Factors shaping the evolution of electronic documentation systems

The main goal is to prepare the space station technical and managerial structure for likely changes in the creation, capture, transfer, and utilization of knowledge. By anticipating advances, the design of Space Station Project (SSP) information systems can be tailored to facilitate a progression of increasingly sophisticated strategies as the space station evolves. Future generations of advanced information systems will use increases in power to deliver environmentally meaningful, contextually targeted, interconnected data (knowledge). The concept of a Knowledge Base Management System is emerging when the problem is focused on how information systems can perform such a conversion of raw data. Such a system would include traditional management functions for large space databases. Added artificial intelligence features might encompass co-existing knowledge representation schemes; effective control structures for deductive, plausible, and inductive reasoning; means for knowledge acquisition, refinement, and validation; explanation facilities; and dynamic human intervention. The major areas covered include: alternative knowledge representation approaches; advanced user interface capabilities; computer-supported cooperative work; the evolution of information system hardware; standardization, compatibility, and connectivity; and organizational impacts of information intensive environments

The Hierarchic treatment of marine ecological information from spatial networks of benthic platforms

Measuring biodiversity simultaneously in different locations, at different temporal scales, and over wide spatial scales is of strategic importance for the improvement of our understanding of the functioning of marine ecosystems and for the conservation of their biodiversity. Monitoring networks of cabled observatories, along with other docked autonomous systems (e.g., Remotely Operated Vehicles [ROVs], Autonomous Underwater Vehicles [AUVs], and crawlers), are being conceived and established at a spatial scale capable of tracking energy fluxes across benthic and pelagic compartments, as well as across geographic ecotones. At the same time, optoacoustic imaging is sustaining an unprecedented expansion in marine ecological monitoring, enabling the acquisition of new biological and environmental data at an appropriate spatiotemporal scale. At this stage, one of the main problems for an effective application of these technologies is the processing, storage, and treatment of the acquired complex ecological information. Here, we provide a conceptual overview on the technological developments in the multiparametric generation, storage, and automated hierarchic treatment of biological and environmental information required to capture the spatiotemporal complexity of a marine ecosystem. In doing so, we present a pipeline of ecological data acquisition and processing in different steps and prone to automation. We also give an example of population biomass, community richness and biodiversity data computation (as indicators for ecosystem functionality) with an Internet Operated Vehicle (a mobile crawler). Finally, we discuss the software requirements for that automated data processing at the level of cyber-infrastructures with sensor calibration and control, data banking, and ingestion into large data portals.Peer ReviewedPostprint (published version

Balancing e-lectures with podcasts: a case study of an undergraduate engineering module

The work described in this paper is based on an engineering module that has run for six years (each academic year since 2004). The module is run online although the learners are campus-based students. This has provided an unusual opportunity to compare the same students’ experiences of on-campus and online courses. The course comprises a rich online environment including e-lectures, podcasts, video clips, website links, animations, background reading, formative quizzes, summative assignments and discussion boards. The e-lectures comprise a PowerPoint-like screen with a spoken audio track and other facilities, including a rolling transcript, video controls (for stopping, pausing and rewinding) and a search facility. Each e‑lecture is short (a maximum of ten minutes) and links to some of the learning materials (e.g. video clips and formative quizzes). The podcasts are mp3 audio files, each lasting approximately ten minutes, and are produced weekly and published through the virtual learning environment. This paper presents a pedagogical model that has been designed to develop a structure for combining these virtual learning elements and considers some of the opportunities provided by such innovative approaches for the enhancement of engineering teaching at undergraduate level. It presents research findings on student learning outcomes and provides suggestions for adopting the design for learning model presented in the paper
