How drivers hold their steering wheels when they are driving has been studied in restricted ways for many years. Here I describe the advantages (and disadvantages) of a more naturalistic way of studying this phenomenon, and present the results from two studies that observed the hand positions of motorway drivers from an elevated vehicle. In the first study I tape-recorded the data as we passed traffic on the left, and in the second I used paper and pencil to record the data as traffic passed us on the right. In both studies few drivers kept to the recommended 10-2 (or more generous 9-3) position for holding the steering wheel, and approximately one-third of them were driving with one hand on the wheel. Very few of the drivers observed (some 2%) were using mobile phones, but two were driving with no hands on the wheel. The paper concludes with some discussion of the value of this methodology for obtaining realistic data. 相似文献

This paper describes the development and implementation of qualitative behavioural criteria in order to analyse the conduct of pedestrians and vehicles when they are required to interact with each other, with particular interest to street designs with elements of shared space. The new behavioural analysis technique is developed by identifying the fundamental principles that underpin existing traffic analyses, such as traffic conflicts techniques, and adapting those to a qualitative framework that describes the mindset and rationale of road users. The technique is then applied to a case study in London, using video data from periods before and after the redevelopment of the Exhibition Road site from a conventional dual carriageway to a modern design with some elements of shared space. With the main goals being to assess the pedestrians’ confidence and the vehicles’ tolerance/patience when forced to interact with each other, behavioural trends are related to instantaneous characteristics of the vehicle flow (vehicle approach speed and traffic density). The data produced are used to develop and validate qualitative behavioural relationships for pedestrian–vehicle interactions, as well as location-specific conclusions for the Exhibition Road site. 相似文献

Adaptive behavior scales are vital in assessing children and adolescents who experience a range of disabling conditions in school settings. This article presents the results of an evaluation of the design characteristics, norming, scale characteristics, reliability and validity evidence, and bias identification studies supporting 14 norm-referenced, informant-based interviews and rating scales designed to measure adaptive behaviors. To derive these results, the manuals for each of these scales were reviewed using a standardized coding procedure, and information about each scale was double-coded by reviewers. Findings reveal that several evidence-based adaptive behavior scales are available to school psychologists. Concluding recommendations address selection and use of adaptive behavior scales as part of a comprehensive assessment, using the optimal methods of administration of adaptive behavior scales, and interpreting resultant scores that have demonstrated the highest levels of reliability and the largest body of validity evidence. 相似文献

Game-based assessment (GBA) is a specific use of educational games that employs game activities to elicit evidence for educationally valuable skills and knowledge. While this approach can provide individualized and diagnostic information about students, the design and development of assessment mechanics for a GBA is a nontrivial task. In this article, we describe the 10-step procedure that the design team of Physics Playground (formerly known as Newton's Playground) has established by adapting evidence-centered design to address unique challenges of GBA. The scaling method used for Physics Playground was Bayesian networks; thus this article describes specific actions taken for the iterative process of constructing and revising Bayesian networks in the context of the game Physics Playground. 相似文献

This study tested whether the structure of affect observed on the basis of between‐person (BP) differences is equivalent to the affect structures that organize the variability of affective states within persons (WP) over time. Further aims were to identify individual differences in the degree of divergence between the WP and BP structure and examine its association to dispositional and contextual variables (neuroticism, extraversion, well‐being and stress). In 100 daily sessions, 101 younger adults rated their mood on the Positive and Negative Affect Schedule. Variability of five negative affect items across time was so low that they were excluded from the analyses. We thus worked with a modified negative affect subscale. WP affect structures diverged reliably from the BP structure, with individual differences in the degree of divergence. Differences in the WP structural characteristics and the degree of divergence could be predicted by well‐being and stress. We conclude that BP and WP structures of affect are not equivalent and that BP and WP variation should be considered as distinct phenomena. It would be wrong, for example, to conceive of positive and negative affect as independent at the WP level, as suggested by BP findings. Yet, individual differences in WP structural characteristics are related to stable BP differences, and the degree to which individuals' affect structures diverge from the BP structure can provide important insights into intraindividual functioning.

In this paper, we present a new approach for the optimal experimental design problem of generating diagnostic choice tasks, where the respondent's decision strategy can be unambiguously deduced from the observed choice. In this new approach, we applied a genetic algorithm that creates a one‐to‐one correspondence between a set of predefined decision strategies and the alternatives of the choice task; it also manipulates the characteristics of the choice tasks. In addition, this new approach takes into account the measurement errors that can occur when the preferences of the decision makers are being measured. The proposed genetic algorithm is capable of generating diagnostic choice tasks even when the search space of possible choice tasks is very large. As proof‐of‐concept, we used this novel approach to generate respondent‐specific choice tasks with either low or high context‐based complexity that we operationalize by the similarity of alternatives and the conflict between alternatives. We find in an experiment that an increase in the similarity of the alternatives and an increase in the number of conflicts within the choice task lead to an increased use of non‐compensatory strategies and a decreased use of compensatory decision strategies. In contrast, the size of the choice tasks, measured by the number of attributes and alternatives, only weakly influences the strategy selection. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

This study investigated the mental health of people with psoriasis undergoing patient education in climate therapy. A prospective design included a baseline assessment and two follow‐ups after a 3‐week patient education program. Participants were 254 adults. Positive mental health was measured by the mental health continuum short form (0–70), and negative mental health by the emotional distress subscale (1–4) of the health education impact questionnaire. Paired‐samples t‐tests were used to evaluate changes in mental health from baseline to follow‐up. Multiple linear regression was used to analyse the ability of socio‐demographic and clinical variables and emotional distress to predict changes in positive mental health. To predict change in negative mental health we repeated the same analysis but with a change in negative mental health as a dependent variable and positive mental health as an independent variable. The results show that positive mental health and health‐related emotional distress improved significantly from before to after the intervention by 7.1 points, p < 0.001 and 0.21 points, p < 0.001) respectively. At the second follow‐up, health‐related emotional distress remained significantly improved compared with baseline levels by 0.11 points, p = 0.004. The longer participants had lived with psoriasis ( β = 146, p = 0.027), and the presence of co‐morbid health problems (β = 111, p = 0.051) the greater the improvement in the positive mental health immediately after the intervention. No predictors were identified for negative mental health. This study indicates that the promotion of positive mental health needs to be integrated into the climate therapy program, and sustained in their home context. 相似文献

There are many ways of understanding the nature of philosophical questions. One may consider their morphology, semantics, relevance, or scope. This article introduces a different approach, based on the kind of informational resources required to answer them. The result is a definition of philosophical questions as questions whose answers are in principle open to informed, rational, and honest disagreement, ultimate but not absolute, closed under further questioning, possibly constrained by empirical and logico‐mathematical resources, but requiring noetic resources to be answered. The article concludes with a discussion of some of the consequences of this definition for a conception of philosophy as the study (or “science”) of open questions, which uses conceptual design to analyse and answer them. 相似文献
