Social networks,social influence and activity-travel behaviour: a review of models and empirical evidence

ABSTRACT

The study of social networks in activity-travel research has recently gained momentum because social activities and social influence were relatively poorly explained in activity-based models of travel demand. Over the last decade, many scholars have shown interest in identifying personal social networks that constitute an important source of explanation of activity-travel behaviour. This paper seeks to review two research streams: social networks and activity-travel behaviour, and social influence and travel decisions. We classify models, summarise empirical findings and discuss important issues that require further research.     

Effects of job demands and social interactions on fatigue in short sea cargo shipping

Although fatigue is considered an important problem in shipping, little is known about potential mitigating factors or resources for coping. Adopting a Job Demands–Resources framework, this article examines the effects of both job demands (stressors) and resources on fatigue, focusing on social interactions on board as a potential source of social support. Using an incomplete repeated-measures design, the study combined information from documents with surveys on seven cargo ships. Findings indicated that fatigue levels were highest for those working on deck and for individuals at higher hierarchical levels. Higher numbers of port calls (and to some extent lower numbers of days at sea) also increased fatigue levels. By contrast, night watches and the number of days in port had no effect on fatigue. Supportive social interactions reduced fatigue (main effect), but their effect was weaker when the number of port calls increased (interaction effect). All main effects were mediated by individuals’ perceptions of work pressure. Taken together, findings highlight the importance of considering social interactions on board to advance our understanding of stressors and strain in seafaring.

客运专线综合运营调度系统Agent结构和规则描述

为提高客运专线综合运营调度系统的智能性,采用智能体(Agent)技术,将运输调度决策过程看作是Agent之间的协商过程,建立了客运专线综合运营调度系统的多智能体(MAS)体系结构。将列车运行调度子系统、动车组调度子系统、牵引供电调度子系统和车站分别抽象为Agent,所有Agent构成了Agent社会,给出了Agent社会规则。在体系结构的基础上,给出了二路四层垂直型结构的公司行调Agent结构和反应式车站Agent结构,并阐述了其工作原理。仿真结果表明:在遵循社会规则下,Agent能在10s内调整列车运行计划,5s内选取调度预案,因此,MAS体系结构可行,能够提高运营调度系统的智能性。
