Upper Ordovician Phacopida (Trilobita) from Tasmania

Eastonian trilobite faunas of the Gordon Group in Tasmania include the new species Ceraurinella oepiki, Erratencrinurus trippi, and Pliomerina trisulcata, as well as a reedocalymeninid probably allied to Sarrabesia Hammann & Leone, 1997. Ceraurinella and Erratencrinurus have not previously been reported from Australia, the former being predominantly Laurentian but also known from NE China, the Himalaya, and Vietnam, and the latter mostly Baltic/Laurentian. Peri-Gondwanan species of Ceraurinella appear to form a clade, within which Tasmanian and Indian (central Himalayan) taxa are closest relatives.     

Palaeopathology of a crocodile femur from the Pliocene of eastern Australia

A large fossilized crocodilian left femur recovered from the Pliocene Chinchilla Local Fauna of southeastern Queensland, Australia, exhibits a region of proliferative bone, consistent with an episode of osteitis. The nature and location of the pathology suggest a simple fracture with puncture wounds, possibly the result of a crushing bite of another crocodile, followed by infection. The size and morphology of the femur most closely resembles the now extinct Plio-Pleistocene crocodile Pallimnarchus.     

A NOTE ON BILATERAL MONOPOLY AND THE OPTIMUM LOCATION OF VERTICALLY RELATED FIRMS*

This note considers Blair, Kaserman, and Romano's conclusion (1989) that the only optimal solution in the case of bilateral monopoly is the joint profit maximization solution and examines the pattern of industrial location under joint profit maximization.     

给我一个潘多拉星球

当电影《阿凡达》中,潘多拉星球那生气勃勃的森林火光冲天时,易兰听见影院里有人啜泣。于是她想起了巴布亚新几内亚一位妇女眼里的泪光。那几乎被毁掉的原生态生活,不仅发生在电影里,也不停在我们生存的地球上演。     

Efficient but destructive: a test of the dental wash technique using secondary electron microscopy

The Boyadjian et al dental wash technique provides, in certain contexts, the only chance to analyze and quantify the use of plants by past populations and is therefore an important milestone for the reconstruction of paleodiet. With this paper we present recent investigations and results upon the influence of this method on teeth. A series of six teeth from a three thousand years old Brazilian shellmound (Jabuticabeira II) was examined before and after dental wash. The main focus was documenting the alteration of the surfaces and microstructures. The status of all teeth were documented using macrophotography, optical light microscopy, and atmospheric Secondary Electron Microscopy (aSEM) prior and after applying the dental wash technique. The comparison of pictures taken before and after dental wash showed the different degrees of variation and damage done to the teeth but, also, provided additional information about microstructures, which have not been visible before. Consequently we suggest that dental wash should only be carried out, if absolutely necessary, after dental pathology, dental morphology and microwear studies have been accomplished.     

Understanding local innovation systems in peripheral tourism destinations

Tourism destinations in peripheral areas are often large regions established by centralised government agencies to encourage collaboration between dispersed communities and foster innovation. Relatively little research attention has been paid to the impact that centrally defined destination boundaries have on whether and how small communities contribute to innovation at a regional level. This paper examines the case of Burra, a small town in rural South Australia. It analyses the networking, collaboration and knowledge exchange behaviour of tourism stakeholders in the context of the state-government-defined ‘Clare Valley’ tourism region. Data were drawn from a web-based social network analysis, in-depth interviews, historic document analysis and field observations. The study found that the local tourism system had limited aspirations and capabilities to collaborate with other towns in the region. Lack of regional engagement was only partially due to intra-regional competition and resistance to regional boundaries. More significant barriers included a local culture of operating in isolation, an embedded reliance on public sector leadership to manage systemic interactions, an aging system with limited ambition to change and an inability to harness in-migrants and externally based stakeholders to stimulate knowledge transfer. Changing the imposed destination boundaries would have limited impact on the operation of the local system. The paper concludes that effective regional destination development in peripheral areas needs to be better informed by more detailed understandings of local tourism systems and their capacities to engage.
