Exploring the urban consumers’ experience and the influencing factors in berry-picking activities in China

ABSTRACT Berries hold a unique appeal, stemming from their natural aspect and the embedded cultural ecosystem services they can offer. While extensive studies have examined rural berry collectors, there is a gap of research on the engagement of urban consumers in berry-picking activities, particularly in emerging markets. This study addresses this gap by investigating the experience, consumer motivations, and other influential factors of urban consumers engaging in berry-picking activities in selected municipalities in China. Drawing on in-depth interviews with urban consumers involved in berry-picking and the thematic analysis, this research revealed three berry-picking patterns, including wild picking, pure commercial picking (U-pick), commercial picking with extra services (Pick and Plus). It identified key factors influencing urban consumer experience, namely consumer motivations, social media marketing, convenience, and service capability. It explored the challenges confronting individual berry farmers. The results highlighted the cultural and social significance of berry-picking activities, as well as the service potential of fresh berries as territorial products to bridge urban-rural divides. The research contributes up-to-date insights to the broader discourse on the cultural and provisioning ecosystem services offered by berries, shedding light on the intricate interplay among urban consumers, fresh berries, rural berry farmers and other relevant stakeholders.

Peroxyacetyl nitrate can be used as a comprehensive indicator of air pollution complex

With the acceleration of air cleaning activities in China, air pollution has entered a new stage characterized by seasonal interplay and predominance of fine particulate matter (PM2.5) and ozone (O3) pollutants. However, the differing peak seasons of these two pollution preclude the use of a unified indicator for air pollution complex. Given that peroxyacetyl nitrate (PAN) originates from secondary formation and persists under low-temperature conditions for extended periods, it is vital to determine whether its concentration can be used as an indicator to represent air pollution, not only in summer but also in winter. Here, PAN observational data from 2018 to 2022 for Beijing were analyzed. The results showed that during photochemical pollution events in summer, secondary formation of PAN was intense and highly correlated with O3 (R = 0.8), while during PM2.5 pollution events in winter, when the lifetime of PAN is extended due to the low temperature, the PAN concentration was highly consistent with the PM2.5 concentration (R = 0.9). As a result, the PAN concentration essentially exhibited consistency with both the seasonal trends in the exceedance of air pollution (R = 0.6) and the air quality index (R = 0.8). When the daily average concentration exceeds 0.5 and 0.9 ppb, the PAN concentration can be used as a complementary indicator of the occurrence of primary and secondary standard pollution, respectively. This study demonstrated the unique role of PAN as an indicator of air pollution complex, highlighting the comprehensive ability for air quality characterization and reducing the burden of atmospheric environment management.

New outlets of digital feminist activism in China: the #SeeFemaleWorkers campaign

ABSTRACT This article examines the #SeeFemaleWorkers campaign in China, which has been one of the most influential digital feminist movements in recent years despite the patriarchal and repressive political environment in the country. The campaign not only achieved its initial goal of raising the media visibility of female health workers fighting the pandemic, but also drew public attention to the unseen contributions of female workers in all walks of life. By analysing the narrative themes and frequency of the randomly selected original posts, this study identified thematic categories to conceptualise themes of participation. Subsequently, we suggest that the intersectional nature of the campaign was an important factor in its success as it enabled women from different backgrounds to come together and discuss discrimination in the workplace. We also found that the campaign managed to evade misogynistic antagonism by avoiding polarising labels. Finally, we suggest that the reuse of socially established hashtags can be beneficial for conducting follow-up activities and sustaining the influence of the original campaign. However, the study also highlights the potential risks posed by censorship and surveillance in China, which can hinder the development and success of digital feminist activism.

2020–2022年环渤海地区8 m分辨率露天采矿区空间分布数据集

With the increase of mining activities in China, the ecological environment around mines is facing unprecedented pressure, leading to a series of resource, ecological and environmental problems, such as air pollution, soil erosion, solid waste pollution, landslides and debris flows. To precisely obtain the spatial distribution data of open-pit mining, scholars and regulatory bodies are actively seeking timely and efficient methods to monitor open-pit mining areas by using the remote sensing, an innovative technology, for this purpose. In this research, we adopted high-resolution optical remote sensing image GF-6 with a resolution of 8m to obtain the open-pit mining dataset in the Bohai Rim through rule-based feature extraction, time-series image discrimination and visual interpretation methods, covering over 8000 open-pit mining areas. The dataset exhibits a high level of accuracy, with an overall accuracy of 95.0%, a producer accuracy of 98.0% and a user accuracy of 92.4%. It effectively reflects the spatial dynamics in the distribution of open-pit mining areas within the Bohai Rim region and reveals the influence of economic growth and policy-making on these changes. Thus, the dataset can offer valuable data support for managing open-pit mining operations and the development of related policies.

Walking in “Masses and Elites”: Investigation into Donald MacGillivray’s Missionary Strategies in China (1888–1930)

From his arrival in China in 1888 to his departure in 1930, Canadian missionary, Donald MacGillivray (季理斐), was in China for more than 40 years. According to changes in the Chinese missionary situation, the key target of his mission was frequently adjusted. From his initial work in the early days in North Honan, to his work with officials and intellectuals in Shanghai in the late Qing Dynasty, then to students, women, and children in the Republic of China, Donald MacGillivray continued to preach to both the masses and the elites. His approach was flexible, ranging from oral preaching to academic publications. Relying on his interpersonal network, MacGillivray paid close attention to the social changes occurring in modern China. An evaluation of his activities in China can not only reveal the impact of individual missionaries in the process of Western learning and the transformation of Chinese knowledge in modern times, but also provide insight into the integration of Christianity into the indigenization process of China.

Empowering collaborative knowledge construction through the implementation of a collaborative argument map tool

Collaborative knowledge construction has been used in higher education to support student groups' collaborative learning activities through students' exchange, negotiation, and reflection of perspectives through peer communications. To support this process, collaborative learning analytics tools have been designed to collect and analyze collaborative process and performance data with a goal to provide actionable feedback and improve learning quality. However, few tools have demonstrated the mechanism and details about how students develop their perspectives during the collaborative knowledge construction process in higher education. To fill this gap, this research proposed a tool named Collaborative Argument Map (CAM) that creatively visualized different types of perspectives students proposed from the individual, peer, and group levels. This tool was further implemented in a graduate-level course in online collaborative writing activities in China's higher education, with a goal to support students' knowledge construction with peers. The summative and process-oriented learning analytics approaches were conducted to reveal the effects of CAM on students' collaborative perceptions, processes, and final products. Results showed that most students made substantive use of the CAM tool and reported positive perceptions of the tool. Further examinations verified the tool's positive effects on improving the students' cognitive engagement levels and the quality of their final collaborative writing products. This research provided practical implications for future CLA tool design and instructional implications for using this type of tool in collaborative learning in higher education.

Active, dutiful and pragmatic: practicing green citizenship in urban China

ABSTRACT This study examines how eco-conscious citizens in urban China negotiate and practice citizenship in the everyday in response to the environmental and climate crises. Drawing on 45 in-depth interviews with participants in a ‘zero waste’ community and virtual observation, I explore how individuals articulate duties and rights, and act to claim their roles as green citizens. I argue that the changing socio-political conditions in China give rise to a particular type of green citizenship that is active, dutiful, pragmatic, and at the same time, gendered and classed. Motivated by a strong sense of duty toward nature and future generations, green citizens set realistic goals, commit to practicing sustainable consumption and building green families and communities. This form of citizenship, however, does not seek the expansion of rights and the enlargement of space for activism. This study offers fresh insights into research on citizenship, sustainable consumption and environmental activism in China.

This article introduces the key theme of the special issue on “satirical activism and youth culture in and beyond COVID-19 China.” It contextualizes the case studies offered by the five articles in the special issue in three key terms: COVID-19, satirical activism, and Chinese youth culture. It asks: What are the new and evolving forms and genres of satirical activism in China, and what is the implication of satirical activism on Chinese youth culture? The article points out the significance of the study of dynamics and politics of the relationship between humor and satire, youth, popular culture, and citizen activism in the era of digital connectivity and vernacular creativity; it calls for more research on the roles of humor and satire in manufacturing and managing consent and opinion.

Spatial and temporal variations in the pollution status and sources of mercury in the Jiaozhou bay

In the past few decades, mercury (Hg) discharged into the coastal bays of China has significantly increased; however, long-term trends regarding the pollution status and sources of Hg in these bays have yet to be clear. Focusing on this issue, surface sediments and core sediments were collected in the Jiaozhou Bay (JZB), a typical bay highly affected by human activities in China, to analyze the concentrations and stable isotopic composition of Hg. Total mercury (THg) concentrations in surface sediment varied from 7 to 163 ng/g, with higher levels located in the eastern JZB, possibly attributed to intensive industrial and population density. THg in sediment cores 14 and 20 displayed fluctuating increasing trends from 1936 to 2019, reflecting the deterioration of Hg pollution. In contrast, THg in sediment core 28 near the river mouth exhibited a declining trend, possibly due to the river dam construction. Using a stable isotope mixing model, contributions of various sources (atmospheric, riverine, and industrial emissions) to Hg in the JZB were estimated. The results showed that industrial emissions were the main source (over 50%) of mercury in the JZB in 2019. Sediment cores recorded an increase in industrial Hg due to early industrialization and Reform and Opening-up before 2000. In addition, sediment core 20 demonstrated a rise in the percentage of riverine Hg due to land reclamation at the bay's mouth during 2000–2007.

Student Development Activities in Chinese Higher Education Institutions: From Assessment to An Enhancement Program

In addition, on the basis of investigation and analysis, the development plan to enhance students' multifaceted ability.By means of questionnaire analysis and interview, this paper collects, collates and analyzes the relevant data of student development activities in Chinese higher education institutions through a questionnaire survey of 100 teachers and 200 students. This enables local researchers to better understand students' needs and challenges, thereby providing strong support for improving students' developmental experiences and learning outcomes. At the same time, the data analysis results can provide an important basis for formulating targeted strengthening plans and improvement strategies, so as to promote the sustainable development of student development activities in China's higher education institutions.

Investigation of Precipitation Process in the Water Vapor Channel of the Yarlung Zsangbo Grand Canyon

Abstract The Yarlung Zsangbo Grand Canyon (YGC) is an important pathway for water vapor transport from southern Asia to the Tibetan Plateau (TP). This area exhibits one of the highest frequencies of convective activity in China, and precipitation often induces natural disasters in local communities, which can dramatically affect their livelihoods. In addition, the produced precipitation gives rise to vast glaciers and large rivers around the YGC. In 2018, the Second Tibetan Plateau Scientific Expedition and Research Program tasked a research team to conduct an “investigation of the precipitation process in the water vapor channel of the Yarlung Zsangbo Grand Canyon” (INVC) in the southeastern TP. This team subsequently established a comprehensive observation system of land–air interaction, water vapor, clouds, and rainfall activity in the YGC. This paper introduces the developed observation system and summarizes the preliminary results obtained during the first two years of the project. Using this INVC observation network, herein, we focus on the development of rainfall events on the southeastern TP. This project also helps to monitor geohazards in the key area of the Sichuan–Tibet railway, which traverses the northern YGC. The observation datasets will benefit future research on mountain meteorology.

Diurnal variation in the urban thermal environment and its relationship to human activities in China: a Tencent location-based service geographic big data perspective.

The main factor of the formation and deterioration in China's urban thermal environment is human activity, which is difficult to describe and measure. A new perspective on the effect of human activity on the urban thermal environment can be obtained by examining the interaction between location-based service (LBS) data and the urban thermal environment in China. However, relevant research is still limited. In this study, we used Tencent LBS data, Terra/Aqua MODIS land surface temperature (LST) data, and land use data to investigate the relationship between LBS and the urban thermal environment, specifically the LST and surface urban heat island intensity (SUHII) across China and its provinces. Our results showed that (1) in summer, the heat island effect was an issue in 94% of the urban areas in China, which was worse during the day. The high- and low-value periods of LBS data on a given day coincided with the acquisition times of MODIS LST products during the day and at night, respectively. (2) During both the day and at night, there was a significant connection between LBS data and the urban thermal environment in China. The highest correlation coefficient (r) between LBS data and the LST could reach 0.55 (p < 0.01) at the provincial level, and the highest correlation coefficient (r) between LBS data and the SUHII could reach 0.78 (p < 0.01) at the provincial level. (3) The urban thermal environment diurnal difference and LBS data exhibited a significant relationship. The ΔLBS diurnal differences were significantly positively related to the SUHII diurnal differences in China. The overall study findings revealed that LBS data constitute an important parameter to represent the human activity intensity when investigating the formation of the urban thermal environment in China.

Natural and anthropogenic impacts on mercury accumulation in Xiaohai Lagoon, South China over the last 1200 years

Anthropogenic use and release of mercury (Hg) have profoundly affected the global Hg cycle since preindustrial times. However, it is often difficult to quantify the relative contributions of natural and anthropogenic factors to environmental Hg accumulation. Here, we have presented a 1200-year record of Hg deposition in a sediment core from the Xiaohai Lagoon (South China), in combination with multiple environmental indicators (e.g., geochemical elements, grain size and total organic carbon, etc.). Using principal component analysis (PCA) and stepwise regression analysis (SRA), we aimed to explore the latent processes governing the accumulation of Hg over time and to quantitatively assess the natural and anthropogenic impacts on Hg deposition over the last millennium in Xiaohai Lagoon. Our results have demonstrated that between ∼ 870 and ∼ 1860 CE, natural factors were the main drivers controlling Hg concentrations in the lagoon. These were directly driven by higher soil erosion and increased inputs of fine-grained matter. However, from 1860 to 2013 CE, enhanced anthropogenic activities played a significant role in Hg accumulation in Xiaohai Lagoon. Anthropogenic Hg fluxes increased significantly from ∼ 1860 CE, peaked several times during the 1860s to the 1950s, accelerated from the late 1950s to the early 2000s, and then declined gradually owing to the stringent environmental protection strategies and efficient pollutant control technologies. Our results have suggested that the increased anthropogenic Hg inputs between the 1860s and mid-1970s were mostly attributed to wars, the “Westernization Movement”, and global industrial activity, with a surge mainly after the 1980s dominated by industrial activities in China and numerous developing countries in Southeast Asia. This study has shown the natural and anthropogenic influences associated with mercury pollution through quantitative analysis and can deepen our understanding of the processes and mechanisms of mercury deposition in natural environments under the influence of human activities.

Exploration of the Methods of Using Mathematics in the Financial Economy of the Enterprise

As a matter of fact, with the development of the times and the advancement of economic system reform, the activity of China's financial market has increased. As a consequence, the financial and economic development is facing new opportunities. In this case, it is necessary to give full play to the role of economic mathematics knowledge. Enterprises in their own business development, need to focus on how to strengthen the financial and economic analysis, a comprehensive display of the advantages of economic mathematics, the use of economic as well as mathematical theories, the financial and economic value of the enterprise for a period of time, usually involving the derivative, differential, function models and other knowledge, can provide support for the formation of the results of the enterprise's financial and economic analysis, which in turn helps enterprises to adapt to the changes in the financial market in a more comprehensive manner contemporarily.

Socio-hydrology pathway of grain virtual water flow in China

As the world's largest grain producer, China's activities in virtual water trade for grain are particularly noteworthy. The imbalance of grain production and consumption among regions poses challenges to agricultural development and the sustainable use of water resources. Most of the previous research focused on the driving analysis of factors affecting agricultural water use at the production end. It is necessary to further explore the driving factors of virtual water flow (VWF) caused by grain trade on the consumption side, and consider the impact of production and consumption on the entire process of agricultural water use. This study combines the Logarithmic Mean Divisia Index (LMDI) index decomposition method and multiple regression model to analyze the main natural and social driving factors of VWF. The study also initiates the construction of an analytical framework for the dynamic interaction of coupled social hydrology and Metacoupling systems. The results indicate that economic growth is the primary driver behind the increase in VWF. The water intensity effect and industrial structure effect act as constraints on VWF. Notably, water intensity has the most significant negative effect, with contributions of − 118.9 Gm³ and − 192.4 Gm³ to the virtual water output and input areas, respectively. Conversely, the economic, demographic, and dependence effect play a promoting role. Among these, the positive economic effect far exceeds population and dependence effects, contributing 189.7 Gm³ and 231.3 Gm³ to the virtual water output and input areas, respectively. The analytical framework of coupled social hydrology and the dynamic interaction of Metacoupling systems reveals that VWF couples water resources with multiple systems through the production-consumption-pollution chain. Simultaneously, it achieves long-distance interactions across spaces through cross-space VWF, exhibiting socio-hydrological interactions. The input area displays a forward cycle, while the output area exhibits the opposite. These findings can serve as a theoretical reference for controlling grain VWF.

Cardiovascular diseases burden attributed to low physical activity in China, 1990-2019

Objective: To analyze the burden of cardiovascular disease (CVD) attributed to low physical activity (LPA) and its changing trends in China from 1990 to 2019. Methods: On the basis of the province results of the Study of Global Burden of Disease 2019 in China, we described the distribution of CVD death and disability-adjusted life year (DALY) attributed to LPA by sex, age and province. Joinpoint 4.9.1.0 was used to calculate the average annual percentage change. Results: In 2019, the number of CVD deaths and DALY attributed to LPA in people aged ≥25 years were 0.127 million and 1.863 million person-years in China, respectively, The age-standardized mortality rate (ASMR) and standardized DALY rate of CVD attributed to LPA were slightly higher in men than in women, and much higher in ischemic heart disease patients than in ischemic stroke patients. The ASMR (8.85/100 000) and the standardized DALY rate (112.34/100 000) of CVD attributed to LPA in China in 2019 showed no obvious change compared with 1990, while decreased in the last decade. The largest increases in the mortality rate and DALY rate were observed in people aged ≥75 years from 1990 to 2019 (26.89%, 15.61%), but the mortality rate and DALY rate in people aged 60-74 years showed a decreasing trend. The mortality rate and DALY rate in men aged 25- 44 years showed the largest increases (37.50%, 35.49%), while women aged ≥75 years had the largest increases (31.00%, 18.02%). In 2019, the highest ASMR and standardized DALY rate of CVD attributed to LPA were found in Jilin, Inner Mongolia and Hebei. The largest increases were found in Qinghai (182.41%, 154.70%), Gansu (181.29%, 152.77%), and Chongqing (132.01%, 102.79%) and the largest decreases were found in Beijing (59.11%, 62.09%), Macau (41.89%, 39.37%) and Guangdong (36.93%, 40.72%) from 1990 to 2019. Conclusion: The disease burden of CVD attributed to LPA in China was quite high and showed gender, age and area specific differences.

Managing the power of images: Environmental NGOs, networked public screens, and ‘interactive’ image events in China

Scholars have researched the ‘wildness’ or ‘tameness’ of public screens for staging image events. This study argues that in non-democratic contexts, public screens are not totally wild or tame but are constrained by institutional limits, straddling the tame and the wild. In networked public screens, activists should keep a careful balance between tameness and wildness, staging ‘interactive’ image events to conduct bottom–up social mobilization to pressure the local state while avoiding being perceived as a threat. Through a case study of environmental activism in China, we identified two interactive strategies that were organized around image events. One was a visible interaction through which activists manipulated the mediated visibility of environmental problems by constructing image events. The other was an invisible interplay through which states and non-governmental organizations (NGOs) engaged in closed-door negotiations to solve the problems exposed, without relinquishing the potential for social mobilization by constructing image events. These two forms of interactions, visible and invisible, form a circuit and are interconvertible in specific situations. With the shrinking of institutional space, invisible interaction is becoming the dominant mode of interaction with the state. The formation of such an interactive circuit has largely constrained the power of environmental images in social mobilization.

Threshold effect of ecosystem services in response to human activity in China's urban agglomeration: a perspective on quantifying ecological resilience.

Ecological resilience reflects the role of human activity intensity (HMI) on regional ecosystem services (ESs), and resilience improvement is crucial for the high-quality development of urban agglomeration areas. However, a theoretical framework for ecological resilience needs to be developed based on ES thresholds under human activities. Based on the threshold index, we used threshold regression model to determine of the nonlinear dominant factors affecting ESs and to identify the priority areas for ecological restoration. The results suggest that (1) CS, HQ, and TES declined, while FP increased. The spatial distribution of each ES showed higher values in the central region and lower values in the surrounding areas. HMI showed a significant upward trend, with expanding high-HMI areas. There is a threshold effect in the relationship between HMI and ESs, leading to variations in their positive, non-monotonic, or non-linear interactions. (2) HMI positively and significantly affects ESs, especially at low threshold levels. The effect of HMI on ESs is negative in counties with higher threshold levels rather than in lower-level grids. (3) The critical area of artificial potential ecological restoration was 712 km2, primarily concentrated around urban; the critical area of natural restoration was 490 km2. Therefore, the threshold in the relationship between HMI and ESs should be given more attention. This study serves as a guide for picking out key regions for territorial ecological restoration.

Avoid the outdoors on polluted days? Evidence from China

ABSTRACT In this paper, we investigate the impacts of air pollution on overall outdoor activities in China. To address the shortcomings of previous studies, which mainly focused on specific outdoor activities, we provide new evidence of people’s avoidance behaviours on polluted days by using road traffic flow as a proxy for overall outdoor activities. Based on a novel daily road traffic flow data covering four major cities in China in 2018, we find that an increase of 100 points in air quality index (AQI) lead to a reduction in road traffic flow by approximately 0.9%. To overcome potential issues of endogeneity problems, we introduce an instrumental variable based on the AQI of surrounding cities weighted by distance and wind direction. A variety of robustness checks validate the causal interpretation of our findings, and further analysis provides richer characterizations of people’s self-protective avoidance behavioural response to air pollution. Our findings are highly valuable for policy-making and provide practical implications to public transport operators.

Association of physical activity with socio-economic status and chronic disease in older adults in China: cross-sectional findings from the survey of CLASS 2020 after the outbreak of COVID-19

BackgroundIn 2021, China had a population of 264·01 million individuals over the age of 60, indicating a high prevalence of chronic diseases. Among older adults, physical inactivity (PI) is a significant risk factor for chronic diseases. However, few studies have been conducted on the correlation of physical activity (PA) with the economic status, geography and chronic disease risks in Chinese elderly. The objectives of this study were to better understand the distribution of PA among older adults in China and its relationship with economic status, geography, and chronic disease risks.MethodsThis study utilized data from the China Longitudinal Aging Social Survey (CLASS) in 2020, post-COVID-19. The study employed a stratified, multistage, probabilistic sampling approach and included 11,396 adults over the age of 59 from 28 provinces in China. Data on demographics, the duration and intensity of PA, history of diseases and personalized factors influencing PA were collected via structured interviews by researchers. In this study, we conducted a comprehensive analysis, employing a range of statistical methods including descriptive analysis, Wilcoxon rank-sum tests, Bayesian networks, and chi-square tests.ResultsThe prevalence of PI among older adults over 59 in China is 28·82%. Significant regional differences were observed in the duration of PA at different intensities. Older adults residing in more economically developed areas were more likely to engage in moderate-to-vigorous physical activity (MVPA) and exhibited longer sedentary behavior. Economic status and urban-rural disparities consistently emerged as direct influential factors across all intensity types. Chronic disease risks were significantly lower in active older adults compared to inactive ones. Lack of social guidance, family support, and personal inclination towards sedentary behavior were the main personalized factors affecting PA among older adults, and these factors could be relatively easily modified.ConclusionsEconomic status, geography, and living areas (urban and rural) significantly influenced the distribution of physical activities in China. Particularly, economic status and living areas acted as direct factors. Older adults reaching the recommended standards for PA had significantly lower chronic disease risks, highlighting the importance of improving personalized factors which are crucial for promoting PA.
