Caribbean nations lie within a zone of distinct seismic hazard. While ground motion in the region has been analyzed, the potential for liquefaction has not been evaluated in most cases. In order to evaluate liquefaction, data describing soil composition, surficial geology, and seismic hazard analyses were collected and applied. This allowed for expansion of previously localized liquefaction analysis to be expanded to the extents of two island nations in the Caribbean. This thesis utilizes the Youd and Perkins (1978) qualitative liquefaction susceptibility and Holzer et al. (2011) liquefaction probability methodologies to evaluate the possibility of liquefaction in Trinidad and Jamaica during major seismic events. Maps were developed using geographic information system (GIS) data to compare susceptibility and hazard across the islands at varying levels of magnitude. In this way, the distribution of liquefiable deposits is displayed in a manner that can be used quickly and easily to motivate further study of susceptible regions and mitigation activities to reduce the risk posed by liquefaction in the countries.

The present study employs the frameworks of postcolonial literary theory, sociolinguistics, and the social psychology of language use to compare the nature, function, and meaning of English in the delineation of cultural and social identities in anglophone Zimbabwean and Trinbagonian literatures. The construction of cultural and social identities in these literatures inheres in how certain Zimbabwean and Trinbagonian novelists use various linguistic devices to contextualize the English language in their respective cultures, and how they employ the English language to articulate and reinforce colonial, counter-colonial, and other heteroglossic social discourses arising from conflicts of race, class, and gender in the Zimbabwean and Trinbagonian contexts. Chapter One outlines the nature of the research and sets up the terms and categories that will feature prominently in the analysis. Chapter Two examines the place of English in the socio-economic and cultural history of Zimbabwe and of Trinidad and Tobago, and offers a description of the indigenous or other national languages which play prominent roles in the linguistic configuration of the two nations. The chapter also critically reviews the attitudes of some prominent post-colonial writers, particularly from the African and Caribbean regions, to the use of English as a medium of artistic creativity. Chapter Three engages with narrative idiom and characters' idioms and comments as they relate to (a)the nativization of English in selected Zimbabwean novels and the use of English and other indigenous languages for articulating social norms and certain situational imperatives, and (b) the power and politics of English as an instrument for domination, manipulation, oppression, the construction of elitist identity, the reproduction of unequal power relations, and of resistance to such social injustice. Chapter Four addresses issues discussed in Chapter Three, but with reference to the Trinbagonian literary context. Chapter Five, the conclusion, synthesizes the arguments by pointing out the sociolinguistic similarities and differences between Zimbabwean and Trinbagonian Literatures analyzed in the study. Furthermore, the concluding chapter not only indicates the values of an interdisciplinary project such as this one for both linguistics and literary studies, but it also delineates certain research options for the future. The dissertation generally concludes that the construction of Zimbabwean and Trinbagonian identities in and through language can be read as a mode of resistance to the homogenizing, assimilative practices of colonialism and neo-colonialism. Thus, the detailed documentation provided in this study of the range of linguistic and socio-cultural differences between Zimbabwean and Trinbagonian literatures on the one hand, and other works of English (especially the acrolectal varieties) on the other, establishes that while there is no single, stable Zimbabwean or Trinbagonian identity that is constituted in the language of literary texts to set up in contrast to an imperial British or American one, the fact of differences is indisputable.

Slope-channels act as conduits that transport sediments from the shelf staging area to the basin floor. The Pliocene-Pleistocene section of the Columbus Basin in the deep-water slope offshore eastern Trinidad provides an opportunity to study slope-channel morphology and evolution, as well as any association between deep-water deposits, palaeo-seafloor bathymetry, shelf sediment feeder mechanism and changes in sediment supply types and volumes. Approximately 3250 km2 of 3D seismic data allow imaging and interpretation of channels within an interval between two regional surfaces termed P30 and P40. Observations of seismic cross-sections and stratal slices reveal a number of features including channels, mud diapirs, mass transport deposits (MTDs), and faulted anticlinal ridges. Channels appear leveed and unleveed, and alternate with MTDs in a cyclic vertical succession. Nineteen channels were mapped and divided into two groups based on their degree of levee development and stratigraphic position relative to MTDs. Group 1 channels, positioned below MTDs near the base of the interval, are shallowly incised, and show limited levee development. Group 2 channels, situated above MTDs, are relatively deeply incised, and have comparatively larger, well-developed levees throughout their lengths. Morphometric data from these channel groups reveal significant variability in channel width, channel depth, meander belt width, and sinuosity downslope. This variability is associated with influences of temporally equivalent local features and regional sea-floor slope changes. Increased slope gradient causes a marked increase in sinuosity. Diapirs and anticlinal ridges confine channel paths, divert their flow, and cause post-depositional deformation of both levees and channels. Levee height decreases downslope while levee width shows considerable asymmetry, which is related to occurrences of mud diapirism and MTDs. Irregularities on the upper surface of MTDs create accommodation space that confines turbidity flows, enabling ponding of sediments and volumetrically large levee construction. This accounts for dispersion of turbidity flows below the MTD which creates a series of small channels spread over a wide area, and comparatively fewer, confined channels above the MTDs with large levees. / text

This dissertation examines the production of culture among Indo-Caribbean communities in New York City and Trinidad. It seeks to understand how cultural producers use performance as a way to mediate their experiences of racialization in local, national, and transnational spheres. Based on a multisited ethnographic study, I analyze the Indo-Caribbean diaspora as a result of nineteenth and twentieth century indentured labor migration and as a focus of post-1965 transnational migration. To do so, I introduce the idea of "transnational performances," which I employ to examine how expressions of Indo-Caribbean identity are performed in Trinidad and New York City as a way of mediating global processes. Specifically, this dissertation begins with a geographic and historical overview of Indo-Caribbean transnational populations, then provides an ethnographic study of contemporary Hindu religious festivals in Trinidad, an Islamic festival held in both New York City and Trinidad, Indo-Caribbean media in New York, and a cultural and arts center in New York. In all these sites Indo-Caribbean cultural producers engage the politics of public representation of Indo-Caribbean identity. I argue that while Indo-Caribbean religious, festival, media, and cultural producers engage with diasporic formations of identity and develop diasporic narratives that address Indian origins, they simultaneously develop new, creative, and flexible Indo- Caribbean transnational performances in the public sphere often coproducing their identities in relation to other diasporic communities. Concerns about authenticity exist alongside the desire to create new cultural practices that employ hybridity as a strategy to assert belonging. These transnational performances are spaces from which Indo-Caribbean communities develop a public voice that responds to perceived exclusions and erasures. The geographies of belonging that are central in the transnational performances of Indo-Caribbean cultural producers suggest that we must attend to the cultural practices developed within and across boundaries while taking a historical perspective on global processes that are reconfigured in the contemporary period. / text

The study area is situated along the obliquely converging boundary of the Caribbean and South American plates offshore eastern offshore Trinidad. Major structural elements in the shelf break and deep-water slope regions include normal and counter-normal faults to the south and large transpressional fault zones to the north. Well logs and biostratigraphic information were analyzed for twenty-four wells in the study area to refine previous depositional environment interpretations. For purposes of this net sand distribution analysis it was decided to consider the deltaic portion of the shelf transit cycle, against the marine portion of the shelf transit cycle and were named T and R cycles, respectively. T and R cycles were interpreted based on well log patterns and depositional facies shifts. Six T/R cycles were interpreted within the Pliocene to recent stratigraphic succession and shelf edge trajectories were also mapped for each of these cycles based on earlier stratigraphic correlations. Net-to-gross (NTG) ratios were calculated for each component of the T/R cycles and plotted against total thicknesses and net sand values. In addition, NTG trends were mapped for each interval and analyzed based on their proximity to the corresponding shelf edge. Mapping of the shelf edge trajectories (SET) revealed that (1) SET migrate northeasterly across the Columbus Basin through time and (2) shelf edge orientations are parallel to the strike of growth faults in the south but deflect to the northeast near the Darien Ridge indicating a strong underlying structural control. The NTG plots and maps also revealed that (1) For T cycles, NTG values never exceed 60% and are inversely proportional to total thickness, (2) For R cycles, NTG values are highly variably ranging from 35% to 90%, (3) NTG values increase as the shelf break is approached and (4) The distribution of NTG ratios is also controlled by accommodation space created by local structures. The Guiana current is believed to play an important role in the redistribution and reworking of sand in the Columbus Basin. Aggradation and progradation distances were computed for each interval and the results suggest that the younger Sequences C2 (T-R cycle E) and C3 (T-R cycle F) show a stronger progradational trend than the older C4, C5 and C6. This strong progradational trend might indicate delivery of sand basinwards, while for the older intervals; the aggradational trend suggests an increase in sediment storage. In long-term scale (1-2 m.y.) the Orinoco Delta seems to behave as an aggradational delta that increases sediment storage due to growth fault and high subsidence rates. However, in the short-term scale, the Orinoco delta seems to behave as a rapid progradational delta, for the younger sequences C2 and C3, where sediment bypass is more likely to occur; and as a rapid aggradational (slow prograding) margin for the older intervals C4, C5 and C6. / text

This report chronicles a conflict over a Canadian-owned silver and gold mine in San José del Progreso, Oaxaca, as told by the author’s first-hand experience, eyewitness interviews, and research. Beginning with the Mexican Federal Government’s concession of ejidal land for use by the mining company, without the consent or consultation of the surrounding population, elaboration of the Trinidad mine in San José del Progreso has resulted in division in the community and intense activism, sometimes resulting in violent conflict. / text

Agricultural producers and consumers are experiencing a communication disconnect as the population shifts from rural to urban societies. It is critical to assess producer and consumer perspectives to create a functional agricultural environment. The purpose of this study was to describe the consumer market and the farming industry environments in Trinidad and Tobago through consumers’ perceptions of their produce, a comparison of student and consumer perceptions of their produce, and agricultural professionals’ perceptions of the industry environment. Quantitative and qualitative research methods were used to complete this study. The study of consumers’ perceptions of their produce provided a quantitative description of attitudes held about produce origin and growing methods and their effect on pricing. An instrument was developed to measure the three constructs. Data were collected in farmers markets. Descriptive statistics were used for reporting consumer perceptions and demographics. The results of this study suggest that consumers are supportive of local, organically grown produce for their health and environmental benefits. A second study described students’ perceptions of their produce in comparison with consumers’ perceptions. The Culture and Consumer Behavior Interaction Model of Luna and Gupta provided the framework to explore the effects of cultural values and market communications on consumer behavior. Data were collected from university students using a questionnaire. Descriptive statistics were used for reporting student perceptions and demographics; the data were compared with the consumer data from the first study. The results of this study suggest students and consumers have different cultural values and access to marketing communication and, therefore, behave differently when purchasing produce. The third study was a qualitative case study exploring agricultural industry professionals’ perceptions of the industry environment. Rogers’ theory of diffusion provided the framework to explore information access for producers in Trinidad and Tobago. Data were collected through interviews. Crop production methods, sources of information, and perceived needs to improve the industry emerged as themes. The results suggest the need for a standardized definition of organic growing methods, a centralized location of information and training materials, governmental support and public recognition of agriculture efforts, and career potential for youth interested in the farming industry.

xi, 249 p. : ill. (some col.) / Globalization has inaugurated many rapid changes in local communities throughout the world. The globalization of media, both electronic and print, has introduced new pressures for local communities to confront while also opening up new imaginative possibilities. As many observers have noted, transnational media transform local public cultures, or shared imaginative spaces, but never in predictable, totally hegemonic ways. This dissertation focuses on the efforts of a small Hindu community called the Hindu Prachar Kendra located in Trinidad, West Indies, as they develop critical strategies that help their children read, negotiate, and in some cases contribute to local and global public cultures. I argue that though many Hindu parents and teachers of the Kendra share anxieties about the effects of local and global popular cultures on their children, they also use many features, ideas, and texts emerging from imaginative media in creative ways. Furthermore, their concerns about media shape their interpretation and instruction of Hindu practice. / Committee in charge: Philip Scher, Chair; Lynn Stephen, Member; Lamia Karim, Member; Deborah Green, Outside Member
