The identification of reliable activation in these well-established reading-related regions (middle and superior temporal regions) is an important manipulation check, which is necessary for demonstrating the validity of the fixation-related fMRI approach for reading research.
It is equally important to test the reliability and validity of manual fixation of ankle positioning during SLR testing, as was the aim of Phase 2. Previous research has suggested that ankle dorsiflexion to 10° with the knee in full extension and during SLR testing is difficult to achieve and dorsiflexion may be limited to only 4.3-4.8° 4.3-4.8°6-4.8°) in thiSDsosition [ 6, 19].
Laboratory data on the canine model has proven the validity of this novel fixation technique.
However, issues like data quality can seriously influence the accuracy of the fixation detection methods and, thus, affect the validity of our results (Holmqvist, Nyström, & Mulvey, 2012).
Even the most accurate algorithms may generate a number of artifactual fixations that can corrupt the validity of the experimental results.
Poor eye-tracking recording can affect the validity of results, and sadly, it is still not common practice to report data quality measures or deeper descriptions of the fixation detection methods used (Holmqvist et al., 2011; 2012).
Specific parameters of interest were the fixation count (number of fixations inside the AOI), first fixation duration (duration of the first fixation to hit the AOI) and total fixation time (sum of the fixation durations inside the AOI).
Thus, as the choice of the fixation method was not restricted by fixation requirements of additional staining, ethanol fixation was favoured over PFA/ethanol fixation.
The aim of this study was to examine the validity of the use of two-cannulated-screws osteosynthesis in order to minimize the secondary effects of open fixation, especially in patients in whom an open reduction is contraindicated.
He questioned the validity of the proceeding).
EMachines was challenging the validity of the other seven patents.
