Relationships of Reform: Frances MacGregor Ingram, Immigrants, and Progressivism in Louisville, Kentucky, 1900-1940Laura Eileen Criss Bergstrom (13144761) 24 July 2022 (has links)
<p>This dissertation focuses on the life of Frances MacGregor Ingram, a progressive reformer in Louisville, Kentucky. It follows Ingram’s career in social work at the Neighborhood House settlement and the Progressive reform movements in which she held leadership positions from 1905 to 1939. This project concentrates on Ingram’s involvement in reform movements pertaining to tenement housing, garbage collection management, dance hall regulation, juvenile delinquency, mental hygiene institutions, probation, wholesome recreation, child welfare, child labor, women’s working conditions, unemployment, and Great Depression relief.</p>

<p>Most Progressive Era scholarship concentrates on northern cities and reformers, such as Jane Addams at Hull House. But much of the literature overlooks southern contributions to the settlement house movement and progressive reform as a whole. This dissertation serves three purposes. First it helps fill the gap in scholarship on southern progressivism. Reformers in the urban South were not limited to charity work and prohibition. They engaged in complex and dynamic social reforms. Incredibly diverse in scope, Kentucky’s reform history should be understood in the context of southern society and politics, which impacted which progressive reforms were successful and which were not.</p>

<p>Second, it builds on other women’s reform scholars by expanding previous conceptions of the Progressive Era to include the 1930s. By doing so, it provides a better understanding of women’s reform activism. Third, this dissertation provides a more balanced approach by emphasizing the alliances Ingram formed with immigrant communities. With a few exceptions, settlement literature primarily focuses on the movement leaders. Unlike some settlements, Neighborhood House Americanization programs via clubs, recreation, and citizenship classes were negotiated between the settlement and its neighbors. Through the lens of Ingram’s urban reform experience in Kentucky, this dissertation uses gender, class, race, ethnicity, and region to unpack the complicated relationships between reformers like Ingram, working-class immigrants, and male political officials. </p>

Promotion & Non-Promotion in the Louisville Elementary SchoolsBelcher, E. W. 01 August 1936 (has links)
To promote or not to promote has long been a question in the minds of both administrators and teachers; however, the segregated problem of promotion and non-promotion did not receive much attention until about fifteen years ago. In the past decade and a half much time and careful, thoughtful study have been devoted to this problem by leading educators.

Riding Red Ink: Public Ownership of Mass Transit in IndianapolisWilhite, Ryan Daniel January 2011 (has links)
**Note** During the research process, IndyGo donated some of the resources cited within this paper to the Indiana Historical Society. That collection has not been archived yet. Further, IndyGo may have placed other documents (created during the time of public ownership) in the Indiana State Archives or the Indiana State Library. / Indiana University-Purdue University Indianapolis (IUPUI) / Today, most urban mass transit providers are publicly owned. Just a few decades ago, and for a majority of the history of mass transit, private owners provided transportation for communities. The decline of private ownership in Indianapolis resulted in transit crisis that pitted private owners against local government, riders and community groups. Advocates lambasted the private owners for their profit-first tactics, pointing to the dividends gained by the private owners. These owners, the Midland Transportation Corporation, also owned the mass transit companies in Milwaukee, Wisconsin and Louisville, Kentucky. Indianapolis politicians, residents and newspapers, all firmly conservative, hoped private owners could continue to operate Indianapolis Transit Systems without public assistance. The imminent failure prompted a discussion of the future of transportation in the city of Indianapolis. Community groups hoped the new public corporation would increase service for Indianapolis and not continue the skeleton system managed by the private owners. A storm of uncontrollable events prevented the robust expansion of the new public corporation and its lack of funding resulted in a continuing decline of service, much akin to the private owners that were abhorred by transit riders. Public ownership in Indianapolis revealed the importance of public ownership in the historiography of mass transportation and urban history. The regional investigation of Midland Transportation confirmed the notion of transit as a unique industry, both in its industrial relations and influence of the locality. The basic rationale for public ownership in Indianapolis would be the most important: the provision of public transportation for those unable to afford private transportation to obtain necessary services.

Enhancing the Photovoltaic Efficiency of a Bulk Heterojunction Organic Solar CellSahare, Swapnil Ashok 01 April 2016 (has links)
Active layer morphology of polymer-based solar cells plays an important role in improving power conversion efficiency (PCE). In this thesis, the focus is to improve the device efficiency of polymer-based solar cells. In the first objective, active layer morphology of polymer-solar cells was optimized though a novel solvent annealing technique. The second objective was to explore the possibility of replacing the highly sensitive aluminum cathode layer with a low-cost and stable alternative, copper metal. Large scale manufacturing of these solar cells is also explored using roll-to-roll printing techniques.
Poly (3-hexylthiophene) (P3HT) and phenyl-C61-butyric acid methyl (PCBM) were used as the active layer blend for fabricating the solar cell devices using bulk heterojunction (BHJ), which is a blend of a donor polymer and an acceptor material. Blends of the donor polymer, P3HT and acceptor, PCBM were cast using spin coating and the resulting active layers were solvent annealed with dichlorobenzene in an inert atmosphere. Solvent annealed devices showed improved morphology with nano-phase segregation revealed by atomic force microscopy (AFM) analysis. The roughness of the active layer was found to be 6.5 nm. The nano-phase segregation was attributed to PCBM clusters and P3HT domains being arranged under the solvent annealing conditions. These test devices showed PCE up to 9.2 % with current density of 32.32 mA/cm2, which is the highest PCE reported to date for a P3HT-PCBM based system.
Copper was deposited instead of the traditional aluminum for device fabrication. We were able to achieve similar PCEs with copper-based devices. Conductivity measurements were done on thermally deposited copper films using the two-probe method. Further, for these two configurations, PCE and other photovoltaic parameters were compared.
Finally, we studied new techniques of large scale fabrication such as ultrasonic spray coating, screen-printing, and intense pulse light sintering, using the facilities at the Conn Center for Renewable Energy Research at the University of Louisville. In this study, prototype devices were fabricated on flexible ITO coated plastics. Sintering greatly improved the conductivity of the copper nano-ink cathode layer. We will explore this technique’s application to large-scale fabrication of solar cell devices in the future work.
