The comorbidity mechanism of problematic internet use and depression among Chinese college students: A cross-lagged panel network analysis.

Problematic internet use (PIU) and depression usually co-occur and are common among college students. According to network theory, it may be attributed to the interplay of symptoms that connect these two mental health problems. However, most studies have failed to examine complex and subtle connections at the symptom level and have not clarified how PIU and depression symptoms are intercorrelated, which symptoms serve as the source of comorbidity (i.

Associations Between Internet-Specific Parenting, General Parenting, and Adolescents' Online Behaviors: A Cross-Lagged Panel Network Analysis.

Parents play a crucial role in adolescents' Internet use. Both general parenting (i.e.

Engineering extracellular electron transfer to promote simultaneous brewing wastewater treatment and chromium reduction.

Microbial fuel cell (MFC) technology has been developed for wastewater treatment in the anodic chamber, and heavy metal reduction in the cathodic chamber. However, the limited extracellular electron transfer (EET) rate of exoelectrogens remained a constraint for practical applications of MFCs. Here, a MFC system that used the electricity derived from anodic wastewater treatment to drive cathodic Cr reduction was developed, which enabled an energy self-sustained approach to efficiently address Cr contamination.

The Associations Between Parental Phubbing, Adolescent Phubbing, and Adolescents' Adjustments: A Cross-Lagged Panel Network Analysis.

A growing body of research indicates that phubbing can negatively influence adolescent development, it is not clear how perceived parental phubbing, adolescent phubbing, and adolescents' adjustment problems concurrently relate to each other at the dimension level. This study conducted the contemporaneous network analyses and cross-lagged network analysis to examine the distinct relationships between the various dimensions of perceived father phubbing, perceived mother phubbing, adolescent phubbing and adolescent's adjustment problems. A total of 1447 Chinese students (60.

Autonomy-relatedness Patterns and their Association with Academic and Psychological Adjustment among Chinese Adolescents.

Establishing autonomy and maintaining relatedness with parents are two of the most crucial goals for adolescents and meeting these goals can be critical for academic and psychological adjustment. A two-dimensional framework was proposed for exploring the integrative synthesis of autonomy and relatedness, but its cultural applicability was limited. To better account for the situations associated with non-Western cultural context, this study extended the prior framework to three dimensions (volition, functional independence, and relatedness) and utilized latent profile analysis to explore the configurations and their concurrent and longitudinal (one year later) associations with adjustment (academic engagement, academic buoyancy, depressive symptoms, and externalizing problems).

Predictive value of machine learning in diagnosing cognitive impairment in patients with Parkinson's disease: a systematic review and meta-analysis.

Background: The current process used to diagnose cognitive impairment in patients with Parkinson's disease (PD) is unsatisfactory. More and more researchers had introduced machine learning into this field in recent years. This study explored the application of machine learning and its diagnostic performance in this field.

Peer Victimization and Subjective Well-Being Among Chinese Adolescents: Moderated Mediation by Forgiveness and Self-Esteem.

Considerable developmental research has shown an association between peer victimization and subjective well-being among adolescents. However, the mediating processes and protective factors that constrain this association are less understood. To fill these gaps, we investigated whether self-esteem mediates the association between peer victimization and subjective well-being and whether forgiveness moderates the direct and indirect associations of peer victimization with adolescents' subjective well-being via self-esteem.

Circularly polarized electroluminescence from a single-crystal organic microcavity light-emitting diode based on photonic spin-orbit interactions.

Circularly polarized (CP) electroluminescence from organic light-emitting diodes (OLEDs) has aroused considerable attention for their potential in future display and photonic technologies. The development of CP-OLEDs relies largely on chiral-emitters, which not only remain rare owing to difficulties in design and synthesis but also limit the performance of electroluminescence. When the polarization (pseudospin) degrees of freedom of a photon interact with its orbital angular momentum, photonic spin-orbit interaction (SOI) emerges such as Rashba-Dresselhaus (RD) effect.

Developmental Trajectories of Adolescent Internet Addiction: Interpersonal Predictors and Adjustment Outcomes.

Despite the burgeoning literature on adolescent internet addiction (IA), the majority of studies have relied on cross-sectional designs and variable-centered analytical approaches. Therefore, little is understood about the heterogeneous developmental trajectories of adolescent IA as well as its antecedents and outcomes. This longitudinal study adopted growth mixture modeling (GMM), a person-centered approach, to identify the distinct trajectories of IA among adolescents during a three-year period.

Dyadic Profiles of Sexual Satisfaction among Chinese Newlywed Couples over Time.

Although sexual satisfaction is a defining feature of marriage, research has consistently found that sexual satisfaction declines over time. Recently, however, emerging findings provide a more optimistic perspective on sexual satisfaction development by suggesting that couples may follow diverse sexual satisfaction trajectories. Using Dyadic Latent Class Growth Analysis, the current study is among the first to examine heterogeneity in couples' sexual satisfaction trajectory patterns during the early years of marriage and the first to do so in a non-Western context.

Engineering a newly isolated exoelectrogen from activated sludge, to enhance methyl orange degradation and bioelectricity harvest.

Electroactive microorganisms (EAMs) play important roles in biogeochemical redox processes and have been of great interest in the fields of energy recovery, waste treatment, and environmental remediation. However, the currently identified EAMs are difficult to be widely used in complex and diverse environments, due to the existence of poor electron transfer capability, weak environmental adaptability, and difficulty with engineering modifications, etc. Therefore, rapid and efficient screening of high performance EAMs from environments is an effective strategy to facilitate applications of microbial fuel cells (MFCs).

Peer victimization and problematic internet use in adolescents: The mediating role of deviant peer affiliation and the moderating role of family functioning.

The role of social-environmental factors in adolescent problematic Internet use (PIU) has attracted considerable attention recently. Several studies have documented that peer victimization is positively associated with PIU. However, little is known about "how" (i.

The role of stressful life events and the Big Five personality traits in adolescent trajectories of problematic Internet use.

Cross-sectional studies have shown that both stressors and personality vulnerability are risk factors for adolescent problematic Internet use (PIU). However, little is known about how both categories of factors in combination may contribute to the longitudinal development of PIU among adolescents. The aims of this study were to document the developmental pattern of PIU among adolescents and to examine how stressful life events and the Big Five personality traits jointly affect the development of PIU.

[Soil Salinity Estimation Based on Near-Ground Multispectral Imagery in Typical Area of the Yellow River Delta].

This study chooses the core demonstration area of 'Bohai Barn' project as the study area, which is located in Wudi, Shandong Province. We first collected near-ground and multispectral images and surface soil salinity data using ADC portable multispectral camera and EC110 portable salinometer. Then three vegetation indices, namely NDVI, SAVI and GNDVI, were used to build 18 models respectively with the actual measured soil salinity.

The toxic effect of lithium ion on neurons (PC12 cells) and Aβ42 molecules.

In this study, the neurotoxicity of Li ion and its effect on the morphologies of Aβ42 molecules were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays, fluorescence (FL), atomic force microscopy (AFM), and circular dichroism (CD) spectroscopy. MTT assays show that Li ion with a dosage level lower than 50 mg/l did not show detectable cytotoxicity on pheochromocytoma (PC12) cells whereas a dosage level higher than 100 mg/l resulted in significant cytotoxicity. The interaction between Aβ42 and Li ion occurs, and the quenching effect of Li ion on the fluorescence emission of AΒ42 is found to be concentration dependent, suggesting that Li ion can bind to the Aβ42 molecules.
