FPSO爆燃事故加强机制分析     

张兴东  张彬  丰伟东  吉玛 《上海海事大学学报》2020,41(4):103-107

为探究海上浮式生产储油卸油船(floating production storage and offloading，FPSO)爆燃事故加强机制，采用计算流体力学(computational fluid dynamics, CFD)对FPSO爆燃事故进行数值模拟。模拟结果表明，在拥塞度较大的钢架结构区域，火焰速度和爆燃压力急剧增大。为进一步探究复杂钢架结构和管系对爆燃事故的加强机制，搭建半开敞管道甲烷 空气爆燃实验系统。实验结果表明，在爆燃过程中复杂钢架结构和管系能够诱导火焰产生强烈的湍流作用，加快未燃气体的燃烧速度，导致爆燃事故后果加强。结合数值模拟结果与实验结果，为FPSO爆燃事故防治给出建议。  相似文献   

Culturalisation and devices: what is culture in cultural economy?     

Lizzie Richardson 《Journal of Cultural Economy》2019,12(3):228-241

Theorisation of culture is often absent from research on production in the creative and cultural sector. Further, cultural production has been largely untouched by the insights of the cultural economy approach. Culturalisation is a means of addressing the question of what constitutes culture and thus a cultural (economy) approach. It is the process by which culture and cultural production combine in the ‘operationalisation of the real.’ Culturalisation underpins much scholarship in this journal by posing the (economic) real as a problem of definition in order to illustrate the operations involved in its temporary resolution. The implications of this position need further addressing. There is a feedback between culture as a problem of definition and a cultural approach. Devices can interrogate the relationship between processes of cultural definition and the conceptual parameters of a cultural economy approach. Workshopping, projects and events are put forward as cultural devices emerging from a 10-month ethnography of literary performance in Bristol, England. This illustration shows firstly, how culturalisation occurs in a designated cultural sector to contingently realise culture; and secondly, the implicit logic of cultural economy as culturalisation, typified by the device as method, so as to open a debate concerning its implications.  相似文献   

消费时代澳门半岛滨水空间形态重塑     

李沁茹  吴尧 《中国名城》2020,(5):26-32

随着消费社会的深化发展,现代消费已成为影响城市空间形态演化的重要因素。以此为出发点,以消费文化的视角来考察城市空间,揭示20世纪80年代以来澳门半岛滨水空间形态的演化特征。研究表明:消费时代,城市主要根据经济诉求组织空间的生产,借助资本的熔铸,澳门半岛滨水空间建设呈现出博彩旅游化、高层豪宅化和空间巨构化等特征,并最终实现空间形态的重塑。在此基础上进行批判性反思,如城市消费空间与传统城市意象的协调发展、城市空间的阶级化和滨水空间的公共性等问题。  相似文献   

Between business and morality: cultural politics in independent bookshops in China     

Zheng Liu 《Journal of Cultural Economy》2020,13(4):461-474

ABSTRACT

This article investigates how cultural businesses may facilitate contentious political activity in authoritarian contexts. Existing research in Western liberal democracies has shown the widespread political activism of actors in the cultural and creative industries. Whether such activism exists in authoritarian society, how it may differ in character and form, and what implications this will have for our understanding of relations between business, politics, and culture in authoritarian countries remain to be addressed. Drawing on data collected from 55 ‘independent bookshops’ in China, I illustrate how these organisations perform ‘cultural politics,’ a type of political participation in which actors employ mainly symbolic means to express social and political concerns. The organisations’ economic relations and conditions facilitate their efforts to create spaces in which contentious questions can be raised, sensitive topics explored, and alternative ideas expressed, despite the Chinese state’s political regulation of the cultural sphere. The finding of the economic embeddedness of cultural politics sheds new light on our understanding of the political economy of cultural businesses in contemporary China.  相似文献   

我国冰雪文化消费空间的构建及其发展路径     

司亮  萧林静  陈淼  程文广 《沈阳体育学院学报》2020,(1):94-100,109

国务院印发《完善促进消费体制机制实施方案(2018-2020年)》文件中指出"积极培育‘冰雪运动’体育消费新业态"。在此背景下,立足于消费空间视角,以冰雪文化成为空间消费品为切入点,针对我国冰雪文化消费不足的问题,提出了冰雪文化消费空间的概念。研究发现,冰雪文化消费空间不仅具有经济、社会、文化的内涵特征,而且其体验化、商业化、休闲化、娱乐化的典型特征与文化艺术化、信息网络化、全球国际化的非消费要素相互共存,在空间消费活动中逐渐构建成宏观、中观、微观层面的空间体系。最终,在空间生产语境中,基于"生产-消费"的逻辑,提出了将冰雪文化消费空间正式纳入"生产-分配-交换-消费"的过程追求再生产的发展路径。  相似文献   

Scope and Difficulties of the Transmedia Practice. A Case Study on the Spanish PSM System     

Ainara Larrondo Ureta 《Journalism Practice》2020,14(8):991-1007

ABSTRACT

According to a growing volume of academic literature on the subject, transmedia fiction and non-fiction production is now one of the main areas driving innovation in media companies, thanks to the improvements it brings in numerous interconnected fields: narrative and content, management and productive strategy, brand promotion, etc. In this context the article focuses on transmedia linked to public broadcasting companies, starting with a qualitative study based on interviews with expert professionals from thirteen corporations in Spain, one operating at the national level (RTVE) and twelve at the regional level (A Punt Media, CARTV, CCMA, CRTVG, CMM, EITB, EPRTVIB, RTVM, RTPA, RTVA, RTRM and RTVC). The results show how professionals view the concept of transmedia production, its advantages, disadvantages and the challenges it poses, which depend on these corporations’ service and relationship with audiences. As the conclusions state, the keys factors for understanding the professional transmedia strategy of public broadcasting corporations are found in the characteristics of today’s media market, which is suffering from budget cuts and growing competition.  相似文献   

Understanding China as practicing Chineseness: selected cases of Vietnamese scholarship     

Chih-yu Shih 《Inter-Asia Cultural Studies》2018,19(1):40-57

The notion of post-Chineseness is enlisted to analyze Vietnamese Sinology as a comparative agenda. Post-Chineseness refers to the cultural preparation and the political process of mutual acknowledgement among those who consider one another sharing (some kind of) Chineseness, practically defined according to the context and its trajectories, at each time and each site. Chineseness can thus have various, if not entirely irrelevant, meanings. Vietnamese Sinologists have relied on different kinds of post-Chineseness to make sense of their relationship with the encountered Chinese to select and determine the mode of self-understanding, the purpose and a strategy to reconnect, and the normative criterion to assess and manage the relationship. Chinese Vietnamese are significantly less numerous than Chinese Malaysian, Thai, and Indonesians. However, the history of Vietnam is considerably closer to China than are those of Korea and Japan, in terms of length of merger. The post-Chineseness of Vietnamese scholarship therefore complicates its role-identity vis-à-vis China, intellectually as well as practically.  相似文献   

体育用品对外贸易大国与对外贸易强国的理论探析     

杨文刚  杨明  孙茜 《武汉体育学院学报》2020,54(6):54-60

对体育用品对外贸易大国和对外贸易强国的概念进行了界定。从贸易主体、贸易内容、贸易利得和贸易市场4个方面分析了体育对外贸易大国的特征。总结了体育用品对外贸易强国的特征：依托体育用品制造产业全球价值链发展并实施治理、拥有国际知名品牌、拥有良好的原产国形象、拥有行业领先企业、创新能力强、主导国际经贸规则与标准制定等。在此基础之上对体育用品对外贸易大国与对外贸易强国的联系与区分进行了阐释和分析，认为推进我国由体育用品对外贸易大国向对外贸易强国转变演进的实施体系是一个系统工程，该系统存在三个维度：第一维是"双力维"，即压力维与动力维；第二维是"要素维"，即培育、引进高级生产要素；第三维是"竞争维"，即竞争与超越。  相似文献
