Evaluation of Green Logistics Efficiency in Jiangxi Province Based on Three-Stage DEA from the Perspective of High-Quality Development

The high-quality development of the logistics industry plays an important role in high-quality economic development. Green logistics is attracting more attention, owing to environmental concern. Based on the five concepts of “innovation, coordination, green, openness and sharing” of high-quality economic development, the input–output indicators of green logistics efficiency (GLE) have been designed. The correlation between the green logistics input and output indicators have been analyzed by Pearson, and the green logistics efficiency of 11 cities in Jiangxi Province has been calculated by three-stage DEA. The evolutionary characteristics of the high-quality development of green logistics efficiency in Jiangxi Province were analyzed and evaluated. The conclusions were achieved as follows: (1) Nanchang, Xinyu and Ganzhou city are at the forefront of efficiency, and are less affected by environmental factors. The logistics efficiency of other cities is obviously affected by environmental factors. (2) The comprehensive technical efficiency (TE) of green logistics in Jiangxi Province is strongly influenced by scale efficiency (SE). The poor scale efficiency reduces the comprehensive technical efficiency of green logistics. (3) There is a positive correlation between high-quality economic development and logistics efficiency. In these cities of Jiangxi province (Nanchang, Ganzhou, Jiujiang, etc.) the share of total economy and green logistics efficiency is high. This study proves that Jiangxi province is moving towards high-quality economic development due to good environmental protection. (4) In 2017, Jiangxi Province was recognized as one of the national ecological civilization pilot region by the State Council. Green logistics efficiency in Jiangxi Province showed an inflection point in 2017, indicating that the green concept is becoming more and more popular. From the government to enterprises, the province has achieved initial results in promoting the transformation of the economic development mode. It aims to provide reference for the high-quality development of other provinces.

A re-assessment of metal pollution in the Dexing mining area in Jiangxi province, China: current status, hydro-geochemical controls, and effectiveness of remediation practices

This study re-assess the environmental impacts of the Dexing copper mine (the largest open-pit copper mine in Asia) on the Lean river and its two tributaries (the Dawu river and Jishui river) in the Jiangxi province, China, with particular focus on metal pollution as well as the effectiveness and side-effects of remediation activities. Results show that the Dawu river and its mixing zone with the Lean river were still heavily influenced by acid mine drainage (AMD) and loaded with elevated levels of metals, in particular Mn, Ni, and Al whose concentrations were frequently above the health-based guideline values. Manganese and Ni in the AMD-impacted waters were predicted to occur as free ions or sulfate and carbonate complexes, and thus highly-toxic to living organisms. Although Al in the AMD-impacted waters was predicted to exist largely as colloidal hydroxides with low bioavailability, abundant formation of such nano-sized particles could impair the respiratory and circulatory systems of aquatic macro-invertebrates. The integration and comparison of the results from the current and previous studies show that the concentrations of several metals (Cu, Zn, and Cd) in the Dawu river decreased significantly after 2011–2012, during which several remediation practices were implemented (e.g., AMD neutralization, excavation of contaminated sediments in impounded rivers, and rehabilitation of mine tailings and open-pit slopes). This provides evidence that these remediation practices have effectively limited the dispersion of metals from the mining area. However, AMD neutralization greatly enhanced the release of sulfate, making the mining area an even more important sulfate source.

Artificial Intelligence in the Protection and Inheritance of Cultural Landscape Heritage in Traditional Village

To continue to protect and inherit the cultural landscape heritage of traditional villages, starting from the perspective of artificial intelligence (AI), literature review methods are used, and related theories are collected. Then, Wuyuan County in Jiangxi Province in the traditional villages is taken as the research object. By analyzing the tourism income of this place from 2016 to 2020, the overall income of this county is relatively good. In fact, due to the weak protection of traditional villages in Wuyuan County, the lack of supervision awareness, the implementation of the “immigrant and relocation” policy, and the backward thinking of residents, the cultural landscape of traditional villages has collapsed and destroyed. Up to now, there are 113 ancient ancestral temples, 28 ancient mansion houses, 36 ancient private houses, 187 ancient bridges, and only 12 ancient villages. Finally, AI technology is applied to the cultural landscape of traditional villages. Through image restoration technology, traditional villages can be restored to a certain extent. Intelligent positioning and radio frequency (RF) technology can also realize real-time monitoring of traditional villages from the perspective of weather and service life to achieve the purpose of protecting cultural landscape heritage. Therefore, AI technology is applied in the protection and inheritance of traditional village cultural landscape heritage, which has great reference significance for the management of various historical and cultural heritage.

Construction and Application of the Evaluation System of Natural Resources Asset Accountability Audit of Officials: A Case Study of Jiangxi, China

At the Third Plenary Session of the 18th Central Committee of the Communist Party of China, the Central Committee first proposed the establishment of the Natural Resources Asset Accountability Audit of Officials, which not only marked a new stage in China’s ecological construction, but also triggered many scholars’ discussion on the accountability audit evaluation indicator system of natural resources assets. In this paper, the combination of entropy weight method and TOPSIS method is introduced into the natural resource asset accountability audit evaluation system for the first time, and a system based on energy subsystem, economy subsystem and environment subsystem is constructed. The system is used to evaluate the performance of leading officials of Jiangxi Province, one of the first batch of national pilot zones for ecological conservation in China, in the responsibility of natural resource asset management from 2015 to 2019. The evaluation result indicates that the overall situation of natural resource assets in Jiangxi Province shows a steady upward trend, and the overall performance should be affirmed. The practical application of this evaluation system in the national pilot zone for ecological conservation will enlighten other provinces in China to improve the leading officials’ accountability audit of natural resource assets.

Factors Affecting the Knowledge Sharing Behaviors of University Teachers: An Empirical Study in China

Knowledge sharing among teachers denotes an important means of promoting the professional growth of individual instructors. It enhances the competitiveness of school organizations and thus constitutes a focal aspect of knowledge management in universities. This study conducts an in-depth scrutiny of the knowledge sharing behaviors of teachers, examining their sharing intentions and attitude, support received from others, self-control. With this aim, this paper obtains data from 440 college teachers in Jiangxi Province in China. It then constructs a theoretical model reflecting these factors, and the collected data were analyzed through SPSS24 and AMOS24 to obtain the results. The results of this empirical study conducted in China demonstrate that the knowledge sharing intentions of teachers positively influence their knowledge sharing behaviors. Personal knowledge sharing attitudes and support received from others also constructively affect the knowledge sharing intentions of teachers. Self-control has a negative effect on knowledge sharing intentions and exerts an indirect influence on knowledge sharing behaviors. Knowledge sharing attitudes, support received from others, and self-control are strongly and positively correlated. This investigation suggests that the knowledge sharing intentions of teachers must first be enhanced to improve their knowledge sharing behaviors. The enthusiasm of teachers to share knowledge should be stimulated, and teachers should be encouraged to freely share their understanding with others. Further, their tight regulation of self-control should be appropriately relaxed.

Analysis of Government Support, Network Adaptability and Online Sales Adoption Behavior of Fruit Farmers: Based on the Survey Data of Gannong

Online sales are an important part of agricultural product sales channels under the background of rural revitalization in the new era. Online sales play an active role in invigorating the agricultural product market, solving the problem of connecting small production with big market and promoting farmers' income, agricultural efficiency and rural welfare. Based on the field survey data of 511 fruit farmers in Jiangxi Province, this paper empirically analyzes the influence of government support and network adaptability on online sales behavior of fruit farmers by using binary Logistic model. The results show that the government's implementation of operating subsidies, preferential taxes and fees and technical training are helpful for fruit farmers to adopt online sales; Network adaptability can significantly positively affect online sales of fruit farmers, and at the same time, there is a positive adjustment between government support and online sales behavior of fruit farmers; By implementing various support measures, the government helps to improve the adaptability of fruit farmers' network, and further has a significant positive impact on fruit farmers' adoption of online sales behavior. The results provide theoretical basis for the relationship among government support, network adaptability and online sales of fruit farmers, and provide practical enlightenment for the government and fruit farmers.

Sporidesmiella lignicola sp. nov., a new hyphomycetous fungus from freshwater habitats in China

Freshwater fungi, growing on submerged wood, can promote the degradation of organisms and the reuse of rotten wood energy and play key roles in freshwater ecosystems. Here, a new hyphomycetous fungus, Sporidesmiella lignicola, was isolated and identified from submerged wood samples collected in a small stream in Jiangxi Province, south-eastern China. The new taxon was studied, based on morphological characters and phylogenetic analyses combined with LSU, ITS, TEF1α and RPB2 sequences data. Sporidesmiella lignicola was morphologically characterised by its pink colonies on PDA medium in prophase, macronematous, mononematous, solitary, brown, septate, unbranched, straight or slightly flexuous conidiophores with holoblastic, polyblastic, integrated, terminal, pale brown conidiogenous cells and cylindrical, narrowly clavate, broadly obovoid to cuneiform, 3–4-distoseptate, olivaceous brown or brown conidia with rounded apex. A phylogenetic tree was constructed, based on the combination of LSU, ITS, TEF1α and RPB2 sequences data.

Diverse labechiid stromatoporoids from the Upper Ordovician Xiazhen Formation of South China and their paleobiogeographic implications

A diverse labechiid stromatoporoid assemblage that includes 16 species in 8 genera was found in the Upper Ordovician Xiazhen Formation (mid–late Katian) at Zhuzhai, Jiangxi Province of South China. The assemblage is characterized by a combination of (1) North China provincial species succeeding from their origination in the Darriwilian, including Pseudostylodictyon poshanense Ozaki, 1938, Labechia shanhsiensis Yabe and Sugiyama, 1930, Labechia variabilis Yabe and Sugiyama, 1930, and Labechiella regularis (Yabe and Sugiyama, 1930) and (2) South China endemic species, including three new species (Labechia zhuzhainus Jeon n. sp., Labechiella beluatus Jeon n. sp., Sinabeatricea luteolus Jeon n. gen. n. sp.), and four species in open nomenclature (Rosenella sp., Cystostroma sp., Pseudostylodictyon sp., and Labechia sp.). The finding of Labechiella gondwanense Jeon n. sp., Stylostroma bubsense Webby, 1991, Stylostroma ugbrookense Webby, 1991, and Thamnobeatricea gouldi Webby, 1991 in the formation indicates that Tasmania was closely related to South China and had a closer paleobiogeographical relation with peri-Gondwanan terranes than with Laurentia. In addition, the occurrences of Labechia altunensis Dong and Wang, 1984 and Stylostroma species support a close biogeographic link between Tarim and South China through the Middle to Late Ordovician interval, corresponding with the results from other fossil groups such as brachiopods, conodonts and chitinozoans. The diverse labechiids from the Xiazhen Formation improve our understanding of the diversity of Ordovician stromatoporoids in peri-Gondwanan terranes and the biogeographic affinities among Australia (especially Tasmania), Tarim, and South China.

Family Resilience, Media Exposure, and Children's Mental Health in China During COVID-19

This study aims to describe children's mental health conditions in the time of COVID-19 and its associations with the risk factor (media exposure) and the protective factor (family resilience) during COVID-19. The study took place from February 13th to February 29th, 2020, at the peak of the outbreak all across China. In total 441 children (M = 11.83 years old, SD = 0.79) from Jiangxi province, China, filled out online surveys. The results showed that children's rates of depression were relatively high and post-traumatic stress disorder (PTSD) rates were low. Based on the results of multiple linear regression analyses, family resilience was negatively associated with children's mental health issues including depression, anxiety, PTSD, and poor sleep quality counting the effects of children's age, gender, and media exposure. Children's media exposure to COVID-related news reports did not significantly contribute to the total variance of children's mental health symptoms. The findings guide the development of prevention and interventions to mobilize families’ strengths and resilience for reducing children's maladjustment during the occurrence of pandemics.
