Automated vehicles are an emerging technology that operate with differing levels of automatic control (SAE levels). The current study explored participants’ acceptance of a conditional (Level 3) automated vehicle (AV) before and after riding as a passenger for 10 min on open, public roads in uncontrolled traffic. Additionally, participants were asked to rate the riskiness (perceived risk) of a variety of vehicle maneuvers, such as turning, accelerating, and braking when approaching an intersection. We predicted that participants would report higher acceptance ratings and lower perceived risk ratings after experiencing the AV compared to pre-trip ratings. Further, we predicted that participants riding in the front-passenger seat would report higher ratings for risk compared to participants sitting in the rear-passenger or rear-driver seats. Sixty participants from South-East Queensland, Australia (aged 21–82 years; Mage = 45.78; 23 female) took part in the study. Compared to pre-trip responses, participants reported statistically higher ratings for acceptance, as well as statistically lower ratings for perceived risk with respect to specific vehicle maneuvers performed while in automated mode. Differences were detected between seats for perceived risk, but these results were less clear. Increases in acceptance and decreases in risk were also detected as the number of false hazards detected by the vehicle increased. Overall, these findings suggest that acceptance towards AVs may increase, and expectations of risk related to AV maneuvers may decrease, after participants have experienced the vehicles firsthand, on an open, public road in an uncontrolled traffic environment.  相似文献

Trust is regarded as one of the main predictors for adopting automated buses (ABs). However, theories about trust (development) in technology generally vary and an in-depths study about trust in ABs specifically is still outstanding. The present study fills this gap by presenting results from focus group interviews to trust (development) in shared automated buses prior to exposure. The objectives of this study are to contrast participants’ naïve concepts of trust with theory and to identify underlying factors influencing a-priori trust in ABs. Results show that the N = 21 focus group participants use different strategies to familiarise themselves with the new technology of ABs, e.g., comparisons with familiar technologies, fundamental tendencies to approach or avoid, additional information seeking, or anthropomorphisation. These strategies largely support existing theories on trust (development) in technology. Differences between naïve interpretations of trust and its theoretical assumptions were found in focus group debates where more control over technology limited uncertainty and led to more trust. While theories suggest control and trust to be incompatible opposites, participants see control as a way to enhance trust. We provide starting points for further theory development and expansion and stress the importance of explanations in emerging technologies for trust and acceptance building.  相似文献

AimDual career development environments (DCDEs) support athletes' effort in combining their competitive sporting careers with education or work. The characteristics of the environments may differ across cultures. The aim was to identify essential features of DCDEs based on a cross-case analysis of seven European DCDEs in Belgium, Denmark, Finland, Slovenia, Spain, Sweden, and the United Kingdom within the Erasmus+ Sport project “Ecology of Dual Career”.DesignThe study was designed as a multiple case study and based on two holistic ecological working models (Henriksen et al., 2020). The cross-case analysis included series of focus group discussions, in which two-three researchers from each partner country and four dual career (DC) support providers compared the findings across seven national cases with a primary focus on similarities rather than differences.ResultsA list of ten essential features of the DCDEs, structured into two overarching themes. (1) Holistic structure with five subthemes: Dedicated DC support team, Integration of efforts across the whole environment, A clear understanding of DC issues and support from across the environment, Role models and mentorship, and Access to expert support. (2) Shared DC philosophy also had five subthemes: A whole-person approach, An empowerment approach, Flexible DC solutions, Care of DC athlete's mental health and wellbeing, and An open and proactive approach to the development of the environment.ConclusionThe features are introduced in the manner of discussions, thus providing detailed information about the DCDEs without losing (too much) contextual information. These features can help researcher-practitioners to understand DCDEs and guide their optimization.  相似文献

追踪研究当中, 交叉滞后模型可以探究多变量之间往复式影响, 潜增长模型可以探究个体增长趋势。对两类模型进行整合, 例如同时关注往复式影响与个体增长趋势, 同时可以定义测量误差、随机截距等变异成分, 衍生出随机截距交叉滞后模型、特质-状态-误差模型、自回归潜增长模型、结构化残差潜增长模型等。以交叉滞后模型和潜增长模型分别作为基础模型, 从个体间/个体内变异分解的角度对上述各类模型梳理, 整合出此类模型的分析框架, 并拓展建立“因子结构化潜增长模型(factor latent curve model with structured reciprocals)”作为统合框架。通过实证研究(早期儿童的追踪研究-幼儿园版, ECLS-K), 建立21049名儿童的阅读和数学能力的往复式影响与增长趋势。研究发现, 分离了稳定特质的模型拟合最优。研究也对模型建模思路和模型选择提供了建议。  相似文献

基于“为学习而测评”的理念,以促进学生学习为目的,客观量化学习现状并提供诊断反馈的测评模式日益受到重视。相比于横断认识诊断测评,纵向认知诊断测评更有利于实现促进学生发展的目标。为使国内学者系统性地了解纵向认知诊断模型,首先,依据建模逻辑将已有纵向认知诊断模型划分为基于潜在转换分析的和基于高阶潜在结构模型的两类,并逐一介绍和说明两类模型的理论基础和应用情景;然后,通过模拟研究为读者呈现如何使用纵向认知诊断模型进行数据分析及如何解读相应的诊断结果。最后,提炼出四个可进一步研究的议题。  相似文献

Background/Objective: To examine the impact of a disease on a person's subjective health state, patients are often asked to assess their current health state and to retrospectively assess how healthy they were before they fell ill. The objective of this study was to test whether patients generally overestimated the quality of their pre-disease health. Method: Six samples of patients with chronic diseases (cancer patients, cardiovascular patients, and patients diagnosed with sarcoidosis, N between 197 and 1,197) were analyzed. The patients assessed their current health states and their health states at the time before diagnosis. The retrospective scores were compared with matched data from general population studies. Results: In three of the six studies, the retrospective health ratings of the patients were significantly higher than the general population norms (effect sizes between 0.24 and 0.46), two studies yielded nonsignificant effects, and in one study there was an opposite trend. The general overestimation of pre-disease health was more pronounced in older patients as compared with younger ones, and it was more pronounced when global health/quality of life was to be assessed. Conclusions: Retrospective assessments of pre-disease health states are not appropriate for assessing disease-related changes in a person's health state.  相似文献

Background/ObjectiveLong-term childhood cancer survivors (CCS) are at risk for adverse late effects. However, not all of them are well understood. The present study addressed loneliness, a previously under-researched mental health risk in cancer survivor populations. We assessed the prevalence of loneliness and its impact on psychological symptoms over time. Method: A registry-based sample of N = 633 adult long-term CCS underwent medical and psychological assessments and took part in a follow-up survey 2.5 years later. Psychological symptoms (somatic, anxiety, depression symptoms, and suicidal ideation) were measured using the Patient Health Questionnaire. We calculated linear regression models of symptoms at follow-up to investigate the impact of loneliness over time (controlling for symptoms at baseline and relevant confounders). Results: Loneliness was reported by 17.70% of CCS. In multivariate linear regression analyses, loneliness was still predictive of more severe anxiety symptoms and suicidal ideation over two years later. Loneliness did not predict somatic and depression symptoms at follow-up (which increased with age). Conclusions: Loneliness affected a significant number of CCS and was a risk factor for persistent anxiety symptoms and suicidal ideation. The extent to which young cancer patients’ re-integration into society is successful could thus have important implications for well-being in adulthood.  相似文献

Background/Objective: The aim was to evaluate the evolution of depressive symptoms and to explore the influence of physical activity (PA) practice during the home confinement due to the COVID-19 outbreak in Spain. Method: Information was collected from 595 confined participants who reported personal and contextual information, depressive symptoms and PA levels at four time points. Results: The changes in depressive symptoms were analyzed using a linear mixed model with cubic splines. Results showed a significant increase, with a significant rise between T1 and T2 (OR = 2.38, 95% CI = 1.83-3.10). It continued growing until T4 (OR = 2.93, 95% CI = 1.97-4.38). A negative relationship was observed between the increase in depressive symptoms and moderate-to-vigorous physical activity (MVPA) levels, with a significant slope up to 4 hours of MVPA per week (OR = 0.51, 95% CI = 0.29-0.90) that tended to increase until 16 hours per week of MVPA (OR = 0.41, 95% CI = 0.20-0.87). Conclusions: Results from a partition model showed that moderate intensity of PA could be enough to prevent an increase of depressive symptoms during home isolation.  相似文献

Background/Objectives: Binge Eating Disorder (BED) is often associated with obesity. In order to identify the variables that allow to better detect the presence of BED, people with overnutrition were compared with and without BED in the presence of cognitive conflicts, eating symptoms and anxious-depressive symptoms. The inclusion of cognitive conflicts had been relevant in bulimia studies but had not been investigated with respect to BED. Method: Two groups with obesity were evaluated, one without BED (OB, n = 54) and the other with BED (OB-BED, n = 48), using a social-demographic questionnaire as well as a semi-structured interview to assess BED, questionnaires (DASS-21, EDE-Q, EEQ) and the Repertory Grid Technique. Results: Overall, the OB-BED group presented more conflicts and more symptoms. The model that best differentiated between the groups included emotional eating and level of cognitive conflicts, correctly classifying 91.4% of the sample. Conclusion: These results highlight the role played by cognitive conflicts and emotional eating as differentiating elements between OB and OB-BED, with a high level of predictive accuracy.  相似文献

Background/Objective: Continuous Performance Tests (CPTs) have demonstrated validity when differentiating children with ADHD from healthy controls. However, these CPTs have limitations such as low ecological validity. New CPTs based on the use of Virtual Reality (VR) have appeared as supposedly improved methods for assessing ADHD. This study aims to compare the discriminant value of attentional variables produced by a VR CPT (Aula Nesplora) with that of variables from a traditional CPT (Test of Variables of Attention; TOVA) for identifying ADHD. Method: A total of 338 children aged between 6 and 16 years old (M = 10.84, SD = 3.01) participated in the study: 31.95% correspond to the inattentive presentation, 15.38% to the impulsive-hyperactive presentation, 22.78% to the combined presentation, and the remaining 29.88% correspond to children without ADHD. Results: Results indicated that Aula Nesplora predicts ADHD presentations better than TOVA. It also differentiates better between ADHD and non-ADHD students. Conclusions: These findings show the potential advantages of using virtual reality in ADHD assessment, as it facilitates the diagnosis of ADHD and the differentiation of its presentations in a realistic environment.  相似文献
