Metallurgical study on some Sasanian silver coins in Sistan Museum

Elemental analyses and microstructural studies of historical metal artifacts provide researchers with invaluable and priceless information about metal extraction technology and the procedure of creating artifacts. In addition, the information is helpful for knowing about the metallurgical processes of the artifacts. This study was conducted by a microscopic examination and elemental analyses of seven Sasanian silver coins preserved in the Sistan Anthropology Museum, Iran. For the purpose of this study, three methods were employed: first, the proton induced X-ray emission microanalysis (micro-PIXE), to determine the main and trace elements of the coins; second, scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS), to perform elemental analysis to identify impurities of the metal; and third, microstructural analysis of the coins which was carried out with an optical microscope (OM). The elemental analyses identified Ca, Cu, Ag, Au, and Pb in the coins. The high quantity of Ag in samples validated the application of advanced and accurate cupellation technology for refining silver and separating impurities from raw ore. The gold concentration in the coins indicated the use of non-galena ore for silver extraction. Additionally, the microstructural analyses of samples pointed to the application of thermo-mechanical processes on coins.     

Sex estimation using cervical dental measurements in an archaeological population from Iran

Sex estimation of skeletal remains is one of the major components of forensic identification of unknown individuals. Teeth are a potential source of information on sex and are often recovered in archaeological or forensic contexts due to their post-mortem longevity. Currently, there is limited data on dental sexual dimorphism of archaeological populations from Iran. This paper represents the first study to provide a dental sex estimation method for Iron Age populations. The current study was conducted on the skeletal remains of 143 adults from two Iron Age populations in close temporal and geographic proximity in the Solduz Valley (West Azerbaijan Province of Iran). Mesiodistal and buccolingual cervical measurements of 1334 maxillary and mandibular teeth were used to investigate the degree of sexual dimorphism in permanent dentition and to assess their applicability in sex estimation. Data was analysed using discriminant function analysis (SPSS 23), and posterior probabilities were calculated for all produced formulae. The results showed that incisors and canines were the most sexually dimorphic teeth, providing percentages of correct sex classification between 86.4 and 100 % depending on the measurement used. The combination of canines and other teeth improved significantly the level of correct sex classification. The highest percentages of sex classification were obtained by the combination of canines and incisors (100 %) and canines and molars (92.3 %). The present study provided the first reference standards for sex estimation using odontometric data in an Iranian archaeological population. Cervical measurements were found to be of value for sex assessment, and the method presented here can be a useful tool for establishing accurate demographic data from skeletal remains of the Iron Age from Iran.     

Identifying handedness at knapping; an analysis of the scatter pattern of lithic remains

Determining hand laterality during human evolution is important in order to identify brain hemispheric lateralization for motor tasks and, indirectly, to gain information on the complex cognitive functions of the human brain. In this paper, we present a new method for inferring handedness from lithic evidence. The study is based on an analysis of the scatter patterns of lithic remains from stone-knapping episodes. An experimental programme was carried out by 14 knappers (eight right-handed and six left-handed), ranging from individuals that had never even struck two pebbles together to individuals who were quite familiar with prehistoric tools and had some degree of practice. The results of the experiment show that the material scatter patterns of right- and left-handed knappers at group level are different, but they do overlap at certain intervals. At the individual level, the probability of falsely ascribing left- and right-handedness has also been estimated. In addition, we have adapted this method to be applied to the archaeological record. In this case, only well-preserved knapping events with no post-depositional alterations can be used to assign left- or right-handed knappers, with the former being more reliably detected than the latter.     

Genealogies of Practice in and of the Environment in Banda,Ghana

Despite recent emphases on both environmental archaeology and practice theory in archaeology, the two are rarely combined. In this paper, we illustrate a genealogies of environmental practice approach that seeks to understand how human actions grounded in familiar repertoires make sense of environmental and political economic change. Employing archaeobotanical and zooarchaeological data, we first examine taxon-specific genealogies of practice and then compare them to one another as well as to broader climatic, political, and economic contexts of the last millennium in Banda, west central Ghana. In focusing on the interactivities between different kinds of data, we coax out the strategies used by Banda’s inhabitants to cope with fluctuating environmental and political conditions. We argue that during a several centuries long drought in the fifteenth to seventeenth centuries ad, Banda villagers took advantage of a diverse set of economic activities to cope with turbulence, but by the late nineteenth century, these opportunities had dwindled, diminishing the villagers’ practical options.     

Her Mirror,His Sword: Unbinding Binary Gender and Sex Assumptions in Iron Age British Mortuary Traditions

At the site of Hillside Farm, Bryher, on the Isles of Scilly, a materially rich single Iron Age inhumation was discovered containing the unsexable fragmented remains of one adult with a number of high-quality metal grave goods including an iron sword with a bronze scabbard and a bronze mirror. Swords and mirrors have long been considered high-status, oppositionally gendered grave goods that crosscut regional divisions in the pre-Roman British Iron Age (c. 800 B.C.–A.D. 43). Their combined presence within the burial of a single individual represents a touchstone within the ongoing unraveling of a long-held, interconnected set of reified binary sex and gender assumptions that have permeated discussions of British Iron Age mortuary contexts. In better recognizing this web of “binary binds,” we can deconstruct the a priori, exclusionary, interconnected sex and gender assumptions that configure how we investigate the terms of engagement between materials and persons in these burial contexts. Crucial to this analysis is an approach to patterning that (1) does not begin with a search for sex and gender as evidence of male and female dichotomies, (2) sees the potentiality for any component of a mortuary assemblage to have multiple points of significance, and (3) embraces data ambiguity. Developing such critical approaches will ultimately contribute to the deployment of more inclusive forms of analysis that do not reify sex and gender as the primary organizing principles within mortuary contexts, aiding scholars in avoiding assumptions that bind sex and gender analyses into artificially binary paradigms.     

The Poetics of Devotion in ʿĀʾisha al‐Bāʿūniyya's Praise of God and Muḥammad

Recently, there has been an effort within Islamic Studies to reassess the common belief that the so‐called ‘post‐classical’ era of Islamic history was characterized by intellectual stagnation and decline. The Mamluk era is one such period that has suffered from a dearth of scholarly attention resulting from outdated stereotypes. This article contributes to scholarship on this era through examining some poems by a late Mamluk poet, ?ā?isha al‐Bā?ūniyya (d. 1517). While much scholarship on al‐Bā?ūniyya focuses on her lyrical mystical verse, the poems studied here incorporate selective allusions to key Islamic sources in order to narrate a history of divine favor as the speaker imagines it. This innovative history expresses a poetics of devotion that focalizes Mu?ammad and the poet's own peers. The poems intertextually anchor this narrative in key Islamic sources, reflecting al‐Bā?ūniyya's extensive scholarly training. They constitute an unusual example of a female poet writing beyond the genres with which women's premodern poetry is conventionally associated. This poetry also represents a post‐classical contribution to Islamic literary and religious history. However, the criterion of originality should ultimately be reconsidered in evaluations of scholarly merit, and scholarship should pay more attention to continuities and intertextuality in texts.     

Margaret Cavendish contre Robert Hooke : Le duel impossible

In 1665, Robert Hooke published his major work in microscopy, Micrographia, a defense of experimental philosophy. The following year, Margaret Cavendish, Duchess of Newcastle, published at her own expense a treatise and a novel that undermined the basis of this new science. The dispute broke out at the initiative of the Duchess, in the context of a vast controversy about the legitimacy and the efficiency of optical instruments in natural philosophy. All the figures of the dual are used, except one: the counterattack. Cavendish, indeed, was alone on the battlefield. Is it possible to call a dual a battle with only one combatant? This particular case of dispute that stops owing to the shortage of combatants is the subject of this article.     

Auf gute Nachbarschaft!

Companies' community involvement turns out to be spatially relevant and–in many cases–to be focused on the near surroundings of the place of business. Some companies strategically align their involvement in order to systematically address local challenges. The essay at hand addresses the subject of corporate social responsibility from a local development perspective. Using the example of two family-owned enterprises based in Duisburg, Haniel and Grillo, it illustrates how socially committed companies can get involved with their local community by acting as good neighbours. Furthermore, it argues that socially committed companies can function as producers of space concerning matters of urban and local development. The specific local settings as well as the economic conditions of the local community serve as an explanatory background of the companies' involvement. The cases presented in this paper prove the firms' specific knowledge of local development needs and possibilities. This makes them qualified partners for local government actors and civil society actors. Thus, in the future, it is worth addressing corporate local responsibility from a governance point of view both in theory and in practice.
