Objective: The aim of this research was to investigate whether the use of messages with negative emotional content is effective in promoting safe behavior of moped riders and how exactly these messages modulate rider behavior.

Methods: Participants received negative feedback when performing risky behaviors using a computer task. The effectiveness of this treatment was subsequently tested in a riding simulator.

Results: The results demonstrated how riders receiving negative feedback had a lower number of traffic accidents than a control group. The reduction in accidents was accompanied by a set of changes in the riding behavior. We observed a lower average speed and greater respect for speed limits. Furthermore, analysis of the steering wheel variance, throttle variance, and average braking force provided evidence for a more even and homogenous riding style. This greater abidance of traffic regulations and friendlier riding style could explain some of the causes behind the reduction in accidents.

Conclusions: The use of negative emotional feedback in driving schools or advanced rider assistance systems could enhance riding performance, making riders aware of unsafe practices and helping them to establish more accurate riding habits. Moreover, the combination of riding simulators and feedback—for example, in the training of novice riders and traffic offenders—could be an efficient tool to improve their hazard perception skills and promote safer behaviors.  相似文献

为了从控制运行的角度促进简化数学模型的应用,必须借助其它优化手段进一步提高预测精度。本文主要介绍了应用于简化数学模型的扩展卡尔曼滤波、神经网络和误差反馈系统三种优化方法以及优化后的验证结果。从验证结果来看,优化的ROM模型与ASMl模型的定性变化行为相似,基于神经网络的复合模型对PO4^3-和NOx^-的预测结果非常准确,误差反馈的优化系统模拟性能良好。  相似文献

本文以某TFT-LCD企业消防网格化实际情况为例,从网格生态构架、划分原则、信息平台建设以及培训和宣传等方面进行详细剖析,阐明在企业中如何进行消防网格化设计。通过模拟测试研究,结果表明:消防网格化的应用可以极大提高企业消防的反馈时间,但网格化在企业实际消防管理中存在非本网格员工相互推诿、拒绝配合消防工作、员工积极性不高等问题,针对问题提出措施建议,不断的优化消防网格化在企业中的应用,为企业的消防管理提供一种新思路。  相似文献

Previous research suggests that performance‐prove goal orientation is positively related to knowledge hiding. However, we argue that this effect depends on the focus of performance feedback (i.e., individual‐ and group‐focused feedback), which shapes the nature of the competitive expression of performance‐prove goal orientation (i.e., intragroup and intergroup oriented). We conducted three studies to test our theoretical model. The results of Study 1 with time‐lagged data from 128 part‐time MBA students showed that performance‐prove goal orientation was positively related to knowledge hiding when performance feedback focused more (vs. less) on individual performance but was negatively related to knowledge hiding when performance feedback focused more (vs. less) on group performance. Study 2 replicated these moderation findings in an experimental study of 210 undergraduate students. Study 3 again replicated the moderation effects using multisource data from 317 employees and their supervisors. It also included creativity as an outcome of knowledge hiding and illustrated the distal consequence of the moderation effects of individual‐ and group‐focused performance feedback. We then discussed the implications for the theory and practice of performance‐prove goal orientation and knowledge hiding.  相似文献

In recent years, due to growing environmental concern, there has been an increasing attention to product take‐back, product recovery and the re‐distribution of end‐of‐life products. Reverse logistics (RL), which refers to the distribution activities involved in product returns, has recently received much attention because many companies are using it as a strategic tool to serve their customers; and can generate good revenue. The management of return flow usually requires a specialised infrastructure with special information systems for tracking and dedicated equipment for the processing of returns. An efficient reverse distribution structure may lead to a significant return on investment as well as a significantly increased competitiveness in the market. Therefore, the time seems to be right for a systematic overview of various issues that are arising in the context of reverse distribution. The main purpose of this paper is to review the literature on RL and suggest a classification based on reverse distribution issues. The result of this research provides a better understanding of the RL concept and outlines some future directions of research on modelling and analysis.  相似文献
