The ethical paradigm of Jose Marti's writings beyond Modernity

This dissertation explores the nature of Jose Marti's ethical ideas in relation to the rise of late Nineteenth Century Modernity and in tandem with the deconstruction and subversion of the principal constituencies of colonial and aesthetic discourses. Marti proposes a new paradigm that question the insatiable pursuit of novelty, the hostility towards tradition, the historical perspectivism and a critical stance with regard to social aesthetic Modernity. He also questions the cult of reason, the linear historicism, and the teleological progress framed in philosophical utilitarian pragmatism of bourgeois Modernity. His radical criticism of the structures and institutions of the hegemonic power of the modern state override the ontological and epistemological foundations of Modernity. Marti's deconstruction of the fundamental discourses of euro-centristic Occidental culture leads him, through his ethical writings, to an arqueology of Native American civilizations, thus reinserting, within the false premises of European universalism, his counter-discourse of tradition and the voice of the Other.

Formal verification and testing of software architectural models

Ensuring the correctness of software has been the major motivation in software research, constituting a Grand Challenge. Due to its impact in the final implementation, one critical aspect of software is its architectural design. By guaranteeing a correct architectural design, major and costly flaws can be caught early on in the development cycle. Software architecture design has received a lot of attention in the past years, with several methods, techniques and tools developed. However, there is still more to be done, such as providing adequate formal analysis of software architectures. On these regards, a framework to ensure system dependability from design to implementation has been developed at FIU (Florida International University). This framework is based on SAM (Software Architecture Model), an ADL (Architecture Description Language), that allows hierarchical compositions of components and connectors, defines an architectural modeling language for the behavior of components and connectors, and provides a specification language for the behavioral properties. The behavioral model of a SAM model is expressed in the form of Petri nets and the properties in first order linear temporal logic.^ This dissertation presents a formal verification and testing approach to guarantee the correctness of Software Architectures. The Software Architectures studied are expressed in SAM. For the formal verification approach, the technique applied was model checking and the model checker of choice was Spin. As part of the approach, a SAM model is formally translated to a model in the input language of Spin and verified for its correctness with respect to temporal properties. In terms of testing, a testing approach for SAM architectures was defined which includes the evaluation of test cases based on Petri net testing theory to be used in the testing process at the design level. Additionally, the information at the design level is used to derive test cases for the implementation level. Finally, a modeling and analysis tool (SAM tool) was implemented to help support the design and analysis of SAM models. The results show the applicability of the approach to testing and verification of SAM models with the aid of the SAM tool.^

Experiential hospitality environments: The roles of the interior architectural features in affording meanings of place

People’s authentic sense of place is being overshadowed by less authentic experiences referred to as placelessness. Consequently, a demand for experiential interior environments has surfaced. Experiential environmental and place attachment theories suggested that the relationships between self, others, and the environment are what encourage users in creating meaningful authentic experiences. This qualitative study explored the roles of the experiential interior architectural features in affording users of hospitality environments higher-level needs, such as meanings of place. For the case study, ten participants stayed at a hotel for two nights. Participants were given a guided list of ten facets of an experience, which was insidiously structured by both experiential environmental and place attachment theories. The participants used photographs to document each of the facets on the guided list. The photos were then used during the photo elicitation interviews, which evoked additional qualitative information. Participants identified specific interior architectural features and described them using the themes associated to place attachment theories. The findings revealed that the interior architectural features might enrich the meanings a person associates with a given place. Possibly affording users higher-level needs. As a result, if an experiential interior environment allows users to foster relationships between self, others, and the physical environment, they may experience more authentic experiences and give more meanings to a place.

Effects of architectural features of air-permeable roof cladding materials on wind-induced uplift loading

Widespread damage to roofing materials (such as tiles and shingles) for low-rise buildings, even for weaker hurricanes, has raised concerns regarding design load provisions and construction practices. Currently the building codes used for designing low-rise building roofs are mainly based on testing results from building models which generally do not simulate the architectural features of roofing materials that may significantly influence the wind-induced pressures. Full-scale experimentation was conducted under high winds to investigate the effects of architectural details of high profile roof tiles and asphalt shingles on net pressures that are often responsible for damage to these roofing materials. Effects on the vulnerability of roofing materials were also studied. Different roof models with bare, tiled, and shingled roof decks were tested. Pressures acting on both top and bottom surfaces of the roofing materials were measured to understand their effects on the net uplift loading. The area-averaged peak pressure coefficients obtained from bare, tiled, and shingled roof decks were compared. In addition, a set of wind tunnel tests on a tiled roof deck model were conducted to verify the effects of tiles' cavity internal pressure. Both the full-scale and the wind tunnel test results showed that underside pressure of a roof tile could either aggravate or alleviate wind uplift on the tile based on its orientation on the roof with respect to the wind angle of attack. For shingles, the underside pressure could aggravate wind uplift if the shingle is located near the center of the roof deck. Bare deck modeling to estimate design wind uplift on shingled decks may be acceptable for most locations but not for field locations; it could underestimate the uplift on shingles by 30-60%. In addition, some initial quantification of the effects of roofing materials on wind uplift was performed by studying the wind uplift load ratio for tiled versus bare deck and shingled versus bare deck. Vulnerability curves, with and without considering the effects of tiles' cavity internal pressure, showed significant differences. Aerodynamic load provisions for low-rise buildings' roofs and their vulnerability can thus be more accurately evaluated by considering the effects of the roofing materials.

Sustaining culture through architecture : how can local, vernacular architectural principles be adapted to contemporary design in a village in Guyana

This thesis explores how architecture can adapt local vernacular design principles to contemporary building design in a rural setting. Vernacular buildings in Guyana present a unique and coherent set of design principles developed in response to climatic and cultural conditions. The concept of “habitus” proposed by philosopher Pierre Bourdieu describing the evolving nature of social culture was used to interpret Guyanese local buildings. These principles were then applied to the design of a Women’s Center in the village of Port Mourant on the east coast of Guyana. The design specifically interpreted the “bottom-house” of local Guyanese architecture, an inherently flexible transitional outdoor space beneath raised buildings. The design of the Women’s Center demonstrates how contemporary architectural design can respond to climatic requirements, local preferences and societal needs to support the local culture.

Tittmann and the 'Tiger Car' : competing conceptions of modernity in Haiti, 1946-50

The purpose of this project was to address the lack of scholarship on mid-twentieth century Haitian history and illustrate its significance. It employs primary and secondary sources in shaping a Gramscian historical narrative. Ideas of "everyday resistance" and internal and external politics are also be of significance to this work. In mid-twentieth century Haiti, the black-nationalist rhetoric of noirisme became the dominant political ideology. Blackness was amorphous and its application to politics was dependent upon class. In proclaiming blackness the average Haitian was attacking the class schism that beleaguered the island. Yet for the elite noirismewas a conduit to modernity and a useful tool for muting the division between rich and poor. With the election of Dumarsais Estimé in 1946, dialogue between the U.S. government, the Haitian elite, and the masses, relative to definitions of modernity played out within the new political reality of noirisme.
