Value of Information Sharing and Lead Time Reduction in a Supply Chain with Autocorrelated Demand
We consider the two level supply chain of Lee et al. (Manage Sci 46(5):626-643, 2000) with nonstationary demand that follows an AR(1) process. Without information sharing in the supply chain, the retailer only conveys his order.
Assessment of Aggregate Interaction Effect and Aggregate Presistence Effect in Market Share Analysis
The paper proposes an alternative conceptualization to decision variable interaction in market share analysis, by isolating the interaction free market share. The multicollinearity problem would thus be reduced. Further a method to correct for autocorrelation is proposed. Persistence which is the long term impact of current marketing action is identified.

Enfranchisement from a political perspective
This paper presents an alternative theoretical perspective on democratization. Various models of democratization have been proposed in the literature, like enfranchisement in response to threats of revolution, threats of war, and split of interests among elites. However, there seems to be instances of democratization that do not follow any of these patterns.

Joint modeling of longitudinal data and informative dropout time in the presence of multiple change points
In longitudinal studies of patients with the human immunodeficiency virus (HIV), objectives of interest often include modeling of individual-level trajectories of HIV ribonucleic acid (RNA) as a function of time. Such models can be used to predict the effects of different treatment regimens or to classify subjects into subgroups with similar trajectories.
A dimensionally consistent aggregation framework for biophysical metrics
We develop a formal representation of the economy-ecosystem interaction problem by distinguishing between stock-flow, and fund-flux spaces (Georgescu-Rogen, 1971). We then define dimensionless quantities in both the cardinal stock-flow space and the ordinal fund-flux space.
