MicroNews

accessible to his readers and listeners. He has been a tireless educator, and a large fraction of active microscopists/microanalysts have learned their skills from him.

The 1994 K. F. J. Heinrich Young Scientist Award is given to Dr. Joseph R. Michael, a member of the research staff of the Sandia National Laboratory. Joe has made significant contributions to the field of analytical electron microscopy, especially regarding issues of the limits of spatial resolution, probe size measurement, quantitative analysis, limits of detection, and the use of massively parallel computing to support basic AEM studies. He has also contributed to the field of scanning electron microscopy, where he has developed techniques to measure solid specimen crystallography by electron backscatter patterns. In addition to his work to advance analytical methodologies, he has made important applications of the techniques to problems in materials science, including grain boundary segregation and diffusion.

The 1994 MAS Presidential Service Award is given to Dr. Jack Worrall, Director of Operations for the Center of Electron Microscopy and Microanalysis at the University of Southern California. Jack has served MAS for several years as our chairperson of the Sustaining Members Committee. A few years ago Jack resigned this position to take on the job/career as local arrangements chair for the 1993 Los Angeles meeting. The overall success of the 1993 meeting was due in large part to Jack's efforts in coordinating the many complex aspects of the meeting. The social arrangements for the meeting were outstanding, beginning with the Peruvian folk ensemble, INCA, and concluding with the trip to Knott's Berry Farm. For the attendees, Jack served as our "beacon in the night" always outwardly calm and smiling even in the midst of the storm. If this was not enough, Jack has agreed to serve MAS once more as chairperson of the Sustaining Members Committee.

In looking back on the first half of my tenure as your president, I would like to say that I am particularly impressed with the core of dedicated volunteers who make MAS unique among the professional societies. These individuals donate their time, talent, and often their own resources to our society. It is primarily through their efforts that MAS maintains a sound financial base and is able to provide its members with a broad range of programs centered around scientific excellence in microbeam analysis.

John A. Small, President

PRESIDENT'S MESSAGE

Dear Members,

The 1994 Winter Council Meeting was held in Boston the second weekend of January. I would like to take this opportunity to officially welcome our new council Directors Paul Hlava and Carol Swyt and to thank our two outgoing directors Phil Russell and John Porter. I would also like to welcome Dave Simons back as our Secretary.

During the meeting, council decided on several issues of interest to our membership. The following three, I felt were of particular importance.

1) Council accepted a proposal by Scott Wight (one of our members from the D.C. area) to establish an 800 number and a P.O. Box to answer questions and provide information related to MAS membership and membership lists. The phone will be answered by phone mail and Scott has agreed to return all calls within one day. The full address and number are listed on the first page of the journal.

2) Council voted to accept a document "Issues for Speaker Support" that was prepared by J. Porter, J. Batstone, and J. Friel. This document provides a framework for the distribution of program funds at MAS meetings.

3) Council established a long-range planning committee that will be addressing, among other things, our relationship with MSA and the structure of our joint meetings.

In addition to the business agenda, I had the privilege of presenting to council my selections for the 1994 Presidential Awards. The 1994 MAS Presidential Award for Outstanding Scientific Contributions is given to Prof. David C. Joy, Director of the Electron Microscope Facility at the University of Tennessee (Knoxville). For the last 25 years, David has made contributions to all aspects of our field, from microscopy to microanalysis, that are distinguished both by their extraordinary numbers and their quality. His work spans the gamut from the basic physics of microscopy/microanalysis (e.g., stopping power measurements, Monte Carlo simulations), to the development of instrumentation (electron energy loss spectrometers), to microanalysis procedures (e. g., EDS and EELS in analytical electron microscopy), to the application of these methods to specific problems in the physical and biological sciences. Most importantly, David has striven to present his research in papers and talks that are lucid and readily

MOUSIN' AROUND

New Network Newsgroups.

On the tail of the last Mousin' Around, which covered The Microscopy Mailing List, the news for this issue is The News. The News I am referring to is Usenet News. Some of you may be asking: "What is Usenet News?" Well, for those of you who are unfamiliar with it, Usenet News is essentially an electronic conferencing/discussion network. News messages are passed around the network from one computer system to another. Many of these systems are on the Internet, but many are not. The Usenet network extends further than the physical network of the Internet. There are many computers that participate in Usenet News that are connected by dial-up modem connections. It is not necessary to have an Internet connection to have access to Usenet.

Usenet is not a new system, it has been in place for many years. In contrast to email, Usenet News is not distributed to an individuals account, but rather to a server at a particular institution (be it a government lab, university or private company) that can then be accessed by individuals who are at that institution (or are permitted to dial in). On Usenet, messages are posted to newsgroups that are designed to cover a particular topic. There are a number of rather general subject categories into which the newsgroups are divided, e.g. comp for computer, rec for recreational and sci for scientific. The newsgroups within each subject category cover a wide variety of fields and serve as forums for questions and answers and general informational postings. There are many hundreds of worldwide newsgroups, i.e. groups that are distributed around the world, and then there also are groups that are only distributed locally. Examples of specific newsgroups are rec.windsurfing, comp.sys.mac.digest (an Apple Macintosh question and answer digest), sci.physics (a physicists forum).

What makes Usenet News worth mentioning here is that there are five new newsgroups in the sci hierarchy that may be of considerable interest to MAS members. These are sci.techniques.microscopy, sci.techniques.xtallography, sci.techniques.spectroscopy, sci.materials and sci.polymers. Since their inception in the latter part of 1993, these newsgroups have rapidly become excellent places to ask questions, post answers, discuss problems, announce conferences, post journal abstracts listings and post vacant positions. Society news and information will also be posted to sci.techniques.microscopy and so MAS members are encouraged to read this newsgroup and join in the discussions and information exchanges.

Postings to each newsgroup are stored on the institution's local NNTP (sorry guys I don't what this acronym is short for, unless it is Network News Transport Protocol!) server and distributed to other sites. So, if you want to use Usenet News you need access to an NNTP server and news reading/posting software to run on your local computer, workstation or terminal. You should contact your local network administrator and ask them if you have access to a Usenet feed and which net-news software they recommend for the machine you use. If they do not have access, ask them why not! The functionality of each news program is best explained by a local expert. I cannot possibly go into all of the details of even one news program here. Suffice it to say, however, if you have access to a news posting and reading program and access to the accompanying NNTP server, you can post articles, questions and information to be read by people around the world.

Some questions remain: Why News and not just Email? After all, we have the Microscopy Mailing List, so why not just email the messages to interested parties? Well, this assumes that the addresses of all the interested parties are known. Mailing lists are a common way of maintaining a discussion group and the main advantage of News over email mailing lists is the messages reside on a remote machine and do not fill up your mailbox. Some people have severely restricted mailbox size allocations and the output from a mailing list can swamp them and prevent them from receiving other mail. With Usenet you only download the News you want to read. You can subscribe to a small subset of the total newsgroups and selectively scan through those. You may view all of the subjects of the articles in a group before you read any of them.

For those of you who have a strong preference for email or Usenet and would like to use just one of them, the author and Nestor Zaluzec (who maintains the Microscopy Mailing List) are working on a modification of the list that will forward each message posted to it to Usenet and take messages posted to Usenet News and forward them to the mailing list. This modification should be in place by the middle of this year. Until then, the author will forward conference and course information and journal abstract postings between the two systems. If you have questions about sci.techniques.microscopy, send email to John.F.Mansfield@umich.edu.

Sidebar

I can't get to the Internet, what do I do?

The one major complaint about Net News is that it is not accessible unless you have a connection to the Internet. This is not true. Some of the dial-up bulletin board systems have Usenet feeds. You should check with your local computer users group to find out how you can get access to Usenet. You might find it most cost effective and flexible to pay for a dial-up Internet connection. A connection used to be an expensive proposition, however, these days it can be as reasonably priced as Compuserve or the other dial-up network services. For example, "The World" (1-617-739-0202) charges $20 per month for 20 hours of connect time to Internet services. Another provider "The WELL" (Whole Earth 'Lectronic Link - 1-415-332-4335) charges $15 per month and $2 per hour for use. For a local provider please call the InterNIC Information Services at 1-800-444-4345.

MAS TOUR SPEAKER PROGRAM

So far, I have had very little response from the Affiliated Societies to my letter of September 1, 1993 and the announcements in Microbeam Analysis. I am asking the rest of the societies to contact me as soon as possible, even if they don't plan to host a tour speaker. I need to know from those Affiliated Societies who plan to host a speaker, which tour speaker they desire and when. As soon as I get enough societies to respond I will be able to arrange Tour Speaker trips. The three or four I've heard from just isn't enough. Below is listed the slate of Tour Speakers available, with their affiliations and the titles of their talks. It would be nice if the contact people would call and tell me that they are planning a meeting on XX and the date and speaker will be chosen then.

	MicroNews	accessible to his readers and listeners. He has been a tireless educator, and a large fraction of active microscopists/microanalysts have learned their skills from him. The 1994 K. F. J. Heinrich Young Scientist Award is given to Dr. Joseph R. Michael, a member of the research staff of the Sandia National Laboratory. Joe has made significant contributions to the field of analytical electron microscopy, especially regarding issues of the limits of spatial resolution, probe size measurement, quantitative analysis, limits of detection, and the use of massively parallel computing to support basic AEM studies. He has also contributed to the field of scanning electron microscopy, where he has developed techniques to measure solid specimen crystallography by electron backscatter patterns. In addition to his work to advance analytical methodologies, he has made important applications of the techniques to problems in materials science, including grain boundary segregation and diffusion. The 1994 MAS Presidential Service Award is given to Dr. Jack Worrall, Director of Operations for the Center of Electron Microscopy and Microanalysis at the University of Southern California. Jack has served MAS for several years as our chairperson of the Sustaining Members Committee. A few years ago Jack resigned this position to take on the job/career as local arrangements chair for the 1993 Los Angeles meeting. The overall success of the 1993 meeting was due in large part to Jack's efforts in coordinating the many complex aspects of the meeting. The social arrangements for the meeting were outstanding, beginning with the Peruvian folk ensemble, INCA, and concluding with the trip to Knott's Berry Farm. For the attendees, Jack served as our "beacon in the night" always outwardly calm and smiling even in the midst of the storm. If this was not enough, Jack has agreed to serve MAS once more as chairperson of the Sustaining Members Committee. In looking back on the first half of my tenure as your president, I would like to say that I am particularly impressed with the core of dedicated volunteers who make MAS unique among the professional societies. These individuals donate their time, talent, and often their own resources to our society. It is primarily through their efforts that MAS maintains a sound financial base and is able to provide its members with a broad range of programs centered around scientific excellence in microbeam analysis. John A. Small, President

PRESIDENT'S MESSAGE Dear Members, The 1994 Winter Council Meeting was held in Boston the second weekend of January. I would like to take this opportunity to officially welcome our new council Directors Paul Hlava and Carol Swyt and to thank our two outgoing directors Phil Russell and John Porter. I would also like to welcome Dave Simons back as our Secretary. During the meeting, council decided on several issues of interest to our membership. The following three, I felt were of particular importance. 1) Council accepted a proposal by Scott Wight (one of our members from the D.C. area) to establish an 800 number and a P.O. Box to answer questions and provide information related to MAS membership and membership lists. The phone will be answered by phone mail and Scott has agreed to return all calls within one day. The full address and number are listed on the first page of the journal. 2) Council voted to accept a document "Issues for Speaker Support" that was prepared by J. Porter, J. Batstone, and J. Friel. This document provides a framework for the distribution of program funds at MAS meetings. 3) Council established a long-range planning committee that will be addressing, among other things, our relationship with MSA and the structure of our joint meetings. In addition to the business agenda, I had the privilege of presenting to council my selections for the 1994 Presidential Awards. The 1994 MAS Presidential Award for Outstanding Scientific Contributions is given to Prof. David C. Joy, Director of the Electron Microscope Facility at the University of Tennessee (Knoxville). For the last 25 years, David has made contributions to all aspects of our field, from microscopy to microanalysis, that are distinguished both by their extraordinary numbers and their quality. His work spans the gamut from the basic physics of microscopy/microanalysis (e.g., stopping power measurements, Monte Carlo simulations), to the development of instrumentation (electron energy loss spectrometers), to microanalysis procedures (e. g., EDS and EELS in analytical electron microscopy), to the application of these methods to specific problems in the physical and biological sciences. Most importantly, David has striven to present his research in papers and talks that are lucid and readily



	MOUSIN' AROUND New Network Newsgroups. On the tail of the last Mousin' Around, which covered The Microscopy Mailing List, the news for this issue is The News. The News I am referring to is Usenet News. Some of you may be asking: "What is Usenet News?" Well, for those of you who are unfamiliar with it, Usenet News is essentially an electronic conferencing/discussion network. News messages are passed around the network from one computer system to another. Many of these systems are on the Internet, but many are not. The Usenet network extends further than the physical network of the Internet. There are many computers that participate in Usenet News that are connected by dial-up modem connections. It is not necessary to have an Internet connection to have access to Usenet. Usenet is not a new system, it has been in place for many years. In contrast to email, Usenet News is not distributed to an individuals account, but rather to a server at a particular institution (be it a government lab, university or private company) that can then be accessed by individuals who are at that institution (or are permitted to dial in). On Usenet, messages are posted to newsgroups that are designed to cover a particular topic. There are a number of rather general subject categories into which the newsgroups are divided, e.g. comp for computer, rec for recreational and sci for scientific. The newsgroups within each subject category cover a wide variety of fields and serve as forums for questions and answers and general informational postings. There are many hundreds of worldwide newsgroups, i.e. groups that are distributed around the world, and then there also are groups that are only distributed locally. Examples of specific newsgroups are rec.windsurfing, comp.sys.mac.digest (an Apple Macintosh question and answer digest), sci.physics (a physicists forum). What makes Usenet News worth mentioning here is that there are five new newsgroups in the sci hierarchy that may be of considerable interest to MAS members. These are sci.techniques.microscopy, sci.techniques.xtallography, sci.techniques.spectroscopy, sci.materials and sci.polymers. Since their inception in the latter part of 1993, these newsgroups have rapidly become excellent places to ask questions, post answers, discuss problems, announce conferences, post journal abstracts listings and post vacant positions. Society news and information will also be posted to sci.techniques.microscopy and so MAS members are encouraged to read this newsgroup and join in the discussions and information exchanges. Postings to each newsgroup are stored on the institution's local NNTP (sorry guys I don't what this acronym is short for, unless it is Network News Transport Protocol!) server and distributed to other sites. So, if you want to use Usenet News you need access to an NNTP server and news reading/posting software to run on your local computer, workstation or terminal. You should contact your local network administrator and ask them if you have access to a Usenet feed and which net-news software they recommend for the machine you use. If they do not have access, ask them why not! The functionality of each news program is best explained by a local expert. I cannot possibly go into all of the details of even one news program here. Suffice it to say, however, if you have access to a news posting and reading program and access to the accompanying NNTP server, you can post articles, questions and information to be read by people around the world. Some questions remain: Why News and not just Email? After all, we have the Microscopy Mailing List, so why not just email the messages to interested parties? Well, this assumes that the addresses of all the interested parties are known. Mailing lists are a common way of maintaining a discussion group and the main advantage of News over email mailing lists is the messages reside on a remote machine and do not fill up your mailbox. Some people have severely restricted mailbox size allocations and the output from a mailing list can swamp them and prevent them from receiving other mail. With Usenet you only download the News you want to read. You can subscribe to a small subset of the total newsgroups and selectively scan through those. You may view all of the subjects of the articles in a group before you read any of them.		For those of you who have a strong preference for email or Usenet and would like to use just one of them, the author and Nestor Zaluzec (who maintains the Microscopy Mailing List) are working on a modification of the list that will forward each message posted to it to Usenet and take messages posted to Usenet News and forward them to the mailing list. This modification should be in place by the middle of this year. Until then, the author will forward conference and course information and journal abstract postings between the two systems. If you have questions about sci.techniques.microscopy, send email to John.F.Mansfield@umich.edu. Sidebar I can't get to the Internet, what do I do? The one major complaint about Net News is that it is not accessible unless you have a connection to the Internet. This is not true. Some of the dial-up bulletin board systems have Usenet feeds. You should check with your local computer users group to find out how you can get access to Usenet. You might find it most cost effective and flexible to pay for a dial-up Internet connection. A connection used to be an expensive proposition, however, these days it can be as reasonably priced as Compuserve or the other dial-up network services. For example, "The World" (1-617-739-0202) charges $20 per month for 20 hours of connect time to Internet services. Another provider "The WELL" (Whole Earth 'Lectronic Link - 1-415-332-4335) charges $15 per month and $2 per hour for use. For a local provider please call the InterNIC Information Services at 1-800-444-4345. MAS TOUR SPEAKER PROGRAM So far, I have had very little response from the Affiliated Societies to my letter of September 1, 1993 and the announcements in Microbeam Analysis. I am asking the rest of the societies to contact me as soon as possible, even if they don't plan to host a tour speaker. I need to know from those Affiliated Societies who plan to host a speaker, which tour speaker they desire and when. As soon as I get enough societies to respond I will be able to arrange Tour Speaker trips. The three or four I've heard from just isn't enough. Below is listed the slate of Tour Speakers available, with their affiliations and the titles of their talks. It would be nice if the contact people would call and tell me that they are planning a meeting on XX and the date and speaker will be chosen then.
