A Covering Tour Model for Planning Mobile Health Care Facilities in SuhumDistrict, Ghama

The provision of adequate primary health care in developing countries is often troublesome. The problem is to provide a sufficient number of facilities to be geographically accessible, yet few enough to be properly stocked and staffed. In many less developed countries accessibility problems are exacerbated by extensive rainy seasons in which travel is only possible on paved roads. Using the covering tour model we investigate the use of mobile facilities to resolve this dilemma in Suhum District, Ghana. The model minimizes a mobile facility's travel while serving all population centers within range of a feasible stop. Computational results show that in the rainy season the model cannot provide full coverage; over six percent of the population is beyond a covering distance of eight kilometers. In the dry season, 99 percent of the population can be served by a tour at a covering distance of seven kilometers.Beyond a distance of four kilometers, the dry season problem becomes a trade-off between the distance traveled by healthcare patrons and mobile facilities. These results illustrate the importance of flexibility of mobile systems: if accessibility cannot be provided in all seasons it may still be provided at favorable times of the year.     

France's Grotian moment? Hugo Grotius and Cardinal Richelieu's commercial statecraft

Cardinal Richelieu's commercial projects have long been seenas a part of his early efforts to reform the French state. Thispaper argues that Richelieu's commercial activity can more profitablybe viewed in the context of his thinking about relations betweenFrance and its neighbours and of a pan-European movement toreconsider the connections among commerce, governance and sovereigntyspawned by the Dutch war with Spain. Specifically, it examinesRichelieu's relations with the Dutch jurist Hugo Grotius. In1626 the cardinal attempted to hire Grotius as a commercialexpert, consulting with him on several occasions. Although Grotiusdeclined, the cardinal was deeply influenced by Grotius’arguments about the freedom of commerce and trade. Richelieuadapted these arguments to suit French needs and his own Catholicvision of the state.     

Pricing, Capacity Choice, and Financing in Transportation Networks

Abstract.  This paper explores interrelations between pricing, capacity choice, and financing in transportation networks. We build on the Mohring‐Harwitz result on self‐financing of optimally designed and priced roads and investigate it in a network environment under various types of second‐best regulation. A small network model with endogenous car ownership demonstrates that optimal congestion pricing and capacity choice over an entire network may cause user prices to increase more in initially mildly congested areas compared to heavily congested areas. Furthermore, a flat kilometer charge under optimal capacity choice may result in first‐best efficiency gains.     

Radiocarbon dating of prehistoric hearths in alpine northern Sweden: problems and possibilities

The chronology of prehistoric Sami settlement sites has previously been established by conventional radiocarbon dating of bulk charcoal samples associated with hearths from sunken hut floors (stállo-foundations). Here we present results of a comprehensive dating exercise of stállo-foundations in the alpine area of northern Scandinavia using Accelerator Mass Spectrometry (AMS) radiocarbon dating of charcoal. Over a 3 km² study area, AMS calibrated ages of hearth charcoal from 22 stállo-foundations across 12 sites securely date these features to between cal. AD 640 and AD 1180. Only small variations in age were found between charcoal samples from different areas of a given hearth. Statistical analysis of all the charcoal AMS radiocarbon dates obtained reveals that 12 stállo-foundations across nine sites are contemporaneous and date to the Viking Period (AD 800–AD 1050). The tightly constrained AMS-based chronology of stállo-foundations contrasts with the existing chronology based on conventional radiocarbon analysis, which places these features within a significantly greater time-frame of between AD 600 and AD 1900, with most dates ranging between AD 800 and AD 1350.This discrepancy is likely to result from the necessity of collecting composite hearth charcoal particles, which may originate from different phases of occupation, in order to achieve the required final carbon content for conventional radiocarbon analysis. We argue that the new AMS-based radiocarbon chronology of stállo-foundations presented here supersedes the existing chronology based on conventional (Gas Proportional counting) radiocarbon analysis and we advocate the use of AMS radiocarbon dating in future hearth investigations.     

Insurgents against Brussels: Euroscepticism and the right-wing populist turn of the Lega Nord since 2013

Under the leadership of Matteo Salvini, the Lega Nord has shifted away from its previous political identity as a voice for Italy’s north and has placed hostility towards the policies and institutions of the European Union (EU) at the heart of its rhetoric. Nowadays, the enemy is Rome no longer: it is Brussels, European institutions, and the threat to the national sovereignty posed by the EU. Borrowing from the Italian political philosopher Nicola Matteucci, we would describe Salvini’s Lega as a ‘populist insurgency’. That is to say, it is a populist party that marries the traditional populist evocation of the virtues of the people against the corrupt elites, with a pervasive glibness of analysis.     

Technoscience,Neuroscience, and the Subject of Politics

Although narrative models have been employed for quite some time in historiography, in sociology, and in certain psychoanalytic theories, the tendency towards narrativization has also become more dominant in reference to the positive sciences. This article presents two postmodern versions of the narrative dissolution of certain modern scientific-metaphysical concepts in the wake of the establishment of technoscience and neuroscience: Vattimo's Heideggerian account of technoscience as immanent pluralization of worlds, and Dennett's cognitivist account of the emergence of the plural self. Both claim not only that former central agencies like the Cartesian cogito can be dismissed as metaphysical but that narrative pluralization entails an (at least implicit) endorsement of liberal democracy as the only viable political model today. Employing arguments put forth by ?i?ek and Malabou, some of the deficiencies of this affirmative short circuit of technoscience/neuroscience with liberal-democratic politics will be examined.
