Many local governments provide subsidies to promote electric vehicles (EVs). These subsidies are characterised by different implementation patterns: they are provided by different levels of government, sometimes jointly financed, or retroactively implemented. However, the potential impacts of different subsidy implementation patterns on EV adoption remain unclear. In this study, we analyse the impact of local subsidy implementation patterns on EV adoption. We first propose an analytical model and then verify it empirically using monthly panel data on EV adoption in 132 Chinese cities. We find that municipal subsidies are more effective than both provincial and jointly financed subsidies in promoting EV adoption. Each 10% increase in municipal subsidies (as a share of national subsidies) can promote approximately 1000 more EVs than corresponding provincial subsidies and approximately 965 more EVs than jointly financed subsidies. Retroactive subsidies do not significantly hinder local EV adoption. Our research provides valuable empirical evidence for policymakers to steer toward more synergistic EV adoption policies.

Background: Having a great amount of sedentary time is common among older adults and increases with age. There is a strong need for tools to reduce sedentary time and promote adherence to reduced sedentary time, for which eHealth interventions have the potential to be useful. Interventions for reducing sedentary time in older adults have been found to be more effective when elements of self-management are included.

Division of Psychology and Mental Health, University of Manchester, Manchester, United Kingdom.
Background: Digital mental health interventions (DMHIs) to monitor and improve the health of people with psychosis or bipolar disorder show promise; however, user engagement is variable, and integrated clinical use is low.
Objective: This prospectively registered systematic review examined barriers and facilitators of clinician and patient engagement with DMHIs, to inform implementation within real-world settings.
Methods: A systematic search of 7 databases identified empirical studies reporting qualitative or quantitative data about factors affecting staff or patient engagement with DMHIs aiming to monitor or improve the mental or physical health of people with psychosis or bipolar disorder.

College of Artificial Intelligence, Nankai University, Tianjin, 300350, China.
Motivation: The drug-disease, gene-disease, and drug-gene relationships, as high-frequency edge types, describe complex biological processes within the biomedical knowledge graph. The structural patterns formed by these three edges are the graph motifs of (disease, drug, gene) triplets. Among them, the triangle is a steady and important motif structure in the network, and other various motifs different from the triangle also indicate rich semantic relationships.

Background: Podcasts are an unconventional method of disseminating information through audio to the masses. They are an emerging portable technology and a valuable resource that provides unlimited access for promoting health among participants. Podcasts related to health care have been used as a source of medical education, but there is a dearth of studies on the use of podcasts as a source of health information.
