Profanity, also known as swearing, refers to the use of foul language that is often linked to incivility. In Chinese digital space, the state government actively censors profanity under the rationale of protecting online civility. This study examines the diffusion of profanity in Sina Weibo, one of the largest Chinese social media platforms. The study applied computational methods to reconstruct the cascade networks of swearing and non-swearing posts and analyzed the network diffusion processes based on a set of structural metrics including reposting depth, width, and interlayer width ratios. Findings suggest profanity may influence the process of message diffusion, but this effect was ephemeral. Based on the understanding of diffusion processes of profanity online, this study contends the viral potential of profanity may not be as severe as the regulators claim. The discussion analyzes the extent to which content moderation efforts are necessary for the nurturing of civility online.

BACKGROUND: Although good progress was made in maternal and child nutrition during the Millennium Development Goals (MDGs) era, malnutrition remains one of the major threats on global health. Therefore, the United Nation set several nutrition-related goals in the Sustainable Development Goals (SDGs). There is much to be learned from individual countries in terms of efforts and actions taken to reduce malnutrition. China, as a developing country, launched a number of nutrition improvement policies and programs that resulted in dramatic progress in improving maternal and child nutrition during the MDGs era. This study explored the impact, experiences, and lessons learned from the nutrition policies and programs initiated in China during the MDGs era and implications to achieve the SDGs for China and other developing countries. METHOD: The CNKI database and official websites of Chinese government were searched for reviews on nutrition-related policies and intervention programs. A qualitative study was conducted among key informants from the Chinese government, non-governmental organizations (NGOs), and universities for two major national nutrition intervention programs. RESULTS: The literature review documented that during the MDGs era, six nutrition policies and eight trans-province and nationwide nutrition intervention programs collectively made good progress in improving maternal and child nutrition in China. Nutrition policies tended to be targeted at infants and children, with less attention on reproductive and maternal nutrition. Nutrition intervention programs focused primarily on undernutrition and have achieved positive results, while for breastfeeding improvement and prevention and control on overweight and obesity were limited. Results from the qualitative study indicated that effective nutrition program implementation was facilitated through the cooperation of multiple sectors and by the government and NGO partnerships, however, still face challenges of insufficient operational funds from local ...

The high temperature gas-cooled reactor (HTGR) has potential utilization due to its featured characteristics such as inherent safety and wide diversity of utilization. One distinct difference between HTGR and traditional pressurized water reactor (PWR) is the large inventory of graphite in the core acting as reflector, moderator, or structure materials. Some radionuclides will be generated in graphite during the period of irradiation, which play significant roles in reactor safety, environmental release, waste disposal, and so forth. Based on the actual operation of the 10 MW pebble bed high temperature gas-cooled reactor (HTR-10) in Tsinghua University, China, an experimental study on source term analysis of the irradiated graphite has been done. An irradiated graphite sphere was randomly collected from the core of HTR-10 as sample in this study. This paper focuses on the analytical procedure and the establishment of the analytical methodology, including the sample collection, graphite sample preparation, and analytical parameters. The results reveal that the Co-60, Cs-137, Eu-152, and Eu-154 are the major γ contributors, while H-3 and C-14 are the dominating β emitting nuclides in postirradiation graphite material of HTR-10. The distribution profiles of the above four nuclides are also presented.

The trade dispute between China and the United States (US) since 2018 and the global COVID-19 pandemic since 2020 has significantly impacted China's economic development. As China's energy sources heavily depend on imports, its economic viability is becoming more and more risky. This study proposes a novel conceptual framework, involving macroeconomic, industrial and geopolitical factors, to evaluate China's energy security as a major player in the trade dispute. This study also provides a comprehensive strategy for policymakers to make better decisions on reforming renewable energy patterns to guarantee energy security and achieve geopolitical advantages. The PESTEL (political, economic, social, technical, environmental and legislative) and SWOT (strengths, weaknesses, opportunities and threats) analytical methods are applied to evaluate the factors and attributes of China's energy development and energy security in the current background. The China-US bipartite game reciprocity model and the QSPM (Quantitative Strategic Planning Matrix) analysis are conducted to assess which energy security strategy and policy are more suitable to deal with China-US trade dispute. To enhance energy security, China should diversify its energy supply chain, develop new sources of energy supply, advance the shale gas technology, popularise cleaner power-generation plants, increase nuclear-energy safety, introduce energy-conservation measures, promote alternative-energy vehicles, engage in international energy diplomacy, and rebuild international energy transaction and settlement systems.

Background: The objectives of the current study were to identify the trends in child nutrition, the gaps in achieving child nutrition-related goals, and implications for program and policy options for the Chinese government. Methods: Eight child nutrition-related indicators from the Sustainable Development Goals (SDGs) and China's national nutrition plans, and two datasets, Global Burden of Disease 2016 and Chinese National Nutrition and Health Surveillance, were used in our analysis. Results: Over the past 26 years, the prevalence of stunting, wasting, and underweight for children under 5 years was reduced by 58.7%, 53.4%, and 69.2%, respectively. Overweight for children aged 1–4 years increased 88.9% and obesity increased 2.14 times. Exclusive breastfeeding of newborns (7–28 days) was stable, at about 30%. We estimated child wasting would be 3.0% lower than the target of 5.0% based on predictive values for meeting the SDGs in 2025. The number of stunted children under five years would be reduced by 39.7%, while overweight would increase 2.2% throughout China. Conclusion: These results highlight the urgent need for targeted policies and interventions to reduce child stunting and overweight and increase exclusive breastfeeding to improve child health and meet the SDG targets and China's national goals.
