Reappraisal of Austrosaurus mckillopi Longman, 1933 Longman, H.A., 1933. A new dinosaur from the Queensland Cretaceous. Memoirs of the Queensland Museum 10, 131–144. [Google Scholar] from the Allaru Mudstone of Queensland, Australia’s first named Cretaceous sauropod dinosaur. Alcheringa 41, 543–580. ISSN 0311-5518

Austrosaurus mckillopi was the first Cretaceous sauropod reported from Australia, and the first Cretaceous dinosaur reported from Queensland (northeast Australia). This sauropod taxon was established on the basis of several fragmentary presacral vertebrae (QM F2316) derived from the uppermost Lower Cretaceous (upper Albian) Allaru Mudstone, at a locality situated 77 km west-northwest of Richmond, Queensland. Prior to its rediscovery in 2014, the type site was considered lost after failed attempts to relocate it in the 1970s. Excavations at the site in 2014 and 2015 led to the recovery of several partial dorsal ribs and fragments of presacral vertebrae, all of which clearly pertained to a single sauropod dinosaur. The discovery of new material of the type individual of Austrosaurus mckillopi, in tandem with a reassessment of the material collected in the 1930s, has facilitated the rearticulation of the specimen. The resultant vertebral series comprises six presacral vertebrae—the posteriormost cervical and five anteriormost dorsals—in association with five left dorsal ribs and one right one. The fragmentary nature of the type specimen has historically hindered assessments of the phylogenetic affinities of Austrosaurus, as has the fact that these evaluations were often based on a subset of the type material. The reappraisal of the type series of Austrosaurus presented herein, on the basis of both external morphology and internal morphology visualized through CT data, validates it as a diagnostic titanosauriform taxon, tentatively placed in Somphospondyli, and characterized by the possession of an accessory lateral pneumatic foramen on dorsal vertebra I (a feature that appears to be autapomorphic) and by the presence of a robust ventral mid-line ridge on the centra of dorsal vertebrae I and II. The interpretation of the anteriormost preserved vertebra in Austrosaurus as a posterior cervical has also prompted the re-evaluation of an isolated, partial, posterior cervical vertebra (QM F6142, the ‘Hughenden sauropod’) from the upper Albian Toolebuc Formation (which underlies the Allaru Mudstone). Although this vertebra preserves an apparent unique character of its own (a spinopostzygapophyseal lamina fossa), it is not able to be referred unequivocally to Austrosaurus and is retained as Titanosauriformes indet. Austrosaurus mckillopi is one of the oldest known sauropods from the Australian Cretaceous based on skeletal remains and potentially provides phylogenetic and/or palaeobiogeographic context for later taxa such as Wintonotitan wattsi, Diamantinasaurus matildae and Savannasaurus elliottorum.

The historical origins of the vegetative state: Received wisdom and the utility of the text

The persistent vegetative state (PVS) is one of the most iconic and misunderstood phrases in clinical neuroscience. Coined as a diagnostic category by Scottish neurosurgeon Bryan Jennett and American neurologist Fred Plum in 1972, the phrase “vegetative” first appeared in Aristotle’s treatise On the Soul (circa mid-fourth century BCE). Aristotle influenced neuroscientists of the nineteenth and early-twentieth centuries, Xavier Bichat and Walter Timme, and informed their conceptions of the vegetative nervous system. Plum credits Bichat and Timme in his use of the phrase, thus putting the ancient and modern in dialogue. In addition to exploring Aristotle’s definition of the “vegetative” in the original Greek, we put Aristotle in conversation with his contemporaries—Plato and the Hippocratics—to better apprehend theories of mind and consciousness in antiquity. Utilizing the discipline of reception studies in classics scholarship, we demonstrate the importance of etymology and historical origin when considering modern medical nosology.     

Hegel,Analytic Philosophy’s Pharmakon

In this article I argue that Hegel has become analytic philosophy’s “pharmakon”—both its “poison” and its “cure.” Traditionally, Hegel’s philosophy has been attacked by Anglo-American analytical philosophers for its alleged charlatanism and irrelevance. Yet starting from the 1970s there has been a revival of interest in Hegel’s philosophical work, which, I suggest, may be explained by three developments: (1) the revival of interest in Aristotelianism following Saul Kripke’s and Hilary Putnam’s work on natural kinds, and Elizabeth Anscombe’s, Philippa Foot’s, and Putnam’s opposition to the fact-value distinction; (2) the rehabilitation of Hegel’s theories by various philosophers, including Robert Pippin, Terry Pinkard, Fred Beiser, Robert Stern, and Stephen Houlgate; and (3) the Sellars-inspired philosophy of mind of John McDowell and of Robert Brandom. The first and third of these reasons, I argue, have led several analytic theorists to cast Hegel in a more positive light as the “cure” for analytic philosophy. The combined outcome of these changes, both ironic and fitting, is that the Hegelian principle of internal critique has played a significant role not only in analytic philosophy’s rapprochement with Hegel’s philosophy but also in overcoming the Analytic-Continental philosophical divide.     

The Twenty-First Century Federalist

It is unlikely a “third party” will arise to threaten the two-party duopoly that has governed American politics since 1828. It is, however, possible that a new political movement will arise within the Republican Party, stake out new ideological terrain, and make a bid for control of the party apparatus. Movements arise when parties fail to address public challenges, policy entrepreneurs recognize the opportunity, and resources are available to make a bid feasible. Today the two parties have failed to address the increasing fragmentation of American public life. They have, in fact, contributed to fragmentation by appealing to identity politics and by attempting to use the national government as a tool of legal and judicial force against their opponents. A new political movement centered on federalism—the restoration of state and local government and a balance of power between the states and the national government—offers the hope of allowing cultural pluralism to flourish within an overarching political unity. It remains for enterprising candidates to recognize the opportunity and donors to fund them.     

Exploring trade globalization in the long run: The RICardo project

Initiated in 2004, the RICardo project focuses on bilateral trade data of all the world's countries from the early nineteenth century to the eve of the Second World War. The project includes the construction of a database and the creation of a website. It is a pioneering work in the field of historical trade statistics that aims at providing easy-to-access research material to the scientific community and at attracting a wider public to the history of trade relationships. The article emphasizes the originality of the project and sums up its various aspects by reviewing previous trade databases, clarifying the main features of historical trade statistics, and describing the construction and use of the RICardo website.     

The press and issue framing in the Australian mining tax debate

Using supervised learning techniques to code newspaper articles on the Minerals Resource Rent Tax (originally known as the Resources Super Profits Tax), this article analyses sources of partiality and emphasis in media coverage of the issue. It shows that opponents were more successful in airing their views in the opening stages of the debate, but the government's re-branding led to more favourable media coverage. There was a regional bias, however, with newspapers in states dominated by mining interests more critical than newspapers from other states. The only truly national newspaper (the Australian) was notable for having fewer ‘neutral’ articles, with a relatively high number of both negative and positive articles. The Australian Financial Review, meanwhile, had a greater number of neutral articles. Framing remained homogenous over time though variable across publications.

本文使用指导学习技术,对有关矿产资源租借税的报刊文章进行编码,分析了媒体就此话题的报道其中中立性和重点性的根源。研究显示,反对者在辩论的开始阶段成功地传播他们的观点。不过,政府的再推广也达到了有利的媒体宣传效果。当然,会有地区偏差,矿业利益集团控制的州,那里的报纸会比其他州更持批判立场。唯一名副其实的全国性大报登载的“中性”文章明显要少,负面和正面的文章都比较多,而《澳大利亚财经评论》倒是刊登了较多的中性文章。总之,格局一直比较单一,但具体到出版物则有参差。
