Early Childhood Special Education in a Refugee Resettlement Community: Challenges and Innovative Practices

There has been a significant increase in the number of children who are culturally and linguistically diverse (CLD) who qualify for early childhood special education (ECSE) services (Banerjee & Guiberson, 2012). The current study investigates the challenges and innovative practices in the evaluation and (ECSE) services for preschool aged children who are refugees. Twenty-eight early childhood educators who work in a small refugee resettlement community participated in a qualitative study using semi-structured interviews resulting in themes regarding challenges and innovative practices. Challenges include: lack of validated assessments, wait time for evaluations, different cultural perspectives and family advocacy. Innovative practices include: assessing skills not dependent on language and including caregivers in evaluations. Implications for future research and teacher preparation are discussed

Progress in the study of CdZnTe strip detectors

We report new performance measurements and computer simulations of a sub-millimeter pitch CdZnTe strip detector under study as a prototype imaging spectrometer for astronomical x-ray and gamma-ray observations. The prototype is 1.5 mm thick with 375 micron strip pitch in both the x and y dimensions. Previously reported work included demonstrations of half-pitch spatial resolution (approximately 190 microns) and good energy resolution and spectral uniformity. Strip detector efficiency measurements have also been presented. A model that includes the photon interaction, carrier transport and the electronics was developed that qualitatively reproduced the measurements. The new studies include measurements of the CdZnTe transport properties for this prototype in an effort to resolve quantitative discrepancies between the measurements and the simulations. Measurements of charge signals produced by laser pulses and (alpha) -rays are used to determine these transport properties. These are then used in the model to predict gamma-ray efficiencies that are compared with the data. The imaging performance of the detector is studied by scanned laser and gamma beam spot measurements. The results support the model\u27s prediction of nearly linear sharing of the charge for interactions occurring in the region between electrodes. The potential for strip detectors with spatial resolution much finer than the strip pitch is demonstrated. A new design scheme for strip detectors is shortly discussed

INTRODUCTION: SUSTAINING THE LIFE OF THE POLIS.

How are publics of protection and care defined in African cities today? The effects of globalization and neo-liberal policies on urban space are well documented. From London to São Paulo, denationalization, privatization, offshoring and cuts in state expenditure are creating enclaves and exclusions, resulting in fragmented, stratified social geographies (see Caldeira 2000; Ong 2006; Harvey 2006; Murray 2011). 'Networked archipelagoes', islands connected by transnational circulations of capital, displace other spatial relations and imaginaries. Spaces of encompassment, especially, such as 'the nation' or simply 'society' as defined by inclusion within a whole, lose practical value and intellectual purchase as referents of citizenship (Gupta and Ferguson 2002; Ferguson 2005). In African cities, where humanitarian, experimental or market logics dominate the distribution of sanitation and healthcare, this fragmentation is particularly stark (see, for example, Redfield 2006, 2012; Fassin 2007; Bredeloup et al. 2008; Nguyen 2012). Privilege and crisis interrupt older contiguities, delineating spaces and times of exception. The 'public' of health is defined by survival or consumption, obscuring the human as bearer of civic rights and responsibilities, as inhabitants of 'objective' material worlds 'common to all of us' (Arendt 1958: 52). Is it possible, under these conditions, to enact and imagine public health as a project of citizens, animated in civic space

CdZnTe strip detectors as sub-millimeter resolution imaging gamma radiation spectrometers

We report γ-ray detection performance measurements and computer simulations of a sub-millimeter pitch CdZnTe strip detector. The detector is a prototype for γ-ray measurements in the range of 20-600 keV. The prototype is a 1.5 mm thick, 64×64 orthogonal stripe CdZnTe detector of 0.375 mm pitch in both dimensions, with approximately one square inch of sensitive area. Using discrete laboratory electronics to process signals from an 8×8 stripe region of the prototype we measured good spectroscopic uniformity and sub-pitch (~0.2 mm) spatial resolution in both x and y dimensions. We present below measurements of the spatial uniformity, relative timing and pulse height of the anode and cathode signals. We simulated the photon interactions and signal generation in the strip detector and the test electronics and we compare these results with the data. The data indicate that cathode signal-as well as the anode signal-arises more strongly from the conduction electrons rather than the holes

Performance of CdZnTe strip detectors as sub-millimeter resolution imaging gamma radiation spectrometers

We report & gamma;-ray detection performance measurements and computer simulations of a sub-millimeter pitch CdZnTe strip detector. The detector is a prototype for & gamma;-ray astronomy measurements in the range of 20-200 keV. The prototype is a 1.5 mm thick, 64×64 orthogonal stripeCdZnTe detector of 0.375 mm pitch in both dimensions, with approximately one square inch of sensitive area. Using discrete laboratory electronics to process signals from an 8×8 stripe region of the prototype we measured good spectroscopic uniformity and sub-pitch (~0.2 mm) spatial resolution in both x and y dimensions. We present below measurements of the spatial uniformity, relative timing and pulse height of the anode and cathode signals, and the photon detection efficiency. We also present a technique for determining the location of the event in the third dimension (depth). We simulated the photon interactions and signal generation in the strip detector and the test electronics and we compare these results with the data. The data indicate that the cathode signal-as well as the anode signal-arises more strongly from the conduction electrons rather than the holes

The eSMAF: a software for the assessment and follow-up of functional autonomy in geriatrics

BACKGROUND: Functional status or disability forms the core of most assessment instruments used to identify mix and level of resources and services needed by older adults who possess common characteristics. The Functional Autonomy Measurement System (SMAF) is a 29-item scale measuring functional ability in five different areas. It has been recommended for use for home care, for allocation of chronic beds, for developing care plans in institutional settings and for epidemiological and evaluative studies. The SMAF can also be used with a case-mix classification system (Iso-SMAF) to allocate resources based on patients' functional autonomy characteristics. The objective of this project was to develop a software version of the SMAF to facilitate the evaluation of the functional status of older adults in health services research and to optimize the clinical decision-making process. RESULTS: The eSMAF was developed over an 24-month period using a modified waterfall software engineering process. Requirements and functional specifications were determined using focus groups of stakeholders. Different versions of the software were iteratively field-tested in clinical and research environments and software adaptations made accordingly. User documentation and online help were created to assist the deployment of the software. The software is available in French or English versions under a 30-day unregistered demonstration license or a free restricted registered academic license. It can be used locally on a Windows-based PC or over a network to input SMAF data into a database, search and aggregate client data according to clinical and/or administrative criteria, and generate summary or detailed reports of selected data sets for print or export to another database. CONCLUSION: In the last year, the software has been successfully deployed in the clinical workflow of different institutions in research and clinical applications. The software performed relatively well in terms of stability and performance. Barriers to implementation included antiquated computer hardware, low computer literacy and access to IT support. Key factors for the deployment of the software included standardization of the workflow, user training and support

Does inter-vertebral range of motion increase after spinal manipulation? A prospective cohort study.

Background: Spinal manipulation for nonspecific neck pain is thought to work in part by improving inter-vertebral range of motion (IV-RoM), but it is difficult to measure this or determine whether it is related to clinical outcomes. Objectives: This study undertook to determine whether cervical spine flexion and extension IV-RoM increases after a course of spinal manipulation, to explore relationships between any IV-RoM increases and clinical outcomes and to compare palpation with objective measurement in the detection of hypo-mobile segments. Method: Thirty patients with nonspecific neck pain and 30 healthy controls matched for age and gender received quantitative fluoroscopy (QF) screenings to measure flexion and extension IV-RoM (C1-C6) at baseline and 4-week follow-up between September 2012-13. Patients received up to 12 neck manipulations and completed NRS, NDI and Euroqol 5D-5L at baseline, plus PGIC and satisfaction questionnaires at follow-up. IV-RoM accuracy, repeatability and hypo-mobility cut-offs were determined. Minimal detectable changes (MDC) over 4 weeks were calculated from controls. Patients and control IV-RoMs were compared at baseline as well as changes in patients over 4 weeks. Correlations between outcomes and the number of manipulations received and the agreement (Kappa) between palpated and QF-detected of hypo-mobile segments were calculated. Results: QF had high accuracy (worst RMS error 0.5o) and repeatability (highest SEM 1.1o, lowest ICC 0.90) for IV-RoM measurement. Hypo-mobility cut offs ranged from 0.8o to 3.5o. No outcome was significantly correlated with increased IV-RoM above MDC and there was no significant difference between the number of hypo-mobile segments in patients and controls at baseline or significant increases in IV-RoMs in patients. However, there was a modest and significant correlation between the number of manipulations received and the number of levels and directions whose IV-RoM increased beyond MDC (Rho=0.39, p=0.043). There was also no agreement between palpation and QF in identifying hypo-mobile segments (Kappa 0.04-0.06). Conclusions: This study found no differences in cervical sagittal IV-RoM between patients with non-specific neck pain and matched controls. There was a modest dose-response relationship between the number of manipulations given and number of levels increasing IV-RoM - providing evidence that neck manipulation has a mechanical effect at segmental levels. However, patient-reported outcomes were not related to this

The development of a stakeholder-endorsed national strategic plan for advancing pain education across Canadian physiotherapy programs

Abstract Background The Canadian Pain Task Force recently advanced an action plan calling for improved entry-level health professional pain education. However, there is little research to inform the collaboration and coordination across stakeholders that is needed for its implementation. Aims This manuscript reports on the development of a stakeholder-generated strategic plan to improve pain education across all Canadian physiotherapy (PT) programs. Methods Participants included representatives from the following stakeholder groups: people living with pain (n = 1); PT students and recent graduates (n = 2); educators and directors from every Canadian PT program (n = 24); and leaders of Canada?s national PT professional association (n = 2). Strategic priorities were developed through three steps (1) stakeholder-generated data was collected and analyzed; (2) a draft strategic plan was developed and refined; and (2) stakeholder endorsement of the final plan was assessed. The project was primarily implemented online, between 2016 and 2018. Results The plan was developed through five iterative versions. Stakeholders unanimously endorsed a plan that included five priorities focusing on uptake of best evidence across (1) national PT governance groups and (2) within individual PT programs; (3) partnering with people living with pain in pain education; (4) advocacy for the PT role in pain management; and (5) advancing pain education research. Conclusion This plan is expected to help Canadian stakeholders work toward national improvements in PT pain education and to serve as a useful template for informing collaboration on entry-level pain education within other professions and across different geographic regions
