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

Trinidad and Tobago is one of 15 small developing states that comprise the regional integration grouping known as the Caribbean Community. Several agencies were recently created outside of the government using a strategy known as agencification to support the implementation of public policy in the Republic of Trinidad and Tobago. However, there is little available information explaining the rationale for the choice of the strategy, no evidence-based scholarly evaluation found on the effectiveness of these types of agencies, and therefore limited information on whether this strategy results in effective public policy. The purpose of this case study was to gain an in-depth understanding of these semi-autonomous agencies in the implementation of public policy in Trinidad and Tobago as part of the Caribbean Community. The central research question sought to explore the successes, failures, and experiences with executive agencies created through agencification. Principal-agent theory provided the theoretical framework for this qualitative case study. Using a purposive sampling strategy, data were acquired through interviews with 10 individuals representing public servants, agency officials, and academics and a review of public documents. The data were inductively coded and then organized across themes. The findings indicated that while the agencification strategy is being utilized with varying levels of success, several barriers and constraints hamper successful policy implementation. Positive social change implications of this study include direct recommendations for greater autonomy for the directorate of all agencies in the Republic of Trinidad and Tobago. These recommendations would serve to facilitate the implementation of the policies that they were created to support.
