The demography of micro-states

There are two types of micro-states, islands and mainland ones. Except for a few islands very close to the coast, most of the insular micro-states are demographically very different from the rest of the Third World. Their death-rates are lower, their birth-rates lower, and the propensity of their populations to migrate to developed countries higher. It is argued here that these differences are based on other social and economic differences, which can be summarized by saying that such states are more Westernized. They were part of the European maritime system at a time when the West did not have the economic strength to penetrate continental areas to the same extent. On the whole they retained colonial links longer.     

Why a new malpractice crisis is coming

This article predicts escalating premiums and a greater risk of malpractice suits based on the increasing frequency and cost of claim payouts. The number of insurance claims increased by 12% in 1978 after a decrease of 11% in 1976 and by 2% in 1977. The percentage of premium income paid out has followed the same pattern. It was a high of 66.5% in 1975 and then fell into the 40% range in the next two years. Last year it bounced back to 60.6%. Some insurance authorities view the 1976-77 drop in claims as artificial and attribute it to a reluctance to file suits during the period immediately following new malpractice laws. The reluctance to sue has apparently relaxed. About 16% of the cases actually go to court. Out of those, 90% of the verdicts favor doctors. The rise in cases going to court shows that reform! legislation passed in several states to reduce malpractice litigation is not yet working. The average payout was up 20% between 1976 and 1978 with the greatest rise in large awards; million-dollar settlements are not uncommon. Escalating payouts are attributed to general inflation anf rising medical costs. In addition, the public has become better medically informed and been taught that for every wrong ther is a remedy.     

The organizational context of human factors engineering

Human factors engineering concerns the design of equipment in accordance with the mental and physical characteristics of operators. Human factors engineers advise design engineers, but the organizational context limits their influence and restricts their perspective. The discussion of organizational context in this paper explains why military and industrial top management personnel are indifferent to good human factors design and shows how the social structure favors the choice of technologies that centralize authority and deskill operators and how it encourages unwarranted attributions of operator error. The role of equipment and system design in shaping cognitive maps and mental models is explored, and the technology-social structure paradigm is questioned.     

Structural shifts in urban population density gradients: an empirical investigation

This study investigates the structural shifts in urban population density gradients by first using the shifting regression technique of Farley, Hinich, and McGuire to detect the possible change in the structure of an urban area. Secondly, a generalized random coefficient technique is used to simultaneously detect the possible structural change and stochastic behavior of density gradients. Data for 50 United States SMSA's are used to do the empirical analyses.
