Spectral imaging has many applications, from methane detection using satellites to disease detection on crops. However, spectral cameras remain a costly solution ranging from 10 thousand to 100 thousand euros for the hardware alone. Here, we present a low-cost multispectral camera (LC-MSC) with 64 LEDs in eight different colors and a monochrome camera with a hardware cost of 340 euros. Our prototype reproduces spectra accurately when compared to a reference spectrometer to within the spectral width of the LEDs used and the ±1σ variation over the surface of ceramic reference tiles. The mean absolute difference in reflectance is an overestimate of 0.03 for the LC-MSC as compared to a spectrometer, due to the spectral shape of the tiles. In environmental light levels of 0.5 W m−2 (bright artificial indoor lighting) our approach shows an increase in noise, but still faithfully reproduces discrete reflectance spectra over 400 nm–1000 nm. Our approach is limited in its application by LED bandwidth and availability of specific LED wavelengths. However, unlike with conventional spectral cameras, the pixel pitch of the camera itself is not limited, providing higher image resolution than typical high-end multi- and hyperspectral cameras. For sample conditions where LED illumination bands provide suitable spectral information, our LC-MSC is an interesting low-cost alternative approach to spectral imaging.

This is the ‘Developing a reflection tool’ manual. The manual provides points of reference for the development of a reflection tool for interventions and more general approaches in children’s services. A team can use the fmanual to get to work itself on creating a tool to give each other feedback on the quality of the implementation of the intervention or approach. This is important, as we know that the quality of the care provided is directly related to the outcomes for clients and that learning from one another contributes to that quality.

This book fills an important gap in the sport governance literature by engaging in critical reflection on the concept of ‘good governance’. It examines the theoretical perspectives that lead to different conceptualisations of governance and, therefore, to different standards for institutional quality. It explores the different practical strategies that have been employed to achieve the implementation of good governance principles. The first part of the book aims to shed light on the complexity and nuances of good governance by examining theoretical perspectives including leadership, value, feminism, culture and systems. The second part of the book has a practical focus, concentrating on reform strategies, from compliance policies and codes of ethics to external reporting and integrity systems. Together, these studies shed important new light on how we define and understand governance, and on the limits and capabilities of different methods for inducing good governance. With higher ethical standards demanded in sport business and management than ever before, this book is important reading for all advanced students and researchers with an interest in sport governance and sport policy, and for all sport industry professionals looking to improve their professional practice.
