The second one is essentially the follow-up of Training and mobility of researchers and Infrastructures, with a large scope and hopefully an increased budget. Mathematics will con- tinue to be part of that programme. Here is a description of these two parts, from the point of view of mathematics. The full documents used at the time of writing this summary can be found on the web site of the Commission, http://europa. eu.int/comm/research/nfp. They are the Amended proposal for council decision of January 30, 2002 (241 pages!), the Introduction to the instruments available and Provisions for implementing networks of excel- lence (February 28, 2002). Documents will continue to appear on this site, and may contain modifications with respect to the present description. Finally, a note on vocabulary to avoid confusion. In the Fifth Framework Programmes, mathematics was present under Research networks, or Research train- ing networks: it is still present in FP6 under the name Marie Curie research training net- works. On the other hand, FP6 now has Networks of excellence that are not related to the training networks, and are a new instrument of the research policy.

Integrating and strengthening the ERA This component, with the large budget of 12855 million euros for four years, aims mostly at seven priority themes: 1.1.1. Genomics and biotechnology of health 1.1.2. Information Society technologies 1.1.3.

But to discussion, the idea was rejected, partly because of the difficulty of finding a time that would be convenient for all European Universities, but also because the condi- tions of the job market are so diverse across Europe that it is doubtful whether an EMS meeting could usefully help recruitment. Nonetheless, there is a noticeable stimulus to the Society’s activi- ties at events like the 3ecm, when the Executive Committee, subcommittee chairs and representatives of the national societies can meet. We hope that the Abel conference in Norway in June will give a similar impetus.

EUROPEAN CONGRESS OF MATHEMATICS 2008 Call for Bids for the 5ECM

Outline bids from possible organisers of the 2008 Congress are now invited, and should reach the EMS Secretariat by December 31, 2002. The address of the Secretariat is Mrs Tuulikki Mäkeläinen, Department of Mathematics, University of Helsinki, P.O. Box 4, FI-00014 Helsinki, Finland (Tel: +358-9-1912 2883; Fax: +358-9-1912 3213; Email: [email protected]). The information below may be helpful to possible organisers. Informal discussions are welcomed, and may be addressed to the Secretary (David Brannan; Email: [email protected]) or any other member of the Executive Committee.

General information on ECMs European Congresses of Mathematics are organised every four years: The first Congress was held in Paris in 1992, the second in Budapest in 1996, and the third in Barcelona in 2000. In 2004 the Congress will be held in Stockholm. The next free slot for a Congress is the year 2008. The Congress must be in Europe. Experience of previous Congresses suggests that the attendance might be expected to be around 1000 mathematicians. The dura- tion has so far been 5 days. 10 EMS Prizes to young outstanding European mathematicians are awarded at the opening ceremony. The Congress programme should aimed to present various new aspects of pure and applied mathematics to a wide audience, to offer a forum for discussion of the relationship between mathematics and society in Europe, and to enhance co-operation among mathematicians from all European countries. The standard format of previous ECMs has been: - About 10 Plenary Lectures; - Section Lectures for a more specialized audience, normally several held simultaneously; - Mini-symposia; - Film and mathematical software sessions; - Poster Sessions; - Round Tables. An exhibition space for mathematical societies, booksellers, etc. is required. No official language is specified and no interpreta- tion is needed. Proceedings of the previous ECMs have been published by Birkhäuser Verlag.

Decision process for 5ECM (i) Bids were invited via this notice in the EMS Newsletter in 2001, and via letters to the EMS member societies sent out in 2001 by the EMS Secretariat; the deadline for bids is 31st December 2002. These bids need only be outline bids giving a clear idea of the proposal and possible sources of financial and local support. (ii) Early in 2003 the Executive Committee (‘EC’) of the EMS will consider the bids received. It will invite one or more of the bids to be set out in greater detail so that it can decide which bids are sufficiently serious options to be considered further. The dead- line for such ‘worked up’ bids is 30th June 2003. (iii) The EC will then create a short-list of sites that appear to offer the best possibilities for a successful Congress. (iv) The EC will then appoint a Site Committee to visit the short-listed sites between July and December 2003 to check a range of items in connection with the development of the Congress. For example: - Size and number of auditoriums; location and equipment. - Room for exhibitors. - Hotel rooms and dormitories; location, prices, number in different categories and transportation to lectures. - Restaurants close to Congress site, number and prices. - Accessibility and cost of travel from various parts of Europe. - Financing of the Congress; support to participants from less favoured countries in particular. - Financing for the EMS Prizes. - Experience in organizing large conferences. - Timing of the Congress. - Social events. - Plans to make publicity for Mathematics on the occasion of the Congress. (v) In 2004 the EC will make a recommendation for the site to the EMS Council on the basis of the bid documents and the Site Committee report. The Council will reach its decision prior to 4ECM in 2004.

Relations between the EC and the Organizing Committee of 5ECM After the Council decision, the local organisers will be asked to present a draft budget and an outline of the programme of the Congress. The actual Congress organisation is the responsibility of the local organisers. At least two committees must be appointed, namely the Scientific Committee and the Prize Committee. The Scientific Committee is charged with the responsibility for conceiving the scientific programme and selecting the speakers. The Prize Committee is charged with the responsibility of nominating the EMS Prize-winners. For each of these committees the Chairs are suggested by the local organisers and agreed after consultation with the EC. In turn, the members of the committees are suggested by the Chairs, and are approved after consultation with the EC. The local organisers are responsible for seeking financial support for the Congress and for the meetings of its committees. However the EMS commit to provide some financial support for the travel of Eastern European mathematicians to the ECM, and would also assist and advice in seeking sources of funds, in particular from the EU. The EMS and the local organisers should be partners in the effort to find funding support for the prizes. The level of the registration fees is of great importance to the success of an ECM. The EC asks that it should be involved before a final decision on the level of fees is made; members of the EMS normally receive a reduction of some 20% on the registration fees. The EC would wish to be informed of progress at its regular meetings. The EC would be pleased to offer advice to the local organ- isers on matters such as the scientific programme, budgetary developments, registration, accommodation, publications, web site, etc. Publicity for the ECM via the EMS Newsletter and the EMIS site is strongly recommended.

EMS June 2002 11 FEATURE seems that there is a slight gender dif- ference in interest for application of mathematics to economics (women more interest) or to the natural and technical sciences (men more interest).

The number of women and men obtaining a doctoral degree has remained similar. In the historical sample, 104 women (22.5%) and 676 men (26.2%) were awarded a PhD. Of these, one-third passed the doctoral examination with mathematics as major, and two-thirds with other majors. Men often chose physics as a non-mathematical major, while women chose biology and philoso- phy as often as physics (see Figure 1). Regarding publications after the PhD, there were only small gender differ- ences. The record cards of 12 women (2.6%) and 121 men (4.7%) recorded such work. Of course, participants of our modern sample may not yet have passed their PhD exams yet. We therefore asked them whether they intended to pass a doctoral exam. They indicated their Fig 1 intention on a 5-point likelihood scale ranging from ‘not at all’ to ‘certain’. one to four minors as well. Usually, they try and the private sector.

In the historical sample there was a great gen- der difference in the choice of ‘applied mathematics’, introduced in 1898 (3% women, 21% men), but this may be due to the fact that women at that time had almost no chance of pursuing a career and earning money in areas outside the educational system. In 1898 mathemat- ics included representative geometry, technical mechanics and geodesy (com- bined with probability). The range of choice of mandatory subjects was extended in the following two decades to include astronomy, insurance and finance mathematics, statistics, hydro- dynamics and aerodynamics [10].

Caraça was a gifted speaker. He con- tributed to newspapers and magazines and promoted relevant cultural events in Portugal, artistic meetings, scientific con- ferences and courses, with the main pur- pose of promoting people’s culture. Most of these events took place at the Universidade Popular Portuguesa, an insti- tution where progressive intellectuality and enlightened members of the working classes could discuss cultural and scientific topics. Bento Caraça was president of Universidade Popular for many years, and his activity here was very emblematic, focused on the culturalisation of people and on the defence of democratic values. Another remarkable responsibility was the Biblioteca Cosmos, one of the most signifi- cant cultural achievements of the twentieth century in Portugal. Under Caraça’s lead- ership Cosmos published over 114 titles cov- ering different fields of knowledge in about eight years. He introduced methods of Econometrics in Portugal. In 1938, he founded Centro de Estudos de Matemática Aplicados à Economia, of which he was chair- man. In 1940 he founded the Sociedade Portuguesa de Matemática, of which he was president for two years (1942-44), and founded and edited the journal Gazeta de Matemática. In 1946, Caraça was expelled from his university teaching position. He was perse- cuted by the political police under the dic- tatorship and imprisoned at Aljube. There were many cases of political persecution, and victims included university teachers – in particular, mathematicians. Bento Caraça died on 25 June 1948. Crowds of people of all social classes joined together in the streets of Lisbon in a spontaneous tribute to the Master and to the citizen. Caraça was a man of culture devoted to the pursuit of knowledge, and a talented teacher. In his classes he had a singular style, his fascinating way of presenting sub- jects was so rare that he was seen in the academic community as an idol. He was a pioneer of Portuguese organisations for peace and international movements Bento de Jesus Caraça was born in Vila For the first time, mathematics has been present- against World War II.

Moreover, although being a committee of the EMS, the CDC turns not only to European colleagues, but takes this oppor- tunity to call upon colleagues in any devel- oped country, to join us in our efforts. We are looking mainly for scientific literature published in English or French. As experience has shown, the problem is not to find books for donations to such universities, nor the identification of uni- versities in DCs that are interested in receiving such donations. The problem lies in the shipping expenses and in the logistics. With some cooperation by the various players in this (truly international) action, the CDC will be in a position to ful- fil this task. The CDC hopes to liaise with the International Centre for Theoretical Physics (ICTP) at Trieste, Italy, to organise a book donation scheme. We shall try to identify recipients for donated books and journals. We know, for example, that the University of Zimbabwe not only would gladly accept such donations (it has done so in the past in a different framework), but is also prepared to act as a centre for distribution of donated books to universi- ties in the SADC region, which comprises member states as diverse as South Africa, Zambia, Malawi, Tanzania, Angola and Mozambique. In order to take care of the shipping of donations to the respective places, CDC will apply to the Book Donation Scheme which the ICTP runs, to pay for the trans- port subject to their regulations. We, or the donors, might also try various National Commissions for UNESCO to help with shipping costs. A minimum of 40-50 books constitutes a reasonable consignment. We hope that some of you will not only give away some of your own books, but will also involve yourselves actively in collecting books/journals from other colleagues in your respective departments.

With the growing availability of mathemat- ical articles in electronic form, Zentralblatt MATH was able to extend its services to an important new field of activities, the link- ing to offers of full texts. As a result, addi- tion to the traditional comprehensive sur- vey on the literature in mathematics pro- vided by Zentralblatt, the search facilities in the electronic version are combining the final information on a document of inter- est with an access to the document itself. This access may be activated with a sys- tematic literature retrieval in the Zentralblatt MATH database or just by using this database through the citation and ref- erence checker like a catalogue to find a location, where the document of interest is available. In both cases the user will find two buttons within the full display of the database entry, one linking to the com- plete electronic version of the document if available, and the other linking to a set of document delivery services. The link to the complete electronic ver- sion refers to the service of a publisher, a freely available offer of articles as in the ELibM of EMIS, or just to the installation of the journal on its own homepage. Links are updated when URLs of the offers change. Access to the complete version of the article depends on the regulations made by the provider. Hence, in order to get a copy of an article from a charged electronic version of a journal, a subscrip- tion to this journal will be requested from the user’s side. The link to the set of document delivery services at first gives a list of providers. For example, one of them is the State and University Library of Lower Saxony in Göttingen, which has one of the most com- prehensive collections of publications in mathematics. Having chosen a document delivery service of the user’s preference, the data of the corresponding publication will be exported to the provider’s OPAC, and if the document will be available there, an order form will appear automatically. The requested item will be sent to the user by e-mail, fax or postal mail, depending on how it is stored in the library’s holdings and in accordance with the regulations at the provider. The choice of the document delivery ser- vice by the user is mainly motivated by the delivery conditions, which strongly depend on the location of the user. The search software of Zentralblatt MATH allows for connecting a variety of such services. It is therefore easy to add further providers leading to a system of document delivery services that offers access to complete arti- cles at the most convenient conditions for the user. This development is in progress. 28 EMS June 2002 RECENT BOOKS many recent articles.
