曹雪芹的无神论思想在《红楼梦》前八十回中有大量体现,其中虽然写了许多神仙的故事,但是这些神仙的名字都叫茫茫大士,渺渺真人,空空道人,警幻仙姑;而地名则叫大荒山,无稽压,太虚幻境等等.曹的用意十分明确:这些不过是渺、茫、空、幻,荒诞的无稽之谈,属于"贾(假)语村言",和此书不记何年何代,地点可南可北一样,都是为了给此书蒙上一层虚无飘渺的色彩,以掩盖其现实严肃的政治内容.曹雪芹虽写了一系列神话故事,但一写到现实的和尚,尼姑,道士,道婆一类人物,大都采取揭露和批判的态度.与高鹗在后四十回中大量传播神权和因果报应得封建迷信思想,形成鲜明的对比.  相似文献

北京从金代海陵王营建中都,历金、元、明、清、民国,至今已建都近千年。在漫长的历史时期中,随着地区经济的发展和人口的增多,北京及其周边地区的生态环境不断被破坏,各种生态灾害愈演愈烈。自然灾害的加剧反过来又激化了社会矛盾,影响了历史的进程。本文对历史文献记载的生态灾害进行了回顾,就其原因及应对措施作了分析和探讨。  相似文献

The extent of economic losses due to a natural hazard and disaster depends largely on the spatial distribution of asset values in relation to the hazard intensity distribution within the affected area. Given that statistical data on asset value are collected by administrative units in China, generating spatially explicit asset exposure maps remains a key challenge for rapid postdisaster economic loss assessment. The goal of this study is to introduce a top‐down (or downscaling) approach to disaggregate administrative‐unit level asset value to grid‐cell level. To do so, finding the highly correlated “surrogate” indicators is the key. A combination of three data sets—nighttime light grid, LandScan population grid, and road density grid, is used as ancillary asset density distribution information for spatializing the asset value. As a result, a high spatial resolution asset value map of China for 2015 is generated. The spatial data set contains aggregated economic value at risk at 30 arc‐second spatial resolution. Accuracy of the spatial disaggregation reflects redistribution errors introduced by the disaggregation process as well as errors from the original ancillary data sets. The overall accuracy of the results proves to be promising. The example of using the developed disaggregated asset value map in exposure assessment of watersheds demonstrates that the data set offers immense analytical flexibility for overlay analysis according to the hazard extent. This product will help current efforts to analyze spatial characteristics of exposure and to uncover the contributions of both physical and social drivers of natural hazard and disaster across space and time.  相似文献

大规模地震后应急物资的高效保障是应急救援有效开展的必要前提。震后应急物资运输与配送包括从区域储备仓库和外围物资集散地运输到区域应急配送中心、由区域应急配送中心配送到各个受灾点两个阶段。应急物资保障具有持续时间长、需求紧迫性强和物资相对短缺等特点。本文以应急物资保障时效性与分配公平性为目标,建立了考虑多种运输方式、多时段动态的应急物资配送中心选址与运输配送路径优化的多目标规划模型,并基于此模型设计了一种带精英策略的非支配排序的遗传算法,以九寨沟地区地震灾难情景对模型进行实证研究,验证了模型和算法的有效性,以期为震后应急物资保障提供理论指导与决策支持。  相似文献

ABSTRACT

In May 2016, an enormous wildfire threatened the city of Fort McMurray, Alberta and forced the evacuation of all of the city’s residents. Outpourings of support teemed in from all across Canada and over the world, prompting the largest charitable response in Canadian Red Cross history. This paper examines Albertans’ response to the wildfire by exploring caring and helping behaviors as well as the role of social media in facilitating these remarkable charitable efforts. The paper uses mixed methods including an analysis of the most popular Tweets related to the wildfire and an Alberta survey collected months after the disaster. The analysis of tweets reveals that care, concern, and invitations to help were prominent in social media discourse about the wildfire. The analysis of survey data demonstrates that those who followed news about the wildfire on social media express higher overall levels of care and concern for those affected, which led to helping those impacted by the wildfire. The findings provide important insights about the role of social media in disaster relief and recovery as well as citizens’ civic engagement.  相似文献

Although the Chernobyl nuclear disaster happened in the Soviet Union in 1986, we still do not know how the most affected states – Ukraine and Belarus – have managed this tragedy since independence. Drawing on the concept of cultural trauma, this article compares Chernobyl narratives in Belarus and Ukraine over the past 28 years. It shows that national narratives of Chernobyl differ, representing the varying ways in which the state overcomes trauma. Our understanding of post‐communist transformations can be improved by analysing trauma management narratives and their importance for new national identity construction. These narratives also bring new insights to our vision of cultural trauma by linking it to ontological insecurity. The article demonstrates how the state can become an arena of trauma process as it commands material and symbolic resources to deal with trauma. In general, it contributes to a better understanding of how the same traumatic event can become a source of solidarity in one community, but a source of hostility in another.  相似文献

以台风“山竹”为例,基于微博数据,综合运用社会网络分析、文本情感分析等方法,分析网民情感传播网络的结构特征、传播层次及路径,探究关键节点的情感影响力和传播路径上的情感变化,并总结出网民情感传播特征。研究结果表明:可预测性灾害中灾前阶段的网民情感传播最为活跃,变化也更为复杂;网民情感传播路径较长,情感倾向会受到多个传播节点直接和间接的综合影响;网民情感传播路径上转发量较大的关键节点对网民情感的影响力更为显著。  相似文献

Dialogic communication has long been viewed as vital for effective organization-public relations. Yet, it is under-theorized whether and how organizations’ disaster communication messages may embody dialogic communication principles, and how various dialogic features are associated with different public engagement outcomes on social media. Extending the Organization-Public Dialogic Communication (OPDC) framework to the context of social media-mediated disaster communication, we propose a multi-level framework to assess the dialogic capacity of Facebook messages sent by disaster management organizations during a natural disaster. Three levels of dialogic communication characteristics (i.e., message structure-level, topic-level, and linguistic level) are examined using content analysis and Linguistic Inquiry and Word Count (LIWC). Results identified media richness, correcting, and confirming topics as three consistent predictors of public engagement of all types. Meanwhile, there exhibit greater variations regarding how other topical features and linguistic characteristics are related to public’s cognitive, emotional, and behavioral engagement during a disaster.  相似文献

在风险社会中,既存在着普遍性风险,也存在着特殊性风险,考察特殊性风险的形成与分配应从微观层面入手。文章从风险社会学的角度研究L市边缘地带H社区的地质灾害风险。在梳理技术资料获取地质灾害风险形成的自然致灾因素之后,运用口头访谈方式直接从被访问者处获得一手资料,了解其个人生活史、进入社区的不同原因与方式、居住条件、生计方式等内容,探求直接或间接的影响该区域地质灾害风险形成的社会因素,最终得出该风险的分配原则:社会地位直接决定其风险地位。  相似文献

This essay examines the relationship between transnational non-governmental organizations (NGOs) and postcolonial disasters as represented in literature. After the 1990s expansion of humanitarian organizations, a wide array of NGO-related literature emerges, including depictions of aid workers in fiction as well as humanitarian-authored narratives. While these texts contain a capacity for self-critique typically lacking in transnational NGO campaign materials, they remain mired in a ‘bureaucratic imagination’, sequestered from supposed beneficiaries. Alongside this literary development is an increasing pressure on postcolonial fiction to align with narrowly defined NGO missions, or what might be called an ‘NGO-ization of postcolonial narrative’. This essay interprets Indra Sinha’s Animal’s People as a vociferous refutation of such humanitarian pressure. Sinha stages the interaction between subaltern survivor and humanitarian benefactor not in terms of heroic salvation or radical rejection but as a conditional and negotiated solidarity. Disaster thus creates an opportunity to reimagine the subaltern-humanitarian relationship.  相似文献
