Early-onset tobacco use and suicide-related behavior – A prospective study from adolescence to young adulthood
2018
Abstract Background Developmental relationships between tobacco use and suicide-related behaviors (SRB) remain unclear. Our objective was to investigate the longitudinal associations of tobacco use in adolescence and SRB in adulthood. Methods Using a prospective design, we examined whether tobacco use in adolescence is associated with SRB (intentional self-injury, suicide ideation) in young adulthood in a population-based sample of 1330 twins (626 males, 704 females). The baseline and follow-up data were collected by professionally administered semi-structured poly-diagnostic interviews at ages 14 and 22, respectively. Results After adjusting for multiple potential confounders, those who re…

Lautsi contra Italia: sobre la libertad religiosa y los deberes de neutralidad e imparcialidad del Estado.
2011
RESUMENRecientemente, la Gran Sala del Tribunal Europeo de Derechos Humanos ha resuelto que la presencia del crucifijo en las aulas italianas no supone una vulneración del derecho de los padres a asegurar la educación de sus hijos de conformidad con sus propias creencias religiosas y de los deberes de neutralidad e imparcialidad estatal impuestos por el derecho de libertad religiosa. Con ello revocaba una decisión en sentido contrario de una Sala de la Sección Segunda del propio tribunal. En el trabajo se repasan críticamente los fundamentos de la decisión definitiva, basada principalmente en el reconocimiento de un amplio margen de discrecionalidad en la actuación de las autoridades nacion…
Contagion of Uncertainty: Transmission of Risk from the Cryptocurrency Market to the Foreign Exchange Market
2019
Earlier research documented that cryptocurrencies, including Bitcoin, have experienced dramatic fluctuations in both market capitalization and market share in recent years. Unsurprisingly, Bitcoin returns exhibit higher volatility than traditional G-10 currencies. Our paper extends earlier research and investigates the potential impact of news originating from the Bitcoin market. Confirming earlier studies, we find that Bitcoin exhibits dramatically higher volatility than the dollar factor. Surprisingly, our findings indicate that only hacking incidents that occur in the Bitcoin market result in high levels of co-movement in the risk of both markets the cryptocurrency and the G-10 currency …
Politics, Economics and Tourism Development in Egypt: insights into the sectoral transformations of a neo-patrimonial rentier state
2008
This article challenges claims that liberalising state-regulated markets in developing countries may induce lasting economic development. An analysis of the rise of tourism in Egypt during the past three decades suggests that the effects of liberalisation and structural adjustment are constrained by the neo-patrimonial character of the Egyptian political system. Since the decline of oil-rent revenues during the 1980s tourism development has been the optimal strategy to compensate for the resulting fiscal losses. Increasing tourism revenues have helped in coping with macroeconomic imbalances and in avoiding more costly adjustment of traditional economic sectors. Additionally they provided th…
Open It And They Will Come? The Impact of Fallen Barriers on Securities Market Participation
2017
Various barriers may prevent people from entering a market. Will they participate in the market despite their inexperience once the barriers fall? I exploit the socalled German reunification experiment in order to assess the impact of removed market barriers on participation rates: While East Germans were deprived of the possibility to participate in capitalist securities markets before 1989, the reunification of Germany offered access to those markets. I estimate that a person is, ceteris paribus, by 25–30 percentage points less likely to participate over a 3–7 years horizon after being initially excluded from the securities market, suggesting a prominent role of financial experience in ex…
La libertà tra determinismo naturale e determinismo teologico: Il De servo arbitrio di Lutero
2018
L'articolo analizza il rapporto tra determinismo naturale e storico da un lato e determinismo teologico dall'altro, così come Lutero lo affronta nel De servo arbitrio, a partire dalla sua concreta esperienza di fede. L'articolo cerca di mostrare come l'idea di determinismo di Lutero sia escludente l’opposta idea d’indeterminazione, ragion per cui egli rifiuta la concezione della libertà come libertas indifferentiae, ma non la contingenza degli eventi e quindi neppure l'autodeterminazione dell'uomo. Nell'articolo si mostra come la posizione di Lutero al riguardo sia stata accolta da Leibniz e da Hegel. The article analyzes the relationship between natural and historical determinism on the on…

Hyaluronic acid and beta cyclodextrins films for the release of corneal epithelial cells and dexamethasone
2016
In this work we prepared hydrogels based on hyaluronic acid and β-cyclodextrins to sustain the release of both corneal epithelial cells and dexamethasone. This steroid is administered as eye drops several times per day to reduce the risk of rejection in the post operative period after the cornea transplantation and cell release techniques. Hydrogels were produced by crosslinking an amino derivative of hyaluronic acid, with the divinyl sulfone derivative of β-cyclodextrins, this last employed as a crosslinker and solubilizing agent. Drug release studies revealed that dexamethasone containing samples are able to extend the release of this drug for at least five days. Biological studies, condu…
Hyaluronic Acid-Based Micelles as Ocular Platform to Modulate the Loading, Release, and Corneal Permeation of Corticosteroids
2017
The aim of this work is to prepare hyaluronic acid-based micelles as a platform to load corticosteroid drugs and to improve their corneal permeation after administration on the ocular surface. Three amphiphilic derivatives of hyaluronic acid (HA) are synthesized using different amounts of hexadecylamine (C16 -NH2 ). HAC16 a, HAC16 b, and HAC16 c derivatives are able to form micelles by the cosolvent evaporation method and to entrap corticosteroids (dexamethasone, triamcinolone, triamcinolone acetonide). HAC16 a and HAC16 b micelles show the best results in terms of drug loading and particle size. They are also able to improve drug release compared to free drug solution or suspension. In add…
