Performance Analysis Revisited 01

In 1998 I was invited to present at the Fourth World Congress of Notational Analysis in Porto, Portugal. I was in the process of clarifying my understanding of notational analysis at that time and was exploring some ideas in narrative structure stimulated by Donald Polkinghorne’s Narrative Knowing and Human Sciences and Elliot Eisner‘s approaches to educational research.

The talk in Porto gave me the opportunity to share and develop these ideas. I regret that I was unable to present in Portuguese at that time or now. My hope was that the presentation would stimulate discussion about a vision for performance analysis. I think that was overly ambitious for a conference in Porto where many of the attendees had come to learn about analysing specific aspects of performance in sport. I do think that the ideas I presented have direct relevance to discussions today about performance analysis and how analysis is constructed and shared with coaches and athletes.

The emergence of SlideShare and the potential to add Slidecasts has been prompting me to think about sharing these ideas with those interested in performance analysis in sport. Throughout my career I have tended to share my ideas with audiences other than those in peer review journals. SlideShare has created an opportunity for a public sharing of these ideas.

I have embedded the presentation here in this blog post directly from SlideShare. I created the audio for the Slidecast with Audacity and then used Internet Archive to store the MP3 file and create a url for the Slidecast.

The written proceedings of the Fourth World Congress were published in 2001 (Hughes, M.D. and Tavares, F. (eds.) Notational Analysis of Sport – IV, Cardiff: UWIC).

Wellbeing and Demographic Snapshots of Australia 2009

dscf0156

In the last week, two reports have provided some fascinating demographic information about Australia. An ABC news post drew attention to the most recent Australian Unity Wellbeing Index report developed in the Australian Centre on Quality of Life (ACQOL) by Bob Cummins. The Index has the aim of promoting greater public and political awareness of the social factors underpinning wellbeing, as well as enhancing scientific understanding of subjective wellbeing.

Results (Report 19.1) indicate that:

  • The five Statistical Sub-Divisions (SSDs) with the highest levels of wellbeing are all characterised by being fairly remote regions of Australia.  These are: Glenelg (VIC), Upper South East (SA), Kangaroo Island/Yorke (SA), Litchfield Shire (NT), Barkly/Lower Top End (NT)
  • The five SSDs with the lowest levels of wellbeing are all charactrised as inner-city.  These are: Fairfield-Liverpool (NSW), South Canberra (ACT), Inner Sydney (NSW), Greater Dandenong City  (VIC), Campbelltown (NSW).
  • Various demographic variables alone and in combination can explain 25-30% of the variation in wellbeing between SSDs.  The strongest of these are wealth (positive), population density (negative), the percentage of homes where only English is spoken (positive) and the percentage of people not born in Australia (negative).
  • The strongest demographic factor in terms of explaining variation between SSDs appears to be the percentage of people not born in Australia.  However, the influence is minor where the proportion of New Australians remains below 40% of the total SSD population.  The vast majority of SSDs contain less than 40% New Australians.  However, the few SSDs that exceed this proportion have low average wellbeing.
  • The domains of wellbeing that appear most sensitive to these influences are relationships and community connection.
  • Wellbeing generally falls in cities with more than 40,000 inhabitants.

The foundation paper for the Index was published in 2003 (Google Scholar link to a PDF copy of the paper.)

The Australian Bureau of Statistics has released a Picture of the Nation. A post announcing its publication reports that the Picture “analyses information collected in the 2006 Census of Population and Housing. It incorporates information from previous censuses—in some instances going back as far as 1911. It presents stories about contemporary society and trends that affect the lives of Australian people. Drawing on the rich variety of topics covered by the census and looking across different geographic areas and population groups, this report showcases the many strengths of census data”.

Some key points abstracted by the ABS:

  • Australians are living longer with the proportion of older Australians (aged 65 and over) increasing from 4% in 1901 to 13% in 2006.
  • The proportion of children (aged under 15) declined from 35% in 1901 to 20% in 2006.
  • Generation X and Y are the most highly qualified generation, with one in four having a Bachelor Degree or above in 2006.
  • Between 2001 and 2006, Australia’s population increased by over one million people, with about half from overseas migration and half from natural increase.
  • Young Australians continue to leave rural areas. Over a quarter of people leaving country inland areas in 2006 were aged 15-24. The loss of young people makes it difficult to sustain population levels in these areas.

CULTURAL DIVERSITY

  • Almost half (44%) of all Australians were either born overseas or has at least one parent born overseas.
  • About one-third of Australia’s Indigenous population are living in Major Cities.
  • In 2006, Australia’s Greek and Croatian born population had the highest citizenship rates with 97% and 96% respectively. Japan born residents had the lowest citizenship rate with 15%.
  • Over 200 languages were spoken in Australian homes in 2006. The most common non-English languages were Italian (1.8%), Greek (1.4%), Cantonese (1.3%), Arabic (1.3%) and Mandarin (1.2%).

LIVING ARRANGEMENTS

  • The proportion of young couple families without children has remained constant over the last 20 years (14%). However fewer of these couples are getting married – 44% in 2006 compared with 75% in 1986.
  • In 2006 two-thirds of all people living in group households were aged between 15 and 34 years.
  • In 2006, one in 10 people in Australia were living alone, but half the population lived in a two parent family with children.
  • In 2006, 24,000 children lived with their grandparents, with no parent in the family.

COMMUNITY

  • In 2006, more women had volunteered than men and people born in Australia were more likely to volunteer than those born overseas (22% compared with 15%).
  • In 2006, 1.3 million people provided unpaid care for another child, who was not their own. Two thirds of these were women.
  • 4.4% of Australians needed daily assistance with core activities such as self-care, moving around or communicating, because of a long term health condition, a disability or old age.

EDUCATION

  • One in four Australians attended an educational institution in 2006.
  • There were 1.7 million primary school students and 1.3 million secondary school students in 2006: a 2% decline in the number of primary students and a 5% increase in the number of secondary students since 1996.
  • The number of Indigenous students attending primary school increased by 17% to 72,000 between 1996 and 2006. Over the same period, the number of Indigenous secondary students increased by 46% to 40,000.
  • The most common fields of study for people’s highest non-school qualification were Engineering and related technologies (21%) and Management and commerce (20%) of all people with non-school qualifications.

WORK

  • Labour force participation for women increased from 48% to 58% between 1986 and 2006. Over the same period the participation rate for men fell from 75% to 72%.
  • In 2006, more people worked very long hours than in 1986: 19% reported that they worked 49 hours or more per week, compared with 15% of all employed people in 1986.
  • 8 out of 10 people travelled to work by motor car on Census day 2006.

ECONOMIC RESOURCES

  • The family home is the main asset for many Australians: 70% of households owned their own home with or without a mortgage: a similar rate to the past 40 years.
  • In 2006, more than two thirds (67%) of people who were employed full-time in higher skill level occupations (which included managers and professionals) had higher incomes.

HOUSING

  • Between 1986 and 2006, the number of private dwellings in Australia increased by 45% (or 2.6 million dwellings), while the number of people living in private dwellings increased by substantially less at 28%.
  • The median weekly rent for public housing was $90.

Both publications appeared (or were discussed) close to Australia Day. This year’s Australian of the Year, Mick Dodson, has stimulated a very open debate about when Australia Day should be celebrated and what the Day should be called.

Footnote: On 5 March 2009 Radio National held a fascinating discussion about Australian population growth. This is a link to a podcast of the discussions between Philip Adams, Mark O’Connor and Barney Foran. This is the trail for the program:

This month the Federal Government will be issuing its draft legislation on an emissions trading scheme. At the same time, our population is growing faster than Indonesia’s, faster than the Asia-Pacific region’s and three times as fast as the average OECD countries. But, is it possible to cut our greenhouse gas emissions without taking into account our future population?

Food for Thought 2.1

dscf0429

I had hoped to add to my Food for Thought 1.1 post last week but events overtook me! I was thinking that by the time I reached Adrian Hill‘s blog I would have written a Food for Thought 1.4 post. Instead I am at week two in the Rs.

In this week in review, Ruth Demitroff posted about Blip.fm, Chief Justice John Roberts and Barack Obama’s Inauguration Address. In her post on the Address, Ruth links to a new York Times article by Stanley Fish. Ruth draws attention to text as parataxis and I think this has implications for how we write in our blogs.

Rodd Lucier posted about the inauguration too (as did Pierfranco Ravotto with links to YouTube, Lee Kolbert on the first digital presidential portrait and Lani Hall). In other posts this week Rodd discussed: online identity (and offered advice about security, see too Kristina Hoeppner’s post); pendulum swings in education and included a Teacher 2.0 podcast (see Nellie Muller‘s post along these lines); and concluded the week with a post about Creative Commons.

Rhondda had a busy week of posts. Early in the week she reviewed the Icerocket search engine. In her next post (It’s not about the technology) she observes that “In the past 12 months I have found an amazing world on-line, that offers me so much for my own professional learning, making me a better teacher and I hope that some of my posts/links have assisted others as well”. She then posted about Worldometers (world statistics updated in real time) and day later abour reading options and DailyLit. Rhondda’s week concluded with her post about useful links. All this whilst preparing for a new school term in Melbourne, Australia.

Pat Parslow’s most recent post was a position paper (with Shirley Williams and Karsten Oster Lundqvist) on the future of social networking.

Nellie Deutsch has been incredibly busy with the Digifolios and Personal Learning Spaces Ning site. Most recently she was involved in a Wiziq discussion about online identity (recording available at the Ning site).

This week the LibraryTechNZ Source post provided an update on digital libraries and library innovations from around the world. In the post

it is the smart and sensitive teacher, endlessly re-inventing her practice, noticing what works for individual kids, that makes the difference. Or the creative and flexible principal, willing to suspend the Big Expensive Program, guaranteed to yield (and I hate the way this word has been co-opted) results–in favor of something that meets the needs of real kids.

Milton Ramirez had a busy week of posts including teaching as an attractive and exciting career opportunity, the results of the PEW report, a discussion (inspired by a post by Doug Johnson) of the impact of books, blogs, articles and columns, three posts on Barack Obama, and a discussion of connectivism. Milton’s last post of the week introduced me to Sugar Labs. I hope to return to Sugar Labs soon!

Mike Gotta drew attention to a Web 0.0 paper from 1991 in his first post of the week. He followed this up with a discussion of the importance of Lotuspere 2009 and Lotus Connections and SharePoint.

Mike Bogle’s Techticker was a mine of information this week. He discussed free culture and Creative Commons and linked to Lawrence Lessig. (Melanie McBride posted about Lawrence Lesig this week too.) Mike’s post reports how he has created an audio archive of Lawrence’s four free culture presentations. Mike includes the workflow of how he did this.

… in the interests of transparency and respect for open source purists, I wanted to include the work flow process I used to ultimately produce the OGG version.  I relied upon as much open source software as I could (as always), however there are two notable exceptions that I’d like to menition. Namely, the process was conducted on Windows XP and included the MP4 codec during the initial rip from YouTube.

(See Mike’s discussion of Open Source this week for his take on sharing.)

Mike’s second post of the week was a slow blog about the Digital Youth Project and includes a video blog about his thoughts. Mike observes that “the results (of the project) point to a dynamic and complex ecosystem of interaction amongst young people that I believe we would do well to consider in discussions on elearning and new media – and in particular the manner with which education should seek to foster engagement and lifelong learning amidst young people.” His final post of the week discusses TOTLOL and children’s digital literacy.

In addition to her post about Lawrence Lessig, Melanie McBride shared news of her presentation at Web Weekend in Vancouver in February. Her talk, “Magazines2.0: The Sharing Revolution,” will consider existing and emergent issues related to the publisher and reader of web2.0 publications.

Matthias Melcher considered connectivist taxonomy this week. His post addresses the visualisation of a taxonomy in a very interesting way and he draws upon his native German landscape to to help him. He concludes that “the concept cluster of learning network/ ecology/ space is too overburdened and deserves some dissection.”

Lisa Lane discussed videoconferencing this week. She reflected on a Business Week article to develop her own use of videoconferencing. Mike Bogle commented on Lisa’s post and shared this link. Lisa responded with a discussion of Seesmic and its potential. (It was interesting to read Kristina Hoeppner’s post on the lens-eye after reading Lisa and Mike’s exchange.)

Lee Kolbert’s post this week took a close look at the potential of Nibipedia for teachers and students. She considers some of the access issues that might occur with some of the content and one of the creators of Nibipedia, Troy Peterson responds to Lee’s observations.  (Stephen Downes posted on Nibipedia too this week.)

Kristina Hoeppner posted three times this week. In her first post she discusses some of the issues raised by the availability of Userfly (a new online service which allows you to record a screencast of anybody who comes to your website) and the appearance of Tumbarumba. Her third post of the week reports the discovery of an apartment in Leipzig that was in an untouched condition from almost a decade before the fall of the Berlin Wall.

I was unable to access Konrad Glogowski‘s blog at the time of writing this summary.

Kevin Jones’ post this week reports on How Conferences Should Be Done and points to the Americorps Ning site.

I could not think of a better place to end my alphabet review this week with a visit to the busy week of Karyn Romeis and her learning journey. Her blog is “a catch-all for things that have caught my eye, links to helpful information and the odd soapbox moment”. Tuesday’s picture of the day was ‘Computer Hell‘ ( “Oh, for a techie to come and look over my shoulder and say, “Ah yes. I see what the problem is.” And then FIX it.”) (By Thursday the Articulate User Community had come to her rescue.) Karyn linked to Blurb in another of her posts and discussed the idea of publishing your own bespoke book.

There are 16 Js in my Nourishment list so I will draw breath here and hope that nature and workflow this week give me an opportunity to write Food for Thought 2.2. I am off to Sydney to celebrate our son‘s birthday. Somehow we have persuaded him that a trip to a Leonard Cohen concert is just what he needs!
