TL;DR: The music industry and the architectural innovations of online services for sharing music files on the business model of the music industry are analyzed and the design of media for the creation of economic value and the social and economic impact of peer-to-peer architectures are generalized.
Abstract: Peer-to-peer architectures gained much attention through their main application domain file sharing. First, we analyze the music industry and the architectural innovations of online services for sharing music files on the business model of the music industry. In the second main part of the paper, we generalize our observations to the design of media for the creation of economic value and the social and economic impact of peer-to-peer architectures. We analyze here virtual communities and other peer-to-peer architectures.

TL;DR: The possible impact of success factors that are identified to the design and implementation of e-services as part of the business model for virtual communities of patients and the expectations of consumers of health related content on the Internet are analyzed.
Abstract: This paper presents results of an empirical study regarding success factors of virtual communities of patients. These success factors capture what is important to members of virtual communities of patients and the interconnections between these aspects. We analyze the possible impact of success factors that we identify to the design and implementation of e-services as part of the business model for virtual communities of patients. We analyze what is of major interest to members of virtual communities of patients and the expectations of consumers of health related content on the Internet. This paper focuses on virtual communities of patients. Recommendations for new e-services are being discussed.

TL;DR: This paper emphasizes that these search times can be significantly influenced by the message forward algorithm and by the topology of the community, which can be easily changed by respective, local executed algorithms.
Abstract: P2P-networks become more and more interesting not only because of the emergence of file sharing systems like Gnutella. Such decentralized systems have a lot of advantages compared to centralized client-server systems. However, information search is still a central problem in such P2P web communities, since the used complete search with message chains may cause high search response times. In this paper we emphasize that these search times can be significantly influenced by the message forward algorithm and by the topology of the community, which can be easily changed by respective, local executed algorithms. For doing so, content and traffic oriented methods were proposed. Their efficiency has been proved through a simulation and the respective results.

TL;DR: In this article, the authors present an economic framework to study and develop different market-based mechanisms for resource allocation in an ad-hoc grid, where consumers and producers of resources are autonomous agents that cooperate through a simple, single metric namely the price that summarizes the global state of a network in a number.
Abstract: In this dissertation, we present an economic framework to study and develop different market-based mechanisms for resource allocation in an ad-hoc Grid. Such an economic framework helps to understand the impact of certain choices and explores what are the suitable mechanisms from Grid user/owner perspectives under given circumstances. We focus on resource allocation in a Grid-based environment in the case where some resources are lying idle and could be linked with overloaded nodes in a network. In such networks, the resources are neither necessarily dedicated nor have predictable availability at any point in time. We call such networks ad-hoc Grids. Self-interested nodes in ad-hoc Grids are considered as consumers (buyers) and producers (sellers) of resources within the economic framework. Consumers and producers of resources are autonomous agents that cooperate through a simple, single metric namely the price that summarizes the global state of a network in a number. The price represents all the available information that may reside at the level of the individual nodes and that is not necessarily shared among them. A middle agent, named the matchmaker, sets up a mutual agreement between consumer and producer agents based on the price by employing economic mechanisms such as auctions. The transaction is established when the consumer and producer constraints such as resource quantity, time, and budget are met. In this dissertation, we study market-based resource allocation mechanisms at macro and micro levels. Macroeconomics addresses the behavior of an economy at the aggregate level and microeconomics describes the individual behavior. At the macro level, we compare different economic models as the matchmaking mechanisms. We study the impact of choosing particular auction mechanisms in the framework. At the micro-level, we study different pricing mechanisms and investigate the effect of introducing money and budget constraints. Furthermore, we analyze different bidding strategies that help agents to better achieve their objectives under varying constraints.

TL;DR: This paper proposes the implementation of a prototype application that makes use of a structured P2P system enabling the indexing of complex metadata, used to express digital rights on DHT based networks.
Abstract: Peer-to-peer (P2P) systems are widely used for sharing digital items without structured metadata and in absence of any kind of digital rights management applied to the distributed contents. In this paper we propose the implementation of a prototype application that makes use of a structured P2P system enabling the indexing of complex metadata, used to express digital rights. In this way the media contents are exchanged and played according to the expressed grants. The creation and the consumption of the shared contents can be performed through any MPEG-21 REL compliant software and the application allows indexing and search for both governed and ungoverned contents. The information about the license can be included in the queries and the P2P network can be used to share governed contents (both free and with fee) in a legitimate way. In particular the proposed approach represents a suitable solution for indexing and querying rights complex structures on DHT based networks.

TL;DR: In The Unified Modeling Language User Guide, the original developers of the UML provide a tutorial to the core aspects of the language in a two-color format designed to facilitate learning.
Abstract: In The Unified Modeling Language User Guide, the original developers of the UML--Grady Booch, James Rumbaugh, and Ivar Jacobson--provide a tutorial to the core aspects of the language in a two-color format designed to facilitate learning. Starting with a conceptual model of the UML, the book progressively applies the UML to a series of increasingly complex modeling problems across a variety of application domains. This example-driven approach helps readers quickly understand and apply the UML. For more advanced developers, the book includes a learning track focused on applying the UML to advanced modeling problems.With The Unified Modeling Language User Guide, readers will:Understand what the UML is, what it is not, and why it is relevant to the development of software-intensive systemsMaster the vocabulary, rules, and idioms of the UML in order to "speak" the language effectivelyLearn how to apply the UML to a number of common modeling problemsSee illustrations of the UML's use interspersed with use cases for specific UML features, andGain insight into the UML from the original creators of the UML.

TL;DR: Information Rules will help business leaders and policy makers - from executives in the entertainment, publishing, hardware, and software industries to lawyers, finance professionals, and writers -- make intelligent decisions about their information assets.
Abstract: From the Publisher: Information Goods -- from movies and music to software code and stock quotes - have supplanted industrial goods as the key drivers of world markets. Confronted by this New Economy, many instinctively react by searching for a corresponding New Economics to guide their business decisions. Executives charged with rolling out cutting-edge software products or on-line versions of their magazines are tempted to abandon the classic lessons of economics, and rely instead on an ever changing roster of trends, buzzwords, and analogies that promise to guide strategy in the information age. Not so fast, say authors Carl Shapiro and Hal R. Varian. In Information Rules they warn managers, "Ignore basic economic principles at your own risk. Technology changes. Economic laws do not." Understanding these laws and their relevance to information goods is critical when fashioning today's successful competitive strategies. Information Rules introduces and explains the economic concepts needed to navigate the evolving network economy. Information Rules will help business leaders and policy makers - from executives in the entertainment, publishing, hardware, and software industries to lawyers, finance professionals, and writers -- make intelligent decisions about their information assets.

TL;DR: It is argued that free riding leads to degradation of the system performance and adds vulnerability to the system, and copyright issues might become moot compared to the possible collapse of such systems.
Abstract: An extensive analysis of user traffic on Gnutella shows a significant amount of free riding in the system. By sampling messages on the Gnutella network over a 24-hour period, we established that almost 70% of Gnutella users share no files, and nearly 50% of all responses are returned by the top 1% of sharing hosts. Furthermore, we found out that free riding is distributed evenly between domains, so that no one group contributes significantly more than others, and that peers that volunteer to share files are not necessarily those who have desirable ones. We argue that free riding leads to degradation of the system performance and adds vulnerability to the system. If this trend continues copyright issues might become moot compared to the possible collapse of such systems.
