Item A 1,500-year record of late Holocene temperature variability and recent warming from Laguna Chingaza, Colombia(2012-08) Bixler, Curtis William; Shanahan, Timothy M.Rapid tropical glacier retreat over the last 50 years has been well documented, and has received significant media attention. Many studies suggest these changes are due to rising global surface air temperatures, however disentangling the effects of temperature and precipitation has hampered scientific consensus. Furthermore, because of the shortness of the instrumental record, it is difficult to assess the larger significance of the climate changes associated with the decline of tropical glaciers. Here, we present a locally calibrated, independent temperature reconstruction for the past 1,500 years from Laguna Chingaza, Colombia based on distributions of branched Glycerol Dialkyl Glycerol Tetraethers (brGDGTs) in order to assess the controls on long term temperature variability in the tropical Andes, and their relationship with growth and demise of Andean glaciers. Comparison of reconstructed temperatures with the instrumental record suggests that our proxy record faithfully records decadal to century scale trends in temperature. The largest temperature decline over the last 1,500 years was a decrease of 2.5 ± 0.3 °C during the Little Ice Age (LIA), reaching lowest temperatures during the mid-17th century, and is broadly consistent with terrestrial temperature reconstructions throughout the tropics and the higher latitudes. The structure and timing of temperature changes at Laguna Chingaza are remarkably similar to recent terrestrial temperature reconstructions from elsewhere in the tropics, including sites in the tropical Pacific and equatorial Africa, suggesting that these changes are widespread in the tropics. Together, these records suggest that warming over the last few decades is unprecedented over the last 1,500 years, including the Medieval Climate Anomaly (800-1150 AD). Comparison of these temperature changes with records of Andean glacier limits suggests that temperature is the dominant driver of glacial retreat, particularly over the past few decades. Additionally, paleotemperatures inferred from LIA and recent glacial equilibrium line altitudes (ELAs) underestimate past changes in temperature when compared with brGDGTs reconstructions, suggesting that changes in precipitation complicate the use of glacier ELAs to reconstruct past temperatures. The coupling of temperature and ice extent in South America suggests that with projected future warming, the health of tropical glaciers could be in jeopardy, significantly impacting the communities and ecosystems that depend on them.Item Analysis and evolution of the ICT educational program in Colombia(2016-05) Daza Gomez, Miguel Felipe; Resta, Paul E.; Hughes, Joan EThis Master’s report represents the culmination of a study; wherein I set out to evaluate the evolution of the Information and Communication education policies in Colombia. I conducted the original self-study with a historical analysis of the technical policies in Colombia since 1930, tracing the connection between policymaking and the implementation of national educative programs. Based on primary sources from the Ministry of Education, Ministry of Information Technologies and Communications, Colombian National Development Plans, and the Decennial Plan of Education, I was able to identify changes in the Colombian legislation regarding the development of ICT education policies. The Colombian development of ICT education policies is an interesting case, as since in 1991 the educative system is decentralized meaning that municipal governments should be accountable of the adoption and integration of educative policies created by the Ministry of Education in Bogotá. The regional adoption of national policies is done through the strategic coordination between the Ministry of Education and the Regional Education Secretaries. This Master’s report presents a historical analysis that describes the socio-economic impact of ICT on the development of a knowledge-based society that supports economic growth in innovation and research. Continuously, is a historical description of the Colombian educative system, analyzing decisions made by policymakers to modernize the ICT infrastructure and teacher training in public schools to increase the quality of Colombian public education through the use of technology. The implementation of technology in public schools has been supported by the conjunct efforts of the Ministry of Education and Ministry of Information Technologies and Communication through the program “Computadores para Educar” (Computers to Educate). The program Computers to Educate had facilitated computers, tablets and teacher training to public schools across Colombia. An alliance between public and private sector had facilitated the creation of open-source content in the five Innovation Centers around the country, who creates the content for the national portal “Colombia Aprende”. This national portal facilitates content on science, language, math, and other areas to teachers and students. Colombian Policymakers had also utilized UNESCO ICT Competency Framework for Teachers to create an own competency framework for Colombian teachers.Item Campaigning with empty pockets : why the liberal party wins regional elections In Colombia(2010-08) Gamboa Gutierrez, Laura; Greene, Kenneth F., 1969-; Hunter, WendyIn the past decade, party systems have collapsed in Venezuela and Peru. Scholars have suggested that Colombia may be following a similar fate. I argue it is not. Despite loosing national elections the Liberal Party still wins subnationally. Regional clientelistic networks, based on goods that do not depend upon the central state, help provide votes to those candidates who have been in politics the longest. The latter are likely to be liberal politicians, with privileged positions within the party. They get nominated, thus, they have no reason to defect. Because they distribute goods that are independent from the national state, they also have little incentive to promote national candidates. Consequently, the LP wins within the regions but is unable to attain control of national offices. As long as it keeps doing so this party is unlikely to disappear.Item Careful crackdowns : human rights and campaigning on public security in Latin America(2012-05) Uang, Randy Sunwin; Hunter, Wendy; Weyland, Kurt; Dietz, Henry; Madrid, Raul; Greene, KennethCrime and violence are regularly seen as being ripe for politicians to turn into campaign issues and win votes. This study argues, in contrast, that success on public security is not so automatic: human rights values constrain the use of security and the winning of votes on it. Even in Latin American countries, where voters' concerns about rampant crime and violence are among the highest in the world, considerations of human rights combine with low trust in security forces to restrict the viability of the issue in key ways. Examination of presidential campaigns in Colombia in 1994, 1998, 2002, and 2010 supports this claim. Success on security is a two-step process: invoking the issue and then gaining voter support on the topic. Usability depends on the absence of recent repression and the degree of organization of security threats. Then, winning votes on it depends on having a civilian background, a campaign that balances security with other issues, and messages of careful enforcement. These messages of careful enforcement promise targeted, deliberate use of security forces' enforcement activities in a way that pays attention to human rights, rather than promising unbridled enforcement, increased punishment, or programs of long-term prevention. This study therefore shows how candidates are forced to walk a fine line between promising to establish order and promising to protect basic rights and liberties. These findings are powerful, providing an understanding of public security in electoral campaigns that maintains a much closer fit with empirical reality than existing research. The results also provide a critique of the sociological school of vote choice and points to ways in which ownership of the issue of security may be leased away. Furthermore, because the results are driven by the spread of human rights values, the results demonstrate the importance of quick shifts in political culture as a factor that explains changes in political patterns.Item Cenozoic structural evolution of the eastern margin of the Middle Magdalena Valley basin, Colombia : integration of structural restorations, low-temperature thermochronology, and sandstone petrography(2011-08) Sánchez, Carlos Javier, M.S. in geological Sciences; Horton, Brian K., 1970-; Mann, Paul; Ketcham, RichardStructural analysis of surface and subsurface data from the Middle Magdalena Valley basin and Eastern Cordillera fold-thrust belt to construct a kinematic model for its Cenozoic structural and stratigraphic evolution. The La Salina west-vergent thrust system marks the boundary between the Paleogene foreland basin of the Middle Magdalena basin and the Eastern Cordillera fold-thrust belt. New low-temperature thermochonological and sandstone petrographic analyses provide constraints on ages of thrust deformation and sediment dispersal. Apatite fission track (AFT) and U-Th/He thermochronological results show the timing of three structural events along the La Salina fault system: (1) late Eocene-early Oligocene (~43–35 Ma) initial hanging wall exhumation; (2) continued middle Miocene (~15 Ma) exhumation; and (3) continued but more rapid late Miocene (~12–3 Ma) hanging wall exhumation. Vitrinite reflectance results provide estimates of maximum burial depths for the hanging wall of the La Salina fault ranging from 4 to 6 km., this depth of burial estimates constrain the basin geometry during its late Eocene to late Miocene evolution. The eastern hanging wall of the La Salina fault displays a broad anticline-syncline pair affecting Cretaceous to Eocene strata with no significant faulting, whereas the western footwall contains a complex series of tight, thrust-related folds in Eocene-Quaternary strata. For foreland basin province, a proposed triangle zone accommodates a small amount of east-west shortening (< 1000 m) along the frontal thrust system by east-vergent backthrusting within a broader passive-roof duplex. East-west shortening in the Cenozoic stratigraphic section was also accommodated by detachment folding, which produced localized areas of steep dips. In the proposed kinematic restoration, the most recent phase of deformation represents out-of-sequence reactivation of the La Salina fault that is consistent with irregular crosscutting relationships of some footwall structures. Earliest exhumation by ~45–30 Ma in the Eastern Cordillera fold-thrust belt province matches (1) an increased proportion of sedimentary lithic fragments; and (2) a high degree of compositional maturity (Q88F4Lf8). Exhumation since ~15 Ma in the foreland province coincides with (1) the highest accumulation rates observed for the upper Miocene Real Group; and (2) a decrease in compositional maturity (Q55F8Lf36).Item Challenges and opportunities for the development of shale resources in Colombia(2013-12) Rodriguez Sanchez, Juan Camilo; Fisher, W. L. (William Lawrence), 1932-After the success of shale gas development in the United States, countries around the world are looking within their own territories for the possibility of replicating the U.S successes in order to achieve financial and/or energy security objectives. Such enterprise has shown to be not as easy as it might have been perceived to be. Some countries like Argentina, China and Poland, where large reserves of shale resources have been identified, have struggled to obtain beneficial results from their shale operations, with the result that even the more optimistic operators are now showing more caution and are reviewing everything before making any commitments to operate in countries with identified shale resources. Colombia, a country with strong oil and gas roots in its economic history, is actively attempting to attract operators to explore and produce their shale resources. If successful, these efforts have the potential to bring increased foreign investment to the country, while also improving Colombia’s oil and gas reserves, which have been declining over the last five years. This thesis, will address the challenges and opportunities of the development of shale resources in Colombia that operators will face by reviewing several critical aspects of the process. This thesis begins with a discussion of the geology of shale resources in Colombia, followed, first, by a review and analysis of the fiscal and contractual regime established in Colombia for the oil and gas industry, then, second, a risk analysis of possible Colombian shale operations, then third, a financial analysis of a possible shale project and, finally, ends with a summary of the challenges and opportunities an operator could face based on the analysis of the previous topics.Item The collective El Sindicato, 1976-1979 : intervening in conceptualism in Latin America(2011-05) Rodríguez, María Teresa, 1983-; Giunta, Andrea; Tarver, Gina M.Conceptual practices developed in Colombia towards the end of the 1960s and into the 1970s. Even a cursory look at surveys of Colombian conceptual art shows that the collective El Sindicato, active between 1976 and 1979, secured its space in these accounts with its 1978 work Alacena con zapatos, which won the top prize at the XXVII Salón Nacional. However, Alacena con zapatos was neither the only, nor the most significant, contribution of El Sindicato to the development of conceptual practices. The collective’s rich oeuvre, while concise, was nonetheless remarkable in its interventions on public spaces as a means for social change. A number of factors have led to the critical misunderstanding and, ultimately, the historiographical neglect of these interventions. This thesis problematizes these factors in order to reframe and expand El Sindicato’s role within the narrative of Colombian art. To elucidate El Sindicato’s contributions, and taking into account that much of Colombian conceptual art remains unknown in the United States, this thesis also registers Colombia’s artistic field as it stood in the 1970s. In all, my project situates El Sindicato’s practices within the broader narrative of Conceptualism as a means to both enrich our understanding of contemporary art in Colombia and help expand the familiar boundaries of the map of conceptual art.Item Education for the alleviation of poverty : a comparative study of conditional cash transfer programs to improve educational outcomes in Nicaragua and Colombia(2009-05) Stackhouse, Shannon Alexis; Lincove, Jane Arnold; Reyes, Pedro, 1954-The importance of education for individual well-being, social cohesion and economic growth is widely accepted by researchers and policymakers alike. Yet there exist vast numbers of people around the world, largely poor, who continue to lag behind wealthier people, often within their own nations. Conditional cash transfer programs were created to encourage investments in education and health by subsidizing their cost and changing household preferences. The programs increase short-term income as well as future wage potential, thus decreasing short-term and long-term poverty, as well as the poverty that is passed from generation to generation. Begun in Mexico and Brazil, the conditional cash transfer model is being replicated in many countries, but its replicability across socioeconomic and political contexts is far from clear. The present study adds to the research on conditional cash transfer programs through a comparative quantitative analysis of the effects of two programs on key educational outcomes in Nicaragua and Colombia. Using secondary panel data for the Nicaraguan Red de Proteccion Social and the Colombian Familias en Accion programs, a model reflecting demand constraints to education is used to determine the relative impacts of individual and household characteristics in the schooling decision, as well as to measure program impact in some of the most impoverished communities in the two countries. The empirical analysis is situated within a description of the historical, political and demographic contexts into which the programs were introduced. The results indicate that both programs increased enrollment and attendance, with lesser but still positive effects on retention. These effects were stronger for boys in Colombia, as was the importance of schooling expectations in determining enrollment. The study suggests that conditional cash transfer programs should be effective in other settings in which low educational attainment is caused largely by a lack of household resources.Item Ending civil war in Colombia(2015-05) Popa, Stoica Cristinel; Givens, Terri E., 1964-; Weyland, KurtCivil war is one of the most studied phenomena in political science. Its impact on human lives and economic development makes it one of the most destructive events known to mankind. Yet no scholarly consensus has emerged over what causes a civil war to be brought to a resolution. This master's report, relying on a case study of Colombia, shows that two of the most popular theories for explaining the continuation of civil war, the international context and the availability of drugs or other resources, are inaccurate. Instead, the continuation of civil war depends on the state's capacity to obtain military success against the armed groups and it's capability to guarantee the safety of the demobilized rebels. This report uses Weber’s concept of state capacity as the monopoly over the use of legitimate violence.Item Exile within borders : a study of complinace with the international regime to proetct internally displaced persons(2015-05) Cardona-Fox, Gabriel; Weaver, Catherine, 1971-; Hutchings, Robert L; Stolp, Chandler W; Elkins, Zachary S; Betts, AlexanderThe UN Guiding Principles for the Protection of Internally Displaced Persons (GP), introduced before the UN General Assembly in 1998, are the cornerstone of the international regime for the protection of internally displaced persons (IDPs). Much has been written about their unusual and unlikely development, yet very little is known about their effectiveness in altering state behavior towards their displaced populations. This dissertation takes a systematic and global look at patterns of commitment and compliance with the IDP regime and identifies forces that have driven states to comply with them. This dissertation addresses: (1) when and why countries voluntarily bind their sovereignty by instituting the GP into domestic law, and (2) if countries that have instituted the GP into law in fact comply with them. I tackle these questions using mixed methods. First, I present a large-n statistical analysis of all documented cases of displacement in the past twenty years to test the merits of competing theories of norm diffusion. Then I trace the evolution of Colombia’s response to internal displacement from denial of the crisis to deep compliance with the IDP regime. Both the first and second stages of the dissertation find that, above all, regional factors are key to the diffusion of IDP norms. This is evidenced by the clear pattern of regional clustering of commitment found in the statistical analysis and by the significant influence exerted by Latin American regional politics found in Colombia’s evolving response to its displacement crisis. This study should be of particular interest to policy practitioners and activists involved in addressing the problem of internal displacement and protecting the rights of IDPs.Item Foreland basin evolution and exhumation along the deformation front of the Eastern Cordillera, northern Andes, Colombia(2010-08) Bande, Alejandro Ezequiel; Horton, Brian K., 1970-; Ketcham, Richard A.; Steel, Ronald J.Tracking the phases of Cenozoic deformation in the Eastern Cordillera of Colombia has proven to be a challenging task. Clear disagreements remain in interpretations of the timing of uplift of the Eastern Cordillera, possibly based on difficulties in distinguishing first-cycle Central Cordillera grains from recycled Eastern Cordillera clasts. This thesis focuses on the Eocene-Pliocene sedimentary record of the eastern foothills of the Eastern Cordillera at a latitude of 6°N, integrating basin analysis with several provenance techniques in order to date the activation of several thrust systems. Based on assessments of depositional environments and sediment dispersal patterns together with mineralogical and geochronological provenance, the onset of uplift in the axial zone of the Eastern Cordillera is constrained to be Oligocene. Prior to uplift, deposition in the eastern foothills was sourced from the eastern craton. Following the Oligocene episode, a continuous eastward advance of deformation is documented. An early Miocene episode probably reactivated the easternmost Cretaceous rift boundary along the eastern side of the Eastern Cordillera. Subsequent footwall shortcuts of those faults initiated activity in the middle to late Miocene, creating an intermontane (piggyback) basin in the eastern foothills at that time. In the preferred interpretation, this in-sequence history of thrust activation represents the main phases of deformation in the Eastern Cordillera from Eocene to Pliocene time, with neotectonic activity recording continued shortening.Item Guild-specific responses of birds to habitat fragmentation : evaluating the effects of different coffee production systems in Colombia(2011-12) LaRota-Aguilera, Maria Jose; Young, Kenneth R.; Miller, JenniferHabitat loss and fragmentation are the main drivers of biodiversity loss, especially in the tropics, where the transformation of forested areas into agriculture is predicted to increase dramatically in the next five decades. Although several studies have elucidated the negative impacts of agriculture on biodiversity, recent work suggests that some agro-ecosystems, such as coffee plantations, are potential key environments for maintaining biodiversity and ecosystem services. This study evaluated the role of different coffee production types (sun-exposed, semi-shade and shade in polycultures or monocultures) on the bird communities associated with these agro-ecosystems in the tropical Andes of Colombia. It used a guild-specific approach and nonparametric statistical methods to identify the influence of particular environmental, ecological and landscape variables on the bird community assemblage and to assess potential changes in the species composition among management type. The potential responses of avifauna to fragmentation were studied from three different perspectives: i) from a patch-level point of view, evaluating the effect of local habitat factors (e.g. canopy cover, type of crop and crop management type); ii) from a species point of view, evaluating the role of species ecological traits (e.g. feeding habitat); and iii) from a landscape point of view, evaluating the effect of landscape configuration variables (e.g. patch area and perimeter length). The results indicated that polyculture and shade coffee crops host the most diverse avian communities and that guild representativeness varied among different coffee crop types. The type of coffee production type and the habitat characteristics associated with them seemed to have the greatest influences on families such as flycatchers, hummingbirds and wrens. Finally, coffee plantations can potentially contribute to the maintenance of bird diversity in anthropogenic landscapes; however these benefits are strongly influenced by the type of crop management. The maintenance of traditional coffee production (shade polyculture coffee) is recommended, and should be economically and socially encouraged.Item Heritage tourism in Latin America : cultural routes and the legacy of Simón Bolívar in Colombia, Ecuador and Venezuela(2011-05) McQueen, George Genung; Sletto, Bjørn; Holleran, MichaelHeritage tourism is one of the fastest growing sub-categories of the tourism industry, which is arguably the largest industry in the world. When communities and regions compete for a greater share of the heritage tourism market, the authenticity and integrity of a heritage can be compromised by the way it is represented. One way to represent heritage is a “cultural route,” which has recently been added to definition of “cultural heritage” in the UNESCO World Heritage Convention. The interpretation of a “cultural route,” however, continues to evolve, especially in Latin America. In anticipation of the bicentennial celebration of independence from Spain, two cultural routes were separately inaugurated in 2009: the Ruta del Libertador in Ecuador and Venezuela, and the Ruta Libertadora in Colombia. After providing an overview of the historical, political and cultural contexts that surround these routes, this paper draws upon a website content analysis to explores how national identity, cultural heritage and the legacy of Simón Bolívar are represented by the governments of Colombia, Ecuador and Venezuela. These observations and analyses show that while both routes represent a shared heritage, the differences in their representations straddle the definitions of “authenticity” and “cultural heritage,” as the Ruta Libertadora in Colombia is a “cultural route” and the Ruta del Libertador in Ecuador and Venezuela is a “cultural tourism route.” However, when considered together, the Ruta del Libertador and Ruta Libertadora are a cultural route that more accurately represents a crucial moment in Latin American history: the liberation of South America from Spain, led by Simón Bolívar, “El Libertador.”Item Ideal justice in Latin America : interests, ideas, and the political origins of judicial activism in Brazil and Colombia(2010-08) Nunes, Rodrigo Marinho; Weyland, Kurt Gerhard; Brinks, Daniel; Elkins, Zachary; Hunter, Wendy; Jacobsohn, GaryWhat are the causes and consequences of judicial empowerment? What motivates the political decision to delegate authority to independent judiciaries, and what explains the subsequent behavior of these institutions? Going against current trends in comparative judicial politics, this dissertation answers these questions by taking ideas seriously. Dominant accounts of judicial empowerment and behavior associate the emergence of rights protecting judiciaries with the actions of powerful political actors concerned with the protection and promotion of their political self-interests. In contrast, my analysis of Brazil and Colombia links the emergence of such institutions to the actions of groups and individuals who subscribe to the principled belief that courts should focus their efforts on the protection and promotion of constitutional guarantees. These ideational carriers use their resources to convince institutional designers of the suitability of their proposals, and exert powerful influence over the institutional outcome of constitutional transitions. These actors also influence the actions of newly empowered courts to the extent that they are able to entrench their ideational allies on the bench during the uncertainty of the transition. These findings contradict the arguments that judicial empowerment is designed to weaken electoral opponents or to insulate the political process from popular pressures, and that judges are rational-strategic actors whose main concern is to protect their institutional integrity.Item Institutionalized amnesia : the (mis)representation of paramilitarism in Colombia(2013-05) Pérez-Santiago, Mariel Patricia; Polit Dueñas, GabrielaColombian state and non-state actors are engaging in an important conceptual debate concerning the nature of a "new" type of armed group in the country. The state labels these groups "BACRIM" (criminal gangs), arguing that they are actors of organized crime. Members of civil society reject the state's conceptualization, arguing that these groups are paramilitaries operating in the context of the armed conflict. These organizations explain that "new" groups commit the same systematic human rights violations and adhere to the same modus operandi as the Autodefensas Unidas de Colombia, an umbrella organization of over 30,000 paramilitaries that the government supposedly demobilized in a 2005 negotiation. The state, in turn, argues that paramilitarism no longer exists in Colombia and that these "new" groups do not adhere to the counterinsurgent political ideology that was characteristic of paramilitarism. My research project is a nuanced analysis of the Colombian state and non-state debate concerning these "new" armed groups. I combine interviews with state and civil society representatives with historical contextualization in order to understand what is at stake in the positions that both sides are aggressively fostering in the debate. In conceptualizing these "new" groups, many key informants engaged in a renegotiation of the state-formed historical memory concerning paramilitarism. An analysis of the trajectory of paramilitary activity reveals the protection of important elite economic and political interests as the driving force of paramilitarism; this paramilitary project fits within the goals of a state-sponsored economic process of capital accumulation. In utilizing the paramilitary label, civil society highlights these as the structural causes of paramilitarism. The state, in turn, attempts to cement its simplified definition of paramilitarism as a counterinsurgency project in removing the term 'paramilitary' from the official discourse. Furthermore, in erasing paramilitarism from the discourse, the state attempts to disassociate itself with a dark history of human rights violations against civilians. To fully understand the debate in Colombia is to understand more generally the power and weight of words in denouncing or, conversely, in silencing important issues of human rights and, ultimately, in accurately or inaccurately constructing historical memory of armed conflict.Item A lack of power(2011-05) Sánchez, Alejandro, 1979-; Goodman, Mark, 1946-; Reynolds, AnnThis graduate report, more than a formal description of the artistic developments I have gradually acknowledged, is a personal and perhaps arbitrary recollection of ideas that might help the reader–and me–understand the nature of the gestures that have evidently influenced the work I have produced in the past two years. These words belong to an inevitable act of introspection that seeks to validate some of the questions that have directed my artistic investigation throughout this time. I believe my work derives from two different and yet relevant positions: on one hand, the need to find meaning out of brutal events that have indisputably marked the course of history, specially in Colombia–my home country–where victims appear to loose their voices in a context ruled by indifference and apathy; and, on the other, the desire to understand what controls the reception of violent imagery as we depend on how social location, collective identification and political affiliation dictate the way we perceive the world. Each project mentioned in this report is a result of studying obsessively the political kidnappings that have been taking place in Colombia in the past twenty years, as a response to an allegedly abuse of power induced by the government against Las FARC, one of the most powerful guerrilla groups in Latin America. However each one is far from being a true document of real events and on the contrary, each one emerges as a naïve interpretation, possibly an illustration, of an ambiguous conflict that has no reasonable explanation but being a natural product of a conservative warfare–which in fact is no less than a reading made by a distant and passive witness like myself.Item Municipal performance: does mayoral quality matter?(2009-05-15) Avellaneda, Claudia NancyThis research addresses the question of what explains municipal performance in terms of delivering social services and fiscal performance. While the existing literature explains governmental performance with political, institutional and socio-demographic factors, I suggest that the greatest influence on municipal performance comes from having qualified managers. Specifically, I argue that that mayoral qualifications influence municipal performance. By qualifications I mean mayors? human capital, that is, their educational and job-related experience. The rationale for my proposition rests on the fact that in developing municipalities the mayor is not just the elected leader but also the public manager, as s/he performs not just political but also administrative functions. Under certain circumstances, however, mayoral qualifications may not have the same influential power on municipal performance. Therefore, I also argue that in unfavorable municipal contexts, the potential influence of mayoral qualifications on performance decreases. I use both statistical and survey-experimental methodologies to test the hypotheses derived from the proposed ?mayoral quality theory.? I collected six years of data for the statistical analyses by doing field research across the 40 municipalities that comprise the Colombian Department of Norte of Santander. For the surveyexperimental analysis, I gathered data from interviews and surveys with 120 mayors from 12 Latin American countries, who participated in the II Latin American Congress of Cities and Local Governments held in Cali, Colombia, on July 26-29, 2006. The statistical findings reveal that mayoral qualifications?education and jobrelated experience?positively influence municipal performance with respect to education enrollment, tax property collection, and social program investment. However, the positive impact that mayoral qualifications have on such performance indicators decreases under external constraints, such as the presence of illegal armed groups. From the survey-experimental study, findings show that issue salience (or nature of municipal need) moderates the impact that mayoral qualifications have on mayors? decision-making. In education issues, for example, qualified mayors are more likely to perform better, while in infrastructure issues they are less likely to do so.Item The other side : an alternate approach to the narconarratives of Bolivia, Colombia, and Brazil(2015-05) Jackson, Dorian Lee; Leu, Lorraine; Polit Dueñas, Gabriela; Afolabi, Ominiyi; Domínguez-Ruvalcaba, HéctorThe dissertation examines novels that represent new spaces and agents of the drug trade, that re-map the trade across Latin America, and that raise questions regarding how narcotrafficking creates moral and ethical crises among people from different social classes. The corpus of literature examined includes the works of ten authors from the three countries. Juan de Recacoechea, José Wolfango Montes Vanucci, Homero Carvalho Oliva, and Tito Gutiérrez Vargas are Bolivians and write from three regions in the country. Alison Spedding is the only foreign-born author writing novels about the Bolivian drug trade included in the analysis. Darío Jaramillo Agudelo and Juan Gabriel Vásquez represent the Antioquia and Bogotá departments of Colombia. Rubem Fonseca, Patrícia Melo, and Marçal Aquino write from the cities of Rio de Janeiro and São Paulo in Brazil. Within these novels, I examine mid-level roles of the illegal drug trade, those that have remained invisible in the mainstream representations. The levels of participation portrayed in the works range from urban, middle and upper class workers to land owners of the Bolivian countryside. My emphasis on the implications of these less spectacular roles shows that the moral decay, lack of values, and the consumer frenzy are not exclusive of the poor. The upper classes are driven by the same ambitions to access the money of the drug trade. In order to reconsider the use of narcofiction as an effective tool for narrating the realities of the illegal drug trade, I propose a reading of how the power and influence of narcotrafficking expose a lack of scruples in the search for financial gain on the part of what I call mid-level participants. Such a term helps me give visibility to the actions of these characters that are so needed in the business: money launderers, corrupt police officers, drug mules. This reading makes it possible to also consider the issues of culpability and impunity and the social and political divisions which are created to maintain these structures.Item Paleogene sedimentation patterns and basin evolution during Andean orogenesis, Middle Magdalena Valley basin, Colombia(2010-08) Moreno, Christopher John; Horton, Brian K., 1970-; Steel, Ronald J.; Milliken, Kitty L.The Central Cordillera and Eastern Cordillera of the northern Andes form the western and eastern flanks of the north-trending Middle Magdalena Valley basin. Previous estimates for the timing of initial exhumation of the two cordilleras range from ~100 to ~10 Ma. Accurately constraining the spatial and temporal distribution of deformation in Colombia has implications for the shortening history of the Andean convergent margin and the prediction of rapid lateral facies changes in sedimentary basins in close proximity to sediment sources. This study applies sandstone petrographic point counts, field sedimentological analyses of basin fill, and paleocurrent measurements of trough cross-stratification, clast imbrication, and flute casts to provide new insights into the tectonic history of the flanks of the Middle Magdalena Valley basin. Between the lower and upper Paleocene strata of the Lisama Formation, paleocurrent orientations show a shift from northward to eastward transport. This change in sediment dispersal coincides with a shift from a cratonic (Amazonian) to orogenic (Andean) sediment source, as recorded by published U-Pb detrital zircon geochronological results (Nie et al. 2010), suggesting initial uplift of the Central Cordillera by mid-Paleocene time. Later in the basin’s history, establishment of an alluvial-plain system with meandering-channel deposits is recorded in lower–middle Eocene strata of the lower La Paz Formation. Consistent eastward paleocurrents characterize mid-Paleocene through uppermost Eocene strata, indicating a continuous influence of western sediment source areas. However, within the upper middle Eocene succession (~40 Ma), at the boundary between the lower and upper La Paz Formation, sandstone compositions show a dramatic decrease in lithic content. This compositional change is accompanied by a facies shift to amalgamated fluvial channels, reflecting changes in both the composition and proximity of the western sediment source. We attribute these changes to the growing influence of the exhumed La Cira/Infantas paleohighs off the western flank of the present-day Nuevo Mundo syncline. In the uppermost Eocene strata of the Esmeraldas Formation, paleocurrents show a switch to dominantly westward transport that persisted through the Neogene. In addition, deposits show a contemporaneous decrease in the amount of coarse-grained channel deposits. These changes are interpreted to reflect the onset of exhumation in the Eastern Cordillera. The lack of a significant change in sandstone compositions at this boundary suggests a compositional similarity between strata uplifted by the Lisama structure and the Eastern Cordillera. These data support and further refine previous thermochronologic and provenance studies which suggest that uplift-induced exhumation of the Central Cordillera and Eastern Cordillera commenced by mid-Paleocene and late Eocene–early Miocene time, respectively.Item Protecting “water refugees” : an examination of alternative frameworks for protecting those displaced by water scarcity, water policy, and water management(2011-08) Jenkins, Anjela Nicole; Dulitzky, Ariel E.; Brinks, Daniel M., 1961-The increasing frequency and/or severity of climate-related disasters has pushed “environmental refugees” onto center stage, capturing headlines the world over. Although the urgency implied by the “refugee” terminology is apt, the legal reality is that few “environmental refugees” can enjoy the protections of refugee law—a system of law that was created in the post-World War II era to respond to the ongoing needs of Jews displaced during the War and whose stringent requirements reflect the particular historical moment of its creation. Despite evolutions in other areas, refugee law does not typically provide recourse for environmental harms. By contrast, human rights law, at both the international and domestic levels, has continued to evolve to recognize environmental and social environmental rights; for example, the General Assembly of the United Nations in 2010 recognized a human right to water. Issues related to water scarcity or water (mis)management may already be causing affected individuals to leave their homes, and concerns about water availability in the near future necessitate the development of legal tools for protecting these populations. This paper draws on human rights law, as it exists in the international system and as applied in Colombia, to create a framework that may provide greater protection for so-called “water refugees,” given the increasing salience of displacements related to water, the lack of movement in refugee law regarding environmental displacements, and the promise of social and economic rights discourse.
