E-scooters are a popular intercity mode of micro-mobility, with usage steadily rising in Tel-Aviv and other cities globally. Despite the increasing e-scooter use, there exists a gap in understanding the attitudes of these vulnerable road-users toward the associated risks. This study aimed to explore e-scooters’ implicit and explicit attitudes toward the risks associated with e-scooter riding at different city locations in Israel.
Two experiments were conducted toward this goal. The preliminary study involved developing a customized Go/No-go Association Task (GNAT) tool, utilizing real-world scenarios. Forty-six participants briefly observed pictures of different e-scooter riding situations and rated their riskiness level on a Likert scale. Overall, riding on designated trails was perceived as safer than sidewalks or roads, except during phone conversations. Roads and sidewalks were perceived differently regarding riskiness level only during phone use with headphones or navigation. Neglecting to wear a helmet was perceived as risky. The GNAT tool proved valuable in assessing implicit attitudes.
In the main study, sixty-four participants completed tasks assessing implicit and explicit attitudes toward risky riding. Self-described more cautious riders demonstrated more accurate responses to risky situations under negative than under positive priming, showing more favorable norms than less cautious riders. For positive priming and risky blocks, there was a positive effect of explicit attitudes on the probability of correctly identifying risky situations, suggesting that less cautious riders demonstrate more favorable norms only under positive priming. Understanding e-scooter riders’ attitudes may contribute to producing interventions that reduce risk-taking tendencies. Implications for licensing and policy recommendations are discussed.
电动摩托车是一种流行的城际微型交通方式,在特拉维夫和全球其他城市的使用率稳步上升。尽管电动摩托车的使用量不断增加,但人们对这些易受伤害的道路使用者对相关风险的态度还缺乏了解。本研究旨在探讨以色列不同城市地点的电动摩托车使用者对骑行电动摩托车相关风险的隐性和显性态度。初步研究包括利用真实世界的场景开发一个定制的 "去/不去关联任务"(GNAT)工具。46 名参与者简要观察了不同电动摩托车骑行情况的图片,并用李克特量表对其风险程度进行了评分。总体而言,在指定的小径上骑行比在人行道或公路上骑行更安全,电话交谈时除外。只有在使用耳机或导航时,人们才会对道路和人行道的风险程度有不同的看法。忽视佩戴头盔被认为是有风险的。在主要研究中,64 名参与者完成了评估对危险骑行的内隐和外显态度的任务。自称比较谨慎的骑行者在消极引物下比在积极引物下对危险情况的反应更准确,比不那么谨慎的骑行者表现出更有利的规范。对于积极引物和风险区块,明确态度对正确识别风险情况的概率有积极影响,这表明较不谨慎的骑行者只有在积极引物下才能表现出更有利的规范。了解电动滑板车骑行者的态度可能有助于制定减少冒险倾向的干预措施。本文还讨论了许可证发放和政策建议的意义。

Background

The rapid growth of platform work has raised occupational safety and health concerns. This study investigated the psychosocial work conditions and health status of workers engaged in location-based work mediated through digital labor platforms and compared them with the general workers.

Methods

We conducted semi-structured interviews with 33 platform workers in November and December 2020, along with a cross-sectional survey of 484 platform workers in December 2021 and January 2022. The interviews explored four themes related to platform work: work motives, psychosocial work conditions, work-related health issues, and attitudes toward governmental regulations. The survey assessed psychosocial work conditions and health, and were compared with a matched sample of 913 general workers from a national survey.

Results

The in-depth interviews identified adverse work conditions among platform workers, including low skill discretion, high physical and psychological demands, experiences of workplace psychological violence, conflicts from customer-platform interactions, and platform subordinance. Motives for engaging in platform work included earning money, having better flexibility in scheduling, and utilizing it as a bridge between formal employments. Interviewees desired skill training and education for their job, as well as recognition of their employment relationship with platforms and tighter regulations on the platforms to enhance worker protection. In survey data, platform workers showed worse work conditions and health status than general workers.

Conclusion

Platform work is characterized by various types of work stress that are worse than those experienced by general workers. Policy interventions are needed to improve working conditions, clarify employment relationships, and mandate training.
背景平台工作的快速发展引发了职业安全和健康问题。本研究调查了通过数字劳动平台中介从事基于位置的工作的工人的社会心理工作条件和健康状况,并将其与普通工人进行了比较。访谈探讨了与平台工作相关的四个主题:工作动机、社会心理工作条件、与工作相关的健康问题以及对政府法规的态度。深入访谈发现了平台工作者的不利工作条件,包括技能自由裁量权低、身心要求高、工作场所心理暴力经历、客户与平台互动产生的冲突以及平台从属地位。从事平台工作的动机包括赚钱、更灵活的时间安排以及将其作为正式工作之间的桥梁。受访者希望得到工作技能培训和教育,希望他们与平台的雇佣关系得到认可,希望平台加强监管以提高对工人的保护。调查数据显示,平台工人的工作条件和健康状况比普通工人差。需要采取政策干预措施来改善工作条件、明确雇佣关系并强制开展培训。

Toxic gas leakage accidents are catastrophic and thus the subject of considerable attention among researchers, regulators, and companies. Thus, this study constructed a complex network evolution model of hazardous gas leakage accidents. It did so by analysing accident reports to then construct 10 fault trees to, in turn, construct an accident chain with causal linkages. This model comprised 67 nodes and 94 edges and effectively described the progression of such accidents from an event causality perspective. Microscopic and macroscopic analyses of the model revealed critical risk events in the network. Moreover, the comprehensive clustering coefficient (0.052), average path length (4.595), and network diameter (10) were calculated in MATLAB. These metrics were used to identify the shortest disaster paths associated with various prevention and control strategies. This study conducted deliberate attack experiments on the aforementioned network model. The findings of the study indicated the most hazardous events and pathways that are most likely to trigger accidents. These findings aligned with statistical data on accident causes, thereby providing insights for proactive prevention and effective management of gas leaks.
有毒气体泄漏事故是灾难性的,因此备受研究人员、监管机构和企业的关注。因此,本研究构建了危险气体泄漏事故的复杂网络演化模型。通过分析事故报告,构建了 10 个故障树,进而构建了一个具有因果联系的事故链。该模型由 67 个节点和 94 条边组成,从事件因果关系的角度有效地描述了此类事故的发展过程。对模型的微观和宏观分析揭示了网络中的关键风险事件。此外,还在 MATLAB 中计算了综合聚类系数(0.052)、平均路径长度(4.595)和网络直径(10)。这些指标用于识别与各种防控策略相关的最短灾难路径。本研究对上述网络模型进行了蓄意攻击实验。研究结果表明了最有可能引发事故的最危险事件和路径。这些发现与事故原因的统计数据相吻合,从而为主动预防和有效管理天然气泄漏提供了启示。

In recent years, flood disasters have intensified due to frequent extreme rainfall events worldwide. Emergency evacuation is regard as the most important response action for reducing the loss of human life in floods. However, there are still few studies on the optimal selection of emergency evacuation routes for flood disasters. This study aims to propose a novel emergency evacuation route optimization model for flood disasters using hydrodynamic model and intelligent algorithms. The hydrodynamic model is applied to simulate the flood evolution and then determine the transfer village and resettlement village, while intelligent algorithms are used to solve emergency evacuation routes between them. First, the TELEMAC-2D couples a novel fine-scale roughness assignment method are selected as the hydrodynamic model for flood evolution simulation, determining more accurate transfer and resettlement villages. Second, the Mask-RCNN image segmentation technique and Thiessen polygons are introduced to solve the missing population data in those villages, which is an important link to determine the emergency evacuation routes. Thirdly, a novel emergency evacuation route optimization model is developed combining intelligent algorithms like ant colony algorithm considering search radius, genetic algorithm coupling indexed matrix and road congestion, greatly improving the selection efficiency of flood emergency evacuation routes between transfer and resettlement villages. The research results are applicable to the emergency evacuation before and during floods, providing advance warning and process evacuation guidance.
近年来,由于全球极端降雨事件频发,洪水灾害愈演愈烈。紧急疏散被认为是减少洪灾中人员伤亡的最重要的应对措施。然而,有关洪水灾害紧急疏散路线优化选择的研究仍然很少。本研究旨在利用流体力学模型和智能算法提出一种新型洪水灾害紧急疏散路线优化模型。水动力模型用于模拟洪水演变过程,然后确定转移村和安置村,智能算法用于求解它们之间的紧急疏散路线。首先,选择 TELEMAC-2D 和一种新颖的细尺度粗糙度分配方法作为洪水演化模拟的水动力模型,确定了更准确的转移村和安置村。其次,引入 Mask-RCNN 图像分割技术和 Thiessen 多边形技术来解决这些村庄的人口数据缺失问题,这是确定紧急撤离路线的重要环节。第三,结合考虑搜索半径的蚁群算法、索引矩阵与道路拥堵耦合的遗传算法等智能算法,建立了新颖的应急疏散路线优化模型,大大提高了转移村与安置村之间洪灾应急疏散路线的选择效率。该研究成果适用于洪灾前和洪灾中的紧急疏散,提供提前预警和过程疏散指导。

A critical component of ensuring safe workplaces is training in preventing and managing violent behavior. This article examines the institutional logics underpinning such training programs, investigating their design, rationale, and impact on everyday practices within human services. Despite extensive research on the content, effects, and experiences of these training programs, there is a notable gap in understanding the rationale behind their development. This study aims to fill this gap by exploring why violence prevention and management training is structured as it is and how institutional logics affect training and practice. This research identifies seven institutional logics that shape these programs through an in-depth qualitative analysis of three Norwegian human service training programs – encompassing mental health care, child welfare services, and Norway’s national welfare agency. Some of the logics are complementary. Others are incompatible, leading to significant practical implications. Data collection included qualitative document analysis and interviews with representatives from the training communities. The study contributes to a better understanding of the factors influencing the training program design and influence, not the least, by underscoring their duality as measures of improving service delivery and ensuring safe working conditions.
确保工作场所安全的一个重要组成部分是预防和管理暴力行为的培训。本文探讨了此类培训项目背后的制度逻辑,研究了它们的设计、原理以及对人类服务机构日常实践的影响。尽管对这些培训项目的内容、效果和经验进行了广泛的研究,但在理解其发展背后的原理方面还存在明显的差距。本研究旨在通过探索暴力预防和管理培训的结构原因以及机构逻辑如何影响培训和实践来填补这一空白。本研究通过对挪威的三个人类服务培训项目(包括精神卫生保健、儿童福利服务和挪威国家福利机构)进行深入的定性分析,确定了影响这些项目的七种机构逻辑。其中一些逻辑是相辅相成的。另一些则互不相容,从而产生了重大的实际影响。数据收集包括定性文件分析和与培训社区代表的访谈。这项研究有助于更好地理解影响培训计划设计和影响的因素,尤其是通过强调其作为改善服务提供和确保安全工作条件的措施的双重性。

Effects of physical fatigue on construction safety have been widely investigated, but it fails to examine the effects when physical fatigue is combined with adverse environmental conditions. This study investigated the combined effects of physical fatigue and high temperatures on workers’ safety-related cognitive performances, including mental workload, mental fatigue, and attention. A within-subject (n = 20) experiment was designed, where subjects suffered non-fatigued and three fatigued (low, medium, and high levels) conditions, both in normothermic and hyperthermic conditions. Their cognitions were recorded using an electroencephalogram (EEG) device while performing cognitive tasks. It indicates that physical fatigue significantly impaired cognitive performances; when the heat was superimposed on physical fatigue, the negative effects of physical fatigue on cognition were magnified; the cognitive impairments would further undermine task performance. The findings would help expand the understanding of the effects of physical fatigue on construction safety, and also provide a theoretical basis for implementing safety management measures in job sites with heat exposure.
身体疲劳对建筑安全的影响已被广泛研究,但没有研究身体疲劳与不利环境条件相结合时的影响。本研究调查了身体疲劳和高温对工人与安全相关的认知能力的综合影响,包括脑力劳动负荷、精神疲劳和注意力。研究设计了一个受试者内实验(n = 20),受试者在常温和高热条件下分别处于非疲劳和三种疲劳(低度、中度和高度)状态。使用脑电图(EEG)设备记录受试者在执行认知任务时的认知情况。结果表明,身体疲劳会严重影响认知表现;当高温与身体疲劳叠加时,身体疲劳对认知的负面影响会被放大;认知障碍会进一步影响任务表现。研究结果将有助于扩大对身体疲劳对建筑安全影响的理解,也为在高温暴露的工作场所实施安全管理措施提供了理论依据。

“I probably feel slightly more invincible”: The impact of technology that discloses enforcement locations on drivers’ behaviours "我可能觉得自己更无敌了":披露执法地点的技术对司机行为的影响

There is a plethora of technology currently available that have the ability to notify individuals of traffic enforcement locations while they are driving. This technology has the potential to undermine legal deterrent efforts for preventing risky driving behaviours. However, drivers’ experiences using this technology and the trajectories through which this might interfere with deterrence for road rule violations are largely unexplored areas. As such, the present study aimed to explore two research questions: 1) what type of technology is used and how is it used, and 2) how does drivers’ use of this technology influence deterrence for road rule violations. In total, 58 Queensland licenced drivers who use technology that informs them of legal enforcement while driving participated in focus groups. To consider differences in use between ages, the sessions were conducted in three different age groups: 17–25 years, 26–49 years, and 50+ years. Reflexive thematic analysis was applied to the data, resulting in eight recognised themes. The findings highlighted that for most drivers, the primary purpose of using the technology was for navigation, while being notified of enforcement locations was a secondary purpose. In addition, the use of this technology encouraged road rule compliance for some yet was used as a strategy to avoid being caught for road rule violations for others. The findings have a number of practical and theoretical implications, demonstrating the complex interplay between technology used for enforcement notifications, its role in deterring road rule violations, and the principles of responsible innovation.
目前有大量技术能够在驾驶过程中通知个人交通执法地点。这种技术有可能会削弱法律威慑力,以防止危险驾驶行为。然而,驾驶者使用这种技术的经验以及这种技术可能干扰对违反道路规则行为的威慑力的轨迹,在很大程度上都是尚未探索的领域。因此,本研究旨在探讨两个研究问题:1)使用什么类型的技术以及如何使用;2)驾驶员使用这种技术如何影响对违反道路规则行为的威慑。共有 58 名昆士兰州持有驾驶执照的司机参加了焦点小组,他们在驾驶过程中使用了告知法律执行情况的技术。为了考虑不同年龄段使用情况的差异,会议分三个不同的年龄组进行:17-25 岁、26-49 岁和 50 岁以上。对数据进行了反思性主题分析,得出了八个公认的主题。研究结果表明,对于大多数驾驶员来说,使用该技术的主要目的是导航,而获得执法地点的通知则是次要目的。此外,对一些人来说,使用该技术是为了鼓励遵守道路规则,而对另一些人来说,使用该技术则是为了避免因违反道路规则而被抓。研究结果具有许多实践和理论意义,表明了用于执法通知的技术、其在阻止违反道路规则方面的作用以及负责任的创新原则之间复杂的相互作用。

The transition towards fully automated driving necessitates human intervention in specific scenarios, making it crucial to understand the factors influencing driver takeover performance. This meta-analysis systematically reviews 37 studies selected from an initial pool of 1945, focusing on the impact of non-driving related task (NDRT) types, takeover request (TOR) modalities, and levels of automated driving (LAD) on driver response and vehicle control during takeover events. The findings reveal that engagement in multiple NDRTs significantly delays driver response times and degrades control over vehicle dynamics, particularly in critical lateral and longitudinal maneuvers. Furthermore, multimodal TORs are more effective in eliciting timely and accurate driver responses compared to unimodal TORs, which often result in suboptimal performance. Additionally, manual driving (L0) improves emergency response but comes with a higher driving workload compared to conditional automated driving (L3) takeovers. These insights underscore the need for optimized TOR strategies and the development of advanced multimodal systems to enhance driver readiness and safety in automated driving environments.
在向全自动驾驶过渡的过程中,人类有必要在特定场景中进行干预,因此了解影响驾驶员接管性能的因素至关重要。本荟萃分析系统回顾了从最初的 1945 项研究中筛选出的 37 项研究,重点研究了非驾驶相关任务(NDRT)类型、接管请求(TOR)模式和自动驾驶水平(LAD)对接管事件中驾驶员响应和车辆控制的影响。研究结果表明,参与多种 NDRT 会显著延迟驾驶员的响应时间,并降低对车辆动态的控制,尤其是在关键的横向和纵向机动中。此外,与单模态 TOR 相比,多模态 TOR 能更有效地激发驾驶员做出及时、准确的反应,而单模态 TOR 通常会导致驾驶员表现不佳。此外,与有条件的自动驾驶(L3)接管相比,手动驾驶(L0)提高了应急响应能力,但也带来了更高的驾驶工作量。这些见解强调了优化 TOR 策略和开发先进多模态系统的必要性,以提高驾驶员在自动驾驶环境中的准备程度和安全性。

During the storage process of solid rocket motors (SRM), unintentional operations may lead to uncontrolled internal propellant combustion, which threatens to adjacent rocket motors and results in catastrophic outcomes. Consequently, the safety of storing SRM is a critical concern. In this paper, the Computational Fluid Dynamics (CFD) numerical simulation method is applied. The structure and flow parameters of the flow field are obtained using the Naiver-Stokes (N-S) control equations, the Realizable k-epsilon turbulence model, and the finite rate model. We investigate the hazardous properties of a standard storage compartment equipped with an exhaust cover and spray system in the event of an accidental jet fire. Furthermore, the safety parameters of the storage compartment are examined. The results showed that the jet flame was initially directed at the side walls, spread to the upper part, and propagated throughout the storage compartment. Using the response times and thresholds of the temperature and pressure sensors, the study determined the optimal activation time for the pressure relief port and water spray system to be 0.4 s and 0.1 s, corresponding to a spray intensity of 0.5 kg/s. The synergistic effects of the pressure relief exhaust cover and spray mechanisms could quickly reduce the temperature of the compartment below the critical threshold of 500 K, thereby preventing thermal hazards associated with propellant combustion within 10 s. The optimal location and time of entry into the storage compartment are determined based on monitoring the mass fraction of gases in the compartment while maintaining temperature and pressure safety limits. The results will provide theoretical foundations for improving secure memory design practices on SRM.
在固体火箭发动机(SRM)的储存过程中,无意的操作可能会导致内部推进剂燃烧失控,从而威胁到邻近的火箭发动机,造成灾难性后果。因此,固体火箭发动机的储存安全是一个至关重要的问题。本文采用了计算流体动力学(CFD)数值模拟方法。利用奈弗-斯托克斯(N-S)控制方程、可实现的 k-epsilon 湍流模型和有限速率模型获得了流场的结构和流动参数。我们研究了装有排气盖和喷淋系统的标准储藏室在意外喷射起火时的危险特性。此外,还考察了储藏室的安全参数。结果表明,喷射火焰最初指向侧壁,然后蔓延到上部,并扩散到整个储藏室。研究利用温度和压力传感器的响应时间和阈值,确定泄压口和喷水系统的最佳启动时间分别为 0.4 秒和 0.1 秒,对应的喷水强度为 0.5 公斤/秒。泄压排气盖和喷水机制的协同作用可迅速将舱室温度降至 500 K 临界值以下,从而在 10 秒内防止与推进剂燃烧相关的热危害。在保持温度和压力安全限制的前提下,根据对舱室内气体质量分数的监测确定进入储藏室的最佳位置和时间。研究结果将为改进 SRM 的安全存储器设计实践提供理论基础。

The most significant dangers, associated with equipment for handling/lifting loads in industrial contexts, maintenance activities and intermodal transport, are overturns, collapses and load falls. Accidents have a significant potential for injury, death and damage especially in major hazard industries due the potential release of hazardous substances. The literature review shows a lack of data to be used in performing complete risk assessments in sectors where the use of cranes could increase the risk due to the plant operability. The aim of this study is to fill this gap. The analysis of the accident and near-miss reports and the construction of a database have been the starting point of this work. The definition of the correlation accident-cause, by means of the development of bowtie analyses, supports in calculating the accidental rates and in understanding the main improvements to reduce the number of the undesired events, and to support the risk management. Focusing on major accident hazards, the top events have been identified and the bowties have been developed. By using the dataset, quantitative bowties have been provided to the risk analyst for several contexts. A case-study, which is a facility inside a refinery, has been used to quantify the effect due to crane activity inside the establishment in term of frequencies. Data processing is subject to uncertainties of various kinds, linked to technological change, the greater or lesser complexity of regulations and compliance with them. The results have been validated by using a similar dataset.
在工业、维修活动和多式联运中,与搬运/提升货物的设备有关的最大危险是倾覆、倒塌和货物坠落。事故极有可能造成人员伤亡和财产损失,特别是在重大危险行业,因为可能会释放出危险物质。文献综述显示,在使用起重机可能会因设备的可操作性而增加风险的行业中,缺乏用于进行完整风险评估的数据。本研究旨在填补这一空白。分析事故和险情报告以及建立数据库是这项工作的出发点。通过开发弓形分析法来定义相关事故原因,有助于计算事故发生率,了解主要改进措施,以减少意外事件的数量,并为风险管理提供支持。以重大事故隐患为重点,确定了主要事件,并开发了 "纽带"。通过使用数据集,为风险分析师提供了多种情况下的定量指标。案例研究是炼油厂内的一个设施,用于量化该设施内起重机活动的频率影响。数据处理会受到各种不确定性的影响,这些不确定性与技术变革、法规的复杂程度和遵守情况有关。使用类似的数据集对结果进行了验证。
