Nickel silicate laterite deposits developed on ultra-mafic rocks are similar in many general respects but they vary considerably in detail. The mineralogy of these surficial deposits is very complex and difficult to determine because of the fine grained nature and solid solution characteristics of the hydrous secondary minerals and because many of the phases are actually mineraloids that are poorly ordered or amorphous. To try some new approaches toward clarification of these phases, 24 samples from New Caledonia and Puerto Rico ranging from the ophiolite-ultramafic olivine-pyroxene-chromite-serpentine substrate rocks upward through intermediate phases of weathering to the final oxide -hydroxide iron cap phase were analyzed with the infrared spectrophotometer (IR -10) and with the automated X –ray diffractometer. Four limonite samples were also mineralogically analyzed. Goethite, secondary quartz, cryptomelane, hematite, chromite, talc, thuringite, and garnierite have been identified in various samples as weathering profile products.

Exemplary of a widespread, regional phenomenon that begins at mid-century, writers such as Aimé Césaire and George Lamming take up certain texts such as Shakespeare's The Tempest and recast them in their own image. Postcolonial literary theory reads this act of rewriting the canon as a political one that speaks back to power and often advocates for political and cultural independence. Towards the end of the twentieth century and at the beginning of the twenty-first century, Caribbean women writers begin a new wave of rewriting that continues in this tradition, but with certain differences, not least of which is a focused attention to gender and sexuality and to the literary legacies of romance. In the dissertation I consider a number of novels from throughout the region that rewrite the romance, including Jean Rhys's Wide Sargasso Sea (1966), Maryse Condé's La migration des coeurs (1995), Mayra Santos-Febres's Nuestra señora de la noche (2006), and Dionne Brand's In Another Place, Not Here (1996). Romance, perhaps more than any other literary form, exerts an allegorical force that exceeds the story of individual characters. The symbolic weight of romance imagines the possibilities of a social order--a social order dependent on the sexual behavior of its citizens. By rewriting the romance, Caribbean women reconsider the sexual politics that have linked women with metaphorical constructions of the nation while at the same time detailing the extent to which transnational forces, including colonization, impact the representation of love and desire in literary texts. Although ultimately these novels refuse the generic requirements of the traditional resolution for romance (the so-called happy ending), they nonetheless gesture towards a reordering of community and a revised notion of kinship that recognizes the weight of both gendered and sexual identities in the Caribbean. / Committee in charge: Karen McPherson, Chairperson, Romance Languages; David Vazquez, Member, English; Tania Triana, Member, Romance Languages; Judith Raiskin, Outside Member, Womens and Gender Studies

The United States Military is currently organized along the lines of regional combatant commands (COCOMs). Each COCOM is responsible for all U.S. military activity in their designated area of responsibility (AOR). They also deal with diplomatic issues of a wide variety with the countries within their respective AORs. Among these COCOMs, Southern Command (SOUTHCOM), whose AOR encompasses all of Central and South America (less Mexico) and the Caribbean, is one of the smallest in terms of size and budget, but has the longest history of activity among the COCOMs as it is the successor to the first joint command, the United States Caribbean Defense Command (CDC 1941-1947). Existing from 1941 to 1947, the CDC was tasked with protecting the Panama Canal, the Canal Zone, and all its access points as well as defending the region from Axis aggression and setting up a series of U.S. bases throughout the Caribbean from which to project U.S. military power after World War II. Throughout its short history, however, the CDC was plagued with the same types of resource scarcity that its successor commands would later experience. Early successes, as well as the progress of the war saw to it that the original mission of the Command was quickly rendered moot. Ironically, it was partially the success of the U.S. war effort that kept the CDC from ever reaching its full potential. Nevertheless, the CDC evolved into something different than had originally been envisioned. In the end, it became the model that other COCOMs would follow after November 1947 when the system of regional combatant commands was formally established. Although some research has been conducted into the history of these commands, this dissertation is the first academic attempt to chronicle the history of the United States Caribbean Defense Command. Research into this topic involved combing through the Archives of the United States Southern Command in its offices in Miami, Florida (SOUTHCOM Archives), as well as the CDC archives in Record Group 548 in the U.S. National Archives II in Suitland, Maryland. Secondary sources as well as references regarding treaties and international agreements were also consulted as necessary.
