Efficiency challenges of the hinterland connectivity, along with growing green concerns necessitate the integration of economic goals and environmental considerations, for port-hinterland logistics problems. This study focused on innovative modeling, for a three-mode port-hinterland intermodal freight distribution system, from the perspective of shippers. A hybrid distribution network topology, combining point to point, hub-and-spoke, and connected hubs was designed as route alternatives for loads from origin to destination. A bi-objective decision framework involving analytical scenarios of emissions limitation, emissions taxation, and an emissions trading scheme, was developed for policy analysis, and then applied to a real-life hinterland logistics network in the Yangtze River Economic Belt in China. The results showed that the implementation of the three emissions policies, all resulted in great changes in flows between intermodal routes and achieved emissions reduction goals. Nevertheless, the conflict between logistics costs and carbon emissions, differs from policy to policy. Some inflection points were identified to offer decision supports on policy insights, for the port-hinterland distribution network. Lastly, a sensitivity analysis on cost and emissions parameters was given. It revealed that the flow changes and trade-off relationship between economic and environmental objectives, were both sensitive to the road transportation mode.

This paper develops a new model, which allows for the co-existence of hub-and-spoke and point-to-point networks in the airline industry. Passengers are segmented between the non-stop and one-stop services. In the baseline model, the monopoly airline’s ability to segment the market and effectively set up the mixed network depends on the cost savings due to the through-hub service relative to exogenous quality difference between the one-stop and non-stop flights. Socially inefficient entry with the new non-stop service where an incumbent is operating the hub-and-spoke network is possible.

As the organization of container shipping in the Yangtze River does not comply with the principle that "large ship with long line, small with short line", Hub-and-Spoke network is applied to this area to centralize traffic flow and achieve economies of scale, with the axis between Wuhan Yangluo Port and Shanghai Yangshan Port. Compared with traditional mode of transport, the new mode reduce the transport costs and fuel consumption by 15.3% and 20.1% respectively. Further, the carbon emissions are cut down by 318 thousand tons. It presents excellent economic and social benefits.

Job satisfaction is an important factor for employees working in formal and informal sector. The job is small or big, permanent or temporary, risky or non-risky, job satisfaction is important. It is the mental feeling which drives the employees to excel. Job satisfaction is a combination of psychological, physiological and environmental circumstances. A satisfied employee is a contented and happy human being. The labour turnover depends upon job satisfaction. Even highly paid employees quit the job when they are not satisfied with the job. Road transportation in Tamilnadu is growing day by day. Job stress in the road transportation is very high due to increase in number of vehicle playing on the road and heavy traffic. The drivers and conductors working in public transport corporation are suffering from high job stress. If drivers and conductors are not satisfied with their job which leads to mental stresses and affects the productivity and also creates accidents. In this present study the researchers made an attempt to study the level of job satisfaction among the drivers and conductors who are working in the Tamilnadu State Transport Corporation (TNSTC). The study reveals the expectations of drivers and conductors working in TNSTC with regards to the attributes like salary, promotion and fringe benefits etc., are satisfactory and not detrimental.
