Why do Banks Fail ?

Banks advance loans in the absence of precise knowledge in relation to the outcome of borrowers’ projects. Consequently, uncertainty in relation to loan repayment emerges. Thus, banks introduce the ‘credit standard’ as insurance against loans, so that should borrowers’ projects fail, borrowers have an alternative means of honouring their debt obligations.

Application of Ecological Theory to Management of Arid Drylands: An Example from China

These differentecological states are the result of interactions among climate, soils, grazing history,and management practices. The notion of a single ‘‘pristine’’ final state is onlyconceptual in nature, and because of this, dynamic thresholds and the effects...

Why do mitral valve repairs fail?

In this issue of JASE, Magne et al continue their previous work using echocardiography to analyze outcomes of mitral valve repair for ischemic mitral regurgitation, demonstrating that continued adverse left ventricular (LV) remodeling may not be a prerequisite for recurrent mitral valve regurgitation in patients who had undergone initially successful repairs. They observed a group of 26 patient...
