Download Article A GREAT BRITISH POLAR EXPLORER EMERGING TECHNOLOGY The rapid melting of polar ice caps could have catastrophic consequences for oceans across the globe. To understand the role that the polar oceans play in our changing world, Britain is debuting the RRS Sir David Attenborough – one of the most advanced polar research vessels in the world, which will operate in some of the most remote and inhospitable regions on Earth. Science writer Sarah Griffiths discovered the ship’s impressive features. vessel’s ability to support science most engineering challenges. with additional snow cover, in extreme environments.

By doing this, less ice will follow the water flow at the bottom of the vessel and end up in the propellers, which creates noise, power peaks and loss in thrust, as well as in the broken channel behind the vessel. This area should be as open as possible to allow towing of equipment for scientific work and reversing if necessary.

    BHSA Newsletter Autumn Term 2019 Edition 05 Welcome Welcome to our October 2019 Newsletter. We have had an incredibly busy and positive start to this aca- demic year at BHSA . I hope you enjoy reading about some of the many opportunities the girls have em- braced so far this term. It is virtually impossible to New junior school council select any favourites, but a real highlight in the Sen- ior School was welcoming Deana Puccio form The Rap Project UK to BHSA. Her presentations to all girls from Years 7 to 13 were both powerful and in- spiring, delivering an important message to every single one of us. The girls are still talking about her visit. This was made possible through funding from the GDST and we are very proud to be part of this movement in girls’ education. The highlights in the Junior School are too many to mention, but the new art work and displays throughout the Juniors show the wonderful end products from the numerous col- laborative, creative workshops this term. As always, the girls never cease to amaze me with their confi- dence, talents and determination. This was seen in abundance at our recent Open Events and there were many proud moments on receiving the glow- ing feedback about our girls from the record num- bers of visitors. I hope you enjoy a relaxing half term break and I look forward to welcoming the girls back on the 4th November. Thank you for your continued support. Rebecca Mahony Sophie the T-Rex came to visit!

    Government and Opposition (2021), 56, 615–639 doi:10.1017/gov.2020.4 . ARTICLE Unravelling the New Plebiscitary Democracy: Towards a Research Agenda Frank Hendriks* https://www.cambridge.org/core/terms Tilburg University, Department of Public Law and Governance, Tilburg, the Netherlands *Corresponding author. Email: [email protected] (Received 2 August 2019; revised 25 November 2019; accepted 17 January 2020; first published online 20 March 2020) Abstract Pushed by technological, cultural and related political drivers, a ‘new plebiscitary democ- racy’ is emerging which challenges established electoral democracy as well as variants of deliberative democracy. The new plebiscitary democracy reinvents and radicalizes longer-existing methods (initiative, referendum, recall, primary, petition, poll) with new tools and applications (mostly digital). It comes with a comparatively thin conceptualiza- tion of democracy, invoking the bare notion of a demos whose aggregated will is to steer actors and issues in public governance in a straight majoritarian way. In addition to unrav- , subject to the Cambridge Core terms of use, available at elling the reinvented logic of plebiscitary democracy in conceptual terms, this article fleshes out an empirically informed matrix of emerging formats, distinguishing between votations that are ‘political-leader’ and ‘public-issue’ oriented on the one hand, and ‘inside-out’ and ‘outside-in’ initiated on the other hand. Relatedly, it proposes an agenda for systematic research into the various guises, drivers and implications of the new plebis- citary democracy. Finally, it reflects on possible objections to the argumentation. 28 Sep 2021 at 17:33:14 , on Keywords: new plebiscitary democracy; democratic transformation; electronic voting; digital democracy; populism Vox populi redux 170.106.35.229 In May 2018, the Spanish left-wing political party Podemos organized a digital party referendum, as they called it, on its leadership.

  • “Trainy Mctrainface” – a Possible Comeback for Boaty Mcboatface in Sweden
    2017-07-14 06:00 CEST “Trainy McTrainface” – a possible comeback for Boaty McBoatface in Sweden In 2016 the name Boaty McBoatface won a landslide victory when the British public were invited to provide name suggestions for a polar research ship. Despite the win, the Natural Environment Research Council (NERC) instead decided to name the vessel after Sir David Attenborough. Now Boaty has a possible comeback, as its “cousin” Trainy McTrainface was the most common suggestion when the Swedish private rail operator MTR Express invited the public to provide suggestions to be put to a vote. In May 2017, the newspaper Metro and MTR Express asked Metro’s readers to submit name suggestions for four of MTR Express’ trains. The most frequent proposal by far was “Trainy McTrainface”, a hats off to Boaty McBoatface. The name was the people’s overwhelming choice in an online naming contest organized by the NERC, for a £200 million polar research vessel that attracted global attention last year. However, Science Minister Jo Johnson suggested there were "more suitable" names and the NERC decided to instead name the ship after the world-renowned naturalist and broadcaster, Sir David Attenborough. To partially accommodate the wishes of the public the name Boaty McBoatface was given to a robotic undersea research vessel. Now Boaty McBoatface has a chance to make a comeback as Trainy McTrainface, one of top eight submitted names that the public can now vote for to name an MTR Express train. The vote takes place on Metro’s website and closes on July 17th . MTR-koncernen, med bas i Hongkong, är ett av världens ledande företag inom spårbunden kollektivtrafik och infrastruktur.

  • Production of Teaching Resources for the Polar Explorer Programme
    Invitation to Tender: Production of teaching resources for the Polar Explorer programme Summary Created for schools who are keen to raise aspirations and attainment in science, technology, engineering and mathematics (STEM), the Polar Explorer Programme aims to inspire the next generation of scientists and engineers. https://www.stem.org.uk/welcome-polar-explorer-programme As part of this initiative we are seeking consultants to undertake the development of individual teaching resources directly relevant to the curriculum for students aged 7- 12 in STEM subjects (or computing), which should be focused around at least one of the themes of the Polar Explorer Programme. Consultants may bid for one or more of the following resources: 1 x Transition Project – A resource that can be used with 10-12 year olds as they move from primary to secondary/post-primary. 1 x STEM Career Booklet – Looking at the various careers of those who work on polar vessels as well as at polar research stations, and those involved in the planning and logistics of the trip. 1 x Polar Explorer ‘Cook Book’ – A guide to polar food science including nutrition, recipes, preservation, storage and transport. 1. Background In 2014 the Government announced a £200 million investment for a new polar research ship. The RRS Sir David Attenborough will enable world-leading research in Antarctica and the Arctic for the next 25 years. Fully equipped with the latest instrumentation for the purposes of carrying out research in polar-regions, this vessel will have improved ice strengthened capability and greater endurance over existing polar research vessels.
