It is well known that turnover rates fall with employee tenure and employer size. We document a new empirical fact about turnover: Among surviving employers, separation rates are positively related to industry-level exit rates, even after controlling for tenure and size. Specifically, in a dataset with over 13 million matched employee-employer observations for France, we find that, all else equ...

Abntract. This paper discusses how local measurements of threedimensional positions and surface normals recorded by a set of tactile sensors may be used to identify and locate objects, from among a set of known objects. The objects are modeled as polyhedra having up to six degrees of freedom relative to the sensors. w e show that inconsistent hypotheses about pairings between sensed point...

Jones and Rachlin (2008) found that the amount of money a person is willing to forgo in order to give $75 to another person decreased as a hyperbolic function of perceived social distance, in the same way as occurs in intertemporal choice. This study aimed to extend this finding to the domain of social networks, in which social distance is defined by degrees of separation. A total of 334 partic...

In this paper we will prove that the plus cupping degrees generate a definable ideal on c.e. degrees different from other ones known so far, thus answer a question asked by A. Li and Yang.

Description The package contains functions for generating random clusters, generating random covariance/correlation matrices, calculating a separation index (data and population version) for pairs of clusters or cluster distributions, and 1-D and 2-D projection plots to visualize clusters. The package also contains a function to generate random clusters based on factorial designs with factors s...

MPSIAC is currently known as an appropriate method to measure sediment ofWatershed basins of the country while there has not been any sensitivity analysis so far forthis method. In this study, required data for MPSIAC model were gathered from six basins;Amame-Kamarkhani, Kand-Golandok, Tang Kenesht (from two different references), Nojian(from three different references), Pegahe sorkh katvand (f...

Tectonic setting exerts fi rst-order control on basin formation as refl ected in basin subsidence history. While our approach ignores the effects of fl exural loading and eustatic sea-level change, consistency of backstripped subsidence histories (i.e., with local loading effects of sediment removed) suggests consistent tectonic driving mechanisms in each tectonic setting, with the possible exc...

We present data on the efficacy of Mesocyclops longisetus as a biocontrol agent in controlling Aedes aegypti larvae in catch basins in Cali, Colombia. Additionally, we determined some of the features that facilitated the establishment of the copepods in catch basins. Between June 1999 and February 2000, 201 catch basins were treated with an average of 500 adult copepods. The copepods had establ...

[1] Large impact basins are present on many of the icy satellites of the outer solar system. Assuming that their present-day topography is uncompensated, such basins can cause significant poleward reorientations for slow-rotating satellites. This reorientation may have been accompanied by transient large-amplitude wobble. The largest basins on Tethys, Rhea and Titania are predicted to have caus...

The interior of British Columbia contains a number of fault bounded Tertiary basins that contain coal (Figure 1). This paper brings together existing data that aids in assessing the coalbed methane (CBM) potential of the basins and presents new data on some of the basins. The CBM potential of the basins ranges from up to 1 tcf at Hat Creek to a few bcf at Coal River. In all cases the resources ...
