Perceived risk of using shared mobility services during the COVID-19 pandemic

The COVID-19 pandemic has caused our daily routines to change quickly. The pandemic provokes public fear, resulting in changes in what modes of transport people use to perform their daily activities. It is imperative for transportation authorities to properly identify the different degrees of behavioral change among various social groups. A major factor that can substantially explain individuals’ behavioral changes is the personal risk perceptions toward using shared mobility solutions. Thus, this study explores the risk that individuals perceive while using public transit and ridesharing services (as the most widespread forms of shared mobility) during the COVID-19 pandemic. To do so, we designed and implemented a multidimensional travel-behavior survey in the Chicago metropolitan area that comprises socio-demographic information and retrospective questions related to attitudes and travel behavior before and during the pandemic. Utilizing a bivariate ordered probit modeling approach to better account for the potential correlation between unobserved factors, we simultaneously modeled the perceived risk of exposure to the novel coronavirus in case of riding transit and using ridesharing services. A wide range of factors is found to be influential on the perceived risk of using shared mobility services, including the socio-demographic attributes, built environment settings, and the virus spread. Further, our results indicate that the mitigation strategies to increase the ridership of shared mobility services should be adaptive considering the spatial variations.     

Referential Intentions: A Response to Buchanan and Peet

Buchanan [2014] argues for a Gricean solution to well-known counterexamples to direct reference theories of content. Peet [2016] develops a way to change the counterexample so that it seems to speak against Buchanan's own proposal. I argue that both theorists fail to notice a significant distinction between the kinds of cases at issue. Those appearing to count against direct reference theory must be described such that speakers have false beliefs about the identity of the object to which they intend to refer, beliefs that appear relevant to the determination of what constitutes communicative success. This suggests, further, that cases of this sort do not provide a basis for robust generalizations about singular reference.     

Human machine interface design for continuous support of mode awareness during automated driving: An online simulation

In the transition towards higher levels of vehicle automation, one of the key concerns with regards to human factors is to avoid mode confusion, when drivers misinterpret the driving mode and therewith misjudge their own tasks and responsibility. To enhance mode awareness, a clear human centered Human Machine Interface (HMI) is essential. The HMI should support the driver tasks of both supervising the driving environment when needed and self-regulating their non-driving related activities (NDRAs). Such support may be provided by either presenting continuous information on automation reliability, from which the driver needs to infer what task is required, or by presenting continuous information on the currently required driving task and allowed NDRA directly. Additionally, it can be valuable to provide continuous information to support anticipation of upcoming changes in the automation mode and its associated reliability or required and allowed driver task(s). Information that could support anticipation includes the available time until a change in mode (i.e. time budget), information on the upcoming mode, and reasons for changing to the upcoming mode. The current work investigates the effects of communicating this potentially valuable information through HMI design. Participants received information from an HMI during simulated drives in a simulated car presented online (using Microsoft Teams) with an experimenter virtually accompanying and guiding each session. The HMI either communicated on automation reliability or on the driver task, and either included information supporting anticipation or did not include such information. Participants were thinking aloud during the simulated drives and reported on their experience and preferences afterwards. Anticipatory information supported understanding about upcoming changes without causing information overload or overreliance. Moreover, anticipatory information and information on automation reliability, and especially a combination of the two, best supported understandability and usability. Recommendations are provided for future work on facilitating supervision and NDRA self-regulation during automated driving through HMI design.     

Hoody,goody or buddy? How travel mode affects social perceptions in urban neighbourhoods

When travelling through a new environment people can and do make very quick judgements about the local conditions. This paper explores the idea that such judgements are affected by the travel mode they use. We hypothesise that drivers generate a more superficial impression of the things they observe than those who walk because they are exposed to less information. This prediction is based on social psychological research that demonstrates that information that becomes available in “thin slices” affects superficial judgements. A survey study (n = 644) demonstrated that perceptions of a less affluent area are indeed negatively related to more driving and positively related to more walking, but only for those who do not live there. Perceptions of a neighbouring affluent area are positively related to more driving. Two experimental studies (n = 245 and n = 91) demonstrated that explicit (but not implicit) attitudes towards a group of young people in an ambiguous social situation are more negative when they are viewed from the perspective of a car user in particular in relation to a pedestrian perspective. These findings suggest that mode use may affect communities by influencing social judgements.     

THE VALUE OF UNCERTAINTY

The author discusses some of the characteristics of Roy Schafer's contributions to psychoanalysis that he finds most valuable, such as his openness to uncertainty, his anti‐reductive view of analytic constructions, his unique formulation of the analyst's role, and his close attention to how the patient engenders particular emotional reactions in the analyst. The author also presents a clinical vignette illustrating the value of the analyst's tolerance of uncertainty in the face of the patient's push for interpretations, explanations, and reassurance.     

The Confusion of Fear and Surprise: A Developmental Study of the Perceptual-Attentional Limitation Hypothesis Using Eye Movements

The goal of the present study was to test the Perceptual-Attentional Limitation Hypothesis in children and adults by manipulating the distinctiveness between expressions and recording eye movements. Children 3–5 and 9–11 years old as well as adults were presented pairs of expressions and required to identify a target emotion. Children 3–5 years old were less accurate than those 9–11 years old and adults. All children viewed pictures longer than adults but did not spend more time attending to the relevant cues. For all participants, accuracy for the recognition of fear was lower than for surprise when the distinctive cue was in the brow only. They also took longer and spent more time in both the mouth and brow zones than when a cue was in the mouth or both areas. Adults and children 9–11 years old made more comparisons between the expressions when fear comprised a single distinctive cue in the brow than when the distinctive cue was in the mouth only or when both cues were present. Children 3–5 years old made more comparisons for brow only than both. The results of the present study extend on the Perceptual-Attentional Limitation Hypothesis showing an importance of both decoder and stimuli, and an interaction between decoder and stimuli characteristics.

Wittgenstein's critical and constructive analysis of ostensive definition is examined. Nine fundamental logico‐metaphysical errors stemming from misapprehension of ostensive definition are identified, most of which occur in the Tractatus. The Fregean holistic conception of meaning is applied to the special case of ostension. Ostensive definition is one rule among others. It is not unequivocal, it does not link language with reality, nor does it determine its own application. The role of samples in ostensive definition of perceptual properties is analysed, and the affinities between samples and Tractarian simples stressed. Samples belong to the method of representation, and not to the substance of reality. The constructive analysis is brought to bear upon the previously identified errors. Finally, a further range of problems concerning ostensive definition is raised.

Level of service delivery of public transport and mode choice in Accra,Ghana

Worsening traffic congestion and air quality has been associated with the proliferation of informal operation of private microbus and minibus in African cities. It is recognised that large buses hold the promise of relieving the growing congestion of African cities if they are managed efficiently and sustainably.It is in line with this that this study seeks to explore the reasons behind commuters’ non-preference of Metro Mass Transit (MMT) for intra-city commuting in Accra, Ghana. A revealed preference survey was administered to 134 commuters to find out the reasons behind their non-preference and their perception of the level of service (LOS) delivery of the Metro Mass Transit.The Study revealed that though Metro Mass Transit was 20% cheaper in terms of price, commuters perceived its service delivery as poor. Over-crowding of buses, non-adherence to time schedule, long in-vehicle time, perception of not getting access to seats, non-availability of bus at respondents’ origins and destinations, accessibility of alternative modes and long waiting times for buses accounted for the major reasons for non-preference.Metro Mass Transit Limited’s improvement in its service attributes especially in-vehicle time, waiting time, comfort, reliability and accessibility is a means of increasing its modal share. Adherence to these is the surest way to achieving the objective of promoting mass transit in Accra by shifting people from the use of unsustainable modes such as mini-buses and taxis to the use of efficient high capacity systems as Metro Mass Transit.     

中国人人际情感的差序格局关系:来自EAST的证据

本研究采用外部情感西蒙任务(EAST),以36名大学生为被试对自我词及亲人、熟人、陌生人三种人际关系词与积极情感和消极情感的关系进行探究,从而检验个体对自我和不同人际关系对象的情感是否存在差序格局的表现形式。结果显示,在EAST中,对自我词和亲人词作积极反应比作消极反应时间更短;对陌生人词作消极反应比作积极反应时间更短;对熟人词作积极反应和消极反应的时间差异不明显。并且,自我词的EAST效应值最大,接着依次是亲人词和熟人词;陌生人词的EAST效应值为负值。表明了在个体的认知图式中,对自我、亲人持有积极的情感,而对陌生人持有消极的情感,对熟人情感偏向不明显;且不同人际关系在情感的联结强度上表现出差序格局的形式。
