The GOAL-to-HAL/S translator specification

The specification sets forth a technical framework within which to deal with the transfer of specific GOAL features to HAL/S. Key technical features of the translator are described which communicate with the data bank, handle repeat statements, and deal with software interrupts. GOAL programs, databank information, and GOAL system subroutines are integrated into one GOAL in HAL/S. This output is fully compatible HAL/S source ready for insertion into the HAL/S compiler. The Translator uses a PASS1 to establish all the global data needed for the HAL/S output program. Individual GOAL statements are translated in PASS2. The specification document makes extensive use of flowcharts to specify exactly how each variation of each GOAL statement is to be translated. The specification also deals with definitions and assumptions, executive support structure and implementation. An appendix, entitled GOAL-to-HAL Mapping, provides examples of translated GOAL statements

The affine preservers of non-singular matrices

When K is an arbitrary field, we study the affine automorphisms of M_n(K) that stabilize GL_n(K). Using a theorem of Dieudonn\'e on maximal affine subspaces of singular matrices, this is easily reduced to the known case of linear preservers when n>2 or #K>2. We include a short new proof of the more general Flanders' theorem for affine subspaces of M_{p,q}(K) with bounded rank. We also find that the group of affine transformations of M_2(F_2) that stabilize GL_2(F_2) does not consist solely of linear maps. Using the theory of quadratic forms over F_2, we construct explicit isomorphisms between it, the symplectic group Sp_4(F_2) and the symmetric group S_6.Comment: 13 pages, very minor corrections from the first versio

Comment on "Geometric phase of the gyromotion for charged particles in a time-dependent magnetic field" [Phys. Plasmas 18, 072505 (2011)]

The geometric analysis of the gyromotion for charged particles in a time-dependent magnetic field by J. Liu and H. Qin [Phys. Plasmas 18, 072505 (2011)] is reformulated in terms of the spatial angles that represent the instantaneous orientation of the magnetic field. This new formulation, which includes the equation of motion for the pitch angle, clarifies the decomposition of the gyroangle-averaged equation of motion for the gyrophase into its dynamic and geometric contributions.Comment: 4 page

On the Theory of Superfluidity in Two Dimensions

The superfluid phase transition of the general vortex gas, in which the circulations may be any non-zero integer, is studied. When the net circulation of the system is not zero the absence of a superfluid phase is shown. When the net circulation of the vortices vanishes, the presence of off-diagonal long range order is demonstrated and the existence of an order parameter is proposed. The transition temperature for the general vortex gas is shown to be the Kosterlitz---Thouless temperature. An upper bound for the average vortex number density is established for the general vortex gas and an exact expression is derived for the Kosterlitz---Thouless ensemble.Comment: 22 pages, one figure, written in plain TeX, published in J.

Exploring mainstream secondary school leaderships' views and practices on the inclusion and permanent exclusion of students with social, emotional and mental health needs: A tension between performative pressures and inclusive practice

In the academic year 2019/2020, 6,500 children and young people (CYP) were permanently excluded from school; almost one-third of this population were identified with social, emotional and mental health (SEMH) needs (Department for Education [DfE], 2021a). For many, this disciplinary sanction leads to academic, social, health and financial disadvantages in addition to exacerbating their mental health needs (DfE, 2021a; Ford et al.,2018; Gill et al.,2017). The responsibility for decisions made to permanently exclude rests mainly with school leadership (DfE, 2012, 2017; Kulz, 2019). Therefore, this research explored the views and practices of senior leadership teams (SLTs) concerning the inclusion and permanent exclusion (PEX) of students with SEMH needs, using focus groups from three mainstream secondary schools in a local authority (LA) with a high PEX rate (DfE, 2016a, 2021b). A thematic analysis identified the overarching theme that 'SLTs grapple with their sense of agency over the inclusion and PEX of students with SEMH needs'. The discussion has been framed within Bronfenbrenner's (1979) ecological systems theory and has highlighted the tension between performativity and inclusion at various levels in the ecosystem. Within the macrosystem and exosystem, inclusion is inhibited by academic pressures, covert deficit discourses of disability and limited distribution of LA funding. Nevertheless, members of SLTs seek to promote inclusion within the mesosystem and microsystem by pursuing collaborative inter-organisational relations and facilitating containing relationships between the young people (YP) and significant others. Implications highlight that complex interactions within the ecosystem affect senior leaders sense of collective agency to promote the inclusion of students with SEMH needs, contributing to PEXs (Bandura, 1985, 2018). 2 Recommendations include the DfE to perhaps acknowledge the systemic causes of PEX then provide policy and funding to support inclusion. At the school level, SLTs may wish to share effective strategies and utilise educational psychologist support for training, supervision and the development of inclusive systems

Impact of Baseline Magnetic Resonance Imaging on Neurologic, Functional, and Safety Outcomes in Patients With Acute Traumatic Spinal Cord Injury

Study Design: Systematic review. Objective: To perform a systematic review to evaluate the utility of magnetic resonance imaging (MRI) in patients with acute spinal cord injury (SCI). Methods: An electronic search of Medline, EMBASE, the Cochrane Collaboration Library, and Google Scholar was conducted for literature published through May 12, 2015, to answer key questions associated with the use of MRI in patients with acute SCI. Results: The literature search yielded 796 potentially relevant citations, 8 of which were included in this review. One study used MRI in a protocol to decide on early surgical decompression. The MRI-protocol group showed improved outcomes; however, the quality of evidence was deemed very low due to selection bias. Seven studies reported MRI predictors of neurologic or functional outcomes. There was moderate-quality evidence that longer intramedullary hemorrhage (2 studies) and low-quality evidence that smaller spinal canal diameter at the location of maximal spinal cord compression and the presence of cord swelling are associated with poor neurologic recovery. There was moderate-quality evidence that clinical outcomes are not predicted by SCI lesion length and the presence of cord edema. Conclusions: Certain MRI characteristics appear to be predictive of outcomes in acute SCI, including length of intramedullary hemorrhage (moderate-quality evidence), canal diameter at maximal spinal cord compression (low-quality evidence), and spinal cord swelling (low-quality evidence). Other imaging features were either inconsistently (presence of hemorrhage, maximal canal compromise, and edema length) or not associated with outcomes. The paucity of literature highlights the need for well-designed prospective studies. © 2017, © The Author(s) 2017
