This paper studies how people reason about and make sense of human-made global warming, based on ten focus group interviews with Norwegian citizens. It shows that the domestication of climate science knowledge was shaped through five sense-making devices: news media coverage of changes in nature, particularly the weather, the coverage of presumed experts' disagreement about global warming, critical attitudes towards media, observations of political inaction, and considerations with respect to everyday life. These sense-making devices allowed for ambiguous outcomes, and the paper argues four main outcomes with respect to the domestication processes: the acceptors, the tempered acceptors, the uncertain and the sceptics.  相似文献

Effect of magnesium ions on the binding of bilirubin to erythrocytes of different mammalian species, namely, human, buffalo, goat and sheep was studied. Increase in the concentration of magnesium ions led to a gradual increase in the erythrocyte-bound bilirubin in both human and buffalo erythrocytes whereas in sheep and goat erythrocytes, the pronounced increase was found beyond 2.0 and 2.7 mM MgCl2 concentrations respectively. Percentage increase in erythrocyte-bound bilirubin was found highest in human erythrocytes followed by buffalo and sheep erythrocytes and minimum in goat erythrocytes. These differences in the binding of bilirubin to different mammalian erythrocytes can be attributed to the differential shielding effect of metal ions which involves the masking of negatively charged phosphate of phospholipids found on the erythrocyte surface.  相似文献

This article deals with the contribution made by domestication research to our understanding of information and communication technologies (ICTs) in everyday life, especially in the home. It first provides a sense of the diversity of research in this tradition and how this is evolving. The article then reflects upon and illustrates different elements of research in this tradition, providing examples of how these help to explain patterns of ICT experience, the way people evaluate that experience, and what bearing it has on their lives. To contextualize domestication research further, it considers overlaps with other traditions of research before moving on to the core, and the range of methodologies that have been employed. Finally, the article examines some of the general insights from domestication research, as well as more specific applications to the commercial and policy fields.  相似文献

Abstract

This exploratory study investigates the encounters and everyday experiences with the Facebook algorithm of 18 informants in Yangon, Myanmar. It draws on domestication theory and research on algorithms to understand how users come to use and respond to Facebook. Findings showed that their particular perception of Facebook algorithm—Friends funnel information—informs their domestication process, wherein they add strangers as Friends to draw more information flows to their News Feeds.  相似文献

随着世界水危机日益加剧,国际河流水资源的合作开发日显重要。本文将国际河流水资源合作开发系统视为一个政治、经济、生态、社会、文化复合耗散系统,在对系统环境及行为主体进行分析的基础上,运用解释结构模型(ISM)划分了该系统的内部子系统结构,指出沟通协调子系统是影响系统运行的最核心部分,水资源载体子系统是系统运行的基础。相关利益主体对国际河流水资源合作开发的利益诉求差异、合作开发带来的生态破坏问题、信息共享力度不够、政治争端、管理效率递减等问题都会使得系统熵值增加,阻碍合作开发活动的开展,而良好的政治局势、人财物等方面支持、生态修复及补偿机制、国际涉水制度的完善等则会使系统熵值减少,促进合作的有效开展。在根据熵增和熵减影响因素设计指标体系的基础上,本文构建了国际河流水资源合作开发系统熵模型,并对不同总熵值下应采取的措施给出了建议。  相似文献

The Natuurkundig Genootschap der Dames (Women's Society for Natural Knowledge), formally established by and for women, met regularly from 1785 to 1881 and sporadically until 1887. It challenges our stereotypes both of women and the physical sciences during the eighteenth century and of the intellectual interests open to women in the early European republics. This essay aims not simply to identify the society and its members but to describe their pursuits and consider what their story adds to the history of Western science. What does this society's existence tell us about the relationship between women and early science in general and about science and society in the Dutch setting in particular? Science and gender look rather different when observed through the activities of the immensely prosperous women of Middelburg, citizens of one of the most highly literate Western countries. The elite lives of the first-generation members of the women's society also offer us a glimpse into the early domestication of science, a process vital to its acceptance and assimilation.  相似文献

本文采用语料库分析方法,对双语文本进行对齐、标注并建库,使用语料库检索软件检索出各类文化负载词,并对其翻译策略进行分析和统计。数据显示,葛浩文对《红高粱家族》中文化负载词的翻译主要采取归化的翻译策略,这一结论既符合中国文学英译的主流模式也符合译者的翻译思想。通过对各类文化负载词的观察,发现译者对于难以寻找对等词的物质文化负载词和容易产生文化冲突的社会文化负载词和宗教文化负载词更倾向于使用归化策略,而为了保留原著的语言特征和异国情调,在语言文化负载词的翻译中大量采用了异化的策略。  相似文献

Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed. Soybean domestication involved parallel increases in seed size and oil content, and a concomitant decrease in protein content. However, science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes. Here, re-sequencing data from >800 genotypes revealed a strong selection during soybean domestication on GmSWEET10a. The selection of GmSWEET10a conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content. The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans. Moreover, GmSWEET10b was found to be functionally redundant with its homologue GmSWEET10a and to be undergoing selection in current breeding, leading the the elite allele GmSWEET10b, a potential target for present-day soybean breeding. Both GmSWEET10a and GmSWEET10b were shown to transport sucrose and hexose, contributing to sugar allocation from seed coat to embryo, which consequently determines oil and protein contents and seed size in soybean. We conclude that past selection of optimal GmSWEET10a alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEET10b may further improve the yield and seed quality of modern soybean cultivars.  相似文献

目前,中国的流域水资源配置主要基于集体理性假设,从水资源单一决策主体的角度出发,追求流域利益最大化,由于未能充分考虑各用水主体的协商意愿和利益诉求,容易使得用水主体对配水方案的满意程度不高,方案执行阻力较大。为此,本文定义了用水主体满意度,来衡量用水主体对水资源配置方案的满意程度,在此基础上,提出了用水主体满意度原则,并将其数学量化为最低满意度函数和差异满意度函数,为用水主体参与水资源配置决策提供协商渠道。最后,结合水资源分配基本原则和用水主体满意度原则,构建了流域水资源优化配置模型,并进行了算例验证。结果表明,①所建模型符合流域水资源配置的公平性原则;②各区域对于分水方案的满意度水平与自身决策权重存在正相关匹配关系;③最低满意度设置较低时,流域水资源管理者更侧重于分水活动的高效性;反之,更侧重于分水活动的公平性。  相似文献
