TL;DR: It is found that an oil price increase of the magnitude experienced between 2002 and 2008 induces the income of cities near that port to increase by 7 percent relative to otherwise identical cities 500 kilometers farther away, which implies an elasticity of city economic activity with respect to transport costs.
Abstract: Transport costs are widely considered an important barrier to local economic activity but their impact in developing countries is not well-studied. This paper investigates the role of inter-city transport costs in determining the income of Sub-Saharan African cities, using two new data sources. Specifically, it asks how important access to a large port city is for the income of hinterland cities in 15 countries. Satellite data on lights at night proxy for city economic activity, and shortest routes between cities are calculated using new road network data. Cost per unit of distance is identified by world oil prices. The results show that an oil price increase of the magnitude experienced between 2002 and 2008 induces the income of cities near a major port to increase by 6 percent relative to otherwise identical cities 500 kilometers farther away. Cities connected to the port by paved roads are chiefly affected by transport costs to the port, while cities connected to the port by unpaved roads are more affected by connections to secondary centers. These are important findings for economic development in Sub-Saharan Africa since the majority of its population growth over the next few decades is expected to be in urban areas.
TL;DR: It is found that regional gross output could decline by as much as $13 billion at the port region level, but that resilience can reduce these impacts by nearly 70%.
Abstract: This paper develops a methodology for the estimation of the total economic consequences of a seaport disruption, factoring in the major types of resilience. The foundation of the methodology is a combination of demand-driven and supply-driven input–output analyses. Resilience is included through a series of ad hoc adjustments based on various formal models and expert judgment. Moreover, we have designed the methodology in a manner that overcomes the major shortcomings of the supply-driven approach. We apply the methodology to a 90-day disruption at the twin seaports of Beaumont and Port Arthur, Texas, which is a major port area that includes a petrochemical manufacturing complex. We find that regional gross output could decline by as much as $13 billion at the port region level, but that resilience can reduce these impacts by nearly 70%.
TL;DR: In this paper, the authors examined the effect of inter-port competition between two ports by applying a game theoretical approach and derived a non-cooperative game theoretic model where each port selects port charges strategically in the timing of port capacity investment.
Abstract: This paper examines the effect of inter-port competition between two ports by applying a game theoretical approach. We construct a non-cooperative game theoretic model where each port selects port charges strategically in the timing of port capacity investment. We derive the Nash equilibrium and obtain some propositions from the equilibrium. We then apply the propositions to the case of inter-port competition between the ports of Busan and Kobe.

Abstract: Once an audio prompt has been stored on the portable media device, the audio prompt menu is played. Subsequently, an input from a user of the portable media device is then received in response to the audio prompt menu. A command is subsequently transmitted to a remote computer. The command requests the remote computer to perform an action based on the user's input The portable media device includes a portable media device housing containing a processor, a power source, a user interface device, communications circuitry, at least one input/output (i/o) port, and a memory. The memory includes an operating system, a media database, communication procedures for communicating with a remote computer, and instructions for performing the above described method.
TL;DR: In this paper, the authors use virtual machines that, in a controlled and monitored environment, permit content, when loaded and executed, to open ports when those ports are not the authorized ones used for communications by known programs installed on the computer, an instruction backdoor is discovered.
Abstract: Techniques for detecting malicious attacks may monitor activities during execution of content (e.g., network downloads and email) to identify an instruction backdoor on a computer. An instruction backdoor is malware that opens a port for listening for instructions from a remote server. Such instructions may trigger activation of malicious activity. These techniques employ virtual machines that, in a controlled and monitored environment, permit content, when loaded and executed, to open ports. When those ports are not the authorized ones used for communications by known programs installed on the computer, an instruction backdoor is discovered.
TL;DR: In this article, a diverse group of stakeholders with expertise in climate science, engineering, economics, policy, and port management have highlighted the climate change challenge for ports and suggested a way forward through the adoption of some initial measures.
Abstract: With 80 % of world trade carried by sea, seaports provide crucial linkages in global supply-chains and are essential for the ability of all countries to access global markets. Seaports are likely to be affected directly and indirectly by climatic changes, with broader implications for international trade and development. Due to their coastal location, seaports are particularly vulnerable to extreme weather events associated with increasing sea levels and tropical storm activity, as illustrated by hurricane “Sandy”. In view of their strategic role as part of the globalized trading system, adapting ports in different parts of the world to the impacts of climate change is of considerable importance. Reflecting the views of a diverse group of stakeholders with expertise in climate science, engineering, economics, policy, and port management, this essay highlights the climate change challenge for ports and suggests a way forward through the adoption of some initial measures. These include both “soft” and “hard” adaptations that may be spearheaded by individual port entities, but will require collaboration and support from a broad range of public and private sector stakeholders and from society at large. In particular, the essay highlights a need to shift to more holistic planning, investment and operation.

TL;DR: In this paper, path dependence in seaport governance has been studied and a process of institutional stretching takes place when port authorities see a need to develop new capabilities and activities, gradually leading to a formalised governance reform but without breaking out of the existing path of development.
TL;DR: In this article, the authors considered the problem of allocating vessels along the quay in a bulk port for hybrid berth layout and dynamic vessel arrivals, and presented a mixed integer linear programming approach to model the problem, and an alternate exact solution approach based on generalized set partitioning.
Abstract: While significant contributions have been made in the use of operations research methods and techniques to optimize container terminals, relatively less attention has been directed to bulk ports. In this paper, we consider the problem of allocating vessels along the quay in a bulk port for hybrid berth layout and dynamic vessel arrivals. A key difference that distinguishes the berth allocation problem in bulk ports from that in container terminals is the presence of fixed specialized equipment facilities such as conveyors and pipelines at bulk ports. This has to be taken into consideration while modeling the handling times of vessels berthing at the port. The objective of the allocation is to minimize the total service time of all vessels berthing at the port in a given planning horizon. We present a mixed integer linear programming approach to model the problem, and an alternate exact solution approach based on generalized set partitioning. A heuristic approach based on the principle of squeaky wheel optimization is also presented. We compare the formulations from a computational perspective through extensive numerical experiments based on instances inspired from real data obtained from SAQR port, Ras Al Khaimah, UAE, the biggest bulk port in the middle east. The results indicate that the set partitioning approach and the heuristic outperform the MILP model, and can be used to obtain near-optimal solutions for even larger problem size.
TL;DR: In this paper, the authors examined the relationship between ports (port demand, port supply and value added activity in port) and regional economy from a logistics perspective that provided intellectual support for policy makers in their strategic port related decisions.
TL;DR: In this article, a longitudinal approach was used to analyse growth patterns that are exhibited by the selected ports in 1990-2010 and derive scenarios for throughput growth and additional quay length required up to 2025.

TL;DR: In this paper, the authors consider the problem of transmitting a first media stream associated with a media session using a first IP:port number as a source IP address and source port, and using a second IP: port number as the destination IP address.
Abstract: An example method may involve transmitting a first media stream associated with a media session using a first IP:port number as a source IP address and source port, and using a second IP:port number as a destination IP address and port; receiving a second media stream from the second IP:port number; acquiring a third IP:port number; determining a network quality associated with the first IP:port number and a network quality associated with the third IP:port number; making a determination to handover the media session from the first IP:port number to the third IP:port number; in response to making the determination, transmitting a third media stream using the third IP:port number as a source IP address and source port, and (ii) using the second IP:port number as a destination IP address and destination port; and receiving a fourth media stream from the second IP:port number.

TL;DR: The Silk Road of the Sea is a famous and fabled trade route connecting China with West Asia and Europe as mentioned in this paper, but has attracted much less attention that its overland counterpart.
Abstract: The overland Silk Road linking China with West Asia and Europe is a famous and fabled trade route. The sea route that was its alternative was arguably more significant, both historically and economically, and holds the greatest potential for understanding the great movements of people, ideas and goods in Asia. With its teeming port cities and huge vessels carrying exotic luxuries along with everyday commodities such as iron and fish oil, the Silk Road of the Sea is equally glamorous but has attracted much less attention that its overland counterpart.

TL;DR: In this article, the authors examined the emissions from ships at berth in the Port of Bergen in Norway and estimated the cost of these emissions at between €10 m and €21.5 m per year.
Abstract: This paper examines the emissions from ships at berth in the Port of Bergen in Norway. As well as estimating the quantity of emissions, we look at estimates of the external costs of pollution and derive a cost for the pollutants emitted by the ships at berth in Bergen. The cost of these emissions is estimated at between €10 m and €21.5 m per year.
TL;DR: In this article, the authors investigated climate change and the adaptation strategies of ports, with a special focus on port infrastructures and the day-to-day operational impacts and found that effective adaptation solutions are not just about physical layouts and engineering projects, but the need to fundamentally transform the current management and planning practices of ports.
Abstract: Being nodal points along supply chains, ports affected by climate change would create substantial costs to the global economy and welfare, and thus it is extremely important to ensure that ports can develop effective adaptation strategies. However, there are many uncertainties, as the dynamics between climate change and ports can diversify between different regions. Against this background, through exploratory case studies of four ports in Australia, this paper investigates climate change and the adaptation strategies of ports, with a special focus on port infrastructures and the day-to-day operational impacts. Research findings indicate that, while port managers recognize climate change as an issue which requires closer attention, adaptation strategies have remained segregated and piecemeal. This highlights the fact that effective adaptation solutions are not just about physical layouts and engineering projects, but the need to fundamentally transform the current management and planning practices of ports. It is a timely reminder to port policymakers and managers on the need to refine how effective decisions should be made for the challenges posed by climate changes in the future. In this regard, further research on this topic is urgently required.
TL;DR: In this article, the authors study container port competition for transshipment cargo in duopoly market and develop the linear container handling demand function which incorporates transshipments traffic, and apply a non-cooperative two-stage game to a vertical-structure seaport market with ports as upstream players and shipping lines as downstream players.
Abstract: The purpose of this paper is to study container port competition for transshipment cargo in duopoly market. We develop the linear container handling demand function which incorporates transshipment traffic, and apply a non-cooperative two-stage game to a vertical-structure seaport market with ports as upstream players and shipping lines as downstream players. The drivers behind port competition are explained through existence of the unique Nash equilibrium which incorporates shipping lines’ port call decisions and ports’ pricing strategies. A port collusion model and social optimum model are then analysed for further insights, and a numerical simulation is conducted to demonstrate the results.

TL;DR: In this paper, a structural equation model was used to assess the level of supply chain integration of seaports and the relationship to port performance, and the results indicated that the integration of SEAPorts into supply chains has a positive impact on both the effectiveness and the efficiency of SEaport performance, while SEAPORTS which do not integrate with their supply chains have a lower level of performance.
Abstract: Purpose – The changing role of seaports in supply chains has been the subject of extensive research in the recent literature. The strategic development of seaport terminals, responding to the need for closer integration into supply chains, invites a more detailed examination of the influence of the supply chain structures on seaport performance. Therefore, this paper aims to investigate the effects of supply chain structures, especially the degree of integration of seaports into supply chains, on seaport performance.
Design/methodology/approach – The parameters for a structural equation model were identified in the first instance from the supply chain and seaport operations and management literature. The structural equation model itself was then devised, and subsequently refined, using data from Korean seaport terminal operators, shipping companies and freight forwarding companies. The structural equation model was used to assess the level of supply chain integration of seaports and the relationship to port performance.
Findings – The results indicate that the integration of seaports into supply chains has a positive impact on both the effectiveness and the efficiency of seaport performance. In addition, antecedents to seaport supply chain integration are identified; these suggest that a strong orientation to supply chain integration within a port operating company enables the company to adopt and implement a strategy that integrates functions within the port and with other upstream and downstream organisations.
Research limitations/implications – As the field data were geographically limited to one country, extending the findings of this study to other geographical areas may not be possible, although the approach taken, using the structural equation modelling technique, should be transferrable elsewhere. Cross-validation of the model would widen its applicability to other areas. The paper provides a framework that allows other researchers to examine the level of integration of ports into supply chains.
Practical implications – The potential benefits of closer integration of seaports into supply chains are shown with supply chain integration having a positive effect on port performance. Seaports which do not integrate with their supply chains have a lower level of performance. Thus, enhanced port performance accruing from closer integration would have positive implications both for port and terminal managers and for other supply chain participants.
Originality/value – This study, for the first time, empirically examines the impact of the integration into supply chains of seaports on their performance. This is achieved by the development of a structural equation model which is then tested in the field, thus extending the existing literature which is largely conceptual or descriptive.
TL;DR: In this article, the authors identify and identify quasi co-located reference signal ports from downlink control information, such as CSI-RS and CRS ports, and perform channel estimation and/or time/frequency synchronization using the identified large scale properties.
Abstract: Methods and apparatuses indicate and identify quasi co-located reference signal ports. A method of identifying by a UE includes identifying, from downlink control information, a CSI-RS port that is quasi co-located with a DM-RS port assigned to the UE. The method includes identifying large scale properties for the assigned DM-RS port based on large scale properties for the CSI-RS port. The method includes performing channel estimation and/or time/frequency synchronization using the identified large scale properties for the DM-RS port. Another method for identifying by a UE includes identifying, from downlink control information, a CRS port that is quasi co-located with a CSI-RS port configured for the UE. The method includes identifying large scale properties for the configured CSI-RS port based on large scale properties for the CRS port. The method includes performing channel estimation and/or time/frequency synchronization using the identified large scale properties for the CSI-RS port.

TL;DR: In this paper, the authors investigated the market-based policy on pollution control in a region with multiple ports and found that in the absence of inter-port coordination, pollution spillover and interport competition can lead to distorted pollution taxation and emission constraints.
Abstract: This paper investigates the market-based policy on pollution control in a region with multiple ports. Although the fraction of in-port pollution is modest compared to at-sea emission, port pollutions generally occur near populated areas and have a higher impact on public health. Most of the studies on maritime pollution control have focused on technical designs and operating issues over deep sea shipping. In addition, while pollution from a port's operation may spread out and has influence over a wider region, few studies have analyzed emission control across ports. This paper aims to complement this stream of research by examining the behaviors of ports and port users (i.e., shippers and shipping lines) if a certain incentive or disincentive policy is implemented. Our investigation reveals that in the absence of inter-port coordination, pollution spill-over and inter-port competition can lead to distorted pollution taxation and emission constraints. As a result, there will be excessive pollution and sub-...
TL;DR: Appropriate tailor of the proposed SD based methodology can stimulate security–economic quantitative analysis in a wider range of port context, thus promoting effective implementation of security measures.
Abstract: Policy variables, such as security levels at seaports, affect port efficiency in a non-linear way while other factors affecting efficiency at ports such as a number of berths, the area of port yard, and the number of port labors have linear structural relation. Ensuring a certain level of regulations can increase port efficiency, while an excess of the level may result in the reverse of these gains. Addressing seaport-related issues is not a simple undertaking because a seaport is regarded as a system-of-system, which is both difficult to understand and to model. Therefore, studies that adequately analyze the overall dynamic of a port complex in terms of security concerns have been seen insufficient, leaving a significant research gap to fill in. To analyze the relationship between seaport security levels and container volumes, this study adopts the method of System Dynamics (SD). Use of the SD can demonstrate the benefits of simulations, such as suggesting the visual causal loops among evaluation factors, representing the several sub-models, and enabling various forms of analysis, such as the base model, optimistic scenario model, and pessimistic scenario model. As a result of simulation, the impacts on handling container cargo volumes in Korea due to the increasing level of security is estimated at 2,770,000 TEUs by the year 2015 and 3,050,000 TEUs by 2020. Appropriate tailor of the proposed SD based methodology can stimulate security–economic quantitative analysis in a wider range of port context, thus promoting effective implementation of security measures.
