SATURN'S INNER SATELLITES: ORBITS, MASSES, AND THE CHAOTIC MOTION OF ATLAS FROM NEW CASSINI IMAGING OBSERVATIONS
No full textInternational audienceWe present numerically derived orbits and mass estimates for the inner Saturnian satellites, Atlas, Prometheus, Pandora, Janus, and Epimetheus from a fit to 2580 new Cassini Imaging Science Subsystem astrometric observations spanning 2004 February to 2013 August. The observations are provided as machine-readable and Virtual Observatory tables. We estimate GM Atlas = (0.384 ± 0.001) × 10 −3 km 3 s −2 , a value 13% smaller than the previously published estimate but with an order of magnitude reduction in the uncertainty. We also find GM Prometheus = (10.677 ± 0.006) × 10 −3 km 3 s −2 , GM Pandora = (9.133 ± 0.009) × 10 −3 km 3 s −2 , GM Janus = (126.51 ± 0.03) × 10 −3 km 3 s −2 , and GM Epimetheus = (35.110 ± 0.009) × 10 −3 km 3 s −2 , consistent with previously published values, but also with significant reductions in uncertainties. We show that Atlas is currently librating in both the 54:53 co-rotation-eccentricity resonance (CER) and the 54:53 inner Lindblad (ILR) resonance with Prometheus, making it the latest example of a coupled CER-ILR system, in common with the Saturnian satellites Anthe, Aegaeon, and Methone, and possibly Neptuneʼs ring arcs. We further demonstrate that Atlasʼs orbit is chaotic, with a Lyapunov time of ∼10 years, and show that its chaotic behavior is a direct consequence of the coupled resonant interaction with Prometheus, rather than being an indirect effect of the known chaotic interaction between Prometheus and Pandora. We provide an updated analysis of the second-order resonant perturbations involving Prometheus, Pandora, and Epimetheus based on the new observations, showing that these resonant arguments are librating only when Epimetheus is the innermost of the co-orbital pair, Janus and Epimetheus. We also find evidence that the known chaotic changes in the orbits of Prometheus and Pandora are not confined to times of apse anti-alignment
The Creatures of Prometheus Ballet (Australian Premiere)
No full textResearch Background:
This research is on Conducting Beethoven’s The Creatures of Prometheus Ballet: An Autoethnographic Study in Performance Practice. The central research question is: what specialised artistic skills and artistic relationships are required to successfully conduct The Creatures of Prometheus ballet? The intention is to build a greater awareness of the role of a ballet conductor, thereby developing a firm grasp on the full capabilities, requirements and duties that a ballet conductor has to perform on a regular basis. These involve collaboration with choreographers, analysis of the score, rehearsing with dancers and the ability to conduct an orchestra. By utilising this ballet as my primary focus, it will help inform what specialised skills were applied and could be used on other ballets.
Research Contribution:
By presenting this Australian Premiere it has contribute to the cultural landscape of works performed by emerging Australian artists, creators and performers. This performance may also go a long way to recognising the significance of Beethoven’s rare ballet and reintroduce this work to the existing canon of ballet repertoire.
Research Significance:
This 220 year-old ballet was premiered in Brisbane, Australia 2021 and witnessed by over 1000 audience members and reviewed by two major arts critics. To date there has been no significant attempt to recreate a stylistically and historically appropriate retelling of the original story since its first premiere in 1801. Finally, using this model of research will highlight challenges and strategies that future ballet conductor’s could employ in their own development for other ballet productions.No Full Tex

Workshops on digital epigraphy and storytelling within the project PROMETHEUS
No full textThe EU co-founded project PROMETHEUS – Promoting Universal Values through Digital Epigraphy and Cultural Heritage is a collaborative initiative involving educational and research institutions aimed at integrating successful digital epigraphy practices with teaching methodologies. The project’s primary goal is to create a thematic digital resources and a storytelling platform that uses narrative elements to contextualize and present the contents of epigraphic monuments, making them more accessible and engaging for a broader, non-expert audience. The aim is to foster appreciation for the historical and cultural narratives preserved within these epigraphic monuments and the universal values they address

Prometheus Through the Ages
No full textThis dissertation explores the role and significance of the ancient Greek myth of Prometheus in Western philosophy from Antiquity to today. Paying particular attention to its moral and existential meanings, an analysis of this in-depth investigation produces an overview of the exceptional array of the myth’s functions and themes. It demonstrates that the most significant functions of the Prometheus myth are its social, epistemic, ontological and moral functions and that the myth’s most significant themes are fire, rebellion, creation, human nature and ambiguity. The dissertation argues that this analysis brings to light meaningful information on two sides of a reference to the Prometheus myth: it reveals the nature, functions, themes and connotations of the myth, while information about these functions and themes provides access to fundamental meanings, moral statements and ontological concepts of the studied author. Based on its findings this work claims that, as in history, first, the Prometheus myth will still be meaningful in philosophy today; and second, that the analysis of the myth’s functions and themes will provide access to essential ideas underlying contemporary references to the myth. To prove the validity of these claims this thesis examines the contemporary debate on ‘human enhancement’. Advocates as well as opponents of enhancement make use of the Prometheus myth in order to support their arguments. Employing the acquired knowledge about the myth’s functions and themes, the dissertation analyses the references encountered. The results of this analysis confirm that the Prometheus myth still has a significant role in a contemporary philosophical context. They improve our understanding of the philosophical argument, ontological framework and ethics of the debate’s participants; and thus demonstrate that the information about the Prometheus myth acquired in this thesis is a useful means to reveal fundamental ideas and conceptualisations underlying contemporary (and possibly future) references to the myth.School of Humanities and Social Sciences, University of Exete

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics

Placing Prometheus
No full text‘A poet’s work is to name the unnameable, to point out frauds, to take sides; start arguments, shape the world and stop it from going to sleep’
This sounds very much like a statement about the handling of the myth of Prometheus throughout history. In fact, it is a quotation from Salman Rushdie’s The Satanic Verses . Either way, it provides an appropriate starting point for a Colloquium which seeks to identify and analyse aspects of the role of classical referents in Tony Harrison’s work. The verse-film Prometheus is a key text in this respect and so I wish to begin by trying to place the work in three different contexts:-
i. how figures in the myth have been explored in various artistic media
ii. the creation of Prometheus in the genres of tragedy and film
iii. the impact of Prometheus as a catalyst for interventionist work
My aim will be to identify ways in which Harrison’s Prometheus may and may not mesh with other examples of the treatment of the myth and to consider its special contribution to representations of Greek mythology and tragedy today
