The trapped geothermal heat in the infinite rock mass through which mine tunnels are excavated is a great threat to the safety of personnel and mine operating equipment in deep underground hot mines. In order to lessen the temperature inside the tunnel a considerable amount of energy is being spent by the way of using ventilation and cooling systems to dissipate the heat. However, operational costs of the system rise quite considerably, especially as the mines get deeper. Shotcrete is used both as a structural lining and as an effective insulation to reduce the heat load on the ventilation and cooling system within such tunnels. The paper aims to discuss these issues.

In order to analyse this problem of heat flow and thermal stresses and their time dependent pattern, several cylindrical models, in both analytical and numerical forms, are discussed and compared in this paper.

This study shows the validation of ABAQUS® software to predict the time dependent temperature and the thermal stresses in mine tunnels through the comparisons with the available analytical models. Further, thermal insulation effects of shotcrete are also evaluated with these theoretical models and it is found that all the models gave results in close agreements with one another.

Therefore, this study provides the theoretical proof for advantages in applying shotcrete as the thermal insulation layer in underground mines.

Purpose – Drawing on the currently available research, the authors explore the effectiveness of programs aimed at reducing re-engagement into terrorism, otherwise known as “deradicalization.”

Methodology/Approach – Our approach is descriptive. The authors support their argument with findings from a wide range of studies on these phenomena for the purposes of stimulating discussion.

Findings – Though scientific research on deradicalization remains nascent, there is sufficient promise in emerging findings to support a case for the effectiveness of deradicalization – in short, deradicalization programs can be effective, but just not for everyone.

Originality/Value – Popular accounts characterize deradicalization in a simplistic, binary fashion – they are judged to be either effective or ineffective. The current reality is consistent with some of the earliest conceptual discussion – that is, deradicalization programs do not offer a one-size fits all solution, they cannot work for everyone, and they are of immense practical benefit in some cases. The authors’ fundamental argument is that deradicalization initiatives warrant continued investment.

This article concerns the preparation and delivery of a part of an existing postgraduate records management course to a sample of records management practitioners at a distance. The project was a pilot study for the subsequent development of a distance learning course in records management in the Department of Information and Library Management at the University of Northumbria at Newcastle. The objectives were to investigate the practitioners' learning experience by analysing their thoughts and feelings recorded in a diary, to assess the suitability of existing learning materials and to identify appropriate delivery methods for different types of materials. Models of both learning and writing distance learning materials were adopted from the literature. Paper, audio and electronic materials were developed. The results will be used to make recommendations for developing the entire course.

AIP and FIZ Karlsruhe renew agreement. The American Institute of Physics (AIP), and Fachinformationszentrum Energie, Physik, Mathematik GmbH of Karlsruhe (FIZ Karlsruhe) in the Federal Republic of Germany, have announced the renewal of a seven‐year‐old agreement on scientific communications. The renewed agreement provides for improved international access to Physics Briefs, the computerised database of physics information.

Purpose – This chapter provides an overview of the book and discusses student diversity and institutional responses.

Methodology/approach – The chapter draws together literature and conceptual thinking about what student diversity is. It then analyses the drivers for increased diversity within higher education in the case studies in this book. Alternative approaches to diversity are presented, drawing on a synthesis of approaches identified in the literature. Finally, the chapter provides a summary of the other chapters and the associated case studies.

Findings – The chapter finds that diversity incorporates difference across a number of dimensions: education, personal disposition, current circumstances and cultural heritage. There are a wide range of reasons prompting institutions to recruit a diverse student population: a commitment to social justice, expansion and access to new markets, tapping the pool of talent, enhancing the student experience, national and/or regional policy, funding incentives, conforming with equality legislation, institutional research and personal commitment of staff. Institutions can respond to diversity in different ways. The idealised types are: altruistic (no institutional change), academic (little or no change), utilitarian (special access and additional support mechanisms) and transformative (positive view of diversity resulting in institutional development).

Research limitations – This chapter draws largely on the author's work in England and the United Kingdom and the case studies presented in this book.

Practical implications – This chapter is important as an introduction to the book, and providing frameworks to think about diversity.

Social implications – The framework for institutional change assists institutions to critically consider the response they make to a more diverse student population.

Originality/value – The paper provides original perspectives to conceptualising and responding to diversity.
