Nestorian Crosses from Jabal Berri

Two small crosses, one of bronze and the other of mother-of-pearl, from the surface of a site near Jabal Berri in northeastern Saudi Arabia are presented. They are attributed to the Nestorian community of Bet Qatraye which is known from literary sources to have flourished during the Sasanian period.     

Pretransition marital fertility variation over time: was there deliberate control in England?

An important line of research concerning historical fertility patterns in currently developed countries of Europe has concluded that, prior to the fertility transition, marital fertility was essentially constant over time, and deliberate fertility control was virtually unknown. It has been argued that variations over time in overall fertility were largely the consequence of variations in nuptiality. Other researchers have challenged these views and present evidence for the existence of a significant minority of fertility controllers in pretransition populations. In this article, we find support for this second view and argue that (1) there was significant, non-random variation in marital fertility over time, prior to the transition; (2) in many cases, this variation in marital fertility was large relative to contemporaneous variations in nuptiality; and (3) in a substantial minority of the cases, the variation over time in pretransition marital fertility was so large that it is suggestive of deliberate fertility control. Thus, our findings question the view of fertility transition as an innovation in deliberate marital fertility control. While most of our evidence is based on data from England and Wales, we find corroboration of our key results in other European data.     

THE POSSIBLE FRACTIONATION OF LEAD ISOTOPES IN ANCIENT METALLURGICAL PROCESSES

The possibility of lead isotope fractionation in ancient lead production is examined. Kinetic theory relating to isotopic fractionation in non-equilibrium evaporation is considered and the feasibility of the alteration of lead isotope abundance ratios in ore roasting and smelting is assessed. Previous experimental work is shown to have been inconclusive and conclusions are drawn on the need for further research to quantify the possible extent of fractionation in practice.     

RADIOCARBON DATES FOR BEESWAX FIGURES IN THE PREHISTORIC ROCK ART OF NORTHERN AUSTRALIA

Accelerator mass spectrometry radiocarbon ages have been taken for a test suite of small samples of material removed from some of the ‘beeswax’art figures found in rock shelters in northern Australia. The results indicate that we can reliably date this unique form of rock art with no noticeable damage. We had not expected to find figures of any great antiquity, and so we were surprised to find that the ages obtained spanned the time period from the recent past to about 4000 BP.     

THE EFFECTS OF TAXES,EXPENDITURES, AND PUBLIC INFRASTRUCTURE ON METROPOLITAN AREA EMPLOYMENT*

ABSTRACT. Data for 28 metropolitan areas over a 15-year period are used to determine the impacts of government spending, taxes, and public infrastructure on total employment and disaggregated employment. After carefully controlling for the government budget constraint we find that taxes are negatively related to total employment and education spending is positively related to total employment. Nevertheless, we find that it is difficult for metropolitan areas to influence the composition of their employment with government tax and expenditure policies. Moreover, at current levels of public infrastructure, marginal changes in infrastructure have no strong effect on employment.     

THE ONTARIO COUNTRY ROAD AS A CULTURAL RESOURCE

This paper demonstrates that the morphology of ordinary rural roads tells much about regional development. It uses southern Ontario as a case study, but the principles may be applied widely. It is a plea for recognition of a deep heritage in unspectacular things: ditches, fence-lines, culverts, jogs in the survey, and more. This paper also encourages local and regional planners to conserve signs of change in the roadscape and to celebrate them. Roadside evolution is worth publicizing, and unnecessary destruction of elements that enhance the story must be discouraged.
Cet essai démontre que la morphologie des routes rurales ordinaires en dit beaucoup au sujet du développement regional. On peut employer cet exemple de /'Ontario du sud mais les principes peuvent s'appliquer d'une manière plus large. Dans ce manuscrit on doit reconnaître /'heritage profond des elements communs: des caniveaux, des clotures, des aqueducs, des irrégularity de I'arpentage, etc. Cet essai encourage aussi les planificateurs i conserver ces signes du paysage routier et à les mettre en Évidence. On doit les faire connaître au public, et décourager leur déstruction.
