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.     

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.     

Business Backgrounds and Congressional Behavior

In the following paper, we analyze whether the behavior of members of Congress with business backgrounds differs from that of other legislators, and we find that it does. Specifically, House members with business backgrounds have closer relationships with business interests (as measured by larger contributions from corporate PACs) and demonstrate more probusiness roll call voting. We also find that members making a direct transition from a business career to the House sponsor more business-focused legislation. The significance of a business background is consistent across different forms of behavior, though the magnitude of effects is generally modest. Our findings contribute to a growing body of literature emphasizing the importance of legislator backgrounds to their behavior in office.

Republican Pete Coors brings it up in nearly every campaign speech: There are too many lawyers in the U.S. Senate.... His point is that he'd like to see more successful businesspeople running the country the same way they guide their companies. (Florio 2004)     

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.     

Performance of different luminescence approaches for the dating of known-age glaciofluvial deposits from northern Switzerland

Luminescence properties of two samples taken from sand lenses in proglacial outwash de-posits of a piedmont glacier that reached the Swiss midlands during the Last Glacial Maximum are investigated in detail. Deconvolution of CW-OSL decay curves shows that the fast component dominates the OSL signal of quartz. The chemistry of single feldspar grains, in particular the K content in different grains, is determined using wavelength dispersive spectrometry (electron microprobe), revealing an average 12.9 wt.% K of the grains contributing to the IRSL signal. D _e distributions are investigated in order to gain insights into partial bleaching, and agreement is found for quartz OSL and feldspar IR₅₀ and pIRIR₂₂₅ ages for small aliquots and single grains when applying the Minimum Age Model. These ages are also consistent with independent age control. For one sample, ages determined using the Central Age Model result in highly overestimated ages for both feldspar and quartz.     

Landlord Villages of Iran as Landscapes of Hierarchy and Control

This paper analyses the walled landlord villages of the Tehran Plain in terms of hierarchy and control, and how these structures are created and expressed through the spatial landscape of the villages. Drawing on original fieldwork, the ways in which landlords used the physicality of the villages to maintain and reinforce control over farmers is explored. We suggest that the “success” or at least longevity of the land tenure system in Iran prior to the later twentieth century can be attributed at least in part to the buildings and spaces of the villages themselves.
