<p>The Industries of Angkor Project (INDAP) is the first intensive investigation into the history and role of iron production at Preah Khan of Kompong Svay (Preah Khan), the largest regional enclosure complex built by the Angkorian Khmer (9<sup>th</sup> to 15<sup>th</sup> c. CE) in Cambodia. We present the initial multidisciplinary research of the primary iron smelting sites located on Boeng Kroam, a large reservoir located north of Preah Khan’s central temple complex. Ground-penetrating radar surveys and excavation at Location 1, a slag concentration on top of the reservoir bank, revealed that it is a deposit of metallurgical waste from a nearby furnace. Multiple radiocarbon dates from Location 1 indicate that the smelting activities took place in the early 15<sup>th</sup> century during the time of Angkor’s ultimate collapse as the political centre of the Khmer world. This indicates a re-use of spaces by iron workers after the primary occupation of Preah Khan between the 11<sup>th</sup> and 13<sup>th</sup> centuries.</p>

Our recent discovery and excavation of a series of iron smelting furnaces, dated to the eighth and ninth century CE, near upland Rmet villages in northwest Laos, potentially sheds new light on the role of regional upland groups during the immediate pre-Tai period. The oral tradition associated with these furnaces emphasises the role of an ancient population of metallurgists who left the area under pressure from the Rmet. These stories could refer to the actual arrival and departure (immigration and emigration) of a population of metallurgists in that area sometime during the second half of the first millennium CE or they can support the scenario of a dissimilation process. The latter would explain the existence of a Rmet subculture that the locals regard as ‘Chueang Lavae’ villages, a differentiation that Karl G. Izikowitz had labelled ‘Upper Lamet’ in the 1930s. Our finds show that archaeology and ethnology can both contribute to a much-needed reformulation of upland Lao history.

Smelting Activity

In southwestern Niger, near Niamey, several thousand singleuse bloomery furnaces have been mapped and identified. The archaeological study of approximately 30 furnaces and their slag reveals the existence of four methods for iron smelting: three types of pit furnace and one slag-tapping type. The slag pit furnaces are clearly differentiated by the form and volume of their pits. All slag-tapping furnaces drain off slag through small openings. The slag is tapped either vertically or laterally. According to radiocarbon dates, the smelting activity developed in the 2nd century AD and intensified through to the 14th century. It continued to evolve until the middle of the 20th century. The low intensity of iron production for these furnaces indicates the products were intended mainly for the local market.

Ideal Dielectric

Within the ground penetrating radar bandwidth the medium is considered to be an ideal dielectric, which is not always true. Electromagnetic waves reflection coefficient conductivity dependence showed a significant role of the difference in conductivity in reflection strength. It was confirmed by physical modeling. Conductivity of geological media should be taken into account when solving direct and inverse problems, survey design planning, etc. Ground penetrating radar can be used to solve the problem of mapping of halocline or determine water contamination.

PurposeThis paper explores the dissonance between co-production and expectations of impact in a research project on student loneliness over the 2019/2020 academic year. Specific characteristics of the project – the subject matter, interpolation of a global respiratory pandemic, informal systems of care that arose among students and role of the university in providing the context and funding for the research – brought co-production into heightened tension with the instrumentalisation of project outputs.Design/methodology/approachThe project consisted of a series of workshops, research meetings and mixed-methods online journalling between 2019 and 2020. This paper is primarily a critical reflection on that research, based on observations by and conversations between the authors, together with discourse analysis of research data.FindingsThe authors argue that co-producing research with students on university contexts elevates existing tensions between co-production and institutional valuations of impact, that co-production with students who had experienced loneliness made necessary space for otherwise absent support and care, that the responsibility to advocate for evidence and co-researchers came into friction with how the university felt the research could be useful and that each of these converging considerations are interconnected symptoms of the ongoing marketisation of HE.Originality/valueThis paper provides a novel analysis of co-production, impact and higher education in the context of an original research project with specific challenges and constraints. It is a valuable contribution to methodological literatures on co-production, multidisciplinary research into student loneliness and reflexive work on the difficult uses of evidence in university contexts.

ABSTRACT This paper presents new results of radiocarbon (14C) ages from archaeological sites in northern Igboland. The study was designed to shed more light on early human occupation and activities in the study area based on sediments from cave and iron-smelting sites. The approach consisted of ethnographic, archaeological, palynological, and slag analyses; these were complemented with 14C dates. The technology adopted as well as the paleoenvironmental conditions that prevailed during the period of human settlement in both sites was revealed. These data, complemented by 14C dates, highlight the human behavioral and subsistence patterns within the region and are comparable to those from similar sites in southeastern Nigeria.
