South polar greenhouse insects (Arthropoda: Insecta: Coleoptera) from the mid-Cretaceous Tupuangi Formation,Chatham Islands,eastern Zealandia

Stilwell, J.D., Vitacca, J. & Mays, C., April 2016. South polar greenhouse insects (Arthropoda: Insecta: Coleoptera) from the mid-Cretaceous Tupuangi Formation, Chatham Islands, eastern Zealandia. Alcheringa 40, xxx–xxx. ISSN 0311-5518

Rare insect body fossils have been discovered for the first time after 175 years of research on the Chatham Islands, eastern ‘Zealandia’. The coleopteran (beetle) insects, dated to ca 95 Ma and extracted from fine-grained, upper delta plain facies in the lower Upper Cretaceous (Cenomanian–lowermost Turonian) Tupuangi Formation at Waihere Bay on the remote Pitt Island, represent the most southern, polar-latitude (ca 70–80°S) faunal assemblage from the Cretaceous recorded to date. Three species are represented in the insect fauna: a portion of a segmented abdomen of a probable carabid? ground beetle and two distinct coleopteran elytra, one preserved with a brilliantly iridescent carapace upon discovery, comparable with Cretaceous taxa within the Buprestidae (metallic wood borers), but identification with the Chrysomelidae (leaf beetles) or Tenebrionidae (darkling beetles) can not be discounted entirely. Another specimen has more weakly preserved greenish iridescence and has a morphology consistent with Carabidae; given the preservational deficiencies and rarity of material, the specimens are attributed to Buprestidae? genus et species indeterminate and Carabidae? genus et species indeterminate A and B, respectively. These coleopteran fossils represent the only recorded iridescence in Mesozoic invertebrates from Zealandia. Importantly, these mid-Cretaceous insects existed in South Polar forests near the height of the ‘hothouse’ phase of relatively warm, alternating intervals of full daylight in the summer months and total darkness during the winter, before eastern Zealandia diverged at ca 83 Ma from the Marie Byrd Land region of West Antarctica, as part of the final break-up of Gondwana.

Embracing the Complexities of ‘Big Data’ in Archaeology: the Case of the English Landscape and Identities Project

This paper considers recent attempts within archaeology to create, integrate and interpret digital data on an unprecedented scale—a movement that resonates with the much wider so-called big data phenomenon. Using the example of our work with a particularly large and complex dataset collated for the purpose of the English Landscape and Identities project (EngLaID), Oxford, UK, and drawing on insights from social scientists’ studies of information infrastructures much more broadly, we make the following key points. Firstly, alongside scrutinising and homogenising digital records for research purposes, it is vital that we continue to appreciate the broader interpretative value of ‘characterful’ archaeological data (those that have histories and flaws of various kinds). Secondly, given the intricate and pliable nature of archaeological data and the substantial challenges faced by researchers seeking to create a cyber-infrastructure for archaeology, it is essential that we develop interim measures that allow us to explore the parameters and potentials of working with archaeological evidence on an unprecedented scale. We also consider some of the practical and ethical consequences of working in this vein.     

Making the Dead Visible: Problems and Solutions for “Big” Picture Approaches to the Past,and Dealing with Large “Mortuary” Datasets

There can be few “bigger” questions than the nature and development of human experience and self-awareness and few better ways to study it than through the changing treatment of the dead over time. Funded by the John Templeton Foundation, the ‘Invisible Dead’ project (Durham University) is exploring diachronic changes in mortuary practices across two regions: Britain and the Levant. In doing so, it uses archaeology as a way to approach fundamental questions about the human condition. This paper explores the principal difficulties faced during the construction of a database for this project and their wider relevance for the development of robust and successful methods for the study of large “mortuary” datasets in the future. It discusses the issues and biases identified within the mortuary record and how the project has sought to mitigate some of these. By adopting a flexible and ultimately expandable approach to data entry and analysis, value can be added to legacy datasets and “grey” literature, allowing us to make comparisons between regions which are both geographically and chronologically distinct.     

Implications of climate change for glacier tourism

For more than 100 years, the Fox and Franz Josef Glaciers in Westland Tai Poutini National Park have attracted thousands of tourists annually and have emerged as iconic destinations in New Zealand. However, in recent years, the recession of both glaciers has been increasingly rapid and the impacts on, and implications for, visitor experiences in these settings remain relatively unexplored. A mixed-method approach was adopted to investigate visitor experiences and stakeholder perspectives through an assessment of climate-related changes on tourism at the glaciers in Westland Tai Poutini National Park. The bio-physical conditions at both the Franz Josef and Fox Glaciers were reviewed in order to assess the magnitude and rate of retreat. Perceptions of climate change risk and awareness of impacts in the National Park were assessed through stakeholder interviews (n = 13) and a visitor survey (n = 500) was used to better understand how impacts at these sites have affected and may continue to affect visitor experiences. Research results were reported to local communities via a series of public talks. Results revealed the fundamental importance of viewing the glaciers as a significant travel motive of visitors, suggesting that there is a ‘last chance’ dimension to their experience. Furthermore, the results demonstrate a high adaptive capacity of local tourism operators under rapidly changing environmental conditions. The implications of altered visitor experiences for tourism operators and protected area managers are discussed in light of these findings.     

Austerity and consociational government in Northern Ireland

Abstract

This article examines the institutional crisis of the Northern Ireland Assembly in 2015 as a case study on the impact of austerity on multiculturalism in Ireland. I make a case for viewing the Assembly as a multicultural institution through pointing to the historical role of community relations policy, which was directed at reconciling “sectarian” Irish nationalists and Ulster unionists. It did so through shifting from an understanding of the conflict as one based on the struggle for Irish national self-determination to one based on conflicting identities. I argue that Sinn Féin’s embracing of multiculturalism is a product of its accommodation to British rule in Ireland. Sinn Féin has made a virtue out of its political volte-face by becoming the strongest advocate of ethnic Irish nationalism in Northern Ireland. The ethnic power politics of Sinn Féin has found its unionist equivalent in the political manoeuvrings of the Democratic Unionist Party. Austerity measures imposed by the Westminster government have created problems for the parties in the power-sharing Assembly, problems that threaten the collapse of the Assembly. It is because of, rather than in spite of, the multicultural mechanisms embedded in the Assembly that the institution has got to crisis point. This is an institutional crisis, not a crisis of multiculturalism.     

Topping Off and Bottoming Out: Setting Budget Priorities Through Executive Power

This article examines the role of the institutional power of executives in public budgeting; specifically, how executives change spending on particular budget items. Leveraging extant theories of the policy process concerning preference expression, attention, and institutions, we argue that executives deepen large cuts and boost large increases in budgetary change. The strictures of the budgetary process force trade-offs for executives in preference expression such that increases to preferred categories typically require decreases in other categories. Literatures in public policy and political representation suggest that all executives would like to express fiscal preferences, thereby contributing to categorical budget oscillations; however, not all executives are created equal. We employ quantile regression to examine whether the institutional strength of governors determine cuts, stasis, and expansion in spending across all budget functions in the American states between 1985 and 2009. Our model includes a host of political and economic variables found in the literature of fiscal policymaking, such as partisanship and divided government. The desire to change policy may be widely shared across executives, but we find that the ability to “top off” categorical increases and bottom out categorical decreases is a function of an executive's capacity to call attention to preferred categories via agenda-setting power and to secure those changes via veto power. The findings show strong governors are well positioned to influence public policy through the budgetary process.
