This implies that if universal voluntary HIV testing is currently impossible or impractical, lowering risk behavior is the prominent control mechanism of HIV incidence even in the presence of effective treatment.
Or is this so impractical as to risk bringing the whole system into jeopardy?
Even if these 12 indicators were technically important for the management of local health systems, they are impractical because they risk inducing health workers to commit errors.
As this may seem impractical in a risk-management context, it is proposed to introduce "a-posteriori subjectivity" (as opposed to the "a-priori subjectivity" introduced by the arbitrary selection of single probability distributions) by defining a single indicator of evidence as a weighted average of Plausibility and Belief, with weights to be defined according to the specific context.
As manual analysis of large-scale online information is impractical, and interactive methods risk alerting the target, alternatives are desirable.
Earlier Graetzel designs, however, mostly relied on a liquid electrolyte to replenish the dye with electrons; this proved impractical because of the risk of leakage.
While randomized controlled trials are still considered the gold standard for evaluating medical outcomes, trials are both cost-prohibitive and impractical for evaluating the risk of long-term THA revision [2].
However, where substrate type comprises mixed or rocky habitats, sled mounted sensors are impractical because of the risk of entanglement, leading to equipment damage or loss, and because heavy sleds are themselves destructive, functioning in a similar manner to a light dredge or trawl.
This makes ICU admission for every at-risk patient impractical since stable patients will end up using scarce ICU resources.
Currently, positive endoscopic biopsy is the standard criterion for gastric cancer diagnosis, but is invasive and impractical for screening high-risk patients who may have multiple suspicious lesions [ 16].
Written consent was deemed impractical in this large low risk survey by the Department, verbal consent was obtained by the interviewers and audited by the Department, and the oral informed consent process was approved by the research ethics committee of the Department.
