The dynamics and livelihood implications of illegal mining in Ghana: A critical assessment

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.     

Multi-method Analysis of Avian Eggs as Grave Goods: Revealing Symbolism in Conversion Period Burials at Kukruse,NE Estonia

Eggshells are unusual finds in the Iron Age of eastern Europe (500 BC–1200 AD) deserving extra attention in terms of analysis as well as interpretation. This paper discusses two rare eggshell finds, discovered in female burials at the conversion period (12th–13th century AD) cemetery at Kukruse, NE Estonia. Our multianalytical study combining FT-IR, SEM(-EDS), microscopy and ZooMS provides an overview of methods applicable for identifying egg species, their predepositional history and curation. Based on the analytical results and the comparative analysis of the content and context of these two burials, we argue that different aims and connotations lay behind depositing eggs as burial goods, allowing well-supported interpretations of both pagan and Christian religious worldviews simultaneously.     

Magnetite grain-size analysis and sourcing of Mediterranean obsidians

The potential of magnetic grain-size variations as an obsidian source characteristic is investigated using geological and archaeological obsidians from five islands of the Mediterranean Sea: Lipari, Sardinia, Palmarola, Pantelleria, Melos. Four parameters are used: magnetic (χ) and anhysteretic (χ_a) susceptibilities, saturation isothermal remanent magnetizations at room (SIRM₂₉₃) and liquid nitrogen (SIRM₇₇) temperature. The ratio S_T = SIRM₇₇/SIRM₂₉₃, which depends on the superparamagnetic grains relative abundance, varies little in each individual site, with the exception of Lipari which is characterized by large variations and the highest content of superparamagnetic grains. The χ_a vs. χ plot ( King et al., 1982) shows some within-site dispersion of the samples; but the ratio Q_a = χ_a/χ, which is strongly influenced by the single domain grains content, is characteristic for each site. The combined use of the King and Q_a vs. S_T plots discriminates the samples from most of the sites and suggests that the grain-size analysis is a promising approach in sourcing obsidian archaeological artefacts. Moreover, the measurements of the four parameters used are simple, quick and feasible with no or little damage to archaeological finds.     

The Battle of Saipan in Japanese Civilian Memoirs: Non-combatants,Soldiers and the Complexities of Surrender

In Japan, ‘Saipan’ refers both to a nearby tropical holiday, and to the site of a battle that annihilated Japanese troops, embroiled the large population of Japanese residents on the island and ultimately spelled the end of the Japanese empire, now within the reach of bombers. In other places, and particularly amongst the Allies, Saipan conjures up images of civilians jumping to their death rather than facing capture, leading to simplistic assessments about fanaticism being rife across all sections of Japanese society; to a focus on suicide that overshadows the true extent of the battle’s collateral damage; and to largely unexamined statements about military exploitation of civilians and the murder of civilians in extremis. This article uses the memoirs of civilian survivors of the battle to reflect on the civilian experience of the battle of Saipan, relationships between Japanese combatants and non-combatants during the fighting, and the complexities of surrender.     

Archaeometric study of natural hydraulic mortars: the case of the Late Roman Villa dell’Oratorio (Florence,Italy)

This paper shows the results of a multidisciplinary study carried out on the mortars from the Late Roman Villa dell’Oratorio (fourth-sixth ad), an aristocratic mansion built in the lower Valdarno (Florence, Italy). Thirty-one bedding mortar and plaster samples were analysed through optical microscopy, thermogravimetric analysis, X-ray powder diffraction and scanning electron microscopy with energy-dispersive X-ray spectroscopy for determining the chemical, mineralogical and petrographic characteristics, while their main physical properties were measured by geotechnical procedures. The collected data indicates that the analysed mortars are made up of very fine to coarse river sand aggregate mixed with white to yellowish-white natural hydraulic lime binder mainly consisting of mixtures of prevailing calcite and hydraulic compounds. With regard to the origin of the raw materials, the aggregates were recognized to be selected Arno river sands, and the binders are the burning product of a local marly limestone (ex Alberese). Therefore, the mortars of the Late Roman Villa dell’Oratorio are one of the first uses of natural hydraulic lime in the lower Valdarno.
