In Sicht von oben, ‘Powers of Ten’ und Bildpolitiken der Vertikalität (Spector Books, Leipzig, 2022) German media theorist and curator Vera Tollmann analyses the power aspects of the technical view from above. The context here is not so much the first manned flight with a balloon in 1783 in Paris but the iconic 1968/77 short film Powers of Ten by Charles and Ray Eames, which can be considered the first virtual camera trip. Her study can be seen as material image analysis along the lines of Friedrich Kittler’s optical media and is strongly informed by the work of Hito Steyerl. Part one deals with the verticality of the image regime, while part two focuses on the vertical aspect and part three theorizes scale and scalability.

Educational innovations often tend to fail, mainly because teachers and school principals do not feel involved or are not allowed to have a say. Angela de Jong's dissertation shows the importance of school principals and teachers leading 'collaborative innovation' together. Collaborative innovation requires a collaborative, distributed approach involving both horizontal and vertical working relationships in a school. Her research shows that teams with more distributed leadership have a more collaborative 'spirit' to improve education. Team members move beyond formal (leadership) roles, and work more collectively on school-wide educational improvement from intrinsic motivation. De Jong further shows that school principals seek a balance in steering and providing space. She distinguished three leadership patterns: Team Player, Key Player, Facilitator. Team players in particular are important for more collaborative innovation in a school. They balance between providing professional space to teachers (who look beyond their own classroom) and steering for strategy, frameworks, boundaries, and vision. This research took place in schools working with the program of Foundation leerKRACHT, a program implemented by more than a thousand schools (primary, secondary, and vocational education). The study recommends, towards school principals and teachers, and also towards trainers, policymakers, and school board members, to reflect more explicitly on their roles in collaborative innovation and talk about those roles.
Over 40% of nursing home residents in the Netherlands are estimated to have visual impairments. In this study, light conditions in Dutch nursing homes were assessed in terms of horizontal and vertical illuminances and colour temperature. Results showed that in the seven nursing homes vertical illuminances in common rooms fell significantly below the 750 lx reference value in at least 65% of the measurements. Horizontal illuminance measurements in common rooms showed a similar pattern. At least 55% of the measurements were below the 750 lx threshold. The number of measurements at the window zone was significantly higher than the threshold level of 750 lx. Illuminances in the corridors fell significantly below the 200 lx threshold in at least three quarters of the measurements in six of the seven nursing homes. The colour temperature of light fell significantly below the reference value for daylight of 5000 K with median scores of 3400 to 4500 K. A significant difference in colour temperature was found between recently constructed nursing homes and some older homes. Lighting conditions of the examined nursing homes were poor. With these data, nursing home staff have the means to improve the lighting conditions, for instance, by encouraging residents to be seated next to a window when performing a task or during meals.
