Mediating good food and moments of possibility with Jamie Oliver: Problematising celebrity chefs as talking labels

This paper explores the powerful and mediating role of celebrity chefs over audience relationships with food through analysis of Jamie Oliver and his recent series Save with Jamie. The paper firstly situates the role of celebrity chefs theoretically, defining them as ‘talking labels’ who may act both as knowledge intermediaries and boundary objects to connect audiences with food in multiple ways. Here chefs actively construct and mediate discourses around ‘good food’. As trusted, credible, well-liked public figures, chefs step into out private home spaces through our televisions to convey food information in a charismatic, entertaining and accessible way. Like traditional food labels, chef’s words can be ‘sticky’ and take hold in public imaginations in a way that goes far beyond the capacity of food products labels. Yet the relationship between chefs and audiences is far from straightforward and so the paper secondly aims to explore how these talking labels are understood and ‘used’ by audiences in their everyday food practices. Drawing selectively from a large scale audience survey (n = 600) as well as the series, Save with Jamie, this paper reveals the different ways that audiences ‘talk back’ to chefs both positively and negatively to create moments of simultaneous possibility and resistance for audience relations with food. This revealed complex relationships between audiences, chefs and food. It also suggests that the powerful work on celebrity chefs functions as part of a new mediated mechanism within today’s food governance.

浅谈高温高压实验地球科学:方法和应用

在过去的二十多年间,高温高压实验地球科学研究得到了蓬勃发展,凭借其高度的灵活性和易于与其他分支学科相结合的优点,在很多不同的研究领域中都取得了令人瞩目的成果,并已发展成为国际地球科学的前沿领域和重要方向之一,同时也是固体地球科学最强有力研究手段之一。相比之下,国内的高温高压实验地球科学研究还显得相对比较薄弱,相关系统性的认识还有待增强。本文对高温高压实验研究的发展历程、方法原理、仪器设备以及在地球科学研究中的一些应用进行简单的介绍,旨在让更多的国内学者对这一领域有更深入的了解。     

Globalising knowledge networks: Universities,diaspora strategies,and academic intermediaries

As diaspora strategies have become an integral aspect of national economic development strategies, so too have universities begun to formally identify and mobilise diasporic scientists, researchers and scholars in an effort to create global knowledge networks. This paper will identify this new role for diasporic academics. It begins by emphasising the increasing internationalisation of the academic labour market, arguing that an increasing number of researchers have multiple national affiliations and relationships. It shows how diasporic academics have become central to the creation of global knowledge networks. These knowledge networks derive from multiple sources including the institutional ambitions of universities who are seeking to expand their research remits in increasingly resource constrained environments, international and national funding bodies who are increasingly focused on research ‘grand challenges’, and the aspirations of individual researchers for whom global networks are increasingly important to successful careers.

基于新疆地震知识的地震预报专家系统的研究

依据新疆南北天山带地震预报实践中b值和η值的异常判据,对运用于地震预报专家系统（ＥＳＣＥＰ）测震学方法的主要异常判别指标进行了个性,并对个性前后的计算结果进行了对比分析,对预报效能进行了评价。结果表明,个性后的专家系统知识库预报效能明显提高,虚报和漏报率明显下降,预报效能明显提高,虚报和漏报率明显下降,预报效能通过检验,说明修改后了专场主家系统知识库更适合新疆地区中短期地震预报。
