An efficient manual micro assembly is a critical step in micro production. For a human operator, the manual assembly of miniature products presents a particular challenge. Amongst the challenges present in manual micro assembly are inadequately large human forces which increase the risk of damaging sensible products as well as the operator‟s limited capability of executing fine precision moveme...
The analysis of high-throughput data sets, such as microarray data, often requires that individual variables (genes, for example) be grouped into small clusters such that all the variables in any given cluster have highly correlated values across all samples. Gene shaving is an established method for generating such clusters, but is overly sensitive to the input data: changing one sample out of...
Using both multivariate regressions, simultaneous nonlinear equations and a discrete time hazard model, I find that the level of CSR in a firm is a significant determinant of distress, even after controlling for previously identified drivers of firm distress. The relationship is robust to the endogeneity of CSR investments and free cash flow and suggests that there is informational value in ext...
