visualisationMicrosoft Excel Network Analysis Add-InTwo weeks ago I purchased a new computer, which came with Microsoft® Vista Business loaded. I haven't gotten used to Vista yet and I am not sure I really like it. That said I've always liked Excel, and Excel 2007 seems better than ever. One of the really nice add-ons is Microsoft .NetMap , which installs a template capable of doing some rudimentary network analysis. Consider the diagram below, which is my email traffic, displayed using a Fruchterman-Reingold force-directed spring algorithm.
The add-in analysed Outlook 2007 and identified all 532 unique vertices and the corresponding 994 unique edges that make up my e-mail network. It also identified the density of the network as 0.004, which is quite sparse given 1.000 is the possible score. Consider now the same network displayed in a spiral format. ...

KM Singapore 2008Next week I am attending KM Sinagapore 2008 . I am presenting a seminar and workshop called Using BNA™ Techniques in Project Management . I am also participating in the knowledge café as a presenter. I will be presenting Applying the RAAAKERS™ Diagnostic to Understand Management Stress Points and Assure Project Delivery in a Large Health Organisation . The RAAAKERS™ framework (Responsibility, Authority, Accountability, Awareness, Knowledge, Experience, Resources and Systems) was used as an analysis tool to assist in understanding the main management stress points, and data was presented as a visual analysis . This work, co-authoured with Doctor Mark Burnett, will be published in the coming months in the Journal of Military and Veteran's Health . If you are in Singapore next week do look me up. Regards, Graham Happy Flu Network Diffusion ExperimentMatthieu Latapy is a network researcher at the National Centre for Scientific Research (Centre National de la Recherche Scientifique) in France. He is doing network research to counter peer-to-peer paedophile content - something I think we would all agree is very worthwhile! Matthieu is conducting an experiment aimed at understanding how a real-world spreading phenomenon occurs via links between websites. In particular he notes that information diffusion is increasingly orchestrated by bloggers instead of the mainstream media. Matthieu's experiment takes the form of a viral marketing approach - hence the name Happy Flu.

An Introduction to Network Analysis as a Research TechniqueFrom time to time I run a half-day seminar called “Introducing Network Analysis as a Research Technique ”, followed by a practical workshop that builds on the mornings activities and introduces participants to UCINET and NetDraw .
Network Analysis Seminar and WorkshopOn Friday the 4th of July 2008 I am once again running a half-day seminar called “Introducing Network Analysis as a Research Technique ”. This time the seminar will be followed in the afternoon by a practical workshop that builds on the mornings activities and introduces participants to UCINET and NetDraw .
The seminar and workshop are part of Canberra University’s Inter-University Research Workshop Program , and are aimed at new researchers. The workshop is also of use to anyone interested in network analysis, but is aimed at absolute beginners. Both the seminar and workshop are offered free of charge to research students and researchers from all institutions, but priority access will be given to students and staff from participating universities. Costs may apply to other participants. If you are interested and you are in Canberra on Friday the 4th of July 2008 you can register here . Further details about the seminar and workshop are below. ... The Six Knows Model and Visual ThinkingA simple model which I find useful is the “Six Knows Knowledge Model ” shown below. The model has its origins in the Rudyard Kipling poem “I Keep Six Honest Serving-Men ” , but no doubt I will be challenged on this assertion! That said it is a model that serves me well, except I would add ‘know how much’ as a node.
Now Dan Roam , quite independently of me, has enhanced the usefulness of the model by introducing a visual thinking element to it - he's also picked up on the how much dimension. Have a look at this presentation , but in particular slide seven (the preceding slides give some background and explanation). What I really like is the ability to add some discipline and consistency to my mind-mapping and rich pictures. ... Understanding the Complexity of a Program of Projects

Visualising Project Programme Risk?Today I thought I would share with you two new diagrams from my doctorate, because I am actually not so sure about their utility, and would welcome any feedback you might have. That said I do feel they elicit interesting management questions. Consider the network diagram below. For a change it’s a different organisation to the one we have been looking at in previous blog-posts , but I have applied the same principles. The graph shows a programme of projects, all of which are dependent on one another for one reason or another. For example a project building an electricity distribution grid in a new town might be critically dependent on a project that is building a dam that will produce hydro-electricity.
The circles are projects coloured and grouped by business unit. This organisation assigns risk to six categories, which are shown as the red squares. The categories are real things in the real world rather than budget and schedule. ... Is Knowledge Representation Becoming More Visual?
The first attempts to represent knowledge were probably pictorial, and can be seen in the elegant cave paintings of our ancestors. Indeed some of these are still maintained by indigenous people today – see for example the Aboriginal rock art of the Gagudju people of Northern Australia, one of the oldest cultures on the planet. Numerals and text soon followed and have been the mainstay of knowledge representation for at least the last 6,000 years. But is this changing? ...

The great enemy of clear language is insincerity. When there is a gap between one's real and one's declared aims, one turns as it were instinctively to long words and exhausted idioms, like a cuttlefish spurting out ink. |
