These are the proceedings of an international meeting hosted by the Royal Observatory, Edinburgh, to commemorate the 30th anniversary of the dedication of the UKIRT, the United Kingdom InfraRed Telescope.

The volume comprises 31 professional level papers. The first part of the book has 10 thorough reviews of the conception, design and build of the telescope, as well as accounts of some its key instruments such as IRCAM (the common-user infrared camera), CGS4 (the fourth Cooled Grating Spectrometer) and the Wide Field Camera. The second part of the book comprises 14 reviews of scientific achievements during its twenty years of visitor mode operations. The final part of the book is a series of 7 reviews of the results from the multiple surveys being done as part of UKIDSS (UKIRT Infrared Deep Sky Survey).

The authors are all experts in their respective fields, for example instrument scientists, operations staff and leading astronomers.

The battle to preserve the environment is only just beginning – organisations and governments cannot underestimate the public outcry for cleaner environments and an end to increases in global warming. The Circular Economy has been able to tap into the current zeitgeist and is being coveted by many academic disciplines. Offering a detailed overview of what is required to move towards a circular economy by providing a series of cases alongside each chapter that illustrate practice in relation to theory, Maguire and Robson deliver a lens through which academics and students can explore what is emerging as state of the art. The chapters contain a critical and balanced treatment of theory and practice on the subjects of sustainable development and the circular economy, setting out and evaluating the theoretical landscape alongside a grand narrative drawn from systems thinking and the environmental, social, and governance paradigms. For students, academics and practitioners, Sustainable Development through Global Circular Economy Practices is a go-to book with original insights from a theoretical perspective about how the global economy integrates, and how this integration can be leveraged to move practice toward sustainable practice.

The Reflective Leader brings together theory and core concepts through reflective practice, reflexivity, and experiential learning to crystallize current thinking regarding introspection and contextual intelligence in understanding and improving the effectiveness of leaders. Beginning with an understanding how leaders learn through reflection, researchers will be introduced to the philosophical and historical roots that underpin reflective learning. Chapters then examine the leadership journey, learning and un-learning through reflective practice, the reflexive practicum, practice and praxis, creativity and reflection, and action learning and reflection. Featuring interviews with a wide range of practitioners that present reflections on critical incidents and learning episodes, Robson provides a practical narrative to underpin theoretical discovery. "Reflexivity in practice" connects the experience of practitioners, synthesising theory, practice setting and personal experiential learning to support and inform researchers, students, and reflective professionals.
