The informational role of thin options markets: Empirical evidence from the Spanish case
2016
This study investigates the informational role of thin options markets, specifically the Spanish options market. Firstly, we examine the effect of options markets by analysing stock market reaction to earnings news, conditional on the availability of options markets. Secondly, we examine options trading activity before the release of earnings news (including the announcement period). The results show that the impact on prices before the earnings release is significantly bigger when options trading is available. Moreover, the dissemination of earnings news is associated with significant unusual activity in the options market due to informed trading, especially when the earnings surprise is h…

L'intervento nei centri storici: l'ANCSA e il caso Erice
2014
Il Convegno “Salvaguardia e risanamento dei centri storico-artistici”, svoltosi a Gubbio nel Settembre del 1960, offre l’occasione per fare un bilancio sulla situazione dei centri storici, sull’insufficienza normativa dei piani regolatori, sulla tecnica urbanistica e confrontare contemporaneamente le esperienze concrete di alcuni piani e il relativo approccio al tema dell’intervento nei centri storici. Il comitato promotore del Convegno di Gubbio, noto per avere prodotto la celebre Dichiarazione finale poi denominata “Carta di Gubbio”, si trasformerà l’anno successivo in Comitato permanente fondando a Gubbio l’Associazione nazionale centri storico-artistici (ANCSA). Appare significativo che…

La consegna educativa
2021
Una rilettura critica del saggio “La consegna”, di Antonio Bellingreri. La riflessione, di pedagogia fondamentale e filosofia dell’educazione, è volta ad indagare i tratti costitutivi, ovvero l’essenza, della persona umana, a partire da un’analisi dell’epoca contemporanea, restituitaci dalla letteratura come tardo-moderna. Di una gioventù privata di significativi modelli di comportamento e sistemi valoriali, diffidente del passato non meno che del futuro, intende farsi carico l’educazione, privilegiato strumento per re-immettere in circolo valori e significati smarriti. Divenendo consegna, la relazione educativa risponde al bisogno posto al fondo della persona umana (il bisogno di riconosci…
Forecasting Weekly Electricity Prices at Nord Pool
2007
This paper analyses the forecasting power of weekly futures prices at Nord Pool. The forecasting power of futures prices is compared to an ARIMAX model of the spot price. The time series model contains lagged external variables such as: temperature, precipitation, reservoir levels and the basis (futures price less the spot price); and generally reflects the typical seasonal patterns in weekly spot prices. Results show that the time series model forecasts significantly beat futures prices when using the Diebold and Mariano (1995) test. Furthermore, the average forecasting error of futures prices reveals that they are significantly above the settlement spot price at the ‘delivery week’ and th…
Effect of high-fluoride dentifrice and bracket bonding composite material on enamel demineralization adjacent to orthodontic brackets in vitro
2020
Background There is a lack of information about the association of high-fluoride dentrifrice and fluoride-containing bonding material to prevent enamel white spot lesions development adjacent to brackets. The aim of this in vitro study was to evaluate the effect of high-fluoride dentifrice and fluoride-containing bonding material on enamel demineralization adjacent to orthodontic brackets. Material and methods Forty-eight enamel specimens with 7x7x2 mm were obtained from bovine incisors. Orthodontic brackets were bonded with fluoride-containing resin composite (OrthoCem®) or fluoride-free low viscosity resin. The specimens were submitted to an 8-day pH cycling that consisted in the daily im…
Combined effects of electric toothbrushing and dentifrice on artificial stain removal : an in vitro study
2018
This in vitro study aimed to clarify the combined effect of electric toothbrushing and dentifrice on the removal of artificial stain. Twenty-five bovine incisors were cut at the cervix and the crown was embedded in auto-cured acrylic resin. Specimens were abraded using #240 SiC paper to obtain a flat enamel surface, and 20 specimens were treated with 10% citric acid / 3% ferric chloride solution followed by 1% tannic acid solution to produce surface staining. They were divided into four groups: 1) brushing with an electric toothbrush and whitening dentifrice (group S+B); 2) brushing with an electric toothbrush and fluoride dentifrice (group S+C); 3) brushing with an electric toothbrush and …
Autoantibody depletion ameliorates disease in murine experimental autoimmune encephalomyelitis.
2013
Much data support a role for central nervous system antigen-specific antibodies in the pathogenesis of multiple sclerosis (MS). The effects of inducing a decrease in (auto)antibody levels on MS or experimental autoimmune encephalomyelitis (EAE) through specific blockade of FcRn, however, remain unexplored. We recently developed engineered antibodies that lower endogenous IgG levels by competing for binding to FcRn. These Abdegs ("antibodies that enhance IgG degradation") can be used to directly assess the effect of decreased antibody levels in inflammatory diseases. In the current study, we show that Abdeg delivery ameliorates disease in an EAE model that is antibody dependent. Abdegs could…
