Perceived safety

感知安全
  • 文章类型: Journal Article
    这项研究调查了社交媒体和官方媒体对COVID-19信息的信任,以及这些信息的传播如何随着时间的推移通过感知安全直接和间接影响公众的福祉。
    在中国进行了两次在线调查,第一次调查(时间1,N=22,718)是在大流行爆发的早期,第二次调查(时间2,N=2,901)是在两年半后的零COVID政策封锁期。关键测量变量包括对官方媒体和社交媒体的信任,感知到COVID-19相关信息的快速传播和透明度,感知的安全性,和对大流行的情绪反应。数据分析包括描述性统计分析,独立样本t检验,皮尔逊相关性,和结构方程建模。
    对官方媒体的信任,感知到COVID-19相关信息的快速传播和透明度,感知的安全性,以及对COVID-19的积极情绪反应随着时间的推移而增加,而对社交媒体的信任和抑郁反应随着时间的推移而下降。随着时间的推移,对社交媒体和官方媒体的信任在影响公众福祉方面发挥了不同的作用。对社交媒体的信任与抑郁情绪呈正相关,而通过在时间1时感知到的安全性降低,直接或间接地与积极情绪呈负相关。然而,在时间2,对社交媒体的信任对公众福祉的负面影响在很大程度上有所下降。相比之下,对官方媒体的信任与减少抑郁反应有关,并通过两种时间感知的安全性直接和间接增加积极反应。COVID-19信息的快速传播和透明度有助于在这两种情况下增强对官方媒体的信任。
    研究结果强调了通过快速传播和信息透明度来增强公众对官方媒体的信任,在减轻COVID-19信息流行对公众福祉的负面影响方面发挥着重要作用。
    This study examined how trust in the information about COVID-19 from social media and official media as well as how the information was disseminated affect public\'s wellbeing directly and indirectly through perceived safety over time.
    Two online surveys were conducted in China, with the first survey (Time1, N = 22,718) being at the early stage of the pandemic outbreak and the second one (Time 2, N = 2,901) two and a half years later during the zero-COVID policy lockdown period. Key measured variables include trust in official media and social media, perceived rapid dissemination and transparency of COVID-19-related information, perceived safety, and emotional responses toward the pandemic. Data analysis includes descriptive statistical analysis, independent samples t-test, Pearson correlations, and structural equation modeling.
    Trust in official media, perceived rapid dissemination and transparency of COVID-19-related information, perceived safety, as well as positive emotional response toward COVID-19 increased over time, while trust in social media and depressive response decreased over time. Trust in social media and official media played different roles in affecting public\'s wellbeing over time. Trust in social media was positively associated with depressive emotions and negatively associated with positive emotion directly and indirectly through decreased perceived safety at Time 1. However, the negative effect of trust in social media on public\'s wellbeing was largely decreased at Time 2. In contrast, trust in official media was linked to reduced depressive response and increased positive response directly and indirectly through perceived safety at both times. Rapid dissemination and transparency of COVID-19 information contributed to enhanced trust in official media at both times.
    The findings highlight the important role of fostering public trust in official media through rapid dissemination and transparency of information in mitigating the negative impact of COVID-19 infodemic on public\'s wellbeing over time.

    本研究调查了SAE2级部分自动驾驶汽车的实际广泛用户,以调查驾驶员的特征(即,社会人口统计学,驾驶体验,个性),系统性能,感知的安全性,对部分自动化的信任会影响部分自动化的使用。81%的受访者表示,他们每周至少使用具有速度(ACC)和转向辅助(LKA)的自动驾驶汽车1-2次,84%和92%至少偶尔激活LKA和ACC。受访者积极评价自适应巡航控制(ACC)和车道保持辅助(LKA)的性能。ACC的评级高于LKA,并且对领头车辆和车道标记的检测的评级高于ACC和LKA的平滑控制,分别。受访者报告主要脱离接触(即,关闭)由于对系统缺乏信任和驾驶乐趣而导致的部分自动化。当他们注意到自己变得无聊或困倦时,他们很少脱离系统。结构方程模型显示,在部分自动驾驶过程中,信任对驾驶员的次要任务参与倾向有积极影响。而感知安全性的影响并不显著。关于司机的特点,我们没有发现年龄对部分自动化的感知安全性和信任有显著影响.神经质与感知的安全和信任呈负相关,而外向性不会影响感知的安全性和信任。剩下的三个人格维度“开放性”,“尽责”,在验证性因子分析中,“一致性”没有形成有效和可靠的量表,因此不能进行结构方程建模分析。未来的研究应该重新评估简短的10项量表的适用性,作为衡量大五人格特质,并调查对感知安全的影响,信任,自动化的使用和使用。
    The present study surveyed actual extensive users of SAE Level 2 partially automated cars to investigate how driver’s characteristics (i.e., socio-demographics, driving experience, personality), system performance, perceived safety, and trust in partial automation influence use of partial automation. 81% of respondents stated that they use their automated car with speed (ACC) and steering assist (LKA) at least 1–2 times a week, and 84 and 92% activate LKA and ACC at least occasionally. Respondents positively rated the performance of Adaptive Cruise Control (ACC) and Lane Keeping Assistance (LKA). ACC was rated higher than LKA and detection of lead vehicles and lane markings was rated higher than smooth control for ACC and LKA, respectively. Respondents reported to primarily disengage (i.e., turn off) partial automation due to a lack of trust in the system and when driving is fun. They rarely disengaged the system when they noticed they become bored or sleepy. Structural equation modelling revealed that trust had a positive effect on driver’s propensity for secondary task engagement during partially automated driving, while the effect of perceived safety was not significant. Regarding driver’s characteristics, we did not find a significant effect of age on perceived safety and trust in partial automation. Neuroticism negatively correlated with perceived safety and trust, while extraversion did not impact perceived safety and trust. The remaining three personality dimensions ‘openness’, ‘conscientiousness’, and ‘agreeableness’ did not form valid and reliable scales in the confirmatory factor analysis, and could thus not be subjected to the structural equation modelling analysis. Future research should re-assess the suitability of the short 10-item scale as measure of the Big-Five personality traits, and investigate the impact on perceived safety, trust, use and use of automation.

    目前的研究试图确定公众对COVID-19以外的其他疫苗和疾病的看法是否受到COVID-19大流行的影响。我们纵向检查了从COVID-19大流行之前到大流行期间是否发生了以下变化:(a)流感疫苗接种行为和意图;(b)儿童疫苗和流感疫苗的感知益处;(c)儿童疫苗和流感疫苗的感知安全性;(d)麻疹和流感的感知严重程度;(e)在两个芬兰成年人样本中对医疗保健专业人员的信任(研究1中N=205,研究2中N=197)。研究结果表明,在大流行期间,接受或想要接种流感疫苗的人比以前多。受访者还认为,流感在大流行期间更加危险,接种疫苗更安全,更有益。另一方面,对于儿童疫苗,只有感知安全性增加。最后,在其中一项研究中,在大流行期间,人们对医疗专业人员比以前更有信心。一起,这些发现暗示了COVID-19大流行对人们如何看待其他疫苗和疾病的影响。
    The current study sought to determine whether public perceptions of other vaccines and diseases than COVID-19 have been impacted by the COVID-19 pandemic. We longitudinally examined whether there had been a change from before the COVID-19 pandemic to during the pandemic in: (a) influenza vaccination behaviour and intentions; (b) the perceived benefit of childhood vaccines and influenza vaccines; (c) the perceived safety of childhood vaccines and influenza vaccines; (d) the perceived severity of measles and influenza; and (e) trust in healthcare professionals in two samples of Finnish adults (N = 205 in Study 1 and N = 197 in Study 2). The findings showed that during the pandemic, more people than before had received or wanted to receive the influenza vaccine. The respondents also believed that influenza was more dangerous during the pandemic and that vaccinations were safer and more beneficial. On the other hand, for childhood vaccines only perceived safety increased. Finally, in one of the studies, people had more confidence in medical professionals during the pandemic than they had before. Together, these findings imply a spillover of the COVID-19 pandemic on how people view other vaccines and illnesses.

    新冠肺炎给交通带来了严重的干扰和需求抑制,特别是公共交通(PT)。现在的关键挑战是恢复对PT再次安全的信任。本文调查了三个北欧城市大流行对PT安全性和压力感知的影响,利用结构方程模型分析的2018年和2020年调查数据。虽然发现大流行对总体安全和压力感知的影响不大,性别之间存在强烈的异质性,年龄和地理类别。女性认为PT安全性较低,压力较大,尤其是在大流行期间。在大流行期间,老年人减少了PT,并且没有像年轻人那样感觉到压力减轻。与奥斯陆和卑尔根相比,斯德哥尔摩的旅行者感到不那么安全,压力更大,而在卑尔根,大流行PT的使用和感知的安全性降低最少。本文讨论了跨多种出行方案对理论和政策的长期影响,这些方案考虑了模态变化和出行需求不确定性。
    COVID-19 has brought severe disruption and demand suppression to mobility, especially to public transport (PT). A key challenge now is to restore trust that PT is safe again. This paper investigates pandemic impacts on PT safety and stress perceptions in three Nordic cities, drawing on 2018 and 2020 survey data analysed in structural equation models. While finding modest pandemic effects on safety and stress perceptions overall, strong heterogeneities exist across gender, age and geographic categories. Women perceive less PT safety and more stress, especially during the pandemic. Older adults reduced PT more during the pandemic and perceived no stress reduction like younger adults. Stockholm travellers feel less safe and more stressed than in Oslo and Bergen, whilst pandemic PT use and perceived safety reductions are least in Bergen. The paper discusses the long-term implications for theory and policy across multiple mobility scenarios accounting for modal change and travel demand uncertainties.

    COVID-19大流行使餐馆实施新的安全规则。然而,由于消费者和员工的抵制,员工可能会违反这些规则来改善服务体验。本文研究了员工的亲社会安全规则打破(PSRB)如何影响消费者满意度。我们建议PSRB通过服务绩效和感知安全性的中介作用对消费者(包括请求者和旁观者)满意度具有两种竞争效应。我们在两个实验中测试了我们提出的模型,采用2(消费者角色:请求者与旁观者)×2(PSRB水平:低与高)受试者间实验设计。我们的研究结果表明,PSRB与旁观者的服务绩效评级有很强的负相关关系。PSRB伤害了请求者和旁观者的感知安全性。PSRB降低了消费者满意度,对于旁观者来说,这种关系更加牢固(与请求者)。这项研究表明,酒店组织在大流行期间和之后确保遵守安全规则的重要性。
    The COVID-19 pandemic makes restaurants implement new safety rules. However, because of consumers\' and employees\' resistance, employees may break these rules to improve the service experience. This paper examines how employees\' prosocial safety-rule-breakings (PSRB) affect consumer satisfaction. We propose that PSRB has two competing effects on consumers\' (including both requesters and bystanders) satisfaction via the mediating roles of service performance and perceived safety. We tested our proposed model in two experiments, adopting a 2 (Consumer role: Requesters vs. Bystanders) × 2 (PSRB level: Low vs. High) between-subject experimental design. Our findings suggest that PSRB has a strong negative relationship with bystanders\' service performance rating. PSRB harms both requesters\' and bystanders\' perceived safety. PSRB reduces consumer satisfaction, and the relationship is stronger for bystanders (vs. requesters). This study demonstrates the importance for hospitality organizations to ensure safety rule compliance during and after the pandemic.

    性少数男性(SMM)人群的睡眠差异受到的关注相对较少,但它们可能对解释SMM中其他健康差异至关重要。通过神经或激素途径。最近的研究表明,犯罪可能是导致睡眠差异的心理社会压力源,但这一发现是基于对犯罪的主观衡量。我们在纽约市对250个SMM进行了P18邻里研究,包括211个有足够GPS跟踪数据的人。我们使用GPS跟踪数据来定义日常路径区域活动空间,并测试了这些活动空间和受试者住宅区的暴力犯罪关联,感知到的邻里安全,用主观的睡眠来见证犯罪。使用准泊松回归,根据个人和社区的社会人口统计进行调整,我们发现,目睹更多犯罪类型的SMM在一个月内经历了明显更多的睡眠不良夜晚(RR:1.16,95CI:1.05-1.27,p值:<0.01).我们没有发现活动区或居民区的暴力犯罪率与睡眠之间有任何关联。我们的发现支持以下结论:个人接触犯罪与睡眠问题有关,并为压力和睡眠之间的途径提供了进一步的证据。邻里犯罪水平与睡眠之间缺乏联系,这表明必须有个人犯罪经验,而周围环境不足以产生影响。
    Sleep disparities in sexual minority male (SMM) populations have received relatively little attention but they may be critical to explaining other health disparities seen among SMM, via neural or hormonal pathways. Recent research suggests that crime may be a psychosocial stressor that contributes to sleep disparities but that finding has been based on subjective measures of crime. We conducted the P18 Neighborhood Study of 250 SMM in New York City, including 211 with adequate GPS tracking data. We used the GPS tracking data to define daily path area activity spaces and tested the associations of violent crime in those activity spaces and in the subject\'s residential neighborhood, perceived neighborhood safety, and witnessing crime with a subjective measure of sleep. Using quasi-Poisson regression, adjusted for individual and neighborhood socio-demographics, we found that SMM who witnessed more types of crime experienced significantly more nights of poor sleep over the course of a month (RR: 1.16, 95%CI: 1.05-1.27, p-value: < 0.01). We did not find any associations between violent crime rates in either the activity area or residential area and sleep. Our findings support the conclusion that personal exposure to crime is associated with sleep problems and provide further evidence for the pathway between stress and sleep. The lack of association between neighborhood crime levels and sleep suggests that there must be personal experience with crime and ambient presence is insufficient to produce an effect.

    在2020年初大流行开始时,许多城市已经完成或部分封锁,以最大限度地减少COVID-19的大规模传播。因此,个人旅行模式在世界各地发生了变化。这项研究探讨了达卡通勤者面临的交通方式偏好和相关困境,孟加拉国,在封锁后的时期。我们对居住在达卡的20名年轻通勤者进行了深入的半结构化采访。我们采用了演绎推理的方法,并在主题分析后对转录进行分析。研究结果表明,尽管在某些模式下认为COVID-19传播的风险很高,所有通勤者都没有轻松和灵活地切换到他们喜欢的更安全模式,通勤者在健康风险之间进行权衡,适当模式的可负担性和可用性,以及其他挑战。然而,如果采取适当的行动,国家的可持续目标仍然可以实现,例如,消除通勤者在COVID-19期间切换到可持续和安全模式时面临的挑战。
    At the start of the pandemic in early 2020, many cities went to complete or partial lockdown to minimize the mass transmission of COVID-19. Consequently, personal travel patterns have changed throughout the world. This study explores the transport mode preferences and associated dilemmas that commuters face in Dhaka, Bangladesh, in the post-lockdown period. We conducted in-depth semi-structured interviews of 20 young commuters residing in Dhaka. We followed a deductive reasoning approach, and the transcriptions were analyzed following thematic analysis. Findings suggest that despite the perceived high risk of COVID-19 transmission in certain modes, all commuters don\'t have the ease and flexibility to switch to their preferred safer mode, with commuters trading-off between health risk, affordability and availability of suitable modes, along with other challenges. However, the country\'s sustainable goals can still be achieved if proper actions, such as removing the challenges commuters face while switching to a sustainable and safe mode during COVID-19 are taken.

    Human-Robot Collaboration (HRC) has the potential for a paradigm shift in industrial production by complementing the strengths of industrial robots with human staff. However, exploring these scenarios in physical experimental settings is costly and difficult, e.g., due to safety considerations. We present a virtual reality application that allows the exploration of HRC work arrangements with autonomous robots and their effect on human behavior. Prior experimental studies conducted using this application demonstrated the benefits of augmenting an autonomous robot arm with communication channels on subjective aspects such as perceived stress. Motivated by current safety regulations that hinder HRC to expand its full potential, we explored the effects of the augmented communication on objective measures (collision rate and produced goods) within a virtual sandbox application. Explored through a safe and replicable setup, the goal was to determine whether communication channels that provide guidance and explanation on the robot can help mitigate safety hazards without interfering with the production effectiveness of both parties. This is based on the theoretical foundation that communication channels enable the robot to explain its action, helps the human collaboration partner to comprehend the current state of the shared task better, and react accordingly. Focused on the optimization of production output, reduced collision rate, and increased perception of safety, a between-subjects experimental study with two conditions (augmented communication vs non-augmented) was conducted. The results revealed a statistically significant difference in terms of production quantity output and collisions with the robot, favoring the augmented conditions. Additional statistically significant differences regarding self-reported perceived safety were found. The results of this study provide an entry point for future research regarding the augmentation of industrial robots with communication channels for safety purposes.

    To assess the association between perceived neighbourhood safety and health services use among older adults.
    The Health and Retirement Study was used to assess the association of perceived neighbourhood safety with inpatient hospital utilization, contact with a physician, home health use, and any health services utilization in the United States of America (n = 10,844). Logistic regression models were used, while controlling for a large number of potential confounders.
    The odds of any contact with a physician were greater among those who perceived their neighbourhood safety to be excellent (odds ratio (OR): 1.81, 95% confidence interval (CI): 1.20, 2.72) or very good (OR: 1.56, 95% CI: 1.04, 2.32) compared with those who perceived their neighbourhood safety as fair or poor, controlling for all model covariates. The odds of any health services utilization were greater among those who perceived their neighbourhood safety to be excellent (OR: 1.95, 95% CI: 1.26, 3.00) or very good (OR: 1.63, 95% CI: 1.06, 2.50) compared with those who perceived their neighbourhood safety as fair or poor controlling for all other model covariates. The odds of inpatient care were higher among those who perceived their neighbourhood to be excellent compared with those who compared their neighbourhood to be fair/poor (OR: 1.22, 95% CI: 1.01, 1.48). Results were not statistically significant for home health utilization.
    These analyses show a relationship between perceived neighbourhood safety and contact with a physician and any health services utilization among older adults and a weaker relationship between perceived neighbourhood safety and inpatient services. Future research should continue to examine this relationship between perceived neighbourhood safety and health services utilization among older adults.

    Pedestrian Priority Street (PPS) project, launched to encourage safer and more convenient walking by improving the inferior pedestrian environment on narrow streets without sidewalks, is based on Monderman\'s shared space concept. Similar to the shared space approach, PPS aims for mutual consideration between pedestrians and drivers and strives to create a pedestrian-friendly environment, but the project relies on a unique road surface design. Considering the two main goals of the PPS project, this study investigated how subjective safety and pedestrians\' movements differed by design types. To analyze safety perception, ordered Logit regression and post-hoc interviews were conducted with visual assessment survey using recorded VR (virtual reality) videos. Next, trace mapping and analysis were performed based on the video recordings to measure the degree of free walking. The results found that pedestrians perceived higher safety level in PPSs than in general back road. Further, the pedestrians moved more freely in the street with an integrated design. In other types, which suggested a pedestrian zone at the roadside, there was not much difference in behavior from the general back roads. Thus, the design principle of PPS, which does not set a boundary between pedestrian and vehicle area, should be observed to lead to behavioral changes in pedestrians.
