Although transformations in retailing are of tremendous current interest there is no single broad ranging account of the evolution of retailing formats A Business History of Retail fills this gap providing a chronological presentation of changes in retail businesses and shopping experiences from pre industrial times to the present Retailing is explored as both an economic and a cultural phenomenon tracing retail strategies and business operations as they are reconfigured by retailers adapting to changing conditions new technologies government policies and evolving markets Relationships between the makers sellers and buyers of goods are shaped and reshaped as retailers large and small respond to competition and pursue new opportunities Areas of continuity are identified even as businesses grow and strategies evolve After four centuries there are more retailers selling more merchandise in more ways to more customers The mass consumption of goods and services is central to American and Canadian history and understanding consumer society requires understanding retailing Combining original research with recent scholarship in business and social history cultural theory and readings in current retail business strategy this study provides a valuable resourc

Through a recent series of breakthroughs, deep learning has boosted the entire field of machine learning. Now, even programmers who know close to nothing about this technology can use simple, efficient tools to implement programs capable of learning from data. This bestselling book uses concrete examples, minimal theory, and production-ready Python frameworks (Scikit-Learn, Keras, and TensorFlow) to help you gain an intuitive understanding of the concepts and tools for building intelligent systems.With this updated third edition, author Aurelien Geron explores a range of techniques, starting with simple linear regression and progressing to deep neural networks. Numerous code examples and exercises throughout the book help you apply what you've learned. Programming experience is all you need to get started.Use Scikit-learn to track an example ML project end to endExplore several models, including support vector machines, decision trees, random forests, and ensemble methodsExploit unsupervised learning techniques such as dimensionality reduction, clustering, and anomaly detectionDive into neural net architectures, including convolutional nets, recurrent nets, generative adversarial networks, autoencoders, diffusion models, and transformersUse TensorFlow and Keras to build and train neural nets for computer vision, natural language processing, generative models, and deep reinforcement learning

Smart Cities Blockchain Based Systems Networks and Data examines the various components that make up a smart city It focuses on infrastructure processes and services and outlines approaches for services such as health transport energy and more With an underlying emphasis on blockchain networks the authors examine ways to provide the management of resources and activities by creating a more secure and trustless operating systems where resources are more effectively allocated and managed Features Novel approaches toward the provision of smart city services Detailed explanations of how a blockchain based smart city network operates Novel design and architecture for cutting edge technologies such as energy systems and vehicular devices interacting with blockchain across smart cities Monitoring of data flow and the movement of several data types across different components of a smart city Comprehensive analysis of issues affecting entities across a smart city and the effects of blockchain based solutions This book is a practical and detailed demonstration for researchers and industry professionals who would use blockchain technology for effective city management

Assessing and Managing Security Risk in IT Systems: A Structured Methodology builds upon the original McCumber Cube model to offer proven processes that do not change, even as technology evolves. This book enables you to assess the security attributes of any information system and implement vastly improved security environments. Part I delivers an overview of information systems security, providing historical perspectives and explaining how to determine the value of information. This section offers the basic underpinnings of information security and concludes with an overview of the risk management process. Part II describes the McCumber Cube, providing the original paper from 1991 and detailing ways to accurately map information flow in computer and telecom systems. It also explains how to apply the methodology to individual system components and subsystems. Part III serves as a resource for analysts and security practitioners who want access to more detailed information on technical vulnerabilities and risk assessment analytics. McCumber details how information extracted from this resource can be applied to his assessment processes.

This new and completely updated edition is a comprehensive, easy-to-read, "how-to" guide on user research methods. You'll learn about many distinct user research methods and also pre- and post-method considerations such as recruiting, facilitating activities or moderating, negotiating with product developments teams/customers, and getting your results incorporated into the product. For each method, you'll understand how to prepare for and conduct the activity, as well as analyze and present the data - all in a practical and hands-on way. Each method presented provides different information about the users and their requirements (e.g., functional requirements, information architecture). The techniques can be used together to form a complete picture of the users' needs or they can be used separately throughout the product development lifecycle to address specific product questions. These techniques have helped product teams understand the value of user experience research by providing insight into how users behave and what they need to be successful. You will find brand new case studies from leaders in industry and academia that demonstrate each method in action. This book has something to offer whether you are new to user experience or a seasoned UX professional. After reading this book, you'll be able to choose the right user research method for your research question and conduct a user research study. Then, you will be able to apply your findings to your own products. * Completely new and revised edition includes 30+% new content!* Discover the foundation you need to prepare for any user research activity and ensure that the results are incorporated into your products * Includes all new case studies for each method from leaders in industry and academia

Los algoritmos, como instrumento principal de la inteligencia artificial y para el manejo de big data, son una oportunidad y un riesgo. En los distintos capítulos se analizan sus principales usos juridicamente relevantes, en que consisten y cuales serian las bases necesarias para encauzarlos juridicamente, de forma que se aproveche la oportunidad y se limiten los riesgos. La obra tiene su base en los trabajos presentados a un congreso celebrado el 25 de octubre de 2019, aunque se han actualizado y elaborado intensamente con posterioridad.

A lo largo de sus 700 páginas, este libro realiza un análisis detallado de la Norma UNE-ISO/IEC 20000, explicando cómo implantar un sistema de gestión en toda organización que ofrezca servicios de tecnologia, ya sea interna o externamente. Esta guia auna los requisitos de la norma, la experiencia de Telefonica y las mejores practicas ITIL; una fusion de conocimientos que convierten a este libro en un tratado de valor unico para el sector. Mas de 300 figuras y numerosos esquemas facilitan la comprension de los 14 procesos identificados en la gestion del servicio y que la norma clasifica en seis grupos: creacion, provision, relaciones, resolucion, control y entrega. Profesionales de Telefonica junto con otros especialistas en la gestion del servicio han elaborado este practico manual de consulta dirigido a grandes empresas, pymes, responsables de los departamentos de TI, tecnicos, consultores o formadores.
