title: Dynamic equilibrium in applied geomorphology: Two case studies

authors: Douglas, Ian

abstract: Engineering works and agricultural activity which change the relationship between rainfall and river flow lead to modifications of river channels with attendant erosion and deposition problems. In the Swiss Jura Lakes area, the natural flooding of the River Aare became such an acute problem by the mid-nineteenth century that extensive engineering works were carried out to alleviate flooding. The land thus reclaimed became a valuable agricultural asset, but the fall of the water table following removal of the annual flood risk, led to a fall in the level of the land as peat was changed into humus. Renewed flooding occurred. The natural readjustment following the first series of flood alleviation works reproduced the original problem and a second series of engineering works has had to be undertaken to remedy the situation. On the Belgian coast, harbour construction and the spread of buildings over the sand dunes have resulted in severe beach erosion in the eastern seaside resorts. Extensive engineering works have had to be undertaken to restore the beach. These examples illustrate how man's challenges to nature are often recurrent phenomena, and how the alteration of one aspect of the physical environment may lead to a succession of readjustments. Each phase of engineering activity may be considered a break in natural equilibrium, and each period of natural erosion or deposition a trend towards a new equilibrium.

title: Views on clinical trial recruitment, biospecimen collection, and cancer research: population science from landscapes of the Haudenosaunee (People of the Longhouse).

authors: Haring, Rodney C.

subjects: American Indian

abstract: Biomedical research in culturally distinct communities is often a challenge. Potential barriers to participation occur because science is presented in a format that lacks cultural acknowledgement. Investigations may also fail to showcase beneficial relevance to the communities or include them in true partnership. The history of biomedical research within Native American societies has been complicated by these issues. Historical trauma among many Native groups sometimes transcends into contemporary challenges in both recruitment to and participation particularly in biobanking research. The participants for this study included members of the Haudenosaunee, the People of the Longhouse. Native Americans, including the Haudenosaunee, endure some of the worst health disparities in the country. These include high rates of cancer, obesity, and diabetes which may be linked at least partially to genetic predisposition. Results from a Haudenosaunee urban population shared response on ways to improve recruitment strategies for biospecimen, cancer, and other health-related clinical trials. Mixed methods approaches were used, and community responses indicated the importance of creating trust through respectful partnership; promoting culturally appropriate recruitment materials; the need for a greater understanding of consenting and signature processes; the necessity for concise summary sheets; and a desire to have information that community member understand. Discussion items also include international Indigenous perspectives to biobanking and genetic-related health disparity research.

title: Tāwharautia Aotearoa

authors: Maxwell, Te Kahautu

abstract: Tāwharautia Aotearoa was composed in opposition to the National Governments attempt to remove Section 9 of the Principles of the Treaty of Waitangi which would give the Government power to sell State assets. Performed by Ōpōtiki Mai Tawhiti at the Te Matatini World Championship Kapa Haa Competition 2013.
