This research study focused on the evaluation of an emulated in-vehicle Active Traffic and Demand Management (ATDM) system on Interstate 66 in Northern Virginia. Traditional ATDM systems rely on infrastructure-mounted variable message signs (VMS) to provide information (speed limits, lane availability, etc.) to the traveling public. By providing information about dynamic roadway conditions on an in-vehicle device, the ATDM may improve driving safety and performance by allowing drivers to remain consistently aware of forthcoming traffic conditions and roadway requirements; even when external signage is inaccessible. This study represents an initial investigation of an emulated in-vehicle ATDM to provide developers with design guidance and ensure that unintended consequences, such as distraction, do not undermine the potential benefits.Twenty younger and 20 older participants, accompanied by a member of the research team, experienced the following ATDM features on an in-vehicle device (IVD) mounted to the dashboard: (1) dynamic speed limits, (2) dynamic lane use/shoulder control, (3) High Occupancy Vehicle (HOV) restrictions, and (4) roadway information from variable message signs. The IVD was equipped with auditory and visual alerts notifying the driver when relevant visual information was updated. Research questions addressed distraction and driver behavior associated with use of the system. Qualitative and quantitative participant data was acquired from the instrumented vehicle, various questionnaires, and researcher observation.Several key findings were uncovered: (1) The IVD, as tested, did not warrant classification as a source of distraction according to the NHTSA guidelines; v2) There was a significant difference in eye-glance durations to the IVD when comparing the VMS alerts to both the speed limit and lane management alerts; and (3) The speed limit alert motivated participants to alter their speed (per survey results and participant speed data). 相似文献

Dimensions of Early Childhood Behavior Problems: Stability and Predictors of Change from 18 to 30 Months 总被引:4,自引:0,他引:4
The prevalence, structure, stability, and predictors of change in early behavior problems were examined in a population-based sample of Norwegian children at 18 and 30 months of age (N = 750). A clear factor structure involving four dimensions emerged at both assessment times: Two factors were characterized by externalizing behaviors and were labeled Social Adjustment and Overactive-Inattentive; one factor tapped internalizing problems and was labeled Emotional Adjustment; and the fourth, related to general immaturity, was labeled Regulation. Specific patterns of child and family risk factors were associated with stability and change over the two time points for each factor. Children with stable problems had the most problematic characteristics on all significant predictors, followed by children with problems at one, but not both, time points. The data suggest that it is possible to identify risk factors for stable problems at 18 months, allowing some prediction of those children whose problems will persist over early childhood. Since specific risk factors emerged for specific types of behavior problems, the results may provide some much-needed guidance to early intervention efforts. 相似文献

This paper focuses on two common misconceptions of common factors in therapy. The first misconception entails the confusion between common factors and therapeutic factors, and thus the inappropriate and misleading use of the term therapeutic common factors in various situations. The second misconception is the mixing of commonalities of different kinds and levels in proposed lists and studies of common factors. These areas are discussed and clarified, and recommendations designed to facilitate conceptual and methodological improvements relative to each misconception are offered. The selection of best levels and kinds of common factors to be studied are further explored (i.e., the study of client change events and antecedent therapist behaviors across different therapies), and specific proposals for their research are outlined. 相似文献

I first briefly review the dodo bird verdict and suggest that we should be responding to it by looking for a new way to conceptualize how therapy works. Then I describe the dominant medical or treatment model of psychotherapy and how it puts the client in the position of a dependent variable who is operated on by supposedly potent therapeutic techniques. Next I argue that the data do not fit with this model. An alternative model is that the client is the most important common factor and that it is clients' self-healing capacities which make therapy work. I then argue that therapy has two phases—the involvement phase and the learning phase—and that the involvement phase is the most important. I next review the five learning opportunities provided by therapy. Finally, I argue that a relational model of therapy focused on consultation, collaboration, and dialogue is better than a treatment model. 相似文献

The Role of Families and Care Givers as Risk and Protective Factors in Preventing Youth Violence 总被引:3,自引:0,他引:3
This paper reviews research which discusses the risk and protective functions that families and other caregivers provide in influencing the development of aggressive behavior in youth. Currently, there is an emphasis on providing violence prevention programs in the school environment, typically with little parental or caregiver involvement. By enhancing the role of families and caregivers in youth violence prevention programs, we assert that an unique opportunity exists to both address specific risk factors for violence while enhancing the protective features of the family. Relatedly, the risk literature on youth violence indicates that the most influential risk factors (i.e., the family, community, and peers) have their principle impact on youth aggression outside the school. We suggest a shift in the focus of violence prevention programming that is more inclusive of families as both a risk and protective agent. In support of this position, relevant theory and reviews of exemplary family-involved programs are offered. Challenges to involving youth caregivers are identified and recommendations for overcoming those challenges suggested. Last, recommendations for future research and public policy in the prevention of youth violence are offered. 相似文献

Although Yalom's (1995) framework of the therapeutic factors facilitating outcome in group has been accepted by group specialists, no empirically based instrument assesses all of these factors. The Therapeutic Factors Inventory (TFI), with 11 scales based on the therapeutic factors, has been designed to fill this gap. This article summarizes the development and preliminary reliability testing of the TFI. Each scale of the instrument demonstrated high internal consistency; however, one scale obtained unacceptably low test-retest reliability. Further validity testing is needed. Implications of these findings are discussed. 相似文献

The common factors debate in psychology and, more recently, marriage and family therapy is slow to erupt in pastoral care
and counselling. This article introduces the common factors debate into pastoral science by proposing the Stewardship Models
of Pastoral Ministry and Supervision. The model integrates common factors research and pastoral practice using Ricoeur’s “economy
of the gift” ethic. The model’s focus is pastoral care, counselling and supervision in congregations, a unique community context
in search of an adequate pastoral praxis. 相似文献
