The present paper is the product of collaboration between a neuroscientist, an ethicist, and a contemplative exploring issues around leadership, morality, and ethics. It is an exploration on how people in roles of responsibility can better understand how to engage in discernment processes with more awareness and a deeper sense of responsibility for others and themselves. It draws upon recent research and scholarship in neuroscience, contemplative science, and applied ethics to develop a practical understanding of how moral decision-making works and is essential in this time when there can seem to be an increasing moral vacuum in leadership.

Our group has studied the spatiotemporal variation of soil and water salinity in an artificial salt marsh along the Arakawa River estuary and developed a practical model for predicting soil salinity. The salinity of the salt marsh and the water level of a nearby channel were measured once a month for 13 consecutive months. The vertical profile of the soil salinity in the salt marsh was measured once monthly over the same period. A numerical flow simulation adopting the shallow water model faithfully reproduced the salinity variation in the salt marsh. Further, we developed a soil salinity model to estimate the soil salinity in a salt marsh in Arakawa River. The vertical distribution of the soil salinity in the salt marsh was uniform and changed at almost the same time. The hydraulic conductivity of the soil, moreover, was high. The uniform distribution of salinity and high hydraulic conductivity could be explained by the vertical and horizontal transport of salinity through channels burrowed in the soil by organisms. By combining the shallow water model and the soil salinity model, the soil salinity of the salt marsh was well reproduced. The above results suggest that a stable brackish ecotone can be created in an artificial salt marsh using our numerical model as a design tool.

Underground gas storage inventory and conditions are predicted using a practical model and a noniterative solution algorithm. Various simulation scenarios concerning underground gas storage in depleted reservoirs with variable production rate and temperature conditions demonstrate the effectiveness of this approach. It is shown that the gas storage parameters can be determined conveniently by solving the system model directly without resorting to the tedious procedures of the previous approaches.
