Rational Hermite Interpolation and Quadrature

1993

Rational Hermite interpolation is used in two different ways in order to derive and analyze quadrature rules. One approach yields quadratures of Gaussian-type whereas the other one generalizes Engels’ dual quadratures exhibiting the close connection between rational Hermite interpolation and quadrature in general.

High Wage Workers Match with High Wage Firms: Clear Evidence of the Effects of Limited Mobility Bias

2012

Positive assortative matching implies that high productivity workers and firms match together. However, there is almost no evidence of a positive correlation between the worker and firm contributions in two-way fixed-effects wage equations. This could be the result of a bias caused by standard estimation error. Using German social security records we show that the effect of this bias is substantial in samples with limited inter-firm movement. The correlation between worker and firm contributions to wage equations is unambiguously positive.

Microwave flash-synthesis of iron oxides nanoparticles

1999

Hematite particles have been synthesized by a one step thermohydrolysis of nitrate iron (III) solutions. The microwave system (RAMO system) designed by the authors is able to induce very fast heating rates within an autoclave. These operating conditions induce precipitation reactions in the entire volume of the reactor. These precipitation conditions lead to instantaneous nucleation of monodisperse particles (separation of the nucleation and growth events). These results indicate that it should be possible to produce very well-crystallized hematite particles which can be used as precursors for production of magnetite or maghemite.

Los contratos en materia de reproducción humana asistida: especial tratamiento de la autonomía de la voluntad en las donaciones de gametos y en el de…

2022

RESUMEN: A pesar de que en nuestro país la autonomía privada preside la regulación principal en materia de contratos, ésta se encuentra ampliamente condicionada a la hora de suscribir acuerdos en materia de reproducción humana asistida. En consecuencia, es la Ley 14/2006, de 26 de mayo, la que establece ineludiblemente las pautas y requisitos que deben cumplir las partes intervinientes. De esta forma, las donaciones de gametos llevadas a cabo en nuestro país, o la toma de decisión sobre el destino que habrá de darse a los embriones crioconservados, están absolutamente marcados por la ley, dejando un escaso margen de actuación a las clínicas y usuarias que participan en estas prácticas. Por …

Power of Paradox: Grassroots Organizations’ Legitimacy Strategies Over Time

2021

Fringe stakeholders with limited resources, such as grassroots organizations (GROs), are often ignored in business and society literature. We develop a conceptual framework and a set of propositions detailing how GROs strategically gain legitimacy and influence over time. We argue that GROs encounter specific paradoxes over the emergence, development, and resolution of an issue, and they address these paradoxes using cognitive, moral, and pragmatic legitimacy strategies. While cognitive and moral strategies tend to be used consistently, the flexible and paradoxical use of pragmatic strategies has important consequences, both for GROs’ legitimacy and for their potential influence over powerf…

Roman quarries of the Iberian Peninsula: "Anasol" and "Anasol-type".

2007

The Iberian peninsula is rich in marble, both white and coloured, of excellent quality, used in the past (Pliny NH, XXXVI, II) and also at the present time as material for building and decoration. Many types of these marbles are similar to some, better known, Greek, Italian, Egyptian and Asian marbles. During the Roman Empire “ marmor carystium ” was extensively used. Taking into account the great similarity of this marble with the “ anasol ” and “ anasol ”-types mined in Spain and Portugal, this work presents a minero-petrographic, chemical and geochemical characterisation of these lithotypes, aiming at finding parameters to distinguish them from the better-known Greek and Italian “ cipoll…

Factor Structure and Construct Validity of the Youth Psychopathic Traits Inventory and Its Shorten Version in Chinese Detained Boys

2019

The Youth Psychopathic Traits Inventory (YPI) was designed to assess psychopathic traits in adolescents. However, there exists limited evidence for the factor structure and psychometric properties of the YPI when used with Chinese detained juveniles. The present study aimed to examine the factor structure and construct validity of the YPI and its shortened version (YPI-S) in a sample of 607 Chinese 14- to 22-year-old detained boys (M = 17.15, SD = 1.09). Confirmatory factor analyses revealed a bifactor model which best fit the data at the subscale level for the YPI, and at the item level for the YPI-S. The internal consistency of the YPI and YPI-S scores ranged from marginal to good. Both t…
