Results from the study indicate that student achievement in Reading …

Spatial Transferability Assessment Of A Composite Walkability Index: The Pedestrian Index Of The Environment (Pie), Gabriel Lefebvre-Ropars, Catherine Morency, Patrick A. Singleton, Kelly J. Clifton

Civil and Environmental Engineering Faculty Publications and Presentations

This paper analyzes the transferability of a composite walkability index, the Pedestrian Index of the Environment (PIE), to the Greater Montréal Area (GMA). The PIE was developed in Portland, Oregon, and is based on proprietary data. It combines six urban form variables into a score ranging from 20 to 100. The measure introduces several methodological refinements which have not been applied concurrently in previous efforts: a wide coverage of the different dimensions of the urban form, together with the use of a distance-based decay function and modelling-based weighing of the variables.

Natural Histories Of Yup'ik Memoirs, Caroline R. Crecelius

Anthropology

This thesis explores how cultural knowledge is committed to textual form and circulated within and outside of linguistically marginalized communities. Working within a Central Yup'ik context, I have focused my research on collections of Yup'ik elders' memoirs housed within the Alaska Native Language Archive. Published Yup'ik elders' memoirs offer rich descriptions of Yup'ik cultural histories, epistemologies and statements about language, the expression and inclusion of which varies based on the interactional contexts, participant frameworks and funding institutions through which they were produced. This study incorporates both Indigenous and non-Indigenous theoretical frameworks related to the process of entextualization, or text creation, …

Justice

The present Master's project seeks to develop a better understanding of Veterans and what they are going through. Research methods include extensive data on the high suicide rates of Veterans. Veteran and service members are in need of a service to them that will address the issue of suicide and what can be done to help and eliminate this problem. The programs that need to be designed to help needs should be in locations that have Veteran populations so as to serve them with their needs. Ultimately, Veterans Affairs (VA) officials have boosted their mental health personnel and suicide hotline …

Bringing Twygs To Life: Pace Based Lessons In An Adult Esl Classroom, Erica Harris

Linguistics

English grammar is a daunting subject for language learners and teachers alike. Traditionally, grammar is taught in an explicit manner in a teacher-fronted classroom. Rules are given and explained to students, who then practice with drills and example problems. As an alternative approach to teaching grammar, this project incorporates the PACE model (Presentation, Attention, Co-Construction, Extension) and task-based language teaching (TBLT). This method of teaching is a departure from traditional explicit-style teaching, and focuses more on the learner's role in the classroom than on the teacher's role. The PACE model uses stories to teach grammar, in this case English prepositions. …

Evaluation Of Growth And Migration Trends On The Survival And Recruitment Of Chinook Salmon In Southeastern Alaska Rivers, Stephanie Berkman

Fisheries

Highly variable recruitment and declines in productivity and abundance of Chinook Salmon Oncorhynchus tshawytscha have created economic and cultural hardships for communities throughout Alaska. Although pre- and post-smolt growth are important for determining brood-year (BY) survival and productivity for Pacific salmon through size-mediated mortality, these relationships remain unclear for Chinook Salmon. As a result, it is necessary to better understand the relationships between environmental and biological factors that influence freshwater and marine growth, smolt outmigrations, and recruitment success. This study used retrospective growth to identify the importance of annual growth in determining BY survival and recruitment, determine if growth dependency …

Interdisciplinary Assessment Of The Skate Fishery In The Gulf Of Alaska, Thomas J. Farrugia

Fisheries

Skates are common bottom-dwelling fishes and valuable non-target species in Gulf of Alaska fisheries. Although there is little demand for skates in the United States, markets in Europe and Asia are fueling desires for additional fishing opportunities on skates in Alaska. Management agencies, however, have been hesitant to allow increased harvests due to the lack of information on the ecology and population dynamics of skates, and the bioeconomics of skate fisheries. Specifically focusing on the two most commonly landedskate species in the Gulf of Alaska (GOA), the big skate (Beringraja binoculata) and the longnose skate (Raja rhina), I conducted an …

Trace Metals In Arctic Fast Ice, Vincent Domena

Oceanography

Trace metals in the marine environment are found in trace amounts, but are important tracers of oceanographic processes, and bioactive trace metals can impact ocean biogeochemistry through their nutrient or toxic influence of microbial populations. Sea ice is an intrinsic feature of the Arctic Ocean that likely plays a key role in the cycling of trace metals, given that this substrate can concentrate, alter, and transport these elements. Warming conditions in the Arctic have decreased sea ice cover over the past decades and the loss of sea ice threatens to drastically change the Arctic ecosystem, but the implications are not …

Circulation And Dynamics On The Northeastern Chukchi Sea Shelf, Ying-Chih Fang

Oceanography

The circulation on the northeastern Chukchi Sea shelf is controlled by the poleward pressure gradient between the Pacific and Arctic Oceans. Local winds modulate the upper ocean and can rapidly alter the flow field. Present understanding of the circulation is largely based on subsurface measurements, but the response of near-surface currents to the slowly-varying secular pressure gradient and rapidly-varying local winds has not been addressed. I analyzed surface current data, extending more ~150 km offshore in the northeastern Chukchi Sea, collected from shore-based high-frequency radar systems (HFR) during the open water season. I find three wind-induced circulation regimes. Two of …

Experimental And Numerical Simulation Of Hydraulic Fracturing, Mohammad Hoveidafar

Engineering

Hydraulic Fracturing (HF) has many applications in different fields such as stimulation of oil and gas reservoirs, in situ stress measurements, stress relief for tunneling projects as well as in underground mining applications such as block caving mining. In the HF process, high pressure fluid is injected into a well to generate fractures in tight rock formations. This technique is particularly suitable for developing hydrocarbon energy resources in tight rock formations such as shale with very low permeability. An experimental setup was designed and developed to simulate the HF process in the laboratory. Cubic plaster specimens were molded and HF …

Long Term Evaporation Pan Data To Estimate Potential Evaporation During The Warm Season On The Alaskan North Slope: Imnavait Creek Basin, John Paul Mumm

Engineering

Evapotranspiration plays a significant role in the hydrologic cycle of all basins, yet is only ccasionally measured in the Arctic. One simple index method to evaluate evapotranspiration is the evaporation pan. The energy environment surrounding the simple evaporation pan varies considerably from that of the natural environment. Yet, an evaporation pan is a sound way to determine and estimate the potential evapotranspiration, and actual evapotranspiration can be estimated from evaporation pan data by determining and employing a pan coefficient. An evaporation pan was initially installed in 1986 in the northern foothills of the Brooks Range on the North Slope of …

Automatic Detection Of Sensor Calibration Errors In Mining Industry, Rambabu Pothina

Engineering

Sensor errors cost the mining industry millions of dollars in losses each year. Unlike gross errors, "calibration errors" are subtle, develop over time, and are difficult to identify. Economic losses start accumulating even when errors are small. Therefore, the aim of this research was to develop methods to identify calibration errors well before they become obvious. The goal in this research was to detect errors at a bias as low as 2% in magnitude. The innovative strategy developed relied on relationships between a variety of sensors to detect when a given sensor started to stray. Sensors in a carbon stripping …

Connecting Alaskans: Mixed-Use Safety And Accessibility Challenges In Rural Environments, Carrie L. Sorensen

Engineering

Connectivity in transportation networks, or lack thereof, is a challenge that many people have to deal with. Alaska has many rural communities that are inaccessible by conventional modes of transportation. In order for people to reach these communities and move between them unconventional modes of transportation are needed. However, very few studies have been done on unconventional transportation modes such as ATVs and snowmachines and the level to which they contribute to connecting people and how to help limit traumatic injuries of users. This study focuses on Alaska and three primary datasets. First, the Pacific North West Transportation Survey developed …

Social-Ecological Soundscapes: Examining Aircraft-Harvester-Caribou Conflict In Arctic Alaska, Taylor R. Stinchcomb

Biological Sciences

As human development expands across the Arctic, it is crucial to carefully assess the impacts to remote natural ecosystems and to indigenous communities that rely on wild resources for nutritional and cultural wellbeing. Because indigenous communities and wildlife populations are interdependent, assessing how human activities impact traditional harvest practices can advance our understanding of the human dimensions of wildlife management. Indigenous communities across Arctic Alaska have expressed concern over the last four decades that low-flying aircraft interfere with their traditional harvest practices. For example, communities often have testified that aircraft disturb caribou (Rangifer tarandus) and thereby reduce harvest opportunities. Despite …

Arctic Landscape Dynamics: Modern Processes And Pleistocene Legacies, Louise M. Farquharson

Geosciences

The Arctic Cryosphere (AC) is sensitive to rapid climate changes. The response of glaciers, sea ice, and permafrost-influenced landscapes to warming is complicated by polar amplification of global climate change which is caused by the presence of thresholds in the physics of energy exchange occurring around the freezing point of water. To better understand how the AC has and will respond to warming climate, we need to understand landscape processes that are operating and interacting across a wide range of spatial and temporal scales. This dissertation presents three studies from Arctic Alaska that use a combination of field surveys, sedimentology, …

Satellite Remote Sensing Of Active Wildfires In Alaska's Boreal Forest, Christine F. Waigl

Geosciences

This research addresses improvements to the detection and characterization of active wildfires in Alaska with satellite-based sensors. The VIIRS I-band Fire Detection Algorithm for High Latitudes (VIFDAHL) was developed and evaluated against existing active fire products from the Visible Infrared Imaging Radiometer Suite (VIIRS) and the Moderate Resolution Imaging Spectroradiometer (MODIS). This new algorithm is based on VIIRS 375 m spatial resolution imagery and was tuned using fires in Alaska's boreal forest. It provides improved fire detection of low-intensity fires, especially during daytime and at sensor zenith angles smaller than approximately 50° off nadir. Low-intensity active fires, which represent residual …

The Qualitative Report

Romantic turmoil is something that most people experience in their life. When faced with an upsetting event, such as a breakup or fight with a partner, a person may turn to music to achieve a more desirable state of mind. The current study extended past research on music and coping by focusing specifically on a person’s use of music when they have emotional distress due to a romantic event. Ten interviews revealed the major theme “Music as a Tool,” regarding how people use music as social support. The first subtheme, Alliance with Mood, describes how participants used music as a …

Researcher Emotions As Data, A Tool And A Factor In Professional Development, Liora Nutov

The Qualitative Report

The purpose of this paper is to explore and reflect on my own emotions while carrying out a research process and on their effect on the research and on myself as a researcher. After a brief literature review of the ways in which researcher emotions are perceived in qualitative research in the field of social sciences, I offer a reflective account of my own experience and suggest that researcher emotions can serve both as additional data and as an analyzing tool, as well as being a factor in the professional development of researchers.

Following The Flâneur: The Methodological Possibilities And Applications Of Flânerie In New Urban Spaces, Jessica Rizk, Anton Birioukov

The Qualitative Report

This paper considers the historic concept of flânerie, the act of “strolling” through urban spaces, as an unconventional approach to gathering qualitative data. In adopting a flânerie identity, the researcher is able to critically analyze urban spaces and the relation of self to those spaces. Through a (re)conceptualization of the 19th century flâneur, we explicate the methodological possibilities and applications of flânerie, in particular, as suited to excavating new urban tropes, whilst giving expression to new urban subjectivities. The authors adopt a flânerie identity, engaging in a qualitative inquiry vis-à-vis two “strolls” occurring in Toronto, Canada. The strolls provide opportunities …

WERC Project Reports

The Dalton Highway near Deadhorse was closed twice during late March and early April 2015 because of extensive overflow from the Sagavanirktok River that flowed over the highway. That spring, researchers from the Water and Environmental Research Center at the University of Alaska Fairbanks (UAF) monitored the river conditions during breakup, which was characterized by unprecedented flooding that overtopped and consequently destroyed several sections of the Dalton Highway near Deadhorse. The UAF research team has monitored breakup conditions at the Sagavanirktok River since that time. Given the magnitude of the 2015 flooding, the Alyeska Pipeline Service Company started a long-term …

The Perimeters Of Familial Affection: Examples With The Metamorphosis, The Sooterkin, And "A Very Old Man With Enormous Wings", Summer Dorr

English

This literary analysis--of Franz Kafka's The Metamorphosis, Tom Gilling's The Sooterkin, and Gabriel García Márquez's "A Very Old Man with Enormous Wings"-- asserts that unconditional love is not possible without a supernatural impartation, because all humans have their limitations. To further this claim, I dissect the most sacred of interpersonal dynamics, society's subgroups--the family. The four guiding perimeters of affection are societal influence--its opinion of a person; money, financial prospect; communication aptitude, whether verbal and physical speech that is understood or enjoyed; and, lastly, aesthetics: are they nondescript or pleasant to the eye? These variables determine how long a person …

Straying, Stress, And Potential For Reproductive Interactions Between Hatchery-Produced And Wild Chum Salmon (Oncorhynchus Keta) In Southeast Alaska, Casey John Mcconnell

Fisheries

Approximately 1.5 billion juvenile hatchery-produced Pacific salmon (Oncorhynchus spp.) are currently released each year into Alaskan waters with goals of enhancing important fisheries and minimizing detrimental impacts on wild stocks. As the abundance of hatchery-produced salmon has increased, so have concerns about hatchery-origin strays entering wild systems and interactions with wild individuals on the spawning grounds. The influx of non-native strays and their associated fitness-related traits can reduce the resilience and productivity of recipient wild stocks, and is likely to be most deleterious when disparities in population sizes and heritable phenotypic characteristics between wild and hatchery fish exist. Thus, understanding …

Migration Patterns And Energetics Of Adult Chinook Salmon Oncorhynchus Tshawystcha In Alaska Rivers, Kristin R. Neuneker

Fisheries

Adult Chinook Salmon Oncorhynchus tshawytscha undertake extensive and energetically costly migrations between food resources in the ocean and their freshwater spawning habitats, requiring them to adapt behavioral and physiological traits that allow them to successfully reach their spawning streams and reproduce. Such adaptations may be shaped by physical factors in the environment and individual- and population-specific biological characteristics. Chinook Salmon in North America are important resources for both United States and Canadian stakeholders, but relatively little is known about their freshwater migration patterns and energetic status in many rivers across their range. This research explored variation in migration timing and …

Estimating Sizes Of Fish Consumed By Ice Seals Using Otolith Length-Fish Length Relationships, Kelly Walker

Fisheries

Arctic fishes and ice seals are key components of the Alaskan Arctic ecosystem. Bearded (Erignathus barbatus), spotted (Phoca largha) and ringed (Pusa hispida) seals are consumers of Arctic marine fishes. Little is known about the sizes of fish that ice seals consume because prey items are digested quickly once exposed to stomach acids. Otoliths, fish ear bones, are often the only parts of a fish that remain in a seal stomach. Otolith length relates directly to fish length, making size estimations of consumed fish possible for piscivore diet studies. Otoliths were measured from fishes collected from cruises in the Beaufort …

Diets Of Four Eelpout Species (Genus Lycodes) In The U.S. Beaufort Sea Based On Analyses Of Stomach Contents And Stable Isotopes Of Nitrogen And Carbon, Sarah J. Apsens

Fisheries

Eelpouts of the genus Lycodes are an abundant group of demersal fishes in the U.S. Beaufort Sea. Currently eelpout diet and the exact role of eelpouts in the Arctic food web are poorly understood. Additionally, if and how eelpouts avoid intra- and interspecific competition for resources is unknown. In this study, diets of four common Beaufort Sea eelpout species were analyzed with respect to along-shelf (longitude) gradients, across-shelf (depth) gradients, and ontogeny (fish body length) to determine diet composition and patterns of resource partitioning. Diets of the four most numerous eelpout species were analyzed using a combination of stomach contents …
