Time-location sampling with capture-recapture to assess specialised recreational fisheries

Fisheries Research, 2014
Specialisation in recreational fisheries has led to increasing diversification and segmentation of fishers into small 'hard-to-reach' populations that are inherently difficult and costly to sample using traditional methods. In this paper, we quantitatively assess, and expand upon, time-location sampling (TLS) for a specialised recreational sport ...

Use of Time-location Sampling for Systematic Behavioral Surveillance of Truck Drivers in Brazil

AIDS and Behavior, 2008
We assessed HIV-related risk behavior in a time-location sampling (TLS) interviewer administered survey of male truck drivers at the crossroads of two of the major highways used for trucking in Northeast Brazil (N = 686). Overall, 21.3% had sex while on the road (2.8% unprotected); 12.3% had sex with commercial sex workers (1.4% unprotected); 1.8% had ...

Methodology: a Time-Location Sampling Survey Among Bulgarians in Hamburg

2021
This chapter introduces the time-location sampling survey carried out among Bulgarian migrants in Hamburg. First, I discuss the challenges in surveying the population of migration background (section 3.1) and the advantages of time-location sampling for studying the population of Bulgarian origin (section 3.2).

A Comparison Between Respondent-Driven Sampling and Time-Location Sampling Among Men Who Have Sex with Men in Shenzhen, China

Archives of Sexual Behavior, 2014
Men who have sex with men (MSM) are a key population for HIV control and prevention in China. It is difficult to acquire representative samples of this hidden population. Respondent-driven sampling (RDS), based on peer referral, and time-location sampling (TLS) based on random selection of venue-day-time periods, are among the most commonly used ...

Variation of Time-Averaged Indoor and Outdoor Radon Concentrations with Time, Location and Sampling Height

Radiation Protection Dosimetry, 1988
Abstract To study the long-term variations of indoor and outdoor radon concentrations time-averaged radon concentrations were measured in and around two dwellings over a period of almost five years. The integration times for passive dosemeters ranged from 4 to about 18 months.

An Empirical Comparison of Respondent-driven Sampling, Time Location Sampling, and Snowball Sampling for Behavioral Surveillance in Men Who Have Sex with Men, Fortaleza, Brazil

AIDS and Behavior, 2008
Obtaining samples of populations at risk for HIV challenges surveillance, prevention planning, and evaluation. Methods used include snowball sampling, time location sampling (TLS), and respondent-driven sampling (RDS). Few studies have made side-by-side comparisons to assess their relative advantages.

High HIV Prevalence among Men who have Sex with Men in a Time-Location Sampling Survey, São Paulo, Brazil

AIDS and Behavior, 2014
We conducted a time-location sampling sero-behavioral surveillance survey of men who have sex with men (MSM) in São Paulo, Brazil, the largest city in Latin America and the Southern Hemisphere (N = 1,217 interviewed with serological results for 771).
