Industrial enterprises are major sources of contaminants, making their regulation vital for sustainable development. Tracking contaminant generation at the firm-level is challenging due to enterprise heterogeneity and the lack of a universal estimation method. This study addresses the issue by focusing on hazardous waste (HW), which is difficult to monitor automatically. We developed a data-driven methodology to predict HW generation using wastewater big data which is grounded in the availability of this data with widespread application of automatic sensors and the logical assumption that a correlation exists between wastewater and HW generation. We created a generic framework that used representative variables from diverse sectors, exploited a data-balance algorithm to address long-tail data distribution, and incorporated causal discovery to screen features and improve computation efficiency. Our method was tested on 1024 enterprises across 10 sectors in Jiangsu, China, demonstrating high fidelity (R² = 0.87) in predicting HW generation with 4,260,593 daily wastewater data. AI-based data-driven methods can simulate the relationship between wastewater and hazardous waste generation, enabling source estimation of hazardous waste from diverse enterprises in a uniform and lightweight manner in China.

Urban landscape forms can be effective in reducing increasing PM2.5 concentrations due to urbanization in China, making it crucially important to accurately quantify the spatiotemporal impact of urban landscape forms on PM2.5 variations. Three landscape indices and six control variables were selected to assess these impacts in 362 Chinese cities during different time scales from 2001 to 2020, using a spatiotemporal geographically weighted regression model, random forest models and partial dependence plots. The results show that there are spatiotemporal differences in the impacts of landscape indices on PM2.5. the proportion of urban green infrastructure (PLAND-UGI) and the fractal dimension of urban green infrastructure (FRACT-UGI) exacerbate PM2.5 concentrations in the northwest, the proportion of impervious surfaces (PLAND-Impervious) mitigates air pollution in northwest and southwest China, and shannon's diversity index (SHDI) has seasonal differences in the northwest. PLAND-UGI is the landscape index with the largest contribution (30%) and interpretable range. The relationship between FRACT and PM2.5 was more complex than for other landscape indices. The results of this study contribute to a deeper understanding of the spatial and temporal differences in the impact of urban landscape patterns on PM2.5, contributing to clean urban development and sustainable development.

The separation of rural families in China has resulted in a large number of "left-behind" children, who are frequently subjected to sexual abuse. Failing and insufficient tutelage owing to the migration of parents into cities and the distinctive rural living environment (e.g. drab and enclosed habitats) are the major causes of the high incidence of sexual abuse against left-behind children. We have applied the concept of "ritualized law" (lihua de fa) to delineate the powerless position of the state legal system vis-á-vis the sexual assaults committed against left-behind children in rural China. Pervasive and ingrained traditional customs and rituals, and the intermediary relationships between familiar people, have restricted the reach of the judicial system in rural areas. Moreover, deeply rooted traditional beliefs and the primacy of interpersonal (and inter-familiar) harmony over legal and formal institutions have weakened the legal system and, in many cases, allowed sexual offenders to avoid prosecution.

Seeking utilization of allied health services (AHS) has significant implications for psychological distress self-management. However, utilization of AHS by Chinese female migrant workers (FMWs) has not received enough attention. This study, therefore, aims to explore what contributes to FMWs' proactiveness in utilizing AHS. A cross-sectional study was conducted to collect data in terms of socio-demographic characteristics, work-related characteristics and AHS accessibility. A logistic regression model was adopted to examine association of these predictors with proactiveness in seeking AHS. 992 FMWs with psychological distress were interviewed with stratified multiple-stage sampling. The results indicated that Basic Public Health Services (BPHS) is a salient predictor affecting proactiveness in seeking AHS. BPHS includes psychological counseling (Odds Ratio (OR) =2.401, 95% Confidence Interval (CI) =1.284–4.490, p = 0.006), psychotherapy (OR = 2.063, 95% CI = 1.438–2.960, p = 0.000) and health knowledge lectures (OR = 1.613, 95% CI = 1.115–2.333, p = 0.011). Moreover, sampled participants under 25 and those who received education for more than 9 years are more likely to seek AHS compared with other groups. In addition, proactiveness in seeking AHS is clearly associated with working hours per day. The probability is only 31.1% for those working more than 12 h per day to seek AHS actively compared with those working below 8 h (95% CI = 0.119–0.812, p = 0.017). There are no differences between those with 8–12 working hours and those working less than 8 h (OR = 1.100, 95% CI = 0.798–1.518, p = 0.560). The present findings suggest that policies be made to improve the coverage of BPHS and to provide specified AHS to meet the increasing demand of different social groups. [ABSTRACT FROM AUTHOR]

Urbanization can induce environmental changes such as the urban heat island effect, which in turn influence the terrestrial ecosystem. However, the effect of urbanization on the phenology of subtropical vegetation remains relatively unexplored. This study analyzed the changing trend of vegetation photosynthetic phenology in Dongting Lake basin, China, and its response to urbanization using nighttime light and chlorophyll fluorescence datasets. Our results indicated the start of the growing season (SOS) of vegetation in the study area was significantly advanced by 0.70 days per year, whereas the end of the growing season (EOS) was delayed by 0.24 days per year during 2000–2017. We found that urbanization promoted the SOS advance and EOS delay. With increasing urbanization intensity, the sensitivity of SOS to urbanization firstly increased then decreased, while the sensitivity of EOS to urbanization decreased with urbanization intensity. The climate sensitivity of vegetation phenology varied with urbanization intensity; urbanization induced an earlier SOS by increasing preseason minimum temperatures and a later EOS by increasing preseason precipitation. These findings improve our understanding of the vegetation phenology response to urbanization in subtropical regions and highlight the need to integrate human activities into future vegetation phenology models.

Comparing with the effect of the average climate change on vegetation phenology, the impacts of extreme climate events remain unclear, especially considering their characteristic cumulative and time-lag effects. Using solar-induced chlorophyll fluorescence (SIF) satellite records, we investigated the cumulative and time-lag effects of drought and heat events on photosynthesis, particularly for the end date of autumn photosynthesis (EOP), in subtropical vegetation in China. Our results showed a negative effect of drought on the delay of EOP, with the cumulative effect on 30.12% (maximum continuous dry days, CDD), 34.82% (dry days, DRD), and 26.14% (dry period, DSDI) of the study area and the general time-lag effect on 50.73% (maximum continuous dry days), 56.61% (dry days), and 47.55% (dry period) of the study area. The cumulative and lagged time were 1–3 months and 2–3 months, respectively. In contrast, the cumulative effect of heat on EOP was observed in 16.27% (warm nights, TN90P), 23.66% (moderate heat days, TX50P), and 19.19% (heavy heat days, TX90P) of the study area, with cumulative time of 1–3 months. The lagged time was 3–4 months, detected in 31.02% (warm nights), 45.86% (moderate heat days), and 36.52% (heavy heat days) of the study area. At the vegetation community level, drought and heat had relatively rapid impacts on EOP in the deciduous broadleaved forest, whereas evergreen forests and bushes responded to heat slowly and took a longer time. Our results revealed that drought and heat have short-term cumulative and time-lag effects on the EOP of subtropical vegetation in China, with varying effects among different vegetation types. These findings provide new insights into the effect of drought and heat on subtropical vegetation and confirm the need to consider these effects in the development of prediction models of autumn phenology for subtropical vegetation. • The effect of extreme climate on EOP of subtropical vegetation in China were analyzed. • Drought and heat had short-term cumulative and time-lag effects on the EOP. • Drought and heat had rapid impacts on EOP in the deciduous broadleaved forest. • Evergreen forests and bushes responded to heat slowly.

Background: Although there is a wealth of evidence indicating the enduring consequences of childhood emotional maltreatment (CEM) on social and relational functioning across life stages, little known about how CEM affects marital attitudes in emerging adulthood, particularly among rural first-generation college students (rural FGCS) at the critical stage of developing romantic relationships., Objective: To explore whether differential patterns of CEM existed among rural FGCS in China during emerging adulthood. Furthermore, the study aims to examine the potential differences in the chain mediating role of CEM on the pathway to adulthood marital attitudes across different CEM profiles., Participants and Setting: Using a cluster sampling approach, a total of 3848 rural first-generation college freshmen (males = 39.2 %, mean age = 18.42 years) were recruited from three universities in China., Methods: Latent profile analysis was utilized to identify potential patterns of CEM using Mplus version 7.4. Structural equation modeling and multigroup comparisons were then performed to investigate the association between CEM and attitudes towards marriage in emerging adulthood, utilizing AMOS 24.0., Results: Three profiles of CEM was identified among rural FGCS: a low-CEM group (51.87 %), a moderate-CEM group (36.69 %), and a severe-CEM group (11.44 %). The association between CEM and adulthood marital attitudes was mediated by core self-evaluation and meaning in life. However, the mediation effects varied across the three CEM profiles. In the low-CEM group, core self-evaluation and meaning in life were observed to partially mediate the negative association between CEM and adulthood marital attitudes. On the other hand, in the moderate-CEM and severe-CEM groups, the relationship between CEM and adulthood marital attitudes was fully mediated by core self-evaluation., Conclusions: The study's findings suggest that CEM is a significant predictor of marital attitudes among rural FGCS during emerging adulthood, with the severity of emotional neglect and abuse being the primary distinguishing factor between different CEM profiles. Core self-evaluation plays an important role in this relationship. Future clinical interventions could benefit from focusing on enhancing core self-evaluation and meaning in life, particularly for those with CEM experiences., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Ltd.

Background: Older migrant workers (OMWs) in China face unique challenges rooted in their early life experiences, which increase their vulnerability to psychological and behavioral problems in adulthood. By utilizing the cumulative disadvantage model and the social-ecological systems theory, this study explored the effect of childhood family adversity on adulthood depression in the mediating roles of OMWs' social-ecological microsystem and mesosystem and further examined gender differences in these associations., Methods: Data were collected from the China Health and Retirement Longitudinal Study (CHARLS), involving a sample of 4,309 OMWs aged 50 and above. The measures included the Center for Epidemiological Research Depression Scale, childhood family adversity, socioeconomic status, marital quality, and physical and cognitive health., Results: Childhood family adversity was positively associated with adulthood depression among OMWs. Social microsystem (physical and cognitive health) and mesosystem (marital quality and socioeconomic status) factors significantly mediated this relationship. Multi-group analysis revealed that the mediating effects of marital quality and socioeconomic status were stronger for female OMWs, while the mediating effects of physical and cognitive health were stronger for male OMWs., Conclusions: The findings suggest that childhood family adversity has a lasting impact on the mental health of OMWs, and that social-ecological systems factors play an important role in this relationship. The study also highlights the need for gender-specific interventions to address the mental health needs of OMWs., (© 2024. The Author(s).)

Background: Rural-to-urban migrant workers are a vulnerable group at risk of developing depression. Based on the social-ecological systems theory, this study investigates the impact of the lack of social integration on depression, considering the mediating roles of migrant workers' microsystems (family happiness and job burnout). Additionally, the study explores whether having sons influences these associations., Methods: The sample of 4,618 rural-to-urban migrant workers was obtained from the 2018 wave of the China Labor Force Dynamics Survey (CLDS). All the measures in the survey exhibited good reliability, including the Center for Epidemiological Research Depression Scale (CES-D), family happiness, job burnout, and social integration. The data were primarily analyzed using a structural equation model., Results: Social integration had a direct impact on depression among migrant workers. Additionally, it indirectly affected depression through the mediating roles of family happiness not job burnout. The moderating effect of having sons mainly occurred on the path from social integration to family happiness., Limitations: The cross-sectional design impeded the ability to draw causal inferences., Conclusion: This finding highlights the potential benefits of social integration and family happiness in promoting early prevention of depression among migrant workers. It indicates that the inclination toward having sons among migrant workers continues to impact their mental health., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Shen, Tang, Fang, Huang, Zheng, Wu, Yang, Chen and Chen.)

To maintain the health of aquaculture fish, it is critical to understand the composition of microorganisms in aquaculture water and sediment and the factors affecting them. This study examined the water and sediment microbiota compositions of four different types of ponds in South China that were used to culture grass carp ( Ctenopharyngodon idella ) of different sizes through high-throughput sequencing of the 16S rRNA gene, and analyzed their correlations with environmental factors. The results showed that ponds with cultured grass carp of different sizes exhibited significant differences in terms of water physicochemical properties and composition of water and sediment microbiota. Furthermore, the exchange of microorganisms between water and sediment microbiota was lowest in ponds with the smallest grass carp and highest in ponds with the largest grass carp. All detected environmental factors except water temperature were significantly correlated with the water microbiota, and all detected environmental factors in the sediment were correlated with sediment microbiota. Moreover, Aeromonas hydrophila and Vibrio were significantly increased in the water microbiota, especially in ponds with small juvenile grass carp, implying an increased risk of A. hydrophila and Vibrio infections in these environments. Our results provide useful information for the management of grass carp aquaculture ponds., Competing Interests: Yingli Lian, Jian Wang, Jiayi Tang, Xuan Zhu and Baojun Shi are employed by Guangdong Haid Group Co., Ltd. Sampling was conducted at a site associated with Guangzhou Chengyi Aquatic Technology Co., Ltd., China, which is partner to one of our affiliations., (©2023 Lian et al.)

Based on a survey of 2343 rural residents in China, this paper adopts a binary logistic regression model as the analytical tool to study the impact of rural residents' social network and sense of responsibility regarding their participation in environmental governance. The results show that the cost, frequency and scope of social network activities have positive and significant influences on resident participation in rural environmental governance. The cost of a social network is conducive to building a rural social network, enhancing the connection of interests and promoting the formation of a rural community. Extending social network objectives from family members to villagers can improve the cultural identity and emotional identity of rural residents. The increase in the frequency of social network activities can not only enhance trust among residents, but also reduce the cost of environmental governance mobilization. The scope of a social network acts as an inhibitor whereby social interaction beyond the scope of rural areas will reduce identification with rural emotions. The four dimensions, including responsibility cognition, responsibility will, responsibility emotion and responsibility behavior have significant influences on resident participation in rural environmental governance. Residents' sense of responsibility plays the role of an introverted driving force for them to take part in rural environmental governance, which itself helps to overcome "non-participation" behaviors of "rational smallholders" to a certain extent. Furthermore, it endows rural environmental governance with resilience. So, it is of significance to enhance rural residents' social networks and to improve rural residents' cognition of collective responsibility.

Rural health governance is an important part of low-carbon green life, which is also related to the sustainable development and population health project in rural areas. Based on the survey data of 2343 rural residents in China, this study adopted a binary logistic regression model to explore the effects of rural residents' social network and cognition on their participation in rural health governance. The research results show that only less than 30% of the respondents participated in rural health governance, and the proportion of rural resident participating is not high. Both their social network and cognition have a significant impact on their participation in rural health governance. Introverted communication helps strengthen the connection between rural residents, form the network and structure of rural social communication, build emotional links and common interests, and form a common cultural understanding paradigm and action framework. The extraverted communication means that rural residents gradually break away from the social network of acquaintances, which is not conducive to building a rural community. Rural residents' understanding of behavior begins to deviate from rural culture, customs and emotional values, and the binding force of traditional culture is reduced, making it difficult to motivate them to participate in rural public life. Policy cognition can improve rural residents' recognition of the value and significance of health governance. Responsibility awareness is the internal driving force for rural residents to participate in health governance, which can also reduce the governance cost of rural managers. Based on this, increasing rural residents' introverted communication and cultivating their sense of responsibility are key to promoting their participation in rural health governance.

In the post-pandemic era, the need for resilient and flexible COVID-19 prevention strategies in rural areas has become increasingly prominent. Based on a sample of 2229 rural residents nationwide, the Structural Equation Model was adopted to analyze the influence of social capital and technological empowerment on pandemic resilience in rural areas. The proportion of diversity, adequacy, and effectiveness of pandemic prevention measures taken by communities was about 57%. Social capital (0.667) and technological empowerment (0.325) had a significant positive impact on rural resilience and pandemic prevention. Social capital plays a mediating role between technological empowerment and pandemic resilience in rural areas. The risk of disease in society stimulates the inherent social capital factors in villages, with the individual social network generating strong social support. Technological empowerment can not only provide new methods for the connection of social capital, but also bring new means for rural authorities to improve their governance capabilities. Social trust in social capital plays an important role in rural resilience and pandemic prevention. The indirect effect of technological empowerment through social capital on pandemic resilience is greater than its direct effect. Social capital construction is the key to rural resilience and pandemic prevention.

China's rapid urbanization can be attributed, in part, to the contribution of female migrant workers. However, they are a socially vulnerable group. In order to explore the vulnerability of female migrant workers and its reasons, questionnaires and in-depth interviews were conducted with female migrant workers in Guangdong and Hubei provinces, China, and 992 questionnaires and 147 interview data were finally collected as the research object. The descriptive statistical analysis was conducted with the quantitative data to reveal the livelihood vulnerability of female migrant workers and its reasons, and qualitative data were used to corroborate and consolidate the argument. "Ritualistic institution" is the key to understanding the livelihood fragility of female migrant workers. The policy on migrant workers has weakened the concept of family, making it difficult for families, which are on the fringes of the national policy vision, to benefit from the system. Therefore, the livelihood costs of female migrant workers have increased. Traditional gender norms also make it difficult for migrant women to enjoy the limited benefits and resources of the policy. This weakens the authoritative role of the policy in solving the problem of livelihood vulnerability for migrant workers, particularly women. This shows that China's policy on migrant workers is somewhat symbolic. Through "family separation" and "ritualistic institution", it can be seen that China's urbanization is a modern development activity that carries urban bias and lacks humanistic care value. This is bound to result in the neglect of human development, gender differences, and family, making it difficult for rural migrant women to survive. This in-depth study seeks to find solutions to the problems prevalent under the cover of contemporary Chinese modernity.

Family separation in rural China has led to a considerably large number of left-behind women who have to deal with livelihood fragility. The Department for International Development (DFID) framework focusing on households provides a base to understand the livelihood fragility of these women. Based on this framework and the existing field research, this study identifies that the national macro-strategy of unsynchronized development of industrialization, informatization, urbanization, and agricultural modernization leads to a separated migration model for rural families. Furthermore, the process of social modernization increases the fragility risk of how the left-behind family functions. The traditional gender culture expectations also directly affect rural families to make the livelihood strategy choice of, "male working outside, female taking care of home". Based on the above theoretical research, this study extracts the concept of "ritualized law" to shed light on gender differentiation and family separation. A number of formal social security institutions have been established to promote the development of farmers, however, the ingrained culture gender differentiation encourages men to work in the profitable urban industry while women work in the field of unpaid agriculture and shoulder the responsibility of housework. This makes the formal institution a symbolic ornament for left-behind women, while they are forced to stay in rural areas and suffer from the fragility of livelihood.
