title: Risk committee, corporate risk-taking and firm value

authors: Bhuiyan, Md. Borhan Uddin

abstract: We empirically examine the impact of the stand-alone risk committee on corporate risk-taking and firm value. We argue that the existence of a stand-alone risk committee enhances the quality of corporate governance which results in improved investor protection by reducing corporate risk-taking and enhancing firm value. We find several measures of risk-taking decline significantly for firms that have a stand-alone risk committee compared with firms that have a joint audit and risk committee. We also find that the presence of a stand-alone risk committee is positively associated with firm value. The evidence is consistent with the proposition that the firms with a stand-alone risk committee can effectively evaluate potential risks and implement a proper risk management system.

title: Anthropogenic relief features in tropical northern Australia: A physical and chemical analysis of the Weipa shell mounds

authors: Fanning, P

abstract: Large mounded deposits of shell are prominent archaeological features across much of the north Australian tropical coast. Many of the shell mounds are composed almost entirely of the bivalve Anadara granosa (Linnaeus 1758), a food source for Aboriginal people in the past. They are identified in the field by their distinct mounded topographic form and the unique vegetation community growing on them. A relatively long history of inquiry into the nature and significance of the shell mounds has focused primarily on analysing the shell component as clues to Australian Aboriginal coastal economies in the past. This paper presents results of new analyses on the non-shell sediments of mounds located near Weipa in far north Queensland, examining the physical and chemical signatures of deposi- tional and post-depositional processes with a view to obtaining insights into how the mounds formed and for what purposes, and how their morphology, structure and content may have changed since they ceased accumulating. We also consider how such changes might relate to past and present environmental conditions. The mounds we studied are primarily located on topographic high points, such as cliffs, hillslopes and beach ridges, though a proportion are located on estuarine floodplains at low elevations. Terrestrial Laser Scanning (TLS) of a sample of 51 shell mounds demonstrates substantial variation in mound size and shape, and suggests patterning in mound form re- lated to age as well as position on the landscape. However, radiocarbon chronologies demonstrate that the mounds do not conform to a model of linear formation of a shell deposit, suggesting mound histories are variable in both the nature of shell deposition as well as post-depositional processes. Soil physical and chemical analyses indicate that post-depositional diagenetic alteration has strongly influenced the present day composition and form of the shell mounds, in particular the accession of carbon and silica to the mounds by environmental burning aided by strong leaching under seasonal high rainfall conditions. As such, mound chemistry is more likely to reflect modern environmental conditions rather than provide an archive of the past.

title: Indigenous Peoples and the Protection of Their Secret Knowledge: A Promising Pathway Ahead

authors: Masoni, Claudia

abstract: This work focuses on the intangible, secret aspects of indigenous peoples’ cultures and how such secret information is protected by indigenous guardians or holders. This is because much of indigenous culture is imbued with spiritual significance for indigenous peoples and, consequently, it is not made available to the rest of the community and the world at large.
This thesis examines the reasons why it is important to preserve indigenous cultures and secret practices that today survive in indigenous communities. The thesis demonstrates that secrecy is seen as essential to the preservation of indigenous secret knowledge. Indigenous guardians are responsible for the preservation of the information, and they commonly use secrecy to preserve the knowledge and, when they share it, they choose limited, confidential circumstances to do so. This work argues that it is important to make reasonable space in the existing body of laws which have so far failed to effectively protect indigenous secret practices and information. The case study described in this thesis helps understand how states are currently trying to listen, understand and accommodate indigenous claims brought forward at the national and international fora. The thesis reviews the legal protection currently available to indigenous secret knowledge in national and international law. The first 6 chapters introduce indigenous cultures, holism and indigenous peoples and international law, and chapter 7 describes the New Zealand case Wai 262 and the recommendations given by the Waitangi Tribunal. The remaining chapters analyse indigenous cultures and intellectual property laws, identifying gaps in the existing mechanisms for protection and underlining why, as of today, intellectual property law does not guarantee adequate protection to indigenous secret knowledge. The last chapter analyses the law of breach of confidence as a possible instrument to safeguard indigenous secret information and the duty of care performed by indigenous guardians in preserving such knowledge. It argues that the existing law of confidentiality can usefully evolve to protect cultural secret information as a growing category in its own right and that indigenous secret information can find protection as confidential information.
