Transdisciplinary Science: A Path to Understanding the Interactions Among Ocean Acidification, Ecosystems, and Society

The global nature of ocean acidification (OA) transcends habitats, ecosystems, regions, and science disciplines. The scientific community recognizes that the biggest challenge in improving understanding of how changing OA conditions affect ecosystems, and associated consequences for human society, requires integration of experimental, observational, and modeling approaches from many disciplines over a wide range of temporal and spatial scales. Such transdisciplinary science is the next step in providing relevant, meaningful results and optimal guidance to policymakers and coastal managers. We discuss the challenges associated with integrating ocean acidification science across funding agencies, institutions, disciplines, topical areas, and regions, and the value of unifying science objectives and activities to deliver insights into local, regional, and global scale impacts. We identify guiding principles and strategies for developing transdisciplinary research in the ocean acidification science community.

Software Products for Modelling and Simulation in Materials Science

Models and software products have been developed for modelling, simulation and prediction of different correlations in materials science, including 1. the correlation between processing parameters and properties in titanium alloys and ?-titanium aluminides; 2. time–temperature–transformation (TTT) diagrams for titanium alloys; 3. corrosion resistance of titanium alloys; 4. surface hardness and microhardness profile of nitrocarburised layers; 5. fatigue stress life (S–N) diagrams for Ti–6Al–4V alloys. The programs are based on trained artificial neural networks. For each particular case appropriate combination of inputs and outputs is chosen. Very good performances of the models are achieved. Graphical user interfaces (GUI) are created for easy use of the models. In addition interactive text versions are developed. The models designed are combined and integrated in software package that is built up on a modular fashion. The software products are available in versions for different platforms including Windows 95/98/2000/NT, UNIX and Apple Macintosh. Description of the software products is given, to demonstrate that they are convenient and powerful tools for practical applications in solving various problems in materials science. Examples for optimisation of the alloy compositions, processing parameters and working conditions are illustrated. An option for use of the software in materials selection procedure is described.

Bystander Narratives: The Fiction of J.M. Coetzee and the Holocaust

J.M. Coetzee’s novels are suffused with a pervasive, though often oblique, Holocaust awareness. Direct references to the event and to the historical era to which it belongs, subtle stylistic and thematic echoes of Holocaust writing, and the recurrent mobilization of Holocaust imagery in Coetzee’s novels all contribute to suggest the significance of the event to the author’s work and thought. Providing Coetzee with a lens through which to view the contemporary situation, both local and global, the Holocaust offers Coetzee a means by which difficult and complex questions of ethics and historiographical truth may be approached. Above all, the Holocaust and its representation contribute to Coetzee’s exploration of the dilemmas of translating the traumatic lived experience of atrocity – including, but not limited to, life in apartheid South Africa – into narrative form. Taken as a whole, Coetzee’s oeuvre initially anticipates and later responds to, in characteristically oblique fashion, the narrative project(s) facing post-apartheid South Africa as the newly-democratic nation sought to make sense of its past through a variety of means, the most important of which was the country’s Truth and Reconciliation Commission. Implicitly challenging the TRC’s findings as well as its narrative assumptions, the Coetzean oeuvre accordingly invites being read as offering a continuous and evolving counter-narrative to the TRC and its construction of a narrative of the apartheid past for the post-apartheid nation. In utilizing the Holocaust, its representations, and the reception thereof to frame his response to apartheid, Coetzee implicates both in a critique of the Western model of modernity, suggesting, in the process, the importance of reconfiguring modernity in a more ethical shape.
