    • Applying the environmental identity development model in place-based education: an online resource guide

      Blake, Margaret R.; Green, Carie; Hogan, Maureen; Conner, Laura (2020-12)
      I created an online resource guide for place-based education (PBE) informed by the Environmental Identity Development (EID) Model and research (Green et al., 2016). The EID Model provides a flexible framework for understanding how individuals develop their sense of self within and in relation to the natural world. The model is valuable as a diagnostic tool and a guide in the creation of place-based activities that support children’s play, learning, and growth in nature. The goals of this project were to create an accessible guide to understanding the EID Model and theory; to demonstrate how the EID Model and research may be used in the development of culturally relevant educational strategies; to utilize the EID Model in the creation and curation of effective and flexible PBE activities. Qualitative data from the EID research project were used to explain and contextualize the EID Model. Place-based pedagogies and land education pedagogies were utilized in the development of educational resources. The educational resources created for the website are accessible and flexible, adaptable for diverse ages and environments. The website encourages adults to support “spontaneous” child-initiated activities and explorations in the natural world. Ultimately, this guide is an accessible resource that encourages educators to utilize the EID Model in the pursuit of culturally responsive and child-centered PBE in their own context.
    • A Bayesian mixed multistate open-robust design mark-recapture model to estimate heterogeneity in transition rates in an imperfectly detected system

      Badger, Janelle J.; McIntyre, Julie; Barry, Ron; Goddard, Scott; Breed, Greg (2020-12)
      Multistate mark-recapture models have long been used to assess ecological and demographic parameters such as survival, phenology, and breeding rates by estimating transition rates among a series of latent or observable states. Here, we introduce a Bayesian mixed multistate open robust design mark recapture model (MSORD), with random intercepts and slopes to explore individual heterogeneity in transition rates and individual responses to covariates. We fit this model to simulated data sets to test whether the model could accurately and precisely estimate five parameters, set to known values a priori, under varying sampling schemes. To assess the behavior of the model integrated across replicate fits, we employed a two-stage hierarchical model fitting algorithm for each of the simulations. The majority of model fits showed no sign of inadequate convergence according to our metrics, with 81.25% of replicate posteriors for parameters of interest having general agreement among chains (r < 1.1). Estimates of posterior distributions for mean transition rates and standard deviation in random intercepts were generally well-defined. However, we found that models estimated the standard deviation in random slopes and the correlation among random effects relatively poorly, especially in simulations with low power to detect individuals (e.g. low detection rates, study duration, or secondary samples). We also apply this model to a dataset of 200 female grey seals breeding on Sable Island from 1985-2018 to estimate individual heterogeneity in reproductive rate and response to near-exponential population growth. The Bayesian MSORD estimated substantial variation among individuals in both mean transition rates and responses to population size. The correlation among effects trended positively, indicating that females with high reproductive performance (more positive intercept) were also more likely to respond better to population growth (more positive slope) and vice versa. Though our simulation results lend confidence to analyses using this method on well developed datasets on highly observable systems, we caution the use of this framework in sparse data situations.
    • Suicide screening in medical settings screening for suicidality in medical settings: a review of best practices the culturally-grounded interpersonal model for suicide assessment

      Winters, Tomi; Gifford, Valerie; Dahl, Heather; Worrall, Michael (2020-08)
      Suicide assessment training is essential for medical providers because patients are more likely to present at medical clinics than behavioral health clinics when suffering from suicidal ideation (Ahmedani et al., 2014; Luoma, Martin, & Pearson, 2002), and the range in symptom presentation complicates suicide screening (Ghasemi, Shaghaghi, & Allahverdipour, 2015; Giddens, Sheehan, & Sheehan, 2014). Using a survey from the Fairbanks Wellness Coalition (Goldstream Group Incorporated, 2017), a literature review, and three phases of evaluation from prior presentations, this webinar project supports the training needs of medical providers in the Fairbanks North Star Borough. The results from the literature review and feedback from the presentations created the content for the training. Combining suicide risk measurements with clinical judgment is best practice when assessing patients for suicide risk (Bouch & Marshall, 2005; Chung & Jelic, 2015). Use of the C-SSRS and improving clinical judgment with the Culturally-Grounded Interpersonal model for Suicide Assessment (C-GIMS) may improve results. C-GIMS incorporates new findings in the literature after the C-SSRS was created while addressing the need for perspective-taking and cultural attunement for improved clinical judgment. The purpose of this project was to train medical providers to improve screening for suicide risk in medical settings.
    • Open-pit slope geotechnical considerations and its effects on mine planning

      Enkhbayar, Bayasgalan; Chen, Gang; Ahn, Il Sang; Arya, Sampurna (2020-08)
      In open-pit mining, a stable pit slopes design is essential for safe operation and economic performance of the mine. However, a steeper pit is more desirable from an economic standpoint due to reduced overburden removal. As the mine deepens, the open-pit walls become increasingly prone to slope failure, which causes human and economic losses. Therefore, a feasible and stable slope mine design requires a serious geotechnical investigation. The optimization of this design requires steepening the overall slope angle as much as possible while maintaining mine safety for efficient and effective mining operations. The open-pit slope geotechnical investigation calls for detailed geological and geotechnical data and advanced numerical modeling. In this study, geological and geotechnical data are collected from the Erdenet Copper Mine of Mongolia. The collected information includes data from discontinuity face mapping, geotechnical core logging, groundwater condition, geological exploration cross-sections, pit map, and rock property lab test results. The open-pit slope stability is analyzed with geotechnical numerical modeling software FLAC2D, and the variation and distribution of factors of safety (FOS) are computed and studied. The stability of Erdenet mine’s North-West open-pit is simulated by dividing the pit into ten representative cross-sections, and subsequently, FOS is calculated for each cross-section. The simulation results show that each cross-section has a higher overall FOS value than the allowable mine FOS, set at 1.5 with an earthquake magnitude of 0.165g peak ground acceleration (PGA). However, the localized high shear strain on individual benches may still occur, which can cause potential failures. Parametric studies indicate that changes in the bench angles and rock mass properties will have various degrees of impact on pit slope FOS. The effect of bench angle changes appears to be more significant. The study of pit slope design on mine planning shows that a 1° increase on slope angle will reduce excavation volume by 5 M m3 and save $15 million in excavation cost, but will also reduce FOS by 0.12. Engineering judgment and decision will have to be made regarding this tradeoff for a safe and economical mining operation. Practice and analysis indicate that the computer simulation alone is not sufficient to ensure the accurate estimation of slope stability. It is recommended to use a combination of slope monitoring and computer simulation to provide verification against each other to detect any potential hazards in mine. Mine pit slope movement monitoring program setup and monitoring procedure are analyzed and proposed in this study. The above findings allow mining engineers to optimally design pit slopes under the given geotechnical conditions and minimize the risk of slope failures while improving the stripping ratio and enhancing production profit.
    • A Framework for teachers in education for sustainable development for upper elementary grades in the Fairbanks North Star Borough School District

      Wylde, Allison; Green, Carie; Spellman, Katie; Vinlove, Amy (2020-05)
      Education for Sustainable Development (ESD) is a holistic approach to education that seeks to create a better world for this generation and the next. The aim of ESD is for students to gain knowledge, skills, attitudes and values that will shape the planet for a sustainable future. The United Nations has adopted 17 Global Goals as a "universal call to action to end poverty, protect the planet and ensure that all people enjoy peace and prosperity by 2030” (United Nations Development Program, 2020, para. 1). Models for sustainability look very different depending on where one lives. The context of this work is Alaska, and more specifically the Fairbanks North Star Borough. The purpose of this project is to build a website resource to aid teachers in developing a mindset toward ESD and provide locally relevant resources and curriculum aligned with the United Nations Global Goals. This project is guided by the question of how Indigenous Ways of Knowing & Culturally responsive practices can be incorporated into curriculum development alongside district standards and ESD competencies. The methods of this project seek to engage students by incorporating real-world challenges and authentic experiences into core subject areas allowing students to connect classroom learning to real life, and thus creating engaged citizens. The aims are for students to become environmentally aware, while developing life-skills including leadership, communication, collaboration, and management. By developing a sense of place and equipping students with environmental knowledge and skills they can excel at living lives which further humanity while caring for and respecting our planet and it's resources.
    • Ugnu pilot area - simulation model and sensitivity analysis

      Wooster, Arin J.; Dandekar, Abhijit; Ning, Samson; Zhang, Yin (2020-05)
      Collaborating with Hilcorp Alaska, LLC, the Ugnu pilot area is the subject of this project. Hilcorp Alaska is conducting field pilot test at Milne Point Field to prove commerciality with Ugnu heavy oil as well as an on-going Milne viscous oil polymer flood field pilot test in the Schrader Bluff sands. The Ugnu sand heavy oil represents much of the heavy oil on Alaska’s North Slope and has potential for future development. Typical heavy oil has a viscosity of 1,000 - 10,000 centipoise, approximately akin to viscosities of honey and molasses, respectively. North Slope heavy oil is located around 3,000-foot depths and typically overlays existing fields. The project involves a reservoir simulation model and sensitivity analysis to support developmental drilling plans from a Milne Point Unit pad. Necessary geologic and reservoir properties were provided for usage in this project by Hilcorp. Production data was provided for history matching. Field geologic background was also supplied to aid in the understanding of the reservoir. The reservoir simulation model was built using Computer Modelling Group software, namely Builder and IMEX. The first model iteration contained one producer in an 8,500-foot lateral pattern. Further iterations included additional producers and injectors for waterflood and polymer flood studies. Conclusions and recommendations were drawn upon analyzing the reservoir simulation results centering around favorable production strategies, polymer flood performance, comparison to the on-going Milne viscous oil polymer flood pilot, and future polymer flood studies. Completed objectives of this project included: 1. Developing a numerical reservoir simulation model for the Ugnu MB sand in the pilot area; 2. Evaluating the productivity of horizontal wells in the Ugnu MB sand; 3. Predicting ultimate oil recovery with waterflood and polymer flood; 4. Predicting polymer utilization, polymer injected per incremental oil barrels over waterflood.
    • Navigating ambiguous regulations: an artist's perspective on indigenous art materials and resource management in Alaska

      Woldstad, Theresa M.; Mehner, Da-ka-xeen; Croskrey, Wendy Ernst; Mason, Charles; Jones, Zoe Marie; Simpson, Glen (2020-03)
      Alaska Native art is legally defined as art created by a member of a state or federally-recognized tribe of Alaska Natives or a certified non-member artisan (Indian Arts and Crafts Act). Yet this legal definition does not reference the cultural expression and application of creative skill that makes Alaska Native Art a strategic expressive resource. Alaska Native Art is a cultural resource that impacts indigenous economies, cultural social networks, natural resource utilization, and political engagement. Through the creation of native art, an individual not only expresses their culture but also becomes engaged in the natural resource utilization and management in Alaska. However, the link between natural resource management and customary material harvest and utilization has been historically underappreciated primarily due to regulatory ambiguity and broad nature of artistic creation. The harvest and use of these customary materials are governed by multiple state and federal laws across diverse management agencies. State and federal natural resource management agencies possess different interpretations for who may harvest natural resources for art, definitions of significant modifications of natural materials to create art, and priorities governing urban and rural access. Each agency applies different administrative codes to determine proper permitting for both personal artistic creation and the manufacture of marketplace authentic Alaska Native Handicrafts. However, this ambiguous labyrinth of regulation is constantly changing and adapting to new federal and state laws, treaties, and court rules. It is the responsibility of the native artist to navigate this complicated mosaic of regulatory authority to harvest natural materials for art. Yet the foundation from which an artist begins navigating regulatory authority is often inadequately defined. It is the purpose of this MFA thesis is to provide an artist’s perspective on native art materials and resource management in Alaska
    • School counselor's role in recognizing and addressing eating disorders in the Fairbanks Northstar Borough School District

      Widman, Joyce A.; Gifford, Valerie; Cook, Christine R.; McMorrow, Samantha (2020-05)
      Eating disorders are recognized as the deadliest mental-health illness. Eating disorder symptoms frequently appear in adolescents in middle school and high school, which is a time when school counselors are part of a teenager’s life. School counseling offers a solid platform to educate and collaborate with stakeholders such as parents, other school staff, and coaches. Fairbanks, Alaska, like other small communities, lacks resources for the treatment of eating disorders. However, there are dieticians, counselors, and doctors in the local community who are able and willing to work together on behalf of a student struggling with an eating disorder or eating disorder symptoms. They can help with treatment for mild cases and with locating an appropriate venue for in treatment care. Based on an examination of current literature on eating disorders and the roles that school counselors can play in recognition of and treatment for young people with eating disorders, a website and booklet have been developed specifically for school counselors in the Fairbanks North Star Borough School District.
    • A modular LoRaWAN inspired Internet of Things approach to collecting sensor data via Software Defined Radio

      Van Cise, Tristan; Genetti, Jon; Lawlor, Orion; Metzgar, Jonathan (2020-05)
      The emergence of simple Internet of Things (IoT) devices has habituated the ability to efficiently collect data and communicate information between devices with ease. Similarly, Software Defined Radio (SDR) has compacted radio communication into a USB dongle capable of receiving radio signals from most radio transmitters. In this approach, the ease of IoT device communication and versatility of SDR data collection and transmission techniques is combined to monitor building thermal decay. The system developed to collect thermal decay data is adapted from the Long Range Wide Area Network (LoRaWAN) IoT architecture and is designed to facilitate variable size collection environments and real-time data visualization. This paper will outline the implementation and capabilities of the collection system and highlight alternate applications and hardware implementations of the underlying framework.
    • King on ice: history of the Alaska Gold Kings and the transformation of Fairbanks into a hockeytown

      Urban, Samuel Fox; Ehrlander, Mary F.; Boylan, Brandon M.; Speight, Jeremy S. (2020-05)
      Wanting a higher level of hockey for local youth to aspire to, city hockey officials created the semi-professional Teamsters hockey team in 1975. The team was initially comprised of the best local recreational players, many of whom relocated to Fairbanks to work on the TransAlaska Pipeline from the upper Midwest and Seattle. Two years later the team took on the name Fairbanks Gold Kings (later changed to the Alaska Gold Kings), and quickly began proving itself against teams from Anchorage and the Pacific Northwest. From 1975 to 1995 the Gold Kings were an amateur senior men’s team, and from 1995-1997 they spent their last two Fairbanks years in the professional minor league West Coast Hockey League. Between its inception in 1975 as the Teamsters, and in spite of its relocation to Colorado Springs in 1998 as the Alaska Gold Kings, Fairbanks’ team was a huge success. The Gold Kings won five national championships, played 16 different international and Olympic teams, played overseas in Asia and Europe on multiple occasions, and laid the foundation for the level of hockey found in Fairbanks today.
    • Kitkut ukua Siļaliñiġmiut? Grassroots land, air, and water coalition-building on Alaska's Arctic Slope

      Thomas, Sara K. Siqiñiq; Brooks, Catherine; Stern, Charlene; Brower, Pearl (2020-05)
      Arctic communities are experiencing dramatic effects of climate change and bioaccumulation of contamination and are also on the front line of expansion via the fossil fuel extraction industry. The Inupiaq culture provides a strong and clear example of harmonious living with one’s surroundings on Alaska’s Arctic Slope (hereafter referred to as Arctic Slope), yet recent community efforts to reduce waste or pollution or come together to address our role in this time of climate change have been short-lived. This applied community development project addresses the need for grassroots organizing within the Arctic Slope to address and react to issues of land, air, and water on a community level. The title of this research is: Kitkut ukua Siļaliñiġmiut? Who are the people of the land, air, and sea (of the Arctic Slope)? This is a self-reflective inquiry from within the community that aims to uplift Inupiat history and cultural perspectives and develop more effective strategies to collaborate to be better stewards of the environment. This project was guided by the Indigenous consciousness-raising theory and an Iñupiaqatigiigñiq framework, inspired by Topkok’s Inupiat Ilitqusiat (2015). The literature/narrative review comprises an overview of Iñupiaqatigiigñiq, or the Iñupiaq value system, as it relates to Indigenous knowledge. It also includes current and historical perceptions of ecological stewardship and environmentalism on the Arctic Slope, and barriers to social change in contemporary institutional representation. Community-based participatory research and strength-based methodology were utilized to inform data collection, which included a survey as well as a series of community dialogues with a variety of Arctic Slope stakeholders. Community perspectives regarding ecological sustainability were elicited using talking circles and group visioning around these questions: Sumik iļisimavisa Iñupiaqatigiigñiq suli nunalu, siļalu, taġiuglu? What do we know about Iñupiaqatigiigñiq and land, air, and water? Suniaqsimaavisa atusiullaaluta nakka qatilluta? What more can we do (to be better stewards) today as individuals and as communities? Data was analyzed using triangulation and thematic analysis techniques. The themes that emerged from the data were shared and then reshared to the larger community via social media, one-on-one outreach to smaller groups, and a community presentation. This project has resulted in both a data set and a framework for continued community-building and information-sharing around land, air, and water stewardship initiatives. The foundation for a regional grassroots coalition has been established via the collaborative development of a website and social media presence. It is my hope that this project will also inform the development of an after-school youth engagement program that could propel a grassroots network of people working together to foster greater stewardship of the land, air, and water.

    • LucidDream: Dynamic Story Generation through Directed Chatbot Interactions

      Stonebraker, Ryan; Metzgar, Jonathan; Lawlor, Orion; Hartman, Chris (2020-05)
      Natural Language Understanding and Generation are both areas of active research with widespread potential for story telling. This paper proposes an architecture for dynamically generating stories that allows a scene to be constructed and then dynamically written through the interaction of individual chatbots. Each chatbot in this environment is meant to mimic either the specific emotional profile of a character or holistically represent all of the character’s attributes. Chatbots are created using the conversation history so that they can understand context, a relevant sentence suggestion provided by a question-answering model to keep generated output on topic, and a finetuned version of the GPT-2 transformer-based language model to combine all of this information and generate text. This architecture serves as an ensemble method of approaching character modeling and also introduces the little-explored concept of emotional style transferring as a method for merging a story character’s emotional attributes with an independent training corpus. The question-answering model used in this study achieved 65.24% accuracy when tested on the Stanford Question-Answering Dataset and the emotion classification model achieved 57.3% accuracy on the International Survey on Emotion Antecedents and Reactions dataset. While neither of these performances are SOTA for their respective individual tasks, they are used in combination to produce state of the art directed story generation and pave the way for future research.
    • Examining thermokarst initiation with random forest models

      Spicer, Rawser W.; Bolton, W. Robert; Lawlor, Orion; Chappell, Glenn (2020-05)
      This project examines thermokarst initiation through the application of random forest models. Thermokarst initiation marks the start of the formation of thermokarst features. Changes in landscape, due to the thermokarst process, can result in changes in wildlife habitat, as well as energy, carbon and water fluxes. Random forests are an ensemble learning technique that combines the results of many independent decision trees to create results that avoid the overfitting in regular decision trees. Random forests were trained against an existing thermokarst initiation model. Results showed that random forests were useful in this context. Random forest hyperparameters were also examined through a multiparameter sensitivity analysis.
    • Investigation of nanoscale drug particles and their effect on the fluid dynamic properties of the blood

      Slats, Jason L.; Das, Debendra; Zhang, Lei; Misra, Debasmita (2020-05)
      Research has shown that gold nanoparticles increase the efficiency of radiation treatments of cancer by up to 25%. This means patients can be exposed to lower doses of radiation that does more concentrated damage to cancerous cells and less damage to healthy surrounding tissue. Before these nanoparticles can be introduced to the human body, the behavior of these particles in the blood stream must be understood. A model of gold nanoparticle flow through the aortic arch was developed in the present investigation for predicting behavior of these particles in the human body. A set of initial modeling parameters was developed out of existing data pertaining to blood flow rates and viscosities of a blood-mimicking fluid across a temperature range of 30-40 degrees Celsius. The aorta wall was modeled as a no-slip solid surface. Computational fluid dynamic models using ANSYS Fluent across this temperature range have generated general velocity distributions of blood flow through the aortic arch and identifies several areas of possible recirculation. The current state of the model provides preliminary results, which are valuable in generating an accurate model of gold nanoparticles flowing through the aortic arch.
