Faecal biomarker and archaeobotanical analyses of sediments from a public latrine shed new light on ruralisation in Sagalassos, Turkey

A public latrine in the ‘Imperial Baths’ of Sagalassos was transformed into a dump site in the early Byzantine period. Several layers of urban waste, including ceramics, bones, glass and perhaps excrements were deposited on the floor. Faecal biomarker analyses and archaeobotanical analyses were conducted to reconstruct the history of the room. 5β-stanols of human origin, such as coprostanol, were found in the sewage channels together with mineralised plant remains, indicating a human faecal context. The botanical remains are furthermore representative of the Roman diet of the Sagalassians. Soil layers, deposited on top of the latrine floor and dating to the early Byzantine period, contained herbivore derived 5β-stanols, such as 5β-stigmastanol and epi-5β-stigmastanol. Additionally, a clear predominance of epi-5β-stanols over 5β-stanols showed that the animal dung has been subject to composting. In this period, the former latrine was clearly used as a manure production site which is further confirmed by stratigraphic evidence of large amounts of urban waste artefacts, which were commonly collected together with manure before application on the fields. The results of the present study support the theory that off-site potsherd scattering can be used as a proxy for manuring events. Additionally, the data show key evidence for vertical migration of 5β-stanols and presumably also for the leaching of bile acids.     

Ammonite dating of latest Cretaceous mosasaurid reptiles (Squamata,Mosasauroidea) from Jordan—preliminary observations

Jagt, J.W.M., Jagt-Yazykova, E.A., Kaddumi, H.F. & Lindgren, J., April 2017. Ammonite dating of latest Cretaceous mosasaurid reptiles (Squamata, Mosasauroidea) from Jordan—preliminary observations. Alcheringa 42, 587-596. ISSN 0311-5518

Newly collected ammonoid material from the uppermost Cretaceous portion of the Muwaqqar Chalk Marl Formation exposed some 30 km southeast of the Qasr Al’Harrana area (east-central Jordan) includes medium-sized baculitids (Baculites ovatus auctorum, non Say), the sphenodiscid Libycoceras acutodorsatus (Noetling) and the pachydiscids Menuites fresvillensis (Seunes) and Pachydiscus (Pachydiscus) dossantosi (Maury). Of the two last named taxa, the former is a good marker species for the upper Maastrichtian, with records from Europe, central Chile, South India, Baluchistan (Pakistan), Australia, Madagascar and South Africa. The latter is known from the United Arab Emirates/Oman border area, from strata of (late) early to early late Maastrichtian age, as well as from more poorly constrained Maastrichtian levels in Brazil and Nigeria. A comparison with ammonoid assemblages from the Maastrichtian type area (southeast Netherlands/northeast Belgium) suggests correlation of the Muwaqqar Chalk Marl Formation with the middle/upper Maastricht Formation (Emael and Nekum members, ca 66.5–66.1 Ma) and the upper part of the coeval Kunrade Formation. However, associated ‘tegulated’ inoceramids of the Tenuipteria argentea group from the Muwaqqar Chalk Marl Formation favour equivalence with a higher level of the Maastrichtian type area, i.e., the Meerssen Member. From the upper Maastricht Formation and the equivalent upper part of the Kunrade Formation, the following mosasaur genera are currently known: Mosasaurus, Prognathodon, Plioplatecarpus and Carinodens. Interestingly, coeval strata of the Muwaqqar Chalk Marl Formation in east-central Jordan have yielded remains of a largely comparable suite comprising Prognathodon, Mosasaurus, Carinodens and an unnamed, highly derived plioplatecarpine.

A history of failed innovation: continuous cooking and the Soviet pulp industry, 1940s–1960s

Abstract

In the years before and after the Second World War, chemical and related industries in a variety of countries experienced a surge in innovation and development. As a result, the pulp industry became a space for considerable innovation. In Sweden, Johan Richter developed the Kamyr digester, a pulp cooker that could run continuously and was adopted by industry within a decade. Prior to Richter, Soviet engineer Leonid Zherebov designed a similar cooker. But after 25 years of experiments, Zherebov’s design failed, and Soviet factories began to produce pulp using imported Kamyr digesters. This article examines the history of continuous pulp cooking in the Soviet Union as a means to understand the nature of Russian technological innovation and its failures. The paper contends that his effort failed because of the technological system developed by Soviet forestry – a system characterized by a lack of open communication among its main institutional actors and a scarcity of resources to facilitate innovation.     

‘A Shop Window Where You Can Choose the Goods You Like’

This article examines the Finnish industrial and trade fairs held in the Soviet Union in the context of Finnish–Soviet trade and scientific–technical cooperation in the 1950s and 1960s. While primarily focused on fairs, it also discusses different activities that accompanied them, such as lectures, visits, and negotiations between Finnish traders and Soviet officials and specialists. This study illustrates how such first-hand contact played an important role in Finnish–Soviet communications. First, they helped Finnish producers showcase their goods and technologies directly to Soviet buyers in various ministries and organizations. Second, these contacts included diverse activities such as face-to-face contacts, lectures, and seminars, being a means of technology transfer from Finland to the USSR . Finally, although they were commercial interactions without explicit ideological purposes – like many international exhibitions of the last century – Finnish fairs demonstrated a technological gap between Finland and the USSR.     

Rock Art Between Preservation,Research and Sustainable Development—a Perspective from Southern Ethiopia

This paper focuses on southern Ethiopia, along the outer rim of the Rift Valley and not far from the Kenyan border, in an area forming part of a larger region known as a cradle of humankind. However, it also hosts a diverse Holocene rock art heritage, which is still underestimated and underdocumented. Paintings and engravings are widespread in the region, both in rock shelters and open-air sites, often located in remote areas currently inhabited by communities belonging to different ethnic groups. The aim of this paper is to present the first results of a new project in the area around Yabelo, within the broader framework of rock art research in East Africa, integrating archaeological research, preservation and heritage management with a relevant involvement of local communities. The outstanding cultural importance of these contexts offers new prospects for both scholarly research and sustainable development. The recording and study of the artworks is underway, using digital technologies that guarantee a high standard of accuracy of the documentation and non-invasive recording methods. This provides important insights for reconstructing cultural dynamics in the area between the final Pleistocene and onset of the Holocene. Moreover, the focus on rock art makes it possible to enhance local knowledge, increasing the awareness of local communities, with a significant impact on the preservation of this fragile heritage and the development of local, sustainable tourism projects. Differently from other archaeological features, rock art can have a more immediate attractiveness for contemporary observers, in terms of the apparent immediacy of the images and their emotional impact, raising awareness of cultural heritage and fostering major involvement in its preservation.     

CAN A PREDICTED FUTURE STILL BE AN OPEN FUTURE? ALGORITHMIC FORECASTS AND ACTIONABILITY IN PRECISION MEDICINE*

The openness of the future is rightly considered one of the qualifying aspects of the temporality of modern society. The open future, which does not yet exist in the present, implies radical unpredictability. This article discusses how, in the last few centuries, the resulting uncertainty has been managed with probabilistic tools that compute present information about the future in a controlled way. The probabilistic approach has always been plagued by three fundamental problems: performativity, the need for individualization, and the opacity of predictions. We contrast this approach with recent forms of algorithmic forecasting, which seem to turn these problems into resources and produce an innovative form of prediction. But can a predicted future still be an open future? We explore this specific contemporary modality of historical futures by examining the recent debate about the notion of actionability in precision medicine, which focuses on a form of individualized prediction that enables direct intervention in the future it predicts.     

A case of Madelung's deformity in a skeleton from Nuragic Sardinia

The case reported here refers to the skeletal remains of a mature adult male found in a collective grave known as ‘Giant's tomb’ located near Donori (Sardinia) and dating to the end of the Bronze Age. The skeleton showed bilateral shortening of the forearm associated to radial bowing, marked deformations at the radio‐ulnar distal joints and subsequent posterior dislocation of both ulnae. The whole alterations fit well with a diagnosis of Madelung's deformity, a rare form of mesomelic dysplasia. At present, this case is the most ancient evidence of Madelung's deformity.
