STOLAND
The STOLAND system includes air data, navigation, guidance, flight director (including a throttle flight director on the Augmentor Wing), 3-axis autopilot and autothrottle functions. The 3-axis autopilot and autothrottle control through parallel electric servos on both aircraft and on the augmentor wing, the system also interfaces with three electrohydraulic series actuators which drive the roll control surfaces, elevator and rudder. The system incorporates automatic configuration control of the flaps and nozzles on the augmentor wing and of the flaps on the Twin Otter. Interfaces are also provided to control the wing flap chokes on the Augmentor Wing and the spoilers on the Twin Otter. The STOLAND system has all the capabilities of a conventional integrated avionics system. Aircraft stabilization is provided in pitch, roll and yaw including control wheel steering in pitch and roll. The basic modes include altitude hold and select, indicated airspeed hold and select, flight path angle hold and select, and heading hold and select. The system can couple to TACAN and VOR/DME navaids for conventional radial flying
Content moderators’ strategies for coping with the stress of moderating content online
Content moderators are exposed to a range of stressors at work, including analysing content that has been flagged as harmful. However, not much is known about their specific coping strategies. Depth interviews were conducted with 11 content moderators exposed to child sexual abuse material (CSAM) as part of their job, and thematically analysed to investigate both individual coping strategies and those deployed organisationally. Results highlighted the importance of social support especially from colleagues. Supportive relationships fulfilled several needs including helping content moderators process emotions, normalise their reactions and reducing feelings of isolation. Additionally, the ability to create boundaries between work and home life was important for distancing and distracting themselves from the work. Moderators expressed a preference for mandatory, individual therapy with professionals who had specific experience supporting those exposed to CSAM and reported disclosure was hindered if not, due to worries about traumatising the therapist. How content moderators cope and can be further supported are discussed
Supporting Pre-Service Teachers in Becoming Reflective Practitioners Using Conversation and Professional Standards
A significant goal of teacher education is to support the development of reflective practitioners. This intention, however, is not easily achieved when after-the-fact recall and reporting are key features of pre-service teacher learning rather than critique and contemplation. This research reports on a small-scale pilot study evaluating a novel approach to help pre-service teachers develop reflective skills in order to both understand and address the requirements of the profession. The approach involved a set of Conversation Cards with a series of question-based prompts directly linked to the APSTs and designed to enhance reflective conversations. Focus group interview discussions unveiled the surprising ways in which the pre-service teachers used the question prompts, not only as tools for reflection but for planning lessons and preparing for professional discussions with mentors. This research provides insight into a creative and meaningful approach for integrating reflection, professional standards and classroom practice through professional experience
Eliminating helper phage from phage display
Phage display technology involves the display of proteins or peptides, as coat protein fusions, on the surface of a phage or phagemid particles. Using standard technology, helper phage are essential for the replication and assembly of phagemid particles, during library production and biopanning. We have eliminated the need to add helper phage by using 'bacterial packaging cell lines' that provide the same functions. These cell lines contain M13-based helper plasmids that express phage packaging proteins which assemble phagemid particles as efficiently as helper phage, but without helper phage contamination. This results in genetically pure phagemid particle preparations. Furthermore, by using constructs differing in the form of gene 3 that they contain, we have shown that the display, from a single library, can be modulated between monovalent (phagemid-like) and multivalent display (phage-like) without any further engineering. These packaging cells eliminate the use of helper phage from phagemid-based selection protocols; reducing the amount of technical preparation, facilitating automation, optimizing selections by matching display levels to diversity, and effectively using the packaged phagemid particles as means to transfer genetic information at an efficiency approaching 100%
