Cautious behaviors of pedestrians while crossing narrow streets: Exploration of behaviors using virtual reality experiments

This study explores the cautious behaviors of pedestrians in a typical local street environment using virtual reality (VR)-based experiments under various physical safety design scenarios for roadways. The built environment of this study focused on narrow local roads where frequent daily walking occurs within a neighborhood. VR experiments can provide an objective and accurate measurement of pedestrian behaviors, thus improving the understanding of complicated pedestrian behaviors. Based on experimental data from 200 university students, we identified pedestrians’ crossing behavior that is cautionary or risky concerning various physical safety designs of streets. This study found that there are trade-off relationships between various behaviors which should be systematically studied to produce safer street design guidelines. Furthermore, as the contexts and sequences matter in behaviors for intersection crossing, the interpretation of behaviors should carefully consider the context of built environments and sequential decisions made by pedestrians. This sequential understanding of before- and during-crossing behaviors and their connections expands our knowledge of pedestrians’ crossing behaviors.     

More Rational or More Emotional Than Others? Lay Beliefs About Decision-Making Strategies

Research demonstrates that people utilize both reasoning and feeling in decision making and that both strategies can be advantageous. However, little is known about how people perceive their decision-making relative to others. Despite research findings and popular appeals supporting the use of affective decision processes, across a series of studies, we find that individuals believe they rely more on reasoning, and less on feelings, than others. These effects are driven by the motivation to self-enhance where, in most contexts, individuals believe the use of reasoning is superior, and self-enhancing, compared to the use of feelings. Consistent with this mechanism, beliefs that one’s decisions are more rational than others’ are as follows: (a) stronger for those who exhibit greater beliefs in the superiority of reasoning (vs. feeling), (b) attenuated when the decision context precludes motivational thinking about the self or the self is affirmed, and (c) reversed when the use of feelings is perceived as more self-enhancing. We demonstrate downstream consequences (e.g., decision delegation), rule out alternative explanations, and discuss practical implications of these lay beliefs.     

Better to Decide Together: Shared Consumer Decision Making,Perceived Power,and Relationship Satisfaction

Shared consumer decisions, particularly those made with a relationship partner, can be very different from decisions that are made alone. Across multiple studies, we investigate how shared consumer decision making affects perceptions of power and relationship satisfaction. We integrate two streams of research to create a novel theory about consumer decision making and perceived power. Specifically, we suggest that shared consumer decision making combines two necessary components of power—an individual's influence over and a partner's engagement in the decision—and that these combined components drive power perceptions. In other words, individuals who relinquish some control and make a decision with their partner, ironically, perceive having greater power than if they had made the decision alone. We further find that shared decision making and greater perceived power lead to greater satisfaction with the relationship in which the decisions are made. By focusing on consumer decision making within relationships, the current research contributes to the literatures on decision making, social influences in consumer behavior, close relationships, consumer well-being, and power.     

Impact on driver behaviour of guardrails of different height in horizontal-vertical coordinated road scenarios with a limited available sight distance

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.

The role of individual and parental expectations in student-athletes’ career adaptability profiles

ObjectivesTo support holistic development, adolescent student-athletes are encouraged to integrate sport with education/academics (i.e., dual careers). Career adaptability, as a psychological resource, may help youth athletes cope with transitions and successfully manage their careers. Individuals with a plan and higher expectations for the future demonstrate higher career adaptability and are better prepared for the future. In the present study, we examined what kinds of distinct career adaptability profiles could be identified among youth athletes in Finland at the transition stage to a sports high school (i.e., specialized school for athletes). Moreover, we investigated whether youth athletes’ success expectations about school and sport, and corresponding parental expectations, predicted the probability of student-athletes demonstrating a certain career adaptability profile. Next, we examined how gender was represented in the different profiles. Design and methods: The present study is part of the Longitudinal Finnish Dual Career study. A total of 391 student-athletes (51% females) from six sports high schools in Finland, and 448 parents (42% fathers) participated in the study. The student-athletes answered questionnaires on career adaptability (Career Adapt-Abilities Scale – Dual Career Form) and success expectations at the beginning and then again at the end of the first year of sports high school. At the beginning of sports high school, parents responded to a questionnaire about their expectations of success for their children in both academics and in sport. The data were analyzed using structural equation modeling and latent profile analysis. Results: Five distinct adaptability profiles across time were identified: stable, very low adaptability, stable low adaptability, stable moderate adaptability, stable high adaptability, and increased adaptability. Student-athletes’ high success expectations in academics and sport, and mothers’ high success expectations in academics, increased the probability of student-athletes showing higher adaptability profiles. Conclusions: The student-athletes’ high level of expectations for both sport and academics are associated with career adaptability, and mothers’ high expectations of student-athletes’ academic success relate to higher career adaptability profiles among student-athletes and can thus be considered an important factor in supporting their dual careers.     

A Biased Inferential Naivety learning model for a network of agents

We propose a Biased Inferential Naivety social learning model. In this model, a group of agents tries to determine the true state of the world and make the best possible decisions. The agents have limited computational abilities. They receive noisy private signals about the true state and observe the history of their neighbors' decisions. The proposed model is rooted in the Bayesian method but avoids the complexity of fully Bayesian inference. In our model, the role of knowledge obtained from social observations is separated from the knowledge obtained from private observations. Therefore, the Bayesian inferences on social observations are approximated using inferential naivety assumption, while purely Bayesian inferences are made on private observations. The reduction of herd behavior is another innovation of the proposed model. This advantage is achieved by reducing the effect of social observations on agents' beliefs over time. Therefore, all the agents learn the truth, and the correct consensus is achieved effectively. In this model, using two cognitive biases, there is heterogeneity in agents' behaviors. Therefore, the growth of beliefs and the learning speed can be improved in different situations. Several Monte Carlo simulations confirm the features of the proposed model. The conditions under which the proposed model leads to asymptotic learning are proved.     

Soutien social perçu du supérieur,plafonnement de carrière et engagement affectif dans le secteur public camerounais

This research analyzes relation between the various types of career plateauing (objective, structural, content) and work emotional commitment. It also examines the influence of perceived social support from hierarchy on the different types of career plateauing, most especially its moderating role on the relation between the different types of career plateauing and emotional commitment. The results, which were obtained through data collected from 615 workers highlight that perceived social support from hierarchy limits and almost moderates negative relations between the different types of content plateauing (objective, content) and emotional commitment. Its direct effect on content plateauing is negative whereas the relation is positive with structural plateauing.
