The University of the West Indies (UWI), established in the British colony of Jamaica in 1948, was mandated to serve the “brightest and the best” of the British colonies. Unfortunately, the austerity of Jamaica's economy has not helped to augment an “open door” access to higher education, and UWI is often criticized for not implementing policies to sustain the democratization of higher education; it is accused of functioning as an elitist institution. ^ The purpose of this qualitative study was to determine whether UWI functions democratically as an institution to influence the equity of higher education in Jamaica. A review of the literature reveals many interpretations of the democratization of higher education. Three of Spaulding and Kargodorian's four criteria were utilized to analyze this research. They were (1) equality of access to higher education, (2) equality of participation within the institution of higher education, and (3) equality of educational results. Multiple sources of written data augmented by interviews in Jamaica and Miami were utilized. ^ The analysis revealed that UWI functions in a collaborative relationship with Jamaica's Centralized Educational System as well as with the country's political, economic, and social realms to impact the democratization of higher education. Documentation suggests that, although strong traditional influences continue to exist, UWI has deviated from its original mandate and instead, flexible admittance policies and diversification of expanded programs have contributed to greater accessibility. ^ Despite UWI's reports of improvements which have contributed to more access, UNESCO and some interviewees have not been impressed. A World Bank report on enrollment ratio at the university level in English speaking Caribbean countries reflects less than one percent of the age cohort. The Jamaicans interviewed, especially those from the lower class, felt that their democratic right to receive higher education was not met. UNESCO regards UWI's efforts as just putting a “dent” in the problem. ^ Recommendations include continuing efforts towards developing curricula more relevant to the Jamaican society, increasing distance education in order to ease UWI's load, expanding financial partnerships with private sectors, and extending research in collaboration with large local and foreign private companies. ^

A multipurpose open architecture motion control system was developed with three platforms for control and monitoring. The Visual Basic user interface communicated with the operator and gave instructions to the electronic components. The first platform had a BASIC Stamp based controller and three stepping motors. The second platform had a controller, amplifiers and two DC servomotors. The third platform had a DSP module. In this study, each platform was used on machine tools either to move the table or to evaluate the incoming signal. The study indicated that by using advanced microcontrollers, which use high-level languages, motor controllers, DSPs (Digital Signal Processor) and microcomputers, the motion control of different systems could be realized in a short time. Although, the proposed systems had some limitations, their jobs were performed effectively. ^

Since the 1985 return to democracy, Brazilian politicians have resorted to vote-pooling arrangements to elect representatives. A puzzle thus presents itself: What drives parties to join these electoral cartels? The dissertation unraveled the incentives party elites have to participate in coalitions under a presidencialist system of government. I also investigated the effect of electoral coalitions on congressional representation. I applied a model of binary outcomes and relied on standard deviations to assess the ideological homogeneity/heterogeneity of electoral coalitions. I also calculated the Index of Disproportionality to measure the gaps between the proportion of votes and seats received by all parties in Brazil with and without electoral coalitions. Finally, I assessed the effects of the electoral formula on proportionality. An unexpected exogenous factor resulted crucial in explaining proportional electoral coalition building: The district's majoritarian election for governor. In each district, political actors often synchronize coalition partners to maximize winning results while minimizing electoral efforts.

The economic development of any region involves some consequences to the environment. The choice of a socially optimal development plan must consider a measure of the strategy's environmental impact. This dissertation tackles this problem by examining environmental impacts of new production activities. The study uses the experience of the Carajás region in the north of Brazil. This region, which prior to the 1960's was an isolated outpost of the Amazon area, was integrated to the rest of the country with a non-sophisticated but strategic road system and eventually became the second largest iron ore mining area in the world. Finally, in the 1980's, the area was linked, by way of a railroad, to the nearest seaport along the Atlantic Ocean. The consequence of such changes was a burst of economic growth along the railroad Corridor and neighboring areas. In this work, a Social Accounting Matrix (SAM) is used to construct a 2-region (Corridor and surrounding area), fixed price, Computable General Equilibrium (CGE) Model to examine the relationship between production and pollution by measuring the different pollution effects of alternative growth strategies. SAMs are a very useful tool to examine the environmental impacts of development by linking production activities to measurable indices of natural resource degradation. The simulation results suggest that the strategies leading to faster economic growth in the short run are also those that lead to faster rates of environmental degradation. The simulations also show that the strategies that leads to faster rates of short run growth do so at the price of a rate of environmental depletion that is unsustainable from a long run perspective. These results, therefore, support the concern expressed by environmental economists and policy makers regarding the possible trade-offs between economic growth and environmental preservation. This stresses the need for a careful analysis of the environmental impacts of alternative growth strategies. ^
