Traditional and computed tomographic (CT) techniques link modern and Cenozoic fruits of Pleiogynium (Anacardiaceae) from Australia

Computed tomography (CT) and traditional techniques were used to study the internal morphology of modern fruits of Pleiogynium timoriense (DC.) Leenh., and phosphatized and silicified fruits that were considered to belong to the genus. The results demonstrate that phosphatized fruits from the Oligocene–Miocene Dunsinane site at Riversleigh and silicified fruits from the Oligocene Glencoe Site, which are both in Queensland, are referable to Pleiogynium. The Riversleigh material (Pleiogynium wannanii Rozefelds, Dettmann & Clifford sp. nov.) is very similar to extant P. timoriense (DC.) Leenh. Both possess locules that, in the vertical axial plane, are asymmetrically reniform and enclosed by a two-layered endocarp, the inner layer woody and resistant to decay, the outer of fibres and parenchyma, surrounded by a mesocarp of fibres and sclereids and a parenchymatous exocarp. The outer mesocarp is sculpted by meridionally arranged, elongate depressions (germination apertures) situated at the dorsal surface of each locule; erosion of the mesocarp and outer endocarp provides passage for emergence of the embryo’s radicle on germination. The silicified material from Glencoe (P. parvum Rozefelds, Dettmann & Clifford sp. nov.) is smaller in all its parts and has locules that are ovate in the vertical axial plane. Discrete, cap-like, opercula are not evident in the fruit wall of the fossil and extant fruits studied. The presence of Pleiogynium, and associated taxa, indicates the existence of rainforest communities at Glencoe, and mixed open forest/rainforest at Riversleigh during Oligocene–Miocene times. The multilocular, fossil fruit described as Pleiogynium mitchellii Collinson, Manchester and Wilde from the Eocene deposits at Messel Quarry, Germany, is not considered to belong in the genus, as evidence of elongate depressions on the dorsal surface of the fruit stones has not been demonstrated conclusively, and its internal morphology/anatomy differs significantly from that of Pleiogynium.     

Heroes and Political Communities in John Ford's Westerns: The Role of Wyatt Earp in My Darling Clementine

Abstract

Widespread moral corruption, particularly of the sort fostered by their internal security agencies, was a key feature of communist regimes. The Lives of Others provides a dramatic portrayal of this phenomenon as it occurred in East Germany. The film can appear, given its central story of the moral redemption of a Stasi officer through his becoming intrigued by the lives of artists, to be an overly idealistic or audience-pleasing testament to the humanizing power of art. But the film also reveals the possible moral corruption of the artists. This essay provides a typology of the sorts of moral corruption exemplified by the situations of different characters in the film and shows that the main artist is actually saved from his impending corruption by the Stasi officer's actions. This reciprocal rescue is the key feature of the film's plot; it teaches that while art can undermine and resist totalitarian corruption, it is also susceptible to its snares—especially when it apolitically relies upon its own resources.     

Here We Go Again: Presidential Elections and the National Media

The fear of death is a major preoccupation in the West. This is not surprising given the debt we owe to Hobbes, who encourages this fear and makes it a central feature of his account of human nature. Rousseau, in contrast, wishes to reduce this fear as much as possible. Amour propre and the humanity Rousseau encourages are incompatible with excessive concern for self-preservation. This accounts for his antipathy to doctors and the medical arts. Rousseau, through his presentation of Emile and the savage, initially claims that the fear of death is unnatural and that humans should take a stoic stance toward it and all human attachments that lead to our "feeling death twice." A closer reading reveals that humans always have an awareness of death and that modern humans cannot entirely avoid these attachments. We can, however, avoid making preservation our highest goal, and this is essential to our happiness and ability to have compassion for others.     

The Conservation of English Cultural Built Heritage: A Force for Social Inclusion?

Debates about the socially inclusionary potential of heritage have to date focused principally on heritage sites and museums. Relatively little attention has been paid to the wider Cultural Built Heritage (CBH) that surrounds us in our everyday lives. This paper starts with a brief theoretical exploration of the social role of heritage and the key policy background. Then, based on an understanding of policy and action in England, this paper sets out a framework for considering how this wider CBH might contribute to social inclusion. A fundamental binary divide is made between the role of CBH as historic places and opportunity spaces in which regeneration may occur. However, in neither case is action necessarily socially inclusive. The paper concludes that a greater clarity of objectives and definitions is necessary if CBH is to meet its potential to be socially inclusionary.     

The Heritagescape: Looking at Landscapes of the Past

Heritage sites are one of the most visible, accessible and tangible manifestations of heritage and are also some of the essential building blocks of heritage. Yet we are still without a sense of how they operate over time and in relation to each other. This paper will introduce the notion of the ‘heritagescape’ as a means of interpreting and analysing heritage sites as unique social spaces that offer an experience of the past. In contrast to previous attempts to investigate these places, the heritagescape offers the means to focus both on the underlying similarities and also on the relationships of different sites to each other. As such, heritagescape offers a coherent and overarching methodology by which to identify the universal processes and elements that characterise heritage sites and will allow us to take our examination of heritage as a cultural phenomenon into the future.     

Divided Government and the Rise of Social Regulation

Political scientists have debated the causes of divided government since the Reagan administration. In addition, a handful of scholars have also pondered the possible consequences of divided party rule for politics and policy. Still, one serious oversight in the divided'government literature is the potential consequences of divided party rule for the types of policy pursued during divided and unified party regimes. Divided government may create incentives for conflicting institutions to use social regulation debates, often considered the most divisive public policy debates, as "wedges" in order to damage the opposing party in future elections. Each party also has an incentive to embrace social regulation in order to reaffirm its allegiance to its core constituency. This article tests the hypothesis that divided government produces more important social regulation votes than unified government. I define the population of important votes as all Key Votes in the House of Representatives from 1953 to 1998. The data analysis reveals that important social regulation votes are in fact more prominent during eras of divided government than during unified party control. This finding has potential implications for the tenor of our national politics as well as the public trust.
