Methods of Obtaining Instantaneous Modulus of Viscoelastic Solids Using Displacement-Controlled Instrumented Indentation with Axisymmetric Indenters of Arbitrary Smooth Profiles

We derive a relationship between the initial unloading slope, contact depth, and the instantaneous relaxation modulus for displacement-controlled indentation in linear viscoelastic solids by a rigid indenter with an arbitrary axisymmetric smooth profile. While the same expression is well known for indentation in elastic and in elastic-plastic solids, we show that it is also true for indentation in linear viscoelastic solids, provided that the unloading rate is sufficiently fast. When the unloading rate is slow, a "hold" period between loading and unloading can be used to provide a correction term for the initial unloading slope equation. Finite element calculations are used to illustrate the methods of fast unloading and "hold-at-the-maximum-indenter-displacement" for determining the instantaneous modulus using spherical indenters.

Effective Assessment in a Digital Age

What contribution can technology make to ensuring that assessment and feedback processes are agile, streamlined and capable of promoting high-quality learning? Effective Assessment in a Digital Age, one in a series of Effective Practice guides, draws on recent JISC reports and case studies depicting different contexts and modes of learning to explore the relationship between technology enabled assessment and feedback practices and meaningful, well-supported learning experiences.

Effective Practice with e-Portfolios

Effective Practice with e-Portfolios, one in a series of Effective Practice guides, uses the outcomes of recent significant projects and examples from current practice to explore how e-portfolios can add value to personalised and reflective models of learning. Drawing on the work of key national agencies and organisations and on excellent practice and recent initiatives by institutions and professional bodies, the guide illustrates a wide variety of e-portfolio use across further, higher and continuing education.

Designing Spaces for Effective Learning: A guide to 21st century learning space design

Increasing investment in estate and learning technologies, combined with the need for more cost-effective space utilisation, is making it increasingly important for senior managers to keep abreast of new thinking about the design of technology-rich learning spaces. Designing Spaces for Effective Learning, one of a series of guides, was launched at the JISC Conference 2006 which helped to meet this need. A visually-rich publication, it was designed to promote better understanding of what makes an effective design for the 21 century and to summarise the key points to consider when approaching a refurbishment or new-build project. The publication takes the reader on a ’walk through’ an educational institution, exploring the relationship between learning technologies and innovative examples of physical space design at each stage of the journey. Discussion of the key points is illustrated by ten case studies from further and higher education, and floor plans from AMA Alexi Marmot Associates, architects and space planners, which provide up-to-date guidelines on the integration of technologies into teaching and learning accommodation.

Effective Practice in a Digital Age

Effective Practice in a Digital Age is designed for those in further and higher education who aim to enhance the student learning experience through apt and imaginative uses of technology. A visually rich publication, Effective Practice in a Digital Age outlines key aspects of designing learning in a technology-rich context and is structured to address the needs of experienced practitioners as well as those new to technology-based learning and teaching – the ten newly researched case studies offer a choice of pathways reflecting the diversity of approaches taken by practitioners in current UK practice.

Genetic improvement and effective dissemination: keys to prosperous and sustainable aquaculture industries

There is an increasing demand for fish in the world due to a growing population, better economic situation in some sectors, and greater awareness of health issues in relation to food. Since capture fisheries have stagnated, fish farming has become a very fast growing food production system. In this presentation, the author gives an overview of the technologies that are available for genetic improvement of fish, and briefly discuss their merit in the context of a sustainable development. He also discusses the essential prerequisites for effective dissemination of improved stock to farmers. It is concluded that genetic improvement programs based on selective breeding can substantially contribute to sustainable fish production systems. Furthermore, if such genetic improvement programs are followed up with effective dissemination strategies, they can result in a positive impact on farmers' incomes.
