The purpose of this mixed methods study was to examine the sense of belonging of state college transfer students who enroll at a large research-intensive university through structured and unstructured transfer pathways using the Sense of Belonging Instrument (SBI; Hoffman, Richmond, Morrow, (&) Solomon, 2002). The SBI includes five subscales (Peer Support, Faculty Support, Classroom Comfort, Isolation, and Empathetic Faculty Understanding). To date, no systematic investigation has considered...
Show moreThe purpose of this mixed methods study was to examine the sense of belonging of state college transfer students who enroll at a large research-intensive university through structured and unstructured transfer pathways using the Sense of Belonging Instrument (SBI; Hoffman, Richmond, Morrow, (&) Solomon, 2002). The SBI includes five subscales (Peer Support, Faculty Support, Classroom Comfort, Isolation, and Empathetic Faculty Understanding). To date, no systematic investigation has considered the construct of belonging with this population or transfer pathway. The findings from this study (n = 54) found a positive statistically significant correlation between Peer Support and Isolation (r(52) =.801, p = .000) and a statistically significant difference between the mean values of Empathetic Faculty Understanding between the structured and unstructured pathways (p = 0.027). This study showed that structured transfer pathway student sense of belonging was grounded in the classroom experience, empathetic faculty, and faculty support. Unstructured transfer pathway student sense of belonging was grounded in peer relationships, the classroom experience, and empathetic faculty. First generation participants were more likely to perceive isolation than non-first generation participants and structured pathway participants were more likely to perceive faculty empathetic understanding than unstructured pathway participants. There were also differences in the qualitative data between the pathway groups, including differing perceptions of faculty care and empathy, peer engagement, and the role of Advisors and online support systems in the transfer experience. The data and findings presented in this study show that the academic experience in the classroom and the perception of empathetic faculty are central to state college transfer student experience and contributes to transfer student sense of belonging.

Extreme operating temperatures within the turbine section of jet engines require sophisticated methods of cooling and material protection. Thermal barrier coatings (TBCs) achieve this through a ceramic coating applied to a substrate material (nickel-based superalloy). Electron-beam physical vapor deposition (EB-PVD) is the industry standard coating used on jet engines.

Show moreExtreme operating temperatures within the turbine section of jet engines require sophisticated methods of cooling and material protection. Thermal barrier coatings (TBCs) achieve this through a ceramic coating applied to a substrate material (nickel-based superalloy). Electron-beam physical vapor deposition (EB-PVD) is the industry standard coating used on jet engines. By tailoring the microstructure of an emerging deposition method, Plasma-spray physical vapor deposition (PS-PVD), similar microstructures to that of EB-PVD coatings can be fabricated, allowing the benefits of strain tolerance to be obtained while improving coating deposition times. This work investigates the strain through depth of uncycled and cycled samples using these coating techniques with synchrotron X-ray diffraction (XRD). In the TGO, room temperature XRD measurements indicated samples of both deposition methods showed similar in-plane compressive stresses after 300 and 600 thermal cycles. In-situ XRD measurements indicated similar high-temperature in-plane and out-of-plane stress in the TGO and no spallation after 600 thermal cycles for both coatings. Tensile in-plane residual stresses were found in the YSZ uncycled PS-PVD samples, similar to APS coatings. PS-PVD samples showed in most cases, higher compressive residual in-plane stress at the YSZ/TGO interface. These results provide valuable insight for optimizing the PS-PVD processing parameters to obtain strain compliance similar to that of EB-PVD. Additionally, external cooling methods used for thermal management in jet engine turbines were investigated. In this work, an additively manufactured lattice structure providing transpiration cooling holes is designed and residual strains are measured within an AM transpiration cooling sample using XRD. Strains within the lattice structure were found to have greater variation than that of the AM solid wall. These results provide valuable insight into the viability of implementing an AM lattice structure in turbine blades for the use of transpiration cooling.
