A user-centred assessment of a new bicycle sharing system in Medellin

A bicycle sharing system (BSS) offers multiple benefits to a city as well as numerous challenges for effective implementation, especially if the system is connected to other modes of transportation. User-centred assessments of BSSs have been recognised as a paramount factor in transportation research, although it has received relatively little attention. This ethnographic study implemented a user experiential approach for assessing EnCicla, which is a new BSS in the city of Medellin, Colombia. A deeper understanding of users was needed for identifying the perceived journey maps; including route stages, functional likes and dislikes, affective reactions, and motivations for using the system. Findings identified not only the functional but also the affective aspects of the user experience. The 40 participants were also classified into four user groups: Lover, Civic, Grateful, and Adapted. Managerial implications involved recommendations for improving the service design and the communication and promotion strategies of the system. Limitations have to do with the specific characteristics of the sample.     

What drives corporate carsharing acceptance? A French case study

Corporate carsharing allows employees to make use of a fleet of vehicles for their business travels. It offers a means of managing vehicle fleets more optimally, bringing both economic and environmental benefits. However, this kind of use can cause concerns, and even rejection in some cases. This paper describes an online survey of 259 people in France that assessed the psychological variables determining intentions to use a corporate carsharing service. The questionnaire instantiated the dimensions of the UTAUT acceptability model. Because of the specificities of carsharing as a means of transportation, we added a dimension referring to the service’s perceived environmental friendliness. Results showed that effort expectancy (i.e., degree of ease associated with use) is the most important dimension in determining behavioral intentions about corporate carsharing. Moreover, perceived environmental friendliness had only a small effect on behavioral intentions, mediated by performance expectancy (i.e., the degree to which individuals believe that using the system will help them improve their job performance). Results are notably discussed in terms of practical recommendations to favor corporate carsharing.     

Personalising game difficulty to keep children motivated to play with a social robot: A Bayesian approach

For effective child education, playing games with a social robot should be motivating for a longer period of time. One aspect that can affect the motivation of a child is the difficulty of a game. The game should be perceived as challenging, while at the same time, the child should be confident to meet the challenge. We designed a user modelling module that adapts the difficulty of a game to the child’s skill level, in order to provide children with the optimal challenge. This module applies a Bayesian rating method that estimates the child’s skill and game item’s difficulty levels to personalise the game progress. In an experiment with 22 children (aged between 10 and 12 years old), we tested whether the personalisation leads to a higher motivation to play with the robot. Although the personalised system did not challenge the participants optimally, this study shows that the Bayesian rating system is in principle able to measure the skill and performance of children in playing a game with a robot (even without accurate estimates of the difficulty of items). We outline multiple ways in which the rating method and module can be used to further personalise and enhance the child-robot interaction, other than adapting the difficulty of games (e.g. by adapting the dialogue and feedback).     

How to improve the walking realm in a car-oriented city? (Dis)agreements between professionals

PurposeUrban environments and transport systems can enable and encourage walking, and therefore play a key role in climate action, public health, equity of access, and population wellbeing. The question, especially in cities that have been dominated by car traffic, is how? The challenge is heightened by the multidisciplinary involvements in the design, operation, and maintenance of urban infrastructure.This study examines the views of professionals from different disciplines involved in delivering walking environments in Auckland, New Zealand. The study examines agreements and disagreements regarding users’ needs, priorities, challenges, and evidence gaps for delivering quality walking environments in a car-dominated city.MethodsPrimary data were collected through an online survey (N = 28) and a focus group, both involving professionals active in urban design, road safety, transport planning, public health, urban development and strategy. Analysis involved content coding and comparing the frequency of responses across professional groups.ResultsThe results indicated a consensus on the complexity associated with providing walking environments, as well as the importance of the quality of street environments. The lack of priority given to walking, car-dominated environments, and the inability to deliver change were seen as challenges. The inputs suggested a negative chain reaction linking the low priority of walking and the lack of consensus relative to users’ experience. There appeared to be a lack of common understanding of users’ needs and experiences and a paucity of evidence on this topic.ConclusionThe findings suggest the need for urban retrofit rooted in a sound understanding of users’ needs and experiences, and walkability as a sub-system of the urban environment. Recommendations include higher interdisciplinary collaboration at the policy and practice level, reviewed delivery processes, and better-quality data.     

交往的异化:马克思《穆勒评注》中的"承认"问题

文献学的最新研究成果表明,《穆勒评注》因提出"交往的异化问题"而极大深化了整个《巴黎手稿》的理论内涵和意义。这一研究结论可从哲学史角度给予支持和佐证,表现为:在《穆勒评注》中可明显看到黑格尔发明的承认问题对马克思产生的重要影响,以及马克思对黑格尔承认论题的重大推进。马克思对人与人之间的相互承认在资本主义条件下发生的严重扭曲和异化的揭示,就突出体现在《穆勒评注》从货币和商品交换角度对"交往的异化问题"的说明中。     

Surrendering personal control to automation: Appalling or appealing?

There has been a growing interest in Autonomous Vehicle (AV) technology worldwide over the last decade. Nevertheless, various studies have noted some potential socio-psychological challenges to AV use and ownership. These challenges can be mitigated by designing AV that accounts for users’ personalities, such as their perceived control and power. The complex relationship between personal control and automation, two concepts that intuitively sound contradictory to each other, is less explored. In this study, two dimensions of personal control, the desire for control and the driver locus of control, were hypothesized to influence the attitude toward AV. The relationships were moderated by power distance, a cultural factor related to one’s sense of control. The hypotheses were tested using Structural Equation Modelling (SEM) approach via the Analysis of Moment Structures (AMOS) software. As many as 457 respondents from two sample groups, Hungarian and Indonesian drivers were gathered via an online questionnaire and compared. The results reveal that 1) the higher the desire for control, the more negative the attitude toward AV 2) the higher the external driver locus of control, the more positive the attitude toward AV 3) the more positive the attitude toward AV, the higher the intention to use AV and 4) power distance moderates the relationship between the desire for control and the attitude toward AV, such that the negative effect of the desire for control is strengthened in high power distance orientation. This study also provides theoretical contributions and managerial implications, especially to AV designers.     

Well Trained Users in a Small Theological Library?

Abstract

Few published studies report on user training in theological libraries, despite the growing complexity in the task of finding theological information. This paper is a case study of the evaluation of user training in one small theological library. Using information literacy as a framework, the researcher describes his qualitative research design, then interprets the results. He found little formal evaluation. Additionally, library staff did not put together various pieces of information about the quality of user training available to them. Based on this case, the researcher proposes five lessons for other small theological libraries.     

Factors of acceptability,acceptance and usage for non-rail autonomous public transport vehicles: A systematic literature review

Non-rail autonomous public transport vehicles have emerged over the last few years. Technical progress in automation has resulted in a growing number of autonomous shuttle pilot experiments. Although these systems are technologically feasible, determining the extent to which they correspond to users’ needs and expectations remains a major issue. In order to answer that question, we conducted a systematic review which synthesizes the literature regarding the acceptability and willingness to use this type of autonomous public transport. This literature review allowed us to identify 39 documents addressing 70 factors of acceptability, acceptance and usage of non-rail autonomous public transport vehicles. The most cited factors in the literature concern service characteristics (times, schedules, fares) and safety issues (road-safety, on-board security). Factors related to automation level, comfort and access to the vehicle feature appear to a lesser extent. Acceptance is also related to personal factors, such as socio-demographics, travel habits, and personality. This review could be of interest to designers and manufacturers of non-rail autonomous public transport vehicles, as well as policy makers, and assist with the successful implementation of autonomous public transport services which are better adapted and meet the needs of all potential users.

What and how to tell beforehand: The effect of user education on understanding,interaction and satisfaction with driving automation

The success of introducing automated driving systems to consumers will depend on an appropriate understanding and human-automation interaction with this technology. Educating users on driving automation technology bears the potential to attain these two requirements. In a driving simulator study, we investigated the effects of user education on mental models, human-automation interaction performance (i.e., time on task, error rate, experimenter rating) and satisfaction with a Human-Machine Interface (HMI) for automated driving. N = 80 participants were randomly assigned to one of three different user education conditions or to a baseline. Subsequently, they completed several driver-initiated control transitions between manual, Level 2 (L2), and Level 3 (L3) automated driving. The results revealed that user education promoted an accurate evolution of mental models for driving automation. These, in turn, facilitated interaction performance in transitions from manual to both L2 and L3 automated driving. There was no comparable influence of prior education on performance in transitions between the automation levels. Due to the performance enhancing effects of user education, no further improvements of interaction performance were observed for educated users in comparison to uneducated users. There was no effect of user education on satisfaction. The current findings emphasize the necessity to provide information about automated vehicle HMIs to first-time users to support accurate understanding and behavior. Based on the current findings, we propose conceptual approaches to teach users and derive implications for user studies on automated vehicle HMIs.
