The Relationship

We investigated autonomic arousal, attention and response conflict, in ADHD and autism. Heart rate variability (HRV), and behavioral/electrophysiological indices of performance, were recorded during a task with low and high levels of response conflict in 78 children/adolescents (7–15 years old) with ADHD, autism, comorbid ADHD+autism, or neurotypical. ANOVA models were used to investigate effects of ADHD and autism, while a mediation model was tested to clarify the relationship between ADHD and slower performance. Slower and less accurate performance characterized ADHD and autism; however, atypical electrophysiological indices differently characterized these conditions. The relationship between ADHD and slower task performance was mediated by reduced HRV in response to the cue stimulus. Autonomic hypo-arousal and difficulties in mobilizing energetic resources in response to sensory information (associated with ADHD), and atypical electrophysiological indices of information processing (associated with autism), might negatively affect cognitive performance in those with ADHD+autism.

Violent Offenses

The purpose of this study was to examine violence against women (VAW) in the National Football League (NFL). Since Ray Rice assaulted his partner on video, VAW by NFL players has received more public attention. However, there is little empirical research that examines VAW in the NFL and player suspensions compared to other violations. Data come from a public list of 176 NFL players known to have violated NFL policies from 2010–2019. Four major types of violations were found: VAW included sexual assault, rape, and domestic violence; general violent behaviors included assault or battery; drug-related offenses included substance abuse, alcohol, driving under the influence (DUI's), illegal drugs, and performance-enhancing drugs (PEDs); and minor sports-related infractions included issues such as missing a team meeting. The average number of game suspensions was 4.08 for VAW offenses, 1.75 for general violent offenses, 4.05 for drug-related offenses and 1.88 for minor infractions. We found no differences in the number of game suspensions for drug-related offenses compared to VAW; general violent offenses had even fewer suspensions. These numbers are contradictory to the NFL's Personal Conduct Policy of a 6-game suspension without pay for VAW and general violence.

The Relationship

PurposeThe purpose of this study was to extend our knowledge of the relationship between quantitative and qualitative job insecurity and performance. On the basis of stress theories, we hypothesised that qualitative job insecurity (QLJI) would mediate the negative effect of quantitative job insecurity (QTJI) on two different indicators of performance: task performance (TP) and counterproductive work behaviours (CPWBs). In addition, the authors hypothesised that the effect of QTJI on QLJI would be moderated by the economic sector (public vs private) in which employees worked. Therefore, the authors empirically tested a moderated mediation model via PROCESS.Design/methodology/approachParticipants were 431 employees from various Italian organisations. Data were collected using a self-report questionnaire measuring QTJI, QLJI, TP and CPWBs.FindingsThe results indicated that economic sector moderated the relationship between quantitative and QLJI. Both quantitative and QLJI were related to performance outcomes. Furthermore, QLJI mediated the effect of QTJI on TP and CPWB. However, this mediation was particularly apparent among employees in the private sector, supporting our hypothesised moderated mediation model.Practical implicationsThe results suggest that managers of private and public organisations need to apply different policies to reduce the impact of job insecurity on CPWBs and increase the TP of their employees.Originality/valueThis study attempted to examine the job insecurity–performance relationship in more depth. For the first time, the effects of both job insecurity dimensions on performance were simultaneously investigated, with economic sector as a moderator and QLJI as a mediator.
