La conclusione del contratto informatico nella contrattazione internazionale

Nel corso del presente studio si è cercato di capire quale potesse essere la normativa applicabile ai vari tipi di contratto elettronici analizzati, sia dal punto di vista del diverso modello contrattuale e sia dal punto di vista del soggetto, come parte del contratto. Infatti, proprio la peculiare logica delle norme poste a tutela del consumatore giustifica un separato approfondimento degli aspetti riguardanti i contratti conclusi tra operatori professionali, contratti business to business e quelli di cui sia parte un consumatore, contratti business to consumer. Sulla base di questi aspetti soggettivi e contrattuali, è stata analizzate la normativa comunitaria di riferimento, dal regolamento n. 44 del 2001 alla direttiva comunitaria 2000/31/CE. Si sono affrontati anche gli aspetti relativi alle norme di derivazione Uncitral, dalla Model Law del 1996 alla Convenzione del 2005 sulle comunicazioni elettroniche nella contrattazione internazionale, le norme di soft law, dalla Nuova lex mercatoria ai Principi Unidroit alle Linee Guida OCSE e la loro interazione con il commercio elettronico. In seguito, si è analizzata la convenzione di Roma sulle obbligazioni contrattuali e il regolamento Roma I, le loro differenze e la loro diretta applicabilità, se esiste, con il commercio elettronico. In particolare, il Regolamento Roma I ha, nella maggior parte delle sue disposizioni, riproposto quanto contenuto nella convenzione di Roma, però in chiave moderna, apportando delle innovazioni nel commercio elettronico internazionale.

Enabling a direct path from end-user specifications to executable protocols in a biology laboratory environment

Biomedical analyses are becoming increasingly complex, with respect to both the type of the data to be produced and the procedures to be executed. This trend is expected to continue in the future. The development of information and protocol management systems that can sustain this challenge is therefore becoming an essential enabling factor for all actors in the field. The use of custom-built solutions that require the biology domain expert to acquire or procure software engineering expertise in the development of the laboratory infrastructure is not fully satisfactory because it incurs undesirable mutual knowledge dependencies between the two camps. We propose instead an infrastructure concept that enables the domain experts to express laboratory protocols using proper domain knowledge, free from the incidence and mediation of the software implementation artefacts. In the system that we propose this is made possible by basing the modelling language on an authoritative domain specific ontology and then using modern model-driven architecture technology to transform the user models in software artefacts ready for execution in a multi-agent based execution platform specialized for biomedical laboratories.

Consumer Perception and Willingness to Pay for Local Food

A growing number of empirical studies recently investigated consumers' valuation for local food products. However, different aspects related to the local food consumption still remain vague or unexplored. As such, the objective of the present research is to fulfill the existing literature using a mixed methodological approach for the investigation of consumers' preferences and Willingness to Pay (WTP) for local food products. First of all, local food is still a blurred concept and this factor might be source of individuals' misperception for the local origin meaning. Therefore, a qualitative research has been performed in order to investigate the meaning and the perception of the local food in the Italian food market. Results from this analysis have been used as inputs for the building of a non-hypothetical Real Choice Experiment (RCE) to estimate consumers' WTP for locally and organically produced apple sauce. The contribution of this study is three-fold: (1) consumers' valuation for the local origin is interpreted in terms of regional borders, over the organic food claim in case of an unusual food product in the area of interest, (2) the interaction between individuals' personality traits and consumers’ preferences for local and organic foods is analyzed, (3) the role of Commitment Cost creation in consumers' choice making in case of uncertainty due to the use of a novel food product and of an unconventional food claim is investigated. Results suggest that consumers are willing to pay a higher price premium for organic over locally produced apple sauce, possibly because of the presence of a regulated certification. In accordance with Commitment Cost theory, the organic label might thus decrease consumers' uncertainty for the features of the product in question. Results also indicate that individuals' personality can be source of heterogeneity in consumers' preferences.
