TLDR
Web-based RDS (WebRDS) is found to be highly efficient and effective and methods for testing the validity of assumptions required by RDS estimation are presented.Abstract:
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

TL;DR: HAMs awareness needs to be improved by including course content in the current curriculum, provision of hospital-based continuous training programs about patient safety and care, and establishment of multi-disciplinary health care teams, including board-certified pharmacists and specialized nurses, for the effective execution of medication use process in Pakistani hospitals in the future.

Prevalence of use of novel psychoactive substances
Harry Sumnall,Amanda Atkinson +1 more
TL;DR: It is found that earlier findings suggesting that some NPS such as mephedrone and synthetic cannabinoids showed signs of dispersal into the general population have not been sustained and the majority of NPS use still appears to be limited to small groups of people who use drugs and are considered at higher-risk of drug related harm.

Respondent-driven sampling and an unusual epidemic
TL;DR: In this article, a peer-driven sampling (RDS) is used for sampling hard-to-reach and/or stigmatized communities, where sampled individuals pass on participation coupons to at most $c$ of their acquaintances in the community, who then pass on to their acquaintances if they choose to participate.

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.
