Innovazione e Imprenditorialità. Il ruolo degli spin-off universitari.
2013
Oggi il ruolo delle Università non si limita più soltanto alle tradizionali attività di formazione e di ricerca. La cosiddetta Seconda Rivoluzione Accademica ha attribuito alle Università una "terza missione", che consiste nella valorizzazione e commercializzazione della conoscenza accedemica sul mercato. L'Università diviene così "entrepreneurial university" creando valore non solo in termini di conoscenza ma anche di innovazione e sviluppo economico. Il libro intende approfondire il ruolo che le Università rivestono nel processo di trasferimento di conoscenza innovativa al mercato tramite la costituzione di imprese spin-off. Viene evidenziato come, attraverso il supporto di apposite strut…

Knowledge flow in Technological Business Incubators: Evidence from Australia and Israel
2015
The study of the contribution of incubators to economic growth started to gain momentum in the 1980s, following the growth of the incubation phenomenon. While acknowledging the challenge of evaluating incubators׳ outcomes, we shift the focus from incubators׳ performance to their internal processes, in particular, the interrelationships through which the incubator stakeholders share knowledge. The literature suggests that small new ventures tend to fail because they lack managerial experience and ability to raise capital in an early stage. Incubators are expected to overcome these obstacles by offering experienced monitoring skills and by enhancing access to capital at a firm׳s early stage. …
A relational view of start-up firms inside an incubator. The case of the ARCA Consortium
2018
Purpose Analyzing the entrepreneurial ecosystem related to the ARCA consortium, the purpose of this paper is to study the relationships among the start-up firms inside an incubator. Design/methodology/approach Thanks to the adoption of the relationships concentric model and the density concentric model, the paper highlights the role of relational conditions for innovative projects in partnership among the incubated firms. Reflections herein are tested via a qualitative research approach based on a single case study: the ARCA consortium. Findings This research found that about 32 percent of relationships inside the incubator support the emergence of short-term relationships among the incuba…
Castron kastraatio : Pedro Juan Gutiérrezin proosa castrokommunistisen utopian romuttajana
2016
This dissertation explores how Pedro Juan Gutiérrez's fiction corresponds to the Castrocommunist utopia. The study has three goals: (1) to explain how Castro-communism has formed, altered and impacted on Cuban literature; (2) to investigate how Gutiérrez's fiction corresponds to the Castro-communist utopia and ideals; and (3) how his parodic (anti)detective story Nuestro GG en La Habana (2004) is based on and relates to Cuban socialist detective stories, Graham Greene's spy farce Our Man in Havana, Castro-communist historiography and the social, ideological and economic shifts in Cuban society during the 1990s. Previous studies on Gutiérrez's fiction have focused almost exclusively on the a…
Oncomiracidial development, survival and swimming behaviour of the monogenean Sparicotyle chrysophrii (Van Beneden and Hesse, 1863)
2012
Abstract Oncomiracidial development of Sparicotyle chrysophrii , a monogenean parasite of Sparus aurata , was analysed using 450 eggs. Parasite morphological changes in time, data on hatching success, as well as oncomiracidial survival and swimming behaviour were recorded. Eggs were maintained at 20 °C and exposed to LD 12:12. They were observed under the stereomicroscope every 8 h until they hatched. Thereafter, 155 oncomiracidia were isolated in separate wells and observed every 2 h until their death. Most of the hatchings occurred in a short period of time (approximately 24 h). Hatching success was 87% and the hatching period ranged from 5 to 10 days after deposition, with most of the ha…
Régimen de propiedad y trabajo por cuenta propia en Cuba: De 1959 a la nueva Constitución de 2019
2019
En julio de 2018, la Asamblea Nacional de Cuba inició el trámite de discusión de un nuevo proyecto de Constitución, cuya aprobación, mediante referéndum, se produjo en febrero de 2019. Esta Constitución es la concreción jurídico-formal de todo un conjunto de transformaciones sociales y económicas que vienen produciéndose en la isla desde inicios de la década de los 90, con la caída del bloque socialista. El presente artículo lleva a cabo un análisis de las transformaciones que en materia de propiedad y de regulación del trabajo por cuenta propia se han producido durante este período, así como de las novedades que la nueva Constitución introduce en estos aspectos.Recibido: 4 abril 2019Acepta…
Study of the bacillus thuringiensis Cry1Ia protein oligomerization promoted by midgut brush border membrane vesicles of lepidopteran and coleopteran …
2020
Bacillus thuringiensis (Bt) produces insecticidal proteins that are either secreted during the vegetative growth phase or accumulated in the crystal inclusions (Cry proteins) in the stationary phase. Cry1I proteins share the three domain (3D) structure typical of crystal proteins but are secreted to the media early in the stationary growth phase. In the generally accepted mode of action of 3D Cry proteins (sequential binding model), the formation of an oligomer (tetramer) has been described as a major step, necessary for pore formation and subsequent toxicity. To know if this could be extended to Cry1I proteins, the formation of Cry1Ia oligomers was studied by Western blot, after the incuba…
A Simple Phosphine–Diolefin‐Promoted Copper‐Catalysed N‐Arylation of Pyrazoles with (Hetero)aromatic Bromides: The Case of Chloroarenes Revisited
2012
A molecularly defined new phosphine–diolefin cubane copper pre-catalyst used at 1.25 mol % under mild conditions promotes the coupling of pyrazoles to functionalised aryl and heteroaryl bromides, which hold a variety of functional groups. This versatile phosphorus-based system was thus successfully used, under identical conditions, for the coupling of a large scope of heteroaromatics to selectively produce pyridinyl- and pyrimidinyl-pyrazoles, as well as several novel furyl-, thienyl- and thiazolyl-substituted pyrazoles. The careful investigation of coupling with the analogous aryl and heteroaryl chlorides clearly indicated that for specifically activated chloroarenes a direct nucleophilic …
PARA UNA CARACTERIZACIÓN DE LA VARIEDAD CUBANA DEL ESPAÑOL EN LA DÉCADA DEL CUARENTA DECIMONÓNICA. COMENTARIO DE CARTAS
2015
En este artículo se discute si la variedad cubana de la década del 40 del siglo XIX está ya suficientemente diferenciada, y se trata de demostrar, a partir del estudio de un grupo de rasgos tipificadores en una muestra de cartas, que los procesos más importantes, de modo general, no han concluido completamente su cambio.
