In public health emergencies, people are more willing to save money rather than spending it, which is not conductive to economic development and recovery. Due to the absence of relevant research, the internal logic of this phenomenon is not clear. In the context of the COVID-19 pandemic, this study systematically explored whether and why public health emergencies stimulate consumers' preference for saving. We conducted two online surveys and used methods including stepwise regression analysis and bootstrapping to test the hypotheses. The (...) first survey, with 1,511 participants from China in February 2020, indicates that the severity of emergencies has a significant positive impact on the populations' willingness to save. Risk perception plays a mediating role between the severity of emergencies and consumers' saving willingness. Materialism plays a moderating role between risk perception and an individual's saving willingness, individuals who are more materialistic have a lower saving willingness when they perceive the risks of the pandemic. To verify the duration of the above effects, we conducted a follow-up survey consisted of 466 instances in August 2020. It is noteworthy that the above effects are not significant during the post-pandemic period. Thus, spending behavior in public health emergencies can be motived by reducing risk perception and increasing materialism. These findings can provide a valuable inspiration for public health, crisis management, and economic recovery during public health emergencies. (shrink)

Environmentality teases out the multilayered human-environment contacts and connections in terms of human agency and governmentality, ecological objects and their (in)dependence, power/knowledge and environmental (in)justice. “Sustainable Development Goals” recognize that ending poverty and other deprivations must go hand-in-hand with strategies that improve health and education, reduce inequality, and spur economic growth – all while tackling climate change and working to preserve our environment. This paper outlines the scopes, scales, and methods of Chinese storytelling and multimedia exhibitions on deforestation and afforestation, (...) pollution and purification, and wastelands and eco-systems in industrial, de-industrial, and post-industrial times. The author considers short stories, novellas, novels, reportages, nonfiction writings, and visual artworks, with specific focus on trees, forests, and plant writing. By reading Kong Jiesheng’s “Forest Primeval,” Ah Cheng’s “King of Trees,” Xu Gang’s Loggers, Wake Up!, Yan Lianke’s Garden No. 711: The Ultimate Last Memo of Beijing, and Chen Yingsong’s The Forest Is Silent, the author aims to bring to light the awakening and formation of Chinese ecological consciousness, the token of marred humanity and ecocritical reflection, the manifestation of biophilia-biophobia experiences, as well as the structural transformation of private feelings and public emotions in modern and contemporary China.

The pattern, process, and mechanism of residential heterogeneity vary significantly with different geographical scales. However, most traditional methods ignore the checkboard and modifiable areal unit problem, which may cover up the complexity and hierarchy of social space. Taking Hangzhou city as an example, a multiscalar method was proposed based on the information entropy theory to estimate residential heterogeneity and its scale sensitivity. Based on the sixth population census of Hangzhou and the housing price database of 6,536 residential districts from 2008 (...) to 2018, we explore the scale effect and dynamic characteristics of residential heterogeneity. The results of spatial simulation and geostatistical analysis based on Python Spatial Analysis Library module show that the multiscalar algorithm better presents the real segregation pattern than traditional method, which is one of the new models and technologies in urban geography complex system. Exploring residential heterogeneity through multiscalar lens provides an important basis for the gradual and refined urban renewal. (shrink)

In this paper, we present a probabilistic-based method to predict malaria disease at an early stage. Malaria is a very dangerous disease that creates a lot of health problems. Therefore, there is a need for a system that helps us to recognize this disease at early stages through the visual symptoms and from the environmental data. In this paper, we proposed a Bayesian network model to predict the occurrences of malaria disease. The proposed BN model is built on different attributes (...) of the patient’s symptoms and environmental data which are divided into training and testing parts. Our proposed BN model when evaluated on the collected dataset found promising results with an accuracy of 81%. One the other hand, F1 score is also a good evaluation of these probabilistic models because there is a huge variation in class data. The complexity of these models is very high due to the increase of parent nodes in the given influence diagram, and the conditional probability table also becomes more complex. (shrink)

The Transforming growth factor beta (TGF‐β) family of secreted proteins regulates a variety of key events in normal development and physiology. In mammals, this family, represented by 33 ligands, including TGF‐β, activins, nodal, bone morphogenetic proteins (BMPs), and growth and differentiation factors (GDFs), regulate biological processes as diverse as cell proliferation, differentiation, apoptosis, metabolism, homeostasis, immune response, wound repair, and endocrine functions. In Drosophila, only 7 members of this family are present, with 4 TGF‐β/BMP and 3 TGF‐β/activin ligands. Studies in (...) the fly have illustrated the role of TGF‐β/BMP ligands during embryogenesis and organ patterning, while the TGF‐β/activin ligands have been implicated in the control of wing growth and neuronal functions. In this review, we focus on the emerging roles of Drosophila TGF‐β/activins in inter‐organ communication via long‐distance regulation, especially in systemic lipid and carbohydrate homeostasis, and discuss findings relevant to metabolic diseases in humans. -/- .

This study explored how perceived control affects consumers' willingness to purchase self-improvement products under self-deficit situations. For this purpose, three experiments were conducted to examine the following sources of control: the controllability of self-deficits ; the locus of control ; and situational perceived control. According to the results, higher perceived control can reduce consumers' defensive reaction tendencies, thus increasing their willingness to purchase products that claim to improve their current deficits. Moreover, the aforementioned effect only occurs in within-domain improvement products, (...) rather than without-domain improvement products. (shrink)

Ritualistic consumption refers to integrating ritual elements into the process of product design and usage. By conducting three studies, we find that ritualistic consumption can offer new and interesting experiences and help consumers gain a sense of control. Both positive and negative emotions can promote ritualistic consumption tendencies. However, their underlying psychological mechanisms are different. Specifically, positive emotion can arouse consumers’ desire for interesting experience and thus promotes their preference for ritualistic consumption, while negative emotion can arouse consumers’ need for (...) control and thus promote their preference for ritualistic consumption. Our research results offer a theoretical contribution and practical inspiration for emotional marketing. (shrink)

This paper examines Chinese imagery of smokestacks both as a concrete object and an abstract concept emerging from early futurist eulogy to modernist allergy, and from Maoist propaganda to post-Fifth Generation environmental reflections. In the Republican era, writers from the Creation Society eulogize the smokes of steamboat smokestacks as beautified symbols of modern civilization. Yet members from the Beijing School convey their concerns about the Janus face of industrialization and environmental impairments. After 1949, smokestacks are eulogized as an icon of (...) socialist industrialization and pervade cinematic productions, literary imaginations, and artistic exhibitions. Since the 1980s, smokestacks have been gradually understood as vestiges of problematic socialist practice. The growing ecological deterioration in the 21st century propels public intellectuals and film directors to expose industrial pollution and to invoke environmental protection. Yet another type of representation arises in the post-Fifth Generation films, where smokestacks are visualized as a token of the “insulted and injured” working class, individual discovery, and collective sentiment worn out by the post Mao-Deng global developmentalism and social injustice. The metamorphoses of smokestacks in literary, cinematic, and artistic imaginations envision and exhibit the structural transformation of modern Chinese environmental and ecological consciousness.
