Antimutagenicity, cytotoxicity and composition of chlorophyllin copper complex.

The preparation of chlorophyllin copper complex (CCC), shown to be a tumor promoter in an animal model (Nelson, R.L. (1992) Chlorophyllin, an antimutagen, acts as a tumor promoter in the rat-dimethylhydrazine colon carcinogenesis model. Anticancer Res., 12, 737-740), also inhibits the activities of direct- and indirect-acting mutagens in the Salmonella assay and exhibits cytostatic and cytocidal effects toward myeloma cells. Data from elemental analyses, spectrophotometry and reversed-phase high-performance liquid chromatography indicate that CCC preparations generally used in antimutagenic/anticarcinogenic experiments are variable, complex mixtures of structurally distinct porphyrins lacking copper in some instances. This variability of the composition may be a cause for the differences reported for the tumor promotion activity of CCC.

What knowledge-accessing modes tell administrators about interdisciplinary crises and conflicts.

In hospitals administrators work with two major groups of medical professionals: physicians and nurses. Together, these three groups of professionals are primarily responsible for the care of patients. The quality of the service they provide is dependent on the working relationships among these disciplines. Potentially, the more harmony among administrators, physicians, and nurses, the better care patients can receive. The research reported in this article addresses the issue of interdisciplinary misunderstanding among these groups of professionals. The research was premised on the assumption that hospital administrators, physicians, and nurses differ in the way they access knowledge. That is, administrators, physicians, and nurses access knowledge in dissimilar ways and, by doing so, set the stage for crises and conflicts. Using a standardized instrument to assess knowledge-accessing modes, data were collected from samples of health administration, medical, and nursing students. The data indicated that the three groups did differ in the way they accessed knowledge. The individual discipline profiles generated from the data also revealed a finding common to the three disciplines, a finding may help resolve a very real problem for hospital patients. Based on the research results, the article discusses ways that administrators may be able to prevent crises and conflicts and enhance harmonious relations among the three disciplines, and thereby improve patient care. Avenues for further research are also suggested.

Faculty ways of knowing: the crux of nursing curricula.

The authors, using the narrative form, examine three epistemological structures that are found in nursing curricula. Those fundamentally different approaches of knowledge acquisition are portrayed and discussed by the director and three staff members from a fictitious nursing school. Although faculty members naturally tend to adhere to their own embedded view of the way one learns, the authors stress the need for judicious blend of the three epistemic orientations when developing nursing curricula.

An analysis of the epistemic orientation of first- and third-year students in a physiotherapy program.

Previous research has demonstrated that practitioners within the same profession share a common approach to knowledge acquisition and transmission. A search for the identification of this common approach to knowledge in physiotherapy was undertaken using the Epistemic Orientation Model. The research reported was premised on the assumption that students admitted to physiotherapy programs in Canada possess an epistemic orientation that is similar to the epistemological structure of the knowledge base considered important to the program. Using a standardized instrument known as the Knowledge Accessing Modes Inventory (KAMI) to measure epistemic orientation, data were collected from a sample (N = 59) of first- and third-year students registered in a physiotherapy program in a central Canadian university. The data indicated that a high degree of association exists between the epistemological structure subsumed in the knowledge base deemed essential to gain admission to the program and the dominant rational epistemic mode of the practitioners-to-be. Based on the results, the article examines the usefulness of the epistemic orientation concept on activities within the profession. Implications for professional development are noted and avenues for further research are suggested.
