Internal oxidation of cast iron artifacts from an 18th-century steel cementation furnace

Heavily corroded metal artifacts recovered from the site of an 18th-century steel cementation furnace in Trenton, New Jersey, are cast iron altered by internal oxidation. The progress of the internal oxidation process was followed by comparison with the microstructure of cast iron exposed to high temperature in a wood-burning fireplace. The graphite flake structure of the cast iron allows deep, rapid penetration of oxygen that reacts at the iron–carbon interfaces within the iron to form iron oxides that eventually replace the graphite flakes. Microprobe analyses show that the silicon in the cast iron is converted to knebelite that also serves as the host for phosphorus. Sulfur dispersed in the internal oxidation product and porosity appear to be responsible for rapid rusting of the artifacts. Internal nitriding accompanies the oxidation. The Trenton artifacts are interpreted as grate bars from the fire box of a cementation furnace.     

Energy dispersive X-ray fluorescence analysis of 1st millennium ad glass from Britain

A series of energy dispersive X-ray fluorescence analyses has been undertaken in response to archaeological problems relating to 1st millennium AD glass excavated in Britain. The aim of the work was to furnish a set of comparable analytical results to be used in assessing hypotheses concerning the general state and development of glass technology through this period. Within this framework, however, it has also been possible to attempt answers to specific archaeological questions relating to material from particular sites. The paper discusses the background to, and the interpretation of such results, particulars of the analytical technique used, a general overview of approximately 200 analyses and three examples of the use of this data in relation to specific archaeological problems.     

“Protect the women!” Trans-exclusionary feminist issue framing and support for transgender rights

An increasingly salient policy innovation pursued by LGBT+ rights groups and socially liberal policy entrepreneurs is the right of trans people to bring their legally recorded sex in line with their lived gender by way of self-identification. In response to these moves toward trans inclusion, a unique coalition of trans-exclusionary (gender critical) feminists and traditionalist conservatives has emerged to challenge these reforms. This coalition of policy opponents, mirroring historical issue frames that present homosexuals as predatory sexual deviants, campaign on a salient issue frame that presents transgender individuals and the expansion of trans rights as an inimical threat to the security, safety, and welfare of (cisgender) women, particularly in single-sex spaces. In this paper, we address two questions. First, we ask: do trans-exclusionary “protect women” issue frames over the alleged threat of trans persons to (cis) women shape mass public opinion? Second, we ask: in a relatively LGBT+ friendly policy environment, who supports the right to self-identification for trans individuals? We answer these questions via an original pre-registered survey experiment embedded within the 2021 Scottish Election Study. We find that trans-exclusionary issue frames appealing to (cis) women's safety significantly depress support for trans rights, particularly among women respondents. Highlighting these concerns is an effective means of increasing already robust opposition to reforms designed to improve the welfare of transgender individuals, which should be of concern for proponents of self-identification policies.     

Can Christian Democracy Be America's Next European Import?

The confluence of the Supreme Court's Obergefell decision on gay marriage and the unusual nature of the 2016 U.S. presidential election presents American Christians with significant political questions. Obergefell's elevation of gay marriage to the status of a constitutional civil right put U.S. law and Christian orthdoxy at loggerheads, thereby raising serious issues with regard to the continued ability of religious organizations to participate in the not-for-profit sector and in higher education. At the same time, the nationalistic turn of the the Republican party under Donald Trump generated dissonance with Christian views of human solidarity. The new situation seems to shift the landscape of American politics and raises the possibility of new alternatives. Contributors to this symposium were asked to evaluate the prospects for an Americanized version of European Christian Democracy. While they generated a diversity of opinion about Christian Democracy, the group pragmatically recognized the many obstacles in place. Some argued against the idea because of reservations about associating the Christian faith with the coerciveness of law. Others noted the proven virtues of such parties in Europe. This article interacts with the different responses and makes a case for why Christian Democracy might have a brighter future in the U.S. than many believe. The primary reason is that Christian Democracy emerged in response to aggressive secularism in Europe's past that may only be reaching similar levels in the U.S. today. Therefore, a new political movement with similarities to Christian Democracy might make sense in the American context.
