Range of motion and energy cost of locomotion of the late medieval armoured fighter: A proof of concept of confronting the medieval technical literature with modern movement analysis

ABSTRACT

Study of technical, normative, and narrative medieval literature and of archaeological pieces allows the motor skills of armoured members of the aristocracy to be outlined but not quantified. The authors present novel data on the impact of wearing armour on both the freedom of movement and the energy cost of locomotion, and confront the results to systematic analysis of medieval written sources. An accurate harness replica realized in an informed archaeological experimental way, close to medieval material and manufacturing conditions, was used for the experiments. Measurements of the energy cost of locomotion in and out of armour were taken during walking and running on a treadmill. Gait analysis and range of motion of joints were performed with 3-D kinematics. The results indicated an increase in the energy cost of locomotion in slight excess to the added weight and for most movements studied reductions in the range of motion over the joint, potentially to the advantage of the wearer during combat. This proof of concept appears promising for further study in this field of scholarly endeavor.     

Comment by Jeffrey Herf

Abstract

Although fuel cells have been considered promising technology since the nineteenth century, fresh expectations – expressed by engineers, company leaders, politicians and journalists – began to flourish in the 1990s later on associated with the vision of a ‘hydrogen economy.’ Inspired by research in the history and sociology of expectations, the present paper analyzes this recent history of global fuel cells and hydrogen potentials as played out in the USA, EU, and especially Sweden. It is demonstrated that automotive shows, the mass media, and forecast projects were significant arenas in promoting and circulating the idea that fuel cells represented energy efficient and clean technology that almost by necessity would be utilized in the ‘vehicles of the future.’ This paper also highlights the framing of water both as a potential source of energy and as a symbolic purifying bath that would restore an environmentally friendly society, interpreted as an ecomodern utopia.     

Thermally Altered Novaculite and Stone Tool Manufacturing Techniques

Abstract

This paper describes a study of the physical origins of improved flaking properties, called flakeability, for novaculite, a material exploited for stone tool manufacture by the peoples of prehistoric Arkansas, Missouri, Texas, and Louisiana. Experimentation in thermal pretreatment and ways to detect and discriminate the results of this pretreatment were carried out. The criteria derived for distinguishing this alteration in the novaculite are easily determined by a straightforward analysis that can be done in almost any laboratory.

The results of this experimentation have direct implications for the study and identification of thermal pretreatment in this and other stone materials. From the correlations between the physical alteration of such source materials and the implication for manufacturing techniques, the archeologist can more validly infer relationships between prehistoric lithic technology and the knappers who developed highly diversified and specialized techniques. Such experiments combined with wear analysis, material source determination, and other lithic studies will allow the archeologist to delineate manufacturing and exploitative patterns and examine their relationship to all forms of cultural and environmental variables.     

The Automotive Industry Needs Research

Abstract

There is now an increasing need for research to meet the objectives of vehicle energy conservation and the case for this is presented here. It illustrates the need for basic research in areas such as heat transfer and combustion in alternative engines, instrumentation control, rheology and manufacturing processes for vehicle components and materials. Car manufacture needs research on thermomechanical treatments application of optimization theory, acoustic diagnostics and assembly of mechanical parts by robots. The best way of attracting the attention of the university community to such research are also discussed, emphasizing the role of establishing good communication channels.     

Chipped Stone Debitage,Material Selection,and Expedient Tool Production in Southeast Michigan

Abstract

This article summarizes the results of exploratory analyses on material sources and debitage attributes from chipped stone artifacts at sites identified and sampled by the Eastern Michigan University Field School along the Huron River Valley in southeast Michigan. Several hypotheses are tested with chipped stone debitage assemblages from 35 prehistoric sites to better understand material selection, expedient versus formal tool manufacturing, and the influence of material availability and mobility in chipped stone processing within the region. The distribution of debitage attributes (reduction stage, technology, condition, and size) are first compared by material source and quality. Then, the distributions of materials and debitage attributes are compared among small limited-use sites and two early Late Woodland small settlements. The results indicate a heavy reliance on poorer quality local cherts, and a focus on expedient tool manufacturing with both the local poorer quality and the nonlocal higher quality sources. There were no major differences in debitage assemblages between the limited use sites and the settlements.     

New World,New Politics,New Labour: Third Way Revisionism and Prophetic Political Theology

Abstract

Tony Blair's vision of a ‘third way’ political programme is formative of New Labour's second term revisionism, claiming to transcend traditional left-right distinctions and embody the principles of ‘equal worth’, ‘opportunity for all’, ‘responsibility’ and ‘community’. Drawing upon a variety of sources, Anthony Giddens among them, the following material sketches the lineaments of the ‘third way’ agenda Having identified its political aspirations and principal theoretical components, the article suggests a number of areas representing potentially fruitful points of contact for further theological reflection.     

The importance of materials R&D to the UK and the role of its National Physical Laboratory

Abstract

The importance of materials R&D to a modern economy, which arises because of the global competition between manufacturers and the essential maturity of all manufacturing industries, is illustrated with direct examples from the semiconductor industry. One result of this R&D is that the consumption of materials per capita decreases as the wealth per capita increases. The development of the materials work at the UK National Physical Laboratory since its foundation is then briefly reviewed, together with its development to meet modern demands. The resulting sophistication in the R&D demanded is illustrated and the link to computer assisted modelling, together with the necessity for extreme precision of input data, is emphasised. The type of materials work most intimately connected with maintenance of standards and metrology is then demonstrated.     

Form,function, fiction – translations of technology and design in product development

This article is a case study of the design and development of a Norwegian crockery series for institutional households – the 1962 Figgjo 3500 Hotel China. It investigates how this product represented a decisive break with the conventions of postwar Norwegian design and manufacture. The onset of international free trade meant export or die for the manufacturing industry. The elitist aestheticism so prevalent in the so‐called Scandinavian Design movement was abandoned in favour of an ideology remarkably akin to what was at the German Ulm School of Design called scientific operationalism. The paper also analyses how the manufacturer sought to portray this product: first, it was inscribed as science incarnated, and the material morality reigned supreme. But as society's faith in science took some serious blows in the course of the 1960s and modernist design idioms were partly forsaken in the 1970s, the engineered tableware became the fashioned tableware as trends tamed technology. These translations of technology, design, identity and consumption tell the story of how an artefact is constantly in a state of transformation – on both sides of the factory gate.     

Author response: between liberty and discipline

Abstract

Most accounts of the microelectronics revolution have emphasized the role of military patronage and procurement in the shaping of silicon technology and the consolidation of the semiconductor industry. Little attention has been devoted, however, to the silicon industry's shift from military to commercial markets in the early and mid‐1960s. Drawing on an examination of Fairchild Semiconductor, the firm that initiated this shift, this essay argues that the silicon industry's expansion into non‐military markets was indissociable from deep changes in manufacturing, organizational structures as well as component and system technologies. Special attention is devoted to the ways in which Fairchild created a user base for its products in the computer and consumer electronics industries by hiring engineers from these sectors and encouraging them to design components as well as applications for the firm's potential customers. This article also examines how Fairchild introduced mass production techniques from the automotive and electrical industries, delocalized its assembly operations to South‐East Asia, and developed new packaging techniques to meet the cost and manufacturing requirements of commercial users. This article is intended to contribute to recent interest in the role of user ‐ supplier relations in technological change and, more specifically, to the question of the pervasive use of silicon components across a wide range of industrial sectors, a central phenomenon in the history of industrialized economies since the 1960s.     

Our Heritage – Our Future

Abstract

Much of our present technology can be traced to the great discoveries at the beginning of our century, particularly relativity and quantum mechanics. This is our heritage. Based on these, reasonable extrapolations can be made for our future, and are here exemplified by microelectronics, lasers, molecular biology, new material, aviation and nuclear energy. But often the unexpected development is the most important, here compared with non-linear equations in mathematics. Man's great future will arise from such non-linearities and the space telescope may bring a new field theory, redundancy in computers may give us thinking machines and finally the discovery – or the proof of absence – of extra-terrestrial life will bring the greatest of all non-linear changes. It is concluded that human imagination is unlimited, that imagination lets man grow to transcend his limits and to fulfil his dreams.     

Burin Manufacture and Utilization: An Experimental Study

Abstract

Burins were experimentally manufactured and utilized to differentiate the effects on wear patterns of raw material, method of manufacture, material utilized, and mode of utilization. Differing methods of manufacture and modes of utilization were employed to test the assumed function of burins as being exclusively bone/antler working tools. Results of univariate and multivariate statistical tests are presented along with differentiating characteristics of three methods of manufacture (hard-hammer, soft-hammer, pressure), three types of raw materials (obsidian, basalt, chert), four materials worked (hard and soft wood; dry and soaked bone), and two modes of utilization (graving, scraping).     

Manufacturing mainframes: component fabrication and component procurement at IBM and Sperry Univac, 1960–1975

In the golden age of mainframes (1960–1975) one of the foremost issues facing mainframe computer firms was manufacturing – despite this fact, system design has received nearly all the attention of scholars to date. The greatest manufacturing concern of these mainframe producers was component technology: the selection and provision of memory, especially main memory. As this period progressed, semiconductor memory was coming to dominance. Increasingly, firms' performance in the expanding market for mainframes pivoted on their memory component decisions. International Business Machines (IBM) had become the dominant mainframe producer, and its particular response to the semiconductor memory challenge has taken the role as the default or natural position. A comparison of IBM's experience with that of their fiercest mainframe rival during this period, Sperry Univac, highlights the centrality of memory components to the overall mainframe business as well as the highly contingent and path‐dependent nature of the particular semiconductor policies and practices adopted by firms.     

Gramsci and the issue of religion: Catholic modernism and the Italian Partito Popolare

ABSTRACT

Gramsci's interest in Italian politics led him to tackle a key issue in the present-day discourse: the relationship between the Holy See and the national State. Additionally, he paid close attention to internal issues of Christianity, from its origins to his own times and – similar to many other socialist thinkers – he believed that there were several echoes between the early Christian experiences and contemporary socialism. From this arose his concern with the religious crisis of the early twentieth century – so-called ‘Modernism’ – as well as the story of the Partito Popolare (Popular Party, PPI), the organization founded by the priest Luigi Sturzo after the First World War, which was marked – especially amongst its left-wing components – by its anti-fascist positions.     

Structural concepts of anastylosis

Abstract

Ancient buildings have been re-erected for more than one hundred years, during which time various concepts concerning the preservation of monuments have been developed. Classical buildings in particular – considered to represent the European cultural heritage – became the focus of fundamental discussions. In order to understand and compare approaches to historic monuments, this paper contrasts ancient and modern building structures. New supporting systems – using modern substitute materials and connecting elements – nevertheless remain weaker than the original structures. From the beginning of the twentieth century until recent years, the concepts of anastylosis have in many cases been determined by what was technologically feasible at the time.     

The reburial of mosaics: an overview of materials and practice

Abstract

A significant proportion of the literature on the reburial of archaeological sites concerns mosaics. These publications reveal that a variety of materials have been used for mosaic reburial, including specialized fill and separation layers, from the early 1980s onwards. Although reburial practice often demonstrates an ad hoc and indiscriminate use of fill and separation materials, or the following of trends and anecdotal information favouring certain materials, knowledge of their characteristics is very important in developing an appropriate technical design for reburial of mosaics. The materials most commonly employed in mosaic reburial practice, including geotextiles, are reviewed and an assessment of their positive and negative characteristics within a reburial design is provided. Recent but limited laboratory and field testing, monitoring and evaluation of reburial interventions have begun to provide preliminary evidence about the behaviour of these materials, indicating which ones are most appropriate and how they should be utilized to best advantage. However, their selection and use remains uneven, and positive results continue to be as much a function of adequate maintenance as proper design and execution.     

Europe,public opinion,and Brexit*

ABSTRACT

The construction – and deconstruction – of Europe is a spatial democratic process, and public opinion is central to it. One part of public opinion is fuelled by pragmatic – either economic (the search for prosperity) or strategic (the need for security) – arguments. Another is fired by political, moral and religious ideologies and identities (and utopian views of Europe in particular). Attitudes concerning Europe were never identical in the Western or Eastern halves of the continent, or in Britain. They evolved in connection with processes of economic change (from the second to the third phase of the Industrial Revolution), and latterly in relation to globalization and its geographic impact. Euroscepticism demands a deep adjustment of Europe to its current political-intellectual scene and geographic organization.     

Early Animal Management Strategies during the Neolithic of the Konya Plain,Central Anatolia: Integrating Micromorphological and Microfossil Evidence

ABSTRACT

This paper examines the contribution of microscopic multi-proxy approaches to the study of early husbandry practices and animal diet by integrated micromorphological, phytolith, and calcitic dung spherulite analyses of midden deposits at the three neighbouring Neolithic sites of Boncuklu (9th–8th millennium cal BC), P?narba?? (7th millennium cal BC) and Çatalhöyük (8th–6th millennium cal BC) in the Konya Plain, Central Turkey.

The results reveal considerable chronological and contextual variation in human-animal inter-relations in open areas between different communities and sites. At Boncuklu, middens display well-defined areas where phytoliths and substantial accumulations of omnivore faecal matter low in spherulite content have been identified. By contrast, open spaces at the Late Neolithic campsite of P?narba?? comprise large concentrations of herbivore dung material associated with neonatal ovicaprine remains from spring birthing. Here, the deposits represent repeated dung-burning events, and include high concentrations of dung spherulites and phytoliths from wild grasses, and leaves and culms of reeds that, we suggest here, derive from fodder and fuel sources. Late middens at Çatalhöyük are characterised by thick sequences derived from multiple fuel burning events and rich in ashes, charred plants, articulated phytoliths – mainly from the husk of cereals, as well as the leaves and stems of reeds and sedges – and omnivore/ruminant coprolites, the abundance of the latter declining markedly in the latest levels of occupation.

The application of this integrated microscopic approach to open areas has contributed to unravelling the complexity of formation processes at these sites, providing new insights into herding practices, diet, and the ecological diversity of Neolithic communities in Central Anatolia.     

The Changing Cycle of Engineering Materials A Tribute to H. M. Finniston,Materials Scientist and Engineer

Abstract

In this, the second Finniston Lecture, the growth in the production, usage and disposal of engineering materials is reviewed on a worldwide scale over the period of Sir Monty's lifetime. He worked in all stages of the cycle. The materials treated are steel and the common non-ferrous metals, the bulk plastics (polyethylene, polypropylene, polyvinylchloride, polystyrene) and Portland cement. The total tonnage used is determined by improvement in quality, both in production and in service, the market demands, substitution by other materials and waste minimisation. These are considered for each material so as to show an emerging future in which demand per caput decreases as living standards rise. This fact, coupled with a philosophy of 'do more with less' and the pressures of environmental concerns are leading to an important change of emphasis within the materials cycle occasioned by the demand to increase the recyclability not only of the materials but also of the components made from them.     

Introduction: writing the contemporary history of European solidarity

Abstract

This introduction outlines the possibilities and perspectives of a history of ‘European solidarity’. While – given the high frequency with which the term is used in contemporary political debate – this is most certainly a hot-button issue, the topic has long been neglected by researchers on the history of European integration and European ideas. The reasons for this lack of empirical studies lie in the vagueness and the normativity of the term. This introduction thus conceptualizes ‘European solidarity’ as an analytical tool for research and discusses three major approaches to its historicization: first, deconstructing ideas and discursive notions of ‘European solidarity’, a term that has been omnipresent in primary sources in the nineteenth and twentieth centuries; second, investigating concrete practices of ‘European solidarity’, for example in welfare-state policies or in the work of civil-society actors; third, looking at historical limits of ‘European solidarity’ which help to bring contesting perceptions and motives into view. Finally, the introduction addresses the question of the analytical benefits of a history of ‘European solidarity’: it points among other things to new periodizations that help to avoid a teleological orientation in European historiography, as well as to the detachment of the European integration process from the institutionalization of the European Communities.
