Links across the Gulfstream: The Florida /Bahamas zone, 1780–1900

The links created between Florida and the Bahamas from 1780 to 1900 constituted a major influence in the evolution of a unique society. This dissertation adds to the understanding of this topic by using primary sources and architecture to follow the odyssey of the people who shaped this region. Building on the historiography which examined each area separately, this work focused on the ties forged in the interactions between Florida and the Bahamas. Following the immigrants who shaped Florida and the Bahamas, this work examines cultural holdovers which influenced this region during times of demographic flux. Aesthetic preferences stood out as one way that people maintained connections to their past. The use of architecture as a lens to view this process provides a concrete example of this phenomenon. The societies of Florida and the Bahamas remained intertwined during the late eighteenth and early nineteenth centuries. Forced migrations shaped the trajectory of the evolution of a distinctive culture in these areas bordered by the Gulfstream. This dissertation proves that the links forged between these societies reinforced the patterns which endured throughout the maturation of this area.

La utopía interior: Superación del dualismo en los ensayos de Ernesto Sábato

My research attempts to demonstrate how Sábato’s essays have pursued a progressive path that reflects the evolving process of his vision. In light of his essays, I will delineate the themes of solitude, death, desperation, robotization of man, and finally, hope as the antithesis. In my analysis I examine the model created in Sartre’s Existentialism. I also visit the model followed by Nicholas Berdyaeff, who at least offers the possibility of salvation in a world conceived by and for Nothingness. I investigate how these and other tendencies had an initial influence on the essays studied in my research. I concentrate on those essays whose discourse is conditioned by the philosophical foundations of a being that inquires and discerns, discovers and denounces, and finally struggles with the impossibility of reaching the absolute. This foresight, at times apocalyptic, at times utopian, is already present in Sábato’s early works. In my study I attempt to establish how Sábato, in oscillating between the demonic and the romantic, the infernal and utopian, constructs his vision of the world through the symbiotic intertwining of both the fictional and essayistic genres. I focus on an author compromised by a constant debate with the paradoxes and dichotomies that, according to Sábato himself, define Modernity.

Infants' selective attention to faces and prosody of speech: The roles of intersensory redundancy and exploratory time

One of the overarching questions in the field of infant perceptual and cognitive development concerns how selective attention is organized during early development to facilitate learning. The following study examined how infants' selective attention to properties of social events (i.e., prosody of speech and facial identity) changes in real time as a function of intersensory redundancy (redundant audiovisual, nonredundant unimodal visual) and exploratory time. Intersensory redundancy refers to the spatially coordinated and temporally synchronous occurrence of information across multiple senses. Real time macro- and micro-structural change in infants' scanning patterns of dynamic faces was also examined. ^ According to the Intersensory Redundancy Hypothesis, information presented redundantly and in temporal synchrony across two or more senses recruits infants' selective attention and facilitates perceptual learning of highly salient amodal properties (properties that can be perceived across several sensory modalities such as the prosody of speech) at the expense of less salient modality specific properties. Conversely, information presented to only one sense facilitates infants' learning of modality specific properties (properties that are specific to a particular sensory modality such as facial features) at the expense of amodal properties (Bahrick & Lickliter, 2000, 2002). ^ Infants' selective attention and discrimination of prosody of speech and facial configuration was assessed in a modified visual paired comparison paradigm. In redundant audiovisual stimulation, it was predicted infants would show discrimination of prosody of speech in the early phases of exploration and facial configuration in the later phases of exploration. Conversely, in nonredundant unimodal visual stimulation, it was predicted infants would show discrimination of facial identity in the early phases of exploration and prosody of speech in the later phases of exploration. Results provided support for the first prediction and indicated that following redundant audiovisual exposure, infants showed discrimination of prosody of speech earlier in processing time than discrimination of facial identity. Data from the nonredundant unimodal visual condition provided partial support for the second prediction and indicated that infants showed discrimination of facial identity, but not prosody of speech. The dissertation study contributes to the understanding of the nature of infants' selective attention and processing of social events across exploratory time.^
