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

Ejaculate Investment in a Promiscuous Rodent, \u3cem\u3ePeromyscus maniculatus\u3c/em\u3e: Effects of Population Density and Social Role

Questions: How does average male investment in ejaculates vary with changing population density (and thus with the risk of sperm competition) in a promiscuous species? Do individual male investment strategies vary with population density? Data studied: Total testicular mass, somatic mass and annual population density for wild-caught male deer mice, Peromyscus maniculatus, collected by snap-trapping over a 23-year period in Algonquin Provincial Park, Ontario, Canada. Search methods: We analysed the relation between mean testicular mass and mouse population densities across years. To investigate individual investment patterns, we compared the relation between total testicular mass and somatic mass among males for years differing in population density. Conclusions: Average investment in the testes was positively correlated with annual population density. An individual’s investment in testes depended on both the abundance of rival males and on relative body size, a trait associated with social rank
