A Long Time Gone: Post‐conflict Rural Property Restitution under Customary Law

Mass displacement of people due to violence poses a unique set of challenges for property restitution when people return to their homes after a long absence. This is particularly evident in rural areas where the dominant form of land holding is customary tenure. Violence‐induced displacement, unlike voluntary migration, challenges both customary and public legal‐administrative structures. The lack of written documentation of customary holdings and the importance of the support of community leaders means that incorporating returnees back into a community can be easier for those who choose to return, while reclaiming property without physical return is nearly impossible. This article seeks to make three contributions: 1) to note the diversity of return processes after long displacements in terms of timing and demographics; 2) to demonstrate that the nature of the claims people can make on customary tenure systems is at odds with international legal norms on property restitution after displacement; and 3) to introduce a set of observations and questions on how conflict can change customary law. The article is based on fieldwork conducted in Uganda, Liberia and Timor‐Leste, all countries with extended displacement where most of the rural land is held via customary claims.     

Petrochemical Identification and Insights on Chronological Employment of the Volcanic Aggregates Used in Ancient Roman Mortars

Through the assistance of trace element and petrographic analyses on 14 samples of mortar aggregates from Roman monuments, including the Porticus Aemilia, the Temple of Concordia, the Temple of the Dioscuri, Temple B and other structures of the Area Sacra di Largo Argentina, and the Villa di Livia, we establish the source area and we investigate the chronological employment of the volcanic materials used in ancient Rome's masonry. In contrast to previous inferences, the petrochemical data presented here show that systematic exploitation of the local ‘Pozzolane Rosse’ pyroclastic deposit has occurred since the early development of concrete masonry, at the beginning of the second century bc , through the early Imperial age. Subsequently, exploitation was extended to the overlying Pozzolane Nere and Pozzolanelle deposits. Only during the early phase of development of the concrete masonry in Rome, volcaniclastic sediments outcropping near the construction sites were mixed with the sieved remains of the tuff employed as the coarse aggregate, to produce the fine aggregate. The results of the study on the investigated monuments suggest the possibility of establishing the chronological identification of three different types of mortars, as a function of the composition of the volcanic material employed in the fine aggregate, which, when implemented by future studies, may contribute to the dating of monuments and archaeological structures.     

Preliminary Characterization of Pottery by Cathodoluminescence and SEM–EDX Analyses: An Example from the Yeha Region (Ethiopia)

Yeha was a political and cultural centre of the Ethio‐Sabaean culture (D’MT) in northern Ethiopia and southern Eritrea. Part of the archaeological research deals with pottery of local, regional and imported origin. The research—investigations and examinations—tries to classify local pottery in two ways: first, by analysing the mineralogy of the temper using light microscopy and cathodoluminescence; and, second, by analysing the main element composition of the clay matrix using a scanning electron microscope with energy‐dispersive X‐ray detection (SEM–EDX). The cathodoluminescence shows that the temper material has differences in the colours of feldspars with a similar mineralogical composition. The results demonstrate that the pottery was produced by using local material that originates from various sources in the Yeha region and that the same raw materials were used in different types of pottery.     

The Architectural Reuse of Roman Marble and Stone Spolia in the Early Medieval Monte Sorbo Church (Sarsina,Central Italy)

We present the results of a multi‐method archaeometric study concerning the architectural elements reused in Monte Sorbo church (Sarsina, central Italy) between the eighth and ninth centuries AD . The provenance study has focused on classical marbles and stones, which clearly do not originate from the local Apennine geological formations and are thought to come from extra‐regional sources. A large fraction of the tested marbles is from Asia Minor, coming from both the Proconnesian district on Marmara Island and, probably, the Hasançavuslar site near Ephesus (Greco scritto). Of the four remaining marbles investigated, one is from the Carrara district and three are from different Greek quarrying areas, such as Mount Pentelikon (Athens) and the Thasos and Paros islands. The data also highlight the reuse of decorated gravestones made of Pietra di Aurisina as architectonic elements. This limestone is a fossiliferous carbonate stone outcropping in the Trieste Karst region (north‐eastern Italy), which was exploited by both the Romans and the Byzantines. The assignment of all of the columns of the central nave to the same source area provides an argument in favour of their provenance from a single monument, which was probably located in Sarsina or Ravenna, with the ‘colourful taste’ that is typical of the late Antonine and Severian periods.     

Middle Bronze Age Arsenical Copper Alloys in Southern Portugal

In the Iberian Peninsula, the copper metallurgy from the Chalcolithic to the Middle Bronze Age (MBA) was mostly characterized by low arsenic contents. A collection of 53 MBA artefacts from southern Portugal was analysed by micro‐EDXRF, optical microscopy, SEM–EDS and Vickers to investigate the metal composition and manufacture. No technological distinction was found between artefacts from domestic and funerary contexts, which were radiocarbon‐dated to 2000–1500 cal bc . The arsenic contents of almost 100 MBA artefacts from this region, including the above‐mentioned set, have a Gaussian distribution with a high average (3.9 wt% As). Possible explanations are discussed for this distinctive metallurgy at the south‐western end of the Iberian Peninsula.     

The preservation of exposed mudbrick architecture in Karanis (Kom Aushim), Egypt

Excavations in the arid regions of Egypt provide insight into the many types and uses of mudbrick architecture. Upon exposure the inherently unstable building material decays rapidly, resulting in severe loss or complete destruction of once well-preserved buildings. The preservation of mudbrick structures is relatively complicated and expensive. Research has focused on the circumstances that enable preservation and the influence of climate and weather over time. Conservation treatments should address these two processes as soon as possible after exposure of the structures. Our assessment of a range of conservation methods leads to the conclusion that reburial is among the least objectionable method of preservation, despite its drawback of returning the excavated buildings to a situation where they are invisible to both researchers and the public.     

Auf gute Nachbarschaft!

Companies' community involvement turns out to be spatially relevant and–in many cases–to be focused on the near surroundings of the place of business. Some companies strategically align their involvement in order to systematically address local challenges. The essay at hand addresses the subject of corporate social responsibility from a local development perspective. Using the example of two family-owned enterprises based in Duisburg, Haniel and Grillo, it illustrates how socially committed companies can get involved with their local community by acting as good neighbours. Furthermore, it argues that socially committed companies can function as producers of space concerning matters of urban and local development. The specific local settings as well as the economic conditions of the local community serve as an explanatory background of the companies' involvement. The cases presented in this paper prove the firms' specific knowledge of local development needs and possibilities. This makes them qualified partners for local government actors and civil society actors. Thus, in the future, it is worth addressing corporate local responsibility from a governance point of view both in theory and in practice.     

„Was für Grün in der Stadt?“

Urban green space is a key subject of actual urban negotiation processes on how the city shall develop. Visions of the ideal city are reflected in the meanings currently ascribed to urban gardening. Thereby the relation between human and nature as well as between build and natural environment in the city plays a central role. Results from different Swiss cities show that allotment gardens as well as newer forms of urban gardening are oscillating between a compensatory and a complementary understanding of nature, and they equally combine the desire for pristine nature with the demand for functional green space in the city.     

Studying the International,Serving the Nation: The Origins of International Relations (IR) Scholarship in Germany, 1912–33

This paper examines the dynamics of internationalist and nationalist political thought in the formation of International Relations (IR) scholarship in Germany during the early twentieth century. It argues that while liberal internationalism played a significant role in shaping the discipline, IR scholars were often devout nationalists and worked for their government rather than for international peace. German institutions for the study of IR, like their Anglo-American counterparts, were founded in the aftermath of the First World War. Celebrated during the 1920s as ‘bulwarks of democracy’, they were nationalised by the Nazi government, lost their academic profile and since then have been largely forgotten. This paper explains the origins of IR research at the Institut für Auswärtige Politik, based in Hamburg and directed by Albrecht Mendelssohn Bartholdy, as well as at the Deutsche Hochschule für Politik, led by Ernst Jäckh in Berlin. Formally inaugurated in 1923 and 1920 respectively, both institutions drew on pre-war intellectual traditions as well as wartime networks. In light of recent re-appraisals of inter-war IR scholarship in other countries, the German case offers new and important insights into the complex intellectual traditions of what has traditionally been oversimplified as a first ‘great debate’ between ‘idealists’ and ‘realists’.
