A number of countries allow bicyclists to perform a right turn on red (RTOR) at some specific intersections to promote cycling by reducing the required physical effort and trip time. Implementation of a rule that allows a RTOR for bicyclists at some intersections could lead not only to local effects at those intersections where the rule actually applies, but also to supralocal effects. Using an experimental survey approach, this study explores whether a so-called ‘spillover effect’ of the rule can be expected. This effect would imply that allowing bicyclists to turn right on red at some intersections causes them to also turn right on red more often at intersections where RTOR for bicyclists is not allowed.The answers from 768 respondents indicate that respondents with a high awareness of the existence of a RTOR rule for bicyclists (experimental group) turn right on red significantly more often at intersections where RTOR for bicyclists is not permitted than respondents with a low awareness of the rule (control group). This indicates that implementation of the RTOR rule for bicyclists can indeed lead to an increase in red light running at other intersections. This might lead to safety issues at intersections where RTOR for bicyclists is not permitted, since road authorities could have decided not to allow RTOR for bicyclists at these intersections for safety reasons.The study also finds that men, young people and people who generally perform more risky cycling behaviours have a higher tendency to perform non-permitted RTOR. These findings are in line with existing literature. 相似文献

The purpose of this paper was to investigate how individual differences in glance strategy could impact the glance performance test defined in the NHTSA visual manual distraction guidelines. Better understanding of the test procedure could help development of new technology for safe driving. A custom in-vehicle information system was developed and assessed in a driving simulator by eighteen participants. The interfaces were designed according to recommendations in the NHTSA guidelines and contained manual radio-tuning tasks, sound settings tasks and six letter spelling tasks. Two of the six tested interfaces fully complied with the test. In addition, clear individual differences in glance strategy were found among the participants. Four individual glance strategies were identified. Two of these, long glancers and frequent glancers, highly affected the outcome of the compliance test. Participants belonging to the long glancers and the frequent glancers categories were identified as statistical outliers in many test cases. For example, if the individual values of these participants were replaced with sample mean, the number of complying interfaces would increase to five out of six, which is more in line with expectations for these interfaces. The results of this study show that individual variations in glance strategy exist. Also, these individual variations seem to have a non- negligible influence on the result when performance-testing of in-vehicle interfaces is done according to the NTHSA guidelines. 相似文献

South Africa is regularly identified in international literature as one of the countries with the highest number of traffic deaths per capita. Of these, around one third are pedestrians. Freeways constitute one of the highest risk locations for pedestrians – in most developed countries pedestrians are not seen in such locations, but for many South African pedestrians freeways are a regular part of their commute. Walking alongside and crossing of freeways are extremely common – and deaths associated with such activity also tragically so. Over the past four years in the Cape Town area alone there have been 413 pedestrian crashes causing 139 pedestrian deaths on freeways, as well as an unrecorded number of serious injuries.While pedestrian crossing behaviour has been extensively researched in many parts of the world, almost none has so far been carried out in the context of freeways. Little is known about pedestrian crossing decisions in locations where the stakes are so high.Following a study using traffic cameras associated with the Freeway Management System to measure the frequency and location of pedestrians crossing freeways, this article reports on surveys into crossing decisions of pedestrians on Cape Town’s freeways. Two successive surveys were conducted with pedestrians on or alongside the freeway. These included pedestrians who crossed using footbridges, and pedestrians who crossed at grade.In the analysis it was clear that while some of the traditional factors such as time saving and convenience were considered, far more important to pedestrians were issues of safety. Safety from fast-moving vehicles was one factor, while safety from criminals was a second and often conflicting factor which affected crossing choices. Crossing at grade was partly described in terms of utility maximisation (time and distance saving) but it was also, for many, one way of avoiding becoming a victim of crime. In terms of their perceptions of being involved in crashes, at-grade crossers reflected an astute awareness of the risks that they face. Many pedestrians articulated the belief that their choice of crossing was constrained by lack of alternatives. Until public transport and safe crossing locations are provided for these pedestrians it is clear that many will continue to cross dangerous roads, in full awareness of the risks they face. 相似文献

Numerous studies have shown that perceived organizational support has positive consequences on both employees and organizations. However, no study has examined the causal relationship between perceived organizational support and proactive behaviour directed towards the organization and few studies have identified potential mechanisms underlying this relationship. We first investigated the direction of causality between perceived organizational support and proactive behaviour, and hypothesized that perceived organizational support leads to proactive behaviour directed towards the organization. Second, based on social exchange and motivational perspectives, we examined two potential mechanisms underlying this relationship, i.e., felt obligation and work engagement. Employees from a Belgian Federal Public Service were invited to take part in a three-wave longitudinal survey. Using a cross-lagged panel design, our results (N = 1963) revealed that Time 2 perceived organizational support was positively related to Time 3 proactive behaviour towards the organization, whereas the reverse was not true. Additionally, our results (N = 1293) showed that Time 2 felt obligation and Time 2 work engagement mediated the positive relationship between Time 1 perceived organizational support and Time 3 proactive behaviour directed towards the organization. 相似文献

The effects of emotional labour, that is, managing one’s emotions for work, not only predict a range of intrapersonal and organizational outcomes but can also spillover to affect non-work relationships. Despite this, relatively little is known about whether the performance of surface acting affects behaviours towards more proximal organizational members, how this occurs, and the role of supportive relationships in influencing this relationship. In this article, we examine the relationships between surface acting, state positive and negative affect, and co-worker support on co-worker-directed interpersonal behaviours in the workplace. Survey data collected at multiple time points suggest a moderated mediation model, in which surface acting interacts with co-worker support to influence employees’ voluntary behaviours through state affect. Specifically, our findings suggest that surface acting increases subsequent engagement in deviance behaviours by increasing the experience of negative affective states, especially when co-worker support is low. Surface acting also decreases the subsequent engagement of organizational citizenship behaviour through decreasing the experience of positive affective states. We conclude with a discussion of how surface acting can consequently lead to negative spirals in the organization and the implications of this for practice. 相似文献

Healthcare practitioners’ fitness to practise has often been linked to their personal and demographic characteristics. It is possible that situational factors, such as the work environment and physical or psychological well-being, also have an influence on an individual’s fitness to practise. However, it is unclear how these factors might be linked to behaviours that risk compromising fitness to practise. The aim of this study was to examine the association between job characteristics, well-being and behaviour reflecting risky practice amongst a sample of registered pharmacists in a region of the United Kingdom. Data were obtained from a cross-sectional self-report survey of 517 pharmacists. These data were subjected to principal component analysis and path analysis, with job characteristics (demand, autonomy and feedback) and well-being (distress and perceived competence) as the predictors and behaviour as the outcome variable. Two aspects of behaviour were found: Overloading (taking on more work than one can comfortably manage) and risk taking (working at or beyond boundaries of safe practice). Separate path models including either job characteristics or well-being as independent variables provided a good fit to the data-set. Of the job characteristics, demand had the strongest association with behaviour, while the association between well-being and risky behaviour differed according to the aspect of behaviour being assessed. The findings suggest that, in general terms, situational factors should be considered alongside personal factors when assessing, judging or remediating fitness to practise. They also suggest the presence of different facets to the relationship between job characteristics, well-being and risky behaviour amongst pharmacists. 相似文献

The current research hypothesized that individual social capital facilitates the implementation of one's intention to start a business. The research samples were drawn from a sample of 2061 adult respondents: a sub‐sample of 269 adults who stated their intention to start their own business during the next two years (‘intenders’) and a matching sub‐sample of 270 who said they did not intend to do so (‘non‐intenders’). The study shows that the ‘intenders’ possessed greater individual social capital. These resources had a positive indirect impact (through increased perceived behavioural control and attitude) on their intention to start their own business. 相似文献

IntroductionSocial and self-identities have been conceptualised to prevent travel behaviour change, as threats to one’s identity may cause resistance to change. This study focuses on the role of social, transport, place, and self-identities on commute mode choice and intention to change mode choice.MethodData were collected in June 2015 in Utrecht, the Netherlands. Invitations to participate were distributed by mail using data from the municipality, resulting in 1062 adult participants.The outcome measures were the transport mode shares based on a 14-day travel-to-and-from-work record of trips (i) involving any car use, (ii) involving any bicycling, (iii) involving any walking, and (iv) involving any public transport use. The second series of outcome measures concerned the willingness to change the amount of car use, bicycle use and walking, determined by the question ‘to what extent do you intend to change the use of …?’. Identity was measured on a seven-point disagree/agree scale for 17 items by asking to what extent the respondent ‘sees him/herself as …’. Separate multinomial regression models were estimated stepwise adjusting for socioeconomic and transport characteristics.ResultsMultiple identity items were associated with the use of all commute modes. In the maximally adjusted models, identities associated with the respective modes remained significant. For example, whether someone identified themselves with being a cyclist corresponded with higher likelihood of cycling occasionally (relative risk ratio (RRR): 1.84; 95% confidence interval (CI):1.47–2.30), or always to work (RRR: 2.86; 95% CI: 2.16–3.79). In addition, we found that a family-oriented identity was negatively associated with occasional commuting by car, and a ‘sporty’ identity was negatively associated with always cycling to work.Transport identities were also associated with stated intentions to change as were several social, place, and self-identities. Identifying with being a car driver decreased the likelihood of intending to reduce car use, but it increased the likelihood of intending to increase car use, as did identifying with being career-oriented. Individuals that identified with being a cyclist were less likely to have an intention to reduce bicycle use, whereas countryside-lovers had greater intentions of increasing cycling. Individuals that identified themselves as pedestrians had a lower intention of decreasing their walking levels, and a higher intention of increasing them, as did those who identified themselves as being family-oriented.DiscussionThe results confirm limited previous findings that identifying with users of a transport mode correspond with its use. Nevertheless, questions around causality remain. The intention to change mode choice was associated with several identities, including transport-related identities, place-related identities, social/family-related identities, and self-identities. Future research should focus on the associations between identity and actual behaviour change to further our understanding of the effect of identity on travel behaviour. 相似文献

This study investigated the extent to which employees’ perception of ethical leadership moderated their organisational commitment and organisational citizenship behaviour. A non-probability purposive sample (N = 839; females = 32%) of employees in a railway organisation in the Democratic Republic of Congo (DRC) participated in the study. They completed the following measures: the Organisational Commitment Scale (OCS), the Organisational Citizenship Behaviour Questionnaire (OCBQ) and the Ethical Leadership Scale (ELS). Stepwise hierarchical regression analysis was utilised to determine the influence of employees’ perceptions of the relationships between their self-reported organisational commitment and organisational citizenship behaviour. The results indicated employee perceptions of the integrity, fairness and honesty aspects of ethical leadership to explain their affective, continuance and normative aspects of organisational commitment and organisational citizenship behaviour. The results also showed that employee perceptions of high ethical leadership influenced their willingness to engage in positive organisational commitment such as psychological attachment, work continuance, normative commitment and also their organisational citizen behaviours such as altruism, conscientiousness, courtesy and civic virtue. By implication, leaders with high ethical conduct have the potential to positively stimulate the commitment of employees towards supporting the organisational values and mission. 相似文献

This exploratory qualitative study aimed to provide insight into the factors contributing to the high prevalence rate of teenage pregnancy in South African communities. Focus group were conducted with 193 community members (females = 44.6%; adults = 50.8%, teenagers/youth = 44.0%) and followed by thematic content analysis to interpret the data. Several overarching themes regarding the increasingly common occurrence of teenage pregnancy emerged from the data. These included: (1) the increased acceptability of teenage pregnancy to families and communities for economic and material gain; (2) the influence of social pressure; and (3) the lack of sexual knowledge and provision of sex education. Community members perceived teenage pregnancy as an increasingly common occurrence in their communities. Community members perceived teenage pregnancy to be driven by multiple factors and to require holistic interventions at the individual, family and community level. 相似文献
