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

Residential field courses are important and should be designed and delivered to maximize their value to students, staff and institutions. In this context, we use a novel approach involving analysis of the daily affective and conative reflections of students immersed in the field course experience to better understand student engagement with fieldwork. We show that students base their field course choice on a range of factors (costs and benefits) and that these choices subsequently influence student expectations and motivation to engage with fieldwork. We also show that the motivation of students to engage with fieldwork-based learning varies from person to person and from day to day. Our findings suggest that having a more nuanced understanding of the decisions students make when deciding which field course to enrol upon would enhance our ability to design attractive, accessible and useful field courses; that having an awareness of the expectations of students around field courses would enable us to better prepare them to undertake them; and that students are more motivated when they are afforded an opportunity to work independently and perceive themselves to have ownership of their learning.  相似文献

On gaining independence in 2002 after a protracted struggle against Indonesian occupation, the sovereign Timor‐Leste state began to assert its sovereignty in a range of discursive and expressive media. These assertions developed a distinct ‘language of stateness’ that is the focus of this article. This East Timorese expression of state sovereignty draws heavily on the legacy of the Timorese resistance struggle and on a variety of other sources of symbolic power such as flags, buildings, logos, and uniforms. Yet these efforts have been contested by a range of non‐state actors in Timor‐Leste and the shape that this language of stateness has taken now evokes complaints from martial arts groups (MAGs), ritual arts groups (RAGs), and veterans' organisations that seek to ‘become like the state’ themselves, and who also employ a ‘national language of stateness’ in the form of flags, graffiti, and official buildings. While not challenging the idea of an independent East Timorese state per se, these groups question the prerogative of the state to use and define the language of stateness. In this article I explore the way the state and its challengers use ‘languages of stateness’ and how this shapes their ambivalent stance vis‐à‐vis each other, with both sides often drawing upon a discourse of the fulfilment of the millenarian promises that have for a long time been tied to the achievement of independence.  相似文献

Endogenous growth models are built around the concept of a knowledge stock. This knowledge stock can also be interpreted as a localized stock that operates at the regional level, as is common in the regional innovation systems literature. We use data from the second, third and fourth Community Innovation Surveys (covering 1994–1996, 1998–2000 and 2002–2004) to measure the build-up of knowledge at a very low regional aggregation level (“across streets and hallways”) in the Netherlands. In doing so, we account for regional agglomeration effects. We find that such local knowledge stocks have a small influence on innovation and are far outweighed by firm-specific characteristics.  相似文献
