Silence by Stealth: Freedom of the Press and Polarization in Latin America

The weak democratic systems that followed decades of military dictatorships in Latin America coupled with the emergence of new authoritarian regimes of the left have had a significant impact on the relationships between the governments and the media. The new populist leaders have challenged the media that have generally reflected the perspectives of the traditional elites. This ideological clash has renewed direct and indirect censorship, curtailing freedom of expression and thus, freedom of the press. In this context, this paper discusses the mechanisms used by Latin American governments, particularly the new authoritarianism of the left, to silence dissident voices. Many of these mechanisms are legal, found in laws related to personal injury and defamation. Others have been of constitutional nature, invoking states of emergency or national security concerns. Some governments have used institutional means to close down newspapers and other sources of information. Current media conditions in Latin America show growing polarization. This has led to considerable levels of violence and intimidation against editors, journalists, and news crews in several countries. It is precisely this type of deterioration of fundamental rights that leads to questioning the strength and sustainability of Latin American democracies.

Effect of water on olivine single crystals plasticity, deformed under high pressure and high temperature

The Earth's upper mantle, mainly composed of olivine, is seismically anisotropic. Seismic anisotropy attenuation has been observed at 220km depth. Karato et al. (1992) attributed this attenuation to a transition between two deformation mechanisms, from dislocation creep above 220km to diffusion creep below 220km, induced by a change in water content. Couvy (2005) and Mainprice et al. (2005) predicted a change in Lattice Preferred Orientation induced by pressure, which comes from a change of slip system, from [100] slip to [001] slip, and is responsible for the seismic anisotropy attenuation. Raterron et al. (2007) ran single crystal deformation experiments under anhydrous conditions and observed that the slip system transition occurs around 8GPa, which corresponds to a depth of 260Km. Experiments were done to quantify the effects of water on olivine single crystals deformed using D-DIA press and synchrotron beam. Deformations were carried out in uniaxial compression along [110]c, [011]c, and [101]c, crystallographic directions, at pressure ranging from 4 to 8GPa and temperature between 1373 and 1473K. Talc sleeves about the annulus of the single crystals were used as source of water in the assembly. Stress and specimen strain rates were calculated by in-situ X-ray diffraction and time resolved imaging, respectively. By direct comparison of single crystals strain rates, we observed that [110]c deforms faster than [011]c below 5GPa. However above 6GPa [011]c deforms faster than [110]c. This revealed that [100](010) is the dominant slip system below 5GPa, and above 6GPa [001](010) becomes dominant. According to our results, the slip system transition, which is induced by pressure, occurs at 6GPa. Water influences the pressure where the switch over occurs, by lowering the transition pressure. The pressure effect on the slip systems activity has been quantified and the hydrolytic weakening has also been estimated for both orientations. Data also shows that temperature affects the slip system activity. The regional variation of the depth for the seismic anisotropy attenuation, which would depend on local hydroxyl content and temperature variations and explains the seismic anisotropy attenuation occurring at about 220Km depth in the mantle, where the pressure is about 6GPa. Deformation of MgO single crystal oriented [100], [110] and [111] were also performed. The results predict a change in the slip system activity at 23GPa, again induced by pressure. This explains the seismic anisotropy observed in the lower mantle.

An analysis of Venezuela's foreign policy during the period of the Betancourt doctrine and Caldera's ideological pluralism

This thesis examines the foreign policy of Venezuela during the period of the Betancourt Doctrine (1945-1948 and 1959-1963), and Caldera's Ideological Pluralism (1969-1973). The study seeks to determine whether, and to what extent the pursuit of political and economic interests and ideology determined Venezuela's foreign policy. Based on primary and secondary sources, this study examines political economy and ideology and how these affected the outcome of Venezuela's foreign policy. The major finding of this thesis is that Venezuelan foreign policy was a pragmatic one but it was rationalized within an ideological framework. In fact, Venezuela was most concerned in pursuing its domestic economic and political interests but these were hidden behind an ideological facade.

Evidence of climate variability and tropical cyclone activity from diatom assemblage dynamics in coastal southwest Florida

Estuaries are dynamic on many spatial and temporal scales. Distinguishing effects of unpredictable events from cyclical patterns can be challenging but important to predict the influence of press and pulse drivers in the face of climate change. Diatom assemblages respond rapidly to changing environmental conditions and characterize change on multiple time scales. The goals of this research were to 1) characterize diatom assemblages in the Charlotte Harbor watershed, their relationships with water quality parameters, and how they change in response to climate; and 2) use assemblages in sediment cores to interpret past climate changes and tropical cyclone activity. ^ Diatom assemblages had strong relationships with salinity and nutrient concentrations, and a quantitative tool was developed to reconstruct past values of these parameters. Assemblages were stable between the wet and dry seasons, and were more similar to each other than to assemblages found following a tropical cyclone. Diatom assemblages following the storm showed a decrease in dispersion among sites, a pattern that was consistent on different spatial scales but may depend on hydrological management regimes. ^ Analysis of sediment cores from two southwest Florida estuaries showed that locally-developed diatom inference models can be applied with caution on regional scales. Large-scale climate changes were suggested by environmental reconstructions in both estuaries, but with slightly different temporal pacing. Estimates of salinity and nutrient concentrations suggested that major hydrological patterns changed at approximately 5.5 and 3 kyrs BP. A highly temporally-resolved sediment core from Charlotte Harbor provided evidence for past changes that correspond with known climate records. Diatom assemblages had significant relationships with the three-year average index values of the Atlantic Multidecadal Oscillation and the El Niño Southern Oscillation. Assemblages that predicted low salinity and high total phosphorus also had the lowest dispersion and corresponded with some major storms in the known record, which together may provide a proxy for evidence of severe storms in the paleoecological record. ^

La caída del hombre nuevo: Narrativa cubana del “Período Especial”

The purpose of this dissertation is to demonstrate that the societal changes that took place in Cuba during the last decade of the twentieth century, period know as The Special Period in Times of Peace, created the necessary conditions for the development of a new type of narrative. The first chapter constitutes an historical overview of the role of the State in the literary and artistic creation in revolutionary Cuba. The second, third, and fourth chapters analyze the major characteristics in the narrative of this period, creating a contrast with previous decades of the revolutionary era. With such purpose the study is divided into three categories: language, themes, and ideology. The usage of language as a means of transgression, the recurrence of the topic of need, and the rebirth of critical thinking, represent the principal characteristics of this literary period, and confirm the main idea of this dissertation: the fall of the ideal of the New Man. The final chapter summarizes the findings of the study and poses a question: If the ideal of the New Man has ceased to exist, what has replaced it? The question of whether or not a new ideal has replaced that of the New Man, and what that ideal might be, constitutes a stepping-stone for further studies in the area of Cuban narrative of the Special Period and beyond.

Marxists into Muslims: The Iranian irony

This dissertation examines the influence of Islamic ideology on Iranian Marxists during the 1979 revolution. The purpose of this study is to extricate the influence of Islamic culture, ideology, and terminology on Marxist organizations and on individuals who identified themselves as Marxists in Iran. This is especially of interest since in many ways Marxism and Islam are ideologically in conflict. Were Marxists aware of the influences of Islam in their behavior and ideology? To investigate the irony publications put forth by several Marxist organizations before and after the 1979 revolution were examined. A history of such influence both ideologically and contextually is depicted to demonstrate their political and cultural significance. Through the study of Marxist political organs, theoretical publication and political flyers distributed during and after the revolution, the phenomenon of Marxists converting to an Islamic ideology became clearer. Many Marxist organizations were demonstrably utilizing Islamic political ideology to organize and mobilize masses of Iranians. This study shows a historical precedence of Marxists’ usage of Islam in the political history of Iran dating back to early twentieth-century. Primary and secondary Marxist literature showed that Islam was an inescapable social and political reality for Iranian Marxists. Not only was there a common upbringing but a common enemy fostered provisional collusion between the two. The internalizing the idea of martyrdom—of Shi’a Islam—was a shared belied that united Marxists with Muslins in their attempt to effect sociopolitical change in Iran. Studying Marxist publications shows evidence that many Iranian Marxists were not conscious of using Islamic ethics and terminology since Islamic beliefs are part of the taken-for-granted world of Iranian culture. This contextual belief system, pervasive within the culture and a change of political ideology is what created the conditions for the possibility of Marxists becoming Muslims.

"To hold the world in contempt": The British Empire, war, and the Irish and Indian nationalist press, 1899–1914

The era between the close of the nineteenth century and the onset of the First World War witnessed a marked increase in radical agitation among Indian and Irish nationalists. The most outspoken political leaders of the day founded a series of widely circulated newspapers in India and Ireland, placing these editors in the enviable position of both reporting and creating the news. Nationalist journalists were in the vanguard of those pressing vocally for an independent India and Ireland, and together constituted an increasingly problematic contingent for the British Empire. The advanced-nationalist press in Ireland and the nationalist press in India took the lead in facilitating the exchange of provocative ideas--raising awareness of perceived imperial injustices, offering strategic advice, and cementing international solidarity. Irish and Indian press coverage of Britain's imperial wars constituted one of the premier weapons in the nationalists' arsenal, permitting them to build support for their ideology and forward their agenda in a manner both rapid and definitive. Directing their readers' attention to conflicts overseas proved instructive in how the Empire dealt with those who resisted its policies, and also showcased how it conducted its affairs with its allies. As such, critical press coverage of the Boxer Rebellion, Boer War, Russo-Japanese War, and World War I bred disaffection for the Empire, while attempts by the Empire to suppress the critiques further alienated the public. This dissertation offers the first comparative analysis of the major nationalist press organs in India and Ireland, using the prism of war to illustrate the increasingly persuasive role of the press in promoting resistance to the Empire. It focuses on how the leading Indian and Irish editors not only fostered a nationalist agenda within their own countries, but also worked in concert to construct a global anti-imperialist platform. By highlighting the anti-imperial rhetoric of the nationalist press in India and Ireland and illuminating their strategies for attaining self-government, this study deepens understanding of the seeds of nationalism, making a contribution to comparative imperial scholarship, and demonstrating the power of the media to alter imperial dynamics and effect political change.
