An integrated study including magnetostratigraphy, larger benthic foraminifera and calcareous nannofossil biostratigraphy is presented herein. This work was performed in shallow marine siliciclastics rich foraminifera, around the Ypresian/Lutetian boundary Ésera valley (South-Central Pyrenees). Although content studied interval low, not allowing a precise Y/L to be recognised, taxa found are en...

Cortisol, 11-deoxycorticosterone, progesterone, 17 alpha-hydroxy-progesterone, 17 alpha-hydroxy-20 beta-dihydroprogesterone, or a combination of the last 2 steroids, were injected into different groups of immature female Epinephelus. None of the steroids tested had significant effects on serum electrolyte level, and hepatosomatic and gonadosomatic indices. Serum glucose concentration was elevat...

This paper addresses the choice of an optimal smoothing parameter for local polynomial matching. A version of Empirical Bias Bandwidth Selection (EBBS) proposed by Ruppert (1997) is applied to account for the MSE computation of the matching estimator. Thereby, an estimator for the large sample variance of the local polynomial matching estimator is also provided. A Monte Carlo study indicates be...

We suggest a non-parametric heteroscedasticity and autocorrelation consistent (HAC) estimator of the variance–covariance (VC) matrix for a vector of sample moments within a spatial context. We demonstrate consistency under a set of assumptions that should be satisfied by a wide class of spatial models. We allow for more than one measure of distance, each of which may be measured with error. Mon...

Since it was shown by Wilkins et al. (1950) that high output of urinary 17-ketosteroids in cases of congenital virilizing adrenal hyperplasia was suppressed by administration of glucocorticoids, the syndrome has been considered to be due to a deficiency in the enzymatic processes necessary for biosynthesis of cortisol. The most common type of the cases shows disturbances in changing 17ƒ¿hydroxy...

The paper analyzes how social barriers to communication affect economy-wide productivity and factor accumulation. Using a dynamic model of an economy that includes a reproducible capital stock (physical or human) and effective labor, a negative relationship is shown to exist between social barriers to communication and total factor productivity (TFP), per capita consumption and reproducible cap...

The effect of norrisolide (4) and designed analogues on the Golgi membranes is presented. We found that 4 is the first compound known to induce an irreversible vesiculation of these membranes. To investigate the chemical origins of this new effect we synthesized and evaluated a series of norrisolide analogues in which the chemical functionalities present in the parent structure were altered. Su...

Despite mounting evidence on the potential benefits of inbound open innovation, little is known about how firms purposefully manage inflows of knowledge. We investigate the use of two knowledge governance procedures—project management and knowledge matching—in collaborative inbound open innovation. Our findings suggest that, in addition to “knowledge-precursors,” which the literature on open in...

We model unobserved preference heterogeneity in demand systems as random Barten scales in utility functions. These Barten scales appear as random coefficients multiplying prices in demand functions. Consumer demands are nonlinear in prices and may have unknown functional structure. We therefore prove identification of additive Generalized Random Coefficients models, defined as additive nonparam...

Using and extending fractional order statistic theory, we characterize the O(n−1) coverage probability error of the previously proposed confidence intervals for population quantiles using L-statistics as endpoints in Hutson (1999). We derive an analytic expression for the n−1 term, which may be used to calibrate the nominal coverage level to get O(n−3/2 log(n)) coverage error. Asymptotic power ...
