Modeling and prediction of driver preparations for making a right turn based on vehicle velocity and traffic conditions while approaching an intersection

This paper focuses on modeling and predicting the influence of a vehicle’s velocity and the relative position between a driver’s vehicle and a vehicle to the front or rear on the onset of driver preparations for making a right turn at an intersection. Repeated experiments were carried out on a public road to measure driver preparations, including releasing the accelerator pedal, moving the right foot to cover the brake pedal, and activating the turn signal, as well as to record vehicle velocity and the relative distances to the leading and following vehicles. Structural equation modeling was applied to estimate these relationships quantitatively. Two separate latent variables accounting for the interaction between the driver’s vehicle and leading or following vehicles, and the onset point where driving behavior changes from straight mode to preparation mode before a right turn, were introduced in the specification of the structural equation model. The model estimates and testing indicate that the proposed structural equation model represents well the relationship hypothesized by observational analysis: that the vehicle velocity and the traffic conditions surrounding the driver’s vehicle strongly influence the driver’s deceleration and more weakly influenced turn signal activation. The proposed structural equation model contributes to the prediction of the onset locations of covering the brake pedal and activating the turn signal based on the vehicle velocity and the relative distances to the front and rear vehicles when the accelerator pedal is released. The prediction accuracy is high compared with predictions in which the vehicle velocity and the headway or rear distances are not taken into account or predictions using a single regression model with one independent variable, namely driving speed. Finally, a possible new addition to in-vehicle navigation systems that detects unusual driver behavior by predicting the driver’s preparatory maneuvers is discussed.     

母子关系、师生关系与儿童入园第一年的问题行为

通过对102名托班幼儿的母亲和教师间隔9个月的两次测查,考察了母子关系、师生关系在儿童入园第一年的问题行为发展中的作用。结果表明：控制了儿童入园三个月时的问题行为后,(1)母子关系无法直接预测入园一年时的问题行为,师生关系冲突性可以反向预测入园一年时的退缩和违纪问题;(2)儿童性别调节了母子关系冲突性对入园一年时攻击问题的预测,即母子关系冲突性对入园一年时攻击问题的正向预测作用仅对女孩成立,对男孩则不成立;(3)师生关系亲密性调节了母子关系亲密性对入园一年时的退缩、焦虑、攻击和违纪问题的预测,即母子关系亲密性对入园一年时各种问题行为的负向预测作用仅对师生关系亲密程度高的儿童成立,对师生关系亲密程度低的儿童则不成立;对师生关系亲密程度低的儿童来说,母子关系亲密性对入园一年时的焦虑问题甚至具有正向预测作用     

BEHAVIOR ANALYSIS: THRIVING,BUT HOW ABOUT ITS FUTURE?

Behavior analysis has been thriving by continuing to make important theoretical and empirical contributions to a wide array of problems, as well as by contributing to interdisciplinary research. Applied research in behavior analysis is flourishing. Despite these positive signs there may be an erosion of support for basic research in animal learning and behavior, including behavior analysis. Increased attention by behavior analysts to fundamental problems in areas of cognition, including decision-making and language, may help behavior analysis to evolve more successfully. An experimental analysis of gambling may prove particularly fruitful.     

Associations Between Symptoms of Borderline Personality Disorder,Externalizing Disorders,and Suicide-Related Behaviors

Borderline personality disorder and externalizing disorders are associated with suicide-related behaviors. The present study examined whether symptoms of borderline personality disorder mediate the relationship between externalizing disorders and suicide-related behaviors. Diagnostic interviews were administered to 344 participants (n = 233 women). Results indicated that symptoms of antisocial personality disorder, alcohol use disorders, and drug use disorders each were significantly associated with suicide threats and self-injurious behavior in women and symptoms of antisocial personality disorder were associated with suicide attempts in women. With the exception of the association between symptoms of alcohol dependence and self-injurious behaviors, borderline personality disorder symptoms mediated or partially mediated all associations between externalizing disorders and suicide-related behaviors in women. These results highlight the importance of assessment and treatment of borderline personality disorder symptoms in individuals with externalizing disorders, particularly in the presence of suicide-related behaviors.

管理者权力距离对员工创造性观点产生与实施关系的调节作用

本研究考察了管理者的权力距离对于员工创造性观点产生与实施过程的调节作用。对170名企业员工和他们的直接主管的问卷调查结果表明：（1）管理者的权力距离对员工创造性观点的产生与实施的影响是不同的。管理者的高权力距离会抑制员工创造性观点的产生,但会促进员工创造性观点的实施。（2）管理者的高权力距离会促进员工创造性想法从产生向实施的转化。研究讨论了管理者的权力距离水平对于创新过程影响的实践意义。     

Functional analyses and treatment of precursor behavior

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe problem behavior (precursor behavior) and evaluated treatments based on the outcomes of the functional analyses of precursor behavior. Responding for all participants was differentiated during the functional analyses, and individualized treatments eliminated precursor behavior. These results suggest that functional analysis of precursor behavior may offer an alternative, indirect method to assess the operant function of severe problem behavior.     

Experimental study of the differential effects of playing versus watching violent video games on children's aggressive behavior

There is great concern about the effects of playing violent video games on aggressive behavior. The present experimental study was aimed at investigating the differential effects of actively playing vs. passively watching the same violent video game on subsequent aggressive behavior. Fifty-seven children aged 10-13 either played a violent video game (active violent condition), watched the same violent video game (passive violent condition), or played a non-violent video game (active non-violent condition). Aggression was measured through peer nominations of real-life aggressive incidents during a free play session at school. After the active participation of actually playing the violent video game, boys behaved more aggressively than did the boys in the passive game condition. For girls, game condition was not related to aggression. These findings indicate that, specifically for boys, playing a violent video game should lead to more aggression than watching television violence.     

Interactive effects of work group and organizational identification on job satisfaction and extra-role behavior

Past research has focused on the differential relationships of organizational and work group identification with attitudes and behavior. However, no systematic effort has been undertaken yet to explore interactive effects between these foci of identification. We predicted that in cases of positive overlap of identifications (i.e. high work group and organizational identification) identifications are more strongly associated with employee job satisfaction and extra-role behavior than when only one of the identifications is high—that is, the one identification augments the influence of the other. These hypotheses were tested and supported with data from two samples of bank employees (N = 358) and travel agency employees (N = 308).     

教师创造性教学行为评价量表的结构
