Mom Power (MP) is a trauma-informed parenting intervention which aims to break the cycle of intergenerational risk transmission by promoting enhanced parent-child attachment, increased social support, connection to community services, and utilization of self-care skills. MP was developed to engage vulnerable families (e.g., mothers with trauma histories, low income, single mothers) and seeks to mitigate common treatment accessibility barriers for underserved populations through provision of childcare, transportation, and a trauma-informed/culturally sensitive milieu. Results from a community-based randomized control trial (RCT) in Michigan (MI) have shown that MP is effective at reducing maternal psychopathology, lowering parenting stress, decreasing parental hopelessness, and promoting reflective parenting; however, no studies have examined the feasibility of implementing MP outside of MI, nor the effectiveness of MP with additional samples (Rosenblum et al., 2017). The present study is a hybrid implementation/effectiveness design that is two-fold: (1) Implementation design to assess the feasibility of training rural, Appalachian community-based providers in the MP model, recruiting high risk mothers, retaining mothers in this 10-week intervention, and implementing MP groups with community-based partners (2) An effectiveness oriented, pre-post, within subjects design with mothers of young children who are attending MP groups in the community [n = 33 mothers; M maternal age = 26 (SD = 5) years; M child age = 12 months (SD = 15)]. Regarding implementation results, the MP training involved n = 31 community-based providers from 5 agencies (e.g., community mental health, foster care agency) and 3 university-based mental health training programs. In the 18 months since training, three 10-week MP groups have been completed (n = 25 mother-child dyads), and one group is currently being held (n = 8 dyads). Regarding recruitment, we have had great success reaching high risk families, having more family referrals than available group slots. Of the families served in TN thus far, 60% had DCS involvement, 46% were in substance abuse treatment, 68% endorsed ≤ 4 ACEs, 77% had clinically significant depression, 58% had clinically significant anxiety, 78% were single/had no co-parent, 81% had low educational attainment, and 100% were below the federal poverty level. Regarding effectiveness, following completion of the current group, we will present pre-/post- differences in maternal PTSD symptoms, emotion regulation, and parenting behavior, as well as examine the relationship between attendance and change scores.

In 1965, Duke Power announced the construction of a series of dams along the Keowee and Little rivers in Oconee County, South Carolina. The dams would create water reservoirs for one of the largest hydro-electric and nuclear power facilities in the nation. The dominant narrative focuses on the recreational activities, power generation, and economic development facilitated by the creation of lakes Jocassee and Keowee. However, residents of the Keowee and Jocassee valleys had to be removed, a process that started years earlier when Duke Power began serious land purchasing efforts. This study focused on discovering diverse narratives from people that were displaced or otherwise affected by the lakes. In doing so, made comparisons with other projects on displaced populations in Appalachia, examined the beneficiaries of the project, the treatment of locals, and how Duke Power and local government presented the project through local media.

Lower Pennsylvanian, coal-bearing, siliciclastic strata of the central Appalachian foreland basin were deposited in continental to marginal marine environments influenced by high-amplitude relative sea level fluctuations. Sediment was derived from both the low-grade metamorphic terrain of the emergent Alleghanian orogen towards the southeast, and the cratonic Archean Superior Province in the north. Immature sediments derived proximally from the Alleghanian orogen, including sublithic sandstone bodies, were deposited as a southeasterly-thickening clastic wedge within a southeast-northwest oriented transverse drainage system. Texturally and mineralogically mature quartzarenites were deposited in strike-parallel elongate belts along the western periphery of the basin. These mature quartzarenites are braided fluvial in origin and were deposited within northeast-southwest oriented axial drainage head-watered in a northerly cratonic source area. The contemporaneity of transverse and axial fluvial systems defines a trunk--tributary drainage system operating in the central Appalachian foreland basin during the early Pennsylvanian. Detailed analysis of core, gamma ray logs, and cross-sections reveals a hierarchy of bounding discontinuities and architectural elements within the study interval. Discontinuities are both erosional and depositional (condensed) surfaces of interpreted 3rd-order (~ 2.5 Ma) and 4th-order (~ 400 k.y.) origin. Architectural elements within 4th-order sequences consist of upward-fining lowstand and transgressive incised valley fill, alluvial, and estuarine deposits, and upward-coarsening highstand deltaic deposits that are separated by condensed sections. 4th-order sequences are stacked into 3rd-order composite sequences. Sequence stratigraphic architecture in the central Appalachian basin can therefore be attributed to 4th-order Milankovitch orbital eccentricity cycles superimposed on 3rd-order orogenically driven subsidence, or more likely, 4th-order Milankovitch orbital eccentricity cycles superimposed on a lower-frequency eccentricity cycle. The widespread nature of both 3rd- and 4th-order marine flooding zones and sequence boundaries enables both genetic and depositional sequence stratigraphy to be applied to terrigenous to marginal marine coal-bearing strata of the central Appalachian basin. Regionally extensive coal beds occur in close association with both 4th-order condensed sections as well as within highstand deltaic deposits. Formation of coal beds in the central Appalachian basin of southwest Virginia is therefore attributed to both an allocyclic glacio-eustatic mechanism, associated with Milankovitch orbital eccentricity cycles, and autocyclic deltaic processes related to channel avulsion and delta lobe switching. / Master of Science

The lower Pennsylvanian, coal-bearing, siliciclastic strata in Dickenson/Wise counties of southwest Virginia were deposited in continental to marginal marine environments influenced by high-amplitude relative sea level fluctuations. Coal-bearing siliciclastics of the eastern facies belt are fluvio-deltaic in origin, with sediment derived from the erosion of low-grade metamorphic and Grenvillian-Avalonian terranes of the Alleghanian orogen to the southeast. Elongate NNE trending quartzarenite belts in the northwestern region of the basin are braided-fluvial deposits and were sourced by the cratonic Archean Superior Province to the north. This orthogonal relationship between the southeastern coal-bearing siliciclastics and the northwestern quartzarenites reflect a trunk-tributary drainage system operating during the lower Pennsylvanian in the central Appalachian basin. Analysis of core, gamma ray and density logs, and six cross-sections within an approximately 20 km² study area reveals a hierarchy of bounding discontinuities and architectural elements. Discontinuities are both erosional (unconformable) and depositional (condensed) and are 3rd-order (~ 2.5 Ma) and 4th-order (~ 400 k.y.) in origin. Architectural elements are bound by 4th-order discontinuities and consist of upward-fining lowstand and transgressive incised valley fill, alluvial, and estuarine deposits, and upward-coarsening highstand deltaic deposits and represent 4th-order sequences. Lowstand and transgressive deposits are separated from the highstand deposits by marine flooding zones (condensed sections). 4th-order sequences are stacked into composite 3rd-order sequences. Sequence development can be attributed to 4th-order Milankovitch orbital eccentricity cycles superimposed on a lower-frequency eccentricity cycle. Extensive coals occur in both transgressive and highstand systems tracts. Coals within the transgressive systems tract are associated with 4th-order flooding surfaces, while coals within the highstand systems tract occur within high-frequency deltaic autocycles. Therefore, coals formation in the central Appalachian basin can be attributed to be of both allocyclic (glacio-eustacy) and autocyclic (deltaic processes) mechanisms. / Master of Science

Quaternary magnetic studies have provided the conceptual framework to bridge magnetic studies into ancient systems. In cases where environmental materials have been subjected to diagenetic alteration two questions come to mind: 1) What part of the magnetic signal is preserved in the rocks; and 2) can the preserved signal be used to infer/identify magnetic patterns that are characteristic of the depositional, post-depositional, and/or diagenetic environment. Analyses of multi-parameter magnetic experiments conducted on upper Mississippian and lower Pennsylvanian continental successions reveal that distinct depositional, pedogenic, and diagenetic magnetic patterns can be separated and identified. Evidence for a primary depositional signal in several of the upper Mississippian lithofacies is identified by a detrital remanence component attributed to source-area-derived magnetite/titanomagnetite. Red and gray vertisols preserve a Mississippian pedogenic signal characterized by magnetic enrichment, depletion, and amalgamation patterns that are associated with the removal and transport of Fe-rich clays as well as vertical mixing by shrink-swell mechanisms. These well-developed vertisols are interpreted to reflect significant hiatuses in sedimentation associated with prolonged exposure on interfluve/floodplain surfaces that may correlative with incised valleys (lowstand surface of erosion). Similarly, in lower Pennsylvanian quartz arenite facies, early siderite cementation zones as well as conglomerate lags with distinctive magnetic characteristics are thought to reflect periods of prolonged exposure and to define unconformities within compound valley fills. / Master of Science
