A Fra Mauro kind of week

Fra Mauro was a cartographer. He lived in the Republic of Venice in the fifteenth century.

I found out about him in James Cowan’s (1997) A Mapmaker’s Dream. In that account, Fra Mauro welcomed visitors from all over the world in his monastery and used their news to develop his map of the world.

I loved the idea that he could be in Venice and yet be connected with voyages of discovery and established trade routes.

I had a Fra Mauro feeling this week in rural New South Wales. Social media, particularly Twitter, brought me news of adventures elsewhere.

Jacquie Tran was on her way to a Sports Performance Research Institute New Zealand conference:

Javier Fernandez was at a conference:

Mark Upton was writing about returning ‘home’ in South Australia after all his travels. In his discussion of living in fellowship he wrote “We DO need to balance and share power by exploring the dynamic interaction of leadership and followship” (original emphasis).

By serendipity, I met Jo Gibson, who lives just 50 kms away. Jo is researching leadership and followership in the dynamic way that Mark advocates. I have the good fortune to be her PhD supervisor.

I ended my week, delighted in reading a quote from Albert Mundet far away in Spain: “We compete in the short term, but we may cooperate at longer term”.

From a Fra Mauro perspective, this sharing is immensely powerful.

For many years, I have hoped that open sharing is the new competitive edge and that through sharing we transform sport in the ways that about which Mark Upton and his colleagues write so eloquently and has been demonstrated so well in New Zealand and Spain this week.

#EL30 Graphing

Week 3 of Stephen Downes’ E-Learning 3.0 course is looking at Graphs.

Stephen recommended some resources for this topic. These included:

Vaidehi Joshi’s (2017) gentle introduction to graph theory. In her discussion of graphs, Vaidehi observes “in mathematics, graphs are a way to formally represent a network, which is basically just a collection of objects that are all interconnected”.  She distinguishes between directed graphs and undirected graphs and explains the ways edges connect nodes in these kind of graphs. An example of the former is Twitter (each edge created represents a one-way relationship), and of the latter Facebook (its edges are unordered pairs).

Vaidehi suggests a number of resources to provide details about graphs, one of them is Jonathan Cohen’s slide show Graph Traversal. He defines a graph as a “general structure for representing positions with an arbitrary connectivity structure” that has a collection of vertices (nodes) and edges (arcs). An edge connects two vertices and makes them adjacent.

A second resource shared by Stephen is Fjodor Van Veen’s (2016) Neural Network Zoo. In his post Fjodor shares a “mostly complete chart of Neural Networks’ and includes a detailed list of references to support his visualisation of the networks.

A third resource continues the visualisation theme. Vishakha Jha (2017) uses this diagram to inform the discussion of machine learning:

A fourth resource recommendation is Graph Data Structure and Algorithms (2017). This article aggregates a large number of links to graph topics. It includes this explanation:

One of the E-Learning 3.0 course members, Aras Bozkurt, exemplified this theme in this tweet and in doing so underscored the skills available within self-organising networks :

It was a great way to end and start conversations about graphs.

Australian Paralympic History Project: October 2018 Workshop

The Australian Paralympic History Project held a workshop in Sydney on the weekend of 27 and 28 October.

Tony Naar shared news of the workshop on the Project’s Facebook page (link).

Seven people attended the workshop. The project team were delighted to welcome a new member, Cecelia Hutchinson-Parsons. Cecelia came to the workshop after a week of volunteering at the Invictus Games in Sydney.

Cecelia created a Wikipedia article about the Iceroos (link) and helped update the 2018 Invictus Games article.

The APC’s CEO Lynne Anderson visited the workshop as did the APC’s  Communications General Manager Tim Mannion. They met the workshop organiser, Tony Naar and Cecilia, as well as Ross Mallett, Greg Blood, Gary Osmond and Patricia Ollerenshaw.

Patricia is working on articles about the 2000 Paralympics at the moment.

Tony noted of the workshop:

Creating and updating Wikipedia articles about Australian Paralympic sport relies almost exclusively on a handful of volunteers, who do an incredible job. As a result of discussions on the weekend, we have decided that we will now pursue a ‘small scale’ approach of catch-ups in the cities where we have active editors and seek to expand these groups by individual contact and one-on-one support.

He added:

We desperately need to expand the core group of contributors to maintain this unbelievable project.

I do try to keep an eye on this project. It has made an enormous impact on the open sharing of Paralympic stories with an Australian focus. I do monitor the articles and hope to be more active in supporting the editing of the articles created and maintained by the project team.

For anyone thinking of finding ways to use their creative talents, this is a project most worthy of consideration.
