Building Deeper Relationships: How Steppenwolf Theatre Company Is Turning Single-Ticket Buyers Into Repeat Visitors
Describes the company's strategies to engage all audience members, including through post-show discussions, special events, diverse online content, and equal treatment of subscribers and non-subscribers; outcomes; and contributing factors
The Healthy Farms, Food and Communities Act: Policy Initiatives for the 2002 Farm Bill And the First Decade of the 21st Century
This policy document includes a legislative initiative to be incorporated into the 2002 Farm Bill, and a broader set of policy principles and legislation endorsed by CFSC. Both policy platforms create the basis for furthering the goals of healthy farms, healthy food, and, ultimately, healthy communities

Shock-induced temperatures of MgO
Shock-compressed MgO radiates thermally at temperatures between 2900 and 3700 K in the 170–200 GPa pressure range. A simple energy-transport model of the shocked-MgO-targets distinguishes between different shock-induced radiation sources in these targets and provides estimates of spectral absorption-coefficients, α_(λMgO), for shocked MgO (e.g. at 203 GPa, α_(λMgO) ~ 630, 7500, 4200 and 3800 m^(−1), at 450, 600, 750 and 900 nm, respectively). The experimentally inferred temperatures of the shock-compressed states of MgO are consistent with temperatures calculated for MgO assuming that (1) it deforms as an elastic fluid, (2) has a Dulong-Petit value for specific heat at constant volume in its shocked state, and (3) undergoes no phase transformation below 200 GPa
Dynamic compression of diopside and salite to 200 GPa
New Hugoniot data on single crystal diopside, CaMgSi_2O_6 (Di), suggest that transformation to a high-pressure thermomechanical state begins at ∼50 GPa and is complete above 100 GPa, in agreement with other pyroxenes and silicates of geophysical interest. Comparison of the new high pressure phase (HPP) data for Di and salite, CaMg_(0.82)Fe_(0.18)Si_2O_6 (Sa) with appropriate mixed oxide and perovskite models implies compatibility between either model and the data. Conversely, least-squares fits to the HPP Di data favor lower (3.6 - 3.9 Mg/m³) values of zero-pressure, room-temperature density than the models (4.0 - 4.1 Mg/m³). Similar comments apply to porosity-corrected HPP hedenbergite (Hd) data. The HPP Di, Sa, and Hd data also imply much larger density differences between these compositions in the HPP regime (e.g., ≈0.8 Mg/m³ between Di and Hd) than at STP (0.38 Mg/m³). This may represent the influence of multiple transition processes (e.g., polymorphism and Fe^(2+) high-low spin) as a function of Fe content across the Di-Hd series. The new HPP Sa data closely parallel (≈0.1 Mg/m³ less dense) the lower mantle density profile from ∼90 GPa to 136 GPa. Our results are consistent with the speculations of Jeanloz and Ahrens on the possibility of significant Ca in the lower mantle
