Knowledge representation with ontologies: present challenges future possibilities

Ontologies have become the knowledge representation medium of choice in recent years for a range of computer science specialities including the Semantic Web, Agents, and Bio-informatics. There has been a great deal of research and development in this area combined with hype and reaction. This special issue is concerned with the limitations of ontologies and how these can be addressed, together with a consideration of how we can circumvent or go beyond these constraints. The introduction places the discussion in context and presents the papers included in this issue.

Whither critical pedagogy in the neo-liberal university today? Two UK practitioners' reflections on constraints and possibilities

This paper, based on the reflections of two academic social scientists, offers a starting point for dialogue about the importance of critical pedagogy within the university today, and about the potentially transformative possibilities of higher education more generally. We first explain how the current context of HE, framed through neoliberal restructuring, is reshaping opportunities for alternative forms of education and knowledge production to emerge. We then consider how insights from both critical pedagogy and popular education inform our work in this climate. Against this backdrop, we consider the effects of our efforts to realise the ideals of critical pedagogy in our teaching to date and ask how we might build more productive links between classroom and activist practices. Finally, we suggest that doing so can help facilitate a more fully articulated reconsideration of the meanings, purposes and practices of HE in contemporary society. This paper also includes responses from two educational developers, Janet Strivens and Ranald Macdonald, with the aim of creating a dialogue on the role of critical pedagogy in higher education.

Research possibilities for organisational cognitive neuroscience

In this article, we identify research possibilities for organizational cognitive neuroscience that emerge from the papers in this special issue. We emphasize the intriguing finding that the papers share a common theme-the use of cognitive neuroscience to investigate the role of emotions in organizational behavior; this suggests a research agenda in its own right. We conclude the article by stressing that there is much yet to discover about how the mind works, especially in organizational settings.

Possibilities and limitations of coded aperture imaging

We have simulated the performance of various apertures used in Coded Aperture Imaging - optically. Coded pictures of extended and continuous-tone planar objects from the Annulus, Twin Annulus, Fresnel Zone Plate and the Uniformly Redundant Array have been decoded using a noncoherent correlation process. We have compared the tomographic capabilities of the Twin Annulus with the Uniformly Redundant Arrays based on quadratic residues and m-sequences. We discuss the ways of reducing the 'd. c.' background of the various apertures used. The non-ideal System-Point-Spread-Function inherent in a noncoherent optical correlation process produces artifacts in the reconstruction. Artifacts are also introduced as a result of unwanted cross-correlation terms from out-of-focus planes. We find that the URN based on m-sequences exhibits good spatial resolution and out-of-focus behaviour when imaging extended objects.

Niederdeutsch im Internet. Möglichkeiten und Grenzen computervermittelter Kommunikation für den Spracherhalt:possibilities and limitations of computer-mediated communication for language preservation

Der vorliegende Beitrag untersucht die Frage, in welchem Maße sich Institutionen, die niederdeutsche Kulturszene und individuelle Sprecher des Niederdeutschen moderne Kommunikationstechnologien wie das Internet zunutze machen und ob computervermittelte Kommunikation helfen kann, dem Rückgang des Niederdeutschen Einhalt zu gebieten. Die grundsätzliche Herangehensweise ist eine soziolinguistische, die das Internet als sozialen Handlungsraum versteht, in dem Individuen und Institutionen kommunizieren. Für eine derartige Perspektive stehen weniger das Medium oder das Genre im Mittelpunkt des Interesses als vielmehr das kommunizierende Individuum und die Sprachgemeinschaft, in diesem Fall die virtuelle Sprachgemeinschaft. Based on studies that analyse the potential of computer-mediated communication (cmc) to help fight language shift in lesser-used languages, this paper discusses the situation of Low German in Northern Germany. Over the last three decades, Low German has lost more than half of its active speakers. The article raises the question of whether and, if so, how Low German speakers make use of cmc to stem this tide. Following a sociolinguistic approach focussed on the individual speakers who use the Internet as a space for social interaction, it gives an overview of the discursive field of Low German on the internet and analyses in detail the most popular Low German discussion board. It shows that one of the main obstacles to a more successful use of cmc can be found in speakers' complex attitude toward written Low German. © Franz Steiner Verlag Stuttgart.

Metaphor in translation:possibilities for process research

This paper explores potential benefits of closer interaction between metaphor studies and translation process research. It presents some developments within Translation Studies which make use of conceptual metaphor theory and illustrates some process research methods for investigating metaphors. The paper considers a number of methodological recommendations and argues that of greatest importance is the need to take full account of insights from metaphor studies and associated disciplines. Another important potential innovation is the use of a multilingual approach in respect of both product- and process-oriented studies in order to increase both the amount and generality of data available for analysis. Thirdly, it is important to extend and complement the current ST-oriented approach. The paper concludes by suggesting some options for triangulating data gathered through a combination of methods.

Cross-institutional development of an online open course for educators:confronting current challenges and imagining future possibilities

The Global Dimensions in Higher Education module is a fully online open course for educators, jointly developed by three UK universities through a process of consultation and inquiry involving colleagues within the global education sector. The purpose of the module is two-fold. Firstly, to engage academics within and beyond the partner institutions in a critical exploration of transnational and global issues within higher education. Secondly, to provide the project partners with an opportunity to understand and address the challenges of jointly developing and delivering an online course that is to be offered both openly as well as integrated within credit-bearing and continued professional development provision for academics in the partner institutions. This short paper describes progress to date in developing the Global Dimensions in Higher Education module, our current activity focused on validating and implementing the module, and lessons learned to be considered for the collaborative development of open online courses.

The possibilities and limits of contestation in times of 'urban austerity'

This paper seeks to provide a conceptual framework in which to examine the social practices of contemporary austerity programmes in urban areas, including how these relate to different conceptions of crisis. Of current theoretical interest is the apparent ease with which these austerity measures have been accepted by urban governing agents. In order to advance these understandings we follow the recent post-structuralist discourse theory ‘logics’ approach of Glynos and Howarth (2007), focusing on the relationship between hegemony, political and social logics, and the subject whose identificatory practices are key to understanding the form, nature and stability of discursive settlements. In such thinking it is not only the formation of discourses and the mobilisation of rhetoric that are of interest, but also the manner in which the subjects of austerity identify with these. Through such an approach we examine the case of the regeneration/economic development and planning policy area in the city government of Birmingham (UK). In conclusion, we argue that the logics approach is a useful framework through which to examine how austerity has been uncontested in a city government, and the dynamics of acquiescence in relation to broader hegemonic discursive formations.

Collaborating to achieve corporate social responsibility and sustainability? Possibilities and problems

Purpose: The purpose of this paper is to investigate the possibilities and problems for collaboration in the area of corporate social responsibility (CSR) and sustainability. The paper explores the nature and concept of collaboration and its forms, and critically evaluates the potential contribution a collaborative approach between agencies might offer to these agendas. Design/methodology/approach: The paper explores different forms of research on collaboration, together with a UK Government report on collaboration, to evaluate how the issue is addressed in theory and practice. Findings: Sustainable development creates extensive challenges for a wide range of agencies, including governments, non-governmental organizations, businesses and civil society. It is unlikely, however, that solutions will be found in any one quarter. Collaboration between agencies in some form would seem a logical step in supporting measures towards a more responsible and environmentally sustainable global economy. Originality/value: The paper offers new insights into developing a research and praxis agenda for collaborative possibilities towards the advancement of CSR and sustainability. © Emerald Group Publishing Limited.
