Investment volume in green projects, specifically in the green electricity market, suffers from limitations such as inadequate long-term financing, various risks, and a low rate of return on investment. Renewable energy power purchase agreements (PPAs), as a direct legal contract between a power provider and a power buyer, are one of the most popular instruments to increase investment. In this study, we model an adjusted PPA in the local currency framework to lower exchange rate risk and incremental tariffs by having the government pay part of the spillover tax revenues to the PPA, leading to a higher return on investment. The major conclusion of this study is that the use of tax revenue through the spillover effect of green electricity supply is a suitable source of financing for PPAs. As one policy implication, we recommend that developing countries allocate 50% of the tax revenue originating from power supply and adopt incremental PPAs to encourage private investment in green projects.

Energy transition as a major solution for climate change is debated among economists worldwide. This research contributes to the existing literature by investigating the impact of energy transition progress on power consumption in Asian countries. The models’ estimations are carried out by the system generalized method of moments (GMM) panel estimator for 35 Asian countries throughout 2000-2019. The major findings confirm that energy transition (migration from fossil fuels to renewable energy sources) positively impacts the electricity consumption of high- and upper-middle-income Asian countries. Furthermore, our results highlight that the sensitivity of electricity consumption in middle- and lower-middle-income Asian countries to inflation, electricity pricing, and population growth is higher than in high- and upper-middle-income Asian countries. The conclusion is that the electricity-energy transition nexus is highly sensitive to countries’ income levels and macroeconomic stability. This implies that Asian countries with different income levels need to first improve economic sustainability and resilience, followed by fossil fuel-to-green energy switch policies and technological efficiency in the power generation sector.

Osteoarthritis (OA), the most common degenerative joint disease, is associated with severe functional limitation and impairment of quality of life. Numerous reports have documented the clinical efficacy of low-dose radiotherapy (LD-RT) in the management of various inflammatory disorders, including OA. In this paper, we assessed the clinical literature involving the use of LD-RT in the treatment of OA, its dose-response features, possible underlying mechanistic features, and optimal therapeutic dose range. We carried out a systematic review based on the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statements and evaluated articles meeting the inclusion criteria for this review. A total of 361 articles were identified from databases, such as Scopus, PubMed, Embase, and Science Direct out of which 224 articles were duplicates and were discarded. Of the remaining 137 articles, 74 articles were un-related, 27 articles were review articles, eight were conference abstracts, three were letters, two were editorials, two were notes, and one was a book chapter. Finally, 20 articles met all the inclusion criteria and were included in this systematic review. Several single-arm retrospective/prospective studies showed advantages for LD-RT in the management of OA in terms of pain relief, improvement of mobility and function, and showed minimal side effects. Mechanistic considerations involve positive subcellular effects mediated by the activation of a nuclear factor erythroid 2-related transcription factor (Nrf2) mediated antioxidant response. Further research on both the short- and long-term effects of LD-RT on OA and other inflammatory disorders is recommended.

At present, China’s economy is in a crucial period of economic structural transformation. To alleviate the downward pressure on the economy and explore sustainable growth paths, the Chinese government has issued several environmental regulations. However, the impact of environmental regulation on industrial structure upgrading has not been carefully examined yet. This study utilizes the Pollution Information Transparency Index (PITI) to measure environmental regulation (ER) and examines the impact of ER on industrial structure upgrading (ISU). The sample cities are divided into 36 resource-based cities (RBCs) and 77 non–resource-based cities (NRBCs). The panel data containing 113 cities during 2008–2017 are used in this study. The empirical results show that ER has a significant impact on ISU of RBCs and NRBCs, and robust tests proved the reliability of this result. Analysis of heterogeneity shows ER has a more substantial role in promoting ISU in RBCs and the eastern region. Meanwhile, inside RBCs, ER has a more substantial impact on ISU in growth-RBCs than on that in other RBCs. The mechanism test shows that the mediation effect of technological innovation in RBCs and NRBCs is significant. At last, the impact of ER on ISU has a double-threshold effect in RBCs and a single-threshold effect in NRBCs. With the technological innovation progress, ER produces an increasing effect on ISU of RBCs and NRBCs.

This research presents the energy, exergy, economic, and environmental assessment, and multi-objective optimization of a flash-binary geothermal CCHP cycle. A sensitivity analysis of production well inlet temperature and cooling to power flow ratio on exergetic, economic, and environmental parameters was conducted. Furthermore, the effects of the inflation rate and plant working hours on economic parameters were investigated. Results showed that increasing the production well inlet temperature harms exergy efficiency and exergetic performance criteria and results in a gain in exergo-environmental impact index and heating capacity. In addition, the total plant cost increased by raising the production well temperature. Furthermore, increasing the cooling to power flow ratio caused a reduction in exergy efficiency, exergetic performance criteria, and produced net power and an enhancement in exergy destruction, cooling capacity, and total plant cost. The exergy efficiency and total cost rate in the base case were 58% and 0.1764, respectively. Optimization results showed that at the selected optimum point, exergy efficiency was 4.5% higher, and the total cost rate was 10.3% lower than the base case. Levelized cost of energy and the pay-back period at the optimum point was obtained as 6.22 c$/kWh, 3.43 years, which were 5.14% and 6.7% lower than the base case.

In the long history of the feudal society of China, Kaifeng played a vital role. During the Northern Song Dynasty, Kaifeng became a worldwide metropolis. The important reason was that the Grand Canal, which was excavated during the Sui Dynasty, became the main transportation artery for the political and military center of the north and the economic center of the south. Furthermore, Kaifeng was located at the center of the Grand Canal, which made it the capital of the later Northern Song Dynasty. The Northern Song Dynasty was called “the canal-centered era.” The development of the canal caused a series of major changes in the society of the Northern Song Dynasty that were different from the previous ones, which directly led to the transportation revolution, and in turn, promoted the commercial revolution and the urbanization of Kaifeng. The development of commerce contributed to the agricultural and money revolutions. After the Northern Song Dynasty, the political center moved to the south. During the Yuan Dynasty, the excavation of the Grand Canal made it so that water transport did not have to pass through the Central Plains. The relocation of the political center and the change in the canal route made Kaifeng lose the value of connecting the north and south, resulting in the long-time fall of the Bianhe River. Kaifeng, which had prospered for more than 100 years, declined gradually, and by the end of the Qing Dynasty, it became a common town in the Central Plains. In ancient China, the rise and fall of cities and regions were closely related to the canal, and the relationship between Kaifeng and the Grand Canal was typical. The history may provide some inspiration for the increasingly severe urban and regional sustainable development issues in contemporary times.

(1) Background: Because of the rapid expansion of the aging population in China, their health status transition and future medical expenditure have received increasing attention. This paper analyzes the health transition of the elderly and how their health transition impacts medical expenditures. At the same time, feasible policy suggestions are provided to respond to the rising medical expenditure and the demand for social care. (2) Methods: The data were obtained from the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2015 and analyzed using the Markov model and the Two-Part model (TPM) to forecast the size of the elderly population and their medical expenditures for the period 2020–2060. (3) Results: The study indicates that: (1) for the elderly with a mild disability, the probability of their health improvement is high; in contrast, for the elderly with a moderate or severe disability, their health deterioration is almost certain; (2) the frequency of the diagnosis and treatments of the elderly is closely related to their health status and medical expenditure; alternatively, as the health status deteriorates, the intensity of the elderly individuals’ acceptance of their diagnosis and treatment increases, and so does the medical expense; (3) the population of the elderly with mild and moderate disability demonstrates an inverted “U”-shape, which reaches a peak around 2048, whereas the elderly with severe disability show linear growth, being the target group for health care; (4) with the population increase of the elderly who have severe disability, the medical expenditure increases significantly and poses a huge threat to medical service supply. Conclusions: It is necessary to provide classified and targeted health care according to the health status of the elderly. In addition, improving the level of medical insurance, establishing a mechanism for sharing medical expenditure, and adjusting the basic demographic structure are all important policy choices.

The Indian electricity sector is at the cusp of transition. Facilitated by continuous policy thrusts, this transition, however, has not changed much on the ground as the growth of electric distribution utilities is still marred by conventional bottlenecks such as bad debts, shortage of funds, and a poor balance sheet. In this context, this study evaluated the efficiency of a selected set of 45 electricity distribution utilities in 21 states in India during the period 2018–19, using a two-stage analysis. First, an input-oriented data envelopment model with constant returns to scale was employed. Second, a regression analysis was performed to test whether efficiency scores influence such utilities’ financial viability, represented by the gap between average cost of supply and average revenue realized. The results indicated that there is a need to improve efficiency, as most of these utilities are technically inefficient. The analysis showed that a total cost-saving potential of around 2,387 billion Indian rupees could be achieved through efficiency improvements alone. Regression analysis highlighted that variables other than the efficiency of utilities such as aggregate technical and commercial loss and agricultural consumption as a percentage of total consumption contribute positively to utilities’ financial strength; hence, they should be prioritized by policymakers.

International remittances represent the most important source of external funding for developing countries. This chapter examines the impact of international remittances on poverty reduction, which is set as the first goal in the Sustainable Development Goals (SDGs) framework, using the panel data of 12 Asian developing countries. In terms of the dependent variables, this study picks up three poverty indicators: poverty headcount ratio, poverty gap ratio, and poverty severity ratio. The results show that international remittances have a statistically significant impact on reducing the poverty gap ratio and poverty severity ratio using the random-effect model of ordinary least squares (OLS) estimates. A 1% increase in international remittances as a percentage of GDP can lead to a 0.19% decline in the poverty headcount ratio, a 0.3% decline in the poverty gap ratio, and a 0.6% decline in the poverty severity ratio in sample 12 Asian developing countries from 1981 to 2018. Besides, the results indicate that trade openness can decrease poverty measures and that higher inflation rates may be one of the causes of poverty.

Background The current first-line treatment of locally advanced head and neck carcinoma (LAHNC) is concurrent chemoradiation with three-weekly cisplatin 100 mg/m2. However, prescribing cisplatin at this dose increases the treatment toxicity, which may compromise the treatment results. An alternative schedule is weekly 40 mg/m2 cisplatin. Aim To compare the acute hematologic and renal toxicities of these two regimens. Methods This randomized clinical trial included 77 LAHNC patients who were allocated to a high dose (100 mg/m2 every 3 weeks) or low dose (40 mg/m2 weekly) cisplatin group concurrent with radiotherapy. Hematologic and renal indices were measured weekly during chemoradiation. Results The average age of patients was 55.3 years. Overall, 71.4% of patients were treated in a definitive setting. The incidence of severe hematologic events was not significantly different. However, the average estimated glomerular filtration rate (eGFR) was significantly greater in the three-weekly group (67.85 vs. 58.57% mL/min per 1.73 m2; P-value = .02). Cumulative cisplatin dose of ≥240 mg/m2 was significantly greater in the weekly group. Totally, treatment breaks occurred in 40.3% of patients due to treatment toxicity. Treatment interruption was primarily due to neutropenia in the three-weekly and renal dysfunction and thrombocytopenia in the weekly group. Conclusions Severe acute hematologic toxicities were comparable for three-weekly and weekly groups. The decrease in eGFR through treatment was more significant with weekly cisplatin. Further follow-up, however, is needed to confirm its impact on delayed renal function.

The COVID-19 pandemic and the global recessions have reduced the investments in green projects globally that would endanger the achievement of the climate-related goals. Therefore, the post-COVID-19 world needs to adopt the green financial system by introducing new financial instruments. In this regard, green bonds—a type of debt instrument aiming to finance sustainable infrastructure projects—are growing in popularity. While the literature does not contest their effectiveness in fighting climate change, research highlights the high level of risks and low returns associated with this instrument. This study analyzes the green bond markets in different regions with a focus on Asia and the Pacific. It aims to fill the gap in the literature by conducting a comparative study of the characteristics, risks, and returns of green bonds based on the region. The study is based on theoretical background and empirical analysis using the data retrieved from Bloomberg New Energy Finance and the Climate Bonds Initiative. The empirical results are based on several econometrics tests using panel data analysis estimation methods, namely pooled ordinary least squares and generalized least squares random effects estimator. Our findings prove that green bonds in Asia tend to show higher returns but higher risks and higher heterogeneity. Generally, the Asian green bonds market is dominated by the banking sector, representing 60% of all issuance. Given that bonds issued by this sector tend to show lower returns than average, we recommend policies that could increase the rate of return of bonds issued by the banking sector through the use of tax spillover. In the era of post-COVID-19, diversification of issuers, with higher participation from the public sector and de-risking policies, could also be considered.

This study described an empirical link between COVID-19 fear and stock market volatility. Studying COVID-19 fear with stock market volatility is crucial for planning adequate portfolio diversification in international financial markets. The study used AR (1) – GARCH (1,1) to measure stock market volatility associated with the COVID-19 pandemic. Our findings suggest that COVID-19 fear is the ultimate cause driving public attention and stock market volatility. The results demonstrate that stock market performance and GDP growth decreased significantly through average increases during the pandemic. Further, with a 1% increase in COVID-19 cases, the stock return and GDP decreased by 0.8%, 0.56%, respectively. However, GDP growth demonstrated a slight movement with stock exchange. Moreover, public attention to the attitude of buying or selling was highly dependent on the COVID-19 pandemic reported cases index, death index, and global fear index. Consequently, investment in the gold market, rather than in the stock market, is recommended. The study also suggests policy implications for key stakeholders.

The Chinese government has stepped up its anti-corruption efforts since 2013; the National Energy Administration (NEA), an energy regulatory agency, has been hard hit by corruption. This paper analyzes the impact of government corruption on energy efficiency (EE) from a perspective of energy regulations and also a mechanism of the impact of corruption on EE, and then adopts statistical methods to estimate the impact of corruption on EE in China. The results show that government corruption generally has a negative effect on EE in China. The establishment of dispatched energy regulatory agencies in eastern China can significantly reduce the adverse effects of corruption on EE. Furthermore, a single threshold effect was found between corruption and EE. Finally, based on the results of an empirical analysis, suggestions for a constructive policy are put forward.

In water energy utilization, the damage of fault occurring in the power unit operational process to equipment directly affects the safety of the unit and efficiency of water power conversion and utilization, so fault diagnosis of water power unit equipment is especially important. This work combines a rough set and artificial neural network and uses it in fault diagnosis of hydraulic turbine conversion, puts forward rough set theory based on the tolerance relation and defines similarity relation between samples for the decision-making system whose attribute values are consecutive real numbers, and provides an attribute-reducing algorithm by making use of the condition that approximation classified quality will not change. The diagnostic rate of artificial neural networks based on a rough set is higher than that of the general three-layer back-propagation(BP) neural network, and the training time is also shortened. But, the network topology of an adaptive neural-fuzzy inference system is simpler than that of a neural network based on the rough set, the diagnostic accuracy is also higher, and the training time required under the same error condition is shorter. This algorithm processes consecutive failure data of the hydraulic turbine set, which has avoided data discretization, and this indicates that the algorithm is effective and reliable.

This study draws a comparison between the Global Financial Crisis (GFC) and the COVID-19 pandemic crisis to assess the safe-haven potential of Islamic stocks for G7 stock markets. We employ the cross-quantilogram framework of Han et al., which considers the non-linearity in the relationship, and thus captures the correlation between the Islamic and G7 stock markets across various quantiles reflecting different market conditions. The analysis also includes the time-varying cross-quantile correlation to observe the evolution of Islamic stocks' safe-haven potential. Our full sample analysis shows that Islamic stocks do not exhibit safe-haven properties for G7 stock markets. During the GFC period, Islamic stocks show some diversification benefits for the G7 stock markets. Notably, Islamic stocks emerged as a robust safe-haven asset for the G7 stock markets during the pandemic crisis. The study carries essential insights for equity investors and regulators of G7 and other countries to implement diversification/hedging strategies that would involve Islamic stocks to protect equity investments and the overall financial system amid the financial downturns.

Aim: To compare the acute radiation-induced bowel and bladder toxicities of two hypofractionated radiotherapy (HFRT) regimens in localised prostate cancer (PCa). Materials and methods: This trial consists of patients with histologically confirmed stage T1-T3aN0M0 PCa, a prostate-specific antigen concentration of 40 ng/mL or lower, and Eastern Cooperative Oncology Group performance status of 0–2. Participants were randomly assigned (1:1) to 56 Gy in 16 fractions over 4 weeks (arm A) or 70·2 Gy in 26 fractions over 5 weeks (arm B). Acute bowel and bladder toxicities were assessed using Radiation Therapy Oncology Group criteria. Results: Between June 2018 and December 2019, 40 patients were randomly assigned to treatment with 4-week (n = 20) and 5-week HFRT (n = 20). In the third month after completion of radiotherapy, the cumulative incidence of acute bowel and bladder toxicities of arms A and B was 20 versus 5% and 70 versus 85%, respectively. The cumulative incidence of grade 2 or worse bowel and bladder toxicities of the 5-week regimen was non-inferior to 4-week HFRT [bowel toxicity: 5% (arm A) versus 5% (arm B), bladder toxicity: 50% (arm A) versus 60% (arm B), p = 0·52). Findings: The 5-week regimen of HFRT is non-inferior to 4-week HFRT in terms of acute bowel and bladder toxicities.

Background: There is a global concern for the susceptibility of patients with cancer to the adverse effects of novel coronavirus disease (COVID-19). Nevertheless, there is a signal of potentially increased vulnerability of patients with cancer to more COVID-19-induced mortality, this notion needs to be further evaluated in various societies with different cancer epidemiology and practice. Objectives: To investigate the outcomes of cancer patients admitted due to COVID‐19 and compare them with data of COVID‐19 infected patients without a history of cancer. Methods: In this case-control study, the medical records of patients with cancer (Ca+ patients) who infected with COVID-19 were evaluated and compared with patients without a medical history of cancer (Ca- patients). Clinical data were collected from 19 February 2020 to 17 May 2020. The extracted data were classified into demographics, underlying medical conditions, clinical manifestations, imaging and laboratory findings, and clinical outcomes. Results: A total of 24 Ca+ patients were compared with 44 Ca- patients in terms of clinical manifestations and outcomes of COVID-19. The Ca- patients significantly developed more dry cough (75.0% vs 29.2%, P = 0.01) and fever (72.7% vs 45.8%, P = 0.02). Findings of the chest CT scan was comparable between groups, except for pleural effusion and lymphadenopathy that exclusively reported in Ca+ patients. (3% and 4%, respectively). At the end of observation, 13 (19.1%) patients died from COVID-19. This rate was significantly higher in Ca+ patients (41.7 vs 6.8%, P = 001). Likewise, Ca+ patients experienced more mechanical ventilation (25.0 vs 4.7%, P = 0.01). However, the rate of ICU admission was comparable between groups (P = 0.29). Conclusions: The patients with cancer had a higher rate of mechanical ventilation and COVID-19-induced mortality.

The current article extends the literature by proposing new models for estimating the classical and environmental performance of multi-plant firms. This yields some new indices for capturing the environmental performance vs. classical economic performance at the local and global level. The proposed approaches and indices were applied for the economic and environmental performance assessment of 46 power plants in Iran. The primary result emphasizes considering not only local environmental performance but also global performance to have a broad insight of environmental performance assessments. Moreover, we find only a few power plants with a resistant environmental performance at the global level. Proposed models in this article are general because they can be utilized in environmental analysis of any multiple plant production units.

Generally, public spending on education, research, and development (R&D) is perceived to impact the economy and sustainability positively; however, such notion lacks evidence, particularly in Belt and Road Initiative (BRI) member countries. In this study, panel data of BRI member countries from 2008 to 2018 is analysed using the generalized method of moments (GMM) method and data envelopement analysis (DEA) to assess the relationship between public spending on R&D and green economic growth and energy efficiency. The study found a fluctuating green economic growth indicator during the research period attributed to the non-serious nature of government policies. The findings reveal that the GMM method confirms both composition and technique effects in the entire sample. Nonetheless, the result of the sub-sample showed a heterogeneous effect on high GDP per capita countries. Moreover, the study shows that public spending on human resources and R&D of green energy technologies prompts a sustainable green economy through labour and technology-oriented production activities and different effects in different countries.

This paper examines the impact of environmental treaties on the environment across 74 countries: 50 resource-rich and 24 non-resource-rich countries. Using data spanning over 35 years, we find a negative and significant association between environmental treaties and environmental quality in resource-rich countries. On the contrary, we find environmental treaties positively and significantly affect the environment in non-resource-rich countries. Our results suggest that the environmental treaties signed by resource-rich countries may lead them to achieve sustainable development growth by 2030. Therefore, our results extend the environment literature and inform policymakers of the need to pay attention to the effects of signing environmental treaties on environmental protection.
