Inelastic Displacement Response of RC Systems with Cyclic Deterioration—An Energy Approach

Inelastic displacements of reinforced concrete systems are investigated by employing an energy-based approach. A hysteresis model is developed that accounts for stiffness degradation, strength deterioration and pinching. The model is calibrated by using experimental data from literature. Inelastic displacement ratios are calculated under a specific set of ground motion records with long effective durations. The results reveal the importance of deteriorating behavior under long duration excitations, especially for short and medium period structures. The last part of the study is devoted to the introduction of a simple empirical relationship for estimating the inelastic displacement demands of degrading RC structural systems.     

What has Iberia to do with Jerusalem? Crusade and the Spanish route to the Holy Land in the twelfth century

In spite of repeated papal injunctions forbidding them to abandon their homeland, Iberian Christians, like their co-religionists throughout Europe, were energised by a desire to participate in the Holy Land crusades. The most significant and creative attempt in the first half of the twelfth century to respond to this Spanish desire was the development of the idea of the iter per Hispaniam, which was fostered by Iberian archbishops and monarchs such as Diego Gelmírez of Santiago de Compostela and Alfonso I of Aragon. This Spanish route was intended to unite the conflicts in the peninsula and the Holy Land, forming a single Mediterranean-wide crusading theatre and thereby granting the Iberian conflict a deeper connection with the struggle for control of the holiest sites in Christendom. This article explores the development of crusading ideology in Spain and the difficulties of doing so in a venue outside of the Holy Land. Additionally, the development of the Spanish route idea provides a unique opportunity to contextualise recent historiographical discussions about the essence of the crusades and to highlight the way in which different perspectives helpfully offer insight into various aspects of peninsular crusading.     

Hunted or Scavenged Neanderthals? Taphonomic Approach to Hominin Fossils with Carnivore Damage

Carnivore damage on Neanderthal fossils is a much more common taphonomic modification than previously thought. Its presence could have different explanations, including predatory attacks or scavenging scenarios, which are both situations with important implications concerning Neanderthal behaviour. In the present paper, we analyse several Neanderthal hominin fossils from a taphonomic and forensic perspective in order to infer the nature of the modifications observed on the bone surfaces. Fossils displaying carnivore modifications from Spain, Germany, Belgium and Greece are evaluated from a taphonomic perspective for the first time in a significant sample of hominin specimens. Our results show that the materials analysed have been modified by small to large carnivores and that both attacks and strictly carnivore scavenging events can be inferred. This study also points out the importance of developing taphonomic approaches to the analysis of hominin bone surfaces, which can contribute significantly to knowledge of several aspects of Neanderthal behaviour.

Increasing Behavioral Flexibility? An Integrative Macro-Scale Approach to Understanding the Middle Stone Age of Southern Africa

The Middle Stone Age (MSA) of southern Africa represents a period during which anatomically modern humans adopted a series of diverse cultural innovations. Researchers generally attribute these behavioral changes to environmental, neurological, or demographic causes, but none of these alone offers a satisfactory explanation. Even as patterns at site level come into focus, large-scale trends in cultural expansions remain poorly understood. This paper presents different ways to view diachronic datasets from localities in southern Africa and specifically tests hypotheses of environmental and cultural causality. We employ an array of analyses in an attempt to understand large-scale variability observed during the MSA. We evaluated the diversity of stone tool assemblages to model site use, examined transport distances of lithic raw materials to understand patterns of movement, assessed the cultural capacities required to manufacture and use different sets of tools, applied stochastic models to examine the geographic distribution of sites, and reconstructed biome classes and climatic constraints. Our large-scale analysis allowed the research team to integrate different types of information and examine diachronic trends during the MSA. Based on our results, the range of cultural capacity expanded during the MSA. We define cultural capacity as the behavioral potential of a group expressed through the problem-solution distance required to manufacture and use tools. Our dataset also indicates that the actual behavior exhibited by MSA people, their cultural performance as expressed in the archaeological record, is not equivalent to their cultural capacity. Instead we observe that the main signature of the southern African MSA is its overall variability, as demonstrated by changing sets of cultural performances. Finally, at the scale of resolution considered here, our results suggest that climate is not the most significant factor driving human activities during the MSA. Instead, we postulate that behavioral flexibility itself became the key adaptation.     

Conditionality and the EU–ACP Partnership: A Misguided Approach to Development?

The Cotonou Partnership between the states of Africa, the Caribbean and the Pacific (ACP) and the European Union (EU) provides a case in which the human rights approach to development is being put into practice. This article uses the partnership to address broader questions regarding the effectiveness of the new approach to development. The EU–ACP partnership is innovative because it reflects the changing international consensus on development, but it is not clear if the norms used in the Cotonou Agreement have achieved the consensus needed to comprise any real shift in development policy. Moreover, it can be argued that what diminishes the efficacy of the human rights approach in the EU–ACP relationship is political conditionality as this mechanism may lead to interventions that are counterproductive to the establishment of stable democracy.     

Short Note: Provenancing of Pottery— The Need for an Integrated Approach?

The method of chemical provenance determination of pottery is described as a very useful tool, which gives reliable results in most cases, if it is applied correctly and to its full power. Therefore, it is claimed that additional petrographic analysis, the so‐called ‘integrated approach’, should not be considered as a must for each project, but is only needed in cases in which the chemical approach leaves questions to be answered.

What is Nationalism Really? Understanding the Limitations of Rigid Theories in Dealing with the Problems of Nationalism and Ethnonationalism

Abstract. This article examines major approaches to nationalism and ethnonationalism and posits a more flexible definition than that which is prevalent in these theories. It then goes on to look at how a more flexible approach to the study of nationalism can be used as a lens to both define and address the sources of nationalist and ethno-nationalist conflicts. The flexible approach leads to the conclusion that the character of a particular nationalism is highly context-sensitive and that the best way to understand the problems it creates is through an understanding of how the different levels of society interact with one another as well as with the outside world.     

Whose Modernity? Indigenous Modernities and Land Claims after Apartheid

This article questions some of the key assumptions of post‐development and anti‐development critics such as Arturo Escobar and Wolfgang Sachs, who tend to prescribe a puritanical and principled rejection of ‘exogenous development’ that does not necessarily reflect the needs and desires of the beneficiaries of development. Drawing on fieldwork research on land claims in Northern Cape and Northern Provinces (South Africa), the author argues that these beneficiaries tend to deploy hybrid and highly selective and situational responses to development interventions. These hybrid responses can be regarded as indigenous modernities. Development packages are resisted, embraced, reshaped or accommodated depending on the specific content and context. The author also questions James Ferguson's conclusion that depoliticizing development discourses inevitably buttresses bureaucratic state power. Rather, the fieldwork findings suggest that state‐led development is often an extremely risky business that can undermine the legitimacy and authority of governments. In addition, in many parts of the developing world, it is the retreat of the neo‐liberal state, rather than ‘the tyranny of development’, that poses the most serious threat to household livelihood strategies and economic survival. The case studies discussed here suggest that responses to development are usually neither wholesale endorsements nor radical rejections of modernity. Even when resisting and subverting development ideas and practices, people do not generally do so on the basis of either radical populist politics or in defence of pristine and authentic local cultural traditions.     

“A Chronicle of a Death Foretold”: Urban Expansion and Land Consumption in Rome,Italy

The article analyses the long-term changes in the spatial distribution and density of the urban settlements in Rome (Italy), a compact Mediterranean city recently undergoing low- and medium-density expansion. Eight density classes were considered: no buildings, <0.5 buildings per hectare, 0.5–1.0, 1–2, 2–3, 3–5, 5–10, >10 buildings per hectare. Non-urbanized land amounted to 89% of the investigated area in 1919 and fell to 30% in 2001. Building density increased over time suggesting that both concentration and diffusion processes occurred in the study area. During 1919–2001, the building density was stable in only 37% of the investigated land. In that period, the largest part of the area (47%) underwent a low increase in building density, while 12% of the area passed from a low-density to a high-density class. Settlement density decreased rapidly with the distance from the city centre in 1919 and 1945, while a marked increase was observed in areas progressively further away from Rome since 1961. In recent years, land consumption was partly determined by the planning strategies adopted by Rome's municipality with the aim of producing a more balanced and polycentric region. More effective policies preserving the quality of the environment and promoting the sustainable development of peri-urban Mediterranean regions are needed.     

Wasting Coconuts? Consumption Versus Commerce in Colonial Wallis and Futuna

ABSTRACT

Early colonial officials and other newcomers frequently lamented the poor copra production in Wallis and Futuna, positioning the continued consumption of coconuts by Islanders as a waste. This article explores the contested uses of coconuts and the divergent visions of the islands’ landscape and future held by Islanders, officials, missionaries and traders during opening decades of French colony rule. In particular, a variety of incidents in the 1920s – from an indigenous co-operative to French expulsions – highlight the centrality of the emergent copra trade to the social and political status of these different groups. More broadly, however, the article demonstrates the failure of elites – both indigenous and newcomer – to substantially increase copra exports prior to the Depression in 1930, indicative of the limits of their ability to demand labour and transform the lifeways of the wider population.     

Talking to the Muslim world: how,and with whom?

The struggle against terrorism in the Middle East, and the success of the Islamic State in Iraq and Syria in its use of social media to spread its ideas, has led to a search for new messages to counter the appeal of violent extremists. Thus far, United States counter‐messaging has failed to articulate a normative position that is compelling to its target audiences. The US has also not found an effective way to speak to and with other parts of the Muslim world. The article shows that these failures are not accidental but reflect profound factors in American culture and society. The US’ normative position has also failed to take into account the crucial differences between ‘liberals’ and ‘moderates’ in the Muslim world. To proceed one must acknowledge that there are two fundamentally different interpretations of Islam, both of which are supported by a close reading of the Qur’an and other major texts. To draw on that difference, the article shows, requires drawing on voices and resources not available in the US. The article proposes a way forward that both acknowledges the inherent weaknesses and liabilities of the US government as a messenger and points to more credible messengers within the Muslim world.     

An end to collective identities? Political culture and voting behaviour in Sesto San Giovanni and Erba

This paper addresses the question of the demise or resilience of political subcultures in Italy today, focusing on two areas, Sesto San Giovanni and Erba, characterized until recently by a socialist/communist subculture and a Catholic/interclassist one. The voting behaviour and political values of key social groups, above all industrial workers, in these two towns provides evidence of the persistence and indeed revival of political subcultures in Italy. The paper argues that their function has changed, though. Whereas in the past a political subculture encompassed the whole spatial community, nowadays it appears to represent the interests and needs of specific groups within a territory, thus becoming one of many political instruments and choices open to social actors and voters.     

Making the Dead Visible: Problems and Solutions for “Big” Picture Approaches to the Past,and Dealing with Large “Mortuary” Datasets

There can be few “bigger” questions than the nature and development of human experience and self-awareness and few better ways to study it than through the changing treatment of the dead over time. Funded by the John Templeton Foundation, the ‘Invisible Dead’ project (Durham University) is exploring diachronic changes in mortuary practices across two regions: Britain and the Levant. In doing so, it uses archaeology as a way to approach fundamental questions about the human condition. This paper explores the principal difficulties faced during the construction of a database for this project and their wider relevance for the development of robust and successful methods for the study of large “mortuary” datasets in the future. It discusses the issues and biases identified within the mortuary record and how the project has sought to mitigate some of these. By adopting a flexible and ultimately expandable approach to data entry and analysis, value can be added to legacy datasets and “grey” literature, allowing us to make comparisons between regions which are both geographically and chronologically distinct.     

Recreating the Judean Hills? English hermits and the Holy Land

This article explores the place of the Holy Land in the devotions of medieval English hermits and recluses between the eleventh and thirteenth centuries. It first outlines the importance of physical travel to Palestine in the career of anchorites, with pilgrimage to Jerusalem followed by seclusion held up as a powerful ideal in literary sources. It then suggests that some of the dwellings of English solitaries formed deliberate monumental recreations of the holy places of Palestine. It considers the extent to which the cells of recluses were understood as recreations of the tomb of Christ, functioning as living Easter Sepulchre structures, and the dedication of churches used or built by hermits and recluses. Finally, it notes possible links between the hermitage of St Robert of Knaresborough and Jabal Quruntul (Mount Quarentayne), the site of Christ's temptations in the wilderness.     

Qualitative Landscape Theories and Archaeological Predictive Modelling—A Journey Through No Man’s Land?

An approach to test and interpret geographic information system-based, quantitative archaeological predictive models using techniques from qualitative (experiential) landscape theory is described and demonstrated via a case study. The result is the transformation of statistical output from quantitative predictive models into more archaeologically meaningful interpretations of spatial data.     

A Quantitative Approach to Book-Printing in Sweden and Finland, 1640–1828

Several cities in Sweden have been providing book-printing facilities since the 1640s. In our quantitative and explorative analysis of library catalogs from the National Library of Sweden and the National Library of Finland we identify the general trends in publishing, how book-printing has been affected by political events, and how printing developed at different paces in different parts of the realm. We have developed a new method for analyzing the totality of publishing through extensive data harmonization and comprehensive statistical analysis, and by treating library catalogs not as an endpoint of bibliographic research but as an inherently rich source of information. This facilitated the quantitative assessment of printing in the Swedish realm based on the metadata contained in library catalogs. Our data-driven approach to the transformation of public discourse demonstrates that whereas the amount of printed material grew steadily, political ruptures affected the development of printing. We also suggest that the culture of books and printing is best understood through the dynamics of competing intellectual hubs consisting of the university cities and the political center in Stockholm. This perspective further challenges the dominant, nationally delineated approach in book history.
