It ought to go without saying that
the goal of diversity of gender or ethnic
origin does not generally conflict with
excellence in research. For instance, in
recent years my department has interviewed several women candidates who
were uniformly superior to their male
counterparts.
However, in specific faculty searches it may be that the potential research
stature of a certain white male candidate is perceived as exceeding that of a
certain female or minority candidate.
The latter may be stellar, but the former’s intellectual light shines just a bit
brighter. If the discrepancy is comparable to the rather high level of uncertainty inherent in measuring a candidate’s potential, some may invoke the
additive argument.
However, this argument seems to
rest on two questionable assumptions:
departmental excellence (however
measured) is the arithmetic sum of the
individual levels of excellence of its faculty members; and the success of an individual researcher is independent of
the surrounding environment.
Both are wrong. Excellence in research (individually or across a department) is a nonlinear function of interdependent factors. For instance, in a
department that makes itself attractive
to a broader pool of graduate students
through the composition of its faculty,
all researchers benefit from the resulting potentially improved quality of the
department’s student body. This also
holds when attracting new colleagues,
including so-called superstars. When
female or minority candidates are at,
say, the top of the list in a particular
search, they (like everybody else) also
consider a department’s environment
when choosing which job offer to accept. Moreover, a more welcoming, collegial, diverse faculty often leads to better and more frequent collaboration,
as well as to more vibrant research.
The question is not whether to compromise between excellence and diversity but how best to foster excellence,
with diversity a part of the equation.

said computer science is “the only
scientific community that considers
conference publications as the prima-
ry means of publishing our research
results,” asking, “Why are we the only
discipline driving on the conference
side of the ‘publication road?’”
As an old timer, I can say that in the
early days, there was a belief (conceit
might be a better word) that the field’s
pace of discovery was happening so
quickly that only conferences, with
subsequent prompt publication of pro-
ceedings, could communicate results
in a timely manner. As a corollary, the
traditional peer-reviewed published
literature review fell behind, as it was
relieved of temporal pressure through
the published proceedings.
These days, the pace of discovery
in the biological sciences, including
molecular biology, genomics, and
proteomics, far exceeds that of computer science. Yet the gold standard
of publication in archival journals
continues. It is the ultimate irony
that computer science, along with
various disciplines in the physical sciences, employs the tools developed by
computer scientists to ensure timely
dissemination of research results
through the online editions of their
publications. Science, Nature, Cell,
and other leading journals routinely
present their most important articles
in online form first. If, perhaps, computer science would make greater use
of its own tools, the shoemaker’s children would no longer go barefoot, and
published proceedings would fade
into its proper historical niche.

more to celebrate in RDBms history
Gary Anthes offered good reporting but
also some serious errors concerning
pre-RDBMS history in his news article
“Happy Birthday, RDBMS!” (May 2010),
saying “In 1969, an ad hoc consortium
called CODASYL proposed a hierarchi-
cal database model built on the con-
cepts behind IMS. CODASYL claimed
that its approach was more flexible
than IMS, but it still required program-
mers to keep track of far more details
than the relational model did.”
Please compare with the following
basic facts as reported in Wikipedia:
“In 1965 CODASYL formed a List Pro-
cessing Task Force. This group was
chartered to develop COBOL language
extensions for processing collections
of records; the name arose because
Charles Bachman’s IDS system (which
was the main technical input to the
project) managed relationships be-
tween records using chains of pointers.
In 1967 the group renamed itself the
Data Base Task Group and in October
1969 published its first language speci-
fications for the network database
model, which became generally known
as the CODASYL Data Model.”
The Integrated Data Store (IDS) has
been in continuous productive use
since 1964, running first on GE 200
computers. In 1966, it began support-
ing a nationwide, 24/7, order-entry
system (OLTP). And in 1969, running
on the GE 600, it began supporting a
shared-access (OLTP) database, com-
plete with locks, deadlock detection,
and automatic recovery and restart.
