Perception of melodic complexity: a cross-cultural investigation
2002
Perception of quality and complexity in wine and their links to varietal typicality: An investigation involving Pinot noir wine and professional tast…
2020
International audience; Quality and complexity are abstract terms employed frequently to describe a wine's overall attributes. In the present study, we investigated: (i) attributes driving wine professionals' judgments of quality and complexity in Pinot noir wines; (ii) the relation between these two abstract concepts; and (iii) association of each concept with varietal typicality. Twenty-two wine professionals evaluated 18 New Zealand Pinot noir wines in both clear and opaque glassware via two sensory tasks, a descriptive rating task and an 8-attribute, perceived complexity questionnaire. Sensory data were associated with wine UV-spectrophotometry colour measures to aid interpretation of t…

Mappe della contemporaneità. Visualizzare la complessità per vivere, comprendere, partecipare.
2020
Si propone una riflessione sulle modalità di visualizzazioni della complessità di contesti territoriali, rese possibili dalle tecnologie dell’informazione connesse agli open data; uno scenario che evidenzia la rilevanza oggi di strumenti e competenze del design della comunicazione e dell’informazione, proponendo una nuova centralità della “mappa”, strumento e modello contemporaneamente di conoscenza, rappresentazione e trasformazione del mondo. Il contributo indaga come le diverse declinazioni di visual mapping, che connettono un contesto reale fisico-geografico ai molteplici livelli di informazione disponibili, possono alimentare nei cittadini consapevolezza e partecipazione a supporto di …
Complexity and Action. A Cybernetics Perspective to Decision Making - Plenary Lecture
2013
The problem often faced by some approaches to complexity is that of the abstraction from the competition character of action. Man often is not rational, because of his cognitive limits, his heuristics of thought, and his passions of which the most dangerous is fear. To be aware that the world is complex and there is no way to forecast the future is something that can scare at the point to inhibit decision and necessary action. Today there is a lot of talking about how the world, hence the markets, the social and business environment is complex, but few real proposals about what to do. The temptation coming from reductionist models and the reason why they are still so strong in the manageria…
Consulting of the XXI Century. Coping with Complex Business Systems
2011
The increase of the social and economic complexity causes frequent discontinuities and the rapid change of the business environment, triggering intense transformations of the competitive logics and of the capability of forecasting using traditional models. The new competitive reality is characterized by dynamism, connectivity, non–linearity and emergent properties, in other words by “complexity”. The XX century’s myth of the “one best way” reveals its weaknesses and its inability to deal with the new emerging problems and opportunities, which, at the beginning of the XXI century, fIrms have to face. The traditional reductionist concept of “one best way”, based on the “replication of standar…
Una relación dialógica improbable: Edgar Morin/Heinrich Schenker. Hacia una teoría de la complejidad para el sistema tonal.
2009
La presente tesis toma como referencia principal el paradigma de la Complejidad deEdgar Morin y las teorías de Heinrich Schenker. Como emergencia del sistema humanomente/cerebro, el Arte en general y la música en particular son considerados desde la perspectivade las organizaciones de nuestro universo. Así, todos los acontecimientos/eventos que seproducen en el interior/exterior de una composición tonal, lo hacen en función de suantagonismo y complementariedad, siempre de forma concurrente, tal y como articula lasnociones Edgar Morin, consiguiendo superar, a través de la noción de bucle, la dicotomíaoccidental.En las teorías tradicionales de la música, lo descriptivo, lo lineal y lo determi…
Probabilistic Logic under Coherence: Complexity and Algorithms
2005
In previous work [V. Biazzo, A. Gilio, T. Lukasiewicz and G. Sanfilippo, Probabilistic logic under coherence, model-theoretic probabilistic logic, and default reasoning in System P, Journal of Applied Non-Classical Logics 12(2) (2002) 189---213.], we have explored the relationship between probabilistic reasoning under coherence and model-theoretic probabilistic reasoning. In particular, we have shown that the notions of g-coherence and of g-coherent entailment in probabilistic reasoning under coherence can be expressed by combining notions in model-theoretic probabilistic reasoning with concepts from default reasoning. In this paper, we continue this line of research. Based on the above sem…
Probing the origin of ultra-high-energy cosmic rays with neutrinos in the EeV energy range using the Pierre Auger Observatory
2019
Neutrinos with energies above 1017 eV are detectable with the Surface Detector Array of the Pierre Auger Observatory. The identification is efficiently performed for neutrinos of all flavors interacting in the atmosphere at large zenith angles, as well as for Earth-skimming τ neutrinos with nearly tangential trajectories relative to the Earth. No neutrino candidates were found in ∼ 14.7 years of data taken up to 31 August 2018. This leads to restrictive upper bounds on their flux. The 90% C.L. single-flavor limit to the diffuse flux of ultra-high-energy neutrinos with an Eν -2 spectrum in the energy range 1.0 × 1017 eV -2.5 × 1019 eV is E2 dNν/dEν < 4.4 × 10-9 GeV cm-2 s-1 sr-1, placing str…
Ferro- and Antiferromagnetic Interactions in Oxalato-Centered Inverse Hexanuclear and Chain Copper(II) Complexes with Pyrazole Derivatives.
2021
Two novel copper(II) complexes of formulas {[Cu(4-Hmpz)4][Cu(4-Hmpz)2(µ3-ox-κ2O1,O2:κO2′:κO1′)(ClO4)2]}n (1) and {[Cu(3,4,5-Htmpz)4]2[Cu(3,4,5-Htmpz)2(µ3-ox-κ2O1,O2:κO2′:κO1′)(H2O)(ClO4)]2[Cu2(3,4,5-Htmpz)4(µ-ox-κ2O1,O2:κ2O2′,O1′)]}(ClO4)4·6H2O (2) have been obtained by using 4-methyl-1H-pyrazole (4-Hmpz) and 3,4,5-trimethyl-1H-pyrazole (3,4,5-Htmpz) as terminal ligands and oxalate (ox) as the polyatomic inverse coordination center. The crystal structure of 1 consists of perchlorate counteranions and cationic copper(II) chains with alternating bis(pyrazole)(µ3-κ2O1,O2:κO2′:κO1′-oxalato)copper(II) and tetrakis(pyrazole)copper(II) fragments. The crystal structure of 2 is made up of perchlorat…
