Journal Supplement

Journal club as a supplement to the undergraduate biochemistry laboratory.

After purification of lysozyme, our biochemistry students write a research proposal that outlines a strategy for studying this enzyme after alteration by site-directed mutagenesis. Despite a literature search that yielded a wealth of background information, students were often overwhelmed by the assignment because they were not familiar with advanced techniques of protein analysis. We therefore...

Although substantial progress has been made over the past two decades in reducing child mortality, the fact remains that far too many children continue to die before their fifth birthday. A large proportion of these deaths—more than one-third—occur as a result of pneumonia, diarrhea, and malaria. Addressing these child killers in the communities where they occur is, therefore, critical for achi...

Comments from WHO for the Journal of Rehabilitation Medicine Special Supplement on ICF Core Sets.

Health indicators have traditionally focused on deaths and diseases. While mortality data or diagnostic data on morbidity are important in their own right, they do not adequately capture health outcomes of individuals or populations. Diagnosis alone does not explain what patients can do, what they need, what their prognosis will be and what the cost of treatment will be. To deal with such quest...

Let n0 be a scalar used to denote the “prior” sample size for each of the latent classes. In our empirical work, we took the value of n0 to be 1. Let ms be used to denote the number of users that fall into latent class s in any particular iteration. Then the conditional posterior for πuser is the Dirichlet density with class sample sizes given by ns = ms + n0. The conditional posterior density ...
