First-time fathers and stressors in the postpartum period

The purpose of this pilot study was to examine the everyday stressors of first-time fathers during the postpartum period and to begin the process of establishing reliability and validity for the use of the Everyday Stressors Index with a sample of first-time fathers. A convenience sample of 19 participants included first-time fathers ranging in age from 18 to 45 years and mostly living in medium-sized cities. The results indicated that factors such as a feeling of not having enough time for too many responsibilities, financial issues, and concerns about the health of the child and other family member(s) were sources of stress. However, with the exception of slight differences in the ranking, everyday stressors among first-time fathers closely resembled previously reported stressors of first-time mothers. Although the sample was small and the results nongeneralizable, these findings suggest that educational efforts by health-care professionals could beneficially be directed toward fathers as well as mothers throughout the prenatal and postpartum periods. Policy implications for nursing and new directions for future research are discussed.     

基于TPP的有机电致发光器件

Two devices with structures as indium-tin-oxide(ITO) TPP (50 nm)/tris-(8-hydroxyquinoline) aluminum(Alq3) (50 nm)/Al (150 nm) and ITO /TPP (50 nm)/lithium tera-(8-hydroxy-uinolinato)boron(LiBq4 (50 nm)/Alq3 (5 nm)/Al (150 nm) were fabricated, they showed good electroluminescent(EL) performance and TPP was proved to be a good hole transporting material.     

Corporal punishment and primary prevention of physical abuse

OBJECTIVE: To bring to the attention child maltreatment professionals the potential for primary prevention of physical abuse of ending or reducing corporal punishment by parents. METHOD: The October 1999 special issue of Child Abuse & Neglect on "A National Call to Action: Working Toward the Elimination of Child Maltreatment" was reviewed in relation to coverage of corporal punishment by parents. RESULTS: Corporal punishment was not mentioned in any of the nine articles. CONCLUSIONS: The combination of research showing that corporal punishment is a major risk factor for physical abuse and research showing the wide prevalence and chronicity of corporal punishment suggests that the "National Call For Action" should include steps to end use of corporal punishment as a mode of discipline.     

Reevaluating canine perspective-taking behavior

Udell, Dorey, and Wynne (2011) demonstrated that both domesticated and nondomesticated canids—specifically, gray wolves—have the capacity to succeed on perspective-taking tasks, suggesting that dogs’ ability to respond to the human attentional state is not a by-product of domestication alone. Furthermore, not all dogs were successful on the task. Instead, the occluder type used was a strong predictor of performance, indicating the important role of environment and experience for tasks of this type. Here, we address several commentaries reflecting on the methods and design of that study, as well as the interpretation of the results. We also discuss the positive shift toward more interactive approaches in the field of canine behavior and cognition. Finally, we question the functionality of describing canine social behavior in terms of theory of mind.     

Can your dog read your mind?: Understanding the causes of canine perspective taking

Prior studies have documented the domestic dog’s (Canis lupus familiaris) sensitivity to human attentional state, including a tendency to preferentially beg for food from attentive individuals and an ability to selectively perform forbidden behaviors when humans are not looking. Due to the success of dogs on perspective-taking tasks, some have hypothesized that domestic dogs may have theory of mind, or the ability to infer what other individuals know. Here we provide the first evidence that nondomesticated canids, grey wolves (Canis lupus), are also sensitive to human attentional state under some conditions. We also demonstrate that dogs do not display an undifferentiated sensitivity to all visual cues of attentional state. Rather, dogs are more sensitive to stimuli encountered in their home environment. Some dogs perform poorly on perspective-taking tasks. These findings have important implications for the interpretation of research designed to understand complex social cognition across species.     

Construction Direction and Development Path of Digital Educational Resources in the Era of New Educational Infrastructure Construction

Digital educational resources have become essential elements of modern educational public services. China’s national program on new educational infrastructure construction has proposed to take new infrastructure construction of digital educational resources as one of the critical tasks. This paper aims to provide a theoretical basis for advancing the reform and development of digital educational resources in the new era. It classifies the current development and realistic challenges of China’s digital educational resources, and summaries and interprets the directions of the three construction projects of new type resources and tools, the resource supply system, and the resource supervisory system. It depicts the prospect of digital educational resource construction in the intelligent era in the combination of the strategic layout of the policies on new educational infrastructure construction. It also discusses such key technologies supporting new infrastructure construction of digital educational resources as multimodal learning analytics, disciplinary knowledge graphs, machine learning, and blockchain. It finally proposes a specific development path for new infrastructure construction of digital educational resources.     

Predicting long-term outcomes for women sexually abused in childhood: contribution of abuse severity versus family environment

OBJECTIVE: Child sexual abuse (CSA) has been associated with adverse adult psychosocial outcomes, although some reports describe minimal long-term effects. The search for explanations for the heterogeneous outcomes in women with CSA has led to an examination of a range of CSA-related factors, from the severity of individual CSA incidents to the childhood family environment. This study compares three factors for predicting adult outcomes: a multidimensional CSA Severity Scale, the presence or absence of CSA, and family environment. METHODS: The effect of CSA on adult outcomes was examined among 290 community-dwelling women raised in intact families. Standardized measures and a focused interview were used to collect data, with siblings as collateral informants. RESULTS: Comparison of a multidimensional CSA Severity Scale to a dichotomous measure of the presence or absence of CSA showed that the Severity Scale did not have greater predictive value for adult outcomes than the dichotomous measure, nor was it as parsimonious. Childhood family environment scales added significantly to the predictive ability of the dichotomous measure. CONCLUSION: The specific characteristics of a CSA experience may be less important than the occurrence of CSA and the family environment of women for predicting long-term outcomes.     

Behavioral problems among children whose mothers are abused by an intimate partner

OBJECTIVES: To determine the association between children's exposure to maternal intimate partner violence (IPV) and behavior problems as measured by the parent report version of the Child Behavior Checklist (CBCL). METHODS: The study population was comprised of 167 2- to 17-year-old children of Seattle women with police-reported or court-reported intimate partner abuse. The CBCL normative population served as the comparison group. Risk of behavior problems was calculated among the exposed children, in the presence and absence of a history of reported child maltreatment, relative to the normative population. Multiple logistic regression served as the primary method of analysis. RESULTS: Children exposed to maternal IPV were more likely to have borderline to clinical level scores on externalizing (i.e., aggressive, delinquent) behavior (RR=1.6, 95% CI: 1.2, 2.1) and total behavioral problems (RR=1.4, 95% CI: 1.1, 1.9) compared to the CBCL normative sample after adjusting for age and sex. Children who were exposed to maternal IPV and were victims of child maltreatment were more likely to receive borderline to clinical level scores on internalizing (i.e., anxious, depressed) behaviors (RR=2.6, 95% CI: 1.5, 3.6), externalizing (i.e., aggressive, delinquent) behaviors (RR=3.0, 95% CI: 1.9, 4.0) and total behavioral problems (RR=2.1, 95% CI: 1.2, 3.2) compared to the CBCL normative sample after adjusting for age and sex. CONCLUSIONS: Exposure to maternal IPV is significantly associated with child behavioral problems both in the presence and absence of co-occurring child maltreatment. Appropriate attention to the mental health of children living in households with IPV is needed.     

Efficacy Perceptions of Preservice and Inservice Teachers in China: Insights Concerning Culture and Measurement

This study comprises the second stage of a research program in which sense of efficacy for teaching (SET) was investigated in Chinese mainland preservice and inservice teachers (PSTs and ISTs, respectively). Scores on SET were calculated and described, and SET comparisons were made between and within PSTs and ISTs. Relative to PSTs, ISTs had higher SET; within both the PSTs and IST samples there were no gender differences; but among ISTs there were some associations of SET with years of teaching, teacher roles, and whether the schools were categorized as advanced or standard. Tentative comparisons are drawn concerning SET in Chinese and Western contexts, and recommendations are made concerning effective measurement of teacher sense of efficacy in China and elsewhere.
