Pouring new wine into old bottles: A dynamic perspective of the interplay among environmental dynamism, capabilities development, and performance
2022
In order to face increased environmental dynamism (ED), firms are increasingly called on to leverage deliberate learning processes that make dynamic capabilities emerge in a path-dependent way from the conversion of tacit knowledge to explicit knowledge. Moreover, to mitigate the effect that ED can play in eroding a firm's capabilities and subsequently its performance, managers need to effectively align short- and long-term strategies, which in the literature have been addressed as ‘capability traps’. Although these two processes are strictly interrelated, to date they have been treated in quite an isolated way and usually through the development of linear approaches. To fill this gap, leve…
The choice of offshoring operation mode: A behavioural perspective
2019
Since offshoring has recently become an integral part of corporate strategies, choosing the specific offshoring operation mode is a crucial aspect for CEOs. Using a sample of 466 offshoring operations, this study analyses offshoring mode decisions from the rationale of the Theory of Planned Behaviour (TPB). Drawing on this perspective, our results indicate that this decision seems to be clearly influenced by the manager's intentions and partially determined by some competences originated in the resources and experience of the firm. Additionally, and contrary to the common view in the field, our findings suggest that instead of being a possible intermediate option between the “make or buy” d…
Stereo Matching Tecniques for Cloud-top Height Retrieval
2006
This paper presents an ongoing study for the estimation of the cloud-top height by using only geometrical methods. It is based on the hypothesis that an infra-red camera is on board a satellite and pairs of images concern nearly the same scene. Stereo-vision techniques are therefore explored in order to test the methodology for height retrieval and in particular results of several techniques of stereo matching are evaluated. This study includes area-based matching algorithms by implementing the basic versions, without considering any further steps of optimisation to improve the results. Dense depth maps are the final outputs whose reliability is verified by computing error statistics with r…
Optimal placement of 3D sensors considering range and field of view
2017
This paper describes a novel approach to the problem of optimal placement of 3D sensors in a specified volume of interest. The coverage area of the sensors is modelled as a cone having limited field of view and range. The volume of interest is divided into many, smaller cubes each having a set of associated Boolean and continuous variables. The proposed method could be easily extended to handle the case where certain sub-volumes must be covered by several sensors (redundancy), for example ex-zones, regions where humans are not allowed to enter or regions where machine movement may obstruct the view of a single sensor. The optimisation problem is formulated as a Mixed-Integer Linear Program …
Enhanced viewing-angle integral imaging by multiple-axis telecentric relay system
2009
One of the main limitations of integral imaging is the narrow viewing angle. This drawback comes from the limited field of view of microlenses during the pickup and display. We propose a novel all-optical technique which allows the substantial increase of the field of view of any microlens and therefore of the viewing angle of integral-imaging displays.
Automatic production of three-dimensionnel models by 3D digitization
2012
The manual 3D digitization process is expensive since it requires a highly trained technician who decides about the different views needed to acquire the object model. The quality of the final result strongly depends, in addition to the complexity of the object shape, on the selected viewpoints and thus on the human expertise. Nowadays, the most developed digitization strategies in industry are based on a teaching approach in which a human operator manually determines one set of poses for the ranging device. The main drawback of this methodology is the influence of the operator's expertise. Moreover, this technique does not fulfill the high level requirement of industrial applications which…
Digital Picklock for Video Art Exgesis: Reflections, Conditions and Possible Employment of Distant Viewing to Moving Image Datasets in Visual Arts Sc…
2021
With the advent of digital humanities new expectations and challenges are emerging for institutions harbouring video artworks, specifically in offering access and analytical tools to their archival collections. The paper argues for the possible employment of distant viewing to allow visual arts scholars an unprecedented take on video art, holding together both quantitative comparison and aesthetic considerations. In doing so, the paper addresses the peculiar conditions of video art that need proper consideration for a fruitful employment of distant viewing. Set on the background of the existing platforms for video-art consumption ���such as UBU Network, JSC Media Centre, and Daata Streaming…

L'articolo reinterpreta la categoria narratologica di onniscienza applicata al campo della non-fiction e dopo un preambolo teorico si esaminano due casi particolari della narrativa italiana contemporanea: "Città sommersa" di Marta Barone e "La natura è innocente" di Walter Siti The article reinterprets the narratological category of omniscience applied to the field of non-fiction and after a theoretical preamble we examine two particular cases of contemporary Italian fiction: "Submerged city" by Marta Barone and "Nature is innocent" by Walter Siti
The road map toward an hepatitis C virus-free transplant population
2018
Antiviral therapy to eradicate hepatitis C virus (HCV) infection improves outcomes in patients undergoing liver transplantation (LT) for advanced chronic HCV with or without hepatocellular carcinoma. Traditionally, antiviral therapy focused on the use of interferon (IFN)-based regimens, with antiviral treatment initiated in the posttransplant period once recurrent HCV disease with fibrosis in the allograft was identified. The use of IFN-based therapy was limited in pretransplant patients with advanced liver disease. Earlier intervention, either before transplantation or early after LT, is now feasible with the advent of second-generation direct-acting antiviral agents (DAAs) with superior t…
