La domesticación de la naturaleza: de la artificialización a la intervención
2010
Darwin tuvo muy presente el paralelismo entre la selección artificial de las especies domesticadas y la selección natural. De hecho, la domesticación de plantas y animales no ha sido otra cosa que el arte de dirigir entes naturales en direcciones determinadas. Pero: ¿hasta dónde hemos llevado este proceso de domesticación? No se trata ya solamente de domesticar otras especies, hemos domesticado muchas otras cosas, desde eso otro que denominamos ambiente hasta nosotros mismos. La ciencia juega un papel creciente en el proceso de domesticación, transitando con racionalización creciente desde una domesticación sin mucho fundamento científico (artificialización) a otra plenamente teorizada (en …
Gadamer sobre el concepto aristotélico de phrónesis
2005
Por más que en Aristóteles no se trate del problema hermenéutico, ni mucho menos de su dimensión histórica, si comparamos el análisis que Aristóteles hace del fenómeno ético (y en particular de la phrónesis) con lo que es el planteamiento de Verdad y método, resulta que, efectivamente, como quiere Gadamer, el análisis que Aristóteles hace de la virtud dianoética de la phrónesis sería una especie de modelo de las cuestiones que en Verdad y método Gadamer plantea como tarea de una hermenéutica filosófica. Esta apelación a la noción aristotélica de phrónesis se convierte además en Verdad método en una crítica de las estructuras formales de la conciencia moderna o en una crítica de la autocompr…
Diagnostic validity of ICDAS II, VistaProof and a combination of these two methods. An in vitro study in pre-cavitated lesions
2017
Purpose In view of the present fall in advanced cavitation lesion prevalence, diagnostic methods have been developed to assist in assessing and measuring pre-cavitation lesions. The purpose of this study was to assess the VistaProof fluorescence-based system in vitro and compare the results with those of visual examination using the ICDAS II criteria. Methods 100 permanent teeth were collected and 65 were chosen at random for this study. Two separate examiners each examined them twice, 3 weeks apart, assessing them in accordance with ICDAS II. They were subsequently examined with the VistaProof system and the images were stored in the computer program. After obtaining all these data, the te…
A composite indicator index as a proxy for measuring the quality of water supply as perceived by users for urban water services
2021
Abstract The objective of this study is to develop a composite indicator (CI) to measure the quality of water supply based on the variables that are considered to affect users’ perceptions of water supply quality. The proposed CI includes six relevant aspects that determine users’ perceptions of water supply quality (network quality, water quality, water price, complaints, inconvenience caused by upgrading the network, and continuity of service) in a simple, economical, and objective way, using multi-criteria decision analysis (MCDA) with weights based on data envelopment analysis (DEA). The CI was applied to 32 municipalities in the metropolitan area of Valencia (Spain). The results show t…
Diversità di genere e sistema sanitario: un’analisi su un campione di aziende sanitarie italiane
2022
Il lavoro analizza in che misura la diversità di genere fa parte delle attuali pratiche delle aziende sanitarie. Attraverso un’analisi di tipo statistico-inferenziale su un campione di 39 strutture ospedaliere appartenenti al Gruppo San Donato, ha lo scopo di valutare se la presenza delle donne nel CdA influenza la performance aziendale. I risultati suggeriscono che la diversità nelle aziende sanitarie è un tema poco esplorato e non mancano opportunità e ostacoli al percorso di carriera delle donne. L’analisi di correlazione e regressione conferma che la presenza delle donne è positivamente correlata all’indice di performance delle strutture; la strada per arrivare alla parità non è breve e…

Tryptophan promotes morphological and physiological differentiation in Streptomyces coelicolor.
2015
The molecular mechanisms regulating tryptophan biosynthesis in actinomycetes are poorly understood; similarly, the possible roles of tryptophan in the differentiation program of microorganism life-cycle are still underexplored. To unveil the possible regulatory effect of this amino acid on gene expression, an integrated study based on quantitative teverse transcription-PCR (qRT-PCR) and proteomic approaches was performed on the actinomycete model Streptomyces coelicolor. Comparative analyses on the microorganism growth in a minimal medium with or without tryptophan supplementation showed that biosynthetic trp gene expression in S. coelicolor is not subjected to a negative regulation by the …

Assessing uncertainty of voter transitions estimated from aggregated data. Application to the 2017 French presidential election
2020
[EN] Inferring electoral individual behaviour from aggregated data is a very active research area, with ramifications in sociology and political science. A new approach based on linear programming is proposed to estimate voter transitions among parties (or candidates) between two elections. Compared to other linear and quadratic programming models previously published, our approach presents two important innovations. Firstly, it explicitly deals with new entries and exits in the election census without assuming unrealistic hypotheses, enabling a reasonable estimation of vote behaviour of young electors voting for the first time. Secondly, by exploiting the information contained in the model…
Boosting working memory with accelerated clocks
2021
Our perception of time varies with the degree of cognitive engagement in tasks. The perceived passage of time accelerates while working on demanding tasks, whereas time appears to drag during boring situations. Our experiment aimed at investigating whether this relationship is mutual: Can manipulated announcements of elapsed time systematically affect the attentional resources applied to a cognitive task? We measured behavioral performance and the EEG in a whole report working memory paradigm with six items of different colors that each had to be reported after a short delay period. The 32 participants were informed about the current time after each 20 trials, while the clock was running at…
