- Abstract
- The Digital Object Identifier (DOI) has been developed by the academic technical and medical publishing sectors to enable the management of access rights to information published electronically. The DOI system has evolved from the physical documentary unit identifiers developed in the 1970, physical and document logical unit identifiers developed in the 1980s and recently modified to meet the needs of electronic distribution. This experience is integrated into the standardization, currently in progress on the Internet network, of the identification of resources and their localization. The DOI system is potentially the object of an international standard as the ISBN and the ISSN have been

- Abstract
- Interfaces of the next generation of nomadic network services will need to be widely varying, modality independent, flexible and straight forward and easy to learn. Gives examples of the types of systems needed and sets out strategies for achieving anyone / anytime and anywhere interfaces. These systems will address the equity issues of providing access to those with disabilities, those with lower technology and bandwidth devices and provide support for agent software

- Abstract
- Online communities are becoming an important tool in the communication and participation processes in our society. However, the most widespread applications are difficult to use for people with disabilities, or may involve some risks if no previous training has been undertaken. This work describes a novel social network for cognitively disabled people along with a clustering-based method for modeling activity and socialization processes of its users in a noninvasive way. This closed social network is specifically designed for people with cognitive disabilities, called Guremintza, that provides the network administrators (e.g., social workers) with two types of reports: summary statistics of the network usage and behavior patterns discovered by a data mining process. Experiments made in an initial stage of the network show that the discovered patterns are meaningful to the social workers and they find them useful in monitoring the progress of the users.

- Abstract
- Community networks have existed since the 1970s when Community Memory in Berkeley, Californis, installed terminals in public places for people to read and post material of all sorts on a centralised time sharing system. Community Memory was the first known community access network. Several foundations and government agencies have funded community networks, known as freenets. Discusses the freenet movement; library involvement; the Apple Library of Tomorrow and the Morino Foundation conference on community networks and how to keep in touch with community network developments

- Abstract
- Social networks evolve over time with the addition and removal of nodes and links to survive and thrive in their environments. Previous studies have shown that the link-formation process in such networks is influenced by a set of facilitators. However, there have been few empirical evaluations to determine the important facilitators. In a research partnership with law enforcement agencies, we used dynamic social-network analysis methods to examine several plausible facilitators of co-offending relationships in a large-scale narcotics network consisting of individuals and vehicles. Multivariate Cox regression and a two-proportion z-test on cyclic and focal closures of the network showed that mutual acquaintance and vehicle affiliations were significant facilitators for the network under study. We also found that homophily with respect to age, race, and gender were not good predictors of future link formation in these networks. Moreover, we examined the social causes and policy implications for the significance and insignificance of various facilitators including common jails on future co-offending. These findings provide important insights into the link-formation processes and the resilience of social networks. In addition, they can be used to aid in the prediction of future links. The methods described can also help in understanding the driving forces behind the formation and evolution of social networks facilitated by mobile and Web technologies.

- Abstract
- Teenagers are among the most prolific users of social network sites (SNS). Emerging studies find that youth spend a considerable portion of their daily life interacting through social media. Subsequently, questions and controversies emerge about the effects SNS have on adolescent development. This review outlines the theoretical frameworks researchers have used to understand adolescents and SNS. It brings together work from disparate fields that examine the relationship between SNS and social capital, privacy, youth safety, psychological well-being, and educational achievement. These research strands speak to high-profile concerns and controversies that surround youth participation in these online communities, and offer ripe areas for future research.
