Developing a Graphical Route Information Panel (GRIP) for use on the UK motorway network. The first steps

This paper describes the initial stages of research to develop design guidelines and draft designs for Graphical Route Information Panels to be used on the UK motorway network to display traffic congestion information. The studies utilised a funnelling approach to initially capture the broad design principles involving all stakeholders and then narrow down the design options using a range of validation and evaluation activities to achieve the desired design guidelines. Guidance for graphical road based display design is presented along with a methodological approach for the implementation of new designs

Journey decision making: the influence on drivers of dynamic information presented on variable message signs

In many highways environments electronic media such as variable message signs are increasingly being used to provide drivers with up-to-date dynamic information in order to influence driving decision making during journeys. These decisions may be associated with strategic choices, such as route selection, or tactical decisions, such as driving at a certain speed, or altering driving style. This paper presents a study that used two methods - a scenario approach and a medium-fidelity driving simulator. Data from both methods are presented here and include decision making and driving performance data. These data provide an insight into the role of information and other contextual influences in decision making in the driving context specifically, but also has useful implications for the way in which information should be designed in other decision making contexts, such as travel using public transport, or supporting real-time complex control operations. The use of multiple data collection approaches also enabled data comparisons to be made, thus improving overall confidence in conclusions. The paper highlights the role of familiarity with information wording and context, level of detail, interpreted meaning, previous experience and contextual cues on trust in information and consequently behaviour in response to the information presented

Bioenergetic defects in muscle fibers of RYR1 mutant knock-in mice associated with malignant hyperthermia

Mutations in the skeletal muscle ryanodine receptor gene (RYR1) can cause susceptibility to malignant hyperthermia (MH), a potentially lethal genetic condition triggered by volatile anesthetics. MH is associated with hypermetabolism which has directed research interest into oxidative phosphorylation (OXPHOS) and muscle bioenergetics. The most common cause of MH in the United Kingdom is the c.7300G>A RYR1 variant, which is present in ~16% of MH families. Our study focuses on the MH susceptible G2435R-RYR1 knock-in mouse model, which is the murine equivalent of the human c.7300G>A genotype. Using a combination of transcriptomics, protein expression and functional analysis, we investigated adult muscle fiber bioenergetics in this mouse model. RNA sequencing data showed reduced expression of genes associated with mitochondria and fatty acid oxidation in RYR1 mutants when compared to wild-type (WT) controls. Mitochondrial function was assessed by measuring oxygen consumption rates in permeabilized muscle fibers. Comparisons between WT and homozygous G2435R-RYR1 mitochondria showed a significant increase in complex I-facilitated OXPHOS in mutant muscle. Furthermore, we observed a gene-dose specific increase in reactive oxygen species production in G2435R-RYR1 muscle fibers. Collectively these findings provide evidence of metabolic defects in G2435R-RYR1 knock-in mouse muscle under basal conditions. Differences in metabolic profile could be the result of differential gene expression in metabolic pathways, in conjunction with mitochondrial damage accumulated from chronic exposure to increased oxidative stress

Imagining technology-enhanced learning with heritage artefacts: teacher-perceived potential of 2D and 3D heritage site visualisations

Background: There is much to be realised in the educational potential of national and world heritage sites. Such sites need to be supported in sharing their resources with a wide and international public, especially within formal education. Two-dimensional (2D) and three-dimensional (3D) heritage site visualisations could serve this need. Our study focuses on the teacher-perceived possibilities and benefits for education around such visualisations. Purpose: We describe how a group of UK teachers perceive the potential of cross-curricular learning that could arise from an Italian world heritage site. The teachers commented on 2D visualisations of artefacts from this site, as well as the design of a 3D immersive environment to serve educational purposes. We consider as follows: (1) how the cross-curricular teaching potential of such resources is perceived, and (2) what design features of a 3D immersive environment teachers suggest are needed for educational explorations. Sample: We recruited 10 teachers from the Midlands region of the UK and carried out semi-structured interviews. Methods: Interviews were transcribed and a thematic analysis applied to the conversations. Questioning was grounded in the examination of 2D and 3D visual resources. This provoked cross-curricular and educational design thinking. Results: Teacher responses highlighted a wide range of cross-curricular possibilities. However, they expressed a more ‘assimilative’ than ‘accommodative’ approach when relating resources to the curriculum. Such ‘assimilation’ involved seeing the site artefacts as raw material for more instrumental ‘curriculum activities’ (e.g. within art and design, geography, maths or literacy) rather than a more accommodative approach whereby curricular disciplines were exercised to make new meaning from the artefacts. In relation to 3D technology design, most teachers highlighted three technology features that would render it well matched to educational practice and three educational benefits over non-3D immersive environments. Conclusions: Teachers can easily imagine a rich range of opportunities to utilise 2D and 3D heritage site artefacts within the curriculum. However, the largely assimilative nature of this cross-curricular appropriation suggests the value of providing more guidance and support to teachers in the interpretation and application of artefacts. Their design suggestions can usefully inform construction of educational features within 3D immersive technologies that support heritage site experiences

Patent information in a changing world: Perspectives from a major patent office

The patent information field is in a state of flux, caused by new tools and changing habits and philosophies. In this article a number of major issues arising from this situation are discussed, some ways in which the EPO is responding are described, and some ideas on future developments provided. Patents are increasingly rated as valuable assets, but is patent information, and especially bibliographic patent information, being treated with the same meticulousness as in the past? More people are searching than ever before. But are they squeezing out the information professional? What effect will the IPC reform, the arrival of XML and other developments have? By focussing on completeness, timeliness and correctness, can patent offices make a contribution to alleviate the situation? The author concludes that, more than ever before, it is important that expert patent information professionals ensure that their views and needs are communicated to both initial data suppliers, mainly patent offices, and to commercial database suppliers and hosts.Bibliographic information Patent information Commercial databases Internet databases Information professionals IPC reform Patent offices Completeness Timeliness Correctness
