This qualitative study examined the changes that have occurred due to global and hemispheric market forces, and particularly through Hispanic immigration, in a small town in Southwest Virginia. The interdisciplinary study is written as a narrative, and includes descriptions of the town and people of Galax, Virginia and of the predominately Mexican immigrants who have come to live there. The primary focus is on the changes and challenges that occur in schools from the perspective of teachers and administrators, as well as from the students. Local residents and Hispanic immigrants alike share their perspectives on the impacts of immigration and their efforts to accommodate changes in their lives and communities. The researcher draws from his personal experience as an immigrant to Mexico to probe the search for identity and meaning that are common to immigrants. The study found that Hispanic children have devised an unofficial dual-language peer support system for learning in the classrooms that circumvents the assimilationist approach to which the schools have adhered. Immigrant children experience marginalization even in caring school environments such as those found in the Galax schools, due largely to the lack of preparation of teachers and administrators in culturally appropriate pedagogy. The study calls for more direct involvement between the university and local communities experiencing significant change due to global forces. Demographic change through immigration impacts schools implicitly, and requires the support and education of teachers and administrators through regional schools of education. / Ph. D.

This study explores how students in rural areas of Tennessee's Cumberland Plateau area perceive engineering as a future career. This area is a portion of the greater Appalachian region, which has historically, faced disproportionate economic struggles when compared to other areas of the United States. However, little research on career choice exists outside of the coal producing areas of Central Appalachia. This research, in contrast, focuses on rural counties without interstate access, situated along the Cumberland Plateau in Tennessee, an area with an economy historically based in manufacturing. This research focuses on understanding students' perceptions of engineering as a future career and on factors that support and inhibit the development of these perceptions. To understand these perceptions, the study used qualitative, semi-structured interviews, situated in a Social Constructivist worldview, informed by the Future Possible Selves framework. Participants include 27 high school students, 7 college engineering students, and 5 college students who had exposure to engineering through a formal program but are currently enrolled in another major. Results of the study show that without access to formal programs or professionals to expose them to engineering, participants did not have a clear perception of engineering, and were not likely to pursue this career. Exposure through a formal program seemed to spark the start of engineering future possible self development by aligning engineering with activities participants enjoy. However, these participants often also believed that they lacked some key "ability" needed to become an engineer. Participants who had access to both formal programs and professionals were able to provide a clear description of potential engineering careers, aligning such careers with activities they enjoyed and, importantly, with desired attributes of their future. In addition, participants typically described relationships with professionals as mitigating the fear that an engineering career was beyond their "ability." These results provide evidence, that in this study area, printed materials and programs are not enough; people clearly make the difference in helping students develop a clear perception of engineering as a viable future career choice. This result has multiple implications for engineering educators and industries interested in K-12 outreach. / Ph. D.

With people living longer and coming into old age with more diverse relational experiences than previous cohorts (e.g., divorce, cohabitation), researchers anticipate that the so-called baby boomers will be more interested in pursuing romantic relationships in later life than their predecessors. On the other hand, we know that the experience of aging varies among people on the basis of their social locations (e.g., racial, gender, class). As central Appalachia is a place characterized by persistent poverty, I interviewed single, midlife White women from a community in West Virginia (N=11) to investigate (a) their experiences with family life and (b) their expectations for romantic relationships in later life. I used grounded theory methodology to develop a theory of intimacy and family life in central Appalachia. I found that the women who were more integrated into their families of origin had little or no interest in romantic relationships, regardless of their past relationship history. Women who perceived their childhoods as traumatic were less integrated into their families of origin and had a weaker sense of place, but had more interest in finding a romantic partner in later life. I concluded for those with a strong sense of place the importance of the family of origin persisted through midlife and into old age. / Ph. D.

In order to ensure clean drinking water for all, it is crucial to understand potential upland stressors that compromise the quality of source waters treated by local community water systems (CWSs). Contamination associated with specific types of land cover can result in downstream water quality degradation, which may reduce the effectiveness of treatment by CWSs. Surface mining has been hypothesized as a source of drinking water degradation within the Central Appalachian region, which may result in adverse exposures and health disparities. The purpose of this study was to identify potential correlations between land cover and adverse birth outcomes (ABOs) through the application of watershed epidemiology, an emerging environmental health paradigm. Birth records for the Central Appalachian region were acquired from their respective state health departments from 2001 to 2015: each record contained the mother's street address, outcome variables, and covariates. Records were included in later analyses if they fell within an approximated CWS service area. Contributing land cover to each CWS was determined via previously delineated watersheds that relied on CWS intake points. A binomial generalized linear model was used to compare low birth weight (LBW), term low birth rate (tLBW), and preterm birth (PTB) incidence to CWS source watershed land cover, Safe Drinking Water Act (SDWA) violations, CWS size, and covariates related to the birth records. Source watershed mining and SDWA health based (HB) violations were significantly associated with greater risks for preterm birth (PTB) and low birth weight (LBW). Future work should be conducted to explore upstream flow impacts, address missing data in the birth records, and to more accurately represent CWS service areas to better characterize exposure. / Master of Science / Millions of individuals throughout the world are sickened by waterborne exposures every year. To ensure clean drinking water long-term, it is crucial to understand how human land cover might change the water quality of source watersheds, as this may impact the effectiveness of water treatment and increase adverse human health exposures. The goal of this effort is to understand whether land cover is linked to downstream adverse birth outcomes (ABOs) in Central Appalachia, a region of the United States previously associated with high disease incidence suspected to be partially linked to environmental exposure. Birth records were acquired for the years of 2001 to 2015 from four (VA, WV, TN, KY) respective state health departments. Each record contained the mother's address, outcome variables, and covariates (e.g., race, ethnicity). Births were located within approximate service areas for 140 surface water dependent community water systems (CWS) within the region. Data from each CWS, including weighted land cover proportions for their source watershed, were merged with the birth records according to approximate service areas. Statistical analysis suggested that higher source watershed levels of mining and urban development were associated with higher risks of preterm birth (PTB) and low birth weight (LBW). The number of health based (HB) violations associated with each CWS was also associated with both of these outcomes. Major limitations of this work include birth record data gaps and the lack of publicly available CWS service areas and/or water consumption rates, which does increase the risk of exposure misclassification.

The purpose of this study was to conduct a qualitative exploration of the relationship between Appalachian identity and the college experience among Giles High School graduates who attend Virginia Tech. The population for this study was Giles High School graduates who attend Virginia Tech. The sample size included ten volunteers who graduated from Giles High School in Pearisburg, Virginia, and have attended Virginia Tech in the past three years. Data collection was obtained from the sample by conducting semi-structured interviews. Coding occurred in two phases using thematic coding. The first phase consisted of an initial coding to establish an understanding of the responses and develop codes to fit the responses for analysis. The second phase of coding consolidated, re-affirmed, compared, and contrasted categories created in the first phase using matrices. The results revealed that the interviewees did communicate an Appalachian identity. When describing Appalachia, the interviewees communicated both positive and negative perceptions of their hometown. Attending college did result in a change in their Appalachian identity. Common changes were in their willingness to accept people different from themselves, their perceptions of Giles County in comparison to more diverse and urban areas, and their appreciation for the natural beauty of Giles. Compared to previous research, I found that Giles High School students seem to have less of a disrupting experience when attending college; however, dominant cultural messages still influence the identity of Appalachian students. Further research should be conducted to confirm the results and analysis. / Master of Science

Thousands of communities across the nation are exposed to health risks from contaminated drinking water. Upstream anthropogenic land covers have been linked with the degradation of source drinking water quality and likely pose a threat to a community water system's (CWS's) ability to provide safe drinking water. The goal of this study was to predict the differences in compliance with the Safe Drinking Water Act (SDWA) between CWSs based on their upstream land cover, economic situation, and system characteristics. In Central Appalachia, from 2001 to 2016, proportions of land cover in each target CWS's upstream source water watershed were weighted based on their distance to a CWS's source water intake. Violations to the SDWA at respective CWSs over the same period were modeled with their distance weighted land cover proportions, economic status of the county served, and system characteristics as covariates. The major findings were that increases in low intensity development increased the likelihood of a health-based violation, larger CWSs were less likely than smaller CWSs to obtain a monitoring and reporting violation, and CWSs that distributed purchased water were the least likely to incur either violation type. These results suggest that communities that have CWSs that are repeatedly failing to remain in compliance with the SDWA may be able to reduce public health risks associated with drinking water by purchasing from a larger CWS. Further to protect public health, community managers should consider source water protection and/or upgrading a CWS's treatment capacity prior to developing a previously undeveloped area. / Master of Science / Millions of people across the nation face health risks from contaminated drinking water. Understanding what factors influence a community water system's ability to supply safe drinking water is critical in the effort to protect public health. Land cover altered by humans has been found to pollute drinking water sources and may be linked to unsafe drinking water. This study aims to predict the differences in compliance with the Safe Drinking Water Act (SDWA) between community water systems (CWSs) based on their upstream land cover, economic situation, and system characteristics. In Central Appalachia, proportions of land cover between 2001 and 2016 were calculated for each target CWS's upstream source water watershed. Violations to the SDWA were used in a statistical analysis with land cover, economic status of the county served, and system characteristics of respective CWSs. The major findings were that increases in low intensity developed area increased the likelihood of health-based (HB) violations, larger CWSs were more likely than smaller CWSs to monitor and report their water quality, and CWSs that served purchased water were the least likely to have a HB or monitoring and reporting violation. These results suggest that purchasing drinking water from a larger CWS may allow water providers to reduce the risk to public health from unsafe drinking water. Additionally, protecting drinking source water and/or upgrading a CWS's treatment ability prior to developing a previously undeveloped area may reduce threats to drinking water safety.
