Just as there are global markets for products, technology, and capital, managers must now think of one for labor. Over the next 15 years, human capital, once the most stationary factor in production, will cross national borders with greater and greater ease. Driving the globalization of labor is a growing imbalance between the world's labor supply and demand. While the developed world accounts for most of the world's gross domestic product, its share of the world work force is shrinking. Meanwhile, in the developing countries, the work force is quickly expanding as many young people approach working age and as women join the paid work force in great numbers. The quality of that work force is also rising as developing countries like Brazil and China generate growing proportions of the world's college graduates. Developing nations that combine their young, educated workers with investor-friendly policies could leapfrog into new industries. South Korea, Taiwan, Poland, and Hungary are particularly well positioned for such growth. And industrialized countries that keep barriers to immigration low will be able to tap world labor resources to sustain their economic growth. The United States and some European nations have the best chance of encouraging immigration, while Japan will have trouble overcoming its cultural and language barriers.

There have been numerous articles written on surgical reconstruction of the lateral collateral ligaments. This paper discusses a different type of lateral ankles stabilization procedure performed on 19 patients at Doctors General Hospital, with mean follow-up of 14 months. The procedure is done entirely with soft tissue; no osseous structures are involved. The authors have utilized tendon, particularly part of the peroneous brevis tendon, to reinforce the lateral capsule and collateral ligaments. It is this technique and some modifications that are presented.

The paper describes a series of experiments carried out in the laboratory to investigate how asbestos fibres might become electrostatically charged during the process of being made airborne, the magnitude and polarity of the charge per fibre, and the effect on lung deposition in rats. Measurements of the penetration of fibres through an electrostatic elutriator enabled the magnitude and distribution of charge in a cloud of fibres to be quantitatively assessed. Thus it was found that a typical fibre of UICC amosite, as dispersed in a typical animal exposure chamber, carried a net charge of magnitude equivalent to about 60 electrons. The distribution of charge was bimodal, suggesting that two charging mechanisms were taking place, the main one producing net negative charge and the lesser one producing net positive charge. These were attributed to materials in the dust dispenser used and with which the fibres came into contact during dispersal. It was found that the magnitude of charge on a typical fibre could be significantly reduced by the introduction of equal numbers of positive and negative gaseous ions from an a.c. corona discharge ioniser. Finally it was found that enhancement by up to 40% of the dust deposited into the slowest clearing part of the respiratory tract of experimental rats was brought about by the electrostatic charge on the airborne fibres. The implications of this finding in the field of occupational hygiene are briefly discussed.
