Mozambican archaeology: past and present

After a brief survey of the development of archaeology in Mozambique, the results of the archaeological survey programme of 1976–1983 are summarized by region. Work currently in progress is evaluated in the light of archaeological and national priorities and the paper concludes with a discussion of the theoretical approach best suited to Mozambican conditions.

Evaluation of Structural Intervention in the Quartel das Esquadras,Almeida (Portugal)

ABSTRACT

The “Quartel das Esquadras” is an 18th century infantry barrack located within the limits of the bulwarked fortress of Almeida, in Portugal. An ongoing adaptive reuse project of the building aims to recover its full capacity and also its importance, by implementing a variety of new uses. The architectural intervention results in the need of the structure to withstand new and diverse imposed loads. As the current configuration of the structure will be altered, the main objective of this article is to evaluate the suitability of some of the proposed structural interventions. The current condition has been characterized following a multidisciplinary approach comprising historical research, visual inspection, non-destructive testing, and structural analysis to identify the possible sources of major structural problems. A portion of the building particularly affected by the alterations has been selected to carry out structural analysis. A comparative safety assessment of the selected area in both current and altered condition has been done through finite element modelling and nonlinear static analysis, resulting in an identification of the weaker points against the new implemented loads and alterations. Finally, proposals for the implementation of the studied intervention, as well as recommendations for future research and analyses, have been given.     

Updating Numerical Models of Masonry Arch Bridges by Operational Modal Analysis

This article aims at presenting and discussing the strategies for updating the finite element numerical modeling of stone masonry arch bridges using operational modal analysis. The study comprehended three bridges: two old ones, the St. Lázaro and the Lagoncinha bridges, and a recently constructed bridge in Vila Fria, Portugal. Updating of the bridge models is performed by comparing the numerical and experimental modal parameters. Three-dimensional detailed numerical models are used to perform modal analysis of the bridges. Experimental modal identification of the bridges is based on the measurement of their acceleration responses during normal operation. The assigned material properties are also based on available results obtained from in situ and laboratory tests and on the results of visual inspection and historical research carried out for both old bridges.     

A place in the sun? Discursive constructions of positive outcomes in post-migration stories in the Algarve

This study argues for more comparative research between seemingly different migrant groups, bringing a new focus on intra-European migration in Portugal by examining and comparing the reasons why migrants from different geographical origins choose to settle in the tourism-based Algarve region. Drawing on data collected from a questionnaire survey and interviews, the study first compares the profiles of two apparently distinct migrant groups – Northern and Eastern Europeans – and goes on to explore their discursive representations of migration experiences. Findings reveal that despite differences in initial motivations for moving to the Algarve, there are similarities between the two groups in terms of what leads them to settle in the region. Among both groups there is a high level of positive place-identity, suggesting that the specific context of the destination place plays a significant role in positive post-migration outcomes, something which is often overlooked in migration studies. Furthermore, the lived and perceived lifestyle affordances of the destination place, especially when discursively compared with the place and lifestyle left behind, are flagged by both groups and lend support to the idea that the role of lifestyle in migration has a wider significance than is usually credited.     

Final Strategy: The Post-War Grand Strategic Designs of Henry L. Stimson

Few men arguably shaped the trajectory of American foreign policy in the twentieth century as durably and profoundly as Henry L. Stimson. After all, Stimson was not only directly involved in many consequential decisions dealing with highly important matters of war and peace, but was also a major influence in the United States’ more proactive involvement in extra-territorial affairs. For Stimson, it was simply wishful thinking to presume that the United States could forever disengage itself from far-reaching occurrences in other parts of the globe. Accordingly, he thought it just as critical to anticipate international problems as it was to successfully resolve them afterwards, with the result that he became an ardent and early proponent of a much more sophisticated global strategy after the Second World War. In that context, however, most historians have primarily focused on Stimson's role in the development and use of the atomic bomb against Imperial Japan, though arguably less on his more sweeping grand strategic designs. Consequently, the present article will attempt to offer a more comprehensive analysis of Stimson's grand strategic designs, particularly as they related to his vision and reflections on the necessary ingredients of a more peaceful, stable and secure interstate system.     

A New Methodology and Classification System for Describing Three‐Dimensional Particle Formats: Application to Clastic Lithic Products of Archaeological and Geological Origin

A new classification system is proposed to describe the volumetric formats of clastic lithic products of geological and archaeological origin. In order to build this operative classification, the rectangular block or cuboid is established as the standard geometric format to represent their three‐dimensional format (the X‐axis being length or long diameter, the Y‐axis being the width or intermediate diameter, and the Z‐axis being the thickness or short diameter) on a two‐dimensional diagram. To obtain this graph, each absolute coordinate (X, Y, Z) defining the prisms is projected on to an auxiliary plane with a new set of relative coordinates (x, y, z), expressed as the percentage of their sum. The projection generates a triangular diagram on which the indices of elongation and flatness are represented. A geometric transformation converting the triangular diagram into a quadrangular diagram has been produced in order to better represent the scatter points. Then, a double scale is necessary: (i) an absolute scale to quantify the indices, and (ii) a relative scale to calculate where the graphic locus is projected. This new graph also allows us to work with statistical parameters. Finally, two classic examples of applications selected from the literature are shown.
