This study tests the feasibility, effectiveness, and efficiency of respondent-driven sampling (RDS) as a Web-based sampling method. Web-based RDS (WebRDS) is found to be highly efficient and effective. The online nature of WebRDS allows referral chains to progress very quickly, such that studies with large samples can be expected to proceed up to 20 times faster than with traditional sampling methods. Additionally, the unhidden nature of the study population allows comparison of RDS estimators to institutional data. Results indicate that RDS estimates are reasonable but not precise. This is likely due to bias associated with the random recruitment assumption and small sample size of the study. Finally, this article presents methods for testing the validity of assumptions required by RDS estimation.read more

Using Social Networks to Sample Migrants and Study the Complexity of Contemporary Immigration: An Evaluation Study.
TL;DR: It is shown that it is possible to recruit a probability sample of a locally rare immigrant group using NSM and achieve high response rates, and the feasibility of the collection and benefits of new forms of network data that transcend kinship networks in existing surveys are demonstrated.

Emerging Academic and Social Spaces: Toward a Modern Understanding of International Student Integration in Australasia
TL;DR: This study presents a dual-path model of international student integration that illustrates two parallel processes to improved institutional commitment: the staff-academic system, where staff's genuine concern for student development improves students' perceived academic progress, and commitment, and the student social-network-site system.

TL;DR: In this paper, the authors conducted formative research to assess appropriateness and acceptability of Respondent-Driven Sampling (RDS) in recruiting tertiary student men who have sex with men (TSMSM) into a prospective HIV/STI bio-behavioral survey in Nairobi, Kenya.
Influence Maximization on Families of Graphs
TL;DR: Influence Maximization on Families of Graphs shows that the influence of a graph’s graph-like properties has an important effect on the size of the graph itself.

Collective dynamics of small-world networks
TL;DR: Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

Respondent-driven sampling : A new approach to the study of hidden populations
TL;DR: A new variant of chain-referral sampling, respondent-driven sampling, is introduced that employs a dual system of structured incentives to overcome some of the deficiencies of such samples and discusses how respondent- driven sampling can improve both network sampling and ethnographic investigation.

Snowball Sampling—I
TL;DR: In this paper, the authors present two different approaches to snowball sampling: the first is to ask a person to inform potential subjects about the research project and share the investigator's contact information, and then it is up to the potential subjects to contact the investigator.
