An upper molar of a small bat, here described from an early Miocene freshwater lime-stone deposit at Riversleigh, northwestern Queensland, is the oldest record in Australia of the microchiropteran family Vespertilionidae. The new taxon is referred to the cosmopolitan genus Leuconoe, but it does not appear to be closely related to the two extant Australian species of this genus. 相似文献
During the post-war period, margarine was re-conceptualised as a value-added product with distinct health benefits. This article contextualises the advertising of margarine as a healthy food, focusing on Unilever’s Flora brand as an important case study in legitimising the emergent role of disease prevention as a marketing tool. It uses the methodology of visual culture to examine how advertising employed chronic disease prevention as a selling tool. This article assesses how the post-war environment gave rise to new ways of visually advertising food, and how these promoted innovative visualisations of food, the body and their interactions with health. 相似文献
Binfield, P., Archer, M., Hand, S.J., Black, K.H., Myers, T.J., Gillespie, A.K. & Arena, D.A., June 2016. A new Miocene carnivorous marsupial, Barinya kutjamarpensis (Dasyuromorphia), from central Australia. Alcheringa 41, xx–xx. ISSN 0311-5518.
A new dasyuromorphian, Barinya kutjamarpensis sp. nov., is described on the basis of a partial dentary recovered from the Miocene Wipajiri Formation of northern South Australia. Although about the same size as the only other species of this genus, B. wangala from the Miocene faunal assemblages of the Riversleigh World Heritage Area, northwestern Queensland, it has significant differences in morphology including a very reduced talonid on M4 and proportionately wider molars. Based on the structural differences and the more extensive wear on its teeth, the central Australian species might have consumed harder or more abrasive prey in a more silt-rich environment than its congener, which hunted in the wet early to middle Miocene forests of Riversleigh.
How do policymakers respond to crises? The Narrative Policy Framework (NPF) answers this question by focusing on the contest over policy narratives. This paper focuses on the individuals constructing those policy narratives, conceptualizing them as policy narrators. Using a case study approach, we analyze seven counties located in a major oil and gas formation in Texas, which in early 2020 faced both an oil bust and the onset of COVID-19. We explore four sets of propositions about how policy narrators source, synthesize, and share their policy narratives. We find that while their narratives vary, the structure of those narratives is similar; their backgrounds shape how they source narratives, and they tailor their levels of narrative breach to the action (or inaction) they hope for. They avoid casting other local actors as villains, place their audience as the hero, and situate themselves as either supporting or a member of that audience, stressing their common ties. From these findings, we put forward a working definition of policy narrators, identify how they fit into the NPF, and discuss how they relate to other types of policy actors, including policy entrepreneurs. 相似文献
