Aim: This paper develops the information for the H. naledi early juvenile life stage, as defined by a combination of deciduous and permanent dentition, and the eruption of the first permanent molar. Subjects and methods: The growing number of young individuals recovered from the Rising Star cave system allows us to gain a better understanding of their variation, or lack thereof, and provides a basis to estimate broad ranges for age at death of …

Human–Environment Interactions At Ta’Ab Nuk Na, A Submerged Maya Salt Works Site In Belize, Cheryl M. Foster, Heather Mckillop, E. Cory Sills

Faculty Publications

Sea-level rise and settlement are investigated at Ta’ab Nuk Na, an ancient Maya salt works in Belize, by examining samples from wooden posts and marine sediment. The samples included Post 145 of Building B and the Nunavut beam, along with marine sediment columns cut from beside both wooden posts. The sediment columns were sampled at 2 cm intervals. Loss-on ignition confirmed the presence of organic material. Identifying the organic content involved removing nonorganic material from the sediment and sorting the organic material under magnification. This procedure established that most of the organic material was red mangrove (Rhizophora mangle). Red mangroves …

Flooded Mangrove Landscapes Hide Ancient Maya Coastal Sites In Belize, Heather I. Mckillop

Faculty Publications

Evidence of ancient Maya exploitation of salt, other marine resources, settlement, and sea trade is hidden in flooded mangrove landscapes on the cays, mainland, and in shallow offshore locations on the south coast of Belize. This article includes a discussion of the coastal economy from the Middle Preclassic through the Postclassic periods (600 B.C.–A.D. 1500). Data from sites discovered and excavated since 1982 in the coastal area of the Port Honduras and Paynes Creek National Park support a model of coastal reliance on marine resources and tree crops. The need for a regular supply of coastal salt to inland cities …

Dpal-Bert: A Faster And Lighter Question Answering Model, Lirong Yin, Lei Wang, Zhuohang Cai, Siyu Lu, Ruiyang Wang, Ahmed Alsanad, Salman A. Alqahtani, Xiaobing Chen, Zhengtong Yin, Xiaolu Li, Wenfeng Zheng

Faculty Publications

Recent advancements in natural language processing have given rise to numerous pre-training language models in question-answering systems. However, with the constant evolution of algorithms, data, and computing power, the increasing size and complexity of these models have led to increased training costs and reduced efficiency. This study aims to minimize the inference time of such models while maintaining computational performance. It also proposes a novel Distillation model for PAL-BERT (DPAL-BERT), specifically, employs knowledge distillation, using the PAL-BERT model as the teacher model to train two student models: DPAL-BERT-Bi and DPAL-BERT-C. This research enhances the dataset through techniques such as masking, …

Convolution-Transformer For Image Feature Extraction, Lirong Yin, Lei Wang, Siyu Lu, Ruiyang Wang, Youshuai Yang, Bo Yang, Shan Liu, Ahmed Alsanad, Salman A. Alqahtani, Zhengtong Yin, Xiaolu Li, Xiaobing Chen, Wenfeng Zheng

Faculty Publications

This study addresses the limitations of Transformer models in image feature extraction, particularly their lack of inductive bias for visual structures. Compared to Convolutional Neural Networks (CNNs), the Transformers are more sensitive to different hyperparameters of optimizers, which leads to a lack of stability and slow convergence. To tackle these challenges, we propose the Convolution-based Efficient Transformer Image Feature Extraction Network (CEFormer) as an enhancement of the Transformer architecture. Our model incorporates E-Attention, depthwise separable convolution, and dilated convolution to introduce crucial inductive biases, such as translation invariance, locality, and scale invariance, into the Transformer framework. Additionally, we implement a …

Afbnet: A Lightweight Adaptive Feature Fusion Module For Super-Resolution Algorithms, Lirong Yin, Lei Wang, Siyu Lu, Ruiyang Wang, Haitao Ren, Ahmed Alsanad, Salman A. Alqahtani, Zhengtong Yin, Xiaolu Li, Wenfeng Zheng

Faculty Publications

At present, super-resolution algorithms are employed to tackle the challenge of low image resolution, but it is difficult to extract differentiated feature details based on various inputs, resulting in poor generalization ability. Given this situation, this study first analyzes the features of some feature extraction modules of the current super-resolution algorithm and then proposes an adaptive feature fusion block (AFB) for feature extraction. This module mainly comprises dynamic convolution, attention mechanism, and pixel-based gating mechanism. Combined with dynamic convolution with scale information, the network can extract more differentiated feature information. The introduction of a channel spatial attention mechanism combined with …

Architects Of War: The Economic And Industrial Strategies Of The Third Reich And United States Under Albert Speer And William Knudsen, Spencer David Taylor

CMC Senior Theses

This thesis presents a chronological narrative that delves into the economic and industrial underpinnings of the Second World War, focusing on the contrasting war machines of Germany and the United States. By examining the strategic decisions and outcomes shaped by two central figures, Albert Speer of Germany and William S. Knudsen of the United States, this study highlights how their approaches to war production profoundly influenced the overall trajectory and outcome of the war. Knudsen’s embodiment of the American industrial spirit and Speer’s manipulation of Germany's constrained resources illustrate the crucial roles that economic strategies played alongside military operations. The …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Museum biological collections store species data that can be utilized in research on biodiversity, environmental change, invasive species, public health, and disease. The University of Arkansas Arthropod Museum, which began in 1905, houses over 750,000 specimens and has not yet been digitized. Making data publicly accessible via the internet makes the data available to the entire scientific community. The goal of this project was to create a digital resource to allow greater access to the University of Arkansas Arthropod Museum holdings. To do so, data from Bombus (bumble bee) and Xylocopa (carpenter bee) specimens were entered into a database in …

The Intersection Of Asset Management And Geographic Information Systems For University Facilities Maintenance, Andrew Westerlund Beland

Masters in GIS Practicum Reports

This project describes a proof of concept for developing a digital asset management system dashboard for water backflow assemblies at Portland State University (PSU) using a modified ESRI ArcGIS Online backflow solution. Asset management is crucial for optimizing the lifecycle of tangible assets, which ensures cost-effective operational efficiency and regulatory compliance. PSU manages over 250 backflow assemblies spread across the 50-acre campus and has traditionally relied on manual processes, which can lead to inefficiencies and potential transcription errors.

The system links spatial data with asset attributes for backflow devices, enabling field staff to update inspection results directly from mobile devices. …

Cartographies Of Black Diaspora And Foster Care Diaspora: Arguments Toward Abolition In The Aftermath Of Partus Sequitur Ventrem, Alicia Boyce

CGU Theses & Dissertations

In this dissertation I argue that global foster care and adoption systems should be abolished because they are trauma inducing and grief producing state apparatuses that cyclically act to destabilize Black and “Other” subaltern populations from one generation to the next. Global foster care and adoption systems have become as common sensical as enslavement and chattel slavery all were as these systems are considered widely socially acceptable, common modes of domination and methods for controlling Black and “Other” populations. I coin a diaspora of community and cultural destabilization called the foster care diaspora (FCD), a theory and framing device that …

Earliest Ancient Maya Salt Production In Southern Belize: Excavations At Jay-Yi Nah, Heather Mckillop, Cory Sills

Geography Faculty Publications and Presentations

Salt works along the Yucatan coasts of Mexico and Belize provide a record of salt production for inland trade during the height of Late Classic Maya civilisation (AD 550–800). At the Paynes Creek Salt Works in Belize, production focused on the creation of salt cakes by boiling brine in pots supported over fires in dedicated salt kitchens. Underwater excavations at the Early Classic (AD 250–550) site of Jay-yi Nah now indicate there was a longer and evolving tradition of salt making in the area, one that initially employed large, incurved bowls to meet local or down-the-line trade needs before inland …

Crisis, Genre, And The Informatic Infrastructure Of The Critical Path Aids Project In Philadelphia's Early Epidemic, Sid Feinberg

Theses and Dissertations--Geography

The Critical Path AIDS Project was a grassroots information network that distributed AIDS-related information related to biomedicine, social services, and politics. I explore the ways the project made sense of the shattering social service and care landscapes they emerged within and responded to. I situate Critical Path’s work within Philadelphia’s splintering care infrastructures and the experience of crisis Lauren Berlant argues structures perception of neoliberal life. I focus on the ways that Critical Path’s articulation of crisis and spatial re-orientation pull on the modernist design work of Buckminster Fuller. Fuller’s design work formed a framework through which the project constructed …

Beauty And The Anthropocene: On The Emancipatory Potential Of Experiences Of Beautiful Places In The Natural World, Matthew John

Theses and Dissertations--Geography

This dissertation investigates the proposition that beauty—specifically, experiences of beautiful places in the natural world—can contribute to the emancipation of modern persons (and thereby developed societies) from instrumental rationality, which is theorized as a major driver of contemporary socioecological crises of the Anthropocene. Buber’s concept of the I–Thou relation provides a framework for conceptualizing ideal non-instrumental relations. The project’s methodology, rooted in post-phenomenology, consisted of semi-structured remote interviews and four follow-up focus groups with 35 then current and recently former residents of Juneau, Alaska. Taken together, data confirm that experiences of beautiful places in the natural world can and do …

A Geography Of Transgender Belonging In Louisville, Kentucky, Lj Mcallister

Theses and Dissertations--Geography

Louisville, Kentucky is home to a surprisingly robust – and complex – transgender community. This study uses qualitative data from interviews, collaborative maps, and archival research to analyze a geography of belonging for transgender residents in the city. It discusses how the twelve participants negotiate their relationships with the conservative, “red” state of Kentucky, as well as the geographical decision-making they use to navigate Louisville’s many neighborhoods. Ultimately, this thesis draws attention to the ways in which prejudice shapes the landscape of belonging for transgender life in Derby City.

The Effect Of Water Scarcity On Gender Dynamics In Egypt, Zahwa Kortam

The Undergraduate Research Journal

This article investigates the complex relationship between Egypt's agriculture, water scarcity, and gender dynamics. It highlights the challenges facing the agricultural sector due to water shortages in a country highly dependent on the Nile River for food security and agricultural development. Women, who have been traditionally integral to agriculture, have to deal with multiple challenges posed by water scarcity. For men, their roles are changing, and with that, the power dynamics and social norms. This article attempts to reveal opportunities for gender equality and sustainable use of water resources through the examination differences in experiences between men and women in …

Thirty Years Of ‘Emergency’ Food Aid In The Us And Canada: Findings From Comparative Research To Inform Uk Efforts To Tackle Food Poverty And The Need For Foodbanks, Charlotte Spring

Geography and Environmental Studies Faculty Publications

Research observed how food providers in the United States and Canada have made changes during the decades of neoliberal policymaking that have seen foodbanking expand across North America and beyond. These changes, in part, reflect responses to critiques of foodbanking as an inadequate solution to food insecurity. Food charities have variously attempted to improve provision through healthier procurement, choice-based distribution models, diversified programming, and advocacy for policy solutions. Better foodbanking, however, does not negate the influence of corporate donors on food charities’ capacity to foster hunger-preventative change, such as the employment practices of those same donors. Meanwhile, grassroots organisers …

Stories, People, And Industrial Heritage Landscapes: Integrating Spatial Narratives And Deep Mapping For Use In Public Heritage, James A. Juip

Dissertations, Master's Theses and Master's Reports

Understanding the complexity of the industrial heritage landscape and working towards its holistic representation are long standing challenges for heritage practitioners and scholars alike. This dissertation focuses on addressing a gap in industrial heritage scholarship by addressing the question; can the integration of spatial narratives and deep mapping theory and practice improve upon the practice of public discourse in industrial heritage? Community heritage narratives are an important intangible aspect of the industrial heritage landscape that forms a discursive relationship with authorized heritage sources. Influencing this discourse can alter contemporary power relations that intertwine modern issues with perceptions of the past. …

Recovering The Nium Trail: A Journey Through Collaboration And Multidisciplinary Mapping, Crystal West

Graduate Student Theses, Dissertations, & Professional Papers

This study explores and maps an ancient, historic, and contemporary travel corridor that follows the San Joaquin River in the Central Sierra Nevada of California. It is called the Nium or People’s Trail by the North Fork Mono Tribe, the French Trail in historic archives, and the Mammoth Trail on contemporary US Forest Service maps. When I agreed to the request by Chairman Ron Goode of the North Fork Mono Tribe to map the Nium Trail, I was saying yes to a different, more broad and inclusive approach than I had previously taken as an archaeologist documenting archaeological sites and …

Climate Change And Critical Agrarian Studies, Ian Scoones, Saturnino M. Borras Jr., Amita Baviskar, Marc Edelman, Nancy Peluso, Wendy Wolford

Publications and Research

Climate change is perhaps the greatest threat to humanity today and plays out as a cruel engine of myriad forms of injustice, violence and destruction. The effects of climate change from human-made emissions of greenhouse gases are devastating and accelerating; yet are uncertain and uneven both in terms of geography and socio-economic impacts. Emerging from the dynamics of capitalism since the industrial revolution — as well as industrialisation under state-led socialism — the consequences of climate change are especially profound for the countryside and its inhabitants. The book interrogates the narratives and strategies that frame climate change and examines the …

Sustainability Starts Small: Initiatives From Cuba To The Bitterroot Valley, Kathryn Marie Simecek

Graduate Student Theses, Dissertations, & Professional Papers

Sustainability and sustainable business practices look different across every resource and industry.

From recreational scuba diving to grassroots recycling efforts, sustainability is driven by local communities with a vested interest in protecting their environments long-term. Access to these sustainability efforts and awareness about their existence are barriers that require intentional participation in sustainable resource use from relevant parties. In this professional paper, sustainability efforts will be examined across three domains. Food-grade glass is one of the easiest and most efficient items to recycle, but relatively little of it is recycled. Discarded glass can take various paths, from community-led recycling events …

Quantifying Structural Vegetation Change On Arctic Tundra: A Multi-Decadal Study Integrating Remotely Sensed Imagery And Traditional Field Measurements, Anna M. Moser

Graduate Student Theses, Dissertations, & Professional Papers

Arctic regions have experienced an amplified rate of climate warming in recent decades, contributing to well-documented increases in tundra vegetation productivity. Satellite remote sensing has historically played a crucial role in detecting and quantifying trends at regional and biome scales; however, coarse resolution imagery has proven insufficient for capturing fine-scale variability in vegetation response. Considering the spatial heterogeneity of tundra vegetation, high resolution, plot-scale remote sensing observations are necessary. This study couples traditional field measurements with high-resolution unmanned aerial vehicle (UAV) imagery and plane-based aerial photos to quantify changes in vegetation on the North Slope of Alaska over a 28-year …

Net Zero And Settler Futurity, Jesse Goldstein

Sociology Publications

Net Zero ideology promises that current and ongoing emissions can be partially offset by ‘negative emissions’ strategies such as carbon capture and sequestration, allowing carbon intensive firms to narrate themselves as agents that are solving – not causing – the climate crisis. This represents a shift in liberal and corporate environmentalism away from both denial and delay, towards a new strategy acknowledging the need to end fossil fuel use while urgently deferring transformations to a future made possible by not-yet developed technological innovations. This paper argues that a through-line of settler futurity provides affective infrastructure potent enough to transect opposing …

Fire-Vegetation-Climate Interactions: An 8,000- Year Long Paleoecological Reconstruction From Round Lake, Idaho (Usa), Audrey Scott

All Master's Theses

The Idaho Transportation Department recently contracted archeologists from Eastern Washington University (EWU) to assess potential impacts to cultural resources near McArthur Lake in Bonner County, Idaho, as the result of rerouting U.S. Route 95. The goal of this research is to aid EWU archeologists in their interpretation of the artifacts recovered from the McArthur Lake site by providing them with a local paleoecological reconstruction. Lake sediment-based paleoecological reconstructions provide detailed information on fire history and vegetation change through time and indicate how landscapes responded to past climate variability and human activities. In summer 2022, a sediment core was extracted from …

Foodways: An Ethnographic Analysis Of Cwu International Students’ Perception Of The Role Of Culturally Relevant Food In Their Sense Of Belonging, Joy Ihuka

All Master's Theses

International students face unique challenges adjusting to new academic environments, including developing a sense of homesickness and lack of belonging. Studies have shown that consuming culturally relevant food helps international students relieve homesickness, fostering a sense of belonging. Curiously, nonetheless, literature on student belonging rarely focuses on food. Within this gap, this thesis explores the significance of culturally relevant food in fostering a sense of belonging among international students at Central Washington University. Using ethnographic interviews, this research examines how culturally relevant food (including how food is prepared) or lack thereof may influence international students’ perceptions of belonging. This study …

Mind, Body, And Farmland: The Agricultural Revolution Of Regenerative Agriculture And The Social Construction Of Sustainability., Amanda C. Pennett

Honors Theses

An agricultural revolution has begun to take place in light of the growing awareness of environmental issues that impact crop production on farms. In the beginning of the fall of 2022, I began to study the culture of regenerative agriculture in rural Pennsylvania using anthropological methods, including participant-observation and semi-structured interviews, working alongside local farmers. I was also interested in uncovering the flaws in our current industrial agricultural system and how farming could be reimagined to benefit farmers’ mental health, soils, and ecosystems while privileging the voices of those farmers committed to regenerative farming. The ongoing evolution of regenerative farming …

Late Holocene Fire History Reconstruction Of Beaver Lake In The Northwest Lowlands Of The Olympic Peninsula, Grace Mckenney

All Master's Theses

Fire is an essential component of the landscapes and forests of the Pacific Northwest, including the temperate rainforests of the Olympic Peninsula. Previous fire history reconstructions from the peninsula show that fire return intervals varied throughout the postglacial period, primarily in response to climatic changes and corresponding shifts in vegetation. However, much less is known about the fire history of the low-elevation forests of the Olympic Peninsula and the role of cultural fire regimes in these environments. The purpose of this study was to reconstruct the paleoenvironmental history of a low-elevation study site, Beaver Lake, located in the northwestern part …
