Vacant drivers spontaneously relocate to mitigate the supply-demand imbalance embedded in ride-hailing services. In this study, we aim at addressing two fundamental questions. (i) To what extent can drivers' spontaneous relocation resolve the supply-demand imbalance? (ii) How does a ride-hailing platform design subsidy strategies to induce drivers' spontaneous relocation behaviors to cope with the platform-optimum goals? Specifically, we propose a leader-follower game theoretical framework to investigate the dynamic relocation game on a finite service network. The platform as the leader designs relocation subsidies to achieve service-oriented/interest-oriented goals, whereas idle drivers as followers then relocate to maximize individual utility, leading to a multistage driver equilibrium. We prove the existence of the equilibrium and utilize Mann Iteration with the shrunk relocation-destination-choice set to solve it efficiently. We derive the analytical conditions concerning the supply-demand profile and the platform commission rate, where the platform does not need to subsidize drivers but can simply rely on their spontaneous relocation to achieve the platform goals. For other cases where spontaneous relocation cannot achieve system optimum, we analytically prove that the gaps are bounded by constant discounts. Further, we depict the non-empty subsidy strategy for the platform to induce the relocation flow achieving system optimum. Thereafter, we extend the model to accommodate the sign-in/sign-off activities of drivers during the shift, their choice uncertainty, heterogeneous service forms, and elastic trip demands. A realistic data set is utilized to calibrate the models and derive managerial insights empirically.

Rock star, crowdfunding pioneer, and TED speaker Amanda Palmer knows all about asking. Performing as a living statue in a wedding dress, she wordlessly asked thousands of passersby for their dollars. When she became a singer, songwriter, and musician, she was not afraid to ask her audience to support her as she surfed the crowd (and slept on their couches while touring). And when she left her record label to strike out on her own, she asked her fans to support her in making an album, leading to the world's most successful music Kickstarter. Even while Amanda is both celebrated and attacked for her fearlessness in asking for help, she finds that there are important things she cannot ask for-as a musician, as a friend, and as a wife. She learns that she isn't alone in this, that so many people are afraid to ask for help, and it paralyzes their lives and relationships. In this groundbreaking book, she explores these barriers in her own life and in the lives of those around her, and discovers the emotional, philosophical, and practical aspects of The Art of Asking. Part manifesto, part revelation, this is the story of an artist struggling with the new rules of exchange in the twenty-first century, both on and off the Internet. The Art of Asking will inspire readers to rethink their own ideas about asking, giving, art, and love.

An exploration of how we see, use, and make sense of modern video game worlds. The move to 3D graphics represents a dramatic artistic and technical development in the history of video games that suggests an overall transformation of games as media. The experience of space has become a key element of how we understand games and how we play them. In Video Game Spaces, Michael Nitsche investigates what this shift means for video game design and analysis. Navigable 3D spaces allow us to crawl, jump, fly, or even teleport through fictional worlds that come to life in our imagination. We encounter these spaces through a combination of perception and interaction. Drawing on concepts from literary studies, architecture, and cinema, Nitsche argues that game spaces can evoke narratives because the player is interpreting them in order to engage with them. Consequently, Nitsche approaches game spaces not as pure visual spectacles but as meaningful virtual locations. His argument investigates what structures are at work in these locations, proceeds to an in-depth analysis of the audiovisual presentation of gameworlds, and ultimately explores how we use and comprehend their functionality. Nitsche introduces five analytical layers—rule-based space, mediated space, fictional space, play space, and social space—and uses them in the analyses of games that range from early classics to recent titles. He revisits current topics in game research, including narrative, rules, and play, from this new perspective. Video Game Spaces provides a range of necessary arguments and tools for media scholars, designers, and game researchers with an interest in 3D game worlds and the new challenges they pose.

You’re only a startup CEO once. Do it well with Startup CEO, a "master class in building a business." —Dick Costolo, Former CEO, Twitter Being a startup CEO is a job like no other: it’s difficult, risky, stressful, lonely, and often learned through trial and error.

A compassionate, shame-free guide for your darkest days “A one-of-a-kind book . . . to read for yourself or give to a struggling friend or loved one without the fear that depression and suicidal thoughts will be minimized, medicalized or over-spiritualized.”—Kay Warren, cofounder of Saddleback Church What happens when loving Jesus doesn’t cure you of depression, anxiety, or suicidal thoughts? You might be crushed by shame over your mental illness, only to be told by well-meaning Christians to “choose joy” and “pray more.” So you beg God to take away the pain, but nothing eases the ache inside. As darkness lingers and color drains from your world, you’re left wondering if God has abandoned you. You just want a way out. But there’s hope. In I Love Jesus, But I Want to Die, Sarah J. Robinson offers a healthy, practical, and shame-free guide for Christians struggling with mental illness. With unflinching honesty, Sarah shares her story of battling depression and fighting to stay alive despite toxic theology that made her afraid to seek help outside the church. Pairing her own story with scriptural insights, mental health research, and simple practices, Sarah helps you reconnect with the God who is present in our deepest anguish and discover that you are worth everything it takes to get better. Beautifully written and full of hard-won wisdom, I Love Jesus, But I Want to Die offers a path toward a rich, hope-filled life in Christ, even when healing doesn’t look like what you expect.

This book is the first technical overview of autonomous vehicles written for a general computing and engineering audience. The authors share their practical experiences of creating autonomous vehicle systems. These systems are complex, consisting of three major subsystems: (1) algorithms for localization, perception, and planning and control; (2) client systems, such as the robotics operating system and hardware platform; and (3) the cloud platform, which includes data storage, simulation, high-definition (HD) mapping, and deep learning model training. The algorithm subsystem extracts meaningful information from sensor raw data to understand its environment and make decisions about its actions. The client subsystem integrates these algorithms to meet real-time and reliability requirements. The cloud platform provides offline computing and storage capabilities for autonomous vehicles. Using the cloud platform, we are able to test new algorithms and update the HD map—plus, train better recognition, tracking, and decision models. This book consists of nine chapters. Chapter 1 provides an overview of autonomous vehicle systems; Chapter 2 focuses on localization technologies; Chapter 3 discusses traditional techniques used for perception; Chapter 4 discusses deep learning based techniques for perception; Chapter 5 introduces the planning and control sub-system, especially prediction and routing technologies; Chapter 6 focuses on motion planning and feedback control of the planning and control subsystem; Chapter 7 introduces reinforcement learning-based planning and control; Chapter 8 delves into the details of client systems design; and Chapter 9 provides the details of cloud platforms for autonomous driving. This book should be useful to students, researchers, and practitioners alike. Whether you are an undergraduate or a graduate student interested in autonomous driving, you will find herein a comprehensive overview of the whole autonomous vehicle technology stack. If you are an autonomous driving practitioner, the many practical techniques introduced in this book will be of interest to you. Researchers will also find plenty of references for an effective, deeper exploration of the various technologies.
