Coast–inland mobility and diet in the Danish Mesolithic and Neolithic: evidence from stable isotope values of humans and dogs

Here we present the stable isotope ratios of carbon and nitrogen measured in bone collagen extracted from humans, dogs, herbivores and fish from Mesolithic and Neolithic coastal and inland sites in Denmark. Bones of freshwater fish from several Early Mesolithic lake-side sites have δ¹³C values surprisingly similar to those seen in marine fish. We propose a model, based on δ¹³C and δ¹⁵N, for the correction for both marine and hard water reservoir effect in radiocarbon dates. A strong reliance on aquatic protein is demonstrated for the Mesolithic inhabitants of the region from the middle of the Early Mesolithic onwards. A significant part of the protein in the diets of the dogs and humans from the Middle and Late Mesolithic was of marine origin, even at inland sites. This observation points to a high degree of (seasonal) coast-inland mobility. The isotopic evidence indicates that during the Neolithic small quantities of aquatic foods were still common sources of dietary protein.     

The Waikato River: Changing Properties of a Living Māori Ancestor

In Māori cosmology, rivers and other waterways are conceptualised as living ancestors, who have their own life force and spiritual strength. The special status of rivers in Māori society also explains why they are sometimes separated from other Māori claims to natural resources of which they were dispossessed in the 19th century. Until recently, Māori were often eager to contend that ownership of rivers is not their prime interest, but instead, they argued that they feel obliged and responsible to keep rivers fresh, clean, and flowing. This perspective, however, changed under the impact of a new government policy of selling shares in energy corporations that use freshwater and geothermal resources for energy production. In this paper, I provide an ethnohistorical account of the Waikato River and show how conceptions of this ‘ancestral river’ changed in the course of colonial and postcolonial history, more specifically in response to a recent shift in government policy. In 2008, a joint management agreement was signed between the government and Waikato Māori for a ‘clean and healthy river’, leaving the issue of ‘ownership’ undecided. Only two years later, however, Māori felt forced to claim ownership when the government moved to sell shares of power‐generating energy companies located along the river, which effectively transformed their ‘ancestor’ into a property object.     

Platform Capitalism’s Hidden Abode: Producing Data Assets in the Gig Economy

In this article, we argue that the governance of gig work under conditions of financialised platform capitalism is characterised by a process that we call “dual value production”: the monetary value produced by the service provided is augmented by the use and speculative value of the data produced before, during, and after service provision. App-governed gig workers hence function as pivotal conduits in software systems that produce digital data as a particular asset class. We reflect on the production of data assets and the unequal distribution of opportunities for their valorisation, after which we survey a number of strategies seeking data-centric worker empowerment. These strategies, we argue, are crucial attempts to push back against platform capitalism’s domination, bankrolled by what we term “meta-platforms”. Ultimately, it is the massive wealth and synergetic capacities of meta-platforms that constitute the most formidable obstacle to worker power and social justice in increasingly data-driven societies.     

The Role of Engineer-in-Chief and the Introduction of Foreign Hydraulic Dredging Technology and River Conservancy into China, 1890s–1930s

This paper discusses studies of the development of river conservancy in modern China, and the role of engineers-in-chief in river improvement planning on rivers such as the Hai-ho (Haihe) and the Whangpoo (Huangpu). It discusses the introduction of foreign hydraulic dredging technology and management into two major Chinese ports. It then analyses the process by which two agencies of the Chinese government absorbed and adjusted this technology to suit local circumstances in the treaty ports of Tianjin and Shanghai beginning in the 1890s. Without prior experience in river conservancy, the conservancy boards adopted a range of foreign technologies. This allowed them to develop into major institutions that facilitated increasing trade flows between China and the rest of the world. Of particular significance in this process of technological change was the role of the expatriate engineers-in-chief who were employed as chief executive officers of both agencies. They were responsible for establishing the operations of the agencies, accommodating an increasing range of responsibilities such as financial and human resource management, and training Chinese engineers and managers for senior positions until they were ready to replace the expatriate engineers-in-chief after the 1930s.     

Making Sense of the Scottish Community Energy Sector – An Organising Typology

The community energy sector is widely understood to be a pluralistic sector, encompassing a broad range of aims, motivations, and practices. This heterogeneity is, however, still not very well understood. Dominant analytical frameworks in the study of energy geographies offer little in the way of exploring the diversity of motivations, visions, and social relations that are present within the community energy sector, nor their causes or consequences. Drawing on the notion of ‘critical pluralism’, this paper aims to highlight the diverse range of sociotechnical configurations that make up this sector in Scotland, and begins to discuss some potential causes and consequences. To do so, it presents a novel community energy typology, based on an analysis of technical and social dimensions of 367 projects in Scotland. This shows that whilst the Scottish community energy sector contains a broad range of motivations, technologies, and social practices, the sector has become dominated by groups for whom energy generation is a means to achieve local socio-economic development. The paper discusses the community-level and policy drivers that may have contributed to this. It also discusses how we can begin to understand a diverse sector’s ability to affect the wider structures in which it operates.     

Prehistoric Ceremonial Warfare: Beginning of Institutionalized Violence

Sadly, aggression is still one of the most common features of human behaviour; it is an instinct to promote and survive our own genes against the genes of others. Human intraspecific aggression has gradually become part of human culture over the last 40,000 years and has been institutionalized in various forms of social activities. Particularly in the post-glacial period, the level of social relations has developed dramatically in the context of population growth and the growth of human communities. In the time of Neolithic and Chalcolithic European agricultural populations, the motive of control over farming land became highly important. Also the control of main means of production and social power was increasingly maintaining the intragroup competition and aggression. Thus, violence was employed within the community in order to obtain and maintain individual or collective social status, but also against other communities in an effort to protect property and territory. Particularly the intracommunity aggression was soon transformed into variety of different formal ways of symbolic fighting, which usually did not lead to the unwanted death of a defeated member of the community. The symbolic struggle between members of the community as well as the defense against external aggression were gradually formalized in the form of introduction of specialized weapons designed for combat between people and creation of fortifications. During the Neolithic period a new phenomenon arose in human culture: warfare.
