Sociodemographic and environmental correlates of active commuting in rural America.
PURPOSE This research investigated participation rates in 3 modes of active commuting (AC) and their sociodemographic and physical environmental correlates in rural America. METHODS The 2000 Census supplemented with other data sets were used to analyze AC rates in percentage of workers walking, biking, and taking public transportation to work in 14,209 nonmetropolitan rural tracts identified ...
متن کاملOn Commuting and Non-Commuting Complexes
In this paper we study various simplicial complexes associated to the commutative structure of a finite group G. We define NC(G) (resp. C(G)) as the complex associated to the poset of pairwise non-commuting (resp. commuting) sets of nontrivial elements in G. We observe that NC(G) has only one positive dimensional connected component, which we call BNC(G), and we prove that BNC(G) is simply conn...
متن کاملSpin in the path integral : anti - commuting versus commuting variables
We discuss the equivalence between the path integral representations of spin dynamics for anti-commuting (Grassmann) and commuting variables and establish a bosonization dictionary for both generators of spin and single fermion operators. The content of this construction in terms of the representations of the spin algebra is discussed in the path integral setting. Finally it is shown how a 'fre...
متن کاملEla Commuting
The variety C(3, n) of commuting triples of n × n matrices over C is shown to be irreducible for n = 7. It had been proved that C(3, n) is reducible for n ≥ 30, but irreducible for n ≤ 6. Guralnick and Omladič have conjectured that it is reducible for n > 7.
متن کاملPublic Diplomacy and its Institutions in United States of America
Although, once, in the far past, sending gifts and missionaries was called a type of public diplomacy, today it is manifested as academic disciplines, policy making institutions, and multi-purpose organizations. The most important institutions of these kinds, now, exist in the US, whose purpose is to promote the politics of this country as Public Diplomacy and to follow local and international ...
