The question of the subject of sentiments in Descartes' dualism

2014

The goal of this thesis is to address the question of what would be the subject of the predicates that denote sentiments in Descartes’ writings. The proposed hypothesis is that substances can only be regarded as « the ultimate subjects of inherence » of these predicates. Nevertheless, it will be argued that men and animals, although they are not substances, may be considered the « subjects of attribution » of such predicates, since they have a specific unit, namely, a « unity of composition », which ensures that attribution. Therefore, the thesis will be developed in three main axes. From an examination of the Cartesian theory of substance and its definitions, we analyze the concept of exte…

L'orientation professionnelle des diplômés des Beaux-Arts : étude des stratégies de positionnement

2006

The artistic labour market has specific features (flexibility, self-employment, precariousness, multi-activity...) that make it an interesting field to study. Graduates of the Fine Art schools are presented on this market with a diploma of Bac+5 level. They are however far from constituting a homogeneous population. This study shows how differentiated positioning choices are linked with curriculum and personal characteristics of the graduates. Thus, whereas the artistic careers remain given, in the imaginary collective, by the idea of vocation, this article tries to prolong the analyses on individual strategies on the entering on the labour market by showing that the Graduate of the Fine Ar…

Le collégien en difficulté : un constat local et des propositions d'aide individualisée

2003

For some years now, the management of pupil diversity has been the subject of considerable debate, both at the level of the education system and within separate establishments. The principal questions concern the actions to be implemented to allow all pupils to acquire a common base of knowledge and skills during the four years of lower secondary education. Numerous systems have been developed in recent years: remedial teaching, differentiated pedagogy, individual support, reorganisation of timetables, the grouping of pupils, diversified careers, etc., but tangible results have not always been observed. A worrying percentage of pupils still enter lower secondary education with serious learn…

Phase-Noise and Amplitude-Noise Measurement of DACs and DDSs

2019

This article proposes a method for the measurement of Phase Noise (PN, or PM noise) and Amplitude Noise (AN, or AM noise) of Digital-to-Analog Converters (DAC) and Direct Digital Synthesizers (DDS) based on modulation-index amplification. The carrier is first reduced by a controlled amount (30-40 dB) by adding a reference signal of nearly equal amplitude and opposite in phase. Then, residual carrier and noise sidebands are amplified and sent to a conventional PN analyzer. The main virtues of our method are: (i) the noise specs of the PN analyzer are relaxed by a factor equal to the carrier suppression ratio; and, (ii) the capability to measure the AN using a PN analyzer, with no need for th…

Assessment of Researchers Through Bibliometric Indicators: The Area of Information and Library Science in Spain as a Case Study (2001–2015)

2018

Research activities are subject to constant processes of evaluation, which increasingly include the use of bibliometric indicators to support decision-making. This paper presents a model for the individual evaluation of different facets of researchers' work and discusses the interest in using “control” parameters to identify deviations suggesting inappropriate conduct. The proposed model is illustrated through an empirical example that analyzes the activity of Spanish researchers in the area of Library and Information Science. There are important differences among the most productive authors, and in many cases, there is no association between the degree of participation in high-impact journ…

Study of the accretion torque during the 2014 outburst of the X-ray pulsar GRO J1744−28

2017

We present the spectral and timing analysis of the X-ray pulsar GRO J1744-28 during its 2014 outburst using data collected with the X-ray satellites Swift, INTEGRAL, Chandra, and XMM-Newton. We derived, by phase-connected timing analysis of the observed pulses, an updated set of the source ephemeris. We were also able to investigate the spin-up of the X-ray pulsar as a consequence of the accretion torque during the outburst. Relating the spin-up rate and the mass accretion rate as $\dot{\nu}\propto\dot{M}^{\beta}$, we fitted the pulse phase delays obtaining a value of $\beta=0.96(3)$. Combining the results from the source spin-up frequency derivative and the flux estimation, we constrained …

ESE. Estudios sobre educación

2007

Resumen tomado del autor Título, resumen y palabras clave también en inglés El conocimiento de la caracteriología permite al educador utilizar las tendencias naturales de los jóvenes para orientar su crecimiento como personas, ampliar los márgenes de su educabilidad, y servir de base a la personalización de la enseñanza, porque permite diversificar las intervenciones educativas en función de las características de los alumnos. Seguidamente, se proponen nuevamente las aportaciones de la caracteriología de Heymans y Le Senne desde una óptica educativo-metodológica. Se analizan los distintos significados de los términos 'temperamento', 'carácter' y 'personalidad'; se presentan los principios f…

VLBA polarimetric monitoring of 3C 111

2018

Context. While studies of large samples of jets of active galactic nuclei (AGN) are important in order to establish a global picture, dedicated single-source studies are an invaluable tool for probing crucial processes within jets on parsec scales. These processes involve in particular the formation and geometry of the jet magnetic field as well as the flow itself. Aims. We aim to better understand the dynamics within relativistic magneto-hydrodynamical flows in the extreme environment and close vicinity of supermassive black holes. Methods. We analyze the peculiar radio galaxy 3C 111, for which long-Term polarimetric observations are available. We make use of the high spatial resolution of…

A novel homologous model for noninvasive monitoring of endometriosis progression.

2017

To date, several groups have generated homologous models of endometriosis through the implantation of endometrial tissue fluorescently labeled by green fluorescent protein (GFP) or tissue from luciferase-expressing transgenic mice into recipient animals, enabling noninvasive monitoring of lesion signal. These models present an advantage over endpoint models, but some limitations persist; use of transgenic mice is laborious and expensive, and GFP presents poor tissue penetration due to the relatively short emission wavelength. For this reason, a homologous mouse model of endometriosis that allows in vivo monitoring of generated lesions over time and mimics human lesions in recipient mice wou…
