What matters in learning communities for inclusive education: a cross-case analysis

© 2019 International Professional Development Association (IPDA). Implementing inclusive education requires on-going commitment to teachers’ professional learning. One way of implementing professional learning is to develop learning communities based on Lave and Wenger’s ideas of situated learning and learning as social practice. Learning communities, drawing on models of Professional Learning Communities and communities of practice, were designed to build capacity for inclusive teaching in two rural schools in Australia and a peri-urban school in South Africa. This paper reports on a multi-case study that involves a cross-case analysis of these three learning communities. We demonstrate that across the three cases, responsiveness to contextual exigencies matters, expertise matters and supportive networks matter. These findings are further illuminated by complexity theory which draws attention to learning communities operating at the confluence of a number of interacting systems, as well as the possibility of change where teacher learning occurs through the recontextualisation of knowledge and learning across boundaries. Our findings support situated learning that values collaboration to develop social and inclusive cultures and practice in schools. The findings also have the potential to inform planning for professional learning for inclusive education

Mid-IR spectroscopic instrumentation for point-of-care diagnosis using a hollow silica waveguide gas cell

Laser spectroscopy provides the basis of instrumentation developed for the diagnosis of infectious disease, via quantification of organic biomarkers that are produced by associated bacteria. The technology is centred on a multichannel pulsed quantum cascade laser system that allows multiple lasers with different wavelengths to be used simultaneously, each selected to monitor a different diagnostic biomarker. The instrument also utilizes a hollow silica waveguide (HSW) gas cell which has a very high ratio of interaction pathlength to internal volume. This allows sensitive detection of low volume gas species from small volume biological samples. The spectroscopic performance of a range of HSW gas cells with different lengths and bore diameters has been assessed using methane as a test gas and a best-case limit of detection of 0.26 ppm was determined. The response time of this cell was measured as a 1,000 sccm flow of methane passed through it and was found to be 0.75 s. These results are compared with those obtained using a multi-pass Herriot cell. A prototype instrument has been built and approved for clinical trials for detection of lung infection in acute-care patients via analysis of ventilator breath. Demonstration of the instrument for headspace gas analysis is made by monitoring the methane emission from bovine faeces. The manufacture of a hospital-ready device for monitoring biomarkers of infection in the exhaled breath of intensive care ventilator patients is also presented

SUPERSHARP - Segmented Unfolding Primary for Exoplanet Research via Spectroscopic High Angular Resolution Photography

We propose to search for biosignatures in the spectra of reflected light from about 100 Earth-sized planets that are already known to be orbiting in their habitable zones (HZ). For a sample of G and K type hosts, most of these planets will be between 25 and 50 milli-arcsec (mas) from their host star and 1 billion to 10 billion times fainter. To separate the planet's image from that of its host star at the wavelength (763nm) of the oxygen biosignature we need a telescope with an aperture of 16 metres. Furthermore, the intensity of the light from the host star at the position in the image of the exoplanet must be suppressed otherwise the exoplanet will be lost in the glare. This presents huge technical challenges. The Earth's atmosphere is turbulent which makes it impossible to achieve the required contrast from the ground at 763nm. The telescope therefore needs to be in space and to fit the telescope in the rocket fairing it must be a factor of 4 or more times smaller when folded than when operational. To obtain spectroscopy of the planet's biosignature at 763nm we need to use an integral field spectrometer (IFS) with a field of view (FOV) of 1000 x 1000 milli-arcsec (mas) and a spectral resolution of 100. This is a device that simultaneously takes many pictures of the exoplanet each at a slightly different wavelength which are then recorded as a data cube with two spatial dimensions and one wavelength dimension. In every data cube wavelength slice, the background light from the host star at the location of the planet image must be minimised. This is achieved via a coronagraph which blocks the light from the host star and active/adaptive optics techniques which continuously maintain very high accuracy optical alignment to make the images as sharp as possible. These are the technical challenges to be addressed in a design study.Comment: A proposal in response to the ESA New Science Ideas call. Sept 2016. 25 page

Mouse Phenome Database: towards a more FAIR-compliant and TRUST-worthy data repository and tool suite for phenotypes and genotypes.

The Mouse Phenome Database (MPD; https://phenome.jax.org; RRID:SCR_003212), supported by the US National Institutes of Health, is a Biomedical Data Repository listed in the Trans-NIH Biomedical Informatics Coordinating Committee registry. As an increasingly FAIR-compliant and TRUST-worthy data repository, MPD accepts phenotype and genotype data from mouse experiments and curates, organizes, integrates, archives, and distributes those data using community standards. Data are accompanied by rich metadata, including widely used ontologies and detailed protocols. Data are from all over the world and represent genetic, behavioral, morphological, and physiological disease-related characteristics in mice at baseline or those exposed to drugs or other treatments. MPD houses data from over 6000 strains and populations, representing many reproducible strain types and heterogenous populations such as the Diversity Outbred where each mouse is unique but can be genotyped throughout the genome. A suite of analysis tools is available to aggregate, visualize, and analyze these data within and across studies and populations in an increasingly traceable and reproducible manner. We have refined existing resources and developed new tools to continue to provide users with access to consistent, high-quality data that has translational relevance in a modernized infrastructure that enables interaction with a suite of bioinformatics analytic and data services

Mouse phenome database: curated data repository with interactive multi-population and multi-trait analyses.

The Mouse Phenome Database continues to serve as a curated repository and analysis suite for measured attributes of members of diverse mouse populations. The repository includes annotation to community standard ontologies and guidelines, a database of allelic states for 657 mouse strains, a collection of protocols, and analysis tools for flexible, interactive, user directed analyses that increasingly integrates data across traits and populations. The database has grown from its initial focus on a standard set of inbred strains to include heterogeneous mouse populations such as the Diversity Outbred and mapping crosses and well as Collaborative Cross, Hybrid Mouse Diversity Panel, and recombinant inbred strains. Most recently the system has expanded to include data from the International Mouse Phenotyping Consortium. Collectively these data are accessible by API and provided with an interactive tool suite that enables users\u27 persistent selection, storage, and operation on collections of measures. The tool suite allows basic analyses, advanced functions with dynamic visualization including multi-population meta-analysis, multivariate outlier detection, trait pattern matching, correlation analyses and other functions. The data resources and analysis suite provide users a flexible environment in which to explore the basis of phenotypic variation in health and disease across the lifespan

By staff and for staff: building, sustaining and empowering a community of practice in teaching and learning for all university staff

VicTeach was established in 2013 as a part of a Learning and Teaching Development initiative. VicTeach promotes cross-disciplinary dialogue between Victoria staff who are interested in pedagogy, sharing best practice, implementing new teaching approaches, and participating in and disseminating research on teaching and learning. It has become a particularly helpful network for academics interested in developing and informing their own teaching practice, but for whom education is not their main disciplinary focus; and for general staff supporting these academics in their teaching and student support. Regular bi-monthly meetings have addressed issues such as: new technologies and pedagogies, supporting Maori and Pasifika students, large classes, internships and placements, social media, flipped teaching, active learning and transition from high school. Meetings are held around the distributed VUW campus, streamed live, and archived for future-viewing. The community itself also continually tests, promotes, and profiles new technologies that all Victoria staff can use in teaching. Every seminar in the VicTeach programme attempts to include: • Best practice examples from a real teaching scenario Pedagogical grounding / research related to the topic, technology, or teaching concept Academic staff championing the topic/ technology / teaching concept Support staff with expertise in the area, or able to support development of this technology/ concept Time for discussion Over 200 academic and general staff members from across the university voluntarily subscribe to the VicTeach listserv and approximately 20-45 attend each event. The group is led by a volunteer steering committee consisting of academics from all Faculties, teaching award winners, and representatives from the Centre for Academic Development, Student Learning, the Library, and IT Support. This structure has been designed to ensure the organisation is sustainable and can continually respond to staff needs in learning and teaching. Future plans include the development and support of research hubs which will foster cross–disciplinary initiatives into particular aspects of teaching and learning. VicTeach appears to address an unfilled professional development need for Victoria University staff. In a survey conducted at the end of the first year the community reported that they had gained value from VicTeach, and most appreciated that it is pan-University, pan-staff, self-selecting, occurring at a regular time, gras

TOI-836 : a super-Earth and mini-Neptune transiting a nearby K-dwarf

Funding: TGW, ACC, and KH acknowledge support from STFC consolidated grant numbers ST/R000824/1 and ST/V000861/1, and UKSA grant ST/R003203/1.We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright (T = 8.5 mag), high proper motion (∼200 mas yr−1), low metallicity ([Fe/H]≈−0.28) K-dwarf with a mass of 0.68 ± 0.05 M⊙ and a radius of 0.67 ± 0.01 R⊙. We obtain photometric follow-up observations with a variety of facilities, and we use these data-sets to determine that the inner planet, TOI-836 b, is a 1.70 ± 0.07 R⊕ super-Earth in a 3.82 day orbit, placing it directly within the so-called ‘radius valley’. The outer planet, TOI-836 c, is a 2.59 ± 0.09 R⊕ mini-Neptune in an 8.60 day orbit. Radial velocity measurements reveal that TOI-836 b has a mass of 4.5 ± 0.9 M⊕, while TOI-836 c has a mass of 9.6 ± 2.6 M⊕. Photometric observations show Transit Timing Variations (TTVs) on the order of 20 minutes for TOI-836 c, although there are no detectable TTVs for TOI-836 b. The TTVs of planet TOI-836 c may be caused by an undetected exterior planet.Publisher PDFPeer reviewe
