The urban traffic system is most likely to change in the next years to a mixed traffic with human drivers, vulnerable road users, and automated vehicles. In the past, the development of external communication approaches for automated vehicles focused on scenarios where an automated vehicle communicates with either a pedestrian or a human driver. However, interactions with more than one traffic partner are more realistic. Therefore, a study with 42 participants was conducted with a multi-agent simulation in which an automated vehicle interacted simultaneously with two participants, a pedestrian and a driver of a manual vehicle. In this study, two main scenarios were investigated in order to evaluate the safety and efficiency of the interactions and to determine whether the human road users feel correctly addressed. In one scenario, the pedestrian had to cross the road in front of the automated and the manual vehicle, which were approaching from different sides. In the other, the manual vehicle had to drive through a bottleneck in front of the oncoming automated vehicle, while the pedestrian had to cross the road after both vehicles passed. The communication approach of the automated vehicle consisted of implicit signals using a speed profile and lateral offset within its lane, and explicit signals using an external human–machine interface. The results of the study show that no collisions were observed in terms of safety and no significant negative effects on efficiency were measured. However, in contrast to single agent interactions, a majority of participants felt wrongly addressed in situations where the automated vehicle signals the right-of-way to the other human road user. It can be concluded that the communication approach of the automated vehicle needs to be modified in order to address certain road users more clearly. 相似文献

Using a multiple case study approach, this ethnography examined the experiences of parents of children deemed at risk for developmental delays or disabilities who had received early intervention (EI) services (birth to age 3 years) in a large urban location in Western Canada. Participants (11 adult parents and 7 children) were drawn from six families. Methods of data collection included focus groups (FG), face‐to‐face interviews and file reviews. Member check and expert reviews were conducted throughout data collection and data analyses as part of the validation process in this ethnography. Qualitative content analyses followed by thematic analyses highlighted the implementation of family‐centred practices (FCP) as a main theme. Parents identified how EI professionals using FCP embraced collaborative practices. FCP resulted in parents leading the EI process for their children. More specifically, EI professionals shared strategies and information to support parents in gaining a deeper understanding of their children's individual developmental characteristics. Parents expressed how empowering this level of understanding was for them as they learned to articulate what were their children's needs for developmental, health and educational services. Recommendations for future research include inquiring about parents' experiences for families of diverse constellations and/or residing in smaller urban or rural communities. 相似文献

This article shows how to apply generalized additive models and generalized additive mixed models to single-case design data. These models excel at detecting the functional form between two variables (often called trend), that is, whether trend exists, and if it does, what its shape is (e.g., linear and nonlinear). In many respects, however, these models are also an ideal vehicle for analyzing single-case designs because they can consider level, trend, variability, overlap, immediacy of effect, and phase consistency that single-case design researchers examine when interpreting a functional relation. We show how these models can be implemented in a wide variety of ways to test whether treatment is effective, whether cases differ from each other, whether treatment effects vary over cases, and whether trend varies over cases. We illustrate diagnostic statistics and graphs, and we discuss overdispersion of data in detail, with examples of quasibinomial models for overdispersed data, including how to compute dispersion and quasi-AIC fit indices in generalized additive models. We show how generalized additive mixed models can be used to estimate autoregressive models and random effects and discuss the limitations of the mixed models compared to generalized additive models. We provide extensive annotated syntax for doing all these analyses in the free computer program R. 相似文献

Even though evidence-based knowledge is considered the foundation of clinical practice, many clinicians question the clinical relevance of published research. Clinicians increasingly define themselves as having an integrative stance, in contrast to the tendency for most research to be based on clearly defined psychotherapies. Qualitative single case studies make it possible to generate knowledge about what actually occurs in integrative therapy. Topic change process analysis (TCPA) is used in the analysis of brief integrative therapy conducted by a very experienced psychotherapist drawing on a complex variety of therapeutic approaches. The client was a man in his late thirties, worrying about his strong anger, particularly related to one of his children. Analysis of topic areas, topic shifts, response patterns within topics and changes in perspective made it possible to identify key processes and key patterns of the therapy which resulted in a very positive outcome for the client. Implications of these findings for practice, and future research, are discussed. 相似文献

本研究旨在通过一例抑郁症病例的52次心理治疗和效果评估说明核心人际图式改变、人格改变与症状缓解的关系。核心人际图式采用自编我的感受问卷测量,人格改变采用SWAP-200测量,症状采用OQ45.2测量。结果:核心人际图式的变化伴随着临床上可观察的人格改变、症状缓解及当事人总体功能和心理健康水平的提高。症状缓解主要体现为主观困扰的降低,但在社会功能和人际关系质量上改变不明显。结论:核心人际图式、人格障碍轮廓和症状缓解具有共变关系。 相似文献

The purpose of psychotherapy is to help clients address and overcome problems troubling them in their everyday lives. Therapy can therefore only work if clients include it in their ongoing lives to deal with their problems. Detailed, systematic research is needed on how clients do so in their everyday lives outside their sessions. A design of exploratory case studies on this topic is presented in this article. The main outcomes of such a case study on family therapy are then laid out in general terms. They highlight how treatment practices and clients’ ordinary everyday practices interact when clients change their everyday lives to overcome their troubles. They also highlight what it involves for clients to accomplish this. It is concluded that we need more research on how to understand intervention; on the interaction between interventions and clients’ conduct of their everyday life; on sessions as a particular, secluded part of clients’ ongoing everyday lives, and on how to consider therapists’ procedures and conduct of sessions accordingly. 相似文献

ObjectivesTo stimulate debate in sport and exercise psychology about the nature of mixed methods research as currently practiced and how this approach might develop in the future.DesignAn exploration of five points of controversy relating to mixed methods research.MethodA presentation of critical reflections on the following. (1) Mixing methods as a non-debate, (2) Purists, pragmatists and mixing paradigms, (3) Integrating findings and representational forms, (4) Judgment criteria and mixed methods research, and (5) Power, politics and what counts in mixed methods research.ResultsThe examples provided of mixed methods research in action indicate that a number of problematic issues regarding both process and product have been neglected.ConclusionsMixed methods research offers a number of conceptual, practical and pedagogical challenges that need to be addressed if this form of inquiry is to develop its full potential in sport and exercise psychology. 相似文献
