Civilizing the tropics: The highlanders' failed attempt to transform the Colombian Amazon, 1850--1930

The subject of this dissertation is the nature of the environmental transformations, both symbolic and physical, that took place in Colombia between 1850 and 1930. This period begins with the attempt by the Colombian elite to leave behind colonial ties, overcome economic disorganization, and link Colombia to the international market. These efforts were part of a general project to “civilize” this tropical country. The period closes with the transition toward an industrialization and urbanization process led by the Colombian state during the 1930s. ^ Frequently, environmental studies as an academic field are dominated by biological concerns. However, most environmental thinking accepts their interdisciplinary nature. Under this framework not only spatial but also symbolic concerns are key elements in understanding environmental transformations. ^ This study finds that despite several attempts to transform the Colombian landscape physically, most of the substantive changes were localized and circumscribed to the Andean region. Other changes were mainly symbolic. This dissertation thus uses the Amazon as one of several regions that did not experience significant changes in the forest canopy. While highlanders originally dreamed of the Amazon as an untapped El Dorado, their failed attempts to exploit the region caused them to imagine it as a nightmarish “green hell”. ^ This dissertation concentrates on three pairs of concepts: tropicality/civilization, landscape/territory, and symbolic/material changes. It presents both a general vision of Colombia and case studies of three regions: Cundinamarca, and Cauca Valley are used to compare with the Amazon region that is developed at length. Whereas mainstream Colombian histories have either fixated on the Andean highlands or, in a relegated second place, on the Caribbean region, this dissertation attempts to significantly contribute to the historiography of Colombia by focusing on the largely neglected Amazonian region. ^ To understand imageries about Colombia's landscape, the dissertation relies on travel writings, chorographic descriptions and maps. It also makes uses legal documents and other published primary sources, including literary pieces and memoirs. ^

A decision support framework for infrastructure maintenance investment decision-making

Infrastructure management agencies are facing multiple challenges, including aging infrastructure, reduction in capacity of existing infrastructure, and availability of limited funds. Therefore, decision makers are required to think innovatively and develop inventive ways of using available funds. Maintenance investment decisions are generally made based on physical condition only. It is important to understand that spending money on public infrastructure is synonymous with spending money on people themselves. This also requires consideration of decision parameters, in addition to physical condition, such as strategic importance, socioeconomic contribution and infrastructure utilization. Consideration of multiple decision parameters for infrastructure maintenance investments can be beneficial in case of limited funding. Given this motivation, this dissertation presents a prototype decision support framework to evaluate trade-off, among competing infrastructures, that are candidates for infrastructure maintenance, repair and rehabilitation investments. Decision parameters' performances measured through various factors are combined to determine the integrated state of an infrastructure using Multi-Attribute Utility Theory (MAUT). The integrated state, cost and benefit estimates of probable maintenance actions are utilized alongside expert opinion to develop transition probability and reward matrices for each probable maintenance action for a particular candidate infrastructure. These matrices are then used as an input to the Markov Decision Process (MDP) for the finite-stage dynamic programming model to perform project (candidate)-level analysis to determine optimized maintenance strategies based on reward maximization. The outcomes of project (candidate)-level analysis are then utilized to perform network-level analysis taking the portfolio management approach to determine a suitable portfolio under budgetary constraints. The major decision support outcomes of the prototype framework include performance trend curves, decision logic maps, and a network-level maintenance investment plan for the upcoming years. The framework has been implemented with a set of bridges considered as a network with the assistance of the Pima County DOT, AZ. It is expected that the concept of this prototype framework can help infrastructure management agencies better manage their available funds for maintenance.

Análise computacional do desempenho de estratégia para o religamento controlado de linhas de transmissão

The search for mitigation solutions, with respect to the effects of overvoltages linked to the energization and reclosing maneuvers of transmission lines include a challenging subject with strong impact on the insulation coordination of electrical systems. Although the recognition of classical and commercial proposals to mitigate these phenomena, other possibilities are certainly still worthwhile highlighting and investigations. In this context, the present work is grounded in the exposure of the physical and mathematical foundations of a strategy based on controlled switchings, whose moments to the line reclosing are pre-programmed. The computational evaluation of the effectiveness of the methodology is made using the ATP simulator, which are studies in a typical electrical system subjected to the action of short-circuits fallowed by shutdowns and subsequent reclosing, under the action of technology here focused and lack thereof.

Noção de simetria na cosmologia de Anaximandro de Mileto

Through the philosophical movements in Ionia and through researches made on phýsis (started by the first wise men in Miletus), we elected Anaximander‟s cosmology as a fertile ground for exploring the Greek notion of symmetry. From a geographical perspective, initially, the Greeks‟ originality towards the notion of a due measure will be questioned, since the astrological and mathematical knowledge were common in Babylon and Egypt. Although the cultural environment on the Milesian commercial ports and its architecture show evidences of a possible eastern impact on the Greek thought, it will be noted (from fragments validated by the Doxography tradition) that the problem with the birthplace of the notion of harmony and of due measure is something specific of the Greek culture and inherent to its remote religiosity. The resumption of these notions refers to the issue of arché and to its divinity assumed by Thales, Anaximander and Anaximenes. The divine was not an extrinsic notion to the Milesian thought towards the first element. Therefore, we will have as a result of this investigation some assumptions for which the notion of symmetry in Anaximander, stated in his ápeiron, could be, from the dialogue between philosophy and Orphism, an assimilation of the One, as witnessed in the Derveni papyrus.

A MULHER ALÉM DO BEM E DO MAL: Malévola e a representação cinematográfica do feminino integrado

Estudo sobre as construções simbólicas e identitárias da mulher presentes na narrativa e na estrutura das personagens femininas do filme Malévola (2014) – produção dos estúdios Disney (EUA). A narrativa é inspirada no conto de fadas “A Bela Adormecida do Bosque” e distingue-se pela perspectiva feminina, modificando as possibilidades de interpretação, além de possibilitar a quebra do paradigma dicotômico relacionado ao Bem e ao Mal. A pesquisa tem por objetivo estudar a evolução das construções imaginárias da mulher no cinema e traçar paralelos entre as características arquetípicas das personagens de Malévola em relação à identidade da mulher na contemporaneidade. Para tal, será tomado como referencial teórico os estudos do imaginário social, com as obras de Gilbert Durand, Edgar Morin e, em especial, Michel Maffesoli; conceitos da psicanálise a partir dos trabalhos de C.G. Jung, Erich Neumann, Marie-Louise Von Franz e Clarissa Pinkola Estés; as teorias de Stuart Hall, Laura Mulvey e Gilles Lipovetsky relacionadas aos estudos culturais com ênfase em gênero; e também o ecofeminismo através dos trabalhos de autoras como Vandana Shiva e Maria Mies. Nosso referencial teórico-metodológico é a Hermenêutica de Profundidade (HP) visando à interpretação da estrutura simbólica de nosso objeto. Resultam desta pesquisa a verificação de um processo de saturação de padrões identitários e simbólicos provindos da modernidade e a evolução de novas dinâmicas nas narrativas presentes nas mídias e na comunicação.
