Cells detect extracellular signals by allostery and then give those signals meaning by 'regulated localization'. We suggest that this formulation applies to many biological processes and is particularly well illustrated by the mechanisms of gene regulation. Analysis of these mechanisms reveals that regulated localization requires simple molecular interactions that are readily used combinatorial...

Cluster analysis is one of the most popular data analysis tools in a wide range of applied disciplines. We propose and justify a computationally efficient and straightforward-to-implement way of imposing the available information from networks/graphs (a priori available in many application areas) on a broad family of clustering methods. The introduced approach is illustrated on the problem of a...

Male executives undertake more acquisitions and issue debt more often than female executives. Further, acquisitions made by firms with male executives have announcement returns approximately 2% lower than those made by female executive firms, and debt issues also have lower announcem...

How do senior business executives rank their preferences for various ethical principles? And how strongly do the executives believe in these principles? Also, how do these preference rankings relate to the way the executives see the future (wherein business decisions play out)? Research on these questions may provide us with an appreciation of the complexities of ethical behavior in management ...
