Update on Ifremer technological developments and operational feedbacks with underwater systems
This paper reports on the status of Ifremer Underwater systems. It will focus on recent innovations, improvements and operational references of the remotely operated vehicle “Victor 6000”, of the autonomous underwater vehicles “AsterX” and “IdefX”, of the new “Sysif” seismic tool and some hints about RanD in the domain of Advanced Intervention AUVs.
First Steps in Ifremer s Autonomous Underwater Vehicle ProgramA 3000
This paper presents the new Autonomous Underwater Vehicle Program launched by the French Institute for the Sustainable Exploitation of the Sea (Ifremer), for new programs related to environmental survey and monitoring. For several years Ifremer has been involved in technological development of intervention AUVs in collaboration with industrial partners. Historically, Ifremer was also a pioneer of underwater vehicles with the deep sea AUV, Epaulard in the 80s (Michel et al. 84). The first step in the new Coastal AUV program is the development of a 3000m depth survey AUV, described in this paper and built by International Submarine Engineering, in partnership with French partners such as Cybernetix.
Randi Weingarten, the American Federation of Teachers, and the Challenges of Policy Leadership in a Hostile Environment
Randi Weingarten is the president of the most vocal and influential teachers’ union, the American Federation of Teachers. Since rising through the ranks to AFT president in just two years, Weingarten is now a major, if not the most prominent, nongovernmental player in national education policy. She has earned deep respect from many educational policy actors. Likewise, Weingarten elicits withering criticism from others. This fascinating profile explains why, in such a brief period, she has proved to be a fierce, fearless, and effective leader under extraordinarily difficult circumstances. Her experience offers invaluable lessons applicable for others working in similarly intense policy arenas.
