Connecting meanings of ageing,consumption, and information and communication technologies through practice

Practices involving the consumption of Information and Communication Technology (ICT) are increasingly important to the maintenance of everyday life for older New Zealanders. Developing competency with ICT can provide a way of challenging negative discourses of ageing. Interviews with 20 older New Zealanders reveal that “keeping up” with the times, with changing technologies, and with others is a means by which to shape aged subjectivities. However, while competency in ICT practices enables participants to refute discourses of ageing that locate older people negatively as part of an aged digital divide, it can also work to reproduce this divide. Consequently, understanding the nuanced and situated nature of meanings related to ICT practice is necessary in order to interrogate normative assumptions associated with the “more than human” possibilities of ageing well.

Dietary adaptation during the Longshan period in China: stable isotope analyses at Liangchengzhen (southeastern Shandong)

Rice and millet were staple crops at Liangchengzhen, a late Neolithic Longshan site in Shandong, China, but the degree of dietary variation is not known. This study uses stable isotope analysis of human and faunal skeletal remains to quantitatively address the importance of these crops as well as terrestrial domesticates and aquatic resources in the diet at Liangchengzhen. Although no collagen could be extracted from the poorly preserved human bones, the δ¹³C stable isotope results for 2 apatite sample and 16 tooth enamel samples averaged −9.8‰ suggesting that diet was based on foods averaging from −24‰ to −18‰, with millet and millet-fed animals comprising at most approximately 25–30% of the diet. Pig faunal δ¹³C isotope values suggested that during the earlier Longshan period pigs were fed mainly millet with more C₃ foods such as rice included by the later Longshan period. Solid ceramic residues from two guan jar sherds produced δ¹³C values averaging −18‰ and δ¹⁵N values averaging +16‰, suggesting both vessels contained fish. The results of the study indicate that by the Longshan period, people in southeastern Shandong no longer relied as heavily on millet and that the agricultural crop of rice had increased in importance at Liangchengzhen. Unfortunately, without human collagen samples to provide nitrogen isotope results, we cannot estimate the relative contribution of aquatic and terrestrial protein to the diet of people at Liangchengzhen. In general, however, the pattern of a diverse agricultural system on the basis of the macrobotanical remains from Liangchengzhen is supported by the isotopic results.     

Chemical evidence for wine production around 4000 BCE in the Late Chalcolithic Near Eastern highlands

Archaeological excavations in the Areni-1 cave complex in southeastern Armenia revealed installations and artifacts dating to around 4000 cal. BCE that are strongly indicative of wine production. Chemical evidence for this hypothesis is presented here using a new method to detect the anthocyanin malvidin that gives grapes and pomegranates their red color. Using solid phase extraction (SPE) and alkaline treatment of the samples, followed by combined liquid chromatography-tandem mass spectrometry (LC-MS/MS), this method was applied to authentic standards and four ancient potsherds from Armenia and Syria. A positive result was observed for two of the samples from the Areni-1 cave complex, adding evidence supporting the hypothesis that wine was produced in the Near Eastern highlands in the Late Chalcolithic Period.     

A proxy of potters’ throwing skill: ceramic vessels considered in terms of mechanical stress

This study is aimed at evaluating potters’ skills according to the mechanical characteristics of the vessels they produced. It focuses on wheel thrown vessels. In a first stage, considering that the difficulty of throwing ceramic vessels is to a significant extent determined by the risk of collapse of the thrown structure, we applied the method of finite element modelling to derive an index of mechanical stresses operating within a vessel. Validated via compression tests, the so-called Von Mises stress index was employed as a global index of mechanical difficulty. Because this index allows comparisons between vessels of different form, mass, and clay properties, it provides a more powerful tool than existing techno-morphological taxonomies. In a second stage, in order to relate the Von Mises stress index to throwing difficulty, we analysed the geometrical and mechanical characteristics of vessels thrown by eleven expert potters invited to reproduce four different model forms with two different masses of clay. The results demonstrated that reproductions revealed subtle but systematic deviations from the model forms that allowed a decrease in the mechanical difficulty. More difficult forms showed larger degrees of mechanical optimisation. These results, in combination with a new analysis of data from Roux’s (1990) study with potters of different skill levels, indicate that skill resides, at least to a certain extent, in the capacity to marshal the operative mechanical constraints. In other words, the latter, measured by the Von Mises index, provides a useful signature of a potter’s skills.     

Notes on Contributors

The purpose of this paper is twofold. It aims first to provide a critical overview of the literature on the history of technology as it relates to colonialism, decolonization and development in the extra‐European world during the 20th century. Second, it seeks to identify changing perspectives and emerging research issues in the history of technology in the European colonies and ex‐colonies of Asia and Africa, and thus to trace a move away from earlier ‘diffusionist’ arguments and discussion of polarization and conflict between ‘Western’ and ‘indigenous’ technologies, toward a more interactive, culturally‐nuanced, multi‐sited debate about how technology functions within specific parameters of time, place and culture. Body, land and state are identified as major ‘triangulation’ points for the critical investigation and contextualization of these issues.     

A baffling experience: Technology transfer,Anglo-American nuclear relations,and the development of the gas centrifuge 1964-70*

The development of the gas centrifuge in the 1960s revolutionized the production of enriched uranium. More simple and efficient than gaseous diffusion, the centrifuge offered countries a means of producing enriched uranium independently of America. For Britain, the centrifuge possessed political as well as economic advantage. It provided the opportunity for Britain to share nuclear knowledge with its European partners, so improving the prospect of successful admission to the European Common Market. In Washington, the prospect of a joint European centrifuge project received an ambivalent response. The State Department, keen to foster a strong Europe as a bulwark against Soviet expansionism, welcomed collaboration. In contrast, the Atomic Energy Commission, charged with maintaining US nuclear security, sought to block the venture on the grounds that it infringed US law. This paper reviews this debate, examining Anglo-American nuclear relations in the context of Britain's entry into the European Common Market. It argues that Britain was determined to establish a purely European solution to the question of uranium supply even if this led to a breach in Anglo-American relations.     

Depth records and ocean volumes: Ocean profiling by sounding technology, 1850-1930

Oceanographic research commencing in the mid-19th century could not rely on the direct observation of its object, but had to create its images of ocean depth through remote investigation. Depth became a matter of scientific definitions, systematic measurements, and graphic representations. In the course of a century, the opaque ocean of the 1850s was densely depicted in physical terms and transformed into a technically and scientifically sound oceanic volume. Tracing the history of deep-sea sounding technology from wire sounding around 1850 to acoustic sounding in the early 1920s, the paper investigates the relation and interplay between conceptual, pictorial, and technological depth performance. Addressing the conditions and limitations oceanographers encountered in producing single measurements and arranging them into profiles and contour line charts, the paper takes on a narrative approach to spatial representation: resembling a narrated or written story, the texture of depth depended on the richness and coherence of its plots.     

Under construction: material integration of the Netherlands 1800–2000

This article investigates the material integration in the Netherlands. Section 1 maps the proliferation of network technologies during the last two centuries. Sections 2 and 3 scrutinize the complex dynamics of network development for selected cases. The case of the electricity supply network reveals how institutional frameworks stabilized network development despite conflicts and contingencies, and how competing (gas supply) networks affected network development. The cases of the Rotterdam harbour, Amsterdam Airport Schiphol and the city address innovation and professonalization processes at the level of network nodes, which tie different networks together and heavily affect overall network morphologies and flows. Section 4 addresses the ‘vulnerability paradox’ as a specific characteristic of the networked nation.     

What happened to provocation in science and technology studies?

Science and technology studies (STS) is an important and often controversial interdisciplinary field which has proved to be provocative and influential. But has its institutionalization and influence occurred at the expense of some of its provocative power? This paper considers the fate of provocative ideas associated with STS as they become appropriated and transformed by new social institutions and audiences. It aims to sketch a preliminary framework for analysing the social dynamics of the persistence and/or attenuation of its ideas and impacts. The argument reviews the main early aspirations and targets of STS. It suggests that changing emphases in STS can be understood as responses to successive versions of the principle of symmetry. It argues that the continual renewal and recruitment of audiences for STS is central to sustaining its capacity for provocation.
