Economic assessment of sicilian loquat orchards
2015
The majority of Italian production of loquat (Eriobotrya japonica) derives from the Palermo province, along the northern Sicilian coast. However, this area is characterized by family orchards, traditional cultural techniques, and inadequate commercial organization. These appear to affect negatively the production costs and reduce the farmersâ income, decreasing the competitiveness of Sicilian loquat orchards. This study evaluates the economic viability of Sicilian loquat orchards by means of cost-benefit analysis (CBA). In particular, for the investment assessment some financial indicators have been calculated such as net present value (NPV), discounted payback time (DPBT), and internal r…
Hydroquinone derivatives from the marine-derived fungus Gliomastix sp.
2017
Eight new hydroquinone derivatives, gliomastins A–D (1–4), 9-O-methylgliomastin C (5), acremonin A 1-O-β-D-glucopyranoside (6), gliomastin E 1-O-β-D-glucopyranoside (7), and 6′-O-acetyl-isohomoarbutin (8), together with seven known analogues were isolated from the marine-derived fungus Gliomastix sp. Their structures were elucidated by extensive spectroscopic analysis including 1D and 2D NMR measurements aided by DFT NMR calculations as well as MS data. TDDFT-ECD and OR calculations were performed to determine the absolute configurations of 1 and the aglycones of 6 and 7. Compound 1 features a novel skeleton, biogenetically derived from a Diels–Alder reaction between derivatives of 11 and 1…
The nutritional composition of selected wild edible mushrooms from Sicily (southern Italy)
2011
The wide consumption of wild fungi by the local population is the basis for an evaluation of the as yet unknown nutritional composition of some selected species. Wild edible mushrooms (Fistulina hepatica, Infundibulicybe geotropa, Laetiporus sulphureus, Macrolepiota procera var. procera and Suillus granulatus) were collected in a number of Sicilian (southern Italian) forest ecosystems and analysed according to standard methodologies of fungal analysis, for their basic composition (ash, water, protein, fat, carbohydrate and vitamin). The results showed that the investigated mushrooms could be suggested as a source of nutritional elements for the human diet.
Turnover ratios and profitability ratios calculation methods: the book or average value
2019
The scientific literature of the turnover ratios and profitability ratios calculation offers to use book or average value of balance sheet calculation methods. Different schools of financial analysis nowadays offer many variations of the ratio calculations and even though the components of ratio formulas change, the meaning stays the same. The aim of this research is to analyze the turnover and profitability ratios, to study the different methods of calculation, based on different schools of financial analysis and empirical research results, and to create proposals for companies for the use of these methods for financial analysis. The authors of this paper are using the international scient…
Celebrity endorsement: influence of fan identification and brand collision on brand awareness and perceived value
2020
El deporte es un fenómeno social y económico en continua expansión, que contribuye a la prosperidad y la solidaridad en los países desarrollados (Aragonés, 2014). Ha sido reconocido por el Comité Olímpico Internacional como una herramienta para el fomento de la paz y las relaciones entre diferentes culturas. En relación a su vertiente económica, sobre la que se centra la presenta tesis doctoral, los ingresos generados fueron de 127 millones de euros en 2015, tal y como habían señalado las previsiones (PWC, 2011) y dio empleo a 1.700 millones de europeos en 2016 (Eurostat, 2018). Además, dada su pujanza y crecimiento en las últimas décadas, la industria del deporte ha sido objeto de interés …
Ripostigli di bronzi nella Sicilia di età arcaica. Contesti di rinvenimento, funzioni e aspetti ponderali
2012
The contribution analyzes the structure, composition and contexts of the archaic age bronze hoards found in the colonial and anellenic sites of Sicily. The particular frequency of hoards in sacred areas is evident, where they are consecrated to the chthonic divinities due to their intrinsic value, linked to their metallic nature and their notion of weight.
Sustainable Value Co-Production and Co-Creation in Virtual Reality: An Exploratory Research on Business-to-Business Interactions
2022
The objective of this study is to identify the environment for business interactions in virtual reality in the value co-production and co-creation process and to understand how such an environment enables the sustainable development of co-creational activities. This paper takes the concepts of value co-production and co-creation and presence and the Actors, Resources, and Activities Model as conceptual references for the exploration of interactions in virtual reality. Using ten in-depth interviews with senior managers, this paper takes an exploratory case analysis perspective. Results show how the sense of presence—level of immersion to which a medium that produces seemingly accurate repres…
Simulation of laser-generated ultrasonic wave propagation in solid media and air with application to NDE
2009
Ultrasonic methods are well known as powerful and reliable tool for defect detection. In the previous decades focus and interest have been directed to non-contact sensors and methods, showing many advantages over contact techniques where inspection depends on contact conditions (pressure, coupling medium, contact area). The non-contact hybrid ultrasonic method described here is of interest for many applications, requiring periodic inspection in service or after manufacturing. Despite the potential impact of laser-generated ultrasound in many areas of industry, robust tools for studying the phenomenon are lacking and thus limit the design and optimization of non-destructive testing and evalu…
AN AGENT BASED ARCHITECTURE FOR MANUFACTURING E-MARKETPLACES
2005
This chapter presents the Agent Based Architecture developed within the research project, titled "Process and Production Planning in manufacturing Enterprise Networks". As mentioned in Chapter 1, the architecture has been developed to support “added value services” in neutral linear e-marketplaces, i.e. in virtual districts. In this chapter the architecture will be described from a functional and dynamic point of view by using the formalisms used in the project. In particular, from a functional perspective, the architecture is described by using the IDEF0 formalism, while its dynamics are specified by UML activity diagrams.
OPPORTUNITIES OF THE DEVELOPMENT OF VALUES IN THE INTEREST-RELATED EDUCATION OF ADOLESCENTS
2018
Many schools and different educational institutions offer a wide range of out-of-class activities that promote the development of adolescents for a world in which people need to collaborate, to trust each other, to respect other people, different views and traditions. These activities deepen the knowledge acquired in the class in different school subjects, music, art, the use of modern technologies and in other fields. Interest-related education (out-of-class) activities support school teachers and parents in the process of the development of skills, abilities and personal traits, values for life. The task of any teacher in schools and out-of-school activities is to integrate the developmen…
