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.     

Quantifying woodland resource usage and selection from Neolithic to post Mediaeval times in the Irish Midlands

The antiquity and context (site or feature type) are the two principal factors that act as a framework for interpreting charcoal and wood data from archaeological sites in the recreation of past woodland environments. This research addresses these parameters through the analysis of over 18,000 charcoal fragments from 57 archaeological excavations carried out along a 61?km road scheme in the midland region of Ireland. Observations on spatial vegetation dynamics and woodland resource patterns are also reported on. The data were analysed through percentage frequency and multivariate analyses. The results reveal woodland resource usage in terms of wood types selected for use as fuel or as structural wood as well as patterns of change and variability in taxonomic composition in relation to site types, feature types and time periods. Selection was found to be low in prehistoric times and in particular at burnt mound sites/fulachta fiadh but became increasingly important as time progressed. This has important implications when charcoal from archaeological settings is used in environmental reconstructions.     

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.     

The Mesolithic–Neolithic Transition in the Channel Islands: Maritime and Terrestrial Perspectives

This paper investigates the Mesolithic–Neolithic transition in the Channel Islands. It presents a new synthesis of all known evidence from the islands c.5000–4300 bc , including several new excavations as well as find‐spot sites that have not previously been collated. It also summarizes – in English – a large body of contemporary material from north‐west France. The paper presents a new high‐resolution sea‐level model for the region, shedding light on the formation of the Channel Islands from 9000–4000 bc . Through comparison with contemporary sites in mainland France, an argument is made suggesting that incoming migrants from the mainland and the small indigenous population of the islands were both involved in the transition. It is also argued that, as a result of the fact the Channel Islands witnessed a very different trajectory of change from that seen in Britain and Ireland c.5000–3500 bc , this small group of islands has a great deal to tell us about the arrival of the Neolithic more widely.     

An Independent Palestine: The Security Dimension

If negotiations produce an end to the Israeli–Palestinian conflict then a sovereign, independent Palestine may emerge. But what is required for it to succeed? Nothing is more important than the security of a Palestinian state–for itself, for Israel, and for the region: security trumps all else. In addition to the problem of dealing effectively with opposition to a peace agreement within Palestine or directed against it from outside, the nature and magnitude of the security challenge will depend in large part on three issues: the drawing of borders between Israel and Palestine–and whether they are porous or marked by a rigid line of barriers; whether Israeli settlements are withdrawn, or in part incorporated into Israel, perhaps through land swaps with Palestine; and what arrangements are made for Jerusalem. One answer is the creation of effective Palestinian military forces (in addition to police), but this course could be divisive; a second is the development of a series of Israeli–Palestinian confidence‐building and share–security measures, including intelligence cooperation; a third is progress towards reducing external threats to Israel–Palestine, including success in Iraq and in defusing other Middle East problems. Most useful, however, would be the creation of an American‐led peace enabling force, ideally modelled on NATO. This force would need to be agreed by both Israel and Palestine; it must be adequately staffed, trained and equipped; its duties and rules of engagement must make sense to all parties; and it must be part of a network of dispute‐resolution and confidence‐building measures in full partnership with Israeli and Palestinian authorities.     

A Forest of Contradictions: Producing the Landscapes of the Scottish Highlands

While total global forest cover is decreasing, in many parts of the world forests are on the rebound. Uncritical examinations of this phenomenon credit the benign diffusion of capitalist development for this "forest transition." More critical readings of this question—including green Marxian and poststructuralist approaches—might conclude something very different, however. In this paper, we explore the question of expanding forest cover, using the case of the Scottish Highlands, where forestland has tripled since the 1920s, in an attempt to critically explain regional land–cover change. Drawing upon historical sources and Scottish Executive and Forestry Commission data, we examine the specific environments currently forming in the Highlands under conditions of economic change. We conclude that two divergent forestry practices and ecologies have been formed in the wake of economic restructuring: those geared towards industrial production and those targeted at consumption through ecotourism. We conclude, therefore, that capitalism's spatial fix to declining industrial power in the region is an inherently ecological one that takes the form of "schizophrenic forestry," in which forest expansion leads to the rise of degraded monocultures alongside "pristine" sites of conservation.
