Platform nations     
This article introduces the concept of platform nations to capture an important recent shift in the way nations and nationalism operate in the public domain. If the rise of the internet initially led to a weakening of state control over public expressions of national belonging, the growing monopoly of platforms enables states to reassert control over national imagination, while also opening doors for other political and corporate actors to interfere in the process. This shift appears to be contributing, at least in some parts of the world, to a disciplining of national imagination online, partially reversing the trend to greater democratisation seen in the early stages of the internet.  相似文献

One of the main debates regarding historical representation within digital media concerns narrative, particularly the difficulty in articulating it. Digital technologies are usually presented as opposed to linear, written narratives, which is of consequence to historical writing. Despite the many merits of scholarly approaches that try to circumvent this difficulty, the lack of theoretical understanding of the categories implied in such discussions is noticeable. To counter this, this article addresses the relationship between time, technics, and narrative. I contend that the challenges of crafting narratives in digital media conceal a problem pertaining to the relationship between time and technics. Drawing on Paul Ricoeur's work on narrative, Jimena Canales's studies of the history of science, Wolfgang Ernst's and Yuk Hui's discussions of technical temporality, and Bernard Stiegler's understanding of the relationship between time and technics, I argue that it is the temporality imbued in the workings of technical objects (such as computers) that renders them averse to narrative. In making this argument, I employ the notion of “counted time” (in contrast to Ricoeur's “narrative time”) to denote a temporal mode that, despite its intersections with social, human temporality, is alien to narrative.  相似文献

This study aims to provide a comprehensive examination of the evolution of regional science, a scholarly domain in the social sciences that applies analytical and quantitative approaches and methods to understand and address urban, rural, or regional problems. We conducted a bibliometric analysis of 8509 articles published in six regional science flagship journals (including the Journal of Regional Science, Annals of Regional Science, Regional Science and Urban Economics, Papers in Regional Science, Regional Science Policy and Practice, and International Regional Science Review) from 1958 to 2021. The analysis presents an objective data-driven and unprecedented visualization of the field's intellectual, social, and conceptual structure and trends from the beginning to the present. It also provides a rich portrayal of the epistemology of regional science and illuminates matters related to regional science education and training. We find that regional science has moved well beyond its origins, shifting away from a heavy focus on theory and abstraction to modeling/simulation, empirical analysis, and policy research. We also find that there has been increasing attention to “people” in regions and the spatial characteristics of social problems, and some important shifts in the regional science community itself, particularly in terms of patterns of collaboration and the geography of scholarship. The findings of this paper provide implications for future directions of research and education for regional science.  相似文献

The fossil record suggests that modern human morphology evolved in Africa between 150,000 and 50,000 years ago, when the sole inhabitants of Eurasia were the Neanderthals and other equally nonmodern people. However, the earliest modern or near-modern Africans were behaviorally (archaeologically) indistinguishable from their nonmodern, Eurasian contemporaries, and it was only around 50,000-40,000 years ago that a major behavioral difference developed. Archaeological indications of this difference include the oldest indisputable ornaments (or art broadly understood); the oldest evidence for routine use of bone, ivory, and shell to produce formal (standardized) artifacts; greatly accelerated variation in stone artifact assemblages through time and space; and hunting-gathering innovations that promoted significantly larger populations. As a complex, the novel traits imply fully modern cognitive and communicative abilities, or more succinctly, the fully modern capacity for Culture. The competitive advantage of this capacity is obvious, and preliminary dates suggest that it appeared in Africa about 50,000 years ago and then successively in western Asia, eastern Europe, and western Europe, in keeping with an African origin. Arguably, the development of modern behavior depended on a neural change broadly like those that accompanied yet earlier archaeologically detectable behavioral advances. This explanation is problematic, however, because the putative change was in brain organization, not size, and fossil skulls provide little or no secure evidence for brain structure. Other potential objections to a neural advance in Africa 50,000-40,000 years ago or to the wider Out-of-Africa hypothesis, include archaeological evidence (1) that some Neanderthals were actually capable of fully modern behavior and (2) that some Africans were behaviorally modern more than 90,000 years ago.  相似文献

ABSTRACT

Geographers interested in how entrepreneurs perceive locational environments have studied their mental maps in several European countries, within the theoretical framework provided by behavioral approach. Such studies have typically employed quantitative techniques, but qualitative studies are relatively new to this line of research. In this article, I examine the mental maps of entrepreneurs in Italy by using a mixture of qualitative and quantitative methods. I present and discuss the qualitative outcomes of this research, focusing in particular on the explanatory location factors and the key influences on the mental maps of entrepreneurs. What emerges is the realization that entrepreneurs are far from being fully rational economic actors, who exploit optimally all information and who are driven only by objective considerations. Rather, their views are also affected by subjective factors, individual’s own insights, commonplaces, stereotypes, and prejudices, particularly with reference to the southern regions of Italy (Mezzogiorno), and of other peripheral areas.  相似文献

许多出土饱水木质文物因其降解严重、含水率较高,容易在脱水过程中出现不可逆的收缩变形以及开裂现象,从而遭到严重破坏。因此,饱水木质文物脱水方法的研究是文物保护工作中的重要课题。为探究风冷冷冻法对饱水木质文物脱水的效果,以一批无法复原的出土饱水木质文物为研究对象,在对其材种、含水率、基本密度及化学成分进行了测定和分析后,使用一台风冷电冰箱在-18℃条件下对样品进行了风冷干燥脱水处理,记录脱水时间和脱水效果,并分析了该方法的传质传热特点,证明了风冷干燥法用于饱水木质文物的脱水干燥能够取得良好效果,并且具有对文物干预小、适用性广、操作简便、成本低廉等优点,为饱水木质文物的脱水处理提供了一种新的思路。  相似文献

New social movement theories have been developed to address the organisational structures of activism in the age of digital platforms, but have tended to focus on structural questions rather than interpersonal dynamics. This paper engages with Bennett and Segerberg’s theory of connective action but uses a feminist lens to foreground the interpersonal dynamics between digitally equipped activists to develop a uniquely feminist account of connective action. It draws on Jo Freeman’s ‘tyranny of structurelessness’ to illustrate how informal organisation pervades new forms of connective action and continues to hamper the feminist movement. However, it also introduces and identifies the ‘feminist manager’ as an attempt to address the problematic practices of structurelessness and informality, and paves the way for consciously recognising the organisational structures required to advance the movement beyond consciousness-raising initiatives.  相似文献

In the area of cultural heritage, tourists’ experiences emphasise not only the moment and its personal nature but also socio-cultural traits. These experiences when expressed (social communications) are an important gateway to knowledge about tourists’ sense-making processes. This paper reports on the mediation between tourists and heritage sites via comments on a digital platform (TripAdvisor) about two Spanish tourist destinations with opposing characteristics and four heritage sites, which are analysed. The methodology used seeks to transcend the individual and anecdotal aspects of tourists’ comments. Indeed, the results obtained show the relevance of the humanisation and the discursive weight of heritage contexts in emotional/personal stories. Tendencies observed in non-regulated contexts confirm the role of a complex negotiation at cultural heritage sites and highlight the need to explore possible exchanges of sense in tourists’ encounters with such sites.  相似文献

The Gillard government's decision to reverse an election promise to not introduce a carbon tax prompted protest rallies around Australia during 2011–12. Beneath the hyperbole of critics who dismissed these protests as imitating US Tea Party extremism lies an intriguing possibility: that these are each examples of a new form of right-wing political expression enabled by structural changes in the media. This article considers the nature of the anti-carbon tax ‘people's revolt’ and its resemblance to the Tea Party. Both are a hybrid mix of top-down control and bottom-up grassroots populism whose emergence ‘outrage media’ facilitated. In a manner that echoes the support Fox News gave Tea Partiers, talkback radio in Sydney appears to have played a particular role shaping the identity, agenda and uncivil tone of the campaign against the carbon tax.

吉拉德政府决定背弃不征碳税的竞选承诺,在2011-12年引发了全澳大利亚的抗议示威。批评者将示威斥为对美国茶党极端主义的模仿。批评者夸张言辞的背后却是一种有趣的可能:此乃媒体结构变化所造成的、右翼政治表达的新形式。本文思考了反碳税“人民反叛”的性质,以及它与茶党的相似性。二者都是自上而下控制与自下而上草根民粹的混合,“愤怒的媒体”有利于它们的出现。就像狐狸新闻声援茶党那样,悉尼的对讲电台似乎在塑造反碳税运动的身份、议题以及粗暴的口吻方面发挥了特殊的作用。  相似文献
