Rivoluzione

L'opera presenta fin dal titolo "Parole in divenire. Un vademecum per l'uomo occidentale" la sua spiccata vocazione multidisciplinare, ricondotta tuttavia in una prospettiva scientificamente omogenea: quella di presentare alcune parole - concetti chiave del sapere filosofico, storico, politico, giuridico, economico nella loro trasformazione semantico-concettuale e la loro incidenza sul presente (e futuro) della cultura 'occidentale', oggi come non mai alla ricerca di una identità rifondativa. "Parole in divenire. Un vademecum per l'uomo occidentale" si rivolge non solo alle diverse componenti del mondo accademico di differenti discipline (docenti e ricercatori desiderosi di confrontarsi con…

Water-soluble polyesters from long chain alkylesters of citric acid and poly(ethylene glycol)

2007

Abstract Long chain aliphatic alcohols have been used as model compounds to develop a preparative method for a water-soluble material, which could be a carrier for triacontanol, a highly hydrophobic plant growth regulator. New polyesters from long chain aliphatic (C = 12, 18 and 22) mono-1-alkyl citrates and poly(ethylene glycol) were synthesized and characterized by NMR spectroscopy. The polyester containing the triacontyl moiety was obtained from mono-1-triacontyl citrate, which was synthesized from the corresponding alcohol extracted from the Agave fourcroydes . The molecular weight M ¯ n of the polyesters depends on experimental conditions during synthesis such as reaction time, atmosph…

Calcium dicaesium silver thiocyanate dihydrate.

2001

The title compound, CaCs2[Ag2(SCN)6]·2H2O, forms a continuous structure where the Ag atoms form chains with S atoms in the c-axis direction. The chains are bonded together through Cs and Ca atoms. The crystal water of the structure is bonded to the Ca atoms, which lie on centers of symmetry.

1D ferrimagnetism in homometallic chains

1990

The magnetic properties of the cobalt zigzag chain Co(bpy)(NCS)2 (bpy=2,2′‐bipyridine) are discussed on the basis of an Ising‐chain model that takes into account alternating Landé factors. It is emphasized, for the first time, that a homometallic chain containing only one type of site can give rise to a 1D ferrimagneticlike behavior. Juan.J.Borras@uv.es , Eugenio.Coronado@uv.es

Radiation dose in non-dental cone beam CT applications: a systematic review.

2018

Background: Radiation-induced health risks are broadly questioned in the literature. As cone beam computed tomography (CBCT) is increasingly used in non-dental examinations, its effective dose needs to be known. This study aimed to review the published evidence on effective dose of non-dental CBCT for diagnostic use by focusing on dosimetry system used to estimate dose. Materials and methods: A systematic review of the literature was performed on 12 November 2017. All the literature up to this date was included. The PubMed and web of science databases were searched. Studies were screened for inclusion based on defined inclusion and exclusion criteria according to the preferred reporting ite…

Segmentación del turista deportivo: el caso del espectador de la Fórmula 1

2021

El trabajo pretende identificar grupos de turistas de un evento deportivo, el GP Europa de Fórmula 1, con relación a su motivación para el consumo deportivo y características básicas que definen dichos grupos para conocer los perfiles de turista de un gran evento deportivo. Para caracterizar a los sujetos se utilizó el análisis clúster con una muestra de 148 asistentes al evento, turistas nacionales e internacionales. Los resultados obtenidos muestran la existencia de cuatro grupos de sujetos bien definidos: los sociales (formado por los que obtienen fuertes connotaciones sociales asistiendo al evento, el 17,6% de la muestra), los ostentosos (son el 17,5% de la muestra, que sin una motivaci…

Conocimientos y creencias que los padres y madres tienen sobre la utilización de internet por parte de sus hijos e hijas de entre 6 y 9 años

2015

El objetivo general de este estudio es aportar información sobre los conocimientos y creencias que tienen los padres y madres sobre la utilización que sus hijos e hijas de entre 6 y 9 años hacen de Internet y su protección. Hasta ahora ha existido un vacío con respecto a estudios del uso de Internet, ya no sólo por parte de los menores de estas edades, sino también por parte de sus progenitores y lo preparados que están éstos para orientar a los menores en este aspecto de la educación y de la vida. Se parte de la idea de que ha de existir un equilibrio consistente en reducir los riesgos en la utilización de la red mientras que se maximizan los beneficios. Se confeccionó un cuestionario cont…

A Self-Funding Reward Mechanism for Tax Compliance

2015

We compare in a laboratory experiment two audit-based tax compliance mechanisms that collect fines from those found non-compliant. The mechanisms differ in the way fines are redistributed to individuals who were either not audited or audited and found to be compliant. The first, as is the case in most extant tax systems, does not discriminate between the un-audited and those found compliant. The second targets the redistribution in favor of those found compliant. We find that targeting increases compliance when paying taxes generates a social return. We do not find any increase in compliance in a control treatment where individuals audited and found compliant receive symbolic rewards. It is…

Towards More Efficient Incentives for Agri-environment Measures in Degraded and Eroded Vineyards

2015

Evaluating the economic damage caused by soil erosion is important. In addition to increasing the awareness of the problem among farmers and policy makers, evaluation of the economic damage caused by erosion can promote the implementation of more sustainable soil management practices. In the present study, we describe a new approach to evaluate incentives for the adoption of agri-environment measure (AEM) in degraded and eroded vineyards. To estimate this incentive, the replacement cost (RC) and the loss of income are calculated when the vineyard is managed with conventional tillage versus a cover crop (AEM). Our findings show that the incentive could range from the loss of income due to AE…
