Perspectives on internal vs. external facilitation for implementing guidelines for recovery-oriented practice: a qualitative study.
Get PDFSeven organizations supporting adults with mental health challenges collaborated with researchers to implement Chapter Six of Canada's Guidelines for Recovery-Oriented Practice. An implementation strategy was developed that combined external facilitation, mixed Implementation Teams, a 12-meeting planning process, and ongoing coaching. This paper focuses on the facilitation component, specifically exploring participants' perspectives on internal versus external facilitation within Implementation Teams. Forty semi-structured individual online interviews were conducted with 32 members of Implementation Teams, including service users, providers, family members, managers, and knowledge users, along with eight researchers who acted as external facilitators. Participants discussed their experiences of implementing the guidelines supported by an external facilitator and were asked to consider how their experience may differ if it had been led by an internal facilitator. Thematic analysis identified seven themes relating to what was perceived as important about internal versus external facilitation: (1) Effect of facilitator position (external versus internal); (2) Flattening power hierarchies; (3) Enacting cultural shifts; (4) Understanding context; (5) Encouraging candour; (6) Building relationships, and (7) Internal facilitator identity and influence. These highlight how participants valued different skills, knowledge, and attributes in each scenario, with responses varying depending on the participant's identity. No clear preference emerged for either approach. Instead, participants debated the benefits and drawbacks of both, where insider knowledge vied with outsider neutrality for primacy. Whether facilitation is internal or external, its effectiveness relies on the facilitator's ability to establish rapport, develop allies, and foster unity between Implementation Team members and the implementation setting itself. A blended approach, which integrates the strengths of both internal and external facilitators, may offer the most effective model for supporting the implementation of recovery-oriented practice.

Reconstructing coseismic subsidence and uplift from coastal stratigraphic sections in the Jalisco subduction zone, Mexico
Get PDFRelative sea-level changes and evidence for a Holocene low stand in southern Greenland
Get PDFWe present new relative sea-level (RSL) data from southern Greenland, an area critical for understanding the Greenland Ice Sheet's (GrIS) sensitivity to climate change. Our RSL reconstruction from the inner Isortoq Fjord spans the last ∼10,000 years and is based on stratigraphic analyses, magnetic susceptibility, X-ray fluorescence core scanning, loss-on-ignition, macrofossil identification, and AMS radiocarbon dating of 10 sediment cores. Isolation and transgression sequences identified in lake and submerged basin sediments reveal a rapid RSL fall during the Early Holocene driven by crustal unloading in response to the retreat of the GrIS. During the Early Holocene, RSL dropped from the regional marine limit at ∼36 m above mean sea-level (MSL) to near present-day MSL by ∼9 cal. ka BP. A Middle Holocene low stand above 20 m below today's MSL at ∼6 cal. ka BP is followed by a gradual Late Holocene transgression, with sea level returning to present-day MSL sometime during the last millennium. Similar to records from Paamiut to the north and Qaqortoq and Nanortalik to the southeast, early isolation of low-lying basins in the Isortoq region reflects rapid isostatic rebound. In contrast, the Late Holocene transgression is more gradual and less well defined, likely reflecting a combination of local glacier and ice sheet advances and perhaps a broader isostatic signal from the retreat of the North American Ice Sheet Complex. Comparison with Huy3 model predictions shows that observed RSL changes in this region were of greater magnitude than simulated, highlighting the need for refined GIA modelling
Why does Research Evidence have So Little Impact on Education Policy?
No full textThis brief paper looks at the challenges of using research evidence to help formulate education policy. Over the last 30 years, governments and funders worldwide have sought to improve the quality of primary evidence produced by publicly-funded research (NRC 1999). And understanding of effective interventions to inform education policy (and practice) has improved somewhat since the creation of the US Institute of Education Sciences, the Education Endowment Foundation (EEF) in England, and other initiatives. There has also been progress in methods of synthesising research results, with the work of Evidence Centres and others (Davies and Silloway 2016). Evidence of what apparently works in real-life, or not, is increasingly available to research users for the first time. However, there is a long way to go, and many problems remain. Education policy-makers generally say that they want, and use, good evidence, but do not always act correspondingly (Gallway and Sheppard 2015). The paper looks at some of their problems and then at some possible ways forward
Structural Chirality and Natural Optical Activity across the α-to-β Phase Transition in SiO2 and AlPO4 from first-principles
No full textTerahertz spectroscopy with compact apochromatic metasurface optics
Get PDFTerahertz (THz) spectroscopy holds significant importance owing to the abundance of molecular and atomic fingerprint lines within this frequency range, enabling impactful applications in materials science, biology, and astronomy. Building on recent advancements in metasurface technology, we have developed a THz spectrometer that integrates a phase grating with two transmissive metasurfaces on a single platform. By mitigating chromatic dispersion and angular response limitations, the system incorporates a parallel focusing plane, simplifying integration with detector arrays, enhancing robustness, and reducing the requirement for incident light. Operating within the 1.23–1.43 THz range, the spectrometer achieves a theoretical resolution of 21 GHz, with a frequency resolution of 63 (f/Δf). This compact terahertz spectrometer offers scalable solutions for hyperspectral imaging and THz astronomical observation, demonstrating the transformative potential of metasurface technology for miniaturizing high-performance THz spectroscopy systems

No full textThe origin of the galaxy size–stellar metallicity relation – I. A semi-analytical perspective
Get PDFStellar metallicity encodes the integrated effects of gas inflow, star formation, and feedback-driven outflow, yet its connection to galaxy structure remains poorly understood. Using SDSS-IV MANGA , we present the direct observational evidence that, at fixed stellar mass, smaller central galaxies are systematically more metal-rich, with a Spearman’s rank correlation coefficient reaching Rs ≈−0 . 4. The semi-analytical model L-GALAXIES reproduces this anticorrelation, albeit with a stronger amplitude ( Rs ≈−0 . 8). Within this framework, the trend cannot be explained by differences in gravitational potential depth or star formation history. Instead, smaller galaxies attain higher stellar metallicities because their elevated star formation efficiencies accelerate chemical enrichment, and, at fixed stellar mass, they inhabit less massive haloes, which makes their recycled inflows more metal-rich. The gas-regulator model demonstrates that star formation efficiency affects stellar metallicity when the system has not long remained in equilibrium, which is shown to be the case for central galaxies with Mstar ≲ 1010 . 5 M in both L- GALAXIES and observation. The model also suggests a testable signature that, at fixed stellar mass, larger or lower metallicity galaxies should inhabit more massive haloes than their smaller and higher metallicity counterparts, providing a direct and testable imprint of the galaxy size–stellar metallicity relation on the galaxy–halo connection
Analytic continuation in the sinh-Gordon model
No full textWe study the analytic continuation of the finite-volume energy levels of the sinh-Gordon model. The structure is surprisingly rich, and in the small-coupling limit we find systematic patterns which suggest that a complete picture may be possible
Introduction to BeamWave Matrix for beam-forming and wave manipulation applications
No full textThis paper proposes a 2x4 reconfigurable structured network, the BeamWave Matrix, for beam-forming and wave manipulation applications. The matrix consists of a differential coupler, two equal-power dividers, and varactor-based phase shifters. Depending on the selected input port and the state of the phase shifters, phase gradients of [-90°, -45°, 0°, 45°, 90°] can be generated at the output ports. As one potential application, two copies of the matrix are used to feed a 1x4 dual-polarized array, enabling the generation of five reconfigurable beams with dual polarization. The sidelobe level (SLL) reaches -11 dB when the beam is steered to -45°and +45°, which is attributed to the absence of the phase quantization technique commonly employed in existing designs. In a second application, the [-90°, 0°, 90°] phase gradients of the matrix are used to feed a 2x2 array, manipulating the electromagnetic wave to excite the -1, 0, and +1 modes of Orbital Angular Momentum (OAM) waves. Additionally, two copies of the matrix are employed to generate dual-polarized OAM beams. It is worth noting that, to demonstrate the concept, the operating frequency of the matrix and antennas is set to 2.45 GHz. However, the matrix is flexible and can be designed to operate at any desired frequency
