We experimentally created a particle size dataset that is based on reduction sequences and raw materials typical of the Middle and Later Stone Age in southern Africa. The reason for creating this new dataset is that current particle size frameworks are based, almost exclusively, on flint and western European knapping methods. We produced the dataset using knapping methods and raw materials frequently encountered in the southern African archaeological record because we wanted to test whether it has the same distribution as particle size datasets experimentally created in Europe, and to initialise the production of a database for use in the analysis of lithic assemblages from southern African Late Pleistocene deposits. We reduced 117 cores of quartz, quartzite, jasper, chalcedony, hornfels, and rhyolite. The knapping methods selected were unidirectional, discoidal, Levallois recurrent and bipolar flaking. In this article we compare this new particle size distribution dataset with the results obtained from previous experiments. We found that the southern African dataset shows a wider size range distribution, which seems to be explained by differences in knapping methods and raw materials. Our results show that there is overlap between the distribution of the southern African experimental knapping dataset and the sorting experiment conducted by Lenoble on flint artefacts in a runoff context. This article shows that a particle size analysis is not sufficient on its own to assess the perturbation of an archaeological assemblage and must be coupled with other analytical tools.

This article examines the meaning and function of the Old English noun reaflac in two tenth‐century lawsuit documents, Sawyer 877 and Sawyer 1211. It suggests that reaflac was the vernacular counterpart to the Latin terms violentia and rapina. Such connected terminology suggests that a collection of now lost tenth‐century Old English charters, like S 877 and S 1211 in form, was the original source for the twelfth‐century Ely house chronicle, the Libellus Æthelwoldi. Charter draftsmen purposefully selected a language of violence in order to delegitimize a rival party’s claim to an estate, regardless of whether any acts of violence had taken place. Reaflac formed part of this narrative strategy in early English lawsuit documents because of its association with contemporary discourses on moralized wrongdoing.

This essay presents a survey of recent work in the history of international and global health from the mid-nineteenth to the early twenty-first centuries. It considers longstanding narratives alongside recent studies that have deployed approaches consonant with scholarship in the emerging global history of science and medicine. The cumulative impact of this work is to show how the history of international health has long been embedded in colonial landscapes of power, even as it also fostered revolutionary nationalism and grew from anti-colonial socialist internationalism; and how the absence, as well as presence, of intervention has shaped understandings of global health in recent decades.

This article examines the significant relationship that existed between commercial British television and the study of animal behaviour. Ethological research provided important content for the new television channel, at the same time as that coverage played a substantial role in creating a new research specialism, the study of primate facial expressions, for this emergent scientific discipline. The key site in this was a television and film unit at London Zoo administered by the Zoological Society and Granada TV. The Granada unit produced 'Animal expressions', a twenty-five-minute television film based on research on monkeys and apes by the Dutch postgraduate student and soon-to-be-leading-authority Jan van Hooff. Recovering the production and multiple uses of 'Animal expressions', this paper offers the first sustained historical analysis of science on commercial television. I show how Granada patronage helped Van Hooff to support his argument that human expressions such as smiling and laughter shared common evolutionary origins with similar facial movements in nonhuman primates. Emphasizing the mutual shaping of science and ITV, I argue that 'Animal expressions' repurposed televisual conventions of framing talking heads, and blended serious science with the comedy of 'funny faces', thereby epitomizing Granada's public-service strategy at a time when commercial television was defending itself from criticism in the Pilkington report.

The escheator was an important royal official who, by the fifteenth century, had accumulated a wide range of responsibilities. Escheators were accountable to the exchequer, and each official was responsible for ‘escheats’ arising to the crown within a county or pair of counties, called an ‘escheatry’. One of the escheator’s roles was to account for goods and chattels forfeited to the crown by felons, fugitives and outlaws: people who had been convicted or indicted of felonies (including suicides); who had fled following an accusation of felony; or who had been outlawed following repeated failure to appear in court to answer a charge of felony, or to respond to a civil suit.

This article offers some reflections on the importance Adam Smith accorded to luck in The Wealth of Nations. While the place of moral luck in The Theory of Moral Sentiments has been the subject of some scholarly attention, this has not been the case for luck in his best-known work. It focuses on what Smith thought particularly striking about our estimation of our own good fortune and argues that it accentuated the need for trustworthiness and trusted friends.

This article calls into question a story that has become part of the folklore and indeed the official history of Cambridge University. Supposedly, the passage of the Chantries Act posed a threat to university colleges which was averted by the lobbying of Cambridge academics early in 1546, and this adroit intervention inspired Henry VIII to found new colleges at Oxford and Cambridge. Close reading of the sources, however, indicates that the universities were singled out for special treatment from the start and that Henry's new foundations were in his mind before the Chantries Act was passed.

This article brings together some of the improvements to GDP estimates from the income side since the publication of Charles Feinstein's 1972 volume National income, expenditure and output of the United Kingdom, 1855–1965. Many of the improvements and refinements were made by Feinstein himself and this paper makes a start in bringing the different elements together, focusing chiefly on reconstructing the income‐based estimates for the period 1841–1920. The new data are then used to comment on several features of the late nineteenth‐century UK economy, considering both the trend and cyclical path of the economy. The new data, coupled with modern de‐trending methods, suggest that there was a long‐term slowing of the UK economy from the late nineteenth century, starting from the 1870s. To undertake the trend–cycle decomposition, we employ a wavelets methodology to describe the time–varying features of trends and cycles over this period.

The classic work on the morphology of limestone calcite cements done in the 1960s is extended here by utilising growth zones to reconstruct the growth of cement crystals. Only cement composed of fitted polyhedral monocrystals that form by passive crystallisation of calcite on the walls of liquid‐filled, static pores and fissures is considered. Cement can either be initiated by (1) nucleation, when new crystals start but are not attached to their substrate, or (2) seeding, when new crystals are seamlessly connected to and influenced by substrate crystals. After seeding, epitaxial cement growth starts with many sub‐crystals that coalesce distally, followed by layered mantle growth. Junctions between three intercrystalline boundaries in cement aggregates with one interfacial angel = 180° are of two types: the first, enfacial junctions are caused by a pause in the growth of one crystal and the second is caused by movement of all boundaries due to dissolution of adjacent calcite. Growth zone offsetting at some intercrystalline boundaries is caused by dissolution of calcite at boundaries when permeability values are low. The same width to height ratio of mature aggregate crystals is predicted from the shape of the crystal's growth surfaces; dogtooth calcite forms columnar and nail‐head calcite forms tabular‐shaped crystals. Seeding on different sized crystals causes variations in epitaxial growth rate with faster growth on large crystals resulting in a disorganised cement fabric; the variation in epitaxial growth rate is perpetuated into mantle growth. Echinoderm syntaxial crystals dominate many pore cements due to the large size of their seed ossicles, at the same time, syntaxial crystals form on relatively tiny seeds. Texturally mature crystal aggregates with isopachous fabric are initiated from three different substrate to cement arrangements. Calcite cement zones preserve their original positions allowing the investigation of cement's growth and chemical history.

Spatial analysis is paramount for understanding, monitoring, and conserving ancient settlements and cultural landscapes. Advancing remote sensing and prospection techniques are expanding the methodological frame of archaeological settlement analysis by enabling remote, landscape‐scale approaches to mapping and investigation. Whilst particularly effective in arid lands and areas with sparse or open ground cover, such as vegetation and buildings, these approaches remain peripheral in tropical environments because of technical and contextual challenges. In tropical Eastern Africa, for example, scales, resolution and visibility are often compromised by thick vegetation cover, inadequate access to, if not lack of, imagery resources and technologies, and the availability of comparative archaeological data for interpretation. This paper presents the initial results of spatial analysis, using historic landscape characterisation, remote sensing, published and legacy data, and a pilot ground survey to examine the earliest settlement of Zanzibar, Unguja Ukuu. Comparing multiple strands of evidence in a Geographic Information System (GIS), we use each as a test on the others to draw out the strengths and weaknesses of each technique in the context of tropical and coastal Eastern Africa. Drone photogrammetry, geophysical prospection, and ground survey were compared with legacy remote sensing resources and the results of a coring survey conducted across the site during the 1990s into a GIS platform to produce multi‐phase hypothetical maps of the archaeological site in the context of its potential resource landscape. These were then tested against the results of recent excavations. The discussion highlights the challenges and potential of combining these techniques in the context of Eastern Africa and provides some suggested methods for doing so. We show that remote sensing techniques give an insight into current landscapes but are less useful in understanding or modelling how sites would have fitted into their surroundings in the past, when conditions were potentially very different.
