Socioekoloģiskās sistēmas pieeja pilsētas zaļās infrastruktūras plānošanā: Hunzes upes koridora piemērs Groningenā
2019
Pilsētu var uzskatīt par daudzšķautņainu organismu, kas pastāv pateicoties gan pilsētas ekosistēmas iekšējiem, gan arī ārējiem resursiem, taču pieaugot iedzīvotāju skaitam, noslogojums uz pilsētā pastāvošajām dabas teritorijām un kultūrmantojumu nemitīgi pieaug. Pilsētvide veidošanā tiek izmantoti stingri noteikti pārvaldības instrumenti, kā arī pilsētvides apsaimniekošanā tiek izmantoti tehniski pārvaldības risinājumi. Līdz ar to pilsētas kļūs par neelastīgām un izteikti cilvēku kontrolētām sistēmām, kuras zaudē spēju pielāgoties neprognozētu ārējo faktoru iedarbībai. Arī pilsētas kultūrvēsturiskās sejas zaudēšana atstāj nospiedumu uz vietas identitātes un labklājības jautājumiem. Tā iemes…
Group model building: a collaborative modelling methodology applied to critical infrastructure protection
2012
Large crises management, affecting CIs needs multidisciplinary knowledge including technical, economical, social, political, legal and managerial knowledge. Being these crises international a huge variety of agents is involved in their response. This situation concludes in a set of stakeholders who only have fragmented knowledge. In the presence of dispersed and incomplete knowledge, and of fragmented and disrupted crisis management, the collaborative approach group model building (GMB), where modelling experts unify fragmented, tacit knowledge from domain experts, is a valuable option. However, GMB has been little used in CIP. We have done so in the context a European project on crisis man…
Salt accumulation and effects within foliage of Tilia × vulgaris trees from the street greenery of Riga, Latvia
2020
International audience; Green infrastructures within sprawling cities provide essential ecosystem services, increasingly undermined by environmental stress. The main objective in this study was to relate the allocation patterns of NaCl contaminants to injury within foliage of lime trees mechanistically and distinguish between the effects of salt and other environmental stressors. Using field material representative of salt contamination levels in the street greenery of Riga, Latvia, the contribution of salt contaminants to structural and ultrastructural injury was analyzed, combining different microscopy techniques. On severely salt-polluted and dystrophic soils, the foliage of street lime …
From the vestiges port at the port hybrid: the experimental field of the waterfront 2.0
2012
Il contributo si propone di riflettere criticamente sulla possibilità di piani, programmi e progetti di riqualificare gli spazi portuali e di waterfront alla luce delle mutate condizioni del trasporto marittimo e passeggeri e in riferimento al conflitto tra funzioni portuali che richiedono spazi sempre maggiori e la crescita consolidata della città in cui il porto è inserito. L'armoniosa coesistenza di due realtà indipendenti, una porta attiva e una città viva, si sta tentando di raggiungere non solo attraverso l'unità fisica, ma generando flussi e sinergie. Il contributo esamina le aree di waterfront come campo di sperimentazione per un approccio sostenibile alle trasformazioni del territo…
Constructing Transnational Fields
2018
This chapter studies the evolving relationship between the redistribution of social resources and the structuration of institutional spaces beyond the nation-state. The author first discusses general features of transnational fields and then moves to an examination of the European Parliament as an empirical case. In this perspective, the object of this approach, transnational social fields, form the social infrastructure of globalization processes. They are historical constructions, subjected to a double historicity: the development of the position of the scholar and the development of the objects that she tries to elucidate in relation to other objects. Transnational fields enable the scho…
Friction forces and patient-centredness: Understanding how established logics endure during infrastructure transformation
2017
n this article, we examine three cases of e-health solutions for patients in Norway. For the analysis of the three cases, we focused on friction forces that come into play when different established arrangements need to change to accommodate novelty. We argue that the design of new technologies was shaped by friction related to institutionalised practices, regulatory regimes and entrenched patient roles. These friction forces connect the past with the present, come into action when aiming for novelty and result to the perpetuation of constituents of the past during change processes. Specifically, the e-health solutions under study were strongly influenced by established healthcare provision…
Proposal for the Reengineering of Processes in the Management of Information and Communication Technology
2019
This article describes the strategies implemented in the improvement of the processes in the management of information and communication technology (ICT) on the “Universidad Nacional de Loja” carried out by the “Unidad de Telecomunicaciones e Informacion” (UTI). First, the analysis of the processes carried out in the management of ICT is narrated. Subsequently, the experiences and best practices of information technology management implemented are described, considering the processes recommended by the Technology Infrastructure Library of Information (ITIL v3). Finally, the results obtained from the process of reengineering in ICT management carried out by the UTI are shown, using free soft…
Strategising IT service management through ITIL implementation: model and empirical test
2015
Research on the Information Technology Infrastructure Library (ITIL) lacks appropriate theories and models that capture the distinct characteristics and implications of the ITIL implementation practice. The purpose of this study is to close this gap. Based on a literature review, we develop and empirically validate a theoretical model: the ITIL Implementation Project Model. The model includes significant antecedents, which provide a foundation upon which an effective ITIL implementation project can be built, as well as the pertinent effects of implementing ITIL. The results contribute to the current research stream on the strategising of IT service management as well as to an improved under…
Cyber Situational Awareness in Critical Infrastructure Organizations
2021
The capability related to cybersecurity plays an ever-growing role on overall national security and securing the functions vital to society. The national cyber capability is mainly composed by resilience of companies running critical infrastructures and their cyber situational awareness (CSA). According to a common view, components of critical infrastructures become more complex and interdependent on each other and, as a consequence, ramifications of incidents multiply. In practice, the actions relate to developing better CSA and understanding of a critical infrastructure organization. The aim is to prepare for incidents and their management in a whole-of-society approach. The arrangement i…
Sulla strada tra Palermo e Agrigento / On the road between Palermo and Agrigento
2015
Il collegamento tra Palermo e Agrigento è un percorso antico già esistente in epoca romana e documentato anche nei secoli successivi. La costruzione della rotabile ha inizio nel 1779 ad opera dei Borboni e verrà completata solo dopo l’Unificazione. La storia e le trasformazioni della strada consentono di delineare le relazioni dell’infrastruttura con il paesaggio e i centri abitati che punteggiano l‘attraversamento e, soprattutto, con la campagna di cui la strada è sempre stata compagna continua. The ground connection between Palermo and Agrigento is an ancient path already existing in Roman times and well documented even in the following centuries. The road was first built in 1779 during B…
