Relationality and legitimacy : learning to negotiate meaningful research among aboriginal and non-aboriginal researchers

This paper describes the ethical issues involved when research is conducted in a Inuit context by non-Inuit researchers. It draws on the experience of a three-year participatory action research project in Nunavik. It describes the strategies and approaches deployed and adapted by the "Other" researchers to apply the principles of critical Indigenous methodologies. The paper is a reflection on our relationship with the research participants and stakeholders and how our approaches and actions facilitated or hindered their meaningful participation in and ownership of the research. Participants' feedback and reactions to the research process were elicited and are reflected in the paper. This article is of significance for researchers who are thinking of working in Aboriginal communities or other communities to which they are outsiders. While focusing mainly on the role of researchers and their approach, the paper also questions the challenge of bridging Western research practices and critical Indigenous research methods

Foundation Treatment of Embankment Dams With Combination of Consolidation and Compaction Groutings

Treatment of soft or weak foundation in a rockfill dam is of importance due to being susceptible to the large settlements, which may cause the dam body subjected to undesirable deformations and even, catastrophic failures. In this paper the stress- strain behavior of an under construction 58 m embankment dam in North-West of Iran, namely Gerdebin dam, and its soft and weak alluvial thick foundation has been assessed numerically. The effect of combination of consolidation and compaction grouting of the basement (as a remediation method) on the dam deformations and stress levels, is investigated. For this purpose, a finite difference based software (FLAC 2D ver. 4.00) has been used to evaluate the effects of the governing mechanical parameters on the dam body behavior. Results show that for certain values of the mechanical properties of the grouted zone, the dam body deformations reaches to the minimum level. The mechanical properties of the grouted zone materials are dependent on the grouting pattern. Hence, an optimized grouting pattern has been achieved for such a case problem. Such an optimized grouting pattern is already under the executing procedure at the dam site
