This study explores the identity work carried out by three female owner‐managers in creative industry businesses, identified in Government reports as a discriminatory industrial sector for women in the UK. Through the development of narratives by the owners and other participants, observation of practice and review of online and offline materials, three cases emerged. These showed overlapping, different identities developed and performed through identity work. Each presented rational and logical persona as business leaders despite observation showing extensive use of intuition and gut feeling in both creative and entrepreneurial aspects of the business. Intuition and gut feeling were seen as inappropriate at work as they belonged to the home sphere, emotionally based and therefore automatically unreliable. While occupying male stereotypes and avoiding the female realm of emotion at work, these women expressed femininity through their emphasis on the maternal, ‘being a good mother' as a desired ideal being embedded in work as well as home practice.  相似文献

《Risk analysis》2018,38(10):2193-2207
Social diffusion of information amplifies risk through processes of birth, death, and distortion of message content. Dread risk—involving uncontrollable, fatal, involuntary, and catastrophic outcomes (e.g., terrorist attacks and nuclear accidents)—may be particularly susceptible to amplification because of the psychological biases inherent in dread risk avoidance. To test this, initially balanced information about high or low dread topics was given to a set of individuals who then communicated this information through diffusion chains, each person passing a message to the next. A subset of these chains were also reexposed to the original information. We measured prior knowledge, perceived risk before and after transmission, and, at each link, number of positive and negative statements. Results showed that the more a message was transmitted the more negative statements it contained. This was highest for the high dread topic. Increased perceived risk and production of negative messages was closely related to the amount of negative information that was received, with domain knowledge mitigating this effect. Reexposure to the initial information was ineffectual in reducing bias, demonstrating the enhanced danger of socially transmitted information.  相似文献

We evaluate the strategies of the emerging market firms in the context of nascent industries. We use the Indian solar power industry as the empirical setting, against the backdrop of the evolution of the global industry, While in traditional industries emerging market firms learn from advanced economy multinational enterprises (MNEs) and slowly upgrade their capabilities, in the intensely competitive environment of nascent innovative industries, emerging market firms are exposed to global competition in their home market right from the early years. This shortens their catch-up clock. As a result, their long-term survival depends on their ability to catch-up fast, both in output and innovation capabilities. In the solar power industry, we find that innovations stem, in the main, from advanced economy firms. Further, Chinese firms are beginning to move from cost-based imitation to innovation. In contrast, with a few key exceptions, most firms in the Indian solar industry remain locked within a narrow niche of downstream site-based installation. Their operations are opportunistic, short term, and without specific catch-up goals, a scenario that does not bode well for the industry's future in India.  相似文献

利用空间计量方法分析我国产业集聚对农业净碳效应的影响及其空间溢出效应,结果表明:2018年我国各省区农业净碳效应存在明显差异且两极分化严重;与2000年相比,各地农业净碳效应已出现均衡化趋势,整体梯度差异逐渐趋于收敛,高值省份数量增加且变化较大,低值省域数量减少且变化不大。产业集聚与农业净碳效应均存在空间自相关性,二者之间呈现“正N”型关系,即随着农业产业集聚程度的不断提升,农业净碳效应表现出“先增、后减、再增”的三阶段变化特征;从实际影响来看,区域内产业集聚度每提升1个百分点可促使农业净碳效应量增加1.621%;除此之外,农业公共投资、农业产业结构、区域经济发展水平等变量也表现出了一定的正向效应但作用力度要明显偏弱。产业集聚对农业净碳效应具有显著的溢出效应,并表现为区域间溢出和区域内溢出。具体而言,邻近地区产业集聚度每提升1%可促使本地农业净碳效应增加2.286%,而本地产业集聚对邻近地区产生影响后因受反馈作用自身农业净碳效应还会额外增加0.060%。  相似文献

In interviews with members of Britain’s Civil Defence Services, experiences of Cold War voluntarism are recalled in different ways. Some remembered their desire to help defend their nation and local community. Others remembered making a leisure choice that had little connection to the potential nuclear war the organization was ostensibly preparing for. No one provided a well-developed account of civil defence’s ability to provide a defence against the effects of a nuclear war. Popular memory theorists suggest cultural discourse limits the ability of individuals to narrate stories that do not align with culturally valued frameworks: in this case, dominant understandings of civil defence as at best ridiculous or at worst dangerous were established in the 1980s. This article argues that memories of civil defence voluntarism in the 1950-60s have been shaped by these discourses, but that individuals were able to express the different meanings civil defence had in their lives in ways that provide a more nuanced and holistic picture of the intersections of leisure, service and sociability that made up civil defence. As such, it argues that oral history allows us to understand the various ‘horizons of possibility’ that made up individual experiences of the Cold War.  相似文献

ABSTRACT

The growing commercialisation of migration, often through a multiplicity of labour market intermediaries, is an issue of increasing academic interest. We seek to contribute to an emerging research agenda on the migration industries by exploring how one of the key actors that constitutes it, recruitment agencies, sits at the nexus between flexible labour market structures and migrant labour. Interviews with U.K. labour providers and low-wage employers form the evidence base for an analysis of the strategies developed by recruiters to derive commercial gain from connecting the so-called ‘supply’ and ‘demand’ sides of the flexible international labour market. We seek to contribute to understandings of the analytical categories within migration systems by illustrating how the migration industry interacts with other key stakeholders to structure international migration.  相似文献

农村三产融合是一个由多种要素组成的系统工程。研究基于对贵州花溪区批林村的田野调查,发现:目前批林村对三产融合进行探索的电农融合、工农融合和文旅融合项目在实施过程中存在一些阻碍,具体包括发展资金较为匮乏,基础设施难以建设;技术渗透能力不强,新型产业难以发展;村落建设人才短缺,项目规划难以推进;三产融合程度较浅,产业增值难以实现;利益联结机制欠缺,农民利益难以保障等。针对批林村现实存在的典型问题,基于系统工程思想的指导,研究为三产融合振兴民族村落构建出以下发展路径:一是完善系统顶层设计,统筹三产融合发展思路;二是精准定位发展要素,抓住三产融合关键环节;三是合理布局结构关系,优化三产融合整体功能;四是创新融合发展方式,实现三产融合系统升级;五是加强后续保障机制,促进三产融合稳步运营。  相似文献

有效快速的核事故早期应急决策,是核电站发生核事故后最后一道必要的屏障,因此决策的快速性与有效性至关重要。文章先构造效用函数,求出决策者的乐观系数,将决策判断矩阵中的区间值与模糊值精确化;在此基础上建立了个体与群体的决策模型,以提高决策的有效性。同时根据排序结果,构造群体与个体之间一致性判断矩阵,并根据判断矩阵进行交互与修改,使专家内部快速达成一致。最后通过算例说明方法的可行性。  相似文献

In this article, a classification model based on the majority rule sorting (MR‐Sort) method is employed to evaluate the vulnerability of safety‐critical systems with respect to malevolent intentional acts. The model is built on the basis of a (limited‐size) set of data representing (a priori known) vulnerability classification examples. The empirical construction of the classification model introduces a source of uncertainty into the vulnerability analysis process: a quantitative assessment of the performance of the classification model (in terms of accuracy and confidence in the assignments) is thus in order. Three different app oaches are here considered to this aim: (i) a model–retrieval‐based approach, (ii) the bootstrap method, and (iii) the leave‐one‐out cross‐validation technique. The analyses are presented with reference to an exemplificative case study involving the vulnerability assessment of nuclear power plants.  相似文献
