Adolescents' offline and online social support: A study on latent groups and their relationship with mental health.

Introduction: The internet has become a common space for adolescents to connect with others and find information. However, it remains unclear whether online encounters can serve as new sources of social support for Chinese adolescents. The present study aimed to identify distinct patterns in Chinese adolescents' social support from both offline and online sources and to examine how these patterns relate to individual and family factors and adolescents' mental health conditions.

High-Performance Graphene Nanowalls/Si Self-Powered Photodetectors with HfO as an Interfacial Layer.

Graphene/silicon (Si) heterojunction photodetectors are widely studied in detecting of optical signals from near-infrared to visible light. However, the performance of graphene/Si photodetectors is limited by defects created in the growth process and surface recombination at the interface. Herein, a remote plasma-enhanced chemical vapor deposition is introduced to directly grow graphene nanowalls (GNWs) at a low power of 300 W, which can effectively improve the growth rate and reduce defects.

A modified CVD method for the synthesis of monolayer MoSand photoelectric improvement by HfOpassivation.

Molybdenum disulfide (MoS) is an emerging class of new materials with a wide range of potential practical applications. However, the uncontrollability of monolayer MoSsynthesized by traditional chemical vapor deposition method and the low responsivity of MoSphotodetectors limit its further development in the field of photoelectric detection. To achieve controlled growth of monolayer MoSand construct MoSphotodetectors with a high responsivity, we propose a novel single crystal growth strategy of high-quality MoSby controlling the Mo to S vapor ratio near the substrate, and deposit a layer of hafnium oxide (HfO) on the surface of MoSto enhance the performance of the pristine metal-semiconductor-metal structure photodetector.

Examination of Web-Based Single-Session Growth Mindset Interventions for Reducing Adolescent Anxiety: Study Protocol of a 3-Arm Cluster Randomized Controlled Trial.

Background: Anxiety disorders are the most common mental disorders worldwide. In Hong Kong, 7% of adolescents are diagnosed with anxiety disorders, and 1 in every 4 secondary school students reports clinical-level anxiety symptoms. However, 65% of them do not access services.

Measuring Online Social Support: Development and Validation of a Short Form for Chinese Adolescents.

Supportive interactions on social media have great potential to benefit adolescents' development. However, there is no instrument to measure online social support (OSS) in China. The study aimed to develop and validate a Chinese short version of the Online Social Support Scale (OSSS).

Online Peer-Support Group's Role in Addressing Filipino Domestic Workers' Social Support Needs: Content and Social Media Metrics Analysis.

The study aimed to examine what types of social support a prominent online peer support group has provided to Filipino domestic workers (FDWs) in Hong Kong (HK), how impactful each type of support was, and to what extent the support could address group members' expressed needs. Posts published from 1 September 2021 to 31 December 2021 in one of the largest online peer-support groups for FDWs in HK and their meta-data were extracted from Facebook. Thematic content analysis was performed to extract relevant information from the posts.

Peer Support and Mental Health of Migrant Domestic Workers: A Scoping Review.

The effectiveness of peer support in improving mental health and well-being has been well documented for vulnerable populations. However, how peer support is delivered to migrant domestic workers (MDWs) to support their mental health is still unknown. This scoping review aimed to synthesize evidence on existing peer support services for improving mental health among MDWs.

Relationship between online social support and adolescents' mental health: A systematic review and meta-analysis.

Introduction: The potential benefits of supportive interactions on social networking sites on adolescents' mental health are promising; however, no systematic evaluation has been conducted on this topic. This review examined empirical research on the relationship between social support derived from social networking sites and adolescents' mental health both theoretically and empirically.

Methods: Followed PRISMA guidelines, we conducted a systematic literature search on six English and three Chinese databases in February 2020.

Understanding the Better Than Average Effect on Altruism.

Prior research suggests that most people perceive themselves to be more altruistic than the average population, an observation known as the better-than-average (BTA) effect. Understanding the BTA effect carries significant public health implications, as self-perceived altruism is closely related to altruistic behaviors, which plays a significant role in individual and societal well-being. However, little is known about whether subpopulations with specific sociodemographic profiles are more likely to hold BTA altruistic self-perceptions, making it difficult to design targeted programs based on multiple sociodemographic characteristics to promote altruistic behaviors.

The Relationship Between Images Posted by New Mothers on WeChat Moments and Postpartum Depression: Cohort Study.

Background: As social media posts reflect users' emotions, WeChat Moments, the most popular social media platform in China, may offer a glimpse into postpartum depression in the population.

Objective: This study aimed to investigate the features of the images that mothers posted on WeChat Moments after childbirth and to explore the correlation between these features and the mothers' risk of postpartum depression.

Methods: We collected the data of 419 mothers after delivery, including their demographics, factors associated with postpartum depression, and images posted on WeChat Moments.

Optimizing the Electronic Structure of InO through Mg Doping for NiO/InO p-n Heterojunction Diodes.

InO is a wide bandgap oxide semiconductor, which has the potential to be used as an active material for transparent flexible electronics and UV photodetectors. However, the high concentration of unintentional background electrons existing in InO makes it hard to be modulated by the electric field or form p-n heterojunctions with a sufficient band-bending width at the interface. In this work, we report the reduction of the background electrons in InO by Mg doping (Mg-InO) and thereby improve the device performance of p-n diodes based on the NiO/Mg-InO heterojunction.

Single-Crystalline Metal Oxide Nanostructures Synthesized by Plasma-Enhanced Thermal Oxidation.

To unravel the influence of the temperature and plasma species on the growth of single-crystalline metal oxide nanostructures, zinc, iron, and copper foils were used as substrates for the study of nanostructure synthesis in the glow discharge of the mixture of oxygen and argon gases by a custom-made plasma-enhanced horizontal tube furnace deposition system. The morphology and microstructure of the resulting metal oxide nanomaterials were controlled by changing the reaction temperature from 300 to 600 °C. Experimentally, we confirmed that single-crystalline zinc oxide, copper oxide, and iron oxide nanostructures with tunable morphologies (including nanowires, nanobelts, etc.
