The income gap between urban and rural households is a prevalent social issue in many countries, including China. This study examines the effect of information and communication technology (ICT) diffusion on the urban–rural income gap in China. We theoretically analyse how ICT infrastructure construction, financed by fiscal transfers, in rural areas narrows the rural–urban income gap. Further, our empirical results show that both ICT penetration at county level and ICT usage at household level narrow the rural–urban income gap. Moreover, compared to computer access, the newer generation of ICT devices (smartphones) has stronger effects in narrowing the rural–urban income gap. We find that smartphones play a key role in the reduction of this income gap by increasing the agricultural product operational income of rural households. [ABSTRACT FROM AUTHOR]

Background: The link between low grip strength, diminished physical performance, and adverse health outcomes in older adults has been well-established. However, the impact of older adults who cannot complete these tests on disability and mortality rates remains unexplored without longitudinal study. Methods: We collected data from the China Health and Retirement Longitudinal Study (CHARLS). Participants aged 60–101 were enrolled at baseline. We analyzed the prevalence of populations unable to complete handgrip strength (HGS), gait speed (GS), and five times chair stand test (FTCST). Completing risk models were used to estimate the risk of mortality and disability over seven years. Results: A total of 3,768 participants were included in the analysis. The percentage of older adults unable to complete the GS and FTCST tests increased notably with age, from 2.68 to 8.90% and 2.60–20.42%, respectively. The proportion of older people unable to perform the HGS was relatively stable, ranging from 1.40 to 3.66%. Compared to older adults who can complete these tests, those who cannot perform FTCST face a significantly higher risk of mortality, with 49.1% higher risk [hazard ratio (HR) = 1.491, 95% CI = 1.156, 1.922; subdistribution hazard ratio (SHR) = 1.491, 95%CI = 1.135,1.958)]. Participants who were unable to complete the GS test had a higher risk of developing ADL disability, regardless of whether they were compared to the lowest-performing group (HR = 1.411, 95%CI = 1.037,1.920; SHR = 1.356, 95%CI = 1.030,1.785) or those who can complete the GS (HR = 1.727, 95%CI = 1.302,2.292; SHR = 1.541, 95%CI = 1.196,1.986). No statistically significant difference in the risk of developing ADL disability among older adults who were unable to complete the HGS test compared with either the poorest performing group (HR = 0.982, 95% CI = 0.578, 1.666; SHR = 1.025, 95% CI = 0.639, 1.642) or those who were able to complete the HGS test (HR = 1.008, 95% CI = 0.601, 1.688; SHR = 0.981, 95% CI = 0.619, 1.553). The risk of all-cause mortality was not significantly different for older adults who were unable to complete the HGS test compared to those with the worst performance (HR = 1.196, 95%CI = 0.709–2.020; SHR = 1.196, 95%CI = 0.674, 2.124) or those who were able to complete the test (HR = 1.462, 95%CI = 0.872–2.450; SHR = 1.462, 95%CI = 0.821,2.605). Conclusion: The risks of adverse events faced by older adults unable to complete the tests vary, indicating the necessity for future research to conduct separate analyses on this high-risk population.

Identifying the sources of heavy metals (HMs) in river sediments is crucial to effectively mitigate sediment HM pollution and control its associated ecological risks in coal-mining areas. In this study, ecological risks resulting from different pollution sources were evaluated using an integrated method combining the positive matrix factorization (PMF) and the potential ecological risk index (RI) model. A total of 59 sediment samples were collected from the Kuye River and analyzed for eight HMs (Zn, Cr, Ni, Cu, Pb, As, Cd, and Hg). The obtained results showed that the sediment HM contents were higher than the corresponding soil background values in Shaanxi Province. The average sediment Hg content was 3.42 times higher than the corresponding background value. The PMF results indicated that HMs in the sediments were mainly derived from industrial, traffic, agricultural, and coal-mining sources. The RI values ranged from 26.15 to 483.70. Hg was the major contributor (75%) to the ecological risk in the vicinity of the Yanjiata Industrial Park. According to the PMF-based RI model, coal-mining activities exhibited the strongest impact on the river ecosystem (48.79%), followed, respectively, by traffic (34.41%), industrial (12.70%), and agricultural (4.10%) activities. These results indicated that the major anthropogenic sources contributing to the HM contents in the sediments are not necessarily those posing the greatest ecological risks. The proposed integrated approach in this study was useful in evaluating the ecological risks associated with different anthropogenic sources in the Kuye River, providing valuable suggestions for reducing sediment HM pollution and effectively protecting river ecosystems.

Objective: This study aims to explore the intervention effects of narrative nursing on the reproductive concerns of cervical cancer patients of childbearing age undergoing surgical treatment., Methods: Patients undergoing cervical cancer surgery with moderate to severe levels of reproductive concerns, treated between January and December 2023 at a tertiary Grade-A oncology hospital in China, were selected as the research subjects. Patients were randomized into an intervention group and a control group, each consisting of 33 patients. The control group received standard nursing care, while the intervention group received a narrative nursing intervention in addition to standard care. The changes in the levels of reproductive concerns, post-traumatic growth, and quality of life scores before and after the intervention were compared between the two groups., Results: After the intervention, the reproductive concerns scores of the cervical cancer patients in the intervention group (32.53 ± 4.77) were significantly lower than those in the control group (59.29 ± 3.24), with a statistically significant difference (t = 26.143, p < 0.001). The post-traumatic growth scores in the intervention group (86.78 ± 3.52) were significantly higher than those in the control group (68.06 ± 6.24), with a statistically significant difference (t = -14.595, p < 0.001). The quality of life scores in the intervention group (149.00 [IQR = 8.75]) were significantly higher than those in the control group (129.00 [IQR = 13.00]), with a statistically significant difference (z = -5.799, p < 0.001)., Conclusion: Narrative nursing can effectively alleviate reproductive concerns in cervical cancer patients undergoing surgical treatment, promote positive psychological changes post-trauma, and improve patients' quality of life., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.
