“Development” and “Good Living”: Alternative Transition

Evaluating alternative MPS development methods using MCDM and numerical simulation

One of the key elements in production planning hierarchy is master production scheduling. The aim of this study is to evaluate and compare thirteen alternative MPS development methods, including multi-objective optimization as well as twelve heuristics, in different operating conditions for multi-product single-level capacity-constrained production systems. We extract six critical criteria from...

Are alternative funding plans a good idea?

M Godwin and colleagues are to be congratulated for their survey of the effect of an alternative funding plan on physician referrals; however, we have several concerns. First, the authors state that to interpret the “negative perceptions” of the respondents regarding the alternative funding plan one should “consider the confounding effect of other changes in the health care system in Ontario.” ...

Development of the renal glomerulus: good neighbors and good fences.

The glomerulus of the mammalian kidney is an intricate structure that contains an unusual filtration barrier that retains higher molecular weight proteins and blood cells in the circulation. Recent studies have changed our conception of the glomerulus from a relatively static structure to a dynamic one, whose integrity depends on signaling between the three major cell lineages: podocytes, endot...
