Although tantrums are among the most common behavioral problems of young children and may predict future antisocial behavior, little is known about them. To develop a model of this important phenomenon of early childhood, behaviors reported in parental narratives of the tantrums of 335 children aged 18 to 60 months were encoded as present or absent in consecutive 30-second periods. Principal Co...

The present study investigated gender differences in the associations between the DRD4 variable number tandem repeat (VNTR) polymorphism and adolescent delinquency, short temper and thrill seeking. We also explored whether the gender-specific expression of the DRD4 can be explained by gender differences in the exposure to psychosocial risks, such as poor parent-child relationship. Participants ...

The study on temper embrittlement and hydrogen embrittlement of a test block from a 3Cr1Mo1/4V hydrogenation reactor after ten years of service was carried out by small punch test (SPT) at different temperatures. The SPT fracture energy Esp (derived from integrating the load-displacement curve) divided by the maximum load (Fm) of SPT was used to fit the Esp/Fm versus-temperature curve to determ...

Abstract The present study investigates the effect of building orientation and heat treatment routes on mechanical behavior AlSi7Mg alloy (A357) produced by Laser Powder Bed Fusion. microstructure A357 in as built, T5 (directly aged) T6 (solution treated, water quenched conditions were compared. Tensile properties material evaluated along two main directions (parallel normal to platform), where...

The continuously annealed low-carbon-steel strips from industrial production showed an average aging index of about 30 N/mm². This increase in yield strength caused by the continuous-annealing process was strongly dependent on soaking temperature and time. Whilst optimization overaging parameters use a higher annealing would reduce ageing susceptibility strips, it considered unlikely that its m...

Several neurodevelopmental disorders are associated with preference for routine and challenging behavior following changes to routines. We examine individuals with Prader-Willi syndrome, who show elevated levels of this behavior, to better understand how previous experience of a routine can affect challenging behavior elicited by disruption to that routine. Play based challenges exposed 16 part...
