Exterior Differential Systems and Euler-Lagrange Partial Differential Equations (Chicago Lectures in Mathematics) by Phillip Griffiths, Daniel Grossman, Robert L. Bryant English | July 1, 2003 | ISBN: 0226077942 | 216 pages | PDF | 24 Mb In Exterior Differential Systems, the authors present the results of their ongoing development of a theory of the geometry of differential equations, focusing especially on Lagrangians and Poincaré-Cartan forms. They also cover certain aspects of the theory of exterior differential systems, which provides the language and techniques for the entire study. Because it plays a central role in uncovering geometric properties of differential equations, the method of equivalence is particularly emphasized. In addition, the authors discuss conformally invariant systems at length, including results on the classification and application of symmetries and conservation laws. The book also covers the Second Variation, Euler-Lagrange PDE systems, and higher-order conservation laws.  Extended Reality Solutions to Support Older Adults: Potential Applications for Users With and Without Cognitive Impairments (Synthesis Lectures on Technology and Health) by Walter R. Boot, Andrew Dilanchian, Saleh Kalantari English | October 29, 2024 | ISBN: 3031692195 | 95 pages | True ePUB, PDF | 13 Mb This book explores one way in which recent hardware and software advances have placed humanity on the precipice of a significant shift in how technology can shape our interactions with the world around us: the application of transformative extended reality (XR) technology solutions to support the health, wellness, quality of life, and independence of older adults living with and without cognitive impairments. The book provides an overview of the state-of-the art research on XR-based solutions utilizing virtual reality (VR) and augmented reality (AR), challenges that can addressed with these technologies, evidence to date on the efficacy of these solutions, and the nature of these solutions and challenges to their implementation. It explores practical ways XR can be integrated into health and lifestyle maintenance activities for older populations in a diversity of situations through thematic chapters using realistic personas and scenarios. These thematic chapters are organized around the AGE-WELL Challenge Area topics, including staying connected, healthy lifestyles and wellness, mobility, and cognitive health, as well as an additional emphasis on leisure. Other chapters provide guidance on important issues to consider when designing XR-based solutions for older adults, how to evaluate and test XR solutions, the implementation of the user-centered design process, and the book concludes by highlighting unanswered questions and future research directions. This book approaches XR for older adults with and without cognitive impairments from the authors' diverse research backgrounds in psychology, engineering, gerontology, and design. It will be of interest to academic and industry professionals as well as care providers considering the potential for XR interventions now and in the future.  Expressive Iteration by Kenny K.N. Chow English | February 14, 2025 | ISBN: 1032489243 | 268 pages | MOBI | 8.78 Mb A ground-breaking guide to thinking about how routine activities can be designed and innovated to develop narrative meaning and a sense of purpose.  Exploring the Pedagogy of Learning and Playing Outdoors (Towards an Ethical Praxis in Early Childhood) by Mehmet Mart, Georgia Gessiou, Jane Waters-Davies English | February 14, 2025 | ISBN: 1032870184 | 162 pages | True ePUB, PDF | 3.11 Mb Focusing on the empirical evidence base for pedagogical decisions taken when children are playing and learning outside, this groundbreaking book examines the intention and purpose of children's outdoor playful activity and the associated issues of pedagogy. Chapters address questions about the role of the adult in children's learning outside in a manner that is inclusive in nature, by recognising the varied contexts in which children's playful activity outside takes place. Reflecting multiple cultural contexts, chapters consider social and physical aspects to ensure value systems are visible and critically considered. The book acknowledges the continuum of children's outdoor experience from highly structured activity to free play outside. It also examines the existing evidence base about children's outdoor play, including a consideration of how adults construct and respond to children's playful activity outside to realise the associated benefits. With reference throughout to many international contexts, this book reminds us of the shaping force of cultural practices and beliefs about children's playful activity outside and will be of interest to undergraduate and postgraduate audiences studying early childhood education.  Exploring Nationalism: Identifying its forms, particularly those which lead to War and Mayhem by Andrew Sangster English | August 30, 2025 | ISBN: 1036130916 | 208 pages | MOBI | 8.09 Mb "...examines how patriotism can warp into aggressive nationalism and its close cousin irredentist nationalism." - Historical Miniatures Gaming Society  Exploring Math-Focused Careers by Terri Dougherty English | 2025 | ISBN: 1678207969 | 64 Pages | PDF | 3.2 MB  Exploring Digital Ethnography by Natalie Underberg-Goode, Marty Otañez English | July 23, 2025 | ISBN: 1032436980 | 168 pages | MOBI | 6.49 Mb Exploring Digital Ethnography: From Principles to Practice places digital ethnography within the context of the production of multimedia, multisensory "research-creation" pieces using a variety of methods, tools, and techniques.  Exploring Bilingualism in Education: A Machine-Generated Literature Overview by Udaya Muthyala English | December 26, 2024 | ISBN: 981979353X | 390 pages | True ePUB, PDF | 3.38 Mb This book presents a comprehensive introduction to the field of bilingualism and multilingualism with focus on education. It compiles various sub-themes such as minority and majority languages, childhood bilingualism, and the historical aspects of bilingualism. Each chapter is carefully structured and includes clear themes with introductory notes by the editor. The main focus is on the cognitive development of bilinguals and how they promote cultural diversity, presenting how bilingual education and second language teaching within the socio-political and multicultural landscape are interconnected. It discusses significant concepts such as translanguaging, an innovative approach that transcends traditional language boundaries, and the role of Multilingual Education (MLE) in shaping the future of learning. Research also focusses on macro-level issues, such as globalization and minority language preservation, and micro-level strategies for bilingual classrooms. In addition, it explores topics such as Dual Language schools, the economic benefits of bilingualism, and debates on language loss and bilingual education policy in different countries. These well-organized topics promote a holistic understanding of bilingualism and encourage a positive view of linguistic diversity and its role in creating a more inclusive, multicultural world. For educators, researchers and language enthusiasts, it is an invaluable resource that provides a thorough understanding of the nuances of bi/multilingual education.
