City of the Spectacle: White Night Melbourne and the politics of public space

Public policy frequently is utilised as a medium to facilitate or restrict access to public space, and to privilege economic priorities. In this context urban arts festivals are used as a means to generate dominant narratives of place and use of public space. Urban arts festivals generate spaces of spectacle and wonder, and are often used as marketing strategies to revitalise urban economies and differentiate cities one from another on the global stage, engendering a commodification of place. The present paper explores this tension through an examination of the role of urban arts festivals in spatial politics. White Night Melbourne is the first Australian iteration of the Nuit Blanche International, an international network of all-night arts festivals. It is used as a case study to explore the impact of an urban arts festival on the spatial politics of Melbourne. A theoretical basis is established using the frame of Guy Debord's ([1967] 1994) The Society of the Spectacle, as well as the concepts of ‘assemblage’ and ‘expressivity’.     

Encountering The Night with Mobile Methods

Nightlife settings both facilitate urban sociality and act as sites of social conflict, however little research has focused on experience and encounter in these places. This paper addresses this gap in the context of night‐time economic planning and recent research on encounter. The use of mobile methods in nightlife spaces is shown to garner a more nuanced understanding of how forays into planned night‐time spaces are experienced and understood by people using those spaces. I argue that emplaced, mobile methods unveil complex narratives of place, revealing prejudices and discourses at play in place. These narratives begin to erode privileged images of the city shaped by increasingly neoliberal governance and other cultural intermediaries, and draw out the potential of these methods to improve the lived inclusivity of place.     

South American heartland: the Charcas, Latin American geopolitics and global strategies

Mackinder's 1904 'geographical pivot of history' concept, subsequently developed into his famous 'Eurasian heartland thesis', marginalizes South America, yet his ideas have attracted considerable interest there, including interpretations (and fantasies) of a 'South American heartland'. This paper examines the reception of Mackinder's ideas in Latin American geopolitics and how his heartland thesis was adapted for the South American context. It traces the roots of this adaptation in earlier South American geopolitical writing, and examines these ideas of counter-insurgency policies and global geopolitical strategies, analysing their relationship to military and anticommunist perspectives.     

广东从化地区晴朗夜间露水凝结研究

在全球变化环境压力下,非干旱地区露水研究对露水沉降规律的认识及其生态效应研究具有重要意义.文中以非干旱地区为研究区域,采用布片法对晴朗夜间的露水进行了研究.结果表明,各个季节的露水发生频率和露水凝结量明显受季节变化的影响,不同季节露水发生和凝结各不相同.秋季露水发生频率较高,达80﹪,春季露水频率较小,不到30﹪.就平均每晚露水量看,夏季和秋季无明显差异,但都显著高于冬季和春季.夜间最大露水量发生在秋冬季,大约0.23 mm.此外,下垫面对露水具有重要影响,不同下垫面上凝结的露水量不同,有植被覆盖的下垫面在夏秋季节凝结的露水量显著高于混凝土上凝结的露水量.研究结果说明,在环境管理中,应增加地表植被的覆盖,促进露水凝结.     

长沙降水中稳定同位素的昼夜差别

基于长沙地区降水稳定同位素的实测数据,对不同季节(暖半年、冷半年)、不同降水类型(对流降水、平流降水)、不同降水强度下昼、夜降水中稳定同位素的变化特征进行分析和比较,旨在揭示昼夜降水中稳定同位素的差异及其影响因素,深化对季风区降水稳定同位素变化规律的认识.结果表明:降水中δ18O在暖半年时段夜间比白天偏正,而在冷半年时...     

丹顶鹤越冬期在人工湿地的夜栖分布

在盐城国家级自然保护区人工湿地内,通过对丹顶鹤越冬期间夜栖地的调查,得出鹤群夜栖分布及其动态规律,并提出对该种群与夜栖地的管理措施。该项工作主要借助望远镜、GPS.照相机,采用直接计数法统计数量和利用文献资料数据。结果表明:人工湿地中丹顶鹤的夜栖分布随着环境的改变而改变,其中安全度和水位为其主要限制因子。因此控制人工湿地冬季水位,保护栖息环境不受人为影响是丹顶鹤安全越冬的主要保护措施。     

Globalization and the Balkanization of States: The Myth of American Exceptionalism

Abstract

This paper proposes different strategies for teaching social studies in an integrated manner using Main Street as a laboratory. The paper consists of two parts. Part one is devoted to a discussion of the empirical study; the second part focuses on strategies for integrating Main Street into the K through 12 setting. Although data are presented from fifteen smalltown parish Main Streets, Abbeville and Columbia are discussed in detail around Francaviglia's time, space, and image elements. The suggested strategies for integrating Main Street into the curriculum are rooted in K through 12 teacher experiences from three Louisiana Geography Education Alliance (LaGEA) Summer Institutes held in 2001, 2002, and 2003.     

厌氧折流板反应器处理粪便污水的试验研究

在有效容积为32 L的四格室厌氧折流板反应器中,进行了处理粪便污水的研究.当进水ρCOD＝1.270～1.790 g/L、pH＝7.33～8.45、tHRT＝48 h时,研究发现:接种污泥经长期驯化的ABR反应器在启动初期COD去除率即能达到75%以上,稳定运行时去除率可达90%左右;pH值沿格室逐渐升高,出水pH值基本稳定在6.8～7.2之间;传统的ABR对NH3-N的去除率仅有20%左右,需结合好氧工艺来进行进一步的脱氮研究.
