Maximizing respondent-driven sampling field procedures in
The use of more than three coupons has been discouraged by researchers conducting HIV surveillance studies and those targeting intravenous drug users because they were concerned that the distribution of too many coupons to each participant would result in the oversaturation of certain networks too quickly, thus reducing the number of waves
Bathhouse distribution of HIV self-testing kits reaches
Men were systematically selected to receive a coupon, which could be redeemed that night for an HIV self-testing kit. Those offered the coupon were asked to take an 11-item survey. About 181 men received coupons, of whom 92 (51%) accepted the coupon, and 61 (66%) men redeemed the coupon.
Iron-Corroding Methanogen Isolated from a Crude-Oil
The surfaces of the coupons in the strain KA1 culture were quite different in appearance, with plate-shaped crystals that flaked off the coupons. The cross sections of the KA1 coupons showed that the surfaces had corroded to a much greater extent than did those of the other coupons.
Impact of environmental conditions on the survival of
Parallel experiments were conducted using clean and soiled coupons incubated under three temperatures. The die-off coefficient rates (K) were calculated using first-order exponential formula. For both parasites, the fastest die-off was recorded on fabric, followed by ceramic, formica, skin, and steel.
Evaluation of Compliance to National Nutrition Policies in
SDCs could seek partnerships with community entities, such as local grocery stores and nutrition experts, to help provide discounts/incentives (e.g., coupons) for healthy food and beverage purchases. Additionally, staff need to be made aware of current standards and be provided with opportunities to learn nutrition promotion skills and tips on

Electronic coupons are then printed from a personal computer or downloaded to a mobile device and brought to the study office to redeem for participation. Subsequent unpublished data showed a high correlation between participants who opted for electronic recruitment coupons and the use of mobile hookup apps.
Respondent-driven sampling to assess mental health
Participant recruitment. Study participants were recruited using respondent-driven sampling (RDS)—a peer-to-peer recruitment system used to sample hard-to-reach populations. 20 21 The details of RDS methodology for this study were previously described. 22 There were two study groups: (1) women raising children from SVRPs (parenting group) and (2) women who terminated SVRPs (termination group).
Quality improvement in emergency obstetric referrals
Background. In Ghana, maternal mortality stands at about 350 deaths/100 000 live-births, reaching higher rates in rural areas. 1 Skilled-birth attendance during deliveries is critical to reduce maternal mortality; however, ensuring that women deliver at facilities with qualified attendants has been a challenge in Ghana. Between 1993 and 2003, while institutional deliveries increased from 85%
