Patterns of exchange and the social production of pigs in highland new guinea: Their relevance to questions about the origins and evolution of agriculture

In recent years, cultural anthropologists have made notable progress in understanding the bewildering variety of material exchange transactions found among the aboriginal populations of highland New Guinea. One of the major findings of this work is that competitive exchange behavior may bring in its wake alterations in agronomic practices involving an intensification of production. That intensification is primarily a product of social behavior, rather than an adaptation to climate change or population pressure, is a significant conclusion that should influence the thinking of archaeologists as they investigate past episodes of agronomic change, including the origins of agriculture.     

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.     

Representing Structural Change in U.S. Migration Patterns

This paper focuses on the identification of three sets of relationships exhibited by a time series of age-specific national migration rates and multiregional transition probability matrices: the relationship across time for the same age group, as defined by period (temporal) transformation coefficients or matrices; the relationships across age at a particular moment in time, as defined by age transformation coefficients or matrices; and the relationships across time and age, as defined by cohort transformation coefficients or matrices. Given any two of these relationships one can solve for the third. This feature of age-period-cohort relationships has a practical application in the development of improved methods for representing structural change in migration patterns over time and for indirectly estimating migration patterns using inadequate data.     

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.     

CORN HYBRID SELECTION AND CLIMATIC VARIABILITY: GAMBLING WITH NATURE?

Farmer adaptation to climatic variability is explored via an analysis of corn hybrid selection in southern Ontario. Corn hybrid varieties are available for a wide range of conditions, including accumulated heat, measured as Corn Heat Units (chus). Hybrids with higher chu ratings generally have higher yields, so long as there is sufficient heat for them to mature. Farmers choose their hybrid varieties prior to the growing season, in the face of uncertainty about the chus that will accumulate at their location. Farmers in the sample counties showed a consistent tendency to adjust their hybrid selection on the basis of the previous year's growing conditions. After the high chu year of 1991, farmers chose significantly more longer-maturing and potentially higher-yielding, but riskier varieties. After the lower chu years of 1992 and 1993, farmers' hybrid selections became markedly more conservative. L'étude de I'adaptation des fermiers aux changements climatiques se fait par une analyse de /'hybridation du maïs au sud de l'Ontario. Les variétés de maïs hybrides conviennent à différentes conditions climatiques in-cluant la chaleur accumulée, mesurée en Unitées de Chaleur de Maïs (ucms). Les hybrides ayant une valeur ucm plus élevée donnent généralement un rendement plus élevéà condition qu'ils bénéficient d'assez de chaleur pour mûrir. Les fermiers des comtés sélectionnés ont démontré une tendance persistante à baser leurs sélections d'hybrides en fonction des conditions de crois-sance de I'année précédente. Depuis 1991, année ayant connu un taux élevé d'UCM, les fermiers ont opté pour un type d'hybride à croissance prolongée, au potentiel de rendement plus élevé mats également plus risqué. Les années 1992 et 1993 ayant connu un niveau ucm moins élevé, les fermiers ont alors sélectionné des hybrides plus traditionnels.     

Anthropology and Aboriginal Tradition: The Hindmarsh Island Bridge Affair and the Politics of Interpretation

Events that have become popularly known as ‘the Hindmarsh affair’ arose from conflict over a bridge development, and refer to an Aboriginal heritage issue that has had a significant impact on Australian society. 1 1 Justice Mathews (Commonwealth of Australia, 1996:1) begins her Commonwealth Hindmarsh Island Report with a similar assessment, noting how painful and divisive an affair it has been, and how enduring its legacies are likely to be.
The attendant controversy and dissension have ramified widely, beyond matters of Aboriginal heritage and its relationship to development, to include the status and role of anthropological research and reporting, past and present. A brief chronology of developments both prior to and following the Hindmarsh Island Bridge Royal Commission (1995) is provided here as a backdrop for discussion of these matters. Other salient issues also examined include: the nature of culture in relation to the complexities of ‘tradition’ and the effects of change; the structural correlates of secrets; the politics of interpretation; and the legitimacy of innovative processes in Aboriginal cultural construction and representation. In conclusion, some implications of the Hindmarsh affair for the anthropology profession are considered.
