The coordinated development of rural infrastructure and ecological environment is an effective way to improve agricultural productivity. The primary focus of the current research is how the two can work together to promote regional economic development in rural areas and in related fields. This study takes the western region as the research object, constructs an evaluation index system for rural infrastructure and ecological environment, and uses the Min-max Scaling method, coupling coordination model, gray GM (1, 1) model, and standard deviation elliptical model for evaluation. The trends and driving factors for the coordinated development of rural infrastructure and ecological coupling in the region from 2012 to 2021 are analyzed. The main results are as follows: (1) Except for Tibet, Qinghai, and Ningxia, the coupling degree of rural infrastructure and the ecological environment in western China reached the maximum level during the research period, also the coordination degree showed a gradual upward trend. (2) A prediction for the development and evolution of rural infrastructure and the ecological environment in western China indicates a trend of agglomerative development in the southern region. (3) By strengthening the construction of reservoirs, improving sanitary conditions, improving cultivated land use area and forest coverage, and controlling soil erosion, the coordinated development of the two can be effectively promoted. The purpose of this study is to promote the sustainable and coordinated development of rural infrastructure and ecological environment, and to provide a reference for policy formulation in the relevant sectors and other countries and regions with similar situations.

Background: Burnout is prevalent among pediatric residents. Self-efficacy and resilience, as concepts of positive psychology, may be protective factors for burnout. However, no current data demonstrates the mechanism of their interaction. Objectives: To investigate the pediatric residents' status of self-efficacy, resilience, and job burnout in a university-affiliated hospital in western China. To explore relationships among them, especially the mediating effects of resilience. Methods: The study was conducted with 190 pediatric residents from an A-Class women's and children's hospital in western China. Data included demographic characteristics, status of pediatric residents, measures of burnout (using the Physicians' Career Burnout Questionnaire), self-efficacy (using the General Self-Efficacy Scale) and resilience (using the Connor-Davidson Resilience Scale). Multiple regression analysis and mediation analysis with bootstrapping were used to identify whether resilience mediates the relationship between self-efficacy and burnout. Results: Female pediatric residents exhibited significantly lower self-efficacy (t = 2.53, p<0.05) and higher levels of job burnout (t=-2.64, p<0.01) compared to male residents. Residents in the standardized training stage experienced higher levels of job burnout compared to those who had completed the training, as indicated by t-values of -3.21, -2.13, and − 2.80 (p<0.05). Significant correlations (p ≤ 0.01) were found among self-efficacy, resilience, and burnout. Additionally, our findings indicated that pediatric residents' self-efficacy can positively predict job burnout and its three dimensions through a major mediating effect of resilience. Conclusions: The findings regarding the mediating effect of resilience on the influence of self-efficacy on burnout, and their association with gender and residency status, have practical implications for interventions aimed at reducing burnout and improving the well-being of pediatric residents.

There is little available attenuation relationship for Arias Intensity (AI) in China. Empirical relationships between AI and peak ground acceleration (PGA) provide another option for predicting AI. We establish empirical relationships for AI and PGA for western China, utilizing 3,169 horizontal and 979 vertical strong motion records with PGA >0.01 g from 274 earthquakes (M[sub S] 4.0-8.0), originating in eight provinces in southwest (Yunnan, Sichuan) and northwest China (Gansu, Shaanxi, Ningxia, Qinghai, Inner Mongolia, and Xinjiang). The influences of M[sub S] epicenter distance, and site conditions indicators V[sub S30], generic site classes (i.e., rock and soil) are explored. The results show that the logarithm of AI increases linearly with the increase of the logarithm of PGA and M[sub S], and decreases with the logarithm of V[sub S30]. However, the influence of site conditions on AI-PAG relationships can't be recognized by the simple generic rock and soil site classes. The epicenter distance has little effect on the AI-PAG relationships. Empirical relationships are developed to estimate horizontal or vertical AI as a function of PGA (basic model), PGA and M[sub S] (model 2) for southwest, northwest, and western China, using all the records. Empirical relationships for AI as a function of PGA, M[sub S], and V[sub S30] (model 1) are established using the 2,248 horizontal (70.9% of the total) and 670 vertical (68.4% of the total) records with V[sub S30] between 148 and 841m/s. The notable disparity between model 1 of the southwest and northwest regions is chiefly attributed to local site conditions, indicating that the AI-PGA correlation is region-dependent. These findings enable one way of estimating AI for western China and will contribute to a better understanding of AI attenuation. [ABSTRACT FROM AUTHOR]

Currently, China has entered the development stage of a "low birth rate" demographically. There is a huge contradiction between the unbalanced and inadequate distribution of preschool education facilities (PEFs) and the people's expectations for "full and good education for children". This study took the Lingui New District, a typical new urban area in West China as the research area, and through the introduction of POI big data and GIS analysis methods, supplemented by GeoDA Bivariate Moran index analyses, established a kindergarten spatial database. The study found that preschool education facilities have problems such as insufficient quantity, uneven quality, low service coverage, poor accessibility, etc. Therefore, it is suggested to increase the proportion of public affordable preschool education facilities including kindergartens and nurseries, optimize the spatial distribution of preschool education, and improve the accessibility of preschool services to promote affordable, safe, and high-quality development of preschool education and to provide reference suggestions for the revision of relevant standards and the adjustment of the layout of preschool education in undeveloped regions of China.

Food, water, and energy (FWE) are foundational resources that sustain human well-being and societal advancement. The examination of climate change effects on FWE resources is imperative, particularly in regions abundant in natural resources but ecologically fragile. In this context, we investigated the spatiotemporal changes of FWE resources in China's western frontiers, where both resource wealth and climate vulnerability are critical. This study proposes an innovative approach to comprehensively analyze the dynamics of food production, surface water, and solar energy from 2010 to 2021 by integrating easily accessible and widely applicable variables, and utilizing remote sensing and statistical data within a sustainable development framework. The results show that: (1) both crop yield and cropland area display an upward trend; (2) the expansion of overall surface water area in Xinjiang is mainly driven by changes in precipitation and temperature, while in Xizang, such a relationship is not evident; (3) Xinjiang and Xizang have advantages in solar photovoltaic (PV) development due to their abundant solar resources. Our results suggest that such spatiotemporal dynamics in food production, surface water and solar energy resources can intuitively reflect the sustainable development status of FWE resources in China's western frontiers.
