The vulcanization transition is addressed via a minimal replica-field-theoretic model. The appropriate long-wavelength behavior of the two- and three-point vertex functions is considered diagrammatically, to all orders in perturbation theory, and identified with the corresponding quantities in the Houghton-Reeve-Wallace field-theoretic approach to the percolation critical phenomenon. Hence, it ...

Tate sequences are an important tool for tackling problems related to the (ill-understood) Galois structure of groups of S-units. The relatively recent Tate sequence “for small S” of Ritter and Weiss allows one to use the sequence without assuming the vanishing of the S-class-group, a significant advance in the theory. Associated to Ritter and Weiss’s version of the sequence are connecting homo...

Collegiate recreation and intercollegiate athletics have an impact on individual, group, and community development of students who are participants, employees, and athletes and learn leadership within these environments. This chapter explores and applies leadership frameworks in recreation and athletics.

The practice of learning from multiple instances seems to allow children to learn about relational structure. The experiments reported here focused on two issues regarding relational learning from multiple instances: (a) what kind of perceptual situations foster such learning and (b) how particular object properties, such as complexity and similarity, interact with relational learning. Two kind...

Over the last few years we have seen a rapid growth in the Web of Data where now statistics indicate that there are around 100 billion semantic statements available on the Web. Governments, especially the US and UK Governments, are producing hundreds of thousands of public datasets in machine readable form on the Web using Web standards such as RDF(S) and SPARQL. Major Web and Media players suc...

We survey the literature on social insurance, focusing on recent work that has connected theory to evidence to make quantitative statements about welfare and optimal policy. Our review contains two parts. We …rst discuss motives for government intervention in private insurance markets, focusing primarily on selection. We review the original theoretical arguments for government intervention in t...

The appearance of infinitely-many period-doubling cascades is one of the most prominent features observed in the study of maps depending on a parameter. They are associated with chaotic behavior, since bifurcation diagrams of a map with a parameter often reveal a complicated intermingling of period-doubling cascades and chaos. Period doubling can be studied at three levels of complexity. The fi...

The visual system is beautifully crafted to transmit information of the external world to visual processing and cognitive centers in the brain. For visual information to be relayed to the brain, a series of axon pathfinding events must take place to ensure that the axons of retinal ganglion cells, the only neuronal cell type in the retina that sends axons out of the retina, find their way out o...

BACKGROUND Inappropriate emergency department (ED) use among Medicaid enrollees is considered a problem because of cost. We developed and evaluated a system change innovation designed to remove system barriers to primary care access for Medicaid patients. METHODS Patients who presented to the ED without an identified primary care provider were randomized to the intervention (n = 72) or compar...
