New insights about the construction and use of shell mounds from the geochemical analysis of mollusks: an example from the greater San Francisco Bay

A new method developed by Schweikhardt et al. (2011) for the geochemical analysis of bay mussels is applicable (when combined with radiocarbon assessments) for examining the seasonal construction patterns and growth cycles of coastal mound sites over time. Ideally suited for the analysis of mollusk fragments in museum collections, this method allows archaeologists to evaluate divergent models about the functions of mound sites, as well as the mobility practices and social organizations of the mound builders. In this case study, the method is employed to examine two adjacent mounds (Ellis Landing, Brooks Island) in the San Francisco Bay Area, California to assess whether their occupants may have participated in a broader multi-site community dating to the Late Period (1100–250 BP).     

Historicising Agency

Why has ‘agency’ been such a tenacious concept in historical scholarship on women and gender, and what have been the consequences on this tenacity? This essay tackles these questions and proposes, through a brief examination of the history of skin lighteners in South Africa and beyond, how agency might be pushed in more surprising, more analytically productive directions. Too often agency slips from being a conceptual tool or starting point to a concluding argument. For example, in my subfield of African women's and gender history, statements like ‘African women had agency’ can stand as the impoverished punch lines of empirically rich studies. Consideration of Walter Johnson's 2003 essay ‘On Agency’ highlights the intellectual and political imperatives of 1970s Marxist and feminist social history that placed agency at centre stage. This essay examines why, more than a decade after Johnson's critique, agency endures as a ‘safety’ argument for reasons related to representational politics, research methodologies and the circumscribed imagination of intellectual gatekeepers. It argues that we should move beyond agency as argument by attending to the multiple concerns and desires – some intentional, others not – that animate human actions, including contentious gendered practices, and by examining how different historical actors have themselves understood agency. Agency has a history. By acknowledging and tracing that history, we will be better able to discern the usefulness and limits of agency for our own analyses.     

Out-of-Plane Seismic Response of Unreinforced Masonry Walls: Conceptual Discussion,Research Needs,and Modeling Issues

ABSTRACT

Modeling unreinforced masonry walls, subjected to seismic loads applied normal to their plane, has received much attention in the past. Yet, there is a general lack of conformance with regard to what aspects of seismic response a computational model should reflect. Boundary conditions are certainly an important aspect, as the response can involve two-way bending or just one-way bending and, in the second case, along vertical or horizontal directions. In this respect, flexural restraint of wall intersections can be significant in addition to size and placement of openings. Moreover, in-plane damage can modify the boundary conditions and the overall out-of-plane performance. Proper modeling of actions is also relevant, as they can be a result of distortions imposed upon wall elements and/or inertial forces along the span of a wall. Axial forces can markedly affect the out-of-plane response of the wall, particularly vertical compressive forces, which can enhance out-of-plane strength. The outcome of static verifications can be more conservative than that of dynamic analyses, but the latter are much more complex to carry out. These topics are discussed with reference to previous research, observations in the field and in the laboratory, as well as numerical analyses on three-dimensional models.     

Architectural Energetics, Ancient Monuments, and Operations Management

Architectural energetics, subsumed within replicative archaeology, provides a means through which buildings are translated into labor-time estimates. To date, the majority of architectural energetics analyses have generated comparative measures of architectural costs, equating these with a vertical structure of political power and authority within and among societies. The present analysis expands the application of architectural energetics by subjecting construction labor costs to an analysis based on concepts central to the Theory of Constraints, which is widely applied in modern operations management. This modeling generates a hypothetical set of behavioral patterns performed by general laborers within a construction project and explicates a method which allows further exploration into the question of labor organization (i.e., allocation and articulation of workers), as well as perhaps other economic organization, in an archaeological context. The case example is Structure 10L-22, a large Mayan palace at the site of Copan, Honduras.     

Fighting for the Afterlife: Spiritists, Catholics, and Popular Religion in Nineteenth-Century France

This article examines the position of nineteenth-century French spiritism in relation to the Catholic Church. Spiritism offered an alternative "religion" to French Catholics dissatisfied with the church's traditionalism in a modernizing world. I begin by describing the spiritists' position on Catholic dogma and the movement's place as an urban popular religion. Spiritist critiques of heaven and hell incorporated liberal and republican values, thus making it appealing to these groups who were often hostile to the church. I move next to conflicts between the adversaries. Spiritists, unfettered by dogma or even logic in some cases, freely incorporated the supernatural into the nineteenth-century acceptance of Enlightenment values such as reason and science. The church, unable to deny the reality of supernatural phenomena claimed by the spiritists, limited itself to asserting the devil's hand in these phenomena. It thus could not fully address the challenge of spiritism. Spiritism as a popular religion complicates the assumption by many folklorists regarding the disappearance of popular beliefs in the face of the modern. The article concludes with a call to modify these theories in order to understand an evolving, often urban, popular culture which integrated "tradition" and "modernity" and continually created new forms of the marvellous.
