This book introduces the emerging field of "Humane Artificial Intelligence", emphasizing the crucial importance of interdisciplinarity in developing AI systems aligned with human values and well-being. While traditional AI development has often prioritized efficiency and optimization, the book advocates a paradigm shift toward frameworks that integrate ethical principles, transparency, and human considerations at the heart of AI systems. It synthesizes research across four interconnected dimensions. First, it establishes foundational frameworks for human-AI relationships, exploring models of cognitive extension and philosophical debates from Turing to contemporary questions about machine meaning and intentionality. Second, it explores human creativity, cognition, and enhancement, revealing when human-AI combinations prove most effective, while raising questions about artificial consciousness and well-being. Third, it explores professional applications, demonstrating how integrating AI into workplace governance, mental healthcare, and diagnostic imaging requires careful attention to human expertise. Fourth, it addresses legal and regulatory frameworks, examining both ambitious visions for human-AI legislation and the practical challenges of regulating rapidly evolving technologies. By understanding the interdisciplinary dimension of human-AI interaction, we can develop technologies that respect human autonomy, enhance capabilities, promote well-being, and reflect our highest values.

The adoption of new technological paradigms has recently shifted part of the scholarship on religions towards new research questions. Such a new condition stimulates scholarly curiosity which needs to be effective and fertile matching with technological infrastructures and access to physical and digital sources and research means. ITSERR (Italian Strengthening of the ESFRI RI RESILIENCE) is a research project launched in 2022 with the goal of enhancing RESILIENCE, the European research infrastructure for the study of religions. Primary goal is to meet the evolving needs of its multidisciplinary scientific community and support the development of the national node of RESILIENCE. With the endorsement of new technological paradigms, the project is willing to play a pivotal role in enriching the diversity, quality and innovation of knowledge produced by the community of scholars investigating religions. The volume presents the first research and methodological outcomes achieved by the ITSERR team, composed of researchers in the humanities and information technologies.

Addicted: Big Tech and Little Minds is a powerful, eye, opening exploration of how childhood is being reshaped, rewired, and in many ways stolen by the digital world. This book pulls back the curtain on what really happens when children grow up immersed in smartphones, social platforms, endless scrolling, and technology designed to capture attention before minds are fully formed. Thoughtful, compelling, and backed by clear explanations, it reveals how childrens emotional wellbeing, mental health, social development, and identity are being shaped by forces far beyond their control. If youve ever wondered why children are more anxious, more distracted, more lonely, or more exhausted than ever before, this book explains it. From the rise of screen addiction to the collapse of unstructured play, from the comparison culture taking over childhood to the perfectionism spiraling through young minds, every chapter illuminates a part of the modern childhood puzzle. Youll learn how sleep is disrupted, why attention spans are shrinking, why girls and boys are being pulled into very different digital traps, and how constant connectivity has created a generation overwhelmed by pressure yet disconnected from real life. What sets this book apart is its blend of clarity, compassion, and practicality. It avoids blame and instead offers real insight into how persuasive design, digital overstimulation, and the relentless pull of devices shape behaviour in ways children cannot defend themselves against. It breaks down the invisible systems behind obsessive scrolling, algorithmic pressure, and the economic forces that reward keeping young users online for as long as possible. But this is not just a diagnosis of the problem. It is a blueprint for change. Readers will discover how families, schools, and communities can reclaim childhood, protect developing minds, and rebuild space for play, imagination, rest, and authentic connection. With four clear rules for a freer childhood and a hopeful roadmap for the future, this book empowers adults to take back control in a world that feels increasingly engineered for distraction. Whether you are a parent, teacher, caregiver, or a concerned citizen, Addicted: Big Tech and Little Minds offers essential insights into the digital childhood crisis and practical steps toward restoring balance. It is a timely, vital guide for anyone who wants to help children grow up healthier, more resilient, and more connected to the real world. If youre ready to understand what has happened to childhood and how to change its future, this book is your essential companion.

Deep learning is no longer the future its the engine powering the world around us. From machines that understand speech and text, to systems that recognize faces, generate art, predict outcomes, and automate decision-making, deep learning is the core of the modern intelligence revolution. Yet for many, the subject still feels complex, intimidating, and out of reach. Deep Learning Demystified: Techniques and Applications changes that. This book strips away the confusion and delivers deep learning in a way that is clear, engaging, structured, and actionable. Built for curious beginners, ambitious developers, data professionals, and future AI builders, this guide breaks down neural networks, algorithms, and architectures with practical clarity while never losing sight of real-world usability. Through logical progression and thoughtful explanation, youll learn how deep learning works at a fundamental level starting with perceptrons, neurons, loss functions, activation layers, and model learning dynamics. Youll explore major modern architectures including convolutional networks for image understanding, recurrent models for sequential learning, attention-driven transformers for advanced intelligence, and generative systems that create entirely new data from scratch. But this is more than theory. You will discover how models actually learn, how theyre trained efficiently, how to overcome common pitfalls like overfitting, and how techniques like regularization, transfer learning, and optimized training improve performance in measurable ways. Youll understand deep learning applications in computer vision, natural language processing, generative creation, prediction models, automation pipelines, and decision-based intelligence. The book also covers the realities of deploying models outside the lab, walking you through deployment considerations, scalability, performance challenges, and real-world constraints that every practitioner faces. Youll learn what it takes to move from experimentation to production, how to manage model behavior, and how decision systems interact with industries, users, and feedback loops. Most importantly, this book addresses the responsibility that comes with building intelligent systems. Ethical considerations are woven throughout highlighting bias, transparency, accountability, explainability, and the societal impact of AI-driven automation. Youll learn not only how to build powerful models, but how to build them thoughtfully, responsibly, and with long-term trust in mind. Whether your goal is to understand how machines learn, build smarter models, enter the world of AI engineering, or simply decode one of the most important technologies of our time, this book is your straight-to-the-point, future-ready roadmap. No intimidation. No gatekeeping. No unnecessary complexity. Just real understanding, real application, and real potential. The age of deep learning is here. Now it makes sense.
