This article discusses the current economic importance of fresh water algae and possibilities of exploitation of algae in the future. Desirable and undesirable aspects are considered and illustrated with examples mainly from South Africa. The excessive development of undesirable algae in freshwater adversely affects the water quality by a number of chemical changes which can vary from tastes and odours to production of substances that consitute a threat to human or animal health. Removal of unwanted algae adds considerably to the costs of water treatment. Excessive algal growth impairs recreational activities and affects shoreline property values.

Electricity Access

High rates of customer default on utility bills present a barrier to the expansion of electricity access in the developing world. Pre-paid electricity metering offers a technological solution to ensuring timely payment. Using an eleven-year panel of pre-paid electricity customers in Cape Town, South Africa, we describe patterns of purchase behavior across property values, our measure of socioeconomic status. Poorer households buy electricity more often, in smaller increments, and are most likely to buy on payday. These patterns suggest difficulties smoothing income, and reveal a preference for small, frequent purchases that is incompatible with a standard monthly electricity billing cycle.

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.
