The iPad is Revitalizing Academic Publishing

Greetings from the Australian National University where
the new ANU Librarian, Roxanne Missingham, is speaking on "Is the iPad Killing Academic Publishing?". Clearly the answer is no, mobile devices are not having an adverse effect on scholarly publishing. Roxanne argues that like previous information technology which did not kill its predecessor (radio, TV, Movies). Old technologies adapt to work alongside the new. Printed books will adapt to complement digital publishing. From Socrates with writing onwards, educators have worried that students will substitute information technology for thinking. Tablet computers can be used for quickly looking up a source or making a quick note, but Roxanne argues the tablets are not up to the job of intense detailed scholarly research, where many large documents have to be accessed and annotated. She asked how to integrate discussion of scholarly issues before the final journal article is produced (which would seem to be a good use for mobile devices).

Roxanne asserted that e-publishing need not be a race to the bottom and that there is a role for well written, well edited quality publications. There are also small but significant differences shown by research on print and digital texts. Tests of college students showed that using eBooks produced sligtly less comprehension. But I suspect this may be just a problem with the quality of current screens, as they have higher resolutions, indistinguishable from print.

Roxanne pointed out that digital systems can be used to create data representations not possible on paper, such as 3D animations. This creates a challenge for librarians as to how they preserve this content for long term access.

Roxanne asked what interface will suit academic publishing, which may need to be richer than that designed for the casual user. Where will collaboration take place online: in closed private forums, or in the public domain?

COMPUTER SCIENCE COLLOQUIUM SERIES

DATE: 2012-04-04
TIME: 11:00:00 - 12:30:00
LOCATION: Seminar Room (N101), CSIT Building (Building 108, North Road)
CONTACT: Malcolm.Newey@anu.edu.au

ABSTRACT:
In the twenty first century we are using i-pads, online data and digital resources for so much of our study and research that some postulate the end of the book. I will argue that new forms of knowledge creation and sharing can only be successful because of our book culture. Reading is the most vital skill for all of us in the twenty first century and criticisms of books have been part of our culture for decades. Print is vital for access to knowledge, and the new digital environment sees a shading or greying of published knowledge and data. This means we need to look at knowledge and scholarly information in a completely new way. I hope to be quite provocative.


BIO:
Roxanne Missingham is the new University Librarian (Chief Scholarly Information Officer). Until February, she was the Parliamentary Librarian for the Parliament of Australia, and prior to that was an Assistant Director-General (Resource Sharing Division) at the National Library of Australia for five years. She has over twenty years of senior management experience in Australian public sector libraries, and brings with her a wealth of knowledge of enabling technology to provide scholarly information. Roxanne has also written extensively on the role of contemporary libraries.

Modern Trends in Machine Computation

The paper "Modern Trends in Machine Computation" was published in Supplement to the Australian Journal of Science, 21 February 1948 (Volume X Number 4). This is by Trevor Pearcey, then an officer at the Radio-physics Laboratory of the Council for Scientific and Industrial Research (predecessor of CSIRO). This describes the state of the art in what would now be called computing. The paper starts by discussing the difference between analogue and digital machines. The accuracy and flexibility of digital machines is pointed out. Charles Babbage's difference and analytical engines are mentioned as precursors to model digital machines. The work of Dr. Vannevar Bush at MIT is noted. The difference between simple repetitive computations needed by commerce and complex scientific calculations is discussed.

Pearcey provides a diagram of the components of a digital computer, which is essentially the same as would be used today in teaching, except for the terms used. The diagram (Figure 2) is captioned "The Organic Structure of a Computer", and has a "Control Organ" at the centre, surrounded by and connected to, the "Memory Organ", "Output Organ", "Arithmetic Organ", and "Input Organ". The difference between decimal and binary number representation are then discussed and the advantage of binary for processing by simple telephone type relays. Valve based electronic computer circuits are then discussed, with a circuit of a binary counter showed.

Memory devices are then discussed: punched tape, punched cards, magnetic tape or wire, photographic film, relay and valve registers, acoustic tube delay lines, and electrostatic storage (in a device similar to a Cathode Ray Tube). The timing needed for sequential computation is then discussed.

The Automatic Sequential Control Calculator (ASCC) at Cruft Laboratory, Harvard is then described in detail (it was an electromechanical relay machine). ENIAC from the Moore School of Engineering is then compared with its predecessor, ASSC from Harvard. The MIT Differential Analyser is described last.

Pearcey then speculates on future developments, with more memory capacity and faster speeds being desirable. The the USA's EDVAC project and UK's ACE are mentioned.

Pearcey ends with an often quoted, and from my reading of a facsimile of a copy of the actual journal article, misquoted sentence:
"In the non-mathematical field there is a wide scope for the use of the techniques in such things as filing systems. It is not inconceivable that an automatic encyclopaedic service operated through the national teleprinter, or telephone system, will one day exist."
When asked about this in his talk in Canberra, 23 May 2011, James Gleick, author of "The Information: A History, a Theory, a Flood", said he doubted that such a paper would mention computers in 1948. Having read the paper I can confirm it does discuss "Computors" (note spelling), "computing" and specifically electronic digital computers. The body of the paper does not discuss the use of computers for handling non-numeric data, but the mention "filing systems", and an "encyclopedic service" operating over a national teleprinter, or telephone system, indicates that this was in Trevor Pearcey thoughts.

What also makes this paper significant is that unlike many dreamers who speculated about computers, Trevor Pearcey was leader of the team (along with Maston Beard) who built CSIRAC (CSIR Mk 1), the fourth stored program digital electronic computer (1949).

This paper deserves to be more widely known. The poor quality facsimile copy I obtained through the Australian National University, appears to be from a USA based document service. This paper should be digitised at high resolution and transcribed and placed online, so its place in the history of computing can be properly recognised.
