This dissertation outlines the creation and history of the Fort Worth Stockyards Company from its conception to the time of this dissertation's publication. The Fort Worth Stockyards Company was created by Greenleif W. Simpson and Louville V. Niles. This company would soon cement Fort Worth as the premier livestock producer in America, soon surpassing Chicago.

Em uma cadeia produtiva de minério, as operações de pátio de estocagem, principalmente as de recuperação de pilhas de minério, exercem um papel fundamental por vincularem os processos de beneficiamento e de transporte. Com esta finalidade, esta dissertação propõe o sequenciamento das pilhas de minério a serem recuperadas através da adaptação de heurísticas trazidas pela literatura. Primeiramente, propõe-se uma heurística de sequenciamento para a retomada de pilhas de minério (entendidas como tarefas a serem sequenciadas) nos seus respectivos pátios através da aplicação de um índice de priorização de pilhas (IP). Tal índice apoia-se em fatores relevantes para as operações de pátios de estocagem, como capacidade das recuperadoras, qualidade e tempo de residência do minério e tempo de deslocamento entre pilhas (setup). A segunda heurística proposta, ATCSM (Apparent Tardiness Cost with Setups for mineral recovery), modifica a regra de despacho ATCS (Apparent Tardiness Cost with Setups) com vistas à sua aplicação na retomada de pilhas de minério em pátios de recuperação. O ATCSM apoia-se em fatores tidos como relevantes para as operações de pátios de estocagem, como tempo disponível para o empilhamento de um produto e data de entrega de uma pilha, entre outros. Os métodos propostos foram aplicados em um sistema de recuperação de minério composto por dois pátios, duas máquinas recuperadoras e doze pilhas. As sequências de recuperação geradas pelas heurísticas propostas foram consideradas coerentes por especialistas de pátio de estocagem de uma empresa mineradora. / In the supply chain of ore operations, stockyard operations, mainly the recovery of ore piles, play a fundamental role between beneficiation and transport processes. This thesis proposes new scheduling heuristics for sequencing ore piles recovering order. The first heuristics proposes a pile prioritization index (IP) that relies on relevant factors for stockyards operations, including machines capability, ore quality and residence time, and travel time between piles (setup). With similar purposes, the second heuristics modifies the dispatching rule ATCS (Apparent Tardiness Cost with Setups), yielding the ATCSM (Apparent Tardiness Cost with Setups for mineral recovery). The proposed ATCSM also relies on factors regarded as relevant to stockyard operations, as time available for stacking of a product and piles due date, among others. The proposed methods were applied to an ore recovery system composed of two stockyards, two recovery machines and twelve piles. The recovery sequences generated by both heuristics were considered consistent by experts from a mining company.

This dissertation examines the establishment and influence of the International Livestock Exposition, an annual show that began in Chicago in 1900 and that served as the central hub of the national livestock improvement movement. Industrial meatpacking firms and land-grant university professors worked together to transform the genetic composition and physiology of American meat-producing animals. Packers hosted the Exposition at the Union Stockyards to address market irregularities in quality and supply. University researchers intended to solve a larger set of problems that included rural population decline, the need for more food output to feed a growing population, and diminishing soil fertility. These unlikely partners created the International to eliminate inferior, or “scrub,” livestock. The International played a pivotal role in remaking livestock genotypes and phenotypes. Its organizers and participants favored “improved” animals descended from purebred, British livestock with recorded ancestries—a preference rooted in the reformers’ pseudo-scientific belief in eugenics. Purebred animals had standard bodies with a narrow set of physiological outcomes, which amounted to biotic technology. But genetic homogeneity was only a building block for improvement. The International also employed contests, demonstrations, and advocacy to reconfigure American livestock by making them smaller, more compact, and early-maturing. This study also analyzes the larger shift in American agriculture toward the Corn Belt model of grain feeding. Treating animals as dynamic historical agents, it suggests that machinery, tractors, seeds, and implements did not alone accomplish the industrialization of agriculture. Meat-producing cattle, sheep, and pigs were a requisite component in an emerging industrial sequence. These grain-fed modern livestock and their farmer caretakers fit into a developing web of mutually dependent agricultural specialists. The International united this movement into a singular body at the end of each year in Chicago, and in the process, shaped American agricultural practices and encouraged farm specialization until the show closed in 1975. Sources consulted include land-grant university research and publications, meatpacker records and propaganda, and newspaper and agricultural journal articles.

Community development is an ongoing issue that faces communities as they develop. This is a case study where two communities where faced with an identical development proposal involving Bluegrass Stockyards. Bluegrass Stockyards a prominent livestock marketing business, located in Lexington, KY needed to relocate its facility and looked at communities in Lincoln and Woodford County Kentucky as possible new locations. By looking at the case of Bluegrass Stockyards this study is able to use Conflict Theory, Growth Theory and Frame Analysis to look at the development process and issues that was associated with this development proposal. With the two communities being faced with the same proposal, and the proposals having different outcomes, the study is able to gain a better understanding of how development occurs within these two rural communities. This study provides information to both developers and community development professionals on what issues will need to be addressed with a livestock marketing center relocation and how the different issues should be addressed in order to make the process more efficient and beneficial to the involved communities.

Indiana University-Purdue University Indianapolis (IUPUI) / As historians have expanded their interests from focusing on great men and groundbreaking events to perspectives that explore everyday experiences or ordinary people, odor emerges as an important interpretative lens. Understanding the olfactory history of communities, especially what types of odors were present and how people perceived and reacted to them, enlarges historians’ understanding of the life experiences and behaviors of people in the past. The historical study of odor provides insights into how quality of life and standards of living have changed over time. Understanding how people of different times reacted to odors suggests how they perceived the sensory world around them, including people living close by. In this thesis, I examine the olfactory conditions of the neighborhood surrounding the Union Stockyards and associated meat processing facilities on Chicago’s south side in the first decade of the twentieth century. During this period, an overpowering combination of putrid odors characterized this neighborhood, known as Back of the Yards. Various factors contributed to this malodorous “smellscape,” and it impacted the quality of life of the predominantly immigrant communities that made up the workforce and residents of that neighborhood.
