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.  相似文献

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.  相似文献

In the early 1990s, Italy was drawn into a spiral of unprecedented transformation precipitated by changes that were taking place both inside Italy and on the international scene. Financial, political and institutional crises were superimposed in ways that brought into question the survival of the whole Italian system. This occurred at a moment when world geo-political relations were shifting dramatically and radically changing established relations, attitudes and policies and marked the beginning of a long period that is often described as a ‘transition’. But since the outcomes still remain far from certain, it is necessary to consider how accurately this term describes what has been taking place in Italy over the last two decades. This paper shows how more careful identification of the different phases and components of the crisis enable us to understand why the upheavals of 1992–94 have led to a systemic crisis of the Italian economy and politics.  相似文献

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.  相似文献

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.  相似文献

Initiated by geoscientists, the growing debate about the Anthropocene, ‘planetary boundaries’ and global ‘tipping points’ is a significant opportunity for geographers to reconfigure two things: one is the internal relationships among their discipline's many and varied perspectives (topical, philosophical, and methodological) on the real; the other the discipline's actual and perceived contributions to important issues in the wider society. Yet, without concerted effort and struggle, the opportunity is likely to be used in a ‘safe’ and rather predictable way by only a sub‐set of human‐environment geographers. The socio‐environmental challenges of a post‐Holocene world invite old narratives about Geography's holistic intellectual contributions to be reprised in the present. These narratives speak well to many geoscientists, social scientists, and decision‐makers outside Geography. However, they risk perpetuating an emaciated conception of reality wherein Earth systems and social systems are seen as knowable and manageable if the ‘right’ ensemble of expertise is achieved. I argue that we need to get out from under the shadow of these long‐standing narratives. Using suggestive examples, I make the case for forms of inquiry across the human‐physical ‘divide’ that eschew ontological monism and that serve to reveal the many legitimate cognitive, moral, and aesthetic framings of Earth present and future. Geography is unusual in that the potential for these forms of inquiry to become normalised is high compared with other subjects. This potential will only be taken advantage of if certain human‐environment geographers unaccustomed to engaging the world of geoscience and environmental policy change their modus operandi.  相似文献

What does it mean for us to be citizens of the Anthropocene, both individually and collectively? This essay tries to answer that question in order to stimulate a wider conversation about how we should respond to and shape the socioecological transformations ahead of us. 1 1 Many of the ideas and arguments in this essay are explored in greater depth in my book (in preparation), Hope and Grief in the Anthropocene: Re‐conceptualising Human‐Nature Relations (Routledge, UK). Questions of grief are also explored in Head, L. 2016 ‘Grief, loss and the cultural politics of climate change’, a chapter in H. Bulkeley, M. Paterson and J. Stripple (eds) Towards a Cultural Politics of Climate Change: Devices, Desires and Dissent.

This article systematically reviews and synthesises academic, peer‐reviewed literature to assess the state of knowledge concerning socio‐economic vulnerability to climate change impacts and environmental hazards in New South Wales and Queensland, Australia. It focuses upon empirical research that identifies socio‐economic factors associated with vulnerable subpopulations. Using systematic review methods, 35 articles met the inclusion criteria. These articles are analysed according to their general characteristics, the methods used, and the factors reported to be associated with socio‐economic vulnerability. This body of evidence reveals that (1) the majority of the knowledge about socio‐economic vulnerability in New South Wales and Queensland has only recently emerged; (2) more knowledge has been published about Queensland; and (3) extreme temperature is the most researched environmental hazard. Despite increased research activity over time, the number of factors repeatedly demonstrated to influence socio‐economic vulnerability is small. Age, gender, place of residence, and pre‐existing illness were the most commonly reported factors, although the influence of these factors upon socio‐economic vulnerability is complex. There is scope to extend the empirical research base across a broader range of climate‐related hazards and to better link findings from the domains of climate change vulnerability and population health.  相似文献

宗祧承继是宗族研究的一个重要内容,学界对明清宗族继承问题研究已久,也取得了丰硕的成果,对于越继和降继,则甚少涉及。先贤们对徽州宗族社会有诸多理想性的描述,然而这些描述在很大程度上只是一种表象,现实的徽州社会要复杂得多,越继和降继就是其表现之一。探讨这两种承继方式,对于更好地解读宗祧承继和剖析明清时期徽州宗族社会的发展脉络,都有一定的积极意义。  相似文献
