Making the Australian flag fleet efficient: dysfunctional policy processes and the 'play of power'

In 1997 the Australian government introduced reform measures aimed at improving the efficiency and cost effectiveneess of the Auistralian maritime sector. These measures are part of an ongoing reform programme initiated in the early 1980s; but despite concerted efforts by a succession of governments and the payout of high labour redundancy costs the problems of inefficiency, high costs and low profitability persist. This paper focuses on the structure and mechanism of the policy making processes that have attempted to deal with the problem of making the Australian national flag fleet efficient and competitive. It does so because it is a fundamental tenet of the paper that it is the process of policy making that so frequently—if not invariably—determines policy content and outcomes.     

Asian hub/feeder nets: the dynamics of restructuring

The emergence of hub/feeder networks in the Singapore-Japan corridor through the 1970s and 1980s reflected not only the rapid growth of containerized cargo in regional Southeast and East Asia but also the exceptional importance of Far East/transPacific and Far East/Europe mainline shipping services in structuring these networks. This paper argues that the mid-1990s is a defining moment in the restructuring of these networks; that the period represents, in fact, a convergence of a number of different though related trends impacting on the regional shipping market. More particularly, continuing high growth rates of containerized cargo have not only spawned new ports but have also increased the proportion of ports handling threshold volumes of containers for which mainline calls, rather than handling thfeeder operations, are justified. Further, the quite dramatic retionalization of already large container shipping lines into mergers and alliances bestows a new level of market power that is able to underwrite major changes in shipping schedules, port rotations and feeder linkages. This paper speculates that these developments are generating, and will continue to generate new, hierarchically organized port/shipping networks in which high order networks will include high efficiency/high cost operations; and lower order networks will include a mix of hub and direct-call ports that will focus on different market segments.     

Marine log transportation and handling systems in british columbia: Impacts on coastal management

Abstract

Over 90 percent of British Columbia's annual log harvest enters into complex water‐based systems of transportation, storage, and handling. These systems have considerable impacts on a wide range of coastal resources and uses. A number of site‐specific conflicts have arisen between forestry and preexisting or emerging values including fisheries, mariculture, recreational boating, and harbor redevelopment. Specific data on the impacts leading to conflict are often fragmentary. However, concerns about highly valued and fragile areas‐particularly estuariesalong with industrial concerns regarding log losses and handling efficiency, have prompted changes in log handling. These include moves to dryland sorting, log bundling, and a redistribution of forestry activities in estuaries to accommodate other values. Conflict adjustments and responses have in the past been largely ad hoc and attempted in a jurisdictional vacuum concerning control of coastal management. A more inclusive strategy is now slowly emerging, which involves the coordinated participation of federal, provincial, and industrial interests.

Safety outcomes of internationalization of domestic road haulage: a review of the literature

Abstract

The European Union (EU) promotes gradual lifting of restrictions on foreign hauliers involved in domestic road transport of goods (cabotage), and a major deregulation was scheduled in 2014. Due to complaints from several member states facing competition from new EU-countries with lower labour costs, this process was postponed until 2015. An important aspect related to such a deregulatory reform includes potential consequences for transport safety and accident risk factors. The main aims of the current paper are therefore to examine the potential transport safety outcomes of increasing internationalization of domestic road haulage, and to examine potential accident risk factors of foreign hauliers. This is done by reviewing the research literature. This paper shows that the heavy goods vehicle (HGV) accident risk varies with a factor of up to 10 in European countries, and that the accident risk of foreign HGVs is approximately two times higher than that of domestic HGVs in the studied European countries. The paper points to several risk factors and concludes that better data on accident risk and risk factors must be gathered in order to enable European authorities to correctly analyse and respond to this important traffic safety challenge.     

Productivity of first-generation container terminals: Sydney, Australia

In 1969 the first of Sydney's purpose-built container facilities in Port Jackson, the Seatainer terminal, became operational. Later, in 1973, the second terminal at Glebe Island, a common-user facility, shared the task of handling the container traffic for much of eastern Australia until the development of the new facilities in Botany Bay. The two terminals differed in almost every respect except their inner-city locations and restricted sites. This paper explores these differences and their implications for terminal productivity. It examines some of the structural characteristics of the container trade and traffic and defines vessel time profiles and container handling rates for operations over the sample years 1977, 1979 and 1981. The paper establishes that there were remarkably similar productivity characteristics at the two terminals, despite their significant characteristics, but it also reveals the relatively high proportion of vessel alongside time or time spent at the berth that was idle, non-working or unproductive.     

Containerization in ports of Third-World Asia: an overview of present patterns and the direction of future growth

Although containerization in Third World Asian ports may not conform to the 'usual' model of containerization in developed countries the region represents a significant generator of container tonnage. Moreover, despite considerable intra-regional differences in throughput productivities, some of the ports are achieving efficiencies and productivities markedly higher than those in well established ports in Western countries. The region has been characterized, too, by strong patterns of mainline/feeder interdependencies. This paper reviews the status of containerization in Third World Asia and suggests that major changes, reflecting a variety of factors, are likely by 1990.     

Swimming for survival: A role of phytoplankton motility in a stratified turbulent environment

We investigate a role for vertical migration in stratified coastal water, where the swimming speed is generally significantly less than the typical turbulent fluctuations in a tidally-mixed bottom layer. In our modelling approach we use a k- turbulence model to describe the physical forcing, a Lagrangian random walk model to describe the vertical displacement of individual cells in response to turbulence and due to cell motility, and a phytoplankton growth model to direct the swimming behaviour of the phytoplankton according to their light and nutrient requirements. The model results show how the cells form a stable subsurface chlorophyll maximum (SCM) at the base of the thermocline where episodic tidal turbulence causes erosion of part of the SCM biomass into the bottom mixed layer (BML). We then focus on the question of whether an ability to swim (weakly, compared to typical bottom layer turbulent intensities) provides any advantage by allowing return to the SCM. Our results show that tidal turbulence in the BML helps both motile and neutrally-buoyant cells by periodically pushing them into the base of the thermocline. Motile cells then have the advantage that they can swim further into the thermocline towards higher light which also reduces the likelihood of being re-mixed back into the BML.     

Explaining obesity with urban form: a cautionary tale

In recent years, there has been a dramatic increase in studies exploring associations between the built environment and obesity. Many studies have found that built environment characteristics, such as high-density land developments, mixed-land uses, and connected street networks, are associated with lower rates of obesity. However, depending on the research field and the researcher, how one specifies the experimental model and how sociodemographic characteristics of the population are defined and included in the model has led to different policy conclusions and implications. This is not a surprising observation; however, it is one that does seem to have been lost in current discussions. This article highlights several data-processing, model-specification, and model-estimation factors that should be comprehensively considered in studies of the built environment and obesity. Empirical results based on data from Atlanta, GA, USA, illustrate that the association between the built environment and obesity is sensitive to how age, income, and educational attainment are included in the model. Also, a detailed examination of land-use-mix measures shows that it is difficult to create this measure and that results are sensitive to the treatment of missing values. Models that distinguish between overweight and obese individuals are shown to provide richer insights into the associations among obesity, built environment, and sociodemographic characteristics for the Atlanta area. The article concludes by offering modeling recommendations for future studies.
