Psychometric Properties of the Chinese Version of 20-Item Zimbardo Time Perspective Inventory (C-ZTPI-20) in Chinese Adolescent Population.

Background: This study assesses the psychometric properties of the Chinese version of the Zimbardo Time Perspective Inventory (C-ZTPI-20) in an adolescent population.

Methods: The investigation encompasses a sample of 2634 middle school students from China and aims to evaluate the instrument's reliability, structural validity, measurement invariance, criterion validity, and network structure attributes.

Results: First, descriptive analysis revealed satisfactory reliabilities for four out of five C-ZTPI-20 dimensions, with Present Fatalistic (PF) exhibiting relatively low reliability.

Multifarious Linkages Between Personality Traits and Psychological Distress During and After COVID-19 Campus Lockdown: A Psychological Network Analysis.

Background: The novel coronavirus disease pandemic is still proliferating and is not expected to end any time soon. Several lockdowns and social distancing measures might be implemented in the future. A growing body of research has explored the effect of personality on individuals' psychological wellbeing during the pandemic.

Constructions and Comparisons of Pooling Matrices for Pooled Testing of COVID-19.

In comparison with individual testing, group testing is more efficient in reducing the number of tests and potentially leading to tremendous cost reduction. There are two key elements in a group testing technique: (i) the pooling matrix that directs samples to be pooled into groups, and (ii) the decoding algorithm that uses the group test results to reconstruct the status of each sample. In this paper, we propose a new family of pooling matrices from packing the pencil of lines (PPoL) in a finite projective plane.

Problematic Internet use among residential college students during the COVID-19 lockdown: A social network analysis approach.

Background And Aims: During the COVID-19 lockdown, problematic Internet use (PIU) has become a serious issue among residential college students, who remain physically isolated from off-campus society. This study constructs an integrated model to investigate the influencing mechanisms of internal locus of control (LOC) and objective peer effects.

Methods: Residential college students (n = 494) were surveyed from a single department of a Chinese university.

Positively Correlated Samples Save Pooled Testing Costs.

The group testing approach, which achieves significant cost reduction over the individual testing approach, has received a lot of interest lately for massive testing of COVID-19. Many studies simply assume samples mixed in a group are independent. However, this assumption may not be reasonable for a contagious disease like COVID-19.

A Time-Dependent SIR Model for COVID-19 With Undetectable Infected Persons.

In this paper, we conduct mathematical and numerical analyses for COVID-19. To predict the trend of COVID-19, we propose a time-dependent SIR model that tracks the transmission and recovering rate at time [Formula: see text]. Using the data provided by China authority, we show our one-day prediction errors are almost less than [Formula: see text].

The Spillover Mechanisms Linking Family Conflicts and Juvenile Delinquency Among Chinese Adolescents.

The mechanisms through which conflicting parental relationship and parenting practices influence adolescent antisocial behavior have not been adequately understood. To bring more understanding to the mechanisms, this study investigates how marital discord interrelates with interparental inconsistency in parenting practices, and how these family conditions influence juvenile delinquency through their spillover effects on mental health problems, parental attachment and delinquent peer association among Chinese adolescents. Findings obtained from a structural equation modeling analysis of survey data collected from a probability sample of 2,496 adolescents (mean age = 15.

The Interrelationship between Family Violence, Adolescent Violence, and Adolescent Violent Victimization: An Application and Extension of the Cultural Spillover Theory in China.

The current study is the first study to emphasize family systems, violent norms, and violent peer association as three domains of the social environment that influence both adolescent violent offending and victimization among Chinese adolescents using a longitudinal sample. Under the framework of cultural spillover theory, the purpose of the current study was to explore how these three factors influenced adolescent violent offending and victimization. A total of 1192 middle and high school students were randomly selected from one of the largest cities in Southwest China.

Experimental and numerical estimations into the force distribution on an occlusal surface utilizing a flexible force sensor array.

This study presents a novel flexible force sensor array for measuring the distribution of the force distribution over the first molar. The developed force sensor array is composed of a flexible polyimide electrode and barium-titanate-based multilayer ceramic capacitors (MLCCs). The piezoelectric and material properties of industrial-grade MLCCs are ideal for measuring large-force loadings.

Pharmaceutical poisoning exposure and outcome analysis in children admitted to the pediatric emergency department.

Background: Pharmaceuticals involved in childhood poisoning vary, and treatment of poison exposure can be a challenge for primary physicians when children are unconscious or histories are lacking. Knowledge of the clinical manifestations and prognosis of poisoning will help primary physicians perform appropriate clinical assessments. In this study, we aim to report on patient characteristics, outcomes, and clinical features of pediatric poisoning in the emergency department.

Predictive factors of the duration of a first-attack acute urticaria in children.

Purposes: This study's aim was to determine the predictive factors of the duration of first-attack acute urticaria in children.

Basic Procedures: The sample included 1075 children admitted to the emergency department with first-attack acute urticaria. Variables comprising the clinical features and past histories of children with duration of disease of 3 days or less, 4 to 7 days, 8 to 14 days, and 15 days or more were compared to determine the predictors of duration of acute urticaria.

Significant factors associated with severity and outcome of an initial episode of acute urticaria in children.

The aim of this study was to determine the predictive factors of severity and duration of an initial episode of acute urticaria in children. This was a retrospective study of 1120 children of <18 yr who presented to the emergency department (ED) with an initial episode of acute urticaria during the period January 1, 2001, to December 31, 2007. These patients were followed in the ED or outpatient department (OPD) until their symptoms subsided.

First attack of acute urticaria in pediatric emergency department.

Background: Management of a first attack of acute urticaria in children is dependent on the etiology of the disease. Knowledge of the various etiologies of urticaria will help primary physicians to perform appropriate clinical assessments. In this study, we analyzed the etiologies and their prevalence in first-attack acute urticaria in infants, children and adolescents in central Taiwan.
