Parent-implemented intervention for children in third to fifth grade with dyslexia.

BACKGROUND: Few studies have investigated the acceptability and efficacy of intensive parent-implemented interventions for children with dyslexia. METHODS: We carried out a randomized controlled trial on 22 dyslexic children from 3rd to 5th grade. Reading performance was measured before (T1) and after (T2) summer by a selection of tests from the BALE and EDA batteries. One group received a specific parent-implemented repeated reading training (RR group) and the other group received a general training based on a summer vacation workbook (SVW group), adapted for children with reading impairment. The training lasted 6 weeks during the summer vacation. RESULTS: In both groups, the reading performances of the dyslexic children were stable before and after the summer. No group difference was found on our primary outcome corresponding to an aggregate score of the z-scores of the BALE reading lists of regular, irregular and pseudo-words. However, secondary analyses revealed that the score of the EDA subtest "number of words read in one minute" (tapping reading fluency) differed significantly between the two groups (T2-T1=0.17 SD for the RR group and T2-T1=-0.24 SD for the SVW group; P=0.015). Acceptability was generally good (dropout rate of 9% in the RR group). CONCLUSIONS: A repeated reading intervention applied by parents may improve reading fluency of dyslexic children during summer vacation, with a good acceptability. Further studies are needed to confirm these findings.

SEIS: Insight's Seismic Experiment for Internal Structure of Mars.

By the end of 2018, 42 years after the landing of the two Viking seismometers on Mars, InSight will deploy onto Mars' surface the SEIS (Seismic Experiment for Internal Structure) instrument; a six-axes seismometer equipped with both a long-period three-axes Very Broad Band (VBB) instrument and a three-axes short-period (SP) instrument. These six sensors will cover a broad range of the seismic bandwidth, from 0.01 Hz to 50 Hz, with possible extension to longer periods. Data will be transmitted in the form of three continuous VBB components at 2 sample per second (sps), an estimation of the short period energy content from the SP at 1 sps and a continuous compound VBB/SP vertical axis at 10 sps. The continuous streams will be augmented by requested event data with sample rates from 20 to 100 sps. SEIS will improve upon the existing resolution of Viking's Mars seismic monitoring by a factor of ∼ 2500 at 1 Hz and ∼ 200 000 at 0.1 Hz. An additional major improvement is that, contrary to Viking, the seismometers will be deployed via a robotic arm directly onto Mars' surface and will be protected against temperature and wind by highly efficient thermal and wind shielding. Based on existing knowledge of Mars, it is reasonable to infer a moment magnitude detection threshold of M w ∼ 3 at 40 ∘ epicentral distance and a potential to detect several tens of quakes and about five impacts per year. In this paper, we first describe the science goals of the experiment and the rationale used to define its requirements. We then provide a detailed description of the hardware, from the sensors to the deployment system and associated performance, including transfer functions of the seismic sensors and temperature sensors. We conclude by describing the experiment ground segment, including data processing services, outreach and education networks and provide a description of the format to be used for future data distribution.
