Evaluation of road network resilience under a volcanic debris flow disaster at Changbaishan Mountain based on inundation simulations
Expedited Approval of Urgently Needed Drugs in China
This cross-sectional study evaluates the approval status and timeline and therapeutic value of urgently needed overseas drugs in China
Women as ‘space invaders’ in a gendered billiards hall
This article takes inspiration from feminist sociologist Nirmal Puwar’s conception of ‘space invaders’, to examine the gendered dynamics within a billiards hall in suburban Shanghai. Drawing upon insights obtained via participant observations in the hall and interviews conducted with members of the college billiards society affiliated with the hall, the article not only identifies the nuanced forms of sexism operating within/through the billiards…
Geological Hazard Assessment of Secondary Collapses Due to Volcanic Earthquakes on Changbai Mountain in China
In recent years, the volcanic activity of Changbai Mountain has been accompanied by several earthquakes, and the frequent human engineering activities have led to a gradual increase in the number of collapses in the region, which severely impacts residents’ lives and property safety. In northeastern China, the Changbai Mountain area in the southeastern Jilin Province is a typical mountain environment. This paper selects 12 evaluation indicators t…
Application of AHP-ICM and AHP-EWM in Collapse Disaster Risk Mapping in Huinan County
Collapses are one of the most common geological disasters in mountainous areas, which easily damage buildings and infrastructures and bring huge property losses to people’s production and life. This paper uses Huinan County as the study area, and with the help of a geographic information system (GIS) based on the formation principle of natural disaster risk, the information content method (ICM), the analytical hierarchy process (AHP), and the ana…
Risk Assessment of Landslide Collapse Disasters along National Highways Based on Information Quantity and Random Forest Coupling Methods
Based on the data from two field surveys in 2015 and 2022, this paper calculates the weight of values using the entropy weight method and the variation coefficient method, and evaluates risk using the information quantity method. The information quantities of four levels of criteria (hazards, exposure, vulnerability, emergency responses, and capability of recovery) were extracted and inputted into a random forest model. After optimizing the hyper…
The impact of government reimbursement negotiation on targeted anticancer medicines use and cost in China
Background: High prices of targeted anticancer medicines (TAMs) result in financial toxicity for patients and the health insurance system. How national price negotiation and reimbursement policy affect the accessibility of TAMs for cancer patients remains unknown. Methods: In this population-based cohort study, we used national health insurance claims data in 2017 and identified adult patients with cancer diagnoses for which price-negotiated TAMs…
Constructing Student Mobility
Review of: Constructing Student Mobility: How Universities Recruit Students and Shape Pathways between Berkeley and Seoul , Stephanie K. Kim (2023) Cambridge, MA: MIT Press, 212 pp., ISBN 978-0-26254-514-3, p/bk, $40
Analysis of Influencing Factors of Psychological Intervention on International Students in China after Covid-19
Objectives: In the post-covid-19 era, students face numerous mental health-related effects. Returning to Chinese institutions, international students in China experienced mental health issues (anxiety and stress). These overseas students' psychological issues are obstacles to their academic performance in China. Students' fear restructured their ability to think critically and execute effectively. Consequently, the framework of this study is inte…
The impacts of government reimbursement negotiation on targeted anticancer medication price, volume and spending in China
INTRODUCTION: New targeted therapies have changed cancer treatment in the past decades. However, high prices of targeted anticancer medications have increased economic burden for both patients and health insurance systems. In July 2017, China implemented combined medication price negotiation and mandatory reimbursement policies for 15 targeted anticancer medications. This study assesses effects of the policy on hospital procurement prices, volume…
Risk Assessment of An Earthquake-Collapse-Landslide Disaster Chain by Bayesian Network and Newmark Models
Severe natural disasters and related secondary disasters are a huge menace to society. Currently, it is difficult to identify risk formation mechanisms and quantitatively evaluate the risks associated with disaster chains; thus, there is a need to further develop relevant risk assessment methods. In this research, we propose an earthquake disaster chain risk evaluation method that couples Bayesian network and Newmark models that are based on natu…
Environmental Risk Assessment of Metals in the Volcanic Soil of Changbai Mountain
Tianchi volcano is a dormant active volcano with a risk of re-eruption. Volcanic soil and volcanic ash samples were collected around the volcano and the concentrations of 21 metals (major and trace elements) were determined. The spatial distribution of the metals was obtained by inverse distance weight (IDW) interpolation. The metals' sources were identified and their pollution levels were assessed to determine their potential ecological and huma…
