Strategies in E-Business
by Ignacio Gil-Pechuán Daniel Palacios-Marqués Marta Peris Peris-Ortiz Eduardo Vendrell Cesar Ferri-RamirezIn this volume, the authors apply insights from a variety of perspectives to explore the alignment among strategy, organization design, process and human resource management, and e-business practices on developing successful social networking programs--with particular regard to applying such initiatives against the backdrop of the global financial crisis and challenges to traditional business models. Showcasing in-depth case studies, the authors present emerging approaches to analyze the impact of investment in social networking sites, aligning internal resources, and measuring effects on positioning, branding, and new business creation. The fact that a growing proportion of the world population has a relationship with social networking sites could prove very valuable for companies. The question is whether this represents a business opportunity, whether companies know how to make the most of it and if they will make the necessary efforts to adapt to these new platforms. In the modern world, social networking sites have enormous potential for large as well as small and medium-sized enterprises (SMEs); most companies are aware of the need for a presence on social networking sites, but at present their e-business strategies are part of their medium and long-term strategic planning and only a small percentage have been put into practice. In short, this book attempts to answer the following questions: Is there a business opportunity for companies on social networking sites? Do they know how to make the most of it? Are they willing to make the necessary effort to adapt? Can e-business strategies contribute to company creation and the success of already existing businesses? And if so, how?

Strategische Onlinekommunikation
by Olaf Hoffjann Thomas PleilOnlinekommunikation und speziel Social Media sind als besonders wichtige Herausforderungen des Kommunikationsmanagements erkannt. Kaum ein Unternehmen verzichtet mittlerweile auf die Beobachtung von Diskussionen im Internet und die Umsetzung eigener Kommunikationsstrategien im Social Web. Dort verändern sich für die PR und die Organisationskommunikation zentrale Aspekte: Öffentlichkeiten können heute sehr viel schneller entstehen. Es sind neue Formen der Meinungsbildung zu beobachten, die zunehmend weniger den Mechanismen der Massenkommunikation folgen, sondern Ergebnis netzwerkartiger Prozesse sind. In diesem Umfeld entstehen gleichzeitig neue Formen der Beteiligung, die durch entsprechende niederschwellige Instrumente im Internet erst ermöglicht werden. Aus Organisationssicht verändern sich damit unter anderem Entstehung und Pflege von Reputation oder das Management von Stakeholderbeziehungen. Zehn Jahre nach Beginn der Fachdiskussion zu PR und sozialen Medien gibt dieser Band auf Basis aktueller Untersuchungen Einblick in die Praxis und in aktuelle Herausforderungen der Organisationskommunikation im Internet.

Strategy Analytics for Business Resilience Theories and Practices (Information Systems Engineering and Management #33)
by Sandeep Kautish Álvaro Rocha Ankur Gupta Sahil SawhneyA strategy is a blueprint of actions taken by managers to achieve the organization’s mission and vision and other long-term goals. In long term, strategy determines the success of an organization. While evaluating strategy, a company is essentially asking itself, “Where we are heading to and how we will achieve our goals?” Strategy Analytics is a relatively new field in conjunction with Strategic Management and Business Intelligence. Generally, Strategic Management field deals with the enhancement of the decision-making capabilities of managers. Typically, such decision-making processes are heavily dependent upon various internal and external reports. Managers need to develop their strategies using clear strategy processes supported by the increasing availability of data. This situation calls for a different approach to strategy, such as integration with analytics, as the science of extracting value from data and structuring complex problems. The term Strategic Analytics implies decisions are made, resources are invested, and plans for data and analytics are created based on the needs and critical questions a business is facing. The need for analytical solutions in today’s business environment is crucial because they allow users to think strategically about how an organization builds its core competencies and creates value. This not only informs the entire process, saves a lot of time, effort, and money, but also leads to value creation. This book will be one reference source to academic fraternity, management practitioners, business analysts and research students who are interesting in Strategic Analytics domain and using it in their research/practice work. In addition, the proposed book will be serving as state-of-art documentation of Strategy Analytics, its present role around organizational outcomes and outlines the need for greater integration in organization strategy and analytics for better strategic decision processes to measure corporate performance and business value creation. Distinguished Features of the proposed book State-of-art documentation of Strategy Analytics for Business Resilience and their applications for all levels of managerial positions. Excellent reference material for academic scientists, researcher and research scholars working in modern Strategy Analytics and Information Systems. This book will showcase the recent innovations, trends, and concerns as well as applied challenges encountered, and solutions adopted in the fields of Strategy Analytics

Strategy For An Army Center For Network Science, Technology, And Experimentation
by National Research Council of the National AcademiesThe U.S. military has committed to a strategy of network-centric warfare. As a result, the Army has become increasingly interested in the critical role of network science. To a significant extent, this interest was stimulated by an earlier NRC report, Network Science. To build on that book, the Army asked the NRC to conduct a study to define advanced operating models and architectures for future Army laboratories and centers focused on network science, technologies, and experimentation (NSTE). The challenges resulting from base realignment and closure (BRAC) relocations of Army research, development, and engineering resources--as they affected the NSTE program--were also to be a focus of the study. This book provides a discussion of what NSTE is needed by the Army; an examination of the NSTE currently carried out by the Army; an assessment of needed infrastructure resources for Army NSTE; and an analysis of goals, models, and alternatives for an NSTE center.

Strategy Rules
by Michael A. Cusumano David B. YoffieBetween 1968 and 1976, Bill Gates, Andy Grove, and Steve Jobs launched three companies that would define the world of high technology, create more than a trillion dollars in value, and transform our lives. How did they realize these incredible achievements? Strategy Rules examines these three individuals collectively for the first time--their successes and failures, comonalities and differences--revealing the business strategies and practices they pioneered while building their firms.Eminent business professors David Yoffie and Michael Cusumano have studied these three leaders and their companies for nearly thirty years, while teaching business strategy, innovation, and entrepreneurship at Harvard Business School and the MIT Sloan School of Management. In this enlightening guide, they show how Gates, Grove, and Jobs became masters of strategy. As CEOs, each approached strategy and execution in remarkably similar ways--yet markedly differently from their erstwhile competitors--keeping their focus on five rules: Look Forward, Reason Back: They determined where they want their companies to be in the future and could "reason back" to identify the moves that would take them there. Make Big Bets, Without Betting the Company: All three men made enormous strategic bets but rarely took gambles that put the financial viability of their companies at undue risk. Build Platforms and Ecosystems: Technology leaders have to create industry platforms that enable other firms to create complementary products and services that make the platforms increasingly valuable. Exploit Leverage and Power: Gates, Grove, and Jobs often turned opponents' strengths into weaknesses and used enormous resources (once they had them) to dominate competitors. Shape the Company around Your Personal Anchor: From Gates' understanding of software to Grove's devotion to process discipline and Jobs' obsession with design, all three built their companies around their personal strengths while compensating for their weaknesses.Strategy Rules brings together the best practices in strategic management and high-tech entrepreneurship, providing unique insights for start-up executives as well as the heads of modern multinationals.

Stream Big: The Triumphs and Turmoils of Twitch and the Stars Behind the Screen
by Nathan GraysonTold through the diverse and fascinating careers of nine streamers, this is the definitive story of Twitch and how the livestream platform revolutionized technology, entertainment, business, and pop culture. With 2.5 million viewers at any given moment, the streaming platform Twitch is in the lead and often well beyond mainstream networks like CNN and Fox during primetime. On Twitch, the Amazon-owned tech behemoth, the biggest personalities, like Kai Cenat, Félix &“xQc&” Lengyel, and Hasan &“HasanAbi&” Piker, can earn millions per year by firing up their internet connection and going live. Veteran technology and gaming journalist Nathan Grayson takes us inside the triumphs and tribulations of Twitch with exclusive access to its biggest content creators who helped make the platform into a billion-dollar global business. From Twitch&’s early days of rapid growth to acquisition by Amazon to the defection of creators and rival platforms, Grayson makes the radical argument that many social technology companies are far more dependent on their creators than the creators are on their platforms. Rivetingly told through nine exceptional Twitch creators whose on-screen personalities helped the company grow into a powerhouse, this is the explosive story of when entertainment meets the internet in the era of social and video content domination.
Stream Ciphers
by Andreas KleinIn cryptography, ciphers is the technical term for encryption and decryption algorithms. They are an important sub-family that features high speed and easy implementation and are an essential part of wireless internet and mobile phones. Unlike block ciphers, stream ciphers work on single bits or single words and need to maintain an internal state to change the cipher at each step. Typically stream ciphers can reach higher speeds than block ciphers but they can be more vulnerable to attack. Here, mathematics comes into play. Number theory, algebra and statistics are the key to a better understanding of stream ciphers and essential for an informed decision on their safety. Since the theory is less developed, stream ciphers are often skipped in books on cryptography. This book fills this gap. It covers the mathematics of stream ciphers and its history, and also discusses many modern examples and their robustness against attacks. Part I covers linear feedback shift registers, non-linear combinations of LFSRs, algebraic attacks and irregular clocked shift registers. Part II studies some special ciphers including the security of mobile phones, RC4 and related ciphers, the eStream project and the blum-blum-shub generator and related ciphers. Stream Ciphers requires basic knowledge of algebra and linear algebra, combinatorics and probability theory and programming. Appendices in Part III help the reader with the more complicated subjects and provides the mathematical background needed. It covers, for example, complexity, number theory, finite fields, statistics, combinatorics. Stream Ciphers concludes with exercises and solutions and is directed towards advanced undergraduate and graduate students in mathematics and computer science.
