Research shows multi-tasking can take more time and result in more errors than does focusing on a single task at a time.

"We know that if you have a person attending to different things at
the same time, they're not going to retain as much information as they
would if they attended to that one thing," said Nathan Bowling, an
expert in workplace psychology at Wright State University in Dayton,
Ohio.

Yes I agree.  I think multi-tasking increase the chance of error which means you end up taking more time than if you just did one thing at a time.  I also think it leads to a poor professional perception.  There is no doubt you can tell when someone has sent an email from a Blackberry when say in meeting or on the phone.  Full of mistakes and just does not look good and professional.

Addicted ... emailing and texting during meetings is an office no-no 

And guys having "sent from my Blackberry" in your email signature is an indication to me that you have not taken time over the response and given the focus that I expect.    Does not impress me that you sent an email from you Blackberry at 10:00PM on Friday night.  Was most likely sent from a bar anyway.

Lots of economic data in the past week giving a good indication as to where the Australian economy is at.  Last week we saw the GDP numbers which showed that the economy grew by 0.4% in the March quarter, which was slightly higher than market expectations and means that Australia has technically avoided a recession which is defined as two quarters of negative economic growth in a row and is the economy of the developed economies  in the world that is growing.  However  if you look at the numbers the 0.4% growth was due to mainly a growth in exports on the back of a lower exchange rate, declining imports and increased consumer spending on the back of massive government stimulus including $900 payments to 90% of tax payers.

The problem is that 0.4%  economic growth is not enough to sustain demand for labor, which is why you are seeing increasing unemployment.  When I studied economics at university the rule of thumb was that you needed 3% economic growth to sustain demand for labor, especially when you have an increasing population and increasing migration.   Since November, the percentage of the workforce without a job or
wanting more work has risen from 11 per cent to 13.4 per cent, the
Bureau of Statistics reported yesterday.  The unemployment rate in Australia is at 5.7% up from 4% a year ago.  I think increasing unemployment is a better indication of a recession than GDP.  

The Australian economy has held up during the world recession.  In contrast, the US lost 4.5 million jobs since September 2008, Britain
203,000, Japan 560,000, while Canada - which with its solid banking
system and mineral wealth is often compared to Australia - has lost
360,000 jobs.  The reason for this is the strong demand for Australian resources especially from China, the strength of the Australian banking system and that the central bank had room to move on interest rates once the world recession hit, very low levels of government debt and the strength of the Australian economy going into the global recession. 

Note the sharp rise in Australian unemployment since late 2008... however has stabalised over recent months.

However we are not out the woods.  Measurements like business investment are down significantly and job ads are down 50% from a year ago which indicates 2009 and well into 2010 will be difficult times.
