After Gentrification: Social Mix,Settler Colonialism,and Cruel Optimism in the Transformation of Neighbourhood Space

Social mix policies have emerged as a prominent mechanism to legitimate neighbourhood redevelopment efforts across the US. Despite integrationist rhetoric, results often disabuse marginalised communities of their claims to the city. This paper employs a hybrid spatio‐temporal analysis at the intersection of political‐economic theories of gentrification and post‐colonial and Black geographies literatures to examine underlying cultural logics and affective experiences animating such processes of neighbourhood transformation, contestation, and succession. Reflecting on 15 years of experience researching Over‐the‐Rhine (OTR), Cincinnati, we contribute a stylised distinction between the foundational, mature, and ongoing legacies of urban settler colonial relations. Our account discloses the power geometries shaping neighbourhood space by illustrating the impact of the discourses, tactics, and strategies employed by pro‐development actors and neighbourhood activists as OTR's socio‐political landscape shifted over time. In conclusion, we engage the thorny questions these dynamics raise surrounding how inner‐city neighbourhoods are theorised and struggled over after gentrification.     

The SpatialARMED Framework: Handling Complex Spatial Components in Spatial Association Rule Mining

Recent research has identified spatial association rule (SAR) mining as a promising technique for geographic pattern mining and knowledge discovery. Nevertheless, important spatial components embedded in the studied phenomenon, in particular complex spatial functional relations such as neighborhood effects and spatial spillover effects have largely been neglected. This article unravels this specific problem to enhance the effective application of SAR mining practices in spatial data analytics. The main discussion focuses on the specification of complex spatial components by means of spatial dependence properties of the data and on how to integrate them in the process of SAR mining. A comprehensive framework dubbed SpatialARMED is proposed for the effective extraction of spatial patterns. The framework is then showcased through its application to crime analysis.     

Archaeological Assessment of Second World War Anti‐Torpedo Close Protection Pontoons in Scapa Flow,Orkney

This paper presents the outcomes of sidescan sonar and archaeological diving surveys in 2015 of two wrecked vessels located off Flotta Island, Orkney, North Scotland. Archival research indicates these are the remains of Anti‐Torpedo Close Protection Pontoons (ATCPP), an experimental protection device used for close protection of naval vessels at anchor in Scapa Flow from attack by aircraft‐launch torpedoes. The pontoons were only in operation in Scapa Flow for 13 months (March 1941–April 1942) and few were brought into service. As such they represent a rare heritage resource, for which very little is known about their operation.     

Old Oslo

DURING an excavation outside the NW. corner of the defences of Winchester, Hants., an object was discovered which careful conservation proved to be an early medieval burse-reliquary. It has a wooden core, to which are tacked thin, gilt copper-alloy metal sheets, with embossed decoration. The context of the reliquary suggests its loss in the late 9th or early 10th century, and its art-historical associations indicate that it had been made at some time in the previous hundred years. It is the first early medieval reliquary of this type to have been found in England.

The first European representative of the South American family Xenopteraidae (Insecta: Megasecoptera) discovered in the Guadalupian of Lodève (France)

NEL, A., LAPEYRIE, J. & GARROUSTE, R. May 6 2019. The first European representative of the South American family Xenopteraidae (Insecta: Megasecoptera) discovered in the Guadalupian of Lodève (France). Alcheringa 43, 436–440. ISSN 0311-5518.

A new genus, Sinitshenkovae gen. nov., is described, comprising the Carboniferous species Sinitshenkovae hueneckeni (Pinto & Pinto de Ornellas, 1978 Pinto, I.D. & Pinto de Ornellas, L., 1978. Upper Carboniferous insects from Argentina. 1. Familia Diaphanopteridae (Megasecopteroidea). Pesquisas (Zoologiat) 10, 87–95. [Google Scholar]) comb. nov. from South America and new Guadalupian species S. gallica sp. nov. from France. These two species are attributed to the Paleozoic South American family Xenopteraidae, a previously monospecific family only containing Xenoptera riojaensis Pinto, 1986 Pinto, I.D., 1986. Carboniferous insects from Argentina. 3. Family Xenopteridae Pinto nov. fam. (Megasecoptera). Pesquisas (Zoologia) 18, 23–29. [Google Scholar]. Sinitshenkovae gallica sp. nov. is therefore the youngest representative of this family and the only record outside South America, which suggests that our current knowledge of the palaeobiogeography of Permian and Carboniferous insects remains incomplete.

Covert and Overt Activism: Christianity in 1950s Coastal China

The phenomenal growth of Catholic and Protestant churches-both officially-registered Three-Self patriotic churches and unofficial house churches-in China has drawn attention to the underlying dynamics of Chinese Christianity.This article draws on archival research and ethnographic findings to investigate the interactions between the officials and Christians in the coastal regions of Shantou (Guangdong province) and Wenzhou (Zhejiang province) during the 1950s and 1960s.The Chaozhou-speaking Catholics,Baptists and Presbyterians in Shantou succeeded in transcending sectarian boundaries and helped each other to cope with political pressure.The Seventh-day Adventists in Wenzhou did likewise by organizing clandestine house gatherings with other Protestants.They held onto their faith,continued their worship activities on Saturday,and maintained a distinct,though not independent,identity under the broad spectrum of Protestantism.These local stories show that as a collective force,Chinese Christians not only employed a variety of tactics to help each other but also reinvented congregational,kinship and cross-regional networks as conduits for pursuing religious goals.Their covert and overt activism highlight the need to combine archival research and fieldwork to assess the revival of Christianity in present-day China.
