MAGNETIC SUSCEPTIBILITY THICKNESS CORRECTIONS FOR SMALL ARTEFACTS AND COMMENTS ON THE EFFECTS OF‘BACKGROUND’MATERIALS*

Correction factors for magnetic susceptibility measurements on thin (<c. 50 mm thick > artefacts have been determined experimentally for a KT‐5 Exploranium G S. instrument using prepared blocks of Whin Sill dolerite. The cor rection factor is large (> 1.4) for samples less than 10mm thick, and reduces to 1 01 for samples of 50mm thickness. Measurements on thin samples can also be affected by the backing or substrate material on which they are measured. ‘Background’material, for example, soil or plaster, can contribute significantly to recorded measurements on artefacts, particularly for thin artefacts with low susceptibilities     

Three's a Crowd?: Government, Owners, and Workers during the Nationalization of the British Coalmining Industry 1945-47

The passing of the coalmining industry into public ownershipon 1 January 1947 should have been an occasion for rejoicingby the Labour Party and its supporters, yet celebrations weremuted by the looming shadow of critical coal shortages Despitethis concurrence of nationalization and coal crisis, littleattention has been focused on possible linkages between thetwo events. More generally, scant consideration has been givento the question of what happened to the industry when facedwith nationalization. This article's principal argument is thatthe fuel crisis was rooted not (as other historians have argued)in the atrocious weather, but in the very process of nationalization—or,rather in the combination of a lack of preparation for publicownership and (even more importantly) in the preoccupation withnationalization at the expense of the ‘stabilization’of the industry before entering the uncharted waters of publicownership. The chief conclusion is that during the run-up toVesting Day neither miners nor owners had any substantial incentiveto improve industrial productivity and output The period wasat best a standstill, and in many ways—as the crisis indicated—wastedmonths that a fuel-starved Britain could ill afford ^*This article is based on my MA thesis, ‘Fresh Start orFalse Dawn⁷ the coalmining Industry and Nationalisation, 1945–7'I would like to thank my supervisors, Ranald Midne and PhilipWilliamson for their continued support, and also David Howelland the referees of Twentieth Century British History for theirvaluable comments on earlier drafts of this work.     

The new resource politics: can Australia and South Africa accommodate China?

The material transformation of the Chinese economy is forcing a concomitant process of political adjustment—and not just in China. Other states are being forced to accommodate the ‘rise of China’. In this context, this article first presents a comparative analysis of China's impact on two countries, Australia and South Africa, which have little in common other than a wealth of natural resources and a possible status as middle powers; this is a particularly useful exercise because these states are geographically distant and have very different political structures and general developmental histories. Second, the authors consider how China's bilateral ties look from a Chinese perspective in these two very different relationships. Such an analysis serves as a reminder that resource dependency is a two‐way street. The article argues that underlying material realities are constraining and to some extent determining the domestic and foreign policies of three very different states that otherwise have little in common.     

The UN Arms Trade Treaty: arms export controls,the human security agenda and the lessons of history

The UN conference to negotiate an Arms Trade Treaty (ATT) concluded on 27 July 2012 without reaching consensus on the text of a draft treaty and saw both the US and Russia calling for more time to negotiate. The ATT process marks the latest in a series of attempts to insert human security concerns into arms export controls. The setback in July raises questions about the current level of international support for the human security agenda, as well as the relative power of different actors to shape global governance structures. This article locates the ATT negotiations in the broader history of multilateral efforts to regulate the international arms trade, from the 1890 Brussels Act to post‐Cold War initiatives. The historical record shows that such efforts are more likely to succeed if they are negotiated or imposed by major arms exporters. The introduction of human security concerns, as well as the merging of export control and arms control agendas, went some way towards reversing this trend. In particular, it created a broad international coalition of supportive states and NGOs from the global North and South. Yet disagreements over the purpose of an ATT remained. The draft ATT included human security provisions, but China, Russia, the US and a number of emerging powers ensured that state security considerations remained paramount in decision‐making on arms exports. The US was the first major actor to announce its unwillingness to sign the draft ATT in July 2012 and two alternative interpretations of US actions are considered. The article concludes by considering the options available to supporters of the ATT process following the 2012 conference and examines the notion that the ATT campaign has become an initiative ‘out of its time’, one that might have had success in the 1990s but not in current circumstances.     

Unity and Exclusion in the Roman Catholic Priesthood: Explaining the Creation of the National Council of Priests of Australia

The National Council of Priests of Australia (NCP) was created in Sydney in September 1971 and continues to exist today. The organization has undergone some significant changes since its beginnings. It moved, for instance, from representation by delegates to direct membership in the mid‐1970s, which made it unique among other national associations of priests that were sponsored by bishops. Since its beginnings, deciding whether or not to extend membership to ordained men no longer in active ministry has proved to be a vexing issue within the NCP. It has shaped the organization's culture as much as those who qualify to belong. This article explains the significance of the NCP membership criteria and looks to some of the long‐term and short‐term influences on its creation.     

Conceptual and practical issues in the detection of local disease clusters: a study of mortality in Hamilton, Ontario

Recent advances in local spatial statistics and operational computing capacity have led to growing interest in the detection of disease clusters for public health surveillance and for improving understanding of disease pathogenesis. Although conceptual reviews and applied examples have appeared in the literature, few studies have addressed the connection between conceptual and practical issues that confront researchers interested in using local statistics to detect disease clusters. Here we review recent literature on the use of local statistics for cluster assessment and focus on the practical issue of assigning correct geographic coordinates. The process of assigning geographic coordinates to an address or postal code, known as ‘geocoding’, is a necessary step in conducting smallarea health analyses. With a study of mortality data from Hamilton, Ontario, we illustrate inaccuracies that may be encountered when using Statistics Canada postal code conversion files. Using the Moran's I and Getis‐Ord Gi and Gi* local spatial statistics to identify significant mortality clusters or ‘hot spots’, we demonstrate that small geocoding errors, even those that affect less than one percent of a total dataset, can have a discernible impact on analytic results. To assist other researchers, we supply guidelines to minimize error introduced by geocoding. These results emphasize the importance of accurate geocoding in local health analyses. Les avancées récentes en statistiques spatiales localisées et en capacité informatique opérationnelle ont conduit à un intérêt croissant dans la détection de foyers de maladies pour fins de surveillance de santé publique, et dans l'approfondissement de la compréhension de leur pathogénèse. Bien que des revues conceptuelles et des exemples concrets aient été publiés dans la littérature, peu d'études ont adressé le lien entre les problèmes conceptuels et pratiques auxquels sont confrontés les chercheurs intéressés à utiliser les statistiques locales pour détecter les foyers de maladies. Nous revoyons ici la littérature récente sur l'utilisation de statistiques locales dans l'évaluation de foyers et focalisons sur le problème pratique d'assigner des coordonnées géographiques correctes. Le procédé d'assigner des coordonnées géographiques à une adresse ou à un code postal, nommé‘géocodage’, est une étape nécessaire dans la conduite d'analyses de santéà petite échelle. À l'aide d'une étude sur des données de mortalitéà Hamilton, en Ontario, nous illustrons que des inexactitudes peuvent être rencontrées lorsque les fichiers de codes postaux et de conversion de Statistique Canada sont utilisés. En utilisant les statistiques spatiales localisées I de Moran, Gi and Gi* de Getis et Ord pour identifier des foyers de mortalité significatifs ou des ‘points chauds’, nous démontrons que de petites erreurs de géocodage, même celles n'affectant moins qu'un pour cent de la base de données, peuvent avoir un impact discernable sur les résultats analytiques. Afin d'aider d'autres chercheurs, nous fournissons des recommandations pour minimiser les erreurs introduites par le géocodage. Ces résultats soulignent l'importance d'un géocodage exact dans les analyses de santé locale.
