Leveling the playing field through partnerships and collaboration : neighborhood revitalizations and the influence of social determinants of health and institutional logics.

A qualitative study guided by grounded theory was on a Midwest US city (population \u3e 50,000 people), three of its inner city neighborhoods, and community coalition and partnership efforts in neighborhood revitalizations. A two-phase semi-structured interview methodology assessed interviewees’ experiences in initiatives focused on improving social determinants of health in the neighborhoods. Phase I interviews (n= 11) identified the spectrum of partnerships and initiatives while Phase II interviews (n=28) captured detailed experiences of interviewees. Inter-institutional systems and institutional logics theory were applied in the post-data collection analysis. Interviewees were from public and private sectors including: built environment, economic development, residential/commercial property development, higher education, urban policy, healthcare services, social services, fitness & wellness, financial institutions, and arts & cultural advancement. This study produced evidence of inter-institutional collaboration and community challenges and solutions, policy implications, and multidimensional community health impacts. The importance of trust (personal and institutional), local policymaking, ‘local social bridges’, and the importance of institutional logic elements under the Community and State institutional order in formal and informal networks were key findings in the conclusion. Insights for future research included engaging actors from multi-sectoral partners, recognize importance of “mutual interdependences”, and themes at the intersection of public health and sociology—local bridges, impact of trust and institutional order influence on urban policies

Pair Wave Functions in Atomic Fermi Condensates

Recent experiments have observed condensation behavior in a strongly interacting system of fermionic atoms. We interpret these observations in terms of a mean-field version of resonance superfluidity theory. We find that the objects condensed are not bosonic molecules composed of bound fermion pairs, but are rather spatially correlated Cooper pairs whose coherence length is comparable to the mean spacing between atoms. We propose experiments that will help to further probe these novel pairs

Could Stannern-trend eucrites be crustal-contaminated melts?

In this paper, we show that the composition of Stannern trend eucrites can be satisfactorily explained by contamination of normal main group eucrites by a crustal partial melt

Long range scattering resonances in strong-field seeking states of polar molecules

We present first steps toward understanding the ultracold scattering properties of polar molecules in strong electric field-seeking states. We have found that the elastic cross section displays a quasi-regular set of potential resonances as a function of the electric field, which potentially offers intimate details about the inter-molecular interaction. We illustrate these resonances in a ``toy'' model composed of pure dipoles, and in more physically realistic systems. To analyze these resonances, we use a simple WKB approximation to the eigenphase, which proves both reasonably accurate and meaningful. A general treatment of the Stark effect and dipolar interactions is also presented

Observation of Heteronuclear Feshbach Resonances in a Bose-Fermi Mixture

Three magnetic-field induced heteronuclear Feshbach resonances were identified in collisions between bosonic 87Rb and fermionic 40K atoms in their absolute ground states. Strong inelastic loss from an optically trapped mixture was observed at the resonance positions of 492, 512, and 543 +/- 2 G. The magnetic-field locations of these resonances place a tight constraint on the triplet and singlet cross-species scattering lengths, yielding -281 +/- 15 Bohr and -54 +/- 12 Bohr, respectively. The width of the loss feature at 543 G is 3.7 +/- 1.5 G wide; this broad Feshbach resonance should enable experimental control of the interspecies interactions.Comment: revtex4 + 5 EPS figure
