ESR dating of the Neanderthal site, Kebara Cave, Israel

In 1985 a Neanderthal skeleton was found in the cave of Kebara in southern Mt. Carmel. Electron spin resonance (ESR) dates have been obtained on tooth enamel of gazelles found in layer X, just overlying the layer in which the skeleton was found. Assuming early uptake of uranium by the teeth, they yield an age of 60 ± 6 ka; assuming gradual, linear uptake of uranium yields an age of 64 ± 6 ka. Both age estimates are consistent with a previous estimate for the skeleton, based on TL dating of burnt flint, of 60 ± 4 ka.     

Geography and the study of Third World underdevelopment re-revisited

Progress in development geography has been recently associated with the shift of the perspective on underdevelopment from a right-wing, conservative standpoint to a leftward, liberal-radical position. Marxism often conceals its message in obscure rhetoric with moral overtones on colonialism, slavery, poverty, and underdevelopment. Liberal academics have lamely acceded to the dogmas of this once-assertive ideology. Marxist view have exerted a stimulus on debates, but could not provide answers to the issues of this discipline. The hopes of development and prosperity a generation ago have evaporated only to be replaced by news of economic malaise, the food crisis, and crushing debt. In the late 1980's geographers addressed Third World environmental issues. Blaikie and Brookfield examined environmental deterioration among elements of the population-environment issue. Lewis and Berry dealt with African environments and resources. Watts and Bassett touched on agrarian and political concerns in West Africa. Adams examined water resources development in Nigeria's Sokoto Valley. Bryceson analyzed the political economy of agriculture in Tanzania. Lawson depicted how government policy bore on agriculture and its regional pattern. Crush detailed the absorption of Swazi labor into the South African economy. Dayal described the deficiency diet of agricultural workers in Bangladesh. Others examined Africa's financial disaster, Japan's trade surplus, and the global population crisis. Nevertheless, the dearth of output on and neglect of Third World issues by human geographers awaits positive research publications.     

Population studies

A number of studies have been published about the population change in New Zealand between 1936 and 1986. During this time an intellectual and demographic revolution also took place simultaneously. From 1961 and 1986 the population increased from 2.4 million to 3.3 million mainly because of Polynesian immigration, and the elderly and females also increased. The Maoris became urban. Mortality stayed stable, but fertility declined to below replacement level in the 1980's. Murray Wilson (1988) analyzed the relationship of fertility and mortality in terms of a post-transitional (developed) society like Australia or the European norm of a 2-children family. In his view the youth culture, television, and female aspirations greatly influenced childrearing. Daniel Noin (1988) examined the current state of geographical research on mortality from a methodological point of view finding wide differences in mortality in Quebec, Brussels, Paris, and London attributable to culture. Mosley and Chen (1984) argued that social, cultural, and economic factors to mortality are mediated by individual, household, and community variables. Jones and Moon (1987) dealt with medical geography in the context of the consumption of health care and disease ecology. Momsen and Townsend (1987) addressed the role of women in developing countries stating that gender is socially created and it examined the worldwide subordination of women. In the 1980's a host of other authors have also touched on the subject of the demography of gender analyzing discrimination against female children, unmarried American women, and single parent families. Yet Fahey (1988) stated that gender was only regarded relevant by Australian geographers as a demographic variable.     

Incorporating the effects of spatial structure in discrete choice models of migration

Discrete-choice theory and logit models are evaluated for their usefulness in analyzing migration patterns in a zonal system. The authors "argue that spatial effects and more specifically the relative location of zones are not taken into account in such analyses. We, therefore, introduce a measure of spatial structure and advocate its usage as a predictor of migration in such models. In an example of intrametropolitan migration in Toronto [Canada], we demonstrate that this variable is not only significant but also it improves the performance of all the other variables with the greatest impact on the distance between zones. In addition, inclusion of this variable improves the overall performance of the model in terms of residuals."
