Enlightened Agricultural Improvement In Eighteenth-Century Scotland, Amanda M. Widney

All Master's Theses

Eighteenth-century Scotland is marked by the impact of new ideas from the Scottish Enlightenment that influenced agricultural revolution. Practices that had been used for over hundreds of years with little change, went through a dramatic agricultural reimagining during this time period. Scottish Enlightenment “improvers,” like Henry Home, Lord Kames, demonstrate this push towards “progress.” In particular, Lord Kames represents a conundrum. He, like many other Scots, believed in the authenticity of Ossian’s translated poems by James Macpherson. This patriotic devotion to Scottish culture influenced the way that Kames went about “improving” his own lands and who he chose to work …

Experimentally Linking Head Kinematics To Brain Deformation, Imouline Algharbi

Theses

Traumatic brain injury (TBI) research is used to study the effects of brain injuries and the rehabilitations for them. TBI contributes to major cause of disability and deaths quantifying up to 30% of all the head injuries. To mimic real world impact to understand the mechanism of injury head-surrogate models are used. This thesis describes a method to record head kinematics from acceleration and angular rate sensors of head-brain surrogate model for blast and blunt injury. This methodology is validated through experimental testing. To get a better insight of the head kinematics experienced by a real skull a drop tower …

Imagined Affordances Of Instagram And The Fantastical Authenticity Of Female Gulf-Arab Social Media Influencers, Zoe Hurley

All Works

© The Author(s) 2019. This study explores the image sharing site Instagram to reveal how affordances, or uses of the platform, occur within a nexus of technological architecture, sociocultural contexts, and globalized commercial practices. It suggests social actors draw upon Instagram’s affordances at material, conceptual, and imaginary levels while using social media. This triadic model for theorizing affordances of Instagram responds to the need for mapping ontologies and typologies of social media within increasingly visual, intercultural, and non-Western contexts. The lenses of critical multimodality and a participant-centered method consider how female Gulf-Arab social media influencers operate through an interplay of …

All Works

© 2019 Shah, Liu, Al Kury, Zeb, Abbas, Li, Yang, Liu, Jiang and Li. Stroke is the significant cause of human mortality and sufferings depending upon race and demographic location. Melatonin is a potent antioxidant that exerts protective effects in differential experimental stroke models. Several mechanisms have been previously suggested for the neuroprotective effects of melatonin in ischemic brain injury. The aim of this study is to investigate whether melatonin treatment affects the glutamate N-methyl-D-aspartate (NMDA) and alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor signaling in cerebral cortex and striatum 24 h after permanent middle cerebral artery occlusion (MCAO). Melatonin (5 mg/kg) …

Childhood And Trauma: The Effects Of Adverse Childhood Experiences On The Brain, Behavior, And Learning In The Elementary School Classroom, Aeryn Aguilar

Cal Poly Humboldt theses and projects

A variety of studies have been conducted on how trauma, caused by emotional, physical, or verbal abuse, impact children’s lives. Many of the studies which involved observations and assessments were done with the preexisting knowledge that these children had been through a traumatic experience. Instead of looking at behavior of known cases, this study’s goal is to find out whether or not children’s observable behaviors can predict cases of trauma. For example, is acting out or defiance a key sign of trauma or is it part of the typical development for the elementary school-age group? This thesis takes into account …

Overwinter Survival And Movement Of Juvenile Coho Salmon (Oncorhynchus Kisutch) In Relation To Large Woody Debris And Low-Velocity Habitat In Northern California Streams, John D. Deibner-Hanson

Cal Poly Humboldt theses and projects

Some studies suggest that Coho Salmon populations are limited by overwinter survival as a result of insufficient winter habitat. While many small-scale projects aim to define reach and basin-level habitat requirements for Coho Salmon, large-scale studies that assess multiple independent populations remain few. For my research, I quantified large woody debris (LWD) by volume and low-velocity rearing habitat (LVH) as percent area in three coastal watersheds of similar size in northern California to untangle the relationships between Coho Salmon overwinter survival, emigration timing and specific winter habitats. I used mark-recapture techniques with PIT tags to formulate Cormack-Jolly-Seber models for each …

Relationship Between Habitat And Barn Owl Prey Delivery Rate And Composition In A Napa Valley Vineyard Agroecosystem, Dane A. R. St. George

Cal Poly Humboldt theses and projects

The provision of habitat for natural enemies of agricultural pests is common in integrated pest management approaches globally but has rarely been examined for vertebrate predators controlling vertebrate pests. To mitigate the economic and environmental costs of treating for rodent pests, winegrape producers in Napa Valley, California, have installed nest boxes to attract barn owls (Tyto alba) to their properties, but their effectiveness to control rodent pests in vineyards has not been thoroughly tested. A rigorous estimate of the number of rodents barn owls remove from the landscape is a necessary first step, and this study aimed to …

"Fenced-In Place": White Settler Colonialism As Opposition To Increased Tribal Management Of The National Bison Range, Brittany Lee Palmer

Graduate Student Theses, Dissertations, & Professional Papers

Since the Tribal Self Governance Act was passed in 1994, the Confederated Salish and Kootenai Tribes (CSKT) in western Montana have sought increased management responsibilities at the National Bison Range, which is fully encompassed by the Flathead Indian Reservation. Though the U.S. Fish and Wildlife Service has managed the Bison Range since it was established in 1908, the Tribes assert that they were the original stewards of bison in the area, and have requested both the reinstatement of the National Bison Range to Tribal trust ownership and increased management responsibilities through negotiated Annual Funding Agreements with the Department of Interior. …

Why The Weird Wings? Investigating The Morphology, Function, And Evolution Of Unusual Feathers In Pigeons And Doves (Columbidae), Robert Lawrence Niese

Graduate Student Theses, Dissertations, & Professional Papers

The feathers of the wing that power flight in birds (the remiges) are morphologically constrained by the demands of aerial locomotion, but peculiar morphologies exist in many taxa in spite of these constraints. In the family Columbidae (pigeons and doves) in particular, we found that atypical remex morphologies have evolved dozens of times and occur in over a third of all species in the family. In members of the genus Columbina, we tested the sound-producing abilities of modified P7 feathers and determined that they are sonations that serve a signalling function during flight. In 56 species we identified a highly-attenuated …

Harvesting Forest Biomass In The Us Southern Rocky Mountains, Lucas Patrick Townsend

Graduate Student Theses, Dissertations, & Professional Papers

Ponderosa pine (Pinus ponderosa) and other mixed conifer forests of the United States southern Rocky Mountains (SRM) evolved under a low-severity, high-frequency fire regime. With the arrival of Euro-American colonists, fire was excluded from most forests, causing stands to grow dense and become prone to uncharacteristic high-severity crown fires. To combat wildfire threat, restoration treatments are frequently used to restore historic stand structure and function, effectively reducing high-severity fire risk. However, these treatments may be costly and little information is available regarding the forest operations used in the SRM. In this thesis, five forest operations were studied in 2017 to …

Eu-U.S. International Education Connections: U.S. Opportunities To Participate In Erasmus Programs And The Case For A Renewed Commitment To Transatlantic International Education Collaboration, Peter N. Baker

Graduate Student Theses, Dissertations, & Professional Papers

Abstract The European Union’s suite of Erasmus programs are an ambitious effort to facilitate educational mobility and research across the EU’s 28 member countries and with partners around the world. It is one of the primary means to achieve a sense of European identity among the citizens across the Union, and governmental and educational organizations in the U.S. are keen to learn more about how they can also engage with it. The Departments of State and Education, because of their respective work in international education, are particularly well-positioned to lead that effort. Erasmus is ambitious in its social objectives and …

Community-Centered Sustainable Conservation And Ecotourism Planning In The Bossou Forest Reserve, Guinea, West Africa, Destina Samani

Graduate Student Theses, Dissertations, & Professional Papers

Ecotourism management has evolved over the years towards responsible conservation of the natural environment, sustaining the well-being of local people, enriching personal experiences and increasing environmental awareness. The development of a forest reserve is characteristic of the management–visitor–host community interface and the attendant competing interests in the face of new challenges, ideas and theories. In particular, host community participation in the conservation of the forest space tends to breakdown under weak ecotourism management, partly evident by the imbalanced exploitation of ecosystem services resulting in wildlife and society’s inability to cope effectively with the changes (Walker et al., 2016).

Mechanisms Driving Territorial And Social Behavior In A Cooperative Carnivore, Sarah Nelson Sells

Graduate Student Theses, Dissertations, & Professional Papers

Territoriality is a fundamental and conspicuous behavior of numerous species, including many carnivores. Although relatively uncommon, carnivore sociality is likewise a conspicuous behavior where it occurs. Territorial and social behavior are of theoretical, empirical, and conservation interest because these behaviors can strongly shape demographic processes. Natural selection has likely shaped animals to make decisions that maximize benefits and minimize costs, but the mechanisms driving territory selection and social decisions remain uncertain. Our goals were to increase understanding of these mechanisms. We furthermore sought to develop reliable methods to predict outcomes of territorial and social behaviors, absent costly monitoring efforts. Gray …

Genomic Inference Of Inbreeding In Alexander Archipelago Wolves (Canis Lupus Ligoni) On Prince Of Wales Island, Southeast Alaska, Katherine Emily Zarn

Graduate Student Theses, Dissertations, & Professional Papers

Habitat loss and climate change are increasingly resulting in reduction and fragmentation of wildlife populations. Populations that have experienced fragmentation and decreases in abundance are at heightened risk of inbreeding due to reduced opportunities to mate with unrelated conspecifics. Prolonged or extensive inbreeding can result in inbreeding depression via the exposure of deleterious alleles in long runs of homozygosity. Alexander Archipelago wolves (Canis lupus ligoni) on Prince of Wales Island (POW) in Southeast Alaska are a small, isolated population of conservation concern that have experienced habitat loss and high harvest rates, and present an ideal system in which …

An Investigation Of Historic Euro-American Inscriptions At Madison Buffalo Jump, Jay Thomas Vest

Graduate Student Theses, Dissertations, & Professional Papers

This thesis explores the cultural significance and interpretive potential of historic inscriptions left behind by primarily Euro-Americans at Madison Buffalo Jump; a Native American bison jump situated in the Madison Valley of southwestern Montana. The inscriptions are analyzed through the lens of Cultural Landscape Theory and their typology, distribution, and content are examined in detail. By looking at these inscriptions in this manner, opportunities for ongoing research are highlighted, the future potential of these types of inscriptions to contribute to a new interpretive is examined, and the challenges of appropriate conservation strategies is considered. This thesis presents the argument that …

Thinking Outside Of The Box Ii: Disrupting The Cognitive Map., Matthew G. Buckley, Alastair D. Smith, Mark Haselgrove

School of Psychology

A number of influential spatial learning theories posit that organisms encode a viewpoint independent (i.e. allocentric) representation of the global boundary shape of their environment in order to support spatial reorientation and place learning. In contrast to the trial and error learning mechanisms that support domain-general processes, a representation of the global-shape of the environment is thought to be encoded automatically as part of a cognitive map, and without interference from other spatial cues. To date, however, this core theoretical assumption has not been appropriately examined. This is because previous attempts to address this question have failed to employ tasks …

Two- And Three-Year-Olds Consider Ownership When Selecting And Allocating Resources, M Petrowski, Patricia Kanngiesser, Ori Friedman

School of Psychology

In three experiments, we investigated whether 2- and 3-year-olds (N = 240) consider ownership when taking resources for themselves and allocating resources to another agent. When selecting resources for themselves, children generally avoided taking resources that belonged to another agent and instead favored their own resources (Experiments 1 and 2). However, they did not avoid taking the agent’s resources when the only other resources available were described as not belonging to the agent (Experiment 3). Children also selected fewer of the agent’s resources when taking for themselves than when giving to the agent (Experiments 2 and 3). In giving to …
