Domain‐specific impulsivity in school‐age children [PDF]
Developmental Science, 2013 AbstractImpulsivity is a salient individual difference in children with well‐established predictive validity for life outcomes. The current investigation proposes that impulsive behaviors vary systematically by domain. In a series of studies with ethnically and socioeconomically diverse samples of middle school students, we find that schoolwork‐related

Rapid Estimation of Specific Impulse
Defence Science Journal, 1988 Specific impulse (Isp) is one of the important criteria for propellant characterisation. In the present paper a semiempirical approach has been suggested to calculate Isp of composite modified doublebase(CMDB) propellant formulations by utilizing calorimetric value(Cal-Val) of the propellant composition.

Characterizing motor impulsivity of individuals classified as overweight to obese
Sports Medicine and Health Science, 2023 Deficits in the impulse control system are an important predictor of energy intake and body weight. Adults classified as overweight to obese may possess these deficits as a general behavioral trait or they may be food-specific. The present study assessed
