Broadband backscattering from scyphozoan jellyfish.

As the ecological importance of gelatinous organisms becomes increasingly appreciated, so has the need for improved knowledge of their abundance and distribution. Acoustic backscattering measurements are routine for fisheries assessments but are not yet widely used to survey populations of gelatinous zooplankton. The use of acoustic backscattering techniques to understand the distribution and abundance of organisms requires an understanding of their target strength (TS). This study presents a framework for a sound scattering model for jellyfish based on the Distorted Wave Born Approximation that incorporates size, shape, and material properties of individual organisms. This model, with a full three-dimensional shape rendition, is applied to a common species of scyphomedusa (Chrysaora chesapeakei) and verified experimentally with broadband (52-90 and 93-161 kHz) laboratory TS measurements of live individuals. Cyclical changes in the organism's shape due to swimming kinematics were examined, as well as averages over swimming position and comparisons with scattering from simpler shapes. The model predicts overall backscattering levels and broad spectral behavior within <2 dB. Measured TS exhibits greater variability than is predicted by scaling the size of the organism in the scattering model, showing that density and sound speed vary among individuals.

Do Sanctions Affect Undetected Sexual Offending?

Undetected sexual offending creates challenges for risk assessment since estimated sexual recidivism rates are based on documented charges or convictions. Courts and other stakeholders may be primarily interested in the true risk for sexual reoffense and not simply risk for detected sexual offenses. Attempts to study and quantify the rate of undetected sexual offending have resulted in a wide variety of estimates. In this study, we explore whether sanctions imposed for detected sexual offenses increase the detection rate of subsequent offenses, and thereby suppress undetected sexual offending in an exceptionally high-risk sample who were ultimately committed as Sexually Violent Persons. Results indicate the detection rate of sexual offenses increased following an initial sanction, subsequently decreasing the proportion of undetected to detected offending. This effect only occurred after the first sanction. Overall, the sample had a high detection rate and spent little time in the community before subsequent arrests. These results differ from other reports that high rates of sexual offenses go undetected.

Why are individuals over age 60 still committed as sexually violent persons?

Civilly committed sexually violent persons (SVPs) are a select group of individuals designated as high risk for future sexual violence. Despite risk reduction in older age, SVP programs are seeing aging client populations, with many individuals remaining committed after age 60 (60+). Recent research found a sexual recidivism rate of 7.5% for 60+ individuals released from an SVP civil commitment program. The current paper follows up by examining reasons why individuals remain committed after age 60. It compares SVPs discharged after age 60 to those who are 60+ but remain civilly committed. Results of bivariate analyses reveal older SVPs who remain committed have significantly higher actuarial risk scores and are more likely to be of minority race. Multivariate logistic regression analyses found actuarial risk scores (Static-99R) predicted continued commitment, after controlling for other relevant variables. Barriers to community reintegration and suggestions for multi-disciplinary case management for older SVPs are discussed.

Treatment Satisfaction in a Civil Commitment Facility for Sexually Violent Persons.

Evaluating patient satisfaction in therapeutic settings is consistent with a Risk-Needs-Responsivity (RNR) model. This study provides results from a program improvement initiative in a sexually violent person (SVP) civil commitment facility that queried patients and treatment providers about their satisfaction with therapeutic processes and assessment methods. Overall, patients reported high levels of satisfaction with treatment at the facility, with the highest levels of satisfaction on items about being treated with kindness and respect and staff acting professionally. Providers rated current assessment methods such as the Penile Plethysmography (PPG) assessment, polygraph testing, and neuropsychological testing as most helpful for patients in treatment progress; however, patients rated PPG assessment and polygraph testing as the least helpful of the assessments conducted. Soliciting patient feedback periodically could be important for maintaining treatment engagement and discovering opportunities to enhance patient satisfaction to treatment in a SVP civil commitment setting.

Vitamin D Status and Physical Activity during Wintertime in Forensic Inpatients-A Randomized Clinical Trial.

This study aimed to gain deeper knowledge about the relationship between vitamin D and physical activity in a sample of forensic inpatients. Sixty-seven male forensic inpatients participated. Participants were randomly assigned into an Intervention group (vitamin D) or a Control group (placebo). The Physical Activity-Rating (PA-R) questionnaire was used to measure physical activity from January to May. Vitamin D status was measured as 25-hydroxy vitamin D (25-OHD) pre- and post-intervention. The results revealed that vitamin D status at post-test was positively correlated with physical activity, but there was no effect of vitamin D supplementation looking at the two randomized groups. However, controlling for body mass index (BMI), the results showed an effect of BMI and a main effect of groups with a higher level of physical activity in the Intervention group. No interaction effects were found. Participants were also assigned into High and Low vitamin D groups based on the vitamin D status at post-test; i.e., the upper (75.1 nmol/L) and lower quartile (46.7 nmol/L). T-tests revealed that participants with a vitamin D status above 75 nmol/L showed significantly higher levels of physical activity than participants with a vitamin D status below 46.7 nmol/L. Thus, a vitamin D status above 75 nmol/L seems to be an optimal level.

Adverse Childhood Experiences Among Sexual Offenders: Associations With Sexual Recidivism Risk and Psychopathology.

Adverse childhood experiences (ACEs) are increasingly recognized as a public health crisis. Cumulative effects of these experiences lead to a wide range of deleterious physical and psychological outcomes. Prior research has identified higher prevalence rates of ACEs and increased criminal behavior in samples of individuals who have committed sexual offenses. In a sample of civilly committed individuals who have committed sexual offenses (N = 317), we examined the prevalence of ACEs (cumulative scores and the two components of child harm and family dysfunction) and their association with risk for sexual recidivism and adult psychopathology. ACEs were much more prevalent in this sample compared with the general population and to lower risk samples of individuals who had committed sexual offenses. Although ACE scores were unrelated to risk for sexual recidivism, higher ACE scores were associated with increased risk of psychopathology, including anxiety disorders, depressive disorders, substance use disorders, and Antisocial Personality Disorder. ACEs related to family dysfunction were uniquely associated with Alcohol Use Disorder and the presence of a dual diagnosis of a paraphilia and personality disorder. Results suggest that higher risk individuals who commit sexual offenses may have greater need for trauma-informed models of care that recognize the effect of these experiences on their mental health and offense-related behavior.

Vitamin D Supplementation during Winter: Effects on Stress Resilience in a Randomized Control Trial.

Vitamin D status may be important for stress resilience. This study investigated the effects of vitamin D supplements during winter on biological markers of stress resilience such as psychophysiological activity, serotonin, and cortisol in a placebo-controlled, randomized clinical trial. Eighty-six participants were randomly assigned to the Intervention (vitamin D) or Control (placebo) groups. Before and after the intervention participants were exposed to an experimental stress procedure. Psychophysiological activity was measured during three main conditions: baseline, stress, and recovery. Fasting blood samples were taken in the morning and saliva samples were collected at seven different time points across 24 h. Prior to intervention both groups had normal/sufficient vitamin D levels. Both groups showed a normal pattern of psychophysiological responses to the experimental stress procedure (i.e., increased psychophysiological responses from resting baseline to stress-condition, and decreased psychophysiological responses from stress-condition to recovery; all p < 0.009). Post-intervention, the Intervention group showed increased vitamin D levels (p < 0.001) and normal psychophysiological responses to the experimental stress procedure (p < 0.001). Importantly, the Control group demonstrated a classic nadir in vitamin D status post-intervention (spring) (p < 0.001) and did not show normal psychophysiological responses. Thus, physiologically the Control group showed a sustained stress response. No significant effects of vitamin D were found on serotonin and cortisol.

Intergenerational transmission of delay discounting: The mediating role of household chaos.

INTRODUCTION: Adolescence is a period when impulsive decision making may be especially vulnerable to environmental influences. Impulsive decision making is often assessed using a delay discounting paradigm, which measures the preference for smaller rewards sooner over larger rewards with a delay. Research is needed to clarify the relationship between parents' and adolescents' delay discounting and to identify related environmental processes that might facilitate the intergenerational transmission of delay discounting. The current prospective longitudinal study examined the competing mediating processes of household chaos and harsh parenting in the intergenerational transmission of delay discounting between parents and adolescents. METHODS: Participants included 167 adolescents (mean age = 14.07 years at Time 1; 53% male) and their parents (mean age = 41.98 years at Time 1; 87% female) recruited from the southeast United States. Parents' delay discounting was collected at Time 1, and adolescents' delay discounting was collected both at Time 1 and at Time 3 via a computerized delay discounting task. Parents and adolescents reported household chaos and harsh parenting at Time 2. RESULTS: A parallel mediation model indicated that parents' delay discounting at Time 1 indirectly predicted adolescents' delay discounting Time 3 residualized change scores (regressing Time 3 delay discounting onto baseline delay discounting) through household chaos but not through harsh parenting at Time 2. CONCLUSIONS: These results underline the importance of household chaos in facilitating the intergenerational transmission of delay discounting between parents and adolescents. Furthermore, our findings point to household chaos as a potential environmental target for interrupting intergenerational impulsivity.

Advances in the Assessment of Sexual Deviance.

PURPOSE OF REVIEW: This paper reviews recent research into four different approaches to the assessment of offense-related sexual deviance. RECENT FINDINGS: Two of these approaches, structured rating scales and phallometry, have a sufficient basis in research for clinical use but have undergone significant refinements in recent years. One approach, the use of cognitive tasks to indirectly assess sexual deviance, is approaching the point where it has a sound research basis for clinical use though too many promising tasks have yet to make the transition from laboratory to clinical practice. This approach has however begun to map the earlier stages of sexual response including preconscious processes. The final approach, assessment through neuroimaging, is at the earliest stage of development with research findings having yet to reach sufficient stability for clinical application. Existing assessment technologies, despite their limitations, allow professionals to assess offense-related sexual deviance. New approaches, currently being developed, potentially allow a better understanding of underlying processes and, when sufficiently mature, will be more therapeutically useful.

The Interaction Between Punishment Sensitivity and Effortful Control for Emerging Adults' Substance Use Behaviors.

BACKGROUND: Within the dual systems perspective, high reward sensitivity and low punishment sensitivity in conjunction with deficits in cognitive control may contribute to high levels of risk taking, such as substance use. OBJECTIVE: The current study examined whether the individual components of effortful control (inhibitory control, attentional control, and activation control) serve as regulators and moderate the association between reward or punishment sensitivity and substance use behaviors. METHOD: A total of 1,808 emerging adults from a university setting (Mean age = 19.48; 72% female) completed self-report measures of reward and punishment sensitivity, effortful control, and substance use. RESULTS: Findings indicated significant two-way interactions for punishment sensitivity and inhibitory control for alcohol and marijuana use. The form of these interactions revealed a significant negative association between punishment sensitivity and alcohol and marijuana use at low levels of inhibitory control. No significant interactions emerged for reward sensitivity or other components of effortful control. CONCLUSIONS: The current findings provide preliminary evidence suggesting the dual systems theorized to influence risk taking behavior interact to make joint contributions to health risk behaviors such as substance use in emerging adults.

Psychometric properties of Basic Empathy Scale among female juvenile delinquents and school youths.

Research on empathy often distinguishes between affective and cognitive empathy, but there is limited knowledge regarding the application or measurement of these two dimensions of empathy among female youth, especially forensic samples of female youth. The main aim of the present study was to examine the psychometric properties of the Basic Empathy Scale (BES) among a Portuguese sample of female youths (N=377), composed of incarcerated female juvenile offenders (n=103) and school youths (n=274). The two-factor structure of the BES obtained a good fit among the school sample, but the fit among the forensic sample was poor. Both samples demonstrated adequate psychometric properties in terms of Cronbach's alpha, omega coefficient, mean inter-item correlations, corrected item-total correlation range, and criterion validity. However, some caution is advised when using the BES with female youth involved in the juvenile justice system, particularly with incarcerated female youth.

The moderating role of emotional reactivity in the link between parental hostility and eating disorder symptoms in early adolescence.

Parent-adolescent relationship quality and affective functioning have been implicated in eating disorder development. This study examined whether maternal and paternal hostility interact to explain adolescents' eating disorder symptoms and whether parental hostility effects are more pronounced among adolescents with high emotional reactivity. A sample of 699 adolescents, ages 11-12 years, reported their parents' hostility and their own eating disorder symptoms, and parents reported adolescents' emotional reactivity. Results from structural equation modeling indicated that for emotionally reactive adolescents, paternal hostility was positively associated with eating disorder symptoms at both high and low levels of maternal hostility. In addition, eating disorder symptoms were amplified when both parents were high in hostility. Findings from this study lend support for the role of emotional reactivity in the link between parent hostility and eating disorder symptoms during adolescence.

Executive functioning and substance use in adolescence: Neurobiological and behavioral perspectives.

The current review is guided by the theoretical perspective that emphasizes the regulating role of executive functioning (Carver et al., 2009) and presents studies that elucidate the ways that executive functioning (inhibition and working memory) explain individual differences in adolescent substance use independently or by regulating the reactive system (reward and punishment sensitivity). Behavioral studies indicate that main effects of executive functioning on adolescent substance use are often nonsignificant or weak in effect sizes. In contrast, emerging evidence suggests consistent and stronger regulating effects of executive functioning over reward and punishment sensitivity. Functional neuroimaging studies reveal significant associations between executive functioning task-related hemodynamic responses and substance use with strong effect sizes. There is also direct evidence from studies testing statistical interactions of the regulating effects of EF-related brain activation, and indirect evidence in studies examining functional connectivity, temporal discounting, and reinforced control. We note key future directions and ways to address limitations in existing work.

The Moderating Role of Anxiety in the Associations of Callous-Unemotional Traits with Self-Report and Laboratory Measures of Affective and Cognitive Empathy.

In a sample of detained male adolescents (n = 107; Mean age = 15.50; SD = 1.30), we tested whether anxiety moderated the association of CU traits with self-report and computerized measures of affective (emotional reactivity) and cognitive (affective facial recognition and Theory of Mind [ToM]) empathy. Hierarchical regression analyses revealed that CU traits were negatively associated with self-reports of affective empathy and this association was not moderated by level of anxiety. Significant interactions revealed that CU traits were negatively associated with cognitive empathy (self-report) only at high levels of anxiety, whereas CU traits were positively associated with cognitive empathy on the ToM task only at low levels of anxiety. CU traits were also associated with greater fear recognition accuracy at low levels of anxiety. Implications for understanding and treating different variants of CU traits (i.e., primary and secondary) are discussed.

Intergenerational similarity in callous-unemotional traits: Contributions of hostile parenting and household chaos during adolescence.

Extant research has examined both genetic and environmental risk involved in the transmission of callous-unemotional traits in youth populations, yet no study has examined the intergenerational similarity of these traits between parents and their offspring. The current study examined whether the association between parent callous-unemotional traits and child callous-unemotional traits was mediated by parenting behavior and whether this association was moderated by household environment. Participants included 115 dyads of adolescents (48% female; Mean age=13.97) and their primary caregivers (87% female; Mean age=42.54). Measures of callous-unemotional traits, hostile parenting, and household chaos were collected from both adolescents and parents. A two group structural equation modeling revealed that hostile parenting serves as a mediating process in the association between parent and adolescent callous-unemotional traits, but only in the context of high household chaos. Our findings suggest that hostile parenting practices are a mediating process that may explain intergenerational similarity in callous-unemotional traits. Additionally, household chaos may exacerbate the effects of hostile parenting on callous-unemotional traits within adolescents, resulting in heightened vulnerability to intergenerational transmission of callous-unemotional traits.

Emotional Intelligence and Callous-Unemotional Traits in Incarcerated Adolescents.

Emotional intelligence (EI) is the ability to perceive, manage, and reason about emotions and to use this information to guide thinking and behavior adaptively. Youth with callous-unemotional (CU) traits demonstrate a variety of affective deficits, including impairment in recognition of emotion and reduced emotional responsiveness to distress or pain in others. We examined the association between ability EI and CU traits in a sample of incarcerated adolescents (n = 141) using an expert-rater device (Psychopathy Checklist Youth Version (PCL-YV; Manual for the Hare psychopathy checklist: Youth version. Multi-Health Systems, Toronto, 2003) and self-report assessments of CU traits. EI was assessed using the Mayer-Salovey-Caruso Emotional Intelligence Test-Youth Version, Research Version (MSCEIT-YV-R; MSCEIT YV: Mayer-Salovey-Caruso emotional intelligence test: Youth version, research version 1.0. Multi-Health Systems, Toronto, Ontario, 2005). Similar to findings in adult forensic populations, high levels of CU traits in incarcerated adolescents were associated with lower EI, particularly higher order EI skills. Identifying impairment on EI abilities may have important implications for emerging treatment and intervention developments for youth with high levels of CU traits.

The Social, Behavioral, and Emotional Correlates of Bullying and Victimization in a School-Based Sample.

Bullying is a prevalent problem in schools that is associated with a number of negative outcomes for both the child who bullies and his or her victims. In a community sample of 284 ethnically diverse school-children (54.2 % girls) between the ages of 9 and 14 years (M = 11.28, SD = 1.82), the current study examined whether the level of victimization moderated the association between bullying and several behavioral, social, and emotional characteristics. These characteristics were specifically chosen to integrate research on distinct developmental pathways to conduct problems with research on the characteristics shown by children who bully others. Results indicated that both bullying and victimization were independently associated with conduct problems. However, there was an interaction between bullying and victimization in the prediction of callous-unemotional (CU) traits, such that the association between bullying and CU traits was stronger for those lower on victimization. Further, bullying was positively associated with positive attitudes towards bullying and anger expression and neither of these associations were moderated by the level of victimization. In contrast, bullying was not associated with the child's perceived problems regulating anger, suggesting that children with higher levels of bullying admit to expressing anger but consider this emotional expression as being under their control.

Delay Discounting Mediates Parent-Adolescent Relationship Quality and Risky Sexual Behavior for Low Self-Control Adolescents.

Parent-adolescent relationship quality and delay discounting may play important roles in adolescents' sexual decision making processes, and levels of self-control during adolescence could act as a buffer within these factors. This longitudinal study included 219 adolescent (55 % male; mean age = 12.66 years at Wave 1; mean age = 15.10 years at Wave 2) and primary caregiver dyads. Structural equation modeling (SEM) was utilized to determine whether delay discounting mediated the association between parent-adolescent relationship quality and adolescents' risky sexual behavior and how this mediated association may differ between those with high versus low self-control. The results revealed parent-adolescent relationship quality plays a role in the development of risky sexual behavior indirectly through levels of delay discounting, but only for adolescents with low self-control. These findings could inform sex education policies and health prevention programs that address adolescent risky sexual behavior.

Annual research review: A developmental psychopathology approach to understanding callous-unemotional traits in children and adolescents with serious conduct problems.

Recent research has suggested that the presence of significant levels of callous-unemotional (CU) traits designates a clinically important and etiologically distinct subgroup of children and adolescents with serious conduct problems. Based on this research, CU traits have been included in the most recent revision of the Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5; American Psychiatric Association, 2013)--as a specifier for the diagnosis of conduct disorder. In this review, we attempt to understand CU traits within a developmental psychopathological framework. Specifically, we summarize research on the normal development of the prosocial emotions of empathy and guilt (i.e., conscience) and we illustrate how the development of CU traits can be viewed as the normal development of conscience gone awry. Furthermore, we review research on the stability of CU traits across different developmental periods and highlight factors that can influence this stability. Finally, we highlight the implications of this developmental psychopathological framework for future etiological research, for assessment and diagnostic classification, and for treatment of children with serious conduct problems.
