Opacifiers in Late Bronze Age glasses: the use of ToF-SIMS to identify raw ingredients and production techniques

Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) is applied to the study of four samples of opaque glass of Late Bronze Age date. The technique is uniquely capable of identifying compositional heterogeneity at a sub-micron resolution within the crystalline opacifiers dispersed through homogeneous glass matrices. It is shown that this provides crucial information on the possible raw ingredients of the opacifying inclusions used, and has the potential for highlighting regional variations in the production technology involved in creating different colours of opaque glass.     

The early history of the neuroscience of attention-deficit/hyperactivity disorder

Research on the neurobiology and pharmacotherapy of attention-deficit/hyperactivity disorder (ADHD) has grown exponentially since 1980. A reasonable question is whether this research has improved our understanding and treatment of ADHD. This article describes relevant developments that took place roughly between 1900 and 1970. During this time, the efficacy of stimulant therapy for the disorder was established and the symptoms of ADHD were linked to many possible nervous system disorders including in the brain-stem, reticular formation, diencephalon, basal ganglia, frontal lobes, and cortex. In 1970, the catecholamine hypothesis of ADHD was proposed. It is concluded that early theories about the neurobiologic basis of ADHD anticipated core ideas of modern theory.     

Provenance of Zhangzhou export blue-and-white and its clay source

Trace element compositions of 25 shards of Chinese Late Ming export blue-and-white porcelain from Zhangzhou and Jingdezhen kilns are analysed by Inductively Coupled Plasma Mass Spectrometry. Principle components analysis and REE distribution curves are used to establish method for provenance unknown Chinese export blue-and-white porcelain which may have originated from Zhangzhou or Jingdezhen kilns. By matching the REE distribution curves of Zhangzhou kiln samples and parent rocks of the possible clay sources used to make Zhangzhou blue-and-white, and comparing it with previous results of geological, geochemical and archaeological researches, the clay used for producing Zhangzhou export blue-and-white has been identified as having been collected from the weathered shells of a nearby potassium feldspar miarolitic granite outcrop.     

Early parenting and the urban experience: risk,community, play and embodiment in an East London neighbourhood

This article will critically examine theories of risk – referred to in this article as ‘pro-risk’ – as applied to parenting cultures in the UK through a case study of early years parenting, based in Walhamstow, East London. Common to all of these theories is an assertion that children are over-parented – a product of economic, social and cultural changes such as the decline of community as well as theories of child-centred parenting. Through the close examination of two examples where risk and community were contested, the article will argue that missing from these theories is an understanding of the embodiments of early years parenting, which underpin the way that parents handle the tensions between risk and development. Further, that parents sought to militate against isolation and the decline of community through local parenting networks.     

Reconceptualizing Resistance: Residuals of the State and Democratic Radical Pluralism

Abstract: Arguing that resistance to the state is too narrow a conceptualization of a political project that challenges neoliberalism, we posit that there are latent, residual apparatuses of the state which can be activated as part of a systematic progressive politics. We examine Massachusetts’“Dover amendment”, a legal framework which governs group home siting throughout the state. Dover offers a powerful tool with which to resist a neoliberal socio‐spatial agenda, though it has been underutilized toward enabling an alternative landscape. We analyze how and why Dover has often remained latent as a tool for socio‐spatial resistance, and consider a provocative case in Framingham, Massachusetts that suggests how residual state apparatuses may be leveraged in support of an explicitly resistive, progressive agenda.     

A Core-Periphery GIS Model of the Historical Growth and Spread of Islam in China

Abstract

This study presents the methodology and results of a core-periphery GIS model of the historical growth and spread of Islam in China based on a dataset of 1,774 mosques. These sites were organized into data subsets according to their founding dates during five major dynastic periods in Chinese history: Tang/Song, Yuan, Ming, Qing, and Republican. Core areas were identified and mapped based on where mosques clustered during each period. North China was the paramount core region in all periods. Not until the late Qing and Republican periods did the Northwest and Yunnan compare with North China, while coastal China never developed into a core area.
