    Abstract The relationship between decentralization and inequality remains puzzling. The primary objective of this paper is to study the effects of decentralization on regional education inequality in China where national higher education policies systematically prioritize large cities. We apply the Gini coefficient and the econometric model of regional convergence (i.e., Barro regressions) to study original provincial college admission data in China from 2005 to 2013. We discover that the provincial Gini coefficients have been declining throughout the period. The Barro regression results also suggest that the provincial-level college-going rates have been converging. We further demonstrate that the convergence is driven by provincial rather than national universities. Access to elite national universities remained unequal across provinces and still favored super cities. We conclude that decentralization helps to drive down the regional inequality of access to higher education that is due to national polices. It is not yet clear whether our conclusion is applicable to other policy domains or other countries.

    Abstract Under the background of the digital economy, manufacturing seeks to improve green manufacturing and the level of greenness of products through digital empowerment. However, there exists a certain degree of technical difficulty and cost pressures for independent transformation to enhance green innovation performance through digitalization. How to conduct crossover cooperation with Internet enterprises needs to be explored. Taking automobile manufacturing enterprises as the case background, this paper constructs an evolutionary game model of green innovation crossover cooperation between traditional automobile manufacturing and Internet enterprises in the context of carbon credit policy. From the perspective of the extra effort cost of manufacturing enterprises and the excess income of Internet enterprises, this paper analyzes the mode selection strategy of green innovation crossover cooperation between the two types of subjects, and also analyzes the crossover cooperation mechanism of green innovation from three aspects: income distribution mechanism, carbon credit trading mechanism, and R&D subsidy mechanism. The results show that (1) Reducing the cost of digital green innovation transformation in manufacturing and the excess returns obtained under the free-riding behavior of Internet enterprises will help promote in-depth cooperation among crossover entities. (2) The benefit distribution dominated by manufacturing enterprises is helpful to evolve toward the direction of the alliance cooperative innovation mode and improve the benefits of green innovation cooperation. (3) Under the government’s single weak intervention management mechanism, optimizing carbon credit accounting and assessment standards can effectively guide manufacturers and Internet companies to conduct alliance green innovation cooperation, but they still need to be matched with appropriate R&D subsidies to form a compound strong intervention guidance mechanism to obtain higher social and ecological benefits.

    Abstract Under the background of digital economy and energy crisis, based on the theory of digital empowerment and prospect theory, aiming at the problems of inefficient collaborative innovation mode, long principal-agent chain, imperfect collaborative innovation mechanism and insufficient digital collaborative innovation degree of the core technology of new energy vehicles, this study constructs a decentralized multi-agent collaborative tripartite evolutionary game model with the participation of government building platform, new energy enterprises and academic research institutions, analyzes the evolution law and key factors, and finally compares the examples of the United States, China and European countries. Results show that: (1) Government subsidies should meet the sum of the strategic income difference and the credibility income is greater than the subsidies to enterprises and research institutions; (2) The subsidy structure and innovation performance show an inverted U-shaped structure. The management mechanism of platform should be optimized; (3) Government should improve the threshold for innovators to enter the decentralized new energy vehicle core technology breakthrough platform, and the contract maintenance strength is conducive; (4) The innovation subject has a dynamic income cost distribution coefficient, and reasonable control of the income and cost sharing coefficient is important; (5) Digital empowerment can make the above four mechanisms achieve dynamic optimization iteration and achieve better equilibrium solutions. Finally, practical countermeasures for the government are put forward, which improves the theoretical research and practical exploration.

    Abstract Abstract Most studies on the acceleration process of electric vehicle focus on reducing energy consumption, but do not consider the impact of the power battery discharge current and its change rate on the battery life. Therefore, this paper studied the interaction between electric vehicle energy consumption and power battery capacity attenuation during acceleration. First, a power battery life model for electric vehicle under driving conditions is established, and the percentage of battery capacity loss per kilometer is used to measure the capacity loss under different acceleration conditions. Then, the relationship between the percentage of battery capacity loss per kilometer and velocity and acceleration is explored, and the capacity attenuation mechanism of power battery under different acceleration processes is analyzed. Finally, the energy consumption and battery capacity attenuation is studied when the electric vehicle accelerated with multiple accelerations curves, and the interaction of the first acceleration and acceleration time on the electric vehicle energy consumption and the power battery capacity attenuation characteristics is discussed. The research results indicate that when the electric vehicle accelerates with different multiple accelerations curves, the change of energy consumption per kilometer and percentage of battery capacity loss per kilometer with acceleration and acceleration time is different, and the change of the two is basically opposite.

    Abstract This study aimed to investigate the axial compression performance of concrete-filled circular-end aluminum tube (RECFAT) columns, utilizing four specimens with varying parameters such as cross-sectional aspect ratio and cross-sectional aluminum content. Axial compression tests and ABAQUS finite element extended parameter analyses were conducted, with key mechanical performance indicators such as specimen failure morphology, ultimate bearing capacity, load–displacement curve, and load–strain curve being obtained. The influence of various variation parameters on the axial compression performance of the specimen was analyzed. The results indicated that the majority of specimens underwent oblique shear failure due to local bulging of the aluminum tube plane, while specimens with an aspect ratio of 4.0 experienced overall instability failure. As the aspect ratio increased, the bearing capacity improvement coefficient and ductility coefficient of the specimen decreased and the initial stiffness of the specimen gradually decreased. As the aluminum content increased, the initial stiffness decreased, with the critical aspect ratio for overall instability being between 2.0 and 2.5. The optimal aluminum content was recommended to be between 8.5% and 13.5%. When the aspect ratio was around 2.0, the lateral strain of the round-ended aluminum tube developed faster and the constraint effect was the best. The finite element model accurately reproduced the oblique shear bulging of the round-ended aluminum tube and the internal concrete V-shaped collapse, with the axial load–displacement curve being in good agreement. Improving the strength of aluminum alloy was more conducive to improving the axial compression bearing capacity of RECFAT than increasing the strength of concrete. A simplified model and calculation method for RECFAT was proposed, with an error of less than 1%.

    Abstract ObjectiveThis study examines whether the experience of unmet healthcare needs in a large sample of Chinese adults aged 60 and over is associated with adverse health outcomes, and how this association varied across needs related to health conditions.Study designThe 2013 wave of the China Health and Retirement Longitudinal Study is examined. We adopted latent class analysis to identify groups based on health conditions. Then in each identified group, we examined the extent to which unmet needs were associated with self-rated health and depression. To understand the channels through which unmet needs adversely affected health outcomes, we examined the impact of unmet needs attributed to various factors.ResultsCompared to the mean, experiencing unmet outpatient needs is associated with a 3.4% decrease in self-rated health, and people are twice as likely to have depression symptoms (OR = 2.06). Health problems are even more severe when inpatient needs are not met. The frailest people are most affected by affordability-related unmet needs, while healthy people are most affected by unmet needs attributable to availability.ConclusionTo tackle unmet needs, direct measures for particular populations will be required in the future.

    Abstract Objective: To systematically evaluate the efficacy of different training modes in patients with diabetes decline.
    Methods: PubMed, Cochrane Library, EMbase, Web of Science, CNKI, VIP, WANFANG, SinoMed were searched in computer to collect randomized controlled trials (RCTs) of training intervention in patients with diabetes and frailty, and the search time was as of May 21, 2023. After two review authors independently screened studies, extracted data, and assessed the risk of bias of included studies, network meta-analysis was performed using Stata14.0 and R4.3.1 software. Fasting blood glucose (FGB), glycosylated haemoglobin (HbA1c), two-hour postprandial blood glucose (PBG), total cholesterol (TCH), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), Short Physical Performance Battery (SPPB), and body mass index (BMI) were used as outcome measures.
    Results: A total of 15 RCTs were included, including 1550 patients. The results of the network meta-analysis showed that integrated training reduced FBG compared with the control group; integrated training, Pilates training, resistance training can reduce HbA1c; Pilates training and resistance training can reduce PBG; integrated training, Pilates training, resistance training can reduce TCH; Pilates training and resistance training can reduce TG; resistance training improves BMI. The results of the best probability ranking showed that multi-group training had the most significant effect on improving PBG and SPPB scores.
    Conclusion: The current evidence suggests that multi-group training is the best way to reduce fasting blood glucose and improve physical activity before meals, and Pilates training may be the best way to reduce glycated hemoglobin, blood glucose two hours after meals, improve blood lipid level and BMI in patients with diabetes in China.

    Abstract Aim: The aim of this review was to determine whether the caregivers of breast cancer patients who undergo psychosocial interventions report improvements in quality of life (QOL), depression, and anxiety. Methods: This systematic review was conducted in accordance with the PRISMA guidelines. A systematic search was conducted in the CINAHL, Embase, PsycINFO, PubMed, Web of Science, CNKI and Wanfang databases from inception until March 1, 2022. Randomized controlled trials (RCTs) and quasiexperimental studies involving psychosocial interventions for caregivers of breast cancer patients were included. Cochrane's risk of bias tool and the Joanna Briggs Institute checklist were used to assess the risk of bias. Results: This systematic review included eight original studies involving 528 caregivers of breast cancer patients. According to the meta-analyses, psychosocial interventions contributed significantly to improvements in QOL (SMD = 1.00, 95% CI [0.47, 1.54], p < 0.01), depression (SMD = −0.72, 95% CI [-1.02, −0.42], p < 0.01) and anxiety (SMD = −0.56, 95% CI [-0.86, −0.27], p < 0.01). Significant differences of psychosocial interventions on the QOL of caregivers were found in face-to-face and mixed-method psychosocial interventions (SMD = 0.97, 95% CI [0.19,1.75], p = 0.02; SMD = 1.45, 95% CI [0.86,2.05], p < 0.01) in the ≥3 months subgroup (SMD = 1.22, 95% CI [0.58,1.86], p < 0.01) but not in the spouses or partners subgroup (SMD = 0.83, 95% CI [-0.10,1.75], p = 0.08). Conclusions: This systematic review revealed that breast cancer patients' caregivers who undergo psychosocial interventions report improvements in QOL and reduced levels of depression and anxiety. It is worthwhile to use face-to-face methods when psychosocial interventions are conducted for caregivers. Future studies should examine long-term psychosocial interventions for spouses or partners of breast cancer patients. However, because of the limited number of original studies and the low quality of some included studies, the results ...

    Abstract An innovative soil solarization system based on biochar was recently proposed. The difference with traditional solarization lies in the use, after soil irrigation, of a biodegradable black liquid sprayed on the soil surface in order to obtain a black body capable of drastically increasing the absorption of incident radiation and, as a consequence, increasing temperatures at different depths. Due to these higher temperatures, it is possible to eliminate pathogens in shorter times than with traditional solarization. In recent years, this practice has been tested in various contexts by comparing traditional solarization with this innovative new practice through temperature measurement at different soil depths for two months. The experimental data confirm the validity of this new approach for soil treatment: higher temperatures were registered with the innovative system, up to 10 °C more than the traditional method. In this work, we report a comparison between the new solarization system and a fumigation method. Our experimental results demonstrate that it is possible to obtain a satisfying soil treatment with a natural and sustainable practice based on solar energy, overcoming the major limitation of traditional solarization: application time. The black layer on the soil allows for the attainment of temperatures as high as necessary to eliminate most pathogens in a shorter time (just 30 days) than traditional solarization (2 months).
