Abtract:Practitioners of archaeological and historical metallurgy have begun to identify their discipline by a new term: “archaeometallurgy.” Tracing the roots of this discipline shows that up to about 1980 the focus of study was on the technical examination of metal objects and determining site plans of metallurgical installations. Essentially it was a study of ancient metals of interest to historians of art or of technology. The focus then shifted to other materials and their archaeological contexts, processing byproducts such as slag, matte, furnace linings and furnace bottoms, crucibles, molds, cupels and tuyeres which are often more abundant on sites than metal. Thus the field of study has been enlarged beyond metallurgy to an interdisciplinary undertaking of materials science, archaeology, and material culture. Simultaneously with this shift in focus came the application of newly-developed instrumentation which supported a parallel shift in methodology from one emphasizing chemical analysis and microstructure to one of materials charactexrization, emphasising properties and performance.

ABSTRACTFor the last several years, we have been developing and characterizing “mobile” micro- and nano-instruments for use on-site (e.g., in the field). Although such portable, battery-operated instruments are much smaller that their laboratory-scale counterparts, sometimes they provide comparable performance and they often offer improved capabilities. As such, they are expected to cause a paradigm shift in classical chemical analysis by allowing practioners to “bring the lab (or part of it) to the sample”. Two classes of examples will be used as the means with which to illustrate the power of micro- and nano-instruments. One class involves a “patient” as the sample and an ingestible capsule-size spectrometer used for cancer diagnosis of the gastro intestinal tack as (part of) “the lab”. The other involves the “environment” as the sample and a portable, battery-operated, miniaturized instrument that utilizes a PalmPilot™ with a wireless interface for data acquisition and signal processing as (part of) “the lab”. To discuss how to electrically power such miniaturized instruments, mobile energy issues will be addressed. Particular emphasis will be paid to current or anticipated future applications and to the paradigm shifts that may prove essential in powering the next generation of miniaturized instruments.

ABSTRACTA comparative study investigating the integration of supplemental teaching resources in materials science education was developed for the purpose of determining the effectiveness of teaching strategies. Digital stories created by students, excerpts from the Nova Making Stuff documentaries, YouTube educational videos and student generated demo-kits were used as part of the investigation whereby two 9th grade science classes (n~26) were evaluated. Each participant in the study received one period (40-min) of a traditional lesson on Materials Science including specific content, vocabulary, and a pre- and post- lesson assessment. Additionally, the students in each class participated in a 30-min supplemental component, e.g. video or activity-based demonstration using aforementioned kits or video compilation. Pre- and post- evaluations (e.g. open-ended and likert questions) were administered to all of the participants. As hypothesized, the students’ feedback and performance on assessment activities reveal that the use of multimedia and activity-based resources may be equally effective teaching methods as traditional methods.

Decision making in health care has become increasingly reliant on information technology, evidence-based processes, and performance measurement. It is therefore a time at which it is of critical importance to make data and analyses more relevant to decision makers. Those who support Bayesian approaches contend that their analyses provide more relevant information for decision making than do classical or “frequentist” methods, and that a paradigm shift to the former is long overdue. While formal Bayesian analyses may eventually play an important role in decision making, there are several obstacles to overcome if these methods are to gain acceptance in an environment dominated by frequentist approaches. Supporters of Bayesian statistics must find more accommodating approaches to making their case, especially in finding ways to make these methods more transparent and accessible. Moreover, they must better understand the decision-making environment they hope to influence. This paper discusses these issues and provides some suggestions for overcoming some of these barriers to greater acceptance.

AbstractSome forms of renewable energy have long contributed to electricity generation, whereas others are just emerging. For example, large-scale hydropower is a mature technology generating about 16% of global electricity, and many smaller scale systems are also being installed worldwide. Future opportunities to improve the technology are limited but include upgrading of existing plants to gain greater performance efficiencies and reduced maintenance. Geothermal energy, widely used for power generation and direct heat applications, is also mature, but new technologies could improve plant designs, extend their lifetimes, and improve reliability. By contrast, ocean energy is an emerging renewable energy technology. Design, development, and testing of a myriad of devices remain mainly in the research and development stage, with many opportunities for materials science to improve design and performance, reduce costly maintenance procedures, and extend plant operating lifetimes under the harsh marine environment.

This article explores the relationship between the making of things and the making of people at the Bronze Age tell at Százhalombatta, Hungary. Focusing on potters and potting, we explore how the performance of non-discursive knowledge was critical to the construction of social categories. Potters literally came into being as potters through repeated bodily enactment of potting skills. Potters also gained their identity in the social sphere through the connection between their potting performance and their audience. We trace degrees of skill in the ceramic record to reveal the material articulation of non-discursive knowledge and consider the ramifications of the differential acquisition of non-discursive knowledge for the expression of different kinds of potter's identities. The creation of potters as a social category was essential to the ongoing creation of specific forms of material culture. We examine the implications of altered potters' performances and the role of non-discursive knowledge in the construction of social models of the Bronze Age.

Best value PIPS has been introduced in the Netherlands in the procurement of construction systems. The Water Board De Dommel utilized best value PIPS to select engineering consultant services. The test differed from other Dutch tests in that the PIPS process used the pre-award phase before the award phase. The best value selection of engineers also proposes that design firms can compete on value (price and performance). The engineering selection process was much closer to the original BVP/PIPS than the construction phases. The major lesson learned is the BVP/PIPS is a paradigm shift. The success of the test led to the recommendation of more professional services using BVP/PIPS.

From Neolithic Malta, there is evidence of increasing population size accompanied by increasingly elaborate material culture, including the famous megalithic architecture. Stoddart et al. (1993) argued that social tensions and controls increased as food resources diminished. One important requirement of this argument is that the Neolithic inhabitants of Malta depended entirely on domesticated plants and animals for subsistence and therefore, with increased population sizes, the poor agricultural potential of these islands was stretched. However, it is possible that the consumption of wild foods, particularly marine resources, in the Neolithic would make up any shortfall in the agricultural foods. A direct way of measuring the amounts of marine protein in human diets is through chemical analysis of human bone. Stable isotope analyses undertaken on seven Accelerator Mass Spectrometer (AMS) radiocarbon dated humans from the Neolithic at the Brochtorff Circle indicated that there is no evidence for the significant use of marine foods by these Neolithic individuals. These new data indicate that agricultural foods were the dietary staple for this sample of the Maltese Neolithic population and therefore support the argument that increasing population during the Neolithic could have resulted in increasing resource stress.

Beginning with two vivid examples that illustrate the Handbook’s core arguments—that politics is performative, performance is political, and that both of these matter to understanding our worlds—the introduction provides a current, contextual account of the shared syntax of politics and performance. It defines key terms, such as politics, performance, theatricality, and performativity, that inform the Handbook contributions. Through accessible and provocative engagements with new ways of thinking about politics and performance in both disciplinary and interdisciplinary modes, the introduction shows that these categories are interwoven and entangled in complex and consequential ways. It outlines the states of the art in theater and performance studies and politics, respectively, capturing key points of interconnection between these discourses in order to build on, extend, and reshape interdisciplinary conversations. Finally, it reflects on key challenges and opportunities that attend bringing the two broad fields together for mutual enrichment and building a new, hybrid field of study. Underlining the co-constitutive nature of performance and politics, the introduction suggests that such a framework is critical to promoting an interdisciplinary approach to understanding the complex political world of the twenty-first century.
