The ability of using internally generated funds to finance investments affects corporate sustainability. We empirically examine trends and gaps in the reliance of company’s investments on internally generated funds. We collect financial data of Chinese listed companies from 1998 to 2020, use corporate cash flow as a proxy for internally generated funds, control for corporate investment opportunity Q, and specify a two-way fixed effects model of investment on cash flow. We find that investment-cash flow sensitivity exhibits a decreasing trend over time; firm size, government equity, and the HP and WW indices effectively explain the gaps in the sensitivity of investment to cash flow between two types of firms with tighter and looser financing constraints, but cash dividends do not explain the gaps; and the gaps in the sensitivity of investment to cash flow are narrowing in the long term. These empirical findings indicate that compared to external funding, internal funding is becoming less important in supporting a firm’s investment-induced sustainability. Full article

Conventional tillage (CT)-based agriculture is known to be ecologically indiscreet, economically and environmentally unsustainable, and leads to the degradation of soil and the environment in the Indo-Gangetic Plain (IGP). The surface seeding (SS) method was introduced to manage agro-ecosystems for sustaining productivity and increasing farmers’ profits, while sustaining the natural resources. Here, we conducted a systematic literature review on SS of wheat reported in the IGP, with the aim to cover the concept of SS, its impact on wheat yield, soil properties, and the environment, with the potential benefits and constraints. The major findings are: (i) an SS-based rice–wheat system improves productivity (∼10%) and profitability (20–30%),while employing a lesser amount of irrigation water (15–30%) and energy input (20–25%) compared to a conventional system; (ii) an SS-based system is more adaptive to extreme climatic conditions, reduces the carbon footprint, and increases crop production; (iii) an SS approach enhances soil health by virtue of increased soil organic carbon and improved soil aggregation, as well as soil, water, and energy conservation; (iv) SS consisting of no-tillage with substantial crop residue retention offers an alternative to crop residue burning. Strong policies/legislation are required to encourage SS of wheat, in order to limit residue burning, and provide farmers with carbon credits in exchange for carbon sequestration and reduced greenhouse gas emissions.

The success of major events can enhance national image, boost people’s confidence, and alleviate the current “three-fold pressure”—contraction in demand, supply shocks and weak expectations. In the context of the carbon neutrality target, it is important to analyze the relationship between major events and carbon emissions as the ecological, social and economic systems become more closely related. To study the extent and persistence of the impact of major events on the carbon emissions of the hosting provinces, this paper collects annual carbon emission data from 2015 to 2019 for 30 provinces in China. The propensity score matching Difference in Difference model (PSM-DID) is used to explore the impact of major events, such as political conferences, sports events and cultural exchanges, at the national level on inter-provincial carbon emissions. The empirical study shows that (1) the carbon emissions of the provinces involved in major events significantly increase in the year when the major event is held, (2) the carbon emissions of the province significantly decrease in the year after the conclusion of the major event, and (3) the decrease is higher than the increase in carbon emissions in the year when the event is held. Finally, the model results are analyzed in the context of economic events and macroeconomic policy lags during the preparation period of the event, and policy suggestions are made to incorporate carbon neutrality into the overall layout study of ecological civilization construction, strengthening the construction of legal thinking, enhancing inter-provincial and inter-city pollution synergy control, innovating carbon-related technologies, unifying carbon emission accounting and improving data openness.

In construction industry, phase change materials (PCMs), have recently been studied and found effective in increasing energy efficiency of buildings through their high capacity to store thermal energy. In this study, a combination of Capric (CA)-Palmitic acid (PA) with optimum mass ratio of 85–15% is used and impregnated with recycled concrete powder (RCP). The resulting composite is produced as foam concrete and tested for a series of physico-mechanical, thermal and microstructural properties. The results show that recycled concrete powder can host PCMs without leaking if used in proper quantity. Further, the differential scanning calorimetry (DSC) results show that the produced RCP/CA-PA composites have a latent heat capacity of 34.1 and 33.5 J/g in liquid and solid phases, respectively, which is found to remain stable even after 300 phase changing cycles. In this regard, the indoor temperature performance of the rooms supplied with composite foams made with PCMs, showed significantly enhanced efficiency. In addition, it is shown that inclusion of PCMs in foam concrete can significantly reduce porosity and pore connectivity, resulting in enhanced mechanical properties. The results are found promising and point to the suitability of using RCP-impregnated PCMs in foam composites to enhance thermo-regulative performance of buildings. On this basis, the use of PCMs for enhanced thermal properties of buildings are recommended, especially to be used in conjunction with foam concrete. Full article

During the COVID-19 pandemic, digital capital and online activities have played significant roles as a tool for enhancing social support. Considering the increased role of information communication technology (ICT), in this study, we investigated the following research questions by focusing on the Indonesian Muslim diaspora in South Korea. To what extent do digital capital and online communities affect the formation of social support in the pandemic situation? How does the Indonesian Muslim diaspora pursue social support in South Korea, which has a high capacity for ICT infrastructure? We used the technology acceptance model (TAM) for the conceptual model and conducted semi-structured interviews and surveys for data collection. Structural equation modeling demonstrates that TAM can be applied in the case of South Korea’s Indonesian Muslim diaspora, especially during the pandemic. Findings suggest that digital capital and the perceived usefulness/perceived ease of use (PU/PEOU) of online communities reinforced the Indonesian Muslim diaspora’s participation in online communities after COVID-19. It also demonstrates the ways in which the Indonesian Muslim diaspora pursues social support through online communities under restricted situations. Full article

In this study, a seismic isolator placed on the base of a structure was optimized under various earthquake records using an adaptive harmony search algorithm (AHS). As known, the base-isolation systems with very low stiffness provide a rigid response of superstructure, so it was assumed that the structure is rigid and the base-isolated structure can be considered as a single-degree of freedom structure. By using this assumption, an optimization method that is independent of structural properties but specific to the chosen earthquake excitation set is proposed. By taking three different damping ratio limits and isolator displacement limits, the isolator period and damping ratio were optimized so that the acceleration of the structure was minimized for nine cases. In the critical seismic analysis performed with optimum isolator parameters, the results obtained for different damping ratios and isolator periods were compared. From the results, it is determined that isolators with low damping ratios require more ductility, and as the damping ratio increases, further restriction of the movement of the isolator increases the control efficiency. Thus, it is revealed that increasing the ductility of the isolator is effective in reducing the total acceleration in the structure. Full article

Changing and reconstructing the ecological space of urban agglomerations is inevitable for ecological conservation and a scientific problem that needs urgent attention from geography, ecology, and urban and rural planning. Using ArcGIS and other software for data processing, this study established a spatial attribute database, constructed a land use conversion matrix of the Changsha-Zhuzhou-Xiangtan (CZX) urban agglomeration’s ecological space, and quantitatively analyzed the main changes in ecological land. Using a trained cellular automata model with predicted land use in 2035 as the threshold value, the simulation research was presented by creating two simulation scenarios for the spatial distribution of land use by 2035 in the “Green Heart” area of the CZX urban agglomeration. The simulation results were compared, and the constraining role of land use suitability evaluation on ecological space evolution was analyzed. This study found that the total area of ecological space in the Green Heart area saw a rapid reduction, and it predicted that, by 2035, the total area of the CZX Green Heart area will have decreased. Comparing the two simulation scenarios proved the hypothesis that zoning ecological space reconstruction based on a land suitability evaluation can effectively protect ecological space and ensure ecological network functions are harnessed.

Wheat yellow rust (YR) caused by Puccinia striiformis is lethal for the leaf photosynthetic process, which substantially affects yield components and ultimately causes drastic yield reduction. The current study aimed to identify all-stage YR resistance linked QTLs in the best cross-combination. Experimental materials were phenotyped for disease severity in YR-hot spot area at Cereal Crops Research Institute, Pirsabak Pakistan in Khyber Pakhtunkhwa province in 2019 and 2020 and 2020 and 2021 Rabi seasons. The AN179 × KS17 was found to be the best cross combination, which showed high resistance to YR, whereas crosses AN179 × PK15 and PR129 × PK15 demonstrated susceptibility to YR with high disease severity. The recombinant inbred lines (RIL) F₂ wheat population Annong-179/Khaista-17 demonstrated highly desirable YR resistance and yield component traits. Simple sequence repeat (SSR) markers were used to genotype the RIL population and their parents. Three novel QTLs linked to all-stage YR resistance were found on chromosomes 2BS, 3BS and 6BS, which explained 1.24, 0.54, and 0.75 phenotypic variance, respectively. Incorporation of the newly identified novel YR-resistance associated QTLs into hybridization wheat breeding program could be effective for marker-assisted selection of the improved and sustainable resistance.

Water environment monitoring is an important way to optimize the allocation and sustainable utilization of regional water resources and is beneficial for ensuring the security of regional water resources. In order to explore hydrochemical distributions in a mountain–oasis ecosystem in Central Asia, surface water and groundwater samples from the Kaidu River basin were collected over four seasons. pH values, major ions, total dissolved solids (TDS) and stable isotopes were determined during the period from 2016 to 2017. The results showed: (1) that most water bodies in the study areas were mildly alkaline and that hydrochemical distributions showed significant seasonal and spatial variation; (2) that δD and δ¹⁸O in surface water and groundwater showed enrichment in summer and autumn and poverty in spring and winter, with higher δ¹⁸O values appearing in the oasis area and lower δ¹⁸O values appearing in the mountain area; (3) that most of the water bodies in the study areas were of HCO₃⁻Ca²⁺ type, with the hydrochemical types of groundwater presenting obvious spatial inconsistency relative to surface water; (4) that rock weathering was the main factor controlling hydrochemical composition in the study areas and that human activities had an influence on the groundwater environment in the oasis area; (5) and that surface water–groundwater interactions also displayed spatial inconsistency, especially in summer. The interaction between river water and groundwater was more obvious in the traditional oasis area, especially in spring and summer. The results will be important for regional water resource management and sustainable water utilization. Full article

Creativity, ideas, and an entrepreneurial attitude are needed to innovate. However, it is also necessary to have practical instruments that allow innovations to be reflected in the company. One of those tools is technology. This research aims to analyze innovation and technology in the tequila industry through Bayesian networks with machine learning techniques. Likewise, an innovation and technology management model will be developed to make better decisions, which will allow the company to innovate to generate competitive advantages in a mature low-tech industry. A model is made in which the critical factors that influence management innovation and technology optimally to generate value translate into competitive advantages. The evidence shows that the optimal or non-optimal management of knowledge management and its various factors, through the causality of the variables, allow the interrelation to be more adequately captured to manage it. The results show that the most relevant factors for adequate management of innovation and technology are knowledge management, sales and marketing, organizational and technological architecture, national and international markets, cultivation of raw materials, agave, and management, use of waste, and not research and development.

The potential of composts produced from different origin residues to be used in environmentally friendly agriculture is addressed in this work. Seven composts obtained from different raw materials and composting methodologies are compared using elemental, thermal and spectroscopic characterization data. Despite the stabilization of the organic matter in all composts being adequate for agricultural applications, they display distinct elemental and structural compositions. Likewise, the fertilisers have very different effects on lettuce growth. Despite the observed differences, some common features were found, namely a mass loss (TGA) of 25.2 g per mol C, association between groups of elements (Fe, Al, Ni, Co, Cr, Cu and S; Mg, Na, K and P, C, C_oxi, N and Pb) and correlations between the amount of carbon nanostructures and the characteristic aromaticity parameters. These results suggest that the tuning of the compost features for specific cultures may be possible for sustainable food production. Full article

Cohesion policy is a constant and central area of interest across the European Union. The development and success of European society depends on the social and economic cohesion at the level of all member states. Starting from this assumption, our study will focus on the interdependence between social cohesion and social support, the latter being interpreted and analysed as a means whereby social cohesion may be achieved. Thus, understanding the manifestations of community cohesion at the level of the European communities is an essential element in this investigation, while its main purpose is to build an explanatory model for interpreting social support. Based on such a framework, social cohesion may be analysed and understood. The following measurement scales will be applied to the analysis of social support: the Multidimensional Scale of Perceived Social Support, the Survey of Recent Life Experiences, and the Satisfaction with Life Scale. The source of the information is a non-random sample of 1364 respondents. Data processing is based on the implementation of structural equation modelling (SEM) in order to explore the key factors that influence the perception of social support. As mentioned previously, we plan to build an explanatory model that links the perception of social support with life satisfaction and the disturbing factors that are the outcome of life experiences. A set of comparisons is also made using the independent t test and one-way ANOVA. The perception of social support is interpreted from the perspective of the occupational situation, the age category, the educational level and the marital status of respondents. The variables included in the study generally satisfied the goodness of fit indexes in accordance with the recommendations of the literature on SEM models. The conclusions of the study show that social support is at the core of community integration and one of the determinant elements of social cohesion. Everyday life events condition the perception of social support. In turn, the perception of social support acts on life satisfaction. It has been observed that a higher perception of social support may be associated with greater cohesion at the level of communities and also with a more stable social environment. We have identified a determining relationship between the perceived social support and the degree of social cohesion. Full article

Tens of thousands of Vietnamese workers have entered the agriculture, forestry, foreign trade, and manufacturing industries in rural Chongzuo of the Guangxi autonomous region. However, over 70% of these cross-border Vietnamese workers resign at least once a month. This study applies a survival analysis on the registration data of cross-border Vietnamese workers in 2019 to investigate the main drives of high job turnover. A Kaplan–Meier plot shows that the 30-day valid period of work permits is an important source of the frequent resignation of Vietnamese workers. A Cox regression analysis presents that Vietnamese laborers working in manufacturing, working in the sugarcane industry, or from the seven Vietnam provinces closest to Chongzuo have lower risks of turnover. This study implies that Chongzuo should bring in more manufacturing enterprises, expand work permit valid periods, and offer migrant workers vocational training. Full article
