Nine sessions to be teleconferenced from Los An­ geles The Symposium on Polymer Characterization by Interdisciplinary Methods will be teleconferenced from the Los Angeles meeting. Sponsored by the Division of Polymeric Materials: Science & Engineering, the five-day program will feature internationally rec­ ognized speakers and will cover air aspects of the topic. If your organization has several scientists who are interested in this timely symposium, but who cannot travel to Los Angeles, a tele­ conference subscription will allow them to participate in the meeting right in your conference room. Subscribing sites will be linked to the Los Angeles symposium by telephone lines that will allow scientists hundreds of miles from the session room to hear presentations and to ask questions and comment during discus­ sion periods. Each location will receive a set of the speakers' slides for viewing during the presentations and abstracts of these papers. Each half-day session will cost $600 per remote location. Teleconferencing has been a regular feature of ACS national meetings for several years and the number of enthusiastic sub­ scribers is growing. If your company would like to learn more about the program, the symposium and/or subscription fees, please contact the Department of Meetings & Divisional Activities at (202) 872-4608.

Los Angeles Employment Aids

An ACS National Employment Clearing House (NECH) will be available to ACS members and student affiliates at the Los Angeles meeting. It will be located in Petree Hall in the Los Angeles Convention Center and will be in operation Monday, Sept. 26, through Thursday, Sept. 29. Candidates are urged to submit completed NECH forms to the national office in advance of the meeting, no later than Sept. 1. To further assist in early registration, NECH will be open Sunday, Sept. 25, from 2 to 7 PM. Records of candidates who register on Sunday and records received in advance of the meeting from candidates who complete registration requirements on Sunday will be on file for employers to review when NECH opens officially Monday, Sept. 26, at 8 AM. In addition to the standard ACS summary form, candidates may submit a one-page résumé. This will be filed separately in the employer area for interested employers to review. Records received in advance will not be placed on file to be reviewed until the candidate reports in Los Angeles and completes final registration requirements. When requesting forms for NÈCH, please specify the Los Angeles meeting as these differ from the year-round forms. At the request of the Joint Subcom-

mittee on Employment Services, a special feature at this meeting will be a section (category) for technicians. For additional information, contact the Employment Services Offices. The meeting registration fee may be waived for an unemployed member to use NECH. For an advance waiver, forward the preregistration form from this issue with your request to the ACS Employment Services Office. At the- meeting, come to the NECH Staff Office in Petree Hall of the Convention Center. Employers' representatives are encouraged to submit forms to D.C. in advance. You may register or check in beginning Sunday, Sept. 25, from 2 to 7 PM. Early registration will allow you to post openings and to have a registration on file so that you may begin reviewing candidates' records and scheduling interviews promptly Monday morning, Sept. 26. Representatives who wish to post an opening may obtain standard forms in advance. A separate form should be submitted for each opening and must be in triplicate. To assure early posting, forms should be returned to the national office no later than Sept. 1. The forms also may be delivered to NECH during the meeting. Openings will be posted just as soon as possible, but because of the volume received on-site, there will be certain delays. All completed forms must comply with all federal regulations on job discrimination in employment or they will not be accepted. Recent users will receive a mailing containing the needed forms. If you have not made use of the service recently, request forms from the ACS Employment Services Office.

NECH employment questionnaires The National Employment Clearing House (NECH) has served ACS members for more than 50 years. During that time many chemists and chemical engineers have found rewarding careers through contacts made at NECH. The Joint Subcommittee on Employment services and the ACS staff are devoted to making NECH even more effective than it has been in the past. Participants can help accomplish this by responding to the surveys that are sent out to both employers and candidates following each ACS national meeting. A typical response is about 60% of those surveyed, but we would like to hear from the rest of you! Please take just a few minutes of your time to help the subcommittee and the ACS staff do a better job for you. If you should have comments, suggestions, or ideas that go beyond the format of the questionnaire, do not hesitate to contact Audra Rafter at ACS headquarters, (202) 872-6208, or subcommittee chairman Bruce Davis, (213) 694-7154.

The "positions available" area will open as early as possible Monday, Sept. 26, so that candidates may review the openings posted. Any member registered for the meeting may review the openings. However, if you are not registered with NECH, it is your responsibility to contact the employer representative by mail. NECH delivers messages for registered candidates only. Employer representatives are also encouraged to submit descriptive material or an annual report on your company. This will be retained on file for interested candidates to review. Request all forms from the ACS Employment Services Office, 1155—16th St., N.W., Washington, D.C. 20036, or call (202) 872-6208.
