Plastic surgery plastic surgery is the process of reconstructing or repairing parts of the body by the transfer of tissue either in the treatment of injury or for cosmetic reasons it can involve a number of different techniques to move and manipulate body tissue in the independent healthc care sector Aesthetic Surgery has increased
In popularity showing the increased consumer desire for it many people regard Aesthetic Surgery as a Panacea for the personal and relationship difficulties active and aggressive media which were almost absent 50 years ago have made our society ambitious and the media have globalized the perception of what is attractive desirable and
Sexy society’s current obsession with looks May reflect the modern image obsessed culture but it can also be due to entrenched insecurities in people’s psychological makeup in the past few years a lack of respect for ethical principles in plastic surgery has become increasingly noticeable as the the concepts of beauty
Undergo change wrinkles fat deposits and Sun damaged skin no longer fit into our concept of a neat Society now that these real or perceived aging problems receive greater attention from patients and doctors the ethical considerations also need to be focused upon enhancement versus therapy risks patient autonomy beneficence and
Informed consent are issues that need to be reconsidered and emphasized when considering Aesthetic Surgery principles that could help guide Healthcare professionals include a respect for autonomy beneficence non-maleficence and Justice in general competent adults have the right to decide whether they wish to undergo a surgical procedure or not the
Patient wishes and thereby their right to an informed decision have to be taken into account provided they have been given sufficient information which must include the risks together with alternative options these principles apply even more to aesthetic operations where patients are not suffering from any illness these treatments which may lead to
Long-term adverse effects on body function and health involve serious ethical concerns in such situations the patient right for autonomy May contradict the physician’s principle of non-maleficence and therefore proper consideration is needed before deciding on such treatments surgeons must therefore ensure that the patient expectations are reasonable the beneficence principle
Requires that medical practitioners act in the best interests of patients undertaking surgery to improve a patient self-image and esteem is acceptable however defining the patient best interests can be very difficult many people are extremely self-conscious about their appearance and these groups May benefit from Aesthetic Surgery body dysmorphic disorder bdd is
A psychiatric syndrome characterized by a preoccupation with a non-existent or minimal cosmetic defect associated with persistent attempts to have the defect surgically corrected bdd is increasingly recognized and may be becoming more prevalent the principle of non-maleficence ensures that an aesthetic surgeon never acts against a patient’s welfare or in a way that may
Harm a patient consultant aesthetic surgeons May decline to operate on patients if they do not believe that the surgery is to the patient benefit aesthetic surgeons should be reluctant to operate on those with unrealistic expectations as the risks of surgery May outweigh any benefits patients with serous health
Problems are also at increased risk of complications under general anesthesia and again the risks May outweigh the benefits all such assessments need to be made on an individual basis in the past there has been a perception that surgeons have a potential conflict of interest in the independent sector no
Surgeon should ever proceed with an operation merely for personal pecuniary gain all aesthetic surgeons need to take the duty of care to their patients very seriously the Justice principle requires requires doctors to ensure that Medical Care is available to all Equitable Access to Health Care is regarded by many as a basic
Entitlement however resources are limited and it is not possible for any Health Service to provide Aesthetic Surgery for all those who would like it rationing takes place on the basis of clinical necessity inevitably this introduces subjective judgment about whose need is greater in the private sector those who can afford to pay undergo
Surgery requests for Aesthetic Surgery occur in all social classes however as stated earlier because of economic considerations there are no social systems in the world that covers Aesthetic Surgery except for some particular interventions the case of adolescence is especially problematic the deformity physical and emotional maturity and the desired outcome for each adolescent
Patient must be carefully evaluated before any decisions are made additional consultations and long discussions before Aesthetic Surgery are always necessary and this may require expert psychological assessment at present Aesthetic Surgery is passing through an identity crisis as well as posing an acute ethical dilemma a closer look from an ethical Viewpoint
Makes it evident that the doctor who offers aesthetic interventions faces many serious ethical problems to do with the identity of the surgeon as a Healer Aesthetic Surgery makes profit from the ideology of a society that serves only vanity youthfulness and personal success and one which is losing sight of the real
Values the real value of a person cannot be reduced to his her appearance and medicine as an art should feel the obligation to resist these modern ideologies and should attempt to help people get a more realistic attitude about themselves plastic surgeons must resist aesthetic measures in children and Adolescence particularly operations
Which are totally cosmetic nevertheless exceptions to exist and convincing arguments May support aesthetic measures with Children and adolescents to prevent stigmatization in selected cases however while this may be credible it cannot be a jellyfish a remarkable marine life form when viewed in the wild jellyfish are perhaps the most graceful
And vividly colored of all sea creatures but few people have seen a jellyfish living in its natural habitat instead they might see a dead and shapeless specimen lying on the beach or perhaps receive a painful sting while swimming so it is inevitable that jellyfish are often considered ugly and possibly
Dangerous this misunderstanding can be partly traced back to the 20th century when the use of massive Nets and mechanical winches often damaged the delicate jellyfish that scientists managed to recover as a result disappointingly little research was carried out into jellyfish as marine biologists took the easy option and focused on physically
Stronger species such as fish crabs and shrimp fortunately however new techniques are now being developed for example scientists have discovered that sound bounces harmlessly off jellyfish so in the Arctic and Norway researchers are using Sonar to monitor jellyfish beneath the ocean surface this together with Aeroplane surveys satellite imagery and underwater
Cameras has provided a wealth of new information in recent years scientists no believe that in shallow water alone there are at least 38 million tons of jellyfish and these creatures inhabit every type of marine habitat P including deep water furthermore jellyfish were once regarded as relatively solitary but
This is another area where science has evolved Dr Karen Hansen was the first to suggest that jellyfish are in fact the center of entire ecosystems as shrimp Lobster and fish shelter and feed among their tentacles this proposition has subsequently been conclusively proven by independent studies DNA sequencing and isotope
Analysis have provided further insights including the identification of numerous additional species of jellyfish unknown to science only a few years ago this brings us to the issue of climate change research studies around the world have recorded a massive growth in jellyfish populations in recent years and some scientists have linked this to climate
Change however while this may be credible it cannot be established with certainty as other factors might be involved related to this was the long-standing academic belief that jellyfish had no predators and therefore there was no natural process to limit their numbers how however observations made by Paul derer and his team showed
That this was incorrect as a result the scientific Community now recognizes that species including sharks tuna swordfish and some salmon all prey on jellyfish that evidence of just how sophisticated and unusual these life forms are it is still widely assumed that jellyfish are among the simplest life
Forms as they know brain or central nervous system while this is true we now know they possess senses that allow them to see feel and interact with their environment on subtle ways what is more an analysis of so-called upside down jellyfish shows that they shut down
Their bodies and rest in much the same way that humans do at night something once widely believed to be impossible for jellyfish furthermore far from floating in the water as they are still sometimes thought to do analysis has shown jellyfish to be the most economical swimmers in the animal
Kingdom in short scientific progress in recent years has shown that many of our established beliefs about jellyfish were inaccurate jellyfish though are not harmless their sting can cause a serious allergic reaction in some people and large outbreaks of them known as blooms can damage tourist businesses break fishing nets overwhelm fish farms and
Block industrial cooling pipes on the other hand jellyfish are a source of medical collagen used in surgery and wound dressings in addition a particular protein taken from jellyfish has been used in over 30,000 scientific studies of serious diseases such as Alzheimer’s thus our relationship with jellyfish is
Complex as there are a range of conflicting factors to consider jellyfish have existed more or less unchanged for at least 500 million years scientists recognize that over the planet’s history there have been three major Extinction events connected with changing environmental conditions together these destroyed 99% of all life
But jellyfish live through all three research in the Mediterranean Sea has now shown remarkably that in old age and on the point of death certain jellyfish are able to revert to an earlier physical state leading to the assertion that they are Immortal while this may not technically be true it is certainly
An extraordinary Discovery what is more the oceans today contain 30% more poisonous acid than they did 100 years ago causing problems for numerous species but not jellyfish which may even thrive in more acidic Waters jellyfish throughout their long history have shown themselves to be remarkably resilient
Studies of jellyfish in class no as cyoa have shown a life cycle of three distinct phases first thousands of babies known as PL are released then after a few days the pl develop into pops stationary life forms that feed off floating particles finally these are transformed into
Something that looks like a stack of pancakes Each of which is a tiny jellyfish it is now understood that all species of jellyfish go through similarly distinct stages of life this is further evidence of just how sophisticated and unusual these life forms are human distrust of robots that look
Like us we humans have evolved to relate emotionally to non-living objects which is strange when you think about it children play with dolls and toy soldiers as if they were people adults talk to their cars as long as they are robot-like and mechanical we are comfortable around them and can display
Affection as for an old car but when it comes to human-like robots something different happens as they become more human-like our affection disappears and we begin to feel less comfortable our liking turns to revulsion Androids that look too human freak us out B this odd phenomenon is called the canny Valley a
Term coined by robotics Professor MSI homori but the effect has particularly confused and puzzled engineers and scientists who design robots and interactive software the term comes from the Dip in a graph with two parameters affection and human likeness as human likeness increases so does our affection as soon as the resemblance becomes too
Great though affection drops below zero hence the valley the effect was highlighted by studies of machines such as the geminoid F robot created by Professor Hiroshi ishiguro of Kyoto University his robots have human-like bodies but their movements although impressively human-like show something of the mechanism beneath their skin and
People didn’t respond well to them making robots look human is a major goal of robotic engineers and scientific writers have long dreamt of Androids so The Uncanny Valley could potentially spell the end to their dream CV researchers have tried to find the cause of The Uncanny Valley one of the most
Interesting insights has come from an international team led by Ace penar San of the University of California San Diego UCSD San and her team conducted an experiment scanning the brains of 20 subjects aged 2036 while they were looking at three different things a human a mechanical looking robot and a
Humanlike robot interpreting the results from the fmri scans the researcher suggested that the C for the valley is a conflict in perception between two processes in the brain that of recognizing a human-like face and that of recognizing different kinds of movement T these processes or Pathways
Meet in an area of the brain called the parietal cortex there information from the visual cortex relating to bodily movement is integrated with information from the motor cortex that contains mirror neurons the brain cells that register that what we are seeing is one of us alarm Bells go off in the brain
When there is a conflict between the human-like features of the robot and its inhuman movement this mismatch creates a feeling of revulsion similar to what we feel when looking at a movie zombie we instinctively expect human-like creatures to have human-like movements as sent says the brain look see for its
Expectations to be met for appearance and motion to match e the discomfort we feel is not logical and has its roots in our evolutionary past researchers believe that the modern mind came into being between 60 and 40 years ago when Pathways in the brain became connected probably thanks to the evolution of
Language the way we understand our world and emerged from these new connections robotic Evolution challenges this mental software of ours The Uncanny Valley seems to represent the point at which logic stops and our instincts start to react F despite such studies many for for example mcdorman atal believe that
Cultural factors also contribute to the effect and researchers have pointed to the fact that young people who are used to technology seem less affected by the effect furthermore The Uncanny Valley effect has been observed in our response to still photographs of humans that have been altered slightly with Photoshop
Software even as far back as the 19th century the great naturalist Charles Darwin noticed that we react most adversely to species with eyes nose and mouth arranged like our own the phenomenon May therefore be more complex than Sean’s research suggests so is this the end of robots as we have dreamt them
Are our brains unable to cope with mechanical doubles perhaps not it may just be a temporary phenomenon the positive response to recent Androids shows that once the design and movements of robots become even more humanlike the affection graph rises again from The Uncanny Valley acceptability returns
Steeply to normal we seem to be at ease with Androids that have human bodies and human movements even if we know they are not human as we cross The Uncanny Valley another Basic Instinct comes into play empathy it is possible to mix human and mechanical characteristics without getting trapped in uncanny valley
Eventually human-like robots will make us love them too the case for mixed ability classes picture this scene it’s an English literature lesson in a UK school and the teacher has just read an extract from Shakespeare’s Romeo and Juliet with a class of 15-year-old he’s given some of the students copies
Of No Fear Shakespeare a kid-friendly translation of the original for three students even these literacy demands are Beyond them another girl simply can’t focus and he gives her pens and paper to draw with the teacher can ask the no fear group to identify the key characters and maybe provide a tentative
Plot summary he can ask most of the class about character development and five of them might be able to support their statements with textual evidence now two curious students are wondering whether Shakespeare Advocates living a life of moderation or one of passionate engagement as a teacher myself I think
My lesson would be going rather well if the discussion went as described above but wouldn’t this kind of class work better if there weren’t such a huge gap between the top and the bottom if we put all the kids who needed literacy support into one class and all the students who
Want to discuss the virtue of moderation into another the practice of streaming or tracking involves separating students into classes depending on their diagnosed levels of attainment at a macro level it requires the establishment of academically selective schools for the brightest students and comprehensive schools for the rest within schools it means selecting
Students into a stream of General ability or sets of subject specific ability the practice is intuitively appealing to almost every stakeholder I have heard the mixed ability model attacked by way of analogy a group hike the fittest in the group take the lead and set a Brisk Pace only to have to
Stop and wait every 20 minutes this is frustrating and their enthusiasm wains meanwhile the slowest ones are not only embarrassing but physically struggling to keep up what’s worse they never get a long enough break they honestly just want to quit hiking they feel is not for them mixed ability classes bore students
Frustrate parents and bum out teachers the brightest Ones Will Never Summit Mount kangma and the stragglers won’t enjoy the lovely stroll in the park they are perhaps more suited to individuals suffer at the demands of the collective mediocrity prevails so is learning like hiking the current pedagogical Paradigm
Is arguably that of constructivism which emerged out of the work of psychologist Lev vigotsky in the 1930s vigotsky emphasized the importance of targeting a student specific zone of proximal development Z this is the gap between what they can achieve only with support teachers textbooks worked examples
Parents and so on and what they can achieve independently the purpose of teaching is to provide and then gradually remove this scaffolding until they are autonomous if we accept this model it follows that streaming students with similar zpds would be an efficient and effective solution and that forcing
Everyone on the same hike regardless of aptitude would be Madness despite all this there is limited empirical evidence to suggest that streaming results in better outcomes for students professor John Hattie director of the Melbourne education Research Institute notes that tracking has minimal effects on learning outcomes what is more streaming appears
To significantly and negatively affect those students assigned to the lowest sets these students tend to have much higher representation of low socioeconomic class less significant is the small benefit for those lucky clever students in the higher sets the overall result is that the Smart Stay smart and the dumb get Dumber further entrenching
The social divide in the latest update of Hattie’s influential meta analysis of factors influencing student achievement one of the most significant factors is the teachers estimate of achievement streaming students by diagnosed achievement automatically limits what the teacher feels the student is capable meanwhile in a mixed environment teachers estimates need to
Be more diverse and flexible while streaming might seem to help teachers effectively Target a student’s epd it can can underestimate the importance of peer-to-peer learning a crucial aspect of constructivist theory is the role of the mko more knowledgeable other in knowledge construction while teachers are traditionally the mkos in classrooms
The value of knowledgeable student peers must not go unrecognized either I find it amazing to watch students get over an idea to their peers in ways that I would never think of they operate with different language tools and different social tools from teachers and having just learned it themselves they possess
Similar cognitive structures to their struggling classmates there is also something exciting about passing on skills and knowledge that you yourself have just mastered a certain pride and Zeal a certain freshness to the interaction between teacher and learner that is often lost by the expert For Whom the steps are obvious and the joy
Of Discovery forgotten having a variety of different abilities and a Collaborative Learning environment provides valuable resources for helping students meet their learning needs not to mention improving their communication and social skills and today more than ever we need the many to flourish not suffer at the expense of a few Bright
Stars once a year I go on a hike with my class a mixed bunch of students it is challenging the fittest students realize they need to encourage The Reluctant there are Lookouts who report back and extra items to carry for others we make it together preventing the theft of turtle
Eggs a humans have been eating sea turtle eggs and killing adult turtles for meat for Millennia however as human populations exploded and as sea turtles began to confront additional threats such as intensive fishing Beach development and climate change sea turtle populations declin precipitously today all but one of the world’s seven
Species of sea turtles are considered threaten according to the if and red list and the one that’s not the flatback turtle is listed as data deficient which means scientists simply don’t know how it’s doing be one major problem is that every year millions of sea turtle eggs
Are illegally taken by poachers for sale on the black market the situation is particularly serious in Nicaragua and Central America which is home to four sea turtle species Kim Williams Gillan who works for conservation body passo pacifical describ the poaching of sea turtle nests on the beaches of Nicaragua as uncontrolled unregulated extensive
And contested even the best protected beaches are plundered to some extent and it’s not uncommon to see poachers digging up Nest just meters from tourists watching sea turtles laying their clutch at night she said this poaching becomes particularly frenzy during the bottles Mass laying events where thousands of turtles nest on the
Same beach for a single night in a biological strategy to overwhelm natural prce see even with armed goers the numbers of poachers overwhelm military personnel by 10 to 20 to1 Williams Gillan said although many poachers are locals with limited resources during these AR boers there are influxes of
Gangs of poachers from larger cities outside local communities these are not just local poor people without other options but to protect the country’s sea turtles Williams Gillan said conservationists shouldn’t just depend on catching low-level operators if one poacher decides to stop another one will just step into his place we need to know
More about the middleman and people higher up in the distribution chain she said the Paso Pacifico solution is the creation of high-tech sea turtle eggs fake eggs convincingly crafted to look like the a real thing but which contain GPS tracking devices these have the potential to reveal the destination
Markets for traffic sea turtle eggs making convincing sea turtle eggs is not easy impasto Pacifico is still working on perfecting the prototype in particular it’s proven quite problematic to create the right texture since sea turtle eggs are not covered in a hard shell like those of birds but are quite
Flexible so pass the pacifical brought in Lauren Wilder a special effects artist in the US to create a convincing outer shell first Wilder had to get her hands on the real thing since it’s legal to send sea turtle eggs over the Border Wilder is using land turtle eggs from
California it was really opening and important for me to feel these eggs and how the shell bends a little she said to get the GPS device inside the shell Castle Pacifico is using 3D printers to make a plastic ball which will then have a GPS transmitter fitted inside this
Will take the place of the embryo inside the shell lastly the fake shells will be sealed with silicone waterproofing them you SE Turtles on average lay around 100 eggs in a nest and once the fake eggs are finished they it will be slipped in with the real ones Williams Gillan said
It might even be possible ble to deliver fake eggs into Nest while poachers are at work wary of tourists poachers will often back off if strangers come near and then return when they have gone it would be pretty easy to drop an egg in the darkar into a nest they have been
Digging up she said once the poacher picks up the fake egg alone with the real ones conservationist and law enforcement agents will be able to track them experts believe most of the stolen eggs eventually make their way out of Nicaragua possibly to El Salvador or gual however there is also growing
Concern that sea turtled eggs from Central America are actually heading to the USA from where they are sold on to other countri around the world F to date Paso Pacifico has yet to put a single fake egg in a nest but Williams Gillan said she isn’t too concerned that
Publicity for their scheme will result in poachers looking for the eggs the vast majority of the poaching is happening at night already it is hard to tell the eggs apart and at this point poachers and middlemen are not closely inspecting eggs but rather shoving them into a sack as quickly as possible of
Course poachers will eventually become aware of the prospect of fake eggs among the real ones especially when customers try to bite into an egg and break their teeth from the GPS transmitter instead so Paso Pacifico plans to do a massive deployment of as many fakes as possible
To gather a lot of data before poachers get wise knowing where the eggs go will allow conservationists and law enforcement agents to focus their resources on the right places whether it be through awareness building campaigns or crackdowns on illegal Sellers and eventually passal pacifical hopes to share the technology with interested
Parties around the world backpacking cuckoo the cuckoo is a bird which people all over Europe know from the sound it makes it doesn’t sing but makes a noise with one high note and one low note cuckoo people in Europe say that when you hear that sound for the
First time each year you know that spring has arrived in some years people hear cuckoo as early as February and in other years they don’t arrive until April but March is the typical month for the birds to arrive this is because the cuckoo lives in Africa during the winter
Months and only comes to Europe when the weather gets better people have always known that the cuckoo migrated they fly thousands of miles across the Sahara desert twice a year once in the spring and then back again at the end of the summer normally in July the young cucko
Are born in England and they leave for Africa a little later but by mid- August there are no cucko left in Europe the details of how they make their Incredible Journey have only recently been understood by scientists last May scientists caught five male birds in norick in eastern
England they put a tiny satellite tag on each Bird’s back and then set them free again the tag allowed the scientists to see where they went when they left England the scientists found that the five tagged birds all traveled about 10 Z miles that summer and all spent the
Winter in the Congo region of Central Africa incredibly the scientists discovered that the five birds all took different routes to reach their destination in Africa the first bird to which the scientists gave the name liser flew across France Spain and Morocco before crossing the Sahara Desert the
Second bird called Chris went by a completely different route he flew over Belgium Germany and Italy before crossing the Sahara desert in Libya Tunisia and Algeria were countries that the other three birds flew over on their way to Africa the scientists were also able to see that all five Birds left
Africa again 9 months later to come back to Britain incredibly they each took a different route again and not only a different route from each other but a different route from the one they had taken before for example lisst flew back to England via Algeria and France but
This time didn’t fly over Spain and Morocco Chris also crossed the Algerian desert but then continued his journey via Italy and France the two birds however both returned to the exact place in norfol where their satellite tags were fitted the year before the three other birds did not return to England
And the scientists think they died on their return Journey next year the scientists are going to put satellite tags on female Birds to see which route they take AB bubbles are a small group of seabirds native to Tropical and subtropical oceans throughout the world their diet consists mainly of fish they

Usually in the early morning or late afternoon Bea there are three varieties on the Galapagos the Blue-footed red-footed and masked boobies they are all members of the same family and are not only different in appearance but also in behaviors the Blue-footed and red-footed boobies made throughout the
Year while the masked boobies have an annual mating cycle that differs from Island to Island all catch fish in a similar manner but in different areas the blue-footed booby does its fishing close to shore while the masted booby goes slightly farther out and the red-footed booby fishes at the farthest
Distances from Shore see although it is unknown where the name booby emanates from some conjecture it may come from the Spanish word for clown Bobo meaning stupid its name was probably inspired by the bird’s clumsiness on land and apparently unwarranted bravery the blue-footed booby is extremely vulnerable to human visitors because it
Does not appear to fear them therefore these birds received such name for their clumsiness on land in which they were easy captured killed and eaten by humans D the blue footed booby’s characteristic feet play a significant part in their famous courtship ceremony the booby dance the male walks around the female
Raising his bright blue feet straight up in the air while bringing his shoulders towards the ground and crossing the bottom tips of his wings high above the ground plus he’ll raise his bill up towards the sky to try to win his M over the female may also partake in these

Sunbaked Islands form the boobies breeding grounds when ready the female blue-footed booby lays one to three eggs e after mating two or three eggs are laid in a shallow depression on flat or gently sloping ground both male and female take turns incubating the eggs unlike most birds booby doesn’t develop
Brood patches areas of bare skin on the breast to warm the eggs during incubation instead it uses its broad webbed feet which have large numbers of prominent blood vessels to transmit heat essential for incubation the eggs are thick shelled so they can withstand the full weight of an incubating bird e
After hatching the male plays a major role in bringing fish home he can bring back a constant supply of small fish for the chicks which must be fed continuously the reason is that the male has a longer tail than the female in relation to his body size which makes
Him able to execute shallower Dives and to feed closer to shore then the female takes a greater part As Time proceeds sooner or later the need to feed the young becomes greater than the need to protect them and both adults must fish to provide enough gee when times are
Good the parents May successfully fledge all three chicks but in harder times they may still lay as many eggs yet only obtain enough food to raise one the problem is usually solved by the somewhat callous sounding system of opportunistic sibling murder the firstborn chick is larger and stronger
Than its nestmates as a result of hatching a few days earlier and also because the parents feed the larger chick if food is scarce the firstborn will get more food than its nestmates and will outcompete them causing them to starve the above system optimizes the reproductive capacity of the bluefoot in

And were well circulated throughout the 19th century their use continued up until 1910 around which time the federal government became responsible for issuing monitoring and controlling all currencies that were used throughout the country once the Australian Notes act was was passed in 1910 it took 3 years
For the federal government to issue the first series of Australian notes the government followed the British imperial system where 12 P made a shilling and 20 Shillings made a pound the same act also stopped different states and their Banks from issuing and circulating their own notes the status of State notes as legal
Tender ceased from that time resulting in the Commonwealth treasury having full responsibility and control over issuing notes in 1920 however control was transferred to a board of directors directly appointed by the Commonwealth government by the end of 1924 a number of changes took place regarding the control of note issuing the most
Significant being the replacement of the Commonwealth government board of directors by the Commonwealth Bank board of directors gradually the Commonwealth Bank became the sole authority to issue Australian notes this Authority was formalized in 1945 by the Commonwealth Bank act in 1960 control was passed to another Authority The Reserve Bank of
Australia RBA which took over the responsibility of Central Banking and the issuing of notes in 1966 the RBA converted its currency from the imperial system to decimal currency and named its standard currency the dollar in the 1970s Australia experienced rapid growth in its economy and population this growth meant that more currency would
Need to be printed so the RBA began the construction of a new note printing complex in Melbourne in 1981 the first batch of notes was printed in the new complex by the printing branch of the RBA which in 1990 was officially named note printing Australia in addition to
Larger scale note printing the RBA also concentrated on developing technologically advanced and complex note printing mechanisms to guard against counterfeiting as a result of joint efforts by the RBA and the Commonwealth scientific and Industrial research organization syyro revolutionary polymer notes were invented featuring exclusively a pictorial theme of settlement incorporating elements of Aboriginal
Culture commemorative $10 polymer notes were introduced in 1988 as part of Australia’s B Centennial celebrations. inactions electronically without physically exchanging notes or coins the basic idea of developing polymer notes originated from an experiment where the RBA attempted to insert an optically variable device in the notes so that
Counterfeits could not copy them over the years a process has evolved in the production of polymer note printing which involves several steps initially blank sheets are made out of a special kind of surface material called bi a oriented polypropylene Bop a non-fibrous and nonporous mer used as an alternative
To paper and note printing that has a distinctive feel when patched usually a technique called opacifying is then used to apply ink to each side of the sheet through a die cut that has a sealed space in it for the ovd no ink is placed in this area it remains transparent the
Sheet is then ready for intalio printing a kind of printing which sets the ink in an embossed form raising the printed elements text image lines and other complicated shapes the process then prints a see-through registration device by matching the images on both sides dot by dot if the images on both sides do
Not align perfectly then the see-through device will not show any printing on it once the note is held up to a light source as a special security feature shadow image creation technique is then used by applying optically variable ink OVI which allows the print on the
Reverse side to be also seen all the notes then undergo a safety and functionality test where they are placed in front of a light source to check manually whether or not the reverse side can be seen if the nodes pass the test it is assumed that the process has been
Successful the process then moves to micro printing which is the printing of text so small that it can only be read with a magnifying glass the second last phase of the process is fluorescence printing where some texts are printed in such a way that is only visible when
Viewed under ultraviolet UV light the authenticity of a polymer note can be quickly established by holding it up to a UV light source if some texts glow under the UV light then the note is authentic the last phase of the process is called varnishing which is the overcoating of notes with a chemical
That consists of drying oil resin and thinner this Final Phase makes the surfaces of the notes glossy and more durable despite significant developments of technology and control some people argue that the life of polymer nodes as currency in Australia will come to an end due to the widespread usage of
Electronic fund transfer cards one whether this will come to pass remains to be seen one thing however seems certain innovation of currency notes in Australia will continue into the foreseeable future one computer-based systems used to perform Financial trans actions electronically without physically exchanging notes or coins the history of Cinema the history
Of the cinema in its first 30 years is one of major and to this day unparalleled expansion and growth beginning at something unusual in a handful of big cities New York London Paris and Berlin the new medium quickly found its way across the world attracting larger and larger audiences
Wherever it was shown and replacing other forms of of entertainment as it did so as audiences grew so did the places where films were shown finishing up with the great picture palaces of the 1920s which rivaled and occasionally superseded theaters and Opera Houses in terms of opulence and Splendor meanwhile films themselves
Developed from being short attractions only a couple of minutes long to the full length feature that has dominated the world screens up to the present day although French German American and British Pioneers have all been credited with the invention of Cinema the British and the Germans played a relatively
Small role in its worldwide exploitation it was above all the French followed closely by the Americans who were the most passionate exporters of the new invention helping to start Cinema in China Japan Latin America and Russia in terms of artistic development it was again the French and the Americans who
Took the lead though in the years before the first world war Italy Denmark and Russia also played a part in the end it was the United States that was to become and remain the largest single market for films by protecting their own market and pursuing a vigorous export policy the
Americans achieved a dominant position in the World Market by the start of the first world war the center of filmm had moved westwards to Hollywood and it was films from these new Hollywood Studios that flooded onto the world’s film markets in the years after the first
World war and have done so ever since faced with total Hollywood domination few film Industries proved competitive the Italian industry which had pioneered the feature film with spectacular films like eov viisi 1,913 and cabiria 1,914 almost collapsed in Scandinavia the Swedish Cinema had a brief period of Glory
Notably with powerful epic films and comedies even the French Cinema found itself in a difficult position in Europe only Germany proved industrially capable while in the new Soviet Union and in Japan the development of the cinema took place in conditions of commercial isolation Hollywood took the lead artistically as well as industrially
Hollywood films appealed because they had better constructed narratives their special effects were more impressive and the star system added a new dimension to the screen acting if Hollywood did not have enough of its own resources it had a great deal of money to buy up artists and Technical Innovations from Europe to
Ensure its continued dominance over present or future competition from early Cinema it was only American slapstick comedy that successfully developed in both short and feature format however during this excellent film era animation comedy serials and dramatic features continued to thrive along with factual films or documentaries which acquired an
Increasing distinctiveness as the period progressed it was also at this time that the avantgard film first achieved commercial success this time thanks almost exclusively to the French and the occasional German film of the countries which developed and maintained distinctive National Cinemas in the silent period the most important were
France Germany and the Soviet Union of these the French displayed the most continuity in spite of the war and post-war economic uncertainties the German Cinema relatively insignificant in the pre-war years exploded onto the world scene after 1,99 yet even they were both overshadowed by the Soviets after the
1,917 Revolution they turned their back on the past leaving the style of the pre-war Russian Cinema to the immigrates who fled westwards to escape the revolution the other countries whose Cinemas changed dramatically are Britain which had an interesting but undistinguished history in the silent period Italy which had a brief moment of
International Fame just before the war the Scandinavian countries particularly Denmark which played a role in the development of Silent Cinema quite out of proportion to their small population and Japan where a cinema developed based primarily on traditional theatrical and to a lesser extent other art forms and only gradually adapted to Western
Influence the Penny Black it might not have looked very impressive but the Penny Black now 170 years old was the first stamp to be created and it launched the modem postal system in Britain before 1,840 and the arrival of the Penny Black you had to be rich and patient to use
The Royal Mail delivery was charged according to to the miles traveled and the number of sheets of paper used a two-page letter sent from Edinburgh to London for example would have cost 2 Shillings or more than £7 in today’s money and when the top hated letter
Carrier came to deliver it it was the recipient who had to pay for the postage letter writers employed various ruses to reduce the cost doing everything possible to cram more words onto a page nobody bothered with heavy envelopes instead letters would be folded and sealed with wax you then had to find a
Post office there were no pillar boxes and hope your addressy didn’t live in one of the several rural areas which were not served by the system if you were lucky your letter would arrive it could take days without being read or censored the state of mail had been causing concern throughout the
1830s but it was Roland Hill an inventor teacher and social reformer from kidderminster who proposed a workable plan for change worried that a dysfunctional costly service would stifle communication just as Britain was in the swing of its Second Industrial Revolution he believed reform would ease the distribution of ideas and stimulate
Trade and business delivering the same promise as the new Railways Hill’s proposal for the penny post which meant any letter weighing less than half an ounce 14 Gams could be sent anywhere in Britain for about thir tip in today’s money was so radical that the Postmaster General Lord Lichfield
Said of all the Wild and Visionary schemes which I ever heard of it is the most extravagant Lord litfield spoke for an establishment not convinced of the need for poor people to post anything but merchants and reformers backed Hill soon the government told him to make his scheme work and that meant
Inventing a new type of currency Hill quickly settled on a bit of paper covered at the back with a glutenous wash which the user might by applying a little moisture attached to the back of a letter stamps would be printed in sheets of 240 that could be cut using
Scissors or a knife perforations would not arrive until 1,854 the idea stuck and in August 1,839 the treasury launched a design competition open to all artists men of Science and the public in general the new stamp would need to be resistant to forgery and so it was a submission by
One Mr Chevon that Hill used as the basis for one of the most striking designs in history Chevon who worked as a sculptor and an engineer determined that a portrait of Queen Victoria engraved for a commemorative coin when she was a 15 year-old princess was detailed enough to make copying difficult and recognizable
Enough to make fakes easy to spot the words Postage and one penny were added alongside flourishes and ornamental Stars nobody thought to add the word Britain as it was assumed the stamps would solely be put to domestic use with the introduction of the new Postal System the Penny Black was an instant
Hit and printer struggled to meet Demand by the end of 1,840 more than6 million letters had been sent more than double the previous year it created more work for the Post Office whose reform continued with the introduction of red letter boxes new branches and more frequent deliveries
Even to the remotest address but its lasting impact on society was more remarkable Hill and his supporters rightly predicted that cheaper post would improve the diffusion of knowledge suddenly someone in Scotland could be reached by someone in London within a day or two and as literacy improved
Proved sections of society that had been disenfranchised found a voice Tristram hunt an historian values the flourishing of Correspondence that followed the arrival of stamps while I was writing my biography of Friedrich angles I could read the letters he and Mark sent between Manchester in London he says
They wrote to each other three times a day pinging ideas back and forth so that you can almost follow a realtime corespondence the penny post also changed the nature of the letter weight-saving tricks such as cross writing began to die out while the arrival of envelopes built confidence
Among correspondents that mail would not be stolen or read and so people wrote more private things politically or commercially sensitive information or love letters in the early days of the penny post there was still concern about theft hunt says angles would still send Mark’s money by ripping up 5 pound notes
And sending the pieces in different letters but the probity of the postal system became a great thing and it came to be expected that your mail would not be tampered with for all its Brilliance the Penny Black was technically a failure at first host offices used red
Ink to cancel stamps so that they could not be used again but the ink could be removed when in 1,842 it was determined that black ink would be more robust the color of the Penny Black became a sort of browny red but Hills brainchild had made its mark
