         The Journal of Symbolic Computation
  -----------------------------------
  [Editor-in-Chief: Bruno Buchberger]

     Special Issue on Executable Temporal Logics
      Guest Editors: Michael Fisher, Shinji Kono, Mehmet Orgun

   Call For Papers
   ---------------

BACKGROUND: Logical representations have been widely used in Computer
Science and Artificial Intelligence. In recent years, particularly
with the advent of languages such as Prolog, the direct execution of
such representations has been shown to be both feasible and useful.
Logic-based languages have been used, not only for applications such
as the animation of logical specifications, the characterisation of
database queries and knowledge representation, but also as high-level
programming languages in their own right. However, as the problems
tackled have become more complex, the requirement for more powerful
logical representations has been growing. In particular, since the
concept of time is of central importance to an increasingly wide range
of applications, including the representation of time-dependent data
and the specification and verification of concurrent and distributed
systems, many logics incorporating temporal notions are being
developed and applied.

It is not surprising, therefore, that executable temporal logics have
been proposed in order to provide system developers with access to
these, more powerful, logical techniques. Just as the development of
sophisticated, and relatively efficient, theorem-proving techniques
for first-order logic led to executable forms, such as Prolog, so the
development of executable methods for temporal logics has often been
based on temporal theorem-proving techniques. However, each particular
executable temporal logic combines not only a logical perspective, but
also an operational model, drawn from its intended application areas.
Thus a wide range of languages have appeared, exhibiting a variety of
characteristics and execution mechanisms. Consequently, such languages
have a variety of application areas, such as temporal databases,
temporal planning, animation of temporal specifications, hardware
simulation, and distributed AI.

OBJECTIVES: The Journal of Symbolic Computation is planning a special
issue on Executable Temporal Logics, scheduled to appear in 1996.
High quality original research papers are solicited on all aspects
relating to the foundations, implementation techniques and
applications of languages based upon temporal logic. The research
described must not only incorporate an adequate level of technical
detail, but must also provide a clear indication of both the utility
and the applicability of the results. 

Topics of interest include, but are not limited to,

   * theoretical issues in executable temporal logics
   * design of executable temporal logics
   * relationship between execution and temporal theorem-proving
   * operational models and implementation techniques
   * programming support and environments
   * comparative studies of languages
   * relationship of executable temporal logics to (temporal) databases  
   * applications and case studies

Because of the nature of the journal, it is particularly important
that submissions, even purely theoretical ones, indicate the
algorithmic relevance and applicability of the approach.

Papers must be original and must not have been previously published or
simultaneously submitted for publication elsewhere. The papers will be
reviewed based on their originality and technical quality, relevance
to the special issue theme, and the extent to which they will advance
the frontiers of knowledge in this area.

In addition to longer papers, we would welcome short papers (5 to 10
pages) describing specific features or novel applications of
executable temporal logic.

Submissions should follow the JSC style guide available from

 ftp://ftp.risc.uni-linz.ac.at/pub/jsc

LaTeX users are encouraged to use the jsc.sty file.

Electronic submission is strongly encouraged (either as self-contained
LaTeX, or postscript). Submissions, either electronic or a paper copy

IN OR OUT? THE AREA CODE PLAN: AMERITECH MAPS PROPOSED 312 / 773 SPLIT
By MARK VEVERKA

Ameritech Illinois has unveiled its much-anticipated boundary proposal
for two area code zones in Chicago.  The shrunken 312 area code in the
city center would be larger than originally announced -- peaking north
of Armitage Avenue and extending to 35th Street on the south, Western
Avenue on the west and the lakefront on the east.  Everywhere else
within the city limits would be in a new 773 area code.  The plan must
be approved by the Illinois Commerce Commission, which also is
considering an alternative that would create an "overlay" area code
for all new users in the existing 312 geographic area.  Although
Ameritech prefers an overlay, it has agreed with other 
telecommunications 
companies to support a dual geographic zone configuration. But because
of technological limitations, boundaries for such a configuration
would not follow straight lines, such as streets.  "That means you
have a jagged (border) that corresponds to no known geography" says
Martin Cohen, executive director of the Citizens Utility Board (CUB).
"The way the lines will run will be very confusing to those who are on
the borders."  Despite some of the plan's imperfections, Mr. Cohen's
utility watchdog group endorsed Ameritech's dual area code solution.
Originally, CUB argued that an outer ring should get the 312
designation -- because the area has more residential users, who are
the organization's primary constituency.

However, 70% of the city's businesses are in the core zone, and
preserving 312 for Chicago's commercial center, including the Loop, is
at the heart of the phone company's plan.  "Businesses incur a lot of
out-of-pocket expenses when an area code gets changed," says an
Ameritech Illinois spokeswoman.

The 773 area code would go into effect in October 1996.  "It will be
an inconvenience at first that will cost us some money to change some
forms -- but eventually, everybody will get used to it," says Steve
Larrick, chief executive of Chicago-based Chernin's Shoes, whose North
Halsted Street store would be just north of the 312 border in the 773
area.  The phone company says the area code reconfiguration should
prevent a numbers shortage beyond 2000 -- but it gave the same
assurances when it implemented the 708 area code in 1989.  "The
thinking was that (708) would last until the next century. It did
not," the Ameritech spokeswoman says.

------------------------------



I was just looking through some of Steve Grandi's notes about upcoming
area code splits and overlays, and something caught my attention,
specifically in regard to the Chicago area.

The original plan was that 630 would be implemented as an overlay of 312
and 708, with all wireless services (cellphones and beepers) moving into
the new 630 area code.  The cellular providers protested that such a
move was "discriminatory on class of service" and succeeded in changing
the setup.  Their point was that the landline carriers (Ameritech and
any future competition) would have an unfair advantage by keeping 312
and 708.

The new plan is that 708 will split twice into 708, 630, and 847, and
312 will split into 312 and 773.  All fine and well, except for one
bit of fine print: cellular phones located in areas whose area code is
changing WILL NOT be required to change in the splits.

WHY?  If it is "discriminatory on class of service" to force ONLY the
wireless providers to switch to the new area code, then it is also
"discriminatory on class of service" to force EVERYONE BUT the wireless
providers to switch.

Personally, I still think that wireless overlays would've been a great
idea, much better for both wireless and landline customers than the
current mess of splits and universal overlays.

[TELECOM Digest Editor's Note: Just as with the flip-flop on 312/773,
it all depends on who you know and how well you can twist arms, etc. 
Ameritech originally said close to three million subscribers should
not have to change their area code when a small number of subscribers
in the downtown area could do so instead. The problem is, the large
businesses downtown have lawyers, and other highly placed contacts at
the state and city government level and they make a lot of noise. Why
should they have to go out and buy new letterheads and rubber stamps?
Why should they have to hire someone to reprogram their PBX equipment
who knows anything about it, etc. 

I think the aggregate cost of close to three million people having to
change *their* phone number is a lot more than a few businesses downtown
having to change theirs.    PAT]
