Northwest Mexico: The Prehistory of Sonora,Chihuahua, and Neighboring Areas

This article surveys research in Northwest Mexico (Sonora and Chihuahua), with an emphasis on the Early Agricultural period to the Late Prehistoric period. Middle range societies that are diverse in scale and organization characterize this region. Significant advancements in our understanding of these societies have been made in recent years, but substantial challenges remain in building interpretative frameworks that account for both regional diversity and incorporate macroscale interactions. Topics covered in this review include the adoption of agriculture, population movements, bases of social differentiation, and interactions between organizationally disparate groups. These issues demonstrate the relevance of the Northwest to research on the organization of middle range societies.     

An Informational Right to the City? Code,Content, Control,and the Urbanization of Information

Henri Lefebvre talked of the “right to the city” alongside a right to information. As the urban environment becomes increasingly layered by abstract digital representation, Lefebvre's broader theory warrants application to the digital age. Through considering what is entailed by the urbanization of information, this paper examines the problems and implications of any “informational right to the city”. In directing Tony Benn's five questions of power towards Google, arguably the world's most powerful mediator of information, this paper exposes processes that occur when geographic information is mediated by powerful digital monopolies. We argue that Google currently occupies a dominant share of any informational right to the city. In the spirit of Benn's final question—“How do we get rid of you?”—the paper seeks to apply post‐political theory in exploring a path to the possibility of more just information geographies.     

Capacity Design of Coupled RC Walls

Capacity design aims to ensure controlled ductile response of structures when subjected to earthquakes. This article investigates the performance of existing capacity design equations for reinforced concrete coupled walls and then proposes a new simplified capacity design method based on state-of-the-art knowledge. The new method is verified through a case study in which a set of 15 coupled walls are subject to nonlinear time-history analyses. The article includes examination of the maximum shear force in individual walls in relation to the total maximum shear force in the coupled wall system, and subsequently provides recommendations for design.     

Open-Air “Adena” Paired-Post Ritual Features in the Middle Ohio Valley: A New Interpretation

Circular paired-post structures have been recognized as a quintessential trait of the “Adena” concept. Although once thought restricted to ritual contexts beneath burial mounds, work over the last 30 years has identified several open-air structures in contexts apart from burial mounds or ditches. Uncluttered by overlapping features, open-air examples present a unique opportunity to document the initial roles played by these features. Currently, no unequivocal evidence for mortuary processing has been found directly associated with open-air paired-post structures. This fact calls into question the prevailing belief that most of these features were used to process, or prepare, the dead. Instead, a more reasonable interpretation is that these structures were involved in rituals minimally related to, or entirely devoid of, mortuary activity.     

On the Particularism of English Landscape Archaeology

The aim of this paper is to explore the question: why is the archaeology of English historic landscapes apparently so provincial? Inevitably the response must be that matters are more complex. In this paper, I examine the work of W. G. Hoskins, the “father of English landscape history,” and draw attention to: the complex way in which landscape is embedded in nationalism; the relations between locale, province, and nation; and the way wider tensions, in particular of colonialism are embedded within Hoskins's own discourse. In conclusion, I examine ways in which this problematic continues to structure enquiry into the English landscape today and to inhibit a genuinely international and comparative approach to historic landscapes.     

Intensification in the city centre: Barriers to implementation in Regina,Saskatchewan

As cities aim for more sustainable patterns of urbanization, intensification has emerged as a core planning strategy. In 2013, the City of Regina set new intensification targets: absorb 30% of annual population growth through intensification and add 10,000 residents to the city centre by 2035. In the decade since, implementation has been unsuccessful. This study explores the barriers to core area intensification in Regina by engaging with key informants through semi-structured interviews. Our findings identify the most significant barriers as soft market demand, a city centre that is unappealing as a residential context, insufficient political will, an absence of developers who specialize in core area intensification, and unfavourable development economics. These findings illustrate the unique challenges faced by mid-size Canadian cites in disrupting entrenched development patterns and driving development towards the downtown.     

A Minimum-Impact Method for Measuring Corrosion Rate of Steel-Hulled Shipwrecks in Seawater

Current research on USS Arizona is focused on a minimum-impact technique for calculating corrosion rate of the battleship's steel hull by analysing physical and chemical properties of marine encrustation covering the exposed hull. An equation is derived that allows concretion thickness, density, and total iron content to be used to calculate corrosion rate of steel hull plate.

Volcanic politics: Executive–legislative relations in Britain, 1997–2005

The parliamentary decline thesis overstates the dominance of the executive. The relationship between the executive and legislature is actually far more complex and balanced than is commonly recognised. After exploring recent developments in Australia and New Zealand, this article draws upon an audit of parliamentary modernisation in Britain since the election of New Labour in 1997 and suggests that a reforming parliament occurred during 2001–05 in which an executive with a majority of 166 was forced to acquiesce in the introduction of a raft of reform measures in the House of Commons that were designed to shift the balance of power. At the same time, the ‘transitional’ House of Lords displayed a new-found zeal and activism in a way that further frustrated the executive's control of parliament. This is not to overstate the degree of change: party loyalty remains the primary glue in the executive–legislative relationship and the executive remains dominant. However, it does suggest that in the British context the executive must still work within the limits and constraints of the parliamentary framework.
