Determining The Quality And Quantity Of California Sitka Spruce (Picea Sitchensis) On Private Commercial Timberland For Use In Domestic Acoustic Steel-String Guitars, Ryan Eugene Cooper

Undergraduate Scholarship

Development of additional revenue streams for timber products with relatively low profitability is an important step in securing future economic success for the forestry sector in Humboldt county. Utilization of California Sitka spruce (Picea sitchensis) for use in domestic acoustic steel-string guitar manufacturing may provide exactly that. Determining the quality and quantity of California Sitka spruce is the logical first step in achieving this.

Quality was determined from tree core samples gathered at sites on Green Diamond Resource Company’s (GDRco) California timberlands and the Arcata Community Forest (ACF) with high basal area of Sitka spruce. Rings Per Inch …

Baduwa’T Estuary Riparian Restoration & Revegetation Plan, Brandon Patino, Blake Kennedy, Xitlalli Rodriguez

Undergraduate Scholarship

The Baduwa’t estuary Restoration Project in McKinleyville, California is a place of interest to community members for a variety of reasons – ecological, recreational, and tribal among some of them. The estuary connects the Mad River Watershed to the Pacific Ocean. The project opened four acres of habitat to juvenile salmon and steelhead populations that utilize the watershed while migrating to the ocean. Complications regarding the size and success of plant species and riparian zone expansion remained. Using a list of 9 targeted native plants, we created a botanical literature review focusing on native plants to guide future efforts to …

Connecting Conservation: Modeling And Socializing Climate Connectivity For Land Conservation, Melissa M. Clark

Doctoral Dissertations

As the climate changes, species must either adapt, relocate, or face extinction. This pressing reality underscores the importance of promoting climate connectivity, which ensures that habitats and landscapes remain interconnected, allowing species to move and adapt as climate conditions shift. Given the challenges posed by ongoing climate change, it is crucial that land conservation decisions incorporate climate connectivity. Conservation goals should be informed by the latest connectivity models and be practical for implementation by on-the-ground practitioners. This dissertation aims to bridge the gap between these two critical needs, which are not always well-integrated in conservation work. Modeling connectivity in a …

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 …

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 …

“To Try The Difference”: Encountering A Different Self In Henry Neville’S Isle Of Pines, Andrew Fleck

Literatures and Cultural Studies Faculty Publications

It is critical that the imagined space of Henry Neville’s Restoration-era novella, The Isle of Pines, is an island, a space cut off from the mainland where history and culture can unfold in different ways. The island, encountered unintentionally by “civilized” Europeans during a Dutch trading voyage across the Indian Ocean, has a previously unknown population. Rather than a new, long-established nation of islanders, however, the population are the descendants of five castaways from an English shipwreck. Viewed through the lens of the unfamiliar, these islanders adhere to tropes associated with discovery narratives; simultaneously, the islanders carry with them …

Practicing Vulnerability: A Black Queer Dance That Is Never-Ending Due To The Faults Of Our American Society, Paris Ngai Gray

Dance (MFA) Theses

The performative nature of concert dance requires a profound awareness and understanding of the body and the mind. Formal dance training situates an environment where the investigation of the body is crucial, often leaving the responsibility of internal inquiry to the dancer. In my experience as a Black, Queer, and Trans/Non-Binary person assigned male at birth, this investigation has been incredibly difficult. This research explores not only the sub-cultural context that influenced my resistance to emotional maturity but also the places that shaped my connection to vulnerability and how I’ve been able to access it. The performance of Black hyper-masculinity …

Landscapes Of Play: An Exploration And Illumination Of Children’S Unsupervised Play Close To Home And A Researcher’S Journey To Becoming Posthuman., Mandy Andrews

School of Law, Humanities and Social Sciences Theses

Title: Landscapes of Play: An exploration and illumination of children’s unsupervised play close to home and a researcher’s journey to becoming posthuman. Author: Mandy Jo Andrews This thesis explores children’s play experiences and engagements out of doors close to home. Adopting a Deleuzian informed posthumanism the researcher’s journey towards immanence prompts re-thinking about play, childhood-nature entanglements, and play-space-place-player generation. Children’s unsupervised play outside of organised settings such as school or adventure playgrounds is less researched than that of organised settings. This thesis puts to work Deleuze’s process philosophy and Barad’s agential realism, together with Haraway’s biology informed multispecies manifesto, Bennett’s …

Investigating Inland Waterway Transport Through A Sustainable Development Perspective: A Case Study Of Magdalena River (Colombia), Natalia Calderón-Rivera

World Maritime University Ph.D. Dissertations

The development of transport systems significantly influences economies, growth, and welfare of populations. However, these systems can have negative consequences, such as water and air pollution, traffic congestion, noise, and biodiversity loss. To address these challenges, it is essential to implement strategies that mitigate negative effects while improving the environmental, social, and economic conditions of the population. In this regard, inland water transport (IWT) is globally recognized as a more sustainable transport alternative due to its high cargo load capacities and comparatively lower environmental and social impacts. In Colombia, the Magdalena River – the country’s most important river basin – …

The Greenspace Gap: Environmental Racism And Park Disparities Along The Delmar Divide, Amelie Maltz

Dean James E. McLeod Freshman Writing Prize

Access to greenspace is crucial for both physical and mental health, yet communities of color and low-income neighborhoods throughout the United States are deprived of the benefits that nature provides, a phenomenon known as the “nature gap.” This paper investigates differences in greenspace quality on each side of St. Louis’ “Delmar Divide,” a street that splits the city into the predominantly Black, low-income ‘North City’ and the predominantly white, high-income ‘South City.’ Legacies of historical segregation policies along Delmar Boulevard and throughout the rest of the city have resulted in significant disparities in park quality that contribute to health inequalities …

A New Measure Of Surviving Children That Sheds Light On Long-Term Trends In Fertility, Anup Malani, Ari Jacob

Public Law and Legal Theory Working Papers

The consequences of fertility decline flow primarily from reduction in the number of surviving children, i.e., both births and survival, not simply from reductions in births. Therefore, neoclassical economic theories that attempt to explain fertility decline (e.g., quantity-quality models) hinge on preferences for surviving children, not births per se. This paper provides a new measure of surviving children. Effective fertility rate (EFR) is the product of the current fertility rate and the projected probability that a child survives until some age A. This age A could be between 15-49 for a measure (EFRR) that tracks reproductive potential, or 15-65 for …

Administrative Enslavement, Adam Davidson

Public Law and Legal Theory Working Papers

There are currently over a million people enslaved in the United States. Under threat of horrendous punishment, they cook, clean, and even fight fires. They do this not in the shadow of the law but with the express blessing of the Thirteenth Amendment’s Except Clause, which permits enslavement and involuntary servitude as punishment for a crime.

Despite discussions of this exception in law reviews, news reports, and Netflix documentaries, few commentators have recognized that this enslavement happens silently. No prosecutor, judge, or defense attorney tells convicted people that they will be enslaved as punishment for their crime. It is only …

Politicians The Founders Warned You About, Neil Fulton

UC Law Constitutional Quarterly

Many articles have explored the Founders’ intentions regarding the constitutional text. Much less attention has focused on the Founders’ ideas regarding the traits needed of the leaders in a constitutional republic. The Constitution focuses on governing structures, many of which relate to the electoral process. The Constitution does not spell out the ideal traits of the leaders elected pursuant to those processes. Nonetheless, the Founders possessed clear views about the virtues and qualifications that ideal political leaders required. Indeed, the Founders issued warnings about certain archetypal political figures who, because of their flagrant disregard of the ideal virtues and qualifications, …
