The Needle is Moving in CA K-8 Science: Integration with ELA, Integration of the Sciences, and Returning Science as a K-8 Core Subject

This first EII evaluation publication discusses one of the major shifts above, namely the shift to integrated instruction. The integration of science and ELA is the focus of one section, and the integration of the science disciplines (i.e., earth/space, life, and physical) inherent in the MS Integrated Model is the focus of the second. Also discussed at length in this publication is a fundamental shift that is not listed above, but is equally, if not more, important: the need to teach science in the first place. In order for any of the targeted shifts to take place, teachers must devote time to teaching science on a regular basis

Accuracy and feasibility of dual fluoroscopy and model-based tracking to quantify in vivo hip kinematics during clinical exams

pre-printAccurate measurements of in-vivo hip kinematics may elucidate the mechanisms responsible for impaired function and chondrolabral damage in hips with femoroacetabular impingement (FAI). The objectives of this study were to quantify the accuracy and demonstrate the feasibility of using dual fluoroscopy to measure in-vivo hip kinematics during clinical exams used in the assessment of FAI. Steel beads were implanted into the pelvis and femur of two cadavers. Specimens were imaged under dual fluoroscopy during the impingement exam, FABER test, and rotational profile. Bead locations measured with model-based tracking were compared to those measured using dynamic radiostereometric analysis. Error was quantified by bias and precision, defined as the average and standard deviation of the differences between tracking methods, respectively. A normal male volunteer was also imaged during clinical exams. Bias and precision along a single axis did not exceed 0.17 and 0.21 mm, respectively. Comparing kinematics, positional error was less than 0.48 mm and rotational error was less than 0.58°. For the volunteer, kinematics were reported as joint angles and bone-bone distance. These results demonstrate that dual fluoroscopy and model-based tracking can accurately measure hip kinematics in living subjects during clinical exams of the hip

Design of the advanced regional aircraft, the DART-75

This design analysis is intended to show the capabilities of the DART-75, a 75 passenger medium-range regional transport. Included are the detailed descriptions of the structures, performance, stability and control, weight and balance, and engine design. The design should allow for the DART to become the premier regional aircraft of the future due to some advanced features like the canard, semi-composite construction, and advanced engines

Quantifying the incidence of lower limb amputation in people with and without diabetes in Wales between 2008–2018

Background: There is variance in the incidence of lower extremity amputation across and within countries including within the UK. National data shows up to a fourfold variance in the amputation rate throughout the regions of England and differences in amputation incidence have been reported in Scotland and Ireland. Lower extremity amputation rate has yet to be documented within Wales. The aim of this cohort study was to examine trends in diabetes and non-diabetes related lower extremity amputation incidence within the Welsh population and to examine the influence of diabetes on the relative risk of amputation. Materials and Methods: All first-time amputations between 2008-2018 were extracted from SAIL, a repository of all routine medical data of residents of Wales. People with diabetes were identified using an algorithm utilising data from several clinical and non-clinical sources. Crude and direct age and sex adjusted incidences were estimated over time. Results: Over the period 3505 major amputations and 4335 minor amputations occurred. The diabetes population greater than 17 years of age increased by 29.4% from 143,595 in 2008 to 206,818 in 2018. There was a statistically significant rate reduction in major amputation in both populations. In the diabetes population the number of major amputations reduced from 6.9 [5.5–8.5]/10 000 person years (PY) in 2008 to 4.9 [5.4–6.2]/10 000 PY in 2018. However, for major amputation, the risk of incident amputation in people with diabetes was 7.3 fold higher [7.1–7.5] than those without diabetes. The relative risk of minor amputation for those with diabetes was higher at 11.9 [11.8 –1.01]. There was no reduction in this risk over the period. Conclusion: This study found that rates of major amputation decreased over the study period but the risk of amputation for persons with diabetes remained substantial. As the population with diabetes increases so do crude rates of amputation, providing a substantial financial and societal cost to the Welsh Population

Tri-Design: Coordination between Healthcare, Design, and Regulatory Communities

This paper discusses the approaches undertaken by organizations, coordination between healthcare, design, and regulatory communities, to respond to the needs for the crisis and bring about models for agile innovation and of disease mitigation. The COVID-19 Design Innovation was born at the core of a major university to operate as a hub for innovation.  In an effort to connect designers, makers, and healthcare professionals, the initiative converged with the main motivation is to be organized in collective efforts with the crisis and deliver creative design innovations. Several products were brought about through the initiative efforts: off the shelf solutions and community driven, hybrid prototyping (reutilizing parts), distributed manufacturing, material investigations, and rapid prototyping for turning labs as manufacturing facilities. As solutions reached refinement, healthcare called for volume, solutions were brought to the community as a rapid response to the crisis. While challenges imposed by time and production, the crisis help coordinate efforts to be agile networks of stakeholders working towards a common goal, hacking the crisis by design

Examining student-designed games through Suits’ theory of games

This paper documents how a unit of student-designed games can create a more meaningful version of physical education (PE) for disengaged students, a version that enhances the educational legitimacy of the subject matter by affording it worth in and of itself rather than being justified for other, extrinsic or instrumental reasons. Furthermore, it seeks to develop new knowledge relating to the conduct of game instruction within PE, by using Suits’ theory of games. Drawing on Suits’ theory, we develop a conceptual model that is intended to represent the hierarchical processes that occur in gameplay through student-designed games. This model is then tested via examination of the experiences of a cohort of teachers and their year 10 students from a mixed secondary school in the greater London area. From our discussions with the students, it is argued that the key focus of the games that these students were used to playing was the need to ‘play the game well’. By contrast, we suggest that it is possible to provide more meaningful experiences to students if a more philosophically driven and less efficiency-driven approach to games is taken, following Suits’ lead more closely. By exploring the loop between and around lusory means, lusory goals and constitutive rules (the aspects of Suits’ theory that have been shown to represent student-designed games), students engage with a more meaningful games experience than simply playing the game well. This ‘new’ approach to games may offer counterbalance to the ideological tendencies now emphasized in countries and contexts that celebrate instrumental outcomes of performative PE and sport rather than affording worth in and of itself to the curriculum’s subject matter

Automating Hyperspectral Data for Rapid Response in Volcanic Emergencies

In a volcanic emergency, time is of the essence. It is vital to quantify eruption parameters (thermal emission, effusion rate, location of activity) and distribute this information as quickly as possible to decision-makers in order to enable effective evaluation of eruption-related risk and hazard. The goal of this work was to automate and streamline processing of spacecraft hyperspectral data, automate product generation, and automate distribution of products. Visible and Short-Wave Infrared Images of volcanic eruption in Iceland in May 2010." class="caption" align="right">The software rapidly processes hyperspectral data, correcting for incident sunlight where necessary, and atmospheric transmission; detects thermally anomalous pixels; fits data with model black-body thermal emission spectra to determine radiant flux; calculates atmospheric convection thermal removal; and then calculates total heat loss. From these results, an estimation of effusion rate is made. Maps are generated of thermal emission and location (see figure). Products are posted online, and relevant parties notified. Effusion rate data are added to historical record and plotted to identify spikes in activity for persistently active eruptions. The entire process from start to end is autonomous. Future spacecraft, especially those in deep space, can react to detection of transient processes without the need to communicate with Earth, thus increasing science return. Terrestrially, this removes the need for human intervention
