Although the study was designed as an investigation of the frequency of CHV infection in dogs, initial findings of uniformly negative results from a large number of respiratory, plasma, and autopsy samples prompted us to widen our sampling to other mammalian species.
To widen the sampling frame we used social media sites to publicise the survey, which is likely to have increased the number of respondents but made it difficult to estimate the response rate.
Data refer to a sample of 22 economies (20 with the highest GDP plus Argentina, in 29th place, and South Africa, in 30th place, to widen the sample of countries whose primary exports make up an important part of total exports).
To triangulate the data from the focus group and to widen the sample of participants, two semi-structured interviews were held in another part of the country.
1 As there are fewer infants and children certified compared with adults, it was decided to widen the sample to include all parents of infants and children certified in all parts of England.
In this study, we substantially widen the sample of DEF- and GLO-like genes, incorporating new sequences from four out of five orchid subfamilies: Vanilloideae, Cypripedioideae, Orchidoideae and Epidendroideae, as well as Hypoxis, a member of the Asparagales frequently employed as outgroup in phylogenetic analyses of the Orchidaceae.
Accordingly, we widened our sampling scales in this region and collected samples from four contiguous sites of 25-a, 25-b, 25-c, and 25-d with the maximum pairwise distances about 28 km (Fig. 1).
Thus, large populations or large neighborhood size has a detriment effect in widening the sampling space, which implies increasing the computational budget, and thus the required number of function evaluations to achieve convergence.
The integrative review methodology widens the sampling frame beyond the limits imposed by meta-analysis (which focuses on primary studies) or systematic reviews (which focus on a single question, and place highest value on randomized clinical trials) [ 30].
An advantage to widening the sampling frequency to 48 h intervals is the ability to implement a manual version of this method in a clinical setting that frees up weekend time and mitigates resource burden on operators and facilities.
