Anthropometric fractionation of body mass: Matiegka revisited

In a group of 699 Belgian nursing professionals, we estimated body composition using the four-component anthropometric model, relying on the equations originally formulated by Matiegka in 1921 and later revised by Drinkwater and colleagues. We estimated muscle mass using the more recent formula proposed by Martin and co-workers. A discrepancy was noted between estimated total body mass and 'assessed' mass, suggesting erroneous estimations of the components.     

Communication Ethics and Ethical Culture: A Study of the Ethics Initiative in Denver City Government

This article examines the work of the ethics initiative in the City of Denver to see how talk about ethics contributes to an ethical culture. By paying particular attention to the communication in the city's Code of Ethics, ethics training discussion, employee interviews, and formal documents relaying the Board of Ethics' views, we show how ethics emerges within communication. We argue that the emergent quality of ethics is dialogically refined in communication. For practitioners and officials interested in advancing organization-wide ethics training, we urge pursuing dialogical means so that people can negotiate among competing interests to shape future policy and action reflective of their ethical concerns.     

Increased learning observed in redesigned introductory biology course that employed web-enhanced, interactive pedagogy

Our Introduction to Biology course (BIOL 1010) changed in 2004 from a standard instructor-centered, lecture-homework-exam format to a student-centered format that used Web-enhanced, interactive pedagogy. To measure and compare conceptual learning gains in the traditional course in fall 2003 with a section of the interactive course in fall 2004, we created concept inventories for both evolution and ecology. Both classes were taught by the same instructor who had taught BIOL 1010 since 1976, and each had a similar student composition with comparable biological knowledge. A significant increase in learning gain was observed with the Web-enhanced, interactive pedagogy in evolution (traditional, 0.10; interactive, 0.19; p = 0.024) and ecology (traditional, -0.05; interactive, 0.14; p = 0.000009) when assessment was made unannounced and for no credit in the last week of classes. These results strengthen the case for augmenting or replacing instructor-centered teaching with Web-enhanced, interactive, student-centered teaching. When assessment was made using the final exam in the interactive course, for credit and after studying, significantly greater learning gains were made in evolution (95%, 0.37, p = 0.0001) and ecology (143%, 0.34, p = 0.000003) when compared with learning gains measured without credit or study in the last week of classes.
