1. Chen, Meilian. Characterization,Sources,and Transformations of Dissolved Organic Matter (DOM) in the Florida Coastal Everglades (FCE).

Degree: Chemistry, 2011, Florida International University

Dissolved organic matter (DOM) is one of the largest carbon reservoirs on this planet and is present in aquatic environments as a highly complex mixture of organic compounds. The Florida coastal Everglades (FCE) is one of the largest wetlands in the world. DOM in this system is an important biogeochemical component as most of the nitrogen (N) and phosphorous (P) are in organic forms. Achieving a better understanding of DOM dynamics in large coastal wetlands is critical, and a particularly important issue in the context of Everglades restoration. In this work, the environmental dynamics of surface water DOM on spatial and temporal scales was investigated. In addition, photo- and bio-reactivity of this DOM was determined, surface-to-groundwater exchange of DOM was investigated, and the size distribution of freshwater DOM in Everglades was assessed. The data show that DOM dynamics in this ecosystem are controlled by both hydrological and ecological drivers and are clearly different on spatial scales and variable seasonally. The DOM reactivity data, modeled with a multi-pool first order degradation kinetics model, found that fluorescent DOM in FCE is generally photo-reactive and bio-refractory. Yet the sequential degradation proved a “priming effect” of sunlight on the bacterial uptake and reworking of this subtropical wetland DOM. Interestingly, specific PARAFAC components were found to have different photo- and bio-degradation rates, suggesting a highly heterogeneous nature of fluorophores associated with the DOM. Surface-to-groundwater exchange of DOM was observed in different regions of the system, and compositional differences were associated with source and photo-reactivity. Lastly, the high degree of heterogeneity of DOM associated fluorophores suggested based on the degradation studies was confirmed through the EEM-PARAFAC analysis of DOM along a molecular size continuum, suggesting that the fluorescence characteristics of DOM are highly controlled by different size fractions and as such can exhibit significant differences in reactivity.

2. Koskina, Aikaterini. Η έννοια της «τελετουργικής μεταμόρφωσης» στο έργο του Λουκά Σαμαρά.

Degree: 2006, National and Kapodistrian University of Athens; Εθνικό και Καποδιστριακό Πανεπιστήμιο Αθηνών (ΕΚΠΑ)

Lucas Samaras is one of the most important artists of the New York scene and at the same time one of the most important Greek-born international artists. His oeuvre has been the object of many studies by art historians and critics, which go beyond art criticism to adopt sociological, semantic and psychoanalytical approaches. The aim of the present doctoral thesis is to study the oeuvre of Samaras from a historical and biographical perspective which centers on the concept and the practice of transformation. Specifically, the aim is to demonstrate that “ritualistic transformation” emerges as the ideological, conceptual, spiritual and methodological trait that runs through the artist’s long and morphologically varied work and unifies it: from the constructions and actions of the 1960s to the stories and the photographic portraits of the 1970s and 1980s and from his 1960s films to his recent digital photo-collages and videos. Samaras perceives and ‘manages’ the creative act as a transformative and reformative force which is associated with the sacred and the sublime. The artist molds not only the materials of his art but also everyday objects from urban life and himself into autonomous works of art; his individual and consistent behavior makes him the protagonist in a Teatro Mundi which brings together the real, the imaginary and his deeper existential world. Through that prism, the artist adopts a stance of strict social isolation which combines with a ritualistic artistic production to turn him into a mystic. This is one parameter which had not been examined thoroughly in previous studies of the work of Samaras. The method selected to support this view approaches the subject in two distinct but complementary ways. The first part of the study [chapters 1-3] uses strictly historical criteria in an attempt at a systematic study and presentation of the art of Samaras [method of work, materials and techniques, impact and perception] in conjunction with the concurrent events in American art, while examining also the influences from the environment in New York and his references to Greece. The reader is thus able to go deeper into the art of Samaras and decode his richly symbolic oeuvre. The second part of the study [chapters 4-6] examines the concept of “ritualistic transformation” as a key to the overall study and analysis of the art of Samaras. Based on religious references, this study demonstrates the ‘holy relationship’ that Samaras develops with (a) his body, (b) his personal space, (c) his myths, and (d) his memories. Thus it transpires that the transformative/reformative character of Samaras’s creations is ‘defined’ by the concept of transformation. We feel that this parameter is essential to a comprehensive, holistic approach to his art.
