The awkward years: defining and managing famines, 1944–1947

Abstract

Famines in the years immediately after World War II occurred during a period of global flux, as international famine response evolved from its ambitious, early twentieth century goals toward more modest, technocratic objectives during the second half of the century. For economists, social scientists and politicians immersed in the world of emergency food aid, these were uncertain, awkward years for famine relief. Herbert Hoover’s idealistic large-scale projects of famine relief that had dominated the first three decades of the century had been proven to be expensive and of limited efficacy, but Cold War loyalties had not yet taken over as the primary logic behind large-scale humanitarian assistance projects. Ultimately, when faced with famine conditions between 1944 and 1947, states and experts balanced a call to action against pragmatism that recognized famines were also politically expedient events that could weaken rural resistance to governance and simplify wartime and postwar administration. Ultimately, both science and humanitarian concerns learned to orient themselves toward economic expediency in these awkward years.     

Multiphase flow simulation through porous media with explicitly resolved fractures

Accurate simulation of multiphase flow in fractured porous media remains a challenge. An important problem is the representation of the discontinuous or near discontinuous behaviour of saturation in real geological formations. In the classical continuum approach, a refined mesh is required at the interface between fracture and porous media to capture the steep gradients in saturation and saturation‐dependent transport properties. This dramatically increases the computational load when large numbers of fractures are present in the numerical model. A discontinuous finite element method is reported here to model flow in fractured porous media. The governing multiphase porous media flow equations are solved in the adaptive mesh computational fluid dynamics code IC‐FERST on unstructured meshes. The method is based on a mixed control volume – discontinuous finite element formulation. This is combined with the P_N+1DG‐P_NDG element pair, which has discontinuous (order N+1) representation for velocity and discontinuous (order N) representation for pressure. A number of test cases are used to evaluate the method's ability to model fracture flow. The first is used to verify the performance of the element pair on structured and unstructured meshes of different resolution. Multiphase flow is then modelled in a range of idealised and simple fracture patterns. Solutions with sharp saturation fronts and computational economy in terms of mesh size are illustrated.     

动物考古学与复杂社会——动物群分析在贸易、社会地位和族属研究中的某些应用

自20世纪60年代后期以来,动物考古学成为考古学研究中发展最为迅速的分支学科之一,利用动物骨骼遗存研究复杂社会显示出动物考古学的特殊魅力。本文利用旧大陆西部和新大陆的动物考古学研究案例,首先讨论了动物和动物产品在贸易和交换中的作用,接下来又探讨了动物遗存的差异在多大程度上可以用来重建社会不平等,最后,则批判地考察了动物遗存在辨认史前和历史时代早期族群差异方面的作用。不仅如此,作者还讨论了从事复杂社会研究的动物考古学家所使用的方法,以及这些方法的局限性。作者认为,动物群分析可以作为研究复杂社会经济基础的一个有效方法。动物考古学除了为饮食和生存活动提供有价值的信息之外,动物骨骼分析还可以用于重建过去的交换系统,辨识人们的社会地位和族属。但要做到这一点,动物考古学家必须把分析建立在大量精心收集且出自合适的考古学遗迹单位的动物遗存之上。这意味着动物考古学家必须首先是考古学家,他们应当少花一些时间担心最小个体数、可鉴定标本数以及其他计算生物分类单元丰度的方式的优劣上,而应把更多的时间放在考虑怎样能把动物资料与其他考古学和历史学证据整合起来。因为只有把动物群资料和其他证据结合起来,我们才能理解复杂社会的经济基础。     

Latent trajectory models for space‐time analysis: An application in deciphering spatial panel data

This article introduces latent trajectory models (LTMs), an approach often employed in social sciences to handle longitudinal data, to the arena of GIScience, particularly space‐time analysis. Using the space‐time data collected at county level for the whole United States through webpage search on the keyword “climate change,” we show that LTMs, when combined with eigenvector filtering of spatial dependence in data, are very useful in unveiling temporal trends hidden in such data: the webpage‐data derived popularity measure for climate change has been increasing from December 2011 to March 2013, but the increase rate has been slowing down. In addition, LTMs help reveal potential mechanisms behind observed space‐time trajectories through linking the webpage‐data derived popularity measure about climate change to a set of socio‐demographic covariates. Our analysis shows that controlling for population density, greater drought exposure, higher percent of people who are 16 years old or above, and higher household income are positively predictive of the trajectory slopes. Higher percentages of Republicans and number of hot days in summer are negatively related to the trajectory slopes. Implications of these results are examined, concluding with consideration of the potential utility of LTMs in space‐time analysis and more generally in GIScience.     

Characterization of a Historical Cannonball from the Fortress of San Juan De Ulúa Exposed to a Marine Environment

Metallurgical analyses and chemical characterizations were carried out on historical cannonballs from the Fortress of San Juan de Ulúa, Veracruz, México. Cannonballs dating from the 18th and 19th centuries share metallurgical characteristics similar to those of material coming from a shipment of ammunition found in the wreck of a sunken French ship from the battle of Trafalgar. The analyses show that the base material is grey cast iron with a carbon equivalent of 4.94 and a ferritic–perlitic matrix, in which the high phosphorus content has led to the formation of iron phosphide compounds in conjunction with a homogeneous distribution of carbon graphite flakes of Type C. In addition, corrosion products from samples revealed the presence of various crystalline iron compounds (X‐ray diffraction), mostly highly chlorinated iron compounds identified as akaganeite. X‐ray fluorescence identified various characteristics of the corrosion products as a function of the sampling depth. FT–IR spectroscopy revealed that the main difference between the corrosion products (internal and external) is determined by the number of organic species. Differential scanning calorimetry corroborated that these corrosion products are thermally stable compounds at elevated temperatures.     

A Box Containing Carpenter's Accessories from The Akko 1 Shipwreck,Israel: Archaeometallurgical Analysis of Surviving Ironwork

The Akko 1 shipwreck was an Egyptian armed vessel, built at the beginning of the 19th century. A wooden saw handle and a box containing iron nails and two split pins were discovered towards the stern. Given their function, location and context, these were part of the ship's carpenter's tools and accessories. A methodology was developed for conducting systematic metallurgical analysis in order to understand the manufacturing process of the surviving ironwork items, as well as to enlarge our knowledge regarding ironworking technologies during the early 19th century. Such methodology may assist in the future understanding of the technological evolution of similar wrought‐iron objects. The results demonstrated that the artefacts have a wrought‐iron heterogeneous microstructure and were manufactured by hot‐working prior to surface hardening by pack carburization.     

CONTEXTS OF COLONIALISM

The contributions to the collection under review offer a wide range of treatments of ways in which German colonialism intersected with aspects of domestic German culture and politics, with particular attention to the larger global setting in which the German colonial empire existed between 1884 and 1918—or was remembered up to 1945. The review situates and critiques the contributions in interpretive contexts based on general suggestions by one of the editors, Geoff Eley. These include a context in which “colonialism” and “imperialism” are recognized as specific discursive constructions of the late nineteenth and early twentieth centuries, another in which the causal focus in interpreting colonial phenomena is placed on exchanges that constituted an accelerating globality with which available conceptual modes (including colonialism and imperialism) could not keep pace, a third that complicates the categorical distinctions usually made between types of imperial program, and a fourth that aims at replicating on a much broader and more flexible basis something like the concept of “social imperialism” that forty years ago dominated interpretations of German imperialism. The essay ends with a view of how such an interpretive framework might be constructed.
