Drivers consider traffic barriers (e.g., guardrails) a protection system, a hard obstacle and a sight obstruction. Hence, the possibility of using containment level barriers which are higher and superior than the minimum required by current standards should be carefully evaluated. Moreover, research investigations into their impact on driver behaviour should be designed so as to distinguish between the effects associated with each of the three roles cited above.This driving simulation study investigates how drivers adapt their longitudinal and transversal behaviour when negotiating curves with guardrails of different heights on horizontal-vertical coordinated two–lane rural road settings, with consideration given solely to the sight obstruction effect of the guardrails. Fifty-four participants drove four out of the eighteen possible scenarios obtained when the same horizontal alignment is combined with three vertical profiles with three inner roadside treatments (no guardrails, 0.75 m two–wave and 0.95 m three-wave guardrails) and the two driving directions.Research outcomes confirm that guardrail height has a significant impact on lateral and longitudinal behaviour. With the minimum standard, i.e., the minimum height, drivers stay closer to the roadside, while higher guardrails result in drivers increasing their lateral distance. Speeds are influenced by the interaction between the guardrail and other geometric and human factors. Male and female drivers adapt differently to the limitation in the available sight distance caused by the guardrail: males increase their speed, adopting a more aggressive behaviour than females. Important safety implications due to the higher speeds and wider trajectories have to be considered at the design stage. 相似文献

While playing an important role in psychic development and sustenance as well as in triggering or causing psychopathology, neighbors have attracted little attention from psychoanalysts. Freud's wry protest against the Biblical injunction to love thy neighbor as thyself and Volkan's psychopolitical studies of ethnic neighbors are exceptions in this regard. Taking them as a starting point but going much farther, this paper elucidates the complex relationships that exists between actual neighbors. It also sheds light on the “neighborly” aspects of the analyst–patient bond. Finally, it underscores the existence of unassimilated self-representations within each individual that can be viewed as neighbors to his or her core self and deserve benevolent acknowledgment and acceptance. 相似文献

The misclassification error distance and the adjusted Rand index are two of the most common criteria used to evaluate the performance of clustering algorithms. This paper provides an in-depth comparison of the two criteria, with the aim of better understand exactly what they measure, their properties and their differences. Starting from their population origins, the investigation includes many data analysis examples and the study of particular cases in great detail. An exhaustive simulation study provides insight into the criteria distributions and reveals some previous misconceptions. 相似文献

Estimating the size of bodies is crucial for interactions with physical and social environments. Body-size perception is malleable and can be altered using visual adaptation paradigms. However, it is unclear whether such visual adaptation effects also transfer to other modalities and influence, for example, the perception of tactile distances. In this study, we employed a visual adaptation paradigm. Participants were exposed to images of expanded or contracted versions of self- or other-identity bodies. Before and after this adaptation, they were asked to manipulate the width of body stimuli to appear as ‘normal’ as possible. We replicated an effect of visual adaptation such that the body-size selected as most ‘normal’ was larger after exposure to expanded and thinner after exposure to contracted adaptation stimuli. In contrast, we did not find evidence that this adaptation effect transfers to distance estimates for paired tactile stimuli delivered to the abdomen. A Bayesian analysis showed that our data provide moderate evidence that there is no effect of visual body-size adaptation on the estimation of spatial parameters in a tactile task. This suggests that visual body-size adaptation effects do not transfer to somatosensory body-size representations. 相似文献

This paper explores the experience of working as a Jungian analyst through the various phases of the global COVID-19 pandemic, examining the importance of the physical containing space alongside the analyst’s internal mind and how technology can both help and hinder understanding. A number of clinical vignettes illustrate the challenge of communicating over a distance, paying particular attention to the way countertransference phenomena can become re-attuned. Reference is made to mythology and symbols of hope, and consideration given to the meaning and purpose of the pandemic. 相似文献

AbstractThe continuous pointing task uses target-directed pointing responses to determine how perceived distance traveled is estimated during forward linear walking movements. To more precisely examine the regulation of this online process, the current study measured upper extremity joint angles and step-cycle kinematics in full vision and no-vision continuous pointing movements. Results show perceptual under-estimation of traveled distance in no-vision trials compared to full vision trials. Additionally, parsing of the shoulder plane of elevation trajectories revealed discontinuities that reflected this perceptual under-estimation and that were most frequently coupled with the early portion of the right foot swing phase of the step-cycle. This suggests that spatial updating may be composed of discrete iterations that are associated with gait parameters. 相似文献

Choosing a larger–later reward over a smaller–sooner reward may be thought of as altruism toward one's future self. A question that arises in this connection is: What is the relation between delay and social discounting? To begin to answer this question, social and delay discount functions need to be comparable. Delay is ordinarily measured on a ratio scale (time), which allows for meaningful division and addition. Social distance is ordinarily measured on an ordinal scale (rank order of social closeness). To convert social distance to a ratio scale we use a psychophysical distance function obtained via magnitude estimation (Stevens, 1956). The distance functions obtained are well described by a power function (median exponent = 1.9); we show how they may be used to rescale ordinal to ratio social discount functions. 相似文献

This study is the first to explore the effect of political socialization in the workplace on populist attitudes. We investigate the effect of workplace voice suppression on employees' populist attitudes and voting. We expect employees who were suppressed by supervisors to hold more populist attitudes and to be more likely to vote for a populist party than employees who were not. We argue that some employees experience voice suppression by supervisors as stressful, so splitting is likely to be employed as a defense mechanism. Splitting is achieved through cognitive distinction and antagonism between “the good workers” and “the crooked bosses.” Such a split mental framework can generalize into a worldview that contrasts “the pure people” and “the corrupt elite,” a core characteristic of populism. We predict that the extent to which suppression triggers splitting and consequentially incites populist attitudes and voting depends on employees' acceptance of power distance. We test our hypotheses using SEM on survey data from 2990 members of the Dutch labor force. Our results show that experiences of voice suppression are positively related to populist attitudes and populist voting. As expected, this effect is stronger for employees who are less accepting of power distance. 相似文献

The distance from which an eyewitness views a perpetrator is a critical factor for eyewitness identification, but has received little research attention. We presented three mock-crime videos to participants, varying distance to three perpetrators (3, 10, or 20 m). Across two experiments, increased distance reduced empirical discriminability in the form of a mirror effect, such that correct identifications decreased while false identifications increased. Moreover, high confidence identifications were associated with high accuracy at 3 m (Experiment 1 and 2) and 10 m (Experiment 2), but not at 20 m. We conclude that eyewitnesses may be less likely to identify a perpetrator viewed at a distance, and also more likely to falsely identify an innocent suspect. Furthermore, there may be certain boundary conditions associated with distance and the impact it has on the confidence–accuracy relationship. More research is needed to elucidate the effect of estimator variable manipulations on the confidence–accuracy relationship. 相似文献

Prospection is associated, in varying degrees, with a sense that imagined events will (or will not) happen in the future—referred to as belief in future occurrence. The present research investigated to what extent this belief is justified and predicts the actual occurrence of events in the future. In two studies, participants rated their belief in the future occurrence of events imagined to happen in the coming month (Study 1) or week (Study 2), and the actual occurrence of events was then assessed. Results showed that the odds of event occurrence were about 2 times higher with an increase of 1 unit on the belief scale. Belief was particularly pronounced for temporally close events and was largely determined by the congruence of events with autobiographical knowledge. These results suggest that belief in future occurrence has some truth value and may inform decisions and actions. 相似文献
