Aggressive vs. discrete marketing

Aggressive vs nonaggressive therapy for metastatic NSCLC.

Clinicians tend to underestimate potential modest benefits of chemotherapy. They are often reluctant to refer patients for chemotherapy, perhaps because they expect the side effects to outweigh any perceived benefits. However, patients are much more ready to accept chemotherapy, even when the likely benefits are small. Quality of life, change in performance status, and relief of tumor-related s...

Probability Distributions: Discrete vs. Continuous

Discrete Stochastic Submodular Maximization: Adaptive vs. Non-adaptive vs. Offline

We consider the problem of stochastic monotone submodular function maximization, subject to constraints. We give results on adaptivity gaps, and on the gap between the optimal offline and online solutions. We present a procedure that transforms a decision tree (adaptive algorithm) into a non-adaptive chain. We prove that this chain achieves at least τ times the utility of the decision tree, ove...

DSS Effectiveness in Marketing Resource Allocation Decisions: Reality vs. Perception

W study the process by which model-based decision support systems (DSSs) influence managerial decision making in the context of marketing budgeting and resource allocation. We focus on identifying whether and how DSSs influence the decision process (e.g., cognitive effort deployed, discussion quality, and decision alternatives considered) and, as a result, how these DSSs influence decision outc...
