Evolution Of Chemical Contaminant And Toxicology Studies, Part 2- Case Studies Of Selenium And Arsenic, Glennys O'Brien, Dianne Jolley, Robert John Morrison

As the second of a two part series discussing the evolution of the field of environmental toxicology, this paper presents two case studies: selenium and arsenic. Developments over several decades in the understanding of the behaviour of arsenic and selenium in different chemical forms in various compartments of the environment are discussed. Selenium was initially thought to be toxic, but later investigations showed it to be an essential micronutrient with a variety of biochemical functions, and, importantly, that there is a very narrow gap between the essential and the toxic body burden. Arsenic, on the other hand, has not yet ...


An Archaeology Of Historical Reality?: A Case Study Of The Recent Past, Alistair Paterson, Nicholas Gill, M.J. Kennedy Jan 2003

An Archaeology Of Historical Reality?: A Case Study Of The Recent Past, Alistair Paterson, Nicholas Gill, M.J. Kennedy

An Aboriginal elder, an archaeologist and a geographer report on an interdisciplinary project about colonial-era settlement in the Murchison and Davenport ranges in the Northern Territory. Oral history, physical evidence and historical records reveal a distinct central Australian cultural landscape and show that archaeology can do more than merely exhume material to support historical 'realities'. This project provides new or improved understandings of (1) colonial technology in pastoral ventures, (2) continuity and change in Aboriginal life following European arrival, (3) social behaviour in colonial settings, and (4) alternatives to Eurocentric Australian histories.

To support the sharing and reusing of well-defined knowledge among knowledge management systems, it is useful to use standardised formalisation. It is also common effort to difficulty of knowledge acquisition known as knowledge acquisition bottleneck. In this paper investigates the feasibility of using techniques in case-based reasoning of artificial intelligence for the knowledge acquisition phase in knowledge management systems. The need of an ontological approach of the semantic web for well-defined set of domain knowledge is proposed in order to avoid knowledge acquisition bottleneck. Our viewpoint of this approach is that the ontology-driven mechanism allows us to provide standardised structured ...


Schema Construction Among Pre-Service Teachers And The Use Of It In Mathematics Teaching: A Case Study, Mohan Chinnappan Jan 2003

Schema Construction Among Pre-Service Teachers And The Use Of It In Mathematics Teaching: A Case Study, Mohan Chinnappan

Faculty of Social Sciences - Papers

Recent developments about cognitions underlying mathematical learning are beginning to suggest that the activation and appropriate use of prior knowledge by students is, to a large measure, controlled by the quality of organisation of that knowledge. Thus, teaching needs to support the construction of well-connected mathematical knowledge. An important assumption here is that teachers need to construct a repertoire of subject-matter knowledge that is rich and well connected before they can help their students build similar mathematical knowledge. Thus, mathematics knowledge building is an important issue in teacher preparation programs. This paper reports on a study about the knowledge state ...
