Outsider and insider views of Saigon/Ho Chi Minh City: The Lover/L'Amant, Cyclo/Xích lô, Collective Flat/Chung c and Bargirls/Gái nh y

This article addresses representations of Saigon/Ho Chi Minh City in four films made since đ     i m     i , the opening up of Vietnam to western influences, initiated in 1986. The Lover/L'Amant (1992) is a Franco-British heritage film which reconstructs the city from a Eurocentric neocolonial perspective, while Cyclo/Xích lô (1995), a French-funded film made by a France-based Vietnamese filmmaker, is a contemporary poetic thriller which treats the city expressively as the site of present-day corruption and violence. The nostalgia evident in these two 'outsider' films is contrasted with the more complex views of the city in two state-funded low-budget 'insider' films by local Vietnamese filmmakers, Collective Flat/Chung c     (1999) and Bargirls/Gái nh     y (2003); the first, an intellectual fable set in the decade or so following reunification/Independence in 1975 which recalls an attempt at collective living, the second, a hugely popular treatment of contemporary urban realities, both corrupt and progressive. Examining how the mise-en-scène and narratives of the city differ from film to film, the essay takes the representation of the city through changing historical, political, social and economic times, from colonial-orientalist Saigon to corrupt, capitalist Ho Chi Minh City via the slow degeneration of the postwar socialist/collectivist experiment. In so doing, it confirms the importance of the films' moments and contexts of production in the construction of Saigon/Ho Chi Minh City as a cinematic 'city-text'.     

Cardboard monuments: City, language and 'nation' in contemporary Telugu cinema

This paper looks at how the city of Hyderabad, the capital of the south Indian state of Andhra Pradesh and production centre of the Telugu film industry, has been represented in recent popular cinema. It outlines the history of a new mode of representing the city in Telugu cinema and argues that its significance lies in the tendency to delocalize the city. Criminalization of the city's older inhabitants, who are marked by either religion (Islam) or their 'non-standard' dialect of Telugu, often accompanies this move. In the process, any claims that they might have on the city are delegitimized. Okkadu, a major commercial hit, restaged the country versus city dichotomy and the antagonisms complicated by cultural and political tensions between the three constituent regions of Andhra Pradesh. This film follows the late 1990s trend in the film industry to recreate entire cityscapes within the studio, ensuring that location shooting in busy city streets and neighbourhoods merely returns us to the grandeur of lavish and 'realistic' studio sets. It reconstructs Hyderabad's most recognizable monument, the 400-year-old Charminar, in addition to its obviously imaginary residential neighbourhood. This paper looks at how and why the city of Hyderabad, especially its older parts, for which Charminar is a metonym, is rendered into a fantasy space in the film.     

云南高原保山市城市气候分析

利用保山市及其郊区昌宁1964-2010年47 a的气象观测资料,主要选取城区与郊区同期的气温、相对湿度数据进行对比分析,发现保山市城市热岛、于岛强度均逐年增强.热岛强度季节变化春季最强,秋季最弱;日变化T02:00达到最强,而T 14:00最弱.干岛季节变化冬季最强,夏季最弱;日变化T02:00最强,而白天较弱.同时,利用灰色模型对保山市城市热岛与干岛强度进行关联度分析,结果表明:对城市热岛、干岛强度影响较大的人文因子均是年末人口,而影响最大的自然因子分别是降水量和总云量.     

南宁市坛洛镇岩溶塌陷群成因机制分析

岩溶塌陷是岩溶区较为常见的地质灾害,对其成因机制的研究有助于针对性的进行综合防治。为了弄清2012年6月在广西南宁市坛洛镇连续发生的岩溶塌陷的成因及发育机制,在塌陷群发生地区开展了现场调查、地球物理勘探、水文地质工程地质钻探、地下水动态长期监测、岩土样测试等多项工作。结果表明,坛洛岩溶塌陷群是各种不良因素共同作用的产物。其致塌因素主要包括特殊的“水-土-岩”组合及人为活动。研究区地下水位埋深较浅,土体结构以粘性土为主,渗透系数较低且易崩解,地下岩溶极为发育。高强度的人工地下水开采活动是坛洛岩溶塌陷的诱因。深入分析其发育机理,认为塌陷群是渗流潜蚀效应、增荷失托效应和水位波动产生的气压差效应等3个力学效应综合作用下发生的,其致塌模式是重力致塌、潜蚀致塌、真空吸蚀致塌和冲爆致塌等4种模式的相互结合。根据岩溶塌陷的发生顺序推断坛洛镇岩溶塌陷群的发育过程可分为缓慢发育—塌陷诱发—塌陷集中爆发3个阶段,各阶段的主要地质营力有所不同。

State rescaling and new metropolitan space in the age of austerity. Evidence from Italy

This article presents the changes that are emerging in the Italian national policies mainly through the discussion of the contents both of the recent metropolitan reform initiative, and the national programming documents for metropolitan cities related to European Programming period 2014–2020. In Italy, which faced severe political difficulty and economic stagnation after 2008 global crisis, the production of the new metropolitan scale became one of the tools for the implementation of austerity measures. The paper examines whether the understanding of the new metropolitan scale in the Italian geography of austerity can be strengthened through a careful engagement with the body of literature on state rescaling and on austerity policies. The paper illustrates how that the apparently neutral emphasis on metropolitan city scale, first can be understood as a crucial tool of an austerity measures; second, it implies a rescaling of public power and, third, it neglects the multifaceted notion of the urban and the trans-scalar territorial governance relationships.     

The Pelona–Orocopia–Rand and related schists of southern California: a review of the best-known archive of shallow subduction on the planet

ABSTRACT

The Pelona–Orocopia–Rand and related schists of southern California are an archetypal example of an exhumed shallow subduction complex. ‘The schist’ comprises mainly trench materials underthust beneath continental arc rocks during Late Cretaceous–early Cenozoic collision of one or more oceanic plateaux with southern California. The arc-on-trench relationship, without intervening mantle or lowermost crust, implies that significant subduction erosion accompanied shallow subduction. Upsection increases in metamorphic grade (~150 ± 100°C/km) and spatial variations in age and peak temperature provide an ~50 million year long record of tectonic underplating within a cooling system. Evidence for palaeoseismic events in earliest formed and hottest (locally transitional granulite grade) schists provides a possible field-based record of episodic tremor and slow slip events such as detected in several modern shallow subduction zones. Structural ascent of the schist was achieved in distinct Late Cretaceous–early Eocene and late Oligocene–early Miocene extensional pulses, the first during collapse of gravitationally unstable upper plate assemblages and accompanied by trench-directed (top-NE) lower plate extrusion and the second corresponding temporally, spatially, and in character with core complex formation in the SW United States. The line between schist and core complex belts is blurred by the recent discovery of schist within 40 km of the nearest core complex and containing synkinematic Miocene intrusions, a hallmark of SW U.S. core complexes. The history of schist assembly, metamorphism, and exhumation provides the most complete field-based record of thermo-mechanical processes, subduction erosion and tectonic underplating in particular, that operated during a shallow subduction event. Future cross-disciplinary investigations of, and comparisons between, the schist and other possible ancient (e.g. Swakane gneiss, Sanbagawa belt, Qiangtang terrane) and modern (e.g. Cascadia, SW Japan, central Mexico, Chile) shallow subduction zones will yield new insights into the tectonic and petrologic processes that operate within such systems.
