The Potential of Tree Rings in Eucalyptus pauciflora for Climatological and Hydrological Reconstruction

We investigate the causes of variability in a tree‐ring chronology comprising data from Eucalyptus pauciflora Sieb. Ex. Spreng. at the alpine treeline on the Kosciuszko Plateau in New South Wales, Australia. Following verification of crossdating in a subset of the available data, we found that ring width correlates significantly with net radiation, precipitation and mean minimum and maximum air temperature during the preceding winter and spring of the growing season. Our results for spring are consistent with the impact of climate on tree growth in alpine woodlands reported in previous studies. Analyses of snow‐depth data revealed negative correlations with ring width throughout winter and spring. Our results indicate that low temperature and high precipitation during winter negatively affect the growth of E. pauciflora by prolonging spring snow cover. Ring width also correlates significantly with an index of soil dryness and flow in rivers with their headwaters in the Kosciuszko plateau. Given the apparent sensitivity of our chronology to climate and snow conditions, our results suggest that tree‐ring chronologies comprising data from E. pauciflora at the alpine treeline have potential for climatological and hydrological reconstruction in southeast Australia.     

A Call to Action: New Party Candidates and the 1931 General Election*

Sir Oswald Mosley established his New Party in early 1931. It proposed to cut across the party and class divides, with the objective of providing a ‘national’ solution to the economic crisis of the time. According to Mosley, the ‘old parties’– meaning the Labour, Conservative and Liberal Parties – had revealed themselves unable to adapt to the post‐war age. In their place, he argued, a modern organisation, based on youth, vitality and a scientifically reasoned economic plan, was needed to save Britain from terminal decline. Few heeded his call, and the party ultimately paved the way for the British Union of Fascists to emerge in 1932. Nevertheless, the New Party fought the general election of 1931, offering an unsuccessful but suitably intriguing challenge to the National coalition and Labour Party. This article will assess the New Party's election campaign, concentrating on those who briefly rallied to Mosley's appeal only to fall foul of the ballot box. In other words, it provides a case study of those who contributed to a dramatic electoral failure, and traces a significant stage along Mosley's journey to fascism.     

MATCHING PAST AND PRESENT CERAMIC PRODUCTION IN THE BANDA AREA (GHANA): IMPROVING THE ANALYTICAL PERFORMANCE OF NEUTRON ACTIVATION ANALYSIS IN ARCHAEOLOGY USING MULTIVARIATE ANALYSIS TECHNIQUES*

The transfer of advances in chemometrics into archaeometric research opens up a wide range of new application possibilities in this rapidly developing field. Neutron activation analysis (NAA) of ceramic samples from the Banda Traditional Area (west‐central Ghana) combined with chemometrics allowed us to establish a link between current and ancient systems of ceramics production in the historic settlements of Kuulo Kataa and Makala Kataa. Principal component analysis (PCA) and the soft independent modelling of class analogy (SIMCA) method were applied to the Das Dores Cruz data set in order to unequivocally determine the geographical origin of the diverse archaeological samples. After global autoscaling pretreatment, PCA analysis showed a clear difference between samples from different locations. The classification models obtained by SIMCA showed a classification ability of 100% and a prediction ability of 97.7%, with a mean sensitivity of 84% and a specificity of 100% for the three categories. The application of SIMCA showed that some NAA variables (elements) were more important than others in terms of geographical classification. With the class models that we obtained, we were able to determine the origin of the ancient remains. SIMCA has proved to be a powerful technique for the class modelling of archaeological data.     

Scaling‐Up,Scaling‐Down,and Scaling‐Out: Local Planning Strategies for Sea‐Level Rise in New South Wales,Australia

Globally, sea‐level rise is expected to impact on many coastal regions and settlements. While mitigation of global greenhouse gas emissions remains an important task, adaptation is now seen as a critical component of the policy equation. Local government is a key player in adaptation planning and managing risk through their mandated role in land use planning and development control. Yet, managing the predicted impacts of climate change is proving to be a complex and difficult task for planners and policy makers. This paper reports on a case of local government deliberation on possible planning responses to address future sea‐level rise impacts in New South Wales, Australia. Using structured, expert opinion of planners and other technical experts engaged in a collaborative network in the Sydney region, we explore the feasibility of implementing planning and policy measures at the local and regional scales to respond to inundation risk as a result of sea‐level rise and storm surge events. Our research shows how local governments employ specific scale‐oriented strategies to engage private and public actors at different scales to manage legal, financial, and technical risks in coastal adaptation.     

RETHINKING the GREAT REBUILDING

Summary: This paper traces the history of the debate over the 'Great Rebuilding'of rural England, argued by W. G. Hoskins to date between 1570 and 1640. It examines Hoskins'original thesis and subsequent revisions by R. Machin and C. Currie from both an empirical and an historiographical point of view. It is argued that the rise and fall of the 'Great Rebuilding'thesis was partly due to wider intellectual currents in the study of early modern history and vernacular architectural studies. In conclusion, an alternative approach is sketched to rethinking the Great Rebuilding in cultural rather than economic terms.     

REIMAGINING REPRESSION: NEW CENSORSHIP THEORY AND AFTER

Emerging from the work of Foucault and Bourdieu in particular, a powerful theoretical critique of prevailing notions of censorship and its opposite, free speech, emerged in the waning decades of the last century. The principal theoretical contribution, I will argue, of this “New Censorship Theory” has been not to overthrow the dominant liberal conception of censorship, but rather to bracket this conception as a separate and ultimately subordinate species of censorship. In this article I reexamine the development of New Censorship Theory, especially its antecedents in the Marxist critique of bourgeois civil society. In place of an exclusive focus upon state actions, newer conceptions of censorship have enshrined self‐censorship as the paradigm and have seen traditional forms of censorship as secondary to impersonal, structural forms like the market. I argue that historians' qualms about New Censorship Theory stem from concerns over this erasure of the specificity of state repressive force. Rather than simply accepting the division of censorship into a dichotomy of repressive/authoritative and productive/structural, this article argues that no strict distinction ought to be drawn. Instead, investigations of censorship in the traditional sense must incorporate the insights of newer theories to understand state censors as actors internal to communication networks, and not as external, accidental features. By investigating the intellectual trajectory of New Censorship Theory, I posit a way forward for historians to incorporate its insights while addressing their concerns.     

SYNTHESIS AND ACID RESISTANCE OF MAYA BLUE PIGMENT*

Maya blue is an organo‐clay artificial pigment composed of indigo and palygorskite. It was invented and frequently used in Mesoamerica in ancient times (eighth to 16th centuries). We analyse in this paper one of the characteristics of Maya blue that has attracted the attention of scientists since its rediscovery in 1931: its high stability against chemical aggression (acids, alkalis, solvents, etc.) and biodegradation, which has permitted the survival of many works of art for centuries in hostile environments, such as the tropical forest. We have reproduced the different methods proposed to produce a synthetic pigment with the characteristics of the ancient Maya blue. The stability of the pigments produced using either palygorskite or sepiolite has been analysed by performing acid attacks of different intensities. The results are analysed in terms of pigment decolouration and destruction of the clay lattice, revealed by X‐ray diffraction. Palygorskite pigments are much more resistant than sepiolite pigments. It is shown that indigo does not protect the clay lattice against acid aggression. We show that Maya blue is an extremely resistant pigment, but it can be destroyed using very intense acid treatment under reflux.
