Higher education, also called tertiary, third stage or post secondary education, is the non-compulsory educational level following the completion of a school providing a secondary education, such as a high school, secondary school. Tertiary education is normally taken to include undergraduate and postgraduate education, as well as vocational education and training. Colleges and universities are the main institutions that provide tertiary institutions. Tertiary education generally results in the receipt of certificates, diplomas, or academic degrees.

Higher education includes teaching, research and social services activities of universities, and within the realm of teaching, it includes both the undergraduate level and the graduate level. Higher education in that country generally involves work towards a degree-level or foundation degree qualification. It is therefore very important to national economies, both as a significant industry in its own right, and as a source of trained and educated personnel for the rest of the economy.

What is ‘tertiary education’?

"Until recently, the ‘Science of the future’ was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next breakthrough in technology will be brought about through a combination of those
two Sciences with organic chemistry and genetic engineering. This Science is the combination of biotechnology.
 Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness, and flexibility that we find in the bodies of ordinary insects.
 Nevertheless, scientists in the laboratory have already succeeded in ‘growing’ a material that has many of the characteristics of human skin. The next step may well be ‘biotech heart and eyes’ which can replace diseased organs in human beings. This will not be rejected by the body, as in the case with organs from humans.
 The application of biotechnology to energy production seems even more promising. In 1996, the famous science-fiction writer Arthur c. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic levels unless we develop power sources that are both cheaper and cleaner."

Many people believe that watching television has resulted in lower reading standards in schools. However, the link between television and printed books is not as simple as that. In many cases, television actually encourages people to read for example, when a book is turned into a TV series, its sales often go up. One study of this link examined six-year-old children who were viewing a special series of 15-minute programmes at school. The series was designed to encourage the love of books, as well as to develop the basic mechanical skills of reading. Each programme is an animated film of a children's book. The story is read aloud while certain key phrases from the book appear on the screen, beneath the picture. Whenever a word is read, it is also highlighted on the TV screen.

One finding was that watching these programmes was very important to the children. If anything prevented them from seeing a programme, they were very disappointed. What's more, they wanted to read the books which the different parts of the series were based on.

The programmes also gave the children more confidence when looking these books. As a result of their familiarity with the stories, they would sit in pairs and read the stories aloud to each other. On each occasion, the children showed great sympathy when discussing a character in a book because they themselves had been moved when watching the character on TV.

What kind of film is each program?

Instructors at American colleges and universities use many different teaching methods. Some instructors give assignments everyday. They grade homework. Students in their classes have to take many quizzes, a midterm exam, and a final test. Other instructors give only writing assignments. Some teachers always follow a course outline and usually use the text book. Others send students to the library for assignments.
The atmosphere in some classrooms is very formal. Students call their instructors “Professor Smith,” “Mrs Jones,” and so on. Some teachers wear business clothes and give lectures. Other classrooms have an informal atmosphere. Students and teachers discuss their ideas. Instructors dress informally, and students call them by their first names. American teachers are not alike in their teaching styles.
At most American colleges and universities, facilities for learning and recreation are available to students. Students can often use type-writers, tape recorders, video machines, and computers at libraries and learning centres. They can buy books, notebooks, and other things at campus stores. They can get advice on their problems from counselors and individual help with their classes from tutors. Students can relax and have fun on campus, too. Some schools have swimming pools and tennis courts. Most have snack bars and cafeterias.

Where do students call their instructors “Professor Smith,” “Mrs Jones,”?

Most of us tend to think of production when we think of mass media industries. After all, it  is the output of this production – the papers we read, the cable TV shows we watch – that grab our attention, make us happy or angry, interested or bored. Moreover, most public discussion about  mass communication tends to be about production. The latest gossip about that actor will be in what film, the angry comments a mayor makes about the violence on local TV news, the newest  CDs by an up-and-coming group – these are the kinds of topics that focus our attention on the  making of content, not its distribution or exhibition. 
Media executives know, however, that production is only one step in the arduous and risky process of getting a mass media idea to an audience. Distribution is the delivery of the produced  material to the point where it will be shown to its intended audience. The activity takes place out of public view. We have already mentioned the NBC acts as a distributor when it disseminates  
television programming via satellite to TV stations. When Philadelphia Newspapers Inc. delivers  its Philadelphia Inquirer to city newsstands, when Twentieth – Century – Fox moves its Musicland  stores, they are involved in distribution to exhibitions.

Basic to any understanding of Canada in the 20 years after the Second World War is the country’s impressive population growth. For every three Canadians in 1945, there were over five in 1966. In September 1966 Canada’s population passed the 20 million mark. Most of this surging growth came from natural increase.  The depression of the 1930s and the war had held back marriages, and the catching-up process  began after 1945. The baby boom continued through the decade of the 1950s, producing a population increase of nearly fifteen percent in the five years from 1951 to 1956. This rate of increase had been exceeded only once before in Canada’s history, in the decade before 1911, when  the prairies were being settled. Undoubtedly, the good economic conditions of the 1950s  supported a growth in the population, but the expansion also derived from a trend toward earlier marriages and an increase in the average size of families. In 1957 the Canadian birth rate stood at  28 per thousand, one of the highest in theworld. 
After the peak year of 1957, the birth rate in Canada began to decline. It continued falling  until in 1966 it stood at the lowest level in 25 years. Partly this decline reflected the low level of births during the depression and the war, but it was also caused by changes in Canadian society. Young people were staying at school longer, more women were working; young married couples  
were buying automobiles or houses before starting families; rising living standards were cutting down the size of families. It appeared that Canada was once more falling in step with the trend  toward smaller families that had occurred all through the Western world since the time of the  IndustrialRevolution. 
Although the growth in Canada’s population had slowed down by 1966 (the increase in the  first half of the 1960s was only nine percent), another large population wave was coming over the horizon. It would be composed of the children who were born during the period of the high birth  rate prior to 1957.

The movement of people towards cities has accelerated in the past 40 years, particularly in the less developed regions, and the share of the global population living in urban areas has increased from one third in 1960 to 47% (2.8 billion people) in 1999. The world's urban population is now growing by 60 million persons per year, about three times the increase in the rural population.

Increasing urbanisation results about equally from births in urban areas and from the continued movement of people from the rural surround. These forces are also feeding the sprawl of urban areas as formerly rural peri-urban settlements become incorporated into nearby cities and as secondary cities, linked by commerce to larger urban centres, grow larger.

The proportion of people in developing countries who live in cities has almost doubled since 1960 (from less than 22% to more than 40%), while in more-developed regions the urban share has grown from 61% to 76%. There is a significant association between this population movement from rural to urban areas and declines in average family size.

Asia and Africa remain the least urbanised of the developing regions (less than 38% each). Latin America and the Caribbean is more than 75% urban, a level almost equal to those in Europe, Northern America and Japan (all are between 75 and 79%).

Urbanisation is projected to continue well into the next century. By 2030, it is expected that nearly 5 billion (61%) of the world's 8.1 billion people will live in cities. The less-developed regions will be more than 57% urban. Latin America and the Caribbean will actually have a greater percentage of inhabitants living in cities than Europe will.

Globally, the number of cities with 10 million or more inhabitants is increasing rapidly, and most of these new 'megacities' are in the less-developed regions. In 1960, only New York and Tokyo had more than 10 million people. By 1999, there were 17 cities of more than 10 million people around the world, 13 of these were in less-developed regions. It is projected that there will be 26 megacities by 2015, 22 in less-developed regions (18 will be in Asia); more than 10% of the world's population will live in these cities, up from just 1.7% in megacities in 1950.

Music influences people in different ways or the same person differ­ently at different times. Music may seem to influence people differently. That is because people can react differently to the music. We are able to apply a choosing process to the music we hear. If someone hates jazz, then a jazz piece with a positive effect will probably not make him feel good. A happy song might appear to make an angry person angrier, yet it is not the music itself that is creating the anger; rather it is the positive effect of the music. The angry person does not want to accept the song's happy feeling: it points out his already existing anger, and makes that anger come to the surface. When a piece of music is played and we are listening to it, our body, mind, and feelings are being affected. The musi­cians of ancient cultures such as China, India, Turkey and Greece under­stood the effects of music. In fact, Pathagoras, in ancient Greece, intro­duced a whole science that concerned them. Because the musicians of these ancient cultures understood these effects, they created music that was positive, uplifting, and beneficial. Once the effects of music are better understood, the next step is to gain a better understanding of the music around us, and what effect it is actually having.

A large number of inventions require years of arduous research and development before they are perfected. For instance, Thomas Edison had to make more than 1,000 attempts to invent the incandescentlight bulb before he finally succeeded. History is replete with numerous other examples of people trying, yet failing to make inventions before they eventually succeede d. Yet some inventions have come about not through hard work but simply by accident.
In most cases, when someone unintentionally invented something, the inventor was attempting to create something else. For example, in the 1930s, chemist Roy Plunkett was attempting to make a new substance that could be used to refrigerate items. He mixed some chemicals together. Then, he put them into a pressurized container and cooled the mixture. By the time his experiment was completed, he had a new invention. It was not a new substance that could be used for refrigeration though. Instead, he had invented Teflon, which is today most commonly used to make nonstick pots and pans. Similarly, decades earlier, John Pemberton was a pharmacist in Atlanta, Georgia .He was attempting to create a tonic that people could use whenever they had headaches. While he was not successful in that endeavor, he managed to invent Coca - Cola, the world – famous carbonated soft drink.
Scientists have also made crucial discoveries by accident when they were conducting experiments. In 1928, Alexander Fleming discovered penicillin, an antibiotic, in this manner. He discovered some mold growing in a dish with some bacteria. He noticed that the bacteria seemed to be avoiding the mold. When he investigated further, he determined some of the many useful properties of penicillin, which has saved millions of lives over the past few decades. Likewise, in 1946, scientist Percy Spencer was conducting an experiment with microwaves. He had a candy bar in his pocket, and he noticed that it suddenly melted. He investigated and learned the reason why that had happened. Soon afterward, he built a device that could utilize microwaves to heat food: the microwave oven.

Who was John Pemberton?
