Broadband Satellite Communication Systems and the Challenges of Mobility is an essential reference for both academic and professional researchers in the field of telecommunications, computer networking and wireless networks.

Recently the request of multimedia services has been rapidly increasing and satellite networks appear to be attractive for a fast service deployment and for extending the typical service area of terrestrial systems. In comparison with traditional wide area networks, a characteristic of satellite communication systems is their ability in broadcasting and multicasting multimedia information flows anywhere over the satellite coverage. The papers presented in this volume highlight key areas such as Satellite Network Architectures, Services and Applications; Mobile Satellite Systems and Services; and Hybrid Satellite and Terrestrial Networks.

Mobility will inevitably be one of the main characteristics of future networks, terminals and applications and, thus, extending and integrating fixed network protocols and services to mobile systems represents one of the main issues of present networking. The secondary focus of this volume is on challenges of mobility, that is, on technologies, protocols and services for the support of seamless and nomadic user access to new classes of applications in person-to-person, device-to-device and device-to-person environments. The book comprises recent results of research and development in the following areas; Seamless mobility; Mobile ad hoc and sensor networks; Analysis, simulation and measurements of mobile and wireless systems; Integration and inter-working of wired and wireless networks; QoS in mobile and wireless networks; Future trends and issues concerning mobility.

This state -of-the-art volume contains a collection of papers from two of the workshops of the 18th IFIP World Computer Congress, held August 22-27, 2004, in Toulouse, France: the Workshop on Broadband Satellite Communication Systems, and the Workshop on the Challenges of Mobility.

This book summarizes the results of an international research project; the first Europe-wide Delphi study on future developments in the energy sector (EurEnDel). Nearly 700 energy experts from 48 countries participated in this two-round, web-based Delphi exercise. With a time horizon of 2030, this expert survey not only provides a useful perspective on long-term developments of energy technologies, but also evaluates these technologies against different sets of social values or "visions."

Today the capability to create and apply new knowledge represents one of the main sources of sustained competitive advantage. Nevertheless, there are very few empirical studies of this. This book develops an improved and extended theoretical model about knowledge creation and transfer within organizations and tests it empirically with a survey in 115 knowledge-intensive firms. The results show the different knowledge creation processes employed by firms in practice and allow us to obtain evidence-driven models of the various foms of knowledge creation process.

"Focussing on innovation management, this book explores the role of knowledge stocks or intellectual capital blocks (human, social, technological, organizational and regional capitals) on the technological innovation processes typologies (process/product, radical/incremental) and firm performance, absorptive capabilities and organizational learning"--

This open access volume identifies the common and specific aspects of social mechanisms that generate inequalities, through comparative analyses of different dimensions in which inequalities are expressed. It includes studies on social inequalities in 5 European and 5 Latin American countries, along 11 thematic axes: inequalities in the labour market and labour trajectories; asymmetries in the relationship between training and employment; inequalities in work and family life; educational inequalities; geographical and social inequalities: ethnicity and language; social inequalities, migration and space; uncertainty, strategies, resources and capabilities; inequality of opportunity: intergenerational social mobility; social policies; gender inequalities; and research methodology. This volume is the result of a large collaborative project on social inequality funded by the European Commission: the International Network for Comparative Analysis of Social Inequalities. Taking into account diverse perspectives and approximations, the collaborators have created a general analytical framework as a model of analysis of social inequalities. The various contributions in this volume help readers gain a global outlook and help reflect on social inequalities in a comparative perspective. This volume addresses social science graduate and postgraduate students, researchers, social policy makers, as well as a broader academic audience interested in social inequality.

"There was no one in this country as ferocious, as brilliant, or as necessary as Pedro Pietri. In these days of growing inequality it is to his rebel vision I turn to for hope and for strength. A towering poet, absolutely peerless, explosively talented, a pioneer, and iconoclast, and activist, to whom the entire spoken word movement owes a debt beyond calculation."--Junot Diaz "One of the great American poets of the twentieth century, a leader of the Nuyorican poetry movement that ignited at Miguel Algarin's Nuyorican Poet's Cafe. Perhaps the most progressive and at the same time funniest poet of the period."--Amiri Baraka Pedro Pietri's often playfully absurd poems chronicle the joys and struggles of Nuyoricans--urban Puerto Ricans whose lives straddle the islands of Puerto Rico and Manhattan--and define the Latino experience in urban America. By turns angry, heartbreaking, and hopeful, his writings are imbued with a sense of pride and nationalism and were embraced by the generation of Latino poets that followed him. Pedro Pietri: Selected Poetry gathers the most enduring and treasured work among his published books, Puerto Rican Obituary, Traffic Violations, and Out of Order, along with a generous selection of his previously unpublished works. Pedro Pietri (1944--2004) was born in Ponce, Puerto Rico, and raised in Manhattan. In the early '70s he was a featured poet at the Nuyorican Poets Cafe. Juan Flores (1943-2014) was a professor and director of Latino Studies at New York University, and author of many books on Puerto Rican and Latino culture. Pedro Lopez Adorno is a professor in the Department of Africana and Puerto Rican/Latino Studies of Hunter College since 1987, and a published poet.
