There is no doubt that nanoscience is a breathtakingly interesting area, and one of the most exciting in modern physical science. It is also clear that the path from science to technology is just beginning to emerge, and it is too early to say whether the impact of nanotechnology on society will be revolutionary or insignificant. But, as a rule, where there is new science, there is new technolo...

In the physical sciences a rigorous theory is a hierarchy of descriptions in which causal relationships between many general types of entity at a phenomenological level can be derived from causal relationships between smaller numbers of simpler entities at more detailed levels. The hierarchy of descriptions resembles the modular hierarchy created in electronic systems in order to be able to mod...

The political mobilization of indigenous peoples in the North American North has resulted in new guidelines, statements of ethical principles, and consultative processes for the conduct of scientific research. This article explores the history of large-scale physical science in the North, the development of ethical principles for research conduct in Canada and the United States, and the potenti...

This paper uses three case studies in order to examine the implementation of a policy of biological progress, initiated by the Rockefeller Foundation in the 1930s. In discussing the social and scientific goals of this research policy, the paper challenges views which have attributed to the Foundation's policy a direct irnpact upon the rise of molecular biology; i t also suggests that this polic...

Image fusion is a process of combining two or more images into an image. It can extract features from source images, and provide more information than one image can. Multi-resolution analysis plays an important role in image processing, it provides a technique to decompose an image and extract information from coarse to fine scales. In some practical forensic examinations (such as the cartridge...

Cultural competency training for health professionals is now a recognised strategy to address health disparities between minority and white populations in Western nations. In Australia, urgent action is required to "Close the Gap" between the health outcomes of Indigenous Australians and the dominant European population, and significantly, cultural competency development for health professional...

This research note presents data on the replication of a carefully planned intervention to increase the commitment of department chairs in the physical sciences to the hiring and career advancement of women. Three separate workshops for department leaders in chemistry, physics, and material science were held. Participants’ views regarding factors that affect attracting women candidates, the hir...
