    Background Increasing numbers of UK primary school exclusions (Department for Education, 2019a) are a cause for concern due to evidence demonstrating the negative outcomes common for these children (Parsons, Godfrey, Howlett, Hayden, & Martin, 2001). Therefore, an evidence-base to support interventions and practices effective in reducing school exclusion within mainstream primary schools is imperative to inform professional practice. Previous literature has indicated that staff attitudes are influential in mediating exclusionary practices (Hatton, 2013; Pomerantz, 2016). An intervention which seeks to build on such research and support school staff in order to avoid exclusionary practices is the Circles of Adults (CoA) group facilitation approach to problem-solving (Wilson & Newton, 2006). This study aims to investigate the nature of class teachers’ perceptions of a target student at risk of exclusion and explore the classroom context prior to their involvement in a CoA intervention. This research also seeks to explore the class teachers’ experience of the intervention itself and its perceived efficacy. Method Participants within this research were 4 class teachers working with 3 target students in different schools. Following a constructionist epistemology, semi-structured interviews were undertaken with class teachers prior to their involvement in a CoA intervention. Further semi-structured interviews were then held with 2 of these class teachers to follow up on their experiences of the intervention. Thematic Analysis has been used to explore themes within the data. Findings Findings indicated complexities in the way in which teachers construed their student, both prior to and following the CoA. The school context prior to a CoA demonstrated a system of interaction which disempowered the teacher and led to a sense of working in isolation, under immense pressure. The CoA effectively punctuated the system of the school context, enabling teachers to feel supported and part of a cohesive team, promoting more empathic responses within colleague and teacher-student interactions. The perceived value of the CoA intervention was, however, shown to be undermined when concrete actions did not follow

    Orbit Determination and Navigation of the Time History of Events and Macroscale Interactions during Substorms (THEMIS)

    This paper provides an overview of the launch and early orbit activities performed by the NASA Goddard Space Flight Center's (GSFC) Flight Dynamics Facility (FDF) in support of five probes comprising the Time History of Events and Macroscale Interactions during Substorms (THEMIS) spacecraft. The FDF was tasked to support THEMIS in a limited capacity providing backup orbit determination support for validation purposes for all five THEMIS probes during launch plus 30 days in coordination with University of California Berkeley Flight Dynamics Center (UCB/FDC)2. The FDF's orbit determination responsibilities were originally planned to be as a backup to the UCB/FDC for validation purposes only. However, various challenges early on in the mission and a Spacecraft Emergency declared thirty hours after launch placed the FDF team in the role of providing the orbit solutions that enabled contact with each of the probes and the eventual termination of the Spacecraft Emergency. This paper details the challenges and various techniques used by the GSFC FDF team to successfully perform orbit determination for all five THEMIS probes during the early mission. In addition, actual THEMIS orbit determination results are presented spanning the launch and early orbit mission phase. Lastly, this paper enumerates lessons learned from the THEMIS mission, as well as demonstrates the broad range of resources and capabilities within the FDF for supporting critical launch and early orbit navigation activities, especially challenging for constellation missions

    Orbit Determination and Navigation of the Solar Terrestrial Relations Observatory (STEREO)

    This paper provides an overview of the required upgrades necessary for navigation of NASA's twin heliocentric science missions, Solar TErestrial RElations Observatory (STEREO) Ahead and Behind. The orbit determination of the STEREO spacecraft was provided by the NASA Goddard Space Flight Center's (GSFC) Flight Dynamics Facility (FDF) in support of the mission operations activities performed by the Johns Hopkins University Applied Physics Laboratory (APL). The changes to FDF's orbit determination software included modeling upgrades as well as modifications required to process the Deep Space Network X-band tracking data used for STEREO. Orbit results as well as comparisons to independently computed solutions are also included. The successful orbit determination support aided in maneuvering the STEREO spacecraft, launched on October 26, 2006 (00:52 Z), to target the lunar gravity assists required to place the spacecraft into their final heliocentric drift-away orbits where they are providing stereo imaging of the Sun

    Mission Planning and Scheduling System for NASA's Lunar Reconnaissance Mission

    In the framework of NASA's return to the Moon efforts, the Lunar Reconnaissance Orbiter (LRO) is the first step. It is an unmanned mission to create a comprehensive atlas of the Moon's features and resources necessary to design and build a lunar outpost. LRO is scheduled for launch in April, 2009. LRO carries a payload comprised of six instruments and one technology demonstration. In addition to its scientific mission LRO will use new technologies, systems and flight operations concepts to reduce risk and increase productivity of future missions. As part of the effort to achieve robust and efficient operations, the LRO Mission Operations Team (MOT) will use its Mission Planning System (MPS) to manage the operational activities of the mission during the Lunar Orbit Insertion (LOI) and operational phases of the mission. The MPS, based on GMV's flexplan tool and developed for NASA with Honeywell Technology Solutions (prime contractor), will receive activity and slew maneuver requests from multiple science operations centers (SOC), as well as from the spacecraft engineers. flexplan will apply scheduling rules to all the requests received and will generate conflict free command schedules in the form of daily stored command loads for the orbiter and a set of daily pass scripts that help automate nominal real-time operations

    The Impact of Climate Change on Virginia\u27s Coastal Areas

    Full text link
    As part of HJ47/SJ47 (2020), the Virginia General Assembly directed the Joint Commission on Technology and Science (JCOTS) to study the “safety, quality of life, and economic consequences of weather and climate-related events on coastal areas in Virginia.” In pursuit of this goal, the commission was to “accept any scientific and technical assistance provided by the nonpartisan, volunteer Virginia Academy of Science, Engineering, and Medicine (VASEM). VASEM convened an expert study board with representation from the Office of the Governor, planning district commissions in coastal Virginia, The Port of Virginia, the Virginia Economic Development Partnership, state universities, private industry, and law firms. In producing the report, the board followed methods similar to those used by the National Academies of Science, Engineering, and Medicine by convening an expert committee tasked with studying and reporting on the topic. As a result, the report represents the views and perspectives of the study board members but was not submitted for public review or comment. This report is the product of those efforts. It finds that climate change will have an increasingly disruptive effect on people living in Virginia’s coastal areas during the 21st century — and that these disruptions will have repercussions across the Commonwealth. It includes an explanation of the physical forces driving climate change, an analysis of the current and projected effects of climate change on the Commonwealth, perspectives that legislators might consider as they face these challenges, and recommendations that could help Virginia implement more productive and effective strategies to address them
