The major concern of this study is an attempt to analyze the attitudes.of Henry Clay, United States Congressman and Senator from Kentucky, 1807-1852, and three time presidential candidate, concerning the institution of slavery by examining its effects upon his political career from 1798 to 1850. The major conclusions of this study are that early in his life Clay made an intellectual commitment that slavery was wrong and maintained this abstract view of the institution until his death. However, Clay never took an active stand against slavery for three reasons: he believed that an antislavery stand would destroy his political career; he realized the explosiveness of the slavery issue as early as 1799, and his misguided love for the Union forced him to attempt to suppress the issue; and Clay was a racist who did not wish to see the United States populated with a sizable number of free blacks.

The role of political discourse in the communication of security issues is fundamental to the Copenhagen School’s framework of securitization. In their work, Security: A New Framework for Analysis (1998), the Copenhagen School set out to challenge traditional International Relations theory by questioning the primacy of state-centric approaches that narrowly focus on military aspects of security. Whilst broadening the areas of security to include economic, societal, political and environmental threats, they also proposed that threats are articulated through the “speech acts” of mainly political elites. By signaling threats discursively via “securitizing moves”, political elites inform the audience of the existence of security threats. However, the Copenhagen School fails to address the political partiality of such pronouncements. The focus of this analysis is to examine the persuasive discursive practices employed by political elites to encourage audience consent with a specific focus on political elite portrayals of inward migration in relation to security. In their work, “Identity, Migration and the New Security Agenda in Europe” (1993), the Copenhagen School outlined a nexus between security and transnational migration within a Western context. Using content analysis and critical discourse analysis methods, this analysis will provide a comparative cross-national study of how migration is constituted as a security threat. By analysing political elite discourse as presented in speeches and as recontextualised in media portrayals in two major South East Asian receiving countries, Malaysia and Singapore, this thesis assesses the applicability of the Copenhagen School approach in alternative locations. Adopting a thematic approach, it examines how migrants are depicted via political discourse as threats to societal, economic and political security and how the feminization of migration in recent years has been depicted as a security challenge. A cross-national comparison of political discourse relating to the migrant/security nexus reveals not only how discursive formulations of security by political elites are constructed in order to legitimise policy and practices, but how similar issues may be addressed differently. Both Malaysia and Singapore have a long history of immigration, which is reflected in their diverse multi-ethnic, multi-racial and multi-cultural societies. Geographically co-located and with a shared historical legacy, both have become increasingly dependent on migrant labour to support economic growth and receive relatively large intakes of migrants from neighbouring countries. Yet, there are significant differences in how migrants are depicted in relation to security. Challenges are proposed to the framework that the Copenhagen School propounds. Moreover, I contend that the constructed nature of political discourse allows the potential for a more nuanced and normative discourse that could desecuritize migration and focus more positively on its benefits and upon alternative non-elite perspectives of security.

Dans le contexte actuel d’accroissement de la population mondiale, il est nécessaire de construire d’avantage d’infrastructures pour répondre à la pression industrielle grandissante. Ces constructions se font principalement sur la mer comme les ports, les îles artificielles ou encore les logements touristiques. Le béton est le matériau majoritairement utilisé en raison de son faible coût de production mais aussi de sa résistance à l’eau de mer. Comme tout matériau immergé en milieu marin, le béton est colonisé par les organismes vivants, devenant ainsi support de leur développement. Cependant, l’eau de mer est un milieu particulièrement agressif vis-à-vis des matériaux cimentaires ; des dégradations physiques, chimiques et biologiques sont observées dans le temps. Les deux premiers types de dégradation sont particulièrement bien documentés par la communauté scientifique. En revanche, les dégradations biologiques sont peu étudiées. L’objectif de cette thèse est donc de tout d’abord mettre en place un dispositif expérimental en laboratoire, permettant la colonisation d’un matériau cimentaire par des microorganismes. Des outils pertinents pour caractériser le biofilm sur le matériau ont été choisis après une étude bibliographique, dans le but de mieux comprendre la cinétique de colonisation. Des analyses chimiques du matériau ainsi que de l’eau de mer artificielle ont été effectuées à échéances régulières pour évaluer les actions du biofilm sur le matériau cimentaire. Différents matériaux ont été formulés pour étudier l’impact de la formulation sur la colonisation. / In the current context of increased world population, it is necessary to built more infrastructures to meet the increasing industrial pressure. These constructions are erected on the sea as harbors, artificial islands or tourist accommodation. Concrete is mainly used because of its low-cost and durability in the marine environment. Like any material immersed in seawater, concrete is colonized by living organisms, becoming an habitat for their development. However, seawater is a very aggressive environment towards cementitious materials; physical, chemical and biological degradations are observed with time. Nowadays, physical and chemical degradations are well understood and reported in the literature but there is a lack of knowledge concerning biological effects. The aim of this thesis is first develop an experimental device in laboratory, allowing the colonization of cementitious material by microorganisms. Relevant tools to characterize the biofilm on the material were chosen to better understand colonisation’s kinetic. Chemical analysis of material and seawater were made to evaluate the actions of the biofilm on cementitious material. Different materials were produced to study the impact of the formulation on the colonization.

This dissertation provides a history of the white supremacist police-state in Nairobi beginning with the excursions of European-led caravans and ending with the institutionalizing of the municipal entity known as the township of Nairobi. It argues that the town was not an entity in which white supremacist and colonial violence occurred but that it was itself an effect white supremacy. It presents the invasion of whiteness into the Nairobi region as an invasion of a new type of power: white supremacist police power. Police power is reflected in the flogging of indigenous peoples by explorers, settlers and administrators and the emergence of new institutions including the constabulary, the caravan, the “native location” and the punitive expedition. It traces the transformation of the figure of the indigenous other as “hostile native,” “raw native,” “native,” “criminal-African” and finally “African.” The presence of whiteness, the things of whiteness, and bodies racialized as white in this settler-colonial society were corrosive and destructive elements to indigenous life and were foundational to the construction of the first open-air prison in the East African Hinterland.

The Philippines lies at the intersection of two global empires, having been under Spanish colonial rule from 1521-1898 and American colonial rule from 1899-1945. As a country that expresses a melange of cultures, both on the global and local level, Filipino national identity is constantly in debate. This thesis examines how literature in the Philippines can play a role in establishing a national identity in relation to the ways in which Filipinos of both the home country and the Filipino diaspora negotiate language. Analyzing José Rizal’s Noli Me Tangere (1887) alongside Jessica Hagedorn’s Dogeaters (1990) through the theoretical framework of the contact zone, a rejection of the third space, and deterritorialization shows that Filipino culture consumes imposing foreign cultures, dismantling even their label as foreign. Thus, the interaction between Filipino culture and colonial culture is a rich example of how to decentralize the Western gaze in postcolonial literary analysis.

Pierce’s disease (PD) of grapevines, caused by Xylella fastidiosa, is devastating Texas vineyards. Two rapid diagnostic techniques, real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA), were compared on the basis of cost, reliability, and their ability to quantify X. fastidiosa in diseased tissues. A high correlation was found between the two techniques for measuring bacterial titer in vitro. A similar relationship was not detected when applying the methods to diseased tissue. There was a 75% similarity between the techniques when used to diagnose PD in artificially infected grapevines. Where the two methods differed, real-time PCR was more successful in identifying plants known to be infected with the bacterium. In uninoculated grapevines, the two techniques were similar, where the positive rates were 7% and 4% for ELISA and real-time PCR respectively. In a second study, 3 grape cultivars, ‘Cynthiana’, ‘Cabernet Sauvignon’, and ‘Chardonnay’, were inoculated with 2 isolates of X. fastidiosa to measure disease development and colonization by the pathogen. The bacteria colonized similar distances from the inoculation point over a 25 week period in all three cultivars. Real-time PCR and ELISA absorbance values suggest that the concentrations of bacteria ranged between 104 and 106 cells/ml in a 1.27 cm section of grapevine cane. Concentrations of bacteria didn’t vary based on distance from the inoculation point. Marginal leaf-scorch symptoms were seen on ‘Cabernet Sauvignon’ and ‘Chardonnay’ grapevines 9 weeks post-inoculation. Leaf-scorch symptoms were not observed on ‘Cynthiana’. The vigor of all inoculated grapevines was reduced compared to negative control grapevines the season after initial infection. In a third study, a Texas vineyard planted in Viognier grapevines was surveyed for PD symptoms on 3 separate dates. In October 2003, 45/50 rows had significant aggregation of symptomatic grapevines according to Ordinary Runs Analysis. Aggregation of symptomatic grapevines was found down the row more often than across the row. The rapid rate of disease progress and mortality rate of vines in this vineyard suggest that vine-to-vine spread is occurring and that Viognier vines are highly susceptibly to PD.

This project examines the articulation and application of colonial law in the French colony of Martinique during the eighteenth century through the work of a legal commentator and colonial magistrate, Pierre Dessalles. His compilation of Martinican laws reveals how local elites applied laws usually promulgated in France. His reliance on European political theorists illustrates the dissemination of legal knowledge across the Atlantic, while his comments and explanation of colonial law in light of Martinique’s history anchor this discussion in a local history. Thus, from Dessalles’ creole, local elite perspective, historians can perceive both the operation and ideology behind Martinican law because this document explicitly presented law (as prescription) and legalities (as practice) together. / text
