Post-homicidal behaviors of intrafamilial crime authors in France: An archival study

IntroductionConfessions in criminal cases range between 42 and 57%, all crimes considered. However, there is no data specifically on confessions regarding intrafamilial homicides, despite the fact that this subtype of homicide accounts for 30–40% of all homicides.ObjectiveThe purpose of the present research aims to establish the links between the sociodemographic characteristics of the perpetrators of intrafamilial murder, and their behavior and interaction with the criminal justice system after that they committed the crime (e.g., self-denunciation and confession).MethodAll cases of domestic homicide over a period of eleven years and judged in a single court of assize were analyzed (N = 44). Data regarding the type of homicide (conjugal, parricide, filicide, familicide), the sociodemographic profile of the perpetrator (sex, age, family situation, occupation, educational level) and their behaviour pre-, during- and post- the homicide were collected and analyzed.ResultsThe common intrafamilial murderer is a 36 years old man belonging to a disadvantaged socio-professional group, mostly without judicial antecedent. Moreover, confession rate is above 98% (including 41% spontaneous denunciations by the perpetrators themselves).Discussion and conclusionThis research supports earlier work on the profiles of family crime perpetrators. However, perpetrators of intrafamilial homicides confess more often than perpetrators of all other types of homicide. The results are discussed in terms of cognitive and emotional mechanisms. Suggestions for the use of such insights by investigative services are proposed.     

Measuring optimism bias among military personnel

High numbers of young military personnel die due to road traffic collisions (RTCs). Yet, there is a paucity of research related to the contributing factors (i.e., optimism bias and willingness to take risks) associated with RTCs and the examination of road safety education program tailored at reducing young military fatalities. In order to address this gap in the literature, we examined one specific road safety educational intervention tailored for the UK military personnel and investigated their attitudes towards the program, optimism bias and willingness to take risks. Measures evaluating their optimism bias, willingness to take risks and attitudes towards the program were asked after the participants attended the road safety interventions. The results revealed that young military personnel, aged 18–25, had higher optimism bias and willingness to take risks compared to older military personnel, and that this effect diminishes with age. The results provide importance evidence related to military personnel’s attitudes to risk-taking.     

Preschoolers’ distress and regulatory behaviors vary as a function of infant–mother attachment security

Children (N = 98) with higher attachment security scores, and lower resistance and avoidance scores during the Strange Situation at 16 months demonstrated somewhat more adaptive observed and mother-reported emotion regulation as preschoolers independent of maternal behavior.     

Can We Uncouple Neighborhood Disadvantage and Delinquent Behaviors? An Experimental Test of Family Resilience Guided by the Social Disorganization Theory of Delinquent Behaviors

Although the influence of neighborhood disadvantage on youth development of delinquent behavior is well established, findings from this research have yet to inform the development of family-centered prevention programming to protect youth from these erosive effects. The current paper examines the role of family integration in buffering the impact of social disadvantage in a sample of N = 298 families randomly assigned either to a control condition or to a family-based prevention program previously shown to enhance marriage and parenting. We first confirmed that neighborhood concentrated disadvantage predicted change in delinquent behaviors across the course of the study. Additionally, replicating prior work, parents participating in the Protecting Strong African American Families (ProSAAF) program, relative to those randomly assigned to the control group, significantly improved their use of effective communication strategies with each other and reduced ineffective conflict in front of youth. This resulted in a significant indirect effect of ProSAAF on change in youth delinquent behaviors. Furthermore, using mediated moderation analysis, the study tested the buffering effect of greater family integration, showing that experimentally produced change in interparental communication skills and the resulting reduction in youth exposure to parental conflict buffered the effect of neighborhood disadvantage on change in youth delinquent behaviors, supporting a mediated moderation model in which family environments buffer neighborhood effects.     

The effect of prenatal adversity on externalizing behaviors at 24 months of age in a high-risk sample: Maternal sensitivity as a moderator

The purpose of this study was to examine the moderating role of maternal sensitivity on the association between prenatal adversity and externalizing behaviors at 24 months of age in a diverse, high-risk sample. We hypothesized that among children with higher prenatal adversity, high maternal sensitivity would serve as a protective factor. Participants were 247 primarily low-income, diverse dyads. Results indicated a significant interaction effect of maternal sensitivity and prenatal adversity on externalizing problems. The association between prenatal adversity and externalizing behaviors was significant only among children who experienced low prenatal adversity, with higher maternal sensitivity associated with lower externalizing behaviors. These findings indicate that, in the absence of high prenatal risk, responsive and sensitive parenting can buffer children in an otherwise high-risk sample from the development of externalizing behaviors.     

社会排斥对网络偏差行为的影响:自我控制的中介作用和道德同一性的调节作用

本研究拟探讨社会排斥对大学生网络偏差行为的影响及其作用机制——自我控制的中介作用和道德同一性的调节作用。对769名大学生问卷调查的结果表明：（1）社会排斥与网络偏差行为呈显著正相关,与自我控制呈显著负相关;自我控制和道德同一性均与网络偏差行为呈显著负相关;（2）社会排斥对网络偏差行为具有显著的正向预测作用,且自我控制在这一关系中具有显著的中介作用;（3）社会排斥对网络偏差行为的直接预测作用以及自我控制的中介作用均受到道德同一性的调节,且这两种效应在道德同一性水平较低的群体中都更为显著。本研究不仅有助于进一步明晰网络偏差行为的影响因素及其发生机制,而且对大学生网络偏差行为的预防和干预还具有一定的实践指导价值。     

Driver behaviour and traffic accident involvement among professional urban bus drivers in China

The present research aimed to investigate specific behaviors of professional urban bus drivers in China with the revised Driver Behavior Questionnaire (DBQ), and to define the relationships among various driving behaviors (errors, positives, inattention errors, violations), background information (age, years of driving experience, mobility, etc.), self-assessment, and traffic accident. To achieve such goals, the present research designed a four-dimensional DBQ with 20 items for professional urban bus drivers in China. The KMO coefficient of the whole scale was 0.835, and Bartlett’s test was statistically significant (p < 0.000), which demonstrated strong validity of the scale and should be suitable for factor analysis. The four loading factors accounted for 58.991%. In addition, the reliability and effectiveness of the present 20-item scales were measured. The coefficient of internal consistency-Cronbach’s alpha coefficient was 0.881 and the Cronbach’s Alpha Based on Standardized Items was 0.911. This showed that driving behavior scale of professional bus drivers in China was of high reliability and validity. The analysis showed that among the four factors, positive driving behaviors were significantly associated with errors, inattention errors and violations, respectively. Errors, inattention errors and violations correlated positively with each other. This verified that the correlation coefficient of each factor was medium and high, which indicated that the scale had good difference validity. The test content of the total scale was also highly consistent with the test content of each factor, which indicated that the revised scale had good standard related validity. According to the accident prediction model, the variables that significantly affected the occurrence of traffic accidents were daily driving time, positive driving behavior, SE2 (Driving safety), SE3 (Aberrant driver behaviors). The results showed that professional bus drivers often working overtime were most likely to have accidents. The probability of traffic accidents decreased by 53% for every unit of positive driving behavior frequency of professional bus drivers. The more they felt that they had the tendency of aberrant driving behavior, the more likely they were to have traffic accidents. To summary, the present research contributed to validating and improving the DBQ for professional urban drivers in China.     

Cross-cultural differences in driver aggression,aberrant, and positive driver behaviors

The present study investigated differences in driver aggression for self and others within countries and cultural differences between driver aggression, aberrant, and positive driver behaviors across five countries (Estonia, Greece, Kosovo, Russia, and Turkey). It was predicted that drivers from these five countries differ significantly in terms of driver aggression for self and others, aberrant, and positive driver behaviors. In the study, 743 participants completed the questionnaire package, including the Driver Aggression Indicators Scale (DAIS), the short version of the Driver Behavior Questionnaire (DBQ) with items from the Positive Driver Behavior Scale, and the Demographic Information Form. Paired samples T-tests were conducted to examine the differences in driving aggression between self and others in the five countries. The results indicated that, except for Russian drivers, drivers reported that other drivers had higher driver aggression than themselves. To examine the cross-cultural differences, analysis of covariance (ANCOVA) tests were conducted for the two dimensions of the DAIS (hostile aggression and revenge, and aggressive warnings) and the three dimensions of the DBQ with items from the Positive Driver Behavior Scale (errors, violations, and positive driver behaviors). Cross-country item-based comparisons were then made for the DAIS and the DBQ. The ANCOVA results showed significant differences in both item-based and subscale comparisons. Russian drivers were significantly different from other drivers in terms of hostile aggression and the revenge subscales of the DAIS and positive driver behaviors. Turkish drivers were significantly different from other drivers in several items of the DBQ, including errors and violations. The findings suggest that culture-specific strategies might be conducted for traffic-related anger management. Furthermore, differences in errors and violations among the five countries may be due to cultural differences. Positive driver behaviors might be better promoted in countries by drawing on their distinct cultural road safety strategies.     

催产素对产后抑郁症患者母性行为的调节作用

产后抑郁症是指女性分娩后一段时间内出现的严重抑郁发作现象。研究表明, 催产素不仅参与分娩过程和正常的母性行为表达, 也在调节产后抑郁的发病及患者的母性行为中起到了重要的作用。产后抑郁症患者的情绪和认知功能受损, 这可能导致了母性行为表达质量的下降; 催产素可以通过中脑边缘多巴胺系统来调控母性行为, 作用于内侧视前区(MPOA)来激活中脑腹侧被盖区(VTA)-伏隔核(NAc)环路从而影响伏隔核内多巴胺的分泌; 催产素对产后抑郁症中母性行为的调节机制可能是通过调节五羟色胺系统的功能来发挥抗焦虑作用, 也可能是通过与其它激素的交互作用来加速母性行为的表达。未来研究进一步明确催产素在中枢神经环路中的功能差异, 以及社会支持对产后抑郁症患者催产素的使用带来的影响。
