From The Ocean To Our Kitchen Table: Anthropogenic Particles In The Edible Tissue Of U.S.. West Coast Seafood Species, Summer D. Traylor, Elise F. Granek, Marilyn Duncan, Susanne Brander Dec 2024

From The Ocean To Our Kitchen Table: Anthropogenic Particles In The Edible Tissue Of U.S.. West Coast Seafood Species, Summer D. Traylor, Elise F. Granek, Marilyn Duncan, Susanne Brander

Environmental Science and Management Faculty Publications and Presentations

Microplastics (MPs) and other anthropogenic particles (APs) are pervasive environmental contaminants found throughout marine and aquatic environments. We quantified APs in the edible tissue of black rockfish, lingcod, Chinook salmon, Pacific herring, Pacific lamprey, and pink shrimp, comparing AP burdens across trophic levels and between vessel-retrieved and retail-purchased individuals. Edible tissue was digested and analyzed under a microscope, and a subset of suspected APs was identified using spectroscopy (μFTIR). Anthropogenic particles were found in 180 of 182 individuals. Finfish contained 0.02–1.08 AP/g of muscle tissue. In pink shrimp (Pandalus jordani), the average AP/g was 10.68 for vessel-retrieved and …

Data were analyzed using descriptive statistics, while the T-test assessed the significance of identified logistics factors. The findings revealed that seventeen logistics factors influence material procurement, with seven factors emerging as the most significant: on-time delivery, transportation challenges, material misdelivery, delivery inaccuracies, order processing, storage capacity limitations, and ineffective information flow. …


Gender Equity And Coffee Agroforestry: The Environmental And Social Impacts Of Commodity Production In Latin America, Suzanna Lloyd Dec 2024

Gender Equity And Coffee Agroforestry: The Environmental And Social Impacts Of Commodity Production In Latin America, Suzanna Lloyd

Student Theses 2015-Present

This paper addresses the environmental and social implications of coffee growth and production in Latin America. Women contribute significantly to the ownership of coffee farms and labor of coffee production; however, there is a lack of resources and financial compensation for their work. Chapter One provides both quantitative and qualitative data on the environmental impacts of coffee plantations compared to agroforestry methods of coffee production in Latin America. This chapter defines basic terms, differentiates coffee species and mode of production, and explains the ecosystem services of biodiverse, tropical farms. Chapter Two highlights the patriarchal nature of Latin American agriculture systems …


Introduction: Failed Futures? (Post)-Colonial Planning And Future-Making In Tanzania, Ulrike Lindner Dec 2024

Introduction: Failed Futures? (Post)-Colonial Planning And Future-Making In Tanzania, Ulrike Lindner

Zamani: A Journal of African Historical Studies

Future-making and planning as social practices are strongly related to the
surrounding society’s political structures and power relations. In this
special issue of ZAMANI, we conceptualize future-making as physical
changes and social practices that shape future conditions by making future
an issue in the present. We analyse how different approaches to the future,
and also surprises and unintended side-effects, have informed the politics
and practices of planning in Tanzania and its various regions.1 When we ask:
“Failed Futures?” we address future in the plural, a term that has diffused
into historical scholarship rather recently and originates from
futurology/future studies, known …


‘Sold Down The River’: Histories Of Production, Trade, And Transport Along The Waterways Of The Kilombero Valley, Tanzania, Jonathan M. Jackson Dec 2024

‘Sold Down The River’: Histories Of Production, Trade, And Transport Along The Waterways Of The Kilombero Valley, Tanzania, Jonathan M. Jackson

Zamani: A Journal of African Historical Studies

This article considers the centrality of waterways in the Kilombero Valley of Tanzania to the region’s histories of development from above, particularly in terms of infrastructure, crop production, trade, and transport. Early colonial investigations hoped Kilombero’s riverine system might prove a navigable link from the coast to the Southern Highlands. The British colonial era instead focused more on utilising riverine networks for internal goods transport. Throughout these colonial visions – simultaneously ambitious and naïve – the prevalent dug- out canoe was considered unsafe, inefficient, and replaceable by modernised methods. But the canoe – a symbol of indigenous knowledge and practice …


Imagining Hydropower: Transnational Narratives And Realities Of The Stiegler’S Gorge Project In Tanzania, 1960s–1980s, Emma Athanasio Minja Dec 2024

Imagining Hydropower: Transnational Narratives And Realities Of The Stiegler’S Gorge Project In Tanzania, 1960s–1980s, Emma Athanasio Minja

Zamani: A Journal of African Historical Studies

Hydropower development in the Global South has attracted several donor programmes for decades. How have such interventions shaped energy imaginations in Tanzania? Adopting a historical perspective and drawing on transnationalism and travelling frameworks, this article examines hydropower aid interventions and the dynamic shifts of specific actors and discourses in bilateral relations. The primary focus is on Norway, a leading actor in planning the Stiegler’s Gorge hydropower project in Tanzania’s Rufiji Basin in the 1970s to mid-1980s. It seeks to understand how, despite substantial aid support, the project failed to kick off in the face of the country’s post-independence drive for …


Nurturing Traditional Midwifery And Medicine: The Entangled Path Of Health Integration In Post-Independence Kilombero, Tanzania, Veronica Kimani Dec 2024

Nurturing Traditional Midwifery And Medicine: The Entangled Path Of Health Integration In Post-Independence Kilombero, Tanzania, Veronica Kimani

Zamani: A Journal of African Historical Studies

This paper focuses on the Tanzanian government’s ambitious endeavour to enhance health, particularly midwifery services following independence. The initial strategy by the government involved promoting Western medicine by establishing healthcare facilities and training medical personnel. However, the strain of a burgeoning population and limited resources soon became evident, prompting the government to recognise the need for the incorporation of traditional medicine, previously overlooked. This integration posed its own set of obstacles, as the focus on herbal remedies overshadowed crucial aspects of conventional midwifery, such as rituals. While research has shown the resolve of the government towards medical integration between different …


Health Infrastructure Planning In Tanzania, 1961–1980s: The Problems Of Future-Making, Frank Edward, Ulrike Lindner Dec 2024

Health Infrastructure Planning In Tanzania, 1961–1980s: The Problems Of Future-Making, Frank Edward, Ulrike Lindner

Zamani: A Journal of African Historical Studies

Between 1961 and 1978, Tanzania invested significantly in the health service provision – from training requisite manpower, provision of health education to building the necessary infrastructure in order to improve health conditions of the population. As existing research indicates, the investment paid off considerably in qualitative terms, for instance, with a gradual increase in life expectancy and a decline in infant mortality. This paper examines the vision of the state of health in Tanzania by using the prism of infrastructure. Its focus is on direct and indirect physical infrastructures, particularly medical buildings and facilities. Through the analysis of archival and …


Front Matter - Zamani 1, No. 1, Editors Note Dec 2024

Front Matter - Zamani 1, No. 1, Editors Note

Zamani: A Journal of African Historical Studies

This is the maiden issue of Zamani: A Journal of African Historical Studies. It charts the beginning of a continental journal that is based in an African higher education institution within Africa. It breaks away from the traditional historical journals in Africa of being national or regional and at best being owned and operated by scholars and institutions from Europe and North America. With this maiden issue, the journal seeks to demonstrate that it is part of the bigger knowledge decolonization movement. It seeks to influence historical writing and research by giving more Africanness in ownership, operations, production and knowledge …


Medical Mission Futures: German Protestant Missionaries And Modern Healthcare In Southern Highlands, Tanzania,1891–1940, Luoneko Kaduma Dec 2024

Medical Mission Futures: German Protestant Missionaries And Modern Healthcare In Southern Highlands, Tanzania,1891–1940, Luoneko Kaduma

Zamani: A Journal of African Historical Studies

The history of colonial missionaries in Tanzania is marked by a complex interplay between evangelical efforts and the provision of Western biomedicine, which functioned as crucial mechanisms for conversion and cultural transformation. Missionaries viewed the improvement of African health as a project aimed at attracting converts and propagating Christianity. However, the available data indicates that, instead of genuinely expressing interest in converting to Christianity, the majority of Africans primarily sought mission medical assistance for medical reasons while maintaining strong connections to their traditional beliefs and healing practices. This paper, drawing from archival documents, ethnographic accounts, and missionary writings, focuses on …


‘Prevention Is Better Than Cure’: Smallpox Vaccination In Postcolonial Tanzania, 1961–1980, Musa Sadock Dec 2024

‘Prevention Is Better Than Cure’: Smallpox Vaccination In Postcolonial Tanzania, 1961–1980, Musa Sadock

Zamani: A Journal of African Historical Studies

This article examines the smallpox vaccination programme in postcolonial Tanzania from the 1960s to the early 1980s as part of the postcolonial future making in preventive medicine. The article departs from extant scholarship on smallpox vaccination in postcolonial Tanzania, which depicts the intervention as a success, while relegating to the background challenges associated with the intervention. The article argues that the smallpox vaccination programme registered challenges and successes that offer lessons for combating of future epidemics. The achievements of the programme were due to the adoption of specific public health policies, namely mass vaccination and public health education as well …


Predicting Movie Production Years Through Facial Recognition Of Actors With Machine Learning, Asraa Muayed Abdalah, Noor Redha Alkazaz Dec 2024

Predicting Movie Production Years Through Facial Recognition Of Actors With Machine Learning, Asraa Muayed Abdalah, Noor Redha Alkazaz

Baghdad Science Journal

This study used machine learning algorithms to identify actors and extract the age of actors from images taken randomly from movies. The use of images taken from Arab movies includes challenges such as non-uniform lighting, different and multiple poses for the actors and multiple elements with the actor or a group of actors. Additionally, the use of make-up, wigs, beards, and wearing different accessories and costumes made it difficult for the system to identify the personality of the same actor. The Arab Actors Dataset-AAD comprises 574 images sourced from various movies, encompassing both black and white as well as color …


Defining The Social Licence Of Large Language Models In Healthcare, Robin L. Pierce, Jack Gallifant, Ashley Cordes, Amelia Fiske, Matilda Dorotic, Mataroria Lyndon, Shrey Jain, Joe Zhang, Judy Gichoya, Leo Anthony Celi Dec 2024

Defining The Social Licence Of Large Language Models In Healthcare, Robin L. Pierce, Jack Gallifant, Ashley Cordes, Amelia Fiske, Matilda Dorotic, Mataroria Lyndon, Shrey Jain, Joe Zhang, Judy Gichoya, Leo Anthony Celi

Seattle Journal of Technology, Environmental, & Innovation Law

As Large Language Models (LLMs) continue to grow and evolve, the ethical, social, and legal challenges they present, especially in terms of data use and sharing, come sharply into focus. Particularly in high-risk domains like healthcare, where the sensitivity of data is pronounced, and the ramifications of data leakages or misuse are profound. These licenses, envisioned to address the complexities introduced by LLMs, still grapple with barriers that hinder their full potential: notably, the absence of authoritative regulatory bodies, ambiguities in defining what constitutes 'sufficient public benefit', issues of data sovereignty, and dilemmas surrounding responsibility and liability. Herein, we delve …

Re-Indigenizing And Collaboratively Tending Urban Greenspaces, Divinity Nnenne Adewale Dec 2024

Re-Indigenizing And Collaboratively Tending Urban Greenspaces, Divinity Nnenne Adewale

University Honors Theses

This work details the active process of land tending with the intention of re-Indigenization in the Pacific Northwest at several Portland sites; The Native American Student Community Center, PSU Oak Savanna, and the Ridgefield National Wildlife Refuge. Land tending is an intuitive process, one rooted in love and respect for life of all forms as well as becoming the perpetual student; land tending is not a skill to be mastered, only practiced. Unlike environmental management, tending cannot be done separate from the earth, in a classroom or otherwise. Connections are what tending is built on top of: the foundation; effort …


Transhistorical Connectivities Around The Indian Ocean: Western Colonialism And Climate Change In Amtav Ghosh's The Nutmeg's Curse, Maria-Sabina Draga Alexandru Dec 2024

Transhistorical Connectivities Around The Indian Ocean: Western Colonialism And Climate Change In Amtav Ghosh's The Nutmeg's Curse, Maria-Sabina Draga Alexandru

Kritika Kultura

This article argues that Amitav Ghosh’s non-fiction book The Nutmeg’s Curse illustrates the ways in which the proto-global entanglement of chaotic colonial forces, which proliferates across space and time, has played an important part in the current climate change. Ghosh imagines the Indian Ocean as a melting pot of rhizomatic energies of imperial aggression and local resistance, but also of new emerging life, with the agency of nature playing a very important part in the latter. I aim to show this in a combined Deleuzian, postcolonial, and ecocritical reading, with elements of chaos theory meant to provide possible interpretations to …


Exploring Environmental Issues In Children's Literature: An Ecocritical Study Of Zhang Wei's Works, Yi Yang Dec 2024

Exploring Environmental Issues In Children's Literature: An Ecocritical Study Of Zhang Wei's Works, Yi Yang

Kritika Kultura

Zhang Wei is one of the most influential authors in contemporary Chinese literature. His earlier works were written for adults, but he has recently contributed to children’s literature as well. While each of his children’s books has its own original storylines, they share a strong interest in environmental issues and contain some obvious themes of ecological consciousness. Peninsular Ha Li Ha Qi, which was influenced by Henry David Thoreau’s Walden, is a kind of pastoral literature. Looking for the Fish King, on the other hand, deals with “toxic discourse,” informing children about the life-destroying evils of modern industrial technology. Last …


Packing Death In Australian Literature, Iris Ralph Dec 2024

Packing Death In Australian Literature, Iris Ralph

Kritika Kultura

In this article, the author identifies critical connections between the transformation of food in the last two hundred thirty years and arguments by animal studies, indigenous studies, ecocriticism, ecofeminism, and environmental history scholars. She does that through a reading of two works of Australian literature: Merlinda Bobis’s cli-fi novel Locust Girl and Evie Wyld’s post-pastoral fiction All the Birds Singing. Bobis’s novel raises questions about the given transformation as it directly relates to the birth of the commercial kangaroo-meat industry, depletion of arable land as a direct consequence of the overuse of it for introduced species of animals reductively called …


Past And Futures Of E. San Juan, Jr., Charlie Samuya Veric Dec 2024

Past And Futures Of E. San Juan, Jr., Charlie Samuya Veric

Kritika Kultura

In this synthetic introductory essay, I consider the places of E. San Juan, Jr. as gleaned from the contributions to this special section: from San Juan’s childhood in Manila and early education at the University of the Philippines at a time when veterans of the 1898 Revolution were still alive and peasant-based insurgency was on the rise; to his implicit contribution to the study of popular culture in the Philippines in the context of the emergence of nationalist struggle in the 1960s; to his turning point as a materialist literary critic who wrote the study on Bulosan which coincided with …

Us Ecological Systems And Climate Adaptation Strategies, Ian Munro

Sustainable Supply Chain Management

This paper is a an introduction and discussion about the various ecosystems of the United States, the different practices of business that hurt them, and how to solve them and create better sustainable resource practices. The ecosystems involve deserts, prairies, and forests which are the main biomes that make up the US. It delves deep in depth of how business affects it and how better sustainability can save it.


Social Learning And Cultural Enrichment For Fish Welfare, Chiawen Chiang, Becca Franks Dec 2024

Social Learning And Cultural Enrichment For Fish Welfare, Chiawen Chiang, Becca Franks

Animal Sentience

This commentary examines how understanding animal culture—shared behaviors and knowledge transmitted through social learning—plays a role in advancing welfare practices for captive fishes. Despite extensive evidence of fishes' complex sociocultural capacities, their psycho-social needs remain underestimated and unmet in zoos and aquaria. We explore what considering fish culture might mean for welfare practices: diverse social learning opportunities, cultural development, and thoughtful group management. More knowledge about wild fishes' lives will help bridge the gap between their full, complex lives and current captive welfare practices.


Discharge-To-Water Level Conversion Using Monthly Duration Curves (Dwl-Mdc): Enhancing The Utility Of The Geoglows Ecmwf Hydrological Model, Darlly Judith Rojas Lesmes Dec 2024

Discharge-To-Water Level Conversion Using Monthly Duration Curves (Dwl-Mdc): Enhancing The Utility Of The Geoglows Ecmwf Hydrological Model, Darlly Judith Rojas Lesmes

Theses and Dissertations

Flood early warning systems are crucial for disaster risk reduction strategies, enabling communities to take timely action against threats. However, the effectiveness of these systems depends on accurate and timely hydrological data, particularly river discharge and water level measurements. Unfortunately, many regions, face significant challenges in obtaining hydrological data, especially discharge data due to outdated rating curves, high equipment costs, and logistical constraints. Water level measurements, by contrast, offer reduced uncertainty and are often more accessible, providing an alternative for hydrological modeling in data-scarce regions. To address these limitations, we developed and validated the Discharge-to-Water Level Conversion Using Monthly Duration …


Modern Agricultural Servitude: The Modern Farm Worker Experience In The Salinas Valley, Jesus E. Tavarez Dec 2024

Modern Agricultural Servitude: The Modern Farm Worker Experience In The Salinas Valley, Jesus E. Tavarez

Chicana and Chicano Studies ETDs

The prevailing narrative in Chicanx studies focuses on the historical labor activism of the United Farm Workers (UFW) in the 1960s and ‘70s. I am particularly interested in examining the contemporary campesino experience in the Salinas Valley by discussing the history behind Mexican cheap labor, low wages, exploitive work conditions with inadequate healthcare, agrochemical exposure, and historical consciousness of farm workers. I will argue that farm workers are in dire need of a migratory reform as an approach to improve the working conditions of farm workers throughout California. This research aims to shed light on how the multi-billion-dollar agribusiness industry …


The Structure And Function Of A Coastal State Aquaculture Plan, C. R. Fong, C. M. Gonzales, M. Rennick, H. J. Lahr, L. D. Gardner, B. S. Halpern, H. E. Froehlich Dec 2024

The Structure And Function Of A Coastal State Aquaculture Plan, C. R. Fong, C. M. Gonzales, M. Rennick, H. J. Lahr, L. D. Gardner, B. S. Halpern, H. E. Froehlich

Faculty Research, Scholarly, and Creative Activity

Aquaculture contributes approximately half of all global aquatic food production and will be critical in addressing future seafood demand, including the United States (U.S.). Many states, territories, and countries are developing and updating aquaculture specific policy in an effort to plan for, and better manage the expansion of aquaculture in their territorial waters. The U.S. has considerable potential to sustainably expand aquaculture production, which has been a focus in both federal and state policy. State aquaculture plans have been used for over 40 years to help plan and coordinate aquaculture development, with a growing emphasis on sustainability. Here, we located …


Documenting Sensation: Reimagining Urban Data For Equity And Sustainability, Nathan R. Johnson, Meredith A. Johnson Dec 2024

Documenting Sensation: Reimagining Urban Data For Equity And Sustainability, Nathan R. Johnson, Meredith A. Johnson

Proceedings from the Document Academy

This paper explores the historical and contemporary practices of documenting urban planning in Tampa Bay, emphasizing the role of sensory experiences in fostering sustainable and equitable development. Using the 1989 Future of Hillsborough Transportation Concepts white paper as a case study, the research critiques the dominance of efficiency-focused documentation in urban policy. This study highlights how such frameworks often neglect cultural and sensory dimensions critical to community well-being. The research calls for a shift towards documenting sensory experiences, drawing on the concept of the sensorium, to bridge the gap between technical data and lived urban experiences. The paper argues that …


Blood On Their Hands: Settler Colonial States In The Arctic, Mer M. Dec 2024

Blood On Their Hands: Settler Colonial States In The Arctic, Mer M.

Tapestries: Interwoven voices of local and global identities

The Arctic is currently the most rapidly warming region in the world. Modern-day media has been transfixed by the image of the poor polar bear, eeking out a difficult living as the sea ice they depend on has been melting. What often remains outside of the frame, however, are the more complex questions about how we got to this point of extreme climate change. Linking the genocidal histories of Indigenous assimilation in the Arctic to the modern-day ecological crises plaguing the region introduces the state as an overlooked climate polluter. While Arctic communities are all on the frontlines of climate …


Weaving Resistance: Indigenous And Mestizé Women In Peru’S Political Uprisings, Isabella Benjamin-Quintana Dec 2024

Weaving Resistance: Indigenous And Mestizé Women In Peru’S Political Uprisings, Isabella Benjamin-Quintana

Tapestries: Interwoven voices of local and global identities

This qualitative research paper investigates how race, gender, and political agency intersect in the lived experiences of Peruvian Indigenous and Mestizé women as they engage in political organizing and protest. This paper focuses on their roles, perspectives, and experiences during the 2022–2023 popular uprisings in Peru, highlighting the unique challenges and contributions of these women in a period of intense social and political upheaval. This paper first uncovers what catalyzed these movements into action, particularly after the impeachment of Peru’s former President, Pedro Castillo. Then this paper will explore race and gender construction in Peru, through pre-colonial, colonial and post-colonial …


Denmark’S Depth Model Version 2.0 – Improved Compilation Of Bathymetric Data Within The Danish Waters, Giuseppe Masetti, Philip Sigaard Granding, Kasper Langdahl, Lasse M. Schwenger, Kristian V. Kristmar Dec 2024

Denmark’S Depth Model Version 2.0 – Improved Compilation Of Bathymetric Data Within The Danish Waters, Giuseppe Masetti, Philip Sigaard Granding, Kasper Langdahl, Lasse M. Schwenger, Kristian V. Kristmar

Center for Coastal and Ocean Mapping

Denmark’s Depth Model version 2.0 (DDM v2.0) is the latest iteration of a Digital Bathymetric Model (DBM) for Danish waters, offering a grid resolution of 50 meters. The compilation integrates hundreds of survey datasets, including both modern and historical sources, as well as satellite-derived and crowdsourced bathymetric data. The model is referenced to Mean Sea Level (MSL) datum and – due to the adopted compilation process – is not designed for safety of navigation. DDM v2.0 is accessible through the Danish Geodata Agency's website and constitutes a significant contribution to the European Marine Observation and Data Network (EMODnet) Bathymetry initiative.


The Fashion Regulation Fight, Eliot L. Force Dec 2024

The Fashion Regulation Fight, Eliot L. Force

Capstones

Fast fashion is a rising global phenomenon with terrible consequences for the environment and laborers across the world. In the US, fashion-specific environmental and labor regulation is practically non-existent at the federal level, but some individual states have begun proposing fashion regulation bills with the aim of curbing the industry’s harms. But in every state where these regulations have been proposed, powerful industry trade groups and companies have been fighting back against those proposed regulations, with much success, through lobbying. As climate change gets worse and the fashion industry’s practices remain unchanged, the need for regulation only becomes greater, but …
