Responses of depth-dependence of C:N:P stoichiometry to check dam in mangrove wetlands.
J Environ Manage
December 2024
Carbon (C) sequestration and nitrogen (N) and phosphorus (P) deposition in mangrove wetlands are significant for global climate regulation and the removal of marine nutrient pollutant. To protect and restore mangroves, numerous check dams have been implemented within mangrove wetlands; however, the influence of these check dams on C, N, and P content, stoichiometry, and their depth-dependence remains largely unexplored. To establish a causal relationship between the check dams and C and nutrient variations, we first determined soil deposition depth post-check dam construction in both a natural mangrove and a neighboring check dam-affected mangrove.

If structural equation modelling is applied to test effects of interest, the investigation of differential strength of effects will typically ask how parameters of a latent variable model are influenced by categorical or continuous moderators, such as age, socio-economic status, personality traits, etc. Traditional approaches to continuous moderators in SEMs predominantly address linear moderation effects, risking the oversight of nonlinear effects.

Basic concepts and fundamental issues relevant to BSEM are introduced, such as prior setting, model convergence, and model fit evaluation and so on. The paper also provides illustrative examples of commonly employed BSEMs, including confirmatory factor analysis (CFA) models, mediation models and multigroup CFA models, accompanied by empirical data and computer codes to facilitate implementation.

- This research introduces a new idea called "inter-PES," which helps understand how parents teach their teens to handle emotions in social situations.
- In three studies, parents and teens shared their thoughts about parenting and emotions, leading to the discovery of four important parts of inter-PES.
- The study finds that these four parts are connected to how kids feel and develop socially and emotionally, suggesting parents' perspectives during emotional learning are important for their teens.
Article Synopsis
- - The study explores how the foot-and-mouth disease virus (FMDV) relies on host cell lipid metabolism, specifically through the enzyme stearoyl coenzyme A desaturase-1 (SCD1), to replicate effectively.
- - Researchers found that increasing SCD1 levels or adding oleic acid boosted FMDV replication in various cell lines and that inhibiting SCD1 significantly reduced replication and affected the formation of replication complexes.
- - The findings suggest that targeting SCD1 could be a promising strategy for developing new antiviral drugs against FMDV and other RNA viruses, as it plays a critical role in their replication process.
Parent-adolescent emotion dynamics have attracted increasing attention in recent years because adolescence is a challenging period for both adolescents and parents. However, how emotions are coconstructed between parents and adolescents is less clear. This study examined whether mothers' and adolescents' emotion regulation strategy was linked with their own and each other's depression using the actor-partner interdependence model (APIM).

- This research focused on differentiating between person minimization and emotion minimization in Chinese families with adolescents.
- Five studies were conducted: the first developed a scale to measure these two types of minimization, while the subsequent studies explored their relationships with various socioemotional factors and responses in both mothers and children.
- Findings revealed that adolescents viewed emotion minimization more positively than person minimization, and identified a reciprocal relationship between problematic communication patterns related to emotional distress over time.
Article Synopsis
- The study explores how parenting, specifically parental responses to children's negative emotions, influences adolescents' hostile attribution biases (HAB).
- Conducted with 203 adolescents in mainland China, the research found that supportive responses from mothers led to a decrease in adolescents' HAB over time.
- Conversely, non-supportive responses and expressions of minimization did not significantly affect HAB, highlighting the importance of positive emotional socialization in children’s development.
Background And Aims: Emerging research has identified parents' psychological distress as a potential risk factor that increases adolescents' vulnerability to problematic gaming. This study attempted to address "why" from a relational perspective. We hypothesized that parents' psychological distress may link to adolescents' problematic gaming through the mediation of parent-child relationship quality, while the mediating effects of parent-child relationship quality may vary depending on adolescents' emotion regulation.

- The study focused on developing and validating a new scale, the PVRCANE, to measure how adolescents in China perceive their parents' responses to their negative emotions, incorporating both universal and culturally specific factors.
- The research involved two studies: the first with 901 participants to refine the scale, and the second with 320 participants to test its validity and reliability.
- The final PVRCANE proved to be a concise and effective tool, showing strong correlations with parental goals and adolescent depressive symptoms, contributing to the understanding of emotion socialization in a Chinese context.
Article Synopsis
- Online gaming is becoming more mainstream, but some individuals may develop Internet gaming disorder (IGD), characterized by a strong craving for games and a tendency to approach game-related cues.
- Researchers are now using a virtual reality (VR) approach-avoidance task (AAT) to study the approach bias in people with IGD, as traditional methods lack realism.
- Findings show that individuals with IGD took less time to approach game-related stimuli in VR, suggesting they struggle to avoid gaming cues, and that such stimuli do not necessarily increase their craving for games.
Article Synopsis
- * The Dongzhaigang mangrove area in China has declined from 3416 hectares in the 1950s to 1711 hectares by the 1990s, mainly due to human activities, although this area has stabilized since then due to conservation efforts.
- * Future predictions indicate that depending on greenhouse gas emissions (RCP scenarios), between 17% to over 26% of these mangroves could be lost by 2100, highlighting the need for strategies like restoration and afforestation to boost their resilience against sea level rise.
Article Synopsis
- The study aimed to assess the psychometric properties of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale, focusing on its factor structure and internal consistency.
- The bifactor model demonstrated good fit and reliability, while demographic factors like age, race/ethnicity, and autism severity influenced overall quality of life scores, but gender showed no impact.
- An optimal cut-off score of 37 for the QOLASD-C was identified, with implications for both research and practical applications in understanding children's quality of life.
Article Synopsis
- The study validated the Pediatric Symptom Checklist-Youth (PSC-Y) using a large sample of Chinese youth (N = 20,996) to assess its effectiveness in identifying psychosocial issues.
- Factor analysis confirmed a three-factor structure for the PSC-Y, categorizing issues into externalizing, internalizing, and attention problems, consistent with previous research.
- The findings also showed differences in reported problems based on gender and age, indicating that older students and females tended to report more internalizing and attention issues, which can help educators and psychologists better identify at-risk youth.
Article Synopsis
- - This research introduces the Communication Patterns of Adolescents' Emotional Distress (CPAED), focusing on how adolescents and their mothers communicate about emotions after distressing events.
- - Factor analyses revealed three main communication patterns: ARES (Active and Reactive Emotion Sharing), LS (Lack of Solicitation by mothers), and LR (Lack of Response by adolescents).
- - The study found that ARES was linked to lower emotional distress in adolescents, while LS and LR contributed to higher emotional distress, highlighting the impact of maternal communication styles on adolescents' emotional well-being.
This research aims to investigate the salience of mothers' emotional expressivity and its links with adolescents' emotional wellbeing and expressivity in an urban society endorsing more individualism and a rural society ascribing to more collectivism. By comparing Chinese urban ( = 283, = 14.13) and rural ( = 247, = 14.

Article Synopsis
- Autism spectrum disorders (ASD) present challenges such as social difficulties and communication issues, often complicating early detection due to slow traditional screening methods and limited healthcare resources.* -
- This study introduced a new method that uses eye movement data analyzed with machine learning algorithms to predict autistic traits, demonstrating significant potential for early screening.* -
- Preliminary results showed good accuracy with an ensemble model in predicting ASD traits, indicating that eye movement patterns, particularly attention to specific visual areas, can effectively differentiate individuals with varying levels of autistic traits.*
Our purpose in this study was to validate the Quality of Life for Children with Autism Spectrum Disorder scale. We first conducted an exploratory factor analysis to examine the factor structure. Results suggested that a three-factor model (Interpersonal Relationships, Self-Determination, and Emotional Well-Being) should be retained.
