Análisis de los antecedentes histórico-filosóficos de la "paradoja cognitiva de Duval"
2015
In a famous article published in 1993, Raymond Duval highlighted a simple fact: the student may confuse the mathematical object O he is trying to build cognitively with one of its semiotic representations R(O). Duval explained that this confusion was due to a sort of inevitable paradox: only someone who has already built O, can recognize R(O) as a representation of O and not as an object in itself. Thereafter, this thought has been extremely influential for researchers. However, even if in different terms, many scholars of semiotics have emphasized the same phenomenon. In this paper we propose to remind some of them. En un famoso artículo publicado en 1993, Raymond Duval evidenciaba el sigu…

How is social capital formed across the digital-physical servicescape?
2022
This study examines how consumers create social capital in interactions with other customers and service personnel while shopping in retail stores that consist of both physical and digital locations. We draw on servicescape literature to explore the role of social capital in determining the social realm in digital-physical servicescapes using data from focus group discussions. We demonstrate how customers utilize both the digital and physical servicescapes in a convergent manner to form the social realm of the servicescape with the other people in service encounters. The implications provide guidelines on how the integration of digital and physical channels facilitates trust, human contact,…
L'evoluzione dell'azione amministrativa nell'era della cittadinanza digitale
2019
Il processo di trasformazione digitale sta investendo i tradizionali modi di operare e organizzarsi della pubblica amministrazione. Lo scritto evidenzia sinteticamente in che termini tale fenomeno possa contribuire ad arricchire la sfera dei diritti individuali del cittadino, in particolare quelli esercitati all'interno del rapporto con i poteri pubblici. A tal fine, vengono presi in considerazione due ambiti specifici: il primo riguarda la rilettura del concetto di trasparenza amministrativa alla luce dei recenti interventi legislativi e della diffusione delle nuove tecnologie digitali; il secondo attiene al settore dei servizi pubblici e al suo ammodernamento tecnologico in virtù dei pecu…
Comparison of essential oil components and in vitro anticancer activity in wild and cultivated Salvia verbenaca.
2015
The objectives of our research were to study the chemical composition and the in vitro anticancer effect of the essential oil of Salvia verbenaca growing in natural sites in comparison with those of cultivated (Sc) plants. The oil from wild (Sw) S. verbenaca presented hexadecanoic acid (23.1%) as the main constituent, while the oil from Sc plants contained high quantities of hexahydrofarnesyl acetone (9.7%), scarce in the natural oil (0.7%). The growth-inhibitory and proapoptotic effects of the essential oils from Sw and Sc S. verbenaca were evaluated in the human melanoma cell line M14, testing cell vitality, cell membrane integrity, genomic DNA fragmentation and caspase-3 activity. Both t…
Regulating (and Self-regulating) the Sharing Economy in Europe: An Overview
2018
The article describes the main legal challenges for regulating the sharing (or collaborative) economy in Europe and explains how the existing body of EU law applies to these new business models. In the last part, it makes a few brief comments on the need for future regulation.
Polymeric nanoparticles for siRNA delivery: Production and applications
2017
Gene therapy through the use of siRNA and a polymeric carrier are becoming an efficient therapeutic option to conventional pharmaceutical formulations for the treatment of deadly diseases, such as cancer, pulmonary, ocular and neurodegenerative diseases. However, several considerations regarding the stability, formulation, and efficacy have to be faced up until these systems could be considered to be a marketable pharmaceutical products for to extend siRNA application to clinical practice. This review is focused on the key challenges of siRNA therapeutics, with special attention on the faced obstacles and on the formulation-related difficulties, providing a list of requirements needed for o…

Maahanmuuttajakirjallisuudesta siirtolaiskirjallisuudeksi : siirtolaisuuteen liittyvän kirjallisuuden terminologian perusteet ja uudistaminen
2013
Nyky-Suomessa maahanmuuttajien ja muiden siirtolaisina itseään pitävien kirjoittama kaunokirjallisuus on varsin vähäistä ja muutenkin marginaalista. Siirtolaisuuteen liittyvän kaunokirjallisuuden määrittely on suomen kielessä vakiintumatonta ja ongelmallista. ”Maahanmuuttajakirjallisuus” ja muut nykyisin yleisesti käytössä olevat termit eivät kuvaa ilmiötä riittävän kattavasti ja tarkasti. Tämän tutkimuksen tavoitteena on analysoida vallitsevaa tilannetta ja siltä pohjalta löytää siirtolaisuuteen liittyvälle kaunokirjallisuudelle sopiva suomenkielinen termi. Siirtolaisuuteen liittyvää kirjallisuutta on vanhastaan kutsuttu ”siirtolaiskirjallisuudeksi”, mutta termi on vakiintunut tarkoittamaa…
Application of 3D printed scavengers for improving the accuracy of single-particle inductively coupled plasma mass spectrometry analyses of silver na…
2023
The determination of silver nanoparticles (Ag NPs) with single-particle inductively coupled plasma mass spectrometry can be severely interfered with coexisting dissolved silver causing high background signals, which can lead to inaccurate quantification of NP size and particle concentration. In this paper, chemically active and reusable 3D printed scavengers are applied for highly efficient dissolved silver removal in Ag NP dispersions, allowing more accurate determination of particle concentration and size. Selective laser sintering was used for constructing the porous 3D scavengers constituting of polystyrene used as a supporting material and ion-exchange material SiliaBond Tosic acid (TA…
