Abstract: Existing studies show that effort made so far in curtailing marine pollution in ports of developing economies is marred by lack of administrative controls and inadequate provision of waste reception facilities at the ports. In this paper, sources of marine pollution and effects of particularly ship-based pollutants on marine environment were examined. The institutional arrangement for addressing marine pollution from ships visiting Nigeria ports is evaluated within the context of Marine Pollution (MARPOL) convention provisions and the obligations of coastal, flag states and port state control in ensuring compliance. It was found that in Nigeria ports, ship-generated waste control services and provision of waste reception facilities are outsourced to a private company with no requirement for activity audit. Apart from the Nigeria Port Authority (NPA), other government agencies are also involved in pollution monitoring and control. Given this scenario, it is envisaged that functions could be duplicated and monitoring/control efforts potentially weakened by conflicts of interests. An integrated administrative framework model is therefore proposed to address these managerial issues. Policy implications of the model developed are discussed.

Abstract: Traffic engineering uses engineering methods and techniques to achieve the safe and time efficient movement of people and goods on roadways. The safe and time efficient movement of people and goods is dependent on the transit system performance, which is directly connected to the traffic characteristics. The main parameters of performance of transport shuttles are traffic volume, speed, density and revenue; and all these are evaluated in this study. In the absence of effective planning and traffic management, current road infrastructure will not be able to cater for the future needs of the University. Students, staff and vehicle volumes have increased significantly in the last decade in the Institution, yet the performance of the transport shuttle have been dismal and unable to achieve its objectives. Findings of the study show that the morning peak period (8.00am to 9.00am) has 234 vehicles/hr, evening peak period (2.00pm to 3.00pm) has 284 vehicles/hr, while the off-peak period (11.00am to 12.00pm) has 156 vehicles/hr. The journey time from the Post Office bus stop to the University campus, measured as 34.01 minutes, was too long for the distance of 15.0km road which according to the Nigeria Highway Code should not be more than 18 minutes. The average stopping time was 6.55 minutes, average interval between arrivals of motorists was 16.40 seconds, the average queue length was 14.23 people, and the average waiting time at the bus-stop 4.17 minutes. These values were obtained using the queuing theory and shows much commuters time is lost on transit queues. The financial condition of the transit unit shows that amount generated is less than the amount expended by the transit operators. This means, in effect, that the shuttle bus operators are operating in deficit.

Abstract: Just-in-time technique is used to enhance firms’ performance, service level and reduce/eliminate waste from the end-to-end system. Undeniably, just-in-time is playing significant role in the today’s world to achieve firms’ objective in terms of high service level with minimum cost. This research’ objective is to fill the gap by forming, organizing an complete picture of a Just-in-Time execution process from the opinions of both academicians and practitioners by comparing results based on different research methods. This research is based on secondary method used to collecting and summarize to the very relevant articles, which has been published. Uncountable studies including; said Just-in-Time education is a critical factor in JIT execution. The results show several factors involved in the just-in-time implementation such as, quality circle, reduction in set-up time, quality certificate of suppliers, cross-training, just-in-time education, relationship with supplier, schedule stability, top management commitment towards JIT project, in-house lot sizes etc. The researchers also discussed research implications in detailed.

Abstract: In the todays’ world, supply chain and distribution play a significant role in the firm businesses. This research aim is to describe supply chain and distribution problems. The researchers have established many numbers of ontological models to describe their own perspective. The inductive approach is used for the development of theory process that begin with observation of particular instances and finds to build, establish generalizations about the phenomenon below investigation. As well as, deductive approach of research is used for process of theory testing, which commences with an established theory or generalization and finds to look if the theory is able to apply into particular instances.

Abstract: Supply chain management have a significant role in the firms’ business. In the modern time, collaboration with supply chain partner is very important to fulfil the requirement of customers. In this research paper, we will discuss the dichotomy among the trust building and the use of power in the collaboration of supply chain. In specifically, we find a kind of supply chain interaction we have called “dictatorial collaboration.” This oxymoronic term refers to relationships of business in which one of the entities wields sufficient power “derived from its market position, size, system capabilities and strategic importance, etc.) to force over other companies in its supply chain to provide value added services or perform operational tasks that advantage the leading, dominant company without sharing the gain with the other companies. The results show that that problem of dictatorial supply chain behaviour has, to date, not been much discussed before in the ethics literature, it is our hope that our current performance of this issue gives the motivation for further research, investigation in future and grant, scholarship about the ethics of collaborative relationships in the supply chain management.
