Distribution of Caulerpa taxifolia var. distichophylla (Sonder) Verlaque, Huisman & Procaccini in the Mediterranean Sea
2019
The Non-Indigenous Species (NIS) Caulerpa taxifolia var. distichophylla (Sonder) Verlaque, Huisman & Procaccini has been reported for the first time in the Mediterranean Sea along the coast of South Turkey. This NIS is actively expanding into the Eastern and Western Mediterranean Sea. In this paper, we present an overview of the current distribution of this alga in the Mediterranean Sea, based on relevant scientific publications, grey literature and personal observations. New records from the Sicilian coast (Italy) are also reported. Caulerpa taxifolia var. distichophylla was found over a wide range of environmental conditions (depth, light and substratum), suggesting a broad ecolog…
Understanding the Importance of Proper Incentives for Critical Infrastructures Management – How System Dynamics Can Help
2016
International audience; Computer and information systems are now at the core of numerous critical infrastructures. However, their security management is by far not a trivial issue. Further, these systems, by their very nature, belong to the domain of complex systems, where system dynamics (SD) is an established method, which aims at modelling such systems, their analysis and understanding. Further, on this basis it enables simulation of various policies to properly manage complex systems. More precisely, through understanding of the basic elements of the whole mosaic and their interplay, proper incentives can be tested. And this is important, because proper incentives can lead to the desire…
Standardisation and social ordering: A change of perspective
2021
This article examines standardisation in synthetic biology as a form of social coordination and ordering. I discuss standardisation by exploring what makes standards possible, and offer an understanding based on infrastructures: technical and social systems that support the existence and operation of accepted standards. By exploring the role of social infrastructures, I contend that standards depend upon social ordering: ways of arranging people in particular positions, relations, and hierarchies. I suggest that synthetic biologists ought to develop an awareness of these social orders, take responsibility for their creation, and accept accountability for their consequences, both technical a…
A comparative analysis between helicopter and seaplane for passenger transport.
2016
Purpose This study aims to develop a methodology to compare the feasibility of helicopter and seaplane regular transport of passengers towards destinations across a remote regional tourist context, where a lack of road and rail infrastructure make these alternative forms of air transport competitive. Design/methodology/approach The authors use a modal split model identifying the quota of passengers that potentially could utilize these two types of services, determined on the basis of previous studies on air transport demand. A technical analysis regarding transport supply is performed to identify the predominant features that should characterize helicopter/seaplane performances. An optimiza…
L'action publique et les réseaux de transport au Sahara algérien, étapes d'une intégration territoriale pour un développement régional
2008
Aujourd'hui espace d'enjeux géostratégiques, le Sahara représente pour l'Algérie, comme pour les différents états du Maghreb, un hinterland porteur et vecteur de développement économique. Champs pétroliers, ressources en minerais et aquifères souterrains sont autant d'éléments qui, combinés à des considérations géopolitiques nationales et internationales, ont justifié une intégration au territoire national des vastes espaces sahariens. Au lendemain de l'indépendance algérienne (1962), l'appropriation et l'intégration de ces espaces sahariens constituèrent des enjeux capitaux dans la construction de l'État-nation, celui-ci devant s'appuyer tout d'abord sur un territoire unifié et maîtrisé. L…
Special Issue “Smart Urban Lighting Systems”
2020
The design and operation of multifunctional infrastructures for public lighting as well as their impact on the urban environment and citizens’ life is today of great interest. The cost of energy for public lighting is often an issue for the budget of municipalities. Furthermore, researchers’ and designers’ attention is increasingly focused on aspects of public lighting not directly valuable through economic factors. Starting from the “quality” of the light environment, looking at citizens’ visual comfort, the light has to be considered as an instrument to improve the urban context and objects therein (including buildings). Indeed, urban degradation (lack of infrastructures, maintenance, ser…
ISIM - INFRASTRUCTURES & STRUCTURES INFORMATION MODELING: A NEW CONCEPT OF BIM FOR INFRASTRUCTURES
2023
The application of Building Information Modeling (BIM) in infrastructure and structural projects, known as Integrated Structural and Infrastructure Modeling (ISIM), has gained attention in recent years due to its potential to revolutionize the construction industry. By providing a digital representation of the built environment, BIM allows for improved collaboration and communication between project stakeholders, leading to enhanced project outcomes. The ISIM approach is centered on the creation of a digital twin, a three-dimensional model of the infrastructure or structure, which serves as a virtual replica of the physical asset. This digital twin provides a platform for analysis, decision…
The Porto European Cancer Research Summit 2021.
2021
Key stakeholders from the cancer research continuum met in May 2021 at the European Cancer Research Summit in Porto to discuss priorities and specific action points required for the successful implementation of the European Cancer Mission and Europe's Beating Cancer Plan (EBCP). Speakers presented a unified view about the need to establish high‐quality, networked infrastructures to decrease cancer incidence, increase the cure rate, improve patient's survival and quality of life, and deal with research and care inequalities across the European Union (EU). These infrastructures, featuring Comprehensive Cancer Centres (CCCs) as key components, will integrate care, prevention and research acros…
Aproximación a la Geografía del despilfarro en España: balance de las últimas dos décadas
2018
Este trabajo pretende ser una primera aproximación a la dimensión del despilfarro de recursos públicos en infraestructuras en España desde 1995 hasta la actualidad en los distintos niveles de gobierno. A partir de algunas precisiones sobre los conceptos de despilfarro y corrupción, se analiza, de una parte, la inversión y los sobrecostes en infraestructuras innecesarias impulsadas y ejecutadas por la Administración General del Estado en el ámbito de sus competencias, y de otra, infraestructuras, proyectos, eventos e inversiones fallidas, vacías o infrautilizadas acometidas por las Comunidades Autónomas y los gobiernos locales. Se abordan los déficit de marco institucional y de gobernanza te…
Simulations of networked critical infrastructures
2018
Master's thesis Information- and communication technology IKT590 - University of Agder 2018 Critical infrastructure (CI) refers to assets that are essential for the functioning of a society and economy, such as telecommunication/ICT; energy generation, transmission and distribution; financial sector; etc. CIs are tightly coupled, creating a complex system where failures propagate from a disrupted CI to other CIs, aggravating and prolonging the societal impact through cascading effects. This thesis extends a system dynamic model by Eliza Canzani describing how a failed critical infrastructure that cannot deliver products and services impacts other critical infrastructures, and how a critical…
