Confronting the Fear of Public Speaking via Virtual Environments
Confession: In the past, I’ve been extremely quick to dismiss the value of Second Life in the context of teaching and learning.
Even worse, my dismissal was not fact-based … and, if truth be told, I’ve gone out of my way to avoid opportunities to ‘gather the facts’ by attending presentations at conferences, conducting my own research online, speaking with my colleagues, etc.
So I, dear reader, am as surprised as any of you to have had an egg-on-my-face epiphany this morning …
Please allow me to elaborate:
- Yesterday, I witnessed a demonstration of Nortel web.alive (dubbed by some as ‘Second Life for business’)
- This morning I was brainstorming content with a colleague for an upcoming presentation on computing resources available for researchers at York
It was at some point during this morning’s brainstorming session that the egg hit me squarely in the face:
Why not use Nortel web.alive to prepare graduate students for presenting their research?
Often feared more than death and taxes, public speaking is an essential aspect of academic research – regardless of the discipline.
Enter Nortel web.alive with its virtual environment of a large lecture hall – complete with a podium, projection screen for sharing slides, and most importantly an audience!
As a former graduate student, I could easily ‘see’ myself in this environment with increasingly realistic audiences comprised of friends, family and/or pets, fellow graduate students, my research supervisor, my supervisory committee, etc. Because Nortel web.alive only requires a Web browser, my audience isn’t geographically constrained. This geographical freedom is important as it allows for participation – e.g., between graduate students at York in Toronto and their supervisor who just happens to be on sabbatical in the UK. (Trust me, this happens!)
As the manager of Network Operations at York, I’m always keen to encourage novel use of our campus network. The public-speaking use case I’ve described here has the potential to make innovative use of our campus network, regional network (GTAnet), provincial network (ORION), and even national network (CANARIE) that would ultimately allow for global connectivity.
While I busy myself scraping the egg off my face, please chime in with your feedback. Does this sound useful? Are you aware of other efforts to use virtual environments to confront the fear of public speaking? Are there related applications that come to mind for you? (As someone who’s taught classes of about 300 students in large lecture halls, a little bit of a priori experimentation in a virtual environment would’ve been greatly appreciated!)
Update (November 13, 2009): I just Google’d the title of this article and came up with a few, relevant hits; further research is required.
CANHEIT 2008: Enhanced Abstract
The program specifics for CANHEIT 2008 are becoming available online.
The enhanced abstract for one of my presentations is as follows:
From the Core to the Edge: Automating Awareness of Network Topology through Knowledge Representation
Ian Lumb – Manager Network Operations, Computing and Network Services (York University)
Abstract
Like many other institutions of higher education, York University makes extensive use of Open Source software. This is especially true in the case of monitoring and managing IP (Internet Protocol) devices. On the monitoring front, extensive manual configuration is currently required to make monitoring solutions (e.g., NAGIOS) aware of the topology of the York network. And with respect to managing, NetDisco automatically discovers assets placed on the network, but is unable to abstract away unnecessary complexity in, e.g., rendering schematics of the network topology. These and other examples suggest that NAGIOS and NetDisco operate in the realm of data, and possibly information, but are unable to envisage network topology from a knowledge-representation perspective. Thus the current focus is on applying a recently developed knowledge-representation platform to such routine requirements in network monitoring and management. The platform is based on Sematic Web standards and implementations and has already been proven effective in various scientific contexts. Ultimately our objective is to extract data automatically discovered by NetDisco, represent it using the knowledge-based platform, and transform a topology-aware representation of the data into configuration data that can be ingested by NAGIOS.
A visual representation of the approach is illustrated below.

Evolving Semantic Frameworks into Platforms: Unpublished ms.
I learned yesterday that the manuscript I submitted to HPCS 2008 was not accepted ![]()
It may take my co-authors and I some time before this manuscript is revised and re-submitted.
This anticipated re-submission latency, along with the fact that we believe the content needs to be shared in a timely fashion, provides the motivation for sharing the manuscript online.
To whet your appetite, the abstract is as follows:
Evolving a Semantic Framework into a Network-Enabled Semantic Platform
A data-oriented semantic framework has been developed previously for a project involving a network of globally distributed scientific instruments. Through the use of this framework, the semantic expressivity and richness of the project’s ASCII data is systematically enhanced as it is successively represented in XML (eXtensible Markup Language), RDF (Resource Description Formal) and finally as an informal ontology in OWL (Web Ontology Language). In addition to this representational transformation, there is a corresponding transformation from data into information into knowledge. Because this framework is broadly applicable to ASCII and binary data of any origin, it is appropriate to develop a network-enabled semantic platform that identifies the enabling semantic components and interfaces that already exist, as well as the key gaps that need to be addressed to completely implement the platform. After briefly reviewing the semantic framework, a J2EE (Java 2 Enterprise Edition) based implementation for a network-enabled semantic platform is provided. And although the platform is in principle usable, ongoing adoption suggests that strategies aimed at processing XML via parallel I/O techniques are likely an increasingly pressing requirement.
Cyberinfrastructure: Worth the Slog?
If what I’ve been reading over the past few days has any validity to it at all, there will continue to be increasing interest in cyberinfrastructure (CI). Moreover, this interest will come from an increasingly broader demographic.
At this point, you might be asking yourself what, exactly, is cyberinfrastructure. The Atkins Report defines CI this way:
The term infrastructure has been used since the 1920s to refer collectively to the roads, power grids, telephone systems, bridges, rail lines, and similar public works that are required for an industrial economy to function. … The newer term cyberinfrastructure refers to infrastructure based upon distributed computer, information, and communication technology. If infrastructure is required for an industrial economy, then we could say that cyberinfrastructure is required for a knowledge economy. [p. 5]
[Cyberinfrastructure] can serve individuals, teams and organizations in ways that revolutionize what they can do, how they do it, and who participates. [p. 17]
If this definition leaves you wanting, don’t feel too bad, as anyone whom I’ve ever spoken to on the topic feels the same way. What doesn’t help is that the Atkins Report, and others I’ve referred to below, also bandy about terms like e-Science, Grid Computing, Service Oriented Architectures (SOAs), etc. Add to these newer terms such as Cooperative Computing, Network-Enabled Platforms plus Cell Computing and it’s clear that the opportunity for obfuscation is about all that’s being guaranteed.
Consensus on the inadequacy of the terminology aside, there is also consensus that this is a very exciting time with very interesting possibilities.
So where, pragmatically, does this leave us?
Until we collectively sort out the terminology, my suggestion is that the time is ripe for immediate immersion in what cyberinfrastructure and the like might feel like or are. In other words, I highly recommend reviewing the sources cited below in order:
- The Wikipedia entry for cyberinfrastructure – A great starting point with a number of references that is, of course, constantly updated.
- The Atkins Report – The NSF’s original CI document.
- Cyberinfrastructure Vision for 21st Century Discovery – A slightly more concrete update from the NSF as of March 2007.
- Community-specific content – There is content emerging on the intersection between CI and specific communities, disciplines, etc. These frontiers are helping to better define the transformative aspects and possibilities for CI in a much-more concrete way.
Frankly, it’s a bit of a slog to wade through all of this content for a variety of reasons …
Ultimately, however, I believe it’s worth the undertaking at the present time as the possibilities are very exciting.
Earth and Space Science Informatics at the 2007 Fall Meeting of the American Geophysical Union
In a previous post, I referred to Earth Science Informatics as a discipline-in-the-making.
To support this claim, I cited a number of data points. And of these data points, the 2006 Fall Meeting of the American Geophysical Union (AGU) stands out as a key enabler.
With 22 sessions posted, the 2007 Fall Meeting of the AGU is well primed to further enable the development of this discipline.
Because I’m a passionate advocate of this intersection between the Earth Sciences and Informatics, I’m involved in convening three of the 22 Earth and Space Science Informatics sessions:
- Ontology Integration: A Pressing Challenge for Earth and Space Science Informatics
- Grid Technologies and Associated Infrastructures
- Putting Ontologies to Work: Real-World Applications in the Earth and Space Sciences
I encourage you to take a moment to review the calls for participation for these three, as well as the other 19, sessions in Earth and Space Science Informatics at the 2007 Fall Meeting of the AGU.
