This article presents trends in published MIS research for an 11 year period, 1993-2003. It is an update of a previous article in CAIS (Volume 11, Article 16) that covered the period 1993-1997. All of the articles in seven mainstream MIS journals were examined in terms of subjects researched and methodologies employed to conduct research. Recent trends are presented and compared to those of the earlier study. The results clearly indicate the focus of efforts of researchers on information system usage and information systems resource management. The survey methodology still appeals to many researchers but increases in the use of mathematical models and laboratory experiments is an indication that the field is attaining maturity by using more rigorous research methods.

We examine the state of ocean energy in 2009 and consider its potential as a source of renewable energy. We provide a background on the current state of technology and commercial development, and examine the implications for law and policy of the re-emergence of ocean energy as a source of renewable energy in 2009. In the 1970s much of the academic and policy literature highlighted jurisdictional uncertainty surrounding ocean energy under international law. Th is is not the case today. Although some questions remain with respect to navigation rights, most questions surrounding the nature and extent of coastal State jurisdiction in relation to ocean energy have been resolved by the 1982 United Nations Convention on the Law of the Sea. Instead we argue that one of the biggest challenges faced by ocean energy today is the uncertain state of regulation under domestic legal systems. We highlight issues requiring attention by policy-makers and legislators, including managing hazards to navigation, providing further fi nancial incentives for wide-scale commercialisation of this technology (such as increased research and development funding and feed-in tariff s) and managing ocean energy's relatively benign environmental impacts.

Unmanned aerial vehicles (UAVs), also known as drones, are used in scientific research and a diverse range of other applications across the globe. They are also being used increasingly for scientific research in Antarctica and to a lesser extent by tourists visiting the world's last great frontier tourist destination. Their use in scientific research in Antarctica offers many benefits to science and if used responsibly may be less invasive than other research techniques, offering a rich source of new scientific data. For tourists, UAVs also offer unique aerial photographic perspectives on Antarctica — the ultimate holiday snap shot. Concerns have been raised about the safety of drone use in the harsh and unpredictable Antarctic conditions, as well as possible environmental impacts. This paper considers these issues and the emerging regulatory response to drone use in Antarctica focusing on theAntarctic Unmanned Aerial Systems (UAS) Operator's Handbook, which provides guidelines to national Antarctic programmes on the use of UAVs in the Antarctic Treaty area, and the temporary ban on use of drones by tourists imposed by the International Association of Antarctica Tour Operators (IAATO). Both measures arguably constitute a good first response to this emerging issue, although more still needs to be done.
