Η εργασία αυτή στηρίζεται στα αποτελέσματα των μικροπαλαιοντολογικών αναλύσεων που πραγματοποιήθηκαν σε βενθονικά τρηματοφόρα σε δείγματα ιζήματος. Τα ιζήματα προέρχονται από πυρήνα που συλλέχθηκε από το Ανατολικό Κρητικό πέλαγος. Στα βάθη ιζήματος που επικεντρώνονται τα δείγματα έχουν παρατηρηθεί αλλαγές τόσο στην γεωχημεία των ιζημάτων, όσο και στο ποσοστό οργανικού άνθρακα. Σε αντίστοιχα βάθη στο Δυτικό Κρητικό πέλαγος είχε εντοπιστεί ο σαπροπηλός S2(Geraga et.al 2005). Ο S2 δεν εντοπίζεται συχνά στα ιζήματα των πυρήνων γι’ αυτό αναφέρεται και ως “σαπροπηλός φάντασμα”(ghost sapropel). Σκοπός της εργασίας είναι ο εντοπισμός και η εξέλιξη των παλαιοωκεανογραφιών συνθηκών που επικρατούσαν στον πυθμένα της περιοχής μελέτης για το χρονικό διάστημα μελέτης. / -

This study examines the role of place and ritual performance in the construction of subjectivities and social memories in relation to the 1890s Ghost Dance, a North American pan-Indian ritually-centered social movement that began in western Nevada and spread from the West Coast through the Great Plains during the last decade of the nineteenth century. This dissertation also explores efforts to alternatively preserve, promote, and eradicate practices representing two inherently contradictory spatial regimes, or ways of living as Beings-in-the-World. Such an analysis is done through the study of ritual and social responses to the spatial disruptions and collective identity ruptures evinced by Westward expansionism on the native peoples of the Great Basin and Colorado Plateau called the Numa. This research is designed to advance knowledge of Ghost Dance ceremonial sites and ritual praxis in the Great Basin and Colorado Plateau. This is done through the isolation of physiographic characteristics, performance characteristics, and cultural inscription practices contributing to the selection, valuation, and use of particular ritual settings for Ghost Dance performances. I hypothesized that three types of sites, World Balancing Places, Regional Balancing Sites, and Local Balancing Sites, or Regions of Refuge, were used for ceremonialism associated with the Ghost Dance among Numic people. Type I sites are ceremonial sites that were used consistently before the arrival of Euroamericans and continued to be used during the late nineteenth century for the performance of the Ghost Dances. Both World and Local Balancing Places are Type 1 Sites. Type II sites are defined as places that were selected as ceremonial sites after encroachment activities made the performance characteristics of Type I Sites nonviable. The social unit of the present analysis is the Great Basin and Colorado Plateau. The current methodological framework has been formulated with the intent of producing a holistic treatment of Numic ritual landscapes as evidenced in Ghost Dance ceremonial sites. To this end, I have adopted an intersubjective and iterative approach that utilizes performance and narrative studies, behavioral archaeology, cultural landscape studies, and phenomenology. This research aims to contribute to the theory and methodology underscoring National Historic Preservation efforts.

This essay sets out to illustrate the evolution of horror in ghost stories through a literary analysis of M.R. James’s “The Mezzotint” (1904) and Susan Hill’s The Man in the Picture (2007). It is shown that despite many similarities, The Man in the Picture is a more frightening story than “The Mezzotint” mainly because of five major differences in the narrator, the haunted picture, the build-up of suspense, the relationship between the ghost and its victims, and the resolution of the mystery. Many critics have dealt with the ghost story genre before but no one seems to have analysed James’s and Hill’s stories in the way that is presented in this essay. In addition to the analysis, the essay also includes a pedagogical chapter, showing how a ghost-story project in upper-secondary school can improve the students’ language, their knowledge of literature and their critical thinking.

Following contemporary readings/writings of the ghosts of Hamlet’s father, in particular those of Derrida, Borges, and Joyce, this study intends to further elucidate the affiliation between scholar, spectre, and archive. This work demonstrates how Hamlet both conforms to a scholarly process of archivization and a silencing of the ghost, and simultaneously renders a slipping away of the spectre at its precise point of capture, engendering the infinite archive that is “irreducible by explanation” (Derrida, 1998, p. 87) and never closed. It is this opening and pulling apart, this expansion at the point of its closure, that allows the ghosts of Shakespeare and his Hamlet to enter into the texts of Borges, Joyce, and Derrida.

This essay is a literary analysis of two ghost stories, Elizabeth Gaskell’s “The Old Nurse’s Story” (1852) and Susan Hill’s The Man in the Picture (2007). The main focus of the essay is the theme of revenge, which is explored on the basis of similarities and differences in the mentioned ghost stories. It is shown that, in spite of many similarities, The Man in the Picture is a more developed and less conventional ghost story than “The Old Nurse’s Story”. This development is seen in the setting, the narrators and the structure of the story, all of which contain more layers in Susan Hill’s story. The essay also includes a didactic chapter which shows how a teacher can use the two ghost stories in the classroom to teach students in upper secondary school about literary analysis and the Gothic genre.

This study explores the morphology and electrical behavior of breeding weakly electric fish. Wave-type electric fish communicate by means of a continuous oscillatory electric signal produced by an electric organ. The electric organ discharges at frequencies which are sexually dimorphic in many species of electric fish. This dimorphism is thought to be attributed to female mate choice, although to date, there is no evidence for mate choice or intrasexual competition to have driven the evolution of this signaling dimorphism in wave-type electric fish. Here, I have tracked changes in body shape and electric organ discharge (EOD) frequency of A. leptorhynchus throughout a breeding conditioning period. I find that only females alter the shape of their bodies, presumably to account for increasing egg mass, during the breeding conditioning period. Throughout this period, both females and males do not alter their EOD frequencies significantly. Gravid females were used in an unforced preference test, where they were presented with two live, male A. leptorhynchus. Female preference was indicated by a passage of the female into one of the two male compartments. I find that females show a preference for higher EOD frequency males, while no preference is shown for longer, heavier or larger-amplitude males. Further investigations are needed to dissociate the role of EOD frequency from potentially correlated male traits, such as rate and type of modulations of EOD frequency. The finding of this study that female A. leptorhynchus prefer males of higher EOD frequency establishes wave-type weakly electric fish as a promising model system for the study of the evolution and the sensory mechanisms of female choice.
