- 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
- In this research, we aim to identify factors that significantly affect the clickthrough of Web searchers. Our underlying goal is determine more efficient methods to optimize the clickthrough rate. We devise a clickthrough metric for measuring customer satisfaction of search engine results using the number of links visited, number of queries a user submits, and rank of clicked links. We use a neural network to detect the significant influence of searching characteristics on future user clickthrough. Our results show that high occurrences of query reformulation, lengthy searching duration, longer query length, and the higher ranking of prior clicked links correlate positively with future clickthrough. We provide recommendations for leveraging these findings for improving the performance of search engine retrieval and result ranking, along with implications for search engine marketing.

- Abstract
- Examines the use of networked information sources in scholarly communication. Networked information sources are defined broadly to cover: documents and images stored on electronic network hosts; data files; newsgroups; listservs; online information services and electronic periodicals. Reports results of a survey to determine how heavily, if at all, networked information sources are cited in scholarly printed periodicals published in 1993 and 1994. 27 printed periodicals, representing a wide range of subjects and the most influential periodicals in their fields, were identified through the Science Citation Index and Social Science Citation Index Journal Citation Reports. 97 articles were selected for further review and references, footnotes and bibliographies were checked for references to networked information sources. Only 2 articles were found to contain such references. Concludes that, although networked information sources facilitate scholars' work to a great extent during the research process, scholars have yet to incorporate such sources in the bibliographies of their published articles

- 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
- This article has three goals. It begins by reviewing the current state of the Internet as a data transport system and some of its emerging problems. Then it discusses 2 major research initiatives - Internet 2 and the Next Generation Internet (NGI) program - and some of the new network-level services that may first see substantial deployment in these new research testbeds. The article concludes with a few speculations about future changes to the Internet as a data transport system

- 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.

- Abstract
- This study explores the main determinants of social network adoption at the country level. We use the technology-organization-environment (TOE) framework to investigate factors influencing social network adoption. The authors use cross-sectional data from 130 countries. The results indicate that social network adoption, at the country level, is positively influenced by the technological maturity, public readiness, and information and communication technology law sophistication. Technological, organizational, and environmental factors altogether accounted for 67% of variance in social network adoption. These findings provide a first insight into the usage of social network sites at the country level, as well as the main factors that influence public adoption. Implications for research and practice are discussed.

- Abstract
- Structural cohesion, hierarchy, holes, and percolating clusters share a complementary existence in many social networks. Although the individual influences of these attributes on the structure and function of a network have been analyzed in detail, a more accurate picture emerges in proper perspective and context only when research methods are employed to integrate their collective impacts on the network. In a major research project, we have undertaken this examination. This paper presents an extract from this project, using a global network assessment of these characteristics. We apply our methods to analyze the collaboration networks of a subset of researchers in India through their coauthored papers in peer-reviewed journals and conference proceedings in management science, including related areas of information technology and economics. We find the Indian networks to be currently suffering from a high degree of fragmentation, which severely restricts researchers' long-rage connectivities in the networks. Comparisons are made with networks of a similar sample of researchers working in the United States.

- Abstract
- Basic human values represent what we think are important to our lives that include security, independence, success, kindness, and pleasure. Each of us holds different values with different degrees of importance. Existing studies show that values of a person can be identified from their social network usage. However, the value priority of a person may change over time due to different factors such as time, event, influence, social structure, and technology. In this research, we are the first to investigate whether the change of value priorities can be identified from social network usage. We propose a weighted hybrid time-series-based model to capture the change of values of a social network user. We conducted an experimental study with 726 Facebook users and showed that our model accurately captures the value priority changes from the social network usage and achieves significantly higher accuracy than our baseline hidden Markov model-based technique. We also validated the change of a user's value priorities in real life using a questionnaire-based technique.

- Abstract
- Reports results of a study that examined factors influencing the adoption and use of electronic networks by science and engineering faculty in 6 small universities in the southerneaster USA. Part of the study gathered data on the purpose, type, and extent of electronic communications. Data were gathered by mail questionnaire and by follow up site visits. Reports on 5 types of network use, electronic mail, electronic discussion groups, accessing remote databases, accessing remote computer facilities, and file transfer. For each service, data are reported for frequency of use by purpose: research, teaching administration, social and current awareness. Outlines preliminary use indicators for each service in terms of heavy and moderate use

- Abstract
- Academic social networking sites seek to bring the benefits of online networking to an academic audience. The ability to make connections to others is a defining characteristic of the sites, but what types of networks are formed, and what are the implications of the structures? This study addressed that question through mixed methods social network analysis, focusing on Academia.edu, ResearchGate, and Twitter, as three of the main sites used by academics in their professional lives. The structure of academics' ego-networks on social networking sites differs by platform. Networks on academic sites were smaller and more highly clustered, whereas Twitter networks were larger and more diffuse. Institutions and research interests define communities on academic sites, compared with research topics and personal interests on Twitter. The network structures reflect differences in how academics conceptualize different sites and have implications in relation to fostering social capital and research impact.

- Abstract
- I describe a set of automated archives for electronic communication of research information in many fields of physics, and some related and unrelated disciplines, starting from 1991. These archives now serve over 35.000 users worldwide from over 70 countries, and process more than 70.000 electronic transaction per day. In some fields of physics, they have already supplanted traditional research journals as conveyors of both topical and archival research information

- Enthält die Bemerkung: "The problems of indexing and categorization of information in principle lie within the purview of library and information science communities, but to date theirs has been a curiously low profile in the electronic realm, while various amateur brute-force indexing schemes are running dangerously amok. It would be remarkable if centuries of ostensibly relevant experience will find little applicability in the network context"

- Abstract
- Academic libraries have been on the leading edge in the provision of services, navigation aids, and user training for the Internet and the emerging National Research and Education Network (NREN). Yet empirical research and synthesis of librarians' experience with electronic networking is scarce. Reports selected findings from a recently completed study that examined the impact of the national networked environment on academic libraries. Its goals was to investigate the roles of academic libraries and librarians in the national networking context. Summarizes the study activities and key issues and findings from data analysis

- Abstract
- The proposal is to use clusters, graphs and networks as models in order to analyse the Web structure. Clusters, graphs and networks provide knowledge representation and organization. Clusters were generated by co-site analysis. The sample is a set of academic Web sites from the countries belonging to the European Union. These clusters are here revisited from the point of view of graph theory and social network analysis. This is a quantitative and structural analysis. In fact, the Internet is a computer network that connects people and organizations. Thus we may consider it to be a social network. The set of Web academic sites represents an empirical social network, and is viewed as a virtual community. The network structural properties are here analysed applying together cluster analysis, graph theory and social network analysis. This is a work having taken place in the EICSTES project. EICSTES means European Indicators, Cyberspace, and the Science-Technology-Economy System. It is a research project supported by the Fifth Framework Program of R&D of the European Commission (IST-1999-20350)
