Deposition-rate dependence of granular size distribution in Cu aggregate on liquid substrate studied by atomic force microscopy

In this article, we report an atomic force microscopy study on the microstructure and the deposition-rate dependence of granular size distribution in copper (Cu) ramified aggregates on a liquid substrate. This study shows that the ramified Cu aggregates are composed of Gaussian size distribution granules, which form immediately after the Cu atoms are deposited. The interesting phenomenon is that the mean diameter Φ_m of the granules exponentially decays and approaches a stable value Φ_c with an increase in the deposition rate f. The granular mean diameter Φ_m slightly changes with the time interval Δt during which the film is kept in the vacuum chamber, owing to the large diffusion coefficient of the Cu granules on the liquid substrates. The experimental behavior strongly depends on the properties of the liquid substrate.     

Managing Coworker Assistance Through Organizational Identification

This article investigates how different sources of management support promote coworker helping behavior in organizations. We contend that senior management, managers responsible for Human Resource practices, and team leaders contribute to coworker assistance by encouraging employees to identify with the organization. Based on survey evidence drawn from nine Australian (N?=?1,349 employees) and six Chinese firms (N?=?828 employees), and using structural equation modeling, we show that organizational identification mediates the effects of perceived support from these three sources on coworker assistance. Differences in the strength of relationships between the variables are highlighted and discussed.     

Information-Hierarchical Organization of Natural Systems II: Futures of Man–Biosphere Interactions and Climate Control

The informational influence of both the vegetation and human society on climate dynamics in moderate and arid zones is revealed. The stability of the Eurasia climate during the last 2,000 years was determined by the specific structure of the Christianity-Judaism sociobiosystem. The study has also revealed the potential information-hierarchical organization of human society with a 71,874-year existence. This organization includes three world religions (Buddhism, Christianity, and Islam) as subsystems and provides both the global stability of climate processes and the conservation of evolutionary developed information-hierarchical organization of the biosphere.     

Fostering Resilience among Couples Coparenting a Young Child with Autism: An Evaluation of Together We Are Stronger

Abstract

The purpose of this study was to evaluate a 4-week caregiver training program designed to promote resilience among couples raising a child with Autism Spectrum Disorder (ASD). Seven couples with a child between the ages of 3 and 9 completed a group-based training focused on values, communication, coparenting, and managing stress. Pre-post assessment of parenting stress, dyadic satisfaction, coparenting, life satisfaction, and hope showed that although parenting stress did not decrease, significant increases were observed in dyadic cohesion, coparenting, and hope. Implications for the development of couple-focused interventions to promote resilience among parents raising a child with ASD are discussed.     

Brain functions associated with verbal working memory tasks among young males with alcohol use disorders

This study aimed to investigate the differences in brain functions during verbal working memory between individuals with alcohol use disorders (AUD) and normal controls. fMRI was used to scan brain activations associated with verbal working memory while participants performed 2-back and 0-back tasks. A total of 21 young male college students participated in the study. Eleven of those who clinically met the criteria for AUD were assigned to the AUD group, whereas ten demographically similar subjects who were social drinkers but not AUD were assigned to the normal control group. The AUD group showed less activation in bilateral frontal and precentral, left superior temporal, left superior parietal, and left cerebellar cortex during the 2-back task relative to 0-back task compared to the normal control group. In contrast, the control group showed less activation only in the right uncus than the AUD group. These results suggest that subjects with AUD present abnormality in brain functioning during verbal working memory.     

The Academic Experience of Male High School Students with ADHD

This study compared the high school academic experience of adolescents with and without childhood ADHD using data from the Pittsburgh ADHD Longitudinal Study (PALS). Participants were 326 males with childhood ADHD and 213 demographically similar males without ADHD who were recruited at the start of the follow-up study. Data were collected yearly from parents, teachers and schools. The current study used assessment points at which the participants were currently in or had recently completed grades 9, 10, 11, and 12. Results indicated that adolescents with ADHD experienced significant academic impairment in high school relative to comparison adolescents, including lower overall and main academic subject grade point averages (GPA), lower levels of class placement (e.g. remedial vs. honors), and higher rates of course failure. In addition, teacher reports indicated that adolescents with ADHD completed and turned in a significantly lower percentage of assignments and were significantly less likely to be working up to their potential. Adolescents with ADHD were also significantly more likely to be absent or tardy during the academic year, and they were over eight times more likely than adolescents without ADHD to drop out of high school. These findings demonstrate that children with ADHD continue to experience severe academic impairment into high school.     

Acceptability of Behavioral Family Therapy among Caregivers in China

In the U.S., helping the noncompliant child and parent child interaction therapy represent behavioral family therapy programs that are empirically supported for treating the conduct problems of 2- to 7-year old children. This study examined how caregivers in China would view behavioral family therapy. Caregivers in Hangzhou, China reported the perceived age of deviance for behavioral family therapy targets (e.g., noncompliance) and rated the acceptability of behavioral treatment components (e.g., timeout). Chinese caregivers agreed with European-American culture on considering noncompliance, aggression, tantrums, and negative talk deviant during the pre-school period. Overall, Chinese caregivers considered all the following nine behavioral family therapy components acceptable: contingent praise, responsive play, ignoring deviant attention seeking, authoritative instruction-giving, warnings, chair timeouts, ignoring tantrums during timeout, room backups for chair timeouts, and immediate timeouts for aggression. However, specific parental reservations were found regarding backup procedures for chair timeouts, particularly room backups. Possible treatment accommodations of behavioral family therapy for Chinese families are discussed.

Increased testosterone-to-cortisol ratio in psychopathy

Only a few studies have examined hormones in psychopathy, and results have been mixed. It has been suggested that because hormone systems are highly interconnected, it may be important to examine multiple systems simultaneously to gain a clearer picture of how hormones work together to predispose for a certain construct. In the present study, we attempt to clarify the role of the hormones cortisol and testosterone in psychopathy by examining both hormones in a community sample of 178 adults demonstrating a wide range of psychopathy scores. Results showed that psychopathy scores were associated with an increased ratio of testosterone (baseline) to cortisol responsivity to a stressor. Psychopathy was not associated with either of these measures independently or with baseline cortisol levels. These findings suggest that these highly interconnected hormone systems may work in concert to predispose to psychopathy.
