Oldest Australian vespertilionid (Microchiroptera) from the early Miocene of Riversleigh,Queensland

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.     

Tracing the origin of Chinese early white porcelain in the late sixth century—evidence from Xing kiln

As the criterion used by archaeologists for determining early white porcelain is quite ambiguous, the origin of Chinese white porcelain remains a point of disagreement. In this study, we systematically investigate 61 typical Xing porcelains of the late Northern dynasties to the early Sui dynasty (550–600 CE) using spectrophotometer, X-ray fluorescence (XRF), scanning electron microscopy (SEM), and X-ray powder diffraction (XRD), and analyze the differences between early white porcelain and celadon of Xing kiln in terms of their whiteness and raw materials characteristic. The results show that early white porcelain is a new type of ware that differs from celadon, which can be distinguished by whiteness, with a whiteness greater than 8% being early white porcelain and a whiteness less than 8% being celadon. It is assumed that the ancient potters created the whiter wares based on celadon by improving the glaze and selecting new raw materials for the body, but the production of this type of ware was short lived and subsequently refined in the Sui dynasty (581–618 CE) owing to the limited improvement in whiteness.     

Jaume Cabré's Viatge d’hivern and the Short Story Cycle

Critics have been uncertain as to the genre of Catalan writer Jaume Cabré's 2000 book, Viatge d’hivern. The confusion, I argue, is due to the fact that the volume is a short story cycle, a literary form situated midway between the novel and the short story collection. Forrest Ingram differentiates among composed, arranged, and completed cycles, and Cabré's comments in his Epilogue to Viatge d’hivern indicate that the book is an example of the third category. While he composed its fourteen narratives over a period of years, when he revised them for inclusion in a single volume he discovered that various threads, some secret and others more obvious, connected the stories. In this essay I examine ways in which theme, structure, and motifs, as well as recurrent imagery and wording, form a web of associations among the individual units of Viatge d’hivern.     

Smoking bans for private vehicles: children's rights and children's voices

Smoking bans have recently expanded to private vehicles in which children are present. This study considers the place of children's rights and children's voices in this policy initiative, with respect to the Canadian context, where vehicular smoking bans have been widely adopted. First, we examine print media reports, finding children's right to health was acknowledged less frequently than an array of competing adult rights. Children's voices were largely absent from the record. Second, we report on focus groups involving 23 young people in Edmonton, Alberta, highlighting participants' strong support for bans, based on their knowledge of health harms, aversion to smoke, and awareness that children have limited ability to contest adult authority in vehicles. We conclude that vehicular smoking bans may address the situation whereby children are forced to share an unhealthy environment, in breach of their rights.     

China’s services sector: the new engine of economic growth

This paper presents a review of services sector development in China. It is found that China’s services have recently emerged as the dominant contributor to economic growth and job creation. Trade in services has also increased dramatically, although China maintains a huge deficit. In comparison with economies at a similar stage of development, however, China’s services sector is lagging behind. Both GDP and employment shares of the services sector are relatively small. Services trade also accounts for a relatively small share of China’s total trade. In particular, China’s new services are underdeveloped. As per capita income rises and resultant urbanization accelerates, the country’s services sector is expected to expand further and hence play a key role in rebalancing China’s economy away from its over-reliance on manufacturing and exporting. To reach this goal, further reforms and prudent government policies are needed.     

‘They have to abide by our laws … and stuff’: ethnonationalism masquerading as civic nationalism

The long established distinction between civic nationalism and ethnonationalism is useful heuristically to understand different dimensions of nationalism and perhaps track a movement from ethnic forms to civic allegiances, though some have challenged its empirical veracity and others question the normative implications of such a distinction. This paper demonstrates the ways in which the two are elided in everyday discourses about migrants in Australia. We argue suspicion of cultural difference, identified more than three decades ago as the new racism, has given way to talk of the need for migrants to ‘follow the law’. This serves rhetorically to reinforce the notion that migrants, often implied to overlap with the category ‘Muslims’, are insisting on breaking the law and/or changing it and are therefore culturally incompatible with a modern liberal democracy. We argue that since ethnic nationalism, like racism, is out of favour normatively, ethnic nationalist arguments are now superficially concealed beneath the acceptable language of civic nationalism. The manner in which this occurs is mapped discursively using data from a corpus of twenty seven focus groups conducted around Australia.     

Surface controls on the characteristics of natural CO2 seeps: implications for engineered CO2 stores

CO₂ injected into rock formations for deep geological storage must not leak to surface, since this would be economically and environmentally unfavourable, and could present a human health hazard. In Italy natural CO₂ degassing to the surface via seeps is widespread, providing an insight into the various styles of subsurface ‘plumbing’ as well as surface expression of CO₂ fluids. Here we investigate surface controls on the distribution of CO₂ seep characteristics (type, flux and temperature) using a large geographical and historical data set. When the locations of documented seeps are compared to a synthetic statistically random data set, we find that the nature of the CO₂ seeps is most strongly governed by the flow properties of the outcropping rocks, and local topography. Where low‐permeability rocks outcrop, numerous dry seeps occur and have a range of fluxes. Aqueous fluid flow will be limited in these low‐permeability rocks, and so relative permeability effects may enable preferential CO₂ flow. CO₂ vents typically occur along faults in rocks that are located above the water table or are low permeability. Diffuse seeps develop where CO₂ (laterally supplied by these faults) emerges from the vadose zone and where CO₂ degassing from groundwater follows a different flow path due to flow differences for water and CO₂ gas. Bubbling water seeps (characterized by water bubbling with CO₂) arise where CO₂ supply enters the phreatic zone or an aquifer. CO₂‐rich springs often emerge where valleys erode into CO₂ aquifers, and these are typically high flux seeps. Seep type is known to influence human health risk at CO₂ seeps in Italy, as well as the topography surrounding the seep which affects the rate of gas dispersion by wind. Identifying the physical controls on potential seep locations and seep type above engineered CO₂ storage operations is therefore crucial to targeted site monitoring strategy and risk assessment. The surface geology and topography above a CO₂ store must therefore be characterized in order to design the most effective monitoring strategy.     

The emergence of agropastoralism: Accelerated ecocultural change on the Andean altiplano, ∼3540–3120 cal BP

In the fourth millennium BP, there were major environmental and cultural changes on the Andean altiplano of South America, but the chronology remains vague. A recent synthesis describes a slow, gradual transition from hunting and gathering to agropastoralism. This proposal is tested by refining the date of the onset of more humid and stable conditions, around 3550 cal BP, based on a Bayesian model of 26 dates from Lake Wiñaymarka and an updated calculation of the lacustrine offset. This is compared to Bayesian models of 191 dates from 20 archaeological sites, which incorporate a number of recently processed radiocarbon dates. A synthesis is presented of 15 full coverage surveys, a summed probability distribution, and a Bayesian model of the transition to ceramics, which together support a scenario of a very rapid demographic increase. Fourteen models from archaeological sites are cross-referenced in a composite model, which identifies a brief, altiplano-wide emergence of agropastoralism with starting and ending boundaries of 3540 and 3120 cal BP, respectively. This starting boundary correlates strongly with the onset of improving environmental conditions, indicating synchronous cultural and environmental change. The suite of accelerating cultural changes included a marked reduction in mobility, a demographic surge, increased subsistence diversity, the adoption of ceramics, farming and the integration of camelid herding into a remarkably resilient economic strategy still in use today. This is a highly relevant but yet to be used comparative case study for the variable tempos of ‘big histories’, and ecocultural interactions that generate rapid, emergent episodes of wide-spread and enduring cultural change.     

New Architectural Models and Building Tradition: A Dialogue in Early Modern Sardinia – The Jesuit Church in Sassari

Architecture in early modern Sardinia is characterized by a strong continuity with previous practices. In the second half of the 16th century, new models join the Gothic building tradition, linked in particular to trends in military engineering and Classicism of the Catholic Counter-Reformation. The Jesuit church in Sassari offers an interesting example of the intertwining of these architectural modes, which originated with a sudden change of leadership at the site. Giovan Maria Bernardoni, an Italian Jesuit architect, initially modeled the church after the Gesù in Rome, and it was partially built under his direction. After his departure from Sardinia, local master builders finished the construction, following the Gothic tradition and possibly some external influences. This article analyzes the church, particularly focusing on the challenges presented by its articulated vaulting system completed between 1587 and 1609.
