Structural Assessment of Companhia Aurífícia,a 19th Century Industrial Building Located in Northern Portugal

Companhia Aurifícia is located in Porto, Portugal, and was founded in 1864. It was a pioneer factory in the industrial production, casting, rolling, and stamping of metallic objects and laboured for about 150 years, in areas as jewelry, manufacture of parts in silver and gold or the production, and casting of various metals. In 1866, it began laboring in Rua dos Bragas, its present location, and in 2003 ceased all activities.Companhia Aurifícia is an industrial complex including several buildings, all located in the same block. It is a precious example of the industrial architecture in Porto, where the still existent retaining walls, structures, machinery, and decorative elements make it one of the last examples of 19^th century industrial life of the city.This article aims to evaluate the safety condition of one of the buildings included in this industrial complex, in order to propose the necessary strengthening interventions.     

Stability of Slender Masonry Columns with Circular Cross-Section under Their Own Weight and Eccentric Vertical Load

This work concerns the stability of unreinforced masonry slender circular cross-sectional columns subjected to their own weight and eccentric vertical load. Cantilever columns are examined, considering that the material has infinitely linear elastic behavior in compression and has no tensile strength. For the analysis, an existing numerical model and solution procedure developed for the stability analysis of masonry elements with rectangular cross-section are utilized and adapted to the circular columns. For the instability of the columns, an appropriate criterion that relates the top lateral deflection to the intensity of the applied eccentric vertical load is employed. By considering a reference column, critical buckling load is obtained, behavior of the column interpreted and efficiency of the numerical model emphasized. Performing a nonlinear buckling analysis using a general purpose software on this reference column, obtained results are compared with those of the adapted procedure of the present study. Implementing parametric analyses on reference column, effects of the column slenderness, eccentricity of vertical load, elastic modulus, and self-weight on the buckling load are investigated. Presented calculation procedure provides a useful tool in order to calculate the critical loads or to check the stability of masonry circular columns.     

Simple Seismic Assessment of Traditional Unreinforced Masonry Buildings

A framework for quick seismic assessment and retrofit of traditional unreinforced masonry (URM) structures is presented. The proposed methods build on simple principles of structural dynamics and are used as an alternative to detailed time-history analysis, in recognition of the prevailing need for simple and practical methods, compatible with the low-budget and the limited level of knowledge regarding materials, internal force paths, connectivity and condition of older URM structures. An objective is to identify areas in the building that are particularly susceptible to damage and for guiding the types of the required global interventions to improve seismic response. Demand and supply are expressed in terms of relative drift ratios that quantify the intensity of out-of-plane differential translation and in-plane shear distortion of masonry walls. A characteristic traditional building type of timber-laced masonry is used as a model structure for illustration of concepts. The morphology and geometry of the building correspond to a statistical sample of the actual traditional unreinforced masonry buildings (TURM) found in historical centers of many towns in the greater region of Northern Greece. The methodology is particularly useful for setting retrofit priorities and management of the collective seismic risk of historical entities.     

Network Analysis and Entanglement

This article explores the extent to which formal network analysis can be used to study aspects of entanglement, the latter referring to the collective sets of dependencies between humans and things. The data used were derived from the Neolithic sites of Boncuklu and Çatalhöyük in central Turkey. The first part of the analysis involves using formal network methods to chart the changing interactions between humans and things at these sites through time. The values of betweenness and centrality vary through time in ways that illuminate the known transformations at the site as, for example, domestic cattle are introduced. The ego networks for houses across four time periods at the two sites are also patterned in ways that contribute to an understanding of social and economic trends. In a second set of analyses, formal network methods are applied to intersecting operational chains, or chainworks. Finally, the dependencies between humans and things are evaluated by exploring the costs and benefits of particular material choices relative to larger entanglements. In conclusion, it is argued that three types of entanglement can be represented and explored using methods taken from the network sciences. The first type concerns the large number of relations that surround any particular human or thing. The second concerns the ways in which entanglements are organized. The third type of entanglement concerns the dialectic between dependence (potential through reliance) and dependency (constraint through reliance).     

Reflections on the Identities and Roles of the Artists in European Paleolithic Societies

In an attempt to introduce concerns with social identities into the discussion and understanding of the making of what we call Paleolithic art, this article considers issues of gender, skill, apprenticeship, and tradition. We note that, as in every period of history, Paleolithic art can be seen as embedded in the society that studies it. Over the last 20 years, the research attention given to women in Paleolithic societies has grown considerably, leading us to ask what could have been the roles of women in Paleolithic art. On what criteria could we base a determination of those roles or of other social identities that were likely part of the making and viewing of Paleolithic art?Thanks to our microscopic analysis of engravings, it is possible to identify the skill level and expertise of the artists and thus to address the question of apprenticeship and how these techniques were transmitted. We observe many similarities that allow us to group together various works of art, sometimes from very distant sites, which indicate a movement of ideas, objects, and people. Are we talking about “imitation”? How can we define an “invention” within a social context strongly bound by traditions?     

A Test of Ideal Free Distribution Predictions Using Targeted Survey and Excavation on California’s Northern Channel Islands

Using targeted survey, excavation, and radiocarbon dating, we assess the extent to which human settlement patterns on California’s northern Channel Islands fit predictions arising from the ideal free distribution (IFD): (1) people first established and expanded permanent settlements in the regions ranked high for environmental resource suitability; (2) as population grew, they settled in progressively lower ranked habitats; and (3) changes in the archaeological record associated with high population levels such as increases in faunal diversity and evenness in high-ranked habitats are coincident with the expansion to other areas. On Santa Rosa Island, the early permanent settlements were located in both high- and middle-ranked locations, with the most extensive settlement at the highest ranked locations and only isolated sites elsewhere. Settlement at a low-ranked habitat was confined to the late Holocene (after 3600 cal BP). Drought influenced the relative rank of different locations, which is an example of climate adding a temporal dimension to the model that episodically stimulated population movement and habitat abandonment. Because the IFD includes a wide range of cultural and environmental variables, it has the potential to be a central model for guiding archaeological analysis and targeted field research.     

“Seek and you Shall Find.” How the Analysis of Gendered Patterns in Archaeology can Create False Binaries: a Case Study from Durankulak

The gender structures of the communities of the Late Neolithic and Copper Age in South East Europe have been firmly placed in a binary system by past archaeological analysis. The analysis of cemetery remains has indicated that binaries are expressed through differences in body position and the types of artefacts placed in the grave. However, re-evaluation of evidence from Durankulak cemetery on the Bulgarian Black Sea coast demonstrates that such interpretations may result from the imposition of a modern Western understanding of gender as binary based on sex; these assumptions can lead to the exclusion of data which points to more complex and varied gender relationships. This paper briefly discusses the problems in starting archaeological analyses from an assumed binary in both sex and gender. It is argued that any approach that starts with this binary is likely to be misleading, and that large-scale data sets, such as cemeteries, should be investigated using multivariate statistical techniques to uncover a variety of horizontal and vertical social categories and roles, of which gender may be a part. It demonstrates that in the case of Durankulak, while there are gender differences, there was a great deal of more complexity than a simple male/female division. Some artefacts are exclusively associated with male burials, while female graves have less variety in their assemblages.     

Identifying Female in the Halaf: Prehistoric Agency and Modern Interpretations

This article considers ways that representations of anthropomorphic imagery in the form of figurines from prehistoric village communities have been interpreted and provides a new framework for analyzing figurines. It has been long suggested that prehistoric figurines should be interpreted as representations of female gendered qualities related to ritual, fertility, and motherhood combined into a concept called “mother goddess.” The impetus for the adoption of this interpretation and evidential association with prehistoric figurine assemblages and bound to binary gender is briefly critiqued. The methodology for studying figurine assemblages presented here utilizes typological, archaeological, and comparative analysis and is cognizant of inherent ambiguities in the object biographies of the full assemblage. This study applies this methodology to a corpus of figurines excavated from sixth millennium settlements associated with the Halaf material culture. This approach is then operationalized with case studies of figurines excavated from Domuztepe (Turkey) and Chagar Bazar (Syria) as examples of engagement with those who conceived, made, used, and discarded them. The Halaf figurine corpus is shown as nuanced, displaying sexual difference and humanness on a spectrum from overt to ambiguous. Considered as a whole, the Halaf corpus is shown to have had mundane and mutable use lives related to embodied identities entangled with culture and community, unconnected to gender binaries, ritual, fertility, or motherhood.     

Personal,Political, Pedagogic: Challenging the Binary Bind in Archaeological Teaching,Learning and Fieldwork

In this paper, we consider how we can undercut the various binaries of gender and sexuality in archaeological practice and particularly in our teaching. We argue that taking an assemblage theory approach enables us to look at the multiplicity of identities of those practicing archaeology as different and intersecting assemblages that bring one another into being through their connections at different scales. In particular, we examine how this approach can be applied to archaeological pedagogy and how this in turn enables us to move away from modern binary distinctions about sex and gender identities from the ‘bottom up’, fostering an approach in our students that will then go on to be developed in professional practice.     

Preparing for the afterlife: death,dying, and religious practice in eighteenth-century Puerto Rico

Every society possesses deeply rooted attitudes about death, yet much of what we know about the religious practices of ordinary people in colonial Latin America overlooks the way(s) in which people prepared for death and the afterlife. Sacramental records from eighteenth-century Puerto Rican communities provide insights into both religious elements and social aspects of death. The time period selected is important because new sensibilities toward death emerged in the late eighteenth century, with a movement away from elaborate status-affirming funerals toward the embracing of interiorized piety. This article uses sacramental records to examine reception of the last rites, funerary practices, and burial customs in eighteenth-century Puerto Rico. Three questions guide my inquiry: first, did reception of the last rites (penance, Eucharist, and anointing of the sick) decline in Puerto Rico and, if so, was this related to religious factors or demographic and socioeconomic ones as well; second, how successful were religious authorities in reshaping religious practices manifesting ‘baroque piety’ with a ‘more inward looking piety’: in peripheral areas of the Americas; and third, in what ways did burial customs reflect growing concern with the fear of Hell and time spent in purgatory?
