Macrofungi as ecosystem resources: Conservation versus exploitation

2013

Fungi are organisms of significant importance not only for the crucial roles they undertake in nature but also for many human activities that are strictly dependent on them. Indeed, fungi possess fundamental positions in ecosystems functioning including nutrient cycles and wood decomposition. As concerns human-related activities, edible and non-edible mushrooms are also involved and/or exploited in forestry, pharmaceutical industry and food production; hence, nowadays they represent a major economic source worldwide. In order to maintain and improve their strategic importance, several conservation strategies, such as habitat preservation, are needed. This article reports several contributio…

Learning from foreign operation modes: The virtuous path for innovation

2020

In this article, we analyze the impact of learning from internationalization on small and medium enterprises’ (SMEs) performance along different development paths. Drawing on the exploitation versus exploration logic, we use an alternative view of foreign operation modes (the learning perspective) to provide insights into the impact of such learning on technological and organizational innovation as well as overall performance. Our results, which are derived from a sample of 132 SMEs active in traditional manufacturing industries, point to a path to superior performance that entails resource-augmenting operation modes and organizational innovation.

Institutional resources as a source of trade union power in Southern Europe

2017

Abstract Institutional resources are one of four sources of power available to trade unions (Gumbrell –McCormick and Hyman, 2013). Literature has tended to pay more attention to associational and organizational power and to emphasize the indispensable but problematic character of institutional resources. This paper examines the role of institutional resources in three Southern European countries (Greece, Portugal and Spain) which share common characteristic including post dictatorship political settlements; recent economic crises; external intervention. Comparative analysis draws out the distinctive role and character of institutional resources in Spanish industrial relation. It shows how t…

Functional ecological patterns and the effect of anthropogenic disturbances on a recently restored Mediterranean coastal lagoon. Needs for a sustaina…

2012

Abstract We present here a detailed case study on the lessons learned after a restoration process of a natural ecosystem, which can be considered as an ecological experiment. Senillar de Moraira is a brackish water small coastal lagoon located in the Spanish Mediterranean coast. It is separated from the sea by a sand bar and a beach, and is regularly fed by groundwater. Mostly due to the strong anthropogenic pressure this lagoon was degraded, and a restoration process, consisting mostly on the rebuilt of hydrogeomorphological features, was accomplished about a decade ago. After the restoration project, ecological monitoring was performed to reveal the recovery of the ecological integrity of…

DiDuSoNet: A P2P architecture for Ditributed Dunbar-based Social Networks,

2015

Online Social Networks (OSNs) are becoming more and more popular on the Web. Distributed Online Social Networks (DOSNs) are OSNs which do not exploit a central server for storing users data and enable users to have more control on their profile content, ensuring a higher level of privacy. In a DOSN there are some technical challenges to face. One of the most important challenges is the data availability problem when a user is offline. In this paper we propose DiDuSoNet, a novel P2P Distributed Online Social Network where users can exercise full access control on their data. Our system exploits trust relationships for providing a set of important social services, such as trustness, informati…

Trusted dynamic storage for dunbar-based P2P online social networks

2014

Online Social Networks (OSNs) are becoming more and more popular in today's Internet. Distributed Online Social Networks (DOSNs), are OSNs which do not exploit a central server for storing users' data and enable users to have more control on their profile content, ensuring a higher level of privacy. The main challenge of DOSNs comes from guaranteeing availability of the data when the data owner is offline. In this paper we propose a new P2P dynamic approach to the problem of data persistence in DOSNs. By following Dunbar's approach, our system stores the data of a user only on a restricted number of friends which have regular contacts with him/her. Users in this set are chosen by considerin…

Mumijo traditional medicine: fossil deposits from Antarctica (chemical composition and beneficial bioactivity)

2008

Mumijo is a widely used traditional medicine, especially in Russia, Altai Mountains, Mongolia, Iran Kasachstan and in Kirgistan. Mumijo preparations have been successfully used for the prevention and treatment of infectious diseases; they display immune-stimulating and antiallergic activity as well. In the present study, we investigate the chemical composition and the biomedical potential of a Mumijo(-related) product collected from the Antarctica. The yellow material originates from the snow petrels,Pagodroma nivea. Extensive purification and chemical analysis revealed that the fossil samples are a mixture of glycerol derivatives.In vitroexperiments showed that the Mumijo extract caused in…

Exploiting social comparison using pervasive displays and mobile notifications for reducing energy consumption

2017

Abstract Public displays have been used as a persuasive technology in many prior works. In this paper, we describe a persuasive pervasive system aimed at influencing users’ behavior for reducing energy consumption in buildings. This system exploits a pervasive display that visualizes the energy consumption in different levels (rooms, floors, and buildings), exploiting social comparison techniques. Moreover, our system may be extended by means of a mobile application that sends persuasive personalized messages to the users regarding their energy consumption. We then present our evaluation study design, aimed at comparing the effectiveness of three possible implementation of our system: one b…

Taxonomic identity, geographic distribution and commercial exploitation of the culinary-medicinal mushroom Pleurotus nebrodensis

This work provides an updated overview of an investigation carried out in Europe and elsewhere on the culinary-medicinal mushroom Pleurotus nebrodensis. In particular, the taxonomic identitiy of P. nebrodensis and other related oyster mushrooms with entirely white to cream basidiomata that grow on different plants of the family Apiaceae, is clarified. The differences in the cultivation techniques, the quality of product sold and the sales price in Europe and Asia are also highlighted. Taking also into consideration the importance of P. nebrodensis from the medicinal point of view, it appears appropriate to proceed with a verification of the commercial strains currently available in the inte…
