Fungal stress biology: A preface to the Fungal Stress Responses special edition

There is currently an urgent need to increase global food security, reverse the trends of increasing cancer rates, protect environmental health, and mitigate climate change. Toward these ends, it is imperative to improve soil health and crop productivity, reduce food spoilage, reduce pesticide usage by increasing the use of biological control, optimize bioremediation of polluted sites, and generate energy from sustainable sources such as biofuels. This review focuses on fungi that can help provide solutions to such problems. We discuss key aspects of fungal stress biology in the context of the papers published in this Special Issue of Current Genetics. This area of biology has relevance to pure and applied research on fungal (and indeed other) systems, including biological control of insect pests, roles of saprotrophic fungi in agriculture and forestry, mycotoxin contamination of the food-supply chain, optimization of microbial fermentations including those used for bioethanol production, plant pathology, the limits of life on Earth, and astrobiology.

No War, No Peace: Northern Ireland after the Agreement

In 1998 a historic agreement, commonly known as the Belfast or Good Friday Agreement, formed the basis of a negotiated settlement for the future of Northern Ireland. Since that time the level of violence in Northern Ireland has reduced but many problematic issues related to governance, sectarianism, and community relations remain on the political agenda and have destabilized the post-peace accord environment. Many of these issues can be viewed as either causes or consequences of the protracted conflict in Northern Ireland. This special issue examines some of these issues from a political psychology perspective. Economic, political, social, and psychological factors that have supported and hindered progress towards peace and stability are considered. While the paramilitary ceasefires have remained intact and certain aspects of life in Northern Ireland have been transformed, the road to peace has been hindered by both political and psychological intransigence. This paper offers an opportunity to reevaluate conceptualisations of conflict and its management in chronic situations, where divisions are deeply embedded within societal structures and relationships, and consider factors that may act as barriers to the development of a lasting peace.

A Novel Multimodal Interface for Improving Visually Impaired People's Web Accessibility

This paper introduces a novel interface designed to help blind and visually impaired people to explore and navigate on the Web. In contrast to traditionally used assistive tools, such as screen readers and magnifiers, the new interface employs a combination of both audio and haptic features to provide spatial and navigational information to users. The haptic features are presented via a low-cost force feedback mouse allowing blind people to interact with the Web, in a similar fashion to their sighted counterparts. The audio provides navigational and textual information through the use of non-speech sounds and synthesised speech. Interacting with the multimodal interface offers a novel experience to target users, especially to those with total blindness. A series of experiments have been conducted to ascertain the usability of the interface and compare its performance to that of a traditional screen reader. Results have shown the advantages that the new multimodal interface offers blind and visually impaired people. This includes the enhanced perception of the spatial layout of Web pages, and navigation towards elements on a page. Certain issues regarding the design of the haptic and audio features raised in the evaluation are discussed and presented in terms of recommendations for future work.

Key issues in the study of new and alternative social movements in Spain: The Left, Identity and Globalizing Processes

This article highlights the importance of dedicating a whole special issue on New and Alternative Social movements in Spain. It sets the basis for this endeavour by emphasizing the importance of the 2004, unexpected, electoral victory of the Spanish socialists, and the subsequent satisfaction of the important demands promoted by certain social movements actors and Spanish society in general (the withdrawal of Spanish troops from Iraq, the cancellation of the National Hydrological Plan and the Legalization of same sex marriages. The view supported is that these developments signify the end of a protest cycle, which could have the same effect with the early 1980s socialist victory. After a discussion around the low associationalism that characterizes Spanish society and recent experience of authoritarianism, it is suggested that it is time for the study of new and alternative social movements in Spain and other south European societies to move beyond the emphasis on exceptionality but appreciate differences by focusing on the available political opportunities and the identity of social movement actors. The remainder of the article is dedicated to introducing the contributing articles.

Consulting pupils in Assessment for Learning classrooms: the twists and turns of working with students as co-researchers

This is an invited paper to a special issue on pupil voice focusing on methodological issues arising from the ESRC/TLRP project on consulting pupils about assessment practices in their classrooms. The issue of consulting pupils about assessment has rarely been researched before but what this article illustrates are some of the difficulties, tensions and positive outcomes of engaging with students as researchers within a nationally funded (and therefore externally driven), university-based project. This study adds considerably to the body of knowledge in this area by engaging students in the process as researchers in different capacities within the project. Issues discussed include the use of student advisory groups, ethical negotiation, students undertaking videotaped classroom observations and their subsequent role in co-interpreting video excerpts and visual images. The paper has attracted considerable interest already through the ESRC pupil seminar series forum and also from a prior paper presentation to the European Educational Research Association in September 2006 in Switzerland to the Childrens' Rights SIG becasue of researchers' current interests in embedding democratic principles and practices within research with children and young people.

The design of a navigation guidance and control system for an unmanned surface vehicle for environmental monitoring

Maintaining the ecosystem is one of the main concerns in this modern age. With the fear of ever-increasing global warming, the UK is one of the key players to participate actively in taking measures to slow down at least its phenomenal rate. As an ingredient to this process, the Springer vehicle was designed and developed for environmental monitoring and pollutant tracking. This special issue paper highlighted the Springer hardware and software architecture including various navigational sensors, a speed controller, and an environmental monitoring unit. In addition, details regarding the modelling of the vessel were outlined based mainly on experimental data. The formulation of a fault tolerant multi-sensor data fusion technique was also presented. Moreover, control strategy based on a linear quadratic Gaussian controller was developed and simulated on the Springer model.
Gaussian controller is developed and simulated on the Springer model.

The control and learning of patterns of interlimb coordination: past and present issues in normal and disordered control

The present paper provides a historical note on the evolution of the behavioral study of interlimb coordination and the reasons for its success as a field of investigation in the past decades. Whereas the original foundations for this field of science were laid down back in the seventies, it has steadily grown in the past decades and has attracted the attention of various scientific disciplines. A diversity of topics is currently being addressed and this is also expressed in the present contributions to the special issue. The main theme is centered on the brain basis of interlimb coordination. On the one hand, this pertains to the study of the control and learning of patterns of interlimb coordination in clinical groups. On the other hand, basic neural approaches are being merged together with behavioral approaches to reveal the neural basis of interlimb coordination. (C) 2002 Elsevier Science B.V.
