Inter‐artifactual Technology Transfer: Road Building Technology in the Netherlands and the Competition Between Bricks,Macadam, Asphalt and Concrete

How did asphalt become dominant in pavement technology? This analysis argues that the victory of asphalt, as of many other technologies that compete with alternatives, is not so much the result of substitution at the level of the artifact or of the technology, but rather is the result of competition at the level of (technical) properties and (user) functions. The case of pavement technology shows that that technology becomes dominant which appears to be able to integrate as many functions as possible, and notably those originally provided by rival technologies, into its own system. This analysis concludes that in the history of technology the artifact does not always seem to be the most fruitful unit of analysis. Seen from the perspective of the user, artifacts are carriers of function sets. From the perspective of the designer or producer, the technology or artifact that contains the set of properties which best enables the preferred function set has a better chance of becoming dominant.     

The Primacy of Science in Modernity,of Technology in Postmodernity,and of Ideology in the History of Technology

The abrupt reversal of culturally ascribed primacy in the science–technology relationship—namely, from the primacy of science relative to technology prior to circa 1980, to the primacy of technology relative to science since about that date—is proposed as a demarcator of postmodernity from modernity: modernity is when ‘science’ could, and often did, denote technology too; postmodernity is when science is subsumed under technology. In support of that demarcation criterion, I evidence the breadth and strength of modernity’s presupposition of the primacy of science to and for technology by showing its preposterous hold upon social theorists—Marx, Veblen, Dewey—whose principles logically required the reverse, viz. the primacy of practice; upon 19th and 20th century engineers and industrialists, social actors whose practical interests likewise required the reverse; and upon the principal theorizers in the 1970s of the role of science in late 20th century technology and society. The reversal in primacy between science and technology ca 1980 came too unexpectedly, too quickly, and, above all, too unreflectively to have resulted from the weight of evidence or the force of logic. Rather, it was a concomitant of the onset of postmodernity. Oddly, historians of technology have remained almost wholly unacknowledging of postmodernity’s epochal elevation of the cultural standing of the subject of their studies, and, specifically, have ignored technology’s elevation relative to science. This I attribute to the ideological character of that discipline, and, specifically, to its strategy of ignoration of science.     

Archaeological and archaeomagnetic dating at a site from the ager Tarraconensis (Tarragona,Spain): El Vila-sec Roman pottery

A very accurate archaeological dating of a Roman site in NE Spain (El Vila-sec) was made based on the typology of pottery artifacts. Three different phases were identified with activity ranging from the mid-1st century BC to the early-3rd century AD. Analyses of bricks from kilns at El Vila-sec produced data on their stored archaeomagnetic vector. These data were compared with the secular variation curve for the Iberian Peninsula and the SCHA.DIF.3K regional archaeomagnetic model. Both, the reference curve and the model, produced probability distributions for the final period of use for two kilns from the second archaeological phase that were not used during the third phase. At a 95% confidence level, both time distributions cover a wide chronological range including the presumed archaeological age. Both the Iberian secular variation curve and the SCHA.DIF.3K regional model proved to be suitable models for dating the site, although on their own they do not produce a single unambiguous solution. This archaeomagnetic approach could also be applied to neighbouring archaeological sites that have an imprecise archaeological age.     

Testing the provenance of Patayan pottery at Las Colinas: chemical and petrographic analyses of phyllite-temper fragments

Mobile Patayan foragers of the interior desert of southwestern Arizona were makers of Lower Colorado Buff Ware ceramics. These containers were sometimes traded to Hohokam irrigation agriculturalists at the western margin of the Hohokam territory. By A.D. 1100, the distribution of Patayan Buff Wares shifted to the east, penetrating the Hohokam heartland. Some theorists have suggested the ceramic distribution implies a migration of Patayan people, who joined agricultural communities in the Hohokam core area. One way to assess this idea is to identify the production of Patayan material culture within the Hohokam territory. We test for the local manufacture of Lower Colorado Buff Ware at the Hohokam village of Las Colinas, where Patayan pottery was found in abundance, and a Patayan enclave has been inferred. Using petrographic analysis and SEM-EDS assays of the phyllite temper fragments in the Patayan wares, we conclude that the Patayan pottery was made elsewhere and was not fabricated with local materials at Las Colinas.     

The Lower Palaeolithic on the northern plateau of the Iberian Peninsula (Sierra de Atapuerca,Ambrona and La Maya I): a technological analysis of the cutting edge and weight of artefacts. Developing an hypothetical model

This article analyses the relationship between the weight and cutting edge of lithic artefacts from the main Lower Palaeolithic sites on the northern plateau (Meseta) of the Iberian Peninsula. The weight and cutting edge of a tool determine its cutting ability and the amount of force it is capable of, making them extremely important aspects of study to further our understanding of the potential capacity for human intervention in the environment. However, the analysis of these features has not received much attention in the ongoing debate on the Palaeolithic era in Europe. This study argues that the quantitative and qualitative technological analysis of these two aspects is of fundamental importance in determining the potential of lithic assemblages.     

The Use of Animal Hair in Ceramic Manufacturing at the Tytkesken-2 Neolithic Site,Western Siberia

The comb pottery found at Tytkesken-2 horizons 7, 6, 4A, and 4 reveals traces of animal hair. Hair was used as armature at the shaping stage: it was wound around the body of the vessel to prevent cracking during baking and drying (pastes were prepared without the use of hair). As the Tytkesken-2 ceramics demonstrate, using hair as armature was a local tradition, practiced in some measure from the Early to the Final Neolithic period.     

Detecting the effects of selection and stochastic forces in archaeological assemblages

Detecting and diagnosing the causes of change through time in archaeological assemblages is a core enterprise of archaeology. Evolutionary approaches to this problem typically cast the causes of culture change as being either stochastic in origin, or arising from selection. Stochastic sources of change include random innovations, copying errors, drift and founder effects among dispersing groups. Selection is driven by differences in payoffs between cultural variants. Most efforts to identify these evolutionary forces in the archaeological record have relied on assessing how well the predictions from a neutral-stochastic model of cultural transmission fit a data set. Selection is inferred when the neutral-stochastic model fits poorly. A problem with this approach is that it does not test directly for the presence selection. Moreover, it does not account for the fact that both neutral-stochastic and selective forces can act at the same time on the same cultural variants. A different approach based on the Price Equation allows for the simultaneous measurement of selective and stochastic forces. This paper extends use of the Price Equation to the analysis of selective and stochastic forces operating on multiple artifact types within an assemblage. Ceramic data presented by Steele et al. (2010, Vol. 37(6): 1348–1358) from the Late Bronze Age Hittite site of Bo?azköy-Hattusa, Turkey, provide an opportunity to evaluate the efficacy of this model. The results suggest that selection is a dominant process driving the frequency evolution of different bowl rim types within the assemblage and that stochastic forces played little or no role. It is also clear, however, that we should be attentive to combinations of direct and indirect selective effects within assemblages consisting of multiple artifact types.     

Analytical examination of animal remains from Borneo: the painting of bone and shell

Examination of a selection of shell and bone from archaeological assemblages excavated at Niah Cave and Gua Sireh, both of which are located in Sarawak, Borneo, has revealed the deliberate application of coloured material to one or more surfaces. Small fragments of the surface colourant were analysed using a variety of techniques, including microscopy, energy dispersive microwave analysis and infra-red spectrophotometry. These procedures established that, although red in colour, the applied coating in each instance was not red iron oxide. It is suggested that, based on the chemical components present, this coating was a tree resin or a similar organic substance. The paper further reports the presence of enhanced chloride values in the colourant recovered from the ancient human cranial fragment tested. It is suggested that elevated concentrations of this trace element may indicate that the site, the human remains or ingredients within the colourant were once in close proximity to the sea.     

Diversity in hunter–gatherer technological traditions: Mapping trajectories of cultural ‘descent with modification’ in northeast California

Recent work has demonstrated that technological traditions can be considered as systems of information transmission that operate on the principle of ‘descent with modification’. In this paper we present an ethno-historical case-study of northeast Californian hunter–fisher–gatherers. Our goal is to understand the factors generating long-term diversity in local material culture, and we begin by investigating the extent to which branching and reticulation explain variation in four distinct technological traditions – basketry, cradles, ceremonial dress and earth-lodges. We then examine whether these four traditions have been transmitted in tandem, or are characterized by entirely different descent histories. The results for this particular case-study suggest that the first three traditions have been closely associated during branching descent, while the earth-lodges appear to have entirely distinct transmission histories. The general analytical framework presented in this paper is readily exportable to other world regions, where local case-studies may generate contrasting insights into historically-contingent patterns of cultural inheritance. Further studies examining potential co-transmission of technological traditions are strongly encouraged as a welcome addition to the cultural transmission literature.     

Point/counter point: the accuracy and feasibility of digital image techniques in the analysis of ceramic thin sections

Digital Imaging Analysis has been proposed as an efficient alternative to traditional petrography for some applications. This paper tests that proposition in the measurement of temper size and abundance in four pottery thin sections from the Pevey Site, Mississippi. The findings of both studies are presented here and the relative merits of the two techniques are evaluated in terms of accuracy, precision, cost, and time.
