Cybernetics of Value Co-creation

2014

The paradigm shift from value creation to value "co-creation" calls for a deeper grasp of organizational learning in marketing theory. This paper adopts a cybernetic view of the process of value co-creation to shed light on its relevant aspects and to supply a framework to implement operations and strategies to foster this process. Can cybernetics help to better understand the process of value co-creation? Can the Viable System Model (Beer, 1979) be a sound approach to shape a more effective value co-creation process able to achieve higher satisfaction and value? In this theoretical paper we will show how cybernetic can be effectively used to give a positive answer to both questions above

Attitude and speed in young people. Implementation of a program of driver education

2009

Contemporary Theories of change of attitudes defends that these depends on the way to think, to act and to feel of the people. If we touch upon each one of these three main components related between we can influence in the predisposition to act. The application of a program of speed self-control to ample of young drivers, using a design pretest- postest with control group and using a Factor Analysis shows that is possible the change of attitudes.

"Scrisse di tutto e fu sempre lui": Orio Vergani e la parabola di "Legioni e Falangi" tra reportage e racconto.

2015

Nel microcosmo degli scritti di un “attivista della notizia fresca e della sensazione vissuta” quale è Orio Vergani novelliere, romanziere, autore di opere teatrali, modulato sulla “doppia tastiera” del reportage e dell’invenzione letteraria, si staglia il rapporto con la Spagna, crogiuolo da cui si genera la collaborazione con “Legioni e Falangi”. Si può ricondurre al luglio del 1936 la matrice del lungo racconto della vita della penisola iberica, così come si delinea sulle colonne del periodico, attraverso gli articoli dello scrittore, durante il triennio della militanza ideologica della rivista, dal 1940 al 1943. A quell’estate risale, infatti, la reclusione, per mano anarchica, del gior…

Absolute Humidity Influences the Seasonal Persistence and Infectivity of Human Norovirus

2014

ABSTRACT Norovirus (NoV) is one of the main causative agents of acute gastroenteritis worldwide. In temperate climates, outbreaks peak during the winter season. The mechanism by which climatic factors influence the occurrence of NoV outbreaks is unknown. We hypothesized that humidity is linked to NoV seasonality. Human NoV is not cultivatable, so we used cultivatable murine norovirus (MNV) as a surrogate to study its persistence when exposed to various levels of relative humidity (RH) from low (10% RH) to saturated (100% RH) conditions at 9 and 25°C. In addition, we conducted similar experiments with virus-like particles (VLPs) from the predominant GII-4 norovirus and studied changes in bin…

A Viable System View of the Japanese Lean Production System

2011

We highlight the main characteristics of lean production and we analyze them using a viable-systemic perspective. Doing so we consider the lean production with its osmotic interactions with the Japanese business system and we create a framework which highlights the key relations which are essential for the viability of the system.

Tra antichità e medioevo: viaggiatori, architetti e intellettuali in Sicilia fra gli anni venti e trenta dell’Ottocento

2016

Quando Eugène Emmanuel Viollet-le-Duc raggiunge la Sicilia nell’aprile del 1836 è un giovanissimo professore dell’Ecole de dessin de Paris in procinto di compiere quello che per numerosissimi suoi precursori era diventato, ormai da diversi decenni, una tappa obbligata del Grand Tour in Italia. Frotte di rampolli dell’aristocrazia europea, ma soprattutto artisti e cultori di antichità avevano attraversato negli anni precedenti le strade talvolta perigliose dell’isola alla ricerca delle vestigia di mitiche città come Agrigento, Siracusa, Selinunte ecc., spesso tenendo insieme passione ar- cheologica e gusto del pittoresco, come può testimoniare il vastissimo repertorio iconogra co che abbiamo…

Paesaggi e architetture nei disegni di Eugène E. Viollet-le-Duc. LE VOYAGE EN SICILE

2016

Il volume raccoglie il corpus dei disegni siciliani (oggi custoditi a Parigi presso la Médiathèque de l’architecture et du patrimoine) eseguiti da Viollet-le-Duc durante il suo soggiorno siciliano (1836) e si compone di una serie di saggi tematici relativi a diversi aspetti del suo viaggio di formazione, attraverso l'analisi diretta dei grafici e l'esame del contesto culturale nel quale egli opera.

Purified Membrane-Containing Procapsids of Bacteriophage PRD1 Package the Viral Genome

2009

Icosahedral-tailed double-stranded DNA (dsDNA) bacteriophages and herpesviruses translocate viral DNA into a preformed procapsid in an ATP-driven reaction by a packaging complex that operates at a portal vertex. A similar packaging system operates in the tailless dsDNA phage PRD1 (Tectiviridae family), except that there is an internal membrane vesicle in the procapsid. The unit-length linear dsDNA genome with covalently linked 5'-terminal proteins enters the procapsid through a unique vertex. Two small integral membrane proteins, P20 and P22, provide a conduit for DNA translocation. The packaging machinery also contains the packaging ATPase P9 and the packaging efficiency factor P6. Here we…

Combined effect of natural antioxidants and antimicrobial compounds during refrigerated storage of nitrite-free frankfurter-type sausage.

2019

Abstract The effects of nisin (200 and 400 ppm), e-polylysine (0.1 and 0.2%) and chitosan (0.5 and 1%) in combination with a Mixed Extract (green tea, stinging nettle and olive leaves extracts) on the physicochemical, microbiological characteristics, fatty acid composition and sensory attributes of the nitrite-free frankfurter-type sausages were assessed during 45 days of storage. The results revealed no significant differences on moisture, fat, protein, ash, salt and water activity (aw) among treatments. 1% Chitosan + Mixed Extract sausages displayed the lowest thiobarbituric acid reactive substances (TBARS) and total volatile nitrogen (TVN) values compared to Control after 45 days of refr…
