Rice and Greenhouse Identification in Plateau Areas Incorporating Sentinel-1/2 Optical and Radar Remote Sensing Data from Google Earth Engine
Authors: Zhang Tao , Tang Bo-Hui , Huang Liang , Chen Guokun
Published: November 2022

Affected by geographical location and climatic conditions, crop classification in the Yunnan Plateau of China is greatly restricted by the low utilization rate of annual optical data, complex crop planting structure, and broken cultivated land. This paper combines monthly Sentinel-2 optical remote sensing data with Sentinel-1 radar data to minimize cloud interference to conduct crop classification for plateau areas. However, pixel classification will inevitably produce a “different spectrum of the same object, foreign objects in the same spectrum”. A principal component feature synthesis method is developed for multi-source remote sensing data (PCA-MR) to improve classification accuracy. In order to compare and analyze the classification effect of PCA-MR combined with multi-source remote sensing data, we constructed 11 classification scenarios using the Google Earth Engine platform and random forest algorithm (RF). The results show that: (1) the classification accuracy is 79.98% by using Sentinel-1 data and 91.18% when using Sentinel-2 data. When integrating Sentinel-1 and Sentinel-2 data, the accuracy is 92.31%. By analyzing the influence of texture features on classification under different feature combinations, it was found that optical texture features affected the recognition accuracy of rice to a lesser extent. (2) The errors will be reduced if the PCA-MR feature is involved in the classification, and the classification accuracy and Kappa coefficient are improved to 93.47% and 0.92, respectively.

Published: November 2022

Controlling environmental noise and reducing excessive noise is necessary to protect human health and provide auditory comfort. People are frequently exposed to traffic noise in their daily life and traffic noise is a considerable problem on the city scale. This study investigates the sound absorption coefficient in asphalt pavements so as to reduce traffic and environmental noise. The important parameters affecting the sound absorption coefficient in asphalt pavement, such as the use of porous asphalt pavements, clogging pores, the mixture content change, the thickness change, and getting wet, were identified. It is stated that the sound absorption coefficient in the asphalt layer can be increased with the use of a porous asphalt layer, and by changing the thickness and mixture content. In addition, with the effects of global warming, water supply problems are observable in cities. In this context, the use of rainwater is of vital importance. Permeability of the asphalt layer and storage of rainwater in the lower layer are recommended. The accumulation of rainwater with the aid of drainage in porous asphalt pavements has been investigated and the use of rainwater within the scope of recycling is explored. Within the scope of the research, the construction of porous asphalt pavements is suggested in a system that can store water, reuse rainwater with a new system proposal, and reduce environmental noise by increasing sound absorption performance. Accordingly, it will be possible to reduce the environmental noise level and to use rainwater within the scope of recycling. According to varying thicknesses, porous asphalt pavements were modeled using the finite element method, and the Von Mises stress and vertical deformation results of different thicknesses were compared.

Published: November 2022

The main purpose of this study was to investigate whether work engagement mediates the relationship between job crafting and job performance. To this end, the following hypotheses were formulated: (1) job crafting establishes a positive and significant association with job performance; (2) job establishes a positive and significant association with work engagement; (3) work engagement establishes a positive and significant association with job performance; (4) work engagement mediates the association between job crafting and job performance. The sample was composed of 453 participants working in organisations based in Portugal. The hypotheses formulated in this study were tested by performing simple and multiple linear regressions. The results indicated that only increasing structural job resources and increasing challenging job demands established a positive and significant association with task performance. Increasing structural job resources, increasing social job resources, and increasing challenging job demands established a positive and significant association with citizenship performance and work engagement. Work engagement established a positive and significant association with task performance and citizenship performance. Only a partial mediating effect, through work engagement, was observed on the association between increasing challenging job demands and task performance, and between increasing social job resources and citizenship performance.

Authors: Kele Tumo Paulus , Makhetha Mokheseng
Published: November 2022

Despite the importance of the logistics sector to the South African economy and the significant negative impact of the sector on South African society, little research has been conducted to determine the extent to which South African logistics companies report their social sustainability and the effectiveness of their social sustainability reporting. The objectives of this study were to determine the extent to which South African logistics companies report on social sustainability performance and to evaluate the effectiveness of social sustainability reporting practices of South African logistics companies. A documentary analysis of the sustainability information of the logistics companies was conducted using a control list and a judgment scale. A purposive sample of 50 companies was used. The majority of the companies in the sample are private companies that are not listed. Of the sample group, 20% are family-owned, and 16% of the companies are publicly listed in the Johannesburg Stock Exchange (JSE). The results indicate that social sustainability reporting by logistics companies is very low. The range of scores is from a minimum of 0% to a maximum of 57%. Only two companies attained a score above 50%. About 61% of the companies did not disclose any of the stated themes of social sustainability, while 25% of the companies disclosed the themes in narrative form, and 12.1% disclosed them relative to prior periods of disclosure by the companies. Only 1.4% disclosed themes relative to the targets set by the company, and 0.3% of the companies disclosed them relative to industry standards. Regarding the effectiveness of social sustainability reporting, nine companies (18%) had a score of 50% and above. Only 13 companies (26%) have a score of 40% or higher. This is indicative of the fact that, in general, road logistics companies are not effective in their reporting of social sustainability activities. We endeavour for the study to assist South African logistics companies in being aware of elements to consider when reporting on their social sustainability, as well as assist them in improving their reporting.

Published: November 2022

The quality assessment and grading of agricultural products is one of the post-harvest activities that has received considerable attention due to the growing demand for healthy and better-quality products. Recently, various non-destructive methods have been used to evaluate the quality of agricultural products, which are very desirable and faster and more economical than destructive methods. Optical methods are one of the most important non-destructive methods that use the high speed of light detection and computer data processing and are able to evaluate the quality and classification of products with high accuracy. Among the optical methods, visible–near-infrared (Vis/NIR) spectroscopy is considered one of the most accurate methods. In this research, Vis/NIR spectroscopy technology was used in the spectral range of 350–1150 nm for non-destructive detection of some quality parameters including pH, TA, SSC, and TP of two varieties of Red Delicious and Golden Delicious apples. Various pre-processing models were developed to predict the parameters, which brought the desired results with high accuracy so that pH prediction results were for yellow apples (RMSEC = 0.009, rc = 0.991, SDR = 2.51) and for red apples (RMSEC = 0.005, rc = 0.998, SDR = 2.56). The results for TA were also (RMSEC = 0.003, rc = 0.996, SDR = 2.51) for red apples and (RMSEC = 0.001, rc = 0.998, SDR = 2.81) for yellow apples. The results regarding SSC were for red apples (RMSEC = 0.209, rc = 0.990 and SDR = 2.82) and for yellow apples (RMSEC = 0.054, SDR = 2.67 and rc = 0.999). In addition, regarding TP, the results were for red apples (RMSEC = 0.2, rc = 0.989, SDR = 2.05) and for yellow apples (RMSEC = 1.457, rc = 0.998, SDR = 1.61). The obtained results indicate the detection of the mentioned parameters with high accuracy by visible/infrared spectroscopic technology.
Experimental Study on Permeability Evolution of Deep Coal Considering Temperature
Authors: Wang Xiangyu , Zhang Lei
Published: November 2022

With the depletion of shallow mineral resources, the sustainable development and utilization of deep mineral resources will become a normal activity. As a type of clean energy to promote sustainable development, gas in deep coal seams has attracted wide attention. A better understanding of the permeability evolution induced by mining disturbance and the geological environment is of great importance for underground coal exploitation and gas extraction. In order to analyze the evolution of the mechanical properties and permeability of deep coal that are induced by high ground temperature, coal of the Pingdingshan Coal Mine has been investigated, and the seepage tests were carried out by keeping the confining pressure constant and loading and unloading axial stress under different temperature conditions. The effect of temperature on the peak strength and the initial elastic modulus of coal samples is analyzed. The evolution of permeability, which is estimated with the transient pulse method, based on fractional derivative and fracture connectivity, are discussed by establishing the relationship between fracture connectivity and fractional derivative. Meanwhile, the damage variable that is caused by stress and temperature is introduced and the contribution of thermal damage on coal damage accumulation is discussed. A theoretical model is proposed regarding permeability evolution with temperature and stress based on the Cui–Bustin model, which is verified by experimental data. It has been found that the strength and elastic modulus of deep coal decrease nonlinearly with increasing temperature, which demonstrates that temperature has a weakening effect on the mechanical properties of coal. The fracture connectivity and permeability evolution trends with axial strain are consistent under different temperatures, which decrease slowly in the compaction and linear elastic stages, reach the minimum at the volumetric dilation point, gradually increase in the yield stage, then have a sharp increasing trend in the post-peak stage and, finally, become steady in the residual stage. The damage induced by temperature increases with rising temperatures under different external load conditions. When the external load increases gradually, the thermal damage still accumulates, but the thermal damage variable ratio decreases. The proposed permeability model considering temperature and stress can describe the trend of the experimental data. With axial stress increasing, the influence of temperature on permeability decreases, and its leading effect is mainly reflected in the compaction stage and the linear elastic stage of coal.

Authors: Li Rui , Chen Xin
Published: November 2022

Reverse logistics is attracting attention due to the increasing concerns over environmental issues and the important economic impacts. The design of a reverse logistics network is a major strategic problem in the field of reverse logistics. As cost pressures in product returns continue to mount, a growing number of manufacturers have begun to outsource reverse logistics operations to third-party logistics (3PL) providers. On the other hand, considering disruption risks caused by natural or man-made factors in the reverse logistics network design is inevitable. This paper studies third-party reverse logistics network designs under uncertain disruptions. The problem is formulated as a risk-averse two-stage stochastic programming model with a mean risk objective. Two types of risk measures, value at risk (VaR) and conditional value at risk (CVaR), were examined, respectively. Finally, the sensitivity analysis of the model was carried out. The validity of the mean risk criteria is proved by comparison with risk-neutral approach. Moreover, the performance of the proposed model was examined by stochastic measures.

Authors: Yang Fandi , Yuan Peng , Jiang Gongxiong
Published: November 2022

The knowledge spillover theory of entrepreneurship (KSTE) predicts a positive relationship between knowledge creation and entrepreneurial activity. As a transitional economy, China exhibits great differences among regions in advancing market reforms and opening-up, largely due to the gradual nature of its economic transformation and opening-up. This situation provides a suitable setting for exploring the role of the institutional environment in the KSTE framework. In this study, we discuss the applicability of the KSTE in the Chinese context and theoretically analyze the role of the institutional environment from aspects of market reforms and opening-up. An empirical analysis based on the data of the Chinese manufacturing sector shows that the KSTE is applicable in China and it is applicable to industries with different technology levels and regions with different levels of economic development. More importantly, we find that both market reforms and opening-up strengthen the positive effect of knowledge creation on entrepreneurship. Our exploration in this field extends the KSTE.

Published: November 2022

Affected by global warming, methane gas released by permafrost degradation may increase the frequency of wildfires, and there are few studies on wildfires in permafrost regions and their correlation with climate and regional methane emissions. The northwestern section of the Xiaoxing’an Mountains in China was selected as the study area, and the spatial relationship between permafrost and spring wildfires was studied based on Landsat TM and Sentinel-2 data. Combined with monitoring data of air temperature, humidity, and methane concentration, the impact of methane emissions on spring wildfires was analyzed. The study shows that the spatial distribution of fire scars in spring is highly consistent with permafrost, and the change trend of fire scars is in line with the law of permafrost degradation. Wildfires occur intensively during the snow melting period in spring, and the temporal variation pattern is basically consistent with the methane concentration. The number of fire points was positively correlated with air temperature and methane concentration in March and April, and spring wildfires in permafrost regions are the result of a combination of rising seasonal temperatures, surface snow melting, and concentrated methane emissions. Larger areas of discontinuous permafrost are more prone to recurring wildfires.
The Effects of Meridian Surface Shape on the Pressure Pulsation of a Multi-Stage Electric Submersible Pump

Published: November 2022

The influence mechanism of the internal pressure fluctuation propagation law of multi-stage submersible electric pump (ESP) is still unclear, which has been a major problem restricting the stable exploitation of deep-sea oil and gas. In order to investigate the effect of different meridian profiles on the pressure pulsation characteristics of three-stage submersible electric pumps, the unsteady Reynolds-averaged Navier–Stokes (URANS) method is used to numerically investigate it. The results show that the lower the pressure pulsation amplitude in the pump caused by the meridional shape that is more in line with the flow law, has a positive effect on the operation stability. The change of the shape of the meridian greatly affects the pressure pulsation law in the secondary and final pumps. The rotor–stator interaction causes the pressure pulsation amplitude of the monitoring point in the middle of the pump chamber to reach a peak value. By using continuous wavelet transform analysis, it is found that the regularity of 1–2 times frequency conversion is complicated due to multiple pulsation sources and low frequency propagation coupling between stages. At 3–6 times frequency, it is basically close to the pulsation rule of the blade frequency. The above research provides a basis for improving the operation stability of the ESP.

Published: November 2022

Steel slag is generally regarded as a supplementary cementitious material in cement-based materials, which is conducive to the realization of the goal of carbon peak and carbon neutralization. However, the lower cementitious activity and poorer volume stability of steel slag limit its high dosage in cement-based materials. In this paper, steel slag ultrafine powder (SSUP) was prepared in the laboratory through mechanical activation combined with grinding aids. Furthermore, the grinding time was optimized. The particle size, specific surface area, and microstructure characterization were evaluated for the SSUP compared with steel slag powder (SSP). The hydration properties of SSUP were studied by means of cement paste hydration heat and mortar strength. Meanwhile, the soundness of SSUP and SSP was compared by the Le chatelier soundness test. The process of preparing SSUP in the laboratory is as follows: the steel slag is ground by a horizontal ball mill for 50 min and then ground with a planetary ball mill mixing with the grinding aids for 15 min. The experimental results show that the hydration degree and rate of SSUP are better than that of SSP, and the activity index of SSUP is 94.19%, which is much higher than that of SSP (69.62%). The X-ray diffractometry (XRD) result shows that the content of the hydration products for SSUP is higher than that of SSP. The soundness test shows that the stability of SSUP is superior to that of SSP when the dosage is the same. Therefore, ultra-fining can effectively improve the cementitious activity and soundness of steel slag.

Published: November 2022

Foamed concrete (FC) is a lightweight building material widely used in thermal insulation walls, backfill, and other fields. Generally, foamed concrete is prepared using cement, which consumes a lot energy and resources. In this study, three kinds of special soil (SS) and slag powder (SP) were used to prepare foamed concrete. The content of SS was 25%, and the content of SP was 35%, 45%, and 55%. The mechanical properties, durability properties, and microstructure of special soil-slag foamed concrete (SSFC) were studied. With the increase in SP content, the water absorption and drying shrinkage of SSFC increased and the compressive strength of SSFC decreased. The water stability coefficients of SSFC were all higher than 0.7, which met the requirements of engineering applications. The porosity and the average diameter of pores of SSFC increased with the increase in SP content. The porosity of SSFC was less than 46% when the replacement percentage of SP was less than 35%. The successful application of SS and SP in foamed concrete provides an effective approach to waste utilization.

Published: November 2022

Sustainable development in arid and semi-arid areas is largely constrained by water resources. Expanding ecological space is considered an effective way to conserve water resources. The innovation of this study is the analysis of water consumption in different land-use types from a complete watershed scale, which can evaluate space management against the background of returning farmland to forestland during the past 20 years, and provide suggestions for future space management in semi-arid areas. Based on meteorological data and GIS technology, the current study quantitatively analyzes the spatial and temporal variation characteristics of the water consumption of different vegetation growth stages in the Yanhe River Basin by using the improved Penman formula. The results show that the water consumption of vegetation in the Yanhe River Basin increased from 0.44 km³ in 2000 to 0.68 km³ in 2020. The water consumption of vegetation showed obvious spatial heterogeneity, with the highest value in the central Baota area (1.094 km³) followed by the western Ansai region (0.727 km³), whereas the consumption in the eastern Yanchang area is relatively low (0.483 km³). In addition, the annual average water consumption is (0.381 km³). The cultivated land consumes the most water (0.21 km3), while the woodland consumes the least (0.072 km³). The water consumption per unit area of forested land is the highest, reaching 190 m, and the water consumption of low-coverage grassland is the lowest, only reaching 50 m. Vegetation distribution change could be the main influencing factor of vegetation water consumption change in the Yanhe River Basin. Through the establishment of the sustainable development path of ecological space with water as the core, the high-quality development of ecological environments in arid and semi-arid areas will be achieved.

Published: November 2022

Edaphic properties have been widely shown to influence community composition and distribution. However, the degree to which edaphic factors can affect grasses in semi-arid lowlands is still little researched. We assessed the significance of nine edaphic factors to explain the distributions of 65 grass species with various ecological traits (i.e., the ecological indicator values for their preferred habitat) in the semi-arid lowlands of Pakistan. To record information on species composition and related ecological conditions, we selected 10 random sampling locations between 2020 and 2021. For each species, we determined the important value index (IVI) and looked at the primary indicator species that were identified using the indicator species analysis approach. The major genera were Setaria, Brachiaria, and Cenchrus with 6.15% species in each followed by Aristida, Panicum, and Eragrostis with 4.61% wild grass species, Bothriochloa, Bromus, Phragmites, Polypogon, Saccharum, Poa, Echinochloa, and Dactyloctenium with 3.07% species, whereas other genera had a single species each. In total, 80% of the species were native, while only 20% were introduced species. Microphylls accounted for 49.23% of the leaf size spectra of the grass flora in the study area. The other frequent traits included macrophylls (21.53%), nanophylls (20%), and leptophylls (9.23%). The major life forms were therophytes (56.92%) followed by hemicryptophytes (38.46%) and geophytes (4.61%). The results of an ordination analysis indicated that the distribution of grasses was significantly (p ≤ 0.002) influenced by several edaphic parameters, with pH having the greatest impact on species distribution. The analyses of indicator species showed that pH and EC were the most powerful and important edaphic factors for determining the composition of plant communities and indicator species. The significant indicator species in various ecosystems were Cynodon dactylon (L.) Pers. rainer.bussmann@smnk.de and Leptochloa chinensis (L.) Nees (agroecosystem), Brachiaria reptans (L.) C.A. Gardner and C.E. Hubb, Dichanthium annulatum (Forssk.) Stapf, and Saccharum spontaneum L. (forest ecosystem), Cenchrus biflorus Roxb., Cenchrus ciliaris L., and Desmostachya bipinnata (L.) Stapf (urban ecosystem), Arundo donax L., Echinochloa crus-galli, and Phragmites australis (wetland ecosystem), and Saccharum spontaneum and Echinochloa crus-galli (L.) P. Beauv. (riparian ecosystem). We discovered that different species groupings had different habitat preferences and that soil pH had a significant beneficial effect on plant variety. These results provide a scientific roadmap for soil and plant restoration in semi-arid lowland habitats.

Published: November 2022

The geological structure, such as inclusions, may strongly affect the wave propagation and underground motions during earthquakes. Previous studies mainly focus on geological inclusion with the homogeneous medium. In this paper, the propagation and scattering of incident plane SH waves in and around an inhomogeneous cylindrical inclusion with a radially-varying modulus is studied. In terms of a radial wave function expansion, a rigorous analytical approach is formulated for general computation for the elastodynamic problem. A comprehensive set of numerical examples are presented to illustrate the sensitivity of the underground motion to the rigidity profile of the geological inclusion.

The current study aims to identify the factors associated with anxiety and depression in patients with acute coronary syndrome (ACS) at hospital discharge from a Peruvian health center. Patients at discharge from the cardiology hospitalization service between November 2019 and December 2020 were evaluated using a cross-sectional study. The median time elapsed from the ACS event to the interview date was 10 months. A total of 34.1% of the population presented mild depression and 78.8% had mild anxiety. All three of our analyses indicated that patients who had attended university had significantly lower levels of both depression and anxiety, and patients with diabetes had significantly higher levels of anxiety. The lower-low socioeconomic group had 1.5 times the frequency of depression (p-value = 0.002) and 3.12 times the frequency of anxiety (p-value = 0.050). Interestingly, while a good quality of life was associated with lower levels of depression, it was also associated with higher levels of moderate/severe anxiety (p-value = 0.035). A multiple regression analysis found that hypertension was also associated with higher levels of anxiety, and patients who have had COVID-19 had 21.05 times the level of moderate/severe anxiety (p-value = 0.000). Cases of ACS are more frequent in patients with an age greater than or equal to 60 years, as well as in males. Isolation was a common feature that may have a negative impact on their quality of life and mental health.

Published: November 2022

Fish assemblages inhabiting the Taizi River basin have been severely degraded by anthropogenic disturbances, which weaken the basin’s ecological function and limited revitalization of the northeast industrial base. Long-term ecological rehabilitation has been conducted to restore the fish fauna and improve habitat conditions. To explore fish distribution patterns and key factors after this ecological rehabilitation, a comprehensive and detailed survey of fish fauna was conducted twice in 2021 at 33 sampling sites in the Taizi River. A total of 50 fish species from 13 families were collected, and the dominant species were P. lagowskii, Z. platypus, C. auratus and P. parva. Compared to results reported over the last decade, the increasing trend in fish richness and the change in the longitudinal fish organization were detected. The abundance variation for P. lagowskii, Z. platypus, C. auratus, P. parva, R. ocellatus and H. leucisculus along the upstream to downstream axis contributed most to the fish distribution pattern. Species replacement and addition might have jointly caused the longitudinal changes in the fish fauna, but species replacement was the main underlying mechanism. The canonical correspondence analysis (CCA) results show that the fish structure pattern was mainly shaped by cultivated land coverage and urban land coverage. Our study provides reference sites for future fish-based bioassessment and implications for region-specific management in the Taizi River.
Investment and Rapid Climate Change as Biopolitics: Foucault and Governance of the Self and Others through ESG
Authors: Luke Timothy W.
Published: November 2022

Environmental, social and governance (ESG) investment strategies today are an established practice in personal and public finance. They also provide crucial benchmarks for corporate social responsibility policy in gauging the performance of due diligence and return on investment by financial managers. This study explores the growing conflict within these economic and policy networks over “value-oriented”, or total financial return, and “values-oriented”, or comprehensive non-financial impact, capital investment in recent years. How to balance these two discursive constructions of value in the pursuit of “sustainability” for both the economy and the environment at the same time is an operational challenge that managers, environmentalists and scientists have not yet fully answered. It also indicates how Michel Foucault’s approach to the power/knowledge nexus in biopolitics provides a useful perspective on these ideologically and politically charged debates over how to invest capital and steer business activity to deliver solid returns in the market as well as support more ethical and economical public policies to respond to climate change, social injustice and governance failure.
ERSDMM: A Standard Digitalization Modeling Method for Emergency Response Based on Knowledge Graph
Authors: Liu Wenling , Yang Yuexiang , Tu Xinyu , Wang Wan
Published: November 2022

Standard digitalization is a crucial step in social and economic development and the transformation of digital technology. Standard digitalization is of great significance in the promotion of sustainable economic and social development. This paper proposes a standard digitalization modeling method for emergency response (ERSDMM) based on knowledge graph (KG). Firstly, this paper analyzes the knowledge structure of emergency response standards (ERS) and constructs a “seven-dimensional” model of ERS based on the public safety triangle theory. An ontology model of the emergency response domain is then created. Secondly, ERS and emergency scenario fine-grained knowledge are extracted. Thirdly, a standard reorganization model is constructed to meet the needs of the scenario response. Finally, the ERSDMM is applied to the GB 21734-2008, which proves that the ERSDMM is available. Taking RES as an example, this paper explores the path and practice of standard digitalization. ERSDMM solves standards-related problems, such as overlapping content, coarse knowledge granularity, incomplete coverage of elements, and difficulty in acquiring knowledge.

As a new industry in modern agriculture, leisure agriculture has a strong correlation with rural tourism, and provides rural areas with positive prospects for sustainable development. However, leisure agriculture tends to include a number of bottlenecks. In this study, we investigated the spatial distribution of leisure agriculture in Xinjiang, and the factors that affect it. Kernel density analysis, the nearest-neighbor index, and the geographic concentration index were used to analyze the distribution characteristics of leisure agriculture. Following the conclusion of the ordinary least squares tests, geographically weighted regression (GWR) was conducted to explore the factors affecting spatial distribution. The findings were as follows: (1) The spatial distribution of leisure agriculture in Xinjiang is uneven, and is concentrated in the northern and southern parts of the Tianshan Mountains in western Xinjiang. (2) In terms of the distribution density, there are four high-concentration centers (Bosten Lake, Hami, and the east and west sides of the Ili River Valley) and one subconcentration center (spreading outward from Urumqi). (3) Population, transportation, tourism resources, urban factors, and rainfall, all had significant effects on the distribution of leisure agriculture. These factors had positive and negative effects on the distribution of leisure agriculture, forming high- and low-value areas in space. (4) The leisure agricultural sector responded in varying degrees to the different factors, with large internal variability. Rainfall and population had greater differential effects on the spatial distribution of leisure agriculture compared to transportation, tourism resources, and urban factors, and there were significant two-way effects. Transportation, urban factors, and tourism resources all had consistent, predominantly positive, effects on the distribution of leisure agriculture.

Due to a lack of focus on China’s financial decentralization system, the existing research does not pay attention to the beneficial contribution of Chinese local governments to carbon emission reduction through their actions in the financial field. In this study, we collected 16 years of data from 30 provinces in China and utilized a two-way fixed-effects model to empirically test the impact of China’s financial decentralization on carbon emission reduction. The regression results show that China’s financial decentralization system has a significant carbon-emission reduction effect. A heterogeneity analysis shows that this effect is common in different regions of China and that fiscal decentralization will negatively moderate it. A mechanism analysis shows that under China’s financial decentralization system, the active intervention of local governments in local finance will significantly upgrade the energy consumption structure and ease the financing constraints of enterprises. The regression results of the spatial econometric model show that the carbon emission reduction effect of China’s financial decentralization still has a spatial spillover effect. Finally, we put forward corresponding policy recommendations.

In the collection of dust, vacuum cleaners are used to clean everything inside the car, including floor/carpet, seat, console, etc. To investigate the characteristics, possible sources and carcinogenic risks of polycyclic aromatic hydrocarbons (PAHs) contamination in car dust, fourteen car dust samples were collected from commercial car washes in Changchun, Northeast China. The 16 priority PAHs were all detected in 100%, and PAHs were predominantly tetracyclic. The mean ∑16PAHs content was 9297.79 ± 5855.89 ng g−1, ranging from 2940.03 to 23,174.51 ng g−1. Black carbon, total carbon and PAHs were weakly correlated. The results of positive matrix factorization indicated that coal combustion contributed 30.03% of PAHs and biomass combustion contributed 24.70%. Vehicle exhaust from traffic emissions, mainly incomplete combustion of gasoline and diesel, contributed 45.27% of PAHs. The mean incremental lifetime cancer risk (ILCR) values for children and adults were 4.94 × 10−3 and 4.37 × 10−3, respectively, both above the threshold value of 10−4. This indicates that PAHs from car dust put both adults and children at high carcinogenic risk, and that children are exposed to a higher carcinogenic risk than adults. This study provides a basis for proposing targeted measures to control PAHs’ contamination from car dust.
The Influence of High-Performance Work Systems on the Innovation Performance of Knowledge Workers

Published: November 2022

In the era of a knowledge economy, how to build an effective incentive system and to motivate the creativity of knowledge workers is extremely important to the long-term future of high-tech enterprises. However, a performance incentive system based on material incentives widely constructed by managers not only is difficult to generate in the long term and a significant incentive effect for knowledge workers but also brings heavy economic burden to enterprises. This paper constructs a high-performance work system (HPWS) that includes three variables: career growth, career calling and inclusive leadership. This study also discusses its effects on the innovation performance of knowledge workers, and examines the role of the craftsman spirit in the above-mentioned influence relationships. Based on the valid sample data of 364 knowledge workers from 14 different high-tech enterprises, the hierarchical regression analysis and the bootstrap analysis are used to analyze the data and to verify the relationship between the above-mentioned variables. The results show that: (1) Career growth, career calling and inclusive leadership can significantly improve the innovation performance of knowledge workers. (2) The craftsman spirit plays the part of an intermediary role in the above-mentioned influence relationships. (3) Career calling, inclusive leadership and their interaction can positively regulate the relationship between career growth and the craftsman spirit. Compared with previous studies, the purpose of this paper is to build a cross-level incentive system for knowledge workers from the perspective of non-material incentives, which effectively makes up for the deficiencies of material incentive system. Furthermore, the conclusion of this paper also provides practical suggestions for managers to better integrate the limited resources of enterprises to meet the multi-level needs of knowledge workers and to improve their innovation performance to the maximum extent.

This study aims to investigate the ways in which the linguistic landscape of a territory might be influenced by socio-political changes and movements to ensure social and cultural sustainability. To this end, this article reports on a study that examined the linguistic landscape of Doha after certain social and political changes since 2017. Further, this study aimed to examine how messages about power, unity sustainability, and national identity were communicated through the use of monolingual and bilingual signs in Doha. The article concludes that sudden socio-political changes can exert an influence on the linguistic landscape, and the linguistic landscape can be used as a tool for communicating messages about unity, sustainability, power and national identity. Moreover, the findings of this study suggest that the linguistic landscape can be used to maintain and improve social and cultural sustainability.

The aim was to review the effects of interventions based on self-determination theory and achievement goals theory on intention to be physically active in the future in physical education students, as well as to conduct a meta-analysis to determine the overall effect size of these interventions. PRISMA guidelines were followed to conduct this systematic review and meta-analysis. Three scientific electronic databases were used: Web of Science (WOS), Scopus, and SportDiscus. A total of eleven studies fulfilled the inclusion criteria and were included in the meta-analysis. Effect size for intention to be physically active of each study was calculated using the means and standard deviations before and after the intervention. The overall effect size for intention was moderate (standardized mean difference = 0.47 with 95% CI from 0.28 to 0.67), while the heterogeneity was large. Seven of the eleven studies reported significant within-group improvements in intention after the intervention. Eight studies showed significant between-group differences in favor of the experimental group. The findings showed that teaching strategies, family involvement, and the use of videos related to physical activity participation may be relevant factors that must be considered by educators and researchers to conduct future effective interventions. Interventions based on self-determination theory and achievement goals theory could be useful in the process of the promotion of physical activity. However, given the large heterogeneity, these findings must be taken with caution.
