Physiological Self-Regulation Buffers the Relationship between Impulsivity and Externalizing Behaviors among Nonclinical Adolescents

Trait impulsivity is a risk factor for rule breaking and aggressive (externalizing) behaviors among nonclinical youth. Buffers of trait-based risk are of practical interest to preventing externalizing behaviors. One such buffer may be the capacity and efforts of a child to self-regulate their physiology. Youth who possess baseline physiological self-regulatory capacities are more likely to maintain adaptive engagement with their environment and may be less prone to impulsively rule break or be aggressive. Similarly, youth who are able to use self-regulatory skills to calm their physiology in times of stress may be less likely to externalize distress. This study examined self-regulatory capacity and efforts as a moderator of the relationship between trait impulsivity and externalizing behaviors, cross-sectionally and prospectively. We hypothesized that the effect of trait impulsivity on externalizing behaviors would depend on the presence of baseline self-regulatory capacity and/or self-regulatory efforts during stress. Participants were 134 nonclinical adolescents (M_age?=?12.59, SD?=?1.20 51.9% female, 71% Caucasian). Trait impulsivity was measured using a parental report questionnaire. Physiological self-regulatory capacity and efforts were measured through collection of electrocardiogram data during a resting baseline and a stressful, unsolvable anagram task, respectively. Physiological self-regulation was quantified by calculating respiratory sinus arrhythmia scores across baseline and stress tasks. Respiratory sinus arrhythmia is the change in heart rate across the breathing cycle, and is hypothesized to index physiological self-regulation capacity and efforts under specific conditions. The results indicated that physiological self-regulation capacity, but not efforts, moderated the effect of trait impulsivity on externalizing behaviors prospectively. Stronger physiological self-regulatory capacity buffered the effect of greater trait impulsivity. Implications of these findings among typically developing youth are discussed.

At-Home Environment, Out-of-Home Environment, Snacks and Sweetened Beverages Intake in Preadolescence, Early and Mid-Adolescence: The Interplay Between Environment and Self-Regulation

Obesity-related behaviors, such as intake of snacks and sweetened beverages (SSB), are assumed to result from the interplay between environmental factors and adolescents’ ability to self-regulate their eating behaviors. The empirical evidence supporting this assumption is missing. This study investigated the relationships between perceptions of at-home and out-of-home food environment (including SSB accessibility, parental, and peers’ social pressure to reduce intake of SSB), nutrition self-regulatory strategies (controlling temptations and suppression), and SSB intake. In particular, we hypothesized that these associations would differ across the stages of preadolescence, early and mid-adolescence. Self-reported data were collected from 2,764 adolescents (10–17 years old; 49 % girls) from 24 schools in the Netherlands, Poland, Portugal, and the United Kingdom. Path analysis indicated that direct associations between peers’ social influence and SSB intake increased with age. Direct negative associations between at-home and out-of-home accessibility and SSB intake as well as direct positive associations between parental pressure and intake become significantly weaker with age. Accessibility was related negatively to self-regulation, whereas higher social pressure was associated with higher self-regulation. The effects of the environmental factors were mediated by self-regulation. Quantitative and qualitative differences in self-regulation were observed across the stages of adolescence. The associations between the use of self-regulatory strategies and lower SSB intake become significantly stronger with age. In preadolescence, SSB intake was regulated by means of strategies that aimed at direct actions toward tempting food. In contrast, early and mid-adolescents controlled their SSB intake by means of a combination of self-regulatory strategies focusing on direct actions toward tempting food and strategies focusing on changing the psychological meaning of tempting food.     

Tracing the terrain of Indigenous food sovereignties

Food sovereignty scholars are increasingly re-conceptualizing sovereignty by accounting for its diverse expressions across space according to specific histories, identities, and local socio-ecological realities and dynamics. In grappling with the multiple bases of sovereignty, attention has been directed toward Indigenous food sovereignty in North America. Specifically, food scholars are examining how the regeneration of Indigenous food harvesting and sharing practices shapes movements for decolonization and self-determination. While this is a crucial and much-welcomed intervention, much more is needed to understand the diverse Indigenous political and legal orders and authorities that shape how multiple Indigenous food sovereignties are lived every day across diverse landscapes. In this contribution, I examine how Anishinaabe people in and beyond the Treaty 3 territory in Ontario, Canada, protect and renew their food harvesting grounds, waters and foodways through everyday acts of resurgence that are rooted in their law of mino bimaadiziwin.     

Practical Aspects of Analyzing Vegetable Oils in Fire Debris*

Abstract: Vegetable oils undergo burning, self‐heating, and spontaneous ignition, resulting in their presence in fire debris. As these processes can affect the fatty acid content of vegetable oils, it is important that debris be properly handled in order to obtain reliable and informative data. This research investigated changes in vegetable oil content as a result of storage conditions and different types of burning. Material spiked with vegetable oils and burned was stored under various long‐term conditions, and debris was tested by heating overnight using passive headspace concentration. Results indicated that refrigeration is ideal for fire debris samples suspected of containing vegetable oils and that including passive headspace concentration in the analytical scheme would not affect oils. Spontaneous ignition experiments were conducted to compare the effects of various burning processes on vegetable oil content. Vegetable oils that experienced nonpiloted ignition, self‐heating, and spontaneous ignition produced noticeably different chromatograms from those that underwent piloted ignition.     

The Dynamic Prediction of Criminal Recidivism: A Three-wave Prospective Study

A three-wave, prospective panel design was used to assess the extent to which static and dynamic risk factors could predict criminal recidivism in a sample of 136 adult male offenders released from Canadian federal prisons. Static measures were assessed only once, prior to release while dynamic measures were assessed on three separate occasions: pre-release, 1 month, and 3 months post-release. Recidivism was coded during an average of 10.2-month follow-up period (SD = 19.2). A series of Cox regression survival analyses with time-dependent covariates and Receiver Operator Characteristic (ROC) analyses were conducted to assess predictive validity. Although the combined static and time-dependent dynamic model (AUC = .89, CI = .81–.93) significantly (p < .01) outperformed the pure static model (AUC = .81, CI = .73–.87) the confidence intervals did overlap to some extent. Implications for dynamic risk assessment and management are discussed.

The Timeline Followback Interview to Assess Children’s Exposure to Partner Violence: Reliability and Validity

This study evaluated psychometric properties of the Timeline Followback interview—Children’s Exposure to Partner Violence (TLFB-CEPV), an event history calendar interview designed to assess children’s exposure to daily patterns of intimate partner violence. Participants were men (N = 107) entering batterer’s treatment, their female partners, and a custodial child (6–16 years). The TLFB-CEPV asked about days of partner physical aggression and children’s exposure to these episodes, and was administered to partners at pretreatment, posttreatment, 6 and 12 months. At each assessment, the percentage of days of any child exposure (PAE) and of children’s direct exposure (PDE) to violence were calculated. Parents completed measures of partner aggression and social desirability; parents, teachers, and children completed measures of children’s adjustment. TLFB-CEPV scores had excellent temporal stability and strong evidence of concurrent, discriminant, and criterion validity. Interrater agreement for TLFB-CEPV scores was moderate at initial assessment, but high at subsequent follow-up interviews. This project was supported, in part, by grants from the National Institute on Drug Abuse (R01DA12189, Fals-Stewart), the Alpha Foundation, and Old Dominion University.     

Violence between therapy-seeking veterans and their partners: prevalence and characteristics of nonviolent, mutually violent, and one-sided violent couples

Among male veterans and their female partners seeking therapy for relationship issues, three violence profiles were identified based on self-reports of physical violence: nonviolent, in which neither partner reported perpetrating physical violence (44%); one-sided violent, in which one partner reported perpetrating violence (30%); and mutually violent, in which both partners reported perpetrating physical violence (26%). Profiles were distinguished based on the veteran's psychiatric diagnosis, woman's age, and both partners' reports of the frequency and severity of violence. Men and women in mutually violent couples reported more verbal and physical aggression than did men or women in any other group. The three groups reported comparable rates of sexual aggression. Appraisals of marital satisfaction and intimacy were not different based on violence profile. No gender differences emerged in the self-reports of frequency and severity of verbal, physical, and sexual aggression.
