WORKER DISPLACEMENT AND JOB-SEARCH: A REGIONAL ANALYSIS OF STRUCTURAL IMPEDIMENTS TO REEMPLOYMENT*

ABSTRACT. This study investigates the human, and in turn the regional, consequences of industrial restructuring in the United States. Our methodology presumes that labor market outcomes of displaced workers can provide considerable information on the structural properties of local labor markets, and subsequently upon the capacity of such areas/regions to reemploy additional workers. The examination follows two steps. In the first, a multivariate model of reemployment likelihood is developed and subsequently estimated. Separate equations are obtained for various resons of the country, a disaggregation that permits one to identify how postdisplacement reemployment, and its determinants, vary systematically across space. In the second step, the above estimates are decomposed into two elements, one of which is reflective of regional structural conditions. Based upon this methodology and estimates obtained in the first step, regions of the country are compared as to magnitude of their structural economic problems, and thus as to their capacity to gainfully reemploy additional workers displaced by plant closure or relocation.     

Simplexity and the Reinvention of Equifinality

Some earth surface systems apparently exhibit deterministic chaos, where small differences in initial conditions produce increasingly divergent results. This casts doubt on the venerable concept of equifinality, whereby surface features converge to similar forms. However, chaotic systems exhibit a broader-scale order, and their complex patterns occur within well-defined limits. This broad-scale order arising from smaller-scale chaos produces simplexity, where simple rules and regularities emerge from underlying complexity, when the broad-scale structures are independent of the fine-scale details. Chaos precludes equifinality, sensu stricto, at certain scales, but simplexity produces equifinality at others. Simplexity is illustrated in a case study of soil-landform relationships.

An approach to mapping buried prehistoric palaeosols of the Atlantic seaboard in Northwest Europe using GPR, geoarchaeology and GIS and the implications for heritage management

Widespread layers of well-preserved organically and archaeologically rich palaeosols dating to the Bronze Age and Iron Age are known from across the Atlantic seaboard of Scotland, including the Western Isles, Orkney and Shetland. The survival of these soils has been facilitated by an overburden of Aeolian sand forming dunes above them. Whilst these soils display archaeological importance, they are constantly under threat from erosion through storm damage due to their exposed coastal position. This presents certain challenges with regard to heritage management, since their extents are largely unknown, normally only being identified when exposed by wind and storm erosion. Consequently, following such damage mitigation can only be reactionary in response to archaeological deposits being uncovered, and left open to threat, Without accurately mapping the extent of these important deposits, archaeological landscape management is compromised.This paper presents a case study aimed at enabling proactive management of these deposits through rapid three-dimensional mapping undertaken using a combination of borehole-calibrated GPR survey and GIS modelling. The results demonstrate how effective baseline data can be generated to highlight areas of greater or lesser risk thereby providing the potential for quantifying and predicting the effects of damage from future storm events.     

Stable isotopic evidence for diet in a Roman and Late Roman population from Leptiminus,Tunisia

This study investigates the diet of the Roman and Late Roman population of Leptiminus on the Mediterranean coast of Tunisia. Stable carbon and nitrogen isotope analysis of human bone collagen and carbonate samples obtained from individuals buried in four cemeteries at Leptiminus was conducted in order to reconstruct the diet of the population, investigate the relative importance of marine vs. terrestrial resources, explore sex-, age-, and status-based variations in diet, examine temporal changes in the types of foods consumed, and compare the diet at Leptiminus with that of other Roman populations. The results of this study indicate that the residents of Leptiminus consumed a diet that was heavily reliant on terrestrial plant resources with the addition of a significant amount of marine resources. There were no significant sex differences in isotope values. In contrast, distinct dietary differences were seen between the adults and children. Nitrogen isotope values suggest that weaning began before the age of two and was completed by about 3 years of age, a finding consistent with previous isotopic studies of Roman samples. A temporal shift in diet is suggested by the nitrogen isotope values measured in samples from the most recent cemetery. A comparison of the data from Leptiminus with that derived from other Roman sites indicates that regional variability in diet existed within the Empire.
