The majority of studies on parent-child discrepancies in the assessment of adolescent emotional and behavioral problems have been conducted in Western countries. It is believed that parent-adolescent agreement would be higher in societies with a strong culture of familism. We examined whether parent-adolescent discrepancies in the rating of adolescent emotional and behavioral problems are related to parental and family factors in Taiwan. Participants included 1,421 child-parent pairs of 7th-grade students from 12 middle schools in Northern Taiwan and their parents. We calculated Pearson’s correlation coefficients to assess the relationship between parental (Child Behavior Checklist, CBCL) and adolescent (Youth Self Report, YSR) report of emotional/behavioral problem syndromes. Regression models were used to assess parent-adolescent differences in relation to parental psychopathology and family factors. We found that parent-adolescent agreement was moderate (r = 0.37). Adolescents reported higher symptom scores than their parents (Mean Total Problem Score: CBCL: 20.79, YSR: 33.14). Parental psychopathology was related to higher parental ratings and better informant agreement. Parents with higher socioeconomic status (SES) tended to report lower scores for adolescent problem syndromes, resulting in higher levels of disagreement. Greater maternal care was related to higher parent-adolescent agreement. Based on our study findings, we conclude that familism values do not seem to improve parent-child agreement in the assessment of adolescent problem syndromes. The finding that higher SES was related to increased discrepancies speaks to the need to explore the culture-specific mechanisms giving rise to informant discrepancies.

The adsorption of molecular hydrogen on few-layer graphene (FLG) structures is studied using molecular dynamics simulations. The interaction between graphene and hydrogen molecules is described by the Lennard-Jones potential. The effects of pressure, temperature, number of layers in a FLG, and FLG interlayer spacing are evaluated in terms of molecular trajectories, binding energy, binding force, and gravimetric hydrogen storage capacity (HSC). The simulation results show that the effects of temperature and pressure can offset each other to improve HSC. An insufficient interlayer spacing (0.35 nm) largely limits the HSC of FLG because hydrogen adsorbed at the edges of the graphene prevents more hydrogen from entering the structure. A low temperature (77 K), a high pressure, a large number of layers in a FLG, and a large FLG interlayer spacing maximize the HSC.
