Characterising the late prehistoric, ‘Romano-British’ and medieval landscape, and dating the emergence of a regionally distinct agricultural system in South West Britain

Palaeoenvironmental evidence for the character of lowland cultural landscapes during the last 2500 years in Britain is poorly understood, owing to a combination of an over-reliance on data from upland sequences, and because lowland mires are typically located in positions marginal to areas of settlement and agriculture. This paper presents an attempt to derive environmental evidence for this time period from a lowland context in order to characterise the key periods of change and continuity in the lowlands. The study focuses on mid-Devon, in South West Britain, and uses small pollen sites which are embedded within the historic landscape. The South West is a particularly poor region for lowland environmental data, and has until now been reliant on upland sequences. The results show that continuity, rather than abrupt change, has characterised the landscape from the later Iron Age to the early medieval period (around cal AD 800). There is no palynologically distinct Roman period in the data, contrary to evidence from the high uplands of Exmoor that suggests a decline of the agricultural system during the immediate post-Roman period. Around cal AD 800 there is a change in the agricultural system from predominantly pastoral activities to one that led to relatively high proportions of cereal pollen appearing in the sequences, which is interpreted here as marking the onset of convertible husbandry, a regionally distinct agricultural system which is recorded from AD 1350, but whose origins are not documented. This agricultural system remained in place until the post-medieval period, when the predominant agricultural regime returned to pastoralism around AD 1750. The data clearly show discrepancies between the high uplands and the lowlands, demonstrating the potential hazards of extrapolating upland sequences to lowlands environments.     

The Behavioral Impact of Drinking and Driving Laws

All U.S. states have laws designed to discourage people from drinking and driving, but enforcement varies across the states. Existing studies offer conflicting evidence on the effectiveness of these strategies in deterring drinking‐and‐driving behavior. Deterrence theories imply that the mere existence of such laws has little impact on criminal behavior, but the perception of enforcement and the probability of being detected have a deterrent effect. To test these hypotheses, we develop a measure of the propensity to drink and drive using item response theory and national survey data. Inferential models test the impact of perceptions of enforcement, actual enforcement levels, and deterrence laws on criminal propensity. Results indicate that the existence of statutes impacts only those least likely to drink and drive, while perceptions of the likelihood of arrest and individual agreement with the goals of drinking and driving laws significantly reduce the propensity for almost everyone. Actual enforcement rates display no behavioral effect.     

La Découverte de L’Amérique

This article examines the significance accorded to the discovery of America in the period between 1492 and the publication of Alexander von Humboldt’s Kosmos in 1855. It argues that, the « discovery » of America was perceived as the « uncovering » of not merely a place, but of an epistemological challenge which both transformed, Europe’s intellectual dependence on Antiquity, and shaped its evolving perception of both space and time. It argues that, after the discovery, human history came to be seen, in terms of as series of inventions all of them related to human movement, which were projected, as more and more of the globe was « discovered » into an unpredictable future.     

Charity and Justice in Global Poverty Relief

Peter Singer's message in One World: The Ethics of Globalisation is that we must now consider the whole of the world and all of its peoples our home. The penultimate chapter ‘One Community’ argues that there are no good reasons why those individuals who have the means should not donate to organisations that address the problems of global poverty relief. This, however, is not an adequate ethic; it does not provide the foundation we need in order to construct a sustainably just world order. Singer's recommendations may well lead to the construction of a world in which there is a significant reduction in the level of global poverty. However, Singer's route to poverty reduction is via charity, not justice. Global justice is not the same as individualist practical ethics, even if the latter is applied on a global scale. Singer's concerns for long-term global poverty relief will be better served by an agenda that promotes global institutional change, rather than one that is limited to hoping against donation fatigue among the world's affluent.     

Modeling ground slate knife production and implications for the study of household labor contributions to salmon fishing on the Pacific Northwest Coast

Despite longstanding anthropological concerns with the origins of intensive delayed-return subsistence economies and the timing of the development of increasingly complex political systems on the Northwest Coast, the use and production of slate knives—one of the most archaeologically visible tools used to process seasonally available salmon—has received little attention in the archaeological literature. This can be attributed, in part, to the persistence of artifact typologies that have failed to generate behavioral implications for variability in slate artifact assemblages. In this article, I use data derived from ethnographic, experimental, and actualistic research to develop an approach to the classification of slate artifacts expected of knife-production activities. Emphasis is placed on framing slate knife production as a temporally emergent and situated activity, but also as an operational sequence that can be modeled due to regularity in the decisions and motions expected of tool makers producing functionally specific tools. Using slate assemblages recovered during the partial excavation of seven Late and Contact period Coast Salish houses in southern British Columbia, I then evaluate and demonstrate the utility of this approach by considering variability in household labor contributions to salmon fishing.     

Heterogeneous impacts of China's economic and development zone program

This paper examines the impact of economic and development zones (EDZs) on the productivity of incumbent firms in China. To deal with the selection issue, I first take into account potentially different selection mechanisms across two popular types of EDZs—economic and technological development zones (ETDZs) and high‐tech development zones (HTDZs)—by relying on multiple treatment propensity scores matching techniques. Next, I apply the difference‐in‐differences estimator to the matched sample and conduct an event study analysis. The results show that the respective effects of ETDZs and HTDZs on firm productivity are positive, but subject to a nonlinear trend over time. The size of the productivity gains depends critically on the type of EDZ, however. A new HTDZ (ETDZ) leads to an average productivity gain of up to 30.2% (18.4%) for incumbent firms in the 5 years after the zone was created. These findings suggest that the size of productivity spillovers for spatially targeted firms differ quite significantly depending on the strategic development and policy goals of the EDZ: HTDZs that focus on promoting indigenous‐based factors of learning lead to higher productivity spillovers compared with ETDZs that focus on promoting extra‐local linkages.     

Biblical beliefs in the shaping of modern nations

The ideology and culture of modern nations and nationalism have been profoundly influenced by two traditions that reach back into the ancient world, the biblical and the classical. Here, the focus is on the particular contribution of the Hebrew Bible to the political ideals of modern nationhood. Modern Western nations, unlike non‐Western and ancient nations, are distinguished by their quest for territorial integrity and sovereignty, citizenship, legal standardisation, cultural homogeneity and secular education, while modern nationalism is a pro‐active, ideological movement that seeks to ‘build’ autonomous, unified, distinctive and ‘authentic’ nations out of ethnic populations deemed by some members to constitute actual or potential ‘nations’. While modern European nations emerged out of the matrix of Christianity, as Adrian Hastings argued, it was the political model and ideals of community found in the Hebrew Bible, which Christianity adopted (while rejecting the Jews) and which the New Testament lacked, that so often provided the dynamic of modern nationalism and the values of modern Western nations. Chief among these were the Pentateuchal and prophetic narratives of Exodus, Covenant, Community of Law (Torah), the holiness of a ‘chosen people’, the messianic role of sacred kingship and the dream of fulfilment in the Promised Land. These ideals did not fully come into their own until the Reformation. In this period, state elites expressed growing national sentiments and biblical texts were being rendered into the vernacular, while a more rigorous biblical form of ‘covenantal nationalism’ emerged in early modern Netherlands, Scotland and England, taking the narrative of the deliverance of the Israelites as its starting point. In the eighteenth‐century Enlightenment, the novel cults of ‘Nature’, ‘Authenticity’ and ‘Human Perfectibility’ secured an opening for neo‐classical political ideas in the formation of nations. But it was the biblical ideals of liberation, Covenant, election and promised land that provided the basic model of the modern nation and nationalism in Europe, from the French Revolution, and German and East European nationalisms to the Hebraic Protestant nationalism of Victorian Britain. To a large extent, the modern age owes to the Jewish Bible its fundamental vision of a world divided into distinctive and sovereign territorial nations.     

Picking 'winners' in space: Impact of spatial targeting on firm performance in China

This paper examines the spatial patterns of China's industrial encouragement policy and its distributional impact on firm productivity. To this end, I develop separate proxies to measure three popular policy instruments (subsidies, tax holidays, and preferential access to loans). I first show that China's industrial support policies tend to exhibit a prominent spatial feature of targeting firms located in lagging cities with lower density. Taking into account potential endogeneity of industrial policy, unobserved heterogeneity and firm dynamics, quantile regression techniques show that more intense industrial support leads to: (a) a reduction in the productivity of lower-performing firms, especially in denser cities; and (b) a small productivity gain for better performing firms but only in denser cities. Counterfactual analysis further reveals that pursuing an alternative, space-neutral industrial encouragement policy would increase average productivity by 14–16%, in aggregate, but also contribute to significantly higher regional inequality.     

US grand strategy and national security: the dilemmas of primacy,decline and denial

The foreign policy crises that the USA has confronted under the administration of President Barack Obama have generated profound uncertainty about whether the USA can maintain what has been its consistent grand strategy since the end of the Cold War: primacy. The authors argue, drawing on a neoclassical realist framework, that this uncertainty has been driven not so much by fundamental changes in the international system itself, but rather by how such changes have been interpreted by the Obama administration and its critics. US grand strategy is now caught between approaches best described as the ‘decline management’ of the Obama administration and the ‘decline denial’ of president Donald Trump, which reflects the fracturing of the domestic ‘political support system’ that has underpinned primacy since the end of the Cold War.
