Thus, the remote and rural context may have exacerbated the sense of liminality for some volunteers, in the same way that it does for rural health care professionals [ 46, 47], in that it can be difficult to exist both as a 'practitioner' and as a community member when providing a service that includes confidentiality [ 48, 44].
However, in some special and practical application scenarios [9], that is difficult to guarantee there always exists the permanent path between the source and destination.
Considering that Hif1α does not belong to the category of genes involved in FA metabolism, it is difficult to establish what relationship exists with FA.
If a negative word and a relationship word cooccur in a sentence, it is difficult to judge whether there exists a relationship in the sentences only based on relationship words, so negative words features were introduced to improve the situation.
Momentum is difficult to gauge, if it even exists — you know it when you see it, or at least you think you do — but this game did seem to shift.
Therefore, same results show that this does not mean that the scale needs to be adjusted in order to improve it, mainly because, conceptually, QL is multidetermined and subjective and it is difficult to avoid the variability that exists in each cultural context (Gordia et al., 2011; Vilar, 2015).
The power of the tests employed here is relatively low, i.e. positive selection is difficult to detect even if it exists at many sites [7].
It is difficult to ascertain why this disparity exists.
It is difficult to prove that such bias exists because the real PPINs are mostly unknown.
Another possible limitation of our study is that all the IND patients in this cohort were referred to or seen at the University of Washington and Harborview Medical Centers, which implies that referral bias cannot be ruled out, but the direction of such bias, if it exists, is difficult to predict in this situation.
