TRADING IN EDUCATION: THE AGREEMENT ON INTERNAL TRADE, LABOUR MOBILITY AND TEACHER CERTIFICATION IN CANADA

Canada‘s provincial and territorial governments are committed to implement the Labour Mobility chapter of the Agreement on Internal Trade (AIT) in 2009. This article examines the implications of this agreement for teacher certification and teacher education programs. It argues that the full impact of AIT will not be immediately apparent, but over the long term the new circumstances have the potential to bring about profound changes to public education. This is a two-part paper: the first half examines the development of the Agreement on Internal Trade with reference to its labour mobility provisions. The second half lays out what we see as four troubling aspects of the Agreement.

School Boards and Education Finance in Manitoba: The Politics of Equity, Access and Local Autonomy

This paper provides an analysis of current educational finance debates in Manitoba within a broader discussion of the essential character of public education in Canada. Arguing that public accessibility and equity, public funding, and public control constitute three touchstones of public education, the paper describes the Manitoba debates over provincial and local funding of schools and the use of property taxes to fund education and analyzes them in relation to these criteria. Significant continued local school board funding from property taxes, along with a greater commitment to provincial equalization initiatives, is the direction that the paper suggests offers the greatest potential for sustaining and nurturing a strong publicly funded school system characterized by both public accessibility and public control.

Assessing Master Gardener Volunteers’ Involvement in and Knowledge of Food Preservation

Accessing science-based practices for safe-home food preservation (FP) can prevent unnecessary foodborne illness. An Extension program called Grow It, Eat It, Preserve It allows trained Extension agents to teach and advise on FP topics. Meanwhile, the Home & Garden Information Center delivers science-based gardening education, supporting the Master Gardener Volunteer Program (MG), increasing community outreach. MGs conduct the Grow It, Eat It, Preserve It partner program, Grow It Eat It, which teaches residents to grow edible gardens. MGs are not legally trained in FP, and a knowledge gap exists regarding how often MGs are asked FP questions during community events and what resources they provide to clients. An online survey was administered to 1,810 active MGs in Maryland, providing insight on MGs’ current knowledge and community interactions pertaining to FP. A total of 586 MGs responded to the survey. Results indicated that MGs were asked FP questions during community events (65.5%) and often went beyond the scope of their training to provide non-Extension resources for FP. Most MGs were unsure whether FP workshops took place in their county Extension office (65.8%). The survey results can improve cross-programming communication and inform future MG training, marketing, and programming

Profiles of SUMO and ubiquitin conjugation in an Alzheimer's disease model

► Global levels of ubiquitinated proteins increased in the hippocampus of Tg2576 mice. ► No global changes in either SUMO-1 or SUMO-2/3 conjugation in any brain regions analysed. ► SUMO conjugating and deconjugating enzymes, UBC9 and SENP-1, unaltered in Tg2576 mice. ► Total levels of AMPA and kainate receptors were also unaffected in Tg2576 mice. ► Posttranslational modification by ubiquitin may play a role in Alzheimer's disease

A Census of Baryons and Dark Matter in an Isolated, Milky Way-sized Elliptical Galaxy

We present a study of the dark and luminous matter in the isolated elliptical galaxy NGC720, based on deep X-ray observations made with Chandra and Suzaku. The gas is reliably measured to ~R2500, allowing us to place good constraints on the enclosed mass and baryon fraction (fb) within this radius (M2500=1.6e12+/-0.2e12 Msun, fb(2500)=0.10+/-0.01; systematic errors are <~20%). The data indicate that the hot gas is close to hydrostatic, which is supported by good agreement with a kinematical analysis of the dwarf satellite galaxies. We confirm a dark matter (DM) halo at ~20-sigma. Assuming an NFW DM profile, our physical model for the gas distribution enables us to obtain meaningful constraints at scales larger than R2500, revealing that most of the baryons are in the hot gas. We find that fb within Rvir is consistent with the Cosmological value, confirming theoretical predictions that a ~Milky Way-mass (Mvir=3.1e12+/-0.4e12 Msun) galaxy can sustain a massive, quasi-hydrostatic gas halo. While fb is higher than the cold baryon fraction typically measured in similar-mass spiral galaxies, both the gas fraction (fg) and fb in NGC720 are consistent with an extrapolation of the trends with mass seen in massive galaxy groups and clusters. After correcting for fg, the entropy profile is close to the self-similar prediction of gravitational structure formation simulations, as observed in galaxy clusters. Finally, we find a strong heavy metal abundance gradient in the ISM similar to those observed in massive galaxy groups.Comment: 23 pages, 13 figures, 4 tables.

Evidence synthesis to inform model-based cost-effectiveness evaluations of diagnostic tests: a methodological systematic review of health technology assessments

Background: Evaluations of diagnostic tests are challenging because of the indirect nature of their impact on patient outcomes. Model-based health economic evaluations of tests allow different types of evidence from various sources to be incorporated and enable cost-effectiveness estimates to be made beyond the duration of available study data. To parameterize a health-economic model fully, all the ways a test impacts on patient health must be quantified, including but not limited to diagnostic test accuracy. Methods: We assessed all UK NIHR HTA reports published May 2009-July 2015. Reports were included if they evaluated a diagnostic test, included a model-based health economic evaluation and included a systematic review and meta-analysis of test accuracy. From each eligible report we extracted information on the following topics: 1) what evidence aside from test accuracy was searched for and synthesised, 2) which methods were used to synthesise test accuracy evidence and how did the results inform the economic model, 3) how/whether threshold effects were explored, 4) how the potential dependency between multiple tests in a pathway was accounted for, and 5) for evaluations of tests targeted at the primary care setting, how evidence from differing healthcare settings was incorporated. Results: The bivariate or HSROC model was implemented in 20/22 reports that met all inclusion criteria. Test accuracy data for health economic modelling was obtained from meta-analyses completely in four reports, partially in fourteen reports and not at all in four reports. Only 2/7 reports that used a quantitative test gave clear threshold recommendations. All 22 reports explored the effect of uncertainty in accuracy parameters but most of those that used multiple tests did not allow for dependence between test results. 7/22 tests were potentially suitable for primary care but the majority found limited evidence on test accuracy in primary care settings. Conclusions: The uptake of appropriate meta-analysis methods for synthesising evidence on diagnostic test accuracy in UK NIHR HTAs has improved in recent years. Future research should focus on other evidence requirements for cost-effectiveness assessment, threshold effects for quantitative tests and the impact of multiple diagnostic tests
