Investigating the production provenance of iron artifacts with multivariate methods

The quest for suitable data, data treatments and statistical methods for identifying the provenance of iron artifacts has led to a variety of analytical strategies. Researchers working on the problem have been slow to develop or adopt the use of multivariate statistical techniques, despite their successful implementation in other archaeomaterials sourcing frameworks. This paper explores the analytical potential of a comprehensive multivariate statistical strategy for identifying the primary production origins of bloomery iron artifacts using bulk chemical analyses of bloomery smelting slag and slag inclusions in iron artifacts. This strategy includes a multivariate model for identifying distinct slag inclusion types introduced during smelting and refining. Principal component analysis and linear discriminant analysis are then applied to smelting slag training sets to create multivariate provenance fields, the chemical distributions of which are defined by kernel density estimation. Single and multi-group evaluation methods are examined. Appropriate data transformations are discussed to facilitate the projection of the chemistry of “unknown” slag inclusions into the multidimensional space generated by the smelting slag groups of known provenance. The efficacy of this strategy is demonstrated through its application to a previously examined data set derived from three iron production experiments and a published archaeological example. Results indicate that an appropriately designed multivariate strategy can be an effective tool for evaluating provenance hypotheses for bloomery iron artifacts.     

ANTHROPOGENIC ENVIRONMENTAL ALTERATION OF THE SEA OF AZOV

The authors concentrate on four aspects of environmental alteration of the Sea of Azov. First, they trace the Azov's problems back to Soviet resource-use conflicts. Second, they present several examples of anthropogenically induced environmental disruption of the Azov's ecosystem. Third, modeling is utilized to project possible future salinity conditions within the Azov. Fourth, in their attempt to evaluate the various ameliorative efforts that have been made or are being proposed, they challenge the overall ecologic-economic effectiveness of the proposed dam across the Kerch' Strait designed to regulate the salinity of the Azov. Finally, they conclude it is unlikely that the Azov ever will be returned to its previous “natural” condition. This article should be read in conjunction with Pecherin's article also in this issue of Soviet Geography. (Illustrations by Elinore Mathews, University of Washington, Seattle.)     

The United Kingdom and the Negotiation of the 1969 New York Convention on Special Missions

During 1968–9, members of the United Nations, meeting in the Legal Committee of the General Assembly, negotiated a Convention on Special Missions, sometimes known as the New York Convention, setting out the privileges and immunities of ad hoc embassies between states. The negotiation was part of a process through which the UN sought to clarify the status and rights of official representatives, so that diplomacy could function with security and certainty. This article looks at the role of one leading power, the United Kingdom, in the talks. It explores how British interests were defined, the tactics used to secure them and how London came to terms with pressure from other states to redefine its approach. The focus is on the overall political thrust of the British negotiating position, as formulated mainly by the Foreign Office, rather than the detailed talks on such thorny issues as tax avoidance and diplomatic property. The article shows that, while London was keen to see a codification of diplomatic law, cold-war considerations made it less than enthusiastic about an upsurge in the number of special missions that the New York Convention might encourage.     

Placing Managua: a landscape narrative in post-earthquake Nicaragua

On 23 December 1972, a major earthquake occurred near Managua, Nicaragua. Followed by two strong aftershocks, the earthquake had devastating consequences for the people of Nicaragua's capital, and corruption and mismanagement during the relief efforts gave impetus to what would become the Nicaraguan Revolution of 1979. The earthquake also dramatically altered the landscape of the capital, destroying most of the city's historic center. Abandoned after the earthquake, the area nevertheless maintains a prominent symbolic role in Nicaragua, and in many ways remains the heart of a vastly changed modern city. The revolution was celebrated in the historic core, and memorials, government buildings, and ongoing revitalization efforts have all shaped it in the nearly four decades since its devastation. Though initially abandoned, it remains a powerful and dynamic place. This article investigates landscape transitions in the historic heart of Managua since the tumultuous events of the 1970s, with particular emphasis on the ways in which visions of Nicaragua's past, present, and future are reflected in the competing currents of the built landscape.     

Seismic Site Response Modeling for Three Missouri River Highway Bridges

Three highway bridges spanning the Missouri River flood plain were selected for evaluation of seismic site response for moderate size earthquakes emanating from the New Madrid Seismic Zone (NMSZ) in the Midwestern United States. The NMSZ is known to be capable spawning earthquakes larger than magnitude (M) 7.0, four of which occurred in a three-month period between 1811 and 1812, and the M_w 6.0 earthquake of October 1895 centered near Charleston, Missouri. This study evaluated the likely impacts of long period motion of these historic earthquakes on three long-span highway bridges using geotechnical data obtained from recent investigations. Our results suggest site amplification between 6× and 9×, depending on the magnitude and epicentral distance. We believe that threshold magnitude for serious foundation failure and damage to these bridges is between M_w 6.5 and 6.6. Above these magnitudes widespread liquefaction is predicted, which would effect the peak horizontal acceleration and spectral accelerations, causing the ground motions to be different than predicted. Increase in amplification of the response spectra also should be expected where the periods are higher than 1.0 sec. Therefore, M_w 6.5+ earthquakes at ranges 210–260 km could be expected to engender resonant frequency problems for multiple span bridges and tall buildings (10 to 25 stories) in channel corridors containing 20 to 46 m of unconsolidated sediment.     

Sexual harassment in Korean college classrooms: how self-construal and gender affect students' reporting behavior

This article examines the reasons why women students may hesitate to report sexual harassment. The research draws on the notion of ‘self-construal’. Self-construal is a form of self-identification in social relationships, which in this case relates, in particular, to gender within cultural environments in Korea. For the purposes of this research, a survey was conducted with 298 Korean college students from 7 to 14 March 2006. The results showed that different types of self-construal had different influences on Korean college students' and their reporting of sexual harassment, whereas gender did not. Grounded in the theoretical framework of self-construal, people with independent self-construal were found to express their uncomfortable feelings and to report to the university counseling center, whereas people with interdependent self-construal did not. Furthermore, we found that women were more likely than men to directly express their opinions and report sexual harassment to the university counseling center. Men are also harassed by women colleagues or students but are often more reluctant than women to recognize their experiences as ‘sexual harassment’ because of the stereotype that men are the perpetrators of this behavior, not its victims, and because they fear ‘loss of face.’ It is necessary to engage not just with femininity but also with masculinity and the relationship between these constructs because they are both temporally and geographically contingent.     

Life in a “Cathedral of Consumption’: Corporate and Personal Material Culture Recovered from a Cellar at the Robert Sayle Department Store in Cambridge, England, ca. 1913–21

An early twentieth-century assemblage dating to ca. 1913–21 associated with staff that worked for and lived in the associated hostel of the Robert Sayle department store in Cambridge, England, contained a mixture of material that was supplied by the business for communal activities and personal items. The contrast between these two types of material allows the relationship between the business and its staff to be explored. The assemblage is also considered in terms of the class, gender and age composition of the hostel population and the concept of resistance.
