Military Orders Between Territorialization and Periphery from the 12th to the 16th Century

Military orders have historically played a key role in defining borders, both in a mental sense, by favouring an awareness of alterity in the most peripheral territories (Christians against Muslims and Christians against Pagans), and also in more direct ways, as owners of land in these territories. This article¹ discusses both the influence, in the broadest sense, of territory and periphery upon the medieval military orders, and the relationship between the crown and the military orders. It will be done through a comparative historical analysis of two cases: Portugal and Denmark in the 12th–16th centuries. Both countries were placed at the periphery of the Western world in the Middle Ages, and they were both active agents in the Crusading movement.     

The Evolution of Population Distribution on the Iberian Peninsula: A Transnational Approach (1877–2001)

Abstract

Surpassing the national perspective usually adopted, the authors confirmed the existence of a pattern of population distribution common to the whole Iberian Peninsula in the long run. This pattern is clearly associated with geographical factors. These variables seem to have more weight in explaining changes between 1877/78 and 1940 than in the period from 1940 to 2001. The observation of the cross-border region has shown that proximity to the frontier has not generated any distinct pattern of population density on either side of the boundary line. The spatial coherence of the observed phenomena throughout the Peninsula and of its evolution, independent of the border between states, reinforces the importance of geographic factors in their explanation. At the same time, this verification opens up new issues related to the effect of national political and economic policies.     

A graph-based analysis for generating geographical context from a historical cadastre in Spain (17th and 18th centuries)

Abstract

The cabreves are notarial documents prepared between the 13th and 19th centuries in the Catalan and Valencian regions of Spain. These historical records were published before the first cadastral maps and contain geographical information that could help spatially reconstruct historical landscapes. However, these documents have not been used to their full potential mainly because of their semi-structured and complex nature. In this article, we propose a new graph-based interactive methodology for partially reconstructing historical landscapes. We have successfully applied this methodology for reconstructing the historical landscape of the Barony of Sella in the 18th century and the methodology has also helped us locate “El Poblet,” a previously unknown archeological site abandoned after the expulsion of the Moriscos in 1609.     

Multi-Component Seismic Response Analysis – A Critical Review

Issues related to multi-components seismic response analysis are critically reviewed and their implications with respect to the current codified approaches are studied. The issues specifically addressed are: (1) the directions of earthquake forces to excite a structure when the direction of the potential epicenter is known; (2) different commonly used combination rules to obtain the critical response when responses are available in different directions; and (3) the applicability of the combination rules for elastic and inelastic analyses. Based on an extensive parametric study consisting of three-dimensional 1-, 3-, 8-, and 15- story buildings made of moment-resisting steel frames and 20 recorded earthquakes, it is observed that the principal components produce larger responses than the normal components. The 30% and SSRS rules generally underestimate the axial loads in columns. The 30% combination rule is slightly better than the SSRS rule. For both rules, the uncertainty in the estimation of the axial loads in terms of COV is very large (about 25%). The statistics obtained for axial loads and total base shear indicate that the combination rules are applicable for both elastic and inelastic cases. The critical response could be obtained for an orientation different from that of the principal components. The differences are found to be slightly greater for the scaled earthquakes producing a considerable inelastic behavior. Considering the enormous amount of efforts needed to address the directionality effect, it is believed that the responses obtained by the principal components will be acceptable in most cases; however, for critical structures the components should be rotated to obtain the critical responses.     

Experimental Dynamic Behavior of Free-Standing Multi-Block Structures Under Seismic Loadings

This article describes the dynamical behavior of free-standing block structures under seismic loading. A comprehensive experimental investigation has been carried out to study the rocking response of four single blocks of different geometry and associations of two and three blocks. The blocks, which are large stones of high strength blue granite, were subjected to free vibration, and harmonic and random motions of the base. In total, 379 tests on a shaking table were carried out in order to address the issues of repeatability of the results and stability of the rocking motion response. Significant understanding of the rocking motion mechanism is possible from the high quality experimental data. Extensive experimental measurements allowed to discuss the impulsive forces acting in the blocks and the three-dimensional effects presented in the response.     

Statistical Characterization of Structural Demand under Earthquake Loading. Part 2: Robust Estimation of the Dispersion of the Data

Performance-based earthquake engineering methodologies often require a probabilistic model of structural demand. Since observations masking the probability distribution of the majority of the data are frequently found, robust estimation methods are proposed to estimate the probabilistic model parameters (i.e., central value and dispersion). The performance of thirty-three robust dispersion estimators is evaluated, for different sample sizes, using the chord rotation, curvature, shear force, and inter-story drift demands obtained after analyzing five reinforced concrete structures under real earthquake records scaled to several intensities. Based on the results, combinations involving dispersion and central value (defined in a companion article) estimators are proposed.     

Catalan linguistic policy: liberal or illiberal?

Abstract. This article analyses the discussion, enactment and characteristics of the Linguistic Policy Act adopted by the Catalan Parliament in 1998, from the point of view of current normative political theory. The main theoretical question is whether its provisions promoting the Catalan language are compatible with the liberal political tradition, considering its different streams. The discussion shows that the main arguments are not different from those used by scholars dealing with issues of national and cultural pluralism in Western democratic societies. Thus, the opponents of the Act tend to rely upon various individual rights‐based arguments taken from classical liberalism. Its advocates, on the other hand, accuse them of neglecting the value of cultural membership, asserted by influential authors within the liberal tradition. Ultimately, the article concludes that this law neither promotes nor allows illiberal practices.     

Holocene fire history of black colluvial soils revealed by pyrolysis-GC/MS: a case study from Campo Lameiro (NW Spain)

The colluvial soils of Galicia (NW Spain) are records of Holocene environmental change. In spite of the omnipresence of charcoal fragments in these soils, the effect of fires on the development of the Galician landscape and the potential role of past societies are poorly understood.
