Gray’s revised Reinforcement Sensitivity Theory in relation to Attention-Deficit/Hyperactivity and Tourette-like behaviors in the general population

Attention-Deficit/Hyperactivity Disorder (ADHD) and Tourette Syndrome (TS) present as distinct conditions clinically; however, they show comorbidity and inhibitory control deficits have been proposed to underlie both. The role of reinforcement sensitivity in ADHD has been studied previously, but no study has addressed this in relation to TS-like behaviors in the general population. The present study examined these associations within the remit of the revised Reinforcement Sensitivity Theory (rRST). One hundred and thirty-eight participants completed psychometric measures of the rRST, and self-report checklists for ADHD- and TS-like behaviors

Lifetime Correction Using Fast-Off-Energy Response Matrix Measurements

International audienceFollowing the measurements done at MAX-IV * we try to exploit for the ESRF-EBS Storage Ring (SR) off-energy response matrix measurement for the optimization of Touschek lifetime. The measurements performed with fast AC steerers on- and off-energy are analyzed and fitted producing an effective model including quadrupole and sextupole errors. Several alternatives to extrapolate sextupoles strengths for correction are compared in terms of lifetime. For the time being none of the corrections could produce better lifetime than the existing empirically optimized set of sextupoles

The Additive Value of Positive Psychological Capital in Predicting Work Attitudes and Behaviors

Conventional wisdom over the years and recent research findings have supported the importance of positivity in the workplace. However, to date, empirical analysis has not demonstrated potential added value of recently emerging positive state-like constructs such as psychological capital over the more established positive traits in predicting work attitudes and behaviors. This study of a sample of employees (N=336) from a broad cross section of organizations and jobs found that their state-like psychological capital is positively related to desired extra-role organizational citizenship behaviors (OCBs) and negatively with undesired organizational cynicism, intentions to quit and counterproductive workplace behaviors. Except for individual OCBs, their psychological capital also predicted unique variance in the same attitudinal and behavioral outcomes beyond their demographics, core self-evaluation, and personality traits, and person-organization fit and person-job fit. The article concludes with implications these findings have for future research and practical application
