Positive School Climate as a Moderator of Violence Exposure for Colombian Adolescents

In Colombia, many adolescents have experienced violence related to the decades‐long armed conflict in the country and have witnessed or been directly victimized by violence in their communities, often related to gang activity or drug trafficking. Exposure to violence, both political and community violence, has detrimental implications for adolescent development. This study used data from 1857 Colombian adolescents in an urban setting. We aim to understand the relations between exposure to violence and adolescent outcomes, both externalizing behaviors and developmental competence, and then to understand whether school climate (i.e., safety, connectedness, services) moderates these relations. Results demonstrate that armed conflict, community violence victimization, and witnessing community violence are positively associated with externalizing behaviors, but only armed conflict is negatively associated with developmental competence. School safety, connectedness, and services moderate the relation between community violence witnessing and externalizing behaviors. School services moderates the relation between community violence victimization and developmental competence. As students perceived more positive school climate, the effects of community violence exposure on outcomes were weakened. This study identifies potential levers for intervention regarding how schools can better support violence‐affected youth through enhancements to school safety, connectedness, and services.     

The role of oxytocin in early mother-infant interactions: Variations in maternal affect attunement

The aim of the present research was to investigate the relationship between oxytocin and maternal affect attunement, as well as the role of affect attunement in the relationship between oxytocin and infant social engagement during early mother-infant interactions. Forty-three mother-infant dyads participated in the present study when infants were 4 months. They were observed during (1) a situation where no communication took place and (2) a natural interaction between mother and infant. During this procedure, three saliva samples from mothers and their infants were collected to determine their levels of oxytocin at different time points. Maternal affect attunement (maintaining attention, warm sensitivity) and infant interactive behaviors (gaze, positive, and negative affect) were coded during the natural interaction. Results indicated that overall maternal oxytocin functioning was negatively related to her warm sensitivity, while infant oxytocin reactivity together with maternal affect attunement were associated with infant positive social engagement with their mothers. Specifically, infant oxytocin reactivity was significantly related to their gazes at mother, but only for infants of highly attuned mothers. These results point to the complex role oxytocin plays in parent-infant interactions while emphasizing the need to analyze both overall oxytocin functioning as well as reactivity as different indices of human affiliative behavior.     

睡眠时间参数对学前儿童问题行为的影响:消极情绪性的调节作用

本研究以338名学前儿童为被试,采用母亲报告法探究了学前儿童睡眠时间与问题行为之间的关系,以及儿童消极情绪性的调节作用。结果发现：（1）睡眠总时长对儿童内化和外化问题行为的主效应显著,而睡眠总时长与消极情绪性对儿童内化和外化问题行为的交互作用不显著;（2）夜间睡眠比对儿童内化问题行为的主效应显著,对儿童外化问题行为的主效应不显著;夜间睡眠比与消极情绪性对儿童内化问题行为的交互作用显著,即对高消极情绪性的儿童,夜间睡眠比能够显著负向预测其内化问题行为,而对低消极情绪性的儿童,夜间睡眠比对其内化问题行为的预测并不显著;夜间睡眠比与消极情绪性对儿童外化问题行为的交互作用不显著。     

Can emotional bonding be a liability? Status striving as an intervening mechanism in affective commitment and negative work behaviors relationship

IntroductionThe dark side of affective commitment has been ignored in the past literature on organizational commitment.ObjectivesUsing the tenants of moral self-licensing theory, we examined how affective commitment can cause negative outcomes. We hypothesized that affective commitment leads to unethical pro-organizational behaviors, careerism and counter-productive work behaviors through increased urge for status striving.Methods and resultsA multi-wave and two-source data was obtained (n = 306) from employees and their peers working in the service sector of Pakistan. Employing structural equation modelling (SEM) analysis our results indicate that high levels of affective commitment might unleash status striving which further creates unethical pro-organizational behaviors, careerism and CWBs.ConclusionThe current study opens up a new side in the affective commitment literature by examining status striving as an underlying mechanism through which affective commitment reveals its deleterious consequences for employees.     

Bioinspired decision-making for a socially interactive robot

Nowadays, robots and humans coexist in real settings where robots need to interact autonomously making their own decisions. Many applications require that robots adapt their behavior to different users and remember each user’s preferences to engage them in the interaction. To this end, we propose a decision making system for social robots that drives their actions taking into account the user and the robot’s state. This system is based on bio-inspired concepts, such as motivations, drives and wellbeing, that facilitate the rise of natural behaviors to ease the acceptance of the robot by the users. The system has been designed to promote the human-robot interaction by using drives and motivations related with social aspects, such as the users’ satisfaction or the need of social interaction. Furthermore, the changes of state produced by the users’ exogenous actions have been modeled as transitional states that are considered when the next robot’s action has to be selected. Our system has been evaluated considering two different user profiles. In the proposed system, user’s preferences are considered and alter the homeostatic process that controls the decision making system. As a result, using reinforcement learning algorithms and considering the robot’s wellbeing as the reward function, the social robot Mini has learned from scratch two different policies of action, one for each user, that fit the users’ preferences. The robot learned behaviors that maximize its wellbeing as well as keep the users engaged in the interactions.

Motives to Report Stalking Cases to the Police: A Comparison Between a Large City and a Small Town in Italy

This study aimed to analyze the cases reported to police by women who were victims of stalking. The use of police offense records is well known in investigations of victims of this phenomenon as well as other violent crimes (e.g., domestic violence). The objective was to compare the 3 motives (own safety, other safety, change habits) indicated by victims in reporting the cases to police as recorded in case files. For each motive, a comparison was made of the characteristics of victims and stalkers, the nature of the relationship between the victims and stalkers, and the characteristics of the stalking campaign, the stalker’s behaviors, the consequences to the victims, and coping strategies. This information was reported by victims to police in a large city and small town in Italy. The comparison showed that victims in large cities were less prone to report stalking cases to the police than victims in small towns. Differences addressed the duration of the stalking campaign, the behaviors involved, the consequences, and the coping strategies adopted. Police forces could benefit from the results of this research in defining both training courses for police officers and prevention courses for the general population.     

Screening out accident-prone Iranian drivers: Are their at-fault accidents related to driving behavior?

To provide a scientific background in road safety domain a better understanding of human risk factor is crucial. The aims of the present study were the following: (1) developing an accident prediction model for estimating the at-fault accidents of drivers (2) controlling for the regression-to-the-mean and screening out the accident-prone drivers (3) identification of significant behavioral predictors in at-fault accident occurrences and delving into the relationship between the aberrant driving behaviors and at-fault accidents of those identified as accident-prone. A questionnaire survey compiling various measures of personality type, aberrant driving behavior, demographic and accident history information of 1762 Iranian drivers was conducted in which 1375 male and 387 female participants were of the average age of 35.6 (S.D. = 11.987). To analyze the obtained data, the generalized linear modeling (GLM) approach was taken resulting in four models with various independent variables. The results indicated that age, gender, education level, years of active driving, and especially exposure had an effect on drivers’ at-fault accidents while there was no discernible effect from income level, personality type and area of residence. In the screening procedure, 715 drivers were identified as accident-prone. Behavioral comparison analyses indicated that the lapses, errors, ordinary and aggressive violations are different for the accident-prone drivers. A comparison between the accident-prone and non-accident-prone drivers revealed that the ordinary violations have considerably higher effect than the others on at-fault accidents. Implications of the results are discussed with regard to insurance policies and education interventions.     

Bidirectional relations between different forms of prosocial behaviors and substance use among female college student athletes

Bidirectional, longitudinal relations between alcohol and marijuana use and prosocial behaviors in women college student athletes were examined. Participants were 187 female college students (M_age = 19.87 years; 91% White) who completed questionnaires on their use of marijuana and alcohol, and six forms of prosocial behaviors across 6 years (2004–2010). The findings yield overall evidence that earlier marijuana use predicted lower levels of most specific forms of prosocial behaviors for women athletes in later young adulthood. Early expressions of altruistic behaviors predicted less marijuana use in later young adulthood. Expression of public prosocial behaviors early in young adulthood predicted higher levels of hazardous drinking in late young adulthood. These novel findings have important implications for links between prosocial development and substance use in women college athletes.     

Within-person and between-people variability in personality dynamics: Knowledge structures,self-efficacy,pleasure appraisals,and the Big Five

We investigated within-person co-variations from the perspective of knowledge-and-appraisal theories of personality. Knowledge structures were idiographically assessed as personal beliefs on the relevance of personality characteristics in facilitating successful actions in interpersonal situations. Three main findings emerged. First, beliefs of situational relevance of self-defining strengths and weaknesses show additive effects in accounting for intra-individual variability in contextualized self-efficacy appraisals. Secondly, between-person variability in Extraversion moderates within-person co-variation between self-efficacy and knowledge structures. Thirdly, self-efficacy mediates the impact of knowledge structures on perceived likelihood of performing the interpersonal behaviors in the future, after controlling for rated frequency of the same behaviors in the past. Overall, the present findings suggest that within-person and between-person approaches are complementary and need to be integrated.
