Distant-Time Location Prediction in Low-Sampling-Rate Trajectories [PDF]
2013 IEEE 14th International Conference on Mobile Data Management, 2013 With the growth of location-based services and social services, low-sampling-rate trajectories from check-in data or photos with geo-tag information becomes ubiquitous. In general, most detailed moving information in low-sampling-rate trajectories are lost.

Sampling Males Who Inject Drugs in Haiphong, Vietnam: Comparison of Time-Location and Respondent-Driven Sampling Methods [PDF]
Journal of Urban Health, 2015 Accurate measurements of HIV prevalence and associated risk factors among hidden and high-risk groups are vital for program planning and implementation. However, only two sampling methods are purported to provide representative estimates for populations without sampling frames: time-location sampling (TLS) and respondent-driven sampling (RDS).

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 ...

International Journal of Drug Policy, 2020
In the last decade, European cities saw the development of "slamming," a practice related to chemsex that combines three elements: a sexual context, psychostimulant drug use, and injection practices. Epidemiological data on this practice is still sparse and media attention might have unintentionally distorted the size of this phenomenon.

Use of Time-location Sampling for Systematic Behavioral Surveillance of Truck Drivers in Brazil
AIDS and Behavior, 2008We 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 ...

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.

Time-location sampling with capture-recapture to assess specialised recreational fisheries
Fisheries Research, 2014Specialisation 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 ...

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.

Methodology: a Time-Location Sampling Survey Among Bulgarians in Hamburg
2021This 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).
