Accident statistics show that transitions from rural to urban areas are accident prone locations. Inappropriate speed and mental underload have been identified as important causal factors nearby such transitions. A variety of traffic calming measures (TCM) near rural–urban transitions has been tested in field experiments and driving simulator studies. Simulator experiments repeatedly exposing participants to the same treatment are scarce, hence it is unclear to what extent the effects of a TCM endure over time.This is precisely the objective of the current study: to examine what happens with the behavior of drivers when they are exposed multiple times to the same treatment (in this case a gate construction located at a rural–urban transition). Over a period of five successive days, seventeen participants completed a 17 km test-drive on a driving simulator with two thoroughfare configurations (gates present or absent) in a within-subject design. Results indicate that gates induced a local speed reduction that sustained over this five-day period. Even though participants were inclined to accelerate again once passed by this gate configuration, they always kept driving at an appropriate speed. We did not find any negative side effects on SD of acceleration/deceleration or SDLP.Overall we conclude that gate constructions have the potential to improve traffic safety in the direct vicinity of rural–urban transitions, even if drivers are repeatedly exposed. Notwithstanding, we advise policy makers to appropriately use this measure. Best is to always carefully consider the broader situational context (such as whether the road serves a traffic- rather than a residential function) of each particular location where the implementation of a gate construction is one of the options. 相似文献

以中国样本为例,运用元分析方法对个体和团队层面情绪智力与工作相关变量的关系进行了探讨。来源于46项研究的59个独立样本满足了元分析标准(N=11578)。元分析结果发现,个体情绪智力与领导行为有高度正相关,与任务绩效、背景绩效、自我效能感有中高度正相关,与工作满意、组织承诺、创新行为有中低度正相关,与工作倦怠有中高度负相关,与工作压力有中低度负相关,与员工离职和凝聚力的相关不显著。团队情绪智力与团队绩效高度正相关。结果表明,情绪智力是工作场所有价值的变量,它对有效的工作变量有不同程度的预测性。 相似文献

阅读研究中的主要眼动指标评述 总被引:2,自引:0,他引:2
眼跳和注视是阅读过程中的两种基本眼动现象.目前在对阅读的眼动研究中分析指标主要包括两类,一类是与眼睛何时移动有关的时间维度的眼动指标,具体包括以字或词为兴趣区的眼动指标,如单一注视时间、首次注视时间、第二次注视时间、凝视时间、离开目标后的首次注视时间、回视时间和总注视时间等,以及以短语或句子为兴趣区的眼动指标,如第一遍阅读时间、向前阅读时间、第二遍阅读时间、回视路径阅读时间、重读时间等.另一类是与眼睛移动位置有关的空间维度的眼动指标,具体包括眼跳距离、注视位置、注视次数、跳读率、再注视比率和回视次数等.在使用眼动指标时,需要注意眼动指标的分类、原始数据的删除标准以及眼动指标的选择等问题. 相似文献

PurposeYoung soccer players need excellent tactical skills to reach the top. Tactical behavior emerges through interactions between opposing teams. However, few studies have focused on on-field tactical behavior of teams with talented soccer players. Therefore, this study aimed to determine teams’ tactical behavior during small-sided games in two age categories, Under-17 and Under-19.MethodsPositional data of thirty-nine elite-standard soccer players were collected during twenty-four small-sided games to calculate longitudinal and lateral inter-team distances, stretch indices and length per width ratios. Corresponding interaction patterns and game-to-game variability were also determined.ResultsUnder-19 showed a significantly larger lateral stretch index and a significantly lower length per width ratio compared with Under-17. Furthermore, teams of both age groups showed similar large proportions of in-phase behavior. Variability of tactical performance measures within and between games was similar for Under-17 and Under-19.ConclusionsVariability within games seems to be functional for attacking teams for creating goal-scoring opportunities. In conclusion, the main difference was that Under-19 adopted a wider pitch dispersion than Under-17, represented by a larger lateral stretch index and smaller length per width ratio. Coach instructions and training exercises should be directed at exploiting pitch width to increase the pursuit of goal-scoring. 相似文献

The present experiment set out to investigate the affective consequences of dispositional optimism and attribution in performance settings. Optimistic and pessimistic participants (N = 42 each) experienced failure at solving two cognitive tasks in an alleged team setting. The failure could either be attributed to themselves (internal condition) or a teammate (external condition). We found disordinal interactions of optimism and attribution on the feelings of success and feelings of failure. While the affective state of optimists deteriorated significantly if they attributed the failure internally compared to externally, pessimists were emotionally unaffected by the locus of attribution. Moreover, optimists experienced affective benefits compared to pessimists when they attributed the outcome externally. The reverse was true if they had attributed internally. Affective consequences of optimism and pessimism after failure therefore seem to differ depending on attributions. Furthermore, pessimists seemed to be unresponsive to the affective effects of attribution in our study. This insensitiveness implies differences in the cognitive processing of outcomes, a trait × cognition interaction that should be investigated further. 相似文献

This study has been designed to investigate, from a multilevel perspective, the relations among positivity and job performance. Analyses were conducted on a sample of 232 participants from three Italian organizations with the Group Actor-Partner Interdependence Model (Kenny & Garcia, 2012). Results corroborate previous findings attesting to the beneficial effects of positivity on organizational behaviours and in particular attest to the crucial role of others’ positivity in neutralizing an individual’s low positivity. People low in positivity performed better when other group members’ positivity was high. 相似文献

We evaluated the validity of the Overclaiming Questionnaire (OCQ) as a measure of job applicants’ faking of personality tests. We assessed whether the OCQ (a) converged with an established measure of applicant faking, Residualized Individual Change Scores (RICSs); (b) predicted admission of faking and faking tendencies (Faking Frequency, Minimizing Weaknesses, Exaggerating Strengths, and Complete Misrepresentation); and, (c) predicted the aforementioned measures as strongly as RICSs did. First, 261 participants were instructed to respond honesty to an extraversion measure. Next, in a mock job application, they filled out the extraversion measure again, as well as the OCQ. The OCQ only weakly predicted RICSs (r = .17), Faking Admission (r = .18), and Faking Frequency (r = .15), and it failed to correlate significantly with Minimizing Weaknesses, Exaggerating Strengths, and Complete Misrepresentation. Moreover, the OCQ performed significantly worse than RICS in predicting Faking Admission, Faking Frequency, Minimizing Weaknesses, Exaggerating Strengths, and Complete Misrepresentation. We urge caution in using the current version of the OCQ to measure faking, but speculate that the innovative approach taken in the OCQ might be more effectively exploited if the OCQ content were tailored to the specific job that applicants are being tested for. 相似文献

In his seminal 1992 paper, Dunbar examined three hypotheses advanced to explain primate intelligence, arguing that whereas his social group size hypothesis was supported, neither of two ecological hypotheses, the extractive foraging and frugivory hypotheses, were supported. Following this, and Dunbar's subsequently elaborated argument, many investigators concluded that primate intelligence arose as social rather than ecological adaptations. This paper questions Dunbar's characterization of extractive foraging and social intelligence as alternative hypotheses, raises sampling issues about Dunbar's brain data, species choice, and measurement of extractive foraging. It summarizes the extractive foraging hypothesis, and counters its critics. It reexamines the hypothesis in light of recent behavioral and brain data, new methodology for quantifying extractive foraging, and a new phylogeny of primate intelligence. It concludes that the extractive foraging hypothesis is now supported by several converging lines of evidence. 相似文献
