Phoenix Man, An Example of Stigmatization Phenomenon in the China Social Media
No full textWith the rapid transformation and development of contemporary Chinese network society, the phenomenon of stigmatization is becoming more and more common in social media communication. The theory about the social stratum and the mobility of society could give us a good theoretical explanation, it could help us understand why a group is stigmatized and excluded. The purpose of this article was to find out the formation mechanism of stigmatization with Phoenix man through literature review and qualitative analysis, linked this phenomenon to social mobility and anxiety of middle-class in China, and finally point out the existing deep-seated social inequality problems and hazards in China. Through the network search engine "Baidu" and literature review, get the network search index and some other social media information about Phoenix Man, found the process (initial, development and final) of stigmatization phenomenon of Phoenix Man, and made reasonable analysis. By compared Phoenix Man with the two groups, Zhuanjia and Gongzhi, it easily to find that Phoenix Man have always been highly concerned in Chinese social media. Finally, this study found that the stigmatization was originated from the anxiety caused by differences in cultural, customs and habits between middle-class and the lower-class. The stigmatization made the people who came from lower class groups been marginalized, also damaged social justice and harmony
Rediscovering climate gerontology: an era for older adults to contribute more to climate change
No full textIn the wake of escalating climate challenges, the role of diverse specific groups in climate action has gained unprecedented attention. Among these groups, older adults, often overlooked, present a unique potential in the realm of climate action. The concept of climate gerontology, first introduced by Haq and Gutman in 2014, encapsulates this intersection of gerontology and climate change. However, despite its initial proposal, the field has not fully developed its potential. This article aims to revisit and expand the concept of climate gerontology, arguing for a more active and recognized contribution of older people in climate-change initiatives
Prediction of the Old-Age Dependency Ratio in Chinese Cities Using DMSP/OLS Nighttime Light Data
No full textThe old-age dependency ratio (ODR) is an important indicator reflecting the degree of a regional population’s aging. In the context of aging, this study provides a timely and effective method for predicting the ODR in Chinese cities. Using the provincial ODR from the Seventh National Population Census and Defense Meteorological Satellite Program/Operational Linescan System (DMSP/OLS) nighttime light data, this study aims to predict and analyze the spatial correlation of the municipal ODR in Chinese cities. First, the prediction model of the ODR was established with curve regression. Second, the spatial structure of the municipal ODR was investigated using the Moran’s I method. The experimental results show the following: (1) the correlation between the sum of the nighttime light and ODR is greater than the mean of nighttime light in the study areas; (2) the Sigmoid model fits better than other regression models using the provincial ODR in the past ten years; and (3) there exists an obvious spatial agglomeration and dependence on the municipal ODR. The findings indicate that it is reasonable to use nighttime light data to predict the municipal ODR in large and medium-sized cities. Our approach can provide support for future regional censuses and spatial simulations

No full textInfluenced Zone of Deep Excavation and a Simplified Prediction Method for Adjacent Tunnel Displacement in Thick Soft Soil
No full textBased on the statistics of 42 case histories, 732 finite element numerical simulations are conducted to determine the scope of the influenced zone of deep excavation under different conditions of excavation depth (He) and the maximum retaining wall deflection (δhm). On this basis, the effects of He and δhm on the scope of the influenced zone are studied, and a simplified prediction method for the scope of the influenced zone under any He and δhm conditions and the adjacent tunnel displacement is proposed. Then, the reliability of the proposed method is verified by comparing it with the current research and case histories. And finally, the proposed method is applied to an actual project, and the application effect is evaluated. The results show that the range outside the pit can be divided into “primary”, “secondary”, “general”, and “weak” influenced zones. The influenced zone can be simplified as a right-angled trapezoid shape, and the scope of influence zones can be quickly determined by defining three parameters: width coefficient M, depth coefficients N1 and N2. The parameters M and N2 have a linear relationship with He and δhm, and N1 varies between 1–2 with an average of about 1.5. In actual application, the effect of deep excavation on the adjacent tunnel can be alleviated by using the proposed method to predict the excavation-induced displacement of the adjacent tunnel and take some measures
