  • Mothers in Science
    The aim of this book is to illustrate, graphically, that it is perfectly possible to combine a successful and fulfilling career in research science with motherhood, and that there are no rules about how to do this. On each page you will find a timeline showing on one side, the career path of a research group leader in academic science, and on the other side, important events in her family life. Each contributor has also provided a brief text about their research and about how they have combined their career and family commitments. This project was funded by a Rosalind Franklin Award from the Royal Society 1 Foreword It is well known that women are under-represented in careers in These rules are part of a much wider mythology among scientists of science. In academia, considerable attention has been focused on the both genders at the PhD and post-doctoral stages in their careers. paucity of women at lecturer level, and the even more lamentable The myths bubble up from the combination of two aspects of the state of affairs at more senior levels. The academic career path has academic science environment. First, a quick look at the numbers a long apprenticeship. Typically there is an undergraduate degree, immediately shows that there are far fewer lectureship positions followed by a PhD, then some post-doctoral research contracts and than qualified candidates to fill them. Second, the mentors of early research fellowships, and then finally a more stable lectureship or career researchers are academic scientists who have successfully permanent research leader position, with promotion on up the made the transition to lectureships and beyond.

  • Oxfordcolleges
    Oxford colleges Oxford University is made up of different colleges. Colleges are academic communities. They are where students usually have their tutorials. Each one has its own dining hall, bar, common room and library, and lots of college groups and societies. If you study here you will be a member of a college, and probably have your tutorials in that college. You will also be a member of the wider University, with access to University and department facilities like laboratories and libraries, as well as hundreds of University groups and societies. You would usually have your lectures and any lab work in your department, with other students from across the University. There is something to be said for an academic atmosphere wherein everyone you meet is both passionate about what they are studying and phenomenally clever to boot. Ziad 144| Does it matter which college I go to? What is a JCR? No. Colleges have a lot more in common than Junior Common Room, or JCR, means two they have differences.

  • EUROPEAN WOMEN in MATHEMATICS Newsletter 16
    EUROPEAN WOMEN IN MATHEMATICS Newsletter 16 Edited by Sara Munday and Elena Resmerita 2010/1 Letter from the New Convenor Dear EWM members, I would like to start by saying how moved I was to be asked to be involved again with EWM activities, when Frances Kirwan wrote to me last summer, inviting me to consider becoming the next EWM convenor. I was among the founding members of EWM in 1986 in Paris, a few weeks after being in Berkeley where AWM organized a panel session I participated in as the French representative, at the invitation of Lenore Blum. The French association femmes & maths was also created in the same period, and I was its first president. Since then I have participated in several EWM general meetings: Paris, Marseille, Warsaw, Madrid, Loccum, Malta. The talk I gave in Loccum in the session on Hilbert Marie-Françoise Roy problems was closely related to the paper I wrote in the volume Mathematics unlimited, 2001 and Beyond « Three problems in real algebraic geometry and their descendants ». Mathematically speaking, I am a specialist in real algebraic geometry, and most recently, its algorithmic part. Algorithms in real algebraic geometry form a fascinating topic related to algebra, geometry, topology, logic, theoretical and practical commuter science, and a variety of applications. How can we decide efficiently whether two points belong to the same connected component of a set defined by a boolean combination of polynomial inequalities? This question is closely related to the «Piano mover's problem» in robotics! Most of my papers are coauthored, and I enjoy collaborative work, as well as acting as advisor for research students.

This document lists the membership of the main and sub-panels for the 2008 Research Assessment Exercise (RAE2008). The panels will assess the quality of research in submissions to RAE2008. Key points 2. For the purpose of RAE2008, each academic discipline is assigned to one of 67 units of assessment (UOAs). There is a two-tier panel system: 67 sub-panels of experts, one for each UOA, work under the guidance of 15 main panels. Under each main panel are broadly cognate disciplines whose subjects have similar approaches to research. 3. Panel members are experts drawn from higher education institutions (HEIs) and the wider research community, and are nominated by subject associations and other stakeholder organisations. Each main panel and sub-panel has stipulated criteria and working methods that they will adhere to in making assessments: these were published in January 2006 as RAE 01/2006: RAE2008: Panel criteria and working methods. 4. This list of panel membership is correct at the time of going to print. Should any member retire from the panel or be replaced during 2008, we will update the electronic list available at www.rae.ac.uk under ‘Panels’.

Coming to a birthday party, one is aware that not all the birthdays are the same. Some have a human dimension, some go far beyond. One hundred and fifty would be fit for a rather healthy elephant, or maybe a mighty whale. Of course, it is not the age itself which matters, rather the wisdom which comes with it. In the case of the London Mathematical Society it raises no doubts. It had not only a brilliant childhood and youth – there is no need to go to detail after we have listened to the talk of Frances Kirwan – but it Pavel Exner, President of the European Mathematical Society and remains equally strong nowadays, and I dare Terry Lyons, President of the London Mathematica Society to say that it reached the stage of mature wisdom which your friends across the water respect, from outside of this island brings me naturally to the enjoy, and admire.
