Building Local Governance: Participation and Elite Capture in Slum‐upgrading in Kenya

Community and democratic participation are still an essential component of current mainstream development interventions. However, elite capture seriously undermines the outcomes of development projects. This article analyses the effects on (in)equality of the implementation of policies that are technically participatory, in the context of an internationally‐funded urban development programme in Nairobi, which was implemented in the aftermath of the post‐election violence of 2007–2008. Ethnographic data reveal how the institutionalization of pre‐existing power imbalances between landlords and tenants is accomplished through the creation of structures of community governance and ‘participatory enumeration’. The article concludes that without the resources to challenge powerful interests within the settlement, the programme is likely to worsen the condition of a large section of the residents. In the context of strong pre‐existing inequalities and conflict, participation needs careful management and firm external agency to achieve genuine social transformation.     

Displacement-Based Design of an Energy Dissipating System for Seismic Upgrading of Existing Masonry Structures

A displacement-based method for the design of an energy dissipating system is proposed in this article. The device, which is composed of added concrete walls equipped with hysteretic Added Damping and Stiffness (ADAS) dampers, is aimed at upgrading the seismic behavior of existing masonry structures. The design method is based upon a simplified model of the overall structure-dissipating system. The proposed displacement-based design procedure was tested by means of inelastic response-time history analyses considering different masonry structures. The results of the analyses were compared with the seismic behavior expected from the design.     

Mesolithic Site Formation and Palaeoenvironment Along the White Nile (Central Sudan)

The Mesolithic period represents a key stage in the human history of Sudan, but its complexity is not yet fully understood. Since the beginning of prehistoric research in this region, efforts were made to understand Mesolithic site formation processes and post-depositional disturbances. Responsibility for the destruction of most Mesolithic sites’ deposits rests mainly on later use of the ancient mound-like settlements as burial places by Meroitic and post-Meroitic people. Excavations at several sites in the El Salha and Al Khiday areas (White Nile, south of Omdurman) have provided recent progress in our knowledge of Mesolithic living structures in their palaeoenvironmental contexts. Detailed stratigraphic and geoarchaeological investigations enabled us to distinguish, within the sequences identified at excavated mounds, the existence of basal archaeological strata still in situ that had remained unaffected by subsequent anthropogenic disturbances and to understand the functional aspects of several archaeological features associated with Mesolithic living floors. This offers the opportunity to reassess the Mesolithic cultural sequence in the region and reconsider some statements on the economic and social aspects of Mesolithic life and landscape exploitation strategies.     

Application of a new typological approach to classifying denticulate and notched tools: the study of two Mousterian lithic assemblages

Identifying tools by means of morphological attributes are widely used in lithic studies to categorize retouched artifacts from different archaeological periods. This procedure has facilitated the exchange of information between separate researchers and has improved the comparison of different assemblages. In these classifications, denticulates and notched tools have been regularly interpreted as analogues and chronologically unvaried in different and vast territories. Based on the definitions developed by Bordes, the denticulate category has become a catchall for any kind of tool bearing concavities. In this paper a new quantitative approach to the classification of denticulates and notched tools is proposed. The new methodology is based on measuring the length of notches and their distribution on the perimeter of the blank. Analyzing the lithic series of the Abric Romaní rock-shelter (Spain) and Grotta Maggiore di San Bernardino (Italy) led to the identification of 11 redundant forms: eight denticulates and three notched tools. Moreover, the application of Kuhn’s Geometric Index of Unifacial Reduction brought local manufacturing trends to light, calling into question the presumed geographical uniformity of these categories of artifacts.     

The function of Chalcolithic metalwork in Italy: an assessment based on use-wear analysis

This paper presents results of the use-wear analysis of Chalcolithic copper-base metalwork from the Italian peninsula. Previous research led to contrasting scholarly opinions regarding the function of early metal axes, daggers and halberds from this region. Whilst some authors interpreted these objects as utilitarian tools and weapons, others saw them as symbolic signifiers of social status and personhood. The analysis conducted here shows that this is a false dichotomy as all classes of metalwork seem to embody to some extent both utilitarian and non-utilitarian values. In particular, axes were primarily used for woodworking and other practical tasks, but were mostly withdrawn from circulation when still usable. This suggests that deposition practices bore a loose relationship, if any, with the functional value of the tools. Daggers were employed in a range of symbolically charged practices that left little wear on cutting edges. These probably included the sacrificial slaughtering and skinning of large animals such as cattle and horses. Halberds were utilised as weapons in champion’s duels in which display of combative skills and prowess would have been far more important than killing the opponent. This explains the relatively low rate of damaged blades in the record. Regardless of their practical function in lifetime settings, these objects were all similarly employed in burial to reproduce core social values such as gender and age. Importantly, this study contributes to debunking undemonstrated assumptions concerning the function of early metalwork in European prehistory. It also defines a replicable analytical protocol for the use-wear analysis of ancient copper-alloy artefacts.     

A comment on Steele’s (2010) “radiocarbon dates as data: quantitative strategies for estimating colonization front speeds and event densities”

We show that Steele’s (2010) criticisms of Hamilton and Buchanan (2007) and Buchanan et al. (2008) do not hold water and demonstrate that his re-analyses of Hamilton and Buchanan’s (2007) and Buchanan et al'.s (2008) datasets are flawed. In the process, we highlight some important issues for researchers interested in using radiocarbon dates to reconstruct population movements and demography. Most notably, we explain why OLS regression is preferable to RMA regression when estimating diffusion velocity, and demonstrate that the summed probability distributions yielded by CalPal are more reliable as guides to past demographic change than those produced by Calib and OxCal.     

Revealed by Waves: A Stratigraphic,Palaeoecological, and Dendrochronological Investigation of a Prehistoric Oak Timber and Intertidal Peats,Bay of Ireland,West Mainland,Orkney

An oak timber was discovered in 2013 within intertidal peats at the Bay of Ireland, Stenness, Orkney, representing a unique archaeological find. Subsequent excavation and rescue of the timber took place in 2014 to investigate its stratigraphical relationship before further eroding. Dendrochronological and morphological study identified the timber as a possible radially split log, c. 150 years of age when felled. No dendrochronological match was possible, and a wiggle-match date obtained provided a Later Mesolithic felling date of 4410–4325 cal BC. This timber is the first and only evidence so far for the use of oak in Mesolithic Orkney. The timber is significant palaeoecologically, suggesting oak may have been indigenous to Orkney. This adds to a growing argument for the existence of areas of “true woodland”. Pollen evidence shows the timber was deposited within reedswamp, fringed by willow-birch carr-woodland, with oak unlikely to have been growing in the immediate location. High microscopic and macroscopic charcoal values indicate Later Mesolithic communities exerted influence on this wetland using burning as a tool for landscape modification. It is unknown what the timber represents; it may have been for construction purposes or as a marker/possible landing place showing the path to the Loch of Stenness.     

Contribution of strontium to the human diet from querns and millstones: an experiment in digestive strontium isotope uptake

The question of whether rock grit ingested unintentionally from querns, metates or millstones, or deliberately through pica or geophagy, is bioaccessible in the human gut has not been addressed in archaeological strontium (Sr) isotope studies. This study employed the unified bioaccessibility method and determined that ingested rock grit can provide bioaccessible ⁸⁷Sr/⁸⁶Sr, but that unintentional consumption is unlikely to constitute > 1% of the diet (by mass) and will not significantly change, that is, by > 0.001, human skeletal ⁸⁷Sr/⁸⁶Sr. The use of locally or non‐locally sourced querns or millstones will not affect the interpretation of archaeological human ⁸⁷Sr/⁸⁶Sr values in Britain.     

“Removes All Obstacles”: Abortifacients in Nineteenth-Century Toronto and Beyond

Exploring the biographies of small artifacts from archaeological contexts is an endeavour that can expose unrealized or forgotten historical and cultural meaning at local, regional, national, and international levels. The recovery of a small glass bottle embossed with the name “Sir J. Clarke’s Female Pills” from a site in Toronto has drawn together the production history and advertising during the nineteenth century of a patent medicine product classed as an abortifacient. Furthermore, it connects the history of women’s health and fertility rights to the social and economic motivations influencing control over family planning.
