Differential game analysis of joint emission reduction decisions under mixed carbon policies and CEA.

To understand joint emission reduction (JER) of upstream and downstream firms under a low-carbon operational environment, this study incorporates green technology, remanufacturing, low-carbon promotion, consumer environmental awareness (CEA), and mixed carbon policies (carbon tax + cap-and-trade) into a dynamic framework to investigate JER decisions of the upstream manufacturer and the downstream retailer. Applying the differential game theory, we consider low-carbon goodwill as the state variable and explore members' optimal decisions in four cases, namely, idealized case, noncooperative case, unilateral cost-sharing contract (UCSC) case, and bilateral cost-sharing contract (BCSC) case. Our results show that the noncooperative case leads to a loss of efficiency in joint emission reduction.

Prepubertal exposure to polycyclic aromatic hydrocarbons are associated with early pubertal development onset in boys: A longitudinal study.

Objective: To investigate the effects of polycyclic aromatic hydrocarbons(PAHs) on puberty in boys.

Methods: 695 subjects were selected from four primary schools in Chongqing, China. 675 urine samples from these boys were collected four PAH metabolites: 1-hydroxypyrene, 2-hydroxynaphthoic, 2-hydroxyfluorene, and 9-hydroxyphenanthrene.

Emotional and Behavioral Changes in Preschool Firstborn Children During Transition to Siblinghood: A Mixed Methods Study.

Purpose: To help firstborn children in families expecting a second child navigate the role transition more smoothly, we investigated the emotional and behavioral changes of firstborn children during the transition to siblinghood (TTS) and the factors that contribute to these changes.

Patients And Methods: From March to December 2019, a total of 97 firstborn children (Mage=3.00± 0.

Co-Development and Bidirectional Associations Between Psychological Stress and Obesity in School-Aged Children: A Longitudinal Study in China.

Objective: Psychological stress (PS) has always been a hot topic for researchers to investigate the potential determinants of childhood overweight/obesity. Up to now, cohort studies investigating the relationship between PS and childhood obesity have used different ways to assess PS, different indicators to measure obesity, and different analysis methods, and the results were also inconsistent.

Methods: Data were obtained from the second to eighth follow-up of an ongoing cohort of school-aged children in Chongqing, China (June 2015-June 2018), with seven waves (W1-W7, NW1 = 1419).

The influence of the trajectory of obesity indicators on the age of pubertal onset and pubertal tempo in girls: A longitudinal study in Chongqing, China.

Objective: This study aims to explore the influence of the trajectory of obesity indicators on the onset age of different pubertal development characteristics and pubertal tempo among girls.

Methods: Our longitudinal cohort study recruited 734 girls at baseline in May 2014 from a district of Chongqing and followed them at 6-month intervals. Data were available from baseline to the 14th follow-up with a full record of height, weight, waist circumference (WC), breast development, pubic hair, and armpit hair development, as well as the age of menarche.

Polycyclic aromatic hydrocarbons are associated with later puberty in girls: A longitudinal study.

The objective of this study is to explore associations between PAH exposures and puberty timing in girls. Beginning in May 2014, 734 girls age 7.2-11.

Emotional and Behavioral Changes and Related Factors of Firstborn School-Aged Compared to Same Age Only Children.

Objective: To compare the emotional and behavioral characteristics of firstborn children during the pregnancy of a second child and only children of school-age in urban districts of Chongqing, China, and to explore the influencing factors of emotional and behavioral problems.

Methods: We recruited mothers of firstborn children and only children from two hospitals and one primary school using purposive sampling. Questionnaires and the Parental Child Behavior Checklist (CBCL) were used to collect basic information, family socioeconomic status, family atmosphere and emotional and behavioral characteristics of their children in the survey.

Implementation of environmental regulation strategies for nitrogen pollution in river basins: a stakeholder game perspective.

With the rapid development of modern agriculture, non-point source nitrogen pollution from higher polluting farms has become one of the main contributions to the eutrophication of the watershed. This paper first constructed a tripartite evolutionary game model concerning local governments, higher polluting farms, and consumers, all of which participate in the reduction of nitrogen pollution in the river basin. Secondly, the evolution process of evolutionary stability strategy (ESS) and the impact of critical parameters on the strategies of the three stakeholders were analyzed through numerical simulation.

Depression in Children and Adolescents on the Qinghai-Tibet Plateau: Associations with Resilience and Prosocial Behavior.

Depression in children and adolescents has become a serious public health problem worldwide. The objectives of this study were twofold: first, to investigate the status of depression among children and adolescents on the Qinghai-Tibet Plateau, the highest plateau in the world, with an average altitude of more than 4200 m (13,776 feet), and second, to examine the associations among prosocial behavior, resilience, and depression. A cross-sectional study was conducted among children and adolescents from Yushu Prefecture on the Qinghai-Tibet Plateau.

Regular Open-Skill Exercise Generally Enhances Attentional Resources Related to Perceptual Processing in Young Males.

This study aimed to examine whether the regular open-skill exercise led to a selective improvement or a general improvement on cognitive function in healthy young males. Besides, we also intend to expand previous studies by looking into the temporal dynamics of early information processes and cognitive processes through appraising the extensive temporal series of stimulus-locked ERP components. Sixty healthy young males were classified into two groups: those who regularly participated in the open-skill exercise for at least 2 years ( = 30), and those who exercised rarely.
