Processi di accumulazione e degrado del “capitale intellettuale” nel governo dello sviluppo aziendale Una prospettiva basata sulla dinamica delle ris…
2012
Sempre più spesso oggi le fonti del vantaggio competitivo dell’impresa non risiedono in singoli fattori della produzione (sebbene disponibili in quantità limitata, difficilmente imitabili o sostituibili da parte dei concorrenti), quanto piuttosto nella capacità di saper individuare e mantenere un opportuno dimensionamento quali-quantitativo di risorse strategiche tangibili e intangibili. Tra queste ultime, il “capitale intellettuale” assume una particolare rilevanza. Per comprendere i meccanismi sottostanti all’acquisizione di un vantaggio competitivo sostenibile è necessario cogliere i processi dinamici di accumulazione e degrado del “capitale intellettuale” e delle altre risorse strategic…
Enhancing Waste Governance through Dynamic Performance Management. An analysis of the Sicilian Waste System.
Supporting Multi-Sided Platform firms to maintain rapid growth (and to avoid failure) over time through a Dynamic Business Modelling approach
2020
Over the last few decades, the diffusion of the sharing economy has nurtured continuous changes in business model opportunities with multi-sided platforms (MSPs) in many industries. MSPs are digital exchange platforms aiming at connecting unmatched demand- and supply- side participants through the use of internet technology. In many cases, such start-up initiatives have led to the creation of scale-up or high-growth firms (HGFs). However, in spite of the significant contribution to both economic development and employment, current studies seem to investigate primarily in an isolated perspective HGFs, MSPs and their business model innovation (BMI). The existing literature on HGFs focuses on …
Ultrasonic characterisation of poroux materials
2017
International audience; Acoustic models of the acoustics of porous and perforated media involve a set of physical parameters. Some of the parameters, the tortusity, the viscous and thermal characteristic lengths are defined for a perfect incompressible and inviscid fluid saturating the porous medium. It is shown that ultrasonic propagation in air-saturated materials can be used to determine these parameters. A basic method involving air-coupled ultrasonic transducers is presented. Variants of this method and a practical implementation of one of these is proposed.
Talis pater, talis filius: the role of discursive strategies, thematic narratives and ideology in Cosa Nostra
2018
The discursive analysis of criminal organizations’ family dynamics and ideological devices may provide important insights into the inner functioning of these groups. In this article, we describe and analyze a specific set of discursive strategies and the thematic narratives emerging from a TV interview with Giuseppe Riina, a member of Cosa Nostra and the son of one of the most important mafia bosses. Our analyses demonstrate the existence of recurring ideological devices such as reductionism, amoralism, familism, verticalism, normalism, victimism and religious relativism. The results are discussed in light of previous research that examines how discursive strategies and narratives may repre…
Integrating Keyword Advertising and Dynamic Pricing for an Online Market Place
2014
Keyword Advertising is a main marketing instrument for e-commerce companies in order to generate traffic from search engines on their website. The costs for Keyword Advertising are determined in an auction that is conducted for every single search query, which is entered in by a user. In case of an online market place, each adlink provided by the search engine refers to an ordered list of products on the website of the online market place. Hereby, the price of the product is oftentimes one important criteria for the user when deciding for one or the other product from the list. However, existing models assume the price of products to be exogeneous. By taking into account the prices of linke…
Development of core-shell colloids to study self-diffusion in highly concentrated dispersions
2007
To study single particle motion in highly concentrated colloidal dispersions, a host-tracer colloid system was developed, consisting of crosslinked polymer micronetwork spheres placed in a good solvent. The host colloid is made invisible to the experimental probe by matching its refractive index to that of the solvent. For the tracer particles a core-shell structure was chosen to ensure the interaction potential to be identical to that of the host particles. Therefore the shell was made of the same polymer as the host. The core differs in refractive index from the solvent and is therefore visible due to scattered light.
EFFECT OF SHAPE ON POTATO AND CAULIFLOWER SHRINKAGE DURING DRYING
2000
ABSTRACT Shrinkage of potato cubes, parallelepipeds and cylinders was addressed during drying. A basic methodology by using image analysis was set-up in order to measure and monitor geometrical changes along the drying process. Both measurements by image analysis and directly with a calliper were carried out. Results from both methods showed a good agreement with no bias. Particle shape was found to influence shrinkage in a different way according to the axis. In fact the larger dimension shrinks less than the shorter one. This could be linked to the influence of the core drying in shrinkage. Experiments were also carried out for cauliflower stems. The difference in shrinkage between direct…
Measurement of the Soft-Drop Jet Mass in pp Collisions at s=13 TeV with the ATLAS Detector
2018
Jet substructure observables have significantly extended the search program for physics beyond the standard model at the Large Hadron Collider. The state-of-the-art tools have been motivated by the ...
