Planning framework of analytical approaches applied to Zairean transportation

The purpose of the article is to provide an analytical planning framework which includes decision makers, organizations imposing operational and institutional constraints, direct customers and indirect beneficiaries. All these actors have differ-ent, only partially overlapping, interests; this increases the complexity of capital budgeting and imposes limitations on decision-making framework has important implica-tions for project selection, charging and depreciation policies. Although the illus-trations are limited to transport planning, the framework can be easily applied to any sector or country. For example, the English engineering students applied the framework to 18 industries in the U.K.: Auto-diesels, Bass, British Airways, British Gas, British Oxygen, British Petroleum, British Rail, British Steel, British Telecom, East Midland Electricity, Guinness, Imperial Chemical Industries (ICI), Inter-national Computers Limited (ICL), Marks & Spencer, Mercury Communications, National Westminster Bank, Rover and Thames Television (see A. Kelvin, 1993, Increasing student participation in the learning process. Higher Education, 26(4), December, 449-470).     

Digging Deep: Managing Social and Policy Dimensions of Geoduck Aquaculture Conflict in Puget Sound,Washington

Shellfish aquaculture can result in conflicts among stakeholders who perceive impacts and tradeoffs regarding sense of place, aesthetic, recreational, economic, and ecological values. Pacific geoduck clams (Panopea generosa Gould 1850) are grown in intertidal plots using gear- and labor-intensive techniques that result in a high value export product. A confluence of issues has resulted in on-going social and legal tensions surrounding geoduck aquaculture in southern Puget Sound, Washington (WA), USA. Using interviews and document analysis, we explored stakeholder perspectives and policy issues related to geoduck aquaculture in southern Puget Sound. Twenty-three stakeholders were interviewed, including state agency employees, representatives of the aquaculture industry, nongovernmental organizations, landowners, a tribal member, and an academic. Nine state hearings board decisions on challenges to aquaculture permits were also analyzed. Stakeholders articulated a variety of perspectives regarding aesthetic, recreational, land-use, ecological, political, regulatory, and economic aspects of geoduck aquaculture activities. Hearings board cases addressed similar issues (aesthetic, ecological, and recreational), as well as challenges to restrictions on aquaculture. Potential strategies for managing this conflict include emphasizing best management practices, identifying and incorporating best available science, joint fact-finding approaches, and initiating and improving communication among all stakeholders.

Factoring a real value of cargo in port investment and funding decisions

Ports are marine gateways to economic activities. Ports’ ability to perform services depends on their facilities, harbor conditions, and other factors. Generally, ports have control over their facilities but must compete for funding to improve them. As for waterways, in the U.S., a Harbor Maintenance Trust Fund was established to fund dredging, which levies a 0.125% cargo value tax on most shippers using U.S. coastal and Great Lakes harbors. Yet, commonly, a gross tonnage metric is used to allocate the fund’s resources, resulting in under-maintenance of some harbors. This, reportedly, deters additional port funding and hinders valuable commerce. Supplemental economic metrics, such as value of commerce or cargo, can improve port financing decisions, but such data is not readily available. Container ports collect cargo value data in nominal terms, but bulk ports do not. When making economic decisions, however, real values must be used. Further, when allocating resources, decision-makers must be able to assess ports over time and relative to each other. Conforming to these criteria, this paper develops three port financing indicators based on a real value of cargo and illustrates their calculations using the U.S. Port of Duluth-Superior as a case study.     

Duration analysis for recurrent ship accidents

About 63% of the world’s shipping accidents are recurrent—they occur to ships that have already experienced at least one prior accident. Therefore, reducing recurrent accidents can contribute significantly to maritime safety. We study the factors affecting both first and recurrent accidents, by focusing on the duration between two accidents. Cox proportional hazard models are applied to ship accident data from 1996 to 2015, and the results identify which ships have a high risk of recurrent accidents, based on ship attributes, ship supply and market conditions, shipbuilding country, previous accident type, and ship type. The recurrent rate is high when the ship involved in the accident is old, small, flies a flag of convenience, and has no detention record. In addition, the accident risk increases when the shipping market faces a high bunker price, overcapacity in supply, a high time charter rate, or low newbuilding price. On the other hand, ships built in China and Japan have lower recurrent accident rates than those built elsewhere, although ships built in China have earlier first accidents than do others. General cargo ships have the highest recurrent accident rate, followed by dry bulkers, container ships, and tankers, in that order.     

Outsourcing rural school transportation: A Brazilian handbook for practice at the municipal level

In Brazil, Rural School Transportation (RST) falls under the responsibility of state and municipal governments. However, there are no clear rules to guide the provision of this essential service. RST in Brazil is characterised by inefficient contracting practices, poor service control by school administration, and lack of legal instruments to penalise poor services, thus allowing operators to run services according to their own commercial criteria. In addition, payment is low, leading to the employment of old vehicles, lack of safety equipment, and non-convenient routes, among other aspects. As a result, school children provided with this service are subject to long travel time over large distances, and irregular and late services, coupled with poorly maintained roads. When children finally arrive at school they are tired, which often negatively affects their school performance and attendance, contributing to early school drop-out. In order to contribute to the improvement of school transportation quality, state and municipal authorities must develop the required organisational, planning, and regulatory skills. Accordingly, this article addresses the elements and the structure of a handbook that is being elaborated for local governments.

Formulation of consistent nonlinear restoring stiffness for dynamic analysis of tension leg platform and its influence on response

Shortcomings of the traditionally used nonlinear restoring stiffness of TLPs, i.e. unrealistically high stiffness of horizontal motions, their uncoupling and secant formulation are pointed out. Therefore, new consistent restoring stiffness is derived. The platform is considered as a rigid body moored by flexible pretensioned tendons. Global horizontal low frequency motions (surge, sway and yaw) with large amplitudes as a result of dominant second order wave excitation and small stiffness, and vertical local motions (heave, roll and pitch) of higher frequency and small amplitudes excited by the first order wave forces, are distinguished. Hence, horizontal displacements represent position parameters in analysis of vertical motions. First, the linear restoring stiffness, which consists of the tendon conventional axial stiffness, the tendon geometric stiffness and the platform hydrostatic stiffness, is established. Then it is extended to large displacements resulting in new secant restoring stiffness. It depends on surge, sway and yaw displacements and is the same in any horizontal direction. Also, the tangent stiffness, which gives more accurate results, is derived. Heave is defined as vertical projection of axial tendon vibrations and platform tangential oscillations, which are analyzed in their natural moving coordinate system. Inertia force due to setdown, as a slave d.o.f. of the master horizontal motions, is taken into account in the dynamic equilibrium equations. As a result the complete tangential stiffness matrix of horizontal and vertical motions includes 7 d.o.f. The known secant restoring stiffness matrices are compared with the new one and noticed differences are discussed. All theoretical contributions are illustrated by relatively simple numerical example.
