S7E1: What is the state of Kâ12 education?
The average school day today looks different than in years past. Kâ12 educators face a myriad of challenges this year, including teacher and other staffing shortages, distance learning, the politicization of curricula, calls for book bans and the fallout from the COVID-19 pandemic.
In the first episode of Season 7 of âThe Maine Question,â we speak with Penny Bishop, dean of the University of Maine College of Education and Human Development; Jim Artesani, associate dean of graduate studies, research and outreach for the college; and Courtney Angelosante, coordinate of the Positive Behavior Supports & Interventions (PBIS) Initiative, to discuss the latest issues in the field of education, as well as opportunities for new and improved learning
Student Pilot Perceptions of Flight Training
Within the aviation industry, there is an increasing demand for an estimated 635,000 new pilots over the next 20 years (Boeing, 2018). The demand for training of new, student pilots has increased the use of recreational aircraft (RA) with technologically advanced cockpits in flight schools. The impact of RA based training compared to general aviation (GA) aircraft training on student mental workload is not well understood. This research investigated student pilot awareness of mental workload between technologically advanced cockpit equipped RA training with analog gauge equipped general aviation aircraft (GA) training.
There were a total of 25 aviation students, with a mean age of 24.4 years (17 males and 8 females), who completed in separate studies, self-reported assessment of mental workload using the NASA TLX combined with semi-structured interviews following both RA and GA flight training circuits, and simulation-based flight circuits. The results showed a significantly higher rating of mental workload across subscales of mental and physical demand on the NASATLX in recreational aviation aircraft training compared to general aviation aircraft. Similarly, thematic content analysis of semi-structured interviews identified that mental workload of the student pilots flying the recreational aircraft was perceived to be more than the general aviation aircraft, with pilots reporting that Landing, as a stage of flight, to be the most mentally demanding phase of flight for both RA and GA aircraft.
This research highlights an opportunity for further research into specific training for RA vs. GA aircraft training and provides an insight into the overall demand and potential barriers of using technology-based cockpits in the developmental stages of flight training. Further research is recommended to measure the physiological levels of mental workload during a flight to assess the real time effects of mental workload required of student pilots
Ku Telemetry Modulator for Suborbital Vehicles
A modulator utilizing the Ku-band instead of the usual S-band has been developed to improve transmission rates for suborbital platforms
Moving epidemic method (MEM) applied to virology data as a novel real time tool to predict peak in seasonal influenza healthcare utilisation. The Scottish experience of the 2017/18 season to date
Scotland observed an unusual influenza A(H3N2)-
dominated 2017/18 influenza season with healthcare
services under significant pressure. We report the
application of the moving epidemic method (MEM) to
virology data as a tool to predict the influenza peak
activity period and peak week of swab positivity in the
current season. This novel MEM application has been
successful locally and is believed to be of potential use
to other countries for healthcare planning and building
wider community resilience
Association of cerebral venous thrombosis with recent COVID-19 vaccination:case-crossover study using ascertainment through neuroimaging in Scotland
BackgroundTo investigate the association of primary acute cerebral venous thrombosis (CVT) with COVID-19 vaccination through complete ascertainment of all diagnosed CVT in the population of Scotland.MethodsCase-crossover study comparing cases of CVT recently exposed to vaccination (1-14 days after vaccination) with cases less recently exposed. Cases in Scotland from 1 December 2020 were ascertained through neuroimaging studies up to 17 May 2021 and diagnostic coding of hospital discharges up to 28 April 2021, linked to national vaccination records. The main outcome measure was primary acute CVT.ResultsOf 50 primary acute CVT cases, 29 were ascertained only from neuroimaging studies, 2 were ascertained only from hospital discharges, and 19 were ascertained from both sources. Of these 50 cases, 14 had received the Astra-Zeneca ChAdOx1 vaccine and 3 the Pfizer BNT162b2 vaccine. The incidence of CVT per million doses in the first 14 days after vaccination was 2.2 (95% credible interval 0.9 to 4.1) for ChAdOx1 and 1 (95% credible interval 0.1 to 2.9) for BNT162b2. The rate ratio for CVT associated with exposure to ChAdOx1 in the first 14 days compared with exposure 15-84 days after vaccination was 3.2 (95% credible interval 1.1 to 9.5).ConclusionsThese findings support a causal association between CVT and the AstraZeneca vaccine. The absolute risk of post-vaccination CVT in this population-wide study in Scotland was lower than has been reported for populations in Scandinavia and Germany; the explanation for this is not clear
Bio-Optical Sensors on Argo Floats
The general objective of the IOCCG BIO-Argo working group is to elaborate recommendations for establishing a framework for the future development of a cost-effective, bio-optical float network corresponding to the needs and expectations of the scientific community. In this context, our recommendations will necessarily be broad; they range from the identification of key bio-optical measurements to be implemented on floats, to the real-time management of the data flux resulting from the deployment of a "fleet of floats". Each chapter of this report is dedicated to an essential brick leading towards the goal of implementing a bio-optical profiling float network. The following topics are discussed in the Chapters listed below:
- Chapter 2 reviews the scientific objectives that could be tackled through the development of such networks, by allowing some of the gaps in the present spatio-temporal resolution of bio-optical variables to be progressively filled.
- Chapter 3 identifies the optical and bio-optical properties that are now amenable to remote and autonomous measurement through the use of optical sensors mounted on floats.
- Chapter 4 addresses the question of sensor requirements, in particular with respect to measurements performed from floats.
- Chapter 5 proposes and argues for the development of dedicated float missions corresponding to specific scientific objectives and relying on specific optical sensor suites, as well as on specific modes of float operation.
- Chapter 6 identifies technological issues that need to be addressed for the various bio-optical float missions to become even more cost-effective.
- Chapter 7 covers all aspects of data treatment ranging from the development of various quality control procedures (from real-time to delayed mode) to the architecture required for favoring easy access to data.
- Chapter 8 reviews the necessary steps and experience required before the operational implementation of different types of float networks can become a reality.JRC.H.5-Land Resources Managemen
