Chipping Through Time: The Evolution Of Lithic Spatial Organization At The Bridge River Pithouse Village, British Columbia, Ethan P. Ryan

Graduate Student Theses, Dissertations, & Professional Papers

Archaeological investigations at Housepit 54 within the Bridge River site have, to date, exposed 15 discreet floors primarily dating to ca. 1500-1000 cal. B.P. In this thesis, the spatial distributions of lithic artifacts from every floor are examined. Questions will be addressed specifically towards formation processes and the potential relationships between the patterning of lithic distributions as they relate to hearth-centered activity areas or domestic areas and fluctuations in estimated population. In addition, this thesis explores spatial organization as a cultural trait or concept that can be transmitted through time. Using the same methodological and theoretical approach for each floor, …

Healing Self And Community: Living Pluralism In The Anishinaabe Paradigm, Andrea A. Fitzpatrick

Graduate Student Theses, Dissertations, & Professional Papers

Abstract: Healing Self and Community: Living Pluralism in The Anishinaabe

This thesis is a study of pluralism through Anishinaabe writers Winona LaDuke, Basil Johnston, Lynn Anderson, and others, focusing on their perceptions and pedagogies and how those perceptions inform pluralistic living. Anishinaabe methodology tends to be innately interconnected, and pluralistic. As such, it can enlighten, heal self-identity structures, and perceptions of the biosphere. I will contextualize how it is necessary to investigate the stories we learn and those we tell, how it is vital to understand where they come from. Included is analysis of how pluralism shows up in mine …

Predictive Spatial Modeling Of Wildfire Occurrence And Poaching Events Related To Siberian Tiger Conservation In Southwest Primorye, Russian Far East, Conor N. Phelan

Graduate Student Theses, Dissertations, & Professional Papers

Siberian tiger (Panthera tigris altaica) populations worldwide have been drastically reduced in number over the past several decades. The Primorye region of the Russian Far East remains one of the final strongholds for the estimated 400 Siberian tigers remaining in the wild. As a flagship species, Siberian tigers play a crucial socio-economic role in helping agencies and non-profits to motivate, fund, and implement broader conservation efforts. Even while defended by organizations such as the Wildlife Conservation Society (WCS), Siberian tigers in Primorye face an onslaught of threats to their continued existence. Profound land use changes due to the …

Hunting Habitat Use And Selection Patterns Of Barn Owl (Tyto Alba) In The Urban-Agricultural Setting Of A Prominent Wine Grape Growing Region Of California, Xeronimo A. Castaneda

Cal Poly Humboldt theses and projects

Large scale conversion of uncultivated land to agriculture threatens wildlife and can diminish ecosystem services provided by nature. Understanding how wildlife provision ecosystem services may incentivize wildlife conservation in agricultural landscapes. Attracting barn owls (Tyto alba) to nest on farms for pest management has been documented worldwide, but has not been thoroughly evaluated in vineyard agroecosystems. Napa Valley, California is a renowned winegrape growing region, and viticulturists encourage barn owl occupancy to help minimize plant damage from pocket gophers (Thomomys bottae) and voles (Microtus spp.). This study aimed to establish a basis for revealing the …

Banking For The Future: An Ethnographic Study On The Local Food Bank, Its Role On Food Justice, And Patron Perception, Edward Fernandez

Cal Poly Humboldt theses and projects

Food banks are antithetical to the food justice movement because they usually rely on government commodity surplus to alleviate need and promote notions of dependence through the charity model. This research examines Food for People, the only food bank in Humboldt County, within the context of local food security and patron perception using ethnographic observation, surveys, literature review, and interviews to generate data that would allow the food bank to fulfill its mission of ending hunger. Through ethnographic approaches, this thesis focuses on food security, what affects perception and actual food security in the context of food justice and food …

Impacts Of Elephant Crop-Raiding On Subsistence Farmers And Approaches To Reduce Human-Elephant Farming Conflict In Sagalla, Kenya, Sophia Weinmann

Graduate Student Theses, Dissertations, & Professional Papers

As human and elephant populations grow in Kenya, elephants increasingly leave parks to eat farmers’ crops while foraging, which creates epicenters of human-elephant conflict (HEC). This conflict compromises farmers’ food and economic security, impedes elephant conservation initiatives, and threatens the safety of humans and elephants. In recent years, the situation has been exacerbated by drought and national-level infrastructure development that bisects key elephant habitat. Although researchers have widely studied elephant populations, few have examined the cultural, economic, and emotional effects of HEC on subsistence farmers. This project utilized a mixed methods approach to address this knowledge gap and understand the …

Meat Reimagined: The Ethics Of Cultured Meat, Valan Anthos

Graduate Student Theses, Dissertations, & Professional Papers

In this paper I explore a relatively new technology that is being developed to try and solve some of the major issues with modern animal agriculture called cultured meat. I cover the short history of this technology and where it is at currently before addressing two different ways of evaluating the ethics of cultured meat. Responding to much of the praise for cultured meat based on consequentialist ethics, I lay out reasons for skepticism and how some of these estimates might be overblown due to those people advocating for it being situated in the ideology of ecomodernism. I argue that …

Pig Trauma Models: A Civilian Perspective On Ar-15 Post-Cranial Skeletal Trauma, Lauren M. Kenney

Graduate Student Theses, Dissertations, & Professional Papers

In the last decade, our country has seen an unprecedented wave of terror that has been punctuated by increasing events of gun-related violence. Consequently, the use of firearms against civilians or upon targets containing civilians has inevitably had a direct impact on the health of the individuals affected, and in many cases these events have concluded with mass number fatalities. The driving force for this research falls to the lack of available literature regarding traumatic skeletal injuries associated with high-velocity firearms outside of realm of the military. The effects of these types of weapons on civilians, which result from their …

Ecology, Epidemiology, And Evolutionary Genetics Of Canine Distemper Virus Spillover In African Lions, Julie Kay Weckworth

Graduate Student Theses, Dissertations, & Professional Papers

The impact of emerging infectious diseases (EIDs) on the health and persistence of wildlife populations is an increasing conservation concern. Large carnivores are particularly vulnerable to EID impacts because they often occur in small, isolated populations with demographic and genetic challenges to long-term persistence. Ecological forces that isolate carnivore populations, e.g. agricultural intensification, simultaneously increase the probability of disease exposure from domestic species and can amplify population susceptibility to infection.

Canine distemper virus emerged as a conservation threat to African lions when an explosive epizootic caused the death or disappearance of a third of the Serengeti lion population in 1994. …

The Sylvan Blindspot: The Archaeological Value Of Surface Vegetation And A Critique Of Its Documentation, John S. Harris

Graduate Student Theses, Dissertations, & Professional Papers

Surface vegetation at archaeological sites is a resource overlooked in cultural resource management. Drawing upon comparative documentary surveys of site forms and human surveys of 161 archaeologists in 12 U.S. states, this thesis explores why surface vegetation offers archaeological data potential; how archaeological documentation is an artifact of archaeologists, shaped by various subjectivities; and how improvements can be made for vegetal description in cultural inventory site forms. The surveys offer a critique on how the site form records are a product of disciplinary training oversights, differing work background experience, cultural bias, limitations in botanical knowledge, regional differences in U.S. archaeological …

Strange Rarities, Cori Crumrine

Graduate Student Theses, Dissertations, & Professional Papers

‘Strange Rarities’ is a compelling and odd coupling of words, and similar to this body of work, this phrase both masks and reveals its references. ‘Strange’ defines something unfamiliar or extraordinary; ‘Rarity’ describes something that is uncommon, or the quality of being rare. Paired together, a ‘strange rarity’ refers to an object, a feeling, or a something, which discourages familiarity and excites wonder and awe.

Bottom-Up And Top-Down Controls On Food Webs In Headwater Streams, Miriam O. Bayer

Graduate Student Theses, Dissertations, & Professional Papers

Headwater streams account for 70% of stream channel length in the USA and are important as hotspots of nutrient uptake and native biodiversity. Biofilm, the mixed auto- and heterotrophic microbial community covering stream substrates, is where the majority of nutrient processing occurs, and forms the base of stream food webs, particularly in heavily shaded, oligotrophic streams. Both bottom-up (e.g., nutrients, light) and top-down (i.e., consumption) processes are known to affect periphyton, the autotrophic component of biofilm, but little is known about what controls the biofilm community as a whole. Top-down effects are common in streams, where fish are often the …

Biotic And Abiotic Factors Influencing Infestation Levels Of The Arundo Leafminer, Lasioptera Donacis, In Its Native Range In Mediterranean Europe, Madeline Marshall, John A. Goolsby, Ann T. Vacek, Alexis Racelis

Determination Of Atrazine Concentration In Freshwaters Using Fluorescence Spectroscopy, Boniface Osei Amankona

Online Theses and Dissertations

Atrazine is the most widely used herbicides in USA, but its negative impact on aquatic ecosystem cannot be over-looked. Atrazine was traditionally determined through liquid/gas chromatography or IR spectroscopy. However, these methods are either time-consuming or costly, so fluorescence spectroscopy is investigated as a more cost and time efficient alternative. Literature value of the optimal wavelength of atrazine was found to be 350 nm emission. Experimental value for emission scanned of atrazine resulted in an optimal wavelength of 363 nm. Known and unknown concentrations of atrazine will be analyzed using fluorescence spectrophotometer to develop a calibration curve.

The calibration concentration …

Alcohol Policy Initiatives Of Post-Secondary Institutions In The State Of Kentucky: An Evaluation Of Best Practice Strategies To Reduce Binge Drinking, Deniece Bell

Online Theses and Dissertations

Binge drinking has become a matter of public health. The legal drinking age is 21 in the United States; however, binge drinking by underage college students is prevalent, alarming, and consequential (Malloy & Goldman, 2002). This polarizing topic has caused great concern among policy makers, legal experts, constituents and organizations alike, and as a result they have acted with a sense of urgency to implement policies and evidence-based recommendations for prevention and treatment (U. S. Department of Health and Human Services Alcohol and Health, 1990).

The purpose of this study was to examine the current alcohol policy initiatives among four …

A 2010-2012 survey of Buck Creek by Kentucky Department of Fish and Wildlife Resources personnel observed E. nebra at 2 of 47 historical sites. Within the entire system, individuals were found only in Flat Lick Creek around the confluence of two spring-fed tributaries, Big Spring Branch and Stewart Branch. The objectives of this study were to: (1) determine population size, demographics, and habitat association of E. nebra in Big Spring Branch and Stewart Branch, (2) evaluate habitat conditions both within …

Gene Knockout Of Prfa And The Arginine Deiminase Pathway In Listeria Monocytogenes, Kearstin Edmonds

Online Theses and Dissertations

Listeria monocytogenes is a Gram-positive facultative intracellular pathogen. This species is a common cause of food-borne illness outbreaks with high fatality rates. L. monocytogenes is known to produce a number of virulence factors, including enzymes and toxins, which are involved in the disease process. The arginine deiminase pathway has the ability to regulate acidic environments by converting arginine to ammonia, ornithine, and ATP. With the help of a membrane-bound antiporter, the ornithine is transported out of the cell while the ammonia is converted to ammonium. The ATP by-product can also be used with the F0F1-ATPase system to help maintain homeostasis. …

Development Of An Avian Index Of Biological Integrity For Kentucky Wetlands, Kaitlyn Kelly

Online Theses and Dissertations

Bird communities are frequently used as bioindicators to assess environmental conditions, including in wetland habitats. I developed an avian index of biological integrity (IBI) for wetlands of Kentucky as an intensive assessment method to supplement an existing rapid assessment method used in regulatory programs. Birds are useful indicators because they are sensitive to environmental changes, abundant in various landscapes, occupy higher trophic levels, and can be sampled in a cost-effective manner. Breeding bird point count data from 103 sites were used to calculate a set of 49 avian community metrics. Avian metrics were tested for correlation with independent landscape, hydrology …

Variation In Mass And Wing Loading Of Nestling American Kestrels: Possible Effects Of Nestling Behavior And Adult Provisioning Behavior, Doug Mitchell

Online Theses and Dissertations

Among birds, the rapid growth rates of altricial young help reduce mortality by reducing the amount of time spent in the nest. However, in species where a high degree of maneuverability and speed is required (i.e. aerial insectivores), it is important that nestlings not gain excess weight. Nestlings in some species must attain an efficient wing loading just prior to fledging to facilitate mobility for hunting and evading predators. My objective was to examine the mass of nestling American Kestrels (Falco sparverius) during the mid- to late nestling period and specifically to determine the possible effects of attaching small lead …

Kentucky 4-H Minimizes Barriers To Stem Education, Rachel Elizabeth Noble

Online Theses and Dissertations

Science, Technology, Engineering, and Math (STEM) programs are a national priority. The increase in the number of jobs that require a STEM-minded workforce raises the demand for education systems and communities to focus on fostering the development of STEM competencies of students. American youth are not gaining the skills necessary to compete in the global workforce. This study investigates how Kentucky 4-H minimizes the barriers of accessing STEM programs for youth in grades 4-8. Barriers of accessing STEM programs investigated are: lack of funding and resources, time, professional development, integration across curriculum, and out-of-school experiences. 4-H is the largest youth …

Do Different Music Genres Differentially Affect Autonomic Activity? How Music And Sound Affect Autonomic Activity Aroused By Visual Stimuli, Andrew Manson

Online Theses and Dissertations

The primary researcher sought to determine whether different genres of music would differentially influence measures of autonomic nervous system activity (heart rate, galvanic skin response) while viewing visual stimuli in a sample of college students. All participants listened to the same songs and music genres and viewed the same International Affective Picture System (IAPS) images. Autonomic nervous system activity was recorded by attaching electrodes to participants' non-dominant hand and torso. Music order presentation and picture order presentation were randomly determined by E-Prime. Heart rate and skin conductance responses were both significant, with melodic metal music inducing greater intensity of responses …

The Role Of Microbial Diversity In Female Reproductive Health: An Analysis Of The Microbiome's Influence On Pregnancy Outcomes In Postparturient Mares, Gabriella Pugh

Online Theses and Dissertations

Birth is initiated by a programmed inflammatory response of the placenta and amniotic fluid carried out by maternal and fetal signals, between 37 and 42 weeks gestation for human females. When the inflammatory response occurs off schedule (prior to 37 weeks gestation), pre-term birth is initiated. Pre-term birth is most commonly associated with a maternal infection that consequently leads to infection of the placenta and amniotic fluid; however, the terms of infection are unclear, as microbiota has been discovered in placental membranes and amniotic fluid of healthy pregnancies. The objective of this study is to challenge the sterile womb hypothesis …
