In recent years, many models based on the convolutional neural network have achieved highquality reconstruction for single image super-resolution. Meanwhile, many researches on image superresolution have been applied to various fields. However, only a few research works have been applied to climate prediction. In this paper, we present ResLap to achieve high-resolution climate prediction. ResLap is a spatial downscaling method that converts low spatial resolution climate data into high-resolution regional climate forecasts. This method mainly introduces a novel residual dense block (RDB) into the Laplacian pyramid super-resolution network (LapSRN). Among them, we use LapSRN to achieve upsampling image reconstruction, and adopt RDB to fully extract the hierarchical features from all the convolutional layers. Extensive experimental results on benchmark climate datasets show that our new proposed model performs better than many super-resolution methods. Besides, the climate data are more complicated than the general image, because of its dynamic and chaotic nature. To facilitate model training, we integrate original climate data provided by the China Meteorological Administration, then convert it into trainable climate images. We also publish some climate image datasets online for research. Finally, we avoid the checkerboard artifacts in the generated high-resolution climate images. INDEX TERMS Super-resolution, climate image, checkerboard artifacts, convolutional neural network.

Long-term care insurance (LTCI) is garnering attention internationally and is being considered a public policy in a growing number of countries. Previous research has focused on the effects of LTCI in developed countries, ignoring the health outcomes of developing countries, especially in rural regions. Therefore, this study investigates whether different impact on health outcomes is present in the effects of LTCI between urban and rural residents in China. We employed a quasi-experimental design with data from the China Health and Retirement Longitudinal Survey. The specific implementation time of each pilot city was sorted according to the LTCI policy texts, dividing these pilot cities into the treatment group and control group. Finally, difference-in-differences analyses were utilized to evaluate the health effects of LTCI between urban and rural residents, and the health effect in urban areas was further tested. The implementation of LTCI has effectively enhanced the self-rating health (SRH) of the entire group of residents; however, this effect may only be significant for the urban group. In particular, LTCI can increase the SRH of urban residents by 0.377 units compared to the urban residents without LTCI (P < 0.01). The result of the placebo effect test further verifies that LTCI could improve the health of residents to some extent. In China, LTCI may have triggered different impacts on health outcomes between urban and rural residents, and may not improve the SRH of rural residents and only prove efficacious for urban residents. Government and policy-makers should give more attention to the rural group as it needs long-term care the most.

A well-designed institutional arrangement for urban village redevelopment projects (UVRPs) must consider transaction costs, but academic papers discussing it from the perspective of transaction cost economics are lacking. This paper applies theory of transaction cost economics to analyse the types and sizes of transaction costs and who bears these costs during redevelopment when implementing UVRPs in China. This paper finds that transactions in UVRPs have high asset specificity, high uncertainty and low frequency, which easily results in high levels of transaction costs. Based on 439 UVRPs collected from seven cities, this paper finds that UVRPs implemented with top–down institutional arrangements remain prevalent in China. Based on semi-structured interviews with participating parties, this paper proves that the sizes and types of transaction costs and the distribution of these costs borne by different participating parties vary with the change of stage under dissimilar institutional arrangements. This implies that a high level of transaction costs at one stage does not necessarily mean the costs stay high at another stage. Transaction costs have essential implications for process efficiency, so policymakers need to consider transaction costs and use hybrid institutional arrangements to enhance the efficiency and sustainability of policies.

BackgroundDespite growing evidence focusing on health inequalities in older adults, inequalities in medical compensation compared with younger adults and gender disparities of medical errors among older patients have received little attention. This study aimed to disclose the aforementioned inequalities and examine the disparities in medical errors among older patients.MethodsFirst, available litigation documents were searched on “China Judgment Online” using keywords including medical errors. Second, we compiled a database with 5,072 disputes. After using systematic random sampling to retain half of the data, we removed 549 unrelated cases. According to the age, we identified 424 and 1,563 cases related to older and younger patients, respectively. Then, we hired two frontline physicians to review the documents and independently judge the medical errors and specialties involved. A third physician further considered the divergent results. Finally, we compared the medical compensation between older and younger groups and medical errors and specialties among older patients.ResultsOlder patients experienced different medical errors in divergent specialties. The medical error rate of male older patients was over 4% higher than that of females in the departments of general surgery and emergency. Female older patients were prone to adverse events in respiratory medicine departments and primary care institutes. The incidence of insufficient implementation of consent obligation among male older patients was 5.18% higher than that of females. However, females were more likely to suffer adverse events at the stages of diagnosis, therapy, and surgical operation. The total amount of medical compensation obtained by younger patients was 41.47% higher than that of older patients.ConclusionsExcept for the common medical errors and departments involved, additional attention should be paid to older patients of different genders according to the incidence of medical errors. Setting up the department of geriatrics or specialist hospitals is also an important alternative to improve patient safety for older people. Furthermore, there may be inequality in medical compensation in older patients due to the tort liability law of China.
