Fabrication Laboratories: Problems and possibilities of implementation in Latin America.

Herrera Polo, Pablo C., Juárez, Benito, Universidad Peruana de Ciencias Aplicadas (UPC) 07 1900 (has links)
Proceedings from the Fab 9 Research Stream 9th International Fablab Conference, 21-27 July 2013, Yokohama. / Since 2007, Latin America has incorporated a set of emerging techniques promoted under three initiatives: a) from the experience of Master and Doctoral students who return to their home countries and promote their experience, b) from the external academic experience that goes towards the region, and c) from self-learning. These experiences are developed in an academic area, unlike Europe or the U.S., where they were promoted from and to professional practice, with varying degrees of implementation and effect. Generally speaking, the academic programs of the region lack a policy of inclusion of systematized emerging technologies, and that produces a slow uptake, especially in architecture. On one hand, if educational policies are not stable, equipment investment cannot be stable, and on the other hand, the generation gap between those who promote and those who accept blends into disruption and status quo. Each implementation in the region produces adverse and complex patterns, replicating existing models and seeking alliances with institutions in developed countries. Thus, there are self-help groups, while others incorporate academic, technical and/or commercial supervisions, in principle through the Center for Bits and Atoms (MIT Fab Lab) and McNeel Associates (Rhino Fab Lab). In this research, we evidence evolution and implementation processes in Latin America of the three types of initiatives, analyzing the case study in Peru, which together open up the possibility of moving from a phase of experimentation, trial and error to another that actually promotes local innovation and inclusion.

Épistémologie d’une archéologie fragmentaire : le cas virú-gallinazo, côte nord du Pérou / Epistemology of a Fragmented Archaeology : the Viru-Gallinazo Case, North Coast of Peru

Ansart, Arnaud 31 May 2010 (has links)
Le terme virú-gallinazo désigne au XXe siècle un style céramique puis caractérise une culture. Aujourd’hui, le consensus archéologique regroupe les vestiges virú-gallinazo sous la dénomination de « phénomène culturel » et cherche ainsi à le définir. Mais l’épistémologie montre l’aspect fragmentaire sur lequel se fondent ces interprétations.Cette thèse propose alors une approche plus complexe du phénomène. Elle se fonde sur les idées suivantes : l’art ne reflète pas l’intégralité des manifestations culturelles. Enfin la signification d’un objet peut varier selon les contextes dans lesquels il se trouve. Ce travail, en conséquence, entreprend une analyse contextuelle croisée des différentes catégories de vestiges. / During the XXth century, the viru-gallinazo term first refers to ceramic’s style and after it distinguishes a culture. Today, the archaeological consensus includes the viru-gallinazo remains as a"cultural phenomenon" and seeks to define it. But the epistemology shows the fragmented aspect on which are based those interpretations.This thesis proposes then a more complex approach of the viru-gallinazo "cultural phenomenon". It is based on the following ideas: art does not reflect the entirety of cultural events. Finally the meaning of an object may vary according to the context in which it is located. For that reason, this study sets out a crossed contextual analysis of the different categories of remains.

Každodennost jezuitských misionářů z České provincie v Jižní Americe / Everydayness of Jezuit missionaires from Czech province in South America

Vilímcová, Zuzana January 2013 (has links)
This thesis deals with the sub-themes of everydayness of Jesuit missionaries from Czech province in South America. The author, using sources and literature of domestic and foreign origin, handles questions related to journeys of the Jesuits to South America, mapping their main routes, emotions and experiences, trying to ascertain what the material support of missionaries was and what kind of dangers they met across the ocean. She attempts to reconstruct the course of missions during ordinary as well as festive days and analyses missionary methods currently applied on the Indian population in South America. She refers to limited opportunities of Jesuits' contacts with the homeland, but also with other missionaries. Finally, she handles the questions of how the purposes of the missions could have been reached and how missionaries managed to survive in tough conditions of the missions, but also after the subsequent expulsion and cancellation of the order. Key words: Missionaries, Jesuits, everydayness, South America

Methane cycling in upland soils of the Peruvian Andes and Amazon

Jones, Samuel Peter January 2015 (has links)
Significant discrepancies exist in global estimates of the atmospheric methane (CH4) budget. This is particularly true for tropical South America where bottom-up approaches, rooted in field observation, tend to under estimate atmospheric observations. As such, a better understanding of soil environments, which are capable of acting as both source and sink for atmospheric CH4, is required. Soil-atmosphere CH4 exchange is fundamentally determined by the balance between strictly anaerobic methanogenic and aerobic methanotrophic microbial processes. For this reason, CH4 emissions are typically associated with anoxic wetland soils, whilst, oxic upland soils are thought to uptake CH4 from the atmosphere. However, there is increasing evidence that upland soils may act as sources of CH4 through methanogenic activity within cryptic wetlands or anoxic microsites. This thesis aims to: document soil-atmosphere CH4 fluxes in poorly represented tropical upland and montane ecosystems, investigate controls on CH4 flux with a focus on soil oxygen (O2) concentration and investigate relationships between methanogenic and methanotrophic processes under oxic conditions. These aims are addressed in three chapters focusing on lowland terra firme, premontane and montane forests and montane humid puna grasslands and wetlands along an Amazonian to Andean transect spanning ~ 3300 m of elevation in southeastern Peru. In the lowland rainforest intensive seasonal field campaigns and laboratory incubations were conducted on higher porosity ultisol and lower porosity inceptisol soils. Mean (s.e.) net CH4 fluxes for dry and wet seasons were, respectively, -1.59 (0.06) and - 1.39 (0.07) mg CH4-C m−2 d−1 for the ultisol and -0.95 (0.06) and -0.41 (0.10) mg CH4-C m−2 d−1 for the inceptisol. Greater uptake rates in the ultisol than the inceptisol were best explained by lower water-filled pore space (WFPS). Similarly, WFPS best explained between season variation in net CH4 flux from the inceptisol, whilst, we were unable to explain the smaller variations observed for the ultisol. Methanogenic processes were active in both the ultisol and inceptisol soils despite oxic conditions. In the premontane and montane forests, long-term monthly field measurements were conducted over two and a half years in premontane, lower montane and upper montane settings. Mean (s.e.) net CH4 fluxes for aggregated dry and wet season months were, respectively, -0.20 (0.15) and -0.08 (0.13) mg CH4-C m−2 d−1 for the premontane forest, -1.12 (0.13) and -0.97 (0.11) mg CH4-C m−2 d−1 for the lower montane forest and -1.55 (0.13) and -1.04 (0.11) mg CH4-C m−2 d−1 for the upper montane forest. Increased uptake with elevation was best explained by decreases in WFPS. Significant variation in net CH4 flux between seasons, driven by variation in WFPS, was only identified for the upper montane forest.

Indians and underdogs: notions of identity and the symbolic language of resistance in coastal Ecuador

Unknown Date (has links)
This thesis examines identity as a process, how it is a reflection of, or reaction to, social, economic, and political circumstances. Identity is examined, through an ethnographically informed analysis, as it is represented, contested, and focused in the visual discourse of a small population. The research suggests that identity manifests at specific and strategic moments within the symbolic practices of resistance in coastal Ecuador. Grievances to economic and political power structures are acted out in clear-cut identity terms, or motifs, and function to organize diverse interests into social action. The study illustrates two identity motifs that are commonly asserted in the local context: depictions of being indigenous and of being the underdog. Using local examples, this thesis addresses the complexities of identity formation, examines the strategic capacity of identity, and offers insight into the relationships between identity, resistance, and power. / by Sarah Anne Nohe. / Thesis (M.A.)--Florida Atlantic University, 2008. / Includes bibliography. / Electronic reproduction.

Opposition politics and populism: a comparative analysis of South American populist governments

Unknown Date (has links)
This thesis examines the relationship between the political opposition and populism. The goal is to identify when, how, and under what circumstances an opposition to a populist leader affects change to the political system. A comparative historical analysis is employed as five case studies from South America are examined. The evidence presented in these case studies demonstrates that the political oppositions in each country were unsuccessful in affecting change to their respective political systems. They were unable to demobilize the support base that the populist leaders had created. Change came to the political systems in four out of the five case studies only when the populist leader's actions demobilized his support and not from the actions of the opposition. / by Morgan Alissa Weiss. / Thesis (M.A.)--Florida Atlantic University, 2009. / Includes bibliography. / Electronic reproduction.

Um estudo sobre a evolução do MERCOSUL: do regionalismo aberto ao regionalismo pós-hegemônico / A study about MERCOSULs evolution: from open regionalism to post-hegemonic regionalism

Corrêa, Isabela Furegatti 24 August 2015 (has links)
O presente trabalho tem como objetivo analisar a evolução do regionalismo latinoamericano, sobretudo confrontando-se as principais características dos modelos de regionalismos no continente, caracterizados como aberto e pós-hegemônico. Ambos os regionalismos demarcam os períodos de criação e desenvolvimento do principal bloco econômico da América do Sul, o Mercosul, e determinaram suas transformações e seu desempenho. Tendo-se em vista sua relevância na história e nas mudanças do modelo da integração na região, por meio da análise histórica, o presente trabalho estuda os motivadores quando de sua criação, estrutura, relevância regional e como, ao longo dos anos, sofreu alterações devido às influências externas e domésticas de seus países membros, fatores estes fortemente influenciadores dos modelos de integração específicos que conformaram o bloco, denominados como regionalismos estratégico, social e produtivo. Com isso, busca-se demonstrar que o Mercosul reflete as transformações econômicas, políticas e sociais ocorridas ao final do século XX, culminando em sua criação, e transformando-o substancialmente na primeira década do século XXI. / This paper focuses on the analysis of the Latin Americas regionalism evolution, especially confronting the main features of regionalism models in the continent characterized as \"open\" and \"post-hegemonic. Both regionalisms characterize the periods of creation and development of the main economic bloc in South America, Mercosur, and determine its transformations and performance. Due to its relevance in history as well as in the transformation of the regional integration pattern, through a historical analysis, this paper studies the issues that motivated its creation, structure, importance in the region and how, over the years, has changed due to external and domestic influences of its members, which strongly influenced in specific models of integration that composed the Mercosur, called strategic, social and productive regionalisms. Thus, it aims to demonstrate that Mercosur reflects the economic, political and social changes that occurred at the end of the twentieth century, culminating in its creation and development, modifying it substantially in the first decade of the current century.

Paleopathology of human remains from the Plaza San Marcos, Quito, Ecuador

Unknown Date (has links)
Skeletal remains provide an exceptional opportunity to document the biological adaptations that a population undergoes in response to environmental, political and economic changes (Perry, 2007). For over 35 years, bioarchaeological analyses have documented such changes indigenous Ecuadorians. In 2007, Victoria Dominguez excavated remains at the Plaza San Marcos in Quito, Ecuador. I analyzed these remains, documented evidence of pathologic conditions and trauma, and compared this native population to other indigenous populations and to European cohorts. My analyses revealed increased violence and pathologic conditions in the Plaza San Marcos population when compared to populations occupying Quito prior to colonization and during Spanish control. Indigenous remains also exhibited more pathologic conditions and trauma than European remains. Historic accounts of life in Quito describe increased violence and hardships for natives following emancipation from Spain. My analyses did not reveal increased interpersonal violence, but did demonstrate evidence of increased general pathologies following independence. / by Ronda R.

Estudo da estrutura e energética dos distúrbios de escala sinótica na costa leste da América do Sul / Structure and Energetics of the synoptic-scale disturbances over the South America eastern coast

Pinto, João Rafael Dias 15 March 2010 (has links)
A atmosfera é um complexo sistema termodinâmico na qual a geração, conversão e dissipação de energia desempenham um papel fundamental no desenvolvimento e manutenção dos diversos sistemas de movimento de escala sinótica e na circulação geral. Neste trabalho, o ciclo de energia de Lorenz em área limitada foi aplicado para três casos de ciclogêneses, onde cada um desses se formou em uma das três principais regiões ciclogenéticas da costa leste da América do Sul. Além disso, foram analisadas as condições sinóticas, bem como a evolução da estrutura tridimensional de cada sistema desde o período prévio à formação até o seu decaimento. As análises mostraram que o ciclone que se formou na costa sul/sudeste do Brasil originou-se a partir de uma baixa desprendida nos níveis médios em uma região de fraca baroclinia. As conversões de energia mostraram que o sistema extraía energia cinética do escoamento zonal médio indicando, assim, que a instabilidade barotrópica foi dominante na sua formação. O sistema que se desenvolveu região da foz do Rio da Prata apresentou características de uma ciclogenêse do tipo bomba, com rápida intensificação. Além disso, devido à esse rápido crescimento foi observado a seclusão das frentes quente e fria. O ciclo de energia mostrou uma natureza baroclínica com forte contribuição de geração de energia potencial disponível pela liberação de calor latente da convecção. Já o sistema da região da costa sul da Argentina apresentou um desenvolvimento baroclínico clássico (com conversão de energia potencial disponível para energia cinética da perturbação) de uma ciclogenêse extratropical, desde a amplificação da onda até oclusão final das frentes associadas. Com base nessas análises observa-se que as ciclogêneses que se formam na América do Sul podem apresentar características variadas, tanto de desenvolvimento como de estrutura, que não são muitas vezes relacionadas à ciclogenêse clássica. / The atmosphere is a complex thermodynamic system in which energy generation, conversion and dissipation play a key role in the development and maintenance of the synoptic scale movement systems. In this paper, the Lorenz energy cycle in a limited area was applied for three cases of cyclogenesis, where each one of them formed in an important cyclogenetic region in the east of South America. Furthermore, the synoptic conditions were analyzed, as well as the evolution of the tridimensional structure, from its early formation until its decay. The analysis showed that the cyclone, which formed on Brazil south/southeastern coast, originated through a cut off low in the mid levels on a weak baroclinic region. The energy conversions indicated the system extracted kinetic energy from the basic flow, showing that the barotropic instability was dominant in its development. The system that occurred in the Rio da Prata mouth had features of a bomb-type cyclogenesis with fast intensification. Moreover, due to this event, the fronts seclusion were observed. The baroclinic nature with a strong contribution from the available potential energy generation term, through the latent heat release of the convection, can be observed by the conversion terms. Meanwhile, the system of the Argentina south coast presented a classical baroclinic development (which has the conversion from eddy available potential energy to eddy kinetic energy) of an extratropical cyclogenesis, from the wave amplification until the final occlusion of the associated frontal system. Based in this analysis, it is worthy to note that both the development and structure of the cyclogenesis that occur in the South American eastern coast can present varied features, which are often not related to classical cyclogenesis.
