Circolazione e sviluppo di un modello metodologico. La critica testuale delle fonti giuridiche romane fra Otto Gradenwitz e Salvatore Riccobono
2018
La ricerca delle interpolazioni, cominciata con la Scula culta, viene ripresa in Germania alla fine del XIX secolo. Fra quanti misero a punto un metodo storico-critico per lo studio delle fonti giuridiche romane va menzionato anche Gradenwitz, che – insieme ad altri studiosi tedeschi – sarebbe stato uno dei maestri di Riccobono. La prima produzione scientifica di Riccobono, che si riconosce nel nuovo indirizzo storico-critico affermatosi in Germania, si avvale dei metodi appresi dai maestri tedeschi. Lungo questo solco, tuttavia, comincia l’elaborazione di un metodo più raffinato, che distingue fra interpolazioni formali e interpolazioni sostanziali e recupera gradualmente altri strumenti d…
The Value of Organic plus. Analysing Consumers’ Preference for Additional Ethical Attributes of Organic food Products
2023
AbstractOrganic Plus attributes strengthen the sustainability of the organic products and differentiate them from the ‘conventionalized’ organic ones. Products with Organic Plus attributes seem appreciated by organic consumers. However, research on consumers’ preference for Organic Plus is still scarce, leaving gaps in the understanding of the consumers’ characteristics of organic products with Plus attributes. In order to enrich the knowledge of consumers’ preference for organic products with Plus attributes, the present study aims to achieve three Objectives: (1) identifying which Plus attributes, among fair prices to local farmers, integration of people with disabilities and eco-friendli…
Combinatorial Double Auction Radio Resource Allocation Model in Crowd Networks
2018
International audience; Industrial Partners (IPs) with Mobile Network Operators (MNOs) are extending the mobile network infrastructure with Small Cells (SCs) in order to meet the growing mobile traffic demand. Due to the increasing number of telecommunication market competitors and the scarcity of radio resources, static sharing schemes are no more efficient. New dynamic schemes should be considered to meet both user expectations and economic success. In a crowd networking context, we propose in this work a dynamic radio resource scheme based on combinatorial double auctions. The participants in these auctions are the MNOs considered as buyers and the IPs, providers of SCs, considered as se…
Damned If You Do and Damned If You Don’t: Two Masters
2018
Available online: 05 June 2018 We study common agency problems in which two principals (groups) make costly commitments to incentives that are conditioned on imperfect signals of the agent's action. Our framework allows for incentives to be either rewards or punishments. For our basic model we obtain a unique equilibrium, which typically involves randomization by both principals. Greater similarity between principals leads to more aggressive competition. The principals weakly prefer punishment to rewards, sometimes strictly. With rewards an agent voluntarily joins both groups with punishment it depends on whether severe punishments are feasible and cheap for the principals. We study whether…
Designing multi-attribute auctions for engineering services procurement in new product development in the automotive context
2010
Abstract In recent years, use of multi-attribute auctions has been consolidating as a powerful mechanism in procurement settings where multiple drivers affect the transaction outcome. This paper provides a project management approach for multi-attribute auction design for standardized engineering services procurement in the context of new product development in automotive industry. Two variables are taken into account in the bidding process: price and duration of the given engineering activity. From a theoretical viewpoint, we fully determine optimal suppliers’ bidding strategies and expected outcomes, i.e. score/utility, price and duration, for the buyer under both first score sealed bid a…
IncentMe: Effective Mechanism Design to Stimulate Crowdsensing Participants with Uncertain Mobility
2018
Mobile crowdsensing harnesses the sensing power of modern smartphones to collect and analyze data beyond the scale of what was previously possible with traditional sensor networks. Given the participatory nature of mobile crowdsensing, it is imperative to incentivize mobile users to provide sensing services in a timely and reliable manner. Most importantly, given sensed information is often valid for a limited period of time, the capability of smartphone users to execute sensing tasks largely depends on their mobility pattern, which is often uncertain. For this reason, in this paper, we propose IncentMe, a framework that solves this core issue by leveraging game-theoretical reverse auction …
A breath of fresh air: french books in the Catalogues of the 18th century of the bookshop Mallén of Valencia
2013
Los Catálogos de libros constituyen junto a las subastas de libros y los inventarios de bibliotecas las fuentes más importantes para el estudio del mundo del libro durante el siglo XVIII. A través del estudio de los libros franceses procedentes de los Catálogos de la familia Mallén de libreros de Valencia se pretende conocer mejor los autores y obras que circularon en la ciudad, además de los circuitos, proveedores y clientes de tal comercio. Un negocio que contribuyó a modernizar las estructuras culturales y políticas del momento. The Catalogues of books constitute close to the auctions of books and the inventories of libraries the most important sources for the study of the world of the b…
Potential and limitation of combining terrestrial and marine growth records from Iceland
2017
Abstract Seasonally formed, perennial growth increments of various organisms may possibly contain information about past environmental changes, well before instrumental measurements occurred. Such annually resolved proxy records have been mainly obtained from terrestrial archives, with a paucity of similar data originating from marine habitats. Iceland represents ideal conditions to develop both, tree ring (dendro) and bivalve shell (sclero) chronologies from adjacent sites. Here we introduce the first network of Icelandic birch (Betula pubescens Ehrh.) and rowan (Sorbus aucuparia) dendrochronologies, as well as ocean quahog (Arctica islandica L.) sclerochronologies. In order to identify th…
Wine - investment: a profitable alternative investment or a simple long term pleasure?
2014
International audience; The purpose of this work is twofold: - to make a first historic analysis of performance through an investment in wine by comparing its performance with those that would have been possible to obtain at the same time by providing financial term investments; - to introduce the regional diversity of performance by considering the situation in the three selected geographic areas.
A Binary Particle Swarm Optimization Algorithm for a Double Auction Market
2007
In this paper, we shall show the design of a multi-unit double auction (MDA) market. It should be enough robust, flexible and sufficiently efficient in facilitating exchanges. In a MDA market, sellers and buyers submit respectively asks and bids. A trade is made if a buyers bid exceeds a sellers ask. A sellers ask may match several buyers bids and a buyers bid may satisfy several sellers asks. The trading rule of a market defines the organization, information exchange process, trading procedure and clearance rules of the market. The mechanism is announced before the opening of the market so that every agent knows how the market will operate in advance. These autonomous agents pursue their o…
