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.     

Asian migration to Australia: Changing trends and implications

International migration between Asia and Australia has undergone profound change in the last two decades. This paper outlines the major changes which have occurred in this movement. The proportion of Australia's resident population born in Asia has increased from 1.1 % in 1976 to 5.5 % in 2001. Asians now make up more than a third of new settlers to Australia but there has been an increased diversity in the flow of Asian settlers to Australia as well as the substantial increase in numbers. Australian international migration has entered a new era since the mid‐1990s with a greatly increased flow of temporary workers to Australia. The inflow of these workers is less dominated by Asia‐born people than is the permanent flow except for student migration. There is also an increasing flow of movers from Australia to Asia. Much current knowledge and research remain focused on Asian permanent settlement in Australia. While this is important and worthwhile, there is a need to broaden the work to encompass the full range of population movements between Asia and Australia if the impact of international migration is to be adequately assessed.

Re‐writing the ‘book of blots’: Critical reflections on histories of technological ‘failure’

Abstract

Although an interest in technological ‘failure’ has become prominent in recent history of technology, historians have not always clearly articulated the presuppositions of attributing ‘failure’ to technology. This paper undertakes a critical examination of two main historiographies of ‘failure’: ‘failure’ as categorization of ‘pathological’ technologies that clearly demarcates them from ‘successes’, and ‘failure’ as a mundane and inevitable prerequisite of subsequent ‘success’. To reconcile these divergent analyses, this paper argues that historians should not treat ‘failure’ as residing in the technology itself. It is rather a matter of imputation according to socially‐embedded criteria of what constitutes success and failure. Accordingly judgements of ‘failure’ are prone to interpretive flexibility in a manner that is not necessarily settled by any process of ‘closure.’ I will argue that any ‘failure’ of technologies should be located in the socio‐technical relations of usage, especially in the expectations, skills and resources of human users. The moral irony of attributing responsibility for ‘failure’ to technologies themselves rather than to humans users will thereby be highlighted.     

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.     

From dates to demography in later prehistoric Ireland? Experimental approaches to the meta-analysis of large C data-sets

We present a series of iterative methods to examine the problems associated with summed probability functions (SPFs) based on archaeological radiocarbon data. As a case study we use an SPF generated from a substantial radiocarbon data-set from the Irish Later Bronze and Iron Ages. We use simple numerical methods to show that real patterns can be deciphered from SPFs that can be used to trace and evaluate patterns of change. However, our results suggest that SPFs should not be used as a simple index of past human activity.     

Communism,Heritage and Tourism in East Asia

This study examines the linkages which connect Communism, heritage and tourism with reference to selected East Asian states which are governed by Communist regimes or have recent experience of Communist rule. Aspects of the heritage of Communism are seen to be of interest to tourists, but related visitor attractions also have a wider social and political significance and illustrate how tourism can be employed as a hegemonic tool and propaganda vehicle. Heritage, including that of Communism itself, thus serves as economic, social and political capital within a Communist context where the defining characteristics of government give rise to a distinctive relationship between political systems, heritage and tourism.
