Agroecological Transitions: From Theory to Practice in Local Participatory Design by Jacques-Eric Bergez,Elise Audouin,Olivier Therond Pdf
This Open Access book presents feedback from the ‘Territorial Agroecological Transition in Action’- TATA-BOX research project, which was devoted to these specific issues. The multidisciplinary and multi-organisation research team steered a four-year action-research process in two territories of France. It also presents: i) the key dimensions to be considered when dealing with agroecological transition: diversity of agriculture models, management of uncertainties, polycentric governance, autonomies, and role of actors’ networks; ii) an operational and original participatory process and associated boundary tools to support local stakeholders in shifting from a shared diagnosis to a shared action plan for transition, and in so doing developing mutual understanding and involvement; iii) an analysis of the main effects of the methodology on research organisation and on stakeholders’ development and application; iv) critical analysis and foresights on the main outcomes of TATA-BOX, provided by external researchers.
Designing solutions for transitions from childhood to adult life for youth with disabilities: A guide for service providers, organizations, and system leaders by Evidence to Care, Holland Bloorview Kids Rehabilitation Hospital,Transitions Strategy Team, Holland Bloorview Kids Rehabilitatio Hospital Pdf
This guide offers a blueprint for co-designing and refreshing evidence-informed, needs-based solutions. Written for service providers, organizations, and system leaders who support transitions to adult life for young people with disabilities, across healthcare, community, education, and social service sectors. The digestible content and visually appealing graphic design makes the guide easy to read and navigate, allowing you to choose which sections are most relevant to you. Start with an introduction to using evidence and best practices in transition practice. Then read about our transformative approach to solution design, presented in four key tenets (Frameworks, Solution-focused approach, Human centered design, and Collaboration). To see how we put these tenets in action, skip ahead to four examples of transitions solutions implemented at Canada’s largest pediatric rehabilitation hospital (Holland Bloorview Kids Rehabilitation Hospital). To action the tenets in your own practice, use the evidence-informed and practice-based supporting materials in the two appendices. Each section contains valuable resources, tools, and tips for your practice.
The Railway Track and Its Long Term Behaviour by Konstantinos Tzanakakis Pdf
A proper quality of a track and other infrastructure objects represents a basic requirement for train safety and punctuality. Most of the physical systems and their components deteriorate over time. This affects performance and may lead to failures. Albert Einstein said, “You have to learn the rules of the game. And then you have to play better than anyone else.” Only if we understand how the whole system works, taking into account its imperfections and how they influence its quality and performance will we be able to learn the rules of the game and “play better.” The book provides the readers with the necessary functional knowledge of track behaviour and comprehensively covers the function of the various track components, their interaction as elements of the track system, as well as the interaction of the track with railway vehicles. By presenting important tools for a deep understanding of track-behaviour this book aims to be a reference guide for infrastructure managers and to help them to find ways improving track quality for optimum long-term behaviour.
Design of High-Speed Railway Turnouts by Ping Wang Pdf
High-speed turnouts, a key technology for high-speed railways, have a great influence on the safe and stable running of high-speed trains. Design of High-Speed Railway Turnouts: Theory and Applications, comprehensively introduces the technical characteristics and requirements of high-speed turnouts, including design theories and methods of turnout layout geometry, wheel and rail relations, track stiffness, welded turnout, turnout conversion, turnout components, and manufacture and laying technologies of turnouts. Analyzing the operational problems of China’s high-speed turnout in particular, this book discusses the control of structure irregularity, state irregularity, geometrical irregularity and dynamic irregularity during the design, manufacture, laying, and maintenance of turnouts. At the end of this reference book, the author provides high-speed turnouts management methods, maintenance standards, testing and monitoring technology, and maintenance technology. Design of High-Speed Railway Turnouts: Theory and Applications will enable railway technicians all over the world to develop an in-depth knowledge of the design, manufacture, laying, and maintenance technology of high-speed turnouts. The first book in the world to focus explicitly on high-speed turnouts, including design, construction, maintenance and management of high speed turnouts Expounds the theory of vehicle-turnout system coupling dynamics in detail, aligning this with several examples of computation, and examines the results of dynamic experiments which validate the theory Written by Ping Wang, who is recognized as a leading researcher and main developer of high-speed turnouts in China

IT Outsourcing Part 1: Contracting the Partner by Gerard Wijers Pdf
As companies focus on the core specialisms, most will look to the benefits of outsourcing some, if not all, of the IT services required. The benefits include:cost-efficient operations;delivery of IT services at lower cost through economies of scale; improvements in time-to-market of IT solutions; improvements in capability andquality of IT service delivery.This essential guide looks at the procedures needed to achieve all these benefits when contracting an outsourcing partner. It explains the benefits of a well thought-out and practical approach to selecting a partner; a partner, indeed, whose performance may make or break an organization s delivery to market. This book is a key reference guide to anyone procuring IT services and also to those who are responsible for maintaining the contract once signed. By covering all aspects of the Outsourcing contracting process, its guidance will help reduce risks and miscommunication. In addition its approach to the Request for Proposal (also known as Invitation to Tender) shows how clarity at this stage can deliver significant benefits as the services go live in the operational phase.
