Erosion poses a significant threat to oceanic beaches worldwide. To combat this threat, management agencies often utilize renourishment, which supplements eroded beaches with offsite sand. This process can alter the physical characteristics of the beach and can influence the presence and abundance of microbial communities. In this study, we examined how an oceanic beach renourishment project may have impacted the presence and abundance of Escherichia coli ( E . coli ), a common bacteria species, and sand grain size, a sediment characteristic that can influence bacterial persistence. Using an observational field approach, we quantified the presence and abundance of E . coli in sand (from sub-tidal, intertidal, and dune zones on the beach) and water samples at study sites in both renourished and non-renourished sections of Folly Beach, South Carolina, USA in 2014 and 2015. In addition, we also measured how renourishment may have impacted sand grain size by quantifying the relative frequency of grain sizes (from sub-tidal, intertidal, and dune zones on the beach) at both renourished and non-renourished sites. Using this approach, we found that E . coli was present in sand samples in all zones of the beach and at each of our study sites in both years of sampling but never in water samples. Additionally, we found that in comparison to non-renourished sections, renourished sites had significantly higher abundances of E . coli and coarser sand grains in the intertidal zone, which is where renourished sand is typically placed. However, these differences were only present in 2014 and were not detected when we resampled the study sites in 2015. Collectively, our findings show that E . coli can be commonly found in this sandy beach microbial community. In addition, our results suggest that renourishment has the potential to alter both the physical structure of the beach and the microbial community but that these impacts may be short-lived.

Since time immemorial Alaska Natives (AN) lived and aged well, yet today they experience high rates of illness and lower access to care because of colonisation. Aand this research explores successful ageing from an AN perspective or what it means to achieve \"Eldership\" in the rural Northwest Alaska. A community-based participatory research approach was used to engage participants at every stage of the research process. Semi-structured interviews were conducted with 16 AN men and 25 women and the interviews were professionally transcribed. Kleinman's explanatory model served as the foundation of the questionnaire to gain a sense of the beliefs about ageing and guide the thematic analysis to establish an AN understanding of successful ageing. The foundation of the Norton Sound southern sub-region Model of Successful Ageing is the reciprocal relationship between Elders and family which enables Elders to access meaningful activities, including Native ways of life, physical health, spirituality, and emotional well-being. Community-based interventions should foster opportunities for Elders to share their Native way of life alongside family and community members, which will enable them to remain physically active, maintain healthy emotional well-being, continue engaging in spiritual practices, and contribute to the health and well-being of families.

The population of the United States is aging and by 2045 it is projected that approximately 1 in every 6 Alaskans will be 65+. Delivering healthcare and meeting the needs of older Alaskans in their community is critical to supporting healthy aging and community sustainability. Alaska Native (AN) Elders are underserved with very few studies providing an emic perspective on their experience aging. This research opens the door and allows us a glimpse of the AN Elder experience of aging: the values, beliefs, and behaviors that allow them to age well. This study highlights the characteristics and activities of AN Elders in the Aleutian and Pribilof Islands to further develop the model of AN successful aging. There are many theories of aging and this study explores a cross-cultural understanding of gerotranscendence - the personal and interpersonal changes that result from successful aging or achieving Eldership. This study interviewed Elders in two communities of the Aleutian and Pribilof Islands region. Using 22 standardized questions based on the explanatory model, researchers facilitated discussion of what it means to be an Elder and age successfully. Employing thematic analysis, interview transcripts were analyzed for themes to organize the data. Themes were organized into 5 core elements of successful aging with specific emphasis on values, beliefs, and behaviors that were protective and helped them adapt to aging-related changes. Interview content, meaning, and themes support the four elements of the AN model of successful aging developed by Lewis (The Gerontologist, 51(4), 540-549, 2011): Mental and Emotional Wellbeing, Spirituality, Purposefulness and Engagement, and Physical Health. Elders’ stories highlight the importance of reflection, personal growth, and psychosocial development. Elders who more strongly identified with their role in the community described how their perspective had changed and they shared stories that emphasized culture, connection to the land, and enjoyment of daily activities that resulted in increased life satisfaction. Elders provided clear evidence that they experienced aspects of gerotranscendence, which Tornstam (Journal of Aging Studies, 11(2), 143-154, 1997) categorized as the cosmic dimension, the self, and social and personal relationships. Elders adapting to aging-related changes and embracing their role as an Elder provided the greatest evidence of gerotranscendence - they developed new perspectives on life, took on new roles within the community, and experienced a shift in mindset that reinforced the importance of culture, tradition, and the Native Way of Life. This research allowed AN Elders to share their experiences, define successful aging, and expand the concept of Eldership to include changes in mindset, values, and relationships with themselves and others. The study is a framework to help us better understand the experiences of AN Elders aging successfully and the wisdom they wish to impart to others to help them learn to live healthy and meaningful lives.

This article builds on the People Awakening (PA) Project, which explored an Alaska Native (AN) understanding of the recovery process from alcohol use disorder and sobriety. The aim of this study is to explore motivating and maintenance factors for sobriety among older AN adult participants (age 50+) from across Alaska. Ten life history narratives of Alaska Native older adults, representing Alutiiq, Athabascan, Tlingit, Yup’ik/Cup’ik Eskimos, from the PA sample were explored using thematic analysis. AN older adults are motivated to abstain from, or to quit drinking alcohol through spirituality, family influence, role socialization and others’ role modeling, and a desire to engage in indigenous cultural generative activities with their family and community. A desire to pass on their accumulated wisdom to a younger generation through engagement and sharing of culturally grounded activities and values, or indigenous cultural generativity, is a central unifying motivational and maintenance factor for sobriety. The implications of this research indicates that family, role expectations and socialization, desire for community and culture engagement, and spirituality are central features to both AN Elders’ understanding of sobriety, and more broadly, to their successful aging. Future research is needed to test these findings in population-based studies and to explore incorporation of these findings into alcohol treatment programs to support older AN adults’ desire to quit drinking and attain long-term sobriety. Sobriety can put older AN adults on a pathway to successful aging, in positions to serve as role models for their family and community, where they are provided opportunities to engage in meaningful indigenous cultural generative acts.

Alcohol research in Alaska has shifted to strengths-based approaches-it will be important to learn what motivates older adults to maintain recovery rather than to relapse. Alaska Native older adults have a desire to pass on their accumulated wisdom to a younger generation through engagement and sharing of cultural activities and values, which could help to motivate and maintain sobriety. Using motivational interviewing with older adults can explore cultural motivations that support older Alaska Native adults' desire to quit drinking, maintain recovery, and incorporate them into relapse prevention activities.

Successful aging in rural Alaska communities has been established as a characteristic best described by reaching “Eldership,” conveying reverence and respect from the community and implying leadership responsibilities. Most Alaska Native (AN) Elders believe that aging successfully or aging well happens within their home communities. However, limited rural resources lead Elders to relocate to urban settings. While protective factors supporting aging well in rural communities have been established, little is known about which factors support aging well after relocation to an urban setting. This exploratory, qualitative, community-based participatory research study explored AN Elder’s (ages 48–84) experiences comparing successful aging within four rural Alaska communities and of Elders who relocated from a rural to an urban community. Thirteen rural-based Elders and 12 urban-based Elders semi-structured interviews were compared to explore how successful aging was experienced similarly and differently in rural and urban settings. To age well in urban Alaska, access to health care services, family, and community engagement were essential. The main challenges for urban Elders involved establishing a sense of community, intergenerational involvement, and the ability to continue traditional ways of living. This research identified challenges, similarities, and differences in aging well in an urban community. The findings of this study inform practices, services, and policies to improve existing urban services and initiate needed urban services to foster successful aging after relocation from remote rural areas into urban communities in Alaska.
