Towards a routine-based view of interfirm rivalry
2022
Although organizational routines have attracted increasing attention in strategy and organization research, they have received surprisingly limited attention in competitive dynamics scholarship. Our essay seeks to advance a routine-based view of interfirm rivalry by bridging the competitive dynamics and routine literatures. We put forward a conceptual model of the routine-based view of interfirm rivalry that is centered on “competitive action routines.” The model clarifies the roles that managers play in driving a firm’s competitive behavior, challenges the assumption of routine-based rigidity in competitive behavior, and adds nuance to our understanding of managerial cognition in competiti…
Application of Broadband Dielectric Spectroscopy to Cultural Heritage: characterization and preservation of ancient paper artwork
2016
Within the cultural heritage the characterization and conservation of artworks based on paper represents a significant issue for both restorers and scientists. The paper deterioration is affected by the degree of hydrolytic and oxidative reactions which occur upon aging. Moreover, the durability of cellulose fibers depends on the intrinsic composition/structure of the paper as well as on the conservation conditions, such as temperature and humidity. The structural and dynamical characterization of the cellulose matrix and of the water confined within its pores is therefore of central interest. Our working hypothesis is that WATER DYNAMICS is one of the main determinants of paper degradation…
Institutional Path Dependence in Competitive Dynamics: The Case of Paper Industries in Finland and the USA
2017
Prior research on competitive dynamics has failed to offer tools to understand distorted patterns of competition that emerge from distinct institutional and historical contexts. Our analysis suggests that a joint effect of institutional rules, governance structures, and shared cognition plays a pivotal role in firm-level competitive behavior and capability development. We show how globally significant market positions can result from specific institutional arrangements between firms and governments, especially if coupled with interfirm contractual commitments. Our results call for more attention to these interfirm commitments that are built on formal rules and governmental support, but whos…
Evolutionary Dynamics of Pathoadaptation Revealed by Three Independent Acquisitions of the VirB/D4 Type IV Secretion System in Bartonella
2017
The α-proteobacterial genus Bartonella comprises a group of ubiquitous mammalian pathogens that are studied as a model for the evolution of bacterial pathogenesis. Vast abundance of two particular phylogenetic lineages of Bartonella had been linked to enhanced host adaptability enabled by lineage-specific acquisition of a VirB/D4 type IV secretion system (T4SS) and parallel evolution of complex effector repertoires. However, the limited availability of genome sequences from one of those lineages as well as other, remote branches of Bartonella has so far hampered comprehensive understanding of how the VirB/D4 T4SS and its effectors called Beps have shaped Bartonella evolution. Here, we repor…
HDR-ARtiSt: a FPGA-based Smart Camera for High Dynamic Range color video from multiple exposures
2014
International audience; A camera is able to capture only a part of a high dynamic range scene information. The same scene can be fully perceived by the human visual system. This is true especially for real scenes where the difference in light intensity between the dark areas and bright areas is high. The imaging technique which can overcome this problem is called HDR (High Dynamic Range). It produces images from a set of multiple LDR images (Low Dynamic Range), captured with different exposure times. This technique appears as one of the most appropriate and a cheap solution to enhance the dynamic range of captured environments. We developed an FPGA-based smart camera that produces a HDR liv…

Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEM) of a Customized Stent-Graft for Endovascular (EVAR) Treatment of Abdominal Aorti…
2023
Background: The treatment of abdominal aortic aneurysm (AAA) is today commonly treated by inserting a stent-graft by the endovascular route, without resorting to open surgery. However, some clinical cases do not allow this less invasive approach, meaning that the stent-graft cannot be inserted and open surgery is used. Methods: In the study, we propose a fluid–structure interaction (FSI) analysis of an aneurysmatic aorta that could not be treated with Endovascular Aneurysm Repair (EVAR). The vessel is reconstructed through segmentation from CT scans and subsequently modeled on CAD software to create the surface and thickness of the vessel itself. Subsequently, we proceeded to carry out Comp…
“Dealing With Patients’ Mobility Issues: An Inter-Institutional Perspective To Analyze The Phenomenon And To Support Sustainable Policy Making In Sic…
2014
Nowadays many Italian policy makers, both at a national and regional level, are devoting a growing attention to the phenomenon of patients’ movements seeking public healthcare treatments out of the territorial jurisdiction. This paper presents the main features of a research project being carried out to analyze the mobility flows of Sicilian patients towards other Italian Regions in order to support the design of sustainable related policies. Such study adopts an inter-institutional perspective as the design of sustainable mobility-related policies requires a coordination effort of the Regional Healthcare Department, the Local Health Authorities and the Healthcare providers. The main outcom…
Reconceptualising the Role of Talk in CLIL
2011
This theoretical paper offers a reconceptualisation of talk in CLIL based on sociocultural and dialogic theories of education. Building on these educational theories and the experiences of an on-going CLIL project, this paper presents a pedagogical model for the navigation of the ‘talkscape’ of the CLIL classroom. This model comprises a total of seven talk-types: organisational, social, critical, expert, exploratory, meta and pedagogic. In addition to these talk-types, the paper introduces the notion of a ‘transitional dynamic’. This notion aims to capture the transition from first language to foreign language use in CLIL both within the context of individual courses and across a broader CL…
An Ecological Conceptualization of Extreme Sports
2018
Currently, there are various definitions for extreme sports and researchers in the field have been unable to advance a consensus on what exactly constitutes an ‘extreme’ sport. Traditional theory-led explanations, such as edgeworks, sensation seeking and psychoanalysis, have led to inadequate conceptions. These frameworks have failed to capture the depth and nuances of experiences of individuals who refute the notions of risk-taking, adrenaline- and thrill-seeking or death-defiance. Instead, participants are reported to describe experiences as positive, deeply meaningful and life-enhancing. The constant evolution of emerging participation styles and philosophies, expressed within and across…
