(g^2)^7 - how not to be a maths teacher on camera.

"Turn Your Talent to Teaching"- but make sure they bloody camera-man doesn't catch you writing the wrong answers on the board.


The UK Government, once again wasting our money, is advertising for teachers. Maths teachers. Just a shame the editors included this bit in the still above.[1] Perhaps those useless maths classes at school weren't so useless. At least if you're in media/advertising.

The video, while it's still around (the `still' is from around 19s):
Teacher: What I want you do now is we're[2] going to look at how we're going to solve this equation here.[(g2)7=g? appears on the board as a problem]

Teacher's voiceover: If it's an early lesson and I need to get them started, [we see the kids playing bingo] I try different ways to clear the cobwebs out. [teacher writes g2×g7 on the board]


Teacher: This one, is just do[2] the highest common factor, so what's the highest common factor of 80 and 60.

Kids: <mumbles of 'twenty'>

Teacher: Do'ya[2] think it's twenty? Twenty, yeah?

One Kid: Bingo!

Other kids: <cheers>

Voiceover: Turn your talent to teaching. Visit teach.gov.uk

The Daily Mail appears to have been the first paper out with this 'mistake' being spotted by some 15yr old spotty oik[3] claiming they're showing the wrong answer.

Of course, that segment could quite probably have lasted a couple of minutes in the classroom there, with the teacher pointing out why it's not the right solution, but to include it in the final advert where it could be misinterpreted? Laziness on the behalf of the advertisers.

Of course, the DM's on a rant about how this 'wrong' answer shows declining standards in our schools. I'm more put out by the standard of spoken English by the teacher[2].


Mr. Coombs is praised highly for his observation of course. From the DM article:
Adam Williams, principal of John Cabot Academy which Chris attends, praised the schoolboy's attention to detail.
Aren't you simply looking forward him being one of your colleagues a few years hence? No big-headedness of course, just a mention in a newspaper article.
He said: 'It is great to think that Chris showed that degree of observation and understanding of maths to spot the apparent error in the advert.'
I learnt about indices in the first year of secondary school (12 yrs old) - just when are they teaching them these days? A-levels?



[1] For those who can't spot it, (g2)7, is g2×g2×g2×g2×g2×g2×g2 which is g14. Not g2×g7 which is g9. And Wrong™

[2] Probably just as well she's not teaching English.

[3] Well - Chris Coombs doesn't look too spotty from the DM photo.

Powerade ION4 - making you wetter than a wet thing in lots of wet stuff.

Prompted by STONESTREEKER:


Update: Jan 2014, ASA found against GlaxoSmithKline UK Ltd when they made a similar claim of "hydrates and fuels you better than water" finding that it "did not appear on the list of authorised health claims in respect of carbohydrate-electrolyte drinks"

Update: Jan 2012, ASA found in favour of Coca-Cola when two people make complaints about this advertising campain.



New, improved[1], Powerade ION4 [Subs: Na, Ca, Mg, K] [Sub: Contains carbohydrates] replenishes fuel and 4 of the minerals lost in sweat.

[Sub: Preparation]

[Sub: Determination]

[Sub: Perspiration]

[Sub: Hydration]

Powerade ION4, hydrates better than water.

Keep sweating.

Presenting Coca-Cola's new and improved[1] sports drink. They'll be sponsoring the Olympics (2012) dontcha know.

However it's not exactly new[1]. From the US website[current - there's a video there that didn't make it to the archive]:

In 2009, POWERADE® sports scientists created ION4®, which revolutionized the sports drink. ION4® is an advanced electrolyte system that is in POWERADE® to help replenish four electrolytes lost in sweat.

I wouldn't call a 2 year old product "new." Certainly not in the context of advertising. So that's a load of bollocks right from the start.



Back to the UK advert, they claim to "hydrate better than water." Sounds a tad spurious. Lets look at what it's supposed to 'help' with, or mitigate - dehydration.

The medical definition of dehydration (or hypohydration) is:

[...] the loss of water and salts essential for normal body function.

There are various stages/severity of dehydration:
Mild dehydration is the loss of no more than 5% of the body's fluid. Loss of 5-10% is considered moderate dehydration. Severe dehydration (loss of 10-15% of body fluids) is a life-threatening condition that requires immediate medical care.
Causes of dehydration?
Strenuous activity, excessive sweating, high fever, and prolonged vomiting or diarrhea
Symptoms?
Symptoms of dehydration at any age include cracked lips, dry or sticky mouth, lethargy, and sunken eyes. A person who is dehydrated cries without shedding tears and does not urinate very often. The skin is less elastic than it should be and is slow to return to its normal position after being pinched.
Treatment?
Increased fluid intake and replacement of lost electrolytes are usually sufficient to restore fluid balances in patients who are mildly or moderately dehydrated. For individuals who are mildly dehydrated, just drinking plain water may be all the treatment that is needed. Adults who need to replace lost electrolytes may drink sports beverages or consume a little additional salt.


So. Yes. If you're MILDLY dehydrated, Powerade, MAY be used to replace some salts lost during heavy sweating during exercise. (If you've lost quite a bit of fluid/your electrolyte balance is way off however I'd suggest you visit a doctor/hospital rather than drink this as a treatement.)

Or you could just drink water and, possibly, eat a packet of salt and vinegar crisps. Doing both, of course will also "hydrate you better than water (alone.)"

I think I know which will probably be cheaper. (I can't find any ION4 online at the moment, but from Ocado, 4x500ml bottles Powerade Cherry: £3.49. 12x25g Walker's Ready Salted: £2.65)

So while their claim to "hydrate better than water" isn't entirely bollocks, the way they present it - as something wonderful that cannot be achieved by anything else - is.

On the specific salts/minerals they mention - your body is adaptable. It can get temporarily lower on them without danger and can obtain all sorts of vitamins and minerals and salts from your (hopefully varied) diet. If you get a little low on some of them, your body will catch up. If you're getting dangerously low on some of them then Powerade isn't going to help you.

I'll probably do a post on the snake-oil that are OTC, self medicated, mineral supplements in general (or some specific ones) sometime.



[1] Come now. It can't be both. If it's new, then there isn't an old thing to improve upon. If it's improved then there must have been an older thing. Or as one Yahoo Answerer succinctly put it:
It's improving on the perfectly good thing that you own that the ad agency wants you to now think of as junk, so you'll buy the product they are pitching.

"For God's sake" is not offensive.

In the ongoing campaign by various groups about the invasive nature of, and pointlessness that is the UK Census being held this year, one group - the British Humanist Association[1] came up with three posters addressing what is the only voluntary question on the whole census - the religion question. One is shown below; all three can be seen here.
Not Religious?
In the 2011 Census Tick "No Religion"

"I put 'Jedi' in the last census. But I'll tick 'No religion this time.

I'm not religious and I don't want Bishops and the government saying this is a religious country.

That's just an excuse to keep religion in politics."

If you're not religious for God's sake say so.

cencus-campaign.org.uk


The intention was to buy advertising space at railway stations to display the posters

CBS Outdoor, the advertisers that own the space, had other ideas.

Two reasons were given by owners of the space: they were concerned that the use of the phrase ‘for God’s sake’ would cause widespread and serious offence and they also did not wish to take adverts relating to religion.

As the BHA allude to, only the professionally offended could take "widespread and serious offence,"

But what the BHA didn't point out (at least in their PR) is that the second reason is also spurious. Lots of religious groups are quite capable, and able, to advertise on the self-same spots. Those listed (though probably not exhaustive) include the Alpha course, the Christian Party[1] and the Trinitarian Bible Society.

It's not as if there isn't a history of religious advertising on public transport.

Vaguely related, I was somewhat amused by His Grace's "Mind your own *%$#@!! business" campaign but I think I'll be ticking the No Religion box.




[1] The BHA were responsible for the "There's probably no God. Now stop worrying and enjoy your life" bus adverts that generated ASA complaints. In reply the Christian Party came up with "There definitely is a God. So join the Christian Party and enjoy your life" which became the most complained-about non-broadcast ad ever.

Update (2): Natwest - (not so) helpful banking

Back in August '10 I brought up Natwest's "Helpful Banking." advert.
In December '10, they got slapped down by the ASA for not opening as many branches on Saturdays as they appeared to imply in that advert.


Now it appears that they aren't really living up to the rest of that advert.

Deloitte (an auditor) was hired by Natwest to monitor them for how well they were living up to their 'promises.'

A sample[current] of what they promised to do:

3. We will provide you with friendly, helpful service whenever you deal with us
We're aiming to get 9 out of 10 customers to rate our service as helpful.
90% satisfaction? Wonder how they're going to select the people they're going to question.

Either that or the fact that the other 10% of their customers are costing RBS/Natwest £2.8m due to mishandling of complaints in the space of 6 months[1] suggests that when things go wrong, customers would be better off at Santander.

9. We pledge to stay open for business if we are the last bank in town and will consider a range of options to ensure a local banking service is available
We’ve already identified over 100 ‘Last in Town’ locations where we’ll continue to provide a local banking service.
Woolly description of what "last in town" means, especially when by the industry definition, Natwest is already the "last bank in town" in 217 locations. I somehow thing it's stretching the weasle phrase "over 100" to cover 217, so that means they're quite able to shut "up to" 116 branches and still keep this 'promise.'

"Local banking service" is also similarly woolly. It's not a hard and fast commitment to actually operate a brick-and-mortar branch (Saturdays or not.) Perhaps they're going to buy some more white vans.

13. Twice a year we will publish the most common of complaints
And we’ll strive to address the causes

It's been 7 months since the adverts. I could be wrong, but if you're going to do something twice a year, it's generally accepted that they should be 6 months apart, so that mean they should have published at least one list.

Strangely I've not seen it, and it's certainly not linked on that page.


Anyway. How did they do?
(I couldn't find the report/PR, so this is based on the sparse news reports currently out there.)

Out of their 25 goals, they passed 20, and failed 5. That's 20% failure.  (Or a "80% success rate" as Brian Hartzer, head of Retail Banking, would have you think of it.)

Possibly an acceptable result had the goals been externally imposed, but these were self-imposed.


2. We will aim to serve the majority of customers within 5 minutes in our branches
This year we’ll introduce a new queue busting programme in our busiest branches to ensure every available member of staff is out serving customers during busy periods.

75% of customers were served in under 5 minutes. Presumably leaving the other 25% waiting half and hour. Or more.

3. We will provide you with friendly, helpful service whenever you deal with us
We're aiming to get 9 out of 10 customers to rate our service as helpful.

Only 80% of customers believed the hype. The still suspiciously high number is probably down to either judicious selection of the people questioned, or biased questioning. Again - few details available.

4. We will help you to make the right choices for you and your money, providing a clear product range with simply explained features and charges
All of our branch literature will be simplified and rewritten in line with customer feedback. We’re also introducing a new Customer Service Review programme to make it easier for our customers to choose the right product for them.

This appears to be another one. Bugger all detail apart from they've reduced the number of products from 600 before the banking crisis to 200 now.

12. We will resolve customer complaints fairly, consistently, and promptly
We are aiming for 75% of customers to be satisfied with the way their complaint has been handled.
Way short. 57%. And that includes a 41% increase in complaints about the group in the 2nd half of 2010. Perhaps RBS/Natwest were encouraging more people to complain so they could (attempt to) satisfactorily solve them to push the %age up?


Sadly none of the news reports coming up on Google News at the moment have the 5th missed target. Indeed, none of them list the four I list above in much detail.



[1] Ok, it was the first half of 2009, but the timing of the fine coinciding with this report from Deloitte is rather embarrassing.
