In ancient China, as elsewhere, states did not simply occupy a given territory but actively engaged in the production of space by transforming landscapes, moving populations, and enacting territorial hierarchies, thus creating “state spaces,” to borrow a term coined by James C. Scott. In the case of the early Chinese empires of Qin (221–207 BCE) and Han (202 BCE–220 CE), state-induced migration and settlement were key instruments of military control, administrative incorporation, economic intensification, and other processes connected with spatial distribution of state power. This article combines insights from transmitted texts, excavated documents, and archaeological evidence to explore factors and effects of migration in early Chinese empires, discussing the interconnection between state-organized resettlement and private migration as well as their embeddedness in the local geography. As the situation varies according to location, the present article introduces the approach and tests it on a case study, the Guanzhong metropolitan region.

Population density is an important variable in the development of social complexity. Estimating population densities from the archaeological record requires combining estimates of population, area, and time. Archaeological population estimates tend to be reported as a maximum population derived from the total accumulation of discrete archaeological material types, usually ceramics or radiocarbon (14C) dates. However, given the palimpsest nature of the archaeological record at recurrently occupied archaeological sites, these maximal, total estimates are, at best, a poor reflection of contemporaneous populations. I present a method for calculating average yearly population densities for occupations at a large, multicomponent site using a combination of distributional data and 60 14C dates. By employing this method at other sites in the same region, modeling intra-regional population dynamics at fine time scales will be possible.

Recruitment is related to the occupation of the substrate by fouling organisms. It plays an important role in the maintenance and distribution of benthic populations, being under the influence of biotic and abiotic factors. In the present work, the recruitment of calcareous sponges was monitored over two years in a marina at Todos os Santos Bay, a large bay in the tropical portion of the Brazilian coast. Artificial plates were immersed, being replaced bimonthly and the potential influence of the seawater temperature, photoperiod and precipitation on the number of sponge recruits was tested. The results showed that the number of calcareous sponge recruits had significant temporal variation. Nevertheless, different species showed different patterns over time. Significant differences were observed for Sycon avus, Sycon sp. and Leucandra serrata, and the periods with the highest number of recruits were different amongst them. Sycon bellum, Paraleucilla incomposita, Leucilla sp. and Heteropia glomerosa did not show significant variation in the number of recruits over time. None of the three tested environmental factors were correlated with the number of recruits, but results indicated S. avus recruitment might be driven by seawater temperature. Our results contribute to improve the current knowledge on the dynamics of each species found on the plates and reinforce the general view that the pattern of recruitment varies greatly in Calcarea, even amongst sympatric species.

Large ground-dwelling Neotropical gamebirds are highly threatened by habitat loss and hunting, but conservationists rarely attempt to distinguish between these two threats in the management of populations. We used three different types of species records to determine the status (i.e. persistence level) of the Endangered red-billed curassow Crax blumenbachii in 14 forest remnants in north-east Brazil, as either persistent, precarious or extirpated. We related these persistence levels to variables measured in a 2-km buffer radius, including variables associated with habitat quality (proportion of forest cover, length of rivers, patch density, distance from rivers) and hunting pressure (proportion of cacao agroforests and farmlands, length of roads, total area occupied by settlements, distance from roads and from settlements). Curassows were more persistent in forest patches located (1) more distant from settlements, (2) in landscapes with few settlements, (3) in landscapes with a high incidence of roads, (4) in a mosaic with a high proportion of forest, shaded cacao agroforest and farmland, and (5) more distant from other forest patches. Hunting pressure potentially exerts more influence on persistence than habitat quality: (1) hunting pressure submodels had a higher explanatory power than habitat quality submodels, (2) final models comprised four hunting pressure variables but only two habitat quality variables, and (3) hunting pressure variables appeared in all models whereas habitat quality variables appeared in only one final model. If hunting pressure is driving declines in curassows, regions with low human presence and a high proportion of forest cover are recommended for establishing new reserves.

The flat oyster Ostrea edulis has declined significantly in European waters since the 1850s as a result of anthropogenic activity. Ostrea edulis was designated a UK Biodiversity Action Plan Species and Habitat in 1995, and as a Feature of Conservation Importance (FOCI) within the UK Marine & Coastal Access Act 2009. To promote the recovery of oyster beds, a greater understanding of its abundance and distribution is required. Distribution of O. edulis across the proposed Blackwater, Crouch, Roach and Colne MCZ in Essex was determined between 2008 and 2012. Ostrea edulis were present in four estuary zones; with highest sample abundance in the Blackwater and Ray Sand zones. Size structure of populations varied, with the Ray Sand and Colne zones showing a significant lack of individuals with shell height <39 mm. Ostrea edulis occurred in highest number on shell substratum, followed by silty sediments. There were no significant associations between O. edulis abundance or size structure with water column Chl a, suspended solids, oxygen, nitrate or ammonium concentrations, temperature or pH. Highest abundance and most equitable population shell-size distribution for O. edulis were located within, or adjacent to, actively managed aquaculture zones. This suggests that traditional seabed management contributed to the maintenance or recovery of the species of conservation concern. Demonstration that the Essex estuaries were a stronghold for Ostrea edulis in the southern North sea area led to the designation of the Blackwater, Crouch, Roach and Colne estuaries Marine Conservation Zone in 2013.

This paper attempts to resituate the Irish so-called ‘Royal’ sites within our vision of the Iron Age by challenging current understanding of their function as primarily situated in a ceremonial or ritual realm. While the evidence from these sites speaks to the complexity of their function, conceptualisation, and symbolic relevance, it is argued here that they are integral focal points of settled landscapes. Their architecture is suggested to address very specific concerns of the agrarian communities that built them and, in its very distinct change over the course of the Iron Age, to reflect broader societal developments, namely the emergence and decline of new society formations. Artefacts and ecofacts, architecture and landscape context of these sites contain a wealth of information on the activities that were taking place on and near them. It is argued that, freed from a binary ritual/profane interpretational framework, this evidence becomes readable as a record of Iron Age society and its dramatic changes over time.

The Canterbury Hinterland Project (CHP) has combined aerial photographic and LiDAR analysis, synthesis of HER and other data across east Kent with targeted survey south and east of Canterbury. We present possible hillforts, temples, large enclosures, a major trackway, linking paths, burials and high-status Roman-period complexes and argue that people organised the landscape to communicate meaning in two main ways: a ‘public’ face oriented towards the Dover–Canterbury road and expressions of ritual and remembrance for local groups. The character of this rural population has traditionally been understood in terms of its relationship to the civitas capital and villas; we look beyond this to examine a more detailed vision of possible social interactions.

The paper presents radiocarbon (14C) dates of samples collected from the Bronze Age cultural strata (VI–II) excavated within Sector P, Tell Arbid, Khabur Triangle, northern Mesopotamia. These strata contain objects (remains of a caravanserai, pits, graves, pottery kilns, and multi-phase houses) representing the periods of Early Jezirah 4-5, and Old Jezirah I-II. 14C dating of these strata was especially important because of a clearly visible period of abandonment of the area at the onset of 2nd millennium BC, recorded on all Khabur Triangle sites studied so far, and because of the questionable reliability of the chronology derived from scarce historical sources. Of the 29 samples of cereal grains, 9 appeared to contain residual material, while Bayesian-analyzed 14C ages of the remaining 20 allowed us to say that, at the turn of the 3rd millennium BC, Tell Arbid was abandoned later than other sites in the area, and that it was occupied over a distinctly longer period during the early 2nd millennium.

Recent archaeological survey and excavation in China have demonstrated that large sites of the late fourth and third millennia BC were situated not on the Central Plains—where the later dynastic centres were located—but along the Yangtze and lower Yellow River Basins. Their decline in the late third and second millennia BC coincided with the growth of sites to the north of the Central Plains. Evidence for settlement size and a new chronology constructed from radiocarbon dates emphasise discontinuities in the geographic distribution of settlements, combined with continuity in cultural practices of ritual feasts and the use of symbolic jades.

Since 1967, despite international legal restrictions, Israel has sought to annex Eastern Jerusalem. Fifty-one years later, it publicly declared in its Nation State Law: “Jerusalem, complete and united, is the capital of Israel.” In the West Bank, Israel initiated on the ground changes that furthered annexation without formally declaring any part of it as annexed. For decades, Al-Haq has documented the gradual encroachment of occupation by successive Israeli administrations. And yet the Palestinian leadership failed to successfully utilize the law to support its case. Nor could the 190 states, parties to the Fourth Geneva Convention, be convinced to enforce the provision in the Convention which bids the High Contracting Parties to “ensure respect for the present convention in all circumstances.” During the Oslo negotiations, Israel succeeded in leaving Jerusalem and the Jewish settlements outside of the jurisdiction of the Palestinian Authority. Given these patterns across nearly a half-century of history, it seems likely that Israel will declare the full annexation of the West Bank in part or in its entirety precisely because it has succeeded in accomplishing this in the case of Jerusalem.

Pingelap Atoll, 1.8 km2 in area and nearly 70 km from the nearest island, presents a clear example of anthropogenic niche-building in physically isolated circumstances with limited resources. This paper presents the first radiocarbon (14C) dates (n=8) from an archaeological project examining settlement and subsistence practices on the atoll, specifically how Pingelapese people have constructed the environment to meet their needs over centuries of occupation. These dates confirm that human occupation of Pingelap occurred by 1700–1550 cal BP (2σ) at the latest, only a few centuries after the earliest securely-dated settlement of high islands in the region (Kosrae and Pohnpei), and with strikingly similar timing to another atoll in the region, Mwoakilloa. Evidence of early settlement includes shell tools, ornaments, extensive marine faunal remains, and charred botanical domesticates. These preliminary data build a framework for the settlement history and environment building of Pingelap.

We draw on uniquely detailed micro-level data from a Belgian professional medical liability insurer to examine how different procedural and legal events that take place during the unfolding of a medical malpractice claim influence the timing of its settlement. Utilizing the competing risks regression framework, we find that settlement hazard is all else equal statistically significantly positively associated with the completion of those procedural and legal events that most effectively reveal factual information about the underlying medical malpractice case. Consistent with theory, settlement hazard is either unassociated or even negatively associated with the completion of other procedural and legal events. Our analysis, therefore, provides policy insights into which aspects of the resolution process could be emphasized, and which de-emphasized, in order to reduce the often excessive duration of medical malpractice claims and its adverse effects on the healthcare system.
