Abstract P. caribaea, especially P. caribaea var. hondurensis, is widely planted throughout the American, Asian, and African tropics and subtropics. It is fast growing and has very versatile wood. P. caribaea var. hondurensis is the most productive of the three varieties of P. caribaea. P. caribaea var. hondurensis grows on a wide variety of sites in the tropics and subtropics at altitudes below 800 m (Whitmore and Liegel, 1980), although it also grows well up to altitudes of 1500 m or more. Worldwide interest has been focused on rapid-growing selections and provenances of the variety hondurensis. It has been found that var. hondurensis crossed naturally with P. oocarpa, and P. oocarpa var. ochoterenai produces progeny that have better form and are faster growers than their parents (Perry, 1991). P. elliottii crossed with P. caribaea var. hondurensis has made a major contribution to the success of commercial forestry in Queensland, Australia. These successes have also stimulated interest in hybrids in other countries such as South Africa, Brazil and Fiji.

The Status

Electrical and electronic equipment pervades modern lifestyles and its usage is growing rapidly around the world. Quick obsolescence and newer functionalities are resulting in huge quantities of these products become waste. This fast growing waste stream has been subject to regulations based on the concept of extended producer responsibility in several countries, mainly in Europe. This paper looks at the progress of legislating this particular waste stream with special emphasis on the three countries, namely China, India and South Africa, within the framework of the Swiss global e-waste programme, after looking briefly at the status of transposing the WEEE Directive (waste electrical and electronic equipment) in Europe.

The main sources of air pollution in South Africa are described together with the basic reasons fro their occurance. Also is the policy adopted by the authorities to maintain air pollution in the R.S.A as levels considered safe for mean and the environment bring mind the best practicable means philosophy of the air pollution legislation which was promulgated some 25 years ago and the need to see that a delicate balance is maintained between what is essential fo ra safe and healthy environment and what can be afforded in a developing country with a fast growing population

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.

Exchange Program

Abstract This article summarizes a series of trips sponsored by People to People, a professional exchange program. The trips described in this report were led by the first author of this article and include trips to South Africa, Russia, Vietnam and Cambodia, and Israel. Each of these trips included delegations of 25 to 50 speech-language pathologists and audiologists who participated in professional visits to learn of the health, education, and social conditions in each country. Additionally, opportunities to meet with communication disorders professionals, students, and persons with speech, language, or hearing disabilities were included. People to People, partnered with the American Speech-Language-Hearing Association (ASHA), provides a meaningful and interesting way to learn and travel with colleagues.
