Conceptualizing and Researching Policy Convergence1

This article develops criteria to classify the relative development of public policies across countries as convergent, divergent, identical and synchronous, and indeterminate. It emphasizes that relative policy developments have to be compared over defined time periods, and that they cannot be aggregated or averaged over several time periods, or across policy sectors or policy dimensions. The significance of policy convergence between countries needs to be evaluated against relative policy developments between other countries during the same period. Given these rigorous conceptual and methodological requirements, it is doubtful whether policy convergence is as pervasive as generally assumed in the literature.     

THE LONG-RUN ECONOMIC IMPACTS OF FEDERAL,STATE, AND LOCAL FISCAL POLICIES IN METROPOLITAN AREAS*

ABSTRACT. This paper uses new estimates of metropolitan factor demand and output supply functions to study how federal, state, and local fiscal policies affect metropolitan economies. We illustrate our work with findings for ten metropolitan areas in five states for changes in state corporate income taxes, local property taxes, the federal corporate income tax, an investment tax credit, interest rates, public capital stocks, output prices, and tax and regulatory policies affecting gross wages. It is clear from these simulations that a policy that is nominally the same everywhere will have repercussions that vary widely across regions and cities.     

AN ASSESSMENT OF BACK-SCATTERED ELECTRON PETROGRAPHY AS A METHOD FOR DISTINGUISHING MEDITERRANEAN OBSIDIANS

The recent application by Burton and Krinsley (1987) of back-scattered electron (BSE) petrography to obsidians from sources located in the south-western United States established that this method can effectively resolve and characterize included micro-crystalline phases that have proven difficult to analyse by optical thin-section microscopy. In the first extension of their original study, we have examined, using BSE petrography, obsidians from island sources located in the Mediterranean, including sources known to have been exploited in prehistory. Because of the kinetic contrasts on their crystallization, these microcrystalline phases reflect the magmatic history of the obsidian, providing information about superheating, supercooling, sub-solidus processes, and other phenomena. This information is of significance for the chemical analysis of Mediterranean obsidians and also as the basis for a powerful alternative to existing non-destructive analytical methods for the sourcing of archaeological and art-historical obsidian.     

MULTICOIN: A TOOL FOR CLASSIFYING COINS IN A MULTIMEDIA ENVIRONMENT

Classifying coins found during excavation is a challenging task for the archaeologist. This paper describes a multimedia system designed to assist the archaeologist by enabling him either to classify coins based on a pre-existing catalogue or to draw up his own catalogue for specific purposes. The system can also be used to train novices in the field: following an initial screening, the archaeologist only has to examine coins specifically requiring his expertise. A case study uses coins minted in Salerno 800–1200 AD, but the system has been designed to classify any set of coins by simply changing the underlying knowledge base. Very little training is required to operate the user-friendly system, which runs on multimedia PCs, as it is written using the C++ language and makes full use of the advanced features of Windows 3.11.     

Ancestral pueblo population aggregation and abandonment in the North American Southwest

After over a century of archaeological research in the American Southwest, questions focusing on population aggregation and abandonment continue to preoccupy much of Pueblo archaeology. This article presents a historical overview of the present range of explanatory approaches to these two processes, with a primary focus on population aggregation in those regions occupied by historic and prehistoric Pueblo peoples. We stress the necessarily complementary nature of most of these explanations of residential abandonment and aggregation. Case studies from the northern Southwest illustrate the continuous nature of these processes across time and space. We suggest that additional explanatory potential will be gained by the use of well-defined theoretical units to frame our current approaches. We extend the use of the local community concept as a theoretical unit of organization that, along with explicit archaeological correlates, should help advance our research into population aggregation and abandonment in this and other regions of the world.     

Technology transfer agencies and regional economic development

Many regions in Western Europe have set up technology transfer agencies in order to support endogenous potential by encouraging the diffusion of new technologies from universities and large firms to small and medium‐sized enterprises (SMEs). However, many studies have shown that business partners such as customers and suppliers are the most important partners for the stimulation of the innovativeness of SMEs. Universities and transfer agencies are given a very low rank in these studies. These results have led to doubts about the usefulness of these institutions for regional economic development. In order to increase transparency, streamlining of the agencies involved is necessary so that there are fewer actors and more cooperation between them. To be able to reach technology‐following SMEs, at least one transfer organization in every region should employ senior engineers with extensive business experience to visit firms frequently (proactive) to help them come up with some technological issues (demand‐oriented). These agencies need long‐term financial backing so as to provide free advice to technology‐following SMEs.     

Walter Benjamin: Quel matérialisme? Quelle histoire?

Cet article est consacré à l'étude de quelques uns des aspects de la philosophie de l'histoire de Walter Benjamin qui, aujourd'hui, suscitent le plus d'intérêt. En pratique, il analyse la notion de progrès, le rôle joué par l'écoulement du temps et l'interruption messianique. Il insiste aussi sur la critique du marxisme vulgaire entreprise par W. Benjamin et met en évidence ses apports les plus personnels ; enfin, il attire l'attention sur le risque encouru par les historiens qui orientent leur travail vers le futur et se montrent aveugles en ce qui concerne le passé.
