Assessing the diurnal evolution of surface radiation balance over the western region of Tropical Atlantic Ocean using in situ measurements carried out during the FluTuA balance Project

In this work, the diurnal evolution of the radiation balance components over the tropical Atlantic Ocean is described and analysed. The analysis is based on measurements carried Out on board a Brazilian Navy ship during the observational campaign of the FluTuA Project (`Fluxos Turbulentos sobre o Atlantico`), from 15 to 23 May 2002. The observations indicated that the albedo responds its expected to atmospheric attenuation effects with a diurnal evolution similar to the Fresnel albedo. In general, the observed longwave radiation values agreed better with the estimated values obtained without longwave reflection. In agreement with the literature, the average surface emissivity was around 0.97. The net radiation, estimated from published equations for albedo, atmospheric transmissivity and surface emissivity, agreed with the observations, indicating that these parameters are representative of the radiometric properties of the air-sea interface in the region between Natal (6 degrees S, 35.2 degrees W) and the Sao Pedro and Sao Paulo Archipelago (1 degrees N, 29.3 degrees W).

Terrify and control: the politics of risk society

The article presents information on the idea of risk management. The origins of the contemporary constructions of risk are found in the seventeenth century, with the development of maritime insurance. In the context of maritime trading, risk came to be seen in terms of the balance between acquisitive opportunities and potential dangers and calculations of future loss of a ship or cargo. Today perceptions of risk affect our actions and strategies in areas of our life as diverse as health, parenting, crime prevention, recreation and travel. Public policy tends to be focused around risk avoidance and risk management, particularly in areas of child protection and aged care. While most of the discussions of risk have focused on risks as bads in society, risk has also been identified as a good. Risk is deemed a good when it challenges people to think differently and creatively. From a neo-liberal perspective risk opens up opportunities for unleashing of entrepreneurial capacity. In the context of the modernist commitment to the idea that people have the potential to control their own destiny, identification of threats and dangers can energize people to be adventurous. The discourse of risk has framed all the reports of the outbreaks of new strains of infection and includes instructions on how to recognize the risk assessments of its spread and instructions on how to avoid its spread.

Community language programs in Australian schools: policy at the crossroads

The linguistic situation in Australia today presents an intriguing case for sociolinguistic inquiries. Despite the recent waves of migration from non Anglo-Celtic regions, the majority of Australians today are primarily monolingual with English being the dominant language. More critical, perhaps, is the diminishing appeal of second language learning even among second generation speakers of the large ethnic communities. This is indeed ironic giving that prior to white settlement in Australia, the Aboriginal inhabitants were predominantly multilingual with more than 250 languages (and many of their dialects) spoken by the 300 000 original inhabitants at the time when Captain James Cook's ship reached Botany Bay in Sydney in 1770. Given the size of the post-War migration, it was not until 1987 that the Australian government adopted a formal national policy on languages becoming 'the first English-speaking country to have such a policy and the first in the world to have a multilingual languages policy' (Australian Alliance for Languages 2001: 2). This paper will discuss the historical context for multilingualism in Australia and the current trend in government policy and funding. It will provide insights into community language programs and the challenges of remaining viable and relevant in the current social and political climate. Statistical analyses will be used to highlight emerging trends and future prospects.

Playful learning : Melville's artful art in Moby-Dick

It remains one of the great ironies of American literary history that Melville's Moby-Dick struggled so long for critical and popular recognition. It is a peculiar text (but, then, so are Hawthorne's novels), a romance of the whale fishery that involves such explorations of language itself, of words, metaphor, symbol, allegory and the processes (and significance) of narrative construction. This article analyses its 'peculiarities' as fundamental indicators of Melville's 'playful art' to argue the usefulness of a concept of 'play' to its appreciation. That Moby-Dick is allusive and multi-layered is well known. But for what apparent purpose and to what effect? Here, a claim is made that Melville simultaneously constructs and deconstructs meaning by demonstrating that things ('in complex subjects') never come simply or singly. The later Barthes and Derrida become part of this ship's crew and Moby-Dick is a postmodernist novel avant la lettre.

Victorian marine habitat mapping project

Deakin University along with the CRC for Coastal Zone, Estuary and Waterway Management, the Glenelg Hopkins CMA and the Marine & Coastal Community Network have formed a partnership to map the benthic habitats at 14 sites across approximately 5% of Victorian State waters. The project is funded through the Federal Government by the Natural Heritage Trust and brings together expertise from universities, government agencies and private enterprise. We will be using hydro-acoustic sonar technologies, towed video camera and remotely operated vehicles to collect information on the types of substrate and bathymetry to derive habitat maps. The coastal fringe of Victoria encompasses rich and diverse ecosystems which support a range of human uses including commercial and recreational fisheries, whale watching, navigation, aquaculture and gas development. The Deakin lead initiative will map from the 10-metre contour (safe ship passage) to the three nautical mile mark for selected regions and will provide a geospatial framework for managing and gaining better understanding of the near-shore marine environment Research products will be used for management, educational and research purposes over the coming years.

Drawing lines in the sea : the laws that govern traffic on the world’s oceans can be as difficult to shape as water

Since World War II, however, the term has increasingly referred to law enforcement operations, as a means to enforce trade sanctions, to prevent the movement of weapons of mass destruction (WMDs), and particularly in the Caribbean Sea, to prevent the smuggling of illicit drugs. Such ambiguity should allow flexibility when deciding whom should be targeted, as well as allowing states with veto powers in the UN Security Council, which may legitimately ship nuclear weapons and materials, to avoid being targeted as long as they do not export WMDs to rogue states or non-state groups or individuals.2 The ISPS Code was created under the auspices of the International Maritime Organization (IMO) and is part of the 1974 Safety of Life at Sea Convention (SOLAS) concerning the safety of merchant ships.

Prayers and pastures : Moidart emigrants in Victoria, 1852-1920

In 1852 thirty-seven Households from working class Catholic backgrounds emigrated from Moidart, Scotland, to the Colony of Port Phillip in Australia. This study personalises and contextualises the experiences of three generations in Scotland, on board ship and in Victoria concluding that upward mobility and economic security were achievable.

Government involvement in entrepreneurship and new business creation in Australia : a quantitative analysis of public perceptions and opinions

In order to determine the range of Australian perceptions on new venture creation at the end of the decade of the 1980s, and in particular attitudes towards government involvement in fostering entrepreneurship, a major quantitative study was conducted. The survey involved more than 1500 Australians in face-to-face interviews (300 in each mainland capital city) chosen on a random basis.

An analysis of the data provides an assessment of the Australian general public&s perceptions in three key areas: their understanding of the word 'entrepreneur' their rating of importance of new venture creation; their belief in government involvement in fostering new venture creation.

It is believed to be the first study attempting to quantify an entire nation&s perceptions in three areas vital to creators of national economic and industry policies.

New Zealand and its competitors in the knowledge economy

In the US, Australia, the United Kingdom, Canada, Finland, Ireland and other countries, the growth of the Internet and other related new technologies have become the catalyst for the creation of ‘knowledge economies’. The new information and communication technologies have created global markets for goods and services. Countries that have encouraged their people through education and life-long learning and by investing heavily in research and development (R&D) are well positioned to take advantage of these new global markets. Along with globalisation has come the death of distance. Thanks to the Internet, New Zealand is no longer remote from the rest of the world.

But New Zealand’s economy is still too dependent on producing commodities for export. While efforts over the last fifteen years to diversify markets have been very successful, we still need to expand our limited range of products. We must take the next important step and transform New Zealand from a pastoral economy into a knowledge-driven economy. For New Zealand, the Internet is the modern equivalent of the freezer ship that revolutionised our economy last century. If New Zealanders do not seize the opportunities provided by the knowledge economy, we will survive only as an amusement park and holiday land for the citizens of more successful developed economies.

This article puts New Zealand into world perspective by assessing its knowledge economy benchmarks against its competitors. It outlines the theoretical background to ‘‘new growth theory'' and delineates the lessons of that theory, especially for New Zealand. It treats the key issues for New Zealand’s emergence as a knowledge economy, including education, the M ori dimension, immigration, research and development, venture capital, export policy and telecommunications regulation.

Maritime archaeology and trans-oceanic trade : a case study of the Oranjemund Shipwreck Cargo, Namibia

Routine sand dredging for alluvial diamonds at Oranjemund on the southern coast of Namibia exposed remnants of a long forgotten Portuguese merchant ship believed to have wrecked in the 1530s. The rescue excavations yielded over 40 tons of cargo consisting of thousands of gold and silver coins, tons of copper and lead ingots, and large quantities of ivory together with food refuse, part of personal possessions and the superstructure of the ship. This paper discusses the cargo from the shipwreck. The varying provenances show that overland inter-and intra-regional networks fed into the maritime trade between Europe and the Indian sub-continent. As such, the wreck is a lens through which we can view what was happening on the seas as well as on land. Finally we consider wider issues raised by this discovery relating to the protection and management of such material wherever it may be found in future.

Supporting personalised content management in smart health information portals

Information portals are seen as an appropriate platform for personalised healthcare and wellbeing information provision. Efficient content management is a core capability of a successful smart health information portal (SHIP) and domain expertise is a vital input to content management when it comes to matching user profiles with the appropriate resources. The rate of generation of new health-related content far exceeds the numbers that can be manually examined by domain experts for relevance to a specific topic and audience. In this paper we investigate automated content discovery as a plausible solution to this shortcoming that capitalises on the existing database of expert-endorsed content as an implicit store of knowledge to guide such a solution. We propose a novel content discovery technique based on a text analytics approach that utilises an existing content repository to acquire new and relevant content. We also highlight the contribution of this technique towards realisation of smart content management for SHIPs.

Developing a simple, rapid method for identifying and monitoring jellyfish aggregations from the air

Within the marine environment, aerial surveys have historically centred on apex predators, such as pinnipeds, cetaceans and sea birds. However, it is becoming increasingly apparent that the utility of this technique may also extend to subsurface species such as pre-spawning fish stocks and aggregations of jellyfish that occur close to the surface. In light of this, we tested the utility of aerial surveys to provide baseline data for 3 poorly understood scyphozoan jellyfish found throughout British and Irish waters: Rhizostoma octopus, Cyanea capillata and Chrysaora hysoscella. Our principal objectives were to develop a simple sampling protocol to identify and quantify surface aggregations, assess their consistency in space and time, and consider the overall applicability of this technique to the study of gelatinous zooplankton. This approach provided a general understanding of range and relative abundance for each target species, with greatest suitability to the study of R. octopus. For this species it was possible to identify and monitor extensive, temporally consistent and previously undocumented aggregations throughout the Irish Sea, an area spanning thousands of square kilometres. This finding has pronounced implications for ecologists and fisheries managers alike and, moreover, draws attention to the broad utility of aerial surveys for the study of gelatinous aggregations beyond the range of conventional ship-based techniques.
