Montalcino e il suo Brunello : evoluzione e affermazione
No full textThere is a crucial question, related to the reasons why Montalcino, a land where its wine is appreciated for centuries, until the end of the Sixties of the Twentieth Century, has not developed the wine potential production that it held. It is a complex process which interweaves the most important historical events of the Italian Twentieth Century and often played a key role in the realization of the enormous heritage that Montalcino people had at their disposal. Two world wars, the economic boom of the Fifties and the serious state of crisis, in which the countryside went through, didn’t certainly encouraged a production that only in the Eighties became a real source of pride for the Italian viticulture in the world. The winning formula for Brunello di Montalcino was the fellowship between tradition and marketing, respectively represented by Biondi Santi family and Villa Banfi, after having achieved the authorization for DOC before and DOCG after. The history of this famous wine and men, who have been able to build with wise dedication the value and image of Montalcino, outlines a process in which the original values of the rural world are completed in a more modern approach to doing business. Even after the unpleasant events of Brunellopoli, Montalcino, already strong and aware of the immense heritage in its possession, managed to release an icon that, though for short time, was likely to be compromised.Abordant la question de la naissance et de l’évolution d’un territoire viticole d’excellence tel le Montalcino, s’impose une interrogation de fond : pourquoi cette terre, dont ses vins sont appréciés depuis des siècles, n’a pas développé entièrement son potentiel productif jusqu’à la fin des années Soixante du XXe siècle ? La réponse remporte à un parcours complexe étroitement lié aux événements historiques italiens les plus importants du siècle dernier, lesquels ont joué un rôle clé dans la pris de conscience parmi les habitants de Montalcino de l’immense patrimoine dont ils disposent. Deux guerres mondiales, le boom économique des années Cinquante et l’état de crise des campagnes ont empêché l’évolution productive du vin, qui devienne une véritable source de fierté pour la viticulture italienne seulement dans les années Quatre-vingt. La formule gagnante pour le Brunello di Montalcino a été la liaison entre la tradition et la commercialisation, respectivement représentées par la famille Biondi Santi et Villa Banfi, après avoir obtenu les appellation d’origine DOC et, ensuite, DOCG. L’histoire de ce vin célèbre et des hommes qui ont su construire avec dévouement et compétence la valeur et l’image de Montalcino esquisse un chemin structuré, où les valeurs originelles du monde rural se sont combinées avec une approche plus moderne de faire des affaires. Même après les événements malheureux de Brunellopoli du 2008, Montalcino, désormais solide et consciente de l’immense richesse qu’il possède, a réussi à racheter une image, quoique pour peu de temps, a risquée d’être irrémédiablement compromise
Reasoning on LTL on Finite Traces: Insensitivity to Infiniteness
No full textIn this paper we study when an LTL formula on finite traces (LTLf formula)isinsensitivetoinfiniteness,thatis,itcanbe correctly handled as a formula on infinite traces under the assumption that at a certain point the infinite trace starts re- peating an end event forever, trivializing all other propositions to false. This intuition has been put forward and (wrongly) assumed to hold in general in the literature. We define a neces- sary and sufficient condition to characterize whether an LTLf formula is insensitive to infiniteness, which can be automati- cally checked by any LTL reasoner. Then, we show that typical LTLf specificationpatternsusedinprocessandservicemod- eling in CS, as well as trajectory constraints in Planning and transition-basedLTLf specificationsofactiondomainsinKR, are indeed very often insensitive to infiniteness. This may help to explain why the assumption of interpreting LTL on finite and on infinite traces has been (wrongly) blurred. Possibly be- cause of this blurring, virtually all literature detours to Bu ̈chi automata for constructing the NFA that accepts the traces satis- fying an LTLf formula. As a further contribution, we give a simple direct algorithm for computing such NFA
Monitoring Constraints and Metaconstraints with Temporal Logics on Finite Traces
No full textRuntime monitoring is a central operational decision support task in business process management. It helps process executors to check on-the-fly whether a running process instance satisfies business constraints of interest, providing an immediate feedback when deviations occur. We study runtime monitoring of properties expressed in ltlf, a variant of the classical ltl (Linear-time Temporal Logic) that is interpreted over finite traces, and in its extension ldlf, a powerful logic obtained by combining ltlf with regular expressions. We show that ldlf is able to declaratively express, in the logic itself, not only the constraints to be monitored, but also the de facto standard rv-LTL monitors. On the one hand, this enables us to directly employ the standard characterization of ldlf based on finite-state automata to monitor constraints in a fine-grained way. On the other hand, it provides the basis for declaratively expressing sophisticated metaconstraints that predicate on the monitoring state of other constraints, and to check them by relying on standard logical services instead of ad hoc algorithms. We then report on how this approach has been effectively implemented using Java to manipulate ldlf formulae and their corresponding monitors, and the RuM rule mining suite as underlying infrastructure
GEOGRAFIE DEL VINO: COSTRUZIONE STORICA E PATRIMONIALIZZAZIONE DEI PAESAGGI VITICOLI
No full textThis research project is supposed to face up viticulture in a complex, epistemological framework. As Dickenson and Salt affirm the geography of the wine «may be studied from a variety of perspectives and encompasses the influence of the physical environment, historical diffusion of the vine and viticulture, economic geographies of cultivation and marketing, political influences on trade and production, and cultural perceptions of landscapes, product and people». After all, already in the Latin etymology of viticulture exists a deep content hiatus that imposes to consider two fair enough different concepts; indeed, culture may refer to cultivation and care. Therefore, it is crucial to understand how viticulture must be considered and to show the way its dichotomic nature may suggest distant methodologies of investigation.
After having underlined the epistemological framework of viticulture in relationship to geography and given the interpretative tools of the research, I analyzed the construction and the evolution of some viticultural landscapes (Montalcino, Barolo, Bolgheri and the Côte d’Or) whose choice depends on the dynamics that regarded their production (characterized by a particular propensity to commercialization), the relationships and the differences among them and finally the essential relationship that wine creates with its territory of origin. The role of the tradition represents the fil rouge that links these experiences and it declines in a different perspective according to the realities I analyzed. However, for each of them, it has been fundamental the role developed by a forerunner; indeed, Ferruccio Biondi for Brunello di Montalcino, Juliette Colbert-Falletti for Barolo and Mario Incisa della Rocchetta for the Sassicaia have not only contributed to the creation of a wine but generally to the development of a whole territory that is identified today in the cultivation of the grapevine.
Finally, in virtue of such a rooted and shared historical construction, these territories take part in the processes of patrimonialization that are characterizing some wine regions to a global scale. Following different criterions of classification, where however viticulture covers a preponderant aspect, Val d’Orcia, Langhes and the climats de Bourgogne are considered from the UNESCO a human world heritage to safeguard while Bolgheri has been inserted by Regione Tuscana in the catalog of the historical rural landscapes; in all these cases, independently from who promoted the patrimonialization, the aim is clear: to allow the future generations to enjoy the cultural and environmental wealth that distinguish them. The wine landscapes are reported to be the ones that underwent fast and important transformations. Moving from this, I underline the debate around the relationship between patrimonialization (considered as a specific process of conservation) and the general transformation of the landscape. From this perspective, the criterions of patrimonialization adopted for the viticultural landscapes seem not to consider the eventuality of one change in the case wine shouldn’t play the social and economic role that it has nowadays. What would it happen in that case
Relationship between cerebrospinal fluid beta-endorphin and plasma pituitary-gonadal hormone levels in women.
No full textBrain beta-endorphin (beta-EP) plays an important role in regulating the hypothalamus-pituitary-gonadal axis activity. Cerebrospinal fluid (CSF) beta-EP levels seem to reflect the central rather than pituitary secretion. With the aim to correlate the changes of plasma estradiol (E2), progesterone, luteinizing hormone (LH) and follicle-stimulating hormone with brain beta-EP, CSF levels of beta-EP were measured in 15 normally cycling and 15 postmenopausal women. CSF beta-EP levels in post-menopausal women were lower than in fertile women. A positive correlation between plasma E2 and CSF beta-EP level was found in all women. In fertile women CSF beta-EP levels were inversely correlated to plasma gonadotropin levels. These results showed that CSF beta-EP levels differ between fertile and postmenopausal women and are correlated with plasma LH and E2, suggesting a strong linkage between central beta-EP levels and pituitary-gonadal axis hormones

No full textVerification of description logic Knowledge and Action Bases
No full textWe introduce description logic (DL) Knowledge and Action Bases (KAB), a mechanism that provides both a semantically rich representation of the information on the domain of interest in terms of a DL KB and a set of actions to change such information over time, possibly introducing new objects. We resort to a variant of DL-Lite where UNA is not enforced and where equality between objects may be asserted and inferred. Actions are specified as sets of conditional effects, where conditions are based on epistemic queries over the KB (TBox and ABox), and effects are expressed in terms of new ABoxes. We address the verification of temporal properties expressed in a variant of first-order μ-calculus where a controlled form of quantification across states is allowed. Notably, we show decidability of verification, under a suitable restriction inspired by the notion of weak acyclicity in data exchange. © 2012 The Author(s)
Abducing Compliance of Incomplete Event Logs
No full textThe capability to store data about business processes execution in so-called Event Logs has brought to the diffusion of tools for the analysis of process executions and for the assessment of the goodness of a process model. Nonetheless, these tools are often very rigid in dealing with Event Logs that include incomplete information about the process execution. Thus, while the ability of handling incomplete event data is one of the challenges mentioned in the process mining manifesto, the evaluation of compliance of an execution trace still requires an end-to-end complete trace to be performed. This paper exploits the power of abduction to provide a flexible, yet computationally effective, framework to deal with different forms of incompleteness in an Event Log. Moreover it proposes a refinement of the classical notion of compliance into strong and conditional compliance to take into account incomplete logs
