I have very much enjoyed the opportunity to serve you as President for the last two years. We have seen some changes that I believe are for the better. I think a quick look at the CSNA homepage (http://www.pitt.edu/~csna/) is enough to convince one that we are certainly in tune with the times. You can see there several things that attest to the quality and quantity of our activity. A look at the Call for Papers for the June meeting in Amherst shows that we are have a fine scientific experience in store for us. Sessions in consensus theory, graph theory, information retrieval, image analysis and reticulate evolution, as well as the keynote speakers Donald German, Bruno Leclerc, Phillipa Pattison, and David Swofford are something to look forward to. A quick scan of the table of contents of the next issue of the Journal of Classification, shows that much interesting research is going on among us. I am proud to be a member of CSNA and honored to have been President.

Of course, being President is easy, if you have people like Stan Wasserman and Dawn Iacobucci doing the hard work of "running the business." I cannot say how important their work is to the success of CSNA, and how much I appreciate having worked with these two. I would also like to congratulate the Editors of our publications for the fine work they do. Buck McMorris of the Newsletter and Fionn Murtagh for the Service have had met serious challenges during the last year in converting to online and computer media. And of course there is the incomparable Phipps Arabie of the Journal, the international scientific community is well aware of the outstanding job he as done as the only editor the Journal has had.

Thank you once again for the privilege of serving you and my congratulations to Pete Bryant as he takes over. I wish him well and am sure that he will enjoy the experience as much as I have.

To members of The Classification Society of North America. I have collected the bios on our candidates (two for the Presidential Office, and four for spots on our Board of Directors. These bios follow. I hope they are useful to you in making your voting decisions later this year. Thank you. Dawn Iacobucci.
PRESIDENTAL CANDIDATES (alphabetically):

Stephen C. Hirtle. Associate Professor and Chair, Department of Information Science, University of Pittsburgh. CSNA member since 1982. Co-chair for CSNA-88 at NYU, and chair of CSNA-93 at Pittsburgh. Session organizer for IFCS-89 at Charlottesville. Referee for Journal of Classification. Member of Psychometric Society and Society for Mathematical Psychology. Research interests: lattice-theoretic models, cluster comparisons, similarity measures, spatial knowledge structures, and applications for cognitive science.

"CSNA has a unique interdisciplinary perspective that needs to be fostered and promoted among related disciplines. I am interested in expanding our relationships to include additional topic areas and in expanding our sphere of influence among classification researchers. We were one of the first organizations of our size with a strong World Wide Web presence, which helps our visibility. As we look toward the next 25 years, it is critical that our annual meetings continue to present a strong scientific program and at the same time facilitate informal discussions. It is through the strength of our scientific meetings and publications that a small society such as ours can continue to prosper."

Stanley Wasserman. Professor of Psychology, Statistics, and Sociology, and Professor, Beckman Institute for Advanced Science and Technology, University of Illinois. Previous appointments at Carnegie-Mellon University, the University of Minnesota, Columbia University, and the University of Melbourne. Academic background includes Ph.D. (Statistics, 1977), Harvard University; M.S. (Business and Applied Economics, 1973) and B.S. (Economics, 1973), University of Pennsylvania. CSNA member since the mid- 1980s, Member of Board of Directors (1991-present), Secretary/Treasurer (1991- 1994), Chair, Finance Committee (1995-present). Plenary lectures given at CSNA90 and CSNA92, special session organizer, CSNA96; proposed host of CSNA98, joint with the Psychometric Society, at the University of Illinois. Editorial board of a number of journals, including the Journal of the American Statistical Association and Psychometrika. Book Review Editor for Chance. Author of Social Network Analysis: Methods and Applications (Cambridge University Press, 1994). Fellow of the American Statistical Association and the American Association for the Advancement of Science. Research interests include statistical models for classification and clustering, especially for networks, and methods of categorical data analysis.

"CSNA is a unique professional society, very interdisciplinary, with a remarkable group of members. This diversity is its strength, and its biggest asset. In the coming years, it will be important to utilize the interdisciplinary aspects of the society, as well as the quality of its members, in order to cut member losses. CSNA has been hurt financially in recent years --- membership has fallen and expenses have had to be cut. Going to electronic versions of the CSNA Bibliographic Service (and perhaps the Newsletter as well) and building our own WWW pages has helped, but more economizing needs to be done. As President, as I did as Business Manager, I will oversee future budgets, and will work hard to increase revenues, through membership drives and continued diversity in presentations at our Annual Meetings (which have always been one of the best parts of CSNA, and good sources of revenue). I will ask you for your help in these tasks, by recommending others for membership and for ideas for future Annual Meetings, especially for joint meetings with "like- minded" societies. I will ask you to work with me to bring others into CSNA (especially students and young researchers) through special topics sessions at our meetings. Better links to the biomedical areas, marketing, and information science would be nice to develop. I could see organizing sessions at annual meetings of other societies (such as the newly formed Mathematical Sociology section of the American Sociological Association, or ORSA/TIMS) ---the American Statistical Association has been quite keen on such special sessions at their annual meetings. The tutorials that we run prior to our own annual meetings could easily be presented to other societies. And lastly, continued growth, expansion, and diversity of our outstanding, flagship journal, the Journal of Classification, can only help publicize and extol CSNA. Overall, I am very proud of CSNA, and will use my time and energy as President to make us more visible, and consequently, help put us on a better financial base."

UPDATE FROM MEL JANOWITZ ABOUT CSNA-NT96:

Here is an update on the current status of the CSNA-NT96 meeting. As you know it will be held at the University of Massachusetts at Amherst, June 13- 16, 1995, and will include the traditional short course on exploratory data analysis. I would encourage anyone planning to present a paper to give some thought to letting the organizers have a title, or a statement of intent, or if possible an abstract. The next issue of the Newsletter will contain a more detailed announcement, together with a copy of the registration form. Incidentally, the registration form should also be available on the CSNA WWW page, or by requesting a copy from one of the organizers.

A number of special sessions are in the planning stages. For the CSNA portion of the meeting, they include: Classification in social network analysis (Stanley Wasserman), General consensus theory (Robert C. Powers), Graduate student session (Peter Bryant), Image analysis and estimation (Sridhar Lakshmanan and Anil Jain), Information retrieval and classification (Stephen C, Hirtle), Pathfinder Networks and proximity graphs (Donald Dearholt).

The NT group has discussed sessions on Biological applications of consensus theory, and Reticulate evolution.

Invited speakers will include: Donald Geman of the University of Massachusetts; Bruno Leclerc of C.A.M.S., Paris; Phillipa Pattison of the University of Melbourne; and D. L. Swofford of the Smithsonian Institution. The after dinner speaker will be Herman Friedman, and his topic will be "Classification and clustering: a perspective on applications".

The organizers of the meeting encourage the presentation of contributed papers that cover a wide range of applications and methodology that involve exploratory data analysis viewed in its broadest sense. Papers related to evolution and molecular biology are of particular interest to the numerical taxonomy group. Short abstracts of papers should be sent to the appropriate program chair, as well as any suggestions for symposia, special sessions, topics, panel discussions, requests for further information, or other contributions. The deadline for submission of abstracts is April 15, 1996 (a familiar date to residents of the U.S.). The program chair for the CSNA program is Melvin F. Janowitz, Department of Mathematics and Statistics, University of Massachusetts, Amherst, MA 01003 USA, telephone (413)-545- 2871, Fax (413)-545-1801, e-mail csna96@math.umass.edu.

* FEB. 28 - MARCH 1, 1996: International Conference on Conceptual Knowledge Processing at the Technische Hochschule Darmstadt, Hauptgebaeude, Hochschulstr. 1, Room 223. This 3-day-conference continues a sequence of meetings which started with the `Arbeitstagung Begriffsanalyse' in January 1986 (see Ganter,Wille, Wolff: Beitrage zur Begriffsanalyse, B.I.- Wissenschaftverlag 1987). The announced international conference follows two meetings on `Begriffliche Wissensverarbeitung' which took place in 1994 and 1995 (see Wille, Zickwolff: Begriffliche Wissensverarbeitung: Grundfragen und Aufgaben, B.I.-Wissenschaftsverlag 1994). These meetings have been stimulated by the foundation of the ErnstSchroederZentrum fur Begriffliche Wissensverarbeitung in which scholars from mathematics, computer, information and social sciences combine to advocate and work for a human- centered development and use of tools and media in information and knowledge processing. The 1996 conference shall continue --- on an international level --- the started exchange and discourse about actual research on conceptual knowledge processing. The conference is organized by the Forschungsgruppe Begriffsanalyse at the Technische Hochschule Darmstadt in cooperation with the ErnstSchroederZentrum and the International Society of Knowledge Organization (ISKO). It is planned to reserve enough time for discussion and exchange of information during the conference. Courses on Formal Concept Analysis will be offered immediately before the conference (February 26-27, 1996) at the TH Darmstadt. Applications should be sent to: Prof. Dr. Rudolf Wille, FB Mathematik, Technische Hochschule, D--64289 Darmstadt, Schlossgartenstrasse 7 (Phone ++49-6151- 163415, Fax ++49-6151-164011, E-mail: ConKnow@mathematik.th- darmstadt.de).
