Delegation - A Story of Flagpoles


One of the most important functions of a manager is to facilitate the so-called process of delegation - this is defined and discussed in the online resource “Management Study Guide” at 


“A manger alone cannot perform all the tasks assigned to him. In order to meet the targets, the manager should delegate authority. Delegation of authority means division of authority and powers downwards to the subordinate. Delegation is about entrusting someone else to do parts of your job. Delegation of authority can be defined as sub division and sub allocation of powers to the subordinates in order to achieve effective results”.

Despite the simplicity of the concept of delegation, it is one of the most difficult management functions to balance effectively.

The two extremes of management style are:
  1. The micro manger – he or she does not delegate and prefers to perform all the tasks personally. This can be a sign of distrust in the ability of the subordinates. By using much of the available time in performing subordinate’s work, the micro manager does not give enough attention to the big picture that can languish as a result. 
  2. The hands-off manger – he or she is interested only in the big picture and is not greatly concerned with supervision of the subordinates work. The quality of this will often suffer as a consequence.
Most managers fall somewhere in between and it is one of the most difficult tasks to find the right balance – a balance that will vary in each type of corporation.   

I learned a very valuable lesson on delegation when I was in the military – we were performing aptitude tests for officer potential and one of the problems we were given went like this:

Task: You are to erect a flagpole 100 feet high.
Personnel: You have at your disposal a platoon– 1 sergeant, 3 corporals and 3 sections of soldiers, 10 in each section.
Equipment: There are three lengths of rope provided, each of which is 200 feet in length. The rope cannot be further subdivided. You also have 3 sledgehammers and 3 steel pegs, each two feet long.
Describe how you would erect the flagpole.

My solution was probably the most common one suggested from individuals in the group. 

“After tying the three lengths of rope to the top of the flagpole, each section of men, under supervision of the corporals, then marches outwards to form an equilateral triangle – with the flagpole at the centre. The sergeant would then supervise the hoisting of the pole and driving the pegs into the ground at the right positions.

Several other methods were suggested, all containing various degrees of complexity and practicality, but none described the solution the Army was actually looking for - which was simply this. 

You issue the following order  – “Sergeant, have the men erect the flagpole”.


This is a perfect example of delegation. To attain the rank of Sergeant in the Australian Army, you have to be a very capable and practical individual, well able to solve problems of the flagpole type. The Sergeant can therefore be entrusted with the task, leaving you, as the officer, free to engage in other work.

This principle can be carried across to all corporations, but if you can’t trust your subordinates, it can mean that there are problems in the recruitment or promotion system within your organisation. Or it can mean, that as a manager, you will have to learn to trust others – one of the most important assets of leadership, both in the military and in civilian life.

Rain on Your Wedding Day


Over recent years outdoor weddings have become increasingly popular, and events held by the sea or on mountain peaks for example, can provide spectacular backdrops for that very special day. However it also means that the weather becomes a major factor in the equation and this is often a difficult issue.

Outdoor wedding ceremonies are subject to the vagaries of the weather. (Image from Wikipedia Commons)


The fundamental weather problem emerges in the early stages of planning – weddings are normally organised several months ahead, but reliable forecasts for a given location ore normally only possible out to a week ahead. This mismatch of time intervals often causes substantial grief both to the wedding organisers and to the meteorologist who is called on to produce the weather forecast for the ceremony. 

Many of my numerous grey hairs have been produced from wrestling with this problem and I’ve found that one of the most dangerous life-forms in the jungle is a wet bride with her wedding dress trailing in un-forecast mud.

So are there ways around this dilemma? Well firstly, planning should take into account the long term climate averages – these can readily be obtained online and will give you some idea which are the wettest, driest, coldest and hottest months in your area of interest. However the problem with this is that on any particular day, average conditions are not always encountered. Remember Mark Twain’s observation – “Climate is what we expect, weather is what we get”.

Secondly, and most importantly, always have a plan “B” ready to go.
This simply involves organising access to a shelter nearby should rain develop on the day. This will take a lot or stress out of the decision-making and also off the meteorologist who is sweating this out with you.

Outdoor wedding ceremonies were practiced over many centuries across different cultures. This contemporary painting shows the wedding of the great Mughal Emperor Shah Jahan, circa 1630. Fireworks accompanied the ceremony throughout the night. (Image from Wikipedia Commons)

Then thirdly, start watching the weather forecasts 7 days out from the wedding – monitor these on a day to day basis and this will help you “fine tune” your arrangements. The forecasts tend to become more accurate the closer we get to the actual day.

Finally, I always fall back on my last defence which is the old belief, common to many cultures, that it is good luck if it rains on your wedding day. This relates to the association that rain has with the fertility of trees and plants, and the refreshing effect it has on the atmosphere.

In Hindu tradition rain is good fortune because a wet knot - the knot of marriage - is harder to undo than a dry knot. The Italians, have a wonderful saying “Sposa Bagnata, Sposa Fortunata,” which means “Wet Bride, Lucky Bride.” However many brides-to-be are not reassured by this knowledge.

Interestingly, in some parts of the world, it is law that the marriage ceremony must be performed under a roof, and this makes life a lot easier for the local meteorologists. If ever I run for Parliament that will be my main policy plank and, assuming I have the numbers, I’ll institute it immediately I become Prime Minister.

The Amazing François Viète


François Viète (1540 -1603) was one of the foremost mathematicians of the early Renaissance era.

Born into the French upper middle class, he became a lawyer by profession but his high intelligence allowed him to excel in several fields, including mathematics, astronomy and geography.

During the period when Spain and France were at war Viète broke the Spanish military code allowing the French to read secret dispatches. The Spanish King accused the French of using sorcery against him.

But it was in mathematics that Viète was to leave his greatest mark. Investigating methods of generating π, the ratio between the circumference of a circle to its radius, he discovered one of the classical formulae of mathematics that today is called Viète’s equation. It was one of the very early formulae involving infinite products and nested square roots.

                      .             2               .              2                  .....   =  π//2     
             √(2)              √(2+√(2))           √(2+√(2+√(2)))                         

Inspired by Viète I've been playing around with nested square roots over the last few years, and the results I've come up with are below. The 5th result contains a generalisation for pth roots, and the 6th is a generalisation of Viète's equation

No proofs are included but I thought the results themselves may be of some interest to a mathematician out there.

1.        If  x(n+1)=√(2+xn)  ,  x0=x, n=0,1,2,3…

            then xn=2cos((cos-1(x/2)/2n)) for |x|≤2
      
            and lim xn = 2.
                   n->∞

            Also, for x>2,

            xn=2cosh((cosh-1(x/2)/2n))

2.        If xn+1=√(2-xn)  ,  x0=x, |x|≤2, n=0,1,2,3…

           then xn=2cos(π//3+(-1/2)n (cos-1(x/2)- π//3))

           and lim xn = 1
                  n->∞

3.       If  xn+1= (√2/2)(√(2+xn)+√(2-xn))  ,  x0= x, |x|≤2, n=0,1,2,3…

          then xn=2cos(π//6+(-1/2)n (cos-1(x/2)- π//6))

          and lim xn = √3
                 n->∞

4.         1  .           1           .                1             ……….  =  √3      
           √2       √(2-√2))             √(2-√(2-√2)))                       2

5.      If xn+1 = {( xn+√ (xn2-4))/2}1/p + {(xn-√ (xn2-4))/2}1/p

         then xn=2cos((cos-1(x/2)/pn)) for |x|≤2, and

         xn=2cosh((cosh-1(x/2)/pn)) for x>2, 

6.                   .              2               .              2              ..   =  arcos(x/2)  
             √(2+x)      √(2+√(2+x))          √(2+√(2+√(2+x)))         (1-(x/2)2)
             
              for |x|<2

The 1948 London Olympic Games

Following the dark years of World War Two, when two successive Olympic Games were missed (1940 and 1944), a triumphant return was held with the London Olympic Games of 1948.  59 Nations participated but Germany and Japan, under Allied military occupation at the time, were not permitted to compete. The USSR chose not to do so.

That the games were held in London was a story in itself. Before the war the city had been selected to host the 1944 games but the war derailed this plan. The war had been over for nearly 3 years by 1948, but shortages of all types persisted in England, including food, petrol and accommodation and many were sceptical that London could successfully stage the Games.

However using much improvisation, the Organising Committee overcame all the problems. In marked contrast to the massive expenditure of recent Olympics, the London budget was miniscule. A special Olympic Village was deemed too expensive and instead, male athletes were housed in existing wartime RAF camps and female athletes in various London Colleges. As a result of these measures the 1948 Olympics became known as the “Austerity Games”.

On a sparkling summer day on 29th July, the Games were opened at Wembley Stadium before a crowd of 85,000 people and presided over by King George V1. The athletes paraded through the stadium, led by Greece and followed last of all by the athletes of the home country – the United Kingdom. And for the first time an Opening Ceremony was televised live and transmitted across the BBC network.

The Games concluded on 14th August 1948 and proved to be a resounding success. For the war weary world that participated they marked the start of an era of peace and general prosperity for the next decade.

Later this year London will become the first ever city to host the summer Olympics three times – in 1908, 1948 and 2012.

Olympic showcase:

One of the star athletes of the London Games of 1948 was the extraordinary Dutch athlete Fannie Blankers – Koen, who was then the mother of two children and competing at thirty years of age.

Nick-named the “Flying Housewife” she won four athletic gold medals at London – the 100 and 200 metre sprints, the 80 metre hurdles and was also a member of the victorious Dutch team in the 4x100 metre relay.

And along the way she proved several people wrong – before the games it was said that thirty was too old for elite athletics, and that anyway she should be home looking after her family. Remarkably it was later revealed that during her London triumphs she had been pregnant with her third child, eventually born in early 1949.

Blankers-Koen had competed in the 1936 Berlin Olympics as an 18 year old, and following London also competed at the Helsinki Olympics in 1952. She also ended up winning 58 national titles in Holland and was voted the “Female Athlete of the Century” by the International Association of Athletics Federations in 1999.

Her stellar career finally ended with her death in January 2004.

I'm A Barbie Girl

It’s no secret that pop music is big business, and a top 10 hit will normally rake in millions of dollars for the artists and record company concerned.

Because of these big dollars, legal issues sometimes arise that are fought out vigorously in court, with two famous examples involving allegations of plagiarism.

In the 1970’s a prolonged legal battle was fought over ex Beatle George Harrison’s song “My Sweet Lord” when it was alleged that this had been copied from the Chiffon’s 1963 hit “He’ So Fine”.

In 2009, it was alleged that part of the famous Australian hit “Land Down Under” had been taken from the 1930’s children’s song “Kookaburra”, and this too resulted in lengthy legal proceedings.

But probably the strangest legal case ever to arise from a pop tune was not fought over plagiarism but over a far more esoteric matter that those in the marketing world call “branding”. And it all came about like this.

With little doubt, the most successful toy doll ever made is the celebrated “Barbie Doll”, first launched by the American company Mattel, back in 1959. Through many years of clever marketing, the Barbie brand became immensely popular around the world, with a wide variety of Barbies made available together with a large range of clothes and accessories. Barbie also had a male companion called Ken and the entire arrangement was marketed as a sparkling and wholesome experience for young girls, typically in the age group from 3 to 12.

And the enormous success of the Barbie brand also attracted attention in other ways. In 1997, the Norwegian dance music group “Aqua”, working for MCA Records, put together a novelty song, “I’m a Barbie Girl”, which was a fun parody of a day in the life of Barbie and Ken. Accompanied by a catchy tune, music video and loaded up with raunchy double entendre lyrics, the song, against all expectations, rocketed up the charts, becoming a number 1 hit for three weeks in a row in both the UK and Australia. It also reached an unprecedented number 7 in the US Billboard Hot 100, thereby joining the big league of pop music and ultimately selling more than 8 million copies.

Nearly everyone was delighted but there was one major exception. Barbie’s maker Mattel was far from amused with what it claimed were undesirable images of Barbie and Ken that were promoted by the song and video clip.

Mattel alleged that the song portrayed Barbie as a sex object (referred to as “a blond bimbo girl” in the song) and that her image was tarnished by the inferences contained. These circumstances, Mattel believed, undermined the Barbie brand and devalued her commercial value. They likened MCA Records to a bank robber, piggybacking on Barbie’s fame to sell their record.

They filed a lawsuit against MCA, with the record company then countersuing for defamation over the “bank robber” inference.

The two cashed - up corporate heavyweights, both in a fighting mood and flexing plenty of legal muscle, commenced to slug it out through the US Court system. After lengthy proceedings Mattel’s claim was dismissed but an appeal was then launched in the US Supreme Court. In 2002, Judge Alex Kozinsky, perhaps showing signs of exasperation, again dismissed Mattel’s suit together with MCA’s countersuit for defamation, and at the same time advised both groups to “chill out”.

The whole fabulously expensive legal battle then ground down into a sort of bloodstained draw, ending what surely must be the only time a toymaker has sued a record company.  This strange case is a unique example of the law working in mysterious ways.

Aqua’s famous video clip of “I’m a Barbie Girl” can be seen here.


And in a strange twist to the tale, the following clip is a television advertisement for Fashionista Barbie, presumably approved by Mattel. The jingle seems strangely reminiscent of Aqua’s original tune that precipitated all the legal drama! But somehow I don't think anyone will sue.

Weather and Health

It has long been recognised that the weather can affect our general mood and feelings of well-being. Cabin fever is a well-known psychological condition arising from an extended period of inclement weather that forces people to remain indoors. Symptoms include irritability, forgetfulness, excessive sleeping, and in extreme cases, paranoia.

Prolonged spells of hot weather are often associated with a spike in human mortality, particularly for the very young, the very old or the ill, and it is believed that so called heat waves are responsible for more human deaths than the more spectacular weather events such as hurricanes, tornados and gales.

Increases in domestic violence also appear to cluster during hot spells, with irritability rising during these times. Increased consumption of alcohol may also be a factor here.

But it is also suspected that weather can influence our general health in a variety of other ways and this has proven a fascinating area of research since the mid nineteenth century.

An academic study was undertaken soon after the American Civil War by the eminent Philadelphian physician Dr. S. W. Mitchell who was interested in the effect of weather on war wounds and limb amputations. He observed that falling barometric pressure, together with rising temperature and humidity, frequently produced neuralgic pains in amputees.


Dr. Silas Weir Mitchell, c 1875

This observation was reinforced some 70 years later in an experiment performed by a German meteorologist Otto Hoflich. He correlated the pains experienced by a World War II soldier, Claus Thurkow, with the prevailing weather situation. Thurkow had lost his right arm during the War, and under instructions from Hoflich, kept a detailed diary on the dates and times when he experienced pain in the stump of his arm. The results were similar to Mitchell's conclusions regarding Civil War veterans.

It is believed that other conditions producing pain in the various joints of the human body, such as arthritis and gout, may also be weather sensitive, perhaps responding to changes in barometric pressure, temperature and humidity levels.

Perhaps the most surprising weather correlations that have been observed concern the beginning and cessation of life itself. Statistical correlations between the weather and coronary thrombosis (heart attack) have been demonstrated, usually involving conditions experienced with the approach of a cold front. Obviously weather is not the primary cause but perhaps the falling barometric pressure associated with an approaching cold front can trigger the onset of an attack in a person whose heart is critically poised because of disease.

Paradoxically, similar weather conditions appear to also precipitate the beginning of life with a statistically relevant correlation appearing between falling barometric pressure and the onset of spontaneous labour in childbirth. 

The onset of spontaneous labour in childbirth could be triggered by weather conditions.

Although the actual mechanisms involved in these situations are not understood, the statistics point to connections that demonstrate weather affects us in a whole variety of indirect ways. 

Perhaps in addition to the usual information, weather forecasts of the future will contain neuralgia advices, arthritis alerts and gynaecological warnings.

Young Griffo - Zephyr of the Ring

One of Australia’s earliest but least known world champions was the extraordinary Albert Griffiths, popularly known at the time as “Young Griffo”.

He was born in Millers Point, in Sydney’s Rocks district in 1871, and he lived and grew up in the immediate area. The Rocks in those days was not the pleasant historical locale so enjoyed by tourists today, but was a rough and dangerous neighbourhood, with general crime and street muggings commonplace, particularly after dark.

The notorious “Rocks Push”, a dangerous larrikin gang, ruled the streets by night, and fought with other local gangs such as the Argyle Cut Push, the Forty Thieves and the Straw Hat Push. These gangs had no compunction in knocking a passer by down and then “putting the boot in”, often seriously injuring or even killing the victim.

Henry Lawson, in his classic poem "The Captain of the Push"described something of the after-dark environment of "the Rocks" late in the 19th Century:

As the night was falling slowly down on city, town and bush, 
From a slum in Jones's Alley sloped the Captain of the Push; 
And he scowled towards the North, and he scowled towards the South, 
As he hooked his little finger in the corners of his mouth. 
Then his whistle, loud and shrill, woke the echoes of the `Rocks', 
And a dozen ghouls came sloping round the corners of the blocks. 

There was nought to rouse their anger; yet the oath that each one swore 
Seemed less fit for publication than the one that went before. 
For they spoke the gutter language with the easy flow that comes 
Only to the men whose childhood knew the brothels and the slums. 
Then they spat in turns, and halted; and the one that came behind, 
Spitting fiercely on the pavement, called on Heaven to strike him blind. 

It was in this rough and dangerous environment that Young Griffo grew up. As a youth he earned some money as a paper boy working the Rocks area, and to be successful he had to not only sell newspapers, but to defend his turf against bigger and older boys trying to muscle in on his corner. Despite his small height - only about five feet four - he was nuggety and powerful, and possessed amazing reflexes that gave him the ability to pick a fly out of the air without injuring it. The other older and larger boys learned to leave him alone or risk copping a beating.

It is not known whether he regularly attended school – being from the wrong side of the tracks in 1870’s Sydney probably meant not, and he was recorded as being completely illiterate and unable to count. 

He was eventually talked into becoming a prize fighter, and with some coaching, began to improve rapidly. He turned professional in 1886, and soon strung together an impressive series of wins in the featherweight division. He became Australian featherweight champion in 1888, and then in 1890, won the world championship when he beat titleholder Bill Murphy at the Sydney Amateur Gymnastic Club.

He then decided to head for the big money in the United States, finally arriving there in 1893, and began an unforgettable career there that would have many highs and lows. During this time he fought nearly all of the greats of his division and piled up an incredible record. Many of his fights were with men much heavier than himself, but he still won the vast majority of these.

His style in the ring fascinated the Americans. Although lacking a knockout punch he was a defensive genius and in an article in the Tacoma Daily News, later written in 1916, he was described thus:

“Not known as much of a puncher, but his skill was uncanny. He had wonderful headwork, almost impenetrable defence, dazzling feints, and rapid two-handed methods of attack. The cleverest boxers and hardest punchers were made to look ridiculous when exchanging swats with him.”

He amassed considerable prize money during this time, but his inability to count meant that he was short changed on occasion, with unscrupulous promoters giving him less than his entitlement. He was also generous and would often "shout the bar" after a win, going through his prize money in quick time.

And it was his drinking that was destined to later bring him down. He always preferred alcohol to training, and American whiskey proved to be a wonderful attraction. He began drinking heavily, and several of his important fights were performed when he was half drunk, but mostly he was still able to win despite his self imposed handicap.

As Demon Drink gradually took control he found himself increasingly in trouble with the law for being drunk and disorderly, and was locked up on several occasions.

After his last fight in 1904, and with his main income stream at an end, he became virtually destitute and took to begging on the steps of the Rialto Theatre, in New Yorks Time Square. He would also raise money in saloons by standing on a handkerchief and betting drinkers that they could not hit him even though he would not move his feet from the handkerchief. But as the years passed he was hit more often.

Young Griffo finally died in New York in 1927, at the age of fifty six, with the well known boxing promoter Tex Rickard generously paying for his funeral. Noted boxers from the past were in attendance, including the former heavy weight champion “Gentleman Jim” Corbett, who remarked as the coffin was carried out “ There he is boys, the Zephyr of all ring time. The only one that ever hit him was the Grim Reaper”. He was buried in the Bronx on that day.

The record he left behind was incredible. He lost just nine times in 232 fights, but with many of his bouts recorded as a “no contest”. However during this era a fight would be declared a “no contest” if the opponent was not knocked out, and in many of these Griffo was well ahead on points.

He was also a pioneer of he the practice, later made famous by the great Muhammad Ali, of nominating the number of rounds the fight would last before he emerged the victor.



Griffo was never defeated for either the world or Australian featherweight title.

In 1928 the founder of Ring Magazine, Nat Fleisher, wrote a book called “Young Griffo: the will o’wisp of the Roped Square” in which he noted that “Griffo was the greatest ever boxer I have seen in over fifty years of watching fights and fighters. His abilities to feint, move his head and not get hit were unparalleled”.

Fleischer also described Griffo as “the Shakespeare and Napoleon of his profession”, and “the fastest thinking, brainless boxer in the history of pugilism”. Fleischer ranked Griffo as number 8 in the all time featherweight division.

Mike Casey, the Boxing Journalist and Historian, writing for “East Side Boxing”, remarked that “Griffo seemed to drop straight out of some fistic heaven, and perhaps the gods were balancing the scales when they took him back at the age of fifty six. The mind boggles at what he could have achieved if he had been blessed with the mental toughness and the total commitment of a Julio Cesar Chavez or a Marco Antonio Barrera”.

Young Griffo was posthumously inducted into the Ring Boxing Hall of Fame in 1954, the International Boxing Hall of Fame in 1991 and the Australian National Boxing Hall of Fame in 2003. His citation for the International Boxing Hall of Fame can be read here:
http://www.ibhof.com/pages/about/inductees/oldtimer/griffo.html

(Note that this citation gives his date of birth as 1869, whereas most other sources quote 1871)

In an era when many bronze statues are sculpted for a variety of cricket and football stars from the past it would, I think, be a fitting tribute to erect one for Albert Griffiths, standing on a corner or in a park somewhere down in the Rocks. As Australia's first ever world boxing champion and arguably one of our greatest ever fighters, made all the more remarkable by his battle up through poverty and lack of education to get there, he deserves some formal recognition from our city fathers.

And surely a movie awaits for an interested producer.
