We use the proficiency testing criteria to define acceptable analytical performance (CLIA 1992): ±4 mmol/l for sodium, ±0.5 mmol/l for potassium, ±5 % for chloride, ±0.6 g/l for glucose, ±6 % for hematocrit and ±7 % for hemoglobin.
19 The analysis has been validated as proficient using the World Health Organization HPV DNA genotyping proficiency panel.
Using the true person proficiency scores from Equation 10 and the known item parameters, the response probability for person n and item i was defined according to the item response model (see Equation 1): P X ni = 1 = e θ n − b i 1 + e θ n − b i. (11).
Two measurement instruments were used: the General English Proficiency Test (GEPT) and the questionnaire on learning motivation, test value, and test anxiety.
The trial found a nearly 20% reduction in practice time to reach proficiency using the CuSum curriculum but long-term effects of decreased practice volume on proficiency is unknown.
From this comparison, it can be seen that the results of our lab in the proficiency tests using the methods described in the present study are in line with the outcome of other labs analysing the same samples.
Overall, Luna wrote, "[t]he speed with which scientists can hope to achieve narrative proficiency using the tools in the book is one of its remarkable strengths and a testament to Olson's straightforward advice". .
procedures using the Koken Colonoscopy Training Model and reported proficiency regarding passage after two training procedures in humans (screenees).
Once students develop proficiency using the rubric, they then have opportunities to practice using it to evaluate their peers' writing; peer reviews are worth 20% of the course grade and are graded based on the justification they give for their assessment.
In summary, we inserted the araC-Cre gene expression cassette into the chromosomal lacZ gene of E. coli recA- strain HB101 by creating transient homologous recombination proficiency using the plasmid-born recET genes and employing homology-mediated chromosomal "pop-in, pop-out" of a Cre plasmid pBAD75Cre with a temperature sensitive replication origin.
