The Mathematical Continuum: A Haunting Problematic, Liz De Freitas

The Mathematics Enthusiast

The mathematical continuum has a number of formulations and technical definitions. Two of these reference the geometric line and the real number system. This conceptual coupling of line and number has been an enduring source for mathematical invention and paradox. The continuum captures the monstrous desire of mathematics, a desire to re-assemble the point with the line, the discrete with the continuous, the finite with the infinite. This paper explores how the continuum is a source of fundamental ambiguity fueling our desires and fears about mathematics.

Possibilities For Mathematics Education? Aphoristic Fragments From The Past, Hilary Povey, Gill Adams

The Mathematics Enthusiast

Our contribution to this special issue is not intended to offer a theoretical argument in conversation with the papers which form The Disorder on Mathematics Education (Straehler-Pohl, Bohlmann & Pais 2017). It is informed by much of the thinking contained therein and driven by a similar concern with the institutionalisation (and therefore the inevitable co-option and colonisation) of the socio-political dimensions of academic research in mathematics education. However, it is intended to sit alongside as a disorderly and comparatively uninvited guest at the conversation. Rather than advocating a specific set of approaches to the teaching and learning of mathematics for …

Why Does Drought Kill Trees? Interactions Between Water, Carbon, And Fungal Symbionts, Gerard Sapes De Moreta

Graduate Student Theses, Dissertations, & Professional Papers

One of the global causes of forest die-off is climate-change induced drought. Drought kills trees by reducing water supply and non-structural carbohydrate (NSC) availability and by increasing susceptibility to negative biotic interactions. However, we lack an understanding of how water, NSC, and biotic agents interact. As a result, we still cannot accurately predict drought-induced mortality. The overarching goal of my dissertation is to increase our understanding of the interacting mechanisms leading to drought-induced mortality (DIM) and to identify physiological variables that accurately predict risk of DIM. Via greenhouse experiments with Pinus ponderosa (ponderosa pine) seedlings, I addressed three overarching research …

A Decade Of Governing The Blackfoot Community Conservation Area (Bcca): Community Involvement And Landscape Connectivity Through Public Private Partnerships, Alexander A. Barton

Graduate Student Theses, Dissertations, & Professional Papers

In recent decades, non-governmental organizations have acquired and established community forests and conservation areas in the U.S. However, there have been few empirical studies on their governance. This study focuses on the Blackfoot Community Conservation Area (BCCA) in the Blackfoot watershed of Montana, created in 2005. The BCCA is a 41,000 acre mosaic of private, state, and federal lands, including 5,600 acres known as the “Core” located near Ovando mountain and owned by the Blackfoot Challenge, a local watershed organization and leader in grassroots conservation. This research examined the definitions, activities and lessons learned over the past decade with regard …

Spatial Patterns Of Winter Roadside Gray Wolf Sightability In Yellowstone National Park, Jeremy Sunderraj

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Imperfect detection is ubiquitous among wildlife research and can affect research conclusions and management. Detection probability is often included in observation-based models. We leveraged research of gray wolves (Canis lupus) in northern Yellowstone National Park (YNP) to evaluate how the probability of sighting radio collared wolf packs from ground-based observation locations was affected by the characteristics of each spatial location (i.e., distance from the road, visibility (from a viewshed analysis), habitat openness, carcass presence, and wolf group size). We used two complementary approaches focusing on sightings during early (mid-November to mid-December) and late (March) winter periods between 1995 and 2017. …

Differential Decomposition Rates Of Non-Human Remains With The Facilitation Of Sodium Hydroxide In Dissimilar Deposition Environments, Hayley Savage

Graduate Student Theses, Dissertations, & Professional Papers

Dissolving bodies is a contemporary method of disposing human remains and has been practiced throughout the years. In popular media, criminals attempt to dispose of their victims by using various chemicals to dissolve the corpses. There is an immense gap in the literature pertaining to this research, so this present study aims to combat the lack of information on the topic. This research investigates the effects of sodium hydroxide (NaOH), generally known as lye or caustic soda, a common household chemical, on human tissues and bone by using an animal analogue (domestic pig, Sus scrofa domesticus). Four dissimilar deposition environments …

The Enduring Importance Of Wildness: Shepherding Wilderness Through The Anthropocene, Patrick Ram Kelly

Graduate Student Theses, Dissertations, & Professional Papers

Wilderness and wildness have long been essential values at the heart of American conservation. Both have played critical roles in the formation of environmental ethics, providing a conceptual foundation for the belief that the non-human natural world is valuable for its own sake (Nash, 2001). After grounding and inspiring much of 20th century environmentalism, their influence in the current century has grown increasingly tentative. The arrival of what some have called the “Anthropocene epoch” – a term meant to capture the planetary scale impacts of human activity – now threatens the continued viability and relevance of wilderness and wildness to …

Into The Wilds: Influences From Video Games On Our Perception Of 'Nature', Toryn W P Rogers

Graduate Student Theses, Dissertations, & Professional Papers

In this paper I examine how representations of human-sparse natural environments, e.g. wilderness, influence what expectations we have when we actually engage with comparable physical places. I use Don Ihde's phenomenology of technology to describe my own experiences playing three games that take place among large photorealistic human-sparse natural environments: Elder Scrolls V: Skyrim, Horizon Zero Dawn, and theHunter: Call of the Wild. I also conduct a brief literature review on the effects of video games as interactive media on players. I argue that players are capable of applying their expectations of what constitutes realism from digital to physical environments, …

#Iownit, Margaret M. Hamilton

Graduate Student Theses, Dissertations, & Professional Papers

Throughout the United States and particularly the West, public lands make up a large portion of land areaand are a vital, reusable, renewable resource that anyone can use. This body of work provides a visual representation of public land users. I’m looking at different user groups representing different activities, ages, genders, and geographic locations. My goal for this work is to make a visual impact on the public’s perspective of how these lands are use, and the people who use them.

All of these public land users have one thing in common: a sense of responsibility for the land, for …

Demographics And Growth History Of Whitebark Pine On Undisturbed Sites Across The Northern Us Rocky Mountains, Sarah Flanary

Graduate Student Theses, Dissertations, & Professional Papers

Along with fluctuating precipitation and temperatures in the form of climate change, whitebark pine (Pinus albicaulis) has seen a territory wide increase in mortality leading to a decline in population. While the most direct influences on whitebark pine health and mortality are mountain pine beetle (Dendroctonus ponderosae) outbreaks, fire exclusion policies, and the spread of white pine blister rust (Cronartium ribicola), climate change can impact the intervals and severity of such beetle, rust, and fire disturbances, and may affect the growth and health of whitebark pine directly. The objectives of this study were to identify whitebark pine stands within the …

Life On The Edge: Risk Of Predation Drives Selection Of Habitat And Survival Of Neonates In Endangered Sierra Nevada Bighorn Sheep, Shannon Forshee

Graduate Student Theses, Dissertations, & Professional Papers

Long-term viability of endangered populations requires development of effective management strategies that target the population vital rate with the highest potential to influence population trajectories. When adult survival is high and stable, juvenile recruitment is the vital rate with the greatest potential to improve population trajectories. For my thesis I examined how lactating Sierra Nevada Bighorn sheep (Ovis Canadensis sierra) balance forage and predation risk during the neonatal period. I first identified resource selection strategies employed by lactating females to promote survival of neonates and then determined the primary factors affecting survival of neonates. I found lactating females selected for …

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 …

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 …

Quantifying False Positives In Avian Survey Data, Kaitlyn M. Strickfaden

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Imperfect detection is a known issue when conducting count-based surveys in wildlife studies. False positive detections, observed occurrences of individuals that truly are not present, are often assumed to not occur. This assumption can bias detection rates and create misleading results when calculating population estimates. Survey methods such as the dependent double-observer method are suggested to reduce the occurrence of false positives (Nichols et al. 2000). My study quantified and compared rates of false positives in a single-observer method and a dependent double-observer method using computer-generated auditory surveys. I categorized volunteer observers as either inexperienced or experienced and asked them …

In my second piece, I describe my field and lab experience working for the Montana Department of Environmental Quality. During this time, …

Polar Gigantism And Sea Spiders: A Study Of Respiratory Scaling, Steven Joseph Lane

Graduate Student Theses, Dissertations, & Professional Papers

All animals must breathe to survive. The types of primary respiratory structures vary across the metazoa, and the overall size and components of these structures scale with body size. The scaling of respiratory structures has been well studied in vertebrate lungs and gills, but very few, if any studies, have looked at it in terms of cutaneous gas exchange, the process where oxygen moves across the outer integument via diffusion. My dissertation has sought to fill this gap in knowledge by studying animals that use cutaneous respiration, and my work has determined both how the components of their respiratory surfaces …
