The Challenges of Place, Capacity, and Systems Change: The Story of Yes we can!
· Yes we can!, a comprehensive community initiative (CCI) funded by the W. K. Kellogg Foundation, was designed to improve educational and economic outcomes within the foundation’s hometown of Battle Creek, Mich. Since 2002, Yes we can! has supported five core strategies designed to trigger the systems changes needed to reduce educational and economic inequities in Battle Creek.
· Yes we can! has achieved some important wins to date; for example, more residents are involved, more neighborhoods have stronger neighborhood associations, and more organizations are engaging residents in their decision-making processes. However, the scale of wins remains small, and the targeted systemic changes have not yet emerged.
· Some common CCI design elements featured in Yes we can! may have inadvertently bounded its success: a) community building efforts targeted small-scale places, restricting the scale and scope of wins; b) demands for current work competed with building capacities for future work; and c) local partners who were implementing their individual grants struggled to maintain a focus on the larger vision and collective work
Adaptive Monotone Shrinkage for Regression
We develop an adaptive monotone shrinkage estimator for regression models
with the following characteristics: i) dense coefficients with small but
important effects; ii) a priori ordering that indicates the probable predictive
importance of the features. We capture both properties with an empirical Bayes
estimator that shrinks coefficients monotonically with respect to their
anticipated importance. This estimator can be rapidly computed using a version
of Pool-Adjacent-Violators algorithm. We show that the proposed monotone
shrinkage approach is competitive with the class of all Bayesian estimators
that share the prior information. We further observe that the estimator also
minimizes Stein's unbiased risk estimate. Along with our key result that the
estimator mimics the oracle Bayes rule under an order assumption, we also prove
that the estimator is robust. Even without the order assumption, our estimator
mimics the best performance of a large family of estimators that includes the
least squares estimator, constant- ridge estimator, James-Stein
estimator, etc. All the theoretical results are non-asymptotic. Simulation
results and data analysis from a model for text processing are provided to
support the theory.Comment: Appearing in Uncertainty in Artificial Intelligence (UAI) 201
Auxin-induced growth inhibition a natural consequence of two-point attachment
It is characteristic of a great number of biologically active substances that the responses which they elicit are twofold, low concentrations of the material promoting a particular activity, and higher concentrations inhibiting it. This is the case with the auxin-induced growth responses of plants. An active auxin such as indole acetic acid (IAA) brings about and is essential to growth in length of stems, hypocotyls and other plant organs including the Avena coleoptile

The Heroic in Middle-earth
Gives examples of several types of heroism: the survival-hero, whose heroism is a reaction to a hostile environment; the destiny-hero, who has been chosen to fulfill a task beyond his normal capabilities; the honor-hero, motivated by a desire for reputation and fame; and the ethic-hero, whose self-respect demands he act when circumstances arise that require it. Describes the moral framework of Middle-earth as one that constantly presents opportunities for heroic action, which in turn influences and supports later heroic actions through providing examples to emulate, clues to effective action, or heirloom objects that assist later heroes. In this framework, all heroic actions against evil are valuable and have consequences
Sindarin and Quenya Phonology
