When one conducts a census of kinds of research being published in ‘leading ’ economics journals over the last three decades one find considerable prima facie evidence that a not insignificant share of this work employs nonneoclassical types of theorizing, tools, and methods of empirical analysis, whereas in the first three postwar decades that share was far smaller. If one extends this empirical investigation to journal births in the last three decades, one finds evidence that nonneoclassical journal births significantly exceed neoclassical journal births, implying (with far fewer journal deaths over the same period) that nonneoclassical research appears to be a rising share of what is being published in economics journals as a whole. Further, conceptual evaluation of much of this recent nonneoclassical research indicates that it has origins outside of economics in other sciences, and thus it imports into economics assumptions from these other sciences about the nature of scientific explanation and about how to conceive the object of investigation in economics that depart from what underlies conventional neoclassical views (Davis, 2006b). While it is possible that this process might ultimately eliminate economics as a distinct domain of investigation in the future, the more likely possibility given
SPECTRAL ANALYSIS OF RANDOM WALK OPERATORS ON EUCLIDIAN SPACE
"... Abstract. We study the operator associated to a random walk on R d endowed with a probability measure. We give a precise description of the spectrum of the operator near 1 and use it to estimate the total variation distance between the iterated kernel and its stationary measure. Our study contains t ..."

Abstract. We study the operator associated to a random walk on R d endowed with a probability measure. We give a precise description of the spectrum of the operator near 1 and use it to estimate the total variation distance between the iterated kernel and its stationary measure. Our study contains the case of Gaussian densities on R d. hal00492441, version 1 15 Jun 2010 1.

The task of registration of free form surfaces comes up in various contexts, like object reconstruction or localization of objects. Often it should be close to ”real time”. The process is devided in two different steps: Coarse and Fine registration. Whereas the latter one is well established in form of the ICPAlgorithm, the first one is still often done by user interaction. ”Coarse ” means that an inital estimation for the transformation has to be found in order to start the ICP. A lot of strategies have been developed to perform coarse registration automatically. This contribution well overcomes some disadvantages of a prior approach that deals with objects containing planar surface parts (”technical ” objects). The complete algorithm is described in terms of graph theory and tested with data acquired by an optical range sensor. 1

The degree of approximation of infinitedimensional function classes using finite ndimensional manifolds has been the subject of a classical field of study in the area of mathematical approximation theory. In Ratsaby and Maiorov (1997), a new quantity pn(F, Lq) which measures the degree of approximation of a function class F by the best manifold H of pseudodimension less than or equal to n in the LqmeU'ic has been introduced. For sets F C E' it is defined as p,(F, l') = infm dist(FH), where dist(F,H") = sup. r inf?m, I[x.Yl]/ and H C '" is any set of VCdimension less than or equal to n where n < m. It measures the degree of approximation of the set F by the optimal set H" C of VCdimension less than or equal to n in the /[metric. In this paper we compute iMF, l" tbr F being the unit ball B' = {x ': IIxll7 < 1 } for any I < p. q < c, and for F being any subset of the boolean mcube of size larger than 2 m7, for any } <7<1 1998 hblished by Elsevier Science B.V.
