Point of this diploma thesis is analyzing of three railroad crossing controlled by institutions of South-Moravian region, which are chosen by author. For analysis were chosen problematic railroad crossing where happened in last five years traffic accidents with consequences of death. Next criterion of choosing was type of security device. Chosen railroads crossing are representing all types of normally used security devices. That is why was chose railroad crossing with only warning crosses, light security device and last one with light security device with barrier beam. Theoretical part aims on: Basic parameters, dividing, numbering, system of function and marking of railroad crossing. In practical part, there are used mathematical calculations for assessment of safety on chosen railroad crossing and for determination of possibilities of averting a collision of both participants. Corrective measures are made for each railroad crossing taking to account it’s financial conditions. For each railroad crossing is made polygon with help of program Virtual Crash 3.

The aim of the diploma thesis was to design an electromagnetic generator to the purpose of supplying signalling and safety devices on the rail tracks. The electromagnetic generator is a separate electrical source, which is mainly needed for safety in the case of not covered tracks by electrical installation. The thesis proposes two types of electromagnetic generator and one with non-linear stiffness, which are designed for the passage of trains with low frequency.

The task of the thesis is to make a study of reconstruction of two railway stations: Bohdíkov and Ruda nad Moravou. The aim of the project is to prepare a plan of reconstruction, which will suit actual state of traffic. The plan must abide the rules of law, especially in the case of the entry of people with physical handicaps.The thesis contains the plan of reconstruction of platforms, a regulation of geometric parameters of tracks, reconstruction of superstructure and also rebuilding of actual drainage.

Speculative realism/historical fantasy are labels coined by Stanford University’s Ramon Saldivar. Saldivar describes this genre as “a way of documenting things that have happened, or could happen” (the realist component), but warping realism into science fiction and fantasy, blending and bending the genres (Dickason). In his 2013 article “The Second Elevation of the Novel: Race, Form and the Postrace Aesthetic in Contemporary Narrative,” Ramon Saldivar brings an interesting perspective to how a new generation of authors have taken this genre and exposed utopia as fraud. He argues that as many writers (often members of minorities) seek to challenge the status quo and explore new territories with their prose, a new genre has been born from the utopian and dystopian schools- the genre he coins “speculative realism.” Implicit in his labelling of a new genre is the assumption that existing genres (created and nurtured by the dominant groups in society) are inadequate vehicles for the sort of work these authors seek to do, and in order to make their unique contributions, they have had to become pioneers in the field. Specifically, these authors have focused on utopian and dystopian worlds and have exposed the ruling class ideology hidden in the resolution. This new genre provides perfect material from which to draw texts that encourage students to grapple with the difficult concepts of how society should be organized, and what means might be required to achieve it. This project was developed with high school pedagogical practice in the forefront, therefore texts are chosen based on genre, grade level/interest, and thematic/ideological content. Within each group, the texts are chosen to highlight the deliberate indoctrination present within the current curriculum, and through comparison demonstrate how substituting speculative realist and historical fantasy for dystopian and historical fiction novels both educates and empowers students. In the dystopian genre, the commonly taught Lord of the Flies by William Golding is compared and contrasted with Octavia Butler’s Earthseed series. To explore novels based on history, The Invention of Wings by Sue Monk Kidd is contrasted with the historical fantasy The Underground Railroad by Colson Whitehead.

While passenger rail service has significantly grown in some parts of the United States, as evidenced by the new Brightline / Virgin Rail USA service in Florida and the expansion of passenger rail service in the State of Virginia, there has been significant resistance to the growth of passenger rail service in Texas, as evidenced by the demise of the Lone Star Rail District (LSRD) in 2016. Why the resistance? This exploratory research provides insights that address that question by identifying the contributing factors that led to the LSRD’s failure. A political economy framework incorporated a stakeholders’ perspective in an analysis of LSRD’s termination. An archival document study was used to identify key stakeholders and to then inform the design of, and the questions used in, an interview study of those key stakeholders. This research identified eight factors that contributed to the demise of the LSRD; 1) prior rail / transit failures in Texas; 2) structure of the Texas legislation; 3) inadequate political support; 4) organizational paralysis; 5) resistance from the Texas Department of Transportation; 6) flawed strategy; 7) disruptive technology; and 8) the Bexar County (Texas) Judge and the president of the Union Pacific Railroad. Although hundreds of individuals were involved during the LSRD’s nineteen-year history, in the end, three key decision makers and one key staff person were attributed with ending the organization’s existence. By identifying and analyzing the constellation of forces that were at play in the Lone Star Rail District, lessons were learned that could be applied (or avoided) across an array of similar rail initiatives, not only in Texas, but throughout the United States. A clear and identifiable political champion; adequate funding; competent project management; a clear project design and budget; a cooperating Class-1 freight railroad partner; adequate property ownership or right-of-way access; and an economically competitive alternative to automated highway vehicle technology; should all be considered necessary elements for the success of future passenger rail expansion projects. / Business Administration/Interdisciplinary

[pt] Esta tese explora o impacto da infraestrutura de transporte sobre desenvolvimento econômico e os efeitos do poder político das elites agrárias no investimento em educação. O primeiro capítulo documenta o impacto da rede ferroviária brasileira na transformação estrutural da economia entre o final do século XIX e meados do século XX. Exploramos a variação induzida pela localização geográfica, onde municípios próximos às rotas de menor custo estavam mais propensos a serem conectados ao sistema ferroviário, para identificar os efeitos causais das ferrovias sobre transformação estrutural. Mostramos que a expansão da infraestrutura de transporte realoca os trabalhadores da agricultura para a manufatura. Fornecemos evidências de que a integração do mercado e a adoção de novas tecnologias pelas empresas manufatureiras são dois mecanismos importantes que explicam a mudança na estrutura ocupacional da economia. O segundo capítulo explora a persistência do impacto da rede ferroviária brasileira no desenvolvimento econômico de longo prazo entre 1950 e 2010. Exploramos a variação induzida pela localização geográfica, onde municípios próximos às rotas de menor custo tinham maior probabilidade de estarem conectados ao sistema ferroviário, para identificar os efeitos causais das ferrovias na atividade econômica. Mostramos que, apesar do declínio da rede ferroviária pós-1950, o efeito sobre desenvolvimento econômico persistiu ao longo do tempo. Nossos resultados sugerem que aglomeração e urbanização foram os principais impulsionadores da persistência da atividade econômica. No terceiro capítulo, estudamos a relação entre o poder político das elites agrárias e a disseminação da educação em massa no início do século XX no Brasil. Utilizamos um novo conjunto de dados sobre a estrutura ocupacional das elites votantes em 1905 e censos históricos para testar se locais onde mais eleitores pertenciam à elite agrícola investiam menos em educação. Constatamos que os municípios com maior participação de eleitores na agricultura têm uma menor taxa de alfabetização em 1920 e esses efeitos persistem até a década de 1970. A longo prazo, os municípios com maior participação de eleitores na agricultura têm menos anos de escolaridade e menor renda per capita. Apresentamos evidências de que o fornecimento de insumos educacionais é o principal mecanismo que explica a persistência a longo prazo. / [en] This dissertation explores the impact of transportation infrastructure on economic development and the effects of agrarian elites political power on investments in education. The first chapter documents the impact of the Brazilian railway network on structural transformation between the late nineteenth and middle twentieth century. We exploit variation induced by geographic location, where municipalities near the least-cost routes were more likely to be connected to railway system, to identify the causal effects of railroads on structural transformation. We show that the expansion of the transportation infrastructure shifts the workers from agriculture to manufacturing. We provide evidence that market integration and the adoption of new technologies by manufacturing firms were two important mechanisms that explain the change in the occupational structure of the economy. The second chapter explores the persistence of the impact of Brazil s railway network on long-run economic development between 1950 and 2010. We exploit variation induced by geographic location, where municipalities near the least-cost routes were more likely to be connected to railway system, to identify the causal effects of railroads on economic activity. We show that, despite the decline of the railway network post-1950s, the effect on economic development persisted. Our findings suggest that agglomeration and urbanization were key drivers of economic activity persistence. In the third chapter, we study the relationship between the political power of agrarian elites and the spread of mass schooling in the early 20th century in Brazil. We use a novel dataset on the occupational structure of the voting elites in 1905 and historical censuses to test whether places, where more voters belonged to the agriculture elite, invested less in schooling. We find that municipalities with a higher share of agriculture voters have a lower literacy rate in 1920 and these effects persist until the 1970s. In the long-run, municipalities that had a higher share of agriculture voters have fewer years of schooling and lower income per capita. We provide evidence that the supply of educational inputs is the main mechanism that explains the long-term persistence.

In 1868, Brigham Young signed a grading contract with the Union Pacific Railroad to work on the transcontinental line in Utah. He sublet the job to other contractors who completed the work in February 1869. When the project was finished, there was still a great deal of money owed to Brigham Young by the Union Pacific and because of their financial difficulties, they were not able to meet the obligation immediately. To resolved the debt, Young sent Bishop John Sharp and Joseph A. Young to Boston in an effort to effect a settlement with the company. They obtain a partial settlement in August 1869, and the following year John Sharp completed a final settlement with the railroad.Although the negotiations between Young's representatives and the railroad resulted in a compromise settlement, it was equitable and satisfactory to both parties.

[pt] A pesquisa sobre os vendedores ambulantes se insere em um contexto mais amplo, em uma sociedade determinada: a sociedade capitalista, onde o cotidiano de trabalho desses sujeitos pode nos revelar as facetas mais obscuras do processo de precarização e informalização do trabalho, cada vez mais presente no mundo contemporâneo. Por entendermos, através de diversas leituras, que a exploração capitalista e a dominação patriarcal caminham de forma conjugada e não podem ser vistas de maneira cindida, a análise do processo de precarização do trabalho se relacionou a uma perspectiva de gênero. Com este propósito, resolvemos focar no trabalho das mulheres em um mercado tão competitivo como o dos ambulantes no transporte ferroviário de circulação de pessoas da Região Metropolitana do Rio de Janeiro. Também utilizamos a categoria território para apreender as relações de poder, e com isso as de gênero, produzidas e reproduzidas pelos ambulantes nesse transporte. Visando alcançar os objetivos da pesquisa foi realizado um trabalho de campo, que teve início em janeiro de 2022 e foi concluído em maio deste mesmo ano. O trabalho de campo consistiu em observação participante e em entrevistas com trabalhadores ambulantes nos cinco principais ramais dos trens urbanos da RMRJ. Foram realizadas 6 (seis) entrevistas semiestruturadas de forma completa, além do depoimento de outros ambulantes dentro e fora do transporte ferroviário. Também foram acessados dados secundários de institutos de pesquisa e realizada revisão bibliográfica. Tudo isso nos possibilitou ferramentas teóricas e metodológicas para analisar as experiências de mulheres trabalhadoras que vivenciam a precariedade em territórios de maioria masculina. / [en] Research on hawkers is inserted in a wide context determined by the capitalist society in which their daily work can reveal to us the most obscure facet of the process of informalization and precarization of labor that is increasingly present in the contemporary world. By means of several readings, we understand that capitalist exploitation and patriarchal domination are tightly connected and cannot be separated, thus, the analysis process of precarization of labor is related to a gender perspective. To this end, we focused on women working in the extremely competitive hawker’s market of rail transport in the Rio de Janeiro metropolitan area. We use the category called territory to seize the power relations and also gender relations produced and reproduced by hawkers in this means of transport. Aiming to achieve the purpose of the research, fieldwork started in January 2022 and ended in May 2022. The fieldwork consisted in observing and participating and interviewing the hawkers in the five principal RMRJ branches of train lines. We did six completed and semi-structured interviews in addition to other hawkers brief inside and outside railroad transportation. We also accessed secondary data from research institutes and we did literature review. All of it gave us theoretical tools and methodology to analyze the experience of women who experience precarity in male majority places.

[pt] Este estudo teve como objetivo apreender as experiências dos trabalhadores ambulantes nos trens urbanos de passageiros que circulam na Região Metropolitana do Rio de Janeiro (RMRJ). Trata-se de pesquisa que desenvolve e aprofunda o estudo de mestrado da autora, intitulado Uma vida de andanças: trabalho, precarização e os ambulantes dos trens da Região Metropolitana do Rio de Janeiro. Na atualidade, todos os ambulantes que trabalham nos trens da RMRJ desenvolvem suas atividades no espaço ferroviário de forma clandestina, pois não é permitido pela concessionária que administra a ferrovia da RMRJ - a Supervia -, o trabalho ambulante naquele espaço. Para o desenvolvimento da pesquisa, o trabalho de campo teve início, de modo mais sistemático, em março de 2018 e foi concluído no segundo semestre daquele ano. O trabalho de campo consistiu em observação participante das dinâmicas dos sujeitos que trabalham na ferrovia e em entrevistas com trabalhadores ambulantes nos cinco principais ramais dos trens urbanos da RMRJ (Deodoro; Santa Cruz; Japeri; Belford Roxo e Saracuruna). Foram realizadas 16 (dezesseis) entrevistas semiestruturadas com trabalhadores ambulantes, que vendiam as mais distintas mercadorias, nas plataformas da ferrovia e/ou nas composições dos trens. De forma complementar, foi utilizada uma diversidade de fontes documentais oficiais, além de jornais, revistas, mídias sociais, imagens, além de depoimentos de ambulantes que trabalhavam em outros espaços urbanos. Também foram acessados dados secundários de institutos de pesquisa e realizada revisão teórico-bibliográfica. Neste processo de pesquisa e de construção acadêmico-científica, a categoria trabalho foi aprofundada, assim como os conceitos de classe e experiência. No desenvolvimento e discussão da tese, são articulados, também, o processo de precarização estrutural do trabalho, no sistema capitalista, e as experiências dos ambulantes nos trens da RMRJ, destacando-se, assim, a superexploração do trabalho a que estão submetidos. Outro eixo da investigação realizada é o da questão urbana, tanto discutindo teoricamente esta categoria quanto apresentando-se, historicamente, o espaço do Rio de Janeiro e da ferrovia. Nessa direção, são desenvolvidas e articuladas as discussões teórico-empíricas sobre o espaço urbano, o direito à cidade e sua apropriação pelos trabalhadores ambulantes como seu locus de trabalho. Na perspectiva de articular trabalho e reprodução social, são apresentados elementos que circundam a reprodução desta fração da força de trabalho, bem como de suas famílias. Adicionalmente, são apresentadas as experiências de trabalho dos ambulantes no espaço da ferrovia da RMRJ, identificando seus conflitos e contradições, bem como possíveis formas de resistência desses trabalhadores. Esta resistência é expressa como vinculada a estratégias de sobrevivência, identificando-se as peculiaridades de trabalho, condições e modo de vida desses trabalhadores. A chave de leitura adotada, que compreende a experiência do trabalho ambulante como uma estratégia de sobrevivência, marcada por condições precárias de trabalho e de vida, permite afirmá-la como uma forma singular de resistência destes trabalhadores ambulantes na ferrovia da RMRJ. / [en] This study sought to capture the experiences of hawkers in urban passenger trains that circulate on the Rio de Janeiro Metropolitan Region (RJMR), Brazil. This is a deepening of the study that culminated in the master s dissertation entitled A life of wandering: work, precarization and the hawkers of the trains of the Metropolitan Region of Rio de Janeiro. Currently, all the hawkers working on the RMRJ trains work in a clandestine way, since their work is not permitted SuperVia, the company who manages the RMRJ railroad, the traveling work in that space. For the elaboration of the present study, the empirical field was entered, in a more systematic way, starting in march of 2018, until the second semester of the same year. The field work consisted of participant observations of the dynamics of the subjects that work in the railroad and in interviews with hawkers on the five main lines of the urban trains of the RMRJ (Deodoro, Santa Cruz, Japeri, Belford Roxo and Saracuruna). Sixteen semi-structured interviews were realized, carried out on the platforms of the railway and also in the composition of the train, with hawkers who worked selling a wide sort of products. Complementary, a variety of sources were used, such as official documents, newspapers and magazines, social medias, pictures and testimonials from hawkers working in other urban spaces. Secondary data from research institutes and bibliographic research were also accessed, as and carried out theoretical-bibliographical review. In this process of research and academic-scientific construction, the work category was deepened, as were the concepts of class and experience. In the discussion and development of the thesis, the process of structural precarization of the current work in the capitalist system and the work experiences of the hawkers in the trains of the RMRJ were also articulated. It emphasized, therefore, the overexploitation of the work to which they are submitted. Another axis of the realized investigation is that of the urban question, both theoretically discussing this category as historically presenting the Rio de Janeiro s and the railroad s space. In this direction, theoretical-empirical discussions on urban space, the right to the city and the appropriation of the city by hawkers as their work locus were developed and articulated. In the perspective of articulating work and social reproduction, elements that surround the reproduction of this fraction of the work force, as well as their families, are presented. Additionally, experiences concerning the work of the hawkers in the railroad space of the RMRJ were presented, identifying its conflicts and contradictions, as well as the possible forms of resistance of these workers. This resistance is expressed as related to survival strategies, identifying the work peculiarities, conditions and way of lives of these workers. The reading key adopted, which comprehends the experience of hawkers as a survival strategy, marked by precarious working and living conditions, allows us to affirm it as a unique form of resistance of these workers on the RMRJ railroad.
