Brain drain should be stopped free essay sample

Mind Drain is an oft-heard articulation utilized in India. This alludes to the fare, or leaving India of the Indian minds to various remote nations. We term it as a channel of the cerebrums since, it is accepted that, with the going out these best minds us, as a nation is at a misfortune as. With our best cerebrums working for different nations we are left uniquely with average and the lesser minds to work and create with. At the start, let us break down why there is such a large amount of this departure of mind from India and, without making a big deal about a hubbub about the cerebrums attempt to check the channel. It is be that as it may, a matter of pride for us all Indians to understand that the world has, starting today perceived the Indian mind among the best cerebrums of the world. This is the reason remote nations energize bringing in the Indian mind. We will compose a custom article test on Cerebrum channel ought to be halted or then again any comparative theme explicitly for you Don't WasteYour Time Recruit WRITER Just 13.90/page Then again, our minds are likewise glad to go out in light of the fact that they get an amiable working climate out there. There, in remote grounds there is energy about acceptable work, and the earth of work is neighborly not normal for the overall conditions in India. Other than this, the attractive compensation bundles there are no match to the thin partner of a compensation return here in India. With this circumstance wherein both the Indian minds and the remote nations discover the business worthwhile and exceptionally fulfilling how and for what reason should it be halted. With respect to why of the inquiry I feel that, it ought to be shortened if not halted on the grounds that, if the best go out, what are the possibilities of improvement in our own nation? For his again we, ourselves are to be faulted. In the event that we make the environment more beneficial for good work, I feel probably some the minds may remain back in India. With all their mastery being out, we need to acknowledge that India is at a misfortune at the same time, we can't generally accuse the individuals going out as, who does need to improve standard of life? The reality of their going out does by all accounts give off an impression of being out of line to India when we have the skill, the mastery, for what reason should we not receive the reward, all things considered, Be that as it may, so as to exploit the minds, we need to plan something for draw them to remain inside for which I daresay, India needs to do a great deal of work. With respect to issue of how this mind channel can be halted, the arrangement isn't straightforward however yet it isn't incomprehensible. The Government must see that the workplace gave, and gratefulness be given to acceptable work. With respect to the compensation bundles, they can likewise be improved so as to draw in at any rate a couple of the minds who might be not so much aspiring but rather more devoted. For, I accept that, few cerebrums may want to remain back in India if the imperative changes are made for them in the whole arrangement of working example. In this manner, to forestall a cerebrum channel from India it isn't adequate to simply yell about it and make an issue of it. We should progress in the direction of the objective of giving them in any event the close to comforts to them of what they would get in any of the outside grounds they may decided to go to. In the event that we attempt this, we may prevail with regards to keeping down at any rate a couple of them, for helping us to create India. The cerebrum channel might be making concern us as, the best of our Indian minds leave the nation, nonetheless, there isn't just a dark haze of passing up our best, there is additionally a silver covering to the channel. The cerebrums that leave India are at this point such a generous number, that they structure a tremendous network in themselves, called the Non-Resident Indians. These NRIs are a steady wellspring of pay for India as far as outside trade. With their settlements home, they contribute significantly to working up the countrys remote trade. Along these lines, this mind channel is and will proceed with except if we put a plug by furnishing them with all the more working offices at home and give them more than the other customary cerebrums as far as monetary advantages. For whatever length of time that we cannot do this for them or dont do this for them the cerebrum channel can't be halted and the best of Indians will keep on discovering homes abroad. While they keep on going out we, the Indians should keep being content with the way that they have in any event become a power to deal with, and they get a great deal of name and distinction.

Journalists can talk the economy up or down - Emphasis

Writers can talk the economy up or down Writers can talk the economy up or down The media should practice alert when announcing the Euro emergency, specialists caution, as the language that columnists use is by all accounts influencing our financial fortunes. As indicated by another report from the Emphasis Research Center, there is a solid connection between purchaser certainty and the utilization of the word recuperation in the press. The investigation followed the presss utilization of the word recuperation (alongside green shoots) during the ongoing downturn and the months paving the way to it. In doing as such, specialists found that the utilization of the terms expanded altogether even as the monetary markets were still in freefall. From August to November, for instance, the FTSE 100 fell a huge 24 percent. However references to recuperation rose by 26 percent in a similar period. In the interim, only months after downturn got official in January 2009, customer certainty started to rise and kept on rising the more recuperation showed up in the media. Significantly, nonetheless, customer certainty falled marginally behind the presss utilization of the word. The specialists recommend that the language utilized by the press may have helped float buyer certainty and thusly added to the UKs possible move out of downturn. They likewise caution that the media itself could trigger the much-dreaded twofold plunge downturn. Loot Ashton, Chief Executive of Emphasis, says this seems to help recounted claims that the press can talk the economy up or down, regardless of whether they do so accidentally. It may be the case that simply rehashing the word recuperation, similar to a mantra, some way or another saturated the subliminal of both people in general and the market, he clarifies. This might be a case of columnists affecting the news, just as announcing it. The examination venture started as a positive option in contrast to The Economists R-word list, which tracks how regularly the word downturn shows up in The New York Times and Washington Post. In the course of recent decades, the record has spotted major monetary defining moments, for example, the beginning of downturns in America in 1981, 1990 and 2001.

Recuperation Watch followed the quantity of articles containing the words recuperation and green shoots in the UK broadsheets between January 2008 and May 2010 against the setting of market movement and mediation measures. These measures incorporate the UK Governments upgrade bundle, reported in November 2008; the beginning of quantitative facilitating in March 2009; and the G20 highest point pioneers $1.1 trillion bundle to handle the money related emergency in April 2009. While these different components may have added to reestablished confidence later on for the business sectors, likenesses between the ascent in paper references to recuperation and the Nationwide Consumer Confidence Index seem critical. 2. Recuperation Watch is the subsequent research venture distributed by the new Emphasis Research Center. Propelled in April 2010, the middle behaviors investigation into language, correspondence and composing aptitudes in the UK. 3.

Design 101 Asymmetrical and Symmetrical Balance

Design 101 Asymmetrical and Symmetrical Balance When it comes to creating art, or designing a practical piece such as a calling card or a cover letter template, balance is rather important both for aesthetic and professional reasons. We are naturally attracted to well-balanced pieces of art, architecture and naturally occurring sights and events, and throughout our history, we’ve been trying to emulate the principles of balance.Yet despite the need for symmetry, we often purposefully destroy the visual equilibrium, shake up the conventional norm and create something different, either for the sake of variety or to take a stand and deliver a message in a stronger, more dynamic way.I this text we will learn about the nature of balance, see its effect in our surroundings and artworks, and discuss the differences between the two types of balance: symmetrical and asymmetrical.BALANCE IN NATURE AND ARTWhen it comes to art, we may say that balance represents the purposeful organization of visual elements of varying weight. When we say w eight, we are referring to the overall shape, form, and significance of a particular visual element. Combining these elements into a cohesive unit, whether that unit is a painting, a sculpture, or a wedding invitation is how we create artworks.Balance can be found everywhere in the physical world, in greater or lesser degrees, and great masters have been implementing it in their work since forever. In nature, we will usually recognize the objects which are able to carry their own weight as balanced. Imbalanced objects are easy to topple.To illustrate balance in the simplest of terms, we may use the see-saw as an example. If we place two people of more or less equal weight and size, the beam would be in the state of balance, with weight equally distributed on its two sides, and equally distanced from the center of the balance or the fulcrum. This center of balance is also the center of the composition of an artwork or a design.However, if we place two persons of different weights on the see-saw, one smaller and one larger, the beam of the see-saw would be off balance. The only way to balance the beam would be to either move the larger person towards the fulcrum until the balance is reached or to place another smaller person on the other side of the see-saw.This is applicable in terms of design as well. When we say that a visual item has greater or lesser weight, we are referring to its ability to draw out attention. If our attention is held mostly on one particular visual object then we say that that object has a greater visual weight.Thus, in an art piece such as a painting, visual weight is what replaces the physical weight of the object depicted, while the visual direction is what replaces the direction we position objects in real life in order to achieve balance, much like in the case of the see-saw.Visual weight is of crucial importance when it comes to the emphasizing the elements of your design. Usually, the greater the visual weight, the greater the imp ortance of the object portrayed. If all the parts of your design are of equal weight, you will present a balanced, engaging, aesthetically pleasing composition.This is not applied to objects alone, but on living creatures as well.Observe the wings of a butterfly â€" they are vividly colored and fragile, and both wings are colored in the very same way, the patterns and shapes matching perfectly. This is an example of balance in nature.Trees, however, follow their own path. The branches are seemingly growing haphazardly, and rarely will one see a tree perfectly balanced in terms of shape. But there are cases of a more balanced “design”, of course.In normal circumstances, balance is a desirable feature to have in one’s artwork, but sometimes, a stronger message can be sent by disregarding the principles of balance and making one’s art asymmetrical and imbalanced. Thus, the choice is truly between a classical, stable, formal expression vs. a more modern, dynamic expression, as e xemplified in the two types of balance we will explore within this text.SYMMETRICAL BALANCESymmetrical balance is a type of visual balance where a work of art is composed in such a way that all visual objects are equally distanced from the central axis, or the central point, of the design. And not only that â€" the objects from both sides of the axis look the same, only as reflected in a mirror.Remember the butterfly â€" the design of its wings is an example of the symmetrical balance found in nature, where all the opposing shapes are counterparts of one another and are in perfect proportion. And such near-perfect symmetry has always been considered as aesthetically pleasing, even today.However, such perfect symmetry is actually very rare. The most common type of symmetrical balance is the so-called near symmetry we see in a human face. The left and the right side match seemingly perfectly, but there may be slight variations, more or less noticeable.In the case of design and art in general, symmetrical balance is fairly easy to accomplish and is much more prominent than in nature.Observe, for instance, the marvelous Taj Mahal, one of the most cited examples of perfect symmetrical balance in architecture. All the details match one another on both sides of this majestic construction. There is not a single object taking the spotlight, or ruining the overall impression of purest harmony a perfectly balanced display of craftsmanship and artistic taste.The symmetry of the visual objects tells us that we should focus on the building as a whole, not on any particular visual object. Thus arranged, the symmetrical design gives off the feeling of serenity and classical elegance. Another notable example of symmetrical balance is Da Vinci’s Proportion of a Human. This work as well, once cut in half along the central axis, would have the objects of the two sides match each other perfectly as if reflected by a mirror. Da Vinci’s work also serves the perfect proportions of the human body, which was such a prominent motif in classical art.Thus, symmetrical balance is usually found in the traditional forms of art, its other name is “the formal balance”. It gives us the feeling of stability of form and structure, but also of peace and harmony. However, symmetrical balance is often considered to be a bit dull and boring by some critics. If you wish to create an event invitation, an aforementioned calling card or a logo, designing a symmetrically balanced item would be a preferred option. However, if you’re working on more creative objects, consider using some more dynamic options.TYPES OF SYMMETRYHere are the basic types of balance for you to use in order to create your design:1. Reflection symmetry Reflection symmetry (otherwise known as bilateral symmetry) is the type of symmetry we were refereeing to earlier in the text while explaining Taj Mahal and the Proportion of the Man. This type of symmetry is what comes to mind most often when one mentions the word symmetry.The central axis (or the central point, or the fulcrum of the composition) can be positioned in any way, vertically or horizontally, and it does not influence the symmetry in any way. Symmetry over multiple axes is also observed in nature. The best example for that would be the perfect shape of a snowflake.In the most perfect form of this sort of sy mmetry, there are no variations whatsoever between the two halves of the composition. Thus, this form is called “pure symmetry”. Pure symmetry is very rare in nature, for in the majority of cases variations can be found. If we remember the aforementioned example of the human face, we will see that both sides are the same, but if we look carefully, we may see that, for example, the left corner of one’s lips is curved upwards just slightly more than the right one.Our bodies are symmetrical as well, and yet, some people are left-handed, while most have their right side more developed, thus making it the dominant one.This sort of reflection symmetry is called the near symmetry.2.  Rotational Symmetry Rotational (radial) symmetry can be observed when visual objects of a composition perfectly rotate around the center of the composition. As long as they share the same center, distance, frequency, and angle of visual objects, rotational symmetry exists. In nature, this type of symmetry can be seen in the shape of the petals of many types of flowers, most notably daisies and sunflowers. When it comes to art, some of the best examples of how artists use rotational symmetry is making clay pots and vases â€" an art form thousands of years old. Some of the most beautiful stained glass windows of cathedrals are rotationally symmetrical. 3. Translational SymmetryThis type of symmetry occurs when we repeatedly use the same type of visual elements in different parts of the composition. Repetition is what carries the symmetry, and the best example of this type of symmetry is â€" the fence post. This form of symmetry is perfect for creating sound, speed, and action in your design.Translational symmetry can be applied in all directions as long as the basic orientation of the visual objects remains unchanged.4. Glide Reflectional Symmetry Glide reflectional symmetry can often be observed. If we walk over a sandy beach, a soft patch of ground or a snowy area, we leave our footprints behind us. And as we already know, footprints are usually symmetrical to one another, yet, the footprints may slightly differ.You can apply this type of symmetry when designing your composition in the following way. Make a copy of a visual object, but move the copy so it is not positioned against the original. Instead, move it in another directi on, or invert it, or make it seem like it is fading away, and thus create the illusion of movement.ASYMMETRICAL BALANCEAsymmetrical balance happens when you organize the composition in a seemingly chaotic way (visual objects of varying weights are not mirror images of one another), and yet, a sense of balance is somehow still present.This may be accomplished in various ways. For example, you may place a visual object of great weight on one side of your composition, then balance it with a number of smaller ones on the other. This will make your composition more dynamic and modern and might help you deliver your message with greater effect.Remember: darker and larger objects have more weight than smaller and lighter objects, so take these criteria into consideration while creating your design.Asymmetrical images attract more attention due to the more complex relationship between objects used to create the composition. Thus, this type of balance tends to be more interesting the harmon ious expression of symmetrically balanced compositions tend to be somewhat passive, while designers using asymmetrically balanced designs usually do not need to worry about maintaining the attention of the audience.When looking for examples of asymmetrically designed compositions, Vincent Van Gogh’s “Starry Night” is one of the most impressive variants of this design. The bright moon on the top right corner is balanced by the dark cypress trees on the bottom left side of the painting.The stars and the clouds on the upper half of the painting are balanced by the detailed portrayal of the town on the bottom half of the painting. Just like the moon and the cypress trees balance each other through the contrasting relationship of light and dark, the same can be said for this as well.Symmetrical designs, when compared to the asymmetrical ones, are often perceived as dull and predictable. With asymmetrical designs, you can play with shapes in unpredictable ways, create patterns with greater flexibility, and still, these seemingly haphazard organizations can make a lot of sense and tell your story with great strength and impact.Bear in mind, however, that, although you gain a greater freedom of expression, creating asymmetrically balanced designs may prove more challenging than creating a symmetrically balanced design.A poorly balanced composition induces a feeling of tension as if a painting could tip on one side and fall. You do not wish to over-saturate your design with randomly positioned visual items!TYPES OF ASYMMETRICAL DESIGNThere are several ways you can use asymmetrical design in your compositions. Some of those include the following techniques:Arrangement by color â€" human eyes are naturally drawn by color. Artists use this trait of ours when creating asymmetrical designs to balance larger areas of more neutral colors with small areas of vivid, bright colors.Arrangement by shape and value â€" as we have mentioned above, visual objects of light colors and small size have less weight than larger, darker visual objects. Several smaller, lighter objects can be used to counterbalance one larger, darker object. Large, empty areas of a composition can, thus, be balanced by smaller, intricately detailed areas.Arrangement by texture â€" an area rich with color fluctuations and different textures can be balanced by a smooth area of the composition without any remarkable texture variations.Arrangement by eye direction â€" A spectator’s eye can be easily directed into one direction or another, depending on the way you organize your design.Triangular shapes can naturally be used as pointers, and people on a painting or a photograph looking at a certain point will naturally draw your attention towards that point.Also if they are pointing in some direction we will feel inclined to look that way ourselves and see just what they are pointing at.It makes us curious, and it’s an efficient way to draw the spectator’s attention to the key ele ment of your design.CONCLUSIONAs we can see, asymmetrically and symmetrically balanced designs can be used in very distinct ways.If you’re in need of a more formal, harmonious, aesthetically-pleasing structure, using symmetrically-balanced design would be a good course of action. However, do not forget that sometimes the calm and serenity of this type of design may not be as remarkable as you may need it to be.As beautiful as it may be, it may at times come up as too passive and formulaic.If you’re trying to create an impactful, dynamic composition, asymmetrically balanced design is the right choice, as long as you mind your way of organizing and creating your composition. Scattering visual objects randomly may do the exact opposite of what you require, so tread carefully.Please, consider carefully both of these approaches to creating your design, measure their pros and cons, and choose wisely!Hopefully, this article gave you some insight into two frequently used instances in th e world of artists- asymmetry and symmetry.

Utopia and Il Muqaddimah Essay - 599 Words

Utopia and Il Muqaddimah both show the importance of families and social groups in the civilization they live in. Utopian families all have an equal role in the cities they live in; they are a microcosm of their city and its objective to survive; however, in Il Muqaddimah the subjects have the responsibility to help the ruler prosper. Utopians work and in return share what they earn, while subjects work for their survival. Utopians all have an equal work load and subjects hardships depend on their social status both situations lead to prosperity. Utopians work for the commonwealth and in result no one worries about hunger or payment, â€Å"products of each household are taken to designated houses there and each kind of goods is separately†¦show more content†¦Utopians have balance and this causes harmony, while subjects and rulers must know and not step out of their roles because it would lead to downfall. Utopians all have an equal work load this is very common in families ; the husband works and brings in money while the wife stays home and keeps the house and children in order, the children provide a job for the wife and in time will help their mother. This is all equal work because the without the husband there would be no food, without the wife the house would become chaotic, and without children the wife would have nothing to keep her busy which results in laziness and no prosper, â€Å"if all those who work away at pointless tasks and, together with them, that whole crowd of lazy, languid idlers, if they all were put to work-and useful work at that- you can easily see how little time would be enough to produce all thee goods required for human needs† (More 1711). This highlights the importance of work, without everyone pulling their own weight others suffer and must work twice as hard instead of harmonically. Rulers have an important job that promises prosperity to their territory. This job requires them to provide hope to subjects, becau se without hope people began to fall apart and no longer desire the will to succeed

Some cultures have contributed to colorist beliefs that light hair and blue eyes are the standard for beauty. People who fall victim to this altered view have gone as far as skin bleaching and extreme poisonous routes which have contributed to the deaths of women trying to stay in trend. Countries such as India victimize females with favor placed on lighter skin. Africa is a predominantly dark skinned continent that has taken up the fair skin death trap; a country that should be praising rich cocoa skin, or darker skin that is native to India begun praising European like skin.

Cpu Research Paper Free Essays

CPU: Past, Present,   â€Å"A CPU (central processing unit) is the â€Å"brain† of the computer; it follows the instructions of the software to manipulate data into information. † (Sawyer, 2010, p. 208) The CPU performs logic and arithmetic operations, controls instruction processing, and supervises the overall operation of the computer. We will write a custom essay sample on Cpu Research Paper or any similar topic only for you Order Now The main components of the CPU are the CU (control unit) and the ALU (arithmetic/logic unit). (Dugger Gerrish, 1994, p. 78) The CPU also has registers which temporary store data during processing, and buses that act as roadways which transmit bits of data within the CPU and to other components on the motherboard. CPU: The control unit deciphers the instructions from the input and moves them into memory. For each instruction the CPU will fetch the instruction, decode the instruction, execute the instruction, and store the result. These four basic operations are known as a machine cycle. The control unit is therefore responsible in the CPU to instruct and control where the data goes to and what will happen to it. (Sawyer, 2010, p. 208) ALU: The arithmetic/logic unit executes data that the control unit has sent to it. It performs basic arithmetic operations such as addition, subtraction, multiplication, and division. The ALU also performs basic logic operations such as comparing two numbers to see if they are equal, less than, greater than, or not equal. (Dugger Gerrish, 1994, p. 581) Registers: â€Å"Registers are high-speed storage areas that temporarily store data during processing. † (Sawyer, 2010, p. 209) The CPU contains several types of registers such as an instruction register, address register, storage register, and an accumulator register. These registers may store a program instruction, store data while being processed, or store the results of a calculation. Without the registers the control unit or arithmetic/logic unit could not complete their work. Buses: â€Å"A bus is a group of parallel conductors which carry information. † (â€Å"Microprocessors,† 1983, pp. 2-2) The conductors may be wires in a cable, foil patterns on a printed circuit board, or microscopic metal deposits in a silicon chip. Buses act as data roadways to get data from one place to another as needed. The term CPU/central processing unit has been in use since the 1960s. Nowadays, we are more familiar with the term microprocessors which are CPUs that are manufactured on integrated circuits in a single-chip package. However, before getting into today’s technology I will take a look at the past CPU technology. Past Exactly which computer was the first electronic computer completed in the United States is a controversial subject. Iowa State University claims that the Atanasoff-Berry Computer at ISU was completed in 1942 just before its creator was called up for duty in the war effort. (Munns) Another computer at the University of Pennsylvania which was funded by the military was completed in 1946 by J. Presper Eckert and John Mauchly. First Generation: Eckert and Mauchly’s invention was called the Electronic Numerical Integrator and Calculator, or as many now know it, as ENIAC. This first generation computer weighed 30 tons and contained 18,000 vacuum tubes. ENIAC could do 5000 additions per second. Each specific sequence of calculations had to be hard-wired into the machine. To change programs, ENIAC had to be completely rewired. ENIAC is generally known as the first electronic computer in the United States. However, since ENIAC could not store a program it did not have, what we would call, a CPU. Dugger Gerrish, 1994, p. 571) In 1945 John von Neumann created a design for a computer system. His design included four basic units for a computer: a CPU, an input device, an output device, and storage. (Dugger Gerrish, 1994, p. 571) In 1946 John von Neumann joined with Eckert and Mauchly at the University of Pennsylvania to create the Electronic Discrete Variable Automatic Comp uter (EDVAC). EDVAC was completed in 1949. It contained almost 6000 vacuum tubes and had 12,000 diodes. EDVAC covered 490 square feet of flooring and weighed almost 9 tons. It required thirty people to operate it. EDVAC is considered the first truly programmable electronic computer that included a central processing unit. No doubt the CPU was enormous, but still a recognizable CPU. (â€Å"EDVAC†) Second Generation: In 1954 Texas Instruments introduced the silicon transistor. This revolutionized computer technology and created the Second Generation of computers. Transistorized CPUs of the 1950’s and 60’s were no longer hampered by vacuum tubes and electrical relay. Second Generation computers were smaller, faster, more rugged, and more reliable. â€Å"With this improvement, more complex and reliable CPUs were built onto one or several rinted circuit boards containing discrete transistor components. † (â€Å"Central Processing Unit†) Third Generation: The development of integrated circuits and their use in computers began in the mid 1960’s. This shift in technology brought about the Third Generation of computers which were faster, more reliable, cheaper to operate and much smaller. Throughout the advances in computer technology and electronics the CPU continued to become faster and smaller. Fourth Generation: In the early 1970’s, Ted Hoff at Intel invented the first microprocessor. Essentially, this was the first time that a complete processing unit was contained within a single chip and it revolutionized the way computers were applied and designed forever. This is where the Fourth Generation of computers was born. The Intel 4004 was a four bit device, measured 1/8 inch by 1/6 inch, and could execute 60,000 operations per second. (Dugger Gerrish, 1994, p. 574) By 1972 Intel had come out with an 8-bit microprocessor, the Intel 8008, and within a year had bettered it with the Intel 8080 which could execute about 290,000 operations per second. In 1979, Motorola developed a 16-bit microprocessor. The Motorola 68000 was very popular in the blossoming personal computer market. Around the same time Intel rolled out their 16-bit microprocessor; the Intel 8086. While other companies tried to compete in the microprocessor market, it was generally Intel and Motorola who were in the race to built smaller and better processors with each other. By the mid 80’s each had produced 32-bit microprocessors. Beyond: According to Moore’s Law, at our rate of technological development, the complexity of an integrated circuit will double in about 24 months. By the early 90’s, 64-bit microprocessors entered the market. Each succeeding processor is smaller and can produce data much faster. The 90’ saw Intel introduce its first Pentium chip and Motorola introduced their Power PC CPU. Throughout the 90’s Intel improved on its Pentium technology releashing the Pentium Pro, Pentium II, Pentium MMX, and Pentium III. In the late 90’s AMD introduced their Athlon CPU. The Athlon worked at 800 MHz. In 2000, both Intel and AMD released 1 GHz microprocessors in the Pentium 4 and Athlon CPU. By 2002, Intel’s Pentium 4 reaches 3. 06 GHz. By 2006, both Intel and AMD introduce dual-core processors. 64-bit processors have been around for use in mainframes and supercomputers, but now 64-bit processors are being made for personal computers. Present Today’s main competitors for CPU’s in microprocessors are Intel and AMD. Motorola sold off their semiconductor manufacturing section to become Freescale, and has basically bowed out of the CPU race. CPU’s of today are extremely fast. The new Intel Core i7-980X Processor Extreme Edition released the beginning of 2010 has six cores, 12 threads, a max turbo speed of 3. GHz , a 12 MB Smart Cache, and a clock speed of 3. 33 GHz. (â€Å"Intel Processors,†) â€Å"The faster a CPU runs the more power it consumes and the more waste heat it produces. † (Sawyer, 2010, p. 206) For that reason, rather than increasing clock speed, Intel and AMD have pursued using multi-core technology, which employs additional CPU cores and runs them in parallel. Dual, Quad , and multi-core processors are very popular today in CPUs for computers, games and other technology that needs a CPU. Future 128-bit microprocessors are still being developed. Some experts predict that advances in microprocessor technology will produce a 50 GHz processor by 2010, the kind of power that will be required to support such function as true speech interfaces and real-time speech translation† (Sawyer, p. 206) ClusterOnaChip (CoC) is a popular example of the future in CPU technology. Engineers are working on how to place thousands of more processors in a â€Å"cluster† on a single chip. IBM in collaboration with the Georgia Institute of Technology has created a prototype silicon-germanium hetero-junction bipolar transistor able to operate at a speed of 500 GHz at 4. degrees Kelvin. At room temperature, the transistor achieves a speed of 350 GHz. â€Å"This demonstrates that speeds of half a trillion cycles per second can be achieved in a commercial, silicon-b ased technology, using large wafers and low-cost, silicon-compatible manufacturing techniques,† says John D. Cressler, Byers Professor at Georgia Tech’s School of Electrical and Computer Engineering and a researcher at the Georgia Electronic Design Center at Georgia Tech. Our current technological knowledge is not good enough to produce the microprocessors and CPU’s of the future. We are limited by our current materials and in need of innovation to jump start us towards even smaller and faster CPU’s. One can only dream of the day when rather than having a bulky transistor made of silicon, we have processors that are scaled down to the size of an electron itself. Conclusion With Moore’s Law in mind, we can see that over the past decades we have certainly obeyed his law. From ENIAC to EDVAC, to transistors, to integrated circuits and single chip microprocessors, CPU technology has evolved and is still evolving to bring us the computers that e want and need. Further advances into CPU technology will allow us to compute faster and realize scientific discoveries that can change our world for the better. Our thirst for deep space exploration could become a reality. Medical research will be simplified. The possibilities are endless. References (1983). Microcomputer Basics.

Strategic Management of BHP Billiton Limited †Free Samples

Question: Discuss about the Strategic Management BHP Billiton Limited. Answer: Introduction: BHP Billiton has been one of the leading companies in the resource industry. It was formed with the merging of BHP and Billiton to bring an exceptional amalgamation of low-cost and high-quality resource assets. It is complemented by a very strong and effective team of management that is determined for the operation of the assets in an efficient manner. The report deals with the analysis of the internal environment of BHP Billiton which provides the insights into the capabilities and resources of the company (Barney Hesterly, 2015). BHP Billiton Limited is the world's biggest miner whose net profit is generated from the revenues of $820 billion and more on an average of six months. Another fact that is new for the world to know is that Arrium which is BlueScope Steel and ex-OneSteel were both a part of BHP. However, they were removed from the amalgamation in the year 2002 and 2000 respectively. BHP was almost taken over by an entrepreneur named Robert Holmes A Court in the year 1985 (Bettis, et al., 2015). It was saved from being taken over when a deal was made with the Elders IXL. Peter who was Robert's son is a co-owner of the team of NRL south Sydney Rabbitohs, along with Russell Crowe. Resources, Capabilities and Core Competencies As per Chen, Delmas Lieberman, Key performance indicators (KPI) have an important role in the measuring of the effectiveness of the business in relation to the identification, requirement and the strategic objectives. Determination of the success of the business and the activities of the business is not going to be clear and quantification of attainment of the goal is not possible without Key Performance Indicators (Chen, Delmas Lieberman, 2015). The first key performance indicators that matter for BHP Billiton are cost to acquire a customer, revenue per customer, and the lifetime value of a customer. The strength of BHP Billiton is that it is among the largest suppliers copper, silver, uranium, aluminium and lead. It leads the list of global producers of metallurgical coal, manganese and iron ore with Brazil, South Africa, and Australia. The company operates in Australia, South America, South Africa and the United States. The thermal coal generation by the section of the Energy Coal generates electric power for the concerns of the general industries. The weakness of BHP Billiton lies in the wide range of projects that it executes. The feasibility of all the projects has the probability of being a source of generation of revenue in a cost effective manner of execution of the projects. BHP Billiton can further operate on strengthening the brand position by the induction of the innovative solutions regarding marketing. The internal analysis of the company provides us with the insight so the policies, plans, and objectives of the company and in what manner they are obtained. The strengths, weakness, opportunities and threats associated with the company are understood through the internal environment analysis. According to Eden Ackermann, the global organizations have been transforming themselves completely in the in the age of information. BHP Billiton has the ability to exploit the assets that are intangible and this exploitation is turning out to be a better decision than the ability to regulate the tangible assets. BHP Billiton is expanding the operations of its business on the global platforms by implementing the balanced scorecard concept which is assisting it in complementing the analysis of the financial performance of the business (Eden Ackermann, 2013). The resources and the core competencies are the measuring criteria of the customers' perspectives, learning, and growth along with the internal business process. As per Freeman McVea, the resources of an organization denote to the human resource, physical resource, financial resource, and the information resources that are brought together in the orientation of the objectives of the organization for the accomplishments of the goals. The managers of any organizations are primarily responsible for the management and acquiring the resources in order to achieve the goals (Freeman McVea, 2015). The physical resources that BHP Billiton has are silver, zinc, lead mines in the Broken Hill near South Wales in Australia. The company also has an efficient and effective team of managers and employees to support it in its business without them BHP Billiton would not be able to make it far in the global market. Core competencies are the unique set of skills or technologies that are used by organizations to create a distinct customers value. The unique capabilities of the organization mainly refer to the personified in the collective knowledge of the individuals working in the organization along with organizational systems that have significant implications on the manner of the interaction of the employees (Frynas Mellahi, 2015). The core competencies of BHP Billiton change and adjust with the changes and developments of the company. The core competencies of BHP Billiton don do not remain rigid with time and the company can optimum utilization of the given resources and associated them to the new scope and opportunities provided by the environment. The resources of BHP Billiton are the inputs as the core competencies of the production process which include the capabilities associated with the skills used for the integration of the team of resources so that they can be utilized in a more efficient and effective manner (Hill, Jones Schilling, 2014). The development of a Western Australian Iron Ore biodiversity strategy and the incorporation of the continual environment studies in its operation process along with state of the art infrastructure and machinery are considered to be among the core competencies of BHP Billiton. The core competencies of BHP Billiton includes the techniques that the company has developed in the Eagle Ford and the development plan that is called for the subsea wells that are connected via pipelines and monitoring and control umbilicals to the onshore gas plants. Theses infrastructures are much stable to be operated during the cyclonic storms and any kind of climatic and weather conditions (Hitt, Ireland Hoskisson, 2015). The capabilities of an organization are referred to the ability of the company to manage the resources such as the human resource in an efficient manner in order to gain a competitive advantage over its competitors. The organizational capabilities of a company must be in orientation towards the ability of the company to meet the demands of the clients and the customers. The core competencies of BHO Billiton include the simplification of the portfolio, discipline regarding capital and productivity (Morden, 2016). VRIO Analysis: The VRIO analysis is performed in order to determine the conceptual framework of the strategic scheme of BHP Billiton. The primary objective of the conduction of such analysis is to determine the capability worth or resources of BHP Billiton. Value: As per Peteraf, Gamble Thompson Jr, the most important question that is raised if the ability of BHP Billiton is there to make most effective use of the resources available to it or does it make efforts to exploit and explore the opportunities. It also focuses on the inflicting threat that is posed to it regarding its position in the market. If the company is incapable of posing threat in the global market then it may lead to exposal of its weaknesses (Peteraf, Gamble Thompson Jr, 2014). In the context of BHP Billiton, the abundance of assets and resources is considered as the strengths in the industry of mining and other companies which are its competitors who might be considering themselves as threats in opposition to the capabilities of resources of BHP Billiton. Rarity: BHP Billiton is recognized as one of the mining companies which have the competitive advantage. This company does not have insufficiency of capabilities and resources. Thus, it has advantages from other competitors because of its huge range of resources and assets (Rothaermel, 2015). Immutability: The cases of compatibility are illustrated via the structure of the analysis which represents the internal environment of the BHO Billiton. This determines the sufficiency of costs disadvantage in aspects of the capabilities and resources in the procuring and development of resources and assets in comparison to the competitors (Simon, Fischbach Schoder, 2014). The mining companies such as the BHP Billiton have valuable and rich resources can be difficult to match for other global competitors so as to gain advantage. Organization: BHP Billiton after incorporating the concept rarity, value and immutability of the assets, capabilities, and resources has stepped into the next procedure to organize the company in an appropriate and efficient manner to make optimum use of the capabilities. Value chain analysis: The value chain analysis of BHP Billiton facilitates the physical representation of several processes for the BHP Billiton which involves mining and extraction of the raw materials and providing the conclusion the process by providing the final product known as the value chain. Primary activities: The Facilitation of the assortment of the inbound movements of metallurgical coal, minerals, manganese, iron and silver ore from the mining is site to site of manufacturing. Support activities: This procedure of procurement of the raw material like the silver extracts diamonds, metallurgical coal, manganese, and iron ore from the mining sites to the manufacturing units where the equipment and plants are situated (Stead Stead, 2013). The technical unit in collaboration with the processing unit is associated with pertaining equipment like software, technological and hardware knowledge which is presented by BHP Billiton in transforming the inputs into final products. The activities such as finance and accounting control the quality and public relations support BHP Billiton. Margin: Margin is basically the difference between the products selling price to its production price. In other way it can be said that its the ratio between companys revenues and expenses. Coming to BHP Billiton, keeping track on margin is very necessary because it will show that company is profitable or not (Stead Stead, 2013). Culture: The corporate culture denotes to the ideas and beliefs that the Company has and the manner in which these affect the process of business and the behaviour of the employees. BHP Billiton works towards the supremacy and initiatives in promoting a culture that honours and values the high moral principles, business and individual admiration and integrity for others. ICEBERG analogy As per ICEBERG analogy, Culture is divided into 2 parts named as internal unconscious part and external conscious part (Bayne, 2015). External conscious part represents those things which can be seen physically. Some of the examples are dance, art, music, dressing sense, language, behaviour towards employers. But on the other hand internal conscious part represents which cant be seen physically such as beliefs, values, motivations, social rules etc. (Bayne, 2015). Strategic issues in management: Uncertainty: It can be denoted as an issue in the daily business. It is comprehensive as the individual incapability to predict some aspects in precise. The managers need to deal with various kinds of uncertainty in the world of fluctuating market (Teece Shuen, 2016, May). The organizations face ambiguity in the environment of the organization macro-economic form, social, technological, environmental and political limitations in which the functioning of BHP Billiton is taking place. Complexity: It determines the factors which have to be considered by BHP Billiton while preparing the strategies. The major strategic issue in business is the primary alteration in the regulations than the expectations. Conclusion: Rapid globalization, growing and accelerating innovation and competition associate to the complexities, ambiguity, and volatility of the company. BHP Billiton requires more approaches to confronting the barriers of intricacy in business which should be based on the strategic planning. Internal analysis helps to find out the companys cost position, competitive nature and competency in the market place. Conducting internal analysis helps to provide useful information about the organisation. By examining the mineral and developing the business is a risky task even if the BHP Company is huge though it has support from the government. The litigation fee for the oil spill can charge them with the indefinite costs along with the clearing costs when there is a change in the demand of the customer is affecting the commodity prices because of which the income ways of BHP will become unstable. Hence, as a result, the BHP should formulate the strategies in such a way that the management will not face any risk in the future with respect to the competitive advantage and the current issues.

3 Essays - Dystopian Literature, Films, Human Sacrifice, The Lottery

Roberts 1 Carla R. Roberts Sharon Wallace English 120 7 June 2011 Setting in Shirley Jackson?s ?The Lottery? It is likely to assume that a lottery is a good thing. We all want to win something in life. Whether a car, a trip to Hawaii, or a million dollars, we all want the chance to be the lucky one of many. The townspeople in the story the lottery, seemed to be gathering for such an event with joy and enthusiasm. Everyone was waiting anxiously for the lottery to begin. At least that?s how it seemed. As the story progressed, it is revealed that they are all, in fact, afraid of the results. In actuality, no one really wanted to hold the winning ticket. Cleverly, the author opens the story by painting a joyful mood. It was sunny and warm. The flowers were in bloom. Children were laughing and playing. Women gossiped amongst one another while men spoke of family and the fields. The characters seemed at peace. They were calm and content. Even the stories focal character, Tessie, bought humor to the setting which gave a light air. But it wasn?t until Tessie made a scene when her husband Roberts 2 selected the winning ticket that we begin to see the plot turn negative. Most people would be happy to win the lottery. But knowing death is the outcome, it is understood why she would be against her husband choosing the slip that he did. Although the setting is pleasant from the start, it is not until the end of the story that you realize every small detail has significant meaning. When Mr. Summers asked for assistance with the box, there was a hesitance from the men. It seemed as if no one wanted to disturb the traditions in the box used to hold the lottery and jinx their chances of winning by touching it, but they simply felt as if they were assisting fate in their own possible death. Tessie showing up late was a normal incident. It is easy to lose track of time. But she was reluctant to come for fear of her destiny. The boys were gathering stones for what was assumed to be child?s play, but, in the end, aided in murder of an innocent woman. Even the comment that was made about the how soon the lottery came back around showed that the townspeople did not truly welcome the lottery. They were able to behave in such a normal manner during this event because they accepted it. The lottery was expected and destined to oc cur, despite the opposition of the townspeople.

3 Lessons Freelancers Learn from... Bears

3 Lessons Freelancers Learn from... Bears Things that are great about being a bear: You get a diet rich in fish, you’re big enough that most predators don’t bother you, you don’t have to have a LinkedIn Profile, and when you want to go sleep in cave for weeks at a time, nobody thinks it’s weird. Fortunately we’re not just doomed to a life as sad hairless bear-wannabes. There are things freelancers can learn from bears when it comes to managing our work-life, as assembled by Chris over at Rags to Reasonable.Lesson 1: Hibernation ModeUnless you’ve landed a really plum long-term contract or three, odds are your workstream ebbs and flows (or sometimes even dries up entirely). This means you have to know how to match your variable expenses to your variable income- make sure you know how to get your operating costs low and manageable enough to allow even your â€Å"hibernation wages† to last you until your next big paycheck.Lesson 2: Go Where the Food IsThis lesson is both obvious a nd frustrating when you’re starting out and taking every single job that comes your way. Some of them may not be as lucrative as you wanted or as relevant to your overall goals as you hoped. Still,  you take them and accept what the market has to offer since you don’t know if there will be food (i.e. work) if you hold out for something closer to your experience.Lesson 3: Filling Your Fat StoresA positive and negative of freelancing is that when it rains it pours, if you’re paid by the project and not hourly. This means you may work for a while in obscurity and then (sometimes months later!) are  rewarded with a significant check for a large portion of your work.The most valuable tip I took away from Chris’ bear-advice was to remember that check is  not disposable income; it’s not leftover, it’s not actually a reliable, regular paycheck. Make it last as long as possible by being savvy with your spending and strategic with your saving.If You’re Freelancing, Have a Plan For Your â€Å"Hibernation† SeasonIf You’re Freelancing, Have a Plan For Your â€Å"Hibernation† Season  Read More at Rags to Reasonable

The Viewpoint assignment Essay Example | Topics and Well Written Essays - 500 words

The Viewpoint assignment - Essay Example The relationship between the United States and Japan had been a complicated mix of completion, cooperation, and conflict. This began in 1853, immediately Commodore Mathew Perry came to Edo Bay and insisted on a termination to over a couple of years of Japanese isolation. Only ten years prior to this, Britain had imposed Nanjing unequal treaty on China following the First Opium War (Doyle & Xiaoming 78). The disposal of Perry’s naval power convinced leaders in Japan to sign the Kanagawa treaty of 1854 that provided for the opening of two ports to ships from the U.S. The first U.S minister to China, Townsend Harris, negotiated extra agreements to extent the rights of the United States to Japan. Thus, the U.S had showed to Japan how economic weak points had left it helpless. The Chinese were further disgraced by having to surrender legal authorities over the foreigners that resided in their nation and the port cities. The Chinese citizens were even forced by the treaties to give way to Christian missionaries from the West to proselytize in the interior parts of China. Hostility to such foreign dictations forced a rebellion that re-established the Meiji emperor and commenced rapid industrialization and modernization in which leaders in Japan borrowed and learned from foreign countries, especially the U.S. The ability of the Westerners to inflict their economic demands on China forcibly was too harsh to the Chinese perception of themselves as an extremely developed civilization. In addition, the Western concept of a structure of international relations carried out among supreme nation-states challenged the identity of the Chinese as universalistic, advanced civilization. It was also hard for the courts in China to adapt to a system that had developed in the West by the 1800 where supreme nation-states interrelated as equals (Doyle & Xiaoming 90) The intellectual history of the Qing dynasty in the late 18th century shows how

Effects of hoarding on market prices Essay Example | Topics and Well Written Essays - 750 words

Effects of hoarding on market prices - Essay Example As a basic economic rule, whenever a supply of a particular item is less than the quantity demanded, the former puts inflationary pressure on the price of the goods and prices increase, if the quantity supplied could not match the quantity demanded. This can be shown through pictorial representation: The above diagram shows how hoarding affects the equilibrium condition in the market and increases the market prices. If we explain the above diagram, we can easily see that the Indian food is at a point e, where demand and supply equal at market price p1 and at quantity Q. However, as soon as the hoarding activity, this results in supply curve being shift to s1 from initial supply curve of S. As a result of this a new equilibrium is formed at the point e1. At this point the quantity is below the initial quantity of Q at Q1. (Sloman, 2004) Similarly, due to this a shortage has been created and people with more money are ruling the market by the virtue of being able to pay higher prices. As a result the market price of food items increases high and now the food stuff is available at a higher market price of p1. As a result this hoarding decreases the supply and increases the market prices. ... Now, let's assume that at the time when hoarding activities are going and due to poor crop the going market prices are set at the price p. However, due to effective government action against hoarders and release of buffer stock into the market, the supply of food items in the market will now increase to a new supply position of Se. We can clearly see that Se is rightward of the supply curve at the time hoarding that is Sh. This shows that the supply in the market has increased. This increase in supply means that there is more food stuff now available in the market at quantity Qe. This will reduce the market prices from previous prices which at the time of hoarding were at ph to pe. This analysis clearly shows how effective action by the government against hoarders can reduce the market prices and bring inflation of food items under control. Thus, we can assume that the article is suggesting the right ploy by which the Government of India can bring prices under control. (Clermont, 200 9) Another issue that has been raised in the article is how India is using measures to reduce their trade deficit by introducing export benefits for businesses in India which will increase their competitiveness in the international market. This means that government will give them tax holidays. As a result of which cost of production in India will reduce which will lower the prices of "Made In India" products. As a result of which imported goods for Indians will become expensive and hence Indians will prefer domestic production and hence reduce imported goods. This will means that India will have a lower cash outflow and hence this will improve the foreign trade situation in India.

Analysing Differences Between Different Party Systems Politics Essay

Analysing Differences Between Different Party Systems Politics Essay Why are political parties important for a democratic society? What are the different political consequences of one party system, two-party system and multi-party system? In modern societies, political parties seem to be an indispensable part in almost every country. A political party is a group of people organized to seek influence in government policy and for the purpose of winning government power, by nominating their candidates in electoral and other means. In a democratic society, a political party is on the input side of a political system, that is, the demands and interests of the people are collected from political parties and analyzed by the government before any policy decision is made. E.E. Schattschneider (1942), a political scientist, did a comprehensive research over party politics, concluded that political parties created democracy, and modern democracy is unthinkable save except in terms of parties. To a certain extent, it is impossible to run a democratic government without the help of political parties as they have quite a lot of important functions to the government. The main function of political parties is to ensure a two-way communication system between the government and public. Public opinion has long been of vital importance to democratic governance. And political parties, under this circumstance, act as a bridge between government and public. Public opinions would be collected by political parties. Different viewpoints from the public would be delivered to the government after the integration of opinion and moderation of differences by political parties. As a result, different people can be brought together so that they can compromise and reach a consensus for policy making, which in turn create a more democratic and harmonious society. Another function of political parties is to bring aggregation of people of different interests. Apart from political parties, it is not uncommon to find interest groups in the society, which simply want to promote their groups interest and inform the public of it. However, chaotic and unstable government would be resulted if interest groups became the highest form of political organization. As interest groups would mainly focus on their needs and have conflicts with each other easily, it is difficult to set comprehensive goals or values in policy making. Political parties, in this situation, help pulling interest groups into a larger organization. In doing so, interest group conflicts can be calmed and settled by interest aggregation. Therefore, many large political parties nowadays, such as the Democratic Party in the United States and the Labour Party in Britain, are coalitions of different interest groups. Integration of different new groups into political system can also be done by political parties, especially for integrative parties, which attempt to mobilize, inspire and educate the public instead of only responding to public concerns. Political parties usually welcome new groups join in and provide them support by giving them educational opportunities, welfare benefits and so on. In doing so, members of the group may feel represented, thus develop a sense of belonging and loyalty to the political system. The U.K. Labour Party and German Social Democratic Party would be related examples. Labours in the above parties are integrated successfully into the political system and learnt to strive for their needs by democratic rules. On the contrary to countries where integration of working class into the political system was failed, radical movements might easily be resulted. After integration into political system, political socialization is essential for transferring knowledge of the political system and social concern to the people. Political parties provide political values and factual assumptions in politics. For instance, they teach their members to organize meetings, speak in public and influence government policies. Through these teachings and trainings, the public can form positive attitudes, values and beliefs which sustain the political system As a result, members can be politically conscious and get more involved in politics. Political parties can also be the training grounds for leaders through political socialization. As a result, citizens can be represented by the educated officials and democracy can be achieved by bringing public opinion in the government. Apart from the aforementioned, political parties act as a monitoring tool to the government. As party members can be part of the government after winning elections, they can oversee the government by participation. And they can bring peoples voice in and suggest alternate policies and choices to the government, then hold the government to be accountable and responsive. Once the government has done something wrong that would harm the citizens, political parties can immediately voice out the opposition. Under this situation, it would be relatively harder for the government to ignore public voices and thus achieve a more democratic society. From the above mentioned, political parties serve a number of vital functions to create a democratic society. Political Parties, as a communication channel, facilitate the interactions and understanding between the government and the citizens. Peoples demands can be effectively transmitted to the government. To achieve real democracy, other aspects, such as honest and well-informed press and a stable party system, are other important factors as well. Nevertheless, political parties are the most direct way to influence government policy-making. Without political parties, the government may be loosely organized and peoples opinions would hardly be reflected. Therefore, political parties are necessary for the advancement of democracy. Political parties operate within party systems, and the type of system will have profound effects on party behavior. Party systems are the interactions of different political parties. There are three types of party systems briefly, which are one-party system, two-party system and multi-party system. By definition, one-party system has only one party dominates the political system. According to Almond, one-party system can be divided into three types. The first type would be authoritarian party system. Under authoritarian party system, there is only one party controlling the interest aggregation and articulation. There is no other competition for political powers, and opposition is suppressed and disallowed. Another type is totalitarian party system. Under this system, only one party has the legitimate right to govern. No competition for political powers is allowed. Party uses indoctrination, highly emphasizes people interest and party interest should be equal. The system uses the official ideology to mobilize the mass so as to gain political support. For instance, China was under this party system and used mass campaign, such as the Cultural Revolution to mobilize people. In modern society, it is believed that North Korea is one of the remaining countries that is still under this totalitarian party system. The last type is dominate non-authoritarian party system. This system exists with only one strong party. Even though other parties are permitted to exist in the country, they are not strong enough to challenge or compete with the dominant political party for power. As a result, practically, there is only one party in power. Take the example of the Peoples Republic of China (PRC), a system called multi-party cooperation under the Chinese Communist Partys leadership has been developed. That is, there are at present eight so-called democratic parties in China apart from the Communist Party. However, these eight other political parties, such as China Democratic League, China Association for Promoting Democracy and Jiu San Society in the PRC are only under the leadership of the Communist Party. At the end, the only party that matters and gains the power is the Communist Party. No matter which type of the one-party system does the country follow, various political consequences might likely be resulted. Decision making under one-party system is efficient. As there is only one party in power, other viewpoints need not to be concerned much. Without public consultation and discussion process, swift changes or decisions are likely to be made. Take China as an example, the Communist Party holds all political power and has the exclusive right to legitimize and control all other political organizations. As a result, the Communist Party, alone, determines all the social, economic and political policies and goals for society efficiently without too much hesitation. Nonetheless, corruption would be possible as there is no checks and balances in the country. No out party is there to supervise in party. Even there are other parties in the state, they are too weak or ineffective to challenge the political power. And as there is only one party who gains the political power and controls the government, politicians would have a low risk to be prosecuted, punished, or to lose their seat. As a result, it may be relatively easier for them to take bribes. In the long run, corruption under one-party system can undermine public trust towards the whole political system and government and threaten the viability of democracy. Moreover, political apathy may be caused due to only one party in power. No matter how people express their point of views to the government, the political party may only focus on its narrow point of view, not accepting others. In some countries, such as China, would even have censorship to control peoples freedom of speech, preventing them from expressing opinions harm the partys governance. As time passes, people may feel themselves as incapable and powerless in politics, led to the cause of political apathy. Apart from the one-party system, two-party system is adopted by some countries nowadays as well. It is a competitive system with two major political parties dominating the system and competing for power. Other political parties are allowed to exist under the two-party system, but they are not strong enough to challenge the two large ad well-supported parties under most situations. Usually, the two dominant parties hold equal power, having an equal chance to win the general election depending on their previous performance. The United States of America is one of the countries adopting the two-party system, which the Republican and Democrats are the major two parties in the country. With two strong parties in the system act as opposition party, the governance may be relatively stable. There would be checks and balances between parties and the government. Unlike the situation in one-party system, the political ideas would be relatively diverse as the two parties do not incline to only one and narrow standpoint. And the two parties may ensure the government is responsive and responsible towards peoples need and concern. Although the opposition from the two parties ensures the government is responsive and responsible, several political drawbacks may be resulted. The political views from the two parties might vary a lot. Take the two-party system in the U.S. as an example, within each party, there are moderate republicans or democrats and extreme republican or democrats. For moderate republicans or democrats, sometimes they may express ideas based on their views but not following the party lines. For extreme republican or democrats, as they need to distinguish themselves from the other, their political views may become more and more extreme and two-sided, and lead to the rivalry of partisan politicsmay lead to rivalry of two parties like partisan parties may lead to rivalry of two parties like partisan parties. The great variance on political viewpoints within a party may cause confusion to the citizens. And if the views are too extreme or mostly only divided into two standpoints, it may be hard and t ime-consuming to have consensus between two parties on certain policy and peoples choice on policy making may possibly be limited. In addition, it may discourage independent or third-party candidates due to low winning chances in elections. For example, in the U.S., people have tried to set up others parties, such as the Green Party. Ralph Nader, a person who was not from the two major parties, was one of the president candidate in 2004 election. However, candidates like him simply have no chance of winning in the election, so it is hard for them to survive. Under this circumstance, in long term, new political ideas and opportunities of participation may be limited, as the major parties may be too stuck in their ways, affecting policy-making quality. The last type, the multi-party system, consists of two or more major political parties with equal strength, but none of which can win majority votes and the general election. A coalition government can be resulted, which composed of the two or three parties that win the largest number of votes or seats in the legislature. The existence of a multi-party system reflects efficient aggregation and expression of minority interest within the society. Parties concerning minorities may also get the chance in winning elections and thus the related viewpoints can be brought in various policy discussions. Under this system, a willingness to compromise and cooperate may be shown. However, this system is often criticized to be unstable. As there are many different political parties holding different political platform, values are extremely diverse, they may not be able to keep government in power for long. Germany Parliamentary election, with parties having extreme diverse values, in September 2005 showed as an example of unstable multi-party system. Besides, Italy and Israel, with multi-party system, has had years of diverse politics. And the coalition government under the system is inherently unstable, since when a party withdraws from the coalition due to internal conflicts, the government will no longer enjoy majority support from the legislature. Instability, to both the government and citizens, is non-beneficial. In long-run, citizens may lose confidence in governance. To conclude, each political system has its own political consequences, with merits or demerits. In modern democratic society, checks and balances are of certain importance in the government and any political system. Therefore, one-party system may not be preferable for a countrys governance. For two-party system and multi-party system, it is hard to conclude which is better, and there has been even a middle ground version of these two systems- two-plus party systems. But anyway, as long as parties can effectively use their power and represent public opinion, a stable and moderate party system can be established. And this, in long run, can make democracy possible.

Broadcasting Quality

Broadcasting organizations exist basically to communicate to people. Whether radio or TV stations are Government, Commercial or Private, whether programmes are spoken word, music, commercials or community announcements, in all cases the message needs to get through. The emphasis in programmes must always be on quality, both content and sound. Staff engaged in program presentation need to be conscious of making the broadcasting system seem to be transparent to the audience. Listeners and viewers should only be aware of the actual program and not the ‘nuts and bolts' of the radio and / or TV station.In order to ensure High Quality Broadcasting, a Broadcaster or Broadcasting company should by all means be instrumental in enhancing our understanding of the world – To inform its audiences and arm them with a better understanding of the world through news, information and analysis of current events and ideas. It is a function which comes hand in hand with the Stimulation of kn owledge and learning, since the content should be of capable of stimulating its viewer’s interest in the knowledge of arts, sciences, history and other topics through content that is accessible to its projected recipients and can easily encourage informal learning.Representing diversity and alternative viewpoints is by all means also a component of responsible quality broadcasting. It is one its main purpose to make people aware of different cultures and alternative viewpoints, by showing programmes that reflect the lives of other people and other communities. One of the major influences affecting broadcasting would be the existing Socio-Economic factors. Economic components have long played a key role in public policy toward broadcasting, not only where private commercial systems dominate but also where there is a public funding mechanism.Major national public service broadcasters are large programme production industries that collectively represent a substantial capital and operating investment. Many of them have had commercial support, and no matter how â€Å"non-commercial† the production distribution-reception process, it is usually closely associated with (and profits from) a substantial private, profit-oriented industry that manufactures receiving sets and electronic equipment.But broadcasting’s direct contribution to the gross national product has been modest, especially when compared to most societies† major sources of economic activity (Blumler, 2000; 26). In the field of digital television broadcasting, North America has been some years ahead of the rest of the world in its faith in what could be done with very powerful image compression systems. The open decision–making process which has taken place in the United States for advanced television (ATV) is a considerable achievement, and a great credit to the many individuals involved.In Europe, considerable expertise has been accumulated in image compression and digit al modulation, but a range of factors and circumstances have influenced the profile given, until recently, to studies of digital terrestrial television broadcasting. These have included pessimism that the planning environment in Europe would allow the development of digital high definition terrestrial television with reasonable coverage, and pessimism that sufficiently attractive picture quality could be achieved with the bit–rates that are possible in terrestrial networks.Today there is clear recognition in Europe that we must pursue quality digital television broadcasting, that we should be undaunted with the problems, and that we should explore the potential solutions, this is because the prize for success w ill be considerable. An international committee, the European Launching Group (ELG), has been established to try to coordinate the various projects which are developing digital terrestrial television broadcasting, or indeed related systems, in Europe.This committee has a technical subcommittee, the Working Group on Digital Television Broadcasting (WGDTB). The WGDTB has examined the aims of the current collaborative projects, and their timescales, and looked at the potential uses of digital television broadcasting. They arrived, at the end of 1992, at a work plan, intended to make it possible for Europe to achieve common standards for digital television broadcasting within the next few years (Altschull, 1984, p 112).European centered on the development of modulation systems appropriate for digital terrestrial television centered on the development of modulation systems for 20 GHz digital satellite television centered on the development of digital HDTV satellite point–to–point systems developing all aspects of digital terrestrial television developing all aspects of digital terrestrial television developing base band coding systems continuing studies of terrestrial and satellite planning, requirements and testing present article will outline some features of this plan, and give the background to the conclusions reached (Anand, 1993, p 156-210).What the WGDTB has done is to develop a first scenario which needs now to be taken up by experimental work. A fundamental limitation on the quality and ruggedness of terrestrial television services will be the terrestrial channel capacity. In Europe, the VHF/UHF broadcast television bands use either 7or 8 MHz channels. The working assumption has been that the system should have a bandwidth of about 7. 5 MHz. The prospect of using more than one channel in a contiguous way for a single broad-cast service seem remote, and the prospects of obtaining new frequency allocations with a wider channel spacing, even more so.Given a 7. 5 MHz channel, it seems that the upper bound on gross bit rate is likely to be about 30 M bit/s. The first task the WGDTB undertook was to evaluate the options which seemed most likely to be attractive and saleable to the European consumer in the next c entury, in the light of what could be seen, or predicted, as general trends in society (Anand, 1993, p 156). There is no doubt that the quality expectations of viewers are rising, and that the long–term future of television lies with HDTV. Nevertheless, the Group was also conscious that viewing habits are changing as society evolves.Therefore, when setting system goals there are dimensions other than quality which need to be taken into account (Briggs, 1999, p 145). It is not sufficient to ask what the public may want, we also need to ask when and where they will want it. Furthermore, the practical large flat–screen HDTV display, for many years regarded as the key to HDTV acceptability in the domestic environment, seems nearly as far away as ever. One underlying trend in society is toward individual activity, rather than group activity. A second element to consider is mobility.Essentially sound–radio has migrated from a group experience in the home, to a nearâ⠂¬â€œindividual activity in the car. We could reasonably ask if some of the same evolution will apply to television to any degree, orate least whether television will also have to cope with a mobile environment. There seemed to be four options, essentially linked to different viewing environments, which were worthy of most attention. The options are as follows:– HDTV (high definition television), which offers services to viewers with very large screen receivers, using fixed roof–top aerials.– EDTV (extended definition television), which offers services to viewers with medium to large screen receivers using fixed roof–top aerials. – SDTV (standard definition television), which offers services to viewers with portable televisions using set–top aerials. and LDTV (limited definition television), which offers services to viewers with small screen receivers using whip/stub aerials in a mobile situation (e. g. in acre). In order to translate these concepts to practical sys-teems, it is necessary to decide what is meant pre-cicely by the quality in each case, and what is meant precisely by each of the receiving environments.Picture quality is difficult to quantify in absolute terms, because it is the net effect of a series of factors such as resolution, sharpness, noise, artifacts, etc. It is by no means only related to the scanning standard. The picture quality that is achieved will also be related to the source quality, the sophistication of the compression algorithm, and the bit rate used. The receiving environment can be defined some-what more easily. It is related to the bit–error distribution in which the system is required to work. In other words, it is associated with the ruggedness necessary to achieve impairment–free pictures of the intended quality.As a first assumption in the WGDTB, the roof–top environment is considered to be associated with a spectral efficiency of 4 bits/s/Hz. The portable e nvironment is considered to need 1–2 bits/s/Hz, and the mobile environment is considered to need 1 bit/s/Hz. 2. REVIEW OF RELATED LITERATURE A. The Dimensions of Picture Quality Color Television was initially conceptualized in the 1950’s. Back then, a single color picture requires three images, specifically red, green, and blue (RGB) for light emitting devices such as cathode ray tubes (CRT).This would require a 30 MHz bandwidth to provide the desired picture rate, starting from the full progressive scan picture. To reduce the bandwidth to 15 MHz for an analog RGB system, an interlace is used. Within a studio the signals are carried on three separate cables at 5 MHz or more bandwidth each, a fundamental compression scheme used in color television is to translate the three color signals into the color-difference domain where the picture is represented by a luminance (equivalent to the earlier monochrome) picture and two color difference pictures, R-Y and B-Y.Another nam e for this system is YUV, Y for luminance and U, V for the two color difference signals. Again using the limitations of the human visual system, in this case less color than luminance visual acuity, the bandwidth of the color difference signals is reduced by 50% for a total YUV bandwidth requirement of 10 MHz. Today, YUV signals are used in both analog and digital forms and have very little visible degradation compared to interlaced RGB video. Both forms are known as component video with YUV being used for most applications.Nowadays, there are two reasons to compress television video signals, practical limitations of processing speed (bandwidth) and cost of transmission or storage resulting from the required bandwidth. Today, the availability of high speed semiconductors and integrated circuits make the latter reason most important in nearly all applications. Virtually all video compression methods utilize the limitations of the human visual system to remove the less visible picture information that might otherwise be present.As broadcast television was being developed, display rates of 50 or 60 pictures per second were considered necessary. Discussing Quality Broadcasting and its future would not be complete without discussing the past and present of Broadcasting. Cathode-ray tube, also known as CRT’s is the technology used in most televisions and computer display screens. A CRT works by moving an electron beam back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots on the inside of the glass tube, thereby illuminating the active portions of the screen.By drawing many such lines from the top to the bottom of the screen, it creates an entire screenful of images. The technology used for the display is also a critical part of the quality equation, and all broadcasters currently suffer from a lack of flat panel monitors which can be used to check that picture quality is perfect before it l eaves the studio. The reason is because display are no longer made using ‘CRTs', which had many disadvantages, but could be made as very high precision instruments when needed.This is not so easy with today's flat panel display. An analysis of the options available for a common multiplex is currently being made. There seem to be a number of potential candidates for a common multiplex, and particular attention unfocussed on the MPEG proposals and the DAB system. A unique system for DAB and Devisees particularly attractive. a. ) HDTV Nowadays, we have different prototypes of devices which we use to enhance broadcast information quality with.One of these numerous devices would be what we call HDTV which is also known as High-Definition Television. This is basically a new television prototype that provides much better resolution and resonance than current televisions based on the NTSC standard. HDTV is a type of Digital Television (DTV) broadcast, and is considered to be the best quality DTV format available. Types of HDTV displays include direct-view, plasma, rear screen, and front screen projection. HDTV requires an HDTV tuner to view and the most detailed HDTV format is 1080i.HDTV is a digital TV broadcasting format where the broadcast transmits widescreen pictures with more detail and quality than found in a standard analog television, or other digital television formats. High definition television is defined rather loosely by the International Telecommunication Union (ITU) as a system which has about twice the horizontal and vertical definition of conventional television. This still leaves open the amount of noise or artifacts that are permitted, and which affect the picture quality just as much as definition.In Europe, Asia, South America and across other parts of the world the PAL system is adopted by each state, and often with some unique characteristic, such as the location of the sound carrier. This means for protecting sovereign borders has made f or complications in program exchange, though presumably has not impacted the set sales in any of the regions. Further-more, there is a relatively wide range of definitions available within the term â€Å"conventional television†. In addition, interlaced systems have a triangular vertical–temporal response, so it is difficult to know where the concept of â€Å"twice resolution† applies (Anand, 1993, p 210).To pin down HDTV, we have to look at the combined effect of all the quality factors on the picture; and, to some extent, make up new rules. It is apparent that the NTSC standard sets the limits today in television quality. The NTSC system is a composite system, meaning the color or chrominance information is embedded in the luminace information. In over-the-air and cable transmission there are frequently micro reflections produced, which deliver somewhat delayed second or third harmonic images (which are commonly referred to as ghosting).Only so many scanning l ines, so much bandwidth is in the standard. There is also the inclusion of interlace scanning, producing aliasing artifacts, interline noise (often called â€Å"twitter†), and dot crawl which is undeniably the factor which makes perfected separation by way of comb filtering of color and luminance information very expensive, thus color smearing results in most modestly priced sets without this device included. The accumulation of artifacts from the traditional NTSC standard has placed a practicalsize limit of the television image since most consumers perceive an increase in size as a â€Å"cause† of the artifacts, rather than merely the exposing of them. While filtering techniques have improved, the cross color and dot crawl artifacts, there remains the unalterable fact that the total amount of picture information in the broadcast standard has a specific limit. When deciding on a required picture quality we have to bear in mind the target viewing distance, and the need to ask, responsibly, for no more than is necessary.Digital compression systems all work in a similar way. The information content of the source picture varies from scene to scene. The system reproduces the content of the input picture essentially intact, until the point is reached where the transmission bit–rate will be exceeded if nothing is done. At this point, a series of approximations are made to parts of the scene. The output scene can thus have (apparently) added noise or loss of resolution, to an extent depending on the original scene content.For any practical system there will always be scenes which are reproduced perfectly, and others which are impaired. The system designer’s intention is to make the impairments occur as infrequently as possible, and be as unobtrusive as possible. The main approach examined by the WGDTB to specify the quality needed is termed the â€Å"scene–content failure characteristic†. This is a logical and scientific metho d, but it is also relatively ex-pensive to use.The basic element to be specified is the proportion of total programmed time which should be free of artifacts. â€Å"Freedom from artifacts† is considered to be associated with a minimum mean score of 12% in a double–stimulus continuous–quality scale (DSCQS) subjective evaluation. This is somewhat arbitrary figure, but much experience shows it to be a good rule of thumb for virtual transparency. The challenges are then, first, to decide what constitutes a sensible proportion of time for which impairment free pictures should be demanded.The second challenge is to assemble statistical evidence about the relative occurrence of different kinds of scene content, so that it can be verified that the requirements are met. In choosing the proportion of time for which impairment–free pictures could be expected, we can look to the other â€Å"statistical† domain of picture quality, which is the propagation failu re characteristic, used as a planning criterion. For example, in broadcasting satellite systems (BSS), quality is required to be maintained for a defined percentage of the worst month of the year.If this kind of guide-line is acceptable for satellite systems, would it also be acceptable for terrestrial television broad-casting? Unfortunately, the answer is â€Å"not quite†. In satellite broadcasting, the â€Å"outage time† is used up in rain–fades, which occur over a period of, say, half–an–hour. The quantization–noise artifacts that are introduced by digital coding will probably be more spaced out than this, and their effects will therefore be less severe on the viewers overall perception of quality (this is sometimes called the â€Å"forgiveness effect†).However, it may be appropriate to adopt a value similar to that for the BSS as a starting point for fixing the scene content failure characteristic requirement (Anand, 1993, p 210). The WGDTB has tentatively begun by taking 99. 7% transparency as the requirement for the dig-ital terrestrial HDTV service. Coupled with this, it is assumed that the reference quality is a1250/50/2:1 HDTV studio signal, with 1440 samples/line. We do not yet have a catalogue of HDTV picture sequences and their places on a code â€Å"criticality table†, but we do have some experience from for-mar 4:2:2 code studies (Altschull, 1984, p 112).These suggest that to achieve the target transparency, the code would need to pass, unimpaired, almost all the test pictures so far devised, including the second most–stringent CCIR sequence â€Å"mobile and calendar†(critical, but even so only in the area of 80%–90%criticality). The quality target is very high, and may not be achievable at the available bit–rate. But it certainly is worth aiming high at the start. It is known from past experience that HDTV source and display equipment quality will improve, and a system which will last well into the next century would be valuable.The next key question is â€Å"what quality can be achieved with 20–30 M bit/s? † Initial tests may be possible in autumn 1993 with the HD–DIVINE system, and these would probably provide first clues. b. ) EDTV The second quality level to be discussed is termed EDTV. EDTV is a common name for a particular subset of the DTV (Digital Television) standards, but On a large display screen only. It is also known as Enhanced Definition Television or extended definition television. EDTV is considered to be specifically a part of the HDTV format but does not fall near the quality and performance of HDTV.EDTV as a whole can only simulate HDTV viewing quality. However, The EDTV prototype offers more technological advancements over the SDTV unit. EDTV operates as 480p (where 480 represents the vertical resolution and p represents progressive scan). To take advantage of the said 480p standard, video source th at outputs that signal (i. e. a DVD player) must be used and the display must be able to read the 480p input signal. As an additional feature an EDTV unit also offers the benefits of Dolby digital surround soundThis is not a particularly appropriate name, because the scanning standard for the system would be the normal625–line system. The level is included because large–screen HDTV receivers, which have an HDTV dot pitch, will be very unwieldy and very expensive for many years to come. An EDTV level would fulfill a need for a lower–cost and lighter receiver. Having probably a screen size less than about 30 inches, it would not be dramatically inferior to an HDTV display in perceived quality. There may also be living rooms which are not large enough to take a true HDTV receiver.The source format for EDTV is assumed to be a signal conforming to CCIR Recommendation 601, with 720 samples per line and a 16:9 aspect ratio (Starks, 1993, p 196). The codes transparency required, in terms of the percentage of program time unimpaired, would be roughly the same as for the HDTV level (al-though in this case with respect to the 4:2:2source). The best information available at the present time is that in order to achieve this level of transparency, a bit–rate of about 9–11 M bit/s is probably needed for a motion–compensated hybrid DCT system.c. ) SDTV The third quality level considered is SDTV,. Short for Standard Definition Television it is a type of digital television operation method which is able to transmit and produce images which are of a higher quality than standard analog broadcast. While SDTV does not reach near the quality of HDTV, it is definitely superior over traditional analog television. SDTV is typically a 480i signal – where 480 represents the vertical resolution and i represents interlaced. Digital cable and digital satellite programming is widely available in SDTV format.This is specifically intended to mat ch the quality needs of portable receivers. On small–to–medium screen sizes, even today’s PAL/SECAM quality is very good. Thus, for the SDTV level, a system which has a625–line scanning format is needed, but some artifacts can also be accepted, as is the case for both PAL and SECAM. The kinds of artifacts associated with PAL/SECAM and a digital motion–compensated hybrid DCT system will be different, but it is believed that in order to achieve, globally, about the same over-all quality, a data rate of about 5–6 M bit/s is needed. d. ) LDTVThe fourth quality level is LDTV, limited definition television. This is intended to match the needs of very small screen receivers, which might be used in cars, and now being incorporated to mobile phones as well. The quality requirements of this level would be about the same as the MPEG 1 codes or about VHS level. Specifying the quality requirements, and evaluating the systems in terms of their sceneâ€⠀œcontent failure characteristics will be a major technical challenge, principally because of the need to establish how often scenes of a particular type of content are likely to occur.There may be alternative simpler approaches which will also help to understand and quantify the systems’ behavior. Another potential quality evaluation criterion, which the WGDTB has been asked to consider, is associated with the concept of â€Å"quality space†. Our perception of the picture quality of a given system is directly influenced by the viewing distance. The further from the screen, or the narrower the viewing angle, the less discriminating we are in terms of resolution or artifacts.One way, therefore, to see the various quality levels, is by imagining that there is a â€Å"quality space†, which is a graphical representation of picture quality–versus–viewing distance. For the picture quality axis, we use the same axis as for DSCQS evaluations (Andersen, 199 0, 291). There are five contiguous and equal intervals characterized by the quality descriptors: excellent, good, fair, poor, and bad. Similarly, It was specified by the EDTV system as one for which the results of assessments must fall in the excellent band at 4H.SDTV systems are those for which the results must fall in the excellent band at6H, and an LDTV system as one for which the results must fall in the excellent band at 8H. This seems a relatively clear means of defining and distinguishing between the quality levels, but experimental work remains to be done to establish its viability in practice. DISCUSSION A. Impact of Source quality Another interesting dimension to this question of picture quality concerns the impact of source quality on final picture quality under high compression.Compression systems may show a characteristic such that it could be considered (in a simplified way) that their characteristics of quality–versus–bit–rate have two regions. A Camcorder video compression device was recently developed to function effectively in a variety of applications and which could effectively address the need for high-resolution surveillance image recording. The said device is able to simultaneously encode two separate streaming images — full size and quarter size — with robust compression and high quality.The creator of the device, Showlei Associates has announced that its CamCoder video compression device will dramatically lower the cost, power consumption and size for the compression of high-definition streaming images. The IC also contains internal logic for user-programmable motion detection and watermark insertion, as well as on-board memory. High definition compression systems, as available today, do not perform as well as predictions made several years ago, with the exception of the newly created device – but the next years should bring maturity and allow more complexity in equipment.E It is a common conse nsus that the full benefits for broadcasters of the new advanced compression systems would be achieved eventually. However as of the present time inventors are still finding a way to get pass one of the quality defects of digital broadcasting today, this problem is the lack of synchronization between vision and sound. Achieving this may even become more difficult with more advanced codes. This still needs to be carefully evaluated by all broadcasters to find any loopholes in the said device. ConclusionThe Quality of Broadcasting is by all means generated by a combination of both responsible dissemination of information and state of the art broadcasting equipment. The way in which information is disseminated and retained by the audiences would first and foremost be the determining factor as to effectiveness of the broadcasting being done. The content plays a very important role in keeping the interest of the audience and it should be discerned that without a substantially good topic, even the most advanced equipment to disseminate information would not be a factor at all.It is in this context that commitments must soon be made and it is to be of utmost importance that all administrations and organizations which will be affected by technological changes should be able to share in the accumulated understanding of the factors involved with a view to taking carefully considered decisions. To assist in this process, the ITU/BR has convened a Workshop Tomorrow’s television – Thaw IDER picture, with the support of the European Broadcasting Union and the Asia–Pacific Broad-casting Union.It aims to bring together the expertise necessary for a common understanding of the issues and, to allow a balanced representation of all contending systems, the Workshop is being held away from the main centers of study, in New Zealand.
