) damping-off, which is caused by the soilborne oomycete Pythium aphanidermatum, is an extremely damaging disease. An environmentally friendly and safe method of controlling damping-off in cucumber and other vegetable crops is biological control, which employs naturally existing antagonistic microorganisms. In this investigation, bacteria from root tissues (endophytic bacteria) and rhizosphere soil (rhizosphere bacteria) were isolated from Tamarix nilotica (Tamaricaceae), commonly known as salt cedar, and their potential to inhibit P. aphanidermatum and their efficacy in managing damping-off in cucumber under controlled glasshouse conditions were assessed. Ten rhizospheric and six endophytic bacteria with different morphological traits were …

Journal of Agricultural and Marine Sciences

The research aimed to forecast the exports of United Arab Emirate (UAE) from date palm during the period (2021-2030). The R programming language was used to conduct econometric analysis in artificial intelligence, by analyzing time series of the factors influencing the UAE date palm export quantity and using the (ARIMA) methodology and construction of the artificial neural network (ANN). The results demonstrated that the influence of independent factors on the quantity of future exports was apparent, including the UAE date palm production quantity in tons (x1) at a percentage of (21.08%), domestic consumption in tons (x2) by (20.69%), mean UAE …

Who Gains And How? Agri-Food Trade Outcomes Of The Oman–India Cepa, Osman Gulseven, Lokman Zaibet, Ibtisam Al-Abri

Journal of Agricultural and Marine Sciences

This research evaluates the agricultural and food-related trade effects of the Oman–India Comprehensive Economic Partnership Agreement (CEPA) using product-level partial-equilibrium simulations implemented through the Trade Intelligence and Negotiation Adviser (TINA) platform. The results based on 2024 trade data indicate asymmetric outcomes. While both partners experience trade gains (\$567 million for Oman and \$656 million for India), Oman's export expansion to India is highly concentrated in a small number of energy and chemical products, whereas India's exports to Oman increase across a wide range of tariff lines, including several food products. In agriculture, CEPA primarily reinforces India's role as a key …

A Governorate-Level Index Of Fisheries And Coastal Habitats In Oman, Ibtisam Al Abri, Jaynab B. Yousuf, Nadir Al-Abri, Fahad Al Rasbi

Journal of Agricultural and Marine Sciences

Oman's fisheries sector, deeply rooted in coastal tradition, is becoming a key pillar in the nation's transition away from oil dependency. With over 3,165 km of coastline and access to three major marine ecosystems, the Arabian/Persian Gulf, Sea of Oman, and Arabian Sea, the country holds vast ecological and economic potential. However, the sustainability and performance of small-scale fisheries (SSF), which represent over 90% of national fishing activity, vary widely across governorates due to environmental stress, infrastructure gaps, and climate vulnerability. This study presents the first governorate-level, multidimensional assessment of fisheries and coastal resources sustainability in Oman. Using a mixed-methods …

The Jurisprudence Of Humanity, Tyler Rose Clemons

Journal of Civil Rights and Economic Development

(Excerpt)

It has become common for Supreme Court Justices—the most powerful legal actors in our society—to explain why “the law” requires them to facilitate, or at least tolerate, terrible human suffering. Such claims are wrong, not just morally but legally. More specifically, they expose the decisions of the Roberts Court as a based on a jurisprudence of nihilism, one that justifies human suffering through vague appeals to the rule of law. These appeals, in turn, thinly conceal a substantive political and moral project.

To support this claim, I proceed in five parts. Part I introduces Albert Camus’s account of nihilism …

Words Matter: The Rhetoric Of National Security And The Reality Of Individual Rights, Christopher J. Borgen

Journal of Civil Rights and Economic Development

(Excerpt)

While the meanings of words can be flexible or contested, they are not infinitely pliable. These limits on words and their uses help define the outer bounds of legitimate state action. However, even the written law is only as stable as our interpretation of what those words mean. There is the risk that a deliberate and persistent misuse of words by states and other actors can eventually change our understanding of the law it.

Some of my work has analyzed the use of words and phrases such as “self-determination,” “sovereignty,” and “secession.” But, in this Essay, I focus on …

Uncovering Discrete States From Multimodal Psychophysiological Data Using Gaussian Latent Dirichlet Allocation (Glda), Congyu Wu, Aaron Fisher, David Schnyer

Northeast Journal of Complex Systems (NEJCS)

In this article we explore and validate the utility of an unsupervised probabilistic model, Gaussian Latent Dirichlet Allocation (GLDA), for discovering discrete states from repeated, multimodal psychophysiological samples collected from multiple individuals. Psychology and medical research heavily involves measuring potentially related but individually inconclusive variables from a cohort of participants to derive diagnosis, necessitating clustering analysis for state identification. Traditional probabilistic clustering models such as Gaussian Mixture Model (GMM) assume a global mixture of component distributions, which may not be realistic for observations from different patients. The GLDA model borrows the individual-specific mixture structure from a popular topic model Latent …

Kicau Kericau: The Chirps And Warbles Of A Bird-Human Story, Airien Ludin

Masters Theses

This thesis tells the tale of bird-human relationships and what it means to live alongside one another, subverting the hierarchical view of humans as above birds inherited from colonial history. It asks how the practice of illustration can function as a site of Two-Eyed Seeing, where scientific and local knowledge are held together as an entangled narrative. It also examines how mendongeng (storytelling), as I have experienced it within Indonesian culture and everyday contexts, can help us understand birds as a companion species with their own agency.

This project takes two forms: first, a picture book titled Sun Bird …

Tùn-Scene And A-Futurism: Biomythography, Opacity, And Posthuman Imagination, Minglu Du

Masters Theses

Grounded in the author’s position as a Chinese feminist, this thesis examines how East Asian women, as well as East Asian-coded femininity more broadly, are objectified and othered within futurist visual culture in the age of artificial intelligence. Through an engagement with ornamentalism, techno-Orientalism, and posthumanism1 , it argues that the persistent figure of the feminized humanoid cyborg continues to reproduce colonial and patriarchal structures of desire, rendering marginalized bodies as fetishized and violable surfaces. In response, the thesis develops Tùn-Scene, a biomythographic artistic framework and the first experiment in what the author provisionally names A-Futurism. Drawing on Donna Haraway’s …

I Miss My Computer: Online Artistry, Web Aesthetics, And Coming-Of-Age In A Digital Landscape, Catherine Capeci

Masters Theses

This thesis explores how young artists develop their creative practices in a world informed by digitality. Through survey research of 44 art students between the ages of 14 and 22, as well as a process of autoethnographic inquiry, I examine how artists in high school and college relate to digital imagery, web archives, online gaming, and social media platforms, and how these experiences inform artmaking. I believe that art educators should explore how the internet informs aesthetic and conceptual sensibilities, and how these sensibilities show up in young artists’ work, more so than focus on digital media as its own …

Soft Bodies, Hard Frames, Emily Zhang

Masters Theses

Silk is delicate yet strong, responsive to light and air, dependent on living processes and careful labor. These qualities position silk not only as a material object, but as an instrument capable of organizing space. Rather than functioning solely as a surface or decorative textile, silk can operate as a spatial generator, shaping enclosure, movement, and environmental conditions.

For centuries, domestic courtyard houses in the Jiangnan region, located south of the Yangtze River, evolved alongside sericulture, forming spaces that were attuned to the environmental and material requirements of silk. Architectural elements such as courtyards, screened openings, flexible interiors, and canal-directed …

Fetishismus:Facism, Sodomy, And The Exhibition, Matthew P. Gershovich

Masters Theses

Fetishismus examines the contemporary dislocation between homosexuality and queerness. Homosexuality is the biological, innate quality of same-sex attraction. Queerness is rooted in deviance, perversion, and sociologically attached to the “other.” Although almost always used in an explicitly homosexual connotation, “queerness” is not entirely contingent on the physical engagement of homosexual acts. In historical usage, queer is used as a pejorative adjective, implying a lack of masculinity with the intent to invoke repulsion. In contemporary parlance the two are treated as synonymous. This intertwined relationship relies on the forced lack of social and spatial belonging that is rooted in a foundational …

The Frame You're Holding, Andrea Mato

Masters Theses

The Frame You're Holding explores how my photographer's eye transitioned into a graphic designer's voice. The projects presented explore how to weave the textural and subjective qualities of photography into a design context. My practice explores how the frames of graphic design – the page of a book, the browser window, or the wall of an exhibition – can be expanded or reimagined. As a designer, I became the translator of content into form, seeking to author the design while collaborating with other voices. The Frame You're Holding is a snapshot of my practice as a graphic designer, encapsulating my …

Looking In All Directions, Abby Sunde

Masters Theses

“Looking in All Directions” mobilizes attention towards the concepts of ‘desettling’ through art and ‘desettling’ as a way of being. Desettling constitutes resistance, resilience, survivance, and refusal of current Western modalities within our society. This body of work is a material exploration of these worldviews to find potential ways to embody a practice that aligns ourselves outside of a colonial settler mindset while living within its societal condition. Using glass, sound, and installation work, the artist un-centers expected encounters with an inherited dominant worldview and instead offers an actualized shift in awareness. Concepts of interconnectedness, interwoven time, and embodied memories …

Insects And Arthropods And Their Role In Human Society, Emily Marie Perez-Medina

Whittier Scholars Program

With brightly colored exoskeletons, an excess of both eyes and legs, and seemingly  unpredictable behaviors, insects and arthropods come across as unusual and strange to general audiences. For this reason, they are often classified as “gross,” “ugly,” or “scary,” antagonists  in popular culture. What is not recognized when being represented to the masses is how much human society depends on their presence, and how a world without insects would be a world without most things humans know and love. In order to help reduce the stigma of these tiny, yet mighty creatures, this project serves as a call to action …

Collecting Meaning: A Study On Collecting As An Artmaking Practice, Johanna Young

Masters Theses

This thesis explores how we practice creativity and construct narratives through the act of building collections. It examines collecting as both an innate creative impulse and a learned process. Using arts-based research and narrative inquiry, the study considers how our collecting habits reflect the ways we process information and express personal artistic interests. Drawing from personal experiences, this thesis mines the idea of the subconscious through the artistic lens of collecting.

Numb., Anna Rapson

Masters Theses

Social media platforms, from their conception, posed a break in the lived experience of the average human being’s day to day routines. Although access to information has always been shaped by portals into other lived realities—through photojournalism, print legacy media, news broadcasts both on radio and television—social media has posited a novel phenomenological architecture where borders between embodied reality and perception of lived experience are simultaneously blurred and reinforced. This morphed duality of consciousness positions the body and mind in tension, deconstructing pre-social media conceptions of the ontology of lived experience. In a digital world shaped by limitless input by …
