How Do Judgmental Overconfidence and Overoptimism Shape Innovative Activity?
2021
Recent field evidence suggests a positive link between overconfidence and innovative activities. In this paper we argue that the connection between overconfidence and innovation is more complex than the previous literature suggests. In particular, we show theoretically and experimentally that different forms of overconfidence may have opposing effects on innovative activity. While overoptimism is positively associated with innovation, judgmental overconfidence is negatively linked to innovation. Our results indicate that future research is well advised to take into account that the relationship between innovation and overconfidence may crucially depend on what type of overconfidence is most…
Innovating in the textile industry: An uncoordinated dance between firms and their territory?
2020
Considering the process of innovati on development, this paper aimed to examine the eff ect of diff erent dimensions of proximity and the level of coordinati on that exists in a texti le cluster. This study employed a qualitati ve method, based on indepth interviews that were conducted with two leading fi rms in a texti le cluster in Valencia, Spain, which is subject to intense competi ti on from producers in Asia. Firms were selected according to the criteria of innovati on development and opportunity. This is a pilot study that precedes a more ambiti ous one. The results suggested that fi rms' innovati ons are developed in an isolated, disconti nuous, marginal, and uncoordinated way, and …
The Wine Influencers: Exploring a New Communication Model of Open Innovation for Wine Producers—A Netnographic, Factor and AGIL Analysis
2020
Wine Influencers (WIs) represent a new type of independent third party endorsers that are progressively establishing themselves within social networks. This study analyzes the characteristics of the activity of WIs and the communication model used via Instagram. Netnographic Analysis, Factor Analysis and AGIL methods were applied. The results show five Key-findings within specific relationships established during discussions: advice from Wine Influencers and generalized reciprocity in relationships
Vaporization and autoignition characteristics of ethanol and 1-propanol droplets : influence of water
2013
Detailed investigation of the vaporization of an isolated of ethanol and 1-propanol droplet was carried out in this experimental study. The experimental set-up consists of a heated chamber with a cross quartz fibers configuration as droplet support. An alcohol droplet is located at the intersection of the cross quartz fibre with a controlled initial diameter (300-600µm). Ambient temperature is varied from 298 to 973K at atmospheric pressure. The quasi-steady theory has been used to compare and to explain all experimental results. The real impact of the water concentration on the vaporization rate of an ethanol droplet is also examined, where two ‘quasi-steady’ periods are observed on the d2…
Synthesis of Combretastatin A-4 and 3′-Aminocombretastatin A-4 derivatives with Aminoacid Containing Pendants and Study of their Interaction with Tub…

Copper-catalyzed regioselective synthesis of (E)-β-fluorovinyl sulfones
2019
Organofluorine compounds are finding increasing application in a variety of fields such as pharmaceutical, agrochemical, and material sciences. However, given the scarcity of fluorine-containing natural products, advancement in this area depends almost entirely on the development of new synthetic methodologies. In this article, we present the synthesis of a series of previously undescribed (E)-&beta
Una reflexión sobre la expulsión de los moriscos valencianos y la repoblación
2009
La historiografía sobre los moriscos y su expulsión ha estado determinada por todo un conjunto de prejuicios ideológicos. Los contemporáneos de la expulsión, al menos los que tuvieron ocasión de expresarse por escrito, adoptaron una posición que podemos llamar moriscófoba. Consideraban que la población morisca valenciana era económicamente poco relevante, dado el carácter minifundista y atrasado de la agricultura que practicaban. Al mismo tiempo pensaban que su población crecía a un ritmo mayor que la cristiana, debido al matrimonio universal y precoz que practicaban, ya que las que llamaban «cargas del matrimonio» eran para ellos poco exigentes y no practicaban el celibato. Los historiador…
Ultrasound as a Promising Tool for the Green Extraction of Specialized Metabolites from Some Culinary Spices
2021
Spices are a popular food of plant origin, rich in various phytochemicals and recognized for their numerous properties. The aim of the study was to evaluate the antioxidant and antimicrobial activity, as well as the content of specialized metabolites, of aqueous extracts of three spice species––garlic (Allium sativum L.), ginger (Zingiber officinalle L.) and turmeric (Curcuma longa L.)––prepared by green extraction methods. Ultrasound treatment increased the chromaticity parameter b value of turmeric and ginger extracts, thus indicating a higher yellow color predominantly due to curcuminoids characteristic of these species. Ultrasound-assisted extraction significantly increased the content …
Water Resource Recovery Facilities (WRRFs): The Case Study of Palermo University (Italy)
2021
The wastewater sector paradigm is shifting from wastewater treatment to resource recovery. In addition, concerns regarding sustainability during the operation have increased. In this sense, there is a need to break barriers (i.e., social, economic, technological, legal, etc.) for moving forward towards water resource recovery facilities and demonstration case studies can be very effective and insightful. This paper presents a new water resource recovery case study which is part of the Horizon 2020 EU Project “Achieving wider uptake of water-smart solutions—Wider Uptake”. The final aim is to demonstrate the importance of a resource recovery system based on the circular economy concept. The r…
Roadmapping the Transition to Water Resource Recovery Facilities: The Two Demonstration Case Studies of Corleone and Marineo (Italy)
2022
The current exploitation of freshwater, as well as the significant increase in sewage sludge production from wastewater treatment plants (WWTPs), represent nowadays a critical issue for the implementation of sustainable development consistent with the circular economy concept. There is an urgent need to rethink the concept of WWTPs from the conventional approach consisting in pollutant removal plants to water resource recovery facilities (WRRFs). The aim of this paper is to provide an overview of the demonstration case studies at the Marineo and Corleone WRRFs in Sicily (IT), with the final aim showing the effectiveness of the resources recovery systems, as well as the importance of plant o…
