The battle for Arctic riches heats up

In recent posts I have identified the growing issues of declining energy reserves and those countries and firms seeking to protect their self-interests. Clearly, the oil industry is facing uncertain times, not just in terms of the declining reserves, but also in light of rapidly changing technologies and expectations in terms of the environment.

The state of oil production is beginning to cause alarm. Oil production peaked during 2006 with global oil production from mature oil fields now declining at a rate of between 6-7% per year. Oil is becoming more difficult, expensive and energy intensive to extract.  The Peak Oil Crisis website has real time clocks of global oil consumption and graphics illustrating the impending crisis as well as articles, graphics and links to industry articles. Countries reliant on oil imports are desperately seeking new oil and gas sources with global oil companies jockeying for position to extract any new reserves found. Power politics are coming to the fore and environmental organisations are increasingly concerned about the ramifications of the rush for oil on the global environment as multinational oil giants seek out previously untapped reserves in the remotest of regions.

Criterion D, is it an afterthought sometimes?

Filed under: Physical Education — Tags: , — Katrina @ 7:29 pm

I don’t know where the last few months have gone, but it has been busy times, as it always is at this time of year. The year is almost over and the end of year reports are on my mind. As I’m deciding on the final level for criterion D, questions come to mind on how this criterion will be considered at the next curriculum review for MYP PE, starting at the end of the year.

Discussing criterion D with a class yesterday, a girl rightly so asked what does it mean to ‘respect yourself?’ I was stumped. It is easy to elaborate on respecting others and your physical environment, but how can she show respect for herself in the basketball unit? A better question, how did I teach this over the six week unit? Then more questions came to mind on how I am actually planning to teach objective D and the realization set in that I have perhaps neglected this criterion. I had spent so much thought on how to develop their understanding of the game and development of the fundamentals that criterion D was an afterthought at the end of the unit.

The Growth of Online Workshops

Filed under: Supporting Learning Communities,Triple A Blogs — Tim Cunningham @ 12:30 pm

Triple A Learning is now in its 3rd year of providing IB-approved online professional development workshops. During that time, over 3000 MYP and DP teachers and administrators have taken one of our workshops leading to IB-recognized certification. The numbers of schools adding online workshops to their Professional Development portfolios appears to be growing each year. These schools see online workshops as a relatively low-cost yet very effective method of training their faculty.

Here’s a screenshot of a typical online workshop with Triple A Learning. Notice the use of 21st century learning tools – blogs, wikis, discussion forums, e-libraries and message boards.

How Psychology Can Inform Economics

Filed under: Psychology — Tags: , , , — Peter Anthony @ 5:57 am

As subject specialists we tend to focus on our own areas of expertise. Perhaps our students, who come into contact with a range of subjects each day, are better at seeing connections. Recently the The Economist hosted a debate on happiness by looking at the topic “This house believes that new measures of economic and social progress are needed for the 21st-century economy.”

On one side is Richard Layard who opening statement is that: “Surely the quality of life, as people experience it, has got to be a key measure of progress and a central objective for any government.”
Arguing against the motion is Paul Ormerod who claims that: “Government attempts to increase measured happiness, rather than making life better for us, may well actually do the opposite.”

Measuring Growth, Development and Happiness

Filed under: Economics — Tags: , , , , , — Peter Anthony @ 5:38 am

The Economist hosts debates on a range of topics relevant to the IB Economics Course. By following the debates or reading back over debates that have concluded students can gain a better idea of the contested issues in economics. In additions these debates highlight the difference between normative and positive statements. A recent debate on happiness looked at the topic “This house believes that new measures of economic and social progress are needed for the 21st-century economy.”

On one side is Richard Layard whose opening statement was that:

Essential Minerals – Zinc

Filed under: Chemistry — Tags: , , , , , — David @ 12:00 pm

The RDA (recommended daily amount) of Zinc for a typical adult is approx 10mg daily. It is present in most food but notable food with a high concentration of it include oysters, beef and sesame seeds.

It is used by the body in cellular respiration and there are approx 100 enzymes in the body that require zinc1. It also has roles in the enzymes involved in the immune system, protein synthesis and wound healing.

knowing the future: prophetic dreams

Filed under: TOK meets global citizenship — Tags: , , , , — Eileen Dombrowski @ 4:48 am

“Believing you have seen the future in a dream is surprisingly common,” writes Richard Wiseman, “with surveys suggesting that around a third of the population experience this phenomenon at some point.”  The topic of prediction and justifications for accepting versions of the future is a magnetic issue in TOK, running through a number of areas of knowledge (as I have commented in my previous two postings). In this extract from his recent book Paranormality, Wiseman raises a number of issues relevant to accepting dreams as giving us prophetic knowledge of the future.

Examining the justifications for believing that events we experience have been foretold in our dreams, Wiseman rejects them all for the following reasons:

Minerals in the body – Iron

Filed under: Chemistry — David @ 12:00 pm

Perhaps the most well known of the minerals in the body is iron. Iron proteins are found in all living organisms and the colour of our blood is due to hemoglobin, an iron containing protein.
