  • Formerly used defense sites on Unalaska Island, Alaska: Mapping a legacy of environmental pollution

    Jordan‐Ward, Renee; Hippel, Frank A; Schmidt, Jennifer (John Wiley and Sons, 2024-02-14)
    Unalaska Island, Alaska, served as a US military base during World War II. The military installed bases on Unalaska and nearby islands, many of which were built adjacent to Unangan communities. The military used toxic compounds in its operations and left a legacy of pollution that may pose health risks to residents and local wildlife. The goals of this study were to identify hotspots of contamination remaining at Unalaska formerly used defense (FUD) sites, evaluate the risk posed by arsenic, and examine “no US Department of Defense action indicated” (NDAI) status determinations for FUD sites near communities. We compiled soil chemistry data from remediation reports prepared by the US Army Corps of Engineers at 18 FUD sites on and near Unalaska. Nine had past and/or active remediation projects and on-site sampling data. Eight sites did not have sampling data and were characterized as NDAI. One site was listed as closed. For the nine sites with sampling data, we compiled data for 22 contaminants of concern (COC) and compared concentrations to soil cleanup levels for human health (18 AAC 75.341). We mapped contaminant concentrations exceeding these levels to identify hotspots of contamination. We found that concentrations of some of the 22 COC exceeded Alaska cleanup levels despite remediation efforts, including diesel range organics, arsenic, and lead. The highest COC concentrations were at the FUD site adjacent to the City of Unalaska. A quantitative risk assessment for arsenic found that the risk of exposure through drinking water is low. We highlight concerns with NDAI designations and current remedial practices at remote FUD sites located adjacent to communities. Our data suggest the need for further remediation and monitoring efforts on Unalaska for certain contaminants and research to examine potential threats to human and animal health associated with these sites.
  • Engagement with mHealth Alcohol Interventions: User Perspectives on an App or Chatbot-Delivered Program to Reduce Drinking

    Sedotto, Robyn N. M; Edwards, Alexandra E.; Dulin, Partick L.; King, Diane K. (MDPI, 2024-01-02)
    Research suggests participant engagement is a key mediator of mHealth alcohol interventions’ effectiveness in reducing alcohol consumption among users. Understanding the features that promote engagement is critical to maximizing the effectiveness of mHealth-delivered alcohol interventions. The purpose of this study was to identify facilitators and barriers to mHealth alcohol intervention utilization among hazardous-drinking participants who were randomized to use either an app (Step Away) or Artificial Intelligence (AI) chatbot-based intervention for reducing drinking (the Step Away chatbot). We conducted semi-structured interviews from December 2019 to January 2020 with 20 participants who used the app or chatbot for three months, identifying common facilitators and barriers to use. Participants of both interventions reported that tracking their drinking, receiving feedback about their drinking, feeling held accountable, notifications about high-risk drinking times, and reminders to track their drinking promoted continued engagement. Positivity, personalization, gaining insight into their drinking, and daily tips were stronger facilitator themes among bot users, indicating these may be strengths of the AI chatbot-based intervention when compared to a user-directed app. While tracking drinking was a theme among both groups, it was more salient among app users, potentially due to the option to quickly track drinks in the app that was not present with the conversational chatbot. Notification glitches, technology glitches, and difficulty with tracking drinking data were usage barriers for both groups. Lengthy setup processes were a stronger barrier for app users. Repetitiveness of the bot conversation, receipt of non-tailored daily tips, and inability to self-navigate to desired content were reported as barriers by bot users. To maximize engagement with AI interventions, future developers should include tracking to reinforce behavior change self-monitoring and be mindful of repetitive conversations, lengthy setup, and pathways that limit self-directed navigation.
  • Review of Diagnostic Methods

    Edwards, Alexandra (ACSES, 2002-07-31)
    As part of the conditions of funding the statewide Alaska FAS Prevention Project, SAMHSA requested that the project be evaluated by an independent team of evaluators. This evaluation contract was awarded to the Center for Human Development (CHD) at the University of Alaska Anchorage (UAA), with the request that the evaluation be conducted by an interdisciplinary team of evaluators from across the UAA campus. Staff at CHD subsequently selected various professionals from the UAA community to build the Evaluation Team and to divide the work involved in the evaluation of the FAS Prevention Project. The FAS Project Principal Evaluation Team selection began in February 2001 (3rd Quarter of FY 01 of the grant). In August 2001, a comprehensive evaluation plan was submitted to the FAS Advisory Team and State Office of FAS for review and approval. Following submittal of the evaluation plan application to the University of Alaska Institutional Review Board (IRB) and receipt of funding from the state in August 2001, the detailed actions defined in the Diagnostic Evaluation Plan were initiated in October 2001 (2nd Quarter of FY 02 of the grant). The Alaska Comprehensive and Specialized Evaluation Services (ACSES) was one of the groups approached by CHD to participate as a member of the FAS Project Principal Evaluation Team. ACSES was honored to take on the evaluation of diagnosis-related activities, committing to activities to meet five large goals. One of these goals was the review of FAS diagnostic methods that have been used in Alaska and across the United States. This report provides an update on activities and findings about this goal to date.
  • Adapting adaptive design methods to accelerate adoption of a digital asthma management intervention

    King, Diane K.; Bender, Bruce G.; Cvietusa, Peter J.; Goodrich, Glenn K.; Shoup, Jo Ann (Center for Behavioral Health Research and Services, University of Alaska Anchorage, Anchorage, AK, USA, 2023)
    Investigators conducting translational research in real-world settings may experience changes that create challenges to the successful completion of the trial as well as post-trial adoption and implementation. Adaptive designs support translational research by systematically adapting content and methods to meet the needs of target populations, settings and contexts. This manuscript describes an adaptive implementation research model that provides strategies for changing content, delivery processes, and research methods to correct course when anticipated and unanticipated circumstances occur during a pragmatic trial. The Breathewell Program included two large pragmatic trials of the effectiveness of a digital communication technology intervention to improve symptom management and medication adherence in asthma care. The first trial targeted parents of children with asthma; the second targeted adults with asthma. Adaptations were made iteratively to adjust to dynamic conditions within the healthcare setting, informed by prospectively collected stakeholder input, and were categorized retrospectively by the authors as proactive or reactive. Study outcomes demonstrated improved treatment adherence and clinical efficiency. Kaiser Permanente Colorado, the setting for both studies, adopted the speech recognition intervention into routine care, however, both interventions required numerous adaptations, including changes to target population, intervention content, and internal workflows. Proactive and reactive adaptations assured that both trials were successfully completed. Adaptive research designs will continue to provide an important pathway to move healthcare delivery research into practice while conducting ongoing effectiveness evaluation.
  • 'The park a tree built': Evaluating how a park development project impacted where people play

    Litt, Jill; Hale, James; Burniece, Katherine M.; Ross, Colleen; King, Diane K. (Center for Behavioral Health Research and Services, University of Alaska Anchorage, Anchorage, AK, USA, 2015-12)
    Community parks have achieved recognition as a public health intervention to promote physical activity. This study evaluated changes in population-level physical activity when an undeveloped green space adjacent to transitional housing for refugees was transformed into a recreational park. A prospective, nonrandomized study design used the System of Observing Play and Recreation in Communities (SOPARC) to document the number and activity levels of park users over time, and to compare trends pre- and post-construction. T-tests or tests of medians (when appropriate) were used to compare pre- and post- construction changes in use of non-park and park zones for physical activity and changes in park use by age and gender. Pre- and post-comparisons of people observed using non-park zones (i.e., adjacent streets, alleys and parking lots) and park zones indicated a 38% decrease in energy expended in non- park zones and a 3-fold increase in energy expended within the park (P = 0.002). The majority of park users pre- and post-construction were children, however the proportion of adolescent males observed in vigorous activity increased from 11% to 38% (P = 0.007). Adolescent females and elderly continued to be under-represented in the park. Our findings support an association between creation of accessible outdoor spaces for recreation and improvements in physical activity. Community involvement in park design assured that features included in the park space matched the needs and desires ofthe communities served. Some demographic groups were still under-represented within the park, suggesting a need to develop targeted outreach strategies and programming.

  • Drainage Pierces ANWR in Alaska Study Scenario

    Haley, Sharman; Tussing, Arlon R. (1999)
    A hypothetical scenario of petroleum industry activities adjacent to the 1002 Area of the Arctic National Wildlife Refuge (ANWR) suggests that development from leases under State of Alaska jurisdiction could drain reservoirs that extend under ANWR. Anticipation of such drainage might in turn trigger Congressional authorization for limited surface development of trans-boundary fields. This article provides an overview of 5 scenarios developed for an interdisciplinary study of community sustainability in the Arctic. Forty year scenarios are not offered as predictions, but as "science fiction" - stories combining the best available scientific information and a set of fictional but plausible assumptions to explore implication of a range of plausible outcomes. The final scenario hinges on assumptions about continuing trends in technology that reduce future development costs and surface impacts.

  • Ocean Acidification Risk Assessment for Alaska's Fishery Sector

    Cross, Jessica; Evans, Wiley; Hauri, Claudine; Hurst, T.P.; Ekstrom, Julia; Colt, Steve; Lucey, Noelle; Cooley, Sarah; Mathis, Jeremy; Feely, Richard (Elsevier, 2015)
    The highly productive fisheries of Alaska are located in seas projected to experience strong global change, including rapid transitions in temperature and ocean acidification-driven changes in pH and other chemical parameters. Many of the marine organisms that are most intensely affected by ocean acidification(OA) contribute substantially to the state’s commercial fisheries and traditional subsistence way of life. Prior studies of OA’s potential impacts on human communities have focused only on possible direct economic losses from specific scenarios of human dependence on commercial harvests and damages to marine species. However, other economic and social impacts, such as changes in food security or livelihoods, are also likely to result from climate change. This study evaluates patterns of dependence on marine resources within Alaska that could be negatively impacted by OA and current community characteristics to assess the potential risk to the fishery sector from OA. Here, we used a risk assessment framework based on one developed by the Intergovernmental Panel on Climate Change to analyze earth-system global ocean model hindcasts and projections of ocean chemistry, fisheries harvest data, and demographic information. The fisheries examined were: shellfish, salmon and other fin fish. The final index incorporates all of these data to compare overall risk among Alaska’s federally designated census areas. The analysis showed that regions in southeast and southwest Alaska that are highly reliant on fishery harvests and have relatively lower incomes and employment alternatives likely face the highest risk from OA.Although this study is an intermediate step toward our full understanding, the results presented here show that OA merits consideration in policy planning, as it may represent another challenge to Alaskan communities, some of which are already under acute socio-economic strains.
  • Applying the food–energy–water nexus concept at the local scale

    2021-05-13
    The food–energy–water (FEW) nexus describes interactions among domains that yield gains or trade-offs when analysed together rather than independently. In a project about renewable energy in rural Alaska communities, we applied this concept to examine the implications for sustainability and resilience. The FEW nexus provided a useful framework for identifying the cross-domain benefits of renewable energy, including gains in FEW security. However, other factors such as transportation and governance also play a major role in determining FEW security outcomes in rural Alaska. Here, we show the implications of our findings for theory and practice. The precise configurations of and relationships among FEW nexus components vary by place and time, and the range of factors involved further complicates the ability to develop a functional, systematic FEW model. Instead, we suggest how the FEW nexus may be applied conceptually to identify and understand cross-domain interactions that contribute to long-term sustainability and resilience.
  • Emerging Anthropogenic Influences on the Southcentral Alaska Temperature and Precipitation Extremes and Related Fires in 2019

    Berman, Matthew; Schmidt, Jennifer; Bhatt, Uma S.; Lader, Rick T.; Walsh, John E.; Bieniek, Peter A.; Thoman, Richard L.; Borries-Strigle, Cecilia; Bulock, Kristi; Chriest, Jonathan; et al. (MDPI, 2021-01-17)
    The late-season extreme fire activity in Southcentral Alaska during 2019 was highly unusual and consequential. Firefighting operations had to be extended by a month in 2019 due to the extreme conditions of hot summer temperature and prolonged drought. The ongoing fires created poor air quality in the region containing most of Alaska’s population, leading to substantial impacts to public health. Suppression costs totaled over $70 million for Southcentral Alaska. This study’s main goals are to place the 2019 season into historical context, provide an attribution analysis, and assess future changes in wildfire risk in the region. The primary tools are meteorological observations and climate model simulations from the NCAR CESM Large Ensemble (LENS). The 2019 fire season in Southcentral Alaska included the hottest and driest June–August season over the 1979–2019 period. The LENS simulation analysis suggests that the anthropogenic signal of increased fire risk had not yet emerged in 2019 because of the CESM’s internal variability, but that the anthropogenic signal will emerge by the 2040–2080 period. The effect of warming temperatures dominates the effect of enhanced precipitation in the trend towards increased fire risk.
  • Stoking the flame: Subsistence and wood energy in rural Alaska, United States

    Schmidt, Jennifer I.; Byrd, Amanda; Curl, Jennifer; Brinkman, Todd J.; Heeringa, Krista (Elsevier BV, 2021-01)
    Energy costs are large and increasing in rural Alaska communities, so communities are turning to renewable energy. While, many of these communities have a mixed subsistence-cash economy, the relationship between renewable energy and subsistence has not been studied. Tanana, Alaska has a biomass program and we conducted interviews with 61 households in 2017 to understand how residents perceive the program and its association with subsistence activities. We analyzed Alaska Department of Fish & Game subsistence surveys from 89 communities to estimate differences in subsistence harvest between households that harvest wood and those that do not. Interviews indicated that people who harvest wood for the biomass program were six times more likely to engage in subsistence. Subsistence harvests were nearly double (184 kg/per capita) in households that harvested wood for personal use versus those that did not (101 kg/per capita). Equipment used for both activities was similar, and 57% respondents combined wood harvesting with other activities (e.g. subsistence, travel, etc.). Higher household incomes and employment were positively associated with subsistence participation (p < 0.001) while only household incomes was positively associated with wood harvest through the biomass program (p < 0.001). Overall, the program was perceived as having a positive effect (69%) for the community because it has created jobs (36%), saved people money (23%), promoted sharing (16%), and reduced fuel use by the community (15%). Our research shows that biomass programs have the potential to complement subsistence activities and enhance the sustainability of communities in rural Alaska that are faced with high energy costs.
  • Measuring Progress toward Urban Sustainability: Do Global Measures Work for Arctic Cities?

    Berman, Matthew; Orttung, Robert W. (MDPI AG, 2020-05-03)
    The International Organization for Standardization recently responded to a growing global interest in cities by developing an index for measuring urban sustainability (ISO 37120). We address how well this standard applies to Arctic cities, and potential modifications that might improve its performance. After briefly discussing the goals of sustainability indicators, we examine the extent to which Arctic cities’ remote location, cold and changing climate, and thin, largely resource-based economies may create different sustainability challenges. We then critically examine the content of ISO 37120 and the context in which it was created. We place the index within a broader discussion of urban sustainability indicators and examine the extent to which it really addresses sustainability. We then analyze how well the ISO 37120 accounts for the characteristic features of Arctic cities that produce unique sustainability challenges. Our findings show that only half of ISO 37120′s 128 indicators actually measure future-oriented concerns. We suggest that, while the ISO 37120 may be a useful starting point in quantifying Arctic urban sustainability, the index should only be used as a foundation for a more in-depth analysis. To better represent Arctic cities, the ISO 37120 would need to include indicators that situate cities within their regional contexts, addressing both remoteness and the underlying basis of the Arctic city economy. The index should also measure the role of Indigenous populations, and chart the extent to which cities are working to increase levels of sustainability.
  • Mediating Students’ Fixation with Grades in an Inquiry-Based Undergraduate Biology Course

    DeFeo, Dayna Jean; Tran, Trang C.; Gerken, Sarah (Springer Science and Business Media LLC, 2020-09-29)
    The paper analyzes focus group data to explore student perceptions of an inquiry-based undergraduate biology course. Though the course was designed to mimic the scientific process by incorporating uncertainty, peer review, and self-reflection, students came to class focused on getting As and with a developed schema for didactic instruction and passive learning. They perceived the autonomy and self-directedness of the learning experience as a threat to their grades, and responded with strategies that protected their grades and ego, but were deleterious to learning. Students could identify merits of the inquiry-based approach; however, they made clear: they prioritized grades, and were unwilling to trust an unfamiliar pedagogy if they perceived it jeopardized their grades. In the framework of self-regulated learning, the discussion considers how to scaffold students to foreground learning over achievement.
  • The Effect of a Paired Lab on Course Completion and Grades in Nonmajors Introductory Biology

    DeFeo, Dayna Jean; Bibler, Andrew; Gerken, Sarah (American Society for Cell Biology (ASCB), 2020-08-21)
    This paper explores the effect of a paired lab course on students’ course outcomes in nonmajors introductory biology at the University of Alaska Anchorage. We compare course completion and final grades for 10,793 students (3736 who simultaneously enrolled in the lab and 7057 who did not). Unconditionally, students who self-select into the lab are more likely to complete the course and to earn a higher grade than students who do not. However, when we condition on observable course, academic, and demographic characteristics, we find much of this difference in student performance outcomes is attributable to selection bias, rather than an effect of the lab itself. The data and discussion challenge the misconception that labs serve as recitations for lecture content, noting that the learning objectives of science labs should be more clearly articulated and assessed independent of lecture course outcomes. This paper explores the effect of a paired lab course on students’ course outcomes in introductory biology for nonmajors at the University of Alaska Anchorage (UAA), a large, open-enrollment, 4-year university. We compare outcomes for 10,793 students, 3736 who simultaneously enrolled in the lab and 7057 who did not, and analyze the degree to which they select into the lab on observable characteristics to explore the following research questions: 1. Are students who take a paired lab more likely to complete the lecture component (i.e., receive a final grade as opposed to withdrawing or receiving an Incomplete)? 2. Are students who take a paired lab more likely to receive a higher grade in the lecture component? 3. Does the laboratory experience differently affect course outcomes for students in specific demographic subgroups (e.g., gender, race, high school urbanicity, age, prior academic performance, and socioeconomic status)?
  • Who Benefits from an Oil Boom? Evidence from a Unique Alaskan Data Set

    James, Alexander; Guettabi, Mouhcine (Elsevier, 2020-08-26)
    Oil booms have been shown to increase local employment and wages. But these effects reflect the aggregated experience of residents, commuters, and recent migrants alike. This paper takes advantage of a unique data set that identifies a rich set of labor market outcomes by place of residence, rather than by place of work. Exploiting this feature of the data, we examine the effect of a major oil boom on employment and wage outcomes in the North Slope Borough of Alaska. This analysis is juxtaposed with a more conventional one that uses place-of-work data collected from the Bureau of Economic Analysis. Using the Synthetic Control Method, we find that the oil boom of the late 2000s significantly increased non-residential employment. While the boom caused residential employment to shift from the public to the private sector, total residential employment was unaffected. There is weak evidence that residential wages increased in response to the boom. These results are important as drilling decisions are often negotiated locally by interest groups that might be less concerned with general equilibrium effects.
  • Exploring the Term “Resilience” in Arctic Health and Well-Being Using a Sharing Circle as a Community-Centered Approach: Insights from a Conference Workshop

    Healey Akearok, Gwen; Cueva, Katie; Stoor, Jon; Larsen, Christina; Rink, Elizabeth; Kanayurak, Nicole; Emelyanova, Anastasia; Hiratsuka, Vanessa (MDPI AG, 2019-02-02)
    In the field of Arctic health, “resilience” is a term and concept used to describe capacity to recover from difficulties. While the term is widely used in Arctic policy contexts, there is debate at the community level on whether “resilience” is an appropriate term to describe the human dimensions of health and wellness in the Arctic. Further, research methods used to investigate resilience have largely been limited to Western science research methodologies, which emphasize empirical quantitative studies and may not mirror the perspective of the Arctic communities under study. To explore conceptions of resilience in Arctic communities, a Sharing Circle was facilitated at the International Congress on Circumpolar Health in 2018. With participants engaging from seven of the eight Arctic countries, participants shared critiques of the term “resilience,” and their perspectives on key components of thriving communities. Upon reflection, this use of a Sharing Circle suggests that it may be a useful tool for deeper investigations into health-related issues affecting Arctic Peoples. The Sharing Circle may serve as a meaningful methodology for engaging communities using resonant research strategies to decolonize concepts of resilience and highlight new dimensions for promoting thriving communities in Arctic populations.
  • A Framework for Culturally Relevant Online Learning: Lessons from Alaska's Tribal Health Workers.

    Cueva, Katie; Cueva, Melany; Revels, Laura; Lanier, Anne P; Dignan, Mark; Viswanath, K; Fung, Teresa T; Geller, Alan C (2019-08)
    Culturally relevant health promotion is an opportunity to reduce health inequities in diseases with modifiable risks, such as cancer. Alaska Native people bear a disproportionate cancer burden, and Alaska's rural tribal health workers consequently requested cancer education accessible online. In response, the Alaska Native Tribal Health Consortium cancer education team sought to create a framework for culturally relevant online learning to inform the creation of distance-delivered cancer education. Guided by the principles of community-based participatory action research and grounded in empowerment theory, the project team conducted a focus group with 10 Alaska Native education experts, 12 culturally diverse key informant interviews, a key stakeholder survey of 62 Alaska Native tribal health workers and their instructors/supervisors, and a literature review on distance-delivered education with Alaska Native or American Indian people. Qualitative findings were analyzed in Atlas.ti, with common themes presented in this article as a framework for culturally relevant online education. This proposed framework includes four principles: collaborative development, interactive content delivery, contextualizing learning, and creating connection. As an Alaskan tribal health worker shared "we're all in this together. All about conversations, relationships. Always learn from you/with you, together what we know and understand from the center of our experience, our ways of knowing, being, caring." The proposed framework has been applied to support cancer education and promote cancer control with Alaska Native people and has motivated health behavior change to reduce cancer risk. This framework may be adaptable to other populations to guide effective and culturally relevant online interventions.

  • Quantifying expert opinion with discrete choice models: Invasive elodea's influence on Alaska salmonids

    Little, Joseph; Hayward, Gregory D. (Elsevier, 2020-10-01)
    Scientific evidence should inform environmental policy, but rapid environmental change brings high ecological uncertainty and associated barriers to the science-management dialogue. Biological invasions of aquatic plants are a worldwide problem with uncertain ecological and economic consequences. We demonstrate that the discrete choice method (DCM) can serve as a structured expert elicitation alternative to quantify expert opinion across a range of possible but uncertain environmental outcomes. DCM is widely applied in the social sciences to better understand and predict human preferences and trade-offs. Here we apply it to Alaska's first submersed invasive aquatic freshwater plant, Elodea spp. (elodea), and its unknown effects on salmonids. While little is known about interactions between elodea and salmonids, ecological research suggests that aquatic plant invasions can have positive and negative, as well as direct and indirect, effects on fish. We use DCM to design hypothetical salmonid habitat scenarios describing elodea's possible effect on critical environmental conditions for salmonids: prey abundance, dissolved oxygen, and vegetation cover. We then observe how experts choose between scenarios that they believe could support persistent salmonid populations in elodea-invaded salmonid habitat. We quantify the relative importance of habitat characteristics that influence expert choice and investigate how experts trade off between habitat characteristics. We take advantage of Bayesian techniques to estimate discrete choice models for individual experts and to simulate expert opinion for specific environmental management situations. We discuss possible applications and advantages of the DCM approach for expert elicitation in the ecological context. We end with methodological questions for future research.
