Namilamadeta snideri new genus and species, from the medial Miocene Namba Formation, was found on the western side of Lake Tarkarooloo, South Australia. It is tentatively assigned to the Wynyardiidae and may be the plesiomorphous sister group of the Vombatidae.  相似文献

Following earlier examples of mapping the subsurface of shell bearing sites using augering, we employ percussion coring to identify early Holocene shell midden components at two types of sites on the Northwest Coast of North America. We describe a method for mapping subsurface components at shell bearing sites including basal deposits, paleosols and transitions between distinct cultural components. Our research was undertaken for the purpose of identifying early Holocene shell middens above the modern shore, and as components below large shell midden villages. Our results augment the developmental trajectory of shell middens on the Northwest Coast by suggesting that pre-5000 BP forms of these sites may be more common than previously thought. In light of these results, we argue that the Northwest Coast cultural historical sequence, which locates an increase in the number and rate of accumulation of shell middens beginning 5000 years ago, to be premature. However, there are insufficient data from shell middens in the early Holocene, a sampling problem that the percussion coring methods described here can address.  相似文献

This study investigates the relationship between arts-themed development and the strategies used by neighborhood stakeholders, including artists and other marginalized populations, to maintain their place in gentrifying arts and cultural districts. Using a case study of a state-sanctioned Arts & Entertainment District in Baltimore, MD (U.S.A.), I find that the organizations that are ‘thoughtful’ in their development actively seek to maintain the production of arts and the residency of artists in the neighborhood into perpetuity. At the same time, the influx of arts-themed development helps raise property values and spurs re-colonization of the neighborhood’s large industrial buildings, making it difficult for artists to find legal, affordable live/work spaces in the district. As illegal DIY artists’ spaces are increasingly scrutinized by city inspectors, artists and other marginalized populations lose territory in the district and feel that they are being used for capital interests. This paper evaluates arts-themed development and public–private partnerships as a strategy for maintaining artists in revitalizing neighborhoods and considers the possibilities for a more inclusive arts district through political and community engagement.  相似文献

The “Adam Smith Problem” is the name given to an argument that arose among German scholars during the second half of the nineteenth century concerning the compatibility of the conceptions of human nature advanced in, respectively, Adam Smith's Theory of Moral Sentiments (1759) and his Wealth of Nations (1776). During the twentieth century these arguments were forgotten but the problem lived on, the consensus now being that there is no such incompatibility, and therefore no problem. Rather than rehearse the arguments for and against compatibility and incompatibility, this paper returns to the German writers of the 1850s–1890s and demonstrates that their engagement in this argument represents the foundation of modern Smith scholarship. It is shown that the “problem” was not simply a mistake best forgotten, but the first sustained scholarly effort to understand the importance of Smith's work, an effort that lacked any parallel in English commentary of the time. By the 1890s British writers, overwhelmingly ignorant of German commentary, assumed that there was little more to be said about Smith's work. Belated international familiarity with this German “Problem” played a major role in transforming Smith from a simple partisan of free trade into a theorist of commercial society and human action.  相似文献

Benson, R.B.J., Fitzgerald, E.M.G., Rich, T.H. & Vickers-Rich, P., 2013. Large freshwater plesiosaurian from the Cretaceous (Aptian) of Australia. Alcheringa 37, 1–6. ISSN 0311-5518

We report a large plesiosaurian tooth from the freshwater early–middle Aptian (Early Cretaceous) Eumeralla Formation of Victoria, Australia. This, combined with records of smaller plesiosaurian teeth with an alternative morphology, provides evidence for a multitaxic freshwater plesiosaurian assemblage. Dental and body size differences suggest ecological partitioning of sympatric freshwater plesiosaurians analogous to that in modern freshwater odontocete cetaceans. The evolutionarily plastic body plan of Plesiosauria may have facilitated niche differentiation and helped them to exclude ichthyosaurs from freshwater environments during the Mesozoic. However, confirmation of this hypothesis requires the discovery of more complete remains.

The youngest members of the Ektopodontidae, an enigmatic family of Phalangeroidea, are reported from southwestern Victoria. Four isolated teeth are described as Ektopodon paucicristata sp. nov. (from the ?mid-?late Pliocene, and early Pliocene) and two isolated Pleistocene teeth are assigned to Darcius duggani Rich, 1986. Previously, the youngest known ektopodontid was early Pliocene.  相似文献

Taking an historical approach to the "corporatization of the university," this paper argues that the classroom as a site of political praxis has been neglected in mainstream geography and is a crucial place where such "corporatization" can be challenged. Geographers have expended much energy working out new methods of research and analysis, but have not adequately addressed the link between knowledge production and pedagogy. This paper attempts to bring questions of radical pedagogic practices into mainstream discussions in geography by showing how knowledge came to be viewed primarily in instrumentalist terms during the nineteenth century, and by showing how recent challenges to positivism can open the door to more sophisticated discussions of the topic. The paper argues that by so doing, we will be better equipped to defend our classrooms and more able to promote teaching that matters to radicalgeographers—social justice, critical citizenship, and participatory democracy.  相似文献

运用Ap和Crompton(1998)提出的旅游影响量表,本文从经济、社会文化、拥挤程度、环境、服务和社区态度等方面实证检验了山东省的目的地居民对旅游影响的感知程度、对旅游影响的态度以及对旅游影响的综合评价,探讨了目的地居民对旅游影响的感知与他们对旅游影响的态度之间的关系。研究结果表明,多数情况下目的地居民对旅游影响的感知与态度之间并不相关。  相似文献
