At the end of 2019, during the outbreak of COVID-19, the Chinese government and media used social media extensively to release emergency information. Once this information was released, it immediately attracted significant public attention. This study used a questionnaire survey to determine social media users’ habits during the COVID-19 outbreak. The results indicated that in the case of community closure during sudden public health events, the majority of respondents use social media to obtain information to understand the development trends of an epidemic, the government’s emergency strategy, scientific epidemic prevention knowledge, and accurate information. Based on the survey results, this study considers the value of social media for emergency information, which is both a tool and a new trend in information dissemination in the context of emergencies.
The widespread application of social media in the field of crisis management has been adopted globally. In recent years, the role of social media in emergencies has grown, especially during the coronavirus disease 2019 (COVID-19) pandemic. This study explores the different roles played by social media in the government, the media, and the public during the pandemic through the key nodes of information dissemination at each developmental stage of crisis risk communication. The results indicate that in a government-led environment, in which social media is the link and the public is the core, attention must be directed towards the key role of social media as a “whistleblower” during the incubation period of a crisis event. Moreover, a new gatekeeping mechanism that integrates the public, the media, and the government should be formed to improve emergency management during crises.
The focus of this study is to assess regional ecological security, based on a method of combining the ecological sensitivity evaluation and the ecosystem services evaluation of Tongling City, China. This approach may reduce the possible errors caused by basing the assessment on only one of these two evaluation methods. The PCA (Principal Component Analysis) and rectified ESV (Ecosystem Services Value) methods were employed in this study with the support of SPSS, RS and ARCGIS. The study showed the following results: the ecological sensitive area is mainly located among the wetland concentrated areas along the river in the north and the forested and green spaces within and around the city, and the area with the highest value is the mountainous areas in the south; the northern wetland area along the river and the southern forested mountain area have high ecosystem services value. Finally, the study identified the ecologically fragile and important services areas, and offered a reliable reference for Tongling's ecological protection and urban growth decisions by dividing the ecological security evaluation areas into areas with low, mid and high ecological security levels.
Purpose. The commercial life of cut flower varieties was generally considered to be as short as fashion. However, this study provides an example of a perennially popular cut flower variety that offers an alternative perspective on the potential of the cut flower market.
Methods. Semi-structured interview and qualitative document analysis.
Results. This article presents an analysis of the evolution of the cultivation and sale of a popular cut flower species over time. It also discusses the impact of a trading company on various stakeholders in the supply chain, as well as relevant business and legal considerations.
Conclusions. This article highlights the importance of effective management of the Notification Letter, related agreements and intellectual property rights, taking into account the potential legal and business implications arising from the relevant transactions and statute of limitations. In addition, the article provides valuable insights for breeders and stakeholders seeking to establish identities for new plant varieties in markets, highlighting the importance of understanding the supply chain and implementing appropriate intellectual property strategies and portfolios, such as trademarks and plant variety rights, to facilitate business success.
This paper studies rural land value appreciation and the wealth redistribution effects of China's dual land system, taking Beijing as a case study. We propose a robust method to estimate the land value gap between the land granting price paid by the developer and the rural resident's compensation for the expropriated land. The study shows that the land value gap manifests dramatic variability. While, on average, expropriation charges amount to 15 per cent of the estimated market value of land, this share is under 5 per cent in about a quarter of all rural expropriation cases. The land value gap shows significant and positive correlation with market prices and the intended use for the land, and significant evidence of spatial dependence and heterogeneity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
