- 301: AIDS - What's new ?
- ... agent responsible for AIDS probably dates from the 1950s, with a chance infection of humans by a modified Simian virus found in African green monkeys. Whatever its origins, scientists surmise that the disease spread from Africa to the Caribbean and Europe, then to the U.S. Current estimates are that 1.5 to 2 million Americans are now probably HIV carriers, with higher numbers in Central Africa and parts of the Caribbean. Recapping AIDS - the facts: --------------------------- AIDS is an insidious, often fatal but less contagious disease than measles, chicken pox or hepatitis B. AIDS is thought to be caused primarily by a ... HIV viruses. Not spread by mosquitoes and other insects: ------------------------------ ------------- There's no evidence of HIV transmission by insects. Researchers report that the AIDS virus cannot multiply or survive inside a mosquito. The infection pattern in Africa - where children who are not sexually active might be expected to have AIDS if mosquito bites were a real threat - shows no sign of insect transmission. Vaccines still a way off: ------------------------- Scientists caution that ...
- 302: The Battle Against AIDS
- ... in the United States in 1984. The virus became known as HIV-1. In 1985, scientists in France identified another closely related virus that also produces AIDS. This virus, named HIV-2, occurs mainly in Africa. HIV-1 occurs throughout the world. HIV infects certain white blood cells, including T-helper cells and macrophages, that play key roles in the functioning of the immune system. The virus attaches to specific molecules ... HIV-1 and HIV-2 are more closely related to simian immunodeficiency viruses, which infect monkeys, than to each other. Thus, it has been suggested that HIV evolved from viruses that originally infected monkeys in Africa and was somehow transmitted to people. One argument against this theory is that HIV has only been found in human beings. It never has been isolated from any wild monkey or other animal species. Scientists believe HIV infection became widespread after significant social changes took place in Africa during the 1960's and 1970's. Large numbers of people moved from rural areas to cities, resulting in crowding, unemployment, and prostitution. These conditions brought about an increase in cases of sexually transmitted ...

The book describes how understanding between whites and blacks can end mutual fear and aggresion, and bring reform and hope to a small community of Ndotcheni as well as to South Africa as a whole. The language of the book reflects the Bible; furthermore, several characters and episodes are reminiscent of stories from the New Testament and teachings of Christ. Thus, Alan Paton, as a reformer and the author of "Cry, the Beloved Country", gives the people of South Africa a new, modern Bible, where he, like Christ, teaches to "love thy brother as yourself" in order to help whites and blacks overcome the fear and misunderstanding of each other. The language of the book ... be rude. "Jarvis knew this was not rudeness, for the old man was humble and well-mannered." (211) As a result of reading his son's writings, Jarvis learns about the real problems of South Africa. Most of the whites don't view blacks as real people and are unaware the problems blacks have to face. Therefore it is easy for whites to oppress blacks. In the end of the ...

- 305: Imperialism
- ... nations. These more powerful nations, including the United States, Britain, and several European countries, have in the past exploited less fortunate ones for resources, capital, and knowledge. Yet in return countries located in South America, Africa, and Southeast Asia have gained the technology and capital that, over a period of time and development, improves their quality of life. One point of view could be that imperialism results in oppression and abuse ... called the Meiji Period caused newly learned ideas to change the Japanese government, resulting in the more industrialized and prosperous country we see today. In the mid-1800s, interference by both Britain and France in Africa opened up great opportunities for all nations. Ali borrowed money from many European nations in order to better Egyptian society. With this money he created schools, irrigation, and a powerful military. This interference of European ... obtained control over Egypt and the canal because Egypt was going through a great financial crisis. This allowed European ships to pass through the canal and cut thousands of miles off their travel distance around Africa, bringing a great wealth of trade from Asia that helped all of Europe, especially Britain. This interference both improved the quality of life in Egypt and in the more powerful nations of Europe. It ...
- 306: The Civilization of Ancient Egypt
- ... increased food supplies and favored stability and centralized government. The deserts to the east and west had valuable stones and minerals and helped protect Egypt from much external attack or infiltration. To the south (northeast Africa) and northeast (Syria-Palestine), however, important kingdoms developed. Egypt traded with and exploited these kingdoms but was sometimes threatened by them. Beyond Syria-Palestine greater powers--in Anatolia, Mesopotamia, and Iran--were alternately allies and ... came via Syria and Palestine, perhaps at the time of Merimdeh's earliest phase, which shows influences from these regions in material culture also. Both northern and southern Egypt traded with Syria, Palestine, and northeast Africa throughout Predynastic times. Particularly striking and so far found mainly in southern Egypt (Nakada I and II) are Mesopotamian-style cylinder seals, pottery, and artistic motifs, but these may have come through intermediaries rather than ... works extolling the bureaucracy and advising on proper behavior were popular. Internal strength encouraged expansion and aggression abroad. In the Early Dynastic period, the Egyptians already had extensive trade contacts with Syria, Palestine, and northeast Africa; they pushed into the Sinai and northern Nubia, creating both buffer zones and Egyptian-dominated trade routes. Later, in the 4th and 5th dynasties, Egyptian armies went further, raiding Palestine and southern Nubia; by ...

When the Arabs brought the Arab language and writing system into Ghana, some Ghanaian kings even adopted ... you can probably tell that the Ghanaians lived a simple and prosperous life until taken over by the Mali Empire.
