William James (1919) characterises hypotheses as either live or dead. A hypothesis is live when it is taken into account as a ‘real possibility’. We follow James’ suggestion to not attribute intrinsic properties to hypotheses, but rather investigate how they came into being and look at the effects they generate. Expectations of digital technologies are a topic of vivid debate in the insurance industry. Before these expectations can become ‘live’, they have, in the first place, to be generated by market devices. We investigate how the reinsurance blogpost platform Open Minds functions as an ‘expectation generation device’ on the future of insurance markets. Combining Beckert’s work on the role of fictional expectations with the pragmatist turn in sociology of markets, we propose to study ‘expectation generation devices’, provoking expectations on economic markets. In our empirical analysis, we demonstrate the explicit fictional character of the Open Minds contributions, and analyse how a contained space of openness is generated to provoke expectations. We demonstrate how Open Minds can become live through circulation to other expectation generation sites in the insurance industry and beyond. We conclude by reflecting on the importance of expectation generation devices as a particular type of market devices.  相似文献

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

According to the statistics of the World Health Organization, an estimated 17.9 million people die from cardiovascular diseases each year, representing 31% of all global deaths. Continuous non-invasive arterial pressure (CNAP) is essential for the management of cardiovascular diseases. However, it is difficult to achieve long-term CNAP monitoring with the daily use of current devices due to irritation of the skin as well as the lack of motion artifacts suppression. Here, we report a high-performance skin-like optoelectronic system integrated with ultra-thin flexible circuits to monitor CNAP. We introduce a theoretical model via the virtual work principle for predicting the precise blood pressure and suppressing motion artifacts, and propose optical difference in the frequency domain for stable optical measurements in terms of skin-like devices. We compare the results with the blood pressure acquired by invasive (intra-arterial) blood pressure monitoring for >1500 min in total on 44 subjects in an intensive care unit. The maximum absolute errors of diastolic and systolic blood pressure were ±7/±10 mm Hg, respectively, in immobilized, and ±10/±14 mm Hg, respectively, in walking scenarios. These strategies provide advanced blood pressure monitoring techniques, which would directly address an unmet clinical need or daily use for a highly vulnerable population.  相似文献

修辞格在广告英语中的运用   总被引:1,自引:0,他引:1  
广告英语是一种有别于普通英语语篇的独具一格的应用文体语篇,广告英语的艺术感染力和社会经济效益取决于其语言的独特性。广告英语的成功在很大程度上取决于其修辞的魅力。广告英语的修辞魅力主要通过广告英语语篇在语音、词汇和句法三个层面的辞格运用来表现。  相似文献

英汉互译中衔接手段的合理转换是实现译语语篇连贯的保证。然而在翻译实践中往往存在着转换失当的情况,从而影响了译文的连贯,甚至造成严重的错误。本文通过对一些翻译实例的分析,阐述造成翻译失当的原因,指出衔接手段合理转换对实现译文语篇连贯的重要性。本文还探讨了衔接手段转换的若干方法。  相似文献

Social media are increasingly important in protest movements for communication and organization. As such, scholars should consider these ephemeral messages as a tool for understanding such movements’ rhetoric. This article draws on Kjeldsen’s method for the critique of visual political rhetoric and adds consideration of intertextuality, synecdoche, and metaphor to demonstrate a method for the rhetorical analysis and a critique of Internet memes as visual, political rhetoric. The Pepper Spray Cop meme arising from Occupy Wall Street is presented as a case-study example. The article considers the centrality of the intertextual nature of memes as a unique form of visual rhetoric in activist contexts and contributes to the literature on user-generated and activist rhetoric.  相似文献

词的内涵意义是基于概念之上的意义,它总能引发出一种甚至多种联想:同一个词的内涵意义因人、因时、因文化而异,有的甚至大相径庭。因此,要准确地把握词的内涵意义需结合多种因素。另一方面,词的内涵意义的表现方式也复杂多样,而最常见的是与一些修辞手段的结合,从而取得特殊的修辞效果。  相似文献

言语交际。信息传递,不都是简单的、单向的、固定的、一次性的。更多的。因此而更有现实意义和理论价值的,乃是那些复杂的、双向的、随机的、多次传递方能完成的。因此,判定某处修辞是成功的还是失败的,必须考察其在一个复杂的修辞流程中所起的作用,视其所造成的到底是正反馈还是负反馈。如若其所造成的是正反馈,那么,不管它多么生动、形象,都是失败的修辞;如若造成的是负反馈,那么,不管它多么朴拙、背谬,都是成功的修辞。  相似文献

The ubiquity and educational potential of mobile applications are well acknowledged. This paper proposes six theory-based, pedagogical strategies to guide interaction design of mobile apps for young children. Also, to augment the capabilities of mobile devices, we used a humanoid robot integrated with a smartphone and developed an English-learning app that applied the design strategies to this environment. Our observations of children's one-on-one use support the promise of the strategies and the combined use of robots and mobile devices to be a viable option to help optimize mobile learning.  相似文献

研究了以(PPQ)2Ir(acac)为客体,分别以PFO、PVK、PFB和PFG四种不同聚合物为主体掺杂体系的光谱性质.各种材料的紫外-可见吸收光谱和光致发光光谱的性质表明PVK和PFO与客体之间可以发生有效的能量转移.此外,与光致发光谱不同,发光器件电致发光光谱有较纯的红光发射,表明除了能量转移之外,电荷捕获也是实现器件红色发光的主要原因之一.  相似文献
