Abstract In this paper we analyzed a batch of 64 clay weights from three archaeological sites located in Romania (Gumelniţa, Măgura-Jilava, and Sultana) that belong to Kodjadermen-Gumelniţa-Karanovo VI cultural complex (4600–3900 cal. BC). Our approach includes an interdisciplinary investigation based on technological analysis, experimental archaeology, and X-ray CT scans coupled with statistical analysis. This investigation has a high potential to reveal relevant information regarding the technological background (e.g., inclusion, voids, temper, etc.), manufacturing stages (e.g., modeling, shaping, kneading, etc.), or transformation processes (e.g., drying and firing vs. weight and size modification) in order to identify, explain and understand the chaîne operatoire for this type of artefacts. Moreover, correlation of the results with the experimental archaeology could offer an integrative interpretation about the material culture of past humans and its multiple meanings, but also critical information about the multiple dimensions of manufacture for these objects (e.g., time, effort, physical–chemical processes, etc.). The multi-analytical approach proposed here also includes a comparative study of technological aspects of these clay weights across the three archaeological sites investigated, as well as the experimental replicas.

New Caledonia is the southern-most archipelago of Melanesia. Its unique geological diversity, as part of the old Gondwana plate, has led to specific pedological and floral environments that have, since first human settlement, influenced the ways Pacific Islanders have occupied and used the landscape. This essay presents some of the key periods of the nearly 3,000 years of pre-colonial human settlement. After having presented a short history of archaeological research in New Caledonia, the essay focuses first on the Lapita foundation, which raises questions of long-term contacts and cultural change. The second part details the unique specificities developed during the “Traditional Kanak Cultural Complex,” during the millennium predating first European contact, as well as highlighting the massive changes brought by the introduction of new diseases, in the decades before the colonial settlement era. This leads to questions about archaeological history and the role of archaeology in the present decolonizing context.

Ostrich Eggshell

The Neolithic site KS043, excavated by the Institut français d'archéologie orientale (IFAO), is situated in the southern basin of the Kharga Oasis (Egypt). It is one of the very few stratified prehistoric sites of the eastern Sahara. The archaeological remains were found near artesian springs that provided water for pastoralists during the dry Middle Holocene. In situ settlement features provided well-preserved material (charcoal, ashy sediment, ostrich eggshell) sufficient to perform radiocarbon dating in the IFAO laboratory in Cairo by the conventional liquid scintillation method. In 2 cases, ostrich eggshell and charcoal within the same in situ context gave significantly different results of, respectively, ∼600 and ∼1200 yr younger dates for the ostrich eggshells. The strong discrepancy is here highlighted for the first time and we suggest that it may be linked with postdepositional phenomena in the vicinity of the artesian springs. A thorough review of 14C dates available for the Holocene in eastern Sahara shows that ostrich eggshells have been widely used. They seem slightly more prone to be discarded than other material but were never the object of a particular study in this context. Bayesian modeling shows that the Neolithic occupation at site KS043 spans a range from 5000 to 3950 cal BC (and concentrated around 4600–4350 cal BC). Characteristic flint tools and pottery relate this occupation to the end of the Neolithic and show links with the Tasian culture, confirming the timing of the presence of this cultural complex in the desert before its appearance in the Nile Valley.

Burial Grounds

This paper focuses on the chronology of Middle Bronze Age complexes in the Baraba forest steppe (western Siberia). Three sites were radiocarbon dated, Stary Tartas 4, Sopka 2, and Tartas 1. The Late Krotovo culture was dated to the 18–19th centuries BC, the Andronovo complex (Fedorovo stage) to the 15–18th centuries BC, and the Mixed Andronovo complex dated to the 15–17th centuries BC. These values are some 300–500 yr older than previously thought, and the new results are consistent with14C dates of the Andronovo cultural complex in northern Eurasia. Based on these data, the 15th century BC is the upper chronological limit of the Andronovo period.

Early Transcaucasian Culture

This article presents data on the Early Bronze Age of eastern Anatolia. During the period that for most scholars is recognized as the Early Bronze Age (ca. 3100–2100 BCE), eastern Anatolia was occupied by an intriguing cultural complex related to the Kura–Araxes culture, as it has been described by Kuftin after his excavations in Transcaucasia. This complex has alternatively been called “Karaz,” “Red Black Burnished,” or “Early Transcaucasian,” depending on the viewpoint adopted by successive scholars. Of all the labels used for describing the Early Bronze Age faciès of eastern Anatolia, the term Early Transcaucasian Culture seems to be the most appropriate, as it implies an organic relationship between East Anatolian cultural assemblages and Transcaucasia. Indeed, even if this issue is still a matter of debate, today most of the evidence points to a Transcaucasian origin for the east Anatolian Early Bronze Age.

Education Today

Business education epitomizes the cultural complex that situates performance (understood both as the intensification of valuation and as the spectacle of decision) at the center of social life. The experiential training technique known as the case method, famously recognizable as a Harvard Business School product, carries in particular a series of meanings that are central to the formation of the ideals of performance, adventure, effectiveness, and aplomb that distinguish business education today. It also conveys, however, elements of anxiety that are characteristic of the notion of the real that is actioned in such a setting. This hypothesis is explored here through an examination of early and contemporary aspects of the case method at the Harvard Business School, in particular in the financial valuation curriculum. It is suggested that the performative features of the case method, widely understood, concur with an exacerbation of the troubling aspects of the “performance complex.”
