Codifying Australian English

Evolving Identities: The English Language in Singapore and Malaysia by Vincent B. Y. OoiVincent Ooi, Associate Professor, National University of Singapore will speak on "The 5-Concentric Circles Model & the Australian English Dictionary", in Canberra, 10 October 2008:
Seminar: The 5-Concentric Circles Model & the Australian English Dictionary

Australian English is a norm-prescribing variety which is codified in the dictionary by means of markers such as ‘taboo’, ‘colloquial’ and ‘slang’. In this seminar, Professor Ooi will re-examine the use of these markers with two primary suggestions: firstly, such markers should be based on a wider body of linguistic evidence and, secondly, there is a need to go beyond such markers for a more inclusive codification. A first means to do this is to view the language in terms of a ‘5-concentric circles’ model.

Vincent B Y Ooi, PhD, is Associate Professor at the Department of English Language and Literature, National University of Singapore. His teaching and research interests involve lexicology and lexicography, varieties of English, corpus linguistics, language and the Internet, and computer-mediated communication. He is, among others, the author of Computer Corpus Lexicography, the editor of Evolving Identities: The English Language in Singapore and Malaysia, and co-chief editor of The Times Chambers Essential English Dictionary (2nd edition).

Teaching Computer-Mediated Communication for Governance

At the Varietas Multidisciplinary Teaching Interest Group on Wednesday we discussed what was required for a learning management system (LMS). What quickly became apparent was that selecting an LMS should be treated like other requirements analysis for an ICT system. Rather than start with a shopping list of features found in typical LMS, we should work out what the learning objectives are, the appropriate learning styles for that learning and then how ICT can support it.

LMS can have document creation and document/record management facilities, person to person and person to group communication, meeting management, assessment management and course delivery features. What many of these have in common is computer-mediated communication (CMC):
Computer-Mediated Communication (CMC) is defined as any communicative transaction which occurs through the use of two or more networked computers.[1] While the term has traditionally referred to those communications that occur via computer-mediated formats (i.e., instant messages, e-mails, chat rooms) it has also been applied to other forms of text-based interaction such as text messaging. [2] Research on CMC focuses largely on the social effects of different computer-supported communication technologies. Many recent studies involve Internet-based social networking supported by social software.

From: Computer-Mediated Communication, Wikipedia, 28 September 2008, at 11:06
Even the document/record management facilities and assessment, could be considered a form of communication. The record management facilities are used for communicating from now to the future, and the assessed is the assessor communicating to those who may wish to employ the student.

This analysis should work well for the courses on web design and electronic document management I present, as the topic of the course is also Computer-Mediated Communication.

To test if this would be a useful approach I tried the same technique wh9och I had used with "learning commons". A web search on CMC, returned about 2.5 million hits. Narrowing the search to the last 24 hours, produced just over 10,000 documents. This suggested the term was widely used, but the real surprise came when I narrowed the search to CMC for 24 hours at ANU, which found 4 documents, including an announcement of a seminar a few hundred metres from my office by an expert in lexicography and computer-mediated communication: The 5-Concentric Circles Model & the Australian English Dictionary, Vincent B Y Ooi, The Australian National Dictionary Centre, CEDAM Seminar Room, Building #96, 10 October 2008.

Rather than arguing the merits of Wiki, Blog, Podcast, Webinar, Feed or whatever new technology may be around the corner, it should be possible to apply the analysis developed for CMC, such as synchronicity, persistence, multimodality, privacy and security.

My courses on web design and e-document management largely address the needs of governance. This could be generalised as CMC for governance; that is using computer based systems to coordinate an organisation, or a society. In this way we can step back from the detail of how email or word processing documents should be archived in a company or a government agency and look at how computers can be used to make decisions, have those decisions implemented and satisfy the community the process was properly carried out. Different forms of CMC can then be assessed to see how they assist governance.

Thinking Systems Thinking

Dr Shayne FlintShayne Flint will give a free seminar on "Rethinking Systems Thinking", at the ANU in Canberra, 9 October 2008:
DCS SEMINAR SERIES

Rethinking Systems Thinking
Shayne Flint (DCS, ANU)

DATE: 2008-10-09
TIME: 16:00:00 - 17:00:00
LOCATION: CSIT Seminar Room, N101, Computer Science and Information Technology Building, Australian National University

ABSTRACT:
Systems Thinking refers to a set of approaches that can be used to learn about and make decisions regarding improvements to dynamically complex systems. They are distinguished from other approaches by their focus on the whole and the study of interactions among the parts of a system, rather than the parts themselves. While focusing on interactions helps us understand complex systems and identify appropriate improvements, it is necessary to use detailed knowledge of the parts and other aspects of a system to implement any improvements.

This paper addresses this issue by introducing a novel Systems Thinking approach which uses detailed knowledge of the parts to both understand the whole, and to build the systems required to implement necessary improvements.

BIO:
Shayne Flint is a Senior Lecturer at the Department of Computer Science, Australian National University, and is an active member of the department's Software-Intensive Systems Engineering group. Dr. Flint has broad industry experience and is the originator of Aspect-Oriented Thinking, a systematic approach to developing, managing and integrating the multi-disciplinary knowledge and expertise required to understand and improve complex systems.

Title: Aspect-Oriented Thinking - An approach to bridging the disciplinary divides

Author: Flint, Shayne
Institution: The Australian National University

Date: 2006

Abstract

Engineering is often described as the application of scientific and technical knowledge to solve problems. In this thesis, I support a more general view that engineering should be treated as a continuous process of learning and action that aims to make well understood improvements within dynamically complex environments of co-evolving social, man-made and natural systems. I argue that this can only be achieved by adopting an approach that systematically develops, manages and integrates the knowledge and expertise of many disciplines to conceive, develop, modify, operate and retire systems. A novel implementation of such an approach, called Aspect-Oriented Thinking, is presented.

Aspect-Oriented Thinking begins with the development and verification of a set of domain Models. Each Domain Model represents knowledge about a separate, autonomous and possibly discipline specific concern or view within a given context. Domain models are developed by engineers, scientists, sociologists, psychologists, lawyers, philosophers, economists and others, using languages and techniques with which they are familiar. Knowledge captured in a set of Domain Models is then woven together, in accordance with a set of separately developed patterns and rules, to construct, modify, operate and retire systems, including models, hardware, software, processes and simulations. This is a continuous process which, in the first instance, involves those systems used to learn about a given context and to make decisions regarding required changes. Later, the process involves those systems used to implement and evaluate the impact of these decisions.

The significance of Aspect-Oriented Thinking lies in its broad applicability to any situation in which the expertise and knowledge of diverse disciplines is required to understand and make improvements within complex multifaceted environments such as those that involve sustainable development and national security.

A proof-of-concept within the context of software engineering is provided to demonstrate the mechanics and viability of Aspect-Oriented Thinking. The results of this demonstration are used to support an argument for future experimentation aimed at evaluating the effectiveness of Aspect-Oriented Thinking in a more general interdisciplinary environment.

Multicore virtualizing power saving server at ANU

The ANU is inaugurating a new SUN T2 multicore computer, on 16 October 2008. Interested persons from the local IT industry are invited to attend:
Multicore processors such as the T2 are designed to be able to process a large number of tasks concurrently. They are ideally suited to applications such as database and web servers, where, in the case of the T2, up to 64 transactions could be processed simultaneously. To have such a capability in a single unit results not only in lower up-front costs, but in very considerable power savings. When used in conjuction with virtualization, a number of (virtual) servers can be hosted on a single physical machine, resulting in even greater savings. Such technologies form part of a suite for forming eco-responsible datacenters.

The ANU is holding a launch of a state-of-the-art T2 multicore computer, which will mark a new phase in the computer science curricula at the Australian National University. The event is scheduled for the afternoon of Thursday October 16 at the ANU and consists of:
  • a seminar on bug and security vulnerability analysis of programs by Professor Cristina Cifuentes.
  • an introductory workshop on multicore programming by Dr Peter Strazdins.
  • a reception with representatives from ANU and Sun Microsystems.
Interested persons from the local IT industry are invited to attend. Full details, including RSVP instructions.

Launch of ANU 10% by 2010

10by2010_Logo The "10% by 2010" program to reduce carbon emissions at ANU will be launched the Innovations Lecture Theatre, 9th October, 3pm followed by afternoon tea:


Did you know that nearly 10% of ALL Energy consumption in Australia is consumed by appliances in standby mode?

Commit to reducing your emissions and you could win some FANTASTIC prizes!

Launching 10% by 2010!

How often do you think about your carbon footprint?

How often do you wonder whether you can make a difference?

At ANUgreen we have worked out that:

  • If all staff and postgraduate turned off their monitors when they were not at their computers, we could save 1,000 tonnes of CO2
  • If all staff and postgraduates turned off their computers overnight (check with your IT staff that this is possible), we could save 5,000 tonnes of CO2
  • If all the office lights were turned off during non-working hours we could save 2,500 tonnes of CO2
  • If 25% of people who currently drive to the ANU decided to carpool, we could save 5,000 tonnes of CO2
And that all adds up to 10% of our consumption (excluding transport).

How hard is that?

If all the actions above were implemented, we could save 10% of our current energy consumption (not including carbon emitted through transportation).

Easy.

Linking Research and Teaching Swap Shop
Friday 24th October 2008 ...

Purpose

The idea of the swap shop is to share interesting practices associated with linking research and teaching to benefit student learning. The key question for all participants is “What aspects of the practices I have learnt about today could I adapt for use in my courses / school/College?”

Linking research and teaching

There are four main ways of linking research and teaching:

• Learning about others’ research
• Learning to do research – research methods
• Learning in research mode – enquiry based
• Pedagogic research – enquiring and reflecting on learning

Today’s session is particularly focussed on interesting practices to engage students in the first three ways.

Participation
All academic staff are encouraged to participate. Please bring 20 copies of your interesting practice (1 side of A4 is all that is needed). If you are unable to attend on the day, but would like to send in details of an interesting practice ...

Organisation
Sitting on tables of three, you will each have 5 minutes to summarise your interesting practice to your two colleagues and 5 minutes to answer their questions.

Template
A suggested set of headings to summarise your interesting pratice includes:

• Title of interesting practice
• Name and contact details
• Context e.g. department, course, year and number of students
• What do students and teacher do? – This is the key heading
• Hot tips
• Does it work?
• Issues and how have you dealt with them

Timetable

How to Create On-line University Courses in Electronic Archiving: Part 15 - Redesign for 2008

Last year I developed and ran a short course at ANU on Electronic Document Management, reporting as I went along. The course went reasonably well and is being offered again in 2008, along with modules by others on Material Science , Innovation Management and Data Mining. Also I am to produce a module on Information Architecture and suggested one on Green ICT. But the first priority is to revise the e-document management course from last year, applying what I have learning about blended learning in the interim. Also I would like to change the emphasis from that of using electronic records to get work done more efficiently, rather than the emphasis of records managers for keeping records. There is no value in keeping records, electronic or otherwise, there is only value in what those records can be used for.

Reducing the amount of content

The 2007 e-document module, which is available via my Moodle system, was based on the material I developed for the ANU course "IT in e-Commerce" (COMP3410/COMP6341). My part of the course was "Metadata and Electronic Document Management for Electronic Commerce". As the module developed I also included material from " Writing for the web" (a short course I had run for local government) and "Extreme web design" (used in ANU course "Networked Information Systems" COMP2410/6340).

There was far too much material for a 12 hour module. The original intention was for the web design and web writing material to be in a separate short module, but that one did not end up running in 2007, thus the temptation to pack all the material into the module which did run. So now what I can do is remove some of what was in the e-document course and put it back in the web course where it can be given the depth it deserves.

No accreditation

The intention was also to apply for accreditation of the course from the ANU. However, the advice was that the 12 hour course was too short to practically fit with the ANU's longer courses. The course would need to be expanded to make it at least a 3 credit point course (half the lenght of the usual one semester courses). This would make the unit far too large for 12 contact hours. The obvious solution would be to add work for the students to do in their own time away from the university, turning this into a blended course. But that would change the character of the course and is something which will have to wait for later.

New content

The course was designed for public servants and based on my experience when in the Australian Public Service. In particular it drew on the report "Improving Electronic Document Management: Guidelines for Australian Government Agencies" which was prepared by a committee I chaired. The description of the module mentions the National Archives of Australia's "Designing and Implementing Recordkeeping Systems" (DIRKS) strategy. However, this was only mentioned briefly in the module.

DIRKS Overview

NAA provide a very detailed manual for their eight step DIRKS strategy, based on the international standard ISO 15489 "Information and documentation - Records management". (Part 1 is the actual standard and Part 2 is the guide)
One Step Process

In addition, I mentioned, but did not cover in detail "Note for file: A report on recordkeeping in the Australian Public Service", Management Advisory Committee , 31 August 2007. The MAC report suggests a simplified version of DIRKS and states that National Archives developed a quicker and more practical one-step process that complies with ISO 15489. However, the document contains no reference to where this one step process is documented and the link to an Australian Bureau of Statistics case study ‘Keep the Knowledge’ is incorrect.
A simplified one step process would be useful for this short course, as the intention is not to turn out trained records managers, but to provide public servants with as much as they need to know in relation to electronic records. However, without a document which actually details what the one step process is I will have to make up my own.

Building supercomputers from computer game chips

Eric McCreath/Eric McCreath is giving a seminar at the ANU on building supercomputers from computer game chips. He will be talking about using the Cell Broadband Engine (from Sony's PlayStation 3 game console) and the NVIDIA 8800 GPU (from PC gaming graphics cards) for scientific applications. The seminar is free and there is no need to book:

DCS SEMINAR SERIES

Using the Cell Broadband Engine and NVIDIA 8800 GPU for Computational Science Applications: A Particle Dynamics Comparison

Eric McCreath (DCS, ANU)


DATE: 2008-09-25
TIME: 16:00:00 - 17:00:00
LOCATION: CSIT Seminar Room, N101


ABSTRACT:
The NVIDIA 8800 Graphics Processing Unit (GPU) and the Cell Broadband Engine employ a vast amount of parallelism to produce low cost high performance systems which dwarf standard desktop processing units in terms of floating point calculations. These systems offer great potential for computational science applications. This presentation compares the programming model, implementation strategies and realised performance achieved on these two systems for implementing a simple particle dynamics simulation code. Both systems were found to give considerable performance improvements over high-end uni-processor machines. The Synergistic Processing Elements (SPE), on the Cell, can not directly access main memory. This complicates initial implementation compared to the NVIDIA GPU, however, fully exploiting the complex architectures of both systems is equally challenging.

BIO:
Eric McCreath completed his Ph.D. degree in 1999 from the University of New South Wales. This was on research involving Inductive Logic Programming(ILP) which is a sub-field of Machine Learning. He joined the Basser Department of Computer Science(now the School of Information Technologies) at Sydney University in 1999 as a lecturer and then in 2001 he joined the Department of Computer Science at the Australian National University. Dr McCreath currently holds a lecturing position at the ANU and is pursuing research in the Computer Systems research group.

Twelve Canoes

Twelve Canoes is a multimedia web site following on from Rolf de Heer's film 10 Canoes . It features short multimedia works with the Yolngu people of the Arafura swamp. Wile the audio and visual content is breathtaking, the site is let down by poor web design. The designers shopuld implement accessibility features for the site and correct the errors in the HTML code to allow the site to be more widely used for education.

The site assumes a high spped Internet connection and even in Canberra on my wiless Internet link I had diffciulties. The web site has some text for display (excerpts below) to those who are unable to see the video. However, this is not normally apparent to the viewer, who will have to wait for video to download, unless they are using a text only or specially adapted web browser. It would be better if the site offered a text menu which allowed skipping the video rich content, for those on a slow link.

Some years ago I was invovled in projects to provide indiginous ciolutural content online,. Those suffered from taking too academic and textural approach to web based content. Twelcve canoes goes to other extreme and suffers from too little thought as to text and indexing inforamtion.

Unfortunately the web site has invalid HTML markup and some accessibility problems. When I attempted an accessibility test of the site, all I got was the message "Parked Page for 12canoes.com.au".

We are the first people of our lands.

These are some of our stories from where we have lived so long.

Yolngu: The literal translation of Yolngu is simply, "the people", but it is used nowadays as a term to describe the group of Australian Indigenous people (Aboriginals) living in or originating from central and eastern Arnhem Land in Australia's Northern Territory.

Balanda: A word meaning "white person(s)", derived from the word "Hollander"...the Dutch were the first white people to come into contact with the Yolngu.

Macassan: The Macassans, from the island of Sulawesi in Indonesia began visiting the north coast of Australia centuries ago. Their trade made the Yolngu a very powerful grouping economically. Such trading was stopped by the government in the 1906-07 season, and the economy of the region was destroyed by the imposition of Balanda law. ...

We are the Yolngu people of Ramingining, in the northern part of Central Arnhem Land in Australia's Northern Territory.

Ramingining is a town of about 800 of our people. More of our people live on outstations different distances from town. Also about 50 Balanda live here.

The nearest other town is Maningrida, more than two hours drive away except in the rainy season, when we can only fly there.

In Ramingining we have a store, a clinic, a school, a new police station, an arts centre, a resource centre, houses and not much else.

But we have history and culture here, that our ancestors have been growing for more than forty thousand years.

They passed that culture on from generation to generation. Now it's our turn to pass it on, not just to the next generation, but to people everywhere, all over the world.

Combined data center and solar power station for Canberra

A study commissioned by the ACT Government and ActewAGL has found that a large-scale solar power plant is feasible in Canberra: "Solar Power Plant Pre-feasibility Study". If re-elected, the government will seek expressions of interest to build the plant. As suggested to the Chinese government in 2003, I propose the plant be built on the roofs of new data centres and warehouses in industrial parks. This will allow the land under the plant to be put to use, provide power for the data center and industrial buildings. It would also overcome environmental problems with the previously proposed data centre for Canberra.

Building Design

The complex would use a standard industrial building design, with a roof strengthened to hold the solar collectors. Most buildings would be initially used as low cost warehouses and only fited out as data centers when required. The data centers would use a proven, simplified modular design for equipment, which would be placed on a simple sealed concrete floor. The height of the warehouse building would be used to reduce air conditioning requirements with proven low cost techniques.

Data Center Customers

Scientific customers, such as ANU's supercomputer center and government agencies, could be large scale tenants to anchor the development. Some ancillary office space could also be provided.

Twinning

To allow for backup data supplies and exploit the daily solar cycle, the center could be twinned with centers in other time zones. While concentrator solar power stations can store energy, there is still a peak power supply during the day. This peak power could be most efficiently utilised by the data centre under the collectors. A center in another time zone, such as near Perth, would have a peak at a different time of day and could take over some of the processing load from Canberra, as well as providing a backup.

Sighting

The feasibility study raised the issue of the visual intrusiveness of a large field of solar collectors. If placed on top of a warehouse, in industrial parks, the collectors would be less visible. The industrial park could be designed to high environmental standards, retaining natural vegetation around the buildings to soften the visual impact, with the buildings coloured to blend in. In addition the opportunity could be taken to collect high quality water from the complex, for use in Canberra.
Solar Power Plant Pre-feasibility Study
Executive summary

This Solar Power Plant Pre-feasibility Study was undertaken for ActewAGL and the ACT Government (the joint parties) by PB. Its purpose was to investigate solar power generation technologies, identify an appropriate solar technology for the ACT, and establish the economic viability of a solar power facility.

Technology for producing electricity from solar energy is technically proven for both PV and solar thermal technologies. 354 MW solar thermal plants, using trough technology, have been operating in the USA since the 1980s and new plants of this type (between 50 MW and 70 MW) are now coming into service in the USA and Europe. Other solar thermal technologies that are not yet in commercial use are power towers, paraboidal dishes and Fresnel systems. Large multi-megawatt PV plants, to approximately 50 MW, are now in operation. Solar technology is expensive, and significant financial assistance from government is available to the developers and operators of new plants. There is significant local community and market support for solar power generation.

This study identifies a 22 MW project that uses solar thermal trough technology, similar to new overseas plants, as the best option for the ACT. This technology has been chosen because of its substantial operational record (more than 20 years), lower cost compared to other solar technologies, and use in new commercial plants in the USA and Europe.

The plant will produce enough electricity for approximately 10,000 Canberra homes and the project cost, before government assistance, is estimated at $141 million (including land and infrastructure). A site of 120 ha will be required and if engineering, planning and environmental work commenced immediately, it is envisaged that a plant could be
commissioned by 2012.

An alternative option is a large PV cell-based plant. To produce the same amount of electricity (that is, to service 10,000 homes), 75 ha of land would be required and the plant would have an electrical capacity
of 57 MW. This would be one of the largest PV plants in the world but the risks would be lower than the solar thermal plant, reflecting the more mature status of PV technology, its predictable performance and
cost. However, the total project cost of $424 million is high.
It is recommended that this pre-feasibility study be followed by a feasibility study that includes engineering studies, ongoing commercial evaluation, financial modelling and environmental and planning studies.

A staged study, extending over eighteen months, could be conducted and lead directly into procurement and construction. However, trough technology is not cost effective for a staged development at the size
of the proposed ACT plant. Even though the solar field is modular, the balance of the plant is not suitable for staged development without incurring significant additional costs. A financial evaluation of the solar thermal project, assuming 100% equity funding, a 9.5% Weighted
Average Cost of Capital (WACC) and a 20-year project life was undertaken, Key results were:
  • a levelised electricity cost of $106/MWh for a net project cost of $47 million. This is for a plant cost of $2,500/kW, which is forecast for the technology in Australa, and allows grant funding of 50% of the project capital cost;
  • the relatively high cost of generation is due to the high capital cost of plant itself, the high proportion of infrastructure and land (38% of project cost) and the relatively low productivity (measured by the 42% capacity factor).
  • larger plant size would significantly improve the economics by spreading the infrastructure costs over a larger productive plant and capturing economies of scale of the production plant itself. For example, doubling the plant to 44 MW would lower electricity cost by about 25%;
  • 57% grant funding was required to reduce the levelised electricity cost to $95/MWh which is the expected Power Purchase Agreement (PPA) electricity selling price;
  • higher solar radiation levels such as at Mildura would lower levelised electricity cost by about $50/MWh, or 17% (before rebates); and
Government grants and subsidies have been fundamental to the facilitation of the growth of solar energy generation around the world. The requirement for government support also applies to this project. This
project would appear to fit well with current Australian and ACT Government policies (such as the move toward zero/low carbon emissions and renewable generation) and it supports ActewAGL regulatory
requirements for renewable energy.

The Sun is a reliable but intermittent and diffuse source of energy. There is strong daily and seasonal variation and availability, and it may be limited by cloud cover. To extend power generation beyond periods of sunlight and to allow a steady supply of heat, two approaches to solar thermal plant energy storage were proposed:
  • storage of heat at the plant and use of this heat when direct sunlight is not available. This would give an extra four to six hours operation without the Sun shining; and
  • use of natural gas as an auxiliary fuel to supply heat as an alternative. If this is supplied by the waste heat from a cogeneration plant, an additional 47 MW could be generated by a gas turbine. The use of gas auxiliary fuel does not affect the eligibility of solar generation as renewable or green energy under the current regulatory arrangements, but may have some impact on community perceptions.
The solar thermal plant would occupy a significant area and unless it is well-shielded, it is likely to be a prominent visual feature. It would combine the physical features of the large solar field with a small
thermal power station, possibly with a gas boiler or small gas turbine for back-up. While the solar technology itself is considered to be relatively benign, it is likely to require consideration environmental issues, that are similar to those raised by a small gas-fired power station with the additional issues raised by the large land area and visual amenity.
Formal evaluations of potential sites for the solar facility will occur only if the project is found to be viable and progresses to a more detailed study, at which time such sites would undergo a rigorous environmental and planning assessment.

Study Green ICT at the Australian National Unviersity

The ANU is having an Open Day, 30 August 2008, 9am to 4pm. As well as the topics and projects on display, it is worth keeping in mind that students learn about newly emerging topics (called by the ANU research-led education) and students can make up their own projects. Undergraduates and postgraduates in the College of Engineering and Computer Science, for example, can work on areas such as Green ICT. This is not as easy as doing work from an old textbook, as there are no set answers yet.

Some of the students are unhappy because I have set an assignment question asking them how they would reply to the environmental requirements in the recent Government computer tender. At present there are no clear answers (which is what the ICT industry is working on and why it is an interesting topic). But then if this was easy it would not be a suitable topic for Australia's top university. ;-)

ANU College of Engineering & Computer Science

Venue: ANU Sport and Recreation Centre [19]

My Last Lecture

Last Tuesday I told the COMP3410 students at the Australian National University that this was my last lecture. What I did not expand on was that this was not just the last one for my series in this course this semester, but I did not intend to give any more lectures at ANU, or anywhere else. It was time I put into practice what I have been learning about blended learning: combining online teaching and live group work.

I don't like giving lectures to groups of eighty or so students. It is very hard to get any feedback. In some lecture theatres difficult to see the students and in some of the old steeply tiered ones I get a a sense of vertigo: looking up from what feels like the bottom of a well.

I never liked attending lectures and thought them not an efficient way to learn. When I arrived at ANU as a visitor I fell into the lecturing role almost by accident, being invited to give one or two and then blocks of six.
For several years I have thought that it should be possible to teach at tertiary level using online systems. The Australian Computer Society (ACS) runs its Computer Professional Education Program as a purely online, postgraduate education course. As Director of Professional Development Board at the ACS, I learnt a lot about the process from David Lindley, who carefully structured the ACS program; see his: "Computer Professional Education using Mentored and Collaborative Online Learning" (in IJCIM special issues on e-learning, Vol.15 No. SP4, November, 2007). However, ANU is an elite, research lead organisation and it was not clear if a completely online course using such techniques would fit in.

Last June I attended a seminar on the MIT iCampus, which indicated that a blended approach to learning would be acceptable and effective at a respected university. The blended approach avoids purely online distance education. Part of the course is online using a course management system, but other parts are in a classroom with lecturers, mini lectures, demonstrations, group discussion, group and individual work. I then went on a year's investigation into , , and .

In the middle of this I was asked to run a short course on "Writing for the Web" for a local council. To do this I set up a Moodle course management system and loaded it with a cut down version of the content I had prepared for ANU courses. The council staff set up an electronic classroom and I presented the course live in the room using the Moodle system.

The small group computer assisted approach worked so well that when I was asked to prepare a short course on e-documents at ANU for public servants I used the same technique. This also worked well and I have been asked to give further such courses, but I had the uncomfortable feeling this was not a "proper" university course.

I was encouraged to submit the short course for approval as a formal unit of the Unviersity. This was rejected, not because of the teaching method, but because it was too short and did not have enough content to be a useful size to fit into regular programs.

The pragmatic approach to making the short course longer was to add homework (the short course had been entirely in the classroom). Adding 50% of material the student does remotely online would bring the course up to the required size. This would also turn it into a true blended course.

In the interim the ANU attitude to such courses had changed. The university officially enthusiastically supports them, with funding and staff support for their development. The ANU College of Law offers a Graduate Certificate in Australian Migration Law & Practice using distance education (online) and "intensive" (blended) modes and is approved by the Australian Government. Traditional academics are grudgingly starting to accept there is a role for such techniques. However, what remains are the challenges of the mechanics of having the infrastructure to support the courses, such as speciality equipped classrooms and extensive online systems and how to apply this to advanced courses.

The remaining challenge is how to apply blended techniques to research based learning. With typical vocational online courses one group of people prepare the course and then another deliver it to a large number of students over an extended period. The courses have a very rigid structure and fixed content. This is a very good business model for educational institutions, as they can get the maximum return on the investment in the courseware delivered to a large number of students over a long time.

But research lead education requires new research results to be incorporated in courses quickly. This requires frequent changes to the content and also requires staff who understand the research to help the students. That is a difficult and expensive process. The ACS partly gets around this problem by using open assignment questions in its postgraduate courses: the students themselves conduct the research, looking into the latest findings in ICT. In a way the staff are just there as coaches, to help the students along with the process, without necessarily understanding the details of what the students find. This is the essence of how research is done at universities (I have learnt a lot from the students doing research projects I have supervised). However, more guidance will be needed for the average undergraduate student.

So much for the theory: time to get on and do it. What I am to do is adapt the material I previously prepared for traditional lectures so it can be delivered in a blended mode: short lectures, workshops and tutorials. Ideally the same content can then be used as part of a traditional course, in place of my previous lectures, as short courses in the normal university semester and as short intensive courses.

Web 2 format for Environmental Product Data?

The Department of the Environment, Water, Heritage and the Arts (DEWHA) has issued a Request for Tender for Provision of Desktop, LAN, Helpdesk and Midrange Services. This asks for detailed environmental performance data, so I asked my ANU metadata students how that could be supplied via the web:
COMP6341 students: The Department of the Environment, Water, Heritage and the Arts (DEWHA) issued a Request for Tender for "Provision of Desktop, LAN, Helpdesk and Midrange Services" last week. The 278 page tender document includes extensive and detailed environmental requirements.

Tenderers are required to provide the information specified in the IEEE 1680 environmental standard. The Electronic Product Environmental Assessment Tool (EPEAT) is a spreadsheet manufacturers can use to fill in to rate their products and then upload the results to a central database. The information can be displayed as a web page and can be exported as a spreadsheet.

But less than a thousand computer products are listed by EPEAT. Many more have not been rated using their system and manfacturers may also have to list their products under schemes in Europe and elsewhere. Manufacturers already provide product information on their web sites. Having to supply data in different formats to different rating organisations is an addition burden.

Look at the EPEAT entry for the DELL OptiPlex 745 Energy Smart:

  1. What are some options for marking up the information about the DELL OptiPlex 745 in an HTML and/or XML format, so it could be read by the general public as a web page and also automatically input the databases of different rating bodies? The web page should similar to the ones Dell supplies, but have metadata embedded in it.
  2. What are the benefits of different ways to mark up the metadata?

How to Create On-line University Courses in Electronic Archiving: Part 14 - Getting it accredited

Last year I developed and ran a short course at ANU on Electronic Document Management, reporting as I went along. The course went reasonably well, but it was not intended to be recognised by the Unviersity for credit towards a qualification. To get the course accredited is a complex process. Also there is the need to make sure the infrastructure is available to run it regularly and that it fits in with other courses.

The system used at ANU allocates courses credit points, with a typical one semester course being 6 points. However, the course I ran would only be the equivalent of 2 credit points and so would not fit in with other courses. It did not seem to make sense to make the course three times as large to make it up to 6 points, but 3 points seemed a reasonable level.

The course I had run was only face to face, while there was material online, it was assumed the student would do no prior preparation and complete all the work during the sessions in the classroom. This was done to make it easier for working part time students, but is not typical for the average course and probably is not the best way for students to learn. The students need time for reflection and this can't be done in a hectic workshop.

Having students do homework also saves on university resources. However, it is not free: there are substantial resources needed to make sure the online system the students use from home is working when they need it and that staff are available online. Also there is the need to carefully structure the course so that students can actually do the remote component. With competing demands for time it can be very easy to let the home work slip. It needs to be divided into reasonable size units and with assessment to reward the student as they complete the units.

But that said, it seemed to make sense to add 50% extra content to the course, to be delivered online and through student exercises. The exercises I had already prepared were far in excess of what was possible to do in the classroom and should be able to be expanded online.

The ANU is now setting up Flexible Learning Units in its Colleges, so I went along to see, Kim Blackmore, Coordinator of the Flexible Learning Unit for the
College of Engineering and Computer Science. Kim suggested looking at the way the courses are run for the ANU's Graduate Certificate in Australian Migration Law & Practice. Certificate is a good example, as it is run by the ANU College of Law, but is open to people without a legal background (usually people applying to be Migration Agents), as well as lawyers.

Students can choose either on-line teaching or face-to-face "intensive " classes in Melbourne or Sydney for the course. The ANU's Web CT system is used for delivery and on-line contact with tutor and other students. The courses are run several times a year.

An example of one of the courses is Australian Migration Law and MARA 1 (LAWS8167). The course uses written assignments, quizzes, case studies and simulated client interview and tribunal appearances (not sure how they do the client interviews online). There are two traditional printed paper text books for the course, as well as the online material. The course costs $2,100 for the 6-units (not including the textbooks). The same fee is charged for the online and intensive versions.

Curiously, there are few details of how the course is run, or even that is using online techniques. Given that universities are intensively competing for students and the ANU is seen as being a bit inflexible, I would have thought ANU would be wanting to showcase its flexible learning courses.

The ANU currently uses Web CT and I can look at how this was used for LAWS8167. But the university is planning to install a new Learning Management System (LMS), so it would make sense to prepare a new course using that. Hopefully Web CT will be replaced with an open source system, such as Moodle or Sakai.

New Applicaitons of Metadata and Electronic Document Management for Electronic Commerce

Each year I give lectures at the ANU on Metadata and Electronic Document Management for Electronic Commerce as part of Information Technology in Electronic Commerce ( COMP3410/COMP6341). While the principles don't change, and the technology does not change that much, each year I like to freshen up the course with some new examples. The area covered includes document representation, meta-data, data management, digital library, electronic document management and e-commerce.

It might seem surprising that the principles don't change, but e-publishing is much the same as publishing of books was, minus the paper. Similarly management of e-records is like managing paper files, without the paper. The difficult task with this is to convince computer scientists, software engineers and information systems students that it is worth worrying about the the details of policies and practices and that these are difficult topics.

Technologies have changed a little with XML being firmly established. This makes it important to point out to the students that there was a time before XML, HTML and the web and there will be a time after them.

One area worth looking at with recent developments are XML based office document formats. The controversy over ODF and OOXML as international standards has calmed down somewhat, and a detailed look at the similarities and differences, strengths and weaknesses of these (as well as alternatives) would be useful.

The examples used change most often. What last year was a complex challenge, such as how to build a global electronic publishing system for the world's ICT research has now largely been solved.

Some areas I was thinking of looking to for examples were:
  1. In flight E-publishing for the airline industry
  2. e-Courts
  3. e-enabling carbon trading and energy reduction systems

Publications by Kim Beazley

Professor Kim Beazley has been appointed Chancellor of The Australian National University. He is currently Professor of Political Science and International Relations at the University of Western Australia, but is best known as a politician. An academic is judged by what they publish, so I ought I would do the same sort of quick check of Professor Beazley I would do of anyone else.

A search of the Political Science and International Relations site of UWA gives the bare minimum of information. Professor Beazley has a staff web page, but this just has his name and contact details, with no list of publications, research or courses. On the "Research Interests" page he is listed under Australian political institutions, Public affairs, Australian Government and Politics and Australian foreign policy and diplomatic history, Global and regional governance. But there are no details of research conducted.

The "Contact Us profile" page lists Research Interests as:
  • Defence policy
  • US alliance
  • Middle East
  • Foreign policy issues
  • Australian politics
  • Government
But again there is no actual research or courses detailed.

A Google Schollar search for Kim Beazley as an author produced 44 results (including some from another researcher of the same name in the conservation field). However, as he only took up his UWA position in 2007, there are no publications for that period. Also the list includes some references to Professor Beazley's father Kim Edward Beazley.

Excluding papers which are obviously from other "Beazley" leaves 26. These show a long term interest in defence and foreign policy and domestic public policy issues:
