Homfly Polynomials of Generalized Hopf Links
Following the recent work by T.-H. Chan in [HOMFLY polynomial of some
generalized Hopf links, J. Knot Theory Ramif. 9 (2000) 865--883] on reverse
string parallels of the Hopf link we give an alternative approach to finding
the Homfly polynomials of these links, based on the Homfly skein of the
annulus. We establish that two natural skein maps have distinct eigenvalues,
answering a question raised by Chan, and use this result to calculate the
Homfly polynomial of some more general reverse string satellites of the Hopf
link.Comment: Published by Algebraic and Geometric Topology at

Belief propagation in monoidal categories
We discuss a categorical version of the celebrated belief propagation
algorithm. This provides a way to prove that some algorithms which are known or
suspected to be analogous, are actually identical when formulated generically.
It also highlights the computational point of view in monoidal categories.Comment: In Proceedings QPL 2014, arXiv:1412.810

Species Profiles: Life Histories and Environmental Requirements of Coastal Fishes and Invertebrates (Mid-Atlantic): Bay anchovy
The bay anchovy
occurs along the Atlantic and Gulf
of Mexico coasts, from Cape Cod,
Massachusetts, to Yucatan, Mexico
(Hildebrand 1963), except for the
Florida Keys where it is apparently
absent (Daly 1970). (PDF contains 22 pages
The Power of Community: How Foster Parents, Teachers, and Community Members Support Academic Achievement for Foster Youth
Foster children have been identified as one of the most high-risk groups for academic failure in schools today. However, a small number of foster youth are beating the odds by achieving academically. How are they able to overcome tremendous barriers and succeed? This phenomenological study reports the findings of former foster youth and their P-12 education experience. In-depth interviews are shared, offering a rare glimpse into the challenging lives of foster youth and revealing the supports that contributed to their success. The significance of each support entity identified by the participants must be broadly shared. The support entities are family, school, community, and self-reliance. The insights of the foster youth show how family, teachers, and community can work together to support the academic achievement of foster youth
