An experimental approach has been used to establish whether medieval ironworking activity could be identified in peat bogs using mineral magnetic measurements. The research project comprised three elements. First, magnetic susceptibility and remanence properties were obtained for materials from an experimental iron smelt, in a furnace of medieval design, and from material collected during the excavation of the medieval bloomery at Llwyn Du in Coed y Brenin, Snowdonia. Materials sampled and measured included charcoal, aerial dust, roasted bog ore and furnace dust. A second experiment determined whether small amounts of aerial dust released from the furnace could be detected in accumulating peat samples. This was achieved by sprinkling small quantities of dust on to a constructed ’peat core’ that had no detectable magnetic signature prior to the addition of the dust. The application rates used were within the range expected to fall on a peat bog located close to a medieval furnace. Thirdly, mineral magnetic measurements were made on a peat core collected close to the Llwyn Du bloomery. The results confirm that roasted bog ore, aerial dust released from and dust accumulating in the furnace after a smelt, are magnetically detectable. The aerial dust and roasted bog ore produced enhanced susceptibility and remanence signatures in the constructed ’peat core’ experiments. Peaks in IRM(0.88T) and HIRM were measured in the Llwyn Du peat monolith and appear to correlate with a time when the medieval bloomery was operational. The results presented here suggest that it is possible to identify evidence of past ironworking in peat bogs using mineral magnetic measurements and that the signatures remain well preserved in the peat record even after burial for several hundred years. 相似文献

Discourses on “illegal” or informal small-scale mining (galamsey) have presented it largely as a menace. Using Ghana as the focus of our study, we present a counter-narrative to the predominant discourse. Employing qualitative in-depth interviews with 193 local galamsey operators, the study found that economic factors coupled with the combative posture of state regulatory agencies explain the persistence of illegal activity. Although galamsey is not problem-free, the study revealed it is the livelihood support base of such communities, providing jobs and incomes to many households. Since mineral-rich local communities, at least, in part, depend on galamsey, the state and its regulatory agencies could collaboratively work with local agencies and mineral-rich communities to fully exploit the hidden treasures in galamsey while reducing the proximate negative effects. 相似文献

Public authority beyond the state has often been seen as isolated from the state and/or constituting a threat to the state. Recent scholarship, however, has started to conceptualize ‘state’ and ‘non‐state’ forms of public authority as closely connected and interdependent. This article contributes to this theoretical shift by means of a qualitative case study of public authority in Palestinian refugee camps in South Lebanon. Lebanon's Palestinian camps are routinely characterized as ‘states‐within‐the‐state’, undermining the sovereignty of the Lebanese state. Yet, as this article demonstrates, both a generic state idea and the specific Lebanese state system constitute crucial benchmarks for the Popular Committees that govern informal Palestinian settlements. The article therefore conceptualizes the Popular Committees as ‘twilight institutions’ and explores the ‘languages of stateness’ that they adopt both communicatively, vis‐à‐vis Palestinian competitors, and coordinatively, vis‐à‐vis Lebanese counterparts. This reveals that the Popular Committees emulate the Lebanese state institutions they come into contact with, to bolster their own authority. They do this partly to be viable interlocutors for Lebanese state institutions; this suggests that the Popular Committees’ non‐state authority might validate rather than challenge state authority in Lebanon, and that state and non‐state authority can be mutually constitutive. 相似文献
