Resilience, Reflection and Reflexivity

Historically the teacher resilience literature has tended to focus on the individual (Day, 2017), their ability to manage stressors and risk factors and to draw on protective factors (Howard and Johnson, 2004). More recently the emphasis has shifted from analysis of the individual, towards understandings which emphasise the interaction between individuals and their environments (Ungar, 2012). Focussed more on the latter rather than the former, this chapter moves away from the potentially damaging effects of a ‘pull yourself together’ mentality, in favour of analysis which contextualises teacher resilience. Teacher resilience is viewed more in terms of the space where an individual’s capacity to navigate challenges interacts over time with their personal and professional contexts (Beltman, 2015). The desired outcome of this meeting between individual and context is a teacher who experiences professional engagement and growth, commitment, enthusiasm, satisfaction, and wellbeing (Beltman, 2015) and thus is able to act in a personally, socially and emotionally responsible way. The nexus between professional challenge and teacher satisfaction is explored through two case studies presented in this chapter and the subsequent discussion which addresses the inclusion of children with additional needs (both special educational needs and/or disability (SEND) and able and talented).N/

Researching reciprocal leadership: using the consciousness quotient inventory (CQ-i) as a pilot methodology to explore leadership with the context of a school–university partnership.

This article looks at the potential of using an online self-completing inventory that measures leadership consciousness awareness. The Consciousness Quotient inventory (CQ-i) has been developed to encourage leaders to be more conscious of their ability to be accountable and responsible for their leadership practice. The CQ-i as a method for researching leadership is piloted here between a university academic and a primary headteacher in the context of a school–university partnership. Pilot outcomes reveal that the inventory can be used as an evaluation of partnership work and ways of thinking about leadership on two levels: the personal and the partnership. The method is somewhat limited by a lack of distinctive criteria for personal domain statements and the absence of an overall profile outcome for the CQ score. Its strength lies in the way the outcomes of the inventory can be used as a starting point for personal reflection on leadership and as a vehicle for discussing a range of different ways of leadership working within different settings, such as school and university contexts.N/

GMTIFS: The adaptive optics beam steering mirror for the GMT integral-field spectrograph

To achieve the high adaptive optics sky coverage necessary to allow the GMT Integral-Field Spectrograph (GMTIFS) to access key scientific targets, the on-instrument adaptive-optics wavefront-sensing (OIWFS) system must patrol the full 180 arcsecond diameter guide field passed to the instrument. The OIWFS uses a diffraction limited guide star as the fundamental pointing reference for the instrument. During an observation the offset between the science target and the guide star will change due to sources such as flexure, differential refraction and non-sidereal tracking rates. GMTIFS uses a beam steering mirror to set the initial offset between science target and guide star and also to correct for changes in offset. In order to reduce image motion from beam steering errors to those comparable to the AO system in the most stringent case, the beam steering mirror is set a requirement of less than 1 milliarcsecond RMS. This corresponds to a dynamic range for both actuators and sensors of better than 1/180,000. The GMTIFS beam steering mirror uses piezo-walk actuators and a combination of eddy current sensors and interferometric sensors to achieve this dynamic range and control. While the sensors are rated for cryogenic operation, the actuators are not. We report on the results of prototype testing of single actuators, with the sensors, on the bench and in a cryogenic environment. Specific failures of the system are explained and suspected reasons for them. A modified test jig is used to investigate the option of heating the actuator and we report the improved results. In addition to individual component testing, we built and tested a complete beam steering mirror assembly. Testing was conducted with a point source microscope, however controlling environmental conditions to less than 1 micron was challenging. The assembly testing investigated acquisition accuracy and if there was any un-sensed hysteresis in the system. Finally we present the revised beam steering mirror design based on the outcomes and lessons learnt from this prototyping

GMTIFS: The Giant Magellan Telescope integral fields spectrograph and imager

GMTIFS is the first-generation adaptive optics integral-field spectrograph for the GMT, having been selected through a competitive review process in 2011. The GMTIFS concept is for a workhorse single-object integral-field spectrograph, operating at intermediate resolution (R~5,000 & 10,000) with a parallel imaging channel. The IFS offers variable spaxel scales to Nyquist sample the diffraction limited GMT PSF from λ ~ 1-2.5 μm as well as a 50 mas scale to provide high sensitivity for low surface brightness objects. The GMTIFS will operate with all AO modes of the GMT (Natural guide star - NGSAO, Laser Tomography – LTAO, and, Ground Layer - GLAO) with an emphasis on achieving high skycoverage for LTAO observations. We summarize the principle science drivers for GMTIFS and the major design concepts that allow these goals to be achieved

Avalanche photo diodes in the observatory environment: Lucky imaging at 1-2.5 microns

The recent availability of large format near-infrared detectors with sub-election readout noise is revolutionizing our approach to wavefront sensing for adaptive optics. However, as with all near infrared detector technologies, challenges exist in moving from the comfort of the laboratory test bench into the harsh reality of the observatory environment. As part of the broader adaptive optics program for the GMT, we are developing a near-infrared Lucky Imaging camera for operational deployment at the ANU 2.3 m telescope at Siding Spring Observatory. The system provides an ideal test-bed for the rapidly evolving Selex/SAPHIRA eAPD technology while providing scientific imaging at angular resolution rivalling the Hubble Space Telescope at wavelengths λ = 1.3-2.5 μ
