Blockchain é uma tecnologia que permite a criação de um registro digital compartilhado e seguro, onde as transações são registradas e confirmadas através de uma rede descentralizada. Em outras palavras, o blockchain é uma espécie de livro-razão digital, onde todas as transações são registradas de forma permanente e imutável. Essa tecnologia é baseada em um conceito chamado de "cadeia de blocos", onde cada bloco contém um conjunto de transações. O blockchain foi criado em 2008 para ser a base do Bitcoin, a primeira criptomoeda do mundo. No entanto, a tecnologia tem potencial para ser usada em uma ampla gama de aplicações, como contratos inteligentes, identidade digital e gestão de cadeia de suprimentos.

The world is configured in ways that seem systematically hospitable to life forms, especially the human race. Is this the outcome of divine planning or simply of the laws of physics? Ancient Greeks and Romans famously disagreed on whether the cosmos was the product of design or accident. In this book, David Sedley examines this question and illuminates new historical perspectives on the pantheon of thinkers who laid the foundations of Western philosophy and science. Versions of what we call the "creationist" option were widely favored by the major thinkers of classical antiquity, including Plato, whose ideas on the subject prepared the ground for Aristotle's celebrated teleology. But Aristotle aligned himself with the anti-creationist lobby, whose most militant members—the atomists—sought to show how a world just like ours would form inevitably by sheer accident, given only the infinity of space and matter. This stimulating study explores seven major thinkers and philosophical movements enmeshed in the debate: Anaxagoras, Empedocles, Socrates, Plato, the atomists, Aristotle, and the Stoics.
The healthcare sector has never been under as much pressure as it is today. This pressure has motivated organizations to reinvent themselves, forcing management and marketing to take a more active role. Due to this reinvention, organizations must incorporate a stronger culture of management and marketing orientation that allows companies to define their course, optimize their resources, communicate with their stakeholders more efficiently, and encourage customers to become more involved with the company. This need is particularly urgent in the healthcare sector, as its weight in the economy has grown recently and it must prepare for economic recovery. Management and Marketing for Improved Competitiveness and Performance in the Healthcare Sector provides knowledge and skills to apply management and marketing on strategic, tactical, and operational aspects with an emphasis on the healthcare industry. Various aspects of management and marketing, such as operations management, quality management, human resources, brand management, and digital marketing, are discussed. The book is ideal for management and marketing academics, their students (undergraduate/graduate programs), researchers, managers, advertisers, healthcare organizations, hospital boards, pharmaceutical representatives, and marketers who need to optimize the potential of management marketing applied in the healthcare industry.
Over the course of several decades, copyright protection has been expanded and extended through legislative changes occasioned by national and international developments. The content and technology industries affected by copyright and its exceptions, and in some cases balancing the two, have become increasingly important as sources of economic growth, relatively high-paying jobs, and exports. Since the expansion of digital technology in the mid-1990s, they have undergone a technological revolution that has disrupted long-established modes of creating, distributing, and using works ranging from literature and news to film and music to scientific publications and computer software. In the United States and internationally, these disruptive changes have given rise to a strident debate over copyright's proper scope and terms and means of its enforcement-a debate between those who believe the digital revolution is progressively undermining the copyright protection essential to encourage the funding, creation, and distribution of new works and those who believe that enhancements to copyright are inhibiting technological innovation and free expression. Copyright in the Digital Era: Building Evidence for Policy examines a range of questions regarding copyright policy by using a variety of methods, such as case studies, international and sectoral comparisons, and experiments and surveys. This report is especially critical in light of digital age developments that may, for example, change the incentive calculus for various actors in the copyright system, impact the costs of voluntary copyright transactions, pose new enforcement challenges, and change the optimal balance between copyright protection and exceptions.
Wall Street Journal Bestseller "The pick of 2014's management books." –Andrew Hill, Financial Times "One of the top business books of the year." –Harvey Schacter, The Globe and Mail Bestselling author, Robert Sutton and Stanford colleague, Huggy Rao tackle a challenge that determines every organization’s success: how to scale up farther, faster, and more effectively as an organization grows. Sutton and Rao have devoted much of the last decade to uncovering what it takes to build and uncover pockets of exemplary performance, to help spread them, and to keep recharging organizations with ever better work practices. Drawing on inside accounts and case studies and academic research from a wealth of industries-- including start-ups, pharmaceuticals, airlines, retail, financial services, high-tech, education, non-profits, government, and healthcare-- Sutton and Rao identify the key scaling challenges that confront every organization. They tackle the difficult trade-offs that organizations must make between whether to encourage individualized approaches tailored to local needs or to replicate the same practices and customs as an organization or program expands. They reveal how the best leaders and teams develop, spread, and instill the right mindsets in their people-- rather than ruining or watering down the very things that have fueled successful growth in the past. They unpack the principles that help to cascade excellence throughout an organization, as well as show how to eliminate destructive beliefs and behaviors that will hold them back. Scaling Up Excellence is the first major business book devoted to this universal and vexing challenge and it is destined to become the standard bearer in the field.
