BackgroundThe last decade has witnessed many achievements in China’s health care industry, but the industry still faces major challenges among which the uneven distribution of medical resources and the imbalance between supply and demand are the most pressing problems. Although mobile health (mHealth) services play a significant role in mitigating problems associated with health care delivery, their adoption rates have been low. ObjectiveThe objective of this study was to explore the impact of resource scarcity and resource accessibility on the adoption of mHealth from the perspective of resource competition, to examine the concerning factors, and to provide a theoretical basis for promoting mHealth in China. MethodsWe used 229,516 original registration records of outpatients to conduct an empirical analysis to examine the adoption of mHealth services from the perspective of resource competition. ResultsThe adoption rate of mobile services for outpatients was low, accounting for only 31.5% (N=71,707). The empirical results indicated that resource scarcity (beta=.435, P=.01) and accessibility (beta=−.134, P=.02) have a significant impact on the adoption of mHealth. In addition, gender (beta=.073, P=.01) and age (beta=−.009, P

Multimodal public transport network (MPTN) plays an important role in relieving road traffic pressure for metropolitan area. Nevertheless, the impact of an accident happened in an individual station may not only disrupt the station itself or the single lines that go through the station but also spread over the whole network. Therefore, identifying the vulnerable stations is essential for improving the MPTN management against the systematic risk caused by accidents. In this paper, we proposed a route diversity-based approach to measure the vulnerability of stations in MPTN based on the complex network theory. The route constraint parameters were established to reflect the travel time restriction in constructing the set of passengers' acceptable routes. In addition, an algorithm was formulated to rapidly calculate the route diversity index and meanwhile avoid the “overlapping routes” problem. A simple virtual network was used as a numerical example to compare the proposed approach with the vulnerability evaluation approaches based on degree centrality and betweenness centrality. Finally, the proposed approach was applied to the MPTN of Beijing to explain its effectiveness and potential applications. The results show that the proposed method can efficaciously estimate vulnerable nodes compared with degree centrality and betweenness centrality. Meanwhile, the acceptable routes between any OD pairs in the MPTN are 1-10 according to the constrained parameter. In addition, the average number of acceptable routes between OD pairs of Beijing MPTN is 3.649. By ranking the stations according to their vulnerability, it can be found that the top 5 vulnerable stations are all external traffic hubs or the stations around famous commercial areas. The results suggest that these stations are significant for external transport as well as crucial for internal urban transportation systems. The research output could contribute to the MPTN management in accident prevention and emergency handling., Author(s): Jianlin Jia (corresponding author) [1]; Yuwen Huang [1]; Wanting Zhang [1]; Yanyan Chen [2]; Zhuo Liu [2] 1.

Background The association between years of non-diabetes status after diagnosis of impaired glucose tolerance (IGT) and the risk of long-term death and cardiovascular outcomes needed to be clarified. Methods and findings In this post hoc analysis, we included 540 individuals with IGT who participated in the original Da Qing Diabetes Prevention Study (DQDPS). In the DQDPS, all participants were diagnosed with IGT by a 75 g oral glucose tolerance test and randomized to intervention or control groups with a 6-year lifestyle intervention trial. After the completion of the trial, death, cardiovascular events, and microvascular complications were monitored over a 30-year follow-up. In this post hoc analysis, the Cox analysis assessed the extended risk of these outcomes in individuals who either remained non-diabetes status or progressed to diabetes at the end of 2, 4, and 6 years after diagnosis of IGT. In all participants, the difference in the cumulative incidence rate of the outcomes between the diabetes and non-diabetes group gradually increased over 30 years. Compared with the diabetes group, a significantly lower risk of all-cause death (hazard ratio [HR]: 0.74; 95% confidence interval [CI]: 0.57 to 0.97, p = 0.026), cardiovascular events (HR: 0.63; 95% CI: 0.49 to 0.82, p < 0.001), and microvascular complications (HR: 0.62; 95% CI: 0.45 to 0.86, p = 0.004) first emerged in individuals who remained non-diabetes at the 4 years visit, whereas the significant risk reduction in cardiovascular death was first observed at the end of 6 years (HR: 0.56; 95% CI: 0.39 to 0.81, p = 0.002) after adjustment for age, sex, smoking status, BMI, systolic blood pressure, blood glucose, total cholesterol, intervention, and medications (including insulin plus oral hypoglycaemics, antihypertensives, and lipid-lowering agents). The results in the original intervention group alone were similar to the whole group. The main limitations of our study are the limited number of participants and the sole ethnicity of the Chinese population. Conclusions In this study, we observed that maintaining several years of non-diabetes status after IGT diagnosis was associated with a significant reduction in long-term risk of death and vascular complications, and for most of these outcomes, maintaining at least 4 years of non-diabetes status may be needed to achieve a significant risk reduction., Author(s): Xin Qian 1, Jinping Wang 2, Qiuhong Gong 1, Yali An 1, Xinxing Feng 1, Siyao He 1, Xiaoping Chen 3, Wenjuan Wang 4, Lihong Zhang 1, Yuanchi Hui [...]

Drivers' fault emergency response behavior can easily lead to crashes, resulting in significant economic and property losses. Exploring the causes of improper emergency response behavior is crucial for regulating driver behavior and preventing crash. Therefore, based on crashes data between commercial motor vehicles (CMVs) and noncommercial motor vehicles (NCMVs) that occurred in China from 2014 to 2018, this study established a binary logistic regression model. It systematically analyzed the key factors influencing drivers' fault emergency response behaviors in terms of individuals, vehicles, road conditions, environment, and corporate management. Additionally, it compared the differences in the influencing factors of fault emergency response behaviors between drivers of CMV and NCMV. The results indicate that the model fits well. The presence of faulty emergency response behavior in drivers is significantly correlated with five factors: age, gender, fatigue driving, speeding, and weather conditions. Moreover, these factors have different impacts on CMV drivers and NCMV drivers. Fatigue driving and speeding have a more significant impact on CMV drivers, while other factors are more pronounced for NCMV drivers. This study can provide valuable insights for the development of measures aimed at reducing the severity of CMV-NCMV crashes., Author(s): Panyi Wei [1,2,3,4]; Jianling Huang [5]; Yanyan Chen (corresponding author) [1,2]; Jianming Ma [6]; Yunchao Zhang [1,2]; Shaohua Wang [7]; Ning Chen [1,2] 1.

Negative interpersonal attitudes can affect people's well-being, interpersonal relationships, and cooperation. Overcoming negative interpersonal attitudes is a key subject in loving-kindness and compassion meditations (LCMs). However, the results and study design of previous research on negative interpersonal attitudes have been inconsistent. Therefore, it is necessary to summarize the effects of LCMs and explore moderators through meta-analysis. A literature search was conducted in the Cochrane Central Register of Controlled Trials, ISI Core Collection, Medline, ProQuest Dissertations & Theses, and PsycINFO databases up to April 2, 2021. Of the 281 identified empirical studies on LCMs, 25 measured negative interpersonal attitudes, and 21 were included in the meta-analysis. The results showed that the effects of LCMs on negative interpersonal attitudes in daily life were significant both for randomized controlled trials (g = -.203) and uncontrolled trials (g = -.539). The instant effects after meditation were also significant in randomized controlled experiments (g = -.187). Leave-one-out sensitivity analysis and nonsignificant subgroup analysis showed that the results were robust except for randomized controlled experiments. Although no significant moderators were identified, moderator analysis suggested that reducing bias and sending wishes to difficult targets were especially effective, and LCM subtypes might impact the results. Individual studies found that the contribution of meditation practice during interventions was weak. In sum, LCMs have the potential to reduce negative interpersonal attitudes, especially in multiweek interventions. Future studies should further explore the underlying mechanisms and consider the implications of study design features, such as the induction of negative interpersonal attitudes and the targets of LCMs., Author(s): Jingyi Zhou [sup.1] , Yongqi Lang [sup.1] , Zilin Wang [sup.1] , Chenyu Gao [sup.1] , Jing Lv [sup.2] , Yuan Zheng [sup.1] , Xiaodan Gu [sup.1] , Luyi [...]

Using students' assessments of teaching at a top university in China from 2016 to 2021, this study examines whether evaluation of teaching improves teaching quality. Given the many doubts about the validity of students' evaluation of teaching, this study adopts a methodology to distinguish teaching quality improvement from the reversal effect. It shows that instructors with a poor (good) ranking in the previous evaluation are more likely to receive an improved (decreased) ranking in the current evaluation. This reversal effect is more pronounced among the instructors who are associate/assistant professors, younger and female. This study provides evidence that supports the reversal effect rather than the improvement.
